Each of the Company and its Subsidiaries has timely filed or caused to be timely filed all tax returns and reports that are required to have been filed in any jurisdiction, and has paid all taxes shown to be due and payable on such returns and all other taxes and assessments payable by them, to the extent such taxes and assessments have become due and payable and before they have become delinquent, except for any taxes and assessments, the amount, applicability or validity of which is currently being contested in good faith by appropriate proceedings and with respect to which the Company or such Subsidiary, as the case may be, has established adequate reserves in accordance with GAAP. The charges, accruals and reserves on the books of the Company and its Subsidiaries in respect of taxes and other governmental charges are, in the reasonable opinion of the Company, adequate. No tax Lien has been filed and, to the knowledge of the Company, no claim is being asserted with respect to any such tax or other such governmental charge. (n) Properties; Titles; Etc. (i) Each of the Company and the Subsidiaries has good and defensible title to the Oil and Gas Properties evaluated in the most recently delivered Engineering Report and good title to all its personal Properties, in each case, free and clear of all Liens except Permitted Liens. After giving full effect to the Permitted Liens, the Company or the Subsidiary specified as the owner owns the net interests in production attributable to the Hydrocarbon Interests as reflected in the most recently delivered Engineering Report, and the ownership of such Properties shall not in any material respect obligate the Company or such Subsidiary to bear the costs and expenses relating to the maintenance, development and operations of each such Property in an amount in excess of the working interest of each Property set forth in the most recently delivered Engineering Report that is not offset by a corresponding proportionate increase in the Company's or such Subsidiary's net revenue interest in such Property. (ii) All material leases and agreements necessary for the conduct of the business of the Company and the Subsidiaries are valid and subsisting, in full force and effect, and there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give rise to a default under any such lease or leases, which could reasonably be expected to have a Material Adverse Effect. (iii) The rights and Properties presently owned, leased or licensed by the Company and the Subsidiaries including, without limitation, all easements and rights of way, 12 include all rights and Properties necessary to permit the Company and the Subsidiaries to conduct their business in all material respects in the same manner as its business has been conducted prior to the date hereof. (iv) All of the Properties of the Company and the Subsidiaries which are reasonably necessary for the operation of their businesses are in good working condition and are maintained in accordance with prudent business standards. (v) The Company and each Subsidiary owns, or is licensed to use, all trademarks, tradenames, copyrights, patents and other intellectual Property material to its business, and the use thereof by the Company and such Subsidiary does not infringe upon the rights of any other Person, except for any such infringements that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. The Company and its Subsidiaries either own or have valid licenses or other rights to use all databases, geological data, geophysical data, engineering data, seismic data, maps, interpretations and other technical information used in their businesses as presently conducted, subject to the limitations contained in the agreements governing the use of the same, which limitations are customary for companies engaged in the business of the exploration and production of Hydrocarbons, with such exceptions as could not reasonably be expected to have a Material Adverse Effect. (o) Maintenance of Properties. Except for such acts or failures to act as could not be reasonably expected to have a Material Adverse Effect, the Oil and Gas Properties (and Properties unitized therewith) have been maintained, operated and developed in a good and workmanlike manner and in conformity with all Government Requirements and in conformity with the provisions of all leases, subleases or other contracts comprising a part of the Hydrocarbon Interests and other contracts and agreements forming a part of the Oil and Gas Properties. Specifically in connection with the foregoing, except for those as could not be reasonably expected to have a Material Adverse Effect, (i) no Oil and Gas Property is subject to having allowable production reduced below the full and regular allowable (including the maximum permissible tolerance) because of any overproduction (whether or not the same was permissible at the time) and (ii) none of the wells comprising a part of the Oil and Gas Properties (or Properties unitized therewith) is deviated from the vertical more than the maximum permitted by Government Requirements, and such wells are, in fact, bottomed under and are producing from, and the well bores are wholly within, the Oil and Gas Properties (or in the case of wells located on Properties unitized therewith, such unitized Properties). All pipelines, wells, gas processing plants, platforms and other material improvements, fixtures and equipment owned in whole or in part by the Company or any of its Subsidiaries that are necessary to conduct normal operations are being maintained in a state adequate to conduct normal operations, and with respect to such of the foregoing which are operated by the Company or any of its Subsidiaries, in a manner consistent with the Company's or its Subsidiaries' past practices (other than those the failure of which to maintain in accordance with this Section 5.1(o) could not reasonably be expect to have a Material Adverse Effect). (p) Gas Imbalances; Prepayments. On a net basis there are no gas imbalances, take or pay or other prepayments which would require the Company or any of its Subsidiaries to deliver Hydrocarbons produced from the Oil and Gas Properties at some future time without then 13 or thereafter receiving full payment therefor exceeding one-half bcf of gas (on an mcf equivalent basis) in the aggregate. (q) Marketing of Production. The Company's principal long-term production sales agreements are described on the Disclosure Schedule. Except for contracts listed and in effect on the date hereof on the Disclosure Schedule, and thereafter either disclosed in writing to the Collateral Agent and the Purchasers or included in the most recently delivered Engineering Report (with respect to all of which contracts the Company represents that it or its Subsidiaries are receiving a price for all production sold thereunder which is computed substantially in accordance with the terms of the relevant contract and are not having deliveries curtailed substantially below the subject Property's delivery capacity), no material agreements exist which are not cancelable on 60 days notice or less without penalty or detriment for the sale of production from the Company's or its Subsidiaries' Hydrocarbons (including, without limitation, calls on or other rights to purchase, production, whether or not the same are currently being exercised) that (i) pertain to the sale of production at a fixed price and (ii) have a maturity or expiry date of longer than six (6) months from the date hereof. (r) Insurance. The Company has, and has caused all its Subsidiaries to have, (i) all insurance policies sufficient for the compliance by each of them with all material Governmental Requirements and all material agreements and (ii) insurance coverage in at least amounts and against such risk (including, without limitation, public liability) that are usually insured against by companies similarly situated and engaged in the same or a similar business for the assets and operations of the Company and its Subsidiaries.

Fortis Benefits Life Insurance Plan, (3) the Quicksilver Resources Inc. Fortis Benefits Health Insurance Plan, (4) the Quicksilver Resources Inc. Blue Cross Blue Shield of Michigan Health Insurance Plan, and (5) the Quicksilver Resources Inc. American Medical Security Dental Plan. (ii) The Company and each ERISA Affiliate have operated and administered each Plan in compliance with all applicable laws except for such instances of noncompliance as have not resulted in and could not reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in Section 3 of ERISA), and no event, transaction or condition has occurred or exists that would reasonably be expected to result in the incurrence of any such liability by the Company or any ERISA Affiliate, or in the imposition of any Lien on any of the rights, Properties or assets of the Company or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or 412 of the Code, other than such liabilities or Liens as would not be individually or in the aggregate material. 14 (iii) The Company and its ERISA Affiliates do not maintain (and in the past five (5) years have not maintained) any Plan subject to Title IV of ERISA or Section 412 of the Code. The Company and its ERISA Affiliates have made all contributions to, and paid all benefits with respect to, all Plans, to the extent they are or were required to do so. To the extent that the Company and its Subsidiaries have any accrued liabilities with respect to any Plans, such liabilities are properly reported on the Company's Consolidated balance sheet. (iv) The Company and its ERISA Affiliates do not maintain and have never participated in or been required to make contributions to any Multiemployer Plan, and the Company and its ERISA Affiliates have not incurred withdrawal liabilities (and are not subject to contingent withdrawal liabilities) under section 4201 or 4204 of ERISA in respect of Multiemployer Plans that individually or in the aggregate are material. (v) The expected postretirement benefit obligation (determined as of the last day of the Company's most recently ended fiscal year in accordance with Financial Accounting Standards Board Statement No. 106, without regard to liabilities attributable to continuation coverage mandated by section 4980B of the Code and based on reasonable assumptions in light of actual circumstances) of the Company and its Subsidiaries is not material. (vi) The execution and delivery of this Agreement and the issuance and sale of the Notes hereunder will not involve any transaction that is subject to the prohibitions of section 406 of ERISA or in connection with which a tax could be imposed pursuant to section 4975(c)(l)(A)-(D) of the Code. The representation by the Company in the first sentence of this Section 5.1(s)(vi) is made in reliance upon and subject to the accuracy of each Purchaser's representation in Section 6.2 as to the sources of the funds to be used to pay the purchase price of the Notes to be purchased by such Purchaser. (t) Private Offering by the Company. Neither the Company nor anyone acting on its behalf has offered the Notes or any similar securities for sale to, or solicited any offer to buy any of the same from, or otherwise approached or negotiated in respect thereof with, any Person other than the Purchasers and not more than 65 other Institutional Investors, each of which has been offered the Notes at a private sale for investment. Neither the Company nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the Notes to the registration requirements of Section 5 of the Securities Act. (u) Use of Proceeds; Margin Regulations. The proceeds of the Notes shall be used, in part, to repay the Senior Mortgage Notes. The Company and its Subsidiaries are not engaged principally, or as one of its or their important activities, in the business of extending credit for the purpose, whether immediate, incidental or ultimate, of buying or carrying margin stock (within the meaning of Regulation T, U or X of the Board). No part of the proceeds of the Notes will be used for any purpose which violates the provisions of Regulations T, U or X of the Board. In no event shall the proceeds of the sale of the Notes be used directly or indirectly by any of the Company or its Subsidiaries for personal, family, household or agricultural purposes or for the purpose, whether immediate, incidental or ultimate, of purchasing, acquiring or carrying any "margin stock" (as such term is defined respectively in Regulation U promulgated by the Board of Governors of the Federal Reserve System) or to extend credit to others directly or indirectly for the purpose of purchasing or carrying any such margin stock, or for the purpose 15 of buying or carrying or trading in any securities under such circumstances as to involve the Company or any of its Subsidiaries in a violation of Regulation X of said Board or to involve any broker or dealer in a violation of Regulation T of said Board. Margin stock does not constitute more than 25% of the value of the consolidated assets of the Company and its Subsidiaries and the Company does not have any present intention that margin stock will constitute more than 25% of the value of such assets. (v) Foreign Assets Control Regulations, etc. Neither the sale of the Notes by the Company hereunder nor its use of the proceeds thereof will violate the Trading with the Enemy Act, as amended, or any of the foreign assets control regulations of the United States Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling legislation or executive order relating thereto.

(iii) Neither the Company nor any Subsidiary of the Company is subject to regulation under the Interstate Commerce Act, as amended, or the Federal Power Act, as amended. (x) Hedging Contracts.

(y) Solvency. After giving effect to the transactions contemplated hereby, (i) the aggregate assets (after giving effect to amounts that could reasonably be received by reason of indemnity, offset, insurance or any similar arrangement), at a fair valuation, of the Company and the Guarantors, taken as a whole, will exceed the aggregate Debt of the Company and the Guarantors on a consolidated basis, as the Debt becomes absolute and matures, (ii) each of the Company and the Guarantors will not have incurred or intended to incur, and will not believe that it will incur, Debt beyond its ability to pay such Debt (after taking into account the timing and amounts of cash to be received by each of the Company and the Guarantors and the amounts to be payable on or in respect of its liabilities, and giving effect to amounts that could reasonably be received by reason of indemnity, offset, insurance or any similar arrangement) as such Debt becomes absolute and matures and (iii) each of the Company and the Guarantors will not have 16 (and will have no reason to believe that it will have thereafter) unreasonably small capital for the conduct of its business.

(aa) Delivery of Bank Credit Agreement. The Company has delivered to each Purchaser and the Collateral Agent a true, correct and complete copy of the Bank Credit Agreement, including all amendments and waivers of any provision thereof. Each delivery of the financial statements required to be delivered by the Company pursuant to Section 8.1(b)(i) and Section 8.1(b)(ii) shall be deemed to constitute a representation and warranty by the Company on such date of delivery that the representations and warranties of the Company and the Guarantors set forth in this Agreement and in the other Transaction Documents are true and correct on and as of such date of delivery, except to the extent any such representations and warranties are expressly limited to an earlier date, in which case, on and as of such date of delivery, such representations and warranties shall continue to be true and correct as of such specified earlier date. ARTICLE VI. REPRESENTATIONS OF THE PURCHASERS Section 6.1. Purchase for Investment. Each Purchaser represents that such Purchaser is purchasing the Notes for such Purchaser's own account or for one or more separate accounts maintained by such Purchaser or for the account of one or more pension or trust funds and not with a view to the distribution thereof, provided that the disposition of such Purchaser's or their Property shall at all times be within such Purchaser's or their control.

ARTICLE VII. PAYMENTS OF PRINCIPAL AND INTEREST; PREPAYMENTS; OFFERS TO PURCHASE Section 7.1. Interest. 18 (a) Fixed Rate Notes. Each Fixed Rate Note shall bear interest at a rate per annum equal to 7.50%. (b) Floating Rate Notes. Each Floating Rate Note shall bear interest at the Adjusted LIBO Rate plus the Applicable Margin. Notwithstanding the foregoing, if prior to the commencement of any Interest Period for a Floating Rate Note: (i) the Collateral Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate for such Interest Period; or (ii) the Collateral Agent is advised by a majority of the Holders of the Floating Rate Notes that the Adjusted LIBO Rate or LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Holders of maintaining their investment in such Notes for such Interest Period; then the Collateral Agent shall give notice thereof to the Company and the Holders of the Floating Rate Notes by telephone or telecopy as promptly as practicable thereafter and, until the Collateral Agent notifies the Company and the Holders of the Floating Rate Notes that the circumstances giving rise to such notice no longer exist, the Floating Rate Notes shall bear interest at the Alternate Base Rate plus the Applicable Margin. (c) Post-Default Rate. Notwithstanding anything to the contrary contained herein, during the continuation of an Event of Default, interest shall accrue at the Default Rate. Section 7.2. Regular Interest Payments. On each Quarterly Payment Date commencing with September 30, 2003, the Company shall pay to each Holder in immediately available funds all unpaid interest which has accrued on such Holder's Note to but not including such Quarterly Payment Date. Section 7.3. No Make-Whole Amount for Floating Rate Notes. Notwithstanding anything to the contrary contained herein, in no event shall any Holder of a Floating Rate Note be entitled to receive in respect of its Floating Rate Note any Make-Whole Amount under any circumstances in which the payment of a Make-Whole Amount is required by the Company hereunder. Section 7.4. Principal Repayment at Maturity. The entire principal amount of each Note remaining outstanding on the Maturity Date, together with accrued and unpaid interest thereon, will be due and payable on such date. Section 7.5. Optional Prepayments. The Company may, at its option, upon notice as provided below, prepay at any time all, or from time to time any part of, the Notes, in an amount not less than $5,000,000 and in integral multiples of $1,000,000 in the case of a partial prepayment, at 100% of the principal amount so prepaid, plus interest thereon to the prepayment date, plus, in the case of Fixed Rate Notes, the Make-Whole Amount determined for the prepayment date with respect to such principal amount. The Company will give each Holder written notice of each optional prepayment under this Section 7.5 not less than 30 days and not more than 60 days prior to the date fixed for such prepayment. Each such notice shall specify 19 such date, the aggregate principal amount of the Notes to be prepaid on such date, the principal amount of each Note held by such Holder to be prepaid (determined in accordance with Section 7.6), and the interest to be paid on the prepayment date with respect to such principal amount being prepaid, and, in the case of Fixed Rate Notes, shall be accompanied by a certificate of the chief financial officer of the Company as to the estimated Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to such prepayment, the Company shall deliver to each Holder of Fixed Rate Notes a certificate of the chief financial officer of the Company specifying the calculation of such Make-Whole Amount as of the specified prepayment date. Section 7.6. Allocation of Partial Prepayments. In the case of each partial prepayment of the Notes, the principal amount of the Notes to be prepaid shall be allocated among all of the Notes at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment. Section 7.7. Maturity; Surrender, Etc. In the case of each prepayment of Notes pursuant to Section 7.5 and Section 7.10, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment, together with interest on such principal amount accrued to such date and, in the case of Fixed Rate Notes, the applicable Make-Whole Amount. From and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and, in the case of Fixed Rate Notes, Make-Whole Amount, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note. Section 7.8. Purchase of Notes. The Company will not and will not permit any Affiliate to purchase, Redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except upon the payment or prepayment of the Notes in accordance with the terms of this Agreement and the Notes. The Company will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to any provision of this Agreement and no Notes may be issued in substitution or exchange for any such Notes. Section 7.9. Make-Whole Amount. The term "Make-Whole Amount" means, with respect to any Fixed Rate Note, an amount equal to the greater of (a) the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Fixed Rate Note over the amount of such Called Principal and (b) 2% of the Called Principal of such Fixed Rate Note. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings: "Called Principal" means, with respect to any Fixed Rate Note, the principal of such Fixed Rate Note that is to be prepaid pursuant to Section 7.5 or Section 7.10 or has become or is declared to be immediately due and payable pursuant to Section 10.3, as the context requires. 20 "Discounted Value" means, with respect to the Called Principal of any Fixed Rate Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Fixed Rate Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal. "Reinvestment Yield" means, with respect to the Called Principal of any Fixed Rate Note, 1.0% over the yield to maturity implied by (a) the yields reported, as of 10:00 A.M. (New York City time) on the Business Day next preceding the Settlement Date with respect to such Called Principal for actively traded U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date on the Treasury Yield Monitor page of Standard & Poor's MMS - Treasury Market Insight (or, if Standard & Poor's shall cease to report such yields in MMS - Treasury Market Insight or shall cease to be the Majority Purchasers' customary source of information for calculating yield-maintenance amounts on privately placed notes, then such source as is then the Majority Purchasers' customary source of such information), or (b) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable, the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the Business Day next preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (519) (or any comparable successor publication) for actively traded U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. Such implied yield will be determined, if necessary, by (i) converting U.S. Treasury bill quotations to bond-equivalent yields in accordance with accepted financial practice and (ii) interpolating linearly between yields reported for various maturities. The Reinvestment Yield shall be rounded to that number of decimal places as appears in the coupon of the applicable Fixed Rate Note. "Remaining Average Life" means, with respect to any Called Principal, the number of years obtained by dividing (a) such Called Principal into (b) the sum of the products obtained by multiplying (i) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (ii) the number of years that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment. "Remaining Scheduled Payments" means, with respect to the Called Principal of any Fixed Rate Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Fixed Rate Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 7.5, Section 7.10 or Section 10.3. 21 "Settlement Date" means, with respect to the Called Principal of any Fixed Rate Note, the date on which such Called Principal is to be prepaid pursuant to Section 7.5 or Section 7.10 or has become or is declared to be immediately due and payable pursuant to Section 10.3, as the context requires. Section 7.10. Offer to Prepay Notes in the Event of a Change of Control. (a) Notice of Impending Change of Control. The Company will not consummate a Change of Control unless at least 30 days prior to such action it shall have given to the Collateral Agent and each Holder written notice of such impending Change of Control. (b) Notice of Occurrence of Change of Control. The Company will, within five Business Days after any Responsible Officer has knowledge of the occurrence of any Change of Control, give written notice of such Change of Control to the Collateral Agent and each Holder. If a Change of Control has occurred, such notice shall contain an offer to prepay the Notes as described in Section 7.10(c) and shall be accompanied by the certificate described in Section 7.10(f). (c) Offer to Prepay Notes. The offer to prepay Notes contemplated by Section 7.10(b) shall be an offer to prepay, in accordance with and subject to this Section 7.10, all, but not less than all, the Notes held by each Holder (in this case only, "Holder" in respect of any Note registered in the name of a nominee for a disclosed beneficial owner shall mean such beneficial owner) on a date specified in such offer (the "Proposed Prepayment Date"). Such Proposed Prepayment Date shall be not less than 30 days and not more than 60 days after the date of such offer (if the Proposed Prepayment Date shall not be specified in such offer, the Proposed Prepayment Date shall be the 30th day after the date of such offer). (d) Rejection; Acceptance. A Holder shall accept or reject the offer to prepay made pursuant to this Section 7.10 by causing a notice of such acceptance or rejection to be delivered to the Company at least five days prior to the Proposed Prepayment Date. A failure by a Holder to respond to an offer to prepay made pursuant to this Section 7.10 shall be deemed to constitute an acceptance of such offer by such Holder. (e) Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 7.10 shall be at 100% of the principal amount of such Notes, together with interest on such Notes accrued to the date of prepayment and, in the case of Fixed Rate Notes, the Make-Whole Amount with respect to each Fixed Rate Note. The prepayment shall be made on the Proposed Prepayment Date. (f) Officer's Certificate. Each offer to prepay the Notes pursuant to this Section 7.10 shall be accompanied by a certificate, executed by a Responsible Officer of the Company and dated the date of such offer, specifying: (i) the Proposed Prepayment Date; (ii) that such offer is made pursuant to this Section 7.10; (iii) the principal amount of each Note offered to be prepaid; (iv) the interest that would be due on each Note offered to be prepaid, accrued to the Proposed Prepayment Date; (v) that the conditions of this Section 7.10 have been fulfilled; and (vi) in reasonable detail, the nature and date of the Change of Control. 22 Section 7.11. Payments. The Company will make each payment which it owes under the Transaction Documents to the Person to whom such payment is owed, in lawful money of the United States of America, without set-off, deduction or counterclaim, and in immediately available funds. Each such payment must be received by such Person not later than 12:00 noon, Houston, Texas time, on the date such payment becomes due and payable in accordance with the instructions contained on Schedule A hereto. Any payment received by such Person after such time will be deemed to have been made on the next following Business Day. Anything in this Agreement or the Notes to the contrary notwithstanding, any payment of principal, Make-Whole Amount or interest on any Note that is due on a date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day. Section 7.12. Increased Costs. (a) Eurodollar Changes in Law. If any Change in Law shall: (i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Holder of a Floating Rate Note (except any such reserve requirement reflected in the Adjusted LIBO Rate); or (ii) impose on any Holder of a Floating Rate Note or the London interbank market any other condition affecting this Agreement or Floating Rate Notes held by such Holder; and the result of any of the foregoing shall be to increase the cost to such Holder of making or maintaining any Floating Rate Note or to reduce the amount of any sum received or receivable by such Holder (whether of principal, interest or otherwise), then the Company will pay to such Holder such additional amount or amounts as will compensate such Holder for such additional costs incurred or reduction suffered. (b) Certificates. A certificate of a Holder setting forth the amount or amounts necessary to compensate such Holder as specified in Section 7.12(a) shall be delivered to the Company and shall be conclusive absent manifest error. The Company shall pay such Holder the amount shown as due on any such certificate within 10 days after receipt thereof. (c) Effect of Failure or Delay in Requesting Compensation. Failure or delay on the part of any Holder to demand compensation pursuant to this Section 7.12 shall not constitute a waiver of such Holder's right to demand such compensation. Section 7.13. Break Funding Payments. In the event of (a) the payment of any principal of any Floating Rate Note other than on the last day of an Interest Period applicable thereto (including as a result of a Change of Control or an Event of Default), (b) the substitution of the Alternate Base Rate for the Adjusted LIBO Rate pursuant to Section 7.1(b) other than on the last day of the Interest Period applicable thereto, or (c) the failure to prepay any Floating Rate Note on the date specified in any notice delivered pursuant hereto, then, in any such event, the Company shall compensate each Holder of a Floating Rate Note for the loss, cost and expense attributable to such event. In the case of a Floating Rate Note, such loss, cost or expense to any 23 Holder of a Floating Rate Note shall be deemed to include an amount determined by such Holder to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Floating Rate Note had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Floating Rate Note, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Floating Rate Note), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Holder would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. A certificate of any Holder of a Floating Rate Note setting forth any amount or amounts that such Holder is entitled to receive pursuant to this Section 7.13 shall be delivered to the Company and shall be conclusive absent manifest error. The Company shall pay such Holder the amount shown as due on any such certificate within 10 days after receipt thereof. Section 7.14. Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Holder of a Floating Rate Note or its applicable lending office to honor its obligation to make or maintain Floating Rate Notes either generally or having a particular Interest Period hereunder, then such Holder shall promptly notify the Company and the Collateral Agent thereof and interest on such Floating Rate Notes shall accrue at the Alternate Base Rate plus the Applicable Margin until such time as such Holder may again make or maintain such Floating Rate Notes.

Section 8.3. Title Information. (a) On or before the delivery to the Collateral Agent and the Purchasers of each Engineering Report required by Section 8.1(c), the Company will deliver title information in form and substance acceptable to the Collateral Agent covering enough of the Oil and Gas Properties evaluated by such Engineering Report that were not included in the immediately preceding Engineering Report, so that the Collateral Agent shall have received together with title information previously delivered to the Collateral Agent, satisfactory title information on at least 80% of the total value of the Proved Reserves of the Oil and Gas Properties evaluated by such Engineering Report. (b) If the Company has provided title information for additional Oil and Gas Properties under Section 8.3(a), the Company shall, within 60 days of notice from the Collateral Agent that title defects or exceptions exist with respect to such additional Oil and Gas Properties, either (i) cure any such title defects or exceptions (including defects or exceptions as to priority) which are not Permitted Liens raised by such information, (ii) substitute acceptable Mortgaged Properties with no title defects or exceptions except for Permitted Liens (other than Permitted Liens described in clauses (f) of such definition) having an equivalent value or (iii) deliver title information in form and substance acceptable to the Collateral Agent so that the Collateral Agent shall have received, together with title information previously delivered to the Collateral Agent, satisfactory title information on at least 80% of the value of the Proved Reserves of the Oil and Gas Properties evaluated by such Engineering Report. (c) If the Company is unable to cure any title defect requested by the Collateral Agent or the Purchasers to be cured within the 60-day period or the Company does not comply with the requirements to provide acceptable title information covering 80% of the value of the Proved Reserves of the Oil and Gas Properties evaluated in the most recent Engineering Report, then the Collateral Agent and/or the Majority Purchasers shall have the right to exercise the following remedy in their sole discretion from time to time, and any failure to so exercise this remedy at any time shall not be a waiver as to future exercise of the remedy by the Collateral Agent or the Purchasers. To the extent that the Collateral Agent or the Majority Purchasers are not satisfied with title to any Mortgaged Property after the 60-day period has elapsed, such 36 unacceptable Mortgaged Property shall not count towards the 80% requirement, and the Collateral Agent may send a notice to the Company and the Purchasers that the then outstanding Adjusted Total NPV shall be reduced by an amount as determined by the Majority Purchasers. This new Adjusted Total NPV shall become effective immediately after receipt of such notice. Section 8.4. Further Assurances.

The Company also agrees to deliver, whenever requested by the Collateral Agent or any Purchaser in its sole and absolute discretion, favorable title opinions from legal counsel acceptable to the Collateral Agent and such Purchaser with respect to Properties designated by the Collateral Agent or such Purchaser, based upon abstract or record examinations to dates acceptable to the Collateral Agent and such Purchaser, which opinions shall (i) state that the Company or its Subsidiaries, as applicable, has good and defensible title thereto, subject only to Permitted Liens of the types described in clauses (a) to (e) and (g) of the definition thereof, (ii) confirm that such Properties and interests are subject to Security Documents securing the Notes that constitute and create legal, valid and duly perfected deed of trust or mortgage Liens in such Properties and interests and assignments of and security interests in the oil and gas attributable thereto and in the proceeds thereof, subject, in each case, to no prior Liens other than Permitted Liens of the types described in clauses (a) to (e) and (g) of the definition thereof, and (iii) cover such other matters as the Collateral Agent or such Purchaser may request. (b) The Company hereby authorizes the Collateral Agent to file one or more financing or continuation statements, and amendments thereto, relative to all or any part of the Company's or any Subsidiary's Property without the signature of the Company, such Subsidiary or any other Person.

Upon the occurrence of a Default, the Collateral Agent may (subject to ARTICLE XVI) exercise all rights and remedies granted under the Security Documents, including the right to obtain possession of all Production Proceeds then held by the Company or any of its Subsidiaries and to receive directly from the purchasers of production all other Production Proceeds. In no case shall any failure, whether purposed or inadvertent, by the Collateral Agent to collect directly any such Production Proceeds constitute in any way a waiver, remission or release of any of its rights under the Security Documents, nor shall any release of any Production Proceeds by the Collateral Agent to the Company or any of its Subsidiaries constitute a waiver, remission, or release of any other Production Proceeds or of any rights of the Collateral Agent to collect other Production Proceeds thereafter.

(iii) Without limitation of any other provision of this Section 9.1(q), the Adjusted Total NPV shall be redetermined semi-annually in accordance with this Section 9.1(q) on April 30th and October 31st of each year, commencing October 31, 2003 (a "Scheduled Redetermination"). In addition, the Company may, by notifying the Collateral Agent thereof, and the Collateral Agent may, at the direction of the Majority Purchasers, by notifying the Company thereof, one time during any 12-month period, each elect to cause the Adjusted Total NPV to be redetermined between Scheduled Redeterminations (an "Interim Redetermination") in accordance with this Section 9.1(q). Each Scheduled Redetermination and each Interim Redetermination shall be effectuated as follows: Upon receipt by the Collateral Agent of (A) the Engineering Report and the certificate required to be delivered by the Company to the Collateral Agent and the Purchasers, in the case of a Scheduled Redetermination, pursuant to Section 8.1(c)(i), and, in the case of an Interim Redetermination, pursuant to Section 8.1(c)(ii), and (B) such other reports, data and supplemental information, including, without limitation, the information provided pursuant to Section 8.1(c)(iii), as may, from time to time, be requested by the Collateral Agent (the Engineering Report, such certificate and such other reports, data and supplemental information being the "Reports"), the Collateral Agent shall evaluate the information contained in the Reports and shall, in good faith, calculate a proposed Adjusted Total NPV (the "Proposed Adjusted Total NPV") based upon the Total NPV and such other information (including, without limitation, the status of title information with respect to the Oil and Gas Properties as described in the Reports) as the Collateral Agent deems appropriate and consistent with its normal oil and gas lending criteria as it exists at the particular time. (iv) The Collateral Agent shall notify the Company and the Purchasers of the Proposed Adjusted Total NPV (the "Proposed Adjusted Total NPV Notice"): (A) in the case of a Scheduled Redetermination (1) if the Collateral Agent shall have received the Reports required to be delivered by the Collateral Agent pursuant to Section 8.1(c)(i) in a timely and complete manner, then on or before the April 15th 44 and October 15th of such year following the date of delivery or (2) if the Collateral Agent shall not have received the Reports required to be delivered by the Company pursuant to Section 8.1(c)(i) in a timely and complete manner, then promptly after the Collateral Agent has received complete Reports from the Company and has had a reasonable opportunity to determine the Proposed Adjusted Total NPV in accordance with Section 9.1(q)(iii); and (B) in the case of an Interim Redetermination, promptly, and in any event, within fifteen (15) days after the Collateral Agent has received the required Reports. (v) Any Proposed Adjusted Total NPV that would increase the Adjusted Total NPV then in effect must be approved or deemed to have been approved by all of the Purchasers as provided in this Section 9.1(q)(v); and any Proposed Adjusted Total NPV that would decrease or maintain the Adjusted Total NPV then in effect must be approved or be deemed to have been approved by the Super-majority Purchasers as provided in this Section 9.1(q)(v). Upon receipt of the Proposed Adjusted Total NPV Notice, each Purchaser shall have fifteen (15) days to agree with the Proposed Adjusted Total NPV or disagree with the Proposed Adjusted Total NPV by proposing an alternate Adjusted Total NPV. If at the end of such fifteen (15) days, any Purchaser has not communicated its approval or disapproval in writing to the Collateral Agent, such silence shall be deemed to be an approval of the Proposed Adjusted Total NPV. If, at the end of such 15-day period, all of the Purchasers, in the case of a Proposed Adjusted Total NPV that would increase the Adjusted Total NPV then in effect, or the Super-majority Purchasers, in the case of a Proposed Adjusted Total NPV that would decrease or maintain the Adjusted Total NPV then in effect, have approved or deemed to have approved, as aforesaid, then the Proposed Adjusted Total NPV shall become the new Adjusted Total NPV, effective on the date specified in Section 9.1(q)(vi). If, however, at the end of such 15-day period, all of the Purchasers or the Super-majority Purchasers, as applicable, have not approved or deemed to have approved, as aforesaid, then the Collateral Agent shall poll the Purchasers to ascertain the highest Adjusted Total NPV then acceptable to a number of Purchasers sufficient to constitute the Super-majority Purchasers, for purposes of this Section 9.1(q)(v) and, so long as such amount does not increase the Adjusted Total NPV then in effect, such amount shall become the new Adjusted Total NPV, effective on the date specified in Section 9.1(q)(vi). (vi) After a redetermined Adjusted Total NPV is approved or is deemed to have been approved by all of the Purchasers or the Super-majority Purchasers, as applicable, pursuant to Section 9.1(q)(v), the Collateral Agent shall notify the Company and the Purchasers of the amount of the redetermined Adjusted Total NPV (the "New Adjusted Total NPV Notice"), and such amount shall become the new Adjusted Total NPV, effective and applicable to the Company, the Collateral Agent and the Purchasers: (A) in the case of a Scheduled Redetermination, (1) if the Collateral Agent shall have received the Reports required to be delivered by the Company pursuant to Section 8.1(c)(i) in a timely and complete manner, then on the April 30th or October 31st, as applicable, following such notice, or (2) if the Collateral Agent shall not have received the Reports required to be delivered by the Company pursuant to Section 8.1(c)(ii) in a timely and complete manner, then on the Business Day next succeeding delivery of such notice; and 45 (B) in the case of an Interim Redetermination, on the Business Day next succeeding delivery of such notice. Such Adjusted Total NPV shall then become the Adjusted Total NPV until the next Scheduled Redetermination Date, the next Interim Redetermination Date or the next adjustment to the Adjusted Total NPV under Section 8.3(c) or Section 9.1(h)(iv), whichever occurs first. (r) EBITDAX to Fixed Charges Ratio. The Company will not, as of the last day of any Fiscal Quarter, permit its ratio of EBITDAX for the four Fiscal Quarter period ending on such day to the Company's Consolidated Fixed Charges for the same four Fiscal Quarter period, to be less than 1.25 to 1.0. If the Company or any of its Subsidiaries has merged with or acquired any Person during such four Fiscal Quarter Period, the Company's EBITDAX and Consolidated Fixed Charges for such period shall be calculated after giving pro forma effect to such merger or acquisition, as if such merger or acquisition had occurred on the first day of the Fiscal Quarter in which it actually occurred. (s) Current Ratio. The Company will not permit, as of the last day of any Fiscal Quarter, its ratio of (i) Consolidated current assets (including the unused amount of the total commitments under the Bank Credit Agreement, but excluding (A) non-cash assets under FAS 133 and (B) accounts receivable or other rights to payment arising from: (x) the sale of gas production, unless the same are due and payable (and reasonably expected by the Company to be paid) within sixty (60) days after the month in which gas is produced; (y) the sale of oil production, unless the same are due and payable (and reasonably expected by the Company to be paid) within thirty (30) days after the month in which such oil is produced; and (z) Excluded Accounts) to (ii) Consolidated current liabilities (excluding non-cash obligations under FAS 133 and FAS 143) to be less than 1.0 to 1.0.

Section 10.2. Acceleration. (a) If an Event of Default with respect to the Company or any of its Subsidiaries described in Section 10.1(j) or Section 10.1(k) has occurred, all the Notes then outstanding shall automatically become immediately due and payable. (b) If any other Event of Default (including, without limitation, any Event of Default described in Section 10.1(a) or Section 10.1(b)) has occurred and is continuing, any Holder or Holders of more than 50% in principal amount of the Notes at the time outstanding may at any time at its or their option, by written notice or notices to the Company, declare all the Notes then outstanding to be immediately due and payable. 48 (c) If any Event of Default described in Section 10.1(a) or Section 10.1(b) has occurred and is continuing, any Holder affected by such Event of Default may at any time, at its option, by written notice to the Company, declare all the Notes held by it to be immediately due and payable.

The Company shall keep at its principal executive office a register for the registration and registration of transfers of Notes. The name and address of each Holder, each transfer thereof and the name and address of each transferee of one or more Notes shall be registered in such register. Prior to due presentment for registration of transfer, the Person in whose name any Notes shall be registered shall be deemed and treated as the owner and Holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary. The Company shall give to any Holder that is an Institutional Investor promptly upon request therefor, a complete and correct copy of the names and addresses of all registered Holders of Notes. Section 11.2. Transfer and Exchange of Notes. Upon surrender of any Notes at the principal executive office of the Company for registration of transfer or exchange (and in the case of a surrender for registration of transfer, duly endorsed or accompanied by a written instrument of transfer duly executed by the registered Holder of such Notes or its attorney duly authorized in writing and accompanied by the address for notices of each transferee of such Notes or part thereof), the Company shall execute and deliver, at the Company's expense (except as provided below), one or more new Notes (as requested by the Holder thereof) in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of the surrendered Notes. Each such new Note shall be payable to such Person as such Holder may request and shall be substantially in the form of Exhibit 1 or Exhibit 2, as applicable. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the surrendered Notes or dated the date of the surrendered Notes if no interest shall have been paid thereon. The Company may require payment of a sum sufficient to cover any stamp tax or governmental charge imposed in respect of any such transfer of Notes. Notes shall not be transferred in amounts of less than $100,000, provided that if necessary to enable the registration of transfer by a Holder of its entire holding of Notes, one Note may be in a denomination of less than $100,000. Any transferee, by its acceptance of a Note registered in its name (or the name of its nominee), shall be deemed to have made the representations set forth in ARTICLE VI. Section 11.3.

ARTICLE XII. COLLATERAL AGENT Section 12.1. Appointment and Authority. Each Purchaser hereby appoints BNP Paribas as collateral agent (in such capacity, together with its successors and assigns in such capacity, the "Collateral Agent") under the Transaction Documents, to exercise such powers under the Transaction Documents as are delegated to the Collateral Agent by the terms thereof, together with all such powers as are reasonably incidental thereto, including taking, holding and disposing of the Collateral. BNP Paribas hereby accepts such appointment. The Collateral Agent shall act for and on behalf of the Purchasers in connection with all Collateral and all Security Documents, including serving as mortgagee under each Mortgage and exercising rights and remedies provided thereunder. The Collateral Agent is hereby authorized to release Collateral to consummate any transaction permitted by Section 9.1(h) or if the Collateral Agent has otherwise received the prior consent of all of the Purchasers, it being understood that no Purchaser itself need be a party to any such release. In its administration of this Agreement and the other Transaction Documents, the Collateral Agent will exercise the same care that a commercial bank would exercise in the administration or handling of transactions for its own account. The relationship of the Collateral Agent to the Purchasers is only that of one investor acting to hold collateral on behalf of itself and others as a convenience to all, and nothing in the Transaction Documents shall be construed to constitute the Collateral Agent a trustee or other fiduciary for any Holder or of any participation therein nor to impose on the Collateral Agent any duties and obligations other than those expressly provided for in the Transaction Documents. With respect to any matters not expressly provided for in the Transaction Documents and any matters which the Transaction Documents place within the discretion of the Collateral Agent, the Collateral Agent shall not be required to exercise any discretion or take any action, and it may request instructions from the Purchasers with respect to any such matter, in which case it shall be required to act or to refrain from acting (and shall be fully protected and free from liability to all Purchasers in so acting or refraining from acting) upon the instructions of the Majority Purchasers, provided, however, that the Collateral Agent shall not be required to take any action which exposes it to a risk of personal liability that it considers unreasonable or which is contrary to the Transaction Documents or to applicable law and provided further, and notwithstanding anything to the contrary in this Agreement or in any other Transaction Document, the Collateral Agent shall be under no obligation to exercise any of the rights or powers vested in it by this Agreement or any other Transaction Document at the request or direction of any Purchaser unless the Purchasers shall have furnished to the Collateral Agent security or indemnity to the satisfaction of the Collateral Agent against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. Section 12.2. Exculpation, Collateral Agent's Reliance, Etc. Neither the Collateral Agent nor any Related Party shall be liable for any action taken or omitted to be taken by any of them under or in connection with the Transaction Documents, INCLUDING THEIR NEGLIGENCE OF ANY KIND, except that each shall be liable for its own gross negligence or 51 willful misconduct. Without limiting the generality of the foregoing, the Collateral Agent (a) may treat the registered Holder of any Note as the Holder thereof until the Collateral Agent receives written notice of the assignment or transfer thereof in accordance with this Agreement; (b) may consult with legal counsel (including counsel for the Company), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any Purchaser and shall not be responsible to any Purchaser for any statements, warranties or representations made in or in connection with the Transaction Documents; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of the Transaction Documents on the part of the Company or any Subsidiary of the Company or to inspect the Property (including the books and records) of the Company or any Subsidiary of the Company or to forward notices to the Purchasers on behalf of the Company or any of its Subsidiaries; (e) shall not be responsible to any Purchaser for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of any Transaction Document or any instrument or document furnished in connection therewith; (f) may rely upon the representations and warranties of each of the Company and each Subsidiary of the Company and the Purchasers in exercising its powers hereunder; and (g) shall incur no liability under or in respect of the Transaction Documents by acting upon any notice, consent, certificate or other instrument or writing (including any telecopy, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper Person or Persons. Section 12.3. Credit Decisions. Each Purchaser acknowledges that it has, independently and without reliance upon any other Purchaser or the Collateral Agent, made its own analysis of the Company and the transactions contemplated hereby and its own independent decision to enter into this Agreement and the other Transaction Documents, Each Purchaser also acknowledges that it will, independently and without reliance upon any other Purchaser or the Collateral Agent and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Transaction Documents. Each Purchaser acknowledges that Vinson & Elkins L.L.P. is acting in this transaction as special counsel to the Collateral Agent and the Purchasers. Notwithstanding the foregoing, and that from time to time the interests of the Collateral Agent and the Purchasers may be aligned, the Collateral Agent and the Purchasers understand, acknowledge and agree that their interests may from time to time conflict, and to the extent of any conflict, Vinson & Elkins L.L.P. shall be acting solely and exclusively as counsel for the Collateral Agent under such circumstances. The Purchasers and the Collateral Agent hereby waive any conflict created by the foregoing arrangement in connection with the Transaction Documents and the transactions contemplated thereby to the fullest extent permitted by applicable law. Section 12.4. Rights as Purchaser. In its capacity as a Purchaser, the Collateral Agent and each Affiliate of the Collateral Agent shall have the same rights and obligations as any Purchaser and may exercise such rights as though it were not the Collateral Agent or an Affiliate of the Collateral Agent. The Collateral Agent and its Affiliates may generally engage in any kind of business with the Company or any Subsidiary or Affiliate of the Company, all as if it were not the Collateral Agent hereunder and without any duty to account therefor to any Purchaser. 52 Section 12.5. Sharing of Set-Offs, Collections, and Payments. (a) Each Purchaser agrees that if it shall, whether through the exercise of rights under Security Documents or rights of banker's lien, set off, or counterclaim against the Company or otherwise, obtain payment of a portion of the aggregate Obligations owed to it which, taking into account all distributions made by the Collateral Agent under this Agreement, causes such Purchaser to have received more than it would have received had such payment been made pro rata to each Purchaser in accordance with Section 12.5(b), then (i) it shall be deemed to have simultaneously purchased and shall be obligated to purchase interests in the Obligations as necessary to cause all Purchasers to share all payments as if such payments had been made pro rata to each Purchaser in accordance with Section 12.5(b), and (ii) such other adjustments shall be made from time to time as shall be equitable to ensure that the Collateral Agent and all Purchasers share all payments of Obligations as if such payments had been made pro rata to each Purchaser in accordance with Section 12.5(b); provided, however, that nothing herein contained shall in any way affect the right of any Purchaser to obtain payment (whether by exercise of rights of banker's lien, set-off or counterclaim or otherwise) of Liabilities other than the Obligations, including, without limitation, any payment in respect of Debt under the Bank Credit Agreement, any other Bank Document or any Hedging Contract, and no obligation shall exist on the part of any Purchaser to share any payments received in respect thereof. The Company expressly consents to the foregoing arrangements and agrees that any holder of any such interest or other participation in the Obligations, whether or not acquired pursuant to the foregoing arrangements, may to the fullest extent permitted by law exercise any and all rights of banker's lien, set-off, or counterclaim as fully as if such holder were a holder of the Obligations in the amount of such interest or other participation. If all or any part of any funds transferred pursuant to this Section 12.5(a) is thereafter recovered from the seller under this Section 12.5(a) which received the same, the purchase provided for in this Section 12.5(a) shall be deemed to have been rescinded to the extent of such recovery, together with interest, if any, if interest is required pursuant to an order of a Governmental Authority to be paid on account of the possession of such funds prior to such recovery. (b) All proceeds realized from the liquidation or other disposition of Collateral or otherwise received after maturity of the Notes, whether by acceleration or otherwise, shall be applied as follows: (i) first, to reimbursement of expenses and indemnities owing by the Company, any Guarantor or any Subsidiary provided for in this Agreement and the other Transaction Documents to the Collateral Agent; (ii) second, pro rata to reimbursement of expenses and indemnities owing by the Company, any Guarantor or any Subsidiary provided for in this Agreement and the other Transaction Documents to the Purchasers; (iii) third, pro rata to Make-Whole Amounts on the Fixed Rate Notes; (iv) fourth, pro rata to accrued interest on the Notes; (v) fifth, pro rata to fees; 53 (vi) sixth, pro rata to principal outstanding on the Notes; (vii) seventh, pro rata to any other Obligations; and (viii) eighth, to the Company or as otherwise required by any Governmental Requirement. Section 12.6. Investments. Whenever the Collateral Agent in good faith determines that it is uncertain about how to distribute to Purchasers any funds which it has received, or whenever the Collateral Agent in good faith determines that there is any dispute among Purchasers about how such funds should be distributed, the Collateral Agent may choose to defer distribution of the funds which are the subject of such uncertainty or dispute. If the Collateral Agent in good faith believes that the uncertainty or dispute will not be promptly resolved, or if the Collateral Agent is otherwise required to invest funds pending distribution to Purchasers, the Collateral Agent shall invest such funds pending distribution in one or more separate accounts not commingled with other assets of the Collateral Agent; all interest on any such investment shall be distributed upon the distribution of such investment and in the same proportion and to the same Persons as such investment. All moneys received by the Collateral Agent for distribution to Purchasers (other than to a Person who is the Collateral Agent in its separate capacity as a Purchaser) shall be held by the Collateral Agent pending such distribution solely as the Collateral Agent for such Purchasers, and the Collateral Agent shall have no equitable title to any portion thereof. Section 12.7. Benefit of Article XII. The provisions of this Article are intended solely for the benefit of Purchasers and the Collateral Agent, and neither the Company nor any Subsidiary of the Company shall be entitled to rely on any such provision or assert any such provision in a claim or defense against any Purchaser or the Collateral Agent. Purchasers and the Collateral Agent may waive or amend such provisions as they desire without any notice to or consent of the Company or any Subsidiary of the Company. Section 12.8. Resignation. The Collateral Agent may resign at any time by giving written notice thereof to the Purchasers and the Company. Each such notice shall set forth the date of such resignation. Upon any such resignation the Majority Purchasers shall designate a successor Collateral Agent. A successor must be appointed for any retiring Collateral Agent, and such Collateral Agent's resignation shall become effective when such successor accepts such appointment. If, within thirty days after the date of the retiring Collateral Agent's resignation, no successor Collateral Agent has been appointed and has accepted such appointment, then the retiring Collateral Agent may appoint a successor Collateral Agent. Upon the acceptance of any appointment as the Collateral Agent hereunder by a successor Collateral Agent, the retiring Collateral Agent shall be discharged from its duties and obligations under this Agreement and the other Transaction Documents. After any retiring Collateral Agent's resignation hereunder the provisions of this ARTICLE XII and ARTICLE XIV shall continue to inure to its benefit as to any actions taken or omitted to be taken by it while it was the Collateral Agent under the Transaction Documents. The Company hereby agrees to pay all fees, if any, as may be charged by any successor Collateral Agent that is a national or state bank or trust company which such Person may reasonably charge for its services as the Collateral Agent, and to enter into or 54 consent to such documents and instruments as such successor Collateral Agent may request in connection with its service and appointment as Collateral Agent. ARTICLE XIII. PAYMENTS ON NOTES Section 13.1. Place of Payment.

Subject to Section 13.2, each Holder may change the place of payment of the Notes by giving written notice to BNP Paribas and the Company long as such place of payment shall be in New York. Section 13.2. Home Office Payment. So long as any Purchaser originally party hereto, or any nominee of such Purchaser, shall be the Holder of any Note, and notwithstanding anything contained in Section 13.1 or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal, Make-Whole Amount and interest by the method and at the address specified for such purpose below such Purchaser's name in Schedule A, or by such other method or at such other address as such Purchaser shall have from time to time specified to the Company in writing for such purpose, without the presentation or surrender of such Note or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably promptly after payment or prepayment in full of any Note, such Purchaser shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently designated by the Company pursuant to Section 13.1. Prior to any sale or other disposition of any Note held by such Purchaser or such Purchaser's nominee, such Purchaser will, at such Purchaser's election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes pursuant to Section 11.2. The Company will afford the benefits of this Section to any Institutional Investor that is the direct or indirect transferee of any Note purchased by such Purchaser under this Agreement and that has made the same agreement relating to such Note as such Purchaser has made in this Section.

(b) To the extent permitted by applicable law, the Company shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Transaction Document or any 57 agreement or instrument contemplated hereby or thereby, the transactions contemplated thereby, the Notes or the use of the proceeds thereof. Section 14.3. Payment of Expenses and Indemnity. All amounts due under this ARTICLE XIV shall be payable promptly after written demand therefor. ARTICLE XV. AMENDMENT AND WAIVER Section 15.1. Amendment and Waiver. (a) Neither this Agreement nor any provision hereof nor any other Transaction Document nor any provision thereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Company and the Majority Purchasers or by the Company and the Collateral Agent with the consent of the Majority Purchasers; provided that no such agreement shall (i) reduce the principal amount of, or the Make-Whole Amount on, any Note or reduce the rate of, or change the method of computation of, interest or the Make-Whole Amount thereon, or reduce any fees payable hereunder, or reduce any other Obligations hereunder or under any other Transaction Document, without the written consent of each Purchaser affected thereby, (ii) subject to the provisions of ARTICLE X relating to acceleration or rescission, postpone the scheduled date or time of any payment or prepayment of the principal amount of, or the Make-Whole Amount on, any Note, or any interest thereon, or any fees payable hereunder, or any other Obligations hereunder or under any other Transaction Document, or reduce the amount of, waive or excuse any such payment or prepayment, or postpone or extend the maturity date without the written consent of each Purchaser affected thereby, (iii) waive or amend Section 1.1, ARTICLE II, ARTICLE IV, ARTICLE VI, ARTICLE VII or Section 12.1 (or any defined term as it is used therein), without the written consent of each Purchaser, (iv) change Section 12.5 in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Purchaser, (v) waive or amend Section 8.2 or Section 8.3 or change the definition of the terms "Domestic Subsidiary", "Foreign Subsidiary" or "Subsidiary", without the written consent of each Purchaser, (vi) release any Guarantor (except as set forth in this Agreement or in a Guaranty Agreement), release any of the Collateral (other than as provided in Section 12.1), or reduce the percentage set forth in Section 8.2(a) to less than 80%, without the written consent of each Purchaser, (vii) waive or amend ARTICLE XVI, or the definitions used in ARTICLE XVI, which would have the effect of accelerating the date for, or increasing the amount of, any scheduled prepayment of principal of the Notes, or which would have the effect of modifying ARTICLE XVI, or the definitions used in ARTICLE XVI, without the written consent of each Purchaser and the Senior Indebtedness Representative or (viii) change any of the provisions of this Section 15.1(a) or the definitions of "Purchaser", "Majority Purchasers" or "Super-majority Purchasers" or any other provision hereof specifying the number or percentage of Purchasers required to waive, amend or modify any rights hereunder or under any other Transaction Documents or make any determination or grant any consent hereunder or any other Transaction Documents, without the written consent of each Purchaser; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Collateral Agent hereunder or under any other Transaction Document without the prior written consent of the Collateral Agent. Notwithstanding the foregoing, any supplement to the Disclosure Schedule related to Section 5.1(l) shall be effective simply by delivering to the 58 Collateral Agent a supplemental schedule clearly marked as such and, upon receipt, the Collateral will promptly deliver a copy thereof to the Purchasers. (b) No failure on the part of the Collateral Agent or any Purchaser to exercise and no delay in exercising, and no course of dealing with respect to, any right, power or privilege, or any abandonment or discontinuance of steps to enforce such right, power or privilege, under any of the Transaction Documents shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege under any of the Transaction Documents preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies of the Collateral Agent and the Purchasers hereunder and under the other Transaction Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or any other Transaction Document or consent to any departure by the Company therefrom shall in any event be effective unless the same shall be permitted by Section 15.1(a), and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the purchase of a Note shall not be construed as a waiver of any Default, regardless of whether the Collateral Agent or any Purchaser may have had notice or knowledge of such Default at the time. Section 15.2. Binding Effect; Etc. Any amendment or waiver consented to as provided in Section 15.1(a) applies equally to all Holders and is binding upon them and upon each future Holder and upon the Company without regard to whether such Note has been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Company and any Holder nor any delay in exercising any rights hereunder or under any Note shall operate as a waiver of any rights of any Holder of such Note. Section 15.3. Solicitation of Holders of Notes. (a) Solicitation. The Company will provide each Purchaser (irrespective of the amount of Notes then owned by it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such Purchaser to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof or of the Transaction Documents. The Company will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of Section 15.1(a) to each Purchaser promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite Purchasers. (b) Payment. The Company will not directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security, guaranty or other form of credit support or credit enhancement, to any Purchaser as consideration for or as an inducement to the entering into by any Purchaser of any waiver or amendment of any of the terms and provisions hereof unless such remuneration is concurrently paid, or security, guaranty or other form of credit support or credit enhancement is concurrently granted, on the same terms, ratably to or for the benefit of each Purchaser then outstanding even if such Purchaser did not consent to such waiver or amendment. 59 Section 15.4. Notes Held by Company. Solely for the purpose of determining whether the Holders of the requisite percentage of the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent to be given under this Agreement or the Notes, or have directed the taking of any action provided herein or in the Notes to be taken upon the direction of the Holders of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or indirectly owned by the Company or any of its Affiliates shall be deemed not to be outstanding. ARTICLE XVI. SUBORDINATION OF THE NOTES Section 16.1. Subordination of Obligations. The Company and each Subsidiary of the Company covenant and agree, and each Holder by its acceptance of a Note covenants and agrees, that the payment of the Subordinated Obligations shall, to the extent set forth in this ARTICLE XVI, be subordinate and junior and subject in right of payment to the prior payment in full in cash of all Senior Indebtedness, whether outstanding on the date hereof or hereafter created, incurred, assumed or guaranteed. Section 16.2. Payment Default or Acceleration. Except under circumstances when the terms of Section 16.5 are applicable, if (a) a Payment Default or Senior Indebtedness Acceleration shall have occurred and be continuing and (b) the Holders or their collateral agent or other representative shall have received a Payment Default Notice, then the Company and any Subsidiary of the Company may not make, and no Holder shall accept, receive or collect, any direct or indirect payment or distribution of any kind or character (in cash, securities, other Property, by setoff, or otherwise other than Reorganization Securities) of any properties or assets of the Company or any Subsidiary of the Company on account of the Subordinated Obligations during the Payment Blockage Period; provided, however, that in the case of any payment on or in respect of any Subordinated Obligation that would (in the absence of any such Payment Default Notice) have been due and payable on any date (a "Scheduled Payment Date") during such Payment Blockage Period pursuant to the terms of the Notes as in effect on the date hereof or as amended consistent with the provisions of Section 16.12, the provisions of this Section 16.2 shall not prevent the making and acceptance of such payment (a "Scheduled Payment"), together with any additional default interest as is due on the Notes, on or after the date immediately following the termination of such Payment Blockage Period. In the event that, notwithstanding the foregoing, the Company or any Subsidiary of the Company shall make any payment or distribution to any Holder prohibited by the foregoing provisions of this Section 16.2, then and in such event such payment or distribution shall be held in trust for the benefit of and immediately shall be paid over to the holders of the Senior Indebtedness or the Senior Indebtedness Representative for application against the Senior Indebtedness remaining unpaid until such Senior Indebtedness are paid in full in cash. Any Payment Default Notice shall be deemed received by the Holders upon the date of actual receipt by the Holders or their collateral agent or other representative of such Payment Default Notice in writing. Section 16.3. Non-Payment Default. Except under circumstances when the terms of Section 16.2 or Section 16.5 are applicable, if (a) a Non-Payment Default shall have occurred and be continuing, (b) the Holders or their collateral agent or other representative shall have received a Non-Payment Default Notice, and (c) no Non-Payment Default Notice shall have been 60 given within the 360 day period immediately preceding the giving of such Non-Payment Default Notice, then the Company and any Subsidiary of the Company may not make, and no Holder shall accept, receive or collect, any direct or indirect payment or distribution of any kind or character (in cash, securities, other Property, by setoff, or otherwise other than Reorganization Securities) of any properties or assets of the Company or any Subsidiary of the Company on account of the Subordinated Obligations during the Non-Payment Blockage Period; provided, however, that in the case of any Scheduled Payment on or in respect of any Subordinated Obligation that would (in the absence of any such Non-Payment Default Notice) have been due and payable on any Scheduled Payment Date during such Non-Payment Blockage Period pursuant to the terms of the Notes as in effect on the date hereof or as amended consistent with the requirements of Section 16.12, the provisions of this Section 16.3 shall not prevent the making and acceptance of such Scheduled Payment, together with any additional default interest as is due on the Notes, on or after the date immediately following the termination of such Non-Payment Blockage Period. In the event that, notwithstanding the foregoing, the Company or any Subsidiary of the Company shall make any payment or distribution to any Holder prohibited by the foregoing provisions of this Section 16.3, then and in such event such payment or distribution shall be held in trust for the benefit of and immediately shall be paid over to the holders of the Senior Indebtedness or the Senior Indebtedness Representative for application against the Senior Indebtedness remaining unpaid until such Senior Indebtedness are paid in full in cash. Any Non-Payment Default Notice shall be deemed received by the Holders upon the date of actual receipt by the Holders or their collateral agent or other representative of such Non-Payment Default Notice in writing. Section 16.4. Standstill. At any time that the Holders are not permitted to receive payments on the Subordinated Obligations pursuant to either Section 16.2 or Section 16.3, the Holders and any collateral agent or other representative of the Holders will not commence any Enforcement Action relative to the Company or any Subsidiary of the Company during the Standstill Period. Upon the termination of the Standstill Period, the Holders may exercise all rights or remedies they may have in law or equity; provided, however, that if a Standstill Period terminates pursuant to clause (e) thereof, no Holder and no agent or representative thereof shall exercise any remedies against, or attempt to foreclose upon, garnish, sequester or execute upon, any Property known to it as constituting collateral for the Senior Indebtedness (other than to file or record any judgment liens it may have obtained against such collateral) during the period that such Standstill Period would have been in effect but for termination pursuant to clause (e) of the definition of "Standstill Period;" provided further, that the Payment Blockage Period or the Non-Payment Blockage Period, as the case may be, if not also terminated, shall continue for its full period notwithstanding the termination of the Standstill Period. Notwithstanding the foregoing, no Standstill Period may be commenced while any other Standstill Period exists or within 180 days following the termination of any prior Standstill Period (provided that this sentence shall not relieve any Holder of its obligation to provide notice under Section 16.9). Section 16.5. Insolvency; Bankruptcy; Etc.. In the event of the institution of any Insolvency Proceeding relative to the Company or any Subsidiary of the Company, then: (a) The holders of the Senior Indebtedness shall be entitled to receive payment in full in cash of the Senior Indebtedness before the Holders are entitled to receive any 61 direct or indirect payment or distribution of any kind or character, whether in cash, Property or securities (other than Reorganization Securities) on account of the Subordinated Obligations. (b) Any direct or indirect payment or distribution of any kind or character, whether in cash, Property or securities, by setoff or otherwise, which may be payable or deliverable in such proceedings in respect of the Subordinated Obligations but for the provisions of this ARTICLE XVI shall be paid or delivered by the Person making such payment or distribution, whether the Company, a Subsidiary of the Company, a trustee in bankruptcy, a receiver, a liquidating trustee, or otherwise, directly to the holders of the Senior Indebtedness or the Senior Indebtedness Representative, to the extent necessary to make payment in full in cash of all Senior Indebtedness remaining unpaid; provided, however, that no such delivery of any Reorganization Securities shall be made to holders of the Senior Indebtedness. In the event that, notwithstanding the foregoing provisions of this Section 16.5, the Holders shall have received any such payment or distribution of any kind or character, whether in cash, Property or securities, by setoff or otherwise, before all Senior Indebtedness are paid in full in cash, which is to be paid to the holders of the Senior Indebtedness under the foregoing provisions of this Section 16.5, then and in such event such payment or distribution shall be held in trust for the benefit of and immediately shall be paid over to the holders of the Senior Indebtedness or the Senior Indebtedness Representative for application to the payment of all Senior Indebtedness remaining unpaid until all such Senior Indebtedness shall have been paid in full in cash. (c) If no proof of claim is filed in any Insolvency Proceeding with respect to any Subordinated Obligations by the tenth day prior to the bar date for any such proof of claim, the Senior Indebtedness Representative may, after notice to the Holders or their collateral agent or other representative, file such a proof of claim on behalf of the Holders, and each Holder hereby irrevocably appoints the Senior Indebtedness Representative as its agent and attorney-in-fact for such limited purpose; provided, that the foregoing shall not confer to the holder of any Senior Indebtedness the right to vote on behalf of the Holders in any Insolvency Proceedings. Section 16.6. No Impairment. No right of any present or future holder of Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or any Subsidiary of the Company or by any non-compliance by the Company or any Subsidiary of the Company with the terms, provisions, and covenants of this ARTICLE XVI or the Notes, regardless of any knowledge thereof any such holder may have or be otherwise charged with. The provisions of this ARTICLE XVI shall be enforceable directly by any present or future holder of Senior Indebtedness and/or the Senior Indebtedness Representative. Section 16.7. Rights of Creditors; Subrogation. The provisions of this ARTICLE XVI are for the purpose of defining the relative rights of the holders of Senior Indebtedness on the one hand, and the Holders on the other hand, and nothing herein shall impair, as between the Company and the Holders, the obligation of the Company, which is unconditional and absolute, to pay to the Holders the principal thereof and Make-Whole Amount (in the case of Fixed Rate Notes), if any, and interest thereon in accordance with their terms and the provisions hereof, nor shall anything herein, except as otherwise provided in Section 16.4, prevent the Holders from exercising all remedies otherwise permitted by applicable law or hereunder upon default hereunder or under the Notes (including the right to demand payment and sue for performance 62 hereof and of the Notes and to accelerate the maturity thereof as provided by the terms of the Notes), subject to the rights of holders of Senior Indebtedness under this ARTICLE XVI. Upon payment in full of the Senior Indebtedness in cash and termination of the commitments of any holder of Senior Indebtedness to make loans or extensions of credit, and expiration or termination of all letters of credit issued by any holder of Senior Indebtedness, the Holders shall, to the extent of any payments or distributions paid or delivered to the holders of the Senior Indebtedness or otherwise applied to the Senior Indebtedness pursuant to the provisions of this ARTICLE XVI, be subrogated to the rights of the holders of the Senior Indebtedness to receive payments or distributions of assets of the Company made on Senior Indebtedness (and any security therefor) until the Subordinated Obligations shall be paid in full (and, for this purpose, no such payments or distributions paid or delivered to the holders of the Senior Indebtedness or otherwise applied to the Senior Indebtedness shall be deemed to have discharged the Subordinated Obligations), and, for the purposes of such subrogation, no payments to the holders of Senior Indebtedness of any cash, assets, stock, or obligations to which the Holders would be entitled except for the provisions of this ARTICLE XVI shall, as between the Company, its creditors (other than the holders of the Senior Indebtedness), and the Holders, be deemed to be a payment by the Company to or on account of Senior Indebtedness. The fact that failure to make any payment on account of the Subordinated Obligations is caused by reason of the operation of any provision of this ARTICLE XVI shall not be construed as preventing the occurrence of an Event of Default. Section 16.8. Payments on Senior Indebtedness. In the event that any Holder determines in good faith that evidence is required with respect to the right of any holder of Senior Indebtedness to participate in any payment or distribution pursuant to this ARTICLE XVI or the amount of such participation, such Holder may request such Person to furnish evidence to the reasonable satisfaction of such Holder as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this ARTICLE XVI, and if such evidence is not furnished, such Holder may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment; provided that, upon the written request of such Person to such Holder, such payment shall be made to the court having jurisdiction over such judicial determination or to another Person mutually satisfactory to such Person and such Holder, as escrowee, to be held and invested pending such judicial determination in accordance with such instructions as shall be mutually satisfactory to such Person and such Holder and upon such judicial determination becoming final and nonappealable to be distributed in accordance therewith to the Person entitled thereto. Section 16.9. Notice of Acceleration, Enforcement Action. (a) Each Holder agrees that in the event any Event of Default shall occur, and as a result thereof, any Holder or any collateral agent or other representative of such Holder accelerates maturity of the Notes, then such Holder or collateral agent or other representative shall give prompt (and in any event within 3 Business Days) notice thereof in writing to the holders of the Senior Indebtedness or the Senior Indebtedness Representative. The Company and any Subsidiary of the Company may not pay the Notes until ten Business Days after the Senior Indebtedness Representative receives the notice described above and, after that ten 63 Business Day period, may pay the Notes, and the Holders may receive or collect such payment, only if the provisions of this ARTICLE XVI do not prohibit such payment at that time. (b) Each Holder agrees that in the event any Event of Default shall occur, and as a result thereof, any Holder or any collateral agent or other representative of such Holder intends to commence any Enforcement Action, then such Holder or collateral agent or other representative shall first deliver notice thereof in writing to the Senior Indebtedness Representative both (i) not less than 10 days prior to taking any such Enforcement Action, and (ii) one Business Day after such Enforcement Action is taken.

To the extent any payment of or distribution in respect of the Senior Indebtedness (whether by or on behalf of the Company, as proceeds of security or enforcement of any right of set off or otherwise) is declared to be fraudulent or preferential, set aside or required to be paid to the Company or any Subsidiary of the Company or any receiver, trustee in bankruptcy, liquidating trustee, agent or other similar person under any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then if such payment or distribution is recovered by, or paid over to, the Company or any Subsidiary of the Company or such receiver, trustee in bankruptcy, liquidating trustee, agent or other similar person, the Senior Indebtedness or part thereof originally intended to be satisfied shall be deemed to be reinstated and outstanding as if such payment has not occurred and the provisions of this ARTICLE XVI shall continue to be applicable in respect of said reinstated Senior Indebtedness. Section 16.11. Rights of Holders of Senior Indebtedness. The holders of Senior Indebtedness may, at any time and from time to time subject to the terms of the Senior Indebtedness, without the consent of or notice to the Holders or any collateral agent or other representative of the Holders, without incurring responsibility to the Holders and without impairing or releasing the subordination or other benefits provided in this ARTICLE XVI or the obligations hereunder of the Holders to the holders of Senior Indebtedness, do any one or more of the following: (a) change the manner, place or terms of payment or extend the time of payment of, or renew, increase (but not in excess of the cap provided for in the definition of "Senior Indebtedness"), alter or amend, Senior Indebtedness or any instrument evidencing the same or any covenant or agreement under which Senior Indebtedness is outstanding or secured or any liability of any obligor thereon; (b) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Indebtedness; (c) settle or compromise any Senior Indebtedness or any liability of any obligor thereon or release any Person liable in any manner for the payment of Senior Indebtedness; and (d) waive any default under Senior Indebtedness and exercise or refrain from exercising any rights against the Company, any Subsidiary of the Company or any other Person. The foregoing provisions are not intended to permit a change to the definition of "Senior Indebtedness". Section 16.12. Amendments. No amendment of this ARTICLE XVI, or the definitions used in this ARTICLE XVI, or which would have the effect of modifying this ARTICLE XVI, or the definitions used in this ARTICLE XVI, shall be effective unless it is in writing and made 64 with the prior written consent of the Required Banks or by the Senior Indebtedness Representative on their behalf.

The Holders agree that any notices required to be given to the Holders shall be effective if such notice is given to the collateral agent or other representative of the Holders.

The mortgages included in the Bank Documents do (and other mortgages, security agreements and similar Bank Documents may) describe the indebtedness secured thereby in a manner which might include indebtedness other than the Senior Indebtedness. For so long as any Note is outstanding, as between the Holders and the holders of the Senior Indebtedness, only the Senior Indebtedness shall be deemed to be secured by any Liens granted under the Bank Documents. (b) Each Holder agrees that it will not initiate, join in or prosecute any claim, action or other proceeding challenging the validity or enforceability of the Senior Indebtedness or the Liens securing the Senior Indebtedness. Section 16.15. Legend.

Limitation on Interest. The Purchasers, the Collateral Agent, the Company and any other parties to the Transaction Documents intend to contract in strict compliance with applicable usury law from time to time in effect. In furtherance thereof such Persons stipulate and agree that none of the terms and provisions contained in the Transaction Documents shall ever be construed to create a contract to pay, for the use, forbearance or detention of money, interest in excess of the maximum amount of interest permitted to be charged by applicable law from time to time in effect. Neither the Company nor any present or future guarantors, endorsers, or other Persons hereafter becoming liable for payment of any Obligation shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in excess of the maximum amount that may be lawfully charged under applicable law from time to time in effect, and the provisions of this Section shall control over all other provisions of the Transaction Documents which may be in conflict or apparent conflict herewith. Purchasers and the Collateral Agent expressly disavow any intention to charge or collect excessive unearned interest or finance charges in the event the maturity of any Obligation is accelerated. If (a) the maturity of any Obligation is accelerated for any reason, (b) any Obligation is prepaid and as a result any amounts held to constitute interest are determined to be in excess of the legal maximum, or (c) any Purchaser or any other holder of any or all of the Obligations shall otherwise collect moneys which are determined to constitute interest which would otherwise increase the interest on any or all of the Obligations to an amount in excess of that permitted to be charged by applicable law then in effect, then all such sums determined to constitute interest in excess of such legal limit shall, without penalty, be promptly applied to reduce the then outstanding principal of the related Obligations or, at such Purchaser's or such holder's option, promptly returned to the Company or the other payor thereof upon such determination. In determining whether or not the interest paid or payable, under any specific circumstance, exceeds the maximum amount permitted under applicable law, Purchasers, the Collateral Agent and the Company (and any other payors or payees thereof) shall to the greatest extent permitted under applicable law, (i) characterize any non-principal payment as an expense, fee or premium rather than as interest, (ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the instruments evidencing the Notes in accordance with the amounts outstanding from time to time thereunder and the maximum legal rate of interest from time to time in effect under applicable law in order to lawfully charge the maximum amount of interest permitted under applicable law. Section 17.9. Termination. In its sole and absolute discretion the Company may at any time after all Obligations have been indefeasibly paid in full in cash elect in a notice delivered to all Purchasers to terminate this Agreement and the other Transaction Documents. Upon receipt by Purchasers of such a notice, if no Obligations are then owing then this Agreement and all other Transaction Documents shall thereupon be terminated, the Liens thereunder released, and the parties thereto released from all prospective obligations thereunder. At the request and expense of the Company, Purchasers and the Collateral Agent shall prepare and execute all necessary instruments to reflect and effect such termination of the Transaction Documents. Section 17.10. Reproduction of Documents. This Agreement and all documents relating thereto, including, without limitation, (a) consents, waivers and modifications that may hereafter be executed, (b) documents received by the Collateral Agent or any Purchaser at the Closing (except the Notes themselves), and (c) financial statements, certificates and other information 70 previously or hereafter furnished to the Collateral Agent or such Purchaser, may be reproduced by the Collateral Agent or such Purchaser by any photographic, photostatic, microfilm, microcard, miniature photographic or other similar process and the Collateral Agent or such Purchaser may destroy any original document so reproduced. The Company agrees and stipulates that, to the extent permitted by applicable law, any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by the Collateral Agent or such Purchaser in the regular course of business) and any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. This Section shall not prohibit the Company or the Collateral Agent or any Purchaser from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the in accuracy of any such reproduction. Section 17.11. Confidentiality. For the purposes of this Section, "Confidential Information" means information delivered to any Purchaser by or on behalf of the Company or any Subsidiary of the Company in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received by such Purchaser as being confidential information of the Company or such Subsidiary, provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by such Purchaser or any Person acting on such Purchaser's behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by the Company or any Subsidiary or (d) constitutes financial statements delivered to such Purchaser hereunder that are otherwise publicly available. Such Purchaser will maintain the confidentiality of such Confidential Information in accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to such Purchaser, provided that such Purchaser may deliver or disclose Confidential Information to (i) such Purchaser's directors, officers, employees, agents, attorneys, investors, and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by such Purchaser's Notes), (ii) such Purchaser's Affiliates, auditors, attorneys, and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with the terms of this Section, (iii) any other Purchaser, (iv) any Institutional Investor to which such Purchaser may sell or offer to sell such Note or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section), (v) any Person from which such Purchaser may offer to purchase any security of the Company (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section), (vi) any federal or state regulatory authority having jurisdiction over such Purchaser, (vii) the National Association of Insurance Commissioners or any similar organization, or any nationally recognized rating agency that requires access to information about such Purchaser's investment portfolio or (viii) any other Person to which such delivery or disclosure may be necessary or appropriate (1) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, (2) in response to any subpoena or other legal process, (3) in connection with any litigation to which such Purchaser is a party or (4) if an Event of Default has occurred and is continuing, to the extent such Purchaser may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under such Purchaser's Notes and this Agreement. 71 Each Holder, by its acceptance of such Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any Purchaser of information required to be delivered to such Purchaser under this Agreement or requested by such Purchaser (other than a Purchaser that is a party to this Agreement or its nominee), such Purchaser will enter into an agreement with the Company embodying the provisions of this Section. (References to "Purchaser" in this Section 17.11 also refer to the Collateral Agent.) Notwithstanding anything herein to the contrary, except as reasonably necessary to comply with the securities laws, any Holder (and each employee, representative or other agent of the investors) may disclose to any and all persons, without limitation of any kind, the U.S. federal income tax treatment and tax structure of the offering and all materials of any kind (including opinions and other tax analyses) that are provided to such Holder relating to such tax treatment and tax structure. For this purpose, "tax structure" is limited to facts relevant to the U.S. federal income tax treatment of the offering and does not include information relating to the identity of the issuer, its Affiliates, agents or advisors. Section 17.12. Rules of Construction; Etc. The definitions of terms herein shall apply equally to the singular and plural forms of the terms defined. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. The words "include", "includes" and "including" shall be deemed to be followed by the phrase "without limitation". The word "will" shall be construed to have the same meaning and effect as the word "shall". Unless the context requires otherwise (a) any definition of or reference to any agreement, instrument or other document herein shall be construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth herein), (b) any reference herein to any law shall be construed as referring to such law as amended, modified, codified or reenacted, in whole or in part, and in effect from time to time, (c) any reference herein to any Person shall be construed to include such Person's successors and assigns (subject to the restrictions contained herein), (d) the words "herein", "hereof" and "hereunder", and words of similar import, shall be construed to refer to this Agreement in its entirety and not to any particular provision hereof, (e) with respect to the determination of any time period, the word "from" means "from and including" and the word "to" means "to and including" and (f) any reference herein to Articles, Sections, Exhibits and Schedules shall be construed to refer to Articles and Sections of, Exhibits and Schedules to, this Agreement. No provision of this Agreement or any other Transaction Document shall be interpreted or construed against any Person solely because such Person or its legal representative drafted such provision. Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person. Section 17.13. Severability. Any provision of this Agreement or any other Transaction Document that is prohibited, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition, illegality or 72 unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction.
