The Borrower may prepay the Base Rate Loans upon not less than one Business Day's prior notice to the Administrative Agent (which shall promptly notify the Lenders), which notice shall specify the prepayment date (which shall be a Business Day) and the amount of the prepayment (which shall be at least $1,000,000 or the remaining aggregate principal balance outstanding on the Notes) and shall be irrevocable and effective only upon receipt by the Administrative Agent, provided that interest on the principal prepaid, accrued to the prepayment date, shall be paid on the prepayment date. The Borrower may prepay LIBOR Loans on the same conditions as for Base Rate Loans (except that prior notice to the Administrative Agent shall be not less than three Business Days for LIBOR Loans) and in addition such prepayments of LIBOR Loans shall be subject to the terms of Section 5.05 and shall be in an amount equal to all of the LIBOR Loans for the Interest Period prepaid. (b) Mandatory Prepayments. (i) Termination or Reduction of Aggregate Maximum Credit Amounts. If, after giving effect to any termination or reduction of the Aggregate Maximum Credit Amounts pursuant to Section 2.03(b), the outstanding aggregate principal amount of the Loans plus the LC Exposure exceeds the Aggregate Maximum Credit Amounts, the Borrower shall (i) prepay the Loans on the date of such termination or reduction in an aggregate principal amount equal to the excess, together with interest on the principal amount paid accrued to the date of such prepayment and (ii) if any excess remains after prepaying all of the Loans because of LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to the excess to be held as cash collateral as provided in Section 2.10(b) hereof. (ii) Redetermination of Borrowing Base. Upon any redetermination of the amount of the Borrowing Base in accordance with Section 2.08, if the redetermined Borrowing Base results in a Borrowing Base Deficiency, then the Borrower shall within 30 days after written notice thereof (i) prepay the Loans in an aggregate principal amount sufficient to eliminate such Borrowing Base Deficiency, together with interest on the principal amount paid accrued to the date of each such prepayment, (ii) grant to the Administrative Agent a first priority Lien in additional Properties of the Borrower, which in the Lenders' sole determination, have sufficient value to eliminate such Borrowing Base Deficiency, or (iii) eliminate such Borrowing Base Deficiency, through a combination of the actions described in clauses (i) and (ii). If, because of LC Exposure, a Borrowing Base Deficiency remains after prepaying all of the Loans and granting first priority Liens in additional Properties to the Administrative Agent, the Borrower shall pay to the Administrative Agent on behalf of the Lenders an amount equal to such remaining Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.10(b). (iii) Monthly Reduction Amount. If any reduction of the amount of the Borrowing Base by operation of the Monthly Reduction Amount in accordance with Section 2.08 results in a Borrowing Base Deficiency, then the Borrower shall immediately upon receipt of written notice thereof prepay the Loans in an aggregate 21 principal amount equal to such Borrowing Base Deficiency, together with interest on the principal amount paid accrued to the date of such prepayment. If, because of LC Exposure, a Borrowing Base Deficiency remains after prepaying all of the Loans, the Borrower shall pay to the Administrative Agent on behalf of the Lenders an amount equal to such remaining Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.10(b). (iv) Issuance of Senior Unsecured Notes. Proceeds received by the Borrower from the issuance of the Senior Unsecured Notes shall, no later than three Business Days after receipt thereof by the Borrower, be used, to the extent necessary, to prepay the aggregate principal amount of all Loans then outstanding, together with interest on the principal amount paid accrued to the date of such prepayment. (c) Generally. Prepayments permitted or required under this Section 2.07 shall be without premium or penalty, except as required under Section 5.05 for prepayment of LIBOR Loans. Any prepayment may be reborrowed subject to the then effective Aggregate Commitments. Section 2.08 Borrowing Base and Monthly Reduction Amount. (a) Generally. The Borrowing Base and the Monthly Reduction Amount shall be determined in accordance with Section 2.08(b) by the Administrative Agent with the concurrence of the Lenders and is subject to redetermination in accordance with Section 2.08(d). Upon any redetermination of the Borrowing Base or the Monthly Reduction Amount, such redetermination shall remain in effect until the next successive Redetermination Date. So long as any of the Commitments are in effect or any LC Exposure or Loans are outstanding hereunder, this facility shall be governed by the then effective Borrowing Base and Monthly Reduction Amount. During the period from and after the Closing Date until the first redetermination pursuant to Section 2.08(d) or adjusted pursuant to Section 8.08(c), the amount of the Borrowing Base shall be $65,000,000 and the Monthly Reduction Amount shall be $5,000,000.00; provided, however, if the Aquila Buy-Back and Closing Hedging Agreements are not completed prior to or on the Closing Date, the initial Borrowing Base shall be $60,000,000. No delay for any reason whatsoever in a redetermination of the Monthly Reduction Amount shall affect the Borrower's obligations under Section 2.07(b)(iii). (b) Redetermination Procedure. Upon receipt of the reports required by Section 8.07 and such other reports, data and supplemental information as may from time to time be reasonably requested by the Administrative Agent (the "Engineering Reports"), the Administrative Agent will redetermine the Borrowing Base and the Monthly Reduction Amount. Such redetermination will be in accordance with its normal and customary procedures for evaluating oil and gas reserves and other related assets as such exist at that particular time. The Administrative Agent, in its sole discretion, may make adjustments to the rates, volumes and prices and other assumptions set forth therein in accordance with its normal and customary procedures for evaluating oil and gas reserves and other related assets as such exist at that particular time. The Administrative Agent shall propose to the Lenders a new Borrowing Base and Monthly Reduction Amount within 15 days following receipt by the Administrative Agent and the Lenders of 22 the Engineering Reports in a timely and complete manner. After having received notice of such proposal by the Administrative Agent, the Lenders shall have 15 days to agree or disagree with such proposal. If at the end of the 15 days, the Lenders have not communicated their approval or disapproval, such silence shall be deemed to be an approval and the Administrative Agent's proposal shall be the new Borrowing Base and Monthly Reduction Amount. If however, the Lenders notify the Administrative Agent within 15 days of their disapproval, the Lenders shall, within a reasonable period of time, agree on a new Borrowing Base and Monthly Reduction Amount. The Administrative Agent and all of the Lenders must approve a new Borrowing Base and Monthly Reduction Amount. (c) Exclusions. The Administrative Agent may exclude any Oil and Gas Property or portion of production therefrom or any income from any other Property from the Borrowing Base, at any time, because title information is not reasonably satisfactory, such Property is not Mortgaged Property or such Property is not assignable. (d) Redetermination Dates. So long as any of the Commitments are in effect and until payment in full of all Loans hereunder, on or around the first Business Day of each April and October (each being a "Scheduled Redetermination Date"), the Lenders shall redetermine the amount of the Borrowing Base and the Monthly Reduction Amount in accordance with Section 2.08(b); provided, however, an interim redetermination of the Borrowing Base shall occur on or around July 31, 2001, which date shall be deemed a "Scheduled Redetermination Date". In addition, (i) the Borrower may initiate a redetermination of the Borrowing Base and the Monthly Reduction Amount at any other time as it so elects by specifying in writing to the Administrative Agent (who will promptly notify the Lenders) the date by which the Borrower will furnish to the Administrative Agent and the Lenders a Reserve Report in accordance with Section 8.07(b) and the date by which such redetermination is requested to occur; provided, however, that the Borrower may initiate only one such unscheduled redetermination per calendar year and (ii) the Administrative Agent may initiate a redetermination of the Borrowing Base and the Monthly Reduction Amount at any other time as it so elects by specifying in writing to the Borrower the date by which the Borrower is to furnish a Reserve Report in accordance with Section 8.07(b) and the date on which such redetermination is to occur; provided, however, that the Administrative Agent may initiate only one such unscheduled redetermination between each Scheduled Redetermination Date. Concurrently with the delivery of each Reserve Report delivered in connection with each unscheduled Borrowing Base redetermination requested by the Borrower, the Borrower shall pay an engineering fee to the Administrative Agent, for its own account, of $10,000. (e) Effective Date. The Administrative Agent shall promptly notify in writing the Borrower and the Lenders of the new Borrowing Base and Monthly Reduction Amount. Any redetermination of the Borrowing Base and the Monthly Reduction Amount shall not be in effect until written notice is received by the Borrower. (f) Redetermination Upon Issuance of Senior Unsecured Notes. The Borrowing Base and the Monthly Reduction Amount may be redetermined by the Administrative Agent and the Lenders, in accordance with their respective normal and 23 customary procedures for evaluating oil and gas reserves and other related assets as such exist at that particular time, promptly after the date of issuance of the Senior Unsecured Debt and such redetermination shall become effective in accordance with the procedures in Section 2.08(f). The foregoing redetermination of the Borrowing Base is in addition to any other unscheduled redetermination allowed pursuant to Section 2.08(d). Notwithstanding anything herein to the contrary, from and after the effective date of such redetermination until the next redetermination thereafter pursuant to Section 2.08(d), the Borrowing Base shall not exceed $20,000,000. Section 2.09 Assumption of Risks. The Borrower assumes all risks of the acts or omissions of any beneficiary of any Letter of Credit or any transferee thereof with respect to its use of such Letter of Credit. Neither the Issuing Bank (except in the case of gross negligence or willful misconduct on the part of the Issuing Bank or any of its employees), its correspondents nor any Lender shall be responsible for the validity, sufficiency or genuineness of certificates or other documents or any endorsements thereon, even if such certificates or other documents should in fact prove to be invalid, insufficient, fraudulent or forged; for errors, omissions, interruptions or delays in transmissions or delivery of any messages by mail, telex, or otherwise, whether or not they be in code; for errors in translation or for errors in interpretation of technical terms; the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; the failure of any beneficiary or any transferee of any Letter of Credit to comply fully with conditions required in order to draw upon any Letter of Credit; or for any other consequences arising from causes beyond the Issuing Bank's control or the control of the Issuing Bank's correspondents unless, as to any of the foregoing, constituting gross negligence or willful misconduct on the part of the Administrative Agent or any Lender. In addition, neither the Issuing Bank, the Administrative Agent nor any Lender shall be responsible for any error, neglect, or default of any of the Issuing Bank's correspondents; and none of the above shall affect, impair or prevent the vesting of any of the Issuing Bank's, the Administrative Agent's or any Lender's rights or powers hereunder or under the Letter of Credit Agreements, all of which rights shall be cumulative, unless, as to any of the foregoing, constituting gross negligence or willful misconduct on the part of the Administrative Agent or any Lender. The Issuing Bank and its correspondents may accept certificates or other documents that appear on their face to be in order, without responsibility for further investigation of any matter contained therein regardless of any notice or information to the contrary. In furtherance and not in limitation of the foregoing provisions, the Borrower agrees that any action, inaction or omission taken or not taken by the Issuing Bank or by any correspondent for the Issuing Bank in good faith in connection with any Letter of Credit, or any related drafts, certificates, documents or instruments, shall be binding on the Borrower and shall not put the Issuing Bank or its correspondents under any resulting liability to the Borrower. Section 2.10 Obligation to Reimburse and to Prepay. (a) If a disbursement by the Issuing Bank is made under any Letter of Credit, the Borrower shall pay to the Administrative Agent within two (2) Business Days after notice of any such disbursement is received by the Borrower, the amount of each such disbursement made by the Issuing Bank under the Letter of Credit (if such payment is not sooner effected as may be required under this Section 2.10 or under other provisions of 24 the Letter of Credit), together with interest on the amount disbursed from and including the date of disbursement until payment in full of such disbursed amount at a varying rate per annum equal to (i) the then applicable interest rate for Base Rate Loans through the second Business Day after notice of such disbursement is received by the Borrower and (ii) thereafter, the Post-Default Rate for Base Rate Loans (but in no event to exceed the Highest Lawful Rate) for the period from and including the third Business Day following the date of such disbursement to and including the date of repayment in full of such disbursed amount. The obligations of the Borrower under this Agreement with respect to each Letter of Credit shall be absolute, unconditional and irrevocable and shall be paid or performed strictly in accordance with the terms of this Agreement under all circumstances whatsoever, including, without limitation, but only to the fullest extent permitted by applicable law, the following circumstances: (i) any lack of validity or enforceability of this Agreement, any Letter of Credit or any of the Security Instruments; (ii) any amendment or waiver of (including any default), or any consent to departure from this Agreement (except to the extent permitted by any amendment or waiver), any Letter of Credit or any of the Security Instruments; (iii) the existence of any claim, set-off, defense or other rights which the Borrower may have at any time against the beneficiary of any Letter of Credit or any transferee of any Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the Issuing Bank, the Administrative Agent, any Lender or any other Person, whether in connection with this Agreement, any Letter of Credit, the Security Instruments, the transactions contemplated hereby or any unrelated transaction; (iv) any statement, certificate, draft, notice or any other document presented under any Letter of Credit proves to have been forged, fraudulent, insufficient or invalid in any respect or any statement therein proves to have been untrue or inaccurate in any respect whatsoever; (v) payment by the Issuing Bank under any Letter of Credit against presentation of a draft or certificate which appears on its face to comply, but does not comply, with the terms of such Letter of Credit; and (vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing. Notwithstanding anything in this Agreement to the contrary, the Borrower will not be liable for payment or performance that results from the gross negligence or willful misconduct of the Issuing Bank, except (i) where the Borrower or any Subsidiary actually recovers the proceeds for itself or the Issuing Bank of any payment made by the Issuing Bank in connection with such gross negligence or willful misconduct or (ii) in cases where the Administrative Agent makes payment to the named beneficiary of a Letter of Credit. (b) In the event of the occurrence of any Event of Default, a payment or prepayment pursuant to Section 2.07(b) or the maturity of the Notes, whether by acceleration or otherwise, an amount equal to the LC Exposure (or the excess in the case of Section 2.07(b)) shall be deemed to be forthwith due and owing by the Borrower to the Issuing Bank, the Administrative Agent and the Lenders as of the date of any such occurrence; and the Borrower's obligation to pay such amount shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any 25 defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower may now or hereafter have against any such beneficiary, the Issuing Bank, the Administrative Agent, the Lenders or any other Person for any reason whatsoever. Such payments shall be held by the Issuing Bank on behalf of the Lenders as cash collateral securing the LC Exposure in an account or accounts at the Principal Office; and the Borrower hereby grants to and by its deposit with the Administrative Agent grants to the Administrative Agent a security interest in such cash collateral. In the event of any such payment by the Borrower of amounts contingently owing under outstanding Letters of Credit and in the event that thereafter drafts or other demands for payment complying with the terms of such Letters of Credit are not made prior to the respective expiration dates thereof, the Administrative Agent agrees, if no Event of Default has occurred and is continuing or if no other amounts are outstanding under this Agreement, the Notes or the Security Instruments, to remit to the Borrower amounts for which the contingent obligations evidenced by the Letters of Credit have ceased. (c) Each Lender severally and unconditionally agrees that it shall promptly reimburse the Issuing Bank an amount equal to such Lender's Percentage Share of any disbursement made by the Issuing Bank under any Letter of Credit that is not reimbursed according to this Section 2.10. Section 2.11 Lending Offices. The Loans of each Type made by each Lender shall be made and maintained at such Lender's Applicable Lending Office for Loans of such Type. ARTICLE III PAYMENTS OF PRINCIPAL AND INTEREST Section 3.01 Repayment of Loans. (a) Loans. On the Termination Date the Borrower shall repay the outstanding aggregate principal amount of the Notes. (b) Generally. The Borrower will pay to the Administrative Agent, for the account of each Lender, the principal payments required by this Section 3.01. Section 3.02 Interest. (a) Interest Rates. The Borrower will pay to the Administrative Agent, for the account of each Lender, interest on the unpaid principal amount of each Loan made by such Lender for the period commencing on the date such Loan is made to, but excluding, the date such Loan shall be paid in full, at the following rates per annum: (i) if such a Loan is a Base Rate Loan, the Base Rate (as in effect from time to time) plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate; and 26 (ii) if such a Loan is a LIBOR Loan, for each Interest Period relating thereto, the LIBOR Rate for such Loan plus the Applicable Margin (as in effect from time to time), but in no event to exceed the Highest Lawful Rate. (b) Post-Default Rate. Notwithstanding the foregoing, the Borrower will pay to the Administrative Agent, for the account of each Lender, interest at the applicable Post-Default Rate on any principal of any Loan made by such Lender, and (to the fullest extent permitted by law) on any other amount payable by the Borrower hereunder, under any Loan Document or under any Note held by such Lender to or for the account of such Lender, for the period commencing on the date of an Event of Default until the same is paid in full or all Events of Default are cured or waived. (c) Due Dates. Accrued interest on Base Rate Loans shall be payable on each Quarterly Date commencing on June 30, 2001, and accrued interest on each LIBOR Loan shall be payable on the last day of the Interest Period therefor and, if such Interest Period is longer than three months, at three-month intervals following the first day of such Interest Period, except that interest payable at the Post-Default Rate shall be payable from time to time on demand and interest on any LIBOR Loan that is converted into a Base Rate Loan (pursuant to Section 5.04) shall be payable on the date of conversion (but only to the extent so converted). Any accrued and unpaid interest on the Loans on the Termination Date shall be paid on such date. (d) Determination of Rates. Promptly after the determination of any interest rate provided for herein or any change therein, the Administrative Agent shall notify the Lenders to which such interest is payable and the Borrower thereof. Each determination by the Administrative Agent of an interest rate or fee hereunder shall, except in cases of manifest error, be final, conclusive and binding on the parties. ARTICLE IV PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS; ETC. Section 4.01 Payments. Except to the extent otherwise provided herein, all payments of principal, interest and other amounts to be made by the Borrower or any Subsidiary under this Agreement, the Notes and the Letter of Credit Agreements shall be made in Dollars, in immediately available funds, to the Administrative Agent at such account as the Administrative Agent shall specify by notice to the Borrower from time to time, not later than 11:00 a.m. Houston, Texas time on the date on which such payments shall become due (each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day). Such payments shall be made without (to the fullest extent permitted by applicable law) defense, set-off or counterclaim. Each payment received by the Administrative Agent under this Agreement or any Note for account of a Lender shall be paid promptly to such Lender in immediately available funds. Except as otherwise provided in the definition of "Interest Period", if the due date of any payment under this Agreement or any Note would otherwise fall on a day which is not a Business Day such date shall be extended to the next succeeding Business Day and interest shall be payable for any principal so extended for the period of such extension. At the time of each payment to the Administrative Agent of any 27 principal of or interest on any borrowing, the Borrower shall notify the Administrative Agent of the Loans to which such payment shall apply. In the absence of such notice the Administrative Agent may specify the Loans to which such payment shall apply, but to the extent possible such payment or prepayment will be applied first to the Loans comprised of Base Rate Loans. Section 4.02 Pro Rata Treatment. Except to the extent otherwise provided herein each Lender agrees that: (i) each borrowing from the Lenders under Section 2.01 and each continuation and conversion under Section 2.02 shall be made from the Lenders pro rata in accordance with their Percentage Share, each payment of fees under Section 2.04(a) shall be made for account of the Lenders pro rata in accordance with their Percentage Share, and each termination or reduction of the amount of the Aggregate Maximum Credit Amounts under Section 2.03(b) shall be applied to the Commitment of each Lender, pro rata according to the amounts of its respective Commitment; (ii) each payment of principal of Loans by the Borrower shall be made for account of the Lenders pro rata in accordance with the respective unpaid principal amount of the Loans held by the Lenders; and (iii) each payment of interest on Loans by the Borrower shall be made for account of the Lenders pro rata in accordance with the amounts of interest due and payable to the respective Lenders; and (iv) each reimbursement by the Borrower of disbursements under Letters of Credit shall be made for account of the Issuing Bank or, if funded by the Lenders, pro rata for the account of the Lenders, in accordance with the amounts of reimbursement obligations due and payable to each respective Lender. Section 4.03 Computations. Interest on LIBOR Loans and fees shall be computed on the basis of a year of 360 days and actual days elapsed (including the first day but excluding the last day) occurring in the period for which such interest is payable, unless such calculation would exceed the Highest Lawful Rate, in which case interest shall be calculated on the per annum basis of a year of 365 or 366 days, as the case may be. Interest on Base Rate Loans shall be computed on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed (including the first day but excluding the last day) occurring in the period for which such interest is payable. Section 4.04 Non-receipt of Funds by the Administrative Agent. Unless the Administrative Agent shall have been notified by a Lender or the Borrower prior to the date on which such notifying party is scheduled to make payment to the Administrative Agent (in the case of a Lender) of the proceeds of a Loan or a payment under a Letter of Credit to be made by it hereunder or (in the case of the Borrower) a payment to the Administrative Agent for account of one or more of the Lenders hereunder (such payment being herein called the "Required Payment"), which notice shall be effective upon receipt, that it does not intend to make the Required Payment to the Administrative Agent, the Administrative Agent may assume that the Required Payment has been made and may, in reliance upon such assumption (but shall not be required to), make the amount thereof available to the intended recipient(s) on such date and, if such Lender or the Borrower (as the case may be) has not in fact made the Required Payment to the Administrative Agent, the recipient(s) of such payment shall, on demand, repay to the Administrative Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Administrative Agent until, but excluding, the date the Administrative Agent recovers such amount at a rate per annum which, for any Lender as recipient, will be equal to the Federal Funds 28 Rate, and for the Borrower as recipient, will be equal to the Base Rate plus the Applicable Margin. Section 4.05 Set-off, Sharing of Payments, Etc. (a) The Borrower agrees that, in addition to (and without limitation of) any right of set-off, bankers' lien or counterclaim a Lender may otherwise have, each Lender shall have the right and be entitled (after consultation with the Administrative Agent), at its option, to offset balances held by it or by any of its Affiliates for account of the Borrower at any of its offices, in Dollars or in any other currency, against any principal of or interest on any of such Lender's Loans, or any other amount payable to such Lender hereunder, which is not paid when due (regardless of whether such balances are then due to the Borrower), in which case it shall promptly notify the Borrower and the Administrative Agent thereof, provided that such Lender's failure to give such notice shall not affect the validity thereof. (b) If any Lender shall obtain payment of any principal of or interest on any Loan made by it to the Borrower under this Agreement (or reimbursement as to any Letter of Credit) through the exercise of any right of set-off, banker's lien or counterclaim or similar right or otherwise, and, as a result of such payment, such Lender shall have received a greater percentage of the principal or interest (or reimbursement) then due hereunder by the Borrower to such Lender than the percentage received by any other Lenders, it shall promptly (i) notify the Administrative Agent and each other Lender thereof and (ii) purchase from such other Lenders participations in (or, if and to the extent specified by such Lender, direct interests in) the Loans (or participations in Letters of Credit) made by such other Lenders (or in interest due thereon, as the case may be) in such amounts, and make such other adjustments from time to time as shall be equitable, to the end that all the Lenders shall share the benefit of such excess payment (net of any expenses which may be incurred by such Lender in obtaining or preserving such excess payment) pro rata in accordance with the unpaid principal and/or interest on the Loans held by each of the Lenders (or reimbursements of Letters of Credit). To such end all the Lenders shall make appropriate adjustments among themselves (by the resale of participations sold or otherwise) if such payment is rescinded or must otherwise be restored. The Borrower agrees that any Lender so purchasing a participation (or direct interest) in the Loans made by other Lenders (or in interest due thereon, as the case may be) may exercise all rights of set-off, banker's lien, counterclaim or similar rights with respect to such participation as fully as if such Lender were a direct holder of Loans (or Letters of Credit) in the amount of such participation. Nothing contained herein shall require any Lender to exercise any such right or shall affect the right of any Lender to exercise, and retain the benefits of exercising, any such right with respect to any other indebtedness or obligation of the Borrower. If under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured claim in lieu of a set-off to which this Section 4.05 applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders entitled under this Section 4.05 to share the benefits of any recovery on such secured claim. 29 Section 4.06 Taxes. (a) Payments Free and Clear. Any and all payments by the Borrower hereunder shall be made, in accordance with Section 4.01, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender, the Issuing Bank and the Administrative Agent, taxes imposed on its income, and franchise or similar taxes imposed on it, by (i) any jurisdiction (or political subdivision thereof) of which the Administrative Agent, the Issuing Bank or such Lender, as the case may be, is a citizen or resident or in which such Lender has an Applicable Lending Office, (ii) the jurisdiction (or any political subdivision thereof) in which the Administrative Agent, the Issuing Bank or such Lender is organized, or (iii) any jurisdiction (or political subdivision thereof) in which such Lender, the Issuing Bank or the Administrative Agent is presently doing business which taxes are imposed solely as a result of doing business in such jurisdiction (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as "Taxes"). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to the Lenders, the Issuing Bank or the Administrative Agent (i) the sum payable shall be increased by the amount necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 4.06) such Lender, the Issuing Bank or the Administrative Agent (as the case may be) shall receive an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxing authority or other Governmental Authority in accordance with applicable law. (b) Other Taxes. In addition, to the fullest extent permitted by applicable law, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made hereunder or from the execution, delivery or registration of, or otherwise with respect to, this Agreement, any Assignment or any Security Instrument (hereinafter referred to as "Other Taxes"). (C) INDEMNIFICATION. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE BORROWER WILL INDEMNIFY EACH LENDER AND THE ISSUING BANK AND THE ADMINISTRATIVE AGENT FOR THE FULL AMOUNT OF TAXES AND OTHER TAXES (INCLUDING, BUT NOT LIMITED TO, ANY TAXES OR OTHER TAXES IMPOSED BY ANY GOVERNMENTAL AUTHORITY ON AMOUNTS PAYABLE UNDER THIS SECTION 4.06) PAID BY SUCH LENDER, THE ISSUING BANK OR THE ADMINISTRATIVE AGENT (ON THEIR BEHALF OR ON BEHALF OF ANY LENDER), AS THE CASE MAY BE, AND ANY LIABILITY (INCLUDING PENALTIES, INTEREST AND EXPENSES) ARISING THEREFROM OR WITH RESPECT THERETO, WHETHER OR NOT SUCH TAXES OR OTHER TAXES WERE CORRECTLY OR LEGALLY ASSERTED UNLESS THE PAYMENT OF SUCH TAXES WAS NOT CORRECTLY OR LEGALLY ASSERTED AND SUCH LENDER'S PAYMENT OF SUCH TAXES OR OTHER TAXES WAS THE RESULT OF ITS GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. ANY PAYMENT PURSUANT TO SUCH INDEMNIFICATION SHALL BE MADE WITHIN 30 DAYS AFTER THE DATE ANY LENDER, THE ISSUING BANK OR THE ADMINISTRATIVE AGENT, 30 AS THE CASE MAY BE, MAKES WRITTEN DEMAND THEREFOR. IF ANY LENDER, THE ISSUING BANK OR THE ADMINISTRATIVE AGENT RECEIVES A REFUND OR CREDIT IN RESPECT OF ANY TAXES OR OTHER TAXES FOR WHICH SUCH LENDER, ISSUING BANK OR THE ADMINISTRATIVE AGENT HAS RECEIVED PAYMENT FROM THE BORROWER IT SHALL PROMPTLY NOTIFY THE BORROWER OF SUCH REFUND OR CREDIT AND SHALL, IF NO DEFAULT HAS OCCURRED AND IS CONTINUING, WITHIN 30 DAYS AFTER RECEIPT OF A REQUEST BY THE BORROWER (OR PROMPTLY UPON RECEIPT, IF THE BORROWER HAS REQUESTED APPLICATION FOR SUCH REFUND OR CREDIT PURSUANT HERETO), PAY AN AMOUNT EQUAL TO SUCH REFUND OR CREDIT TO THE BORROWER WITHOUT INTEREST (BUT WITH ANY INTEREST SO REFUNDED OR CREDITED), PROVIDED THAT THE BORROWER, UPON THE REQUEST OF SUCH LENDER, THE ISSUING BANK OR THE ADMINISTRATIVE AGENT, AGREES TO RETURN SUCH REFUND OR CREDIT (PLUS PENALTIES, INTEREST OR OTHER CHARGES) TO SUCH LENDER OR THE ADMINISTRATIVE AGENT IN THE EVENT SUCH LENDER OR THE ADMINISTRATIVE AGENT IS REQUIRED TO REPAY SUCH REFUND OR CREDIT. (d) Lender Representations. (i) Each Lender represents that it is either (1) a banking association or corporation organized under the laws of the United States of America or any state thereof or (2) it is entitled to complete exemption from United States withholding tax imposed on or with respect to any payments, including fees, to be made to it pursuant to this Agreement (A) under an applicable provision of a tax convention to which the United States of America is a party or (B) because it is acting through a branch, agency or office in the United States of America and any payment to be received by it hereunder is effectively connected with a trade or business in the United States of America. Each Lender that is not a banking association or corporation organized under the laws of the United States of America or any state thereof agrees to provide to the Borrower and the Administrative Agent on the Closing Date, or on the date of its delivery of the Assignment pursuant to which it becomes a Lender, and at such other times as required by United States law or as the Borrower or the Administrative Agent shall reasonably request, two accurate and complete original signed copies of either (A) Internal Revenue Service Form W-8ECI (or successor form) certifying that all payments to be made to it hereunder will be effectively connected to a United States trade or business (the "Form W-8ECI Certification") or (B) Internal Revenue Service Form W-8BEN (or successor form) certifying that it is entitled to the benefit of a provision of a tax convention to which the United States of America is a party which completely exempts from United States withholding tax all payments to be made to it hereunder (the "Form W-8BEN Certification"). In addition, each Lender agrees that if it previously filed a Form W-8ECI Certification, it will deliver to the Borrower and the Administrative Agent a new Form W-8ECI Certification prior to the first payment date occurring in each of its subsequent taxable years; and if it previously filed a Form W-8BEN Certification, it will deliver to the Borrower and the Administrative Agent a new certification prior to the first payment date falling in the third year following the previous filing of such certification. Each Lender also agrees to deliver to the Borrower and the Administrative Agent such other or supplemental forms as may at any time be required as a result of changes in applicable law or regulation in order to confirm or maintain in effect its entitlement to exemption 31 from United States withholding tax on any payments hereunder, provided that the circumstances of such Lender at the relevant time and applicable laws permit it to do so. If a Lender determines, as a result of any change in either (i) a Governmental Requirement or (ii) its circumstances, that it is unable to submit any form or certificate that it is obligated to submit pursuant to this Section 4.06, or that it is required to withdraw or cancel any such form or certificate previously submitted, it shall promptly notify the Borrower and the Administrative Agent of such fact. If a Lender is organized under the laws of a jurisdiction outside the United States of America, unless the Borrower and the Administrative Agent have received a Form W-8BEN Certification or Form W-8ECI Certification satisfactory to them indicating that all payments to be made to such Lender hereunder are not subject to United States withholding tax, the Borrower shall withhold taxes from such payments at the applicable statutory rate. Each Lender agrees to indemnify and hold harmless the Borrower or Administrative Agent, as applicable, from any United States taxes, penalties, interest and other expenses, costs and losses incurred or payable by (i) the Administrative Agent as a result of such Lender's failure to submit any form or certificate that it is required to provide pursuant to this Section 4.06 or (ii) the Borrower or the Administrative Agent as a result of their reliance on any such form or certificate which such Lender has provided to them pursuant to this Section 4.06. (ii) For any period with respect to which a Lender has failed to provide the Borrower with the form required pursuant to this Section 4.06, if any, (other than if such failure is due to a change in a Governmental Requirement occurring subsequent to the date on which a form originally was required to be provided), such Lender shall not be entitled to indemnification under Section 4.06 with respect to taxes imposed by the United States which taxes would not have been imposed but for such failure to provide such forms; provided, however, that if a Lender, which is otherwise exempt from or subject to a reduced rate of withholding tax, becomes subject to taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as such Lender shall reasonably request to assist such Lender to recover such taxes. (iii) Any Lender claiming any additional amounts payable pursuant to this Section 4.06 shall use reasonable efforts (consistent with legal and regulatory restrictions) to file any certificate or document requested by the Borrower or the Administrative Agent or to change the jurisdiction of its Applicable Lending Office or to contest any tax imposed if the making of such a filing or change or contesting such tax would avoid the need for or reduce the amount of any such additional amounts that may thereafter accrue and would not, in the sole determination of such Lender, be otherwise disadvantageous to such Lender. Section 4.07 Disposition of Proceeds. The Mortgage contains an assignment by the Borrower unto and in favor of the Administrative Agent for the benefit of the Lenders of all production and all proceeds attributable thereto which may be produced from or allocated to the Mortgaged Property, and the Mortgage further provides in general for the application of such proceeds to the satisfaction of the Obligations and other indebtedness, liabilities and obligations described therein and secured thereby. Notwithstanding the assignment contained in the Mortgage, until the occurrence of an Event of Default, the Lenders agree that they will neither notify the purchaser or purchasers of such production nor take any other action to cause such 32 proceeds to be remitted to the Lenders, but the Lenders will instead permit such proceeds to be paid to the Borrower. ARTICLE V CAPITAL ADEQUACY AND ADDITIONAL COSTS Section 5.01 Additional Costs. (a) LIBOR Regulations, etc. The Borrower shall pay directly to each Lender from time to time such amounts as such Lender may determine to be necessary to compensate such Lender for any costs which it determines are attributable to its making or maintaining of any LIBOR Loans or issuing or participating in Letters of Credit hereunder or its obligation to make any LIBOR Loans or issue or participate in any Letters of Credit hereunder, or any reduction in any amount receivable by such Lender hereunder in respect of any of such LIBOR Loans, Letters of Credit or such obligation (such increases in costs and reductions in amounts receivable being herein called "Additional Costs"), resulting from any Regulatory Change which: (i) changes the basis of taxation of any amounts payable to such Lender under this Agreement or any Note in respect of any of such LIBOR Loans or Letters of Credit (other than taxes imposed on the overall net income of such Lender or of its Applicable Lending Office for any of such LIBOR Loans by the jurisdiction in which such Lender has its principal office or Applicable Lending Office); or (ii) imposes or modifies any reserve, special deposit, minimum capital, capital ratio or similar requirements relating to any extensions of credit or other assets of, or any deposits with or other liabilities of such Lender, or the Commitment or Loans of such Lender or the London interbank market; or (iii) imposes any other condition affecting this Agreement or any Note (or any of such extensions of credit or liabilities) or such Lender's Commitment or Loans. Each Lender will notify the Administrative Agent and the Borrower of any event occurring after the Closing Date which will entitle such Lender to compensation pursuant to this Section 5.01(a) as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, and will designate a different Applicable Lending Office for the Loans of such Lender affected by such event if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of such Lender, be disadvantageous to such Lender, provided that such Lender shall have no obligation to so designate an Applicable Lending Office located in the United States. If any Lender requests compensation from the Borrower under this Section 5.01(a), the Borrower may, by notice to such Lender, suspend the obligation of such Lender to make additional Loans of the Type with respect to which such compensation is requested until the Regulatory Change giving rise to such request ceases to be in effect (in which case the provisions of Section 5.04 shall be applicable). (b) Regulatory Change. Without limiting the effect of the provisions of Section 5.01(a), in the event that at any time (by reason of any Regulatory Change or any other circumstances arising after the Closing Date affecting (A) any Lender, (B) the London interbank market or (C) such Lender's position in such market), the LIBOR Rate, as determined in good faith by such Lender, will not adequately and fairly reflect the cost 33 to such Lender of funding its LIBOR Loans, then, if such Lender so elects, by notice to the Borrower and the Administrative Agent, the obligation of such Lender to make additional LIBOR Loans shall be suspended until such Regulatory Change or other circumstances ceases to be in effect (in which case the provisions of Section 5.04 shall be applicable). (c) Capital Adequacy. Without limiting the effect of the foregoing provisions of this Section 5.01 (but without duplication), the Borrower shall pay directly to any Lender from time to time on request such amounts as such Lender may reasonably determine to be necessary to compensate such Lender or its parent or holding company for any costs which it determines are attributable to the maintenance by such Lender or its parent or holding company (or any Applicable Lending Office), pursuant to any Governmental Requirement following any Regulatory Change, of capital in respect of its Commitment, its Note, or its Loans or any interest held by it in any Letter of Credit, such compensation to include, without limitation, an amount equal to any reduction of the rate of return on assets or equity of such Lender or its parent or holding company (or any Applicable Lending Office) to a level below that which such Lender or its parent or holding company (or any Applicable Lending Office) could have achieved but for such Governmental Requirement. Such Lender will notify the Borrower that it is entitled to compensation pursuant to this Section 5.01(c) as promptly as practicable after it determines to request such compensation. (d) Compensation Procedure. Any Lender notifying the Borrower of the incurrence of Additional Costs under this Section 5.01 shall in such notice to the Borrower and the Administrative Agent set forth in reasonable detail the basis and amount of its request for compensation. Determinations and allocations by each Lender for purposes of this Section 5.01 of the effect of any Regulatory Change pursuant to Section 5.01(a) or (b), or of the effect of capital maintained pursuant to Section 5.01(c), on its costs or rate of return of maintaining Loans or its obligation to make Loans or issue Letters of Credit, or on amounts receivable by it in respect of Loans or Letters of Credit, and of the amounts required to compensate such Lender under this Section 5.01, shall be conclusive and binding for all purposes, provided that such determinations and allocations are made on a reasonable basis. Any request for additional compensation under this Section 5.01 shall be paid by the Borrower within thirty (30) days of the receipt by the Borrower of the notice described in this Section 5.01(d)(c). Section 5.02 Limitation on LIBOR Loans. Anything herein to the contrary notwithstanding, if, on or prior to the determination of any LIBOR Rate for any Interest Period: (i) the Administrative Agent determines (which determination shall be conclusive, absent manifest error) that quotations of interest rates for the relevant deposits referred to in the definition of "LIBOR Rate" in Section 1.02 are not being provided in the relevant amounts or for the relevant maturities for purposes of determining rates of interest for LIBOR Loans as provided herein; or (ii) the Administrative Agent determines (which determination shall be conclusive, absent manifest error) that the relevant rates of interest referred to in the definition of "LIBOR Rate" in Section 1.02 upon the basis of which the rate of interest 34 for LIBOR Loans for such Interest Period is to be determined are not sufficient to adequately cover the cost to the Lenders of making or maintaining LIBOR Loans; then the Administrative Agent shall give the Borrower prompt notice thereof, and so long as such condition remains in effect, the Lenders shall be under no obligation to make additional LIBOR Loans. Section 5.03 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its Applicable Lending Office to honor its obligation to make or maintain LIBOR Loans hereunder, then such Lender shall promptly notify the Borrower thereof and such Lender's obligation to make LIBOR Loans shall be suspended until such time as such Lender may again make and maintain LIBOR Loans (in which case the provisions of Section 5.04 shall be applicable). Section 5.04 Base Rate Loans Pursuant to Sections 5.01, 5.02 and 5.03. If the obligation of any Lender to make LIBOR Loans shall be suspended pursuant to Sections 5.01, 5.02 or 5.03 ("Affected Loans"), all Affected Loans which would otherwise be made by such Lender shall be made instead as Base Rate Loans (and, if an event referred to in Section 5.01(b) or Section 5.03 has occurred and such Lender so requests by notice to the Borrower, all Affected Loans of such Lender then outstanding shall be automatically converted into Base Rate Loans on the date specified by such Lender in such notice) and, to the extent that Affected Loans are so made as (or converted into) Base Rate Loans, all payments of principal which would otherwise be applied to such Lender's Affected Loans shall be applied instead to its Base Rate Loans. Section 5.05 Compensation. The Borrower shall pay to each Lender within thirty (30) days of receipt of written request of such Lender (which request shall set forth, in reasonable detail, the basis for requesting such amounts and which shall be conclusive and binding for all purposes provided that such determinations are made on a reasonable basis), such amount or amounts as shall compensate it for any loss, cost, expense or liability which such Lender determines are attributable to: (i) any payment, prepayment or conversion of a LIBOR Loan properly made by such Lender or the Borrower for any reason (including, without limitation, the acceleration of the Loans pursuant to Section 10.01) on a date other than the last day of the Interest Period for such Loan; or (ii) any failure by the Borrower for any reason (including but not limited to, the failure of any of the conditions precedent specified in Article VI to be satisfied) to borrow, continue or convert a LIBOR Loan from such Lender on the date for such borrowing, continuation or conversion specified in the relevant notice given pursuant to Section 2.02(c). Without limiting the effect of the preceding sentence, such compensation shall include an amount equal to the excess, if any, of (i) the amount of interest which would have accrued on the principal amount so paid, prepaid or converted or not borrowed for the period from the date of such payment, prepayment or conversion or failure to borrow to the last day of the Interest Period for such Loan (or, in the case of a failure to borrow, the Interest Period for such Loan which would have commenced on the date specified for such borrowing) at the applicable rate of 35 interest for such Loan provided for herein over (ii) the interest component of the amount such Lender would have bid in the London interbank market for Dollar deposits of leading banks in amounts comparable to such principal amount and with maturities comparable to such period (as reasonably determined by such Lender). Section 5.06 Replacement Lenders. (a) If any Lender has notified the Borrower and the Agent of its incurring Additional Costs under Section 5.01 or has required the Borrower to make payments for Taxes under Section 4.06, then the Borrower may, unless such Lender has notified the Borrower and the Agent that the circumstances giving rise to such notice no longer apply, terminate, in whole but not in part, the Commitment of any Lender (other than the Agent) (the "Terminated Lender") at any time upon five (5) Business Days' prior written notice to the Terminated Lender and the Agent (such notice referred to herein as a "Notice of Termination"). (b) In order to effect the termination of the Commitment of the Terminated Lender, the Borrower shall: (i) obtain an agreement with one or more Lenders to increase their Commitment or Commitments and/or (ii) request any one or more other banking institutions to become parties to this Agreement in place and instead of such Terminated Lender and agree to accept a Commitment or Commitments; provided, however, that such one or more other banking institutions are reasonably acceptable to the Agent and become parties by executing an Assignment (the Lenders or other banking institutions that agree to accept in whole or in part the Commitment of the Terminated Lender being referred to herein as the "Replacement Lenders"), such that the aggregate increased and/or accepted Commitments of the Replacement Lenders under clauses (i) and (ii) above equal the Commitment of the Terminated Lender. (c) The Notice of Termination shall include the name of the Terminated Lender, the date the termination will occur (the "Lender Termination Date"), and the Replacement Lender or Replacement Lenders to which the Terminated Lender will assign its Commitment and, if there will be more than one Replacement Lender, the portion of the Terminated Lender's Commitment to be assigned to each Replacement Lender. (d) On the Lender Termination Date, (i) the Terminated Lender shall by execution and delivery of an Assignment assign its Commitment to the Replacement Lender or Replacement Lenders (pro rata, if there is more than one Replacement Lender, in proportion to the portion of the Terminated Lender's Commitment to be assigned to each Replacement Lender) indicated in the Notice of Termination and shall assign to the Replacement Lender or Replacement Lenders each of its Loans (if any) then outstanding and participation interests in Letters of Credit (if any) then outstanding pro rata as aforesaid), (ii) the Terminated Lender shall endorse its Note, payable without recourse, representation or warranty to the order of the Replacement Lender or Replacement Lenders (pro rata as aforesaid), (iii) the Replacement Lender or Replacement Lenders shall purchase the Note held by the Terminated Lender (pro rata as aforesaid) at a price equal to the unpaid principal amount thereof plus interest and facility and other fees accrued and unpaid to the Lender Termination Date, and (iv) the Replacement Lender or 36 Replacement Lenders will thereupon (pro rata as aforesaid) succeed to and be substituted in all respects for the Terminated Lender with like effect as if becoming a Lender pursuant to the terms of Section 12.06(b), and the Terminated Lender will have the rights and benefits of an assignor under Section 12.06(b). To the extent not in conflict, the terms of Section 12.06(b) shall supplement the provisions of this Section 5.06(d). For each assignment made under this Section 5.06, the Replacement Lender shall pay to the Agent the processing fee provided for in Section 12.06(b). The Borrower will be responsible for the payment of any breakage costs associated with termination and Replacement Lenders, as set forth in Section 5.05. ARTICLE VI CONDITIONS PRECEDENT Section 6.01 Initial Funding. The obligation of the Lenders to make the Initial Funding is subject to the receipt by the Administrative Agent and the Lenders of all fees payable pursuant to Section 2.04 on or before the Closing Date and the receipt by the Administrative Agent of the following documents (in sufficient original counterparts, other than the Notes, for each Lender) and satisfaction of the other conditions provided in this Section 6.01, each of which shall be reasonably satisfactory to the Administrative Agent in form and substance: (a) A certificate of the Secretary or an Assistant Secretary of the Borrower setting forth (i) resolutions of its board of directors with respect to the authorization of the Borrower to execute and deliver the Loan Documents to which it is a party and to enter into the transactions contemplated in those documents, (ii) the officers of the Borrower (y) who are authorized to sign the Loan Documents to which the Borrower is a party and (z) who will, until replaced by another officer or officers duly authorized for that purpose, act as its representative for the purposes of signing documents and giving notices and other communications in connection with this Agreement and the transactions contemplated hereby, (iii) specimen signatures of the authorized officers, and (iv) the articles or certificate of incorporation and bylaws of the Borrower, certified as being true and complete.

(o) The transactions relating to the Aquila Buy-Back and the Closing Hedging Agreements shall have been completed and all documents to be entered into in connection therewith shall have been executed and delivered. Section 6.02 Initial and Subsequent Loans and Letters of Credit. The obligation of the Lenders to make Loans to the Borrower upon the occasion of each borrowing hereunder and to issue, renew, extend or reissue Letters of Credit for the account of the Borrower (including the 38 Initial Funding) is subject to the further conditions precedent that, as of the date of such Loans and after giving effect thereto: (a) no Default shall exist; (b) no Material Adverse Effect shall have occurred; and (c) the representations and warranties made by the Borrower in Article VII and in the Security Instruments shall be true on and as of the date of the making of such Loans or issuance, renewal, extension or reissuance of a Letter of Credit with the same force and effect as if made on and as of such date and following such new borrowing, except to the extent such representations and warranties are expressly limited to an earlier date or the Majority Lenders may expressly consent in writing to the contrary. Each request for a borrowing or issuance, renewal, extension or reissuance of a Letter of Credit by the Borrower hereunder shall constitute a certification by the Borrower to the effect set forth in Section 6.02(c) (both as of the date of such notice and, unless the Borrower otherwise notifies the Administrative Agent prior to the date of and immediately following such borrowing or issuance, renewal, extension or resistance of a Letter of Credit as of the date thereof). Section 6.03 Conditions Precedent for the Benefit of Lenders. All conditions precedent to the obligations of the Lenders to make any Loan are imposed hereby solely for the benefit of the Lenders, and no other Person may require satisfaction of any such condition precedent or be entitled to assume that the Lenders will refuse to make any Loan in the absence of strict compliance with such conditions precedent. Section 6.04 No Waiver. No waiver of any condition precedent shall preclude the Administrative Agent or the Lenders from requiring such condition to be met prior to making any subsequent Loan or preclude the Lenders from thereafter declaring that the failure of the Borrower to satisfy such condition precedent constitutes a Default. ARTICLE VII REPRESENTATIONS AND WARRANTIES The Borrower represents and warrants to the Administrative Agent and the Lenders that (each representation and warranty herein is given as of the Closing Date and shall be deemed repeated and reaffirmed on the dates of each borrowing and issuance, renewal, extension or resistance of a Letter of Credit as provided in Section 6.02): Section 7.01 Corporate Existence. The Borrower and each of its Subsidiaries: (i) is a corporation duly organized, legally existing and in good standing under the laws of the jurisdiction of its incorporation; (ii) has all requisite corporate power, and has all material governmental licenses, authorizations, consents and approvals necessary to own its assets and carry on its business as now being or as proposed to be conducted; and (iii) is qualified to do business in all jurisdictions in which the nature of the business conducted by it makes such qualification necessary and where failure so to qualify would have a Material Adverse Effect. 39 Section 7.02 Financial Condition.

Since December 31, 2000, there has been no change or event having a Material Adverse Effect. Since the date of the most recent Financial Statements, neither the business nor the Properties of the Borrower or any Subsidiary have been materially and adversely affected as a result of any fire, explosion, earthquake, flood, drought, windstorm, accident, strike or other labor disturbance, embargo, requisition or taking of Property or cancellation of contracts, permits or concessions by any Governmental Authority, riot, activities of armed forces or acts of God or of any public enemy.

Except as disclosed to the Lenders in Schedule 7.03 hereto, at the Closing Date there is no litigation, legal, administrative or arbitrage proceeding, investigation or other action of any nature pending or, to the knowledge of the Borrower, threatened against or affecting the Borrower or any Subsidiary which involves the possibility of any judgment or liability against the Borrower or any Subsidiary not fully covered by insurance (except for normal deductibles) and which would have a Material Adverse Effect. Section 7.04 No Breach. Neither the execution and delivery of the Loan Documents, nor compliance with the terms and provisions hereof will conflict with or result in a breach of, or require any consent which has not been obtained as of the Closing Date under, the respective charter or by-laws of the Borrower or any Subsidiary, or any Governmental Requirement or any agreement or instrument to which the Borrower or any Subsidiary is a party or by which it is bound or to which it or its Properties are subject, or constitute a default under any such agreement or instrument, or result in the creation or imposition of any Lien upon any of the revenues or assets of the Borrower or any Subsidiary pursuant to the terms of any such agreement or instrument other than the Liens created by any of the Loan Documents. Section 7.05 Authority. The Borrower has all necessary corporate power and authority to execute, deliver and perform its obligations under the Loan Documents to which it is a party; and the execution, delivery and performance by the Borrower of the Loan Documents to which it is a party have been duly authorized by all necessary corporate action on its part; and the Loan Documents to which it is a party constitute the legal, valid and binding obligations of the Borrower, enforceable in accordance with their terms. Section 7.06 Approvals. No authorizations, approvals or consents of, and no filings or registrations with, any Governmental Authority are necessary for the execution, delivery or performance by the Borrower of the Loan Documents to which is a party or for the validity or enforceability thereof, except for the routine recording and filing of certain of the Security Instruments. 40 Section 7.07 Use of Loans.

The Borrower is not engaged principally, or as one of its 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 of Governors of the Federal Reserve System) and no part of the proceeds of any Loan hereunder will be used to buy or carry any margin stock. Section 7.08 ERISA. (a) The Borrower, each Subsidiary and each ERISA Affiliate have complied in all material respects with ERISA and, where applicable, the Code regarding each Plan. (b) Each Plan is, and has been, maintained in substantial compliance with ERISA and, where applicable, the Code. (c) No act, omission or transaction has occurred which could result in imposition on the Borrower, any Subsidiary or any ERISA Affiliate (whether directly or indirectly) of (i) either a civil penalty assessed pursuant to section 502(c), (i) or (l) of ERISA or a tax imposed pursuant to Chapter 43 of Subtitle D of the Code or (ii) breach of fiduciary duty liability damages under section 409 of ERISA. (d) No Plan (other than a defined contribution plan) or any trust created under any such Plan has been terminated since September 2, 1974.

(f) The actuarial present value of the benefit liabilities under each Plan which is subject to Title IV of ERISA does not, as of the end of the Borrower's most recently ended fiscal year, exceed the current value of the assets (computed on a plan termination basis in accordance with Title IV of ERISA) of such Plan allocable to such benefit liabilities. The term "actuarial present value of the benefit liabilities" shall have the meaning specified in section 4041 of ERISA. (g) None of the Borrower, any Subsidiary or any ERISA Affiliate sponsors, maintains, or contributes to an employee welfare benefit plan, as defined in section 3(1) of ERISA, including, without limitation, any such plan maintained to provide benefits to former employees of such entities, that may not be terminated by the Borrower, a Subsidiary or any ERISA Affiliate in its sole discretion at any time without any material liability. 41 (h) None of the Borrower, any Subsidiary or any ERISA Affiliate sponsors, maintains or contributes to, or has at any time in the preceding six calendar years, sponsored, maintained or contributed to, any Multiemployer Plan.

Section 7.09 Taxes. Except as set out in Schedule 7.09, each of the Borrower and its Subsidiaries has filed all United States federal income tax returns and all other tax returns which are required to be filed (giving effect to any timely filed extensions) by them and have paid all material taxes due pursuant to such returns or pursuant to any assessment received by the Borrower or any Subsidiary. The charges, accruals and reserves on the books of the Borrower and its Subsidiaries in respect of taxes and other governmental charges are, in the opinion of the Borrower, adequate.

Except as set forth in Schedule 7.10, after giving full effect to the Excepted Liens, the Borrower owns the net interests in production attributable to the Hydrocarbon Interests reflected in the most recently delivered Reserve Report and the ownership of such Properties shall not in any material respect obligate the Borrower 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 Reserve Report. All information contained in the most recently delivered Reserve Report is true and correct in all material respects as of the date thereof. (b) All leases and agreements necessary for the conduct of the business of the Borrower and its 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 would affect in any material respect the conduct of the business of the Borrower and its Subsidiaries.

Section 7.11 No Material Misstatements. No written information, statement, exhibit, certificate, document or report furnished to the Administrative Agent and the Lenders (or any of them) by the Borrower or any Subsidiary in connection with the negotiation of this Agreement contained any material misstatement of fact or omitted to state a material fact or any fact necessary to make the statement contained therein not materially misleading in the light of the circumstances in which made and with respect to the Borrower and its Subsidiaries taken as a whole. There is no fact peculiar to the Borrower or any Subsidiary which has a Material Adverse Effect or in the future is reasonably likely to have (so far as the Borrower can now foresee) a Material Adverse Effect and which has not been set forth in this Agreement or the other documents, certificates and statements furnished to the Administrative Agent by or on behalf of the Borrower or any Subsidiary prior to, or on, the Closing Date in connection with the transactions contemplated hereby.

Section 11.06 Non-Reliance on Administrative Agent and other Lenders. Each Lender acknowledges and agrees that it has, independently and without reliance on the Administrative Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own credit analysis of the Borrower and its decision to enter into this Agreement, and that it will, independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under this Agreement. The Administrative Agent shall not be required to keep itself informed as to the 65 performance or observance by the Borrower of this Agreement, the Notes, the Security Instruments or any other document referred to or provided for herein or to inspect the properties or books of the Borrower. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Administrative Agent hereunder, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or business of the Borrower (or any of its Affiliates) which may come into the possession of the Administrative Agent or any of its Affiliates. In this regard, each Lender acknowledges that Winstead Sechrest & Minick P.C. is acting in this transaction as special counsel to the Administrative Agent only, except to the extent otherwise expressly stated in any legal opinion or any Loan Document. Each Lender will consult with its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated therein. Section 11.07 Action by Administrative Agent. Except for action or other matters expressly required of the Administrative Agent hereunder, the Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder unless it shall (i) receive written instructions from the Majority Lenders (or all of the Lenders as expressly required by Section 12.04) specifying the action to be taken, and (ii) be indemnified to its satisfaction by the Lenders against any and all liability and expenses which may be incurred by it by reason of taking or continuing to take any such action. The instructions of the Majority Lenders (or all of the Lenders as expressly required by Section 12.04) and any action taken or failure to act pursuant thereto by the Administrative Agent shall be binding on all of the Lenders. If a Default has occurred and is continuing, the Administrative Agent shall take such action with respect to such Default as shall be directed by the Majority Lenders (or all of the Lenders as required by Section 12.04) in the written instructions (with indemnities) described in this Section 11.07, provided that, unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best interests of the Lenders. In no event, however, shall the Administrative Agent be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement and the Security Instruments or applicable law.

Section 12.14 Interest. It is the intention of the parties hereto that each Lender shall conform strictly to usury laws applicable to it. Accordingly, if the transactions contemplated hereby would be usurious as to any Lender under laws applicable to it (including the laws of the United States of America and the State of New York or any other jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in any of the Loan 73 Documents or any agreement entered into in connection with or as security for the Notes, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under law applicable to any Lender that is contracted for, taken, reserved, charged or received by such Lender under any of the Loan Documents or agreements or otherwise in connection with the Notes shall under no circumstances exceed the maximum amount allowed by such applicable law, and any excess shall be canceled automatically and if theretofore paid shall be credited by such Lender on the principal amount of the Obligations (or, to the extent that the principal amount of the Obligations shall have been or would thereby be paid in full, refunded by such Lender to the Borrower); and (ii) in the event that the maturity of the Notes is accelerated by reason of an election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to any Lender may never include more than the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by such Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the principal amount of the Obligations (or, to the extent that the principal amount of the Obligations shall have been or would thereby be paid in full, refunded by such Lender to the Borrower). All sums paid or agreed to be paid to any Lender for the use, forbearance or detention of sums due hereunder shall, to the extent permitted by law applicable to such Lender, be amortized, prorated, allocated and spread throughout the full term of the Loans evidenced by the Notes until payment in full so that the rate or amount of interest on account of any Loans hereunder does not exceed the maximum amount allowed by such applicable law. If at any time and from time to time (i) the amount of interest payable to any Lender on any date shall be computed at the Highest Lawful Rate applicable to such Lender pursuant to this Section 12.14 and (ii) in respect of any subsequent interest computation period the amount of interest otherwise payable to such Lender would be less than the amount of interest payable to such Lender computed at the Highest Lawful Rate applicable to such Lender, then the amount of interest payable to such Lender in respect of such subsequent interest computation period shall continue to be computed at the Highest Lawful Rate applicable to such Lender until the total amount of interest payable to such Lender shall equal the total amount of interest which would have been payable to such Lender if the total amount of interest had been computed without giving effect to this Section 12.14. Section 12.15 Confidentiality. In the event that the Borrower provides to the Administrative Agent or the Lenders written confidential information belonging to the Borrower, if the Borrower shall denominate such information in writing as "confidential", the Administrative Agent and the Lenders shall thereafter maintain such information in confidence in accordance with the standards of care and diligence that each utilizes in maintaining its own confidential information. This obligation of confidence shall not apply to such portions of the information which (i) are in the public domain, (ii) hereafter become part of the public domain without the Administrative Agent or the Lenders breaching their obligation of confidence to the Borrower, (iii) are previously known by the Administrative Agent or the Lenders from some source other than the Borrower, (iv) are hereafter developed by the Administrative Agent or the Lenders without using the Borrower's information, (v) are hereafter obtained by or available to the Administrative Agent or the Lenders from a third party who owes no obligation of confidence to the Borrower with respect to such information or through any other means other than through disclosure by the Borrower, (vi) are disclosed with the Borrower's consent, (vii) 74 must be disclosed either pursuant to any Governmental Requirement or to Persons regulating the activities of the Administrative Agent or the Lenders, or (viii) as may be required by law or regulation or order of any Governmental Authority in any judicial, arbitration or governmental proceeding. Further, the Administrative Agent or a Lender may disclose any such information to any other Lender, any independent petroleum engineers or consultants, any independent certified public accountants, any legal counsel employed by such Person in connection with this Agreement or any Security Instrument, including without limitation, the enforcement or exercise of all rights and remedies thereunder, or any assignee or participant (including prospective assignees and participants) in the Loans; provided, however, that the Administrative Agent or the Lenders shall receive a confidentiality agreement from the Person to whom such information is disclosed such that said Person shall have the same obligation to maintain the confidentiality of such information as is imposed upon the Administrative Agent or the Lenders hereunder. Notwithstanding anything to the contrary provided herein, this obligation of confidence shall cease three years from the date the information was furnished, unless the Borrower requests in writing at least 30 days prior to the expiration of such three year period, to maintain the confidentiality of such information for an additional three year period.
