(b) From the date hereof through the Maturity Date and subject to the further provisions of this Section 2.2, the Borrowing Base shall be redetermined by the Majority Banks each May 1 and November 1 in accordance with Section 2.2(d) on the basis of information, including the Oil and Gas Reserve Reports required to be delivered before each such date supplied by Borrower in compliance with the provisions of this Agreement, such additional data concerning pricing, quantities of production, purchasers of production, and other information and engineering and geological data with respect thereto as the Agent or any Bank may reasonably request, together with all other information then available to the Agent and the Banks.

(d) Upon a redetermination of the Borrowing Base, the Agent shall propose a Borrowing Base to the Banks, and the Banks shall vote to approve or disapprove such proposed Borrowing Base. If the Majority Banks do not approve the proposed Borrowing Base, the Agent shall propose, and the Banks shall vote to approve or disapprove, another Borrowing Base, until the Majority Banks approve a Borrowing Base proposed by the Agent. Once the Majority Banks approve the proposed Borrowing Base, the Agent shall notify the Borrower of such redetermination. Until the Borrower receives such notification from the Agent, the Borrowing Base most recently established shall remain in effect, and thereafter the new Borrowing Base as set forth in such notification shall be in effect. -14- (e) (i) Upon any asset sale permitted under Section 6.4(b)(ii), the Borrowing Base shall automatically be reduced on the date of such sale by subtracting from the Borrowing Base the value of the assets sold as determined from the most recent information compiled by the Agent and the Banks in connection with the most recent redetermination of the Borrowing Base and (ii) upon the issuance of any Debt permitted under Section 6.2(f), the Borrowing Base shall automatically reduce by 75% of the principal amount of such Debt.

The Borrower acknowledges that the determination of the Borrowing Base contains an equity cushion (market value in excess of loan value), which is acknowledged by Borrower to be essential for the adequate protection of the Agent and the Banks. (g) The Borrower shall also have the right to reduce the Borrowing Base once during the period from October 1 to March 31 and once during the period from April 1 to September 30 during each year by providing the Agent 30 days advance written notice of such reduction.

(c) Certain Limitations. Notwithstanding anything in paragraphs (a) and (b) above: (i) at no time shall there be more than eight Interest Periods applicable to outstanding Eurodollar Rate Advances; (ii) if any Bank shall, at least one Business Day before the date of any requested Borrowing, Conversion, or continuation, notify the Agent that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful, for such Bank or its Eurodollar Lending Office to perform its obligations under this Agreement to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances, the right of the Borrower to select Eurodollar Rate Advances from such Bank shall be suspended until such Bank shall notify the Agent that the circumstances causing such suspension no longer exist, and the Advance made by such Bank in respect of such Borrowing, Conversion, or continuation shall be a Base Rate Advance; (iii) if the Agent is unable to determine the Eurodollar Rate for Eurodollar Rate Advances comprising any requested Borrowing, the right of the Borrower to select Eurodollar Rate Advances for such Borrowing or for any subsequent Borrowing shall be suspended until the Agent shall notify the Borrower and the Banks that the circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be a Base Rate Advance; (iv) if the Majority Banks shall, at least one Business Day before the date of any requested Borrowing, notify the Agent that the Eurodollar Rate for Eurodollar Rate Advances comprising such Borrowing will not adequately reflect the cost to such Banks of making or funding their respective Eurodollar Rate Advances, as the case may be, for such Borrowing, the right of the Borrower to select Eurodollar Rate Advances for such Borrowing or for any subsequent Borrowing shall be suspended until the Agent shall notify the Borrower and the Banks that the circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be a Base Rate Advance; and -16- (v) if the Borrower shall fail to select the duration or continuation of any Interest Period for any Eurodollar Rate Advances in accordance with the provisions contained in the definition of "Interest Period" in Section 1.1 and paragraph (b) above, the Agent shall forthwith so notify the Borrower and the Banks and such Advances shall be made available to the Borrower on the date of such Borrowing as Base Rate Advances or, if an existing Advance, Convert into Base Rate Advances. (d) Notices Irrevocable. Each Notice of Borrowing and Notice of Conversion or Continuation shall be irrevocable and binding on the Borrower. In the case of any Borrowing which the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower shall indemnify each Bank against any loss, out-of-pocket cost, or expense incurred by such Bank as a result of any failure by the Borrower to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article III including, without limitation, any loss (including any loss of anticipated profits), cost, or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Bank to fund the Advance to be made by such Bank as part of such Borrowing when such Advance, as a result of such failure, is not made on such date. (e) Agent Reliance. Unless the Agent shall have received notice from a Bank before the date of any Borrowing that such Bank shall not make available to the Agent such Bank's Pro Rata Share of such Borrowing, the Agent may assume that such Bank has made its Pro Rata Share of such Borrowing available to the Agent on the date of such Borrowing in accordance with paragraph (a) of this Section 2.3 and the Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Bank shall not have so made its Pro Rata Share of such Borrowing available to the Agent, such Bank and the Borrower severally agree to immediately repay to the Agent on demand such corresponding amount, together with interest on such amount, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Agent, at (i) in the case of the Borrower, the interest rate applicable on such day to Advances comprising such Borrowing and (ii) in the case of such Bank, the Federal Funds Rate for such day. If such Bank shall repay to the Agent such corresponding amount and interest as provided above, such corresponding amount so repaid shall constitute such Bank's Advance as part of such Borrowing for purposes of this Agreement even though not made on the same day as the other Advances comprising such Borrowing. (f) Bank Obligations Several. The failure of any Bank to make the Advance to be made by it as part of any Borrowing shall not relieve any other Bank of its obligation, if any, to make its Advance on the date of such Borrowing. No Bank shall be responsible for the failure of any other Bank to make the Advance to be made by such other Bank on the date of any Borrowing. Section 2.4. Prepayment of Advances. (a) Optional.

Any amount paid under the preceding sentence in respect of Letter of Credit Exposure and Existing Letter of Credit Exposure shall be held as cash collateral under Section 2.6(g). Each prepayment pursuant to this Section 2.4(c) shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.11 as a result of such prepayment being made on such date. (d) Asset Sales; Debt Issuances. (i) If, after giving effect to the sale, transfer or other disposition of any of the Borrower's or any of its Subsidiaries' Oil and Gas Properties, the aggregate outstanding amount of Advances plus the Letter of Credit Exposure plus the Existing Letter of Credit Exposure exceeds the Borrowing Base, the Borrower shall repay the Advances by an amount equal to such Borrowing Base deficiency, upon receipt of the proceeds of such sale, transfer, or other disposition, whether at closing of such sale, transfer, or other disposition or thereafter and (ii) upon the issuance of any Debt permitted under Section 6.2(f), the Borrower shall prepay the Advances by an amount equal to the net cash proceeds received from such Debt issuance.

(e) Illegality. If any Bank shall notify the Agent and the Borrower that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or that any central bank or other governmental authority asserts that it is unlawful for such Bank or its Eurodollar Lending Office to perform its obligations under this Agreement to maintain any Eurodollar Rate Advances of such Bank then outstanding hereunder, (i) the Borrower shall, no later than 10:00 a.m. (Dallas, Texas, time) (A) if not prohibited by law, on the last day of the Interest Period for each outstanding Eurodollar Rate Advance made by such Bank or (B) if required by such notice, on the second Business Day following its receipt of such notice prepay all of the Eurodollar Rate Advances made by such Bank then outstanding, together with accrued interest on the principal amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.11 as a result of such prepayment being made on such date, (ii) such Bank shall simultaneously make a Base Rate Advance to the Borrower on such date in an amount equal to the aggregate principal amount of the Eurodollar Rate Advances prepaid to such Bank, and (iii) the right of the Borrower to select Eurodollar Rate Advances from such Bank for any subsequent Borrowing shall be suspended until such Bank gives notice referred to above shall notify the Agent that the circumstances causing such suspension no longer exist.

No Letter of Credit shall be issued, increased, or extended and no Existing Letters of Credit shall convert to Letters of Credit: (i) unless such issuance, increase, extension or conversion would not cause the Letter of Credit Exposure plus the Existing Letter of Credit Exposure to exceed the lesser of (A) $50,000,000.00 or (B) the lesser of (1) the aggregate Commitments less the aggregate outstanding principal amount of all Advances or (2) the Borrowing Base less the aggregate outstanding principal amount of all Advances; (ii) unless such Letter of Credit has an Expiration Date not later than the earlier of (A) 12 months after the date of issuance thereof (or, if extendable beyond such period, unless such Letter of Credit is cancelable upon at least 30 days' notice given by the Issuing Bank to the beneficiary of such Letter of Credit) or (B) the Maturity Date; (iii) unless such Letter of Credit Documents are in form and substance acceptable to the Issuing Bank in its sole discretion; (iv) unless such Letter of Credit is a standby letter of credit not supporting the repayment of indebtedness for borrowed money of any Person; and (v) unless the Borrower has delivered to the Issuing Bank a completed and executed Letter of Credit Application.

Upon such notice from the Agent, each Bank shall promptly reimburse the Issuing Bank for such Bank's Pro Rata Share of such amount, and such reimbursement shall be deemed for all purposes of this Agreement to be a Advance to the Borrower transferred at the Borrower's request to the Issuing Bank.

The Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Agent and the Banks to record and otherwise treat such reimbursements to the Issuing Bank as Base Rate Advances under a Borrowing requested by the Borrower to reimburse the Issuing Bank which have been transferred to the Issuing Bank at the Borrower's request.

(f) Liability of Issuing Bank. The Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. Neither the Issuing Bank nor any of its officers or directors shall be liable or responsible for: (i) the use which may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith; (ii) the validity, sufficiency, or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent, or forged; (iii) payment by the Issuing Bank against presentation of documents which do not comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to the relevant Letter of Credit; or (iv) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit (INCLUDING THE ISSUING BANK'S OWN NEGLIGENCE), except that the Borrower shall have a claim against the Issuing Bank, and the Issuing Bank shall be liable to the Borrower, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower which the Borrower proves were caused by (A) the Issuing Bank's willful misconduct or gross negligence in determining whether documents presented under a Letter of Credit comply with the terms of such Letter of Credit or (B) the Issuing Bank's willful failure to make lawful payment under any Letter of Credit after the presentation to it of a draft and certificate strictly complying with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, the Issuing Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary. (g) Cash Collateral Account. (i) If the Borrower is required to deposit funds in the Cash Collateral Account pursuant to Sections 2.4(b) or (c), 7.2(b), or 7.3(b), then the Borrower and the Agent shall establish the Cash Collateral Account and the Borrower shall execute any documents and agreements, including the Agent's standard form assignment of deposit accounts, that the Agent requests in connection therewith to establish the Cash Collateral Account and grant the Agent a first priority security interest in such account and the funds therein. The Borrower hereby pledges to the Agent and grants the Agent a security interest in the Cash Collateral Account, whenever established, all funds held in the Cash Collateral Account from time to time, and all proceeds thereof as security for the payment of the Obligations. -22- (ii) So long as no Event of Default exists, (A) the Agent may apply the funds held in the Cash Collateral Account only to the reimbursement of any Letter of Credit Obligations, and (B) the Agent shall release to the Borrower at the Borrower's written request any funds held in the Cash Collateral Account in an amount up to but not exceeding the excess, if any (immediately prior to the release of any such funds), of the total amount of funds held in the Cash Collateral Account over the Letter of Credit Exposure. During the existence of any Event of Default, the Agent may apply any funds held in the Cash Collateral Account to the Obligations in any order determined by the Agent, regardless of any Letter of Credit Exposure which may remain outstanding. The Agent may in its sole discretion at any time release to the Borrower any funds held in the Cash Collateral Account. (iii) The Agent shall exercise reasonable care in the custody and preservation of any funds held in the Cash Collateral Account and shall be deemed to have exercised such care if such funds are accorded treatment substantially equivalent to that which the Agent accords its own property, it being understood that the Agent shall not have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any such funds. Section 2.7. Fees. (a) Commitment Fees. (i) The Borrower agrees to pay to the Agent for the account of each Bank a commitment fee per annum equal to the Applicable Margin for commitment fees in effect from time to time on the average daily amount by which such Bank's Pro Rata Share of the Borrowing Base exceeds the sum of such Bank's outstanding Advances and such Bank's Pro Rata Share of the Letter of Credit Exposure, from the Effective Date until the Maturity Date. (ii) The commitment fees shall be due and payable quarterly in arrears on the last day of each March, June, September, and December during the term of this Agreement and on the Maturity Date. (b) Agent Fees. The Borrower agrees to pay to the Agent for the benefit of the Agent the fees described in the letter dated November 5, 2001, from the Agent to the Borrower (the "Agent's Fee Letter"). (c) Bank Fees. The Borrower agrees to pay to the Agent for the ratable benefit of the Banks on the Effective Date, the fees agreed to between the Borrower and the Banks. (d) Letter of Credit Fees. The Borrower agrees to pay (i) to the Agent for the pro rata benefit of the Banks a per annum fee for each Letter of Credit issued hereunder equal to the Applicable Margin for Eurodollar Advances on the face amount of such Letter of Credit, but with minimum annual fee of $500.00 on each Letter of Credit and (ii) to the Agent for the benefit of the Issuing Bank a fee for each Letter of Credit equal to 0.125% per annum of the face amount of such Letter of Credit. Each such fee shall be payable quarterly in arrears after the date of the -23- issuance, increase or extension of the Letter of Credit, but, in the case of an increase or extension only, on the amount of such increase or for the period of such extension. Section 2.8. Interest. The Borrower shall pay interest on the unpaid principal amount of each Advance made by each Bank from the date of such Advance until such principal amount shall be paid in full, at the following rates per annum: (a) Base Rate Advances. If such Advance is a Base Rate Advance, a rate per annum equal at all times to the Adjusted Base Rate in effect from time to time plus the Applicable Margin in effect from time to time, payable in arrears on the last day of March, June, September, and December and on the date such Base Rate Advance shall be paid in full, provided that any amount of principal which is not paid when due (whether at stated maturity, by acceleration, or otherwise) shall bear interest from the date on which such amount is due until such amount is paid in full, payable on demand, at a rate per annum equal at all times to the Adjusted Base Rate in effect from time to time plus the Applicable Margin plus 2.00% per annum. (b) Eurodollar Rate Advances. If such Advance is a Eurodollar Rate Advance, a rate per annum equal at all times during the Interest Period for such Advance to the Eurodollar Rate for such Interest Period plus the Applicable Margin in effect from time to time, payable on the last day of such Interest Period, and, in the case of six-month Interest Periods, on the day which occurs during such Interest Period three months from the first day of such Interest Period, provided that any amount of principal which is not paid when due (whether at stated maturity, by acceleration, or otherwise) shall bear interest from the date on which such amount is due until such amount is paid in full, payable on demand, at a rate per annum equal at all times to the Adjusted Base Rate in effect from time to time plus the Applicable Margin plus 2.00% per annum. (c) Additional Interest on Eurodollar Rate Advances. The Borrower shall pay to each Bank, so long as any such Bank shall be required under regulations of the Federal Reserve Board to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of each Eurodollar Rate Advance of such Bank, from the effective date of such Advance until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (A) the Eurodollar Rate for the Interest Period for such Advance from (B) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Bank for such Interest Period, payable on each date on which interest is payable on such Advance. Such additional interest payable to any Bank shall be determined by such Bank and notified to the Borrower through the Agent (such notice to include the calculation of such additional interest, which calculation shall be conclusive in the absence of manifest error). (d) Usury. (i) If, with respect to any Bank, the effective rate of interest contracted for under the Credit Documents, including the stated rates of interest and fees contracted for hereunder and any other amounts contracted for under the Credit Documents which are deemed to be interest, at any time exceeds the Maximum Rate, then the outstanding -24- principal amount of the loans made by such Bank hereunder shall bear interest at a rate which would make the effective rate of interest for such Bank under the Credit Documents equal the Maximum Rate until the difference between the amounts which would have been due at the stated rates and the amounts which were due at the Maximum Rate (the "Lost Interest") has been recaptured by such Bank. (ii) If, when the loans made hereunder are repaid in full, the Lost Interest has not been fully recaptured by such Bank pursuant to the preceding paragraph, then, to the extent permitted by law, for the loans made hereunder by such Bank the interest rates charged under Section 2.8 hereunder shall be retroactively increased such that the effective rate of interest under the Credit Documents was at the Maximum Rate since the effectiveness of this Agreement to the extent necessary to recapture the Lost Interest not recaptured pursuant to the preceding sentence and, to the extent allowed by law, the Borrower shall pay to such Bank the amount of the Lost Interest remaining to be recaptured by such Bank. (iii) NOTWITHSTANDING the foregoing or any other term in this Agreement and the Credit Documents to the contrary, it is the intention of each Bank and the Borrower to conform strictly to any applicable usury laws. Accordingly, if any Bank contracts for, charges, or receives any consideration which constitutes interest in excess of the Maximum Rate, then any such excess shall be canceled automatically and, if previously paid, shall at such Bank's option be applied to the outstanding amount of the loans made hereunder by such Bank or be refunded to the Borrower. Section 2.9. Payments and Computations. (a) Payment Procedures. The Borrower shall make each payment under this Agreement and under the Notes not later than 10:00 a.m. (Dallas, Texas, time) on the day when due in Dollars to the Agent at 901 Main Street, 49th Floor, Dallas, Texas 75202 (or such other location as the Agent shall designate in writing to the Borrower), in same day funds. The Agent shall promptly thereafter cause to be distributed like funds relating to the payment of principal, interest or fees ratably (other than amounts payable solely to the Agent, the Issuing Bank, or a specific Bank pursuant to Section 2.7(b), 2.8(c), 2.11, 2.12, 2.13, 8.5, or 9.7, but after taking into account payments effected pursuant to Section 9.4) to the Banks for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Bank or the Issuing Bank to such Bank for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. (b) Computations. All computations of interest based on the Base Rate shall be made by the Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate and the Federal Funds Rate and of fees shall be made by the Agent, on the basis of a year of 360 days, in each case for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Agent of an interest rate or fee shall be conclusive and binding for all purposes, absent manifest error. -25- (c) Non-Business Day Payments. Whenever any payment shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided, however, that if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day. (d) Agent Reliance. Unless the Agent shall have received written notice from the Borrower prior to the date on which any payment is due to the Banks that the Borrower shall not make such payment in full, the Agent may assume that the Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such date an amount equal to the amount then due such Bank. If and to the extent the Borrower shall not have so made such payment in full to the Agent, each Bank shall repay to the Agent forthwith on demand such amount distributed to such Bank, together with interest, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Agent, at the Federal Funds Rate for such day. Section 2.10. Sharing of Payments, Etc. If any Bank shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Advances or Letter of Credit Obligations made by it in excess of its Pro Rata Share of payments on account of the Advances or Letter of Credit Obligations obtained by all the Banks, such Bank shall notify the Agent and forthwith purchase from the other Banks such participations in the Advances made by them or Letter of Credit Obligations held by them as shall be necessary to cause such purchasing Bank to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Bank, such purchase from each Bank shall be rescinded and such Bank shall repay to the purchasing Bank the purchase price to the extent of such Bank's ratable share (according to the proportion of (a) the amount of the participation sold by such Bank to the purchasing Bank as a result of such excess payment to (b) the total amount of such excess payment) of such recovery, together with an amount equal to such Bank's ratable share (according to the proportion of (a) the amount of such Bank's required repayment to the purchasing Bank to (b) the total amount of all such required repayments to the purchasing Bank) of any interest or other amount paid or payable by the purchasing Bank in respect of the total amount so recovered. The Borrower agrees that any Bank so purchasing a participation from another Bank pursuant to this Section 2.10 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Bank were the direct creditor of the Borrower in the amount of such participation. Section 2.11. Breakage Costs. If (a) any payment of principal of any Eurodollar Rate Advance is made other than on the last day of the Interest Period for such Advance, whether as a result of any payment pursuant to Section 2.4, the acceleration of the maturity of the Notes pursuant to Article VII, or otherwise, or (b) the Borrower fails to make a principal or interest payment with respect to any Eurodollar Rate Advance on the date such payment is due and payable, the Borrower shall, within 10 days of any written demand sent by any Bank to the Borrower through the Agent, pay to the Agent for the account of such Bank any amounts required to compensate such Bank for any additional losses, out-of-pocket costs or expenses which it may reasonably incur as a result of such payment or nonpayment, including, without -26- limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Bank to fund or maintain such Advance. Section 2.12. Increased Costs. (a) Eurodollar Rate Advances. If, due to either (i) the introduction of or any change (other than any change by way of imposition or increase of reserve requirements included in the Eurodollar Rate Reserve Percentage) in or in the interpretation of any law or regulation or (ii) the compliance with any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law), there shall be any increase in the cost to any Bank of agreeing to make or making, funding, or maintaining Eurodollar Rate Advances, then the Borrower shall from time to time, upon demand by such Bank (with a copy of such demand to the Agent), immediately pay to the Agent for the account of such Bank additional amounts sufficient to compensate such Bank for such increased cost. A certificate as to the amount of such increased cost and detailing the calculation of such cost submitted to the Borrower and the Agent by such Bank shall be conclusive and binding for all purposes, absent manifest error. (b) Capital Adequacy. If any Bank or the Issuing Bank determines in good faith that compliance with any law or regulation or any guideline or request from any central bank or other governmental authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Bank or the Issuing Bank or any corporation controlling such Bank or the Issuing Bank and that the amount of such capital is increased by or based upon the existence of such Bank's commitment to lend or the Issuing Bank's commitment to issue the Letters of Credit and other commitments of this type, then, upon 30 days' prior written notice by such Bank or the Issuing Bank (with a copy of any such demand to the Agent), the Borrower shall immediately pay to the Agent for the account of such Bank or to the Issuing Bank, as the case may be, from time to time as specified by such Bank or the Issuing Bank, additional amounts sufficient to compensate such Bank or the Issuing Bank, in light of such circumstances, (i) with respect to such Bank, to the extent that such Bank reasonably determines such increase in capital to be allocable to the existence of such Bank's commitment to lend under this Agreement and (ii) with respect to the Issuing Bank, to the extent that the Issuing Bank reasonably determines such increase in capital to be allocable to the issuance or maintenance of the Letters of Credit for such increased cost. A certificate as to such amounts and detailing the calculation of such amounts submitted to the Borrower by such Bank or the Issuing Bank shall be conclusive and binding for all purposes, absent manifest error. (c) Letters of Credit. If any change in any law or regulation or in the interpretation thereof by any court or administrative or Governmental Authority charged with the administration thereof shall either (i) impose, modify, or deem applicable any reserve, special deposit, or similar requirement against letters of credit issued by, or assets held by, or deposits in or for the account of, the Issuing Bank or (ii) impose on the Issuing Bank any other condition regarding the provisions of this Agreement relating to the Letters of Credit or any Letter of Credit Obligations, and the result of any event referred to in the preceding clause (i) or (ii) shall be to increase the cost to the Issuing Bank of issuing or maintaining any Letter of Credit (which increase in cost shall be determined by the Issuing Bank's reasonable allocation of the aggregate of such cost increases resulting from such event), then, upon demand by the Issuing Bank, the -27- Borrower shall pay to the Issuing Bank, from time to time as specified by the Issuing Bank, additional amounts which shall be sufficient to compensate the Issuing Bank for such increased cost. A certificate as to such increased cost incurred by the Issuing Bank, as a result of any event mentioned in clause (i) or (ii) above, and detailing the calculation of such increased costs submitted by the Issuing Bank to the Borrower, shall be conclusive and binding for all purposes, absent manifest error. Section 2.13. Taxes. (a) No Deduction for Certain Taxes. Any and all payments by the Borrower shall be made, in accordance with Section 2.9, 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 Bank, the Issuing Bank, and the Agent, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction under the laws of which such Bank, the Issuing Bank, or the Agent (as the case may be) is organized or any political subdivision of the jurisdiction (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as "Taxes") and, in the case of each Bank and the Issuing Bank, Taxes by the jurisdiction of such Bank's Applicable Lending Office or any political subdivision of such jurisdiction. If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable to any Bank, the Issuing Bank, or the Agent, (i) the sum payable shall be increased as may be necessary so that, after making all required deductions (including deductions applicable to additional sums payable under this Section 2.13), such Bank, the Issuing Bank, or the Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made; provided, however, that if the Borrower's obligation to deduct or withhold Taxes is caused solely by such Bank's, the Issuing Bank's, or the Agent's failure to provide the forms described in paragraph (d) of this Section 2.13 and such Bank, the Issuing Bank, or the Agent could have provided such forms, no such increase shall be required; (ii) the Borrower shall make such deductions; and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law. (b) Other Taxes. In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made or from the execution, delivery or registration of, or otherwise with respect to, this Agreement, the Notes, or the other Credit Documents (hereinafter referred to as "Other Taxes"). (c) Indemnification. THE BORROWER INDEMNIFIES EACH BANK, THE ISSUING BANK, AND THE AGENT FOR THE FULL AMOUNT OF TAXES OR OTHER TAXES (INCLUDING, WITHOUT LIMITATION, ANY TAXES OR OTHER TAXES IMPOSED BY ANY JURISDICTION ON AMOUNTS PAYABLE UNDER THIS SECTION 2.13) PAID BY SUCH BANK, THE ISSUING BANK, OR THE AGENT (AS THE CASE MAY BE) AND ANY LIABILITY (INCLUDING INTEREST AND EXPENSES) ARISING THEREFROM OR WITH RESPECT THERETO, WHETHER OR NOT SUCH TAXES OR OTHER TAXES WERE CORRECTLY OR LEGALLY ASSERTED. EACH PAYMENT REQUIRED TO BE MADE BY THE BORROWER IN RESPECT OF THIS INDEMNIFICATION SHALL BE MADE TO THE AGENT FOR THE BENEFIT OF ANY -28- PARTY CLAIMING SUCH INDEMNIFICATION WITHIN 30 DAYS FROM THE DATE THE BORROWER RECEIVES WRITTEN DEMAND THEREFOR FROM THE AGENT ON BEHALF OF ITSELF AS AGENT, THE ISSUING BANK, OR ANY SUCH BANK. IF ANY BANK, THE AGENT, OR THE ISSUING BANK RECEIVES A REFUND IN RESPECT OF ANY TAXES PAID BY THE BORROWER UNDER THIS PARAGRAPH (C), SUCH BANK, THE AGENT, OR THE ISSUING BANK, AS THE CASE MAY BE, SHALL PROMPTLY PAY TO THE BORROWER THE BORROWER'S SHARE OF SUCH REFUND. (d) Foreign Bank Withholding Exemption. Each Bank and Issuing Bank that is not incorporated under the laws of the United States of America or a state thereof agrees that it will deliver to the Borrower and the Agent on the date of this Agreement or upon the effectiveness of any Assignment and Acceptance and from time to time thereafter if requested in writing by the Borrower (i) Internal Revenue Service Form W-8ECI, W-8BEN, W-8EXP, or W-8IMY as appropriate, or any successor form prescribed by the Internal Revenue Service, certifying that such Bank is entitled to benefits under an income tax treaty to which the United States is a party which exempts such Bank from withholding tax on payments of interest or certifying that the income receivable pursuant to this Agreement is effectively connected with the conduct of a trade or business in the United States, (ii) Internal Revenue Service Form W-9, as appropriate, or any successor form prescribed by the Internal Revenue Service, and (iii) any other form or certificate required by any taxing authority (including any certificate required by Sections 871(h) and 881(c) of the Internal Revenue Code), certifying that such Bank is entitled to an exemption from tax on payments pursuant to this Agreement or any of the other Credit Documents If an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any delivery required by the preceding sentence would otherwise be required which renders all such forms inapplicable or which would prevent any Bank from duly completing and delivering any such letter or form with respect to it and such Bank advises the Borrower and the Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax, and, in the case of a Form W-9, establishing an exemption from United States backup withholding tax, such Bank shall not be required to deliver such letter or forms.

All factual information (excluding estimates) heretofore or contemporaneously furnished by or on behalf of the Borrower or any of its Subsidiaries in writing to any Bank or the Agent for purposes of or in connection with this Agreement, any other Credit Document or any transaction contemplated hereby or thereby is (taken as a whole) true and accurate in all material respects on the date as of which such information is dated or certified and does not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements contained therein not misleading as of the date of this Agreement. All projections, estimates, and pro forma financial information furnished by the Borrower were prepared on the basis of assumptions, data, information, tests, or conditions believed to be reasonable at the time such projections, estimates, and pro forma financial information were furnished. Section 4.7. Litigation. Set forth on Schedule 4.7 is an accurate description of all of the Borrower's and its Subsidiaries' pending litigation existing on the date of this Agreement which could reasonably be expected to cause a Material Adverse Change. There is no pending or, to the best knowledge of the Borrower, threatened action or proceeding affecting the Borrower or any of its Subsidiaries before any court, Governmental Agency or arbitrator, which could reasonably be expected to cause a Material Adverse Change or which purports to affect the legality, validity, binding effect, or enforceability of this Agreement, any Note, or any other Credit Document. Section 4.8. Use of Proceeds. All Advances and Letters of Credit shall be used to finance the acquisition of oil and gas reserves and for general corporate purposes of the Borrower and its Subsidiaries, but in no event for the payment of dividends or other distributions or advances to the shareholders of the Borrower. The Borrower is not engaged in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of -33- Regulation U). No proceeds of any Advance will be used to purchase or carry any margin stock in violation of Regulation T, U or X. Section 4.9. Investment Company Act. Neither the Borrower nor any of its Subsidiaries is an "investment company" or a company "controlled" by an "investment company" within the meaning of the Investment Company Act of 1940, as amended. Section 4.10. Public Utility Holding Company Act. Neither the Borrower nor any of its Subsidiaries is a "holding company," or a "Subsidiary company" of a "holding company," or an "affiliate" of a "holding company" or of a "Subsidiary company" of a "holding company," within the meaning of the Public Utility Holding Company Act of 1935, as amended. Section 4.11. Taxes. Proper and accurate (in all material respects) federal, state, local, and foreign tax returns, reports and statements required to be filed (after giving effect to any extension granted in the time of filing) by or on behalf of the Borrower, its Subsidiaries, or any member of the Controlled Group (hereafter collectively called the "Tax Group") have been duly filed on a timely basis or appropriate extensions have been obtained with appropriate governmental agencies in all jurisdictions in which such returns, reports, and statements are required to be filed, except where the failure to so file would not be reasonably expected to cause a Material Adverse Change; and all taxes (which are material in amount) and other impositions due and payable have been timely paid prior to the date on which any fine, penalty, interest, late charge, or loss may be added thereto for non-payment thereof, except where contested in good faith by appropriate proceedings. The reserves for accrued taxes reflected in the financial statements delivered to the Banks under this Agreement are adequate in the aggregate for the payment of all unpaid taxes, whether or not disputed, for the period ended as of the date thereof and for any period prior thereto, and for which the Tax Group may be liable in its own right, as withholding agent or as a transferee of the assets of, or successor to, any Person, except for such taxes or reserves therefor, the failure to pay or provide for which does not and could not cause a Material Adverse Change. Timely payment of all material sales and use taxes required by applicable law has been made by the Borrower and all other members of the Tax Group. Section 4.12. Pension Plans. All Plans are in compliance in all material respects with all applicable provisions of ERISA. No Termination Event has occurred with respect to any Plan, and each Plan has complied with and been administered in all material respects with applicable provisions of ERISA and the Code. No "accumulated funding deficiency" (as defined in Section 302 of ERISA) has occurred and there has been no excise tax imposed under Section 4971 of the Code. No Reportable Event has occurred with respect to any Multiemployer Plan, and each Multiemployer Plan has complied with and been administered in all material respects with applicable provisions of ERISA and the Code. The present value of all benefits vested under each Plan (based on the assumptions used to fund such Plan) did not, as of the last annual valuation date applicable thereto, exceed the value of the assets of such Plan allocable to such vested benefits. Neither the Borrower nor any member of the Controlled Group has had a complete or partial withdrawal from any Multiemployer Plan for which there is any withdrawal liability. As of the most recent valuation date applicable thereto, neither the Borrower nor any member of the Controlled Group would become subject to any liability under ERISA if the Borrower or any member of the Controlled Group has received notice that any Multiemployer Plan is insolvent or in reorganization. Based upon GAAP existing as of the date of this -34- Agreement and current factual circumstances, the Borrower has no reason to believe that the annual cost during the term of this Agreement to the Borrower or any member of the Controlled Group for post-retirement benefits to be provided to the current and former employees of the Borrower or any member of the Controlled Group under Plans that are welfare benefit plans (as defined in Section 3(a) of ERISA) could, in the aggregate, reasonably be expected to cause a Material Adverse Change. Section 4.13. Condition of Property; Casualties. The Borrower and each of the Guarantors has good and indefeasible title to all of its Properties as is customary in the oil and gas industry in all material respects, free and clear of all Liens except for Permitted Liens. The material Properties used or to be used in the continuing operations of the Borrower and each of its Subsidiaries are in good repair, working order and condition. Since the date of the Financial Statements, neither the business nor the material properties of the Borrower and each of its Subsidiaries, taken as a whole, has 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 a Governmental Authority, riot, activities of armed forces, or acts of God or of any public enemy. Section 4.14. No Burdensome Restrictions; No Defaults. Neither the Borrower nor any of its Subsidiaries is a party to any indenture, loan, or credit agreement or any lease or other agreement or instrument or subject to any charter or corporate restriction or provision of applicable law or governmental regulation which could reasonably be expected to cause a Material Adverse Change. The Borrower and the Guarantors are not in default under or with respect to any contract, agreement, lease, or other instrument to which the Borrower or any Guarantor is a party and which could reasonably be expected to cause a Material Adverse Change. Neither the Borrower nor any Guarantor has received any notice of default under any material contract, agreement, lease, or other instrument to which the Borrower or such Guarantor is a party. No Default has occurred and is continuing. Section 4.15. Environmental Condition. (a) Permits, Etc. Except as set forth on Schedule 4.15(a), the Borrower and its Subsidiaries (i) have obtained all Environmental Permits necessary for the ownership and operation of their respective Properties and the conduct of their respective businesses; (ii) have been and are in material compliance with all terms and conditions of such Environmental Permits and with all other material requirements of applicable Environmental Laws; (iii) have not received notice of any material violation or alleged violation of any Environmental Law or Environmental Permit; and (iv) are not subject to any actual or contingent Environmental Claim, which could reasonably be expected to cause a Material Adverse Change. (b) Certain Liabilities. Except as set forth on Schedule 4.15(b), to the Borrower's actual knowledge, none of the present or previously owned or operated Property of the Borrower or of any of its present or former Subsidiaries, wherever located, (i) has been placed on or proposed to be placed on the National Priorities List, the Comprehensive Environmental Response Compensation Liability Information System list, or their state or local analogs, or have been otherwise investigated, designated, listed, or identified as a potential site for removal, -35- remediation, cleanup, closure, restoration, reclamation, or other response activity under any Environmental Laws; (ii) is subject to a Lien, arising under or in connection with any Environmental Laws, that attaches to any revenues or to any Property owned or operated by the Borrower or any of its Subsidiaries, wherever located, which could reasonably be expected to cause a Material Adverse Change; or (iii) has been the site of any Release of Hazardous Substances or Hazardous Wastes from present or past operations which has caused at the site or at any third-party site any condition that has resulted in or could reasonably be expected to result in the need for Response that would cause a Material Adverse Change. (c) Certain Actions. Without limiting the foregoing, (i) all necessary notices have been properly filed, and no further action is required under current Environmental Law as to each Response or other restoration or remedial project undertaken by the Borrower, or its present or former Subsidiaries on any of their presently or formerly owned or operated Property and (ii) the present and, to the Borrower's best knowledge, future liability, if any, of the Borrower and its Subsidiaries which could reasonably be expected to arise in connection with requirements under Environmental Laws will not result in a Material Adverse Change. Section 4.16. Permits, Licenses, Etc. The Borrower and its Subsidiaries possess all permits, licenses, patents, patent rights or licenses, trademarks, trademark rights, trade names rights and copyrights which are material to the conduct of its business. The Borrower and its Subsidiaries manage and operate their business in all material respects in accordance with all applicable Legal Requirements and good industry practices. Section 4.17. Gas Contracts. Neither the Borrower nor any of its Subsidiaries, as of the date hereof, (a) is obligated in any material respect by virtue of any prepayment made under any contract containing a "take-or-pay" or "prepayment" provision or under any similar agreement to deliver hydrocarbons produced from or allocated to any of the Borrower's consolidated Oil and Gas Properties at some future date without receiving full payment therefor at the time of delivery, or (b) has produced gas, in any material amount, subject to, and none of the Borrower's consolidated Oil and Gas Properties is subject to, balancing rights of third parties or subject to balancing duties under governmental requirements, except as to such matters for which the Borrower or its relevant Subsidiary has established monetary reserves adequate in amount in accordance with GAAP to satisfy such obligations.

Section 5.3. Preservation of Corporate Existence, Etc. The Borrower shall preserve and maintain, and cause each of its Subsidiaries to preserve and maintain, its corporate existence, rights, franchises, and privileges in the jurisdiction of its incorporation, and qualify and remain qualified, and cause each such Subsidiary to qualify and remain qualified, as a foreign corporation in each jurisdiction in which qualification is necessary or desirable in view of its business and operations or the ownership of its properties, and, in each case, where failure to qualify or preserve and maintain its rights and franchises could reasonably be expected to cause a Material Adverse Change; provided, however, that nothing herein contained shall prevent any transaction permitted by Section 6.4. Section 5.4. Payment of Taxes, Etc. The Borrower shall pay and discharge, and cause each of its Subsidiaries to pay and discharge, before the same shall become delinquent, (a) all taxes, assessments, and governmental charges or levies imposed upon it or upon its income or profits or Property that are material in amount, prior to the date on which penalties attach thereto and (b) all lawful claims that are material in amount which, if unpaid, might by law become a Lien upon its Property; provided, however, that neither the Borrower nor any such Subsidiary shall be required to pay or discharge any such tax, assessment, charge, levy, or claim which is being contested in good faith and by appropriate proceedings, and with respect to which reserves in conformity with GAAP have been provided. Section 5.5. Visitation Rights. At any reasonable time and from time to time, upon reasonable notice, the Borrower shall, and shall cause its Subsidiaries to, permit the Agent and any Bank or any of its agents or representatives thereof, to (a) examine and make copies of and abstracts from the records and books of account of, and visit and inspect at its reasonable discretion the properties of, the Borrower and any such Subsidiary, and (b) discuss the affairs, finances and accounts of the Borrower and any such Subsidiary with any of their respective officers or directors; provided however, the Agent or the Bank for whose benefit such inspection and visitation is made assumes sole responsibility for the condition of any property of the Borrower or its Subsidiaries so visited and inspected, the access and egress thereto (including, but not limited to wharves, docks, and helicopter landing areas), and any vice or defect therein or thereon, and assumes all responsibility for and hereby releases and indemnifies the Borrower, its Affiliates, and their officers, directors, employees, and agents against any claim for damage or injury to or by the Agent or such Bank (or the representatives thereof) or to the Borrower's or its -37- Subsidiaries' property which may be occasioned by such inspection and visitation of the Borrower's or its Subsidiaries' property.

Section 5.8. New Subsidiaries. Upon the creation or acquisition of any Material Subsidiary after the date of this Agreement or if an existing Subsidiary becomes a Material Subsidiary after the date of this Agreement, the Borrower shall cause such Subsidiary to execute and deliver to the Agent (a) a Guaranty with such changes as the Agent may reasonably request -40- and (b) evidence of corporate authority to enter into such Guaranty as the Agent may reasonably request, including, without limitation, a legal opinion regarding the enforceability of such Guaranty; except that Conoco Offshore Inc. or its successor shall not be required to execute and deliver a Guaranty until March 15, 2002.

Section 6.5. Restricted Payments. The Borrower shall not, and shall not permit any of its Subsidiaries to, make or pay any Restricted Payment other than Restricted Payments from a Subsidiary of the Borrower to the Borrower.

Section 6.9. Compliance with ERISA.
