In valuing and redetermining the Borrowing Base, the Administrative Agent and the Lenders may also consider the business, financial condition, and Debt obligations of the Borrower and its relevant Subsidiaries and such other factors as the Administrative Agent and the Lenders customarily deem appropriate. In that regard, the Borrower acknowledges that the determination of the Borrowing Base contains an equity cushion (market value in excess of loan value), which is essential for the adequate protection of the Administrative Agent and the Lenders. No Proven Reserves shall be included or considered for inclusion in the Borrowing Base unless the Administrative Agent and the Lenders shall have received, at the Borrower's expense, evidence of title satisfactory in form and substance to the Administrative Agent that the Administrative Agent has an Acceptable Security Interest in the Oil and Gas Properties relating thereto pursuant to the Security Instruments. At all times after the Administrative Agent has given the Borrower notification of a redetermination of the Borrowing Base under this Section 2.02, the Borrowing Base shall be equal to the redetermined amount or such lesser amount designated by the Borrower and disclosed in writing to the Administrative Agent and the Lenders until the Borrowing Base is subsequently redetermined in accordance with this Section 2.02. Section 2.03 Method of Borrowing. (a) Notice. Each Borrowing shall be made pursuant to a Notice of Borrowing (or by telephone notice promptly confirmed in writing by a Notice of Borrowing), given not later than 10:00 a.m. (Dallas, Texas time) (i) on the third Business Day before the date of the proposed Borrowing, in the case of a Eurodollar Rate Borrowing or (ii) on the Business Day of the proposed Borrowing, in the case of a Reference Rate Borrowing, by the Borrower to the Administrative Agent, which shall in turn give to each Lender prompt notice of such proposed Borrowing by telecopier or telex. Each Notice of a Borrowing shall be given by telecopier or -21- telex, confirmed immediately in writing, specifying the information required therein. In the case of a proposed Borrowing comprised of Eurodollar Rate Advances, the Administrative Agent shall notify each Lender promptly of the applicable interest rate under Section 2.09(b). Each Lender shall, before noon (Dallas, Texas time) on the date of such Borrowing, make available for the account of its Applicable Lending Office to the Administrative Agent at its address referred to in Section 9.02, or such other location as the Administrative Agent may specify by notice to the Lenders, in same day funds, in the case of a Borrowing, such Lender's Pro Rata Share of such Borrowing. After the Administrative Agent's receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent shall make such funds available to the Borrower at its account with the Administrative Agent. (b) Conversions and Continuations. The Borrower may elect to Convert or continue any Borrowing under this Section 2.03 by delivering an irrevocable Notice of Conversion or Continuation to the Administrative Agent at the Administrative Agent's office no later than 10:00 a.m. (Dallas, Texas time) (i) on the date which is at least three Business Days in advance of the proposed Conversion or continuation date in the case of a Conversion to or a continuation of a Borrowing comprised of Eurodollar Rate Advances and (ii) on the Business Day of the proposed Conversion in the case of a Conversion to a Borrowing comprised of Reference Rate Advances. Each such Notice of Conversion or Continuation shall be in writing or by telex or telecopier confirmed immediately in writing specifying the information required therein. Promptly after receipt of a Notice of Conversion or Continuation under this Section, the Administrative Agent shall provide each Lender with a copy thereof and, in the case of a Conversion to or a Continuation of a Borrowing comprised of Eurodollar Rate Advances, notify each Lender of the applicable interest rate under Section 2.09(b). (c) Certain Limitations. Notwithstanding anything to the contrary in paragraphs (a) and (b) above: (i) at no time shall there be more than six Interest Periods applicable to outstanding Eurodollar Rate Advances and the Borrower may not select Eurodollar Rate Advances for any Borrowing at any time that a Default has occurred and is continuing; (ii) if any Lender shall, at least one Business Day before the date of any requested Borrowing, Conversion, or continuation, notify the Administrative 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 Lender 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 Lender shall be suspended until such Lender shall notify the Administrative Agent that the circumstances causing such suspension no longer exist, and the Advance made by such Lender in respect of such Borrowing, Conversion, or continuation shall be a Reference Rate Advance; (iii) if the Administrative 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 Administrative Agent shall notify the Borrower and the Lenders that the -22- circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be a Reference Rate Advance; (iv) if the Majority Lenders shall, at least one Business Day before the date of any requested Borrowing, notify the Administrative Agent that the Eurodollar Rate for Eurodollar Rate Advances comprising such Borrowing will not adequately reflect the cost to such Lenders 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 Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be a Reference Rate Advance; and (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 1.01 and paragraph (b) above, the Administrative Agent shall forthwith so notify the Borrower and the Lenders and such Advances shall be made available to the Borrower on the date of such Borrowing as Reference Rate Advances or, if an existing Advance, Converted into Reference 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 for which the related Notice of Borrowing specifies the Borrowing is to be comprised of Eurodollar Rate Advances, the Borrower shall indemnify each Lender against any loss, out-of-pocket cost, or expense incurred by such Lender 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 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 Lender to fund the Advance to be made by such Lender as part of such Borrowing when such Advance, as a result of such failure, is not made on such date. (e) Administrative Agent Reliance. Unless the Administrative Agent shall have received notice from a Lender before the date of any Borrowing that such Lender shall not make available to the Administrative Agent such Lender's Pro Rata Share of a Borrowing, the Administrative Agent may assume that such Lender has made its Pro Rata Share of such Borrowing available to the Administrative Agent on the date of such Borrowing in accordance with paragraph (a) of this Section 2.03 and the Administrative 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 Lender shall not have so made its Pro Rata Share of such Borrowing available to the Administrative Agent, such Lender and the Borrower severally agree to immediately repay to the Administrative 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 Administrative 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 Lender, the Federal Funds Rate for such day. If such Lender shall repay to the Administrative Agent such corresponding amount and interest as provided above, such corresponding amount so repaid shall constitute such Lender's Advance as part of such Borrowing for purposes of this -23- Agreement even though not made on the same day as the other Advances comprising such Borrowing. (f) Lender Obligations Several. The failure of any Lender to make the Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, to make its Advance on the date of such Borrowing. No Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on the date of any Borrowing. Section 2.04 Reduction of the Commitments. (a) The Borrower shall have the right, upon at least three Business Days' irrevocable notice to the Administrative Agent, to terminate in whole or reduce ratably in part the unused portion of the Commitments; provided that each partial reduction shall be in the aggregate amount of $1,000,000 or in integral multiples of $1,000,000 in excess thereof. (b) Any reduction and termination of the Commitments pursuant to this Section 2.04 shall be applied ratably to each Lender's Commitment and shall be permanent, with no obligation of the Lenders to reinstate such Commitments. Section 2.05 Prepayment of Advances. (a) Optional. The Borrower may prepay the Advances, after giving by 10:00 a.m. (Dallas, Texas time) (i) in the case of Eurodollar Rate Advances, at least three Business Days' or (ii) in the case of Reference Rate Advances, same Business Day's, irrevocable prior written notice to the Administrative Agent stating the proposed date and aggregate principal amount of such prepayment. If any such notice is given, the Borrower shall prepay the Advances in whole or ratably in part in an aggregate principal amount equal to the amount specified in such notice, together with accrued interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.12 as a result of such prepayment being made on such date; provided, however, that each partial prepayment with respect to: (A) any Eurodollar Rate Advances shall be applied to Eurodollar Rate Advances comprising part of the same Borrowing; (B) any Reference Rate Advances shall be made in minimum amounts of $500,000 and in integral multiples of $100,000 in excess thereof, and (C) any Borrowing comprised of Eurodollar Rate Advances shall be made in $1,000,000 and in integral multiples of $1,000,000 in excess thereof and in an aggregate principal amount such that after giving effect thereto such Borrowing shall have a principal amount outstanding of at least $1,000,000. Full prepayments of any Borrowing are permitted without restriction of amounts. (b) Borrowing Base Deficiency. If the aggregate outstanding amount of the Advances plus the Letter of Credit Exposure ever exceeds the lesser of the Borrowing Base and the aggregate Commitments, the Borrower shall, after receipt of written notice from the Administrative Agent regarding such deficiency, deliver to the Administrative Agent, within 10 days of receipt of such notice from the Administrative Agent, a written response indicating which of the following actions it intends to take to remedy the Borrowing Base deficiency (and the failure of the Borrower to deliver such election notice or to perform the action chosen to remedy such Borrowing Base deficiency shall constitute an Event of Default): -24- (i) prepay Advances or, if the Advances have been repaid in full, make deposits into the Cash Collateral Account to provide cash collateral for the Letter of Credit Exposure, such that the Borrowing Base deficiency is cured within 10 days after the date such deficiency notice is received by the Borrower from the Administrative Agent; (ii) pledge as Collateral for the Obligations additional Oil and Gas Properties acceptable to the Administrative Agent and each of Lenders such that the Borrowing Base deficiency is cured within 30 days after the date such deficiency notice is received by the Borrower from the Administrative Agent; or (iii) (A) deliver, within 10 days after the date such deficiency notice is received by the Borrower, to the Administrative Agent written notice indicating the Borrower's election to repay the Advances and make deposits into the Cash Collateral Account to provide cash collateral for the Letters of Credit, each in six monthly installments equal to one-sixth of such Borrowing Base deficiency with the first such installment due 30 days after the date such deficiency notice is received by the Borrower from the Administrative Agent and each following installment due 30 days after the preceding installment, and (B) make such payments and deposits within such time periods. Each prepayment pursuant to this Section 2.05(b) 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 2.12 as a result of such prepayment being made on such date. Each prepayment under clauses (i) and (iii) of this Section 2.05(b) shall be applied first to the payment of outstanding Reference Rate Advances, if any, and then to the payment of all other Advances as determined by the Administrative Agent and agreed to by the Lenders in their sole discretion. (c) Reduction of Commitments. On the date of each reduction of the aggregate Commitments pursuant to Section 2.04, the Borrower agrees to make a prepayment in respect of the outstanding amount of the Advances to the extent, if any, that the aggregate unpaid principal amount of all Advances plus the Letter of Credit Exposure exceeds the lesser of (A) the aggregate Commitments, as so reduced and (B) the Borrowing Base. Each prepayment pursuant to this Section 2.05(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 2.12 as a result of such prepayment being made on such date. (d) Illegality. If any Lender shall notify the Administrative 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 Lender or its Eurodollar Lending Office to perform its obligations under this Agreement to maintain any Eurodollar Rate Advances of such Lender 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 Lender 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 Lender 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 2.12 as a result of such prepayment being made on such date, (ii) such Lender shall simultaneously make a Reference Rate Advance -25- to the Borrower on such date in an amount equal to the aggregate principal amount of the Eurodollar Rate Advances prepaid to such Lender, and (iii) the right of the Borrower to select Eurodollar Rate Advances from such Lender for any subsequent Borrowing shall be suspended until such Lender gives notice referred to above shall notify the Administrative Agent that the circumstances causing such suspension no longer exist. (e) No Additional Right; Ratable Prepayment. The Borrower shall have no right to prepay any principal amount of any Advance except as provided in this Section 2.05, and all notices given pursuant to this Section 2.05 shall be irrevocable and binding upon the Borrower. Each payment of any Advance pursuant to this Section 2.05 shall be made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part. Section 2.06 Repayment of Advances. The Borrower shall repay to the Administrative Agent for the ratable benefit of the Lenders the outstanding principal amount of each Advance, together with any accrued interest, on the Maturity Date or such earlier date pursuant to Section 7.02 or Section 7.03. Section 2.07 Letters of Credit. (a) Commitment. From time to time from the date of this Agreement until 30 days prior to the Commitment Termination Date, at the request of the Borrower, the Issuing Lender shall, on the terms and conditions hereinafter set forth, issue, increase, or extend the Expiration Date of, Letters of Credit for the account of the Borrower on any Business Day. No Letter of Credit will be issued, increased, or extended: (i) if such issuance, increase, or extension would cause the Letter of Credit Exposure to exceed the lesser of (A) $10,000,000.00 or (B) the lesser of (I) the aggregate Commitments less the aggregate outstanding principal amount of all Advances and (II) the Borrowing Base less the aggregate outstanding principal amount of all Advances; (ii) if such Letter of Credit has an Expiration Date later than the earlier of (A) one year 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 Lender to the beneficiary of such Letter of Credit) and (B) the Commitment Termination Date; (iii) unless such Letter of Credit Documents are in form and substance acceptable to the Issuing Lender 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; (v) unless the Borrower has delivered to the Issuing Lender a completed and executed Letter of Credit Application; and (vi) unless such Letter of Credit is governed by the Uniform Customs and Practices for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500 or any successor to such publication. If the terms of any Letter of Credit -26- Application referred to in the foregoing clause (v) conflicts with the terms of this Agreement, the terms of this Agreement shall control. (b) Participations. Upon the date of the issuance or increase of a Letter of Credit, the Issuing Lender shall be deemed to have sold to each other Lender having a Commitment, and each other Lender having a Commitment shall have been deemed to have purchased from the Issuing Lender, a participation in the related Letter of Credit Obligations equal to such Lender's Pro Rata Share at such date and such sale and purchase shall otherwise be in accordance with the terms of this Agreement. The Issuing Lender shall notify each such participant Lender having a Commitment promptly by telex, telephone, or telecopy of each Letter of Credit issued, increased, or extended or converted and the actual dollar amount of such Lender's participation in such Letter of Credit. (c) Issuing. Each Letter of Credit shall be issued, increased, or extended pursuant to a Letter of Credit Application (or by telephone notice promptly confirmed in writing by a Letter of Credit Application), given not later than 10:00 a.m. (Dallas, Texas time) on the fifth Business Day before the date of the proposed issuance, increase, or extension of the Letter of Credit, and the Administrative Agent shall give to each Lender prompt notice thereof by telex, telephone, or telecopy. Each Letter of Credit Application shall be given by telecopier or telex, confirmed immediately in writing, specifying the information required therein. After the Administrative Agent's receipt of such Letter of Credit Application and upon the Borrower's fulfillment of the applicable conditions set forth in Article III, the Administrative Agent shall issue, increase, or extend such Letter of Credit for the account of the Borrower. Each Letter of Credit Application shall be irrevocable and binding on the Borrower. (d) Reimbursement. The Borrower hereby agrees to pay to the Issuing Lender on demand an amount equal to any amount paid by the Issuing Lender under any Letter of Credit. In the event the Issuing Lender makes a payment pursuant to a request for draw presented under a Letter of Credit and such payment is not reimbursed promptly by the Borrower upon demand, the Issuing Lender shall give the Administrative Agent notice of the Borrower's failure to make such reimbursement and the Administrative Agent shall notify each Lender having a Commitment promptly of the amount necessary to reimburse the Issuing Lender. Upon such notice from the Administrative Agent, each Lender having a Commitment shall reimburse the Issuing Lender promptly for such Lender's Pro Rata Share of such amount, and such reimbursement shall be deemed for all purposes of this Agreement to be an Advance to the Borrower transferred at the Borrower's request to the Issuing Lender. If such reimbursement is not made by any Lender to the Issuing Lender on the same day on which the Administrative Agent notifies such Lender to make reimbursement to the Issuing Lender hereunder, such Lender shall pay interest on its Pro Rata Share thereof to the Issuing Lender at a rate per annum equal to the Federal Funds Rate. Subject to the rights of the Borrower under Section 2.03(b), the Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Administrative Agent and the Lenders to record and otherwise treat such reimbursements to the Issuing Lender as Reference Rate Advances under a Borrowing requested by the Borrower to reimburse the Issuing Lender which have been transferred to the Issuing Lender at the Borrower's request. -27- (e) Obligations Unconditional. The obligations of the Borrower under this Agreement in respect of each Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following circumstances: (i) any lack of validity or enforceability of any Letter of Credit Document; (ii) any amendment or waiver of, or any consent to or departure from, any Letter of Credit Document; (iii) the existence of any claim, set-off, defense, or other right which the Borrower may have at any time against any beneficiary or transferee of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the Issuing Lender, or any other Person, whether in connection with this Agreement, the transactions contemplated in this Agreement or in any Letter of Credit Document, or any unrelated transaction; (iv) any statement or any other document presented under such Letter of Credit proving to be forged, fraudulent, invalid, or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; (v) payment by the Issuing Lender under such Letter of Credit against presentation of a draft or certificate which does not comply with the terms of such Letter of Credit; or (vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing; provided, however, that nothing contained in this paragraph (e) shall be deemed to constitute a waiver of any remedies of the Borrower in connection with the Letters of Credit or the Borrower's rights under Section 2.07(f) below. (f) Liability of Issuing Lender. 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 Lender 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 Lender 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 -28- (iv) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit (INCLUDING THE ISSUING LENDER'S OWN NEGLIGENCE), except that the Borrower shall have a claim against the Issuing Lender, and the Issuing Lender 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 the Issuing Lender'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. In furtherance and not in limitation of the foregoing, the Issuing Lender 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 2.05(b), 7.02(b), or 7.03(b), then the Borrower and the Issuing Lender shall establish the Cash Collateral Account and the Borrower shall execute any documents and agreements, including the Issuing Lender's standard form assignment of deposit accounts, that the Issuing Lender requests in connection therewith to establish the Cash Collateral Account and grant the Issuing Lender a first priority security interest in such account and the funds therein. The Borrower hereby pledges to the Issuing Lender and grants the Issuing Lender 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. (ii) So long as no Default or Event of Default Exists, (A) the Issuing Lender may apply the funds held in the Cash Collateral Account only to the reimbursement of any Letter of Credit Obligations, and (B) the Issuing Lender 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 Default or Event of Default, the Issuing Lender may apply any funds held in the Cash Collateral Account to the Obligations in any order determined by the Issuing Lender, regardless of any Letter of Credit Exposure which may remain outstanding; provided that, if the Issuing Lender elects to apply such funds against the Advances, the Issuing Lender shall apply the funds first to the payment of outstanding Reference Rate Advances, if any, and then to the payment of all other Advances as determined by the Issuing Lender and agreed to by the Lenders in their sole discretion. The Issuing Lender may in its sole discretion at any time release to the Borrower any funds held in the Cash Collateral Account. (iii) The Issuing Lender 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 Issuing Lender accords its own property, it being understood that the Issuing Lender shall not have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any such funds. -29- Section 2.08 Fees. (a) Commitment Fees. (i) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee at a per annum rate of .50% on the average daily amount by which (A) the lesser of (1) such Lender's Pro Rata Share of the Borrowing Base and (2) such Lender's Commitment exceeds (B) the sum of (1) such Lender's Pro Rata share of the aggregate outstanding Advances and (2) such Lender's Pro Rata Share of the Letter of Credit Exposure, from the date of this Agreement until the Commitment Termination Date. (ii) The commitment fees shall be due and payable (A) quarterly in arrears on the last day of each March, June, September, and December commencing on September 30, 2002 and continuing thereafter through and including the end of the calendar quarter preceding the Commitment Termination Date and (B) on the Commitment Termination Date.

Each such fee shall be payable annually in advance on the date of the issuance, increase or extension of the Letter of Credit, and, in the case of an increase or extension only, on the date of such increase or such extension. (ii) The Borrower also agrees to pay to the Issuing Lender such other usual and customary fees associated with any transfers, amendments, drawings, negotiations or reissuances of any Letter of Credit.

(d) Borrowing Base Increase Fees. The Borrower agrees to pay to the Administrative Agent for the account of the Lenders in connection with any increase of the Borrowing Base which would result in the Borrowing Base being greater than $62,000,000, a borrowing base increase fee on the amount of such increase. The borrowing base increase fee shall be in an amount equal to .75% multiplied by the amount of the increase and shall be due and payable on the date that the increase to the Borrowing Base becomes effective. Section 2.09 Interest. The Borrower shall pay interest on the unpaid principal amount of each Advance made by each Lender from the date of such Advance until such principal amount shall be paid in full, at the following rates per annum: (a) Reference Rate Advances. If such Advance is a Reference Rate Advance, a rate per annum equal at all times to the Adjusted Reference Rate in effect from time to time plus the -30- Applicable Margin in effect from time to time, payable monthly in arrears on the last day of each month and on the date such Reference 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 Reference Rate in effect from time to time plus the Applicable Margin plus 3.00% 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 Reference Rate in effect from time to time plus the Applicable Margin plus 3.00% per annum. (c) Additional Interest on Eurodollar Rate Advances. The Borrower shall pay to each Lender, so long as any such Lender 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 Lender, 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 (i) the Eurodollar Rate for the Interest Period for such Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Advance. Such additional interest payable to any Lender shall be determined by such Lender and notified to the Borrower through the Administrative Agent (such notice to include the calculation of such additional interest, which calculation shall be conclusive in the absence of manifest error). (d) Usury Recapture. (i) If, with respect to any Lender, the effective rate of interest contracted for under the Loan Documents, including the stated rates of interest and fees contracted for hereunder and any other amounts contracted for under the Loan Documents which are deemed to be interest, at any time exceeds the Maximum Rate, then the outstanding principal amount of the loans made by such Lender hereunder shall bear interest at a rate which would make the effective rate of interest for such Lender under the Loan 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 Lender. (ii) If, when the loans made hereunder are repaid in full, the Lost Interest has not been fully recaptured by such Lender pursuant to the preceding paragraph, then, to the extent permitted by law, for the loans made hereunder by such Lender, the interest rates charged under Section 2.09 hereunder shall be retroactively increased such that the effective rate of interest -31- under the Loan 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 Lender the amount of the Lost Interest remaining to be recaptured by such Lender. (iii) NOTWITHSTANDING THE FOREGOING OR ANY OTHER TERM IN THIS AGREEMENT OR IN ANY OTHER LOAN DOCUMENT TO THE CONTRARY, IT IS THE INTENTION OF EACH LENDER AND THE BORROWER TO CONFORM STRICTLY TO ANY APPLICABLE USURY LAWS. ACCORDINGLY, IF ANY LENDER CONTRACTS FOR, CHARGES, OR RECEIVES ANY CONSIDERATION WHICH CONSTITUTES INTEREST IN EXCESS OF THAT PAYABLE AT THE MAXIMUM RATE, THEN ANY SUCH EXCESS SHALL BE CANCELED AUTOMATICALLY AND, IF PREVIOUSLY PAID, SHALL AT SUCH LENDER'S OPTION BE APPLIED TO THE OUTSTANDING AMOUNT OF THE LOANS MADE HEREUNDER BY SUCH LENDER OR BE REFUNDED TO THE BORROWER. Section 2.10 Payments and Computations. (a) Payment Procedures. The Borrower shall make each payment under this Agreement and under the Notes in Dollars not later than 10:00 a.m. (Dallas, Texas time) on the day when due to the Administrative Agent at the location referred to in the Notes (or such other location as the Administrative Agent shall designate in writing to the Borrower) in same day funds without deduction, setoff, or counterclaim of any kind. The Administrative Agent shall thereafter cause to be distributed promptly like funds relating to the payment of principal, interest or fees ratably (other than amounts payable solely to the Administrative Agent, the Issuing Lender, or a specific Lender pursuant to Section 2.08(c), 2.09(c), 2.12, 2.13, 2.14, 8.05, or 9.07, but after taking into account payments effected pursuant to Section 9.04), in accordance with each Lender's Pro Rata Share, to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender or the Issuing Lender to such Lender 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 Reference Rate and of fees shall be made by the Administrative 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 shall be made by the Administrative 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 Administrative Agent of an interest rate or fee shall be conclusive and binding for all purposes, absent manifest error. (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 -32- 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) Administrative Agent Reliance. Unless the Administrative Agent shall have received written notice from the Borrower prior to the date on which any payment is due to the Lenders that the Borrower shall not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such date an amount equal to the amount then due such Lender. If and to the extent the Borrower shall not have so made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender, together with interest, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate for such day. Section 2.11 Sharing of Payments, Etc. If any Lender 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 Lenders, such Lender shall notify the Administrative Agent and forthwith purchase from the other Lenders such participations in the Advances made by them or Letter of Credit Obligations held by them as shall be necessary to cause such purchasing Lender 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 Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such Lender's ratable share (according to the proportion of (a) the amount of the participation sold by such Lender to the purchasing Lender 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 Lender's ratable share (according to the proportion of (i) the amount of such Lender's required repayment to the purchasing Lender to (ii) the total amount of all such required repayments to the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.11 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 Lender were the direct creditor of the Borrower in the amount of such participation. Section 2.12 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 2.05, 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 Lender to the Borrower through the Administrative Agent, pay to the Administrative Agent for the account of such Lender any amounts required to compensate such Lender for any additional losses, out-of-pocket costs or expenses which it may reasonably incur as a result of such payment or nonpayment, including any loss (including loss of anticipated profits), cost or expense incurred -33- by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance. Section 2.13 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 Lender of agreeing to make or making, funding, or maintaining Eurodollar Rate Advances, then the Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to the Administrative Agent), immediately pay to the Administrative Agent for the account of such Lender additional amounts sufficient to compensate such Lender 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 Administrative Agent by such Lender shall be conclusive and binding for all purposes, absent manifest error. Each Lender will notify the Administrative Agent and the Borrower of any event occurring after the date of this Agreement which will entitle such Lender to compensation pursuant to this Section 2.13(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 Advances 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 (i) such Lender shall have no obligation to so designate an Applicable Lending Office located in the United States, and (ii) the failure to provide such notice or certificate shall not release or diminish or otherwise affect in any way the Borrower's obligation to pay such increased costs. (b) Capital Adequacy. If any Lender or the Issuing Lender 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 Lender or the Issuing Lender or any corporation controlling such Lender or the Issuing Lender and that the amount of such capital is increased by or based upon the existence of such Lender's commitment to lend or the Issuing Lender's commitment to issue the Letters of Credit and other commitments of this type, then, upon 30 days' prior written notice by such Lender or the Issuing Lender (with a copy of any such demand to the Administrative Agent), the Borrower shall immediately pay to the Administrative Agent for the account of such Lender or to the Issuing Lender, as the case may be, from time to time as specified by such Lender or the Issuing Lender, additional amounts sufficient to compensate such Lender or the Issuing Lender, in light of such circumstances, (i) with respect to such Lender, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of such Lender's commitment to lend under this Agreement and (ii) with respect to the Issuing Lender, to the extent that the Issuing Lender reasonably determines such increase in capital to be allocable to the issuance or maintenance of the Letters of Credit. A certificate as to such amounts and detailing the calculation of such amounts submitted to the Borrower by such Lender or the Issuing Lender shall be conclusive and binding for all purposes, absent manifest error. Each Lender or the Issuing Lender (as the case -34- may be) will notify the Borrower that it is entitled to compensation pursuant to this Section 2.13(b) as promptly as practicable after it determines to request such compensation; provided that the failure to provide such notice or certificate shall not release or diminish or otherwise affect in any way the Borrower's obligation to pay such additional amounts. (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 Lender or (ii) impose on the Issuing Lender 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 Lender of issuing or maintaining any Letter of Credit (which increase in cost shall be determined by the Issuing Lender's reasonable allocation of the aggregate of such cost increases resulting from such event), then, upon demand by the Issuing Lender, the Borrower shall pay to the Issuing Lender, from time to time as specified by the Issuing Lender, additional amounts which shall be sufficient to compensate the Issuing Lender for such increased cost. A certificate as to such increased cost incurred by the Issuing Lender, 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 Lender to the Borrower, shall be conclusive and binding for all purposes, absent manifest error. Section 2.14 Taxes. (a) No Deduction for Certain Taxes. Any and all payments by the Borrower shall be made, in accordance with Section 2.10, 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 Lender, and the Administrative Agent, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction under the laws of which such Lender, the Issuing Lender, or the Administrative Agent (as the case may be) is organized or any political subdivision of such 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 Lender and the Issuing Lender, Taxes by the jurisdiction of such Lender'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 Lender, the Issuing Lender, or the Administrative 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 2.14), such Lender, the Issuing Lender, or the Administrative 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 Lender's, the Issuing Lender's, or the Administrative Agent's failure to provide the forms described in paragraph (d) of this Section 2.14 and such Lender, the Issuing Lender, or the Administrative 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. -35- (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 Loan Documents (hereinafter referred to as "Other Taxes"). (c) Indemnification. THE BORROWER INDEMNIFIES EACH LENDER, THE ISSUING LENDER, AND THE ADMINISTRATIVE AGENT FOR THE FULL AMOUNT OF TAXES OR OTHER TAXES (INCLUDING ANY TAXES OR OTHER TAXES IMPOSED BY ANY JURISDICTION ON AMOUNTS PAYABLE UNDER THIS SECTION 2.14) PAID BY SUCH LENDER, THE ISSUING LENDER, OR THE ADMINISTRATIVE 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 ADMINISTRATIVE AGENT FOR THE BENEFIT OF ANY PARTY CLAIMING SUCH INDEMNIFICATION WITHIN 30 DAYS FROM THE DATE THE BORROWER RECEIVES WRITTEN DEMAND THEREFOR FROM THE ADMINISTRATIVE AGENT ON BEHALF OF ITSELF AS ADMINISTRATIVE AGENT, THE ISSUING LENDER, OR ANY SUCH LENDER. IF ANY LENDER, THE ADMINISTRATIVE AGENT, OR THE ISSUING LENDER RECEIVES A REFUND IN RESPECT OF ANY TAXES PAID BY THE BORROWER UNDER THIS PARAGRAPH (C), SUCH LENDER, THE ADMINISTRATIVE AGENT, OR THE ISSUING LENDER, AS THE CASE MAY BE, SHALL PROMPTLY PAY TO THE BORROWER THE BORROWER'S SHARE OF SUCH REFUND. (d) Foreign Lender Withholding Exemption. Each Lender and Issuing Lender that is not incorporated under the laws of the United States of America or a state thereof agrees that it shall deliver to the Borrower and the Administrative Agent (i) two duly completed copies of United States Internal Revenue Service Form 1001 or 4224 or successor applicable form, as the case may be, certifying in each case that such Lender is entitled to receive payments under this Agreement and the Notes payable to it, without deduction or withholding of any United States federal income taxes, (ii) if applicable, an Internal Revenue Service Form W-8 or W-9 or successor applicable form, as the case may be, to establish an exemption from United States backup withholding tax, and (iii) any other governmental forms which are necessary or required under an applicable tax treaty or otherwise by law to reduce or eliminate any withholding tax, which have been reasonably requested by the Borrower. Each Lender which delivers to the Borrower and the Administrative Agent a Form 1001 or 4224 and Form W-8 or W-9 pursuant to the next preceding sentence further undertakes to deliver to the Borrower and the Administrative Agent two further copies of the said letter and Form 1001 or 4224 and Form W-8 or W-9, or successor applicable forms, or other manner of certification, as the case may be, on or before the date that any such letter or form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent letter and form previously delivered by it to the Borrower and the Administrative Agent, and such extensions or renewals thereof as may reasonably be requested by the Borrower and the Administrative Agent certifying in the case of a Form 1001 or 4224 that such Lender is entitled to receive payments under this Agreement without deduction or -36- withholding of any United States federal income taxes. If an event (including 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 Lender from duly completing and delivering any such letter or form with respect to it and such Lender advises the Borrower and the Administrative 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-8 or W-9, establishing an exemption from United States backup withholding tax, such Lender shall not be required to deliver such letter or forms. The Borrower shall withhold tax at the rate and in the manner required by the laws of the United States with respect to payments made to a Lender failing to timely provide the requisite Internal Revenue Service forms. Section 2.15 Replacement Lenders (a) If any Lender has notified the Borrower and the Administrative Agent of its incurring the increased costs as described under Section 2.13(a) or has required the Borrower to make payments for Taxes under Section 2.14, then the Borrower may, unless such Lender has notified the Borrower and the Administrative Agent that the circumstances giving rise to such notice no longer apply, terminate, in whole but not in part, the Commitment of such Lender (other than the Administrative Agent) (the "Terminated Lender") at any time upon five (5) Business Days' prior written notice to the Terminated Lender and the Administrative 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 Administrative Agent and become parties by executing an Assignment and Acceptance (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 and Acceptance 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 Advances (if any) then outstanding and participation -37- 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 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 9.06(a), and the Terminated Lender will have the rights and benefits of an assignor under Section 9.06(a). To the extent not in conflict, the terms of Section 9.06(a) shall supplement the provisions of this Section 2.15. For each assignment made under this Section 2.15, the Replacement Lender shall pay to the Administrative Agent the processing fee provided for in Section 9.06(a). The Borrower will be responsible for the payment of any breakage costs associated with termination and Replacement Lenders, as set forth in Section 2.12.

Additionally, there is no pending or, to the best knowledge of the Borrower, threatened action or proceeding instituted against the Borrower or any of its Subsidiaries which seeks to adjudicate the Borrower or any such Subsidiary as bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment, protection, relief, or composition of it or its debts under any law relating to bankruptcy, insolvency or reorganization or relief of debtors, or seeking the entry of an order for relief or the appointment of a receiver, trustee or other similar official for it or for any substantial part of its Property.

Neither the -43- Administrative Agent nor any of the Lenders, solely by virtue of the execution, delivery and performance of, and the consummation of the transactions contemplated by, the Loan Documents shall be or become subject to regulation (a) as a "holding company", or an "affiliate" of a "holding company," within the meaning of the Public Utility Holding Company Act of 1935, as amended, (b) under the Federal Power Act, as amended, (c) as a "public utility" or "public service corporation" or the equivalent under the applicable law of any state, or (d) under the applicable laws of any state relating to public utilities or public service corporations. Section 4.11 Taxes. (a) Reports and Payments. All Returns (as defined below in clause (c) of this Section) required to be filed by or on behalf of the Borrower, its Subsidiaries (other than Foreign 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 and such Returns are and will be true, complete and correct, except where the failure to so file would not be reasonably expected to cause a Material Adverse Change; and all Taxes shown to be payable on the Returns or on subsequent assessments with respect thereto will have been paid in full on a timely basis, and no other Taxes will be payable by the Tax Group with respect to items or periods covered by such Returns, except in each case to the extent of (i) reserves reflected in the Financial Statements and the Interim Financial Statements, (ii) taxes that are being contested in good faith, or (iii) such Taxes, the failure to pay which would not cause a Material Adverse Change. The reserves for accrued Taxes reflected in the financial statements delivered to the Lenders 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. (b) Taxes Definition. "Taxes" in this Section 4.11 shall mean all taxes, charges, fees, levies, or other assessments imposed by any federal, state, local, or foreign taxing authority, including income, gross receipts, excise, real or personal property, sales, occupation, use, service, leasing, environmental, value added, transfer, payroll, and franchise taxes (and including any interest, penalties, or additions to tax attributable to or imposed on with respect to any such assessment). (c) Returns Definition. "Returns" in this Section 4.11 shall mean any federal, state, local, or foreign report, estimate, declaration of estimated Tax, information statement or return relating to, or required to be filed in connection with, any Taxes, including any information return or report with respect to backup withholding or other payments of third parties. 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 in accordance 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 -44- 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 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(1) 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 its Subsidiaries (other than Foreign Subsidiaries) 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 (other than Foreign Subsidiaries) are in good repair, working order and condition. Since the date of the Interim Financial Statements, neither the business nor the material Properties of the Borrower and each of its Subsidiaries (other than Foreign 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. (a) 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 would reasonably be expected to cause a Material Adverse Change. Except as may be determined in any litigation set forth in Schedule 4.07, neither the Borrower nor any of its Subsidiaries (other than Foreign Subsidiaries) is in default under or with respect to any contract, agreement, lease, or other instrument to which the Borrower or any such Subsidiary is a party and which could reasonably be expected to cause a Material Adverse Change. Except as may be determined in any litigation set forth in Schedule 4.07, neither the Borrower nor any Subsidiary (other than Foreign Subsidiaries) has received any notice of default under any material contract, agreement, lease, or other instrument to which the Borrower or such Subsidiary is a party.

Except as set forth on Schedule 4.15, 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 Subsidiaries (other than Foreign Subsidiaries) or any of their 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 (other than Foreign 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.
