Nothing in this Section 2.1(c) shall be deemed to limit any Bank's obligation to reimburse Administrative Agent with respect to its participation in Letters of Credit as a result of the drawing under any Letter of Credit pursuant to Section 2.1(c). (d) proceeds of Borrowings hereunder and Letters of Credit issued hereunder shall be used only (a) to pay up to $14,500,000 of the purchase price for the Apache Acquisition (including related transaction costs), (b) to pay Approved Cap Ex in an amount up to $4,800,000, and (c) for other general corporate purposes; provided, that no Borrowing shall be made for such other general corporate purposes in an amount greater than the Unrestricted Advance Limit in effect immediately prior to giving effect to such Borrowing unless and to the extent that such Borrowing is made from Incremental Availability. Letters of Credit may be used for general corporate purposes. Notwithstanding the foregoing, Borrowing shall be made or Letter of Credit issued for any purpose prohibited by Section 10.7 hereof. (e) In order to request any Borrowing under this Section 2.1, Borrower shall hand deliver, telex or telecopy to Administrative Agent a duly completed Request for Borrowing (herein so called) prior to 12:00 noon (Dallas, Texas time), (i) at least one (1) Domestic Business Day before the Borrowing Date specified for a proposed Base Rate Borrowing, and (ii) at least three (3) Eurodollar Business Days before the Borrowing Date of a proposed Eurodollar Borrowing. Each such Request for Borrowing shall be substantially in the form of Exhibit F hereto, and shall specify: (i) the Borrowing Date of such Borrowing, which shall be a Domestic Business Day in the case of a Base Rate Borrowing or a Eurodollar Business Day in the case of a Eurodollar Borrowing; (ii) the aggregate amount of such Borrowing; (iii) whether such Borrowing is to be a Base Rate Borrowing or a Eurodollar Borrowing; (iv) in the case of a Eurodollar Borrowing, the duration of the Interest Period applicable thereto, subject to the provisions of the definition of Interest Period; and 23 30 (v) The use of proceeds of such Borrowing. Upon receipt of a Request for Borrowing, Administrative Agent shall promptly notify each Bank of the contents thereof and the amount of the Borrowing to be loaned by such Bank pursuant thereto, and such Request for Borrowing shall not thereafter be revocable by Borrower. Not later than 12:00 noon (Dallas, Texas time) on the date of each Borrowing, each Bank shall make available its Commitment Percentage of such Borrowing, in Federal or other funds immediately available in Dallas, Texas to Administrative Agent at its address set forth on Schedule 1 hereto. Notwithstanding the foregoing, if Borrower delivers to Administrative Agent a Request for Borrowing prior to 10:00 a.m. (Dallas, Texas time) on a Domestic Business Day requesting a Base Rate Borrowing on such day, each Bank shall use its best efforts to make available to Administrative Agent its Commitment Percentage of such Borrowing by 1:00 p.m. (Dallas, Texas time) on the same day. Unless Administrative Agent determines that any applicable condition specified in Section 7.2 has not been satisfied, Administrative Agent will make the funds so received from Banks available to Borrower at Administrative Agent's aforesaid address. (f) In order to request any Letter of Credit hereunder, Borrower shall hand deliver, telex or telecopy to Administrative Agent a duly completed Request for Letter of Credit (herein so called) prior to 12:00 noon (Dallas, Texas time) at least three (3) Domestic Business Days before the date specified for issuance of such Letter of Credit. Each Request for Letter of Credit shall be substantially in the form of Exhibit G hereto, shall be accompanied by Administrative Agent's duly completed and executed letter of credit application and agreement and shall specify: (i) the requested date for issuance of such Letter of Credit; (ii) the terms of such requested Letter of Credit, including the name and address of the beneficiary, the stated amount, the expiration date and the conditions under which drafts under such Letter of Credit are to be available; and (iii) the purpose of such Letter of Credit. Upon receipt of a Request for Letter of Credit, Administrative Agent shall promptly notify each Bank of the contents thereof, including the amount of the requested Letter of Credit, and such Request for Letter of Credit shall not thereafter be revocable by Borrower. No later than 12:00 noon (Dallas, Texas time) on the date each Letter of Credit is requested, unless Administrative Agent determines that any applicable condition precedent set forth in Section 7.2 hereof has not been satisfied, Administrative Agent will issue and deliver such Letter of Credit pursuant to the instructions of Borrower. SECTION 2.2 Notes. Each Bank's Commitment Percentage of the Revolving Loan shall be evidenced by a single Note payable to the order of such Bank in an amount equal to such Bank's Commitment. 24 31 SECTION 2.3 Interest Rates; Payments. (a) The principal amount of the Base Rate Loan outstanding from day to day shall bear interest at a rate per annum equal to the Base Rate in effect from day to day; provided that in no event shall the rate charged hereunder or under the Notes exceed the Maximum Lawful Rate. Interest on the principal of the Base Rate Loan shall be payable as it accrues pursuant to Section 2.5 and on each Quarterly Date, and on the Termination Date. (b) The principal amount of each Eurodollar Loan shall bear interest for the Interest Period applicable thereto at a rate per annum equal to the sum of (i) the Applicable Margin, plus (ii) the applicable Adjusted Eurodollar Rate; provided that in no event shall the rate charged hereunder or under the Notes exceed the Maximum Lawful Rate. Interest on any portion of the principal of each Eurodollar Loan shall be payable as it accrues pursuant to Section 2.5 and, in the case of accrued interest which is not fully paid pursuant to Section 2.5 and which (i) accrues on the outstanding principal balance of a Eurodollar Loan subject to an Interest Period of one (1), two (2) or three (3) months shall be payable on the last day of the Interest Period applicable thereto, and (ii) on the outstanding principal balance of any Loan having an Interest Period of more than three (3) months shall be payable on the last day of the Interest Period applicable thereto and on each Quarterly Date. (c) So long as no Default or Event of Default shall be continuing, subject to the provisions of this Section 2.3, Borrower shall have the option of having all or any portion of the principal outstanding under the Revolving Loan be a Base Rate Loan or one (1) or more Eurodollar Loans, which shall bear interest at rates determined by reference to the Base Rate and the Adjusted Eurodollar Rate, respectively; provided, that each Eurodollar Loan shall be in a minimum amount of $500,000 and shall be in an amount which is an integral multiple of $100,000. Prior to the termination of each Interest Period with respect to each Eurodollar Loan, Borrower shall give written notice (a "Notice of Continuation or Conversion") in the form of Exhibit H attached hereto to Administrative Agent of the Type of Loan which shall be applicable to the principal of such Eurodollar Loan upon the expiration of such Interest Period. Such Notice of Continuation or Conversion shall be given to Administrative Agent at least one (1) Domestic Business Day, in the case of a Base Rate Loan selection and three (3) Eurodollar Business Days, in the case of a Eurodollar Loan selection, prior to the termination of the Interest Period then expiring. If Borrower shall specify a Eurodollar Loan, such Notice of Continuation or Conversion shall also specify the length of the succeeding Interest Period (subject to the definition of such term) selected by Borrower. Each Notice of Continuation or Conversion shall be irrevocable and effective upon notification thereof to Administrative Agent. If the required Notice of Continuation or Conversion shall not have been timely received by Administrative Agent, Borrower shall be deemed to have elected that the principal of the Eurodollar Loan subject to the Interest Period then expiring be a part of the Base Rate Loan upon the expiration of such Interest Period and Borrower will be deemed to have given Administrative Agent notice of such election. Subject to the limitations set forth in this Section 2.3(c) on the amount and number of Eurodollar Loans, Borrower shall have the right to convert (a "Conversion") all or any part of the Base Rate Loan to a Eurodollar Loan by giving Administrative 25 32 Agent a Notice of Continuation or Conversion of such election at least three (3) Eurodollar Business Days prior to the date on which Borrower elects to make such conversion (a "Conversion Date"). The Conversion Date selected by Borrower shall be a Eurodollar Business Day. Notwithstanding anything in this Section 2.3 to the contrary, no portion of the principal of the Base Rate Loan may be Converted to a Eurodollar Loan and no Eurodollar Loan may be Continued as such when any Default or Event of Default has occurred and is continuing, but each such Eurodollar Loan shall be automatically Converted to the Base Rate Loan on the last day of each applicable Interest Period. Borrower shall not be permitted to have more than four (4) Eurodollar Loans in effect at any time. (d) Notwithstanding anything to the contrary set forth in Section 2.3(a) or 2.3(b) above, all overdue principal of the Obligations and, to the extent permitted by law, overdue interest, shall bear interest from the date due, payable on demand, for each day until paid at a rate per annum equal to the lesser of (a) the sum of (i) two percent (2%), plus (ii) the Base Rate in effect from day to day, and (b) the Maximum Lawful Rate. (e) Administrative Agent shall determine each interest rate applicable to the Revolving Loan in accordance with the terms hereof. Administrative Agent shall promptly notify Borrower and Banks by telex, telecopy or cable of each rate of interest so determined, and its determination thereof shall be conclusive in the absence of manifest error. (f) Notwithstanding the foregoing, if at any time the rate of interest calculated with reference to the Base Rate or the Eurodollar Rate hereunder (the "contract rate") is limited to the Maximum Lawful Rate, any subsequent reductions in the contract rate shall not, to the extent permitted by law, reduce the rate of interest on the affected Loan below the Maximum Lawful Rate until the total amount of interest accrued equals the amount of interest which would have accrued if the contract rate had at all times been in effect. In the event that at maturity (stated or by acceleration), or at final payment of any Note, the total amount of interest paid or accrued on such Note is less than the amount of interest which would have accrued if the contract rate had at all times been in effect with respect thereto, then at such time, to the extent permitted by law, Borrower shall pay to the holder of such Note an amount equal to the difference between (i) the lesser of the amount of interest which would have accrued if the contract rate had at all times been in effect and the amount of interest which would have accrued if the Maximum Lawful Rate had at all times been in effect, and (ii) the amount of interest actually paid on such Note. (g) Interest payable hereunder computed by reference to the Eurodollar Rate shall be computed based on the number of actual days elapsed assuming that each calendar year consisted of 360 days. Interest payable hereunder computed by reference to the Base Rate shall be computed based on the actual number of days elapsed assuming that each calendar year consisted of 365 days. SECTION 2.4 Mandatory Prepayments During Borrowing Base Deficiency. In the event a Borrowing Base Deficiency exists after giving effect to any Redetermination, Borrower shall take the action specified in either clause (a), (b) or (c) following, as specified by Administrative Agent in its sole discretion in a written notice to Borrower: (a) eliminate such Borrowing Base Deficiency by 26 33 making a single mandatory prepayment of principal on the Revolving Loan in an amount equal to the entire amount of such Borrowing Base Deficiency on the first Monthly Date following the date on which such Borrowing Base Deficiency is determined to exist, (b) eliminate such Borrowing Base Deficiency by making six (6) consecutive mandatory prepayments of principal on the Revolving Loan each of which shall be in the amount of one sixth (1/6th) of the amount of such Borrowing Base Deficiency commencing on the first Monthly Date following the date on which such Borrowing Base Deficiency is determined to exist and continuing on each Monthly Date thereafter, or (c) eliminate such Borrowing Base Deficiency by submitting additional Mineral Interests to Banks on the first Monthly Date following the date on which such Borrowing Base Deficiency is determined to exist for evaluation as Borrowing Base Properties which Banks, in their sole discretion, determine have a value sufficient to increase the Borrowing Base by at least the amount of the Borrowing Base Deficiency. If a Borrowing Base Deficiency cannot be eliminated pursuant to this Section 2.4 by prepayment of the Revolving Loan in full (as a result of outstanding Letter of Credit Exposure), on each Monthly Date, Borrower shall also deposit cash with Administrative Agent, to be held by Administrative Agent to secure outstanding Letter of Credit Exposure in the manner contemplated by Section 2.1(b), in an amount at least equal to one sixth (1/6th) of the balance of such Borrowing Base Deficiency (i.e., one-sixth of the difference between the Borrowing Base Deficiency and the remaining outstanding principal of the Revolving Loan on the date such Borrowing Base Deficiency is first determined to occur). SECTION 2.5 Mandatory Prepayments from Cash Flow. Commencing on September 25, 1999 and continuing on the 20th day of each month thereafter until the Commitments are terminated and the Obligations are paid in full, Borrower shall make a mandatory prepayment on the Revolving Loan in an amount equal to fifty percent (50%) of Borrower's Net Revenues for the immediately preceding calendar month. Each such payment shall be applied first to accrued but unpaid interest and then to principal. In the event mandatory prepayments are required under this Section 2.5 at any time when mandatory prepayments are required under Section 2.4, the mandatory prepayments required by this Section 2.5 shall be applied to reduce the prepayments Borrower is required to make pursuant to Section 2.4 in direct order of maturity. SECTION 2.6 Voluntary Reduction of Commitments. Borrower may, by notice to Administrative Agent five (5) Domestic Business Days prior to the effective date of any such reduction, reduce the Total Commitment (and thereby reduce the Commitment of each Bank ratably) in amounts not less than $5,000,000 and in an amount which is an integral multiple of $1,000,000. On the effective date of any such reduction, Borrower shall, to the extent required as a result of such reduction, make a principal payment on the Revolving Loan in an amount sufficient to cause the principal balance of the Revolving Loan to be equal to or less than the Total Commitment as thereby reduced. Notwithstanding the foregoing, Borrower shall not be permitted to voluntarily reduce the Total Commitment to an amount less than the aggregate Letter of Credit Exposure of all Banks. SECTION 2.7 Termination of Commitments; Final Maturity of Revolving Loan. The Total Commitment (and the Commitment of each Bank) shall terminate, and the entire outstanding principal 27 34 balance of the Revolving Loan, all interest accrued thereon, all accrued but unpaid fees hereunder and all other outstanding Obligations shall be due and payable in full on the Termination Date. SECTION 2.8 Unused Commitment Fee. On the Termination Date, on each Quarterly Date prior to the Termination Date, and, in the event the Commitments are terminated in their entirety prior to the Termination Date, on the date of such termination, Borrower shall pay to Administrative Agent, for the ratable benefit of each Bank, a commitment fee equal to .375% (computed on a per annum basis on the basis of actual days elapsed and as if each calendar year consisted of 365 days) of the average daily Availability for the Fiscal Quarter (or portion thereof) ending on the date such payment is due. SECTION 2.9 Borrowing Base Increase Fee. Simultaneously with each increase in the Borrowing Base, Borrower shall pay to Administrative Agent for the ratable benefit of each Bank, a borrowing base increase fee in an amount to be mutually agreed upon by Borrower and Administrative Agent in connection with such increase. SECTION 2.10 Letter of Credit Fee. (a) Borrower shall pay to Administrative Agent for its own account a fee on the daily average amount of all Letter of Credit Exposure computed at a per annum rate for each day of .125% of such daily average Letter of Credit Exposure. Such fee shall be payable in arrears on each Quarterly Date. Notwithstanding the foregoing, no fee shall accrue or be payable pursuant to this Section 2.10(a) at any time that there is only one Bank which is a party to this Credit Agreement. (b) Borrower shall pay to Administrative Agent for the ratable benefit of each Bank a fee on the daily average amount of all Letter of Credit Exposure computed at a per annum rate for each day equal to the Applicable Margin in effect for Eurodollar Loans on such day. Such fee shall be payable quarterly in arrears on each Quarterly Date. SECTION 2.11 Agency and other Fees. Borrower shall pay to Administrative Agent and its Affiliates such other reasonable fees and amounts as Borrower shall be required to pay to Administrative Agent and its Affiliates from time to time pursuant to any separate agreement between Borrower and Administrative Agent or such Affiliates. Such fees and other amounts shall be retained by Administrative Agent and its Affiliates, and no Bank (other than Administrative Agent) shall have any interest therein. SECTION 2.12 Closing Fee. Borrower shall pay to Administrative Agent, for the ratable benefit of each Bank, a non-refundable closing fee on the Closing Date in the amount of $48,750. 28 35 ARTICLE 3 GENERAL PROVISIONS SECTION 3.1 Delivery and Endorsement of Notes. Simultaneously with the execution of this Agreement, Administrative Agent shall deliver to each Bank the Note payable to such Bank. Each Bank may endorse (and prior to any transfer of its Note shall endorse) on the schedules attached and forming a part thereof appropriate notations to evidence the date and amount of its Commitment Percentage of each Borrowing and type of each Loan made by it, the Interest Period applicable thereto, and the date and amount of each payment of principal made by Borrower with respect thereto; provided that the failure by any Bank to so endorse its Note shall not affect the liability of Borrower for the repayment of all amounts outstanding under such Note together with interest thereon. Each Bank is hereby irrevocably authorized by Borrower to endorse its Note and to attach to and make a part of any Note a continuation of any such schedule as required. SECTION 3.2 General Provisions as to Payments. (a) Borrower shall make each payment of principal of, and interest on, the Revolving Loan and all fees payable hereunder shall be paid not later than 12:00 noon (Dallas, Texas time) on the date when due, in Federal or other funds immediately available in Dallas, Texas, to Administrative Agent at its address set forth on Schedule 1 hereto. Administrative Agent will promptly (and if such payment is received by Administrative Agent by 10:00 a.m. (Dallas, Texas time) and otherwise if reasonably possible, on the same Domestic Business Day) distribute to each Bank its Commitment Percentage of each such payment received by Administrative Agent for the account of Banks. Whenever any payment of (a) principal of, or interest on, any portion of the Base Rate Loan, or (b) fees shall be due on a day which is not a Domestic Business Day, the date for payment thereof shall be extended to the next succeeding Domestic Business Day. Whenever any payment of principal of, or interest on, any Eurodollar Loan shall be due on a day which is not a Eurodollar Business Day, the date for payment thereof shall be extended to the next succeeding Eurodollar Business Day (subject to the definition of Interest Period). If the date for any payment of principal is extended by operation of Law or otherwise, interest thereon shall be payable for such extended time. Borrower hereby authorizes Administrative Agent to charge from time to time against Borrower's accounts with Administrative Agent any amount then due. (b) Prior to the occurrence of an Event of Default, all principal payments received by Banks shall be applied first to Eurodollar Loans outstanding with Interest Periods ending on the date of such payment, then to the Base Rate Loan, and then to Eurodollar Loans, next maturing until such principal payment is fully applied. (c) After the occurrence of an Event of Default, all amounts collected or received by Administrative Agent or any Bank shall be applied first to the payment of all proper costs incurred by Administrative Agent in connection with the collection thereof (including reasonable expenses and disbursements of Administrative Agent), second to the payment of all proper costs incurred by Banks 29 36 in connection with the collection thereof (including reasonable expenses and disbursements of Banks), third to the reimbursement of any advances made by Banks to effect performance of any unperformed covenants of Borrower or any of its Subsidiaries under any of the Loan Papers, fourth to the payment of any unpaid fees required pursuant to Section 2.11, fifth to the payment of any unpaid fees required pursuant to Sections 2.8, 2.9, and 2.10, sixth, to payment to each Bank of its Commitment Percentage of the outstanding principal of the Revolving Loan and accrued but unpaid interest thereon, and seventh to establish the deposits required in Section 2.1(b). All payments received by a Bank after the occurrence of an Event of Default for application to the principal of the Revolving Loan shall be applied by such Bank in the manner provided in Section 3.2(b). ARTICLE 4 CHANGE IN CIRCUMSTANCES SECTION 4.1 Increased Cost and Reduced Return. (a) If, after the date hereof, the adoption of any applicable Law, rule, or regulation, or any change in any applicable Law, rule, or regulation, or any change in the interpretation or administration thereof by any Governmental Authority, central bank, or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Applicable Lending Office) with any request or directive (whether or not having the force of Law) of any such Governmental Authority, central bank, or comparable agency: (i) shall subject such Bank (or its Applicable Lending Office) to any Tax, duty, or other charge with respect to any Eurodollar Loans, its Note, or its obligation to make Eurodollar Loans, or change the basis of taxation of any amounts payable to such Bank (or its Applicable Lending Office) under this Agreement or its Note in respect of any Eurodollar Loans (other than Taxes imposed on the overall net income of such Bank by the jurisdiction in which such Bank has its principal office or such Applicable Lending Office); (ii) shall impose, modify, or deem applicable any reserve, special deposit, assessment, or similar requirement (other than the Reserve Requirement utilized in the determination of the Adjusted Eurodollar Rate) relating to any extensions of credit or other assets of, or any deposits with or other liabilities or commitments of, such Bank (or its Applicable Lending Office), including the Commitment of such Bank hereunder; or (iii) shall impose on such Bank (or its Applicable Lending Office) or on the London interbank market any other condition affecting this Agreement or its Note or any of such extensions of credit or liabilities or commitments; 30 37 and the result of any of the foregoing is to increase the cost to such Bank (or its Applicable Lending Office) of making, Converting into, Continuing, or maintaining any Eurodollar Loans or to reduce any sum received or receivable by such Bank (or its Applicable Lending Office) under this Agreement or its Note with respect to any Eurodollar Loans, then Borrower shall pay to such Bank on demand such amount or amounts as will compensate such Bank for such increased cost or reduction. If any Bank requests compensation by Borrower under this Section 4.1(a), Borrower may, by notice to such Bank (with a copy to Administrative Agent), suspend the obligation of such Bank to make or Continue Eurodollar Loans, or to Convert all or part of the Base Rate Loan owing to such Bank to Eurodollar Loans, until the event or condition giving rise to such request ceases to be in effect (in which case the provisions of Section 4.4 shall be applicable); provided that such suspension shall not affect the right of such Bank to receive the compensation so requested. (b) If, after the date hereof, any Bank shall have determined that the adoption of any applicable Law, rule, or regulation regarding capital adequacy or any change therein or in the interpretation or administration thereof by any Governmental Authority, central bank, or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of Law) of any such Governmental Authority, central bank, or comparable agency, has or would have the effect of reducing the rate of return on the capital of such Bank or any corporation controlling such Bank as a consequence of such Bank's obligations hereunder to a level below that which such Bank or such corporation could have achieved but for such adoption, change, request, or directive (taking into consideration its policies with respect to capital adequacy), then from time to time upon demand Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank for such reduction. (c) Each Bank shall promptly notify Borrower and Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Bank to compensation pursuant to this Section 4.1 and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Bank, be otherwise disadvantageous to it. Any Bank claiming compensation under this Section 4.1 shall furnish to Borrower and Administrative Agent a statement setting forth the additional amount or amounts to be paid to it hereunder which shall be conclusive in the absence of manifest error. In determining such amount, such Bank may use any reasonable averaging and attribution methods. SECTION 4.2 Limitation on Types of Loans. If on or prior to the first day of any Interest Period for any Eurodollar Loan: (a) Administrative Agent determines (which determination shall be conclusive) that by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period; or 31 38 (b) Required Banks determine (which determination shall be conclusive) and notify Administrative Agent that the Adjusted Eurodollar Rate will not adequately and fairly reflect the cost to Banks of funding Eurodollar Loans for such Interest Period; then Administrative Agent shall give Borrower prompt notice thereof specifying the relevant amounts or periods, and so long as such condition remains in effect, Banks shall be under no obligation to make additional Eurodollar Loans, Continue Eurodollar Loans, or to Convert all or any part of the Base Rate Loan into Eurodollar Loans and Borrower shall, on the last day(s) of the then current Interest Period(s) for the outstanding Eurodollar Loans, either prepay such Eurodollar Loans or Convert such Eurodollar Loans into the Base Rate Loan in accordance with the terms of this Agreement. SECTION 4.3 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Bank or its Applicable Lending Office to make, maintain, or fund Eurodollar Loans hereunder, then such Bank shall promptly notify Borrower thereof and such Bank's obligation to make or Continue Eurodollar Loans and to Convert all or any part of the Base Rate Loan into Eurodollar Loans shall be suspended until such time as such Bank may again make, maintain, and fund Eurodollar Loans (in which case the provisions of Section 2.7 shall be applicable). SECTION 4.4 Treatment of Affected Loans. If the obligation of any Bank to make a Eurodollar Loan or to Continue Eurodollar Loans, or to Convert all or any part of the Base Rate Loan into Eurodollar Loans shall be suspended pursuant to Section 4.1 or hereof, such Bank's Eurodollar Loans shall be automatically Converted into the Base Rate Loan on the last day(s) of the then current Interest Period(s) for such Eurodollar Loans (or, in the case of a Conversion required by Section 4.3 hereof, on such earlier date as such Bank may specify to Borrower with a copy to Administrative Agent) and, unless and until such Bank gives notice as provided below that the circumstances specified in Section 4.1 or 4.3 hereof that gave rise to such Conversion no longer exist: (a) to the extent that such Bank's Eurodollar Loans have been so Converted, all payments and prepayments of principal that would otherwise be applied to such Bank's Eurodollar Loans shall be applied instead to its Commitment Percentage of the Base Rate Loan; and (b) all Loans that would otherwise be made or Continued by such Bank as Eurodollar Loans shall be made or Continued instead as a part of the Base Rate Loan, and all or any part of the Base Rate Loan held by such Bank that would otherwise be Converted into Eurodollar Loans shall remain as part of the Base Rate Loan. If such Bank gives notice to Borrower (with a copy to Administrative Agent) that the circumstances specified in Section 4.1 or 4.3 hereof that gave rise to the Conversion of such Bank's Eurodollar Loans pursuant to this Section 4.4 no longer exist (which such Bank agrees to do promptly upon such circumstances ceasing to exist) at a time when Eurodollar Loans made by other Banks are outstanding, such Bank's portion of the Base Rate Loan shall be automatically Converted, on the first day(s) of the next succeeding Interest Period(s) for such outstanding Eurodollar Loans, to the extent 32 39 necessary so that, after giving effect thereto, all Eurodollar Loans held by Banks holding Eurodollar Loans are held pro rata (as to principal amounts and Interest Periods) in accordance with their respective Commitments. SECTION 4.5 Compensation. Upon the request of any Bank, Borrower shall pay to such Bank such amount or amounts as shall be sufficient (in the reasonable opinion of such Bank) to compensate it for any loss, cost, or expense incurred by it as a result of: (a) any payment, prepayment, or Conversion of a Eurodollar Loan for any reason (including, without limitation, the acceleration of the Loans pursuant to Section 12.1) on a date other than the last day of the Interest Period for such Loan; or (b) any failure by Borrower for any reason (including, without limitation, the failure of any condition precedent specified in Article 7 to be satisfied) to borrow, Convert, Continue, or prepay a Eurodollar Loan on the date for such Borrowing, Conversion, Continuation, or prepayment specified in the relevant Request for Borrowing, or notice of prepayment, Continuation, or Conversion under this Agreement. SECTION 4.6 Taxes. (a) Any and all payments by Borrower to or for the account of any Bank or Administrative Agent hereunder or under any other Loan Paper shall be made free and clear of and without deduction for any and all present or future Taxes, and all liabilities with respect thereto, excluding, in the case of each Bank and Administrative Agent, Taxes imposed on its income, and franchise Taxes imposed on it, by the jurisdiction under the Laws of which such Bank (or its Applicable Lending Office) or Administrative Agent (as the case may be) is organized or any political subdivision thereof. If Borrower shall be required by Law to deduct any Taxes from or in respect of any sum payable under this Agreement or any other Loan Paper to any Bank or Administrative Agent, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 4.6) such Bank or Administrative Agent receives an amount equal to the sum it would have received had no such deductions been made, (ii) Borrower shall make such deductions, (iii) Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable Law, and (iv) Borrower shall furnish to Administrative Agent, at its address set forth on Schedule 1 hereto, the original or a certified copy of a receipt evidencing payment thereof. (b) In addition, Borrower agrees to pay any and all present or future stamp or documentary Taxes and any other excise or property Taxes or charges or similar levies which arise from any payment made under this Agreement or any other Loan Paper or from the execution or delivery of, or otherwise with respect to, this Agreement or any other Loan Paper (hereinafter referred to as "Other Taxes"). 33 40 (c) Borrower agrees to indemnify each Bank and Administrative Agent for the full amount of Taxes and Other Taxes (including, without limitation, any Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section 4.6) paid by such Bank or Administrative Agent (as the case may be) and any liability (including penalties, interest, and expenses) arising therefrom or with respect thereto. (d) Each Bank organized under the Laws of a jurisdiction outside the United States, on or prior to the date of its execution and delivery of this Agreement in the case of each Bank listed on Schedule 1 hereto and on or prior to the date on which it becomes a Bank in the case of each other Bank, and from time to time thereafter if requested in writing by Borrower or Administrative Agent (but only so long as such Bank remains lawfully able to do so), shall provide Borrower and Administrative Agent with (i) Internal Revenue Service Form 1001 or 4224, 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 reduces the rate of 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-8 or 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 Code), certifying that such Bank is entitled to an exemption from or a reduced rate of Tax on payments pursuant to this Agreement or any of the other Loan Papers. (e) For any period with respect to which a Bank has failed to provide Borrower and Administrative Agent with the appropriate form pursuant to Section 4.6(d) (unless such failure is due to a change in treaty, Law, or regulation occurring subsequent to the date on which a form originally was required to be provided), such Bank shall not be entitled to indemnification under Section 4.6(a) or 4.6(b) with respect to Taxes imposed by the United States; provided, however, that should a Bank, which is otherwise exempt from or subject to a reduced rate of withholding Tax, become subject to Taxes because of its failure to deliver a form required hereunder, Borrower shall take such steps as such Bank shall reasonably request to assist such Bank to recover such Taxes. (f) If Borrower is required to pay additional amounts to or for the account of any Bank pursuant to this Section 4.6, then such Bank will agree to use reasonable efforts to change the jurisdiction of its Applicable Lending Office so as to eliminate or reduce any such additional payment which may thereafter accrue if such change, in the judgment of such Bank, is not otherwise disadvantageous to such Bank.

(k) Borrower or any Subsidiary of Borrower shall incur Environmental Liabilities which, individually or when considered in the aggregate, exceed $250,000; 59 66 (l) this Agreement or any other Loan Paper shall cease to be in full force and effect or shall be declared null and void or the validity or enforceability thereof shall be contested or challenged by Borrower or any other Credit Party , or Borrower or any other Credit Party shall deny that it has any further liability or obligation under any of the Loan Papers to which it is a party, or any Lien created by the Loan Papers shall for any reason (other than the release thereof in accordance with the Loan Papers) cease to be a valid, first priority, perfected Lien upon any of the Proved Mineral Interests purported to be covered thereby; (m) a Material Adverse Change shall occur; or (n) a Change of Central shall occur; then, and in every such event, Administrative Agent shall without presentment, notice or demand (unless expressly provided for herein) of any kind (including, without limitation, notice of intention to accelerate and acceleration), all of which are hereby waived, (a) if requested by Required Banks, terminate the Commitments and they shall thereupon terminate, and (b) if requested by Required Banks, take such other actions as may be permitted by the Loan Papers including, declaring the Notes (together with accrued interest thereon) to be, and the Notes shall thereupon become, immediately due and payable; provided that in the case of any of the Events of Default specified in Sections 12.1(g) or 12.1(h), without any notice to Borrower or any other act by Administrative Agent or Banks, the Commitments shall thereupon terminate and the Notes (together with accrued interest thereon) shall become immediately due and payable. ARTICLE 13 AGENTS SECTION 13.1 Appointment, Powers, and Immunities. Each Bank hereby irrevocably appoints and authorizes each Agent to act as its agent under this Agreement and the other Loan Papers with such powers and discretion as are specifically delegated to each such Agent by the terms of this Agreement and the other Loan Papers (and any separate agreements entered into among the parties regarding same), together with such other powers as are reasonably incidental thereto. No Agent (which term as used in this sentence and in Section 13.5 and the first sentence of Section 13.6 hereof shall include their Affiliates and their own and their Affiliates' officers, directors, employees, and agents): (a) shall have any duties or responsibilities except those expressly set forth in this Agreement and the other Loan Papers and no Agent shall be a trustee or fiduciary for any Bank; (b) shall be responsible to Banks for any recital, statement, representation, or warranty (whether written or oral) made in or in connection with any Loan Paper or any certificate or other document referred to or provided for in, or received by any of them under, any Loan Paper, or for the value, validity, effectiveness, genuineness, enforceability, or sufficiency of any Loan Paper, or any other document referred to or provided for therein or for any failure by any Credit Party or any other Person to perform any of its obligations thereunder; (c) shall be responsible for or have any duty to ascertain, inquire into, or verify the performance or observance of any covenants or agreements by any Credit 60 67 Party or the satisfaction of any condition or to inspect the property (including the books and records) of any Credit Party or any of its Subsidiaries or Affiliates; (d) shall be required to initiate or conduct any litigation or collection proceedings under any Loan Paper; and (e) shall be responsible for any action taken or omitted to be taken by it under or in connection with any Loan Paper, except for its own gross negligence or willful misconduct. Each Agent may employ agents and attorneys-in-fact and shall not be responsible for the negligence or misconduct of any such agents or attorneys-in-fact selected by any such Agent with reasonable care. SECTION 13.2 Reliance by Agents. Each Agent shall be entitled to rely upon any certification, notice, instrument, writing, or other communication (including, without limitation, any thereof by telephone or telecopy) believed by it to be genuine and correct and to have been signed, sent or made by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel (including counsel for any Credit Party), independent accountants, and other experts selected by any such Agent. Each Agent may deem and treat the payee of any Note as the holder thereof for all purposes hereof unless and until Administrative Agent receives and accepts an Assignment and Acceptance Agreement executed in accordance with Section 14.10 hereof. As to any matters not expressly provided for by this Agreement, no Agent shall be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of Required Banks, and such instructions shall be binding on Banks; provided, however, that no Agent shall be required to take any action that exposes such Agent to personal liability or that is contrary to any Loan Paper or applicable Law unless it shall first be indemnified to its satisfaction by Banks against any and all liability and expense which may be incurred by it by reason of taking any such action. SECTION 13.3 Defaults. No Agent shall be deemed to have knowledge or notice of the occurrence of a Default or Event of Default unless Administrative Agent has received written notice from a Bank, Parent or Borrower specifying such Default or Event of Default and stating that such notice is a "Notice of Default". In the event that Administrative Agent receives such a notice of the occurrence of a Default or Event of Default, Administrative Agent shall give prompt notice thereof to Banks. Administrative Agent shall (subject to Section 13.2 hereof) take such action with respect to such Default or Event of Default as shall reasonably be directed by Required Banks; provided that, unless and until Administrative Agent shall have received such directions, Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interest of Banks. SECTION 13.4 Rights as Bank. With respect to its Commitment and the Loans made by it, NationsBank (and any successor acting as Administrative Agent) in its capacity as a Bank hereunder shall have the same rights and powers hereunder as any other Bank and may exercise the same as though it were not acting as Administrative Agent, and the term "Bank" or "Banks" shall, unless the context otherwise indicates, include Administrative Agent in its individual capacity. NationsBank (and any successor acting as Administrative Agent), each other Agent and their Affiliates may (without having to account therefor to any Bank) accept deposits from, lend money 61 68 to, make investments in, provide services to, and generally engage in any kind of lending, trust, or other business with any Credit Party or Affiliates as if it were not acting as Agent, and NationsBank (and any successor acting as Administrative Agent), each other Agent and their Affiliates may accept fees and other consideration from any Credit Party or Affiliates for services in connection with this Agreement or otherwise without having to account for the same to Banks. SECTION 13.5 Indemnification. Banks agree to indemnify each Agent (to the extent not reimbursed by Parent and/or Borrower hereof, but without limiting the obligations of Parent and Borrower to so reimburse) ratably in accordance with their respective Commitments, for any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses (including attorneys' fees), or disbursements of any kind and nature whatsoever that may be imposed on, incurred by or asserted against any such Agent (including by any Bank) in any way relating to or arising out of any Loan Paper or the transactions contemplated thereby or any action taken or omitted by any Agent under any Loan Paper (INCLUDING ANY OF THE FOREGOING ARISING FROM THE NEGLIGENCE OF ANY AGENT); provided that no Bank shall be liable for any of the foregoing to the extent they arise from the gross negligence or willful misconduct of the Person to be indemnified. Without limitation of the foregoing, each Bank agrees to reimburse each Agent promptly upon demand for its ratable share of any costs or expenses payable by Parent and/or Borrower hereunder, to the extent that any such Agent is not promptly reimbursed for such costs and expenses by Parent and/or Borrower. The agreements contained in this Section 13.5 shall survive payment and performance in full of the Obligations and all other amounts payable under this Agreement. SECTION 13.6 Non-Reliance on Agents and Other Banks. Each Bank agrees that it has, independently and without reliance on any Agent or any other Bank, and based on such documents and information as it has deemed appropriate, made its own credit analysis of each Credit Party and decision to enter into this Agreement and that it will, independently and without reliance upon any Agent or any other Bank, and based on such documents and information as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under the Loan Papers. Except for notices, reports, and other documents and information expressly required to be furnished to Banks by Administrative Agent hereunder, no Agent shall have any duty or responsibility to provide any Bank with any credit or other information concerning the affairs, financial condition, or business of any Credit Party or their Affiliates that may come into the possession of any such Agent or any of their Affiliates. SECTION 13.7 Resignation of Agents. Any Agent may resign at any time by giving notice thereof to Banks and Borrower. Upon any such resignation, Required Banks shall have the right to appoint a successor Agent. If no successor Agent shall have been so appointed by Required Banks and shall have accepted such appointment within thirty (30) days after the retiring Agent's giving of notice of resignation, then the retiring Agent may, on behalf of Banks, appoint a successor Agent which shall be a commercial bank organized under the Laws of the United States of America having combined capital and surplus of at least $100,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor, such successor shall thereupon succeed to and 62 69 become vested with all the rights, powers, discretion, privileges, and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. After any retiring Agent's resignation hereunder as Agent, the provisions of this Article 13 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Agent. ARTICLE 14 MISCELLANEOUS SECTION 14.1 Notices. All notices, requests and other communications to any party hereunder shall be in writing (including bank wire, telecopy or similar writing) and shall be given, if to Administrative Agent or any Bank, at its address or telecopier number set forth on Schedule 1 hereto, and if given to Borrower, at its address or telecopy number set forth on the signature pages hereof (or in either case, at such other address or telecopy number as such party may hereafter specify for the purpose by notice to the other parties hereto). Each such notice, request or other communication shall be effective (a) if given by telecopy, when such telecopy is transmitted to the telecopy number specified in this Section 14.1 and the appropriate answerback is received or receipt is otherwise confirmed, (b) if given by mail, three (3) Domestic Business Days after deposit in the mails with first class postage prepaid, addressed as aforesaid or (c) if given by any other means, when delivered at the address specified in this Section 14.1; provided that notices to Administrative Agent under Article 2 or 3 shall not be effective until received. SECTION 14.2 No Waivers. No failure or delay by Administrative Agent or any Bank in exercising any right, power or privilege hereunder or under any Note or other Loan Paper shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by Law or in any of the other Loan Papers. SECTION 14.3 Expenses; Indemnification. (a) Borrower agrees to pay on demand all reasonable costs and expenses of Administrative Agent in connection with the syndication, preparation, execution, delivery, modification, and amendment of this Agreement, the other Loan Papers, and the other documents to be delivered hereunder, including, without limitation, the reasonable fees and expenses of counsel for Administrative Agent (including the cost of internal counsel) with respect thereto and with respect to advising Administrative Agent as to its rights and responsibilities under the Loan Papers. Borrower further agrees to pay on demand all reasonable costs and expenses of Administrative Agent and Banks, if any (including, without limitation, reasonable attorneys' fees and expenses and the cost of internal counsel), in connection with the enforcement (whether through negotiations, legal proceedings, or otherwise) of the Loan Papers and the other documents to be delivered hereunder. 63 70 (b) Borrower agrees to indemnify and hold harmless Administrative Agent and each Bank and each of their Affiliates and their respective officers, directors, employees, Administrative Agents, and advisors (each, an "Indemnified Party") from and against any and all claims, damages, losses, liabilities, costs, and expenses (including, without limitation, reasonable attorneys' fees) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or by reason of (including, without limitation, in connection with any investigation, litigation, or proceeding or preparation of defense in connection therewith) the Loan Papers, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Revolving Loan (INCLUDING ANY OF THE FOREGOING ARISING FROM THE NEGLIGENCE OF THE INDEMNIFIED PARTY), except to the extent such claim, damage, loss, liability, cost, or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party's gross negligence or willful misconduct. In the case of an investigation, litigation or other proceeding to which the indemnity in this Section 14.3 applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by Borrower, its directors, shareholders or creditors or an Indemnified Party or any other Person or any Indemnified Party is otherwise a party thereto and whether or not the transactions contemplated hereby are consummated. Borrower agrees not to assert any claim against Administrative Agent, any Bank, any of their Affiliates, or any of their respective directors, officers, employees, attorneys, Administrative Agents, and advisers, on any theory of liability, for special, indirect, consequential, or punitive damages arising out of or otherwise relating to the Loan Papers, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Revolving Loan. (c) Without prejudice to the survival of any other agreement of Borrower hereunder, the agreements and obligations of Borrower contained in this Section 14.3 shall survive the payment in full of the Loans and all other amounts payable under this Agreement. SECTION 14.4 Right of Set-off; Adjustments. (a) Upon the occurrence and during the continuance of any Event of Default, each Bank (and each of its Affiliates) is hereby authorized at any time and from time to time, to the fullest extent permitted by Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Bank (or any of its Affiliates) to or for the credit or the account of Borrower against any and all of the Obligations, irrespective of whether such Bank shall have made any demand under this Agreement or Note held by such and although such obligations may be unmatured. Each Bank agrees promptly to notify Borrower after any such set-off and application made by such Bank; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Bank under this Section 14.4 are in addition to other rights and remedies (including, without limitation, other rights of set-off) that such Bank may have. (b) If any Bank (a "benefitted Bank") shall at any time receive any payment of all or part of the Loans owing to it, or interest thereon, or receive any collateral in respect thereof 64 71 (whether voluntarily or involuntarily, by set-off, or otherwise), in a greater proportion than any such payment to or collateral received by any other Bank, if any, in respect of such other Bank's Loans owing to it, or interest thereon, such benefitted Bank shall purchase for cash from the other Banks a participating interest in such portion of each such other Bank's Loans owing to it, or shall provide such other Banks with the benefits of any such collateral, or the proceeds thereof, as shall be necessary to cause such benefitted Bank to share the excess payment or benefits of such collateral or proceeds ratably with each Banks; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such benefitted Bank, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest. Borrower agrees that any Bank so purchasing a participation from a Bank pursuant to this Section 14.4 may, to the fullest extent permitted by Law, exercise all of its rights of payment (including the right of set-off) with respect to such participation as fully as if such Person were the direct creditor of Borrower in the amount of such participation. SECTION 14.5 Amendments and Waivers. Any provision of this Agreement or any other Loan Paper may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by Borrower and the Required Banks (and, if Article 13 or the rights or duties of any Agent are affected thereby, by such Agent); provided that no such amendment or waiver shall, unless signed by each Bank directly affected thereby, (i) increase the Commitments of Banks, (ii) reduce the principal of or rate of interest on any Loan or any fees or other amounts payable hereunder, (iii) postpone any date fixed for the payment of any scheduled installment of principal of or interest on any Loan or any fees or other amounts payable hereunder or for termination of any Commitment, (iv) change the percentage of the Commitments or of the unpaid principal amount of the Notes, or the number of Banks, which shall be required for Banks or any of them to take any action under this Section 14.5 or any other provision of this Agreement, or (v) release any guarantor of the Obligations or all or substantially all of the collateral securing the Obligations. SECTION 14.6 Survival. All representations, warranties and covenants made by Borrower or any of its Subsidiaries herein or in any certificate or other instrument delivered by it or in its behalf under the Loan Papers shall be considered to have been relied upon by Banks and shall survive the delivery to Banks of such Loan Papers or the extension of the Loans (or any part thereof), regardless of any investigation made by or on behalf of Banks. The indemnity provided in Section 14.3 herein shall survive the repayment of all credit advances hereunder and/or the discharge or release of any Lien granted hereunder or in any other Loan Paper, contract or agreement between Borrower or any of its Subsidiaries and Administrative Agent or any Bank. SECTION 14.7 Limitation on Interest. Regardless of any provision contained in the Loan Papers, Banks shall never be entitled to receive, collect, or apply, as interest on the Revolving Loan, any amount in excess of the Maximum Lawful Rate, and in the event any Bank ever receives, collects or applies as interest any such excess, such amount which would be deemed excessive interest shall be deemed a partial prepayment of principal and treated hereunder as such; and if the Revolving Loan is paid in full, any remaining excess shall promptly be paid to Borrower. In determining whether or not the interest paid or payable under any specific contingency exceeds the Maximum Lawful Rate, 65 72 Borrower and Banks shall, to the extent permitted under applicable Law, (a) characterize any nonprincipal payment as an expense, fee or premium rather than as interest, (b) exclude voluntary prepayments and the effects thereof and (c) amortize, prorate, allocate and spread, in equal parts, the total amount of the interest throughout the entire contemplated term of the Notes, so that the interest rate is the Maximum Lawful Rate throughout the entire term of the Notes; provided, however, that if the unpaid principal balance thereof is paid and performed in full prior to the end of the full contemplated term thereof, and if the interest received for the actual period of existence thereof exceeds the Maximum Lawful Rate, Banks shall refund to Borrower the amount of such excess and, in such event, Banks shall not be subject to any penalties provided by any laws for contracting for, charging, taking, reserving or receiving interest in excess of the Maximum Lawful Rate. SECTION 14.8 Invalid Provisions. If any provision of the Loan Papers is held to be illegal, invalid, or unenforceable under present or future Laws effective during the term thereof, such provision shall be fully severable, the Loan Papers shall be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part thereof, and the remaining provisions thereof shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance therefrom. Furthermore, in lieu of such illegal, invalid, or unenforceable provision there shall be added automatically as a part of the Loan Papers a provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible and be legal, valid and enforceable. SECTION 14.9 Waiver of Consumer Credit Laws. Pursuant to Article 15.10(b) of Chapter 15, Subtitle 79, Revised Civil Statutes of Texas, 1925, as amended, Borrower agrees that such Chapter 15 shall not govern or in any manner apply to the Revolving Loan. SECTION 14.10 Assignments and Participations. (a) Each Bank may assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its interest in the Revolving Loan, its Note, and its Commitment); provided, however, that (i) each such assignment shall be to an Eligible Assignee; (ii) except in the case of an assignment to another Bank or an assignment of all of a Bank's rights and obligations under this Agreement, any such partial assignment shall be in an amount at least equal to $5,000,000 or an integral multiple of $100,000 in excess thereof; (iii) each such assignment by a Bank shall be of a constant, and not varying, percentage of all of its rights and obligations under this Agreement and its Note; and (iv) the parties to such assignment shall execute and deliver to Administrative Agent for its acceptance an Assignment and Acceptance Agreement (herein so called) 66 73 in the form of Exhibit K hereto, together with any Note subject to such assignment and a processing fee of $3,500. Upon execution, delivery, and acceptance of such Assignment and Acceptance Agreement, the assignee thereunder shall be a party hereto and, to the extent of such assignment, have the obligations, rights, and benefits of a Bank hereunder and the assigning Bank shall, to the extent of such assignment, relinquish its rights and be released from its obligations under this Agreement. Upon the consummation of any assignment pursuant to this Section 14.10(a), the assignor, Administrative Agent and Borrower shall make appropriate arrangements so that, if required, new Notes are issued to the assignor and the assignee. If the assignee is not incorporated under the Laws of the United States of America or a state thereof, it shall deliver to Borrower and Administrative Agent certification as to exemption from deduction or withholding of Taxes in accordance with Section 4.6(d). (b) Administrative Agent shall maintain at its address set forth on Schedule 1 hereto, a copy of each Assignment and Acceptance Agreement delivered to and accepted by it and a register for the recordation of the names and addresses of Banks and the Commitment of, and principal amount of the Revolving Loan owing to, each Bank and the Commitment Percentage of each Bank from time to time (the "Register"). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and Borrower, Administrative Agent and Banks may treat each Person whose name is recorded in the Register as a Bank hereunder for all purposes of this Agreement. The Register shall be available for inspection by Borrower or any Bank at any reasonable time and from time to time upon reasonable prior notice. (c) Upon its receipt of an Assignment and Acceptance Agreement executed by the parties thereto, together with any Note subject to such assignment and payment of the processing fee, Administrative Agent shall, if such Assignment and Acceptance Agreement has been completed and is in substantially the form of Exhibit K hereto, (i) accept such Assignment and Acceptance Agreement, (ii) record the information contained therein in the Register, and (iii) give prompt notice thereof to the parties thereto. (d) Each Bank may sell participations to one or more Persons in all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and its interest in the Revolving Loan); provided, however, that (i) such Bank's obligations under this Agreement shall remain unchanged, (ii) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the participant shall be entitled to the benefit of the yield protection provisions contained in Article 4 and the right of set-off contained in Section 14.4, and (iv) Borrower shall continue to deal solely and directly with such Bank in connection with such Bank's rights and obligations under this Agreement, and such Bank shall retain the sole right to enforce the obligations of Borrower relating to its interest in the Revolving Loan and its Note and to approve any amendment, modification, or waiver of any provision of this Agreement (other than amendments, modifications, or waivers decreasing the amount of principal of or the rate at which interest is payable on the Revolving Loan or Note, extending any scheduled principal payment date 67 74 or date fixed for the payment of interest on the Revolving Loan or Note, or extending its Commitment). (e) Notwithstanding any other provision set forth in this Agreement, any Bank may at any time assign and pledge all or any portion of its interest in the Revolving Loan and its Note to any Federal Reserve Bank as collateral security pursuant to Regulation A and any Operating Circular issued by such Federal Reserve Bank. No such assignment shall release the assigning Bank from its obligations hereunder. (f) Any Bank may furnish any information concerning Borrower or any of its Subsidiaries in the possession of such Bank from time to time to assignees and participants (including prospective assignees and participants). (g) Borrower shall not assign or transfer any rights or obligations under any Loan Paper or permit any Credit Party to assign or transfer any rights or obligations under any Loan Paper without first obtaining all Banks' consent, and any purported assignment or transfer without all Bank's consent is void. SECTION 14.11 TEXAS LAW. THIS AGREEMENT, EACH NOTE AND THE OTHER LOAN PAPERS SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS AND THE LAWS OF THE UNITED STATES OF AMERICA, EXCEPT TO THE EXTENT THAT THE LAWS OF ANY STATE IN WHICH ANY PROPERTY INTENDED AS SECURITY FOR THE OBLIGATIONS IS LOCATED NECESSARILY GOVERN (A) THE PERFECTION AND PRIORITY OF THE LIENS IN FAVOR OF ADMINISTRATIVE AGENT AND BANKS WITH RESPECT TO SUCH PROPERTY, AND (B) THE EXERCISE OF ANY REMEDIES (INCLUDING FORECLOSURE) WITH RESPECT TO SUCH PROPERTY. SECTION 14.12 Consent to Jurisdiction; Waiver of Immunities. (a) Borrower hereby irrevocably submits to the jurisdiction of any Texas State or Federal court sitting in the Northern District of Texas over any action or proceeding arising out of or relating to this Agreement or any other Loan Papers, and Borrower hereby irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such Texas State or Federal court. As an alternative, Borrower irrevocably consents to the service of any and all process in any such action or proceeding by the mailing of copies of such process to such Person at its address specified in Section 14.1. Borrower agrees that a final unappealable judgment on any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. (b) Nothing in this Section 14.12 shall affect any right of Banks to serve legal process in any other manner permitted by law or affect the right of any Bank to bring any action or 68 75 proceeding against Borrower or its Subsidiaries or their respective properties in the courts of any other jurisdictions. (c) To the extent that Borrower has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, Borrower hereby irrevocably waives such immunity in respect of its obligations under this Agreement and the other Loan Papers. SECTION 14.13 Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when Administrative Agent shall have received counterparts hereof signed by all of the parties hereto or, in the case of any Bank as to which an executed counterpart shall not have been received, Administrative Agent shall have received telegraphic or other written confirmation from such Bank of execution of a counterpart hereof by such Bank. SECTION 14.14 No Third Party Beneficiaries. It is expressly intended that there shall be no third party beneficiaries of the covenants, agreements, representations or warranties herein contained other than third party beneficiaries permitted pursuant to Section 14.10.

Wilson Title: Managing Director 78 EXHIBIT A FACILITY GUARANTY THIS FACILITY GUARANTY (this "Guaranty") is dated as of the ____ day of __________, ____, by [ , A ____________] ("Guarantor"), in favor of NATIONSBANK, N.A. (NationsBank, N.A., acting as a Bank but not as Administrative Agent, and each of its successors and assigns are collectively referred to herein as "Noteholders"). W I T N E S S E T H: WHEREAS, EXUS Energy, LLC ("Borrower"), NationsBank, N.A., as Administrative Agent ("Administrative Agent") and the financial institutions parties thereto as Banks, are parties to that certain Credit Agreement (as from time to time amended, the "Agreement") dated as of June 30, 1999, pursuant to which Noteholders have made a revolving credit loan to Borrower and agreed to issue and participate in letters of credit issued on behalf of Borrower (unless otherwise defined herein, all terms used herein with their initial letter capitalized shall have the meaning given such terms in the Agreement); and WHEREAS, Noteholders have required, as a condition to the extension and/or the continued extension of credit under the Agreement, that Guarantor execute and deliver this Guaranty; and WHEREAS, Guarantor has determined that valuable benefits will be derived by it as a result of the Agreement and the extension of credit made (and/or to be made) by Noteholders thereunder; and WHEREAS, Guarantor has further determined that the benefits accruing to it from the Agreement exceed Guarantor's anticipated liability under this Guaranty. NOW, THEREFORE, for valuable consideration, the receipt and sufficiency of which are hereby acknowledged and confessed, Guarantor hereby covenants and agrees as follows: 15. Guarantor hereby absolutely and unconditionally guarantees the prompt, complete and full payment when due, no matter how such shall become due, of the Obligations, and further guarantees that Borrower will properly and timely perform the Obligations. Notwithstanding any contrary provision in this Guaranty, however, Guarantor's maximum liability under this Guaranty is limited, to the extent, if any, required so that its liability is not subject to avoidance under applicable Debtor Relief Laws (as such term is defined in Paragraph 8 hereof). [PRECEDING SENTENCE WILL NOT BE INCLUDED IN FACILITY GUARANTEES EXECUTED BY VENUS AND EXCO.] A-1 79 16. If Guarantor is or becomes liable for any indebtedness owing by Borrower to any Noteholder by endorsement or otherwise than under this Guaranty, such liability shall not be in any manner impaired or affected hereby, and the rights of Noteholders hereunder shall be cumulative of any and all other rights that Noteholders may ever have against Guarantor. The exercise by any Noteholder of any right or remedy hereunder or under any other instrument, at law or in equity, shall not preclude the concurrent or subsequent exercise of any other right or remedy. 17. In the event of default by Borrower in payment of the Obligations, or any part thereof, when such Obligations become due, either by their terms or as the result of the exercise of any power to accelerate, Guarantor shall, on demand, and without further notice of dishonor and without any notice having been given to Guarantor previous to such demand of the acceptance by Noteholders of this Guaranty, and without any notice having been given to such Guarantor previous to such demand of the creating or incurring of such Obligations, pay the amount due thereon to Noteholders at Administrative Agent's office as set forth in the Agreement, and it shall not be necessary for any Noteholder, in order to enforce such payment by Guarantor, first, to institute suit or exhaust its remedies against Borrower or others liable on such Obligations, to have Borrower joined with Guarantor in any suit brought under this Guaranty or to enforce their rights against any security which shall ever have been given to secure such indebtedness; provided, however, that in the event any Noteholder elects to enforce and/or exercise any remedies they may possess with respect to any security for the Obligations prior to demanding payment from Guarantor, Guarantor shall nevertheless be obligated hereunder for any and all sums still owing to Noteholders on the Obligations and not repaid or recovered incident to the exercise of such remedies. 18. Notice to Guarantor of the acceptance of this Guaranty and of the making, renewing or assignment of the Obligations and each item thereof, are hereby expressly waived by Guarantor. 19. Each payment on the Obligations shall be deemed to have been made by Borrower unless express written notice is given to Noteholders at the time of such payment that such payment is made by Guarantor as specified in such notice. 20. If all or any part of the Obligations at any time are secured, Guarantor agrees that Administrative Agent and/or Noteholders may at any time and from time to time, at their discretion and with or without valuable consideration, allow substitution or withdrawal of collateral or other security and release collateral or other security or compromise or settle any amount due or owing under the Agreement or amend or modify in whole or in part the Agreement or any Loan Paper executed in connection with same without impairing or diminishing the obligations of Guarantor hereunder. Guarantor further agrees that if Borrower executes in favor of any Noteholder any collateral agreement, mortgage or other security instrument, the exercise by any Noteholder of any right or remedy thereby conferred on such Noteholder shall be wholly discretionary with such Noteholder, and that the exercise or failure to exercise any such right or remedy shall in no way impair or diminish the obligation of Guarantor hereunder. Guarantor further agrees that Noteholders and Administrative Agent shall not be liable for their failure to use diligence in the collection of the Obligations or in preserving the liability of any Person liable for the Obligations, and Guarantor A-2 80 hereby waives presentment for payment, notice of nonpayment, protest and notice thereof (including, notice of acceleration), and diligence in bringing suits against any Person liable on the Obligations, or any part thereof. 21. Guarantor agrees that Noteholders, in their discretion, may a) bring suit against all guarantors (including, without limitation, Guarantor hereunder) of the Obligations jointly and severally or against any one or more of them, b) compound or settle with any one or more of such guarantors for such consideration as Noteholders may deem proper, and c) release one or more of such guarantors from liability hereunder, and that no such action shall impair the rights of Noteholders to collect the Obligations (or the unpaid balance thereof) from other such guarantors of the Obligations, or any of them, not so sued, settled with or released. Guarantor agrees, however, that nothing contained in this paragraph, and no action by Noteholders permitted under this paragraph, shall in any way affect or impair the rights or obligations of such guarantors among themselves. 22. Guarantor represents and warrants to each Noteholder that a) Guarantor is a corporation, limited liability company or partnership duly organized and validly existing under the laws of the jurisdiction of its incorporation or formation; and b) Guarantor possesses all requisite authority and power to authorize, execute, deliver and comply with the terms of this Guaranty; this Guaranty has been duly authorized and approved by all necessary action on the part of Guarantor and constitutes a valid and binding obligation of Guarantor enforceable in accordance with its terms, except as the enforcement thereof may be limited by applicable Debtor Relief Laws; and no approval or consent of any court or governmental entity is required for the authorization, execution, delivery or compliance with this Guaranty which has not been obtained (and copies thereof delivered to Noteholders). As used in this Guaranty, the term "Debtor Relief Laws" means the Bankruptcy Code of the United States of America and all other applicable liquidation, conservatorship, bankruptcy, moratorium, rearrangement, receivership, insolvency, reorganization, suspension of payments or similar debtor relief Laws from time to time in effect affecting the rights of creditors generally. 23. Guarantor covenants and agrees that until the Obligations are paid and performed in full, except as otherwise provided in the Agreement or unless Noteholders give their prior written consent to any deviation therefrom, it will a) at all times maintain its existence and authority to transact business in any State or jurisdiction where Guarantor has assets and operations, b) promptly deliver to Noteholders and to Administrative Agent such information respecting its business affairs, assets and liabilities as Noteholders may reasonably request, and c) duly and punctually observe and perform all covenants applicable to Guarantor under the Agreement and the other Loan Papers. The failure of Guarantor to comply with the terms of this paragraph shall be an Event of Default under the Agreement. 24. This Guaranty is for the benefit of Noteholders, their successors and assigns, and in the event of an assignment by Noteholders (or their successors or assigns) of the Obligations, or any part thereof, the rights and benefits hereunder, to the extent applicable to the Obligations so assigned, A-3 81 may be transferred with such Obligations. This Guaranty is binding upon Guarantor and its successors and assigns. 25. No modification, consent, amendment or waiver of any provision of this Guaranty, nor consent to any departure by Guarantor therefrom, shall be effective unless the same shall be in writing and signed by each Noteholder, and then shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on Guarantor in any case shall, of itself, entitle Guarantor to any other or further notice or demand in similar or other circumstances. No delay or omission by Noteholders in exercising any power or right hereunder shall impair any such right or power or be construed as a waiver thereof or any acquiescence therein, nor shall any single or partial exercise of any such power preclude other or further exercise thereof, or the exercise of any other right or power hereunder. All rights and remedies of Noteholders hereunder are cumulative of each other and of every other right or remedy which Noteholders may otherwise have at law or in equity or under any other contract or document, and the exercise of one or more rights or remedies shall not prejudice or impair the concurrent or subsequent exercise of other rights or remedies. 26. No provision herein or in any promissory note, instrument or any other Loan Paper executed by Borrower or Guarantor evidencing the Obligations shall require the payment or permit the collection of interest in excess of the Maximum Lawful Rate. If any excess of interest in such respect is provided for herein or in any such promissory note, instrument, or any other Loan Paper, the provisions of this paragraph shall govern, and neither Borrower nor Guarantor shall be obligated to pay the amount of such interest to the extent that it is in excess of the amount permitted by law. The intention of the parties being to conform strictly to any applicable federal or state usury Laws now in force, all promissory notes, instruments and other Loan Papers executed by Borrower or Guarantor evidencing the Obligations shall be held subject to reduction to the amount allowed under said usury Laws as now or hereafter construed by the courts having jurisdiction. 27. If Guarantor should breach or fail to perform any provision of this Guaranty, Guarantor agrees to pay Noteholders all costs and expenses (including court costs and reasonable attorneys fees) incurred by Noteholders in the enforcement hereof. 28. (a) The liability of Guarantor under this Guaranty shall in no manner be impaired, affected or released by the insolvency, bankruptcy, making of an assignment for the benefit of creditors, arrangement, compensation, composition or readjustment of Borrower, or any proceedings affecting the status, existence or assets of Borrower or other similar proceedings instituted by or against Borrower and affecting the assets of Borrower. (b) Guarantor acknowledges and agrees that any interest on any portion of the Obligations which accrues after the commencement of any proceeding referred to in clause (a) above (or, if interest on any portion of the Obligations ceases to accrue by operation of law by reason of the commencement of said proceeding, such interest as would have accrued on such portion of the Obligations if said proceedings had not been commenced) shall be included in the Obligations because it is the intention of Guarantor, Administrative Agent and Noteholders that the Obligations which are A-4 82 guaranteed by Guarantor pursuant to this Guaranty should be determined without regard to any rule of law or order which may relieve Borrower of any portion of such Obligations. Guarantor will permit any trustee in bankruptcy, receiver, debtor in possession, assignee for the benefit of creditors or similar Person to pay Noteholders or Administrative Agent, or allow the claim of Noteholders or Administrative Agent in respect of, any such interest accruing after the date on which such proceeding is commenced. (c) In the event that all or any portion of the Obligations are paid by Borrower, the obligations of Guarantor hereunder shall continue and remain in full force and effect or be reinstated, as the case may be, in the event that all or any part of such payment(s) are rescinded or recovered directly or indirectly from Administrative Agent or any Noteholder as a preference, fraudulent transfer or otherwise, and any such payments which are so rescinded or recovered shall constitute Obligations for all purposes under this Guaranty. 29. Guarantor understands and agrees that any amounts of Guarantor on account with any Noteholder may be offset to satisfy the obligations of Guarantor hereunder. 30. Guarantor hereby subordinates and makes inferior any and all indebtedness now or at any time hereafter owed by Borrower to Guarantor to the Obligations evidenced by the Agreement and agrees after the occurrence of a Default or Event of Default under the Agreement, not to permit Borrower to repay, or to accept payment from Borrower of, such indebtedness or any part thereof without the prior written consent of Noteholders. Without limiting the foregoing, Guarantor hereby acknowledges and agrees that it will not accept from Borrower or any of its Subsidiaries any, distribution, dividend, reimbursement, repayment, payment or transfer of cash or assets of any type which is prohibited under or pursuant to the terms of the Agreement (a "Prohibited Payment") and to the extent any such Prohibited Payment is received by Guarantor, Guarantor will hold the same in trust for the benefit of the Noteholders and promptly pay the same to Administrative Agent for application to the Obligations. 31. During the period that Noteholders have any commitment to lend or participate in Letter of Credit Exposure under the Loan Papers, or any amount payable under any Note remains unpaid or any Letter of Credit remains outstanding, and throughout any additional preferential period subsequent thereto, Guarantor hereby waives any and all rights of subrogation to which Guarantor may otherwise be entitled against Borrower, or any other guarantor of the Obligations, as a result of any payment made by Guarantor pursuant to this Guaranty. 32. As of the date hereof, the fair saleable value of the property of Guarantor is greater than the total amount of liabilities (including contingent and unliquidated liabilities) of Guarantor, and Guarantor is able to pay all of its liabilities as such liabilities mature and Guarantor does not have unreasonably small capital within the meaning of Section 548, Title 11, United States Code, as amended. In computing the amount of contingent or liquidated liabilities, such liabilities have been computed at the amount which, in light of all the facts and circumstances existing as of the date A-5 83 hereof, represents the amount that can reasonably be expected to become an actual or matured liability. 33. If any provision of this Guaranty is held to be illegal, invalid, or unenforceable, such provision shall be fully severable; this Guaranty shall be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part hereof; and the remaining provisions hereof shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance herefrom. Furthermore, in lieu of such illegal, invalid, or unenforceable provision there shall be added automatically as a part of this Guaranty a provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible and be legal, valid and enforceable. 34. (a) Except to the extent required for the exercise of the remedies provided in the other security instruments, Guarantor hereby irrevocably submits to the nonexclusive jurisdiction of any Texas state or federal court over any action or proceeding arising out of or relating to this Guaranty or any other Loan Paper, and Guarantor hereby irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such Texas state or federal court. Guarantor hereby irrevocably waives, to the fullest extent permitted by Law, any objection which it may now or hereafter have to the laying of venue of any Litigation (as hereinafter defined) arising out of or in connection with this Guaranty or any of the Loan Papers brought in district courts of Dallas County, Texas, or in the United States District Court for the Northern District of Texas, Dallas Division. Guarantor hereby irrevocably waives any claim that any Litigation brought in any such court has been brought in an inconvenient forum. Guarantor hereby irrevocably consents to the service of process out of any of the aforementioned courts in any such Litigation by the mailing of copies thereof by certified mail, return receipt requested, postage prepaid, to Guarantor's office at __________________________________________. Guarantor irrevocably agrees that any legal proceeding against Noteholders shall be brought in the district courts of Dallas County, Texas, or in the United States District Court for the Northern District of Texas, Dallas Division. Nothing herein shall affect the right of any Noteholder to commence legal proceedings or otherwise proceed against Guarantor in any jurisdiction or to serve process in any manner permitted by applicable Law. As used herein, the term "Litigation" means any proceeding, claim, lawsuit or investigation (1) conducted or threatened by or before any court or governmental department, commission, board, bureau, agency or instrumentality of the United States or of any state, commonwealth, nation, territory, possession, county, parish, or municipality, whether now or hereafter constituted or existing, or (2) pending before any public or private arbitration board or panel. (b) Nothing in this Paragraph 20 shall affect any right of any Noteholder to serve legal process in any other manner permitted by Law or affect the right of any Noteholder to bring any action or proceeding against Guarantor in the courts of any other jurisdictions. A-6 84 (c) To the extent that Guarantor has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, Guarantor hereby irrevocably waives such immunity in respect of its obligations under this Guaranty and the other Loan Papers. 35. THIS GUARANTY AND THE OTHER LOAN PAPERS COLLECTIVELY REPRESENT THE FINAL AGREEMENT BY AND AMONG NOTEHOLDERS, ADMINISTRATIVE AGENT, AND GUARANTOR AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF NOTEHOLDERS, ADMINISTRATIVE AGENT, AND GUARANTOR. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG NOTEHOLDERS, ADMINISTRATIVE AGENT, AND GUARANTOR. 36. GUARANTOR, FOR ITSELF, ITS SUCCESSORS AND ASSIGNS, HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ITS RIGHT TO A JURY TRIAL, IN ANY LITIGATION ARISING OUT OF OR IN CONNECTION WITH THIS GUARANTY OR ANY OF THE OTHER LOAN PAPERS. 37. THIS GUARANTY AND THE OTHER LOAN PAPERS SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS. EXECUTED and effective as of the date first above written.

The entire outstanding principal balance hereof and all accrued but unpaid interest thereon shall be due and payable in full on the Termination Date. Upon and subject to the terms and conditions of the Agreement, Borrower shall be entitled to prepay the principal of or interest on this Note from time to time and at any time, in whole or in part. Upon the occurrence and continuance of an Event of Default, and upon the conditions stated in the Agreement, Administrative Agent may, at its option, and shall, to the extent required in accordance with the terms of the Agreement, declare the entire unpaid principal of and accrued interest on this Note immediately due and payable (provided that, upon the occurrence of certain Events of Default, and upon the conditions stated in the Agreement, such acceleration shall be automatic), without notice (except as otherwise required by the Agreement), demand, or presentment, all of which are hereby waived, and the holder hereof shall have the right to offset against this Note any sum or sums owed by the holder hereof to Borrower.

Notwithstanding the foregoing, if at any time, any rate of interest calculated under Section 2.3 of the Agreement (the "Contract Rate") exceeds the Maximum Lawful Rate, the rate of interest hereunder shall be limited to the Maximum Lawful Rate, but any subsequent reductions in the Contract Rate shall not reduce the rate of interest on this Note below the Maximum Lawful Rate until the total amount of interest accrued equals the amount of interest which would have accrued (including the amount of interest which would have accrued prior to the payment or prepayment of any portion of this Note) if the Contract Rate had at all times been in effect. In the event that at maturity (stated or by acceleration), or at final payment of this Note, the total amount of interest paid or accrued on this Note is less than the amount of interest which would have accrued if the Contract Rate had at all times been in effect with respect thereto, then at such time Borrower shall pay to the holder of this Note an amount equal to the difference between (a) the lesser of the amount of interest which would have accrued if the Contract Rate had at all times been in effect and the amount of interest which would have accrued if the Maximum Lawful Rate had at all times been in effect, and (b) the amount of interest actually paid or accrued on this Note.

Secured Party's Appointment as Attorney-in-Fact. (a) Powers. Debtor hereby irrevocably constitutes and appoints Secured Party and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of Debtor and in the name of Debtor or in its own name, from time to time in Secured Party's discretion, for the purpose of carrying out the terms of this Agreement, but only during the existence of an Event of Default, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or D-11 100 desirable to accomplish the purposes of this Agreement, and, without limiting the generality of the foregoing, Debtor hereby gives Secured Party the power and right, on behalf of Debtor, without notice to or assent by Debtor, but only during the existence of an Event of Default, to do the following: (1) in the case of any Collateral in the name of Debtor or its own name, or otherwise, to take possession of and indorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of monies due under, or with respect to, any Collateral and to file any claim or to take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by Secured Party for the purpose of collecting any and all such monies due or with respect to such Collateral whenever payable; (2) to pay or discharge Taxes and Liens, other than Permitted Encumbrances, levied or placed on or threatened against the Collateral, to effect any repairs or any insurance called for by the terms of this Agreement and to pay all or any part of the premiums therefor and the costs thereof; and (3) (a) to direct any party liable for any payment under any of the Collateral to make payment of any and all monies due or to become due thereunder directly to Secured Party or as Secured Party shall direct; (b) to ask or demand for, collect, receive payment of and receipt for, any and all monies, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral; (c) to sign and indorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against debtors, assignments, verifications, notices and other documents in connection with any of the Collateral; (d) to commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any portion thereof and to enforce any other right in respect of any Collateral; (e) to defend any suit, action or proceeding brought against Debtor with respect to any Collateral; (f) to settle, compromise or adjust any suit, action or proceeding described in the preceding clause and, in connection therewith, to give such discharges or releases as Secured Party may deem appropriate; (g) to assign any Trademark (along with the goodwill of the business to which any such Trademark pertains), throughout the world for such term or terms, on such conditions, and in such manner, as Secured Party shall in its sole discretion determine; and (h) generally, to sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though Secured Party were the absolute owner thereof for all purposes, and to do, at Secured Party's option and Debtor's expense, at any time, or from time to time, all acts and things which Secured Party deems necessary to protect, preserve or realize upon the Collateral and to effect the intent of this Agreement, all as fully and effectively as Debtor might do. D-12 101 Debtor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. This power of attorney is power coupled with an interest and shall be irrevocable until the Obligations shall have been paid in full or this Agreement shall have been terminated. (b) Other Powers. Debtor also authorizes Secured Party, at any time and from time to time, during the continuance of an Event of Default, to execute, in connection with the sale provided for in this Section 6, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral. (c) No Duty on the Part of Secured Party. The powers conferred on Secured Party hereunder are solely to protect the interests of Secured Party and the Banks in the Collateral and shall not impose any duty upon Secured Party or any Bank to exercise any such powers. The Banks shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and no Bank nor any Bank's officers, directors, employees or agents shall be responsible to Debtor for any act or failure to act hereunder, except for its own gross negligence or willful misconduct, it being the intent of the parties hereto that Secured Party shall not be accountable for its own negligence. 7. Performance by Secured Party of Company's Obligations. If Debtor fails to perform or comply with any of its agreements contained herein and Secured Party, as provided for by the terms of this Agreement, or any Bank shall itself perform or comply, or otherwise cause performance or compliance, with such agreement, the expenses of Secured Party and any such Bank incurred in connection with such performance or compliance, together with interest thereon at the Maximum Lawful Rate on demand shall be payable by Debtor to Secured Party, and shall constitute obligations secured hereby. 8. Proceeds. Upon request of Secured Party, during the continuance of an Event of Default (a) all Proceeds received by Debtor consisting of cash, checks and other non-cash items shall be held by Debtor in trust for Secured Party, segregated from other funds of Debtor and shall, forthwith upon receipt by Debtor be turned over to Secured Party for the ratable benefit of the Banks in the exact form received by Debtor (duly endorsed by Debtor to Secured Party, if required), and (b) any and all such Proceeds received by Secured Party (whether from Debtor or otherwise) may, in the sole discretion of Secured Party, be held by Secured Party as collateral security for, and/or then or at any time thereafter may be applied by Secured Party against, the Obligations (whether matured or unmatured), such application to be in such order as Secured Party shall elect. Any balance of such Proceeds remaining after the Obligations shall have been paid in full shall be paid over to Debtor or to whomsoever may be lawfully entitled to receive the same. 9. Remedies. (a) General. If an Event of Default shall occur and be continuing, Secured Party may exercise, in addition to all other rights and remedies granted to it in this Agreement and in the other Loan Papers, all rights and remedies of a secured party under the UCC. Without limiting the generality of D-13 102 the foregoing, or any other right available to Secured Party hereunder, Secured Party, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon Debtor or any other party (all and each of which demands, offenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker's board or office of Secured Party or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. Secured Party and each Bank shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in Debtor, which right or equity is hereby waived and released. Debtor further agrees, at Secured Party's request, to assemble, or cause the assembly of, the Collateral and make it available to Secured Party at places which Secured Party shall reasonably select, whether at Debtor's premises or elsewhere. Secured Party shall apply the net Proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of Secured Party hereunder, including, without limitation, reasonable attorneys' fees and disbursements, to the payment in whole or in part of the Obligations, in the manner provided by the Credit Agreement, and only after such application and after the payment by Secured Party of any other amount required by any provision of law, need Secured Party account for the surplus, if any, to Debtor. To the extent permitted by applicable law, Debtor waives all claims, damages and demands it may acquire against Secured Party arising out of the exercise by them of any rights hereunder. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least five (5) days before such sale or other disposition. Debtor shall remain liable for any deficiency if the Proceeds of any sale or other disposition of the Collateral are insufficient to pay the Obligations and the fees and disbursements of any attorneys employed by Secured Party to collect such deficiency. 10. Secured Party's Responsibility With Respect to Collateral. Neither Secured Party nor any Bank shall have any duty to fix or preserve rights against prior parties to the Collateral, and neither Secured Party nor any Bank shall ever be liable for failure to use diligence to collect any amount payable with respect to the Collateral, or any part thereof, but shall be liable only to account to Debtor any amount Secured Party or any Bank may actually collect or receive thereon and for acts constituting gross negligence or willful misconduct. Secured Party's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under the UCC or otherwise, shall be to deal with it in the same manner as Secured Party deals with similar property for its own account. Neither Secured Party, nor any Bank nor any of their directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any D-14 103 Collateral upon the request of Debtor or otherwise other than acts constituting gross negligence or willful misconduct. 11. Waiver of Certain Rights. To the full extent that it may lawfully so agree, Debtor agrees that it will not at any time plead, claim or take the benefit of any appraisement, valuation, stay, extension, moratorium or redemption law nor or hereafter in force in order to prevent or delay the enforcement of this Agreement, or the absolute sale of all or any part of the Collateral or the possession thereof by any purchaser at any sale hereunder, and Debtor hereby waives the benefit of all such laws to the extent it lawfully may. 12. Powers Coupled with an Interest. All authorizations and agencies herein contained with respect to the Collateral are irrevocable and powers coupled with an interest. 13. Performance at Debtor's Expense. The cost and expense of performing or complying with any and all of the Obligations shall be borne solely by Debtor, subject to any specific limitations thereon provided for in the Credit Agreement, and no portion of such cost and expense shall be, in any way and to any extent, credited against any installment on or portion of the Obligations. 14. Survival. Each and all of the Obligations and each and all of Debtor's representations and warranties hereunder shall survive the execution and delivery of this Agreement, and shall continue in full force and effect until the Obligations shall have been paid in full. 15. Severability. If any provision of this Agreement is held to be illegal, invalid, or unenforceable under present or future laws effective during the term hereof, such provision shall be fully severable, this Agreement shall be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part thereof, and the remaining provisions thereof shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance therefrom so as to achieve the original intent of Debtor and Secured Party. Furthermore, in lieu of such illegal, invalid, or unenforceable provision there shall be added automatically as part of this Agreement a provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible and be legal, valid and enforceable. 16. Paragraph Headings. The paragraph headings used in this Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof. 17. Cumulative Remedies. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law or in any of the other Loan Papers. 18. Successors and Assigns. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto, the Banks parties to the Credit Agreement and each such Persons' respective successors and assigns; except, that Debtor may not assign or otherwise transfer any of its rights under this Agreement. D-15 104 19. Limitation on Interest. Regardless of any provision contained in this Agreement or in the other Loan Papers, no Bank shall be entitled to receive, collect, or apply, as interest on the Loans, any amount in excess of the Maximum Lawful Rate, and in the event any Bank ever receives, collects or applies as interest any such excess, such amount which would be deemed excessive interest shall be deemed a partial prepayment of principal and treated hereunder as such; and if the Loan is paid in full, any remaining excess shall promptly be paid to Debtor. In determining whether or not the interest paid or payable under any specific contingency exceeds the Maximum Lawful Rate, Debtor, Secured Party and each Bank shall, to the extent permitted under applicable law, (a) characterize any nonprincipal payment as an expense, fee or premium rather than as interest, (b) exclude voluntary prepayments and the effects thereof and (c) amortize, prorate, allocate and spread, in equal parts, the total amount of the interest throughout the entire contemplated term of the Notes, so that the interest rate is the Maximum Lawful Rate throughout the entire term of the Notes; provided, however, that if the unpaid principal balance thereof is paid and performed in full prior to the end of the full contemplated term thereof, and if the interest received for the actual period of existence thereof exceeds the Maximum Lawful Rate, the Banks shall refund to Debtor the amount of such excess and, in such event, neither Secured Party nor any Bank shall be subject to any penalties provided by any laws for contracting for, charging, taking, reserving or receiving interest in excess of the Maximum Lawful Rate. 20. GOVERNING LAW. THIS AGREEMENT, THE NOTES, AND THE OTHER LOAN PAPERS HAVE BEEN EXECUTED AND DELIVERED IN THE STATE OF TEXAS AND SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS AND THE LAWS OF THE UNITED STATES OF AMERICA, EXCEPT TO THE EXTENT THAT THE LAWS OF A STATE IN WHICH COLLATERAL IS LOCATED NECESSARILY GOVERNS (A) THE PERFECTION AND PRIORITY OF THE LIEN AND SECURITY INTEREST CREATED HEREBY WITH RESPECT TO SUCH COLLATERAL, AND (B) THE EXERCISE OF ANY REMEDIES (INCLUDING THE FORECLOSURE OF SUCH LIEN AND SECURITY INTEREST) SUCH WITH RESPECT TO SUCH COLLATERAL. 21.

Multiple Counterparts. This Agreement may be executed in a number of identical counterparts, each of which for all purposes is to be deemed an original, and all of which constitute collectively, one Agreement; but in making proof of this Agreement, it shall not be necessary to produce or account for more than one such counterpart. It is not necessary that each party hereto D-16 105 execute the same counterpart so long as identical counterparts are executed by each such party hereto. 23. No Waiver. No course of dealing between any Bank, Secured Party and Debtor, nor any failure to exercise, nor any delay in exercising on the part of Secured Party of any right hereunder or under the Loan Papers shall operate as a waiver hereof or thereof; nor shall any single or partial exercise of any right hereunder or thereunder preclude any other or further exercise thereof or the exercise of any other right. 24. Amendments and Modifications. This Agreement shall be modified or amended only in a written document, signed by Secured Party and Debtor. 25. FINAL AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN PAPERS COLLECTIVELY REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

Exempt Property. Notwithstanding anything to the contrary contained herein, the rights and interests of Subordinate Lender in and to the Exempt Property are not subordinate to the Senior Guaranty Obligations pursuant to this Agreement, and nothing contained herein shall limit or impair the right of Subordinate Lender to enforce the Pledge Agreement or receive, retain and apply the Exempt Property to the payment of the E-5 114 Subordinate Obligations notwithstanding that the Senior Guaranty Obligations or the Credit Agreement Obligations have not been paid or performed in full. 11. Parties in Interest.

Modification and Amendments to Subordinate Obligations. Senior Lender may, without notice to Subordinate Lender, at any time, in its sole discretion, renew, extend, increase, amend, restructure, waive, compromise or otherwise change the terms of the Credit Agreement Obligations and the Credit Agreement Loan Documents and release any obligor on or collateral for the Credit Agreement Obligations without in any way altering or affecting any of the rights of Administrative Agent, or any Senior Lender under this Agreement. 16.
