(a) Borrower shall ------------------------------------- give Agent notice (a "Request for Letter of Credit") prior to 12:00 noon ---------------------------- (Dallas, Texas time) at least three (3) Domestic Business Days before the date Borrower requests that a Letter of Credit be issued. Each Request for Letter of Credit shall be substantially in the form of Exhibit B attached hereto and shall --------- be accompanied by the executed, complete letter of credit application and agreement referenced in Section 2.1(b). -------------- (b) Upon receipt of a Request for Letter of Credit, Agent shall promptly notify each Bank of the contents thereof and of the material provisions of the related letter of credit application and agreement. Agent shall provide a copy of the Request for Letter of Credit and the original counterpart of the letter of credit application and agreement to the proposed Issuer. (c) Provided that the proposed Issuer agrees to issue the requested Letter of Credit, and provided further that Agent has not determined that a condition to such issuance referred to in Section 6.2 has not been satisfied, not later ----------- than 12:00 noon (Dallas, Texas time) on the date Borrower requests that such Letter of Credit be issued, Issuer shall issue such Letter of Credit and deliver the same to the beneficiary -20- thereof and shall promptly thereafter deliver the notice to each other Bank referenced in Section 2.1(b) with respect to such Letter of Credit. -------------- SECTION 2.4. Notes. Each Bank's Commitment Percentage of the Loan shall ----- be evidenced by a single Note payable to the order of such Bank in an amount equal to such Bank's Commitment. SECTION 2.5. Refunding of Eurodollar Advances. Upon the expiration of -------------------------------- each Interest Period, each Eurodollar Advance subject to such Interest Period shall, subject to Sections 2.2 and 6.2, be refinanced pursuant to a Refunding ------------ --- Borrowing; provided, that, no Refunding Borrowing shall be made with respect to -------- ---- any Advance upon the expiration of the Interest Period applicable thereto which is required to be repaid on such date pursuant to Section 3.3. The procedure ----------- contemplated by this Section 2.5 for refinancing Advances on the expiration of ----------- the Interest Period applicable thereto with Refunding Borrowings is solely for the purpose of determining the interest rate applicable to Advances hereunder, and no repayment or new advance of funds will be deemed to occur as a result of the expiration of an Interest Period and the refinancing of the Advances subject thereto with a Refunding Borrowing. SECTION 2.6. Interest Rates. (a) Subject to Section 4.4, each Base Rate -------------- ----------- Advance shall bear interest on the outstanding principal balance thereof at a rate per annum equal to the sum of the Applicable Margin plus the Base Rate in effect from day to day, each change in the Base Rate to be effective without notice to Borrower on the effective date of each such change; provided that, in -------- ---- no event shall the rate charged hereunder or under the Notes exceed the Maximum Lawful Rate. Interest on each Base Rate Advance shall be payable each March 31, June 30, September 30 and December 31 and on the Termination Date. (b) Subject to Section 4.4, each Eurodollar Advance shall bear ----------- interest on the outstanding principal amount thereof for the Interest Period applicable thereto, at a rate per annum equal to the sum of the Applicable Margin plus 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 each Eurodollar Advance having 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. Interest on each Eurodollar Advance having an Interest Period of six (6) months shall be payable on the last day of the Interest Period applicable thereto and on each June 30, September 30, December 31 and March 31 during such Interest Period. (c) Agent shall determine each interest rate applicable to the Loan (or any portion thereof) in accordance with the terms hereof. Agent shall promptly notify Borrower and Banks by telex or cable or telecopy of each rate of interest so determined, and its determination thereof shall be conclusive in the absence of manifest error. (d) 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 reduce the rate of interest on the Loan (or any portion thereof) 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 -21- extent such payment would not result in a violation of a Law, Borrower shall be obligated to pay to the holder of such Note an amount equal to the difference between (i) the lesser of (a) the amount of interest which would have accrued if the Contract Rate had at all times been in effect, and (b) 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. SECTION 2.7. Mandatory Termination of Commitments. The Commitments shall ------------------------------------ terminate on the Termination Date, at which time the Loan (together with all accrued interest thereon) shall be due and payable in full. SECTION 2.8. Voluntary Reduction of Commitments. Borrower may, by ----------------------------------- notice to Agent one (1) Domestic Business Day 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 $1,000,000 or any larger multiple of $100,000. 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 Loan (together with accrued interest thereon) in an amount sufficient to cause the principal balance of the 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 2.9. Commitment Fee. On the Termination Date and on the last day -------------- of each June, September, December and March prior to the Termination Date, commencing on March 31, 1998, Borrower shall pay to Agent for the ratable benefit of each Bank, a commitment fee equal to the Commitment Fee Percentage in effect from day to day (computed on the basis of actual days elapsed and as if each calendar year consisted of 360 days) on the average daily Unused Availability for the calendar quarter ending on such date. SECTION 2.10. Agency Fee. Borrower shall pay to Agent such fees and ---------- other amounts as Borrower shall be required to pay to Agent from time to time pursuant to any separate agreement between Borrower and Agent. Such fees and other amounts shall be retained by Agent, and no Bank (other than Agent) shall have any interest therein. ARTICLE III BORROWING BASE SECTION 3.1. Reserve Report; Proposed Borrowing Base. As soon as --------------------------------------- available and in any event by February 20 and August 20 of each year, Borrower shall deliver to each Bank a Reserve Report prepared as of the immediately preceding January 1 and July 1, respectively. Simultaneously with each delivery of such Reserve Report, Borrower shall notify each Bank of the Borrowing Base requested by Borrower to become effective on the next Determination Date. SECTION 3.2. Determination of Borrowing Base. Based in part on the ------------------------------- Reserve Reports delivered pursuant to Section 3.1, Banks shall determine the ----------- Borrowing Base to become effective on the next succeeding Determination Date in accordance with the procedure set forth in Section 3.5 hereof; provided, -------- -22- that, in no event shall the Borrowing Base (a) exceed the Borrowing Base - ---- requested by Borrower pursuant to Section 3.1, or (b) exceed the Maximum ----------- Borrowing Base at any time on or after the Conversion Date. Subject to the foregoing and to Banks' consistent application of their respective standards for similar credits (which may vary from Bank to Bank), the Borrowing Base shall be determined by Banks in their sole discretion, but in accordance with the procedures set forth in Section 3.5 hereof. Without limiting the discretion of ----------- Banks in determining the Borrowing Base, Borrower acknowledges and agrees that, subject as aforesaid, Banks (i) may make such assumptions regarding appropriate existing and projected pricing for hydrocarbons as they deem appropriate in their sole discretion, (ii) may make such assumptions regarding projected rates and quantities of future production of hydrocarbons from the Mineral Interests owned by Borrower and its Subsidiaries as they deem appropriate in their sole discretion, (iii) may consider the projected cash requirements of Borrower and its Subsidiaries, (iv) are not required to consider any asset other than Mineral Interests, (v) will give no consideration to any asset owned by a Person other than Borrower and Subsidiary Guarantors, and (vi) may make such other assumptions, considerations and exclusions as Banks deem appropriate in the exercise of their sole discretion. Agent shall notify Borrower of the Borrowing Base to become effective on each Determination Date no later than 2:00 p.m., Dallas, Texas time on such Determination Date. SECTION 3.3. Borrowing Base Deficiency. (a) If, on any Determination ------------------------- Date, a Borrowing Base Deficiency exists as a result of a redetermination of the Borrowing Base on such date, Borrower shall either (i) on or before the thirtieth (30th) day following such Determination Date, make a prepayment of principal on the Loan in an amount equal to the amount of such Borrowing Base Deficiency, or (ii) make six (6) equal consecutive monthly prepayments of principal on the Loan, each of which shall be in the amount of one sixth (1/6th) of such Borrowing Base Deficiency. The first of such six (6) prepayments shall be due on the thirtieth (30th) day following such Determination Date, and each subsequent prepayment shall be due on the same day of each month thereafter (or if there is no corresponding day of any subsequent month, then on the last day of such month). (b) If a Borrowing Base Deficiency occurs or an existing Borrowing Base Deficiency increases as a result of any quarterly reduction of the Maximum Borrowing Base, then, on the date of such quarterly reduction in the Maximum Borrowing Base, Borrower shall make a prepayment of principal on the Loan in the amount of such Borrowing Base Deficiency. For purposes of this Section ------- 3.3(b) and Section 3.3(a) above, if (i) a Determination Date is also the date of - ------ -------------- any quarterly reduction in the Maximum Borrowing Base, and (ii) the Borrowing Base in effect immediately prior to such Determination Date is higher than the amount of the Maximum Borrowing Base as reduced on such Determination Date, then the reduction in the Borrowing Base which becomes effective on such Determination Date will be deemed to have resulted from the reduction in the Maximum Borrowing Base to the extent of the difference between the Borrowing Base in effect immediately prior to such Determination Date and the Maximum Borrowing Base in effect as reduced on such Determination Date. SECTION 3.4. Initial Borrowing Base. Notwithstanding anything to the ---------------------- contrary contained herein, the Borrowing Base shall be $80,000,000 for the period commencing on the date hereof and continuing until the first Determination Date after the Closing Date. SECTION 3.5. Procedure for Determining Borrowing Base. Following ---------------------------------------- delivery of each Reserve Report required to be delivered to Banks pursuant to Section 3.1, Banks shall attempt to mutually agree among themselves on the - ----------- Borrowing Base to become effective on the next Determination Date. In the -23- event (a) such Borrowing Base represents an increase from the Borrowing Base in effect prior to such Determination Date, such Borrowing Base shall be approved by all Banks, and (b) such Borrowing Base represents a decrease in the Borrowing Base in effect prior to such Determination Date, or a reaffirmation of such prior Borrowing Base, such Borrowing Base shall be approved by Banks holding seventy-five percent (75%) of the Total Commitment (whenever such decision is reached). ARTICLE IV GENERAL PROVISIONS SECTION 4.1. Delivery and Endorsement of Notes. Simultaneously with the --------------------------------- execution of this Agreement, Agent shall deliver to each Bank the Notes payable to such Bank referenced in Section 6.1(a). Each Bank may endorse (and prior to -------------- any transfer of its Note shall endorse) on the schedules forming a part thereof appropriate notations to evidence the date and amount of each Advance 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 any Note held by it shall not affect the liability of the maker of such Note 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 Notes and to attach to and make a part of any Note a continuation of any such schedule as required. SECTION 4.2. General Provisions as to Payments. (a) Each payment of --------------------------------- principal of, and interest on, the 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 immediately available funds to Agent at its address referred to in Section 13.1. ------------ (b) Prior to the occurrence of an Event of Default, all principal payments received by Banks shall be applied, first, to Advances with Interest Periods ending on the date of such payment, then to Base Rate Advances, then to Eurodollar Advances (as Borrower shall elect but in the absence of such election, in such order as Agent shall elect), next maturing until such principal payment is fully applied, with such adjustments in such order of payment as Agent shall specify in order that each Bank receives its ratable share of each such payment. (c) After the occurrence of an Event of Default, all amounts collected or received by Agent or any Bank shall be applied first to the payment of all proper costs incurred by Agent in connection with the collection thereof (including reasonable expenses and disbursements of Agent), second to the payment of all proper costs incurred by Banks in connection with the collection thereof (including reasonable expenses and disbursements of Banks, but only to the extent Borrower is obligated therefor under the Loan Papers), third to the reimbursement of any advances made by Banks to effect performance of any unperformed covenants of Borrower under any of the Loan Papers, fourth to the payment of any unpaid agency fees required pursuant to Section 2.10, fifth to ------------ the payment of any unpaid interest on the Loan or any unpaid fees required pursuant to Sections 2.1(b) and 2.9, and sixth, to payment of the Loan in the --------------- --- manner provided in Section 4.2(b). -------------- SECTION 4.3. Computation of Interest. Interest payable on the Loan ----------------------- hereunder shall be computed based on the number of actual days elapsed assuming that each calendar year consisted of 360 -24- days. The annual rates of interest to which rates determined assuming a calendar year of 360 days are equivalent, are the rates so determined multiplied by the actual number of days in a period of one (1) year commencing on the first day of the period for which such interest is payable and divided by 360. SECTION 4.4. Overdue Principal and Interest. Any overdue principal of ------------------------------ and, to the extent permitted by Law, overdue interest on the Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the sum of three percent (3%) plus the Base Rate. SECTION 4.5. Limitation on Number of Eurodollar Advances. Unless ------------------------------------------- otherwise agreed by Agent with the consent of Majority Banks, there may be no more than six (6) Eurodollar Borrowings outstanding at any time in favor of each Bank. ARTICLE V CHANGE IN CIRCUMSTANCES SECTION 5.1. 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 adopted after the date hereof (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 Advances, its Note, or its obligation to make Eurodollar Advances, 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 Advances (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; 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 Advances or to reduce any sum -25- received or receivable by such Bank (or its Applicable Lending Office) under this Agreement or its Note with respect to any Eurodollar Advances, 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 5.1(a), Borrower may, by notice to -------------- such Bank (with a copy to Agent), suspend the obligation of such Bank to make or Continue Advances of the Type with respect to which such compensation is requested, or to Convert Advances of any other Type into Advances of such Type, until the event or condition giving rise to such request ceases to be in effect (in which case the provisions of Section 5.4 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 adopted after the date hereof 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 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 5.1 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 5.1 shall furnish to Borrower and 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 5.2. Limitation on Types of Advances. If on or prior to the ------------------------------- first day of any Interest Period for any Eurodollar Advance: (a) 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 (b) Majority Banks determine (which determination shall be conclusive) and notify Agent that the Adjusted Eurodollar Rate will not adequately and fairly reflect the cost to Banks of funding Eurodollar Advances for such Interest Period; then Agent shall give Borrower prompt notice thereof specifying the relevant Type of Advances and the relevant amounts or periods, and so long as such condition remains in effect, Banks shall be under no obligation to make additional Advances of such Type, Continue Advances of such Type, or to Convert Advances of any other Type into Advances of such Type and Borrower shall, on the last day(s) of the then -26- current Interest Period(s) for the outstanding Advances of the affected Type, either prepay such Advances or Convert such Advances into another Type of Advance in accordance with the terms of this Agreement. SECTION 5.3. 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 Advances hereunder, then such Bank shall promptly notify Borrower thereof and such Bank's obligation to make or Continue Eurodollar Advances and to Convert other Types of Advances into Eurodollar Advances shall be suspended until such time as such Bank may again make, maintain, and fund Eurodollar Advances (in which case the provisions of Section 5.4 shall be applicable). - ----------- SECTION 5.4. Treatment of Advances. If the obligation of any Bank to --------------------- make a Eurodollar Advance or to Continue, or to Convert Advances of any other Type into, Eurodollar Advances shall be suspended pursuant to Section 5.1 or 5.3 ----------- --- hereof, such Bank's Eurodollar Advances shall be automatically Converted into Base Rate Advances on the last day(s) of the then current Interest Period(s) for Eurodollar Advances (or, in the case of a Conversion required by Section 5.3 ----------- hereof, on such earlier date as such Bank may specify to Borrower with a copy to Agent) and, unless and until such Bank gives notice as provided below that the circumstances specified in Section 5.1 or 5.3 hereof that gave rise to such ----------- --- Conversion no longer exist: (a) to the extent that such Bank's Eurodollar Advances have been so Converted, all payments and prepayments of principal that would otherwise be applied to such Bank's Eurodollar Advances shall be applied instead to its Base Rate Advances; and (b) all Advances that would otherwise be made or Continued by such Bank as Eurodollar Advances shall be made or Continued instead as Base Rate Advances, and all Advances of such Bank that would otherwise be Converted into Eurodollar Advances shall be Converted instead into (or shall remain as) Base Rate Advances. If such Bank gives notice to Borrower (with a copy to Agent) that the circumstances specified in Section 5.1 or 5.3 hereof that gave rise to the ----------- --- Conversion of such Bank's Eurodollar Advances pursuant to this Section 5.4 no ----------- longer exist (which such Bank agrees to do promptly upon such circumstances ceasing to exist) at a time when Eurodollar Advances made by other Banks are outstanding, such Bank's Base Rate Advances shall be automatically Converted, on the first day(s) of the next succeeding Interest Period(s) for such outstanding Eurodollar Advances to the extent necessary so that, after giving effect thereto, all Advances held by Banks holding Eurodollar Advances are held pro rata (as to principal amounts, Types, and Interest Periods) in accordance with their respective Commitments. SECTION 5.5. 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 Advance for any reason (including, without limitation, the acceleration of the Loan pursuant to Section 11.1) on a date other than the last day of the Interest Period for such - ------------ Advance; or -27- (b) any failure by Borrower for any reason (including, without limitation, the failure of any condition precedent specified in Article VI to be satisfied) ---------- to borrow, Convert, Continue, or prepay a Eurodollar Advance 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 5.6 Taxes. (a) Any and all payments by Borrower to or for the ----- account of any Bank or 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 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 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 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 5.6) such Bank or 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 Agent, at its address set forth on the signature pages hereto, evidence of 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"). - ----- (c) Borrower agrees to indemnify each Bank and 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 ------- 5.6) paid by such Bank or 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 the signature pages 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 Agent (but only so long as such Bank remains lawfully able to do so), shall provide Borrower and 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. -28- (e) For any period with respect to which a Bank has failed to provide Borrower and Agent with the appropriate form pursuant to Section 5.6(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 5.6(a) or -------------- 5.6(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 5.6, 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. (g) Within thirty (30) days after the date of any payment of Taxes, Borrower shall furnish to Agent evidence of such payment. (h) Without prejudice to the survival of any other agreement of Borrower hereunder, the agreements and obligations of Borrower contained in this Section ------- 5.6 shall survive the termination of the Commitments and the payment in full of - --- the Notes. SECTION 5.7. Discretion of Banks as to Manner of Funding. ------------------------------------------- Notwithstanding any provisions of this Agreement to the contrary, each Bank shall be entitled to fund and maintain its funding of all or any part of its Advances in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if such Bank had actually funded and maintained each Eurodollar Advance during the Interest Period for such Eurodollar Advance through the purchase of deposits in the London interbank market having a maturity corresponding to the last day of such Interest Period and bearing an interest rate equal to the Eurodollar Rate for such Interest Period. ARTICLE VI CONDITIONS PRECEDENT SECTION 6.1. Conditions to Initial Borrowing and Participation in Letter ----------------------------------------------------------- of Credit Exposure.

(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 13.4 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 Advances owing to it, or interest thereon, or receive any collateral in respect thereof (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 Advances 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 Advances 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 Bank; 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 13.4 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 13.5. 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 Majority Banks (and, if Article XII or the rights or duties of Agent are affected thereby, by 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 Advance 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 Advance 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 13.5 or any other provision of this ------------ Agreement, or (v) release any guarantor (including, without limitation, any Subsidiary Guarantor) of the Obligations or all or substantially all of the collateral securing the Obligations. -51- SECTION 13.6. Survival. All representations, warranties and covenants -------- made by Borrower or any Subsidiary of Borrower 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 Loan (or any part thereof), and the issuance of Letters of Credit regardless of any investigation made by or on behalf of Banks. The provisions of Section 13.3 hereof shall survive payment ------------ in full of the Obligations and the termination of this Agreement. SECTION 13.7. 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 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 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, 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 appropriate 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 13.8. 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 13.9. 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 Loan.

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 Agent certification as to exemption from deduction or withholding of Taxes in accordance with Section 5.6(d). -------------- (b) Agent shall maintain at its address set forth on the signature pages 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 Loan owing to, each Bank from time to time (the "Register").

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), subject, however, to the provisions of Section 13.17 hereof. ------------- SECTION 13.11.
