The obligations of the Borrower and each Bank under this Agreement and the Letter of Credit Applications to reimburse an Issuing Bank for draws under Letters of Credit issued by such Issuing Bank and to make other payments due in respect of Letters of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement and the Letter of Credit Applications under all circumstances, including: (i) any lack of validity or enforceability of any Letter of Credit Document; (ii) any amendment, waiver, or consent to departure from any Letter of Credit Document; (iii) the existence of any claim, set-off, defense, or other right which the Borrower or any Bank may have at any time against any beneficiary or transferee of any Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), such Issuing Bank, or any other person or entity, whether in connection with the transactions contemplated in this Agreement or any unrelated transaction; (iv) any statement or any other document presented under such Letter of Credit proving to be forged, fraudulent, invalid, or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or (v) payment by such Issuing Bank under any Letter of Credit against presentation of a draft or certificate which does not comply with the terms of such Letter of Credit; provided, however, that nothing contained in this paragraph (d) shall be deemed to constitute a waiver of any remedies of the Borrower or any Bank in connection with the Letters of Credit or the Borrower's or such Bank's rights under paragraph (e) below. (f) LIABILITY OF ISSUING BANK. No Issuing Bank shall be liable or responsible for: (i) the use which may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith; (ii) the validity, sufficiency, or genuineness of documents related to Letters of Credit, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent, or forged; (iii) payment by such Issuing Bank against presentation of documents which do not strictly comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to the relevant Letter of Credit; or (iv) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit (INCLUDING SUCH ISSUING BANK'S OWN NEGLIGENCE); except that such Issuing Bank shall be liable to the Borrower or any Bank to the extent of any direct, as opposed to consequential, damages suffered by the Borrower or such Bank which the Borrower or such Bank proves were caused by (A) such Issuing Bank's gross negligence or willful misconduct in determining whether documents presented under a Letter of -22- Credit comply with the terms of such Letter of Credit, (B) such Issuing Bank's willful failure to make or delay in making lawful payment under any Letter of Credit after the presentation to it of documentation strictly complying with the terms and conditions of such Letter of Credit, or (C) such Issuing Bank's negligence in the handling of money. (g) LETTER OF CREDIT COLLATERAL ACCOUNT. (i) If the Borrower is required to deposit funds in the Letter of Credit Collateral Account pursuant to Sections 2.1(d)(ii), 2.3(d) or 6.4, then the Borrower and the Agent shall establish the Letter of Credit Collateral Account and the Borrower shall execute any documents and agreements, including the Agent's standard form assignment of deposit accounts, that the Agent requests in connection therewith to establish the Letter of Credit Collateral Account and grant the Agent a first priority security interest in such account and the funds therein. The Borrower hereby pledges to the Agent and grants the Agent a security interest in the Letter of Credit Collateral Account, whenever established, all funds held in the Letter of Credit Collateral Account from time to time, and all proceeds thereof as security for the payment of the Obligations. (ii) So long as no Event of Default exists, (A) the Agent shall apply the funds held in the Letter of Credit Collateral Account only to the reimbursement of any reimbursement obligations and other obligations under Letter of Credit Documents, (B) the Agent shall release to the Borrower at the Borrower's written request funds held in the Letter of Credit Collateral Account in an amount up to but not exceeding the excess, if any (immediately prior to the release of any such funds), of the total amount of funds held in the Letter of Credit Collateral Account over the Letter of Credit Exposure, and (C) the Agent shall, at the unanimous written direction of the Banks in their sole discretion, at any time release to the Borrower any funds held in the Letter of Credit Collateral Account. During the existence of any Default or Event of Default, the Agent may apply any funds held in the Letter of Credit Collateral Account to any Credit Obligations in any order determined by the Agent, regardless of any Letter of Credit Exposure which may remain outstanding. (iii) Funds held in the Letter of Credit Collateral Account shall be invested in money market funds of the Agent or in another investment if mutually agreed upon by the Borrower and the Agent, but the Agent shall have no other obligation to make any other investment of the funds therein. The Agent shall exercise reasonable care in the custody and preservation of any funds held in the Letter of Credit Collateral Account and shall be deemed to have exercised such care if such funds are accorded treatment substantially equivalent to that which the Agent accords its own property, it being understood that the Agent shall not have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any such funds. (h) EXISTING LETTERS OF CREDIT. Upon the date of the execution of this Agreement, the Issuing Bank for each Existing Letter of Credit shall be deemed to have sold to each other Bank and each other Bank shall be deemed to have purchased from such Issuing Bank a ratable participation in each Existing Letter of Credit, which shall thereafter be treated as a Letters of Credit under this Agreement for all purposes. Each Issuing Bank for each Existing Letter of -23- Credit shall arrange with the Agent and the Banks to prorate and ratably distribute to the Banks the fees, if any, previously paid in advance to such Issuing Bank with respect to such Existing Letters of Credit. 2.4 FEES. (a) COMMITMENT FEES. The Borrower shall pay to the Agent for the ratable benefit of the Banks a commitment fee in an amount equal to the product of (i) the Applicable Margin for commitment fees calculated for the preceding quarter multiplied by (ii) the average daily amount by which (x) the aggregate amount of the Revolving Credit Commitments exceeds (y) the outstanding principal amount of the Revolving Credit Loan plus the Letter of Credit Exposure. The commitment fee shall be due and payable quarterly in arrears on the last day of each calendar quarter commencing December 31, 2001 and on the Revolving Credit Maturity Date. (b) FEES FOR LETTERS OF CREDIT. The Borrower agrees to pay (i) to the Agent for the pro rata benefit of the Banks, a fee for each Letter of Credit equal to the Applicable Margin for Letters of Credit on the face amount of such Letter of Credit, with a minimum fee of $500, and (ii) to the Issuing Bank, a fee for each Letter of Credit of 0.125% per annum of the face amount of such Letter of Credit. Each such fee shall be calculated on a per annum basis in accordance with Section 2.10(g) and shall be based on the maximum amount available to be drawn from time to time under such Letter of Credit from the date of issuance of the Letter of Credit until its Expiration Date and shall be payable quarterly in arrears on the last day of each calendar quarter. (c) AGENT FEE LETTER. The Borrower shall pay to the parties specified therein the fees and other amounts payable under Agent Fee Letter and the letter dated September 27, 2001 between the Agent and the Borrower. 2.5 INTEREST. (a) ELECTION OF INTEREST RATE BASIS. The Borrower may select the interest rate basis for each Borrowing in accordance with the terms of this Section 2.5(a): (i) Under the Borrowing Request provided to the Agent in connection with the making of each Borrowing under the Revolving Credit Loan, the Borrower shall select the amount and the Type of the Tranches, and for each LIBOR Tranche selected, any permitted Interest Period for each such LIBOR Tranche, which will comprise such Borrowing, provided that (A) at no time shall there be more than eight separate LIBOR Tranches outstanding under the Revolving Credit Loan and (B) each Tranche must be in a principal amount equal to or greater than the Minimum Tranche Amount and be made in multiples of the Minimum Tranche Multiple. Such interest rate elections must be provided to the Agent in writing or by telecopy not later than 11:00 a.m. (Dallas, Texas time) (A) on the third Business Day before the date of any proposed Borrowing comprised of a LIBOR Tranche, or (B) on the same day of any proposed Borrowing comprised solely of a Prime Rate Tranche. The Agent shall promptly forward copies of such interest rate elections to the Banks. In the case of any Borrowing comprised of a LIBOR Tranche, upon determination by the Agent, the Agent shall promptly notify the Borrower and the Banks of the applicable interest rate for such Tranche. -24- (ii) With respect to any Tranche under the Revolving Credit Loan, the Borrower may continue or convert any portion of any LIBOR Tranche or Prime Rate Tranche to form new LIBOR Tranches or Prime Rate Tranches under the Revolving Credit Loan in accordance with this paragraph. Each such continuation or conversion shall be made pursuant to a Continuation/Conversion Request given by the Borrower to the Agent in writing or by telecopy not later than 11:00 a.m. (Dallas, Texas time) on the third Business Day before the date of the proposed continuation or conversion. Each Continuation/Conversion Request shall be fully completed and shall specify the information required therein, and shall be irrevocable and binding on the Borrower. The Agent shall promptly forward notice of the continuation or conversion to the Banks. In the case of any continuation or conversion into LIBOR Tranches, upon determination by the Agent, the Agent shall notify the Borrower and the Banks of the applicable interest rate. Continuations and conversions of Tranches shall be made in integral multiples of the Minimum Tranche Multiple. No continuation or conversion shall be permitted if such continuation or conversion would cause the aggregate outstanding principal amount of any LIBOR Tranche which would remain outstanding or the aggregate outstanding principal amount of all Prime Rate Tranches which would remain outstanding to be less than the Minimum Tranche Amount. At no time shall there be more than eight separate LIBOR Tranches outstanding under the Revolving Credit Loan. Any conversion of an existing LIBOR Tranche is subject to Section 2.5. Subject to the satisfaction of all applicable conditions precedent, the Agent and the Banks shall before close of business on the date requested by the Borrower for the continuation or conversion, make such continuation or conversion. (iii) At the end of the Interest Period for any LIBOR Tranche, if the Borrower has not continued or converted such LIBOR Tranche into new Tranches as provided for in paragraph (ii) above, the Borrower shall be deemed to have continued such LIBOR Tranche as a Prime Rate Tranche. Each Prime Rate Tranche shall continue as a Prime Rate Tranche unless the Borrower converts such Prime Rate Tranche as provided for in paragraph (ii) above. (b) LIBOR TRANCHES. Each LIBOR Tranche shall bear interest during its Interest Period at a per annum interest rate equal to the lesser of (i) the Highest Lawful Rate or (ii) the sum of the LIBOR for such Tranche plus the Applicable Margin for LIBOR Tranches in effect from time to time. The Borrower shall pay to the Agent for the ratable benefit of the Banks all accrued but unpaid interest on each LIBOR Tranche on the last day of the applicable Interest Period for such LIBOR Tranche (and with respect to LIBOR Tranches with Interest Periods of greater than three months, on the date which is three months after the first date of the Interest Period for such LIBOR Tranche), when required upon prepayment as specified elsewhere in this Agreement, on any date when any portion of any LIBOR Tranche is prepaid (but only to the extent of the portion of any such LIBOR Tranche is prepaid), and on the Revolving Credit Maturity Date. (c) PRIME RATE TRANCHES. Each Prime Rate Tranche shall bear interest at a per annum interest rate equal to the lesser of (i) the Highest Lawful Rate or (ii) the Adjusted Prime Rate in effect from time to time plus the Applicable Margin for Prime Rate Tranches in effect from time to time. The Borrower shall pay to the Agent for the ratable benefit of the Banks all accrued but -25- unpaid interest on outstanding Prime Rate Tranches on the last day of each calendar quarter, when required upon prepayment as specified elsewhere in this Agreement, on any date all Prime Rate Tranches are prepaid in full, and on the Revolving Credit Maturity Date. (d) USURY PROTECTION. (i) Nothing contained in this Agreement or the Notes shall require the Borrower to pay interest at a rate exceeding the Highest Lawful Rate. Each provision in the Credit Documents and any other agreement executed in connection herewith is expressly limited so that in no event whatsoever shall the amount paid thereunder, or otherwise paid, by the Borrower for the use, forbearance or detention of the money to be loaned under this Agreement, exceed that amount of money which would cause the effective rate of interest thereon to exceed the Highest Lawful Rate, and all amounts payable under the Credit Documents or any other agreement executed in connection herewith, or otherwise payable in connection therewith, shall be subject to reduction so that such amounts paid or payable for the use, forbearance or detention of money to be loaned under this Agreement shall not exceed that amount of money which would cause the effective rate of interest thereon to exceed the Highest Lawful Rate. (ii) If the amount of interest payable for the account of any Bank on any interest payment date in respect of the immediately preceding interest computation period, computed pursuant to this Section 2.5, would exceed the maximum amount permitted by applicable law to be charged by such Bank, the amount of interest payable for its account on such interest payment date shall be automatically reduced to such maximum permissible amount. (iii) If the amount of interest payable for the account of any Bank in respect of any interest computation period is reduced pursuant to clause (d)(ii) above and the amount of interest payable for its account in respect of any subsequent interest computation period, computed pursuant to this Section 2.5, would be less than the maximum amount permitted by applicable law to be charged by such Bank, then the amount of interest payable for its account in respect of such subsequent interest computation period shall be automatically increased to the maximum amount permitted by applicable law to be charged by such Bank; PROVIDED that at no time shall the aggregate amount by which interest paid for the account of any Bank has been increased pursuant to this clause (d)(iii) exceed the aggregate amount by which interest paid for its account has theretofore been reduced pursuant to clause (d)(ii) of this Section. (iv) In the event that maturity of the loans made hereunder is accelerated for any reason, or in the event of any required or permitted prepayment of such loans, then such consideration that constitutes interest payable for the account of any Bank shall never include more than the maximum amount permitted by applicable law to be charged by such Bank and excess interest, if any, payable for the account of such Bank pursuant to its Note, this Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited on the loans made hereunder by such Bank (or, to the extent in excess of such loans, refunded by such Bank to the Borrower). -26- (v) It is further agreed that, without limitation of the foregoing, all calculations of the rate of interest contracted for, charged or received for the account of any Bank under the Note held by it, under this Agreement, under any other agreement executed in connection herewith or otherwise in connection with the loans made hereunder by or the Revolving Credit Commitment of such Bank for the purpose of determining whether such rate exceeds the Highest Lawful Rate, shall be made, to the extent permitted by applicable usury law (now or hereafter enacted), by amortizing, prorating and spreading in equal parts during the period of the full stated terms of the loans evidenced by such Note all interest at any time contracted for, charged or received by such Bank in connection therewith. 2.6 BREAKAGE COSTS. If (i) any payment of principal on or any conversion of any LIBOR Tranche is made on any date other than the last day of the Interest Period for such LIBOR Tranche, whether as a result of any voluntary or mandatory prepayment, any acceleration of maturity, or any other cause, (ii) any payment of principal on any LIBOR Tranche is not made when due, or (iii) any LIBOR Tranche is not borrowed, converted, or prepaid in accordance with the respective notice thereof provided by the Borrower to the Agent, whether as a result of any failure to meet any applicable conditions precedent for borrowing, conversion, or prepayment, the permitted cancellation of any request for borrowing, conversion, or prepayment, the failure of the Borrower to provide the respective notice of borrowing, conversion, or prepayment, or any other cause not specified above which is created by the Borrower, then the Borrower shall pay to each Bank upon demand any amounts required to compensate such Bank for any losses, costs, or expenses, including lost profits and administrative expenses, which are reasonably allocable to such action, including losses, costs, and expenses related to the liquidation or redeployment of funds acquired or designated by such Bank to fund or maintain such Bank's ratable share of such LIBOR Tranche or related to the reacquisition or redesignation of funds by such Bank to fund or maintain such Bank's ratable share of such LIBOR Tranche following any liquidation or redeployment of such funds caused by such action. A certificate as to the amount of such loss, cost, or expense detailing the calculation thereof and certifying that such Bank customarily charges such amounts to its other customers in similar circumstances submitted by such Bank to the Borrower shall be conclusive and binding for all purposes, absent manifest error. 2.7 INCREASED COSTS. (a) COST OF FUNDS. If due to either (i) any introduction of, change in, or change in the interpretation of any law or regulation after the date of this Agreement or (ii) compliance with any guideline or request applying to banks generally from any central bank or other governmental authority having appropriate jurisdiction (whether or not having the force of law) given after the date of this Agreement, there shall be any increase in the costs of any Bank allocable to (x) committing to make any Advance or obtaining funds for the making, funding, or maintaining of such Bank's ratable share of any LIBOR Tranche in the relevant interbank market or (y) committing to make Letters of Credit or issuing, funding, or maintaining Letters of Credit (including any increase in any applicable reserve requirement specified by the Federal Reserve Board, including those for emergency, marginal, supplemental, or other reserves), then the Borrower shall pay to such Bank upon demand any amounts required to compensate such Bank for such increased costs, such amounts being due and payable upon demand by such Bank. A certificate as to the cause and amount of such increased cost detailing the calculation of such cost -27- and certifying that such Bank customarily charges such amounts to its other customers in similar circumstances submitted by such Bank to the Borrower shall be conclusive and binding for all purposes, absent manifest error. Notwithstanding the foregoing, the Borrower shall not be obligated to pay any such amounts that accrued more than 90 days prior to delivery of such certificate to the Borrower. (b) CAPITAL ADEQUACY. If, due to either (i) any introduction of, change in, or change in the interpretation of any law or regulation after the date of this Agreement or (ii) compliance with any guideline or request applying to banks generally from any central bank or other governmental authority having appropriate jurisdiction (whether or not having the force of law) given after the date of this Agreement, there shall be any increase in the capital requirements of any Bank or its parent or holding company allocable to (x) committing to make Advances or making, funding, or maintaining Advances or (y) committing to make Letters of Credit or issuing, funding, or maintaining Letters of Credit, as such capital requirements are allocated by such Bank, then the Borrower shall pay to such Bank upon demand any amounts required to compensate such Bank or its parent or holding company for such increase in costs (including an amount equal to any reduction in the rate of return on assets or equity of such Bank or its parent or holding company), such amounts being due and payable upon demand by such Bank. A certificate as to the cause and amounts detailing the calculation of such amounts and certifying that such Bank customarily charges such amounts to its other customers in similar circumstances submitted by such Bank to the Borrower shall be conclusive and binding for all purposes, absent manifest error. Notwithstanding the foregoing, the Borrower shall not be obligated to pay any such amounts that accrued more than 90 days prior to delivery of such certificate to the Borrower. 2.8 ILLEGALITY. Notwithstanding any other provision in this Agreement, if it becomes unlawful for any Bank to obtain deposits or other funds for making or funding such Bank's ratable share of any LIBOR Tranche in the relevant interbank market, such Bank shall so notify the Borrower and the Agent and such Bank's commitment to create LIBOR Tranches shall be suspended until such condition has passed, all LIBOR Tranches applicable to such Bank shall be converted to Prime Rate Tranches as of the end of each applicable Interest Period or earlier if necessary, and all subsequent requests for LIBOR Tranches shall be deemed to be requests for Prime Rate Tranches with respect to such Bank. 2.9 MARKET FAILURE. Notwithstanding any other provision in this Agreement, if the Agent determines that: (a) quotations of interest rates for the relevant deposits referred to in the definition of "LIBOR" are not being provided in the relevant amounts, or maturities for purposes of determining the rate of interest referred to in the definition of "LIBOR" or (b) the relevant rates of interest referred to in the definition of "LIBOR" which are used as the basis to determine the rate of interest for LIBOR Tranches are not likely to adequately cover the cost to any Bank of making or maintaining such Bank's ratable share of any LIBOR Tranche, then if the Agent so notifies the Borrower, the commitment of the Banks to make any Borrowing comprised of LIBOR Tranches shall be suspended until such condition has passed, all LIBOR Tranches shall be converted to Prime Rate Tranches as of the end of each applicable Interest Period or earlier if necessary, and all subsequent requests for LIBOR Tranches shall be deemed to be requests for Prime Rate Tranches. -28- 2.10 ADVANCING AND PAYMENTS GENERALLY; COMPUTATIONS. (a) ADVANCING PROCEDURES. Time is of the essence in this Agreement and the Credit Documents. All advances hereunder shall be made in Dollars. Upon receipt of any Borrowing Request by the Agent, the Agent shall promptly forward notice of the Borrowing to the Banks. Subject to the satisfaction of the applicable conditions precedent, each Bank shall, before 1:00 p.m. (Dallas, Texas time) on the date of the requested Borrowing, make available from its Applicable Lending Office to the Agent at the Agent's Applicable Lending Office, in immediately available funds, such Bank's ratable share of such Borrowing. Subject to the satisfaction of all applicable conditions precedent, after receipt by the Agent of such funds, the Agent shall, by 4:00 p.m. (Dallas, Texas time) on the date requested for such Borrowing, make such Borrowing available to the Borrower in immediately available funds at any account of Borrower which is designated in writing by the Borrower to the Agent. (b) AGENT RELIANCE ON BANKS IN ADVANCING. Unless the Agent shall have received notice from a Bank before the date of any Borrowing that such Bank shall not make available to the Agent such Bank's ratable share of such Borrowing, the Agent may assume that such Bank has made its ratable share of such Borrowing available to the Agent on the date of such Borrowing in accordance with this Agreement and the Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Bank shall not have so made its ratable share of such Borrowing available to the Agent, such Bank agrees that it shall pay interest on such amount for each day from the date such amount is made available to the Borrower by the Agent until the date such amount is paid to the Agent by such Bank at the Federal Funds Rate in effect from time to time, provided that with respect to such Bank if such amount is not paid by such Bank by the end of the second day after the Agent makes such amount available to the Borrower, the interest rates specified above shall be increased by a per annum amount equal to 2.00% on the third day and shall remain at such increased rate thereafter. Interest on such amount shall be due and payable by such Bank upon demand by the Agent. If such Bank shall pay to the Agent such amount and interest as provided above, such amount so paid shall constitute such Bank's Advance as part of such Borrowing for all purposes of this Agreement even though not made on the same day as the other Advances comprising such Borrowing. In the event that such Bank has not repaid such amount by the end of the fifth day after such amount was made available to the Borrower, the Borrower agrees to repay to the Agent on demand such amount, together with interest on such amount for each day from the date such amount was made available to the Borrower until the date such amount is repaid to the Agent at the interest rate charged to the Borrower for such Borrowing under the terms of this Agreement. The failure of any Bank to make available its ratable share of any Borrowing shall not relieve any other Bank of its obligation, if any, to make available its ratable share of such Borrowing. No Bank shall be responsible for the failure of any other Bank to honor such other Bank's obligations hereunder, including any failure to make available any funds as part of any Borrowing; provided, however, that nothing herein shall prejudice any right or cause of action that the Borrower has against any Bank failing to so honor its obligations. (c) PAYMENT PROCEDURES. Time is of the essence in this Agreement and the Credit Documents. All payments hereunder shall be made in Dollars. The Borrower shall make each payment under this Agreement and under the Notes not later than 1:00 p.m. (Dallas, Texas time) on the day when due to the Agent at the Agent's Applicable Lending Office in immediately -29- available funds. All payments by the Borrower hereunder shall be made without any offset, abatement, withholding, deduction, counterclaim, or reduction. Upon receipt of payment from the Borrower of any principal, interest, or fees due to the Banks, the Agent shall promptly after receipt thereof distribute to the Banks their ratable share of such payments for the account of their respective Applicable Lending Offices. If and to the extent that the Agent shall not have so distributed to any Bank its ratable share of such payments, the Agent agrees that it shall pay interest on such amount for each day after the day when such amount is made available to the Agent by the Borrower until the date such amount is paid to such Bank by the Agent at the Federal Funds Rate in effect from time to time, provided that if such amount is not paid by the Agent by the end of the third day after the Borrower makes such amount available to the Agent, the interest rates specified above shall be increased by a per annum amount equal to 2.00% on the fourth day and shall remain at such increased rate thereafter. Interest on such amount shall be due and payable by the Agent upon demand by such Bank. Upon receipt of other amounts due solely to the Agent, such Issuing Bank, or a specific Bank, the Agent shall distribute such amounts to the appropriate party to be applied in accordance with the terms of this Agreement. (d) AGENT RELIANCE. Unless the Agent shall have received written notice from the Borrower prior to any date on which any payment is due to the Banks that the Borrower shall not make such payment in full, the Agent may assume that the Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such date an amount equal to the amount then due such Bank. If and to the extent the Borrower shall not have so made such payment in full to the Agent, each Bank shall repay to the Agent forthwith on demand such amount distributed to such Bank, together with interest thereon from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Agent, at an interest rate equal to, the Federal Funds Rate in effect from time to time, provided that with respect to such Bank, if such amount is not repaid by such Bank by the end of the second day after the date of the Agent's demand, the interest rates specified above shall be increased by a per annum amount equal to 2.00% on the third day after the date of the Agent's demand and shall remain at such increased rate thereafter. (e) SHARING OF PAYMENTS. Each Bank agrees that if it should receive any payment (whether by voluntary payment, by realization upon security, by the exercise of the right of setoff or banker's lien, by counterclaim or cross action, by the enforcement of any right under the Credit Documents, or otherwise) in respect of any obligation of the Borrower to pay principal, interest, fees, or any other obligation incurred under the Credit Documents in a proportion greater than the total amount of such principal, interest, fees, or other obligation then owed and due by the Borrower to such Bank bears to the total amount of principal, interest, fees, or other obligation then owed and due by the Borrower to all of the Banks immediately prior to such receipt, then such Bank receiving such excess payment shall purchase for cash without recourse from the other Banks an interest in the obligations of the Borrower to such Banks in such amount as shall result in a participation by all of the Banks, in proportion with the Banks' respective pro rata shares, in the aggregate unpaid amount of principal, interest, fees, or any such other obligation, as the case may be, owed by the Borrower to all of the Banks; provided that if all or any portion of such excess payment is thereafter recovered from such Bank, such purchase shall be rescinded and the purchase price restored to the extent of such recovery, in proportion with the Banks' respective pro rata shares, but without interest. -30- (f) AUTHORITY TO CHARGE ACCOUNTS. The Agent, if and to the extent payment owed to the Agent or any Bank is not made when due, may charge from time to time against any account of the Borrower with the Agent any amount so due. The Agent agrees promptly to notify the Borrower after any such charge and application made by the Agent provided that the failure to give such notice shall not affect the validity of such charge and application. (g) INTEREST AND FEES. Unless expressly provided for in this Agreement, all computations of interest and fees shall be made on the basis of a 360 day year, in each case for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest or fees are payable; provided, however, that if the use of a 360 day year would cause the interest contracted for, charged, or received hereunder to exceed the Highest Lawful Rate, such computations shall instead be made on the basis of a year of 365 or 366 days, as the case may be. Each determination by the Agent of an interest rate or fee shall be conclusive and binding for all purposes, absent manifest error. (h) PAYMENT DATES. Whenever any payment shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day and such extension of time shall in such case be included in the computation of interest or fees, as the case may be. If the time for payment for an amount payable is not specified in this Agreement or in any other Credit Document, the payment shall be due and payable on demand by the Agent or the applicable Bank. 2.11 TAXES. (a) NO DEDUCTION FOR CERTAIN TAXES. Any and all payments by the Borrower shall be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges, or withholdings, and all liabilities with respect thereto, other than taxes imposed on the income of and franchise taxes imposed on the Agent, any Bank, or the Applicable Lending Office thereof by any jurisdiction in which any such entity is a citizen or resident or any political subdivision of such jurisdiction (all such nonexcluded taxes, levies, imposts, deductions, charges, withholdings, and liabilities being hereinafter referred to as "Taxes"). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable to the Agent, any Bank, or the Applicable Lending Office thereof, (i) the sum payable shall be increased as may be necessary so that, after making all required deductions (including deductions applicable to additional sums payable under this Section 2.11), such Person receives an amount equal to the sum it would have received had no such deductions been made; (ii) the Borrower shall make such deductions; and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law. (b) OTHER TAXES. The Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges, or similar levies which arise from any payment made or from the execution, delivery, or registration of, or otherwise with respect to, this Agreement or the other Credit Documents (other than those which become due as a result of any Bank joining this Agreement as a result of any Assignment and Acceptance, which shall be paid by the Bank which becomes a Bank hereunder as a result of such Assignment and Acceptance). -31- (c) FOREIGN BANK WITHHOLDING EXEMPTION. Each Bank and Issuing Bank that is not incorporated under the laws of the United States of America or a state thereof agrees that it will deliver to the Borrower and the Agent on the date of this Agreement or upon the effectiveness of any Assignment and Acceptance and from time to time thereafter if requested in writing by the Borrower (i) Internal Revenue Service Form W-8ECI, W-8BEN, W-8EXP, or W-8IMY as appropriate, or any successor form prescribed by the Internal Revenue Service, certifying that such Bank is entitled to benefits under an income tax treaty to which the United States is a party which exempts such Bank from withholding tax on payments of interest or certifying that the income receivable pursuant to this Agreement is effectively connected with the conduct of a trade or business in the United States, (ii) Internal Revenue Service Form W-9, as appropriate, or any successor form prescribed by the Internal Revenue Service, and (iii) any other form or certificate required by any taxing authority (including any certificate required by Sections 871(h) and 881(c) of the Internal Revenue Code), certifying that such Bank is entitled to an exemption from tax on payments pursuant to this Agreement or any of the other Credit Documents If an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any delivery required by the preceding sentence would otherwise be required which renders all such forms inapplicable or which would prevent any Bank from duly completing and delivering any such letter or form with respect to it and such Bank advises the Borrower and the Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax, and, in the case of a Form W-9, establishing an exemption from United States backup withholding tax, such Bank shall not be required to deliver such letter or forms.
