(i) If and to the extent that any L/C Funding Lender shall not have made a required amount of a Letter of Credit Advance available to the Letter of Credit Administrative Agent pursuant to the terms of Section 2.02(a), such L/C Funding Lender agrees to pay to the Letter of Credit Administrative Agent forthwith on demand such amount together with interest thereon, for each day from the date of demand by the Issuing Bank from whom such L/C Funding Lender was required to purchase all or a portion of such Letter of Credit Advance until the date such amount is paid to the Letter of Credit Administrative Agent (A) during the first three (3) Business Days after such payment was due, at the Federal Funds Rate and (B) thereafter, at the Federal Funds Rate plus 2% per annum, for its account or the account of such Issuing Bank, as applicable. For so long as amounts are due from an L/C Funding Lender pursuant to this Section 2.02(b), the Issuing Bank to whom such amounts are owed shall have the right without notice to such L/C Funding Lender, to the extent permitted by applicable law, to set-off and appropriate and apply against such amount any and all deposits, in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, at any time held or owing by such Issuing Bank or any branch or agency thereof to or for the credit or the account of such Issuing Bank. If such Lender shall pay to the Letter of Credit Administrative Agent such amount for the account of such Issuing Bank such Lender's Pro Rata Share of the outstanding principal amount of the Letter of Credit Advance so purchased shall constitute a Letter of Credit Advance made by such Lender on the date such payment is made or, if such day is not a Business Day, on the next succeeding Business Day for purposes of this Agreement, and the outstanding principal amount of the Letter of Credit Advance made by such Issuing Bank shall be reduced by such amount on such Business Day. (ii) The failure of any Lender to make a Letter of Credit Advance to be made by it on the date specified in Section 2.02(a) shall not relieve any other Lender of its obligation hereunder to make any Letter of Credit Advance on such date or any other date, but no L/C Funding Lender shall be responsible for any amount greater than its Pro Rata Share with respect to any Letter of Credit Advance solely as a result of the failure of any other Lender required to purchase its Pro Rata Share of such Letter of Credit Advance to make such purchase pursuant to Section 2.02(a).

(h) The Obligations of the Company under this Agreement and any other agreement or instrument relating to any Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement and such other agreement or instrument under all circumstances, including, without limitation, the following circumstances (it being understood that any such payment by the Company is without prejudice to, and does not constitute a waiver of, any rights the Company might have or might acquire as a result of the payment by any Issuing Bank of any draft or the reimbursement by the Company thereof): (i) any lack of validity or enforceability of any Loan Document, any Letter of Credit or any other agreement or instrument relating thereto (all of the foregoing being, collectively, the "L/C Related Documents"); 23 (ii) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations of the Company in respect of any L/C Related Document or any other amendment or waiver of or any consent to departure from all or any of the L/C Related Documents; (iii) the existence of any claim, set-off, defense or other right that the Company may have at any time against any beneficiary or any transferee of a Letter of Credit (or any Persons for which any such beneficiary or any such transferee may be acting), any Issuing Bank, any Lender or any other Person, whether in connection with the transactions contemplated by the L/C Related Documents or any unrelated transaction; (iv) any statement or any other document presented under a Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; (v) payment by any Issuing Bank under a Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; (vi) any exchange, release or non-perfection of any collateral for all or any of the Obligations of the Company in respect of the L/C Related Documents; or (vii) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including, without limitation, any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Company. SECTION 2.06. Interest. (a) Scheduled Interest. The Company shall pay interest on the unpaid principal amount of each Letter of Credit Advance owing to a Lender from the date of such Letter of Credit Advance until such principal amount shall be paid in full, at the following rates per annum: (i) Base Rate Advances. During such periods as such Letter of Credit Advance is a Base Rate Advance, a rate per annum equal at all times to the sum of (x) the Base Rate in effect from time to time plus (y) the Applicable Margin in effect from time to time with respect to such Letter of Credit Advance, payable in arrears quarterly on each Payment Date during such periods and on the date such Base Rate Advance shall be Converted or paid in full. (ii) Eurodollar Rate Advances. During such periods as such Letter of Credit Advance is a Eurodollar Rate Advance, a rate per annum equal at all times during each Interest Period for such Letter of Credit Advance to the sum of (x) LIBOR for such Interest Period for such Letter of Credit Advance plus (y) the Applicable Margin with respect to such Letter of Credit Advance in effect from time to time, payable in arrears on the last day of such Interest Period and on the date such Eurodollar Rate Advance shall be Converted or paid in full. (b) Default Interest. Upon any failure by the Company to make any payment hereunder or under any Letter of Credit Advance Note, the Company shall pay interest on (i) the 24 unpaid principal amount of each Letter of Credit Advance owing to each Lender, payable in arrears on the dates referred to in clause (a)(i) or (a)(ii) above, at a rate per annum equal at all times to 2% per annum above the rate per annum required to be paid on such Letter of Credit Advance pursuant to clause (a)(i) or (a)(ii) above and (ii) to the fullest extent permitted by law, the amount of any interest, fee or other amount payable hereunder or under any Letter of Credit Advance Note that is not paid when due, from the date such amount shall be due until such amount shall be paid in full, payable in full in arrears on any date any such amount shall be paid and on demand, at a rate per annum equal at all times to 2% per annum above the rate per annum then required to be paid, in the case of interest, on the Type of Letter of Credit Advance on which such interest has accrued pursuant to clause (a)(i) or (a)(ii) above and, in all other cases, on Eurodollar Rate Advances pursuant to clause (a)(ii) above (such rate of interest, the "Default Rate"). SECTION 2.07. Interest Rate Determination. (a) The Letter of Credit Administrative Agent shall promptly determine and shall give prompt notice to the Company and the Lenders of the applicable interest rate determined by the Letter of Credit Administrative Agent for purposes of Section 2.06(a)(i) or (ii). (b) If (i) on or prior to the first day of any Interest Period the Letter of Credit Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining LIBOR for such Interest Period or (ii) on or prior to the first day of any Interest Period the Majority Holders with respect to a Letter of Credit Facility advise the Letter of Credit Administrative Agent that LIBOR for such Interest Period will not adequately and fairly reflect the cost to such Majority Holders of making, funding or maintaining their Eurodollar Rate Advances under such Letter of Credit Facility during such Interest Period, the Letter of Credit Administrative Agent shall forthwith give notice thereof (an "Alternate Rate Notice") in respect of such Interest Period to the Company and the Lenders, whereupon until the Letter of Credit Administrative Agent gives notice (an "Alternate Rate Rescission Notice") to the Company and the Lenders that the circumstances giving rise to such Alternate Rate Notice no longer exist (it being understood that the Letter of Credit Administrative Agent will give such notice reasonably promptly after it has knowledge that such circumstances ceased to exist), the interest rate applicable to the Eurodollar Rate Advances under such Letter of Credit Facility shall be determined pursuant to the provisions set forth in Section 2.07(c) or 2.07(d), as applicable. (c) Upon delivery of an Alternate Rate Notice upon the occurrence of conditions set forth in clause (i) of Section 2.07(b), the alternative basis for computing interest on the relevant Eurodollar Rate Advances, which shall be payable in connection with such Interest Period shall be the greater of (x) the Federal Funds Rate plus 0.5% or (y) the Prime Rate, plus in each case the Applicable Margin with respect to such Eurodollar Rate Advances. The Letter of Credit Administrative Agent shall give prompt written notice to the Company and the Lenders of the rate of interest so determined, and its determination thereof shall be prima facie evidence thereof, absent manifest error. (d) Upon delivery of an Alternate Rate Notice upon the occurrence of conditions set forth in clause (ii) of Section 2.07(b), during the 30 days next succeeding the giving of such Alternate Rate Notice, the Company and the Letter of Credit Administrative 25 Agent shall negotiate in good faith in order to arrive at a mutually satisfactory alternative basis (having the written approval of the Majority Holders with respect to the relevant Letter of Credit Facility) for computing interest on the Eurodollar Rate Advances outstanding under such Letter of Credit Facility (the "Alternative Basis Interest Rate"), which shall be payable in connection with such Interest Period in order to compensate the Lenders of the relevant Letter of Credit Advances for the inadequate interest rate resulting from the occurrence of the conditions specified in clause (ii) of this Section 2.07(b). If within such 30-day period, the Company and the Letter of Credit Administrative Agent agree in writing upon the Alternative Basis Interest Rate, such Alternative Basis Interest Rate shall be payable to all Lenders under such Letter of Credit Facility from the commencement of, and only for, the duration of such Interest Period. If the Company and the Letter of Credit Administrative Agent fail to agree upon an Alternative Basis Interest Rate within such 30-day period, the Alternative Basis Interest Rate in connection with such Interest Period payable to each Lender under such Letter of Credit Facility for such Interest Period shall be such Alternative Basis Interest Rate as such Lender shall determine (in a certificate delivered by such Lender to the Letter of Credit Administrative Agent setting forth the basis of the computation of such amount, which certificate shall be conclusive and binding for all purposes, absent manifest error) to be necessary to compensate such Lender for its cost of obtaining (in good faith and using commercially reasonable efforts to minimize the interest cost to the Company) as of the commencement of such Interest Period funds for such Interest Period in an amount equal to the principal amount of such Lender's outstanding Eurodollar Rate Advances plus the Applicable Margin with respect to such Eurodollar Rate Advances. The Letter of Credit Administrative Agent shall notify the Company of each such determination as promptly as practicable. As the negotiations described in this Section 2.07(d) and any resulting Alternative Basis Interest Rate are intended for the direct benefit of the Lenders under the relevant Letter of Credit Facility, the Company expressly covenants and acknowledges (i) that as a result of any such negotiations following the delivery of an Alternate Rate Notice, such Lenders shall not receive a lower rate of interest on their Eurodollar Rate Advances than they would have received had there not been such negotiations, and (ii) that such negotiations shall in no event cause, justify or give rise to any delay or reduction in the payment of interest, principal or other amounts payable by the Company under this Agreement or any Letter of Credit Advance Note. (e) Notwithstanding subsections (a) through (d) above, if (i) the circumstances in clause (i) of subsection (b) above arise in respect of ascertaining LIBOR for the initial Interest Period occurring after any Conversion hereunder of any Base Rate Advances made under any Letter of Credit Facility to Eurodollar Rate Advances under such Letter of Credit Facility or (ii) the circumstances in clause (ii) of subsection (b) above arise in respect of the making, funding or maintaining of Eurodollar Rate Advances to be made, funded or maintained upon the Conversion hereunder of any Base Rate Advances made under any Letter of Credit Facility to Eurodollar Rate Advances under such Letter of Credit Facility, in each such case the provisions in subsections (a) through (d) above shall not apply and such Base Rate Advances shall not be converted to Eurodollar Rate Advances until the Letter of Credit Administrative Agent gives notice to the Company that the circumstances in clause (i) or (ii) of subsection (b), respectively, no longer exist (it being understood that the Letter of Credit Administrative Agent will give such notice reasonably promptly after it has knowledge that such circumstances ceased to exist). Three Business Days after the date of such notification, all such Base Rate Advances shall automatically be Converted to Eurodollar Rate Advances. 26 SECTION 2.08. Conversion of Advances. (a) Subject to the provisions in Section 2.10, Base Rate Advances comprising the same Borrowing shall be automatically Converted into Eurodollar Rate Advances four Business Days after the date such Base Rate Advances are made. (b) The Company may on any Business Day, upon notice to the Letter of Credit Administrative Agent given not later than 11:00 A.M. (New York City time) on the third Business Day prior to the date of the proposed Conversion, Convert Letter of Credit Advances comprising the same Borrowing (provided that the Company shall not convert any Letter of Credit Advance made by an Issuing Bank pursuant to Section 2.02 upon payment of a draft drawn under any Letter of Credit (i) unless all relevant L/C Funding Lenders have purchased their Pro Rata Shares of such Letter of Credit Advance in accordance with Section 2.02, (ii) unless any prepayment of such Letter of Credit Advance required under Section 2.04(c) shall have been received by the relevant Lenders and (iii) at any time when payments to be made under such MT Notes would be subject to foreign exchange restrictions, controls or prohibitions under Argentine law) into Debt evidenced by notes (the "MT Notes") issued under the Medium Term Note Program pursuant to a supplemental indenture substantially in the form attached hereto as Exhibit H-1 in the case of any Short Term Letter of Credit Advances so Converted and in the form attached hereto as Exhibit H-2 in the case of any Long Term Letter of Credit Advances so Converted, with respect to which, in the case of MT Notes issued upon a Conversion of Letter of Credit Advances made by any Lender under the Short Term L/C Series A Facility, the Short Term L/C Series B Facility, the Long Term L/C Series A Facility or the Long Term L/C Series B Facility, each of Perez Companc International S.A., Perez Companc Ecuador and EcuadorTLC S.A. shall be a co-obligor with the Company in respect of all Obligations thereunder, and in the case of MT Notes issued upon a Conversion of Letter of Credit Advances made by any Lender under the Long Term L/C Series D Facility, Pecom Energia S.A., Sucursal Bolivia shall be a co-obligor with the Company in respect of all Obligations thereunder, in each case pursuant to documentation in form and substance satisfactory to such Lender. Any such Conversion shall ratably Convert Letter of Credit Advances comprising the same Borrowing; provided that the Letter of Credit Advances of any Lender that, as of the Conversion Date (as defined below), cannot make all of the representations set forth in Section 8.12 hereof shall not be Converted and such Letter of Credit Advances shall remain Letter of Credit Advances hereunder. On the date of the proposed conversion (the "Conversion Date"), the Company shall, pursuant to the terms of a note purchase agreement substantially in the form attached hereto as Exhibit I, deliver or cause to be delivered to each purchasing Lender an MT Note in the aggregate face amount to be purchased by such Lender (or such Lender's assignee), dated the issue date and registered in such Lender's (or assignee's) name, against delivery to the Company of (i) a settlement agreement, in the form of Exhibit J hereto, transferring all of such Lender's rights, title and interest in respect of all amounts owing to such Lender by the Company in respect of the Letter of Credit Advances to be Converted (other than in respect of interest accrued through (and including) the day preceding the Conversion Date and any other amounts other than principal owing or accrued in respect thereof on the Conversion Date) and (ii) the Letter of Credit Advance Note or Letter of Credit Advance Notes, as applicable, held by such Lender representing or evidencing the obligations of the Company with respect to the Letter of Credit Advances to be converted. Upon the issuance of an MT Note to a Lender (or assignee) pursuant to this Section 2.08(b), the Company shall have no further obligations under this Agreement or any instrument or note delivered hereunder with 27 respect to the Letter of Credit Advances of such Lender (or assignee) Converted pursuant to this Section 2.08(b), and the Note Documents with respect to such MT Notes shall supersede and replace the Loan Documents and all instruments and notes delivered under such Loan Documents with respect to the Letter of Credit Advances of such Lender Converted pursuant to this Section 2.08(b) (without any such act causing the novation of the obligations under the Loan Documents); provided that the obligations of the Company under Sections 2.09, 2.12 and 8.04 shall remain in effect to the extent that any claim thereunder relates to an event arising prior to the Conversion Date. Upon any Conversion of Letter of Credit Advances comprising the same Borrowing pursuant to this Section 2.08(b), the remaining scheduled principal payments in respect of such Letter of Credit Advances shall be ratably reduced in an aggregate amount equal to the amount of such Letter of Credit Advances so Converted. SECTION 2.09. Increased Costs. (a) If, on or 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 Lender (or its Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency, (i) shall subject any Lender (or its Lending Office) to any tax, duty or other charge with respect to one or more of its Eurodollar Rate Advances or its obligation to make Eurodollar Rate Advances, or shall change the basis of taxation of payments to any Lender (or its Lending Office) of the principal of or interest on its Eurodollar Rate Advances or any other amounts due under this Agreement or any Letter of Credit Advance Notes (except for the introduction of, or changes in the rate of, tax on the overall net income of such Lender or its Lending Office, or franchise taxes, imposed by the jurisdiction (or any political subdivision or taxing authority thereof) under the laws of which such Lender is organized, or in which such Lender's principal office or Lending Office is located); or (ii) shall impose, modify or deem applicable any reserve (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System and minimum reserve requirements of the European Central Bank but excluding any such requirement included in an applicable Eurodollar Reserve Percentage), special deposit, insurance assessment or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (or its Lending Office) or shall impose on any Lender (or its Lending Office) or the London interbank market any other condition affecting the purchasing, owning, holding or maintaining of any one or more Eurodollar Rate Advances by such Lender or the obligation of such Lender to make Eurodollar Rate Advances and the result of any of the foregoing is to increase the cost to such Lender (or its Lending Office) of purchasing, owning, holding, maintaining, making or being obligated to make any one or more of its Eurodollar Rate Advances, or to reduce the amount of any sum received or receivable by such Lender (or its Lending Office) under the Agreement and any one or more of its Letter of Credit Advance Notes, by an amount deemed by such Lender to be material (excluding, for purposes of this Section 2.09 any increased costs or any reductions resulting from any Indemnifiable Taxes (as defined in Section 2.12) or Other Taxes (payable by the Company pursuant to Section 2.12)), then, promptly after demand by such Lender (with a copy to the Letter of Credit Administrative Agent), which demand shall be accompanied by a certificate of such Lender setting forth in reasonable detail the circumstances which give rise to such increase or reduction, the amount of the claim and the calculation thereof (and which certificate shall be conclusive and binding for all purposes, absent manifest error), the Company shall, to the extent that it shall not have done 28 so under any other provision of this Agreement, pay to such Lender such additional amount or amounts as will, without duplication, compensate such Lender for such increased cost or reduction. (b) If, on or after the date hereof, any Lender shall determine that the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change in any such 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 any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has the effect of reducing the rate of return on capital of any Lender as a consequence of such Lender's purchasing, owning, maintaining or holding any Eurodollar Rate Advances or such Lender's obligation to make Eurodollar Rate Advances hereunder to a level below that which such Lender could have achieved but for such adoption, change, request or directive (taking into consideration its policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, promptly after demand by such Lender (with a copy to the Letter of Credit Administrative Agent), which demand shall be accompanied by a certificate of such Lender setting forth in reasonable detail the circumstances which give rise to such reduction, the amount of the claim and the calculation thereof (and which certificate shall be conclusive and binding for all purposes, absent manifest error), the Company shall, to the extent that it shall not have already done so under any other provision of this Agreement, pay to such Lender such additional amount or amounts as will, without duplication, compensate such Lender for such reduction. (c) Each Lender will promptly notify the Company and the Letter of Credit Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Lender to compensation pursuant to this Section 2.09. Each Lender will, before requesting compensation for additional amounts pursuant to this Section 2.09, use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to minimize or eliminate the requirement of such compensation by transferring its Letter of Credit Advances, Letter of Credit Advance Notes and its obligations to make Letter of Credit Advances hereunder or to purchase a Pro Rata Share of any Letter of Credit Advances hereunder, as applicable, to a different lending office if such transfer will avoid or reduce the need for compensation for such additional amounts and will not, in the sole judgment of such Lender, be otherwise disadvantageous (economically or otherwise) to such Lender; provided that no Lender shall have any obligation to provide any information as to any possible actions or designations considered and taken or rejected by such Lender or the reasons therefor. A certificate of any Lender claiming compensation under this Section 2.09 and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive and binding for all purposes, absent manifest error. (d) The Company shall not be required to compensate a Lender as provided by this Section 2.09 if the increased cost or reduction in respect of which such claim for additional amounts arises results solely from a requirement which is applicable to the relevant Lender by reason of its financial condition or assets and which is not of general application to similar persons of a similar type in similar circumstances in the same jurisdiction. 29 SECTION 2.10. Illegality. (a) Notwithstanding any other provision of this Agreement, if on or after the date hereof any Lender shall notify the Letter of Credit Administrative Agent that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or any central bank or other Governmental Authority asserts that it is unlawful, for such Lender or its Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances hereunder (after such Lender has used reasonable efforts to transfer its Eurodollar Rate Advances, its Letter of Credit Advance Notes evidencing Eurodollar Rate Advances and its obligations to fund and maintain Eurodollar Rate Advances to a different lending office if such transfer will avoid illegality and shall not, in the sole judgment of such Lender, be disadvantageous (economically or otherwise) to such Lender), each Eurodollar Rate Advance will automatically, upon demand, Convert into a Base Rate Advance and no Base Rate Advances shall be converted into Eurodollar Rate Advances until the circumstances giving rise to such illegality no longer exist; provided that on the date such circumstances no longer exist and all Lenders are able to make Eurodollar Rate Advances hereunder, all Base Rate Advances shall automatically be Converted into Eurodollar Rate Advances three Business Days after such date and all Base Rate Advances made after such date shall automatically be Converted to Eurodollar Rate Advances pursuant to Section 2.08. (b) If any L/C Funding Lender shall notify the Letter of Credit Administrative Agent that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or any central bank or other Governmental Authority asserts that it is unlawful, for such Lender or its Lending Office to perform its obligations hereunder to make any Advances under any Letter of Credit Facility or to fund or maintain any Advances under any Letter of Credit Facility, to the extent the circumstances in subsection (a) do not apply and after such Lender has used reasonable efforts to transfer its Advances, its Letter of Credit Advance Notes evidencing such Advances and its obligations to fund and maintain Advances to a different lending office if such transfer will avoid illegality and shall not, in the sole judgment of such Lender, be disadvantageous (economically or otherwise) to such Lender, (i) the Company shall immediately prepay in full the then outstanding principal amount of such Advances, together with accrued interest thereon; (ii) the obligation of such L/C Funding Lender to make any Advances shall be suspended until such Lender notifies the Company and the Letter of Credit Administrative Agent that the circumstances giving rise to such suspension no longer exist; and (iii) the Company shall deposit into the L/C Collateral Account with respect to the Letter of Credit Facility under which such Advances were made an amount in cash equal to the aggregate principal amount of advances such L/C Funding Lender would otherwise have been required to make under such Letter of Credit Facility pursuant to Section 2.02 (assuming all Letters of Credit outstanding under such Letter of Credit Facility were fully drawn at the time of such suspension). SECTION 2.11. Payments and Computations. (a) The Company shall make each payment hereunder and under the Letter of Credit Advance Notes not later than 11:00 A.M. (New York City time) on the day when due in U.S. dollars to the Letter of Credit Administrative Agent at the Agent's Account in same day funds. With respect to funds paid to the Letter of Credit Administrative Agent, the Letter of Credit Administrative Agent will promptly thereafter cause like funds to be distributed (i) if such payment by the Company is in respect of principal, interest, fees or any other Obligation then payable hereunder and under the Letter of Credit Advance Notes to more than one Lender, to such Lenders for the account of their respective 30 Lending Offices ratably in accordance with the amounts of such respective Obligations then payable to such Lenders and (ii) if such payment by the Company is in respect of any Obligation then payable hereunder to one Lender, to such Lender for the account of its Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to Section 8.06(d), from and after the effective date specified in such Assignment and Acceptance, the Letter of Credit Administrative Agent shall make all payments hereunder and under the Letter of Credit Advance Notes in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves. (b) All interest hereunder shall be computed by the Letter of Credit Administrative Agent on the basis of a year of 360 days and paid for the actual number of days elapsed (including the first day but excluding the last day). Notwithstanding the foregoing, (i) during each Alternate Rate Period, for each day that an alternative basis interest rate is determined pursuant to Section 2.07(c) and such alternative basis interest rate is based upon the Prime Rate as contemplated therein, interest shall be computed on the basis of a year of 365 or 366 days, as the case may be, and paid for the actual number of days elapsed (including the first day but excluding the last day) and (ii) all computations of interest based on the Base Rate shall be made on the basis of a year of 365 or 366 days, as the case may be, and paid for the actual number of days elapsed (including the first day but excluding the last day). Each determination by the Letter of Credit Administrative Agent of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error. (c) Whenever any payment hereunder or under the Letter of Credit Advance Notes shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or facility fee, as the case may be; provided that, if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day. (d) Unless the Letter of Credit Administrative Agent shall have received notice from the Company prior to the date on which any payment is due to the Lenders hereunder that the Company will not make such payment in full, the Letter of Credit Administrative Agent may assume that the Company has made such payment in full to the Letter of Credit Administrative Agent on such date and the Letter of Credit Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent the Company shall not have so made such payment in full to the Letter of Credit Administrative Agent, each Lender shall repay to the Letter of Credit Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Letter of Credit Administrative Agent, at the Federal Funds Rate. 31 SECTION 2.12. Taxes. (a) Any and all payments by the Company hereunder or under any Letter of Credit Advance Note shall be made free and clear of, and without withholding or deduction for or on account of, any Taxes, excluding, (i) in the case of each Lender and the Letter of Credit Administrative Agent, Taxes that are imposed on its overall net income (and franchise taxes imposed in lieu thereof) by any state or foreign jurisdiction under the laws of which such Lender or the Letter of Credit Administrative Agent, as the case may be, is organized or any political subdivision thereof, and (ii) in the case of each Lender, Taxes that are imposed on its overall net income (and franchise taxes imposed in lieu thereof) by the state or foreign jurisdiction of its Lending Office or any political subdivision thereof (all such nonexcluded Taxes in respect of payments hereunder or under any Letter of Credit Advance Notes collectively, "Indemnifiable Taxes"). If any Indemnifiable Taxes are required to be withheld or deducted from any such payment, the Company shall pay such additional amounts as may be necessary to ensure that the amounts received by each Lender or the Letter of Credit Administrative Agent, as the case may be, after such withholding or deduction (and after withholding or deduction on amounts payable under this Section 2.12) shall equal the respective amounts that would have been receivable from the Company (any such additional amounts required to be paid by the Company, "Additional Amounts"). (b) The Company shall promptly pay when due any present or future stamp, court or documentary taxes or any other excise or property taxes, charges or similar levies (including the Personal Property Tax) that arise in any jurisdiction from any payment made hereunder or from the execution, delivery, enforcement or registration of this Agreement or any other document or instrument referred to herein or therein (collectively, "Other Taxes"). (c) The Company agrees to indemnify each Lender and the Administrative Agent for the full amount of Indemnifiable Taxes and Other Taxes, and for the full amount of taxes of any kind imposed or asserted by any jurisdiction on amounts payable under this Section 2.12, imposed on or paid by any such Lender or the Letter of Credit Administrative Agent, as the case may be, and any liability (including penalties, additions to tax interest and expenses) arising therefrom or with respect thereto. Amounts payable by the Company under the indemnity set forth in this subsection (c) shall be paid within 30 days from the date on which the applicable Lender or the Administrative Agent, as the case may be, makes written demand therefor. (d) Within 30 days after the date of any payment of Taxes under this Section 2.12, the Company will notify the Letter of Credit Administrative Agent of such payment and, at the request of the Letter of Credit Administrative Agent, furnish the Letter of Credit Administrative Agent at its address referred to in Section 8.02 the original or a certified copy of a receipt evidencing payment thereof.

Such service may be made by mailing or delivering a copy of such process to the Company in care of the Process Agent at the Process Agent's above address, and the Company hereby irrevocably authorizes and directs the Process Agent to accept such service on its behalf. As an alternative method of service, the Company also 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 the Company at its address specified in Section 8.02.

SECTION 8.10. Judgment Currency. (a) If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due hereunder or under the Letter of Credit Advance Notes in U.S. dollars into another currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which, in accordance with normal banking procedures, the Letter of Credit Administrative Agent or each Lender, as the case may be, could purchase U.S. dollars with such other currency in New York City at 11:00 A.M. (New York City time) on the Business Day preceding that on which final, nonappealable judgment is given. (b) The obligations of the Company in respect of any sum due to the Letter of Credit Administrative Agent or any of the Lenders hereunder or under the Letter of Credit Advance Notes shall, notwithstanding any judgment in a currency other than U.S. dollars, be discharged only to the extent that on the Business Day following receipt by the Letter of Credit Administrative Agent or such Lender, as the case may be, of any sum adjudged to be so due in such other currency, the Letter of Credit Administrative Agent or any Lender, as the case may be, may, in accordance with normal, reasonable banking procedures, purchase U.S. dollars with such other currency. If the amount of U.S. dollars so purchased is less than the sum originally due to the Letter of Credit Administrative Agent or such Lender, in U.S. dollars, the Company agrees, to the fullest extent that it may effectively do so, as a separate obligation and notwithstanding any such judgment, to indemnify the Letter of Credit Administrative Agent or such Lender, as the case may be, against such loss.

SECTION 8.11. Waiver of Jury Trial. Each of the Company, the Letter of Credit Administrative Agent and the Lenders hereby irrevocably waives all right to trial by jury in any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or the Letter of Credit Advance Notes or the actions of the Letter of Credit Administrative Agent or any Lender in the negotiation, administration, performance or enforcement thereof.
