If any payment of principal on any Loan is not made when due after the expiration of the grace period therefor provided in SECTION 7.1 (whether by acceleration or otherwise), such Loan shall bear interest (computed on the basis of a year of 360, 365 or 366 days, as applicable, and actual days elapsed) from the date such payment was due until such principal then due is paid in full, payable on demand, at a rate per annum equal to: (a) for any Base Rate Loan the lesser of (i) the Highest Lawful Rate or (ii) the sum of two percent (2%) per annum plus the Base Rate from time to time in effect (but not less than the Base Rate in effect at maturity) plus the Applicable Margin; (b) for any LIBOR Loan the lesser of (i) the Highest Lawful Rate or (ii) the sum of two percent (2%) per annum plus the rate of interest in effect thereon at the time of such default until the end of the Interest Period for such Loan and, thereafter, at a rate per annum equal to the sum of two percent (2%) per annum plus the Base Rate from time to time in effect (but not less than the Base Rate in effect at maturity) plus the Applicable Margin; and (c) for any unpaid Reimbursement Obligations, the lesser of (i) the Highest Lawful Rate or (ii) the sum of two percent (2%) per annum plus the Base Rate from time to time in effect (but not less than the Base Rate in effect at maturity) plus the Applicable Margin. It is the intention of the Agent and each Lender to conform strictly to usury laws applicable to it. Accordingly, if the transactions contemplated hereby or the Loans or the Reimbursement Obligations would be usurious as to the Agent or the Lenders under laws applicable to it (including the laws of the United States of America and the State of Texas or any other jurisdiction whose laws may be mandatorily applicable to the Agent or such Lender notwithstanding the other provisions of this Agreement, the Notes or any other Credit Document), then, in that event, notwithstanding anything to the contrary in this Agreement, the Notes or any other Credit Document, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under laws applicable to the Lenders that is contracted for, taken, reserved, charged or received by the Lenders under this Agreement, the Notes or any other Credit Document or otherwise shall under no circumstances exceed the Highest Lawful Rate, and any excess shall be credited by the applicable Lender on the principal amount of the 20 applicable Note or to the Reimbursement Obligations (or, if the principal amount of such Note and all Reimbursement Obligations owed to such Lender shall have been paid in full, refunded by such Lender to the Borrower); (ii) in the event that the maturity of the Notes is accelerated by reason of an election of the holder or holders thereof resulting from any Event of Default hereunder or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under laws applicable to the Lenders may never include more than the Highest Lawful Rate, and excess interest, if any, provided for in this Agreement, the Notes, any other Credit Document or otherwise shall be automatically canceled by the applicable Lenders as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by the applicable Lenders on the principal amount of the applicable Notes or Reimbursement Obligations (or if the principal amounts thereof shall have been paid in full, refunded by the applicable Lender to the Borrower); and (iii) if at any time the interest provided hereunder, together with any other fees payable pursuant to this Agreement, the Notes or any other Credit Document and deemed interest under applicable law, exceeds the amount that would have accrued at the Highest Lawful Rate, the amount of interest and any such fees to accrue to the Lenders hereunder and thereunder shall be limited to the amount which would have accrued at the Highest Lawful Rate, but any subsequent reductions shall not reduce the interest to accrue to the Lenders hereunder and thereunder below the Highest Lawful Rate until the total amount of interest accrued pursuant hereto and thereto and such fees deemed to be interest equals the amount of interest which would have accrued to the Lenders if a varying rate per annum equal to the interest hereunder had at all times been in effect plus the amount of fees which would have been received but for the effect of this SECTION 2.7. The Agent and the Lenders hereby elect to determine the applicable rate ceiling under Section 303.201 of the Texas Finance Code Ann. (Vernon 1998) by the weekly rate ceiling from time to time in effect, subject to the Agent's and the Lenders' right subsequently to change such method in accordance with applicable law. In the event the Loans and all Reimbursement Obligations are paid in full by the Borrower prior to the Maturity Date and the interest received for the actual period of the existence of the Loans or the Reimbursement Obligations exceeds the Highest Lawful Rate, the applicable Lenders shall refund to the Borrower the amount of the excess or shall credit the amount of the excess against amounts owing under the Loans and none of the Lenders shall be subject to any of the penalties provided by law for contracting for, taking, reserving, charging or receiving interest in excess of the Highest Lawful Rate. The provisions of Chapter 346 of Tex. Finance Code Ann. (Vernon 1998), regulating certain revolving credit accounts shall not apply to this Agreement or any of the Notes. Section 2.8 Maturity of Loans. Each Loan, together with accrued and unpaid interest thereon and all other fees then due and owing under any Credit Document, shall mature and become due and payable on the Maturity Date. Section 2.9 Optional Prepayments. The Borrower shall have the privilege of prepaying the Term Loan without premium or penalty in whole or in part at any time, provided that, each voluntary partial prepayment of the Term Loan must be in a principal amount of not less than $5,000,000, or a greater integral multiple of $1,000,000. If the Borrower is prepaying LIBOR Loans, it shall give the Agent notice of such prepayment no later than 11:00 a.m. at least two (2) Business Days before the proposed prepayment date. All prepayments of Loans shall be accompanied by accrued interest thereon, together with, if such Loans being prepaid are LIBOR Loans, any applicable breakage fees and funding losses pursuant to SECTION 2.12. The Borrower 21 may direct the application of any optional prepayment hereunder to the Base Rate Loans or LIBOR Loans outstanding. Section 2.10 Mandatory Prepayments of Loans. (a) If the aggregate amount of outstanding L/C Obligations shall at any time for any reason exceed the L/C Commitment Amount then in effect, the Borrower shall, immediately and without notice or demand, pay the amount of such excess to the Agent for the ratable benefit of the Lenders as a pre-funding of cash collateral for Letters of Credit to the extent such Letters of Credit are not fully cash collateralized at the time of such pre-funding. (b) Any mandatory prepayment of Loans pursuant to this Agreement shall not be limited by the notice provision for prepayments set forth in SECTION 2.9, but immediately upon determining the need to make any such prepayment, the Borrower shall notify the Agent of such required prepayment. Each such prepayment shall be accompanied by a payment of all accrued and unpaid interest on the Loans prepaid and any applicable breakage fees and funding losses pursuant to SECTION 2.12. (c) Proceeds of the initial Loan shall be used in accordance with SECTION 2.10(c) of the Existing Credit Agreement. Section 2.11 The Notes. The Term Loans outstanding to the Borrower from the Lenders shall be evidenced by promissory notes of the Borrower payable to each of the Lenders and the Agent in the form of EXHIBIT 2.11 (each such promissory note, together with any replacements thereof, a "TERM NOTE", and collectively, the "NOTES"). Each holder of a Note shall record on its books and records or on a schedule to the Note the amount of each Loan outstanding from it to the Borrower, all payments of principal and interest and the principal balance from time to time outstanding thereon, the type of such Loan and, if a LIBOR Loan, the Interest Period and interest rate applicable thereto. Such record, whether shown on the books and records of a holder of a Note or on a schedule to its Note, shall be prima facie evidence as to all such matters; provided, however, that the failure of any holder to record any of the foregoing or any error in any such record shall not limit or otherwise affect the obligation of the Borrower to repay all Loans outstanding to it hereunder, together with accrued interest thereon. At the request of any holder of a Note and upon such holder tendering to the Borrower the Note to be replaced, the Borrower shall furnish a new Note to such holder to replace any outstanding Note and at such time the first notation appearing on the schedule on the reverse side of, or attached to, such new Note shall set forth the aggregate unpaid principal amount of all Loans, if any, then outstanding thereon. Section 2.12 Breakage Fees. If any Lender incurs any loss, cost or expense (excluding any loss of anticipated profit, but including, without limitation, any loss, cost, expense or premium reasonably incurred by reason of the liquidation or re-employment of deposits or other funds acquired by such Lender to fund or maintain any LIBOR Loan or the relending or reinvesting of such deposits or amounts paid or prepaid to the Lenders) as a result of any of the following events other than any such occurrence as a result of a change of circumstance described in SECTIONS 8.1 or 8.2: 22 (i) any payment, prepayment or conversion of a LIBOR Loan on a date other than the last day of its Interest Period (whether by acceleration, prepayment or otherwise); (ii) any failure to make a principal payment of a LIBOR Loan on the due date therefor; or (iii) any failure by the Borrower to continue, prepay or convert to a LIBOR Loan on the date specified in a notice given pursuant to SECTION 2.4(a) (other than by reason of a default of a Lender), then the Borrower shall pay to such Lender such amount as will reimburse such Lender for such loss, cost or expense. If any Lender makes such a claim for compensation, it shall provide to the Borrower a certificate executed by an officer of such Lender setting forth the amount of such loss, cost or expense in reasonable detail (including an explanation of the basis for and the computation of such loss, cost or expense) no later than 120 days after the event giving rise to the claim for compensation, and the amounts shown on such certificate shall be conclusive and binding absent manifest error. Within ten (10) days of receipt of such certificate, the Borrower shall pay to such Lender such amount as will compensate such Lender for such loss, cost or expense as provided herein, unless such Lender has failed to timely give notice to the Borrower of such claim for compensation as provided herein, in which event the Borrower shall no longer be obligated to pay such claim. Section 2.13 L/C Commitment Terminations. The Borrower shall have the right at any time and from time to time, upon five (5) Business Days' prior and irrevocable written notice to the Agent, to terminate or reduce the L/C Commitments without premium or penalty, in whole or in part, any partial termination to be (i) in an amount not less than $1,000,000 as determined by the Borrower, and (ii) allocated ratably among the Lenders in proportion to their respective L/C Commitments, as applicable; provided that the L/C Commitment Amount may not be reduced to an amount less than the sum of the aggregate amount of outstanding L/C Obligations, after giving effect to payments on such proposed termination or reduction date, unless the Borrower provides to the Lenders or the Agent, as applicable, cash collateral in an amount sufficient to cover such shortage or back-to-back letters of credit from a financial institution satisfactory to all of the Lenders in an amount equal to the undrawn face amount of any applicable outstanding Letters of Credit with an expiry date of at least five (5) days after the expiry date of any applicable Letter of Credit and which provide that the Lenders may make a drawing thereunder in the event that it pays a drawing under such Letter of Credit. Any termination of the L/C Commitments pursuant to this SECTION 2.13 is permanent and may not be reinstated. The Agent shall give prompt notice to each Lender of any such termination of the L/C Commitments. Section 2.14 Agent Reliance on Borrower Payment. Except as otherwise provided under SECTION 2.2(c), unless the Borrower has notified the Agent prior to the date any payment or prepayment to be made by it is due (or if the Borrower has given notice of its intention to prepay a Loan on such date), that it does not intend to make such payment or prepayment, the Agent may assume that the Borrower has made such payment when due (or on the date stated in its prepayment notice) and in reliance upon such assumption may (but shall not be required to) make available to each Lender its Percentage of such payment. If such payment was not in fact made to the Agent in immediately available funds, then each Lender shall promptly on demand 23 repay to the Agent the amount of such assumed payment made available to such Lender, together with interest thereon in respect of each day from and including the date such amount was made available by the Agent to such Lender to the date such amount is repaid to the Agent at the Federal Funds Rate. SECTION 3. FEES AND PAYMENTS. Section 3.1 Fees. (a) Letter of Credit Fees. Commencing upon the Effective Date, the Borrower shall pay to the Agent quarterly in arrears (pro rated, if necessary for any portion of such quarter) for the ratable account of the Lenders (based on their respective Percentages) a non-refundable fee for any Letter of Credit equal to the greater of (x) $125 per quarter, or (y) the face amount of such Letter of Credit multiplied by a rate equal to 0.50% per annum, calculated on the basis of a 365/366-day year and actual days in the period and based on the then scheduled expiry date of the Letter of Credit. Thereafter, such fees shall be payable by the Borrower in arrears on the last Business Day of each calendar quarter of each year commencing with the next succeeding calendar quarter, with the last such payment on the date any such Letter of Credit expires. In addition, the Borrower shall pay to the Agent solely for the Agent's account, in connection with each Letter of Credit, reasonable administrative and amendment fees and expenses for letters of credit established by the Agent from time to time in accordance with its customary practices and as agreed between the Agent and the Borrower and a fronting fee of 1/8% of the face amount of each Letter of Credit (other than the Existing L/Cs). All fees paid to the Agent or any other parties before the date of this Agreement in respect of any Existing L/Cs are solely for the account of those parties without any accounting for them or sharing of them with the Agent or Lenders notwithstanding any contrary provision in this Agreement. (b) Agent Fees. The Borrower shall pay to the Agent the fees agreed to from time to time by the Borrower and the Agent. Section 3.2 Place and Application of Payments.

Any payments received by the Agent from the Borrower after 2:00 p.m. shall be deemed to have been received on the next Business Day. Section 3.3 Withholding Taxes. (a) Payments Free of Withholding. Except as otherwise required by law and subject to SECTION 3.3(b), each payment by the Borrower to the Agent or any Lender under this Agreement or any other Credit Document shall be made without withholding for or on account of any present or future taxes (other than overall net income taxes on the recipient) imposed by or within the jurisdiction in which the Borrower is domiciled, any jurisdiction from which the Borrower makes any payment, or (in each case) any political subdivision or taxing authority thereof or therein, excluding, in the case of each Lender and the Agent, taxes, assessments or other governmental charges 24 (i) imposed on, based upon, or measured by its income, and branch profits, franchise and similar taxes imposed on it, by any jurisdiction in which the Agent or such Lender, as the case may be, is incorporated or maintains its principal place of business or Lending Office or which subjects the Agent or such Lender to tax by reason of a connection between the taxing jurisdiction and the Agent or such Lender (other than a connection resulting from the transactions contemplated by this Agreement); (ii) imposed as a result of a connection between the taxing jurisdiction and the Agent or such Lender, as the case may be, other than a connection resulting from the transactions contemplated by this Agreement; (iii) imposed as a result of the transfer by such Lender of its interest in this Agreement or any other Credit Document or a designation by such Lender (other than pursuant to SECTION 3.3(d) hereof) of a new Lending Office (other than taxes imposed as a result of any change in treaty, law or regulation after such transfer of the Lender's interest in this Agreement or any Credit Document or designation of a new Lending Office); (iv) imposed by the United States of America upon a Lender organized under the laws of a jurisdiction outside of the United States, except to the extent that such tax is imposed or increased as a result of any change in applicable law, regulation or treaty (other than any addition of or change in any "anti-treaty shopping," "limitation of benefits," or similar provision applicable to a treaty) after the Effective Date, in the case of each Lender originally a party hereto or, in the case of any Purchasing Lender (as defined in SECTION 10.10), after the date on which it becomes a Lender; (v) which would not have been imposed but for (a) the failure of the Agent or any Lender, as the case may be, to provide (x) an Internal Revenue Service Form 1001 or 4224, as the case may be, or any substitute or successor form prescribed by the Internal Revenue Service pursuant to SECTION 3.3(b) below, or (y) any other certification, documentation or proof which is reasonably requested by the Borrower, or (b) a determination by a taxing authority or a court of competent jurisdiction that a certification, documentation or other proof provided by such Lender or the Agent to establish an exemption from such tax, assessment or other governmental charge is false (all such non-excluded taxes, assessments or other governmental charges and liabilities being hereinafter referred to as "INDEMNIFIED TAXES"). If any such withholding is so required, the Borrower shall make the withholding, pay the amount withheld to the appropriate governmental authority before penalties attach thereto or interest accrues thereon and forthwith pay such additional amount as may be necessary to ensure that the net amount actually received by the Agent and each Lender is free and clear of such Indemnified Taxes (including Indemnified Taxes on such additional amount) and is equal to the amount that the Agent or such Lender (as the case may be) would have received had such withholding not been made. If the Agent or any Lender pays any amount in respect of any Indemnified Taxes, penalties or interest, the Borrower shall reimburse the Agent or that Lender for the payment on demand in the currency in which such payment was made. If the Borrower pays any Indemnified Taxes, penalties or interest, it shall deliver official tax receipts evidencing the payment or certified copies thereof, or other satisfactory evidence of payment if such tax receipts have not yet been received by the Borrower 25 (with such tax receipts to be promptly delivered when actually received), to the Agent or the Lender on whose account such withholding was made (with a copy to the Agent if not the recipient of the original) within fifteen (15) days of such payment. (b) U.S. Withholding Tax Exemptions. Each Lender that is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) shall submit to the Borrower and the Agent on or before the Effective Date, two duly completed and signed copies of either Form 1001 (entitling such Lender to a complete exemption from withholding under the Code on all amounts to be received by such Lender, including fees, pursuant to the Credit Documents) or Form 4224 (relating to all amounts to be received by such Lender, including fees, pursuant to the Credit Documents) of the Internal Revenue Service. Thereafter and from time to time, each Lender shall submit to the Borrower and the Agent such additional duly completed and signed copies of one or the other of such forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may be (i) notified by the Borrower, directly or through the Agent, to such Lender, and (ii) required under then-current United States law or regulations to avoid United States withholding taxes on payments in respect of all amounts to be received by such Lender, including fees, pursuant to the Credit Documents. Upon the request of the Borrower, each Lender that is a United States person shall submit to the Borrower a certificate to the effect that it is such a United States person. Each such Lender shall make written demand on the Borrower for indemnification or compensation hereunder not later than 120 days after the earlier of (i) the date on which such Lender or Agent makes payment of Indemnified Taxes, or (ii) the date on which the relevant taxing authority or other governmental authority makes written demand upon such Lender or the Agent for payment of Indemnified Taxes; provided that any failure of a Lender or the Agent to give the Borrower timely notice as provided herein shall not relieve the Borrower of any obligation which it has to pay such claim for compensation for such indemnification. (c) Inability of Lender to Submit Forms. If any Lender determines, as a result of any change in applicable law, regulation or treaty, or in any official application or interpretation thereof, that it is unable to submit to the Borrower or the Agent any form or certificate that such Lender is obligated to submit pursuant to SECTION 3.3(b) or that such Lender is required to withdraw or cancel any such form or certificate previously submitted or any such form or certificate otherwise becomes ineffective or inaccurate, such Lender shall promptly notify the Borrower and the Agent of such fact and the Lender shall to that extent not be obligated to provide any such form or certificate and will be entitled to withdraw or cancel any affected form or certificate, as applicable. (d) Refund of Taxes. If any Lender or the Agent receives a refund of any Indemnified Tax or any tax referred to in SECTION 10.3 with respect to which the Borrower has paid any amount pursuant to this SECTION 3.3 or SECTION 10.3, such Lender or the Agent shall pay the amount of such refund (including any interest received with respect thereto) to the Borrower.

When any Event of Default other than those described in subsections (f) or (g) of SECTION 7.1 has occurred and is continuing, the Agent shall, by notice to the Borrower: (a) if so directed by the Majority Lenders, terminate the remaining L/C Commitments and all other obligations of the Lenders hereunder on the date stated in such notice (which may be the date thereof); (b) if so directed by the Majority Lenders, declare the principal of and the accrued interest on all outstanding Notes to be forthwith due and payable and thereupon all outstanding Notes, including both principal and interest thereon, shall be and become immediately due and payable together with all other amounts payable under the Credit Documents without further demand, presentment, protest or notice of any kind, including, but not limited to, notice of intent to accelerate and notice of acceleration, each of which is expressly waived by the Borrower; and (c) if so directed by the Majority Lenders, demand that the Borrower immediately pay to the Agent (to be held by the Agent pursuant to SECTION 7.4) the full amount then available for drawing under each or any outstanding Letter of Credit to the extent 46 any such Letter of Credit is not already cash collateralized; and the Borrower agrees to immediately make such payment and acknowledges and agrees that neither the Agent nor the Lenders would have an adequate remedy at law for failure by the Borrower to honor any such demand and that the Agent, for the benefit of the Lenders shall have the right to require the Borrower to specifically perform such undertaking whether or not any drawings or other demands for payment have been made under any Letter of Credit. The Agent, after giving notice to the Borrower pursuant to SECTION 7.1(c) or (d) or this SECTION 7.2, shall also promptly send a copy of such notice to the other Lenders, but the failure to do so shall not impair or annul the effect of such notice.

When any Event of Default described in subsections (f) or (g) of SECTION 7.1 has occurred and is continuing with respect to the Borrower, then (i) all outstanding Notes shall immediately and automatically become due and payable together with all other amounts payable under the Credit Documents without presentment, demand, protest or notice of any kind, each of which is expressly waived by the Borrower, (ii) all obligations of the Agent or any Lender to extend further credit pursuant to any of the terms hereof shall immediately terminate, and (iii) the Borrower shall immediately pay to the Agent (to be held by the Agent pursuant to SECTION 7.4) the full amount then available for drawing under all outstanding Letters of Credit to the extent any such Letter of Credit is not already cash collateralized, the Borrower acknowledging and agreeing that neither the Agent nor the Lenders would have an adequate remedy at law for failure by the Borrower to honor any such demand and that the Agent and the Lenders shall have the right to require the Borrower to specifically perform such undertaking whether or not any drawings or other demands for payment have been made under any of the Letters of Credit. Section 7.4 Collateral for Undrawn Letters of Credit. (a) If the prepayment of the amount available for drawing under any or all outstanding Letters of Credit is required under SECTION 7.2 or 7.3, the Borrower shall forthwith pay the amount required to be so prepaid, to be held by the Agent as provided in subsection (b) below. (b) All amounts prepaid pursuant to subsection (a) above shall be held by the Agent in a separate collateral account (such account, and the credit balances, properties and any investments from time to time held therein, and any substitutions for such account, any certificate of deposit or other instrument evidencing any of the foregoing and all proceeds of and earnings on any of the foregoing being collectively called the "COLLATERAL ACCOUNT") as security for, and for application by the Agent (to the extent available) to, the reimbursement of any drawing under any Letter of Credit then or thereafter made by the Agent, and to the payment of the unpaid balance of any Loans and all other due and unpaid Obligations (collectively, the "COLLATERALIZED OBLIGATIONS"). The Collateral Account shall be held in the name of and subject to the exclusive dominion and control of the Agent, for the benefit of the Lenders, as pledgee hereunder. If and when requested by the Borrower, the Agent shall invest and reinvest funds held in the Collateral Account from time to time in Cash Equivalents specified from time to time by the Borrower, provided that the Agent is irrevocably authorized to sell investments held in the Collateral Account when and as required to make payments out of the Collateral Account for application to Collateralized Obligations due and owing from the Borrower to the Lenders.

After the occurrence of and during the continuance of an Event of Default, any payment to the Agent hereunder or from the proceeds of any cash collateral shall be applied as the Agent and the Lenders shall elect in their sole discretion. SECTION 8. CHANGE IN CIRCUMSTANCES. Section 8.1 Change of Law. Notwithstanding any other provisions of this Agreement or any Note, if at any time any change in applicable law or regulation or in the interpretation thereof makes it unlawful for any Lender to make or continue to maintain LIBOR Loans or to give effect to its obligations as contemplated hereby, such Lender shall promptly give written notice thereof (which notice shall specify in reasonable detail the basis therefor) to the Borrower and such Lender's obligations to make, continue or convert Loans into LIBOR Loans under this Agreement shall be suspended until it is no longer unlawful for such Lender to make or maintain LIBOR Loans. The Borrower shall prepay on demand the outstanding principal amount of any such affected LIBOR Loans, together with all interest accrued thereon and all other amounts then due and payable to such Lender under this Agreement; provided, however, subject to all of the terms and conditions of this Agreement, the Borrower may then elect to borrow the principal amount of the affected LIBOR Loans from such Lender by means of Base Rate Loans from such Lender that shall not be made ratably by the Lenders but only by such affected Lender. Section 8.2 Unavailability of Deposits or Inability to Ascertain LIBOR Rate. If on or before the first day of any Interest Period for any LIBOR Loan the Agent determines (after consultation with other Lenders) that, due to changes in circumstances since the date hereof, adequate and fair means do not exist for determining the Adjusted LIBOR Rate or such rate will not accurately reflect the cost to the Majority Lenders of funding LIBOR Loans for such Interest Period, the Agent shall give written notice of such determination (which notice shall specify in reasonable detail the basis therefor) to the Borrower and the Lenders, whereupon until the Agent notifies the Borrower and Lenders that the circumstances giving rise to such suspension no longer exist, the obligations of the Lenders to make, continue or convert Loans into LIBOR Loans shall be suspended. Section 8.3 Increased Cost and Reduced Return. (a) If, on or after the Effective Date, the adoption of 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 48 or administration thereof, or compliance by any Lender (or its Lending Office), including the Agent in its capacity as the issuer of Letters of Credit, with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency: (i) subjects any Lender of that type (or its Lending Office) to any tax, duty or other charge related to any LIBOR Loan, Letter of Credit or Reimbursement Obligation, or its participation in any thereof, or its obligation to advance or maintain LIBOR Loans, issue Letters of Credit or to participate therein, or shall change the basis of taxation of payments to any Lender (or its Lending Office) of the principal of or interest on its LIBOR Loans, Letters of Credit or participations therein, or any other amounts due under this Agreement related to its LIBOR Loans, Letters of Credit, Reimbursement Obligations or participations therein, or its obligation to make LIBOR Loans, issue Letters of Credit or acquire participations therein (except for changes in the rate of tax on the overall net income of such Lender or its Lending Office imposed by the jurisdiction in which such Lender's principal executive office or Lending Office is located); or (ii) imposes, modifies or deems applicable any reserve, special deposit or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System) against assets of, deposits with or for the account of, or credit extended by, any Lender of that type (or its Lending Office) or imposes on any Lender of that type (or its Lending Office) or on the interbank market any other condition affecting its LIBOR Loans, its Letters of Credit, any Reimbursement Obligation owed to it or its participation in any thereof, or its obligation to advance or maintain LIBOR Loans, issue Letters of Credit or to participate in any thereof; and the result of any of the foregoing is to increase the cost to such Lender (or its Lending Office) of advancing or maintaining any LIBOR Loan, issuing or maintaining a Letter of Credit or participation therein, or to reduce the amount of any sum received or receivable by such Lender (or its Lending Office) in connection therewith under this Agreement or its Note(s), by an amount deemed by such Lender to be material, then, within fifteen (15) days after demand in reasonable detail by such Lender (with a copy to the Agent), the Borrower shall be obligated to pay to such Lender such additional amount or amounts as will compensate such Lender for such increased cost or reduction. (b) If, after the Effective Date, the Agent or any Lender shall have determined that the adoption after the Effective Date of any applicable law, rule or regulation regarding capital adequacy, or any change therein (including, without limitation, any revision in the Final Risk-Based Capital Guidelines of the Board of Governors of the Federal Reserve System (12 CFR Part 208, Appendix A; 12 CFR Part 225, Appendix A) or of the Office of the Comptroller of the Currency (12 CFR Part 3, Appendix A), or in any other applicable capital adequacy rules heretofore adopted and issued by any governmental authority), 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 the Agent or any Lender (or its Lending Office) with 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 or would have the effect of reducing the rate of return on such Lender's capital, or on the capital of any corporation controlling such Lender, as a consequence of its 49 obligations hereunder to a level below that which such Lender could have achieved but for such adoption, change or compliance (taking into consideration such Lender's policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, within fifteen (15) days after demand in reasonable detail by such Lender (with a copy to the Agent), the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction. (c) The Agent and each Lender that determines to seek compensation under this SECTION 8.3 shall notify the Borrower and, in the case of a Lender other than the Agent, the Agent of the circumstances that entitle the Agent or Lender to such compensation and will designate a different Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole judgment of such Lender, be otherwise disadvantageous to it; provided that, the foregoing shall not in any way affect the rights of any Lender or the obligations of the Borrower under this SECTION 8.3, and provided further that no Lender shall be obligated to make its LIBOR Loans hereunder at any office located in the United States. A certificate of any Lender claiming compensation under this SECTION 8.3 and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error and shall be deemed to contain a representation by the Lender issuing such certificate that: (i) such Lender has used, in its sole judgment, reasonable efforts to minimize said compensation, and (ii) the increased costs and charges are common to substantially all of the comparable or similarly situated loan customers of such Lender and are not unique to the Borrower. In determining such amount, such Lender may use any reasonable averaging and attribution methods. Section 8.4 Lending Offices. The Agent and each Lender may, at its option, elect to make its Loans hereunder at the Lending Office for each type of Loan available hereunder or at such other of its branches, offices or Affiliates as it may from time to time elect and designate in a written notice to the Borrower and the Agent subject to SECTION 8.3(c). Section 8.5 Discretion of Lender as to Manner of Funding. Notwithstanding any other provision of this Agreement, each Lender shall be entitled to fund and maintain its funding of all or any part of its Loans 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 each Lender had actually funded and maintained each LIBOR Loan through the purchase of deposits in the Eurodollar interbank market having a maturity corresponding to such Loan's Interest Period and bearing an interest rate equal to LIBOR for such Interest Period. Section 8.6 Substitution of Lender. If (i) any Lender has demanded compensation or given notice of its intention to demand compensation under SECTION 8.3, or (ii) the Borrower is required to pay any additional amount to any Lender under SECTION 2.12, the Borrower shall have the right, with the assistance of the Agent, to seek a substitute lender or lenders reasonably satisfactory to the Agent (which may be one or more of the Lenders) to replace such Lender under this Agreement. The Lender to be so replaced shall cooperate with the Borrower and substitute lender to accomplish such substitution on the terms of SECTION 10.10, as applicable; provided that all the L/C Commitments of such Lender are replaced and such Lender is paid any amounts which it is owed pursuant to SECTIONS 2.12, 3.3, 7.6, 8.3 and 10.3. Any such replaced Lender shall retain the benefits of SECTIONS 3.3 and 10.13. 50 SECTION 9. THE AGENT. Section 9.1 Appointment and Authorization. Each Lender hereby appoints Bank of America, N.A. as the Agent under the Credit Documents and hereby authorizes the Agent to take such action as Agent on each of its behalf and to exercise such powers under the Credit Documents as are delegated to the Agent, by the terms thereof, together with such powers as are reasonably incidental thereto. Section 9.2 Rights and Powers. The Agent shall have the same rights and powers under the Credit Documents as any other Lender and may exercise or refrain from exercising such rights and powers as though it were not an Agent, and the Agent and its respective Affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower or any of its Subsidiaries or Affiliates as if it were not an Agent under the Credit Documents. The term Lender as used in all Credit Documents, unless the context otherwise clearly requires, includes the Agent in its individual capacity as a Lender. Section 9.3 Action by Agent. The obligations of the Agent under the Credit Documents are only those expressly set forth therein. Without limiting the generality of the foregoing, the Agent shall not be required to take any action concerning any Default or Event of Default, except as expressly provided in SECTIONS 7.2 and 7.5. Unless and until the Majority Lenders give such direction the Agent may, except as otherwise expressly provided herein or therein, take or refrain from taking such actions as it deems appropriate and in the best interest of all the Lenders. In no event, however, shall the Agent be required to take any action in violation of applicable law or of any provision of any Credit Document, and the Agent shall in all cases be fully justified in failing or refusing to act hereunder or under any other Credit Document unless it first receives any further assurances of its indemnification from the Lenders that it may require, including prepayment of any related expenses and any other protection it requires against any and all costs, expenses, and liabilities it may incur in taking or continuing to take any such action. The Agent shall be entitled to assume that no Default or Event of Default exists unless notified in writing to the contrary by a Lender or the Borrower. In all cases in which the Credit Documents do not require the Agent to take specific action, the Agent shall be fully justified in using its discretion in failing to take or in taking any action thereunder. Any instructions of the Majority Lenders, or of any other group of Lenders called for under specific provisions of the Credit Documents, shall be binding on all the Lenders and holders of Notes. Section 9.4 Consultation with Experts. The Agent may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts. Section 9.5 Indemnification Provisions; Credit Decision. Neither the Agent nor any of its directors, officers, agents, Affiliates, or employees shall be liable for any action taken or not taken by them in connection with the Credit Documents (i) with the consent or at the request of the Majority Lenders or all the Lenders where unanimity is required or (ii) in the absence of their own gross negligence or willful misconduct. Neither the Agent nor any of its directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into or verify (i) any statement, warranty or representation made in connection with this Agreement, any other Credit Document or any Loan or Letter of Credit; (ii) the performance or observance of 51 any of the covenants or agreements of the Borrower or any Subsidiary contained herein or in any other Credit Document; (iii) the satisfaction of any condition specified in SECTION 4, except receipt of items required to be delivered to the Agent; or (iv) the validity, effectiveness, genuineness, enforceability, perfection, value, worth or collectibility hereof or of any other Credit Document or of any other documents or writing furnished in connection with any Credit Document or of any Collateral; and the Agent makes no representation of any kind or character with respect to any such matters mentioned in this sentence. The Agent may execute any of its duties under any of the Credit Documents by or through employees, agents, Affiliates, and attorneys-in-fact and shall not be answerable to the Lenders or any other Person for the default or misconduct of any such agents or attorneys-in-fact selected with reasonable care. The Agent shall not incur any liability by acting in reliance upon any notice, consent, certificate, other document or statement (whether written or oral) believed by it to be genuine or to be sent by the proper party or parties. In particular and without limiting any of the foregoing, the Agent shall have no responsibility for confirming the existence or worth of any Collateral or the accuracy of any Compliance Certificate or other document or instrument received by it under the Credit Documents. The Agent may treat the payee of any Note as the holder thereof until written notice of transfer shall have been filed with such Agent signed by such owner in form satisfactory to such Agent. Each Lender acknowledges that it has independently and without reliance on the Agent or any other Lender obtained such information and made such investigations and inquiries regarding the Borrower and its Subsidiaries as it deems appropriate, and based upon such information, investigations and inquiries, made its own credit analysis and decision to extend credit to the Borrower in the manner set forth in the Credit Documents. It shall be the responsibility of each Lender to keep itself informed about the creditworthiness and business, properties, assets, liabilities, condition (financial or otherwise) and prospects of the Borrower and its Subsidiaries, the creditworthiness of all account debtors of the Borrower and its Subsidiaries, and the Agent shall have no liability whatsoever to any Lender for such matters. The Agent shall have no duty to disclose to the Lenders information that is not required by any Credit Document to be furnished by the Borrower or any Subsidiaries to such Agent at such time, but is voluntarily furnished to such Agent (either in its respective capacity as Agent or in its individual capacity). Section 9.6 Indemnity. The Lenders shall ratably, in accordance with their Percentages, indemnify and hold the Agent and its directors, officers, employees, agents and representatives harmless from and against any liabilities, losses, costs or expenses suffered or incurred by it or by any security trustee under any Credit Document or in connection with the transactions contemplated thereby, regardless of when asserted or arising, except to the extent they are promptly reimbursed for the same by the Borrower or out of the proceeds of any Collateral and except to the extent that any event giving rise to a claim was caused by the gross negligence or willful misconduct of the party seeking to be indemnified. The obligations of the Lenders under this SECTION 9.6 shall survive termination of this Agreement. Section 9.7 Resignation of Agent and Successor Agent. The Agent may resign at any time upon at least thirty (30) days' prior written notice to the Lenders and the Borrower. Upon any such resignation of the Agent, the Majority Lenders, with the consent of the Borrower, which consent shall not be unreasonably withheld, shall have the right to appoint a successor Agent. If no successor Agent shall have been so appointed by the Majority Lenders and shall have accepted such appointment within thirty (30) days after the retiring Agent's giving of notice of resignation, then the retiring Agent, may, on behalf of the Lenders, appoint a successor Agent 52 which shall be any Lender hereunder or any commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $250,000,000. Upon the acceptance of its appointment as the Agent hereunder, such successor Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring Agent under the Credit Documents, and the retiring Agent shall be discharged from its duties and obligations thereunder. After any retiring Agent's resignation hereunder as Agent, the provisions of this SECTION 9 and all protective provisions of the other Credit Documents shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent. SECTION 10. MISCELLANEOUS. Section 10.1 No Waiver of Rights. No delay or failure on the part of the Agent or any of the Lenders, or on the part of the holder or holders of the Notes, in the exercise of any power, right or remedy under any Credit Document shall operate as a waiver thereof or as an acquiescence in any default, nor shall any single or partial exercise thereof preclude any other or further exercise of any other power, right or remedy. To the fullest extent permitted by applicable law, the powers, rights and remedies under the Credit Documents of the Lenders and the holder or holders of the Notes are cumulative to, and not exclusive of, any rights or remedies any of them would otherwise have. Section 10.2 Non-Business Day. Subject to SECTION 2.5(b), if any payment of principal or interest on any Loan, Reimbursement Obligation or of any other Obligation shall fall due on a day which is not a Business Day, interest or fees (as applicable) at the rate, if any, for such Loan, such Reimbursement Obligation or such other Obligation bears for the period prior to maturity shall continue to accrue in the manner set forth herein on such Obligation from the stated due date thereof to and including the next succeeding Business Day on which the same shall be payable. Section 10.3 Documentary Taxes. The Borrower agrees that it will pay any documentary, stamp or similar taxes payable with respect to any Credit Document, including interest and penalties, in the event any such taxes are assessed irrespective of when such assessment is made and regardless whether any credit is then in use or available hereunder. Section 10.4 Survival of Representations. All representations and warranties made herein or in certificates given pursuant hereto shall survive the execution and delivery of this Agreement and the other Credit Documents, and shall continue in full force and effect with respect to the date as of which they were made as long as the Borrower has any Obligation hereunder or any L/C Commitment hereunder is in effect. Section 10.5 Survival of Indemnities. All indemnities and all other provisions relative to reimbursement to the Agent and the Lenders of amounts sufficient to protect the yield of the Lenders or the Agent with respect to the Loans shall survive the termination of this Agreement and the other Credit Documents and the payment of the Loans and all other Obligations, as applicable, for a period of one (1) year. Section 10.6 Setoff. In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, upon the occurrence of, and throughout the continuance of, any Default or Event of Default, the Agent and each of the Lenders and each 53 subsequent holder of any of the Notes is hereby authorized by the Borrower at any time or from time to time, without notice to the Borrower, to any Subsidiary of the Borrower or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, Indebtedness evidenced by certificates of deposit, whether matured or unmatured, but not including trust accounts, and in whatever currency denominated) and any other Indebtedness at any time held or owing by the Agent or the Lenders or that subsequent holder to or for the credit or the account of the Borrower, whether or not matured, against and on account of the obligations and liabilities of the Borrower to the Agent or the Lenders or that subsequent holder under the Credit Documents, including, but not limited to, all claims of any nature or description arising out of or connected with the Credit Documents, irrespective of whether or not (i) the Agent or any of the Lenders or that subsequent holder shall have made any demand hereunder or (ii) the principal of or the interest on the Loans, the Notes and other amounts due hereunder shall have become due and payable hereunder and although said obligations and liabilities, or any of them, may be contingent or unmatured. The Agent or such Lender, as applicable, shall promptly give the Borrower notice of any such setoff, provided that any failure to give such notice shall not impact the validity of any such setoff or give rise to any liability of the Agent or any Lender as a result of any such failure. The Agent and the Lenders agree, if there shall be any other Lenders pursuant to SECTION 10.10(b), that if a Lender receives and retains any payment, whether by setoff or application of deposit balances or otherwise, on any of the Loans or L/C Obligations in excess of its ratable share of payments on all such Obligations then owed to the Lenders hereunder, then such Lender shall purchase for cash at face value, but without recourse, ratably from each of the other Lenders such amount of the Loans or L/C Obligations, or participations therein, held by such Lender (or interest therein) as shall be necessary to cause such Lender to share such excess payment ratably with all the other Lenders; provided, however, that if any such purchase is made by any Lender, and if such excess payment or part thereof is thereafter recovered from such purchasing Lender, the related purchases from the other Lenders shall be rescinded ratably and the purchase price restored as to the portion of such excess payment so recovered, with interest pro rata, to the extent the purchasing Lender is required to pay interest on the amount restored.

Telecopies of signatures shall be binding and effective as originals. Section 10.9 Successors and Assigns. This Agreement shall be binding upon the Borrower, the Agent, the Lenders and their respective successors and assigns, and shall inure to the benefit of the Borrower, the Agent, the Lenders and their respective successors and assigns, including any subsequent holder of the Notes. The Borrower may not assign any of its rights or obligations under any Credit Document without the consent of the Agent and all of the Lenders. Section 10.10 Sales and Transfers of Loans and Notes; Participations in Loans and Notes. (a) Any Lender may at any time sell to one or more banks or other financial institutions having a combined capital and surplus of at least $250,000,000 ("PARTICIPANTS"), participating interests in any Loan owing to such Lender, any Note held by such Lender, any L/C Commitment of such Lender or any other interest of such Lender hereunder, provided that no Lender may sell any participating interests in any such Loan, Note, L/C Commitment or other interest hereunder without also selling to such Participant the appropriate pro rata share of its Loans, Notes, L/C Commitments and other interests hereunder, and provided further that no Lender shall transfer, grant or assign any participation under which the Participant shall have rights to vote upon or consent to any matter to be decided by the Lender or the Majority Lenders hereunder or under any Credit Document or approve any amendment to or waiver of this Agreement or any other Credit Document except to the extent such amendment or waiver would (i) increase the amount of such Lender's L/C Commitment and such increase would affect such 55 Participant, (ii) reduce the principal of, or interest on, any of such Lender's Loans, or any fees or other amounts payable to such Lender hereunder and such reduction would affect such Participant, (iii) postpone any date fixed for any scheduled payment of principal of, or interest on, any of such Lender's Loans, or any fees or other amounts payable to such Lender hereunder, or (iv) release any collateral for any Obligation (including, without limitation, any Subsidiary Guaranty), except as otherwise specifically provided in any Credit Document. In the event of any such sale by a Lender of participating interests to a Participant, such Lender's obligations under this Agreement to the other parties to this Agreement shall remain unchanged, such Lender shall remain solely responsible for the performance thereof, such Lender shall remain the holder of any such Note for all purposes under this Agreement and the Borrower and the Agent shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement. The Borrower agrees that if amounts outstanding under this Agreement and the Notes are due and unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall be deemed to have the right of setoff in respect of its participating interest in amounts owing under this Agreement and any Note to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement or any Note, provided that such right of setoff shall be subject to the obligation of such Participant to share with the Lenders, and the Lenders agree to share with such Participant, as provided in SECTION 10.6. The Borrower also agrees that each Participant shall be entitled to the benefits of SECTIONS 2.12 and 8.3 with respect to its participation in the L/C Commitments and the Loans outstanding from time to time, provided that no Participant shall be entitled to receive any greater amount pursuant to such Sections than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred. (b) Any Lender may at any time sell to any Lender or any Affiliate thereof, and, with the consent of the Agent and the Borrower (which shall not be unreasonably withheld or delayed), to one or more banks or other financial institutions having a combined capital and surplus of at least $250,000,000 (a "PURCHASING LENDER"), all or any part of its rights and obligations under this Agreement and the Notes, pursuant to an Assignment Agreement in the form attached as EXHIBIT 10.10 hereto, executed by such Purchasing Lender and such transferor Lender (and, in the case of a Purchasing Lender which is not then a Lender or an Affiliate thereof, by the Borrower and the Agent) and delivered to the Agent; provided that, (i) each such sale to a Purchasing Lender is for an identical percentage of the transferor Lender's rights and obligations under the Term Loan and the L/C Commitment, and (ii) each such sale to a Purchasing Lender shall be in an amount of $5,000,000 or more, or if in a lesser amount, such sale shall be of all of the Lender's rights and obligations under this Agreement and all of the Notes payable to it to one eligible assignee. Notwithstanding the above, any Lender may sell to one or more eligible assignees all or any part of their rights and obligations under this Agreement and the Notes with only the consent of the Agent (which shall not be unreasonably withheld) if an Event of Default shall have occurred and be continuing. No Lender may sell any Loans to a Purchasing Lender without also selling to such Purchasing Lender the appropriate pro rata share of its Notes, L/C Commitments and other interests hereunder, including participations in Letters of Credit hereunder. Upon such execution, delivery, acceptance and recording, from and after the effective date of the transfer determined pursuant to such Assignment Agreement (x) the Purchasing Lender thereunder shall be a party hereto and, to the extent provided in such Assignment Agreement, have the rights and obligations of a Lender hereunder with an L/C Commitment as set forth therein and (y) the transferor Lender thereunder shall, to the extent 56 provided in such Assignment Agreement, be released from its obligations under this Agreement (and, in the case of an Assignment Agreement covering all or the remaining portion of a transferor Lender's rights and obligations under this Agreement, such transferor Lender shall cease to be a party hereto). Such Assignment Agreement shall be deemed to amend this Agreement to the extent, and only to the extent, necessary to reflect the addition of such Purchasing Lender and the resulting adjustment of L/C Commitments and Percentages arising from the purchase by such Purchasing Lender of all or a portion of the rights and obligations of such transferor Lender under this Agreement, the Notes and the other Credit Documents. On or prior to the effective date of the transfer determined pursuant to such Assignment Agreement, the Borrower, at its own expense, shall execute and deliver to the Agent in exchange for any surrendered Notes, new Notes as appropriate to the order of such Purchasing Lender in an amount equal to the Loans assumed by it pursuant to such Assignment Agreement, and, if the transferor Lender has retained a Loan hereunder, new Notes to the order of the transferor Lender in an amount equal to the Loans retained by it hereunder. Such new Notes shall be dated the Initial Borrowing Date and shall otherwise be in the form of the Notes replaced thereby. The Notes surrendered by the transferor Lender shall be returned by the Agent to the Borrower marked "cancelled." (c) Upon its receipt of an Assignment Agreement executed by a transferor Lender, a Purchasing Lender and the Agent (and, in the case of a Purchasing Lender that is not then a Lender or an Affiliate thereof, by the Borrower), together with payment to the Agent hereunder of a registration and processing fee of $3,500, the Agent shall (i) promptly accept such Assignment Agreement, and (ii) on the effective date of the transfer determined pursuant thereto give notice of such acceptance and recordation to the Lenders and the Borrower. (d) The provisions of the foregoing clauses (b) and (c) shall not apply to or restrict, or require the consent of or any notice to any Person to effectuate, the pledge or assignment by any Lender of its rights under this Agreement and its Notes to any Federal Reserve Bank. (e) If, pursuant to this SECTION 10.10 any interest in this Agreement or any Note is transferred to any transferee which is organized under the laws of any jurisdiction other than the United States of America or any State thereof, the transferor Lender shall cause such transferee, concurrently with the effectiveness of such transfer, (i) to represent to the transferor Lender (for the benefit of the transferor Lender, the Agent and the Borrower) that under applicable law and treaties no taxes will be required to be withheld by the Agent, the Borrower or the transferor Lender with respect to any payments to be made to such transferee in respect of the Loans or the L/C Obligations, (ii) to furnish to the transferor Lender (and, in the case of any Purchasing Lender, the Agent and the Borrower) either U.S. Internal Revenue Service Form 4224 or U.S. Internal Revenue Service Form 1001 or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities (wherein such transferee claims entitlement to complete exemption from U.S. federal withholding tax on all interest payments hereunder), and (iii) to agree (for the benefit of the transferor Lender, the Agent and the Borrower) to provide the transferor Lender (and, in the case of any Purchasing Lender, the Agent and the Borrower) a new Form 4224 or Form 1001, or any successor forms thereto, upon the expiration or obsolescence of any previously delivered form and comparable statements in accordance with applicable U.S. laws and regulations and amendments dully executed and completed by such 57 transferee, and to comply from time to time with all applicable U.S. laws and regulations with regard to such withholding tax exemption. Section 10.11 Amendments. Any provision of the Credit Documents may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by (a) the Borrower, (b) the Majority Lenders (in the case of a consent or waiver, the Borrower may rely on the consent or waiver of the Agent on behalf of the Majority Lenders, the Agent agreeing to obtain the necessary consents or waivers from the Majority Lenders before providing such consent or waiver), and (c) if the rights or duties of the Agent are affected thereby, the Agent; provided that: (i) no amendment or waiver shall (A) increase the L/C Commitment Amount without the consent of all Lenders or increase any L/C Commitment of any Lender without the consent of such Lender, (B) postpone the Maturity Date without the consent of all Lenders or reduce the amount of or postpone the date for any scheduled payment of any principal of or interest on any Loan, Reimbursement Obligation or of any fee or any other amounts payable hereunder without the consent of each Lender owed such Obligation or (C) release any Subsidiary Guaranty or any Collateral without the consent of all the Lenders and the Agent; and (ii) no amendment or waiver shall, unless signed by each Lender, change the provisions of this SECTION 10.11 or the definition of Majority Lenders or affect the number of Lenders required to take any action under any other provision of the Credit Documents. Section 10.12 Headings. Section headings used in this Agreement are for reference only and shall not affect the construction of this Agreement. Section 10.13 Legal Fees, Other Costs and Indemnification. The Borrower, upon demand by the Agent or any Lender, agrees to pay the reasonable fees and disbursements of legal counsel and financial advisors to the Agent or any Lender in connection with (a) the preparation and execution of the Credit Documents, any amendment, waiver or consent related thereto, whether or not the transactions contemplated therein are consummated, (b) any Default or Event of Default by the Borrower hereunder and any enforcement (including, without limitation, all workout and bankruptcy proceedings) of any of the Credit Documents or collection of any Obligations, and (c) any refinancings, restructures or "work out" of the transactions contemplated by the Credit Documents; provided that the Borrower shall only have to pay the reasonable fees and disbursements of one law firm and one financial advisory firm in connection therewith unless the Agent, any Lender or their counsel is of the reasonable opinion that representation by one law firm or one financial advisory firm, as applicable, would not be feasible or that a conflict of interest would exist. The Borrower further agrees to indemnify the Agent and each Lender and its respective directors, officers, shareholders, employees and attorneys (collectively, the "INDEMNIFIED PARTIES"), against all losses, claims, damages, penalties, judgments, liabilities and expenses (including, without limitation, all reasonable attorneys' fees and other reasonable expenses of litigation or preparation therefor, whether or not the Indemnified Party is a party thereto) which any of them may pay or incur arising out of or relating to (a) any Credit Document, the Loans, the Letters of Credit or the application or proposed application by the Borrower of the proceeds of any Loan, REGARDLESS OF 58 WHETHER SUCH CLAIMS OR ACTIONS ARE FOUNDED IN WHOLE OR IN PART UPON THE ALLEGED SIMPLE OR CONTRIBUTORY NEGLIGENCE OF ANY OF THE INDEMNIFIED PARTIES AND/OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS, SHAREHOLDERS, EMPLOYEES OR ATTORNEYS, (b) any investigation of any third party or any governmental authority involving the Agent or any Lender and related to any use made or proposed to be made by the Borrower of the proceeds of the Loans, or any transaction financed or to be financed in whole or in part, directly or indirectly with the proceeds of any Loan, and (c) any investigation of any third party or any governmental authority, litigation or proceeding, related to any environmental cleanup, audit, compliance or other matter relating to any Environmental Law or the presence of any Hazardous Material (including, without limitation, any losses, liabilities, damages, injuries, costs, expenses or claims asserted or arising under any Environmental Law) with respect to the Borrower or any of its Subsidiaries, regardless of whether caused by, or within the control of, the Borrower or any of its Subsidiaries; provided, however, that the Borrower shall not be obligated to indemnify any Indemnified Party for any of the foregoing arising out of (i) such Indemnified Party's gross negligence or willful misconduct, (ii) the Agent's failure to pay under any Letter of Credit after the presentation to it of a request required to be paid under applicable law, (iii) the Agent's or any Lender's breach of any material provision of any Credit Document, or any dispute solely among the Agent and the Lenders or any of same. The Borrower, upon demand by the Indemnified Party at any time, shall reimburse the Indemnified Party for any legal or other expenses incurred in connection with investigating or defending against any of the foregoing except if the same is excluded from indemnification pursuant to the provisions of the foregoing sentence. Section 10.14 Governing Law; Submission to Jurisdiction; Waiver of Jury Trial. (a) The Credit Agreement, and the other Credit Documents, and the rights and duties of the parties thereto, shall be construed in accordance with and governed by the internal laws of the State of Texas. (b) THE AGENT, EACH LENDER AND THE BORROWER HEREBY WAIVES ITS RIGHT TO RESOLVE DISPUTES, CLAIMS, AND CONTROVERSIES ARISING FROM THE CREDIT AGREEMENT, ANY OTHER CREDIT DOCUMENT OR ANY MATTER IN CONNECTION THEREWITH, INCLUDING, WITHOUT LIMITATION, CONTRACT DISPUTES AND TORT CLAIMS, THROUGH ANY COURT PROCEEDING OR LITIGATION AND ACKNOWLEDGES THAT ALL SUCH DISPUTES, CLAIMS AND CONTROVERSIES SHALL BE RESOLVED PURSUANT TO THIS SECTION, EXCEPT THAT EQUITABLE RELIEF AND CERTAIN OTHER RIGHTS AND REMEDIES SET FORTH BELOW MAY BE SOUGHT FROM ANY COURT OF COMPETENT JURISDICTION. EACH PARTY REPRESENTS TO THE OTHER PARTIES THAT THIS WAIVER IS MADE KNOWINGLY AND VOLUNTARILY AFTER CONSULTATION WITH AND UPON ADVICE OF ITS COUNSEL AND IS A MATERIAL PART OF THIS AGREEMENT. ALL SUCH DISPUTES, CLAIMS AND CONTROVERSIES SHALL BE RESOLVED BY BINDING ARBITRATION PURSUANT TO THE COMMERCIAL RULES OF THE AMERICAN ARBITRATION ASSOCIATION ("AAA"). Any arbitration proceeding held pursuant to this arbitration provision shall be conducted in Houston, Texas or at any other place selected by mutual agreement of the parties. No act to take or dispose of any collateral shall constitute a waiver of this arbitration agreement or be prohibited by this arbitration agreement. This 59 arbitration provision shall not limit the right of any party during any dispute, claim or controversy to seek, use, and employ ancillary, or preliminary rights and/or remedies, judicial or otherwise, for the purposes of realizing upon, preserving, protecting, foreclosing upon or proceeding under forcible entry and detainer for possession of, any real or personal property, and any such action shall not be deemed an election of remedies. Such remedies include, without limitation, obtaining injunctive relief or a temporary restraining order, invoking a power of sale under any deed of trust or mortgage, obtaining a writ of attachment or imposition of a receivership, or exercising any rights relating to personal property, including exercising the right of set-off, or taking or disposing of such property with or without judicial process pursuant to the Uniform Commercial Code.

Judgment upon any award rendered by any arbitrator may be entered in any court having jurisdiction. The statute of limitations, estoppel, waiver, laches and similar doctrines which would otherwise be applicable in an action brought by a party shall be applicable in any arbitration proceeding, and the commencement of an arbitration proceeding shall be deemed the commencement of any action for these purposes. The federal arbitration act (Title 9 of the United States Code) shall apply to the construction, interpretation, and enforcement of this arbitration provision.

To the fullest extent permitted by applicable law, the Borrower further irrevocably consents to the service of process, by registered mail, postage prepaid, or by personal service within or without the state of Texas. To the fullest extent permitted by applicable law, the Borrower hereby expressly and irrevocably waives any objection which it may have or hereafter may have to the laying of venue of any such litigation brought in any such court referred to above and any claim that any such litigation has been brought in an inconvenient forum. To the extent that the Borrower has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service of notice, attachment prior to judgment, attachment in aid of execution or otherwise) with respect to itself or its property, the Borrower hereby irrevocably waives to the fullest extent permitted by applicable law, such immunity in respect of its obligations under the Credit Agreement and the other Credit Documents. (d) TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EACH PARTY TO THIS AGREEMENT VOLUNTARILY, KNOWINGLY, IRREVOCABLY AND UNCONDITIONALLY (BY ITS ACCEPTANCE OF THIS AGREEMENT) WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING PERMITTED BY SECTION 10.14(B) AND WAIVES ANY RIGHT TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF THE CREDIT 60 AGREEMENT, ANY OTHER CREDIT DOCUMENT, ANY OTHER RELATED DOCUMENT OR ANY RELATIONSHIP BETWEEN THE AGENT, ANY LENDER, THE BORROWER AND/OR ANY GUARANTOR, AND AGREES THAT ANY SUCH ACTION, PROCEEDING OR DISPUTE SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY.

Section 10.17 Change in Accounting Principles or Tax Laws. If (i) any change in accounting principles from those used in the preparation of the financial statements of the Borrower referred to in SECTION 5.9 is hereafter occasioned by the promulgation of rules, regulations, pronouncements and opinions by or required by the Financial Accounting Standards Board or the American Institute of Certified Public Accounts (or successors thereto or agencies with similar functions) and such change materially affects the calculation of any component of any financial covenant, standard or term found in this Agreement, or (ii) there is a material change in federal or foreign tax laws which materially affects the Borrower's ability to comply with the financial covenants, standards or terms found in this Agreement, the Borrower, the Agent and the Lenders agree to enter into negotiations in order to amend such provisions so as to equitably reflect such changes with the desired result that the criteria for evaluating the Borrower's and its Subsidiaries' consolidated financial condition shall be the same after such changes as if such changes had not been made. Unless and until such provisions have been so 61 amended, the provisions of this Agreement shall govern, provided that, for purposes of this SECTION 10.17, the Borrower shall have 90 days from the date of any such change to amend the appropriate provisions of this Agreement to reflect such change in accordance with the immediately preceding sentence.
