TCB or, with the prior approval of Borrower, Agent and the applicable Lender, another Lender shall be the Issuer of each Letter of Credit. (b) ADDITIONAL PROVISIONS. The following additional provisions shall apply to each Letter of Credit: (i) Borrower shall give Agent notice requesting each issuance of a Letter of Credit hereunder as provided in SECTION 4.3 hereof and shall furnish such additional information regarding such transaction as Agent may reasonably request. Upon receipt of such notice, Agent shall promptly notify each Revolving Loan Lender of the contents thereof and of such Lender's Revolving Loan Commitment Percentage of the amount of such proposed Letter of Credit.

To the extent that it is ultimately determined that the Borrower is relieved of its obligation to reimburse the applicable Issuer because of such Issuer's gross negligence or willful misconduct in determining that documents received under any applicable Letter of Credit comply with the terms thereof, the applicable Issuer shall be obligated to refund to the paying Lenders all amounts paid to such Issuer to reimburse Issuer for the applicable drawing under such Letter of Credit. (iv) Borrower shall be irrevocably and unconditionally obligated forthwith to reimburse Agent, on the date on which the Agent notifies Borrower of the date and amount of any payment by the Issuer of any drawing under a Letter of Credit, for the amount paid by any Issuer upon such drawing, without presentment, demand, protest or other formalities of any kind, all of which are hereby waived. Such reimbursement may, subject to satisfaction of the conditions in SECTIONS 5.1 and 5.2 hereof and to the aggregate of the Revolving Loan Commitments (after adjustment in the same to reflect the elimination of the corresponding Letter of Credit Liability), be made by the borrowing of Loans. Agent will pay to each Revolving Loan Lender such Lender's Revolving Loan Commitment Percentage of all amounts received from Borrower for application in payment, in whole or in part, of the Reimbursement Obligation in respect of any Letter of Credit, but only to the extent such Lender has made payment to Agent in respect of such Letter of Credit pursuant to CLAUSE (III) above. (v) Borrower will pay to Agent at the Principal Office for the account of each Revolving Loan Lender a letter of credit fee with respect to each Letter of Credit equal to the greater of (x) $500 or (y) the then current Margin Percentage for LIBOR Borrowings multiplied by the face amount of such Letter of Credit (and computed on the basis of the actual number of days elapsed in a year composed of 360 days), in each case for the period from and including the date of issuance of such Letter of Credit to and including the date of expiration or termination thereof, such fee to be due and payable in advance.

(vi) The issuance by the applicable Issuer of each Letter of Credit shall, in addition to the conditions precedent set forth in SECTION 5 hereof, be subject to the conditions precedent (A) that such Letter of Credit shall be in such form and contain such terms as shall be reasonably satisfactory to Agent, and (B) that Borrower shall have executed and delivered such Applications and other instruments and agreements relating to such Letter of Credit as Agent shall have reasonably requested and are not inconsistent with the terms of this Agreement. In the event of a conflict between the terms of this Agreement and the terms of any Application, the terms hereof shall control. (vii) Issuer will send to the Borrower and each Lender, immediately upon issuance of any Letter of Credit issued by Issuer or any amendment thereto, a true and correct copy of such Letter of Credit or amendment.

Borrower hereby releases, waives and discharges Agent, each Revolving Loan Lender and each Issuer from any claims, causes of action, damages, losses, liabilities, reasonable costs or expenses which may now exist or may hereafter arise, REGARDLESS OF WHETHER CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE OF ANY OF THE INDEMNIFIED PARTIES, by reason of or in connection with the failure of any other Revolving Loan Lender to fulfill or comply with its obligations to Agent, such Lender or such Issuer, as the case may be, hereunder (but nothing herein contained shall affect any rights Borrower may have against such defaulting Lender); PROVIDED that Borrower shall not be required to indemnify any party seeking indemnification for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by (i) the willful misconduct or gross negligence of the party seeking 21 indemnification, or (ii) the failure by the party seeking indemnification to pay under any Letter of Credit after the presentation to it of a request required to be paid under applicable law or (iii) disputes between or among any and all of Agent, Lenders and Issuers.

Such statement as to such increased costs or reductions in amount incurred by such Lender, submitted by such Lender to Borrower, shall create a rebuttable presumption as to the accuracy thereof, and may be computed using any reasonable averaging and attribution method. Each Lender will notify Borrower through Agent of any event occurring after the date of this Agreement which will entitle such Lender to compensation pursuant to this Section as promptly as practicable after any executive officer of such Lender obtains knowledge thereof and determines to request such compensation, and (if so requested by Borrower through Agent) will designate a different lending office of such Lender for the issuance or maintenance of Letters of Credit by such Lender or will take such other action as Borrower may reasonably request if such designation or action is consistent with the internal policy of such Lender and legal and regulatory restrictions, can be undertaken at no additional cost, will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of such Lender, be disadvantageous to such Lender (PROVIDED that such Lender shall have no obligation so to designate a different lending office which is not located in the United States of America). 2.3 TERMINATIONS OR REDUCTIONS OF COMMITMENTS. (a) MANDATORY. On the Revolving Loan Termination Date, all Revolving Loan Commitments shall be terminated in their entirety. (b) OPTIONAL. Borrower shall have the right to terminate or reduce the unused portion of the Revolving Loan Commitments at any time or from time to time, PROVIDED that (i) Borrower shall give notice of each such termination or reduction to Agent as provided in SECTION 4.3 hereof and (ii) each such partial reduction shall be in an integral multiple of $5,000,000. 22 (c) NO REINSTATEMENT. No termination or reduction of the Revolving Loan Commitments may be reinstated without the written approval of Agent and the Lenders. 2.4 COMMITMENT FEES. (a) Borrower shall pay to Agent for the account of each Revolving Loan Lender revolving loan commitment fees for the period from the earlier of the initial Loan hereunder or October 31, 1997 to and including the Revolving Loan Termination Date at a rate per annum equal to the Commitment Fee Percentage. Such revolving loan commitment fees shall be computed (on the basis of the actual number of days elapsed in a year composed of 360 days) on each day and shall be based on the excess of (x) the aggregate amount of each Revolving Loan Lender's Revolving Loan Commitment for such day over (y) the sum of (i) the aggregate unpaid principal balance of such Lender's Revolving Note on such day PLUS (ii) the aggregate Letter of Credit Liabilities as to such Lender for such day. Accrued revolving loan commitment fees shall be payable in arrears on the Quarterly Dates prior to the Revolving Loan Termination Date and on the Revolving Loan Termination Date. (b) All past due fees payable under this Section shall bear interest at the Past Due Rate. 2.5 SEVERAL OBLIGATIONS. The failure of any Lender to make any Loan to be made by it on the date specified therefor shall not relieve any other Lender of its obligation to make its Loan on such date, but neither Agent nor any Lender shall be responsible or liable for the failure of any other Lender to make a Loan to be made by such other Lender or to participate in, or co-issue, any Letter of Credit. Notwithstanding anything contained herein to the contrary, (a) no Lender shall be required to make or maintain Loans at any time outstanding if as a result the total Revolving Loan Obligations held by such Lender shall exceed the lesser of (1) such Lender's Revolving Loan Commitment Percentage of all Revolving Loan Obligations and (2) such Lender's Revolving Loan Commitment Percentage of the aggregate of the Revolving Loan Commitments and (b) if a Revolving Loan Lender fails to make a Loan as and when required hereunder, then upon each subsequent event which would otherwise result in funds being paid to the defaulting Lender, the amount which would have been paid to the defaulting Lender shall be divided among the non-defaulting Lenders ratably according to their respective shares of the outstanding Revolving Loan Commitment Percentages until the Revolving Loan Obligations of each Revolving Loan Lender (including the defaulting Lender) are equal to such Lender's Revolving Loan Commitment Percentage of the total Revolving Loan Obligations. 2.6 NOTES. The Loans made by each Lender shall be evidenced by a single promissory note of Borrower in substantially the form of EXHIBIT C hereto payable to the order of such Lender in a principal amount equal to the Revolving Loan Commitment of such Lender, and otherwise duly completed. The promissory notes described in this Section are each, together with all renewals, extensions, modifications, amendments, increases and/or and replacements thereof and substitutions therefor, called a "NOTE" and collectively called the "NOTES". Each Lender is hereby authorized by Borrower to endorse on the schedule (or a continuation thereof) that may be attached to each Note of such Lender, to the extent applicable, the date, amount, type of and the applicable 23 period of interest for each Loan made by such Lender to Borrower hereunder, and the amount of each payment or prepayment of principal of such Loan received by such Lender, PROVIDED, that any failure by such Lender to make any such endorsement shall not affect the obligations of Borrower under such Note or hereunder in respect of such Loan. 2.7 USE OF PROCEEDS. The proceeds of the Loans shall be used to refinance existing Borrowed Money Indebtedness of Borrower, to finance acquisitions and for other working capital and general corporate purposes. Neither Agent nor any Lender shall have any responsibility as to the use of any proceeds of the Loans. 3. BORROWINGS, PAYMENTS, PREPAYMENTS AND INTEREST OPTIONS. 3.1 BORROWINGS. Borrower shall give Agent notice of each borrowing to be made hereunder as provided in SECTION 4.3 hereof and Agent shall promptly notify each Lender of such request. Not later than 2:00 p.m. Houston time on the date specified for each such borrowing hereunder, each Lender shall make available the amount of the Loan, if any, to be made by it on such date to Agent at its Principal Office, in immediately available funds, for the account of Borrower. Such amounts received by Agent will be held in an account maintained by Borrower with Agent. The amounts so received by Agent shall, subject to the terms and conditions of this Agreement, be made available to Borrower by wiring or otherwise transferring, in immediately available funds, such amount to an account designated by Borrower. 3.2 PREPAYMENTS. (a) OPTIONAL PREPAYMENTS. Except as provided in SECTION 3.3 hereof, Borrower shall have the right to prepay, on any Business Day, in whole or in part, without the payment of any penalty or fee, any Loans at any time or from time to time, PROVIDED that Borrower shall give Agent notice of each such prepayment as provided in SECTION 4.3 hereof. Each optional prepayment on a Loan shall be in an amount equal to an integral multiple of $250,000. (b) INTEREST PAYMENTS. Accrued and unpaid interest on the unpaid principal balance of the Loans shall be due and payable on the Interest Payment Dates. (c) PAYMENTS AND INTEREST ON REIMBURSEMENT OBLIGATIONS. Borrower will pay to Agent for the account of each Lender the amount of each Reimbursement Obligation on the date on which the Agent notifies Borrower of the date and amount of the applicable payment by the Issuer of any drawing under a Letter of Credit. The amount of any Reimbursement Obligation may, if the applicable conditions precedent specified in SECTIONS 5.1 and 5.2 hereof have been satisfied, be paid with the proceeds of Loans. Subject to SECTION 11.7 hereof, Borrower will pay to Agent for the account of each Lender interest on any Reimbursement Obligation (i) at the Base Rate plus the applicable Margin Percentage from the date such Reimbursement Obligation arises until the date five (5) Business Days thereafter and (ii) at the Past Due Rate thereafter until the same is paid in full. 24 3.3 INTEREST OPTIONS (a) OPTIONS AVAILABLE. The outstanding principal balance of the Notes shall bear interest at the Base Rate; PROVIDED, that (1) all past due amounts, both principal and accrued interest, shall bear interest at the Past Due Rate, and (2) subject to the provisions hereof, Borrower shall have the option of having all or any portion of the principal balances of the Notes from time to time outstanding bear interest at a Eurodollar Rate. The records of Agent and each of the Lenders with respect to Interest Options, Interest Periods and the amounts of Loans to which they are applicable shall create a rebuttable presumption as to the accuracy thereof, and Agent and Lenders agree to furnish written evidence to Borrower upon request of Borrower with respect to such matters. Interest on the Loans shall be calculated at the Base Rate except where it is expressly provided pursuant to this Agreement that a Eurodollar Rate is to apply. Interest on the amount of each advance against the Notes shall be computed on the amount of that advance and from the date it is made. Notwithstanding anything in this Agreement to the contrary, for the full term of the Notes the interest rate produced by the aggregate of all sums paid or agreed to be paid to the holders of the Notes for the use, forbearance or detention of the debt evidenced thereby (including all interest on the Notes at the Stated Rate plus the Additional Interest) shall not exceed the Ceiling Rate. (b) DESIGNATION AND CONVERSION. Borrower shall have the right to designate or convert its Interest Options in accordance with the provisions hereof. PROVIDED no Event of Default has occurred and is continuing and subject to the last sentence of SECTION 3.3(A) and the provisions of SECTION 3.3(C), Borrower may elect to have a Eurodollar Rate apply or continue to apply to all or any portion of the principal balance of the Notes. Each change in Interest Options shall be a conversion of the rate of interest applicable to the specified portion of the Loans, but such conversion shall not change the respective outstanding principal balances of the Notes. The Interest Options shall be designated or converted in the manner provided below: (i) Borrower shall give Agent telephonic notice, promptly confirmed by a Rate Designation Notice (and Agent shall promptly inform each Lender thereof). Each such telephonic and written notice shall specify the amount of the Loan which is the subject of the designation, if any; the amount of borrowings into which such borrowings are to be converted or for which an Interest Option is designated; the proposed date for the designation or conversion and the Interest Period or Periods, if any, selected by Borrower. Such telephonic notice shall be irrevocable and shall be given to Agent no later than the applicable Rate Designation Date. (ii) No more than eight (8) LIBOR Borrowings shall be in effect with respect to the Loans at any time. (iii) Each designation or conversion of a LIBOR Borrowing shall occur on a LIBOR Business Day. 25 (iv) Each request for a LIBOR Borrowing shall be in the amount equal to an integral multiple of $250,000. (v) Each designation of an Interest Option with respect to the Revolving Notes shall apply to all of the Revolving Notes ratably in accordance with their respective outstanding principal balances. If any Lender assigns an interest in any of its Notes when any LIBOR Borrowing is outstanding with respect thereto, then such assignee shall have its ratable interest in such LIBOR Borrowing. (c) SPECIAL PROVISIONS APPLICABLE TO LIBOR BORROWINGS. (i) OPTIONS UNLAWFUL. If the adoption of any applicable Legal Requirement after the Effective Date or any change after the Effective Date in any applicable Legal Requirement or in the interpretation or administration thereof by any Governmental Authority or compliance by any Lender with any request or directive (whether or not having the force of law) issued after the Effective Date by any central bank or other Governmental Authority shall at any time make it unlawful or impossible for any Lender to permit the establishment of or to maintain any LIBOR Borrowing, the commitment of such Lender to establish or maintain such LIBOR Borrowing shall forthwith be canceled and Borrower shall forthwith, upon demand by Agent to Borrower, (1) convert the LIBOR Borrowing of such Lender with respect to which such demand was made to a Base Rate Borrowing; (2) pay all accrued and unpaid interest to date on the amount so converted; and (3) pay any amounts required to compensate each Lender for any additional cost or expense which any Lender may incur as a result of such adoption of or change in such Legal Requirement or in the interpretation or administration thereof and any Funding Loss which any Lender may incur as a result of such conversion. If, when Agent so notifies Borrower, Borrower has given a Rate Designation Notice specifying a LIBOR Borrowing but the selected Interest Period has not yet begun, as to the applicable Lender such Rate Designation Notice shall be deemed to be of no force and effect, as if never made, and the balance of the Loans made by such Lender specified in such Rate Designation Notice shall bear interest at the Base Rate until a different available Interest Option shall be designated in accordance herewith. (ii) INCREASED COST OF BORROWINGS. If the adoption after the Effective Date of any applicable Legal Requirement or any change after the Effective Date in any applicable Legal Requirement or in the interpretation or administration thereof by any Governmental Authority or compliance by any Lender with any request or directive (whether or not having the force of law) issued after the Effective Date by any central bank or Governmental Authority shall at any time as a result of any portion of the principal balances of the Notes being maintained on the basis of a Eurodollar Rate: (1) subject any Lender to any Taxes, or any deduction or withholding for any Taxes, on or from any payment due under any LIBOR Borrowing or other amount due hereunder, other than income and franchise taxes of the United States or its political subdivisions or such other jurisdiction in which the applicable Lender has its principal office or applicable lending office; or 26 (2) change the basis of taxation of payments due from Borrower to any Lender under any LIBOR Borrowing (other than by a change in the rate of taxation of the overall net income of such Lender); or (3) impose, modify, increase or deem applicable any reserve requirement (excluding that portion of any reserve requirement included in the calculation of the applicable Eurodollar Rate), special deposit requirement or similar requirement (including, but not limited to, state law requirements and Regulation D) against assets of any Lender, or against deposits with any Lender, or against loans made by any Lender, or against any other funds, obligations or other property owned or held by any Lender; or (4) impose on any Lender any other condition regarding any LIBOR Borrowing; and the result of any of the foregoing is to increase the cost to any Lender of agreeing to make or of making, renewing or maintaining such LIBOR Borrowing, or reduce the amount of principal or interest received by any Lender, then, within 15 Business Days after demand by the applicable Lender (accompanied by a statement setting forth in reasonable detail the applicable Lender's basis therefor), Borrower shall pay to Agent additional amounts which shall compensate each Lender for such increased cost or reduced amount. The determination by any Lender of the amount of any such increased cost, increased reserve requirement or reduced amount shall create a rebuttable presumption as to the accuracy thereof. Borrower shall have the right, if it receives from Agent any notice referred to in this paragraph, upon three Business Days' notice to Agent (which shall notify each affected Lender), either (i) to repay in full (but not in part) any borrowing with respect to which such notice was given, together with any accrued interest thereon, or (ii) to convert the LIBOR Borrowing which is the subject of the notice to a Base Rate Borrowing; PROVIDED, that any such repayment or conversion shall be accompanied by payment of (x) the amount required to compensate each Lender for the increased cost or reduced amount referred to in the preceding paragraph; (y) all accrued and unpaid interest to date on the amount so repaid or converted, and (z) any Funding Loss which any Lender may incur as a result of such repayment or conversion. Each Lender will notify Borrower through Agent of any event occurring after the date of this Agreement which will entitle such Lender to compensation pursuant to this Section as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, and (if so requested by Borrower through Agent) will designate a different lending office of such Lender for the applicable LIBOR Borrowing or will take such other action as Borrower may reasonably request if such designation or action is consistent with the internal policy of such Lender and legal and regulatory restrictions, will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of such Lender, be disadvantageous to such Lender (PROVIDED that such Lender shall have no obligation so to designate a different lending office which is located in the United States of America). (iii) INADEQUACY OF PRICING AND RATE DETERMINATION. If, for any reason with respect to any Interest Period, Agent (or, in the case of CLAUSE 3 below, the applicable Lender) shall have 27 determined (which determination shall create a rebuttable presumption as to the accuracy thereof) that: (1) Agent is unable through its customary general practices to determine any applicable Eurodollar Rate, or (2) by reason of circumstances affecting the applicable market, generally, Agent is not being offered deposits in United States dollars in such market, for the applicable Interest Period and in an amount equal to the amount of any applicable LIBOR Borrowing requested by Borrower, or (3) any applicable Eurodollar Rate will not adequately and fairly reflect the cost to any Lender of making and maintaining such LIBOR Borrowing hereunder for any proposed Interest Period, then Agent shall give Borrower written notice thereof (accompanied by a statement setting forth in reasonable detail the applicable Lender's basis therefor) and thereupon, (A) any Rate Designation Notice previously given by Borrower designating the applicable LIBOR Borrowing which has not commenced as of the date of such notice from Agent shall be deemed for all purposes hereof to be of no force and effect, as if never given, and (B) until Agent shall notify Borrower that the circumstances giving rise to such notice from Agent no longer exist, each Rate Designation Notice requesting the applicable Eurodollar Rate shall be deemed a request for a Base Rate Borrowing, and any applicable LIBOR Borrowing then outstanding shall be converted, without any notice to or from Borrower, upon the termination of the Interest Period then in effect with respect to it, to a Base Rate Borrowing. (iv) FUNDING LOSSES. Borrower shall indemnify each Lender against and hold each Lender harmless from any Funding Loss. This indemnity shall survive the payment of the Notes. A certificate of such Lender (explaining in reasonable detail the amount and calculation of the amount claimed) as to any additional amounts payable pursuant to this paragraph submitted to Borrower shall create a rebuttable presumption as to the accuracy thereof. (d) FUNDING OFFICES; ADJUSTMENTS AUTOMATIC; CALCULATION YEAR. Any Lender may, if it so elects, fulfill its obligation as to any LIBOR Borrowing by causing a branch or affiliate of such Lender to make such Loan and may transfer and carry such Loan at, to or for the account of any branch office or affiliate of such Lender; PROVIDED, that in such event for the purposes of this Agreement such Loan shall be deemed to have been made by such Lender and the obligation of Borrower to repay such Loan shall nevertheless be to such Lender and shall be deemed held by it for the account of such branch or affiliate. Without notice to Borrower or any other Person, each rate required to be calculated or determined under this Agreement shall automatically fluctuate upward and downward in accordance with the provisions of this Agreement. Interest at the Prime Rate shall be computed on the basis of the actual number of days elapsed in a year consisting of 365 or 366 days, as the case may be. All other interest required to be calculated or determined under this Agreement shall be computed on the basis of the actual number of days 28 elapsed in a year consisting of 360 days, unless the Ceiling Rate would thereby be exceeded, in which event, to the extent necessary to avoid exceeding the Ceiling Rate, the applicable interest shall be computed on the basis of the actual number of days elapsed in the applicable calendar year in which accrued. (e) FUNDING SOURCES. Notwithstanding any provision of this Agreement to the contrary, each Lender shall be entitled to fund and maintain its funding of all or any part of the 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 Borrowing during each Interest Period through the purchase of deposits having a maturity corresponding to such Interest Period and bearing an interest rate equal to the Eurodollar Rate for such Interest Period. 3.4 CAPITAL ADEQUACY. If any Lender shall have determined that the adoption after the Effective Date or effectiveness after the Effective Date (whether or not previously announced) of any applicable law, rule, regulation or treaty regarding capital adequacy, or any change therein after the Effective Date, or any change in the interpretation or administration thereof after the Effective Date by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender with any request or directive after the Effective Date regarding capital adequacy (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency has or would have the effect of reducing the rate of return on such Lender's capital as a consequence of its obligations hereunder, under the Letters of Credit, the Notes or other Obligations held by it 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, upon satisfaction of the conditions precedent set forth in this Section, after demand by such Lender (with a copy to Agent) as provided below, Borrower shall pay (subject to SECTION 11.7 hereof) to such Lender such additional amount or amounts as will compensate such Lender for such reduction. The certificate of any Lender setting forth such amount or amounts as shall be necessary to compensate it and the basis thereof and reasons therefor shall be delivered as soon as practicable to Borrower and shall create a rebuttable presumption as to the accuracy thereof. Borrower shall pay the amount shown as due on any such certificate within five (5) Business Days after the delivery of such certificate. In preparing such certificate, a Lender may employ such assumptions and allocations of costs and expenses as it shall in good faith deem reasonable and may use any reasonable averaging and attribution method. 3.5 LIMITATION ON CHARGES; SUBSTITUTE LENDERS; NON-DISCRIMINATION. Anything in SECTIONS 3.3(C) or 3.4 notwithstanding: (1) Borrower shall not be required to pay to any Lender reimbursement with regard to any costs or expenses described in such Sections, unless such Lender notifies Borrower of such costs or expenses within 90 days after the date paid or incurred; 29 (2) none of the Lenders shall be permitted to pass through to Borrower charges and costs under such Sections on a discriminatory basis (i.e., which are not also passed through by such Lender to other customers of such Lender similarly situated where such customer is subject to documents providing for such pass through); and (3) if any Lender elects to pass through to Borrower any material charge or cost under such Sections or elects to terminate the availability of LIBOR Borrowings for any material period of time, Borrower may, within 60 days after the date of such event and so long as no Default shall have occurred and be continuing, elect to terminate such Lender as a party to this Agreement; PROVIDED that, concurrently with such termination Borrower shall (i) if Agent and each of the other Lenders shall consent, pay that Lender all principal, interest and fees and other amounts owed to such Lender through such date of termination or (ii) have arranged for another financial institution approved by Agent (such approval not to be unreasonably withheld) as of such date, to become a substitute Lender for all purposes under this Agreement in the manner provided in SECTION 11.6; PROVIDED FURTHER that, prior to substitution for any Lender, Borrower shall have given written notice to Agent of such intention and the Lenders shall have the option, but no obligation, for a period of 60 days after receipt of such notice, to increase their Revolving Loan Commitments in order to replace the affected Lender in lieu of such substitution. 4. PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS, ETC. 4.1 PAYMENTS. (a) Except to the extent otherwise provided herein, all payments of principal, interest, Reimbursement Obligations and other amounts to be made by Borrower hereunder, under the Notes and under the other Loan Documents shall be made in Dollars, in immediately available funds, to Agent at the Principal Office (or in the case of a successor Agent, at the principal office of such successor Agent in the United States), not later than 11:00 a.m. Houston time on the date on which such payment shall become due (each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day). (b) Borrower shall, at the time of making each payment hereunder, under any Note or under any other Loan Document, specify to Agent the Loans or other amounts payable by Borrower hereunder or thereunder to which such payment is to be applied. Each payment received by Agent hereunder, under any Note or under any other Loan Document for the account of a Lender shall be paid promptly to such Lender, in immediately available funds. If Agent fails to send to any Lender the applicable amount by the close of business on the date any such payment is received by Agent if such payment is received prior to 11:00 a.m. Houston time (or on the next succeeding Business Day with respect to payments which are received after 11:00 a.m. Houston time), Agent shall pay to the applicable Lender interest on such amount from such date at the Federal Funds Rate. Borrower, the Lenders and Agent acknowledge and agree that this provision and each other provision of this Agreement or any of the other Loan Documents relating to the application of amounts in payment of the Obligations shall be subject to the provisions of SECTION 30 4.2(D) regarding PRO RATA application of amounts after an Event of Default shall have occurred and be continuing. (c) If the due date of any payment hereunder or under any Note falls on a day which is not a Business Day, the due date for such payments (except as otherwise provided in SECTION 3.3 hereof) shall be extended to the next succeeding Business Day and interest shall be payable for any principal so extended for the period of such extension. (d) All payments by the Borrower hereunder or under any other Loan Document shall be made free and clear of and without deduction for or on account of any present or future income, stamp, or other taxes, fees, duties, withholding or other charges of any nature whatsoever imposed by any taxing authority excluding in the case of each Lender taxes imposed on or measured by its net income or franchise taxes imposed by the jurisdiction in which it is organized or through which it acts for purposes of this Agreement (such non-excluded items being hereinafter referred to as "TAXES"). If as a result of any change in law (or the interpretation thereof) after the date that the applicable Lender became a "Lender" under this Agreement any withholding or deduction from any payment to be made to, or for the account of, a Lender by the Borrower hereunder or under any other Loan Document is required in respect of any Taxes pursuant to any applicable law, rule, or regulation, then the Borrower will (i) pay to the relevant authority the full amount required to be so withheld or deducted; (ii) to the extent available, promptly forward to the Agent an official receipt or other documentation reasonably satisfactory to the Agent evidencing such payment to such authority; and (iii) pay to the Agent, for the account of each affected Lender, such additional amount or amounts as are necessary to ensure that the net amount actually received by such Lender will equal the full amount such Lender would have received had no such withholding or deduction been required. Each Lender shall determine such additional amount or amounts payable to it (which determination shall create a rebuttable presumption as to the accuracy thereof), and in such event, Agent shall furnish written evidence to Borrower showing how Agent made such determination. If a Lender becomes aware that any such withholding or deduction from any payment to be made by the Borrower hereunder or under any other Loan Document is required, then such Lender shall promptly notify the Agent and the Borrower thereof stating the reasons therefor and the additional amount required to be paid under this Section. Each Lender shall execute and deliver to the Agent and Borrower such forms as it may be required to execute and deliver pursuant to SECTION 11.13 hereof. To the extent that any such withholding or deduction results from the failure of a Lender to provide a form required by SECTION 11.13 hereof (unless such failure is due to some prohibition under applicable Legal Requirements), the Borrower shall have no obligation to pay the additional amount required by CLAUSE (III) above. Anything in this Section notwithstanding, if any Lender elects to require payment by the Borrower of any material amount under this Section, the Borrower may, within 60 days after the date of receiving notice thereof and so long as no Default shall have occurred and be continuing, elect to terminate such Lender as a party to this Agreement; PROVIDED that, concurrently with such termination the Borrower shall (i) if the Agent and each of the other Lenders shall consent, pay that Lender all principal, interest and fees and other amounts owed to such Lender through such date of termination or (ii) have arranged for another financial institution approved by the Agent (such approval not to be unreasonably withheld) as of such date, to become a substitute Lender for all 31 purposes under this Agreement in the manner provided in SECTION 11.6; PROVIDED FURTHER that, prior to substitution for any Lender, the Borrower shall have given written notice to the Agent of such intention and the Lenders shall have the option, but no obligation, for a period of 60 days after receipt of such notice, to increase their Commitments in order to replace the affected Lender in lieu of such substitution. 4.2 PRO RATA TREATMENT. Except to the extent otherwise provided herein: (a) each borrowing from the Lenders under SECTION 2.1 hereof shall be made ratably from the Revolving Loan Lenders in accordance with their respective Revolving Loan Commitments; (b) each payment of revolving loan commitment fees shall be made for the account of the Revolving Loan Lenders, and each termination or reduction of the Revolving Loan Commitments of the Revolving Loan Lenders under SECTION 2.3 hereof shall be applied, PRO RATA, according to the Revolving Loan Lenders' respective Revolving Loan Commitments; (c) each payment by Borrower of principal of or interest on the Loans shall be made to Agent for the account of the Lenders PRO RATA in accordance with the respective unpaid principal amounts of such Loans held by the Lenders, and (d) the Revolving Loan Lenders (other than the applicable Issuer) shall purchase from the applicable Issuer participations in each Letter of Credit to the extent of their respective Revolving Loan Commitment Percentages. 4.3 CERTAIN ACTIONS, NOTICES, ETC. Notices to Agent of any termination or reduction of Revolving Loan Commitments and of borrowings and optional prepayments of Loans and requests for issuances of Letters of Credit shall be irrevocable and shall be effective only if received by Agent not later than 11:00 a.m. Houston time on the number of Business Days prior to the date of the relevant termination, reduction, borrowing and/or prepayment specified below: NUMBER OF BUSINESS DAYS PRIOR NOTICE ------------ Borrowing at the Base Rate same day Repayment of Base Rate Borrowing same day Borrowing at Eurodollar Rate 3 LIBOR Business Days Repayment of LIBOR Borrowing prior to last day of the applicable 1 LIBOR Business day Interest Period Letter of Credit issuance 3 Termination or Reduction of Revolving Loan Commitments 3 32 Each such notice of termination or reduction shall specify the amount of the applicable Revolving Loan Commitment to be terminated or reduced. Each such notice of borrowing or prepayment shall specify the amount of the Loans to be borrowed or prepaid and the date of borrowing or prepayment (which shall be a Business Day). Agent shall promptly notify the affected Lenders of the contents of each such notice. Any selection of a Eurodollar Rate with respect to a Loan shall be subject to the advance notice requirements set forth in SECTION 3.3 hereof. 4.4 NON-RECEIPT OF FUNDS BY AGENT. Unless Agent shall have been notified by a Lender or Borrower (the "PAYOR") prior to the date on which such Lender is to make payment to Agent of the proceeds of a Loan (or funding of a drawing under a Letter of Credit or reimbursement with respect to any drawing under a Letter of Credit) to be made by it hereunder or Borrower is to make a payment to Agent for the account of one or more of the Lenders, as the case may be (such payment being herein called the "REQUIRED PAYMENT"), which notice shall be effective upon receipt, that the Payor does not intend to make the Required Payment to Agent, Agent may assume that the Required Payment has been made and may, in reliance upon such assumption (but shall not be required to), make the amount thereof available to the intended recipient on such date and, if the Payor has not in fact made the Required Payment to Agent, the recipient of such payment (or, if such recipient is the beneficiary of a Letter of Credit, Borrower and, if Borrower fails to pay the amount thereof to Agent forthwith upon demand, the Lenders ratably in proportion to their respective Revolving Loan Commitment Percentages) shall, on demand, pay to Agent the amount made available by Agent, together with interest thereon in respect of the period commencing on the date such amount was so made available by Agent until the date Agent recovers such amount at a rate per annum equal to the Federal Funds Rate for such period. 4.5 SHARING OF PAYMENTS, ETC. If a Lender shall obtain payment of any principal of or interest on any Loan made by it under this Agreement, on any Reimbursement Obligation or on any other Obligation then due to such Lender hereunder, through the exercise of any right of set-off (including, without limitation, any right of setoff or lien granted under SECTION 9.2 hereof), banker's lien, counterclaim or similar right, or otherwise, it shall promptly purchase from the other Lenders participations in the Loans made, or Reimbursement Obligations or other Obligations held, by the other Lenders in such amounts, and make such other adjustments from time to time as shall be equitable to the end that all the Lenders shall share the benefit of such payment (net of any expenses which may be incurred by such Lender in obtaining or preserving such benefit) PRO RATA in accordance with the unpaid Obligations then due to each of them. To such end all the Lenders shall make appropriate adjustments among themselves (by the resale of participations sold or otherwise) if such payment is rescinded or must otherwise be restored. Borrower agrees, to the fullest extent it may effectively do so under applicable law, that any Lender so purchasing a participation in the Loans made, or Reimbursement Obligations or other Obligations held, by other Lenders may exercise all rights of set-off, bankers' lien, counterclaim or similar rights with respect to such participation as fully as if such Lender were a direct holder of Loans, or Reimbursement Obligations or other Obligations in the amount of such participation. Nothing contained herein shall require any Lender to exercise any such right or shall affect the right of any Lender to exercise, and retain the benefits of exercising, any such right with respect to any other indebtedness or obligation of Borrower. 33 5. CONDITIONS PRECEDENT. 5.1 INITIAL LOANS AND LETTERS OF CREDIT. The obligation of each Lender or each Issuer to make its initial Loans or issue or participate in a Letter of Credit (if such Letter of Credit is issued prior to the funding of the initial Loans) hereunder is subject to the following conditions precedent, each of which shall have been fulfilled or waived to the satisfaction of Agent: (a) AUTHORIZATION AND STATUS. Agent shall have received from the appropriate Governmental Authorities certified copies of the Organizational Documents (other than by-laws) of each Obligor, and evidence satisfactory to Agent of all action taken by each Obligor authorizing the execution, delivery and performance of the Loan Documents and all other documents related to this Agreement to which it is a party (including, without limitation, a certificate of the secretary of each such party which is a corporation setting forth the resolutions of its Board of Directors authorizing the transactions contemplated thereby and attaching a copy of its bylaws), together with such certificates as may be appropriate to demonstrate the qualification and good standing of and payment of taxes by each Obligor in the jurisdiction of its organization and in each other jurisdiction where the failure in which to qualify would have a Material Adverse Effect. (b) INCUMBENCY. Each Obligor shall have delivered to Agent a certificate in respect of the name and signature of each of the officers (i) who is authorized to sign on its behalf the applicable Loan Documents related to any Loan or the issuance of any Letter of Credit and (ii) who will, until replaced by another officer or officers duly authorized for that purpose, act as its representative for the purposes of signing documents and giving notices and other communications in connection with any Loan or the issuance of any Letter of Credit.

(e) SECURITY MATTERS. All such action as Agent shall have requested to perfect the Liens created pursuant to the Security Documents shall have been taken, including, without limitation, where applicable, the filing and recording of the Security Documents with the appropriate Governmental Authorities.

The obligation of each Lender to make any Loan to be made by it hereunder or to issue or participate in any Letter of Credit is subject to (a) the accuracy, in all material respects, on the date of such Loan or such issuance of all representations and warranties of each Obligor contained in this Agreement and the other Loan Documents; (b) Agent shall have received the following, all of which shall be duly executed and in Proper Form: (1) a Request for Extension of Credit as to the Loan or the Letter of Credit, as the case may be, no later than 11:00 a.m. Houston time on the Business Day on which such Request for Extension of Credit must be given under SECTION 4.3 hereof, (2) in the case of a Letter of Credit, an Application, and (3) such other documents as Agent may reasonably require; (c) prior to the 35 making of such Loan or the issuance of such Letter of Credit, there shall have occurred no event having a Material Adverse Effect; (d) no Default or Event of Default shall have occurred and be continuing; (e) the making of such Loan or the issuance of such Letter of Credit shall not be illegal or prohibited by any Legal Requirement, and (f) Borrower shall have paid all fees and expenses of the type described in SECTION 11.3 hereof and all other fees owed to Agent or any Lender under the Loan Documents which are due and payable, in each case, prior to or on the date of such Loan or such issuance (except for amounts which Agent or the applicable Lender, as the case may be, in their sole discretion, agree may be paid at a later date). The submission by the Borrower of a Request for Extension of Credit shall be deemed to be a representation and warranty that the conditions precedent to the applicable Loan or Letter of Credit have been satisfied. Selection of a new interest rate at the expiration of an Interest Period shall not constitute a new Loan hereunder. 6. REPRESENTATIONS AND WARRANTIES. To induce the Lenders to enter into this Agreement and to make the Loans and issue or participate in the Letters of Credit, Borrower represents and warrants (such representations and warranties to survive any investigation and the making of the Loans and the issuance of any Letters of Credit) to the Lenders and Agent as follows: 6.1 ORGANIZATION. Each Obligor (a) is duly incorporated, validly existing and in good standing under the laws of the jurisdiction of its organization; (b) has all necessary power and authority to conduct its business as presently conducted, and (c) is duly qualified to do business and in good standing in the jurisdiction of its organization and in all jurisdictions in which the failure to so qualify would reasonably be expected to have a Material Adverse Effect. 6.2 FINANCIAL STATEMENTS. Borrower has furnished to Agent (i) audited financial statements (including a balance sheet) as to each Subsidiary of Borrower which fairly present in all material respects, in accordance with GAAP, the combined financial condition and the results of operations of the applicable Person as at the end of such Person's fiscal year ending in 1996, (ii) unaudited pro forma financial statements (including a balance sheet) as to Borrower which fairly present in all material respects, on a pro forma basis but otherwise in accordance with GAAP, the combined financial condition and the results of operations of Borrower as at the end of Borrower's fiscal year ending December 31, 1996, (ii) an unaudited pro forma balance sheet and income statement as to Borrower which fairly present in all material respects, on a pro forma basis but otherwise in accordance with GAAP, the combined financial position and the results of operations of Borrower as at June 30, 1997 and (iii) unaudited interim financial statements for each Subsidiary. No events, conditions or circumstances have occurred from the date that the financial statements were delivered to Agent through the Effective Date which would cause said financial statements to be misleading in any material respect. There are no material instruments or liabilities which should, in accordance with GAAP, be reflected in such financial statements provided to Agent which are not so reflected. 36 6.3 ENFORCEABLE OBLIGATIONS; AUTHORIZATION. The Loan Documents are legal, valid and binding obligations of each applicable Obligor, enforceable in accordance with their respective terms, except as may be limited by bankruptcy, insolvency and other similar laws and judicial decisions affecting creditors' rights generally and by general equitable principles. The execution, delivery and performance of the Loan Documents (a) have all been duly authorized by all necessary action; (b) are within the power and authority of each applicable Obligor; (c) to the best of Borrower's knowledge, do not and will not contravene or violate any Legal Requirement applicable to any applicable Obligor or the Organizational Documents of any applicable Obligor, the contravention or violation of which would reasonably be expected to have a Material Adverse Effect; (d) do not and will not result in the breach of, or constitute a default under, any material agreement or instrument by which any Obligor or any of its Property may be bound, and (e) do not and will not result in the creation of any Lien upon any Property of any Obligor. All necessary permits, registrations and consents for such making and performance have been obtained, except where the failure to obtain the same would not have a Material Adverse Effect. Except as otherwise expressly stated in the Security Documents, the Liens of the Security Documents will constitute valid and perfected first and prior Liens on the Property described therein, subject to no other Liens whatsoever except Permitted Liens covering Collateral other than equity interests in the Subsidiaries of Borrower. 6.4 OTHER DEBT. After giving effect to the initial advance hereunder (and the payment of certain existing Indebtedness of Borrower and its Subsidiaries), no Obligor is in default in the payment of any other Indebtedness or under any agreement, mortgage, deed of trust, security agreement or lease to which it is a party and which would constitute an Event of Default under SECTION 9.1(B). 6.5 LITIGATION. There is no litigation or administrative proceeding, to the knowledge of any executive officer of Borrower, pending or threatened against, nor any outstanding judgment, order or decree against, any Obligor before or by any Governmental Authority which does or would reasonably be expected to have a Material Adverse Effect. No Obligor is in default with respect to any judgment, order or decree of any Governmental Authority where such default would have a Material Adverse Effect. 6.6 TITLE. Each Obligor has good and marketable title to its material Property, free and clear of all Liens except Permitted Liens. 6.7 TAXES. Each Obligor has filed all tax returns required to have been filed and paid all taxes shown thereon to be due, except those for which extensions have been obtained and those which are being contested in good faith. 6.8 REGULATIONS G, U AND X. None of the proceeds of any Loan will be used for the purpose of purchasing or carrying directly or indirectly any margin stock or for any other purpose which would constitute this transaction a "purpose credit" within the meaning of Regulations G, U and X of the Board of Governors of the Federal Reserve System, as any of them may be amended from time to time. 37 6.9 SUBSIDIARIES. As of the Effective Date, Borrower has no Subsidiaries other than those set forth on EXHIBIT F hereto. 6.10 NO UNTRUE OR MISLEADING STATEMENTS. No representation or warranty made by Borrower in any Loan Document or in any document, instrument or other writing furnished to the Lenders by or on behalf of any Obligor in connection with the transactions contemplated in any Loan Document contains any untrue material statement of fact or omits to state any such fact (of which any executive officer of Borrower has knowledge) necessary to make the representations, warranties and other statements contained herein or in such other document, instrument or writing not misleading in any material respect on the date when made or deemed made. 6.11 ERISA. With respect to each Plan, Borrower and each member of the Controlled Group have fulfilled their obligations, including obligations under the minimum funding standards of ERISA and the Code and are in compliance in all material respects with the provisions of ERISA and the Code. No event has occurred which could result in a liability of Borrower or any member of the Controlled Group to the PBGC or a Plan (other than to make contributions in the ordinary course) that would reasonably be expected to have a Material Adverse Effect. There have not been any nor are there now existing any events or conditions that would cause the Lien provided under Section 4068 of ERISA to attach to any Property of Borrower or any member of the Controlled Group. Unfunded Liabilities as of the date hereof do not exceed $500,000. No "prohibited transaction" (for which there is not an exemption) has occurred with respect to any Plan. 6.12 INVESTMENT COMPANY ACT. No Obligor is an investment company within the meaning of the Investment Company Act of 1940, as amended, or, directly or indirectly, controlled by or acting on behalf of any Person which is an investment company, within the meaning of said Act. 6.13 PUBLIC UTILITY HOLDING COMPANY ACT. No Obligor is an "affiliate" or a "subsidiary company" of a "public utility company," or a "holding company," or an "affiliate" or a "subsidiary company" of a "holding company," as such terms are defined in the Public Utility Holding Company Act of 1935, as amended. 6.14 SOLVENCY. None of Borrower, any Obligor, or Borrower and its Subsidiaries, on a consolidated basis, is "insolvent," as such term is used and defined in (i) the Bankruptcy Code and (ii) the fraudulent conveyance statutes of the State of Texas or of any other applicable jurisdiction. 6.15 FISCAL YEAR. The fiscal year of each Obligor ends on December 31. 6.16 COMPLIANCE. To the best knowledge of any executive officer of Borrower, each Obligor is in compliance with all Legal Requirements applicable to it, except to the extent that the failure to comply therewith would not reasonably be expected to have a Material Adverse Effect. 38 6.17 ENVIRONMENTAL MATTERS. Each Obligor has, to the best knowledge of Borrower's executive officers, obtained and maintained in effect all Environmental Permits (or the applicable Person has initiated the necessary steps to transfer the Environmental Permits into its name or obtain such permits), the failure to obtain which would reasonably be expected to have a Material Adverse Effect. Each Obligor and its Properties, business and operations have been and are, to the best knowledge of Borrower's executive officers, in compliance with all applicable Requirements of Environmental Law and Environmental Permits, the failure to comply with which would reasonably be expected to have a Material Adverse Effect. Each Obligor and its Properties, business and operations are not, to the best knowledge of Borrower's executive officers (after making reasonable inquiry of the personnel and records of their respective Corporations), subject to any (a) Environmental Claims or (b) Environmental Liabilities, in either case direct or contingent, arising from or based upon any act, omission, event, condition or circumstance occurring or existing on or prior to the date hereof which would reasonably be expected to have a Material Adverse Effect. None of the officers of Borrower have received nor is aware of any Obligor receiving any notice of any violation or alleged violation of any Requirements of Environmental Law or Environmental Permit or any Environmental Claim in connection with its Properties, liabilities, condition (financial or otherwise), business or operations which would reasonably be expected to have a Material Adverse Effect. Borrower does not know of any event or condition with respect to currently enacted Requirements of Environmental Laws presently scheduled to become effective in the future with respect to any of the Properties of any Obligor which would reasonably be expected to have a Material Adverse Effect, for which the applicable Obligor has not made good faith provisions in its business plan and projections of financial performance. 7. AFFIRMATIVE COVENANTS. Borrower covenants and agrees with Agent and the Lenders that prior to the termination of this Agreement it will do or cause to be done, and cause each other Obligor (unless limited by the language of the applicable provision to less than all of the Obligors) to do or cause to be done, each and all of the following: 7.1 TAXES, EXISTENCE, REGULATIONS, PROPERTY, ETC. At all times (a) pay when due all taxes and governmental charges of every kind upon it or against its income, profits or Property, unless and only to the extent that the same shall be contested diligently in good faith and adequate reserves in accordance with GAAP have been established therefor; (b) do all things necessary to preserve its existence, qualifications, rights and franchises in all jurisdictions where such failure to qualify would reasonably be expected to have a Material Adverse Effect; (c) comply with all applicable Legal Requirements (including without limitation Requirements of Environmental Law) in respect of the conduct of its business and the ownership of its Property, the noncompliance with which would reasonably be expected to have a Material Adverse Effect; and (d) cause its Property to be protected, maintained and kept in good repair (ordinary wear and tear excepted) and make all replacements and additions to such Property as may be reasonably necessary to conduct its business properly and efficiently except where the failure to do so would not reasonably be expected to have a Material Adverse Effect. 39 7.2 FINANCIAL STATEMENTS AND INFORMATION. Furnish to Agent and each Lender each of the following: (a) as soon as available and in any event within 120 days after the end of each applicable fiscal year, beginning with the fiscal year ending on December 31, 1997, Annual Financial Statements of Borrower; (b) as soon as available and in any event within 45 days after the end of each fiscal month (other than the March, June, September and December fiscal months), and as soon as available and in any event within 60 days after the end of each March, June, September and December fiscal month, Monthly Financial Statements of Borrower; (c) concurrently with the financial statements provided for in SUBSECTIONS 7.2(A) and (B) hereof, such schedules, computations and other information, in reasonable detail, as may be required by Agent to demonstrate compliance with the covenants set forth herein or reflecting any non-compliance therewith as of the applicable date, all certified and signed by the president, chief financial officer or treasurer of Borrower (or other authorized officer approved by Agent) as true and correct in all material respects to the best knowledge of such officer and, concurrently with the financial statements provided for in SUBSECTION 7.2(A) hereof and concurrently with the financial statements provided for in SUBSECTIONS 7.2(B) prepared as of each March 31, June 30, September 30 and December 31 commencing with the Monthly Financial Statement prepared as of December 31, 1997, a compliance certificate ("COMPLIANCE CERTIFICATE") in the form of EXHIBIT E hereto, duly executed by such authorized officer; (d) promptly upon their becoming publicly available, each financial statement, report, notice or definitive proxy statements sent by any Obligor to shareholders generally and each regular or periodic report and each registration statement or prospectus filed by any Obligor with any securities exchange or the Securities and Exchange Commission or any successor agency, and (e) such other financial projections and other information relating to the condition (financial or otherwise), operations or business of any Obligor as from time to time may be reasonably requested by Agent. Each delivery of a financial statement pursuant to this SECTION 7.2 shall constitute a restatement of the representations contained in the last two sentences of SECTION 6.2 with respect to the period of time from the date of such most recently delivered financial statements. 7.3 FINANCIAL TESTS. Borrower will have and maintain (in each case, on a consolidated basis for Borrower and its Subsidiaries): (a) MINIMUM NET WORTH - Stockholders' Equity at all times after October 31, 1997 of not less than Stockholders' Equity as of October 31, 1997 PLUS 80% of the Consolidated Net Income (if positive) for the period from and after October 31, 1997 through the date of such calculation PLUS 100% of the net proceeds (whether cash or non-cash) realized from the issuance of any equity securities by Borrower or its Subsidiaries (or other capital contributions made to Borrower) after October 31, 1997.

The use of historical financial results for acquired Subsidiaries in connection with "pooling of interests" accounting shall not serve to cure any default under the covenants set forth in this Section that would otherwise arise. 7.4 INSPECTION. Permit Agent and each Lender upon 1 day's prior notice (unless a Default or an Event of Default has occurred which is continuing, in which case no prior notice is required) to inspect its Property, to examine its files, books and records, except privileged communication with legal counsel and classified governmental material, and make and take away copies thereof, and to discuss its affairs with its officers and accountants, all during normal business hours and at such intervals and to such extent as Agent may reasonably desire. Unless an Event of Default has occurred which is continuing, Agent or the applicable Lender, as the case may be, shall pay its own costs and expenses relating to the exercise of the rights under this Section. 7.5 FURTHER ASSURANCES. Promptly execute and deliver, at Borrower's expense, any and all other and further instruments which may be reasonably requested by Agent to cure any defect in the execution and delivery of any Loan Document in order to effectuate the transactions contemplated by the Loan Documents, and in order to grant, preserve, protect and perfect the validity and priority of the security interests created by the Security Documents. 7.6 BOOKS AND RECORDS. Maintain accounting records which permit financial statements to be prepared in accordance with GAAP. 7.7 INSURANCE. Borrower will (and will cause each of its Subsidiaries to) maintain insurance with such insurers, on such of its Property, with responsible companies in such amounts, with such deductibles and against such risks as are usually carried by owners of similar businesses and properties in the same general areas in which the applicable Person operates or as Agent may otherwise reasonably require, and furnish Agent satisfactory evidence thereof promptly upon request. These insurance provisions are cumulative of the insurance provisions of the Security Documents. Agent shall be provided with copies of the policies of insurance and a certificate of the insurer that the insurance required by this Section may not be canceled, reduced or affected in any material manner without thirty (30) days' prior written notice to Agent. Wherever applicable, such insurance shall name Agent as loss payee and/or mortgagee insured. 7.8 NOTICE OF CERTAIN MATTERS. Give Agent written notice of the following promptly (and in any event within five Business Days) after any executive officer of Borrower shall become aware of the same: (a) the issuance by any court or governmental agency or authority of any injunction, order or other restraint prohibiting, or having the effect of prohibiting, the performance of this Agreement, any other Loan Document, or the making of the Loans or the initiation of any 41 litigation, or any claim or controversy which would reasonably be expected to result in the initiation of any litigation, seeking any such injunction, order or other restraint; (b) the filing or commencement of any action, suit or proceeding, whether at law or in equity or by or before any court or any Governmental Authority involving claims in excess of $1,000,000 (exclusive of claims covered by insurance) or which may reasonably be expected to result in a Default hereunder; (c) any Event of Default or Default, specifying the nature and extent thereof and the action (if any) which is proposed to be taken with respect thereto; (d) the incurrence of material burdensome restrictions under contracts or applicable law which could reasonably be expected to have a Material Adverse Effect and any other event (including strikes, labor disputes or loss of use of material patents or trademarks) which could reasonably be expected to have a Material Adverse Effect; and Borrower will also notify Agent in writing at least 30 days prior to the date that any Obligor changes its name or the location of its chief executive office or principal place of business or the place where it keeps its books and records. 7.9 ERISA INFORMATION AND COMPLIANCE. Promptly furnish to Agent (i) immediately upon receipt, a copy of any notice of complete or partial withdrawal liability under Title IV of ERISA which could reasonably be expected to have a Material Adverse Effect and any notice from the PBGC under Title IV of ERISA of an intent to terminate or appoint a trustee to administer any Plan which could reasonably be expected to have a Material Adverse Effect, (ii) if requested by Agent, promptly after the filing thereof with the United States Secretary of Labor or the PBGC or the Internal Revenue Service, copies of each annual and other report with respect to each Plan or any trust created thereunder, (iii) immediately upon becoming aware of the occurrence of any "reportable event," as such term is defined in Section 4043 of ERISA which could reasonably be expected to have a Material Adverse Effect, for which the disclosure requirements of Regulation Section 2615.3 promulgated by the PBGC have not been waived, or of any "prohibited transaction," as such term is defined in Section 4975 of the Code, in connection with any Plan or any trust created thereunder which could reasonably be expected to have a Material Adverse Effect, a written notice signed by the President or the principal financial officer of Borrower or the applicable member of the Controlled Group specifying the nature thereof, what action Borrower or the applicable member of the Controlled Group is taking or proposes to take with respect thereto, and, when known, any action taken by the PBGC, the Internal Revenue Service or the Department of Labor with respect thereto, (iv) promptly after the filing or receiving thereof by Borrower or any member of the Controlled Group of any notice of the institution of any proceedings or other actions which may result in the termination of any Plan which could reasonably be expected to have a Material Adverse Effect, and (v) each request for waiver of the funding standards or extension of the amortization periods required by Sections 303 and 304 of ERISA or Section 412 of the Code promptly after the request is submitted by Borrower or any member of the Controlled Group to the Secretary of the Treasury, the Department of Labor or the 42 Internal Revenue Service, as the case may be. To the extent required under applicable statutory funding requirements, Borrower will fund, or will cause the applicable member of the Controlled Group to fund, all current service pension liabilities as they are incurred under the provisions of all Plans from time to time in effect, and comply with all applicable provisions of ERISA, in each case, except to the extent that failure to do the same would not reasonably be expected to have a Material Adverse Effect. Except to the extent that failure to do the same would not reasonably be expected to have a Material Adverse Effect, Borrower covenants that it shall and shall cause each member of the Controlled Group to (1) make contributions to each Plan in accordance with the time limits imposed by ERISA and in an amount sufficient to comply with the contribution obligations under such Plan and the minimum funding standards requirements of ERISA; (2) prepare and file in accordance with the time limits imposed by ERISA all notices and reports required under the terms of ERISA including but not limited to annual reports; and (3) pay in accordance with the time limits imposed by ERISA all required PBGC premiums. 8.

Should the right of any Lender to realize funds in any manner set forth hereinabove be challenged and any application of such funds be reversed, whether by court order or otherwise, the Lenders shall make restitution or refund to Borrower pro rata in accordance with their Revolving Loan Commitments. Each Lender agrees to promptly notify Borrower and Agent after any such setoff and application, provided that the 50 failure to give such notice will not affect the validity of such setoff and application. The rights of Agent and the Lenders under this Section are in addition to other rights and remedies (including without limitation other rights of setoff) which Agent or the Lenders may have. This Section is subject to the terms and provisions of SECTIONS 4.5 and 11.7 hereof. 9.3 COLLATERAL ACCOUNT. Borrower hereby agrees, in addition to the provisions of SECTION 9.1 hereof, that upon the occurrence and during the continuance of any Event of Default, it shall, if requested by Agent or the Majority Lenders (through Agent), pay to Agent an amount in immediately available funds equal to the then aggregate amount available for drawings under all Letters of Credit issued for the account of Borrower, which funds shall be held by Agent as Cover. 9.4 PRESERVATION OF SECURITY FOR UNMATURED REIMBURSEMENT OBLIGATIONS. In the event that, following (i) the occurrence of an Event of Default and the exercise of any rights available to Agent or any Lender under the Loan Documents, and (ii) payment in full of the principal amount then outstanding of and the accrued interest on the Loans and Reimbursement Obligations and fees and all other amounts payable hereunder and under the Notes, any Letters of Credit shall remain outstanding and undrawn upon, Agent shall be entitled to hold (and Borrower and each other Obligor hereby grants and conveys to Agent a security interest in and to) all cash or other Property ("PROCEEDS OF REMEDIES") realized or arising out of the exercise of any rights available under the Loan Documents, at law or in equity, including, without limitation, the proceeds of any foreclosure, as collateral for the payment of any amounts due or to become due under or in respect of such Letters of Credit. Such Proceeds of Remedies shall be held for the ratable benefit of the Lenders. The rights, titles, benefits, privileges, duties and obligations of Agent with respect thereto shall be governed by the terms and provisions of this Agreement. Agent may, but shall have no obligation to, invest any such Proceeds of Remedies in such manner as Agent, in the exercise of its sole discretion, deems appropriate. Such Proceeds of Remedies shall be applied to Reimbursement Obligations arising in respect of any such Letters of Credit and/or the payment of any Lender's obligations under any such Letter of Credit when such Letter of Credit is drawn upon. Nothing in this Section shall cause or permit an increase in the maximum amount of the Revolving Loan Obligations permitted to be outstanding from time to time under this Agreement. 9.5 REMEDIES CUMULATIVE. No remedy, right or power conferred upon Agent or any Lender is intended to be exclusive of any other remedy, right or power given hereunder or now or hereafter existing at law, in equity, or otherwise, and all such remedies, rights and powers shall be cumulative. 10. AGENT. 10.1 APPOINTMENT, POWERS AND IMMUNITIES. Each Lender hereby irrevocably appoints and authorizes Agent to act as its agent hereunder, under the Letters of Credit and under the other Loan Documents with such powers as are specifically delegated to Agent by the terms hereof and thereof, together with such other powers as are reasonably incidental thereto. Any Loan Documents executed in favor of Agent shall be held by Agent for the ratable benefit of the 51 Lenders. Agent ("Agent" as used in this SECTION 10 shall include reference to its Affiliates and its own and its Affiliates' respective officers, shareholders, directors, employees and agents) (a) shall not have any duties or responsibilities except those expressly set forth in this Agreement, the Letters of Credit, and the other Loan Documents, and shall not by reason of this Agreement or any other Loan Document be a trustee or fiduciary for any Lender; (b) shall not be responsible to any Lender for any recitals, statements, representations or warranties contained in this Agreement, the Letters of Credit or any other Loan Document, or in any certificate or other document referred to or provided for in, or received by any of them under, this Agreement, the Letters of Credit or any other Loan Document, or for the value, validity, effectiveness, genuineness, enforceability, execution, filing, registration, collectibility, recording, perfection, existence or sufficiency of this Agreement, the Letters of Credit, or any other Loan Document or any other document referred to or provided for herein or therein or any Property covered thereby or for any failure by any Obligor or any other Person to perform any of its obligations hereunder or thereunder, and shall not have any duty to inquire into or pass upon any of the foregoing matters; (c) shall not be required to initiate or conduct any litigation or collection proceedings hereunder or under the Letters of Credit or any other Loan Document except to the extent requested by the Majority Lenders; (d) shall not be responsible for any mistake of law or fact or any action taken or omitted to be taken by it hereunder or under the Letters or Credit or any other Loan Document or any other document or instrument referred to or provided for herein or therein or in connection herewith or therewith, including, without limitation, pursuant to its own negligence, except for its own gross negligence or willful misconduct; (e) shall not be bound by or obliged to recognize any agreement among or between Borrower and any Lender to which Agent is not a party, regardless of whether Agent has knowledge of the existence of any such agreement or the terms and provisions thereof; (f) shall not be charged with notice or knowledge of any fact or information not herein set out or provided to Agent in accordance with the terms of this Agreement or any other Loan Document; (g) shall not be responsible for any delay, error, omission or default of any mail, telegraph, cable or wireless agency or operator, and (h) shall not be responsible for the acts or edicts of any Governmental Authority. Agent may employ agents and attorneys-in-fact and shall not be responsible for the negligence or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. Without in any way limiting any of the foregoing, each Lender acknowledges that Agent shall have no greater responsibility in the operation of the Letters of Credit than is specified in the Uniform Customs and Practice for Documentary Credits (1993 Revision, International Chamber of Commerce Publication No. 500). In any foreclosure proceeding concerning any Collateral, each holder of an Obligation if bidding for its own account or for its own account and the accounts of other Lenders is prohibited from including in the amount of its bid an amount to be applied as a credit against the Obligations held by it or the Obligations held by the other Lenders; instead, such holder must bid in cash only. However, in any such foreclosure proceeding, Agent may (but shall not be obligated to) submit a bid for all Lenders (including itself) in the form of a credit against the Obligations, and Agent or its designee may (but shall not be obligated to) accept title to such collateral for and on behalf of all Lenders. 10.2 RELIANCE. Agent shall be entitled to rely upon any certification, notice or other communication (including any thereof by telephone, telex, telegram or cable) believed by it to be 52 genuine and correct and to have been signed or sent by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel (which may be counsel for Borrower), independent accountants and other experts selected by Agent. Agent shall not be required in any way to determine the identity or authority of any Person delivering or executing the same. As to any matters not expressly provided for by this Agreement, the Letters of Credit, or any other Loan Document, Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and thereunder in accordance with instructions of the Majority Lenders, and any action taken or failure to act pursuant thereto shall be binding on all of the Lenders. Pursuant to instructions of the Majority Lenders, Agent shall have the authority to execute releases of the Security Documents on behalf of the Lenders without the joinder of any Lender. If any order, writ, judgment or decree shall be made or entered by any court affecting the rights, duties and obligations of Agent under this Agreement or any other Loan Document, then and in any of such events Agent is authorized, in its sole discretion, to rely upon and comply with such order, writ, judgment or decree which it is advised by legal counsel of its own choosing is binding upon it under the terms of this Agreement, the relevant Loan Document or otherwise; and if Agent complies with any such order, writ, judgment or decree, then it shall not be liable to any Lender or to any other Person by reason of such compliance even though such order, writ, judgment or decree may be subsequently reversed, modified, annulled, set aside or vacated. 10.3 DEFAULTS. Agent shall not be deemed to have knowledge of the occurrence of a Default (other than the non-payment of principal of or interest on Loans or Reimbursement Obligations) unless Agent has received notice from a Lender or Borrower specifying such Default and stating that such notice is a "NOTICE OF DEFAULT." In the event that Agent receives such a Notice of Default, Agent shall give prompt notice thereof to the Lenders (and shall give each Lender prompt notice of each such non-payment). Agent shall (subject to SECTION 10.7 hereof) take such action with respect to such Notice of Default as shall be directed by the Majority Lenders and within its rights under the Loan Documents and at law or in equity, PROVIDED that, unless and until Agent shall have received such directions, Agent may (but shall not be obligated to) take such action, or refrain from taking such action, permitted hereby with respect to such Notice of Default as it shall deem advisable in the best interests of the Lenders and within its rights under the Loan Documents, at law or in equity. 10.4 MATERIAL WRITTEN NOTICES. In the event that Agent receives any written notice of a material nature from the Borrower or any Obligor under the Loan Documents, Agent shall promptly inform each of the Lenders thereof. 10.5 RIGHTS AS A LENDER. With respect to its Revolving Loan Commitments and the Loans made and Letter of Credit Liabilities, TCB in its capacity as a Lender hereunder shall have the same rights and powers hereunder as any other Lender and may exercise the same as though it were not acting in its agency capacity, and the term "LENDER" or "LENDERS" shall, unless the context otherwise indicates, include Agent in its individual capacity. Agent may (without having to account therefor to any Lender) accept deposits from, lend money to and generally engage in any kind of banking, trust, letter of credit, agency or other business with Borrower (and any of its Affiliates) as if it were not acting as Agent, and Agent may accept fees and other consideration 53 from Borrower (in addition to the fees heretofore agreed to between Borrower and Agent) for services in connection with this Agreement or otherwise without having to account for the same to the Lenders. 10.6 INDEMNIFICATION. The Lenders agree to indemnify Agent (to the extent not reimbursed under SECTION 2.2(C), SECTION 11.3 or SECTION 11.4 hereof, but without limiting the obligations of Borrower under said SECTIONS 2.2(C), 11.3 and 11.4), ratably in accordance with the Lenders' respective Revolving Loan Commitments, for any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever, REGARDLESS OF WHETHER CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE OF ANY INDEMNIFIED PARTIES, which may be imposed on, incurred by or asserted against Agent in any way relating to or arising out of this Agreement, the Letters of Credit or any other Loan Document or any other documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby (including, without limitation, the costs and expenses which Borrower is obligated to pay under SECTIONS 2.2(C), 11.3 and 11.4 hereof, interest, penalties, attorneys' fees and amounts paid in settlement, but excluding, unless a Default has occurred and is continuing, normal administrative costs and expenses incident to the performance of its agency duties hereunder) or the enforcement of any of the terms hereof or thereof or of any such other documents; PROVIDED that no Lender shall be liable for any of the foregoing to the extent they arise from the gross negligence or willful misconduct of the party to be indemnified. The obligations of the Lenders under this SECTION 10.6 shall survive the termination of this Agreement and the repayment of the Obligations. 10.7 NON-RELIANCE ON AGENT AND OTHER LENDERS. Each Lender agrees that it has received current financial information with respect to Borrower and each other Obligor that it has, independently and without reliance on Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis of Borrower and each other Obligor and decision to enter into this Agreement and that it will, independently and without reliance upon Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under this Agreement or any of the other Loan Documents. Agent shall not be required to keep itself informed as to the performance or observance by any Obligor of this Agreement, the Letters of Credit or any of the other Loan Documents or any other document referred to or provided for herein or therein or to inspect the properties or books of any Obligor. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by Agent hereunder, under the Letters of Credit or the other Loan Documents, Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or business of any Obligor (or any of their affiliates) which may come into the possession of Agent. 10.8 FAILURE TO ACT. Except for action expressly required of Agent hereunder, under the Letters of Credit or under the other Loan Documents, Agent shall in all cases be fully justified in failing or refusing to act hereunder and thereunder unless it shall receive further assurances to its satisfaction by the Lenders of their indemnification obligations under SECTION 10.6 hereof against 54 any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. 10.9 RESIGNATION OR REMOVAL OF AGENT. Subject to the appointment and acceptance of a successor Agent as provided below, Agent may resign at any time by giving notice thereof to the Lenders and Borrower, and Agent may be removed at any time with or without cause by the Majority Lenders; PROVIDED, that Agent shall continue as Agent until such time as any successor shall have accepted appointment as Agent hereunder. Upon any such resignation or removal, (i) the Majority Lenders without the consent of Borrower shall have the right to appoint a successor Agent so long as such successor Agent is also a Lender at the time of such appointment and (ii) the Majority Lenders shall have the right to appoint a successor Agent that is not a Lender at the time of such appointment so long as Borrower consents to such appointment (which consent shall not be unreasonably withheld). If no successor Agent shall have been so appointed by the Majority Lenders and accepted such appointment within 30 days after the retiring Agent's giving of notice of resignation or the Majority Lenders' removal of the retiring Agent, then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent. Any successor Agent shall be a bank which has an office in the United States and a combined capital and surplus of at least $250,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent and the retiring Agent shall be discharged from its duties and obligations hereunder and under any other Loan Documents. Such successor Agent shall promptly specify by notice to Borrower its Principal Office referred to in SECTION 3.1 and SECTION 4 hereof. After any retiring Agent's resignation or removal hereunder as Agent, the provisions of this SECTION 10 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Agent. 10.10 NO PARTNERSHIP. Neither the execution and delivery of this Agreement nor any of the other Loan Documents nor any interest the Lenders, Agent or any of them may now or hereafter have in all or any part of the Obligations shall create or be construed as creating a partnership, joint venture or other joint enterprise between the Lenders or among the Lenders and Agent. The relationship between the Lenders, on the one hand, and Agent, on the other, is and shall be that of principals and agent only, and nothing in this Agreement or any of the other Loan Documents shall be construed to constitute Agent as trustee or other fiduciary for any Lender or to impose on Agent any duty, responsibility or obligation other than those expressly provided for herein and therein. 11. MISCELLANEOUS. 11.1 WAIVER. No waiver of any Default or Event of Default shall be a waiver of any other Default or Event of Default. No failure on the part of Agent or any Lender to exercise and no delay in exercising, and no course of dealing with respect to, any right, power or privilege under any Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege thereunder preclude any other or further exercise thereof 55 or the exercise of any other right, power or privilege. The remedies provided in the Loan Documents are cumulative and not exclusive of any remedies provided by law or in equity. 11.2 NOTICES. All notices and other communications provided for herein (including, without limitation, any modifications of, or waivers or consents under, this Agreement) shall be given or made by telex, telegraph, telecopy (confirmed by mail), cable or other writing and telexed, telecopied, telegraphed, cabled, mailed or delivered to the intended recipient at the "Address for Notices" specified below its name on the signature pages hereof (or provided for in an Assignment and Acceptance); or, as to any party hereto, at such other address as shall be designated by such party in a notice (given in accordance with this Section) (i) as to Borrower, to Agent, (ii) as to Agent, to Borrower and to each Lender, and (iii) as to any Lender, to Borrower and Agent.

Whether or not any Loan is ever made or any Letter of Credit ever issued, Borrower shall pay or reimburse within 10 days after written demand (a) Agent for paying the reasonable fees and expenses of legal counsel to Agent in connection with the preparation, negotiation, execution and delivery of this Agreement (including the exhibits and schedules hereto), the other Loan Documents and the making of the Loans and the issuance of Letters of Credit hereunder, and any modification, supplement or waiver of any of the terms of this Agreement, the Letters of Credit or any other Loan Document; (b) Agent for any lien search fees; (c) Agent for reasonable out-of-pocket expenses incurred by Agent in connection with the preparation, documentation, administration and syndication of the Loans or any of the Loan Documents (including, without limitation, the marketing, printing, duplicating, mailing and similar expenses) of the Loans and Letter of Credit Liabilities; (d) Agent for paying all transfer, stamp, documentary or other similar taxes, assessments or charges levied by any governmental or revenue authority in respect of this Agreement, any Letter of Credit or any other Loan Document or any other document referred to herein or therein; (e) Agent for paying all costs, expenses, taxes, assessments and other charges incurred in connection with any filing, registration, recording or perfection of any security interest contemplated by this Agreement or any document referred to herein and (f) following the occurrence and during the continuation of an Event of Default, any Lender or Agent for paying all amounts reasonably expended, advanced or incurred by such Lender or Agent to satisfy any obligation of any Obligor under this Agreement or any other Loan Document, to protect Collateral, to collect the Obligations or to enforce, protect, preserve or defend the rights of the Lenders or Agent under this Agreement or any other Loan Document, including, without limitation, fees and expenses incurred in connection with such Lender's or Agent's participation as a member of a creditor's committee in a case commenced under the Bankruptcy Code or other similar law, fees and expenses incurred in connection with lifting the automatic stay prescribed in ss. 362 of the Bankruptcy Code and fees and expenses incurred in connection with any action pursuant to ss. 1129 of the Bankruptcy Code and all other customary 56 out-of-pocket expenses incurred by such Lender or Agent in connection with such matters, together with interest thereon at the Past Due Rate on each such amount until the date of reimbursement to such Lender or Agent. 11.4 INDEMNIFICATION. Borrower shall indemnify each of Agent, the Lenders, and each Affiliate thereof and their respective directors, officers, employees and agents from, and hold each of them harmless against, any and all losses, liabilities, claims or damages to which any of them may become subject, REGARDLESS OF WHETHER CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE OF ANY INDEMNIFIED PARTIES, insofar as such losses, liabilities, claims or damages arise out of or result from any (i) actual or proposed use by Borrower of the proceeds of any extension of credit (whether a Loan or a Letter of Credit) by any Lender hereunder; (ii) breach by any Obligor of this Agreement or any other Loan Document; (iii) violation by any Obligor of any Legal Requirement; (iv) investigation, litigation or other proceeding relating to any of the foregoing, and Borrower shall reimburse Agent, each Lender, and each Affiliate thereof and their respective directors, officers, employees and agents, upon demand for any reasonable expenses (including reasonable legal fees) incurred in connection with any such investigation or proceeding, or (v) taxes (excluding income taxes and franchise taxes) payable or ruled payable by any Governmental Authority in respect of the Obligations or any Loan Document, together with interest and penalties, if any; PROVIDED that Borrower shall not be required to indemnify any party seeking indemnification for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by (i) the willful misconduct or gross negligence of the party seeking indemnification, or (ii) the failure by the party seeking indemnification to pay under any Letter of Credit after the presentation to it of a request required to be paid under applicable law or (iii) disputes between or among any and all of Agent, Lenders and Issuers.. Nothing in this Section is intended to limit the obligations of Borrower under any other provision of this Agreement. Agent and each Lender, respectively, shall indemnify Borrower and hold Borrower harmless from and against the gross negligence or willful misconduct of Agent or such Lender, as the case may be. 11.5 AMENDMENTS, ETC. No amendment or modification of this Agreement, the Notes or any other Loan Document shall in any event be effective against Borrower unless the same shall be agreed or consented to in writing by Borrower. No amendment, modification or waiver of any provision of this Agreement, the Notes or any other Loan Document, nor any consent to any departure by Borrower therefrom, shall in any event be effective against the Lenders unless the same shall be agreed or consented to in writing by the Majority Lenders, and each such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; PROVIDED, that no amendment, modification, waiver or consent shall, unless in writing and signed by each Lender affected thereby, do any of the following: (a) increase any Revolving Loan Commitment of any of the Lenders (or reinstate any termination or reduction of the Revolving Loan Commitments) or subject any of the Lenders to any additional obligations; (b) reduce the principal of, or interest on, any Loan, Reimbursement Obligation or fee hereunder; (c) postpone or extend the Revolving Loan Maturity Date, the Revolving Loan Termination Date, the Revolving Loan Availability Period or any scheduled date fixed for any payment of principal of, or interest on, any Loan, Reimbursement Obligation, fee or other sum to be paid hereunder or 57 waive any Event of Default described in SECTION 9.1(A) hereof; (d) change the percentage of any of the Revolving Loan Commitments or of the aggregate unpaid principal amount of any of the Loans and Letter of Credit Liabilities, or the percentage of Lenders, which shall be required for the Lenders or any of them to take any action under this Agreement (including, without linitation, the definition of "Majority Lenders"); (e) change any provision contained in SECTIONS 2.2(C), 3.4, 11.3 OR 11.4 hereof or this SECTION 11.5; (f) release any Person from liability under a Guaranty or substantially all of the security for the Obligations or release Collateral (exclusive of Collateral with respect to which Agent is obligated to provide a release pursuant to this Agreement or any of the other Loan Documents or by law) in any one (1) calendar year ascribed an aggregate value on the most recent financial statements of Borrower delivered to Agent in excess of $1,000,000, or (g) modify the provisions of SECTIONS 4.1(B) or 4.2 hereof regarding PRO RATA application of amounts after an Event of Default shall have occurred and be continuing. Notwithstanding anything in this SECTION 11.5 to the contrary, no amendment, modification, waiver or consent shall be made with respect to SECTION 10 without the consent of Agent to the extent it affects Agent, as Agent. 11.6 SUCCESSORS AND ASSIGNS. (a) This Agreement shall be binding upon and inure to the benefit of Borrower, Agent and the Lenders and their respective successors and assigns; PROVIDED, HOWEVER, that Borrower may not assign or transfer any of its rights or obligations hereunder without the prior written con sent of all of the Lenders, and any such assignment or transfer without such consent shall be null and void. Each Lender may sell participations to any Person in all or part of any Loan, or all or part of its Notes, Revolving Loan Commitments or interests in Letters of Credit, in which event, without limiting the foregoing, the provisions of the Loan Documents shall inure to the benefit of each purchaser of a participation; PROVIDED, HOWEVER, the PRO RATA treatment of payments, as described in SECTION 4.2 hereof, shall be determined as if such Lender had not sold such participation. Any Lender that sells one or more participations to any Person shall not be relieved by virtue of such participation from any of its obligations to Borrower under this Agreement relating to the Loans. In the event any Lender shall sell any participation, such Lender shall retain the sole right and responsibility to enforce the obligations of Borrower relating to the Loans, including, without limitation, the right to approve any amendment, modification or waiver of any provision of this Agreement other than amendments, modifications or waivers with respect to (i) any fees payable hereunder to the Lenders, (ii) the amount of principal or the rate of interest payable on, or the dates fixed for the scheduled repayment of principal of, the Loans and (iii) the release of the Liens on all or substantially all of the Collateral. (b) Each Lender may assign to one or more Lenders or any other Person all or a portion of its interests, rights and obligations under this Agreement; PROVIDED, HOWEVER, that (i) the aggregate amount of the Revolving Loan Commitments of the assigning Lender subject to each such assignment shall in no event be less than $5,000,000; (ii) other than in the case of an assignment to another Lender (that is, at the time of the assignment, a party hereto) or to an Affiliate of such Lender or to a Federal Reserve Bank, Agent and, so long as no Event of Default shall have occurred and be continuing, Borrower must each give its prior written consent, which 58 consents shall not be unreasonably withheld, and (iii) the parties to each such assignment shall execute and deliver to Agent, for its acceptance an Assignment and Acceptance in the form of EXHIBIT D hereto (each an "ASSIGNMENT AND ACCEPTANCE") with blanks appropriately completed, together with any Note or Notes subject to such assignment and a processing and recording fee of $3,000 paid by the assignee (for which Borrower will have no liability). Upon such execution, delivery and acceptance, from and after the effective date specified in each Assignment and Acceptance, (A) the assignee thereunder shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights and obligations of a Lender hereunder and (B) the Lender thereunder shall, to the extent provided in such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto except in respect of provisions of this Agreement which survive payment of the Obligations and termination of the Commitments). Notwithstanding anything contained in this Agreement to the contrary, any Lender may at any time assign all or any portion of its rights under this Agreement and the Notes issued to it as collateral to a Federal Reserve Bank; provided that no such assignment shall release such Lender from any of its obligations hereunder. (c) By executing and delivering an Assignment and Acceptance, the Lender assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than the representation and warranty that it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim, such Lender assignor makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or any of the other Loan Documents or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any of the other Loan Documents or any other instrument or document furnished pursuant thereto; (ii) such Lender assignor makes no representation or warranty and assumes no responsibility with respect to the financial condition of Borrower or the performance or observance by Borrower of any of its obligations under this Agreement or any of the other Loan Documents or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in SECTION 6.2 hereof and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon Agent, such Lender assignor or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Loan Documents; (v) such assignee appoints and authorizes Agent to take such action as agent on its behalf and to exercise such powers under this Agreement and the other Loan Documents as are delegated to Agent by the terms hereof, together with such powers as are reasonably incidental thereto; and (vi) such assignee agrees that it will perform in accordance with their terms all obligations that by the terms of this Agreement and the other Loan Documents are required to be performed by it as a Lender. 59 (d) The entries in the records of Agent as to each Assignment and Acceptance delivered to it and the names and addresses of the Lenders and the Revolving Loan Commitments of, and principal amount of the Loans owing to, each Lender from time to time shall create a rebuttable presumption as to the accuracy thereof and Borrower, Agent and the Lenders may treat each Person the name of which is recorded in the books and records of Agent as a Lender hereunder for all purposes of this Agreement and the other Loan Documents. (e) Upon Agent's receipt of an Assignment and Acceptance executed by an assigning Lender and the assignee thereunder, together with any Note or Notes subject to such assignment and the written consent to such assignment (to the extent consent is required), Agent shall, if such Assignment and Acceptance has been completed with blanks appropriately filled, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in its records and (iii) give prompt notice thereof to Borrower. Within ten (10) Business Days after receipt of notice, Borrower, at its own expense, shall execute and deliver to Agent in exchange for the surrendered Notes new Notes to the order of such assignee in an amount equal to the Revolving Loan Commitments assumed by it pursuant to such Assignment and Acceptance and, if the assigning Lender has retained Revolving Loan Commitments hereunder, new Notes to the order of the assigning Lender in an amount equal to the Revolving Loan Commitment retained by it hereunder. Such new Notes shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered Notes, shall be dated the effective date of such Assignment and Acceptance and shall otherwise be in substantially the form of the respective Note. Thereafter, such surrendered Notes shall be marked renewed and substituted and the originals thereof delivered to Borrower (with copies, certified by Borrower as true, correct and complete, to be retained by Agent). (f) Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this SECTION 11.6, disclose to the assignee or participant or proposed assignee or participant, any information relating to Borrower furnished to such Lender by or on behalf of Borrower. 11.7 LIMITATION OF INTEREST. Borrower and the Lenders intend to strictly comply with all applicable federal and Texas laws, including applicable usury laws (or the usury laws of any jurisdiction whose usury laws are deemed to apply to the Notes or any other Loan Documents despite the intention and desire of the parties to apply the usury laws of the State of Texas). Accordingly, the provisions of this SECTION 11.7 shall govern and control over every other provision of this Agreement or any other Loan Document which conflicts or is inconsistent with this Section, even if such provision declares that it controls. As used in this Section, the term "interest" includes the aggregate of all charges, fees, benefits or other compensation which constitute interest under applicable law, PROVIDED that, to the maximum extent permitted by applicable law, (a) any non-principal payment shall be characterized as an expense or as compensation for something other than the use, forbearance or detention of money and not as interest, and (b) all interest at any time contracted for, reserved, charged or received shall be amortized, prorated, allocated and spread, in equal parts during the full term of the Obligations. In no event shall Borrower or any other Person be obligated to pay, or any Lender have any right 60 or privilege to reserve, receive or retain, (a) any interest in excess of the maximum amount of nonusurious interest permitted under the laws of the State of Texas or the applicable laws (if any) of the United States or of any other jurisdiction, or (b) total interest in excess of the amount which such Lender could lawfully have contracted for, reserved, received, retained or charged had the interest been calculated for the full term of the Obligations at the Ceiling Rate. The daily interest rates to be used in calculating interest at the Ceiling Rate shall be determined by dividing the applicable Ceiling Rate per annum by the number of days in the calendar year for which such calculation is being made. None of the terms and provisions contained in this Agreement or in any other Loan Document (including, without limitation, SECTION 9.1 hereof) which directly or indirectly relate to interest shall ever be construed without reference to this SECTION 11.7, or be construed to create a contract to pay for the use, forbearance or detention of money at an interest rate in excess of the Ceiling Rate. If the term of any Obligation is shortened by reason of acceleration of maturity as a result of any Default or by any other cause, or by reason of any required or permitted prepayment, and if for that (or any other) reason any Lender at any time, including but not limited to, the stated maturity, is owed or receives (and/or has received) interest in excess of interest calculated at the Ceiling Rate, then and in any such event all of any such excess interest shall be canceled automatically as of the date of such acceleration, prepayment or other event which produces the excess, and, if such excess interest has been paid to such Lender, it shall be credited PRO TANTO against the then-outstanding principal balance of Borrower's obligations to such Lender, effective as of the date or dates when the event occurs which causes it to be excess interest, until such excess is exhausted or all of such principal has been fully paid and satisfied, whichever occurs first, and any remaining balance of such excess shall be promptly refunded to its payor. 11.8 SURVIVAL. The obligations of Borrower under SECTIONS 2.2(C), 2.2(D), 3.4, 11.3 AND 11.4 hereof and all other obligations of Borrower in any other Loan Document (to the extent stated therein), the obligations of each Issuer under the last sentence of SECTION 2.2(B)(III) and the obligations of the Lenders under SECTION 10.5 and 11.7 hereof, shall, notwithstanding anything herein to the contrary, survive the repayment of the Loans and Reimbursement Obligations and the termination of the Revolving Loan Commitments and the Letters of Credit. 11.9 CAPTIONS. Captions and section headings appearing herein are included solely for convenience of reference and are not intended to affect the interpretation of any provision of this Agreement. 11.10 COUNTERPARTS. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same agreement and any of the parties hereto may execute this Agreement by signing any such counterpart. 11.11 GOVERNING LAW. THIS AGREEMENT AND (EXCEPT AS THEREIN PROVIDED) THE OTHER LOAN DOCUMENTS SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE APPLICABLE LAWS OF THE STATE OF TEXAS AND THE UNITED STATES OF AMERICA FROM TIME TO TIME IN EFFECT. 61 11.12 SEVERABILITY. Whenever possible, each provision of the Loan Documents shall be interpreted in such manner as to be effective and valid under applicable law. If any provision of any Loan Document shall be invalid, illegal or unenforceable in any respect under any applicable law, the validity, legality and enforceability of the remaining provisions of such Loan Document shall not be affected or impaired thereby. 11.13 TAX FORMS. Each Lender which is organized under the laws of a jurisdiction outside the United States shall, on the day of the initial borrowing from each such Lender hereunder and from time to time thereafter if requested by Borrower or Agent, provide Agent and Borrower with the forms prescribed by the Internal Revenue Service of the United States certifying as to such Lender's status for purposes of determining exemption from United States withholding taxes with respect to all payments to be made to such Lender hereunder or other documents satisfactory to such Lender, Borrower and Agent indicating that all payments to be made to such Lender hereunder are not subject to United States withholding tax or are subject to such tax at a rate reduced by an applicable tax treaty. Unless Borrower and Agent shall have received such forms or such documents indicating that payments hereunder are not subject to United States withholding tax or are subject to such tax at a rate reduced by an applicable tax treaty, Borrower or Agent shall withhold taxes from such payments at the applicable statutory rate. 11.14 CONFLICTS BETWEEN THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS. In the event of any conflict between the terms of this Agreement and the terms of any of the other Loan Documents, the terms of this Agreement shall control. 11.15 DISCLOSURE TO OTHER PERSONS; CONFIDENTIALITY. Agent and each Lender agree that it may deliver copies of any financial statements and other documents or information delivered to it and disclose any other information disclosed to it by or on behalf of Borrower or any Subsidiary of Borrower in connection with or pursuant to this Agreement and the other Loan Documents only to: (i) its directors, officers, employees and professional consultants; (ii) any other Lender; (iii) any Person to which such Lender offers to sell its Note or any part thereof, provided that each such Person agrees in writing to observe the confidentiality standards described in this Section; (iv) any Person to which such Lender sells or offers to sell a participation in all or any part of its Note, PROVIDED that each such Person agrees in writing to observe the confidentiality standards described in this Section; (v) any federal or state regulatory authority having jurisdiction over it; 62 (vi) any other Person to which such delivery or disclosure may be necessary or reasonably appropriate in response to any subpoena or other legal process or investigative demand, and (vii) any other Person in connection with any litigation involving any obligation, right or remedy of Agent or any Lender under the Loan Documents. Subject to the foregoing, Agent and each Lender hereby agrees to use its best efforts to hold in confidence and not to disclose any Confidential Information; PROVIDED, that such Person will be free, after notice to Borrower, to correct any false or misleading information which may become public concerning its relationship to Borrower. For the purpose of this Section, the term "CONFIDENTIAL INFORMATION" shall mean information about Borrower or any Subsidiary of Borrower furnished by Borrower or any such Subsidiary, but does not include any information which (i) is publicly known, or otherwise known to such holder, at the time of disclosure; (ii) subsequently becomes publicly known, but not through any act or omission by such holder, or (iii) otherwise becomes known to such holder other than through disclosure by Borrower or any Subsidiary of Borrower. IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the Effective Date.

Any term defined in the Loan Agreement which is used in this note and which is not otherwise defined in this note shall have the meaning ascribed to it in the Loan Agreement. 1. LOAN AGREEMENT; ADVANCES; SECURITY. This note has been issued pursuant to the terms of the Loan Agreement, and is one of the Notes referred to in the Loan Agreement. Advances against this note by Payee or other holder hereof shall be governed by the terms and provisions of the Loan Agreement. Reference is hereby made to the Loan Agreement for all purposes. Payee is entitled to the benefits of the Loan Agreement. The unpaid principal balance of this note at any time shall be the total of all amounts lent or advanced against this note less the amount of all payments or permitted prepayments made on this note and by or for the account of Maker. All loans and advances and all payments and permitted prepayments made hereon may be endorsed by the holder of this note on a schedule which may be attached hereto (and thereby made a part hereof for all purposes) or otherwise recorded in the holder's records; PROVIDED, that any failure to make notation of (a) any advance shall not cancel, limit or otherwise affect Maker's obligations or any holder's rights with respect to that advance, or (b) any payment or permitted prepayment of principal shall not cancel, limit or otherwise affect Maker's entitlement to credit for that payment as of the date received by the holder. EXHIBIT C to Loan Agreement -1- 2. MANDATORY PAYMENTS OF PRINCIPAL AND INTEREST. (a) Accrued and unpaid interest on the unpaid principal balance of this note shall be due and payable on the Interest Payment Dates. (b) On the Revolving Loan Maturity Date, the entire unpaid principal balance of this note and all accrued and unpaid interest on the unpaid principal balance of this note shall be finally due and payable. (c) All payments hereon made pursuant to this Paragraph shall be applied first to accrued interest, the balance to principal. (d) If any payment provided for in this note shall become due on a day other than a Business Day, such payment may be made on the next succeeding Business Day (unless the result of such extension of time would be to extend the date for such payment into another calendar month or beyond the Revolving Loan Maturity Date, and in either such event such payment shall be made on the Business Day immediately preceding the day on which such payment would otherwise have been due), and such extension of time shall in such case be included in the computation of interest on this note.

In furtherance thereof, none of the terms of this note or any of the other Loan Documents shall ever be construed to create a contract to pay, as consideration for the use, forbearance or detention of money, interest at a rate in excess of the Ceiling Rate. Maker or other parties now or hereafter becoming liable for payment of the indebtedness evidenced by this note shall never be liable for interest in excess of the Ceiling Rate. If, for any reason whatever, the interest paid or received on this note during its full term produces a rate which exceeds the Ceiling Rate, the holder of this note shall credit against the principal of this note (or, if such indebtedness shall have been paid in full, shall refund to the payor of such interest) such portion of said interest as shall be EXHIBIT C to Loan Agreement -2- necessary to cause the interest paid on this note to produce a rate equal to the Ceiling Rate. All sums paid or agreed to be paid to the holder of this note for the use, forbearance or detention of the indebtedness evidenced hereby shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread in equal parts throughout the full term of this note, so that the interest rate is uniform throughout the full term of this note. The provisions of this Paragraph shall control all agreements, whether now or hereafter existing and whether written or oral, between Maker and Payee. 4. DEFAULT. The Loan Agreement provides for the acceleration of the maturity of this note and other rights and remedies upon the occurrence of certain events specified therein. 5. WAIVERS BY MAKER AND OTHERS.

Each such person agrees that his, her or its liability on or with respect to this note shall not be affected by any release of or change in any guaranty or security at any time existing or by any failure to perfect or to maintain perfection of any lien against or security interest in any such security or the partial or complete unenforceability of any guaranty or other surety obligation, in each case in whole or in part, with or without notice and before or after maturity. 6. PARAGRAPH HEADINGS. Paragraph headings appearing in this note are for convenient reference only and shall not be used to interpret or limit the meaning of any provision of this note. 7. CHOICE OF LAW. THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE APPLICABLE LAWS OF THE STATE OF TEXAS AND THE UNITED STATES OF AMERICA FROM TIME TO TIME IN EFFECT. 8. SUCCESSORS AND ASSIGNS. This note and all the covenants and agreements contained herein shall be binding upon, and shall inure to the benefit of, the respective legal representatives, heirs, successors and assigns of Maker and Payee. 9. SEVERABILITY.

Pursuant to Article 15.10(b) of Chapter 15 ("CHAPTER 15") of Title 79, Texas Revised Civil Statutes, 1925, as amended, Maker and Payee expressly agree that Chapter 15 shall not apply to this note or to any loan evidenced by this note and that neither this note nor any such loan shall be governed by or subject to the provisions of Chapter 15 in any manner whatsoever. 11. BUSINESS LOANS. Maker warrants and represents to Payee and all other holders of this note that all loans evidenced by this note are and will be for business, commercial, investment or other similar purpose and not primarily for personal, family, household or agricultural use, as such terms are used in Chapter One.
