Borrower and each of its Subsidiaries is in compliance with all laws pertaining to health or the environment ("Applicable Environmental Laws"), including, without limitation, the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended ("CERCLA"), the Resource Conservation and Recovery Act of 1976, as amended ("RCRA"), the Texas Water Code and the Texas Solid Waste Disposal Act. Borrower's and its Subsidiaries' operations do not and will not result in the disposal or release of any hazardous substance or Hazard on, in or to the environment. The terms "hazardous substance" and "release" shall each have the meanings specified in CERCLA, and the terms "solid waste" and "disposal" (or "disposed") shall each have the meanings specified in RCRA; provided, however, that in the event either CERCLA or RCRA is amended so as to broaden the meaning of any term defined thereby, such broader meaning shall apply subsequent to the effective date of such amendment; and provided further that, to the extent that the laws of the State of Texas or any other State in which business is being conducted establish a meaning for "hazardous substance", "release", "solid waste", or "disposal" which is broader than specified in either CERCLA or RCRA, such broader definition shall apply. 25 26 5.11 Investment Company Act. Borrower is not an "investment company" or a company "controlled" by an "investment company" within the meaning of the Investment Company Act of 1940, as amended. SECTION 6. AFFIRMATIVE COVENANTS.

Each Lender hereby authorizes Agent to take such action on such Lender's behalf and exercise such powers as are delegated to Agent by the terms hereof, together with all such powers as are reasonably incidental thereto. The relationship between Agent and each Lender is that of agent and principal only, and nothing herein shall (nor shall it be construed so as to) constitute Agent a trustee or fiduciary for or of any Lender, or impose on Agent any duties or obligations other than those for which express provision is made herein. In performing its express duties and obligations hereunder, Agent shall have no liability to any Lender in the absence of gross negligence or willful misconduct by Agent. Lenders expressly acknowledge and agree that Agent shall have no implied duties hereunder including, without limitation, any implied duty of good faith and fair dealing. Agent agrees that, upon the request of any Lender, it will use its best efforts to obtain any information from or with respect to Borrower that is available to Agent pursuant to the terms of this Agreement. 9.02 Payments and Distributions. Each Lender hereby authorizes Agent to receive any and all payments which are or which may become due under this Agreement, the Notes or any of the other Loan Documents. Each Lender and Agent hereby authorize and instruct Borrower to make all payments which are or which may become due under any of such Loan Documents directly to Agent. Each Lender hereby agrees that, in the event it receives any payment which should have been made to Agent pursuant to the terms of this Agreement, or in the event it offsets any amounts placed on deposit with it by Borrower, it shall immediately remit such payment or offset amount to Agent for distribution in accordance with the terms of this Agreement. Except as otherwise expressly provided herein, Agent shall distribute promptly to Lenders all sums received by Agent as a payment on or related to any of the Loan Documents ratably in proportion to the amount of each Lender's interest in the Loans listed on Schedule 1 hereto. In the event interest on any of the Notes accrues at more than one rate, or Agent receives any prepayment with respect to any Note, all interest payments and all prepayments received by Agent hereunder shall be distributed ratably among Lenders in proportion to the amount of each Lender's interest in the Loans, regardless of whether the interest or prepayment was purported to have been made with respect to less than all of the Notes. 9.03 Notices. Agent will promptly advise each Lender of any actual notice of a default of Borrower hereunder received by Agent. Agent shall not be under any obligation to any Lender to ascertain or inquire as to the performance or observance of any of the terms or conditions of this Agreement or any other Loan Document to be performed or observed by Borrower. Each Lender hereby agrees that it will, promptly upon receipt of actual notice thereof, notify Agent of the existence of any default of Borrower hereunder. 9.04 Indemnity. Each Lender hereby agrees to, and shall, ratably in proportion to the amount of each Lender's interest in the Loans, indemnify, to the extent not reimbursed by Borrower, Agent against any loss, expense (including legal fees) or liability (except such as results from Agent's own gross negligence or willful misconduct) which Agent may suffer or 35 36 incur in connection with the implementation, administration or enforcement of the Loans or any of the Loan Documents. 9.05 Reliance. In performing its duties and exercising its powers hereunder, Agent will be entitled to rely on (a) any communication believed by it to be genuine and to have been sent or signed by the person by whom it purports to have been sent or signed and (b) the opinions and statements of any professional advisor selected by it in connection herewith, and Agent shall not be liable to any other party hereto for any consequence of any such reliance. 9.06 Truth of Representations. Agent takes no responsibility for the truth of any representations made herein, nor for the adequacy or enforceability of this Agreement, and neither Agent (except in the case of its gross negligence or willful misconduct) nor any of its officers, directors, employees, agents or representatives shall be liable for any action taken or omitted to be taken by it or any of them under or pursuant to this Agreement, or for any oversight or error of judgment. 9.07 Business with Borrower. Notwithstanding the agency herein constituted, Bank One, in its individual capacity, may, without liability to account, make loans to, accept deposits from and generally engage in any kind of banking or trust business with Borrower. Lenders expressly acknowledge and agree that such activities shall not constitute (and shall not be construed to constitute) a conflict of interest with Agent's performance of its duties hereunder. 9.08 Independent Investigations. Each Lender acknowledges that it has taken and will take such independent action and make such investigations as it deems necessary to inform itself as to the financial condition and affairs of Borrower and, based upon such independent action and investigation, it has determined to enter into this Agreement. 9.09 Prior Adjudication of Certain Actions. If, in the opinion of Agent, the distribution of any sum received by Agent in such capacity hereunder, under the Notes or under any other Loan Document, or the taking or omitting to take of any action hereunder or thereunder, might involve Agent in liability, it may refrain from taking such action (or omitting to take such action) until its right to take such action (or omit to take such action) shall have been adjudicated by a court of competent jurisdiction. If a court of competent jurisdiction shall adjudge that any amount received and distributed by Agent is to be paid to a person other than the recipient thereof, each Lender or other person to whom any such distribution shall have been made shall either repay to Agent its proportionate share of the amount so adjudged to be repaid or shall pay over the same in such a manner and to such persons as shall be determined by such court. 9.10 Remedies upon Default. Upon the occurrence of an event of default hereunder by Borrower, the Lenders shall mutually agree upon which remedies will be pursued with respect to the Loans and the collateral securing the same (including, without limitation, deeds or assignments in lieu of any such proceedings). The Lenders shall mutually agree upon which method of disposition of any collateral securing the Loans, or may elect to not pursue any or all remedies with respect to such collateral. Should such proceedings result in the foreclosure of any security interest held by Agent or Lenders, Agent shall have the right to acquire such 36 37 collateral at foreclosure, and to bid therefor all or any portion of the indebtedness of Borrower to Lenders under the Loans and, if the successful bidder thereon, Agent shall acquire such collateral as nominee for Lenders and operate and/or dispose of such collateral in the manner in which the Lenders mutually agree, all expenses of operation and disposal of such collateral to be borne by Lenders ratably according to their respective interests in the Loans. In addition to the foregoing, upon the occurrence of an event of default hereunder by Borrower (or, if in the opinion of Lenders, such a default seems imminent), Lenders, subject to the provisions of Section 9.13 hereof shall be entitled, should they so elect, to pursue any restructuring or modification of the terms and provisions (including, without limitation, repayment provisions) of the Loans, the Notes, this Agreement and the other Loan Documents. Each Lender hereby agrees to, and shall, ratably in proportion to the amount of each Lender's interest in the Loans, indemnify and hold Agent harmless from and against any and all loss, liability or expense (except such as results from Agent's own gross negligence or willful misconduct) incurred by Agent in connection with its actions taken hereunder, or in connection with any related document, after the occurrence of an event of default hereunder by Borrower (including, without limitation, actions taken to foreclose on, operate or dispose of any collateral and/or to restructure the terms and provisions of the Loans, subject in all respects to Agent's compliance with this Section 9.10). 9.11 Fundings by Lenders. Agent shall notify Lenders by telephone or telecopy as promptly as practicable of a request for advance by Borrower and the date on which such advance is requested to be made. Each Lender hereby agrees to deposit with Agent, prior to 2:00 p.m. Houston time on the date such advance is requested to be made, such Lender's portion of such advance, which shall be determined by the percentage interest of such Lender in the Loans. 9.12 Default by a Lender. In the event any Lender fails to timely make available to Agent such Lender's pro rata portion of any loan made or to be made pursuant to this Agreement or any other amount due from such Lender to Agent hereunder or under any of the other Loan Documents, or upon the breach by any Lender of any of its other obligations hereunder, such defaulting Lender shall be referred to as a "Defaulting Lender" and Agent and other Lenders shall have the rights described in this Section with respect to such Defaulting Lender. Any amounts received by Agent or any Lender (including the Defaulting Lender) after the default causing such Lender to become a Defaulting Lender shall be paid to Agent or Lenders other than the Defaulting Lender (the "Non-defaulting Lenders," whether one or more) in such proportion as the interest of each Non-defaulting Lender bears to the interest in the Loans of all Non-defaulting Lenders. Further, Agent and the Non-defaulting Lenders shall have the right but not the obligation, to advance monies on behalf of, or otherwise cure defaults of, the Defaulting Lender, and the Defaulting Lender shall be liable to each such party for all amounts so expended, such amounts to be repaid either through funds received or to be received by Agent or the other Lenders as a payment on the Notes or other indebtedness hereunder, or otherwise through the general funds of such Defaulting Lender. For so long as any Lender is a Defaulting Lender, such Lender shall be deemed to have transferred and assigned to the Non-defaulting Lenders all right, title and interest of such Defaulting Lender in and to the Loans, this Agreement, the Notes, and the other Loan Documents, as security for the payment of all amounts owing from such Defaulting Lender to the Non-defaulting Lenders or that may be advanced by the Non-defaulting Lenders to or for the benefit of Borrower on behalf of such Defaulting Lender. Once all obligations of the Defaulting Lender to Agent and the other Lenders have been satisfied, so that 37 38 no default by such Lender exists hereunder, (1) the Non-defaulting Lenders shall be deemed to have transferred and reassigned to such Lender the right, title and interest of such Lender in and to the Loans previously transferred and assigned as security to the Non-defaulting Lenders, (2) such Lender shall be entitled to be reinstated as a Lender hereunder and (3) subject to the continued compliance with the terms hereof, such Lender shall thereafter be entitled to receive all amounts payable with respect to its interest in the Loans. 9.13 Actions Requiring Consent of Lenders. (a) Except as set forth in Section 9.10 and this Section 9.13, Agent shall be entitled to take all action and exercise all powers relating to the Loans, the Loan Documents, and Lenders' rights and obligations thereunder. (b) Agent is not authorized to, and shall not, undertake any of the following actions without the written consent of all Lenders: (1) change the maximum availability hereunder; (2) change the fees or rate of interest payable with respect to the Loans; (3) change the date on which any payment on the Loans is due or extend the final maturity date of any Note; (4) waive any payment default under any Note; (5) release any collateral securing the Loans; (6) release Borrower or any Guarantor from liability on the Loans; (7) accelerate the maturity of the Notes; (8) waive compliance by Borrower with, amend or modify the terms of Section 8, or any covenant set forth in Section 6 or any covenant set forth in Section 7 hereof; or (9) amend or modify Section 9.10, or 9.12 or this Section 9.13(b). (c) No Lender shall be entitled to take any action with respect to the obligations owed to it under any Note, any Guaranty or any other Loan Document including, without limitation, acceleration of the maturity of such Lender's Note, it being agreed that all of such actions shall be taken by Agent in the manner prescribed in this Agreement. 38 39 9.14 Resignation; Successor Agent. Agent may resign at any time from the agency created hereby by giving written notice of such resignation to Borrower and Lenders, and Agent shall be relieved of all duties and obligations arising hereunder after the time of such resignation. Upon receipt of notice of such resignation, Lenders shall mutually agree upon the appointment of a successor agent hereunder or, if Lenders fail to so appoint a successor agent within thirty (30) days after receipt of notice of the resignation of Agent, any Lender may petition a court of competent jurisdiction to appoint a successor agent hereunder. Upon appointment and acceptance of the agency created hereby by the successor agent, such successor agent shall succeed to all the rights, duties and obligations of Agent hereunder. In the event Agent is placed under receivership or is subject to any supervisory order or proceeding initiated by applicable regulatory authority, such event shall be deemed a resignation by Agent pursuant to the terms of this Agreement. 9.15 No Third Party Beneficiary. Nothing in this Section 9, express or implied, is intended or shall be construed to give to any person other than Lenders and Agent (including, without limitation, Borrower) any right or remedy, and all terms and provisions of this Section 9 shall be for the sole benefit of Lenders and Agent. SECTION 10. MISCELLANEOUS. 10.01 No Waiver. No waiver of any Default or Event of Default shall be a waiver of any other Default or Event of Default. No failure to exercise and no delay on the part of Lenders in exercising any power or right in connection herewith or under any of the other Loan Documents shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. No course of dealing between Borrower or any other Person and Lenders shall operate as a waiver of any rights of Lenders. No amendment, modification or waiver of any portion of this Agreement or any other Loan Document nor consent to any departure therefrom shall in any event be effective unless the same shall be in writing and signed by the Person against whom enforcement thereof is to be sought, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on Borrower or any other Person in any case shall entitle Borrower or any other Person to any other or further notice or demand in similar or other circumstances. 10.02 Notices. Notices under the Loan Documents shall be in writing and shall be (i) delivered; (ii) mailed by registered or certified mail, return receipt requested, postage prepaid, or (iii) sent by telex, telecopy, telegram, or other form of electronic transmission, in each case to the address or telecopy number asset forth on the signature page hereof, or to such other address or telecopy number as party may by written notice designate. Notices shall be deemed to have been given to Borrower when received by Borrower and shall be deemed to have been given to Lenders when received by Agent. 10.03 Set-Off. If one or more Events of Default shall occur and be continuing, the holder of the Notes shall have the right without notice to Borrower and to the fullest extent permitted by applicable law, in addition to all other rights and remedies available to it, to set-off 39 40 against the unpaid balance of the indebtedness owing to it, on account of the Loans or otherwise, in such order as such holder may in its sole discretion decide, any obligations owing to Borrower by such holder, irrespective of whether Lenders shall have made any demand for satisfaction of such obligations and although such obligations may be unmatured, including, without limitation, any funds in any deposit account maintained by Borrower with such holder, and nothing in this Agreement shall be deemed a waiver or prohibition of Lenders' rights of banker's lien or set-off. 10.04 GOVERNING LAW. THE LOAN DOCUMENTS ARE BEING DELIVERED AND ARE INTENDED TO BE PERFORMED IN THE STATE OF TEXAS. UNLESS OTHERWISE SPECIFIED THEREIN, EACH LOAN SHALL BE DEEMED TO BE A CONTRACT UNDER THE LAWS OF THE STATE OF TEXAS AND FOR ALL PURPOSES SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS, AND WHENEVER REQUIRED, THE FEDERAL LAWS OF THE UNITED STATES OF AMERICA. 10.05 Survival of Warranties; Successors and Assigns. All representations, warranties and covenants made by Borrower in connection herewith shall survive the execution and delivery of the Loan Documents, shall not be affected by any investigation made by any Person and shall bind Borrower and its respective successors, trustees, receivers and assigns and inure to the benefit of the successors and assigns of Lenders, provided that the undertaking of Lenders hereunder to make the Loans to Borrower shall not inure to the benefit of any successor or assign of Borrower. The term of this Agreement shall be until the payment in full of the Notes and the Obligations. 10.06 Counterparts. This Agreement may be executed in several identical counterparts, and by the parties hereto on separate counterparts, and each counterpart, when so executed and delivered, shall constitute an original instrument, and all such separate counterparts shall constitute but one and the same instrument. 10.07 Maximum Interest Rate. It is the intention of the parties hereto to comply with the usury laws of the state of Texas and the United States; accordingly, it is agreed that notwithstanding any provision to the contrary in the Notes, or in any of the Loan Documents or otherwise relating to this Agreement, no such provision shall require the payment or permit the collection of interest in excess of the maximum permitted by applicable state or Federal law. If any excess of interest in such respect is provided for, or shall be adjudicated to be so provided for, in the Notes or in any of the Loan Documents or otherwise relating to this Agreement, or in the event the maturity of the indebtedness evidenced by the Notes is accelerated in whole or in part, or in the event that all or part of the principal or interest of the Notes shall be prepaid, so that under any of such circumstances the amount of interest contracted for, charged or received under the Notes or under any of the Loan Documents or otherwise relating hereto, on the amount of principal actually outstanding from time to time under the Notes shall exceed the maximum amount of interest permitted by the usury laws of the state of Texas and the United States, then, in any such event, (a) the provisions of this paragraph shall govern and control, (b) neither Borrower hereof nor successors or assigns or any other party liable for the payment hereof shall be obligated to pay the amount of such interest to the extent that it is in excess of the maximum amount permitted by applicable state or Federal law, (c) any such excess which may have been 40 41 collected shall be, at the holder's option (at maturity or in the Event of Default hereunder), either applied as a credit against the then unpaid principal amount thereof or refunded to Borrower, and (d) the effective rate of interest shall be automatically subject to reduction to the maximum lawful contract rate allowed under the usury laws of the state of Texas or the United States as now or hereafter construed by the courts having jurisdiction. 10.08 Exhibits, etc. The exhibits, schedules and annexes attached to or delivered in connection with this Agreement are incorporated herein and shall be considered a part of this Agreement for all purposes, except that in the event of conflict between any of the provisions of such exhibits, schedules and annexes and the provisions of this Agreement, this Agreement shall control. 10.09 References and Captions.
