The Estimated Cash Amount shall be paid in cash by wire transfer of immediately available funds to the account of the Holder Representative. Adjustments to Purchase Price.

As soon as practicable, but in no event later than ninety (90) days after the Closing, the Holders shall cause to be prepared and delivered to Buyer the Closing Date Balance Sheet which shall reflect the Net Current Assets as of the close of business on the Closing Date (the "Actual Net Current Assets"). The Closing Date Balance Sheet and the Actual Net Current Assets reflected thereon shall be determined in accordance and consistently with the Agreed Procedure, and the Closing Date Balance Sheet shall be accompanied by an audit opinion thereon of the independent auditor for The Hake Group of Companies, Rainer & Company ("Rainer") to the effect that such Closing Date Balance Sheet and the Actual Net Current Assets reflected thereon were prepared in accordance with GAAP (based on the rules of GAAP in effect at the time the Acquisition Date Balance Sheet was prepared, without regard to any changes in GAAP made or taking effect after such time ("Balance Sheet GAAP")) and with additional schedules showing adjustments required by the Agreed Procedure. After the Closing, Buyer shall make available to the Holders and Rainer, at no expense to the Holders, such of the facilities, books, records and personnel of Buyer as are reasonably requested by the Holders and Rainer in connection with the preparation of the Closing Date Balance Sheet and the Actual Net Current Assets. The Holders and Rainer shall make available to Buyer and its independent auditor, at no expense to Buyer, copies of all work papers, books and records used in the preparation and audit of the Closing Date Balance Sheet. In the event Buyer disputes that the Actual Net Current Assets reflected thereon were determined in accordance with the Agreed Procedure, Buyer shall, within thirty days after delivery of the Closing Date Balance Sheet, deliver a notice to the Holder Representative (the "Dispute Notice") setting forth in reasonable detail the basis of such dispute. If the Dispute Notice is not delivered within such thirty day period, then the Closing Date Balance Sheet and the Actual Net Current Assets reflected on the Closing Date Balance Sheet, as so determined by - -4-

the Holder Representative and Rainer, shall be the "Final Net Current Assets". In the event that the Dispute Notice is delivered within such period, Buyer and the Holder Representative shall have a period of 20 days to resolve such dispute by mutual agreement. If Buyer and the Holder Representative are able to resolve their dispute by mutual agreement, the "Final Net Current Assets" shall be the amounts agreed to by the parties. In the event Buyer and the Holder Representative are unable to resolve their dispute within such 20 day period, upon demand of either Buyer or the Holder Representative at any time during a 45 day period thereafter, the parties shall refer such dispute to the Philadelphia, Pennsylvania office of PricewaterhouseCoopers LLP who shall act as the Reviewing Accountant to review the portions of the Actual Net Current Assets which are subject to dispute. The parties shall, and shall instruct their respective accountants to, make available to the Reviewing Accountant all work papers and all other information and material in their possession as is requested by the Reviewing Accountant that relates to the items of Actual Net Current Assets in dispute. The Reviewing Accountant shall be instructed by the parties to use its best efforts to deliver its determination to the parties as promptly as practicable after submission of the dispute to the Reviewing Accountant. The determination of the Reviewing Accountant shall be final and binding on the parties (absent manifest error); and the Actual Net Current Assets reflected on the Closing Date Balance Sheet as determined by the Holder Representative and as modified (if at all) by agreement of Buyer and the Holder Representative or by the Reviewing Accountant in accordance with this Section 2.03A. shall be the "Final Net Current Assets". Each party shall bear its own expenses and the fees and expenses of its own representatives and experts, including its independent accountants, in connection with the preparation, review, dispute (if any) and final determination of the Final Net Current Assets. The parties shall share the costs, expenses and fees of the Reviewing Accountant in inverse proportion to the extent to which their respective' positions are sustained to a maximum of 100% for such party. For example, if the Holders assert that the dollar amount of inventories, if any, should be $1,000,000 and Buyer asserts it should be $800,000, and the Reviewing Accountant determines it to be $950,000, then the Holder's position would have been 75% sustained (i.e., 75% of the $200,000 in dispute was resolved in favor of the Holder's position) and the Holders would bear 25% and the Buyer would bear 75% (i.e., an inverse proportion) of the costs, expenses and fees of the Reviewing Accountant. Within ten days of the first to occur of (x) the expiration of the thirty day period from the delivery by the Holder Representative to Buyer of the Closing Date Balance Sheet and during which thirty day period Buyer does not deliver the Dispute Notice to the Holder Representative hereunder; or (y) the resolution by mutual agreement of Buyer and the Holder Representative of all disputes regarding the Actual Net Current Assets; or (z) the delivery by the Reviewing Accountant of its determination as to all portions of the Actual Net Current Assets in dispute, if the Final Net Current Assets exceeds $13,016,000 (the "Final Positive Adjustment"), then Buyer shall pay to the Holder Representative the amount by which the Final Positive Adjustment exceeds $3,751,818 which amount shall be treated as an adjustment to the Purchase Price, such amount to be paid 47% as a credit in connection with the amounts paid to MEP Participants pursuant to Section0B. hereof with the balance paid in cash within five (5) days after such determination; and - -5-

the Holders shall pay to Buyer the amount by which $3,751,818 exceeds the Final Positive Adjustment within five (5) days after such determination, which amount shall be treated as an adjustment to the Purchase Price. if the Final Net Current Assets are less than $13,016,000, Holders shall pay to Buyer an amount equal to the sum of (x) the amount of such shortfall, plus (y) the amount of the Final Positive Adjustment, which amount shall be treated as an adjustment to the Purchase Price. Adjustments for Approved Capital Expenditures. Since the date of the Acquisition Date Balance Sheet and prior to the date of execution of this Agreement, The Hake Group of Companies have made certain capital expenditures, which aggregate $650,000, that the Buyer has agreed shall be added to the Cash Amount as an adjustment to the Purchase Price. Such capital expenditures for which Buyer has agreed to increase the Cash Amount total $650,000 are set forth on Schedule 2.03B. hereto under the caption "Approved Capital Expenditure Amounts." The Approved Capital Expenditure Amounts shall be paid by Buyer to the Holder Representative for the benefit of the Holders at Closing. Such payment shall be treated as an adjustment to the Purchase Price. Adjustments to Deferred Portion of Purchase Price. Sections 12.02 and 12.03 of this Agreement sets forth the terms and conditions upon which the Parties have agreed to indemnify one another for certain breaches of representations, warranties and covenants made in this Agreement. In the case of the Holders, certain payments of indemnity are reflected as a decrease in the amount of the Deferred Portion of the Purchase Price and therefore as an adjustment to the Purchase Price. MEP Payments. At Closing, Hake Group, Inc. shall pay to the Holder Representative on behalf of the participants (the "MEP Participants") of the Management Equity Plan (the "MEP") the sum of $13,282,903 to be allocable to each participant in the pre-tax withholding percentage shown opposite the MEP Participant's name on Exhibit D. If a payment is due to the Holder Representative pursuant to Section 2.04A of this Agreement, the amount otherwise due to the Holder Representative on behalf of the Holders shall be reduced by forty-seven percent (47%) and the amount of such reduction shall (subject to applicable withholding) be paid to the Holder Representative for the benefit of the MEP Participants, in the pre-tax withholding percentage set forth opposite the MEP Participant's name on Exhibit D at the same time and in the same manner as the payment is made to the Holder Representative under Section 2.04A. Initial Fees. At Closing, the Hake Group, Inc. will pay to the entities identified on Schedule 2.02A the Initial Fees in immediately available funds. RETAINED LIABILITIES Retained Liabilities. At or prior to the Closing, The Hake Group of Companies shall each execute and deliver to the entities identified on Schedule 3.01 with respect their respective Retained Liabilities (the "RL Transferee(s)") an Assignment & Assumption Agreement in a form reasonably satisfactory to the Parties (the "Retained Liabilities Assignment & Assumption Agreement"), pursuant to which each of The Hake Group of Companies shall convey, assign and - -6-

transfer to the RL Transferees, and such RL Transferees shall assume and undertake to pay, perform and discharge, any and all Retained Liabilities effective as of the Closing.

In any case where Legal Requirements do not permit a member of The Hake Group of Companies to close its taxable year on the Closing Date or in any case in which a Tax is assessed with respect to a taxable period which includes the Closing Date (but does not begin or end on that day), then Taxes, if any, attributable to the taxable period of The Hake Group of Companies beginning before and ending after the Closing Date shall be allocated (i) to the Holders for the period up to and including the Closing Date (other than for items that occur after Closing), and (ii) to Matrix for the period subsequent to the Closing Date .

The failure of a party to timely forward such notification in accordance with the immediately preceding sentence shall not relieve the other Party or its Affiliate of its obligation to pay such liability for Taxes except and to the extent that the failure to timely forward such notification actually prejudices the ability of the other Party or such Affiliate to contest such liability for Taxes or increases the amount of such Taxes. Representation of Holders. The Holder Representative shall have the right to represent the interests of The Hake Group of Companies in any Tax audit or administrative or court proceeding relating to taxable periods ending on or prior to the Closing Date and to employ counsel of its choice at its expense, and Matrix shall have the right to consult with the Holder Representative during such proceedings at its own expense.

authority in such claim or assessment if such claim or assessment were sustained in its entirety.

The notice contemplated herein shall describe the Claim and the specific facts and circumstances in reasonable detail, shall include a copy of any related notices or written claims - -58-

from third-parties, and shall indicate the amount, if known, or an estimate, if possible, of the Damages that have been or may be suffered or incurred. Assumption of Defense. If any Claim is brought against a Matrix Indemnitee or a Holder Indemnitee and the Claiming Party gives notice to the Indemnifying Party of such Claim, the Indemnifying Party will, unless the Claim involves Taxes (which shall be resolved in accordance with the procedures in 0), be entitled to participate in such Claim and, to the extent that it wishes (unless (i) such Indemnifying Party is also a party to such Claim and the Claiming Party determines in good faith that joint representation would be inappropriate, or (ii) the Indemnifying Party fails to provide reasonable assurance to the Claiming Party of its financial capacity to defend such Claim and provide indemnification with respect to such Claim), to assume the defense of such Claim with counsel reasonably satisfactory to the Claiming Party and, after notice from the Indemnifying Party to the Claiming Party of its election to assume the defense of such Claim, the Indemnifying Party will not, as long as it diligently conducts such defense, be liable to the Claiming Party or the other relevant Holder Indemnitee(s) or Matrix Indemnitee(s) (as applicable) under this Section0for any fees of other counsel or any other expenses with respect to the defense of such Claim, in each case subsequently incurred by the Claiming Party or the other relevant Holder Indemnitee(s) or Matrix Indemnitee(s) (as applicable) in connection with the defense of such Claim, other than their reasonable costs of investigation. If the Indemnifying Party assumes the defense of a Claim, (i) it will be conclusively established for purposes of this Agreement that the Claim (and any resulting Damages) are within the scope of and subject to indemnification by the Indemnifying Party; (ii) no compromise or settlement of such claims may be effected by the Indemnifying Party without the Claiming Party's consent unless (A) there is no finding or admission of any violation of Legal Requirements or any violation of the rights of any Person and no effect on any other Claims that may be made against the Claiming Party or any other Holder Indemnitee or Matrix Indemnitee (as applicable), and (B) the sole relief provided is monetary damages that are paid in full by the Indemnifying Party; and (iii) the Claiming Party and each relevant Holder Indemnitee or Matrix Indemnitee (as applicable) will have no liability with respect to any compromise or settlement of such Claims effected without its consent. The Claiming Party and any relevant Holder Indemnitee or Matrix Indemnitee shall be entitled to participate (at its expense) in the defense of any Claim assumed by the Indemnifying Party as contemplated herein. If notice is given to an Indemnifying Party of any Claim and the Indemnifying Party does not, within ten days after the Claiming Party's notice is given, give notice to the Claiming Party of its election to assume the defense of such Claim, the Indemnifying Party will no longer have the right to assume that defense, and will be bound by any determination made in such Claim or any compromise or settlement effected by the Claiming Party or any other Holder Indemnitee or Matrix Indemnitee (as applicable). Exception. Notwithstanding the foregoing, if a Claiming Party or any other Holder Indemnitee or Matrix Indemnitee (as applicable), determines in good faith that there is a reasonable probability a Claim (other than a claim arising under Section 12.02(c) hereof) may adversely affect it or its Affiliates other than as a result of monetary damages for which it would be entitled to indemnification under this Agreement, that party or Person may, by notice to the Indemnifying Party, assume the exclusive right to defend, compromise or settle such Claim, but the Indemnifying Party will not be bound by any determination of a Claim so defended or any compromise or settlement effected without its consent (which may not be unreasonably withheld). Other Claims. A claim for indemnification for any matter not involving a third-party Claim may be asserted by notice to the Party from whom indemnification is sought. Cooperation of Parties. The Party assuming the defense of any Claim shall keep the other Party(s) reasonably informed at all times of the progress and development of the Party's defense of and - -59-

compromise efforts with respect to such Claim, and shall furnish the other Party(s) with copies of all relevant pleadings, correspondence and other papers. In addition, the Parties to this Agreement shall cooperate with each other, and make available to each other and their representatives all available relevant records or other materials required by them for their use in defending, compromising or contesting any Claim. No Liability of The Hake Group of Companies. In the event a Claim is made against the Holders for any Damages incurred by Buyer or Matrix, the Holders shall not, nor shall they be entitled to, maintain, assert or make a claim against any member of The Hake Group of Companies, or the directors or officers of each, for contribution, indemnity or any other recovery, it being the intention of the Parties hereto that after the Closing The Hake Group of Companies shall have no liability, obligation or responsibility to the Holders for any breach or nonfulfillment of the representations, warranties, covenants or obligations of Buyer and Matrix made in this Agreement.

Discovery. The Parties shall have the right of discovery in accordance with the Federal Rules of Civil Procedure except that discovery may commence immediately upon the service of the demand for arbitration. A Party's unreasonable refusal to cooperate in discovery shall be deemed to be refusal to proceed with arbitration and, until AAA has designated the arbitrator, the Parties may enforce their rights (including the right of discovery) in the courts. Such enforcement in the courts shall not constitute a waiver of a Party's right to arbitration. Upon his or her appointment, the arbitrator shall have the power to enforce the Parties' discovery rights. Binding Decision. The Parties shall be bound by the decision of the arbitrator and accept his or her decision as the final determination of the matter in dispute.

In the event that the amount subject to the Claim is unliquidated, Buyer shall have made a good faith estimate as to the amount of the Claim that is included in the Notice of Claim.

(iii) The entries maintained in the accounts maintained pursuant to paragraphs (i) and (ii) above shall be prima facie evidence of the existence and amounts of the Obligations therein recorded; provided, however, that the failure of the Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms. (iv) Any Lender may request that its Loans be evidenced by a promissory note, substantially in the form of Exhibits "E-1", "E-2", or "E-3" (each a "Note"). In such event, the 25

Borrower shall prepare, execute and deliver to such Lender such Note or Notes payable to the order of such Lender. Thereafter, the Loans evidenced by each such Note and interest thereon shall at all times (prior to any assignment pursuant to Section 12.3) be represented by one or more Notes payable to the order of the payee named therein, except to the extent that any such Lender subsequently returns any such Note for cancellation and requests that such Loans once again be evidenced as described in paragraphs (i) and (ii) above. 2.14. Telephonic Notices. The Borrower hereby authorizes the Lenders and the Agent to extend, convert or continue Advances, effect selections of Types of Advances and to transfer funds based on telephonic notices made by any person or persons the Agent or any Lender in good faith believes to be acting on behalf of the Borrower, it being understood that the foregoing authorization is specifically intended to allow Borrowing Notices and Conversion/Continuation Notices to be given telephonically. The Borrower agrees to deliver promptly to the Agent a written confirmation, if such confirmation is requested by the Agent or any Lender, of each telephonic notice signed by an Authorized Officer. If the written confirmation differs in any material respect from the action taken by the Agent and the Lenders, the records of the Agent and the Lenders shall govern absent manifest error. 2.15. Interest Payment Dates; Interest and Fee Basis. Interest accrued on each Floating Rate Advance shall be payable on each Payment Date, commencing with the first such date to occur after the date hereof, on any date on which the Floating Rate Advance is prepaid, whether due to acceleration or otherwise, and at maturity. Interest accrued on that portion of the outstanding principal amount of any Floating Rate Advance converted into a Eurodollar Advance on a day other than a Payment Date shall be payable on the date of conversion. Interest accrued on each Eurodollar Advance shall be payable on the last day of its applicable Interest Period, on any date on which the Eurodollar Advance is prepaid, whether by acceleration or otherwise, and at maturity. Interest accrued on each Eurodollar Advance having an Interest Period longer than three months shall also be payable on the last day of each three-month interval during such Interest Period. Interest, commitment fees and LC Fees shall be calculated for actual days elapsed on the basis of a 360-day year. Interest shall be payable for the day an Advance is made but not for the day of any payment on the amount paid if payment is received prior to noon (local time) at the place of payment. If any payment of principal of or interest on an Advance shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of a principal payment, such extension of time shall be included in computing interest in connection with such payment. 2.16. Notification of Advances, Interest Rates, Prepayments and Commitment Reductions. Promptly after receipt thereof, the Agent will notify each Lender of the contents of each Aggregate Commitment reduction notice, Borrowing Notice, Swing Line Borrowing Notice, Conversion/Continuation Notice, and repayment notice received by it hereunder. Promptly after notice from the LC Issuer, the Agent will notify each Lender of the contents of each request for issuance of a Facility LC hereunder. The Agent will notify each Lender of the interest rate applicable to each Eurodollar Advance promptly upon determination of such interest rate and will give each Lender prompt notice of each change in the Alternate Base Rate. 26

2.17. Lending Installations. Each Lender may book its Loans and its participation in any LC Obligations and the LC Issuer may book the Facility LCs at any Lending Installation selected by such Lender or the LC Issuer, as the case may be, and may change its Lending Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation and the Loans, Facility LCs, participations in LC Obligations and any Notes issued hereunder shall be deemed held by each Lender or the LC Issuer, as the case may be, for the benefit of any such Lending Installation. Each Lender and the LC Issuer may, by written notice to the Agent and the Borrower in accordance with Article XIII, designate replacement or additional Lending Installations through which Loans will be made by it or Facility LCs will be issued by it and for whose account Loan payments or payments with respect to Facility LCs are to be made. 2.18. Non-Receipt of Funds by the Agent. Unless the Borrower or a Lender, as the case may be, notifies the Agent prior to the date on which it is scheduled to make payment to the Agent of (i) in the case of a Lender, the proceeds of a Loan or (ii) in the case of the Borrower, a payment of principal, interest or fees to the Agent for the account of the Lenders, that it does not intend to make such payment, the Agent may assume that such payment has been made. The Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption. If such Lender or the Borrower, as the case may be, has not in fact made such payment to the Agent, the recipient of such payment shall, on demand by the Agent, repay to the Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Agent until the date the Agent recovers such amount at a rate per annum equal to (x) in the case of payment by a Lender, the Federal Funds Effective Rate for such day for the first three days and, thereafter, the interest rate applicable to the relevant Loan or (y) in the case of payment by the Borrower, the interest rate applicable to the relevant Loan. 2.19. Facility LCs. 2.19.1. Issuance. The LC Issuer hereby agrees, on the terms and conditions set forth in this Agreement, to issue standby and commercial letters of credit (each, a "Facility LC") and to renew, extend, increase, decrease or otherwise modify each Facility LC ("Modify," and each such action a "Modification"), from time to time from and including the date of this Agreement and prior to the Facility Termination Date upon the request of the Borrower; provided that immediately after each such Facility LC is issued or Modified, (i) the aggregate amount of the outstanding LC Obligations shall not exceed $25,000,000 and (ii) the Aggregate Outstanding Credit Exposure shall not exceed the Aggregate Commitment. No Facility LC shall have an expiry date later than the earlier of (x) the fifth Business Day prior to the Facility Termination Date and (y) one year after its issuance, provided that Facility LC with a one (1) year expiration date may include renewals for additional one year periods, so long as it does not extend beyond (x). 2.19.2. Participations. Upon the issuance or Modification by the LC Issuer of a Facility LC in accordance with this Section 2.19, the LC Issuer shall be deemed, without further action by any party hereto, to 27

have unconditionally and irrevocably sold to each Lender, and each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from the LC Issuer, a participation in such Facility LC (and each Modification thereof) and the related LC Obligations in proportion to its Pro Rata Share. 2.19.3. Notice. Subject to Section 2.19.1, the Borrower shall give the LC Issuer notice prior to 10:00 a.m. (Tulsa time) at least five Business Days prior to the proposed date of issuance or Modification of each Facility LC, specifying the beneficiary, the proposed date of issuance (or Modification) and the expiry date of such Facility LC, and describing the proposed terms of such Facility LC and the nature of the transactions proposed to be supported thereby. Upon receipt of such notice, the LC Issuer shall promptly notify the Agent, and the Agent shall promptly notify each Lender, of the contents thereof and of the amount of such Lender's participation in such proposed Facility LC. The issuance or Modification by the LC Issuer of any Facility LC shall, in addition to the conditions precedent set forth in Article IV (the satisfaction of which the LC Issuer shall have no duty to ascertain), be subject to the conditions precedent that such Facility LC shall be satisfactory to the LC Issuer and that the Borrower shall have executed and delivered such application agreement and/or such other instruments and agreements relating to such Facility LC as the LC Issuer shall have reasonably requested (each, a "Facility LC Application"). In the event of any conflict between the terms of this Agreement and the terms of any Facility LC Application, the terms of this Agreement shall control. 2.19.4. LC Fees. The Borrower shall pay to the Agent, for the account of the Lenders ratably in accordance with their respective Pro Rata Shares, with respect to each Facility LC, a letter of credit fee at a per annum rate equal to the applicable percentage set forth on the Pricing Schedule on the average daily undrawn stated amount under such standby Facility LC, such fee to be payable in arrears on each Payment Date, (such fee described as the "LC Fee". The Borrower shall also pay to the LC Issuer for its own account (x) at the time of issuance of each Facility LC, a fronting fee equal to 0.125%, and (y) documentary and processing charges in connection with the issuance or Modification of and draws under Facility LCs in accordance with the LC Issuer's standard schedule for such charges as in effect from time to time. 2.19.5. Administration; Reimbursement by Lenders. Upon receipt from the beneficiary of any Facility LC of any demand for payment under such Facility LC, the LC Issuer shall notify the Agent and the Agent shall promptly notify the Borrower and each other Lender as to the amount to be paid by the LC Issuer as a result of such demand and the proposed payment date (the "LC Payment Date"). The responsibility of the LC Issuer to the Borrower and each Lender shall be only to determine that the documents (including each demand for payment) delivered under each Facility LC in connection with such presentment shall be in conformity in all material respects with such Facility LC. The LC Issuer shall endeavor to exercise the same care in the issuance and administration of the Facility LCs as it does with respect to letters of credit in which no participations are granted, it being understood that in the absence of any gross negligence or willful misconduct by the LC Issuer, each Lender shall be unconditionally and irrevocably liable without regard to the occurrence of any Default or any condition 28

precedent whatsoever, to reimburse the LC Issuer on demand for (i) such Lender's Pro Rata Share of the amount of each payment made by the LC Issuer under each Facility LC to the extent such amount is not reimbursed by the Borrower pursuant to Section 2.19.6 below, plus (ii) interest on the foregoing amount to be reimbursed by such Lender, for each day from the date of the LC Issuer's demand for such reimbursement (or, if such demand is made after 11:00 a.m. (Tulsa time) on such date, from the next succeeding Business Day) to the date on which such Lender pays the amount to be reimbursed by it, at a rate of interest per annum equal to the Federal Funds Effective Rate for the first three days and, thereafter, at a rate of interest equal to the rate applicable to Floating Rate Advances. 2.19.6. Reimbursement by Borrower. The Borrower shall be irrevocably and unconditionally obligated to reimburse the LC Issuer on or before the applicable LC Payment Date for any amounts to be paid by the LC Issuer upon any drawing under any Facility LC, without presentment, demand, protest or other formalities of any kind; provided that neither the Borrower nor any Lender shall hereby be precluded from asserting any claim for direct (but not consequential) damages suffered by the Borrower or such Lender to the extent, but only to the extent, caused by (i) the willful misconduct or gross negligence of the LC Issuer in determining whether a request presented under any Facility LC issued by it complied with the terms of such Facility LC or (ii) the LC Issuer's failure to pay under any Facility LC issued by it after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. All such amounts paid by the LC Issuer and remaining unpaid by the Borrower shall bear interest, payable on demand, for each day until paid at a rate per annum equal to (x) the rate applicable to Floating Rate Advances for such day if such day falls on or before the applicable LC Payment Date and (y) the sum of 2% plus the rate applicable to Floating Rate Advances for such day if such day falls after such LC Payment Date. The LC Issuer will pay to each Lender ratably in accordance with its Pro Rata Share all amounts received by it from the Borrower for application in payment, in whole or in part, of the Reimbursement Obligation in respect of any Facility LC issued by the LC Issuer, but only to the extent such Lender has made payment to the LC Issuer in respect of such Facility LC pursuant to Section 2.19.5. Subject to the terms and conditions of this Agreement (including without limitation the submission of a Borrowing Notice in compliance with Section 2.8 and the satisfaction of the applicable conditions precedent set forth in Article IV), the Borrower may request an Advance hereunder for the purpose of satisfying any Reimbursement Obligation. 2.19.7. Obligations Absolute. The Borrower's obligations under this Section 2.19 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which the Borrower may have or have had against the LC Issuer, any Lender or any beneficiary of a Facility LC. The Borrower further agrees with the LC Issuer and the Lenders that the LC Issuer and the Lenders shall not be responsible for, and the Borrower's Reimbursement Obligation in respect of any Facility LC shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, fraudulent or forged, or any dispute between or among 29

the Borrower, any of its Affiliates, the beneficiary of any Facility LC or any financing institution or other party to whom any Facility LC may be transferred or any claims or defenses whatsoever of the Borrower or of any of its Affiliates against the beneficiary of any Facility LC or any such transferee. The LC Issuer shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Facility LC. The Borrower agrees that any action taken or omitted by the LC Issuer or any Lender under or in connection with each Facility LC and the related drafts and documents, if done without gross negligence or willful misconduct, shall be binding upon the Borrower and shall not put the LC Issuer or any Lender under any liability to the Borrower. Nothing in this Section 2.19.7 is intended to limit the right of the Borrower to make a claim against the LC Issuer for damages as contemplated by the proviso to the first sentence of Section 2.19.6. 2.19.8. Actions of LC Issuer. The LC Issuer shall be entitled to rely, and shall be fully protected in relying, upon any Facility LC, draft, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by the LC Issuer. The LC Issuer shall be fully justified in failing or refusing to take any action under this Agreement unless it shall first have received such advice or concurrence of the Required Lenders as it reasonably deems appropriate or it shall first be indemnified to its reasonable satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Notwithstanding any other provision of this Section 2.19, the LC Issuer shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement in accordance with a request of the Required Lenders, and such request and any action taken or failure to act pursuant thereto shall be binding upon the Lenders and any future holders of a participation in any Facility LC. 2.19.9. Indemnification. The Borrower hereby agrees to indemnify and hold harmless each Lender, the LC Issuer and the Agent, and their respective directors, officers, agents and employees from and against any and all claims and damages, losses, liabilities, costs or expenses which such Lender, the LC Issuer or the Agent may incur (or which may be claimed against such Lender, the LC Issuer or the Agent by any Person whatsoever) by reason of or in connection with the issuance, execution and delivery or transfer of or payment or failure to pay under any Facility LC or any actual or proposed use of any Facility LC, including, without limitation, any claims, damages, losses, liabilities, costs or expenses which the LC Issuer may incur by reason of or in connection with (i) the failure of any other Lender to fulfill or comply with its obligations to the LC Issuer hereunder (but nothing herein contained shall affect any rights the Borrower may have against any defaulting Lender) or (ii) by reason of or on account of the LC Issuer issuing any Facility LC which specifies that the term "Beneficiary" included therein includes any successor by operation of law of the named Beneficiary, but which Facility LC does not require that any drawing by any such successor Beneficiary be accompanied by a copy of a legal document, satisfactory to the LC Issuer, evidencing the appointment 30

of such successor Beneficiary; provided that the Borrower shall not be required to indemnify any Lender, the LC Issuer or the Agent for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by (x) the willful misconduct or gross negligence of the LC Issuer in determining whether a request presented under any Facility LC complied with the terms of such Facility LC or (y) the LC Issuer's failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. Nothing in this Section 2.19.9 is intended to limit the obligations of the Borrower under any other provision of this Agreement. 2.19.10. Lenders' Indemnification. Each Lender shall, ratably in accordance with its Pro Rata Share, indemnify the LC Issuer, its affiliates and their respective directors, officers, agents and employees (to the extent not reimbursed by the Borrower) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such indemnitees' gross negligence or willful misconduct or the LC Issuer's failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of the Facility LC) that such indemnitees may suffer or incur in connection with this Section 2.19 or any action taken or omitted by such indemnitees hereunder. 2.19.11. Facility LC Collateral Account. The Borrower agrees that it will, upon the request of the Agent or the Required Lenders and until the final expiration date of any Facility LC and thereafter as long as any amount is payable to the LC Issuer or the Lenders in respect of any Facility LC, maintain a special collateral account pursuant to arrangements satisfactory to the Agent (the "Facility LC Collateral Account") at the Agent's office at the address specified pursuant to Article XIII, in the name of such Borrower but under the sole dominion and control of the Agent, for the benefit of the Lenders and in which such Borrower shall have no interest other than as set forth in Section 8.1. The Borrower hereby pledges, assigns and grants to the Agent, on behalf of and for the ratable benefit of the Lenders and the LC Issuer, a security interest in all of the Borrower's right, title and interest in and to all funds which may from time to time be on deposit in the Facility LC Collateral Account to secure the prompt and complete payment and performance of the Obligations. The Agent will invest any funds on deposit from time to time in the Facility LC Collateral Account in certificates of deposit of Bank One having a maturity not exceeding 30 days. Nothing in this Section 2.19.11 shall either obligate the Agent to require the Borrower to deposit any funds in the Facility LC Collateral Account or limit the right of the Agent to release any funds held in the Facility LC Collateral Account in each case other than as required by Section 8.1. 2.19.12. Rights as a Lender. In its capacity as a Lender, the LC Issuer shall have the same rights and obligations as any other Lender. 2.20. Swing Line Loans. 2.20.1. Amount of Swing Line Loans. Upon the satisfaction of the conditions precedent set forth in Section 4.2 and, if such Swing Line Loan is to be made on the date 31

of the initial Advance hereunder, the satisfaction of the conditions precedent set forth in Section 4.1 as well, from and including the date of this Agreement and prior to the Facility Termination Date, the Swing Line Lender agrees, on the terms and conditions set forth in this Agreement, to make Swing Line Loans to the Borrower from time to time in an aggregate principal amount not to exceed the Swing Line Commitment, provided that the Aggregate Outstanding Credit Exposure shall not at any time exceed the Aggregate Commitment, and provided further that at no time shall the sum of (i) the Swing Line Lender's Pro Rata Share of the Swing Line Loans, plus (ii) the outstanding Revolving Loans made by the Swing Line Lender pursuant to Section 2.1, exceed the Swing Line Lender's Commitment at such time. Subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow Swing Line Loans at any time prior to the Facility Termination Date. 2.20.2. Borrowing Notice. The Borrower shall deliver to the Agent and the Swing Line Lender irrevocable notice (a "Swing Line Borrowing Notice") not later than noon (Tulsa time) on the Borrowing Date of each Swing Line Loan, specifying (i) the applicable Borrowing Date (which date shall be a Business Day), and (ii) the aggregate amount of the requested Swing Line Loan which shall be an amount not less than $100,000. The Swing Line Loans shall bear interest at the Floating Rate. 2.20.3. Making of Swing Line Loans. Promptly after receipt of a Swing Line Borrowing Notice, the Agent shall notify each Lender by fax, or other similar form of transmission, of the requested Swing Line Loan. Not later than 2:00 p.m. (Tulsa time) on the applicable Borrowing Date, the Swing Line Lender shall make available the Swing Line Loan, in funds immediately available in Tulsa, to the Agent at its address specified pursuant to Article XIII. The Agent will promptly make the funds so received from the Swing Line Lender available to the Borrower on the Borrowing Date at the Agent's aforesaid address. 2.20.4. Repayment of Swing Line Loans. Each Swing Line Loan shall be paid in full by the Borrower on or before the fifth (5th) Business Day after the Borrowing Date for such Swing Line Loan. In addition, the Swing Line Lender (i) may at any time in its sole discretion with respect to any outstanding Swing Line Loan, or (ii) shall on the fifth (5th) Business Day after the Borrowing Date of any Swing Line Loan, require each Lender (including the Swing Line Lender) to make a Revolving Loan in the amount of such Lender's Pro Rata Share of such Swing Line Loan (including, without limitation, any interest accrued and unpaid thereon), for the purpose of repaying such Swing Line Loan. Not later than noon (Tulsa time) on the date of any notice received pursuant to this Section 2.20.4, each Lender shall make available its required Revolving Loan, in funds immediately available in Tulsa to the Agent at its address specified pursuant to Article XIII. Revolving Loans made pursuant to this Section 2.20.4 shall initially be Floating Rate Loans and thereafter may be continued as Floating Rate Loans or converted into Eurodollar Loans in the manner provided in Section 2.10 and subject to the other conditions and limitations set forth in this Article II. Unless a Lender shall have notified the Swing Line Lender, prior to its making any Swing Line Loan, that any applicable condition precedent set forth in Sections 4.1 or 4.2 had not then been satisfied, such 32

Lender's obligation to make Revolving Loans pursuant to this Section 2.20.4 to repay Swing Line Loans shall be unconditional, continuing, irrevocable and absolute and shall not be affected by any circumstances, including, without limitation, (a) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against the Agent, the Swing Line Lender or any other Person, (b) the occurrence or continuance of a Default or Unmatured Default, (c) any adverse change in the condition (financial or otherwise) of the Borrower, or (d) any other circumstances, happening or event whatsoever. In the event that any Lender fails to make payment to the Agent of any amount due under this Section 2.20.4, the Agent shall be entitled to receive, retain and apply against such obligation the principal and interest otherwise payable to such Lender hereunder until the Agent receives such payment from such Lender or such obligation is otherwise fully satisfied. In addition to the foregoing, if for any reason any Lender fails to make payment to the Agent of any amount due under this Section 2.20.4, such Lender shall be deemed, at the option of the Agent, to have unconditionally and irrevocably purchased from the Swing Line Lender, without recourse or warranty, an undivided interest and participation in the applicable Swing Line Loan in the amount of such Revolving Loan, and such interest and participation may be recovered from such Lender together with interest thereon at the Federal Funds Effective Rate for each day during the period commencing on the date of demand and ending on the date such amount is received. On the Facility Termination Date, the Borrower shall repay in full the outstanding principal balance of the Swing Line Loans. 2.21. Extension of Facility Termination Date. The Borrower may request an extension of the Facility Termination Date by submitting a request for an extension to the Agent (an "Extension Request") no more than 90 and no less than 30 days prior to the second (2nd) anniversary of the closing of this Agreement. Promptly upon receipt of an Extension Request, the Agent shall notify each Lender thereof and shall request each Lender to approve the Extension Request. Each Lender approving the Extension Request shall deliver its written consent no later than 15 days prior to such second (2nd) anniversary of the closing of this Agreement. If the consent of each of the Lenders is received by the Agent, the Facility Termination Date shall be extended by one year and the Agent shall promptly notify the Borrower and each Lender of the new Facility Termination Date. 2.22. Replacement of Lender. If the Borrower is required pursuant to Section 3.1, 3.2 or 3.5 to make any additional payment to any Lender or if any Lender's obligation to make or continue, or to convert Floating Rate Advances into, Eurodollar Advances shall be suspended pursuant to Section 3.3 (any Lender so affected an "Affected Lender"), the Borrower may elect, if such amounts continue to be charged or such suspension is still effective, to replace such Affected Lender as a Lender party to this Agreement, provided that no Default or Unmatured Default shall have occurred and be continuing at the time of such replacement, and provided further that, concurrently with such replacement, (i) another bank or other entity which is reasonably satisfactory to the Borrower and the Agent shall agree, as of such date, to purchase for cash the Advances and other Obligations due to the Affected Lender pursuant to an assignment substantially in the form of Exhibit C and to become a Lender for all purposes under this Agreement and to assume all obligations of the Affected Lender to be terminated as of such date and to comply with the requirements of Section 12.3 applicable to assignments, and (ii) the 33

Borrower shall pay to such Affected Lender in same day funds on the day of such replacement (A) all interest, fees and other amounts then accrued but unpaid to such Affected Lender by the Borrower hereunder to and including the date of termination, including without limitation payments due to such Affected Lender under Sections 3.1, 3.2 and 3.5, and (B) an amount, if any, equal to the payment which would have been due to such Lender on the day of such replacement under Section 3.4 had the Loans of such Affected Lender been prepaid on such date rather than sold to the replacement Lender. 2.23. Limitation of Interest. The Borrower, the Agent and the Lenders intend to strictly comply with all applicable laws, including applicable usury laws. Accordingly, the provisions of this Section 2.23 shall govern and control over every other provision of this Agreement or any other Loan Document which conflicts or is inconsistent with this Section 2.23, even if such provision declares that it controls. As used in this Section 2.23, 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 the Borrower or any other Person be obligated to pay, or any Lender have any right 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 Oklahoma or the applicable laws (if any) of the United States or of any other applicable state, 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 Highest Lawful Rate. On each day, if any, that the interest rate (the "Stated Rate") called for under this Agreement or any other Loan Document exceeds the Highest Lawful Rate, the rate at which interest shall accrue shall automatically be fixed by operation of this sentence at the Highest Lawful Rate for that day, and shall remain fixed at the Highest Lawful Rate for each day thereafter until the total amount of interest accrued equals the total amount of interest which would have accrued if there were no such ceiling rate as is imposed by this sentence. Thereafter, interest shall accrue at the Stated Rate unless and until the Stated Rate again exceeds the Highest Lawful Rate when the provisions of the immediately preceding sentence shall again automatically operate to limit the interest accrual rate. The daily interest rates to be used in calculating interest at the Highest Lawful Rate shall be determined by dividing the applicable Highest Lawful 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 which directly or indirectly relate to interest shall ever be construed without reference to this Section 2.21, 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 Highest Lawful 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 Highest Lawful 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 34

to such Lender, it shall be credited pro tanto against the then-outstanding principal balance of the 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. ARTICLE III YIELD PROTECTION; TAXES 3.1. Yield Protection. If, on or after the date of this Agreement, the adoption of any law or any governmental or quasi-governmental rule, regulation, policy, guideline or directive (whether or not having the force of law), or any change in the interpretation or administration thereof by any governmental or quasi-governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender or applicable Lending Installation or the LC Issuer with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency: (i) subjects any Lender or any applicable Lending Installation or the LC Issuer to any Taxes, or changes the basis of taxation of payments (other than with respect to Excluded Taxes) to any Lender or the LC Issuer in respect of its Eurodollar Loans, Facility LCs or participations therein, or (ii) imposes or increases or deems applicable any reserve, assessment, insurance charge, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender or any applicable Lending Installation or the LC Issuer (other than reserves and assessments taken into account in determining the interest rate applicable to Eurodollar Advances), or (iii) imposes any other condition the result of which is to increase the cost to any Lender or any applicable Lending Installation or the LC Issuer of making, funding or maintaining its Eurodollar Loans, or of issuing or participating in Facility LCs, reduces any amount receivable by any Lender or any applicable Lending Installation or the LC Issuer in connection with its Eurodollar Loans, Facility LCs or participations therein, or requires any Lender or any applicable Lending Installation or the LC Issuer to make any payment calculated by reference to the amount of Eurodollar Loans, Facility LCs or participations therein held or interest or LC Fees received by it, by an amount deemed material by such Lender or the LC Issuer as the case may be, and the result of any of the foregoing is to increase the cost to such Lender or applicable Lending Installation or the LC Issuer, as the case may be, of making or maintaining its Eurodollar Loans or Commitment or of issuing or participating in Facility LCs or to reduce the return received by such Lender or applicable Lending Installation or the LC Issuer, as the case may be, in connection with such Eurodollar Loans, Commitment, Facility LCs or participations therein, then, within 15 days of demand by such Lender or the LC Issuer, as the case may be, the 35

Borrower shall pay such Lender or the LC Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or the LC Issuer, as the case may be, for such increased cost or reduction in amount received. 3.2. Changes in Capital Adequacy Regulations. If a Lender or the LC Issuer determines the amount of capital required or expected to be maintained by such Lender or the LC Issuer, any Lending Installation of such Lender or the LC Issuer, or any corporation controlling such Lender or the LC Issuer is increased as a result of a Change, then, within 15 days of demand by such Lender or LC Issuer, the Borrower shall pay such Lender or the LC Issuer the amount necessary to compensate for any shortfall in the rate of return on the portion of such increased capital which such Lender or the LC Issuer determines is attributable to this Agreement, its Outstanding Credit Exposure or its Commitment to make Loans and issue or participate in Facility LCs, as the case may be, hereunder (after taking into account such Lender's or the LC Issuer's policies as to capital adequacy). "Change" means (i) any change after the date of this Agreement in the Risk-Based Capital Guidelines or (ii) any adoption of or change in any other law, governmental or quasi-governmental rule, regulation, policy, guideline, interpretation, or directive (whether or not having the force of law) after the date of this Agreement which affects the amount of capital required or expected to be maintained by any Lender or the LC Issuer or any Lending Installation or any corporation controlling any Lender or the LC Issuer. "Risk-Based Capital Guidelines" means (i) the risk-based capital guidelines in effect in the United States on the date of this Agreement, including transition rules, and (ii) the corresponding capital regulations promulgated by regulatory authorities outside the United States implementing the July 1988 report of the Basle Committee on Banking Regulation and Supervisory Practices Entitled "International Convergence of Capital Measurements and Capital Standards," including transition rules, and any amendments to such regulations adopted prior to the date of this Agreement. 3.3. Availability of Types of Advances. If any Lender determines that maintenance of its Eurodollar Loans at a suitable Lending Installation would violate any applicable law, rule, regulation, or directive, whether or not having the force of law, or if the Required Lenders determine that (i) deposits of a type and maturity appropriate to match fund Eurodollar Advances are not available or (ii) the interest rate applicable to Eurodollar Advances does not accurately reflect the cost of making or maintaining Eurodollar Advances, then the Agent shall suspend the availability of Eurodollar Advances and require any affected Eurodollar Advances to be repaid or converted to Floating Rate Advances, subject to the payment of any funding indemnification amounts required by Section 3.4. 3.4. Funding Indemnification. If any payment of a Eurodollar Advance occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, or a Eurodollar Advance is not made on the date specified by the Borrower for any reason other than default by the Lenders, the Borrower will indemnify each Lender for any loss or cost incurred by it resulting therefrom, including, without limitation, any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Advance. 36

3.5. Taxes. (i) All payments by the Borrower to or for the account of any Lender, the LC Issuer or the Agent hereunder or under any Note or Facility LC Application shall be made free and clear of and without deduction for any and all Taxes. If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to any Lender, the LC Issuer or the Agent, (a) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 3.5) such Lender, the LC Issuer or the Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (b) the Borrower shall make such deductions, (c) the Borrower shall pay the full amount deducted to the relevant authority in accordance with applicable law and (d) the Borrower shall furnish to the Agent the original copy of a receipt evidencing payment thereof within 30 days after such payment is made. (ii) In addition, the Borrower hereby agrees to pay any present or future stamp or documentary taxes and any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under any Note or Facility LC Application or from the execution or delivery of, or otherwise with respect to, this Agreement or any Note or Facility LC Application ("Other Taxes"). (iii) The Borrower hereby agrees to indemnify the Agent, the LC Issuer and each Lender for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed on amounts payable under this Section 3.5) paid by the Agent, the LC Issuer or such Lender as a result of its Commitment, any Loans made by it hereunder, or otherwise in connection with its participation in this Agreement and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. Payments due under this indemnification shall be made within 30 days of the date the Agent, the LC Issuer or such Lender makes demand therefor pursuant to Section 3.6. (iv) Each Lender that is not incorporated under the laws of the United States of America or a state thereof (each a "Non-U.S. Lender") agrees that it will, not more than ten Business Days after the date of this Agreement, (i) deliver to the Agent two duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI, certifying in either case that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, and (ii) deliver to the Agent a United States Internal Revenue Form W-8 or W-9, as the case may be, and certify that it is entitled to an exemption from United States backup withholding tax. Each Non-U.S. Lender further undertakes to deliver to each of the Borrower and the Agent (x) renewals or additional copies of such form (or any successor form) on or before the date that such form expires or becomes obsolete, and (y) after the occurrence of any event requiring a change in the most recent forms so delivered by it, such additional forms or amendments thereto as may be reasonably requested by the Borrower or the Agent. All forms or amendments described in the preceding sentence shall certify that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, unless an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form or amendment with respect to it and 37

such Lender advises the Borrower and the Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax. (v) For any period during which a Non-U.S. Lender has failed to provide the Borrower with an appropriate form pursuant to clause (iv), above (unless such failure is due to a change in treaty, law or regulation, or any change in the interpretation or administration thereof by any governmental authority, occurring subsequent to the date on which a form originally was required to be provided), such Non-U.S. Lender shall not be entitled to indemnification under this Section 3.5 with respect to Taxes imposed by the United States; provided that, should a Non-U.S. Lender which is otherwise exempt from or subject to a reduced rate of withholding tax become subject to Taxes because of its failure to deliver a form required under clause (iv), above, the Borrower shall take such steps as such Non-U.S. Lender shall reasonably request to assist such Non-U.S. Lender to recover such Taxes. (vi) Any Lender that is entitled to an exemption from or reduction of withholding tax with respect to payments under this Agreement or any Note pursuant to the law of any relevant jurisdiction or any treaty shall deliver to the Borrower (with a copy to the Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate. (vii) If the U.S. Internal Revenue Service or any other governmental authority of the United States or any other country or any political subdivision thereof asserts a claim that the Agent did not properly withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered or properly completed, because such Lender failed to notify the Agent of a change in circumstances which rendered its exemption from withholding ineffective, or for any other reason), such Lender shall indemnify the Agent fully for all amounts paid, directly or indirectly, by the Agent as tax, withholding therefor, or otherwise, including penalties and interest, and including taxes imposed by any jurisdiction on amounts payable to the Agent under this subsection, together with all costs and expenses related thereto (including attorneys fees and time charges of attorneys for the Agent, which attorneys may be employees of the Agent). The obligations of the Lenders under this Section 3.5(vii) shall survive the payment of the Obligations and termination of this Agreement. 3.6. Lender Statements; Survival of Indemnity. To the extent reasonably possible, each Lender shall designate an alternate Lending Installation with respect to its Eurodollar Loans to reduce any liability of the Borrower to such Lender under Sections 3.1, 3.2 and 3.5 or to avoid the unavailability of Eurodollar Advances under Section 3.3, so long as such designation is not, in the judgment of such Lender, disadvantageous to such Lender. Each Lender shall deliver a written statement of such Lender to the Borrower (with a copy to the Agent) as to the amount due, if any, under Section 3.1, 3.2, 3.4 or 3.5. Such written statement shall set forth in reasonable detail the calculations upon which such Lender determined such amount and shall be final, conclusive and binding on the Borrower in the absence of manifest error. Determination of amounts payable under such Sections in connection with a Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar Loan through the purchase of a deposit of the type and maturity corresponding to the deposit used as a reference in determining the Eurodollar Rate 38

applicable to such Loan, whether in fact that is the case or not. Unless otherwise provided herein, the amount specified in the written statement of any Lender shall be payable on demand after receipt by the Borrower of such written statement. The obligations of the Borrower under Sections 3.1, 3.2, 3.4 and 3.5 shall survive payment of the Obligations and termination of this Agreement. ARTICLE IV CONDITIONS PRECEDENT 4.1.

Any Lender may require a duly completed compliance certificate in substantially the form of Exhibit B as a condition to making a Credit Extension. ARTICLE V REPRESENTATIONS AND WARRANTIES 41

The Borrower represents and warrants to the Lenders that: 5.1. Existence and Standing. Each of the Borrower and its Subsidiaries is an entity duly and properly incorporated or organized, as the case may be, validly existing and (to the extent such concept applies to such entity) in good standing under the laws of its jurisdiction of incorporation or organization as set forth on Schedule "7" hereto, and has all requisite authority to conduct its business in each jurisdiction in which its business is conducted; subject to the Subsidiaries described on Schedule "8" hereto, which Borrower presently intends to dissolve. 5.2. Authorization and Validity. The Borrower has the power and authority and legal right to execute and deliver the Loan Documents to which it is a party and to perform its obligations thereunder. The execution and delivery by the Borrower of the Loan Documents to which it is a party and the performance of its obligations thereunder have been duly authorized by proper corporate proceedings, and the Loan Documents to which the Borrower is a party constitute legal, valid and binding obligations of the Borrower enforceable against the Borrower in accordance with their terms, except as enforceability may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors' rights generally. 5.3. No Conflict; Government Consent. Neither the execution and delivery by the Borrower of the Loan Documents to which it is a party, nor the consummation of the transactions therein contemplated, nor compliance with the provisions thereof will violate (i) any law, rule, regulation, order, writ, judgment, injunction, decree or award binding on the Borrower or any of its Subsidiaries or (ii) the Borrower's or any Subsidiary's articles or certificate of incorporation, partnership agreement, certificate of partnership, articles or certificate of organization, by-laws, or operating or other management agreement, as the case may be, or (iii) the provisions of any indenture, instrument or agreement to which the Borrower or any of its Subsidiaries is a party or is subject, or by which it, or its Property, is bound, or conflict with or constitute a default thereunder, or result in, or require, the creation or imposition of any Lien in, of or on the Property of the Borrower or a Subsidiary pursuant to the terms of any such indenture, instrument or agreement. No order, consent, adjudication, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, or other action in respect of any governmental or public body or authority, or any subdivision thereof, which has not been obtained by the Borrower or any of its Subsidiaries, is required to be obtained by the Borrower or any of its Subsidiaries in connection with the execution and delivery of the Loan Documents, the borrowings under this Agreement, the payment and performance by the Borrower of the Obligations or the legality, validity, binding effect or enforceability of any of the Loan Documents. 5.4. Financial Statements. The November 30, 2002 consolidated financial statements of the Borrower and its Subsidiaries (but the June 30, 2002 audited financial statements as to Hake Group) heretofore delivered to the Lenders were prepared in accordance with generally accepted accounting principles in effect on the date such statements were prepared and fairly present the consolidated financial condition and operations of the Borrower and its Subsidiaries at such date and the consolidated results of their operations for the period then ended. 42

5.5. Material Adverse Change. Since November 30, 2002 there has been no change in the business, Property, condition (financial or otherwise), prospects or results of operations of the Hake Group which is not covered by the purchase price holdback or of the Borrower and its Subsidiaries which could reasonably be expected to have a Material Adverse Effect. 5.6. Taxes. The Borrower and its Subsidiaries have filed all United States federal tax returns and all other tax returns which are required to be filed and have paid all taxes due pursuant to said returns or pursuant to any assessment received by the Borrower or any of its Subsidiaries, except such taxes, if any, as are being contested in good faith and as to which adequate reserves have been provided in accordance with Agreement Accounting Principles and as to which no Lien exists. The United States income tax returns of the Borrower and its Subsidiaries have been audited by the Internal Revenue Service through the fiscal year ended May 31, 1998 as to the Borrower, and January 31, 1997 as to the Hake Group. No tax liens have been filed and no claims are being asserted with respect to any such taxes. The charges, accruals and reserves on the books of the Borrower and its Subsidiaries in respect of any taxes or other governmental charges are adequate. 5.7. Litigation and Contingent Obligations. Except as set forth on Schedule "9", there is no litigation, arbitration, governmental investigation, proceeding or inquiry pending or, to the knowledge of any of their officers, threatened against or affecting the Borrower or any of its Subsidiaries which could reasonably be expected to have a Material Adverse Effect or which seeks to prevent, enjoin or delay the making of any Credit Extensions. Other than any liability incident to any litigation, arbitration or proceeding which (i) could not reasonably be expected to have a Material Adverse Effect or (ii) is set forth on Schedule "9", the Borrower has no material contingent obligations not provided for or disclosed in the financial statements referred to in Section 5.4. 5.8. Subsidiaries. Schedule "10" contains an accurate list of all Subsidiaries of the Borrower as of the date of this Agreement, setting forth their respective jurisdictions of organization and the percentage of their respective capital stock or other ownership interests owned by the Borrower or other Subsidiaries. All of the issued and outstanding shares of capital stock or other ownership interests of such Subsidiaries have been (to the extent such concepts are relevant with respect to such ownership interests) duly authorized and issued and are fully paid and non-assessable. 5.9. ERISA. The Unfunded Liabilities of all Single Employer Plans do not in the aggregate exceed $500,000. Neither the Borrower nor any other member of the Controlled Group has incurred, or is reasonably expected to incur, any withdrawal liability to Multiemployer Plans in excess of $500,000 in the aggregate. Each Plan complies in all material respects with all applicable requirements of law and regulations, no Reportable Event has occurred with respect to any Plan, neither the Borrower nor any other member of the Controlled Group has withdrawn from any Plan or initiated steps to do so, and no steps have been taken to reorganize or terminate any Plan. 5.10. Accuracy of Information. No information, exhibit or report furnished by the Borrower or any of its Subsidiaries to the Agent or to any Lender in connection with the 43

negotiation of, or compliance with, the Loan Documents contained any material misstatement of fact or omitted to state a material fact or any fact necessary to make the statements contained therein not misleading. 5.11. Regulation U. Margin stock (as defined in Regulation U) constitutes less than 25% of the value of those assets of the Borrower and its Subsidiaries which are subject to any limitation on sale, pledge, or other restriction hereunder. 5.12. Material Agreements. Neither the Borrower nor any Subsidiary is a party to any agreement or instrument or subject to any charter or other corporate restriction which could reasonably be expected to have a Material Adverse Effect. Neither the Borrower nor any Subsidiary is in default in the performance, observance or fulfillment of any of the obligations, covenants or conditions contained in (i) any agreement to which it is a party, which default could reasonably be expected to have a Material Adverse Effect or (ii) any agreement or instrument evidencing or governing Indebtedness. 5.13. Compliance With Laws. The Borrower and its Subsidiaries have complied with all applicable statutes, rules, regulations, orders and restrictions of any domestic or foreign government or any instrumentality or agency thereof having jurisdiction over the conduct of their respective businesses or the ownership of their respective Property except for any failure to comply with any of the foregoing which could not reasonably be expected to have a Material Adverse Effect. 5.14. Ownership of Properties. Except as set forth on Schedule "2", on the date of this Agreement, the Borrower and its Subsidiaries will have good title, free of all Liens other than those permitted by Section 6.15, to all of the Property and assets reflected in the Borrower's most recent consolidated financial statements provided to the Agent as owned by the Borrower and its Subsidiaries. 5.15. Plan Assets; Prohibited Transactions. The Borrower is not an entity deemed to hold "plan assets" within the meaning of 29 C.F.R. ss. 2510.3-101 of an employee benefit plan (as defined in Section 3(3) of ERISA) which is subject to Title I of ERISA or any plan (within the meaning of Section 4975 of the Code), and neither the execution of this Agreement nor the making of Credit Extensions hereunder gives rise to a prohibited transaction within the meaning of Section 406 of ERISA or Section 4975 of the Code. 5.16. Environmental Matters. Except as discussed on Schedule "11" hereto, in the ordinary course of its business, the officers of the Borrower consider the effect of Environmental Laws on the business of the Borrower and its Subsidiaries, in the course of which they identify and evaluate potential risks and liabilities accruing to the Borrower due to Environmental Laws. On the basis of this consideration, the Borrower has concluded that Environmental Laws cannot reasonably be expected to have a Material Adverse Effect. Neither the Borrower nor any Subsidiary has received any notice to the effect that its operations are not in material compliance with any of the requirements of applicable Environmental Laws or are the subject of any federal or state investigation evaluating whether any remedial action is needed to respond to a release of 44

any toxic or hazardous waste or substance into the environment, which non-compliance or remedial action could reasonably be expected to have a Material Adverse Effect. 5.17. Investment Company Act. Neither the Borrower nor any Subsidiary is an "investment company" or a company "controlled" by an "investment company", within the meaning of the Investment Company Act of 1940, as amended. 5.18. Public Utility Holding Company Act. Neither the Borrower nor any Subsidiary is a "holding company" or a "subsidiary company" of a "holding company", or an "affiliate" of a "holding company" or of a "subsidiary company" of a "holding company", within the meaning of the Public Utility Holding Company Act of 1935, as amended. 5.19. Subordinated Indebtedness. The Obligations constitute senior indebtedness which is entitled to the benefits of the subordination provisions of all outstanding Subordinated Indebtedness. 5.20. Post-Retirement Benefits. The present value of the expected cost of post-retirement medical and insurance benefits payable by the Borrower and its Subsidiaries to its employees and former employees, as estimated by the Borrower in accordance with procedures and assumptions deemed reasonable by the Required Lenders, does not exceed $500,000. 5.21. Insurance. The certificate signed by the President or Chief Financial Officer of the Borrower, that attests to the existence and adequacy of, and summarizes, the property and casualty insurance program carried by the Borrower with respect to itself and its Subsidiaries and that has been furnished by the Borrower to the Agent and the Lenders, is complete and accurate. This summary includes the insurer's or insurers' name(s), policy number(s), expiration date(s), amount(s) of coverage, type(s) of coverage, exclusion(s), and deductibles. This summary also includes similar information, and describes any reserves, relating to any self-insurance program that is in effect. 5.22. Solvency. (i) Immediately after the consummation of the transactions to occur on the date hereof and immediately following the making of each Loan, if any, made on the date hereof and after giving effect to the application of the proceeds of such Loans, (a) the fair value of the assets of the Borrower and its Subsidiaries on a consolidated basis, at a fair valuation, will exceed the debts and liabilities, subordinated, contingent or otherwise, of the Borrower and its Subsidiaries on a consolidated basis; (b) the present fair saleable value of the Property of the Borrower and its Subsidiaries on a consolidated basis will be greater than the amount that will be required to pay the probable liability of the Borrower and its Subsidiaries on a consolidated basis on their debts and other liabilities, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured; (c) the Borrower and its Subsidiaries on a consolidated basis will be able to pay their debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured; and (d) the Borrower and its Subsidiaries on a consolidated basis will not have unreasonably small capital with which to conduct the businesses in which they are engaged as such businesses are now conducted and are proposed to be conducted after the date hereof. 45

Payment and Performance Bonds. Attached hereto as Schedule "12" are representative copies of payment and performance bonds utilized by the Borrower and Subsidiaries. No such bonds (or any application or related documents) currently, or in the future will, evidence any collateral or security of any kind or nature in favor of the surety. 5.24. Acquisition. All conditions precedent for the completion of the Hake Acquisition have been satisfied.

If any other Default occurs, the Required Lenders (or the Agent with the consent of the Required Lenders) may (a) terminate or suspend the obligations of the Lenders to make Loans hereunder and the obligation and power of the LC Issuer to issue Facility LCs, or declare the Obligations to be due and payable, or both, whereupon the Obligations shall become immediately due and payable, without presentment, demand, protest or notice of any kind, all of which the Borrower hereby expressly waives, and (b) upon notice to the Borrower and in addition to the continuing right to demand payment of all amounts payable under this Agreement, make demand on the Borrower to pay, and the Borrower will, forthwith upon such 56

demand and without any further notice or act, pay to the Agent the Collateral Shortfall Amount, which funds shall be deposited in the Facility LC Collateral Account. (ii) If at any time while any Default is continuing, the Agent determines that the Collateral Shortfall Amount at such time is greater than zero, the Agent may make demand on the Borrower to pay, and the Borrower will, forthwith upon such demand and without any further notice or act, pay to the Agent the Collateral Shortfall Amount, which funds shall be deposited in the Facility LC Collateral Account. (iii) The Agent may at any time or from time to time after funds are deposited in the Facility LC Collateral Account, apply such funds to the payment of the Obligations and any other amounts as shall from time to time have become due and payable by the Borrower to the Lenders or the LC Issuer under the Loan Documents. (iv) At any time while any Default is continuing, neither the Borrower nor any Person claiming on behalf of or through the Borrower shall have any right to withdraw any of the funds held in the Facility LC Collateral Account. After all of the Obligations have been indefeasibly paid in full and the Aggregate Commitment has been terminated, any funds remaining in the Facility LC Collateral Account shall be returned by the Agent to the Borrower or paid to whomever may be legally entitled thereto at such time. (v) If, within thirty 30 days after acceleration of the maturity of the Obligations or termination of the obligations of the Lenders to make Loans and the obligation and power of the LC Issuer to issue Facility LCs hereunder as a result of any Default (other than any Default as described in Section 7.5, 7.6 or 7.7 with respect to the Borrower) and before any judgment or decree for the payment of the Obligations due shall have been obtained or entered, the Required Lenders (in their sole discretion) shall so direct, the Agent shall, by notice to the Borrower, rescind and annul such acceleration and/or termination. 8.2.

No delay or omission of the Lenders, the LC Issuer or the Agent to exercise any right under the Loan Documents shall impair such right or be construed to be a waiver of any Default or an acquiescence therein, and the making of a Credit Extension notwithstanding the existence of a Default or the inability of the Borrower to satisfy the conditions precedent to such Credit Extension shall not constitute any waiver or acquiescence. Any single or partial exercise of any such right shall not preclude other or further exercise thereof or the exercise of any other right, and no waiver, amendment or other variation of the terms, conditions or provisions of the Loan Documents whatsoever shall be valid unless in writing signed by the Lenders required pursuant to Section 8.2, and then only to the extent in such writing specifically set forth.

(i) The Borrower shall reimburse the Agent and the Arranger for any costs, internal charges and out-of-pocket expenses (including attorneys' fees and time charges of attorneys for the Agent, which attorneys may be employees of the Agent) paid or incurred by the Agent or the Arranger in connection with the preparation, negotiation, execution, delivery, syndication, distribution (including, without limitation, via the internet), review, amendment, modification, and administration of the Loan Documents. The Borrower also agrees to reimburse the Agent, the Arranger, the LC Issuer and the Lenders for any costs, internal charges and out-of-pocket expenses (including attorneys' fees and time charges of attorneys for the Agent, the Arranger, the LC Issuer and the Lenders, which attorneys may be employees of the Agent, the Arranger, the LC Issuer or the Lenders) paid or incurred by the Agent, the Arranger, the LC Issuer or any Lender in connection with the collection and enforcement of the Loan Documents. Expenses being reimbursed by the Borrower under this Section include, without limitation, the cost and expense of obtaining an appraisal of each parcel of real property or interest in real property described in the relevant Collateral Documents, which appraisal shall be in conformity with the applicable requirements of any law or any governmental rule, regulation, policy, guideline or directive (whether or not having the force of law), or any interpretation thereof, including, without limitation, the provisions of Title XI of the Financial Institutions Reform, Recovery and Enforcement Act of 1989, as amended, reformed or otherwise modified from time to time, and any rules promulgated to implement such provisions and costs and expenses incurred in connection with the Reports described in the following sentence. The Borrower acknowledges that from time to time Bank One may prepare and may distribute to the Lenders (but shall have no obligation or duty to prepare or to distribute to the Lenders) certain audit reports (the "Reports") pertaining to the Borrower's assets for internal use by Bank One 59

from information furnished to it by or on behalf of the Borrower, after Bank One has exercised its rights of inspection pursuant to this Agreement. (ii) The Borrower hereby further agrees to indemnify the Agent, the Arranger, the LC Issuer and each Lender, its directors, officers and employees against all losses, claims, damages, penalties, judgments, liabilities and expenses (including, without limitation, all expenses of litigation or preparation therefor whether or not the Agent, the Arranger, the LC Issuer or any Lender is a party thereto) which any of them may pay or incur arising out of or relating to this Agreement, the other Loan Documents, the transactions contemplated hereby or the direct or indirect application or proposed application of the proceeds of any Credit Extension hereunder except to the extent that they are determined in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the party seeking indemnification. The obligations of the Borrower under this Section 9.6 shall survive the termination of this Agreement. 9.7. Numbers of Documents. All statements, notices, closing documents, and requests hereunder shall be furnished to the Agent with sufficient counterparts so that the Agent may furnish one to each of the Lenders. 9.8. Accounting. Except as provided to the contrary herein, all accounting terms used herein shall be interpreted and all accounting determinations hereunder shall be made in accordance with Agreement Accounting Principles, except that any calculation or determination which is to be made on a consolidated basis shall be made for the Borrower and all its Subsidiaries, including those Subsidiaries, if any, which are unconsolidated on the Borrower's audited financial statements. 9.9. Severability of Provisions. Any provision in any Loan Document that is held to be inoperative, unenforceable, or invalid in any jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable, or invalid without affecting the remaining provisions in that jurisdiction or the operation, enforceability, or validity of that provision in any other jurisdiction, and to this end the provisions of all Loan Documents are declared to be severable. 9.10. Nonliability of Lenders. The relationship between the Borrower on the one hand and the Lenders, the LC Issuer and the Agent on the other hand shall be solely that of borrower and lender. Neither the Agent, the Arranger, the LC Issuer nor any Lender shall have any fiduciary responsibilities to the Borrower. Neither the Agent, the Arranger, the LC Issuer nor any Lender undertakes any responsibility to the Borrower to review or inform the Borrower of any matter in connection with any phase of the Borrower's business or operations. The Borrower agrees that neither the Agent, the Arranger, the LC Issuer nor any Lender shall have liability to the Borrower (whether sounding in tort, contract or otherwise) for losses suffered by the Borrower in connection with, arising out of, or in any way related to, the transactions contemplated and the relationship established by the Loan Documents, or any act, omission or event occurring in connection therewith, unless it is determined in a final non-appealable judgment by a court of competent jurisdiction that such losses resulted from the gross negligence or willful misconduct of the party from which recovery is sought. Neither the Agent, the Arranger, the LC Issuer nor any Lender shall have any liability with respect to, and the Borrower 60

hereby waives, releases and agrees not to sue for, any special, indirect or consequential damages suffered by the Borrower in connection with, arising out of, or in any way related to the Loan Documents or the transactions contemplated thereby. 9.11.

ARTICLE X THE AGENT 10.1. Appointment; Nature of Relationship. Bank One, Oklahoma, NA is hereby appointed by each of the Lenders as its contractual representative (herein referred to as the "Agent") hereunder and under each other Loan Document, and each of the Lenders irrevocably authorizes the Agent to act as the contractual representative of such Lender with the rights and duties expressly set forth herein and in the other Loan Documents. The Agent agrees to act as such contractual representative upon the express conditions contained in this Article X. Notwithstanding the use of the defined term "Agent," it is expressly understood and agreed that the Agent shall not have any fiduciary responsibilities to any Lender by reason of this Agreement or any other Loan Document and that the Agent is merely acting as the contractual representative of the Lenders with only those duties as are expressly set forth in this Agreement and the other Loan Documents. In its capacity as the Lenders' contractual representative, the Agent (i) does not hereby assume any fiduciary duties to any of the Lenders, (ii) is a "representative" of the Lenders within the meaning of the term "secured party" as defined in the Oklahoma Uniform Commercial Code and (iii) is acting as an independent contractor, the rights and duties of which 61

are limited to those expressly set forth in this Agreement and the other Loan Documents. Each of the Lenders hereby agrees to assert no claim against the Agent on any agency theory or any other theory of liability for breach of fiduciary duty, all of which claims each Lender hereby waives. 10.2. Powers. The Agent shall have and may exercise such powers under the Loan Documents as are specifically delegated to the Agent by the terms of each thereof, together with such powers as are reasonably incidental thereto. The Agent shall have no implied duties to the Lenders, or any obligation to the Lenders to take any action thereunder except any action specifically provided by the Loan Documents to be taken by the Agent. 10.3. General Immunity. Neither the Agent nor any of its directors, officers, agents or employees shall be liable to the Borrower, the Lenders or any Lender for any action taken or omitted to be taken by it or them hereunder or under any other Loan Document or in connection herewith or therewith except to the extent such action or inaction is determined in a final non-appealable judgment by a court of competent jurisdiction to have arisen from the gross negligence or willful misconduct of such Person. 10.4. No Responsibility for Loans, Recitals, etc. Neither the Agent nor any of its directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into, or verify (a) any statement, warranty or representation made in connection with any Loan Document or any borrowing hereunder; (b) the performance or observance of any of the covenants or agreements of any obligor under any Loan Document, including, without limitation, any agreement by an obligor to furnish information directly to each Lender; (c) the satisfaction of any condition specified in Article IV, except receipt of items required to be delivered solely to the Agent; (d) the existence or possible existence of any Default or Unmatured Default; (e) the validity, enforceability, effectiveness, sufficiency or genuineness of any Loan Document or any other instrument or writing furnished in connection therewith; (f) the value, sufficiency, creation, perfection or priority of any Lien in any collateral security; or (g) the financial condition of the Borrower or any guarantor of any of the Obligations or of any of the Borrower's or any such guarantor's respective Subsidiaries. The Agent shall have no duty to disclose to the Lenders information that is not required to be furnished by the Borrower to the Agent at such time, but is voluntarily furnished by the Borrower to the Agent (either in its capacity as Agent or in its individual capacity). 10.5. Action on Instructions of Lenders. The Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and under any other Loan Document in accordance with written instructions signed by the Required Lenders (or, if required in this Agreement, the Lenders), and such instructions and any action taken or failure to act pursuant thereto shall be binding on all of the Lenders. The Lenders hereby acknowledge that the Agent shall be under no duty to take any discretionary action permitted to be taken by it pursuant to the provisions of this Agreement or any other Loan Document unless it shall be requested in writing to do so by the Required Lenders. The Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Loan Document unless it shall first be indemnified to its satisfaction by the Lenders pro rata against any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action. 62

10.6. Employment of Agents and Counsel. The Agent may execute any of its duties as Agent hereunder and under any other Loan Document by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Lenders, except as to money or securities received by it or its authorized agents, for the default or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. The Agent shall be entitled to advice of counsel concerning the contractual arrangement between the Agent and the Lenders and all matters pertaining to the Agent's duties hereunder and under any other Loan Document. 10.7. Reliance on Documents; Counsel. The Agent shall be entitled to rely upon any Note, notice, consent, certificate, affidavit, letter, telegram, statement, paper or document believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, and, in respect to legal matters, upon the opinion of counsel selected by the Agent, which counsel may be employees of the Agent. 10.8. Agent's Reimbursement and Indemnification. The Lenders agree to reimburse and indemnify the Agent ratably in proportion to their respective Commitments (or, if the Commitments have been terminated, in proportion to their Commitments immediately prior to such termination) (i) for any amounts not reimbursed by the Borrower for which the Agent is entitled to reimbursement by the Borrower under the Loan Documents, (ii) for any other expenses incurred by the Agent on behalf of the Lenders, in connection with the preparation, execution, delivery, administration and enforcement of the Loan Documents (including, without limitation, for any expenses incurred by the Agent in connection with any dispute between the Agent and any Lender or between two or more of the Lenders) and (iii) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Agent in any way relating to or arising out of the Loan Documents or any other document delivered in connection therewith or the transactions contemplated thereby (including, without limitation, for any such amounts incurred by or asserted against the Agent in connection with any dispute between the Agent and any Lender or between two or more of the Lenders), or the enforcement of any of the terms of the Loan Documents or of any such other documents, provided that (i) no Lender shall be liable for any of the foregoing to the extent any of the foregoing is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Agent and (ii) any indemnification required pursuant to Section 3.5(vii) shall, notwithstanding the provisions of this Section 10.8, be paid by the relevant Lender in accordance with the provisions thereof. The obligations of the Lenders under this Section 10.8 shall survive payment of the Obligations and termination of this Agreement. 10.9. Notice of Default. The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Unmatured Default hereunder unless the Agent has received written notice from a Lender or the Borrower referring to this Agreement describing such Default or Unmatured Default and stating that such notice is a "notice of default". In the event that the Agent receives such a notice, the Agent shall give prompt notice thereof to the Lenders. 63

10.10. Rights as a Lender. In the event the Agent is a Lender, the Agent shall have the same rights and powers hereunder and under any other Loan Document with respect to its Commitment and its Loans as any Lender and may exercise the same as though it were not the Agent, and the term "Lender" or "Lenders" shall, at any time when the Agent is a Lender, unless the context otherwise indicates, include the Agent in its individual capacity. The Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of trust, debt, equity or other transaction, in addition to those contemplated by this Agreement or any other Loan Document, with the Borrower or any of its Subsidiaries in which the Borrower or such Subsidiary is not restricted hereby from engaging with any other Person. The Agent, in its individual capacity, is not obligated to remain a Lender. 10.11. Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Agent, the Arranger or any other Lender and based on the financial statements prepared by the Borrower and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Loan Documents. Each Lender also acknowledges that it will, independently and without reliance upon the Agent, the Arranger 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. 10.12. Successor Agent. The Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower, such resignation to be effective upon the appointment of a successor Agent or, if no successor Agent has been appointed, forty-five days after the retiring Agent gives notice of its intention to resign. The Agent may be removed at any time with or without cause by written notice received by the Agent from the Required Lenders, such removal to be effective on the date specified by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right to appoint, on behalf of the Borrower and the Lenders, a successor Agent. If no successor Agent shall have been so appointed by the Required Lenders within thirty days after the resigning Agent's giving notice of its intention to resign, then the resigning Agent may appoint, on behalf of the Borrower and the Lenders, a successor Agent. Notwithstanding the previous sentence, the Agent may at any time without the consent of the Borrower or any Lender, appoint any of its Affiliates which is a commercial bank as a successor Agent hereunder. If the Agent has resigned or been removed and no successor Agent has been appointed, the Lenders may perform all the duties of the Agent hereunder and the Borrower shall make all payments in respect of the Obligations to the applicable Lender and for all other purposes shall deal directly with the Lenders. No successor Agent shall be deemed to be appointed hereunder until such successor Agent has accepted the appointment. Any such successor Agent shall be a commercial bank having capital and retained earnings of at least $100,000,000. 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 resigning or removed Agent. Upon the effectiveness of the resignation or removal of the Agent, the resigning or removed Agent shall be discharged from its duties and obligations hereunder and under the Loan Documents. After the effectiveness of the resignation or removal of an Agent, the provisions of this Article X shall continue in effect for the benefit of such Agent in respect of any actions taken or omitted to be taken by it while it was acting as the Agent hereunder and under the other Loan Documents. In 64

the event that there is a successor to the Agent by merger, or the Agent assigns its duties and obligations to an Affiliate pursuant to this Section 10.12, then the term "Prime Rate" as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Agent. 10.13. Agent and Arranger Fees. The Borrower agrees to pay to the Agent and the Arranger, for their respective accounts, the fees agreed to by the Borrower, the Agent and the Arranger pursuant to that certain letter agreement dated January 17, 2003, or as otherwise agreed from time to time. 10.14. Delegation to Affiliates. The Borrower and the Lenders agree that the Agent may delegate any of its duties under this Agreement to any of its Affiliates. Any such Affiliate (and such Affiliate's directors, officers, agents and employees) which performs duties in connection with this Agreement shall be entitled to the same benefits of the indemnification, waiver and other protective provisions to which the Agent is entitled under Articles IX and X. 10.15. Execution of Collateral Documents. The Lenders hereby empower and authorize the Agent to execute and deliver to the Borrower on their behalf the Security Agreement(s) and all related financing statements and any financing statements, agreements, documents or instruments as shall be necessary or appropriate to effect the purposes of the Security Agreement(s). 10.16. Collateral Releases. The Lenders hereby empower and authorize the Agent to execute and deliver to the Borrower on their behalf any agreements, documents or instruments as shall be necessary or appropriate to effect any releases of Collateral which shall be permitted by the terms hereof or of any other Loan Document or which shall otherwise have been approved by the Required Lenders (or, if required by the terms of Section 8.2, all of the Lenders) in writing. ARTICLE XI SETOFF; RATABLE PAYMENTS 11.1. Setoff. In addition to, and without limitation of, any rights of the Lenders under applicable law, if the Borrower becomes insolvent, however evidenced, or any Default occurs, any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other Indebtedness at any time held or owing by any Lender or any Affiliate of any Lender to or for the credit or account of the Borrower may be offset and applied toward the payment of the Obligations owing to such Lender, whether or not the Obligations, or any part hereof, shall then be due. 11.2. Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to it upon its Outstanding Credit Exposure (other than payments received pursuant to Section 3.1, 3.2, 3.4 or 3.5) in a greater proportion than that received by any other Lender, such Lender agrees, promptly upon demand, to purchase a portion of the Aggregate Outstanding Credit Exposure held by the other Lenders so that after such purchase each Lender will hold its Pro Rata Share of the Aggregate Outstanding Credit Exposure. If any Lender, whether in 65

connection with setoff or amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Lender agrees, promptly upon demand, to take such action necessary such that all Lenders share in the benefits of such collateral ratably in proportion to their respective Pro Rata Shares of the Aggregate Outstanding Credit Exposure. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made. ARTICLE XII BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS 12.1. Successors and Assigns. The terms and provisions of the Loan Documents shall be binding upon and inure to the benefit of the Borrower and the Lenders and their respective successors and assigns permitted hereby, except that (i) the Borrower shall not have the right to assign its rights or obligations under the Loan Documents without the prior written consent of each Lender, (ii) any assignment by any Lender must be made in compliance with Section 12.3, and (iii) any transfer by Participation must be made in compliance with Section 12.2. Any attempted assignment or transfer by any party not made in compliance with this Section 12.1 shall be null and void, unless such attempted assignment or transfer is treated as a participation in accordance with Section 12.3.2. The parties to this Agreement acknowledge that clause (ii) of this Section 12.1 relates only to absolute assignments and this Section 12.1 does not prohibit assignments creating security interests, including, without limitation, (x) any pledge or assignment by any Lender of all or any portion of its rights under this Agreement and any Note to a Federal Reserve Bank or (y) in the case of a Lender which is a Fund, any pledge or assignment of all or any portion of its rights under this Agreement and any Note to its trustee in support of its obligations to its trustee; provided, however, that no such pledge or assignment creating a security interest shall release the transferor Lender from its obligations hereunder unless and until the parties thereto have complied with the provisions of Section 12.3. The Agent may treat the Person which made any Loan or which holds any Note as the owner thereof for all purposes hereof unless and until such Person complies with Section 12.3; provided, however, that the Agent may in its discretion (but shall not be required to) follow instructions from the Person which made any Loan or which holds any Note to direct payments relating to such Loan or Note to another Person. Any assignee of the rights to any Loan or any Note agrees by acceptance of such assignment to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the owner of the rights to any Loan (whether or not a Note has been issued in evidence thereof), shall be conclusive and binding on any subsequent holder or assignee of the rights to such Loan. 12.2. Participations. 12.2.1. Permitted Participants; Effect. Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time sell to one or more banks or other entities ("Participants") participating interests in any Outstanding Credit Exposure of such Lender, any Note held by such Lender, any Commitment of such 66

Lender or any other interest of such Lender under the Loan Documents. In the event of any such sale by a Lender of participating interests to a Participant, such Lender's obligations under the Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, such Lender shall remain the owner of its Outstanding Credit Exposure and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents, all amounts payable by the Borrower under this Agreement shall be determined as if such Lender had not sold such participating interests, and the Borrower and the Agent shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under the Loan Documents. 12.2.2. Voting Rights. Each Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents other than any amendment, modification or waiver with respect to any Credit Extension or Commitment in which such Participant has an interest which would require consent of all of the Lenders pursuant to the terms of Section 8.2 or of any other Loan Document. 12.2.3. Benefit of Certain Provisions. The Borrower agrees that each Participant shall be deemed to have the right of setoff provided in Section 11.1 in respect of its participating interest in amounts owing under the Loan Documents to the same extent as if the amount of its participating interest were owing directly to it as a Lender under the Loan Documents, provided that each Lender shall retain the right of setoff provided in Section 11.1 with respect to the amount of participating interests sold to each Participant. The Lenders agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 11.1, agrees to share with each Lender, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 11.2 as if each Participant were a Lender. The Borrower further agrees that each Participant shall be entitled to the benefits of Sections 3.1, 3.2, 3.4 and 3.5 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.3, provided that (i) a Participant shall not be entitled to receive any greater payment under Section 3.1, 3.2 or 3.5 than the Lender who sold the participating interest to such Participant would have received had it retained such interest for its own account, unless the sale of such interest to such Participant is made with the prior written consent of the Borrower, and (ii) any Participant not incorporated under the laws of the United States of America or any State thereof agrees to comply with the provisions of Section 3.5 to the same extent as if it were a Lender. 12.3. Assignments. 12.3.1. Permitted Assignments. Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time assign to one or more banks or other entities ("Purchasers") all or any part of its rights and obligations under the Loan Documents. Such assignment shall be substantially in the form of Exhibit C or in such other form as may be agreed to by the parties thereto. The consent of the Borrower, the Agent and the LC Issuer shall be required prior to an assignment becoming effective with 67

respect to a Purchaser which is not a Lender or an Affiliate thereof; provided, however, that if a Default has occurred and is continuing, the consent of the Borrower shall not be required. Such consent shall not be unreasonably withheld or delayed. Each such assignment with respect to a Purchaser which is not a Lender or an Affiliate thereof shall (unless each of the Borrower and the Agent otherwise consents) be in an amount not less than the lesser of (i) $5,000,000 or (ii) the remaining amount of the assigning Lender's Commitment (calculated as at the date of such assignment) or outstanding Loans (if the applicable Commitment has been terminated). 12.3.2. Effect; Effective Date. Upon (i) delivery to the Agent of a notice of assignment, substantially in the form attached as Exhibit I to Exhibit C (a "Notice of Assignment"), together with any consents required by Section 12.3.1, and (ii) payment of a $3,500 fee to the Agent for processing such assignment, such assignment shall become effective on the effective date specified in such Notice of Assignment. The Notice of Assignment shall contain a representation by the Purchaser to the effect that none of the consideration used to make the purchase of the Commitment and Outstanding Credit Exposure under the applicable assignment agreement are "plan assets" as defined under ERISA and that the rights and interests of the Purchaser in and under the Loan Documents will not be "plan assets" under ERISA. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Lender party to this Agreement and any other Loan Document executed by or on behalf of the Lenders and shall have all the rights and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party hereto, and no further consent or action by the Borrower, the Lenders or the Agent shall be required to release the transferor Lender with respect to the percentage of the Aggregate Commitment and Outstanding Credit Exposure assigned to such Purchaser. Upon the consummation of any assignment to a Purchaser pursuant to this Section 12.3.2, the transferor Lender, the Agent and the Borrower shall, if the transferor Lender or the Purchaser desires that its Loans be evidenced by Notes, make appropriate arrangements so that new Notes or, as appropriate, replacement Notes are issued to such transferor Lender and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their respective Commitments, as adjusted pursuant to such assignment. 12.3.3. Register. The Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in Tulsa, Oklahoma a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the "Register"). The entries in the Register shall be conclusive, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice. 68

12.4. Dissemination of Information. The Borrower authorizes each Lender to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a "Transferee") and any prospective Transferee any and all information in such Lender's possession concerning the creditworthiness of the Borrower and its Subsidiaries, including without limitation any information contained in any Reports; provided that each Transferee and prospective Transferee agrees to be bound by Section 9.11 of this Agreement. 12.5. Tax Treatment. If any interest in any Loan Document is transferred to any Transferee which is not incorporated under the laws of the United States or any State thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 3.5(iv). ARTICLE XIII NOTICES 13.1. Notices. Except as otherwise permitted by Section 2.14 with respect to borrowing notices, all notices, requests and other communications to any party hereunder shall be in writing (including electronic transmission, facsimile transmission or similar writing) and shall be given to such party: (x) in the case of the Borrower or the Agent, at its address or facsimile number set forth on the signature pages hereof, (y) in the case of any Lender, at its address or facsimile number set forth below its signature hereto or in its administrative questionnaire, or (z) in the case of any party, at such other address or facsimile number as such party may hereafter specify for the purpose by notice to the Agent and the Borrower in accordance with the provisions of this Section 13.1. Each such notice, request or other communication shall be effective (i) if given by facsimile transmission, when transmitted to the facsimile number specified in this Section and confirmation of receipt is received, (ii) if given by mail, 72 hours after such communication is deposited in the mails with first class postage prepaid, addressed as aforesaid, or (iii) if given by any other means, when delivered (or, in the case of electronic transmission, received) at the address specified in this Section; provided that notices to the Agent under Article II shall not be effective until received. 13.2. Change of Address. The Borrower, the Agent and any Lender may each change the address for service of notice upon it by a notice in writing to the other parties hereto. ARTICLE XIV COUNTERPARTS This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one agreement, and any of the parties hereto may execute this 69

Agreement by signing any such counterpart. This Agreement shall be effective when it has been executed by the Borrower, the Agent, the LC Issuer and the Lenders and each party has notified the Agent by facsimile transmission or telephone that it has taken such action. ARTICLE XV CHOICE OF LAW; CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL 15.1. CHOICE OF LAW. THE LOAN DOCUMENTS (OTHER THAN THOSE CONTAINING A CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF OKLAHOMA, BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS. 15.2. CONSENT TO JURISDICTION.

EXHIBIT A FORM OF OPINION The Agent, the LC Issuer and the Lenders who are parties to the Credit Agreement described below. Gentlemen/Ladies: We are counsel for (the "Borrower"), and have represented the ------------ Borrower in connection with its execution and delivery of a Credit Agreement dated as of March , 2003 (the "Agreement") among the Borrower, the Lenders --- named therein, and Bank One, Oklahoma, NA, as Agent and as LC Issuer, and providing for Credit Extensions in an aggregate principal amount not exceeding $32,500,000 at any one time outstanding. All capitalized terms used in this opinion and not otherwise defined herein shall have the meanings attributed to them in the Agreement. We have examined the Borrower's **[describe constitutive documents of Borrower and appropriate evidence of authority to enter into the transaction]**, the Loan Documents and such other matters of fact and law which we deem necessary in order to render this opinion. Based upon the foregoing, it is our opinion that: l.Each of the Borrower and its Subsidiaries is a corporation, partnership or limited liability company duly and properly incorporated or organized, as the case may be, validly existing and (to the extent such concept applies to such entity) in good standing under the laws of its jurisdiction of incorporation or organization and has all requisite authority to conduct its business in each jurisdiction in which its business is conducted. 2.The execution and delivery by the Borrower of the Loan Documents **[to which it is a party]** and the performance by the Borrower of its obligations thereunder have been duly authorized by proper corporate proceedings on the part of the Borrower and will not: (a) require any consent of the Borrower's shareholders or members (other than any such consent as has already been given and remains in full force and effect); (b) violate (i) any law, rule, regulation, order, writ, judgment, injunction, decree or award binding on the Borrower or any of its Subsidiaries or (ii) the Borrower's or any Subsidiary's articles or certificate of incorporation, partnership agreement, certificate of partnership, articles or certificate of organization, by-laws, or operating or other management agreement, as the case may be, or (iii) the provisions of any indenture, instrument or agreement to which the Borrower or any of its Subsidiaries is a party or is 78

subject, or by which it, or its Property,is bound, or conflict with or constitute a default thereunder; or (c) result in, or require, the creation or imposition of any Lien in, of or on the Property of the Borrower or a Subsidiary pursuant to the terms of any indenture, instrument or agreement binding upon the Borrower or any of its Subsidiaries. 3.The Loan Documents **[to which the Borrower is a party]** have been duly executed and delivered by the Borrower and constitute legal, valid and binding obligations of the Borrower enforceable against the Borrower in accordance with their terms except to the extent the enforcement thereof may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors' rights generally and subject also to the availability of equitable remedies if equitable remedies are sought. **[NOTE: If there are Loan Documents executed by related entities other than the Borrower, separate provisions of the opinion or additional opinions should cover those documents and their enforceability against such parties.]** 4.There is no litigation, arbitration, governmental investigation, proceeding or inquiry pending or, to the best of our knowledge after due inquiry, threatened against the Borrower or any of its Subsidiaries which, if adversely determined, could reasonably be expected to have a Material Adverse Effect. 5.No order, consent, adjudication, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, or other action in respect of any governmental or public body or authority, or any subdivision thereof, which has not been obtained by the Borrower or any of its Subsidiaries, is required to be obtained by the Borrower or any of its Subsidiaries in connection with the execution and delivery of the Loan Documents, the borrowings under the Agreement, the payment and performance by the Borrower of the Obligations, or the legality, validity, binding effect or enforceability of any of the Loan Documents. **[6. The Obligations constitute senior indebtedness which is entitled to the benefits of the subordination provisions of all outstanding Subordinated Indebtedness.]** **[7.The provisions of the Collateral Documents are sufficient to create in favor of the Lenders and, to the extent they have entered into Rate Management Transactions with the Borrower, the Lenders' Affiliates, a security interest in all right, title and interest of the Borrower in those items and types of collateral described in the Collateral Documents in which a security interest may be created under Article 9 of the Uniform Commercial Code as in effect on the date hereof in Oklahoma. Financing statements on Form UCC-1's have been duly executed by the Borrower and have been duly filed in each filing office indicated in Exhibit A hereto under the Uniform Commercial Code in effect in each state in which said filing offices are located. The description of the collateral set forth in said financing statements is sufficient to perfect a security interest in the items and types of collateral described therein in which a security interest may be perfected by the filing of a financing statement under the Uniform Commercial Code as in effect in such states. Such filings are sufficient to perfect the security interest created by the Collateral Documents in all right, title and interest of the Borrower in those items and types of 79

collateral described in the Collateral Documents in which a security interest may be perfected by the filing of a financing statement under the Uniform Commercial Code in such states, except that we express no opinion as to personal property affixed to real property in such manner as to become a fixture under the laws of any state in which the collateral may be located and we call your attention to the fact that the Lenders' (and, if applicable, their Affiliates') security interest in certain of such collateral may not be perfected by filing financing statements under the Uniform Commercial Code.]** This opinion may be relied upon by the Agent, the LC Issuer, the Lenders and their participants, assignees and other transferees. Very truly yours, 80

Each of the Subsidiary Guarantors represents and warrants (which representations and warranties shall be deemed to have been renewed upon each Borrowing Date under the Credit Agreement) that: (a) It is a corporation, partnership or limited liability company duly and properly incorporated or organized, as the case may be, validly existing and (to the extent such concept applies to such entity) in good standing under the laws of its jurisdiction of incorporation or organization and has all requisite authority to conduct its business in each jurisdiction in which its business is conducted. (b) It has the power and authority and legal right to execute and deliver this Guaranty and to perform its obligations hereunder. The execution and delivery by it of this Guaranty and the performance of its obligations hereunder have been duly authorized by proper corporate proceedings, and this Guaranty constitutes a legal, valid and binding obligation of such Subsidiary Guarantor enforceable against it in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors' rights generally. (c) Neither the execution and delivery by it of this Guaranty, nor the consummation of the transactions herein contemplated, nor compliance with the provisions hereof will violate (i) any law, rule, regulation, order, writ, judgment, injunction, decree or award 101

binding on it or any of its subsidiaries or (ii) its articles or certificate of incorporation, partnership agreement, certificate of partnership, articles or certificate of organization, by-laws, or operating or other management agreement, as the case may be, or (iii) the provisions of any indenture, instrument or agreement to which it or any of its subsidiaries is a party or is subject, or by which it, or its Property, is bound, or conflict with or constitute a default thereunder, or result in, or require, the creation or imposition of any Lien in, of or on the Property of such Subsidiary Guarantor or a subsidiary thereof pursuant to the terms of any such indenture, instrument or agreement.

SECTION 2.2. Covenants.

SECTION 3. The Guaranty. Subject to Section 9 hereof, each of the Subsidiary Guarantors hereby absolutely and unconditionally guarantees, as primary obligor and not as surety, the full and punctual payment (whether at stated maturity, upon acceleration or early termination or otherwise, and at all times thereafter) and performance of the Obligations and the Rate Management Obligations, including without limitation any such Obligations or Rate Management Obligations incurred or accrued during the pendency of any bankruptcy, insolvency, receivership or other similar proceeding, whether or not allowed or allowable in such proceeding (collectively, subject to the provisions of Section 9 hereof, being referred to collectively as the "Guaranteed Obligations"). Upon failure by the Principal to pay punctually any such amount, each of the Subsidiary Guarantors agrees that it shall forthwith on demand pay to the Agent for the benefit of the Lenders and, if applicable, their Affiliates, the amount not so paid at the place and in the manner specified in the Credit Agreement, any Note, any Rate Management Transaction or the relevant Loan Document, as the case may be. This Guaranty is a guaranty of payment and not of collection.

SECTION 5. Discharge Only Upon Payment In Full: Reinstatement In Certain Circumstances. Each of the Subsidiary Guarantor's obligations hereunder shall remain in full force and effect until all Guaranteed Obligations shall have been indefeasibly paid in full, the Commitments under the Credit Agreement shall have terminated or expired and all Rate Management Transactions have terminated or expired. If at any time any payment of the principal of or interest on any Note or any other amount payable by the Principal or any other party under the Credit Agreement, any Rate Management Transaction or any other Loan Document is rescinded or 103

must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Principal or otherwise, each of the Subsidiary Guarantor's obligations hereunder with respect to such payment shall be reinstated as though such payment had been due but not made at such time. SECTION 6. Waivers. Each of the Subsidiary Guarantors irrevocably waives acceptance hereof, presentment, demand, protest and, to the fullest extent permitted by law, any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person against the Principal, any other guarantor of any of the Guaranteed Obligations, or any other Person. SECTION 7. Subrogation. Each of the Subsidiary Guarantors hereby agrees not to assert any right, claim or cause of action, including, without limitation, a claim for subrogation, reimbursement, indemnification or otherwise, against the Principal arising out of or by reason of this Guaranty or the obligations hereunder, including, without limitation, the payment or securing or purchasing of any of the Guaranteed Obligations by any of the Subsidiary Guarantors unless and until the Guaranteed Obligations are indefeasibly paid in full, any commitment to lend under the Credit Agreement and any other Loan Documents is terminated and all Rate Management Transactions have terminated or expired. SECTION 8. Stay of Acceleration. If acceleration of the time for payment of any of the Guaranteed Obligations is stayed upon the insolvency, bankruptcy or reorganization of the Principal, all such amounts otherwise subject to acceleration under the terms of the Credit Agreement, any Note, any Rate Management Transaction or any other Loan Document shall nonetheless be payable by each of the Subsidiary Guarantors hereunder forthwith on demand by the Agent made at the request of the Required Lenders. SECTION 9. Limitation on Obligations. (a) The provisions of this Guaranty are severable, and in any action or proceeding involving any state corporate law, or any state, federal or foreign bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of any Subsidiary Guarantor under this Guaranty would otherwise be held or determined to be avoidable, invalid or unenforceable on account of the amount of such Subsidiary Guarantor's liability under this Guaranty, then, notwithstanding any other provision of this Guaranty to the contrary, the amount of such liability shall, without any further action by the Subsidiary Guarantors, the Agent or any Lender, be automatically limited and reduced to the highest amount that is valid and enforceable as determined in such action or proceeding (such highest amount determined hereunder being the relevant Subsidiary Guarantor's "Maximum Liability"). This Section 9(a) with respect to the Maximum Liability of the Subsidiary Guarantors is intended solely to preserve the rights of the Agent hereunder to the maximum extent not subject to avoidance under applicable law, and neither the Subsidiary Guarantor nor any other person or entity shall have any right or claim under this Section 9(a) with respect to the Maximum Liability, except to the extent necessary so that the obligations of the Subsidiary Guarantor hereunder shall not be rendered voidable under applicable law. (b) Each of the Subsidiary Guarantors agrees that the Guaranteed Obligations may at any time and from time to time exceed the Maximum Liability of each Subsidiary Guarantor, and may exceed the aggregate Maximum Liability of all other Subsidiary Guarantors, without impairing 104

this Guaranty or affecting the rights and remedies of the Agent hereunder. Nothing in this Section 9(b) shall be construed to increase any Subsidiary Guarantor's obligations hereunder beyond its Maximum Liability. (c) In the event any Subsidiary Guarantor (a "Paying Subsidiary Guarantor") shall make any payment or payments under this Guaranty or shall suffer any loss as a result of any realization upon any collateral granted by it to secure its obligations under this Guaranty, each other Subsidiary Guarantor (each a "Non-Paying Subsidiary Guarantor") shall contribute to such Paying Subsidiary Guarantor an amount equal to such Non-Paying Subsidiary Guarantor's "Pro Rata Share" of such payment or payments made, or losses suffered, by such Paying Subsidiary Guarantor. For the purposes hereof, each Non-Paying Subsidiary Guarantor's "Pro Rata Share" with respect to any such payment or loss by a Paying Subsidiary Guarantor shall be determined as of the date on which such payment or loss was made by reference to the ratio of (i) such Non-Paying Subsidiary Guarantor's Maximum Liability as of such date (without giving effect to any right to receive, or obligation to make, any contribution hereunder) or, if such Non-Paying Subsidiary Guarantor's Maximum Liability has not been determined, the aggregate amount of all monies received by such Non-Paying Subsidiary Guarantor from the Principal after the date hereof (whether by loan, capital infusion or by other means) to (ii) the aggregate Maximum Liability of all Subsidiary Guarantors hereunder (including such Paying Subsidiary Guarantor) as of such date (without giving effect to any right to receive, or obligation to make, any contribution hereunder), or to the extent that a Maximum Liability has not been determined for any Subsidiary Guarantors, the aggregate amount of all monies received by such Subsidiary Guarantors from the Principal after the date hereof (whether by loan, capital infusion or by other means). Nothing in this Section 9 (c) shall affect any Subsidiary Guarantor's several liability for the entire amount of the Guaranteed Obligations (up to such Subsidiary Guarantor's Maximum Liability). Each of the Subsidiary Guarantors covenants and agrees that its right to receive any contribution under this Guaranty from a Non-Paying Subsidiary Guarantor shall be subordinate and junior in right of payment to all the Guaranteed Obligations. The provisions of this Section 9(c) are for the benefit of both the Agent and the Subsidiary Guarantors and may be enforced by any one, or more, or all of them in accordance with the terms hereof. SECTION 10. Application of Payments. All payments received by the Agent hereunder shall be applied by the Agent to payment of the Guaranteed Obligations in the following order unless a court of competent jurisdiction shall otherwise direct: (a) FIRST, to payment of all costs and expenses of the Agent incurred in connection with the collection and enforcement of the Guaranteed Obligations or of any security interest granted to the Agent in connection with any collateral securing the Guaranteed Obligations; (b) SECOND, to payment of that portion of the Guaranteed Obligations constituting accrued and unpaid interest and fees, pro rata among the Lenders and their Affiliates in accordance with the amount of such accrued and unpaid interest and fees owing to each of them; 105

(c) THIRD, to payment of the principal of the Guaranteed Obligations and the net early termination payments and any other Rate Management Obligations then due and unpaid from the Borrower to any of the Lenders or their Affiliates, pro rata among the Lenders and their Affiliates in accordance with the amount of such principal and such net early termination payments and other Rate Management Obligations then due and unpaid owing to each of them; and (d) FOURTH, to payment of any Guaranteed Obligations (other than those listed above) pro rata among those parties to whom such Guaranteed Obligations are due in accordance with the amounts owing to each of them. SECTION 11. Notices. All notices, requests and other communications to any party hereunder shall be given or made by telecopier or other writing and telecopied, or mailed or delivered to the intended recipient at its address or telecopier number set forth on the signature pages hereof or such other address or telecopy number as such party may hereafter specify for such purpose by notice to the Agent in accordance with the provisions of Article XIII of the Credit Agreement. Except as otherwise provided in this Guaranty, all such communications shall be deemed to have been duly given when transmitted by telecopier, or personally delivered or, in the case of a mailed notice sent by certified mail return-receipt requested, on the date set forth on the receipt (provided, that any refusal to accept any such notice shall be deemed to be notice thereof as of the time of any such refusal), in each case given or addressed as aforesaid. SECTION 12. No Waivers. No failure or delay by the Agent or any Lenders in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies provided in this Guaranty, the Credit Agreement, any Note, any Rate Management Transaction and the other Loan Documents shall be cumulative and not exclusive of any rights or remedies provided by law. SECTION 13. No Duty to Advise. Each of the Subsidiary Guarantors assumes all responsibility for being and keeping itself informed of the Principal's financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks that each of the Subsidiary Guarantors assumes and incurs under this Guaranty, and agrees that neither the Agent nor any Lender has any duty to advise any of the Subsidiary Guarantors of information known to it regarding those circumstances or risks. SECTION 14. Successors and Assigns. This Guaranty is for the benefit of the Agent and the Lenders and their respective successors and permitted assigns and in the event of an assignment of any amounts payable under the Credit Agreement, any Note, any Rate Management Transaction, or the other Loan Documents, the rights hereunder, to the extent applicable to the indebtedness so assigned, shall be transferred with such indebtedness. This Guaranty shall be binding upon each of the Subsidiary Guarantors and their respective successors and permitted assigns. 106

SECTION 15. Changes in Writing. Neither this Guaranty nor any provision hereof may be changed, waived, discharged or terminated orally, but only in writing signed by each of the Subsidiary Guarantors and the Agent with the consent of the Required Lenders. SECTION 16. Costs of Enforcement. Each of the Subsidiary Guarantors agrees to pay all costs and expenses including, without limitation, all court costs and attorneys' fees and expenses paid or incurred by the Agent or any Lender or any Affiliate of any Lender in endeavoring to collect all or any part of the Guaranteed Obligations from, or in prosecuting any action against, the Principal, the Subsidiary Guarantors or any other guarantor of all or any part of the Guaranteed Obligations. SECTION 17. GOVERNING LAW; SUBMISSION TO JURISDICTION; WAIVER OF JURY TRIAL. THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF OKLAHOMA. EACH OF THE SUBSIDIARY GUARANTORS HEREBY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF OKLAHOMA AND OF ANY OKLAHOMA STATE COURT SITTING IN TULSA, OKLAHOMA AND FOR PURPOSES OF ALL LEGAL PROCEEDINGS ARISING OUT OF OR RELATING TO THIS GUARANTY (INCLUDING, WITHOUT LIMITATION, ANY OF THE OTHER LOAN DOCUMENTS) OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH OF THE SUBSIDIARY GUARANTORS IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH ANY OF THEM MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. EACH OF THE SUBSIDIARY GUARANTORS, AND THE AGENT AND THE LENDERS ACCEPTING THIS GUARANTY, HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS GUARANTY OR THE TRANSACTIONS CONTEMPLATED HEREBY. SECTION 18. Taxes. etc. All payments required to be made by any of the Subsidiary Guarantors hereunder shall be made without setoff or counterclaim and free and clear of and without deduction or withholding for or on account of, any present or future taxes, levies, imposts, duties or other charges of whatsoever nature imposed by any government or any political or taxing authority thereof (but excluding Excluded Taxes), provided, however, that if any of the Subsidiary Guarantors is required by law to make such deduction or withholding, such Subsidiary Guarantor shall forthwith (i) pay to the Agent or any Lender, as applicable, such additional amount as results in the net amount received by the Agent or any Lender, as applicable, equaling the full amount which would have been received by the Agent or any Lender, as applicable, had no such deduction or withholding been made, (ii) pay the full amount deducted to the relevant authority in accordance with applicable law, and (iii) furnish to the Agent or any Lender, as applicable, certified copies of official receipts evidencing payment of such withholding taxes within 30 days after such payment is made. 107

In view of the foregoing, the Borrower agrees that the Agent may at any time and from time to time, if a Default has occurred and is continuing, compromise with the obligor on any Receivable, accept in full payment of any Receivable such amount as the Agent in its sole discretion shall determine or abandon any Receivable, and any such action by the Agent shall be commercially reasonable so long as the Agent acts in good faith based on information known to it at the time it takes any such action. 8.3. Secured Party Performance of Debtor Obligations. Without having any obligation to do so, the Agent may perform or pay any obligation which the Borrower has agreed to perform or pay in this Security Agreement and the Borrower shall reimburse the Agent for any 138

Specific Performance of Certain Covenants. The Borrower acknowledges and agrees that a breach of any of the covenants contained in Sections 4.1.5, 4.1.6, 4.4, 5.3, or 8.7 or in Article VII will cause irreparable injury to the Agent and the Lenders, that the Agent and Lenders have no adequate remedy at law in respect of such breaches and therefore agrees, without limiting the right of the Agent or the Lenders to seek and obtain specific performance of other obligations of the Borrower contained in this Security Agreement, that the covenants of the Borrower contained in the Sections referred to in this Section 8.5 shall be specifically enforceable against the Borrower. 8.6.

The Grantor and the Agent recognize that setoffs, counterclaims, defenses and other claims may be asserted by obligors with respect to certain of the Receivables, that certain of the Receivables may be or become uncollectible in whole or in part and that the expense and probability of success in litigating a disputed Receivable may exceed the amount that reasonably may be expected to be recovered with respect to a Receivable. In view of the foregoing, the Grantor agrees that the Agent may at any time and from time to time, if a Default has occurred and is continuing, compromise with the obligor on any Receivable, accept in full payment of any Receivable such amount as the Agent in its sole discretion shall determine or abandon any Receivable, and any such action by the Agent shall be commercially reasonable so long as the Agent acts in good faith based on information known to it at the time it takes any such action. 163

SCHEDULE 11 ENVIRONMENTAL DISCLOSURES (See Section 5.16) Matrix is a participant in certain environmental activities in various stages involving assessment studies, cleanup operations and/or remedial processes. In connection with the Company's sale of Brown and affiliated entities in 1999, an environmental assessment was conducted at Brown's Newnan, Georgia facilities. The assessment turned up a number of deficiencies relating to storm water permitting, air permitting and waste handling and disposal. An inspection of the facilities also showed friable asbestos that needed to be removed. In addition, Phase II soil testing indicated a number of volatile organic compounds, semi-volatile organic compounds and metals above the state of Georgia notification limits. Ground water testing also indicated a number of contaminants above the State of Georgia notification limits. Appropriate State of Georgia agencies have been notified of the findings and corrective and remedial actions have been completed, are currently underway, or plans for such actions have been submitted to the State of Georgia for approval on the remaining property. The current estimated total cost for cleanup and remediation is $2,100,000, $100,000 of which remains accrued at May 31, 2002. Additional testing, however, could result in greater costs for cleanup and remediation than is currently accrued. Matrix closed or sold the business operations of its San Luis Tank Piping Construction Company, Inc. and West Coast Industrial Coatings, Inc. subsidiaries, which are located in California. Although Matrix does not own the land or building, it would be liable for any environmental exposure while operating at the facility, a period from June 1, 1991 to the present. At the present time, the environmental liability that could result from the testing is unknown, however, Matrix has purchased a pollution liability insurance policy with $5,000,000 of coverage for all operations. 199
