The Bank agrees to renew, extend and increase the Revolving Loan established under the Existing Loan Agreement and to make Revolving Advances thereunder to the Borrower from time to time during the Commitment Period in an aggregate amount at any time outstanding not to exceed the Revolving Commitment. The Borrower may request Revolving Advances from time to time under the Revolving Loan in accordance with the provisions of Subsection 2.3 hereof, and may prepay and re-borrow on a revolving basis; provided, however, that the aggregate principal amount of all Revolving Advances at any time outstanding under the Revolving Loan shall not exceed the lesser of (i) the Revolving Commitment as in effect on such date, and (ii) the Borrowing Base as in effect on such date.

Subject to the Borrower's satisfaction of all other conditions precedent as set forth in Subsection 4.3 hereof, each Revolving Advance will be made on the same Business Day on which the Bank receives the Borrower's Disbursement Request, if the Disbursement Request is received by 1:00 p.m., or on the following Business Day, if it is received after 1:00 p.m. The Bank will make each Revolving Advance by crediting the general operating account maintained by the Borrower with the Bank. 2.4 Revolving Note. The Revolving Advances from time to time outstanding under the Revolving Loan (including amounts advanced under the Existing Loan Agreement) will be evidenced by the Revolving Note, which shall be made and delivered by the Borrower at or prior to the Effective Date. Notwithstanding the principal amount stated on the face of the Revolving Note, the actual principal due from the Borrower on account of the Revolving Note will be the sum of all Revolving Advances from time to time made by the Bank (including amounts advanced under the Existing Loan Agreement), less all principal payments actually received by the Bank in collected funds. Each Revolving Advance and each principal payment under the Revolving Loan will be recorded by the Bank in its books and records, and the unpaid principal balance so recorded will be presumptive evidence of the principal amount owing under the Revolving Note. 2.5 Interest. 2.5.1 Rate. The unpaid principal amount of the Revolving Advances from time to time outstanding under the Revolving Note will bear interest at a fluctuating rate per annum equal to the Prime Rate, plus the Applicable Margin; provided, however, that, upon the occurrence of any Event of Default and until cured to the satisfaction of the Bank, the unpaid principal amount of all Revolving Advances from time to time outstanding under the Revolving Note will bear interest at a fluctuating rate per annum equal to the Prime Rate (but not less than the Prime Rate in effect on the date of the occurrence of the Event of Default), plus five (5) percentage points. The interest rate payable under the Revolving Note will be adjusted as of the opening of business on the day of each change in the Prime Rate and as of the first day of the fiscal quarter following any change in the Applicable Margin. 2.5.2 Payment. Interest shall be due and payable monthly in arrears on the last day of each calendar month commencing November 30, 1996, and on the Maturity Date. 2.5.3 Computation of Interest. Interest on the Revolving Advances outstanding under the Revolving Note shall be computed on the basis of a year consisting of 360 days and for the actual number of days elapsed. 2.6 Non-Use Fee. The Borrower will pay the Bank a "Non-Use Fee" calculated at the rate of one half of one percent (0.5%) per annum on the average daily unborrowed amount of the Revolving Commitment, payable monthly in arrears on the first day of each month beginning on December 1, 1996, with final payment being due and payable on the Maturity Date. The calculation of the "Non-Use Fee" will be based upon a year consisting of 360 days and for the actual number of days elapsed. 2.7 Principal Payments. 2.7.1 Maturity. The entire outstanding principal balance of the Revolving Note, together with all unpaid interest accrued thereon, shall be due and payable in full on the Maturity Date. 2.7.2 Clean-Down Periods. At least once during each fiscal year of the Borrower, the Borrower shall designate a period of thirty (30) consecutive calendar days as a "Clean- Down Period." During each Clean-Down Period: (a) the aggregate outstanding Revolving Advances shall not exceed the sum of $850,000.00; and (b) the Borrower shall not request, and the Bank shall not be obligated to make, any new Revolving Advances if the making of such Revolving Advances would cause the aggregate outstanding Revolving Advances to exceed $850,000.00. 2.7.3 Mandatory Prepayments. If the principal balance of the Revolving Advances outstanding under the Revolving Note at any time exceeds the Borrowing Base then in effect, the Borrower shall make an immediate mandatory prepayment of principal on the Revolving Note in an amount equal to the excess. 2.8 Optional Prepayment. The Borrower may, from time to time, prepay the outstanding principal amount of the Revolving Note, in whole or in part, without premium or penalty. 2.9 Making of Payments. All payments, including prepayments, of principal or interest on the Revolving Note shall be made to the Bank at its principal office in Oklahoma City, Oklahoma, on or before 2:00 p.m., on the date due in immediately available funds. Whenever a payment is due on a day other than a Business Day, the due date shall be extended to the next succeeding Business Day and interest (if any) shall accrue during such extension. 2.10 Maximum Lawful Interest Rate. It is not the intention of the Bank or the Borrower to violate the Laws of any applicable jurisdiction relating to usury or other restrictions on the maximum lawful interest rate. The Loan Documents and all other agreements between the Borrower and the Bank, whether now existing or hereafter arising and whether written or oral, are hereby limited so that in no event shall the interest paid or agreed to be paid to the Bank for the use, forbearance or detention of money loaned, or for the payment or performance of any covenant or obligation contained herein or in any other Loan Document, exceed the maximum amount permissible under applicable law. If from any circumstances whatsoever fulfillment of any provision hereof or of any other Loan Document, at the time the performance of such provision shall be due, shall involve transcending the limit of validity prescribed by law, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit of such validity. If from any such circumstances the Bank shall ever receive anything of value deemed interest under applicable law which would exceed interest at the highest lawful rate, such excessive interest shall be applied to the reduction of the principal amount owing hereunder, and not to the payment of interest, or if such excessive interest exceeds any unpaid balance of principal, such excess shall be refunded to the Borrower. All sums paid or agreed to be paid to the Bank for the use, forbearance or detention of monies included in the Loans shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of such indebtedness until payment in full so that the rate of interest on account of such indebtedness is uniform throughout the term thereof. This Subsection 2.10 shall control every other provision of the Loan Documents and all other agreements between the Bank and the Borrower contemplated thereby. 2.11 Renewal and Extension. The parties anticipate that the Bank may from time to time, in its sole and absolute discretion, extend the Maturity Date (and thereby extend the Commitment Period) upon request by the Borrower. The Bank shall not be obligated to extend the Maturity Date at any time, and the Borrower acknowledges that the Bank has not made any commitment, written or oral, concerning extension of the Maturity Date. In the event the Maturity Date is extended, the terms and provisions of this Agreement will continue in full force and effect, except as may otherwise be agreed in writing by the Borrower and the Bank. 2.12 Reduction of Revolving Commitment. The Borrower may at any time or from time to time permanently reduce the amount of the Revolving Commitment by giving notice of the amount of such reduction to the Bank and prepaying the amount by which the principal balance of the then outstanding Revolving Advances exceeds the reduced amount of the Revolving Commitment. Further, the Borrower may terminate the Revolving Commitment at any time by giving notice of such termination to the Bank and paying the entire principal balance of the Revolving Note and all unpaid interest, fees and other charges accrued in respect of the Revolving Loan. 3. SECURITY. As security for the prompt payment and performance of the Indebtedness, at all times during the term of this Agreement and until the Indebtedness is paid and satisfied in full: 3.1 Collateral. The Borrower will maintain and continue in favor of the Bank a valid and perfected security interest in and to the Collateral, which security interest shall be first and prior to all other Liens.

REMEDIES UPON DEFAULT. 9.1 Termination of Revolving Commitment. Upon the occurrence of any Event of Default specified in Subsection 8.5 hereof, the Revolving Commitment and the obligation of the Bank hereunder to make Revolving Advances will automatically be terminated. Upon the occurrence of any other Event of Default, the Bank may, at its option, without notice or demand, terminate the Revolving Commitment and its obligation to make further Revolving Advances. 9.2 Acceleration of Indebtedness. Upon the occurrence of any Event of Default specified in Subsection 8.5 hereof, the Revolving Note and all other Indebtedness will become immediately due and payable, without notice or demand. Upon the occurrence of any other Event of Default, the Bank may, at its option, without notice or demand, declare the Revolving Note and all other Indebtedness to be immediately due and payable. 9.3 Remedies. Upon the occurrence and during the continuation of any Event of Default, the Bank will be entitled to exercise all remedies available to it under the Loan Documents or otherwise under applicable law, including (i) exercising any and all rights under the Security Agreement and the UCC with respect to the Collateral, and (ii) commencing one or more actions against the Borrower or the Guarantor and reducing the claims of the Bank to judgment. 9.4 Cumulative Remedies. No failure on the part of the Bank to exercise, and no delay in exercising, any right or remedy under the Loan Documents will operate as a waiver thereof, nor will any single or partial exercise by the Bank of any right thereunder preclude any other or further right of exercise thereof or the exercise of any other right. The remedies provided herein and in the other Loan Documents are cumulative and not alternative. 9.5 Waiver of Default. The Bank may, by an instrument in writing, waive any Default or Event of Default and any of the consequences of such Default or Event of Default, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequence of such subsequent or other Default or Event of Default. 9.6 Deposits; Setoff. Regardless of the adequacy of any other collateral security held by the Bank, any deposits or other sums credited by or due from the Bank to the Borrower will at all times constitute collateral security for the Indebtedness and may be set off against the Indebtedness at any time, whether or not the Indebtedness has been declared immediately due and payable. The rights granted by this Subsection 9.6 are in addition to the rights of the Bank under any statutory banker's lien or the common law right of set off. This Subsection 9.6 shall not apply to any monies of which the Borrower is not the beneficial owner, regardless of the name in which the money is deposited, or to any monies which the Borrower is contractually obligated to spend in whole or in part for the account of others, provided that the Borrower has established special accounts or given the Bank written notice that particular funds are beneficially owned by others or are dedicated for particular expenditures. If the Borrower fails to establish such special accounts and fails to give such notice, the Bank may assume that funds on deposit to the account of the Borrower belong solely to the named depositor and are subject to this Subsection 9.6. 9.7 Application of Payments. During the continuation of any Event of Default, all payments received by the Bank with respect to the Indebtedness, whether from the Borrower, the Guarantor, recoveries upon the Collateral, or otherwise, may be applied by the Bank to any liabilities, obligations or indebtedness included in the Indebtedness selected by the Bank in its sole and exclusive discretion. 10.
