Once determined, the Libor Rate shall remain unchanged during the applicable Libor Rate Interest Period. "Libor Rate Basis" means, for any Libor Rate Interest Period, the interest rate per annum (rounded upward to the nearest 1/16th of one percent) determined by Bank at approximately 9:00 a.m., on the date which is three Business Days before the first day of such Libor Rate Interest Period to be the offered quotations that appear on the Reuter's Screen LIBO page for dollar deposits in the London interbank market for a length of time approximately equal to the Libor Rate Interest Period for the Libor Rate Election sought by Borrower. If at least two such offered quotations appear on the Reuter's Screen LIBO page, the Libor Rate shall be the arithmetic mean (rounded upward to the nearest 1/16th of one percent) of such offered quotations, as determined by Bank. If the Reuter's Screen LIBO page is not available or has been discontinued, the Libor Rate Basis shall be the rate per annum that Bank determines to be the arithmetic mean (rounded as aforesaid) of the per annum rates of interest at which deposits in dollars in an amount approximately equal to the principal amount of, and for a length of time approximately equal to the Libor Rate Interest Period for, the Libor Rate Election sought by Borrower are offered to Bank in immediately available funds in the London interbank market at 11:00 a.m., London time, on the date which is three Business Days prior to the first day of a Libor Rate Interest Period. -3- 4 "Libor Rate Election" means an election by Borrower, as hereinafter provided, to cause a portion of the previously advanced proceeds of the Loan to be segregated into a separate account and bear interest at the Libor Rate, rather than the Stated Rate for the term of the Election.

"Prime Rate" means, on any day, the rate of interest per annum then most recently established by Bank as its "prime rate." Such rate is set by Bank as a general reference rate of interest, taking into account such factors as Bank may deem appropriate, it being understood that it is not necessarily the lowest or best rate actually charged to any customer or a favored rate, that it may not correspond with future increases or decreases in interest rates charged by other lenders or market rates in general and that Bank may make various business or other loans at rates of interest having no relationship to such rate.

"Stated Rate" means, on any day, a variable rate per annum equal to the Prime Rate for that day computed using the 365/360 method described below provided, that if on any day the Stated Rate shall exceed the maximum permitted by application of the Maximum Rate in effect on that day, the Stated Rate shall be fixed at the maximum permitted by application of the Maximum Rate on that day and on each day thereafter until the total amount of interest accrued at the Stated Rate on the unpaid balance of this Note equals the total amount of interest which would have accrued if there were no limitation by the Maximum Rate and the Stated Rate had not been so fixed, or until the earlier payment in full of this Note. "Stated Rate Loans" means, that portion of the principal balance this Note bearing interest at the Stated Rate prior to an Event of Default or maturity. 2. Maturity Date. The entire principal balance of this Note then unpaid together with all accrued and unpaid interest hereon shall be due and payable on March 13, 1998 (the "Maturity Date"). 3. Advances. This Note is a revolving promissory note evidencing a revolving line of credit, not to exceed $12,500,000.00 at any one time outstanding. While the aggregate of all advances under this Note may exceed $12,500,000.00, the outstanding balance of this Note at any one time shall not exceed $12,500,000.00. Before the Maturity Date, Borrower may borrow, repay and borrow principal amounts again up to $12,500,00.00, subject to the -5- 6 terms of this Note and Loan Agreement. Advances shall be made in accordance with the terms of the Loan Agreement. 4. Interest Rate(s). As hereinafter provided, prior to default or maturity, the principal balance of this Note may be segregated into separate accounts and shall bear interest as follows: (a) So much of the principal balance of this Note as is not from time to time subject to an effective Election shall constitute one account (the "Stated Rate Account") and shall bear interest prior to the occurrence of an Event of Default or maturity at the lesser of: (a) the Maximum Rate, or (b) the Stated Rate. (b) Each portion of the principal balance hereof which may from time to time be subject to an effective CD Rate Election shall constitute a separate account (the "CD Funds Account") and shall bear interest prior to the occurrence of an Event of Default or maturity at the lesser of: (a) the Maximum Rate, or (b) the CD Rate applicable to such Election. (c) Each portion of the principal balance hereof, which may from time to time be subject to an effective Libor Rate Election shall constitute a separate account (the "Libor Rate Account") and shall bear interest prior to an Event of Default or maturity at the lesser of: (a) the Maximum Rate, or (b) the Libor Rate applicable to such Election. 5. Past Due Interest. After the earlier of an Event of Default on the Maturity Date, the entire unpaid principal balance of and to the extent permitted by applicable law any interest on, this Note shall bear interest at a varying rate per annum equal to the lesser of (a) the Maximum Rate, or (b) the Default Rate. 6. 365/360 Method; Rate Fluctuations. Subject always to limitation by the Maximum Rate, interest on this Note at the Stated Rate and the Default Rate shall be calculated on the basis of the 365/360 method, which computes a daily amount of interest for a hypothetical year of 360 days, then multiplies such amount by the actual number of days elapsed in an interest calculation period. Without notice to Borrower or anyone else, the Prime Rate and the Maximum Rate shall each automatically fluctuate upward and downward as and in the amount by which Bank's prime rate and such maximum nonusurious rate of interest permitted by applicable law, respectively, fluctuate, subject always to limitation of the Stated Rate and the Default Rate by the Maximum Rate. 7. Interest Periods. The term "Interest Period" as used in this Note means the time from and including the first (1st) day of each calendar month (each such date being called a "Payment Date") through the end of the day before the next occurring Payment Date, except that (a) the first Interest Period is the period from and including the day the first proceeds of this Note are disbursed through the end of the day before the first -6- 7 occurring Payment Date and (b) the last Interest Period is the period from and including the day after the end of the next-to-last Interest Period through the end of the day before the maturity of this Note (whether resulting from demand for payment, the passage of time, acceleration for default, or any permitted prepayment). The interest accruing prior to the occurrence of an Event of Default or maturity on the Stated Rate Account shall be calculated by first determining the amount of interest on the unpaid principal balance of the Stated Rate Account from time to time outstanding at the Stated Rate in effect from time to time from the date hereof through the end of each Interest Period (or, if the Note has matured, through the end of the day before maturity), then deducting any interest previously paid on the Stated Rate Account to determine the amount of interest then payable; provided, however, that the total interest payable on the Stated Rate Account through the end of each Interest Period and at maturity shall not exceed the maximum amount of interest that may be lawfully charged on the Stated Rate Account from the date hereof through such date. The interest accruing prior to the occurrence of an Event of Default or maturity on the principal balance of each Matching Funds Account shall be calculated by determining the amount of interest on the unpaid principal balance of such Matching Funds Account from time to time outstanding at the Matching Funds Rate applicable to such Matching Funds Account in effect from time to time (which Matching Funds Rate shall never exceed the maximum lawful rate applicable thereto), and such interest shall be payable at the times and in the manner as herein provided for the Stated Rate Account. 8. Interest Payments. Interest for each Interest Period during the term of this Note shall be calculated as of the end of such Interest Period and, except as hereinafter expressly provided to the contrary, shall be payable on or before the first day of the following Interest Period and, in the case of the last Interest Period, at maturity. Whenever any payment shall be due under this Note on a day which is not a Business Day, the date on which such payment is due shall be extended to the next succeeding Business Day, and such extension of time shall be included in the computation of the amount of interest then payable. All principal, interest and other sums payable under this Note shall be paid, not later than 2:00 o'clock p.m. (Dallas, Texas time) on the day when due, in immediately available funds in lawful money of the United States of America. Any payment under this Note or under any other Loan Document other than in the required amount in good, unrestricted U.S. funds immediately available to the holder hereof shall not, regardless of any receipt or credit issued therefor, constitute payment until the required amount is actually received by the holder hereof in such funds and shall be made and accepted subject to the condition that any check or draft may be handled for collection in accordance with the practice of the collecting bank or banks. 9. Application of Payments. All payments made as scheduled on this Note shall be applied, to the extent thereof, first to accrued but unpaid interest and the balance to unpaid principal. All prepayments on this Note made prior to an Event of Default shall be applied, to the extent thereof, first to accrued but unpaid interest and the balance to the remaining principal installments in inverse order of their maturity. Nothing herein shall limit or impair any rights of the holder hereof to apply any past due payments, any proceeds from -7- 8 the disposition of any collateral by foreclosure or other collections after an Event of Default to the amounts owing hereunder in such manner as Bank shall elect. Except to the extent specific provisions are set forth in this Note or another Loan Document with respect to application of payments, all payments received by the holder hereof shall be applied in such order and manner as the holder hereof shall deem appropriate, any instructions from Borrower or anyone else to the contrary notwithstanding. 10. Matching Funds Election. From time to time during the term of the Loan, so long as no Event of Default has occurred and is continuing, Borrower may elect to cause a portion or portions of the Loan proceeds previously disbursed to Borrower, which portions must be at least $500,000.00 each, to bear interest at the CD Rate or the Libor Rate, as applicable, rather than the Stated Rate; provided, however, that Borrower may not exercise a Matching Funds Election at any time when the applicable Matching Funds Rate would exceed the maximum lawful rate of interest applicable to the Loan. Upon the effective date of each Election, the portion of the Loan proceeds as to which the Election is exercised shall be segregated into a separate account (the CD Funds Account or the Libor Rate, as the case may be) and shall bear interest prior to the occurrence of an Event of Default or maturity from the effective date of the Election to the end of the term CD Interest Period or Libor Rate Interest Period, as applicable, at the CD Rate or the Libor Rate, as applicable, in effect on the effective date of the Election; provided that CD Rates shall be adjusted from time to time during the term of any CD Rate Election to account for any fluctuations in the CD Reserve Requirement, insurance, fees, assessments and surcharges, and the Libor Rate, as applicable, shall be adjusted from time to time during the term of any Libor Rate Election, as applicable, to account for fluctuations in reserve percentages, insurance, fees, assessments and surcharges. 11. Exercise of Elections. Borrower shall inform Bank when Borrower wishes to exercise a Matching Funds Election, specifying a CD Rate Election or a Libor Rate Election is requested, and Bank shall advise Borrower of the Matching Funds Rate applicable to such Election and the periods for which Borrower may exercise such Election. To exercise a CD Rate Election, Borrower shall advise Bank of (a) the amount of the Matching Funds Principal as to which Borrower wishes to exercise such CD Rate Election, and (b) the desired term of such CD Rate Interest Period. A CD Rate Election shall become effective three (3) Business Days following the date of Borrower's advising Bank of the particular terms of the CD Rate Election. To exercise a Libor Rate Election, Borrower shall advise Bank of (a) the amount of the Matching Funds Principal as to which Borrower wishes to exercise such a Libor Rate Election, and (b) the desired term of such Libor Rate Interest Period. A Libor Rate Election shall be effective three (3) Business Days following the date of Borrower's advising Bank of the particular terms of the Libor Rate Election. On or before the effective date of each Election, Borrower shall execute and deliver to Bank a written confirmation of (a) the amount of the Matching Funds Principal subject to the Election, (b) the term of the Election, and (c) the initial Matching Funds Rate applicable to such Election. -8- 9 12. Extension of Elections. Borrower may not extend a Matching Funds Election beyond the original term thereof at the Matching Funds Rate applicable during the original term. However, at the end of the term of a Matching Funds Election, Borrower may make an additional Matching Funds Election to cause the Matching Funds Principal subject to the expired Election to bear interest at the Matching Funds Rate applicable on the day after the expiration of the prior Election for the term of the new Election by so advising Bank three (3) Business Days before the expiration of a CD Rate Election or Libor Rate Election, as applicable, and Bank shall advise Borrower of the Matching Funds Rate available to Borrower for such new Election, and Borrower shall give to Bank a written confirmation by the effective date of the new Election in the manner specified in the preceding paragraph, accompanied by the payment of any additional fee required by this Note. Otherwise, upon the expiration of the prior Election, the Matching Funds Principal subject to the expired Election shall be returned to the same account as the Loan proceeds which bear interest at the Stated Rate and shall again bear interest prior to the occurrence of an Event of Default or maturity at the Stated Rate. 13. Change of Law; Impracticability of Election. Notwithstanding any other provision of this Note, if: (a) any change in applicable law, rule or regulation or in the interpretation or administration thereof shall make it unlawful for Bank to issue certificates of deposit or impair or restrict Bank's ability to do so for terms and at rates which would permit Bank to respond to a Matching Funds Election by obtaining funds at the CD Rate, or the Libor Rate, as applicable, or (b) deposits in funds in the applicable amounts against which Bank is to match Matching Funds Principal in connection with an Election are not being offered generally to Bank in the relevant market for the applicable period, or (c) the CD Rate or the Libor Rate, as applicable, will not accurately and fairly reflect the cost to Bank of funding a CD Rate Election or Libor Rate Election, as applicable, then, in the case of (a),(b) or (c) above, any of the foregoing instances, Borrower's right to make any further Matching Funds Elections or to continue any Matching Funds Election then in force shall be suspended for the duration of such illegality or impairment or restriction. If Bank makes such determination, it shall promptly notify Borrower in writing, and Borrower shall either repay the outstanding Matching Funds Election owed to Bank, without penalty, within thirty (30) days or convert the same to Stated Rate Loans within thirty (30) days. So long as Bank has given Borrower the notice required by the preceding sentence, Borrower shall indemnify and hold harmless Bank against all costs, claims, penalties, liabilities and damages which may result from any such change in law, rule, regulation, interpretation or administration. 14. Limitation on Matching Funds Interest. It is expressly understood that all provisions of this Note, including but not limited to the provisions regarding the charging of interest at a Matching Funds Rate for the term of a Matching Funds Election, are subject to the provisions hereof limiting the amount of interest contracted for, charged, or collected hereunder to the maximum amount permitted under applicable law. 15. Prepayment. Except as otherwise specifically provided in this Note, Borrower shall have the right to prepay the outstanding principal balance of this Note, in full at any -9- 10 time or in part from time to time without premium or penalty, provided, that as conditions precedent to Borrower's right to make, and Bank's obligations to accept, any such prepayment for any portion of the principal balance of this Note subject to a Matching Funds Election: (i) Bank shall have actually received from Borrower at least five (5) business days' prior written notice of Borrower's intent to prepay, of the amount of principal which will be prepaid (the "Prepaid Principal") and of the date (the "Prepayment Date") on which the prepayment will be made; (ii) each prepayment of principal shall be in the amount of $50,000 or a larger multiple of $1,000.00 (unless the prepayment retires the outstanding balance of this Note in full); (iii) each such prepayment shall be in the amount of 100% of the principal amount to be prepaid, plus accrued unpaid interest thereon to the Prepayment Date, plus any other sums which have become due to Bank under the Loan Documents on or before the Prepayment Date but have not been paid; and (iv) plus if any portion of this Note subject to a Matching Funds Election is prepaid, the Make-Whole Amount (hereinafter defined) if the Treasury Rate (hereinafter defined) plus the Closing Spread (hereinafter defined) is less than per annum interest rate of the Matching Fund Principal being prepaid (the "Loan Interest Rate"), except as provided in Section 2.4 of the Loan Agreements. The "Make-Whole Amount" shall equal (i) the sum of the amounts calculated by discounting the Remaining Scheduled Payments (hereinafter defined) from their respective scheduled due dates to the Prepayment Date, in accordance with accepted financial practice at a discount factor equal to the Treasury Rate plus the Closing Spread, less (ii) the Prepaid Principal; but the Make-Whole Amount shall in no event be less than zero and nothing herein shall be construed or operate to require Borrower to pay a Make-Whole Amount except in connection with Borrower's exercise of the right to prepay granted above or to pay any amount greater than is permitted by applicable law. If a Make-Whole Amount will be due, Bank shall notify Borrower of the amount and basis of determination of the Make-Whole Amount. For the purposes of determining the Make-Whole Amount, the following terms shall have the following meanings: The "Treasury Rate" is the yield on the Treasury Constant Maturity Series with maturity equal to the remaining weighted average life to maturity of the Remaining Scheduled Payments which are principal payments (calculated as of the Prepayment Date in accordance with accepted financial practice and rounded to the nearest quarter-year), as reported in Federal Reserve Statistical Release H.15 (519) - Selected Interest Rates, in the "This Week" column of the issue which, as of the fifth business day before the Prepayment Date, has been most recently published. If no maturity exactly corresponding to such remaining weighted average life to maturity appears in Release H.15, the Treasury Rate will be determined by liner interpolation between the yields reported in Release H.15. If for any reason Release H.15 is not longer -10- 11 published, Bank shall select a comparable publication to determine the Treasury Rate. The "Remaining Scheduled Payments" are (i) each scheduled payment of principal of this Note which is, or to the extent that it is, paid before its scheduled due date by application of the Prepaid Principal [in inverse order of maturity of installments of principal] in accordance with this Note; and (ii) each scheduled payment of interest on the Prepaid Principal that would be due in accordance with this Note after the Prepayment Date if no payment of the Prepaid Principal were made prior to its scheduled due date(s). The "Closing Spread" is the difference between the Loan Interest Rate and the Treasury Rate with such Treasury Rate being calculated as of the date of this Note, as if the principal face amount of this Note were the Prepaid Principal and the date of this Note were the Prepayment Date. Borrower agrees that Bank shall not be obligated actually to reinvest the amount prepaid in any Treasury obligations as a condition to receiving the Make-Whole Amount or otherwise. All prepayments of principal shall be applied to principal in inverse order of maturity. 16. Reimbursement of Losses Arising from Deviations in Payment of Matching Funds Elections. If Borrower makes any payment of principal with respect to any CD Rate Election or Libor Rate Election on any day other than the last day of an Election or if Borrower fails to convert any portion of the Loan bearing interest at the Stated Rate to a CD Rate Election or Libor Rate Election after notice has been given to Bank in accordance with the terms hereof, Borrower shall reimburse Bank on demand for any resulting loss or expense incurred by Bank (or by any existing or prospective participant in the related CD Rate Election or Libor Rate Election), including, without limitation, any loss incurred in obtaining, liquidating, or redeploying deposits from third parties, but excluding loss of margin for the period after any such payment or failure to borrow, provided that Bank shall have delivered to Borrower a certificate as to the amount of such loss or expense and the basis for determining such amount. Determinations by Bank of amounts due under this Section 16 shall be conclusive, absent manifest error. 17. Reserve Requirements. In the event of any change in any applicable law, treaty, or regulation or in the interpretation or administration thereof or in the event any central bank or other fiscal monetary or other authority having jurisdiction over Bank or the Loan contemplated by this Note imposes, modifies, or deems applicable to any CD Rate Elections or Libor Rate Elections any reserve requirement of the Board of Governors of the Federal Reserve System or any other reserve, special deposit, or similar requirements against assets of, deposits with or for the account of, or credit extended by, Bank, or imposes on Bank any other condition affecting this Note or the CD Rate Elections or Libor Rate Elections and the result of any of the foregoing is to increase the cost to Bank in making or -11- 12 maintaining its CD Rate Elections or Libor Rate Elections or to reduce any amount (or the effective return on any amount) received by Bank hereunder, then Borrower shall pay to Bank upon demand of Bank as additional interest on this Promissory Note such additional amount or amounts as Bank may determine as will reimburse Bank for such additional cost or such reduction. Upon becoming aware of any such change or imposition that may result in any such increase or reduction, Bank shall give written notice to Borrower thereof together with certificate of Bank setting forth the amount necessary to compensate Bank as aforesaid and the basis for the determination of such amount and Borrower shall, within thirty (30) days, either (i) promptly pay such amount, (ii) convert such Matching Funding Election to a Stated Rate Loan, or (iii) prepay the Matching Funds Election without penalty. Determinations made by Bank for purposes of this Section 17 of the effect of any such change in its costs of making or maintaining its Matching Funds Elections or on amounts receivable by it in respect or such Matching Funds Elections and of the additional amounts required to compensate Bank in respect thereof shall be conclusive, absent manifest error. 18. Taxes. If any taxes are levied or imposed on or with respect to the CD Funds Account and/or the Libor Rate Account or on any payment on the CD Funds Account and/ or the Libor Rate Account made to Bank, then, and in any such event, Borrower shall pay to Bank upon demand of Bank such additional amounts as Bank may determine to be necessary so that every net payment of principal and interest on the CD Funds Account and/or the Libor Rate Account, after withholding or deduction for or on account of any such taxes, will not be less than any amount provided herein. In addition, if at any time when the Matching Funds Elections are outstanding any laws are enacted or promulgated, or any court of law or governmental agency interprets or administers any law, which, in any such case, changes the basis of taxation of payments to Bank of principal of or interest on the CD Funds Account and the Libor Rate Account by subjecting such payments to double taxation or otherwise (except through an increase in the rate of tax on the overall net income of Bank) then Borrower, within thirty (30) days will either (i) pay Bank such amounts as Bank may determine to be necessary to compensate Bank for any such increased costs and/or losses resulting therefrom, (ii) convert the balance of any Matching Funds Elections to Stated Rate Loans, or (iii) prepay any Matching Funds Elections without penalty. Bank shall give notice to Borrower upon becoming aware of the amount of any loss incurred by it through enactment or promulgation of any such law that changes the basis of taxation of payments to Bank or of any such enactment or promulgation that may result in such payments becoming subject to double taxation or otherwise. Bank shall also deliver to Borrower a certificate of Bank setting forth the basis for the determination of such loss and the computation of such amounts. Determinations made by Bank for purposes of this Section 18 of the effect of such taxes on its costs of making or maintaining Matching Funds Elections or on amounts receivable by it in respect of such Matching Funds Elections and of the additional amounts required to compensate Bank in respect thereof shall be conclusive, absent manifest error. 19. Illegality, Change in Laws, Etc.

No Waiver. Neither the failure by the holder hereof to exercise, nor delay by the holder hereof in exercising, the right to accelerate the maturity of this Note or any other right, power or remedy upon any default shall be construed as a waiver of such default or as a waiver of the right to exercise any such right, power or remedy at any time. No single or partial exercise by the holder hereof of any right, power or remedy shall exhaust the same or shall preclude any other or further exercise thereof, and every such right, power or remedy may be exercised at any time and from time to time.

Limitation on Interest. It is the intent of Bank and Borrower and all other parties to the Loan Documents to conform to and contract in strict compliance with applicable usury law from time to time in effect. All agreements between Bank or any other holder hereof and Borrower (or any other party liable with respect to any indebtedness under the Loan Documents) are hereby limited by the provisions of this paragraph which shall override and control all such agreements, whether now existing or hereafter arising and whether written or oral. In no way, nor in any event or contingency (including but not limited to prepayment, default, demand for payment, or acceleration of the maturity of any obligation), shall the interest taken, reserved, contracted for, charged or received under this Note or otherwise, exceed the maximum nonusurious amount permissible under applicable law. If, from any possible construction of any document, interest would otherwise be payable in excess of the maximum nonusurious amount, any such construction shall be subject to the -14- 15 provisions of this paragraph and such document shall be automatically reformed and the interest payable shall be automatically reduced to the maximum nonusurious amount permitted under applicable law, without the necessity of execution of any amendment or new document. If the holder hereof shall ever receive anything of value which is characterized as interest under applicable law and which would apart from this provision be in excess of the maximum nonusurious amount, an amount equal to the amount which would have been excessive interest shall, without penalty, be applied to the reduction of the principal amount owing on the indebtedness evidenced hereby in the inverse order of its maturity and not to the payment of interest, or refunded to Borrower or the other payor thereof if and to the extent such amount which would have been excessive exceeds such unpaid principal. The right to accelerate maturity of this Note or any other indebtedness does not include the right to accelerate any interest which has not otherwise accrued on the date of such acceleration, and the holder hereof does not intend to charge or receive any unearned interest in the event of acceleration. All interest paid or agreed to be paid to the holder hereof shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full stated term (including any renewal or extension and including the term of the Prior Note of such indebtedness so that the amount of interest on account of such indebtedness does not exceed the maximum nonusurious amount permitted by applicable law. As used in this paragraph, the term "applicable law" shall mean the laws of the State of Texas or the federal laws of the United States, whichever laws allow the greater interest, as such laws now exist or may be changed or amended or come into effect in the future. 26.
