The outstanding principal balance hereof shall bear interest prior to maturity at a varying rate per annum which shall from day to day be equal to the lesser of (a) the maximum rate permitted by applicable law as the same exists from day to day during the term hereof ("Maximum Rate"), including, as to Article 5069-1.04, Vernon's Texas Civil Statutes (and as the same may be incorporated by reference in other Texas statutes), but otherwise without limitation, that rate based upon the "indicated rate ceiling" or (b) the sum of the Bank One Base Rate (hereinafter defined) of Payee in effect from day to day plus one-half of one percent (1/2%), each such change in the rate of interest charged hereunder to become effective, without notice to Maker, on the effective date of each change in the Bank One Base Rate; provided however, if at any time the rate of interest specified in clause (b) preceding shall exceed the Maximum Rate, thereby causing the interest rate hereon to be limited to the Maximum Rate, then any subsequent reduction in the Bank One Base Rate will not reduce the rate of interest hereon below the Maximum Rate until the total amount of interest accrued hereon equals the amount of interest which would have accrued hereon if the rate specified in clause (b) preceding had at all times been in effect. All past due principal and interest shall bear interest at the Maximum Rate. -------------- Initialled for Identification Page 1 of a 4 Page Note As used herein, the term "Bank One Base Rate" means, at any time the lesser of (i) the rate of interest per annum then most recently established by Payee as its Bank One Base Rate in effect from day to day, with each change in the rate of interest charged as the Bank One Base Rate to become effective, without notice to Maker, on the effective date of each change in the Bank One Base Rate, such Bank One Base Rate to be computed on the basis of a year composed of 365 days for the actual number of days elapsed (including the first day but excluding the last day) or (ii) the Maximum Rate (as herein defined).

Maker may prepay the principal of this note upon the terms and conditions specified in the Agreement. Notwithstanding anything to the contrary contained herein, no provisions of this note shall require the payment or permit the collection of interest in excess of the Maximum Rate. If any excess of interest in such respect is herein provided for, or shall be adjudicated to be so provided, in this note or otherwise in connection with this loan transaction the provisions of this paragraph shall govern and prevail, and neither Maker nor the sureties, guarantors, successors or assigns of Maker shall be obligated to pay the excess amount of such interest, or any other excess sum paid for the use, forbearance or detention of sums loaned pursuant hereto. If for any reason interest in excess of the Maximum Rate shall be deemed charged, required or permitted by any court of competent jurisdiction, any such excess shall be applied as a payment and reduction of the principal of indebtedness evidenced by this note; and, if the principal amount hereof has been paid in full, any remaining excess shall forthwith be paid to Maker. If default be made in the payment of principal or interest under this note and such default shall continue for three (3) Business Days after notice thereof to Maker pursuant to the Agreement, as defined in the Agreement, or upon the occurrence of any other Event of Default, as such term is defined in the Agreement, the holder hereof may, at its option, declare the entire unpaid principal of and accrued interest on this note immediately due and payable without additional notice, demand or presentment, all of which are hereby waived, and upon such declaration, the same shall become and shall be immediately due and payable, and the holder hereof shall have the right to foreclose or otherwise enforce all liens or security interests securing any sum or sums owed by the holder hereof to Maker. Failure of the holder hereof to exercise this option shall not constitute a waiver of the right to exercise the same upon the occurrence of a subsequent Event of Default. -------------- Initialled for Identification Page 2 of a 4 Page Note If the holder hereof expends any effort in any attempt to enforce payment of all or any part or installment of any sum due the holder hereunder, or if this note is placed in the hands of an attorney for collection, or if it is collected through any legal proceedings, Maker agrees to pay all collection costs and fees incurred by the holder, including reasonable attorneys' fees.
