WELLS FARGO BANK TERM NOTE $10,000,000.00 Phoenix, Arizona October 1, 1993 FOR VALUE RECEIVED, the undersigned KNIGHT TRANSPORTATION, INC. ("Borrower") promises to pay to the order of WELLS FARGO BANK, NATIONAL ASSOCIATION ("Bank") at its office at Arizona RCBO #03839, 100 West Washington, Phoenix, AZ 85003, or at such other place as the holder hereof may designate in lawful money of the United States of America and n immediately available funds, the principal sum of $10,000,000,00, with interest thereon as set forth herein. INTEREST/FEES: (a) INTEREST. The outstanding principal balance of this Note shall bear interest at the rate of 5.75000% per annum (computed on the basis of a 360-day year, actual days elapsed). (b) DEFAULT INTEREST. From and after the maturity date of this Note, or such earlier date as all principal owing hereunder becomes due and payable by acceleration or otherwise, the outstanding principal balance of this Note shall bear interest until paid in full at an increased rate per annum (computed on the basis of a 360-day year, actual days elapsed) equal to 4% above the rate of interest from time to time applicable to this Note. (c) COLLECTION OF PAYMENTS. Borrower authorizes Bank to collect all principal and interest due hereunder by charging Borrower's demand deposit account number 4159-518950 with Bank, or any other demand deposit account maintained by any Borrower with Bank, for the full amount thereof. Should there be insufficient funds in any such demand deposit account to pay all such sums when due, the full amount of such deficiency shall be immediately due and payable by Borrower. REPAYMENT AND PREPAYMENT: (a) REPAYMENT. Principal and interest shall be payable on the 1ST day of each MONTH in installments or $192,558.23 each, commencing NOVEMBER 1, 1998, and continuing up to and including SEPTEMBER 1, 2003, with a final installment consisting of all remaining unpaid principal and accrued interest due and payable in full on OCTOBER 1, 2003. (b) PREPAYMENT. Borrower may prepay principal on this Note at any time in the minimum amount of $100,000.00; provided however, that if the outstanding principal balance of this Note is less than said amount, the minimum prepayment amount shall be the entire outstanding principal balance hereof. In consideration of Bank providing this prepayment option to Borrower, or if this Note shall become due and payable at any time prior to the maturity date hereof by acceleration or otherwise, Borrower shall pay to Bank immediately upon demand a fee which is the sum or the discounted monthly differences for each month from the month of prepayment through the month in which this Note matures, calculated as follows for each such month: (i) DETERMINE the amount of interest which would have accrued each month on the amount prepaid at the interest rate applicable to such amount had it remained outstanding until the scheduled maturity date hereof. (ii) SUBTRACT from the amount determined in (i) above the amount of interest which would have accrued for the same month on the amount prepaid for the remaining term of this Note at the Money Market Funds Rate in effect on the date of prepayment for new loans made for such term and in a principal amount equal to the amount prepaid. (iii) If the result obtained in (ii) for any month is greater than zero, discount that difference by the Money Market Funds Rate used in (ii) above. Each Borrower acknowledges that prepayment of such amount may result in Bank incurring additional costs, expenses and/or liabilities, and that it is difficult to ascertain the full extent of such costs, expenses and/or liabilities. Each Borrower, therefore, agrees to pay the above-described prepayment fee and agrees that said amount represents a reasonable estimate of the prepayment costs, expenses and/or liabilities of Bank. If Borrower fails to pay any prepayment fee when due, the amount of such prepayment fee shall thereafter bear interest until paid at a rate per annum 2.000% above the Prime Rate in effect from time to time (computed on the basis of a 360-day year, actual days elapsed). The "Prime Rate" is a base rate that Bank from time to time establishes and which serves as the basis upon which effective rates of interest are calculated for those loans making reference thereto. Each change in the rate of interest on any such past due prepayment fee shall become effective on the date each Prime Rate change is announced within Bank. 1 The "Money Market Funds Rate" means the rate per annum which Bank estimates and quotes to its borrowers as the rate, adjusted for reserve requirements, federal deposit insurance and any other amount which Bank deems appropriate, at which funds in the amount of a loan and for a period of time comparable to the term of such loan are available for purchase in the money market on the date such loan is made with the understanding that the Money Market Funds Rate is Bank's estimate only and that Bank is under no obligation to actually purchase and/or match funds for any transaction. This rate is not fixed by or related in any way to any rate that Bank quotes or pays for deposits accepted through its branch system. All prepayments of principal shall be applied on the most remote principal installment or installments then unpaid. EVENTS OF DEFAULT: Any default in the payment or performance of any obligation under this Note, or any defined event of default under any loan agreement now or at any time hereafter in effect between Borrower and Bank (whether executed prior to, concurrently with or at any time after this Note), shall constitute an "Event of Default" under this Note. MISCELLANEOUS: (a) REMEDIES. Upon the occurrence of any Event of Default, the holder of this Note, at the holder's option, may declare all sums of principal, interest, fees and charges outstanding hereunder to be immediately due and payable without presentment, demand, notice of nonperformance, notice of protest, protest or notice of dishonor, all of which are expressly waived by each Borrower, and the obligation, if any, of the holder to extend any further credit hereunder shall immediately cease and terminate. Each Borrower shall pay to the holder immediately upon demand the full amount of all payments, advances, charges, costs and expenses, including reasonable attorneys' fees (to include outside counsel fees and all allocated costs of the holder's in-house counsel), expended or incurred by the holder in connection with the enforcement of the holder's rights and/or the collection of any amounts which become due to the holder under this Note, and the prosecution or defense of any action in any way related to this Note, including without limitation, any action for declaratory relief, whether incurred at the trial or appellate level, in an arbitration proceeding or otherwise, and including any of the foregoing incurred in connection with any bankruptcy proceeding (including without limitation, any adversary proceeding, contested matter or motion brought by Bank or any other person) relating to any Borrower or any other person or entity. (b) OBLIGATIONS JOINT AND SEVERAL. Should more than one person or entity sign this Note as a Borrower, the obligations of each such Borrower shall be joint and several. (c) GOVERNING LAW. This Note shall be governed by and construed in accordance with the laws of the state of Arizona. IN WITNESS WHEREOF, the undersigned has executed this Note as of the date first written above.
