Transaction Valuation*                                      Amount of Filing Fee

$32,253,966................................................        $6,451

- -------
  * Estimated for purposes of calculating the amount of the filing fee only.
    The filing fee calculation assumes the purchase of all outstanding shares
    of common stock, par value $1.00 per share, of KLLM Transport Services,
    Inc. (the "Common Stock"), a Delaware corporation (the "Company"),
    including the related preferred stock purchase rights (the "Rights" and,
    together with the Common Stock, the "Shares") at a per Share price of
    $7.75 in cash, without interest. Based on the Company's Annual Report on
    Form 10-K for its fiscal year ended December 31, 1999 there were (i)
    4,101,468 Shares issued and outstanding (as of March 24, 2000), (including
    the 539,600 Shares owned by the Filing Persons); (ii) 9,334 Shares
    subscribed for by the Company's employees under the Company's employee
    stock option plan, and (iii) 51,000 Shares issuable under the Company's
    incentive stock option plan which are currently exercisable. Based on the
    foregoing, the transaction value is equal to the product of 4,161,802
    Shares and $7.75 per Share. The amount of the filing fee calculated in
    accordance with Rule 0-11 of the Securities Exchange Act of 1934, as
    amended, equals 1/50th of one percent of the value of the transaction.
[_]Check the box if any part of the fee is offset as provided by Rule 0-
   11(a)(2) and identify the filing with which the offsetting fee was
   previously paid. Identify the previous filing by registration statement
