                             1993 INCENTIVE PLAN
                     GROUND RULES FOR MSC INCENTIVE PLAN
                         FOR DESIGNATED KEY EMPLOYEES
                                  March 1, 1993

I.     General Introduction
       --------------------

       A.  The 1993 Incentive Plan is designed to be consistent
               -------------------
           with the M.S. Carriers Incentive Philosophy, (Appendix A)
           and will be improved periodically as the needs of the 
           company change.

       B.  The incentive plan is desinged to (1) promote team-
           work in all areas of the company, (2) get people to 
           look at the "big picture", and (3) focus those managers
           and key employees able to affect the bottom line on 
           actual profitability results for the purpose of 
           improving shareholder value.  The quarterly OR 
           will establish the amount of incentive a participant can
           receive.  The objective is to tie the management group
           together as a team which will result in higher net
           income to the company.  Participants will focus on
           activities which affect profitability (things
           that matter) rather than just activities (things that
           keep us busy but have little botton line value.)

C.     Eligibility:  All executive, middle management department heads
       -----------
       and other key employees approved by executive management 
       incentive bounus plan.

II.    Description of Incentive Plan
       -----------------------------

       A.  Participation Criteria: To participate, an employee must:
           ----------------------

           1.  Be assigned to a position selected by executive management.

           2.  Be designated a member of the plan for the full quarter.

           3.  If you are absent for an extended period of time, such as
               a leave of absence or protracted illness, your bonus will
               be prorated, provided you work sometime during the quarter.  
               You will receive a percent of the bonus equal to the number
               of work days you were present during the quarter, divided
               by the total work days in the quarter


           4.  If you reach age 65 and retire before the quarter is 
               completed, you will receive a bonus computed as in 3 above.

       B.  Mangers will be expected to hold monthly meetings with incentive
           participants to discuss profitablity opportunities and to analyze
           the quarterly results to identify ways improvements can be made.

       C.  The incentive plan system will be evaluated by executive
           management each year so that improvements can be made to meet
           the needs of the company through time.

                 M.S. CARRIERS' INCENTIVE PHILOSOPHY
                 -----------------------------------

       .  We will not allow external business or economic factors to
          influence positively or negatively the company's incentive
          plan.  The incentive plan will be reviewed annually to reflect
          realistic changing business conditions.

       .  We will emphasize to participants that payments earned from
          the incentive plan will vary and should not become a factor
          in establishing an individual's or family's standard of living.

       .  We will pay incentives to participants to reflect the groups'
          impact on operating ratio so that everyone's efforts will be
          focused toward failure cost elimination and continous improvement
          in customer and employee satisfaction.
