SUCCESSOR EMPLOYER AGREEMENT

         THIS  AGREEMENT is made and entered  into this 13th day of March,  1999
(the  "Agreement"),  between KNIGHT  ACQUISITION  CORP., an Arizona  corporation
("KAC"),  and ACTION DELIVERY  SERVICE,  INC., a Texas  corporation,  and Action
Warehouse  Services,  Inc., a Texas Corporation  (individually and collectively,
"Action").

                                    RECITALS.

         A. KAC is in the truck load transportation business.

         B. Action is also in the truck load transportation business.

         C. Contemporaneous  with  this  Agreement,  KAC is  entering  into  an
agreement with Action,  pursuant to which KAC will acquire  substantially all of
Action's assets (the "Acquisition Transaction").

         D. In accordance with Revenue  Procedure  96-60, KAC and Action wish to
enter into an  agreement  pursuant to which KAC,  as  successor  employer,  will
submit all Forms W-2 for the  former  employees  of Action who are  subsequently
employed by KAC to the Internal Revenue Service for and on behalf of Action.

                                   AGREEMENT.

     Now, therefore, it is agreed as follows:

     1. The term  "Transferred  Employees"  means those  employees of Action who
were  terminated  by Action and hired by KAC. KAC hereby agrees to undertake and
provide to Action all  services  previously  provided by Action with  respect to
reporting under FICA, FUTA and Medicare for the Transferred Employees.  From and
after  March 15,  1999,  the  Transferred  Employees  who are hired by KAC shall
become  employees of KAC and KAC shall be responsible for paying the Transferred
Employees. KAC will provide Action with a list of the Transferred Employees.

     2.  Action  and KAC hereby  agree  that  Action  shall be  relieved  of the
obligation to furnish Forms W-2 to any of the  Transferred  Employees upon their
hire by KAC and that KAC, as the successor employer, will issue Forms W-2 at the
end of the 1999 calendar year, as required by law, which shall reflect the wages
paid and taxes withheld by Action, as predecessor  employer,  and by KAC, as the
successor employer.  KAC hereby agrees to assume and perform Action's obligation
to furnish Forms W-2 to all of the  Transferred  Employees for the calendar year


ending December 31, 1999,  including any amounts  reportable by Action as "other
compensation."  Action shall be solely  responsible  for all withholding and the
filing of Forms W-2 and 941 for any  employee  who is not hired by KAC,  and KAC
assumes no  obligations,  liabilities  or duties  with  respect  to such  Action
employees or with respect to the payment of their compensation or payroll taxes.

     3. Action agrees,  in accordance with Revenue  Procedure 96-60, to attach a
statement  to its Form 941  explaining  any  discrepancy  reflected  in Action's
reports on Form W-3 and on Form 941.  Such  statement  shall  include  the name,
address and employer  identification  number of KAC, as the successor  employer,
and a reference to Revenue  Procedure  96-60.  KAC agrees to implement  the same
procedures   and  provide  the  same   information   in  order  to  explain  the
corresponding  differences  on its Form 941.  Action shall comply with all other
terms and conditions of Revenue  Procedure  96-60 and shall file on an expedited
basis any final Form 941.

     4. In  accordance  with Revenue  Procedure  96-60,  all Form W-4s that were
provided  to  Action  by the  Transferred  Employees  shall  be and  are  hereby
transferred  to KAC.  KAC  shall  retain  all  such  Forms  W-4  related  to the
Transferred  Employees on file and shall  deduct and withhold  from the wages it
pays to the Transferred Employees in accordance with the information provided in
those forms, unless a Transferred Employee submits a changed Form W-4. KAC shall
submit to the Internal  Revenue  Service,  in  accordance  with Treas.  Reg. ss.
31.3402(f)(2)-1(g),  copies of all  Forms W-4  received  by  Action  during  the
current and preceding calendar periods.

     5. KAC and Action agree that all Forms W-5 provided to Action by any of the
Transferred  Employees for the current  calendar year are hereby  transferred to
KAC, and KAC hereby agrees to accept and retain such reports.

     6. Action  shall  provide  KAC with any and all  information  necessary  to
implement  this  Agreement  and fulfill the  requirements  of Revenue  Procedure
96-60, including, without limitation, information relating to the wages paid and
taxes  withheld  for each  Transferred  Employee.  Action  shall not destroy any
payroll or employment records it maintains for any of the Transferred  Employees
without KAC's prior written consent.

     7. This Agreement shall be construed so as to assure that KAC, as successor
employer,  and Action, as predecessor employer,  comply with all requirements of
Revenue Procedure 96-60 and Treas. Reg. ss. 31.3402(b)(2)-(g).

     8. KAC shall have no liability or obligation with respect to any actions or
omissions  of  Action  or  any  Transferred  Employee  prior  to  the  time  the
Transferred  Employees  become employees of KAC. Nothing in this Agreement shall
modify the rights or  obligations  of either party as set forth in the documents
implementing  the Acquisition  Transaction,  including,  but not limited to, the
Asset  Purchase  Agreement,  dated as of March 12, 1999,  between and among KAC,
Action and certain  other  parties.  KAC assumes no liability for the payment of

                                       -2-

compensation or payroll taxes for any  Transferred  Employee until such employee
is hired by KAC,  and then  only  with  respect  to  periods  such  person is an
employee of KAC.

     9. This  Agreement is governed by and shall be construed  under the laws of
the State of Arizona and any applicable federal tax law.

     DATED this 13th day of March, 1999.
