               also  execute,  New  Swift  shall  expressly  assume  all  of the
               Company's  obligations  under this Agreement and the Rights,  and
               the Rights Agent shall consent and agree to such  assignment  and
               assumption,  that New Swift  shall be  entitled to enforce all of
               the rights and interests of the Company under this  Agreement and
               the Rights,  and to the release of the Company from its covenants
               and obligations with respect to this Agreement and the Rights."

               3. Addition of New Section 35.

     The Rights  Agreement is amended by adding a new Section 35, which reads as
follows:

               "Section 35.  Exception For Plan of Merger.  Notwithstanding  any
               provision  of  this   Agreement  to  the   contrary,   neither  a
               Distribution Date nor a Stock Acquisition Date shall be deemed to
               have  occurred,  none of New  Swift or any of its  Affiliates  or
               Associates  shall be deemed to have become an  Acquiring  Person,
               and no holder of any Rights  shall be entitled  to  exercise  any
               Rights under, or be entitled to any rights under, any of Sections
               3, 7, 11 or 13 of this  Agreement,  in any such case by reason of
               (a) the  approval,  execution,  delivery or filing of the Plan of
               Merger or any amendments thereof approved in advance by the Board
               of Directors of the Company or (b) the  commencement or, prior to
               termination of the Plan of Merger, the consummation of any of the
               transactions  contemplated  by the Plan of Merger  in  accordance
               with their terms, including the Merger (as defined in the Plan of
               Merger)."

               4. Effectiveness.

     This  Amendment  shall be deemed  effective  as of December  12, 2005 as if
executed by both  parties  hereto on such date.  Except as amended  hereby,  the
Rights  Agreement  shall  remain in full force and effect and shall be otherwise
unaffected hereby.

               5. Miscellaneous.

     This Amendment  shall be deemed to be a contract made under the laws of the
State of Texas  and for all  purposes  shall be  governed  by and  construed  in
accordance  with the laws of such state  applicable  to contracts to be made and
performed  entirely  within such state.  This  Amendment  may be executed in any
number of  counterparts,  each of such  counterparts  shall for all  purposes be
deemed to be an original,  and all such counterparts  shall together  constitute
but one and the same instrument. If any term, provision, covenant or restriction
of this  Amendment  is  held  by a court  of  competent  jurisdiction  or  other
authority to be invalid, illegal, or unenforceable,  the remainder of the terms,
provisions,  covenants and  restrictions  of this Amendment shall remain in full
force and effect and shall in no way be affected, impaired or invalidated.

     This Agreement may be executed in multiple  counterparts with the effect of
one  original,  and facsimile  signatures  will have the same effect as original
signatures.
