Item 1.01  Entry into a Material Definitive Agreement.
------------------------------------------------------
On  November  17,  2005,  the  Company's  Board of Directors, in accordance with
the  recommendation of its Compensation and Stock Option Committee, approved the
extension  of  the Company's Incentive Compensation Plan 2000C to apply to 2005.
The participants in the Plan are Robert W. Weaver, President and Chief Executive
Officer  of  the  Company,  W.  Clif  Lawson, Executive Vice President and Chief
Operating  Officer  of  the  Company,  Larry J. Goddard, Vice President-Finance,
Chief  Financial  Officer,  Secretary  and Treasurer of the Company, and several
other  members  of  senior  management  who  are  not  executive officers of the
Company.

For  2005,  the  Plan provides for cash incentive compensation to be paid to the
participants  based  on  the Company's operating ratio and operating revenue for
2005.  Incentive compensation payable under the Plan could range from nothing to
approximately 120% of a participant's annual base compensation for 2005. Subject
to  the  terms of the Plan, any amounts payable under the Plan for 2005 would be
paid in three annual installments. The first annual installment would be for 50%
of  the  amount  payable, and would be paid by March 31, 2006. The remaining two
installments  each  would be for 25% of the amount payable; one would be paid by
March 31, 2007 and the other by March 31, 2008.

The  Plan was originally adopted to provide incentive compensation for the years
2000 through 2002, and was previously amended to also apply to 2003 and 2004.  A
copy  of  the  Plan  as  extended  through 2004 was filed as Exhibit 10.3 of the
Company's  Quarterly  Report  to  the Securities and Exchange Commission for the
quarter  ended  September  30, 2004.  The Plan as extended for 2005 continues to
apply  the  same  formula for calculating incentive compensation as was used for
2004.  Based on the Company's performance to date for 2005, the Company does not
expect  that  payments  to  participants  under the Plan will constitute a large
percentage of their compensation for 2005.
