In comparing the financial results of the three months ended December 31, 2004 to the three months ended December 31, 2003, Robert M. Powell, Chairman and CEO of the Company, made the following statement:

Solid freight demand throughout the quarter helped us post strong revenue growth of 14.8% on just 7.4% growth in our tractor fleet. The revenue growth beyond fleet growth was due to higher revenue per mile (+4.1%) and increased average miles per tractor per week (+2.6%).

We also made progress on our cost management initiatives. In particular, we substantially completed our seven-quarter plan to reduce the average ages of our tractor and trailer fleets, which was the primary reason for the 24.3% reduction in operations and maintenance expenses. Lower diesel fuel prices and our internal efforts to improve the efficiency of our fuel surcharge revenue program also aided in expanding our margins. That margin expansion was hindered by higher insurance and claims costs, which were up 60.1% due to our continued efforts to settle and litigate certain older claims. We are encouraged, however, by the progress that we’ve made in both accident prevention and claims management. Our accident frequency was down 14.6%, our volume of open liability claims was down 28.6% and our volume of liability claims in litigation was down 27.0%. Overall, the operating ratio of 92.9% improved 2.7 percentage points and represents our best operating margin since the fourth quarter of 1999.

The results of our efforts to improve revenues and reduce expenses is evident on the bottom line where we posted our highest net income ($3.0 million) and diluted earnings per share ($0.32) since our initial public offering in 1992. Over the past several years, we have meticulously benchmarked our current operating statistics against those of 1998, which is the year that produced the strongest operating statistics in our public history. Our focus on improving revenue per mile and equipment utilization while controlling key expense items enabled us to improve our performance against those benchmarks.

                     During 2005, we will continue to work toward our benchmarks.

This press release contains forward-looking statements and information that are based on our current beliefs and expectations and assumptions we have made based upon information currently available. Forward-looking statements include statements relating to our plans, strategies, objectives, expectations, intentions and adequacy of resources, and may be identified by words such as “will,” “could,” “should,” “may,” “believe,” “expect,” “intend,” “plan,” “schedule,” “estimate,” “project” and similar expressions. These statements are based on current expectations and are subject to uncertainty and change. Although we believe that the expectations reflected in such forward-looking statements are reasonable, we cannot assure you that such expectations will be realized. If one or more of the risks or uncertainties underlying such expectations materialize, or if underlying assumptions prove incorrect, actual results may vary materially from those expected. Among the key factors that are not within our control and that have a direct bearing on operating results are increases in fuel prices, adverse weather conditions, increased regulatory burdens and the impact of increased rate competition. Our results have also been, and will continue to be, significantly affected by fluctuations in general economic conditions, as our tractor utilization is directly related to business levels of shippers in a variety of industries. In addition, shortages of qualified drivers and intense or increased competition for drivers have adversely impacted our operating results and our ability to grow and will continue to do so. Results for any specific period could also be affected by various unforeseen events, such as unusual levels of equipment failure or vehicle accident claims. Additional risks associated with our operations are discussed in our SEC filings, including our annual report on Form 10-K and our quarterly reports on Form 10-Q.

All forward-looking statements attributable to us, or persons acting on our behalf, are expressly qualified in their entirety by this cautionary statement.

We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise. In light of these risks and uncertainties, the forward-looking events and circumstances discussed in this press release might not occur.
