In comparing the financial results of the quarter ended June 30, 2003 to the
quarter ended June 30, 2002, Robert M. Powell, Chairman and CEO of the Company,
made the following statement:

         Freight volumes have generally improved during the second quarter
         resulting in improved tractor utilization. However, that volume was
         inconsistent among the various geographic regions of the country, which
         caused an up-tick in empty miles in the second quarter as we
         re-positioned equipment between those regions. It is unclear whether
         the improving freight volumes are a product of an overall increase in
         shipper demand or reduced capacity in the truckload industry.
         Regardless of the volume's source, it set the stage for the firming of
         rates, to which our increased revenue per mile attests.

         We continue to see margin improvements through our ongoing campaign to
         address the cost side of our business, most notably in the area of
         wages where several years of effort to reign in driver pay are now
         paying dividends. Fuel prices have also been relatively stable within
         ranges where our fuel surcharge has been sufficient to offset most of
         the additional costs brought about by fuel prices lingering above
         historical averages.

         While margins are improving, there are still a few cost areas we are
         addressing. First, revenue equipment depreciation is up because of the
         extended lives and lower residual values on a large portion of our
         tractor fleet resulting from the recent depression in the used
         equipment markets. We have begun trading those older tractors for new
         ones and are seeing early signs of recovery in those markets as
         evidenced by our improved gains on disposal of property and equipment.
         However, returning the fleet to its historical average age will take
         several quarters during which



         depreciation will remain higher than normal, as will maintenance costs.
         Second, we have seen tightening in the driver markets despite the high
         national unemployment rates. Increased competition for drivers, coupled
         with increased driver turnover due to inconsistent tractor utilization,
         has resulted in an increase in recruiting costs, though our tractor
         fleet was almost fully manned during the second quarter.

         Freight volumes are slowly improving, as are our other fundamental
         operating factors. Overall, we are pleased to have posted our strongest
         earnings per share quarter since the fourth quarter of 1999, but we are
         not yet satisfied and will continue to work on our operating margins.

By agreement with its customers, and consistent with industry practice, the
Company adds a surcharge to its rates as diesel fuel prices increase above an
industry-standard baseline price per gallon. Because fuel prices are volatile,
management believes that presenting operating statistics calculated on the basis
of total revenue, including the fuel surcharge, could provide a distorted
picture of the Company's operating performance, particularly when comparing
results for current and prior periods. Therefore, the fuel surcharge is excluded
from revenue and, instead, taken as a credit against expense when calculating
the operating ratio in the Key Operating Statistics table above. The surcharge
is also excluded from revenue for purposes of calculating revenue per mile in
that table. Revenue data, on both a total basis and excluding the fuel
surcharge, is included in the earnings information table above.

This press release contains forward-looking statements and information that are
based on management's current beliefs and expectations and assumptions made by
it based upon information currently available. Forward-looking statements
include statements relating to the Company's 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 the Company believes that the expectations reflected in such
forward-looking statements are reasonable, it can give no assurance that such
expectations will be realized. Should one or more of the risks or uncertainties
underlying such expectations materialize, or should underlying assumptions prove
incorrect, actual results may vary materially from those expected. Among the key
factors that are not within the Company's control and that have a direct bearing
on operating results are increases in diesel prices, adverse weather conditions
and the impact of increased rate competition. The Company's results have also
been, and will continue to be, significantly affected by fluctuations in general
economic conditions, as the Company's utilization rates are 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 the Company's operating results and its ability to grow, and
will continue to do so. Results for any specific period may also be affected by
various unforeseen events, such as unusual levels of equipment failure or
vehicle accident claims.
