corresponding  quarter in 2002. Smithway's net loss was $1.6 million, or ($0.32)
per basic and diluted share,  compared with net loss of $2.0 million, or ($0.42)
per basic and diluted  share,  for the same quarter in 2002.  These results were
consistent with the Company's  previously  announced  expectations.  The Company

This press release and statements made by the Company in its stockholder reports
and   public   filings,   as  well  as  oral   public   statements   by  Company
representatives,   may  contain  certain  forward-looking  information,  usually
identified by words such as "anticipates,"  "believes," "estimates," "projects,"

Such  statements  are based upon the  current  beliefs and  expectations  of the

Actual  results may differ from those set forth in  forward-looking  statements.
The  following  factors,  among  others,  could cause  actual  results to differ
materially  from those in  forward-looking  statements:  failure to turn  around
continued  operating  losses,  which could  result in further  violation of bank
covenants and  acceleration of indebtedness at several  financial  institutions;
the ability to obtain  financing on  acceptable  terms,  and obtain  waivers and
amendments to current financing in the event of default;  economic recessions or
downturns in customers' business cycles;  excessive increases in capacity within
truckload  markets;  surplus  inventories;  decreased demand for  transportation
services offered by the Company;  increases or rapid  fluctuations in inflation,
interest rates,  fuel prices,  and fuel hedging;  the  availability and costs of
attracting and retaining  qualified  drivers and  owner-operators;  increases in
insurance  premiums  and  deductible  amounts,  or changes  in excess  coverage,
relating to accident,  cargo, workers'  compensation,  health, and other claims;
the resale value of used equipment and prices of new equipment; seasonal factors
such as harsh weather  conditions  that  increase  operating  costs;  regulatory
requirements  that  increase  costs  and  decrease  efficiency,   including  new
emissions standards and hours-of-service regulations; changes in


management;   and  the  ability  to   negotiate,   consummate,   and   integrate
acquisitions. Readers should review and consider the various disclosures made by
the Company in this press release,  stockholder  reports, and in its Forms 10-K,
10-Q, and other public  filings.  The Company  disclaims any such  obligation to
