                                            Subject Company: M.S. Carriers, Inc.
                                                     Commission File No. 0-14781

                                                            Date: March 13, 2000


     Certain information in this filing consists of forward-looking statements
within the meaning of the Private Securities Litigation Reform Act of 1995. Such
statements include, but are not limited to, statements concerning Swift's future
growth, Swift's projected revenues in 2003, Swift's ability to recruit and train
qualified drivers, Swift's low operational costs, the benefits of Swift's
terminal network, including fuel cost savings, Swift's use of guaranteed return
agreements to lessen the impact of the declining used truck market, Swift's use
of surcharges to lessen the impact of fuel price increases, the anticipated
closing of the acquisition of M.S. Carriers in the second quarter of 2001, the
integration of Swift and M.S. Carriers by January 2002, revenue synergies from
cross-selling and growth in international business expected to result from the
acquisition of M.S. Carriers, Swift's ability to address low freight demand by
increasing business volume with existing customers and cross-selling to
customers of M.S. Carriers, the acceleration of cost synergies associated with
the acquisition of M.S. Carriers to 2002, savings in health and liability
insurance expenses expected to result from the acquisition of M.S. Carriers, and
future opportunities for well-capitalized trucking companies, including the
elimination of competitors, the elimination of excess capacity, and increased
driver availability.

     Such forward-looking statements are based upon the current beliefs and
expectations of Swift's management and are subject to significant risks and
uncertainties. Actual results may differ from those set forth in the
forward-looking statements. As to Swift's business and financial performance
generally, the following factors, among others, could cause actual results to
differ materially from those in forward-looking statements: excess capacity in
the trucking industry; significant increases or rapid fluctuations in fuel
prices, interest rates, fuel taxes, tolls, license and registration fees,
insurance premiums, and driver compensation, to the extent not offset by
increases in freight rates or fuel surcharges; an unanticipated number of claims
for which Swift is self-insured; difficulty in attracting and retaining
qualified drivers and owner operators, especially in light of the current
shortage of qualified drivers and owner operators; recessionary economic cycles
and downturns in customers' business cycles, particularly in market segments and
industries (such as retail and manufacturing) in which Swift has a significant
concentration of customers; a significant reduction in or termination of the
Company's trucking services by a key customer; seasonal factors such as harsh
weather conditions that increase operating costs; the inability of Swift to
continue to secure acceptable financing arrangements; and the ability of Swift
to continue to identify and combine acquisition candidates that will result in
successful combinations. With respect to the proposed acquisition of M.S.
Carriers, these risks and uncertainties include, but are not limited to, the
following: the ability to obtain governmental approvals of the merger on the
proposed terms and schedule; the failure of Swift's and M.S. Carriers'
stockholders to approve the merger; the risk that the businesses will not be
integrated successfully; the risk that the revenue and other synergies and cost
savings from the merger may not be fully realized or may take longer to realize
than expected; fluctuating stock market levels that could cause Swift's stock
value to be less than the current Swift or M.S. Carriers stock value; the
difficulty the stock market may have in valuing the business model of the
combined company; and disruption from the merger making it more difficult to
maintain relationships with customers, employees, or suppliers.

     A discussion of these and other factors that could cause Swift's and M.S.
Carriers results to differ materially from those described in the
forward-looking statements can be found in the most recent Annual Reports on
Forms 10-K of Swift and M.S. Carriers, filed with the Securities and Exchange
Commission and available at the Securities and Exchange Commission's internet
site (http://www.sec.gov).

     The proposed merger transaction between Swift and M.S. Carriers will be
submitted to the companies' stockholders for their consideration. Swift will
file a registration statement on Form S-4 that will include a joint proxy
statement/prospectus. Stockholders should read the joint proxy
statement/prospectus regarding the proposed transaction that will be filed with
the SEC and mailed to stockholders. The joint proxy statement/prospectus will
contain important information that stockholders should consider. Stockholders
will be able to obtain a free copy of the joint proxy statement/prospectus, as
well as other filings containing information about Swift and M.S. Carriers,
without charge, at the SEC's internet site (http://www.sec.gov). Copies of the
joint proxy statement/prospectus and the SEC filings that will be incorporated
by reference in the joint proxy statement/prospectus can also be obtained,
without charge, by directing a request to: Swift Transportation Co., Inc., 2200
South 75th Avenue, Phoenix, AZ 85043, Attention: Chief Financial Officer

M.S. Carriers' common stock, except that Jerry Moyes, CEO of Swift beneficially

Carriers. Certain employees of M.S. Carriers, including participants, may
receive accelerated vesting of their stock options in connection with the merger
in accordance with their existing stock option agreements. In addition, certain
officers of M.S. Carriers, as a condition to the closing of the merger, will
enter into employment agreements that will become effective upon completion of
the merger. A description of the employment agreements will be contained in the
joint proxy statement/prospectus.
