  Kirby Corporation Announces Preliminary Results of Dutch Auction Tender Offer

     HOUSTON,  March 17/PR Newswire/ -- Kirby Corporation  (NYSE: KEX) ("Kirby")
announced today that a preliminary court by BankBoston, N.A., the Depositary for
Kirby's "Dutch Auction" tender offer indicates,  subject to final  verification,
3,068,286 shares of Kirby common stock have been tendered. Pursuant to the terms
of the offer, and based on the preliminary  count, Kirby has elected to increase
the size of the tender offer to accept all shares  tendered at a price of $24.50
per share.

     Kirby  announced  the tender  offer on February 17,  1998,  expressing  its
intentions to purchase up to 3,000,000  shares of its common stock at a purchase
price  ranging  from  $21.00 to $24.50 per share.  The tender  offer  expired on
Monday, March 16, 1998 at 12:00 midnight, New York City time.

     The  determination  of the actual  number of shares to be purchased and the
purchase price are subject to final  confirmation and the proper delivery of all
shares tendered and not withdrawn, including 569,878 shares tendered pursuant to
the guaranteed delivery procedure. Payment for shares tendered and accepted will
be made promptly,  subject to proper  delivery of shares in accordance  with the
terms of the offer.  Funding for the tender offer will be from Kirby's  recently
completed  $38.6 million cash sale of its U.S. flag offshore  product tanker and
harbor service  operations and through  Kirby's  existing bank revolving  credit
agreement.

     The 3,068,286  shares of common stock expected to be repurchased  represent
approximately  12.6% of Kirby's  24,407,436  shares of common stock  outstanding
immediately  prior to the offer.  As of March 17,  1998,  after  purchasing  the
common stock tendered, the Company will have approximately  21,380,000 shares of
common stock outstanding.

1995,  through open market  purchases and the successful  tender offer,  we have
repurchased  approximately 25% of our common stock. Previously,  we purchased in
the open market approximately 4.4 million shares of our common stock for a total
of  approximately  $71.4  million,  at an  average  price of $16.10  per  share.
Currently,  we have  approximately  1.8 million shares  remaining under our 6.25
million Board of Directors' repurchase authorization."
