    Tyson Foods, Inc. Announces Final Results of Tender Offer for IBP, inc.

SPRINGDALE, Ark., Aug. 9 -- Tyson Foods, Inc. (NYSE: TSN)
                                                     ---
today announced the final results of the successful completion of its tender
offer, made through its wholly-owned subsidiary Lasso Acquisition Corporation,
to purchase up to 50.1% of the outstanding shares of IBP, inc. (NYSE: IBP)
                                                                      ---
for $30.00 per share. The cash tender offer, which was oversubscribed, expired
at 12:00 midnight, New York City time, on Friday, August 3, 2001.

      91,284,205 shares of IBP common stock, representing approximately 84.4% of
the total outstanding shares, had been tendered and not withdrawn by the
expiration date. Pursuant to the terms of the offer, Tyson will purchase
53,612,799 of the tendered shares. The final results of proration indicate that
Tyson will purchase approximately 58.7% of the IBP shares tendered by each IBP
shareholder. The IBP shares which were tendered, but are not purchased, will be
returned to the stockholders promptly.

     The depositary for the tender offer, Wilmington Trust Company, will be
issuing payment promptly for the IBP shares accepted under the tender offer.
After the purchase of the IBP shares, Tyson and Lasso Acquisition Corporation
will own approximately 50.1% of the outstanding shares of IBP.

     As previously announced, the tender offer will be followed by the merger of
IBP with and into Lasso Acquisition Corporation. As a result of the merger, the
IBP business will continue as a wholly owned subsidiary of Tyson. In the merger,
each IBP share (other than shares owned by Tyson or any of its subsidiaries or
by IBP as treasury stock, all of which will be canceled) will be converted into
$30.00 of Tyson Class A common stock if, during the 15 consecutive trading days
ending on the fifth trading day preceding the effective time of the merger, the
average closing price per share of Tyson Class A common stock is between $12.60
and $15.40. If the average price is above $15.40, each IBP share will be
converted into 1.948 Tyson Class A common shares. If the average price is below
$12.60, each IBP share will be converted into 2.381 shares of Tyson Class A
common stock. The merger is subject to the satisfaction of certain conditions,
including the approval of IBP stockholders. After purchasing the IBP shares in
the offer, Tyson will have enough IBP shares to approve the merger without any
other stockholder's approval. Tyson and IBP expect to file their joint proxy
statement/prospectus for the merger with the Securities and Exchange Commission
this week.
