                  TYSON TO TERMINATE CASH TENDER FOR IBP;
                    START WORK ON CASH ELECTION MERGER


Springdale, Arkansas - February 28, 2001 - Tyson Foods, Inc. (NYSE: TSN)
said today it expects to terminate its cash tender offer to purchase for
cash up to 50.1% of the outstanding shares of common stock of IBP, inc.
(NYSE: IBP), and to begin work on a cash election merger, consistent with
the IBP agreement.  The tender offer expires at midnight, New York City
time, tonight. Any shares tendered will be returned.

John Tyson, chairman, president and chief executive officer, said,
"Unfortunately, it will be impossible to complete the cash tender offer by
the 28th.  IBP continues to work with the SEC to resolve their accounting
issues.  After that work is complete, we will determine what effect these
matters will have on our deal."

Pursuing a cash merger will delay the proposed transaction.  It
necessitates filing a prospectus and proxy statement with the SEC, which
would include IBP's restated financials, and requires a special shareholder
meeting and vote of IBP and Tyson shareholders.
