Tyson Completes Cash Tender for IBP

SPRINGDALE, Ark., Aug. 4 /PRNewswire/ -- Tyson Foods, Inc. (NYSE: TSN - news) today announced the preliminary 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 - news) 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.

Based on preliminary information, 106,994,197 shares of IBP common stock, representing approximately 99.1% of the total outstanding shares, had been tendered and not withdrawn by the expiration date, including approximately 15,712,662 shares tendered by guaranteed delivery. Pursuant to the terms of the offer, Tyson will purchase approximately 53,499,688 of the tendered shares. The preliminary results of proration indicate that Tyson will purchase 50.0% of the IBP shares tendered by each IBP shareholder. Tyson will announce the final proration percentage after the close of business on Wednesday, August 8, 2001, which is the day when the period for delivering IBP shares tendered by guaranteed delivery expires.

The determination of the proration factor is subject to final confirmation of the proper delivery of all shares tendered and not withdrawn, including shares tendered pursuant to the guaranteed delivery procedure, and the total number of IBP shares outstanding as of the close of business on Friday, August 3, 2001. Payment for shares accepted for payment, and return of all other shares tendered, will occur promptly after completion of the final proration computation.

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 shareholders. After purchasing the IBP shares in the offer, Tyson will have enough IBP shares to approve the merger without any other shareholder's approval. Tyson and IBP expect to file their joint proxy statement/prospectus for the merger with the Securities and Exchange Commission within the next week to ten days.

Tyson previously announced that the Delaware Chancery Court approved a settlement agreement to resolve an existing shareholder suit against IBP, which paved the way for the closing of the cash tender.

John Tyson, chairman, president and CEO, said, "A lot of hard work has been done over the past few months to put these two great companies in a position where we could combine them together. I'm happy that we're finally getting a chance to move forward and create the world's leading protein provider. As we told you earlier, we hope to complete the stock portion of this transaction within the next 60 days."
