AMENDMENT NO. 3 TO TENDER OFFER STATEMENT

         This Amendment No. 3 to the Tender Offer Statement on Schedule TO (as
amended hereby, the "Schedule TO") relates to the offer by Lasso Acquisition
Corporation, a Delaware corporation ("Purchaser") and a wholly-owned subsidiary
of Tyson to purchase up to the number of Shares, which, together with the Shares
owned by Tyson, constitutes 50.1% of the outstanding Shares at $30.00 per Share,
net to the seller in cash, upon the terms and subject to the conditions set
forth in the Offer to Purchase, dated July 3, 2001 (as amended, the "Offer to
Purchase"), and in the related Letter of Transmittal (which, together with the
Offer to Purchase and any amendments or supplements thereto, collectively
constitute the "Offer"). Capitalized terms used herein and not otherwise defined
shall have the meanings ascribed to them in the Offer to Purchase. The item
numbers and responses thereto below are in accordance with the requirements of
Schedule TO.

         The Offer, proration period and withdrawal rights will expire at 12:00
Midnight, New York city time, on Friday, August 3, 2001, unless the Offer is
extended.

         Except as amended below, the information set forth in the Offer to
Purchase and the related Letter of Transmittal is incorporated herein by
reference with respect to Items 1 through 11 of this Schedule TO.




Item 7.  Source and Amount of Funds or Other Consideration

         Section 11 of the Offer to Purchase is hereby amended and restated in
its entirety as follows:

         "11. Source and Amount of Funds. We will need approximately $1.7
billion to purchase the number of Shares representing, together with Shares
owned by Tyson, 50.1% of the outstanding Shares pursuant to the Offer and to pay
related fees and expenses. In addition, we will need approximately $1.1 billion
to repay certain indebtedness of the Company. We intend to obtain such funds
from the following credit facilities, which will support aggregate borrowings of
up to $2.85 billion.

     o    On July 27, 2001 we entered into a commitment letter with The JPMorgan
          Chase Manhattan Bank ("Chase"), J.P. Morgan Securities Inc.
          ("JPMorgan"), Merrill Lynch Capital Corporation ("MLCC"), SunTrust
          Bank ("SunTrust") and SunTrust Capital Markets, Inc. with respect to a
          senior unsecured bridge credit facility in an aggregate principal
          amount of $2.5 billion (the "Bridge Facility"). The commitments will
          expire and outstanding loans under the Bridge Facility will mature on
          the date that is 180 days after the date of execution of definitive
          documentation for the Bridge Facility. In addition to certain fees, we
          will pay interest on borrowings under the Bridge Facility which will
          vary based on the type of borrowing. The initial interest rate for
          borrowings of Eurodollar loans under the Bridge Facility will be equal
          to an adjusted LIBOR rate plus 1.10% per annum. The initial interest
          rate for borrowings of base rate loans under the Bridge Facility will
          be at an "Alternate Base Rate" (which is the higher of Chase's prime
          rate or the federal funds effective rate plus 0.5%) plus 0.10%. The
          interest rate on the Bridge Facility is subject to further adjustment
          if the facility remains outstanding for more than 120 days or our
          credit ratings change. The effectiveness of the Bridge Facility is
          conditioned on the completion of the Offer, completion of definitive
          documentation, effectiveness of the Receivables Facility Bridge
          Facility (as defined below) and other customary conditions.

     o    On July 27, 2001 we entered into a commitment letter with Chase and
          JPMorgan with respect to a senior unsecured receivables bridge credit
          facility in an aggregate principal amount of $350 million (the
          "Receivables Bridge Facility"). The commitment will expire and
          outstanding loans will mature under the Receivables Bridge Facility on
          the date that is 90 days after the date of execution of definitive
          documentation for the Receivables Bridge Facility. In addition to
          certain fees, we will pay interest on borrowings at the rates
          described above for the Bridge Facility. The effectiveness of the
          Receivables Bridge Facility is conditioned on the completion of the
          Offer, completion of definitive documentation, effectiveness of the
          Bridge Facility and other customary conditions.

If we are unable to consummate the foregoing financing arrangements, we will
seek alternative financing arrangements. Following the closing of the
transactions, Tyson will seek to refinance the Bridge Facility through the
issuance of up to $2.5 billion of senior unsecured notes of the Company and will
seek to refinance the Receivables Bridge Facility with an approximately $750
million asset backed receivables facility. However, the decision whether or not
to affect any refinancing and the timing and nature of such refinancing will
depend on a number of factors, including, market conditions, interest rates and
interest rate spreads and the availability of alternative financing.

     In addition, on July 27, 2001 we entered into a commitment letter with
Chase, JPMorgan, MLCC, Merrill Lynch Bank USA and SunTrust with respect to a
364-day senior unsecured credit facility in an aggregate principal amount of
$500 million (the "364-Day Facility") and a five-year senior unsecured credit
facility in an aggregate principal amount of $500 million (the "Five-Year
Facility"). The proceeds from the 364-Day Facility and the Five-Year Facility
will be used to refinance our outstanding senior credit facility in the



aggregate principal amount of $1 billion, for working capital and, if necessary,
to complete the Merger, including the payment of certain fees and expenses
incurred in connection with the Offer and the Merger. The 364-Day Facility will
expire and the borrowings thereunder will mature on the date that is 364 days
after the date of the execution of definitive documentation for the facility.
The Five-Year Facility will expire and the borrowings thereunder will mature on
the fifth anniversary of the execution of definitive documentation for the
facility. In addition to certain fees, we will pay interest on borrowings under
the 364-Day Facility and the Five-Year Facility which will vary based on the
type of borrowing. The interest rate for Eurodollar loans will be equal to an
adjusted LIBOR rate plus a spread to be determined based upon our credit
ratings, which spread initially will be 0.850% per annum for the 364-Day
Facility and 0.825% per annum for the Five-Year Facility. The interest rate for
base rate loans will be the Alternate Base Rate plus a spread to be determined
based on our credit ratings."

         The commitment letters with respect to the Bridge Facility and the
Receivables Bridge Facility are filed as Exhibits (b)(1) and (b)(2),
respectively, to this Schedule TO and incorporated herein by reference.
