Item 6.   Contracts, Arrangements, Understandings or
          Relationships With Respect to Securities of the Issuer

     On July 9, 1998, the Issuer, Zapata and Messrs. Malcolm Glazer and Avram
Glazer (the "Glazers") entered into a letter agreement ("July 9th Agreement")
pursuant to which the Issuer's Board of Directors agreed to use all reasonable
efforts to cause the Glazers to be elected to the Issuer's Board of Directors at
the Issuer's 1998 Annual Meeting which is scheduled for August 27, 1998. In
addition, the Issuer agreed in the July 9th Agreement to immediately expand the
size of its entire Board of Directors from five to six directors so that the
Glazers, upon their election, would constitute two out of the Issuer's six
directors. In consideration for the Issuer's undertakings, Zapata and the
Glazers agreed in the July 9th Agreement, until the earlier of one year
from the date thereof or the date on which Zapata owns more than 50% of the
Issuer's outstanding shares of Common Stock, to (a) cause all Issuer shares
beneficially owned by them to be voted for the director candidates nominated by
the Issuer's Board, (b) refrain from assisting another person in their efforts
to be elected to the Issuer's Board and (c) refrain from any action to change
the membership of the Issuer's Board.

     On July 9, 1998, the Issuer announced that it had increased the size of its
Board of Directors from five directors to six directors.

     A copy of the July 9th Agreement is annexed hereto as Exhibit 1 and is
incorporated herein by reference. The above description is qualified in its
entirety by reference to such letter agreement.

Board of Directors
Envirodyne Industries, Inc.
701 Harger Road, Suite 190
Oak Brook, Illinois  60523

Gentlemen:

     You have agreed to nominate, and to use all reasonable efforts to elect,
Messrs. Malcolm I. Glazer and Avram A. Glazer (the "Glazers") to the Envirodyne
Industries, Inc. ("Envirodyne") Board of Directors at Envirodyne's 1998 Annual
Meeting, which is scheduled for August 27, 1998. You have also agreed to
increase the size of the entire Board to six directors so that, upon their
election, the Glazers will constitute two out of Envirodyne's six directors.

     In the event that either of the Glazers are unable or unwilling to serve on
the Board at any time while the Restricted Activities (defined below) are in
effect, then, upon their resignation or departure from the Board and so long as
Zapata continues to hold at least 20% of Envirodyne common stock, you have
agreed to promptly take all actions necessary to elect to the Board a successor
designated by Zapata Corporation ("Zapata") and reasonably acceptable to the
Board.

     In consideration of the foregoing, until the earlier of one (1) year from
the date hereof or the date on which Zapata owns (of record or beneficially)
more than 50% of the then outstanding shares of common stock of Envirodyne,
Zapata and the Glazers each agree (a) to cause all shares of Envirodyne common
stock beneficially owned by it or him to be voted for the director candidates
nominated by the Board (assuming such candidates include the Glazers), (b) not
to take any action to assist any other individuals attempting to be elected
directors of Envirodyne and (c) not to take any action to change the membership
of the Board (collectively, the "Restricted Activities").
