Dear Fellow Stockholder:

Don't Give Zapata Control of Envirodyne By Failing To Vote

     If Zapata and Malcom Glazer are successful in their proxy fight
against your Company they will gain control of Envirodyne.

     Unless you take action by voting the WHITE proxy for the Envirodyne
nominees, Zapata and Mr. Glazer may gain control of Envirodyne. Without
paying you and other stockholders a single cent, let alone a premium for
control, Zapata may gain control of Envirodyne by electing its three
nominees to Envirodyne's five member board.


Vote Your WHITE Proxy Now - Every Vote Is Critical!

     Don't forget - Zapata and the Glazers own over 40% of the outstanding
shares. Unless you vote the WHITE proxy card for the Envirodyne nominees,
Zapata and the Glazers may vote themselves into control of Envirodyne.

     Every single vote is critical in this fight. Every share not voted
could benefit Zapata and the Glazers in their attempt to gain control of
Envirodyne.


Time is Short - Vote Now

     Time before the May 16 Annual Meeting is short, I urge you to sign,
date and return the enclosed WHITE Envirodyne proxy card NOW. If you wish,
you can fax your vote using the instructions on the reverse of this letter.
Your Board of Directors recommends that you vote FOR the five ENVIRODYNE
nominees and AGAINST Zapata's proposal to eliminate the Stockholder Rights
Plan. Do not sign any blue proxy cards sent to you by Zapata. If you
already have signed a blue proxy card, you may revoke that proxy card by
signing, dating and returning the enclosed WHITE proxy card.

                                      Very truly yours,



                                      F. Edward Gustafson
                                      Chairman of the Board, President
                                      and Chief Executive Officer


                                 Important

1.   Regardless of how many shares you own, your vote is very important.
     Please sign, date and mail the enclosed WHITE proxy card. Please vote
     each WHITE proxy card you receive since each account in which you own
     shares must be voted separately. Only your latest dated proxy card
     counts.

2.   We urge you not to return any blue proxy card sent to you by Zapata.

3.   If your shares are held in the name of a bank, broker or other
     nominee, please direct the party responsible for your account to vote
     the WHITE proxy card as recommended by the Board of Directors.


If you have any questions on how to vote your shares, please contact Envirodyne
at (630) 575-2400 or call our proxy solicitor MORROW & CO. at (800) 662-5200.
