INTRODUCTORY NOTE.

         This Amendment No. 2 to Schedule 13D is being filed on behalf of 
Zapata Corporation, a Delaware corporation ("Zapata") to update certain
information set forth in the Schedule 13D of Envirodyne Industries, Inc. (the
"Issuer") originally filed by Zapata on August 17, 1995, as amended by Amendment
No. 1 to Schedule 13D filed on June 21, 1996.

ITEM 2.           IDENTITY AND BACKGROUND.

         Appendix A to Amendment No. 1 to Schedule 13D, containing information
with respect to executive officers and directors of Zapata is hereby amended and
superseded in its entirety by Appendix A hereto and is incorporated herein by
reference. Each such executive officer and director is a citizen of the United
States.


ITEM 4.           PURPOSE OF TRANSACTION

         Item 4 to the Schedule 13D is hereby supplemented as follows:

         By letter dated March 5, 1997, Avram A. Glazer, President and Chief
Executive Officer of Zapata and a director of the Issuer, asked F. Edward
Gustafson, Chairman of the Board of the Issuer, to pass on to the Issuer's
nominating committee a recommendation that the nominating committee ask Craig
Davis whether he would be willing to be included on the slate of nominees of the
Issuer's board of directors. Zapata understands that Craig Davis is a
representative of Bennett Restructuring Fund, L.P., a significant stockholder of
the Issuer.

         In his March 5, 1997 letter to Mr. Gustafson, Avram A. Glazer also
referred to a letter from Mr. Gustafson dated February 17, 1997 to Malcolm I.
Glazer and Avram A. Glazer, in which Mr. Gustafson had asserted that Malcolm I.
Glazer and Avram A. Glazer had made a "demand to nominate three new director
candidates to displace three existing directors," and stated that "without a
discussion of the sale of all of Envirodyne, the Board will not acquiesce to
your demand." Mr. Gustafson had further advised Malcolm I. Glazer and Avram A.
Glazer in his February 17, 1997 letter that the "Board is very willing to
entertain" a tender offer by Zapata for the shares of Envirodyne that Zapata
does not own, and that "[i]f an offer is not forthcoming, the Board will likely
seek a standstill agreement if you are to be re-nominated by the Board." Avram
A. Glazer previously responded to Mr. Gustafson, by letter dated February 27,
1997, that he had not made any demand, either on behalf of Zapata or himself,
and stated that "[a]ll that I asked you, not the nominating committee, to do was
consider and give me your reaction to an increase by three in the number of
board positions to be filled by designees of Zapata." In his March 5, 1997
letter to Mr. Gustafson, Avram A. Glazer reiterated that Mr. Gustafson's
February 27, 1997 letter contains an inaccurate premise - that a "demand" for
additional representation was made, and stated that "[a]s a result, we assume
that you will not follow through with your threat to deprive a 40% stockholder
of representation on the board." Avram A. Glazer requested that Mr. Gustafson
inform Zapata immediately if this assumption is not correct.

Dear Ed:

                  I have received your February 17 letter and thought I should
clear up an obvious misunderstanding. I did not make any demand, either on
behalf of Zapata or myself. All that I asked you, not the nominating committee,
to do was consider and give me your reaction to an increase by three in the
number of board positions to be filled by designees of Zapata. I did not ask you
to take any proposal, much less a demand, to the nominating committee or to the
rest of the board, as was apparently done. When you called Malcolm on Friday,
February 14 and told him that the nominating committee had rejected what you
termed my "proposal," you did not use the word demand or refer to a meeting of
all the members of the board excluding us. I trust this sets the record
straight.

                  On a related point, it seems inappropriate for any member of
the nominating committee with a potentially conflicting interest in the matter
to participate on any question concerning Zapata.

                                                          Very truly yours,

                                                          /s/ AVRAM A. GLAZER

                               [Zapata Letterhead]

March 5, 1997



Mr. F. Edward Gustafson
Chairman of the Board
Envirodyne Industries, Inc.
Suite 190

Oak Brook, Illinois 60521

Dear Ed:

                  This is an additional follow up to your letter to Malcolm
Glazer and me dated February 17, 1997.

                  As stated in my letter dated February 27, 1997, your letter of
February 17 contains an inaccurate premise - that we made a "demand" for
additional representation on the board. As a result, we assume that you will not
follow through with your threat to deprive a 40% stockholder of representation
on the board. Let us know if this assumption is not correct. Furthermore, we are
puzzled by your attribution of various views and positions to "the Board" since
there has not been any duly called board meeting at which the matters to which
you refer have been discussed.

                  We also ask that you pass on to the nominating committee our
recommendation that they ask Craig Davis of Bennett Restructuring Fund, L.P., a
significant Envirodyne stockholder, whether he would be willing to be included
on the slate of the board's nominees.

Very truly yours,

/s/ AVRAM A. GLAZER
