         ENVIRODYNE URGES SHAREHOLDERS TO REJECT ZAPATA DIRECTOR
 SLATE; OUTLINES MALCOLM GLAZER HISTORY OF USING CONTROL FOR PERSONAL GAIN

OAK BROOK, ILL. - May 1 - Envirodyne Industries, Inc. (Nasdaq SmallCap:
EDYN) Thursday released the following text of a letter to stockholders
by F. Edward Gustafson, chairman of the board, president and chief
executive officer:

Dear Fellow Stockholder:

        I wanted to remind you that the Company's Annual Meeting is set
to take place on May 16, 1997 and to encourage you to sign and return
the enclosed WHITE proxy card even if you have already done so.
Additionally, I wanted to acquaint you with Malcolm Glazer's history of
taking control of companies and then engaging in self-serving
transactions at the expense of other stockholders.

        Zapata Corporation may soon be sending you proxy materials along
with a blue proxy card. Zapata is looking to take control of Envirodyne.
We urge you not to sign or return any blue proxy card.

        Zapata is led by Malcolm Glazer, its Chairman and largest
stockholder, who wants control of Envirodyne without paying a fair
control premium to all our stockholders. The more you know about Mr.
Glazer, the clearer it becomes that Mr. Glazer wants what is best for
Mr. Glazer and that he has often used company-related transactions for
his personal gain.

        Zapata has also indicated that it intends to introduce a
proposal to eliminate the Company's Stockholder Rights Plan at the
Annual Meeting. This is simply another tactic by Zapata to make it
easier to acquire control of the Company without paying a fair price to
all stockholders. We urge you to vote AGAINST Zapata's proposal.
Enclosed is a supplement to our Proxy Statement describing in more
detail the Zapata proposal and the reasons we oppose it.

                        Malcolm Glazer's Approach

        We believe that Mr. Glazer's activities follow a pattern of
acquiring control of companies without actually buying the company and
then using that control for his personal gain.

        At Zapata, Mr. Glazer and his son, Avram gained two seats on the
board in July 1993. By the following July 1994 Malcolm Glazer had been
named Chairman of Zapata's board, and in August of 1994, he was elected
president and CEO. His son, Avram succeeded him as president and CEO in
March 1995.

           Transactions Involving Glazer-Controlled Companies

        Since early 1995 a series of questionable transactions between
Zapata and companies in which Glazer has an interest has prompted
lawsuits by stockholders and a former Zapata director.

 Glazer-Controlled Zapata Pays $18.8 Million For Glazer's Envirodyne Shares

        According to an October 7, 1996 Business Week article entitled
"Is Zapata the Glazers' Toy?", Mr. Glazer made a deal to sell his
holdings in Envirodyne to an investment banking firm, but the deal
collapsed in February 1995. Soon after, according to the article, Mr.
Glazer found another buyer for his shares -- Zapata. In August 1995,
Zapata paid the $18.8 million to a Glazer-controlled trust for such
shares. The payment was in the form of a promissory note bearing
interest at the prime rate and maturing in August 1997; Zapata has since
prepaid the promissory note.

        This transaction has enabled Mr. Glazer to get cash for his
Envirodyne shares and still retain control over them through his control
of Zapata.

 Glazer-Controlled Houlihan's Pays $10 Million to Advertise In Tampa Stadium

        In October 1995, Houlihan's Restaurant Group, Inc. (a
Glazer-controlled restaurant operator) agreed to pay $10 million for the
right to advertise its name in Tampa Stadium, where the Glazer-owned
Tampa Bay Buccaneers play. However, Houlihan's has only two restaurants
in Florida -- neither of which is in Tampa! According to a December 1995
article in the St. Petersburg Times, the money will be paid to a
partnership run by Glazer and his sons.

              A Zapata Director Sues the Glazers and Zapata

        In November 1995, Peter Holt resigned from the Zapata board in a
disagreement over Zapata's strategy to depart from energy services and
enter into the food service business. In his resignation letter, Mr.
Holt said: "The entry into food services...was predicated not upon the
identification of a more attractive industry segment than energy
services, but upon the make-up of Mr. Glazer's investment portfolio,
apparently the only source of candidates which are regarded, by those
responsible for the new strategy, as suitable acquisitions by Zapata."
Mr. Holt subsequently sued Zapata, Malcolm Glazer and Avram Glazer.

 Zapata Attempts to Purchase Glazer-Controlled Houlihan's for $80 Million

        In June 1996, Zapata and Houlihan's entered into a merger
agreement that called for Zapata to purchase Houlihan's for $80 million
- - a 30% premium over the pre-deal share price. Mr. Glazer, a 73% owner
of Houlihan's, stood to make $58.6 million on this transaction.
Stockholders of Zapata sued to block the purchase. The Court enjoined
the merger and as a result, Zapata abandoned the acquisition in October
1996.

                    Zapata Attempts A Share Buy-Back

        Then last December, Zapata announced plans to buy back up to 50%
of its outstanding stock at $4.50 per share. Mr. Glazer announced that
he planned to tender approximately one-third of his position, which
would have resulted in his receiving up to $13.5 million. In addition,
the buyback would have increased Mr. Glazer's proportional holdings in
Zapata. A lawsuit was filed by a stockholder in January 1997 to block
the buy-back.

        In February 1997, Michael Heisley offered to buy the Zapata
shares at a higher price that would benefit all stockholders. The
Glazer-controlled Zapata board rejected the offer and withdrew its
buy-back offer. We can only surmise that Mr. Glazer wanted both his
money and the ability to continue to control Zapata through his
tightly-controlled Zapata board.

        These transactions illustrate the way Mr. Glazer operates -
solely for his benefit. Your Board of Directors and I would like to
point out to Mr. Glazer that we have a fiduciary responsibility to
represent the interests of all stockholders, not just Mr. Glazer and his
interests.

              The Real Reasons Mr. Glazer Wants Envirodyne

        Mr. Glazer knows a good thing when he sees it. Envirodyne's cash
flow continues to grow, debt is being paid down as scheduled and Viskase
Corporation, a wholly owned subsidiary of the Company, was recently
awarded $102 million in damages in a patent infringement suit! Your
board is surprised by Mr. Glazer's recent actions because he has clearly
stated that he is in full agreement with the direction management is
taking the Company. He has never proposed a different strategic goal or
direction.

  Don't Let Envirodyne Fall Under the Control of Zapata and Mr. Glazer

        Your vote is necessary to ensure that Envirodyne remains an
independent company and does not fall under the control of Zapata and
Mr. Glazer. If Mr. Glazer wants control of Envirodyne, he should make a
bona fide offer that is fair to all stockholders.

        We urge you to sign, date and return the enclosed WHITE
Envirodyne proxy card. Your Board of Directors recommends that you vote
FOR the five Envirodyne nominees and AGAINST Zapata's proposal to
eliminate the Stockholder Rights Plan. We urge you not to sign any blue
proxy cards. 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

        Envirodyne has major interests in food packaging and the food
supplies industry, operating through three subsidiaries -- Viskase
Corporation, Clear Shield National, Inc. and Sandusky Plastics, Inc. The
company recently reported operating income of $39.7 million for the year
ended December 26, 1996 on net sales of $651.4 million. The company's
annual meeting of stockholders is scheduled for May 16 in Chicago.
