Note: Six copies of this statement, including all exhibits, should be filed with the Commission. See Rule 13d-1(a) for other parties to whom copies are to be sent. Page 1 of 3 Pages 2 INTRODUCTORY NOTE. This Amendment No. 3 to Schedule 13D is being filed on behalf of Zapata Corporation, a Delaware corporation ("Zapata"), to supplement 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 Nos. 1 and 2 to Schedule 13D filed on June 21, 1996 and March 10, 1997, respectively. ITEM 4. PURPOSE OF TRANSACTION Item 4 to the Schedule 13D is hereby supplemented as follows: On March 27, 1997, pursuant to an amendment to the Issuer's Bylaws filed with the Securities and Exchange Commission on March 20, 1997 (the "Amended Bylaws"), Zapata provided the Issuer with notice of Zapata's intent to nominate Malcolm I. Glazer, Avram A. Glazer, Bryan G. Glazer, Edward S. Glazer and Robert V. Leffler, Jr. (the "Nominees") for election to the Board of Directors of the Issuer at the 1997 Annual Meeting of Stockholders of the Issuer (the "1997 Annual Meeting"). Malcolm I. Glazer and Avram A. Glazer currently are directors of both the Issuer and Zapata. Robert V. Leffler, Jr. currently serves on the Board of Directors of Zapata. Malcolm I. Glazer is the father of Avram A. Glazer, Bryan G. Glazer and Edward S. Glazer. If all of the Nominees are elected as directors of the Issuer, the Nominees would represent more than a majority of the Issuer's seven-member Board of Directors. Each Nominee has provided the Issuer with a written consent stating his willingness to serve on the Issuer's Board of Directors, if elected. On March 27, 1997, pursuant to the Amended Bylaws, Zapata also provided the Issuer with notice of Zapata's intent to bring a proposal (the "Proposal") before the 1997 Annual Meeting recommending that the Board of Directors of the Issuer take appropriate action to redeem as soon as practicable the Rights issued under the Rights Agreement between the Issuer and Harris Trust & Savings Bank dated as of June 26, 1996 (the "Rights Agreement") or otherwise terminate the rights plan and not implement any other stockholder rights plan without a binding vote of the Issuer's stockholders. Because the Rights Agreement effectively precludes Zapata from acquiring 41% or more of the Issuer's common stock, par value $0.01 per share ("Common Stock"), without a specified approval of the Issuer's Board of Directors, the redemption of the Rights as contemplated by the Proposal would increase the degree to which the Zapata could purchase additional shares of Common Stock. Zapata may consider the acquisition of additional shares of Common Stock or proposing a merger with, or acquisition of, the Issuer in the future. Zapata intends to appear in person or by proxy at the meeting of stockholders to nominate the Nominees and to bring the Proposal before the 1997 Annual Meeting.
