INTRODUCTORY STATEMENT This Amendment No. 1 to the original Tender Offer Statement on Schedule TO (the "Schedule TO") filed with the Securities & Exchange Commission on November 20, 2002 relates to an offer by Zapata Corporation, a Nevada corporation ("Zapata" or the "Company"), to purchase up to 500,000 of its outstanding shares of common stock, par value $.01 per share, for $28 per share, net to the seller in cash, upon the terms and subject to the conditions set forth in the Offer To Purchase dated November 20, 2002 and the related Letter Of Transmittal (which, together with any amendments or supplements hereto or thereto, collectively constitute the "Offer"). This Amendment No. 1 to Schedule TO is a termination of the Offer. The Company announced on December 6, 2002, that it rejected an unsolicited proposal to be acquired by an affiliate of an investment company that specializes in investments in commercial real estate loans. The proposal consisted of a non-binding letter of intent to acquire all of Zapata's outstanding shares for $35 per share in cash in a negotiated transaction. The proposal was subject to a number of contingencies, including due diligence and financing. After analyzing the nature and terms of the proposal, and other relevant information, Zapata's Board of Directors has determined that pursuing the proposal would not be in the best interest of Zapata or its stockholders. Zapata also announced on December 6, 2002 that its Board of Directors terminated its previously announced self-tender offer to purchase up to 500,000 shares of its common stock at a price of $28 per share. The Board approved the termination in light of the acquisition proposal announcement and the fact that the Company's stock has traded above the tender offer price since the self-tender offer announcement. Any shares previously tendered will be returned promptly to the tendering party. Zapata further announced that its Board authorized the Company to purchase up to 500,000 of its outstanding shares of common stock in the open market or privately negotiated transactions. The repurchases will be made only at such times as are permissible under the federal securities laws. ITEM 12. MATERIAL TO BE FILED AS AN EXHIBIT.
