          Item 4 of the Statement is hereby amended and supplemented by
adding the following at the end thereof as follows:

          The transactions contemplated by the Management Services Agreement
have been consummated.  The following persons (the "Viacom Designees") have
been designated by Viacom for election to the Issuer's Board of Directors:
(i) Frank J. Biondi, Jr., President, Chief Executive Officer of Viacom,
(ii) Phillipe P. Dauman, Executive Vice President, General Counsel, Chief
Administrative Officer and Secretary of Viacom, (iii) J. Brian McGrath,
(iv) John L. Muething, and (v) Sumner M. Redstone, Chairman of the Board of
Directors of Viacom. In addition, H. Wayne Huizenga and George D. Johnson, Jr.
have resigned from the Board of Directors of the Issuer.  Thereafter, the
remaining directors, Messrs. Berrard and Flynn, appointed the five Viacom
Designees to the Issuer's Board of Directors.  As contemplated by the
Management Services Agreement, Blockbuster Discovery Investment, Inc.
("BDI"), an indirect wholly owned subsidiary of Viacom, and the Issuer
entered into a Warrant Agreement dated as of May 24, 1995 (the "Warrant

          Pursuant to the Stock Purchase Agreement, BDI has purchased
3,823,647 shares of Common Stock from the Sellers.  The source of funds
for this purchase was working capital of Viacom.

          Pursuant to the Letter Agreement, a definitive Asset Purchase
Agreement dated as of May 24, 1995 (the "Asset Purchase Agreement") was
entered into by Blockbuster Family Fun, Inc. ("BFF"), Blockbuster
Amusement Holding Corporation ("BAHC"), Discovery Zone L.P. ("DZILP") and
the Issuer.  Pursuant to the Asset Purchase Agreement, the assets of
BFF, comprised of two entertainment centers operating under the name and
mark of "Block Party", were sold to DZLIP in exchange for a $13,214,550
ten-year subordinated note of DZLIP, guaranteed by the Issuer.  As
contemplated by the Asset Purchase Agreement, (i) Viacom has agreed to
assign and transfer Viacom's right, title and interest certain intellectual
property assets to DZLIP and (ii) Viacom and Blockbuster Entertainment
Inc. have licensed the mark "Block Party" to DZILP pursuant to a five year
royalty-free license agreement.
