escrow in order to ensure that the  representations,  warranties  and  covenants
made by certain of the Selling  Stockholders  were not breached and to provide a
source of indemnification.

     Activision  will not  receive any of the  proceeds  from the sale of shares
being offered by the Selling Stockholders.

SELLING STOCKHOLDERS The following table reflects the beneficial ownership by the Selling Stockholders of an additional 32,759 shares of Activision common stock which are being released from escrow as described below. This table supplements and must be read in conjunction with the table set forth in the Prospectus dated May 8, 2002. Name of Selling Stockholder Number of Additional Shares of Common Stock --------------------------- ------------------------------------------- Christopher Scholz 3,276 Zachary Krefting 3,276 Richard D'Alosisio 3,276 Tom Teuscher 3,276 Scott Werner 3,276 Gerald T. O'Neil 3,276 Scholz Family Trust 13,103 Total 32,759 Activision entered into an agreement and plan of merger (the "Merger Agreement") with Activision Publishing, Inc., Shaba Acquisition, Inc., Shaba Games LLC and the Selling Stockholders. The transaction contemplated by the Merger Agreement was consummated on March 26, 2002. Pursuant to a warranty escrow agreement an aggregate of 32,759 shares of common stock, or approximately 10% of the total number of shares of Activision common stock issued in connection with the merger, were deposited in an escrow account in connection with the transaction (the "Escrow Shares"). The Escrow Shares were deposited in order to ensure that the representations, warranties and covenants by the Selling Stockholders under the Merger Agreement were not breached and in order to provide a source of indemnification to Activision pursuant to the Merger Agreement. The Escrow Shares are subject to release from escrow upon the expiration of the escrow period set forth in the escrow agreement and are to be issued to the Selling Stockholders to the extent not used for indemnification. In addition, an aggregate amount of 68,965 shares of common stock, or approximately 21.05% of the total number of shares of Activision common stock issued in connection with the merger, have been deposited in an escrow account (the "Product Escrow Shares"). The Product Escrow -2- Shares are subject to release from escrow and issuance to the Selling Stockholders upon fulfillment of certain software program delivery and ranking requirements and certain revenue requirements. This prospectus supplement reflects the release from escrow of all of the Escrow Shares as a result of the expiration of the escrow period. We will issue additional prospectus supplements that reflect any future issuances of the Product Escrow Shares. Prior to the acquisition of Shaba by Activision, Shaba was a party to various development agreements with Activision. Other than such contracts and the fact that the Selling Stockholders were members of Shaba, which became a wholly owned subsidiary of Activision on March 26, 2002 pursuant to the Merger Agreement, none of the Selling Stockholders listed above have had a material relationship with Activision within the past three years. -3-
