(1) Percentages are based on 52,681,131 shares of common stock that were issued and outstanding as of November 16, 2001, effected for the stock split. (2) This amount does not include the following, which are more fully described below: (i) 230,988 shares of Common Stock subject to certain software program delivery and revenue and certain escrow requirements; and (ii) 23,098 shares of Common Stock to be issued to certain Selling Stockholders upon completion of certain software program delivery and revenue requirements. The Company entered into an agreement and plan of merger (the "Merger Agreement") with Activision Publishing Inc., Treyarch Invention LLC ("Treyarch"), Don Likeness, Peter Akemann, Eric Steinmann, Shawn Capistrano and Eric Steinmann, as representative of the persons listed on Schedule 1 thereto (the "Members"). The transaction contemplated by the Merger Agreement was consummated on October 1, 2001. Pursuant to a warranty escrow agreement an aggregate of 230,988 shares of Common Stock, or twenty-two percent (22%) of the total number of shares of Common Stock issued have been deposited in an escrow account in connection with the transaction (the "Escrow Shares"). The Escrow Shares have been deposited in order to ensure that the representations, warranties and covenants made by the former Treyarch Members under the Merger Agreement are not breached and in order to provide a source of indemnification to Activision pursuant to the Merger Agreement. In addition, the Escrow Shares are subject to release from escrow upon fulfillment of certain software program delivery and ranking requirements and certain revenue requirements, as described in the Merger Agreement. In the event certain of the software program delivery and ranking requirements are met, certain of the Selling Stockholders are entitled to receive, in addition to the Escrow Shares, 23,098 shares of Common Stock. We will issue a prospectus supplement to reflect any increase in the number of shares of Common Stock offered for sale in the event the conditions described above are fulfilled. Prior to the acquisition of Treyarch by Activision, Treyarch was a party to various development agreements with Activision. Other than such contracts and the fact that the Selling Stockholders are employees of Treyarch, which became a wholly owned subsidiary of Activision on October 1, 2001 pursuant to the Merger Agreement, none of the Selling Stockholders has had a material relationship with the Company within the past three years.
