Purpose of Transaction Item 4 is amended as follows: "On August 1, 2004, Viacom, Stargate Acquisition Corp.

"The Merger Agreement provides for, among other things, the merger (the "Merger") of Stargate Two and SportsLine, and, at the option of Viacom, either SportsLine or Stargate Two will be the surviving corporation. As a result of the Merger, each Common Share will be converted into the right to receive $1.75 in cash, without interest, except for: (i) Common Shares held in treasury by SportsLine, all of which will be canceled without any payment; (ii) Common Shares owned by Viacom or its controlled affiliates; and (iii) Common Shares held by stockholders who validly exercise and perfect appraisal rights in accordance with Delaware law. "The Merger remains subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, including obtaining approval of the stockholders of SportsLine and the expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act. "Pursuant to the Merger Agreement, the board of directors of Stargate Two at the Effective Time (as defined in the Merger Agreement) will become the board of directors of the surviving corporation. In addition, the certificate of incorporation and bylaws of the surviving corporation will be, subject to certain exceptions, amended and restated at the Effective Time to conform to such organizational documents of Stargate Two. Upon completion of the Merger, Viacom will indirectly own all of the capital stock of SportsLine.

"The foregoing description of the Voting Agreements is qualified in its entirety by reference to the form of Voting Agreement entered into by Messrs. Levy, Mariani and Sanders, which is filed as Exhibit 2 to this Amendment. "Also on August 1, 2004, SportsLine and CBSBI entered into a letter agreement amending Sections 10.2(b), 10.2(c) and 10.2(d) of the Agreement (as amended through June 30, 2004) to provide that the issuance of Common Shares and payment of cash by SportsLine to CBSBI, and the related calculation of fair market value, provided for in those sections would occur on the earlier of (x) ten (10) trading days after the termination of the Merger Agreement in accordance with its terms and (y) the Effective Time, instead of on August 1, 2004.

Levy, Mariani and Sanders to have the right to terminate their employment with SportsLine for "good reason" (as defined) four months following the Effective Time; and (ii) if the Effective Time occurs prior to December 31, 2004 and Messrs. Levy, Mariani and Sanders are still employed by SportsLine on December 31, 2004, Viacom will cause the surviving corporation of the Merger to pay each of them their annual bonus for the year ended December 31, 2004 (such annual bonus to be determined pursuant to a formula previously established by compensation committee of SportsLine's board of directors, provided that for purposes of calculating EBITDA to determine such bonus, Viacom has agreed that certain transaction-related expenses and other payments will be excluded from SportsLine's 2004 operating expenses). The foregoing description of the letter agreements is qualified in its entirety by reference to the letter agreements attached as Exhibits 5, 6 and 7 to this Amendment.
