("CBSBI"), Westinghouse CBS Holding Company, Inc. ("W/CBS HCI"), Viacom Inc. ("Viacom"), NAIRI, Inc. ("NAIRI"), National Amusements, Inc. ("NAI") and Mr. Sumner M. Redstone with respect to the Common Stock, par value $.01 per share (the "Common Shares"), of SportsLine.com, Inc., a Delaware corporation ("SportsLine" or the "Issuer") with its principal executive office located at 2200 West Cypress Creek Road, Fort Lauderdale, Florida 33309. Item 4. Purpose of the Transaction -------------------------- Item 4 is amended and restated in its entirety as follows: The Issuer's Common Shares were acquired by the Reporting Persons, other than CBSBI and W/CBS HCI which previously owned the subject shares, pursuant to the merger of CBS Corporation, of which CBSBI and W/CBS HCI were, respectively, indirect and direct wholly owned subsidiaries, with and into Viacom on May 4, 2000. On March 5, 2003, CBSBI and the Issuer entered into a letter agreement (the "Letter Agreement"), pursuant to which: (i) the Agreement dated as of March 5, 1997, between the Issuer and CBSBI, as amended (the "Agreement"), was amended to provide that, in lieu of the Issuer's obligations to issue to CBSBI Common Shares having a fair market value of $20,000,000 on each of April 1, 2003 and July 1, 2004, the Issuer will: (A) issue to CBSBI on April 1, 2003, the lesser of (1) such number of Common Shares having a $20,000,000 fair market value on April 1, 2003, and (2) such number of Common Shares as would result in CBSBI and its affiliates' aggregate beneficial ownership interest in Issuer's Common Shares not exceeding 39.9% and defer the remainder of the $20,000,000 owing to CBSBI until July 1, 2004, and (B) issue or pay to CBSBI on July 1, 2004: (1) (a) such number of Common Shares having a $20,000,000 fair market value on July 1, 2004 plus such number of Common Shares having a fair market value on July 1, 2004 equal to the fair market value of the Common Shares deferred from April 2003 (as described in (A) above) (such aggregate value owing by SportsLine to CBSBI on July 1, 2004 being the "July 2004 Value") or, if that number exceeds 49.9%, (b) such number of Common Shares as would result in CBSBI and its affiliates' aggregate beneficial ownership interest in Issuer's Common Shares not exceeding 49.9%, (2) in cash the lesser of (a) the remaining amount of the July 2004 Value, if any, owing by the Issuer to CBSBI and (b) $5,000,000, and

Page 9 of 10 Pages (3) the remaining amount of the July 2004 Value, if any, owing to CBSBI, at the Issuer's election, in cash or Common Shares, based on the fair market value on July 1, 2004 (if the Issuer elects Common Shares, CBSBI may elect to defer the receipt of such Common Shares until October 1, 2005, and on October 1, 2005 CBSBI will receive Common Shares equal to the value of the deferred Common Shares based on the fair market value on October 1, 2005); and (ii) CBSBI withdrew its request made by letter dated December 23, 2002, to register 11,422,312 Common Shares on a Form S-3 shelf-registration statement pursuant to Section 3.4 of the CBS/SportsLine Stockholder Agreement dated March 5, 1997 between the Issuer and CBSBI, as amended. Any description of the Letter Agreement is qualified in its entirety by reference to the Letter Agreement attached as Exhibit 1 to this Amendment. The Reporting Persons have no current plan or proposal that relates to, or would result in, any of the actions enumerated in subparagraphs (a) through (j) of Item 4 of Schedule 13D. Notwithstanding the foregoing, the Reporting Persons may, at any time and from time to time, purchase additional Common Shares of the Issuer and may dispose of any and all Common Shares of the Issuer held by them. Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer. ----------------------------------- Item 6 is amended as follows: "Except as described in Item 4 above, none of the Reporting Persons have entered into, or amended any existing agreement with respect to the Common Shares or other securities of the Issuer since the prior statement on Schedule 13D, or amendments thereto, filed by certain of the Reporting Persons and any predecessor thereof. "The information set forth under Item 4 above is incorporated by reference." Item 7. Material to be Filed as Exhibits. -------------------------------- Exhibit 1 Letter Agreement dated March 5, 2003, between CBS Broadcasting Inc. and SportsLine.com, Inc., incorporated by reference to Exhibit 99.2 to the Current Report on Form 8-K of SportsLine.com, Inc., filed with the Securities and Exchange Commission on March 6, 2003.
