This Amendment No. 2 (this "Amendment") amends the Statement on Schedule 13D filed with the Securities and Exchange Commission on May 15, 2000, as previously amended (the "Schedule 13D"), by Mr. Sumner M. Redstone, National Amusements, Inc. ("NAI"), NAIRI, Inc. ("NAIRI"), Viacom Inc. ("Viacom"), Westinghouse CBS Holding Company, Inc. ("W/CBS HCI") and CBS Broadcasting Inc. ("CBSBI") (collectively, the "Reporting Persons"). This Amendment is filed with respect to the Class A Common Stock, $.01 par value per share (the "Class A Shares"), of Infinity Broadcasting Corporation, a Delaware corporation (the "Issuer"). Capitalized terms used in the Amendment and not otherwise defined herein have the meanings ascribed to such terms in the Schedule 13D. Item 3. Source and Amount of Funds or Other Consideration Item 3 is hereby amended and restated in its entirety to read as follows: "The Issuer's Class B 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 ("CBS"), of which CBSBI and W/CBS HCI were, respectively, indirect and direct wholly owned subsidiaries, with and into Viacom on May 4, 2000. In the proposed Merger reported in this Schedule 13D, as amended, and described in Item 4, Viacom will issue 0.592 of a share of Class B Common Stock, par value $.01 per share, of Viacom ("Viacom Class B Shares") for each outstanding Common Share of the Issuer." Item 4. Purpose of Transaction Item 4 is hereby amended and restated in its entirety to read as follows: "The Issuer's Class B 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, of which CBSBI and W/CBS HCI were, respectively, indirect and direct wholly owned subsidiaries, with and into Viacom on May 4, 2000. 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. On October 30, 2000, Viacom, IBC Merger Corp., a Delaware corporation and a direct wholly owned subsidiary of Viacom ("Merger Sub"), and the Issuer entered into a definitive agreement and plan of merger (the "Merger Agreement") pursuant to which the Issuer will merge with and into Merger Sub (the "Merger") and Viacom will acquire all the issued and outstanding Class A Shares not currently owned by Viacom. In the Merger, each outstanding Class A Share will be converted into the right to receive 0.592 of a Viacom Class B Share. Viacom anticipates that upon completion of the Merger, Viacom will seek to cause the Class A Shares to be delisted from trading on the New York Stock Exchange and to cause the termination of registration of the Class A Shares pursuant to Section 12 of the Securities and Exchange Act of 1934, as amended (the "Act"). A copy of the Merger Agreement is attached hereto as Exhibit 99.1 and is incorporated by reference herein. A copy of the press release issued by Viacom and the Issuer on October 31, 2000 is attached hereto as Exhibit 99.2. Other than as set forth herein, the Reporting Persons have no current plan or proposal which relates to, or would result in, any of the actions enumerated in subparagraphs (a) through (j) of Item 4 of Schedule 13D." Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to the Securities of the Issuer Item 6 of the Schedule 13D is hereby amended and restated in its entirety to read as follows: "Except as described herein, none of the Reporting Persons have entered into any, 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 amendment thereto, that was filed by certain of the Reporting Persons or any predecessor thereof. Viacom, as successor by merger to CBS, has assumed all the rights and obligations of CBS." Item 7.
