This communication is filed pursuant to Rules 165 and 425 promulgated under the Securities Act of 1933, as amended Subject Company: Infinity Broadcasting Corporation Commission File No.: 001-14599 INFINITY ANNOUNCES MEETING OF STOCKHOLDERS TO VOTE ON MERGER WITH VIACOM Companies Continue To Expect Completion of Merger In First Quarter of 2001 New York, New York, January 5, 2001 - Infinity Broadcasting Corporation (NYSE: INF) and Viacom Inc. (NYSE: VIA and VIA.B) announced today that Infinity will hold a meeting of its stockholders to seek approval on the merger of the two companies. The companies decided to seek stockholder approval after a recent Delaware Chancery Court decision involving another corporation (Digex, Inc. Shareholders Litigation) created uncertainty about whether such a vote might be required for Delaware corporations, such as Infinity. The stockholder meeting is expected to occur in the first quarter of 2001. The closing of the merger is expected to occur promptly following the meeting. The companies also announced that in a show of support for the merger, Infinity's two largest stockholders other than Viacom, Arturo R. Moreno and William S. Levine, have agreed to vote their shares in favor of the transaction. Mel Karmazin, President and Chief Operating Officer of Viacom, said, "Our stockholders have been overwhelmingly enthusiastic about the transaction, which is a win-win for Viacom and Infinity. In light of the Delaware decision, we decided to seek a shareholder vote to eliminate any uncertainty created by the ruling." Stockholders of record on January 16, 2001 will be entitled to vote on the proposed merger. Infinity will seek approval of two-thirds of the outstanding voting shares, other than shares owned by Viacom or subject to the voting agreement. As previously announced, Infinity and Viacom have entered into a definitive agreement under which Viacom will acquire all of the issued and outstanding shares of Infinity Common Stock that it does not currently own for 0.592 of a share of Viacom Class B Common Stock per share of Infinity Class A Common Stock. Viacom currently holds 100% of the Infinity Class B Common Stock, which represents approximately 64.2% of the total outstanding shares of the Infinity Class A and Class B Common Stock and approximately 90% of the combined voting power of the Infinity Class A and Class B Common Stock. Viacom does not currently hold any of the Infinity Class A Common Stock. The Infinity Board of Directors approved the merger agreement after receiving the unanimous recommendation of a special committee of independent directors, which was advised by separate legal and financial advisors. The transaction was also unanimously approved by the Board of Directors of Viacom.
