           VIACOM AGREES TO ACQUIRE ALL OUTSTANDING SHARES OF INFINITY
                Companies Enter Into Definitive Merger Agreement

New York, NY, October 31, 2000 - Viacom Inc. (NYSE: VIA, VIA.B) and Infinity
Broadcasting Corporation (NYSE: INF) announced today that they have entered into
a definitive merger agreement under which Viacom will acquire all 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. The merger is expected to be completed in the first quarter of
2001.

The exchange ratio represents an increase from Viacom's previously disclosed
offer of 0.564 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 64.3% 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 special
committee has received the opinions of its financial advisors that, as of the
date of the merger agreement, the exchange ratio is fair to the stockholders of
Infinity, excluding Viacom and its affiliates, from a financial point of view.
The transaction was also unanimously approved by the Board of Directors of
Viacom.

stronger and even better positioned to deliver superior returns to stockholders.
