(1)   The variable common rights (the "VCRs") matured on September 29, 1995. The
      Company issued approximately 6.1 million shares of Viacom Inc. Class B
      Common Stock, or .022665 of a share of Viacom Inc. Class B Common Stock
      per VCR, to settle its obligation under the VCRs.

(2)   The contingent value rights (the "CVRs") matured on July 7, 1995. The
      Company paid approximately $81.9 million in cash of approximately $1.44
      pen CVR to settle its obligation.

(3)   For the years ended December 31, 1996, 1995, and 1994, the assumed
      conversion of preferred stock had an anti-dilutive effect on earnings per
      share, resulting from the assumed reduction in preferred stock dividends,
      and therefore was excluded from the fully diluted earnings per share
      calculation.
