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

(b) 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.

(c) The Preferred Stock and related dividend requirement had an anti-dilutive
    effect on earnings per share in 1996 and 1995, and, therefore, were
    excluded from the fully diluted earnings per share computation.
