(1) Amounts represent interest income related to the exercise of warrants and
    UPO. Proceeds from assumed exercise of warrants and UPO were assumed to be
    used first to repurchase outstanding shares (limited to 20% of total
    shares outstanding) and the remainder to pay debt and be invested.
(2) Shares issued from assumed exercise of options, warrants and UPO include
    the number of incremental shares which would result from applying the
    treasury stock method for options, warrants and UPO. (APB 15, paragraph 38
