*   For the nine months ended September 30, 2004, earnings were insufficient to
    cover fixed charges by $264.

** For the year ended December 31, 2003, earnings were insufficient to cover
fixed charges by $70.

"Earnings" consist of (loss)/income before income taxes and equity income, plus
fixed charges (other than capitalized interest and preference dividends),
amortization of capitalized interest and distributed income of equity investee.
"Fixed charges" consist of interest expense, capitalized interest, preference
dividends and one-third of rentals which Schering-Plough believes to be a
reasonable estimate of an interest factor on leases.
