*     Effective for the full year 2003, the company is presenting its
      collaboration with Merck under the equity method of accounting. Under that
      method, the company records its share of the operating profits less its
      share of research and development costs in "Equity (Income)/Loss from
      Cholesterol Joint Venture." Included in this line for the full year 2003
      are the company's share of the operating profits of $113 million and a
      $20 million milestone payment, less its share of research and development
      costs of $79 million. It should be noted that the company incurs
      substantial costs, such as selling costs, that are not reflected in the
      equity income from the cholesterol joint venture and are borne by the
      overall cost structure of Schering-Plough.

**    Special Charges for the fourth quarter of 2003 included $179 million of
      employee termination costs, primarily related to the VERP in the United
      States, as well as $50 million of asset impairment charges related to
      certain fixed and intangible assets. Special charges for the full year
      2003 also included the $350 million provision to increase litigation
      reserves recorded in the third quarter, as well as $20 million of asset
      impairment charges related to manufacturing facility assets recorded in
      the second quarter. Special Charges in 2002 included a $150 million
      provision to increase litigation reserves.

      All figures rounded. Totals may not add due to rounding. N/M - not a
meaningful percentage.
