 KENILWORTH, N.J., Nov. 13, 2002 - Schering-Plough Corporation (NYSE: SGP) today
announced that Richard Jay Kogan will retire as chief executive officer (CEO)
and president, and resign from the Board no later than the company's annual
meeting on April 22, 2003. To facilitate a smooth transition, Kogan has
relinquished today the position of chairman of the Board. Richard de J. Osborne,
a director of the company since 1988, has been appointed chairman and will
oversee the Board's search for a new CEO, which will commence immediately.
Kogan, 61, has been with Schering-Plough for over 20 years, and has served as
president and chief executive officer since 1996, and chairman, president and
chief executive officer since 1998.

        Kogan said, "I will be turning 62 in June 2003, and now that ZETIA has
been approved, I will step down the earlier of either the annual meeting in
April, or the Board's selection of my successor. I am proud of the company's
many achievements. Over the past two decades, we have built a good record in a
rapidly changing industry and I know that Schering-Plough is well prepared to
face the challenges ahead."

        Schering-Plough director Richard de J. Osborne said, "The Board of
Directors has accepted Mr. Kogan's decision to retire after a long and
distinguished career at Schering-Plough. The Board of Directors and the entire
Schering-Plough community thank Dick for his many years of dedicated
service to the company. We are grateful for his many contributions, and we
wish him the best.

                                     -more-


        "I will lead the Board's search for a new CEO and, as chairman, I plan
to be actively involved with the company during this transition period. The
Board will move quickly to complete its mission and to ensure Schering-Plough
achieves its potential for the benefit of all its constituencies," he concluded.

        Osborne, 68, retired as chairman of the board and chief executive
officer of ASARCO Incorporated in April 1999, following 24 years of employment.
He is currently non-executive chairman of the Board of Datawatch Corporation, a
director of Goodrich Corporation, NACCO Industries, Inc. and The Tinker
Foundation. He is also a director and treasurer of the Americas Society and the
Council of the Americas. He is also a member of the Council on Foreign Relations
and the Economic Club of New York. Mr. Osborne graduated from Princeton in 1956
with an A.B. Degree in economics.
