DISCLOSURE NOTICE

CAUTIONARY FACTORS THAT MAY AFFECT FUTURE RESULTS (CAUTIONARY STATEMENTS UNDER
THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995).

This 8-K, including each Exhibit, and other written and oral statements made
from time to time by Schering-Plough may contain "forward-looking statements"
within the meaning of the Securities Litigation Reform Act of 1995.
Forward-looking statements relate to expectations or forecasts of future events.
They use words such as "anticipate," "believe," "could," "estimate," "expect,"
"forecast," "project," "intend," "plan," "potential," "will," and other words
and terms of similar meaning in connection with a discussion of potential future
events, circumstances or future operating or financial performance. You can also
identify forward-looking statements by the fact that they do not relate strictly
to historical or current facts.

In particular, forward-looking statements include statements relating to future
actions, prospective products, the status of product approvals, future
performance or results of current and anticipated products, sales efforts,
development programs, expenses and our programs to reduce expenses, the number
of employees accepting Schering-Plough's planned voluntary early retirement
program and the cost of and savings from that program, the outcome of
contingencies such as litigation and investigations, growth strategy and
financial results.

Any or all of our forward-looking statements here or in other publications may
turn out to be wrong. Our actual results may vary materially, and there are no
guarantees about the performance of Schering-Plough stock. Schering-Plough does
not assume the obligation to update any forward-looking statement.

You should carefully consider any forward-looking statement and should
understand that many factors could cause actual results to differ from
Schering-Plough's forward-looking statements. These factors include inaccurate
assumptions and a broad variety of other risks and uncertainties, including some
that are known and some that are not. Although it is not possible to predict or
identify all such factors, they may include the following:

o    A significant portion of net sales are made to major pharmaceutical and
     health care products distributors and major retail chains in the United
     States. Consequently, net sales and quarterly growth comparisons may be
     affected by fluctuations in the buying patterns of major distributors,
     retail chains and other trade buyers. These fluctuations may result from
     seasonality, pricing, wholesaler buying decisions or other factors.

o    Competitive factors, including technological advances attained by
     competitors, patents granted to competitors, new products of competitors
     coming to the market, new indications for competitive products or generic
     prescription or OTC competition as Schering-Plough's products mature and
     patents expire on products.

o    Increased pricing pressure both in the United States and abroad from
     managed care organizations, institutions and government agencies and
     programs. In the United States, among other developments, consolidation
     among customers may increase pricing pressures and may result in various
     customers having greater influence over prescription decisions through
     formulary decisions and other policies.

o    Government laws and regulations (and changes in laws and regulations)
     affecting domestic and international operations and the enforcement thereof
     including, among other laws and regulations, those resulting from
     healthcare reform initiatives and Medicare drug benefit and drug
     importation legislation in the United States at the state and federal level
     and in other countries, as well as laws and regulations relating to trade,
     antitrust, monetary and fiscal policies, taxes, price controls and possible
     nationalization.

o    Patent positions can be highly uncertain and patent disputes are not
     unusual. An adverse result in a patent dispute can preclude
     commercialization of products or negatively impact sales of existing
     products or result in injunctive relief and payment of financial remedies.


                                       3




o    Uncertainties of the FDA approval process and the regulatory approval
     processes of non-U.S. countries, including, without limitation, delays in
     approval of new products.

o    Failure to meet Good Manufacturing Practices established by the FDA and
     other governmental authorities can result in delays in the approval of
     products, release of products, seizure or recall of products, suspension or
     revocation of the authority necessary for the production and sale of
     products, fines and other civil or criminal sanctions. The resolution of
     manufacturing issues with the FDA discussed in this report are subject to
     substantial risks and uncertainties. These risks and uncertainties,
     including the timing, scope and duration of a resolution of the
     manufacturing issues, will depend on the ability of Schering-Plough to
     assure the FDA of the quality and reliability of its manufacturing systems
     and controls, and the extent of remedial and prospective obligations
     undertaken by Schering-Plough.

o    Difficulties in product development. Pharmaceutical product development is
     highly uncertain. Products that appear promising in development may fail to
     reach market for numerous reasons. They may be found to be ineffective or
     to have harmful side effects in clinical or pre-clinical testing, they may
     fail to receive the necessary regulatory approvals, they may turn out not
     to be economically feasible because of manufacturing costs or other factors
     or they may be precluded from commercialization by the proprietary rights
     of others.

o    Efficacy or safety concerns with respect to marketed products, whether or
     not scientifically justified, leading to recalls, withdrawals or declining
     sales.

o    Major products such as CLARITIN, CLARINEX, INTRON A, PEG-INTRON, REBETOL
     Capsules and NASONEX accounted for a material portion of Schering-Plough's
     2002 revenues. If any major product were to become subject to a problem
     such as loss of patent protection, OTC availability (as indicated above for
     CLARITIN and its current and potential OTC competition), previously unknown
     side effects; if a new, more effective treatment should be introduced; or
     if the product is discontinued for any reason, the impact on revenues could
     be significant. Further such information about important new products such
     as ZETIA or other important products in our pipeline may impact future
     revenues.

o    Legal factors, including product liability claims and other litigation,
     government investigations, patent disputes with competitors and
     environmental concerns, any of which could preclude commercialization of
     products or negatively affect the profitability of existing products.

o    Economic factors over which Schering-Plough has no control, including
     changes in inflation, interest rates and foreign currency exchange rates.

o    Instability, disruption or destruction in a geographic region important to
     us - due to the location of our manufacturing facilities, distribution
     facilities or customers - regardless of cause, including war, terrorism,
     riot, civil insurrection or social unrest; and natural or man-made
     disasters, including famine, flood, fire, earthquake and storm.

o    Changes in tax laws including changes related to taxation of foreign
     earnings.

o    Changes in accounting standards promulgated by the American Institute of
     Certified Public Accountants, the Financial Accounting Standards Board or
     the Securities and Exchange Commission that would require a significant
     change to Schering-Plough's accounting practices.

For further details and a discussion of these and other risks and uncertainties,
see Schering-Plough's Securities and Exchange Commission (SEC) filings,
including Schering-Plough's 2003 Second Quarter 10-Q filed with the Commission
on July 31, 2003 and future SEC filings.
