INDEPENDENT AUDITORS’ REPORT

To the Participants of the
Schering-Plough Employees’ Savings Plan:

We have audited the accompanying statements of net assets available for benefits of Schering-Plough Employees’ Savings Plan (the “Plan”) as of December 31, 2002 and 2001, and the related statement of changes in net assets available for benefits for the year ended December 31, 2002. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2002 and 2001, and the changes in net assets available for benefits for the year ended December 31, 2002, in conformity with accounting principles generally accepted in the United States of America.

Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental Schedule of Assets Held at End of Year is presented for the purpose of additional analysis and is not a required part of the basic financial statements, but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This schedule is the responsibility of the Plan’s management. Such schedule has been subjected to the auditing procedures applied in our audit of the basic 2002 financial statements, and, in our opinion, is fairly stated in all material respects when considered in relation to the basic 2002 financial statements taken as a whole.

SCHERING-PLOUGH EMPLOYEES’ SAVINGS PLAN
NOTES TO FINANCIAL STATEMENTS

1. General

The Schering-Plough Employees’ Savings Plan (the “Plan”) is a defined contribution plan available to all United States employees of Schering-Plough Corporation (the “Company”) and its participating subsidiaries. Generally, all such employees are eligible to participate in the Plan on the date of employment. Schering Corporation is the Plan’s sponsor.

2. Summary of Significant Accounting Policies

Basis of Accounting - The financial statements of the Plan have been prepared on an accrual basis in accordance with accounting principles generally accepted in the United States of America.

The financial statements were prepared in accordance with the financial reporting requirements of the Employee Retirement Income Security Act of 1974 (“ERISA”) as permitted by the Securities and Exchange Commission.

Investment Valuation and Income Recognition - The Plan’s investments are stated at fair value. Shares of registered investment companies are valued at quoted market prices, which represent the net asset value of shares held by the Plan at year-end.

The Schering-Plough Stock Fund is valued using the unit accounting method whereby a participant’s account value is expressed in units of participation rather than number of shares of Schering-Plough common stock.

The closing stock prices of Schering-Plough Corporation common stock at December 31, 2002 and December 31, 2001 were $22.20 and $35.81, respectively.

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date. Dividends recorded in the Schering-Plough Stock Fund are reinvested in Schering-Plough common stock units.

Participant loans are valued at cost which approximates fair value.

Withdrawals and Benefit Payments - Withdrawals and benefit payments are recorded when paid.

Use of Estimates - The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes

($ in 000’s except per share amounts)

therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

Risks and Uncertainties - The Plan provides for various investment options. Investment securities, in general, are exposed to various risks, such as interest rate, credit and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in value of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits.

3. Plan Description

The following brief description of the Plan is provided for general information purposes only. Participants should refer to the Plan document for more complete information.

Salary Deferral Contributions - Each year participants may contribute from 1% to 50% of pretax annual compensation, up to annual IRS maximums. Highly compensated employees are limited to 6% of pretax annual compensation, up to annual IRS maximums. Catch up contributions are available to employees over age 50.

Participant Accounts - Each participant’s account is credited with the participant’s contribution and earnings thereon. Participants have a non-forfeitable right to their contributions plus (minus) actual earnings (losses) thereon which vest fully and immediately.

years, except loans relating to a principal residence, which are repayable over a period not to exceed 20 years.

Payment of Benefits - On termination of service due to death, disability or retirement, a participant may elect to receive either a lump sum amount or installments not to exceed the life expectancy of the participant.

Distribution of all or a portion of a participant’s account, prior to termination of employment, may be granted by the Company in the case of financial hardship. Active participants may elect to withdraw all or a portion of their accounts at any time after age 70.

4. Plan Termination

Although it has not expressed any intent to do so, the Company has the right under the Plan to terminate the Plan subject to provisions of ERISA.

5. Tax Status

The Internal Revenue has determined and informed the Company by letter dated May 9, 2003 that the Plan and related trust are designed in accordance with applicable sections of the Internal Revenue Code (IRC). The Plan’s tax counsel believes that the Plan is designed in compliance with the applicable requirements of the IRC, and the Plan Administrator believes that the Plan is being operated in compliance with the applicable requirements of the IRC.

6. Party-in-interest

Contributions are held and managed by The Vanguard Group, Inc. (the “Trustee”), which invests cash received, interest and dividend income and makes distributions to the participants. The Trustee also administers the payment of interest and principal on the participant loans. These transactions qualify as permitted party-in-interest transactions.

Certain Plan investments are shares of mutual funds managed by the Vanguard Fiduciary Trust Company, a wholly-owned subsidiary of The Vanguard Group, Inc. The Vanguard Group, Inc. is the trustee as defined by the Plan. These transactions qualify as permitted party-in-interest transactions.

Certain Plan investments are shares of the Company’s stock. These transactions qualify as permitted party-in-interest transactions.
