SCHERING-PLOUGH REPORTS FINANCIAL RESULTS
FOR FIRST QUARTER OF 2007

Company Sustains Momentum into First Quarter of 2007,
Moves Ahead on Planned Organon BioSciences Acquisition

KENILWORTH, N.J., April 19, 2007 – Schering-Plough Corporation (NYSE: SGP) today reported financial results for the first quarter of 2007 and commented on its planned acquisition of Organon BioSciences N.V. (OBS).

“Our first quarter performance demonstrates that we continue to hone our competitive edge, extend our core businesses and deliver very strong results,” said Fred Hassan, chairman and CEO. “We sustained the momentum in the first quarter that we built in our business over the last three years. At the same time, we are gaining momentum in R&D. And our planned combination with OBS and its Organon, Intervet and Nobilon businesses promises to build on that momentum.”

For the 2007 first quarter, net income available to common shareholders increased to $543 million or 36 cents per common share on a GAAP basis versus net income of $350 million or 24 cents per common share in the 2006 first quarter. Excluding charges of $96 million related to three upfront licensing payments included in research and development expenses, earnings per share for the 2007 first quarter would have been 42 cents (see table below). The 2006 first quarter includes income of $22 million or approximately 2 cents per share resulting from the cumulative effect of the adoption of SFAS 123R related to stock-based compensation.

GAAP net sales for the 2007 first quarter totaled $3.0 billion, up 17 percent versus the 2006 first quarter. Including an adjustment of an assumed 50 percent of global cholesterol joint venture net sales (see table below), Schering-Plough’s adjusted net sales (hereinafter referred to as “adjusted sales”) for the 2007 first quarter would have totaled $3.6 billion, a 21 percent increase compared to $2.9 billion on a similar adjusted basis in the 2006 first quarter. Schering-Plough does not record sales of its cholesterol joint venture with Merck & Co., Inc. (Merck), as the venture is accounted for under the equity method.

“Schering-Plough has now delivered 10 consecutive quarters of double-digit adjusted sales growth on a year-over-year basis,” said Hassan. “We are growing our core businesses across all major geographic regions. We have sustained the strength of our cholesterol, respiratory, immunology and

oncology franchises. Our Animal Health and Consumer Health Care businesses are also growing. Our strategy of growing the top line while maintaining financial discipline is clearly paying off – with higher bottom-line earnings and growing financial headroom.”

Along with strong business results, Hassan emphasized that, “Schering-Plough is gaining momentum in R&D. We are moving forward with four ‘fast-track’ compounds discovered in our own labs.” He noted that the U.S. Food and Drug Administration grants “fast track” status to compounds with potential to address serious unmet medical needs. The four projects are: a novel oral thrombin receptor antagonist (TRA) for acute coronary syndrome and secondary prevention; vicriviroc, a CCR5 receptor antagonist for HIV; boceprevir, a protease inhibitor for hepatitis C; and an A2a receptor antagonist for patients with Parkinson’s disease.

In cardiovascular care, Schering-Plough “is emerging as a leader, both in the marketplace and in clinical research,” said Hassan. He pointed to the approval of ZETIA in Japan announced yesterday and to the Phase II results for TRA reported in a late-breaking clinical trial session at last month’s American College of Cardiology (ACC) meeting. Results at ACC showed that TRA, a novel selective antiplatelet therapy, met its primary endpoint of demonstrating no increase in major and minor bleeding when added to standard antiplatelet therapy. Schering-Plough also announced yesterday that two large phase III trials are being planned for TRA, with patients expected to begin treatment in the trials later this year.

Schering-Plough has also extended its research pipeline by capturing external innovation through business development and licensing agreements. Over the last three years, the company has entered into a series of agreements in support of its key therapeutic areas, including respiratory, infectious diseases, cardiovascular, oncology, immunology, as well as in Consumer Health Care and Animal Health. Examples include last month’s agreement with Merck to develop an ezetimibe (ZETIA) and atorvastatin fixed-dose combination medicine for lowering cholesterol. This could further realize the value of Schering-Plough’s ZETIA discovery. Other examples include the company’s in-licensing from Anacor Pharmaceuticals of AN2690 for the treatment of onychomycosis, and from ALK-Abelló of sublingual tablet-based immunotherapies for various allergies.

Organon BioSciences Update

“Since we began the Action Agenda four years ago, Schering-Plough has been on a journey of transformation. Our success in advancing through the Stabilize and Repair phases, through the Turnaround phase in just one year, and now into the Build the Base phase, has given us the strength and resources to build our business through a significant acquisition. The Organon BioSciences acquisition that we announced in March will

- 3 -

be an important part of our Build the Base phase. As we move forward, we are drawing upon this management team’s demonstrated track record of creating value with large, complex transactions – including transatlantic combinations,” said Hassan.

Following the March 12 announcement, Schering-Plough immediately began work on key activities that are part of the process for completing the transaction. These activities include conferring with social partners, such as Works Councils, and working through the antitrust process in various jurisdictions, including in the United States and EU. Schering-Plough and Organon BioSciences also began to develop a process that would be initiated for integration once the key activities are completed and the transaction has closed. The transaction is expected to be completed by year-end 2007 and remains subject to certain closing conditions, including regulatory approvals.

“Five weeks after the announcement, we are now even more convinced that this is the right deal, at the right time,” said Hassan. “Strategically, scientifically and financially – this combination promises to be an excellent and complementary fit. Looking ahead, our primary job will be to sustain the momentum we have gained in our business and research operations, while achieving a smooth and efficient integration with Organon BioSciences. Then, together, we will work toward building a new kind of health care company that can meet the needs of our customers and deliver high performance for the long term.”

First Quarter 2007 Results

For the 2007 first quarter, Schering-Plough reported net income available to common shareholders of $543 million or 36 cents per common share on a GAAP basis. Excluding charges of $96 million or 6 cents per share related to three upfront licensing payments that are included in research and development expense, earnings per share for the 2007 first quarter would have been 42 cents. For the 2006 first quarter, Schering-Plough reported net income of $350 million or 24 cents per common share, which includes income of 2 cents per share resulting from the cumulative effect of the adoption of SFAS 123R related to stock-based compensation.

GAAP net sales for the 2007 first quarter totaled $3.0 billion, up 17 percent as compared to the first quarter of 2006. The sales growth versus 2006 reflects a 3 percent favorable impact from foreign exchange.

Global cholesterol joint venture net sales, which include VYTORIN and ZETIA, totaled $1.2 billion in the 2007 first quarter, a 48 percent increase compared to net sales of $778 million in the comparable 2006 period. Schering-Plough does not record sales of its cholesterol joint venture with Merck as the venture is accounted for under the equity method. Including an adjustment of an assumed 50 percent of the global cholesterol joint venture net sales, Schering-Plough’s adjusted sales for the

- more -

2007 first quarter would have been $3.6 billion, a 21 percent increase, compared to $2.9 billion on a similar adjusted basis in the 2006 first quarter.

Overall, Schering-Plough shares in approximately 50 percent of the profits of the joint venture with Merck, although there are different profit-sharing arrangements for the cholesterol products in countries around the world. There is a separate co-marketing agreement with Bayer for ZETIA in Japan, where the product was just granted regulatory approval. ZETIA will not become available in Japan until National Health Insurance Reimbursement price listing. Schering-Plough records its share of the income from operations in “Equity income from cholesterol joint venture,” which totaled $487 million in the 2007 first quarter versus $311 million in the first quarter of 2006. Schering-Plough noted that it incurs substantial costs such as selling, general and administrative costs that are not reflected in “Equity income from cholesterol joint venture” and are borne by its overall cost structure.

Sales of REMICADE increased 34 percent to $373 million in the first quarter of 2007, driven by growth across all indications. REMICADE is a treatment for immune-mediated inflammatory disorders that Schering-Plough markets in countries outside the United States (except in Japan and certain other Asian markets) for rheumatoid arthritis, early rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, plaque psoriasis, Crohn’s disease and ulcerative colitis. REMICADE sales were higher primarily due to continued market growth and expanded indications for its use.

Global NASONEX sales rose 24 percent to $284 million versus the 2006 period, primarily due to growth in core global markets.

Sales of PEGINTRON for hepatitis C increased 10 percent to $217 million in the 2007 first quarter due to growth in the United States and many international markets.

Global CLARINEX sales in the first quarter of 2007 were $204 million compared to $160 million in the prior period. International sales of prescription CLARITIN were $112 million in the first quarter compared to 2006 sales of $101 million.

Sales of TEMODAR, a treatment for certain types of brain tumors, grew 20 percent to $196 million due primarily to continued utilization in Europe for treating newly diagnosed glioblastoma multiforme (GBM), which is the most prevalent form of brain cancer, and the product’s 2006 launch in Japan. The growth rate for TEMODAR is expected to moderate as significant penetration in U.S. and EU markets has already been achieved in the treatment of GBM. Also reporting higher sales in the quarter was CAELYX, up 21 percent to $62 million, as a result of increased use in treating ovarian and breast cancer.

Among other prescription products posting higher sales in the 2007 first quarter was the antibiotic AVELOX, up 43 percent to $115 million, primarily as a result of increased market share.

Consumer Health Care sales were $345 million in the 2007 first quarter, up 11 percent versus the 2006 period due primarily to increased sales of OTC CLARITIN and sun care products.

Animal Health sales increased 12 percent to $232 million, reflecting growth across most geographic areas, led by the companion animal, poultry and swine product lines and the positive impact of foreign currency exchange rates.

Schering-Plough incurs substantial costs such as selling, general and administrative costs that are not reflected in “Equity income from cholesterol joint venture” and are borne by the overall cost structure of Schering-Plough. As a result, Schering-Plough’s gross margin and ratios of selling, general and administrative (SG&A) expenses and R&D expenses as a percentage of sales do not reflect the benefit of the impact of the cholesterol joint venture’s operating results.

Schering-Plough’s gross margin was 68.5 percent for the 2007 first quarter as compared to 65.0 percent in the 2006 period. This improvement was due to improved product mix and cost savings from the 2006 manufacturing streamlining activities. Additionally, the company is achieving greater production efficiencies and process improvements through its “Right First Time” initiative.

SG&A expenses were $1.2 billion in the first quarter of 2007, up 12 percent versus $1.1 billion in the prior year period. SG&A in the first quarter of 2007 reflected field support for new launches, higher promotional spending and ongoing investments in emerging markets.

Research and development spending for the 2007 first quarter increased to $707 million compared to $481 million in the first quarter of 2006. Included in R&D spending in the first quarter of 2007 was $96 million related to upfront payments made for three licensing transactions that closed in the first quarter (Anacor, ALK-Abelló and Valeant/Metabasis). The increase in R&D expenses was also due to higher spending for clinical trials and related activities, and investments to build greater breadth and capacity to support Schering-Plough’s progressing pipeline.

Recent Developments

The company also offered the following summary of recent significant developments, including:

	•		Entered into an exclusive, worldwide agreement for the development and commercialization of AN2690, a topical antifungal therapy, with Anacor Pharmaceuticals, a privately held pharmaceutical company.

(Announced March 24)

	•		Announced with Centocor, Inc. that the Committee for Medicinal Products for Human Use of the European Medicines Agency issued a positive opinion recommending the approval of REMICADE (infliximab) for the treatment of severe, active Crohn’s disease in pediatric patients aged 6 to 17 years, who have not responded to conventional therapy or who are intolerant to, or have contraindications for, such therapies.
