Covance
Major Pharmaceutical Company Makes Multi-Year Commitment To Covance’s Early Development Segment
Strategic Arrangement Guaranteed to $45 Million Level
Princeton, New Jersey, March 22, 2004 — Covance Inc. (NYSE: CVD), a leading provider of drug development services, announced today that it has entered into a multi-year agreement with a major pharmaceutical company to provide early development services in a dedicated portion of their Madison, Wisconsin facility. This agreement has a guaranteed value of at least $45 million over the next three years.

"The changing dynamics in the pharmaceutical and biotechnology industries have provided us with more strategic market opportunities. As the number of new drug leads continues to grow, our clients are increasingly interested in securing dedicated resources for early development services," said Joe Herring, President and Chief Operating Officer.

This agreement introduces a pioneering approach for Covance in managing nonclinical safety studies on behalf of our clients. As part of the Madison expansion completed in 2002, Covance built flexible capacity that could be quickly converted into dedicated space. This capacity will now be dedicated to this pharmaceutical client's studies and jointly managed onsite by Covance and client staff. Covance is able to provide this client with a full range of toxicology services including regulatory toxicology, safety pharmacology, infusion, and reproductive and development studies. The relationship has the potential to include other Covance services such as bioanalysis, metabolism, and clinical pharmacology as well as toxicology services.

"This strategic agreement is a result of a long-term relationship between our two companies," said Wendel Barr, Group President of Early Development North America. "Over the years, we have worked closely with this client to better understand their needs and customize solutions that best meet those needs. Our strengths in process excellence, customer satisfaction, and our ability to provide near-real-time data through our StudyTracker® system have been instrumental in building a relationship that led to this strategic agreement."

Covance, with headquarters in Princeton, New Jersey, is one of the world's largest and most comprehensive drug development services companies with 2003 net revenues of $940 million, global operations in 18 countries, and approximately 6,500 employees worldwide.
