COVANCE NAMED MORTARA CERTIFIED PARTNER FOR ECG COMPLIANCE WITH FDA'S NEW DIGITAL STANDARD

Princeton, NJ, January 5, 2006 — Covance Inc. (NYSE: CVD) today announced that its global Cardiac Safety Services unit has achieved Mortara Certified Partner status for compliance with the digital electrocardiograph (ECG) standard now required by the U.S. Food and Drug Administration (FDA). This certifies that all ECG data Covance transmits to its biopharmaceutical sponsors is compatible with the FDA's new digital requirements, per the regulatory body's recent agreement with Mortara and its E-Scribe ECG Warehouse.

"With the increasing demand for ECG readings driven by ICH E-14 QT Guidance, it's imperative to have an efficient, accurate and flexible means of capturing, reading and submitting regulatory-ready cardiac safety data. The E-Scribe ECG Warehouse provides a key piece of the process," said Atul Minocha, General Manager of Covance's Cardiac Safety Services unit. "Covance's global biopharmaceutical clients may now leverage our proven operational processes, our leading-edge Digitography™ and Algorithm-assisted ECG Annotation technologies, as well as our renowned team of cardiologists to deliver timely, accurate, and standard data submissions directly to the FDA."

"In order for the E-Scribe ECG Warehouse to fulfill its promise, it's essential that we have the support of the industry's leading ECG Core Labs," said Justin Mortara, Vice President of Mortara Instrument. "We are pleased that Covance Cardiac Safety Services, one of the premier ECG labs, is one of our founding partners in this initiative."

The E-Scribe ECG Warehouse, developed by Mortara in collaboration with the FDA, is the repository into which all annotated ECG datasets will be uploaded for regulatory review. In order to be uploaded into the warehouse, all annotated ECGs must pass through a validation step within the E-Scribe ECG Warehouse system that checks for adherence to the HL7 XML standard. FDA reviewers will use Mortara's data warehouse system to process ECG data received from sponsors in support of new drug applications (NDAs).
