PRESS RELEASE: Merck Wins Product Liability Case in Florida Circuit Court

Merck Wins Product Liability Case in Florida Circuit Court

WHITEHOUSE STATION, N.J., Oct.  5, 2007 - Merck & Co., Inc. said today that the jury in the product liability case of Kozic v. Merck found in favor of Merck, rejecting a claim that the Company was liable for plaintiff Refik Kozic's heart attack.  Mr. Kozic alleged that he used VIOXX® for approximately nine weeks before suffering his heart attack in April 2001 at 50.

"We believe the evidence showed that Merck acted responsibly and that VIOXX was not the cause of Mr. Kozic's heart attack," said Mike Brock of Rushton, Stakely, Johnston & Garrett, P.A., based in Montgomery, Ala., outside counsel for Merck.  "We believe that Mr. Kozic's longstanding cardiovascular disease caused his heart attack."

The evidence showed that Mr. Kozic had significant atherosclerosis and coronary artery disease in the vessels that supply blood to the heart, including the vessel where the heart attack actually occurred.  Mr. Kozic had high cholesterol and other risk factors that contributed to the progression of his disease over a long period of time.

Florida Circuit Court Judge William P. Levens presided over the case.  This was the first VIOXX case in Florida to go to trial.

In addition to Mr. Brock, Merck was represented by Patricia E. Lowry and John B.T. Murray of Squire, Sanders & Dempsey LLP based in West Palm Beach, Fla.; and Eva Esber of Williams & Connolly LLP based in Washington, D.C.
