Other Events. Merck Litigation On March 20, 2000, Integra LifeSciences Holdings Corporation, a Delaware corporation (the "Company"), announced in a press release that on March 17, 2000 a federal jury sitting in the case Integra LifeSciences (and certain affiliates) and The Burnham Institute vs. Merck KGaA (United States District Court for the Southern District of California) returned a unanimous verdict for the plaintiffs, found that Merck KGaA had willfully infringed and induced the infringement of Integra's patents and awarded $15,000,000 in damages. The damage award may be adjusted by the court. The lawsuit, which was filed in 1996, alleged that Merck KGaA and a non-profit research institution under contract from Merck KGaA had infringed various United States patents held by The Burnham Institute of San Diego that have been licensed to the Company. Those patents include No. 4,792,525, No. 4,879,237, No. 5,659,997 and No. 4,789,734, each in various ways relating to technology involving peptides containing an arginine-glycine-aspartic acid (RGD) sequence or related cell surface receptors. The Company expects that post-trial motions will be filed, and that Merck KGaA will appeal various decisions of the court and request a new trial, a reduction in damages, or a judgment as a matter of law notwithstanding the verdict. The Company cannot accurately predict the ultimate resolution of this matter and has not reflected the verdict in its financial statements. Agreements to Acquire Certain NMT Medical, Inc.
