ITEM 5.    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. Product Lines

         On March 21, 2000, the Company announced in a press release that it had
agreed to acquire from NMT Medical, Inc. the Selector(R) Ultrasonic Aspirator,
Ruggles(TM) Surgical Instrumentation and Spembly Medical Cryosurgery product
lines, including certain assets and liabilities, for an acquisition price of
$12.0 million cash. The assets to be acquired include a manufacturing, packaging
and distribution facility located in Andover, England. The consummation of the
transaction is subject to customary conditions.
