ITEM 2. Acquisition or Disposition of Assets.

      On April 5, 2000, Integra LifeSciences Holdings Corporation, a Delaware
corporation (the "Company"), acquired 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 $12.0
million in cash. The assets acquired from NMT Medical include the lease of a
manufacturing, packaging and distribution facility located in Andover, England.

      In connection with the acquisition, the Company changed the name of its
neurosurgical device business from Integra NeuroCare to Integra NeuroSciences.
Integra NeuroSciences designs, manufactures and sells implants, instruments and
monitors used in neurosurgery and intensive care units, primarily for the
treatment of neurological trauma and surgery. Revenue of the acquired product
lines during 1999 was approximately $12.1 million.

ITEM 5. Other Events.

      On March 29, 2000, Quantum Industrial Partners LDC and SFM Investments
LLC, investment affiliates of Soros Private Equity Partners LLC, invested an
additional $5.4 million in the Company. The Soros affiliates acquired 54,000
shares of Integra Series C Convertible Preferred Stock (that are convertible
into 600,000 shares of common stock) and warrants to purchase an additional
300,000 shares of common stock at $9.00 per share. The warrants are exercisable
at any time before their expiration on December 31, 2001.

      In connection with the investment by the Soros affiliates, the Company
amended the Registration Rights Agreement dated March 29, 1999 that the parties
originally entered into in connection with the Company's sale of Series B
Convertible Preferred Stock and related warrants on March 29, 1999. The Amended
