ITEM 8.01.  OTHER EVENTS.

On November 7, 2005, Integra LifeSciences Holdings Corporation ("Integra"),
voluntarily withdrew, and within 48 hours of such date, will refile, its
Notification and Report Form under the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended, relating to the pending acquisition of the assets of
the Radionics Division of Tyco Healthcare Group LP from Tyco Healthcare Group LP
and Sherwood Services, AG by Integra LifeSciences Corporation and Integra
LifeSciences (Ireland) Limited, wholly owned subsidiaries of Integra. The
refiling is a procedural step to provide the antitrust regulators with
additional time to review the information submitted by Integra and Tyco
Healthcare Group LP. This is a commonly used technique to permit further
informal discussions with the regulators.

Pursuant to the requirements of the Securities Exchange Act of 1934, as amended,
