REGULATION FD DISCLOSURE. On March 6, 2006, Integra LifeSciences Holdings Corporation (the "Company") held a conference call to discuss its financial results for the quarter and year ended December 31, 2005 and forward-looking financial guidance. Notice of the conference call was provided by a press release and was open to all listeners and followed by a question and answer session. During the call, the Company made the following forward-looking statements regarding the Radionics business it recent recently acquired: * The Company expects the Radionics acquisition to contribute approximately $4 million of net revenue in the first quarter of 2006 and approximately $40 million of net revenue for the full year 2006, reflecting the direct impact of the Radionics acquisition and the assumption that the Company's sales force will, in some situations, sell Radionics' CUSA EXcel ultrasonic aspiration system in lieu of the Company's existing ultrasonic aspirator products. The Company expects that this revenue will be evenly distributed throughout 2006, with a slight increase from the second quarter through the fourth quarter. * Outside of the United States, Radionics sold products predominantly through their own subsidiaries. Going forward, about half of this business will result from direct sales by the Company's subsidiaries outside of the United States. The remaining sales will be made at a 30% to 50% discount from the amount at which products will eventually be sold to hospitals. * The Company expects that of its total 2006 estimated amortization there will be $2.3 million of amortization from the Radionics acquisition. * As a result of the Radionics acquisition, the Company intends to continue to increase its field-based support in Europe, including field-based marketing and significant service and repair functions. * The Radionics business has a significant research and development activity to support both the CUSA and the other product lines. * The Company expects net interest expense for 2006 to be approximately $3.3 million. This reflects the Company's use of approximately $80 million of cash to fund the Radionics acquisition. Historically, the Company's interest income on its cash balance was roughly equal to the interest expense on its convertible debt.
