EXHIBIT A
---------
As a result of the Company's decision to defer deliveries of its Millennium
laser-based HydroKinetic system to its German distributor until completion of
the partial redesign of the system's handpiece and, due to the delay of the
Company receiving Food and Drug Administration clearance in October, 1998 to
market the Millennium domestically, for certain dental hard-tissue applications,
sales for the three months ended September 30, 1998 are expected to be
significantly lower than those reported for the comparable period in 1997.
The Company expects the net loss for the three months ended September 30,
1998 to increase significantly over that reported for the comparable period in
1997 due to reduced sales coupled with a one-time non-cash charge of
approximately $5,000,000 in connection with the acquisition of in-process
research and development efforts acquired from Laser Skin Toner, Inc., a
Missouri corporation, on July 2, 1998.
