MALVERN, Pa., Feb. 8 Safety of patients treated withMyobloc(R) (Botulinum Toxin Type B) Injectable Solution has always been ofprimary importance for Solstice Neurosciences, Inc. ("Solstice"). We supporteducation and training of physicians in a number of ways regarding the properuse of this product as outlined in the prescribing information.

We maintain a rigorous and routine process for monitoring and reportingany adverse events to regulatory authorities in compliance with all applicableregulations.

Manufacturers of botulinum toxin products have recently submitted safetyinformation to the FDA. In its review of this information and other availabledata, the Agency's posting of this Early Communication "does not mean that FDAhas concluded there is a causal relationship between the drug products and theemerging safety issue."

Solstice supports the FDA review of botulinum toxins and remains committedto providing FDA with any additional information needed.
