We feel good about our continuing momentum and direction for the year."

UTI-Stat® (ProAntinox®) Study Published

Also in the quarter, the Company announced the publication of an independent clinical study showing that the Company's UTI-Stat® (ProAntinox®) product demonstrated effectiveness in significantly reducing the anticipated incidence of recurrent urinary tract infections (UTI) and significantly improved quality of life in those with a history of UTI. The study was conducted by Dr. Aaron E. Katz, Professor of Clinical Urology at Columbia University's College of Physicians and Surgeons and published by the peer-reviewed journal Urology, the official journal of the International Society of Urology. The results of the study were consistent with those in a 2008 study of UTI-Stat® among nursing home residents.

UTI-Stat® (ProAntinox®) is also available over-the-counter as Cystex® Cranberry. The study can be found at: http://www.goldjournal.net/article/S0090-4295(10)00183-4/abstract.
