"Richard brings a very unique skill set to a company with a very unique set of capabilities," stated J. Michael French, President and Chief Executive Officer. "As we looked to expand our R&D leadership team, we sought someone who we believed would apply a unique viewpoint to our research team and drug discovery platform and be capable of applying that vision to the multidimensional challenge of drug discovery and development. Richard is exactly that kind of leader. I look forward to working with Richard and watching our progress under his mentorship and guidance."

Mr. French continued, "I want to thank Barry for leading the scientific efforts of the Company over the past two and a half years - he's done a tremendous job. I look forward to his continued contributions in supporting the new R&D leadership team as well as heading our SAB. I also want to thank Pete for his efforts over the past two years in what can only be described as a bleak financing environment. His commitment to the Company never wavered. We look forward to having Alan Dunton join the team as our Chief Medical Officer. Alan brings a significant set of experiences and expertise which will serve the Company well as we consider our existing and future clinical trial efforts. Finally, I want to welcome Phil Ranker back to the Company. Phil brings a tremendous breadth of expertise to our finance team, having served in a variety of finance positions in both biotech and big pharma.
