Fredric D. Price, BioMarin's Chairman and Chief Executive Officer, said, "Strengthening our management team has been one of BioMarin's most important initiatives this year. The addition of Lou Drapeau, who brings over thirty years of senior financial management experience, will enable us to build on the valuable work that our `acting CFO', Franz Cristiani, has provided since the beginning of this year. Franz's appointment to our Board of Directors, where he will serve as chairperson of the audit committee, will be invaluable to us as the business moves forward to meet our clinical and commercial goals." Mr. Price added, "We are also pleased to welcome Elaine Heron and Vijay Samant to our Board of Directors. Their vast experience in leading large, entrepreneurial, and technology-driven life science companies will add a fresh perspective to the Board.
