Cambridge, MA March 30, 2004 — Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced that John F. Niblack, Ph.D., has agreed to be nominated for election to the Company's Board of Directors at the upcoming Annual Meeting of Shareholders on May 6, 2004.

Dr. Niblack directed the late-stage development and regulatory filings for top selling drugs across a broad range of diseases, including Norvasc®, Zoloft®, Zithromax®, Diflucan® and Viagra®.

"Under John Niblack's leadership, Pfizer's Global Research and Development group established a track record as one of the most innovative and successful research operations in the history of the pharmaceutical industry," said Joshua Boger, Ph.D., Chairman and Chief Executive Officer of Vertex Pharmaceuticals. "Vertex will benefit from John's experience as we seek to develop and launch breakthrough medicines for a wide range of serious diseases."
