Geron Announces John Walker Resigns as Director

Geron Corporation (Nasdaq:GERN) today announced that John P. Walker has resigned from the Board of Directors. Mr. Walker served as a Director of the company since 1997 and was Chair of the Audit Committee.

"It has been my pleasure to serve on the Board of Directors of Geron over the last 12 years,” said Mr. Walker. "During that time I have had the privilege of being associated with a team that does groundbreaking science and is a lead force in creating the field of regenerative medicine. The clearance, by the FDA, of the company's IND for spinal cord injury is a regulatory milestone and marks the beginning of a new modality of stem cell therapy. I have accepted a position to head another company, following the closing of the Novacea and Transcept merger, which shall be announced shortly, and must in that context resign as a Geron Director.”

"We would like to thank John for his long tenure and considerable contributions to Geron during the years he served on the Board and in his capacity as Chair of the Audit Committee,” said Thomas B. Okarma, Geron’s president and chief executive officer. "We congratulate him on his new position.”
