IMPAX Mourns The Death Of Dr. Charles Hsiao, Co-Founder And Chairman

September 15, 2008

HAYWARD, Calif. (September 15, 2008) – IMPAX Laboratories, Inc. sadly reports the recent death of Charles Hsiao, Ph.D., its long-time Chairman. Dr. Hsiao was a co-founder of the Company’s predecessor, Impax Pharmaceuticals, Inc., in 1995, and served as the Company’s Co-Chief Executive Officer from 1999 to 2003.  Long regarded as a leader in the generic pharmaceutical industry, in 1986 Dr. Hsiao was one of three co-founders of IVAX Corporation, which, by 1994, when he left the Vice-Chairman position at IVAX, had become the world’s largest generic pharmaceutical company at the time. 

While Dr. Hsiao co-led IMPAX’s research and development activities for a number of years, on January 1, 2004 he transitioned from the Company’s day-to-day product development activities and took charge of long-term exploratory research activities with a newly established laboratory located at Pleasanton, California.  His creative approaches and intellectual curiosities have been instilled in a team of talented scientists at Impax who continue to excel in formulation and drug delivery technology.

Larry Hsu, Ph.D, President and Chief Executive Officer, who co-founded IMPAX with Dr. Hsiao, said: “Charlie’s passing will be a great loss. His leadership, entrepreneurial spirit, scientific expertise and significant accomplishments were a substantial factor in the formation and growth of the Company.  As we grieve this tragic loss, Charlie’s passion for the continued success and growth of the Company will live on.”
