Mr. Rodek's Experience Will Aid Accelrys in Realizing its Scientific Business Intelligence Vision

SAN DIEGO -- Accelrys, Inc. (NASDAQ:ACCL), a leading provider of scientific business intelligence solutions, announced today the appointment of Jeffrey Rodek to its Board of Directors.

Most recently Mr. Rodek served as the Executive Chairman of the Board of Directors of Hyperion Solutions Corporation, the global leader in business performance management software, until its acquisition by Oracle Corporation earlier this year. From 1999 through 2004, Mr. Rodek served as Hyperion's Chairman and Chief Executive Officer.

Prior to joining Hyperion, Mr. Rodek served as President and Chief Operating Officer of Ingram Micro, the world's largest wholesale provider of technology solutions, products and services.

He is a recognized expert and speaker on corporate performance, governance and leadership. He has been quoted in the Wall Street Journal, Business Week and Forbes, along with numerous technology trade publications.
