IRIS International Elects Edward F. Voboril to Board of Directors

IRIS INTERNATIONAL, INC. (NASDAQ: IRIS), a leading manufacturer of automated in-vitro diagnostics systems and consumables for use in hospitals and commercial laboratories worldwide, announced today that Edward F. Voboril, a seasoned senior executive and director within the medical device and healthcare industry, has been elected to the Company's Board of Directors, expanding its board to eight members.

"Mr. Voboril's extensive career in the healthcare and technology sectors will be invaluable as we continue the rapid growth and extension of our core urinalysis technology platform, and as we proceed with our new diagnostics initiatives and extensive product pipeline," stated Cesar Garcia, Chairman, President and Chief Executive Officer of IRIS International.

"His career encompasses nearly 20 years experience as chairman, chief executive officer and director for mid-sized public companies, as well as not-for-profit organizations, having served on audit, nominating, compensation and corporate governance committees. His skills will complement and be an asset to our current board and we look forward to his contributions," Mr. Garcia said.

Mr. Voboril is currently Chairman of the Board of Analogic Corporation (NASDAQ: ALOG), a leading $370 million designer and manufacturer of advanced health and security systems and subsystems sold primarily to Original Equipment Manufacturers (OEMs). He has been a member of the Analogic board since 1990.

In 2008, Mr. Voboril, 65, retired as Chairman of Greatbatch, Inc. (NYSE:GB), a technology based manufacturer of medical devices and specialty power sources, where he served as Chief Executive Officer from 1990 to 2006. During his tenure at Greatbatch, he led the Company from revenues of about $30 million to $318 million in 2007 as Greatbatch evolved from a small specialty battery manufacturer to a world leader in the supply of precision components for implantable medical devices. Under his leadership, Greatbatch's growth was driven by both the development of its own proprietary technology and complementary acquisitions.

Mr. Voboril also served as Vice President and General Manager of the Biomedical Division of PPG Industries and held senior executive positions in the medical businesses of Honeywell, General Electric, Syntex and Litton Industries. In addition, from 1995 to 1998, he was President of the Health Care Industries Association (HCIA), a not-for-profit trade association and networking support organization in Western New York that provides professional services for healthcare industries and institutions.

Mr. Voboril is presently an adjunct professor of engineering and chairman of 'NUvention' at the Center for Entrepreneurship and Innovation at Northwestern University, and also serves on the manufacturing council of the United States Department of Commerce. He holds a Bachelor of Arts degree in Industrial Engineering from Northwestern University and an MBA from Harvard University where he was a Baker Scholar.
