Applied Biosystems Promotes Mark Stevenson to President and Chief Operating Officer

FOSTER CITY, Calif.–Dec. 19, 2007–Applera Corporation today named Mark P. Stevenson president and chief operating officer of its Applied Biosystems Group (NYSE:ABI) and a senior vice president of the corporation. Mr. Stevenson has been executive vice president of Applied Biosystems since July 2007 and has been with the company since 1998. “This decision completes the Applied Biosystems management transition that began more than a year ago,” said Tony L. White, chairman, president, and CEO of Applera, who has served as interim president of Applied Biosystems since October 2006. “Mark is a strong leader and strategic thinker with tremendous knowledge of Applied Biosystems and the life science tools industry. His experience in a variety of sales, marketing and general management roles in Europe, Japan, and the United States and his understanding of the market make him particularly qualified to manage all day-to-day operations at Applied Biosystems.” Mr. Stevenson joined Applied Biosystems Europe in 1998 after previous positions with other life science companies. He has contributed to the growth of Applied Biosystems in diverse roles including: vice president of molecular biology sales in Europe; president and general manager of Applied Biosystems Japan; founding president of the Applied Markets Division, and president of the Molecular and Cellular Biology (MCB) Division. During his tenure as MCB Division President, he achieved revenue and profit growth from more mature businesses while investing in new growth engines such as molecular biology consumables and next generation sequencing. After his appointment in July 2007 to executive vice president, his responsibilities expanded to include oversight of Europe, Japan, Global Services, and the Applied Markets business. In his new role he now adds the Proteomics and Small Molecule (PSM) Division and the Asia Pacific Region to his portfolio. “Applied Biosystems has an excellent reputation of providing our customers with innovative tools, a strong history of growth and profitability, and a talented and hardworking group of employees,” said Mr. Stevenson. “Applied Biosystems has exciting times ahead as we pursue multiple growth vectors across technologies, applications, and geographies and improvements in the operational performance of the business.” About Applera Corporation and Applied Biosystems Applera Corporation consists of two operating groups.
