MARLBORO, Mass.—May 22, 2006—Egenera Inc. today announced that it has been selected as a winner of the annual "Red Herring 100 North America" award by Red Herring magazine. The list of 100 private companies in North America recognizes those that play a leading role in innovating the technology business. The entire list can be viewed at www.redherring.com.

"It is an honor to be acknowledged by Red Herring as one of the top private companies in North America," said Bob Dutkowsky, chairman, president and CEO of Egenera. "Not only does this award validate Egenera's longevity and value for customers, but it recognizes the innovative people that come to work at Egenera every day. We've assembled a world-class team that truly believes in what we're building. This award is a direct result of the execution, focus and passion of the entire Egenera organization."

Egenera was founded in March 2000 by Vern Brownell, former CTO of Goldman Sachs, based on his experience running one of the world's largest and most sophisticated datacenters. An early pioneer in pivotal markets such as virtualization, blade servers and utility computing, Egenera brings its experience and depth to a rapidly growing customer list of global enterprises, service providers and federal agencies.

Vern Brownell, Egenera founder and CTO, will present the company's strategy at the exclusive Red Herring Spring 2006 CEO summit, May 23-25 in Monterey, Calif. The event will host a select group of technology entrepreneurs, investors and corporate developers who will be the first to explore this next wave of disruptive technology companies.

"With venture capital flowing again, we're seeing a lot of innovative new companies taking on the established players with disruptive technologies and innovative business plans," said Joel Dreyfuss, editor-in-chief, Red Herring. "The Red Herring 100 North America companies, among them Egenera, are pushing and breaking the boundaries of the technology business and we are excited to report on their success stories."

More Than Just Buzz
Red Herring's lists of top private companies are an important part of the magazine's tradition of identifying new and innovative technology companies and leaders. Companies including Google and eBay were spotted in their early days by Red Herring editors as some that would change the way we live and work.

After receiving more than 1,000 submissions and nominations, Red Herring's editorial staff rigorously evaluated Egenera and the other contenders through a careful analysis of financial data and subjective criteria, including quality of management, execution of strategy, and dedication to research and development. The Red Herring 100 North America companies are at the forefront of the technologies that are changing the business of technology in profound ways.

To honor the Red Herring 100 companies, Red Herring has invited their CEOs and founders to present at its Red Herring Spring 2006 conference, a forum for technology's most exciting companies, and to share their insights on the future of innovation and the entrepreneurial journey. Scheduled to take place at the Hyatt Regency Hotel in Monterey, this intimate, invitation-only conference will explore "The Pursuit of Disruption" and how it spawns unexpected opportunities, novel alliances, and great success stories.
