Network Appliance Named a "Best Company to Work For" By Fortune Magazine for Third Consecutive Year

Sunnyvale, Calif. - January 11, 2005 - Network Appliance, Inc. (NASDAQ: NTAP), the leader in advanced network storage solutions, today was named by FORTUNE magazine as one of the "100 Best Companies to Work For" for the third consecutive year. This year, NetApp ranked at number 24, up from number 48 last year, reflecting the company's specific emphasis on attracting and retaining the best talent in the industry and continuing to demonstrate the values of what NetApp CEO Dan Warmenhoven calls a "model company." The elite and prestigious FORTUNE listing is largely determined by employee feedback.

"It is a tremendous accomplishment to be recognized year after year as one of the nation's 'Best Companies to Work For' by FORTUNE magazine, and I am pleased that our ranking improved significantly this year," said Dan Warmenhoven, CEO of Network Appliance. "Our focus has always been and will continue to be on fostering and maintaining a unique and stimulating work environment that encourages creativity, innovation, collaboration, and risk-taking for our employees. Our customers benefit from the strength and productivity of our employees as we continue to push storage innovation, customer intimacy, and operational excellence to offer the world's leading advanced data management solutions."

"At NetApp, one of our main objectives is to create and maintain a unique work environment based on open and honest communication, which is core to our values and core to building trust within our company," said Gwen McDonald, senior vice president, Human Resources. "Given that feedback from our employees helps us to earn this recognition each year, this is an especially gratifying achievement for us to receive and an important acknowledgement that we are meeting our objectives and creating a very special place to work."

FORTUNE magazine compiles and selects the "100 Best Companies to Work For" list every year from a pool of eligible U.S.-based applicants. This year, FORTUNE worked with Robert Levering and Milton Moskowitz of the Great Place to Work Institute in San Francisco, based on two criteria: an evaluation of the policies and culture of each company and the opinions of the company's employees. The latter is given more weight; two-thirds of the total score comes from employee responses to a 57-question survey, which goes to a minimum of 350 randomly selected employees from each company. It asks about things such as attitudes toward management, job satisfaction, and camaraderie within the organization. The remaining one-third of the score is based on an evaluation of each company's demographic makeup, pay and benefits programs, and culture. Companies are scored in four areas: credibility (communication to employees), respect (opportunities and benefits), fairness (compensation and diversity), and pride/camaraderie (philanthropy and celebrations).

The "100 Best Companies to Work For" list and related stories will appear in the January 24, 2005, issue of FORTUNE magazine, available on newsstands January 17 and at www.fortune.com on January 10, 2005.
