February 16, 2003 by Jeff Shepard

Catalytica Energy Systems Inc. (Mountain View, CA) announced that Dennis Riebe will retire from his position as chief financial officer at the end of the first quarter. The company has named Robert Zack, currently vice president of finance and controller, to succeed Riebe upon his retirement. Zack will assume the position of chief financial officer effective April 1, 2003.

Riebe stated, "I am a firm believer in the commercial opportunities that lie ahead for Catalytica Energy Systems. The business has evolved through the startup phase as a public company and is gaining new momentum under our recently named President and CEO Mike Murry. This period offers an opportune time to transition the office of the CFO, and allow me to pursue my retirement interests. I am very proud of the work we have done to launch Catalytica Energy Systems as a public company and I intend to support the team in any way as it continues to advance its product offerings in the commercial market."
