Echelon Makes Announcement Regarding CEO

(San Jose, CA – November 4, 2009) – Echelon Corporation (NASDAQ: ELON) announced today that M. Kenneth Oshman, the company’s Chairman and Chief Executive Officer, has been diagnosed with lung cancer. Indications are that the cancer is both treatable and curable. Mr. Oshman is working with medical advisors to assess the appropriate treatment program going forward and plans to begin treatment as soon as possible. Mr. Oshman has decided to step down as CEO of Echelon to insure that there is dedicated full-time leadership at the company and to provide him with time to focus on his recovery. Mr. Oshman intends to remain an active Executive Chairman of the company and intends to continue to be involved with Echelon as much as possible.

The company also announced that its Board of Directors has appointed Robert R. Maxfield, a current member of the Board, to serve as Chief Executive Officer effective November 5, 2009, while the company launches a search for a new CEO. The Board feels enormously fortunate that Mr. Maxfield has agreed to serve in this capacity. Mr. Maxfield provided outstanding leadership to the company during 2008 while the company carried out a search for a Senior Vice President, Products; he has served as an advisor to Mr. Oshman since that time. He is intimately familiar with the company, its products and its business, and he will be able to be immediately effective in this role.

Mr. Maxfield will continue to serve on the company’s Board of Directors; however, he will no longer serve on the Compensation Committee. In addition, the Board has appointed current director Betsy Rafael to replace Mr. Maxfield on the Compensation Committee.
