Effective September 4, 2009, the Board of Directors of Accuray Incorporated filled two vacant seats with the appointment of Mr. Louis J. Lavigne, Jr. and Mr. Dennis L. Winger as members of the company’s Board of Directors. Mr. Lavigne and Mr. Winger are independent directors within the meaning of the rules of the Nasdaq Stock Market. Mr. Lavigne and Mr. Winger will serve as Class II members of the Board of Directors and will stand for election at the company’s 2011 annual meeting of stockholders.

Mr. Lavigne is currently an independent consultant specializing in the areas of corporate finance, accounting and strategy.

It is expected that Mr. Lavigne will serve on the Audit Committee of the Board of Directors and Mr. Winger will serve on the Compensation Committee of the Board of the Directors. Either one or both of them may also serve on the Nominating and Corporate Governance Committee of the Board of Directors.

Mr. Lavigne and Mr. Winger will receive the same cash and equity compensation for their service on the Board of Directors and board committees, as is currently paid to all non-employee members of Accuray’s Board of Directors. A description of the compensation for non–employee directors is in Accuray’s proxy statement for the 2008 annual meeting of stockholders and was unchanged in fiscal 2009.
