As noted previously on the Current Report on Form 8-K of Accuray Incorporated (“Accuray”) dated March 6, 2011 (filed March 7, 2011), Accuray entered into an Agreement and Plan of Merger (the “Merger Agreement”), dated March 6, 2011, with TomoTherapy Incorporated, a Wisconsin corporation (“TomoTherapy”), and Jaguar Acquisition, Inc., a Wisconsin corporation and wholly owned subsidiary of Accuray (“Merger Sub”).  Pursuant to the Merger Agreement, and subject to the satisfaction or waiver of certain closing conditions, Merger Sub will merge with and into TomoTherapy, with TomoTherapy surviving as a wholly owned subsidiary of Accuray (the “Merger”).


On March 29, 2011, Accuray made a presentation to financial analysts and investors concerning the Merger.  The investor presentation delivered during such meeting is furnished herewith as Exhibit 99.1.


The information contained in, or incorporated into, this Item 7.01 and Item 8.01, including Exhibit 99.1 attached hereto, is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference into any registration statement or other filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference to such filing.


Forward Looking Statements


This Current Report on Form 8-K, including the Exhibit hereto, may contain certain forward-looking statements that involve risks and uncertainties, including uncertainties associated with the medical device industry and the transaction between Accuray and TomoTherapy.  Except for the historical information contained herein, the matters set forth in this Current Report on Form 8-K and the Exhibit hereto, including the expected structure and timetable for the transaction between Accuray and TomoTherapy, the transaction’s anticipated strategic and financial benefits, financial prospects and guidance, expectations regarding Accuray’s and TomoTherapy’s ongoing operations, employees, sales, product development and commercialization, synergies and economies of scale following the transaction, are forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995.  Forward-looking statements speak only as of the date the statements are made and are based on information available at the time those statements are made and/or managements’ good faith belief as of that time with respect to future events.  You should not put undue reliance on any forward-looking statements.  Important factors that could cause actual performance and results to differ materially from the forward-looking statements we make include:  the satisfaction of closing conditions for the transaction between Accuray and TomoTherapy, including clearance under the Hart-Scott-Rodino Antitrust Improvements Act; market conditions; the effect of the announcement of the transaction on Accuray’s and TomoTherapy’s respective businesses; the impact of any failure to complete the transaction; the risk that Accuray and TomoTherapy will not realize the anticipated benefits of the transaction; the potential inability to successfully operate or integrate TomoTherapy’s business; general industry and economic conditions; and other factors beyond the companies’ control and the risk factors and other cautionary statements described in Accuray’s and TomoTherapy’s filings with the SEC.  Please refer to the Risk Factors section of Accuray’s Quarterly Report on Form 10-Q for the fiscal quarter ended December 31, 2010, and the Risk Factors set forth in TomoTherapy’s Annual Report on Form 10-K for the fiscal year ended December 31, 2010, for a further list and description of additional business risks, uncertainties, and other factors that may affect these statements.  Neither Accuray nor TomoTherapy intends to update these statements and undertakes no duty to any person to provide any such update under any circumstance.
