3. Alliance Agreement

In June 2010, the Company entered into a Strategic Alliance Agreement (the “Alliance Agreement”) with Siemens AG (“Siemens”), pursuant to which (1) the Company granted Siemens certain distribution rights to our CyberKnife Systems, (2) Siemens agreed to incorporate certain Accuray technology into certain of its linear accelerator (“linac”) products, and (3) the Company created a research and development relationship with Siemens for the pursuit and implementation of other potential collaboration opportunities. Siemens terminated the Alliance Agreement effective December 23, 2011, thereby terminating the elements described in clauses (2) and (3) above. On December 26, 2011, Siemens and the Company entered into a distribution agreement pursuant to which Siemens has the right to distribute both CyberKnife and TomoTherapy Systems. The term of this agreement ends in March 2013. Sales to date under the Siemens Alliance Agreement and subsequent distribution agreement with Accuray have not been material.

In April 2012, Siemens and Varian Medical Systems, Inc. (“Varian”) announced that they had entered into a strategic global partnership involving mutual marketing and representation of products for imaging and treatment in the global radiation oncology business, the development of software interfaces between Siemens and Varian treatment systems and potential joint development of new products. Given this announcement, the Company anticipates that Siemens will distribute few, if any, CyberKnife or TomoTherapy Systems during the remaining term of its distribution agreement.
