Dear Shig,

Accuray Incorporated (the “Company”) is pleased to extend this Offer of Employment and invite you to join the Company in the position of VP, Finance & Chief Accounting Officer. Accuray Incorporated, the premier radiation oncology company, is committed to building an enthusiastic and talented team. We believe your abilities and experience would be a valuable asset to the Company. The effective date of your employment will be September 5, 2017 (“Start Date”), and you will be reporting directly to Kevin Waters, SVP, Chief Financial Officer. This Offer of Employment is contingent upon the successful completion of a reference check and background check, as previously agreed to in your application and release.

The terms of this Offer of Employment are as follows:

1.Compensation: As a full-time, regular, exempt employee, you will receive an annual salary of $325,000 (“Base Salary”), paid in accordance with the Company’s regular payroll practices and subject to applicable withholdings. Employee salaries are currently paid on a bi-weekly payroll schedule, every other Friday.  The Company reserves the right to change your compensation, hours, duties and benefits as it deems necessary.

2.Corporate Bonus: In your role as VP, Finance & Chief Accounting Officer, you will be eligible to participate in the Company Bonus Plan with a total Target Bonus Opportunity of thirty five percent (35%) of your Base Salary. For FY18 only, your bonus will be guaranteed to be at least one hundred percent (100%) and shall not be pro-rated based on your start date or adjusted down for failure to meet corporate objectives under the Company Bonus Plan or Performance Bonus Plan.  Bonuses are typically paid on an annual basis after the fiscal year close and are based on the achievement of specific corporate and/or individual performance goals. Bonuses are considered variable pay and are subject to all applicable taxes and withholdings.

3.Restricted Stock Units:  As a material inducement to you joining Accuray Incorporated, we will recommend to the Compensation Committee of the Board of Directors that you be granted one hundred thousand (100,000) restricted stock units (“RSUs”) under the Accuray 2016 Equity Incentive Plan. The grant of the RSUs is subject to and conditioned on approval of the grant and its terms by the Compensation Committee, and will be made as soon as practicable following your Start Date in accordance with the Company’s equity grant guidelines and policies.  Subject to your continued service as an employee through each applicable vesting date, twenty-five percent (25%) of the RSUs shall vest on the first anniversary of the RSUs grant date and an additional twenty-five percent (25%) of the RSUs shall vest on each of the second, third and fourth anniversaries of the grant date.

The RSUs will be subject to the terms and conditions of either the 2016 Equity Incentive Plan and a restricted stock unit grant agreement, an inducement plan, or an inducement award agreement and any related agreements, which you will be required to sign as a condition to receiving the RSUs (the “RSU Agreement”). RSUs that vest in accordance with the RSU Agreement will be settled in whole shares of our common stock as soon as practicable after the applicable vesting date, but in no event later than 60 days after such vesting date.

·20 days of accrued paid time off per year;

·Participation in the Company’s Flexible Spending Plan through which you may make pretax payments for childcare or medical premium reimbursement accounts;

Change in Control Benefit: In an effort to provide some additional piece of mind, Accuray will present a request to the Compensation Committee of the Board of Directors, for certain acceleration and compensation benefits, in the event you are terminated within three months prior and twelve months following a “Change in Control” of the Company.

The specifics and the existence of these programs may change from time to time.

5.At-Will Employment:  You should be aware that your employment with the Company is for no specified period and constitutes “at-will” employment.  As a result, you are free to terminate your employment at any time, for any reason or for no reason.  Similarly, the Company is free to terminate your employment at any time, for any reason or for no reason.  In the event of termination of your employment, you will not be entitled to any payments, benefits, damages, awards, or compensation other than as may otherwise be available in accordance with the Company’s established employee plans and policies at the time of termination.

6.Immigration Laws:  For purposes of federal immigration laws, you will be required to provide to the Company documentary evidence of your identity and eligibility for employment in the United States.  Such documentation must be provided within three days of your employment, or your employment relationship with the Company will be terminated.

7.New Hire Orientation:  You must attend a new hire orientation session on a date in September to be specified closer to your Start Date.  During this session, many items will be discussed including your benefits.  One to two weeks prior to your Start Date you will receive new hire documents via email that will need to be completed.  We would also like to ask that you bring your I-9 documents to this session.

8.Confidentiality Agreement:  As a condition of your employment, you will be required to complete, sign, return and abide by the Company’s Employee Invention Assignment and Confidentiality Agreement.
