2017 Equity Incentive Plan, Form of Term Sheet for 2018 Performance-Based Stock Option Awards

The Option vests on March 15, 2021, if at all, subject to Participant continuing to be a Service Provider through such date and the achievement, as approved by the Compensation Committee of the Board, of the performance goals and parameters set forth in the Standard Terms and Conditions and Exhibit A attached thereto, provided that the Option may vest earlier pursuant to the Standard Terms and Conditions; any portion of the Option that did not become Eligible Shares (as defined in Exhibit A) on the first Approval Date, shall remain eligible for vesting on March 15, 2023, if at all, subject to Participant continuing to be a Service Provider through such date and the achievement, as approved by the Compensation Committee of the Board, of the performance goals and parameters set forth in the Standard Terms and Conditions and Exhibit A attached thereto; provided, in each case, that the Option may vest earlier pursuant to the terms of this Term Sheet and the Standard Terms and Conditions and Exhibit A attached thereto.

If Participant’s employment is terminated by the Company or any Parent, Subsidiary, or Affiliate of the Company (as applicable, the “Employer”) without Cause or by reason of Participant’s death or Disability, in each case, during the last year of a Performance Period (as defined in Exhibit A), the Option will vest as to a prorated portion, subject to Participant’s execution of
