Compensation Program for Non-Employee Directors

1.Non-employee directors (“Outside Directors”) will receive the cash retainers, paid quarterly in arrears, for their service on the Board of Directors (the “Board”) and its committees as provided in Exhibit A, which may be modified by the Board in its discretion.

1.Annual Equity Award: Unless another date is approved by the Board prior to the regular meeting of the Company’s stockholders (the “Annual Stockholder Meeting”), upon the conclusion of each Annual Stockholder Meeting beginning in calendar year 2021 (the “Annual Grant Date”), each Outside Director who continues to serve as a member of the Board thereafter (including a director elected or appointed at such meeting) will automatically be granted restricted stock units (“RSUs”) under the Company’s 2018 Equity Incentive Plan (the “Plan”) with an annual target value as provided in Exhibit A, which may be modified by the Board in its discretion (the “Annual Equity Target Value”). Subject to the Outside Director’s continuing service, each such RSU award will vest in full on the earlier of the one-year anniversary of the Annual Grant Date or the date of the Annual Stockholder Meeting held in the year following the Annual Grant Date.

2.Pro-Rated Annual Equity Award: On the date an Outside Director is first elected or appointed to the Board, the Outside Director will automatically be granted a pro-rated annual equity award consisting of RSUs under the Plan. Such pro-rated annual equity award will have an aggregate target value equal to (i) the Annual Equity Target Value, multiplied by (ii) a fraction, the numerator of which is the number of whole months remaining until the one-year anniversary of the most recent regular annual meeting of stockholders and the denominator of which is 12 (the “Pro-Rated Equity Target Value”). Subject to the Outside Director’s continuing service, each such RSU award will vest in full on the earlier of the one-year anniversary of the date of grant or on the date of the Annual Stockholder Meeting following the date of grant. For avoidance of doubt, an Outside Director who is first elected or appointed to the Board on the date of an Annual Stockholder Meeting will receive the full annual equity award described in section B1 above, without any pro-ration.
