This Program shall remain in effect until it is revised or rescinded by further action of the Board.  This Program may be amended, modified or terminated by the Board at any time in its sole discretion.  The terms and conditions of this Program shall supersede any prior cash and/or equity compensation arrangements for service as a member of the Board between the Company and any of its Non-Employee Directors.  No Non-Employee Director shall have any rights hereunder, except with respect to stock options granted pursuant to the Program.  This Program shall become effective on the Effective Date.

II.    Equity Compensation 
Non-Employee Directors shall be granted the equity awards described below.  The awards described below shall be granted under and shall be subject to the terms and provisions of the Company’s 2018 Incentive Award Plan or any other applicable Company equity incentive plan then-maintained by the Company (the “Equity Plan”) and shall be granted subject to award 











agreements, including attached exhibits, in substantially the form previously approved by the Board.  All applicable terms of the Equity Plan apply to this Program as if fully set forth herein, and all grants of stock options hereby are subject in all respects to the terms of the Equity Plan and the applicable award agreement.  For the avoidance of doubt, the share numbers in Sections II(A) and II(B) shall be subject to adjustment as provided in the Equity Plan, and in connection with any stock dividend, stock split, reverse stock split or other similar event affecting the Company’s common stock that is effected prior to the Effective Date.
A.    Initial Awards.  Each Non-Employee Director who is initially elected or appointed to the Board after the Effective Date shall receive an option to purchase 31,380 shares of the Company’s common stock on the date of such initial election or appointment. The awards described in this Section II(A) shall be referred to as “Initial Awards.”  No Non-Employee Director shall be granted more than one Initial Award. 
B.    Subsequent Awards.  A Non-Employee Director who (i) has been serving as a Non-Employee Director on the Board for at least six months as of the date of any annual meeting of the Company’s stockholders after the Effective Date and (ii) will continue to serve as a Non-Employee Director immediately following such meeting, shall be automatically granted an option to purchase 15,690 shares of the Company’s common stock on the date of such annual meeting.  The awards described in this Section II(B) shall be referred to as “Subsequent Awards.”  For the avoidance of doubt, a Non-Employee Director elected for the first time to the Board at an annual meeting of the Company’s stockholders shall only receive an Initial Award in connection with such election, and shall not receive any Subsequent Award on the date of such meeting as well.  
        
C.    Termination of Employment of Employee Directors.  Members of the Board who are employees of the Company or any parent or subsidiary of the Company who subsequently terminate their employment with the Company and any parent or subsidiary of the Company and remain on the Board will not receive an Initial Award pursuant to Section II(A) above, but to the extent that they are otherwise entitled, will receive, after termination of employment with the Company and any parent or subsidiary of the Company, Subsequent Awards as described in Section II(B) above.  
D.    Terms of Awards Granted to Non-Employee Directors
1.      Exercise Price.  The per share exercise price of each option granted to a Non-Employee Director shall equal the Fair Market Value (as defined in the Equity Plan) of a share of the Company’s common stock on the date the option is granted. 
2.    Vesting.  Each Initial Award shall vest and become exercisable in thirty-six (36) substantially equal monthly installments following the date of grant, such that the Initial Award shall be fully vested on the third anniversary of the date of grant, subject to the Non-Employee Director continuing in service as a Non-Employee Director through each such vesting date.  Each Subsequent Award shall vest and become exercisable on the earlier of the first anniversary of the date of grant or the day immediately prior to the date of the next annual meeting of the Company’s stockholders occurring after the date of grant, in either case subject to the Non-Employee Director continuing in service on the Board as a Non-Employee Director through each such vesting date.  Unless the Board otherwise determines, any portion of an Initial Award or Subsequent Award which is unvested or unexercisable at the time of a Non-Employee Director’s termination of service on the Board as a Non-Employee Director shall be immediately forfeited upon such termination of service and shall not thereafter become vested and exercisable.  All of a Non-Employee Director’s Initial Awards and Subsequent Awards shall vest in full immediately prior to the occurrence of a Change in Control (as defined in the Equity Plan), to the extent outstanding at such time.
3.    Term.  The maximum term of each stock option granted to a Non-Employee Director hereunder shall be ten (10) years from the date the option is granted.
