otherwise payable retainer(s) by a fraction, the numerator of which is the number of days during which the Non-Employee Independent Director serves as a Non-Employee Independent Director or in the applicable positions described in Section 1(b) during the applicable calendar quarter and the denominator of which is the number of days in the applicable calendar quarter.

2.Equity Compensation. Non-Employee Independent 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 2021 Incentive Award Plan or any other applicable Company equity incentive plan then-maintained by the Company (such plan, as may be amended from time to time, the “Equity Plan”) and shall be granted subject to the execution and delivery of award agreements, including attached exhibits, in substantially the forms previously approved by the Board. All applicable terms of the Equity Plan apply to this Policy as if fully set forth herein, and all equity grants hereunder are subject in all respects to the terms of the Equity Plan.

(a)Annual Awards. Each Non-Employee Independent Director who (i) serves on the Board as of the date of any annual meeting of the Company’s stockholders (an “Annual Meeting”) and (ii) will continue to serve as a Non-Employee Independent Director immediately following such Annual Meeting, shall be automatically granted, on the date of such Annual Meeting, an award of restricted stock units that has an aggregate fair value on the date of grant of $170,000 (as determined in accordance with ASC 718 and subject to adjustment as provided in the Equity Plan). The awards described in this Section 2(a) shall be referred to as the “Annual Awards.” For the avoidance of doubt, a Non-Employee Independent Director elected for the first time to the Board at an Annual Meeting shall receive only an Annual Award in connection with such election, and shall not receive any Initial Award on the date of such Annual Meeting as well.

(b)Initial Awards. Except as otherwise determined by the Board, each Non-Employee Independent Director who is initially elected or appointed to the on any date other than the date of an Annual Meeting shall be automatically granted, on the date of such Non-Employee Independent Director’s initial election or appointment (such Non-Employee Independent Director’s “Start Date”), an award of restricted stock units that has an aggregate fair value on such Non-Employee Independent Director’s Start Date equal to the product of (i) $170,000 (as determined in accordance with ASC 718) and (ii) a fraction, the numerator of which is (x) 365 minus (y) the number of days in the period beginning on the date of the Annual Meeting immediately preceding such Non-Employee Independent Director’s Start Date and ending on such Non-Employee Independent Director’s Start Date and the denominator of which is 365 (with the number of shares of common stock underlying each such award subject to adjustment as provided in the Equity Plan). The awards described in this Section 2(b) shall be referred to as “Initial Awards.” For the avoidance of doubt, no Non-Employee Independent Director shall be granted more than one Initial Award.

(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 2(b) above, but to the extent that they are otherwise eligible, will be eligible to receive, after termination from employment with the Company and any parent or subsidiary of the Company, Annual Awards as described in Section 2(a) above.

(d)Vesting of Awards Granted to Non-Employee Independent Directors. Each Annual Award and Initial Award shall vest on the first anniversary of the date of grant, subject to the Non-Employee Independent Director continuing in service on the Board through the applicable vesting date. No portion of an Annual Award or Initial Award that is unvested at

the time of a Non-Employee Independent Director’s termination of service on the Board shall become vested thereafter. All of a Non-Employee Independent Director’s Annual Awards and Initial 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.Review of Policy. The Compensation Committee shall review this Policy periodically and may recommend any modifications to the Board. The Board will determine any changes to be made to this Policy based on the Compensation Committee's recommendations.
