Amendment to Employment Agreement, dated April 3, 2023, among FTC Solar, Inc. and Sean Hunkler

The Amended Tranche 1 Options shall become vested over a four-year period as follows: (i) 25% of such Amended Tranche 1 Options will vest on the one-year anniversary of the $10 Effective Date and (ii) 1/48 of such Amended Tranche 1 Options will vest at the end of each month thereafter until the four-year anniversary of the $10 Effective Date; provided, in each case, that you are an active employee as of each such relevant vesting date. The “$10 Effective Date” shall mean the first date after which the Company’s Common Stock has (a) closed above $10 per share on both the first and last day of any ninety (90) calendar day period, (b) closed above $10 per share on both the first and last day of any sixty (60) trading day period during such 90 calendar day period and (c) closed above $10 per share on at least forty-five (45) trading days during such 60 trading day period; provided, that such date must occur either (X) within the first four (4) years from the Effective Date or (Y) between the four (4) year anniversary of the Effective Date and the seven (7) year anniversary of the Effective Date if the $21 Effective Date shall have also occurred as of such date. For clarity, if the $10 Effective Date never occurs, the Amended Tranche 1 Options will never vest and be forfeited upon your departure or the seven (7) year anniversary of the Effective Date, as applicable.

The Amended Tranche 2 Options shall become vested over a four-year period as follows: (i) 25% of such Amended Tranche 2 Options will vest on the one-year anniversary of the $21 Effective Date and (ii) 1/48 of such Amended Tranche 2 Options will vest at the end of each month thereafter until the four-year anniversary of the $21 Effective Date; provided, in each case, that you are an active employee as of each such relevant vesting date. The “$21 Effective Date” shall mean the first date after which the Company’s Common Stock has (a) closed above $21 per share on both the first and last day of any ninety (90) calendar day period, (b) closed above $21 per share on both the first and last day of any sixty (60) trading day period during such 90 calendar day period and (c) closed above $21 per share on at least forty-five (45) trading days during such 60 trading day period; provided, that such date must occur within the first seven (7) years from the Effective Date. For clarity, if the $21 Effective Date never occurs, the Amended Tranche 2 Options will never vest and be forfeited upon your departure or the seven (7) year anniversary of the Effective Date, as applicable.
