Eligibility for payments pursuant to the Transaction Bonus Pool will be limited to holders of the Company Options that were unvested and otherwise scheduled to vest in the ordinary course after the Closing Date but on or prior to the last day of the 2026 Calculation Period and which were canceled as of Closing pursuant to Section 2.5(a)(i) (the

If an Early Election is made, then (x) any portion of the 2026 Performance Amount paid in cash (such portion not to be less than $1,000,000.00) shall be discounted by ten percent (10%) on an annualized basis calculated on a 365-day basis for actual days elapsed and (y) any Parent Shares issued pursuant to this Section 2.6(g)(iv) (the “Early Election Shares”) shall be issued pursuant to the terms of this Section 2.6(g)(iv). In order to issue the Early Election Shares, Parent must provide the Stockholders’ Representative written notice of such election, which such notice shall include the portion of the 2026 Performance Amount to be paid through the issuance of such Early Election Shares, within ten (10) trading days after the trading day (but not on the trading day) that Parent publicly announces its earnings for a particular fiscal quarter, provided that, for purposes of clarity, in the event that earnings are announced after the close of trading on any given day, the first trading day following such announcement shall be deemed the trading day of such announcement for purposes of this Section 2.6(g)(iv). The Early Election Shares shall be issued in an amount equal to the 30-Day VWAP (as defined below) of the Per Share 2026 Earnout Payment Amount. “30-Day VWAP” means the daily volume weighted average of actual trading prices (rounded to four decimal places) on NASDAQ for the 30 consecutive trading days starting the first trading day following the issuance of an Early Election notice (the “30-Day Period”) pursuant to this Section 2.6(g)(iv).
