Re: Assignment with Globalization Partners
Dear Jeff,
On behalf of Rapport Therapeutics, Inc. (the “Company”) and in connection with your employment with Globalization Partners to provide services to the Company, I am pleased to confirm that, subject to approval of the Company’s Board of Directors (the “Board”) and your continued assignment to Rapport Therapeutics on the date of grant or issuance, the Company shall grant to you a non-qualified option to purchase 300,000 shares of the Company’s common stock (the “Stock Option Grant”). The exercise price of the Stock Option Grant shares will be at least equal to the fair market value of the Company’s common stock on the date of the grant. The Stock Option Grant will be subject to the standard terms and conditions of the Company’s 2024 Stock Option and Incentive Plan and the applicable equity award agreement (the “Equity Documents”), including with respect to vesting as follows: 25% of the Options shall vest on the first anniversary of your Start Date and an additional 2.08334% per month for the next thirty-six successive months, subject to your continued service to the Company at each such vesting date, such that the Options shall be fully vested upon the fourth (4th) anniversary of your Start Date.
If (i) your employment is terminated by Globalization Partners at the direction of the Company without Cause (as defined in the Addendum) and (ii) the date of such termination (the “Date of Termination”) occurs during the period commencing 3 months prior to a Sale Event (as such term is defined in the Equity Documents) and ending 12 months following such Sale Event (the “Change in Control Period”), and notwithstanding anything to the contrary in any applicable option agreement or other stock-based award agreement, subject to the signing of a general release of claims against the Company and all related persons and entities (the “Release”) and such Release becoming fully effective within the time period set forth in the Release (but in no event more than 60 days after the Date of Termination), all stock options and other stock-based awards held by you that are subject solely to time-based vesting (the “Time-Based Equity Awards”) shall immediately accelerate and become fully vested and exercisable or nonforfeitable as of the later of (i) the Date of Termination (or, if later, the Sale Event) or (ii) the effective date of the Release (the “Accelerated Vesting Date”), provided that in order to effectuate the accelerated vesting contemplated by this subsection, the unvested portion of the Executive’s Time-Based Equity Awards that would otherwise terminate or be forfeited on the Date of Termination will be delayed until the earlier of (A) the later of the effective date of the Release or the date of the Sale Event (at which time acceleration will occur), or (B) the earlier of the date that the Release can no longer become fully effective or, to the extent the Date of Termination occurs prior to a Sale Event, the date that is three (3) months following the Date of Termination if a Sale Event has not been consummated on or prior to such date (at which time the unvested portion of the Executive’s Time-Based Equity Awards will terminate or be forfeited). Notwithstanding the foregoing, no additional vesting of the Time-Based Equity Awards shall occur during the period between the Date of Termination and the Accelerated Vesting Date.
