The RSUs will vest 25% on June 20, 2027, with the remainder vesting in 12 equal quarterly installments thereafter, subject to the employee's continued employment with Quantum-Si on such vesting dates. The RSUs are subject to the terms and conditions of the 2023 Inducement Plan and a RSU agreement covering the grant.
