In connection with the closing of the Business Combination, the 2021 Equity Incentive Plan (the "2021 Plan") was adopted and approved by the Company's board of directors.

Prior to the Business Combination, the Company maintained its 2017 Stock Option Plan (the “2017 Plan”).

Upon the adoption and approval of the 2021 Plan, the 2017 Plan was terminated and each outstanding vested or unvested option, as required under the 2017 Plan, was converted to the 2021 Plan, multiplied by the Exchange Ratio, with the same key terms and vesting requirements.

Awards granted under the 2017 Plan had time-based vesting or performance-based with a market condition vesting requirements. Stock options granted under the 2017 Plan expire on the tenth anniversary of the grant date.

Additionally, the Company maintained a Phantom Stock Plan (the “Phantom Plan”), which provided for the issuance of phantom shares of CCCIS’s common stock (“Phantom Shares”) to eligible employees under the 2017 Plan. Awards under the Phantom Plan were settled in cash and thus accounted for as liability awards.

Phantom Shares vested under the same time-based or performance-based with a market condition as the stock options granted under the 2017 Plan. Upon consummation of the Business Combination, the outstanding Phantom Shares were settled in cash in November 2021.
