Old Gemini’s 2017 Stock Option and Grant Plan, as amended (the “2017 Plan”), provided for the Company to grant qualified incentive options, nonqualified options, stock grants and other stock-based awards to employees and non-employees to purchase the Company’s common stock. The 2017 Plan was administered by the board of directors, or at the discretion of the board of directors, by a committee of the board of directors.

The exercise price for incentive options was determined at the discretion of the board of directors. All incentive options granted to any person possessing less than 10% of the total combined voting power of all classes of stock may not have an exercise price of less than 100% of the fair market value of the common stock on the grant date. All incentive options granted to any person possessing more than 10% of the total combined voting power of all classes of stock may not have an exercise price of less than 110% of the fair market value of the common stock on the grant date.

The option term for incentive awards may not be greater than ten years from the date of the grant. Incentive options granted to persons possessing more than 10% of the total combined voting power of all classes of stock may not have an option term of greater than five years from the date of the grant. The vesting period for equity-based awards under the 2017 Plan was determined at the discretion of the board of directors, which was generally four years. For awards granted to employees and non-employees with four-year vesting terms, 25% of the options vest on the first anniversary of the grant date and the remaining options vest equally each month for three years thereafter.

Upon completion of the Business Combination, the Company ceased granting awards under the 2017 Plan.

Each Old Gemini option from the 2017 Plan and each option from Old Gemini’s 2015 Stock Option and Grant Plan (the “2015 Plan”) that was outstanding immediately prior to the Business Combination, whether vested or unvested, was converted into an option to purchase a number of shares of common stock (each such option, an “Exchanged Option”) equal to the product (rounded down to the nearest whole number) of (i) the number of shares of Old Gemini common stock subject to such Old Gemini option immediately prior to the Business Combination and (ii) the Conversion Ratio, at an exercise price per share (rounded up to the nearest whole cent) equal to (A) the exercise price per share of such Old Gemini option immediately prior to the consummation of the Business Combination, divided by (B) the Conversion Ratio. Each Exchanged Option will continue to be governed by the same terms and conditions (including vesting and exercisability terms) as were applicable to the corresponding former Old Gemini option immediately prior to the consummation of the Business Combination. All stock option activity was retroactively restated to reflect the Exchanged Options.

As of the Closing Date, the 10,567,508 options and 163,157 restricted stock units (“RSUs”) outstanding under the 2017 Plan and 2015 Plan were converted into 2,303,309 options and 35,561 RSUs, respectively, upon completion of the Business Combination after the effect of the Conversion Ratio. This effect of the Conversion Ratio has been retroactively adjusted throughout the Company’s unaudited condensed consolidated financial statements.

In February 2021, FSDC’s stockholders approved the 2021 Stock Option and Incentive Plan (the “2021 Plan”), pursuant to which 4,264,341 shares of common stock were reserved for issuance. The 2021 Plan provides for the Company to grant incentive stock options or nonqualified stock options for the purchase of common stock, stock appreciation rights, restricted stock awards, restricted stock units, unrestricted stock awards, cash-based awards and dividend equivalent rights to employees, officers, directors and consultants of Gemini. Incentive stock options may only be granted to employees. The 2021 Plan is administered by the plan administrator, which is the Compensation Committee of Gemini’s board of directors, provided therein, which has discretionary authority, subject only to the express provisions of the 2021 Plan, to interpret the 2021 Plan; determine eligibility for and grant awards; determine form of settlement of awards (whether in cash, shares of stock, other property or a combination of the foregoing), determine, modify or waive the terms and conditions of any award; prescribe forms, rules and procedures; and otherwise do all things necessary to carry out the purposes of the 2021 Plan. The number of shares of common stock reserved for issuance under the 2021 Plan automatically increases on January 1 of each calendar year, starting on January 1, 2022 and continuing through January 1, 2031, in an amount equal to 4% of the total number of shares of the Company’s capital stock outstanding on the last day of the calendar month before the date of each automatic increase, or a lesser number of shares determined by the Company’s board of directors. Subject to this provision, the Company added 1,728,326 shares available for grant to the 2021 Plan effective January 1, 2022. As of June 30, 2022, 2,162,435 shares remained available for future issuance under the 2021 Plan.

The exercise price of each stock option granted under the 2021 Plan will be 100% of the fair market value of the underlying stock subject to the award, determined as of the date of the grant, or such higher amount as the plan administrator may determine in connection with

the grant, and the term of stock option may not be greater than ten years. The vesting and other restrictions are determined at the discretion of the plan administrator.

In February 2021, the Company’s board of directors approved the 2021 Inducement Plan. The 2021 Inducement Plan is a non-stockholder approved stock plan under which the Company grants equity awards to induce highly-qualified prospective officers and employees who are not currently employed by the Company to accept employment and provide them with a proprietary interest in the Company. The Company intends that the 2021 Inducement Plan be reserved for persons to whom the Company may issue securities without stockholder approval as an inducement pursuant to Rule 5635(c)(4) of the Marketplace Rules of the NASDAQ Stock Market, Inc. The 2021 Inducement Plan is administered by the board of directors or the Compensation Committee of the board, which determines the types of awards to be granted, including the number of shares subject to the awards, the exercise price and the vesting schedule. Awards granted under the 2021 Inducement Plan expire no later than ten years from the date of grant. As of June 30, 2022, 983,949 shares were available for issuance under the 2021 Inducement Plan.

In July 2021, the Company’s board of directors approved the 2021 Employee Stock Purchase Plan (“2021 ESPP”). The first offering period under the 2021 ESPP began on December 1, 2021. The Company has not yet issued any shares under the 2021 ESPP. The Company recorded $6 thousand and $22 thousand of stock-based compensation expense related to the 2021 ESPP during the three and six months ended June 30, 2022, respectively. As of June 30, 2022, 420,591 shares remained available for future issuance under the 2021 ESPP. The number of shares of common stock reserved for issuance under the 2021 ESPP automatically increases on January 1 of each calendar year, starting on January 1, 2023 and continuing through January 1, 2031, in an amount equal to the least of (a) 1% of the total number of shares of the Company’s capital stock outstanding on the last day of the calendar month before the date of each automatic increase, (b) 430,551 shares of common stock, or (c) such number of shares determined by the Company’s board of directors.
