Pursuant to the Merger Agreement, at the Effective Time, each award of restricted stock units relating to shares of SkyWater common stock held by a service provider other than a non-employee member of SkyWater's board of directors that was outstanding, whether vested or unvested, automatically converted into a restricted stock unit award corresponding to a number of shares of IonQ common stock based on the Equity Award Exchange Ratio (as defined in the Merger Agreement), and is otherwise subject to the same terms and conditions (including any existing accelerated vesting provisions) as applied immediately prior to the Effective Time, with any related accrued but unpaid dividend equivalent rights carrying over and remaining payable in accordance with such preexisting terms.

3. Represents options to purchase shares of SkyWater common stock.
