Each vested and unvested option to purchase shares of common stock of Legacy Matternet outstanding immediately prior to the effective time of the Merger was assumed by the Issuer and converted into an option to purchase shares of common stock equal to the product of (a) the number of shares of common stock subject to such option immediately prior to the effective time of the Merger and (b) 2.0801 (the "Conversion Ratio"), at an exercise price per share equal to (i) the exercise price per share of such option immediately prior to the effective time of the Merger divided by (ii) the Conversion Ratio.

(2) The shares subject to the option shall become vested and exercisable in 48 equal monthly installments from the vesting commencement date.
