At the election of the Sponsor, all or a portion of the unpaid principal amount of the Note may be converted into warrants of the Company, each warrant exercisable for one-half of one share of common stock of the Company upon the consummation of an initial business combination (the “Conversion Warrants”), equal to: (x) the portion of the principal amount of the Note being converted, divided by (y) $0.50, rounded up to the nearest whole number of warrants.
