In Trine’s initial public offering, it sold units at a price of $10.00 per unit, which consisted of one share of Common Stock, $0.0001 par value, and one-half of a redeemable warrant (each, a “Public Warrant”). Each whole Public Warrant entitles the holder to purchase one share of Common Stock at a price of $11.50 per share and became exercisable as of 30 days from the date of the Business Combination. Unless earlier redeemed, the Public Warrants will expire five years from the completion of the Business Combination.
