Public warrants description				Each Public Warrant entitles the holder to the right to purchase one share of common stock at an exercise price of $11.50 per share. No fractional shares were issued upon exercise of the Public Warrants. The Company may redeem the outstanding warrants, for $0.01 per warrant, upon not less than 30 days’ prior written notice of redemption given after the warrants become exercisable, if the reported last sale price of the common stock equals or exceeds $18.00 per share (as adjusted for stock dividends, sub-divisions, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period commencing after the warrants become exercisable and ending on the third trading day before the Company sends the notice of redemption to the warrant holders. Upon issuance of a redemption notice by the Company, the warrant holders may, at any time after the redemption notice, exercise the Public Warrants for cash, or on a cashless basis.
