|Common stock price per share (in Dollars per share)
|Warrant expire term
|Warrants exercise description
|The private warrants are identical to the public warrants underlying the units offered by the Company’s prospectus except that (i) each private warrant is exercisable for one share of common stock at an exercise price of $11.50 per share, and (ii) such private warrants will be exercisable for cash (even if a registration statement covering the shares of common stock issuable upon exercise of such warrants is not effective) or on a cashless basis, at the holder’s option, and will not be redeemable by us, in each case so long as they are still held by the initial purchasers or their affiliates. The private warrants purchased by CleanTech Investments will not be exercisable more than five years from the effective date of the registration statement, of which the Company’s prospectus forms a part, in accordance with FINRA Rule 5110(g)(8), as long as Chardan Capital Markets, LLC or any of its related persons beneficially own these private warrants.
|Public warrants exercisable, description
|The Company may call the outstanding warrants for redemption (excluding the private warrants but including any warrants already issued upon exercise of the unit purchase option), in whole and not in part, at a price of $0.01 per warrant: ●at any time while the warrants are exercisable, ●upon not less than 30 days’ prior written notice of redemption to each warrant holder, ●if, and only if, the reported last sale price of the shares of common stock equals or exceeds $16.50 per share, for any 20 trading days within a 30-day trading period ending on the third business day prior to the notice of redemption to warrant holders, and ●if, and only if, there is a current registration statement in effect with respect to the shares of common stock underlying such warrants at the time of redemption and for the entire 30-day trading period referred to above and continuing each day thereafter until the date of redemption. The right to exercise will be forfeited unless the warrants are exercised prior to the date specified in the notice of redemption. On and after the redemption date, a record holder of a warrant will have no further rights except to receive the redemption price for such holder’s warrant upon surrender of such warrant.
|Description of business combination
|In addition, if the Company issues additional shares of common stock or equity-linked securities for capital raising purposes in connection with the closing of the initial Business Combination at a newly issued price of less than $9.20 per share of common stock (with such issue price or effective issue price to be determined in good faith by the board of directors and, in the case of any such issuance to the Company’s initial stockholders or their affiliates, without taking into account any founder shares or private warrants held by them, as applicable, prior to such issuance), the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the newly issued price and the $16.50 per share redemption trigger price described below under will be adjusted (to the nearest cent) to be equal to 165% of the market value (the volume weighted average trading price of the common stock during the 20 trading day period starting on the trading day prior to the consummation of an initial Business Combination).
