The number of First Warrant instruments has not been determined as the First Warrant provides the Lenders with 25% warrant coverage, with the warrant exercise price to be equal to the offering price in the Company’s proposed public offering, or, in the event the Loan Amount are converted into ordinary shares, the warrant exercise price will be equal to the applicable closing bid price of the Company’s shares at the time of the conversion of the Loan Amount. However, based on the share price of the Company as of December 31, 2019, the number of the First Warrant would have been 20,896,789 shares. |
