 term represents the period that the stock-based awards are expected to be outstanding. Because of the limitations on the sale or transfer 
 or the Company’s common stock as a privately held company as of grant date, the Company does not believe its historical exercise          
 pattern is indicative of the pattern it will experience as a publicly traded company. The Company estimated that the options issued to    
 its holders of Founder Shares will be held for the full ten-year term.                                                                    |

| ● | Volatility:  The Company determined the price volatility factor based on the historical volatilities  
 of selected peer group as the Company did not have a sufficient trading history for its common stock. |

| ● | Dividend yield: The expected dividend assumption is based on the Company’s current expectations      
 about our anticipated dividend policy. The Company currently does not expect to issue any dividends. |
