(1)  
The market value of common stock is based on an enterprise valuation.
  
(2)  
The risk-free interest rate was determined by management using the Treasury Bill as of the respective measurement date.
 
(3)  
Because the Company does not have adequate trading history to determine its historical trading volatility, the volatility factor was estimated by management using the historical volatilities of comparable companies in the same industry and region.
 
(4)  
Management determined the dividend yield to be 0% based upon its expectation that it will not pay dividends for the foreseeable future.
