(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 average of 5 and 7 year and the 3-month 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.
(5)  
Management has determined that the probability of a stock offering is 25% for each quarter of the next five years.
(6)  
Management estimates that the range of percentages of existing shares offered in each stock offering will be between 35% of the shares outstanding.
(7)  
Represents the estimated offering price range in future offerings as determined by management.
