Risk-free interest rate - based on yield rates of non-index linked U.S. Federal Reserve treasury bonds.
 
(2)
Expected volatility - was calculated based on actual historical stock price movements of the Company together with companies in the same industry over a term that is equivalent to the expected term of the option.
 
(3)
Expected life - the expected life was based on the expiration date of the warrants.
 
(4)
Expected dividend yield - was based on the fact that the Company has not paid dividends to its shareholders in the past and does not expect to pay dividends to its shareholders in the future.
