FAIR VALUES OF FINANCIAL INSTRUMENTS      


Cash and cash equivalents, accounts receivable, due from factor, accounts payable and accrued liabilities are carried at, or approximate, fair value because of their short-term nature.


The fair value of the warrant liabilities were measured at fair value using the following assumptions:


Risk free interest rate

0.42%   0.67%  

Expected term

2.4   2.61  

Expected dividends

  0    

Volatility of stock price

132.9%   136.2%  

The warrant liabilities are considered Level 3 liabilities on the fair value hierarchy as the determination of fair value includes various assumptions about of future activities and the Company’s stock prices and historical volatility as inputs.
