_______________

(1)
The Series A Preferred Stock convert on a 1:1 basis into common stock, but differ in value from common stock due to the downside protection relative to common stock in the event the Company liquidates, and the downside protection, if, after four years, the holder has not converted and the stock is below $3.00. The fair value of Series A Preferred Stock was determined using a Monte-Carlo simulation following a Geometric Brownian Motion, using the following assumptions: annual volatility of 75%, risk-free rate of 0.9% and dividend yield of 0.0%. The model also utilized the following assumptions to account for the conditions within the agreement: after four years, if the simulated common stock price fell below a price of $3.00 per share, the convertible preferred stock would automatically convert to common stock on a 1:1 basis moving forward at a price of $3.00 per share and a forced conversion if the simulated stock price exceeded $8.00 per share.
(2)
The fair value of convertible subordinated notes payable was determined based on its current yield as compared to that of those currently outstanding in the marketplace. Management reviewed the convertible note agreement and determined that the note's interest rate is a reasonable representative of a market rate; therefore the face or principal amount of the loan is a reasonable estimate of its fair value.
(3)
The fair value of the common stock warrants was determined using a Monte-Carlo simulation following a Geometric Brownian motion, using the following assumptions: annual volatility of 75%, risk-free rate of 0.9%, dividend yield of 0.0% and expected life of 5 years. Because the dilutive down-round financing was subject to stockholder approval, which had not happened at the time of the valuation, the model utilized the assumption that the down-round financing would not occur within the simulation.
