[1] During the nine-month period ended September 30, 2013, our warrants liability was reduced as a result of the warrants amendment, as discussed above. Additionally, our warrants liability was further reduced by $385,900 as a result of the exercise of 1,072,500 warrants during such period, whose terms were not affected by the changes made under the warrants amendment. The aggregate reduction in the liability, combining the warrant amendment and this exercise, was $4,776,900. See Note 14.

[2] Effective September 18, 2013, we entered into a consulting agreement with Genesis Select to provide us with a variety of investor relations services. As part of their compensation, we issued to them a warrant to purchase 312,500 shares of our common stock at an exercise price of $0.50 per share. The warrant will vest, monthly, over the initial twelve-month service period of the contract, assuming that the agreement remains in-force, with the first vesting to occur on October 18, 2013. The warrant is substantially similar in nature to those issued in the warrant amendment, discussed above, thus; the warrant is accounted for under the equity method and is not included as a component of our warrants liability as of September 30, 2013. We used the following assumptions in a binomial pricing model to calculate the fair value of the warrant issued to Genesis: estimated volatility – 181%; annualized forfeiture rate – 5%; expected term – 4.96 years; estimated exercise factor – 4%, risk free interest rate – 1.41%; and dividends – 0. Compensation expense associated with these warrants is recognized as a component of general and administrative expense.
