[1] 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 having occurred 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 in equity and is not included as a component of our warrants liability as of December 31, 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%; expected term 4.96 years; estimated exercise factor 4, risk free interest rate 1.41%; and dividends 0. Expense associated with this warrant is recognized as a component of general and administrative expense over the one-year vesting term of the warrant.
