7.   Stock Purchase Warrants

On March 15, 2012, the Company entered into a consulting agreement for a financial communications program, for a period of twelve months that began on February 20, 2012. As compensation for such program, the consultant is paid a monthly fee and will be issued a performance warrant exercisable for 250,000 shares of the Company’s common stock based on achievement of certain milestones. Upon initiation of the program, 50,000 of the performance warrants vested. The performance warrant is exercisable for a period of two years from the date the agreement was executed for an exercise price equal to the price of the Company’s common stock on the date of execution. The fair value of the warrant approximated $61,000 and was measured using the Black-Scholes valuation model. The assumptions used by the Company are summarized in the following table:

  

Exercise price   $ 2.20  
Expected dividends     0 %
Expected volatility     108 %
Risk free interest rate     0.37 %
Expected life of warrant     2 years  
Expected forfeitures     0 %
