7. | Stock Purchase Warrants
On October 25, 2012, the Company entered into a Common Stock Purchase Agreement with certain accredited investors. As part of this agreement, the Company issued warrants to purchase 635,855 shares of common stock to the placement agent, or its permitted assigns. The warrants have an exercise price of $1.60 and a life of five years. The warrants vested immediately and expire October 25, 2017. Since these warrants were granted as part of an equity raise, the Company has treated them as a direct offering cost. The result of the transaction has no affect to equity. As of June 30, 2013, all the warrants were outstanding. 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 stock price 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 of issuance for an exercise price equal to the price ($2.20 per share) of the Company’s common stock on the date of execution (March 15, 2012). In March 2013, the performance warrants’ vesting period was extended to March 14, 2014. All other provisions of the performance warrants remain unchanged. The incremental expense related to the modification of the warrants of approximately $76,000 will be recognized over the one year extension period. On December 20, 2011, the Company entered into a consulting agreement for financial advisory services, for a period of twelve months. As compensation for such services, the consultant was paid a monthly fee and on February 2, 2012, was issued warrants exercisable for 100,000 shares of the Company’s common stock. The warrant is exercisable upon issuance for a period of five years from the date of issue at an exercise price equal to the price ($1.14) of the Company’s common stock on the date of issue. As of June 30, 2013, all the warrants were outstanding. A summary of warrant activity for the Company for the six months ended June 30, 2013 and for the year ended December 31, 2012 is as follows:
