Shares and warrants issued in the July 30, 2012 and August 28, 2012 sales were sold pursuant to the Company's currently effective shelf registration. Warrants issued in the July 30, 2012 and August 28, 2012 sales' are exercisable for a period of five years beginning on the closing date of the offering at an exercise price of $4.45 per share (150% of the aggregate offering price for a share of common stock and corresponding warrant). The warrants issued in connection with the October 3, 2012 sale are exercisable for a period of five years beginning on the six-month anniversary of the closing date at an exercise price of $6.73 per share (approximately 150% of the aggregate offering price). The securities issued in the October 3, 2012 sale were not registered under the Securities Act of 1933, as amended, or any state securities laws, and were issued and sold in a private placement pursuant to Regulation D of the Securities Act. The Company subsequently filed a Form S-3 registration with the US Securities and Exchange Commission which was declared effective on December 26, 2012 that covers the resale of the shares by the purchaser and the shares issuable upon exercise of the warrants. (b) Options and Warrants (i) Employee Options In 2008, the shareholders approved the Company's 2008 Equity Incentive Plan which provides for the granting of both incentive stock options at the fair market value at the date of grant and nonqualified stock options at the fair market value at the date of grant to employees or non-employees who, in the determination of the Board of Directors, have made or may make significant contributions to the Company in the future. The Company may also award stock appreciation rights, restricted stock, or restricted stock units under this plan. The Company initially reserved 750,000 shares of its common stock for issuance under this plan, and 611,692 options and other awards were available for issuance under this plan as of December 31, 2013. At the discretion of the Board of Directors, options expire in ten years or less from the date of grant and are generally fully exercisable upon grant but in some cases may be subject to vesting in the future. Full payment of the exercise price may be made in cash or in shares of common stock valued at the fair market value thereof on the date of exercise, or by agreeing with the Company to cancel a portion of the exercised options. The Company granted no employee options during 2012 and 2011. The Company granted 499,700 fully vested options during 2013 and recorded share-based compensation of $1,431,620.
