(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 the Company's stockholders approved amendments to the 2008 Equity Incentive Plan to increase the number of shares issuable under the plan by 1,000,000 and 750,000 shares on June 13, 2013 and June 9, 2011, respectively. Options and other awards for 377,942 shares were available for issuance under this plan as of December 31, 2014.
