When an option is exercised, new common shares are issued by the Company under all five stock-based incentive plans.

Plan Provisions Under the 2013 Equity Incentive Plan

Upon the adoption of the 2013 Plan, the Board of Directors decided that the 2013 Plan would be the only plan under which stock-based awards will be issued by the Company on a going-forward basis. The 2013 Plan provides for the awards of incentive stock options, non-qualified stock options, restricted stock, restricted stock units and other stock-based awards; however, only restricted stock unit awards have been issued through June 30, 2013 under the 2013 Plan. The 2013 Plan states that awards may be granted to such non-employee directors, officers, employees and consultants as the Board of Directors shall in its discretion select. Only employees of the Company are eligible to receive grants of incentive stock option awards. Stock option awards are generally granted at the fair market value of the Company’s common stock on the date of grant. Stock option grants generally vest over periods up to four years, with the first 25% of the grant vesting after one year, and monthly vesting thereafter. Stock option grants generally have a term not to exceed a total of 10 years. As of June 30, 2013, there 1,283,333 shares available for issuance under the 2013 Plan.
