Stock Options and Warrants

The Company currently has two non-statutory stock option plans, the Fiscal 2001 Non-statutory Stock Option Plan (the “2001 Plan”) and the 2013 Equity Compensation Plan (the “2013 Plan”). Both plans have been adopted by our Board of Directors and approved by our shareholders. Both the 2001 Plan and the 2013 Plan have options available for future issuance. Any common shares issued as a result of the exercise of stock options would be new common shares issued from our authorized issued shares.

During the three months ended June 30, 2018, the Company issued options to purchase 20,000 shares of stock to each of its non-employee board members as an annual stock option grant (for a total of 80,000 options) under the 2001 Plan. During the three months ended June 30, 2017, the Company issued options to purchase 20,000 shares of stock to each of its two non-employee board members as an annual stock option grant (for a total of 40,000 options) under the 2001 Plan.
