Subsequent Events [Text Block]	NOTE 16 : SUBSEQUENT EVENTS Stock Option and Incentive Plan June 27, 2018, the Company granted 2,300,000 options to the Chief Executive Officer and 700,000 to the Chief Financial Officer (collectively, the “2018 Liability Options”). Each option was exercisable for an equivalent number of shares of Company common stock. The 2018 Liability Options contained a “Net Cash Exercise Provision” so that if at the time the 2018 Liability Options were exercised the Company could not deliver shares of Common Stock to the optionee (including, for example, if there were insufficient shares available under the Plan at the time of exercise), then in lieu of the optionee paying the exercise price and the Company issuing shares of stock, the option would only be exercised on a cash “net basis” requiring that the Company pay cash in an amount equal to the excess of the fair market value of the Common Stock over the option exercise price. On January 13, 2019, the Company, CEO and CFO agreed to cancel and terminate the 2018 Liability Options so they are no longer outstanding and of no further force and effect. On January 13, 2019, the Company granted a new option to the CEO to purchase 2,300,000 shares of Common Stock and a new option to the CFO to purchase 800,000 shares of Common Stock (the “2019 Options”). The 2019 Options: (i) have an exercise price equal to the fair market value of Common Stock on the date of grant which was $1.36 per share, (ii) do not contain a Net Cash Exercise provision, (iii) are granted pursuant to the terms and conditions of the Plan as amended by the Board of Directors on January 13, 2019, to include shares issuable upon exercise of the 2019 Options and other changes to the Plan so that the 2019 Options do not conflict with the Plan (the “Amended Plan”), (iv) vest and are exercisable in accordance with the vesting schedule related to the 2018 Liability Options; provided, however, that the 2019 Options are not exercisable unless and until the Company’s stockholders approve the Amended Plan to increase the authorized number of shares available for grant under the Plan as only 3,575 options were available for grant as of December 31, 2018, and (vi) are subject to and conditioned the 2019 Option Agreements with the optionees and the employment agreements with the optionees. The above actions were unanimously approved by the disinterested members of the Board of Directors. The above actions are intended to eliminate the Company’s potential liability associated with the Net Cash Exercise Provision of the liability options, and to allow the stockholders of the Company the opportunity to vote on the Amended Plan, which includes shares issuable upon exercise of the 2019 Options. Warrant Exercises In March 2019, the Company received approximately $11.3 million from exercises of warrants issued on May 30, 2018. As a result of the warrant exercises, the Company retired approximately 2.8 million warrants and issued approximately 2.8 million shares of common stock.

to the Chief Financial Officer (collectively, the

not

deliver shares of Common Stock to the optionee (including, for example, if there were insufficient shares available under the Plan at the time of exercise), then in lieu of the optionee paying the exercise price and the Company issuing shares of stock, the option would only be exercised on a cash “net basis” requiring that the Company pay cash in an amount equal to the excess of the fair market value of the Common Stock over the option exercise price.

January 13, 2019,

2,300,000

shares of Common Stock and a new option to the CFO to purchase
