Notes Payable | NOTE 6 - Notes Payable On September 29, 2017, the Company entered into amendments (the “Amendments”) to the October 17, 2016 Secured Convertible Promissory Notes and Warrants to purchase shares of the Company’s common stock, pursuant to which, among other things set forth in the Amendments, (1) the exercise price of the Warrants was reduced from $4.13 per share to $2.00 per share, and (2) the conversion price of the Notes was reduced from $4.13 per share to $2.00 per share. Under the Amendments, we paid the Holders an aggregate amount equal to $500,000 (representing 50% of the outstanding principal balance of the Notes) plus all accrued interest on the Notes. In consideration of the foregoing, the Holders agreed to, among other things, extend the payment date of the remaining 50% of the outstanding principal balance of the Notes from October 17, 2017 to the earlier of May 18, 2018 or the closing of our next underwritten public offering of securities in which we raise gross proceeds of at least $3,000,000 (should we elect to commence and close such an offering of securities). In December 2017, the Holders Converted $400,000 of the $500,000 Notes principal and $8,556 of accrued interest on one of the notes into 204,278 shares of common stock and exercised 56,000 of the warrants @ $2.00 per share for 56,000 additional shares of common stock. In April 2018, the Company entered into an amendment of the remaining $100,000 Note which extended the payment due date to October 18, 2018, deleted the covenant providing for acceleration of the payment due date in the event of a public offering closing of at least $3,000,000 and required the Company to pay the balance of accrued and unpaid interest as of the effective date of the amendment. The Company paid the $8,761 balance of accrued interest to the holder in April 2018. In May 2018 the Holder Converted $50,000 of the Note principal into 25,000 shares of common stock and executed a cashless exercise of 24,000 of the warrants for an additional 4,800 shares of common stock. In October 2018, the Note was amended pursuant to which the due date was extended to April 18, 2019. Under the amendment, Sigma paid the $3,444 total accrued interest balance as of October 18, 2018 and agreed to make future payment dates of accrued interest on December 31, 2018 and April 18, 2019. At December 31, 2018 the Company had the remaining $50,000 Convertible Note outstanding plus accrued interest of $1,028. The accrued interest amount was paid to the holder in January 2019.
