COMMON STOCK, STOCK OPTIONS AND WARRANTS | 6. COMMON STOCK, STOCK OPTIONS AND WARRANTS Private Offerings and Common Stock Issued for Services and Release Agreements In February 2017, the Company completed its 2016 private placement (the "2016 Offering"). The Company sold 128,017 units at $6.00 per unit for gross proceeds of $768,100. Each unit consisted of (i) one share of common stock and (ii) a five-year warrant to purchase one share of common stock at an exercise price of $8.25 per share. The placement agent received a 10% cash commission on the gross proceeds, an expense allowance equal to 3% of the proceeds, and warrants to purchase 12,802 shares of common stock at an exercise price of $8.25 per share. The estimated fair value of the 128,017 warrants issued to the investors was $587,592 and the estimated fair value of the 12,802 warrants issued to the placement agent was $58,759. The placement agent commissions and expense allowance was $99,853. Other costs of the placement were $176,896. During January 2017, the Company issued 29,729 shares of its common stock for investor relations services. The $298,774 fair value of the common stock was expensed during the year ended September 30, 2017.

The Company expensed the $45,476 as a settlement expense during the year ended September 30, 2017. On June 8, 2017, the Company entered into release agreements with the investors in the 2016 Offering where each investor released the Company from the restrictions included in the unit purchase agreements. In exchange, the Company agreed that (i) in the event that a financing is conducted at a price per share or price per unit lower than $6.00, then the Company will issue additional shares to each investor sufficient to effectively reprice the sale of the 2016 Offering units to the lower price; (ii) in the event that the financing is conducted at a price per share or price per unit less than the $8.25 exercise price of the warrants issued in the 2016 Offering then the exercise price of the warrants shall be reduced to the lower price; and (iii) the Company will give each investor no less than 6 hours of notice before the closing of any subsequent financing, through and including the Company's 2017 registered public offering, and each investor shall have a 6-hour option to purchase up to 20% of the securities sold in such offering. In connection with these agreements the Company reclassified the $641,385 fair value of the 140,819 warrants issued in the 2016 Offering to derivative warrant liability on June 8, 2017.

Stock Option Plans Pursuant to its 2014 Stock Incentive Plan (the "2014 Plan") the Company reserved 866,667 shares of common stock for issuance to employees, directors and consultants. The Board of Directors (or committees and/or executive officers delegated by the Board of Directors) may grant stock options, stock appreciation rights, restricted stock, restricted stock units, other stock-based awards and cash-based awards. As of September 30, 2019, there were options to purchase 856,039 shares outstanding under the 2014 Plan, options to purchase 4,829 shares were exercised, and 5,799 shares were available for future grants. On February 7, 2018, our stockholders approved the 2018 Omnibus Stock Incentive Plan (the "2018 Plan") and the Company reserved 2,000,000 shares of common stock for issuance to employees, directors and consultants. Pursuant to the 2018 Plan, the Board of Directors (or committees and/or executive officers delegated by the Board of Directors) may grant stock options, stock appreciation rights, restricted stock, restricted stock units, other stock-based awards and cash-based awards. As of September 30, 2019, there were options to purchase 915,000 shares outstanding under the 2018 Plan and 1,085,000 shares were available for future grants. The fair value of each stock option award is estimated on the date of grant using the Black-Scholes option pricing model. Due to its limited operating history and limited number of sales of its common stock, the Company estimated its volatility in consideration of a number of factors including the volatility of comparable public companies through December 31, 2018. Since January 1, 2019, the Company has estimated its volatility using the trading activity of its common stock. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant commensurate with the expected term assumption. The expected term of stock options granted to employees and directors, all of which qualify as "plain vanilla," is based on the average of the contractual term (generally 10 years) and the vesting period. For non-employee options, the expected term is the contractual term. The following assumptions were used in determining the fair value of stock option grants for the years ended September 30, 2019, 2018 and 2017:
|  | 2019 |  |  | 2018 |  |  | 2017 |
Risk-free interest rate |  |  | 2.18 – 2.53 | % |  |  | 2.78 – 2.99 | % |  |  | 1.79 – 1.90 | %
Expected dividend yield |  |  | 0 | % |  |  | 0 | % |  |  | 0 | %
Expected term |  |  | 6.50 – 10 years |  |  |  | 6.50 – 10 years |  |  |  | 6.50 – 10 years |
Expected volatility |  |  | 119 – 121 | % |  |  | 116 | % |  |  | 85 – 108 | %
