The right to exercise these options shall vest and become exercisable from February 23, 2016 to February 1, 2017. The vesting date varies for each option agreements. The options have exercise prices ranging from $0.30-$0.80 per share and will expire ten years from the grant date, unless terminated earlier as provided by the option agreements. During April 2016, the Company agreed to extend an employee's previously issued stock options of 22,500 until April 29, 2016. In April 2016, this employee exercised 5,000 shares of their stock options at $0.30 per share. The remaining shares of their stock options expired by the end of April 2016. During July 2016, the Company issued 320,000 options to an employee. The right to exercise these options shall vest and become exercisable on December 31, 2021.

The exercise price is $0.51-$0.56 per share and will expire ten years from the grant date, unless terminated earlier as provided by the option agreements. The fair value of each option award was estimated on the date of grant using the Black-Scholes option valuation model using the assumptions noted as follows: expected volatility was based on a representative peer group of small public companies in their industry segment as the Company has a limited stock history. The expected term of options granted was determined using the simplified method under SAB 107 and represents the mid-point between the vesting term and the contractual term. The risk-free rate is calculated using the U.S. Treasury yield curve, and is based on the expected term of the option. The Black-Scholes option pricing model was used with the following weighted average assumptions for options granted during the twelve months ended September 30, 2017 and 2016, respectively:
For employees | September 30, 2017 |  | September 30, 2016 |
Risk-free interest rate |  |  | 1.64% - 1.75 | % |  |  | 1.11% - 1.43 | %
Expected option life | 5.5 - 6.5 years |  | 4.5 years |
Expected volatility |  |  | 97.6% - 99.1 | % |  |  | 80.2% - 83.6 | %%
Expected dividend yield |  |  | 0.00 | % |  |  | 0.00 | %
Exercise price |  | $ | 0.40 - $0.56 |  |  | $ | 0.30 - $0.88 |
For non-employees | September 30, 2017 |  | September 30, 2016 |
Risk-free interest rate |  |  | 2.27 | % |  |  | 1.74 | %

Expected volatility |  |  | 115.70 | % |  |  | 104.70 | %
