Description of service agreement The Company entered into a services agreement whereby it agreed to issue warrants to purchase 50,000 shares of common stock of the Company which vested immediately. The warrants are exercisable at $1.17 per share and expire three years from the date of issuance. The fair value of the warrants were valued on the date of grant at $28 using the Black-Scholes option-pricing model with the following parameters: (1) risk-free interest rate of 0.22%; (2) expected life in years of 3.0; (3) expected stock volatility of 73.06%; and (4) expected dividend yield of 0%. The Company recorded $3 as general and administrative expense in the accompanying condensed consolidated statement of comprehensive loss in relation to the consulting agreement for both the three and six months ended June 30, 2020. As of June 30, 2020, the Company has recorded a prepaid expense which will be recognized through December 31, 2020, in the amount of $25 related to the fully vested nonforfeitable shares of common stock and warrants issued for which services have not been rendered. On July 10, 2020 and August 3, 2020, the Company issued an aggregate of 50,000 shares of common stock upon exercise of the warrant which resulted in aggregate proceeds of approximately $59.
