5. Commitments and Contingencies Employment Agreement On June 14, 2018, we entered into an employment agreement with Mr. Mannine pursuant to which he was engaged to serve as our Chief Executive Officer. The initial term of the agreement expires in June 2023, subject to successive automatic one-year renewals unless a non-renewal notice is received by either party at least 90 days prior to the expiration of the then current renewal term. Mr. Mannine?s compensation includes:  an annual base salary of $130,000, subject to an annual review with an increase of at least 5% per annum as determined by the board of directors;  an annual bonus as determined by the board of directors;  a grant of 10-year options to purchase 100,000 shares of our common stock at an exercise price of $0.225 per share which vest upon the effectiveness of a registration statement to be filed with the Securities and Exchange Commission;  participation in all benefit plans we may offer our employees; and  20 paid vacation days annually. Mr. Mannine's employment agreement may be terminated, and he is entitled to certain payments upon such termination, as follows:  if we should terminate Mr. Mannine?s employment without ?cause? or if he should resign for ?good reason" or if a ?change of control? occurs, we are obligated to pay him a lump-sum severance payment equal to the sum of three months? base salary, plus one month for every year he was employed and 50% of three years annual bonus (based on the prior year?s compensation);  if Mr. Mannine?s employment is terminated as a result of his death or disability, he is entitled to receive his base salary and a pro-rata annual bonus, if any, based on the year during which such termination is effective ; or  if we should terminate Mr. Mannine for ?cause,? or if he voluntarily terminates the agreement, he is entitled to receive his base salary only through the date of termination, and he is not be entitled to any other compensation for the calendar year during which the termination occurs or any subsequent calendar period, including, but not limited to, any annual bonus, if any, that has not already been paid. The employment agreement with Mr. Mannine contains customary confidentiality, non-compete and indemnification clauses. Mr. Mannine contributed part of his salary totaling $20,654 for the three months ended March 31, 2019, which was recorded as an increase in paid in capital. Commitments On March 8, 2018, we entered into an advisory agreement with a scientific advisor to provide certain services to us. Pursuant to the agreement, we issued 100,000 five year common stock warrants at an exercise price of $0.90. Such warrants vest subject to certain milestones. As of March 31, 2019 and December 31, 2018, 33,333 of these warrants have vested. We determined that the warrant had an initial fair value of $1,905. We estimated the fair value of this warrant using the Black-Scholes option pricing model, based on the following assumptions: the recent cash offering price of $0.225 as the estimated fair value of the underlying common stock at the valuation measurement date; no dividend yield for all of the years; expected volatility of 45%; risk-free interest rate of 2.63% and an expected life of 5 years. During the three months ended March 31, 2019 and 2018, we have recorded stock-based compensation expense of $143 and $111, respectively which is included in our Selling, general and administrative expense on the accompanying Statements of Operations. Contingencies In April 2016, we entered into a Promotion and Royalty Agreement (the ?Agreement?) with a consultant to obtain certain promotional services from him (the ?Promoter?), including the use of his name and appearance. In consideration for the services rendered by the Promoter, we agreed to use commercially reasonable efforts to promote and sell a book authored by him (the ?Book?) and to pay him a percentage of the sales of the Book after deductions for all direct costs of fulfilling such sales (the ?Royalty?). During the course of 2017, the Promoter initiated a series of informal claims and filed unauthorized uniform commercial code financing statements (?UCC Liens?) in several states as liens against us and certain of our officers, directors, and founders, alleging non-payment for the Royalty amounts due under the Agreement. We dispute the Promoter?s claims and have determined that any and all amounts due to the Promoter under the Agreement have been paid in full. We have succeeded in removing certain of the UCC Liens and are pursuing action to remove the remaining unauthorized UCC Liens. We do not believe that the claims of the Promoter are valid in any respect.
