From October 2016 to December 31, 2016, Series B Stockholders converted 461 shares of its preferred stock to common stock, resulting in the issuance of 1,152,500 shares of common stock.

In October 2016, the Company entered into a technology license agreement with a third-party manufacturing company in order to biosynthetically manufacture cannabinoids. The terms of the agreement called for the issuance of 100,000 shares of common stock. The Company recorded $50,000 as research and development expense for the fourth quarter of 2016 to reflect the fair market value of the common stock issued. The fair market value was determined utilizing the Company's closing stock price as of the approval date of the license agreement by the Company’s Board of Directors.

In December 2016, a Series C Preferred stockholder converted 39 shares of its preferred stock to common stock as allowed under the Series C Preferred Stock Agreement, resulting in the issuance of 97,500 shares of common stock at an effective price of $0.40 per share. On December 29, 2016, as a result of the signing of the Series D Preferred Stock Agreement (discussed below), the conversion price of the Series B and Series C Preferred Stock was reset to $0.25. From the date of this reset to December 31, 2016, a Series C Stockholder converted 75 shares of its preferred stock to common stock, resulting in the issuance of 300,000 shares of common stock.

In March 2017, the Company issued 605,000 shares of common stock with par value of $0.001 to a third party in exchange for advisory services performed related to raising additional capital. The Company recorded $187,550 as general and administrative expense for the first quarter of 2017 to reflect the fair market value of the common stock issued.

For the nine months ended September 30, 2017, a Series C Preferred stockholder converted 386 shares of its preferred stock to common stock as allowed under the Series C Preferred Stock Agreement, resulting in the issuance of 1,544,000 shares of common stock at an effective price of $0.25 per share.

Preferred Stock

The Company has authorized 20,000,000 shares of preferred stock with a par value of $0.001 per share.

Redeemable Convertible Series B Preferred Stock: In August 2015, the Company sold 5,000 shares of Series B Convertible Preferred Stock and warrants to purchase 6,250,000 shares of the Company's common stock for an aggregate purchase price of $1,000 per share resulting in gross proceeds of $5.0 million. Each share of preferred stock is convertible into 1,250 shares of common stock which results in an effective conversion price of $0.80 per common share and can be converted by the holder at any time. The Series B Preferred Stock also has a "down-round" protection feature provided to the investors if the Company subsequently issues or sell any shares of common stock, stock options, or convertible securities at a price less than the conversion price of $0.80 per common share. The conversion price is automatically adjusted down to the price of the instrument being issued. In October 2016, as a result of the Series C Preferred Stock Agreement (as discussed below), the conversion price of the Series B Preferred Stock was reset to $0.40. On December 29, 2016, as a result of the Series D Preferred Stock Agreement (as discussed below), the conversion price of the Series B Preferred Stock was reset to $0.25. The Series B Preferred Stock has liquidation preference over other preferred shares and common stock and have voting rights equal to the number of common shares into which each holder's preferred stock is convertible as of the record date. If dividends are declared on the common stock, the holders of the preferred stock shall be entitled to participate in such dividends on an as-if converted basis. The warrants are exercisable at a price of $1.15 per share, subject to reset, and expire five years from the issuance date.

In the event of any liquidation, dissolution or winding up of the Company, either voluntary or involuntary, Series B Preferred stockholders receive an amount per share equal to the conversion price of $0.25, subject to down-round adjustment, multiplied by the as-if converted share amount of 13,165,500 common shares, totaling $3.291 million. If upon the liquidation, the assets are insufficient to permit payments to the Series B holders, all assets legally available will be distributed in a pro rata basis among the Series B holders in proportion to the full amounts they would otherwise be entitled to receive. Any remaining assets are distributed pro rata among the common stockholders.

Subject to certain trigger events occurring, the Series B Preferred stockholders have the right to force the Company to redeem the shares of preferred stock at a price per preferred share equal to the greater of (A) 115% of the conversion amount and (B) the product of (1) the conversion rate in effect at such time and (2) the greatest closing sale price of the Common Stock during the period beginning on the date immediately preceding such triggering event and ending on the date such holder delivers the notice of redemption. Such triggering events include:

As certain of these triggering events are considered to be outside the control of the Company, the Series B Preferred Stock is considered to be contingently redeemable convertible and as a result, has been classified as mezzanine equity in the Company's balance sheet. As further described in Note 8, Series B Preferred Stock Amendment, we amended the terms of the Series B Preferred Stock to exclude certain financing transactions from triggering the redemption right described above.

In December 2015, a Series B Preferred stockholder converted 500 shares of its preferred stock to common stock at the conversion rate of 1,250:1 resulting in the issuance of 625,000 shares of common stock. In March 2016, another Series B Preferred stockholder converted 8 shares of its preferred stock to common stock at the same ratio resulting in the issuance of 10,000 shares of common stock. In October 2016, as a result of the Series C Preferred Stock Agreement (discussed below), the conversion price of the Series B Preferred Stock was reset to $0.40. From October 2016 to December 31, 2016, Series B Stockholders converted 461 shares of its preferred stock to common stock, at the conversion rate of 2,500:1 resulting in the issuance of 1,152,500 shares of common stock. On December 29, 2016, as a result of the Series D Preferred Stock Agreement (as discussed below), the conversion price of the Series B Preferred Stock was reset to $0.25. For the three and nine months ended September 30, 2017, Series B stockholders converted 84 and 739.625 shares, respectively, at a conversion rate of 4000:1 resulting in the issuance of 336,000 and 2,958,500 shares of common stock. As a result of these conversions, the liquidation preference for the Series B Preferred Stock has been reduced to $3.291 million as of September 30, 2017.

Convertible Series C Preferred Stock: In October 2016, the Company sold 500 shares of Series C convertible preferred stock with a purchase price of $1,000 per share for gross proceeds of $500,000 to a healthcare investment fund under the Series C Preferred Stock Agreement. Each share of Series C Preferred Stock is convertible into 2,500 shares of common stock which results in an effective conversion price of $0.40 per common share. This resulted in the reduction of the conversion price of the Series B Preferred Stock to $0.40 and a reduction in the exercise price of the Series B warrants to $0.40. On December 29, 2016, as a result of the Series D Preferred Stock Agreement (as discussed below), the conversion price of the Series C Preferred Stock was reset to $0.25. As part of the terms of the Series C Preferred Stock Agreement, the Company entered into a Registration Rights Agreement with the purchaser to file a registration statement to register for resale the shares of common stock underlying the preferred shares within 30 days following the closing of the agreement. Each Preferred Stock is convertible into common stock at any time at the election of the investor. The terms of the Series C Convertible Preferred Stock are as follows:

The Series C Preferred Stock is considered to be contingently redeemable convertible and as a result, has been classified as mezzanine equity in the Company's balance sheet because the Most Favored Nation provision is a redemption feature that is outside the control of the Company.

At the date of the financing, because the effective conversion rate of the preferred stock was less than the market value of the Company’s common stock, a beneficial conversion feature of $325,000 has been recorded as a discount to the preferred stock and an increase to additional paid in capital. Because the preferred stock is perpetual, in October 2016, the Company fully amortized the discount related to the beneficial conversion feature on the deemed dividend in the consolidated statement of operations.

In December 2016, the Series C Preferred stockholder converted 39 shares of its preferred stock to common stock as allowed under the Series C Preferred Stock Agreement, resulting in the issuance of 97,500 shares of common stock at an effective price of $0.40 per share. On December 29, 2016, as a result of the signing of the Series D Preferred Stock Agreement (as discussed below), the conversion price of the Series B and Series C Preferred Stock was reset to $0.25. From the date of this reset to December 31, 2016, a Series C Stockholder converted 75 shares of their preferred stock to common stock, resulting in the issuance of 300,000 shares of common stock. For the three months ended March 31, 2017, the Series C stockholder converted 386 shares at a conversion rate of 4000:1 resulting in the issuance of 1,544,000 shares of common stock. As a result, all Series C Preferred Stock has been converted to common stock and there is no liquidation preference outstanding as of September 30, 2017.

In addition, as a result of the Series D financing and the adjustment in the conversion price, a beneficial conversion feature of $175,000 has been recorded as a discount to the preferred stock and an increase to additional paid in capital. Because the preferred stock is perpetual, in January 2017, the Company fully amortized the discount related to the beneficial conversion feature on the deemed dividend in the consolidated statement of operations.

Convertible Series D Preferred Stock: In January 2017, the Company sold 1,200 shares of Series D convertible preferred stock with a purchase price of $1,000 per share for gross proceeds of $1,200,000 to a healthcare investment fund and other private investors under the Series D Preferred Stock Agreement. Each share of Series D Preferred Stock is convertible into 4,000 shares of common stock which results in an effective conversion price of $0.25 per common share. This resulted in the reduction of the conversion price of the Series B and Series C Preferred Stock to $0.25 and a reduction in the exercise price of the Series B warrants to $0.25. As part of the terms of the Series D Preferred Stock Agreement, the Company entered into a Registration Rights Agreement with the purchasers to file a registration statement to register for resale the shares of common stock underlying the preferred shares within 30 days following the closing of the agreement. Each Preferred Stock is convertible into common stock at any time at the election of the investor. The terms of the Series D Convertible Preferred Stock are identical to those of the Series C Convertible Preferred Stock agreement discussed above with the exception of the conversion price which is $0.25 per common share.

The Series D stock has liquidation preference over common stock. In the event of any liquidation, dissolution or winding up of the Company, either voluntary or involuntary, Series D Preferred stockholders receive an amount per share equal to the conversion price of $0.25, subject to down-round adjustment, multiplied by the as-if converted share amount of 800,000 common shares, totaling $0.2 million as of September 30, 2017.

The Company also considered the classification of the Series D Preferred Stock Agreement, the Series D Preferred Stock is considered to be contingently redeemable convertible and as a result, has been classified as mezzanine equity in the Company's balance sheet because the Most Favored Nation provision is a redemption feature that is outside the control of the Company.

At the date of the financing, because the effective conversion rate of the preferred stock was less than the market value of the Company’s common stock, a beneficial conversion feature of $536,000 has been recorded as a discount to the preferred stock and an increase to additional paid in capital. Because the preferred stock is perpetual, in January 2017, the Company fully amortized the discount related to the beneficial conversion feature on the deemed dividend in the consolidated statement of operations.

For the three and nine months ended September 30, 2017, the Series D stockholders converted 0 and 1,000 shares, respectively, at a conversion rate of 4000:1 and a conversion price of $0.25 per share resulting in the issuance of 2,024,000 and 4,000,000 shares of common stock.

Pending Series E Preferred Stock: On May 3, 2017, the Company entered into a securities purchase agreement to sell 1,000,000 shares of a new Series E Preferred Stock, par value $0.001 per share, at a purchase price of $20.00 for each preferred share for aggregate gross proceeds of $20,000,000 (the “Series E Preferred Stock Financing”). The purchaser did not provide funding to close the transaction on July 10, 2017 as required under the securities purchase agreement. In connection with the signing of the securities purchase agreement, an affiliate of the purchaser entered into a financial guarantee to the benefit of the Company that provides for payment of the purchase price in full within 90 days of exercise. The Company exercised this guarantee on July 12, 2017 and the guarantor failed to honor the guarantee. The Company has subsequently filed a petition commencing arbitration as described in Note 8.

There are significant judgments and estimates inherent in the determination of the fair value of the Company's warrants. These judgments and estimates included the assumptions regarding its future operating performance, the time to completing a liquidity event and the determination of the appropriate valuation methods. If the Company had made different assumptions, its warrant valuation could have been significantly different.

Stock Option Plans: 2014 Omnibus Incentive Plan

The 2014 Omnibus Incentive Plan (the "2014 Plan") was adopted to provide a means by which officers, non-employee directors, and employees of and consultants to the Company and its affiliates could be given an opportunity to acquire an equity interest in the Company. All officers, non-employee directors, and employees of and consultants to the Company are eligible to participate in the 2014 Plan.

Options granted under the 2014 Plan expire no later than 10 years from the date of grant. Options granted under the 2014 Plan may be either incentive or non-qualified stock options. For incentive and non-qualified stock option grants, the option price shall be at least 100% of the fair value on the date of grants, as determined by the Company's Board of Directors. If at any time the Company grants an option, and the optionee directly or by attribution owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company, the option price shall be at least 110% of the fair value and shall not be exercisable more than five years after the date of grant.

The weighted-average remaining contractual term of options vested and exercisable at September 30, 2017 was approximately 7.14 years.

The aggregate intrinsic value is the sum of the amounts by which the quoted market price of the Company's stock exceeded the exercise price of the stock options at September 30, 2017 for those stock options for which the quoted market price was in excess of the exercise price ("in-the-money options").

In August 2015, in conjunction with the Series B Preferred Stock sale (discussed below), the Company raised $5.0 million at $1,000 per share resulting in the automatic conversion of the Series A Preferred Stock to common stock.

From the date of this reset to December 31, 2016, the Series C Stockholder converted 75 shares of their preferred stock to common, resulting in the issuance of 300,000 shares of common stock.

Preferred Stock

The Company has authorized 20,000,000 shares of preferred stock with a par value of $0.001 per share.

Series A Preferred Stock: In April 2015, the Company sold 250,000 shares of Series A Preferred Stock with par value of $0.001 and 50,000 warrants to purchase the Company's common stock for an aggregate purchase price of $625,000, or $2.50 per share to a group of private investors. The shares of preferred stock automatically convert to shares of common stock either at (i) a subsequent equity financing of at least $1,000,000 or (ii) October 1, 2015, whichever is earlier. The warrants are exercisable at a price of $5.00 per share and expire five years from the issuance date. In May 2015, the Company sold 150,000 shares and 30,000 warrants and in July 2015, the Company sold 180,000 shares and 36,000 warrants under the same terms and conditions.

The Series A Preferred Stock issued also has a "down-round" protection feature provided to the investors if the Company subsequently issues or sells any shares in a round of equity financing of at least $1,000,000 prior to October 1, 2015 in which the shares of common stock to be acquired are at a price less than $2.50 per share. The Company is required to issue additional shares of common stock to the investors in an amount such that the subscription price paid, when divided by the total number of shares issued will result in an actual price paid per share of common stock equal to such lower price. This conversion occurred as discussed above in conjunction with the Series B Preferred Stock financing totaling $5.0 million and resulted in the conversion of 580,000 shares of Series A Preferred Stock at to 1,812,500 shares of common stock.

Redeemable Convertible Series B Preferred Stock: In August 2015, the Company sold 5,000 shares of Series B Convertible Preferred Stock and warrants to purchase 6,250,000 shares of the Company's common stock for an aggregate purchase price of $1,000 per share resulting in gross proceeds of $5.0 million. Each share of preferred stock is convertible into 1,250 shares of common stock which results in an effective conversion price of $0.80 per common share and can be converted by the holder at any time. The Series B Preferred Stock issued also has a "down-round" protection feature provided to the investors if the Company subsequently issues or sell any shares of common stock, stock options, or convertible securities at a price less than the conversion price of $0.80 per common share. The conversion price is automatically adjusted down to the price of the instrument being issued. In October 2016, as a result of the Series C Preferred Stock Agreement (discussed below), the conversion price of the Series B Preferred Stock was reset to $0.40. On December 29, 2016, as a result of the Series D Preferred Stock Agreement (discussed in Note 8 below), the conversion price of the Series B Preferred Stock was reset to $0.25. The Series B shares have liquidation preference over other preferred shares and common stock and have voting rights equal to the number of common shares into which each holder's preferred stock is convertible as of the record date. The preferred stock has no dividend rights. If dividends are declared on the common stock, the holders of the preferred stock shall be entitled to participate in such dividends on an as-if converted basis. The warrants are exercisable at a price of $1.15 per share, subject to reset, and expire five years from the issuance date. See additional discussion regarding these warrants in Note 6 below.

In the event of any liquidation, dissolution or winding up of the Company, either voluntary or involuntary, Series B Preferred stockholders receive an amount per share equal to the conversion price of $0.80, subject to down-round adjustment, multiplied by the as-if converted share amount of 5,625,000 common shares, totaling $4.5 million. If upon the liquidation, the assets are insufficient to permit payments to the Series B holders, all assets legally available will be distributed in a pro rata basis among the Series B holders in proportion to the full amounts they would otherwise be entitled to receive. Any remaining assets are distributed pro rata among the common stockholders.

Subject to certain trigger events occurring, the Series B Preferred stock holders have the right to force the Company to redeem the shares of preferred stock at a price per preferred share equal to the greater of (A) 115% of the conversion amount and (B) the product of (1) the conversion rate in effect at such time and (2) the greatest closing sale price of the Common Stock during the period beginning on the date immediately preceding such triggering event and ending on the date such holder delivers the notice of redemption. Such triggering events include:

As certain of these triggering events are considered to be outside the control of the Company, the Series B Preferred Stock is considered to be contingently redeemable convertible and as a result, has been classified as mezzanine equity in the Company's balance sheet.

In December 2015, a Series B Preferred Stock holder converted 500 shares of its preferred stock to common stock at the conversion rate of 1,250:1 resulting in the issuance of 625,000 shares of common stock. In March 2016, another Series B Preferred stockholder converted 8 shares of its preferred stock to common stock at the same ratio resulting in the issuance of 10,000 shares of common stock. In October 2016, as a result of the Series C Preferred Stock Agreement (discussed below), the conversion price of the Series B Preferred Stock was reset to $0.40. From October 2016 to December 31, 2016, Series B Stockholders converted 461 shares of its preferred stock to common, at the conversion rate of 2,500:1 resulting in the issuance of 1,152,500 shares of common stock. As a result of these conversions, the liquidation preference for the Series B Preferred Stock has been reduced to $4.0 million as of December 31, 2016.

Convertible Series C Preferred Stock: In October 2016, the Company sold 500 shares of convertible preferred stock with a purchase price of $1,000 per share for gross proceeds of $500,000 to a healthcare investment fund under the Series C Preferred Stock Agreement. Each share of Preferred Stock is convertible into 2,500 shares of common stock which results in an effective conversion price of $0.40 per common share. This resulted in the reduction of the conversion price of the Series B Preferred Stock to $0.40 and a reduction in the exercise price of the Series B warrants to $0.40. As part of the terms of the Series C Preferred Stock Agreement, the Company entered into a Registration Rights Agreement with the purchaser to file a registration statement to register for resale the shares of common stock underlying the preferred shares within 30 days following the closing of the agreement. Each Preferred Stock is convertible into common stock at any time at the election of the investor. The terms of the Series C Convertible Preferred Stock are as follows:

The Company also considered the classification of the Series C Preferred Stock Agreement. Because the Most Favored Nation provision is a redemption feature that is outside the control of the Company, the Series C Preferred Stock is considered to be contingently redeemable convertible and as a result, has been classified as mezzanine equity in the Company's balance sheet.

At the date of the financing, because the effective conversion rate of the preferred stock was less than the market value of the Company’s common stock, a beneficial conversion feature of $325,000 has been recorded as a discount to the preferred stock and an increase to additional paid in capital. Because the preferred stock is perpetual, in October 2016, the Company fully amortized the discount related to the beneficial conversion feature on the deemed dividend in the consolidated statement of operations.

In December 2016, the Series C Preferred stockholder converted 39 shares of its preferred stock to common stock as allowed under the Series C Preferred Stock Agreement, resulting in the issuance of 97,500 shares of common stock at an effective price of $0.40 per share. On December 29, 2016, as a result of the signing of the Series D Preferred Stock Agreement (discussed in Note 8 below), the conversion price of the Series B and Series C Preferred Stock was reset to $0.25. From the date of this reset to December 31, 2016, the Series C Stockholder converted 75 shares of their preferred stock to common, resulting in the issuance of 300,000 shares of common stock.

There are significant judgments and estimates inherent in the determination of the fair value of the Company's warrants. These judgments and estimates included the assumptions regarding its future operating performance, the time to completing an IPO or other liquidity event and the determination of the appropriate valuation methods. If the Company had made different assumptions, its warrant valuation could have been significantly different.

Stock Option Plans: 2014 Omnibus Incentive Plan

The 2014 Omnibus Incentive Plan (the "2014 Plan") was adopted to provide a means by which officers, non-employee directors, and employees of and consultants to the Company and its affiliates could be given an opportunity to acquire an equity interest in the Company. All officers, non-employee directors, and employees of and consultants to the Company are eligible to participate in the 2014 Plan.

On October 31, 2014, after the closing of the Merger, our Board of Directors approved the 2014 Plan. The 2014 Plan reserved 3,200,000 shares for future grants. As of December 31, 2016, options (net of canceled or expired options) covering an aggregate of 1,142,500 shares of the Company's common stock had been granted under the 2014 Plan, and the Company had 1,142,500 options outstanding and 857,500 shares available for future grants under the 2014 Plan.

Options granted under the 2014 Plan expire no later than 10 years from the date of grant. Options granted under the 2014 Plan may be either incentive or non-qualified stock options. For incentive and non-qualified stock option grants, the option price shall be at least 100% of the fair value on the date of grants, as determined by the Company's Board of Directors. If at any time the Company grants an option, and the optionee directly or by attribution owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company, the option price shall be at least 110% of the fair value and shall not be exercisable more than five years after the date of grant.

Options granted under the 2014 Plan may be immediately exercisable if permitted in the specific grant approved by the Board of Directors and, if exercised early may be subject to repurchase provisions. The shares acquired generally vest over a period of five years from the date of grant. The Company granted options to purchase 1,142,500 shares net of cancellations through December 31, 2016, under the 2014 Plan.

The following is a summary of activity under the 2014 Plan as of December 31, 2016:  

The weighted-average remaining contractual term of options vested and exercisable at December 31, 2016 was approximately 7.9 years

Aggregate intrinsic value is the sum of the amounts by which the quoted market price of the Company's stock exceeded the exercise price of the stock options at December 31, 2016 for those stock options for which the quoted market price was in excess of the exercise price ("in-the-money options"). As of December 31, 2016, the aggregate intrinsic value of options outstanding was $0. As of December 31, 2016, 436,000 options to purchase shares of common stock were exercisable.

Restricted Stock Awards

Restricted stock awards ("RSAs") are granted to our board of directors and members of senior management and are issued pursuant to the Company's 2014 Omnibus Incentive Plan. On October 20, 2015, a total of 1,200,000 RSAs were granted to members of the Company's senior management and board of directors with a fair market value of approximately $900,000. These RSAs vest from one to three years from the grant date as services are rendered to the Company. For the years ended December 31, 2016 and 2015, the Company recorded $356,250 and $62,500, respectively, in stock-based compensation expense related to these awards. (See discussion below). The total amount of unrecognized compensation cost related to non-vested RSAs was $481,250 as of December 31, 2016.

Stock Based Compensation Expense

The Company recognizes stock-based compensation expense based on the fair value of that portion of stock options that are ultimately expected to vest during the period. Stock-based compensation expense recognized in the consolidated statements of operations includes compensation expense for stock-based awards based on the estimated grant date fair value over the requisite service period. For the years ended December 31, 2016 and 2015, the Company recognized stock-based compensation expense of $706,368 and $414,343 (including compensation expense for RSAs discussed above) which was recorded as a general and administrative expense in the consolidated statements of operations.

The total amount of unrecognized compensation cost related to non-vested stock options was $1,023,418 as of December 31, 2016. This amount will be recognized over a weighted average period of 2.9 years.

Valuation Assumptions

The fair value of options was estimated at the date of grant using the Black-Scholes option pricing model. Expected volatility is based on industry peers who are also in the early development stage given the limited market data available in the public arena. The expected term was estimated using the simplified method as permitted under SAB No. 110, since the Company has no recent exercise or forfeiture history that is representative of options granted during the year. The expected term represents the estimated period of time that stock options are expected to be outstanding, which is less than the contractual term which is generally ten years. The risk-free interest rate is based on the U.S. Treasury yield. The expected dividend yield is zero, as the Company does not anticipate paying dividends in the near future. There were no options granted in the year ended December 31, 2016; the assumptions for options granted in the year ended December 31, 2015 are as follows:
