March 2019 LOC Warrant

In March 2019, in consideration of a letter of credit cancelation related to the Company’s office lease, the Company issued a warrant to purchase warrant shares equal to a fixed principal amount divided by a variable exercise price. The warrants were initially classified as liabilities pursuant to ASC 480-10 due to their debt-like nature. On July 23, 2019, upon the exercise price of the warrants becoming fixed, the warrants became exercisable into 45,750 shares of the Company’s common stock and were reclassified to additional paid-in-capital with a fair value of $71,000.

2019 Bridge Note Warrants

Between March 18, 2019 and June 26, 2019, concurrent to the Company entering into Promissory Notes of $5,050,000, the Company issued twenty-one warrants to purchase warrant shares equal to a fixed principal amount divided by a variable exercise price. The warrants for all twenty-one Bridge Notes were initially liability classified pursuant to ASC 480-10 due to their debt-like nature. On July 23, 2019, upon the exercise price of the warrants becoming fixed, the warrants became exercisable into 2,781,250 shares of the Company’s common stock and were reclassified to additional paid-in-capital with a fair value of $4,259,000.

February 2020 Modification of Certain 2019 Bridge Note Warrants

In February 2020, the Company entered into a warrant exercise agreement with a holder of its Bridge warrants, pursuant to which the holder agreed to exercise 250,000 Bridge warrants in consideration of the Company lowering the exercise price of the 250,000 warrants from $2.00 to $0.692. Upon exercise of the warrants, the Company received cash proceeds of $173,000 and in turn issued 250,000 common shares. It is the Company’s policy to determine the impact of modifications to equity-classified warrants by analogy to the share-based compensation guidance per ASC 718, Compensation – Stock Compensation. Pursuant to that guidance, and due to the modification being applicable only to a single holder of the Bridge warrants, the incremental increase of $7,000 in fair value of the modified warrants was recorded as an expense in the condensed consolidated statement of operations for the three months ended March 31, 2020.

July 2019 Series 1 Warrants

In July 2019, the Company entered into an underwriting agreement, relating to a public offering, which was comprised of (1) 2,886,500 Class A Units, priced at $2.00 per unit, with each unit consisting of (i) one share of the Company’s voting common stock, (ii) one Series 1 warrant to purchase one share of Common Stock, and (iii) one Series 2 warrant to purchase one share of Common Stock, and (2) 10,787 Class B Units, priced at a price of $1,000 per unit, with each unit consisting of (i) one share of Series B convertible preferred stock, convertible into 500 shares of Common Stock, (ii) 500 Series 1 Warrants and (iii) 500 Series 2 Warrants.

The Series 1 Warrants had an exercise price of $2.00 and expire on the earlier of (a) 5 years from the date of issuance and (b) 30 calendar days following the public announcement of Positive Interim Results related to the diarrhea results from the HALT-D investigator initiated trial, if and only if certain trading benchmarks are achieved during such 30 calendar day period.

In the offering, the Company sold (i) 2,886,500 Class A Units, which included Series 1 warrants to purchase 2,886,500 shares of the Company’s common stock and (ii) 10,787 Class B Units, which included Series 1 warrants to purchase 5,393,500 shares of the Company’s common stock. In total, 8,280,000 Series 1 warrants were issued, with an initial valuation of $5,025,000 computed using the Black-Scholes-Merton pricing model using a stock price of $1.73, a strike price of $2.00, an expected term of 5.0 years, volatility of 109.25% and a risk-free discount rate of 1.83%. Upon issuance, the Series 1 warrants were classified in additional paid-in-capital.

September 2019 Modification of the July 2019 Series 1 Warrants

In September 2019, the Company reduced the exercise price all 8,280,000 Series 1 Warrants from $2.00 to $1.40. The Company determined the impact of this modification to be an increase in the fair value of the warrants of $522,000. Because the modification applied to the entire class of Series 1 Warrant holders, the increase in fair value represented a deemed dividend to the entire class of Series 1 Warrant holders. The modification did not result in the reclassification of the equity-classified Series 1 warrants from additional paid-in-capital to liability classification.

February 2020 Modification of the July 2019 Series 1 Warrants

Upon exercise of the warrants, the Company received cash proceeds of $144,000 and in turn issued 208,022 common shares. It is the Company’s policy to determine the impact of modifications to equity-classified warrants by analogy to share-based compensation guidance per ASC 718, Compensation – Stock Compensation. Pursuant to that guidance, and due to the modification being applicable only to a single holder of the Series 1 Warrants, the incremental increase of $6,413 in fair value of the modified warrants was recorded as an expense in the condensed consolidated statement of operations for the three months ended March 31, 2020.

July 2019 Series 2 Warrants

The Series 2 Warrants have an exercise price of $2.00 and expire on the first date on the earlier of (a) 5 years from the date of issuance and (b) 30 calendar days following the public announcement by the Company that a pivotal phase 3 clinical trial using crofelemer (Mytesi, or the same or similar product with a different name) for the treatment of cancer therapy-related diarrhea in humans has met its primary endpoint in accordance with the protocol, if and only if certain trading benchmarks are achieved during such 30 calendar day period.

In the July 2019 offering, the Company sold (i) 2,886,500 Class A Units, which included Series 2 warrants to purchase 2,886,500 shares of the Company’s common stock and (ii) 10,787 Class B Units, which included Series 2 warrants to purchase 5,393,500 shares (10,787 Class B Units multiplied by 500 warrants per Class B Unit equals 5,393,500) of the Company’s common stock. In total, 8,280,000 Series 2 warrants were issued, with an initial valuation of $5,026,000 computed using the Black-Scholes-Merton pricing model using a stock price of $1.73, a strike price of $2.00, an expected term of 5.0 years, volatility of 109.25% and a risk-free discount rate of 1.83%. Upon issuance, the Series 2 Warrants were classified in additional paid-in-capital.

March 5, 2020 Modification of the July 2019 Series 2 Warrants

On March 5, 2020, the Company entered into a warrant exercise agreement with a holder of its Series 2 Warrants, pursuant to which the holder agreed to exercise 90,940 Series 2 Warrants in consideration of the Company lowering the exercise price of the 90,940 warrants from $2.00 to $0.6050. Upon exercise of the warrants, the Company received cash proceeds of $55,000 and in turn issued 90,940 common shares. It is the Company’s policy to determine the impact of modifications to equity-classified warrants by analogy to share-based compensation guidance per ASC 718, Compensation – Stock Compensation. Pursuant to that guidance, and due to the modification being applicable only to a single holder of the Series 2 Warrants, the incremental increase of $6,000 in fair value of the modified warrants was recorded as an expense in the condensed consolidated statement of operations for the three months ended March 31, 2020.

March 23, 2020 Modification of the July 2019 Series 2 Warrants

On March 23, 2020, the Company entered into a Warrant Exercise and Preferred Stock Amendment Agreement (see Note 9) with a holder of its Series 2 Warrants, pursuant to which the holder agreed to exercise in cash its Series 2 Warrants to purchase an aggregate of 1,250,000 shares of Common Stock, in consideration of the Company reducing the Series 2 Warrant exercise price from $2.00 to $0.5227 per share, for gross proceeds to the Company of approximately $653,000, or $628,000 net of $25,000 of issuance costs. The Company determined the impact of this modification to be an increase in the fair value of the warrants of $65,000. Because the modification applied to a sole holder of Series 2 Warrants, the $65,000 increase in fair value was recorded as an expense in the condensed consolidated statement of operations for the three months ended March 31, 2020. The modification did not result in the reclassification of the equity-classified Series 1 Warrants from additional paid-in-capital to liability classification, and as of March 31, 2020, all 8,280,000 Series 2 Warrants have been exercised.

December 2019 PIPE Financing Warrants

In December 2019, the Company entered into a securities purchase agreement with certain investors pursuant to which the Company, in a Private Placement, sold (i) an aggregate of 2,500,000 unregistered shares of the Company’s common stock, and (ii) Warrants to purchase up to an aggregate of approximately 1,250,000 shares of common stock, for an aggregate purchase price of $1,500,000 (see Note 10). The warrants have an exercise price of $0.78 per share and become exercisable on June 24, 2020 (6 months after their issuance date) and have a five-year term.

The warrants were valued at $686,000 using the Black-Scholes option pricing model as follows: exercise price of $0.78 per share, stock price of $0.62 per share, expected life of five years, volatility of 143%, and a risk-free rate of 2.42%. As the common stock and warrants were issued in a unit structure, the aggregate proceeds of $1,500,000 were allocated to the two securities using the relative fair value method, resulting with the common stock and warrants being allocated $1,035,000 and $465,000, respectively. The warrants were classified in stockholders’ equity.
