The Company designated up to 30,000 shares of Series H-4 Stock and each share has a stated value of $235.50 (the “Stated Value”). Each share of Series H-4 Stock is convertible at any time at the option of the holder thereof, into a number of shares of Common Stock determined by dividing the Stated Value by the initial conversion price of $14.15 per share, subject to a 9.99% blocker provision. The Series H-4 Stock has the same dividend rights as the Common Stock, and no voting rights except as provided for in the Certificate of Designation or as otherwise required by law. In the event of any liquidation or dissolution of the Company, the Series H-4 Stock ranks senior to the Common Stock in the distribution of assets, to the extent legally available for distribution.

In response to the request, on September 10, 2018, the Company filed a Certificate of Amendment (the “COD Amendment”) to the Certificate of Designation to provide for stockholder approval as described above prior to the conversion of the Series H-4 Shares.

Warrants

Warrant Exchange

On April 19, 2018, the Company entered into separate Warrant Exchange Agreements (the “Exchange Agreements”) with the holders (the “Merger Warrant Holders”) of existing warrants issued in the Reverse Merger (the “Merger Warrants”) to purchase shares of Common Stock, pursuant to which, on the closing date, the Merger Warrant Holders exchanged each Merger Warrant for 1/18 of a share of Common Stock and 1/12 of a warrant to purchase a share of Common Stock (collectively, the “Series I Warrants”). The Series I Warrants have an exercise price of $13.80 per share. In connection with the Exchange Agreements, the Company issued an aggregate of (i) 48,786 new shares of common stock and (ii) Series I Warrants to purchase an aggregate of 73,178 shares of common stock. The Company valued the (a) stock and warrants issued in the amount of $972,368, (b) the warrants retired in the amount of $655,507, and (c) recorded the difference as deemed dividend in the amount of $316,861. The warrants were valued using the Black-Scholes option-pricing model on the date of the exchange using the following assumptions: (a) fair value of common stock $10.32, (b) expected volatility of 103% and 110%, (c) dividend yield of $0, (d) risk-free interest rate of 2.76% and 2.94%, (e) expected life of 3 years and 4.13 years.

Exercise of Series H-4 Warrants and Issuance of Series J Warrants

On August 31, 2018, the Company offered (the “Repricing Offer Letter”) to the holders (the “Holders”) of the Company’s outstanding Series H-4 Warrants to purchase common stock of the Company issued on March 8, 2018 (the “Series H-4 Warrants”) the opportunity to exercise such Series H-4 Warrants for cash at a reduced exercise price of $3.60 per share (the “Reduced Exercise Price”) provided such Series H-4 Warrants were exercised for cash on or before September 4, 2018 (the “End Date”). In addition, the Company issued a “reload” warrant (the “Series J Warrants”) to each Holder who exercised their Series H-4 Warrants prior to the End Date, covering one share for each Series H-4 Warrant exercised during that period. The terms of the Series J Warrants are substantially identical to the terms of the Series H-4 Warrants except that (i) the exercise price is equal to $6.00, (ii) the Series J Warrants may be exercised at all times beginning on the 6-month anniversary of the issuance date on a cash basis and also on a cashless basis, (iii) the Series J Warrants do not contain any provisions for anti-dilution adjustment and (iv) the Company has the right to require the Holders to exercise all or any portion of the Series J Warrants still unexercised for a cash exercise if the VWAP (as defined in the Series J Warrant) for the Company’s common stock equals or exceeds $9.00 for not less than ten consecutive trading days.

On September 4, 2018, the Company received executed Repricing Offer Letters from a majority of the Holders, which resulted in the issuance of 260,116 shares of the Company’s common stock and Series J Warrants to purchase up to 260,116 shares of the Company’s common stock. The Company received gross proceeds of approximately $936,000 from the exercise of the Series H-4 Warrants pursuant to the terms of the Repricing Offer Letter.

On September 5, 2018, the Company received a request from Nasdaq to amend our Series H-4 Warrants to provide that the Series H-4 Warrants may not be exercised until the Company has obtained stockholder approval of the issuance of Common Stock underlying the Series H-4 Warrants pursuant to the applicable rules and regulations of Nasdaq. In response to the request, on September 10, 2018, the Company entered into an amendment (the “Warrant Amendment”) with the holders of the Series H-4 Stock to provide for stockholder approval as described above prior to the exercise of the Series H-4 Warrants.

The Company considers the warrant amendment for the Reduced Exercise Price and issuance of the Series J Warrants to be of an equity nature as the amendment and issuance allowed the warrant holders to exercise warrants and receive a share of Common Stock and warrant which, represents an equity for equity exchange. Therefore, the change in the fair value before and after the modification and the fair value of the Series J warrants will be treated as a deemed dividend in the amount of $1,019,040. The cash received upon exercise in excess of par is accounted through additional paid in capital.

The Company valued the deemed dividend as the sum of: (a) the difference between the fair value of the modified award and the fair value of the original award at the time of modification of $129,476, and (b) the fair value of the Series J Warrants in the amount of $889,564. The warrants were valued using the Black-Scholes option-pricing model on the date of the modification and issuance using the following assumptions: (a) fair value of common stock $3.90, (b) expected volatility of 144.3%, (c) dividend yield of $0, (d) risk-free interest rate of 2.77% and 2.78%, (e) expected life of 4.51 years and 5 years.

At the March 8, 2018 closing, the Company issued Series H-4 Warrants that entitled the holders to purchase, in aggregate, up to 447,383 shares of its common stock. As referenced above, on September 4, 2018, the Company received executed Repricing Offer Letters from a majority of the investors resulting in the exercise of Series H-4 Warrants to purchase 260,1161,560,696 shares of common stock. The Series H-4 Warrants were initially exercisable at an exercise price equal to $15.60 per share, which is now subject to adjustment at a reduced exercise price of $3.60 per share pending stockholder approval as proposed in the Company’s Notice of 2018 Annual Meeting of Stockholders. If this proposal is approved by the stockholders, the exercise price of the remaining Series H-4 Warrants will be reduced to $3.60 per share which will entitle the holders of the remaining Series H-4 Warrants to purchase, in aggregate, up to 187,117 additional shares of common stock.

A summary of the Company’s warrants to purchase common stock activity is as follows:

The warrants expire through the years 2020-2024.
