Note 11 – Registered Direct Equity Offerings

In September 2016, the Company entered into securities purchase agreements with certain institutional investors for the sale of 13,333,334 shares of common stock at a purchase price of $0.75 per share in a registered direct equity offering (the “Registered Offering”), pursuant to a registration statement on Form S-3. The investors in this Registered Offering also received warrants to purchase 6,666,667 shares of common stock with an exercise price of $1.00 per share and a five-year term. The Company received net proceeds from the Registered Offering of approximately $9.0 million after placement fees of 8% of the gross proceeds and various expenses. In addition, the placement agent received warrants covering 1,066,667 shares (or 8% of total shares sold to investors) with a per share exercise price of $0.825 and a five-year term.

A summary of the cash proceeds of the Registered Offering is shown below:

As fully described in Note 5 above, the investor warrants and the placement agent warrants issued in conjunction with the Registered Offering are required to be accounted for in accordance with ASC 480 and ASC 815.

A summary of the ASC 480 allocation of the proceeds of the Registered Offering is as follows:

Closing costs included 1,066,667 warrants valued at $819,200 for placement agent fees. Based upon the estimated fair value of the stock and warrants in the units, the Company allocated $241,986 to financing expense and $577,214 as stock issuance costs.

On January 31, 2018, the Company entered into subscription agreements with certain investors who owned convertible promissory notes of the Company (the “Notes”) for the sale by the Company of 12,062,728 shares of common stock in a registered direct offering (the “January 31 Offering”). The investors in the January 31 Offering also received warrants to purchase 7,718,010 shares of common stock. The securities were sold at a combined purchase price of $0.50 per share of common stock and related warrants, for aggregate gross proceeds to the Company of approximately $6.0 million. The Notes matured on January 31, 2018, upon which date the Company became obligated to pay the principal amount of approximately $6.0 million on the Notes, plus accrued but unpaid interest of approximately $0.3 million, for aggregate payment obligations at maturity of approximately $6.3 million. The common stock and warrants were issued in full satisfaction of approximately $6.0 million of such payment obligations, with one holder of an aggregate principal amount and accrued unpaid interest of approximately $0.3 million electing to be repaid in cash instead of participating in the January 31, 2018 Offering. As a result, all of the proceeds from the January 31 Offering were used to satisfy the Company’s payment obligations pursuant to the Notes. The warrants will be exercisable for a period of five years commencing on their issuance date, at an exercise price of $0.75 per share of common stock, subject to certain ownership limitations and adjustments as provided under the terms of the warrants. The number of shares of common stock underlying the warrant issued to each investor was calculated as the difference between (x) the number of shares of common stock issued to each investor in the January 31, 2018 Offering in respect of the payment obligations relating solely to principal amounts on the Notes and (y) the number of shares of common stock underlying certain warrants originally issued to such investor in the original Notes offering. The effect was to bring each investor from 50% warrant coverage in the original offering of Notes, assuming conversion of the principal amount thereof at an original conversion price of $0.75 per share, to 100% warrant coverage after the January 31 Offering, assuming reinvestment of the principal amount on the Notes at $0.50 per share. The warrants in the January 31 Offering, had an original exercise price of $1.00 per share, therefore, due to the reduction of exercise price to $0.75 per share, the Company recognized a non-cash inducement interest expense of approximately $2.4 million due to the modification. In connection with this January 31 Offering, the Company paid a commission of $164,425 to the placement agent.

On June 15, 2018, the Company entered into subscription agreements with certain investors for the sale of 1,970,000 shares of common stock at a purchase price of $0.50 per shares in a registered direct offering, pursuant to a registration statement on Form S-3. The investors in the offering also received warrants to purchase 1,970,000 shares of common stock with an exercise price of $0.75 per share and a five-year term. The Company received net proceeds from the offering of approximately $0.9 million. In addition, the placement agent received warrants covering 133,600 shares of common stock (or 8% of total shares sold to investors) with a per share exercise price of $0.55, a five-year term and include a cashless exercise provision.
