Pursuant to Warrant Amendment Agreements that were entered into with each of the Medalist Funds, with respect to the Series F Warrants and Series G Warrants, if the exercise of an original warrant at the Reduced Exercise Price (as such term is defined in the Warrant Amendment Agreements) would cause each of the Medalist Funds to exceed the Beneficial Ownership Limitation, in lieu of receiving such number of shares of common stock in excess of the Beneficial Ownership Limitation, the Company will only issue such number of shares of common stock to each of the Medalist Funds as would not cause each of the Medalist Funds to exceed the maximum number of shares of common stock permitted under the Beneficial Ownership Limitation, and each of the Medalist Funds shall be issued, at an exercise price equal to the Reduced Exercise Price less $15.80 per share, pre-funded common stock purchase warrants covering such number of shares of common stock as would otherwise have been in excess of the Beneficial Ownership Limitation. In connection with such exercises, the Medalist Funds were issued pre-funded common stock purchase warrants to purchase an aggregate of 20,719 shares of common stock. The Company received aggregate gross proceeds of approximately $327,000 in connection with the purchase of such pre-funded common stock purchase warrants.

On November 4, 2019, the Company entered into a Settlement Agreement with the Medalist Funds, pursuant to which the Company agreed to pay the Medalist Funds an aggregate of $47,223, in cash, in order to compensate the Medalist Funds for the difference between the Amended Exercise Price (as such term is defined in such Settlement Agreement) and the lower priced shares of common stock that were offered to investors in connection with the Company’s October 2019 registered direct offering pursuant to which it issued 125,000 shares of common stock to certain institutional investors at an offering price of $14.00 per share.
