[1] The 125,000 Series A-1 Warrants, at the election of the holder, may be exchanged for five Series W Warrants or four Series X-1 Warrants under the terms of the Series A-1 Warrant agreement. The Series W Warrants issued in exchange for the Series A-1 Warrants would be exercisable upon their issuance. The Series X-1 Warrants issued upon the exchange of the Series A-1 Warrants are exercisable commencing on the first trading day following October 31, 2018, and are therefore not exercisable for shares of common stock at September 30, 2017, and would not result in common stock equivalent incremental shares for purposes of diluted weighted average shares outstanding at such date. At September 30, 2017, no Series A-1 Warrants had been exchanged for Series W Warrants or Series X1 Warrants.

[2] The 422,838 shares of Series A Convertible Preferred Stock, at the election of the holder, if-converted into a number of shares of common stock at a conversion ratio equal to its $6.00 per share stated value divided by a conversion price of $4.99 per share, with such conversion price subject to further reduction, would result in 508,422 incremental shares of newly-issued common stock at September 30, 2017.

[3] The 422,838 Series A Warrants, at the election of the holder, may be exchanged for four Series X Warrants under the terms of the Series A Warrant agreement. The Series X Warrants issued in exchange for the Series A Warrants are exercisable commencing on the first trading day following October 31, 2018, and are therefore not exercisable for shares of common stock at September 30, 2017, and would not result in common stock equivalent incremental shares for purposes of diluted weighted average shares outstanding at such date. At September 30, 2017, no Series A Warrants had been exchanged for Series X Warrants.

[4] The 125,000 shares of Series A-1 Convertible Preferred Stock, at the election of the holder, if-converted into a number of shares of common stock at a conversion ratio equal to its $4.00 per share stated value divided by a conversion price of $4.00 per share, with such conversion price not subject to further adjustment, would result in 125,000 incremental shares of newly-issued common stock at September 30, 2017.
