[1] Under the terms of certain outstanding warrants, the holders may elect to exercise the warrants under a cashless exercise feature. The shares listed, represent the shares holders could exercise cashless as of September 30, 2017. If we register for resale the shares subject to warrants, the holders of some of the warrants may no longer have the right to elect a cashless exercise. Should we fail to maintain a registration statement for the resale of shares under certain other warrant, the shares under those warrants may be exercisable using a cashless exercise feature.

[2] Includes one warrant which contains full ratchet anti-dilution provisions and is classified as derivative warrant liabilities in our balance sheet. Under the anti-dilution clause contained in this warrant, in the event of equity issuances (i.e. issuances of our common stock, certain awards of stock options to employees, and issuances of warrants and/or other convertible instruments) at prices below the exercise price of this warrant, we are required to lower the exercise price on this warrant and increase the number of shares underlying this warrant.

[3] Includes a warrant to purchase of 300,000 shares of our common stock which contains a most favored nations anti-dilution provision. Under that provision, in the event we issue warrants and/or other convertible instruments with anti-dilution provisions with respect to the exercise price of the warrant or the conversion price of the convertible instrument, we will be required to provide the same anti-dilution provision in this warrant and may be required to lower the exercise price on this warrant and/or increase the number of shares underlying this warrant.

[4] The warrants were classified as derivative warrant liabilities in our balance sheets due to the Share Sequencing as of December 31, 2016, and were reclassified to equity (deficit) effective March 31, 2017.
