Explanation of Responses:
(1)	The original Form 4 Report filed on September 27, 2017 inadvertently omitted the amendment and exercise of an additional warrant.
(2)	On September 25, 2017, the Issuer completed the initial closing of a tender offer in which the Issuer offered to amend the terms of the outstanding warrants the Issuer issued to investors participating in private placement financings the Issuer completed on August 29, 2014 (the "2014 Warrants"), on November 23, 2015 (the "2015 Warrants") and on January 23, 2017 (the "2017 Warrants"). As part of the tender offer and in order to raise funds to support its continued operations, the Issuer offered to reduce the respective exercise prices of the 2014, 2015 and 2017 Warrants if the holders agreed to exercise their Warrants in cash by September 25, 2017. The Reporting Person holds a 2015 Warrant and elected to participate in the Issuer's tender offer. As a result, the exercise price and the expiration date, among other terms, of the 2015 Warrant held by the Reporting Person were amended.
(3)	In accordance with the terms of the Issuer's tender offer, the Reporting Person exercised his 2015 Warrant in full and in cash on September 25, 2017.
