Immediately following the execution of the subscription agreement with the Issuer on June 20, 2017 (the “Subscription Agreement”) (as disclosed in the Form 8-K filed by the Issuer with the Securities and Exchange Commission on June 20, 2017), each of the Reporting Persons may have been deemed to have beneficial ownership of 304,898 shares of Common Stock, which consisted of (i) 295,000 shares of Common Stock that were to be issued to Intracoastal at the closing of the transaction contemplated by the Subscription Agreement and (ii) 9,898 shares of Common Stock issuable upon exercise of a warrant that was to be issued to Intracoastal at the closing of the transaction contemplated by the Subscription Agreement (the “Intracoastal Warrant”), and all such shares of Common Stock in the aggregate represented beneficial ownership of approximately 9.99% of the Common Stock, based on (1) 2,747,140 shares of Common Stock outstanding as of June 19, 2017 as reported by the Issuer, plus (2) 295,000 shares of Common Stock that were to be issued to Intracoastal at the closing of the transaction contemplated by the Subscription Agreement and (3) 9,898 shares of Common Stock issuable upon exercise of the Intracoastal Warrant. The foregoing excludes 727,602 shares of Common Stock issuable upon exercise of the Intracoastal Warrant because the Intracoastal Warrant contains a blocker provision under which the holder thereof does not have the right to exercise the Intracoastal Warrant to the extent that such exercise would result in beneficial ownership by the holder thereof, together with the holder’s affiliates, and any other persons acting as a group together with the holder or any of the holder’s affiliates, of more than 9.99% of the Common Stock. Without such blocker provision, each of the Reporting Persons may have been deemed to have beneficial ownership of 1,032,500 shares of Common Stock.

(ii) As of the close of business on June 29, 2017, each of the Reporting Persons may have been deemed to have beneficial ownership of 561,674 shares of Common Stock, which consisted of (i) 281,450 shares of Common Stock held by Intracoastal and (ii) 280,224 shares of Common Stock issuable upon exercise of the Intracoastal Warrant, and all such shares of Common Stock in the aggregate represent beneficial ownership of approximately 9.99% of the Common Stock, based on (1) 2,747,140 shares of Common Stock outstanding as of June 19, 2017 as reported by the Issuer, plus (2) 2,595,000 shares of Common Stock in the aggregate issued at the closing of the transaction contemplated by the Subscription Agreement and (3) 280,224 shares of Common Stock issuable upon exercise of the Intracoastal Warrant. The foregoing excludes 457,276 shares of Common Stock issuable upon exercise of the Intracoastal Warrant because the Intracoastal Warrant contains a blocker provision under which the holder thereof does not have the right to exercise the Intracoastal Warrant to the extent that such exercise would result in beneficial ownership by the holder thereof, together with the holder’s affiliates, and any other persons acting as a group together with the holder or any of the holder’s affiliates, of more than 9.99% of the Common Stock. Without such blocker provision, each of the Reporting Persons may have been deemed to have beneficial ownership of 1,018,950 shares of Common Stock.
