Explanation of Responses:

( 1 )Pursuant to a stock pledge agreement between the Reporting Person and an unaffiliated third party (the "Pledgee"), dated on or about July, 2018, as amended (the "Pledge Agreement"), the Reporting Person secured a promissory note by a pledge of 25,000 shares of common stock of the Issuer (the "Shares"). On January 28, 2020, the Reporting Person ceased to be a 10% owner of shares of common stock of the Issuer. Thereafter, in April of 2020, the Pledgee exercised its right under the Pledge Agreement and transferred the entirety of the Shares as full and final satisfaction of the $192,505 outstanding principal amount due under the promissory note. Accordingly, although this Form 4 is being filed to report such transfer from the Reporting Person, the transfer occurred after the Reporting Person ceased to be a 10% owner of shares of common stock of the Issuer. ( 2 )The total number of shares reported contains a de minimis correction to the balance on the Reporting Person's Form 3 previously filed on September 19, 2017.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
