Explanation of Responses:

( 1 )On April 21, 2020, the reporting person exchanged an outstanding promissory note of the issuer for shares of common stock at $1.43 per share pursuant to an exchange agreement. The parties subsequently discovered a calculation error under which an additional $143,574 in interest should have been included in the balance of the exchanged note as of April 21, 2020, and the additional shares reported herein were issued on account of such additional interest. ( 2 )This form is being amended to correct the transaction code to an "A" to reflect that the transaction between the Issuer and Officer (at the time) is exempt under Rule 16b-3(d).

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

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
