Series B Purchase Agreement; Closing of Series B Private Placement; Cancellation of Series Commitment Warrants

On May 15, 2020, the Issuer issued, pursuant to a Purchase Agreement (the “Series B Purchase Agreement”) with the PW Funds, 6,000 shares of Series B Convertible Preferred Stock, par value $0.001 per share (the “Series B Preferred Stock”), including 5,450 and 550 shares of Series B Preferred Stock to PWIMF and PWPI, respectively, at a price of $1,000 per share, for an aggregate purchase price of $6,000,000 (the “Series B Private Placement”). The closing of the Series B Private Placement was contingent on the Issuer obtaining stockholder approval of the issuance of more than 20% of the Common Stock pursuant to the Series B Private Placement for purposes of Nasdaq Listing Rule 5635 (the “Series B Stockholder Approval”), which occurred at a special meeting of stockholders convened for such purpose on May 15, 2020. The terms, rights, obligations and preferences of the Series B Preferred Stock are set forth in the Certificate of Designations, Preferences and Rights of Series B Convertible Preferred Stock of the Issuer (the “Series B Certificate of Designations”), filed with the Secretary of State of the State of Delaware on May 15, 2020. A copy of the form of Series B Certificate of Designations is incorporated by reference as Exhibit F to this Schedule 13D. The terms and provisions of the Series B Preferred Stock and the Series B Certificate of Designations are described more fully in the Issuer’s current report on Form 8-K filed with the Commission on March 13, 2020.

Pursuant to the Series B Purchase Agreement, the Issuer had also previously issued warrants to purchase an aggregate of 200,250 shares of the Common Stock (the “Series B Commitment Warrants”) to the PW Funds, including 181,850 and 18,400 to PWIMF and PWPI, respectively, exercisable at a price of $3.50 per share, subject to adjustment; provided, however, that the Series B Commitment Warrants would only vest and become exercisable in the event that the Issuer did not obtain the Series B Stockholder Approval on or prior to July 31, 2020. As a result of the Series B Stockholder Approval, on May 15, 2020, the Series B Commitment Warrants expired unvested and have been surrendered by the PW Funds to the Issuer for cancellation.

Interest in Securities of the Issuer.

Item 5 of the prior Schedule 13D is hereby amended and restated in its entirety to read as follows:

The aggregate percentage of Common Stock reported owned by each person named herein is based upon 9,156,260 shares of Common Stock outstanding as of May 12, 2020, as reported in the Issuer’s Quarterly Report on Form 10-Q filed with the SEC on May 15, 2020.

As of the filing date of this report, (i) PWIMF held 1,332,191 shares of Common Stock and, subject to the limitations described below, 13,565 shares of Series A Preferred Stock, convertible into 5,217,307 shares of Common Stock, warrants to purchase up to 902,528 shares of Common Stock, and 5,450 shares of Series B Preferred stock, convertible into 1,758,064 shares of Common Stock; and (ii) PWPI held 141,027 shares of Common Stock and, subject to the limitations described below, 1,435 shares of Series A Preferred Stock, convertible into 551,923 shares of Common Stock, warrants to purchase up to 115,653 shares of Common Stock, and 550 shares of Series B Preferred stock, convertible into 177,419 shares of Common Stock. Each of the Series A Preferred Stock and Series B Preferred Stock contain a provision prohibiting conversion to the extent that the holder, together with its affiliates, would beneficially own in excess of 9.9% of the number of shares of Common Stock outstanding immediately after giving effect to such conversion. The warrants expire on June 14, 2027 and contain a provision prohibiting exercise to the extent that the holder, together with its affiliates, would beneficially own in excess of 9.99% of the number of shares of Common Stock outstanding immediately after giving effect to such exercise.

As a result of the foregoing, PWAM and Mr. Park may be deemed to beneficially own 1,473,218 shares of Common Stock, and no shares of Common Stock underlying the warrants and each of the Series A Preferred Stock and Series B Preferred Stock, held in the aggregate by the PW Funds, for an aggregate beneficial ownership percentage of approximately 16.1% of the shares of Common Stock deemed issued and outstanding as of the filing date of this report; and PWIMF may be deemed to beneficially own 1,332,191 shares of Common Stock, and no shares of Common Stock underlying the warrants, the Series A Preferred Stock and the Series B Preferred Stock, for an aggregate beneficial ownership percentage of approximately 14.5% of the shares of Common Stock deemed issued and outstanding as of the filing date of this report.
