Item 4 of the prior Schedule 13D is amended and supplemented by adding the information below:

Closing of Private Placement; Cancellation of Commitment Warrants

On February 19, 2019, the Issuer obtained the Stockholder Approval and filed the Certificate of Designations with the Secretary of the State of Delaware, and on February 20, 2019, the Issuer filed an Amended and Restated Certificate of Designations, Preferences and Rights of Series A Convertible Preferred Stock (the “Amended and Restated Certificate of Designation”) with the Secretary of the State of Delaware. The Amended and Restated Certificate of Designation sets forth the rights, powers and preferences of the Series A Preferred Stock and was filed prior to the issuance of any Series A Preferred Stock in order to reflect a change in required ownership for certain board representation and related governance rights from a number of shares to an equivalent percentage of outstanding shares. Subsequently, on February 20, 2019, the Private Placement closed, with 13,565 and 1,435 shares of Series A Preferred Stock being issued to PWIMF and PWPI, respectively. As a result of the Stockholder Approval, the Commitment Warrants are not exercisable and have been surrendered by the PW Funds to the Issuer for cancellation.

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 8,749,173 shares of Common Stock outstanding as of January 8, 2019, as reported in the Issuer’s definitive proxy statement filed with the SEC on January 10, 2019.

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 and warrants to purchase up to 902,528 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 and warrants to purchase up to 115,653 shares of Common Stock. The Series A Preferred Stock contains 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, for purposes of Reg. Section 240.13d-3, 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 the Series A Preferred Stock, held in the aggregate by the PW Funds, for an aggregate beneficial ownership percentage of approximately 16.8% 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 and the Series A Preferred Stock, for an aggregate beneficial ownership percentage of approximately 15.2% of the shares of Common Stock deemed issued and outstanding as of the filing date of this report.

Each of Mr. Park and PWAM has shared power to vote or direct the vote of 1,473,218 shares of Common Stock. Each of Mr. Park and PWAM has shared power to dispose or direct the disposition of 1,473,218 shares of Common Stock.

PWIMF has shared power to vote or direct the vote of 1,332,191 shares of Common Stock. PWIMF has shared power to dispose or direct the disposition of 1,332,191 shares of Common Stock.

Each of PWAM and Mr. Park specifically disclaims beneficial ownership in the shares of Common Stock reported herein except to the extent of their pecuniary interest therein, and this report shall not be deemed an admission that any such person is the beneficial owner of these securities for purposes of Section 16 of the U.S. Securities Exchange Act of 1934, as amended, or for any other purpose.
