Item 4. Ownership

   Provide the following information regarding the aggregate number and percentage of the class of securities of the issuer identified in Item 1.

(a) Amount Beneficially Owned:

   As of the close of business on December 29, 2020, the reporting persons and affiliates of the reporting persons beneficially owned an aggregate of 2,953,350 shares of the Issuer’s Common Stock as a result of holding 1,407,002 shares of the Issuer’s Common Stock and warrants to purchase 1,546,348 shares of the Issuer’s Common Stock or 5.8% of the Issuer’s Common Stock outstanding.

   Thereafter as of the close of business on January 6, 2021:

   i) Riverview Group LLC, a Delaware limited liability company ("Riverview Group"), beneficially owned 1,725,000 shares of the Issuer’s Common Stock as a result of holding warrants to purchase 1,725,000 shares of the Issuer’s Common Stock;

   ii) Integrated Assets II LLC, a Cayman Islands limited liability company ("Integrated Assets II"), beneficially owned 11,657 shares of the Issuer’s Common Stock; and

   iii) Integrated Assets, Ltd., an exempted company organized under the laws of the Cayman Islands ("Integrated Assets"), beneficially owned 24,937 shares of the Issuer’s Common Stock, which together with the shares of the Issuer’s Common Stock beneficially owned by Riverview Group and Integrated Assets II represented 1,761,594 shares of the Issuer’s Common Stock or 3.4% of the Issuer’s Common Stock outstanding.

   Millennium International Management LP, a Delaware limited partnership ("Millennium International Management"), is the investment manager to Integrated Assets II and Integrated Assets and may be deemed to have shared voting control and investment discretion over securities owned by Integrated Assets II and Integrated Assets.

   Millennium Management LLC, a Delaware limited liability company ("Millennium Management"), is the general partner of the managing member of Riverview Group and may be deemed to have shared voting control and investment discretion over securities owned by Riverview Group. Millennium Management is also the general partner of the 100% owner of Integrated Assets II and Integrated Assets and may also be deemed to have shared voting control and investment discretion over securities owned by Integrated Assets II and Integrated Assets.

   Millennium Group Management LLC, a Delaware limited liability company ("Millennium Group Management"), is the managing member of Millennium Management and may also be deemed to have shared voting control and investment discretion over securities owned by Riverview Group. Millennium Group Management is also the general partner of Millennium International Management and may also be deemed to have shared voting control and investment discretion over securities owned by Integrated Assets II and Integrated Assets.

   The managing member of Millennium Group Management is a trust of which Israel A. Englander, a United States citizen ("Mr. Englander"), currently serves as the sole voting trustee. Therefore, Mr. Englander may also be deemed to have shared voting control and investment discretion over securities owned by Riverview Group, Integrated Assets II and Integrated Assets.

   The foregoing should not be construed in and of itself as an admission by Millennium International Management, Millennium Management, Millennium Group Management or Mr. Englander as to beneficial ownership of the securities owned by Riverview Group, Integrated Assets II or Integrated Assets, as the case may be.

(b) Percent of Class:   



   As of the close of business on January 6, 2021, Millennium Management, Millennium Group Management and Mr. Englander may be deemed to have beneficially owned 1,761,594 shares of the Issuer’s Common Stock or 3.4% of the Issuer’s Common Stock outstanding (see Item 4(a) above), which percentage was calculated based on 49,813,547 shares of the Issuer’s Common Stock outstanding as of November 16, 2020, as per the Issuer’s prospectus supplement dated December 10, 2020.
