Item 4(a)
Amount Beneficially Owned:
As of the date hereof, the Reporting Person may be deemed the beneficial owner of 7,500,000 shares of Common Stock that the Reporting Person has the right to acquire upon conversion of shares of Series X Convertible Preferred Stock, par value $0.0001 per share, of the Corporation (the “Series X Preferred Stock”).
On April 6, 2022, the Reporting Person entered into a Securities Purchase Agreement with the Issuer pursuant to which the Reporting Person (i) purchased 7,500 shares of Series X Preferred Stock at a price of $1,000 per share, and (ii) agreed to purchase an additional 7,500 shares of Series X Preferred Stock at a price of $1,000 per share if the Issuer raises additional capital by an outside date (the “Second Tranche”). The Series X Preferred Stock has an initial conversion rate of 1,000 shares of Common Stock per share of Series X Preferred Stock, subject to adjustment as set forth in the Certificate of Designation. However, the Certificate of Designation for the Series X Preferred Stock provides that the Reporting Person shall not have the right to convert any portion of the Series X Preferred Stock to the extent that, after giving effect to an attempted conversion, the Reporting Person, together with its affiliates and any persons acting as a “group” with the Reporting Person, exceeds 9.9% (the “Blocker”). Accordingly, to the extent the Second Tranche is issued, the amount of shares of Common Stock that the Reporting Person has the right to acquire upon conversion of the Series X Preferred Stock will be limited by the Blocker.
Item 4(b)
Percent of Class:

As of the date hereof, the Reporting Person may be deemed the beneficial owner of approximately 7.4% of the shares of Common Stock outstanding. The percentage set forth herein is calculated based on (i) 93,986,470 shares of Common Stock outstanding as of March 25, 2022, as reported in the Issuer’s definitive proxy statement on Schedule 14A, filed on April 8, 2022, and (ii) the 7,500,000 shares of Common Stock that the Reporting Person currently has the right to acquire upon conversion of the Series X Preferred Stock.
