Item 4.

Ownership:

This Statement on Schedule 13G relates to shares of Common Stock that the Reporting Persons have the right to acquire upon conversion of shares of Series B-2 Preferred Stock (“Series B-2 Preferred Stock”) held directly by VGOP and VGOD. VGOP owns 85,612 shares of Series B-2 Preferred Stock and VGOD owns 42,167 shares of Series B-2 Preferred Stock, and the Series B-2 Preferred Stock has an initial conversion rate of 294.1176 shares of Common Stock per share of Series B-2 Preferred Stock. However, the Certificate of Designation for the Series B-2 Preferred Stock provides that none of VGOP, VGOD, nor their affiliates shall be entitled to convert shares of Series B-2 Preferred Stock unless such conversion would not result in VGOP and VGOD, together with their affiliates, beneficially owning more than 9.5% of the total number of shares of Common Stock outstanding (the “Blocker”). Accordingly, the amount of shares of Common Stock reported as beneficially owned by the Reporting Persons set forth herein excludes shares of Common Stock that the Reporting Persons do not currently have the right to acquire upon conversion of the Series B-2 Preferred Stock held directly by VGOP and VGOD due to the Blocker (and applies the Blocker pro rata across VGOP and VGOD). Without giving effect to the 9.5% blocker provision, the Series B-2 Preferred Stock held by VGOP would be convertible into 25,179,995 shares of Common Stock and the Series B-2 Preferred Stock held by VGOD would be convertible into 12,402,056 shares of Common Stock, for an aggregate of 37,582,051 shares of Common Stock.

The percentages set forth herein are calculated based on (i) 77,198,577 shares of Common Stock outstanding as of February 28, 2022, as reported in the Company’s Form 10-K filed with the Commission on March 8, 2022, and (ii) 8,103,527 shares of Common Stock that the Reporting Persons currently have the right to acquire upon conversion of the Series B Preferred Stock, subject to the Blocker.
