Each share of the Series X¹ Preferred is convertible into 55.55 Shares.

As of the close of business on December 30, 2020, the Series X¹ Preferred Warrant Blocker limits the exercise of Series X¹ Preferred Warrants by the Reporting Persons to 0 out of the 2,789,299 Shares underlying the Series X¹ Preferred Warrants owned by the Reporting Persons in the aggregate.
