(3) | On December 23, 2021, the Registrant filed a Registration Statement (File No. 333-261887) in which it paid a registration fee of $124,098.18. This registration fee reflected an initial registration of (a) 12,326,472 shares of Common Stock issuable upon the exercise of warrants of the Registrant, (b) the resale from time to time of (i) up to 124,931,453 shares of Common Stock, and (ii) 366,533 warrants by the selling security holders named in that prospectus (c) the resale from time to time of $200,000,000 in aggregate principal amount of 6.00% convertible senior notes due 2026 (the “2026 Convertible Notes”) of the Registrant, and up to 23,058,494 shares of common stock issuable upon conversion of the 2026 Convertible Notes. However, in the Registrant’s Amendment No. 3 to the Registration Statement filed on February 8, 2022, the number of shares of Common Stock being offered was reduced by 113,250,000 shares of Common Stock. The Registration Statement (File No. 333-261887) went effective without the 113,250,000 shares of Common Stock. Due to the reduction in shares of Common Stock registered the Company overpaid the registration fee by $83,776.23. The shares of Common Stock that were removed from Amendment No. 3 to the Registration Statement are now being registered with this Registration Statement. The amount previously overpaid is being applied to this registration fee of $52,911.31. |
