F3	On November 28, 2022, the Issuer and Wood River entered into Amendment No. 1 to Convertible Senior PIK Toggle Note Due 2027 ("Amendment No. 1") to the Convertible Senior PIK Toggle Note Due 2027, dated February 18, 2022 (as amended by Amendment No. 1, the "Convertible Notes"), whereby the initial conversion price was reduced by $5.00 from $34.936625 per Public Share to $29.936625 per Public Share by increasing the initial conversion rate from 28.623257 Public Shares per $1,000 principal amount of the Convertible Notes to 33.400100 Public Shares per $1,000 principal amount of the Convertible Notes. Wood River was not issued additional principal amount of the Convertible Notes in connection with Amendment No. 1, and the transaction in Table II is reported solely to reflect the change in conversion price on the Convertible Notes as a result of such amendment.
