Footnotes on the original

The footnotes that the prices of these transactions refer to on the original filing.

F7

The price reported is a weighted average sales price. The shares were sold in multiple transactions at prices ranging from $2.70 to $2.71, inclusive. The Reporting Person undertakes to provide to the Issuer, any security holder of the Issuer or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the ranges set forth in this footnote.

Referenced by the price of 1 transaction in Table I.

Footnotes and remarks

Livermore keeps the footnotes that transaction prices refer to, all footnotes of amendments (Form 4/A) and the filing's remarks. Other footnotes, such as how indirect holdings are held or the details of a trading plan, are only in the original on SEC EDGAR.

F1

On January 17, 2024, the Reporting Person filed a Form 4 reporting the vesting of restricted stock units ("RSU"s) between January 13, 2024 and January 15, 2024 and the sale of shares of common stock on January 16, 2024 to satisfy the Reporting Person's tax withholding obligations in connection with the service-based vesting and settlement of the RSUs (the "Original Form 4"). Due to an inadvertent arithmetic error, the number of shares beneficially owned by the Reporting Person following the receipt of the RSUs that vested on January 13, 2024 was incorrectly reported, which error also impacted the beneficial ownership figures reported following the subsequent transactions reported in the Original Form 4. This Form 4/A is being filed to correct the number of shares held by the Reporting Person as of January 16, 2024 after all transactions reported in the Original Form 4.
