        <footnote id="F1">Represents 18,856 shares of Series B Common Stock, par value $0.001 per share (&quot;Series B Common Stock&quot;), automatically converted into Series A Common Stock, par value $0.001 per share (&quot;Series A Common Stock&quot;), and 25,275 shares of Series A Common Stock subsequently withheld by the Issuer to satisfy tax withholding obligations in connection with the vesting and settlement of restricted stock units (&quot;RSUs&quot;).</footnote>
        <footnote id="F2">Each share of Series B Common Stock is convertible at any time at the option of the holder into one share of Series A Common Stock of the Issuer, and will automatically convert into Series A Common Stock upon the occurrence of certain events as set forth in the Issuer's certificate of incorporation. The Series B Common Stock has no expiration date.</footnote>
        <footnote id="F3">Consists of (i) 19,285  shares of Series A Common Stock and (ii) 168,000 unvested RSUs awarded under the 2023 Stock Incentive Plan, each representing the contingent right to receive one share of Series A Common Stock upon vesting and settlement.</footnote>
        <footnote id="F4">Consists of (i) 178,788 shares of Series B Common Stock and (ii) 526,042 unvested RSUs awarded under the 2015 Stock Incentive Plan, each representing the contingent right to receive one share of Series B Common Stock upon vesting and settlement.</footnote>
    </footnotes>

    <remarks>This amendment amends and restates the Form 4 originally filed on February 16, 2024 to correct the number of shares converted by, and withheld from, the Reporting Person in connection with tax withholding obligations associated with the vesting of RSUs.</remarks>
