        <footnote id="F1">Jack W. Schuler is the sole trustee of the Jack W. Schuler Living Trust.</footnote>
        <footnote id="F2">The Reporting Person disclaims beneficial ownership of the shares of the Issuer owned by the Schuler Family Foundation (the &quot;Foundation&quot;). Although the Reporting Person is the President of the Foundation and makes investment decisions regarding the Foundation's securities transactions, by virtue of the Foundation's status as a 501(c)(3) tax-exempt organization, the Reporting Person may not, and in fact, does not personally derive any profit from the Foundation's transactions in the Issuer's common stock. As a result, this Form 4 is a voluntary report with respect to these purchases of the Issuer's common stock by the Foundation.</footnote>
        <footnote id="F3">The price reported in Column 4 is a weighted average price. These shares were purchased in multiple transactions at prices ranging from $6.12 to $6.49, inclusive. The reporting persons undertake 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 purchased at each separate price within the range.</footnote>
    </footnotes>

    <remarks>This Form 4 does not include securities acquired or held by the Tino Hans Schuler Trust, Tanya Eva Schuler Trust, Therese Heidi Schuler Trust, Schuler Grandchildren LLC, Schuler Descendants Trust or JS Grandchildren Trust, because the Reporting Person has no pecuniary interest, as such term is used for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, in such securities.</remarks>
