        <footnote id="F1">In their previously filed Statements of Changes in Beneficial Ownership on Form 4 and Annual Statement of Changes in Beneficial Ownership on Form 5, the Reporting Person included shares of Common Stock underlying their options in the calculation of their holdings of Common Stock and reported them in Table I, in addition to separately reporting these options in Table II. Column 5 of Table I now correctly reflects the aggregate amount of direct beneficial ownership of securities owned (not including any derivative securities) as of the last reported transaction.</footnote>
