    <footnotes>
        <footnote id="F1">On a Form 4 filed on February 18,2009, the reporting person reported a weighted average price in Column 4 for shares sold in multiple transactions at prices ranging from $21.65 to $21.69, inclusive.  The reporting person omitted the price range from footnote 1 of the Form 4 because the information was unavailable from the 401(k) plan administrator at the time of the filing.  The reporting person undertakes to provide to Encore Wire Corporation, any security holder of Encore Wire Corporation, 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 range set forth in this footnote.</footnote>
