        <footnote id="F1">Equivalent shares as reported by the Tredegar Corporation Retirement Savings Plan (the &quot;Savings Plan&quot;) trustee.  The Savings Plan maintains its records through unit accounting and not share accounting.  Therefore, the number of equivalent shares can fluctuate up or down depending upon the unit value within the trust solely as a result of a change in the fair market value of Tredegar stock even if the employee takes no action in the Savings Plan.  The amount reported includes units acquired in exempt transactions under Rule 16b-3 pursuant to the Savings Plan during the period from April 20, 2004 through March 7, 2006.</footnote>
        <footnote id="F2">Total number includes stock options with varying exercisable dates, expiration dates and conversion prices.</footnote>
