        <footnote id="F1">The deferred stock units (&quot;DSU's&quot;) were granted under the RadioShack 2004 Deferred Stock Unit Plan for Non-Employee Directors upon the director's attendance at his or her initial meeting of the Board of Directors. One-third of the units granted vest on each of the first three anniversary dates of the date of grant. All unvested units immediately vest upon occurrence of certain events such as a change in control or a separation from the Board of Directors. Units convert to common stock on a one-for-one basis upon a change in control or thirty (30) days following separation from the Board of Directors.</footnote>
        <footnote id="F2">The DSU's have no conversion or exercise price.</footnote>
        <footnote id="F3">See footnote (1).</footnote>
        <footnote id="F4">The DSU's have no expiration date.</footnote>
