        <footnote id="F1">Reflects the one-for-two reverse stock split effected in connection with, and immediately following, the Spin-Off by IAC of HSN, Inc. (&quot;HSN&quot;), Interval Leisure Group, Inc. (&quot;ILG&quot;), Ticketmaster and Tree.com, Inc. (&quot;TREE&quot;) and the one-for-two reverse stock split (the &quot;Reverse Stock Split&quot;) on August 20, 2008.</footnote>
        <footnote id="F2">In connection with the Spin-Off, stock options granted prior to December 31, 2007 were converted into options to purchase common stock of each of IAC, HSN, ILG, Ticketmaster and Tree.com, with adjustments (to maintain pre- and post-spin-off values) to the number of shares of common stock underlying each option and the per share exercise prices to reflect the Spin-Off and Reverse Stock Split. These previously granted stock options have the same vesting and other applicable terms and conditions as they did immediately prior to the Spin-off and Reverse Stock Split.  Reflects IAC stock options, as adjusted on the basis described immediately above.</footnote>
