        <footnote id="F1">Reflects the acquisition of common stock, par value $0.01, of Ticketmaster (&quot;TM&quot;) in connection with the spin-off by IAC/InterActiveCorp (&quot;IAC&quot;) of TM, which was completed following the close of the market on August 20, 2008.   The distribution of TM common stock was effected by way of a dividend, pursuant to which holders of IAC common stock on August 11, 2008 received one-fifth of one share of TM common stock for every one share of IAC common stock held.</footnote>
        <footnote id="F2">Includes (i) 4,441 shares of Ticketmaster common stock held by Mr. Barnes directly, (ii) 6,005 shares of Ticketmaster common stock held in trust with Mr. Barnes's spouse, (iii) 42 shares of Ticketmaster common stock held in an IRA account maintained by Mr. Barnes's spouse amd (iv) 500 shares of Ticketmaster common stock held by Mr. Barnes son, who shares his household.  Mr. Barnes disclaims beneficial ownership of the shares of Ticketmaster common stock described in (ii), (iii) and (iv) above.</footnote>
        <footnote id="F3">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 the receipt of TM stock options in connection with the adjustment described immediately above.</footnote>
