        <footnote id="F1">On March 5, 2007, Mr. Millones was granted 2,500 priceline.com Incorporated (the &quot;Company&quot;) performance share units.  The exact number of shares to be issued to Mr. Millones, which could be as many as two times the initial grant or, alternatively, no shares, will depend upon, among other things, the Company's financial performance.  The shares, if any, will be issued on or about the third anniversary of the date of grant or earlier, in the event of, among other things, a &quot;change in control&quot; (as defined in the performance share unit agreement) of the Company and/or termination of employment in certain circumstances.</footnote>
        <footnote id="F2">On March 5, 2007, Mr. Millones was granted 7,500 shares of priceline.com Incorporated restricted common stock, par value $0.008 per share.  100% of the grant will vest on March 5, 2010, subject to certain contingencies and provisions allowing for accelerated vesting in certain instances, including, without limitation, upon a &quot;change in control&quot; and/or termination of employment.</footnote>
