        <footnote id="F1">On March 5, 2008, Mr. Finnegan was granted 3,168 priceline.com Incorporated (the &quot;Company&quot;) performance share units.  The exact number to be issued to Mr. Finnegan, which could be as many as one to two times the initial grant, will depend upon, among other things, the Company's financial performance.  The shares, if any, will be issued on or about March 1, 2011 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>
