        <footnote id="F1">On February 28, 2006, Mr. Mylod was granted 20,000 priceline.com &quot;performance shares.&quot;  The exact number of shares to be issued to Mr. Mylod, which could be as many as three times the initial grant or, alternatively, no shares, will be determined based on priceline.com's performance against a group of three &quot;peer&quot; companies.  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 agreement) of priceline.com and/or termination of employment in certain circumstances.</footnote>
        <footnote id="F2">On February 28, 2006, Mr. Mylod was granted 5,000 shares of restricted common stock, par value $0.008 per share of priceline.com.  The shares granted on February 28, 2006 are scheduled to vest on February 28, 2007, subject to certain contingencies and provisions allowing for accelerated vesting in certain instances.</footnote>
