        <footnote id="F1">Represents trust shares (the &quot;Trust Shares&quot;) of beneficial interests in P&amp;O Princess Voting Trust (the &quot;Trust&quot;).  In connection with the dual listed company transaction between Carnival plc (fka P&amp;O Princess Cruises plc) and Carnival Corporation (the &quot;DLC Transaction&quot;), Carnival plc issued one special voting share to the Trust and, following a series of transactions, the Trust Shares were distributed to holders of common stock of Carnival Corporation (the &quot;Carnival Corporation Common Stock&quot;).  Since completion of the DLC Transaction on April 17, 2003, if Carnival Corporation issues Carnival Corporation Common Stock to a person, the Trust will issue an equivalent number of Trust Shares to such person.  The Trust Shares are paired with shares of Carnival Corporation Common Stock and are represented by the same stock certificate.  The Trust Shares represent a beneficial interest in the Carnival plc special voting share.</footnote>
        <footnote id="F2">On January 28, 2011, the reporting person was granted 3,586 performance-based restricted stock units (&quot;Performance RSUs&quot;).  The Reporting Person may earn from 0-200% of his target amount of Performance RSUs depending on the extent of Carnival Corporation &amp; plc's earnings per share growth over the three-year performance period ending with fiscal 2013, subject to his continued employment during the performance period (with earlier partial vesting in certain cases upon eligibility for retirement, or death or disability, prior to the expiration of the performance period).  Because, as of the date of the grant, the Reporting Person was eligible for retirement due to his age, 1,435 Performance RSU's vested on January 28, 2011.</footnote>
        <footnote id="F3">Represents a surrender of shares to satisfy tax obligation on the vesting of the Performance RSUs.</footnote>
