Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Represents trust shares (the "Trust Shares") of beneficial interests in P&O Princess Voting Trust (the "Trust"). In connection with the dual listed company transaction between Carnival plc (f/k/a P&O Princess Cruises plc) and Carnival Corporation (the "DLC Transaction"), 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 "Carnival Corporation Common Stock"). 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.
(2) Represents shares released from restriction from a Restricted Stock Unit award granted in 2007.
(3) Represents settlement of dividend equivalents accummulated during the restricted period of a restricted stock unit award originally granted in 2007, which has now vested.
(4) Represents a surrender of shares to satisfy tax obligation on the vesting of the Restricted Stock Unit.
(5) No expiration date. The award will either vest or be forfeited pursuant to the terms of the Restricted Stock Unit Agreement between the reporting person and the issuer.
