                             SELLING SECURITYHOLDERS

         The prospectus dated July 3, 2003, relating to the offer for resale of
$889,000,000 aggregate principal amount at maturity of debentures and 20,896,657
shares of our common stock issuable upon conversion of the debentures held by
the selling securityholders, plus an indeterminate number of shares as may
become issuable upon conversion of the debentures by reason of adjustment to the
conversion price and, upon each issuance of shares of Carnival Corporation
common stock to a person, including to a holder of debentures upon conversion of
debentures, an equivalent number of non-detachable trust shares of beneficial
interest in the P&O Princess Special Voting Trust, is amended to replace the
first paragraph and the table under the heading "Selling Securityholders" on
page 74 with the information in the following paragraph and table. We may
further amend or supplement this table from time to time if necessary.

         We originally sold the debentures to the initial purchaser in a private
placement. The debentures were subsequently resold by the initial purchaser to
purchasers, including the selling securityholders listed below, in transactions
exempt from registration. The following table provides, as of July 21, 2003, the
principal amount at maturity of debentures held by such selling securityholder,
the number of shares of common stock beneficially owned by such securityholder
prior to its conversion of any debentures and the number of shares of our common
stock issuable upon conversion of the debentures. This information has been
obtained from the selling securityholders. Selling securityholders representing
an amount of up to an additional $387,300,000 aggregate principal amount at
maturity of debentures will be added to the table in one or more supplements to
this prospectus.
