              RESPONSE TO P&O PRINCESS CRUISES PLC ("P&O PRINCESS")

Carnival notes the announcement made this morning by P&O Princess that it will
delay its EGM only until 14 February 2002.

Carnival has today again requested a meeting with P&O Princess in order to
reduce the pre-conditionality of its Offer. Carnival has consistently sought to
provide as much certainty as possible for P&O Princess Shareholders. Accordingly
Carnival again requests that P&O Princess provides the information for Carnival
to be able to reduce the pre-conditionality of its Offer.

Describing Carnival's Offer as a spoiling tactic is tantamount to accusing
Carnival and its advisers of creating a false market in P&O Princess Shares, in
breach of the Takeover Code and the FSA Code of Market Conduct. Carnival utterly
repudiates any such suggestion.

Carnival wishes to correct the misleading announcement made by P&O Princess this
morning:

         -        Carnival's Offer is not seeking to force P&O Princess
                  Shareholders to vote down the merger proposal. Instead,
                  Carnival is proposing that the board of P&O Princess should,
                  in the interests of its shareholders, delay the EGM until the
                  regulators have concluded their review of both proposals.
                  Carnival wishes to ensure that a level playing field is
                  established in order that P&O Princess Shareholders can then
                  consider both proposals on the basis of value.

         -        Both proposals are conditional on regulatory approval and
                  neither combination can proceed without, inter alia, US
                  antitrust clearance.

Micky Arison, the Chairman and Chief Executive of Carnival, said:

"We are not spoilers. We have talked to P&O Princess about a combination of our
to businesses over a long period of time. The only spoiling tactics are the
poison pills entered into by the P&O Princess board, which have destroyed
shareholder value and which have been entered into in the full knowledge of our
longstanding interest in P&O Princess."

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements in this announcement constitute "forward-looking statements"
within the meaning of the Private Securities Litigation Reform Act of 1995.
Carnival has tried, wherever possible, to identify such statements by using
words such as "anticipate," "assume," "believe," "expect," "intend," "plan" and
words and terms of similar substance in connection with any discussion of future
operating or financial performance. These forward-looking statements, including
those which may impact the forecasting of Carnival's net revenue yields, booking
levels, price, occupancy or business prospects, involve known and unknown risks,
uncertainties and other factors, which may cause Carnival's actual results,
performances or achievements to be materially different from any future results,
performances or achievements expressed or implied by such forward-looking
statements. Such factors include, among others, the following: general economic
and business conditions which may impact levels of disposable income of
consumers and the net revenue yields for Carnival's cruise products; consumer
demand for cruises and other vacation options; other vacation industry
competition; effects on consumer demand of armed conflicts, political
instability, terrorism, the availability of air service and adverse media
publicity; increases in cruise industry and vacation industry capacity;
continued availability of attractive port destinations; changes in tax laws and
regulations; Carnival's ability to implement its shipbuilding program and to
continue to expand its business outside the North American market; Carnival's
ability to attract and retain shipboard crew; changes in foreign currency rates,
security expenses, food, fuel, insurance and commodity prices and interest
rates; delivery of new ships on schedule and at the contracted prices; weather
patterns; unscheduled ship repairs and dry-docking; incidents involving cruise
ships; impact of pending or threatened litigation; and changes in laws and
regulations applicable to Carnival.

Carnival cautions the reader that these risks may not be exhaustive. Carnival
operates in a continually changing business environment, and new risks emerge
from time to time. Carnival cannot predict such risks nor can it assess the
impact, if any, of such risks on its business or the extent to which any risk,
or combination of risks may cause actual results to differ from those projected
in any forward-looking statements. Accordingly, forward-looking statements
should not be relied upon as a prediction of actual results. Carnival undertakes
no obligation to publicly update or revise any forward-looking statements,
whether as a result of new information, future events or otherwise.
