                  ROYAL CARIBBEAN/P&O PRINCESS DEAL REFERRED TO
                            UK COMPETITION COMMISSION

Carnival notes today's announcement by the UK Secretary of State for Trade and
Industry that the proposed Royal Caribbean/P&O Princess deal has been referred
to the UK Competition Commission. The Competition Commission is due to make its
report by 20 May 2002 although the ultimate decision of the Secretary of State
will not be available until some time after that.

Both the Carnival and Royal Caribbean proposals are conditional on the result of
antitrust reviews in Europe and the US and these reviews will still be
outstanding on 14 February 2002, the date of P&O Princess' EGM. The Secretary of
State's decision does not affect the advice that Carnival has received about the
prospects for clearance of its Offer by the European Commission. Carnival
continues to believe strongly that the interests of P&O Princess Shareholders
are best served by delaying the EGM so that any decision on the merits of the
competing proposals can be made after the results of the antitrust reviews are
known.

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

"P&O Princess has claimed that the Royal Caribbean proposal is more deliverable
than Carnival's offer on antitrust grounds. P&O Princess' analysis has proven to
be wrong and today's decision by the Secretary of State makes P&O Princess'
determination not to speak to us totally indefensible.

Carnival has said all along that both transactions are similarly situated from a
regulatory standpoint. The logic for postponing the EGM has been reinforced by
the Secretary of State's decision today. The P&O Princess board's advice to its
shareholders on regulatory issues raises significant questions about its
credibility."

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements in this announcement constitute "forward-looking statements"
within the meaning of the US 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.
