                            SHAREHOLDER EGM CIRCULAR


Carnival notes the release of P&O Princess' circular to its shareholders
convening P&O Princess' Extraordinary General Meeting for 14 February 2002.

Carnival's preliminary review of the P&O Princess shareholder circular and the
associated documents on display (together the "Documents") confirms its belief
that the board of P&O Princess entered into the "poison pill" arrangements when
it was aware of Carnival's strong interest in P&O Princess, contrary to P&O
Princess Shareholders' best interests and to the detriment of shareholder value.

Carnival continues to believe that its Offer is clearly superior to the Royal
Caribbean Proposal.

Carnival and its advisors are reviewing the Documents and will make a full
response in due course.

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.
