Following their announcements made on 8 January 2003, P&O Princess Cruises plc
("P&O Princess") and Carnival Corporation ("Carnival") announce that final
shareholder documents relating to the dual listed company ("DLC") transaction
have been filed with the US Securities and Exchange Commission (the "SEC").
These documents include the final draft circular to P&O Princess shareholders

the United Kingdom Listing Authority ("UKLA") and, accordingly, has not yet been

will be available for inspection at the Document Viewing Facility of the
Financial Services Authority at 25 The North Colonnade, London E14 5HS. Subject
to UKLA documentation approval being received, documents are expected to be
mailed to shareholders today, Monday 17 March 2003.

These documents contain details of the shareholder meetings to be convened to
approve the DLC transaction. It is intended that the Carnival Special Meeting
will be held on 14 April 2003 and that the P&O Princess Extraordinary General
Meeting ("EGM") will be held on 16 April 2003.

This announcement contains details of the expected timetable to completion, the
shareholder meetings and the documentation to be sent to shareholders. The Final
Draft Circular and this announcement also contain an update on current trading
and prospects and details of the deferred consideration payable in respect of
the purchase of Aida Cruises.

A further announcement will be made once final documentation approvals have been
received.

TRADING UPDATE

CARNIVAL

Since the start of the calendar year, booking volumes have been less than
expected. Year to date booking volumes for 2003 are approximately equal to last
year's levels, but have not increased commensurate with the increase in
Carnival's 2003 capacity. Carnival believes bookings in 2003 continue to be
impacted by the uncertain economic environment and concerns regarding a war with
Iraq compounded by security alerts issued by various national governments. These
factors have caused Carnival to reduce cruise pricing to stimulate incremental
demand for the first and second quarters.

For its recently completed first quarter, Carnival expects net revenue yields to
be approximately equal to last year's levels. The current environment for travel
continues to have the most significant effect on Carnival's second quarter 2003
bookings. The uncertainty regarding a possible war with Iraq is causing further
deterioration in pricing for the second quarter, as indicated in Carnival's last
guidance. As the booking pattern has moved much closer to sailing and because of
the uncertainty regarding the geopolitical situation, Carnival is not able to
give specific guidance for second quarter net revenue yields, other than, it
expects them to be less than last year. The commencement of a war with Iraq
would likely have further negative impact on second quarter net revenue yields.

With respect to costs, Carnival continues to expect cost per available berth day
in the first quarter, excluding air costs and commissions, to be up
approximately 6-8 per cent. compared to last year's levels. For the second
quarter, Carnival continues to expect cost per available berth day to be up
approximately 10-12 per cent. compared



to last year's levels. As previously disclosed, Carnival's higher cost per
available berth day in the first half of the year is due primarily to increased
fuel costs, compounded by the frontloading of advertising costs, as well as
higher insurance, environmental, and security costs.

Carnival is still expected to record non-operating income of approximately $0.03
per share for insurance recoveries in the first quarter of 2003.

For the second half of 2003, booking volumes remain ahead of last year's levels
but not commensurate with the increase in capacity expected for the second half
of the year. Prices on these bookings remain slightly below that of the prior
year. As a result of the close-in booking pattern and the uncertain geopolitical
environment, it is too early to give net revenue yield guidance for the
remainder of 2003. Commencement of a war with Iraq, subject to the duration of
such a war, would likely have negative impact on net revenue yields for the
second half of 2003. Excluding the possible impact of higher fuel costs,
operating cost per available berth day in the second half of 2003 is expected to
be down slightly as compared to the prior year.

P&O PRINCESS

As reported with the results for the fourth quarter on 6 February 2003, the
booking environment since the start of the year has not been as strong as normal
for the time of year. P&O Princess believes that this is a reflection of the
current geopolitical and economic uncertainties.

As previously announced and in response to demand trends from North American
passengers, Grand Princess, one of the two Princess ships originally scheduled
to sail in the Mediterranean this summer, has been redeployed. She will now stay
in the Caribbean for the whole year. In addition, as previously announced,
Princess' capacity in Alaska this summer has been reduced by the cancellation of
number of cruises due to the delivery date for the new ship, Island Princess,
being delayed.

Despite relatively low booking volumes in recent weeks, the proportion of
capacity for 2003 as a whole for Princess remains in line with the position a
year ago, with average achieved yields ahead. Cumulative bookings in the UK and
Germany are ahead of the position a year ago, but not by as much as the increase
in capacity that P&O Princess has in these markets in 2003. On a combined basis,
yields in these two markets are below the cumulative position this time last
year, mainly as a result of a change in mix of business, including the
introduction of the lower priced Ocean Village brand, but yields are benefiting
from favourable exchange rates when converted to P&O Princess' reporting
currency of US dollars.

Higher fuel prices and exchange movements are increasing unit costs, offset by
underlying unit cost savings.

THE COMBINED GROUP

The directors of each of Carnival and P&O Princess believe that the long term
prospects for the Combined Group will be enhanced considerably by entering into
the



DLC transaction. The Combined Group will have the brands and the fleet to enable
it to maximise the potential offered by growth in the worldwide cruise vacation
industry. Furthermore, the Combined Group will benefit from the synergies
arising from the combination. In addition, the Combined Group will have
substantial financial flexibility, with strong operating cash flow, low leverage
and a strong balance sheet. This financial profile means that, as well as having
the upside potential from the combination, shareholders in the Combined Group
also benefit from downside protection.

DEFERRED CONSIDERATION PAYABLE IN RESPECT OF AIDA CRUISES

In September 2000, P&O Princess acquired the 49 per cent. it did not own in Aida
Cruises from Deutsche Seereederei GmbH ("DS") (a company wholly-owned by a
non-executive director of P&O Princess, Horst Rahe, and his family). As
announced at the time of the acquisition, an element of deferred consideration
in respect of this transaction was also payable in respect of any 12 month
period up to the end of 2005 with such payment being based on the results of
Seetours. Seetours comprises the German operations of P&O Princess and includes
the business of AIDA Cruises and A'ROSA. In the event of a change of control of
P&O Princess, or if certain members of the P&O Princess Group fail to comply
with other specific restrictions (including material breach of
non-compete/non-solicitation provisions), DS is entitled to accelerate the
payment of the total outstanding balance of the deferred consideration.

Completion of the DLC transaction will trigger the right to such payment. Since
P&O Princess entered into the Implementation Agreement with Carnival, DS has
confirmed to P&O Princess that it will exercise this right. Accordingly, P&O
Princess will pay Euro 58.8 million to DS shortly after completion, and the Aida
Cruises sale and purchase agreement will then terminate.

It is being announced in Germany today that Horst Rahe has agreed to accept the
honorary position of Life President of Seetours on completion of the DLC
transaction.
