Land Securities and Slough Estates Agree

Slough Estates PLC
                  

SLOUGH ESTATES plc
LAND SECURITIES GROUP PLC

Land Securities Group PLC ('Land Securities') and Slough Estates plc ('Slough
Estates') announce today that they have exchanged contracts for the property
swap announced on 24 August 2004. The transaction will involve an exchange of
the majority of their respective retail and industrial property portfolios with
a combined value of approximately £700 million.

Following completion of the transaction Land Securities will own The Howard
Centre in Welwyn Garden City, the Lewisham Centre in South London, the Bishop
Centre in Taplow and a 50% interest in Buchanan Galleries in Glasgow. The
portfolio totals some 91,300 sq. m. of retail space and has a rent roll of £20.4
million.

In return Slough Estates will increase its industrial portfolio by some 300,000
sq. m of space. Slough will be acquiring a total of 23 properties, with a rent
roll of approximately £22 million including a rental guarantee. The difference
in the relative values of the portfolios will be met by a cash consideration of
£18.5 million, payable to Slough Estates.

Land Securities will retain industrial properties with a value of £56 million
(31 March 2004), the majority of which have medium term potential for
development for alternative uses and Slough Estates will retain its share in
shopping centres in York and Surrey Quays, which will be sold in due course.

Francis Salway, Land Securities Chief Executive said 'A property swap is an
effective way to acquire additional retail assets off market - given our
decision earlier this year to focus our activities on sectors where we had
market leading positions. While the industrial portfolio has performed well it
proved too small to impact substantially on the Group's overall performance. We
are very pleased with the scope the new assets offer in terms of asset
management and development opportunities.'

Ian Coull, Chief Executive of Slough Estates, added: 'This swap is a good deal
for Slough as it sharpens our sector focus at a time in the cycle when it is
right for us to increase our exposure to industrial property and to prepare
ourselves for a possible REIT structure in the next couple of years. We had an
excellent portfolio of retail assets but it was too small a portfolio to give us
meaningful sector diversification whereas this swap was a one-off opportunity to
acquire a substantial and first class portfolio of industrial assets in the
South of the UK.'
