            SLOUGH ESTATES PLC COMPLETES ACQUISITION OF DEVELOPMENT
                           COMPANY IN CENTRAL EUROPE

Slough Estates International ('SEI') has completed the €19.1 million acquisition
of GREI (Grontmij Real Estate International), the Central European property
development operations of Grontmij - a leading European engineering firm. The
acquisition gives SEI an immediate presence in Poland, the Czech Republic and
Hungary with development teams already in place and sites ready to develop.

This completes the first phase of the purchase announced in November 2005.
Slough now owns 79 hectares and controls a further 17 ha under short term
options. The logistics sites include 61 ha at Strykow near Lodz, a strategic
location in Central Poland, 10 ha in Poznan, Western Poland, 16 ha adjacent to
Prague airport, and 9 ha on the M1 motorway running west out of Budapest. Also
included is a site for a 16,000 m(2) suburban office development in the Mokotov
district of Warsaw. Moreover Slough has the right of first refusal on two
further sites in Italy and Hungary.

Ian Coull, Chief Executive of Slough Estates, said:

'This acquisition further moves forward the implementation of our strategy of
expansion into Continental Europe, continuing with a clear focus on the core
sectors of logistics, light industrial and suburban office.'

SEI's Managing Director in Europe, Walter Hens, added:

'We are delighted to have purchased a business which is so closely aligned to
SEI in terms of sector and so complementary in terms of location. The team we
have acquired is very experienced and with the addition of Slough's financial
strength, they will make a significant impact in the Central European markets.'

Simon Hollins - currently Slough Estates' Head of European Development - will
take charge of the new Central European Division, relocating in the first
instance to Maastricht, the existing headquarters of the GREI team.
