SLOUGH ESTATES LETTING TO BLACKBERRY

Slough Estates plc has let a flagship grade A office development on the Slough
Trading Estate, to Research in Motion (RIM), the company behind the
BlackBerry(R) mobile communication device.

In a transaction that represents one of the largest Thames Valley lettings this
year and previously one of the largest remaining unlet sites in the Slough
Estates portfolio, RIM has agreed terms to occupy the 69,000 sq ft building as
its new European headquarters, on the basis of a 15 year lease. The rent is
approximately £25 per sq ft with an initial rent free period.

RIM has also taken options on further business space to accommodate future
expansion including 60,000 sq ft of offices and a 50,000 sq ft data centre.

John Heawood, Group Executive Director of UK Property at Slough Estates said:

'Research in Motion is a leader in the field of mobile communications, and joins
a growing number of high technology, research and development oriented companies
choosing Slough Trading Estate as a location. Apart from providing top quality
business space, we are able to accommodate the growth such businesses expect to
see. Our substantial investment in our award-winning Business Watch programme
also makes for a very secure environment in which to operate.'

Slough Trading Estate benefits from its prime location at the centre of the
Thames Valley, with both Heathrow and the M4 in close proximity. With these
advantages, the area has already drawn a number of other high profile leading
edge technology occupiers, including O2, Vodafone, LG Electronics and Elcom. The
additional presence of Research in Motion will further bolster the development
of Slough Trading Estate's growing technology cluster.

redevelopment of high specification offices on the Bath Road; the letting
absorbs the last block of this new space. Slough Trading Estate has recently
been demolishing nearby buildings to meet the ongoing demand for new space for
businesses of all sizes.
