            HELIOSLOUGH LETS AND SELLS THE FINAL PHASE OF TRAXPARK.

HelioSlough has let the final unit at its Traxpark development in Doncaster,
South Yorkshire and has sold its Traxpark investment to a client of Morley Fund
Management for £10.2 million, reflecting a net initial yield of 6%

The 120,979 sq ft (11,239 sq m) warehouse/distribution facility, with
self-contained service yard, has been let to national electrical retailers,
Miller Brothers on a 15-year lease at a rent of £574,650 pa for the base
building. The letting includes a further fit-out package of additional office
space. Miller Brothers are already based in Doncaster and this letting is a
relocation of their DC and head office facility.

Mike Hughes of HelioSlough comments: 'We built the final phase speculatively due
to demand for good quality warehouse space in a great location. Traxpark is well
positioned, with good access to the east coast ports, the A1 and M1, and is rail
connected via an intermodal facility. The sale price achieved reflects the
strength of the development.'

The 40 acre (16 hectare) Traxpark development comprises 625,979 sq ft (58,153 sq
m), earlier phase comprising Power Europe and Wincanton (formerly P&O Trans
European).

King Sturge and M3 advised HelioSlough on the letting and investment sale. Gent
Visick represented Miller Brothers Electrical and Morley Fund Management was
advised by Sanderson Weatherall.

HelioSlough is a joint venture between Helios Properties plc and Slough Estates
International.
