In 2006 VOLGABUS and Rio Tinto Alcan have signed a cooperation
agreement for the development of a new bus family based on the EcoRange(R)
system. Since then VOLGABUS has built more than 400 buses with EcoRange(R)
body structures for the Russian market. VOLGABUS, founded in 1995, made
innovation a cornerstone of its business philosophy and has quickly become a
well-known force in the Russian bus market.

"We are very pleased that Moscow and St Petersburg have
selected buses from VOLGABUS with our innovative aluminium EcoRange(R) body
structure system," said Paul Warton, president Alcan Extrusions and
Automotive Structures. "Due to its high-end technical characteristics, it
offers multiple benefits to bus builders and operators," he added.

The lightweight EcoRange(R) body will help to reduce fuel
consumption and CO2 emissions. For enhanced passengers safety the EcoRange(R)
body structure includes two aluminium rollover rings.

The EcoRange(R) body structure system, developed by Alcan
Extrusions and Automotive Structures, includes high-performance aluminium
extrusions and aluminium bolted connections for fast and easy assembly.

The 14.7m long, 3-axle buses will have three doors and are
designed for a capacity of 173 passengers. The buses will be powered by a
Deutz 210 kW engine with ZF gear box and ZF axles. VOLGABUS will start
production of the buses in May in its bus plant in the Volgograd region and
delivery to Moscow and St Petersburg will take place until September 2010.
