MBE system sales are up 10% to €11.1 million. This growth reflects the good level of sales to research
centers and the upturn in demand from industrial firms for compound semiconductors. 10 MBE machines
were delivered in 2010, including two production systems.

In line with the objectives set, the services and accessories business has continued to develop at a strong rate, with revenues climbing to a record level of €6.5 million, representing growth of 38% in relation to 2009.

Sales of evaporation sources and cells increased by 24%, confirming the relevance of the strategy to
diversify into the strong-growing markets for organic LEDs (OLED) and thin-layer solar panels (CIGS
technology).

In 2010, the breakdown of RIBER's sales was as follows: Europe (56% of which 35% in Russia), Asia
(28%) and North America (16%).

Favorable outlook for 2011

RIBER has good visibility for 2011. The order book represents €17.3 million, 6.9 times higher than at
December 31st, 2009. It includes 10 MBE systems, with three production systems and seven research
systems. One of these systems is deliverable after 2011.

It is important to note that the order book does not include the major OLED effusion cell contract signed at the start of January 2011 for several million euros.

RIBER’s commercial development illustrates the relevance of its strategy, based on:

• Continuing to further strengthen RIBER's leadership on the market for MBE research and production
systems;
• Capitalizing on the installed base and growing sales of epitaxy equipment (effusion cells, etc.), spare
parts and accessories, as well as the corresponding services;
• Releasing a range of high value-added equipment and services on the market for strong-growth
application fields (thin-layer solar panels, OLED lighting and flat screens, etc.).

2010 full-year earnings will be released on March 24th, 2011 (after close of trading).
