Sales

Consolidated sales for the 1st quarter grew by 13% to EUR 63.3
million (up 15% in 2009).
Foreign exchange effects were positive by
EUR 0.3 million.

This growth confirms the supremacy of SLIT over SCIT,
respectively posting growth of 17% and a decline of 8% over the 1st
quarter. SLIT now accounts for 87% of the laboratory's sales.

The analysis by geographic region highlights satisfactory growth
in all markets, with the "Other EU countries" region continuing to
drive Group growth under the effect of the significant increase in
Oralair(R) sales in Germany.

Changes in financial position and significant transactions and
events of the quarter

The financial position improved: cash net of debt was largely
positive at 31 March, whereas it was negative at the same time last
year.

Preliminary results of the Oralair(R) grasses trial in the US
should be obtained and released before the end of April.

Outlook for the current financial year

The good first quarter results confirmed the guidance for
full-year sales growth in excess of 8%, featuring further improvement
in profit margins.
