Press Release May 23rd, 2011 at 07:30 PM

In accordance with its press release dated 26th February 2010 relating to the results of the issuer bid for the repurchase of its shares, RADIALL has continued its representations with the purpose to be removed from the Euronext Paris market.

So far, this purpose could not have been reached, since the financial market operator has refused to give a favourable answer to RADIALL‘s request until now.

Therefore, RADIALL recently took the initiative to sue Euronext Paris SA before the Commercial Court of Paris so as to instruct Euronext Paris SA to proceed with the removal as soon as possible, justified by the limited free floating shares.

Indeed, RADIALL considers its free floating shares must be measured without taking into account blocks of shares over five per cent (5%) (as for an initial public offering or for the setting of indexes), knowing that this figure has always been lower than five per cent (5%) over the last twelve months.

Alternatively, RADIALL applied to the judge for damages in consideration of the prejudice it would suffer if Euronext Paris continues, contrary to expectations, to refuse the removal from the Euronext Paris market, considering that the repurchase of its own shares represented an amount of roughly

21.7 millions Euros, as stated in the press release dated 14th April 2011.
