Dear UNS holders,

I would like know if somebody can clarify one issue.

Obviously UNS need more than never one agreement like.,.. they give x money in advance and UNS give preference and exclusevity in such drug.

Sanofi if I understand has the right to exercise his rights until 2014. The question is

How can somebody give today something in advance :

a) without have the final test aproved(the one that demands 18-24months)

b) the other products that UNS develop this past year also need to have this trial period of 18-24 months ?

I will appreciate know your thoughts about

Thanks

Cato
