Novavax, Inc., announced on 31 July 2013 that the public tender offer for
Isconova AB (publ) was declared wholly unconditional and that it will be
completed. Novavax, Inc., controlled after the initial acceptance period shares
representing approximately 97.4 per cent of the shares and votes in Isconova AB

the remaining shares in Isconova AB (publ).

(publ) are delisted from NASDAQ OMX First North Premier.
