Biotest successfully concludes 10% capital increase

Dreieich, 21 September 2007. Biotest AG, Dreieich has increased its share
capital by 10%. The 599,567 new ordinary shares and 466,666 new preference
shares were placed through an accelerated bookbuilding process and under
the exclusion of subscription rights among institutional shareholders. With
an issue price of EUR 32.70 per ordinary share and EUR 29.00 per preference
share gross issue proceeds for Biotest at a total of EUR 33.1 million.

This sum will be used to part fund the long-term bank loan provided by
Commerzbank AG for the acquisition of the plasma protein business of Nabi
Biopharmaceuticals Corp. Announced last week, the transaction is set to be
concluded by the end of 2007 following US merger control approval and the
approval of the Nabi Biopharmaceuticals shareholders.

The capital increase was significantly oversubscribed. The majority
shareholders of Biotest AG, the Schleussner family, participated in the
capital increase in accordance with its stake at the time of the
transaction. The Schleussner family therefore maintains its shareholding of
just over 50%. The remaining ordinary shares as well as the new preference
shares were placed with German and international institutional investors.
Particularly notable is the high allotment of both ordinary and preference
shares to UK investors.

Following the registration of the capital increase, the share capital of
Biotest AG totals around EUR 30.03 million. This sum is divided into
6,595,242 ordinary shares and 5,133,333 non-voting preference shares. The
remaining subscribed capital amounts to around EUR 0.69 million. Biotest
was supported in the transaction by the Frankfurt-based investment bank,
equinet.
