Not for publication, release or distribution, directly or indirectly, in or into
the United States, Canada, Australia, Hong Kong, Singapore, South Africa, Japan

The extraordinary general meeting resolved today to approve
the board’s resolution to issue new shares with pre-emptive rights for existing
shareholders and the holders of the company’s convertible bonds 2010/2015. The
terms for the rights issue entail that four shares entitle to subscription of
one new share at a subscription price of SEK 9 per share, which means that the
rights issue will provide Aerocrine with approximately MSEK 260[1] before
transaction costs.

The rights issue is fully covered by subscription
undertakings and underwriting commitments.

A prospectus relating to the
rights issue will be made public around 18 April 2012.
