CEO’s comments
During the third quarter we reached an important milestone when we submitted an
application for the registration of Zubsolv™ (OX219) to the U.S. Food and Drug
Administration, FDA. Zubsolv is a product for the treatment of opioid
dependence. Thanks to a great effort by our co-workers, we managed to do this
five months earlier than originally planned, which I am very impressed by.

There is a considerable market potential for Zubsolv in the USA, in a fast
growing market. Zubsolv has several important patient friendly properties which
make the tablet easy to use (such as rapid dissolution and smaller tablet size).
We believe Zubsolv to be competitive product and anticipate that we can take
considerable market shares and achieve sales of up to 500 million dollars a
year. The launch of Zubsolv is planned for the third quarter of 2013. In order
to strengthen Zubsolv’s competitiveness, we have initiated a new development
program to further differentiate our product from those of our competitors.

However, besides the very interesting prospects with Zubsolv, as previously
announced we entered into a new agreement with ProStrakan regarding Abstral®
during the second quarter. The agreement has strengthened Orexo financially and
we will regain the Abstral product rights in the USA during the first quarter of
2013. Our future presence in the USA will thus be based on Orexo offering the
market two attractive products – Zubsolv and Abstral. We have engaged Guggenheim
Securities, LLC as a financial advisor to explore different strategic
alternatives for commercialization in the USA. Based on the analysis, we will
announce at the end of this year how our commercialization plan for the USA will
be designed. As a consequence of this ongoing strategic review, the buyback of
shares will not be restarted now.
