CEO’s comments

It is a pleasure to report on the achievements for 2013, which has been a year
of tremendous transformation. The major highlights we achieved include approval
of Zubsolv for sale in the US, establishment of manufacturing and a commercial
subsidiary in the US, and finally that we launched Zubsolv in the US market.
Although we just have commenced the launch of Zubsolv, I am pleased with the
continued positive sales development and our improving market access position.
We have laid the foundation for a successful 2014 - and by further improving our
contracts with private and public insurance providers the coming year will aid
to secure a commercial success of Zubsolv.

The key factor for future success on the US market is to secure competitive
market access for Zubsolv, i.e. contracts with private and public insurance
providers to ensure access and preferential reimbursement. The first
improvements came in November and December and I expect that Zubsolv will
continue to improve the competitive position in the months to come. The
implementation of the contract with CVS Caremark becomes effective as from
January 1st this year and we have already achieved similar terms and conditions
with Medimpact. This means that patients with restrictive insurance plans in
these programs can only choose Zubsolv or generic products as of January 1,
2014. The effect of the improved reimbursements and the targeted sales efforts
could already be seen at the end of December, and I am pleased to see gross
sales increased by more than 60 percent during the first full week of January
and the amount of tablets sold doubled during the first two weeks of January.

Another major factor that will determine the commercial success of Zubsolv is
the product awareness amongst prescribers, our ability to sell Zubsolv to the
doctors against the competing products, and our success in developing Zubsolv
further through comprehensive investments into life cycle management activities.
In order to take advantage of the improved market access, our commercialization
partner Publicis Touchpoint Solutions will expand its sales organization at the
end of January. This expanded organization will primarily concentrate on areas
where there are a high percentage of patients with a favorable price coverage
and reimbursement for Zubsolv.

Our other key product, Abstral, continued to develop positively during 2013 in
Europe and towards end of the year also in the US. The US partner for Abstral,
Galena Biopharma Inc., has already demonstrated that they can drive market share
growth, as Abstral reached about five percent share of total prescription in the
beginning of 2014 – 7 months from the contract was signed. Abstral was also
approved and launched in Japan by Kyowa Hakko Kirin during the year and we look
forward to a similar success on this market.

In 2013 we decided to undertake significant investment in clinical trials and to
establish manufacturing processes and substantial inventories of Zubsolv in
relation to the launch. I am looking forward to a 2014 where we will leverage
these investments to drive the success of Zubsolv. In the coming year we will
have a high focus on driving sales of Zubsolv, complete the initiated life-cycle
management initiatives, and secure optimal management of the working capital to
develop a profitable Orexo. The united Swedish and US colleagues of Orexo are
fully committed to secure the commercial success of Zubsolv.
