modalities for opioid addiction. We feel this product will address one of the
major health issues in the US and I am looking forward to establishing a strong
organization to execute the launch of Zubsolv in a market with significant
growth potential," said Robert A. DeLuca, President of Orexo US Inc.

Orexo's extensive knowledge in sublingual technologies. Zubsolv is intended for
maintenance treatment of people suffering from opioid dependence. Through
application of its proprietary technologies Orexo has increased the
bioavailability of the active ingredient, accelerated dissolve time, reduced
tablet size and improved taste. In a comparative acceptability study 9 out of 10

treatment. Zubsolv has the potential to be the leading product on a growing USD
