   · Net sales for clinical use of NIOX MINO/NIOX VERO increased by 12% in total despite a decrease in the US by 12% (13% in local currency) due to the remodeling of the sales force and selling process.

   · Strategic sales/shipments (sales to Pharmaceutical companies and CROs for clinical trials) decreased by 24%. These sales fluctuate substantially between quarters.

· Total worldwide number of tests sold (repeat and initial) reached almost 0.6m (0.5) tests, an increase of 14% Y-o-Y and in the US for clinical use decreased by 4%. The remodelling of the sales efforts have focused more on the placement of devices to increase the installed base.

· Total repeat test volume for clinical use increased by 20% and in the US by 16%.
