We believe that Contrave is possibly the first treatment for obesity to address a second site, the reward system in the brain that controls food preference and food cravings. In clinical trials, Contrave has initiated and sustained significant weight loss over one year of treatment (approximately 8.0% - 10.7% in patients completing 48 weeks of therapy) by reducing appetite, increasing metabolism [0]and allowing the body to continue losing weight by offsetting its natural tendency to fight back and slow down the weight loss process. We expect to receive data from the first of our Contrave Phase 3 trials in January of 2009 and the remaining three trials by mid next year.

About Empatic(TM)

Empatic is a fixed dose combination of bupropion SR with our proprietary sustained release formulation of zonisamide. Research indicates that zonisamide inhibits AgRP, a system associated with increasing appetite while bupropion increases metabolism. Based on the strength of these results and the unique Empatic mechanism of action, the Company selected this product combination to complement our Contrave clinical development program.
