SILENOR for Insomnia. According to the American Psychiatric Association, approximately one-third of adult Americans (approximately 73 million people) are affected by insomnia. One study has found that fewer than 15% of those who suffer from insomnia are treated with prescription medications. We are developing SILENORtm for the treatment of insomnia and believe that SILENORtm will offer significant benefits over currently available therapies in the insomnia market. We in-licensed the patents and the development and commercial rights to SILENORtm and intend to develop the product for the U.S. market. SILENORtm is an oral formulation of doxepin at strengths of 1 mg to 6 mg. Doxepin has been marketed and used for over 35 years at dosages from 75 mg to 300 mg per day for the treatment of depression and anxiety. Doxepin has a well-established safety profile and we expect that our targeted dosages will be well tolerated and provide a wide margin of safety. SILENORtm is a potent blocker of a set of brain receptors known as H1 receptors, which are believed to play an important role in the regulation of sleep. The leading approved insomnia medications, Ambien, Sonata and Lunestatm, work by binding and activating a different set of brain receptors known as GABA receptors. Many of the GABA receptor-activating drugs are deemed to have the potential for abuse and are therefore designated by the U.S. Drug Enforcement Agency, or DEA, as Schedule IV controlled substances, which require additional registration and administrative controls. We have completed two placebo-controlled Phase II clinical trials, one in adults and one in elderly patients with chronic primary sleep maintenance insomnia, and we are currently enrolling patients in Phase III clinical trials. Based on our analysis of the results of our prior clinical trials, we believe that SILENORtm will induce and maintain sleep throughout the night, without next-day residual effects, in both adult and elderly patients. We expect initial data from our Phase III clinical trials to be available in mid-2006

In the event ProCom One fails to make any required payments or take any action required for the proper preparation, filing, prosecution or maintenance of the Patent Rights, Somaxon shall have the right to make any such required payments or take any such required action and all such payments and related out-of-pockets expenses shall be offset against and reduce any milestone and Royalty payments otherwise due from Somaxon to ProCom One pursuant to Section 4 above. 5.2 Patent Enforcement. 5.2.1 If either party should become aware of any infringement or misappropriation or threatened infringement or misappropriation of the Patent Rights, it shall promptly notify the other party in writing and provide any information available to that party relating to such alleged infringement or misappropriation. 5.2.2 Somaxon shall have the primary right, but not the obligation, to take action in its own name and its expense to secure the cessation of any infringement or misappropriation or to institute, prosecute and control legal proceedings to prevent or restrain such infringement or misappropriation concerning the Patent Rights in the Field.
