Business Description
The company is a drug discovery company that applies its two complementary technology platforms, Drug Discovery Genomics and Advanced Drug Selection Technologies, to key rate limiting steps in identifying new drugs. These rate limiting steps are the translation of genomic information not novel drug targets and the selection and identification from sources of chemical diversity of drug leads that interact with drug targets. The company's Drug Discovery Genomics platform includes proprietary gene technologies and expertise in microbial model systems used to determine the function of genes and to prioritize drug targets. The company's Advanced Drug Selection Technologies combine the steps of drug screening, chemical selection and structural analysis into an integrated process designed to identify drug leads faster than conventional methods.

Use of Proceeds
The proceeds from the proposed offering will be used for repayment of the $3 million promissory note to PerSeptive, research and development, expansion of its laboratory facilities, working capital and general corporate purposes.
