Divisional Structure Vilazodone Phase III SSRI/5HT1A

Corporate Mission Statement Emerge as the leading pure play in pharmacogenetic based services, testing and therapeutics. The Company will leverage its leading capabilities and experience in genetic marker development, validation and commercialization to provide novel, high value and proprietary diagnostics leading to more efficacious, safer and less-costly, "targeted" therapies. PGxHealth is dedicated to bringing the value of pharmacogenetic testing into mainstream clinical care to benefit providers, payers and patients.

Divisional Overview PGxHealth Division Leading position in pharmacogenetic diagnostics - strong follow on pipeline Proprietary, high-margin Therapeutic Diagnostics(tm) High-growth area of molecular diagnostics with significant ROI Targeted to payers and providers Vilazodone (SSRI / 5HT1A) Dual-acting serotonergic agent in Phase III pivotal clinical trials with plan for companion pharmacogenetic test Genetic marker test designed to increase vilazodone efficacy in target populations Cogenics Division Leading provider of pharmacogenomics and molecular services including genotyping, sequencing, gene expression and other related services Extensive domestic and international client base Clients include pharmaceutical, biotech, government, academic and agricultural firms Vital Diagnostics Division Well-established, global in vitro diagnostics business

Corporate Strategy PGxHealth Advance intellectual property and genetic marker development to commercialize scientifically valid and clinically meaningful pharmacogenetic tests (commit to 4-5 new test launches per year) Optimize vilazodone franchise: Complete first pivotal trial and identify genetic markers for vilazodone response (Q3 2007) Cogenics Grow revenue and make profitable as stand alone division Introduce cutting-edge, higher margin products to market (pain chip, LQT for clinical trials) Leverage offerings to support PGxHealth's development of genetic markers and pharmacogenetic diagnostics Vital Diagnostics Grow analyzer and reagent market penetration Improve distribution relationships Determine strategic value to company mission

Key Achievements Built seasoned management team Improved cash burn significantly Q-over-Q Vilazodone Phase III trial results expected Q3 2007 Demonstrated substantial growth in revenue from existing pharmacogenetic test LQT test revenue on track to more than double YOY Announced launch of following tests: Warfarin (October 2006) Clozapine-Induced-Agranulocytosis (January 2007) Rituximab (January 2007) Closed numerous business development opportunities: In-licensed new genetic markers relating to therapeutics response and safety in CNS, CV, Oncology and other areas that will lead to novel pharmacogenetic tests Announced landmark Pharmacare (CVS) partnership - first of its kind Introduced Long QT test into clinical trials through Quintiles partnership Established overseas distribution agreement for Long QT test - expanding distribution channels

Financial Performance Fiscal Q2 (September 30, 2006) Q4 2006 Q1 2007 Q2 2007 During last three quarters Clinical Data advances toward break-even Excluding the impact of Q2 restructuring and severance charges ($1.4M) from recent acquisitions Clinical Data approaches break-even

Vilazodone

Vilazodone Opportunity Primary Indication: Treatment of depression Market: 17 million Americans take depression drugs >$12 billion dollars in US Profile: New generation, genetically guided dual serotonergic antidepressant Mechanism of Action: Unique molecule Both Selective Serotonin Reuptake Inhibitor (SSRI) and 5HT1A partial agonist Development Stage: Phase III clinical trial in progress > 75% enrollment completed Licensed from Merck KGAA, September 2004

Vilazodone Development Plan: Milestones Discover genetic markers for response: results Q3 2007 Enrich second pivotal study with biomarkers Study targeted to be completed by year-end 2008 Conduct long-term safety study in parallel with second pivotal trial Manufacture commercial supply NDA Filing: 2009 PGxHealth to develop companion diagnostic test for vilazodone

Value of Clinical Pharmacogenetics Substantially reduces therapeutic costs and overall cost-of-care Improves patient outcomes Higher returns compared with traditional diagnostics -- leverages proprietary IP Supports quality measures and pay-for-performance initiatives Supports regulatory calls for use of pharmacogenetics in clinical care and drug labeling Creates new revenue streams for clients (as other revenue sources contract) PGxHealth is an emerging leader in commercializing pharmacogenetic tests to guide drug therapy

Pharmacogenetic Tests: Addressing Unmet Needs Current Trial and Error Treatment Approach Is Costly Pharmacogenetic tests will help physicians determine the best course of treatment faster upon diagnosis of disease Patient Response to Therapeutics Varies Widely Pharmacogenetic efficacy markers can identify those who will best respond to certain drugs Patient Safety Remains A Major Problem Pharmacogenetics safety markers identify patients most likely to develop serious adverse drug reactions
