3. Raptor Company Profile • Raptor develops protein therapeutics for the treatment of neurodegenerative brain diseases and cancer. • Core competencies in protein bioengineering, receptor biology, non-clinical and clinical development in both protein and small molecule therapeutics

4. Corporate and Financial History • September 2005 - Co-founders Christopher M. Starr, Ph.D. and Todd C. Zankel, Ph.D. form Raptor Pharmaceutical Inc. • January 2006 - Asset Acquisition Agreement signed with BioMarin transferring $16M worth of RAP technology, IP and know-how to Raptor • March 2006 - Raptor raises $300K of seed funding, hires CFO Kim Tsuchimoto, signs facilities lease, and begins PIPE financing effort based on reverse merger • May 25, 2006 – Raptor completes reverse merger and finalizes $5M PIPE (Yahoo: RPTP.OB)

5. Presentation Outline • Opportunities • The Science • NeuroTransTM • Cancer indications: AmpTideTM and HepTideTM • Corporate and Project Goals • Corporate Structure and Financials • Summary

6. CNS Therapeutic Markets are Huge • 13.3-16.1 million individuals in the US are afflicted with CNS disorders; 1.2 million more diagnosed in US each year • Alzheimer’s Disease, Parkinson’s Disease, Multiple Sclerosis and Amyotrophic Lateral Sclerosis (ALS) markets collectively estimated at $30-50B WW, growing at 14% annually • Medical Community is unprepared for the growing wave of unmet medical need and social costs associated with these diseases: second therapeutic wave for baby boomers

7. CNS Therapeutic Markets are Large and Growing CNS disorders currently cost the US economy over $600 billiondollars annually in supportive care. “Any effective treatment or cure that can reduce the rapidly growing financial burden of neurodegenerative disorders and assist the elderly in maintaining independent living arrangements will be a major revenue producer for its developers and distributors”. AdvanceTechnology Monitors – Novel Approaches to Neurodegenerative Disorders.

8. Many CNS Therapies are Stalled in ClinicalDevelopment The clinical failure of many potential CNS therapeutics is not due to a lack of drug potency, but rather to lack of an effective CNS delivery system. "There was a great deal of hope for GDNF and there still is a great deal of interest in finding different ways to provide it to the brain.” Dr. Anthony Lang, Director of the Movement Disorders Center at Toronto Western Hospital in Canada. “By 2007, drug delivery will account for 39% of all pharmaceutical sales” John Waslif, analyst with UK research firm, Visiongain

9. Science Vision To employ the tissue targeting potential of a class of receptor chaperone proteins, represented by Receptor-Associated Protein, RAP as: • NeuroTransTM - Targeted delivery of therapeutics to the brain and other tissues • AmpTideTM and HepTideTM -“First in class” targeted cancer therapeutics

10. Receptor-Associated Protein (RAP) • 37kDa human protein • RAP has a normal function in receptor biosynthesis for lipoprotein receptor synthesis • Binds to lipoprotein receptors on cell surfaces • Lipoprotein receptors are the therapeutic targets for RAP

11. RAP Receptors are Found in Most Tissues Examples of lipoprotein receptors in contact with blood LRP 1 LRP2, Megalin VLDLR LRP5/6

12. Therapeutic Applications CANCERTHERAPIES CNS DISEASES RAP THERAPEUTIC PLATFORM METABOLIC DISEASES VACCINES

17. Selected Members of Lipoprotein Receptor Family Receptors on the BBB Nature Cell Biology   October 1999 volume 1 issue 6 pp E157-E162 DOI:10.1038/14109

18. RAP cDNA Protein Therapeutic cDNA Standard Bacterial or Mammalian Cell Production How are RAP-Drug Fusions Made? RAP- drug fusion protein

19. RAP fusion injected into blood How Does RAP Deliver Drugs to the Brain? RAP receptor Blood Brain Barrier

20. RAP is Rapidly Transported Across the Blood-Brain Barrier Vd (μL/gm) Pan, W. 2004 JCS 117:5071

21. RAP Linked to Brain Growth Factors: Partnering Opportunities

22. Approaches to Delivering Therapeutics Across the BBB • Pharmacological • Lipophilic agents, nanoparticle technology, glycomimics, phospholipid microparticles - small synthetic molecules • Neurosurgical and invasive approaches • Polymer wafer implants, catheter-based pump and direct intrathecal administration, BBB disruption - chemotherapeutics • Physiological - potential BBB protein transporters - Company • Transferrin/Insulin systems – Armagen • Bacterial protease inhibitor – Angiochem • Modified Diphtheria toxin – toBBB • RAP based NeuroTransTM - Raptor
