5. Company Overview Clinical stage immunotherapy company with novel ‘ImmunoBody’ DNA vaccine platform for cancer and chronic infectious diseases Lead product (SCIB1 for melanoma) entered Phase I clinical trials in June 2010 with steady progress made in 2011 -Dose increased from 0.4mg to 4mg with no serious adverse effects Follow up vaccine targeting NY-ESO-1 (SCIB2) at pre-clinical proof of principle stage (lung, oesophageal, prostate, liver, gastric, ovarian, bladder cancers) with more in the pipeline Partnerships with Ichor Medical Systems, immatics Biotechnologies GmBH and others to optimise immune response and generate new products Antibody portfolio sale to Arana Therapeutics (now Cephalon/Teva) in 2006 Milestone payment of £2.85m received in November 2011 when SC104 started Phase 1 clinical trials in USA 5

6. Industry Trends Continued trend for Big Pharma to move away from in-house R&D and to rely more on partnerships with Industry and Academia Larger Biotechs becoming more aggressive buyers of innovative companies and providing growing competition for Big Pharma Pick up in M&A deal value in 2011 (e.g. Amgen/Biovex $1 billion) Public markets still generally unsupportive of early stage Biotech (until key value inflexion point reached) Outstanding projects with future strategic value to third party will succeed 6
