6 Innovation Driving Value Transgenomic’s Diagnostic Tools offer both established and cutting - edge technologies defined by their best in class sensitivity and comprehensive scanning ability for detecting mutations

Why Are Mutations Important? Many Serious Diseases Are Driven by a Change in Protein Structure

…In Cancer 8 Cancer is a Progressive Genetic Disorder Mutation Disease Progression Treatment Challenges Ultra - sensitive DNA Detection Heterogeneity of cancer demands highly sensitive mutation scanning methods for early detection of important genetic changes

» WAVE ® , SURVEYOR ® Scan, BLOCker™ - Sequencing and ICE COLD - PCR are breakthrough methodologies that enhance the ability of Sanger sequencing to detect and identify mutations at or significantly beyond the levels achieved with allele - specific probes or next generation sequencing » SURVEYOR Scan kits can be run on multiple platforms → Ability to meet any research or testing need » BLOCker - Sequencing and ICE COLD - PCR are run on standard Sanger sequencing equipment found in most molecular labs » Cost Containment: → No need for fluorescently labeled nucleotides or probes → No need to test for specific mutations Technologies with Broad Appeal 9

10 WAVE ® System High sensitivity mutation detection instrument; leading system for BRCA analysis in Europe and Asia

11 SURVEYOR ® Mutation Detection Mismatch endonuclease that identifies both presence and location of a mutation Long fragments Short fragments Uncut strand

Conventional versus COLD - PCR 12

ICE COLD - PCR I mproved and C omplete E nrichment CO amplification at L ower D enaturation temperatures – PCR • Patented enhancement to COLD - PCR demonstrating reproducible detection at very high analytic sensitivity (100 to 1000 fold over “normal” Sanger sequencing) for detection of DNA in blood and body fluids • Specifically enhances amplification of mutated DNA • Application to detection of cancer gene mutations for early diagnosis of disease, monitoring of disease, recurrence and therapeutic response • Exclusively licensed from Dana Farber for Sanger sequencing and pyrosequencing, non - exclusive for RT - PCR, next gen sequencing Several collaborations beginning to further validate ICE COLD - PCR 13

BLOCker™ - Sequencing BLOCker - Sequencing: BL ocking O ligonucleotide C ycle Sequencing • BLOCker - Sequencing is Transgenomic’s patented approach which selectively blocks the sequencing of wild - type DNA and allows samples with lower concentrations of mutant DNA to be sequenced for any mutation within a target DNA sample • Enhances the limit of detection of standard Sanger sequencing by 10 - fold • Enriches for direct sequencing of mutated DNA over wild - type (unmutated DNA) 14

15 Value of ICE COLD - PCR/ BLOCker • Combined techniques offer the highest sensitivity mutation detection capability in the marketplace • Automation and multiplex capable • Runs on standard Sanger sequencing instrumentation without any changes – Most labs worldwide already have Sanger equipment – Exceeds sensitivity of Next - Gen platforms • BLOCker can be applied to tumor testing or combined with ICE COLD - PCR to increase sensitivity • ICE COLD - PCR permits mutation testing on blood and Circulating Tumor Cells (CTC’s)
