Senesco’s Gene Regulation Platform Technology » C linical stage biotech company specializing in cancer » P roprietary gene regulation technology eliminates cancerous cells and protects healthy cells from premature death » The company is running a Phase 1b/2a trial with a product that treats B - cell cancers (which include multiple myeloma and non - Hodgkins B - cell lymphomas ) » Trial sites include the Mayo Clinic and the Fred Hutchinson Cancer Research Center

Senesco’s Platform A novel therapeutic approach based on gene regulation 4

Senesco’s Platform Targets B - cell Cancers » Multiple myeloma is an incurable cancer of plasma cells – “B - cell” cancer » Diffuse large B - cell lymphoma (DLBCL) is the most commonly diagnosed lymphoma » Mantle cell lymphoma (MCL) is an aggressive tumor with poor outcomes 5 All orphan drug indications

Large Market & Unmet Medical N eed » Multiple myeloma market projected at $6B by 2018 • Revlimid ( lenalidomide ) and Velcade ( bortezomib ) are most important approved drugs » B - cell cancers together are well in excess of $10B

Turning on a Normal Process » Lysine Protein – need to turn up ▪ Activates programmed cell death ( apoptosis) » Hypusine Protein – need to turn down ▪ Stimulates cell growth » Senesco’s drug candidate SNS01 - T reprograms the cells to recognize the death message by modulating the levels of both proteins 7

SNS01 - T comprises three components 1. RNAi suppresses pro - survival hypusine form 2. DNA plasmid makes stable death message under control of B - cell specific promoter 3. Polymer (PEI) forms nanoparticle to protect RNA and DNA and deliver death message to target SNS01 - T nanoparticle ~ 40 x 70 nM 8 SNS01 - T Uses Nanotechnology

Clinical Trial Status

First In - human Phase 1b/2a Study Design » Relapsed or refractory MM, MCL or DLBCL » Open - label dose escalation » Four dose cohorts – 0.0125, 0.05, 0.2 and 0.375 mg/kg » Twice weekly I.V. infusion for 6 consecutive weeks » Data have been monitored, study ongoing Primary objectives » Evaluate the safety and tolerability of multiple escalating doses of SNS01 - T Secondary objectives » Pharmacokinetics » Tumor response markers • M protein, % plasma cells » Time to relapse or progression

Efficacy – Treatment Effects in Cohort 3 Pt Infusions Disease Outcome 43 - 004 12 DLBCL Progression at 6 weeks Died 3 weeks later of progression 43 - 005 4 plus 8 at 0.05 mg/kg DLBCL Stable at 3 weeks and at 6 weeks Dose reduction 46 - 001 12 MM Stable at 3 weeks and at 6 weeks; Progression at 10 weeks 44 - 002 12 MM Stable at 3 weeks; Progression at 6 weeks » Stable disease after 6 weeks of therapy in 2/4 patients in cohort 3 » Cohort 4 dose showed significant activity in preclinical models

Overview of Study Results » Cohorts 1 - 3 completed » No dose limiting toxicities to date » The most frequent adverse events are infusion reactions and thrombocytopenia » 2/4 patients in cohort 3 had stable disease after 6 weeks of therapy » Dose escalation to 0.375 mg/kg (cohort 4)

Clinical Development Plans 13 ▪ Topline results of Phase 1b/2a in 1H - 2014 ▪ Phase 2 initiation planned for 2H - 2014 • Focus on multiple myeloma, mantle and diffuse large B - cell lymphomas
