Adaptimmune Positioned for Delivery in 2017/18 Three wholly-owned INDs open (MAGE-A10, -A4 and AFP) in 8 tumor types Momentum in patient screening and recruitment Initial data likely 2H 2017 and 1H 2018 Significant progress with NY-ESO* program Plan to initiate registration study around end 2017, subject to regulatory process Initial data from MRCLS, NSCLC and ovarian studies likely 2H 2017 and 1H 2018 Initiation of combination study with Keytruda® Operations funded through late 2019 3 * Under option to GSK

Nearly all proteins are available to TCRs Potentially unlimited targets; utilizes the T-cell’s native receptor Affinity tuned SPEAR TCRs overcome low target expression; required to address solid tumors Access to extra- and intracellular proteins CAR-T vs TCR: Differences in Access to Human Proteome TCRs CAR-T Better Access to Peptides with T-cell Receptors Only ~28% of proteins available to CAR-T cells Chimeric antigen receptor; not designed to recognize an HLA peptide Mostly limited to extracellular proteins Limited targets compared to TCRs 4

T-cells Play Critical Role in Cell-Mediated Immunity Cells display status by presenting peptides on their surface using HLA molecules Peptides in peptide-HLA complexes change if cell is damaged, cancerous or infected T-cells generally only recognize different “non-self” cells due to thymic selection T-cell recognition based on affinity of the TCR to the target peptide-HLA complex Multiple TCRs bind target peptide-HLA, which cluster to form an immune synapse T-cells release cytolytic granules, inducing target cell death However, T-cells have trouble recognizing cancer cells as targets Cancer peptides are derived from normal, “self” proteins Thymic selection deleted T-cells with high affinity to “self” proteins including cancer peptides Cancer cells express a lower number of targets 5 TCRs Eliminate Damaged/Diseased/Foreign Cells, but Cancer Evades Detection

Affinity Optimization is Critical to Address Majority of Antigens Adaptimmune is the Only Company with this Proprietary Technology T-cells bind to targets on cancer cells Cancer downregulates targets to avoid detection Most naturally occurring anti-tumor T-cells are low affinity (require more targets) SPEAR T-cells are affinity enhanced to overcome this problem Proprietary preclinical engineering ensures tumor-specific response Optimal specificity and affinity for antitumor activity Demonstrated efficacy in solid tumors 6

Developing Novel TCR Therapies Utilizing Proprietary Technology Platform to Develop Multiple Approaches Cancer Testis Antigens Largely exclusive to tumor tissue; shown to be good targets Developing a franchise with overlapping expression profiles Examples: NY-ESO, MAGE-A10 & -A4 Non-CTA Targets Includes oncofetal proteins and differentiation markers Closely associated with single tumor types Example: AFP Multiple HLAs Expanding research efforts to target multiple HLAs Looking beyond foundational data in HLA-A2 Next generation SPEAR T-cells Data on dnTGF-β receptor construct at SITC 2016 Also evaluating combination approaches 7
