31 Potential for long - lived memory , mediating immune surveillance GvHD risk, eliminated by knockout of T cell receptor (TCR) Greatest proliferative potential – potentially most useful for ongoing antigenic pressure Adaptive lymphocytes – capable of generating distinct functional attributes Trafficking and persistence as ‘tissue - resident T - cells’ No GvHD risk, TCR is invariant Rapid activation response and capacity for clonal expansion Bridge between innate and adaptive lymphocytes Traffic to bone marrow and secondary lymphoid tissues Little GvHD risk, naturally suppressive Less rapid and more limited expansion gives greater control over exposure – potentially more useful for short - term treatment Innate lymphocytes – most potent cytolytic capacity Century’s capability to make multiple cell types enables optimal matching of cell characteristics to indication Engineered iPSC MCBs CAR iNK cell CAR iT cell CAR αβ iT cell CD4 CD8 The right cell for the right indication(s) MCB: Master Cell Bank GvHD: Graft vs Host Disease

32 Precision CRISPR MAD7 - mediated sequential gene editing of iPSCs generates uniform product candidates Multiple gene edits (KO/KI) iPSC Engineered iPSC Master C ell Bank (MCB) Sequential selection steps iPSC Precision Engineering CRISPR - mediated HDR (MAD 7) Advantages of Century’s Platform Precise CRISPR - mediated homology - directed repair 1 reduces off - target integration Successive and efficient gene editing through iPSC platform avoids risky multiplex modification and structural variants • Allo - Evasion edits • Protein and cell engineering Quality control through generation of homogenous MCB establishes genomic product integrity Manufacturing begins at the MCB, confirmed to be free from genetic aberrations 1.
