© 2020 Tonix Pharmaceuticals Holding Corp. 7 COVID - 19 Vaccine Landscape • We expect more than one vaccine will be approved by FDA • Different vaccines for different individuals • More than 150 vaccines in development • Diversity of approaches is important since protective immunity is not yet understood • Technologies range from never tested before to 220 years old • Uncertainty exists around efficacy, durability and importantly, safety • Live attenuated vector systems in development include: • Tonix (horsepox), Tonix (bovine parainfluenza), Merck (measles 1 - and VSV 2 - based), Zydus Cadila (measles - based) 1 Measles - based vaccine, acquisition of Themis, collaboration with Institute Pasteur 2 VSV = vesicular stomatitis virus; collaboration with IAVI = International AIDS Vaccine Initiative

© 2020 Tonix Pharmaceuticals Holding Corp. 9 Why Use a Horsepox Platform for a Vaccine? Horsepox can be engineered to express foreign genes • Lack of persistence or genomic integration in the host • Strong immunogenicity as a vaccine • Readily manufacture at scale • Live, attenuated vaccine – direct antigen presentation Potential advantages of horsepox over vaccinia • Maintains strong immunogenicity with potentially improved tolerability • Relative to non - replicating vaccinia, horsepox’s replication in human cells provides direct antigen presentation, which is expected to trigger a T cell immune response, by Class I Major Histocompatibility Complex (MHC) Antigens • Horsepox may behave differently than vaccinia as a vector, in part because of its different repertoire of genes that modulate immune responses and host range
