© 2020 Tonix Pharmaceuticals Holding Corp. 4 COVID - 19 Vaccine Landscape • 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 • Fastest developed vaccines benefit balance speed of development with potentially short - term antibody - based protection • We expect more than one vaccine will be approved by FDA • Different vaccines for different individuals • Live attenuated vector systems in development include: • Tonix (horsepox) 1 , Tonix (bovine parainfluenza) 1 , Merck (measles 2 - and VSV 3 - based), Zydus Cadila (measles - based) 1 TNX - 1800 (horsepox/Cov - 2 spike live virus vaccine) and TNX - 2300/TNX - 2600 (bovine parainfluenza virus/CoV - 2 spike live virus vacc ines) are at the pre - IND stage of development and are not approved for any indication 2 Measles - based vaccine, acquisition of Themis, collaboration with Institute Pasteur 3 VSV = vesicular stomatitis virus; collaboration with IAVI = International AIDS Vaccine Initiative



© 2020 Tonix Pharmaceuticals Holding Corp. 5 Live Attenuated Virus Vaccines for Other Infectious Diseases 1 • Long term, durable immunity • Stimulate T cells and provide years to decades of protection • Single administration, scalable manufacturing • Low dose is amplified by replication, mRNA and protein synthesis at vaccination site • Block forward transmission (infectivity) • Key to conferring herd immunity and protecting immunocompromised 1 For example, the eradication of smallpox, containment of measles, mumps, and rubella



© 2020 Tonix Pharmaceuticals Holding Corp. 6 TNX - 1800 1 : Potential COVID - 19 Vaccine Engineered for Long - term Immunity • Based on “vaccinia” vaccine developed more than 200 years ago by Dr. Edward Jenner to prevent smallpox • Eradicated smallpox (only viral disease ever eradicated) • Elicits durable (many decades) T cell immunity • Single dose protection without adjuvants • Manufacturable at scale • Minimal “cold chain” supply issues • Glass - sparing packaging owing to small unit dose • Genetic analysis of early vaccines indicates that Tonix’s “horsepox” is closely related to Edward Jenner’s “vaccinia” • Modern “vaccinia” evolved during the 220 years it was propagated by primitive methods – for over 120 years before “viruses” were identified 1 TNX - 1800 (horsepox/Cov - 2 spike live vaccine) is at the pre - IND stage of development



© 2020 Tonix Pharmaceuticals Holding Corp. 7 Vaccinia Induces a Skin Reaction Called “Take” – Described by Dr. Edward Jenner 1. Fulginiti VA, et al. Clin Infect Dis. 2003;37(2):241 - 250. 2. Liu L, et al. Nature Med. 2010;16(2):224 - 228. 3. Centers for Disease Control and Prevention. Accessed April 15, 2020. *Example of major cutaneous reaction, or “take,” resulting from a replication - competent live - virus vaccine delivered via scarifi cation, indicating successful vaccination 1,3 5 mm Vaccine Vaccination by scarification 1 • Biomarker of protection • Smallpox was eradicated using this marker • Revaccination indicated for recipients without “take” • Measure of T cell immunity • No need for blood draws or complex laboratory studies • No other functional T cell assay is approved or in clinical use for vaccination Take



© 2020 Tonix Pharmaceuticals Holding Corp. 8 TNX - 1800 1 , a SARS - CoV - 2 Vaccine Candidate • Utilizes Tonix’s proprietary horsepox virus as a vector • Encodes a protein from SARS - CoV - 2, the cause of COVID - 19 • Developed in collaboration with University of Alberta, Canada • Animal testing with Southern Research Institute • Small animal and non - human primate testing data expected in 4Q20 • Manufacturing agreement with FUJIFILM Diosynth • Development for Good Manufacturing Practice (GMP) manufacturing for human trials • GMP 2 clinical supply expected to be ready for human trials in 2021 3 1 TNX - 1800 is at the pre - IND stage of development 2 Good Manufacturing Practice = GMP 3 We cannot predict whether the global COVID - 19 pandemic will impact the timing of these milestones



© 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



© 2020 Tonix Pharmaceuticals Holding Corp. 10 TNX - 1800 Upcoming Milestones Southern Research studies will address two key questions: • Will vaccination of animals elicit an immune response to the S protein? • 4th Quarter 2020 – Non - human primate and small animal response results expected 1 • Will immune response protect animals against a challenge with SARS - CoV - 2 virus? • 4th Quarter 2020 – Non - human primate and small animal results expected 1 Detailed analysis of primates planned, including: • Major cutaneous reaction or “take” in primates • In vitro stimulation of T cells • Neutralizing antibodies 2 1 1 We cannot predict whether the global COVID - 19 pandemic will impact the timing of these milestones



© 2020 Tonix Pharmaceuticals Holding Corp. 11 Unique Challenges of SARS - CoV - 2 SARS - CoV - 2 is more infectious, has a longer incubation time, and presents asymptomatically in more individuals, making it highly spreadable 1 The death rate for COVID - 19 is significantly lower compared to SARS. 1,2,4 However, due to its virulence, SARS - CoV - 2 has resulted in far more deaths 5 SARS Rate of infectivity 1 Incubation time 2 Asymptomatic 3 Rate of death 1,2 Deaths 2 0.4 2 - 7 days ~13% ~10% SARS - CoV - 2 Rate of infectivity 1,4 Incubation time 2 Asymptomatic 4 Rate of death 1,4 Deaths (as of Oct 2020) 5 ~2.5 7 - 14 days ~35% ~0.4% 1.

© 2020 Tonix Pharmaceuticals Holding Corp. 12 Contrasting T cell and Antibody Immunity • T cell immunity • Durable or long - lived (many years) • Recognize fragments of pathogens on the surfaces of infected cells • Cannot recognize pathogens directly • Potential to clear viral infections (by killing infected cells) • Potential to block forward transmission (contagion) by infected people • Antibody immunity • Temporary or short - lived (typically 3 - 6 months) • Recognize pathogens directly • Potential to block viral entry (by recognizing pathogens) • Can only recognize virally infected cells that express viral surface proteins



© 2020 Tonix Pharmaceuticals Holding Corp. 13 What Is the Goal of Vaccination? • Vaccination instructs the immune system how to respond rapidly upon reinfection 1 - 3 • A typical infection is a race between the virus and the immune response • Vaccination gives the body a “head start” • Most vaccines against viruses protect against serious illness , not infection 2,3 • Different vaccines work in different ways • How an effective vaccine protects against disease depends on the nature of the virus 2,3 • Blocking forward transmission (spread of infection) is essential for public health 4 1.

© 2020 Tonix Pharmaceuticals Holding Corp. 14 COVID - 19: Reason for Optimism? • Most people recover, which suggests: • Vaccines can be designed that safely mimic infection • Herd immunity can be achieved by vaccination • Vaccine developers can learn from individuals who recover • Study their immunity in detail for a blueprint of a successful immune response • Potential to block forward transmission (contagion) by infected people • Comparison to HIV: protective immunity is unknown • No vaccine developed after 35 years



© 2020 Tonix Pharmaceuticals Holding Corp. 15 Where Do We Go From Here? • Goal: Effective COVID - 19 vaccines • So we can return to work and school • Need #1 Quickly available vaccines • Even if they offer only temporary immunity -- several now in human trials • Need #2 Vaccines providing long - term immunity • Durable immunity for years • Blocking of forward transmission • Expect longer development and testing timelines



© 2020 Tonix Pharmaceuticals Holding Corp. 16 Upcoming Milestones of TNX - 1800 Program 1 © 2020 Tonix Pharmaceuticals Holding Corp. • Results from small animal and non - human primate studies, including challenge with SARS - CoV - 2, due 4Q 2020 2 • 4 th Quarter 2020 – Small animal and primate immune response results expected 3 • 4 th Quarter 2020 – Small animal and primate CoV - 2 challenge results expected 3 • Phase 1 safety study in humans expected to be initiated in 2021 3 • Clinical trial quality or “GMP” 4 vaccine development and production partnered with FUJIFILM Diosynth 1 Investigational new drug and biologic, not approved for any indication 2 Collaboration with Southern Research 3 We cannot predict whether the global COVID - 19 pandemic will impact the timing of these milestones 4 Good Manufacturing Practice = GMP
