© 2020 Tonix Pharmaceuticals Holding Corp. 9 Relationship Between Horsepox, Certain Vaccinia Strains and Variola Legend: Alignment of orthopoxvirus genomes and location of horsepox (HPXV) genes within telomeres. Orthopoxvirus genomes were aligned using the program GView ( https://server.gview.ca ). The actual nucleotide sequence of each gene within the genome was compared to the coding sequence (CDS) of each gene within the horsepox (HPXV) reference genome (NCBI Accession DQ792504) and the following orthopoxvirus genomes (VACV Mulford 1902 - MF477237; VACV Lister - AY678276; VACV ACAM2000 - AY313847; VACV Copenhagen - M35027; VACV IOC - B141 - KT184690; VACV TianTan - KC207810; Rabbitpox virus (RPXV) Utrecht - AY484669; MVA - BN - DQ983238; VACV LC16m8 - AY678275 ; Variola virus (VARV) (Bangladesh 1975 - L22579). The white gaps in the HPXV reference sequence represent non - coding sequences within the genome. The percent identity (PID) cutoff was set to 85%, meaning that only matches with PID values over 85% are displayed. Abbreviations: BLAST = Basic Local Alignment Search Tool; LITR = left inverted terminal repeat (ITR); RITR= right ITR.

© 2020 Tonix Pharmaceuticals Holding Corp. 10 Development of TNX - 1800 as a COVID - 19 Vaccine Collaboration with Southern Research • Southern Research will develop and test TNX - 1800, which is designed to express Spike (S) protein from the virus that causes COVID - 19, which is called SARS - CoV - 2. • We plan to test whether vaccination of animals with TNX - 1800 will elicit an immune response to the S protein from SARS - CoV - 2 and if so, whether such an immune response will protect mice and non - human primates against a challenge with SARS - CoV - 2 virus • We expect to receive data from small animal experiments and from primates in the fourth quarter of 2020 1 Further Development • The further development of TNX - 1800 for human clinical trials will require manufacturing according to Good Manufacturing Practice, or GMP • TNX - 1810, TNX - 1820 and TNX - 1830 2 are in early development as vaccines to elicit almost pure T cell responses vaccines 1 We cannot predict whether the global COVID - 19 pandemic will impact the timing of these milestones 2 TNX - 1810, - 1820 and - 1830 are experimental new biologics, at the pre - IND and pre - clinical stage of development and are not approved for any indication
