© 2019 Tonix Pharmaceuticals Holding Corp. 9 Potential Therapeutic Advantages of Tonmya Tonmya is believed to treat PTSD by improving sleep quality • The brain naturally processes memories during sleep • PTSD sufferers’ emotionally charged memories disturb sleep and disrupt the natural processing of memories during sleep • Tonmya is believed to normalize memory processing and facilitate extinction consolidation (breaking the link between “triggers” and PTSD symptoms) Tonmya is NEITHER a benzodiazepine nor a narcotic • The active ingredient of Tonmya , cyclobenzaprine, does NOT interact with the same receptors as traditional hypnotic sleep drugs associated with retrograde amnesia; is NOT an opiate Tonmya is non - addictive • Cyclobenzaprine is the active ingredient of an orally ingested immediate release tablet (Flexeril ® ), approved 40 years ago • Flexeril’s current labeling indicates no abuse and dependence concern at higher doses than Tonmya ( 15 - 30 mg/day v. 5.6 mg/day ); NDA can be filed without drug abuse and dependency assessment studies Once - daily sublingual dose taken at bedtime enhances patient adherence

© 2019 Tonix Pharmaceuticals Holding Corp. 12 Retrospective Comparison of Time Since Trauma in P201/AtEase versus P301/HONOR (Tonmya 5.6 mg Groups) P301 study was initiated approximately two years later than Phase 2 P201 • The median time since trauma in Phase 3 was 9.5 years compared to the median time since trauma in Phase 2 of 6.0 years for TNX - 102 SL 5.6 mg treated groups

© 2019 Tonix Pharmaceuticals Holding Corp. 13 Sustained Remission in Phase 2 and Phase 3 Studies: Retrospective Analyses of P201 Entry CAPS - 5 ≥33 and P301 ≤9 Years Since Trauma Subgroups Remission is a clinical state that is essentially asymptomatic In order to confirm remission: • Determined rates of participants who met remission status at both Week 8 and Week 12 Rate of remission in ≤9 years since trauma group in P301 is similar to baseline CAPS - 5 ≥ 33 group in P201 1 1 Majority of P201 participants were ≤ 9 years since trauma and ~80% of P201 participants and all of P301 participants were ≥ 33 CAPS - 5 at baseline

© 2019 Tonix Pharmaceuticals Holding Corp. 14 Adverse Events (AEs) in P201/AtEase and P301/HONOR Studies No serious or unexpected AEs in P201 or P301 related to Tonmya • Systemic AEs comparable between studies and also consistent with those described in approved oral cyclobenzaprine product labeling • Severity and incidence of oral hypoesthesia (oral numbness) are not dose related and similar in both studies # only adverse events (AEs) are listed that are at a rate of ≥ 5% in any TNX - treated group *no values in a row for either study means the AE in the active group(s) in that study was at a rate of <5%
