© 2020 Tonix Pharmaceuticals Holding Corp. 3 Tonix Pharmaceuticals: Lead Programs In Phase 3 clinical development of TNX - 102 SL 1 for two different conditions: • Posttraumatic Stress Disorder (PTSD) – Phase 3 study enrolling • Fibromyalgia – Phase 3 study enrolling PTSD milestones ( Phase 3 RECOVERY study ): • 1 st Quarter 2020 - Interim analysis results • 2 nd Quarter 2020 - Topline data expected Fibromyalgia milestones ( Phase 3 RELIEF study ): • 2 nd Half 2020 - Interim analysis results expected • 1 st Half 2021 - Topline data expected 1 TNX - 102 SL (cyclobenzaprine HCl sublingual tablets) is an investigational new drug and has not been approved for any indication
© 2020 Tonix Pharmaceuticals Holding Corp. 4 TNX - 102 SL TNX - 102 SL • Novel sublingual formulation of cyclobenzaprine HCl 1 designed for long - term daily use at bedtime • Rapid absorption • Transmucosal absorption bypasses first pass liver metabolism • Dynamic pharmacokinetic profile with increase in cyclobenzaprine concentration during sleep induction and decrease leading up to awakening • Cyclobenzaprine is the active ingredient of oral (swallowed) muscle relaxants, Flexeril ® and Amrix ® TNX - 102 SL is believed to treat PTSD and fibromyalgia by improving sleep quality, in contrast to sleep quantity • Quality involves restorative properties of sleep • Quantity is time spent asleep • TNX - 102 SL targets clinical conditions for which improved sleep quality may have a therapeutic benefit • Reduction in disease - specific symptoms with sleep improvement as a secondary endpoint 1 Cyclobenzaprine is the active ingredient of oral (swallowed) muscle relaxants, Flexeril ® and Amrix ®
© 2020 Tonix Pharmaceuticals Holding Corp. 5 Potential Therapeutic Advantages of TNX - 102 SL Cyclobenzaprine, active ingredient of TNX - 102 SL, is NEITHER a benzodiazepine nor a narcotic • Does NOT interact with the same receptors as traditional hypnotic sleep drugs associated with retrograde amnesia and is NOT an opiate TNX - 102 SL 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 TNX - 102 SL (15 - 30 mg/day v. 5.6 mg/day) • TNX - 102 SL NDA can be filed without drug abuse and dependency assessment studies Other desirable features of TNX - 102 SL include • Once - daily sublingual dose taken at bedtime is expected to enhance patient adherence • Rapid, transmucosal absorption aligns bioavailability of drug with sleep cycle • Sublingual formulation bypasses first - pass hepatic metabolism and reduces exposure to long - lived active metabolite of cyclobenzaprine associated with negative side effects
© 2020 Tonix Pharmaceuticals Holding Corp. 6 Potential Role of Sleep Quality in PTSD and Fibromyalgia PTSD • The brain naturally processes memories during sleep • PTSD sufferers’ emotionally charged memories disturb sleep and disrupt the natural processing of memories during sleep • TNX - 102 SL is believed to normalize memory processing and facilitate extinction consolidation (breaking the links between “triggers” and PTSD symptoms) • TNX - 102 SL improved sleep quality in two prior PTSD studies (Phase 2 and Phase 3) indicated by improving scores on the PROMIS sleep disturbance scale Fibromyalgia (FM) • Pain is a sensor system in the brain; when the system malfunctions, the pain alarm is turned on even through there has been no peripheral nerve tissue injury • Improving sleep quality is believed to reduce pain and fatigue in FM, suggesting sleep dysfunction is pathogenic in FM • TNX - 102 SL acts as a non - opioid, centrally - acting analgesic to aid in the management of FM

© 2020 Tonix Pharmaceuticals Holding Corp. 11 Memories are Processed During Sleep • Memory consolidation occurs primarily during sleep 1,2 • The main brain regions involved in emotional memory processing are the prefrontal cortex, amygdala, and hippocampus 2 - 4 1. Hanert A, et al. J Neurosci . 2017;37(50):12238 - 12246. 2. van Marle, H. Eur J Psychotraumatol. 2015;6:27633. 3. Kitamura T, et al. Mol Brain . 2014;7:13. 4. Bocchio M, et al. Neuron. 2017;94(4):731 - 743. Memory Consolidation • Memories are initially stored in and retrieved from the hippocampus 2,3 • Emotional aspects of memory are processed and stored in the amygdala 2,3 • During sleep, memories from the hippocampus are transferred to the prefrontal cortex ; the amygdala decouples the emotional charge from the memory 1 - 4
© 2020 Tonix Pharmaceuticals Holding Corp. 12 In PTSD Trauma Memories Are Not Consolidated • Crucial brain regions and circuits become impaired in PTSD, so emotional memories are not properly consolidated 1 - 4 Memory Processing in PTSD • Memory traces are not properly processed, and remain “trapped” in subcortical areas 1 • The memory stays linked to the emotional charge and fear associated with the traumatic event 1 • Memories become involuntarily retrieved; lacking autobiographical context, the memory can feel like it’s happening in the present 1 1. van Marle, H.

Curr Psychiatry Rep. 2015;17(6):41. 2. Lipinksa M, et al. J Sleep Res. 2014;23(3):309 - 317. Sleep Problems in PTSD • Abnormalities in crucial sleep states have been observed in patients with PTSD 1,2 • At least 50% of patients with PTSD report experiencing frequent nightmares 1 • Sleep disruptions shortly after trauma are predictive of later development of PTSD 1,2
