6 CNS PORTFOLIO Common Chronic Conditions are a Challenge for Pharma © 2024 Tonix Pharmaceuticals Holding Corp. Fibromyalgia is a common chronic disease 1 - 3 • Chronic pain syndrome that persists for years or decades No animal model is recognized for nociplastic syndromes or its component symptoms • Widespread pain • Fatigue • Sleep disturbance • Cognitive impairment Nociplastic symptoms are subjective • Humans need to report symptoms using scales Clinical trials measuring subjective symptoms are challenging • Placebo response is typically observed • Long - term therapy means requires long - term tolerability 1 The U.S. Centers for Disease Control defines chronic diseases as “conditions that last 1 year or more and require ongoing medical attention or limit activities of daily living or both.” www.cdc.gov/chronicdisease/about/index.htm .

7 CNS PORTFOLIO Common Chronic Conditions are a Challenge for Society © 2024 Tonix Pharmaceuticals Holding Corp. The Opiate Crisis in the U.S. was driven by mistreatment of chronic pain, which was often nociplastic pain • The epidemic of prescription pain killers was addressed by regulations which limited the availability of opiates • Mandy individuals who are opiate dependent have transitioned to illegal street heroin and fentanyl • Illegal drugs contribute to homelessness There is an unmet need for non - opiate analgesics that address nociplastic pain • No new drug for fibromyalgia has been approved since 2009

Acute Stress Reaction (ASR)/ Acute Stress Disorder (ASD) ASR/ASD are acute stress conditions resulting from trauma which can affect both civilian and military populations. Large unmet need: • According to National Center for PTSD, about 60% of men and 50% of women in the US are exposed least one traumatic experience in their lives 1 • In the US alone, one - third of emergency department visits (40 - 50 million patients per year) are for evaluation after trauma exposures 2 Current standard of care: • No medications are currently available at or near the point of care to treat patients suffering from acute traumatic events and support long - term health 1 National Center for PTSD.

78 CNS PORTFOLIO NASEM Language Highlighted by Senate Labor - HHS Appropriations Subcommittee (August 1, 2024) • Senate Appropriations Committee report on FY25 Labor, Health, and Human Services Appropriations Act includes language on Long COVID, fibromyalgia and nociplastic syndromes 1 1 FY25 Labor - HHS Senate Report, p145 - 146. Accessed Aug 7, 2024: https://www.appropriations.senate.gov/download/fy25 - lhhs - senate - report © 2024 Tonix Pharmaceuticals Holding Corp. “Long COVID Treatments. — The Committee remains concerned about the economic and overall health impact that Long COVID inflicts on the Nation. It is currently estimated that between 6 percent and 19 percent of those infected with SARS – CoV – 2 go on to develop Long COVID, resulting in up to 20 million Americans suffering from this set of debilitating chronic symptoms. Long COVID is characterized by a wide range of symptoms including severe fatigue, non - restorative sleep, cognitive dysfunction, and widespread pain. Further, it resembles other post - acute infection syndromes [PAISs], such as fibromyalgia, myalgic encephalomyelitis/chronic fatigue syndrome [ME/CFS] and related conditions, known as 146 chronic overlapping pain conditions [COPCs] or nociplastic syndromes. While the Committee is pleased that NIH’s HEAL and RECOVER initiatives plan to target some specific symptoms of Long COVID, the Committee is concerned that NIH has not expanded the evaluation of treatments to address many common symptoms associated with Long COVID either individually or that present as syndromes which are combinations of symptoms. Furthermore, NIH’s research program has defined Long COVID narrowly, excluding many of the common symptoms plaguing Long COVID sufferers. In June 2024, NASEM released the 2024 NASEM Long COVID Definition, which encompasses extensive lists of the symptoms and diagnosable conditions that current science attributes to Long COVID. The Committee urges NIH to rebalance its research program to prioritize clinical trials in pursuit of effective treatments and to use the NASEM Long COVID definition to guide its choice of symptoms and conditions to be address by the candidate treatments. Such trials should target key symptoms and symptom complexes associated with Long COVID including widespread pain, fatigue, non - restorative sleep, brain fog, dizziness, post - exertional malaise [PEM], postural orthostatic tachycardia syndrome [POTS] and loss of taste and smell. Further, the Committee urges NIH to prioritize the support of clinical trials evaluating therapies for Long COVID including therapies that have demonstrated efficacy in treating COPCs or nociplastic syndromes that overlap with Long COVID.”
