Overview
We are awith fewer side effects and safety concerns than treatments currently available for those conditions. Our most advanced clinical-stage biopharmaceutical company committed to developingcandidates, PH94B and commercializing differentiated new generation medications that go beyond the current standard of care for anxiety, depression and other central nervous system (CNS) disorders. Our pipeline includes three CNS product candidates, each with a differentiated potential mechanism of action, favorable safety results observed in all clinical studies to date, and therapeutic potential inPH10, may provide relief from multiple CNS markets. We are currently preparing PH94B for a pivotal Phase 3 clinical study as a potential acute treatmentforms of anxiety and depression. They belong to a new class of drugs known as pherines. These investigational neuroactive steroids are formulated as nasal sprays at very low concentrations and are designed to achieve rapid-onset anti-anxiety (PH94B) or antidepressant (PH10) effects. We believe these drug candidates directly activate chemosensory neurons located in adults with social anxiety disorder (SAD), as well as additional nonclinicalthe nasal passages, which neurons then impact olfactory amygdala “fear off” (anti-anxiety) and clinical studies required to support our U.S. New Drug Application (NDA) for that indication should our Phase 3 clinical program be successful. In addition, we are planning for several small exploratory Phase 2A studies of PH94B“fear on” (antidepressant) neural circuits in adult patients, includingthe brain, without requiring systemic uptake or direct activity on CNS neurons in adjustment disorder, pre-procedural anxiety, postpartum anxiety and post-traumatic stress disorder. PH10 has completed a successful exploratory Phase 2A study for the treatment of major depressive disorder (MDD). We are currently preparing for planned Phase 2B clinical development of PH10 as a potential stand-alone treatment for MDD. In several clinical studies, AV-101 was shown to be orally bioavailable and was well-tolerated. Based on successful preclinical studies involving AV-101 alone and in combination with probenecid, we are currently planning to pursue Phase 1B, and, if successful, subsequent Phase 2A clinical development of AV-101, in combination with probenecid, for treatment of CNS indications involving the N-methyl-D-aspartate receptor (NMDAR). Additionally, our wholly owned subsidiary, VistaGen Therapeutics, Inc., d/b/a VistaStem, a California corporation (VistaStem), has pluripotent stem cell technology focused on assessing and developing small molecule new chemical entities (NCEs) for our CNS pipeline, or for out-licensing, by utilizingCardioSafe 3D, VistaStem’s customized human heart cell-based cardiac bioassay system.brain.

Our Product Candidates

PH94B Nasal Spray for Anxiety Disorders

PH94B is an odorlessa synthetic rapid-onset pherineinvestigational neuroactive steroid from the androstane family of pherines. When administered intranasally in microgram doses, PH94B activates receptors in the membrane of peripheral nasal spraychemosensory neurons connected to subsets of neurons in the olfactory bulbs that in turn connect to neurons in the limbic amygdala involved in the pathophysiology of SAD and potentially other anxiety and mood disorders. PH94B does not exert effects on receptor targets with therapeuticknown abuse potential in a wide range of neuropsychiatric indications involving anxiety or phobia. Conveniently self-administered in microgram-level doses(e.g., dopamine, nicotinic, and opiate receptors) and has neither agonistic nor antagonistic effects on GABAA α1/β2/γ2 ion channels. PH94B is pharmacologically active without requiring apparent systemic uptake and distribution to achieve its anti-anxiety effects, we are initially developingrapid-onset and short duration of anxiolytic effects.  The FDA has designated PH94B as a potential as a fast-acting, non-sedating, non-addictive new generation acuteFast Track product candidate, and we are currently developing PH94B for the treatment of anxiety symptoms in adults with SAD. SAD affects approximately 20 million Americans and, according to the National Institutes of Health (NIH), is the third most common psychiatric condition after depression and substance abuse. A personadult subjects with SAD feelsand for anxiety symptoms of anxiety or fear in certain social situations, such as meeting new people, dating, being on a job interview, answering a question in a classroom or conference room, or having to talk to a cashier in a store. Doing everyday things in frontadult subjects with adjustment disorder (AjDA).

The proposed MOA of other people - such as eating, drinking or using a public restroom – may also cause anxiety or fear. A person with SAD may also feel symptoms of fear and anxiety in performance situations, such as giving a lecture, a speech or a presentation to classmates at school, or colleagues at work, as well as playing in a sports game, or dancing or playing a musical instrument on stage.  A person with SAD is afraid that he or she will be humiliated, judged, or rejected.  The fear and anxiety that people with SAD have in social and performance situations is so strong that they feel they are beyond their ability to control. As a result, SAD gets in the way of going to work, attending school, meeting with others socially or doing everyday things in situations with potential for interpersonal interaction. People with SAD may worry about these and other things for weeks before they happen. Sometimes, they end up avoiding places or events where they think they might have to do something that will embarrass or humiliate them or cause them to be judged.  Without treatment, SAD can last for many years or a lifetime and prevent a person from reaching his or her full potential.

Three oral antidepressants are approved by the U.S Food and Drug Administration (FDA) specifically for treatment of SAD. These FDA-approved antidepressants have slow onset of therapeutic effect (often taking many weeks to months), require chronic administration and often cause significant side effects that begin soon after administration. We believe their slow onset of effect, required chronic administration and significant potential side effects and safety concerns may make these FDA-approved oral antidepressants inadequate or inappropriate treatment alternatives for many individuals affected by SAD. Our PH94B is fundamentally differentdifferentiated from all currently approved anti-anxiety medications, including the oralthree antidepressants approved by the FDA for the treatment of SAD, as well as all current anti-anxiety drugs, such as benzodiazepines prescribed off-label for treatment of SAD.
We believe PH94B-induced anxiolytic effects appear consistent with the modulation of neural circuits involved in the pathogenesis of SAD. Neurons in the limbic amygdala regulate fear and anxiety by modulating inhibitory neurotransmission in other brain regions. A microgram level intranasal dose of PH94B (3.2 micrograms) engages specific nasal chemosensory neurons which activate olfactory bulb neurons (OBNs) on the base of the brain. OBNs send neural connections to neurons in the central limbic amygdala, the brain center where fear and anxiety are regulated, resulting in downstream signaling and rapid-onset anti-anxiety effects. Importantly, PH94B does not require systemic uptake and distribution to produce its rapid-onset anti-anxiety effects. In all clinical studies to date, PH94B has not shown psychological side effects (such as dissociation, euphoria or hallucinations), sedation or other side effects and safety concerns that may be caused by the current oral antidepressants approved by the FDA for treatment of SAD, or by benzodiazepines and beta blockers, which, although not FDA-approved to treatfor treatment of SAD, are often prescribed by psychiatrists and physicians for treatment of SAD on an off-label basis. While oral antidepressants, benzodiazepinesPre-clinical and beta blockers require systemic administration to achieve anxiolytic effects, due to its unique pharmacology, PH94B does not require systemic uptake and distribution to achieve its rapid-onset anti-anxiety effects.
In a peer-reviewed, published double-blind, placebo-controlled Phase 2 clinical trial,data to date suggest that PH94B was statisticallyhas the potential to achieve rapid-onset anti-anxiety effects without systemic uptake or transport into the brain, significantly more effective than placebo in reducing both public-speaking anxiety (p=0.002)the risk of side effects and social interaction anxiety (p=0.009) in laboratory-simulated challenges of SAD patients, within 15 minutes of their self-administration of a non-systemic 1.6 microgram dose of PH94B.  Basedother safety concerns such as potential abuse, misuse and addiction associated with certain other pharmaceuticals that act directly on the results of this Phase 2 studyCNS and our recent consensus with the FDA that our initial pivotal Phase 3 study of PH94B may be conducted in a manner substantially similar to the public speakingare sometimes prescribed for anxiety component of such Phase 2 study, we are preparing for Phase 3 clinical development of PH94B as an acute treatment of anxiety in adults with SAD. Our goal is to develop and commercialize PH94B as the first FDA-approved, rapid-onset, non-sedating, non-systemic, non-additive acute treatment of anxiety in adults with SAD. We believe PH94B has potential for use on demand to treat symptoms of anxiety which result from often predictable anxiety-provoking stressors, much like a rescue inhaler is used on demand, before an asthma attack or a migraine drug is used before onset of a migraine episode. We also believe PH94B has potential to treat other anxiety-related neuropsychiatric indications, such as adjustment disorder, postpartum anxiety, preprocedural anxiety (e.g., pre-MRI), panic disorder, post-traumatic stress disorder and specific social phobias. In addition to preparing for Phase 3 development of PH94B as a potential acute treatment of anxiety for adults with SAD, we are planning for a series of small exploratory Phase 2A clinical studies of PH94B for treatment of adjustment disorder, postpartum anxiety, post-traumatic stress disorder, and pre-procedural anxiety. The FDA has granted Fast Track designation for development of PH94B for acute treatment of anxiety in adults with SAD, which we believe is the FDA’s first such designation for a drug candidate for SAD.

PH10 Nasal Spray for Depression Disorders and Suicidal Ideation

PH10 is an odorless syntheticinvestigational pherine nasal spray with potential to be a fast-actingfor the treatment for multiple neuropsychiatric indications involving depression and suicidal ideation. Conveniently self-administered in microgram-level doses without systemic exposure, we are develop PH10 asof MDD with a potential rapid-onset stand-alone treatment ofMDD.

Depression is a serious medical illness and a global public health concern that can occur at any time over a person's life. While most people will experience depressed mood at some point during their lifetime, MDD is different. MDD is the chronic, pervasive feeling of utter unhappiness and suffering, which impairs daily functioning. Symptoms of MDD include diminished pleasure or loss of interest in activities, changes in appetite that result in weight changes, insomnia or oversleeping, psychomotor agitation, loss of energy or increased fatigue, feelings of worthlessness or inappropriate guilt, difficulty thinking, concentrating or making decisions, and thoughts of death or suicide and attempts at suicide.
The most commonly-prescribed current oral antidepressants are known as selective serotonin reuptake inhibitors (SSRIs), and serotonin-norepinephrine reuptake inhibitors (SNRIs). SSRIs are intended to increase the amount of available serotonin, a neurotransmitter closely linked to mood and anxiety disorders, by inhibiting the reuptake of serotonin in the brain, preventing nerve cells from reabsorbing serotonin and reducing the levels in the brain. This means more serotonin remains available, which can sometimes improve symptoms and make patients more responsive to psychotherapy and other treatments. SNRIs similarly are intended to inhibit the reuptake of serotonin and another neurotransmitter, norepinephrine, and increase the available amounts of each in the brain. Like serotonin, norepinephrine is a neurotransmitter linked to mood.

While these medications can certainly be effective in the right context, it can be a challenge to find the right drug or combination of drugs for a particular patient. About two-thirds of patients with MDD do not respond to their initial treatment with such medications. In addition, it can take many weeks or even months to identify whether an antidepressant is working, all the while leaving a patient to cope with their depression symptoms and the potentially debilitating side effects of the antidepressants they are prescribed.
Due to their long-onset pharmacology, limited efficacy and many side effects and safety concerns, current FDA-approved oral antidepressants available in the multi-billion-dollar global depression market are often inadequate to satisfy the underserved medical needs of millions suffering from the debilitating effects of depression. Inadequate response to current medications is among the key reasons MDD is one of the leading public health concerns in the United States, creating a significant unmet medical need for new agents with fundamentally different mechanisms of action and side effect and safety profiles.
PH10 is a new generation antidepressant with a mechanism of actionMOA that is fundamentally differentdifferentiated from the MOA of all current FDA-approved antidepressants. After self-administration, a non-systemiccurrently approved treatments for MDD and other depression disorders. PH10, which is administered at microgram-level dose of PH10 bindsdoses, engages and activates chemosensory neurons in the nasal passages, connected to nasal chemosensory receptors that, in turn, activate key neural circuits in the brain that can leadproduce antidepressant effects. Specifically, PH10’s proposed MOA involves binding to rapid-onset antidepressant effects, but withoutreceptors for chemosensory neurons in the psychological side effects (such as dissociationnasal passages to regulate the olfactory amygdala “fear on” neural circuits believed to increase activity of the limbic-hypothalamic sympathetic nervous system and hallucinations) or safety concerns that maybe be caused byincrease the release of catecholamines. Importantly, unlike all currently approved oral antidepressants and rapid-onset ketamine-based therapy (KBT), including both intravenous ketamine and esketamine nasal spray, orintranasal ketamine (esketamine), we believe PH10 does not require systemic uptake to produce rapid-onset of antidepressant effects and does not cause the side effects and safety concerns of current long-onset oral antidepressants. potentially associated with KBT.

In a small exploratory Phase 2A clinical trial (n=30), PH10, self-administered at a dose of 6.4 micrograms, was well-tolerated and demonstrated statistically significant (p=0.022) rapid-onset antidepressant effects, which were sustained over an 8-week period, as measured by the Hamilton Depression Rating Scale (HAM-D), without side effects or safety concernsDecember 2022, we announced that may be caused by ketamine-based therapy and oral antidepressants. Based on positive results from this exploratory Phase 2A study, we are preparing for Phase 2B clinical development of PH10 in MDD, which preparation includes completing two additional preclinical toxicology studies required by the FDA to support our new Investigational New Drug (IND) applicationgranted Fast Track designation for proposed Phase 2B clinical development of PH10 in the U.S. With its favorable safety profile observed during clinical development to date, we believe PH10 has potential for multiple applications in global depression markets, including first as a differentiated stand-alone therapypotential treatment for MDD.

AV-101

AV-101 an Oral NMDA Receptor Antagonist for Depression and Neurological Disorders

AV-101 (4-Cl-KYN) targets the NMDAR (N-methyl-D-aspartate receptor), an ionotropic glutamate receptor in the brain. Abnormal NMDAR function is associated with numerous CNS diseases and disorders. AV-101(4-chlorokynurenine) is an oral prodrug of 7-chloro-kynurenic acid (7-Cl-KYNA), which is a potent and selective full antagonist of the glycine co-agonist site of the NMDARNMDA receptor (NMDAR) that inhibits the function of the NMDAR. Unlike ketamine and many other NMDAR antagonists, 7-Cl-KYNA is not an ion channel blocker. At doses administered in allthe Company’s studies completed to date, AV-101 has been observed to be well tolerated and has not exhibited no dissociative or hallucinogenic psychological side effects or safety concerns. With its exceptionally few side effectsconcerns, unlike several other modulators of the NMDAR. Based on observations and favorable safety profile observed in allfindings from preclinical studies, to date,we believe that AV-101, in combination with the FDA-approved drug,oral probenecid, has the potential to bebecome a new differentiated oral treatment alternative for multiple large-marketcertain CNS indications where we believe current treatmentsinvolving the NMDAR. We are inadequatepresently conducting an exploratory Phase 1B drug-drug interaction clinical study of AV-101 in combination with probenecid and expect to meet high underserved patient needs. complete dosing of the final cohort in the study in the first half of 2023.

The FDA has granted Fast Track designation for development of AV-101 as both a potential adjunctive treatment for MDD and as a non-opioid treatment for neuropathic pain.

Newly Acquired Pherines

Following the completion of the Pherin Acquisition (defined below), we now have full ownership of intellectual property rights to PH94B and PH10. In late-2019,addition, we completed a Phase 2 clinical trial of AV-101 asalso have three new early clinical-stage pherine product candidates: PH15, a potential adjunctive treatment togetherfor cognition improvement; PH80, a potential treatment for migraine and hot flashes; and PH284, a potential treatment for appetite-related disorders, each of which is further summarized below.

PH15

PH15 is an early-stage investigational neuroactive steroid pherine with potential for the acute treatment of cognitive impairment. Early functional MRI studies in human volunteers at Stanford University revealed that intranasal administration of PH15 induced rapid activation of brain areas related to cognition (Sobel et al, Brain, 1999). In a standard FDA-approveddouble blind, placebo-controlled study in human subjects, intranasal PH15 showed rapid and significant improvement in cognitive and psychomotor performance and improvement of reaction time that was better than the effect of a placebo and 2 mg of oral SSRI or SNRI,caffeine.

PH80

PH80 is an early-stage investigational synthetic neuroactive steroid with potential to engage nasal chemosensory receptor cells which in MDD patients who had an inadequate response to a stable dose of their oral antidepressant (the Elevate Study). Topline results of the Elevate Study (n=199) indicated that the AV-101 treatment arm did not differentiate from placebo on the primary endpoint (changeturn modulate neural circuits in the Montgomery-Åsberg Depression Rating Scale (MADRS-10) total score compared to baseline), potentially due to sub-therapeutic levels of 7-Cl-KYNA in the brain. As in prior clinical studies, AV-101 was well tolerated, with no psychotomimetic side effects or drug-related serious adverse events.

Our recent discoveries from successful preclinical studies of AV-101 in combination with probenecid, a safe and well-known oral anion transport inhibitor approved by the FDA for treatment of gout, suggest that there is a substantially increased brain concentration of AV-101 and its active metabolite, 7-Cl-KYNA, when AV-101 is given together with probenecid. These surprising effects were first revealed as to AV-101 and 7-Cl-KYNA in our recent preclinical studies, although the effects are consistent with well-documented clinical studies of probenecid’s ability to increase the therapeutic benefits of several classes of FDA-approved drugs that are unrelated to AV-101 and 7-Cl-KYNA, including certain antibacterial, anticancer and antiviral drugs. When probenecid was administered in combination with AV-101 in animal models, substantially increased brain concentrations of AV-101 and 7-Cl-KYNA were discovered. We also recently identified that some of the same kidney transporters that reduce drug concentrations in the blood, by excretion in the urine, are also found in the blood brain barrier and function to reduce 7-Cl-KYNA levels in the brain by pumping it out of the brain and back into the blood. In our recent preclinical studies with AV-101 and probenecid, we discovered that blocking those transporters in the blood brain barrier with probenecid resulted, as noted above, in a substantially increased brain concentration of 7-Cl-KYNA. This 7-Cl-KYNA efflux-blocking effect of probenecid,basal forebrain associated with the resulting increased brain levels and durationcontrol of 7-Cl-KYNA, suggests the potential impact of AV-101 with probenecid could result in far more profound therapeutic benefits for patients with MDD and other NMDAR-focused CNS disorders than demonstrated in the Elevate Study.
In addition, a Phase 1B target engagement study completed after the Elevate Study by the Baylor College of Medicine (Baylor) with financial support from the U.S. Department of Veterans Affairs (VA), involved 10 healthy volunteer U.S. military Veterans who received single doses of AV-101 (720 mg or 1440 mg) or placebo, in a double-blind, randomized, cross-over controlled trial. The primary goal of the study was to identify and define a dose-response relationship between AV-101 and multiple electrophysiological (EEG) biomarkers related to NMDAR function,body temperature, as well as blood biomarkers associatedpremonitory and aura symptoms of migraines.

In a small exploratory double blind, placebo-controlled exploratory Phase 2A study in women diagnosed with suicidality (the Baylor Study). We believemenopausal hot flashes, PH80 showed clinically significant improvement in the findings fromnumber and severity of hot flashes and other symptoms of menopause in the Baylor Study suggest that, subjects treated with PH80. With respect to migraine headaches,in healthy Veterans,a small exploratory Phase 2A clinical study, PH80 showed a profile compatible with the higher doserelief of AV-101 (1440 mg)the premonitory and aura symptoms of migraines.

PH284

PH284 is an early-stage investigational neuroactive steroid pherine with potential for the acute treatment of appetite-related disorders. Synthetic pherine PH284 was associatedtested in a small exploratory Phase 2A double blind, placebo controlled clinical study lasting 12 days, in patients diagnosed with dose-relatedcachexia due to terminal cancer lasted 12 days. Upon completion of a 7-day treatment period with intranasal PH284 or placebo, all patients started treatment for their underlying condition. At the end of the 7-day treatment period, PH284-treated patients showed a significant increase in the 40 Hz Auditory Steady State Response (ASSR)subjective feeling of hunger (appetite), a robust measureincreased body weight and an improved quality of life, as compared with the integrity of inhibitory interneuron synchronization that is associated with NMDAR inhibition. Findings from the Baylor Study were presented at the 58th Annual Meeting of the American College of Neuropsychopharmacology (ACNP) in Orlando, Florida in December 2019.

The Baylor Study and the results of our recent preclinical studies involving AV-101 in combination with probenecid suggest that it may be possible to increase therapeutic concentrations and duration of 7-Cl-KYNA in the brain, and thus increase NMDAR antagonism in MDD patients and individuals suffering from other CNS indications involving abnormal function of the NMDAR, when AV-101 and probenecid are combined. We are currently preparing for Phase 1B clinical development of AV-101 in combination with probenecid.
VistaStem Therapeutics – Stem Cell Technology for Drug Rescue, Cell Therapy and Regenerative Medicine
In addition to our current CNS drug candidates, our wholly-owned subsidiary, VistaStem Therapeutics (VistaStem) has developed stem cell technology-based, pipeline-enabling capabilities involving application of human pluripotent stem cell (hPSC) technologies. VistaStem’s customized cardiac bioassay system, CardioSafe 3D, has been developed to discover and develop small molecule New Chemical Entities (NCEs) for our CNS pipeline or out-licensing. In addition, VistaStem’s stem cell technologies involving hPSC-derived blood, cartilage, heart and liver cells have multiple potential applications in the cell therapy (CT) and regenerative medicine (RM) fields.
To advance potential CT and RM applications of VistaStem’s hPSC technologies related to heart cells, we licensed to BlueRock Therapeutics LP, a next generation CT/RM company formed jointly by Bayer AG and Versant Ventures and acquired by Bayer AG in 2019, rights to develop and commercialize certain proprietary technologies relating to the production of cardiac stem cells for the treatment of heart disease. As a result of its acquisition of BlueRock Therapeutics in 2019, Bayer AG now holds such rights (the Bayer Agreement).  VistaStem retains all rights to such technologies to discover and develop small molecule NCEs and certain other applications not licensed pursuant to the Bayer Agreement. In a manner similar to the Bayer Agreement, we may pursue additional VistaStem collaborations involving rights to develop and commercialize its hPSC technologies for production of blood, cartilage, and/or liver cells for CT and RM applications, including, among other indications, treatment of arthritis, cancer and liver disease.

THE PHERIN ACQUISITION

On December 20, 2022, we entered into an Agreement and Plan of Merger (the Merger Agreement) along with VTGN Merger Sub, Inc., our wholly-owned subsidiary (Merger Sub), Pherin Pharmaceuticals, Inc. (Pherin), and Kevin McCarthy in his capacity of Stockholder Representative (the Stockholder Representative), in order to acquire Pherin (the Pherin Acquisition).  The Merger Agreement provided for the Company’s acquisition of Pherin pursuant to the merger of Merger Sub with and into Pherin, with Pherin as wellthe surviving corporation. On February 2, 2023 (the Closing Date), we completed the Pherin Acquisition and Pherin is now a wholly-owned subsidiary of the Company. Immediately prior to the consummation of the Pherin Acquisition, each of Pherin’s directors and officers resigned, and no employees or other affiliates of Pherin on the Closing Date are serving or will serve in their previous roles or in any other capacity with Pherin or with the Company.

Following the completion of the Pherin Acquisition, we now have full ownership of intellectual property rights to PH94B and PH10. In addition, we also have three new early clinical-stage pherine product candidates: PH15, a potential treatment for cognition improvement; PH80, a potential treatment for migraine and hot flashes; and PH284, a potential treatment for appetite-related disorders.

As consideration for the Pherin Acquisition, we (i) issued an aggregate of 12,410,100 unregistered shares of our common stock to the exchange agent for the Pherin Acquisition, of which 12,193,069 Shares were issued to the Selling Stockholders, consisting of approximately 96.07% of Pherin stockholders eligible to receive common stock in exchange for their outstanding shares of Pherin common stock (the Stock Consideration), and (ii) paid to the exchange agent for the Pherin Acquisition, an aggregate of approximately $126,100 to be paid to the approximately 3.93% remaining Pherin stockholders who were not eligible to receive Stock Consideration in exchange for their outstanding shares of Pherin common stock (the Cash Consideration).

On the Closing Date, we entered into a registration rights agreement (the Registration Rights Agreement) with the Stockholder Representative pursuant to which, among other matters, the Selling Stockholders were granted certain mandatory, demand and “piggy-back” registration rights with respect to the Shares received as preferredconsideration for the Pherin Acquisition. In addition, non-independent directors of Pherin and holders of 10% or more of the issued and outstanding shares of Pherin common stock thatprior to the Effective Time delivered to the Company executed lock-up agreements which prohibit the sale or other disposition of their respective Shares for a period of 180 days.

Pursuant to this prospectus, we mayare registering, on behalf of the Selling Stockholders, the shares of common stock issued as Stock Consideration.

Additional information about the Pherin Acquisition and the Merger Agreement are contained in the Company’s Current Reports on Form 8-K filed with the SEC on December 21, 2022 and on February 2, 2023.

Exercise of Warrants
Each holder of a warrant will be entitled to purchase the number of shares of common stock or preferred stock, as the case may be, at the exercise price described in the applicable prospectus supplement or free writing prospectus. After the close of business on the day when the right to exercise terminates (or a later date if we extend the time for exercise), unexercised warrants will become void.
A holder of warrants may exercise them by following the general procedure outlined below:
delivering to the warrant agent the payment required by the applicable prospectus supplement or free writing prospectus to purchase the underlying security;
properly completing and signing the reverse side of the warrant certificate representing the warrants; and
delivering the warrant certificate representing the warrants to the warrant agent within five business days of the warrant agent receiving payment of the exercise price.
If a holder complies with the procedures described above, such warrants will be considered to have been exercised when the warrant agent receives payment of the exercise price, subject to the transfer books for the securities issuable upon exercise of the warrant not being closed on such date. After the holder has completed those procedures and subject to the foregoing, we will, as soon as practicable, issue and deliver to such holder the common stock or preferred stock purchased upon exercise. If the holder exercises fewer than all of the warrants represented by a warrant certificate, a new warrant certificate will be issued to the holder for the unexercised amount of warrants. Holders of warrants will be required to pay any tax or governmental charge that may be imposed in connection with transferring the underlying securities in connection with the exercise of the warrants.
Amendments and Supplements to the Warrant Agreements
We may amend or supplement a warrant agreement without the consent of the holders of the applicable warrants to cure ambiguities in the warrant agreement, to cure or correct a defective provision in the warrant agreement, or to provide for other matters under the warrant agreement that we and the warrant agent deem necessary or desirable, so long as, in each case, such amendments or supplements do not materially adversely affect the interests of the holders of the warrants.
Warrant Adjustments
Unless the applicable prospectus supplement or free writing prospectus states otherwise, the exercise price of, and the number of securities covered by, a common stock or a preferred stock warrant will be adjusted proportionately if we subdivide or combine our common stock or preferred stock, as applicable. In addition, unless the prospectus supplement or free writing prospectus states otherwise, if we, without receiving payment:
issue capital stock or other securities convertible into or exchangeable for common stock or preferred stock, or any rights to subscribe for, purchase or otherwise acquire any of the foregoing, as a dividend or distribution to holders of our common stock or preferred stock;
pay any cash to holders of our common stock or preferred stock other than a cash dividend paid out of our current or retained earnings or other than in accordance with the terms of the preferred stock;
issue any evidence of our indebtedness or rights to subscribe for or purchase our indebtedness to holders of our common stock or preferred stock; or
issue common stock or preferred stock or additional stock or other securities or property to holders of our common stock or preferred stock by way of spinoff, split-up, reclassification, combination of shares or similar corporate rearrangement,
-19-
then the holders of common stock or preferred stock warrants will be entitled to receive upon exercise of the warrants, in addition to the securities otherwise receivable upon exercise of the warrants and without paying any additional consideration, the amount of stock and other securities and property such holders would have been entitled to receive had they held the common stock or preferred stock, as applicable, issuable under the warrants on the dates on which holders of those securities received or became entitled to receive such additional stock and other securities and property.
Except as stated above or as otherwise set forth in the applicable prospectus supplement or free writing prospectus, the exercise price and number of securities covered by a common stock or preferred stock warrant, and the amounts of other securities or property to be received, if any, upon exercise of such warrant, will not be adjusted or provided for if we issue those securities or any securities convertible into or exchangeable for those securities, or securities carrying the right to purchase those securities or securities convertible into or exchangeable for those securities.
Holders of common stock and preferred stock warrants may have additional rights under the following circumstances:
certain reclassifications, capital reorganizations or changes of the common stock or preferred stock, as applicable;
certain share exchanges, mergers, or similar transactions involving us and which result in changes of the common stock or preferred stock, as applicable; or
certain sales or dispositions to another entity of all or substantially all of our property and assets.
If one of the above transactions occurs and holders of our common stock or preferred stock are entitled to receive stock, securities or other property with respect to or in exchange for their securities, the holders of the common stock warrants and preferred stock warrants then outstanding, as applicable, will be entitled to receive, upon exercise of their warrants, the kind and amount of shares of stock and other securities or property that they would have received upon the applicable transaction if they had exercised their warrants immediately before the transaction.
Series A1 Warrants
As described above, we have issued Series A1 Warrants to purchase up to 1,388,931 shares of our common stock at an exercise price of $1.82 per share, which warrants expire on or about March 7, 2023. The Series A1 Warrants Shares that may become issuable from time to time upon the exercise of the Series A1 Warrants are being offered pursuant to this prospectus. For more information, see “Registration of Series A1 Warrants and Series A1 Warrant Shares” below.
Duration and Exercise Price: The Series A1 Warrants are exercisable for a five-year period commencing on or about March 7, 2018, and have an exercise price of $1.82 per share.
Exercisability: Each of Series A1 Warrant may be exercised, in whole or in part, by delivering to the Company a written notice of election to exercise the applicable Series A1 Warrant and delivering to the Company cash payment of the exercise price, if applicable. The exercise price and the number of shares of our common stock issuable upon exercise of the Series A1 Warrants is subject to adjustment in the event of certain subdivisions and combinations, including by any stock split or reverse stock split, stock dividend, recapitalization or otherwise.
Cashless Exercise: If, at any time during the term of the Series A1 Warrants, the issuance or resale of shares of our common stock upon exercise of the Series A1 Warrants is not covered by an effective registration statement, the holder is permitted to effect a cashless exercise of the Series A1 Warrants (in whole or in part) in which case the holder would receive upon such exercise the net number of shares of common stock determined according to the formula set forth in the Series A1 Warrants. Shares issued pursuant to a cashless exercise would be deemed to have been issued pursuant to the exemption from registration provided by Section 3(a)(9) of the Securities Act, and the shares of common stock issued upon such cashless exercise would take on the characteristics of the Series A1 Warrants being exercised, including, for purposes of Rule 144(d) promulgated under the Securities Act, a holding period beginning from the original issuance date of the Series A1 Warrants.
Adjustment Provisions: The exercise price and the number and type of securities purchasable upon exercise of the Series A1 Warrants are subject to adjustment upon certain corporate events, including certain subdivisions, combinations and similar events  If we declare any dividend or distribution of assets (including cash, stock or other securities, evidence of indebtedness, purchase rights or other property), each holder of a Series A1 Warrant will be entitled to participate in such distribution to the same extent that the holder would have participated had the applicable Series A1 Warrant been exercised immediately before the record date for the distribution. 
-20-
Transferability: Subject to applicable laws, the Series A1 Warrants may be offered for sale, sold, transferred or assigned without our consent. However, as of the date of this prospectus there is no established trading market for the Series A1 Warrants and it is not expected that a trading market for the Series A1 Warrants will develop in the future. Without an active trading market, the liquidity of the Series A1 Warrants will be limited.
Listing: We have not and will not apply to list the Series A1 Warrants on Nasdaq Capital Market. We do not intend to list the Series A1 Warrants on any securities exchange or other quotation system. Without an active market, the liquidity of the Series A1 Warrants will be limited.
Rights as a stockholder: Except as set forth in the Series A1 Warrants or by virtue of such holders’ ownership of shares of our common stock, the holders of the Series A1 Warrants do not have the rights or privileges of holders of our common stock, including any voting rights, until they exercise the Series A1 Warrants.
Limitations on Exercise: The exercise of the Series A1 Warrants may be limited in certain circumstances if, after giving effect to such exercise, the holder or any of its affiliates would beneficially own (as determined in accordance with the terms of the Series A1 Warrants) more than 4.99% (or, at the election of the holder, 9.99%) of our outstanding common stock immediately after giving effect to the exercise.
Fundamental Transactions: In the event of certain fundamental transactions, as described in the Series A1 Warrants and generally including any merger or consolidation with or into another entity, the holders of the Series A1 Warrants shall thereafter have the right to exercise the applicable Series A1 Warrant for the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence of such fundamental transaction if it had been, immediately prior to such fundamental transaction, the holder of shares of common stock issuable upon exercise in full of the Series A1 Warrant. In the event of a Change of Control (as defined in the Series A1 Warrants) (other than a Change of Control which was not approved by our Board, as to which this right shall not apply), at the request of the holder delivered before the 30th day after such Change of Control, a holder of a Series A1 Warrant will have the right to require us or any successor entity to purchase the holder’s Series A1 Warrant for the Black-Scholes Value of the remaining unexercised portion of the Series A1 Warrant on the effective date of such Change of Control (determined in accordance with a formula specified in the Series A1 Warrants), payable in cash; provided, that if the applicable Change of Control was not approved by our Board, such amount shall be payable, at our option in either (x) shares of our common stock or the consideration receivable by holders of common stock in the Change of Control transaction, as applicable, valued at the value of the consideration received by the shareholders in such Change of Control, or (y) cash.
Dividends and Other Distributions: If we declare or make any dividend or other distribution of our assets to holders of shares of our common stock (including any distribution of cash, stock or other securities, property, options, evidence of indebtedness or any other assets), then, subject to certain limitation on exercise described in the Series A1 Warrants, each holder of a Series A1 Warrant shall receive the distributed assets that such holder would have been entitled to receive in the distribution had the holder exercised the Series A1 Warrant immediately prior to the record date for the distribution.
Registration of Series A1 Warrants and Series A1 Warrant Shares. The Series A1 Warrants and the Series A1 Warrant Shares were previously registered pursuant to a prospectus supplement filed with the SEC on August 31, 2017 pursuant to Rule 424(b)(5) under the Securities Act, and pursuant to theCompany’s effective shelf registration statements on Form S-3 (File Nos. 333-215671 and 333-234025) (the Prior Registration Statements), which were originally filed with the Securities and Exchange Commission (the SEC) on January 23, 2017 and September 30, 2019, respectively, and declared effective by the SEC on July 27, 2017 and October 8, 2019, respectively.

Anti-Takeover Provisions
Our Charter and Nevada law include certain provisions which may have the effect of delaying or deterring a change in control or in our management or encouraging persons considering unsolicited tender offers or other unilateral takeover proposals to negotiate with our board of directors rather than pursue non-negotiated takeover attempts. These provisions include authorized blank check preferred stock, restrictions on business combinations, and the availability of authorized but unissued common stock.
-23-
Combination with Interested Stockholders Statute
Sections 78.411 to 78.444 of the NRS, which apply to any Nevada corporation which has at least 200 stockholders of record and is publicly traded, including us, prohibits an “interested stockholder” from entering into specified types of business “combinations” with the Nevada corporation for two years, unless certain conditions are met. A “combination” includes:
any merger of the corporation or any subsidiary of the corporation with an “interested stockholder,” or any other entity, whether or not itself an “interested stockholder,” which is, or after and as a result of the merger would be, an affiliate or associate of an “interested stockholder;”
any sale, lease, exchange, mortgage, pledge, transfer, or other disposition in one transaction, or a series of transactions, to or with an “interested stockholder” or any affiliate or associate of an “interested stockholder,” of assets of the corporation or any subsidiary:
i.
having an aggregate market value equal to more than 5% of the aggregate market value of the corporation’s assets, determined on a consolidated basis;
ii.
having an aggregate market value equal to more than 5% of the aggregate market value of all outstanding voting shares of the corporation; or
iii.
representing more than 10% of the earning power or net income, determined on a consolidated basis, of the corporation; or
the issuance or transfer by the corporation or any subsidiary, of any shares of the corporation or any subsidiary to an “interested stockholder” or any affiliate or associate of an “interested stockholder,” having an aggregate market value equal to 5% or more of the aggregate market value of all of the outstanding voting shares of the corporation, except under the exercise of warrants or rights to purchase shares offered, or a dividend or distribution paid or made, pro rata to all stockholders of the resident domestic corporation;
the adoption of any plan, or proposal for the liquidation or dissolution of the corporation, under any agreement, arrangement or understanding, with the “interested stockholder,” or any affiliate or associate of the “interested stockholder;”
if any of the following actions occurs
i.
a reclassification of the corporation’s securities,Registration Rights Agreement, including, without limitation, any splitting of shares, share dividend, or other distribution of shares with respect to other shares, or any issuance of new shares in exchange for a proportionately greater number of old shares;
ii.
recapitalization of the corporation;
iii.
merger or consolidation of the corporation with any subsidiary; or
iv.
any other transaction, whether or not with or into or otherwise involving the interested stockholder,
under any agreement, arrangement or understanding, whether or not in writing, with the interested stockholder or any affiliate or associate of the interested stockholder, which has the immediateSEC filing fees and proximate effect of increasing the proportionate share of the outstanding shares of any class or series of voting shares or securities convertible into voting shares of the corporation or any subsidiary of the corporation which is beneficially owned by the interested stockholder or any affiliate or associate of the interested stockholder, except as a result of immaterial changes because of adjustments of fractional shares; or
any receipt by an “interested stockholder” or any affiliate or associate of an “interested stockholder,” except proportionately as a stockholder of the corporation, of the benefit of any loan, advance, guarantee, pledge or other financial assistance or any tax credit or other tax advantage provided by or through the corporation.
An “interested stockholder” is a person who is:
directly or indirectly, the beneficial owner of 10% or more of the voting power of the outstanding voting shares of the corporation; or
an affiliate or associate of the corporation, which at any time within two years immediately before the date in question was the beneficial owner, directly or indirectly, of 10% or more of the voting power of the then outstanding shares of the corporation.
-24-
A corporation to which the Combinations with Interested Stockholders Statute applies may not engage in a “combination” within two years after the interested stockholder first became an interested stockholder, unless the combination meets all of the requirements of the corporation’s articles of incorporation and (i) the combination or the transaction by which the person first became an interested stockholder is approved by the board of directors before the person first became an interested stockholder, or (ii)(a) the combination is approved by the board of directors and (b) at or after that time, the combination is approved at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of the stockholders representing at least 60% of the outstanding voting power of the corporation not beneficially owned by the interested stockholder or the affiliates or associates of the interested stockholder. If this approval is not obtained, the combination may be consummated after the two year period expires if either (i)(a) the combination or transaction by which the person first became an interested stockholder is approved by the board of directors before such person first became an interested stockholder, (b) the combination is approved by a majority of the outstanding voting power of the corporation not beneficially owned by the interested stockholder or any affiliate or associate of the interested stockholder, or (c) the combination otherwise meets the requirements of the Combination with Interested Stockholders statute. Alternatively, a combination with an interested stockholder engaged in more than 2 years after the date the person first became an interested stockholder may be permissible if the aggregate amount of cash and the market value of consideration other than cash to be received by holders of shares of common stock and holders of any other class or series of shares meets the minimum requirements set forth in the statue, and prior to the completion of the combination, except in limited circumstances, the interested stockholder has not become the beneficial owner of additional voting shares of the corporation.
Acquisition of Controlling Interest Statute
In addition, Nevada’s “Acquisition of Controlling Interest Statute,” prohibits an acquiror, under certain circumstances, from voting shares of a target corporation’s stock after crossing certain threshold ownership percentages, unless the acquiror obtains the approval of the target corporation’s stockholders. Sections 78.378 to 78.3793 of the NRS only apply to Nevada corporations with at least 200 stockholders, including at least 100 record stockholders who are Nevada residents, that do business directly or indirectly in Nevada and whose articles of incorporation or bylaws in effect ten days following the acquisition of a controlling interest by an acquiror do not prohibit its application.
We do not intend to “do business” in Nevada within the meaning of the Acquisition of Controlling Interest Statute. Further, our Bylaws contain a specific opt out from the statute. Therefore, we believe it is unlikely that this statute will apply to us. The statute specifies three thresholds:
at least one-fifth but less than one-third;
at least one-third but less than a majority; and
a majority or more, of the outstanding voting power.
Once an acquiror crosses one of these thresholds, shares which it acquired in the transaction taking it over the threshold (or within 90 days preceding the date thereof) become “control shares” which could be deprived of the right to vote until a majority of the disinterested stockholders restore that right. A special stockholders’ meeting may be called at the request of the acquiror to consider the voting rights of the acquiror’s shares. If the acquiror requests a special meeting and gives an undertaking to pay the expenses of said meeting, then the meeting must take place no earlier than 30 days (unless the acquiror requestscompliance with state securities or “blue sky” laws; provided, however, that the meeting be held sooner) and no more than 50 days (unless the acquiror agrees to a later date) after the delivery by the acquiror to the corporation of an information statement which sets forth the range of voting power that the acquiror has acquired or proposes to acquire and certain other information concerning the acquiror and the proposed control share acquisition.
If no such request for a stockholders’ meeting is made, consideration of the voting rights of the acquiror’s shares must be taken at the next special or annual stockholders’ meeting. If the stockholders fail to restore voting rights to the acquiror, or if the acquiror fails to timely deliver an information statement to the corporation, then the corporation may, if so provided in its articles of incorporation or bylaws, call certain of the acquiror’s shares for redemption at the average price paid for the control shares by the acquiror.
Our Charter and our Bylaws, as do not currently permit us to redeem an acquiror’s shares under these circumstances. The Acquisition of Controlling Interest Statute also provides that in the event the stockholders restore full voting rights to a holder of control shares that owns a majority of the voting stock, thenSelling Stockholder will pay all other stockholders who do not vote in favor of restoring voting rights to the control shares may demand payment for the “fair value” of their shares as determined by a court in dissenter’s rights proceeding pursuant to Chapter 92A of the NRS.

LEGAL MATTERS

The validity of the securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.

Any underwriters who are qualified market makers on the Nasdaq Capital Market may engage in passive market making transactions in accordance with Rule 103 of Regulation M during the business day prior to the pricing of the offering, before the commencement of offers or sales of the securities. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain purchase limits are exceeded.

ITEM 15.  INDEMNIFICATION OF OFFICERS AND DIRECTORS
Officers.

Section 78.7502 of the NRS permits a corporation to indemnify any person who was, is or is threatened to be made a party in a completed, pending or threatened proceeding, whether civil, criminal, administrative or investigative (except an action by or in the right of the corporation), by reason of being or having been an officer, director, employee or agent of the corporation or serving in certain capacities at the request of the corporation. Indemnification may include attorneys' fees, judgments, fines and amounts paid in settlement. The person to be indemnified must have acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action, such person must have had no reasonable cause to believe his conduct was unlawful.

With respect to actions by or in the right of the corporation, indemnification may not be made for any claim, issue or matter as to which such a person has been finally adjudged by a court of competent jurisdiction to be liable to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court in which the action was brought or other court of competent jurisdiction determines upon application that in view of all circumstances the person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper.

Unless indemnification is ordered by a court, the determination to pay indemnification must be made by the stockholders, by a majority vote of a quorum of the Board of Directors who were not parties to the action, suit or proceeding, or in certain circumstances by independent legal counsel in a written opinion. Section 78.751 of the NRS permits the articles of incorporation or bylaws to provide for payment to an indemnified person of the expenses of defending an action as incurred upon receipt of an undertaking to repay the amount if it is ultimately determined by a court of competent jurisdiction that the person is not entitled to indemnification.

Section 78.7502 also provides that to the extent a director, officer, employee or agent has been successful on the merits or otherwise in the defense of any such action, he must be indemnified by the corporation against expenses, including attorneys' fees, actually and reasonably incurred in connection with the defense.

Article X of our Charter, entitled “Indemnification,” provides that we shall indemnify, and shall advance or reimburse the reasonable expenses incurred in advance of final disposition of the proceeding of, any individual made a party to a proceeding because that individual is or was a director of the corporation to the full extent and under all circumstances permitted by applicable law. Article X of our Bylaws, entitled “Indemnification,” provides that we shall indemnify our directors and officers to the fullest extent not prohibited by the NRS, except in the case of proceedings initiated by such officers or directors unless certain other factors are present.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and certain employees pursuant to the foregoing provisions, or otherwise, we have been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act, and is, therefore, unenforceable.

There is no pending litigation or proceeding naming any of our directors or officers as to which indemnification is being sought, nor are we aware of any pending or threatened litigation that may result in claims for indemnification.
