10 II. Ensysce Overview

ENSYSCE OVERVIEW Ensysce is a clinical - stage drug company using its proprietary prodrug technology platform to improve safety of prescription drugs. First focus is to develop an entirely new class of powerful, tamper - proof opioids that prevent both drug abuse and drug overdoses 11 • CLINICAL STAGE COMPANY: • Two new , revolutionary platforms that aim to eliminate opioid abuse (TAAP) and prevent drug overdose (MPAR) • Repurposed protease inhibitor program for a COVID - 19 Therapeutic and Cystic Fibrosis . • FDA FAST TRACK: lead drug product PF614 • NIH/NIDA govt awards: major funding through 2024 (1) • NEW CLASS OF PAIN DRUGS TO LAUNCH 2024 Note: 1) A portion of funding subject to reaching clinical development milestones.

Massive Opioid Crisis The deaths related to the misuse or abuse of opioids have exponentially increased over the past two decades, and drug manufacturers have not been able to develop a successful solution to this crisis 12 Source: FDA Analysis of Long - Term Trends in Prescription Opioid Analgesic Products: Quantity, Sales, and Price Trends March 2018

MPAR TM designed go prevent drug overdose by inhibiting the release of a drug when excessive amounts are taken ENSYSCE’S SOLUTIONS FOR ABUSE + OVERDOSE 13 MPAR TM Combining anti - abuse and anti - overdose technology to create new classes of prescription drugs that are powerful and safe for everyone INTEGRATED PRODRUG TECHNOLOGY PLATFORM 1. EFFECTIVE: TAAP TM relieves pain just as well as traditional opioids and has a longer pain relief time compared to traditional opioids 2. SAFE: TAAP TM side effects are limited to those of traditional opioids 3. PROTECTIVE: TAAP TM delivers pain relief without the ability to achieve instant euphoria 1. EFFECTIVE: MPAR TM prevents activation and full release of TAAP TM opioids if more than the prescribed does is consumed 2. SELECTIVE: MPAR TM is only triggered during an overdose TAAP TM designed to prevent drug abuse by using its innovative two step release TAAP TM ENSYSCE HAS CREATED TWO NEW DRUG PLATFORMS, TAAP ༩ AND MPAR ༩ , THAT ARE DESIGNED TO COMBAT ABUSE AND PREVENT OVERDOSE

LOW CNS PENETRATION thereby limiting the amount of drug in the brain to bind to receptors and preventing euphoric side effect Opioid Receptor Binding PF614 LOW AFFINITY: without GI activation, reducing the binding to receptors and hence, minimal side effect INACTIVE if inhaled or injected CANNOT BE MANIPULATED to provide active opioid immediately; must be swallowed and released in gastrointestinal tract, thereby preventing abuse 12 HOURS , truly twice a day CNS Penetration Inhalation / Injection Manipulation Half - Life VS 14 TAAP TM – modified oxycodone provides longer pain relief and a lower risk for abuse than the traditional oxycodone ENSYSCE SOLUTION VS. THE COMPETITION Oxycodone HIGH AFFINITY: increasing the strength of binding to receptors and hence, promoting pleasure (euphoria) HIGH CNS PENETRATION thereby increasing the amount of drug in the brain to bind to receptors and providing euphoria ACTIVE IMMEDIATELY if inhaled or injected CAN BE MANIPULATED by crushing to provide active opioid immediately and therefore, opioid abuse 5 - 7 HOURS , yet prescribed twice a day

COVISTAT INVESTMENT Opportunity • COVISTAT - utilizing Ensysce Bioscience’s knowledge of Nafamostat for a COVID - 19 drug therapy through a perpetual, royalty free license to oral nafamostat. • Drug repurposing business model potentially significantly lowers clinical development risk and increases return on investment. • Clinical Phase I with oral Nafamostat initiated/ Phase 2 scheduled to follow in US, Belgium, and Italy • Pipeline of products – oral and inhalation product to move beyond COVID - 19 for future coronavirus indications, orphan drug indications and pulmonary diseases. • Opportunity - pandemic therapeutic and prophylactic, breakthrough technology that has near term revenue potential and a strong competitive position in the Global COVID - 19 Market Category Details Industry Pharmaceuticals Markets Global Company Status Private Year Founded 2020 Product Oral & Inhaled Nafamostat Coronaviral infections/Cystic Fibrosis Business Model Drug Repurposing Model Current Testing Phase Phase I Covistat is undertaking clinical development of Nafamostat in the anti - viral and pulmonary markets Re - purposed NCE with low price of $1 - 2 per day

16 III. Key Investment Highlights

Key Investment Highlights Revolutionary Abuse - Resistant Opioids – Ensysce has developed a breakthrough technology to produce opioids in a manner that can provide effective pain - relief without allowing for abuse. C 17 Successful Phase I Data – Phase I data have demonstrated Ensysce’s opioid PF614 as abuse - resistant and safe without compromising on efficacy; PF614 expected to launch by 2024 generating revenue for ongoing programs. De - Risked and Accelerated FDA Milestones – Ensysce has secured FDA Fast - Track Designation and is using the 505(b)(2) regulatory pathway, substantially reducing the trial/regulatory risk and potential time to market. NIH/NIDA Grant of $23MM – Ensysce has been awarded a coveted $23MM non - dilutive grant in funding from National Institute on Drug Abuse (NIDA) and National Institute of Health (NIH) , helping accelerate the Company’s development pipeline and reducing equity required from investors. Breakthrough Technology Well - Protected by Patents – Ensysce has over 100 patents already issued in 25 countries, ensuring a barrier to entry from new competitors globally. Huge Unmet Need – Currently, there are virtually no opioids that can be prescribed without abuse and overdose potential. There are no low - cost therapeutic agents to treat COVID - 19. Well - Rounded Seasoned Management – Ensysce has an experienced leadership team with significant expertise and experience in all facets of biotech company - building, from drug development to commercialization . C C

HUGE UNMET NEED The chronic pain market with opioid indication has a huge unmet need with virtually no effective opioids that can be prescribed without abuse and overdose potential 18 Massive Market • Annual U.S. opioid is an attractive market of approximately $18.4 (1) Billion with opioid prescriptions constituting more than half of the total prescription pain market (2 ) 153 million opioid prescriptions every year. (3 ) Abuse - Deterrent Formulas are Ineffective • The current abuse - deterrent opioids have not been delivering true deterrence and combatting abuse since they are mere physical modulations and can be easily crushed and abused, signaling the huge unmet need for better alternatives. Opioid Restriction is Damaging • Denying people who rely on opioids to successfully manage chronic pain may cause them to regress into pain and unable to work . Frequently desperate to alleviate pain caused by serious medical conditions, chronic pain sufferers may turn to street drugs or even suicide. MORE PAIN MORE PAIN KILLERS MORE PAIN KILLERS THAT KILL

ENSYSCE’S REVOLUTIONARY ABUSE - RESISTANT OPIOIDS Ensysce has developed a breakthrough technology to make novel opioids that provide effective pain - relief without causing abuse and addiction 19 Ensysce’s breakthrough opioid is activated by enzyme Trypsin present only in gut • TAAP TM breakthrough technology is a chemical modulation of opioids. • It has a revolutionary 2 - step release process that achieves the intended goal of effective pain - relief while eliminating the potential for user abuse. • TAAP TM PF614 is chemically modified oxycodone – is inactive and can only be activated by the enzyme Trypsin only be found in a person’s gut. • TAAP effectively eliminates all forms of potential abuse , since the opioid is in an inactive state and cannot be activated through injection, inhalation or chewing.

SUCCESSFUL PRE - CLINICAL & PHASE I DATA Pre - clinical and phase I data has proven Ensysce’s opioid PF614 to be abuse - resistant and safe without compromising on efficacy, de - risking the further development 20 Time (hr) Oxycodone mean concentration (ng/mL) 0 2 4 6 8 10 12 0 50 100 150 200 UNTAMPERED OxyContin 20mg CRUSHED PF 614 CRUSHED Oxycodone 20mg • Unlike OxyContin , Ensysce’s opioid PF614, even when crushed, releases oxycodone only slowly in the blood, thereby preventing euphoria (pleasure) and abuse • In pre - clinical studies, the PF614 achieved similar concentrations and duration of action in the blood as the current opioid, establishing similar efficacy in pain - relief as OxyContin • Phase I trial demonstrated that PF614 is safe to use in humans without causing any major side effects such as severe allergic reaction (anaphylaxis), seizures or heart attack Blood Concentration of Opioid Vs. Time Pre - clinical data in dogs comparing Ensysce’s opioid against current opioid OxyContin demonstrated that Ensysce can prevent opioid abuse while OxyContin cannot

DE - RISKED AND ACCELERATED FDA MILESTONES Ensysce has secured FDA Fast - Track Designation and is using the 505(b)(2) regulatory pathway, substantially reducing the trial/regulatory risk and time to market 21 • 505(b)(2) regulatory pathway status from the FDA and successful Phase I data de - risk the regulatory path , since Ensysce can submit bioequivalence data demonstrating the efficacy of the already - proven reference drug oxycodone on the market, drastically increasing the probability of success and reducing costs for Phase 3 trials • Ensysce’s PF 614 has secured Fast Track designation from the FDA, enabling ongoing communication and collaboration with the FDA in all stages of drug - development with eligibility for accelerated approval , significantly reducing the costs and time to market in 2023 • Ensysce has completed a preliminary study with the leading abuse - testing lab in the U.S. This study showed that PF614 could not be “cracked” by kitchen chemistry, a unique finding which no ADF has been able to achieve • Additionally, Human Abuse Liability (HAL) and Kitchen Chemistry Test designed with FDA’s guidance would enable Ensysce to get Abuse Deterrent Labelling and differentiate Ensysce’s opioid PF614 from OxyContin

COVETED, NON - DILUTIVE NIH/NIDA GRANT OF $23MM Ensysce has been awarded coveted $23MM non - dilutive funding by NIH/NIDA, providing recognition to Ensysce’s technologies in combating abuse and reducing equity risk for investors (1) 22 • The NIH/NIDA funding is a testament of credibility and recognition by NIDA, NIH and the federal government of the value of Ensysce’s technologies (TAAP TM and MPAR TM ) in preventing opioid abuse and overdose. • In 2018, Ensysce received $9MM of NIDA grant for pre - clinical and Phase I development of MPAR TM technology to prevent opioid overdose • In Dec. 2019, Ensysce was awarded an additional $14.5MM under the NIH’s HEAL Initiative for pre - clinical and Phase I development of Opioid Use Disorder treatment (TAAP TM Methadone) using Ensysce’s TAAP TM and MPAR TM overdose protection platforms. • NIH/NIDA grants provide non - dilutive sources of capital for development of the assets in the pipeline, potentially reducing equity risk and increasing the upside on invested capital for equity investors. Note: 1) A portion of funding is predicated on Ensysce achieving agreed upon clinical development milestones.

Ensysce has over 100 patents already issued in 25 countries, ensuring barriers to entry for new companies globally 23 • Ensysce’s technology is well - protected by a suite of 111 patents i ssued in the U.S. and overseas (the UK, a majority of the EU, Australia, China, and others with a total of 25 countries), ensuring a barrier to entry for other companies in these markets. • These patents provide protection to the underlying molecules of both the immediate and extended release formulations of Ensysce. • Ensysce patent pipeline will grow with a number of new products in development, has a library of trade secrets and trademarks. Color coded regions on the map indicate countries where patents have been issued EXTENSIVE PATENT PORTFOLIO

Ensysce’s leadership has significant experience in all facets of biotech company - building, from drug development to commercialization 24 • Ensysce’s team is led by CEO Lynn Kirkpatrick, who is a serial biotech entrepreneur with over 100 publications in peer - reviewed journals and a featured biotech superstar. • Ensysce has assembled an extraordinary team with an extensive track record in leading teams and taking drugs through development, regulatory approvals, capital raise and commercialization in both public and private companies. • Ensysce has an outstanding advisory team which includes some of the leading opioid experts in the world with decades of experience in pain medication and opioid abuse.

29 V. Appendices

30 Ensysce Product Pipeline

TAMPER - PROOF ANTI - ABUSE TM TAAP TM is only activated by trypsin , a digestive enzyme that exists only in the gut; therefore crushing, inhaling or injecting it will not cause the opioid to be released faster to produce pleasure/euphoria 31 TAAP TM chemically modifies the opioid, thereby eliminating the potential abuse by the patient through physical means (e.g., crushing and subsequent injection)

The picture can't be displayed. 32 TWO - STEP RELEASE PROCESS opioid + linker : amino acid opioid + linker + trypsin amino acid opioid cyclic urea chemically designed release timing T = 1 to 6 hours Fast = IR (immediate release) Slow = ER (extended release) Free and active drug absorbed into blood 1 2 ACTIVATION STEP 1 RELEASE STEP 2 exists in the gut only + time TAAP TM MECHANISM OF ACTION • The drug is activated by the enzyme trypsin only when it reaches the gut, preventing abuse outside the body • The inactive drug releases active oxycodone gradually in the blood, preventing immediate onset and abuse

SMART ANTI - OVERDOSE The prescribed activity of trypsin will not be affected by MPAR TM , therefore making it very safe for daily use TM MPAR TM inhibits trypsin when too much TAAP TM opioid is swallowed, inhibiting full activation and opioid release, and therefore, preventing overdose - related deaths 33 MPAR TM is only triggered by an overdose , blocking the additional doses consumed

MPAR TM Mechanism of Action DOSE - TRIGGERED TRYPSIN INHIBITION ABOVE THRESHOLD trypsin inhibitor ATTEMPTED / ACCIDENTAL OVERDOSE Free and active drug product Dose blocked / overdose averted 34 PRESCRIBED DOSE No Interference when normal dose of Ensysce’s opioid PF614 is taken; MPAR TM (trypsin inhibitor) does not affect the opioid TAAP TM – enabled opioid MPAR TM trypsin inhibitor Legend: When higher - than - normal dose of Ensysce’s opioid PF614 is taken to attempt to cause overdose, MPAR TM (trypsin inhibitor) inhibits the trypsin, thereby preventing activation of more Ensysce’s opioid PF614

ABUSE PREVENTION • As show in the graph on the left, the onset of Ensysce’s PF614 in blood is slow even at higher doses, demonstrating the ability to prevent opioid pleasure (euphoria) and abuse SAFE • PF614 has shown to be safe , and no unexpected adverse events were observed in Phase I EFFICIENT CONVERSION TO OXYCODONE • PF614 is effectively converted to Oxycodone with an efficiency of 90% , thereby replicating the pain - relief by OxyContin (oxycodone) 36 PF614: CLINICALLY PROVEN SAFER, EFFIECENT & LONGER - LASTING PAIN RELIEF TAAP TM : CLINICAL DATA Oxycodone concentration in Blood vs. Time SLOW ONSET max blood levels reached @ 4 – 6h across all cohorts 15 mg / 21 / no / fasted 15 mg / 22 / yes / fasted 25 mg / 6 / yes / fasted 50 mg / 6 / yes / fasted 100 mg / 6 / yes / fasted 200 mg / 6 / yes / fasted 200 mg / 8 / yes / high - fat Dose / n / Naltrexone / meal 0 6 12 18 24 30 36 0 20 40 60 80 100 Time (hr) Oxycodone mean concentration (ng/mL)

True Twice - a - Day Product • Ensysce’s opioid PF614’s half - life is 12.7 hours , versus OxyContin’s 7.6 hours • As a result, Ensysce’s PF614 is more convenient for the patient, since PF614 needs to be taken only twice - a - day , in contrast to OxyContin (which some patients end up taking three times per day ) 37 PF614 LONGER LASTING COMPARED TO OXYCONTIN TAAP TM : CLINICAL DATA Oxycodone half life The picture can't be display ed. 15 mg / 10 mg 25 mg / 10 mg 50 mg / 20 mg 100 mg / 50 mg 200 mg / 80 mg 200 mg / -- Dose (PF614 / OxyContin) 0 10 20 30 40 OxyContin Half Life = 7.6 hr PF614 Half Life = 12.7 hr

• Trypsin inhibition using nafamostat prevents opioid overdose by reducing PF614 activation with increasing dose unit administration • Data on the right demonstrate the effectiveness of Ensysce’s MPAR TM overdose protection, as oxycodone concentration does not rise in blood at high - doses due to MPAR TM - enabled trypsin inhibition 38 PF614 MPAR TM BLOCKS OXYCODONE RELEASE with overdose TAAP TM + MPAR TM : PRECLINICAL DATA WITH MPAR TM (PF614 with TI nafamostat) WITH OUT MPAR TM (PF614 with out TI nafamostat) Oxycodone mean concentration (ng/mL) Time (hr) 0 4 8 12 16 24 0 5 10 15 20 25 20 0 4 8 12 16 24 0 5 10 15 20 25 Time (hr) Oxycodone mean concentration (ng/mL) 20 10 dose units 6 dose units 3 dose units 1 dose units in rats n=4 / dose
