Background

PART I

TFF  Pharmaceuticals,  Inc.  was  formed  as  a  Delaware  corporation  on  January  24,  2018  for  the  purpose  of  developing  and  commercializing
innovative drug products based on our patented Thin Film Freezing, or TFF, technology platform. We were formed by Lung Therapeutics, Inc., or LTI, an
early stage biotechnology company focused on the development of certain technologies in the pulmonary field. In March 2018, we completed a Series A
preferred stock financing with third-party investors, at which time we acquired certain of LTI’s non-core intellectual property rights and other assets, all of
which relate to our TFF technology, for 4,000,000 shares of our common stock. As of the date of this report, LTI owns 4,000,000 shares of our common
stock, or approximately 21% of our capital stock. We are no longer a subsidiary of LTI.

Since  our  formation,  we  have  focused  on  the  development  of  our  initial  drug  candidates,  the  establishment  of  strategic  relationships  with
established  pharmaceutical  companies  for  the  licensing  of  our  TFF  technology  platform  and  the  pursuit  of  additional  working  capital.  We  have  not
commenced revenue-producing operations. Unless otherwise indicated, the terms “TFF Pharmaceuticals,” “Company,” “we,” “us,” and “our” refer to TFF
Pharmaceuticals, Inc. and its wholly-owned subsidiaries.

Since  our  organization  in  2018,  we  have  engaged  in  several  capital  raising  transactions,  which  are  summarized  below  in  “Management’s

Discussion and Analysis of Financial Condition and Results of Operations – General.”

Overview

We are an early-stage biopharmaceutical company focused on developing and commercializing innovative drug products based on our patented
Thin Film Freezing, or TFF technology platform. We believe, and early testing confirms, that our TFF platform can significantly improve the solubility of
poorly  water-soluble  drugs,  a  class  of  drugs  that  makes  up  approximately  33%  of  the  major  pharmaceuticals  worldwide,  thereby  improving  the
pharmacokinetic  effect  of  those  drugs.  We  believe  that  in  the  case  of  some  new  drugs  that  cannot  be  developed  due  to  poor  water-solubility,  our  TFF
platform has the potential to increase the pharmacokinetic effect of the drug to a level allowing for its development and commercialization. In November
2019,  we  initiated  Phase  I  human  clinical  trials  of  our  lead  product,  TFF  Vori,  however,  as  of  the  date  of  this  report,  we  have  not  progressed  the
development of any other of our drug candidates to human clinical trials and our efforts have focused on the formulation, early stage animal testing and
formal toxicology studies of our initial drug candidates in preparation for our first clinical trials.

We intend to initially focus on the development of inhaled dry powder drugs for the treatment of pulmonary diseases and conditions. While the
TFF platform was designed to improve solubility of poorly water-soluble drugs generally, the researchers at University of Texas at Austin, or UT, found
that the technology was particularly useful in generating dry powder particles with properties which allow for superior inhalation delivery, especially to the
deep  lung,  which  is  an  area  of  extreme  interest  in  respiratory  medicine.  We  believe  that  our  TFF  platform  can  significantly  increase  the  number  of
pulmonary drug products that can be delivered by way of breath-actuated inhalers, which are generally considered to be the most effective and patient-
friendly means of delivering medication directly to the lungs. Our dry powder drug products will be designed for use with dry powder inhalers, which are
generally considered to be the most effective of all breath-actuated inhalers. We plan to focus on developing inhaled dry powder formulations of existing
off-patent drugs intended for lung diseases and conditions, which we believe includes dozens of potential drug candidates, many of which have a potential
market ranging from $100 million to over $500 million.

We also focused on the joint development of dry powder formulations of proprietary drugs owned or licensed by other pharmaceutical companies.
As  of  the  date  of  this  report,  we  are  at  various  stages  of  three  different  feasibility  studies  of  new  chemical  entities  owned  by  three  international
pharmaceutical companies. In addition, we recently commenced preliminary analysis and testing of dry powder formulations of certain drugs and vaccines
through topical, ocular and nasal applications in connection with our participation in submissions made to certain government agencies for government
contracts.

Our  business  model  is  to  develop  proprietary  innovative  drug  product  candidates  that  offer  commercial  or  functional  advantages,  or  both,  to
currently available alternatives. Because our initial dry powder drug candidates, TFF Vori and TFF Tac-Lac, will be established drugs that are off-patent,
we believe that our initial drug product candidates will qualify for approval by the U.S. Food and Drug Administration, or FDA, through the FDA’s 505(b)
(2)  regulatory  pathway  and  in  corresponding  regulatory  paths  in  other  foreign  jurisdictions. The  505(b)(2)  pathway  sometimes  does  not  require  clinical
trials  other  than  a  bioequivalence  trial.  However,  to  the  extent  we  claim  that  our  product  candidates  target  a  new  indication  or  offer  improved  safety
compared to the existing approved products, and it is our present expectation that we will in many cases, it is likely that we will be required to conduct
additional  clinical  trials  in  order  to  obtain  marketing  approval.  For  example,  and  as  more  fully  described  below,  based  on  a  February  2019  pre-
Investigational  New  Drug  Application,  or  IND,  meeting  with  the  FDA  concerning  TFF  Vori,  we  believe  we  will  need  to  conduct  Phase  I  and  Phase  II
studies prior to filing for marketing approval for TFF Vori. In addition, based on a September 2019 pre-IND meeting with the FDA concerning TFF Tac-
Lac, we also believe we will require Phase I and Phase IIb/IIIa studies prior to filing for marketing approval for TFF Tac-Lac. However, there can be no
assurance that the FDA will not ask for additional clinical data for either TFF Vori or TFF Tac-Lac.

While we intend to target the development of off-patent drugs for which we would directly pursue the development of a dry powder formulation
through the FDA’s 505(b)(2) regulatory pathway, not all of our product candidates will target off-patent drugs and, at least in the case of a dry powder
formulation  of  cannabidiol,  or  CBD,  our  product  candidate  may  not  be  a  drug.  We  do  not  expect  our  proposed  dry  powder  formulation  of  CBD  drug
product to be off-patent and our proposed dry powder formulation of aluminum salt vaccines may not be off-patent. We also expect that our dry powder
formulation of CBD drug product will likely require a full New Drug Application, or NDA, through the FDA’s 505(b)(1) regulatory pathway; however, a
non-pharmaceutical CBD dry powder formulation, such as a dietary supplement, may not require FDA pre-market approval. We expect that our dry powder
formulation of aluminum salt vaccines will require a biological license application, or BLA, which is very similar to a full NDA through the FDA’s 505(b)
(1) regulatory pathway.

We also believe that in some cases our dry powder drug products may qualify for the FDA’s orphan drug status. Upon and subject to receipt of the
requisite approvals, we intend to commercialize our drug product candidates through a combination of our internal direct sales and third-party marketing
and distribution partnerships. In some cases, such as the development of combination drugs or the development of dry powder formulations of patented
drugs, we intend to pursue the licensing of our TFF platform or a joint development arrangement.

Our Intended Regulatory Pathway

The  505(b)(2)  pathway  is  intended  for  molecules  that  have  been  previously  approved  by  the  FDA  or  have  already  been  proven  to  be  safe  and
effective. A 505(b)(2) product reformulates the known molecule in a new strength or dosage form. 505(b)(2) products have the advantage of potentially
significantly  lower  development  costs  and  shorter  development  timelines  versus  traditional  new  molecular  entities.  We  expect  to  utilize  the  505(b)(2)
pathway for all of our current product candidates.

A  505(b)(2)  NDA  is  an  application  that  contains  full  reports  of  investigations  of  safety  and  effectiveness,  but  where  at  least  some  of  the
information required for approval comes from studies not conducted by or for the applicant. This alternate regulatory pathway enables the applicant to rely,
in  part,  on  the  FDA’s  findings  of  safety  and  efficacy  for  an  existing  product,  or  published  literature,  in  support  of  its  application.  A  505(b)(2)  product
candidate  might  rely  on  the  clinical  studies  or  literature  of  a  previously  FDA-approved  drug,  or  rely  on  the  literature  and  physician  usage  of  an  FDA-
unapproved, or DESI, drug. The clinical requirements for a 505(b)(2) drug candidate can vary widely from product to product and may include new clinical
trials,  bioequivalence  trials,  limited  safety  and  efficacy  trials,  or  full  Phase  I  through  III  trials.  Unless  the  FDA  has  released  a  guidance  document,  the
clinical requirement for a new product candidate is typically not known until the drug sponsor has a Pre-IND meeting with the FDA. We believe there is a
significant opportunity to pursue dry powder formulations of off-patent drugs using the 505(b)(2) regulatory pathway.

2

 
 
 
 
 
 
 
 
We also believe that in some cases the indication for some of our dry powder drug product candidates may qualify for the FDA’s orphan drug
status. Under the Orphan Drug Act, the FDA may grant orphan designation to a drug intended to treat a rare disease or condition generally affecting fewer
than 200,000 individuals in the United States, or in other limited cases. Orphan drug designation provides for seven years of exclusivity, independent of
patent protection, to the company that brings a particular orphan drug to market. In addition, companies developing orphan drugs are eligible for certain
incentives, including tax credits for qualified clinical testing. In addition, an NDA for a product that has received orphan drug designation is not subject to a
prescription drug user fee unless the application includes an indication other than the rare disease or condition for which the drug was designated.

The Problem We Address

Solubility is an issue that all drugs must address. No matter how active or potentially active a new drug is against a particular molecular target, if
the drug is not available in solution at the site of action, it is most likely not a viable development candidate. Based on independent third-party studies, 40%
of newly discovered drugs have little or no water solubility, and in some therapeutic areas this number can reach 90%, which in most cases will prohibit
development since most pharmaceutical companies cannot or will not conduct rigorous preclinical and clinical studies on a molecule that does not have a
sufficient pharmacokinetic profile due to poor water solubility. Water solubility can also be an issue for some marketed drugs. Based on independent third-
party studies, only two-thirds of the drugs on the World Health Organization, or WHO, Essential Drug List were classified as high solubility. A marketed
drug with poor water solubility can show performance limitations, such as incomplete or erratic absorption, poor bioavailability, and slow onset of action.
Effectiveness can vary from patient to patient, and there can be a strong effect of food on drug absorption. Finally, it may be necessary to increase the dose
of a poorly soluble drug to obtain the efficacy required, which can lead to adverse side effects, toxicity issues and increased costs.

In addition to water solubility issues generally, certain drugs that target lung conditions and diseases have poor solubility that prevent them from
being delivered by way of a breath-actuated inhaler and can only be given orally or intravenously. Breath actuated inhalers include dry powder inhalers,
metered dose inhalers and nebulizers. A dry powder inhaler (such as the Advair Diskus) delivers drugs in a dry powder form directly to the lungs by way of
a deep, fast breath on the mouth of the inhaler. A metered dose inhaler (such as the Symbicort asthma inhaler) uses propellant to push medication to the
lungs.  A  nebulizer  (such  as  the  Aeroneb  Pro)  creates  a  mist  that  is  breathed  into  the  lungs  through  a  mouthpiece.  The  dry  powder  inhaler  is  generally
considered to be the most effective and convenient form of breath-actuated inhaler for all users, other than for those whose severe condition does not allow
them to take a sufficiently deep breath.

We believe the primary benefit of a breath-actuated inhaler is its ability to administer a greater portion of the drug dosage directly to the target site.
Dosing directly to the lungs has been shown to allow for better effect with fewer adverse events. In addition, it has been shown that dosing directly to the
lungs requires a much lower dose of drug, sometimes as little as 10%, compared to delivery by oral or parenteral routes. While breath-actuated inhalers
allow  for  a  greater  portion  of  the  administered  drug  to  reach  the  treatment  site,  which  should  allow  for  much  smaller  dosages  compared  to  oral  or
intravenous delivery, not all drugs targeting lung conditions and diseases can be formulated for use with a breath-actuated inhaler. We believe there are
dozens of off-patent drugs targeting lung conditions and diseases that are currently not eligible for delivery by way of breath-actuated inhalers, many of
which  have  a  potential  market  of  $100  million  to  over  $500  million.  This  is  the  market  we  intend  to  initially  address  through  our  development  of  dry
powder drugs utilizing our TFF platform.

Our Thin Film Freezing Platform

Our development of dry powder drugs is enabled by technology licensed to us by the University of Texas at Austin, or UT. Researchers at UT
have developed a technology employing a process called Thin Film Freezing, or TFF. While the TFF platform was designed to improve solubility of poorly
water-soluble drugs generally, the researchers at UT found that the technology was particularly useful in generating dry powder particles with properties
suitable for inhalation delivery, especially to the deep lung, an area of extreme interest in respiratory medicine. It was found that the TFF platform yields
particles that are particularly well suited to dry powder inhaler delivery. The process results in a “Brittle Matrix Particle,” which possess low bulk density,
high  surface  area,  and  typically  an  amorphous  morphology,  allowing  them  to  supersaturate  when  contacting  the  target  site,  such  as  lung  tissue.  The
aerodynamic properties of the particles are such that the portion of drug deposited to the deep lung may reach as high as 75% or greater of the administered
dose, compared to 10% or less when given orally or intravenously.

3

 
 
 
 
 
 
 
 
 
The TFF process, outlined in the figures below, involves dissolving a drug or drugs in a solvent system, and it will often include agents designed
to promote dispersion and avoid clumping and excipients to promote adhesion to the target site. The drug solution is then applied to a cryogenic substrate,
such as a liquid nitrogen cooled stainless steel drum. When the drug solution contacts the cryogenic surface it vitrifies, or flash freezes, resulting in a “drug
ice”  typically  with  amorphous  drug  morphology.  The  solvent  system  is  removed  by  lyophilization,  resulting  in  Brittle  Matrix  Particles,  shown  in  the
photographs below, that are highly porous, large surface area, low-density particles. The process uses industry standard solvents, lung-approved excipients,
a custom-made TFF drum and conventional process equipment.

We believe our TFF platform is a breakthrough platform technology for making dry powders from drugs which previously were not candidates for
the  dry  powder  inhaler  or  any  breath-actuated  inhaler.  We  believe  our  TFF  technology  opens  the  way  for  direct-to-lung  delivery  of  dozens  of
pharmaceuticals, including the reformulation of existing drugs into a more safe and convenient inhaled dry powder product. We believe the technology can
be used with molecules of all types and works with existing and off-the-shelf dry powder inhalers without the need for any additional equipment or devices.

We believe our TFF platform presents the following high value opportunities:

● Reformulation of drugs for lung conditions. Today, many drugs intended for lung conditions are only given orally or intravenously due to
properties that make them ill-suited for direct delivery by inhalers. Given by these routes, typically only 10% of the drug reaches the lungs,
and these drugs may cause unwanted and even deadly side effects. We believe that our TFF platform for the first time will allow many of
these  medications  to  be  formulated  into  the  convenient,  direct-to-lung  dry  powder  inhaler  format,  thereby  enhancing  efficacy,  reducing  or
eliminating side effects and providing for delivery of drug direct to the target site.

● Biologics.  Biopharmaceuticals  (or  biologics)  are  by  far  the  fastest  growing  sector  in  the  pharmaceutical  industry  today.  According  to
Visiongain, the market for biologics is expected to top $270 billion by 2019. Biologics are most commonly delivered intravenously, and they
can be an especially challenging class of drugs for formulation into a dry powder. We believe our TFF platform is uniquely suited to meet
many of the challenges of biologic formulations, and our UT collaborators have demonstrated, via animal model testing and in vitro testing,
the effectiveness of the TFF technology to produce dry powder biologics with up to 100% activity retained. We intend to explore dry powder
forms  of  numerous  biological  drugs,  including  drugs  intended  to  treat  indications  other  than  lung  conditions  and  diseases.  We  are  also
pursuing TFF formulations of salt containing vaccines, which we believe may provide significant advantages over the traditional method of
handling vaccines through liquid suspension and cold chain.

4

 
 
 
 
 
 
 
 
● Combination  Drugs.  Combination  drugs  are  products  with  two  or  more  active  pharmaceutical  ingredients.  In  addition  to  providing  for
increased  patient  compliance  with  multiple  medications,  some  drugs  act  synergistically  and  provide  for  superior  benefit  when  given  as  a
combination. However, combining pharmaceutical agents can be challenging, especially for inhalation delivery. Our TFF platform has shown
the ability to produce fixed dose combinations of many agents in a manner that delivers the drugs simultaneously to the site of action in a
precise amount.

UT initially licensed the TFF technology to The Dow Chemical Company, or Dow, and Dow researchers pursued the development of the TFF
platform  until  Dow’s  decision  to  divest  its  pharmaceutical  assets  in  2007.  While  at  Dow,  the  technology  was  scaled  from  laboratory  (milligrams)  to
pilot/commercial quantities (kilos). In addition, the Dow team showed that the scaling process did not alter the morphology or other properties of particles
made using TFF. More than a dozen drugs, including both small molecules and biologics, were processed by Dow researchers and UT collaborators using
the  technology,  and  the  benefits  were  quantified  using  both  in  vivo  and  analytical  techniques.  In  a  report  published  by  Dow  researchers  in  2008,  they
reported that in several drugs tested by them, there was evidence of enhanced dissolution rates using the TFF platform compared to bulk drugs. In one
instance, the researchers measured that a TFF prepared drug was able to reach 96% dissolution in two minutes compared to 60% dissolution in 30 minutes
by the same drug in bulk form.

Following its decision to divest its pharmaceutical assets in 2007, Dow’s license rights to the TFF platform were terminated. In July 2015, UT
granted to our former parent, LTI, an exclusive worldwide, royalty bearing license to the patent rights for the TFF platform in all fields of use, other than
vaccines, for which LTI was granted a non-exclusive worldwide, royalty bearing license to the patent rights for the TFF platform. In January 2018, we
entered into a Contribution and Subscription Agreement with LTI, pursuant to which we agreed to acquire from LTI certain intellectual property rights and
other assets, including the UT patent license agreement, all of which relate to our TFF platform. We closed on the acquisition of the LTI assets in March
2018. In November 2018, we and UT amended the UT patent license agreement pursuant to which, among other things, our exclusive patent rights to the
TFF platform were expanded to all fields of use.

We continue to work with the inventors of the TFF platform through a series of Sponsored Research Agreements, or SRAs, with UT. Our SRAs
with  UT  are  industry  standard  sponsored  research  agreements  pursuant  to  which  UT  provides  to  us  certain  product  formulation,  characterization  and
evaluation services with regard to our product candidates incorporating our TFF technology in exchange for our payment of UT’s expenses and reasonable
overhead.  The services conducted by UT are to be carried out under the direction of a principal investigator at UT who is the principal inventor of the TFF
technology.  The  current  SRA  expires  in  April  2022  and  is  subject  to  renewal  upon  mutual  agreement  of  the  parties.    The  SRAs  includes  customary
provisions  concerning  confidentiality,  indemnification  and  intellectual  property  rights,  including  each  party’s  exclusive  ownership  of  all  intellectual
property developed solely by them and the parties’ joint ownership of all intellectual property developed jointly.  All patented intellectual property rights
relating to the TFF technology developed solely or jointly by UT are subject to our patent license agreement with UT and are included among our licensed

We  have  entered  into  short-term  contract  manufacturing  agreements  with  IriSys,  Inc.  and  CoreRx,  Inc.  for  their  provision  of  certain  product
testing, development and clinical manufacturing services for our TFF Vori and TFF Tac-Lac product candidates, respectively. Our agreements with IriSys
and CoreRx include customary provisions concerning confidentiality, indemnification and intellectual property rights, including our exclusive ownership of
all  intellectual  property  developed  severally  or  jointly  relating  to  our  TFF  technology.  We  have  not  entered  into  agreements  with  any  contract
manufacturers for the commercial supply, however, we believe that both IriSys and CoreRx, among several other manufacturers, have the experience and
the capacity to serve as a commercial contract manufacturer. We believe we will be able to engage a commercial contract manufacturer for our product
candidates in a timely manner at competitive pricing.

Each of Patheon’s, CoreRx’s and IriSys’ facilities and services are conducted in accordance with the FDA’s current good manufacturing practices,
or cGMPs, regulations, and IriSys and CoreRx are in the process of onboarding the TFF technology to support preclinical and clinical supply of our TFF
Vori and TFF Tac-Lac drug product candidates, respectively.

Pursuant to the agreements with CoreRx and IriSys, they will generate clinical supplies and provide release and stability testing of the respective

TFF drug product candidate. Specific tasks will include:

● Engineering review and TFF technology installation;

● Familiarization with TFF technology, including powder processing and handling;

● Analytical method transfer, development, and validation;

● Conducting process development trials and short-term supportive stability analysis;

● Scale-up and demonstration batches of the product candidate;

● Manufacture and analytical characterization of materials to support toxicology studies, both, placebo and active;

● Process train qualification for cGMP manufacturing;

● Manufacturing and release of cGMP batches for clinical trials; and

● Conducting  formal  stability  study  under  the  guidelines  of  International  Council  for  Harmonisation  of  Technical  Requirements  for

Pharmaceuticals for Human Use, or ICH.

Because our dry powder drug candidates will represent a new formulation of an existing drug, we will need to obtain FDA approval of the TFF
prepared drug candidate before we can begin commercialization. However, because we begin our formulation with a drug that has previously received FDA
approval in another form, we believe that in most cases we should qualify for the FDA’s 505(b)(2) regulatory pathway, which potentially will take less time
and investment than the standard FDA approval process.

Our Initial Drug Targets

We  intend  to  initially  focus  on  the  development  of  inhaled  dry  powder  drugs  for  the  treatment  of  pulmonary  diseases  and  conditions.  Our  dry
powder drug product candidates will be designed for use with dry powder inhalers, which are generally considered to be the most effective of all breath-
actuated  inhalers.  We  intend  to  develop  dry  powder  drugs  that  can  be  used  with  existing  dry  powder  inhalers  that  are  commercially  available  without
licensing. We plan to focus on developing dry powder drugs intended for lung diseases and conditions that are off-patent, which we believe includes dozens
of potential drug candidates, many of which have a potential market ranging from $100 million to over $1 billion. As of the date of this report, we have
identified and are focusing on three initial drug candidates and with each we are in the early stages of formulation and testing.

TFF Vori - For the Treatment of Invasive Pulmonary Aspergillosis

We are developing an inhaled dry powder drug intended to treat invasive pulmonary aspergillosis, or IPA, a severe fungal pulmonary disease with
a  mortality  rate  that  can  reach  90%  in  some  patient  populations.  IPA  occurs  primarily  in  patients  with  severe  immunodeficiency,  such  as  bone  marrow
transplant recipients, other transplant patients, patients with chemotherapy-induced immunodeficiency, and HIV patients. To date, the antifungals used to
treat IPA have been delivered orally or intravenously. However, these delivery methods have resulted in low drug concentrations in the lung due to poor
bioavailability. We believe these antifungals have serious side effects and drug interaction issues, which places a premium on any solution that can provide
effective treatment in more limited dosages. Due to the nature of these drugs, it has not been possible to make formulations for breath-actuated inhalers that
might maximize lung concentration while limiting side effects.

We believe, and early in vitro and animal testing confirms, that our TFF platform can be used to formulate a dry powder version of Voriconazole,
generally considered to be one of the best antifungal drugs used in the treatment of IPA. Voriconazole is an off-patent drug and our TFF prepared version of
Voriconazole would represent the first inhaled antifungal medication for the treatment of IPA, which has the potential to put the drug exactly where it is
needed while minimizing off target effects.

Voriconazole  is  currently  marketed  in  Australia,  Europe  and  the  U.S.  as  Vfend,  and  is  available  in  several  strengths  and  presentations  for  oral
delivery or IV infusion. As of the date of this report, the Clinical Practice Guidelines released by the Infectious Diseases Society of America recommend
Voriconazole as first-line monotherapy for IPA. However, since the registration of Vfend in Europe and the U.S. in 2002, several studies have examined the
exposure-response relationship with Voriconazole, identifying a relationship between low Voriconazole exposure and higher rates of treatment failure, as
well as a higher propensity for neurotoxicity at higher exposures. Studies have shown that when delivered orally or intravenously Voriconazole can have
differing bioavailability, and therefore differing concentration of the drug available to the lungs, based on whether the patient recently had food. In addition,
Voriconazole  when  delivered  orally  or  intravenously  has  been  shown  to  have  various  side  effects  including  nausea  and  headaches,  and  adverse  events
including  optic  neuritis  and  papilledema,  hepatic  toxicity,  galactose  intolerance,  arrhythmias  and  QT  prolongation.  These  studies  confirm  that  when
administered orally or intravenously, Voriconazole provides a narrow therapeutic window between treatment failure and unacceptable treatment toxicity.

We  believe  a  TFF  prepared  dry  powder  formulation  of  Voriconazole  can  maximize  both  the  prophylactic  value  to  the  lungs  for
immunocompromised  patients  susceptible  to  IPA  and  the  treatment  value  of  patients  suffering  from  chronic  IPA.  We  also  believe  our  dry  powder  drug
would  benefit  patients  by  providing  the  drug  at  the  “port  of  entry”  of  invasive  fungal  infections,  while  also  reducing  or  eliminating  the  unpleasant  and
potentially fatal side effects associated with Voriconazole and other last line antifungals. We also believe that the administration of our TFF prepared dry
powder  formulation  directly  to  the  lungs  will  significantly  reduce  any  potential  differences  in  bioavailability  due  to  the  effects  of  eating  or  fasting.  In
addition, animal and in vitro studies have shown that our TFF prepared dry powder formulation will improve the solubility of Voriconazole compared to
oral  or  intravenous  delivery.  We  believe  that  the  combination  of  improved  solubility  and  direct-to-lung  administration  of  our  TFF  prepared  dry  powder
formulation  will  allow  for  a  lower  dose  directly  to  the  lungs  and  thereby  reduce  the  high  systemic  exposure  of  oral  administration  and  associated  side
effects, including optic neuritis and papilledema, hepatic toxicity, galactose intolerance, arrhythmias and QT prolongation.

Through our work with UT, we have already completed performance characterization of a TFF formulation of Voriconazole, early animal model
testing and, in 2018, a seven-day toxicology study in rats. Through our drug characterization activities, we have worked with researchers at UT to define
the  appropriate  dosage,  particle  size,  porosity,  density  and  other  dosage  characteristics  of  a  TFF  prepared  dry  powder  formulation  of  Voriconazole  and
related  excipients.  Previous  third-party  studies  suggest  that  inhaled  Voriconazole  may  be  effective  in  animal  models  and  as  a  therapy  in  humans  when
delivered to the lung by nebulization. Our TFF formulation of Voriconazole has been used to produce a 95% Voriconazole powder for inhalation that has
been tested in rats and at inhaled doses up to 4 mg/kg, with no local or systemic toxicity while showing good exposure in lung tissue and plasma.

On February 4, 2019, we participated in a pre-IND meeting with the FDA for purposes of discussing our proposed regulatory pathway for TFF
Vori  and  obtaining  guidance  from  the  FDA  on  the  pre-clinical  plan  leading  to  the  filing  and  acceptance  of  an  IND  application  for  TFF  Vori.  We  were
successful in gaining agreement that a 505(b)(2) approach would be appropriate for TFF Vori. However, the FDA requested that we perform an additional
28-day toxicity study in rats and a 14-day study in dogs, both of which have been completed, as well as a Phase I study in healthy human subjects. In
October 2019, we submitted to the FDA an IND for our TFF Vori and initiated our Phase I human clinical trials in November 2019. In addition, we believe
we  will  need  to  complete  a  Phase  II  study  prior  to  filing  for  marketing  approval.  However,  there  can  be  no  assurance  that  the  FDA  will  not  ask  for
additional clinical data. We also believe that our dry powder formulation may qualify as an orphan drug, as there are an estimated 50,000 transplants in the
U.S. each year as well as approximately 50,000 patients suffering with chronic IPA.

TFF Tac-Lac — For Immunosuppression to Prevent Organ Transplant Rejection

We  are  developing  TFF  Tac-Lac,  a  dry  powder  version  of  Tacrolimus,  an  immunosuppressive  drug  used  in  transplant  medicine.  Prograf
Tacrolimus is currently the second most commonly administered immunosuppressive agent in solid organ transplantation despite what we believe to be the
many challenges for patients and physicians when used for extended periods. Prograf Tacrolimus can cause nephrotoxicity, particularly when used in high
doses.  According  to  product  labeling  and  prescribing  information  for  Prograf  Tacrolimus,  nephrotoxicity  was  reported  in  approximately  52%  of  kidney
transplantation patients and in 40% and 36% of liver transplantation patients receiving Prograf in the U.S. and European randomized trials, respectively,
and in 59% of heart transplantation patients in a European randomized trial.

Although Tacrolimus has been shown via animal models to be beneficial for a number of immunological diseases that affect the lung, systemic
toxicity (including renal failure, hypertension, hirsutism, diabetes) has limited its use. In addition, Tacrolimus when delivered orally or intravenously has
been shown to have side effects including nausea, indigestion, stomach pain and headaches. Adverse events associated with Tacrolimus when delivered
orally or intravenously include increase in cancer, increase in infections, anemia, kidney problems, nervous system problems (including seizures, coma,
tremors, confusion, headaches), high blood pressure, QT prolongation, high level of potassium in the blood, myocardial hypertrophy, diabetes, damage to
the brain, high level of fats or lipids or phosphates in the blood, constipation, diarrhea, bronchitis, inability to sleep, high magnesium levels, reduction in
white blood cells, lack of energy, damage to the peripheral nerves, and fluid around the heart.

Tacrolimus  is  an  off-patent  drug  and  we  intend  to  develop  a  dry  powder  version  suitable  for  use  with  a  dry  powder  inhaler.  Because  our  dry
powder  version  would  provide  for  a  high  local  lung  concentration  without  the  typical  systemic  toxicity  frequently  experienced  with  oral  dosage  form
immunosuppressants, we believe our drug candidate should have a high likelihood of success in competing in the immunosuppressant market for lung and
heart/lung transplants.

Through our partners at UT, we have already completed development work and performance characterization of our dry powder formulation of
Tacrolimus  through  early  animal  modeling  testing.  Through  our  drug  characterization  activities,  we  have  worked  with  researchers  at  UT  to  define  the
particle size, distribution and aerodynamic properties suitable for delivery to humans using a dry powder inhaler. Past third-party studies report that inhaled
Tacrolimus delivered to the lungs by nebulization has proven to produce robust drug levels in lung tissue, while the drug level is reduced in peripheral
tissues, where toxicity limits dosing. Our TFF formulation of Tacrolimus has been used to produce a 50% Tacrolimus powder for inhalation that has been
tested in rats. The inhaled doses in our animal tests exhibited higher pulmonary bioavailability with a prolonged retention time in the lung. In addition, our
TFF formulation generated a lower systemic concentration of Tacrolimus, thereby suggesting the possibility of reduced side effects compared to oral or
intravenous delivery.

On September 26, 2019, we participated in a pre-IND meeting with the FDA for purposes of discussing our proposed regulatory pathway for TFF
Tac-Lac and obtaining guidance from the FDA on the pre-clinical plan leading to the filing and acceptance of an IND application for TFF Tac-Lac. We
were successful in gaining agreement that a 505(b)(2) approach would be appropriate for TFF Tac-Lac. However, since we are pursuing a new indication in
the treatment of prophylaxis of organ rejection in patients receiving lung transplants, the FDA confirmed our expectation that we will probably need to
complete a Phase I and a Phase IIb/IIIa study prior to filing for marketing approval for TFF Tac-Lac. The proposed Phase IIb/IIIa study would essentially
be a Phase II clinical study but would include more rigorous and expansive controlled and uncontrolled clinical trials for purposes of generating greater
data on efficacy, dosing and labeling. However, there can be no assurance that the FDA will not ask for additional clinical data. We also believe that our dry
powder formulation may qualify as an orphan drug, as there are an estimated 50,000 transplants in the U.S. each year.We intend to conduct Phase 1 clinical
trials for our TFF formulation of Tacrolimus in Australia, which we consider to be a highly desirable site to conduct human clinical trials.  On March 13,
2020, we had received the approval of the Australian Human Research Ethics Committee to commence Phase 1 trials in Australia.  However, later in March
2020, our contract research organization partner in Australia informed us that because of the spread of the COVID-19 virus in Australia, there would be a
delay in initiating the trials.  One contributing factor is that Tacrolimus is an immunosuppressant drug and, given the threat of the COVID-19 virus, concern
exists that even though we would be dosing healthy volunteers the inhalation of an immunosuppressant could increase the risk of severe complications if a
volunteer  was  to  contract  COVID-19.    As  of  the  date  of  this  report,  we  are  unable  to  predict  the  length  of  the  delay  in  the  commencement  of  Phase  1
clinical trials for our TFF Tac-Lac.  As of the date of this report, we intend to submit to the FDA an IND for TFF Tac-Lac upon completion of the Phase 1
clinical trials.

Triple Combination For COPD/Asthma

We are developing a dry powder drug combination intended to treat chronic obstructive pulmonary disease, or COPD, and asthma. There is a trend
towards a three-drug combination in the treatment of uncontrolled COPD and asthma. Data suggests that therapy with a long-acting antimuscarinic agent,
or LAMA, a long-acting β2-agonist, or LABA, and an inhaled corticosteroid, or ICS, is effective in patients with severe COPD. GSK has received FDA
approval for a triple combination drug, Trelegy Ellipta, for the treatment of pulmonary disease. In addition, a variety of triple combinations are currently
under development by large pharmaceutical companies, including AstraZeneca and Chiesi Farmaceutici.

We are currently pursuing the development of a combination dry powder drug intended for use with a dry powder inhaler for the maintenance
treatment  of  bronchospasm  associated  with  moderate  to  severe  COPD.  Unlike  most  other  triple  combinations,  which  are  chosen  in  part  from  the
pharmaceutical company’s list of existing products, our triple combination drug contains what we consider will be the best-in-class drug in each category of
LAMA, LABA and ICS.

Each of the drugs in our proposed dry powder triple combination is currently off-patent and each is available for delivery individually by way of
breath-actuated inhalers. However, the three drugs in combination are not available for delivery through any breath-actuated inhalers due to the inability to
deliver the drugs through the airway in the exact ratio designed for treatment. We believe, however, that our TFF platform allows for all three drugs to end
up in each particle delivered to the airway in the exact ratio designed for treatment.

Since competition exists, and typically large clinical trials are needed to approve this type of triple combination drug, our strategy would be to
develop the triple combination dry powder drug in partnership with a large pharmaceutical company looking to compete in the COPD and asthma markets.
We intend to engage large pharmaceutical companies in discussions concerning a potential joint development of our triple combination dry powder drug.
However, as of the date of this report we have no agreements, understandings or arrangements concerning a joint development program and there can be no
assurance we will be able to enter into a joint development agreement on terms acceptable to us. We do not intend to pursue the development of our triple
combination dry powder drug beyond performance characterization and efficacy data through early animal testing until such time, if ever, as we obtain a
development partner.

Other Potential Dry Powder Products

Our  business  model  is  to  develop  proprietary  innovative  drug  product  candidates  that  offer  commercial  or  functional  advantages,  or  both,  to
currently available alternatives. In our initial evaluation of the market, we have identified a number of potential drug candidates that show promise upon
initial assessment, for two of which we have conducted meaningful development activities, including dry powder formulations of:

● Cannabidiol, or CBD, a controlled substance as defined in the federal Controlled Substances Act of 1970, or CSA, that is reported to be used
by some for the treatment of various epilepsy syndromes as well as anxiety, insomnia, and different types of pain. We are in the early stages of
developing  an  inhaled  dry  powder  drug  that  could  be  used  to  support  or  to  treat  a  variety  of  health  issues  that  may  benefit  from  CBD
administration.  Researchers  have  explored  using  the  broader  class  of  cannabinoids  for  inflammation,  symptoms  of  multiple  sclerosis,
anorexia, schizophrenia, and other conditions. The FDA has approved Epidiolex for the treatment of seizures associated with Lennox-Gastaut
syndrome or Dravet syndrome in patients two years of age or older. The Epidiolex product is an oral solution containing 100 mg/mL of CBD.

9

 
 
 
 
 
 
 
 
 
 
We believe, and early in-vitro research confirms, that our TFF platform can be used to formulate a dry powder version of CBD. Through our
work with UT, early animal model testing of TFF formulations of CBD administered via inhalation have been completed. The inhaled CBD
showed more sustained pharmacokinetic blood levels compared to the IV delivery method in the animal studies.

We  intend  to  engage  pharmaceutical  and  non-pharmaceutical  companies  in  the  CBD  space  in  discussions  concerning  a  potential  joint
development of our dry powder formulation of CBD, which may target a CBD drug product subject to FDA regulation or a non-drug CBD
product that may not be subject to FDA approval. We do not intend to pursue the development of our dry powder formulation of a CBD drug
product  beyond  performance  characterization  and  efficacy  data  through  early  animal  testing  until  such  time,  if  ever,  as  we  obtain  a  drug
development partner. There can be no assurance that our early testing and development will lead to a commercial dry powder formulation of a
CBD drug product.

The 2018 Farm Bill, which was signed into law on December 20, 2018, liberalized to some degree the regulation of hemp and hemp-derived
products,  such  as  CBDs,  under  the  CSA.  However,  the  2018  Farm  Bill  did  not  alter  the  FDA’s  authority  to  regulate  products  containing
cannabis or cannabis-derived compounds, including CBD, under the Federal Food, Drug, and Cosmetic Act, or the FDCA. Following passage
of  the  2018  Farm  Bill,  the  FDA  reaffirmed  its  enforcement  authority  and  reiterated  the  requirement  that  a  CBD  product  (hemp-derived  or
otherwise) that is marketed with a claim of therapeutic benefit, or with any other disease claim, be approved by the FDA for its intended use
before  it  may  be  introduced  into  interstate  commerce.  However,  we  believe  that  CBD  products  that  are  not  marketed  with  a  claim  of
therapeutic benefit, or with any other disease claim, and meet the requirements of a dietary supplement, may not require FDA pre-marketing
approval. Hemp products, including CBDs, that qualify as drugs, food, dietary supplements, veterinary products, and cosmetics will continue
to be regulated by the FDA under the applicable regulatory frameworks. As of the date of this report, we believe that Epidiolex is the only
CBD-based product that has received market approval from the FDA.

● Vaccines containing aluminum salts, which make up approximately 35% of all vaccines. Aluminum salts are incorporated into many vaccine
formulations  as  an  adjuvant,  which  is  a  substance  added  to  vaccines  to  enhance  the  immune  response  of  vaccinated  individuals.  A  major
limitation with these vaccines is that they are very fragile and to maintain their efficacy they must be formulated as liquid suspensions and
kept in a cold chain (2–8°C) during transport and storage, which is burdensome and expensive. Also, exposure of the liquid vaccines to either
ambient or freezing temperatures will cause a loss of efficacy, including particle aggregation in the case of freezing. Alternatives to cold chain
have been examined, including the introduction of stabilizing agents in vaccines to prevent aggregation during freezing and the application of
novel freezing and drying techniques; however, we believe that to date none of these techniques have led to an acceptable alternative to cold
chain.

We have conducted drug and performance characterization activities of certain TFF formulated salt containing vaccines. Our activities suggest
that  the  salt  containing  vaccines  can  be  successfully  converted  from  liquid  suspension  into  dry  powder  using  our  TFF  platform  using  a
relatively low concentration of trehalose as an excipient, and that the dry powder can later be reconstituted at the time of use without causing
particle aggregation or decrease in efficacy. In addition, the dry vaccine powder did not aggregate after repeated dry-freezing-and-thawing.
We  believe  that  the  TFF  platform  may  be  used  to  formulate  new  vaccines,  or  to  reformulate  existing  vaccines,  that  are  adjuvanted  with
aluminum salts into dry vaccine powder without significant loss of efficacy.

We  intend  to  engage  pharmaceutical  companies  in  the  vaccine  space  in  discussions  concerning  a  potential  joint  development  of  TFF
formulated salt containing vaccines and, in the meantime, we do not intend to pursue the development of our dry powder formulation of salt
containing vaccines beyond performance characterization and efficacy data through early animal testing until such time, if ever, as we obtain
a development partner. There can be no assurance, however, that our early testing and development will lead to a commercial dry powder
formulation of salt containing vaccines.

We have identified a number of additional drug candidates that show promise upon initial evaluation. In each case, these are drugs for which we
would  directly  pursue  the  development  of  a  dry  powder  formulation  for  use  through  a  dry  powder  inhaler.  We  have  not  commenced  meaningful
development activities for any of these product candidates at this time and there can be no assurance that we will pursue any of the product candidates
below.

We believe that our TFF technology provides a very diverse and effective way to develop solutions for lung specific disorders. Many potentially
beneficial drugs for lung diseases and disorders are unable to be dosed in high enough concentration to provide therapeutic benefit to the lung due to the
systemic nature (oral or IV dosing) of the drug leading to toxicity of the kidney, lungs and other systemic safety concerns. We believe our TFF platform has
the potential to take these difficult to formulate drugs and develop products to be delivered directly to the lung for treatment of lung diseases and disorders.
This direct dosing may reduce plasma levels and has the potential to increase efficacy while reducing side effects.

We  believe  that  all  of  the  above  potential  drug  candidates  are  off-patent  drugs  for  which  we  would  directly  pursue  the  development  of  a  dry
powder  formulation  through  the  FDA’s  505(b)(2)  regulatory  pathway.  However,  not  all  of  our  drug  product  candidates  will  target  off-patent  drugs.  For
example,  we  do  not  expect  our  proposed  dry  powder  formulation  of  CBD  to  be  off-patent  and  our  proposed  dry  powder  formulation  of  aluminum  salt
vaccines may not be off-patent. We also expect that our dry powder formulation of a CBD drug product will likely require a full NDA through the FDA’s
505(b)(1) regulatory pathway and that our dry powder formulation of aluminum salt vaccines will require a biological license application, or BLA, which is
very similar to a full NDA through the FDA’s 505(b)(1) regulatory pathway.

Licenses and Intellectual Property Rights

We hold rights to our TFF technology pursuant to a patent license agreement entered into in July 2015, between University of Texas at Austin, or
UT, and our former parent, LTI, which LTI assigned to us in March 2018, as amended by UT and us on November 30, 2018. UT is the owner of 39 U.S.
and international patents and patent applications with claims covering the TFF platform. Pursuant to the amended patent license agreement, we hold an
exclusive  worldwide,  royalty  bearing  license  to  the  rights  to  the  aforementioned  patents,  including  any  divisionals,  continuations  and  extensions,  in  all
fields of use.

11

 
 
 
 
 
 
 
 
 
 
We are required to pay royalties to UT in the amount of 2% of net sales received by us from the sale of products covered by the licensed patent
rights. We will also be required to make certain milestone payments to UT in connection with the certain regulatory submissions and approvals and pay
fees in connection with any assignments or sublicenses, including:

● $50,000 upon each approval of an IND for the first indication of each product candidate;

● $100,000 upon submission of a final Phase II report (or a foreign equivalent) on the first product candidate;

● $250,000 upon submission of a final Phase III report (or a foreign equivalent) on the first product candidate;

● $500,000 upon regulatory approval in the U.S. (or a foreign equivalent) on the first product candidate;

● $500,000 upon regulatory approval in the U.S. (or a foreign equivalent) on the second product candidate or on the second indication of the

first product candidate; and

● Our issuance to UT of one percent (1%) of our outstanding common stock, calculated on a fully-diluted basis, upon and as of our first IND

approval for a product candidate.

Pursuant to the UT patent license agreement, UT has agreed to consult with us concerning the development and implementation of a strategy for
the prosecution and maintenance of the licensed patent rights, including any infringement of the licensed patents rights by third-parties. However, UT has
retained  control  and  final  decision-making  authority  over  such  matters.  We  are  responsible  for  the  payment  of  all  fees  and  expenses  involved  in  the
prosecution  and  maintenance  of  the  licensed  patent  rights  and  are  obligated  to  negotiate  in  good  faith  with  UT  over  the  funding  and  allocation  of  any
recovery involved in any patent infringement action brought to enforce the licensed patent rights, which are presently scheduled to expire over a period of
time commencing in 2023 and ending in 2035. The term of the UT patent license agreement is co-terminus with the licensed patent rights. However, UT
has the right to terminate the patent license agreement, or any part of the licensed patent rights or field of use, in the event of our breach of any provision of
the  patent  license  agreement  that  remains  uncured  after  UT’s  written  notice  of  breach  and  an  applicable  cure  period  or  in  the  event  we  initiate  any
proceeding to challenge the validity or scope of the licensed patent rights. The agreement also contains customary representations, warranties, covenants
and indemnities by the parties.

In  addition  to  the  licensed  patent  rights,  we  also  rely  on  our  trade  secrets,  know-how  and  continuing  technological  innovation  to  develop  and
maintain  our  proprietary  position.  We  will  vigorously  defend  our  intellectual  property  to  preserve  our  rights  and  gain  the  benefit  of  our  technological
investments.

Government Regulations and Funding

Pharmaceutical  companies  are  subject  to  extensive  regulation  by  foreign,  federal,  state  and  local  agencies,  such  as  the  U.S.  FDA,  and  various
similar  agencies  in  most  countries  worldwide.  The  manufacture,  distribution,  marketing  and  sale  of  pharmaceutical  products  are  subject  to  government
regulation in the U.S. and various foreign countries. Additionally, in the U.S., we must follow rules and regulations established by the FDA requiring the
presentation of data indicating that our product candidates are safe and efficacious and are manufactured in accordance with cGMP regulations. If we do
not comply with applicable requirements, we may be fined, the government may refuse to approve our marketing applications or allow us to manufacture
or market our product candidates, and we may be criminally prosecuted. We, our manufacturers and clinical research organizations, may also be subject to
regulations  under  other  foreign,  federal,  state  and  local  laws,  including,  but  not  limited  to,  the  U.S.  Occupational  Safety  and  Health  Act,  the  Resource
Conservation and Recovery Act, the Clean Air Act and import, export and customs regulations as well as the laws and regulations of other countries. The
U.S. government has increased its enforcement activity regarding illegal marketing practices domestically and internationally. As a result, pharmaceutical
companies must ensure their compliance with the Foreign Corrupt Practices Act and federal healthcare fraud and abuse laws, including the False Claims
Act.

These regulatory requirements impact our operations and differ from one country to another, so that securing the applicable regulatory approvals
of one country does not imply the approval of another country. The approval procedures involve high costs and are manpower intensive, usually extend
over many years and require highly skilled and professional resources.

FDA Market Approval Process

The steps usually required to be taken before a new drug may be marketed in the U.S. generally include:

● completion of pre-clinical laboratory and animal testing;

● completion of required chemistry, manufacturing and controls testing;

● the  submission  to  the  FDA  of  an  IND,  which  must  be  evaluated  and  found  acceptable  by  the  FDA  before  human  clinical  trials  may

commence;

● performance of adequate and well-controlled human clinical trials to establish the safety, pharmacokinetics and efficacy of the proposed drug

for its intended use;

● submission and approval of an NDA;

● successful pre-approval inspection of the manufacturer and analytical testing facilities; and

● agreement with FDA of the label language, including the prescribing information insert.

Clinical  studies  are  conducted  under  protocols  detailing,  among  other  things,  the  objectives  of  the  study,  what  types  of  patients  may  enter  the
study, schedules of tests and procedures, drugs, dosages, and length of study, as well as the parameters to be used in monitoring safety, and the efficacy
criteria  to  be  evaluated.  A  protocol  for  each  clinical  study  and  any  subsequent  protocol  amendments  must  be  submitted  to  the  FDA  as  part  of  the  IND
process.

Clinical trials are usually conducted in three phases. Phase I clinical trials are normally conducted in small groups of healthy volunteers to assess
safety  and  tolerability  of  various  dosing  regimens  and  pharmacokinetics.  After  a  safe  dose  has  been  established,  in  Phase  II  clinical  trials  the  drug  is
administered to small populations of sick patients to look for initial signs of efficacy via dose ranging studies in treating the targeted disease or condition
and to continue to assess safety and the effective doses to be studied in larger trials in Phase III. In the case of vaccines, the participants are healthy and the
signs of efficacy can be obtained in early Phase I, therefore this Phase is defined as Phase I/II. Phase III clinical trials are usually multi-center, double-blind
controlled trials in hundreds or even thousands of subjects at various sites to assess as fully as possible both the safety and effectiveness of the drug.

Clinical trials must be conducted in accordance with the FDA’s good clinical practice, or GCP, requirements. The FDA may order the temporary or
permanent discontinuation of a clinical study at any time or impose other sanctions if it believes that the clinical study is not being conducted in accordance
with FDA requirements or that the participants are being exposed to an unacceptable health risk. An institutional review board, or IRB, generally must
approve  the  clinical  trial  design  and  patient  informed  consent  at  study  sites  that  the  IRB  oversees  and  also  may  halt  a  study,  either  temporarily  or
permanently, for failure to comply with the IRB’s requirements, or may impose other conditions. Additionally, some clinical studies are overseen by an
independent  group  of  qualified  experts  organized  by  the  clinical  study  sponsor,  known  as  a  data  safety  monitoring  board  or  committee.  This  group
recommends whether or not a trial may move forward at designated check points based on access to certain data from the study. The clinical study sponsor
may also suspend or terminate a clinical trial based on evolving business objectives and/or competitive climate.

13

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
As a product candidate moves through the clinical testing phases, manufacturing processes are further defined, refined, controlled and validated.
The level of control and validation required by the FDA increases as clinical studies progress. We and the third-party manufacturers on which we rely for
the manufacture of our product candidates and their respective components (including the API) are subject to requirements that drugs be manufactured,
packaged and labeled in conformity with cGMPs. To comply with cGMP requirements, manufacturers must continue to spend time, money and effort to
meet  requirements  relating  to  personnel,  facilities,  equipment,  production  and  process,  labeling  and  packaging,  quality  control,  recordkeeping  and  other
requirements.

Assuming  completion  of  all  required  testing  in  accordance  with  all  applicable  regulatory  requirements,  detailed  information  on  the  product
candidate is submitted to the FDA in the form of an NDA, requesting approval to market the product for one or more indications, together with payment of
a user fee, unless waived. An NDA includes all relevant data available from pertinent nonclinical and clinical studies, including negative or ambiguous
results as well as positive findings, together with detailed information on the chemistry, manufacture, controls and proposed labeling, among other things.
To support marketing approval, the data submitted must be sufficient in quality and quantity to establish the safety and efficacy of the product candidate for
its intended use to the satisfaction of the FDA. The FDA also conducts a pre-approval inspection of the manufacturer and laboratory prior to approval of the
NDA.

If  an  NDA  submission  is  accepted  for  filing,  the  FDA  begins  an  in-depth  review  of  the  NDA.  Under  the  Prescription  Drug  User  Fee  Act,  or
PDUFA, the FDA’s goal is to complete its initial review and respond to the applicant within ten months of submission, unless the application relates to an
unmet  medical  need,  or  is  for  a  serious  or  life-threatening  indication,  in  which  case  the  goal  may  be  within  six  months  of  NDA  submission.  However,
PDUFA goal dates are not legal mandates and the FDA response often occurs several months beyond the original PDUFA goal date. Further, the review
process and the target response date under PDUFA may be extended if the FDA requests or the NDA sponsor otherwise provides additional information or
clarification regarding information already provided in the NDA. The NDA review process can, accordingly, be very lengthy. During its review of an NDA,
the FDA may refer the application to an advisory committee for review, evaluation and recommendation as to whether the application should be approved.
The FDA is not bound by the recommendation of an advisory committee, but it typically follows such recommendations. Data from clinical studies are not
always conclusive and the FDA and/or any advisory committee it appoints may interpret data differently than the applicant.

After the FDA evaluates the NDA and inspects manufacturing facilities where the drug product and/or its API will be produced and tested, it will
either approve commercial marketing of the drug product with prescribing information for specific indications or issue a complete response letter indicating
that the application is not ready for approval and stating the conditions that must be met in order to secure approval of the NDA. If the complete response
letter requires additional data and the applicant subsequently submits that data, the FDA nevertheless may ultimately decide that the NDA does not satisfy
its criteria for approval. The FDA could also approve the NDA with a Risk Evaluation and Mitigation Strategies, or REMS, plan to mitigate risks, which
could include medication guides, physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries
and other risk minimization tools. The FDA also may condition approval on, among other things, changes to proposed labeling, development of adequate
controls  and  specifications,  or  a  commitment  to  conduct  post-marketing  testing.  Such  post-marketing  testing  may  include  Phase  IV  clinical  trials  and
surveillance to further assess and monitor the product’s safety and efficacy after approval. Regulatory approval of products for serious or life-threatening
indications may require that participants in clinical studies be followed for long periods to determine the overall survival benefit of the drug.

If the FDA approves one of our product candidates, we will be required to comply with a number of post-approval regulatory requirements. We
would  be  required  to  report,  among  other  things,  certain  adverse  reactions  and  production  problems  to  the  FDA,  provide  updated  safety  and  efficacy
information and comply with requirements concerning advertising and promotional labeling for any of our product candidates. Also, quality control and
manufacturing  procedures  must  continue  to  conform  to  cGMPs  after  approval,  and  the  FDA  periodically  inspects  manufacturing  facilities  to  assess
compliance  with  cGMPs,  which  imposes  extensive  procedural,  substantive  and  record  keeping  requirements.  If  we  seek  to  make  certain  changes  to  an
approved product, such as certain manufacturing changes, we may need FDA review and approval before the change can be implemented.

14

 
 
 
 
 
 
 
While  physicians  may  use  products  for  indications  that  have  not  been  approved  by  the  FDA,  we  may  not  label  or  promote  the  product  for  an
indication  that  has  not  been  approved.  Securing  FDA  approval  for  new  indications  is  similar  to  the  process  for  approval  of  the  original  indication  and
requires,  among  other  things,  submitting  data  from  adequate  and  well-controlled  studies  that  demonstrate  the  product’s  safety  and  efficacy  in  the  new
indication. Even if such studies are conducted, the FDA may not approve any change in a timely fashion, or at all.

The FDA may also require post-marketing testing, or Phase IV testing, as well as risk minimization action plans and surveillance to monitor the

effects of an approved product or place conditions or an approval that could otherwise restrict the distribution or use of the product.

Section 505(b)(2) New Drug Applications

We intend to submit applications for both of our lead therapeutic candidates via the 505(b)(2) regulatory pathway. As an alternate path for FDA
approval  of  new  indications  or  new  formulations  of  previously-approved  products,  a  company  may  file  a  Section  505(b)(2)  NDA,  instead  of  a  “stand-
alone”  or  “full”  NDA.  Section  505(b)(2)  of  the  FDCA  was  enacted  as  part  of  the  Drug  Price  Competition  and  Patent  Term  Restoration  Act  of  1984,
otherwise  known  as  the  Hatch-Waxman  Amendments.  Section  505(b)(2)  permits  the  submission  of  an  NDA  where  at  least  some  of  the  information
required for approval comes from studies not conducted by or for the applicant and for which the applicant has not obtained a right of reference. Some
examples of products that may be allowed to follow a 505(b)(2) path to approval are drugs that have a new dosage form, strength, route of administration,
formulation or indication.

The Hatch-Waxman Amendments permit the applicant to rely upon certain published nonclinical or clinical studies conducted for an approved
product or the FDA’s conclusions from prior review of such studies. The FDA may require companies to perform additional studies or measurements to
support  any  changes  from  the  approved  product.  The  FDA  may  then  approve  the  new  product  for  all  or  some  of  the  labeled  indications  for  which  the
reference product has been approved, as well as for any new indication supported by the Section 505(b)(2) application. While references to nonclinical and
clinical data not generated by the applicant or for which the applicant does not have a right of reference are allowed, all development, process, stability,
qualification and validation data related to the manufacturing and quality of the new product must be included in an NDA submitted under Section 505(b)
(2).

To  the  extent  that  the  Section  505(b)(2)  applicant  is  relying  on  the  FDA’s  conclusions  regarding  studies  conducted  for  an  already  approved
product, the applicant is required to certify to the FDA concerning any patents listed for the approved product in the FDA’s Approved Drug Products with
Therapeutic Equivalence Evaluations, or Orange Book. Specifically, the applicant must certify that: (i) the required patent information has not been filed;
(ii) the listed patent has expired; (iii) the listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or
(iv) the listed patent is invalid or will not be infringed by the new product. The Section 505(b)(2) application also will not be approved until any non-patent
exclusivity, such as exclusivity for obtaining approval of a new chemical entity, listed in the Orange Book for the reference product has expired. If the
Orange Book certifications outlined above are not accomplished, the Section 505(b)(2) applicant may invest a significant amount of time and expense in
the development of its products only to be subject to significant delay and patent litigation before its products may be commercialized.

Orphan Drugs

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug intended to treat a rare disease or condition affecting fewer than
200,000  individuals  in  the  United  States,  or  in  other  limited  cases.  Orphan  drug  designation  (ODD)  provides  for  seven  years  of  market  exclusivity,
independent of patent protection, to the company with ODD that brings a particular product to market. In addition, companies developing orphan drugs are
eligible  for  certain  incentives,  including  tax  credits  for  qualified  clinical  testing.  In  addition,  an  NDA  for  a  product  that  has  received  orphan  drug
designation is not subject to a prescription drug user fee unless the application includes an indication other than the rare disease or condition for which the
drug was designated.

15

 
 
 
 
 
 
 
 
 
 
To gain exclusivity, if a product that has orphan drug designation subsequently receives the first FDA approval for the disease or condition for
which it has such designation, the product is entitled to the orphan drug exclusivity, which means that the FDA may not approve any other applications to
market  the  same  active  moiety  for  the  same  indication  for  seven  years,  except  in  limited  circumstances,  such  as  another  drug’s  showing  of  clinical
superiority over the drug with orphan exclusivity. Competitors, however, may receive approval of different active moieties for the same indication or obtain
approval for the same active moiety for a different indication. In addition, doctors may prescribe products for off-label uses and undermine our exclusivity.
Orphan drug exclusivity could block the approval of one of our product candidates for seven years if a competitor obtains approval for the same active
moiety for the same indication before we do, unless we are able to demonstrate that our product is clinically superior.

We may plan to pursue orphan drug designation and exclusivity for some of our product candidates in the United States, European Union, and
other geographies of interest for specific products. We cannot guarantee that we will obtain orphan drug designation for any products in any jurisdiction.
Even if we are able to obtain orphan drug designation for a product, we cannot be sure that such product will be approved, that we will be able to obtain
orphan drug exclusivity upon approval, if ever, or that we will be able to maintain any exclusivity that is granted.

Continuing Regulation

After a drug is approved for marketing and enters the marketplace, numerous regulatory requirements continue to apply. These include, but are not

limited to:

● the FDA’s cGMP regulations require manufacturers, including third party manufacturers, to follow stringent requirements for the methods,

facilities and controls used in manufacturing, processing and packing of a drug product;

● labeling  regulations  and  the  FDA  prohibitions  against  the  promotion  of  drugs  for  unapproved  uses  (known  as  off-label  uses),  as  well  as

requirements to provide adequate information on both risks and benefits during promotion of the drug;

● approval of product modifications or use of a drug for an indication other than approved in an NDA;

● adverse drug experience regulations, which require us to report information on adverse events during pre-market testing and post-approval

safety reporting;

● NDA  quarterly  reporting  for  the  first  three  years,  then  annual  reporting  thereafter,  of  changes  in  chemistry,  manufacturing  and  control  or

CMC, labeling, clinical studies and findings, and toxicology studies from the data submitted in the NDA;

● post-market  testing  and  surveillance  requirements,  including  Phase  IV  trials,  when  necessary  to  protect  the  public  health  or  to  provide

additional safety and effectiveness data for the drug; and

● the FDA’s recall authority, whereby it can ask, or under certain conditions order, drug manufacturers to recall from the market a product that is
in violation of governing laws and regulation. After a drug receives approval, any modification in conditions of use, active ingredient(s), route
of administration, dosage form, strength or bioavailability, will require a new approval, for which it may be possible to submit a 505(b)(2),
accompanied  by  additional  clinical  data  necessary  to  demonstrate  the  safety  and  effectiveness  of  the  product  with  the  proposed  changes.
Additional clinical studies may be required for proposed changes.

Other U.S. Healthcare Laws and Compliance Requirements

For  products  distributed  in  the  United  States,  we  will  also  be  subject  to  additional  healthcare  regulation  and  enforcement  by  the  federal

government and the states in which we conduct our business. Applicable federal and state healthcare laws and regulations include the following:

● The  federal  healthcare  anti-kickback  statute  prohibits,  among  other  things,  persons  from  knowingly  and  willfully  soliciting,  offering,
receiving, or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or
the purchase, order, or recommendation of, any good or service, for which payment may be made under federal healthcare programs such as
Medicare and Medicaid;

16

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● The  Ethics  in  Patient  Referrals  Act,  commonly  referred  to  as  the  Stark  Law,  and  its  corresponding  regulations,  prohibit  physicians  from
referring patients for designated health services (including outpatient drugs) reimbursed under the Medicare or Medicaid programs to entities
with  which  the  physicians  or  their  immediate  family  members  have  a  financial  relationship  or  an  ownership  interest,  subject  to  narrow
regulatory exceptions, and prohibits those entities from submitting claims to Medicare or Medicaid for payment of items or services provided
to a referred beneficiary;

● The federal False Claims Act imposes criminal and civil penalties, including civil whistleblower or qui tam actions, against individuals or
entities  for  knowingly  presenting,  or  causing  to  be  presented,  to  the  federal  government  claims  for  payment  that  are  false  or  fraudulent  or
making a false statement to avoid, decrease, or conceal an obligation to pay money to the federal government;

● Health  Insurance  Portability  and  Accountability Act  of  1996,  imposes  criminal  and  civil  liability  for  executing  a  scheme  to  defraud  any
healthcare  benefit  program  and  also  imposes  obligations,  including  mandatory  contractual  terms,  with  respect  to  safeguarding  the  privacy,
security  and  transmission  of  individually  identifiable  health  information.  This  statute  also  prohibits  knowingly  and  willfully  falsifying,
concealing  or  covering  up  a  material  fact  or  making  any  materially  false  statement  in  connection  with  the  delivery  of  or  payment  for
healthcare benefits, items, or services; and

● Analogous state laws and regulations, such as state anti-kickback and false claims laws, may apply to sales or marketing arrangements and
claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers, and some state
laws  require  pharmaceutical  companies  to  comply  with  the  pharmaceutical  industry’s  voluntary  compliance  guidelines  and  the  relevant
compliance guidance promulgated by the federal government.

Reimbursement

Sales of our product candidates in the United States may depend, in part, on the extent to which the costs of the product candidates will be covered
by  third-party  payers,  such  as  government  health  programs,  commercial  insurance  and  managed  health  care  organizations.  These  third-party  payers  are
increasingly challenging the prices charged for medical products and services. Additionally, the containment of health care costs has become a priority of
federal  and  state  governments,  and  the  prices  of  drugs  have  been  a  focus  in  this  effort.  The  United  States  government,  state  legislatures  and  foreign
governments  have  shown  significant  interest  in  implementing  cost-containment  programs,  including  price  controls,  restrictions  on  reimbursement  and
requirements for substitution of generic products. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in
jurisdictions with existing controls and measures, could further limit our net revenue and results. If these third-party payers do not consider our product
candidates  to  be  cost-effective  compared  to  other  available  therapies,  they  may  not  cover  our  product  candidates  after  approval  as  a  benefit  under  their
plans or, if they do, the level of payment may not be sufficient to allow us to sell our product candidates on a profitable basis.

17

 
 
 
 
 
 
 
 
The Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or the MMA, imposes new requirements for the distribution and
pricing of prescription drugs for Medicare beneficiaries and includes a major expansion of the prescription drug benefit under Medicare Part D. Under Part
D, Medicare beneficiaries may enroll in prescription drug plans offered by private entities which will provide coverage of outpatient prescription drugs.
Part D plans include both stand-alone prescription drug benefit plans and prescription drug coverage as a supplement to Medicare Advantage plans. Unlike
Medicare Parts A and B, Part D coverage is not standardized. Part D prescription drug plan sponsors are not required to pay for all covered Part D drugs,
and each drug plan can develop its own drug formulary that identifies which drugs it will cover and at what tier or level. However, Part D prescription drug
formularies must include drugs within each therapeutic category and class of covered Part D drugs, though not necessarily all the drugs in each category or
class. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a pharmacy and therapeutic committee. Government
payment for some of the costs of prescription drugs may increase demand for product candidates for which we receive marketing approval. However, any
negotiated prices for our product candidates covered by a Part D prescription drug plan will likely be lower than the prices we might otherwise obtain.
Moreover, while the MMA applies only to drug benefits for Medicare beneficiaries, private payers often follow Medicare coverage policy and payment
limitations in setting their own payment rates. Any reduction in payment that results from the MMA may result in a similar reduction in payments from
non-governmental payers.

On  February  17,  2009,  the  American  Recovery  and  Reinvestment  Act  of  2009  was  signed  into  law.  This  law  provides  funding  for  the  federal
government to compare the effectiveness of different treatments for the same illness. A plan for the research will be developed by the Department of Health
and  Human  Services,  the  Agency  for  Healthcare  Research  and  Quality  and  the  National  Institutes  of  Health,  and  periodic  reports  on  the  status  of  the
research  and  related  expenditures  will  be  made  to  Congress.  Although  the  results  of  the  comparative  effectiveness  studies  are  not  intended  to  mandate
coverage policies for public or private payers, it is not clear how such a result could be avoided and what if any effect the research will have on the sales of
our  product  candidates,  if  any  such  product  or  the  condition  that  it  is  intended  to  treat  is  the  subject  of  a  study.  It  is  also  possible  that  comparative
effectiveness research demonstrating benefits in a competitor’s product could adversely affect the sales of our product candidates. Decreases in third-party
reimbursement  for  our  product  candidates  or  a  decision  by  a  third-party  payer  to  not  cover  our  product  candidates  could  reduce  physician  usage  of  the
product candidates and have a material adverse effect on our sales, results of operations and financial condition.

Employees and Consultants

As of the date of this report, we have four employees, including our executive officers, and several consultants providing technical, financial and

general administrative services.

Item 1A. Risk Factors

Investing in our common stock involves a high degree of risk. Before purchasing our common stock, you should read and consider carefully the
following risk factors as well as all other information contained in this report, including our financial statements and the related notes. Each of these risk
factors, either alone or taken together, could adversely affect our business, operating results and financial condition, as well as adversely affect the value of
an investment in our common stock. There may be additional risks that we do not presently know of or that we currently believe are immaterial, which
could also impair our business and financial position. If any of the events described below were to occur, our financial condition, our ability to access
capital  resources,  our  results  of  operations  and/or  our  future  growth  prospects  could  be  materially  and  adversely  affected  and  the  market  price  of  our
common stock could decline. As a result, you could lose some or all of any investment you may make in our common stock.

Risks Related to Our Business

We  are  a  clinical-stage  biopharmaceutical  company  with  limited  operating  history.  We  are  a  biopharmaceutical  company,  newly-formed  in
January 2018, and have limited operating history. We have not commenced revenue-producing operations. In November 2019, we initiated Phase I human
clinical trials for our TFF Vori product candidate, however, to date, our operations have otherwise consisted of preliminary research and development, drug
formulation  and  characterization  and  testing  of  our  initial  product  candidates.  Our  limited  operating  history  makes  it  difficult  for  potential  investors  to
evaluate  our  technology  or  prospective  operations.  As  a  development  stage  biopharmaceutical  company,  we  are  subject  to  all  the  risks  inherent  in  the
organization, financing, expenditures, complications and delays involved with a new business. Accordingly, you should consider our prospects in light of
the  costs,  uncertainties,  delays  and  difficulties  frequently  encountered  by  companies  in  the  early  stages  of  development,  especially  clinical-stage
biopharmaceutical companies such as ours. Potential investors should carefully consider the risks and uncertainties that a company with a limited operating
history will face. In particular, potential investors should consider that we may be unable to:

● successfully implement or execute our business plan, or ensure that our business plan is sound;

● successfully complete pre-clinical and clinical trials and obtain regulatory approval for the marketing of our product candidates;

● successfully demonstrate a favorable differentiation between our dry powder candidates and the current products on the market;

● successfully contract for the manufacture of our clinical drug products and establish a commercial drug supply;

● secure market exclusivity and/or adequate intellectual property protection for our product candidates;

● attract and retain an experienced management and advisory team; and

● raise sufficient funds in the capital markets to effectuate our business plan, including product and clinical development, regulatory approval

and commercialization for our product candidates.

Investors should evaluate an investment in us in light of the uncertainties encountered by developing companies in a competitive environment.
There can be no assurance that our efforts will be successful or that we will ultimately be able to attain profitability. If we cannot successfully execute any
one of the foregoing, our business may not succeed and your investment will be adversely affected. You must be prepared to lose all of your investment.

We have a history of significant operating losses and anticipate continued operating losses for the foreseeable future. For the fiscal years ended
December 31, 2019 and 2018, we incurred a net loss applicable to common stockholders of $36.7 million and $4.6 million, respectively. As of December
31, 2019, we had an accumulated deficit of $15.7 million. We expect to continue to incur substantial expenses without any corresponding revenues unless
and  until  we  are  able  to  obtain  regulatory  approval  and  successfully  commercialize  at  least  one  of  our  product  candidates.  However,  there  can  be  no
assurance  we  will  be  able  to  obtain  regulatory  approval  for  any  of  our  product  candidates.  Even  if  we  are  able  to  obtain  regulatory  approval  and
subsequently commercialize our product candidates, there can be no assurance that we will generate significant revenues or ever achieve profitability.

19

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We expect to have significant research, regulatory and development expenses as we advance our product candidates towards commercialization.
As a result, we expect to incur substantial losses for the foreseeable future, and these losses will be increasing. We are uncertain when or if we will be able
to  achieve  or  sustain  profitability.  If  we  achieve  profitability  in  the  future,  we  may  not  be  able  to  sustain  profitability  in  subsequent  periods.  Failure  to
become and remain profitable may impair our ability to sustain operations and adversely affect our business and our ability to raise capital. If we are unable
to generate positive cash flow within a reasonable period of time, we may be unable to further pursue our business plan or continue operations, in which
case you may lose your entire investment.

We  expect  we  will  need  additional  financing  to  execute  our  business  plan  and  fund  operations,  which  additional  financing  may  not  be
available  on  reasonable  terms  or  at  all.  As  of  December  31,  2019,  we  had  total  assets  of  approximately  $29.2  million  and  working  capital  of
approximately $28.8 million. As of December 31, 2019, our liquidity included approximately $28.1 million of cash and cash equivalents. We believe that
our cash on-hand as of the date of this report is sufficient to fund our proposed operating plan for, at least, the 12 months following the date of this report.
However, as of the date of this report, we believe that we will need additional capital to fund our operations through to the marketing approval for TFF Vori
and TFF Tac-Lac, assuming such approval can be obtained at all, and to engage in the substantial development of any other of our drug candidates, such as
formulation, early stage animal testing and formal toxicology studies. We intend to seek additional funds through various financing sources, including the
sale of our equity and debt securities, licensing fees for our technology and co-development and joint ventures with industry partners, with a preference
towards licensing fees for our technology and co-development and joint ventures with industry partners. In addition, we will consider alternatives to our
current business plan that may enable to us to achieve revenue producing operations and meaningful commercial success with a smaller amount of capital.
However, there can be no guarantees that such funds will be available on commercially reasonable terms, if at all. If such financing is not available on
satisfactory terms, we may be unable to further pursue our business plan and we may be unable to continue operations, in which case you may lose your
entire investment. 

Our business model is entirely dependent on certain patent rights licensed to us from the University of Texas at Austin, and the loss of those
license  rights  would,  in  all  likelihood,  cause  our  business,  as  presently  contemplated,  to  fail.  In  July  2015,  the  University  of  Texas  at  Austin,  or  UT,
granted to our former parent, LTI, an exclusive worldwide, royalty bearing license to the patent rights for the TFF platform in all fields of use, other than
vaccines. In March 2018, LTI assigned to us all of its interest to the TFF platform, including the patent license agreement with UT. In November 2018, we
and UT amended the patent license agreement such that our exclusive patent rights to the TFF platform were expanded to all fields of use. Our current
business model, which focuses exclusively on the development of drugs using the TFF technology, is based entirely on the availability of the patent rights
licensed to us by UT under the patent license agreement. The patent license agreement requires us to pay royalties and milestone payments and conform to
a variety of covenants and agreements, and in the event of our breach of the agreement, UT may elect to terminate the agreement. As of the date of this
report, we believe we are in compliance with the patent license agreement and consider our relationship with UT to be excellent. However, in the event of
our breach of the patent license agreement for any reason, and our inability to cure such breach within any cure period or obtain a waiver from UT, we
could lose the patent license agreement, which would result in our loss of all rights to the TFF technology.

Our business may be adversely affected by the recent COVID-19 outbreak. In December 2019, a novel strain of coronavirus, COVID-19, was
reported to have surfaced in Wuhan, China. In January 2020, this coronavirus spread to other countries, including the United States, and efforts to contain
the  spread  of  COVID-19  have  intensified.  At  this  time,  the  United  States  and  certain  other  countries  are  the  subject  of  lock-downs  and  self-isolation
procedures, which have significantly limited business operations and restricted internal and external meetings. We had expected to commence Phase 1
clinical trials our TFF formulation of Tacrolimus, or TFF Tac-Lac, in Australia in the first quarter of 2020, and on March 13, 2020 we had received the
approval  of  the  Australian  Human  Research  Ethics  Committee  to  commence  Phase  1  trials,  however  later  in  March  2020  our  contract  research
organization in Australia informed us that because of the spread of the COVID-19 virus in Australia, there would be a delay in initiating the trial. One
contributing factor is that Tacrolimus is an immunosuppressant drug and, given the threat of the COVID-19 virus, concern exists that even though we
would be dosing healthy volunteers the inhalation of an immunosuppressant could increase the risk of severe complications if a volunteer was to contract
COVID-19. As of the date of this report, we are unable to predict the length of the delay in the commencement of Phase 1 clinical trials for our TFF Tac-
Lac. Further, the outbreak and any preventative or protective actions that we or our customers may take in respect of COVID-19 may result in a period of
disruption  to  other  work  in  progress.  Our  customers’  businesses  could  be  disrupted,  and  our  future  costs  and  potential  revenues  and  technology
evaluations could be negatively affected. Any resulting financial impact cannot be reasonably estimated at this time but may materially affect our business
and financial condition. The extent to which COVID-19 impacts our results will depend on future developments, which are highly uncertain and cannot be
predicted, including new information which may emerge concerning the severity of COVID-19 and the actions to contain COVID-19 or treat its impact,
among others.

We currently have no sales and marketing organization. If we are unable to establish satisfactory sales and marketing capabilities or secure a
third-party sales and marketing relationship, we may not be able to successfully commercialize any of our product candidates. At present, we have no
sales or marketing personnel. Upon and subject to initial receipt of the requisite regulatory approvals for one or more of our drug products, we intend to
commercialize  our  drug  products  through  a  combination  of  our  internal  direct  sales  force,  third-party  marketing  and  distribution  relationships.  In  some
cases, such as involving the development of combination drugs or the development of dry powder formulations of patented drugs, we intend to pursue the
licensing of our TFF technology or enter into a joint development arrangement. If we are not successful in recruiting sales and marketing personnel and
building a sales and marketing infrastructure or entering into appropriate collaboration arrangements with third parties, we will have difficulty successfully
commercializing our product candidates, which would adversely affect our business, operating results and financial condition.

20

 
 
 
 
 
 
 
Even  if  we  enter  into  third-party  marketing  and  distribution  arrangements,  we  may  have  limited  or  no  control  over  the  sales,  marketing  and
distribution  activities  of  these  third  parties.  Our  future  revenues  may  depend  heavily  on  the  success  of  the  efforts  of  these  third  parties.  In  terms  of
establishing a sales and marketing infrastructure, we will have to compete with established and well-funded pharmaceutical and biotechnology companies
to  recruit,  hire,  train  and  retain  sales  and  marketing  personnel.  Factors  that  may  inhibit  our  efforts  to  build  an  internal  sales  organization  or  enter  into
collaboration arrangements with third parties include:

● our inability to recruit and retain adequate numbers of effective sales and marketing personnel;

● the inability of sales personnel to obtain access to or persuade adequate numbers of physicians to prescribe any of our product candidates;

● the lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies

with more extensive product lines; and

● unforeseen costs and expenses associated with creating an internal sales and marketing organization.

We will be completely dependent on third parties to manufacture our product candidates, and the commercialization of our product candidates
could  be  halted,  delayed  or  made  less  profitable  if  those  third  parties  fail  to  obtain  manufacturing  approval  from  the  FDA  or  comparable  foreign
regulatory authorities fail to provide us with sufficient quantities of our product candidates or fail to do so at acceptable quality levels or prices. We do
not  currently  have,  nor  do  we  plan  to  acquire,  the  capability  or  infrastructure  to  manufacture  our  drug  candidates  for  use  in  our  clinical  trials  or  for
commercial sales, if any. As a result, we will be obligated to rely on contract manufacturers, if and when any of our product candidates are approved for
commercialization. We have entered into short-term contract manufacturing agreements with IriSys, Inc. and CoreRx, Inc. for their provision of certain
product testing, development and clinical manufacturing services for our TFF Vori and TFF Tac-Lac product candidates, respectively, and we are currently
in discussion with several contract manufacturers for the commercial supply of any drug candidates we are able to bring to market. However, we have not
entered  into  agreements  with  any  contract  manufacturers  for  commercial  supply  and  may  not  be  able  to  engage  contract  manufacturers  for  commercial
supply of any of our product candidates on favorable terms to us, or at all, should the need arise.

The  facilities  used  by  our  current  and  future  contract  manufacturers  to  manufacture  our  product  candidates  must  be  approved  by  the  FDA  or
comparable foreign regulatory authorities. Such approvals are subject to inspections that will be conducted after we submit a New Drug Application, or
NDA,  or  Biologics  License  Application,  or  BLA,  to  the  FDA  or  their  equivalents  to  other  relevant  regulatory  authorities.  We  will  not  control  the
manufacturing process of our product candidates, and will be completely dependent on our contract manufacturing partners for compliance with Current
Good Manufacturing Practices, or cGMPs, for manufacture of both active drug substances and finished drug products. These cGMP regulations cover all
aspects  of  the  manufacturing,  testing,  quality  control,  storage,  distribution  and  record  keeping  relating  to  our  product  candidates.  If  our  contract
manufacturers do not successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or others, we
will not be able to secure or maintain regulatory approval for product made at their manufacturing facilities. If the FDA or a comparable foreign regulatory
authority does not approve these facilities for the manufacture of our product candidates or if it withdraws any such approval in the future, we may need to
find alternative manufacturing facilities, which would significantly impact our ability to develop, manufacture, obtain regulatory approval for or market our
product  candidates,  if  approved.  Likewise,  we  could  be  negatively  impacted  if  any  of  our  contract  manufacturers  elect  to  discontinue  their  business
relationship with us.

Our contract manufacturers will be subject to ongoing periodic unannounced inspections by the FDA and corresponding state and foreign agencies
for  compliance  with  cGMPs  and  similar  regulatory  requirements.  We  will  not  have  control  over  our  contract  manufacturers’  compliance  with  these
regulations and standards. Failure by any of our contract manufacturers to comply with applicable regulations could result in sanctions being imposed on
us, including fines, injunctions, civil penalties, failure to grant approval to market any of our product candidates, delays, suspensions or withdrawals of
approvals, inability to supply product, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect our business.
In addition, we will not have control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance and qualified
personnel.  Failure  by  our  contract  manufacturers  to  comply  with  or  maintain  any  of  these  standards  could  adversely  affect  our  ability  to  develop,
manufacture, obtain regulatory approval for or market any of our product candidates, if approved.

21

 
 
 
 
 
 
 
 
 
 
If, for any reason, these third parties are unable or unwilling to perform we may not be able to locate alternative manufacturers or formulators or
enter  into  favorable  agreements  with  them  and  we  cannot  be  certain  that  any  such  third  parties  will  have  the  manufacturing  capacity  to  meet  future
requirements.  If  these  manufacturers  or  any  alternate  manufacturer  of  finished  drug  product  experiences  any  significant  difficulties  in  its  respective
manufacturing processes for our active pharmaceutical ingredients, or APIs, or finished products or should cease doing business with us for any reason, we
could experience significant interruptions in the supply of any of our product candidates or may not be able to create a supply of our product candidates at
all.  Were  we  to  encounter  manufacturing  difficulties,  our  ability  to  produce  a  sufficient  supply  of  any  of  our  product  candidates  might  be  negatively
affected. Our inability to coordinate the efforts of our third-party manufacturing partners, or the lack of capacity available at our third-party manufacturing
partners, could impair our ability to supply any of our product candidates at required levels. Because of the significant regulatory requirements that we
would need to satisfy in order to qualify a new bulk drug substance or finished product manufacturer, if we face these or other difficulties with our then
current manufacturing partners, we could experience significant interruptions in the supply of any of our product candidates if we decided to transfer the
manufacture of any of our product candidates to one or more alternative manufacturers in an effort to deal with such difficulties.

Any manufacturing problem or the loss of a contract manufacturer could be disruptive to our operations and result in development delays and lost
sales. Additionally, we will rely on third parties to supply the raw materials needed to manufacture our product candidates. Any such reliance on suppliers
may  involve  several  risks,  including  a  potential  inability  to  obtain  critical  materials  and  reduced  control  over  production  costs,  delivery  schedules,
reliability and quality. Any unanticipated disruption to the operation of one of our contract manufacturers caused by problems with suppliers could delay
shipment of any of our product candidates, increase our cost of goods sold and result in lost sales.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our
product candidates. We will face a potential risk of product liability as a result of the clinical testing of our product candidates and will face an even greater
risk of such liability if we commercialize any of our product candidates. For example, we may be sued if any product we develop, including any of our
product candidates, or any materials that we use in our product candidates allegedly causes injury or is found to be otherwise unsuitable during product
testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure
to warn of dangers inherent in the product, negligence, strict liability and a breach of warranties. In the U.S., claims could also be asserted against us under
state  consumer  protection  acts.  If  we  cannot  successfully  defend  ourselves  against  product  liability  claims,  we  may  incur  substantial  liabilities  or  be
required to limit commercialization of our product candidates. Even successful defense of these claims would require us to employ significant financial and
management resources. Regardless of the merits or eventual outcome, liability claims may result in:

● decreased demand for any of our product candidates or any future products that we may develop;

● injury to our reputation;

● failure to obtain regulatory approval for our product candidates;

● withdrawal of participants in our clinical trials;

● costs associated with our defense of the related litigation;

● a diversion of our management’s time and our resources;

22

 
 
 
 
 
 
 
 
 
 
 
● substantial monetary awards to trial participants or patients;

● product recalls, withdrawals or labeling, marketing or promotional restrictions;

● the inability to commercialize some or all of our product candidates; and

● a decline in the value of our stock.

As of the date of this report, we have procured insurance coverage for our human clinical trials, which we consider adequate for our current level
of clinical testing and development, however we do not carry product liability insurance. We intend to obtain product liability insurance at the time we
commence commercial sale of our initial product. Our inability to obtain and retain sufficient product liability insurance at an acceptable cost to protect
against potential product liability claims could prevent or inhibit the commercialization of products we develop. Although we will endeavor to obtain and
maintain such insurance in coverage amounts we deem adequate, any claim that may be brought against us could result in a court judgment or settlement in
an amount that is not covered, in whole or in part, by our insurance or that is in excess of the limits of our insurance coverage. Our insurance policies
would also have various exclusions, and we may be subject to a product liability claim for which we have no coverage. As a result, we may have to pay any
amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not
have, or be able to obtain, sufficient capital to pay such amounts.

Our business operations could suffer in the event of information technology systems’ failures or security breaches. While we believe that we
have  implemented  adequate  security  measures  within  our  internal  information  technology  and  networking  systems,  our  information  technology  systems
may be subject to security breaches, damages from computer viruses, natural disasters, terrorism, and telecommunication failures. Any system failure or
security breach could cause interruptions in our operations in addition to the possibility of losing proprietary information and trade secrets. To the extent
that any disruption or security breach results in inappropriate disclosure of our confidential information, our competitive position may be adversely affected
and we may incur liability or additional costs to remedy the damages caused by these disruptions or security breaches.

Sales of counterfeit versions of our product candidates, as well as unauthorized sales of our product candidates, may have adverse effects on
our revenues, business, results of operations and damage our brand and reputation. Our product candidates may become subject to competition from
counterfeit  pharmaceutical  products,  which  are  pharmaceutical  products  sold  under  the  same  or  very  similar  brand  names  and/or  having  a  similar
appearance to genuine products, but which are sold without proper licenses or approvals. Such products divert sales from genuine products, often are of
lower  cost  and  quality  (having  different  ingredients  or  formulations,  for  example),  and  have  the  potential  to  damage  the  reputation  for  quality  and
effectiveness of the genuine product. Obtaining regulatory approval for our product candidates is a complex and lengthy process. If during the period while
the regulatory approval is pending illegal sales of counterfeit products begin, consumers may buy such counterfeit products, which could have an adverse
impact on our revenues, business and results of operations. In addition, if illegal sales of counterfeits result in adverse side effects to consumers, we may be
associated with any negative publicity resulting from such incidents. Although pharmaceutical regulation, control and enforcement systems throughout the
world have been increasingly active in policing counterfeit pharmaceuticals, we may not be able to prevent third parties from manufacturing, selling or
purporting to sell counterfeit products competing with our product candidates. Such sales may also be occurring without our knowledge. The existence and
any  increase  in  production  or  sales  of  counterfeit  products  or  unauthorized  sales  could  negatively  impact  our  revenues,  brand  reputation,  business  and
results of operations.

Risks Related to Product Regulation

Our success is entirely dependent on our ability to obtain the marketing approval for our product candidates by the FDA and the regulatory
authorities in foreign jurisdictions in which we intend to market our product candidates, of which there can be no assurance. We are not permitted to
market our product candidates as prescription pharmaceutical products in the United States until we receive approval of an NDA from the FDA, or in any
foreign countries until we receive the requisite approval from such countries. In the United States, the FDA generally requires the completion of clinical
trials of each drug to establish its safety and efficacy and extensive pharmaceutical development to ensure its quality before an NDA is approved. Of the
large number of drugs in development, only a small percentage result in the submission of an NDA to the FDA and even fewer are eventually approved for
commercialization. As of the date of this report, we have not submitted an NDA to the FDA or comparable applications to other regulatory authorities for
any of our product candidates.

Because our initial dry powder drug candidates, TFF Vori and TFF Tac-Lac, will be established drugs that are off-patent, we believe that our initial
drug  product  candidates  will  qualify  for  FDA  approval  through  the  FDA’s  505(b)(2)  regulatory  pathway  and  in  corresponding  regulatory  paths  in  other
foreign jurisdictions. The 505(b)(2) pathway sometimes does not require clinical trials other than a bioequivalence trial; however, to the extent we claim
that  our  drug  product  candidates  target  a  new  indication  or  offer  improved  safety  compared  to  the  existing  approved  products,  and  it  is  our  present
expectation that we will do so in many cases, it is likely that we will be required to conduct additional clinical trials in order to obtain marketing approval.
For example, based on separate pre-IND meetings with the FDA concerning TFF Vori and TFF Tac-Lac, we believe we will need to conduct Phase I and
Phase II studies prior to filing for marketing approval for TFF Vori and Phase I and Phase IIb/IIIa studies prior to filing for marketing approval for TFF
Tac-Lac. However, there can be no assurance that the FDA will not ask for additional clinical data for either TFF Vori or TFF Tac-Lac.

Our  business  model  is  to  pursue  the  development  of  off-patent  drugs  for  which  we  would  directly  pursue  the  development  of  a  dry  powder
formulation through the FDA’s 505(b)(2) regulatory pathway; however, not all of our product candidates will target off-patent drugs and, at least in the case
of a dry powder formulation of CBD, our product candidate may not be a drug. We do not expect any dry powder formulation of a CBD drug product to be
off-patent and our proposed dry powder formulation of aluminum salt vaccines may not be off-patent. We also expect that our dry powder formulation of a
CBD  drug  product  will  likely  require  a  full  NDA  through  the  FDA’s  505(b)(1)  regulatory  pathway;  however,  a  non-pharmaceutical  CBD  dry  powder
formulation  may  not  require  FDA  approval.  We  expect  that  our  dry  powder  formulation  of  aluminum  salt  vaccines  will  require  a  biological  license
application, or BLA, which is very similar to a full NDA through the FDA’s 505(b)(1) regulatory pathway. 

Our success depends on our receipt of the regulatory approvals described above, and the issuance of such regulatory approvals is uncertain and

subject to a number of risks, including the following:

● the results of toxicology studies may not support the filing of an IND for our product candidates;

● the FDA or comparable foreign regulatory authorities or Institutional Review Boards, or IRB, may disagree with the design or implementation

of our clinical trials;

● we may not be able to provide acceptable evidence of our product candidates’ safety and efficacy;

● the results of our clinical trials may not be satisfactory or may not meet the level of statistical or clinical significance required by the FDA,
European Medicines Agency, or EMA, or other regulatory agencies for us to receive marketing approval for any of our product candidates;

● the dosing of our product candidates in a particular clinical trial may not be at an optimal level;

● patients in our clinical trials may suffer adverse effects for reasons that may or may not be related to our product candidates;

24

 
 
 
 
 
 
 
 
 
 
 
 
 
● the  data  collected  from  clinical  trials  may  not  be  sufficient  to  support  the  submission  of  an  NDA,  BLA  or  other  submission  or  to  obtain

regulatory approval in the United States or elsewhere;

● the  FDA  or  comparable  foreign  regulatory  authorities  may  fail  to  approve  the  manufacturing  processes  or  facilities  of  third-party

manufacturers with which we contract for clinical and commercial supplies; and

● the approval policies or regulations of the FDA or comparable foreign regulatory authorities may significantly change in a manner rendering

our clinical data insufficient for approval of our product candidates.

The process of obtaining regulatory approvals is expensive, often takes many years, if approval is obtained at all, and can vary substantially based
upon, among other things, the type, complexity and novelty of the product candidates involved, the jurisdiction in which regulatory approval is sought and
the substantial discretion of the regulatory authorities. Changes in regulatory approval policies during the development period, changes in or the enactment
of additional statutes or regulations, or changes in regulatory review for a submitted product application may cause delays in the approval or rejection of an
application.  Regulatory  approval  obtained  in  one  jurisdiction  does  not  necessarily  mean  that  a  product  candidate  will  receive  regulatory  approval  in  all
jurisdictions in which we may seek approval, but the failure to obtain approval in one jurisdiction may negatively impact our ability to seek approval in a
different  jurisdiction.  Failure  to  obtain  regulatory  approval  for  our  product  candidates  for  the  foregoing,  or  any  other  reasons,  will  prevent  us  from
commercializing our product candidates, and our ability to generate revenue will be materially impaired.

Clinical  testing  is  expensive,  is  difficult  to  design  and  implement,  can  take  many  years  to  complete  and  is  uncertain  as  to  outcome.  Our
business model depends entirely on the successful development, regulatory approval and commercialization of our product candidates, which may never
occur. In November 2019, we initiated Phase I human clinical trials for our TFF Vori product candidate and we had a pre-IND meeting for TFF Tac-Lac in
September 2019. We had intended to commence Phase 1 clinical trials for TFF Tac-Lac in the first quarter of 2020, however the commencement of clinical
trials has been delayed due to the COVID-19 pandemic. As of the date of this report, we are unable to predict the length of the delay in the commencement
of Phase 1 clinical trials for our TFF Tac-Lac. Further, as of the date of this report, we have not otherwise progressed any of our product candidates beyond
performance  characterization  and  animal  testing.  We  may  not  be  successful  in  obtaining  approval  from  the  FDA  or  comparable  foreign  regulatory
authorities to start clinical trials for any other of our product candidates. If we do not obtain such approvals as presently planned, the time in which we
expect to commence clinical programs for any product candidate will be extended and such extension will increase our expenses, delay our potential receipt
of any revenues, and increase our need for additional capital. Moreover, there is no guarantee that we will receive approval to commence human clinical
trials or, if we do receive approval, that our clinical trials will be successful or that we will continue clinical development in support of an approval from the
FDA or comparable foreign regulatory authorities for any indication. We note that most product candidates never reach the clinical development stage and
even  those  that  do  commence  clinical  development  have  only  a  small  chance  of  successfully  completing  clinical  development  and  gaining  regulatory
approval. Success in early phases of pre-clinical and clinical trials does not ensure that later clinical trials will be successful, and interim results of a clinical
trial do not necessarily predict final results. A failure of one or more of our clinical trials can occur at any stage of testing. We may experience numerous
unforeseen events during, or as a result of, the clinical trial process that could delay or prevent our ability to receive regulatory approval or commercialize
our product candidates. Therefore, our business currently depends entirely on the successful development, regulatory approval and commercialization of
our product candidates, which may never occur.

Even if we receive regulatory approval for any of our product candidates, we may not be able to successfully commercialize the product and
the  revenue  that  we  generate  from  its  sales,  if  any,  may  be  limited.  If  approved  for  marketing,  the  commercial  success  of  our  product  candidates  will
depend upon each product’s acceptance by the medical community, including physicians, patients and health care payors. The degree of market acceptance
for any of our product candidates will depend on a number of factors, including:

● demonstration of clinical safety and efficacy;

● relative convenience, dosing burden and ease of administration;

25

 
 
 
 
 
 
 
 
 
 
● the prevalence and severity of any adverse effects;

● the willingness of physicians to prescribe our product candidates, and the target patient population to try new therapies;

● efficacy of our product candidates compared to competing products;

● the introduction of any new products that may in the future become available targeting indications for which our product candidates may be

approved;

● new procedures or therapies that may reduce the incidences of any of the indications in which our product candidates may show utility;

● pricing and cost-effectiveness;

● the inclusion or omission of our product candidates in applicable therapeutic and vaccine guidelines;

● the effectiveness of our own or any future collaborators’ sales and marketing strategies;

● limitations or warnings contained in approved labeling from regulatory authorities;

● our  ability  to  obtain  and  maintain  sufficient  third-party  coverage  or  reimbursement  from  government  health  care  programs,  including
Medicare and Medicaid, private health insurers and other third-party payors or to receive the necessary pricing approvals from government
bodies regulating the pricing and usage of therapeutics; and

● the willingness of patients to pay out-of-pocket in the absence of third-party coverage or reimbursement or government pricing approvals.

If any of our product candidates are approved, but do not achieve an adequate level of acceptance by physicians, health care payors, and patients,
we may not generate sufficient revenue and we may not be able to achieve or sustain profitability. Our efforts to educate the medical community and third-
party payors on the benefits of our product candidates may require significant resources and may never be successful.

In addition, even if we obtain regulatory approvals, the timing or scope of any approvals may prohibit or reduce our ability to commercialize our
product  candidates  successfully.  For  example,  if  the  approval  process  takes  too  long,  we  may  miss  market  opportunities  and  give  other  companies  the
ability  to  develop  competing  products  or  establish  market  dominance.  Any  regulatory  approval  we  ultimately  obtain  may  be  limited  or  subject  to
restrictions or post-approval commitments that render our product candidates not commercially viable. For example, regulatory authorities may approve
any of our product candidates for fewer or more limited indications than we request, may not approve the price we intend to charge for any of our product
candidates, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve any of our product candidates with a
label  that  does  not  include  the  labeling  claims  necessary  or  desirable  for  the  successful  commercialization  of  that  indication.  Further,  the  FDA  or
comparable  foreign  regulatory  authorities  may  place  conditions  on  approvals  or  require  risk  management  plans  or  a  Risk  Evaluation  and  Mitigation
Strategy, or REMS, to assure the safe use of the drug. Moreover, product approvals may be withdrawn for non-compliance with regulatory standards or if
problems occur following the initial marketing of the product. Any of the foregoing scenarios could materially harm the commercial success of our product
candidates.

Even if we obtain marketing approval for any of our product candidates, we will be subject to ongoing obligations and continued regulatory
review, which may result in significant additional expense. Additionally, our product candidates could be subject to labeling and other restrictions and
withdrawal from the market and we may be subject to penalties if we fail to comply with regulatory requirements or if we experience unanticipated
problems  with  our  product  candidates.  Even  if  we  obtain  regulatory  approval  for  any  of  our  product  candidates  for  an  indication,  the  FDA  or  foreign
equivalent may still impose significant restrictions on their indicated uses or marketing or the conditions of approval, or impose ongoing requirements for
potentially costly and time-consuming post-approval studies, including Phase 4 clinical trials, and post-market surveillance to monitor safety and efficacy.
Our  product  candidates  will  also  be  subject  to  ongoing  regulatory  requirements  governing  the  manufacturing,  labeling,  packaging,  storage,  distribution,
safety surveillance, advertising, promotion, recordkeeping and reporting of adverse events and other post-market information. These requirements include
registration  with  the  FDA,  as  well  as  continued  compliance  with  current  Good  Clinical  Practices  regulations,  or  cGCPs,  for  any  clinical  trials  that  we
conduct post-approval. In addition, manufacturers of drug products and their facilities are subject to continual review and periodic inspections by the FDA
and  other  regulatory  authorities  for  compliance  with  current  cGMPs,  requirements  relating  to  quality  control,  quality  assurance  and  corresponding
maintenance of records and documents.

26

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The FDA has the authority to require a REMS as part of an NDA or after approval, which may impose further requirements or restrictions on the
distribution  or  use  of  an  approved  drug,  such  as  limiting  prescribing  to  certain  physicians  or  medical  centers  that  have  undergone  specialized  training,
limiting treatment to patients who meet certain safe-use criteria or requiring patient testing, monitoring and/or enrollment in a registry.

With respect to sales and marketing activities related to our product candidates, advertising and promotional materials must comply with FDA
rules in addition to other applicable federal, state and local laws in the United States and similar legal requirements in other countries. In the United States,
the  distribution  of  product  samples  to  physicians  must  comply  with  the  requirements  of  the  U.S.  Prescription  Drug  Marketing  Act.  Application  holders
must obtain FDA approval for product and manufacturing changes, depending on the nature of the change. We may also be subject, directly or indirectly
through our customers and partners, to various fraud and abuse laws, including, without limitation, the U.S. Anti-Kickback Statute, U.S. False Claims Act,
and similar state laws, which impact, among other things, our proposed sales, marketing, and scientific/educational grant programs. If we participate in the
U.S. Medicaid Drug Rebate Program, the Federal Supply Schedule of the U.S. Department of Veterans Affairs, or other government drug programs, we
will  be  subject  to  complex  laws  and  regulations  regarding  reporting  and  payment  obligations.  All  of  these  activities  are  also  potentially  subject  to  U.S.
federal and state consumer protection and unfair competition laws. Similar requirements exist in many of these areas in other countries.

In addition, if any of our product candidates are approved for a particular indication, our product labeling, advertising and promotion would be
subject  to  regulatory  requirements  and  continuing  regulatory  review.  The  FDA  strictly  regulates  the  promotional  claims  that  may  be  made  about
prescription  products.  In  particular,  a  product  may  not  be  promoted  for  uses  that  are  not  approved  by  the  FDA  as  reflected  in  the  product’s  approved
labeling.  If  we  receive  marketing  approval  for  our  product  candidates,  physicians  may  nevertheless  legally  prescribe  our  products  to  their  patients  in  a
manner that is inconsistent with the approved label. If we are found to have promoted such off-label uses, we may become subject to significant liability
and government fines. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company
that is found to have improperly promoted off-label uses may be subject to significant sanctions. The federal government has levied large civil and criminal
fines  against  companies  for  alleged  improper  promotion  and  has  enjoined  several  companies  from  engaging  in  off-label  promotion.  The  FDA  has  also
requested that companies enter into consent decrees of permanent injunctions under which specified promotional conduct is changed or curtailed.

If we or a regulatory agency discover previously unknown problems with a product candidate, such as adverse events of unanticipated severity or
frequency,  problems  with  the  facility  where  the  product  is  manufactured,  or  we  or  our  manufacturers  fail  to  comply  with  applicable  regulatory
requirements, we may be subject to the following administrative or judicial sanctions:

● restrictions on the marketing or manufacturing of the product, withdrawal of the product from the market, or voluntary or mandatory product

recalls;

● issuance of warning letters or untitled letters;

● clinical holds;

● injunctions or the imposition of civil or criminal penalties or monetary fines;

27

 
 
 
 
 
 
 
 
 
 
● suspension or withdrawal of regulatory approval;

● suspension of any ongoing clinical trials;

● refusal to approve pending applications or supplements to approved applications filed by us, or suspension or revocation of product license

approvals;

● suspension or imposition of restrictions on operations, including costly new manufacturing requirements; or

● product seizure or detention or refusal to permit the import or export of product.

The occurrence of any event or penalty described above may inhibit our ability to commercialize our product candidates and generate revenue.

Adverse regulatory action, whether pre- or post-approval, can also potentially lead to product liability claims and increase our product liability exposure.

Obtaining  and  maintaining  regulatory  approval  of  our  product  candidates  in  one  jurisdiction  does  not  mean  that  we  will  be  successful  in
obtaining regulatory approval of our product candidates in other jurisdictions. Obtaining and maintaining regulatory approval of our product candidates
in  one  jurisdiction  does  not  guarantee  that  we  will  be  able  to  obtain  or  maintain  regulatory  approval  in  any  other  jurisdiction,  but  a  failure  or  delay  in
obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory approval process in others. For example, even if the FDA
grants  marketing  approval  of  a  product  candidate,  comparable  regulatory  authorities  in  foreign  jurisdictions  must  also  approve  the  manufacturing,
marketing  and  promotion  of  the  product  candidate  in  those  countries.  Approval  procedures  vary  among  jurisdictions  and  can  involve  requirements  and
administrative  review  periods  different  from  those  in  the  United  States,  including  additional  preclinical  studies  or  clinical  trials,  as  clinical  studies
conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the United States, a product
candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we intend to charge for
our products is also subject to approval.

Obtaining  foreign  regulatory  approvals  and  compliance  with  foreign  regulatory  requirements  could  result  in  significant  delays,  difficulties  and
costs for us and could delay or prevent the introduction of our product candidates in certain countries. If we fail to comply with the regulatory requirements
in  international  markets  and/  or  to  receive  applicable  marketing  approvals,  our  target  market  will  be  reduced  and  our  ability  to  realize  the  full  market
potential of our product candidates will be harmed.

Even  though  we  may  apply  for  orphan  drug  designation  for  a  product  candidate,  we  may  not  be  able  to  obtain  orphan  drug  marketing
exclusivity. We believe that in some cases our dry powder drug products may qualify for the FDA’s orphan drug status. There is no guarantee that the FDA
will  grant  any  future  application  for  orphan  drug  designation  for  any  of  our  product  candidates,  which  would  make  us  ineligible  for  the  additional
exclusivity and other benefits of orphan drug designation.

Under the Orphan Drug Act, the FDA may grant orphan drug designation to a drug intended to treat a rare disease or condition, which is generally
a disease or condition that affects fewer than 200,000 individuals in the United States and for which there is no reasonable expectation that the cost of
developing and making a drug available in the United States for this type of disease or condition will be recovered from sales of the product. Orphan drug
designation  must  be  requested  before  submitting  an  NDA.  After  the  FDA  grants  orphan  drug  designation,  the  identity  of  the  therapeutic  agent  and  its
potential orphan use are disclosed publicly by the FDA. Orphan product designation does not convey any advantage in or shorten the duration of regulatory
review and approval process. In addition to the potential period of exclusivity, orphan designation makes a company eligible for grant funding of up to
$400,000 per year for four years to defray costs of clinical trial expenses, tax credits for clinical research expenses and potential exemption from the FDA
application user fee.

28

 
 
 
 
 
 
 
 
 
 
 
 
If  a  product  that  has  orphan  designation  subsequently  receives  the  first  FDA  approval  for  the  disease  or  condition  for  which  it  has  such
designation, the product is entitled to orphan drug exclusivity, which means the FDA may not approve any other applications to market the same drug for
the same indication for seven years, except in limited circumstances, such as (i) the drug’s orphan designation is revoked; (ii) its marketing approval is
withdrawn; (iii) the orphan exclusivity holder consents to the approval of another applicant’s product; (iv) the orphan exclusivity holder is unable to assure
the availability of a sufficient quantity of drug; or (v) a showing of clinical superiority to the product with orphan exclusivity by a competitor product. If a
drug designated as an orphan product receives marketing approval for an indication broader than what is designated, it may not be entitled to orphan drug
exclusivity. There can be no assurance that we will receive orphan drug designation for any of our product candidates in the indications for which we think
they might qualify, if we elect to seek such applications.

Current  and  future  legislation  may  increase  the  difficulty  and  cost  for  us  to  obtain  marketing  approval  of  and  commercialize  our  product
candidates and affect the prices we may obtain. In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory
changes  and  proposed  changes  regarding  the  healthcare  system  that  could  prevent  or  delay  marketing  approval  for  our  product  candidates,  restrict  or
regulate post-approval activities and affect our ability to profitably sell our product candidates. Legislative and regulatory proposals have been made to
expand post-approval requirements and restrict sales and promotional activities for pharmaceutical products. We do not know whether additional legislative
changes will be enacted, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing
approvals of our product candidates, if any, may be. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly
delay or prevent marketing approval, as well as subject us to more stringent product labeling and post-marketing testing and other requirements.

In the United States, the Medicare Modernization Act, or MMA, changed the way Medicare covers and pays for pharmaceutical products. The
legislation expanded Medicare coverage for drug purchases by the elderly and introduced a new reimbursement methodology based on average sales prices
for drugs. In addition, this legislation authorized Medicare Part D prescription drug plans to use formularies where they can limit the number of drugs that
will be covered in any therapeutic class. As a result of this legislation and the expansion of federal coverage of drug products, we expect that there will be
additional pressure to contain and reduce costs. These cost reduction initiatives and other provisions of this legislation could decrease the coverage and
price  that  we  receive  for  our  product  candidates  and  could  seriously  harm  our  business.  While  the  MMA  applies  only  to  drug  benefits  for  Medicare
beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates, and any reduction in
reimbursement that results from the MMA may result in a similar reduction in payments from private payors.

The  Patient  Protection  and  Affordable  Care Act,  as  amended  by  the  Health  Care  and  Education  Affordability  Reconciliation Act  of  2010  or,
collectively, the Health Care Reform Law, is a sweeping law intended to broaden access to health insurance, reduce or constrain the growth of healthcare
spending, enhance remedies against fraud and abuse, add new transparency requirements for healthcare and health insurance industries, impose new taxes
and fees on the health industry and impose additional health policy reforms. The Health Care Reform Law revised the definition of “average manufacturer
price” for reporting purposes, which could increase the amount of Medicaid drug rebates to states. Further, the law imposed a significant annual fee on
companies that manufacture or import branded prescription drug products.

The Health Care Reform Law remains subject to legislative efforts to repeal, modify or delay the implementation of the law. If the Health Care
Reform Law is repealed or modified, or if implementation of certain aspects of the Health Care Reform Law are delayed, such repeal, modification or delay
may materially adversely impact our business, strategies, prospects, operating results or financial condition. We are unable to predict the full impact of any
repeal, modification or delay in the implementation of the Health Care Reform Law on us at this time. Due to the substantial regulatory changes that will
need  to  be  implemented  by  Centers  for  Medicare  &  Medicaid  Services,  or  CMS,  and  others,  and  the  numerous  processes  required  to  implement  these
reforms, we cannot predict which healthcare initiatives will be implemented at the federal or state level, the timing of any such reforms, or the effect such
reforms or any other future legislation or regulation will have on our business.

29

 
 
 
 
 
 
 
In addition, other legislative changes have been proposed and adopted in the United States since the Health Care Reform Law was enacted. We
expect  that  additional  federal  healthcare  reform  measures  will  be  adopted  in  the  future,  any  of  which  could  limit  the  amounts  that  federal  and  state
governments will pay for healthcare products and services, and in turn could significantly reduce the projected value of certain development projects and
reduce or eliminate our profitability.

Any termination or suspension of, or delays in the commencement or completion of, any necessary studies of any of our product candidates for
any indications could result in increased costs to us, delay or limit our ability to generate revenue and adversely affect our commercial prospects. The
commencement and completion of clinical studies can be delayed for a number of reasons, including delays related to:

● the FDA or a comparable foreign regulatory authority failing to grant permission to proceed and placing the clinical study on hold;

● subjects for clinical testing failing to enroll or remain enrolled in our trials at the rate we expect;

● a facility manufacturing any of our product candidates being ordered by the FDA or other government or regulatory authorities to temporarily
or  permanently  shut  down  due  to  violations  of  cGMP  requirements  or  other  applicable  requirements,  or  cross-contaminations  of  product
candidates in the manufacturing process;

● any changes to our manufacturing process that may be necessary or desired;

● subjects  choosing  an  alternative  treatment  for  the  indications  for  which  we  are  developing  our  product  candidates,  or  participating  in

competing clinical studies;

● subjects experiencing severe or unexpected drug-related adverse effects;

● reports from clinical testing on similar technologies and products raising safety and/or efficacy concerns;

● third-party clinical investigators losing their license or permits necessary to perform our clinical trials, not performing our clinical trials on our
anticipated  schedule  or  employing  methods  consistent  with  the  clinical  trial  protocol,  cGMP  requirements,  or  other  third  parties  not
performing data collection and analysis in a timely or accurate manner;

● inspections of clinical study sites by the FDA, comparable foreign regulatory authorities, or IRBs finding regulatory violations that require us
to undertake corrective action, result in suspension or termination of one or more sites or the imposition of a clinical hold on the entire study,
or that prohibit us from using some or all of the data in support of our marketing applications;

● third-party contractors becoming debarred or suspended or otherwise penalized by the FDA or other government or regulatory authorities for
violations of regulatory requirements, in which case we may need to find a substitute contractor, and we may not be able to use some or any
of the data produced by such contractors in support of our marketing applications;

● one  or  more  IRBs  refusing  to  approve,  suspending  or  terminating  the  study  at  an  investigational  site,  precluding  enrollment  of  additional
subjects, or withdrawing its approval of the trial; reaching agreement on acceptable terms with prospective contract research organizations, or
CROs, and clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs
and trial sites;

● deviations of the clinical sites from trial protocols or dropping out of a trial;

● adding new clinical trial sites;

30

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● the inability of the CRO to execute any clinical trials for any reason; and

● government or regulatory delays or “clinical holds” requiring suspension or termination of a trial.

Product development costs for any of our product candidates will increase if we have delays in testing or approval or if we need to perform more
or larger clinical studies than planned. Additionally, changes in regulatory requirements and policies may occur and we may need to amend study protocols
to reflect these changes. Amendments may require us to resubmit our study protocols to the FDA, comparable foreign regulatory authorities, and IRBs for
reexamination, which may impact the costs, timing or successful completion of that study. If we experience delays in completion of, or if we, the FDA or
other regulatory authorities, the IRB, or other reviewing entities, or any of our clinical study sites suspend or terminate any of our clinical studies of any of
our product candidates, its commercial prospects may be materially harmed and our ability to generate product revenues will be delayed. Any delays in
completing our clinical trials will increase our costs, slow down our development and approval process and jeopardize our ability to commence product
sales and generate revenues. Any of these occurrences may harm our business, financial condition and prospects significantly. In addition, many of the
factors that cause, or lead to, termination or suspension of, or a delay in the commencement or completion of, clinical studies may also ultimately lead to
the denial of regulatory approval of our product candidates. In addition, if one or more clinical studies are delayed, our competitors may be able to bring
competing products to market before we do, and the commercial viability of any of our affected product candidates could be significantly reduced.

Third-party  coverage  and  reimbursement  and  health  care  cost  containment  initiatives  and  treatment  guidelines  may  constrain  our  future
revenues.  Our  ability  to  successfully  market  our  product  candidates  will  depend  in  part  on  the  level  of  reimbursement  that  government  health
administration authorities, private health coverage insurers and other organizations provide for the cost of our product candidates and related treatments.
Countries in which any of our product candidates are sold through reimbursement schemes under national health insurance programs frequently require that
manufacturers  and  sellers  of  pharmaceutical  products  obtain  governmental  approval  of  initial  prices  and  any  subsequent  price  increases.  In  certain
countries, including the United States, government-funded and private medical care plans can exert significant indirect pressure on prices. We may not be
able  to  sell  our  product  candidates  profitably  if  adequate  prices  are  not  approved  or  coverage  and  reimbursement  is  unavailable  or  limited  in  scope.
Increasingly, third-party payors attempt to contain health care costs in ways that are likely to impact our development of products including: 

● failing to approve or challenging the prices charged for health care products;

● introducing reimportation schemes from lower priced jurisdictions;

● limiting both coverage and the amount of reimbursement for new therapeutic products;

● denying  or  limiting  coverage  for  products  that  are  approved  by  the  regulatory  agencies  but  are  considered  to  be  experimental  or

investigational by third-party payors; and

● refusing to provide coverage when an approved product is used in a way that has not received regulatory marketing approval.

Any  product  candidates  we  develop  that  incorporate  CBD  will  be  subject  to  U.S.  controlled  substance  laws  and  regulations  and  failure  to
comply  with  these  laws  and  regulations,  or  the  cost  of  compliance  with  these  laws  and  regulations,  may  adversely  affect  the  results  of  our  business
operations,  both  during  clinical  development  and  post  approval,  and  our  financial  condition.  We  believe  that  our  TFF  platform  could  be  used  to
formulate a dry powder version of cannabidiol, or CBD, and we are in the early stages of developing a dry powder form of CBD. CBD is a controlled
substance as defined in the federal Controlled Substances Act of 1970, or CSA. Controlled substances are subject to a high degree of regulation under the
CSA,  which  establishes,  among  other  things,  certain  registration,  manufacturing  quotas,  security,  recordkeeping,  reporting,  import,  export  and  other
requirements administered by the federal Drug Enforcement Agency, or DEA. The DEA classifies controlled substances into five schedules: Schedule I, II,
III, IV or V substances. Schedule I substances by definition have a high potential for abuse, have no currently “accepted medical use” in the United States,
lack  accepted  safety  for  use  under  medical  supervision,  and  may  not  be  prescribed,  marketed  or  sold  in  the  United  States.  Pharmaceutical  products
approved for use in the United States may be listed as Schedule II, III, IV or V, with Schedule II substances considered to present the highest potential for
abuse or dependence and Schedule V substances the lowest relative risk of abuse among such substances. Schedule I and II drugs are subject to the strictest
controls under the CSA, including manufacturing and procurement quotas, security requirements and criteria for importation. In addition, dispensing of
Schedule II drugs is further restricted. For example, they may not be refilled without a new prescription.

31

 
 
 
 
 
 
 
 
 
 
 
 
While  cannabis  and  certain  of  its  derivatives,  including  CBD,  are  Schedule  I  controlled  substances,  products  approved  for  medical  use  in  the
United  States  that  contain  cannabis  or  cannabis  extracts  must  be  placed  in  Schedules  II  through  V,  since  approval  by  the  FDA  satisfies  the  “accepted
medical use” requirement. In 2018, the FDA approved Epidiolex, a sesame oil oral solution of CBD, and the DEA scheduled Epidiolex to Schedule V. To
our knowledge, Epidiolex is the only CBD-based drug to have received FDA marketing approval. If we are able to develop a CBD-based dry powder drug
candidate,  and  the  FDA  provides  market  approval  for  such  drug  candidate,  of  which  there  can  be  no  assurance,  the  DEA  will  make  a  scheduling
determination and place our dry powder CBD-based drug candidate in a schedule other than Schedule I in order for it to be prescribed to patients in the
United  States.  If  we  are  able  to  develop  a  CBD-based  dry  powder  drug  candidate,  we  would  be  able  to  favorably  cite  Epidiolex  for  purposes  of  DEA
scheduling;  however,  there  can  be  no  assurance  that  any  CBD-based  drug  candidate  we  develop  will  be  listed  by  the  DEA  as  a  Schedule  V  controlled
substance. Furthermore, if the FDA, DEA or any foreign regulatory authority determines that any of our CBD-based drug candidates may have potential for
abuse, it may require us to generate more clinical data than would otherwise be required, which could increase the cost or delay the launch of such drug
candidate.

Facilities  conducting  research,  manufacturing,  distributing,  importing  or  exporting,  or  dispensing  controlled  substances  must  be  registered
(licensed) to perform these activities and have the security, control, recordkeeping, reporting and inventory mechanisms required by the DEA to prevent
drug loss and diversion. All these facilities must renew their registrations annually, except dispensing facilities, which must renew every three years. The
DEA conducts periodic inspections of certain registered establishments that handle controlled substances. Obtaining the necessary registrations may result
in delay of the importation, manufacturing or distribution of any CBD-based drug candidates we may develop. Furthermore, failure to maintain compliance
with the CSA, particularly non-compliance resulting in loss or diversion, can result in regulatory action that could have a material adverse effect on our
business, financial condition and results of operations. The DEA may seek civil penalties, refuse to renew necessary registrations, or initiate proceedings to
restrict, suspend or revoke those registrations. In certain circumstances, violations could lead to criminal proceedings.

Individual states have also established controlled substance laws and regulations. Though state-controlled substance laws often mirror federal law,
because the states are separate jurisdictions, they may separately schedule our product candidates as well. While some states automatically schedule a drug
based on federal action, other states schedule drugs through rulemaking or a legislative action. State scheduling may delay commercial sale of any product
for  which  we  obtain  federal  regulatory  approval  and  adverse  scheduling  could  have  a  material  adverse  effect  on  the  commercial  attractiveness  of  such
product. We must also obtain separate state registrations, permits or licenses in order to be able to obtain, handle, and distribute controlled substances for
clinical trials or commercial sale, and failure to meet applicable regulatory requirements could lead to enforcement and sanctions by the states in addition to
those from the DEA or otherwise arising under federal law.

The passage of the 2018 Farm Bill will impact our development of a dry powder version of CBD. The Agriculture Improvement Act of 2018, or
the 2018 Farm Bill, was signed into law on December 20, 2018. This new law excludes hemp from the definition of marijuana for purposes of the CSA,
and legalizes the cultivation and commercial sale of hemp in the United States, subject to state regulation and continuing oversight by federal regulatory
agencies. However, the 2018 Farm Bill does not legalize hemp-derived CBDs. CBDs generally remain a Schedule I controlled substance under the CSA
and the 2018 Farm Bill provides that a CBD will be removed from Schedule I status if, among other requirements, the CBD is derived from hemp produced
by a licensed grower in a manner consistent with the 2018 Farm Bill and associated federal and state regulations.

32

 
 
 
 
 
 
In  addition,  the  2018  Farm  Bill  did  not  alter  the  FDA’s  authority  to  regulate  products  containing  cannabis  or  cannabis-derived  compounds,
including  CBD,  under  the  Federal  Food,  Drug,  and  Cosmetic  Act.  Hemp  products,  including  CBDs,  that  qualify  as  drugs,  food,  dietary  supplements,
veterinary products, and cosmetics will continue to be regulated by the FDA under the applicable regulatory frameworks. Following passage of the 2018
Farm Bill, the FDA reaffirmed its enforcement authority and reiterated the requirement that a CBD product (hemp-derived or otherwise) that is marketed
with a claim of therapeutic benefit, or with any other disease claim, be approved by the FDA for its intended use before it may be introduced into interstate
commerce.  However,  we  believe  that  hemp-derived  CBD  products  that  are  not  marketed  with  a  claim  of  therapeutic  benefit,  or  with  any  other  disease
claim, may not require FDA pre-marketing approval. While we believe that recent legislation, most notably the 2018 Farm Bill, has reduced the amount of
DEA  regulation  of  CBDs,  this  is  a  rapidly  evolving  area  of  law  and  there  remains  some  uncertainty  surrounding  future  state  regulation  of  CBDs.  In
addition, as of the date of this report, the FDA has approved for marketing only one CBD-based drug product, Epidiolex, and there can be no assurance that
we will not encounter increased costs or delays in pursuing FDA market approval of a CBD-based dry powder formula, assuming we can obtain approval at
all.

Risks Relating to Our Intellectual Property Rights

We are dependent on rights to certain technologies licensed to us. We do not have complete control over these technologies and any loss of our
rights to them could prevent us from selling our product candidates. As noted above, our business model is entirely dependent on certain patent rights
licensed  to  us  by  the  University  of  Texas  at  Austin,  or  UT.  See,  “Risk  Factors  —  Risks  Relating  to  Our  Business  —  Our  business  model  is  entirely
dependent on certain patent rights licensed to us from the University of Texas at Austin, and the loss of those license rights would, in all likelihood, cause
our business, as presently contemplated, to fail.” Because we will hold those rights as a licensee, we have limited control over certain important aspects of
those patent rights. Pursuant to the patent license agreement, UT has reserved the right to control all decisions concerning the prosecution and maintenance
of  all  U.S.  and  foreign  patents,  as  well  as  all  decisions  concerning  the  enforcement  of  any  actions  against  potential  infringers  of  the  patent  rights.  We
believe that UT shares a common interest in these matters with us, and UT has agreed to consult with us on the prosecution and enforcement of possible
infringement claims as well as other matters for which UT has retained control. However, there can be no assurance that UT will agree with our views as to
how best to prosecute, maintain and defend the patent rights subject to the patent license agreement.

It is difficult and costly to protect our intellectual property rights, and we cannot ensure the protection of these rights. Our commercial success
will depend, in part, on our ability to successfully defend the patent rights subject to our patent license agreement with UT against third-party challenges
and successfully enforcing these patent rights against third party competitors. The patent positions of pharmaceutical companies can be highly uncertain
and involve complex legal, scientific and factual questions for which important legal principles remain unresolved. Changes in either the patent laws or in
interpretations  of  patent  laws  may  diminish  the  value  of  our  intellectual  property.  Accordingly,  we  cannot  predict  the  breadth  of  claims  that  may  be
allowable  or  enforceable  in  the  patent  applications  subject  to  the  UT  patent  license  agreement.  The  patents  and  patent  applications  relating  to  our  TFF
platform and related technologies may be challenged, invalidated or circumvented by third parties and might not protect us against competitors with similar
products or technologies.

The degree of future protection afforded by the patent rights licensed to us is uncertain, because legal means afford only limited protection and
may not adequately protect our rights, permit us to gain or keep our competitive advantage, or provide us with any competitive advantage at all. We cannot
be certain that any patent application owned by a third party will not have priority over patent applications in which we hold license rights or that we will
not be involved in interference, opposition or invalidity proceedings before United States or foreign patent offices.

Additionally,  if  UT  were  to  initiate  legal  proceedings  against  a  third  party  to  enforce  a  patent  covering  any  of  our  product  candidates,  the
defendant could counterclaim that such patent is invalid and/or unenforceable. In patent litigation in the United States, defendant counterclaims alleging
invalidity and/or unenforceability are commonplace. Grounds for a validity challenge include alleged failures to meet any of several statutory requirements,
including  lack  of  novelty,  obviousness  or  non-enablement.  Grounds  for  unenforceability  assertions  include  allegations  that  someone  connected  with
prosecution  of  the  patent  withheld  relevant  information  from  the  United  States  Patent  and  Trademark  Office,  or  the  U.S.  PTO,  or  made  a  misleading
statement,  during  prosecution.  Third  parties  may  also  raise  similar  claims  before  administrative  bodies  in  the  United  States  or  abroad,  even  outside  the
context  of  litigation.  Such  mechanisms  include  re-examination,  post  grant  review  and  equivalent  proceedings  in  foreign  jurisdictions,  e.g.  opposition
proceedings. Such proceedings could result in revocation or amendment of UT’s patents in such a way that they no longer cover our product candidates or
competitive products. The outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to validity, for example, we
cannot  be  certain  that  there  is  no  invalidating  prior  art,  of  which  UT  and  the  patent  examiner  were  unaware  during  prosecution.  If  a  defendant  were  to
prevail on a legal assertion of invalidity and/or unenforceability, we would lose at least part, and perhaps all, of the patent protection on any of our product
candidates. Such a loss of patent protection would have a material adverse impact on our business. 

33

 
 
 
 
 
 
 
 
In the future, we may rely on know-how and trade secrets to protect technology, especially in cases in which we believe patent protection is not
appropriate or obtainable. However, know-how and trade secrets are difficult to protect. While we intend to require employees, academic collaborators,
consultants and other contractors to enter into confidentiality agreements, we may not be able to adequately protect our trade secrets or other proprietary or
licensed information. Typically, research collaborators and scientific advisors have rights to publish data and information in which we may have rights.
Enforcing  a  claim  that  a  third  party  illegally  obtained  and  is  using  any  of  our  trade  secrets  is  expensive  and  time  consuming,  and  the  outcome  is
unpredictable. In addition, courts are sometimes less willing to protect trade secrets than patents. Moreover, our competitors may independently develop
equivalent knowledge, methods and know-how.

If we fail to obtain or maintain patent protection or trade secret protection for our product candidates or our technologies, third parties could use
our  proprietary  information,  which  could  impair  our  ability  to  compete  in  the  market  and  adversely  affect  our  ability  to  generate  revenues  and  attain
profitability.

Our  product  candidates  may  infringe  the  intellectual  property  rights  of  others,  which  could  increase  our  costs  and  delay  or  prevent  our
development  and  commercialization  efforts.  Our  success  depends  in  part  on  avoiding  infringement  of  the  proprietary  technologies  of  others.  The
pharmaceutical industry has been characterized by frequent litigation regarding patent and other intellectual property rights. Identification of third-party
patent rights that may be relevant to our proprietary technology is difficult because patent searching is imperfect due to differences in terminology among
patents,  incomplete  databases  and  the  difficulty  in  assessing  the  meaning  of  patent  claims.  Additionally,  because  patent  applications  are  maintained  in
secrecy  until  the  application  is  published,  we  may  be  unaware  of  third-party  patents  that  may  be  infringed  by  commercialization  of  any  of  our  product
candidates or any future product candidate. There may be certain issued patents and patent applications claiming subject matter that we may be required to
license in order to research, develop or commercialize any of our product candidates, and we do not know if such patents and patent applications would be
available to license on commercially reasonable terms, or at all. Any claims of patent infringement asserted by third parties would be time-consuming and
may:

● result in costly litigation;

● divert the time and attention of our technical personnel and management;

● prevent us from commercializing a product until the asserted patent expires or is held finally invalid or not infringed in a court of law;

● require us to cease or modify our use of the technology and/or develop non-infringing technology; or

● require us to enter into royalty or licensing agreements.

Third parties may hold proprietary rights that could prevent any of our product candidates from being marketed. Any patent-related legal action
against  us  claiming  damages  and  seeking  to  enjoin  commercial  activities  relating  to  any  of  our  product  candidates  or  our  processes  could  subject  us  to
potential liability for damages and require us to obtain a license to continue to manufacture or market any of our product candidates or any future product
candidates.  We  cannot  predict  whether  we  would  prevail  in  any  such  actions  or  that  any  license  required  under  any  of  these  patents  would  be  made
available on commercially acceptable terms, if at all. In addition, we cannot be sure that we could redesign our product candidates or any future product
candidates or processes to avoid infringement, if necessary. Accordingly, an adverse determination in a judicial or administrative proceeding, or the failure
to obtain necessary licenses, could prevent us from developing and commercializing any of our product candidates or a future product candidate, which
could harm our business, financial condition and operating results.

34

 
 
 
 
 
 
 
 
 
 
 
We expect that there are other companies, including major pharmaceutical companies, working in the areas competitive to our product candidates
which either has resulted, or may result, in the filing of patent applications that may be deemed related to our activities. If we were to challenge the validity
of these or any issued United States patent in court, we would need to overcome a statutory presumption of validity that attaches to every issued United
States patent. This means that, in order to prevail, we would have to present clear and convincing evidence as to the invalidity of the patent’s claims. If we
were to challenge the validity of these or any issued United States patent in an administrative trial before the Patent Trial and Appeal Board in the U.S.
PTO, we would have to prove that the claims are unpatentable by a preponderance of the evidence. There is no assurance that a jury and/or court would
find  in  our  favor  on  questions  of  infringement,  validity  or  enforceability.  Even  if  we  are  successful,  litigation  could  result  in  substantial  costs  and  be  a
distraction to management.

We may be subject to claims that we have wrongfully hired an employee from a competitor or that we or our employees have wrongfully used
or disclosed alleged confidential information or trade secrets of their former employers. As is commonplace in our industry, we will employ individuals
who were previously employed at other pharmaceutical companies, including our competitors or potential competitors. Although no claims against us are
currently pending, we may be subject in the future to claims that our employees or prospective employees are subject to a continuing obligation to their
former employers (such as non-competition or non-solicitation obligations) or claims that our employees or we have inadvertently or otherwise used or
disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. Even if we
are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management. 

Risks Related to Owning Our Common Stock

An  active,  liquid  and  orderly  trading  market  for  our  shares  may  not  develop,  which  may  inhibit  the  ability  of  our  stockholders  to  sell  their
shares. We recently commenced trading on the Nasdaq Capital Market, under the symbol “TFFP,” on October 25, 2019, and since that date our common
shares have been thinly traded. There can be no assurance that an active, liquid or orderly trading market in our shares will develop or, if it does develop,
that it will be sustained. The lack of an active market may impair your ability to sell your shares at the time you wish to sell them or at a price that you
consider reasonable. The lack of an active market may also reduce the fair market value of your shares. An inactive market may also impair our ability to
raise capital by selling shares and may impair our ability to acquire other companies by using our shares as consideration.

Our failure to meet the continued listing requirements of NASDAQ could result in a delisting of our common stock. If we fail to satisfy the
continued listing requirements of NASDAQ, such as the corporate governance requirements or the minimum closing bid price requirement, NASDAQ may
take steps to delist our common stock. Such a delisting would likely have a negative effect on the price of our common stock and would impair your ability
to sell or purchase our common stock when you wish to do so. In the event of a delisting, we can provide no assurance that any action taken by us to restore
compliance  with  listing  requirements  would  allow  our  common  stock  to  become  listed  again,  stabilize  the  market  price  or  improve  the  liquidity  of  our
common  stock,  prevent  our  common  stock  from  dropping  below  the  NASDAQ  minimum  bid  price  requirement  or  prevent  future  non-compliance  with
NASDAQ’s listing requirements.

Future capital raises may dilute your ownership and/or have other adverse effects on our operations. If we raise additional capital by issuing
equity securities, our existing stockholders’ percentage ownership will be reduced and these stockholders may experience substantial dilution. If we raise
additional funds by issuing debt securities, these debt securities would have rights senior to those of our common stock and the terms of the debt securities
issued  could  impose  significant  restrictions  on  our  operations,  including  liens  on  our  assets.  If  we  raise  additional  funds  through  collaborations  and
licensing arrangements, we may be required to relinquish some rights to our intellectual property or candidate products, or to grant licenses on terms that
are not favorable to us.

The market price of our shares may be subject to fluctuation and volatility. You could lose all or part of your investment. The public offering
price for the shares in our initial public offering was determined by negotiations between us and the underwriter and may not be indicative of prices that
will prevail in the trading market. The stock market in general, and early stage public companies in particular, has experienced extreme price and volume
fluctuations that have often been unrelated or disproportionate to the operating performance of such companies. The stock market in general has been, and
the  market  price  of  our  shares  in  particular  will  likely  be,  subject  to  fluctuation,  whether  due  to,  or  irrespective  of,  our  operating  results  and  financial
condition. The market price of our shares on the NASDAQ Capital Market may fluctuate as a result of a number of factors, some of which are beyond our
control, including, but not limited to:

● actual or anticipated variations in our and our competitors’ results of operations and financial condition;

35

 
 
 
 
 
 
 
 
 
 
● market acceptance of our product candidates;

● changes in earnings estimates or recommendations by securities analysts, if our shares are covered by analysts;

● development of technological innovations or new competitive products by others;

● announcements of technological innovations or new products by us;

● publication of the results of preclinical or clinical trials for our product candidates;

● failure by us to achieve a publicly announced milestone;

● delays between our expenditures to develop and market new or enhanced products and the generation of sales from those products;

● developments concerning intellectual property rights, including our involvement in litigation brought by or against us;

● regulatory developments and the decisions of regulatory authorities as to the approval or rejection of new or modified products;

● changes in the amounts that we spend to develop, acquire or license new products, technologies or businesses;

● changes in our expenditures to promote our product candidates;

● our sale or proposed sale, or the sale by our significant stockholders, of our shares or other securities in the future;

● changes in key personnel;

● success or failure of our research and development projects or those of our competitors;

● the trading volume of our shares; and

● general economic and market conditions and other factors, including factors unrelated to our operating performance.

These factors and any corresponding price fluctuations may materially and adversely affect the market price of our shares and result in substantial
losses being incurred by our investors. In the past, following periods of market volatility, public company stockholders have often instituted securities class
action  litigation.  If  we  were  involved  in  securities  litigation,  it  could  impose  a  substantial  cost  upon  us  and  divert  the  resources  and  attention  of  our
management from our business. 

36

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We  are  an  “emerging  growth  company”  under  the  JOBS  Act  of  2012  and  we  cannot  be  certain  if  the  reduced  disclosure  requirements
applicable to emerging growth companies will make our common stock less attractive to investors. We are an “emerging growth company,” as defined in
the Jumpstart Our Business Startups Act of 2012, or JOBS Act, and we may take advantage of certain exemptions from various reporting requirements that
are applicable to other public companies that are not “emerging growth companies” including, but not limited to:

● not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act;

● reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements;

● exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden

parachute payments; and

● extended transition periods available for complying with new or revised accounting standards.

We  have  chosen  to  take  advantage  of  all  of  the  benefits  available  under  the  JOBS  Act,  including  the  exemptions  discussed  above.  We  cannot
predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less
attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

We will remain an “emerging growth company” for up to five years, although we will lose that status sooner if our revenues exceed $1.07 billion,
if we issue more than $1 billion in non-convertible debt in a three year period, or if the market value of our common stock that is held by non-affiliates
exceeds $700 million as of June 30 in any future year.

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial
results or prevent fraud. Commencing with our annual report on Form 10-K for the fiscal year ended December 31, 2020, we will be required to provide a
report  on  management’s  assessment  of  our  internal  control  over  financial  reporting.  Once  we  are  neither  an  emerging  growth  company  nor  a  non-
accelerated  filed,  we  will  be  required  to  obtain  an  attestation  from  our  independent  registered  public  accounting  firm  on  our  internal  control  report.
Effective internal controls over financial reporting are necessary for us to provide reliable financial reports and, together with adequate disclosure controls
and  procedures,  are  designed  to  prevent  fraud.  Any  failure  to  implement  required  new  or  improved  controls,  or  difficulties  encountered  in  their
implementation could cause us to fail to meet our reporting obligations. In addition, any testing by us conducted in connection with Section 404 of the
Sarbanes-Oxley Act, or the subsequent testing by our independent registered public accounting firm when required, may reveal deficiencies in our internal
controls  over  financial  reporting  that  are  deemed  to  be  material  weaknesses  or  that  may  require  prospective  or  retrospective  changes  to  our  financial
statements  or  identify  other  areas  for  further  attention  or  improvement.  Inferior  internal  controls  could  also  cause  investors  to  lose  confidence  in  our
reported financial information, which could have a negative effect on the trading price of our common shares. There is also a risk that neither we nor our
independent registered public accounting firm (when applicable in the future) will be able to conclude within the prescribed timeframe that internal controls
over financial reporting is effective as required by Section 404. As a result, investors could lose confidence in our financial and other public reporting,
which would harm our business and the trading price of our common stock.

Our status as an “emerging growth company” under the JOBS Act may make it more difficult to raise capital as and when we need it. Because
of the exemptions from various reporting requirements provided to us as an “emerging growth company,” we may be less attractive to investors and it may
be difficult for us to raise additional capital as and when we need it. Investors may be unable to compare our business with other companies in our industry
if they believe that our reporting is not as transparent as other companies in our industry. If we are unable to raise additional capital as and when we need it,
our financial condition and results of operations may be materially and adversely affected.

37

 
 
 
 
 
 
 
 
 
 
 
We have not paid dividends in the past and have no immediate plans to pay dividends. We plan to reinvest all of our earnings, to the extent we
have  earnings,  to  cover  operating  costs  and  otherwise  become  and  remain  competitive.  We  do  not  plan  to  pay  any  cash  dividends  with  respect  to  our
securities  in  the  foreseeable  future.  We  cannot  assure  you  that  we  would,  at  any  time,  generate  sufficient  surplus  cash  that  would  be  available  for
distribution to the holders of our common stock as a dividend. Therefore, you should not expect to receive cash dividends on our common stock. 

If equity research analysts do not publish research or reports about our business or if they issue unfavorable commentary or downgrade our
shares, the price of our shares could decline. The trading market for our shares will rely in part on the research and reports that equity research analysts
publish  about  us  and  our  business,  if  at  all.  We  do  not  have  control  over  these  analysts  and  we  do  not  have  commitments  from  them  to  write  research
reports  about  us.  The  price  of  our  shares  could  decline  if  no  research  reports  are  published  about  us  or  our  business,  or  if  one  or  more  equity  research
analysts downgrades our shares or if those analysts issue other unfavorable commentary or cease publishing reports about us or our business.

We will incur significant increased costs as a result of becoming a public company that reports to the Securities and Exchange Commission
and our management will be required to devote substantial time to meet compliance obligations. As a public company reporting to the Securities and
Exchange Commission, we will incur significant legal, accounting and other expenses that we did not incur as a private company. We will be subject to
reporting requirements of the Securities Exchange Act of 1934, or the Exchange Act, and the reporting and governance provisions of the Sarbanes-Oxley
Act  of  2002  and  the  Dodd-Frank  Wall  Street  Reform  and  Protection Act,  as  well  as  rules  subsequently  implemented  by  the  Securities  and  Exchange
Commission,  that  impose  significant  requirements  on  public  companies,  including  requiring  establishment  and  maintenance  of  effective  disclosure  and
financial controls and changes in corporate governance practices. There are significant corporate governance and reporting provisions in these laws that
will increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly and may also place undue strain on
our  personnel,  systems  and  resources.  Our  management  and  other  personnel  will  need  to  devote  a  substantial  amount  of  time  to  these  regulations.  In
addition, we expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance, and we
may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may
be more difficult for us to attract and retain qualified people to serve on our board of directors, or Board, our Board committees or as executive officers.

Assuming a market for our common stock develops, shares eligible for future sale may adversely affect the market for our common stock. We,
all of our directors and officers, and all of our common shares outstanding prior to our initial public offering, are subject to lock-up agreements whereby the
holder has agreed not to sell, transfer, pledge or lend, or offer to do any of the same, directly or indirectly, any of our securities for a period of one year
following the October 29, 2019 close of our initial public offering. The holders of common shares issuable upon conversion of our Series A preferred stock
have agreed not to sell, transfer, pledge or lend, or offer to do any of the same, directly or indirectly, any of our securities for 180 days following the close
of our initial public offering, other than certain holders who purchased our Series A preferred stock as part of our May 2019 private placement and are
deemed  “related  persons”  under  the  rules  of  FINRA,  who  have  agreed  to  a  one-year  lock-up  period.  Notwithstanding  the  lock-up  agreements,  we  have
agreed to register for resale shares of common stock expected to be issued upon conversion of our Series A preferred stock and shares of common stock
underlying certain warrants. Furthermore, after the 180th day following the close of our initial public offering, certain stockholders will be eligible to begin
publicly selling their shares under Rule 144, promulgated under the Securities Act of 1933, or the Securities Act. Rule 144 becomes available to the holders
of our restricted stock on the 90th day following the close of our initial public offering. However, as noted above, the holders of our restricted stock have
agreed not to publicly sell any restricted stock pursuant to Rule 144 or otherwise for at least 180 days following the close of our initial public offering. See
“Shares Eligible for Future Sale”. Any substantial sale of our common stock pursuant to Rule 144 or pursuant to any resale prospectus (including sales by
investors of securities acquired in connection with this offering) may have a material adverse effect on the market price of our common stock.

38

 
 
 
 
 
 
We may be at an increased risk of securities class action litigation. Historically, securities class action litigation has often been brought against a
company  following  a  decline  in  the  market  price  of  its  securities.  This  risk  is  especially  relevant  for  us  because  biotechnology  and  pharmaceutical
companies have experienced significant stock price volatility in recent years. If we were to be sued, it could result in substantial costs and a diversion of
management’s attention and resources, which could harm our business.

Our charter documents and Delaware law may inhibit a takeover that stockholders consider favorable. The provisions of our second amended
and  restated  certificate  of  incorporation,  or  Certificate,  and  amended  and  restated  bylaws  and  applicable  provisions  of  Delaware  law  may  delay  or
discourage transactions involving an actual or potential change in control or change in our management, including transactions in which stockholders might
otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests. The provisions in our
Certificate and amended and restated bylaws:

● limit who may call stockholder meetings;

● do not provide for cumulative voting rights; and

● provide that all board vacancies may be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum.

In addition, Section 203 of the Delaware General Corporation Law may limit our ability to engage in any business combination with a person who
beneficially  owns  15%  or  more  of  our  outstanding  voting  stock  unless  certain  conditions  are  satisfied.  This  restriction  lasts  for  a  period  of  three  years
following the share acquisition. These provisions may have the effect of entrenching our management team and may deprive you of the opportunity to sell
your shares to potential acquirers at a premium over prevailing prices. This potential inability to obtain a control premium could reduce the price of our
common stock. 

Our Certificate and amended and restated bylaws designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for
certain litigation that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes
with us or our directors, officers or other employees. Provisions in our Certificate and amended and restated bylaws provide that the Court of Chancery of
the State of Delaware will, to the fullest extent permitted by law, be the sole and exclusive forum for:

● any derivative action or proceeding brought on our behalf;

● any action asserting a claim of breach of a fiduciary duty owed to us or our stockholders by any of our directors, officers or other employees;

● any action asserting a claim against us or any of our directors, officers or other employees arising pursuant to any provision of Delaware law

or our charter documents; or

● any  action  asserting  a  claim  against  us  or  any  of  our  directors,  officers  or  other  employees  governed  by  the  internal  affairs  doctrine,  but
excluding actions to enforce a duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive
jurisdiction.

These  exclusive  forum  provisions  do  not  apply  to  claims  under  the  Securities  Act  or  the  Exchange  Act.  These  exclusive  forums  provisions,
however, do provide that if no state court located in the State of Delaware has jurisdiction, the federal district court for the District of Delaware shall be the
exclusive forum. By becoming a stockholder in our company, you will be deemed to have notice of and have consented to the provisions of our Certificate
and amended and restated bylaws related to choice of forum, but will not be deemed to have waived our compliance with the federal securities laws and the
rules and regulations thereunder. The choice of forum provisions in our Certificate and amended and restated bylaws may limit our stockholders’ ability to
obtain a favorable judicial forum for disputes with us or any of our directors, officers or other employees, which may discourage lawsuits with respect to
such  claims. Alternatively,  if  a  court  were  to  find  the  choice  of  forum  provision  contained  in  our  Certificate  and  amended  and  restated  bylaws  to  be
inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our
business, results of operations and financial condition.

Equity Compensation Plan Information

We have adopted the TFF Pharmaceuticals, Inc. 2018 Stock Incentive Plan providing for the grant of non-qualified stock options and incentive

During the fiscal year ended December 31, 2019, we issued, in May 2019, 3,268,000 shares of our Series A preferred stock, at an offering price of
$2.50 per share, for the gross proceeds of approximately $8.2 million ($7.3 million after deducting offering expenses). In connection with the close of our
initial  public  offering,  we  issued  9,571,692  shares  of  our  common  stock  upon  the  conversion  of  all  outstanding  shares  of  our  Series  A  preferred  stock,
which included of 5,662,000 shares of our Series A preferred stock issued in March 2018 and the conversion of all accrued and unpaid dividends. All of the
aforementioned issuances were exempt under Section 4(a)(2) of the Securities Act of 1933 and Rule 506 there under. All of the investors were accredited

Item 6. Selected Financial Data

Not applicable.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

General

We  were  formed  as  a  Delaware  corporation  on  January  24,  2018  for  the  purpose  of  developing  and  commercializing  innovative  drug  products
based on our patented Thin Film Freezing, or TFF, technology platform”. Since our formation, we have focused on the development of our initial drug
candidates, the establishment of strategic relationships with established pharmaceutical companies for the licensing of our TFF technology platform and the
pursuit of additional working capital. We have not commenced revenue-producing operations.

Since our organization in 2018, we have engaged in the following financing transactions:

Series A Preferred Stock Placements. In March 2018, we conducted a private placement of 5,662,000 shares of our Series A preferred stock, at an
offering price of $2.50 per share, for the gross proceeds of approximately $14.2 million, and in May 2019 we conducted a private placement of 3,268,000
shares of our Series A preferred stock, at an offering price of $2.50 per share, for the gross proceeds of approximately $8.2 million. The shares of our Series
A preferred stock accumulated dividends at the rate of 6% per annum. The shares of Series A preferred stock, including all accrued but unpaid dividends on
the  Series  A  preferred  stock,  which  totalled  $1,603,709,  automatically  converted  into  9,571,692  shares  of  our  common  stock  concurrent  with  the
completion of our initial public offering at the conversion price of $2.50.

42

 
 
 
 
 
 
   
   
   
 
 
 
 
 
 
 
 
 
 
Initial Public Offering. On October 25, 2019, we conducted an initial public offering of 4,400,000 shares of common stock at a public offering
price  of  $5.00  per  share.  After  the  payment  of  underwriter  discounts  and  offering  expenses,  and  after  giving  effect  to  the  underwriters’  exercise  of  its
overallotment option on November 20, 2019 to purchase an additional 479,300 shares of our common stock at the offering price of $5.00 per share, we
received net proceeds of approximately $21.8 million.

Results of Operations

We  were  formed  in  January  2018  and  have  not  commenced  revenue-producing  operations.  To  date,  our  operations  have  consisted  of  the
development  and  early-stage  testing  of  our  initial  product  candidates.  In  connection  with  our  organization  on  January  24,  2018,  we  entered  into  a
Contribution and Subscription Agreement with Lung Therapeutics, Inc., or LTI, our former parent, pursuant to which we agreed to acquire from LTI certain
of LTI’s non-core intellectual property rights and other assets, or the Acquired Assets, all of which relate to our Thin Film Freezing technology. We closed
on  the  acquisition  of  the  Acquired  Assets  concurrent  with  the  close  of  the  initial  Series  A  preferred  stock  financing  in  March  2018.  The  operations
surrounding the Acquired Assets are deemed to be our accounting predecessor and the results of operations in the financial summary below for the period
January 1, 2018 through January 23, 2018 reflect the results of operations of the Acquired Assets, which were immaterial, as our predecessor.

During the fiscal years ended December 31, 2019 and 2018, we incurred $8.8 million and $848,809 of research and development expenses and
$3.2 million and $3.0 million of general and administrative expenses, respectively. The increase in research and development expenses during 2019 was
due  to  the  ramp-up  of  research  and  development  activities  following  the  completion  of  our  funding  in  May  2019.  We  incurred  a  net  loss  applicable  to
common  stockholders  of  $36.7  million  and  $4.6  million  for  the  fiscal  years  ended  December  31,  2019  and  2018,  respectively.  The  increase  in  net  loss
applicable to common stockholders in 2019 was due to a deemed dividend of $24.0 million upon the conversion of our Series A preferred stock in October
2019.

Financial Condition

As  of  December  31,  2019,  we  had  total  assets  of  approximately  $29.2  million  and  working  capital  of  approximately  $28.8  million.  As  of
December 31, 2019, our liquidity included approximately $28.1 million of cash and cash equivalents. We believe that our cash on-hand as of the date of
this report is sufficient to fund our proposed operating plan for, at least, the 12 months following the date of this report. However, as of the date of this
report, we believe that we will ultimately need additional capital to fund our operations through to the marketing approval for TFF Vori and TFF Tac-Lac,
assuming such approval can be obtained at all, and to engage in the substantial development of any other of our drug candidates, such as formulation, early
stage animal testing and formal toxicology studies. We intend to seek additional funds through various financing sources, including the sale of our equity
and debt securities, licensing fees for our technology and co-development and joint ventures with industry partners, with a preference towards licensing
fees for our technology and co-development and joint ventures with industry partners. In addition, we will consider alternatives to our current business plan
that may enable to us to achieve revenue producing operations and meaningful commercial success with a smaller amount of capital. However, there can be
no guarantees that such funds will be available on commercially reasonable terms, if at all. If such financing is not available on satisfactory terms, we may
be unable to further pursue our business plan and we may be unable to continue operations, in which case you may lose your entire investment.

(1) The period from January 1, 2018 through January 23, 2018 was not material

The increase in cash used in operating activities is primarily a result of higher operating losses in 2019 due to our business expansion, including
additional personnel and increased product candidate development activity. The financing activity primarily consists of the Series A preferred stock private
placements in 2018, 2019 and the October 2019 initial public offering, or IPO.

Critical Accounting Policies

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America,
or  GAAP.  The  preparation  of  our  consolidated  financial  statements  and  related  disclosures  requires  us  to  make  estimates  and  judgments  that  affect  the
reported amounts of assets, liabilities, costs and expenses in our consolidated financial statements. We base our estimates on historical experience, known
trends  and  events  and  various  other  factors  that  we  believe  are  reasonable  under  the  circumstances,  the  results  of  which  form  the  basis  for  making
judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on
an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.

While  our  significant  accounting  policies  are  described  in  more  detail  in  Note  3  to  our  consolidated  financial  statements  included  herein,  we
believe that the following accounting policies are those most critical to the judgments and estimates used in the preparation of our consolidated financial
statements.

Stock-Based Compensation

We  compute  stock-based  compensation  in  accordance  with  authoritative  guidance.  We  use  the  Black-Scholes-Merton  option-pricing  model  to
determine the fair value of its stock options. The Black-Scholes-Merton option-pricing model includes various assumptions, including the fair market value
of  our  common  stock,  expected  life  of  stock  options,  the  expected  volatility  and  the  expected  risk-free  interest  rate,  among  others.  These  assumptions
reflect our best estimates, but they involve inherent uncertainties based on market conditions generally outside our control.

As a result, if other assumptions had been used, stock-based compensation cost, as determined in accordance with authoritative guidance, could
have been materially impacted. Furthermore, if we use different assumptions on future grants, stock-based compensation cost could be materially affected
in future periods.

We account for the fair value of equity instruments issued to non-employees using either the fair value of the services received or the fair value of
the  equity  instrument,  whichever  is  considered  more  reliable.  We  utilize  the  Black-Scholes-Merton  option-pricing  model  to  measure  the  fair  value  of
options issued to non-employees.

For grants prior to the IPO, the fair value of the common stock was determined by the board of directors based on a variety of factors, including
valuations prepared by third parties, our financial position, the status of our development efforts, the current climate in the marketplace and the prospects of
a liquidity event, among others. For grants after the IPO, we use the closing stock price on the date of grant as the fair value of the common stock.

Research and Development Expenses

In  accordance  with  authoritative  guidance,  we  charge  research  and  development  costs  to  operations  as  incurred.  Research  and  development
expenses  consist  of  personnel  costs  for  the  design,  development,  testing  and  enhancement  of  our  technology,  and  certain  other  allocated  costs,  such  as
depreciation and other facilities related expenditures.

Common Stock Warrants

We  classify  as  equity  any  warrants  that  (i)  require  physical  settlement  or  net-share  settlement  or  (ii)  provides  us  with  a  choice  of  net-cash
settlement or settlement in its own shares (physical settlement or net-share settlement). We classify as assets or liabilities any contracts that (i) require net-
cash settlement (including a requirement to net cash settle the contract if an event occurs and if that event is outside our control), (ii) gives the counterparty
a choice of net-cash settlement or settlement in shares (physical settlement or net-share settlement) or (iii) that contain reset provisions that do not qualify
for  the  scope  exception.  We  assess  classification  of  its  common  stock  warrants  and  other  freestanding  derivatives  at  each  reporting  date  to  determine
whether a change in classification between assets and liabilities is required. Our freestanding derivatives consist of warrants to purchase common stock that
were issued in connection with services provided to us. We evaluated these warrants to assess their proper classification and determined that the common
stock warrants meet the criteria for equity classification in the consolidated balance sheet. Such warrants are measured at fair value, which we determine
using the Black-Scholes-Merton option-pricing model.

Beneficial Conversion Feature

On the date of the IPO, the outstanding Series A preferred stock, and related accrued and unpaid dividends, automatically converted into shares of
our common stock. The conversion share calculation was based on the $2.50 initial issuance price for the Series A preferred stock plus any accrued but
unpaid dividends and converted to common stock using a stated divisor conversion price equal to 50% of the IPO price to the public, which was $5.00 per
share. In accordance with relevant accounting literature, since the stated terms of the conversion option did not permit us to compute the additional number
of  shares  that  it  would  need  to  issue  upon  conversion  of  the  Series  A  preferred  stock  when  the  contingent  event  occurred,  we  recorded  the  beneficial
conversion amount as a deemed dividend at the date of the IPO.

Off Balance Sheet Transactions

We do not have any off-balance sheet transactions.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors of
TFF Pharmaceuticals, Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of TFF Pharmaceuticals, Inc. (the “Company”) as of December 31, 2019 and 2018, the
related consolidated statements of operations, stockholders’ equity (deficit) and cash flows for the year ended December 31, 2019, period from January 24,
2018  to  December  31,  2018  and  period  from  January  1,  2018  to  January  23,  2018  (Predecessor),  and  the  related  notes  (collectively  referred  to  as  the
“consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of
the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for the year ended December 31, 2019, period from
January  24,  2018  to  December  31,  2018  and  period  from  January  1,  2018  to  January  23,  2018  (Predecessor),  in  conformity  with  accounting  principles
generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s
consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board
(United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States
of America. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements
are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not
for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such
opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or
fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and
disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by
management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis
for our opinion.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

For The Year Ended December 31, 2019, Period From January 24, 2018 to December 31, 2018 and
Period from January 1, 2018 to January 23, 2018 (Predecessor)

NOTE 1 – ORGANIZATION AND DESCRIPTION OF BUSINESS

TFF Pharmaceuticals, Inc. (the “Company”) was incorporated in the State of Delaware on January 24, 2018 by Lung Therapeutics, Inc. (“LTI”), at which
time the Company and LTI entered into a Contribution and Subscription Agreement (“Contribution Agreement”) pursuant to which LTI agreed to transfer
to  the  Company  certain  of  LTI’s  non-core  intellectual  property  rights  and  other  assets,  including  LTI’s  rights  under  a  patent  license  agreement  with  the
University of Texas at Austin (see, Note 5), in exchange for 4,000,000 shares of the Company’s common stock. The transactions under the Contribution
Agreement closed in March 2018. LTI’s basis in such assets were minimal. LTI is an early-stage biotechnology company focused on the development of
certain technologies in the pulmonary field. The Company’s initial focus is on the development of inhaled dry powder drugs to enhance the treatment of
pulmonary diseases and conditions. In December 2019, the Company established a wholly-owned Australian subsidiary, TFF Pharmaceuticals Australia Pty
Ltd  (“TFF  Australia”),  in  order  to  conduct  clinical  research.  TFF  Pharmaceuticals,  Inc.,  along  with  TFF  Australia,  are  collectively  referred  to  as  the
“Company”. The Company is in the development stage, having not yet started planned principal operations, and is devoting substantially all of its efforts
toward technology research and development.

In October 2019, the Company completed an initial public offering (“IPO”), selling 4,400,000 shares of common stock at an offering price of $5.00 per
share.  The  Company  received  gross  proceeds  of  approximately  $22,000,000  (see  Note  7).  In  addition,  the  Company  granted  the  underwriter  a  45-day
option to purchase an additional 660,000 shares of common stock at the initial public offering price, less underwriting discounts and commissions. The
option  was  exercised  in  November  2019  and  the  underwriter  purchased  an  additional  479,300  shares  of  common  stock  and  the  Company  received
additional gross proceeds of approximately $2,397,000.

The accompanying financial statements of the Company for the period from January 1, 2018 to January 23, 2018 reflect the historical results of operations,
changes in net investment and cash flows of the operations for the assets acquired by the Company from LTI, the Company’s former parent. These financial
statements have been derived from the accounting records of LTI and should be read in conjunction with the accompanying notes thereto. The operations
surrounding  the  acquired  assets  is  deemed  to  be  the  Company’s  predecessor  prior  to  January  24,  2018,  the  deemed  date  of  acquisition.  These  financial
statements do not necessarily reflect what the results of operations, financial position, or cash flows would have been had the Company been a separate
entity during the periods prior to January 24, 2018 nor are they indicative of future results of the Company.

All of the assets, liabilities and results of operations of the Company as of and for the period ended January 23, 2018 were identified based on the assets
acquired  by  the  Company  from  LTI.  Management  believes  the  assumptions  underlying  the  Company’s  carve-out  financial  statements  are  reasonable.
Nevertheless, the financial statements may not include all of the actual expenses that would have been incurred had the Company operated as a standalone
company  during  the  periods  presented,  and  may  not  reflect  the  Company’s  results  of  operations,  financial  position  and  cash  flows  had  the  Company
operated as a standalone company during the periods presented. Actual costs that would have been incurred if the Company had operated as a standalone
company  would  depend  on  multiple  factors,  including  organizational  structure  and  strategic  decisions  made  in  various  areas,  including  information
technology and infrastructure.

NOTE 2 - LIQUIDITY AND MANAGEMENT’S PLANS

As  of  December  31,  2019,  the  Company  had  cash  and  cash  equivalents  of  approximately  $28,095,000  and  a  working  capital  surplus  of  approximately
$28,777,000.  The  Company  has  not  generated  revenues  since  inception  and  has  incurred  recurring  operating  losses.  The  Company  expects  to  continue
incurring losses for the foreseeable future and may need to raise additional capital to pursue its product development.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

For The Year Ended December 31, 2019, Period From January 24, 2018 to December 31, 2018 and
Period from January 1, 2018 to January 23, 2018 (Predecessor)

NOTE 2 - LIQUIDITY AND MANAGEMENT’S PLANS, continued

The Company expects to further increase its research and development activities, which will increase the amount of cash utilized subsequent to December
31,  2019.  Specifically,  the  Company  expects  increased  spending  on  research  and  development  activities  and  higher  payroll  expenses  as  it  increases  its
professional  and  scientific  staff  and  continues  to  prepare  for  anticipated  manufacturing  activities. The  Company  currently  believes  its  existing  cash  and
cash  equivalents  will  be  sufficient  to  fund  its  operating  expenses  and  capital  expenditure  requirements  for  at  least  the  next  12  months  from  the  date  of
issuance of these consolidated financial statements.

NOTE 3 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The  Company’s  consolidated  financial  statements  are  presented  in  accordance  with  accounting  principles  generally  accepted  in  the  United  States  of
America  (“GAAP”)  and  the  rules  and  regulations  of  the  Securities  and  Exchange  Commission  (“SEC”)  and  reflect  the  financial  position,  results  of
operations and cash flows for all periods presented.

Principles of Consolidation

The  consolidated  financial  statements  include  the  accounts  of  TFF  Pharmaceuticals,  Inc.  and  its  wholly-owned  subsidiary,  TFF  Australia. All  material
intercompany accounts and transactions have been eliminated in consolidation.

Financial Statements

The financial statements for the periods from January 1, 2018 through January 23, 2018 (predecessor) have been prepared using the accounting records of
LTI. All material inter-company balances and transactions have been eliminated.

Deferred Offering Costs

The Company complies with the requirements of Accounting Standards Codification (“ASC”) 340, Other Assets and Deferred Costs.  Deferred  offering
costs of $127,768 as of December 31, 2018 consisted primarily of legal, accounting and filing fees incurred through the consolidated balance sheet date that
are  related  to  the  Company’s  IPO  and  were  charged  to  capital  upon  completion  of  the  IPO  in  October  2019.  There  are  no  deferred  offering  costs  as  of
December 31, 2019.

Cash and Cash Equivalents

The Company maintains its operating accounts in a single financial institution. The balances are insured by the U.S. Federal Deposit Insurance Corporation
(“FDIC”) up to specified limits. The Company’s cash is maintained in checking accounts and money market funds with maturities of less than three months
when purchased, which are readily convertible to known amounts of cash, and which in the opinion of management are subject to insignificant risk of loss
in value.

NOTE 3 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued

Fair Value of Financial Instruments

Authoritative  guidance  requires  disclosure  of  the  fair  value  of  financial  instruments.  The  Company’s  financial  instruments  consist  of  cash  and  cash
equivalents  and  accounts  payable,  the  carrying  amounts  of  which  approximate  their  estimated  fair  values  primarily  due  to  the  short-term  nature  of  the
instruments  or  based  on  information  obtained  from  market  sources  and  management  estimates.  The  Company  measures  the  fair  value  of  certain  of  its
financial assets and liabilities on a recurring basis. A fair value hierarchy is used to rank the quality and reliability of the information used to determine fair
values.  Financial  assets  and  liabilities  carried  at  fair  value  which  is  not  equivalent  to  cost  will  be  classified  and  disclosed  in  one  of  the  following  three
categories:

Level 1 — Quoted prices (unadjusted) in active markets for identical assets and liabilities.
Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as unadjusted quoted prices for similar assets and liabilities,
unadjusted  quoted  prices  in  the  markets  that  are  not  active,  or  other  inputs  that  are  observable  or  can  be  corroborated  by  observable  market  data  for
substantially the full term of the assets or liabilities.
Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Income Taxes

In accordance with authoritative guidance, deferred tax assets and liabilities are recorded for temporary differences between the financial reporting and tax
bases of assets and liabilities using the current enacted tax rate expected to be in effect when the differences are expected to reverse. A valuation allowance
is recorded on deferred tax assets unless realization is considered more likely than not.

The Company evaluates its tax positions taken or expected to be taken in the course of preparing the Company’s tax returns to determine whether the tax
positions  are  “more-likely-than-not”  of  being  sustained  by  the  applicable  tax  authority.  Tax  positions  not  deemed  to  meet  the  “more-likely-than-not”
threshold are not recorded as a tax benefit or expense in the current year. The Company recognizes interest and penalties, if any, related to uncertain tax
positions in interest expense. No interest and penalties related to uncertain tax positions were accrued at either December 31, 2019 or 2018.

The Company follows authoritative guidance which requires the evaluation of existing tax positions. The Company files in the federal and various state
jurisdictions. Management has analyzed all open tax years, as defined by the statute of limitations, for all major jurisdictions. Open tax years are those that
are open for examination by taxing authorities. The Company was incorporated during 2018 which is the only open year at this time.

Research and Development Expenses

In  accordance  with  authoritative  guidance,  the  Company  charges  research  and  development  costs  to  operations  as  incurred.  Research  and  development
expenses consist of personnel costs for the design, development, testing and enhancement of the Company’s technology, and certain other allocated costs,
such as depreciation and other facilities related expenditures.

Basic and Diluted Earnings per Common Share

Basic  net  loss  per  common  share  is  calculated  by  dividing  the  net  loss  by  the  weighted-average  number  of  common  shares  outstanding  for  the  period.
Diluted  net  loss  per  share  is  computed  by  dividing  the  net  loss  by  the  weighted-average  number  of  common  shares  and  dilutive  share  equivalents
outstanding for the period, determined using the treasury-stock and if-converted methods. Since the Company has had net losses for all periods presented,
all potentially dilutive securities are anti-dilutive. Basic weighted average shares outstanding for the year ended December 31, 2019 and the period from
January 24, 2018 to December 31, 2018 include 400,000 shares underlying a warrant to purchase common shares. As the shares underlying this warrant can
be issued for little consideration (an aggregate exercise price of $0.01 per share), these shares are deemed to be issued for purposes of basic earnings per
share.

For the year ended December 31, 2019 and the period from January 24, 2018 to December 31, 2018, the Company had the following potential common
stock equivalents outstanding which were not included in the calculation of diluted net loss per common share because inclusion thereof would be anti-
dilutive:

The Company classifies as equity any warrants that (i) require physical settlement or net-share settlement or (ii) provide the Company with a choice of net-
cash settlement or settlement in its own shares (physical settlement or net-share settlement). The Company classifies as assets or liabilities any contracts
that (i) require net-cash settlement (including a requirement to net cash settle the contract if an event occurs and if that event is outside the Company’s
control), (ii) gives the counterparty a choice of net-cash settlement or settlement in shares (physical settlement or net-share settlement) or (iii) that contain
reset  provisions  that  do  not  qualify  for  the  scope  exception.  The  Company  assesses  classification  of  its  common  stock  warrants  and  other  freestanding
derivatives at each reporting date to determine whether a change in classification between assets and liabilities is required. The Company’s freestanding
derivatives consist of warrants to purchase common stock that were issued in connection with services provided to the Company. The Company evaluated
these  warrants  to  assess  their  proper  classification  and  determined  that  the  common  stock  warrants  meet  the  criteria  for  equity  classification  in  the
consolidated  balance  sheet.  Such  warrants  are  measured  at  fair  value,  which  the  Company  determines  using  the  Black-Scholes-Merton  option-pricing
model.

Beneficial Conversion Feature

On  the  date  of  the  IPO,  the  outstanding  Series  A  Convertible  Preferred  Stock  (“Series  A  Preferred  Stock”),  and  related  accrued  and  unpaid  dividends,
automatically converted into shares of the Company’s common stock. The conversion share calculation was based on the $2.50 initial issuance price for the
Series A Preferred Stock plus any accrued but unpaid dividends and converted to common stock using a stated divisor conversion price equal to 50% of the
IPO price to the public, which was $5.00 per share. In accordance with relevant accounting literature, since the stated terms of the conversion option did
not permit the Company to compute the additional number of shares that it would need to issue upon conversion of the Series A Preferred Stock when the
contingent event occurred, the Company recorded the beneficial conversion amount of approximately $23,930,000 as a deemed dividend at the date of the
IPO.

Stock-Based Compensation

The  Company  computes  stock-based  compensation  in  accordance  with  authoritative  guidance.  The  Company  uses  the  Black-Scholes-Merton  option-
pricing model to determine the fair value of its stock options. The Black-Scholes-Merton option-pricing model includes various assumptions, including the
fair  market  value  of  the  common  stock  of  the  Company,  expected  life  of  stock  options,  the  expected  volatility  and  the  expected  risk-free  interest  rate,
among  others.  These  assumptions  reflect  the  Company’s  best  estimates,  but  they  involve  inherent  uncertainties  based  on  market  conditions  generally
outside the control of the Company.

As a result, if other assumptions had been used, stock-based compensation cost, as determined in accordance with authoritative guidance, could have been
materially impacted. Furthermore, if the Company uses different assumptions on future grants, stock-based compensation cost could be materially affected
in future periods.

The Company accounts for the fair value of equity instruments issued to non-employees using either the fair value of the services received or the fair value
of the equity instrument, whichever is considered more reliable. The Company utilizes the Black-Scholes-Merton option-pricing model to measure the fair
value of options issued to non-employees.

Parent Net Deficit

LTI’s  net  investment  in  the  Company’s  business  is  presented  as  “Parent  Net  Deficit”  in  lieu  of  stockholders’  equity  in  the  Statement  of  Stockholders’
Equity (Deficit). The changes in Parent’s Net Deficit on the Statement of Stockholders’ Equity (Deficit) include net cash transfers between LTI and the
Company. LTI performed cash management and other treasury-related functions on a centralized basis for all of its divisions, which included the Company.
Liabilities recorded by LTI, whose related expenses were pushed down to the Company, are included in Parent Net Deficit.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the
reported amounts of expenses during the reporting period. Significant estimates include the fair value of stock-based compensation and warrants, valuation
allowance against deferred tax assets and related disclosures. Actual results could differ from those estimates.

Recent Accounting Standards

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, Leases (Topic 842). This ASU will require lessees to
recognize a ROU asset and lease liability on the consolidated balance sheet for leases with terms longer than 12 months. Leases will be classified as either
finance  or  operating,  with  classification  affecting  the  pattern  of  expense  recognition  in  the  income  statement.  In  July  2018,  the  FASB  issued  ASU  No.
2018-10, Codification Improvements to Topic 842, Leases and ASU No. 2018-11, Leases (Topic 842): Targeted Improvements. /ASU No. 2018-10 provides
certain amendments that affect narrow aspects of the guidance issued in ASU No. 2016-02. ASU No. 2018-11 allows entities the option to prospectively
apply the new lease standard at the adoption date instead of recording the cumulative impact of all comparative reporting periods presented within retained
earnings. This guidance is effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within those
fiscal years, and effective for all other entities for fiscal years beginning after December 15, 2019 and interim periods within fiscal years beginning after
December 15, 2020. The Company is currently evaluating this standard.

In July 2017, the FASB issued Accounting Standards Update (“ASU”) 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity
(Topic 480) and Derivatives and Hedging (Topic 815): I. Accounting for Certain Financial Instruments with Down Round Features; II. Replacement of the
Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling
Interests with a Scope Exception, (ASU 2017-11). Part I of this update addresses the complexity of accounting for certain financial instruments with down
round features. Down round features are features of certain equity-linked instruments (or embedded features) that result in the strike price being reduced on
the  basis  of  the  pricing  of  future  equity  offerings.  Current  accounting  guidance  creates  cost  and  complexity  for  entities  that  issue  financial  instruments
(such  as  warrants  and  convertible  instruments)  with  down  round  features  that  require  fair  value  measurement  of  the  entire      instrument  or  conversion
option. Part II of this update addresses the difficulty of navigating Topic 480, Distinguishing Liabilities from Equity, because of the existence of extensive
pending content in the FASB Accounting Standards Codification. This pending content is the result of the indefinite deferral of accounting requirements
about  mandatorily  redeemable  financial  instruments  of  certain  nonpublic  entities  and  certain  mandatorily  redeemable  noncontrolling  interests.  The
amendments in Part II of this update do not have an accounting effect. This guidance is effective for public business entities for fiscal years beginning after
December 15, 2018, including interim periods within those fiscal years, and effective for all other entities for fiscal years beginning after December 15,
2019 and interim periods within fiscal years beginning after December 15, 2020. The Company is currently evaluating this standard.

In  June  2018,  the  FASB  issued  ASU  No.  2018-07,  Compensation  —  Stock  Compensation  (Topic  718):  Improvements  to  Nonemployee  Share-Based
Payment Accounting.  The  guidance  in  this  ASU  expands  the  scope  of  ASC  Topic  718  to  include  all  share-based  payment  arrangements  related  to  the
acquisition of goods and services from both nonemployees and employees. This guidance is effective for public business entities for fiscal years beginning
after December 15, 2018, including interim periods within those fiscal years, and effective for all other entities for fiscal years beginning after December
15, 2019 and interim periods within fiscal years beginning after December 15, 2020. The Company is currently evaluating this standard.

In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820), - Disclosure Framework - Changes to the Disclosure Requirements
for  Fair  Value  Measurement,”  which  makes  a  number  of  changes  meant  to  add,  modify  or  remove  certain  disclosure  requirements  associated  with  the
movement  amongst  or  hierarchy  associated  with  Level  1,  Level  2  and  Level  3  fair  value  measurements.  This  guidance  is  effective  for  fiscal  years,  and
interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted upon issuance of the update. The Company is
currently evaluating this standard.

Operating Leases

In October 2018, the Company entered into a lease agreement for office space in Doylestown, Pennsylvania. The lease commenced on October 15, 2018
and the Company exercised a one-year lease renewal in October 2019 that will expire on October 31, 2020. The lease has an additional one-year option for
renewal, and the base rent is $36,000 per year.

Approximate future minimum lease payments required under the operating leases are as follows:

The Company may be involved, from time to time, in legal proceedings and claims arising in the ordinary course of its business. Such matters are subject to
many uncertainties and outcomes and are not predictable with assurance. While management believes that such matters are currently insignificant, matters
arising  in  the  ordinary  course  of  business  for  which  the  Company  is  or  could  become  involved  in  litigation  may  have  a  material  adverse  effect  on  its
business and financial condition. To the Company’s knowledge, neither the Company nor any of its properties are subject to any pending legal proceedings.

NOTE 5 - LICENSE AND AGREEMENTS

In July 2015, the University of Texas at Austin (“UT”) granted to the Company’s former parent, LTI, an exclusive worldwide, royalty bearing license to the
patent rights for the TFF platform in all fields of use, other than vaccines for which LTI received a non-exclusive worldwide, royalty bearing license to the
patent rights for the TFF platform. In March 2018, LTI completed an assignment to the Company all of its interest to the TFF platform, including the patent
license  agreement  with  UT,  at  which  time  the  Company  paid  UT  an  assignment  fee  of  $100,000  in  accordance  with  the  patent  license  agreement.  In
November 2018, the Company and UT entered into an amendment to the patent license agreement pursuant to which, among other things, the Company’s
exclusive patent rights to the TFF platform were expanded to all fields of use. The patent license agreement requires the Company to pay royalties and
milestone  payments  and  conform  to  a  variety  of  covenants  and  agreements,  and  in  the  event  of  the  Company’s  breach  of  agreement,  UT  may  elect  to
terminate the agreement. For the period ended December 31, 2018, the Company did not achieve any of the milestones and, as such, was not required to
make any milestone payments. For the year ended December 31, 2019, the Company achieved one milestone by gaining IND approval on first indication of
a  licensed  product  on  November  24,  2019.  The  milestone  fee  associated  with  this  achievement  to  be  paid  is  $50,000  and  the  Company  must  issue  UT
common shares equal to 1% of the Company’s outstanding shares of common stock, on a fully diluted basis, as of 30 days after IND approval, which was
December 24, 2019. The total amount of common shares due and payable on December 31, 2019 to UT are 220,666 common shares, which have a fair
value of approximately $1,132,000 based on the closing stock price of $5.13 on December 24, 2019. As of December 31, 2019, the Company has not paid
the  $50,000  or  issued  the  shares  and  has  included  the  $50,000  in  accounts  payable  and  the  share  amount  due  as  a  research  and  development  expense
payable. The Company paid the $50,000 and issued the shares in January 2020. As of the date of these consolidated financial statements, the Company is in
compliance with the patent license agreement as all required amounts have been paid in accordance with the agreement.

NOTE 7 – STOCKHOLDERS’ EQUITY (DEFICIT)

Common Stock

In October 2019, the Company completed an IPO, selling 4,400,000 shares of common stock at an offering price of $5.00 per share. The Company received
gross proceeds of approximately $22,000,000. In addition, the Company granted the underwriter a 45-day option to purchase an additional 660,000 shares
of common stock at the initial public offering price. The option was exercised and the underwriter purchased an additional 479,300 shares of common stock
and the Company received additional gross proceeds of approximately $2,397,000. The Company received net proceeds from the IPO and the underwriter’s
purchase  of  additional  shares  of  approximately  $21,754,000,  after  deducting  underwriting  discounts  and  commissions  and  offering-related  expenses.
Warrants  for  317,155  shares  of  the  Company’s  common  stock  were  issued  to  the  IPO  underwriter  at  an  exercise  price  of  $6.25  per  share  as  part  of  the
underwriter’s compensation for the IPO. The estimated fair value of the warrants of approximately $977,000 was considered an offering cost and netted
against additional paid-in capital.

In conjunction with the IPO, the Company’s outstanding shares of Series A Preferred Stock automatically converted into 9,571,692 shares of its common
stock (see below). Also in conjunction with the issuance of shares in the IPO, the Company granted options to officers and directors to purchase 627,984
shares of common stock at an exercise price of $5.00.

Series A Convertible Preferred Stock

The Company is authorized to issue up to 10,000,000 shares of preferred stock, $0.001 par value, all of which has been designated as Series A Preferred
Stock and has a stated value of $2.50 per share. As of December 31, 2019 and 2018, there are 0 and 5,662,000 shares, respectively, issued and outstanding.
The Series A Preferred Stock ranks senior to common stock with respect to dividends rights and liquidation preferences and has full voting rights. The
Series A Preferred Stock accrues a dividend at a rate of 6% per annum, and such amount aggregated $0 and $728,350 as of December 31, 2019 and 2018,
respectively. Dividends accrued during the periods ended December 31, 2019 and 2018 were $875,359 and $728,350, respectively.

Pursuant  to  the  Company’s  amended  and  restated  certificate  of  incorporation,  holders  of  the  Series A  Preferred  Stock  have  the  following  methods  of
conversion: (i) automatic conversion into common stock upon the consummation of an IPO at a conversion price of 50% of the IPO price, (ii) automatic
conversion into common stock upon the consummation of a subsequent private placement of securities at a conversion price of 50% of the purchase price
of the securities being sold by the Company approved by the holders of the Series A preferred stock, and (iii) at any time after the issuance date and until
ten calendar days prior to the consummation of an IPO, each holder shall be entitled to convert into common stock at a conversion price of $2.50 per share.

The Series A Preferred Stock automatically converted into 9,571,692 common shares upon completion of the IPO in October 2019, based on the number of
shares of Series A Preferred Stock outstanding as of the date of the IPO. The conversion share calculation was based on the $2.50 initial issue price for the
Series A Preferred Stock plus $1,603,709 of accrued and unpaid dividends and automatically converted into shares of the Company’s common stock using
a stated divisor conversion price equal to 50% of the IPO price to the public which was $5.00 per share. In accordance with relevant accounting literature,
since  the  terms  of  the  conversion  option  did  not  permit  the  Company  to  compute  the  additional  number  of  shares  that  it  would  need  to  issue  upon
conversion  of  the  Series  A  Preferred  when  the  contingent  event  occurred,  the  Company  recorded  the  beneficial  conversion  amount  of  approximately
$23,930,000 as a deemed dividend at the date of the IPO.

2018 Private Placement

In March 13, 2018, the Company entered into a securities purchase agreement with various accredited investors to raise gross proceeds of $14.2 million in
a private placement (the “2018 Private Placement”). On March 22, 2018, the Company completed the 2018 Private Placement, issuing 5,662,000 shares of
its  Series  A  Preferred  Stock.  The  shares  of  the  Series  A  Preferred  Stock  were  sold  for  $2.50  per  share.  The  Company  received  net  proceeds  of
approximately $12.5 million from the 2018 Private Placement, after paying placement agent fees and offering expenses.

The  Series  A  Preferred  Stock  was  accounted  for  under  Section  480-10-S99  —  Distinguishing  Liabilities  from  Equity  (FASB  Accounting  Standards
Codification  480)  as  amended  by  ASU  2009-04  —  for  Redeemable  Equity  Instruments  (“ASU  2009-04”).  Under  ASU  2009-04,  a  redeemable  equity
security is to be classified as temporary equity if it is conditionally redeemable upon the occurrence of an event that is not solely within the control of the
issuer.  While  the  Series  A  Preferred  stock  are  mandatorily  redeemable  21  months  from  the  final  closing  date,  it  also  contains  a  substantive  conversion
option. Therefore, the Company classified the Series A Preferred Stock as temporary equity in the consolidated balance sheet as of December 31, 2018.

In connection with, and upon closing of, the 2018 Private Placement, the Company issued 4,000,000 shares of common stock to LTI in consideration of
LTI’s assignment of the acquired assets consisting of certain patent license rights and other valuable consideration. LTI’s basis in such assets was minimal.

2019 Private Placement

In  May  2019,  the  Company  entered  into  a  securities  purchase  agreement  with  various  accredited  investors  to  raise  gross  proceeds  of  $8.2  million  in  a
private placement (the “2019 Private Placement”), issuing 3,268,000 shares of its Series A Preferred Stock. The shares of the Series A Preferred Stock were
sold for $2.50 per share. The Company received net proceeds of approximately $7.2 million from the 2019 Private Placement, after paying placement agent
fees and offering expenses.

NOTE 8 – WARRANTS

On January 26, 2018 the Company issued a five-year warrant to purchase 400,000 shares of common stock at $0.01 per share to Liquid Patent Advisors,
LLC (“LPA”). The warrant represented consideration for business and strategic development performed during 2018. The fair value of the warrant on the
grant date was estimated using the Black-Scholes-Merton option pricing model with a common stock value of $1.67 per share, a contractual life of 2.5
years, a dividend yield of 0%, a volatility of 102.4% and an assumed risk-free interest rate of 2.19%. The fair value of the warrant was determined to be
$664,224 and is included in general and administrative expenses in the statement of operations.

On March 13, 2018 and March 22, 2018, the Company issued to National Securities Corporation warrants to purchase shares of the Company’s common
stock in an amount equal to 10% of the shares of common stock issuable upon conversion of 5,662,000 shares of the Company’s Series A Preferred Stock.
The warrants represented placement agent compensation in connection with the 2018 Private Placement. The fair value of the warrants on the grant date
was  estimated  using  the  Black-Scholes-Merton  option  pricing  model  with  a  common  stock  value  of  $1.67  per  share,  a  contractual  life  of  2.5  years,  a
dividend yield of 0%, a volatility of 102.4% and an assumed risk-free interest rate of 2.36%. The fair value of the warrants was determined to be $480,485
and is included in general and administrative expenses in the statement of operations. In connection with the conversion of the Series A Preferred Stock as
a result of the IPO, the Company issued additional warrants to purchase 53,679 shares of common stock. The additional warrants were considered offering
costs and netted with the proceeds from the IPO.

In January 2018, the Company’s board of directors approved its 2018 Stock Incentive Plan (“2018 Plan”). The 2018 Plan provides for the grant of non-
qualified  stock  options  and  incentive  stock  options  to  purchase  shares  of  the  Company’s  common  stock,  the  grant  of  restricted  and  unrestricted  share
awards and grant of restricted stock units. The 2018 Plan provides for the issuance of 1,630,000 shares of common stock. All of the Company’s employees
and any subsidiary employees (including officers and directors who are also employees), as well as all of the Company’s nonemployee directors and other
consultants, advisors and other persons who provide services to the Company will be eligible to receive incentive awards under the 2018 Plan.

NOTE 9 – STOCK BASED COMPENSATION, continued

The Company records compensation expense for employee awards with graded vesting using the straight-line method. The Company records compensation
expense for nonemployee awards with graded vesting using the accelerated expense attribution method. The Company recognizes compensation expense
over the requisite service period applicable to each individual award, which generally equals the vesting term. The Company estimates the fair value of
each option award using the Black-Scholes-Merton option pricing model. Forfeitures are recognized when realized.

The  Company  estimated  the  fair  value  of  employee  and  non-employee  stock  options  using  the  Black-Scholes  option  pricing  model.  The  fair  value  of
employee stock options is being amortized on a straight-line basis over the requisite service periods of the respective awards. The fair value of employee
stock options issued was estimated using the following weighted-average assumptions:

The  risk-free  interest  rate  was  obtained  from  U.S.  Treasury  rates  for  the  applicable  periods.  The  Company’s  expected  volatility  was  based  upon  the
historical  volatility  for  industry  peers  and  used  an  average  of  those  volatilities.  The  expected  life  of  the  Company’s  options  was  determined  using  the
simplified  method  as  a  result  of  limited  historical  data  regarding  the  Company’s  activity.  The  dividend  yield  considers  that  the  Company  has  not
historically paid dividends, and does not expect to pay dividends in the foreseeable future.

For grants prior to the IPO, the fair value of the common stock was determined by the board of directors based on a variety of factors, including valuations
prepared by third parties, the Company’s financial position, the status of development efforts within the Company, the current climate in the marketplace
and the prospects of a liquidity event, among others. For grants after the IPO, the Company uses the closing stock price on the date of grant as the fair value
of the common stock.

Period from January 1, 2018 to January 23, 2018 (Predecessor)

NOTE 10 – INCOME TAXES

The Company had no income tax expense due to operating losses incurred for the years ended December 31, 2019 and 2018. The Company accounts for
income taxes in accordance with ASC 740, which requires that the tax benefit of net operating losses, temporary differences and credit carryforwards be
recorded as an asset to the extent that management assesses that realization is “more likely than not.” Realization of the future tax benefits is dependent on
the Company’s ability to generate sufficient taxable income within the carryforward period. Because of the Company’s recent history of operating losses,
management believes that recognition of the deferred tax assets arising from the above-mentioned future tax benefits is currently not likely to be realized
and, accordingly, has provided a full valuation allowance.

The Company’s income tax expense for the periods ended December 31, 2019 and 2018 are summarized below:

As of December 31, 2019 and 2018, the Company had gross federal income tax net operating loss (“NOL”) carryforwards of $13,283,530 and $2,188,203,
respectively, and federal research tax credits of $690,525 and $59,270, respectively.

Utilization of U.S. net operating losses and tax credit carryforwards may be limited by “ownership change” rules, as defined in Sections 382 and 383 of the
Code.  Similar  rules  may  apply  under  state  tax  laws.  The  Company  has  not  conducted  a  study  to-date  to  assess  whether  a  limitation  would  apply  under
Sections 382 and 383 of the Code as and when it starts utilizing its net operating losses and tax credits. The Company will continue to monitor activities in
the future. In the event the Company previously experienced an ownership change, or should experience an ownership change in the future, the amount of
net operating losses and research and development credit carryovers available in any taxable year could be limited and may expire unutilized.

Under  the  Code,  the  NOL  can  be  carried  forward  indefinitely  and  can  be  used  to  offset  up  to  80%  of  taxable  income  for  losses  arising  in  tax  years
beginning after December 31, 2017. In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some
portion  or  all  of  the  deferred  tax  asset  will  be  realized.  The  ultimate  realization  of  deferred  tax  assets  is  dependent  upon  the  Company  attaining  future
taxable income during periods in which those temporary differences become deductible.

Due to the uncertainty surrounding the realization of the benefits of its deferred assets, including NOL carryforwards, the Company has provided a 100%
valuation allowance on its deferred tax assets at December 31, 2019.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

For The Year Ended December 31, 2019, Period From January 24, 2018 to December 31, 2018 and
Period from January 1, 2018 to January 23, 2018 (Predecessor)

NOTE 10 – INCOME TAXES, continued

The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740, Income Taxes. When uncertain tax positions exist, the
Company recognizes the tax benefit of tax positions to the extent that the benefit will more likely than not be realized. The determination as to whether the
tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and
circumstances.  As  of  December  31,  2019,  the  Company  had  a  reserve  for  uncertain  tax  positions  of  $157,814,  and  no  interest  or  penalties  have  been
charged to the Company for the years ended December 31, 2019 and 2018. If incurred, the Company will classify any interest and penalties as a component
of  interest  expense  and  operating  expense,  respectively.  If  recognized,  $157,814  of  the  reserve  for  uncertain  tax  positions  would  favorably  affect  the
Company’s effective tax rate.

A reconciliation of the change in the unrecognized tax positions for the year ended December 31, 2019 is as follows:

Balance at December 31, 2018
Additions for tax positions related to current year
Additions for tax positions related to prior years
Balance at December 31, 2019

Not applicable.

Item 9A. Controls and Procedures

(a)  Evaluation of Disclosure Controls and Procedures.

Our  management,  with  the  participation  of  our  chief  executive  officer  and  chief  financial  officer  evaluated  the  effectiveness  of  our  disclosure
controls  and  procedures  pursuant  to  Rule  13a-15  under  the  Securities  Exchange  Act  of  1934,  as  amended,  or  the  Exchange  Act.  Based  upon  their
evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were not effective as of December
31, 2019 because we have a small number of employees, as a result of our limited operations, which prohibits a segregation of duties. As we grow and
expand  our  operations,  we  intend  to  engage  additional  employees  and  experts  as  needed.  However,  there  can  be  no  assurance  that  our  operations  will
expand.

(b)  Changes in internal control over financial reporting.

There were no changes to our internal control over financial reporting, as defined in Rules 13a-15(f) under the Exchange Act that occurred during
the fiscal quarter ended December 31, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial
reporting.

(c)  Management’s annual report on internal controls over financial reporting.

This annual report does not include a report of management's assessment regarding internal control over financial reporting or an attestation report
of  our  registered  public  accounting  firm  due  to  a  transition  period  established  by  rules  of  the  Securities  and  Exchange  Commission  for  newly  public
companies.

UNDERWRITER WARRANT

286,000 shares of Common Stock

October 29, 2019

This UNDERWRITER WARRANT (this “Warrant”) of TFF Pharmaceuticals, Inc., a corporation duly organized and validly existing under the
laws  of  the  State  of  Delaware  (the  “Company”),  is  being  issued  pursuant  to  that  certain  Underwriting  Agreement,  dated  October  24,  2019  (the
“Underwriting  Agreement”),  between  the  Company  and  National  Securities  Corporation  (the  “Underwriter”)  relating  to  a  firm  commitment  public
offering  (the  “Offering”)  of  4,400,000  shares  of  common  stock,  $0.001  par  value,  of  the  Company  (the  “Common  Stock”)  underwritten  by  the

aggregate Exercise Price of the Warrant Shares being purchased by the Holder; or

by a combination of the foregoing, provided that the combined value of all cash and the Fair Market Value of
any  shares  surrendered  to  the  Company  is  at  least  equal  to  the  aggregate  Exercise  Price  for  the  number  of
Warrant Shares being purchased by the Holder.

Stock for the five (5) trading days immediately preceding the applicable exercise herein as officially reported by the principal securities exchange on which
the  Common  Stock  is  then  listed  or  admitted  to  trading,  or,  if  the  Common  Stock  is  not  listed  or  admitted  to  trading  on  any  securities  exchange  as
determined in good faith by resolution of the Board of Directors of the Company, based on the best information available to it.

To illustrate a cashless exercise of this Warrant under Section 3.1 (c)(ii) (or for a portion thereof for which cashless exercise treatment is requested

as contemplated by Section 3.1(c)(iii) hereof), the calculation of such exercise shall be as follows:

X = Y (A-B)/A

where:

X =

the number of Warrant Shares to be issued to the Holder (rounded to the nearest whole share).

Y =

the number of Warrant Shares with respect to which this Warrant is being exercised.

A =

the Fair Market Value of the Common Stock.

B =

the Exercise Price.

(d) For purposes of Rule 144 and sub-section (d)(3)(ii) thereof, it is intended, understood, and acknowledged that the Common
Stock issuable upon exercise of this Warrant in a cashless exercise transaction as described in Section 3.1(c) above shall be deemed to have been acquired
at the time this Warrant was issued. Moreover, it is intended, understood, and acknowledged that the holding period for the Common Stock issuable upon
exercise of this Warrant in a cashless exercise transaction as described in Section 3.1(c) above shall be deemed to have commenced on the date this Warrant
was issued.

3.2 When  Exercise  Effective.  Each  exercise  of  this  Warrant  shall  be  deemed  to  have  been  effected  immediately  prior  to  the  close  of
business on the Business Day on which this Warrant shall have been duly surrendered to the Company as provided in Sections 3.1 and 12 hereof, and, at
such time, the Holder in whose name any certificate or certificates for Warrant Shares shall be issuable upon exercise as provided in Section 3.3 hereof
shall be deemed to have become the holder or holders of record thereof of the number of Warrant Shares purchased upon exercise of this Warrant.

3.3 Delivery of Common Stock Certificates and New Warrant. As soon as reasonably practicable after each exercise of this Warrant, in
whole or in part, and in any event within three (3) Business Days thereafter, the Company, at its expense (including the payment by it of any applicable
issue taxes), will cause to be issued in the name of and delivered to the Holder hereof or, subject to Sections 9 and 10 hereof, as the Holder (upon payment
by the Holder of any applicable transfer taxes) may direct:

issued, fully paid and non-assessable Warrant Shares to which the Holder shall be entitled upon exercise; and

(a)  a  certificate  or  certificates  (with  appropriate  restrictive  legends,  as  applicable)  for  the  number  of  duly  authorized,  validly

(b) in case exercise is in part only, a new Warrant document of like tenor, dated the date hereof, for the remaining number of
Warrant  Shares  issuable  upon  exercise  of  this  Warrant  after  giving  effect  to  the  partial  exercise  of  this  Warrant  (including  the  delivery  of  any  Warrant
Shares as payment of the Exercise Price for such partial exercise of this Warrant).

4. Certain Adjustments. For so long as this Warrant is outstanding:

4.1 Mergers or Consolidations. If at any time after the date hereof there shall be a capital reorganization (other than a combination or
subdivision of Common Stock otherwise provided for herein) resulting in a reclassification to or change in the terms of securities issuable upon exercise of
this Warrant (a “Reorganization”), or a merger or consolidation of the Company with another corporation, association, partnership, organization, business,
individual, government or political subdivision thereof or a governmental agency (a “Person” or the “Persons”) (other than a merger with another Person
in  which  the  Company  is  a  continuing  corporation  and  which  does  not  result  in  any  reclassification  or  change  in  the  terms  of  securities  issuable  upon
exercise of this Warrant or a merger effected exclusively for the purpose of changing the domicile of the Company) (a “Merger”), then, as a part of such
Reorganization or Merger, lawful provision and adjustment shall be made so that the Holder shall thereafter be entitled to receive, upon exercise of this
Warrant, the number of shares of stock or any other equity or debt securities or property receivable upon such Reorganization or Merger by a holder of the
number of shares of Common Stock which might have been purchased upon exercise of this Warrant immediately prior to such Reorganization or Merger.
In any such case, appropriate adjustment shall be made in the application of the provisions of this Warrant with respect to the rights and interests of the
Holder after the Reorganization or Merger to the end that the provisions of this Warrant (including adjustment of the Exercise Price then in effect and the
number of Warrant Shares) shall be applicable after that event, as near as reasonably may be, in relation to any shares of stock, securities, property or other
assets thereafter deliverable upon exercise of this Warrant. The provisions of this Section 4.1 shall similarly apply to successive Reorganizations and/or
Mergers.

4.2 Splits and Subdivisions; Dividends. In the event the Company should at any time or from time to time effectuate a split or subdivision
of the outstanding shares of Common Stock or pay a dividend in or make a distribution payable in additional shares of Common Stock or other securities,
or rights convertible into, or entitling the holder thereof to receive, directly or indirectly, additional shares of Common Stock (hereinafter referred to as
“Common  Stock  Equivalents”)  without  payment  of  any  consideration  by  such  holder  for  the  additional  shares  of  Common  Stock  or  Common  Stock
Equivalents (including the additional shares of Common Stock issuable upon conversion or exercise thereof), then, as of the applicable record date (or the
date of such distribution, split or subdivision if no record date is fixed), the per share Exercise Price shall be appropriately decreased and the number of
Warrant  Shares  shall  be  appropriately  increased  in  proportion  to  such  increase  (or  potential  increase)  of  outstanding  shares;  provided,  however,  that  no
adjustment shall be made in the event the split, subdivision, dividend or distribution is not effectuated.

4

 
 
 
 
 
 
 
 
 
 
4.3 Combination of Shares. If the number of shares of Common Stock outstanding at any time after the date hereof is decreased by a
combination of the outstanding shares of Common Stock, the per share Exercise Price shall be appropriately increased and the number of shares of Warrant
Shares shall be appropriately decreased in proportion to such decrease in outstanding shares.

4.4 Adjustments for Other Distributions.  In  the  event  the  Company  shall  declare  a  distribution  payable  in  securities  of  other  Persons,
evidences of indebtedness issued by the Company or other Persons, assets (excluding cash dividends or distributions to the holders of Common Stock paid
out of current or retained earnings and declared by the Company’s Board of Directors) or options or rights not referred to in Sections 4.2 or 4.3 then, in
each  such  case  for  the  purpose  of  this  Section  4.4,  upon  exercise  of  this  Warrant,  the  Holder  shall  be  entitled  to  a  proportionate  share  of  any  such
distribution as though the Holder was the actual record holder of the number of Warrant Shares as of the record date fixed for the determination of the
holders of Common Stock of the Company entitled to receive such distribution.

5. No Impairment.  The  Company  will  not,  by  amendment  of  its  certificate  of  incorporation  or  by-laws  or  through  any  consolidation,  merger,
reorganization, transfer of assets, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all of the terms and in the taking of all actions necessary or
appropriate in order to protect the rights of the Holder against impairment.

6. Notice as to Adjustments. With respect to each adjustment pursuant to Section 4 of this Warrant, the Company, at its expense, will promptly
compute the adjustment or re-adjustment in accordance with the terms of this Warrant and furnish the Holder with a certificate certified and confirmed by
the  Secretary  or  Chief  Financial  Officer  of  the  Company  setting  forth,  in  reasonable  detail,  the  event  requiring  the  adjustment  or  re-adjustment  and  the
amount of such adjustment or re-adjustment, the method of calculation thereof and the facts upon which the adjustment or re-adjustment is based, and the
Exercise Price and the number of Warrant Shares or other securities purchasable hereunder after giving effect to such adjustment or re-adjustment, which
report shall be mailed by first class mail, postage prepaid to the Holder.

7. Reservation of Shares. The Company shall, solely for the purpose of effecting the exercise of this Warrant, at all times during the term of this
Warrant, reserve and keep available out of its authorized shares of Common Stock, free from all taxes, liens and charges with respect to the issue thereof
and not subject to preemptive rights of shareholders of the Company, such number of its shares of Common Stock as shall from time to time be sufficient to
effect in full the exercise of this Warrant. If at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect in
full the exercise of this Warrant, in addition to such other remedies as shall be available to Holder, the Company will promptly take such corporate action as
may, in the opinion of its counsel, be necessary to increase the number of authorized but unissued shares of Common Stock to such number of shares as
shall be sufficient for such purposes, including without limitation, using its Reasonable Commercial Efforts (as defined in Section 14 hereof) to obtain the
requisite shareholder approval necessary to increase the number of authorized shares of Common Stock. The Company hereby represents and warrants that
all shares of Common Stock issuable upon proper exercise of this Warrant shall be duly authorized and, when issued and paid for upon proper exercise,
shall be validly issued, fully paid and nonassessable.

8. Registration and Listing.

8.1 Definition  of  Registrable  Securities;  Majority.  As  used  herein,  the  term  “Registrable  Securities”  means  any  shares  of  Common
Stock issuable upon the exercise of this Warrant until the date (if any) on which such shares shall have been transferred or exchanged and new certificates
for  them  not  bearing  a  legend  restricting  further  transfer  shall  have  been  delivered  by  the  Company  and  subsequent  disposition  of  the  shares  shall  not
require  registration  or  qualification  under  the  Securities  Act  or  any  similar  state  law  then  in  force.  For  purposes  of  this  Warrant,  the  term  “Majority
Holders” shall mean in excess of fifty percent (50%) of the then outstanding Warrant Shares.

8.2 Demand Registration Rights.

(a) The Company, upon written demand (“Demand Notice”) of the Majority Holders, agrees to register on one occasion all of
the Registrable Securities (a “Demand Right”).  On  such  occasion,  the  Company  will  file  a  registration  statement  or  a  post-effective  amendment  to  the
Registration Statement covering the Registrable Securities within forty-five (45) days after receipt of a Demand Notice and use its Reasonable Commercial
Efforts  to  have  such  registration  statement  or  post-effective  amendment  declared  effective  as  soon  as  possible  thereafter;  provided,  however,  that  the
Company  shall  not  be  required  to  comply  with  a  Demand  Notice  if  the  Company  has  filed  a  registration  statement  with  respect  to  which  the  Holder  is
entitled to piggyback registration rights pursuant to Section 8.3 hereof and either: (i) the Holder has elected to participate in the offering covered by such
registration  statement  or  (ii)  if  such  registration  statement  relates  to  an  underwritten  primary  offering  of  securities  of  the  Company,  until  the  offering
covered by such registration statement has been withdrawn or until thirty (30) days after such offering is consummated. The demand for registration may be
made at any time during a period of four years beginning one (1) year from the Base Date. The Company covenants and agrees to give written notice of its
receipt of any Demand Notice to all other registered Holders of the Warrants and/or the Registrable Securities within ten days from the date of the receipt
of any such Demand Notice.

(b) The Company shall bear all fees and expenses attendant to registering the Registrable Securities pursuant to Section 8.2(a),
but  the  Holders  shall  pay  any  and  all  underwriting  commissions  and  the  expenses  of  any  legal  counsel  selected  by  the  Holders  to  represent  them  in
connection with the sale of the Registrable Securities. The Company agrees to use its Reasonable Commercial Efforts to qualify or register the Registrable
Securities  in  such  states  as  are  reasonably  requested  by  the  Majority  Holder(s);  provided,  however,  that  in  no  event  shall  the  Company  be  required  to
register the Registrable Securities in a state in which such registration would cause (i) the Company to be obligated to register, license or qualify to do
business in such state, submit to general service of process in such state or would subject the Company to taxation as a foreign corporation doing business
in such jurisdiction or (ii) the principal stockholders of the Company to be obligated to escrow their shares of capital stock of the Company. The Company
shall cause any registration statement or post-effective amendment filed pursuant to the Demand Right granted under Section 8.2(a) to remain effective for
a period of nine consecutive months from the effective date of such registration statement or post-effective amendment. The Holders shall only use the
prospectuses provided by the Company to sell the Registrable Securities covered by such registration statement, and will immediately cease to use any
prospectus furnished by the Company if the Company advises the Holder that such prospectus may no longer be used due to a material misstatement or
omission.

6

 
 
 
 
 
 
 
 
 
8.3 Incidental Registration Rights.

(a) If the Company, for a period of six (6) years commencing one (1) year after the Base Date, proposes to register any of its
securities  under  the  Securities  Act  (other  than  in  connection  with  a  transaction  contemplated  by  Rule  145(a)  promulgated  under  the  Securities Act  or
pursuant to registration on Form S-4 or S-8 or any successor forms) whether for its own account or for the account of any holder or holders of its shares
other than Registrable Securities (any shares of such holder or holders (but not those of the Company and not Registrable Securities) with respect to any
registration are referred to herein as, “Other Shares”), the Company shall at each such time give prompt (but not less than thirty (30) days prior to the
anticipated effectiveness thereof) written notice to the holders of Registrable Securities of its intention to do so. The holders of Registrable Securities shall
exercise  the  “piggy-back”  rights  provided  herein  by  giving  written  notice  within  ten  (10)  days  after  the  receipt  of  any  such  notice  (which  request  shall
specify the Registrable Securities intended to be disposed of by such holder). Except as set forth in Section 8.3(b), the Company will use its Reasonable
Commercial  Efforts  to  effect  the  registration  under  the  Securities Act  of  all  of  the  Registrable  Securities  which  the  Company  has  been  so  requested  to
register by such holder, to the extent required to permit the disposition of the Registrable Securities so to be registered, by inclusion of such Registrable
Securities  in  the  registration  statement  which  covers  the  securities  which  the  Company  proposes  to  register.  The  Company  will  pay  all  Registration
Expenses in connection with each registration of Registrable Securities pursuant to this Section 8.3.

(b) If the Company at any time proposes to register any of its securities under the Securities Act as contemplated by this Section
8.3 and such securities are to be distributed by or through one or more underwriters, the Company will, if requested by a holder of Registrable Securities,
use  its  Reasonable  Commercial  Efforts  to  arrange  for  such  underwriters  to  include  all  the  Registrable  Securities  to  be  offered  and  sold  by  such  holder
among  the  securities  to  be  distributed  by  such  underwriters,  provided  that  if  the  managing  underwriter  of  such  underwritten  offering  shall  inform  the
Company by letter of its belief that inclusion in such registration statement and/or distribution of all or a specified number of such securities proposed to be
distributed by such underwriters would interfere with the successful marketing of the securities being distributed by such underwriters (such letter to state
the basis of such belief and the approximate number of such Registrable Securities, such Other Shares and shares held by the Company proposed so to be
registered  which  may  be  distributed  without  such  effect),  then  the  Company  may,  upon  written  notice  to  such  holder,  the  other  holders  of  Registrable
Securities, and holders of such Other Shares, reduce pro rata in accordance with the number of shares of Common Stock desired to be included in such
registration statement and/or distribution (if and to the extent stated by such managing underwriter to be necessary to eliminate such effect) the number of
such  Registrable  Securities  and  Other  Shares  the  registration  and/or  distribution  of  which  shall  have  been  requested  by  each  holder  thereof  so  that  the
resulting aggregate number of such Registrable Securities and Other Shares so included in such registration and/or distribution, together with the number of
securities  to  be  included  in  such  registration  and/or  distribution  for  the  account  of  the  Company,  shall  be  equal  to  the  number  of  shares  stated  in  such
managing underwriter’s letter.

7

 
 
 
 
 
 
 
8.4 Registration Procedures. Whenever the holders of Registrable Securities have properly requested that any Registrable Securities be
registered pursuant to the terms of this Warrant, the Company shall use its Reasonable Commercial Efforts to effect the registration for the sale of such
Registrable Securities in accordance with the intended method of disposition thereof, and pursuant thereto the Company shall as expeditiously as possible:

Commercial Efforts to cause such registration statement to become effective;

(a)  prepare  and  file  with  the  SEC  a  registration  statement  with  respect  to  such  Registrable  Securities  and  use  its  Reasonable

(b) notify such holders of the effectiveness of each registration statement filed hereunder and prepare and file with the SEC such
amendments  and  supplements  to  such  registration  statement  and  the  prospectus  used  in  connection  therewith  as  may  be  necessary  to  (i)  keep  such
registration statement effective and the prospectus included therein usable for a period commencing on the date that such registration statement is initially
declared effective by the SEC and ending on the earlier of (A) the date when all Registrable Securities covered by such registration statement have been
sold pursuant to the registration statement or cease to be Registrable Securities, or (B) nine months from the effective date of the registration statement; and
(ii)  comply  with  the  provisions  of  the  Securities  Act  with  respect  to  the  disposition  of  all  securities  covered  by  such  registration  statement  during  such
period in accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement;

(c) furnish to such holders such number of copies of such registration statement, each amendment and supplement thereto, the
prospectus included in such registration statement (including each preliminary prospectus) and such other documents as such seller may reasonably request
in order to facilitate the disposition of the Registrable Securities owned by such holders;

(d) use its Reasonable Commercial Efforts to register or qualify such Registrable Securities under such other securities or blue
sky laws of such jurisdictions as such holders reasonably request and do any and all other acts and things which may be reasonably necessary or advisable
to enable such holders to consummate the disposition in such jurisdictions of the Registrable Securities owned by such holders; provided, however, that the
Company shall not be required to: (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this
subparagraph; (ii) subject itself to taxation in any such jurisdiction; or (iii) consent to general service of process in any such jurisdiction;

8

 
 
 
 
 
 
 
 
 
(e) notify such holders, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the
happening of any event as a result of which the prospectus included in such registration statement contains an untrue statement of a material fact or omits
any material fact necessary to make the statements therein, in light of the circumstances in which they are made, not materially misleading, and, at the
reasonable  request  of  such  holders,  the  Company  shall  prepare  a  supplement  or  amendment  to  such  prospectus  so  that,  as  thereafter  delivered  to  the
purchasers  of  such  Registrable  Securities,  such  prospectus  shall  not  contain  an  untrue  statement  of  a  material  fact  or  omit  to  state  any  material  fact
necessary to make the statements therein, in light of the circumstances in which they are made, not materially misleading;

statement;

(f) provide a transfer agent and registrar for all such Registrable Securities not later than the effective date of such registration

(g) make available for inspection by any underwriter participating in any disposition pursuant to such registration statement, and
any attorney, accountant or other agent retained by any such underwriter, all financial and other records, pertinent corporate documents and properties of
the  Company,  and  cause  the  Company’s  officers,  directors,  managers,  employees  and  independent  accountants  to  supply  all  information  reasonably
requested by any such underwriter, attorney, accountant or agent in connection with such registration statement;

(h) otherwise use its Reasonable Commercial Efforts to comply with all applicable rules and regulations of the SEC, and make
available  to  its  security  holders,  as  soon  as  reasonably  practicable,  an  earnings  statement  of  the  Company,  which  earnings  statement  shall  satisfy  the
provisions of Section 11(a) of the Securities Act and, at the option of the Company, Rule 158 thereunder;

(i)  in  the  event  of  the  issuance  of  any  stop  order  suspending  the  effectiveness  of  a  registration  statement,  or  of  any  order
suspending  or  preventing  the  use  of  any  related  prospectus  or  suspending  the  qualification  of  any  Registrable  Securities  included  in  such  registration
statement for sale in any jurisdiction, the Company shall use its Reasonable Commercial Efforts promptly to obtain the withdrawal of such order; and

(j) if the offering is underwritten, use its Reasonable Commercial Efforts to furnish on the date that Registrable Securities are
delivered to the underwriters for sale pursuant to such registration, an opinion dated such date of counsel representing the Company for the purposes of
such registration, addressed to the underwriters covering such issues as are reasonably required by such underwriters.

8.5 Listing. The Company shall secure the listing of the Common Stock underlying this Warrant upon each national securities exchange
or automated quotation system upon which shares of Common Stock are then listed or quoted (subject to official notice of issuance) and shall maintain
such listing of shares of Common Stock. The Company shall at all times comply in all material respects with the Company’s reporting, filing and other
obligations under the by-laws or rules of The NASDAQ Stock Market (or such other national securities exchange or market on which the Common Stock
may then be listed, as applicable).

9

 
 
 
 
 
 
 
 
 
 
 
8.6 Expenses. The Company shall pay all Registration Expenses relating to the registration and listing obligations set forth in this Section
8. For purposes of this Warrant, the term “Registration Expenses” means: (a) all registration, filing and FINRA fees, (b) all reasonable fees and expenses
of complying with securities or blue sky laws, (c) all word processing, duplicating and printing expenses, (d) the fees and disbursements of counsel for the
Company and of its independent public accountants, including the expenses of any special audits or “cold comfort” letters required by or incident to such
performance  and  compliance,  (e)  premiums  and  other  costs  of  policies  of  insurance  (if  any)  against  liabilities  arising  out  of  the  public  offering  of  the
Registrable Securities being registered if the Company desires such insurance, if any, and (f) fees and disbursements of one counsel for the selling holders
of Registrable Securities; provided however, that, in any case where Registration Expenses are not to be borne by the Company, such expenses shall not
include (and such expenses shall be borne by the Company): (i) salaries of Company personnel or general overhead expenses of the Company, (ii) auditing
fees, or (iii) other expenses for the preparation of financial statements or other data, to the extent that any of the foregoing either is normally prepared by
the Company in the ordinary course of its business or would have been incurred by the Company had no public offering taken place. Registration Expenses
shall not include any underwriting discounts and commissions which may be incurred in the sale of any Registrable Securities and transfer taxes of the
selling holders of Registrable Securities.

8.7 Information Provided by Holders. Any holder of Registrable Securities included in any registration shall furnish to the Company such
information  as  the  Company  may  reasonably  request  in  writing,  including,  but  not  limited  to,  a  completed  and  executed  questionnaire  requesting
information customarily sought of selling security holders, to enable the Company to comply with the provisions hereof in connection with any registration
referred to in this Warrant. The Holder agrees to suspend all sales of Registrable Securities pursuant to a registration statement filed under Section 8.3 in
the event the Company notifies Holder pursuant to Section 8.4(e) that the prospectus relating thereto is no longer current and will not resume sales under
such registration statement until advised by the Company that the prospectus has been appropriately supplemented or amended.

8.8 FINRA Public Offering System Filings. In the event that a registration statement covering the Registrable Securities is filed, within
one (1) Business Day of the filing of such registration statement, the Company will prepare and file the selling stockholder resale offering described in such
registration statement for review by FINRA via the FINRA’s Public Offering System filing system (“Public Offering System Filing”) for the purpose of
having the prospectus contained within such registration statement treated as a “base prospectus” in connection with such resale offering. The Company
will use its Reasonable Commercial Efforts to have the Public Offering System Filing approved by FINRA within thirty (30) days of such filing date. The
Company shall bear all expenses of the Public Offering System Filing, including fees and expenses of one counsel or other advisor to the Holder. In all
circumstances, the Company shall pay for all FINRA filing fees associated with the Public Offering System Filing.

8.9 Effectiveness Period. The Company shall use its Reasonable Commercial Efforts to keep each registration statement contemplated
hereunder  continuously  effective  under  the  Securities  Act  until  the  date  which  is  the  earlier  date  of  when  (i)  all  Registrable  Securities  covered  by  such
Registration Statement have been sold, (ii) all Registrable Securities covered by such Registration Statement may be sold immediately without registration
under  the  Securities  Act  and  without  volume  restrictions  pursuant  to  Rule  144  under  the  Securities  Act,  as  determined  by  the  counsel  to  the  Company
pursuant  to  a  written  opinion  letter  to  such  effect,  addressed  and  reasonably  acceptable  to  the  Company’s  transfer  agent  and  the  affected  holders  of
Registrable Securities, or (iii) nine months from the effective date of such registration statement.

10

 
 
 
 
 
 
 
 
8.10 Net Cash Settlement. Notwithstanding anything herein to the contrary, in no event will the Holder hereof be entitled to receive a net-
cash settlement as liquidated damages in lieu of physical settlement in shares of Common Stock, regardless of whether the Common Stock underlying this
Warrant is registered pursuant to an effective registration statement; provided, however, that the foregoing will not preclude the Holder from seeking other
remedies at law or equity for breaches by the Company of its registration obligations hereunder.

9. Restrictions on Transfer.

9.1 Restrictive Legends. This Warrant and each Warrant issued upon transfer or in substitution for this Warrant pursuant to Section 10
hereof, each certificate for Common Stock issued upon the exercise of the Warrant and each certificate issued upon the transfer of any such Common Stock
shall  be  transferable  only  upon  satisfaction  of  the  conditions  specified  in  this  Section  9.  Each  of  the  foregoing  securities  shall  be  stamped  or  otherwise
imprinted  with  a  legend  reflecting  the  restrictions  on  transfer  set  forth  herein  and  any  restrictions  required  under  the  Securities  Act  or  other  applicable
securities laws.

9.2 Notice of Proposed Transfer. Prior to any transfer of any securities which are not registered under an effective registration statement
under the Securities Act (“Restricted Securities”), which transfer may only occur if there is an exemption from the registration provisions of the Securities
Act and all other applicable securities laws, the Holder will give written notice to the Company of the Holder’s intention to effect a transfer (and shall
describe the manner and circumstances of the proposed transfer). The following provisions shall apply to any proposed transfer of Restricted Securities:

(i)  If  in  the  opinion  of  counsel  for  the  Holder  reasonably  satisfactory  to  the  Company  the  proposed  transfer  may  be  effected
without  registration  of  the  Restricted  Securities  under  the  Securities  Act  (which  opinion  shall  state  in  detail  the  basis  of  the  legal  conclusions  reached
therein), the Holder shall thereupon be entitled to transfer the Restricted Securities in accordance with the terms of the notice delivered by the Holder to the
Company. Each certificate representing the Restricted Securities issued upon or in connection with any transfer shall bear the restrictive legends required
by Section 9.1 hereof.

(ii) If the opinion called for in (i) above is not delivered, the Holder shall not be entitled to transfer the Restricted Securities until
either:  (x)  receipt  by  the  Company  of  a  further  notice  from  such  Holder  pursuant  to  the  foregoing  provisions  of  this  Section  9.2  and  fulfillment  of  the
provisions of clause (i) above, or (y) such Restricted Securities have been effectively registered under the Securities Act.

11

 
 
 
 
 
 
 
 
 
 
9.3 Certain Other Transfer Restrictions. Notwithstanding any other provision of this Warrant: (i) prior to the Exercise Date, this Warrant
or the Restricted Securities thereunder may only be transferred or assigned to the persons permitted under FINRA Rule 5110(g), and (ii) subject at all times
to FINRA Rule 5110(g), no opinion of counsel shall be necessary for a transfer of Restricted Securities by the holder thereof to any Person employed by or
owning equity in the Holder, if the transferee agrees in writing to be subject to the terms hereof to the same extent as if the transferee were the original
purchaser hereof and such transfer is permitted under applicable securities laws.

9.4 Termination of Restrictions. Except as set forth in Section 9.3 hereof and subject at all times to FINRA Rule 5110(g), the restrictions
imposed by this Section 9 upon the transferability of Restricted Securities shall cease and terminate as to any particular Restricted Securities: (a) which
shall  have  been  effectively  registered  under  the  Securities  Act,  or  (b)  when,  in  the  opinion  of  counsel  for  the  Company,  such  restrictions  are  no  longer
required  in  order  to  insure  compliance  with  the  Securities  Act  or  Section  10  hereof.  Whenever  such  restrictions  shall  cease  and  terminate  as  to  any
Restricted Securities, the Holder thereof shall be entitled to receive from the Company, without expense (other than applicable transfer taxes, if any), new
securities of like tenor not bearing the applicable legends required by Section 9.1 hereof.

10. Ownership, Transfer, Sale and Substitution of Warrant.

10.1  Ownership  of  Warrant.  The  Company  may  treat  any  Person  in  whose  name  this  Warrant  is  registered  in  the  Warrant  Register
maintained pursuant to Section 10.2(b) hereof as the owner and holder thereof for all purposes, notwithstanding any notice to the contrary, except that, if

11. Indemnification. In connection with any Registration Statement or any other disclosure document pursuant to which securities of the Company
are sold, the Company will, and hereby does, jointly and severally, indemnify and hold harmless the Holder, its directors, officers, fiduciaries, and agents

under  the  Securities  Act,  any  other  securities  or  other  laws  of  any  jurisdiction,  common  law  or  otherwise,  insofar  as  such  losses,  claims,  damages  or
liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (1) any untrue statement or alleged untrue statement of any material
fact contained or incorporated by reference in any Registration Statement under the Securities Act, any preliminary prospectus or final prospectus included

liability, action or proceeding, provided, however, the Company shall not be liable to any Covered Person in any such case to the extent that any such loss,
claim, damage, liability, action or proceeding is determined, by a final, non-appealable judgment by a court or arbitral tribunal of competent jurisdiction, to
have arisen out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement,
any such preliminary prospectus, final prospectus, amendment or supplement, any document incorporated by reference or other such disclosure document
in  reliance  upon  and  in  conformity  with  written  information  furnished  to  the  Company  through  an  instrument  duly  executed  by  such  Covered  Person

12. No Rights or Liabilities as Stockholder. No Holder shall be entitled to vote or be deemed the holder of any equity securities which may at any
time  be  issuable  on  the  exercise  hereof,  nor  shall  anything  contained  herein  be  construed  to  confer  upon  the  Holder,  as  such,  any  of  the  rights  of  a
stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give
or  withhold  consent  to  any  corporate  action  (whether  upon  any  recapitalization,  issuance  of  stock,  reclassification  of  stock,  change  of  par  value,
consolidation, merger, conveyance, or otherwise) or to receive notice of meetings until the Warrant shall have been exercised and the shares of Common
Stock purchasable upon the exercise hereof shall have become deliverable, as provided herein.

14. Payment of Taxes. The Company will pay all documentary stamp taxes attributable to the issuance of shares of Common Stock underlying this
Warrant upon exercise of this Warrant; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any

by  the  party  against  which  enforcement  of  the  change,  waiver,  discharge  or  termination  is  sought.  This  Warrant  shall  be  construed  and  enforced  in

and provisions of this Warrant shall not in any way be affected or impaired thereby, and the parties will attempt in good faith to agree upon a valid and
enforceable provision which shall be a commercially reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this

UNDERWRITER WARRANT

31,155 shares of Common Stock

November 20, 2019

This UNDERWRITER WARRANT (this “Warrant”) of TFF Pharmaceuticals, Inc., a corporation duly organized and validly existing under the
laws  of  the  State  of  Delaware  (the  “Company”),  is  being  issued  pursuant  to  that  certain  Underwriting  Agreement,  dated  October  24,  2019  (the
“Underwriting Agreement”), between the Company and National Securities Corporation (the “Underwriter”) relating to the Underwriter’s exercise of its
over-allotment  option  as  part  of  a  firm  commitment  public  offering  (the  “Offering”)  of  4,400,000  shares  of  common  stock,  $0.001  par  value,  of  the
Company (the “Common Stock”) underwritten by the Underwriter.

FOR VALUE RECEIVED, the Company hereby grants to National Securities Corporation and its permitted successors and assigns (collectively,
the  “Holder”)  the  right  to  purchase  from  the  Company  up  to  31,155  shares  of  Common  Stock  (such  shares  underlying  this  Warrant,  the  “Warrant
Shares”),  at  a  per  share  purchase  price  equal  to  $6.25  (the  “Exercise Price”), subject  to  the  terms,  conditions  and  adjustments  set  forth  below  in  this
Warrant.

1. Date of Warrant Exercise. This Warrant shall become exercisable three hundred sixty-five (365) days after the Base Date (the “Exercise Date”).
As  used  in  this  Warrant,  the  term  “Base  Date”  shall  mean  October  24,  2019  (the  effective  date  of  the  registration  statement).  Except  as  permitted  by
applicable  rules  of  the  Financial  Industry  Regulatory  Authority,  Inc.  (“FINRA”),  this  Warrant  and  the  underlying  Warrant  Shares  shall  not  be  sold,
transferred, assigned, pledged or hypothecated prior to the date that is three hundred sixty-five (365) days immediately following the Base Date pursuant to
FINRA Rule 5110(g)(1), except as permitted under FINRA Rule 5110(g)(2).

 
 
 
 
 
 
 
 
2. Expiration of Warrant. This Warrant shall expire on the five (5) year anniversary of the Base Date (the “Expiration Date”).

3. Exercise of Warrant. This Warrant shall be exercisable pursuant to the terms of this Section 3.

3.1 Manner of Exercise.

(a)  This Warrant  may  only  be  exercised  by  the  Holder  hereof  on  or  after  the  Exercise  Date  and  on  or  prior  to  the  Expiration
Date, in accordance with the terms and conditions hereof, in whole or in part (but not as to fractional shares) with respect to any portion of this Warrant,
during the Company’s normal business hours on any day other than a Saturday or a Sunday or a day on which commercial banking institutions in New
York, New York are authorized by law to be closed (a “Business Day”), by surrender of this Warrant to the Company at its office maintained pursuant to
Section 10.2(a) hereof, accompanied by a written exercise notice in the form attached as Exhibit A to this Warrant (or a reasonable facsimile thereof) duly
executed  by  the  Holder,  together  with  the  payment  of  the  aggregate  Exercise  Price  for  the  number  of  Warrant  Shares  purchased  upon  exercise  of  this
Warrant. Upon surrender of this Warrant, the Company shall cancel this Warrant document and shall, in the event of partial exercise, replace it with a new
Warrant document in accordance with Section 3.3.

(b) Except as provided for in Section 3.1(c) below, each exercise of this Warrant must be accompanied by payment in full of the
aggregate Exercise Price in cash by check or wire transfer in immediately available funds for the number of Warrant Shares being purchased by the Holder
upon such exercise.

Holder, be paid in full or in part on a “cashless basis” at the election of the Holder:

(c)  The  aggregate  Exercise  Price  for  the  number  of  Warrant  Shares  being  purchased  may  also,  in  the  sole  discretion  of  the

(i)

(ii)

(iii)

in the form of Common Stock owned by the Holder (based on the Fair Market Value (as defined below) of
such Common Stock on the date of exercise);

in  the  form  of  Warrant  Shares  withheld  by  the  Company  from  the  Warrant  Shares  otherwise  to  be  received
upon  exercise  of  this  Warrant  having  an  aggregate  Fair  Market  Value  on  the  date  of  exercise  equal  to  the
aggregate Exercise Price of the Warrant Shares being purchased by the Holder; or

by a combination of the foregoing, provided that the combined value of all cash and the Fair Market Value of
any  shares  surrendered  to  the  Company  is  at  least  equal  to  the  aggregate  Exercise  Price  for  the  number  of
Warrant Shares being purchased by the Holder.

2

 
 
 
 
 
 
 
 
 
 
 
 
 
For purposes of this Warrant, the term “Fair Market Value” means with respect to a particular date, the average closing price of the Common
Stock for the five (5) trading days immediately preceding the applicable exercise herein as officially reported by the principal securities exchange on which
the  Common  Stock  is  then  listed  or  admitted  to  trading,  or,  if  the  Common  Stock  is  not  listed  or  admitted  to  trading  on  any  securities  exchange  as
determined in good faith by resolution of the Board of Directors of the Company, based on the best information available to it.

To illustrate a cashless exercise of this Warrant under Section 3.1 (c)(ii) (or for a portion thereof for which cashless exercise treatment is requested

as contemplated by Section 3.1(c)(iii) hereof), the calculation of such exercise shall be as follows:

X = Y (A-B)/A

where:

X =

the number of Warrant Shares to be issued to the Holder (rounded to the nearest whole share).

Y = the number of Warrant Shares with respect to which this Warrant is being exercised.

A = the Fair Market Value of the Common Stock.

B = the Exercise Price.

(d) For purposes of Rule 144 and sub-section (d)(3)(ii) thereof, it is intended, understood, and acknowledged that the Common
Stock issuable upon exercise of this Warrant in a cashless exercise transaction as described in Section 3.1(c) above shall be deemed to have been acquired
at the time this Warrant was issued. Moreover, it is intended, understood, and acknowledged that the holding period for the Common Stock issuable upon
exercise of this Warrant in a cashless exercise transaction as described in Section 3.1(c) above shall be deemed to have commenced on the date this Warrant
was issued.

3.2 When  Exercise  Effective.  Each  exercise  of  this  Warrant  shall  be  deemed  to  have  been  effected  immediately  prior  to  the  close  of
business on the Business Day on which this Warrant shall have been duly surrendered to the Company as provided in Sections 3.1 and 12 hereof, and, at
such time, the Holder in whose name any certificate or certificates for Warrant Shares shall be issuable upon exercise as provided in Section 3.3 hereof
shall be deemed to have become the holder or holders of record thereof of the number of Warrant Shares purchased upon exercise of this Warrant.

3

 
 
 
 
 
 
 
 
 
 
 
 
 
 
3.3 Delivery of Common Stock Certificates and New Warrant. As soon as reasonably practicable after each exercise of this Warrant, in
whole or in part, and in any event within three (3) Business Days thereafter, the Company, at its expense (including the payment by it of any applicable
issue taxes), will cause to be issued in the name of and delivered to the Holder hereof or, subject to Sections 9 and 10 hereof, as the Holder (upon payment
by the Holder of any applicable transfer taxes) may direct:

issued, fully paid and non-assessable Warrant Shares to which the Holder shall be entitled upon exercise; and

(a)  a  certificate  or  certificates  (with  appropriate  restrictive  legends,  as  applicable)  for  the  number  of  duly  authorized,  validly

(b) in case exercise is in part only, a new Warrant document of like tenor, dated the date hereof, for the remaining number of
Warrant  Shares  issuable  upon  exercise  of  this  Warrant  after  giving  effect  to  the  partial  exercise  of  this  Warrant  (including  the  delivery  of  any  Warrant
Shares as payment of the Exercise Price for such partial exercise of this Warrant).

4. Certain Adjustments. For so long as this Warrant is outstanding:

4.1 Mergers or Consolidations. If at any time after the date hereof there shall be a capital reorganization (other than a combination or
subdivision of Common Stock otherwise provided for herein) resulting in a reclassification to or change in the terms of securities issuable upon exercise of
this Warrant (a “Reorganization”), or a merger or consolidation of the Company with another corporation, association, partnership, organization, business,
individual, government or political subdivision thereof or a governmental agency (a “Person” or the “Persons”) (other than a merger with another Person
in  which  the  Company  is  a  continuing  corporation  and  which  does  not  result  in  any  reclassification  or  change  in  the  terms  of  securities  issuable  upon
exercise of this Warrant or a merger effected exclusively for the purpose of changing the domicile of the Company) (a “Merger”), then, as a part of such
Reorganization or Merger, lawful provision and adjustment shall be made so that the Holder shall thereafter be entitled to receive, upon exercise of this
Warrant, the number of shares of stock or any other equity or debt securities or property receivable upon such Reorganization or Merger by a holder of the
number of shares of Common Stock which might have been purchased upon exercise of this Warrant immediately prior to such Reorganization or Merger.
In any such case, appropriate adjustment shall be made in the application of the provisions of this Warrant with respect to the rights and interests of the
Holder after the Reorganization or Merger to the end that the provisions of this Warrant (including adjustment of the Exercise Price then in effect and the
number of Warrant Shares) shall be applicable after that event, as near as reasonably may be, in relation to any shares of stock, securities, property or other
assets thereafter deliverable upon exercise of this Warrant. The provisions of this Section 4.1 shall similarly apply to successive Reorganizations and/or
Mergers.

4.2 Splits and Subdivisions; Dividends. In the event the Company should at any time or from time to time effectuate a split or subdivision
of the outstanding shares of Common Stock or pay a dividend in or make a distribution payable in additional shares of Common Stock or other securities,
or rights convertible into, or entitling the holder thereof to receive, directly or indirectly, additional shares of Common Stock (hereinafter referred to as
“Common  Stock  Equivalents”)  without  payment  of  any  consideration  by  such  holder  for  the  additional  shares  of  Common  Stock  or  Common  Stock
Equivalents (including the additional shares of Common Stock issuable upon conversion or exercise thereof), then, as of the applicable record date (or the
date of such distribution, split or subdivision if no record date is fixed), the per share Exercise Price shall be appropriately decreased and the number of
Warrant  Shares  shall  be  appropriately  increased  in  proportion  to  such  increase  (or  potential  increase)  of  outstanding  shares;  provided,  however,  that  no
adjustment shall be made in the event the split, subdivision, dividend or distribution is not effectuated.

4

 
 
 
 
 
 
 
 
 
 
4.3 Combination of Shares. If the number of shares of Common Stock outstanding at any time after the date hereof is decreased by a
combination of the outstanding shares of Common Stock, the per share Exercise Price shall be appropriately increased and the number of shares of Warrant
Shares shall be appropriately decreased in proportion to such decrease in outstanding shares.

4.4 Adjustments for Other Distributions.  In  the  event  the  Company  shall  declare  a  distribution  payable  in  securities  of  other  Persons,
evidences of indebtedness issued by the Company or other Persons, assets (excluding cash dividends or distributions to the holders of Common Stock paid
out of current or retained earnings and declared by the Company’s Board of Directors) or options or rights not referred to in Sections 4.2 or 4.3 then, in
each  such  case  for  the  purpose  of  this  Section  4.4,  upon  exercise  of  this  Warrant,  the  Holder  shall  be  entitled  to  a  proportionate  share  of  any  such
distribution as though the Holder was the actual record holder of the number of Warrant Shares as of the record date fixed for the determination of the
holders of Common Stock of the Company entitled to receive such distribution.

5. No Impairment.  The  Company  will  not,  by  amendment  of  its  certificate  of  incorporation  or  by-laws  or  through  any  consolidation,  merger,
reorganization, transfer of assets, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all of the terms and in the taking of all actions necessary or
appropriate in order to protect the rights of the Holder against impairment.

6. Notice as to Adjustments. With respect to each adjustment pursuant to Section 4 of this Warrant, the Company, at its expense, will promptly
compute the adjustment or re-adjustment in accordance with the terms of this Warrant and furnish the Holder with a certificate certified and confirmed by
the  Secretary  or  Chief  Financial  Officer  of  the  Company  setting  forth,  in  reasonable  detail,  the  event  requiring  the  adjustment  or  re-adjustment  and  the
amount of such adjustment or re-adjustment, the method of calculation thereof and the facts upon which the adjustment or re-adjustment is based, and the
Exercise Price and the number of Warrant Shares or other securities purchasable hereunder after giving effect to such adjustment or re-adjustment, which
report shall be mailed by first class mail, postage prepaid to the Holder.

7. Reservation of Shares. The Company shall, solely for the purpose of effecting the exercise of this Warrant, at all times during the term of this
Warrant, reserve and keep available out of its authorized shares of Common Stock, free from all taxes, liens and charges with respect to the issue thereof
and not subject to preemptive rights of shareholders of the Company, such number of its shares of Common Stock as shall from time to time be sufficient to
effect in full the exercise of this Warrant. If at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect in
full the exercise of this Warrant, in addition to such other remedies as shall be available to Holder, the Company will promptly take such corporate action as
may, in the opinion of its counsel, be necessary to increase the number of authorized but unissued shares of Common Stock to such number of shares as
shall be sufficient for such purposes, including without limitation, using its Reasonable Commercial Efforts (as defined in Section 14 hereof) to obtain the
requisite shareholder approval necessary to increase the number of authorized shares of Common Stock. The Company hereby represents and warrants that
all shares of Common Stock issuable upon proper exercise of this Warrant shall be duly authorized and, when issued and paid for upon proper exercise,
shall be validly issued, fully paid and nonassessable.

8. Registration and Listing.

8.1 Definition  of  Registrable  Securities;  Majority.  As  used  herein,  the  term  “Registrable  Securities”  means  any  shares  of  Common
Stock issuable upon the exercise of this Warrant until the date (if any) on which such shares shall have been transferred or exchanged and new certificates
for  them  not  bearing  a  legend  restricting  further  transfer  shall  have  been  delivered  by  the  Company  and  subsequent  disposition  of  the  shares  shall  not
require  registration  or  qualification  under  the  Securities  Act  or  any  similar  state  law  then  in  force.  For  purposes  of  this  Warrant,  the  term  “Majority
Holders” shall mean in excess of fifty percent (50%) of the then outstanding Warrant Shares.

8.2 Demand Registration Rights.

(a) The Company, upon written demand (“Demand Notice”) of the Majority Holders, agrees to register on one occasion all of
the Registrable Securities (a “Demand Right”).  On  such  occasion,  the  Company  will  file  a  registration  statement  or  a  post-effective  amendment  to  the
Registration Statement covering the Registrable Securities within forty-five (45) days after receipt of a Demand Notice and use its Reasonable Commercial
Efforts  to  have  such  registration  statement  or  post-effective  amendment  declared  effective  as  soon  as  possible  thereafter;  provided,  however,  that  the
Company  shall  not  be  required  to  comply  with  a  Demand  Notice  if  the  Company  has  filed  a  registration  statement  with  respect  to  which  the  Holder  is
entitled to piggyback registration rights pursuant to Section 8.3 hereof and either: (i) the Holder has elected to participate in the offering covered by such
registration  statement  or  (ii)  if  such  registration  statement  relates  to  an  underwritten  primary  offering  of  securities  of  the  Company,  until  the  offering
covered by such registration statement has been withdrawn or until thirty (30) days after such offering is consummated. The demand for registration may be
made at any time during a period of four years beginning one (1) year from the Base Date. The Company covenants and agrees to give written notice of its
receipt of any Demand Notice to all other registered Holders of the Warrants and/or the Registrable Securities within ten days from the date of the receipt
of any such Demand Notice.

(b) The Company shall bear all fees and expenses attendant to registering the Registrable Securities pursuant to Section 8.2(a),
but  the  Holders  shall  pay  any  and  all  underwriting  commissions  and  the  expenses  of  any  legal  counsel  selected  by  the  Holders  to  represent  them  in
connection with the sale of the Registrable Securities. The Company agrees to use its Reasonable Commercial Efforts to qualify or register the Registrable
Securities  in  such  states  as  are  reasonably  requested  by  the  Majority  Holder(s);  provided,  however,  that  in  no  event  shall  the  Company  be  required  to
register the Registrable Securities in a state in which such registration would cause (i) the Company to be obligated to register, license or qualify to do
business in such state, submit to general service of process in such state or would subject the Company to taxation as a foreign corporation doing business
in such jurisdiction or (ii) the principal stockholders of the Company to be obligated to escrow their shares of capital stock of the Company. The Company
shall cause any registration statement or post-effective amendment filed pursuant to the Demand Right granted under Section 8.2(a) to remain effective for
a period of nine consecutive months from the effective date of such registration statement or post-effective amendment. The Holders shall only use the
prospectuses provided by the Company to sell the Registrable Securities covered by such registration statement, and will immediately cease to use any
prospectus furnished by the Company if the Company advises the Holder that such prospectus may no longer be used due to a material misstatement or
omission.

8.3 Incidental Registration Rights.

(a) If the Company, for a period of six (6) years commencing one (1) year after the Base Date, proposes to register any of its
securities  under  the  Securities  Act  (other  than  in  connection  with  a  transaction  contemplated  by  Rule  145(a)  promulgated  under  the  Securities Act  or
pursuant to registration on Form S-4 or S-8 or any successor forms) whether for its own account or for the account of any holder or holders of its shares
other than Registrable Securities (any shares of such holder or holders (but not those of the Company and not Registrable Securities) with respect to any
registration are referred to herein as, “Other Shares”), the Company shall at each such time give prompt (but not less than thirty (30) days prior to the
anticipated effectiveness thereof) written notice to the holders of Registrable Securities of its intention to do so. The holders of Registrable Securities shall
exercise  the  “piggy-back”  rights  provided  herein  by  giving  written  notice  within  ten  (10)  days  after  the  receipt  of  any  such  notice  (which  request  shall
specify the Registrable Securities intended to be disposed of by such holder). Except as set forth in Section 8.3(b), the Company will use its Reasonable
Commercial  Efforts  to  effect  the  registration  under  the  Securities Act  of  all  of  the  Registrable  Securities  which  the  Company  has  been  so  requested  to
register by such holder, to the extent required to permit the disposition of the Registrable Securities so to be registered, by inclusion of such Registrable
Securities  in  the  registration  statement  which  covers  the  securities  which  the  Company  proposes  to  register.  The  Company  will  pay  all  Registration
Expenses in connection with each registration of Registrable Securities pursuant to this Section 8.3.

(b) If the Company at any time proposes to register any of its securities under the Securities Act as contemplated by this Section
8.3 and such securities are to be distributed by or through one or more underwriters, the Company will, if requested by a holder of Registrable Securities,
use  its  Reasonable  Commercial  Efforts  to  arrange  for  such  underwriters  to  include  all  the  Registrable  Securities  to  be  offered  and  sold  by  such  holder
among  the  securities  to  be  distributed  by  such  underwriters,  provided  that  if  the  managing  underwriter  of  such  underwritten  offering  shall  inform  the
Company by letter of its belief that inclusion in such registration statement and/or distribution of all or a specified number of such securities proposed to be
distributed by such underwriters would interfere with the successful marketing of the securities being distributed by such underwriters (such letter to state
the basis of such belief and the approximate number of such Registrable Securities, such Other Shares and shares held by the Company proposed so to be
registered  which  may  be  distributed  without  such  effect),  then  the  Company  may,  upon  written  notice  to  such  holder,  the  other  holders  of  Registrable
Securities, and holders of such Other Shares, reduce pro rata in accordance with the number of shares of Common Stock desired to be included in such
registration statement and/or distribution (if and to the extent stated by such managing underwriter to be necessary to eliminate such effect) the number of
such  Registrable  Securities  and  Other  Shares  the  registration  and/or  distribution  of  which  shall  have  been  requested  by  each  holder  thereof  so  that  the
resulting aggregate number of such Registrable Securities and Other Shares so included in such registration and/or distribution, together with the number of
securities  to  be  included  in  such  registration  and/or  distribution  for  the  account  of  the  Company,  shall  be  equal  to  the  number  of  shares  stated  in  such
managing underwriter’s letter.

8.4 Registration Procedures. Whenever the holders of Registrable Securities have properly requested that any Registrable Securities be
registered pursuant to the terms of this Warrant, the Company shall use its Reasonable Commercial Efforts to effect the registration for the sale of such
Registrable Securities in accordance with the intended method of disposition thereof, and pursuant thereto the Company shall as expeditiously as possible:

Commercial Efforts to cause such registration statement to become effective;

(a)  prepare  and  file  with  the  SEC  a  registration  statement  with  respect  to  such  Registrable  Securities  and  use  its  Reasonable

(b) notify such holders of the effectiveness of each registration statement filed hereunder and prepare and file with the SEC such
amendments  and  supplements  to  such  registration  statement  and  the  prospectus  used  in  connection  therewith  as  may  be  necessary  to  (i)  keep  such
registration statement effective and the prospectus included therein usable for a period commencing on the date that such registration statement is initially
declared effective by the SEC and ending on the earlier of (A) the date when all Registrable Securities covered by such registration statement have been
sold pursuant to the registration statement or cease to be Registrable Securities, or (B) nine months from the effective date of the registration statement; and
(ii)  comply  with  the  provisions  of  the  Securities  Act  with  respect  to  the  disposition  of  all  securities  covered  by  such  registration  statement  during  such
period in accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement;

(c) furnish to such holders such number of copies of such registration statement, each amendment and supplement thereto, the
prospectus included in such registration statement (including each preliminary prospectus) and such other documents as such seller may reasonably request
in order to facilitate the disposition of the Registrable Securities owned by such holders;

(d) use its Reasonable Commercial Efforts to register or qualify such Registrable Securities under such other securities or blue
sky laws of such jurisdictions as such holders reasonably request and do any and all other acts and things which may be reasonably necessary or advisable
to enable such holders to consummate the disposition in such jurisdictions of the Registrable Securities owned by such holders; provided, however, that the
Company shall not be required to: (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this
subparagraph; (ii) subject itself to taxation in any such jurisdiction; or (iii) consent to general service of process in any such jurisdiction;

(e) notify such holders, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the
happening of any event as a result of which the prospectus included in such registration statement contains an untrue statement of a material fact or omits
any material fact necessary to make the statements therein, in light of the circumstances in which they are made, not materially misleading, and, at the
reasonable  request  of  such  holders,  the  Company  shall  prepare  a  supplement  or  amendment  to  such  prospectus  so  that,  as  thereafter  delivered  to  the
purchasers  of  such  Registrable  Securities,  such  prospectus  shall  not  contain  an  untrue  statement  of  a  material  fact  or  omit  to  state  any  material  fact
necessary to make the statements therein, in light of the circumstances in which they are made, not materially misleading;

statement;

(f) provide a transfer agent and registrar for all such Registrable Securities not later than the effective date of such registration

(g) make available for inspection by any underwriter participating in any disposition pursuant to such registration statement, and
any attorney, accountant or other agent retained by any such underwriter, all financial and other records, pertinent corporate documents and properties of
the  Company,  and  cause  the  Company’s  officers,  directors,  managers,  employees  and  independent  accountants  to  supply  all  information  reasonably
requested by any such underwriter, attorney, accountant or agent in connection with such registration statement;

(h) otherwise use its Reasonable Commercial Efforts to comply with all applicable rules and regulations of the SEC, and make
available  to  its  security  holders,  as  soon  as  reasonably  practicable,  an  earnings  statement  of  the  Company,  which  earnings  statement  shall  satisfy  the
provisions of Section 11(a) of the Securities Act and, at the option of the Company, Rule 158 thereunder;

(i)  in  the  event  of  the  issuance  of  any  stop  order  suspending  the  effectiveness  of  a  registration  statement,  or  of  any  order
suspending  or  preventing  the  use  of  any  related  prospectus  or  suspending  the  qualification  of  any  Registrable  Securities  included  in  such  registration
statement for sale in any jurisdiction, the Company shall use its Reasonable Commercial Efforts promptly to obtain the withdrawal of such order; and

(j) if the offering is underwritten, use its Reasonable Commercial Efforts to furnish on the date that Registrable Securities are
delivered to the underwriters for sale pursuant to such registration, an opinion dated such date of counsel representing the Company for the purposes of
such registration, addressed to the underwriters covering such issues as are reasonably required by such underwriters.

8.5 Listing. The Company shall secure the listing of the Common Stock underlying this Warrant upon each national securities exchange
or automated quotation system upon which shares of Common Stock are then listed or quoted (subject to official notice of issuance) and shall maintain
such listing of shares of Common Stock. The Company shall at all times comply in all material respects with the Company’s reporting, filing and other
obligations under the by-laws or rules of The NASDAQ Stock Market (or such other national securities exchange or market on which the Common Stock
may then be listed, as applicable).

9

 
 
 
 
 
 
 
 
 
 
8.6 Expenses. The Company shall pay all Registration Expenses relating to the registration and listing obligations set forth in this Section
8. For purposes of this Warrant, the term “Registration Expenses” means: (a) all registration, filing and FINRA fees, (b) all reasonable fees and expenses
of complying with securities or blue sky laws, (c) all word processing, duplicating and printing expenses, (d) the fees and disbursements of counsel for the
Company and of its independent public accountants, including the expenses of any special audits or “cold comfort” letters required by or incident to such
performance  and  compliance,  (e)  premiums  and  other  costs  of  policies  of  insurance  (if  any)  against  liabilities  arising  out  of  the  public  offering  of  the
Registrable Securities being registered if the Company desires such insurance, if any, and (f) fees and disbursements of one counsel for the selling holders
of Registrable Securities; provided however, that, in any case where Registration Expenses are not to be borne by the Company, such expenses shall not
include (and such expenses shall be borne by the Company): (i) salaries of Company personnel or general overhead expenses of the Company, (ii) auditing
fees, or (iii) other expenses for the preparation of financial statements or other data, to the extent that any of the foregoing either is normally prepared by
the Company in the ordinary course of its business or would have been incurred by the Company had no public offering taken place. Registration Expenses
shall not include any underwriting discounts and commissions which may be incurred in the sale of any Registrable Securities and transfer taxes of the
selling holders of Registrable Securities.

8.7 Information Provided by Holders. Any holder of Registrable Securities included in any registration shall furnish to the Company such
information  as  the  Company  may  reasonably  request  in  writing,  including,  but  not  limited  to,  a  completed  and  executed  questionnaire  requesting
information customarily sought of selling security holders, to enable the Company to comply with the provisions hereof in connection with any registration
referred to in this Warrant. The Holder agrees to suspend all sales of Registrable Securities pursuant to a registration statement filed under Section 8.3 in
the event the Company notifies Holder pursuant to Section 8.4(e) that the prospectus relating thereto is no longer current and will not resume sales under
such registration statement until advised by the Company that the prospectus has been appropriately supplemented or amended.

8.8 FINRA Public Offering System Filings. In the event that a registration statement covering the Registrable Securities is filed, within
one (1) Business Day of the filing of such registration statement, the Company will prepare and file the selling stockholder resale offering described in such
registration statement for review by FINRA via the FINRA’s Public Offering System filing system (“Public Offering System Filing”) for the purpose of
having the prospectus contained within such registration statement treated as a “base prospectus” in connection with such resale offering. The Company
will use its Reasonable Commercial Efforts to have the Public Offering System Filing approved by FINRA within thirty (30) days of such filing date. The
Company shall bear all expenses of the Public Offering System Filing, including fees and expenses of one counsel or other advisor to the Holder. In all
circumstances, the Company shall pay for all FINRA filing fees associated with the Public Offering System Filing.

8.9 Effectiveness Period. The Company shall use its Reasonable Commercial Efforts to keep each registration statement contemplated
hereunder  continuously  effective  under  the  Securities  Act  until  the  date  which  is  the  earlier  date  of  when  (i)  all  Registrable  Securities  covered  by  such
Registration Statement have been sold, (ii) all Registrable Securities covered by such Registration Statement may be sold immediately without registration
under  the  Securities  Act  and  without  volume  restrictions  pursuant  to  Rule  144  under  the  Securities  Act,  as  determined  by  the  counsel  to  the  Company
pursuant  to  a  written  opinion  letter  to  such  effect,  addressed  and  reasonably  acceptable  to  the  Company’s  transfer  agent  and  the  affected  holders  of
Registrable Securities, or (iii) nine months from the effective date of such registration statement.

10

 
 
 
 
 
 
 
 
8.10 Net Cash Settlement. Notwithstanding anything herein to the contrary, in no event will the Holder hereof be entitled to receive a net-
cash settlement as liquidated damages in lieu of physical settlement in shares of Common Stock, regardless of whether the Common Stock underlying this
Warrant is registered pursuant to an effective registration statement; provided, however, that the foregoing will not preclude the Holder from seeking other
remedies at law or equity for breaches by the Company of its registration obligations hereunder.

9. Restrictions on Transfer.

9.1 Restrictive Legends. This Warrant and each Warrant issued upon transfer or in substitution for this Warrant pursuant to Section 10
hereof, each certificate for Common Stock issued upon the exercise of the Warrant and each certificate issued upon the transfer of any such Common Stock
shall  be  transferable  only  upon  satisfaction  of  the  conditions  specified  in  this  Section  9.  Each  of  the  foregoing  securities  shall  be  stamped  or  otherwise
imprinted  with  a  legend  reflecting  the  restrictions  on  transfer  set  forth  herein  and  any  restrictions  required  under  the  Securities  Act  or  other  applicable
securities laws.

9.2 Notice of Proposed Transfer. Prior to any transfer of any securities which are not registered under an effective registration statement
under the Securities Act (“Restricted Securities”), which transfer may only occur if there is an exemption from the registration provisions of the Securities
Act and all other applicable securities laws, the Holder will give written notice to the Company of the Holder’s intention to effect a transfer (and shall
describe the manner and circumstances of the proposed transfer). The following provisions shall apply to any proposed transfer of Restricted Securities:

(i)  If  in  the  opinion  of  counsel  for  the  Holder  reasonably  satisfactory  to  the  Company  the  proposed  transfer  may  be  effected
without  registration  of  the  Restricted  Securities  under  the  Securities  Act  (which  opinion  shall  state  in  detail  the  basis  of  the  legal  conclusions  reached
therein), the Holder shall thereupon be entitled to transfer the Restricted Securities in accordance with the terms of the notice delivered by the Holder to the
Company. Each certificate representing the Restricted Securities issued upon or in connection with any transfer shall bear the restrictive legends required
by Section 9.1 hereof.

(ii) If the opinion called for in (i) above is not delivered, the Holder shall not be entitled to transfer the Restricted Securities until
either:  (x)  receipt  by  the  Company  of  a  further  notice  from  such  Holder  pursuant  to  the  foregoing  provisions  of  this  Section  9.2  and  fulfillment  of  the
provisions of clause (i) above, or (y) such Restricted Securities have been effectively registered under the Securities Act.

9.3 Certain Other Transfer Restrictions. Notwithstanding any other provision of this Warrant: (i) prior to the Exercise Date, this Warrant
or the Restricted Securities thereunder may only be transferred or assigned to the persons permitted under FINRA Rule 5110(g), and (ii) subject at all times
to FINRA Rule 5110(g), no opinion of counsel shall be necessary for a transfer of Restricted Securities by the holder thereof to any Person employed by or
owning equity in the Holder, if the transferee agrees in writing to be subject to the terms hereof to the same extent as if the transferee were the original
purchaser hereof and such transfer is permitted under applicable securities laws.

11

 
 
 
 
 
 
 
 
 
 
 
9.4 Termination of Restrictions. Except as set forth in Section 9.3 hereof and subject at all times to FINRA Rule 5110(g), the restrictions
imposed by this Section 9 upon the transferability of Restricted Securities shall cease and terminate as to any particular Restricted Securities: (a) which
shall  have  been  effectively  registered  under  the  Securities  Act,  or  (b)  when,  in  the  opinion  of  counsel  for  the  Company,  such  restrictions  are  no  longer
required  in  order  to  insure  compliance  with  the  Securities  Act  or  Section  10  hereof.  Whenever  such  restrictions  shall  cease  and  terminate  as  to  any
Restricted Securities, the Holder thereof shall be entitled to receive from the Company, without expense (other than applicable transfer taxes, if any), new
securities of like tenor not bearing the applicable legends required by Section 9.1 hereof.

10. Ownership, Transfer, Sale and Substitution of Warrant.

10.1  Ownership  of  Warrant.  The  Company  may  treat  any  Person  in  whose  name  this  Warrant  is  registered  in  the  Warrant  Register
maintained pursuant to Section 10.2(b) hereof as the owner and holder thereof for all purposes, notwithstanding any notice to the contrary, except that, if
and when any Warrant is properly assigned in blank, the Company may (but shall not be obligated to) treat the bearer thereof as the owner of such Warrant
for all purposes, notwithstanding any notice to the contrary. Subject to Sections 9 and 10 hereof, this Warrant, if properly assigned, may be exercised by a
new holder without a new Warrant first having been issued.

10.2 Office; Exchange of Warrant.

(a) The Company will maintain its principal office at the location identified in the prospectus relating to the Offering or at such
other offices as set forth in the Company’s most current filing (as of the date notice is to be given) under the Securities Exchange Act of 1934, as amended,
or as the Company otherwise notifies the Holder.

(b) The Company shall cause to be kept at its office maintained pursuant to Section 10.2(a) hereof a Warrant Register for the
registration and transfer of the Warrant. The name and address of the holder of the Warrant, the transfers thereof and the name and address of the transferee
of the Warrant shall be registered in such Warrant Register. The Person in whose name the Warrant shall be so registered shall be deemed and treated as the
owner and holder thereof for all purposes of this Warrant, and the Company shall not be affected by any notice or knowledge to the contrary.

(c)  Upon  the  surrender  of  this  Warrant,  properly  endorsed,  for  registration  of  transfer  or  for  exchange  at  the  office  of  the
Company  maintained  pursuant  to  Section  10.2(a)  hereof,  the  Company  at  its  expense  will  (subject  to  compliance  with  Section  9  hereof,  if  applicable)
execute and deliver to or upon the order of the Holder thereof a new Warrant of like tenor, in the name of such holder or as such holder (upon payment by
such holder of any applicable transfer taxes) may direct, calling in the aggregate on the face thereof for the number of shares of Common Stock called for
on the face of the Warrant so surrendered (after giving effect to any previous adjustment(s) to the number of Warrant Shares).

12

 
 
 
 
 
 
 
 
 
 
 
10.3  Replacement  of  Warrant.  Upon  receipt  of  evidence  reasonably  satisfactory  to  the  Company  of  the  loss,  theft,  destruction  or
mutilation of this Warrant and, in the case of any such loss, theft or destruction of this Warrant, upon delivery of indemnity reasonably satisfactory to the
Company in form and amount or, in the case of any mutilation, upon surrender of this Warrant for cancellation at the office of the Company maintained
pursuant to Section 10.2(a) hereof, the Company will execute and deliver, in lieu thereof, a new Warrant of like tenor and dated the date hereof.

10.4 Opinions. In connection with the sale of the Warrant Shares by Holder, the Company agrees to cooperate with the Holder, and at the
Company’s expense, to have its counsel provide any legal opinions required to remove the restrictive legends from the Warrant Shares in connection with a
sale, transfer or legend removal request of Holder.

11. Indemnification. In connection with any Registration Statement or any other disclosure document pursuant to which securities of the Company
are sold, the Company will, and hereby does, jointly and severally, indemnify and hold harmless the Holder, its directors, officers, fiduciaries, and agents
(each, a “Covered Person”) against any losses, claims, damages or liabilities, joint or several, to which such Covered Person may be or become subject
under  the  Securities  Act,  any  other  securities  or  other  laws  of  any  jurisdiction,  common  law  or  otherwise,  insofar  as  such  losses,  claims,  damages  or
liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (1) any untrue statement or alleged untrue statement of any material
fact contained or incorporated by reference in any Registration Statement under the Securities Act, any preliminary prospectus or final prospectus included
therein, or any amendment or supplement thereto, or any document incorporated by reference therein, or any other such disclosure document, or (2) any
omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statement therein not misleading, and will
reimburse such Covered Person for any legal or any other expenses incurred in connection with investigating or defending any such loss, claim, damage,
liability, action or proceeding, provided, however, the Company shall not be liable to any Covered Person in any such case to the extent that any such loss,
claim, damage, liability, action or proceeding is determined, by a final, non-appealable judgment by a court or arbitral tribunal of competent jurisdiction, to
have arisen out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement,
any such preliminary prospectus, final prospectus, amendment or supplement, any document incorporated by reference or other such disclosure document
in  reliance  upon  and  in  conformity  with  written  information  furnished  to  the  Company  through  an  instrument  duly  executed  by  such  Covered  Person
specifically stating that it is for use in the preparation thereof.

12. No Rights or Liabilities as Stockholder. No Holder shall be entitled to vote or be deemed the holder of any equity securities which may at any
time  be  issuable  on  the  exercise  hereof,  nor  shall  anything  contained  herein  be  construed  to  confer  upon  the  Holder,  as  such,  any  of  the  rights  of  a
stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give
or  withhold  consent  to  any  corporate  action  (whether  upon  any  recapitalization,  issuance  of  stock,  reclassification  of  stock,  change  of  par  value,
consolidation, merger, conveyance, or otherwise) or to receive notice of meetings until the Warrant shall have been exercised and the shares of Common
Stock purchasable upon the exercise hereof shall have become deliverable, as provided herein.

13

 
 
 
 
 
 
 
 
13. Notices. Any  notice  or  other  communication  in  connection  with  this  Warrant  shall  be  given  in  writing  and  directed  to  the  parties  hereto  as
follows: (a) if to the Holder, at the address of the holder in the warrant register maintained pursuant to Section 10 hereof, or (b) if to the Company, to the
attention of its Chief Executive Officer at its office maintained pursuant to Section 10.2(a) hereof; provided, that the exercise of the Warrant shall also be
effected  in  the  manner  provided  in  Section  3  hereof.  Notices  shall  be  deemed  properly  delivered  and  received  when  delivered  to  the  notice  party  (i)  if
personally delivered, upon receipt or refusal to accept delivery, (ii) if sent via facsimile, upon mechanical confirmation of successful transmission thereof
generated by the sending telecopy machine, (iii) if sent by a commercial overnight courier for delivery on the next Business Day, on the first Business Day
after deposit with such courier service, (iv) if sent by registered or certified mail, five (5) Business Days after deposit thereof in the U.S. mail, or (v) if sent
by email, the date of transmission if such notice or communication is delivered via email at the email address specified in the Underwriting Agreement
prior to 5:00 p.m. (prevailing Pacific time) on a Business Day, or the next Business Day after the date of transmission if such notice or communication is
delivered via email at the email address specified in the Underwriting Agreement on a day that is not a Business Day or later than 5:00 p.m. (prevailing
Pacific time) on a Business Day.

14. Payment of Taxes. The Company will pay all documentary stamp taxes attributable to the issuance of shares of Common Stock underlying this
Warrant upon exercise of this Warrant; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any
transfer involved in the transfer or registration of this Warrant or any certificate for shares of Common Stock underlying this Warrant in a name other that
of the Holder. The Holder is responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving shares of
Common Stock underlying this Warrant upon exercise hereof.

15. Miscellaneous. This Warrant and any term hereof may be changed, waived, discharged or terminated only by an instrument in writing signed
by  the  party  against  which  enforcement  of  the  change,  waiver,  discharge  or  termination  is  sought.  This  Warrant  shall  be  construed  and  enforced  in
accordance with and governed by the laws of the State of New York. Each of the parties consents to the exclusive jurisdiction of the Federal or state courts
whose districts encompass any part of the County of New York located in the City of New York, New York in connection with any dispute arising under
this Agreement and hereby waives, to the maximum extent permitted by law, any objection, including any objection based on forum non conveniens, to the
bringing of any such proceeding in such jurisdictions. Each party to this Agreement irrevocably consents to the service of process in any such proceeding
by any manner permitted by law. The section headings in this Warrant are for purposes of convenience only and shall not constitute a part hereof. In case
any one or more of the provisions of this Warrant shall be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms
and provisions of this Warrant shall not in any way be affected or impaired thereby, and the parties will attempt in good faith to agree upon a valid and
enforceable provision which shall be a commercially reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this
Warrant. When used herein, the term “Reasonable Commercial Efforts” means,  with  respect  to  the  applicable  obligation  of  the  Company,  reasonable
commercial efforts for similarly situated, publicly-traded companies.
