Overview

PART I

We  are  a  late-stage  clinical  biopharmaceutical  company  focused  on  the  development  and  commercialization  of  novel  products  utilizing  our  proprietary
PRINT® technology to transform the lives of patients. PRINT is a particle engineering platform that enables precise production of uniform drug particles
designed  to  improve  the  safety,  efficacy  and  performance  of  a  wide  range  of  therapies.  We  are  currently  focused  on  the  development  of  two  product
candidates  for  which  we  hold  worldwide  commercial  rights:  LIQ861  for  the  treatment  of  pulmonary  arterial  hypertension,  or  PAH,  and  LIQ865  for  the
treatment  of  local  post-operative  pain.  LIQ861,  for  which  we  recently  filed  a  New  Drug  Application,  or  NDA,  with  the  FDA,  is  an  inhaled  dry  powder
formulation of treprostinil designed to improve the therapeutic profile of treprostinil by enhancing deep-lung delivery and achieving higher dose levels than
current inhaled therapies. We have applied our PRINT technology to enable us to deliver LIQ861 through a convenient, palm-sized dry powder inhaler, or
DPI. We have also applied our PRINT technology to our second product candidate, LIQ865, for which we have completed two Phase 1 clinical trials and
have initiated Phase 2-enabling toxicology studies. LIQ865 is designed to deliver sustained-release particles of bupivacaine, a non-opioid anesthetic, to treat
local  post-operative  pain  for  three  to  five  days  through  a  single  administration.  Additionally,  we  recently  initiated  a  pre-clinical  program  to  develop  an
inhaled product leveraging the benefits of our PRINT technology to engineer particles with precise, uniform, aerodynamic size and shape for deep lung
delivery. 

LIQ861 for Pulmonary Arterial Hypertension

In January 2020, we submitted an NDA to the FDA for LIQ861, our lead product candidate, as a potential treatment for patients with PAH. Treprostinil is a
synthetic analog of prostacyclin, a vasoactive mediator essential to normal lung function, which is deficient in patients with PAH. We believe that LIQ861
has the potential to improve the therapeutic profile of existing formulations of treprostinil by enhancing deep-lung delivery and achieving higher dose levels
than  current  inhaled  therapies.  We  are  developing  LIQ861  under  the  505(b)(2)  regulatory  pathway  with  Tyvaso®  (treprostinil,  inhaled  solution)  as  the
reference listed drug, which allows us to rely in part on the FDA’s previous findings of efficacy and safety of Tyvaso and the active ingredient treprostinil,
which has been approved in four different products administered through the oral, inhaled and continuous infusion (parenteral) routes.

PAH is a chronic, progressive disease caused by the hardening and narrowing of the pulmonary arteries that can lead to right heart failure and eventually
death. Treprostinil is a synthetic analog of prostacyclin, a vasoactive mediator essential to normal lung function that is deficient in patients with PAH. PAH
is a rare disease, with an estimated prevalence in the United States of approximately 30,000 patients. An independent industry research firm estimated that
in 2019 products containing treprostinil across its three routes of administration (oral, inhaled and parenteral infusion) may generate revenue that represents
about one-quarter of the approximately $3.5 billion U.S. market for pulmonary hypertension drug therapies. The inhaled route of administration, in which
medication  is  inhaled  directly  into  the  lungs,  helps  minimize  the  off-tissue  adverse  side  effects  of  systemic  delivery.  Tyvaso,  marketed  by
United  Therapeutics  in  the  United  States,  is  the  standard  of  care  among  the  inhaled  therapies,  with  more  than  80%  of  inhaled  prostacyclin  sales  in  the
United States. Current inhaled therapies, including Tyvaso, are delivered by a nebulizer, a device that converts a liquid formulation into mist, and require
between four and nine doses per day. Nebulizers require regular care and maintenance, including daily cleaning and access to additional parts and supplies,
such as distilled water and a power source, all of which compromise the portability of the device and the quality of life of patients.

We believe LIQ861, if approved, will be the first-to-market inhaled dry powder treprostinil that can be delivered using a convenient, palm-sized DPI. We
further  believe  that  LIQ861  can  overcome  the  limitations  of  current  inhaled  therapies  and  has  the  potential  to  maximize  the  therapeutic  benefits  of
treprostinil in treating PAH by safely delivering higher doses into the lungs. Based on our in vitro studies we believe that the precise size, trefoil-like shape
and uniformity of each LIQ861 particle may provide deep-lung delivery of treprostinil and may reduce deposition in the upper airway where irritation and
pain have been observed with nebulized treprostinil.

In August 2019, we completed an open-label Phase 3 clinical trial, INSPIRE, or Investigation of the Safety and Pharmacology of Dry Powder Inhalation of
Treprostinil,  for  LIQ861.  The  primary  objective  of  the  INSPIRE  study  was  to  evaluate  the  long-term  safety  and  tolerability  of  LIQ861.  The  study  was
designed to evaluate patients who have either been under stable treatment with Tyvaso (nebulizer-delivered treprostinil), for at least three months and were
transitioned to LIQ861 under the protocol, or Transition patients, or patients who had been under stable treatment with no more than two non-prostacyclin
oral  PAH  therapies  for  at  least  three  months  and  then  had  their  treatment  regimen  supplemented  with  LIQ861  under  the  protocol,  or  Add-On  patients.
Within the INSPIRE study, 18 Transition patients were evaluated in a one-directional crossover sub-study comparing bioavailability and pharmacokinetics,
or PK, of treprostinil following dosing of LIQ861 as compared with Tyvaso.

In March 2019, we reported that we had completed enrollment and met the primary endpoint, which was long-term safety and tolerability, in our INSPIRE
trial. LIQ861 was observed to be well-tolerated in 109 patients, with 101 patients (93%) completing at least two months of treatment. During the two-month
period, LIQ861 was evaluated at doses up to 159 mcg (clinical trial nomenclature of 150 mcg capsule strength) with no study-drug related serious adverse
events. Dosing has exceeded 159 mcg in some patients receiving drug beyond the Month 2 time point. We have not yet determined a maximum tolerated
dose  of  LIQ861.  We  also  reported  fully  enrolling  our  one-directional  crossover  sub-study  comparing  bioavailability  and  PK  of  treprostinil  as  sub-study
patients transitioned from Tyvaso to LIQ861.

In April 2019, we reported further data from these 109 patients in our INSPIRE trial on exploratory endpoints at two months of treatment that demonstrated
generally  favorable  results  with  respect  to  six-minute  walk  distance  and  quality  of  life  as  indicated  by  the  Minnesota  Living  with  Heart  Failure
Questionnaire, or MLHFQ. In May 2019, we reported further presentation of this data at the American Thoracic Society, or ATS, International Conference
2019.

In  June  2019,  we  reported  results  from  the  INSPIRE  study  indicating  that  the  79.5  mcg  dose  of  LIQ861  (clinical  trial  nomenclature  of  75  mcg  capsule
strength) correlates with nine breaths of Tyvaso, the maximum recommended label dose of Tyvaso. Analysis of the data from the PK sub-study in patients
showed variability in systemic plasma levels of both LIQ861 and Tyvaso, which is believed to be attributed to variation in severity of disease and has been
seen  in  prior  studies  of  treprostinil  in  patients.  To  more  accurately  characterize  the  PK  of  LIQ861,  we  conducted  two  additional  PK  studies  in  healthy
volunteers. In the first of these studies, we observed unexpected variability in PK levels. Post-hoc analysis showed that plasma levels of treprostinil were
tightly correlated to the LIQ861 dose delivered. Based upon additional non-clinical and clinical work, we believe the unexpected variability seen in this
healthy volunteer study was due to an administration technique unique to the conduct of the study in the Phase 1 setting. In August 2019, we completed a
second PK study in healthy volunteers in which the proper administration technique was followed. This study demonstrated significantly reduced variability,
and we believe we have established comparative bioavailability to the reference listed drug.

Final enrollment in the pivotal INSPIRE trial included 121 PAH patients to assess safety and tolerability through Month 2, the primary endpoint of the trial.
Of  the  121  patients  enrolled  in  the  study,  55  were  Transition  patients  and  66  were  Add-On  patients.  Add-On  patients  started  on  a  dose  of  26.5  mcg  of
LIQ861 (clinical trial nomenclature of 25 mcg capsule strength), with most (>80%) titrating to a 79.5 mcg dose or higher within the first two months of
treatment.  Consistent  with  preliminary  data  presented  in  the  second  quarter  of  2019,  LIQ861  was  observed  to  be  well-tolerated  and  treatment-emergent
adverse events were mostly mild to moderate in nature at Month 2 up to doses of 159 mcg of LIQ861, the highest dose studied at Month 2. Durability of
therapy  with  LIQ861  appeared  to  be  favorable,  with  96%  of  Transition  patients  and  91%  of  Add-On  patients  remaining  on  study  drug  at  the  Month  2
timepoint.

Initial  analysis  of  the  exploratory  endpoints  from  the  INSPIRE  study  indicates  that  LIQ861  may  provide  functional  and  quality-of-life  benefits  to  PAH
patients in New York Heart Association, or NYHA, functional classes II and III. More than 90% of all patients who completed two months of treatment
maintained or improved their NYHA functional class. Additionally, we observed improvement in six-minute-walk-distance and quality of life as measured
by the MLHFQ in both patient groups.

We continued to treat patients who chose to remain on LIQ861 beyond the Month 2 timepoint of the primary endpoint. More than 80% of INSPIRE patients
remained on study drug at Month 4 with no significant changes in safety or tolerability observed compared to Month 2. At the completion of the INSPIRE
study, the patient with the longest duration of treatment had been on LIQ861 therapy for 18 months. To provide for continuity of treatment, patients from
INSPIRE were provided the opportunity to continue receiving treatment in an extension study, which is currently ongoing. In addition, we are enrolling
patients in a clinical study at certain investigational sites in Europe to characterize the hemodynamic dose-response relationship to LIQ861. We are also
considering conducting other clinical trials to generate additional data on LIQ861, including a clinical trial in pediatric patients. We also continue to conduct
development work in support of potential approval and commercialization of LIQ861, including label and patient-use assessments.

LIQ865 for Post-Operative Pain

LIQ865  is  our  proprietary  injectable,  sustained-release  formulation  of  bupivacaine,  a  non-opioid  pain  medication.  We  have  engineered  the  size  and
composition of the LIQ865 PRINT particles to release bupivacaine over three to five days through a single administration for the management of local post-
operative  pain  after  a  surgical  procedure.  We  completed  a  Phase  1a  clinical  trial  of  LIQ865  in  Denmark  in  2017  and  a  Phase  1b  clinical  trial  in  the
United States in 2018. We initiated Phase 2-enabling toxicology studies in 2019 to assess LIQ865 in multiple non-clinical tissue models. Results from a
study to assess incision tensile strength after healing were acceptable and not statistically different from controls. A nonclinical study to examine soft tissue
healing was also completed, and the results were acceptable and comparable to vehicle-treated, saline-treated, and Marcaine-treated sites. We believe this
data supports progression to Phase 2 hernia repair studies. In a study to assess bone fracture healing, we observed dose-dependent delayed healing at the two
LIQ865 doses studied; however, there were no adverse effects noted on surrounding soft tissues. Additional studies have been initiated with lower doses of
LIQ865 to determine a no adverse effect level, or NOAEL, on bone healing. We will review the results from these toxicology studies, and if supportive, we
intend to initiate Phase 2 proof-of-concept clinical trials, subject to availability of capital and other factors, during 2021. We believe LIQ865, if successfully
developed and approved, has the potential to provide significantly longer local post-operative pain relief compared to currently marketed formulations of
bupivacaine.

We  estimate  that  there  were  over  40  million  surgeries  in  our  target  market,  which  consists  of  orthopedic  and  soft  tissue  surgeries,  performed  in  the
United  States  in  2016.  According  to  IMS  Health,  an  independent  market  research  firm,  the  global  market  for  local  anesthetics  was  approximately
$761.1  million  in  2017.  Despite  current  pain-management  protocols,  post-operative  pain  is  still  undermanaged,  with  studies  showing  that  approximately
50%  of  patients  self-report  inadequate  pain  relief.  Post-operative  pain  management  is  becoming  more  important  as  surgeries  increase  in  volume  and
complexity and hospitals seek treatments that support faster recovery and time to discharge. Concurrently, the risk of opioid abuse and diversion has led
physicians, payors and the U.S. federal government to prioritize pain management strategies that minimize reliance on opioids. Local anesthetics, such as
bupivacaine,  provide  a  well-established,  non-opioid  option  for  post-operative  pain  management,  but  their  duration  of  efficacy  has  been  limited  to
eight  hours  or  less.  The  FDA  has  approved  one  long-acting  local  anesthetic,  liposomal  bupivacaine,  but  pain  relief  typically  lasts  only  24  to  36  hours,
according to physicians, and its use in combination with other local anesthetics can result in an unsafe release of drug.

Our PRINT Technology

Both  LIQ861  and  LIQ865  are  based  upon  our  proprietary  PRINT  particle  engineering  technology,  which  allows  us  to  engineer  and  manufacture  highly
uniform drug particles with precise control over their size, three-dimensional geometric shape and chemical composition. By controlling these physical and
chemical parameters of particles, PRINT enables us to target and design desirable pharmacological benefits into product candidates, including prolonged
duration of drug release, increased drug loading, a more convenient method of administration, novel combination products, enhanced storage and stability
and  the  potential  to  reduce  adverse  side  effects.  We  have  scaled  PRINT  manufacturing  to  meet  the  demands  of  clinical  development  and,  we  believe,
commercial production. Our approach enables us to design and produce custom micro- and nano-particles containing existing or new small molecule drugs
or biologics. For example, we have engineered LIQ861 so that each particle has an ideal, uniform, aerodynamic size and shape for deep-lung delivery. Our
PRINT particle engineering technology also allows us to design the chemical composition of particles to control drug release ranging from minutes, days,
weeks or months as needed to meet a target profile, such as LIQ865’s three to five day release of bupivacaine.

Development, Regulatory and Commercial Strategy

Initially, our internal pipeline is focused on the development of improved and differentiated drug products containing FDA-approved active pharmaceutical
ingredients, or APIs, with established efficacy and safety profiles, which we believe are eligible for the 505(b)(2) regulatory pathway to seek marketing
approval in the United States. The 505(b)(2) regulatory pathway can be capital efficient and potentially enable a shorter time to approval. We are seeking
marketing approval in the United States for LIQ861 under the 505(b)(2) regulatory pathway, which would allow us to rely in part on existing knowledge of
the  safety  and  efficacy  of  the  reference  listed  drugs.  The  FDA  has  indicated  that  it  considers  LIQ861,  which  is  delivered  by  a  DPI,  to  be  a  drug-device
combination  product  and,  accordingly,  the  DPI  will  be  evaluated  as  part  of  our  NDA  filing.  We  also  intend  to  develop  LIQ865  under  the  505(b)(2)
regulatory  pathway.  Additionally,  we  recently  initiated  a  pre-clinical  program  to  develop  an  inhaled  product  leveraging  the  benefits  of  our  PRINT
technology to engineer particles with precise, uniform, aerodynamic size and shape for deep lung delivery.

In  addition  to  building  our  own  internal  pipeline,  we  may  collaborate  with  pharmaceutical  companies  to  assist  in  the  development  of  their  product
candidates by leveraging our PRINT technology, which we believe has application across a wide range of therapeutic areas, molecule types and routes of
administration. If our product candidates receive marketing approval, we plan to commercialize them in the United States either by ourselves or through
partnership or licensing arrangements with other pharmaceutical companies. Outside of the United States, we intend to pursue the regulatory approval and
commercialization of our product candidates in collaboration with pharmaceutical companies with regional expertise. We intend to manufacture our product
candidates  using  in-house  capabilities.  Where  appropriate,  we  will  rely  on  contract  manufacturing  organizations,  or  CMOs,  to  produce,  package  and
distribute our approved drug products on a commercial scale.

Product Pipeline

The following table summarizes our clinical-stage product candidates being developed using PRINT technology.

Our Strategy

Our goal is to develop and commercialize medicines with improved and differentiated product profiles based on our PRINT particle engineering technology.
To achieve this goal, we intend to execute the following key elements of our business strategy:

● Obtain  regulatory  approval  of  LIQ861,  our  proprietary  dry  powder  inhalation  formulation  of  treprostinil.  In  January  2020,  we  submitted  an
NDA  to  the  FDA  for  LIQ861,  our  lead  product  candidate,  as  a  potential  treatment  for  patients  with  PAH.  Treprostinil  is  a  synthetic  analog  of
prostacyclin,  a  vasoactive  mediator  essential  to  normal  lung  function,  which  is  deficient  in  patients  with  PAH.  We  believe  that  LIQ861  has  the
potential  to  improve  the  therapeutic  profile  of  existing  formulations  of  treprostinil  by  enhancing  deep-lung  delivery  and  achieving  higher  dose
levels than current inhaled therapies. LIQ861 is being developed under the 505(b)(2) regulatory pathway with Tyvaso as the reference listed drug,
which allows us to rely in part on the FDA’s previous findings of efficacy and safety of Tyvaso and the active ingredient treprostinil, which has
been approved in four different products administered through the continuous infusion (parenteral), inhaled and oral routes. Our NDA submission
was supported by the favorable results of our pivotal Phase 3 trial, INSPIRE, conducted in 121 patients and completed during the third quarter of
2019.

● Advance our local post-operative pain product candidate, LIQ865, through Phase 2-enabling toxicology studies into Phase 2 clinical trials. We
completed a Phase 1a clinical trial of LIQ865 in Denmark in 2017 and a Phase 1b clinical trial in the United States in 2018. We initiated Phase 2-
enabling toxicology studies in 2019 to assess LIQ865 in multiple non-clinical tissue models. Results from a study to assess incision tensile strength
after healing were acceptable and not statistically different from controls. A nonclinical study to examine soft tissue healing was also completed,
and  the  results  were  acceptable  and  comparable  to  vehicle-treated,  saline-treated,  and  Marcaine-treated  sites.  We  believe  this  data  supports
progression to Phase 2 hernia repair studies. In a study to assess bone fracture healing, we observed dose-dependent delayed healing at the two
LIQ865  doses  studied;  however,  there  were  no  adverse  effects  noted  on  surrounding  soft  tissues.  Additional  studies  have  been  initiated  with
lower doses of LIQ865 to determine a NOAEL on bone healing. We will review the results from these toxicology studies, and if supportive, we
intend to initiate Phase 2 proof-of-concept clinical trials, subject to availability of capital and other factors, during 2021. We believe LIQ865, if
successfully  developed  and  approved,  has  the  potential  to  provide  significantly  longer  local  post-operative  pain  relief  compared  to  currently
marketed formulations of bupivacaine.

● Secure  regulatory  approval  and  commercialize  our  products  in  the  United  States  either  ourselves  or  through  partnership  or  licensing
arrangements with other pharmaceutical companies, and globally through licensing arrangements with pharmaceutical companies.  We  hold
worldwide  commercialization  rights  to  LIQ861  and  LIQ865.  We  are  currently  exploring  opportunities  to  commercialize  LIQ861  in  the  United
States,  subject  to  receiving  regulatory  approval,  either  by  ourselves  or  through  partnership  or  licensing  arrangements  with  other  pharmaceutical
companies. With respect to LIQ865, after reviewing the results of all of our Phase 2-enabling toxicology studies, and subject to the availability of
sufficient  funding,  we  plan  to  evaluate  whether  to  pursue  continued  internal  development  or  to  explore  licensing  arrangements  with  other
pharmaceutical  companies.  Outside  of  the  United  States,  we  intend  to  pursue  the  regulatory  approval  and  commercialization  of  LIQ861  and
LIQ865 through licensing arrangements with pharmaceutical companies with regional expertise.

● Expand  our  internal  pipeline  leveraging  our  PRINT  technology.  We  intend  to  continue  targeting  diseases  where  we  believe  our  PRINT
technology  can  improve  the  efficacy,  safety  and  patient  experience  of  current  treatments  that  have  been  impaired  by  suboptimal  drug  product
formulation and delivery. We plan to focus initially on the development of improved and differentiated drug products containing FDA-approved
active pharmaceutical ingredients, or APIs, with proven efficacy and safety profiles eligible to use the 505(b)(2) regulatory pathway. In addition,
we may expand our clinical development of LIQ861 and LIQ865, where appropriate, into broader indications or new applications.

● Pursue  strategic  collaborations  to  maximize  the  value  of  products  enabled  by  PRINT  technology.  In  addition  to  advancing  our  own  internal
product candidates, we have collaborated, and may consider collaborating, with pharmaceutical companies to develop their own product candidates
across  a  wide  range  of  therapeutic  areas,  molecule  types  and  routes  of  administration,  leveraging  our  PRINT  technology.  We  believe  that
collaborating with pharmaceutical companies helps advance new PRINT capabilities, while adding to our intellectual property portfolio.

Our Competitive Strengths

We believe that we have several key strengths that have contributed to the development of our business and that will help us to realize our goal of becoming
a biopharmaceutical company across research, development and commercialization activities. Our competitive strengths include:

● Our PRINT technology gives us the capability to overcome the constraints of conventional formulation and production methods and can be
applied broadly across therapeutic areas, molecule types and routes of administration. Our PRINT technology allows us to precisely engineer
drug particles in a wide variety of compositions, sizes and shapes and achieve a high level of control over the physical and chemical characteristics
of  drug  particles,  as  compared  to  conventional  formulation  and  production  methods.  PRINT  particles  can  be  designed  to  address  specific
pharmacological  or  therapeutic  objectives,  such  as  enhancing  the  route  of  administration,  improving  solubility,  enhancing  stability  or  extending
therapeutic effects. Using our PRINT technology, we are able to engineer, among others, small molecule and biologic particles, single agent drug
and  combination  drug  particles  and  vaccine  particles  to  improve  efficacy,  safety  and  convenience  for  patients.  Our  internal  pipeline  strategy  is
currently focused on developing proprietary innovations to currently approved drug products in order to minimize development risks and increase
speed to market. In particular, we have designed LIQ861 to maximize the therapeutic benefits of treprostinil in treating PAH by safely delivering
higher doses into the lungs using a convenient, palm-sized DPI. We believe that this may lead to a more attractive product profile with a more
convenient method of administering the drug, as compared to the currently available inhaled therapies. We have also designed LIQ865 with the
intention of providing patients with local post-operative analgesia for three to five days. We believe this would provide a longer period of pain
relief  than  the  currently  available  local-acting  pain  drugs  and  thereby  reduce  reliance  on  opioids  and  non-steroidal  anti-inflammatory  drugs,  or
NSAIDs, for local post-operative pain management.

● We have scaled operations with rapid and cost-effective transition to clinical development and commercial production. We believe our research
and development operations and PRINT technology allow us to transition rapidly and cost-effectively from laboratory to clinical development and
ultimately commercial-scale manufacture of drug particles. Utilizing well-established techniques from other roll-to-roll manufacturing processes,
we have scaled PRINT technology to support the quality and quantity needs for clinical and, we believe, commercial production of our product
candidates.  The  manufacturing  equipment  for  the  PRINT  technology  requires  a  relatively  small  footprint,  low  capital  investment  and  minimal
operating costs. We believe our manufacturing facilities comply with the FDA’s current good manufacturing practices, or cGMP, requirements.

● We have a strong proprietary position through a combination of patents, trade secrets, proprietary know-how and licensing arrangements. We
protect our PRINT technology and the resulting engineered particles through a combination of patents, trade secrets, proprietary know-how and
licensing arrangements. We have an active patent strategy that covers major geographic markets, including the United States, Europe and Japan. As
of  December  31,  2019,  our  patent  portfolio,  which  includes  patents  and  patent  applications  we  own  or  co-own,  as  well  as  patents  and  patent
applications we have licensed from third parties, such as the University of North Carolina at Chapel Hill, or UNC, comprises 127 issued patents
and 32 pending patent applications worldwide. As we develop new product candidates, either independently or with collaborators, we will seek
additional patent protection.

● We have strong capabilities in pharmaceutical research and clinical development. Our research and development team includes 22 employees as
of  December  31,  2019,  led  by  our  senior  management,  and  has  extensive  experience  in  clinical  development  and  pharmaceutical  research  and
development activities in our specific areas of research interest.

● We  have  a  seasoned  management  team.  Our  management  team  includes  industry  veterans  with  significant  experience  in  drug  discovery,
development  and  commercialization.  Members  of  our  leadership  team  have  worked  across  different  segments  of  the  pharmaceutical  industry,
including branded and generic pharmaceuticals, medical devices and manufacturing services. Prior to joining us, our Chief Executive Officer and
director,  Neal  Fowler,  served  as  president  of  Centocor,  Inc.,  a  subsidiary  of  Johnson  &  Johnson  that  is  focused  on  the  development  and
commercialization  of  biomedicines  used  to  treat  chronic  inflammatory  diseases.  Additionally,  our  Chief  Operations  Officer,  Robert  Lippe,
previously served as executive vice president of operations and chief operations officer at Alexza Pharmaceuticals, Inc. Furthermore, our Senior
Vice President, Product Development, Dr. Robert Roscigno, previously served as the president and chief operating officer of Lung Rx, Inc., where
he  was  a  member  of  the  team  responsible  for  bringing  Tyvaso  through  Phase  3  development,  and  held  multiple  leadership  positions  at
United Therapeutics and its subsidiaries, where he contributed to the successful development and worldwide commercialization of Remodulin™, a
parenteral formulation of treprostinil. We believe that the experience of these individuals and other members of our management team enables us to
evaluate opportunities and build collaboration arrangements that match the breadth of the potential applications for our PRINT technology.

Our Product Candidates

LIQ861

Our  lead  product  candidate,  LIQ861,  is  an  inhaled  dry  powder  formulation  of  treprostinil  designed  using  our  PRINT  technology  to  enhance  deep-lung
delivery  using  a  convenient  DPI  for  the  treatment  of  PAH.  We  believe  LIQ861  can  overcome  the  limitations  of  current  inhaled  therapies  and  has  the
potential  to  maximize  the  therapeutic  benefits  of  treprostinil  in  treating  PAH  by  safely  delivering  higher  doses  into  the  lungs.  If  approved,  we  believe
LIQ861 will have the potential to increase the number of patients using the inhaled route of administration for PAH by providing the benefits of inhaled
prostacyclin therapy earlier in a patient’s disease progression as well as delaying the burden of starting continuously infused agents.

Background on PAH

PAH is a chronic, progressive disease caused by hardening and narrowing of the pulmonary arteries that can lead to right heart failure and eventually death.
Prostacyclin  is  a  vasoactive  mediator  essential  to  normal  lung  function  that  is  deficient  in  patients  with  PAH.  With  PAH,  the  elevated  pressure  in  the
pulmonary arteries strains the right side of the heart as it pumps blood to the lungs. The extra stress causes the heart to enlarge and become less flexible,
compromising its ability to pump blood through the lungs and to the rest of the body. PAH initially presents as exertional dyspnea, lethargy and fatigue and
may be confused with other disease states with similar symptoms. PAH often goes undiagnosed or misdiagnosed until symptoms become severe, with the
mean time from onset of symptoms to correct diagnosis being more than two years in the United States. As PAH progresses and right ventricular failure
develops,  exertional  chest  pain,  or  angina,  exertional  syncope  and  peripheral  edema  may  develop.  Following  confirmation  of  the  diagnosis  based  on
hemodynamic parameters, treatment is recommended to lower pulmonary arterial pressures and treat the symptoms of PAH.

PAH  is  part  of  a  larger  classification  of  pulmonary  hypertension,  or  PH,  which  is  divided  into  five  groups  based  on  the  criteria  of  the  World  Health
Organization, or WHO, as defined at the 5th World Symposium on Pulmonary Hypertension. WHO Group I is comprised of individuals with PAH.

PAH is a rare disease, with an estimated prevalence in the United States of approximately 30,000 patients. The mean age of diagnosis is 50 years according
to both French and U.S. registries, with more women being diagnosed with PAH than men. Patients may have idiopathic PAH, in which no underlying cause
can be determined, or a heritable form of the disease. A large number of PAH patients also have associated comorbidities such as congenital heart disease,
HIV, connective tissue diseases like scleroderma, liver diseases, systemic hypertension, obesity, clinical depression, non-PAH related obstructive airways,
sleep apnea and diabetes.

Due to delayed diagnosis, many patients already have an advanced form of PAH, requiring aggressive treatment combining multiple classes of therapy. The
severity of PAH may be classified according to the heart failure guidelines of the NYHA based on the degree of limitation of physical activity and described
by the American Heart Association as follows:

● NYHA  Class  I  —  No  limitation  of  physical  activity.  Ordinary  physical  activity  does  not  cause  undue  fatigue,  palpitation  or  dyspnea,  which  is

shortness of breath.

● NYHA Class II — Slight limitation of physical activity. Comfortable at rest. Ordinary physical activity results in fatigue, palpitation or dyspnea.

● NYHA Class III — Marked limitation of physical activity. Comfortable at rest. Less than ordinary activity causes fatigue, palpitation or dyspnea.

9

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● NYHA  Class  IV  —  Unable  to  carry  on  any  physical  activity  without  discomfort.  Symptoms  of  heart  failure  at  rest.  If  any  physical  activity  is

undertaken, discomfort increases.

As the disease progresses, these symptoms cause a significant negative impact on quality of life, limiting the ability to perform common daily activities,
including work, travel and previous hobbies. Patients also describe the emotional toll of PAH, including fear, frustration, embarrassment and stigma. The
burden of care associated with currently available treatments can add further logistical and emotional burden to the patients.

Current Therapies and Their Limitations

There is currently no cure for PAH. The goals of existing treatments are to alleviate symptoms, maintain or improve NYHA functional class, delay disease
progression and improve quality of life. Inhaled therapies are generally prescribed for, but not limited to, patients in NYHA Class II and Class III. Approved
drugs target three distinct molecular pathways that have been implicated in the disease process: the prostacyclin pathway, the nitric oxide pathway and the
endothelin  pathway.  Drugs  targeting  each  of  these  pathways  are  used  alone  or  in  combination  with  each  other  to  treat  patients  with  PAH.  Prostacyclin
deficiency in the lung is a central dysfunction in PAH, but can be supplemented with prostacyclin analogs. Prostacyclin deficiency can also be managed
with a recently approved selective IP prostacyclin receptor agonist, selexipag. Nitric oxide deficiency can be treated with phosphodiesterase-5, or PDE5,
inhibitors,  which  target  a  specific  enzyme,  increasing  vasodilation.  Endothelin  overexpression  in  PAH  patients  causes  vasoconstriction  of  pulmonary
vasculature, but can be treated with endothelin receptor antagonists, or ERAs. Many physicians start their PAH patients on oral PDE5 inhibitors, oral ERAs
or both. Drugs targeted to the prostacyclin pathway are usually added to these oral therapies, but can be used alone.

Drugs  targeting  the  prostacyclin  pathway  are  central  to  PAH  therapy.  Prostacyclin  is  essential  to  normal  lung  function.  In  healthy  people,  prostacyclin,
which is a vasoactive mediator, is continually released by the lungs into the pulmonary arterial circulation, where it affects the regulation of vascular tone,
including through direct vasodilation of pulmonary arteries, inhibition of the proliferation of smooth muscle cells within arteries and inhibition of platelet
aggregation. To supplement the deficiency of prostacyclin in patients with PAH, several prostacyclin analogs have been developed including epoprostenol,
which  is  administered  intravenously;  treprostinil,  which  can  be  administered  intravenously,  subcutaneously  or  in  nebulized  or  oral  formulations;  and
iloprost,  which  can  be  administered  intravenously  or  in  nebulized  form.  A  new  class  of  drugs  called  selective  IP  prostacyclin  receptor  agonists  help
stimulate some of the mechanisms that would otherwise be promoted by prostacyclin or an analog. Selexipag, an oral agent, is the only approved drug in
this new class.

The goal of treatment targeting the prostacyclin pathway is to maximize a patient’s exposure to the highest tolerable level of drug. Prostacyclin analogs, like
treprostinil, have been developed for continuous infusion, either intravenously or subcutaneously, inhalation using a nebulizer and oral administration in the
form of tablets. The maximal efficacy benefit of any one drug in the prostacyclin pathway is partially limited by its specific safety profile. Drugs exerting
their effect through the prostacyclin pathway, including oral treprostinil and IP prostacyclin receptor agonists such as selexipag, are limited by side effects
from binding of the drug to receptors in non-targeted tissues, such as the gastrointestinal tract and nerves, which can cause diarrhea, nausea and jaw pain.
Nebulized  solutions  can  have  side  effects  including  cough,  upper  airway  irritation  and  pain  caused  by  their  topical  irritant  properties,  which  limits  the
amount of drug that can be given to the patient. As the disease progresses, patients require continuous prostacyclin infusion to maximize drug exposure.
However, infusion pumps can cause side effects related to infusion site pain and risk of infection, while also adversely affecting quality of life.

Delivering  prostacyclin  analogs  locally  to  the  lungs  by  inhalation  has  been  effective  and  causes  fewer  systemic  side  effects.  Inhalation  of  prostacyclin
analogs  supplements  the  endogenous  production  of  prostacyclin  where  it  is  normally  synthesized,  near  the  targeted  pulmonary  arteries.  As  a  result,
inhalation of prostacyclin analogs helps avoid side effects related to off-target tissues and takes advantage of binding key prostacyclin receptors that are
preferentially expressed in the lung. The only inhaled prostacyclin analogs approved by the FDA are Tyvaso and Ventavis, which both require nebulizers.

10

 
 
 
 
 
 
 
 
 
 
Tyvaso (treprostinil) is approved in the United States and Israel, but is not approved in Europe and Japan. Tyvaso is indicated for the treatment of PAH to
improve  exercise  ability.  The  maximum  recommended  dose  of  Tyvaso  is  54  mcg,  delivered  four  times  daily  from  a  proprietary  nebulizer,  requiring
nine breaths for each dose. In a long-term open-label extension study of Tyvaso, patients continued treatment for a mean duration of 2.3 years, with 89% of
patients achieving the target dose of 54 mcg, delivered in nine breaths, and 42% achieving a dose of 72 mcg, delivered in 12 breaths. It has been reported
that more than 80% of PAH patients on inhaled therapy in the United States use Tyvaso. United Therapeutics reported approximately $415 million in sales
of Tyvaso in 2019.

Ventavis (iloprost) is approved in the United States, Europe and Japan. Ventavis is a synthetic analog of prostacyclin indicated for the treatment of PAH to
improve a composite endpoint consisting of exercise tolerance, symptoms and lack of deterioration. Ventavis is administered with a proprietary nebulizer six
to nine times per day during waking hours, no more than once every two hours, and takes six to ten minutes to administer per use.

Tyvaso and Ventavis both require the use of proprietary nebulizers. Patients must follow specific instructions to set up and operate the device, clean the
device daily, locate a power source or use a battery to operate the device, and carry the device and its associated accessories around in a large carrying case,
along with distilled water, to administer the treatment throughout the day. As a result, the use of these approved inhaled prostacyclin therapies is typically
limited  to  patients  who  have  not  responded  to  oral  medications  that  target  the  three  pathways.  Current  medical  practice  is  to  add  an  inhaled  drug  to  the
patient’s existing oral ERA and/or PDE5 treatment regimen, rather than withdrawing the oral drug upon initiation of the inhaled drug.

Potential Benefits of Our Approach

We believe LIQ861 can overcome the limitations of current nebulized therapies and has the potential to maximize the therapeutic benefits of treprostinil in
treating PAH by safely delivering higher doses into the lungs using a convenient, palm-sized DPI. In our clinical trials, LIQ861 has been well-tolerated at
doses  approximately  twice  as  high  as  the  maximum  recommended  dosage  of  Tyvaso.  These  higher  doses  of  inhaled  dry  powder  treprostinil  can  also  be
administered in one to four breaths, compared to nine breaths for the maximum recommended dose of Tyvaso. Additionally, we believe LIQ861 may have
the potential to improve overall patient adherence by offering the convenience of a discrete, palm-sized DPI. In our market research, patients expressed a
preference for a DPI product, noting that it can fit easily into a purse, minimize hassle while traveling and reduce the breaths and time associated with their
current nebulized treatments.

The advantages of the LIQ861 product profile are enabled by our PRINT technology. Each LIQ861 particle is designed to enhance delivery and deep-lung
penetration.  LIQ861  particles  are  a  precise  size  and  highly  uniform  shape,  since  particles  are  formed  from  mold  cavities  that  exactly  match  each  other.
Competing technologies, such as spray-drying, create particles that have a broader variation in size and shape. As a result, particles farther from the mean
target size would be too large or too small to reach the intended location in the deep-lung.

Inspired by a naturally occurring pollen, LIQ861 PRINT particles have a one micrometer trefoil-shape measured by an inscribed one micrometer circle as
shown in the figure below. In vitro studies suggest that the uniformity of size and shape allow our inhaled particles to target delivery into the lungs with less
deposition in the upper airways. Our independent control of the parameters of drug particles has enabled us to create the first clinically tested therapeutic
that stabilizes treprostinil in an inhaled dry powder formulation.

The figures below depict LIQ861, with the figure on the left showing size and shape consistency among particles and the figure on the right showing their
trefoil shape:

LIQ861 is administered using the RS00 Model 8 DPI, which is manufactured by Plastiape S.p.A. This device and its variants have been used in at least eight
marketed products globally since 2001, including Novartis’s Foradil Aerolizer® for the treatment of asthma and chronic obstructive pulmonary disease, or
COPD.

The picture below shows the DPI used to administer LIQ861:

Clinical Development

The INSPIRE study was designed to evaluate patients who have either been under stable treatment with nebulizer-delivered treprostinil for at least three
months  and  are  transitioned  to  LIQ861  under  the  protocol  or  who  have  been  under  stable  treatment  with  no  more  than  two  non-prostacyclin  oral  PAH
therapies for at least three months and have their treatment regimen supplemented with LIQ861 under the protocol. The primary objective of the study was
to evaluate the long-term safety and tolerability of LIQ861.

In the United States, we submitted  an NDA under the 505(b)(2) regulatory pathway in January 2020. The 505(b)(2) pathway allows us to rely, in part, on
the FDA’s prior conclusions of efficacy and safety for Tyvaso, and the active ingredient treprostinil (which has been the active ingredient in several different
products, in total, approved by the FDA, with routes of administration including continuous infusion, inhaled and oral routes).

Clinical Development

We have developed LIQ861 under the 505(b)(2) regulatory pathway, which allows for an accelerated development program based upon establishing safety,
tolerability, and comparative bioavailability to a reference listed drug, which for LIQ861 is Tyvaso. Our clinical development program has consisted of two
principal  studies.  The  first  of  these  was  a  Phase  1  study  in  healthy  volunteers  that  was  designed  to  assess  the  safety,  tolerability  and  pharmacokinetic
parameters of LIQ861 in healthy volunteers. After an end of Phase 1 meeting with the FDA, we proceeded directly to a pivotal Phase 3 study, without being
required  to  conduct  a  Phase  2  study.  In  addition,  we  conducted  two  supplementary  pharmacokinetic  studies  in  healthy  volunteers.  The  results  of  these
studies, which serve as the basis for our NDA submission, are described below.

Phase 1 Trial

We  conducted  a  randomized,  placebo-controlled,  double-blind,  Phase  1  trial  in  57  healthy  volunteers  to  assess  safety,  tolerability  and  pharmacokinetics
following a single administration of LIQ861 at treprostinil capsule strengths between 25 mcg and 150 mcg. The subjects were enrolled into six dose cohorts.
Within each dose cohort, subjects were randomized to receive LIQ861 or a placebo.

Dose Selection

For  the  first-in-human  study,  the  initial  dose  for  LIQ861  was  chosen  based  on  the  indicated  dosing  for  the  reference  listed  drug,  Tyvaso.  Independent
investigations of particle emission using the RS00 Model 8 DPI and simulated inspiration of the bulk powder from a nebulizer led to a projection that a
25 mcg treprostinil capsule strength of LIQ861 dry powder inhalation would result in approximately similar treprostinil administration as three breaths of
Tyvaso, or 18 mcg of treprostinil, the lowest approved dose through nebulization. The following table shows the doses of LIQ861 tested along with our
estimate of the equivalent Tyvaso dose.

(1)

LIQ861 capsule treprostinil strength doses between 25 mcg and 100 mcg are single capsules. LIQ861 capsule treprostinil strength doses of
125  mcg  and  150  mcg  are  two  capsules,  but,  if  approved,  they  could  be  developed  as  single  capsules  and  therefore  only  require  one  to
two breaths.

(2)

Tyvaso (treprostinil) full prescribing information: initial dosage: 3 breaths (18 mcg); maximum recommended dosage: 9 breaths (54 mcg).

Our  conclusion  from  this  study  is  that  the  capsule  strength  of  75  mcg  of  LIQ861  is  approximately  equivalent  to  the  maximum  recommended  dose  of
54 mcg, or nine breaths, of Tyvaso, and the capsule strength of 150 mcg of LIQ861 is approximately double the maximum recommended dose of Tyvaso.

Safety and Tolerability

In the Phase 1 clinical trial, we escalated the treprostinil capsule strength of LIQ861 progressively from 25 mcg to 150 mcg. There were no dose-limiting
toxicities at the highest dose evaluated. We noted no serious adverse events and all reported treatment-emergent adverse events, or TEAEs, related to the
treatment were mild. The most frequent adverse event reported by subjects receiving LIQ861 was mild cough and throat irritation.

13

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We  did  not  observe  a  proportional  increase  of  adverse  events  as  the  treprostinil  capsule  strengths  were  escalated  from  25  mcg  to  100  mcg.  No  adverse
events were observed in subjects who received the placebo PRINT particles that contained only excipients.

Pharmacokinetics

In the Phase 1 trial, the LIQ861 plasma levels increased proportionally as the dosage of LIQ861 increased, as shown in the graph below. At higher doses,
50% of subjects receiving LIQ861 had measurable treprostinil levels after four hours, which could indicate the potential to minimize symptoms between
dosing cycles.

The pharmacokinetic parameters in the table below were estimated from plasma samples. Nominal elapsed time from dosing was used to estimate all
individual pharmacokinetic parameters, including:

● Cmax         Maximum observed plasma concentration;

● Tmax         Time of maximum concentration;

● T1/2          Terminal-phase half-life; and

● AUCInf    Area under the plasma concentration-time curve.

14

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Plasma levels of LIQ861, as determined by the area under the curve, which is a pharmacokinetic measurement of drug exposure in blood plasma over time,
and  the  maximum  concentration  were  similar  to  the  data  used  in  connection  with  the  approval  of  Tyvaso,  as  reported  in  the  FDA  Summary  Basis  of
Approval  for  Tyvaso.  LIQ861  also  had  a  half-life  in  the  blood  similar  to  such  data.  These  results  suggest  that  our  formulation  has  not  changed  the
pharmacokinetic profile of inhaled treprostinil.

Non-Clinical Studies

The  pharmacology,  pharmacokinetics  and  toxicology  of  treprostinil  are  well  understood,  having  previously  been  characterized  to  support  approval  of
Remodulin,  which  is  treprostinil  administered  through  subcutaneous  or  intravenous  infusion,  Orenitram®,  which  is  treprostinil  administered  through
extended-release tablets, and Tyvaso, which is treprostinil inhaled through a proprietary nebulizer. We plan to rely in part on the data used in support of
FDA approval of these treatments, in addition to our own toxicity studies, to support the development and approval of LIQ861.

In October 2016, we completed a 14-day, repeat dose, inhalation toxicity study in rats to support the Phase 1 trial. In August 2017, we completed a 26-week
toxicology  study  in  rats.  In  rats,  pharmacokinetic  profiles  at  the  end  of  14  days  of  LIQ861  treatment  were  generally  similar  to  those  seen  with  inhaled
nebulized treprostinil delivered at similar treprostinil dose levels. Following 26 weeks of daily dosing, treprostinil exposure was slightly higher in LIQ861-
treated rats. The results from this study supported chronic outpatient dosing of LIQ861 in patients with PAH in our Phase 3 trial.

Pivotal Phase 3 INSPIRE Trial

In August 2019, we completed an open-label Phase 3 clinical trial, INSPIRE, or Investigation of the Safety and Pharmacology of Dry Powder Inhalation of
Treprostinil, for LIQ861. The study was conducted at multiple sites in the United States. The primary objective of the INSPIRE study was to evaluate the
long-term safety and tolerability of LIQ861.

The study was designed to evaluate patients who have either been under stable treatment with Tyvaso (nebulizer-delivered treprostinil), for at least three
months and were transitioned to LIQ861 under the protocol, or Transition patients, or patients who had been under stable treatment with no more than two
non-prostacyclin oral PAH therapies for at least three months and then had their treatment regimen supplemented with LIQ861 under the protocol, or Add-
On patients. Transition patients were initiated at a capsule strength of LIQ861 lower than their current stable treprostinil dose administered four times daily,
while Add-on patients were initiated at 26.5 mcg dose, also administered four times daily. In both cases, LIQ861 was uptitrated in 26.5 mcg treprostinil
incremental  doses  to  symptom  relief  or  the  limit  of  tolerance.  Within  the  INSPIRE  study,  18  Transition  patients  were  evaluated  in  a  one-directional
crossover sub-study comparing bioavailability and pharmacokinetics, or PK, of treprostinil following dosing of LIQ861 as compared with Tyvaso.

In March 2019, we reported that we had completed enrollment and met the primary endpoint, which was long-term safety and tolerability, in our INSPIRE
trial. LIQ861 was observed to be well-tolerated in 109 patients, with 101 patients (93%) completing at least two months of treatment. During the two-month
period, LIQ861 was evaluated at doses up to 159 mcg with no study-drug related serious adverse events. Dosing has exceeded 159 mcg in some patients
receiving drug beyond the Month 2 time point. We have not yet determined a maximum tolerated dose of LIQ861. We also reported fully enrolling our one-
directional crossover sub-study comparing bioavailability and PK of treprostinil as sub-study patients transitioned from Tyvaso to LIQ861.

In April 2019, we reported further data from these 109 patients in our INSPIRE trial on exploratory endpoints at two months of treatment that demonstrated
generally  favorable  results  with  respect  to  six-minute  walk  distance  and  quality  of  life  as  indicated  by  the  Minnesota  Living  with  Heart  Failure
Questionnaire, or MLHFQ. In May 2019, we reported further presentation of this data at the ATS International Conference 2019.

In June 2019, we reported results from the INSPIRE study indicating that the 79.5 mcg dose of LIQ861 correlates with the 54 mcg dose of Tyvaso (nine
breaths), the maximum recommended label dose of Tyvaso. Analysis of the data from the PK sub-study in patients showed variability in systemic plasma
levels of both LIQ861 and Tyvaso, which is believed to be attributed to variation in severity of disease and has been seen in prior studies of treprostinil in
patients. To more accurately characterize the PK of LIQ861, we conducted two additional PK studies in healthy volunteers. In the first of these studies, we
observed  unexpected  variability  in  PK  levels.  Post-hoc  analysis  showed  that  plasma  levels  of  treprostinil  were  tightly  correlated  to  the  LIQ861  dose
delivered. Based upon additional non-clinical and clinical work, we believe the unexpected variability seen in this healthy volunteer study was due to an
administration technique unique to the conduct of the study in the Phase 1 setting. In August 2019, we completed a second PK study in healthy volunteers in
which  the  proper  administration  technique  was  followed.  This  study  demonstrated  significantly  reduced  variability,  and  we  believe  we  have  established
comparative bioavailability to the reference listed drug. The results of this second supplementary PK study in healthy volunteers are described more fully
below.

Final enrollment in the pivotal INSPIRE trial included 121 PAH patients to assess safety and tolerability through Month 2, the primary endpoint of the trial.
Of  the  121  patients  enrolled  in  the  study,  55  were  Transition  patients  and  66  were  Add-On  patients.  Add-On  patients  started  on  a  dose  of  26.5  mcg  of
LIQ861, with most (>80%) titrating to a 79.5 mcg dose or higher within the first two months of treatment. Consistent with preliminary data presented in the
second quarter of 2019, LIQ861 was observed to be well-tolerated and treatment-emergent adverse events were mostly mild to moderate in nature at Month
2  up  to  doses  of  159  mcg  of  LIQ861,  the  highest  dose  studied  at  Month  2.  Durability  of  therapy  with  LIQ861  appeared  to  be  favorable,  with  96%  of
Transition patients and 91% of Add-On patients remaining on study drug at the Month 2 timepoint.

Initial  analysis  of  the  exploratory  endpoints  from  the  INSPIRE  study  indicates  that  LIQ861  may  provide  functional  and  quality-of-life  benefits  to  PAH
patients in New York Heart Association, or NYHA, functional classes II and III. More than 90% of all patients who completed two months of treatment
maintained or improved their NYHA functional class. Additionally, we observed improvement in six-minute-walk-distance and quality of life as measured
by the MLHFQ in both patient groups.

We continued to treat patients who chose to remain on LIQ861 beyond the Month 2 timepoint of the primary endpoint. More than 80% of INSPIRE patients
remained on study drug at Month 4 with no significant changes in safety or tolerability observed compared to Month 2. At the completion of the INSPIRE
study, the patient with the longest duration of treatment had been on LIQ861 therapy for 18 months. To provide for continuity of treatment, patients from
INSPIRE were provided the opportunity to continue receiving treatment in an extension study, which is currently ongoing.

Supplemental Pharmacokinetic Studies in Healthy Volunteers

To complement the pharmacokinetic data from our Phase 3 study, we conducted two additional PK studies in healthy volunteers. In the first of these studies,
we  observed  unexpected  variability  in  PK  levels.  Post-hoc  analysis  showed  that  plasma  levels  of  treprostinil  were  tightly  correlated  to  the  LIQ861  dose
delivered. Based upon additional non-clinical and clinical work, we believe the unexpected variability seen in this healthy volunteer study was due to an
administration technique unique to the conduct of the study in the Phase 1 setting. In August 2019, we completed a second PK study in healthy volunteers in
which  the  proper  administration  technique  was  followed.  This  study  demonstrated  significantly  reduced  variability,  and  we  believe  we  have  established
comparative bioavailability to the reference listed drug.

Subjects  in  this  second  PK  study,  an  open-label,  crossover  study  in  healthy  volunteers  age  18  to  45  years,  inclusive,  were  randomized  to  one  of  three
treatment sequences, with each sequence consisting of two periods. Each period and dose of LIQ861 and Tyvaso were separated by at least 24 hours. The
three treatment sequences, and the number of patients in each, are shown in the table below:

Sequence  1  assessed  the  reproducibility  of  plasma  treprostinil  levels  following  dosing  with  79.5  mcg  of  LIQ861.  Analysis  of  the  results  of  sequence  1
demonstrated  nearly  identical  PK  parameters  between  the  two  periods  with  low  variability.  Cmax,  mean  AUCinf  and  the  median  time  to  Cmax  (Tmax)
following a single dose of 79.5 mcg of LIQ861 were 1.25 ng/ml, 1.01 hr*ng/ml, and 0.17 hours, respectively.

Sequences 2 and 3 evaluated the rate and extent of treprostinil exposure following administration of a 79.5 mcg dose of LIQ861 compared with nine breaths
of  Tyvaso.  The  absorption  rate  was  comparable  between  LIQ861  and  Tyvaso,  with  peak  concentrations  achieved  at  approximately  0.13  and  0.17  hours
(median Tmax) post inhalation for LIQ861 and Tyvaso, respectively. Following peak concentrations, mean plasma concentrations of treprostinil decreased
in  a  monophasic  manner  with  a  similar  rate  of  elimination  for  both  treatments  (approximate  mean  half-life  of  0.5  hours  for  LIQ861  and  Tyvaso).  The
comparative bioavailability of treprostinil, as assessed by the geometric mean ratios (LIQ861/Tyvaso) were 0.923, 0.941, and 0.931 for AUCinf, AUClast
and Cmax, respectively, and the 90% confidence intervals for these ratios were within the acceptable equivalence limits of 0.80 to 1.25:

This study provided additional data to support our belief that the bioavailability and systemic exposures of treprostinil following a 79.5 mcg dose of LIQ861
and nine breaths of Tyvaso are comparable.

NDA Submission

Based upon the encouraging results of the INSPIRE trial and the supplemental healthy volunteer pharmacokinetics study, we submitted an NDA for LIQ861
to  the  FDA  in  January  2020.  Prior  to  submitting  the  NDA,  we  participated  in  a  pre-NDA  meeting  with  the  FDA  with  respect  to  the  chemistry,
manufacturing and controls, or CMC, aspects of the NDA and received no new CMC requirements from the FDA for the NDA submission. We had also
requested  a  pre-NDA  meeting  with  the  FDA  focused  on  clinical  and  nonclinical  contents  of  the  NDA.  Based  on  FDA’s  responses  to  our  questions  in
advance of the meeting, or the preliminary meeting comments, we no longer considered the meeting necessary, as we believe that the responses provided
sufficient feedback to inform our NDA submission plans.

Additional Clinical Trials

We intend to conduct additional clinical work during and beyond the NDA review period in order to generate additional data on LIQ861 and to support our
marketing  and  commercial  activities  in  advance  of  a  potential  launch  of  LIQ861,  including  maintaining  patients  on  LIQ861  up  to  our  U.S.  launch  and
conducting a clinical trial in pediatric patients. We also continue to conduct development work in support of potential approval and commercialization of
LIQ861, including label and patient-use assessments.

We are also currently conducting an additional clinical trial in Europe to study the hemodynamic effects of LIQ861 in PAH patients. Although the FDA has
not requested that we undertake this clinical trial, the data may help assess the effects of LIQ861 on acute and chronic hemodynamic measurements and
right heart function. Data from this clinical trial may also add to our understanding of safety, tolerability and pharmacokinetics of LIQ861.

Commercial Opportunity

An independent industry research firm estimated that sales for all major pulmonary hypertension drugs in 2019 would exceed $3.5 billion in the United
States. Approved therapies in the prostacyclin pathway may generate approximately $1.7 billion in sales in 2019, more than half of which would include the
prostacyclin analog treprostinil generated approximately $915 million from therapies formulated for continuous infusion, inhalation using a nebulizer and
oral delivery.

If approved, we believe LIQ861 would be the first inhaled dry powder formulation of treprostinil delivered using a convenient, palm-sized DPI. The dosing
regimens and patient experience for the two approved inhaled therapies compared to the expected product profile of LIQ861 are shown in the following
table.

Picture

Preferred choice within inhaled options. As reported in our market research, physicians and patients expressed a clear preference for the expected product
profile of LIQ861 over current nebulized therapies, primarily due to the ease and convenience of administration of LIQ861. Nebulized therapies require
more time and breaths than LIQ861, as well as daily and weekly assembly, disassembly and cleaning.

Attractive  switch  from  orals.  The  ease  and  range  of  dosing  of  LIQ861  may  be  attractive  to  patients  who  are  in  earlier  stages  of  the  disease,  but  poorly
managed  on  oral  prostacyclin  products.  Local  delivery  of  treprostinil  to  the  lung  offers  fewer  systemic  side  effects.  However,  we  believe  some  of  these
patients are hesitant to switch to more burdensome nebulized options.

Delay transition to continuous infusion. We are investigating a wide range of LIQ861 doses in order to maximize patient exposure to treprostinil, a key
factor  in  the  efficacy  of  prostacyclin  analogs.  In  our  clinical  trials,  LIQ861  was  well  tolerated  at  levels  that  we  estimate  are  approximately  twice  the
maximum recommended dose of Tyvaso. We believe the dose range enabled by LIQ861 would allow patients to titrate to higher levels of treprostinil and
potentially extend the time on inhaled therapy, delaying the eventual transition to continuous infusion.

Expand beyond WHO Group I patients (PAH). Prostacyclin  based  therapies  have  only  been  approved  for  WHO  Group  I  patients.  However,  prostacyclin
analogs may have utility in the treatment of PH in other categories, as suggested by current off-label use in WHO Group III, which includes individuals with
pulmonary  hypertension  secondary  to  lung  diseases  or  hypoxemia,  and  WHO  Group  IV,  which  includes  individuals  with  chronic  thromboembolic
pulmonary hypertension. Although we have no current plans to study LIQ861 in PH patients outside of WHO Group I, we will continue to monitor the
investigations conducted by other companies and independent investigators of prostacyclin analogs, especially Tyvaso, and, if appropriate, may consider
initiating studies with LIQ861 in patient populations where such agents have been shown to have a therapeutic benefit. In one such recently reported study,
United Therapeutics reported positive data in a Phase 3 trial of Tyvaso in a subpopulation of WHO Group III patients with interstitial lung disease, with an
estimated prevalence of 30,000 patients in the United States. By 2025, the diagnosed prevalence of all WHO Group III sub-types is expected to grow to over
250,000 patients in the United States, 5EU and Japan. WHO Group IV includes patients diagnosed with chronic thromboembolic pulmonary hypertension,
or  CTEPH.  While  considered  underdiagnosed  and  undertreated,  the  current  estimates  for  diagnosed  prevalence  of  CTEPH  are  between  2,000  and  6,500
patients in the United States and more than 10,000 patients in the 5EU and Japan.

Competition in PAH

If approved for marketing, we expect that LIQ861 will face competition from the following inhaled treprostinil therapies that are either currently marketed
or in clinical development:

● Tyvaso,  or  inhaled  treprostinil,  marketed  by  United  Therapeutics,  has  been  approved  for  the  treatment  of  PAH  in  the  United  States  since  2009.
Tyvaso is administered via a proprietary nebulizer four times per day. Tyvaso is the reference listed drug in our NDA for LIQ861. Following patent
litigation,  United  Therapeutics  and  Watson  Pharmaceuticals,  Inc.,  or  Watson  Pharmaceuticals,  reached  a  settlement  whereby  Watson
Pharmaceuticals will be permitted to enter the market with a generic version of Tyvaso beginning on January 1, 2026.

● Ventavis, or inhaled iloprost, marketed in the United States by Actelion Pharmaceuticals Ltd, or Actelion, a division of Johnson & Johnson, and in
Europe by Bayer Schering Pharma AG., has been approved for the treatment of PAH in the United States since 2004. Ventavis is administered via a
proprietary nebulizer six to nine times per day.

● TreT, an inhaled formulation of treprostinil which United Therapeutics licensed from MannKind Corporation, or MannKind, is currently in late-
stage  clinical  development  in  the  United  States  for  the  treatment  of  PAH.  Under  the  license  agreement,  United  Therapeutics  is  responsible  for
global  development,  regulatory  and  commercial  activities.  MannKind  will  manufacture  clinical  supplies  and  initial  commercial  supplies  of  the
product while long-term commercial supplies will be manufactured by United Therapeutics. In September 2019, United Therapeutics commenced a
clinical  study  (BREEZE)  to  evaluate  the  safety  and  pharmacokinetics  of  switching  PAH  patients  from  Tyvaso  to  TreT  and  announced  plans  to
commence a second clinical study during the first half of 2020 to compare the pharmacokinetics of TreT to Tyvaso in healthy volunteers. United
Therapeutics further reported that the two studies, if successful, are the only clinical studies necessary to support FDA approval.

In  addition  to  these  other  inhaled  treprostinil  therapies,  we  expect  that  LIQ861  will  also  face  competition  from  other  treprostinil-based  drugs,  including
Orenitram,  which  is  administered  orally,  and  Remodulin,  which  is  administered  parenterally,  both  of  which  are  marketed  by  United  Therapeutics.  Other
agents  that  utilize  the  prostacyclin  pathway  include  parenteral  epoprostenol,  which  is  marketed  by  multiple  companies  as  generic  and  branded  products.
Because parenteral agents are considered to offer the greatest efficacy, but also carry the most significant side effects related to infusion site pain, risk of
infection, and significant limitations on quality of life, they are usually reserved for patients later in the course of the disease.

In addition to therapies based upon prostacyclin analogues, other classes of therapeutic agents for the treatment of PAH, all of which are delivered orally,
include the following:

● IP-agonists,  such  as  selexipag,  marketed  by  Actelion,  and  ralinepeg,  licensed  from  Arena  Pharmaceuticals  by  United  Therapeutics,  which  is

currently in clinical development;

● PDE-5 inhibitors, such as tadalafil, marketed by United Therapeutics, and sildenafil, marketed by Pfizer. Generic versions of both tadalafil and

sildenafil are currently available.

● Endothelin receptor antagonists, such as bosentan and macitentan, both marketed by Actelion, and ambrisentan, marketed by Gilead Sciences,

Inc. Generic version of bosentan and ambrisentan are currently available.

● Soluble guanylate cyclase (sGC) stimulator, such as riociguat marketed by Bayer.

20

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In  addition,  we  are  also  aware  of  several  agents  currently  in  clinical  development  in  the  United  States  for  the  treatment  of  PAH,  including  those  in
development by Insmed Inc. and Acceleron Pharma, Inc.

In addition to use in patients who have typically been treated with inhaled agents, we believe that LIQ861 may provide an attractive therapeutic option for
patients who are in earlier stages of the disease, but poorly managed on oral prostacyclin analogues. Additionally, we believe that because of the ability to
provide  higher  doses  of  treprostinil  with  LIQ861,  patients  may  be  able  to  remain  on  LIQ861  longer  before  initiating  parenteral  treprostinil  therapy  than
might be the case with other inhaled treprostinil therapies.

LIQ865

Our second product candidate, LIQ865, which is designed using PRINT technology, is an injectable, sustained-release formulation of bupivacaine, a non-
opioid pain medication for the management of local post-operative pain for three to five days through a single administration after a surgical procedure. If
approved,  we  believe  LIQ865  would  have  the  potential  to  provide  significantly  longer  local  post-operative  pain  relief  compared  to  currently  marketed
formulations of bupivacaine.

Background on Post-Operative Pain

The treatment of post-operative pain typically involves multi-modal therapy including the administration of local anesthetics after surgery. Although local
anesthetics  provide  a  well-established,  safe  and  efficacious  option  for  post-operative  pain  management,  the  duration  of  efficacy  for  conventional  local
anesthetics,  including  bupivacaine  and  lidocaine,  is  limited,  with  pain  relief  typically  lasting  for  eight  hours  or  less.  Because  post-operative  pain  may
continue to be severe for several days following surgery, additional therapies are required. These therapies include morphine and other opioids administered
orally or parenterally, as well as various non-opioids, including acetaminophen and NSAIDs, such as ibuprofen and ketorolac.

Current Therapies and Their Limitations

Opioids are the mainstay of post-operative pain management, but they are associated with a variety of potentially serious or life-threatening side effects such
as  sedation,  nausea,  constipation,  cognitive  impairment,  and  respiratory  depression.  In  addition,  opioids  may  be  administered  through  patient-controlled
analgesia systems, which may interfere with or delay patient ambulation and require significant hospital resources to implement and monitor. Furthermore,
exposure to opioids for as little as four days can lead to increased risk of chronic opioid use and addiction. The risk of opioid abuse has led physicians,
payors and the U.S. federal government to prioritize pain management strategies that minimize the use of opioids.

NSAIDs  and  other  non-opioids  for  pain  relief  in  the  post-operative  period  are  also  associated  with  various  side  effects,  including  bleeding  and
gastrointestinal and renal complications. Acetaminophen can cause liver injury or failure with excessive dosing. As a result, we believe there is demand
from healthcare providers and patients for post-operative pain relief therapies that can help prevent these issues.

Local  anesthetics  such  as  bupivacaine  hydrochloride,  or  Marcaine,  and  lidocaine  have  been  safely  used  for  post-operative  pain  for  decades,  but  have  a
duration of effect limited to less than eight hours. Approved in 2011, EXPAREL is a long-acting local anesthetic that involves an injection of bupivacaine in
a multivesicular liposome carrier at the surgical site and is marketed in the United States by Pacira Pharmaceuticals, Inc. Physicians report that EXPAREL
typically  provides  post-surgical  analgesia  for  only  24  to  36  hours  in  practice,  and  market  research  we  conducted  suggests  that  physicians  desire  longer
duration of effect to better manage local post-operative pain. In addition, because the interactions between the liposomal formulation of EXPAREL and co-
administered local anesthetics can result in rapid release of bupivacaine, co-administration of other local anesthetics is inadvisable.

21

 
 
 
 
 
 
 
 
 
 
 
 
Potential Benefits of LIQ865

Using our PRINT technology, we have developed a particle formulation of bupivacaine designed to improve the management of local post-operative pain.
We engineered the size and composition of LIQ865 particles to slowly release bupivacaine with the goal of providing patients with local pain relief for three
to  five  days  through  a  single  administration,  which  we  believe  would  provide  significantly  longer  local  post-operative  pain  relief  compared  to  currently
marketed formulations of bupivacaine. The figure below depicts LIQ865, showing size consistency among particles.

LIQ865  is  administered  as  a  suspension  and  is  easily  injected  at  the  surgical  site.  Because  the  molded  drug  particles  are  highly  stable,  we  believe  the
potential for dose dumping, the unintended rapid drug release of bupivacaine from the carrier, would be minimized with LIQ865. In a non-clinical study, co-
administration of LIQ865 with lidocaine did not cause early release of bupivacaine or otherwise negatively affect the pharmacokinetic profile of LIQ865.
LIQ865 was engineered to be rapidly reconstituted and administered by injection. Unlike other sustained-release formulations, we do not expect LIQ865
will  be  constrained  by  a  specific  ratio  of  drug  to  diluting  agent,  so  its  reconstitution  volume  can  be  adjusted  based  on  the  volume  needs  of  a  particular
procedure.  Furthermore,  because  particle-to-particle  uniformity  in  size  and  composition  is  key  to  determining  drug  release  rates,  the  uniformity  of  our
LIQ865 particles creates consistent release rates.

Non-Clinical Efficacy Studies

We commissioned an animal efficacy study of two formulations of LIQ865 in a rat perineural sciatic model, which was completed in January 2016. LIQ865
showed  an  extended  pharmacokinetic  profile  and  duration  of  nerve  sensory  block  and  the  potential  for  extended  post-operative  pain  management.
Additionally, we evaluated the safety and tolerability of LIQ865 in a rat toxicology study in 2016. The results of this study supported advancing LIQ865
into human clinical trials.

Phase 1 Trials

Our Phase 1a trial, completed in March 2017, was a randomized, double-blind, controlled, single ascending dose trial of two different PRINT formulations
of bupivacaine, LIQ865A and LIQ865B. The trial was conducted in 28 healthy male volunteers at a single site in Copenhagen, Denmark. LIQ865A consists
of particles combining bupivacaine and polylactic-glycolic acid, a polymer widely used in sustained-release drug products and surgical sutures. LIQ865B
consists  of  particles  of  bupivacaine  alone,  in  a  proprietary  diluting  agent.  The  study  design  included  dosing  multiple  cohorts,  or  groups,  each  receiving
increasing bupivacaine doses as either LIQ865A or LIQ865B: 150 mg, 225 mg, 300 mg, 450 mg or 600 mg. The LIQ865 formulation was injected into the
upper calf in one leg, and the other leg received the diluting agent without LIQ865 particles. The primary objective of this Phase 1a clinical trial was to
evaluate  the  safety  and  tolerability  profile  of  the  two  formulations  of  LIQ865.  We  also  assessed  bupivacaine  pharmacokinetic  and  pharmacodynamic
responses.

We observed a dose-response relationship in this trial, and all doses were well-tolerated. The results from this trial helped inform our selection of LIQ865A
for  further  investigation  in  the  United  States,  and  all  of  our  references  to  LIQ865  are  to  this  formulation.  All  adverse  events  were  mild  to  moderate  in
severity,  and  most  adverse  events  were  limited  locally  at  the  site  of  injection,  with  most  related  to  sensory  block  of  underlying  sensory  branches  of  the
saphenous nerve in the leg.

Mean  plasma  concentrations  of  bupivacaine  over  120  hours  comparing  the  150  mg,  225  mg,  300  mg,  450  mg  and  600  mg  dose  cohorts  of  LIQ865A
formulation, expressed on a logarithmic, or log, scale for the 16 volunteers who received LIQ865A are shown below:

LIQ865A Log Linear Mean Concentration Over Time

At  the  450  mg  dose  of  LIQ865,  all  subjects  had  maximum  concentration  values  below  800  ng/ml,  which  is  well  below  the  reported  thresholds  for
neurotoxicity  and  cardiac  toxicity  of  2,000  and  4,000  ng/mL,  respectively.  The  pharmacokinetic  and  pharmacodynamic  profile  for  this  dose  suggested  a
sustained duration of effect, with nearly all subjects receiving this dose reporting at least three days of sensory blunting in response to quantitative sensory
testing. LIQ865 also showed rapid onset of action at the one-hour time point in all subjects, even at the lowest dose of 150 mg. Additionally, we observed a
block of the distal sensory branches of the saphenous nerve below the knee in eight of nine subjects who received a 450 mg dose of LIQ865. This sensory
block lasted at least three days, which we believe further supports the duration profile of LIQ865.

In March 2017, we held a pre-IND meeting with the FDA and verified that the CMC and preclinical package were “phase-appropriate” and sufficient to
support our initial U.S. Phase 1 trial. Following our submission of the IND for LIQ865, we initiated our U.S. Phase 1b clinical trial in September 2017,
which was completed in April 2018. This trial used an experimental pain model in healthy male and female subjects with quantitative sensory testing after
an  injection  of  LIQ865  at  doses  of  150  mg,  300  mg  and  450  mg.  The  experimental  pain  model  was  designed  to  simulate  post-operative  pain  for  up  to
five days through a combination of localized ultraviolet B burn and mini-incision. Additionally, the trial included a cross-over design to compare LIQ865 to
EXPAREL.  We  observed  that  LIQ865  was  well-tolerated  across  the  range  of  doses.  All  adverse  events  were  mild  to  moderate,  and  no  dose-limiting
toxicities were noted. The pharmacokinetic profile was similar to that observed in the Phase 1a trial. Pharmacodynamic effects were highly variable and
inconclusive, which we associated with the experimental design of the pain model used in this Phase 1b trial.

Plans for Phase 2 Development

At our pre-IND meeting in March 2017, the FDA requested additional toxicology studies prior to the initiation of Phase 2 trials. Accordingly, we initiated
Phase 2-enabling toxicology studies in 2019 to assess LIQ865 in multiple non-clinical tissue models. Results from a study to assess incision tensile strength
after healing were acceptable and not statistically different from controls. A nonclinical study to examine soft tissue healing was also completed, and the
results were acceptable and comparable to vehicle-treated, saline-treated, and Marcaine-treated sites. We believe this data supports progression to Phase 2
hernia repair studies. In a study to assess bone fracture healing, we observed dose-dependent delayed healing at the two LIQ865 doses studied; however,
there  were  no  adverse  effects  noted  on  surrounding  soft  tissues.  Additional  studies  have  been  initiated  with  lower  doses  of  LIQ865  to  determine  a
NOAEL on bone healing. We will review the results from these toxicology studies, and if supportive, we intend to initiate  Phase 2 proof-of-concept clinical
trials,  subject  to  availability  of  capital  and  other  factors,  during  2021.  In  the  United  States,  we  plan  to  pursue  the  505(b)(2)  regulatory  pathway  for  our
development of LIQ865, which would allow us to rely on the FDA’s prior determinations of safety and efficacy for other products containing bupivacaine,
such as Marcaine and EXPAREL.

Competition

The  primary  competitor  for  LIQ865,  if  approved,  would  be  liposomal  bupivacaine,  marketed  as  EXPAREL  by  Pacira  Pharmaceuticals,  Inc.  Generic
equivalents of EXPAREL may also enter the market when EXPAREL loses patent protection, potentially as early as December 2021. While EXPAREL is
currently the only direct competitor to LIQ865 on the market, in October 2018 Heron Therapeutics, Inc., or Heron, announced the submission of its NDA to
the FDA for HTX-011, an investigational long-acting, extended-release formulation of the local anesthetic bupivacaine in a fixed-dose combination with the
anti-inflammatory meloxicam for the management of post-operative pain. HTX-011 was granted both breakthrough therapy and fast track designations, as
well as priority review, by the FDA. In May 2019, Heron announced that it received a complete response letter, or CRL, for HTX-011 from the FDA. In
October 2019, Heron announced that it had resubmitted its NDA for HTX-011 to the FDA and expected a six-month review period. In addition to Heron,
Durect Corporation and Innocoll Holdings plc each also have products in clinical development that are potential competitors to LIQ865. In addition to long-
acting local anesthetics, there are a number of indirect competitors in various stages of research and development, including opioids and other molecules
that target the treatment of pain through alternative pathways.

Our PRINT Technology

Both LIQ861 and LIQ865 are being developed using our proprietary PRINT particle engineering technology, which allows us to engineer and manufacture
highly  uniform  drug  particles  with  precise  control  over  the  size,  three-dimensional  geometric  shape  and  chemical  composition  of  the  particles.  By
controlling these physical and chemical parameters of particles, PRINT enables us to engineer desirable pharmacological benefits into product candidates,
including  prolonged  duration  of  drug  release,  increased  drug  loading,  more  convenient  routes  of  administration,  the  ability  to  create  novel  combination
products, enhanced storage and stability and the potential to reduce adverse side effects. Precisely controlling the physical and chemical characteristics of
drug particles enables us to research, identify and pursue the improvement of existing therapies and creation of new therapies from existing drugs or new
chemical entities, including small molecules and biologics.

Our  ability  to  design  and  control  these  features  of  drug  particles  has  the  potential  to  provide  significant  benefits  across  the  breadth  of  pharmaceutical
applications. Product characteristics and features can be tuned depending on the need of a particular application, drug substance, delivery route and other
such considerations. Based on our research to date, we anticipate the ability to:

● enhance inhaled delivery through the highly uniform geometric size, shape and composition of each drug particle;

24

 
 
 
 
 
 
 
 
 
 
 
● design desired drug release profiles ranging from minutes post-delivery to days, weeks, or months depending on the objective of a target therapy,

by controlling the chemical composition of the drug particles and the surface area-to-volume ratio of the particles;

● enable combination products where one or more of the chemical constituents can destabilize or interact by encapsulating the desired constituent in

a particle to shield it from another constituent during packaging and storage; and

● enhance the deposition and retention of topically delivered products by designing particles with a desired charge and/or Young’s modulus.

Our molding approach, which we branded as “PRINT” or Particle Replication In Non-wetting Templates,  combines  the  precision  of  the  semi-conductor
industry  with  the  high  throughput  of  roll-to-roll  manufacturing  to  make  highly  uniform  micro-  and  nano-particles  at  a  commercially  viable  scale.  Our
manufacturing equipment and materials used in the production of our drug particles are proprietary and protected by our patent portfolio and trade secret
know-how. Our PRINT equipment is also modular, scalable and cost-effective.

Our PRINT Process

We  begin  our  particle  design  by  procuring  a  custom  designed  master  template  etched  with  three-dimensional  structures,  or  posts,  that  will  become  the
eventual shape and size of our drug particles. These three-dimensional structures are then replicated in negative form, through our proprietary processing,
into flexible rolls of polymeric PRINT molds. Our PRINT molds consist of thousands of linear feet of thin flexible molds up to twenty-four inches wide. We
then  design  and  formulate  our  desired  drug  particle  composition  and  apply  that  to  our  PRINT  molds  in  our  high-throughput  roll-to-roll  processing
equipment,  with  each  particle  mimicking  the  shape  of  the  mold  cavity  from  which  it  was  molded,  thus  taking  the  shape  of  the  original  master  template
structures.

The general components and steps of our PRINT molding are as follows:

● Step A: Etch a master template with the three-dimensional geometric structures of the desired particle size and shape;

● Step B: Apply our proprietary polymeric mold material over the master template;

● Step C: Cure the polymeric material to form our PRINT molds with discrete molding cavities that replicate the structures of the master template;

● Step D: Design the chemical composition of the drug particle of interest;

● Step E: Apply the drug particle composition to the cavities in the mold to fill the cavities;

● Step F: Form the drug particles in the cavities of the mold that mimic the size and shape of the mold cavities;

● Step G: Remove the drug particles from the mold cavities on a harvesting film; and

● Step H:  Remove  the  particles  from  the  harvesting  film  for  further  functionalization,  purification  or  packaging  to  be  included  in  the  final  drug

particle product.

The diagram below shows the general steps involved in producing drug particles using our PRINT technology:

We have translated the PRINT process into a continuous, roll-to-roll manufacturing process that we believe is compliant with cGMP and scaled to support
clinical and commercial production, when required. One of our current manufacturing lines is shown below:

Manufacturing and Supply

Our  facilities  occupy  approximately  45,000  square  feet  and  are  located  in  Morrisville,  North  Carolina.  Within  these  premises,  there  are  office  space,
research and development laboratories and equipment, analytical development and quality control laboratories, research, development and mold production
facilities, research and development particle fabrication equipment, including three operational PRINT particle fabrication lines, all of which we believe are
cGMP-compliant, as well as appropriate staging, storage and stability facilities. These three operational PRINT particle fabrication lines are located within
class ISO7 clean rooms that operate under applicable ISO and cGMP air quality and environmental requirements.

We currently produce in this facility the product candidates for our preclinical studies and clinical trials. Our current operational PRINT particle fabrication
lines are scaled and capable of producing the necessary materials to support our ongoing operations and planned studies and clinical trials and, we believe,
ultimately our initial commercial scale manufacturing. The production capacity for each PRINT particle fabrication line within our production facility varies
depending on the drug particle that is being produced.

We depend on third-party suppliers for clinical supplies, including active pharmaceutical ingredients which are used in our product candidates. For example,
we currently rely on a sole supplier, LGM Pharma, LLC, or LGM Pharma, for treprostinil, the active pharmaceutical ingredient of LIQ861, and we currently
rely  on  a  sole  supplier,  Plastiape  S.p.A.,  or  Plastiape,  for  RS00  Model  8  DPI,  the  DPI  used  to  administer  LIQ861.  We  also  rely  on  a  sole  supplier,
Xcelience LLC (now a Lonza Group Ltd company), or Xcelience, for encapsulation and packaging services. If and when we receive marketing approval for
our product candidates, we may, from time to time, rely on third-party CMOs to produce, package and distribute some or all of our approved drug products
on a commercial scale.

Our Collaboration and Licensing Agreements

In  addition  to  advancing  our  own  product  candidates,  LIQ861  and  LIQ865,  we  have  collaborated,  and  may  consider  collaborating,  with  pharmaceutical
companies to develop their own product candidates across a wide range of therapeutic areas, molecule types and routes of administration, leveraging our
PRINT  technology.  These  collaborations  are  intended  to  help  advance  new  PRINT  capabilities  and  build  upon  our  competitive  advantage  in  the
pharmaceutical industry, while adding to our intellectual property portfolio.

We have exclusively licensed our PRINT technology to GSK for applications broadly across inhaled delivery of their small molecule and biologic chemical
entities,  although  we  retained  the  ability  to  develop  LIQ861.  As  discussed  below,  in  June  2019,  we  amended  our  Inhaled  Collaboration  and  Option
Agreement,  or  the  GSK  ICO  Agreement,  with  GSK,  to  secure  rights  to  develop  and  commercialize  three  additional  inhaled  therapeutics,  subject  to
milestone and royalty payments to GSK, and to establish a mechanism by which we may acquire rights to develop and commercialize further molecular
entities for inhaled applications.

We  have  also  exclusively  licensed  our  PRINT  technology  to  Aerie  Pharmaceuticals,  Inc.,  which  in  2017  acquired  most  of  the  assets  of  Envisia
Therapeutics, Inc., an entity which we formed in 2013, for broad usage in the design and commercialization of small molecule and biologic ophthalmic
therapies.

GlaxoSmithKline

Previously,  we  had  collaborated  with  GSK  on  the  use  of  our  PRINT  technology  in  respiratory  disease.  In  June  2012,  we  entered  into  the  GSK  ICO
Agreement with GSK to collaborate on research regarding the application of our PRINT technology to specified inhaled therapies. Pursuant to the GSK ICO
Agreement, we granted GSK exclusive options and licenses to further develop and commercialize such inhaled therapies using our PRINT technology. In
partial  consideration  of  the  rights  granted  to  GSK  under  the  GSK  ICO  Agreement,  we  received  a  one-time  up-front  payment  of  $4.0  million.  We  also
entered into a stock purchase agreement with GSK pursuant to which GSK purchased 4,765,248 shares of our Series C-1 convertible preferred stock for an
aggregate purchase price of $3.8 million.

27

 
 
 
 
 
 
 
 
 
 
 
 
In  September  2015,  GSK  exercised  its  option  to  obtain  an  exclusive,  worldwide  license  to  certain  of  our  know-how  and  patents  relating  to  our  PRINT
technology, for the purpose of, among others, preclinical studies of inhaled therapeutics developed, manufactured or otherwise produced using our PRINT
technology.  In  connection  with  the  grant  of  this  license,  we  received  a  one-time  option  exercise  fee  of  $15.0  million.  Under  the  terms  of  the  GSK  ICO
Agreement, we were also entitled to continued research and development funding and certain milestone payments aggregating up to $158 million upon the
achievement of specified events for new non-rescue therapeutic products. Rescue therapeutic products are therapeutics that GSK develops with our PRINT
technology that had previously been discontinued from development. We are also entitled to tiered royalties on the worldwide sales of the licensed products
at percentages ranging from the mid-single digits to low-single digits depending on the total number of products developed and other royalty step-down
events  with  a  fixed  low-single  digit  royalty  floor.  In  February  2016,  we  received  a  $3.0  million  payment  from  GSK  upon  the  achievement  of  a  clinical
development milestone related to the development of an inhaled antiviral for viral exacerbations in chronic obstructive pulmonary disease. However, in July
2018, GSK notified us of its plans to discontinue development of this compound after completion of the related Phase 1 clinical trial.

GSK has the right to terminate the GSK ICO Agreement in its entirety or on a product-by-product basis upon a specified period of prior written notice.
Upon termination of the GSK ICO Agreement, each party will continue to have the right to practice and/or license its interest in any know-how developed
during the collaboration without seeking the consent of, or accounting to, the other party.

In  June  2019,  we  and  GSK  executed  the  third  amendment  to  the  collaboration  agreement  providing  us  with  rights  to  develop  and  commercialize  three
specified  molecular  entities  for  application  in  inhaled  programs  using  our  PRINT  technology  at  our  sole  expense.  This  amendment  also  provides  a
mechanism for us to acquire rights to develop and commercialize further molecular entities for inhaled applications. New inhaled programs developed under
this amendment would carry milestone and royalty payments due to GSK upon initiation of Phase 3 studies and subsequent commercialization, respectively.
This amendment, among other factors, including the lack of continued performance anticipated by the Company and GSK under the original agreement, led
the Company to the belief that no further research and development services will be provided to GSK under the collaboration agreement. Accordingly, in
January 2020, we notified GSK of our intent to terminate the GSK ICO Agreement based upon GSK's lack of performance under the agreement, which we
believe constitutes a material breach of the agreement. In February 2020, we received a letter from GSK disputing our basis for termination.  The parties are
currently attempting to resolve the dispute pursuant to the terms of the GSK ICO Agreement.

The University of North Carolina at Chapel Hill

In December 2008, we entered into the Amended and Restated License Agreement with UNC for the use of certain patent rights and technology relating to
initial innovations of our PRINT technology, or the UNC License. Under the terms of the UNC License, we have an exclusive license to such patent rights
and technology for our drug products. The UNC License grants us the right to grant sublicenses to the technology as well as control the litigation of any
infringement claim instituted by or against us in respect of the licensed patent rights. We are also responsible for the costs of all expenses associated with the
prosecution and maintenance of the patents and patent applications. Such filings and prosecution will be carried out by UNC and in UNC’s name but under
our control.

Under  the  UNC  License,  we  are  required  to  pay  UNC  royalties  equal  to  a  low  single  digit  percentage  of  all  net  sales  of  our  drug  products  whose
manufacture, use or sale includes any use of the technology or patent rights covered by the UNC License, as well as tiered royalty percentages ranging in
the low single digits of sales by our sublicensees for any product covered by rights under a sublicense agreement granted pursuant to the UNC License.
Under  the  UNC  License,  we  are  also  required  to  pay  UNC  20%  of  all  fees  other  than  royalties  that  we  collect  and  are  attributable  to  UNC  sublicensed
intellectual  property.  As  consideration  for  the  UNC  License,  we  paid  UNC  a  license  issue  fee  in  the  form  of  196,469  shares  of  our  Class  B  non-voting
common  stock  in  2004.  During  the  term  of  the  UNC  License,  we  have  also  paid  approximately  $2.9  million  in  the  aggregate  to  UNC  pursuant  to  a
Supported Research Agreement, or the SRA. In connection therewith, we may exclusively license resulting inventions under the SRA for a $5,000 up-front
license  fee  per  invention.  We  have  also  paid  aggregate  consideration  of  $5.7  million  in  sublicense  fees  to  UNC  pursuant  to  the  UNC  License,  for  our
sublicenses  of  our  PRINT  technology  to  GSK  and  G&W  Laboratories,  Inc.,  a  former  licensee.  We  also  reimburse  UNC  for  its  costs  of  procuring  and
maintaining  the  patents  we  license  from  UNC.  Such  reimbursements  amounted  to  $142,531  for  the  year  ended  December  31,  2019.  Effective
November 2017, we satisfied all substantive milestones associated with our UNC License other than semi-annual and annual reporting-based milestones
that continue through the term of the UNC License. The UNC License expires (i) on the expiration of the last to expire patent included in the patent rights or
(ii) if no patents mature from such patent rights, in December 2028.

28

 
 
 
 
 
 
 
 
We  have  the  right  to  terminate  the  UNC  License  upon  a  specified  period  of  prior  written  notice.  UNC  may  terminate  the  UNC  License  in  certain
circumstances, including if we fail to pay royalty or other payments on time or if we fail to sublicense in accordance with the terms of the UNC License.
Upon termination of the UNC License, we must pay any royalty obligations due upon termination.

Intellectual Property

The proprietary nature and protection of our product candidates, their methods of use and our platform technology that enables our product candidates are
an important part of our business strategy of rapidly developing and commercializing new medicines that address areas of significant unmet medical needs.

Our  policy  is  to  seek  patent  protection  of  our  proprietary  product  candidates  and  technology  by  filing  U.S.,  international  and  certain  foreign  patent
applications  covering  certain  of  our  proprietary  technology,  inventions,  improvements  and  product  candidates  that  are  important  to  the  growth  and
protection  of  our  business.  We  also  rely  on  a  combination  of  trade  secrets,  know-how,  trademarks  and  contractual  restrictions  to  protect  aspects  of  our
business that are not amenable to patent protection or where we do not consider patent protection to be adequate or applicable.

Our success depends, in part, on our ability to obtain and maintain patent and other protection for our product candidates, enabling technology, inventions
and  know-how  and  our  ability  to  defend  and  enforce  these  patents,  preserve  the  proprietary  nature  of  our  trade  secrets  and  trademarks  and  operate  our
business  without  infringing  valid  and  enforceable  patent  and  other  proprietary  rights  of  third  parties.  We  pursue  both  composition-of-matter  patents  and
method-of-use  patents  for  our  product  candidates.  We  are  also  pursuing  patents  covering  our  proprietary  PRINT  micro-  and  nano-particle  fabrication
technology.

The term of individual patents depends upon the legal term for patents in the countries in which they are granted. In most countries, including the United
States, the patent term is generally 20 years from the earliest filing date of a non-provisional patent application to which the patent claims priority in the
applicable  country.  In  the  United  States,  a  patent’s  term  may,  in  certain  cases,  be  lengthened  by  patent  term  adjustment,  or  PTA,  which  compensates  a
patentee for administrative delays by the U.S. Patent and Trademark Office, or the USPTO, in examining and granting a patent, or may be shortened if a
patent is terminally disclaimed over a commonly owned patent or a patent naming a common inventor and having an earlier expiration date. The Patent
Term Restoration Act of 1984, as amended, or the Hatch-Waxman Act, permits a patent term extension, or PTE, of up to five years beyond the expiration
date of a U.S. patent as partial compensation for the length of time the drug is under regulatory review while the patent is in force. A PTE cannot extend the
remaining term of a patent beyond a total of 14 years from the date of product approval, and only one patent applicable to each regulatory review period
may be extended. Further, only those claims covering the approved drug, a method for using it or a method for manufacturing it may be extended and the
extension only applies to the approved drug, method for using it or method for manufacturing it for which the extension was obtained. Similar provisions
are available in Europe and certain other foreign jurisdictions to extend the term of a patent that covers an approved drug.

We  are  the  owner  or  exclusive  licensee  of  patents  and  applications  relating  to  our  proprietary  technology  platform  and  our  product  candidates,  and  are
pursuing additional patent protection for these and for our other product candidates and technology developments.

We have a total of 159 patents and pending patent applications in our patent portfolio. As of December 31, 2019, we were the sole owner of 14 patents in
the United States and 41 patents in foreign jurisdictions, as well as approximately 16 additional pending patent applications, including provisional patent
applications, in the United States, Europe, Japan and other jurisdictions. In addition to the patents and patent applications owned solely by us, our patent
portfolio also includes 72 patents and 16 patent applications licensed from third parties. As of December 31, 2019, we had an exclusive, worldwide license
from UNC to 18 U.S. patents and 53 foreign patents, as well as six additional patent applications in the United States or selected foreign jurisdictions. Five
of the patents and two of the patent applications in the portfolio licensed from UNC are jointly owned by us.

methods  of  using  such  compositions  for  inducing  extended  analgesia  and  methods  of  forming  such  compositions.  Any  patents  that  may  issue  from
PCT/US17/31397 are expected to expire on May 5, 2037, absent any patent term adjustments or extensions and assuming payment of all maintenance fees.

We hold multiple U.S. trademark registrations and have numerous pending trademark applications. Issuance of a federally registered trademark creates a
rebuttable presumption of ownership of the mark; however, it is subject to challenge by others claiming first use in the mark in some or all the areas in
which it is used. Federally registered trademarks have a perpetual life so long as they are maintained and renewed on a timely basis and used properly as
trademarks, subject to the rights of third parties to seek cancellation of the trademarks if they claim priority or confusion of usage. We believe our patents
and trademarks are valuable and would provide us certain benefits in marketing our products.

Sales and Marketing

We  hold  worldwide  commercialization  rights  to  LIQ861  and  LIQ865.  We  are  currently  exploring  opportunities  to  commercialize  LIQ861  in  the  United
States, subject to receiving regulatory approval, either by ourselves or through partnership or licensing arrangements with other pharmaceutical companies.
With respect to LIQ865, after reviewing the results of all of our Phase 2-enabling toxicology studies, and subject to the availability of sufficient funding, we
plan to evaluate whether to pursue continued internal development or to explore licensing arrangements with other pharmaceutical companies. Outside of
the  United  States,  we  intend  to  pursue  the  regulatory  approval  and  commercialization  of  LIQ861  and  LIQ865  through  licensing  arrangements  with
pharmaceutical companies with regional expertise. We have not yet established a substantial commercial organization or distribution capabilities.

If we decide to commercialize LIQ861, our lead product candidate, ourselves, we intend to focus our commercial efforts initially on the U.S. market, which
we believe represents the largest market opportunity. Within the United States, we believe that we can effectively commercialize LIQ861, if approved, with
an  initial  specialty  field  team  of  approximately  50  individuals.  We  intend  to  initially  pursue  a  highly  concentrated  target  market  of  PAH  centers  of
excellence and high prescribers of PAH therapies. Our physician call points within these sites of care will include cardiologists, pulmonologists and their
supporting staff. We expect to supplement our field team with medical science liaisons and reimbursement specialists to support the proper training and
utilization of LIQ861. As part of our commercialization strategy, we plan to educate physician specialists, healthcare practitioners, patients and caregivers of
the  benefits  of  LIQ861  and  its  proper  use.  We  plan  to  work  with  national  associations,  such  as  the  Pulmonary  Hypertension  Association,  and  patient
advocacy groups to update treatment guidelines to include LIQ861.

Competition

The pharmaceutical industry is intensely competitive, subject to rapid and significant technological change and places emphasis on the value of proprietary
products. While we believe that our technologies and experience provide us with a competitive advantage, our competitors include organizations such as
major multinational pharmaceutical companies, established biotechnology companies, biopharmaceutical companies and generic drug companies. Many of
our competitors have greater financial and other resources than we have, such as more commercial resources, larger research and development staffs and
more extensive marketing and manufacturing organizations. As a result, these companies may obtain marketing approval more rapidly than we are able and
may be more effective in selling and marketing their products. Smaller or early stage companies may also prove to be significant competitors, particularly
through collaboration arrangements with large, established companies.

Any product candidates that we successfully develop and commercialize will compete with existing therapies and new therapies that may become available
in  the  future.  Our  competitors  may  succeed  in  developing,  acquiring  or  licensing,  on  an  exclusive  basis,  technologies  and  drug  products  that  are  more
effective  or  less  costly  than  products  that  we  are  currently  developing  or  that  we  may  develop,  which  could  render  our  products  obsolete  and  non-
competitive.  We  expect  any  products  that  we  develop  and  commercialize  to  compete  on  the  basis  of,  among  others,  efficacy,  safety,  convenience  of
administration and delivery, price and the availability of reimbursement from government and other third-party payors. We also expect to face competition
in our efforts to recruit and retain qualified personnel, establish clinical trial sites and secure patient enrollment in our clinical trials, and identify appropriate
collaborators to help commercialize any approved products in our target commercial markets.

Employees

As  of  December  31,  2019,  we  had  64  total  employees,  all  of  which  are  full-time,  including  seven  employees  in  management  (including  our  executive
officers), 22 employees in research and development, 16 employees in manufacturing and technical operations, seven employees in regulatory and quality
and 12 employees in general and administration. All of our employees are employed in the United States.

Government Regulation

Government Regulation and Product Approval

Government authorities in the United States at the federal, state and local level and in other countries, extensively regulate, among other things, the research,
development, testing, manufacture, (including manufacturing changes), quality control, approval, labeling, packaging, storage, record-keeping, promotion,
advertising, distribution, marketing, export and import of products such as those we are developing. The processes for obtaining regulatory approvals in the
United States and in foreign countries, along with subsequent compliance with applicable statutes and regulations, require the expenditure of substantial
time and financial resources.

U.S. Drug Development Process

In the United States, the FDA regulates drugs under the United States Federal Food, Drug, and Cosmetic Act, or the FDCA, and the FDA’s implementing
regulations.

Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process or after approval may subject
an applicant to administrative or judicial sanctions. These sanctions could include the FDA’s refusal to approve pending applications, withdrawal of an
approval, a clinical hold, untitled or warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions,
fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties. The process required by the FDA before a drug may be
marketed in the United States generally involves the following:

● completion of preclinical laboratory tests, animal studies and formulation studies according to Good Laboratory Practices regulations;

● submission to the FDA of an Investigational New Drug application, or IND, which must become effective before human clinical studies may

begin;

● approval by an independent IRB at each clinical site before each trial may be initiated;

● performance of adequate and well-controlled human clinical studies according to Good Clinical Practice, or GCP, regulations, to establish the

safety and efficacy of the proposed drug for its intended use;

● preparation and submission to the FDA of an NDA, containing the results of product development, preclinical studies and clinical trials, along with
descriptions of the manufacturing process, analytical tests conducted on the drug product, proposed labeling and other relevant information, to
request approval to market the drug product;

33

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the drug product, or components thereof, are

produced to assess compliance with cGMP to assure that the facilities, methods and controls are adequate to preserve the drug’s identity, strength,
quality and purity;

● satisfactory completion of FDA audits of clinical trial sites to assure compliance with GCPs and the integrity of clinical data;

● FDA review and approval of the NDA;

● payment of fees, including annual program fees for each drug product on the market; and

● ongoing compliance with any post approval requirements, including risk evaluation and mitigation strategy, or REMS, and post approval studies

required by the FDA.

The testing and approval process requires substantial time, effort and financial resources, and we cannot be certain that any approvals for our product
candidates will be granted on a timely basis, if at all.

Once a pharmaceutical product candidate is identified for development, it enters the preclinical testing stage. Preclinical tests include laboratory evaluations
of product chemistry, toxicity, formulation and stability, as well as animal studies. When a sponsor wants to proceed to test the product candidate in humans,
it must submit an IND in order to conduct clinical trials.

An IND sponsor must submit the results of the preclinical tests, together with manufacturing information, analytical data and any available clinical data or
literature, to the FDA as part of the IND. The sponsor must also include a protocol detailing, among other things, the objectives of the initial clinical study,
the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated if the initial clinical study lends itself to an efficacy evaluation.
Some preclinical testing may continue even after the IND is submitted. The IND automatically becomes effective 30 days after receipt by the FDA, unless
the FDA raises concerns or questions related to a proposed clinical study and places the study on a clinical hold within that 30-day time period. In such a
case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical study can begin. Clinical holds also may be imposed by the
FDA at any time before or during clinical studies due to safety concerns or non-compliance, and may be imposed on all product candidates within a certain
pharmaceutical class. The FDA also can impose partial clinical holds, for example, prohibiting the initiation of clinical studies of a certain duration or for a
certain dose.

All clinical studies must be conducted under the supervision of one or more qualified investigators in accordance with GCP regulations. These regulations
include the requirement that all research subjects provide informed consent in writing before their participation in any clinical study. Further, an IRB must
review and approve the plan for any clinical study before it commences at any institution, and the IRB must conduct continuing review and reapprove the
study at least annually. An IRB considers, among other things, whether the risks to individuals participating in the clinical study are minimized and are
reasonable in relation to anticipated benefits. The IRB also approves the information regarding the clinical study and the consent form that must be provided
to each clinical study subject or his or her legal representative and must monitor the clinical study until completed.

Each new clinical protocol and any amendments to the protocol must be submitted for FDA review, and to the IRBs for approval. Protocols detail, among
other things, the objectives of the clinical study, dosing procedures, subject selection and exclusion criteria and the parameters to be used to monitor subject
safety.

Information about certain clinical trials must be submitted within specific timeframes to the National Institutes of Health, or NIH, for public dissemination
on their ClinicalTrials.gov website.

34

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Human clinical studies are typically conducted in three sequential phases that may overlap or be combined:

● Phase 1. The product is initially introduced into a small number of healthy human subjects or patients and tested for safety, dosage tolerance,

absorption, metabolism, distribution and excretion and, if possible, to gain early evidence on effectiveness. In the case of some products for severe
or life-threatening diseases, especially when the product is suspected or known to be unavoidably toxic, the initial human testing may be conducted
in patients.

● Phase 2. Involves clinical studies in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the

efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage and schedule.

● Phase 3. Clinical studies are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population at geographically
dispersed clinical study sites. These clinical studies are intended to establish the overall risk/benefit relationship of the product and provide an
adequate basis for product labeling.

Progress reports detailing the results of the clinical studies must be submitted at least annually to the FDA and safety reports must be submitted to the FDA
and the investigators for serious and unexpected suspected adverse events. Phase 1, Phase 2 and Phase 3 testing may not be completed successfully within
any specified period, if at all. The FDA or the sponsor may suspend or terminate a clinical study at any time on various grounds, including a finding that the
research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical study at its
institution if the clinical study is not being conducted in accordance with the IRB’s requirements or if the drug has been associated with unexpected serious
harm to patients.

There are FDA-imposed limitations on communications about investigational drugs. The FDA prohibits companies from making promotional claims of
safety or effectiveness of the drug for a use for which it is under investigation, and from “commercialization” of the drug before it is approved for
commercial distribution.

Concurrent with clinical studies, companies usually complete additional animal studies and must also develop additional information about the chemistry
and physical characteristics of the product and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP
requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, the
manufacturer must develop methods for testing the identity, strength, quality and purity of the final product. Additionally, appropriate packaging must be
selected and tested, and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its
shelf life.

U.S. Review and Approval Processes

Assuming successful completion of the required clinical testing, the results of product development, preclinical studies and clinical studies, along with
descriptions of the manufacturing process, analytical tests conducted on the drug, proposed labeling and other relevant information, are submitted to the
FDA as part of an NDA for a new drug, requesting approval to market the product.

The submission of an NDA is subject to the payment of a substantial application user fee although a waiver of such fee may be obtained under certain
limited circumstances. For example, the agency will waive the application fee for the first human drug application that a small business or its affiliate
submits for review. The sponsor of an approved NDA is also subject to annual program user fees.

In addition, under the Pediatric Research Equity Act of 2003, or PREA, an NDA application (or a supplement to an application) for a new active ingredient,
new indication, new dosage form, new dosing regimen or new route of administration must contain a Pediatric Assessment. If so, the submission must
contain data from pediatric studies that are adequate to assess the safety and effectiveness of the drug for the claimed indications in all relevant pediatric
subpopulations, and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective, unless the applicant
has obtained a waiver or deferral. PREA applies only to products developed for diseases that occur in both adult and pediatric populations, and generally
does not apply to products with Orphan Drug Designation or to ANDAs for generic drugs.

35

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
A sponsor who is planning to submit a marketing application for a drug product that is subject to the PREA requirements must submit an initial Pediatric
Study Plan, or PSP. The FDA encourages all applications to submit the PSP as soon as possible in the drug development process, and to discuss the plan
with FDA at critical points in the development process. For products intended for life-threatening or severely debilitating illnesses, applicants are
encouraged to discuss the PSP at the Pre-IND meeting and End-of-Phase 1 meeting. For products not intended for such illnesses, the FDA recommends that
sponsors submit and discuss the PSP no later than the End-of-Phase 2, or EOP2, meeting. The initial PSP must include an outline of the pediatric study or
studies that the sponsor plans to conduct, including study objectives and design, age groups, relevant endpoints and statistical approach, or a justification for
not including such detailed information. The FDA and the sponsor must reach agreement on the PSP. A sponsor can submit amendments to an agreed-upon
initial PSP at any time if changes to the pediatric plan need to be considered based on data collected from preclinical studies, early phase clinical studies or
other clinical development programs. The sponsor may submit a request for a deferral of pediatric assessments or a full or partial waiver of the requirement
to provide data from pediatric studies along with supporting information. The FDA may, on its own initiative or at the request of the applicant, grant
deferrals for submission of data or full or partial waivers. The FDA may, on its own initiative or at the request of the applicant, grant deferrals for
submission of data or full or partial waivers. It is critical that sponsors are in compliance with the PREA, as non-compliance may result in the FDA
considering the drug product misbranded solely on that basis.

The FDA also may require submission of a REMS to mitigate any identified or suspected serious risks. The REMS could include medication guides,
physician communication plans, assessment plans and elements to assure safe use, such as restricted distribution methods, patient registries or other risk
minimization tools.

The FDA reviews all NDAs submitted to ensure that they are sufficiently complete for substantive review before it accepts them for filing. The FDA may
request additional information rather than accept an application for filing. In this event, the application must be re-submitted with the additional information.
The re-submitted application also is subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-
depth substantive review.

The FDA reviews an NDA to determine whether a product is safe and effective for its intended use, which includes assessment of preclinical and clinical
data; proposed labeling; CMC data; and an assessment of whether the manufacturing processes and facilities meet the appropriate requirements and comply
with the applicable regulations (including cGMP requirements and adequate assurance for consistent commercial production of the product within required
specifications). There are numerous FDA personnel assigned to review different aspects of an NDA, exercising judgment, discretion, and interpretation of
data relative to the review process.

The FDA may approve an NDA only if, among other things, the methods used in, and the facilities and controls used for, the manufacture processing,
packing and testing of the product are adequate to ensure and preserve its identity, strength, quality and purity.

Before approving an NDA, the FDA often will inspect the facility or facilities where the product is or will be manufactured.

The FDA may refer the NDA to an advisory committee for review, evaluation and recommendation as to whether the application should be approved and
under what conditions. An advisory committee is a panel of experts, including clinicians and other scientific experts, who provide advice and
recommendations when requested by the FDA. The FDA is not bound by the recommendation of an advisory committee, but it considers such
recommendations when making decisions.

Additionally, before approving an NDA, the FDA will typically inspect one or more clinical sites to assure clinical data supporting the submission were
developed in compliance with GCP.

36

 
 
 
 
 
 
 
 
 
 
The approval process is lengthy and difficult, and the FDA may refuse to approve an NDA if the applicable regulatory criteria are not satisfied, or may
require additional preclinical, clinical or CMC data or other data and information. Even if such data and information are submitted, the FDA may ultimately
decide that the NDA does not satisfy the criteria for approval. Data obtained from clinical studies, as well as other types of supporting data, are not always
conclusive and the FDA may interpret data differently than an applicant interprets the same data.

After the FDA’s evaluation of an application, the FDA may issue an approval letter or a complete response letter to indicate that the review cycle is
complete and that the application is not ready for approval. A complete response letter generally contains a statement of specific conditions that must be met
to secure final approval of the application and may require additional clinical or preclinical testing for the FDA to reconsider the application. The
deficiencies identified may be minor, for example, requiring labeling changes, or major, for example, requiring additional clinical studies. Additionally, the
complete response letter may include recommended actions that the applicant might take to place the application in a condition for approval. If a complete
response letter is issued, the applicant may either resubmit the application, addressing all of the deficiencies identified in the letter, or withdraw the
application, or request an opportunity for a hearing.

Even with submission of additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval. If
and when those conditions have been met to the FDA’s satisfaction, the FDA will typically issue an approval letter. An approval letter authorizes
commercial marketing of the drug with specific prescribing information for specific indications.

If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise
be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings or precautions
be included in the product labeling. In addition, the FDA may require post-approval studies, including Phase 4 clinical studies, to further assess safety and
effectiveness after approval and may require testing and surveillance programs to monitor the safety of approved products that have been commercialized.
After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are
subject to further testing requirements and FDA review and approval.

New Drug Applications

Most drug products obtain FDA marketing approval pursuant to an NDA (described above) for innovator products, or an abbreviated new drug application,
or ANDA, for generic products. Relevant to ANDAs, the Hatch-Waxman Act amendments to the FDCA established a statutory procedure for submission
and FDA review and approval of ANDAs for generic versions of branded drugs previously approved by the FDA (such previously approved drugs are also
referred to as listed drugs). Because the safety and efficacy of listed drugs have already been established by the brand company (sometimes referred to as
the innovator), the FDA does not require new human clinical trials to establish safety and efficacy of generic products. Rather, a generic manufacturer is
typically required to conduct bioequivalence studies of its test product against the listed drug. The bioequivalence studies for orally administered,
systemically available drug products assess the rate and extent to which the active pharmaceutical ingredient is absorbed into the bloodstream from the drug
product and becomes available at the site of action. Bioequivalence is established when there is an absence of a significant difference in the rate and extent
for absorption of the generic product and the listed drug. For some drugs, including locally acting drugs such as topical anti-fungals, other means of
demonstrating bioequivalence may be required by the FDA, especially where rate and/or extent of absorption are difficult or impossible to measure. In
addition to the bioequivalence data, an ANDA must contain patent certifications and chemistry, manufacturing, labeling and stability data.

A third alternative is a special type of NDA, commonly referred to as a 505(b)(2) NDA, which enables the applicant to rely, in part, on the FDA’s findings
of safety and efficacy of an existing product, or published literature, in support of its application. 505(b)(2) NDAs often provide an alternate path to FDA
approval for new or improved formulations or new uses of previously approved products. Section 505(b)(2) permits the filing 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. The applicant may rely upon the FDA’s findings with respect to certain preclinical or clinical studies conducted for an approved product. The
FDA may also require companies to perform additional studies or measurements to support the change from the approved product. The FDA may then
approve the new product candidate for all or some of the label indications for which the referenced product has been approved, as well as for any new
indication sought by the 505(b)(2) applicant.

37

 
 
 
 
 
 
 
 
 
In seeking approval for a drug through an NDA, including a 505(b)(2) NDA, applicants are required to list with the FDA certain patents of the applicant or
that are held by third parties whose claims cover the applicant’s product. Upon approval of an NDA, each of the patents listed in the application for the drug
is then published in the Orange Book. Any subsequent applicant who files an ANDA seeking approval of a generic equivalent version of a drug listed in the
Orange Book or a 505(b)(2) NDA referencing a drug listed in the Orange Book must make one of the following certifications to the FDA concerning
patents: (1) the patent information concerning the reference listed drug product has not been submitted to the FDA; (2) any such patent that was filed has
expired; (3) the date on which such patent will expire; or (4) such patent is invalid, unenforceable or will not be infringed upon by the manufacture, use or
sale of the drug product for which the application is submitted. This last certification is known as a paragraph IV certification. A notice of the paragraph IV
certification must be provided to each owner of the patent that is the subject of the certification and to the holder of the approved NDA to which the ANDA
or 505(b)(2) application refers. The applicant may also elect to submit a “section viii” statement certifying that its proposed label does not contain (or carves
out) any language regarding the patented method-of-use rather than certify to a listed method-of-use patent.

If the reference NDA holder or patent owners assert a patent challenge directed to one of the Orange Book listed patents within 45 days of the receipt of the
paragraph IV certification notice, the FDA is prohibited from approving the application until the earlier of 30 months from the receipt of the paragraph IV
certification expiration of the patent, settlement of the lawsuit or a decision in the infringement case that is favorable to the applicant. The ANDA or 505(b)
(2) application also will not be approved until any applicable non-patent exclusivity listed in the Orange Book for the branded reference drug has expired as
described in further detail below. Thus approval of a 505(b)(2) NDA or ANDA can be prevented until all the listed patents claiming the referenced product
have expired, until any non-patent exclusivity, such as exclusivity for obtaining approval of a new chemical entity, listed in the Orange Book for the
referenced product has expired, and, in the case of a Paragraph IV certification and subsequent patent infringement suit, until the earlier of 30 months,
settlement of the lawsuit or a decision in the infringement case that is favorable to the ANDA or 505(b)(2) applicant.

Combination Products

Medical products containing a combination of new drugs, biological products, or medical devices are regulated as “combination products” in the United
States. A combination product generally is defined as a product comprised of components from two or more regulatory categories, such as drug/device,
device/biologic or drug/biologic. The term combination product includes: (i) a product comprised of two or more regulated components (i.e., drug/device,
biologic/device, drug/biologic or drug/device/biologic, that are physically, chemically or otherwise combined or mixed and produced as a single entity);
(ii) two or more separate products packaged together in a single package or as a unit and comprised of drug and device products, device and biological
products or biological and drug products; (iii) a drug, device or biological product packaged separately that according to its investigational plan or proposed
labeling is intended for use only with an approved individually specified drug, device or biological product where both are required to achieve the intended
use, indication or effect and where upon approval of the proposed product the labeling of the approved product would need to be changed, such as to reflect
a change in intended use, dosage form, strength, route of administration, or significant change in dose; or (iv) any investigational drug, device or biological
product packaged separately that according to its proposed labeling is for use only with another individually specified investigational drug, device, or
biological product where both are required to achieve the intended use, indication or effect.

Each constituent part of a combination product is subject to the requirements established by the FDA for that type of constituent part, whether a new drug,
biologic or device. In order to facilitate pre-market review of combination products, the FDA designates one of its centers to have primary jurisdiction for
the pre-market review and regulation of the overall product based upon a determination by FDA of the primary mode of action of the combination product,
and typically one application, such as for a drug/device combination product assigned to the FDA’s Center for Drug Evaluation and Research, or CDER, an
NDA, will be made.

38

 
 
 
 
 
 
 
A device with the primary purpose of delivering or aiding in the delivery of a drug and distributed containing a drug (i.e., a “prefilled delivery system”) is
typically evaluated by CDER using drug authorities and device authorities, as necessary.

A device with the primary purpose of delivering or aiding in the delivery of a drug and that is distributed without the drug (i.e., unfilled) is typically
evaluated by the FDA’s Center for Devices and Radiological Health and CDER, respectively, unless the intended use of the two products, through labeling,
creates a combination product.

The FDA has indicated that dry powder inhalers, such as our lead product candidate, LIQ861, are drug/device combination products.

Post-Approval Requirements

Drugs  manufactured  or  distributed  pursuant  to  FDA  approvals  are  subject  to  extensive  and  continuing  regulation  by  the  FDA,  including,  among  other
things,  requirements  relating  to  recordkeeping  (including  certain  electronic  record  and  signature  requirements),  periodic  reporting,  drug  supply  chain
security surveillance and tracking requirements, product sampling and distribution, advertising and promotion and reporting of certain adverse experiences,
deviations and other problems with the product. After approval, most changes to the approved product, such as adding new indications or other labeling
claims are subject to prior FDA review and approval. There are also, under The Prescription Drug User Fee Act, continuing, annual FDA “program fee”
requirements for products once they are approved, as well as new application fees for supplemental applications with clinical data.

The FDA strictly regulates labeling, advertising, promotion and other types of information on products that are placed on the market. Products may be
promoted only for the approved indications and in accordance with the provisions of the approved label. Further, manufacturers must continue to comply
with cGMP requirements, which are extensive and require considerable time, resources and ongoing investment to ensure compliance. In addition, changes
to the manufacturing process generally require prior FDA approval before being implemented and other types of changes to the approved product, such as
adding new indications and additional labeling claims, are also subject to further FDA review and approval.

Manufacturers and certain other entities involved in the manufacturing and distribution of approved products are required to register their establishments
with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with
cGMP and other laws. The cGMP requirements apply to all stages of the manufacturing process, including the production, processing, sterilization,
packaging, labeling, storage and shipment of the product. Manufacturers must establish validated systems to ensure that products meet specifications and
regulatory standards, and test each product batch or lot prior to its release. Combination products are subject to FDA regulation to ensure the quality of both
the constituent parts and the finished product.

Changes to the manufacturing process are strictly regulated and often require prior FDA approval before being implemented. FDA regulations also require
investigation and correction of any deviations from cGMP and impose reporting and documentation requirements upon the sponsor and any third-party
manufacturers that the sponsor may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and
quality control to maintain cGMP compliance.

The FDA may impose a number of post-approval requirements as a condition of approval of an application. For example, the FDA may require post-
marketing testing, including Phase 4 clinical trials, and surveillance to further assess and monitor the product’s safety and effectiveness after
commercialization.

The FDA may withdraw a product approval if compliance with regulatory requirements is not maintained or if problems occur after the product reaches the
market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, problems with
manufacturing processes, or failure to comply with regulatory requirements, may result in restrictions on the product or even complete withdrawal of the
product from the market.

Potential implications include required revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical trials
to assess new safety risks; or imposition of distribution or other restrictions under a REMS program. Other potential consequences include, among other
things:

● restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;

● warning letters or holds on post-approval clinical trials;

● refusal of the FDA to approve pending NDAs or supplements to approved NDAs, or suspension or revocation of product license approvals;

● product seizure or detention, or refusal to permit the import or export of products; or

● injunctions or the imposition of civil or criminal penalties.

The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Drugs may be promoted only for the
approved indications and in accordance with the provisions of the approved label. As a compliance best practice and risk mitigation measure,
pharmaceutical companies typically train their sales force regarding the limitations on promotion of products relative to their approved indications for use
and concerns regarding potential “off-label promotion.” However, a physician may use products off-label, when in the physician’s independent professional
medical judgment he or she deems it appropriate. Recent court decisions have impacted FDA’s enforcement activity regarding off-label promotion in the
light of First Amendment considerations; however, there are still significant risks in this area in part due to the potential for False Claims Act exposure.
Further, the FDA as not materially changed its position on off-label promotion following legal setbacks on First Amendment grounds and the U.S.
Department of Justice has consistently asserted in False Claims Act briefings that “speech serves as a conduit for violations of the law is not constitutionally
protected.”

The distribution of prescription drugs is subject to the Drug Supply Chain Security Act, or DSCSA, which regulates the distribution of the products at the
federal level, and sets certain standards for federal or state registration and compliance of entities in the supply chain and regulation of manufacturers and
repackagers, wholesale distributors, third-party logistics providers, and dispensers. The DSCSA preempts certain previously enacted state pedigree laws and
upon taking effect superseded the pedigree requirements of the Prescription Drug Marketing Act, or PDMA. Trading partners within the drug supply chain
must now ensure certain product tracing requirements are met, and are required to exchange transaction information, transaction history, and transaction
statements. Further, the DSCSA limits the distribution of prescription pharmaceutical products and imposes requirements to ensure overall accountability
and security in the drug supply chain. Product identifier information (an aspect of the product tracing scheme) is also now required. The DSCSA
requirements, development of standards, and the system of product tracing have been and will continue to be phased in over a period of years through 2023,
and subject companies will need to continue their implementation efforts. Many states still have in place licensure and other requirements for manufacturers
and distributors of drug products. The distribution of product samples continues to be regulated under the PDMA, and some states also impose regulations
on drug sample distribution.

From time to time, legislation is drafted, introduced and passed in Congress that could significantly change the statutory provisions governing the approval,
manufacturing and marketing of products regulated by the FDA. In addition to new legislation, FDA regulations, guidance and policies are often revised or
reinterpreted by the agency in ways that may significantly affect our business and our product candidates. It is impossible to predict whether further
legislative or FDA regulation or policy changes will be enacted or implemented and what the impact of such changes, if any, may be.

Patent Term Restoration

Depending upon the timing, duration and specifics of FDA approval of the use of our product candidates, some of our U.S. patents may be eligible for
limited PTE under the Hatch-Waxman Act. The Hatch-Waxman Act permits a patent restoration term of up to five years as compensation for patent term
effectively lost during product development and the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a
patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-half the time between the effective
date of an IND and the submission date of an NDA plus the time between the submission date of an NDA and the approval of that application, except that
the review period is reduced by any time during which the applicant failed to exercise due diligence. Only one patent applicable to an approved drug is
eligible for the extension. Extensions are not granted as a matter of right and the extension must be applied for prior to expiration of the patent and within a
sixty day period from the date the product is first approved for commercial marketing. The USPTO, in consultation with the FDA, reviews and approves the
application for any PTE or restoration. In the future, we may apply for PTEs, defined as the length of the regulatory review of products covered by our
granted patents, for some of our currently owned or licensed applications and patents to add patent life beyond their current expiration dates. Such
extensions will depend on the length of the regulatory review; however, there can be no assurance that any such extension will be granted to us.

Marketing Exclusivity

Market exclusivity provisions under the FDCA can also delay the submission or the approval of certain applications. The specific scope varies, but
fundamentally the FDCA provides a five-year period of non-patent marketing exclusivity within the United States to the first applicant to gain approval of
an NDA for a new chemical entity. A drug is a new chemical entity if the FDA has not previously approved any other new drug containing the same active
moiety, which is the molecule or ion responsible for the action of the drug substance. During the exclusivity period, the FDA may not accept for review an
ANDA or a 505(b)(2) NDA submitted by another company for another version of such drug where the applicant does not own or have a legal right of
reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of patent invalidity or
non-infringement. The FDCA also provides three years of marketing exclusivity for an NDA, 505(b)(2) NDA or supplement to an existing NDA if new
clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the
approval of the application, for example, for new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the conditions
of use associated with the new clinical investigations and does not prohibit the FDA from approving applications for drugs containing the original active
agent. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be
required to conduct or obtain a right of reference to all of the preclinical studies and adequate and well-controlled clinical studies necessary to demonstrate
safety and effectiveness.

Pediatric exclusivity is another type of exclusivity in the United States. Pediatric exclusivity, if granted, provides an additional six months to the term of any
existing regulatory exclusivity, including the non-patent exclusivity periods described above. This six-month exclusivity may be granted based on the
voluntary completion of a pediatric clinical study that “fairly responds” to an FDA-issued “Written Request” for such a clinical study.

Pharmaceutical Coverage, Pricing and Reimbursement

In the United States, sales of any products for which we may receive regulatory approval for commercial sale will depend in part on the availability of
coverage and reimbursement from third-party payors. Third-party payors include government authorities, managed care providers, private health insurers
and other organizations.

Significant uncertainty exists as to the coverage and reimbursement status of any products for which we may obtain regulatory approval. Some of the
additional requirements and restrictions on coverage and reimbursement levels imposed by third-party payors influence the purchase of healthcare services
and products. The process for determining whether a third-party payor will provide coverage for a product may be separate from the process for establishing
the reimbursement rate that such a payor will pay for the product. Third-party payors may limit coverage to specific drugs on an approved list, or formulary,
which might not include all of the FDA-approved drugs for a particular indication, or place drugs at certain formulary levels that result in lower
reimbursement levels. Moreover, a payor’s decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be
approved. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our
investment in product development. Further, one payor’s determination to provide coverage does not assure that other payors will also provide coverage and
reimbursement for the product, and the level of coverage and reimbursement may differ significantly from payor to payor as there is no uniform policy of
coverage and reimbursement for drug products among third-party payors.

41

 
 
 
 
 
 
 
 
 
 
Reimbursement may also impact the demand for drug products that obtain marketing approval. If coverage for a drug product is obtained by a third-party
payor, the resulting reimbursement payment rates may not be adequate or may require co-payments that patients find unacceptably high. Further, third party
payors require onerous prior approvals or implement other forms of restricted access that make it difficult for patients to utilize our drug products. Patients
who are prescribed medications for the treatment of their conditions, and their prescribing physicians, generally rely on third-party payors to reimburse all
or part of the costs associated with their prescription drugs. Prescribing physicians are unlikely to use or prescribe drug products unless coverage is provided
and reimbursement is adequate to cover all or a significant portion of the cost of those drug products. If reimbursement is not available, or is available only
to limited levels, a drug product which has obtained marketing approval may not be successfully commercialized.

Third-party payors are increasingly challenging the price and examining the medical necessity and cost-effectiveness of medical products and services, in
addition to their safety and efficacy. In order to obtain and maintain coverage and reimbursement for any product that might be approved for sale, we may
need to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of any products, in addition to
the costs required to obtain regulatory approvals. Our product candidates may not be considered medically necessary or cost-effective. If third-party payors
do not consider a product to be cost-effective compared to other available therapies, they may not cover the product after approval as a benefit under their
plans or, if they do, the level of payment may not be sufficient to allow a company to sell its products at a profit.

The U.S. government and state legislatures have shown significant interest in implementing cost containment programs to limit the growth of government-
paid healthcare costs, including price controls, restrictions on reimbursement and coverage and requirements for substitution of generic products for branded
prescription drugs. There has been increasing legislative and enforcement interest in the United States with respect to drug pricing practices. For example,
U.S. federal prosecutors have issued subpoenas to pharmaceutical companies seeking information about pricing practices in connection with an
investigation into pricing practices being conducted by the DOJ. Several state attorneys general also have commenced drug pricing investigations and filed
lawsuits against pharmaceutical companies, and the U.S. Senate has publicly investigated a number of pharmaceutical companies relating to price increases
and pricing practices. Proposed legislation has been designed to, among other things, bring more transparency to drug pricing, reduce the cost of
prescription drugs under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government program
reimbursement methodologies for drugs. Recent federal budget proposals have included measures to permit Medicare Part D plans to negotiate the price of
certain drugs under Medicare Part B, to allow some states to negotiate drug prices under Medicaid, and to eliminate cost sharing for generic drugs for low-
income patients. The U.S. Congress and the Trump Administration have indicated that they will continue to seek new legislative and administrative
measures to control drug costs, including by addressing the role of pharmacy benefit managers, or PBMs, in the supply chain. Drug pricing is and will
remain a key bipartisan issue in the coming year. If drug pricing reform is not meaningfully addressed before the 2020 election, policies to be pursued in the
future may be more aggressive, regardless of which party controls the White House. At the state level, legislatures have increasingly passed legislation and
implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts,
restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from
other countries and bulk purchasing. Adoption of government controls and measures, and tightening of restrictive policies in jurisdictions with existing
controls and measures, could exclude or limit our drugs and product candidates from coverage and limit payments for pharmaceuticals. We anticipate that
current and future U.S. federal and state legislative proposals may result in additional downward pressure on drug pricing and reimbursement, which could
have a significant impact on our business.

In addition, we expect that the increased emphasis on managed care and cost containment measures in the United States by third-party payors and
government authorities to continue and will place pressure on pharmaceutical pricing and coverage. Coverage policies and third-party reimbursement rates
may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for which we receive regulatory
approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

Other Healthcare Laws and Compliance Requirements

Healthcare providers, physicians and third-party payors often play a primary role in the recommendation and prescription of any currently marketed
products and product candidates for which we may obtain marketing approval. Our current and future arrangements with healthcare providers, physicians,
third-party payors and customers, and our sales, marketing and educational activities, may expose us to broadly applicable fraud and abuse and other
healthcare laws and regulations (at the federal and state level) that may constrain our business or financial arrangements and relationships through which we
market, sell and distribute our products for which we obtain marketing approval.

In addition, we may be subject to transparency laws and patient privacy regulation by both the federal government and the states in which we conduct our
business. The laws that may affect our ability to operate include the following:

● The federal Anti-Kickback Statute, which prohibits, among other things, persons and entities including pharmaceutical manufacturers from

knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, overtly or covertly, in cash or in kind, to
induce or reward, or in return for, either the referral of an individual for, or the purchase, lease, order or recommendation of, an item or service
reimbursable, in whole or in part, under a federal healthcare program, such as the Medicare and Medicaid programs. This statute has been
interpreted broadly to apply to, among other things, arrangements between pharmaceutical manufacturers on the one hand and prescribers,
purchasers and formulary managers on the other hand. The term “remuneration” expressly includes kickbacks, bribes or rebates and also has been
broadly interpreted to include anything of value, including, for example, gifts, discounts, waivers of payment, ownership interest and providing
anything at less than its fair market value. There are a number of statutory exceptions and regulatory safe harbors protecting certain common
activities from prosecution or other regulatory sanctions, however, the exceptions and safe harbors are drawn narrowly, and practices that do not fit
squarely within an exception or safe harbor may be subject to scrutiny. The failure to meet all of the requirements of a particular applicable
statutory exception or regulatory safe harbor does not make the conduct per se illegal under the federal Anti-Kickback Statute. Instead, the legality
of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all of its facts and circumstances. Our practices may
not meet all of the criteria for safe harbor protection from federal Anti-Kickback Statute liability in all cases. A person or entity does not need to
have actual knowledge of the federal Anti-Kickback Statute or specific intent to violate it to have committed a violation. In addition, the
Affordable Care Act codified case law that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute
constitutes a per se false or fraudulent claim for purposes of the federal civil False Claims Act.

● The federal civil and criminal false claims laws and civil monetary penalty laws, including the civil False Claims Act, which prohibits individuals

or entities from, among other things, knowingly presenting, or causing to be presented, claims for payment to, or approval by, the federal
government that are false, fictitious or fraudulent or knowingly making, using or causing to be made or used, a false record or statement material to
a false or fraudulent claim to avoid, decrease or conceal an obligation to pay money to the federal government. As a result of a modification made
by the Fraud Enforcement and Recovery Act of 2009, a claim includes “any request or demand” for money or property presented to the federal
government. Although we do not submit claims directly to payors, manufacturers can be held liable under these laws if they are deemed to “cause”
the submission of false or fraudulent claims by, for example, providing inaccurate billing or coding information to customers, promoting a product
off-label, marketing products of sub-standard quality, or, as noted above, paying a kickback that results in a claim for items or services. In addition,
our activities relating to the reporting of wholesaler or estimated retail prices for our products, the reporting of prices used to calculate Medicaid
rebate information and other information affecting federal, state and third-party reimbursement for our products, and the sale and marketing of our
products, are subject to scrutiny under this law. For example, several pharmaceutical and other healthcare companies have faced enforcement
actions under these laws for allegedly inflating drug prices they report to pricing services, which in turn were used by the government to set
Medicare and Medicaid reimbursement rates, and for allegedly providing free product to customers with the expectation that the customers would
bill federal programs for the product. The False Claims Act also permits a private individual acting as a “whistleblower” to bring actions on behalf
of the federal government alleging violations of the False Claims Act and to share in any monetary recovery. In addition, federal Anti-Kickback
Statute violations and certain marketing practices, including off-label promotion, may also constitute a violation of the False Claims Act. Although
the False Claims Act is a civil statute, conduct that results in a False Claims Act violation may also implicate various federal criminal statutes.
Additionally, the federal government has pursued electronic health record, or HER, vendors and pharmaceutical manufacturers for remunerative
relationships involving the EHR platform’s recommendation of particular drugs and “prompting” technology to increase prescribing of particular
drugs.

43

 
 
 
 
 
 
 
 
 
● The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes criminal and civil liability for knowingly and
willfully executing, or attempting to execute, a scheme to defraud or to obtain, by means of false or fraudulent pretenses, representations or
promises, any money or property owned by, or under the control or custody of, any healthcare benefit program, including private third-party payors
and knowingly and willfully falsifying, concealing or covering up by trick, scheme or device, a material fact or making any materially false,
fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the federal
Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it to have committed a
violation.

● The Criminal Healthcare Fraud statute, 18 U.S.C. § 1347, prohibits knowingly and willfully executing a scheme to defraud any healthcare benefit
program, including private third-party payers. Federal criminal law at 18 U.S.C. § 1001, among other sections, prohibits knowingly and willfully
falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the
delivery of or payment for healthcare benefits, items or services. These statutes are not limited to items and services reimbursed by a governmental
health care program and have been used to prosecute commercial insurance fraud as well.

● The civil monetary penalties statute imposes penalties against any person or entity that, among other things, is determined to have presented or

caused to be presented a claim to a federal health program that the person knows or should know is for an item or service that was not provided as
claimed or is false or fraudulent.

● The exclusion statute requires the exclusion of entities and individuals who have been convicted of federal-program related crimes or health care
felony fraud or controlled substance charges. The statute also permits the exclusion of those that have been convicted of any form of fraud, the
Anti-Kickback Statute, for obstructing an investigation or audit, misdemeanor controlled substance charges, those whose health care license has
been revoked or suspended, and those who have filed claims for excessive charges or unnecessary services. If a company were to be excluded, its
products would be ineligible for reimbursement from any federal programs, including Medicare and Medicaid, and no other entity participating in
those programs would be permitted to enter into contracts with the company. Further, employment or contracting with an individual or entity that
has been excluded from participation in federal healthcare programs could serve as a basis to invalidate claims for items or services submitted by
that entity and to exclude that entity from participation in such programs as well. In order to preserve access to beneficial drugs, the government
may elect to exclude officers and key employees of manufacturers, rather than excluding the organization. Such enforcement actions would
prohibit us from engaging those individuals, which could adversely affect operations.

44

 
 
 
 
 
 
 
 
 
 
● We may be subject to data privacy and security regulations by both the federal government and the states in which we conduct business. We are not

a covered entity under HIPAA and have not functioned as a business associate under HIPAA that would cause the HIPAA Security Rule and
provisions of the Privacy Rule to apply directly to us as a business associate. To the extent that we ever function in a business associate capacity,
however, HIPAA, as amended by as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH,
and their respective implementing regulations, including the Final Omnibus Rule published on January 25, 2013, impose, among other things,
obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable
health information. HITECH also created four new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly
applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal court to
enforce the federal HIPAA laws and seek attorney’s fees and costs associated with pursuing federal civil actions. The U.S. Department of Health
and Human Services, or HHS, Office for Civil Rights, or the OCR, has increased its focus on compliance and continues to train state attorneys
general for enforcement purposes. The OCR has recently increased both its efforts to audit HIPAA compliance and its level of enforcement, with
one recent penalty exceeding $5 million. In addition, state laws govern the privacy and security of health information in specified circumstances,
many of which differ from each other in significant ways, and may apply more broadly thus complicating compliance efforts (for example,
California recently enacted legislation — the California Consumer Privacy Act, or CCPA — which went into effect on January 1, 2020 and among
other things, created new data privacy obligations for covered companies and provided new privacy rights to California residents, including the
right to opt out of certain disclosures of their information, and created a private right of action with statutory damages for certain data breaches,
thereby potentially increasing risks associated with a data breach; the California Attorney General will issue final regulations, and although the law
includes limited exceptions, including for certain information collected as part of clinical trials as specified in the law, it may regulate or impact our
processing of personal information depending on the context, and it remains unclear what language the final Attorney General regulations will
contain or how the statute and the regulations will be interpreted.

● The federal physician payment transparency requirements, sometimes referred to as the “Physician Payments Sunshine Act,” created under the

U.S. Patient Protection and Affordable Care Act of 2010, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively
the ACA, and its implementing regulations, which requires applicable manufacturers of covered drugs, devices, biologics and medical supplies for
which payment is available under Medicare, Medicaid or the State Children’s Health Insurance Program (with certain exceptions) to annually
report to the Centers for Medicare & Medicaid Services, or CMS, information related to certain payments or other transfers of value made or
distributed to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, or to entities or
individuals at the request of, or designated on behalf of, the physicians and teaching hospitals, as well as ownership and investment interests held
by physicians and their immediate family members. Federal legislation enacted in 2018 has extended the scope of reporting requirements to apply
to payments and transfers of value to not only physicians, but also physician assistants, nurse practitioners, and other mid-level practitioners (with
reporting requirements going into effect in 2022 for payments made in 2021).

● According to the U.S. Federal Trade Commission, or the FTC, failing to take appropriate steps to keep consumers’ personal information secure
constitutes unfair acts or practices in or affecting commerce in violation of Section 5(a) of the Federal Trade Commission Act, or the FTCA, 15
U.S.C § 45(a). The FTC expects a company’s data security measures to be reasonable and appropriate in light of the sensitivity and volume of
consumer information it holds, the size and complexity of its business, and the cost of available tools to improve security and reduce
vulnerabilities. Medical data is considered sensitive data that merits stronger safeguards. The FTC’s guidance for appropriately securing
consumers’ personal information is similar to what is required by the HIPAA Security Rule.

45

 
 
 
 
 
 
 
 
● Analogous state laws and regulations, such as state anti-kickback and false claims laws, may apply to items or services reimbursed by any third-
party payor, including commercial insurers, and in some cases may apply regardless of payor (i.e., even for self-pay scenarios). 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 in addition to requiring drug manufacturers to report pricing and marketing information,
including, among other things, information related to payments to physicians and other healthcare providers or marketing expenditures,
requirements related to drug sample distribution, state and local laws that require the registration of pharmaceutical sales representatives, and state
laws governing the privacy and security of health information and the use of prescriber-identifiable data in certain circumstances, many of which
differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts.

● Price reporting laws that require us to calculate and report complex pricing metrics to government programs, where such reported prices may be

used in the calculation of reimbursements or discounts on our drug products.

Because of the breadth of these laws and the narrowness of the statutory exceptions and regulatory safe harbors available under such laws, it is possible that
certain business activities could be subject to challenge under one or more of such laws. The scope and enforcement of each of these laws is uncertain and
subject to rapid change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and regulations. Federal and
state enforcement bodies have recently increased their scrutiny of interactions between healthcare companies and healthcare providers, which has led to a
number of investigations, prosecutions, convictions and settlements in the healthcare industry. Ensuring that business arrangements with third parties
comply with applicable healthcare laws, as well as responding to possible investigations by government authorities, can be time- and resource-consuming
and can divert management’s attention from the business, even if the government ultimately finds that no violation has occurred.

If our operations are found to be in violation of any of the health regulatory laws described above or any other laws that apply to us, we may be subject to
penalties, including, but not limited to, criminal, civil and administrative penalties, damages, fines, disgorgement, individual imprisonment, possible
exclusion from participation in government healthcare programs, injunctions, private qui tam actions brought by individual whistleblowers in the name of
the government and the curtailment or restructuring of our operations, as well as additional reporting obligations and oversight if we become subject to a
corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, any of which could adversely affect our ability
to operate our business and our results of operations.

Healthcare Reform

A primary trend in the U.S. healthcare industry and elsewhere is cost containment. There have been a number of federal and state proposals during the last
few years regarding the pricing of pharmaceutical and biopharmaceutical products, limiting coverage and reimbursement for drugs and other medical
products, government control and other changes to the healthcare system in the United States. By way of example, in March 2010, the Patient Protection
and Affordable Care Act, or ACA, contained several provisions affecting the pharmaceutical industry:

● the Medicaid Drug Rebate Program requires pharmaceutical manufacturers to enter into and have in effect a national rebate agreement with the
Secretary of the Department of HHS, as a condition of Medicare Part B and Medicaid coverage of the manufacturer’s outpatient drugs furnished to
Medicaid patients;

● in order for a pharmaceutical product to receive federal reimbursement under the Medicare Part B and Medicaid programs or to be sold directly to
U.S.  government  agencies,  the  manufacturer  must  extend  discounts  to  entities  eligible  to  participate  in  the  340B  Drug  Pricing  Program.  The
required 340B discount on a given product is calculated based on the average manufacturer price, or AMP, and Medicaid rebate amounts reported
by the manufacturer;

46

 
 
 
 
 
 
 
 
 
 
 
 
 
 
● the ACA imposed a requirement on manufacturers of branded drugs to provide a 70% discount off the negotiated price of branded drugs dispensed

to Medicare Part D patients in the coverage gap (i.e., the donut hole);

● the ACA imposed an annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs, apportioned among
these  entities  according  to  their  market  share  in  certain  government  healthcare  programs,  although  this  fee  would  not  apply  to  sales  of  certain
products approved exclusively for orphan indications;

● the ACA implemented the Physician Payments Sunshine Act;

● the ACA requires annual reporting of drug samples that manufacturers and distributors provide to physicians;

● the ACA expanded healthcare fraud and abuse laws in the United States, including the False Claims Act and the federal Anti-Kickback Statute,

new government investigative powers and enhanced penalties for non-compliance;

● the ACA established a licensing framework for follow-on biologics; and

● the  ACA  established  the  new  Patient-Centered  Outcomes  Research  Institute  to  oversee,  identify  priorities  in  and  conduct  comparative  clinical

effectiveness research, along with the funding for such research.

The  Trump  Administration  and  the  Congressional  Republicans  have  proposed  several  efforts  to  repeal  and  replace  the  ACA.  President  Trump  has  also
signed Executive Orders and other directives designed to delay the implementation of certain provisions of the ACA or otherwise circumvent some of the
requirements for health insurance mandated by the ACA. Additionally, on December 15, 2019, a federal district court in Texas struck down the ACA in its
entirety, finding that the Tax Cuts and Jobs Act of 2017 (TCJA) rendered the individual mandate unconstitutional. The judge further concluded in Texas v.
Azar that  since  the  individual  mandate  is  “essential”  to  the  ACA,  it  could  not  be  severed  from  the  rest  of  the  ACA  and  therefore,  the  entire  ACA  was
unconstitutional. Despite its decision, however, the court did not issue an injunction and therefore, immediate compliance is not required. In addition, the
Trump Administration announced that it will continue to administer the law until a formal decision is made by the U.S. Supreme Court. The Supreme Court
recently announced that it will hear a challenge in Texas v. United States, though arguments have not yet been set. It is likely that the case will be scheduled
for arguments early in the next term that starts in October 2020. Apart from Texas v. United States, ACA litigation continues across the country in district
and appellate courts, and before the Supreme Court. The Supreme Court will issue at least two ACA-related decisions before the end of its current term: one
on  the  risk  corridors  program  (Maine  Community  Health  Options  v.  United  States)  and  the  other  on  religious  or  moral  exemptions  to  the  contraceptive
mandate (Trump v. Pennsylvania and Little Sisters of the Poor v. Pennsylvania). Both decisions are expected before July 2020. It is unclear how the eventual
decisions from the Supreme Court and the various other courts across the country to repeal and replace the ACA will impact the ACA and our business. It is
also  unclear  how  regulations  and  sub-regulatory  policy,  which  fluctuate  continually,  may  affect  interpretation  and  implementation  of  the  ACA  and  its
practical effects on our business, particularly entering an election year.

In the future, there may continue to be additional proposals relating to the reform of the U.S. healthcare system, some of which could further limit the prices
we will be able to charge for our product candidates, or the amounts of reimbursement available for our product candidates. If future legislation were to
impose direct governmental price controls or access restrictions, it could have a significant adverse impact on our business. Managed care organizations, as
well  as  Medicaid  and  other  government  agencies,  continue  to  seek  price  discounts.  Some  states  have  implemented,  and  other  states  are  considering,
measures to reduce costs of the Medicaid program, and some states are considering implementing measures that would apply to broader segments of their
populations that are not Medicaid-eligible. Due to the volatility in the current economic and market dynamics, we are unable to predict the impact of any
unforeseen or unknown legislative, regulatory, payor or policy actions, which may include cost containment and healthcare reform measures. Such policy
actions could have a material adverse impact on our profitability.

47

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
These and other healthcare reform initiatives may result in additional reductions in Medicare and other healthcare funding, which could have a material
adverse effect on our financial operations. We expect that additional state and 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, which could result in reduced demand for our
product candidates or additional pricing pressures.

Additionally, on May 30, 2018, the Trickett Wendler, Frank Mongiello, Jordan McLinn, and Matthew Bellina Right to Try Act of 2017, or Right to Try Act,
was signed into law. The law, among other things, provides a federal framework for patients to access certain investigational new drug products that have
completed a Phase I clinical trial. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining
FDA approval under the FDA expanded access program. There is no obligation for a pharmaceutical manufacturer to make its drug products available to
eligible patients as a result of the Right to Try Act.

Foreign Regulation of Drugs

In order to market any product outside of the United States, we will need to comply with numerous and varying regulatory requirements of other countries
and jurisdictions regarding development, approval, commercial sales and distribution of our products, and governing, among other things, clinical trials,
marketing authorization, commercial sales and distribution of our products, if approved. Whether or not we obtain FDA approval for a product, we must
obtain the necessary approvals by the comparable regulatory authorities of foreign countries before we can commence clinical trials or marketing of the
product  in  those  countries.  The  approval  process  varies  between  countries  and  jurisdictions  and  can  involve  additional  product  testing  and  additional
administrative review periods. The time required to obtain approval in other countries and jurisdictions might differ from and be longer than that required to
obtain FDA approval. Regulatory approval in one country or jurisdiction does not ensure regulatory approval in another, but a failure or delay in obtaining
regulatory approval in one country or jurisdiction may negatively impact the regulatory process in others.

Item 1A. Risk Factors

Investing in our common stock involves a high degree of risk. You should carefully consider the risks described below, as well as the other information in
this Annual Report on Form 10-K, including our financial statements and the related notes and “Management’s Discussion and Analysis of Financial
Condition and Results of Operations,” before deciding whether to invest in our common stock. The occurrence of any of the events or developments
described below could harm our business, financial condition, results of operations and growth prospects. In such an event, the market price of our common
stock could decline and you may lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem
immaterial also may impair our business operations.

Risks Related to our Financial Position and Need for Additional Capital

Our net losses and significant cash used in operating activities have raised substantial doubt regarding our ability to continue as a going concern.

Our  financial  statements  for  the  year  ended  December  31,  2019  include  a  statement  that  our  recurring  losses  and  cash  outflows  from  operations,  our
accumulated deficit and our debt maturing within twelve months raise substantial doubt about our ability to continue as a going concern. As of December
31,  2019,  we  had  $55.8  million  of  cash.  We  believe  that  our  existing  cash  will  enable  us  to  fund  our  operating  expenses  and  capital  expenditure
requirements, make payments of interest and principal on our term loan facility with Pacific Western Bank, or PWB, and remain in compliance with the
minimum cash covenant of $8.5 million pursuant to this term loan facility, through August 2020. We have based these estimates on assumptions that may
prove to be wrong, and we could utilize our available capital resources sooner than we expect.

If we are unable to obtain sufficient funding or execute on strategic initiatives to generate sufficient cash, our business, prospects, financial condition and
results of operations will be materially and adversely affected, and we may be unable to continue as a going concern. If we are unable to continue as a going
concern, we may have to liquidate our assets and may receive less than the value at which those assets are carried on our audited financial statements, and it
is likely that investors will lose all or a part of their investment. Future financial statements may also include statements expressing substantial doubt about
our ability to continue as a going concern. If we seek additional financing to fund our business activities in the future and there remains substantial doubt
about our ability to continue as a going concern, investors or other financing sources may be unwilling to provide additional funding to us on commercially
reasonable terms or at all.

We have a history of losses, have not commenced commercial operations to date and our future profitability is uncertain.

We have incurred net losses of $47.6 million, $53.1 million and $29.2 million for the years ended December 31, 2019, 2018 and 2017, respectively. We also
had  negative  operating  cash  flows  for  each  of  these  years.  As  of  December  31,  2019  and  2018,  we  had  an  accumulated  deficit  of  $215.2  million  and
$167.1 million, respectively.

Since our incorporation, we have invested heavily in the development of our product candidates and technologies, as well as in recruiting management and
scientific personnel. To date, we have not commenced the commercialization of our product candidates and all of our revenue has been derived from up-
front fees and milestone payments made to us in connection with licensing and collaboration arrangements we have entered into. These up-front fees and
milestone payments have been, and may continue to be, insufficient to match our operating expenses. We expect to continue to devote substantial financial
and  other  resources  to  the  clinical  development  of  our  product  candidates  and,  as  a  result,  must  generate  significant  revenue  to  achieve  and  maintain
profitability. We may continue to incur losses and negative cash flow and may never transition to profitability or positive cash flow.

49

 
 
 
 
 
 
 
 
 
 
 
We expect that we will need further financing for our existing business and future growth, which may not be available on acceptable terms, if at all.
Failure to obtain funding on acceptable terms and on a timely basis may require us to curtail, delay or discontinue our product development efforts or
other  operations.  The  failure  to  obtain  further  financing  may  also  prevent  us  from  capitalizing  on  other  potential  product  candidates  or  indications
which may be more profitable than LIQ861 and LIQ865 or for which there may be a greater likelihood of success.

We  anticipate  that  we  will  need  to  raise  additional  funds  to  meet  our  future  funding  requirements  for  the  continued  research,  development  and
commercialization  of  our  product  candidates  and  technology.  In  the  event  that  funds  generated  from  our  operations  are  insufficient  to  fund  our  future
growth,  we  may  raise  additional  funds  through  the  issuance  of  equity  or  debt  securities  or  by  borrowing  from  banks  or  other  financial  institutions.  We
cannot assure you that we will be able to obtain such additional financing on terms that are acceptable to us, or at all. Global and local economic conditions
could negatively affect our ability to raise funds. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your
ownership  interest  will  be  diluted,  and  the  terms  of  such  securities  may  include  liquidation  or  other  preferences  that  adversely  affect  your  rights  as  a
stockholder. Such financing, even if obtained, may be accompanied by restrictive covenants that may, among others, limit our ability to pay dividends or
require us to seek consent for payment of dividends, or restrict our freedom to operate our business by requiring consent for certain actions.

If we fail to obtain additional financing on terms that are acceptable to us, we will not be able to implement our growth plans, and we may be required to
significantly curtail, delay or discontinue one or more of our research, development or manufacturing programs or the commercialization of any approved
product.  Furthermore,  if  we  fail  to  obtain  additional  financing  on  terms  that  are  acceptable  to  us,  we  may  forgo  or  delay  the  pursuit  of  opportunities
presented by other potential product candidates or indications that may later prove to have greater commercial potential than the product candidates and
indications that we have chosen to pursue.

We are evaluating potential strategic alternatives that could significantly impact our future operations and financial position.

Our  primary  objective  has  been  to  pursue  marketing  approval  of  LIQ861  and  commercialize  such  product  if  approved  by  FDA.  We  will  need  to  raise
substantial additional capital to continue our business operations and remain in compliance with the minimum cash covenant on our debt during and beyond
the third quarter of 2020, in addition to commercializing LIQ861, if approved. Such capital may not be available to us on a timely basis, on terms that are
favorable to us, or at all. Alternatively, in light of the Company’s current limited cash resources, the recent trading price of our common stock, outstanding
debt and associated minimum cash covenant, and based on a review of the status of our programs, resources and capabilities, we continue to explore a wide
range of strategic alternatives with the support of our financial advisor, Jefferies LLC, that could maximize stockholder value. Our efforts have been and
continue to be focused primarily upon the potential formation of a partnership or a licensing transaction with respect to our lead program, LIQ861, for the
treatment of PAH. Strategic alternatives may also include the sale of some of our assets or proprietary technologies, or a potential merger or sale of the
Company. There can be no assurance that we will be able to enter into such a transaction or transactions on a timely basis, on terms that are favorable to us,
or at all.

We may acquire businesses, products or product candidates, or form strategic alliances or create joint ventures, in the future, and we may not realize the
benefits of such transactions.

We may acquire additional businesses, products or product candidates, form strategic alliances or create joint ventures with third parties that we believe will
complement or augment our existing business, although we have no current agreements, commitments or understandings to do so. If we acquire businesses
with promising markets or technologies, we may not be able to realize the benefit of acquiring such businesses if we are unable to successfully integrate
them  with  our  existing  operations  and  company  culture.  We  may  encounter  numerous  difficulties  in  developing,  manufacturing  and  marketing  any  new
products or product candidates resulting from a strategic alliance or acquisition that delay or prevent us from realizing their expected benefits or enhancing
our business. We cannot assure you that, following any such acquisition, strategic alliance or joint venture, we will achieve the expected synergies to justify
the transaction. 

Our credit facility with Pacific Western Bank, or PWB, contains operating and financial covenants that restrict our business and financing activities,
and is subject to acceleration in specified circumstances, which may result in PWB taking possession and disposing of any collateral.

Our credit facility contains restrictions that limit our flexibility in operating our business. Under the terms of the amended and restated loan and security
agreement dated as of October 26, 2018, as amended, or the A&R LSA, with PWB, pursuant to which PWB extended a $16.0 million term loan facility to
us,  of  which  $11.0  million  was  received  in  October  2018  in  an  initial  tranche  and  $5.0  million  was  received  in  May  2019,  we  may  not,  among  others,
without the prior written consent of PWB, (a) pay any dividends or make any other distribution or payment on account of or in redemption, retirement or
purchase  of  any  capital  stock  except  in  certain  prescribed  circumstances,  (b)  create,  incur,  assume,  guarantee  or  be  or  remain  liable  with  respect  to  any
indebtedness except certain permitted indebtedness or prepay any indebtedness, (c) replace or suffer the departure of our Chief Executive Officer or Chief
Financial Officer without delivering written notification to PWB within ten days of such change or (d) suffer a change on our board of directors, or Board,
which results in the failure of at least one partner of Canaan Partners or their respective affiliates to serve as a voting member, without having used best
efforts to deliver at least 15 days’ prior written notification to PWB. Our facility with PWB is collateralized by all of our assets excluding our intellectual
property, on which we have granted a negative pledge.

50

 
 
 
 
 
 
 
 
 
 
 
We have, in the past, breached multiple covenants in our loan and security agreement dated as of January 6, 2016, as amended, with PWB related to cash
levels,  reporting  requirements  and  required  periodic  deliverables  to  PWB,  but  have  obtained  waivers  from  PWB  in  relation  to  all  such  breaches.  If  we
breach certain of our debt covenants and are unable to cure such breach within the prescribed period or are not granted waivers in relation to such breach, it
may constitute an event of default under our facility agreements, giving lenders the right to require us to repay the then outstanding debt immediately, and
the  lenders  could,  among  other  things,  foreclose  on  the  collateral  granted  to  them  to  collateralize  such  indebtedness,  which  excludes  our  intellectual
property,  if  we  are  unable  to  pay  the  outstanding  debt  immediately.  A  breach  of  covenants  in  the  A&R  LSA  and  the  acceleration  of  our  repayment
obligations by PWB could have a material adverse effect on our business, financial condition, results of operations and prospects.

Although we have historically depended on GSK for a significant portion of our revenue, we do not expect to receive any additional revenue from our
GSK collaboration.

We  are  party  to  a  licensing  agreement  with  GSK  pursuant  to  which  GSK  has  exercised  an  option  to  exclusively  license  our  PRINT  technology  for
applications in certain inhaled therapies, or the GSK ICO Agreement. We previously entered into a separate licensing agreement with GSK relating to the
field  of  vaccines,  which  lapsed  in  April  2016.  We  have  historically  received  a  significant  portion  of  our  revenue  from  GSK  pursuant  to  these  licensing
agreements. For the years ended December 31, 2019, 2018 and 2017, our revenue attributable to our collaboration and licensing arrangements with GSK,
which included a combination of billings for particle formulations, manufacturing, milestone payments and amortization of deferred revenue from up-front
fees, accounted for 100%, 16% and 84%, respectively, of our total revenue.

During  the  second  quarter  of  2019  we  concluded  that  no  further  research  and  development  services  will  be  provided  to  GSK  under  the  collaboration
agreement  and  the  earnings  process  related  to  the  license  fees  previously  received  under  the  collaboration  agreement  has  been  completed  under  the
proportional performance model. Therefore, the remaining deferred revenue of $8.1 million was recognized as revenue during the second quarter of 2019,
and  we  do  not  expect  to  receive  any  additional  revenue  from  GSK  pursuant  to  our  collaboration.  Because  GSK  is  no  longer  actively  advancing  any
programs under our collaboration, we entered into the Third Amendment to the GSK ICO Agreement during the second quarter of 2019, pursuant to which
we have the right to develop three products for delivery via inhalation, subject to specified milestone payments and royalties due to GSK. Additionally,
under certain circumstances GSK has a right of first negotiation with respect to these programs. Although a large proportion of our revenue has historically
been obtained from our collaboration with GSK, we do not expect this collaboration to continue. To that end, we recently notified GSK of our intent to
terminate the collaboration because we believe that GSK's inactivity with respect to the collaboration constitutes a material breach and GSK has rebutted
our notice of termination. We are currently attempting to resolve the dispute with GSK pursuant to the terms of the GSK ICO Agreement.

Our management has broad discretion in using the net proceeds from prior equity offerings and may not use them effectively.

We  expect  to  use  the  net  proceeds  of  prior  equity  offerings  to  conduct  additional  clinical  studies  for  LIQ861,  conduct  toxicology  studies  for  LIQ865
and advance LIQ865 towards one or more Phase 2 proof-of-concept clinical trials, fund operations supporting the development of, and commercial activities
for, LIQ861 and LIQ865, and for working capital and general corporate purposes. Our management has broad discretion in the application of such proceeds
and could spend the proceeds in ways that do not improve our results of operations or enhance the value of our equity. The failure by our management to
apply  these  funds  effectively  could  result  in  financial  losses  that  could  have  a  material  adverse  effect  on  our  business,  diminish  cash  flows  available  to
service  our  debt,  cause  the  value  of  our  equity  to  decline  and  delay  the  development  of  our  product  candidates.  Pending  their  use,  we  may  invest  such
proceeds in short-term, investment-grade, interest-bearing securities, which may not yield favorable returns.

51

 
 
 
 
 
 
 
 
Our ability to use our net operating loss carry forwards and certain other tax attributes may be limited.

Under Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, if a corporation undergoes an “ownership change”, generally defined as
a greater than 50.0% change (by value) in its equity ownership over a three-year period, the corporation’s ability to use its pre-change net operating loss
carryforwards and other pre-change tax attributes, such as research tax credits, to offset its post-change income may be limited. With our December 2019
private placement and recent issuances under our ATM facility, our March 2019 follow-on equity offering and our July 2018 initial public offering, as well
as other past transactions, we believe that we have triggered an “ownership change” limitation. We have not completed a formal study to determine if any
“ownership changes” within the meaning of IRC Section 382 have occurred. If “ownership changes” within the meaning of Section 382 of the Code have
occurred, and if we earn net taxable income, our ability to use our net operating loss carryforwards and research and development tax credits generated since
inception to offset U.S. federal taxable income may be subject to limitations, which could potentially result in increased future tax liability to us and could
require us to pay U.S. federal income taxes earlier than would be required if such limitations were not in effect. Similar rules and limitations may apply for
state income tax purposes.

We are a late-stage clinical biopharmaceutical company with no approved products and no historical product revenue, which may make it difficult for
you to evaluate our business, financial condition and prospects.

We are a late-stage clinical biopharmaceutical company with no history of commercial operations upon which you can evaluate our prospects. Drug product
development  involves  a  substantial  degree  of  uncertainty.  Our  operations  to  date  have  been  limited  to  developing  our  PRINT  technology,  undertaking
preclinical studies and clinical trials for our product candidates and collaborating with pharmaceutical companies, including GlaxoSmithKline plc and/or its
subsidiaries, collectively, GSK, to expand the applications for our PRINT technology through licensing as well as joint product development arrangements.
We have not obtained marketing approval for any of our product candidates and, accordingly, have not demonstrated an ability to generate revenue from
pharmaceutical products or successfully overcome the risks and uncertainties frequently encountered by companies undertaking drug product development.
Consequently, your ability to assess our business, financial condition and prospects may be significantly limited. Further, the net losses that we incur may
fluctuate  significantly  from  quarter-to-quarter  and  year-to-year,  such  that  a  period-to-period  comparison  of  our  results  of  operations  may  not  be  a  good
indication of our future performance. Other unanticipated costs may also arise.

The TCJA could adversely affect our business and financial condition.

On  December  22,  2017,  the  TCJA  was  enacted  into  law.  The  TCJA  includes  significant  changes  to  the  U.S.  corporate  income  tax  system,  including  a
permanent reduction in the corporate income tax rate from 35% to 21%, limitations on the deductibility of interest expense and executive compensation and
the transition of U.S. international taxation from a worldwide system to a territorial tax system. For taxpayers with revenues over a certain threshold, the
TCJA also limits interest expense deductions to 30% of taxable income before interest, depreciation and amortization from 2018 to 2021 and then taxable
income before interest thereafter. The TCJA permits disallowed interest expense to be carried forward indefinitely. We calculated our best estimate of the
impact of the TCJA in our income tax provision for the year ended December 31, 2017 in accordance with our understanding of the TCJA and guidance
available  at  the  time.  The  overall  impact  of  the  TCJA  resulted  in  a  decrease  to  the  deferred  tax  assets  and  a  corresponding  decrease  to  the  valuation
allowance of $14.1 million. We completed our accounting for the TCJA during the fourth quarter of 2018. No changes to the provisional amounts as of
December 31, 2017 were recorded. Notwithstanding the reduction in the corporate income tax rate, the overall impact of the TCJA is uncertain and our
business and financial condition could be adversely affected. The impact of this tax reform on holders of our common stock is also uncertain and could be
adverse.  We  urge  our  stockholders  to  consult  with  their  legal  and  tax  advisors  with  respect  to  such  legislation  and  the  potential  tax  consequences  of
investing in our common stock.

52

 
 
 
 
 
 
 
 
Risks Related to the Commercialization of our Product Candidates

We face significant competition from large pharmaceutical companies, among others, and our operating results will suffer if we are unable to compete
effectively.

We  face  significant  competition  from  industry  players  worldwide,  including  large  multi-national  pharmaceutical  companies,  other  emerging  or  smaller
pharmaceutical companies, as well as universities and other research institutions. Many of our competitors have substantially greater financial, technical and
other  resources,  such  as  a  larger  research  and  development  staff,  and  more  experience  in  manufacturing  and  marketing,  than  we  do.  As  a  result,  these
companies may obtain marketing approval for their product candidates more quickly than we are able to and be more successful in commercializing their
products than us. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaboration arrangements with large,
established companies. We may also face competition as a result of advances in the commercial applicability of new technologies and greater availability of
capital for investment in such technologies. Our competitors may also invest heavily in the discovery and development of novel drug products that could
make  our  product  candidates  less  competitive  or  may  file  FDA  citizen  petitions  which  may  delay  the  approval  process  for  our  product  candidates.
Furthermore, our competitors may succeed in developing, acquiring or licensing, on an exclusive basis, pharmaceutical products that are easier to develop,
more effective or less costly than any product candidates that we are currently developing or that we may develop. Our competitors may also succeed in
asserting existing patents or developing new patents to which we do not have a license in an attempt to prevent us from marketing our products.

Any new drug product that competes with a prior approved drug product must demonstrate advantages in safety, efficacy, tolerability or convenience in
order to overcome price competition and to be commercially successful. Our products, if and when approved, are expected to face competition from drug
products that are already on the market, as well as those in our competitors’ development pipelines. We expect that our lead program, LIQ861, an inhaled
treprostinil therapy for the treatment of PAH, will face competition from the following inhaled treprostinil therapies that are either currently marketed or in
clinical development:

● Tyvaso, marketed by United Therapeutics, has been approved for the treatment of PAH in the United States since 2009. Tyvaso is the reference
listed drug in our NDA for LIQ861. Following patent litigation, United Therapeutics and Watson Pharmaceuticals reached a settlement whereby
Watson Pharmaceuticals will be permitted to enter the market with a generic version of Tyvaso beginning on January 1, 2026.

● Ventavis, marketed by Actelion, a division of Johnson & Johnson, has been approved for the treatment of PAH in the United States since 2004.

● TreT, licensed from MannKind, by United Therapeutics, is currently in late-stage clinical development in the United States for the treatment of
PAH. Under the license agreement, United Therapeutics is responsible for global development, regulatory and commercial activities. MannKind
will manufacture clinical supplies and initial commercial supplies of the product while long-term commercial supplies will be manufactured by
United Therapeutics. In September, 2019, United Therapeutics commenced a clinical study (BREEZE) to evaluate the safety and pharmacokinetics
of switching PAH patients from Tyvaso to TreT and announced plans to commence a second clinical study during the first half of 2020 to compare
the pharmacokinetics of TreT to Tyvaso in healthy volunteers. United Therapeutics further reported that the two studies, if successful, are the only
clinical studies necessary to support FDA approval.

In  addition  to  these  other  inhaled  treprostinil  therapies,  we  expect  that  LIQ861  will  also  face  competition  from  other  treprostinil-based  drugs,  including
Orenitram, which is administered orally, and Remodulin, which is administered parenterally, both of which are marketed by United Therapeutics.

In addition to treprostinil-based therapies, other classes of therapeutic agents for the treatment of PAH include the following:

● IP-agonists,  such  as  selexipag,  marketed  by  Actelion,  and  ralinepeg,  licensed  from  Arena  Pharmaceuticals  by  United  Therapeutics,  which  is

currently in clinical development;

● Endothelin  receptor  antagonists,  such  as  bosentan  and  macitentan,  both  marketed  by  Actelion,  and  ambrisentan,  marketed  by  Gilead.  Generic

version of bosentan and ambrisentan are currently available.

● PDE-5 inhibitors, such as tadalafil, marketed by United Therapeutics, and sildenafil, marketed by Pfizer. Generic versions of both tadalafil and

sildenafil are currently available.

● Soluble guanylate cyclase (sGC) stimulator, such as riociguat marketed by Bayer.

53

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In addition, we are also aware of several other agents currently in clinical development in the United States for the treatment of PAH, including those in
development by Insmed and Acceleron.

We  expect  LIQ865  to  face  competition  from  EXPAREL®,  an  existing  injectable  version  of  bupivacaine.  The  early  success  of  EXPAREL  may  make  it
difficult  for  us  to  convince  physicians,  patients  and  other  members  of  the  medical  community  to  accept  and  use  LIQ865  over  EXPAREL.  Generic
equivalents of EXPAREL may also enter the market following the expiry of EXPAREL’s patent in 2021.

While  EXPAREL  is  currently  the  only  direct  competitor  to  LIQ865  on  the  market,  in  October  2018  Heron  Therapeutics,  Inc.,  or  Heron,  announced  the
submission of its NDA to the FDA for HTX-011, an investigational long-acting, extended-release formulation of the local anesthetic bupivacaine in a fixed-
dose combination with the anti-inflammatory meloxicam for the management of postoperative pain. HTX-011 was granted both breakthrough therapy and
fast track designations from the FDA as well as priority review by the FDA. On May 1, 2019, Heron announced that it received a complete response letter,
or CRL, for HTX-011 from the FDA. On October 1, 2019, Heron announced that it had resubmitted its NDA for HTX-011 to the FDA and expected a six-
month  review.  In  addition  to  Heron,  Durect  Corporation  and  Innocoll  Holdings  plc  each  also  have  products  in  clinical  development  that  are  potential
competitors to LIQ865.

If we are unable to maintain our competitive position, our business and prospects will be materially and adversely affected.

If a competitor obtains orphan drug designation from the FDA for the same drug and same indication as we are seeking for a product candidate, and
then obtains approval of that drug for that condition before we do, the resulting FDA exclusivity would significantly delay our ability to commercialize
that product candidate. Similarly, if a competitor obtains marketing approval for a new condition of use that required new clinical investigations for
support,  the  competitor  may  obtain  three-year  marketing  exclusivity  for  that  condition  of  use,  and  thereby  delay  our  ability  to  receive  marketing
approval for that drug product for that condition of use by three years form the date of that approval.

Under the Orphan Drug Act, the FDA may grant orphan drug designation to drugs intended to treat a rare disease or condition — generally a disease or
condition that affects fewer than 200,000 individuals in the United States or that affects more than 200,000 individuals in the United States and for which
there is no reasonable expectation that the costs of research and development of the drug for the indication can be recovered by sales of the drug in the
United States. Orphan drug designation must be requested before submitting an NDA.

After the FDA grants orphan drug designation, the generic identity of the drug and its potential orphan use are disclosed publicly by the FDA. Orphan drug
designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process. The first applicant to receive FDA
approval  for  a  particular  active  ingredient  to  treat  a  particular  disease  or  condition  with  orphan  drug  designation  is  entitled  to  a  seven-year  exclusive
marketing period in the United States for that product in that indication. Among the other benefits of orphan drug designation are tax credits for certain
research and a waiver of the NDA application user fee.

During the exclusivity period, the FDA may not approve any other applications to market the same drug for the same disease or condition, except in limited
circumstances,  such  as  if  the  second  applicant  demonstrates  clinical  superiority  of  its  product  to  the  product  with  orphan  drug  exclusivity  through  a
demonstration of superior safety, superior efficacy or a major contribution to patient care, or if the manufacturer of the product with orphan exclusivity is
not able to assure sufficient quantities of the product. “Same drug” means a drug that contains the same identity of the active moiety if it is a drug composed
of small molecules, or of the principal molecular structural features if it is composed of macromolecules and is intended for the same use as a previously
approved drug, except that if the subsequent drug can be shown to be clinically superior to the first drug, it will not be considered to be the same drug. Drug
exclusivity  does  not  prevent  the  FDA  from  approving  a  different  drug  for  the  same  disease  or  condition,  or  the  same  drug  for  a  different  disease  or
condition.

54

 
 
 
 
 
 
 
 
 
 
The commercial success of our drug products depends on the availability and sufficiency of third-party payor coverage and reimbursement.

Patients in the United States and elsewhere generally rely on third-party payors to reimburse part or all of the costs associated with their prescription drugs.
Accordingly,  market  acceptance  of  our  drug  products  is  dependent  on  the  extent  to  which  third-party  coverage  and  reimbursement  is  available  from
government health administration authorities (including in connection with government healthcare programs, such as Medicare and Medicaid in the United
States), private healthcare insurers and other healthcare funding organizations.

Significant uncertainty exists as to the coverage and reimbursement status of any drug products for which we may obtain regulatory approval. Coverage
decisions may not favor new drug products when more established or lower-cost therapeutic alternatives are already available. Even if we obtain coverage
for a given drug product, the associated reimbursement rate may not be adequate to cover our costs, including research, development, intellectual property,
manufacture,  sale  and  distribution  expenses,  or  may  require  co-payments  that  patients  find  unacceptably  high.  Patients  are  unlikely  to  use  our  products
unless reimbursement is adequate to cover all or a significant portion of the cost of our drug products.

Coverage  and  reimbursement  policies  for  drug  products  can  differ  significantly  from  payor  to  payor  as  there  is  no  uniform  policy  of  coverage  and
reimbursement for drug products among third-party payors in the United States. There may be significant delays in obtaining coverage and reimbursement
as  the  process  of  determining  coverage  and  reimbursement  is  often  time-consuming  and  costly,  which  will  require  us  to  provide  scientific  and  clinical
support for the use of our products to each payor separately, with no assurance that coverage or adequate reimbursement will be obtained. It is difficult to
predict at this time what government authorities and third-party payors will decide with respect to coverage and reimbursement for our drug products.

The market for our product candidates will depend significantly on access to third-party payors’ drug formularies, or lists of medications for which third-
party payors provide coverage and reimbursement. Competition to be included in such formularies often leads to downward pricing pressures. In particular,
third-party  payors  may  refuse  to  include  a  particular  drug  in  their  formularies  or  otherwise  restrict  patient  access  to  a  drug  when  a  less  costly  generic
equivalent  or  other  alternative  is  available.  In  particular,  given  that  several  therapeutically  similar  drug  products  to  LIQ861,  including  inhaled,  oral  and
parenteral prostacyclins, are available on the market, managed care organizations may minimize the utilization of a new to market product and accordingly,
we  expect  that  LIQ861,  if  and  when  approved,  will  operate  in  a  highly  cost-constrained  environment.  Similarly,  as  there  are  a  number  of  generic  and
branded therapeutic alternatives to LIQ865 in the post-operative pain market, there is a significant risk that LIQ865 may not be placed on the formularies of
key institutions and/or receive favorable reimbursement, if and when approved.

The U.S. government, state legislatures and foreign governmental entities have shown significant interest in implementing cost containment programs to
limit the growth of government-paid healthcare costs, including price controls, restrictions on reimbursement and coverage and requirements for substitution
of generic products for branded prescription drugs. Adoption of government controls and measures, and tightening of restrictive policies in jurisdictions
with existing controls and measures, could exclude or limit our drug products from coverage and limit payments for pharmaceuticals.

In  addition,  we  expect  that  the  increased  emphasis  on  managed  care  and  cost  containment  measures  in  the  United  States  by  third-party  payors  and
government  authorities  will  continue  and  will  place  pressure  on  pharmaceutical  pricing  and  coverage.  Coverage  policies  and  third-party  reimbursement
rates  may  change  at  any  time.  Even  if  favorable  coverage  and  reimbursement  status  is  attained  for  one  or  more  drug  products  for  which  we  receive
regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

If we are unable to obtain and maintain sufficient third-party coverage and adequate reimbursement for our drug products, the commercial success of our
drug products may be greatly hindered and our financial condition and results of operations may be materially and adversely affected.

Our products may not achieve market acceptance.

We are currently focused on developing drug products that can be approved under abbreviated regulatory pathways in the United States, such as the 505(b)
(2)  regulatory  pathway,  which  allows  us  to  rely  on  existing  knowledge  of  the  safety  and  efficacy  of  the  relevant  reference  listed  drugs  to  support  our
applications for approval in the United States. While we believe that it will be less difficult for us to convince physicians, patients and other members of the
medical community to accept and use our drug products as compared to entirely new drugs, our drug products may nonetheless fail to gain sufficient market
acceptance  by  physicians,  patients,  other  healthcare  providers  and  third-party  payors.  If  any  of  our  drug  products  fail  to  achieve  sufficient  market
acceptance, we may not be able to generate sufficient revenue to become profitable. The degree of market acceptance of our drug products, if and when they
are approved for commercial sale, will depend on a number of factors, including but not limited to:

● the timing of our receipt of marketing approvals, the terms of such approvals and the countries in which such approvals are obtained;
● the safety, efficacy, reliability and ease of administration of our drug products;
● the prevalence and severity of undesirable side effects and adverse events;
● the extent of the limitations or warnings required by the FDA or comparable regulatory authorities in other countries to be contained in the labeling

of our drug products;

● the clinical indications for which our drug products are approved;
● the availability and perceived advantages of alternative therapies;
● any publicity related to our drug products or those of our competitors;
● the quality and price of competing drug products;
● our ability to obtain third-party payor coverage and sufficient reimbursement;
● the willingness of patients to pay out of pocket in the absence of third-party payor coverage; and
● the selling efforts and commitment of our commercialization collaborators.

If our drug products, if and when approved, fail to receive a sufficient level of market acceptance, our ability to generate revenue from sales of our drug
products will be limited, and our business and results of operations may be materially and adversely affected.

The pharmaceutical industry is subject to rapid technological change, which could affect the commercial viability of our products.

The pharmaceutical industry is subject to rapid and significant technological change. Research, discoveries or inventions by others may result in medical
insights  or  breakthroughs  that  render  our  products  less  competitive  or  even  obsolete.  Furthermore,  there  may  be  breakthroughs  of  new  pharmaceutical
technologies which may become superior to our PRINT technology that may result in the loss of our commercial advantage. Our future success will depend
in part upon our ability to, among others:

● develop or license new technologies that address the changing needs of the medical community; and

● respond to technological advances and changing industry standards and practices in a cost-effective and timely manner.

Developing  technology  entails  significant  technical  and  business  risks  and  substantial  costs.  We  cannot  assure  you  that  we  will  be  able  to  utilize  new
technologies effectively or that we will be able to adapt our existing technologies to changing industry standards in a timely or cost-effective manner, or at
all. If we are unable to keep up with advancements in technology, our competitive position may suffer and our business and prospects may be materially and
adversely affected.

Disruptions  at  the  FDA,  the  SEC  and  other  government  agencies  could  hinder  their  ability  to  hire  and  retain  key  leadership  and  other  personnel,
prevent new products and services from being developed or commercialized in a timely manner or otherwise prevent those agencies from performing
normal business functions on which the operation of our business may rely, which could negatively impact our business.

The  ability  of  the  FDA  to  review  and  approve  new  products  can  be  affected  by  a  variety  of  factors,  including  global  pandemics,  natural  disasters,
geopolitical  actions,  government  budget  and  funding  levels,  ability  to  hire  and  retain  key  personnel  and  accept  the  payment  of  user  fees,  and  statutory,
regulatory, and policy changes. Average review times at the FDA have fluctuated in recent years as a result. In addition, government funding of the SEC and
other  government  agencies  on  which  our  operations  may  rely,  including  those  that  fund  research  and  development  activities,  is  subject  to  the  political
process, which is inherently fluid and unpredictable.

Disruptions  at  the  FDA  and  other  agencies  may  also  slow  the  time  necessary  for  new  drugs  to  be  reviewed  and/or  approved  by  necessary  government
agencies, which would adversely affect our business. For example, in December 2019, a novel strain of COVID-19, or coronavirus, was reported to have
surfaced in Wuhan, China and has become a global pandemic as of the date of this Annual Report on Form 10-K. The full impact of the coronavirus is
unknown and rapidly evolving. Additionally, over the last several years, including from December 22, 2018 until January 25, 2019, the U.S. government has
shut  down  several  times  and  certain  regulatory  agencies,  such  as  the  FDA  and  the  SEC,  have  had  to  furlough  critical  FDA,  SEC  and  other  government
employees and stop critical activities. If a prolonged government disruption occurs, it could significantly impact the ability of the FDA to timely review and
process our regulatory submissions, which could have a material adverse effect on our business. Further, in our operations as a public company, prolonged
government disruptions, global pandemics and other natural disasters or geopolitical actions could impact our ability to access the public markets and obtain
necessary capital in order to properly capitalize and continue our operations.

Our products may be subject to reduced prices negotiated by certain group purchasing organizations that could adversely impact our product revenue.

Our customers may organize with each other or with third parties, such as distributors, manufacturers or hospitals, to negotiate prices that are lower than we
may  have  been  able  to  obtain  from  each  of  them  individually.  In  such  event,  our  ability  to  generate  product  revenue,  and  consequently  our  results  of
operations, may be materially and adversely affected.

We may not be able to build our marketing and sales capabilities or enter into agreements with third parties to market and sell our drug products.

In order to market and sell any of our drug products, if and when approved, we will be required to build our marketing and sales capabilities. We cannot
assure you that we will be successful in doing so or be able to do so in a cost-effective manner. In addition, we may enter into collaboration arrangements
with third parties to market our drug products. We may face significant competition for collaborators. In addition, collaboration arrangements may be time-
consuming  to  negotiate  and  document.  We  cannot  assure  you  that  we  will  be  able  to  negotiate  collaborations  for  the  marketing  and  sales  of  our  drug
products  on  acceptable  terms,  or  at  all.  Even  if  we  do  enter  into  such  collaborations,  we  cannot  assure  you  that  our  collaborators  will  be  successful  in
commercializing  our  products.  If  we  or  our  collaborators  are  unable  to  successfully  commercialize  our  drug  products,  whether  in  the  United  States  or
elsewhere, our business and results of operations may be materially and adversely affected.

If the FDA or comparable regulatory authorities in other countries approve generic versions of our product candidates, or do not grant our product
candidates a sufficient period of market exclusivity before approving their generic versions, our ability to generate revenue may be adversely affected.

Once an NDA is approved, the drug product covered will be listed as a reference listed drug in the FDA’s Orange Book. In the United States, manufacturers
of drug products may seek approval of generic versions of reference listed drugs through the submission of abbreviated new drug applications, or ANDAs.
In  support  of  an  ANDA,  a  generic  manufacturer  is  generally  required  to  show  that  its  product  has  the  same  active  pharmaceutical  ingredient(s),  dosage
form,  strength,  route  of  administration  and  conditions  of  use  or  labeling  as  the  reference  listed  drug  and  that  the  generic  version  is  bioequivalent  to  the
reference  listed  drug.  Generic  drug  products  may  be  significantly  less  expensive  to  bring  to  market  than  the  reference  listed  drug,  and  companies  that
produce generic drug products are generally able to offer them at lower prices. Thus, following the introduction of a generic drug product, a significant
percentage of the sales of any reference listed drug may be lost to the generic drug product.

The FDA will not approve an ANDA for a generic drug product until the applicable period of market exclusivity for the reference listed drug has expired.
The applicable period of market exclusivity varies depending on the type of exclusivity granted. A grant of market exclusivity is separate from the existence
of  patent  protection  and  manufacturers  may  seek  to  launch  generic  versions  of  our  drug  products  following  the  expiry  of  their  respective  marketing
exclusivity periods, even if our drug products are still under patent protection at the relevant time.

Any competition that our product candidates may face, if and when such product candidates are approved for marketing and commercialized, from generic
versions could substantially limit our ability to realize a return on our investment in the development of our product candidates and have a material and
adverse effect on our business and prospects.

The off-label use or misuse of our products may harm our image in the marketplace, result in injuries that lead to costly product liability suits, or result
in costly investigations and regulatory agency sanctions under certain circumstances if we are deemed to have engaged in the promotion of these uses,
any of which could be costly to our business.

We are developing LIQ861 for the treatment of PAH and LIQ865 for the treatment of local post-operative pain. If our product candidates receive marketing
approval from the FDA for these specific indications, we may only promote or market our product candidates for their specifically approved indications and
make promotional claims consistent with the FDA-required product labeling. We will train our marketing and sales force against promoting our product
candidates  for  “off-label  uses”  that  would  be  inconsistent  with  FDA  law  and  guidance.  With  respect  to  whether  communications  are  consistent  with  the
FDA-required product labeling, we cannot predict whether the FDA will agree with our assessment. We also cannot prevent a physician from using our
products off-label, when in the physician’s independent professional medical judgment he or she deems it appropriate. There may be increased risk of injury
to patients if physicians attempt to use our products for uses for which they are not approved. Furthermore, the use of our products for indications other than
those approved by the FDA may not effectively treat such conditions, which could harm our reputation in the marketplace among physicians and patients.

57

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If the FDA determines that our promotional materials or training constitute promotion of an off-label or other improper use, it could request that we modify
our  training  or  promotional  materials,  or  subject  us  to  regulatory  or  enforcement  actions,  including  the  issuance  of  an  untitled  letter,  a  warning  letter,
injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action if they
consider our business activities to constitute promotion of an off-label use, which could result in significant penalties, including, but not limited to, criminal,
civil  or  administrative  penalties,  damages,  fines,  disgorgement,  exclusion  from  participation  in  government  healthcare  programs,  mandatory  compliance
programs under corporate integrity agreements, debarment, refusal of government contracts, and the curtailment of our operations.

These regulations or codes may limit our ability to effectively market our products, or we could run afoul of the requirements imposed by these regulations,
causing reputational harm. These regulations or codes may also impose potentially substantial costs on us.

We may not be able to respond effectively to changing consumer preferences and demand.

Our success depends, in part, on our ability to anticipate and respond to changing consumer trends and preferences in the pharmaceutical industry. We may
not be able to respond to these changes in a timely or commercially effective manner or at all. Our failure to accurately predict these trends could negatively
impact our inventory levels, sales and reputation. The commercial success of our drug products will depend upon a number of factors, including our ability
to, among others:

● anticipate consumers’ therapeutic needs;
● innovate, develop and commercialize new drug products in a timely manner;
● competitively price our drug products;
● procure and maintain our drug products in sufficient volumes and in a timely manner; and
● differentiate our drug products from those of our competitors.

If we are unable to introduce new drug products, develop improvements to our existing drug products or maintain the appropriate inventory levels to meet
our customers’ demand in a timely manner or at all, our business and prospects could be materially and adversely affected.

We may be exposed to claims and may not be able to obtain or maintain adequate product liability insurance.

Our  business  is  exposed  to  the  risk  of  product  liability  and  other  liability  risks  that  are  inherent  in  the  development,  manufacture,  clinical  testing  and
marketing of pharmaceutical products. These risks exist even if a product is approved for commercial sale by the FDA or comparable regulatory authorities
in  other  countries  and  manufactured  in  licensed  facilities.  Our  current  product  candidates,  LIQ861  and  LIQ865,  are  designed  to  affect  important  bodily
functions and processes. Any side effects, manufacturing defects, misuse or abuse associated with our products could result in injury to a patient or even
death.

Claims that are successfully brought against us could have a material and adverse effect on our financial condition and results of operations. Further, even if
we are successful in defending claims brought against us, our reputation could suffer. Regardless of merit or eventual outcome, product liability claims may
also result in, among others:

● a decreased demand for our products;
● a withdrawal or recall of our products from the market;

58

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● a withdrawal of participants from our ongoing clinical trials;
● the distraction of our management’s attention from our core business activities to defend such claims;
● additional costs to us; and
● a loss of revenue.

Our insurance may not provide adequate coverage against our potential liabilities. Furthermore, we, our collaborators or our licensees may not be able to
obtain or maintain insurance on acceptable terms, or at all. In addition, our collaborators or licensees may not be willing to indemnify us against these types
of  liabilities  and  may  not  themselves  be  sufficiently  insured  or  have  sufficient  assets  to  satisfy  any  product  liability  claims.  To  the  extent  that  they  are
uninsured  or  uninsurable,  claims  or  losses  that  may  be  suffered  by  us,  our  collaborators  or  our  licensees  may  have  a  material  and  adverse  effect  on  our
financial condition and results of operations.

If  our  product  candidates  are  approved  for  commercialization  outside  of  the  United  States,  we  may  be  exposed  to  a  number  of  risks  associated  with
international business operations.

If our product candidates are approved for commercialization outside of the United States, we may market our drug products ourselves, or we may enter into
agreements  with  third  parties  to  market  the  aforesaid  drug  products  outside  of  the  United  States.  In  such  event,  we  may  be  subject  to  risks  related  to
international business operations, including, but not limited to:

● varying levels of protection for intellectual property rights;
● changes in tariffs and the imposition of trade barriers;
● economic weakness, including inflation or political instability in particular foreign economies and markets;
● differing payor reimbursement regimes, governmental payors or patient self-pay systems and price controls;
● compliance with tax, employment, immigration and labor laws in respect of employees living or traveling abroad;
● foreign tax laws;
● currency fluctuations; and
● business interruptions resulting from geopolitical actions, such as wars and terrorist attacks, among others, or global pandemics or natural disasters,

such as fires, floods, earthquakes and hurricanes, among others.

Risks Related to the Development and Regulatory Approval of our Product Candidates

We are primarily dependent on the success of our lead product candidate, LIQ861, for which we have recently filed an NDA with the FDA, and to a
lesser  degree,  LIQ865,  which  is  still  in  clinical  development,  and  these  product  candidates  may  fail  to  receive  marketing  approval  or  may  not  be
commercialized successfully.

We  do  not  have  any  products  approved  for  marketing  in  any  jurisdiction  and  we  have  never  generated  any  revenue  from  product  sales.  Our  ability  to
generate revenue from product sales and achieve profitability depends on our ability, alone or with strategic collaboration partners, to successfully complete
the development of, and obtain the regulatory and marketing approvals necessary to commercialize, one or more of our product candidates. We expect that a
substantial  portion  of  our  efforts  and  expenditure  over  the  next  few  years  will  be  devoted  to  our  product  candidates,  LIQ861,  a  proprietary  inhaled  dry
powder  formulation  of  treprostinil  for  the  treatment  of  pulmonary  arterial  hypertension,  or  PAH,  and  LIQ865,  a  sustained-release  formulation  of
bupivacaine for the management of local post-operative pain. We do not anticipate generating revenue from product sales until 2021 at the earliest, if ever.

LIQ861  is  being  developed  under  the  505(b)(2)  regulatory  pathway  with  Tyvaso  as  the  reference  listed  drug.  We  commenced  a  Phase  3  clinical  trial  of
LIQ861, which we refer to as INSPIRE, in the first quarter of 2018 and reported completion of enrollment and achievement of the primary endpoint, which
was  long-term  safety  and  tolerability,  in  the  first  quarter  of  2019.  LIQ861  was  observed  to  be  well-tolerated  in  109  patients,  with  101  patients  (93%)
completing at least two months of treatment. During the two-month treatment period, LIQ861 was evaluated at doses up to 159 mcg with no study-drug
related serious adverse events, with some patients receiving doses up to 212 mcg after the two-month timepoint. Exploratory endpoints of the INSPIRE trial
demonstrated generally favorable functional and patient outcomes.

59

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In  June  2019,  we  reported  results  from  the  INSPIRE  study  indicating  that  the  79.5  mcg  dose  of  LIQ861  correlates  with  nine  breaths  of  Tyvaso,  the
maximum recommended label dose of Tyvaso. Analysis of the data from the PK sub-study in patients showed variability in systemic plasma levels of both
LIQ861 and Tyvaso, which is believed to be attributed to variation in severity of disease and has been seen in prior studies of treprostinil in patients. To
more accurately characterize the PK of LIQ861, we conducted two additional PK studies in healthy volunteers. In the first of these studies, we observed
unexpected variability in PK levels. Post-hoc analysis showed that plasma levels of treprostinil were tightly correlated to the LIQ861 dose delivered. Based
upon  additional  non-clinical  and  clinical  work,  we  believe  the  unexpected  variability  seen  in  this  healthy  volunteer  study  was  due  to  an  administration
technique unique to the conduct of the study in the Phase 1 setting. In August 2019, we completed a second PK study in healthy volunteers in which the
proper administration technique was followed. This study demonstrated significantly reduced variability, and we believe we have established comparative
bioavailability to the reference listed drug.

In  August  2019,  one  of  the  clinical  investigators  in  the  INSPIRE  study  reassessed  a  serious  adverse  event,  preliminarily  identified  as  hypersensitivity
pneumonitis, as being possibly related to LIQ861, whereas the investigator had previously, in May and June 2019, characterized the event as not related to
LIQ861. Based on the patient’s medical history, two other potential alternative causes of this event noted by the clinical investigator, and the fact that the
patient  has  been  taking  LIQ861  since  October  2018,  we  do  not  agree  with  the  clinical  investigator’s  assessment.  However,  we  reported  the  event  to  the
FDA, as required, and we will continue to monitor and assess this event for any change.

We  completed  the  pivotal  INSPIRE  trial  in  October  2019  and  submitted  an  NDA  for  LIQ861  to  the  FDA  in  January  2020.  Final  enrollment  in  the  trial
included 121 PAH patients to assess safety and tolerability through Month 2, the primary endpoint of the trial. Of the 121 patients enrolled in the study, 55
were Transition patients and 66 were Add-On patients. Add-On patients started on a dose of 26.5 mcg of LIQ861, with most (>80%) titrating to a 79.5 mcg
dose or higher within the first two months of treatment. Consistent with preliminary data presented in the second quarter of 2019, LIQ861 was observed to
be well-tolerated and treatment-emergent adverse events were mostly mild to moderate in nature at Month 2 up to doses of 159 mcg of LIQ861, the highest
dose  studied  at  Month  2.  Durability  of  therapy  with  LIQ861  appeared  to  be  favorable,  with  96%  of  Transition  patients  and  91%  of  Add-On  patients
remaining on study drug at the Month 2 timepoint.

Initial  analysis  of  the  exploratory  endpoints  from  the  INSPIRE  study  indicates  that  LIQ861  may  provide  functional  and  quality-of-life  benefits  to  PAH
patients in New York Heart Association, or NYHA, functional classes II and III. More than 90% of all patients who completed two months of treatment
maintained or improved their NYHA functional class. Additionally, we observed improvement in six-minute-walk-distance and quality of life as measured
by the MLHFQ in both patient groups.

We continued to treat patients who chose to remain on LIQ861 beyond the Month 2 timepoint of the primary endpoint. More than 80% of INSPIRE patients
remained on study drug at Month 4 with no significant changes in safety or tolerability observed compared to Month 2. At the completion of the INSPIRE
study, the patient with the longest duration of treatment had been on LIQ861 therapy for 18 months. To provide for continuity of treatment, patients from
INSPIRE were provided the opportunity to continue receiving treatment in an extension study, which is currently ongoing. In addition, we are enrolling
patients in a clinical study at certain investigational sites in Europe to characterize the hemodynamic dose-response relationship to LIQ861. We are also
considering conducting other clinical trials to generate additional data on LIQ861, including a clinical trial in pediatric patients. We also continue to conduct
development work in support of potential approval and commercialization of LIQ861, including label and patient-use assessments.

With respect to LIQ865, we initiated Phase 2-enabling toxicology studies in March 2019 in both soft tissue and bone models. The soft tissue toxicology
study showed favorable results. However, our bone toxicology study showed delayed bone healing at the dose tested and we therefore have recently initiated
an additional non-GLP bone toxicology study at lower doses of LIQ865, with results expected during the second half of 2020. Provided that results of this
study are favorable, we may then initiate a GLP bone toxicology study. We may also consider developing one or more alternative formulations of LIQ865.
Depending upon the results of the further bone toxicology studies and the availability of funding, among other considerations, we may initiate one or more
Phase 2 proof-of-concept clinical trials during 2021. We cannot assure you that our toxicology studies or clinical trials, if commenced, will be successful or
meet their endpoints, or that the endpoints for any future Phase 3 trials that we may conduct will be sufficient to receive marketing approval.

60

 
 
 
 
 
 
 
 
If we successfully complete the clinical development of LIQ861 and LIQ865, we cannot assure you that they will receive marketing approval. The FDA or
comparable regulatory authorities in other countries may delay, limit or deny approval of our product candidates for various reasons. For example, such
authorities may disagree with the design, scope or implementation of our clinical trials, or with our interpretation of data from our preclinical studies or
clinical trials. Further, there are numerous FDA personnel assigned to review different aspects of an NDA, and uncertainties can be presented by their ability
to exercise judgment and discretion during the review process. During the course of review, the FDA may request or require additional preclinical, clinical,
CMC  (chemistry,  manufacturing,  and  control),  or  other  data  and  information,  and  the  development  and  information  may  be  time-consuming  and
expensive. Status as a combination product, as is the case for LIQ861, may complicate or delay the FDA review process. Product candidates that the FDA
deems to be combination products, such as LIQ861, or that otherwise rely on innovative drug delivery systems, may face additional challenges, risks and
delays in the product development and regulatory approval process. Moreover, the applicable requirements for approval may differ from country to country.

If  we  successfully  obtain  marketing  approval  for  LIQ861  and  LIQ865,  we  cannot  assure  you  that  they  will  be  commercialized  in  a  timely  manner  or
successfully, or at all. For example, LIQ861 and LIQ865 may not achieve a sufficient level of market acceptance, or we may not be able to effectively build
our marketing and sales capabilities or scale our manufacturing operations to meet commercial demand. The successful commercialization of LIQ861 and
LIQ865 will also, in part, depend on factors that are beyond our control. Therefore, we may not generate significant revenue from the sale of such products,
even if approved. Any delay or setback we face in the commercialization of LIQ861 or LIQ865 may have a material and adverse effect on our business and
prospects, which will adversely affect your investment in our company.

Our preclinical studies and clinical trials may not be successful and delays in such preclinical studies or clinical trials may cause our costs to increase
and significantly impair our ability to commercialize our product candidates. Results of previous clinical trials or interim results of ongoing clinical
trials may not be predictive of future results.

Before we are able to commercialize our drug products, we are required to undertake extensive preclinical studies and clinical trials to demonstrate that our
drug products are safe and effective for their intended uses. However, we cannot assure you that our drug products will, in preclinical studies and clinical
trials, demonstrate safety and efficacy as necessary to obtain marketing approval. Due to the nature of drug product development, many product candidates,
especially those in early stages of development, may be terminated during development. Although we believe we have completed clinical development for
LIQ861, we have not yet obtained approval for or commercialized any product candidates and as a result do not have a track record of successfully bringing
product candidates to market. Furthermore, LIQ861 and LIQ865 have, to date, been tested only in relatively small study populations and, accordingly, the
results from our earlier clinical trials may be less reliable than results achieved in larger clinical trials. Additionally, the outcome of preclinical testing and
early clinical trials may not be predictive of the success of later clinical trials, and preliminary and interim results of a clinical trial do not necessarily predict
final results.

Preclinical  studies  and  clinical  trials  may  fail  due  to  factors  such  as  flaws  in  trial  design,  dose  selection  and  patient  enrollment  criteria.  The  results  of
preclinical studies and early clinical trials may not be indicative of the results of subsequent clinical trials. Product candidates may, in later stages of clinical
testing, fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and earlier clinical trials. Moreover, there
may be significant variability in safety or efficacy results between different trials of the same product candidate due to factors including, but not limited to,
changes  in  trial  protocols,  differences  in  the  composition  of  the  patient  population,  adherence  to  the  dosing  regimen  and  other  trial  protocols  and
amendments to protocols and the rate of drop-out among patients in a clinical trial. If our preclinical studies or clinical trials are not successful and we are
unable to bring our product candidates to market as a result, our business and prospects may be materially and adversely affected.

61

 
 
 
 
 
 
 
Furthermore, conducting preclinical studies and clinical trials is a costly and time-consuming process. The length of time required to conduct the required
studies and trials may vary substantially according to the type, complexity, novelty and intended use of the product candidate. A single clinical trial may
take up to several years to complete. Moreover, our preclinical studies and clinical trials may be delayed or halted due to various factors, including, among
others:

● delays in raising the funding necessary to initiate or continue a clinical trial;
● delays in manufacturing sufficient quantities of product candidates for clinical trials;
● delays in reaching agreement on acceptable terms with prospective contract research organizations and clinical trial sites;
● delays in obtaining institutional review board approval at clinical trial sites;
● delays in recruiting suitable patients to participate in a clinical trial;
● delays in patients’ completion of clinical trials or their post-treatment follow-up;
● regulatory authorities’ interpretation of our preclinical and clinical data; and
● unforeseen  safety  issues,  including  a  high  and  unacceptable  severity,  or  prevalence,  of  undesirable  side  effects  or  adverse  events  caused  by  our

product candidates or similar drug products or product candidates.

If  our  preclinical  studies  or  clinical  trials  are  delayed,  the  commercialization  of  our  product  candidates  will  be  delayed  and,  as  a  result,  we  may  incur
substantial additional costs or not be able to recoup our investment in the development of our product candidates, which would have a material and adverse
effect on our business.

LIQ861, for which we recently submitted an NDA, requires regulatory review, and, subject to feedback from the FDA, may require additional clinical
testing  and  data  analysis.  LIQ865,  for  which  we  have  only  completed  a  single  Phase  1  study,  requires  additional  clinical  testing,  data  analysis,  and
regulatory review. Clinical trials and data analysis can be expensive, time-consuming and difficult to design and implement. If we are unsuccessful in
obtaining regulatory approval for LIQ861 or LIQ865, or any of our product candidates do not provide positive results, we may be required to delay or
abandon development of such product, which would have a material adverse impact on our business.

Continuing  product  development  requires  additional  and  extensive  clinical  testing.  Human  clinical  trials  are  very  expensive  and  difficult  to  design  and
implement, in part because they are subject to rigorous regulatory requirements. The clinical trial process is also time-consuming. We cannot provide any
assurance  or  certainty  regarding  when  we  might  receive  regulatory  approval  for  LIQ861  or  LIQ865.  Furthermore,  failure  can  occur  at  any  stage  of  the
process,  and  we  could  encounter  problems  that  cause  us  to  abandon  an  NDA  filed  with  the  FDA  or  repeat  clinical  trials.  The  commencement  and
completion of clinical trials for any current or future development product candidate may be delayed by several factors, including:

● unforeseen safety issues;
● determination of dosing issues;
● lack of effectiveness during clinical trials;
● slower than expected rates of patient recruitment;
● inability to monitor patients adequately during or after treatment; and
● inability or unwillingness of medical investigators to follow our clinical protocols or amendments to our protocols.

In addition, the FDA or an independent institutional review board, or IRB, may suspend our clinical trials at any time if it appears that we are exposing
participants to unacceptable health risks or if the FDA finds deficiencies in our IND submissions or the conduct of these trials. Therefore, we cannot provide
any assurance or predict with certainty the schedule for future clinical trials. In the event we do not ultimately receive regulatory approval for LIQ861 and
LIQ865, we may be required to terminate development of our only product candidates.

The marketing approval processes of the FDA and comparable regulatory authorities in other countries are unpredictable and our product candidates
may be subject to multiple rounds of review or may not receive marketing approval.

We  have  not  previously  submitted  an  NDA  to  the  FDA  or  similar  drug  approval  filings  to  comparable  regulatory  authorities  in  other  countries  for  any
product  candidate,  and  we  cannot  assure  you  that  any  of  our  product  candidates  will  receive  marketing  approval.  Filing  an  application  and  obtaining
marketing approval for a pharmaceutical product candidate is an extensive, lengthy, expensive and inherently uncertain process, and regulatory authorities
may delay, limit or deny approval of our product candidates for many reasons, including, but not limited to, the following:

● the  FDA  or  comparable  regulatory  authorities  in  other  countries  may  refuse  to  file  an  NDA  or  similar  drug  approval  filing  if  they  deem  the

application to be incomplete;

● the FDA or comparable regulatory authorities in other countries may disagree with the number, design, size, conduct or statistical analysis of one

or more of our clinical trials;

● we may be unable to demonstrate to the satisfaction of the FDA or comparable regulatory authorities in other countries that our product candidate

is safe and effective for its proposed indication, or that its clinical and other benefits outweigh its safety risks;

● the results of our clinical trials may not meet the level of statistical significance required by the FDA or comparable regulatory authorities in other

countries;

● the data collected from our clinical trials may not be sufficient to support the submission of an NDA or similar drug approval filing to the FDA or

comparable regulatory authorities in other countries;

● the FDA or comparable regulatory authorities in other countries may disagree with our interpretation of data from our preclinical studies or clinical

trials;

● our  manufacturing  processes  and  facilities  have  not  been  inspected  by  the  FDA,  and  the  FDA  or  comparable  regulatory  authorities  in  other
countries  may  not  ultimately  conclude  that  our  manufacturing  processes  or  facilities  or  those  of  our  third-party  manufacturers  sufficiently
demonstrate compliance with cGMP to support NDA approval;

● our product candidates may not meet the level of quality and control required by the FDA or comparable regulatory authorities in other countries;
● our product candidates may not demonstrate sufficient long-term stability to support an NDA filing or obtain approval, or the product shelf life

may be limited by stability results;

● the FDA or comparable regulatory authorities in other countries may require development of a costly and extensive risk evaluation and mitigation

strategy, or REMS, as a condition of approval;

● the success or further approval of competing products approved in indications similar to those of our product candidates may change the standards

for approval of our product candidates in their proposed indications; and

● the  approval  policies  of  the  FDA  or  comparable  regulatory  authorities  in  other  countries  may  change  in  a  manner  that  renders  our  clinical  data

insufficient for approval.

In  addition,  the  FDA  or  comparable  regulatory  authorities  in  other  countries  may,  in  their  sole  discretion,  change  their  views  in  respect  of  regulatory
pathways they had previously affirmed or clinical trial protocols to which they were previously not opposed. While we have consulted with the FDA on the
appropriate regulatory pathway and clinical trial protocols for our product candidates, LIQ861 and LIQ865, we cannot assure you that the FDA will not
revise its position significantly at a later date. In the event that this occurs, the clinical development and commercialization of our product candidates may
be delayed or even derailed.

Even if we obtain marketing approval, the FDA or comparable regulatory authorities in other countries may approve our product candidates for fewer or
more limited indications than those for which we requested approval, or may include safety warnings or other restrictions that may negatively impact the
commercial viability of our product candidates. Likewise, regulatory authorities may grant approval contingent on the performance of costly post-marketing
clinical  trials  or  the  conduct  of  an  expensive  REMS,  which  could  significantly  reduce  the  potential  for  commercial  success  or  viability  of  our  product
candidates. We also may not be able to find acceptable collaborators to manufacture our drug products, if and when approved, in commercial quantities and
at acceptable prices, or at all.

63

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our  product  candidates  may  cause  undesirable  side  effects  or  have  other  properties  that  could  delay  or  prevent  their  regulatory  approval,  limit  the
commercial potential or result in significant negative consequences following any potential marketing approval.

If our product candidates are associated with undesirable side effects or have characteristics that are unexpected, we may need to abandon our development
or limit development to certain uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more
acceptable  from  a  risk-benefit  perspective.  Any  serious  adverse  or  undesirable  side  effects  identified  during  the  development  of  our  product  candidates
could interrupt, delay or halt clinical trials and could result in the denial of regulatory approval by the FDA or other regulatory authorities for any or all
targeted indications, and in turn prevent us from commercializing our product candidates and generating revenues from their sale. In addition, if any of our
product candidates receive regulatory approval and we or others later identify undesirable adverse effects caused by the product, we could face one or more
of the following consequences:

● regulatory  authorities  may  require  the  addition  of  labeling  statements,  such  as  a  boxed  warning  or  a  contraindication,  or  other  safety  labeling

changes;

● regulatory authorities may require a REMS;
● regulatory authorities may withdraw their approval of the product;
● regulatory authorities may seize the product;
● we may be required to change the way that the product is administered;
● we may be required to conduct additional clinical trials;
● we may be required to recall the product;
● we may be subject to litigation or product liability claims, fines, injunctions or criminal penalties; and
● our reputation may suffer.

We may encounter difficulties in enrolling patients in our clinical trials.

We may not be able to commence or complete clinical trials for our product candidates if we are unable to locate and enroll a sufficient number of eligible
patients to participate in these trials.

Patient enrollment may be affected by, among others:

● the severity of the disease under investigation;
● the design of the clinical trial protocol and amendments to a protocol;
● the size and nature of the patient population;
● eligibility criteria for the clinical trial in question;
● the  perceived  risks  and  benefits  of  the  product  candidate  under  clinical  testing,  including  a  high  and  unacceptable  severity,  or  prevalence,  of

undesirable side effects or adverse events caused by our product candidates or similar products or product candidates;

● the existing body of safety and efficacy data in respect of the product candidate under clinical testing;
● the proximity of patients to clinical trial sites; and
● the number and nature of competing therapies and clinical trials.

Any negative results we may report in clinical trials of our product candidates may also make it difficult or impossible to recruit and retain patients in other
clinical trials of that same product candidate.

In particular, we will be required to identify and enroll a sufficient number of patients with PAH for our clinical trials and studies of LIQ861. PAH is a rare
disease with a relatively small patient population, and our enrollment of clinical trial participants may be slow as a result. Additionally, we expect that if we
initiate, as we are currently contemplating, a clinical trial of LIQ861 in pediatric patients, we may encounter difficulties enrolling patients in such a trial
because of the limited number of pediatric patients with this disease. Furthermore, we are aware of a number of therapies for PAH that are being developed
or that are already available on the market, and we expect to face competition from these investigational drugs or approved drugs for potential subjects in
our clinical trials, which may delay enrollment in our planned clinical trials.

64

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Delays or failures in planned patient enrollment or retention may result in increased costs, program delays, or both. We may, as a result of such delays or
failures,  be  unable  to  carry  out  our  clinical  trials  as  planned  or  within  the  timeframe  that  we  expect  or  at  all,  and  our  business  and  prospects  may  be
materially and adversely affected as a result.

Product candidates that the FDA deems to be combination products, such as LIQ861, or that otherwise rely on innovative drug delivery systems, may
face additional challenges, risks and delays in the product development and regulatory approval process.

The FDA has indicated that it considers LIQ861, which is delivered by a DPI, to be a drug-device combination product and, accordingly, the DPI will be
evaluated  as  part  of  our  NDA  filing.  When  evaluating  products  that  utilize  a  specific  drug  delivery  system  or  device,  the  FDA  will  evaluate  the
characteristics of that delivery system and its functionality, as well as the potential for undesirable interactions between the drug and the delivery system,
including  the  potential  to  negatively  impact  the  safety  or  effectiveness  of  the  drug.  The  FDA  review  process  can  be  more  complicated  for  combination
products,  and  may  result  in  delays,  particularly  if  novel  delivery  systems  are  involved.  We  rely  on  third  parties  for  the  design  and  manufacture  of  the
delivery  systems  for  our  products,  including  the  DPI  for  LIQ861,  and  in  some  cases  for  the  right  to  refer  to  their  data  on  file  with  the  FDA  or  other
regulators. Quality or design concerns with the delivery system, or commercial disputes with these third parties, could delay or prevent regulatory approval
and commercialization of our product candidates.

We are planning to pursue the FDA 505(b)(2) pathway for all of our current product candidates. If we are unable to rely on the 505(b)(2) regulatory
pathway  to  apply  for  marketing  approval  of  our  product  candidates  in  the  United  States,  seeking  approval  of  these  product  candidates  through  the
505(b)(1) NDA pathway would require full reports of investigations of safety and effectiveness, and the process of obtaining marketing approval for our
product candidates would likely be significantly longer and more costly.

We are currently focused on developing drug products that can be approved under abbreviated regulatory pathways in the United States, such as the 505(b)
(2) regulatory pathway, which permits the filing of an NDA where at least some of the information required for approval comes from studies that were not
conducted by or for the applicant and for which the applicant has not obtained a right of reference. Section 505(b)(2), if applicable to us for a particular
product candidate, would allow an NDA we submit to the FDA to rely in part on data in the public domain or the FDA’s prior conclusions regarding the
safety  and  effectiveness  of  approved  compounds,  which  could  expedite  the  development  program  for  a  product  candidate  by  potentially  decreasing  the
amount of clinical data that we would need to generate in order to obtain FDA approval. We plan to pursue this pathway for our current product candidates,
LIQ861 and LIQ865, and have submitted a 505(b)(2) NDA for LIQ861. Even if the FDA allows us to rely on the 505(b)(2) regulatory pathway, we cannot
assure you that such marketing approval will be obtained in a timely manner, or at all.

The FDA may require us to perform additional clinical trials to support any change from the reference listed drug, which could be time-consuming and
substantially delay our receipt of marketing approval. Also, as has been the experience of others in our industry, our competitors may file citizens’ petitions
with the FDA to contest approval of our NDA, which may delay or even prevent the FDA from approving any NDA that we submit under the 505(b)(2)
regulatory  pathway.  If  an  FDA  decision  or  action  relative  to  our  product  candidate,  or  the  FDA’s  interpretation  of  Section  505(b)(2)  more  generally,  is
successfully challenged, it could result in delays or even prevent the FDA from approving a 505(b)(2) application for our product candidates. Even if we are
able  to  utilize  the  505(b)(2)  regulatory  pathway,  a  drug  approved  via  this  pathway  may  be  subject  to  the  same  post-approval  limitations,  conditions  and
requirements as any other drug.

65

 
 
 
 
 
 
 
 
In addition, we may face patent infringement lawsuits in relation to our NDAs submitted under the 505(b)(2) regulatory pathway, which may further delay
or prevent the review or approval of our product candidates. The pharmaceutical industry is highly competitive, and 505(b)(2) NDAs are subject to special
requirements  designed  to  protect  the  patent  rights  of  sponsors  of  previously  approved  drugs  that  are  referenced  in  a  505(b)(2)  NDA.  If  the  previously
approved  drugs  referenced  in  an  applicant’s  505(b)(2)  NDA  are  protected  by  patent(s)  listed  in  the  FDA’s  Approved  Drug  Products  with  Therapeutic
Equivalence Evaluations publication, or the Orange Book, the 505(b)(2) applicant is required to make a claim after filing their its NDA that each such patent
is invalid, unenforceable or will not be infringed. The patent holder may thereafter bring suit for patent infringement, which will trigger a mandatory 30-
month delay (or the shorter of dismissal of the lawsuit or expiration of the patent(s)) in approval of the 505(b)(2) NDA application. It is not uncommon for a
manufacturer of an approved product to file a citizen petition with the FDA seeking to delay approval of, or impose additional approval requirements for,
pending competing products. If successful, such petitions can significantly delay, or even prevent, the approval of the new product. However, even if the
FDA ultimately denies such a petition, the FDA may substantially delay approval while it considers and responds to the petition.

If the FDA determines that our product candidates do not qualify for the 505(b)(2) regulatory pathway, we would need to reconsider our plans and might not
be able to commercialize our product candidates in a cost-efficient manner, or at all. If we were to pursue approval under the 505(b)(1) NDA pathway, we
would  be  subject  to  more  extensive  requirements  and  risks  such  as  conducting  additional  clinical  trials,  providing  additional  data  and  information  or
meeting additional standards for marketing approval. As a result, the time and financial resources required to obtain marketing approval for our product
candidates would likely increase substantially and further complications and risks associated with our product candidates may arise. Also, new competing
products may reach the market faster than ours, which may materially and adversely affect our competitive position, business and prospects.

We may be unable to continually develop a pipeline of product candidates, which could affect our business and prospects.

A key element of our long-term strategy is to continually develop a pipeline of product candidates by developing proprietary innovations to FDA-approved
drug products using our PRINT technology. If we are unable to identify off-patent drug products for which we can develop proprietary innovations using
our  PRINT  technology  or  otherwise  expand  our  product  candidate  pipeline,  whether  through  licensed  or  co-development  opportunities,  and  obtain
marketing  approval  for  such  product  candidates  within  the  timeframes  that  we  anticipate,  or  at  all,  our  business  and  prospects  may  be  materially  and
adversely affected.

We have conducted, and may in the future conduct, clinical trials for our product candidates outside the United States and the FDA may not accept data
from such trials.

Although  the  FDA  may  accept  data  from  clinical  trials  conducted  outside  the  United  States  in  support  of  safety  and  efficacy  claims  for  our  product
candidates, if not conducted under an IND, this is subject to certain conditions set out in 21 C.F.R. § 312.120. For example, in order for the FDA to accept
data  from  such  a  foreign  clinical  trial,  the  study  must  have  been  conducted  in  accordance  with  Good  Clinical  Practice,  or  GCP,  including  review  and
approval by an independent ethics committee and obtaining the informed consent from subjects of the clinical trials. The FDA must also be able to validate
the  data  from  the  study  through  an  onsite  inspection  if  the  agency  deems  it  necessary.  In  addition,  foreign  clinical  data  submitted  to  support  FDA
applications  should  be  applicable  to  the  U.S.  population  and  U.S.  medical  practice.  Other  factors  that  may  affect  the  acceptance  of  foreign  clinical  data
include differences in clinical conditions, study populations or regulatory requirements between the United States and the foreign country.

We  conducted  the  early  Phase  1a  clinical  trial  of  LIQ865  in  Denmark,  and  not  under  an  IND,  we  are  currently  conducting  an  additional  clinical  trial  in
Europe  that  explores  the  hemodynamic  effects  of  LIQ861  in  PAH  patients,  and  we  may,  in  the  future,  conduct  clinical  trials  of  our  product  candidates
outside the United States. The FDA may not accept such foreign clinical data, and in such event, we may be required to re-conduct relevant clinical trials
within the United States, which would be costly and time-consuming, and which could have a material and adverse effect on our ability to carry out our
business plans.

66

 
 
 
 
 
 
 
 
 
Even if we obtain marketing approval for our product candidates in the United States, we or our collaborators may not obtain marketing approval for
the same product candidates elsewhere.

We may enter into strategic collaboration arrangements with third parties to commercialize our product candidates outside of the United States. In order to
market  any  product  candidate  outside  of  the  United  States,  we  or  our  collaborators  will  be  required  to  comply  with  numerous  and  varying  regulatory
requirements  of  other  countries  regarding  safety  and  efficacy.  Clinical  trials  conducted  in  one  country  may  not  be  recognized  or  accepted  by  regulatory
authorities in other countries, and obtaining marketing approval in one country does not mean that marketing approval will be obtained in any other country.
Approval processes vary among countries and additional product testing and validation, or additional administrative review periods, may be required from
one country to the next.

Seeking  marketing  approval  in  countries  other  than  the  United  States  could  be  costly  and  time-consuming,  especially  if  additional  preclinical  studies  or
clinical  trials  are  required  to  be  conducted.  We  currently  do  not  have  any  product  candidates  approved  for  sale  in  any  jurisdiction,  including  non-U.S.
markets, and we do not have experience in obtaining marketing approval in non-U.S. markets. We currently also have not identified any collaborators to
market  our  products  outside  of  the  United  States  and  cannot  assure  you  that  such  collaborators,  even  if  identified,  will  be  able  to  successfully  obtain
marketing approval for our product candidates outside of the United States. If we or our collaborators fail to obtain marketing approval in non-U.S. markets,
or  if  such  approval  is  delayed,  our  target  market  may  be  reduced,  and  our  ability  to  realize  the  full  market  potential  of  our  products  will  be  adversely
affected.

Risks Related to Our Dependence on Third Parties

We  depend  on  third  parties  for  clinical  and  commercial  supplies,  including  single  suppliers  for  the  active  ingredient,  the  device,  encapsulation  and
packaging of LIQ861.

We  depend  on  third-party  suppliers  for  clinical  and  commercial  supplies,  including  the  active  pharmaceutical  ingredients  which  are  used  in  our  product
candidates. These supplies may not always be available to us at the standards we require or on terms acceptable to us, or at all, and we may not be able to
locate alternative suppliers in a timely manner, or at all. If we are unable to obtain necessary clinical or commercial supplies, our manufacturing operations
and clinical trials and the clinical trials of our collaborators may be delayed or disrupted and our business and prospects may be materially and adversely
affected as a result.

For  example,  we  currently  rely  on  a  sole  supplier  for  treprostinil,  the  active  pharmaceutical  ingredient  of  LIQ861,  which  sources  treprostinil  from  a
manufacturer in South Korea. If our supplier is unable to supply treprostinil to us in the quantities we require, or at all, or otherwise defaults on its supply
obligations to us, or if it ceases its relationship with us, we may not be able to obtain alternative supplies of treprostinil from other suppliers on acceptable
terms, in a timely manner, or at all. Furthermore, LIQ861 is administered using the RS00 Model 8 DPI, or dry powder inhaler, which is manufactured by
Plastiape S.p.A., or Plastiape, which is located in Italy. We also rely on a sole supplier for encapsulation and packaging services. We purchase treprostinil,
our DPI supply and encapsulation and packaging services pursuant to purchase orders and do not have long-term contracts with these suppliers. In the event
of any prolonged disruption to our supply of treprostinil, the manufacture and supply of RS00 Model 8 DPI or encapsulation and packaging services, our
ability to develop and commercialize, and the timeline for commercialization of, LIQ861 may be adversely affected.

Additionally, in December 2019, a novel strain of COVID-19, or coronavirus, was reported to have surfaced in Wuhan, China and has become a global
pandemic as of the date of this Annual Report on Form 10-K. The full impact of the coronavirus is unknown and rapidly evolving. Both South Korea, the
country  from  which  our  supplier  sources  treprostinil,  and  Italy,  the  country  in  which  Plastiape  is  headquartered,  have  had  significant  outbreaks  of  this
disease, which, in the case of Italy, has led to a lockdown of the entire country as of the date of this Annual Report on Form 10-K. The extent to which the
coronavirus  impacts  our  ability  to  procure  sufficient  supplies  for  the  development  and  commercialization  of  our  products  and  product  candidates  will
depend on the severity, location and duration of the spread of the coronavirus, and the actions undertaken to contain the coronavirus or treat its effects.

67

 
 
 
 
 
 
 
 
 
 
We rely on third parties to conduct our preclinical studies and clinical trials.

We currently rely on, and plan to continue to rely on, third-party CROs to monitor and manage data for our preclinical studies and clinical trials. However,
we are responsible for ensuring that each of our trials is conducted in accordance with the applicable regulatory standards and our reliance on CROs does
not relieve us of our regulatory responsibilities.

The  CROs  on  which  we  rely  are  required  to  comply  with  FDA  regulations  (and  the  regulations  of  comparable  regulatory  authorities  in  other  countries)
regarding GCP. Regulatory authorities enforce GCP standards through periodic inspections. If any of the CROs on which we rely fail to comply with the
applicable  GCP  standards,  the  clinical  data  generated  in  our  clinical  trials  may  be  deemed  unreliable.  While  we  have  contractual  agreements  with  these
CROs,  we  have  limited  influence  over  their  actual  performance  and  cannot  control  whether  or  not  they  devote  sufficient  time  and  resources  to  our
preclinical studies and clinical trials. A failure to comply with the applicable regulations in the conduct of the preclinical studies and clinical trials for our
product candidates may require us to repeat such studies or trials, which would delay the process of obtaining marketing approval for our product candidates
and have a material and adverse effect on our business and prospects.

Some of our CROs have the ability to terminate their respective agreements with us if, among others, it can be reasonably demonstrated that the safety of
the patients participating in our clinical trials warrants such termination. If any of our agreements with our CROs is terminated, and if we are not able to
enter into agreements with alternative CROs on acceptable terms or in a timely manner, or at all, the clinical development of our product candidates may be
delayed and our development expenses could be increased.

If we are unable to establish or maintain licensing and collaboration arrangements with other pharmaceutical companies on acceptable terms, or at all,
we may not be able to develop and commercialize additional product candidates using our PRINT technology.

We have collaborated, and may consider collaborating, with, among others, pharmaceutical companies to expand the applications for our PRINT technology
through licensing as well as joint product development arrangements. In addition, if we are able to obtain marketing approval for our product candidates
from regulatory authorities, we may enter into strategic relationships with collaborators for the commercialization of such products.

Collaboration and licensing arrangements are complex and time-consuming to negotiate, document, implement and maintain. We may not be successful in
our efforts to establish collaboration or other alternative arrangements should we so choose to enter into such arrangements. In addition, the terms of any
collaboration or other arrangements that we may enter into may not be favorable to us or may restrict our ability to enter into further collaboration or other
arrangements with third parties. For example, collaboration agreements may contain exclusivity arrangements which limit our ability to work with other
pharmaceutical companies to expand the applications for our PRINT technology, as is the case in our collaboration agreement with GSK.

If we are unable to establish licensing and collaboration arrangements or the terms of such agreements we enter into are unfavorable to us or restrict our
ability  to  work  with  other  pharmaceutical  companies,  we  may  not  be  able  to  expand  the  applications  for  our  PRINT  technology  or  commercialize  our
products, if and when approved, and our business and prospects may be materially and adversely affected.

Our collaboration and licensing arrangements may not be successful.

Our collaboration and licensing arrangements, as well as any future collaboration and licensing arrangements that we may enter into, may not be successful.
The success of our collaboration and licensing arrangements will depend heavily on the efforts and activities of our collaborators, which are not within our
control. We may, in the course of our collaboration and licensing arrangements, be subject to numerous risks, including, but not limited to, the following:

● our collaborators may have significant discretion in determining the efforts and resources that they will contribute;
● our  collaborators  may  delay  clinical  trials,  provide  insufficient  funding  for  a  clinical  trial  program,  stop  a  clinical  trial,  abandon  a  product
candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing. For example, in July
2018, GSK notified us of its decision to discontinue development of the inhaled antiviral for viral exacerbations in COPD, part of the GSK
ICO Agreement, after completion of its related Phase 1 clinical trial and we do not believe that GSK is currently advancing any program under
our collaboration;

68

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● our  collaborators  may  independently,  or  in  conjunction  with  others,  develop  products  that  compete  directly  or  indirectly  with  our  product

candidates;

● we may grant exclusive rights to our collaborators that would restrict us from collaborating with others. For example, we are currently subject
to  certain  restrictions  with  regard  to  our  ability  to  enter  into  collaboration  arrangements  for  the  development  of  inhaled  therapeutics  based
upon our PRINT technology with third parties pursuant to our collaboration with GSK;

● our  collaborators  may  not  properly  maintain  or  defend  our  intellectual  property  rights  or  may  use  our  intellectual  property  or  proprietary
information in a way that gives rise to actual or threatened litigation that could jeopardize or invalidate our intellectual property or proprietary
information or expose us to potential liability;

● disputes  may  arise  between  us  and  our  collaborators,  which  may  cause  a  delay  in  or  the  termination  of  our  research,  development  or

commercialization activities;

● our  collaboration  and  licensing  arrangements  may  be  terminated,  and  if  terminated,  may  result  in  our  need  for  additional  capital  to  pursue
further  drug  product  development  or  commercialization.  For  example,  our  development  and  licensing  agreement  with  G&W  Laboratories,
Inc., was mutually terminated in April 2018 and we are currently seeking the termination of our collaboration with GSK;

● our collaborators may own or co-own certain intellectual property arising from our collaboration and licensing arrangements with them, which

may restrict our ability to develop or commercialize such intellectual property; and

● our collaborators may alter the strategic direction of their business or may undergo a change of control or management, which may affect the

success of our collaboration arrangements with them.

Risks Related to Legal Compliance Matters

Even if we obtain regulatory approval for a product candidate, our products and business will remain subject to ongoing regulatory obligations and
review.

If our product candidates are approved, they will be subject to ongoing regulatory requirements for manufacturing, labeling, packaging, storage, drug supply
chain  security  surveillance  and  tracking,  advertising,  promotion,  sampling,  record-keeping,  conduct  of  post-marketing  studies  and  submission  of  safety,
efficacy and other post-market information, including both federal and state requirements in the United States and comparable requirements outside of the
United  States.  Accordingly,  we  and  others  with  whom  we  work  must  continue  to  expend  time,  money  and  effort  in  all  areas  of  regulatory  compliance,
including manufacturing, production and quality control. Any regulatory approvals that we may receive for our product candidates may also be subject to
limitations on the approved indicated uses for which the product may be marketed or to the conditions of approval, or contain requirements for potentially
costly post-marketing testing, including Phase 4 clinical trials, and surveillance to monitor the safety and efficacy of the product candidate. The FDA may
also  require  a  REMS  as  a  condition  of  approval  of  our  product  candidates,  which  could  include  requirements  for  a  medication  guide,  physician
communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk minimization tools.
We will also be required to report certain adverse reactions and production problems, if any, to the FDA or other regulatory agencies and to comply with
requirements concerning advertising and promotion for our products. Promotional communications with respect to prescription drugs are subject to a variety
of legal and regulatory restrictions and must be consistent with the information in the product’s approved label. As such, we may not promote our products
for indications or uses for which they do not have FDA or other regulatory agency approval. The holder of an approved NDA must also submit new or
supplemental applications and obtain FDA approval for certain changes to the approved product, product labeling, or manufacturing process. We could also
be asked to conduct post-marketing clinical studies to verify the safety and efficacy of our product candidates in general or in specific patient subsets. An
unsuccessful post-marketing study or failure to complete such a clinical study could result in the withdrawal of marketing approval. Furthermore, any new
legislation  addressing  drug  safety  issues  could  result  in  delays  in  product  development  or  commercialization  or  increased  costs  to  assure  compliance.
Foreign regulatory authorities impose similar requirements. If a regulatory agency discovers previously unknown problems with a product, such as adverse
events  of  unanticipated  severity  or  frequency,  or  disagrees  with  the  promotion,  marketing  or  labeling  of  a  product,  such  regulatory  agency  may  impose
restrictions  on  that  product  or  us,  including  requiring  withdrawal  of  the  product  from  the  market.  If  we  fail  to  comply  with  applicable  regulatory
requirements, a regulatory agency or enforcement authority may, among other things:

● issue warning letters asserting that we are in violation of the law;

69

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● seek an injunction or impose civil or criminal penalties or monetary fines;
● suspend or withdraw regulatory approval;
● suspend any of our ongoing clinical trials;
● refuse to approve pending applications or supplements to approved applications submitted by us or our strategic partners;
● restrict the marketing or manufacturing of our products;
● seize or detain products, or require a product recall;
● refuse to permit the import or export of our product candidates; or
● refuse to allow us to enter into government contracts.

Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could generate negative
publicity. Any failure to comply with ongoing regulatory requirements may significantly and adversely affect our ability to commercialize and generate
revenue from our product candidates. If regulatory sanctions are applied or if regulatory approval is withdrawn, the value of our company and our operating
results will be adversely affected.

We also cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative or executive action,
either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies,
or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain
profitability, which would adversely affect our business, prospects, financial condition and results of operations.

The terms of approvals, ongoing regulations and post-marketing restrictions for our products may limit how we manufacture and market our products,
which could materially impair our ability to generate revenue.

Once marketing approval has been granted, an approved product and its manufacturer and marketer are subject to ongoing review and extensive regulation.
The  FDA  closely  regulates  the  post-approval  marketing  and  promotion  of  drugs  to  ensure  drugs  are  marketed  only  for  the  approved  indications  and  in
accordance  with  the  provisions  of  the  approved  labeling  and  regulatory  requirements.  The  FDA  imposes  stringent  restrictions  on  manufacturers’
communications regarding off-label use, and if we do not restrict the marketing of our products only to their approved indications, we may be subject to
enforcement action for off-label marketing.

The FDA applies a heightened level of scrutiny to comparative claims when applying its statutory standards for advertising and promotion, including with
regard  to  its  requirement  that  promotional  labeling  be  truthful  and  not  misleading.  Any  claim  of  effectiveness  made  in  prescription  drug  promotion,
including comparative effectiveness, must be supported by substantial evidence or substantial clinical experience.

In addition, making comparative claims may draw concerns from our competitors. Where a company makes a claim in advertising or promotion that its
product is superior to the product of a competitor (or that the competitor’s product is inferior), this creates a risk of a lawsuit by the competitor under federal
and state false advertising or unfair and deceptive trade practices law, and possibly also state libel law. Such a suit may seek injunctive relief against further
advertising, a court order directing corrective advertising, and compensatory and punitive damages where permitted by law.

We, and any potential collaborators we may have in the future, must therefore comply with requirements concerning advertising and promotion for any of
our products for which we or our collaborators obtain marketing approval. Thus, if either of our current product candidates receive marketing approval, the
accompanying label may limit the approved use of our product, which could limit sales of the product.

70

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In  addition,  manufacturers  of  approved  products  and  those  manufacturers’  facilities  are  required  to  comply  with  extensive  FDA  requirements,  such  as
ensuring  that  quality  control  and  manufacturing  procedures  conform  to  cGMP  applicable  to  drug  manufacturers,  which  include  requirements  relating  to
quality control and quality assurance as well as the corresponding maintenance of records and documentation and reporting requirements. We, any contract
manufacturers  we  may  engage  in  the  future,  our  future  collaborators,  licensees  and  their  contract  manufacturers  will  also  be  subject  to  other  regulatory
requirements,  including  submissions  of  safety  and  other  post-marketing  information  and  reports,  registration  and  listing  requirements,  requirements
regarding the distribution of samples to clinicians, recordkeeping and costly post-marketing studies or clinical trials and surveillance to monitor the safety or
efficacy of the product such as the requirement to implement a risk evaluation and mitigation strategy.

Our drug products may be subject to recalls, withdrawals, seizures or other enforcement actions by the FDA or comparable regulatory authorities in
other  countries  if  we  fail  to  comply  with  regulatory  requirements  or  previously  unknown  problems  with  our  drug  products  are  discovered  after  they
reach the market.

The  FDA  or  comparable  regulatory  authorities  in  other  countries  may  withdraw  approval  of  our  drug  products  if  we  fail  to  maintain  compliance  with
regulatory requirements or if problems occur after our drug products reach the market. The discovery of previously unknown problems with a drug product,
including adverse events of unanticipated severity or frequency, problems with manufacturing processes or failure to comply with regulatory requirements,
including  the  requirement  to  promote  a  drug  product  only  for  its  approved  indications  and  in  accordance  with  the  provisions  of  its  approved  label,  may
result in, among others:

● restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;
● warning letters or holds on post-approval clinical trials;
● refusal  of  the  FDA  to  approve  pending  NDAs  or  supplements  to  approved  NDAs  or  comparable  regulatory  authorities  refusing  to  approve  any

pending marketing applications, or suspension or revocation of product approvals;
● product seizure or detention, or refusal to permit the import or export of the product; or
● injunctions or the imposition of civil or criminal penalties.

In  the  event  that  our  drug  products  are  subject  to  recalls,  withdrawals,  seizures  or  other  enforcement  actions  by  the  FDA  or  comparable  regulatory
authorities,  our  reputation  and  demand  for  our  drug  products  could  be  materially  and  adversely  affected.  In  addition,  we  may  incur  significant  and
unexpected expenditures and management attention may be diverted in connection with any such recall, withdrawal, seizure or other enforcement action or
any corrective action required to be taken, which could have a material and adverse impact on our business and financial condition.

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could
have a material adverse effect on our business.

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use,
storage, treatment and disposal of hazardous materials and wastes. From time to time and in the future, our operations may involve the use of hazardous and
flammable materials, including chemicals and biological materials, and may also produce hazardous waste products. Even if we contract with third parties
for the disposal of these materials and waste products, we cannot completely eliminate the risk of contamination or injury resulting from these materials. In
the event of contamination or injury resulting from the use or disposal of our hazardous materials, we could be held liable for any resulting damages, and
any liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties for failure to comply with
such laws and regulations.

71

 
 
 
 
 
 
 
 
 
 
 
 
 
 
We maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of
hazardous  materials,  but  this  insurance  may  not  provide  adequate  coverage  against  potential  liabilities.  However,  we  do  not  maintain  insurance  for
environmental liability or toxic tort claims that may be asserted against us.

In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. Current or future
environmental  laws  and  regulations  may  impair  our  research,  development  or  production  efforts.  In  addition,  failure  to  comply  with  these  laws  and
regulations may result in substantial fines, penalties or other sanctions.

Risks Related to our Intellectual Property

Our commercial success depends largely on our ability to protect our intellectual property.

Our commercial success depends, in large part, on our ability to obtain and maintain patent protection and trade secret protection in the United States and
elsewhere in respect of our product candidates and PRINT technology. If we fail to adequately protect our intellectual property rights, our competitors may
be able to erode, negate or preempt any competitive advantage we may have. To protect our competitive position, we have filed and will continue to file for
patents in the United States and elsewhere in respect of our product candidates and PRINT technology. The process of identifying patentable subject matter
and  filing  a  patent  application  is  expensive  and  time-consuming.  We  cannot  assure  you  that  we  will  be  able  to  file  the  necessary  or  desirable  patent
applications at a reasonable cost, in a timely manner, or at all. Further, since certain patent applications are confidential until patents are issued, third parties
may  have  filed  patent  applications  for  subject  matters  covered  by  our  pending  patent  applications  without  us  being  aware  of  such  applications,  and  our
patent  applications  may  not  have  priority  over  patent  applications  of  others.  In  addition,  we  cannot  assure  you  that  our  pending  patent  applications  will
result  in  patents  being  obtained.  The  standards  that  patent  offices  in  different  jurisdictions  use  to  grant  patents  are  not  always  applied  predictably  or
uniformly and may change from time to time.

Even if we have been or are able to obtain patent protection for our product candidates or PRINT technology, if the scope of such patent protection is not
sufficiently broad, we may not be able to rely on such patent protection to prevent third parties from developing or commercializing product candidates or
technology that may copy our product candidates or technology. The enforceability of patents in the pharmaceutical industry involves complex legal and
scientific questions and can be uncertain. Accordingly, we cannot assure you that third parties will not successfully challenge the validity, enforceability or
scope of our patents. A successful challenge to our patents may lead to generic versions of our drug products being launched before the expiry of our patents
or  otherwise  limit  our  ability  to  stop  others  from  using  or  commercializing  similar  or  identical  products  and  technology.  A  successful  challenge  to  our
patents  may  also  reduce  the  duration  of  the  patent  protection  of  our  drug  products  or  technology.  If  any  of  our  patents  are  narrowed  or  invalidated,  our
business and prospects may be materially and adversely affected. In addition, we cannot assure you that we will be able to detect unauthorized use or take
appropriate,  adequate  and  timely  actions  to  enforce  our  intellectual  property  rights.  If  we  are  unable  to  adequately  protect  our  intellectual  property,  our
business, competitive position and prospects may be materially and adversely affected.

Even if our patents or patent applications are unchallenged, they may not adequately protect our intellectual property or prevent third parties from designing
around our patents or other intellectual property rights. If the patent applications we file or may file do not lead to patents being granted or if the scope of
any of our patent applications is challenged, we may face difficulties in developing our product candidates, companies may be dissuaded from collaborating
with us, and our ability to commercialize our product candidates may be materially and adversely affected. We are unable to predict which of our patent
applications will lead to patents or assure you that any of our patents will not be found invalid or unenforceable or challenged by third parties. The patents
of  others  may  prevent  the  commercialization  of  product  candidates  incorporating  our  technology.  In  addition,  given  the  amount  of  time  required  for  the
development, clinical testing and regulatory review of new product candidates, any patents protecting our product candidates may expire before or shortly
after such product candidates might become approved for commercialization.

72

 
 
 
 
 
 
 
 
 
Moreover, the issuance of a patent is not conclusive as to the inventorship of the patented subject matter, or its scope, validity or enforceability. We cannot
assure  you  that  all  of  the  potentially  relevant  prior  art,  that  is,  any  evidence  that  an  invention  is  already  known,  relating  to  our  patents  and  patent
applications, has been found. If such prior art exists, it may be used to invalidate a patent or may prevent a patent from being issued.

In  addition,  we,  our  collaborators  or  our  licensees  may  fail  to  identify  patentable  aspects  of  inventions  made  in  the  course  of  development  and
commercialization  activities  before  it  is  too  late  to  obtain  patent  protection  on  them.  As  a  result,  we  may  miss  potential  opportunities  to  seek  patent
protection or strengthen our patent position.

If we are unable to protect our trade secrets, the value of our PRINT technology and product candidates may be negatively impacted, which would have
a material and adverse effect on our competitive position and prospects.

In addition to patent protection, we rely on trade secret protection to protect certain aspects of our intellectual property. While we require parties who have
access to any portion of our trade secrets, such as our employees, consultants, advisers, CROs, CMOs, collaborators and other third parties, to enter into
non-disclosure and confidentiality agreements with us, we cannot assure you that these parties will not disclose our proprietary information, including our
trade secrets, in breach of their contractual obligations. Enforcing a claim that a party has illegally disclosed or misappropriated a trade secret is difficult,
costly and time-consuming, and we may not be successful in doing so. If the steps we have taken to protect our trade secrets are deemed by the adjudicating
court to be inadequate, we may not be able to obtain adequate recourse against a party for misappropriating our trade secrets.

Trade secrets can be difficult to protect as they may, over time, be independently discovered by our competitors or otherwise become known despite our
trade secret protection. If any of our trade secrets were to be lawfully obtained or independently developed by our competitors, we would have no right to
prevent such competitors, or those to whom they communicate such technology or information, from using that technology or information to compete with
us. Such competitors could attempt to replicate some or all of the competitive advantages we derive from our development efforts, willfully infringe our
intellectual  property  rights,  design  around  our  protected  technology  or  develop  their  own  competitive  technologies  that  fall  outside  of  our  intellectual
property rights.

If our trade secrets were to be disclosed to or independently developed by our competitors, our competitors may be able to exploit our PRINT technology to
develop competing product candidates, and the value of our PRINT technology and our product candidates may be negatively impacted. This would have a
material and adverse effect on our competitive position and prospects.

We rely on licenses to intellectual property that are owned by third parties.

We  have  entered  and  may,  in  the  future,  enter  into  license  agreements  with  third  parties  to  license  the  rights  to  use  their  technologies  in  our  research,
development  and  commercialization  activities.  License  agreements  generally  impose  various  diligence,  milestone  payments,  royalty,  insurance  and  other
obligations on us, and if we fail to comply with these obligations, our licensors may have the right to terminate these license agreements. Termination of
these  license  agreements  or  the  reduction  or  elimination  of  our  licensed  rights  or  the  exclusivity  of  our  licensed  rights  may  have  an  adverse  impact  on,
among others, our ability to develop and commercialize our product candidates. We cannot assure you that we will be able to negotiate new or reinstated
licenses on commercially acceptable terms, or at all.

In  addition,  we  license  certain  patent  rights  for  our  PRINT  technology  from  The  University  of  North  Carolina  at  Chapel  Hill,  or  UNC,  under  the  UNC
Amended and Restated License Agreement, dated as of December 15, 2008, as amended, or the UNC license. Under the UNC License, UNC has the right to
terminate our license if we materially breach the agreement and fail to cure such breach within the stipulated time. In the event that UNC terminates our
license and we have a product that relies on that license, it may bring a claim against us, and if they are successful, we may be required to compensate UNC
for the unauthorized use of their patent rights through the payment of royalties.

73

 
 
 
 
 
 
 
 
 
 
 
Also, the agreements under which we license patent rights may not give us control over patent prosecution or maintenance, so that we may not be able to
control which claims or arguments are presented and may not be able to secure, maintain or successfully enforce necessary or desirable patent protection
from those patent rights. We do not have primary control over patent prosecution and maintenance for certain of the patents we license, and therefore cannot
assure you that these patents and applications will be prosecuted or maintained in a manner consistent with the best interests of our business. We also cannot
assure you that patent prosecution and maintenance activities by our licensors, if any, will be conducted in compliance with applicable laws and regulations
or will result in valid and enforceable patents.

Pursuant to the terms of some of our license agreements with third parties, some of our third-party licensors have the right, but not the obligation, in certain
circumstances, to control the enforcement of our licensed patents or defense of any claims asserting the invalidity of these patents. Even if we are permitted
to pursue such enforcement or defense, we will require the cooperation of our licensors, and we cannot assure you that we will receive such cooperation on
commercially acceptable terms, or at all. We also cannot assure you that our licensors will allocate sufficient resources or prioritize their or our enforcement
of these patents or defense of these claims to protect our interests in the licensed patents. If we cannot obtain patent protection, or enforce existing or future
patents against third parties, our competitive position, business and prospects may be materially and adversely affected.

Further, licenses to intellectual property may not always be available to us on commercially acceptable terms, or at all. In the event that the licenses we rely
on are not available to us on commercially acceptable terms, or at all, our ability to commercialize our PRINT technology or product candidates, and our
business and prospects, may be materially and adversely affected.

We may become involved in litigation to protect our intellectual property or enforce our intellectual property rights, which could be expensive, time-
consuming and may not be successful.

Competitors may infringe our patents or misappropriate or otherwise violate our intellectual property rights. To counter infringement or unauthorized use,
we may engage in litigation to, among others, enforce or defend our intellectual property rights, determine the validity or scope of our intellectual property
rights and those of third parties, and protect our trade secrets. Such actions may be time-consuming and costly and may divert our management’s attention
from our core business and reduce the resources available for our clinical development, manufacturing and marketing activities, and consequently have a
material and adverse effect on our business and prospects, regardless of the outcome.

In addition, in an infringement proceeding, a court may decide that a patent owned by, or licensed to, us is invalid or unenforceable, or may refuse to stop
the  other  party  from  using  the  technology  in  question  on  the  ground  that  our  patents  do  not  cover  such  technology.  An  adverse  result  in  any  litigation
proceeding  could  put  one  or  more  of  our  patents  at  risk  of  being  invalidated,  held  unenforceable  or  interpreted  narrowly.  Furthermore,  because  of  the
substantial  amount  of  discovery  required  in  connection  with  intellectual  property  litigation,  there  is  a  risk  that  our  confidential  information  may  be
compromised by disclosure.

74

 
 
 
 
 
 
 
 
We may be subject to claims that our employees or consultants have wrongfully used or disclosed to us alleged trade secrets of their former employers or
other clients.

As is common in our industry, a number of our employees, including our Chief Executive Officer and a number of our executive officers, were formerly
employed by other biotechnology or pharmaceutical companies, including our competitors or potential competitors, among others, and may have entered
into proprietary rights, non-disclosure and non-competition agreements or similar agreements, in connection with such previous employment. Moreover, we
engage the services of scientific advisers and consultants to assist us in the development of our products, many of whom were previously employed at or
may have previously been or are currently providing consulting or advisory services to, other biotechnology or pharmaceutical companies, and who may
have also entered into proprietary rights, non-disclosure and non-competition (or similar) agreements with such other companies.

While we require that our employees, scientific advisers and consultants do not use the proprietary information or know-how of others in their work for us,
we cannot assure you that we will not be subject to claims that we or these employees, scientific advisers or consultants have inadvertently or otherwise
used or disclosed the trade secrets or proprietary information of their former employers or former or present clients in their work for us, especially where
such  former  employers  or  former  or  present  clients  are  our  competitors  or  potential  competitors.  Claims  brought  against  us  could  cause  us  to  incur
unexpected and substantial costs, as well as divert our management’s attention from our core business and reduce the resources available for our clinical
development, manufacturing and marketing activities. Consequently, our business may be materially and adversely affected.

We may be subject to claims from third parties that our products infringe their intellectual property rights.

The pharmaceutical industry has experienced rapid technological change and obsolescence in the past, and our competitors have strong incentives to stop or
delay any introduction of new drug products or related technologies by, among others, establishing intellectual property rights over their drug products or
technologies and aggressively enforcing these rights against potential new entrants into the market. We expect that we and other industry participants will be
increasingly subject to infringement claims as the number of competitors and drug products grows.

Our commercial success depends in large part upon our ability to develop, manufacture, market and sell our drug products or product candidates without
infringing on the patents or other proprietary rights of third parties. It is not always clear to industry participants, including us, what the scope of a patent
covers. Due to the large number of patents in issue and patent applications filed in our industry, there is a risk that third parties will claim that our products
or technologies infringe their intellectual property rights.

Claims for infringement of intellectual property which are brought against us, whether with or without merit, and which are generally uninsurable, could
result in time-consuming and costly litigation, diverting our management’s attention from our core business and reducing the resources available for our
drug  product  development,  manufacturing  and  marketing  activities,  and  consequently  have  a  material  and  adverse  effect  on  our  business  and  prospects,
regardless of the outcome. Moreover, such proceedings could put our patents at risk of being invalidated or interpreted narrowly and our patent applications
at  risk  of  not  being  issued.  We  also  may  not  prevail  in  any  lawsuits  that  we  initiate  and  the  damages  or  other  remedies  awarded,  if  any,  may  not  be
commercially  meaningful.  Uncertainties  resulting  from  the  initiation  and  continuation  of  litigation  or  other  proceedings  could  also  have  a  material  and
adverse effect on our ability to compete in the market. Third parties making claims against us could obtain injunctive or other equitable relief against us,
which could prevent us from further developing or commercializing our product candidates.

In particular, we may be required to include a certification of patent invalidity or non-infringement, or a paragraph IV certification, in an NDA submitted
under  the  505(b)(2)  regulatory  pathway,  to  certify  that  a  patent  over  a  reference  listed  drug  is  invalid,  unenforceable  or  will  not  be  infringed  by  the
manufacture, use or sale of our product candidate. The holder of such patent may file a patent infringement lawsuit against us after receiving notice of the
paragraph IV certification. Any such patent infringement lawsuit, if filed, will trigger a one-time, automatic, 30-month stay of the FDA’s ability to approve
our application, unless the patent litigation is resolved in our favor or the patent expires before that time. Accordingly, we may invest a significant amount
of time and expense in the development of a product candidate only to be subject to significant delay and incur substantial costs in litigation before such
product candidate may be commercialized, if at all. Companies that produce reference listed drugs routinely bring claims for patent infringement against
applicants under the 505(b)(2) regulatory pathway that are seeking regulatory approval to manufacture and market generic or reformulated forms of their
reference listed drugs.

75

 
 
 
 
 
 
 
 
 
 
In the event of a successful infringement claim against us, including an infringement claim filed in response to a paragraph IV certification, we may be
required  to  pay  damages,  cease  the  development  or  commercialization  of  our  drug  products  or  product  candidates,  re-engineer  or  redevelop  our  drug
products  or  product  candidates  or  enter  into  royalty  or  licensing  agreements,  any  of  which  could  have  a  material  and  adverse  impact  on  our  business,
financial condition and results of operations. Any effort to re-engineer or redevelop our products would require additional monies and time to be expended
and may not ultimately be successful.

Infringement claims may be brought against us in the future, and we cannot assure you that we will prevail in any ensuing litigation given the complex
technical issues and inherent uncertainties involved in intellectual property litigation. Our competitors may have substantially greater resources than we do
and may be able to sustain the costs of such litigation more effectively than we can.

Patent terms may be inadequate to protect our competitive position on our product candidates for an adequate amount of time.

Patents have a limited lifespan. In the United States, the natural expiration of a patent is generally 20 years after it is filed. While various extensions may be
available, the life of a patent, and the protection it affords, is limited. Given the amount of time required for the development, testing and regulatory review
of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized.

We intend to seek extensions of patent terms in the United States and, if available, in other countries where we prosecute patents. In the United States, the
U.S. Drug Price Competition and Patent Term Restoration Act of 1984, as amended, or the Hatch-Waxman Act, permits patent owners to request a patent
term extension, based on the regulatory review period for a product, of up to five years beyond the normal expiration of the patent, which is limited to one
patent claiming the approved drug product or use in an indication (or any additional indications approved during the period of extension). However, the
applicable  authorities,  including  the  FDA  and  the  U.S.  Patent  and  Trademark  Office,  or  the  USPTO,  in  the  United  States,  and  comparable  regulatory
authorities  in  other  countries,  may  not  agree  with  our  assessment  of  whether  such  extensions  are  available,  and  may  refuse  to  grant  extensions  to  our
patents,  or  grant  more  limited  extensions  than  we  had  requested.  In  such  event,  our  competitors  may  be  able  to  take  advantage  of  our  investment  in
development and clinical trials by referencing our preclinical and clinical data in their marketing approval applications with the FDA to launch their drug
product earlier than might otherwise be the case.

If we fail to comply with various procedural, document submission, fee payment or other requirements imposed by the USPTO or comparable patent
agencies in other countries, our patent protection could be reduced or eliminated.

We are required, over the lifetime of an issued patent, to pay periodic maintenance fees to the USPTO and comparable patent agencies in other countries.
We  are  also  required  by  such  patent  agencies  to  comply  with  a  number  of  procedural,  documentary,  fee  payment  and  other  conditions  during  the  patent
application process. While an inadvertent lapse can, in many cases, be cured by payment of a late fee or other means in accordance with the applicable rules,
there are situations in which non-compliance can result in abandonment or lapse of a patent or patent application, resulting in the partial or complete loss of
patent rights in the relevant jurisdiction. Such situations include, but are not limited to:

● a failure to respond to official actions within the prescribed time limits;
● the non-payment of fees; and
● a failure to properly legalize and submit formal documents.

If  we  or  our  licensors,  which  control  the  prosecution  and  maintenance  of  patents  which  we  license,  fail  to  maintain  the  patents  or  patent  applications
covering  our  product  candidates  or  technology,  such  rights  would  be  reduced  or  eliminated  and,  consequently,  our  competitive  position,  business  and
prospects may be materially and adversely affected.

76

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Changes in patent laws or interpretations of patent laws in the United States or elsewhere may diminish the value of our intellectual property or narrow
the scope of protection of our patents.

In  September  2011,  the  Leahy-Smith  America  Invents  Act,  or  the  Leahy-Smith  Act,  was  signed  into  law,  and  many  of  the  substantive  changes  became
effective in March 2013. The Leahy-Smith Act includes a number of significant changes to U.S. patent law, including changing the United States patent
system from a “first to invent” system to a “first inventor to file” system, expanding the definition of prior art and developing a post-grant review system.
The  provisions  under  the  Leahy-Smith  Act  changed  the  way  patent  applications  are  prosecuted  and  may  also  affect  patent  litigation.  It  may  have  also
weakened our ability to obtain patent protection in the United States for applications filed after March 16, 2013.

Further,  the  post-grant  review  and  inter  partes  review  proceedings  established  under  the  Leahy-Smith  Act  have  been  used  by  certain  parties  to  cause  a
cancellation of selected or all claims in relation to the issued patents of their competitors. For a patent with an effective filing date of March 16, 2013 or
later, a petition for post-grant review can be filed by a third party in a nine-month window from issuance of the patent. A petition for inter partes review can
be filed after the nine-month period for filing a post-grant review petition has expired for a patent with an effective filing date of March 16, 2013 or later.
Post-grant review proceedings can be brought on any ground of invalidity, whereas inter partes review proceedings can only raise an invalidity challenge
based on published prior art and patents. These adversarial actions at the USPTO review patent claims without the presumption of validity afforded to U.S.
patents in lawsuits in U.S. federal courts, and use a lower burden of proof than that used in civil actions in the U.S. federal courts. Therefore, it is generally
considered  easier  for  a  competitor  or  third  party  to  have  a  U.S.  patent  invalidated  in  a  USPTO  post-grant  review  or  inter  partes  review  proceeding  than
invalidated  in  litigation  in  a  U.S.  federal  court.  We  cannot  assure  you  that  we,  our  licensors  or  our  collaborators  will  be  successful  in  defending  any
challenge by a third party in a USPTO proceeding, or, conversely, that we, our licensors or our collaborators will be successful in challenging a third party
in such a proceeding.

In  addition,  recent  court  rulings  in  the  United  States  have  narrowed  the  scope  of  patent  protection  available  and  weakened  the  rights  of  patent  owners,
particularly in the pharmaceutical industry. In 2012, the Supreme Court of the United States, or the Supreme Court, issued a decision in Mayo Collaborative
Services v. Prometheus Laboratories, Inc. invalidating patent claims directed to a process of measuring a metabolic product in a patient to optimize a drug
dosage for the patient. In 2013, the Supreme Court issued its decision in Association for Molecular Pathology v. Myriad Genetics, Inc. invalidating patent
claims directed to the breast cancer susceptibility genes BRCA1 and BRCA2. In 2017, the Supreme Court issued its decision in TC Heartland v. Kraft Food
Group Brands, holding that patentees can only sue alleged infringers in their state of incorporation. These rulings deviated from precedents and, accordingly,
have created uncertainty with regard to our ability to obtain patents in the future as well as the value of such patents, once obtained. Depending on future
actions by Congress, the U.S. courts, the USPTO and the relevant law-making bodies in other countries, the laws and regulations governing patents could
change in unpredictable ways that would affect our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the
future.

We may not be able to enforce our intellectual property rights throughout the world.

Filing,  prosecuting,  enforcing  and  defending  patents  on  our  PRINT  technology  and  our  product  candidates  throughout  the  world  may  be  prohibitively
expensive and may not be financially or commercially feasible. In countries where we have not obtained patent protection, our competitors may be able to
use our proprietary technologies to develop competing product candidates.

Also, the legal systems of non-U.S. jurisdictions may not protect intellectual property rights to the same extent or in the same manner as the laws of the
United  States,  and  we  may  face  significant  difficulty  in  enforcing  our  intellectual  property  rights  in  these  jurisdictions.  The  legal  systems  of  certain
developing  countries  may  not  favor  the  enforcement  of  patents  and  other  intellectual  property  rights.  We  may  therefore  face  difficulty  in  stopping  the
infringement or misappropriation of our patents or other intellectual property rights in those countries.

We need to protect our trademark, trade name and service mark rights to prevent competitors from taking advantage of our goodwill.

We believe that the protection of our trademark, trade name and service mark rights, such as Liquidia, the Liquidia logo and PRINT, is an important factor
in product recognition, protecting our brand, maintaining goodwill and maintaining or increasing market share. We may expend substantial cost and effort in
an attempt to register new trademarks, trade names and service marks and maintain and enforce our trademark, trade name and service mark rights. If we do
not  adequately  protect  our  rights  in  our  trademarks,  trade  names  and  service  marks  from  infringement,  any  goodwill  that  we  have  developed  in  those
trademarks could be lost or impaired.

Third parties may claim that the sale or promotion of our products, when and if approved, may infringe on the trademark, trade name and service mark
rights  of  others.  Trademark,  trade  name  and  service  mark  infringement  problems  occur  frequently  in  connection  with  the  sale  and  marketing  of
pharmaceutical  products.  If  we  become  involved  in  any  dispute  regarding  our  trademark,  trade  name  and  service  mark  rights,  regardless  of  whether  we
prevail, we could be required to engage in costly, distracting and time-consuming litigation that could harm our business. If the trademarks, trade names and
service marks we use are found to infringe upon the trademarks, trade names or service marks of another company, we could be liable for damages and be
forced  to  stop  using  those  trademarks,  trade  names  or  service  marks,  and  as  result,  we  could  lose  all  the  goodwill  that  has  been  developed  in  those
trademarks, trade names or service marks.

Risks Related to the Manufacturing of our Product Candidates

Our  product  candidates  are  based  on  our  proprietary,  novel  technology,  PRINT,  which  has  not  been  the  subject  of  FDA  manufacturing  inspections,
making it difficult to predict the time and cost of development and of subsequently obtaining regulatory approval.

Our future success depends on the successful development of our novel PRINT technology and products based on it, including LIQ861 and LIQ865. To our
knowledge,  no  regulatory  authority  has  granted  approval  to  market  or  commercialize  drugs  made  using  our  PRINT  technology.  Further,  manufacturing
facilities and processes utilizing our PRINT technology have not been the subject of FDA manufacturing inspections. We may never receive approval to
market and commercialize any product candidate that uses our PRINT technology.

Our  facilities  are  subject  to  extensive  and  ongoing  regulatory  requirements  and  failure  to  comply  with  these  regulations  may  result  in  significant
liability.

Our company and our facilities are subject to payment of fees, registration and listing requirements, ongoing review and periodic inspections by the FDA
and  other  regulatory  authorities  for  compliance  with  quality  system  regulations,  including  the  FDA’s  current  good  manufacturing  practices,  or  cGMP,
requirements. These regulations cover all aspects of the manufacturing, testing, quality control and record-keeping of our drug products. Furthermore, the
facilities where our product candidates are manufactured may be subject to inspection by the FDA before we can obtain marketing approval and remain
subject to periodic inspection even after our product candidates have received marketing approval. Suppliers of components and materials, such as active
pharmaceutical ingredients, used to manufacture our drug products are also required to comply with the applicable regulatory standards.

78

 
 
 
 
 
 
 
 
 
 
 
 
 
The manufacture of pharmaceutical products is complex and requires significant expertise and capital investment, including the development of advanced
manufacturing  techniques  and  process  controls.  We  and  any  contract  manufacturers  that  we  may  engage  in  the  future  must  comply  with  cGMP
requirements.  Manufacturers  of  pharmaceutical  products  often  encounter  difficulties  in  production,  particularly  in  scaling  up  and  validating  initial
production  and  contamination  controls.  These  problems  include  difficulties  with  production  costs  and  yields,  quality  control,  including  stability  of  the
product, quality assurance testing, operator error, shortages of qualified personnel, as well as compliance with strictly enforced federal, state and foreign
regulations. Furthermore, if microbial, viral or other contaminations are discovered in our product candidates or in the manufacturing facilities in which our
product  candidates  are  made,  such  manufacturing  facilities  may  need  to  be  closed  for  an  extended  period  of  time  to  investigate  and  remedy  the
contamination.

Compliance with these regulatory standards often requires significant expense and effort. If we or our suppliers are unable to comply with the applicable
regulatory standards or take satisfactory corrective steps in response to adverse results of an inspection, this could result in enforcement action, including,
among others, the issue of a public warning letter, a shutdown of or restrictions on our or our suppliers’ manufacturing operations, delays in approving our
drug products and refusal to permit the import or export of our drug products. Any adverse regulatory action taken against us could subject us to significant
liability and harm our business and prospects.

Our  operations  are  concentrated  in  Morrisville,  North  Carolina  and  interruptions  affecting  us  or  our  suppliers  due  to  natural  disasters  or  other
unforeseen events could materially and adversely affect our operations.

All  of  our  current  operations  are  concentrated  in  Morrisville,  North  Carolina.  A  fire,  flood,  hurricane,  earthquake  or  other  disaster  or  unforeseen  event
resulting in significant damage to our facilities could significantly disrupt or curtail or require us to cease our operations. It would be difficult, costly and
time-consuming to transfer resources from one facility to another or to repair or replace our facility in the event that it is significantly damaged. In addition,
our insurance may not be sufficient to cover all of our losses and may not continue to be available to us on acceptable terms, or at all. In addition, if one of
our suppliers experiences a similar disaster or unforeseen event, we could face significant delays in obtaining our supplies or be required to source supplies
from an alternative supplier and may incur substantial costs as a result. Any significant uninsured loss, prolonged or repeated disruption to operations or
inability to operate, experienced by us or by our suppliers, could materially and adversely affect our business, financial condition and results of operations.

We may not be able to engage third-party contract manufacturing organizations, or CMOs, to manufacture our drug products, if and when approved, on
a commercial scale to meet commercial demand for our drug products.

We may, in the future, need to rely on third-party CMOs or enter into contractual arrangements with third parties to manufacture our drug products, if and
when approved, on a commercial scale. However, we cannot assure you that we will be able to contract with such third parties on acceptable terms, if at all,
or that such third parties will satisfy our quality standards or meet our supply requirements in a timely manner, if at all. In addition, only a limited number of
manufacturers are capable of supplying pharmaceutical products. The manufacturing process for our drug products will be highly regulated, and we will
need to contract with manufacturers that can meet the relevant regulatory requirements on an ongoing basis. If the third-party manufacturers with whom we
contract fail to perform their obligations, we may not be able to meet commercial demand for our drug products, which would have a material and adverse
impact on our business.

System failures may disrupt our business operations and delay our product development programs and commercialization activities.

Our systems, including computer systems, and those of our collaborators, contractors and consultants are vulnerable to, among others, unauthorized access,
equipment failure and damage from computer viruses as well as cyber hackers. In the event of a material system failure or security breach of, or significant
damage to, our systems, our business operations may be disrupted, and our product development programs and commercialization activities may be delayed.
For  example,  failure  of,  or  damage  to,  equipment  leading  to  a  loss  of  our  clinical  trial  data  could  result  in  delays  to  the  process  of  obtaining  marketing
approval  for  our  product  candidates,  as  well  as  significant  and  unexpected  expenditure  to  recover  or  reproduce  the  lost  data.  To  the  extent  that  any
disruption or damage to, or security breach of, the systems of our collaborators, contractors or consultants results in a loss of our data or applications, or the
disclosure of our confidential information, our business may be adversely affected.

Risks Related to Healthcare Regulation

We are subject to various laws and regulations, such as healthcare fraud and abuse laws, false claim laws and health information privacy and security
laws, among others, and failure to comply with these laws and regulations may have an adverse effect on our business.

Healthcare providers, physicians and third-party payors often play a primary role in the recommendation and prescription of any drug products for which we
may obtain marketing approval. Our current and future arrangements with healthcare providers, physicians, third-party payors and customers, and our sales,
marketing and educational activities, may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations (at the federal and state
level) that may constrain our business or financial arrangements and relationships through which we market, sell and distribute our drug products for which
we obtain marketing approval.

In addition, we may be subject to transparency laws and patient privacy regulation by both the federal government and the states in which we conduct our
business.

The laws that may affect our ability to operate include, but are not limited to, the following:

● the federal Anti-Kickback Statute, which prohibits, among other things, persons and entities including pharmaceutical manufacturers from, among
other things, knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, overtly or covertly, in cash or in
kind, to induce or reward, or in return for, either the referral of an individual for or the purchase, lease, order or recommendation of an item or
service for which payment may be made, in whole or in part, under federal healthcare programs such as the Medicare and Medicaid programs. This
statute  has  been  interpreted  broadly  to  apply  to,  among  other  things,  arrangements  between  pharmaceutical  manufacturers  on  the  one  hand  and
prescribers, purchasers and formulary managers on the other hand. The term “remuneration” expressly includes kickbacks, bribes or rebates and
also has been broadly interpreted to include anything of value, including, for example, gifts, discounts, waivers of payment, ownership interest and
providing  anything  at  less  than  its  fair  market  value.  There  are  a  number  of  statutory  exceptions  and  regulatory  safe  harbors  protecting  certain
common activities from prosecution or other regulatory sanctions, however, the exceptions and safe harbors are drawn narrowly, and practices that
do  not  fit  squarely  within  an  exception  or  safe  harbor  may  be  subject  to  scrutiny.  The  failure  to  meet  all  of  the  requirements  of  a  particular
applicable statutory exception or regulatory safe harbor does not make the conduct per se illegal under the federal Anti-Kickback Statute. Instead,
the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all of its facts and circumstances. Our
practices may not meet all of the criteria for safe harbor protection from federal Anti-Kickback Statute liability in all cases. A person or entity does
not need to have actual knowledge of the federal Anti-Kickback Statute or specific intent to violate it to have committed a violation. In addition,
the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a
false or fraudulent claim for purposes of the False Claims Act. The U.S. Patient Protection and Affordable Care Act of 2010, as amended by the
Health  Care  and  Education  Reconciliation  Act  of  2010,  or  collectively  the  ACA,  amended  the  False  Claims  Act  to  provide  that  a  claim  that
includes items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim under the False
Claims Act;

80

 
 
 
 
 
 
 
 
 
● the federal civil and criminal false claims laws and civil monetary penalty laws, including the False Claims Act, which prohibits individuals or
entities from, among other things, knowingly presenting, or causing to be presented, claims for payment to, or approval by, the federal government
that are false, fictitious or fraudulent or knowingly making, using or causing to be made or used, a false record or statement material to a false or
fraudulent claim to avoid, decrease or conceal an obligation to pay money to the federal government. As a result of a modification made by the
Fraud  Enforcement  and  Recovery  Act  of  2009,  a  claim  includes  “any  request  or  demand”  for  money  or  property  presented  to  the  federal
government, directly or indirectly. Although we do not submit claims directly to payors, manufacturers can be held liable under these laws if they
are  deemed  to  “cause”  the  submission  of  false  or  fraudulent  claims  by,  for  example,  providing  inaccurate  billing  or  coding  information  to
customers, promoting a product off-label, marketing products of sub-standard quality, or, as noted above, paying a kickback that results in a claim
for items or services. In addition, our activities relating to the reporting of wholesaler or estimated retail prices for our products, the reporting of
prices used to calculate Medicaid rebate information and other information affecting federal, state and third-party reimbursement for our products,
and  the  sale  and  marketing  of  our  products,  are  subject  to  scrutiny  under  this  law.  For  example,  several  pharmaceutical  and  other  healthcare
companies have faced enforcement actions under these laws for allegedly inflating drug prices they report to pricing services, which in turn were
used  by  the  government  to  set  Medicare  and  Medicaid  reimbursement  rates,  and  for  allegedly  providing  free  product  to  customers  with  the
expectation  that  the  customers  would  bill  federal  programs  for  the  product.  The  False  Claims  Act  also  permits  a  private  individual  acting  as  a
“whistleblower”  to  bring  actions  on  behalf  of  the  federal  government  alleging  violations  of  the  False  Claims  Act  and  to  share  in  any  monetary
recovery. Penalties under the False Claims Act include treble damages and per claim penalty amounts ranging from $11,665 to $23,331. The ACA
further codified case law that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a per se
false or fraudulent claim for purposes of the federal False Claims Act;

● the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes criminal and civil liability for knowingly and
willfully  executing,  or  attempting  to  execute,  a  scheme  to  defraud  or  to  obtain,  by  means  of  false  or  fraudulent  pretenses,  representations  or
promises, any money or property owned by, or under the control or custody of, any healthcare benefit program, including private third-party payors
and  knowingly  and  willfully  falsifying,  concealing  or  covering  up  by  trick,  scheme  or  device,  a  material  fact  or  making  any  materially  false,
fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services;

● HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act  of  2009,  or  HITECH,  and  their  respective
implementing  regulations,  including  the  Final  Omnibus  Rule  published  on  January  25,  2013,  impose,  among  other  things,  obligations,  impose
requirements relating to the privacy, security and transmission of individually identifiable health information. Following enactment of the HITECH
Act, HIPAA’s privacy and security standards now directly apply to business associates of covered entities that receive or obtain protected health
information in connection with providing a service on behalf of a covered entity. We are not a covered entity under HIPAA but in certain situations,
we  may  be  considered  a  business  associate.  HITECH  also  created  four  new  tiers  of  civil  monetary  penalties,  gave  state  attorneys  general  new
authority  to  file  civil  actions  for  damages  or  injunctions  in  federal  court  to  enforce  the  federal  HIPAA  laws  and  seek  attorney’s  fees  and  costs
associated  with  pursuing  federal  civil  actions.  The  U.S.  Department  of  Health  and  Human  Services  Office  for  Civil  Rights,  or  the  OCR,  has
increased its focus on compliance and continues to train state attorneys general for enforcement purposes. The OCR has recently increased both its
efforts to audit HIPAA compliance and its level of enforcement;

● even  when  HIPAA  does  not  apply,  according  to  the  U.S.  Federal  Trade  Commission,  or  the  FTC,  failing  to  take  appropriate  steps  to  keep
consumers’  personal  information  secure  constitutes  unfair  acts  or  practices  in  or  affecting  commerce  in  violation  of  Section  5(a)  of  the  Federal
Trade  Commission  Act,  or  the  FTCA.  The  FTC  expects  a  company’s  data  security  measures  to  be  reasonable  and  appropriate  in  light  of  the
sensitivity and volume of consumer information it holds, the size and complexity of its business, and the cost of available tools to improve security
and reduce vulnerabilities. Medical data is considered sensitive data that merits stronger safeguards. The FTC’s guidance for appropriately securing
consumers’ personal information is similar to what is required by the HIPAA Security Rule. The FTC’s authority under Section 5 is concurrent
with HIPAA’s jurisdiction and with any action taken under state law;

81

 
 
 
 
 
 
 
 
 
 
● the  federal  physician  payment  transparency  requirements,  sometimes  referred  to  as  the  “Physician  Payments  Sunshine  Act,”  created  under  the
ACA  which  requires  applicable  manufacturers  of  covered  drugs,  devices,  biologics  and  medical  supplies  for  which  payment  is  available  under
Medicare, Medicaid or the State Children’s Health Insurance Program (with certain exceptions) to annually report to the Centers for Medicare and
Medicaid  Services,  or  CMS,  information  related  to  certain  payments  or  other  transfers  of  value  made  or  distributed  to  physicians  (defined  to
include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, as well as ownership and investment interests held by
physicians and their immediate family members. Federal legislation enacted in 2018 has extended the scope of reporting requirements to apply to
payments and transfers of value to not only physicians, but also physician assistants, nurse practitioners, and other mid-level practitioners (with
reporting requirements going into effect in 2022 for payments made in 2021);

● analogous state laws and regulations, such as state anti-kickback and false claims laws, may apply to items or services reimbursed by any third-
party payor, including commercial insurers, and in some cases may apply regardless of payor (i.e., even for self-pay scenarios). 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  in  addition  to  requiring  drug  manufacturers  to  report  pricing  and  marketing  information,
including, among other things, information related to payments to physicians and other healthcare providers or marketing expenditures, state and
local  laws  that  require  the  registration  of  pharmaceutical  sales  representatives,  and  state  laws  governing  the  privacy  and  security  of  health
information and the use of prescriber-identifiable data in certain circumstances. Many of these state laws differ from each other in significant ways
and may not have the same effect, and may apply more broadly than their federal counterparts, thus complicating compliance efforts (for example,
California recently enacted legislation — the CCPA, which went into effect on January 1, 2020 and among other things, creates new data privacy
obligations for covered companies and provides new privacy rights to California residents, including the right to opt out of certain disclosures of
their  information,  and  creates  a  private  right  of  action  with  statutory  damages  for  certain  data  breaches,  thereby  potentially  increasing  risks
associated with a data breach; although the law includes limited exceptions, including for certain information collected as part of clinical trials as
specified in the law, it may regulate or impact our processing of personal information depending on the context, and it remains unclear what, if any,
modifications will be made to this legislation or how it will be interpreted); and

● price reporting laws that require us to calculate and report complex pricing metrics to government programs, where such reported prices may be
used  in  the  calculation  of  reimbursements  or  discounts  on  our  drug  products.  Participation  in  such  programs  and  compliance  with  their
requirements may subject us to increased infrastructure costs and potentially limit our ability to price our drug products.

Further, we are subject to a number of environmental and health and safety laws and regulations, including those governing laboratory processes and the
handling, use, storage, treatment and disposal of hazardous materials and waste.

Because of the breadth of these laws and the narrowness of the statutory exceptions and regulatory safe harbors available under such laws, it is possible that
certain business activities could be subject to challenge under one or more of such laws. The scope and enforcement of each of these laws is uncertain and
subject to rapid change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and regulations. Federal and
state enforcement bodies have recently increased their scrutiny of interactions between pharmaceutical companies and providers and patients, which has led
to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. Ensuring that business arrangements with third parties
comply with applicable healthcare laws, as well as responding to possible investigations by government authorities, can be time- and resource-consuming
and can divert management’s attention from the business, even if the government ultimately finds that no violation has occurred.

If our operations are found to be in violation of any of the laws or regulations described above or any other laws or government regulations that apply to us,
we  may  be  subject  to  penalties,  including,  but  not  limited  to,  criminal,  civil  and  administrative  penalties,  damages,  fines,  disgorgement,  individual
imprisonment, possible exclusion from participation in Medicare, Medicaid or other government healthcare programs, injunctions, private qui tam actions
brought by individual whistleblowers in the name of the government and the curtailment or restructuring of our operations as well as additional reporting
obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these
laws, any of which could adversely affect our ability to operate our business and our results of operations.

82

 
 
 
 
 
 
 
 
 
 
 
Our failure to comply with data protection laws and regulations could lead to government enforcement actions and significant penalties against us, and
adversely impact our operating results.

European  Union  member  states  and  other  foreign  jurisdictions,  including  Switzerland,  have  adopted  data  protection  laws  and  regulations  which  impose
significant compliance obligations. Moreover, the collection and use of personal health data in the European Union, which was formerly governed by the
provisions of the European Union Data Protection Directive, was replaced with the European Union General Data Protection Regulation, or the GDPR, in
May 2018. The GDPR, which is wide-ranging in scope, imposes several requirements relating to the consent of the individuals to whom the personal data
relates, the information provided to the individuals, the security and confidentiality of the personal data, data breach notification and the use of third-party
processors  in  connection  with  the  processing  of  personal  data.  The  GDPR  also  imposes  strict  rules  on  the  transfer  of  personal  data  out  of  the  European
Union to the United States, provides an enforcement authority and imposes large penalties for noncompliance, including the potential for fines of up to €20
million or 4% of the annual global revenues of the noncompliant company, whichever is greater. The recent implementation of the GDPR has increased our
responsibility  and  liability  in  relation  to  personal  data  that  we  process,  including  in  clinical  trials,  and  we  may  in  the  future  be  required  to  put  in  place
additional  mechanisms  to  ensure  compliance  with  the  GDPR,  which  could  divert  management’s  attention  and  increase  our  cost  of  doing  business.  In
addition, new regulation or legislative actions regarding data privacy and security (together with applicable industry standards) may increase our costs of
doing business. In this regard, we expect that there will continue to be new proposed laws, regulations and industry standards relating to privacy and data
protection in the United States, the European Union and other jurisdictions, and we cannot determine the impact such future laws, regulations and standards
may have on our business.

Legislative or regulatory reform of the healthcare system in our target markets may affect our operations and profitability.

In recent years, there have been numerous initiatives on the federal and state levels in the United States for comprehensive reforms affecting the payment
for,  the  availability  of  and  reimbursement  for  healthcare  services.  There  have  been  a  number  of  federal  and  state  proposals  during  the  last  few  years
regarding  the  pricing  of  pharmaceutical  and  biopharmaceutical  products,  limiting  coverage  and  reimbursement  for  drugs  and  other  medical  products,
government control and other changes to the healthcare system in the United States. Current and future U.S. legislative healthcare reforms may result in
price controls and other restrictions for any approved products, if covered, and could seriously harm our business. Given that drug pricing controls is a key
legislative and administration priority, it is likely that additional pricing controls will be enacted and could harm our business, financial condition and results
of operations.

The ACA, which was signed into law in the United States in March 2010, contained several provisions affecting the pharmaceutical industry:

● the Medicaid Drug Rebate Program requires pharmaceutical manufacturers to enter into and have in effect a national rebate agreement with the

Secretary of the Department of HHS, as a condition of Medicare Part B and Medicaid coverage of the manufacturer’s outpatient drugs furnished to
Medicaid patients;

● the expansion of eligibility criteria for Medicaid programs which potentially increases both the volume of sales and manufacturers’ Medicaid

rebate liability;

● in order for a pharmaceutical product to receive federal reimbursement under the Medicare Part B and Medicaid programs or to be sold directly to
U.S. government agencies, the manufacturer must extend discounts to entities eligible to participate in the 340B Drug Pricing Program. The
required 340B discount on a given product is calculated based on the AMP and Medicaid rebate amounts reported by the manufacturer;

83

 
 
 
 
 
 
 
 
 
 
 
 
 
● the ACA imposed a requirement on manufacturers of branded drugs to provide a 70% discount off the negotiated price of branded drugs dispensed

to Medicare Part D patients in the coverage gap (i.e., the donut hole);

● the ACA imposed an annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs, apportioned among
these entities according to their market share in certain government healthcare programs, although this fee would not apply to sales of certain
products approved exclusively for orphan indications;

● the ACA implemented the Physician Payments Sunshine Act;

● the ACA requires annual reporting of drug samples that manufacturers and distributors provide to physicians;

● the ACA expanded healthcare fraud and abuse laws in the United States, including the False Claims Act and the federal Anti-Kickback Statute,

new government investigative powers and enhanced penalties for non-compliance;

● the ACA established a licensing framework for follow-on biologics; and

● the ACA established the new Patient-Centered Outcomes Research Institute to oversee, identify priorities in and conduct comparative clinical

effectiveness research, along with the funding for such research.

The  Trump  Administration  and  the  Congressional  Republicans  have  proposed  several  efforts  to  repeal  and  replace  the  ACA.  President  Trump  has  also
signed Executive Orders and other directives designed to delay the implementation of certain provisions of the ACA or otherwise circumvent some of the
requirements for health insurance mandated by the ACA. Additionally, on December 15, 2019, a federal district court in Texas struck down the ACA in its
entirety,  finding  that  the  TCJA  renders  the  individual  mandate  unconstitutional.  The  judge  further  concluded  in  Texas  v.  Azar  that  since  the  individual
mandate  is  “essential”  to  the  ACA,  it  could  not  be  severed  from  the  rest  of  the  ACA  and  therefore,  the  entire  ACA  was  unconstitutional.  Despite  its
decision,  however,  the  court  did  not  issue  an  injunction  and  therefore,  immediate  compliance  is  not  required.  In  addition,  the  Trump  Administration
announced that it will continue to administer the law until a formal decision is made by the U.S. Supreme Court. The Supreme Court has not yet announced
when or whether it will hear a challenge in Texas v. United States, though it is highly anticipated that it will do so next term (beginning October 2020).
Apart from Texas v. United States, ACA litigation continues across the country in district and appellate courts, and before the Supreme Court. The Supreme
Court will issue at least two ACA-related decisions before the end of its current term: one on the risk corridors program (Maine Community Health Options
v.  United  States)  and  the  other  on  religious  or  moral  exemptions  to  the  contraceptive  mandate  (Trump  v.  Pennsylvania  and  Little  Sisters  of  the  Poor  v.
Pennsylvania). Both decisions are expected before July 2020. It is unclear how the eventual decisions from the Supreme Court and the various other courts
across the country to repeal and replace the ACA will impact the ACA and our business. It is also unclear how regulations and sub-regulatory policy, which
fluctuate continually, may affect interpretation and implementation of the ACA and its practical effects on our business, particularly entering an election
year.

Further, there has been increasing legislative and enforcement interest in the United States with respect to drug pricing practices. Specifically, there have
been  several  recent  U.S.  Congressional  inquiries  and  proposed  and  enacted  federal  and  state  legislation  designed  to,  among  other  things,  bring  more
transparency  to  drug  pricing,  reduce  the  cost  of  prescription  drugs  under  Medicare,  review  the  relationship  between  pricing  and  manufacturer  patient
programs  and  reform  government  program  reimbursement  methodologies  for  drugs.  Recent  federal  budget  proposals  have  included  measures  to  permit
Medicare Part D plans to negotiate the price of certain drugs under Medicare Part B, to allow some states to negotiate drug prices under Medicaid, and to
eliminate cost sharing for generic drugs for low-income patients. The U.S. Congress and the Trump Administration have indicated that they will continue to
seek new legislative and administrative measures to control drug costs, including by addressing the role of PBMs in the supply chain. Drug pricing is and
will remain a key bipartisan issue in the coming year. If drug pricing reform is not meaningfully addressed before the 2020 election, policies to be pursued
in  the  future  may  be  more  aggressive,  regardless  of  which  party  controls  the  White  House.  At  the  state  level,  legislatures  have  increasingly  passed
legislation  and  implemented  regulations  designed  to  control  pharmaceutical  and  biological  product  pricing,  including  price  or  patient  reimbursement
constraints,  discounts,  restrictions  on  certain  product  access  and  marketing  cost  disclosure  and  transparency  measures,  and,  in  some  cases,  designed  to
encourage importation from other countries and bulk purchasing. The boom in state laws targeting drug pricing is unprecedented and the requirements are
not uniform from state to state, creating additional compliance and commercialization challenges for manufacturers.

We are unable to predict the future course of federal or state healthcare legislation in the United States directed at broadening the availability of healthcare
and  containing  or  lowering  the  cost  of  healthcare,  including  drugs  and  biologics.  The  fate  of  the  ACA  and  any  further  changes  in  the  law  or  regulatory
framework that reduce our revenue or increase our costs could also have a material and adverse effect on our business, financial condition and results of
operations.

Healthcare laws and regulations may affect the pricing of our drug products and may affect our profitability.

In certain countries, the government may provide healthcare at a subsidized cost to consumers and regulate prices, patient eligibility or third-party payor
reimbursement  policies  to  control  the  cost  of  drug  products.  Such  a  system  may  lead  to  inconsistent  pricing  of  our  drug  products  from  one  country  to
another. The availability of our drug products at lower prices in certain countries may undermine our sales in other countries where our drug products are
more  expensive.  In  addition,  certain  countries  may  set  prices  by  reference  to  the  prices  of  our  drug  products  in  other  countries.  Our  inability  to  secure
adequate prices in a particular country may adversely affect our ability to obtain an acceptable price for our drug products in existing and potential markets.
If  we  are  unable  to  obtain  a  price  for  our  drug  products  that  provides  an  appropriate  return  on  our  investment,  our  profitability  may  be  materially  and
adversely affected.

Risks Related to our Employees

We depend on skilled labor, and our business and prospects may be adversely affected if we lose the services of our skilled personnel, including those in
senior management, or are unable to attract new skilled personnel.

Our  ability  to  continue  our  operations  and  manage  our  potential  future  growth  depends  on  our  ability  to  hire  and  retain  suitably  skilled  and  qualified
employees,  including  those  in  senior  management,  in  the  long-term.  Due  to  the  specialized  nature  of  our  work,  there  is  a  limited  supply  of  suitable
candidates.  We  compete  with  other  biotechnology  and  pharmaceutical  companies,  educational  and  research  institutions  and  government  entities,  among
others, for research, technical and clinical personnel. In addition, in order to manage our potential future growth effectively, we will need to improve our
financial controls and systems and, as necessary, recruit sales, marketing, managerial and finance personnel. If we are unable to attract and retain skilled
personnel, including in particular Neal Fowler, our Chief Executive Officer, our business and prospects may be materially and adversely affected.

Our  employees  and  our  independent  contractors,  principal  investigators,  CROs,  CMOs,  consultants  or  commercial  collaborators,  as  well  as  their
respective subcontractors, if any, may engage in misconduct or fail to comply with certain regulatory standards and requirements, which could expose
us to liability and adversely affect our reputation.

Our employees and our independent contractors, principal investigators, CROs, CMOs, consultants or commercial collaborators, as well as their respective
subcontractors, if any, may engage in fraudulent conduct or other illegal activity, which may include intentional, reckless or negligent conduct that violates,
among others, (a) FDA laws and regulations, or those of comparable regulatory authorities in other countries, including those laws that require the reporting
of true, complete and accurate information to the FDA, (b) manufacturing standards, (c) healthcare fraud and abuse laws or (d) laws that require the true,
complete and accurate reporting of financial information or data. For example, such persons may improperly use or misrepresent information obtained in the
course of our clinical trials, create fraudulent data in our preclinical studies or clinical trials or misappropriate our drug products, which could result in
regulatory sanctions being imposed on us and cause serious harm to our reputation. It is not always possible for us to identify or deter misconduct by our
employees and third parties, and any precautions we may take to detect or prevent such misconduct may not be effective. Any misconduct or failure by our
employees and our independent contractors, principal investigators, CROs, CMOs, consultants or commercial collaborators, as well as their respective
subcontractors, if any, to comply with the applicable laws or regulations may subject us to enforcement action or otherwise expose us to liability or
compliance costs, which, depending on the nature of the violation, may include but not necessarily be limited to, criminal, civil and administrative penalties,
damages, fines, disgorgement, individual imprisonment, possible exclusion from participation in Medicare, Medicaid or other government healthcare
programs, injunctions, private qui tam actions brought by individual whistleblowers in the name of the government and the curtailment or restructuring of
our operations as well as additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to
resolve allegations of non-compliance with these laws. If any action is instituted against us as a result of the alleged misconduct of our employees or other
third parties, regardless of the final outcome, our reputation may be adversely affected and our business may suffer as a result. If we are unsuccessful in
defending against any such action, we may also be liable to significant fines or other sanctions, which could have a material and adverse effect on us.

Risks Related to our Common Stock

An active trading market for our common stock may not be sustainable. If an active trading market is not sustained, our ability to raise capital in the
future may be impaired.

We completed our initial public offering in July 2018. Prior to this time, there was no public market for our common stock. Although our common stock is
listed  on  the  Nasdaq  Capital  Market,  an  active  trading  market  for  our  shares  may  not  be  sustained.  If  an  active  market  for  our  common  stock  is  not
sustained, it may be difficult for you to sell shares of our common stock without depressing the market price for the shares or at all. An inactive trading
market may also impair our ability to raise capital to continue to fund operations by selling shares and may impair our ability to acquire other companies or
technologies by using our shares as consideration.

Future sales of our common stock or securities convertible into our common stock in the public market could cause our stock price to fall.

Our stock price could decline as a result of sales of a large number of shares of our common stock or the perception that these sales could occur. These sales,
or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we
deem appropriate.

As of March 1, 2020, 28,365,093 shares of our common stock were outstanding, of which 23,041,325 shares of common stock, or 81.2% of our outstanding
shares as of March 1, 2020, are freely tradable without restriction or further registration under the Securities Act of 1933, as amended, or the Securities Act,
unless held by our “affiliates,” as that term is defined in Rule 144 under the Securities Act, or Rule 144. The resale of the remaining 5,323,768 shares held
by our stockholders is currently prohibited or otherwise restricted as a result of securities law provisions. Shares issued upon the exercise of stock options
outstanding under our equity incentive plans or pursuant to future awards granted under those plans will become available for sale in the public market to
the extent permitted by the provisions of applicable vesting schedules, any applicable market standoff and lock-up agreements, and Rule 144 and Rule 701
under the Securities Act.

As of March 1, 2020, the holders of approximately 5.1 million shares, or 18.0%, of our outstanding shares as of March 1, 2020, have rights, subject to some
conditions, to require us to file registration statements covering the sale of their shares or to include their shares in registration statements that we may file
for  ourselves  or  other  stockholders.  We  have  also  registered  the  offer  and  sale  of  all  shares  of  common  stock  that  we  may  issue  under  our  equity
compensation plans, including the employee stock purchase plan. Once we register the offer and sale of shares for the holders of registration rights, they can
be freely sold in the public market upon issuance or resale (as applicable), subject to lock-up agreements, if any.

We  are  party  to  an  Open  Market  Sale  Agreement℠  with  Jefferies  LLC,  as  sales  agent  and/or  principal,  pursuant  to  which  we  may  offer  shares  of  our
common stock from time to time through “at-the-market” offerings. We are not obligated to make or continue to make any sale of shares of our common
stock under the “at-the-market” offerings. Although any sale of securities pursuant to the “at-the-market” offerings will result in a concomitant increase in
cash for each share sold, it may result in stockholder dilution and may cause our share price to fall. 

86

 
 
 
 
 
 
 
 
 
 
We expect that the market price of our common stock may be volatile, and you may lose all or part of your investment.

The trading prices of the securities of pharmaceutical and biotechnology companies have been highly volatile. As such, the trading price of our common
stock may be highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control. The market
price for our common stock may be influenced by many factors, including:

● results of clinical trials of LIQ861, LIQ865 or any product candidate we may develop, or those of our competitors;
● our cash resources;
● the success of competitive products or technologies;
● potential approvals of any product candidate we may develop for marketing by the FDA or equivalent foreign regulatory authorities or any failure

to obtain such approvals;

● our involvement in significant lawsuits, including stockholder or patent litigation, including inter partes review proceedings;
● regulatory or legal developments in the United States and other countries;
● the results of our efforts to commercialize any product candidate we may develop;
● developments or disputes concerning patents or other proprietary rights;
● the recruitment or departure of key personnel;
● the level of expenses related to any of our product candidates or clinical development programs;
● the results of our efforts to discover, develop, acquire or in-license additional product candidates or products;
● actual or anticipated changes in estimates as to financial results, development timelines or recommendations by securities analysts;
● variations in our financial results or those of companies that are perceived to be similar to us;
● changes in the structure of healthcare payment systems;
● market  conditions  in  the  pharmaceutical  and  biotechnology  sectors  and  issuance  of  new  or  changed  securities  analysts’  reports  or

recommendations;

● general economic, industry and market conditions; and
● the other factors described in this “Risk Factors” section.

The stock market in general, and market prices for the securities of pharmaceutical companies like ours in particular, have from time to time experienced
volatility  that  often  has  been  unrelated  to  the  operating  performance  of  the  underlying  companies.  These  broad  market  and  industry  fluctuations  may
adversely  affect  the  market  price  of  our  common  stock,  regardless  of  our  operating  performance.  Stock  prices  of  many  pharmaceutical  companies  have
fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. In several recent situations when the market price of
a  stock  has  been  volatile,  holders  of  that  stock  have  instituted  securities  class  action  litigation  against  the  company  that  issued  the  stock.  If  any  of  our
stockholders  were  to  bring  a  lawsuit  against  us,  the  defense  and  disposition  of  the  lawsuit  could  be  costly  and  divert  the  time  and  attention  of  our
management and harm our operating results.

Future sales and issuances of equity securities, convertible securities or other securities could result in additional dilution of the percentage ownership
of holders of our common stock.

Our stockholders may experience dilution upon future equity issuances, including any other convertible debt or equity securities we may issue in the future,
the exercise of stock options to purchase common stock granted to our employees, consultants and directors, including options to purchase common stock
granted under our stock option and equity incentive plans, the issuance of common stock in settlement of previously issued awards under our stock option
and equity incentive plans that may vest in the future or the issuance of common stock pursuant to our employee stock purchase plan.

87

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We expect that significant additional capital will be needed in the future to continue our planned operations. To raise capital, we may sell equity securities,
convertible securities or other securities in one or more transactions at prices and in a manner we determine from time to time. If we sell equity securities,
convertible  securities  or  other  securities,  current  investors  may  be  materially  diluted  by  such  subsequent  sales.  We  may  also  need  our  stockholders  to
authorize  the  issuance  of  additional  shares  of  common  stock  under  our  amended  and  restated  certificate  of  incorporation  if  we  do  not  have  sufficient
authorized  shares  to  raise  such  additional  capital  or  issue  future  awards  under  our  incentive  plan.  New  investors  could  also  gain  rights,  preferences  and
privileges senior to those of holders of our existing equity securities.

Our principal stockholders and management own a significant percentage of our stock and will be able to exercise significant influence over matters
subject to stockholder approval.

Our executive officers, directors and principal stockholders, together with their respective affiliates, beneficially owned 39.5% of our capital stock as of
March 1, 2020, of which 3.2% are beneficially owned by our executive officers and directors. Accordingly, our executive officers, directors and principal
stockholders have significant influence in determining the composition of the Board, and voting on all matters requiring stockholder approval, including
mergers and other business combinations, and continue to have significant influence over our operations. This concentration of ownership could have the
effect of delaying or preventing a change in our control or otherwise discouraging a potential acquirer from attempting to obtain control of us that you may
believe are in your best interests as one of our stockholders. This in turn could have a material adverse effect on our stock price and may prevent attempts by
our stockholders to replace or remove the Board or management.

If securities or industry analysts do not publish research reports about our business, or if they issue an adverse opinion about our business, our stock
price and trading volume could decline.

The trading market for our common stock may be influenced by the research and reports that industry or securities analysts publish about us or our business.
If one or more of these analysts ceases research coverage of us, fails to regularly publish reports on us or issues an adverse opinion about our business, we
could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

As a public company, we are obligated to develop and maintain proper and effective internal control over financial reporting and any failure to do so
may adversely affect investor confidence in us and, as a result, the trading price of our shares. The results of our 2019 assessment of the effectiveness of
internal control over financial reporting, or ICFR, indicate that we have multiple material weaknesses.

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.  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 stock. In addition, any future testing by us conducted
in connection with Section 404 of the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act, or the subsequent testing by our independent
registered public accounting firm, may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses or that
may require prospective or retroactive changes to our financial statements or identify other areas for further attention or improvement.

88

 
 
 
 
 
 
 
 
 
As required by the Sarbanes Oxley Act of 2002 and commencing with the fiscal year ended December 31, 2019, we are required to furnish a report by
management on, among other things, the effectiveness of our ICFR for the fiscal year ended December 31, 2019. In connection with the assessment of the
effectiveness of our ICFR, our management identified the following material weaknesses that existed as of December 31, 2019:

During 2019, we experienced significant turnover in finance personnel that reduced the complement and skill of the resources within the Company.  As a
result, we did not maintain an effective control environment as we lacked a sufficient complement of resources with an appropriate level of knowledge,
experience  and  training  to  design,  maintain  and  monitor  our  ICFR  commensurate  with  our  financial  reporting  requirements.  As  a  result,  this  material
weakness contributed to the following material weaknesses: 

● We  did  not  design  and  maintain  controls  to  ensure  adequate  segregation  of  duties  within  our  financial  reporting  function,  including  the
preparation and review of journal entries.  Specifically, some key accounting personnel had the ability to both prepare and post journal entries
without an independent review by someone without the ability to prepare and post journal entries.

● We  did  not  design  and  maintain  effective  controls  over  certain  information  technology  general  controls  for  information  systems  that  are
relevant to the preparation of our financial statements.  Specifically, we did not design and maintain effective user access controls to ensure
appropriate  segregation  of  duties  and  that  adequately  restrict  user  and  privileged  access  to  financial  applications  and  data  to  appropriate
Company personnel.

These material weaknesses did not result in a material misstatement of the annual or interim financial statements.  Additionally, these material weaknesses
could  result  in  a  misstatement  of  the  relevant  account  balances  or  disclosures  that  would  result  in  a  material  misstatement  to  the  annual  or  interim
consolidated financial statements that would not be prevented or detected.

Additionally, we could be subject to regulatory scrutiny, a loss of public and investor confidence, and to litigation from investors and stockholders, all of
which could have a material adverse effect on our business and the trading price of our shares. Subsequent to our December 31, 2019 year end, we began
taking  a  number  of  actions,  including  designing  and  implementing  new  controls  and  revising  existing  controls,  in  order  to  remediate  the  material
weaknesses described above. See Item 9A. Controls and Procedures in this annual report. Failure to remedy any material weakness in our internal control
over financial reporting, or to implement or maintain other effective control systems required of public companies, could result in charges by the SEC with
violating  the  books  and  records  and  internal  control  provisions  of  the  federal  securities  laws  which  may  result  in  penalties  and  fines  to  our  company,
directors and officers, and also could restrict our future access to the capital markets.

For  as  long  as  we  are  an  “emerging  growth  company”  under  the  Jumpstart  Our  Business  Startups  Act  of  2012,  as  amended,  or  the  JOBS  Act,  our
independent registered public accounting firm will not be required to attest to the effectiveness of our internal controls over financial reporting pursuant to
Section 404. We could be an emerging growth company for up to an additional four years. An independent assessment of the effectiveness of our internal
controls could detect additional problems that our management’s assessment might not. Undetected material weaknesses in our internal controls could lead
to financial statement restatements and require us to incur additional remediation expenses.

We are an “emerging growth company,” as defined in the JOBS Act, and as a result of the reduced disclosure and governance requirements applicable
to emerging growth companies, our common stock may be less attractive to investors.

We are an “emerging growth company,” as defined in the JOBS Act, and we 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,  and  exemptions  from  the  requirements  of  holding  a  nonbinding  advisory  vote  on  executive  compensation  and  stockholder
approval of any golden parachute payments not previously approved. We cannot predict if investors will find our common stock less attractive because we
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  take  advantage  of  these  reporting  exemptions  until  we  are  no  longer  an  “emerging  growth
company.”  We  will  remain  an  “emerging  growth  company”  until  the  earliest  of  (i)  the  last  day  of  the  fiscal  year  in  which  we  have  total  annual  gross
revenues of $1.07 billion or more, (ii) the last day of 2023, (iii) the date on which we have issued more than $1.0 billion in nonconvertible debt during the
previous three years or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the SEC.

89

 
 
 
 
 
 
 
 
 
 
 
 
We will continue to incur increased costs as a result of operating as a public company, and our management will be required to devote substantial time
to new compliance initiatives and corporate governance practices.

As  a  public  company,  we  are  incurring  significant  legal,  accounting  and  other  expenses  that  we  did  not  incur  as  a  private  company,  including  costs
associated with public company reporting requirements. We have also incurred costs associated with recently adopted corporate governance requirements,
including requirements of the U.S. Securities and Exchange Commission and the Nasdaq Stock Market LLC, or Nasdaq. These rules and regulations have
increased our legal and financial compliance costs and made some activities more time-consuming and costly. These rules and regulations also 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 that we received as a private company. As a result, it may be more difficult for us to
attract and retain qualified individuals to serve on our Board or as executive officers. We are currently evaluating and monitoring developments with respect
to these rules, and we cannot predict or estimate the amount of additional costs we may incur or the timing of such costs.

When we cease to be an “emerging growth company” and when our independent registered public accounting firm is required to undertake an assessment of
our  internal  control  over  financial  reporting,  the  cost  of  our  compliance  with  Section  404  of  the  Sarbanes-Oxley  Act  will  correspondingly  increase.
Moreover, if we are not able to comply with the requirements of Section 404 applicable to us in a timely manner, or if we or our independent registered
public accounting firm identifies deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of
our stock could decline and we could be subject to sanctions or investigations by the SEC or other regulatory authorities, which would require additional
financial and management resources.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us difficult, limit attempts by our stockholders
to replace or remove our current management and adversely affect our stock price.

Provisions of our amended and restated certificate of incorporation and amended and restated bylaws may delay or discourage transactions involving an
actual or potential change in our 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. Therefore, these provisions could adversely affect the
price of our stock. Among other things, the certificate of incorporation and bylaws:

● permit the Board to issue up to 10 million shares of preferred stock, with any rights, preferences and privileges as they may designate;
● provide that the authorized number of directors may be changed only by resolution of our Board;
● provide  that  all  vacancies,  including  newly  created  directorships,  may,  except  as  otherwise  required  by  law,  be  filled  by  the  affirmative  vote  of  a

majority of directors then in office, even if less than a quorum;

● require that any action to be taken by our stockholders must be effected at a duly called annual or special meeting of stockholders and may not be taken

by written consent;

● create a staggered board of directors such that all members of our Board are not elected at one time;
● allow for the issuance of authorized but unissued shares of our capital stock without any further vote or action by our stockholders; and
● establish  advance  notice  requirements  for  nominations  for  election  to  the  Board  or  for  proposing  matters  that  can  be  acted  upon  at  stockholders’

meetings.

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, or the
DGCL, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any stockholder owning in
excess of 15% of our outstanding stock for a period of three years following the date on which the stockholder obtained such 15% equity interest in us.

The terms of our authorized preferred stock selected by our Board at any point could decrease the amount of earnings and assets available for distribution to
holders of our common stock or adversely affect the rights and powers, including voting rights, of holders of our common stock without any further vote or
action by the stockholders. As a result, the rights of holders of our common stock will be subject to, and may be adversely affected by, the rights of the
holders of any preferred stock that may be issued by us in the future, which could have the effect of decreasing the market price of our common stock.

90

 
 
 
 
 
 
 
 
 
 
Any provision of our certificate of incorporation or bylaws or Delaware corporate law that has the effect of delaying or deterring a change in control could
limit opportunities for our stockholders to receive a premium for their shares of common stock, and could also affect the price that investors are willing to
pay for our common stock.

Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for
certain  types  of  actions  and  proceedings  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.

Our amended and restated certificate of incorporation provides that, to the fullest extent permitted by law, the Court of Chancery of the State of Delaware
will  be  the  sole  and  exclusive  forum  for:  (i)  any  derivative  action  or  proceeding  brought  on  our  behalf;  (ii)  any  action  asserting  a  claim  of  breach  of  a
fiduciary  duty  owed  by  any  of  our  directors  or  officers  to  us  or  our  stockholders;  (iii)  any  action  asserting  a  claim  against  us  arising  pursuant  to  any
provision  of  the  DGCL,  our  amended  and  restated  certificate  of  incorporation  or  our  amended  and  restated  bylaws;  or  (d)  any  action  asserting  a  claim
against us governed by the internal affairs doctrine. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock is
deemed to have received notice of and consented to the foregoing provisions. This choice of forum provision may limit a stockholder’s ability to bring a
claim in a judicial forum that it finds more favorable for disputes with us or our directors or officers, which may discourage such lawsuits against us and our
directors or officers. Alternatively, if a court were to find this choice of forum provision inapplicable to, or unenforceable in respect of, one or more of the
specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely
affect our business, financial condition, prospects or results of operations.

Because we do not anticipate paying any cash dividends on our common stock in the foreseeable future, capital appreciation, if any, will be your sole
source of gain.

We have never declared or paid cash dividends on our equity securities. We currently intend to retain all of our future earnings, if any, to finance the growth
and development of our business. In addition, the terms of our existing A&R LSA with PWB preclude us, and the terms of any future debt agreement may
preclude us, from paying dividends. As a result, capital appreciation, if any, of our equity securities will likely be your sole source of gain for the
foreseeable future.

Market Information

PART II

Our common stock has been listed on the Nasdaq Capital Market under the symbol “LQDA” since July 26, 2018. Prior to that date, there was no established
public trading market for our common stock. As of March 9, 2020, the closing price of our common stock was $3.70 per share.

Holders

As of March 9, 2020, there were 89 record holders of our common stock, based upon information received from our transfer agent. However, this number
does not include beneficial owners whose shares were held of record by nominees or broker dealers. We estimate that there are more than 1,000 beneficial
owners of our common stock.

Dividend Policy

We have never paid any cash dividends on our capital stock. We anticipate that we will retain earnings, if any, to support operations and to finance the
growth and development of our business. In addition, the terms of our A&R LSA with PWB precludes us from paying cash dividends without the prior
written consent of PWB. Therefore, we do not expect to pay cash dividends for the foreseeable future.

Overview

We  are  a  late-stage  clinical  biopharmaceutical  company  focused  on  the  development  and  commercialization  of  novel  products  utilizing  our  proprietary
PRINT® technology to transform the lives of patients. PRINT is a particle engineering platform that enables precise production of uniform drug particles
designed  to  improve  the  safety,  efficacy  and  performance  of  a  wide  range  of  therapies.  We  are  currently  focused  on  the  development  of  two  product
candidates  for  which  we  hold  worldwide  commercial  rights:  LIQ861  for  the  treatment  of  pulmonary  arterial  hypertension,  or  PAH,  and  LIQ865  for  the
treatment  of  local  post-operative  pain.  LIQ861,  for  which  we  recently  filed  a  New  Drug  Application,  or  NDA,  with  the  FDA,  is  an  inhaled  dry  powder
formulation of treprostinil designed to improve the therapeutic profile of treprostinil by enhancing deep-lung delivery and achieving higher dose levels than
current inhaled therapies. We have applied our PRINT technology to enable us to deliver LIQ861 through a convenient, palm-sized dry powder inhaler, or
DPI. We have also applied our PRINT technology to our second product candidate, LIQ865, for which we have completed two Phase 1 clinical trials and
have initiated Phase 2-enabling toxicology studies. LIQ865 is designed to deliver sustained-release particles of bupivacaine, a non-opioid anesthetic, to treat
local  post-operative  pain  for  three  to  five  days  through  a  single  administration.  Additionally,  we  recently  initiated  a  pre-clinical  program  to  develop  an
inhaled product leveraging the benefits of our PRINT technology to engineer particles with precise, uniform, aerodynamic size and shape for deep lung
delivery.

Our  primary  objective  has  been  to  pursue  marketing  approval  of  LIQ861  and  commercialize  such  product  if  approved  by  FDA.  We  will  need  to  raise
substantial additional capital to continue our business operations, remain in compliance with the minimum cash requirement on our debt during and beyond
the third quarter of 2020, and to commercialize LIQ861, if approved. Such capital may not be available to us on a timely basis, on terms that are favorable
to us, or at all. Alternatively, in light of our current limited cash resources, the recent trading price of our common stock, outstanding debt and associated
minimum cash covenant, and based on a review of the status of our programs, resources and capabilities, we continue to explore a wide range of strategic
alternatives with the support of our financial advisor, Jefferies LLC, or Jefferies, that could maximize stockholder value. Our efforts have been and continue
to be focused primarily upon the potential formation of a partnership or a licensing transaction with respect to our lead program, LIQ861, for the treatment
of PAH. Strategic alternatives may also include the sale of some of our assets or proprietary technologies, or a potential merger or sale of the Company.
There can be no assurance that we will be able to enter into such a transaction or transactions on a timely basis, on terms that are favorable to us, or at all.

Product Pipeline

We are currently focused on the development of two product candidates for which we hold worldwide commercial rights: LIQ861 for the treatment of PAH
and LIQ865 for the treatment of local post-operative pain.

95

 
 
 
 
 
 
 
 
 
The following table summarizes our clinical-stage product candidates being developed using PRINT technology:

LIQ861          

In January 2020, we submitted an NDA to the FDA for LIQ861, our lead product candidate, as a potential treatment for patients with PAH. Treprostinil is a
synthetic analog of prostacyclin, a vasoactive mediator essential to normal lung function, which is deficient in patients with PAH. We believe that LIQ861
has the potential to improve the therapeutic profile of existing formulations of treprostinil by enhancing deep-lung delivery and achieving higher dose levels
than current inhaled therapies. We are developing LIQ861 under the 505(b)(2) regulatory pathway with Tyvaso as the reference listed drug, which allows us
to  rely  in  part  on  the  FDA’s  previous  findings  of  efficacy  and  safety  of  Tyvaso  and  the  active  ingredient  treprostinil,  which  has  been  approved  in  four
different products administered through the oral, inhaled and continuous infusion (parenteral) routes.

In August 2019, we completed an open-label Phase 3 clinical trial, INSPIRE, or Investigation of the Safety and Pharmacology of Dry Powder Inhalation of
Treprostinil,  for  LIQ861.  The  primary  objective  of  the  INSPIRE  study  was  to  evaluate  the  long-term  safety  and  tolerability  of  LIQ861.  The  study  was
designed to evaluate patients who have either been under stable treatment with Tyvaso (nebulizer-delivered treprostinil), for at least three months and were
transitioned to LIQ861 under the protocol, or Transition patients, or patients who had been under stable treatment with no more than two non-prostacyclin
oral  PAH  therapies  for  at  least  three  months  and  then  had  their  treatment  regimen  supplemented  with  LIQ861  under  the  protocol,  or  Add-On  patients.
Within the INSPIRE study, 18 Transition patients were evaluated in a one-directional crossover sub-study comparing bioavailability and pharmacokinetics,
or PK, of treprostinil following dosing of LIQ861 as compared with Tyvaso.

In March 2019, we reported that we had completed enrollment and met the primary endpoint, which was long-term safety and tolerability, in our INSPIRE
trial. LIQ861 was observed to be well-tolerated in 109 patients, with 101 patients (93%) completing at least two months of treatment. During the two-month
period, LIQ861 was evaluated at doses up to 159 mcg with no study-drug related serious adverse events. Dosing has exceeded 159 mcg in some patients
receiving drug beyond the Month 2 time point. We have not yet determined a maximum tolerated dose of LIQ861. We also reported fully enrolling our one-
directional crossover sub-study comparing bioavailability and PK of treprostinil as sub-study patients transitioned from Tyvaso to LIQ861.

In April 2019, we reported further data from these 109 patients in our INSPIRE trial on exploratory endpoints at two months of treatment that demonstrated
generally  favorable  results  with  respect  to  six-minute  walk  distance  and  quality  of  life  as  indicated  by  the  Minnesota  Living  with  Heart  Failure
Questionnaire, or MLHFQ. In May 2019, we reported further presentation of this data at the American Thoracic Society, or ATS, International Conference
2019.

In  June  2019,  we  reported  results  from  the  INSPIRE  study  indicating  that  the  79.5  mcg  dose  of  LIQ861  correlates  with  nine  breaths  of  Tyvaso,  the
maximum recommended label dose of Tyvaso. Analysis of the data from the PK sub-study in patients showed variability in systemic plasma levels of both
LIQ861 and Tyvaso, which is believed to be attributed to variation in severity of disease and has been seen in prior studies of treprostinil in patients. To
more accurately characterize the PK of LIQ861, we conducted two additional PK studies in healthy volunteers. In the first of these studies, we observed
unexpected variability in PK levels. Post-hoc analysis showed that plasma levels of treprostinil were tightly correlated to the LIQ861 dose delivered. Based
upon  additional  non-clinical  and  clinical  work,  we  believe  the  unexpected  variability  seen  in  this  healthy  volunteer  study  was  due  to  an  administration
technique unique to the conduct of the study in the Phase 1 setting. In August 2019, we completed a second PK study in healthy volunteers in which the
proper administration technique was followed. This study demonstrated significantly reduced variability, and we believe we have established comparative
bioavailability to the reference listed drug.

96

 
 
 
 
 
 
 
 
 
 
Final enrollment in the pivotal INSPIRE trial included 121 PAH patients to assess safety and tolerability through Month 2, the primary endpoint of the trial.
Of  the  121  patients  enrolled  in  the  study,  55  were  Transition  patients  and  66  were  Add-On  patients.  Add-On  patients  started  on  a  dose  of  26.5  mcg  of
LIQ861, with most (>80%) titrating to a 79.5 mcg dose or higher within the first two months of treatment. Consistent with preliminary data presented in the
second quarter of 2019, LIQ861 was observed to be well-tolerated and treatment-emergent adverse events were mostly mild to moderate in nature at Month
2  up  to  doses  of  159  mcg  of  LIQ861,  the  highest  dose  studied  at  Month  2.  Durability  of  therapy  with  LIQ861  appeared  to  be  favorable,  with  96%  of
Transition patients and 91% of Add-On patients remaining on study drug at the Month 2 timepoint.

Initial  analysis  of  the  exploratory  endpoints  from  the  INSPIRE  study  indicates  that  LIQ861  may  provide  functional  and  quality-of-life  benefits  to  PAH
patients in New York Heart Association, or NYHA, functional classes II and III. More than 90% of all patients who completed two months of treatment
maintained or improved their NYHA functional class. Additionally, we observed improvement in six-minute-walk-distance and quality of life as measured
by the MLHFQ in both patient groups.

We continued to treat patients who chose to remain on LIQ861 beyond the Month 2 timepoint of the primary endpoint. More than 80% of INSPIRE patients
remained on study drug at Month 4 with no significant changes in safety or tolerability observed compared to Month 2. At the completion of the INSPIRE
study, the patient with the longest duration of treatment had been on LIQ861 therapy for 18 months. To provide for continuity of treatment, patients from
INSPIRE were provided the opportunity to continue receiving treatment in an extension study, which is currently ongoing. In addition, we are enrolling
patients in a clinical study at certain investigational sites in Europe to characterize the hemodynamic dose-response relationship to LIQ861. We are also
considering conducting other clinical trials to generate additional data on LIQ861, including a clinical trial in pediatric patients. We also continue to conduct
development work in support of potential approval and commercialization of LIQ861, including label and patient-use assessments.

LIQ865

LIQ865  is  our  proprietary  injectable,  sustained-release  formulation  of  bupivacaine,  a  non-opioid  pain  medication.  We  have  engineered  the  size  and
composition of the LIQ865 PRINT particles to release bupivacaine over three to five days through a single administration for the management of local post-
operative  pain  after  a  surgical  procedure.  We  completed  a  Phase  1a  clinical  trial  of  LIQ865  in  Denmark  in  2017  and  a  Phase  1b  clinical  trial  in  the
United States in 2018. We initiated Phase 2-enabling toxicology studies in 2019 to assess LIQ865 in multiple non-clinical tissue models. Results from a
study to assess incision tensile strength after healing were acceptable and not statistically different from controls. A nonclinical study to examine soft tissue
healing was also completed, and the results were acceptable and comparable to vehicle-treated, saline-treated, and Marcaine-treated sites. We believe this
data supports progression to Phase 2 hernia repair studies. In a study to assess bone fracture healing, we observed dose-dependent delayed healing at the two
LIQ865 doses studied; however, there were no adverse effects noted on surrounding soft tissues. Additional studies have been initiated with lower doses of
LIQ865 to determine a no adverse effect level, or NOAEL, on bone healing. We will review the results from these toxicology studies, and if supportive, we
intend to initiate Phase 2 proof-of-concept clinical trials, subject to availability of capital and other factors, during 2021. We believe LIQ865, if successfully
developed and approved, has the potential to provide significantly longer local post-operative pain relief compared to currently marketed formulations of
bupivacaine.

97

 
 
 
 
 
 
 
Other

We believe that our PRINT technology can be applied to a wide range of therapeutic areas, molecule types and routes of administration. We are currently
focused on developing product candidates that we believe are eligible to be approved under the 505(b)(2) regulatory pathway, which can be capital efficient
and potentially enable a shorter time to approval, as it allows us to rely in part on existing knowledge of the safety and efficacy of the relevant reference
listed  drugs  to  support  our  applications  for  approval  in  the  United  States.  If  any  of  our  product  candidates  are  approved,  we  intend  to  conduct  initial
commercial manufacturing of drug product using in-house capabilities, and to outsource packaging and distribution to third parties. Where appropriate, we
may  also  transition  the  commercial  manufacture  of  our  drug  product  to  third  parties.  In  addition  to  developing  our  two  product  candidates,  we  have
provided specific field-limited licenses to our PRINT technology to pharmaceutical companies seeking to develop their own potential drugs and biological
therapies.

Financial Overview

We have not generated any revenue to date from the sale of pharmaceutical products, and we have historically financed our operations in large part with an
aggregate of $235.3 million of gross proceeds from sales of our capital stock and convertible promissory notes, $16.0 million in term loans from a bank and
a $2.1 million loan from The University of North Carolina at Chapel Hill, or UNC. We do not expect to generate significant product revenue unless and
until we obtain marketing approval for and commercialize LIQ861, LIQ865 or one of our other future product candidates.

Since  our  inception,  we  have  incurred  significant  operating  losses.  Our  net  loss  was  $47.6  million,  $53.1  million  and  $29.2  million  for  the  years  ended
December  31,  2019,  2018  and  2017,  respectively.    As  of  December  31,  2019,  we  had  an  accumulated  deficit  of  $215.2  million.  We  expect  to  incur
significant expenses and operating losses for the foreseeable future as we advance our product candidates through clinical trials, seek regulatory approval
and  pursue  commercialization  of  any  approved  product  candidates.  In  addition,  if  we  obtain  marketing  approval  for  any  of  our  product  candidates,  we
expect  to  incur  significant  commercialization  expenses  related  to  product  manufacturing,  marketing,  sales  and  distribution.  In  addition,  we  may  incur
expenses in connection with the in-license or acquisition of additional product candidates.

As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until such time as we can
generate  significant  revenue  from  product  sales,  if  ever,  we  expect  to  finance  our  operations  through  the  sale  of  equity,  debt  financings  or  other  capital
sources, including potential collaborations with other companies or other strategic transactions. We may be unable to raise additional funds or enter into
such other agreements or arrangements when needed, on favorable terms, or at all. If we fail to raise capital or enter into such agreements as, and when,
needed, we may have to significantly delay, scale back or discontinue the development and commercialization of one or more of our product candidates or
delay our pursuit of potential in-licenses or acquisitions.

As  of  December  31,  2019,  we  had  $55.8  million  of  cash.  We  believe  that  our  existing  cash  will  enable  us  to  fund  our  operating  expenses  and  capital
expenditure requirements, make payments of interest and principal on our term loan facility with Pacific Western Bank, or PWB, and remain in compliance
with the minimum cash covenant of $8.5 million pursuant to this term loan facility, through August 2020. We have based these estimates on assumptions
that may prove to be wrong, and we could utilize our available capital resources sooner than we expect. See “Liquidity and Capital Resources.”

As of December 31, 2019, our commitments for capital expenditures consisted of a remaining payment obligation of approximately $360,000 related to the
build-out of our corporate headquarters which was completed in 2019.  As of December 31, 2019, we do not have any other material capital expenditure
commitments.

98

 
 
 
 
 
 
 
 
 
 
Going Concern

Our financial statements have been prepared assuming we will continue as a going concern, which contemplates the realization of assets and the settlement
of  liabilities  and  commitments  in  the  normal  course  of  business.  Our  operations  have  consisted  primarily  of  developing  our  technology,  developing
products,  prosecuting  our  intellectual  property  and  securing  financing.  We  have  incurred  recurring  losses  and  cash  outflows  from  operations,  have  an
accumulated deficit, and have debt principal payments that commenced in the first quarter of 2020. We expect to continue to incur losses in the foreseeable
future and will require additional financial resources to continue to advance our products and intellectual property, in addition to repaying our maturing debt
and other obligations. These circumstances raise substantial doubt about our ability to continue as a going concern.

Management’s plans with regard to this matter include continuing attempts to obtain additional financing to sustain our operations.  However, there is no
assurance  that  we  will  be  successful  in  obtaining  sufficient  financing  on  terms  acceptable  to  us,  and  the  failure  to  obtain  sufficient  funds  on  acceptable
terms,  when  needed,  could  have  a  material  adverse  effect  on  our  business,  results  of  operations  and  financial  condition.    If  sufficient  financings  are  not
obtained, this may necessitate other actions by us.  Alternatively, in light of our current limited cash resources, the recent trading price of our common stock,
outstanding debt and associated minimum cash covenant, and based on a review of the status of our programs, resources and capabilities, we continue to
explore a wide range of strategic alternatives with the support of our financial advisor, Jefferies LLC, that could maximize stockholder value. Our efforts
have been and continue to be focused primarily upon the potential formation of a partnership or a licensing transaction with respect to our lead program,
LIQ861, for the treatment of PAH. Strategic alternatives may also include the sale of some of our assets or proprietary technologies, or a potential merger or
sale of our Company. Our plans with regard to this matter include continuing attempts to obtain additional financing to sustain our operations. However,
there  is  no  assurance  that  we  will  be  successful  in  obtaining  sufficient  financing  on  terms  acceptable  to  us,  and  the  failure  to  obtain  sufficient  funds  on
acceptable terms, when needed, could have a material adverse effect on our business, results of operations and financial condition. If sufficient financings
are not obtained, this may necessitate other actions by us. The financial statements do not include any adjustments that might result from the outcome of this
uncertainty.

Our Collaborations

Our  only  revenue,  which  has  been  derived  from  collaborating  with,  and  licensing  our  proprietary  PRINT  technology  to,  pharmaceutical  companies,
amounted to $8.1 and $2.7 million for the years ended December 31, 2019 and 2018, respectively. GlaxoSmithKline plc, or GSK, accounted for $8.1 and
$0.4 million of our revenue for the years ended December 31, 2019 and 2018, respectively, or 100% and 15%  respectively, of our total revenue during these
years.   We  have  received  upfront  fees  for  technology  access,  milestone  payments,  and  fees  to  develop  drug  products  through  research  and  development
services, such as particle formulation and manufacturing.

In  addition  to  advancing  our  own  product  candidates,  LIQ861  and  LIQ865,  we  have  collaborated,  and  may  consider  collaborating,  with  pharmaceutical
companies to develop their own product candidates across a wide range of therapeutic areas, molecule types and routes of administration, leveraging our
PRINT  technology.  These  collaborations  are  intended  to  help  advance  new  PRINT  capabilities  and  build  upon  our  competitive  advantage  in  the
pharmaceutical industry, while adding to our intellectual property portfolio.

We  have  exclusively  licensed  our  PRINT  technology  to  (i)  GSK  for  applications  broadly  across  inhaled  delivery  of  their  small  molecule  and  biologic
chemical entities, although we retained the ability to develop LIQ861; and (ii) Aerie Pharmaceuticals, Inc., which in 2017 acquired most of the assets of
Envisia  Therapeutics,  Inc.,  an  entity  which  we  formed  in  2013,  for  broad  usage  in  the  design  and  commercialization  of  small  molecule  and  biologic
ophthalmic therapies.

GlaxoSmithKline

Previously,  we  had  collaborated  with  GSK  on  the  use  of  our  PRINT  technology  in  respiratory  disease.  In  June  2012,  we  entered  into  an  Inhaled
Collaboration and Option Agreement, or the GSK ICO Agreement, with GSK to collaborate on research regarding the application of our PRINT technology
to specified inhaled therapies. Pursuant to the GSK ICO Agreement, we granted GSK exclusive options and licenses to further develop and commercialize
such inhaled therapies using our PRINT technology. In partial consideration of the rights granted to GSK under the GSK ICO Agreement, we received a
one-time up-front payment of $4.0 million.

99

 
 
 
 
 
 
 
 
 
 
 
In  September  2015,  GSK  exercised  its  option  to  obtain  an  exclusive,  worldwide  license  to  certain  of  our  know-how  and  patents  relating  to  our  PRINT
technology, for the purpose of, among others, preclinical studies of inhaled therapeutics developed, manufactured or otherwise produced using our PRINT
technology.  In  connection  with  the  grant  of  this  license,  we  received  a  one-time  option  exercise  fee  of  $15.0  million.  Under  the  terms  of  the  GSK  ICO
Agreement, we were also entitled to continued research and development funding and certain milestone payments aggregating up to $158 million upon the
achievement of specified events for new non-rescue therapeutic products. Rescue therapeutic products are therapeutics that GSK develops with our PRINT
technology that had previously been discontinued from development. We are also entitled to tiered royalties on the worldwide sales of the licensed products
at percentages ranging from the mid-single digits to low-single digits depending on the total number of products developed and other royalty step-down
events  with  a  fixed  low-single  digit  royalty  floor.  In  February  2016,  we  received  a  $3.0  million  payment  from  GSK  upon  the  achievement  of  a  clinical
development milestone related to the development of an inhaled antiviral for viral exacerbations in chronic obstructive pulmonary disease. However, in July
2018, GSK notified us of its plans to discontinue development of this compound after completion of the related Phase 1 clinical trial.

GSK has the right to terminate the GSK ICO Agreement in its entirety or on a product-by-product basis upon a specified period of prior written notice.
Upon termination of the GSK ICO Agreement, each party will continue to have the right to practice and/or license its interest in any know-how developed
during the collaboration without seeking the consent of, or accounting to, the other party.

In  June  2019,  we  and  GSK  executed  the  third  amendment  to  the  collaboration  agreement  providing  us  with  rights  to  develop  and  commercialize  three
specified  molecular  entities  for  application  in  inhaled  programs  using  our  PRINT  technology  at  our  sole  expense.  This  amendment  also  provided  a
mechanism for us to acquire rights to develop and commercialize further molecular entities for inhaled applications. New inhaled programs developed under
this amendment would carry milestone and royalty payments due to GSK upon initiation of Phase 3 studies and subsequent commercialization, respectively.
This  amendment,  among  other  factors,  including  the  lack  of  continued  performance  anticipated  by  us  and  GSK  under  the  original  agreement,  led  us  to
believe that no further research and development services will be provided to GSK under the collaboration agreement. Accordingly, in January 2020, we
notified GSK of our intent to terminate the GSK ICO Agreement based upon GSK's lack of performance under the agreement, which we believe constitutes
a  material  breach  of  the  agreement.  In  February  2020,  we  received  a  letter  from  GSK  disputing  our  basis  for  termination.  The  parties  are  currently
attempting to resolve the dispute pursuant to the terms of the GSK ICO Agreement.

Components of Statements of Operations

Revenue

Our revenue is primarily derived from collaborating and licensing our proprietary PRINT technology to pharmaceutical companies. In the future, we also
expect to derive our revenue from our own pharmaceutical products. Up until the fourth quarter of 2018, we managed, reported and evaluated our business
in the following two segments: Pharmaceutical Products and Partnering and Licensing. These reportable operating segments were determined in accordance
with  our  internal  management  structure,  which  was  organized  based  on  operating  activities,  the  manner  in  which  we  organized  segments  for  making
operating decisions and assessing performance and the availability of separate financial results.

In the fourth quarter of 2018, due to significantly diminished activities pursuant to collaborations, we changed the way we manage and operate the reporting
entity and modified our information system to produce financial information for the chief operating decision maker, or CODM, to support the new structure.
The  changes  required  us  to  revise  our  segment  reporting.  Management  reorganized  our  operations  and  reporting  structure  and  began  to  manage  our
operations  under  our  new  segment  structure,  resulting  in  a  single  reportable  segment.  The  financial  statements  were  adjusted  to  reflect  this  change  in
segment reporting for all periods presented.

All long-lived assets are domiciled and all revenues were earned within the United States.

Cost of Sales

Cost of sales consists of the amortization of license fees owed to UNC upon our receipt of licensing revenues. See “Business — Our Collaboration and
Licensing  Agreements  —  The  University  of  North  Carolina  at  Chapel  Hill”  for  further  details.  We  amortize  the  license  fees  owed  to  UNC  in  a  manner
consistent with our recognition of the related revenue.

Research and Development Expenses

Research and development expense consists of expenses incurred in connection with the development of our product candidates. We expense research and
development costs as incurred. These expenses include:

● expenses incurred under agreements with CROs as well as investigative sites and consultants that conduct our clinical trials and preclinical

studies;

● manufacturing process development and scale-up expenses and the cost of acquiring and manufacturing preclinical and clinical trial materials

and commercial materials, including manufacturing validation batches;

● outsourced professional scientific development services;

● employee-related  expenses,  which  include  salaries,  benefits  and  stock-based  compensation  for  personnel  in  research  and  development

functions;

● expenses relating to regulatory activities, including filing fees paid to regulatory agencies;

● laboratory materials and supplies used to support our research activities; and

● allocated expenses for utilities and other facility-related costs.

Research  and  development  activities  are  central  to  our  business  model.  Product  candidates  in  later  stages  of  clinical  development  generally  have  higher
development  costs  than  those  in  earlier  stages  of  clinical  development,  primarily  due  to  the  increased  size  and  duration  of  later-stage  clinical  trials.  We
expect our research and development expenses to increase significantly over the next several years as we increase personnel costs, including stock-based
compensation, conduct our ongoing clinical trial and other development work for LIQ861, continue the development of LIQ865, conduct additional clinical
trials, continue manufacturing process development and scale up and prepare for regulatory filings for our product candidates and regulatory inspection of
facilities utilizing our PRINT manufacturing process. The successful development of our product candidates is highly uncertain. At this time, we cannot
reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the remainder of the development of, or when, if
ever,  material  net  cash  inflows  may  commence  from  any  of  our  product  candidates.  This  uncertainty  is  due  to  the  numerous  risks  and  uncertainties
associated with the duration and cost of clinical trials, which vary significantly over the life of a project as a result of many factors, including:

● the number of clinical sites included in the trials;

● the length of time required to enroll suitable patients;

● the number of patients that ultimately participate in the trials;

● the number of doses patients receive;

● the duration of patient follow-up; and

● the results of our clinical trials.

Our  expenditures  are  subject  to  additional  uncertainties,  including  the  terms  and  timing  of  regulatory  approvals,  and  the  expense  of  filing,  prosecuting,
defending  and  enforcing  any  patent  claims  or  other  intellectual  property  rights.  We  may  never  succeed  in  achieving  regulatory  approval  for  any  of  our
product candidates. We may obtain unexpected results from our clinical trials. We may elect to discontinue, delay or modify clinical trials of some product
candidates  or  focus  on  others.  A  change  in  the  outcome  of  any  of  these  variables  with  respect  to  the  development  of  a  product  candidate  could  mean  a
significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or other regulatory authorities
were to require us to conduct clinical trials beyond those that we currently anticipate, or if we experience significant delays in enrollment in any of our
clinical trials, or our ability to manufacture and supply product, we could be required to expend significant additional financial resources and time on the
completion of clinical development. Drug commercialization will take several years and millions of dollars in development costs.

General and Administrative Expenses

General and administrative expenses consist principally of salaries and related costs for personnel in executive, administrative, finance and legal functions,
including  stock-based  compensation,  travel  expenses  and  recruiting  expenses.  Other  general  and  administrative  expenses  include  facility  related  costs,
patent filing and prosecution costs and professional fees for marketing, legal, auditing and tax services and insurance costs.

We  anticipate  that  our  general  and  administrative  expenses  will  increase  as  a  result  of  increased  personnel  costs,  including  stock-based  compensation,
expanded infrastructure and higher consulting, legal and tax-related services associated with maintaining compliance with stock exchange listing and SEC
requirements, accounting and investor relations costs, and director and officer insurance premiums associated with being a public company. Additionally,
when we believe a regulatory approval of a product candidate appears likely, we anticipate an increase in payroll and expense as a result of our preparation
for commercial operations, especially as it relates to the sales and marketing of our product candidate.

Other Income (Expense)

Other income (expense) is comprised primarily of interest income and expense. Interest income consists of interest earned on our cash deposits. Interest
expense  consists  of  interest  charges  on  leases  and  debt.  These  charges  include  monthly  recurring  interest  on  such  obligations  in  addition  to  non-cash
charges. Non-cash charges include the expensing of debt issuance costs and amortization of discounts on long-term debt to interest expense.

Critical Accounting Estimates

This  management’s  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  is  based  on  our  financial  statements,  which  have  been
prepared in accordance with generally accepted accounting principles in the United States, or GAAP. The preparation of these financial statements requires
us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities
in our financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those for revenue recognition and accrued research
and  development  expenses.  We  base  our  estimates  on  historical  experience,  known  trends  and  events  and  various  other  factors  that  we  believe  to  be
reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not
readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in the notes to our financial statements, we believe the following accounting policies
to be the most critical to the judgments and estimates used in the preparation of our financial statements.

Revenue Recognition

We derive our revenues primarily from licensing our proprietary PRINT technology and from performing research and development services. Revenues are
recognized as services are performed in an amount that reflects the consideration we expect to be entitled to in exchange for those services and technology.

Our research, development and licensing agreements provide for multiple promised goods and services to be provided by us and include a license to our
technology  in  a  particular  field  of  study,  participation  in  collaboration  committees,  performance  of  certain  research  and  development  services  and
obligations for certain manufacturing services.

102

 
 
 
 
 
 
 
 
 
 
 
 
 
The transaction price for these contracts includes non-refundable fees and fees for research and development services. Non-refundable upfront fees, which
may include, for example, an initial payment upon effectiveness of the contractual relationship or payment to secure a right for a future license, are recorded
as deferred revenue and recognized into revenue over time as we provide the research services under the contract required to advance the products to the
point where we are able to transfer control of the licensed technology to the customer, or the Technology Transfer. The contract consideration may also
include  additional  non-refundable  payments  due  to  us  based  on  the  achievement  of  research,  development,  regulatory  or  commercialization  milestone
events. In agreements involving multiple goods or services promised to be transferred to customers, we must assess, at the inception of the contract, whether
each  promise  represents  a  separate  performance  obligation  (i.e.,  is  “distinct”),  or  whether  such  promises  should  be  combined  as  a  single  performance
obligation.  As  these  goods  and  services  are  considered  to  be  highly  interrelated,  they  may  be  considered  to  represent  a  single,  combined  performance
obligation. We include an estimate of the probable amount of milestone payments to which we will be entitled in the transaction price. The estimate requires
evaluation of factors which are outside of our control and significantly limit our ability to achieve the remaining milestone payments. Therefore, we have
not included any future milestone payments in the transaction price allocated to research, development and licensing agreements as of December 31, 2019.
We  revise  the  transaction  price  to  include  milestone  payments  once  the  specific  milestone  achievement  is  not  considered  to  be  subject  to  a  significant
reversal  of  revenue.  At  that  time,  the  estimated  transaction  price  is  adjusted  and  a  cumulative  catch-up  adjustment  is  recorded  to  adjust  the  amount  of
revenue to be recognized from the license inception to the date the milestone was deemed probable of achievement. The milestone is included with other
non-refundable upfront fees and recognized into revenue over time as we continue to provide services under the contract through our Technology Transfer.
The amount of revenue recognized is based on the proportion of total research services performed to date to the expected services to be provided through
the Technology Transfer.

The estimate of the research services to be provided through the Technology Transfer requires significant judgment to evaluate assumptions regarding the
level of effort required for us to have performed sufficient obligations for the customer to be able to utilize the licensed technology without requiring further
services  from  us.  If  the  estimated  level  of  effort  changes,  the  remaining  deferred  revenue  is  recognized  over  the  revised  period  in  which  the  expected
research services and Technology Transfer are required. Changes in estimates occur for a variety of reasons, including but not limited to (i) research and
development acceleration or delays, (ii) customer prioritization of research projects, or (iii) results of research and development activities. We recognize the
consideration we are entitled to receive for research and development services, which are primarily billed quarterly in arrears on a time and materials basis,
as  the  services  are  performed  (under  a  proportional  performance  model)  and  collection  is  reasonably  assured.  Additionally,  any  upfront  or  development
milestone payments received are also recognized as revenue, over time, under this same proportional performance model.

Royalties related to product sales will be recognized as revenue when the sale occurs since payments relate directly to products that will have been fully
developed and for which we will have satisfied all performance obligations.

Accrued Research and Development Expenses

When  preparing  our  financial  statements,  we  are  required  to  estimate  our  research  and  development  expenses.  This  process  involves  reviewing  open
contracts and communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service performed
and  the  associated  cost  incurred  for  the  service  when  we  have  not  yet  been  invoiced  or  otherwise  notified  of  actual  cost.  Payments  under  some  of  the
contracts we have with parties depend on factors, such as successful enrollment of certain numbers of patients, site initiation and the completion of clinical
trial milestones. When accruing clinical expenses, we estimate the time period over which services will be performed and the level of effort to be expended
in each period. If possible, we obtain information regarding unbilled services directly from our service providers. However, we may be required to estimate
the cost of these services based only on information available to us. If we underestimate or overestimate the cost associated with a trial or service at a given
point in time, adjustments to research and development expenses may be necessary in future periods. Historically, our estimated research and development
expenses have approximated actual expenses incurred.

103

 
 
 
 
 
 
 
Examples of estimated accrued expenses include:

•

•

fees paid to CROs in connection with clinical trials; and

fees paid to investigative sites in connection with clinical trials.

If the actual timing of the performance of services or the level of effort varies from our estimate, we will adjust the accrual accordingly. If we do not identify
costs that we have begun to incur or if we underestimate or overestimate the level of services performed or the costs of these services, our actual expenses
could differ from our estimates. We do not anticipate the future settlement of existing accruals to differ materially from our estimates.

Revenues were $8.1 million for the year ended December 31, 2019, compared with $2.7 million for the year ended December 31, 2018. The increase of $5.4
million,  or  198.2%,  was  due  to  the  full  recognition  in  the  second  quarter  of  2019  of  $8.1  million  of  deferred  revenue  from  the  GSK  ICO  Agreement
resulting from the Third Amendment that was entered into in June 2019.

Cost of Sales

Our cost of sales was $0.8 million for the year ended December 31, 2019, compared with $0.1 million for the year ended December 31, 2018. The increase
of $0.7 million was due to the increase in revenues. Cost of sales represents sub-licensing fees paid to UNC when licensing revenue is recognized from the
use of the intellectual property that we in-licensed from UNC.

Research and Development Expenses

Research  and  development  expenses  were  $40.5  million  for  the  year  ended  December  31,  2019,  compared  with  $28.7  million  for  the  year
ended December 31, 2018. The increase of $11.8 million, or 41.1%, was primarily due to the ongoing clinical development of LIQ861 which commenced in
late December 2017. Research and development expenses for the year ended December 31, 2019 consisted of $31.7 million and $4.0 million attributable to
our development of LIQ861 and LIQ865, respectively, and $4.8 million from general research and development that was not directly related to LIQ861 and
LIQ865. This compares with $19.6 and $0.7 million which were attributable to our development of LIQ861 and LIQ865, respectively, and $8.4 million
from general research and development that was not directly related to either LIQ861 or LIQ865 during the year ended December 31, 2018.

General and Administrative Expenses

General  and  administrative  expenses  were  $13.6  million  for  the  year  ended  December  31,  2019,  compared  with  $8.8  million  for  the  year
ended December 31, 2018. The increase of $4.8 million, or 55.3% during the year ended December 31, 2019 compared with 2018 was due to an increase in
commercialization efforts expenses of $2.4 million, an increase in directors and officers insurance of $0.8 million, an increase in stock-based compensation
of $0.7 million, an increase in recruiting fees of $0.5 million, an increase in consulting fees of $0.2 million and an increase in legal fees of $0.2 million.
General  and  administrative  expenses  consist  primarily  of  personnel  expenses,  including  stock-based  compensation,  as  well  as  directors  and  officers
insurance, and fees for audit, legal, consulting and other service fees.

Other Income (Expense)

Interest income was $0.6 million for the year ended December 31, 2019, compared with $0.3 million for the year ended December 31, 2018. The increase of
$0.3 million was due to an increase in cash balances held in interest-bearing accounts in 2019 compared with 2018.

Interest expense was $1.4 million for the year ended December 31, 2019, compared with $19.0 million for the year ended December 31, 2018. The decrease
in interest expense of $17.6 million, or 92.8%, was primarily due to lower levels of debt during the year ended December 31, 2019 and the conversion of
$27.4 million of convertible notes into shares of Series D preferred stock in February 2018.

During 2018, our debt refinancing resulted in a non-cash gain of $0.1 million in accordance with ASC 470-50, Debt – Modifications and Extinguishments.

Derivative and warrant fair value adjustments resulted in income of $0 for the year ended December 31, 2019, compared with income of $0.3 million for the
year  ended  December  31,  2018.  The  decrease  of  $0.3  million  was  due  to  the  conversion  of  the  warrants  for  convertible  preferred  stock  to  warrants  for
common stock at the time of the initial public offering during the year ended December 31, 2018.

Liquidity and Capital Resources

We have financed our growth and operations through a combination of funds generated from our licensing revenues, the issuance of convertible preferred
stock and common stock, capital leases, bank borrowings and the issuance of convertible notes. Our principal uses of cash have been for working capital
requirements  and  capital  expenditures.  As  of  December  31,  2019,  we  had  a  cash  balance  of  $55.8  million,  stockholders’  equity  of  $34.9  million  and  an
accumulated deficit of $215.2 million.

105

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In  July  2018,  we  closed  the  initial  public  offering  of  4,833,099  shares  of  common  stock  at  a  public  offering  price  of  $11.00  per  share,  including  the
underwriters’  partial  exercise  of  their  over-allotment  option  in  connection  therewith,  which  resulted  in  aggregate  net  proceeds  of  $47.3  million,  after
underwriting discounts and the payment of other offering expenses.

In March 2019, we closed an underwritten follow-on offering of 3,000,000 shares of our common stock at a public offering price of $11.50 per share. The
gross  proceeds  from  the  offering  were  $34.5  million  and  net  proceeds  were  $31.8  million,  after  deducting  underwriting  discounts  and  commissions  and
other offering expenses.

In August 2019, we entered into a sales agreement, or the ATM Agreement, with Jefferies to issue and sell shares of our common stock, having an aggregate
offering price of up to $40.0 million, from time to time during the term of the ATM Agreement, through an “at-the-market” equity offering program at our
sole discretion, under which Jefferies will act as our agent and/or principal. We will pay Jefferies a commission up to 3.0% of the gross proceeds of any
common stock sold through Jefferies under the ATM Agreement. During the year ended December 31, 2019, we sold 2,409,356 shares of common stock for
gross  proceeds  of  $8.4  million  and  net  proceeds  were  $8.1  million,  after  deducting  underwriting  discounts  and  other  offering  expenses  under  the  ATM
Agreement.

On December 23, 2019, we entered into a Common Stock Purchase Agreement, or the Purchase Agreement, with certain institutional accredited investors,
or the Purchasers, for the sale by us in a private placement, or the Private Placement, of an aggregate of 7,164,534 shares, or the Private Placement Shares,
of our common stock, at a purchase price of $3.13 per Private Placement Share. The closing of the Private Placement occurred on December 27, 2019. The
gross  proceeds  from  the  sale  of  the  Private  Placement  Shares  were  $22.4  million  and  net  proceeds  were  $21.0  million,  after  placement  agent  fees  and
offering expenses.

Prior to our initial public offering, in a series of closings from January 2017 through November 2017, we issued and sold an aggregate of $27.4 million of
unsecured subordinated convertible promissory notes, each accruing simple interest at a rate of 8.0% per annum. Also prior to our initial public offering, in
February 2018, we issued and sold an aggregate of 91,147,482 shares of Series D preferred stock at a price per share equal to $0.59808. Of the 31 investors
that participated in the financing, 10 investors purchased an aggregate of 42,863,825 shares of Series D preferred stock for an aggregate purchase price of
$25.6  million  and  26  holders  of  outstanding  convertible  notes,  in  the  aggregate  amount  of  $28.9  million,  converted  their  notes  into  an  aggregate  of
48,283,657 shares of Series D preferred stock.

In addition to raising equity capital, we have financed a portion of our working capital through debt instruments. We maintained a $10.0 million term loan
facility with PWB for working capital purposes pursuant to a loan and security agreement, or the LSA. Immediately prior to entry into the A&R LSA (as
defined below), we had fully utilized our $10.0 million term loan facility with PWB with a remaining outstanding balance of $8.0 million. The facility was
secured by all of our assets other than intellectual property. We could not encumber our intellectual property without the consent of PWB. The outstanding
principal amount under the loan facility bore interest at 5.0% per annum. Of the then-current amount outstanding, the loan was to mature with respect to
$3.0 million in January 2020, with the remainder being due and payable in October 2020. Beginning in August 2018, the term loan would have required
equal monthly payments of principal plus interest each month thereafter until amortized and paid in full. We have, in the past, breached multiple covenants
in our LSA related to cash levels and reporting requirements. PWB provided waivers in relation to all such prior breaches.

In October 2018, we and PWB entered into an Amended and Restated Loan and Security Agreement, or the A&R LSA, in which we received an initial
tranche  of  $11.0  million  to  extinguish  our  then-current  debt  of  $8.0  million  under  the  LSA,  repay  in  full  the  outstanding  indebtedness  under  the  UNC
Promissory Note (as defined below) and to utilize for general corporate purposes. The indebtedness under the A&R LSA bears interest at the greater of the
Prime rate or 5% and has a four-year term and maturity. The A&R LSA provided for access to a second tranche of up to $5.0 million, the full amount of
which we drew in June 2019. The second tranche became accessible as a result of the full enrollment of the Company’s LIQ861 INSPIRE clinical trial,
without  observing  any  materially  adverse  data  through  the  two  week  endpoint.  Both  tranches  required  payments  of  interest-only  through  December  31,
2019. The A&R LSA carries a one-time success fee of $375,000 and a prepayment penalty of 1% if the drawn tranche is prepaid prior to October 27, 2020.
The success fee was triggered in December 2019 by the sale of common stock and this was recorded as interest expense of $375,000 during the year ended
December 2019. The minimum cash covenant is $8.5 million. In May 2019, we and PWB entered into an amendment to the A&R LSA to, among others,
amend  our  negative  covenant  related  to  capitalized  expenditures  to  increase  the  aggregate  amount  of  capitalized  expenditures  we  are  permitted  to  make
without PWB’s prior written consent during the fiscal year ending December 31, 2019 from $1.25 million to $2.5 million.

106

 
 
 
 
 
 
 
 
 
The A&R LSA with PWB, as amended, contains restrictions that limit our flexibility in operating our business. We may not, among other things, without
the prior written consent of PWB, (a) pay any dividends or make any other distribution or payment on account of or in redemption, retirement or purchase
of any capital stock except in certain prescribed circumstances, (b) create, incur, assume, guarantee or be or remain liable with respect to any indebtedness
except certain permitted indebtedness or prepay any indebtedness, (c) replace or suffer the departure, as defined, of our Chief Executive Officer or Chief
Financial Officer without delivering written notification to PWB within ten days of such change or (d) suffer a change on our Board which results in the
failure of at least one partner of Canaan Partners or their respective affiliates to serve as a voting member, in each case without having used best efforts to
deliver at least 15 days’ prior written notification to PWB.  PWB maintains a blanket lien on all assets excluding intellectual property, for which it has been
provided a negative pledge.

During most of the year ended December 31, 2018, we had outstanding a promissory note to UNC, or the UNC Promissory Note. The UNC Promissory
Note was unsecured and bore interest at a rate equal to one-year LIBOR plus 3%, compounded annually. The UNC Promissory Note was due and payable in
full  on  December  31,  2018.  Following  the  completion  of  the  initial  public  offering  of  our  common  stock  in  July  2018,  we  made  a  payment  to  UNC  of
$600,000 in August 2018. We repaid the entire balance outstanding under the UNC Promissory Note, plus accrued interest pursuant to the closing of the
A&R LSA with PWB in October 2018.

ended December 31, 2018. The increase was mainly due to an increase from our research and development expenditures and general and administrative
costs  during  the  year  ended  December  31,  2019  compared  with  2018.  For  the  year  ended  December  31,  2019,  the  net  cash  used  in  operating  activities
was $48.3 million, which was comprised of operating cash outflows before working capital changes of $40.8 million and net working capital outflows of
$7.5 million.

Investing Activities

Net  cash  used  in  investing  activities  increased  $1.0  million  to  $1.9  million  for  the  year  ended  December  31,  2019  from  $0.9  million  for  the  year
ended December 31, 2018. The increase was due to a higher level of purchases of property, plant and equipment.

Financing activities

Net cash provided by financing activities decreased $2.4 million to $66.4 million for the year ended December 31, 2019 from $68.8 million for the year
ended December 31, 2018. This decrease was primarily due to net proceeds from follow-on offerings of common stock of $63.0 million and the $5.0 million
draw under the A&R LSA during the year ended December 31, 2019, compared with the sale of Series D preferred stock of $25.1 million and the sale of
our common stock for net proceeds of $47.3 million in our initial public offering, during the year ended December 31, 2018.

Funding Requirements

We plan to focus in the near-term on the development, regulatory approval and potential commercialization of LIQ861 and LIQ865. We anticipate we will
incur  net  losses  for  the  next  several  years  as  we  complete  clinical  development  of  these  product  candidates  and  continue  research  and  development  of
additional  product  candidates.  In  addition,  we  plan  to  continue  to  invest  in  discovery  efforts  to  explore  additional  product  candidates,  potentially  build
commercial capabilities and expand our corporate infrastructure. We may not be able to complete the development and initiate commercialization of these
programs if, among others, our clinical trials are not successful or if the FDA does not approve our product candidates arising out of our current clinical
trials when we expect, or at all.

Our primary uses of capital are, and we expect will continue to be, compensation and related expenses, clinical costs, manufacturing process development,
external research and development services, laboratory and related supplies, legal and other regulatory expenses, administrative and overhead costs and debt
service. Our future funding requirements will be heavily determined by the resources needed to support development of our product candidates.

As a publicly traded company we incur significant legal, accounting and other expenses that we were not required to incur as a private company. In addition,
the Sarbanes-Oxley Act, as well as rules adopted by the SEC and Nasdaq Stock Market LLC, or Nasdaq, require public companies to implement specified
corporate governance practices that previously were inapplicable to us as a private company. We expect these rules and regulations will increase our legal
and financial compliance costs and will make some activities more time-consuming and costly.

We believe that our current cash balance will enable us to fund our operating expenses and capital expenditure requirements into the fourth quarter of 2020.
However, there is a minimum cash requirement in conjunction with our term loan facility with PWB of $8.5 million which could be reached by the end of
the third quarter of 2020 unless additional funds are raised. We have based these estimates on assumptions that may prove to be wrong, and we could utilize
our available capital resources sooner than we expect. We expect that we will require additional capital to complete NDA regulatory review of LIQ861 and
commercialize our product candidates, if we receive regulatory approval, and to pursue in-licenses or acquisitions of other product candidates. If we receive
regulatory approval for LIQ861 or LIQ865, we expect to incur significant commercialization expenses related to product manufacturing, sales, marketing
and distribution, depending on where we choose to commercialize. Additional funds may not be available on a timely basis, on favorable terms, or at all,
and such funds, if raised, may not be sufficient to enable us to continue to implement our long-term business strategy. If we are unable to raise sufficient
additional capital, we may need to substantially curtail our planned operations and the pursuit of our growth strategy.

We  may  raise  additional  capital  through  licensing  activities,  other  business  arrangements  or  the  sale  of  equity  or  convertible  debt  securities.  In  such  an
event, your ownership will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a
holder of our common stock.

Because  of  the  numerous  risks  and  uncertainties  associated  with  research,  development  and  commercialization  of  pharmaceuticals,  we  are  unable  to
estimate the exact amount of our working capital requirements. Our future funding requirements will depend on many factors, including:

● the number and characteristics of the product candidates we pursue;

● the scope, progress, results and costs of researching and developing our product candidates, and conducting preclinical studies and clinical trials;

108

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● the timing of, and the costs involved in, obtaining regulatory approvals for our product candidates;

● the cost of manufacturing our product candidates and any product we successfully commercialize;

● our ability to establish and maintain strategic collaborations, licensing or other arrangements and the financial terms of such agreements;

● the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims, including litigation costs and the outcome

of such litigation; and

● the timing, receipt and amount of sales of, or milestone payments related to or royalties on, our current or future product candidates, if any.

See “Risk Factors” for additional risks associated with our substantial capital requirements.

Internal Controls and Procedures

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-
15(f) under the Exchange Act). Internal control over financial reporting is a process designed by, or under the supervision of, the issuer’s Chief Executive
Officer  and  Chief  Financial  Officer,  or  persons  performing  similar  functions,  and  effected  by  the  issuer’s  board  of  directors,  management  and  other
personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in
accordance with generally accepted accounting principles and includes those policies and procedures that: (i) pertain to the maintenance of records that in
reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the issuer; (ii) provide reasonable assurance that transactions
are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and
expenditures of the issuer are being made only in accordance with authorizations of management and directors of the issuer; and (iii) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the issuer’s assets that could have a material effect on
the financial statements.

Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance
with the policies or procedures may deteriorate.

Under  the  supervision  and  with  the  participation  of  management,  including  our  Chief  Executive  Officer  and  Chief  Financial  Officer,  management  has
assessed  the  effectiveness  of  our  internal  control  over  financial  reporting  based  on  the  criteria  set  forth  in  the  Internal  Control  -  Integrated  Framework
(2013)  issued  by  the  Committee  of  Sponsoring  Organizations,  or  COSO,  of  the  Treadway  Commission,  and  concluded  that  our  internal  control  over
financial reporting was not effective as of December 31, 2019 as a result of material weaknesses in our internal control over financial reporting.

A  material  weakness  is  a  deficiency,  or  a  combination  of  deficiencies,  in  internal  control  over  financial  reporting,  such  that  there  is  a  reasonable
possibility  that  a  material  misstatement  of  the  company's  annual  or  interim  financial  statements  will  not  be  prevented  or  detected  on  a  timely  basis.  In
connection  with  the  assessment  of  the  effectiveness  of  our  internal  control  over  financial  reporting,  our  management  identified  the  following  material
weaknesses that existed as of December 31, 2019:

During 2019, we experienced significant turnover in finance personnel that reduced the complement and skill of the resources within the Company. As a
result, we did not maintain an effective control environment as we lacked a sufficient complement of resources with an appropriate level of knowledge,
experience  and  training  to  design,  maintain  and  monitor  our  internal  control  over  financial  reporting  commensurate  with  our  financial  reporting
requirements. As a result, this material weakness contributed to the following material weaknesses:

● We did not design and maintain controls to ensure adequate segregation of duties within our financial reporting function, including the preparation
and review of journal entries. Specifically, some key accounting personnel had the ability to both prepare and post journal entries without an
independent review by someone without the ability to prepare and post journal entries.

● We did not design and maintain effective controls over certain information technology general controls for information systems that are relevant to

the preparation of our financial statements. Specifically, we did not design and maintain effective user access controls to ensure appropriate
segregation of duties and that adequately restrict user and privileged access to financial applications and data to appropriate Company personnel.

These material weaknesses did not result in a material misstatement of the annual or interim financial statements.  Additionally, these material weaknesses
could  result  in  a  misstatement  of  the  relevant  account  balances  or  disclosures  that  would  result  in  a  material  misstatement  to  the  annual  or  interim
consolidated financial statements that would not be prevented or detected.

This Annual Report on Form 10-K does not include an attestation report of our independent registered public accounting firm due to an exemption from
such requirement for emerging growth companies.

We continue to evaluate the effectiveness of our remediation efforts, including demonstrating that the new or improved controls are designed appropriately
and operate effectively for a reasonable period of time.  We expect to make further changes to our internal controls. The following actions have been, or are
expected to be, taken, to strengthen our controls and organizational structure:

•

•

•

•

To address issues with recent employee turnover, we have hired a new controller, senior accountant, accounting analyst and accounts payable clerk.
We also plan to hire or outsource additional accounting personnel to assist with improving the internal control environment, including a manager of
accounting or senior accountant and director of SEC reporting and internal control. We expect to continue to evaluate our needs for additional
personnel. We plan to leverage the services of consulting firms to assist us with the strengthening and monitoring of our internal controls processes
and documentation. We expect to provide enhanced training to existing and new employees in order to enhance the level of communication and
understanding of controls with key individuals that provide key information and perform key roles within our financial accounting and reporting
group.

We plan to appropriately design, implement and maintain a formal policy that expressly prohibits a manual journal entry from being created and
posted by the same employee. Further, we plan to implement a process that includes the creation of a journal entry report that identifies who
created and posted each journal entry. The report will be reviewed each month by independent senior accounting personnel so that any exceptions
to the policy can be identified on a timely basis and appropriately addressed.

We plan to appropriately design, implement and maintain a formal policy to limit the number of “Super Users”, maintain effective user access
controls to ensure appropriate segregation of duties and adequately restrict user and privileged access to financial applications, programs and data
to appropriate personnel.

We plan to implement a formal policy that preparation, review and approval of account reconciliations will be performed by qualified accounting
personnel independent of those who create and post the related underlying journal entries.   

To assess the effectiveness of internal controls related to the remediation of the 2019 identified material weaknesses, we plan to begin implementing the
remediation described herein. Implementation and testing is expected to occur during the year ending December 31, 2020 and we plan to provide an update
on the status of our remediation activities on a quarterly basis.

JOBS Act

As an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012, as amended, or the JOBS Act, we can take advantage of an
extended  transition  period  for  complying  with  new  or  revised  accounting  standards.  This  allows  an  emerging  growth  company  to  delay  the  adoption  of
certain accounting standards until those standards would otherwise apply to private companies. We have irrevocably elected to “opt out” of this provision
and, as a result, we will comply with new or revised accounting standards when they are required to be adopted by public companies that are not emerging
growth companies.

Subject to certain conditions, as an emerging growth company, we rely on certain of these exemptions, including without limitation:

● reduced disclosure about our executive compensation arrangements;

● no advisory votes on executive compensation or golden parachute arrangements; and

● exemption from the auditor attestation requirement in the assessment of our internal control over financial reporting.

We may take advantage of these exemptions for up to five years or such earlier time that we are no longer an emerging growth company. We would cease to
be  an  emerging  growth  company  on  the  date  that  is  the  earliest  of  (i)  the  last  day  of  the  fiscal  year  in  which  we  have  total  annual  gross  revenues  of
$1.07 billion or more; (ii) the last day of 2023; (iii) the date on which we have issued more than $1.0 billion in nonconvertible debt during the previous
three years; or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the SEC. We may choose to take advantage of some but
not all of these exemptions. Accordingly, the information contained herein may be different from the information you receive from other public companies
in which you hold stock.

Smaller Reporting Company

As  a  “smaller  reporting  company,”  as  defined  in  Rule  12b-2  of  the  Securities  Exchange  Act  of  1934,  as  amended,  or  the  Exchange  Act,  in  addition  to
providing  reduced  disclosure  about  our  executive  compensation  arrangements  and  business  developments,  among  other  reduced  disclosure  requirements
available  to  smaller  reporting  companies,  we  present  only  two  years  of  audited  financial  statements  in  addition  to  any  required  unaudited  interim
financial statements with correspondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure.
Accordingly, the information contained herein may be different from the information you receive from other public companies in which you hold stock.

(a)     Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-
15(f) under the Exchange Act). Internal control over financial reporting is a process designed by, or under the supervision of, the issuer’s Chief Executive
Officer and Chief Financial Officer, or persons performing similar functions, and effected by the issuer’s board of directors, management and other
personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in
accordance with generally accepted accounting principles and includes those policies and procedures that: (i) pertain to the maintenance of records that in
reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the issuer; (ii) provide reasonable assurance that transactions
are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and
expenditures of the issuer are being made only in accordance with authorizations of management and directors of the issuer; and (iii) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the issuer’s assets that could have a material effect on
the financial statements.

Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance
with the policies or procedures may deteriorate.

Under  the  supervision  and  with  the  participation  of  management,  including  our  Chief  Executive  Officer  and  Chief  Financial  Officer,  management  has
assessed  the  effectiveness  of  our  internal  control  over  financial  reporting  based  on  the  criteria  set  forth  in  the  Internal  Control  -  Integrated  Framework
(2013)  issued  by  the  Committee  of  Sponsoring  Organizations,  or  COSO,  of  the  Treadway  Commission,  and  concluded  that  our  internal  control  over
financial reporting was not effective as of December 31, 2019 as a result of material weaknesses in our internal control over financial reporting.

A  material  weakness  is  a  deficiency,  or  a  combination  of  deficiencies,  in  internal  control  over  financial  reporting,  such  that  there  is  a  reasonable
possibility  that  a  material  misstatement  of  the  company's  annual  or  interim  financial  statements  will  not  be  prevented  or  detected  on  a  timely  basis.  In
connection  with  the  assessment  of  the  effectiveness  of  our  internal  control  over  financial  reporting,  our  management  identified  the  following  material
weaknesses that existed as of December 31, 2019:

111

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
During 2019, we experienced significant turnover in finance personnel that reduced the complement and skill of the resources within the Company. As a
result, we did not maintain an effective control environment as we lacked a sufficient complement of resources with an appropriate level of knowledge,
experience  and  training  to  design,  maintain  and  monitor  our  internal  control  over  financial  reporting  commensurate  with  our  financial  reporting
requirements. As a result, this material weakness contributed to the following material weaknesses:

● We did not design and maintain controls to ensure adequate segregation of duties within our financial reporting function, including the preparation
and review of journal entries. Specifically, some key accounting personnel had the ability to both prepare and post journal entries without an
independent review by someone without the ability to prepare and post journal entries.

● We did not design and maintain effective controls over certain information technology general controls for information systems that are relevant to

the preparation of our financial statements. Specifically, we did not design and maintain effective user access controls to ensure appropriate
segregation of duties and that adequately restrict user and privileged access to financial applications and data to appropriate Company personnel.

These material weaknesses did not result in a material misstatement of the annual or interim financial statements.  Additionally, these material weaknesses
could  result  in  a  misstatement  of  the  relevant  account  balances  or  disclosures  that  would  result  in  a  material  misstatement  to  the  annual  or  interim
consolidated financial statements that would not be prevented or detected.

This Annual Report on Form 10-K does not include an attestation report of our independent registered public accounting firm due to an exemption from
such requirement for emerging growth companies.

(b) Evaluation of Disclosure Controls and Procedures

Under the supervision of and with the participation of our management, including our Chief Executive Officer, who is our principal executive officer, and
our Chief Financial Officer, who is our principal financial officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures
as of December 31, 2019, the end of the period covered by this Annual Report on Form 10-K. The term “disclosure controls and procedures,” as defined in
Rules  13a-15(e)  and  15d-15(e)  under  the  Exchange  Act,  means  controls  and  other  procedures  of  an  issuer  that  are  designed  to  ensure  that  information
required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within
the  time  periods  specified  in  the  rules  and  forms  promulgated  by  the  SEC.  Disclosure  controls  and  procedures  include,  without  limitation,  controls  and
procedures  designed  to  ensure  that  information  required  to  be  disclosed  by  an  issuer  in  the  reports  that  it  files  or  submits  under  the  Exchange  Act  is
accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, as appropriate to allow timely
decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide
only  reasonable  assurance  of  achieving  their  objectives,  and  management  necessarily  applies  its  judgment  in  evaluating  the  cost-benefit  relationship  of
possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2019, our Chief Executive Officer
and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were not effective due to the material weaknesses in
internal control over financial reporting discussed above.

112

 
 
 
 
 
 
 
 
 
 
 
 
 
 
(c) Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended December 31, 2019 that have materially affected, or are
reasonably likely to materially affect, our internal control over financial reporting.

Subsequent to our December 31, 2019 year end, we began taking a number of actions, including designing and implementing new controls and revising
existing controls, in order to remediate the material weaknesses described above. We expect to continue our remediation efforts, including testing of
operating effectiveness of new controls, as described below under “Remedial Actions to Address Material Weaknesses” during the year ending December
31, 2020 and we plan to provide an update on the status of our remediation activities on a quarterly basis.

(d) Remedial Actions to Address Material Weaknesses

We continue to evaluate the effectiveness of our remediation efforts, including demonstrating that the new or improved controls are designed appropriately
and operate effectively for a reasonable period of time. We expect to make further changes to our internal controls. The following actions have been, or are
expected to be, taken, to strengthen our controls and organizational structure:

● To address issues with recent employee turnover, we have hired a new controller, senior accountant, accounting analyst and accounts payable clerk.
We also plan to hire or outsource additional accounting personnel to assist with improving the internal control environment, including a manager of
accounting or senior accountant and director of SEC reporting and internal control. We expect to continue to evaluate our needs for additional
personnel. We plan to leverage the services of consulting firms to assist us with strengthening and monitoring of our internal controls processes and
documentation. We expect to provide enhanced training to existing and new employees in order to enhance the level of communication and
understanding of controls with key individuals that provide key information and perform key roles within our financial accounting and reporting
group.

● We plan to appropriately design, implement and maintain a formal policy that expressly prohibits a manual journal entry from being created
and posted by the same employee. Further, we plan to implement a process that includes the creation of a journal entry report that identifies
who created and posted each journal entry. The report will be reviewed each month by independent senior accounting personnel so that any
exceptions to the policy can be identified on a timely basis and appropriately addressed.

● We plan to appropriately design, implement and maintain a formal policy to limit the number of “Super Users”, maintain effective user access
controls to ensure appropriate segregation of duties and adequately restrict user and privileged access to financial applications, programs and
data to appropriate personnel.

● We plan to implement a formal policy that preparation, review and approval of account reconciliations will be performed by qualified

accounting personnel independent of those who create and post the related underlying journal entries.

Testing of Internal Control Effectiveness

To assess the effectiveness of internal controls related to the remediation of the 2019 identified material weaknesses, we plan to begin implementing the
remediation described herein. Implementation and testing is expected to occur during the year ending December 31, 2020 and we plan to provide an update
on the status of our remediation activities on a quarterly basis.

This Annual Report on Form 10-K does not include an attestation report of our independent registered public accounting firm due to an exemption from
such requirement for emerging growth companies.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Liquidia Technologies, Inc.

Opinion on the Financial Statements

We  have  audited  the  accompanying  balance  sheets  of  Liquidia  Technologies,  Inc.  (the  “Company”)  as  of  December  31,  2019  and  2018,  and  the  related
statements of operations and comprehensive loss, of stockholders’ equity (deficit) and of cash flows for the years then ended, including the related notes
(collectively referred to as the “financial statements”). In our opinion, the 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 years then ended in conformity with accounting
principles generally accepted in the United States of America.

Substantial Doubt About the Company’s Ability to Continue as a Going Concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern.  As discussed in Note 2 to the
financial statements, the Company has incurred recurring losses and cash outflows from operations, has an accumulated deficit and has debt maturing within
twelve months that raise substantial doubt about its ability to continue as a going concern.  Management’s plans in regard to these matters are also described
in Note 2. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Changes in Accounting Principles

As discussed in Note 2 to the financial statements, the Company changed the manner in which it accounts for leases in 2019 and the manner in which it
accounts for revenues from contracts with customers in 2018.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s 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 of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform
the  audits  to  obtain  reasonable  assurance  about  whether  the  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 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2014.

Notes to Financial Statements

1. Business

Liquidia Technologies, Inc. (“Liquidia” or the “Company”) is a late-stage clinical biopharmaceutical company focused on the development and
commercialization of novel products utilizing the Company’s proprietary PRINT technology to transform the lives of patients. PRINT is a particle
engineering platform that enables precise production of uniform drug particles designed to improve the safety, efficacy and performance of a wide range of
therapies. The Company is currently focused on the development of two product candidates for which it holds worldwide commercial rights: LIQ861 for the
treatment of pulmonary arterial hypertension (“PAH”) and LIQ865 for the treatment of local post-operative pain.

The development and commercialization activities are conducted at the Company’s headquarters located in Morrisville, North Carolina. The Company was
incorporated under the laws of the state of Delaware in 2004.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The Company has prepared the accompanying financial statements in conformity with generally accepted accounting principles in the United States of
America (“GAAP”). Such financial statements reflect all adjustments that are, in management’s opinion, necessary to present fairly, in all material respects,
the Company’s financial position, results of operations and cash flows and are presented in U.S. Dollars.

Going Concern

The Company’s financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of
assets and the settlement of liabilities and commitments in the normal course of business. The Company's operations have consisted primarily of developing
its technology, developing products, prosecuting its intellectual property and securing financing. The Company has incurred recurring losses and cash
outflows from operations, has an accumulated deficit, and has debt principal payments that commenced in the first quarter of 2020. The Company expects to
continue to incur losses in the foreseeable future and will require additional financial resources to continue to advance its products and intellectual property,
in addition to repaying its maturing debt and other obligations. These conditions raise substantial doubt regarding the Company’s ability to continue as a
going concern.

The Company believes that its existing cash will enable it to fund its operating expenses and capital expenditure requirements, make payments of interest
and principal on its term loan facility with Pacific Western Bank, and remain in compliance with its minimum cash covenant of $8.5 million pursuant to this
term  loan  facility,  through  August  2020.    The  Company  has  based  these  estimates  on  assumptions  that  may  prove  to  be  wrong,  and  it  could  utilize  its
available  capital  resources  sooner  than  it  expects.  The  Company  will  need  to  raise  substantial  additional  capital  to  continue  its  business  operations  and
remain  in  compliance  with  the  minimum  cash  covenant  of  $8.5  million  on  its  debt  during  and  beyond  the  third  quarter  of  2020,  in  addition  to
commercializing  LIQ861,  if  approved.  Such  capital  may  not  be  available  on  a  timely  basis,  on  terms  that  are  favorable  to  the  Company,  or  at  all.
Alternatively,  in  light  of  the  Company's  current  limited  cash  resources,  the  recent  trading  price  of  the  Company's  common  stock,  outstanding  debt  and
associated minimum cash covenant, and based on a review of the status of its programs, resources and capabilities, the Company continues to explore a
wide range of strategic alternatives with the support of its financial advisor, Jefferies LLC, that could maximize stockholder value. The Company's efforts
have been and continue to be focused primarily upon the potential formation of a partnership or a licensing transaction with respect to its lead program,
LIQ861,  for  the  treatment  of  PAH.  Strategic  alternatives  may  also  include  the  sale  of  some  of  the  Company’s  assets  or  proprietary  technologies,  or  a
potential merger or sale of the Company. There can be no assurance that the Company will be able to enter into such a transaction or transactions on a
timely  basis,  on  terms  that  are  favorable  to  the  Company,  or  at  all.  The  financial  statements  do  not  include  any  adjustments  that  might  result  from  the
outcome of this uncertainty.

Reverse Stock Split

On July 12, 2018 and July 19, 2018, the Company’s Board of Directors and stockholders, respectively, approved an amendment to the Company’s amended
and restated certificate of incorporation effecting a 1-for-16.827 reverse stock split of the Company’s issued and outstanding shares of common stock and
convertible preferred stock. The reverse stock split was effective on July 19, 2018. The par value of the common and redeemable convertible preferred stock
was not adjusted as a result of the reverse stock split. All issued and outstanding share and per share amounts included in the accompanying financial
statements have been adjusted to reflect this reverse stock split for all periods presented.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts
of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual amounts could differ from those estimates.

Summary of Significant Accounting Policies

Cash

The Company considers all highly liquid investments with a maturity of three months or less, when purchased, to be cash equivalents. The Company had no
cash equivalents as of December 31, 2019 and 2018.

Accounts Receivable

Accounts receivable are stated at net realizable value including an allowance for doubtful accounts as of each balance sheet date. The Company has not
recorded an allowance for doubtful accounts during the years ended December 31, 2019 and 2018.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and accounts receivable. The Company is exposed
to credit risk, subject to federal deposit insurance, in the event of default by the financial institutions holding its cash to the extent of amounts recorded on
the  balance  sheet.  With  regard  to  cash,  100%  of  the  Company’s  cash  is  held  on  deposit  with  Pacific  Western  Bank.  With  regard  to  revenues  and
concentration  of  credit  risk,  GlaxoSmithKline  plc  (“GSK”  and  “GSK  Inhaled”)  accounted  for  $8.1  and  $0.4  million  of  our  revenue  during  the  years
ended December 31, 2019 and 2018, respectively, or 100% and 15%, respectively, of our total revenue, and $0 or 0% of the Company’s accounts receivable
as of December 31, 2019 and 2018.

Leases

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases, as amended (Topic
842) (“ASU 2016-02”). The provisions of ASU 2016-02 set out the principles for the recognition, measurement, presentation and disclosure of leases for
both lessees and lessors. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the
principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized
based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease
liability for all leases with a term of greater than 12 months regardless of their classification. The Company has elected to account for leases with a term of
12 months or less in a similar manner as under existing guidance for operating leases. ASU 2016-02 supersedes the previous lease standard, Topic 840,
Leases. The guidance is effective for public companies with annual periods and interim periods within those annual periods beginning after December 15,
2018. The Company adopted Topic 842, as amended, as of January 1, 2019, using the modified retrospective approach. The modified retrospective approach
provides a method for recording existing leases at adoption that approximates the results of a full retrospective approach in the year of adoption. In addition,
the Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among others, allowed the
Company to carry forward the historical lease classification. Adoption of the new standard resulted in the recording of net lease assets and lease liabilities of
approximately $6.4 million and $9.1 million respectively, as of January 1, 2019. The standard had no impact on cash flows. For operating leases, the asset
and liability will be expensed over the lease term on a straight-line basis, with all cash flows classified as an operating activity in the Statement of Cash
Flows. For finance leases, interest on the lease liability will be recognized separately from the amortization of the right-of-use asset in the Statement of
Operations and Comprehensive Loss and the repayment of the principal portion of the lease liability will be classified as a financing activity, while the
interest component will be classified as an operating activity in the Statement of Cash Flows.

Property, plant and equipment are stated at cost. Depreciation of property, plant and equipment is computed using the straight-line method over the
estimated useful lives of the assets beginning when the assets are placed in service. Estimated useful lives for the major asset categories are:

Lab and build-to-suit equipment (years)
Office equipment (years)
Furniture and fixtures (years)
Computer equipment (years)

Leasehold improvements

Lesser of life of the asset
or remaining lease term

Major renewals and improvements are capitalized to the extent that they increase the useful economic life or increase the expected economic benefit of the
underlying asset. Maintenance and repairs are charged to operations as incurred. When items of property, plant and equipment are sold or retired, the related
cost and accumulated depreciation or amortization is removed from the accounts, and any gain or loss is included in operating expenses in the
accompanying Statements of Operations and Comprehensive Loss.

Impairment of Long-Lived Assets

The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not
be recoverable. If the estimated future cash flows (undiscounted and without interest charges) from the use of an asset are less than the carrying value, an
impairment is recorded to reduce the related asset to its estimated fair value. To date, no such impairments have occurred.

Deferred Rent

Rent expense is recognized on a straight-line basis over the life of the lease. The difference between rent expense recognized and rental payments, as
stipulated in the lease, is reflected as deferred rent in the accompanying Balance Sheets and amortized over the life of the lease. In addition, deferred rent
also includes landlord incentives on a portion of the leasehold improvement cost, which is amortized over the life of the lease.

Revenue Recognition

The Company adopted ASU 2014-09, Revenue from Contracts with Customers (“Topic 606”) and all the related amendments as of January 1, 2018. The
cumulative effect of the change was an increase of $0.5 million to the balance of accumulated deficit on the Balance Sheet as of January 1, 2018.

The Company derives revenues primarily from licensing its proprietary PRINT technology and from performing research and development services.
Revenues are recognized as services are performed in an amount that reflects the consideration the Company expects to be entitled to in exchange for those
services and technology.

The Company’s research, development and licensing agreements provide for multiple promised goods and services to be satisfied by the Company and
include a license to the Company’s technology in a particular field of study, participation in collaboration committees, performance of certain research and
development services and obligations for certain manufacturing services.

The transaction price for these contracts includes non-refundable fees and fees for research and development services. Non-refundable up-front fees which
may include, for example, an initial payment upon effectiveness of the contractual relationship or payment to secure a right for a future license, are recorded
as deferred revenue and recognized into revenue over time as the Company provides the research services under the contract required to advance the
products to the point where the Company is able to transfer control of the licensed technology to the customer (“Technology Transfer”). The contract
consideration may also include additional non-refundable payments due to the Company based on the achievement of research, development, regulatory or
commercialization milestone events. In agreements involving multiple goods or services promised to be transferred to customers, the Company must assess,
at the inception of the contract, whether each promise represents a separate performance obligation (i.e., is “distinct”), or whether such promises should be
combined as a single performance obligation. As these goods and services are considered to be highly interrelated, they may be considered to represent a
single, combined performance obligation. The Company includes an estimate of the probable amount of milestone payments to which it will be entitled in
the transaction price. The estimate requires evaluation of factors which are outside of the Company’s control and significantly limit the Company’s ability to
achieve the remaining milestone payments. Therefore, the Company has not included any future milestone payments in the transaction price allocated to
research, development and licensing agreements as of December 31, 2018 or December 31, 2019. The Company revises the transaction price to include
milestone payments once the specific milestone achievement is not considered to be subject to a significant reversal of revenue. At that time, the estimated
transaction price is adjusted and a cumulative catch-up adjustment is recorded to adjust the amount of revenue to be recognized from the license inception to
the date the milestone was deemed probable of achievement. The milestone is included with other non-refundable up-front fees and recognized into revenue
over time as the Company continues to provide services under the contract through the Company’s Technology Transfer. The amount of revenue recognized
is based on the proportion of total research services performed to date to the expected services to be provided through the Technology Transfer.

The estimate of the research services to be provided through the Technology Transfer requires significant judgment to evaluate assumptions regarding the
level of effort required for the Company to have performed sufficient obligations for the customer to be able to utilize the licensed technology without
requiring further services from the Company. If the estimated level of effort changes, the remaining deferred revenue is recognized over the revised period
in which the expected research services and Technology Transfer are required. Changes in estimates occur for a variety of reasons, including but not limited
to (i) research and development acceleration or delays, (ii) customer prioritization of research projects, or (iii) results of research and development activities.
The Company recognizes the consideration it is entitled to receive for research and development services, which are primarily billed quarterly in arrears on
a time and materials basis, as the services are performed (under a proportional performance model) and collection is reasonably assured. Additionally, any
up-front or development milestone payments received are also recognized as revenues, over time, under this same proportional performance model.

Royalties related to product sales will be recognized as revenue when the sale occurs since payments relate directly to products that will have been fully
developed and for which the Company will have satisfied all of its performance obligations.

Segment Data

Operating segments are defined as components of an enterprise engaging in business activities from which it may earn revenues and incur expenses, for
which discrete financial information is available and whose operating results are regularly reviewed by the chief operating decision maker in deciding how
to allocate resources and in assessing performance. The Company views its operations and manages its business in one operating segment and all of the
Company operations and long-lived assets are in the United States.

Research and Development Expense

Research and development costs are expensed as incurred and include direct costs incurred to third parties related to the salaries of, and stock-based
compensation for, personnel involved in research and development activities, contractor fees, grant expenses, administrative expenses and allocations of
research-related overhead costs. Administrative expenses and research-related overhead costs included in research and development expense consist of
allocations of facility and equipment lease charges, depreciation and amortization of assets and insurance directly related to research and development
activities.

Patent Maintenance

The Company is responsible for all patent costs, past and future, associated with the preparation, filing, prosecution, issuance, maintenance, enforcement
and defense of United States patent applications. Such costs are recorded as general and administrative expenses as incurred. To the extent that the
Company’s licensees share these costs, such benefit is recorded as a reduction of the related expenses.

Stock-Based Compensation

The Company estimates the grant date fair value of its share-based awards and amortizes this fair value to compensation expense over the requisite service
period or vesting term (see Note 4).

Net Loss Per Share

Basic net loss per share is calculated by dividing net loss attributable to common stockholders by the weighted average shares outstanding during the period,
without consideration of common stock equivalents.

Diluted net loss per share is calculated by adjusting weighted average shares outstanding for the dilutive effect of common stock equivalents outstanding for
the period, determined using the treasury-stock method. For purposes of the diluted net loss per share calculation, stock options and warrants are considered
to be common stock equivalents but are excluded from the calculation of diluted net loss per share because their effect would be anti-dilutive. Due to their
anti-dilutive effect, the calculation of diluted net loss per share for the years ended December 31, 2019 and 2018 does not include the following common
stock equivalent shares:

Warrants

170,925 
1,829,037 

For the years ended December 31, 2019 and 2018 the only reconciling item between basic and diluted net loss per share is the impact of the common stock
warrants that are included in the calculation of basic net loss per share since their exercise price is de minimis, but excluded from the calculation of diluted
net loss per share since the impact of such warrants is antidilutive.

Fair Value of Financial Instruments

The carrying values of cash, accounts receivable, and accounts payable at December 31, 2019 and 2018 approximated their fair value due to the short
maturity of these instruments.

The Company’s valuation of financial instruments is based on a three-tiered approach, which requires that fair value measurements be classified and
disclosed in one of three tiers. The fair value hierarchy defines a three-level valuation hierarchy for disclosure of fair value measurements as follows:

Level 1 — Quoted prices in active markets for identical assets or liabilities;

Level 2 — Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly; and

Level 3 — Unobservable inputs for the asset and liability used to measure fair value, to the extent that observable inputs are not available.

The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value
measurement. The following tables present the placement in the fair value hierarchy of financial liabilities measured at fair value as of December 31, 2019
and 2018:

The fair value of debt is measured in accordance with ASU 2016-01, Financial Instruments–Overall: Recognition and Measurement of Financial Assets and
Financial Liabilities. The fair value is determined based on the exit price notion using credit spreads and an illiquidity premium for each loan. The credit
spread is determined by the credit risk rating, loan rate index, and maturity date. The illiquidity premium is based on the loan’s credit risk rating.

Deferred Offering Costs

The Company capitalizes certain legal, professional accounting and other third-party fees that are directly associated with in-process equity financings as
deferred offering costs until such equity financings are consummated. After consummation of the equity financing, these costs are recorded in stockholders’
equity as a reduction of proceeds generated as a result of the offering. As of December 31, 2019 and 2018, the Company recorded deferred offering costs
relating to its financing activities of $0 and $110,365, respectively, which is included in Prepaid Expenses and Other Assets on the Balance Sheets.

Convertible Instruments

The Company has utilized various types of financing to fund its business needs, including convertible debt and convertible preferred stock, in some cases
with corresponding warrants. The Company considered guidance within FASB ASC 470-20, Debt with Conversion and Other Options, (“ASC 470-20”),
ASC 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”), when accounting for the issuance of
convertible securities. Additionally, the Company reviewed the instruments to determine whether they were freestanding or contain an embedded derivative
and, if so, whether they should be classified in permanent equity, mezzanine equity or as a liability at each reporting period until the amount is settled and
reclassified into equity.

When multiple instruments were issued in a single transaction, the Company allocated total proceeds from the transaction among the individual freestanding
instruments identified. The allocation was made after identifying all the freestanding instruments and the subsequent measurement basis for those
instruments. The subsequent measurement basis determines how the proceeds were allocated. Generally, proceeds were allocated based on one of the
following methods:

•

•

•

Fair value method — The instrument being analyzed is allocated a portion of the proceeds equal to its fair value, with the remaining proceeds
allocated to the other instruments as appropriate.

Relative fair value method — The instrument being analyzed is allocated a portion of the proceeds based on the proportion of its fair value to
the sum of the fair values of all the instruments covered in the allocation.

Residual value method — The instrument being analyzed is allocated the remaining proceeds after an allocation is made to all other
instruments covered in the allocation.

Generally, when there are multiple instruments issued in a single transaction that have different subsequent measurement bases, the proceeds from the
transaction are first allocated to the instrument that is subsequently measured at fair value (i.e., instruments accounted for as derivative liabilities) at its
issuance date fair value, with the residual proceeds allocated to the instrument not subsequently measured at fair value. In the event both instruments in the
transaction are not subsequently measured at fair value (i.e., equity-classified instruments), the proceeds from the transaction are allocated to the
freestanding instruments based on their respective fair values, using the relative fair value method.

After the proceeds are allocated to the freestanding instruments, resulting in an initial discount on the host contract, those instruments were further evaluated
for embedded features (i.e., conversion options) that require bifurcation and separate accounting as a derivative financial instrument pursuant to ASC 815.
Embedded derivatives were initially and subsequently measured at fair value. Under ASC 815, a portion of the proceeds received upon the issuance of the
hybrid contract was allocated to the fair value of the derivative.

The Company accounted for convertible instruments in which it is determined that the embedded conversion options should not be bifurcated from their
host instruments in accordance with ASC 470-20. Under ASC 470-20, the Company recorded, when necessary, discounts to convertible notes or convertible
preferred stock for the intrinsic value of conversion options embedded in the convertible instruments based upon the differences between the fair value of
the underlying common stock at the commitment date of the transaction and the effective conversion price embedded in the convertible instrument, unless
limited by the proceeds allocated to such instrument.

F-13

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Warrant Liabilities

The Company had classified warrants to purchase shares of preferred stock as liabilities on its Balance Sheets as these warrants were freestanding financial
instruments that would require the Company to issue convertible securities upon exercise. The warrants were initially recorded at fair value on date of grant,
and were subsequently remeasured to fair value at each reporting period. Changes in fair value of the warrants were recognized as a component of other
income (expense) in the Statements of Operations and Comprehensive Loss. In conjunction with the Company’s initial public offering (“IPO”) in 2018, the
warrants were converted to warrants for common stock. Following that conversion, these warrants no longer met the criteria to be presented as a liability
and have been reclassified to additional paid-in capital. The Company will no longer include the warrants as liabilities or recognize changes in their fair
value on the Statements of Operations and Comprehensive Loss.

Embedded Derivatives

Embedded derivatives that were required to be bifurcated from the underlying instrument were accounted for and valued as a separate financial instrument.
In conjunction with the Company’s convertible notes, embedded derivatives exist associated with the future consummation of a qualified financing event, as
defined in the notes, and a subsequent discounted conversion of the instrument to capital stock. The embedded derivatives were bifurcated and classified as
derivative liabilities on the Balance Sheets and separately adjusted to their fair values at the end of each reporting period. Changes in fair values of the
derivative liabilities are recognized as a component of other income (expense) in the Statements of Operations and Comprehensive Loss. These embedded
derivatives were eliminated upon conversion of the underlying convertible notes into Series D preferred stock, $0.001 par value per share (“Series D”) (see
Note 3).

Issuance Costs Related to Equity and Debt

The Company allocated issuance costs between the individual freestanding instruments identified on the same basis as proceeds were allocated. Issuance
costs associated with the issuance of stock or equity contracts (i.e., equity-classified warrants and convertible preferred stock) were recorded as a charge
against the gross proceeds of the offering. Any issuance costs associated with the issuance of liability-classified warrants were expensed as incurred.
Issuance costs associated with the issuance of debt (i.e., convertible debt) was recorded as a direct reduction of the carrying amount of the debt liability, but
limited to the notional value of the debt. The Company accounted for debt as liabilities measured at amortized cost and amortizes the resulting debt discount
to interest expense using the straight-line method over the expected term of the notes pursuant to ASC 835, Interest (“ASC 835”). To the extent that the
reduction from issuance costs of the carrying amount of the debt liability would reduce the carrying amount below zero, such excess was recorded as
interest expense.

Income Taxes

The asset and liability method is used in the Company’s accounting for income taxes. Under this method, deferred tax assets and liabilities are determined
based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are
expected to be in effect when the differences are expected to reverse. The Company records a valuation allowance against deferred tax assets when
realization of the tax benefit is uncertain.

A valuation allowance is recorded, if necessary, to reduce net deferred taxes to their realizable values if management believes it is more likely than not that
the net deferred tax assets will not be realized.

The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on
examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a
position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement.

On December 22, 2017, the Tax Cuts and Jobs Act (the "TCJA") was enacted into law. This law includes significant changes to the U.S. corporate income
tax system, including a permanent reduction in the corporate income tax rate from 35% to 21%, limitations on the deductibility of interest expense and
executive compensation and the transition of U.S. international taxation from a worldwide system to a territorial tax system. For taxpayers with revenues
over a certain threshold, the TCJA also limits interest expense deductions to 30% of taxable income before interest, depreciation and amortization from
2018 to 2021 and then taxable income before interest thereafter. The TCJA permits disallowed interest expense to be carried forward indefinitely. The
Company calculated its best estimate of the impact of the TCJA in its income tax provision for the year ended December 31, 2017 in accordance with its
understanding of the TCJA and guidance available at the time. The overall impact of the TCJA resulted in a decrease to the deferred tax assets and a
corresponding decrease to the valuation allowance of $14.1 million. Using the guidance issued by the SEC staff in Staff Accounting Bulletin No. 118, the
Company completed its accounting for the TCJA during the fourth quarter of 2018.

Recent Accounting Pronouncements

In October 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606
("ASU 2018-17"). The provisions of ASU 2018-18 clarify when certain transactions between collaborative arrangement participants should be accounted
for under ASC 606 and incorporates unit-of-account guidance consistent with ASC 606 to aid in this determination. The guidance is effective for annual
periods and interim periods within those annual periods beginning after December 15, 2019, with early adoption permitted, and is effective for the Company
for the year ending December 31, 2020. The Company is currently evaluating the impact that the implementation of this standard will have on the
Company's financial statements.

3. Stockholders’ Equity

Authorized Capital

As of December 31, 2019, the authorized capital of the Company consists of 50,000,000 shares of capital stock, $0.001 par value per share, of which
40,000,000 shares are designated as common stock and 10,000,000 shares are designated as preferred stock.

Preferred Stock

In February 2018, the Company received proceeds of $25.6 million in exchange for the corresponding sale of Series D and related rights offering to new and
existing investors. The applicable issue price per share for the Series D was $0.59808, subject to adjustment as provided in the certificate of incorporation.
In addition, all outstanding convertible notes, plus accrued interest, totaling $28.9 million were converted into Series D at the same price per share without a
discount. Outstanding warrants to purchase shares of Series C-1 preferred stock, $0.001 par value per share (“Series C-1”), were converted to warrants to
purchase the equivalent number of shares of Series D. All references herein to these warrants refer to them as warrants to purchase Series D. In total,
91,147,482 shares of Series D were issued. Each share of Series D was convertible at any time into a share of common stock with such conversion ratio
subject to future adjustment. Conversion was automatic upon a qualified financing, as defined in the certificate of incorporation. Each series of preferred
stock had anti-dilution protection in the event of a dilutive issuance, as defined in the certificate of incorporation. The Series D was senior to all other series
of preferred stock.

Common Stock

Upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, the holders of the common stock shall be entitled to
receive that portion of the remaining funds to be distributed to the stockholders, subject to the liquidation preferences of any outstanding preferred stock, if
any. Such funds shall be paid to the holders of common stock on the basis of the number of shares so held by each of them.

In the third quarter of 2018, the Company closed the IPO of 4,833,099 shares of common stock, including the underwriters’ partial exercise of their over-
allotment option in connection therewith, which resulted in aggregate net proceeds of $47.3 million, after underwriting discounts and the payment of other
offering expenses. In conjunction with the Company’s IPO, all outstanding shares of convertible preferred stock were converted into an aggregate of
9,948,207 shares of common stock and the Class B non-voting common stock, $0.001 par value per share, was converted into shares of voting common
stock.

F-15

 
 
 
 
 
 
 
 
 
 
 
 
 
In March 2019, the Company closed an underwritten follow-on offering of 3,000,000 shares of its common stock at a public offering price of $11.50 per
share. The gross proceeds from the offering were $34.5 million and net proceeds were $31.8 million, after deducting underwriting discounts and
commissions and other offering expenses.

In August 2019, the Company entered into a sales agreement (the “ATM Agreement”) with Jefferies LLC (“Jefferies”) to issue and sell shares of the
Company’s common stock, having an aggregate offering price of up to $40.0 million, from time to time during the term of the ATM Agreement, through an
“at-the-market” equity offering program at the Company’s sole discretion, under which Jefferies will act as the Company’s agent and/or principal. The
Company will pay Jefferies a commission up to 3.0% of the gross proceeds of any common stock sold through Jefferies under the ATM Agreement. During
the year ended December 31, 2019, the Company sold 2,409,356 shares of common stock for gross proceeds of $8.4 million and net proceeds were $8.1
million, after deducting underwriting discounts and other offering expenses under the ATM Agreement.

On December 23, 2019, the Company entered into a Common Stock Purchase Agreement (the “Purchase Agreement”) with certain institutional accredited
investors (the “Purchasers”) for the sale by the Company in a private placement (the “Private Placement”) of an aggregate of 7,164,534 shares (the “Private
Placement Shares”) of common stock, at a purchase price of $3.13 per Private Placement Share. The closing of the Private Placement occurred on
December 27, 2019. The Company granted the Purchasers indemnification rights with respect to its representations, warranties, covenants and agreements
under the Purchase Agreement. The gross proceeds from the sale of the Private Placement Shares were $22.4 million and net proceeds were $21.0 million,
after deducting placement agent fees and offering expenses.

Warrants

Pursuant to the terms of the warrants, upon the conversion of the preferred stock underlying the warrants into common stock, the warrants automatically
become exercisable for common stock based upon the conversion ratio of the underlying preferred stock.

Upon closing of the Series D financing, the Company had warrants outstanding to purchase 3,698,128 shares of Series D. In conjunction with the IPO in the
third quarter of 2018, these warrants were automatically converted into warrants to purchase 219,761 shares of common stock. During the years ended
December 31, 2019 and 2018, 64,629 and 48,836 warrants to purchase shares of common stock were exercised, respectively. As of December 31, 2019,
there are outstanding warrants to purchase 106,274 shares of common stock with an exercise price of $0.0168 per share. The warrants expire on December
31, 2026.

4. Stock-Based Compensation

The Company’s 2018 Long-Term Incentive Plan (the “2018 Plan”) was approved by stockholders in July 2018. In addition to stock options, the 2018 Plan
provides for the granting of stock appreciation rights, stock awards, stock units, and other stock-based awards. A total of 1,600,000 shares of the Company’s
common stock was initially authorized and reserved for issuance under the 2018 Plan. This reserve will automatically increase each subsequent anniversary
of January 1 through 2028, by an amount equal to the smaller of (a) 4% of the number of shares of common stock issued and outstanding on the
immediately preceding December 31, or (b) an amount determined by the Board of Directors (the “Evergreen Provision”).

On January 1, 2019, the number of shares of common stock available for issuance under the 2018 Plan automatically increased by 620,778 shares from
1,600,000 shares to 2,220,778 shares pursuant to the Evergreen Provision. On January 1, 2020, the number of shares of common stock available for issuance
under the 2018 Plan automatically increased by 1,129,250 shares from 1,287,561 shares to 2,416,811 shares pursuant to the Evergreen Provision. The 2018
Plan provides for accelerated vesting under certain change of control transactions. As of December 31, 2019, there were 1,287,561 shares of common stock
available for issuance under 2018 Plan.

F-16

 
 
 
 
 
 
 
 
 
 
 
 
The  2018  Plan  replaced  the  2016  and  2004  Plans  as  the  Company’s  primary  long-term  incentive  program.  The  2016  and  2004  Plans  were  discontinued
following stockholder approval of the 2018 Plan, but the outstanding awards under the 2016 and 2004 Plans will continue to remain in effect in accordance
with their terms. Shares that are returned under the 2016 and 2004 Plans upon cancellation, termination or otherwise of awards outstanding under the 2016
and 2004 Plans will not be available for grant under the 2018 Plan. As of December 31, 2019, the Company had reserved for issuance 733,820 shares of
common stock under the 2016 Plan and 397,177 shares of common stock under the 2004 Plan representing the remaining outstanding options granted under
the 2016 and 2004 Plans.

Stock-Based Compensation Valuation and Expense

The  Company  accounts  for  its  employee  stock-based  compensation  plans  using  the  fair  value  method.  The  fair  value  method  requires  the  Company  to
estimate the grant-date fair value of its stock-based awards and amortize this fair value to compensation expense over the requisite service period or vesting
term. The fair value of each option grant is estimated using a Black-Scholes option-pricing model.

For restricted stock units (“RSUs”), the grant-date fair value is based upon the market price of the Company’s common stock on the date of the grant. This
fair value is then amortized to compensation expense over the requisite service period or vesting term.

Stock-based compensation expense is recognized net of estimated forfeitures such that expense is recognized only for those stock-based awards that are
expected to vest. A forfeiture rate is estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures materially differ from
initial estimates.

The Company recorded the following stock-based compensation expense:

The following describes each of these assumptions and the Company’s methodology for determining each assumption:

Expected Dividend Yield
The dividend yield percentage is zero because the Company neither currently pays dividends nor intends to do so during the expected option term.

Risk-Free Interest Rate
The risk-free interest rate is based on the U.S. Treasury yield curve approximating the term of the expected life of the award in effect on the date of grant.

Expected Volatility
Expected  stock  price  volatility  is  based  on  an  average  of  several  peer  public  companies.  For  purposes  of  identifying  peer  companies,  the  Company
considered characteristics such as industry, length of trading history and similar vesting terms.

Expected Life
The  expected  life  represents  the  period  the  awards  are  expected  to  be  outstanding.  The  Company’s  historical  share  option  exercise  experience  does  not
provide a reasonable basis upon which to estimate an expected term because of a lack of sufficient data. Therefore, the Company estimates the expected
term by using the simplified method.

5. License Agreements

The Company performs research under a license agreement with The University of North Carolina at Chapel Hill (“UNC”) as amended to date (the “UNC
Letter Agreement”). As part of the UNC Letter Agreement, the Company holds an exclusive license to certain research and development technologies and
processes in various stages of patent pursuit, for use in its research and development and commercial activities, with a term until the expiration date of the
last to expire patent subject to the UNC Letter Agreement, subject to industry standard contractual compliance. Under the UNC Letter Agreement, the
Company is obligated to pay UNC royalties equal to a low single digit percentage of all net sales of drug products whose manufacture, use or sale includes
any use of the technology or patent rights covered by the UNC Letter Agreement. The Company may grant sublicenses of UNC licensed intellectual
property in return for specified payments based on a percentage of any fee, royalty or other consideration received.

In September 2015, GSK Inhaled exercised the option to permanently license the technology for a non-refundable payment to the Company of $15.0
million. Pursuant to the license provisions of the collaboration agreement, GSK Inhaled is potentially required to pay the Company for certain milestones
reached in addition to tiered royalties on the worldwide sales of the licensed products at percentages ranging from the mid-single digits to low-single digits
depending on the total number of products developed and other royalty step-down events with a fixed low-single digit royalty floor. In February 2016, GSK
Inhaled paid the Company a $3.0 million milestone payment pursuant to the collaboration agreement. The combined $18 million in up-front and milestone
payments was subject to deferral pursuant to the adoption of ASC 606 and the revenue policy described herein.

In July 2018, GSK notified the Company of its plans to discontinue development of the inhaled antiviral for viral exacerbations in chronic obstructive
pulmonary disease under the GSK Inhaled collaboration agreement after completion of the related Phase 1 clinical trial. In June 2019, the Company and
GSK executed the third amendment to the collaboration agreement providing the Company rights to develop and commercialize additional inhaled
programs at the Company’s sole cost. This amendment granted the Company the right to develop three additional molecular entities for application in
inhaled programs using the Company’s PRINT technology and a mechanism to acquire further molecular entities for inhaled applications. New inhaled
programs developed under this amendment would carry milestone and royalty payments due to GSK upon initiation of Phase 3 studies and subsequent
commercialization, respectively. This amendment, among other factors including the lack of continued performance anticipated by the Company and GSK
under the original agreement, led the Company to the belief that no further research and development services will be provided to GSK under the
collaboration agreement and the earnings process related to the up front and development milestone payments previously received under the collaboration
agreement was completed under the proportional performance model. Therefore, the remaining deferred revenue of $8.1 million was recognized as revenue
during the year ended December 31, 2019. If GSK were to request additional services under the original agreement, which the Company believes is a
remote likelihood, the Company does not expect the value of any incremental efforts that the Company might agree to perform to be material. Any potential
milestone or royalty payments from the Company to GSK associated with this amendment will be recorded as operating expenses. Accordingly, in January
2020, the Company notified GSK of its intent to terminate the GSK Inhaled collaboration agreement based upon GSK's lack of performance under the
agreement, which the Company believes constitutes a material breach of the agreement. In February 2020, the Company received a letter from GSK
disputing the Company’s basis for termination. The parties are currently attempting to resolve the dispute pursuant to the terms of the agreement.

In June 2016, the Company entered into a development and license agreement with G&W Laboratories (“G&W”) to develop multiple products for topical
delivery in dermatology using the Company’s PRINT technology (the “G&W Agreement”). The first non-refundable up-front fee of $1.0 million was
received in June 2016. Research and development services commenced in July 2016 on the first program pursuant to this agreement. In April 2018, the
Company and G&W mutually agreed to terminate the G&W Agreement. As a result, during the second quarter of 2018, the remaining unamortized balances
in the related deferred revenue and deferred sublicense payments of $0.9 million and $0.1 million, respectively, were fully recorded as Revenues and Cost of
Sales, respectively, in the Statement of Operations and Comprehensive Loss for the year ended December 31, 2018.

Deferred Sublicense Payments

Sublicense payments to UNC are considered direct and incremental fulfillment costs of the Company’s research, development and licensing agreements as
the PRINT technology resources used by the Company are continually researched by UNC. These costs are deferred and then amortized into Cost of Sales
over the same estimated period of benefit as the period of the underlying revenue recognition. In conjunction with the June 2019 amendment to the GSK
collaboration agreement, the balance of deferred sublicense payments of $807,192 were expensed to Cost of Sales in the same period. As of
December 31, 2019, the balances of these unamortized payments was $0. As of December 31, 2018, the balances of these unamortized payments included in
current and long-term prepaid expenses and other assets was $0 and $807,192, respectively.

The Company recorded depreciation and amortization expense of $2,567,742 and $1,543,667 for the years ended December 31, 2019 and 2018,
respectively. Maintenance and repairs are expensed as incurred and were $220,658 and $153,278, respectively, for the years ended December 31, 2019 and
2018.

In December 2016, the Company executed an agreement with a commercial manufacturer to build a PRINT particle fabrication line for the production of
LIQ861. The ultimate cost was approximately $1.6 million. The Company financed this transaction with a third-party vendor, CSC Leasing Company
(“CSC”). CSC made payments to the manufacturer per the payment schedule in the agreement as the asset was fabricated. CSC charged the Company
a monthly lease rate on the scheduled payments made to the manufacturer as interim financing costs until the asset was completed and placed in service.
Upon completion of fabrication, the lease commenced in March 2018 (“CSC Financing”).

In accordance with ASC 840, Leases, for build-to-suit arrangements where the Company is involved in the fabrication of an asset prior to the
commencement of the ultimate financing or takes some level of construction risk, the Company is considered the accounting owner of the assets during the
fabrication period. Accordingly, during the fabrication phase, the Company recorded a construction-in-progress asset within Property, Plant and Equipment
and a corresponding deferred financing obligation liability for contributions by CSC toward fabrication. Upon completion of the fabrication in March 2018,
since the Company maintained substantially all of the risk and rewards of ownership of the asset, the Company recorded the transaction as a financing,
continuing to record the asset and reclassifying the deferred financing obligation to debt. In accordance with Topic 842, Leases, the CSC Financing was
recharacterized as a finance lease in the first quarter of 2019 and accounted for accordingly (see Note 9).

The following table details the activity of Construction in Progress (“CIP”) in 2019 and 2018 and the associated transfer to Leasehold Improvements and

8. Income Taxes

No provision for federal and state income tax expense has been recorded for the years ended December 31, 2019 and 2018 due to the valuation allowance
recorded against the net deferred tax asset and recurring losses.

As of December 31, 2019 and 2018, the Company established a full valuation allowance against its net deferred tax assets since, at the time, the Company
could not assert that it was more likely than not that its deferred tax assets would be realized. As a result, there was an increase in the valuation allowance in
2019 of $11,178,295.

As of December 31, 2019, the Company had federal and state income tax loss carryforwards of $97,268,927 and $184,191,027, respectively, which begin to
expire in 2024 for federal purposes and in 2019 for state purposes. As of December 31, 2019, the Company had federal and state income tax loss
carryforwards of $85,765,810 and $778,925, respectively, which carryforward indefinitely. In addition, the Company has tax credit carryforwards for federal
tax purposes of $3,175,600 as of December 31, 2019, which begin to expire in 2026. The utilization of net operating loss and tax credit carryforwards to
reduce future income taxes will depend on the Company’s ability to generate sufficient taxable income prior to the expiration of the loss carryforwards.

The Internal Revenue Code of 1986, as amended, contains provisions which limit the ability to utilize the net operating loss carryforwards in the case of
certain events, including significant changes in ownership interests. If the Company’s net operating loss carryforwards are limited, and the Company has
taxable income which exceeds the permissible yearly net operating loss carryforwards, the Company would incur a federal income tax liability even though
net operating loss carryforwards would be available in future years.

The Company has determined that there may be a future limitation on the Company’s ability to utilize its entire federal R&D credit carryover. Therefore, the
Company recognized an uncertain tax benefit associated with the federal R&D credit carryover during the years ended December 31, 2019 and 2018, as
follows:

Balance at December 31, 2017
Increases related to 2018
Increases related to prior periods

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on
examination by the taxing authorities based on the technical merits of the position. The Company has determined that it had no other material uncertain tax
benefits for the year ended December 31, 2019.The Company’s policy for recording interest and penalties related to uncertain tax provisions is to record
them as a component of the provision for income taxes. The Company did not have any accrued interest or penalties associated with any unrecognized tax
positions as of December 31, 2019 and 2018, and there were no such interest or penalties recognized during the years ended December 31, 2019 and 2018.

The Company has all tax years open to examination by federal tax and state tax jurisdictions. No income tax returns are currently under examination by
taxing authorities.

9. Leases, Commitments and Contingencies

Leases

The Company leases certain lab space, office space, and equipment. Leases with an initial term of 12 months or less are not recorded on the Balance Sheet;
the Company recognizes lease expense for these leases on a straight-line basis over the lease term. For lease agreements entered into or reassessed after the
adoption of Topic 842, the Company combines lease and non-lease components, if any. Most leases include one or more options to renew. The exercise of
lease renewal options is at the Company’s sole discretion. Certain leases also include options to purchase the leased property. Consistent with past practice
and current intent, the Company has recognized all such purchase options as part of its right-of-use assets and lease liabilities. The depreciable life of assets
and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. The
Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.

The Company conducts its operations from leased facilities in Morrisville, North Carolina. As of December 31, 2019, the Company’s amended leases for its
primary building is for usage of approximately 45,000 square feet of space expiring October 31, 2026. The leases are for general office, laboratory, research
and development and light manufacturing space. The lease agreements require the Company to pay property taxes, insurance, common area expenses and
maintenance costs. In November 2018, the Company amended the lease of its primary building to expand by 8,264 additional square footage expiring
October 31, 2026 in exchange for terminating the Company’s other lease with the same landlord for 4,400 noncontiguous square feet. A tenant allowance of
approximately $1.0 million was also made available for use to help fund the build out related to the expansion of the primary building lease. The
incremental rent over the terminated lease for the first 12 months of this lease expansion amounts to $0.1 million, subject to lease escalation in subsequent
periods. In June 2019, the Company signed a commitment to incur construction costs of up to $3.1 million related to the leasehold improvements for this
lease expansion, against which the tenant allowance will be applied. The leasehold improvements were substantially completed in 2019 and the Company
took occupancy of the additional square footage in 2019. The total construction costs incurred in 2019 approximated $2.8 million and the remaining
estimated costs to be incurred as of December 31, 2019 is not expected to be material.

The Company leases specialized lab equipment under finance leases. The related right-of-use assets are amortized on a straight-line basis over the lesser of
the lease term or the estimated useful life of the asset.

The CSC Financing (see Note 7) has a term of three years with equal monthly payments. The CSC Financing is secured by a lien on the related build-to-suit
equipment and includes an option to purchase the build-to-suit equipment at maturity at an amount equal to the lesser of fair market value or 23% of the
initial financed amount. The right-of-use assets related to finance leases net of amortization is $1,981,002 as of December 31, 2019 and is included in lab
equipment, build-to-suit equipment, computer equipment and leasehold improvements within property, plant and equipment in the accompanying balance
sheet (see Note 7). The Company does not have access to certain inputs used by its lessors to calculate the rate implicit in its finance leases. As such, the
Company utilizes its estimated incremental borrowing rate for the discount rate applied to its finance leases. The incremental borrowing rate used on finance
leases was 7.5%.

In January 2016 and October 2016, the Company entered into a Loan and Security Agreement (“LSA”) and an amendment, respectively, with Pacific
Western Bank (“Pacific Western”). The LSA provided that the Company may borrow up to $10.0 million in three tranches of a term loan (“Term Loan”) to
supplement working capital and finance facility expansion and capital equipment purchases. The Term Loan was collateralized by a lien on all assets of the
Company that are not otherwise encumbered, including a negative pledge on intellectual property prohibiting its sale without Pacific Western’s consent.
Amounts borrowed under the Term Loan could be repaid at any time without penalty or premium. The Term Loan was interest-only through July 6, 2017,
followed by an amortization period of 30 months of equal monthly payments of principal plus interest, beginning on August 6, 2017 and continuing on the
same day of each month thereafter until paid in full. Any amounts borrowed under the Term Loan bore interest at 3.75% during the initial 18-month interest-
only period. Following the interest-only period, the interest rate increased to 5.00%, which was to be fixed for the duration of the Term Loan. Subsequent to
the Company closing its IPO, on August 6, 2018 the Company paid Pacific Western a liquidity event success fee of $400,000, which was recorded as
Interest Expense in the Statement of Operations and Comprehensive Loss for the year ended December 31, 2018.

In March 2018, the Company and Pacific Western executed the Ninth Amendment to the LSA (the “Ninth Amendment”). With the Ninth Amendment, new
covenants were enacted requiring the Company to (1) at all times maintain a balance of cash at Pacific Western of at least $8.0 million, an increase of $5.5
million from its prior cash balance covenant, and (2) not observe any materially adverse data from its LIQ861 Phase 3 study on or before December 31,
2018. Pursuant to this Ninth Amendment, the interest-only period for the Tranche I loan was amended to include the period from January 7, 2018 to July 6,
2018, and the interest-only period for the Tranche II and Tranche III loans was amended to include the period from January 13, 2018 to July 12, 2018. Prior
to executing the amendment, the Company had made principal payments of $0.6 million inside of the defined interest-only period, which were subsequently
refunded on the same day. All amendments to the Pacific Western LSA were accounted for as a modification.

In October 2018, the Company and Pacific Western entered into an Amended and Restated Loan and Security Agreement (the “A&R LSA”) in which the
Company received an initial tranche of $11.0 million to extinguish its existing debt of $8.0 million under the LSA, repay in full the $1.8 million in
outstanding indebtedness under the UNC Promissory Note and for general corporate purposes. The indebtedness under the A&R LSA bears interest at the
greater of the Prime rate or 5% and has a four-year term maturing in October 2022. The A&R LSA provided for access to a second tranche of up to $5.0
million available to be drawn at the Company’s option through June 30, 2019. The second tranche became accessible as a result of the full enrollment of the
Company’s LIQ861 INSPIRE clinical trial, without observing any materially adverse data through the two week endpoint. The entire second tranche of $5.0
million was drawn by the Company in May 2019 bringing the total amount outstanding to $16.0 million. Both tranches require payments of interest-only
through December 31, 2019. As a result of this refinancing, the Company recorded a gain of $0.1 million in accordance with ASC 470-50, Debt –
Modifications and Extinguishments.

The A&R LSA carries a one-time success fee of $375,000 and a prepayment penalty of 1% if the drawn tranche is prepaid prior to October 27, 2020. The
success fee was triggered in December 2019 by the sale of common stock and this was recorded as interest expense of $375,000 during the year ended
December 2019. Accrued interest is included in Other accrued expenses in the Balance Sheet as of December 31, 2019. The minimum cash covenant is $8.5
million. Pacific Western maintains a blanket lien on all assets excluding intellectual property, for which it has been provided a negative pledge. Pursuant to
the A&R LSA, the Company is also obligated to comply with various other customary covenants, including, among others, restrictions on its ability to
dispose of assets, replace or suffer the departure of the CEO or CFO without delivering ten days’ prior written notification to Pacific Western, suffer a
change on the Board of Directors which would result in the failure of at least one partner of Canaan Partners or their respective affiliates to serve as a voting
member in each case without having used best efforts to deliver at least 15 days’ prior written notification to Pacific Western, make acquisitions, be
acquired, incur indebtedness, grant liens, make distributions to its stockholders, make investments, enter into certain transactions with affiliates or pay down
subordinated debt, subject to specified exceptions.

In May 2019, the Company and Pacific Western entered a First Amendment to A&R LSA to provide for a limit of $2.5 million of capital expenditures
during the year ended December 31, 2019. As of December 31, 2019, the Company was in compliance with this and all other covenants.

Scheduled annual maturities of long-term debt as of December 31, 2019 are as follows:

11. Warrant Liability Change in Fair Value During Year 2018

The Company’s liability-classified warrants to purchase preferred stock were recorded as a liability at their estimated fair value at the date of issuance, with
the subsequent changes in estimated fair value recorded in warrant fair value adjustments in the Company’s Statements of Operations and Comprehensive
Loss. The warrants, with a fair value of $4,474,122 at inception, were initially recorded as a warrant liability on the Balance Sheet with a corresponding
discount to the notes. The change in the estimated fair value of the warrant liability resulted in a fair value adjustment and is included in warrant fair value
adjustments in the Statements of Operations and Comprehensive Loss. In conjunction with the IPO during the year ended December 31, 2018, the warrants
automatically converted to warrants to purchase common stock. Therefore, upon the IPO, the warrant liability was marked to fair market value and
transferred to additional paid-in capital. Changes in the values of the warrant liability for the years ended December 31, 2019 and 2018 are summarized
below:

Exhibit 4.4

DESCRIPTION OF THE REGISTRANT’S SECURITIES REGISTERED PURSUANT TO SECTION 12 OF THE SECURITIES EXCHANGE
ACT OF 1934

As of December 31, 2019, the only class of securities of Liquidia Technologies, Inc., a Delaware corporation (the “Company”), registered under Section 12
of the Securities Exchange Act of 1934, as amended, is common stock, par value $0.001 per share (“common stock”). The following description of the
Company’s common stock and preferred stock, $0.001 par value per share (“preferred stock”), summarizes the material terms and provisions of the
Company’s common stock and preferred stock.

General

The total number of shares of capital stock that the Company has authorized is 50,000,000, divided into two classes consisting of (i) 40,000,000 shares of
common stock and (ii) 10,000,000 shares of preferred stock.

As of March 1, 2020, there were 28,365,093 shares of common stock issued and outstanding and an additional 2,129,702 shares issuable upon exercise of
outstanding options and warrants. Of the 2,129,702 shares of common stock issuable upon exercise of outstanding options and warrants, 1,649,357 shares
are issuable to the Company’s officers, directors and principal stockholders and 480,345 shares are issuable to other employees. Furthermore, as of March 1,
2020, 6,555 shares of common stock are issuable upon the vesting of restricted stock units issued to Neal Fowler, the Company’s Chief Executive Officer.

As of March 1, 2020, there were no shares of preferred stock issued and outstanding.

Common Stock

The holders of common stock are entitled to one vote per share on all matters to be voted upon by the stockholders. At a meeting of stockholders at which a
quorum is present, for all matters other than the election of directors, an affirmative vote of the majority of shares entitled to vote on a matter and that are
represented either in person or by proxy at a meeting of stockholders decides all questions, unless the matter is one upon which a different vote is required
by express provision of law or the Company’s amended and restated certificate of incorporation or amended and restated bylaws, each as may be amended
from time to time. The holders of common stock are entitled to receive ratably those dividends, if any, that may be declared from time to time by the
Company’s board of directors (the “Board”) out of funds legally available, subject to preferences that may be applicable to preferred stock, if any, then
outstanding. In the event of a liquidation, dissolution or winding up of the Company, the holders of common stock will be entitled to share ratably in all
assets remaining after payment of liabilities, subject to prior distribution rights of preferred stock, if any, then outstanding. The common stock has no
preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the common stock. All
outstanding shares of common stock are fully paid and non-assessable.

Preferred Stock

The Board is authorized to issue preferred stock in one or more series, to establish the number of shares to be included in each such series and to fix the
designation, powers, preferences and rights of these shares and any qualifications, limitations or restrictions thereof. The issuance of preferred stock may
have the effect of delaying, deferring or preventing a change in control of the Company without further action by the stockholders and may adversely affect
the voting and other rights of the holders of common stock. The issuance of preferred stock with voting and conversion rights may adversely affect the
voting power of the holders of common stock, including the loss of voting control to others. At present, the Company has no plans to issue any of the
preferred stock.

Warrants

As of March 1, 2020, the Company had outstanding warrants to purchase an aggregate of 106,274 shares of common stock at an exercise price of $0.0168
per share. These warrants expire on December 31, 2026.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Registration Rights

On December 23, 2019, the Company entered into a common stock purchase agreement for a private placement with certain purchasers whereby, on
December 27, 2019 the Company issued and sold 7,164,534 shares of common stock at a price of $3.13 per share for aggregate gross proceeds of
approximately $22.4 million (the “Private Placement”).  In connection with the Private Placement, on December 23, 2019, the Company entered into a
registration rights agreement with the purchasers (the “Registration Rights Agreement”), pursuant to which the Company agreed to file a registration
statement with the U.S. Securities and Exchange Commission (the “SEC”) covering the resale of the shares of common stock sold in the Private Placement.
The Company agreed to file such registration statement within 60 days following the date of the Registration Rights Agreement, which registration
statement was filed with the SEC on February 3, 2020 and declared effective by the SEC on February 13, 2020. The Registration Rights Agreement includes
customary indemnification rights in connection with the registration statement.

Additionally, the Company entered into a Seventh Amended and Restated Investors' Rights Agreement (“IRA”) on February 2, 2018 with its then-largest
stockholders. Subject to the terms of the IRA, Holders (as defined in the IRA) of shares having registration rights (“Registrable Securities”, as defined in the
IRA) can demand that the Company file a registration statement or request that their shares be covered by a registration statement that the Company is
otherwise filing, until the earliest to occur of: (i) five years following the consummation of the Company’s initial public offering, or July 30, 2023, (ii) as to
any Holder, such earlier time after the Company’s initial public offering at which such Holder can sell all Registrable Securities held by such Holder
(together with any affiliate of the Holder with whom such Holder must aggregate its sales under Rule 144) in a single three (3)-month period without
registration in compliance with Rule 144 of the Securities Act of 1933, as amended (the “Securities Act”), or (iii) after the consummation of a "Liquidation
Event," as defined in the IRA.

Demand Registration Rights.    At any time after six months following the closing of the Company’s initial public offering, or January 30, 2019, subject to
certain exceptions set forth in the IRA, if the Holders of at least a majority of the common stock issued upon conversion of the Series C, Series C-1 and
Series D preferred stock demand that the Company file a registration statement covering the registration of Registrable Securities with an anticipated
aggregate offering price of at least $10 million, the Company is required to use all commercially reasonable efforts to effect, as soon as practicable, the
registration under the Securities Act of all Registrable Securities requested to be registered.

Form S-3 Registration Rights.    If the Company receives from the Holders of Registrable Securities a written request that the Company effects a registration
on Form S-3, the Company is required to provide written notice of the proposed registration to all other Holders and use all commercially reasonable efforts
to effect the registration of such shares on Form S-3; provided, however, that such Form S-3 registration right is subject to a number of exceptions, such as
the Company being eligible to use Form S-3 at the time such Form S-3 registration request is made, the proposed sale of Registrable Securities to be
registered on Form S-3 having an aggregate price to the public (net of any underwriters' discounts or commissions) of at least $5 million and the Company
not being required to file more than two registration statements on Form S-3 in a 12-month period. Furthermore, the Company has the ability to delay the
filing of a registration statement under specified conditions, such as for a period of time following the effective date of a prior registration statement, if the
Board deems it detrimental to the Company and the Company’s stockholders to delay the filing. Such postponements cannot exceed 90 days during any 12-
month period and cannot be made more than once in any 12-month period.

Piggyback Registration Rights.    If the Company proposes to register any of its securities under the Securities Act in connection with the public offering of
such securities, the Company is required to, at such time, promptly give each Holder party to the IRA written notice of such registration. Upon the written
request of each such Holder given within 20 days after receipt of the Company’s registration notice, the Company is required to use all commercially
reasonable efforts to cause to be registered under the Securities Act all of the Registrable Securities that each holder requests to be registered. In connection
with any such offering, the Company is not required to include any of the Holders' securities in such underwriting unless they accept the terms of the
underwriting as agreed between the Company and the underwriters selected by the Company and enter into an underwriting agreement in customary form
with such underwriters, and then only in such quantity as the underwriters determine in their sole discretion will not jeopardize the success of the offering
by the Company. If marketing factors require a limitation of the number of shares to be underwritten, then the number of shares that may be included in the
underwriting will be allocated, first, to the Company; second, to the Holders other than the Common Holders on a pro rata basis based on the total number
of Registrable Securities held by such Holders; third, to the Common Holders on a pro rata basis based on the total number of Registrable Securities held by
the Common Holders; and fourth, to any stockholder other than a Holder and/or Common Holder on a pro rata basis.

 
 
 
 
 
 
 
 
 
Expenses of Registration.  The Company will pay all expenses, other than underwriting discounts and commissions, related to any demand, Form S-3 or
piggyback registration, including without limitation all registration, filing and qualification fees, printers' and accounting fees, fees and disbursements of
counsel for the Company and the reasonable fees and disbursements of one counsel for the selling Holders, not to exceed $50,000.

Indemnification.    The IRA contains customary cross-indemnification provisions under which the Company is obligated to indemnify the selling
stockholders in the event of material misstatements or omissions or other "Violation," as defined in the IRA, in the registration statement attributable to the
Company, and they are obligated to indemnify the Company for material misstatements or omissions or other Violation attributable to them.

Termination of Registration Rights.    All registration rights granted under the IRA will terminate on the fifth anniversary of the completion of the
Company’s initial public offering, or July 30, 2023.

Anti-Takeover Effects of the Company’s Charter and Bylaws and Delaware Law

Some provisions of Delaware law and the Company’s amended and restated certificate of incorporation and amended and restated bylaws could make the
following transactions more difficult:

● acquisition of the Company by means of a tender offer, a proxy contest or otherwise; and

● removal of the Company’s incumbent officers and directors.

These provisions, summarized below, are expected to discourage and prevent coercive takeover practices and inadequate takeover bids. These provisions are
designed to encourage persons seeking to acquire control of the Company to negotiate first with the Board. They are also intended to provide Company
management with the flexibility to enhance the likelihood of continuity and stability if the Board determines that a takeover is not in the best interests of its
stockholders. These provisions, however, could have the effect of discouraging attempts to acquire the Company, which could deprive the Company’s
stockholders of opportunities to sell their shares of common stock at prices higher than prevailing market prices. The Company believes that the benefits of
these provisions, including increased protection of the Company’s potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal
to acquire or restructure the Company, outweigh the disadvantages of discouraging takeover proposals, because negotiation of takeover proposals could
result in an improvement of their terms.

Election and Removal of Directors

The Company’s amended and restated certificate of incorporation and amended and restated bylaws contain provisions that establish specific procedures for
appointing and removing members of the Board. Under the Company’s amended and restated certificate of incorporation and amended and restated bylaws,
the Board consists of three classes of directors: Class I, Class II and Class III. A nominee for director shall be elected to the Board if the votes cast for such
nominee’s election exceed the votes cast against such nominee’s election. Each director will serve a three-year term and will stand for election upon the
third anniversary of the annual meeting at which such director was elected. In addition, the Company’s amended and restated certificate of incorporation and
amended and restated bylaws provide that vacancies and newly created directorships on the Board may be filled only by a majority of the directors then
serving on the Board. Under the Company’s amended and restated certificate of incorporation, directors may be removed by the stockholders only by the
affirmative vote of the holders of at least a majority of the voting power of all of the then-outstanding shares of the Company’s capital stock entitled to vote
generally in the election of directors, voting together as a single class.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Authorized but Unissued Shares.    The authorized but unissued shares of common stock and preferred stock are available for future issuance without any
further vote or action by the Company’s stockholders. These additional shares may be utilized for a variety of corporate purposes, including future public
offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of authorized but unissued shares of common stock
and preferred stock could render more difficult or discourage an attempt to obtain control over the Company by means of a proxy contest, changes in the
Company’s management, tender offer, merger or otherwise. In particular, the authorization of undesignated preferred stock makes it possible for the Board
to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of the Company.

Stockholder Action; Advance Notification of Stockholder Nominations and Proposals.    The Company’s amended and restated certificate of incorporation
and amended and restated bylaws require that any action required or permitted to be taken by its stockholders must be effected at a duly called annual or
special meeting of stockholders and does not allow for stockholders to act by written consent without a meeting. In addition, the Company’s amended and
restated bylaws provide that candidates for director may be nominated and other business brought before an annual meeting only by the Board or by a
stockholder who gives written notice to the Company no later than 90 days prior to nor earlier than 120 days prior to the first anniversary of the last annual
meeting of stockholders. These provisions may have the effect of deterring unsolicited offers to acquire the Company or delaying changes in the Company’s
management, which could depress the market price of the common stock.

Special Stockholder Meetings.    Under the Company’s amended and restated certificate of incorporation and amended and restated bylaws, only the Board,
the Chairman of the Board or the Company’s Chief Executive Officer may call special meetings of stockholders.

Delaware Anti-Takeover Law.    The Company is subject to Section 203 of the Delaware General Corporation Law (the “DGCL”), which is an anti-takeover
law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder for a
period of three years following the date that the person became an interested stockholder, unless the business combination or the transaction in which the
person became an interested stockholder is approved in a prescribed manner. Generally, a business combination includes a merger, asset or stock sale, or
another transaction resulting in a financial benefit to the interested stockholder. Generally, an interested stockholder is a person who, together with affiliates
and associates, owns 15% or more of the corporation’s voting stock. The existence of this provision may have an anti-takeover effect with respect to
transactions that are not approved in advance by the Board, including discouraging attempts that might result in a premium over the market price for the
shares of common stock held by stockholders.

No Cumulative Voting.    Under Delaware law, cumulative voting for the election of directors is not permitted unless a corporation’s certificate of
incorporation authorizes cumulative voting. The Company’s amended and restated certificate of incorporation does not provide for cumulative voting in the
election of directors. Cumulative voting allows a minority stockholder to vote a portion or all of its shares for one or more candidates for seats on the Board.
Without cumulative voting, a minority stockholder will not be able to gain as many seats on the Board based on the number of shares of Company stock the
stockholder holds as the stockholder would be able to gain if cumulative voting were permitted. The absence of cumulative voting makes it more difficult
for a minority stockholder to gain a seat on the Board to influence its decision regarding a takeover.

Amendment of Charter Provisions.    The amendment of certain of the above provisions in the Company’s amended and restated certificate of incorporation
and amended and restated bylaws requires approval by holders of at least a majority of the Company’s outstanding capital stock entitled to vote generally in
the election of directors.

These and other provisions could have the effect of discouraging others from attempting hostile takeovers, and, as a consequence, they may also inhibit
temporary fluctuations in the market price of the common stock that often result from actual or rumored hostile takeover attempts. These provisions may
also have the effect of preventing changes in the Company’s management. It is possible that these provisions could make it more difficult to accomplish
transactions that stockholders might otherwise deem to be in their best interests.

 
 
 
 
 
 
 
 
 
 
Exclusive Forum

The Company’s amended and restated certificate of incorporation provides 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 (1) derivative action or proceeding brought on behalf of the Company, (2) action asserting a claim
of breach of a fiduciary duty owed by any director or officer of the Company to the Company or its stockholders, (3) action asserting a claim against the
Company arising pursuant to any provision of the DGCL or the Company’s amended and restated certificate of incorporation or amended and restated
bylaws or (4) action asserting a claim against the Company governed by the internal affairs doctrine. Any person or entity purchasing or otherwise acquiring
any interest in shares of capital stock of the Company shall be deemed to have notice of and consented to the forum provisions in the Company’s amended
and restated certificate of incorporation. However, the enforceability of similar forum provisions in other companies’ certificates of incorporation has been
challenged in legal proceedings, and it is possible that a court could find these types of provisions to be unenforceable.

Transfer Agent

The transfer agent and registrar for the Company’s common stock is Computershare Trust Company, N.A. and its address is 250 Royall Street, Canton, MA
02021.

(m)          Tenant’s Other Lease.  Landlord and Tenant specifically acknowledge and agree that, as of the date of this Lease, (i) Tenant is in

occupancy of approximately 4,401 rentable square feet of flex space contained in Suite 500 of another building in the Project, known as Keystone
Technology Park - Building VII and located at 627 Davis Drive, Durham, North Carolina 27713, pursuant to a separate lease agreement with an execution
date of April 14, 2005, by and between another landlord in the Project, GRE Keystone Technology Park Two LLC, successor by acquisition of Technology
V1I-IX, LLC and Tenant (as such may be amended, “Tenant’s Other Lease”), and (ii) Tenant’s Other Lease has an expiration date of August 31, 2010.

3.01          Term.

ARTICLE 3 - TERM AND POSSESSION

(a)          This Lease shall be and continue in full force and effect for the term set forth in Subsection 2.01(g), as it may be modified,

renewed and extended pursuant to Exhibit G or by written agreement between Landlord and Tenant (the “Term”).  Subject to the remaining provisions of
this Article, the “Commencement Date” shall be the date on which Landlord tenders possession of the Leased Premises to Tenant, which such date is
anticipated to be the Target Commencement Date shown in Subsection 2.01(h).  The Term shall commence on the Commencement Date and shall expire,
without notice to Tenant, on the last day of the last month of the Term (the “Expiration Date”) (i.e. if the Commencement Date is other than the first (1) day
of the month, the Expiration Date shall nevertheless be the last day of the last month of the Term).

(b)          If the Commencement Date and Expiration Date are different from the Target Commencement Date and the Target Expiration

Date, respectively, as set forth in Subsection 2.01(h), Landlord shall prepare and, Landlord and Tenant shall execute an amendment to the Lease setting forth
such actual dates, and adjusting any Base Rent payment schedule, if applicable.  If such amendment is not executed, the Commencement Date and
Expiration Date shall be conclusively deemed to be the Target Commencement Date and the Target Expiration Date set forth in Subsection 2.01(h).

(c)          Upon the expiration or other termination of this Lease, Landlord shall have the right to immediately re-enter and take possession

of the Leased Premises.

3.02          Commencement.

(a)          Subject to Section 3.03 hereof, if, (i) any of the work described in Exhibit C that is required to be performed by Landlord or

Landlord’s contractors) to prepare the Leased Premises for occupancy has not been substantially completed on or before the Target Commencement Date or
(ii) Landlord is unable to tender possession of the Leased Premises to Tenant on the Target Commencement Date, then the Commencement Date (and
commencement of installments of Base Rent) shall be postponed until Landlord is able to tender possession of the Leased Premises to Tenant with the work
to be performed in the Leased Premises having been substantially completed and the postponement shall operate to extend the Expiration Date in order to
give full effect to the stated duration of the Term.

(b)          The Leased Premises shall be deemed to be substantially complete the day after inspection and approval for occupancy for the

intended use, whether permanent, conditional, or temporary, by the City of Durham, North Carolina, provided said approval is subsequently evidenced by a
certificate of occupancy, whether permanent, conditional, or temporary, issued by said municipality, which such certificate of occupancy may be dated when
actually processed by such municipality, rather than the date of the inspection and approval for occupancy.

3

 
 
 
 
 
 
 
 
 
 
 
and Tenant shall have no, and waives any, claim against Landlord because of any such delay.

(c)          The deferment of installments of Base Rent shall be Tenant’s exclusive remedy for postponement of the Commencement Date,

3.03          Tenant’s Delay.

No delay in the completion of the Leased Premises resulting from delay or failure on the part of Tenant in furnishing information or other matters

required in Exhibit C, and no delay resulting from any cause set forth in Section 6 of Exhibit C, shall delay the Commencement Date, Expiration Date or
commencement of payment of Rent (as defined in Section 4.02 below).  In addition to the foregoing, in the event any laboratory related material(s),
equipment, or fixtures contained in the Upfit (defined in Exhibit C) requires more than eight (8) weeks to deliver to the Leased Premises for construction as
part of the Upfit, then the time that is greater than eight (8) weeks for Landlord’s receipt of such item shall also constitute a Tenant delay (e.g., if it takes
nine (9) weeks for Landlord to receive an item contained in the Upfit then one (1) week of such time shall be a Tenant delay).

3.04          Tenant’s Possession.

Except as specifically set forth in Exhibit C, Section 7, if, prior to the Commencement Date, Tenant shall enter into possession of all or any part of
the Leased Premises and conducts any portion of its business operations therein, the Term, the payment of monthly installments of Base Rent and all other
obligations of Tenant to be performed during the Term shall commence on, and the Commencement Date shall be deemed to be, the date of such entry;
provided, no such early entry shall operate to change the Expiration Date.

3.05          Acceptance of Leased Premises.

Tenant shall confirm its acceptance of the Leased Premises by execution of the Acceptance of Leased Premises Memorandum attached hereto
as Exhibit B.  Tenant shall execute and deliver such Acceptance of Leased Premises Memorandum to Landlord within ten (10) business days of receipt
thereof, and Tenant’s failure to do same shall be considered an event of default under this Lease.

3.06          Holdover.

If Tenant shall remain in possession of the Leased Premises after the expiration or earlier termination of this Lease without the execution of a new
lease or an amendment to this Lease extending the Term, Tenant shall become a tenant-at- sufferance, and for a period of sixty (60) calendar days after such
termination or expiration, as the case may be, shall pay daily rent at one hundred fifty percent (150%) of the per day Rent (as defined in Section 4.02)
payable with respect to the last full calendar month immediately prior to the end of the Term or termination of this Lease, but otherwise shall be subject to
all of the terms, conditions, provisions and obligations of this Lease, and such tenancy may be terminated at any time on seven (7) calendar days’ prior
written notice.  After such sixty (60) day period Tenant shall continue to be a tenant-at-sufferance, terminable on one (1) day’s notice, and shall pay daily
rent at double the per day Rent payable with respect to the last full calendar month immediately prior to the end of the Term or termination of this Lease, but
otherwise shall be subject to all of the obligations of Tenant under this Lease.  Tenant shall indemnify Landlord (i) against all claims for damages by any
other tenant to whom Landlord may have leased all or any part of the Leased Premises effective upon the termination or expiration of this Lease, and (ii) for
all other losses, costs and expenses, including consequential damages and reasonable attorneys’ fees, sustained or incurred by reason of such holding over. 
In the event of any holdover and failure of Tenant to pay the holdover rent set forth herein, Landlord shall have the right to immediately apply the Security
(as defined and set forth in Section 4.07) to the Rent, at the holdover rate set forth herein, for as many days as would be represented by the amount of the
Security.  Nothing contained herein shall be construed as a consent by Landlord to any holding over by Tenant.  The rights and obligations contained in this
Section shall survive the expiration or other termination of this Lease.

3.07          Condition of Leased Premises.

(a)          As of the Commencement Date of the Lease, to the best of Landlord’s knowledge, the Leased Premises and the Total Improved

Leasable Area of Building (including the roof) (i) shall comply with all applicable laws, statutes, orders, ordinances, rules and regulations, including,
without limitation, all applicable mechanical, electrical and plumbing codes (the “Laws”), (ii) shall be suitable for the purpose for which they are let, and
(iii) shall be in good repair and condition.

4

 
 
 
 
 
 
 
 
 
 
 
 
 
(b)          (i) Notwithstanding the foregoing, Tenant expressly understands and agrees that Tenant shall be obligated to fully pay for any

work and materials required to bring the Leased Premises into compliance with all applicable laws, statutes, orders, ordinances, rules, regulations and
mechanical, electrical and plumbing codes when such required work arises out of any one (1) or more of the following: (A) Tenant’s use of the Leased
Premises, or a portion of the Leased Premises, for anything other than general office purposes (i.e., “other than general office purposes” shall include, but
not be limited to, laboratory, research and development, and light manufacturing purposes); (B) the fact that the square footage of the Leased Premises is
less than that of the Total Improved Leasable Area of Building as such is stated in Section 2.01(c); (C) Tenant’s desired configuration of the Leased
Premises or a portion of the Leased Premises; (D) any changes in applicable laws, statutes, orders, ordinances, rules, regulations and/or mechanical,
electrical and plumbing codes which become effective after the Commencement Date.  Landlord expressly understands and agrees that any work and the
need for materials arising out of that which is described in subsections (b)(i)(A) through (b)(i)(D) above may be paid for out of the Allowance and/or the
Additional Allowance (as described and set forth in Exhibit C and Section 4.09).

(ii)          Subject to subsections (b)(i) (A) through (C) above.  Landlord shall be fully responsible for any costs associated with

any work or materials required to be completed in order to make the Leased Premises and the Total Improved Leasable Area of Building compliant with the
Laws as of the Commencement Date, and, notwithstanding Section 9.06 of this Lease (Default by Landlord), in the event a violation of the Laws is
discovered during construction of the Upfit, and such violation does not arise out of any of the circumstances stated in subsection (b)(i) (A) through
(C) above, Landlord shall, in good-faith and using commercially reasonable efforts, diligently proceed to remedy any such violation.

(c)          Landlord further agrees to use its best efforts to cause the Upfit (defined in Exhibit C) to be constructed in a good and

workmanlike manner.  Upon the completion of the Upfit, Landlord and Tenant shall perform a “walk-through” of the Leased Premises and shall compile a
“punch-list” of remaining Upfit items to be completed by Landlord within thirty (30) days of the walk-through of the Leased Premises.

calendar month during the Term.  If the Commencement Date is not the first day of a month, Tenant shall be required to pay on the Commencement Date a

As used in this Lease, “Rent” shall mean the Base Rent, Additional Rent (defined below), late charges, and all other amounts required to be paid by

Tenant pursuant to this Lease.  The Rent shall be paid at the times and in the amounts provided herein by check drawn on a United States of America bank

4.04          TICAM Expense Adjustment

(a)          If the TICAM Expenses (defined below) for the Building for any calendar year, expressed on a per square foot basis, exceed the

TICAM Expenses for the initial calendar year of the Term specified in Subsection 2.01(e), Tenant shall pay to Landlord increased Rent (a “TICAM Expense
Adjustment”) in an amount equal to the product of such excess times the square feet of the Leased Premises as stated in Subsection 2.01(b).  The TICAM
Expense Adjustment shall be payable in monthly installments on the first day of each calendar month based on Landlord’s estimate of the TICAM Expenses
for the then current year.

(b)          Landlord may at any time give Tenant written notice specifying Landlord’s estimate of the TICAM Expenses for the then current

calendar year or the subsequent calendar year and specifying the TICAM Expense Adjustment to be paid by Tenant for each such year, and Tenant shall
adjust its payments accordingly beginning with the monthly installment immediately following Landlord’s notice.

(c)          Within one hundred twenty (120) calendar days after the end of each calendar year, Landlord shall give written notice to Tenant

specifying the actual TICAM Expenses for the prior calendar year and any necessary adjustment to the TICAM Expense Adjustment paid by Tenant for that
calendar year (the “Notice”).  Tenant shall pay any deficit amount to Landlord within thirty (30) calendar days after receipt of Landlord’s written notice. 
Any excess payment by Tenant for the prior calendar year shall reduce the TICAM Expense Adjustment for the following calendar year.  If there is any
excess payment applicable to the last year of the Term, Landlord shall refund such excess to Tenant within thirty (30) calendar days of sending the Notice
applicable to the final year of the term.  This obligation shall survive termination of this Lease Notwithstanding the foregoing, for purposes of determining
Tenant’s annual TICAM Expense Adjustment in any calendar year of the Term, the TICAM Expenses which are controllable by Landlord (the “Controllable
Expenses”) shall not exceed the Controllable Expenses for the first (1st) calendar year of the Term increased at a rate of five percent (5%), compounded
annually.  There shall be no such limitation with respect to taxes, insurance, utilities, refuse collection, snow removal, and any other TICAM Expense item
not within Landlord’s reasonable control (the “Uncontrollable Expenses”).  All other TICAM Expenses, other than the Uncontrollable Expenses, shall be
Controllable Expenses.

(d)          Tenant shall have the right, one (1) time per year, upon written notice to Landlord, within sixty (60) calendar days of receipt of
the Notice, to have Landlord’s books and records relating solely to TICAM Expenses contained in the statement for the prior year, reviewed.  If Landlord’s
calculation of TICAM Expenses fails to comply with the requirements of this Section 4.4 or contains any other error, as determined by the review, Tenant’s
past payments of its proportionate share of TICAM Expenses for the subject year shall be adjusted in accordance with the results of the review, and
appropriate payments shall be made by Landlord or Tenant, as the case may be, within forty-five (45) calendar days after completion of the review.

(e)          All books and records necessary to accomplish any review permitted under this Section 4.04 shall be retained by Landlord for a

period of one (1) year, and shall be made available to the person conducting the review at the Building, Project or the office of Landlord’s property manager,
during normal business hours.  All of Landlord’s and Tenant’s costs of the review shall be paid by Tenant unless the review reveals that total TICAM
Expenses controllable by Landlord were misstated by five percent (5%) or more in the calendar year reviewed, in which case Landlord shall reimburse
Tenant for Tenant’s reasonable cost of the review, not to exceed One Thousand Five Hundred Dollars ($1,500.00).  The rights and obligations contained in
this Section 4.04 shall survive the expiration or other termination of this Lease.

(f)          The term “TICAM Expenses” shall mean, except as otherwise specified in this definition, all expenses, costs, and disbursements

of every kind and nature, computed on an accrual basis, which Landlord shall pay or become obligated to pay because of or in connection with the
ownership and operation of the Building, or Landlord’s efforts to reduce TICAM Expenses, including, without limitation:

contained in the foregoing sentence are not intended to, and shall not, limit any right that Tenant might otherwise have to obtain injunctive relief against
Landlord or Landlord’s successors in interest or any suit or action in connection with enforcement or collection of amounts which may become owing or
payable under or on account of liability insurance maintained by Landlord.

the “Existing Condition”.  All demolition of and improvements made to the Existing Condition of the Leased Premises in accordance with the Schematic
Space Plan and Detailed Plans (both defined below) shall be deemed the “Upfit”.

2.          Allowances.

(a)          Landlord shall provide Tenant with a tenant improvement allowance in an amount not to exceed the sum of (i) Four Hundred Twenty-four

Thousand Two Hundred Dollars (S424.200.00) and (ii) Two Hundred Ninety-one Thousand Six Hundred Thirty-seven Dollars and Fifty
Cents ($291,637.50) for a total amount of Seven Hundred Fifteen Thousand Eight Hundred Thirty-seven Dollars and Fifty Cents
($715,837.50) (the “Allowance”), to pay for all costs and expenses incurred by Landlord for the design and construction of the Upfit,
including (A) any demolition related thereto, (B) any architectural work, and (C) any plumbing, mechanical and electrical work, as set
forth below.

(b)          In addition to the foregoing Allowance, in the event the cost of the Upfit exceeds the amount of the Allowance, and Tenant provides

written notice to Landlord that Tenant so elects, then Landlord shall pay for an amount in excess of the Allowance, up to a maximum of
Seven Hundred Sixty-eight Thousand Eight Hundred Sixty-two Dollars and Fifty Cents ($768,862.50) (the Amortized Allowance, defined
in Section 4.091, as such shall be amortized and repaid to Landlord, pursuant to Section 4.09.  Any amount in excess of the total of the
Allowance and the Amortized Allowance shall be due and payable to Landlord in accordance with Section 4 herein.

3.          Design.  Landlord shall cause an architect and one or more engineers, each of whom shall be designated by Landlord in its sole discretion,
to consult with Tenant and to prepare architectural, plumbing, mechanical and electrical plans that are (i) consistent with the “Schematic Space Plan” for the
Leased Premises, which shall be completed on or before ten (10) calendar days after the Execution Date, and when executed by both parties, shall
automatically become attached to this Lease as Exhibit C-l, (ii) sufficiently detailed for pricing, approval and construction of the Upfit, and (iii) subject to
Landlord’s approval, in its reasonable discretion (the “Detailed Plans”).  All partitions, doors, hardware, ceiling tile, window coverings, plumbing, HVAC,
lighting fixtures, switches, outlets and life safety items shall be designed in Landlord’s standard manner.  Carpet, paint, wall covering, and millwork shall be
selected and designed in Landlord’s standard manner and from Landlord’s standard finishes, unless otherwise requested by Tenant, in accordance
with Section 4 herein.  Tenant shall famish to Landlord all other information and technical data reasonably necessary for the preparation of the Detailed
Plans within five (5) business days of Landlord’s request therefor, or as otherwise agreed to by Tenant and Landlord, so as not to delay the design, pricing,
approval and construction of the Upfit by the Target Commencement Date.

4.          Approval of Plans and Cost.  Landlord shall cause a general contractor or contractors designated by Landlord, at its sole discretion, to

prepare detailed pricing of construction of the Upfit pursuant to the Detailed Plans.  Landlord shall submit to Tenant for Tenant’s approval (i) the Detailed
Plans and (ii) an itemized cost statement of all design and construction costs related to the Upfit (the “Cost Statement”).  Such Cost Statement shall include,
but not be limited to, all costs associated with any contractor’s general conditions, permits (including any new or changes to development, facility or
transportation impact fees), taxes, insurance and fees.  Landlord shall not charge Tenant any commercially unreasonable overtime rates to ensure the
completion of the office portion of the Upfit by the Target Commencement Date.  Within five (5) business days after its receipt of the Detailed Plans and
Cost Statement, Tenant shall approve the Detailed Plans and the Cost Statement in writing, subject to any modifications or changes in the Detailed Plans
requested by Tenant.  Landlord, in its sole discretion, shall retain final approval rights for the Detailed Plans.  After Tenant’s approval of the Detailed Plans
and the Cost Statement or in the event Tenant does not respond to Landlord within such five (5) business day period, the Detailed Plans and the Cost
Statement shall be deemed to be approved by Tenant, and such approved Detailed Plans shall be thereafter deemed the “Plans”.  Notwithstanding anything
to the contrary contained herein, if the architectural and engineering design, demolition (if applicable), and construction costs of the Upfit as approved by
Tenant, exceed the Allowance and the Amortized Allowance, then Tenant shall be obligated to pay for all such excess costs.  Landlord shall submit an
invoice to Tenant for such excess costs at the time the Detailed Plans and Cost Statement are approved or deemed approved by Tenant, and Tenant shall pay
such excess costs within fifteen (15) calendar days of receipt of Landlord’s invoice therefor.  Any subsequent changes or modifications to the Plans shall be
made and accepted in writing by Landlord and Tenant and shall constitute an amendment to the Lease, and Tenant shall pay for any additional sums caused
by such changes or modifications to the Plans immediately upon receipt of Landlord’s invoice therefor.  If the cost of designing and constructing the Upfit
as approved by Tenant is less than the Allowance, Tenant shall not be entitled to any refund of the unused portion of the Allowance, but Tenant shall be
allowed to apply any such unused portion of the Allowance to the Additional Upfit, as set forth in Section 4.09.

 
 
 
 
 
 
 
 
 
 
 
5.          Construction.  After Tenant (i) approves the Detailed Plans and the Cost Statement, (or if Tenant does not respond to Landlord regarding

the Detailed Plans and the Cost Statement, as set forth in Section 4 herein), and (ii) pays any and all costs in excess of the Allowance as set forth in
Section 4 herein, then Landlord shall be entitled to cause, and shall cause, the general contractor designated by Landlord to construct the Upfit in
accordance with the Plans and the Cost Statement.

6.          Delay.  The Commencement Date, Expiration Date, and commencement of installments of Monthly Base Rent shall not be postponed or

delayed as a result of any of the following:

(1)          Tenant’s failure to furnish information or consult with Landlord or Landlord’s architects or engineers when requested in order to prepare

the Detailed Plans (including, failure to complete the Schematic Space Plan within ten (10) business days of the Execution Date of this Lease);

(2)          Any laboratory related material(s), equipment, or fixtures contained in the Upfit requiring more than eight (8) weeks to deliver to the

(4)          Changes to the Plans requested or caused by Tenant after Tenant’s approval of the Detailed Plans and Cost Statement; or,

(5)          Any other delay from any other cause attributable to Tenant, its agents, consultants, contractors, subcontractors or employees.

7.          Tenant’s Access to Leased Premises.  Landlord shall permit Tenant and its agents reasonable access to the Leased Premises during normal
business hours thirty (30) calendar days prior to the Target Commencement Date for the purpose of installing telephone and computer cabling, equipment,
fixtures and other personal property, and such entry and use of the Leased Premises shall not constitute acceptance of the Leased Premises nor Tenant’s
acknowledgment of the Commencement Date of the Lease, unless Tenant commences the operation of any portion of its business therein.  This right of
entry onto the Leased Premises is a license from Landlord to Tenant which is subject to revocation in the event that Tenant or its employees, contractors or
agents causes or is the cause of any code or governmental violation, labor dispute, delay or damage during such period which results from, whether directly
or indirectly, the installation or delivery of the foregoing, or otherwise becomes in default of any term, covenant or condition of this Lease as provided in    . 
Prior to Tenant’s entry onto the Leased Premises in accordance herewith.  Tenant shall demonstrate to Landlord that it has obtained the insurance required
and is in compliance with Section 8.04 of the Lease.  Under no circumstances shall Landlord be liable or responsible for and Tenant agrees to assume all
risk of loss or damage to such telephone and computer cabling, equipment, fixtures and other personal property and to indemnify, defend and hold Landlord
harmless from any liability, loss or damage arising from any damage to the property of Landlord, or its contractors, employees or agents, and any death or
personal injury to any person or persons to the extent caused by, attributable to or arising out of, whether directly or indirectly, Tenant’s entry onto the
Leased Premises or the delivery, placement, installation, or presence of the telephone and computer cabling, equipment, fixtures and other personal property,
except to the extent that such loss or damage is caused solely by Landlord’s willful misconduct or gross negligence or the willful misconduct or gross
negligence of Landlord’s contractors, agents or employees.

 
 
 
 
 
 
 
 
 
 
 
8.          Warranties.  Landlord shall cause the repair or replacement of any defects in material or workmanship in the Upfit installed by Landlord for
a period of one (1) year after the date of substantial completion of the Leased Premises, or the duration of any manufacturer’s warranty, whichever is longer,
provided Tenant notifies Landlord of such defect as soon as reasonably practicable after the date Tenant discovers such defect.  LANDLORD MAKES NO
WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE, IN CONNECTION WITH THE UPFIT EXCEPT AS EXPRESSLY SET FORTH IN THIS SECTION 8.  Tenant’s sole
remedy for the breach of any applicable warranty shall be the remedy set forth in this Section 8.  Tenant agrees that no other remedy, including without
limitation, incidental or consequential damages for lost profits, injury to person or property or any other incidental or consequential loss, shall be available
to Tenant.

9.          Compliance with Certain Requirements.  At any time before, during, and after construction, Landlord shall have the right to require

changes to the Plans and construction in order to comply with applicable building codes, other governmental requirements, and insurance requirements. 
Neither Landlord’s nor Tenant’s approval of the Plans is a warranty that the Plans comply with applicable building codes, other governmental requirements,
and insurance requirements.

10.        No Liability.  Notwithstanding the review and approval by Landlord of the Detailed Plans and any changes to same, Landlord shall have

no responsibility or liability, including the costs of additional or corrective work, in regard to the safety, sufficiency, adequacy or legality thereof, and Tenant
shall look solely to the party(ies) preparing same as the party(ies) responsible for ensuring that such Detailed Plans and changes thereto (and the
architectural and engineering completeness and sufficiency thereof and the Upfit constructed as a result thereof) are in compliance with all applicable laws
and regulations, and Tenant’s stated intended use.

that Tenant may use the Allowance), be permitted to install a security system at the Leased Premises, including, without limitation, an access card and lock
system, provided Tenant requests and obtains Landlord’s written approval (which approval shall not be unreasonably withheld) of the specific security
system prior to the commencement of installation.

Building or of defects therein or in any fixtures or equipment, or of any known emergency in the Building.

(16)          Tenant shall place a water-proof tray under all plants in the Leased Premises and shall be responsible for any damage to the floors,

carpets, and/or any other damage caused by over-watering such plants.

(17)          Tenant shall not use the Leased Premises or allow the Leased Premises to be used for photographic, multibit, multigraph or digital

reproductions, except in connection with its own business and not as a service for others, without Landlord’s prior written permission.

(18)          Tenant shall not use or permit any portion of the Leased Premises to be used for any uses other than those specifically granted in

Tenant’s Lease.

(19)          Tenant shall not advertise for laborers (i.e.  those who perform physical labor outdoors) giving the Leased Premises as an address, nor

pay such laborers at a location in the Leased Premises.

 
 
 
 
 
 
 
 
 
 
 
 
 
(20)          Employees of Landlord or Landlord’s agent(s) shall not perform any work or do anything outside of their regular duties, unless under

special instructions from Landlord or Landlord’s agent(s).

(21)          Without the prior approval of Landlord, in Landlord’s sole discretion, Tenant shall not place a load upon any floor of the Leased
Premises which exceeds the load per square foot which such floor was designed to carry and which is allowed by law, regulation or code.  Business
machines and mechanical and electrical equipment belonging to Tenant which cause noise, vibration, electrical or magnetic interference, or any other
nuisance that may be transmitted to the structure or other portions of the Building or to the Leased Premises to such a degree as to be reasonably
objectionable to Landlord or which interfere with the use or enjoyment by other tenants of their leased premises or the public portions of the Building, shall
be placed and maintained by Tenant, at Tenant’s expense, in settings of cork, rubber, spring type or other vibration eliminators sufficient to eliminate noise
or vibration.

(22)          Tenant shall famish and install a chair mat for each desk chair located on carpet in the Leased Premises.

(23)          No solar screen materials, awnings, draperies, shutters or other interior or exterior window coverings that are visible from the exterior of
the Building or from the exterior of the Leased Premises within the Building may be installed by Tenant.  Building-standard mini blinds shall not be pulled
up or removed, but may be opened using the “wand”.

(24)          Tenant shall not place, install or operate within the Leased Premises or any other part of the Building any engine or stove, without the

prior written consent of Landlord, which consent shall not be unreasonably withheld.

(25)          No portion of the Leased Premises or any other part of the Building shall at any time be used or occupied as sleeping or lodging quarters.

(26)          For purposes of the Lease, holidays shall be deemed to mean and include the following: (a) New Year’s Day; (b) Memorial Day;

(c) Independence Day; (d) Labor Day; (e) Thanksgiving Day and the Friday following; and (f) Christmas Day.  If any such holiday occurs on a weekend,
then the holiday shall be the day such holiday is legally observed.

(27)          Tenant shall at all times keep the Leased Premises neat and orderly.

(28)          All permitted alterations and additions to the Leased Premises must conform to applicable building and fire codes.  Tenant shall obtain
prior approval from applicable building and fire officials and Landlord with respect to any such modifications and shall deliver “as-built” plans therefor to
the property manager for the Building on completion.

(29)          It is the intent of both Landlord and Tenant that any portion of the Leased Premises visible to the public hold a high quality professional

image at all times.  If, at any time during the Term, Landlord or Landlord’s agent deems such visible area to hold less than a high quality professional image,
Landlord shall advise Tenant of desired changes to be made to such area to conform to the intent of this paragraph.  Within three (3) business days, Tenant
shall cause the desired changes to be made, or present Landlord with a plan for accomplishing such changes.  Tenant shall have such additional time as is
reasonably required to implement the plan, not to exceed two (2) months; provided, however, that if Tenant is not diligently pursuing the plan for
accomplishing such changes within ten (10) business days, or does not implement the plan within two (2) months, then Landlord may provide draperies or
blinds for the glassed area at Tenant’s expense, and Tenant shall keep such draperies or blinds closed at all times.

(30)          The toilet rooms, urinals, wash bowls and other plumbing apparatus shall not be used for any purpose other than that for which they were
constructed, and no foreign substance of any kind whatsoever shall be thrown therein.  The expense of any breakage, stoppage or damage resulting from the
violation of this rule shall be borne by the tenant who, or whose employees or agents, shall have caused it.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
(31)          The Building has been designated a “non-smoking” building.  Tenant, and all persons entering the Building under the express or implied

invitation of Tenant are prohibited from smoking in the common areas both inside and outside of the Building, except in those areas outside the Building
designated as smoking areas by Landlord.

(32)          No animals, except for “service animals” trained to assist disabled persons, shall be brought or kept in or about the Leased Premises or

the Building without the prior written consent of Landlord.

(33)          Tenant shall not play or allow the playing or the generation of (i) any music or loud noise in the common areas of the Building without
Landlord’s prior written consent and/or (ii), any loud music or loud noise in the Leased Premises, as determined by Landlord in Landlord’s sole discretion.

(34)          Tenant shall not cause or allow any odors deemed obnoxious or otherwise unreasonable by Landlord, in Landlord’s sole discretion, to

permeate or emanate from the Leased Premises.

(35)          Tenant shall not bring, or cause or allow to be brought, any firearms, ammunition or weapons of any kind, whether concealed or

Tenant has not been in non-monetary default under this Lease, as evidenced by receipt of written notice from Landlord of such non-monetary default, more
than four (4) times during the Term, and (iii) Tenant is in occupancy of the Leased Premises at the time of exercise of each Renewal Option and at the time
of commencement of each Renewal Term, then Tenant is granted two (2) options (each a “Renewal Option”) to renew the Term of this Lease for two
(2) consecutive periods of three (3) additional years each (each a “Renewal Term”), to commence upon the expiration of the initial Term, and first (1st)
Renewal Term, of this Lease.  Tenant shall exercise each Renewal Option by delivering written notice of such election to Landlord at least nine (9) months
prior to the expiration of the Term, including any Renewal Term.  The renewals of this Lease shall be upon the same terms and conditions of this Lease,
except (a) the Base Rent during each Renewal Term shall be the then prevailing Market Base Rent Rate (defined below) for similar space in the Building or
Project at the time such Renewal Term commences, (b) Tenant shall have no option to renew this Lease beyond the expiration of the second (2nd) Renewal
Term, (c) Tenant shall not have the right to assign its renewal rights to any subtenant of the Leased Premises or assignee of this Lease, nor may any such
subtenant or assignee exercise such renewal rights, and (d) the leasehold improvements will be provided for Tenant’s continued use in their then existing
condition (on an “as is” basis) at the time the Renewal Term commences.

As used in this Lease, the term “Market Base Rent Rate” shall mean the prevailing annual rental rate then being charged for single-story, generic
office space comparable to other office space in the Project (taking into consideration, but not limited to, use, location and floor level within the applicable
building, definition of rentable area, leasehold improvements provided, quality and location of the applicable building, rental concessions (e.g., such as
abatements or Lease assumptions) and the time the particular rate under consideration became effective).  It is agreed that bona fide written offers to lease
the Leased Premises or comparable space made to Landlord by third parties (at arm’s-length) may be used by Landlord as an indication of Market Base
Rent Rate.

Whenever in this Lease a provision calls for a rental rate to be, or be adjusted to, the Market Base Rent Rate, Tenant shall continue to pay Base

Rent as so adjusted and the Additional Rent as provided in this Lease.

EXHIBIT H

FIRST OFFER RIGHT

As long as (i) Tenant is not in default under this Lease as defined in Section 9.02 at the time of exercise of this option or at the time of
commencement of the term for the additional space, (ii) Tenant has not been in monetary default of this Lease as defined in Section 9.02,  as evidenced by
receipt of written notice from Landlord of such monetary default, more than two (2) times during the Term, and Tenant has not been in non-monetary
default under this Lease, as evidenced by receipt of written notice from Landlord of such non-monetary default, more than four (4) times during the Term,
and (iii) Tenant is in occupancy of the Leased Premises (in the same, or greater, amount of square footage that was occupied by Tenant as of the
Commencement Date) at the time of exercise of this option and at the time of commencement of the term for the additional space, then Landlord hereby
grants to Tenant, but not any assignee or subtenant of Tenant, a right (the “First Offer Right”) during the Term to lease in its entirety any space that becomes
available that is contiguous to the Leased Premises provided that Tenant leases a minimum of 10,000 to 15,000 additional square feet in the Building (the
“Space”) that may become available (i.e., vacant) with the understanding that the configuration and total square footage contained in the Space shall be
determined by Landlord, in Landlord’s sole, but reasonable, discretion and Landlord shall notify Tenant of such configuration and square footage at the time
of Landlord’s written notice to Tenant of the availability of the Space.  Landlord shall offer the Space to Tenant at the prevailing Market Base Rent Rate
(defined below), upon the following terms and conditions:

The First Offer Right set forth herein is subject to any prior existing rights of any third parties and Landlord’s hereby reserved right to continue to

lease (by lease amendment or new lease agreement) the Space to the tenant, assignee or subtenant occupying the Space, whether or not pursuant to an option
to renew.  Landlord specifically acknowledges and agrees that, as of the Execution Date, there are no other tenants in the Project with any rights to the
Space, except for the existing tenant, International Business Machines Corporation.

1.          Prior to Landlord leasing the Space to any third party.  Landlord shall provide Tenant with written notice of the availability of the Space

and written terms of the expansion.

2.          Tenant shall then have ten (10) business days from the date of Landlord’s notice in which to respond, in writing.

3.          If Tenant elects to lease the Space, Tenant shall provide Landlord with written notice of such election within ten (10) calendar days of the

date of Landlord’s notice.  The parties shall then have thirty (30) calendar days from the date of Tenant’s notice to agree to mutually acceptable terms for
Tenant’s leasing the Space and to execute an amendment to this Lease specifying the terms of the expansion.

4.          Tenant shall accept the Space in its then-existing condition.  The term of this Lease with regard to the Space shall commence on Tenant’s
occupancy of the Space (the “Space Commencement Date”); provided, however, that in no event shall the Space Commencement Date be later than thirty
(30) calendar days after the expiration of the prior tenant’s lease.  The term of this Lease for the Space shall expire on the later of: (i) coterminously with the
Expiration Date of this Lease, as such may be amended, or (ii) three (3) years from the Space Commencement Date, in which such event the Term of this
Lease for the entire Leased Premises shall also be extended to such date.

5.          If Tenant does not respond to Landlord’s notice within such ten (10) business day period or provides Landlord with written notice that
Tenant does not elect to lease the Space, or if Landlord and Tenant, working in good-faith, fail to execute an amendment to this Lease with regard to the
Space, then the First Offer Right shall terminate with regard to the Space described in Landlord’s notice, and Landlord may thereafter lease the Space that
was described in Landlord’s notice to any third party on the terms set forth in Landlord’s notice to Tenant.  If such Space becomes available to lease at a
later date during the Term, or if Landlord does not lease such Space on the terms set forth in the notice, then Landlord must again offer such Space to Tenant
for lease, and the terms and provisions of this First Offer Right shall apply to such re-offered Space.

 
 
 
 
 
 
 
 
 
 
 
 
6.          Notwithstanding the foregoing, in the event Tenant leases the Space (either during an initial offering of such Space or a re-offering of such
Space), Tenant shall, at Tenant’s sole cost and expense, bring any remaining vacant space in the Building (the “Vacant Space”) to a similar condition to that
which existed immediately prior to Tenant’s exercise of its First Offer Right (“Leasable Condition”), including, but not limited to, (i) ensuring Leasable
Condition electrical capacity in the Vacant Space, (ii) ensuring Leasable Condition plumbing facilities (including rest rooms) in the Vacant Space,
(iii) build-out of a main entry for the Vacant Space, and (iv) any other items required by any federal, state or municipal building code for the Vacant Space
(the work done to bring the Vacant Space to a Leasable Condition shall be “Tenant’s Work in the Vacant Space”).  Subject to the aforementioned code
requirements, Landlord shall have the right to approve Tenant’s Work in the Vacant Space, with Landlord acting reasonably.

As used in this Lease, the term “Market Base Rent Rate” shall mean the annual rental rate then being charged in the greater Research Triangle

Park/Interstate-40 area of North Carolina for space comparable to the space for which the Market Base Rent Rate is being determined (taking into
consideration, but not limited to, use, location and floor level within the applicable building, definition of rentable area, leasehold improvements provided,
quality and location of the applicable building, rental concessions (e.g., such as abatements or Lease assumptions) and the time the particular rate under
consideration became effective).  It is agreed that bona fide written offers to lease the Leased Premises or comparable space made to Landlord by third
parties (at arm’s-length) may be used by Landlord as an indication of Market Base Rent Rate.

9.          Cap on TICAM Expenses.  The last three sentences of Section 4.04 (c) shall be deleted in its entirety and replaced with the following:

Notwithstanding the foregoing, commencing January 1, 2011, and for purposes of determining Tenant’s annual TICAM Expense Adjustment in
any calendar year of the Term, the TICAM Expenses which are controllable by Landlord (the “Controllable TICAM”) shall not exceed the
Controllable TICAM for the year ending December 31, 2010 (which for purposes of the annual TICAM Expense Adjustment calculation shall be
treated as the “base year”), increased at a rate of five percent (5%), compounded annually.  The limitation shall not apply to the following
expenses:  taxes, insurance, utilities, refuse collection, weather related cleanup, and any other TICAM Expense item not within Landlord’s
reasonable control (the “Uncontrollable Expenses”).  Any expenses other than Uncontrollable Expenses shall be Controllable TICAM.

10.        Tenant Improvements.  Effective as of the Execution Date, the Lease is amended by the addition of the attached Exhibit B with respect to

the fitup work in the Original Leased Premises and Expansion No. 1.

11.        Security.  Within ten (10) business days of the full execution and delivery of this Agreement, Tenant shall provide Landlord with additional

Security for the Lease in the amount of $11,000.00 and thereafter, Subsection 2.01(i) of the Lease will be changed to reflect the total Security for the Lease
as “$36,000.00”.

12.        First Offer Right.  Even though Tenant has exercised its First Offer Right with regard to the Space, Landlord shall keep the First Offer

Right set forth in Exhibit H to the Lease intact, but the “Space” shall now be as set forth on the attached, Exhibit H-l, and Tenant shall retain the option to
lease a minimum of 10,000 square feet contained in the revised Space.

13.        Brokerage/Indemnification.  Landlord and Tenant each represent to the other that they, respectively, have had no dealings with any real

estate broker or agent in connection with the negotiation of this Agreement except for Capital Associates Management, LLC, Landlord’s broker, and
Cassidy Turley, Tenant’ broker, and that they, respectively, know of no other real estate broker or agent who is entitled to a commission or finder’s fee in
connection with this Agreement.  Each party shall indemnify, protect, defend and hold harmless the other party against all claims, demands, losses,
liabilities, lawsuits, judgments, and costs and expenses (including, but not limited to, reasonable attorneys’ fees) for any leasing commission, finder’s fee or
equivalent compensation alleged to be owed on account of dealings with any other than the above-stated real estate brokers by the party from whom
indemnification is sought.  Landlord shall pay the commissions or fees due with respect to Expansion No. 1 to the above-stated Landlord’s broker. 
Landlord’s broker will then pay Tenant’s broker.

14.        Affirmation of Lease.  Except as expressly modified herein, the original terms and conditions of the Lease shall remain in full force and

effect.

15.        Binding Agreement.  Upon execution by Tenant, this Agreement shall be binding upon Tenant, its legal representatives and successors,
and, to the extent assignment may be approved by Landlord hereunder, Tenant’s assigns.  Upon execution by Landlord, this Agreement shall be binding
upon Landlord, its legal representatives, successors and assigns.  This Agreement shall inure to the benefit of Landlord and Tenant, and their respective
representatives, successors and permitted assigns.

16.        Counterparts.  This Agreement may be executed in any number of counterparts, each of which shall be an original, but all of which taken

together shall constitute one and the same instrument.

EXHIBIT B

WORKLETTER AGREEMENT

1)            Existing Condition and Expansion No. 1 Tenant Improvements.  The condition of the Original Leased Premises and Expansion No. 1 as of the date
of this Agreement, as is and with all faults, shall be deemed the “Existing Condition”.  All demolition of and improvements made to the Existing Condition
in accordance with the Schematic Space Plan and Plans (both defined below) shall be deemed the “Tenant Improvements”.

2)            Allowance.  Landlord shall provide Tenant with a tenant improvement allowance in the amount not to exceed $124,968.00 (the “Expansion
Allowance”), to pay for the costs and expenses incurred by Landlord for the design and construction of Expansion No. 1 and modifications to the design and
construction of the Original Leased Premises.  The costs and expenses shall include, but not be limited to, the costs and expenses of any (i) design and
construction services related to architectural, plumbing, mechanical and electrical trades, (ii) demolition work, (iii) construction administration services
provided by Landlord’s architect and consulting engineers, and (iv) other work necessary to demise the space.  Costs and expenses shall also include all
costs associated with any contractor’s general conditions, permits (including any new or changes to development, facility or transportation impact fees),
taxes, insurance and fees (but shall not include a construction management fee for Landlord).

3)            Design.  Landlord shall cause an architect and one or more engineers, each of whom shall be designated by Landlord and reasonably approved by
Tenant, to consult with Tenant and to prepare architectural, plumbing, mechanical and electrical plans that are (i) consistent with the “Schematic Space
Plan” for the Leased Premises (including Expansion No. 1), (ii) sufficiently detailed for pricing, approval and construction of the Tenant Improvements, and
(iii) subject to Landlord’s approval, which shall not be unreasonably withheld (the “Detailed Plans”).  All partitions, doors, hardware, ceiling tile, window
coverings, plumbing, HVAC, lighting fixtures, switches, outlets and life safety items shall be designed in Landlord’s standard manner.  Carpet, paint, and
millwork shall be selected and designed in Landlord’s standard manner and from Landlord’s standard finishes, unless otherwise agreed to by Landlord-, in
accordance with Section 4 herein.  Tenant shall furnish to Landlord all other information and technical data reasonably necessary for the preparation of the
Detailed Plans within two (2) business days of Landlord’s request therefor, or as otherwise agreed to by Tenant and Landlord, so as not to delay the design,
pricing, approval and construction of the Tenant Improvements by the Expansion No. 1 Date.  Tenant has authorized Bruce Boucher (“Tenant’s
Representative”) to represent Tenant for all purposes related to the design and construction of the Tenant Improvements, including approval of the Plans and
any Change Orders (as defined below), and approval by Tenant’s Representative shall constitute approval by Tenant.

4)            Approval of Plans and Cost.  Landlord shall cause a general contractor or contractors designated by Landlord and reasonably approved by Tenant,
to prepare detailed pricing of construction of the Tenant Improvements pursuant to the Detailed Plans.  Landlord shall submit to Tenant for Tenant’s
approval (i) the Detailed Plans and (ii) an itemized cost statement of all design and construction costs related to the Tenant Improvements (the “Cost
Statement”).  Within five (5) business days after its receipt of the Detailed Plans and Cost Statement, Tenant shall approve the Detailed Plans and the Cost
Statement in writing, subject to any modifications or changes in the Detailed Plans requested by Tenant.  Landlord, in its reasonable discretion, shall retain
final approval rights for the Detailed Plans.  After Tenant’s approval of the Detailed Plans and the Cost Statement, or in the event Tenant does not respond to
Landlord within such five (5) business day period, the Detailed Plans and the Cost Statement shall be deemed to be approved by Tenant, and the approved
Detailed Plans shall be thereafter deemed the “Plans”.  Notwithstanding anything to the contrary contained herein, if the costs and expenses of the Tenant
Improvements as approved by Tenant exceed the Expansion Allowance, then Tenant shall be obligated to pay for all such excess costs.  Landlord shall
submit an invoice to Tenant for such excess costs at the time the Detailed Plans and Cost Statement are approved or deemed approved by Tenant, and Tenant
shall pay the excess costs within fifteen (15) days of receipt of Landlord’s invoice therefor.  If the cost of designing and constructing the Tenant
Improvements as approved by Tenant is less than the Expansion Allowance, Tenant shall not be entitled to any refund of the unused portion of the
Expansion Allowance.

 
 
 
 
 
 
 
 
 
5)            Change Orders and Additional Costs.  After approval of the Cost Statement by Tenant, additional costs will likely be incurred by Landlord.  These
costs may include, without limitation, design costs that may not yet have been billed, design costs for selection of finishes, costs for construction
clarifications and other construction administration by the architect or engineers, construction changes required by governmental inspectors, and changes to
the Plans or actual construction initiated by Tenant.  From time to time, Landlord shall update the previously approved Cost Statement to account for the
subsequent changes in cost, and Tenant shall pay any cost in excess of the Expansion Allowance and not previously paid by Tenant within fifteen (15) days
of receipt of an invoice detailing such costs.  For changes initiated by Tenant that will revise the previously approved Cost Statement or the construction
schedule and increase the costs associated therewith, a change order (“Change Order”) shall be prepared by Landlord, its architect, or general contractor. 
Each Change Order shall include information regarding any revisions to the cost and construction schedule, and shall provide sufficient information for
evaluation by Landlord, its architect, and Tenant.  Before the work detailed on the Change Order proceeds, Tenant’s Representative must approve the
Change Order, including any increase in cost and time.  Tenant shall have two (2) business days to approve each Change Order, unless Landlord grants
Tenant more time.  If Tenant does not approve the Change Order within the approval period, the Change Order shall be deemed disapproved by Tenant.  If
the Change Order is not approved or deemed disapproved, Landlord shall not proceed with the work contemplated in the Change Order.  If the Change
Order is approved and the additional cost exceeds Five Thousand Dollars ($5,000.00), are in excess of the Expansion Allowance, and if requested by
Landlord, Tenant shall pay the cost of any such Change Order before Landlord proceeds with the work that is the subject of the Change Order.

6)            Construction.  After Tenant (i) approves the Detailed Plans and the Cost Statement, (or if Tenant does not respond to Landlord regarding the
Detailed Plans and the Cost Statement, as set forth in Section 4 herein), and (ii) pays any and all costs in excess of the Expansion Allowance as set forth in
Section 4 herein, then Landlord shall be entitled to cause, and shall cause, the general contractor designated by Landlord to construct the Tenant
Improvements in accordance with the Plans and the Cost Statement.

7)            Delay.  There shall be no delay in the commencement of payments of Rent with regard to Expansion No.1, even if the Tenant Improvements are
not completed by March 1, 2011.

8)            Tenant’s Access to Expansion No. 1.  Landlord shall permit Tenant and its agents reasonable access to Expansion No. 1 during normal business
hours prior to the Expansion No. 1 Date for the purpose of installing telephone and computer cabling, equipment, fixtures and other personal property, and
the entry and use of Expansion No. 1 shall not constitute acceptance of Expansion No. 1 nor Tenant’s acknowledgment of the Expansion No. 1 Date of the
Lease, unless Tenant commences the operation of any portion of its business therein.  This right of entry onto Expansion No. 1 is a license from Landlord to
Tenant which is subject to revocation in the event that Tenant or its employees, contractors or agents causes or is the cause of any code or governmental
violation, labor dispute, delay or damage during the period which results from, whether directly or indirectly, the installation or delivery of the foregoing, or
otherwise becomes in default of any term, covenant or condition of the Lease as provided in Section 9.02.  Prior to Tenant’s entry onto Expansion No. 1 in
accordance herewith, Tenant shall demonstrate to Landlord that it has obtained the insurance required and is in compliance with Section 8.04 of the Lease.

9)            Warranties.  Landlord shall cause the repair or replacement of any defects in material or workmanship in the Tenant Improvements installed by
Landlord for a period of one (1) year after the date of substantial completion of the Tenant Improvements, or the duration of any manufacturer’s warranty,
whichever is longer, provided Tenant notifies Landlord of the defect as soon as reasonably practicable after the date Tenant discovers the defect. 
LANDLORD MAKES NO WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, IN CONNECTION WITH THE TENANT IMPROVEMENTS EXCEPT AS
EXPRESSLY SET FORTH IN THIS SECTION 8.  Tenant’s sole remedy for the breach of any applicable warranty shall be the remedy set forth in this
Section 8.  Tenant agrees that no other remedy, including without limitation, incidental or consequential damages for lost profits, injury to person or
property or any other incidental or consequential loss, shall be available to Tenant.

10)          Compliance with Certain Requirements.  At any time before, during, and after construction, Landlord shall have the right to require changes to the
Plans and construction in order to comply with applicable building codes, other governmental requirements, and insurance requirements.  Neither
Landlord’s nor Tenant’s approval of the Plans is a warranty that the Plans comply with applicable building codes, other governmental requirements, and
insurance requirements.

11)          No Liability.  Notwithstanding the review and approval by Landlord of the Detailed Plans and any changes to same, Landlord shall have no
responsibility or liability, including the costs of additional or corrective work, in regard to the safety, sufficiency, adequacy or legality thereof, and Tenant
shall look solely to the party(ies) preparing same as the party(ies) responsible for ensuring that the Detailed Plans and changes thereto (and the architectural
and engineering completeness and sufficiency thereof and the Tenant Improvements constructed as a result thereof) are in compliance with all applicable
laws and regulations, and Tenant’s stated intended use.

5.             Option Term.

(a)           Option Right.  Landlord hereby grants to the originally named Tenant herein (“Original Tenant”) one (1) option to extend the Lease

Term for a period of five (5) years (the “Option Term”), which option shall be irrevocably exercised only by written notice delivered by Tenant to Landlord
not more than fifteen (15) months nor less than twelve (12) months prior to the expiration of the Second Extension Period, provided that the following
conditions (the “Option Conditions”) are satisfied: (i) as of the date of delivery of such notice, Tenant is not in default under the Lease, after the expiration
of any applicable notice and cure period; (ii) as of the end of the Second Extension Period, Tenant is not in default under the Lease, after the expiration of
any applicable notice and cure period; (iii) Tenant has not previously been in default under the Lease, after the expiration of any applicable notice and cure
period, more than twice; and (iv) the Lease then remains in full force and effect and Original Tenant or an Affiliate (as such term is defined in the Lease)
with a net worth equal to or greater than that of Original Tenant occupies the entire Premises at the time the option to extend is exercised and as of the
commencement of the Option Term.  Landlord may, at Landlord’s option, exercised in Landlord’s sole and absolute discretion, waive any of the Option
Conditions in which case the option, if otherwise properly exercised by Tenant, shall remain in full force and effect.  Upon the proper exercise of such
option to extend, and provided that Tenant satisfies all of the Option Conditions (except those, if any, which are waived by Landlord), the Lease Term, as it
applies to the Premises, shall be extended for a period of five (5) years.  The rights contained in this Section 5 shall be personal to Original Tenant, and may
be exercised by Original Tenant (and not by any assignee, sublessee or other transferee of Tenant’s interest in the Lease).

(b)           Option Rent.  The annual Rent payable by Tenant during the Option Term (the “Option Rent”) shall be equal to the “Fair Rental Value,”

as that term is defined below, for the Premises as of the commencement date of the Option Term.  The “Fair Rental Value” as used in this Section 5, shall
be equal to the annual rent per rentable square foot (including additional rent and considering any “base year” or “expense stop” applicable thereto),
including all escalations, at which tenants (pursuant to leases consummated within the twelve (12) month period preceding the first day of the Option Term),
are leasing non-sublease, non-encumbered, non-equity space which is not significantly greater or smaller in size than the subject space, for a comparable
lease term, in an arm’s length transaction, which comparable space is located in the “Comparable Buildings,” as that term is defined in this Section 5, below
(transactions satisfying the foregoing criteria shall be known as the “Comparable Transactions”), taking into consideration the following concessions (the
“Concessions”)’, (a) rental abatement concessions, if any, being granted such tenants in connection with such comparable space; (b) tenant improvements or
allowances provided or to be provided for such comparable space, and taking into account the value, if any, of the existing improvements in the subject
space, such value to be based upon the age, condition, design, quality of finishes and layout of the improvements and the extent to which the same can be
utilized by a general office user other than Tenant; and (c) other reasonable monetary concessions being granted such tenants in connection with such
comparable space; provided, however, that in calculating the Fair Rental Value, no consideration shall be given to (i) the fact that Landlord is or is not
required to pay a real estate brokerage commission in connection with Tenant’s exercise of its right to extend the Lease Term, or the fact that landlords are
or are not paying real estate brokerage commissions in connection with such comparable space, and (ii) any period of rental abatement, if any, granted to
tenants in comparable transactions in connection with the design, permitting and construction of tenant improvements in such comparable spaces.  The
Concessions (A) shall be reflected in the effective rental rate (which effective rental rate shall take into consideration the total dollar value of such
Concessions as amortized on a straight-line basis over the applicable term of the Comparable Transaction (in which case such Concessions evidenced in the
effective rental rate shall not be granted to Tenant)) payable by Tenant, or (B) at Landlord’s election, all such Concessions shall be granted to Tenant in
kind.  The term “Comparable Buildings” shall mean the Building and those other class A life sciences buildings which are comparable to the Building in
terms of age (based upon the date of completion of construction or major renovation of to the building), quality of construction, level of services and
amenities, size and appearance, and are located in Durham, North Carolina and the surrounding commercial area.

(c)           Determination of Option Rent.  In the event Tenant timely and appropriately exercises an option to extend the Lease Term, Landlord

shall notify Tenant of Landlord’s determination of the Option Rent on or before the Lease Expiration Date.  If Tenant, on or before the date which is ten
(10) days following the date upon which Tenant receives Landlord’s determination of the Option Rent, in good faith objects to Landlord’s determination of
the Option Rent, then Landlord and Tenant shall attempt to agree upon the Option Rent using their best good-faith efforts.  If Landlord and Tenant fail to
reach agreement within ten (10) days following Tenant’s objection to the Option Rent (the “Outside Agreement Date”), then each party shall make a
separate determination of the Option Rent, as the case may be, within five (5) days, and such determinations shall be submitted to arbitration in accordance
with the provisions below.  If Tenant fails to object to Landlord’s determination of the Option Rent within the time period set forth herein, then Tenant shall
be deemed to have objected to Landlord’s determination of Option Rent.

2

 
 
 
 
 
 
(i)            Landlord and Tenant shall each appoint one arbitrator who shall be, at the option of the appointing party, a real estate broker,

appraiser or attorney who shall have been active over the five (5) year period ending on the date of such appointment in the leasing or appraisal, as the case
may be, of other class A life sciences buildings located in the Durham, North Carolina market area.  The determination of the arbitrators shall be limited
solely to the issue of whether Landlord’s or Tenant’s submitted Option Rent is the closest to the actual Option Rent, taking into account the requirements
above, as determined by the arbitrators.  Each such arbitrator shall be appointed within fifteen (15) days after the Outside Agreement Date.  Landlord and
Tenant may consult with their selected arbitrators prior to appointment and may select an arbitrator who is favorable to their respective positions.  The
arbitrators so selected by Landlord and Tenant shall be deemed “Advocate Arbitrators.”

(ii)           The two (2) Advocate Arbitrators so appointed shall be specifically required pursuant to an engagement letter within ten

(10) days of the date of the appointment of the last appointed Advocate Arbitrator to agree upon and appoint a third arbitrator (“Neutral Arbitrator”) who

TENANT WORK LETTER

This Tenant Work Letter is attached as an Exhibit to that certain Fourth Amendment to Lease Agreement (the “Amendment”) between DURHAM KTP
TECH 4, LLC, as Landlord, and LIQUIDIA TECHNOLOGIES, INC., as Tenant, that amends that certain Lease Agreement dated June 29, 2007 (as
amended, the “Lease”) and relating to the lease by Landlord to Tenant of that certain Premises.  Unless otherwise specified, all capitalized terms used in this
Work Letter shall have the same meanings as in the Lease as amended by the Amendment.

1.   Construction.  Tenant agrees to construct leasehold improvements (the “Tenant Work”) in a good and workmanlike manner in and upon the Premises, at
Tenant’s sole cost and expense, in accordance with the following provisions.  Prior to construction, Tenant shall submit to Landlord for Landlord’s approval
complete plans and specifications for the construction of the Tenant Work (“Tenant’s Plans”).  Within 10 business days after receipt of Tenant’s Plans,
Landlord shall review and either approve or disapprove Tenant’s Plans.  If Landlord disapproves Tenant’s Plans, or any portion thereof, Landlord shall
notify Tenant thereof and of the revisions Landlord requires before Landlord will approve Tenant’s Plans.  Within 10 business days after Landlord’s notice,
Tenant shall submit to Landlord, for Landlord’s review and approval, plans and specifications incorporating the required revisions.  The final plans and
specifications approved by Landlord are hereinafter referred to as the “Approved Construction Documents”.  Tenant will employ experienced, licensed
contractors, architects, engineers and other consultants, approved by Landlord, to construct the Tenant Work and will require in the applicable contracts that
such parties (a) carry insurance in such amounts and types of coverages as are reasonably required by Landlord, (b) list the Landlord and its partners as
additional insureds, and (c) design and construct the Tenant Work in a good and workmanlike manner and in compliance with all laws.  Unless otherwise
agreed to in writing by Landlord and Tenant, all work involved in the construction and installation of the Tenant Work shall be carried out by Tenant’s
contractor under the sole direction of Tenant, in compliance with all Building rules and regulations and in such a manner so as not to unreasonably interfere
with or disturb the operations, business, use and enjoyment of the Project by other tenants in the Building or the structural calculations for imposed loads. 
Tenant shall obtain from its contractors and provide to Landlord a list of all subcontractors providing labor or materials in connection with any portion of the
Tenant Work prior to commencement of the Tenant Work.  Tenant warrants that the design, construction and installation of the Tenant Work shall conform
to the requirements of all applicable laws, including building, plumbing and electrical codes and parameters, and the requirements of any authority having
jurisdiction over, or with respect to, such Tenant Work.

2.   Costs.  Subject to the terms and conditions of this Section 2, Landlord will provide Tenant with an allowance (the “Reimbursement Allowance”) to be
applied towards the cost of constructing the Tenant Work.

(A) Landlord’s obligation to reimburse Tenant for Tenant’s construction of the Tenant Work shall be: (i) limited to actual costs incurred by Tenant in its
construction of the Tenant Work; (ii) limited to an amount up to, but not exceeding, $10.00 multiplied by the rentable square footage of the Premises; and
(iii) conditioned upon Landlord’s receipt of written notice (which notice shall be accompanied by invoices and documentation set forth below) from Tenant
that the Tenant Work has been completed and accepted by Tenant.  The cost of (a) all space planning, design, consulting or review services and construction
drawings, (b) extension of electrical wiring from Landlord’s designated location(s) to the Premises, (c) purchasing and installing all building equipment for
the Premises (including any submeters and other above building standard electrical equipment approved by Landlord), (d) required metering, re-circuiting
or re-wiring for metering, equipment rental, engineering design services, consulting services, studies, construction services, cost of billing and collections,
(e) materials and labor, (f) a 1% project management fee as outlined below in Section 4, payable to Landlord or its affiliates on total construction costs, and
(g) an asbestos survey of the Premises if required by applicable law, shall all be included in the cost of the Tenant Work and may be paid out of the
Reimbursement Allowance, to the extent sufficient funds are available for such purpose.  Any reimbursement obligation of Landlord under this Work Letter
shall be applied solely to the purposes specified above, as allocated, within 365 days after the Effective Date or be forfeited with no further obligation on the
part of Landlord.

 
 
 
 
 
 
 
 
 
(B) Landlord shall pay the Reimbursement Allowance to Tenant within 45 days following Landlord’s receipt of (i) third-party invoices for costs incurred by
Tenant in constructing the Tenant Work; (ii) evidence that Tenant has paid the invoices for such costs; and (iii) final lien waivers from any contractor or
supplier who has constructed or supplied materials for the Tenant Work.  If the costs incurred by Tenant in constructing the Tenant Work exceed the
Reimbursement Allowance, then Tenant shall pay all such excess costs and Tenant agrees to keep the Premises and the Project free from any liens arising
out of the non-payment of such costs,

(C) All installations and improvements now or hereafter placed in the Premises other than building standard improvements shall be for Tenant’s account and
at Tenant’s cost.  Tenant shall pay ad valorem taxes and increased insurance thereon or attributable thereto, which cost shall be payable by Tenant to
Landlord as additional Rent within 30 days after receipt of an invoice therefor.  Tenant’s failure to pay such cost shall constitute an event of default under
the Lease.

3.   ADA Compliance.  Landlord shall not be responsible for determining whether Tenant is a public accommodation under ADA or whether the Approved
Construction Documents comply with ADA requirements.  Such determinations, if desired by Tenant, shall be the sole responsibility of Tenant.  Landlord’s
approval of the Approved Construction Documents shall not be deemed a statement of compliance with applicable Laws, nor of the accuracy, adequacy,
appropriateness, functionality or quality of the improvements to be made according to the Approved Construction Documents.

4.   Landlord’s Oversight and Coordination.  Construction of the Tenant Work shall be subject to oversight and coordination by Landlord, but such oversight
and coordination shall not subject Landlord to any liability to Tenant, Tenant’s contractors or any other person.  Landlord has the right to inspect
construction of the Tenant Work from time to time.  A 1% project management fee shall be payable to Landlord or its affiliates by Tenant on total
construction costs which amount Landlord may pay from the available Reimbursement Allowance.

5.   Assumption of Risk and Waiver.  Tenant hereby assumes any and all risks involved with respect to the Tenant Work and hereby releases and discharges
all Landlord parties from any and all liability or loss, damage or injury suffered or incurred by Tenant or third parties in any way arising out of or in
connection with the Tenant Work.

4.          Condition of Premises. TENANT ACCEPTS THE PREMISES IN ITS “AS-IS”  CONDITION AND CONFIGURATION, AND WITHOUT
ANY REPRESENTATIONS OR WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, BY LANDLORD REGARDING THE PREMISES

CONDITION. However, any necessary construction of leasehold improvements shall be accomplished and the cost of such construction shall be paid in
accordance with the “Work Letter” between Landlord and Tenant attached to this Amendment as Exhibit A.

5.          Additional Security Deposit. Within ten (I 0) days after the Fina1 Financing Date, as defined below, so long as this Amendment is not terminated
in accordance with Section 6 below Tenant shall post an additional $261,717.24 (the “Supplemental Security Deposit’) to the already existing Security
Deposit of $36,000 under the Lease and the total Security Deposit shall be equal to $297,717.24 So long as Tenant is not in default under the Lease beyond
applicable notice and cure periods, the Security Deposit shall be reduced by $74,429.31 on the date Tenant completes the initial public offering for the stock
of Tenant and provides proof of such completed transaction to Landlord (the “IPO Date”). Additionally, so long as Tenant is not in default under the Lease
beyond applicable notice and cure periods, the Security Deposit shall be reduced by an additional $74,429.31 on the date which is three (3) years after the
IPO Date so long as Tenant’s financial position is equal to or greater than Tenant’s financial position as of the IPO Date. For clarity, in both instances above
with respect to Security Deposit reduction, Landlord shall return the said amounts to Tenant within thirty (30) days of Tenant providing Landlord with
sufficient written notice of satisfaction of said condition.

Landlord shall not be required to fund any portion of the Reimbursement Allowance, as defined in Exhibit A, until Tenant has posted the

Supplemental Security Deposit with Landlord.

6.          Contingency. This Amendment is contingent upon Tenant’s receipt of financing from its Bridge financing (the “Financing”). In the event Tenant
does not finalize the Financing on or before January 31, 2017 (the “Final Financing Date”) then either Tenant or Landlord may terminate this Amendment
upon written notice to Landlord which notice must be given to the other party on or before February 10, 2017. If neither party provides such notice by the
required date this Amendment shall continue in full force and effect and this Section 6 shall be deemed deleted from this Amendment. In addition to any
other limitations on funding the Reimbursement Allowance, Landlord shall not be required to provide any of the Reimbursement Allowance to Tenant until
Tenant obtains the Financing or until this Section 6 is deemed deleted from this Amendment.

7.          Broker. Each party represents and warrants to the other that it has not been represented by any broker or agent in connection with the execution of
this Amendment, other than Longfellow Brokerage Services NC, LLC as Landlord’s agent, and Foundry Commercial, as Tenant’s agent Each party shall
indemnify the other and their respective partners, members, affiliates and subsidiaries, and all of their respective officers, directors, shareholders,
employees, servants, partners, members, representatives, insurers and agents from and against all claims (including costs of defense and investigation)

Amendment), the Existing Premises shall be expanded by adding the Expansion Premises and the term “Premises” under the Lease shall be redefined to be
the Existing Premises plus the Expansion Premises, totaling approximately 45,095 rentable square feet of space (the “Revised Premises”).

Lease Term; Renewal Options.  Effective  as  of  the  Effective  Date,  the  Term  of  the  Lease  for  the  Expansion  Space  (the  “Expansion  Premises
Term”) shall be co-terminus with the Term of the Lease with respect to the Existing Premises, which shall expire on October 31, 2026, subject to Tenant’s
options to extend the Term of the Lease pursuant to Section 5 of the Fourth Amendment which right shall apply to the entire Revised Premises.

TENANT WORK LETTER

This Tenant Work Letter sets forth the terms and conditions relating to the construction of improvements in the Expansion Premises. All references
in  this  Tenant  Work  Letter  to  Articles  or  Sections  of  “this  Expansion  Premises  Amendment”  shall  mean  the  relevant  portion  of  the  Expansion  Premises
Amendment to which this Tenant Work Letter is attached as Exhibit A and of which this Tenant Work Letter forms a part, and all references in this Tenant
Work Letter to Sections of “this Tenant Work Letter” shall mean the relevant portion of this Tenant Work Letter.

1.           LANDLORD’S CONSTRUCTION IN THE EXPANSION PREMISES

1.1     Landlord Work. None.

2.           TENANT IMPROVEMENTS

2.1     Tenant Improvements Allowance. Tenant shall be entitled to a tenant improvement allowance (the “Tenant Improvements Allowance”) in the
maximum aggregate amount of $950,360.00 (i.e., $115.00 per rentable square foot of the Expansion Premises) (the “Maximum Allowance Amount”) for the
hard costs and customary soft costs incurred by Tenant including, without limitation out-of-pocket architectural and engineering fees and a one and one-half
percent (1.5%) project management fee payable to Landlord or its affiliates and permits, relating to the design and construction of Tenant’s improvements
which  are  to  be  permanently  affixed  to  the  Expansion  Premises  (the  “Tenant Improvements”).  In  no  event  shall  Tenant  be  permitted  to  use  any  excess
Tenant Improvements Allowance toward the Base Rent or any soft costs that are not directly related to the design and construction within the Expansion
Premises. In no event shall Landlord be obligated to make disbursements pursuant to this Tenant Work Letter in a total amount which exceeds the Maximum
Allowance Amount. All Tenant Improvements for which the Tenant Improvements Allowance has been made available shall be deemed Landlord’s property
under  the  terms  of  the  Lease.  Tenant  must  fully  utilize  the  Tenant  Improvements  Allowance  within  twelve  (12)  months  after  the  Effective  Date  of  this
Expansion Premises Amendment (such period to be extended by any delays caused by Landlord, its agents, employees, architects and/or contractors in the
development  and  approval  of  the  final  space  plan  and/or  the  construction  documents  and/or  delays  in  the  submission  and  pursuit  of  permits  and  the
construction  of  the  Tenant  Improvements,  provided,  however,  Tenant  shall  notify  Landlord  in  writing  of  the  claimed  estimated  length  of  such  Landlord
delay within ten (10) business days after its occurrence and Landlord may elect by written notice delivered to Tenant within ten (10) business days thereafter
to dispute the claimed estimated Landlord delay) and any amounts unutilized by such date shall be deemed forfeited by Tenant.

2.2     Disbursement of the Tenant Improvements Allowance. Except as otherwise set forth in this Tenant Work Letter, the Tenant Improvements
Allowance shall be disbursed by Landlord (each of which disbursements shall be made pursuant to Landlord’s reasonable disbursement process) for costs
incurred by Tenant related to the construction of the Tenant Improvements and for the following items and costs (collectively, the “Tenant Improvements
Allowance Items”):  (i)  payment  of  the  fees  of  the  “Architect”  as  that  term  is  defined  in  Section 3.1  of  this  Tenant  Work  Letter  in  connection  with  the
preparation  and  review  of  the  “Construction Documents,”  as  that  term  is  defined  in  Section 3.1  of  this  Tenant  Work  Letter;  (ii)  payment  of  the  project
management fee described above, (iii) the cost of any changes to the Construction Documents or Tenant Improvements required by all applicable building
codes (the “Code”) enacted after approval of the Construction Documents, (iv) costs payable to the Contractor and any subcontractors, and (v) other costs
incurred in connection with the Tenant Improvements to the extent the same can be paid using the Tenant Improvements Allowance pursuant to the specific
provisions of this Tenant Work Letter.

B-1

 
 
 
 
 
 
 
 
 
 
Once Landlord is required to disburse any portion of the Tenant Improvement Allowance as noted above, Landlord shall disburse the applicable
portion  of  the  Tenant  Improvements  Allowance  within  thirty  (30)  calendar  days  of  a  Payment  Request  (as  hereinafter  defined),  an  amount  equal  to  the
portion of the actual costs and expenses Tenant has incurred and paid in connection with the construction of the Tenant Improvements to date, which are to
be paid for from the Tenant Improvement Allowance provided the following conditions have been satisfied:

specifying the work which has been completed; and

(1)     Tenant has delivered to Landlord a payment request (“Payment Request”) in a form reasonably satisfactory to Landlord

substantially in the form of AIA Document G702 and AIA Document G703; and

(2)          Tenant’s  general  contractor  and/or  architect  shall  have  submitted  an  application  for  payment  and  sworn  statement

(3)     Tenant has submitted to Landlord lien waivers or partial lien waivers from all contractors, subcontractors, artchitects, and
materialmen who performed such work to cover the work included under the Payment Request and all prior work Tenant was required to pay for before
utilizing the Tenant Improvements Allowance.

Notwithstanding anything herein to the contrary, the Tenant Improvements Allowance must be requested by Tenant, if at all, in accordance with
this paragraph on or before the date that is one (1) year following the Effective Date of this Expansion Premises Amendment, and any portion not requested
by such date may no longer be utilized by Tenant and shall be deemed forfeited to Landlord.

3.           CONSTRUCTION DOCUMENTS

3.1     Selection of Architect/Construction Documents. Tenant shall retain Integrated Designs, PA (collectively, the “Architect”) as subcontractors
to prepare the “Construction Documents,” as that term is defined in this Section 3.1 for the Tenant Improvements, together with the consulting engineers
selected by the Architect and reasonably approved by Landlord. Tenant may retain another Architect or Architects from time to time, provided, however,
that any such other Architects shall be subject to Landlord’s reasonable approval. The plans and drawings to be prepared by Architect hereunder shall be
known collectively as the “Construction Documents.” All Construction Documents shall comply with the drawing format and specifications as determined
by  Landlord,  and  shall  be  subject  to  Landlord’s  and  Tenant’s  approval.  Landlord  may  hire  an  architectural  firm  to  conduct  a  peer  review,  and  the  fees
associated with this peer review shall be paid from the Tenant Improvements Allowance.

Landlord has no obligation to approve any Tenant Change or any Tenant Improvements not shown on the plans previously approved by Landlord
and Tenant or reasonably inferable therefrom if, in Landlord’s reasonable judgment, such Tenant Improvements (i) would materially increase the cost of
performing  any  other  work  in  the  Building,  unless  in  each  case  Tenant  agrees  to  pay  such  costs  based  on  Tenant’s  Change  Estimate  Notice  (as  defined
below), (ii) are incompatible with the design, quality, equipment or systems of the Building or otherwise require a change to the existing Building systems
or structure, each in a manner that would not otherwise be required in connection with the improvements contemplated by the Fit Plan (as defined below),
(iii) is not consistent the first class nature of the Building, or (iv) otherwise do not comply with the provisions of the Lease.

3.2     Final Space Plan. Tenant has approved the preliminary space plan prepared by the Architect attached as Attachment 1 hereto (the “Fit Plan”).
Tenant  shall  use  commercially  reasonable  efforts  to  cause  the  Architect  to  prepare  a  space  plan  for  the  Expansion  Premises  which  space  plan  shall  be
reasonably consistent with the Fit Plan and shall include a layout and designation of all labs, offices, rooms and other partitioning, their intended use, and
equipment  to  be  contained  therein,  and  shall  deliver  the  space  plan  to  Landlord  and  Tenant  for  their  approval.  Landlord  shall  review  and  provide  any
changes to the space plan within five (5) business days of receipt thereof. Once Landlord and Tenant approve the final space plan, the space plan shall be
considered final (the “Final Space Plan”).

3.3     Construction Documents. Tenant shall cause the Architect to complete final Construction Documents consistent with the Final Space Plan
and shall submit the same to Landlord and Tenant for their approval. Landlord shall review and provide any changes to the construction documents within
five  (5)  business  days  of  receipt  thereof,  and  the  Tenant  shall  use  reasonable  efforts  to  cause  the  Architect  to  prepare  and  circulate  modified  documents
within ten (10) business days of its receipt of any requested changes from Tenant or Landlord. Such process of submittal and response within the time frame
specified  in  the  preceding  sentence  shall  continue  until  each  of  Landlord  and  Tenant  gives  written  approval  to  such  documents,  and  the  Construction
Documents shall be considered final once approved by the Landlord and the Tenant. In no event may either Tenant or Landlord require any changes that are
inconsistent with the Final Space Plan. The Construction Documents shall comply with applicable laws existing on the date of this Tenant Work Letter and
which may be enacted prior to approval of completed Construction Documents. Subject to the provisions of Sections 3.1 and 5.4 of this Tenant Work Letter,
Tenant  may,  from  time  to  time,  by  written  request  to  Landlord  on  a  form  reasonably  specified  by  Landlord  (“Tenant Change”),  request  a  change  in  the
Tenant Improvements shown on the Construction Documents, which approval shall not be unreasonably withheld or conditioned, and shall be granted or
denied within five (5) business days after delivery of such Tenant Change to Landlord.

3.4          Permits.  The  Construction  Documents  as  approved  (or  deemed  approved)  pursuant  to  Section  3.3  shall  be  the  “Approved  Working
Drawings”.  Following  approval  or  deemed  approval  of  the  Cost  Proposal,  as  described  below,  Tenant  shall  promptly  thereafter  submit  or  cause  to  be
submitted, the Approved Working Drawings to the appropriate municipal authorities for all applicable building permits necessary to allow “Contractor,” as
that term is defined in Section 4.1, below, to commence and fully complete the construction of the applicable Tenant Improvements (the “Permits”).

4.           CONSTRUCTION OF THE TENANT IMPROVEMENTS

4.1     Contractor. A contractor designated by Tenant and approved by Landlord (“Contractor”) shall construct the Tenant Improvements.

4.2     Cost Proposal.  After  the  Approved  Working  Drawings  are  approved  by  Landlord  and  Tenant,  Tenant  shall  provide  Landlord  with  a  cost
proposal (or cost proposals) in accordance with the Approved Working Drawings, which cost proposal(s) shall include, as nearly as possible, the cost of all
Tenant  Improvements  Allowance  Items  to  be  incurred  by  Tenant  in  connection  with  the  design  and  construction  of  the  Tenant  Improvements  and  shall
include a so-called guaranteed maximum price proposal from Tenant’s Contractor (collectively, the “Cost Proposal”),  which  Cost  Proposal  shall  include,
among other things, the Contractor’s fee, general conditions, and a reasonable contingency. The Cost Proposal may include early trade release packages for
long lead time matters such as mechanical equipment. In connection with the Cost Proposal, Tenant shall cause the Contractor to solicit at least three (3)
bids from each subcontractor trade for which the total cost is expected to exceed $10,000.00. Landlord may review bid packages at Landlord’s request. In
the case of each bid request, Tenant will accept the lowest responsible bid, unless Landlord and Tenant reasonably determine otherwise.

4.3.2          Tenant’s  Retention  of  Contractor.  Tenant  shall  independently  retain  Contractor  to  construct  the  Tenant  Improvements  in
accordance  with  the  applicable  Approved  Working  Drawings  and  the  applicable  Cost  Proposal.  Landlord  shall  be  entitled  to  review  the  Tenant’s
construction contract with the Contractor upon Landlord’s written request. Tenant shall manage the Contractor in its performance of the construction work
and endeavor to oversee the Contractor’s performance of its work to protect Landlord from construction defects.

5.           COMPLETION OF THE TENANT IMPROVEMENTS

5.1          Substantial  Completion.  Tenant  shall  give  Landlord  at  least  twenty  (20)  days  prior  written  notice  of  the  date  that  Tenant  reasonably
anticipates  that  the  Tenant  Improvements  will  be  Substantially  Complete  (as  defined  below).  For  purposes  of  this  Lease,  “Substantial Completion” shall
occur  upon  the  completion  of  construction  of  the  Tenant  Improvements  substantially  pursuant  to  the  Approved  Working  Drawings  for  such  Tenant
Improvements (each as reasonably determined by Landlord), with the exception of any punch list items.

5.2     Intentionally omitted.

5.3     Intentionally omitted.

5.4     Tenant Changes. Landlord may, but shall not be obligated to, approve any Tenant Change on the condition that Tenant shall pay in full, in
advance (or cause to be paid in full from the Tenant Improvements Allowance), any and all additional costs or expenses associated with the approval of said
Tenant Change. If Tenant shall request any Tenant Change, Tenant shall provide Landlord in writing (a “Tenant’s Change Estimate Notice”) the estimated
costs of design and/or construction of the Tenant Improvements that Tenant determines will be incurred as a consequence of such Tenant Change on an
order of magnitude basis on account of such proposed Tenant Change. The cost of any Tenant Change shall be determined on a net basis; i.e. taking into
account the savings, if any, resulting from such Tenant Change.

5.5     Delay Not Caused by Parties. Neither the Landlord nor Tenant shall be considered to be in default of the provisions of this Tenant Work

Letter for delays in performance due to Force Majeure.

CERTIFICATION OF THE PRINCIPAL FINANCIAL OFFICER

PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, Richard D. Katz, M.D., certify that:

1.

I have reviewed this Annual Report on Form 10-K of Liquidia Technologies, Inc.;

Exhibit 31.2

2. Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the
statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this
report;

3. Based on my knowledge, the financial statements, and other financial information included in this report, fairly present in all material respects the

financial condition, results of operations and cash flows of the registrant as of, and for, the periods presented in this report;

4. The  registrant’s  other  certifying  officer  and  I  are  responsible  for  establishing  and  maintaining  disclosure  controls  and  procedures  (as  defined  in
Exchange  Act  Rules  13a-15(e)  and  15d-15(e))  and  internal  control  over  financial  reporting  (as  defined  in  Exchange  Act  Rules  13a-15(f)  and
15(d)-15(f)) for the registrant and have:

a) Designed such disclosure controls and procedures, or caused such disclosure controls and procedures to be designed under our supervision,
to ensure that material information relating to the registrant, including its consolidated subsidiaries, is made known to us by others within
those entities, particularly during the period in which this report is being prepared;

b) Designed such internal control over financial reporting, or caused such internal control over financial reporting to be designed under our
supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for
external purposes in accordance with generally accepted accounting principles;

c) Evaluated  the  effectiveness  of  the  registrant’s  disclosure  controls  and  procedures  and  presented  in  this  report  our  conclusions  about  the
effectiveness of the disclosure controls and procedures, as of the end of the period covered by this report based on such evaluation; and

d) Disclosed  in  this  report  any  change  in  the  registrant’s  internal  control  over  financial  reporting  that  occurred  during  the  registrant’s  most
recent fiscal quarter (the registrant’s fourth fiscal quarter in the case of an annual report) that has materially affected, or is reasonably likely
to materially affect, the registrant’s internal control over financial reporting; and

5. The registrant’s other certifying officer and I have disclosed, based on our most recent evaluation of internal control over financial reporting, to

the registrant’s auditors and the audit committee of the registrant’s board of directors (or persons performing the equivalent functions):

a) All  significant  deficiencies  and  material  weaknesses  in  the  design  or  operation  of  internal  control  over  financial  reporting  which  are

reasonably likely to adversely affect the registrant’s ability to record, process, summarize and report financial information; and

b) Any fraud, whether or not material, that involves management or other employees who have a significant role in the registrant’s internal

control over financial reporting.
