OVERVIEW

Celsion  is  an  integrated  development  clinical  stage  oncology  drug  company  focused  on  advancing  innovative  cancer  treatments,  including  directed
chemotherapies,  DNA-mediated  immunotherapy  and  RNA-based  therapies.  Our  lead  product  candidate  is  ThermoDox®,  a  proprietary  heat-activated
liposomal encapsulation of doxorubicin, currently in a Phase III clinical trial for the treatment of primary liver cancer (the “OPTIMA Study”). Second in
our product pipeline is GEN-1, a DNA-mediated immunotherapy for the localized treatment of ovarian cancer. These investigational products are based on
platform technologies that provide the basis for future development of a range of therapeutics, largely focused on difficult-to-treat forms of cancer. The first
platform  technology  is  Lysolipid  Thermally  Sensitive  Liposomes,  a  heat  sensitive  liposomal  based  dosage  form  that  is  designed  to  target  disease  with
known chemotherapeutics in the presence of mild heat. The second platform technology is TheraPlas, a novel nucleic acid-based investigational candidate
under development for local transfection of therapeutic DNA plasmids. Employing these technologies, we are working to develop and commercialize more
efficient, effective and targeted oncology therapies that maximize efficacy while minimizing side effects common to cancer treatments.

THERMODOX®

Liposomes are manufactured submicroscopic vesicles consisting of a discrete aqueous central compartment surrounded by a membrane bilayer composed
of naturally occurring lipids. Conventional liposomes have been designed and manufactured to carry drugs and increase residence time, thus allowing the
drugs  to  remain  in  the  bloodstream  for  extended  periods  of  time  before  they  are  removed  from  the  body.  However,  the  current  existing  liposomal
formulations of cancer drugs and liposomal cancer drugs under development do not provide for the immediate release of the drug and the direct targeting of
organ specific tumors, two important characteristics that are required for improving the efficacy of cancer drugs such as doxorubicin. A team of research
scientists at Duke University developed a heat-sensitive liposome that rapidly changes its structure when heated to a threshold minimum temperature of
39.5º  to  42º  Celsius.  Heating  creates  channels  in  the  liposome  bilayer  that  allow  an  encapsulated  drug  to  rapidly  disperse  into  the  surrounding  tissue.
Through a perpetual, world-wide, exclusive development and commercialization license from Duke University, we have licensed this novel, heat-activated
liposomal technology that is differentiated from other liposomes through its unique low heat-activated release of encapsulated chemotherapeutic agents.

We  are  able  to  use  several  available  focused-heat  technologies,  such  as  radiofrequency  ablation  (“RFA”),  microwave  energy  and  high  intensity  focused
ultrasound (“HIFU”), to activate the release of drugs from our novel heat sensitive liposomes.

THERMODOX® for the Treatment of Primary Liver Cancer

Primary Liver Cancer Overview

Hepatocellular carcinoma (“HCC”) is one of the most common and deadliest forms of cancer worldwide. It ranks as the third most common solid tumor
cancer. It is estimated that up to 90% of liver cancer patients will die within five years of diagnosis. The incidence of primary liver cancer is approximately
35,000  cases  per  year  in  the  U.S.,  approximately  65,000  cases  per  year  in  Europe  and  is  increasing  at  approximately  2-3%  per  year  worldwide.  Global
incidence  (per  2017  GLOBALCAN  statistics)  is  reported  at  755,000  cases.  The  World  Health  Organization  (WHO)  has  projected  that  HCC  will  be  the
most prevalent form of cancer by 2030. HCC is commonly diagnosed in patients with longstanding hepatic disease and cirrhosis (primarily due to hepatitis
C in the U.S., Japan and Europe and hepatitis B in Asia).

At an early stage, the standard first line treatment for liver cancer is surgical resection of the tumor. Up to 80% of patients are ineligible for surgery or
transplantation at time of diagnosis because early stage liver cancer generally has few symptoms and when finally detected the tumor frequently is too large
for surgical resection. There are few alternative treatments, since radiation therapy and chemotherapy are largely ineffective in treating liver cancer. For
tumors generally up to 5 centimeters in diameter, RFA has emerged as the standard of care treatment which directly destroys the tumor tissue through the
application of high temperatures administered by a probe inserted into the core of the tumor. Local recurrence rates after RFA directly correlate to the size
of the tumor. For tumors 3 cm or smaller in diameter the recurrence rate has been reported to be 10 – 20%; however, for tumors greater than 3 cm, local
recurrence rates of 40% or higher have been observed.

Celsion’s Approach

While RFA uses extremely high temperatures (greater than 90° Celsius) to ablate the tumor, it may fail to treat micro-metastases in the outer margins of the
ablation zone because temperatures in the periphery may not be high enough to destroy cancer cells. Our ThermoDox® treatment approach is designed to
utilize  the  ability  of  RFA  devices  to  ablate  the  center  of  the  tumor  while  simultaneously  thermally  activating  our  ThermoDox®  liposome  to  release  its
encapsulated  doxorubicin  to  kill  any  remaining  viable  cancer  cells  throughout  the  heated  region,  including  the  ablation  margins.  This  novel  treatment
approach  is  intended  to  deliver  the  drug  directly  to  those  cancer  cells  that  survive  RFA.  This  approach  is  designed  to  increase  the  delivery  of  the
doxorubicin at the desired tumor site while potentially reducing drug exposure distant to the tumor site.

The OPTIMA Study

The OPTIMA Study represents an evaluation of ThermoDox® in combination with a first line therapy, RFA, for newly diagnosed, intermediate stage HCC
patients. HCC incidence globally is approximately 755,000 new cases per year and is the third largest cancer indication globally. Approximately 30% of
newly diagnosed patients can be addressed with RFA.

On February 24, 2014, we announced that the United States Food and Drug Administration (the “FDA”) provided clearance for the OPTIMA Study, which
is  a  pivotal,  double-blind,  placebo-controlled  Phase  III  trial  of  ThermoDox®,  in  combination  with  standardized  RFA,  for  the  treatment  of  primary  liver
cancer. The trial design of the OPTIMA Study is based on the comprehensive analysis of data from an earlier clinical trial conducted by the Company
called  the  HEAT  Study  (the  “HEAT  Study”). The  OPTIMA  Study  is  supported  by  a  hypothesis  developed  from  an  overall  survival  analysis  of  a  large
subgroup of 285 patients from the HEAT Study.

Post-hoc data analysis from our earlier Phase III HEAT Study suggest that ThermoDox® may substantially improve OS, when compared to the control
group, in patients if their lesions undergo a 45-minute RFA procedure standardized for a lesion greater than 3 cm in diameter. Data from nine OS sweeps
have been conducted since the top line progression free survival (“PFS”) data from the HEAT Study were announced in January 2013, with each data set
demonstrating substantial improvement in clinical benefit over the control group with statistical significance. On August 15, 2016, we announced updated
results from its final retrospective OS analysis of the data from the HEAT Study (the “HEAT Study subgroup”). These results demonstrated that in a large,
well  bounded,  subgroup  of  patients  with  a  single  lesion  (n=285,  41%  of  the  HEAT  Study  patients),  treatment  with  a  combination  of  ThermoDox®  and
optimized RFA provided an average 54% risk improvement in OS compared to optimized RFA alone. The Hazard Ratio (“HR”) at this analysis is 0.65
(95% CI 0.45 - 0.94) with a p-value of 0.02. Median OS for the ThermoDox® subgroup has been reached which translates into a two-year survival benefit
over the optimized RFA subgroup (projected to be greater than 80 months for the ThermoDox® plus optimized RFA subgroup compared to less than 60
months projection for the optimized RFA only subgroup).

While this information should be viewed with caution since it is based on a retrospective analysis of a subgroup, we also conducted additional analyses that
further strengthen the evidence for the HEAT Study subgroup. We commissioned an independent computational model at the University of South Carolina
Medical School. The results unequivocally indicate that longer RFA heating times correlate with significant increases in doxorubicin concentration around
the  RFA  treated  tissue.  In  addition,  we  conducted  a  prospective  preclinical  study  in  22  pigs  using  two  different  manufacturers  of  RFA  and  human
equivalent doses of ThermoDox® that clearly support the relationship between increased heating duration and doxorubicin concentrations.

The OPTIMA Study was designed with extensive input from globally recognized HCC researchers and expert clinicians. The FDA also provided formal
written  feedback  to  the  Company  on  the  study  protocol  and  trial  design.  The  OPTIMA  Study  was  designed  to  enroll  up  to  550  patients  globally  at
approximately  65  clinical  sites  in  the  U.S.,  Canada,  European  Union  (EU),  China  and  other  countries  in  the  Asia-Pacific  region  and  will  evaluate
ThermoDox® in combination with standardized RFA, which will require a minimum of 45 minutes across all investigators and clinical sites for treating
lesions three to seven centimeters, versus standardized RFA alone. The primary endpoint for this clinical trial is overall survival (“OS”), and the secondary
endpoints  are  progression  free  survival  and  safety.  The  statistical  plan  calls  for  two  interim  efficacy  analyses  by  an  independent  Data  Monitoring
Committee (“DMC”).

We completed enrollment of 556 patients in the Phase III OPTIMA Study in August 2018. Data for the study will be reviewed as it matures with up to two
interim analyses - the first analysis was conducted in the second half of 2019 and the second analysis is expected to be conducted in mid-2020. We expect
that the final efficacy analysis, if necessary, will be completed in early 2021. ThermoDox® has received U.S. FDA Fast Track Designation and has been
granted  orphan  drug  designation  for  primary  liver  cancer  in  both  the  U.S.  and  the  EU.  Additionally,  the  U.S.  FDA  has  provided  ThermoDox®  with  a
505(b)(2) registration pathway. Subject to a successful trial, the OPTIMA Study has been designed to support registration in all key primary liver cancer
markets. We fully expect to submit registrational applications in the U.S., Europe and China. We expect to submit, and we believe that applications will be
accepted in South Korea, Taiwan and Vietnam, three other significant markets for ThermoDox® if it were to receive approval in Europe, China or the U.S.

On December 18, 2018, we announced that the DMC for the OPTIMA Study completed its last scheduled review of all patients enrolled in the trial and
unanimously recommended that the OPTIMA Study continue according to protocol to its final data readout. The DMC’s recommendation was based on the
committee’s assessment of safety and data integrity of all patients randomized in the trial as of October 4, 2018. The DMC reviewed study data at regular
intervals throughout the patient enrollment period, with the primary responsibilities of ensuring the safety of all patients enrolled in the study, the quality of
the  data  collected,  and  the  continued  scientific  validity  of  the  study  design.  As  part  of  its  review  of  all  556  patients  enrolled  into  the  trial,  the  DMC
evaluated  a  quality  matrix  relating  to  the  total  clinical  data  set,  confirming  the  timely  collection  of  data,  that  all  data  are  current  as  well  as  other  data
collection and quality criteria.

On August 5, 2019, the Company announced that the prescribed number of OS events had been reached for the first prespecified interim analysis of the
OPTIMA Phase III Study. Following preparation of the data, the first interim analysis was conducted by the DMC on November 1, 2019. This timeline was
consistent  with  the  Company’s  stated  expectations  and  is  necessary  to  provide  a  full  and  comprehensive  data  set  that  may  represent  the  potential  for  a
successful trial outcome. In accordance with the statistical plan, this initial interim analysis has a target of 118 events, or 60% of the total number required
for  the  final  analysis.  At  the  time  of  the  data  cutoff,  the  Company  received  reports  of  128  events.  The  hazard  ratio  for  success  at  128  events  is
approximately 0.63, which represents a 37% reduction in the risk of death compared with RFA alone and is consistent with the 0.65 hazard ratio that was
observed in the prospective HEAT Study subgroup, which demonstrated a two-year overall survival advantage and a median time to death of more than
seven and a half years.

On August 13, 2019, the Company announced that results from an independent analysis of the Company’s ThermoDox® HEAT Study conducted by the
National Institutes of Health (NIH) were published in the peer-reviewed publication, Journal of Vascular and Interventional Radiology. The analysis was
conducted by the intramural research program of the NIH and the NIH Center for Interventional Oncology (CIO), with the full data set from the Company’s
HEAT Study. The analysis evaluated the full data set to determine if there was a correlation between baseline tumor volume and radiofrequency ablation
(RFA)  heating  time  (minutes/tumor  volume  in  milliliters),  with  or  without  ThermoDox®  treatment,  for  patients  with  HCC.  The  NIH  analysis  was
conducted under the direction of Dr. Bradford Wood, MD, Director, NIH Center for Interventional Oncology and Chief, NIH Clinical Center Interventional
Radiology.

The article titled, “RFA Duration Per Tumor Volume May Correlate With Overall Survival in Solitary Hepatocellular Carcinoma Patients Treated With RFA
Plus Lyso-thermosensitive Liposomal Doxorubicin,” discussed the NIH analysis of results from 437 patients in the HEAT Study (all patients with a single
lesion representing 62.4% of the study population). The key finding was that increased RFA heating time per tumor volume significantly improved overall
survival (OS) in patients with single-lesion HCC who were treated with RFA plus ThermoDox®, compared to patients treated with RFA alone. A one-unit
increase in RFA duration per tumor volume was shown to result in about a 20% improvement in OS for patients administered ThermoDox®, compared to
RFA  alone.  The  authors  conclude  that  increasing  RFA  heating  time  in  combination  with  ThermoDox®  significantly  improves  OS  and  establishes  an
improvement of over two years versus the control arm when the heating time per milliliter of tumor is greater than 2.5 minutes. This finding is consistent
with the Company’s own results, which defined the optimized RFA procedure as a 45-minute treatment for tumors with a diameter of 3 centimeters. Thus,
the NIH analysis lends support to the hypothesis underpinning the OPTIMA Study.

On August 27, 2019, the Company announced that a study from a single site in China titled “Thermosensitive liposomal doxorubicin plus radiofrequency
ablation increased tumor destruction and improved survival in patients with medium and large hepatocellular carcinoma: A randomized, double-blinded,
dummy-controlled clinical trial in a single center” has been published in the Journal of Cancer Research and Therapeutics. These data were generated as
part of the Phase III HEAT (Hepatocellular Carcinoma Study of RFA and ThermoDox®) Study sponsored by Celsion. The data from this single site at the
Peking University Cancer Hospital and Institute in Beijing show an OS improvement of 22.5 months in patients with 3-7 cm unresectable hepatocellular
carcinoma (HCC) tumors receiving combined radiofrequency ablation (RFA) and ThermoDox®, compared with the use of RFA alone.

In  this  study,  patients  received  50  mg/m2  of  ThermoDox®  or  placebo,  plus  RFA  for  45  minutes  or  longer.  Patients  were  followed  for  11  to  80  months
(average: 49.1 ± 24.8 months), with 18 of 22 patients completing the study. The mean OS for the ThermoDox® plus RFA group was 68.5 ± 7.2 months,
which was significantly greater than the placebo plus RFA group (46.0 ± 10.6 months, pValue = 0.045). At the end of the follow-up period, the percentage
of patients alive after 1, 3 and 5 years were as follows:

Yang W, Lee JC, Chen MH, Zhang ZY, Bai XM, Yin SS, et al. from the Departments of Ultrasound and Radiology, Key Laboratory of Carcinogenesis and
Translational  Research  (Ministry  of  Education),  Peking  University  Cancer  Hospital  and  Institute  in  Beijing.  Professor  Min-Hua  Chen  was  a  principal
investigator in Celsion’s Phase III HEAT Study, from which these data are derived, and is also a principal investigator in the Company’s ongoing Phase III
OPTIMA Study for the treatment of primary liver cancer with ThermoDox® plus standardized RFA.

On  November  4,  2019,  the  Company  announced  that  the  DMC  unanimously  recommended  the  OPTIMA  Study  continue  according  to  protocol.  The
recommendation  was  based  on  a  review  of  blinded  safety  and  data  integrity  from  556  patients  enrolled  in  the  Company’s  multinational,  double-blind,
placebo-controlled pivotal Phase III OPTIMA Study with ThermoDox®.

The DMC’s pre-planned interim efficacy review followed 128 patient events, or deaths, which occurred in August 2019. Data presented demonstrated that
PFS and OS data appear to be tracking with patient data observed at a similar time point in the Company’s subgroup of patients followed prospectively in
the earlier Phase III HEAT Study, upon which the OPTIMA Study is based.

The data review demonstrated the following:

● The OPTIMA Study patient demographics and risk factors are consistent with what the Company observed in the HEAT Study subgroup with all

data quality metrics meeting expectations.

● Median PFS for the OPTIMA Study reached 17 months as of August 2019. These blinded data compare favorably with 16 months median PFS for

all 285 patients in the HEAT Study subgroup of patients treated with RFA >45 minutes.

● Median OS for the OPTIMA Study has not been reached as of August 5, 2019, however median OS appears to be consistent with the HEAT Study

subgroup of patients treated with RFA >45 minutes and followed prospectively for overall survival.

● The OPTIMA Study has lost only 4 patients to follow-up from the initiation of the trial in September 2014 through August 2019 while the trial

design allows for 3% risk for loss per year, which at this point would have exceeded 60 patients.

While the Company has not unblinded the study to report a hazard ratio, PFS and OS are tracking similarly to the subgroup of patients who received more
than 45 minutes of RFA in our HEAT Study and followed prospectively for more than three years. This subgroup in the HEAT Study demonstrated a 2-year
overall survival advantage and a median time to death of more than 7 ½ years. This tracking appears to bode well for study success at the second of two
pre-planned interim efficacy analysis which is intended after a minimum of 158 patient deaths and is projected to occur during the second quarter of 2020.
The hazard ratio for success at 158 events is 0.70 with a P-value of 0.022 This is below the hazard ratio of 0.65, P-value = 0.02 observed for the HEAT
Study subgroup of patients treated with RFA > 45 minutes.

IMMUNO-ONCOLOGY Program

On June 20, 2014, we completed the acquisition of substantially all of the assets of EGEN, a private company located in Huntsville, Alabama. Pursuant to
the  Asset  Purchase  Agreement,  CLSN  Laboratories  acquired  all  of  EGEN’s  right,  title  and  interest  in  and  to  substantially  all  of  the  assets  of  EGEN,
including  cash  and  cash  equivalents,  patents,  trademarks  and  other  intellectual  property  rights,  clinical  data,  certain  contracts,  licenses  and  permits,
equipment,  furniture,  office  equipment,  furnishings,  supplies  and  other  tangible  personal  property.  A  key  asset  acquired  from  EGEN  was  the  TheraPlas
technology platform and the first drug candidate developed from it is GEN-1.

THERAPLAS Technology Platform

TheraPlas  is  a  technology  platform  for  the  delivery  of  DNA  and  mRNA  therapeutics  via  synthetic  non-viral  carriers  and  is  capable  of  providing  cell
transfection for double-stranded DNA plasmids and large therapeutic RNA segments such as mRNA. There are two components of the TheraPlas system, a
plasmid DNA or mRNA payload encoding a therapeutic protein, and a delivery system. The delivery system is designed to protect the DNA/RNA from
degradation  and  promote  trafficking  into  cells  and  through  intracellular  compartments.  We  designed  the  delivery  system  of  TheraPlas  by  chemically
modifying the low molecular weight polymer to improve its gene transfer activity without increasing toxicity. We believe that TheraPlas may be a viable
alternative  to  current  approaches  to  gene  delivery  due  to  several  distinguishing  characteristics,  including  enhanced  molecular  versatility  that  allows  for
complex modifications to potentially improve activity and safety.

The design of the TheraPlas delivery system is based on molecular functionalization of polyethyleneimine (PEI), a cationic delivery polymer with a distinct
ability  to  escape  from  the  endosomes  due  to  heavy  protonation.  The  transfection  activity  and  toxicity  of  PEI  is  tightly  coupled  to  its  molecular  weight
therefore the clinical application of PEI is limited. We have used molecular functionalization strategies to improve the activity of low molecular weight
PEIs  without  augmenting  their  cytotoxicity.  In  one  instance,  chemical  conjugation  of  a  low  molecular  weight  branched  BPEI1800  with  cholesterol  and
polyethylene glycol (PEG) to form PEG-PEI-Cholesterol (PPC) dramatically improved the transfection activity of BPEI1800 following in vivo delivery.
Together, the cholesterol and PEG modifications produced approximately 20-fold enhancement in transfection activity. Biodistribution studies following
intraperitoneal or subcutaneous administration of DNA/PPC nanocomplexes showed DNA delivery localized primarily at the injection site with only small
amount escaping into the systemic circulation. PPC is the delivery component of our lead TheraPlas product, GEN-1, which is in clinical development for
the treatment ovarian cancer and in preclinical development for the treatment of glioblastoma. The PPC manufacturing process has been scaled up from
bench scale (1-2 g) to 0.6Kg, and several current Good Manufacturing Practice, (“cGMP”) lots have been produced with reproducible quality.

We believe that TheraPlas has emerged as a viable alternative to current approaches due to several distinguishing characteristics such as strong molecular
versatility that may allow for complex modifications to potentially improve activity and safety with little difficulty. The biocompatibility of these polymers
reduces the risk of adverse immune response, thus allowing for repeated administration. Compared to naked DNA or cationic lipids, TheraPlas is generally
safer, more efficient, and cost effective. We believe that these advantages place Celsion in strong position to capitalize on this technology platform.

Ovarian Cancer Overview

Ovarian cancer is the most lethal of gynecological malignancies among women with an overall five-year survival rate of 45%. This poor outcome is due in
part to the lack of effective prevention and early detection strategies. There were approximately 22,000 new cases of ovarian cancer in the U.S. in 2014
with an estimated 14,000 deaths. Mortality rates for ovarian cancer declined very little in the last forty years due to the unavailability of detection tests and
improved  treatments.  Most  women  with  ovarian  cancer  are  not  diagnosed  until  Stages  III  or  IV,  when  the  disease  has  spread  outside  the  pelvis  to  the
abdomen  and  areas  beyond  causing  swelling  and  pain,  where  the  five-year  survival  rates  are  25  -  41  percent  and  11  percent,  respectively.  First-line
chemotherapy regimens are typically platinum-based combination therapies. Although this first line of treatment has an approximate 80 percent response
rate, 55 to 75 percent of women will develop recurrent ovarian cancer within two years and ultimately will not respond to platinum therapy. Patients whose
cancer recurs or progresses after initially responding to surgery and first-line chemotherapy have been divided into one of the two groups based on the time
from completion of platinum therapy to disease recurrence or progression. This time period is referred to as platinum-free interval. The platinum-sensitive
group  has  a  platinum-free  interval  of  longer  than  six  months.  This  group  generally  responds  to  additional  treatment  with  platinum-based  therapies.  The
platinum-resistant  group  has  a  platinum-free  interval  of  shorter  than  six  months  and  is  resistant  to  additional  platinum-based  treatments.  Pegylated
liposomal doxorubicin, topotecan, and Avastin are the only approved second-line therapies for platinum-resistant ovarian cancer. The overall response rate
for these therapies is 10 to 20 percent with median overall survival of eleven to twelve months. Immunotherapy is an attractive novel approach for the
treatment  of  ovarian  cancer  particularly  since  ovarian  cancers  are  considered  immunogenic  tumors.  IL-12  is  one  of  the  most  active  cytokines  for  the
induction  of  potent  anti-cancer  immunity  acting  through  the  induction  of  T-lymphocyte  and  natural  killer  cell  proliferation.  The  precedence  for  a
therapeutic role of IL-12 in ovarian cancer is based on epidemiologic and preclinical data.

GEN-1

GEN-1  is  a  DNA-based  immunotherapeutic  product  candidate  for  the  localized  treatment  of  ovarian  cancer  by  intraperitoneally  administering  an
Interleukin-12 (“IL-12”) plasmid formulated with our proprietary TheraPlas delivery system. In this DNA-based approach, the immunotherapy is combined
with a standard chemotherapy drug, which can potentially achieve better clinical outcomes than with chemotherapy alone. We believe that increases in IL-
12 concentrations at tumor sites for several days after a single administration could create a potent immune environment against tumor activity and that a
direct  killing  of  the  tumor  with  concomitant  use  of  cytotoxic  chemotherapy  could  result  in  a  more  robust  and  durable  antitumor  response  than
chemotherapy alone. We believe the rationale for local therapy with GEN-1 is based on the following.

● Loco-regional  production  of  the  potent  cytokine  IL-12  avoids  toxicities  and  poor  pharmacokinetics  associated  with  systemic  delivery  of

recombinant IL-12;

● Persistent local delivery of IL-12 lasts up to one week and dosing can be repeated; and

● Potential for long-term maintenance therapy.

OVATION I Study

In February 2015, we announced that the FDA accepted, without objection, the Phase Ib dose-escalation clinical trial of GEN-1 in combination with the
standard of care in neoadjuvant ovarian cancer (the “OVATION I Study”). On September 30, 2015, we announced enrollment of the first patient in the
OVATION I Study. The OVATION I Study was designed (i) to identify a safe, tolerable and potentially therapeutically active dose of GEN-1 by recruiting
and maximizing an immune response and (ii) to enroll three to six patients per dose level to evaluate safety and efficacy and attempt to define an optimal
dose for a follow-on Phase I/II study. In addition, the OVATION I Study establishes a unique opportunity to assess how cytokine-based compounds such as
GEN-1 directly affect ovarian cancer cells and the tumor microenvironment in newly diagnosed patients. The study was designed to characterize the nature
of the immune response triggered by GEN-1 at various levels of the patients’ immune system, including:

● Infiltration  of  cancer  fighting  T-cell  lymphocytes  into  primary  tumor  and  tumor  microenvironment  including  peritoneal  cavity,  which  is  the

primary site of metastasis of ovarian cancer;

● Changes in local and systemic levels of immuno-stimulatory and immunosuppressive cytokines associated with tumor suppression and growth,

respectively; and

● Expression profile of a comprehensive panel of immune related genes in pre-treatment and GEN-1-treated tumor tissue.

We initiated the OVATION I Study at four clinical sites at the University of Alabama at Birmingham, Oklahoma University Medical Center, Washington
University in St. Louis and the Medical College of Wisconsin. During 2016 and 2017, we announced data from the first fourteen patients in the OVATION
I Study who completed treatment. On October 3, 2017 we announced final clinical and translational research data from the OVATION Study.

GEN-1 plus standard chemotherapy produced positive clinical results, with no dose limiting toxicities and positive dose dependent efficacy signals which
correlate  well  with  positive  surgical  outcomes. The  OVATION  I  Study  evaluated  escalating  doses  of  GEN-1  (36  mg/m2,  47  mg/m2,  61  mg/m2  and  79
mg/m2) administered intraperitoneally in combination with three cycles of neoadjuvant chemotherapy prior to interval debulking surgery, followed by three
cycles of NAC in the treatment of newly diagnosed patients with Stage III/IV ovarian cancer.

In  this  Phase  IB  dose-escalation  study,  the  14  patients  who  were  evaluable  for  response  demonstrated  median  PFS  of  21  months  in  patients  treated  per
protocol and 17.1 months for the intent-to-treat population (n=18) for all dose cohorts, including three patients who dropped out of the study after 13 days
or less, and two patients who did not receive full NAC and GEN-1 cycles. In addition, 100% of patients administered NAC plus the two higher doses of
GEN-1 experienced an objective tumor response (defined as a partial or complete response) compared to only 60% of patients given the two lower doses.
Pathological  changes  were  assessed  as  part  of  the  study,  with  the  density  of  markers  measured  in  tissue  sections  assessed  via  immunohistochemistry
staining. Among patients administered the high doses of GEN-1 (n=8), pre-treatment to post-treatment reductions in key biomarkers were observed (FoxP3
-62.5%; IDO-1 -60%; PD-1 -62.5%; PD-L1 -37.5%). Reductions were also observed in patients administered the lower doses of GEN-1 (n=4) for all but
one of the four key biomarkers (FoxP3 -40%; IDO-1 -40%; PD-1 +25%; PD-L1 -37.5%). The ratio of CD8+ cells to the four key immunosuppressive cell
signals increased following treatment in 60 - 80% of patients.

Dose-limiting toxicity was not reached in the OVATION I Study.

OVATION 2 Study

On November 13, 2017, the Company filed its Phase I/II clinical trial protocol with the U.S. Food and Drug Administration for GEN-1 for the localized
treatment of ovarian cancer. The protocol is designed with a single dose escalation phase to 100 mg/m² to identify a safe and tolerable dose of GEN-1 while
maximizing an immune response. The Phase I portion of the study will be followed by a continuation at the selected dose in 130 patients randomized Phase
II study.

In  the  OVATION  2  Study,  patients  in  the  GEN-1  treatment  arm  will  receive  GEN-1  plus  chemotherapy  pre-  and  post-interval  debulking  surgery.  The
OVATION 2 Study will include up to 130 patients with Stage III/IV ovarian cancer, with 12 to 15 patients in the Phase I portion and up to 118 patients in
Phase  II.  The  study  is  80%  powered  to  show  a  33%  improvement  in  the  primary  endpoint,  PFS,  when  comparing  GEN-1  with  neoadjuvant  +  adjuvant
chemotherapy versus neoadjuvant + adjuvant chemotherapy alone. The PFS primary analysis will be conducted after at least 80 events have been observed
or after all patients have been followed for at least 16 months, whichever is later.

Developed  with  extensive  input  from  the  Company’s  Medical  Advisory  Board,  the  OVATION  2  Study  builds  on  promising  clinical  and  translational
research data from the Phase IB dose-escalation OVATION I Study, in which enrolled patients received escalating weekly doses of GEN-1 up to 79 mg/m²
for a total of eight treatments in combination with NACT, followed by IDS. In addition to exploring a higher dose of GEN-1 in the OVATION 2 study,
patients will continue to receive GEN-1 after their IDS in combination with adjuvant chemotherapy.

On November 5, 2019, the Company announced that the independent Data Safety Monitoring Board (DSMB) completed its safety review of data from the
first eight patients enrolled in the ongoing Phase I/II OVATION 2 Study. Based on the DSMB’s recommendation, the study will continue as planned and the
Company will proceed with completing enrollment in the Phase I portion of the trial.

The  latest  DSMB  review  of  GEN-1  at  100  mg/m²  (in  November  2019  and  February  2020)  has  confirmed  that  there  were  no  apparent  dose  limiting
toxicities detected in any of the patients dosed with GEN-1 and that intraperitoneal administration is well tolerated even when given with standard NACT.
Of the fifteen patients treated in the Phase I portion of the OVATION 2 Study, nine patients were treated with GEN-1 plus NACT and six patients were
treated with NACT only.

In March 2020, the Company announced highly encouraging initial clinical data from the first 15 patients enrolled in the ongoing Phase I/II OVATION 2
Study for patients newly diagnosed with Stage III and IV ovarian cancer. The OVATION 2 Study combines GEN-1, the Company’s IL-12 gene-mediated
immunotherapy, with standard-of-care neoadjuvant chemotherapy (NACT). Following NACT, patients undergo interval debulking surgery (IDS), followed
by three additional cycles of chemotherapy.

GEN-1  plus  standard  NACT  produced  positive  dose-dependent  efficacy  results,  with  no  dose-limiting  toxicities,  which  correlates  well  with  successful
surgical outcomes as summarized below: 

● Of the 15 patients treated in the Phase I portion of the OVATION 2 Study, nine patients were treated with GEN-1 at a dose of 100 mg/m² plus
NACT and six patients were treated with NACT only. All 15 patients had successful resections of their tumors, with seven out of nine patients
(78%)  in  the  GEN-1  treatment  arm  having  an  R0  resection,  which  indicates  a  microscopically  margin-negative  resection  in  which  no  gross  or
microscopic tumor remains in the tumor bed. Only three out of six patients (50%) in the NACT only treatment arm had a R0 resection.

● When combining these results with the surgical resection rates observed in the Company’s prior Phase Ib dose-escalation trial (the OVATION 1
Study), a population of patients with inclusion criteria identical to the OVATION 2 Study, the data reflect the strong dose-dependent efficacy of
adding GEN-1 to the current standard of care NACT:

0, 36, 47 mg/m² of GEN-1 plus NACT  n=12
61, 79, 100 mg/m² of GEN-1 plus NACT  n=17

% of Patients with 
R0 Resections

42%
82%

● The objective response rate (ORR) as measured by Response Evaluation Criteria in Solid Tumors (RECIST) criteria for the 0, 36, 47 mg/m² dose
GEN-1  patients  were  comparable,  as  expected,  to  the  higher  (61,  79,  100  mg/m²)  dose  GEN-1  patients,  with  both  groups  demonstrating  an
approximate 80% ORR.

Because of the risks and uncertainties discussed in this Annual Report, among others, we are unable to estimate the duration and completion costs of our
research and development projects or when, if ever, and to what extent we will receive cash inflows from the commercialization and sale of a product. In
addition, with the recent outbreak of the Covid-19 pandemic, we are still evaluating the impact that the pandemic will have on our trials and on our ability
to timely develop our product candidates. Our inability to complete any of our research and development activities, preclinical studies or clinical trials in a
timely  manner  or  our  failure  to  enter  into  collaborative  agreements  when  appropriate  could  significantly  increase  our  capital  requirements  and  could
adversely impact our liquidity. While our estimated future capital requirements are uncertain and could increase or decrease as a result of many factors,
including the extent to which we choose to advance our research, development activities, preclinical studies and clinical trials, or if we are in a position to
pursue manufacturing or commercialization activities, we will need significant additional capital to develop our product candidates through development
and clinical trials, obtain regulatory approvals and manufacture and commercialize approved products, if any. We do not know whether we will be able to
access  additional  capital  when  needed  or  on  terms  favorable  to  us  or  our  stockholders.  Our  inability  to  raise  additional  capital,  or  to  do  so  on  terms
reasonably acceptable to us, would jeopardize the future success of our business.

As a clinical stage biopharmaceutical company, our business and our ability to execute our strategy to achieve our corporate goals are subject to numerous
risks and uncertainties. Material risks and uncertainties relating to our business and our industry are described in “Part I, Item 1A. Risk Factors” in this
Annual Report.

BUSINESS STRATEGY AND DEVELOPMENT PLAN

We have not generated and do not expect to generate any revenue from product sales in the next several years, if at all. An element of our business strategy
has been to pursue, as resources permit, the research and development of a range of product candidates for a variety of indications. We may also evaluate
licensing cancer products from third parties for cancer treatments to expand our current product pipeline. This is intended to allow us to diversify the risks
associated with our research and development expenditures. To the extent we are unable to maintain a broad range of product candidates, our dependence
on the success of one or a few product candidates would increase and results such as those announced in relation to the HEAT study on January 31, 2013
will  have  a  more  significant  impact  on  our  financial  prospects,  financial  condition  and  market  value.  We  may  also  consider  and  evaluate  strategic
alternatives, including investment in, or acquisition of, complementary businesses, technologies or products. As demonstrated by the HEAT Study results,
drug research and development is an inherently uncertain process and there is a high risk of failure at every stage prior to approval. The timing and the
outcome  of  clinical  results  are  extremely  difficult  to  predict.  The  success  or  failure  of  any  preclinical  development  and  clinical  trial  can  have  a
disproportionately positive or negative impact on our results of operations, financial condition, prospects and market value.

Our  current  business  strategy  includes  the  possibility  of  entering  into  collaborative  arrangements  with  third  parties  to  complete  the  development  and
commercialization of our product candidates. In the event that third parties take over the clinical trial process for one or more of our product candidates, the
estimated  completion  date  would  largely  be  under  the  control  of  that  third  party  rather  than  us.  We  cannot  forecast  with  any  degree  of  certainty  which
proprietary  products  or  indications,  if  any,  will  be  subject  to  future  collaborative  arrangements,  in  whole  or  in  part,  and  how  such  arrangements  would
affect our development plan or capital requirements. We may also apply for subsidies, grants or government or agency-sponsored studies that could reduce
our development costs.

We had $16.7 million in cash, investments, interest receivable and deferred income tax asset as of December 31, 2019. During the first quarter of 2020, we
raised an additional $6.4 million in capital under the 2019 Aspire Purchase Agreement and from the February 2020 Registered Direct Offering (as defined
below). Given our development plans, we anticipate cash resources will be sufficient to fund our operations and financial commitments through mid-2021.
In addition, the Company has approximately $15 million available under the Capital on Demand Agreement with JonesTrading International Services LLC.
On  March  5,  2020,  we  announced  the  termination  of  the  2019  Aspire  Purchase  Agreement.  Other  than  the  Capital  on  Demand  Agreement  with  Jones
Trading that provides us the ability to sell equity securities in the future, we have no other committed sources of additional capital.

As a result of the risks and uncertainties discussed in this Annual Report, among others, we are unable to estimate the duration and completion costs of our
research and development projects or when, if ever, and to what extent we will receive cash inflows from the commercialization and sale of a product if one
of our product candidates receives regulatory approval for marketing, if at all. Our inability to complete any of our research and development activities,
preclinical studies or clinical trials in a timely manner or our failure to enter into collaborative agreements when appropriate could significantly increase
our  capital  requirements  and  could  adversely  impact  our  liquidity.  While  our  estimated  future  capital  requirements  are  uncertain  and  could  increase  or
decrease as a result of many factors, including the extent to which we choose to advance our research and development activities, preclinical studies and
clinical trials, or whether we are in a position to pursue manufacturing or commercialization activities, we will need significant additional capital to develop
our product candidates through development and clinical trials, obtain regulatory approvals and manufacture and commercialize approved products, if any.
We do not know whether we will be able to access additional capital when needed or on terms favorable to us or our stockholders. Our inability to raise
additional  capital,  or  to  do  so  on  terms  reasonably  acceptable  to  us,  would  jeopardize  the  future  success  of  our  business.  See  Item  7  -  Management’s
Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations  for  additional  information  regarding  the  Company’s  financial  condition,
liquidity and capital resources.

RESEARCH AND DEVELOPMENT EXPENDITURES

We are engaged in a limited amount of research and development in our own facilities and have sponsored research programs in partnership with various
research institutions, including the National Institutes of Health, the National Cancer Institute and Duke University. We are currently, with minimal cash
expenditures,  sponsoring  clinical  and  pre-clinical  research  at  the  University  of  Oxford,  University  of  Utrecht,  Oklahoma  State  University  and  the
Children’s Hospital Research Institute. The majority of the spending in research and development is for the funding of ThermoDox® and GEN-1 clinical
trials.  Research  and  development  expenses  were  approximately  $13.1  million  and  $11.9  million  for  the  years  ended  December  31,  2019  and  2018,
respectively. See Item 7 - Management’s Discussion and Analysis of Financial Condition and Results of Operations for additional information regarding
expenditures related to our research and development programs.

GOVERNMENT REGULATION

Government  authorities  in  the  U.S.,  at  the  federal,  state  and  local  level,  and  in  other  countries  extensively  regulate,  among  other  things,  the  research,
development,  testing,  quality  control,  approval,  manufacturing,  labeling,  post-approval  monitoring  and  reporting,  recordkeeping,  packaging,  promotion,
storage, advertising, distribution, marketing and export and import of pharmaceutical products such as those we are developing. The process of obtaining
regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of
substantial time and financial resources

Regulation in the United States

In the United States, the FDA regulates drugs and biological products under the Federal Food, Drug, and Cosmetic Act (FDCA), the Public Health Service
Act (PHSA) and implementing regulations. Failure to comply with the applicable FDA requirements at any time pre- or post-approval may result in a delay
of  approval  or  administrative  or  judicial  sanctions.  These  sanctions  could  include  the  FDA’s  imposition  of  a  clinical  hold  on  trials,  refusal  to  approve
pending  applications,  withdrawal  of  an  approval,  issuance  of  warning  or  untitled  letters,  product  recalls,  product  seizures,  total  or  partial  suspension  of
production or distribution, injunctions, fines, civil penalties or criminal prosecution.

Research and Development

The vehicle by which FDA approves a new pharmaceutical product for sale and marketing in the U.S. is a New Drug Application (“NDA”) or a Biologics
License Application (BLA). A new drug or biological product cannot be marketed in the United States without FDA’s approval of an NDA/BLA. The steps
ordinarily  required  before  a  new  drug  can  be  marketed  in  the  U.S.  include  (a)  completion  of  pre-clinical  and  clinical  studies;  (b)  submission  and  FDA
acceptance of an Investigational New Drug application (IND), which must become effective before human clinical trials may commence; (c) completion of
adequate  and  well-controlled  human  clinical  trials  to  establish  the  safety  and  efficacy  of  the  product  to  support  each  of  its  proposed  indications;  (d)
submission and FDA acceptance of an NDA/BLA; (e) completion of an FDA inspection and potential audits of the facilities where the drug or biological
product  is  manufactured  to  assess  compliance  with  the  current  good  manufacturing  practices  (cGMP)  and  to  assure  adequate  identity,  strength,  quality,
purity, and potency; and (e) FDA review and approval of the NDA/BLA.

Pre-clinical tests include laboratory evaluations of product chemistry, toxicity, formulation and stability, as well as animal studies, to assess the potential
safety and efficacy of the product. Pre-clinical safety tests must be conducted by laboratories that comply with FDA regulations regarding good laboratory
practice. The results of pre-clinical tests are submitted to the FDA as part of an IND and are reviewed by the FDA before the commencement of human
clinical trials. Submission of an IND will not necessarily result in FDA authorization to commence clinical trials, and the absence of FDA objection to an
IND does not necessarily mean that the FDA will ultimately approve an NDA/BLA or that a product candidate otherwise will come to market.

Clinical  trials  involve  the  administration  of  the  investigational  product  to  human  subjects  under  the  supervision  of  a  qualified  principal  investigator.
Clinical  trials  must  be  conducted  in  accordance  with  good  clinical  practices  under  protocols  submitted  to  the  FDA  as  part  of  an  IND  and  with  patient
informed consent. Also, each clinical trial must be approved by an Institutional Review Board (IRB), and is subject to ongoing IRB monitoring.

Clinical trials are typically conducted in three sequential phases, but the phases may overlap or be combined. Phase I clinical trials may be conducted in
patients or healthy volunteers to evaluate the product’s safety, dosage tolerance and pharmacokinetics and, if possible, seek to gain an early indication of its
effectiveness.  Phase  II  clinical  trials  usually  involve  controlled  trials  in  a  larger  but  still  relatively  small  number  of  subjects  from  the  relevant  patient
population to evaluate dosage tolerance and appropriate dosage; identify possible short-term adverse effects and safety risks; and provide a preliminary
evaluation of the efficacy of the drug for specific indications. Phase III clinical trials are typically conducted in a significantly larger patient population and
are intended to further evaluate safety and efficacy, establish the overall risk-benefit profile of the product, and provide an adequate basis for physician
labeling.

In  certain  circumstances,  a  therapeutic  product  candidate  being  studied  in  clinical  trials  may  be  made  available  for  treatment  of  individual  patients.
Pursuant to the 21st Century Cures Act (Cures Act), the manufacturer of an investigational product for a serious disease or condition is required to make
available, such as by posting on its website, its policy on evaluating and responding to requests for individual patient access to such investigational product.

There can be no assurance that any of our clinical trials will be completed successfully within any specified time period or at all. Either the FDA or we may
suspend  clinical  trials  at  any  time  on  various  grounds,  including  among  other  things,  if  we,  the  FDA,  our  independent  DMC,  or  the  IRB  conclude  that
clinical subjects are being exposed to an unacceptable health risk. The FDA inspects and reviews clinical trial sites, informed consent forms, data from the
clinical trial sites (including case report forms and record keeping procedures) and the performance of the protocols by clinical trial personnel to determine
compliance  with  good  clinical  practices.  The  conduct  of  clinical  trials  is  complex  and  difficult,  and  there  can  be  no  assurance  that  the  design  or  the
performance of the pivotal clinical trial protocols of any of our current or future product candidates will be successful.

The results of pre-clinical studies and clinical trials, if successful, are submitted to FDA in the form of an NDA or BLA. Among other things, the FDA
reviews an NDA to determine whether the product is safe and effective for its intended use and reviews a BLA to determine whether the product is safe,
pure, and potent, and in each case, whether the product candidate is being manufactured in accordance with cGMP. The testing, submission, and approval
process requires substantial time, effort, and financial resources, including substantial application user fees and annual product and establishment user fees.
There can be no assurance that any approval will be granted for any product at any time, according to any schedule, or at all. The FDA may refuse to accept
or approve an application if it determines that applicable regulatory criteria are not satisfied. The FDA may also require additional testing for safety and
efficacy.  Even,  if  regulatory  approval  is  granted,  the  approval  will  be  limited  to  specific  indications.  There  can  be  no  assurance  that  any  of  our  current
product candidates will receive regulatory approvals for marketing or, if approved, that approval will be for any or all of the indications that we request.

The  FDA  has  agreed  to  certain  performance  goals  in  the  review  of  NDAs  and  BLAs.  The  FDA  has  60  days  from  its  receipt  of  an  NDA  or  BLA  to
determine  whether  the  application  will  be  accepted  for  filing  based  on  the  agency’s  threshold  determination  that  it  is  sufficiently  complete  to  permit
substantive review. Once the NDA/BLA is accepted for filing, most standard reviews applications are completed within ten months of filing; most priority
review applications are reviewed within six months of filing. Priority review are applied to a product candidate that the FDA determines has the potential to
treat a serious or life-threatening condition and, if approved, would be a significant improvement in safety or effectiveness compared to available therapies.
The  review  process  for  both  standard  and  priority  review  may  be  extended  by  the  FDA  for  three  additional  months  to  consider  certain  late-submitted
information, or information intended to clarify information already provided in the submission.

Section 505(b)(2) NDAs

As an alternative path to FDA approval for modifications to formulations or uses of drugs previously approved by the FDA, an applicant may submit an
NDA under Section 505(b)(2) of the FDCA. Section 505(b)(2) was enacted as part of the Hatch-Waxman Amendments. A Section 505(b)(2) NDA is an
application that contains full reports of investigations of safety and effectiveness, but where at least some of the information required for approval comes
from studies not conducted by, or for, the applicant and for which the applicant has not obtained a right of reference or use from the person by or for whom
the investigations were conducted. This type of application permits reliance for such approvals on literature or on an FDA finding of safety, effectiveness or
both for an approved drug product.

As  such,  under  Section  505(b)(2),  the  FDA  may  rely,  for  approval  of  an  NDA,  on  data  not  developed  by  the  applicant.  The  FDA  may  also  require
companies to perform additional studies or measurements, including clinical trials, to support the change from the approved branded reference drug. The
FDA may then approve the new product candidate for the new indication sought by the 505(b)(2) applicant.

FDA Regulations Specific to Gene-Based Products

The Food and Drug Administration (FDA) regulates gene-based products as biological products. Biological products intended for therapeutic use may be
regulated  by  either  the  Center  for  Biologics  Evaluation  &  Research  (CBER)  or  the  Center  for  Biologics  Evaluation  &  Research  (CDER).  Gene-based
products  are  subject  to  extensive  regulation  under  the  FDCA,  the  PHSA,  and  their  implementing  regulations.  Each  clinical  trial  of  investigational  gene
therapies must be reviewed and approved by the Institutional Biosafety Committee (IBC) for each clinical site. IBCs were established under the National
Institutes of Health (NIH) Guidelines for Research Involving Recombinant or Synthetic Nucleic Acid Molecules to provide local review and oversight of
nearly all forms of research utilizing recombinant or synthetic nucleic acid molecules. The IBC assesses biosafety issues, specifically, safety practices and
containment procedures, related to the investigational product and clinical study. Compliance with the NIH Guidelines is mandatory for investigators at
institutions receiving NIH funds for research involving recombinant DNA, however many companies and other institutions not otherwise subject to the
NIH Guidelines voluntarily follow them. Such trials remain subject to FDA and other clinical trial regulations, and only after FDA, IBC, and other relevant
approvals are in place can these protocols proceed.

Additional Controls for Biological Products

To help reduce the increased risk of the introduction of adventitious agents, the PHSA emphasizes the importance of manufacturing controls for products
whose  attributes  cannot  be  precisely  defined.  The  PHSA  also  provides  authority  to  the  FDA  to  immediately  suspend  licenses  in  situations  where  there
exists a danger to public health, to prepare or procure products in the event of shortages and critical public health needs, and to authorize the creation and
enforcement of regulations to prevent the introduction or spread of communicable diseases in the United States and between states.

After a BLA is approved, the biological product may be subject to official lot release as a condition of approval. As part of the manufacturing process, the
manufacturer is required to perform certain tests on each lot of the product before it is released for distribution. If the product is subject to official release
by the FDA, the manufacturer submits samples of each lot of product to the FDA together with a release protocol showing a summary of the history of
manufacture of the lot and the results of all of the manufacturer’s tests performed on the lot. The FDA may also perform certain confirmatory tests on lots
of some products, such as viral vaccines, before releasing the lots for distribution by the manufacturer.

In addition, the FDA conducts laboratory research related to the regulatory standards on the safety, purity, potency, and effectiveness of biological products.
As  with  drugs,  after  approval  of  biological  products,  manufacturers  must  address  any  safety  issues  that  arise,  are  subject  to  recalls  or  a  halt  in
manufacturing, and are subject to periodic inspection after approval.

Expedited Development and Review Programs

The FDA has various programs, including Fast Track, priority review, accelerated approval and breakthrough therapy, which are intended to expedite or
simplify the process for reviewing product candidates, or provide for the approval of a product candidate on the basis of a surrogate endpoint. Even if a
product candidate qualifies for one or more of these programs, the FDA may later decide that the product candidate no longer meets the conditions for
qualification or that the time period for FDA review or approval will be lengthened. Generally, product candidates that are eligible for these programs are
those  for  serious  or  life-threatening  conditions,  those  with  the  potential  to  address  unmet  medical  needs  and  those  that  offer  meaningful  benefits  over
existing  treatments.  For  example,  Fast  Track  is  a  process  designed  to  facilitate  the  development  and  expedite  the  review  of  product  candidates  to  treat
serious or life-threatening diseases or conditions and fill unmet medical needs.

Although Fast Track and priority review do not affect the standards for approval, the FDA will attempt to facilitate early and frequent meetings with a
sponsor  of  a  Fast  Track  designated  product  candidate  and  expedite  review  of  the  application  for  a  product  candidate  designated  for  priority  review.
Accelerated approval provides for an earlier approval for a new product candidate that meets the following criteria: is intended to treat a serious or life-
threatening disease or condition, generally provides a meaningful advantage over available therapies and demonstrates an effect on a surrogate endpoint
that is reasonably likely to predict clinical benefit or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality (IMM) that
is reasonably likely to predict an effect on IMM or other clinical benefit. A surrogate endpoint is a laboratory measurement or physical sign used as an
indirect  or  substitute  measurement  representing  a  clinically  meaningful  outcome.  As  a  condition  of  approval,  the  FDA  may  require  that  a  sponsor  of  a
product candidate receiving accelerated approval perform post-marketing clinical trials to verify and describe the predicted effect on irreversible morbidity
or mortality or other clinical endpoint, and the product may be subject to accelerated withdrawal procedures.

12

 
 
 
 
 
 
 
 
 
 
 
 
 
 
A sponsor may seek FDA designation of a product candidate as a “breakthrough therapy” if the product candidate is intended, alone or in combination with
one  or  more  other  therapeutics,  to  treat  a  serious  or  life-threatening  disease  or  condition,  and  preliminary  clinical  evidence  indicates  that  the  product
candidate may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment
effects  observed  early  in  clinical  development.  A  request  for  Breakthrough  Therapy  designation  should  be  submitted  concurrently  with,  or  as  an
amendment to, an IND, but ideally no later than the end of Phase 2 meeting.

Disclosure of Clinical Trial Information

Sponsors  of  clinical  trials  of  FDA-regulated  products  are  required  to  register  and  disclose  certain  clinical  trial  information.  Information  related  to  the
product,  patient  population,  phase  of  investigation,  trial  sites  and  investigators,  and  other  aspects  of  the  clinical  trial  is  then  made  public  as  part  of  the
registration. Sponsors are also obligated to disclose the results of their clinical trials within one year of completion, although disclosure of the results of
these  trials  can  be  delayed  in  certain  circumstances  for  up  to  two  additional  years.  Competitors  may  use  this  publicly  available  information  to  gain
knowledge regarding the progress of development programs.

Orphan Drug Designation

In  2009,  the  FDA  granted  orphan  drug  designation  for  ThermoDox®  for  the  treatment  of  HCC.  In  2005,  the  FDA  granted  orphan  drug  designation  for
GEN-1 for the treatment of ovarian cancer. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review
and  approval  process.  However,  if  a  product  which  has  an  orphan  drug  designation  subsequently  receives  the  first  FDA  approval  for  the  indication  for
which it has such designation, the product is entitled to orphan drug exclusivity, which means the FDA may not approve any other application to market the
same drug for the same indication for a period of seven years, except in limited circumstances, such as a showing of clinical superiority to the product with
orphan exclusivity. Orphan drug designation can also provide opportunities for grant funding towards clinical trial costs, tax advantages and FDA user-fee
benefits.

Hatch-Waxman Exclusivity

The FDCA provides a five-year period of non-patent data exclusivity within the U.S. 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.  During  the
exclusivity period, the FDA generally may not accept for review an abbreviated new drug application (ANDA) or a 505(b)(2) NDA submitted by another
company that references the previously approved drug. However, an ANDA or 505(b)(2) NDA referencing the new chemical entity may be submitted after
four years if it contains a certification of patent invalidity or non-infringement.

Biosimilars

The Biologics Price Competition and Innovation Act of 2009 (BPCIA) created an abbreviated approval pathway for biological product candidates shown to
be  highly  similar  to  or  interchangeable  with  an  FDA  licensed  reference  product.  Biosimilarity  sufficient  to  reference  a  prior  FDA-approved  product
requires  that  there  be  no  differences  in  conditions  of  use,  route  of  administration,  dosage  form,  and  strength,  and  no  clinically  meaningful  differences
between the biological product candidate and the reference product in terms of safety, purity, and potency. Biosimilarity must be shown through analytical
trials,  animal  trials,  and  a  clinical  trial  or  trials,  unless  the  Secretary  of  Health  and  Human  Services  waives  a  required  element.  A  biosimilar  product
candidate may be deemed interchangeable with a prior approved product if it meets the higher hurdle of demonstrating that it can be expected to produce
the same clinical results as the reference product and, for products administered multiple times, the biological product and the reference product may be
switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference
product. To date, a handful of biosimilar products and no interchangeable products have been approved under the BPCIA. Complexities associated with the
larger, and often more complex, structures of biological products, as well as the process by which such products are manufactured, pose significant hurdles
to implementation, which is still being evaluated by the FDA.

13

 
 
 
 
 
 
 
 
 
 
 
A reference product is granted 12 years of exclusivity from the time of first licensure of the reference product, and no application for a biosimilar can be
submitted for four years from the date of licensure of the reference product. The first biological product candidate submitted under the abbreviated approval
pathway  that  is  determined  to  be  interchangeable  with  the  reference  product  has  exclusivity  against  a  finding  of  interchangeability  for  other  biological
products for the same condition of use for the lesser of (i) one year after first commercial marketing of the first interchangeable biosimilar, (ii) 18 months
after  the  first  interchangeable  biosimilar  is  approved  if  there  is  no  patent  challenge,  (iii)  18  months  after  resolution  of  a  lawsuit  over  the  patents  of  the
reference  product  in  favor  of  the  first  interchangeable  biosimilar  applicant,  or  (iv)  42  months  after  the  first  interchangeable  biosimilar’s  application  has
been approved if a patent lawsuit is ongoing within the 42-month period.

Post-Approval Requirements

After FDA approval of a product is obtained, we and our contract manufacturers are required to comply with various post-approval requirements, including
establishment registration and product listing, record-keeping requirements, reporting of adverse reactions and production problems to the FDA, providing
updated  safety  and  efficacy  information  for  drugs,  or  safety,  purity,  and  potency  for  biological  products,  and  complying  with  requirements  concerning
advertising and promotional labeling. As a condition of approval of an NDA/BLA, the FDA may require the applicant to conduct additional clinical trials
or other post market testing and surveillance to further monitor and assess the drug’s safety and efficacy. The FDA can also impose other post-marketing
controls on us as well as our products including, but not limited to, restrictions on sale and use, through the approval process, regulations and otherwise.
The  FDA  also  has  the  authority  to  require  the  recall  of  our  products  in  the  event  of  material  deficiencies  or  defects  in  manufacture. A  governmentally
mandated recall, or a voluntary recall by us, could result from a number of events or factors, including component failures, manufacturing errors, instability
of product or defects in labeling.

In addition, manufacturing establishments in the U.S. and abroad are subject to periodic inspections by the FDA and must comply with cGMP. To maintain
compliance with cGMP, manufacturers must expend funds, time and effort in the areas of production and quality control. The manufacturing process must
be capable of consistently producing quality batches of the product candidate and the manufacturer must develop methods for testing the quality, purity and
potency of the product candidate. 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 proposed shelf-life.

Foreign Clinical Studies to Support an IND, NDA, or BLA

The  FDA  will  accept  as  support  for  an  IND,  NDA,  or  BLA  a  well-designed,  well-conducted,  non-IND  foreign  clinical  trial  if  it  was  conducted  in
accordance with GCP and the FDA is able to validate the data from the trial through an on-site inspection, if necessary. A sponsor or applicant who wishes
to rely on a non-IND foreign clinical trial to support an IND must submit supporting information to the FDA to demonstrate that the trial conformed to
GCP. This information includes the investigator’s qualifications; a description of the research facilities; a detailed summary of the protocol and trial results
and, if requested, case records or additional background data; a description of the drug substance and drug product, including the components, formulation,
specifications, and, if available, the bioavailability of the product candidate; information showing that the trial is adequate and well controlled; the name
and address of the independent ethics committee that reviewed the trial and a statement that the independent ethics committee meets the required definition;
a summary of the independent ethics committee’s decision to approve or modify and approve the trial, or to provide a favorable opinion; a description of
how informed consent was obtained; a description of what incentives, if any, were provided to subjects to participate; a description of how the sponsor
monitored the trial and ensured that the trial was consistent with the protocol; a description of how investigators were trained to comply with GCP and to
conduct  the  trial  in  accordance  with  the  trial  protocol;  and  a  statement  on  whether  written  commitments  by  investigators  to  comply  with  GCP  and  the
protocol were obtained.

Regulatory  applications  based  solely  on  foreign  clinical  data  meeting  these  criteria  may  be  approved  if  the  foreign  data  are  applicable  to  the  U.S.
population and U.S. medical practice, the trials have been performed by clinical investigators of recognized competence, and the data may be considered
valid without the need for an on-site inspection by FDA or, if FDA considers such an inspection to be necessary, FDA is able to validate the data through
an on-site inspection or other appropriate means. Failure of an application to meet any of these criteria may result in the application not being approvable
based on the foreign data alone.

14

 
 
 
 
 
 
 
 
 
New Legislation and Regulations

From time to time, legislation is drafted, introduced and passed in Congress that could significantly change the statutory provisions governing the testing,
approval, manufacturing and marketing of products regulated by the FDA. In addition to new legislation, FDA regulations and policies are often revised or
interpreted by the agency in ways that may significantly affect our business and our products. It is impossible to predict whether further legislative changes
will  be  enacted  or  whether  FDA  regulations,  guidance,  policies  or  interpretations  will  be  changed  or  what  the  effect  of  such  changes,  if  any,  may  be.
Further, with the COVID-19 pandemic, it is possible that Congress and FDA may implement new laws, regulations, or policies that may impact our ability
to continue development programs as planned.

Other regulatory matters

Manufacturing,  sales,  promotion  and  other  activities  of  product  candidates  following  product  approval,  where  applicable,  or  commercialization  are  also
subject  to  regulation  by  numerous  regulatory  authorities  in  the  United  States  in  addition  to  the  FDA,  which  may  include  the  Centers  for  Medicare  &
Medicaid Services, or CMS, other divisions of the Department of Health and Human Services, or HHS, the Department of Justice, the Drug Enforcement
Administration,  the  Consumer  Product  Safety  Commission,  the  Federal  Trade  Commission,  the  Occupational  Safety  &  Health  Administration,  the
Environmental Protection Agency and state and local governments and governmental agencies.

Other healthcare laws

Healthcare providers, physicians, and third-party payors will play a primary role in the recommendation and prescription of any products for which we
obtain marketing approval. Our business operations and any current or future arrangements with third-party payors, healthcare providers and physicians
may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements
and relationships through which we develop, market, sell and distribute any drugs for which we obtain marketing approval. In the United States, these laws
include, without limitation, state and federal anti-kickback, false claims, physician transparency, and patient data privacy and security laws and regulations,
including but not limited to those described below.

● The federal Anti-Kickback Statute, which prohibits, among other things, persons and entities from knowingly and willfully soliciting, offering, paying,
receiving or providing any remuneration (including any kickback, bride, or certain rebate), 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, order  or  recommendation  of,  any  good  or  service,  for
which payment may be made, in whole or in part, under a federal healthcare program such as Medicare and Medicaid. A person or entity need not have
actual knowledge of the federal Anti-Kickback Statute or specific intent to violate it in order to have committed a violation. Violations are subject to
significant civil and criminal fines  and  penalties  for  each  violation,  plus  up  to  three  times  the  remuneration  involved,  imprisonment,  and  exclusion
from government healthcare programs. In addition, the government may assert that a claim that includes items or services resulting from a violation of
the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the civil False Claims Act.

● The federal civil and criminal false claims laws, including the civil False Claims Act, or FCA, which prohibit individuals or entities from, among other
things,  knowingly  presenting,  or  causing  to  be  presented,  to  the  federal  government,  claims  for  payment  or  approval  that  are  false,  fictitious  or
fraudulent; knowingly making, using, or causing to be made or used, a false statement or record material to a false or fraudulent claim or obligation to
pay  or  transmit  money  or  property  to  the  federal  government;  or  knowingly  concealing  or  knowingly  and  improperly  avoiding  or  decreasing  an
obligation to pay money to the federal government. Manufacturers can be held liable under the FCA even when they do not submit claims directly to
government payors if they are deemed to “cause” the submission of false or fraudulent claims. The FCA also permits a private individual acting as a
“whistleblower” to bring actions on behalf of the federal government alleging violations of the FCA and to share in any monetary recovery. When an
entity is determined to have violated the federal civil False Claims Act, the government may impose civil fines and penalties for each false claim, plus
treble damages, and exclude the entity from participation in Medicare, Medicaid and other federal healthcare programs.

● The federal civil monetary penalties laws, which impose civil fines for, among other things, the offering or transfer or remuneration to a Medicare or
state healthcare program beneficiary if the person knows or should know it is likely to influence the beneficiary’s selection of a particular provider,
practitioner, or supplier of services reimbursable by Medicare or a state health care program, unless an exception applies.

● The Health Insurance Portability and Accountability Act of 1996, or HIPAA, imposes criminal and civil liability for knowingly and willfully executing
a scheme, or attempting to execute a scheme, to defraud any healthcare benefit program, including private payors, knowingly and willfully embezzling
or  stealing  from  a  healthcare  benefit  program,  willfully  obstructing  a  criminal  investigation  of  a  healthcare  offense,  or  falsifying,  concealing  or
covering up a material fact or making any materially false statements 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, imposes, among other things, specified requirements on covered entities and their business associates relating to the privacy
and security of individually identifiable health information including mandatory contractual terms and required implementation of technical safeguards
of  such  information.  HITECH  also  created  new  tiers  of  civil  monetary  penalties,  amended  HIPAA  to  make  civil  and  criminal  penalties  directly
applicable to business associates in some cases, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal
courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions.

● The  Physician  Payments  Sunshine  Act,  enacted  as  part  of  the  Patient  Protection  and  Affordable  Care  Act,  as  amended  by  the  Health  Care  and
Education  Reconciliation  Act  of  2010,  or  collectively,  the  ACA,  imposed  new  annual  reporting  requirements  for  certain  manufacturers  of  drugs,
devices, biologics, and medical supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program, for
certain payments and “transfers of value” provided 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. In addition, many states also
require reporting of payments or other transfers of value, many of which differ from each other in significant ways, are often not pre-empted, and may
have  a  more  prohibitive  effect  than  the  Sunshine  Act,  thus  further  complicating  compliance  efforts.  Effective  January  1,  2022,  these  reporting
obligations will extend to include transfers of value made in the previous year to certain non-physician providers such as physician assistants and nurse
practitioners.

● Federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm consumers.
● Analogous  state  and  foreign  laws  and  regulations,  such  as  state  anti-kickback  and  false  claims  laws,  which  may  apply  to  sales  or  marketing
arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private  insurers,  and
may  be  broader  in  scope  than  their  federal  equivalents;  state  and  foreign  laws  that  require  pharmaceutical  companies  to  comply  with  the
pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government or otherwise
restrict  payments  that  may  be  made  to  healthcare  providers;  state  and  foreign  laws  that  require  drug  manufacturers  to  report  information  related  to
payments and other transfers of value to physicians and other healthcare providers and restrict marketing practices or require disclosure of marketing
expenditures and pricing information; and state and foreign laws that govern the privacy and security of health information in some circumstances.

 
 
 
 
 
 
 
 
These data privacy and security laws may differ from each other in significant ways and often are not pre-empted by HIPAA, which may complicate
compliance efforts.

15

 
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. It is possible that governmental authorities will conclude that our business practices do not comply with current or future statutes, regulations or
case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or
any other related governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages,
fines, imprisonment, disgorgement, exclusion from government funded healthcare programs, such as Medicare and Medicaid, reputational harm, additional
oversight and reporting obligations if we become subject to a corporate integrity agreement or similar settlement to resolve allegations of non-compliance
with  these  laws  and  the  curtailment  or  restructuring  of  our  operations.  If  any  of  the  physicians  or  other  healthcare  providers  or  entities  with  whom  we
expect  to  do  business  is  found  to  be  not  in  compliance  with  applicable  laws,  they  may  be  subject  to  similar  actions,  penalties  and  sanctions.  Ensuring
business arrangements comply with applicable healthcare laws, as well as responding to possible investigations by government authorities, can be time-
and resource-consuming and can divert a company’s attention from its business.

In  the  U.S.,  numerous  federal  and  state  laws  and  regulations,  including  state  data  breach  notification  laws,  state  health  information  privacy  laws,  and
federal  and  state  consumer  protection  laws,  govern  the  collection,  use,  disclosure,  and  protection  of  health-related  and  other  personal  information.  For
example, in June 2018, the State of California enacted the California Consumer Privacy Act of 2018 (the “CCPA”), which came into effect on January 1,
2020 and provides new data privacy rights for consumers and new operational requirements for companies, which may increase our compliance costs and
potential  liability.  The  CCPA  gives  California  residents  expanded  rights  to  access  and  delete  their  personal  information,  opt  out  of  certain  personal
information sharing, and receive detailed information about how their personal information is used. The CCPA provides for civil penalties for violations, as
well as a private right of action for data breaches that is expected to increase data breach litigation. While there is currently an exception for protected
health information that is subject to HIPAA and clinical trial regulations, as currently written, the CCPA may impact certain of our business activities. The
CCPA  could  mark  the  beginning  of  a  trend  toward  more  stringent  state  privacy  legislation  in  the  U.S.,  which  could  increase  our  potential  liability  and
adversely affect our business.

In  the  event  we  decide  to  conduct  clinical  trials  or  continue  to  enroll  subjects  in  our  ongoing  or  future  clinical  trials,  we  may  be  subject  to  additional
privacy restrictions. The collection, use, storage, disclosure, transfer, or other processing of personal data regarding individuals in the European Economic
Area,  or  EEA,  including  personal  health  data,  is  subject  to  the  EU  General  Data  Protection  Regulation,  or  GDPR,  which  became  effective  on  May  25,
2018. The GDPR is wide-ranging in scope and imposes numerous requirements on companies that process personal data, including requirements relating to
processing  health  and  other  sensitive  data,  obtaining  consent  of  the  individuals  to  whom  the  personal  data  relates,  providing  information  to  individuals
regarding  data  processing  activities,  implementing  safeguards  to  protect  the  security  and  confidentiality  of  personal  data,  providing  notification  of  data
breaches,  and  taking  certain  measures  when  engaging  third-party  processors.  The  GDPR  also  imposes  strict  rules  on  the  transfer  of  personal  data  to
countries  outside  the  EEA,  including  the  United  States,  and  permits  data  protection  authorities  to  impose  large  penalties  for  violations  of  the  GDPR,
including potential fines of up to €20 million or 4% of annual global revenues, whichever is greater. The GDPR also confers a private right of action on
data subjects and consumer associations to lodge complaints with supervisory authorities, seek judicial remedies, and obtain compensation for damages
resulting  from  violations  of  the  GDPR.  In  addition,  the  GDPR  includes  restrictions  on  cross-border  data  transfers.  The  GDPR  may  increase  our
responsibility and liability in relation to personal data that we process where such processing is subject to the GDPR, and we may be required to put in
place additional mechanisms to ensure compliance with the GDPR, including as implemented by individual countries. Compliance with the GDPR will be
a rigorous and time-intensive process that may increase our cost of doing business or require us to change our business practices, and despite those efforts,
there is a risk that we may be subject to fines and penalties, litigation, and reputational harm in connection with our European activities. Further, the United
Kingdom’s decision to leave the EU, often referred to as Brexit, has created uncertainty with regard to data protection regulation in the United Kingdom. In
particular, it is unclear how data transfers to and from the United Kingdom will be regulated now that the United Kingdom has left the EU.

Insurance Coverage and Reimbursement

In the United States and markets in other countries, patients who are prescribed treatments for their conditions and providers performing the prescribed
services generally rely on third-party payors to reimburse all or part of the associated healthcare costs. Thus, even if a product candidate is approved, sales
of the product will depend, in part, on the extent to which third-party payors, including government health programs in the United States such as Medicare
and Medicaid, commercial health insurers and managed care organizations, provide coverage, and establish adequate reimbursement levels for, the product.
In the United States, the principal decisions about reimbursement for new medicines are typically made by CMS, an agency within HHS. CMS decides
whether and to what extent a new medicine will be covered and reimbursed under Medicare and private payors tend to follow CMS to a substantial degree.
No  uniform  policy  of  coverage  and  reimbursement  for  drug  products  exists  among  third-party  payors.  Therefore,  coverage  and  reimbursement  for  drug
products can differ significantly from payor to payor. The process for determining whether a third-party payor will provide coverage for a product may be
separate from the process for setting the price or reimbursement rate that the payor will pay for the product once coverage is approved. Third-party payors
are increasingly challenging the prices charged, examining the medical necessity, and reviewing the cost-effectiveness of medical products and services and
imposing controls to manage costs. Third-party payors may limit coverage to specific products on an approved list, also known as a formulary, which might
not include all of the approved products for a particular indication.

In  order  to  secure  coverage  and  reimbursement  for  any  product  that  might  be  approved  for  sale,  a  company  may  need  to  conduct  expensive
pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of the product, in addition to the costs required to obtain
FDA  or  other  comparable  regulatory  approvals.  Additionally,  companies  may  also  need  to  provide  discounts  to  purchasers,  private  health  plans  or
government healthcare programs. Nonetheless, product candidates may not be considered medically necessary or cost effective. A decision by a third-party
payor not to cover a product could reduce physician utilization once the product is approved and have a material adverse effect on sales, our operations and
financial condition. Additionally, a third-party payor’s decision to provide coverage for a product does not imply that an adequate reimbursement rate will
be  approved.  Further,  one  payor’s  determination  to  provide  coverage  for  a  product  does  not  assure  that  other  payors  will  also  provide  coverage  and
reimbursement for the product, and the level of coverage and reimbursement can differ significantly from payor to payor.

The containment of healthcare costs has become a priority of federal, state and foreign governments, and the prices of products have been a focus in this
effort. Governments have shown significant interest in implementing cost-containment programs, including price controls, restrictions on reimbursement
and requirements for substitution of generic products. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies
in jurisdictions with existing controls and measures, could further limit a company’s revenue generated from the sale of any approved products. Coverage
policies and third-party payor reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or
more  products  for  which  a  company  or  its  collaborators  receive  regulatory  approval,  less  favorable  coverage  policies  and  reimbursement  rates  may  be
implemented in the future.

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

17

 
 
 
 
 
 
 
For a drug or biologic product to receive federal reimbursement under the Medicaid or Medicare Part B 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. As of 2010, the
Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively the ACA, expanded
the types of entities eligible to receive discounted 340B pricing, although under the current state of the law these newly eligible entities (with the exception
of children’s hospitals) will not be eligible to receive discounted 340B pricing on orphan drugs. As 340B drug pricing is determined based on AMP and
Medicaid rebate data, the revisions to the Medicaid rebate formula and AMP definition described above could cause the required 340B discount to increase.
Further, on December 27, 2018, the District Court for the District of Columbia invalidated a reimbursement formula change instituted by the Centers for
Medicare & Medicaid Services, or CMS, under the 340B program. For the 2019 and 2018 fiscal years, CMS altered the reimbursement formula. The court
ruled this change was not an “adjustment” that was within the Secretary’s discretion to make but was instead a fundamental change in the reimbursement
calculation,  and  such  a  dramatic  change  was  beyond  the  scope  of  the  Secretary’s  authority.  On  May  6,  2019,  the  district  court  reiterated  that  the  rate
reduction exceeded the Secretary’s authority and declared that the rate reduction for 2019 also exceeded the Secretary’s authority and remanded the issue to
HHS to devise an appropriate remedy. On July 10, 2019, the district court entered its final judgment and CMS has filed an appeal and a decision by the
Court of Appeals for the D.C. Circuit is pending. However, subsequently, hospitals have filed a complaint in the U.S. District Court for D.C. to enjoin the
reimbursement cuts for 2020. It is unclear how such litigation could affect covered hospitals who might purchase our products in the future and affect the
rates we may charge such facilities for our approved products. Changes to these current laws and state and federal healthcare reform measures that may be
adopted in the future may result in additional reductions in Medicare and other healthcare funding and otherwise affect the prices we may obtain for any
product candidates for which we may obtain regulatory approval or the frequency with which any such product candidate is prescribed or used.

These  laws,  and  future  state  and  federal  healthcare  reform  measures  may  be  adopted  in  the  future,  any  of  which  may  result  in  additional  reductions  in
Medicare  and  other  healthcare  funding  and  otherwise  affect  the  prices  we  may  obtain  for  any  product  candidates  for  which  we  may  obtain  regulatory
approval or the frequency with which any such product candidate is prescribed or used.

Outside the United States, ensuring coverage and adequate payment for a product also involves challenges, as the pricing of biological products is subject
to governmental control in many countries. For example, in the European Union, pricing and reimbursement schemes vary widely from country to country.
Some countries provide that products may be marketed only after a reimbursement price has been agreed. Some countries may require the completion of
additional studies that compare the cost effectiveness of a particular therapy to currently available therapies or so-called health technology assessments, in
order  to  obtain  reimbursement  or  pricing  approval.  Other  countries  may  allow  companies  to  fix  their  own  prices  for  products  but  monitor  and  control
product volumes and issue guidance to physicians to limit prescriptions. Efforts to control prices and utilization of biological products will likely continue
as countries attempt to manage healthcare expenditures.

Current and future healthcare reform legislation

In the United States and some foreign jurisdictions, there have been, and likely will continue to be, a number of legislative and regulatory changes and
proposed changes regarding the healthcare system directed at broadening the availability of healthcare, improving the quality of healthcare, and containing
or lowering the cost of healthcare. For example, in March 2010, the United States Congress enacted the Affordable Care Act, which, among other things,
includes  changes  to  the  coverage  and  payment  for  products  under  government  health  care  programs.  The  Affordable  Care  Act  includes  provisions  of
importance to our potential product candidates that:

● created  an  annual,  nondeductible  fee  on  any  entity  that  manufactures  or  imports  specified  branded  prescription  drugs  and  biologic  products,

apportioned among these entities according to their market share in certain government healthcare programs;

● expanded  eligibility  criteria  for  Medicaid  programs  by,  among  other  things,  allowing  states  to  offer  Medicaid  coverage  to  certain  individuals  with

income at or below 133% of the federal poverty level, thereby potentially increasing a manufacturer’s Medicaid rebate liability;

● expanded manufacturers’ rebate liability under the Medicaid Drug Rebate Program by increasing the minimum rebate for both branded and generic
drugs  and  revising  the  definition  of  “average  manufacturer  price,”  or  AMP,  for  calculating  and  reporting  Medicaid  drug  rebates  on  outpatient
prescription drug prices;

● addressed a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are

inhaled, infused, instilled, implanted or injected;

● expanded the types of entities eligible for the 340B drug discount program;
● established the Medicare Part D coverage gap discount program by requiring manufacturers to provide point-of-sale-discounts off the negotiated price
of applicable brand drugs to eligible beneficiaries during their coverage gap period as a condition for the manufacturers’ outpatient drugs to be covered
under Medicare Part D; and

● created a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research,

along with funding for such research.

Some  of  the  provisions  of  the  Affordable  Care  Act  have  yet  to  be  implemented,  and  there  have  been  judicial  and  Congressional  challenges  to  certain
provisions of the Affordable Care Act, as well as recent efforts by the Trump administration to repeal or replace certain aspects of the Affordable Care Act.
Since January 2017, President Trump has signed two Executive Orders and other directives designed to delay the implementation of certain provisions of
the Affordable Care Act. Concurrently, Congress has considered legislation that would repeal or repeal and replace all or part of the Affordable Care Act.
While Congress has not passed comprehensive repeal legislation, it has enacted laws that modify certain provisions of the Affordable Care Act such as
removing penalties, starting January 1, 2019, for not complying with the Affordable Care Act’s individual mandate to carry health insurance, delaying the
implementation of certain Affordable Care Act-mandated fees, and increasing the point-of-sale discount that is owed by pharmaceutical manufacturers who
participate in Medicare Part D. On December 14, 2018, a Texas U.S. District Court Judge ruled that the ACA is unconstitutional in its entirety because the
“individual  mandate”  was  repealed  by  Congress  as  part  of  the  Tax  Cuts  and  Jobs  Act  of  2017.  Additionally,  on  December  18,  2019,  the  U.S.  Court  of
Appeals for the 5th Circuit upheld the District Court ruling that the individual mandate was unconstitutional and remanded the case back to the District
Court  to  determine  whether  the  remaining  provisions  of  the  ACA  are  invalid  as  well.  On  March  2,  2020,  the  United  States  Supreme  Court  granted  the
petitions for writs of certiorari to review this case, and has allotted one hour for oral arguments, which are expected to occur in the fall. We will continue to
evaluate the effect that the ACA and its possible repeal and replacement has on our business.

Other legislative changes have been proposed and adopted in the United States since the Affordable Care Act was enacted. In August 2011, the Budget
Control Act of 2011, among other things, included aggregate reductions of Medicare payments to providers of 2% per fiscal year, which went into effect in
April 2013 and, due to subsequent legislative amendments to the statute, will remain in effect through 2029 unless additional Congressional action is taken.
In January 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several
providers, including hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations period for the government to recover
overpayments to providers from three to five years.

Moreover,  payment  methodologies  may  be  subject  to  changes  in  healthcare  legislation  and  regulatory  initiatives.  For  example,  CMS  may  develop  new
payment and delivery models, such as bundled payment models. In addition, recently there has been heightened governmental scrutiny over the manner in
which manufacturers set prices for their commercial products, which has resulted in several Congressional inquiries and proposed and enacted state and
federal legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer
patient programs, and reform government program reimbursement methodologies for pharmaceutical products. For example, at the federal level, the Trump
administration’s  budget  for  fiscal  year  2021  includes  a  $135  billion  allowance  to  support  legislative  proposals  seeking  to  reduce  drug  prices,  increase
competition, lower out-of-pocket drug costs for patients, and increase patient access to lower-cost generic and biosimilar drugs. Additionally, the Trump
administration previously released a “Blueprint” to lower drug prices and reduce out of pocket costs of drugs that contains additional proposals to increase
drug manufacturer competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of
their products, and reduce the out of pocket costs of drug products paid by consumers. HHS has solicited feedback on some of these measures and has
implemented others under its existing authority. For example, in May 2019, CMS issued a final rule to allow Medicare Advantage Plans the option of using
step therapy, a type of prior authorization, for Part B drugs beginning January 1, 2020. This final rule codified CMS’s policy change that was effective
January  1,  2019.  Although  a  number  of  these  and  other  measures  may  require  additional  authorization  to  become  effective,  Congress  and  the  Trump
administration  have  each  indicated  that  it  will  continue  to  seek  new  legislative  and/or  administrative  measures  to  control  drug  costs.  Any  reduction  in
reimbursement  from  Medicare  and  other  government  programs  may  result  in  a  similar  reduction  in  payments  from  private  payers.  At  the  state  level,
legislatures  are  increasingly  passing  legislation  and  implementing  regulations  designed  to  control  biopharmaceutical  and  biologic  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.

On  May  30,  2018,  the  Right  to  Try  Act  was  signed  into  law.  The  law,  among  other  things,  provides  a  federal  framework  for  certain  patients  to  access
certain  investigational  new  drug  products  that  have  completed  a  Phase  1  clinical  trial  and  that  are  undergoing  investigation  for  FDA  approval.  Under
certain  circumstances,  eligible  patients  can  seek  treatment  without  enrolling  in  clinical  trials  and  without  obtaining  FDA  permission  under  the  FDA
expanded access program. There is no obligation for a drug manufacturer to make its drug products available to eligible patients as a result of the Right to
Try Act, but the manufacturer must develop an internal policy and respond to patient requests according to that policy.

19

 
 
 
 
 
 
Regulation Outside of the U.S.

In addition to regulations in the U.S., we will be subject to a variety of regulations of other countries governing, among other things, any clinical trials and
commercial sales and distribution of our product candidates. Whether or not we obtain FDA approval (clinical trial or marketing) for a product, we must
obtain the requisite approvals from regulatory authorities in countries outside of the U.S., such as the EU and China, prior to the commencement of clinical
trials or marketing of the products in those countries. The approval process and requirements governing the conduct of clinical trials, product licensing,
pricing and reimbursement vary greatly from place to place, and the time may be longer or shorter than that required for FDA approval.

In the EU, before starting a clinical trial, a valid request for authorization must be submitted by the sponsor to the competent authority of the EU Member
State(s) in which the sponsor plans to conduct the clinical trial, as well as to an independent national Ethics Committee. A clinical trial may commence
only once the relevant Ethics Committee(s) has (have) issued a favorable opinion and the competent authority of the EU Member State(s) concerned has
(have) not informed the sponsor of any grounds for non-acceptance. Failure to comply with the EU requirements may subject a company to the rejection of
the request and the prohibition to start a clinical trial. Clinical trials conducted in the EU (or used for marketing authorization application in the EU) must
be  conducted  in  accordance  with  applicable  Good  Clinical  Practice  (“GCP”)  and  Good  Manufacturing  Practice  (“GMP”)  rules,  ICH  guidelines  and  be
consistent  with  ethical  principles.  EU  Member  State  inspections  are  regularly  conducted  to  verify  the  sponsor’s  compliance  with  applicable  rules.  The
sponsor is required to record and report to the relevant national competent authorities (and to the Ethics Committee) information about serious unexpected
suspected adverse reactions (“S.U.S.A.Rs”). The way clinical trials are conducted in the EU will undergo a major change when the new EU Clinical Trial
Regulation (Regulation 536/2014) comes into application in 2019.

As in the U.S., no medicinal product may be placed on the EU market unless a marketing authorization has been issued. In the EU, medicinal products may
be authorized either via the mutual recognition and decentralized procedure, the national procedure or the centralized procedure. The centralized procedure,
which is compulsory for medicines produced by biotechnology or those medicines intended to treat AIDS, cancer, neurodegenerative disorders or diabetes
and is optional for those medicines that are highly innovative, provides for the grant of a single marketing authorization that is valid for all EU Member
States.  Marketing  authorizations  granted  via  the  centralized  procedure  are  valid  for  all  EU  Member  States.  Products  submitted  for  approval  via  the
centralized procedure are assessed by the Committee for Medicinal Products for Human Use (CHMP), a committee within the European Medicine Agency
(EMA). The CHMP assesses, inter alia, whether a medicine meets the necessary quality, safety and efficacy requirements and whether it has a positive risk-
benefit balance. The requirements for an application dossier for a biological product contain different aspects than that of a chemical medicinal product.

In the EU, the requirements for pricing, coverage and reimbursement of any product candidates for which we obtain regulatory approval are provided for
by the national laws of EU Member States. Governments influence the price of pharmaceutical products through their pricing and reimbursement rules and
control of national health care systems that fund a large part of the cost of those products to consumers.

We  may  seek  orphan  designations  for  our  product  candidates.  In  the  EU,  as  we  understand  it,  a  medicinal  product  may  be  designated  as  an  orphan
medicinal product if the sponsor can establish that it is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating
condition affecting not more than five in 10 thousand persons, or that, for the same purposes, it is unlikely that the marketing of the medicinal product
would generate sufficient return; and that there exists no satisfactory method of diagnosis, prevention or treatment of the condition in question that has been
authorized in the EU or, if such method exists, that the medicinal product will be of significant benefit to those affected by that condition. Sponsors who
obtain orphan designation benefit from a type of scientific advice specific for designated orphan medicinal products and protocol assistance from the EMA.
Fee  reductions  are  also  available  depending  on  the  status  of  the  sponsor  and  the  type  of  service  required.  Marketing  authorization  applications  for
designated orphan medicinal products must be submitted through the centralized procedure.

20

 
 
 
 
 
 
 
 
The EU Data Protection Directive and Member State implementing legislation may also apply to health-related and other personal information obtained
outside  of  the  U.S.  The  Directive  will  be  replaced  by  the  EU  General  Data  Protection  Regulation  in  May  2018.  The  Regulation  will  increase  our
responsibility and liability in relation to personal data that we process, and we may be required to put in place additional mechanisms to ensure compliance
with the new EU data protection rules.

MANUFACTURING AND SUPPLY

We  do  not  currently  own  or  operate  manufacturing  facilities  for  the  production  of  preclinical,  clinical  or  commercial  quantities  of  any  of  our  product
candidates.  We  currently  contract  with  third  party  contract  manufacturing  organizations  (CMOs)  for  our  preclinical  and  clinical  trial  supplies,  and  we
expect to continue to do so to meet the preclinical and any clinical requirements of our product candidates. We have agreements for the supply of such drug
materials with manufacturers or suppliers that we believe have sufficient capacity to meet our demands. In addition, we believe that adequate alternative
sources  for  such  supplies  exist.  However,  there  is  a  risk  that,  if  supplies  are  interrupted,  it  would  materially  harm  our  business.  We  typically  order  raw
materials and services on a purchase order basis and do not enter into long-term dedicated capacity or minimum supply arrangements.

Manufacturing  is  subject  to  extensive  regulations  that  impose  various  procedural  and  documentation  requirements,  which  govern  record  keeping,
manufacturing  processes  and  controls,  personnel,  quality  control  and  quality  assurance,  among  others.  Our  CMOs  manufacture  our  product  candidates
under cGMP conditions. cGMP is a regulatory standard for the production of pharmaceuticals that will be used in humans which is recognized by FDA and
many foreign regulatory authorities.

SALES AND MARKETING

Our current focus is on the development of our existing portfolio, the completion of clinical trials and, if and where appropriate, the registration of our
product candidates. We currently do not have marketing, sales and distribution capabilities. If we receive marketing and commercialization approval for
any of our product candidates, we intend to market the product either directly or through strategic alliances and distribution agreements with third parties.
The ultimate implementation of our strategy for realizing the financial value of our product candidates is dependent on the results of clinical trials for our
product candidates, the availability of regulatory approvals and the ability to negotiate acceptable commercial terms with third parties.

PRODUCT LIABILITY AND INSURANCE

Our business exposes us to potential product liability risks that are inherent in the testing, manufacturing and marketing of human therapeutic products. We
presently have product liability insurance limited to $10 million per incident, and if we were to be subject to a claim in excess of this coverage or to a claim
not covered by our insurance and the claim succeeded, we would be required to pay the claim out of our own limited resources.

COMPETITION

Competition  in  the  discovery  and  development  of  new  methods  for  treating  and  preventing  disease  is  intense.  We  face,  and  will  continue  to  face,
competition from pharmaceutical and biotechnology companies, as well as academic and research institutions and government agencies both in the U.S.
and abroad. We face significant competition from organizations pursuing the same or similar technologies used by us in our drug discovery efforts and from
organizations developing pharmaceuticals that are competitive with our product candidates.

Most of our competitors, either alone or together with their collaborative partners, have substantially greater financial resources and larger research and
development  staffs  than  we  do.  In  addition,  most  of  these  organizations,  either  alone  or  together  with  their  collaborators,  have  significantly  greater
experience than we do in developing products, undertaking preclinical testing and clinical trials, obtaining FDA and other regulatory approvals of products,
and manufacturing and marketing products. Mergers and acquisitions in the pharmaceutical industry may result in even more resources being concentrated
among our competitors. These companies, as well as academic institutions, governmental agencies, and private research organizations, also compete with
us  in  recruiting  and  retaining  highly  qualified  scientific  personnel  and  consultants.  Our  ability  to  compete  successfully  with  other  companies  in  the
pharmaceutical and biotechnology field also depends on the status of our collaborations and on the continuing availability of capital to us.

ThermoDox®

Although  there  are  many  drugs  and  devices  marketed  and  under  development  for  the  treatment  of  cancer,  the  Company  is  not  aware  of  any  other  heat
activated  drug  delivery  product  either  being  marketed  or  in  human  clinical  development.  In  addition,  the  Company  is  not  aware  of  any  other  Phase  III
clinical trial for the treatment of newly diagnosed or intermediate stage HCC or primary liver cancer.

GEN-1

Studied indications for GEN-1 include ovarian cancer and glioblastoma multiforme (GBM) brain cancer. In evaluating the competitive landscape for both
indications, early stage indications are treated with chemotherapy (temozolomide, BCNU, CCNU for brain cancer; docetaxel, doxil and cisplatinum for
ovarian cancer), while later stage ovarian cancer is treated with Bevacizumab - Avastin®, an anti-angiogenesis inhibitor. Avastin® is currently also being
evaluated for early stage disease.

In product positioning for the ovarian cancer indications, there currently is no direct immunotherapy competitor for GEN-1, which will be studied as an
adjuvant  to  both  chemotherapy  standard  of  care  regimens,  as  well  as  anti-angiogenesis  compounds.  To  support  these  cases,  we  have  conducted  clinical
studies in combination with chemotherapy for ovarian cancer, and preclinical studies in combination with both temozolomide and Bevacizumab-Avastin®.

INTELLECTUAL PROPERTY

Licenses

Duke University License Agreement

In  1999,  we  entered  into  a  license  agreement  with  Duke  University  under  which  we  received  exclusive  rights,  subject  to  certain  exceptions,  to
commercialize  and  use  Duke’s  thermo-liposome  technology.  In  relation  to  these  liposome  patents  licensed  from  Duke  University,  we  have  filed  two
additional  patents  related  to  the  formulation  and  use  of  liposomes.  We  have  also  licensed  from  Valentis,  CA  certain  global  rights  covering  the  use  of
pegylation for temperature sensitive liposomes.

In  2003,  our  obligations  under  the  license  agreement  with  Duke  University  with  respect  to  the  testing  and  regulatory  milestones  and  other  licensed
technology  performance  deadlines  were  eliminated  in  exchange  for  a  payment  of  shares  of  our  common  stock.  The  license  agreement  continues  to  be
subject to agreements to pay a royalty based upon future sales. In conjunction with the patent holder, we have filed international applications for a certain
number of the U.S. patents.

Our rights under the license agreement with Duke University extend for the longer of 20 years or the end of any term for which any relevant patents are
issued by the United States Patent and Trademark Office. Currently we have rights to Duke’s patent for its thermo-liposome technology in the U.S. and to
future patents received by Duke in Canada, the EU, Japan and Australia, where it has patent applications have been granted. The European grant provides
coverage  in  the  European  Community.  For  this  technology,  our  license  rights  are  worldwide,  including  the  U.S.,  Canada,  certain  EU  Member  States,
Australia, Hong Kong, and Japan.

Patents and Proprietary Rights

Celsion  holds  an  exclusive  license  agreement  with  Duke  University  for  its  temperature-sensitive  liposome  technology  that  covers  the  ThermoDox®
formulation. Celsion also has issued patents which pertain specifically to methods of storing stabilized, temperature-sensitive liposomal formulations and
will assist in the protection of global rights. These patents will extend the overall term of the ThermoDox® patent portfolio to 2026. These patents are the
first  in  this  family,  which  includes  pending  applications  in  the  U.S.,  Europe  and  additional  key  commercial  geographies  in  Asia.  This  extended  patent
runway to 2026 allows for the evaluation of future development activities for ThermoDox® and Celsion’s heat-sensitive liposome technology platform.

For the ThermoDox® technology, we either exclusively license or own U.S. and international patents with claims and methods and compositions of matters
that cover various aspects of lysolipid thermally sensitive liposomes technology, with expiration dates ranging from 2018 to 2026.

For the TheraPlas technology, we own three U.S. and international patents and related applications with claims and methods and compositions of matters
that cover various aspects of TheraPlas and GEN-1 technologies, with expiration dates ranging from 2020 to 2028.

There can be no assurance that an issued patent will remain valid and enforceable in a court of law through the entire patent term. Should the validity of a
patent be challenged, the legal process associated with defending the patent can be costly and time consuming. Issued patents can be subject to oppositions,
interferences and other third-party challenges that can result in the revocation of the patent or maintenance of the patent in amended form (and potentially
in a form that renders the patent without commercially relevant or broad coverage). Competitors may be able to circumvent our patents. Development and
commercialization  of  pharmaceutical  products  can  be  subject  to  substantial  delays  and  it  is  possible  that  at  the  time  of  commercialization  any  patent
covering the product has expired or will be in force for only a short period of time following commercialization. We cannot predict with any certainty if
any  third-party  U.S.  or  foreign  patent  rights,  other  proprietary  rights,  will  be  deemed  infringed  by  the  use  of  our  technology.  Nor  can  we  predict  with
certainty which, if any, of these rights will or may be asserted against us by third parties. Should we need to defend ourselves and our partners against any
such claims, substantial costs may be incurred. Furthermore, parties making such claims may be able to obtain injunctive or other equitable relief, which
could  effectively  block  our  ability  to  develop  or  commercialize  some  or  all  of  our  products  in  the  U.S.  and  abroad  and  could  result  in  the  award  of
substantial damages. In the event of a claim of infringement, we or our partners may be required to obtain one or more licenses from a third party. There
can be no assurance that we can obtain a license on a reasonable basis should we deem it necessary to obtain rights to an alternative technology that meets
our needs. The failure to obtain a license may have a material adverse effect on our business, results of operations and financial condition.

In  addition  to  the  rights  available  to  us  under  completed  or  pending  license  agreements,  we  rely  on  our  proprietary  know-how  and  experience  in  the
development  and  use  of  heat  for  medical  therapies,  which  we  seek  to  protect,  in  part,  through  proprietary  information  agreements  with  employees,
consultants and others. There can be no assurance that these proprietary information agreements will not be breached, that we will have adequate remedies
for any breach, or that these agreements, even if fully enforced, will be adequate to prevent third-party use of the Company’s proprietary technology. Please
refer to “Item 1A, Risk Factors,” including, but not limited to, “We rely on trade secret protection and other unpatented proprietary rights for important
proprietary technologies, and any loss of such rights could harm our business, results of operations and financial condition.” Similarly, we cannot guarantee
that technology rights licensed to us by others will not be successfully challenged or circumvented by third parties, or that the rights granted will provide us
with adequate protection. Please refer to “Item 1A, Risk Factors,” including, but not limited to, “Our business depends on licensing agreements with third
parties to permit us to use patented technologies. The loss of any of our rights under these agreements could impair our ability to develop and market our
products.”

RECENT EVENTS

On  February  27,  2020,  the  Company  entered  into  a  Securities  Purchase  Agreement  (the  “Purchase  Agreement”)  with  several  institutional  investors,
pursuant to which the Company agreed to issue and sell, in a registered direct offering (the “Offering”), an aggregate of 4,571,428 shares (the “Shares”) of
our common stock at an offering price of $1.05 per share for gross proceeds of approximately $4.8 million before the deduction of the Placement Agent
fees and offering expenses. The Shares are being offered by the Company pursuant to a registration statement on Form S-3 (File No. 333-227236). The
Purchase Agreement contains customary representations, warranties and agreements by the Company and customary conditions to closing. The closing of
the Offering and the Private Placement occurred on March 3, 2020. In a concurrent private placement (the “Private Placement”), the Company agreed to
issue to the investors that participated in the Offering, for no additional consideration, warrants, to purchase up to 2,971,428 shares of Common Stock (the
“Original Warrants”). The Original Warrants were initially exercisable six months following their and were set to expire on the five-year anniversary of
such  initial  exercise  date.  The  Warrants  had  an  exercise  price  of  $1.15  per  share  subject  to  adjustment  as  provided  therein.  On  March  12,  2020  the
Company entered into private exchange agreements (the “Exchange Agreements”) with holders the Warrants. Pursuant to the Exchange Agreements, in
return for a higher exercise price of $1.24 per share of Common Stock, the Company issued new warrants to the Investors to purchase up to 3,200,000
shares  of  Common  Stock  (the  “Exchange  Warrants”)  in  exchange  for  the  Original  Warrants.  The  Exchange  Warrants,  like  the  Original  Warrants,  are
initially exercisable six months following their issuance (the “Initial Exercise Date”) and expire on the five-year anniversary of their Initial Exercise Date.
Other than having a higher exercise price, different issue date, Initial Exercise Date and expiration date, the terms of the Exchange Warrants are identical to
those of the Original Warrants.

On March 5, 2020, the Company delivered notice to Aspire Capital Fund, LLC, an Illinois limited liability company (“Aspire Capital”), terminating the
Common Stock Purchase Agreement dated October 28, 2019 (the “2019 Aspire Purchase Agreement”) with Aspire Capital effective as of March 6, 2020.
The  2019  Aspire  Purchase  Agreement  provided  that,  upon  the  terms  and  subject  to  the  conditions  and  limitations  set  forth  therein,  Aspire  Capital  was
committed to purchase up to an aggregate of $10 million of shares of the Company’s common stock over the 24-month term of the 2019 Aspire Purchase
Agreement at a price equal to (i) the lowest sale price of the Company’s common stock on the purchase date; or (ii) the arithmetic average of the three (3)
lowest closing sale prices for the Company’s common stock during the ten (10) consecutive trading days ending on the trading day immediately preceding
the purchase date. In consideration for entering into the 2019 Aspire Purchase Agreement, the Company issued to Aspire Capital 100,000 shares of the
Company’s common stock.

ITEM 1A. RISK FACTORS

We are providing the following cautionary discussion of risk factors, uncertainties and assumptions that we believe are relevant to our business. These are
factors  that,  individually  or  in  the  aggregate,  we  think  could  cause  our  actual  results  to  differ  materially  from  expected  or  historical  results  and  our
forward-looking  statements.  We  note  these  factors  for  investors  as  permitted  by  Section  21E  of  the  Securities  Exchange  Act,  and  Section  27A  of  the
Securities Act. You should understand that it is not possible to predict or identify all such factors. Consequently, you should not consider the following to be
a complete discussion of all potential risks or uncertainties that may impact our business. Moreover, we operate in a competitive and rapidly changing
environment. New factors emerge from time to time and it is not possible to predict the impact of all of these factors on our business, financial condition or
results of operations. We undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events, or
otherwise.

RISKS RELATED TO OUR BUSINESS

We have a history of significant losses from operations and expect to continue to incur significant losses for the foreseeable future.

Since our inception, our expenses have substantially exceeded our revenue, resulting in continuing losses and an accumulated deficit of $291 million at
December  31,  2019.  For  the  years  ended  December  31,  2019  and  2018,  we  incurred  net  losses  of  $16.9  million,  and  $11.9  million,  respectively.  We
currently have no product revenue and do not expect to generate any product revenue for the foreseeable future. Because we are committed to continuing
our product research, development, clinical trial and commercialization programs, we will continue to incur significant operating losses unless and until we
complete the development of ThermoDox®, GEN-1 and other new product candidates and these product candidates have been clinically tested, approved
by  the  United  States  Food  and  Drug  Administration  (FDA)  and  successfully  marketed.  The  amount  of  future  losses  is  uncertain.  Our  ability  to  achieve
profitability, if ever, will depend on, among other things, us or our collaborators successfully developing product candidates, obtaining regulatory approvals
to  market  and  commercialize  product  candidates,  manufacturing  any  approved  products  on  commercially  reasonable  terms,  establishing  a  sales  and
marketing organization or suitable third-party alternatives for any approved product and raising sufficient funds to finance business activities. If we or our
collaborators are unable to develop and commercialize one or more of our product candidates or if sales revenue from any product candidate that receives
approval  is  insufficient,  we  will  not  achieve  profitability,  which  could  have  a  material  adverse  effect  on  our  business,  financial  condition,  results  of
operations and prospects.

24

 
 
 
 
 
 
 
 
 
 
We do not expect to generate revenue for the foreseeable future.

We have devoted our resources to developing a new generation of products and will not be able to market these products until we have completed clinical
trials  and  obtain  all  necessary  governmental  approvals.  Our  lead  product  candidate,  ThermoDox®  and  the  product  candidates  we  purchased  in  our
acquisition  of  EGEN,  including  GEN-1,  are  still  in  various  stages  of  development  and  trials  and  cannot  be  marketed  until  we  have  completed  clinical
testing and obtained necessary governmental approval. Following our announcement on January 31, 2013 that the HEAT Study failed to meet its primary
endpoint of progression free survival, we continued to follow the patients enrolled in the HEAT Study to the secondary endpoint, overall survival. Based on
the overall survival data from the post-hoc analysis of results from the HEAT Study, we launched a pivotal, double-blind, placebo-controlled Phase III trial
of ThermoDox® in combination with RFA in primary liver cancer, known as the OPTIMA Study, in the first half of 2014. GEN-1 is currently in an early
stage of clinical development for the treatment of ovarian cancer. We conducted a Phase I dose-escalation clinical trial of GEN-1 in combination with the
standard  of  care  in  neo-adjuvant  ovarian  cancer  starting  in  the  second  half  of  2015  and  completing  enrollment  in  2017.  We  also  expanded  our  ovarian
cancer development program to include a Phase I/II dose escalating trial evaluating GEN-1 in ovarian cancer patients. Our delivery technology platforms,
TheraPlas and TheraSilence, are in preclinical stages of development. Accordingly, our revenue sources are, and will remain, extremely limited until our
product candidates are clinically tested, approved by the FDA or foreign regulatory agencies and successfully marketed. We cannot guarantee that any of
our product candidates will be approved by the FDA or any foreign regulatory agency or marketed, successfully or otherwise, at any time in the foreseeable
future or at all.

Drug development is an inherently uncertain process with a high risk of failure at every stage of development. Our lead drug candidate failed to
meet its primary endpoint in our earlier Phase III clinical trial.

On January 31, 2013, we announced that our lead product ThermoDox® in combination with radiofrequency ablation (RFA) failed to meet the primary
endpoint of the Phase III clinical trial for primary liver cancer, known as the HEAT study. We have not completed our final analysis of the data and do not
know the extent to which, if any, the failure of ThermoDox® to meet its primary endpoint in the Phase III trial could impact our other ongoing studies of
ThermoDox®  including  a  pivotal,  double-blind,  placebo-controlled  Phase  III  trial  of  ThermoDox®  in  combination  with  RFA  in  primary  liver  cancer,
known as the OPTIMA study, which we launched in the first half of 2014. The trial design of the OPTIMA study is based on the overall survival data from
the post-hoc analysis of results from the HEAT study. In addition, we have initiated a Phase I dose-escalation clinical trial of GEN-1 in combination with
the standard of care in neo-adjuvant ovarian cancer, known as the OVATION Study, and plan to expand our ovarian cancer development program to include
a Phase I/II dose escalating trial evaluating GEN-1, known as the OVATION II Study, in ovarian cancer patients.

Preclinical  testing  and  clinical  trials  are  long,  expensive  and  highly  uncertain  processes  and  failure  can  unexpectedly  occur  at  any  stage  of  clinical
development,  as  evidenced  by  the  failure  of  ThermoDox®  to  meet  its  primary  endpoint  in  the  HEAT  study.  Drug  development  is  inherently  risky  and
clinical  trials  take  us  several  years  to  complete.  The  start  or  end  of  a  clinical  trial  is  often  delayed  or  halted  due  to  changing  regulatory  requirements,
manufacturing challenges, required clinical trial administrative actions, slower than anticipated patient enrollment, changing standards of care, availability
or prevalence of use of a comparator drug or required prior therapy, clinical outcomes including insufficient efficacy, safety concerns, or our own financial
constraints. The results from preclinical testing or early clinical trials of a product candidate may not predict the results that will be obtained in later phase
clinical trials of the product candidate. We, the FDA or other applicable regulatory authorities may suspend clinical trials of a product candidate at any time
for various reasons, including a belief that subjects participating in such trials are being exposed to unacceptable health risks or adverse side effects. We
may not have the financial resources to continue development of, or to enter into collaborations for, a product candidate if we experience any problems or
other unforeseen events that delay or prevent regulatory approval of, or our ability to commercialize, product candidates. The failure of one or more of our
drug candidates or development programs could have a material adverse effect on our business, financial condition and results of operations.

25

 
 
 
 
 
 
 
We  will  need  to  raise  additional  capital  to  fund  our  planned  future  operations,  and  we  may  be  unable  to  secure  such  capital  without  dilutive
financing  transactions.  If  we  are  not  able  to  raise  additional  capital,  we  may  not  be  able  to  complete  the  development,  testing  and
commercialization of our product candidates.

We have not generated significant revenue and have incurred significant net losses in each year since our inception. For the year ended December 31, 2019,
we had a net loss of $16.9 million and used $20.3 million to fund operations. We have incurred approximately $291 million of accumulated net losses as of
December  31,  2019.  As  of  December  31,  2019,  we  had  approximately  $16.7  million  in  cash,  short-term  investments,  interest  receivable  and  deferred
income tax asset.

We have substantial future capital requirements to continue our research and development activities and advance our product candidates through various
development stages. For example, ThermoDox® is being evaluated in a Phase III clinical trial in combination with RFA for the treatment of primary liver
cancer  and  other  preclinical  studies.  We  completed  a  Phase  I  dose-escalation  clinical  trial  of  GEN-1  in  combination  with  the  standard  of  care  in  neo-
adjuvant ovarian cancer in the third quarter of 2017 and expanded our clinical development program for GEN-1 into a follow-on Phase I/II trial for newly
diagnosed ovarian cancer in 2018.

To complete the development and commercialization of our product candidates, we will need to raise substantial amounts of additional capital to fund our
operations. Our future capital requirements will depend upon numerous unpredictable factors, including, without limitation, the cost, timing, progress and
outcomes of clinical studies and regulatory reviews of our proprietary drug candidates, our efforts to implement new collaborations, licenses and strategic
transactions, general and administrative expenses, capital expenditures and other unforeseen uses of cash. Other than the Capital on Demand Agreement
that provides us the ability to sell equity securities in the future, we do not have any committed sources of financing and cannot assure you that alternate
funding will be available in a timely manner, on acceptable terms or at all. We may need to pursue dilutive equity financings, such as the issuance of shares
of common stock, convertible debt or other convertible or exercisable securities. Such dilutive equity financings could dilute the percentage ownership of
our current common stockholders and could significantly lower the market value of our common stock. In addition, a financing could result in the issuance
of new securities that may have rights, preferences or privileges senior to those of our existing stockholders.

If we are unable to obtain additional capital on a timely basis or on acceptable terms, or, if current market conditions, including the volatility in the markets
resulting from the worldwide Covid-19 pandemic, make capital raising impractical or impossible, we may be required to delay, reduce or terminate our
research  and  development  programs  and  preclinical  studies  or  clinical  trials,  if  any,  limit  strategic  opportunities  or  undergo  corporate  restructuring
activities. We also could be required to seek funds through arrangements with collaborators or others that may require us to relinquish rights to some of our
technologies, product candidates or potential markets or that could impose onerous financial or other terms. Furthermore, if we cannot fund our ongoing
development and other operating requirements, particularly those associated with our obligations to conduct clinical trials under our licensing agreements,
we will be in breach of these licensing agreements and could therefore lose our license rights, which could have material adverse effects on our business.

If we do not obtain or maintain FDA and foreign regulatory approvals for our drug candidates on a timely basis, or at all, or if the terms of any
approval impose significant restrictions or limitations on use, we will be unable to sell those products and our business, results of operations and
financial condition will be negatively affected.

To obtain regulatory approvals from the FDA and foreign regulatory agencies, we must conduct clinical trials demonstrating that our products are safe and
effective. We may need to amend ongoing trials, or the FDA and/or foreign regulatory agencies may require us to perform additional trials beyond those we
planned. The testing and approval process require substantial time, effort and resources, and generally takes a number of years to complete. The time to
complete  testing  and  obtaining  approvals  is  uncertain,  and  the  FDA  and  foreign  regulatory  agencies  have  substantial  discretion,  at  any  phase  of
development, to terminate clinical studies, require additional clinical studies or other testing, delay or withhold approval, and mandate product withdrawals,
including recalls. In addition, our drug candidates may have undesirable side effects or other unexpected characteristics that could cause us or regulatory
authorities to interrupt, delay or halt clinical trials and could result in a more restricted label or the delay or denial of regulatory approval by regulatory
authorities.

Even if we receive regulatory approval of a product, the approval may limit the indicated uses for which the drug may be marketed. The failure to obtain
timely regulatory approval of product candidates, the imposition of marketing limitations, or a product withdrawal would negatively impact our business,
results of operations and financial condition. Even if we receive approval, we will be subject to ongoing regulatory obligations and continued regulatory
review, which may result in significant additional expense and subject us to restrictions, withdrawal from the market, or penalties if we fail to comply with
applicable  regulatory  requirements  or  if  we  experience  unanticipated  problems  with  our  product  candidates,  when  and  if  approved.  Finally,  even  if  we
obtain FDA approval of any of our product candidates, we may never obtain approval or commercialize such products outside of the United States, given
that we may be subject to additional or different regulatory burdens in other markets. This could limit our ability to realize their full market potential.

26

 
 
 
 
 
 
 
 
 
 
Our  industry  is  highly  regulated  by  the  FDA  and  comparable  foreign  regulatory  agencies.  We  must  comply  with  extensive,  strictly  enforced
regulatory requirements to develop, obtain, and maintain marketing approval for any of our product candidates.

Securing FDA or comparable foreign regulatory approval requires the submission of extensive preclinical and clinical data and supporting information for
each therapeutic indication to establish the product candidate’s safety and efficacy for its intended use. It takes years to complete the testing of a new drug
or biological product and development delays and/or failure can occur at any stage of testing. Any of our present and future clinical trials may be delayed,
halted, not authorized, or approval of any of our products may be delayed or may not be obtained due to any of the following:

● any  preclinical  test  or  clinical  trial  may  fail  to  produce  safety  and  efficacy  results  satisfactory  to  the  FDA  or  comparable  foreign  regulatory

authorities;

● preclinical and clinical data can be interpreted in different ways, which could delay, limit or prevent marketing approval;

● negative or inconclusive results from a preclinical test or clinical trial or adverse events during a clinical trial could cause a preclinical study or
clinical trial to be repeated or a development program to be terminated, even if other studies relating to the development program are ongoing or
have been completed and were successful;

● the FDA or comparable foreign regulatory authorities can place a clinical hold on a trial if, among other reasons, it finds that subjects enrolled in

the trial are or would be exposed to an unreasonable and significant risk of illness or injury;

● the FDA or comparable foreign regulatory authorities may suffer delays related to the impact of the spread of COVID-19 on the FDA’s ability to

continue its normal operations

● the facilities that we utilize, or the processes or facilities of third-party vendors, including without limitation the contract manufacturers who will
be manufacturing drug substance and drug product for us or any potential collaborators, may not satisfactorily complete inspections by the FDA or
comparable foreign regulatory authorities; and

● we may encounter delays or rejections based on changes in FDA policies or the policies of comparable foreign regulatory authorities during the
period in which we develop a product candidate, or the period required for review of any final marketing approval before we are able to market
any product candidate.

In  addition,  information  generated  during  the  clinical  trial  process  is  susceptible  to  varying  interpretations  that  could  delay,  limit,  or  prevent  marketing
approval at any stage of the approval process. Moreover, early positive preclinical or clinical trial results may not be replicated in later clinical trials. As
more product candidates within a particular class of drugs proceed through clinical development to regulatory review and approval, the amount and type of
clinical data that may be required by regulatory authorities may increase or change. Failure to demonstrate adequately the quality, safety, and efficacy of
any of our product candidates would delay or prevent marketing approval of the applicable product candidate. We cannot assure you that if clinical trials
are completed, either we or our potential collaborators will submit applications for required authorizations to manufacture or market potential products or
that any such application will be reviewed and approved by appropriate regulatory authorities in a timely manner, if at all.

New gene-based products for therapeutic applications are subject to extensive regulation by the FDA and comparable agencies in other countries.
The precise regulatory requirements with which we will have to comply, now and in the future, are uncertain due to the novelty of the gene-based
products we are developing.

The regulatory approval process for novel product candidates such as ours can be significantly more expensive and take longer than for other, better known
or  more  extensively  studied  product  candidates.  Limited  data  exist  regarding  the  safety  and  efficacy  of  DNA-based  therapeutics  compared  with
conventional therapeutics, and government regulation of DNA-based therapeutics is evolving. Regulatory requirements governing gene and cell therapy
products have changed frequently and may continue to change in the future. The FDA has established the Office of Cellular, Tissue and Gene Therapies
within its Center for Biologics Evaluation and Research (CBER), to consolidate the review of gene therapy and related products, and has established the
Cellular, Tissue and Gene Therapies Advisory Committee to advise CBER in its review. It is difficult to determine how long it will take or how much it will
cost  to  obtain  regulatory  approvals  for  our  product  candidates  in  either  the  U.S.  or  the  European  Union  or  how  long  it  will  take  to  commercialize  our
product candidates.

Adverse events or the perception of adverse events in the field of gene therapy generally, or with respect to our product candidates specifically, may have a
particularly negative impact on public perception of gene therapy and result in greater governmental regulation, including future bans or stricter standards
imposed on gene-based therapy clinical trials, stricter labeling requirements and other regulatory delays in the testing or approval of our potential products.
For example, each clinical trial of investigational gene therapies must be reviewed and approved by the Institutional Biosafety Committee (IBC) for each
clinical  site.  IBCs  were  established  under  the  National  Institutes  of  Health  (NIH)  Guidelines  for  Research  Involving  Recombinant  or  Synthetic  Nucleic
Acid Molecules to provide local review and oversight of nearly all forms of research utilizing recombinant or synthetic nucleic acid molecules. The IBC
assesses biosafety issues, specifically, safety practices and containment procedures, related to the investigational product and clinical study. Compliance
with  the  NIH  Guidelines  is  mandatory  for  investigators  at  institutions  receiving  NIH  funds  for  research  involving  recombinant  DNA,  however  many
companies and other institutions not otherwise subject to the NIH Guidelines voluntarily follow them. Such trials remain subject to FDA and other clinical
trial regulations, and only after FDA, IBC, and other relevant approvals are in place can these protocols proceed. The FDA can put an investigational new
drug  (IND)  application  on  a  clinical  hold  even  if  the  IBC  has  provided  a  favorable  review.  Such  committee  and  advisory  group  reviews  and  any  new
guidelines they promulgate may lengthen the regulatory review process, require us to perform additional studies, increase our development costs, lead to
changes in regulatory positions and interpretations, delay or prevent approval and commercialization of our product candidates or lead to significant post-
approval limitations or restrictions. Any increased scrutiny could delay or increase the costs of our product development efforts or clinical trials.

Even if our products receive regulatory approval, they may still face future development and regulatory difficulties. Government regulators may impose
significant  restrictions  on  a  product’s  indicated  uses  or  marketing  or  impose  ongoing  requirements  for  potentially  costly  post-approval  studies.  This
governmental oversight may be particularly strict with respect to gene-based therapies.

Serious adverse events, undesirable side effects or other unexpected properties of our product candidates may be identified during development or
after  approval,  which  could  lead  to  the  discontinuation  of  our  clinical  development  programs,  refusal  by  regulatory  authorities  to  approve  our
product candidates or, if discovered following marketing approval, revocation of marketing authorizations or limitations on the use of our product
candidates thereby limiting the commercial potential of such product candidate.

As  we  continue  our  development  of  our  product  candidates  and  initiate  clinical  trials  of  our  additional  product  candidates,  serious  adverse  events,
undesirable  side  effects  or  unexpected  characteristics  may  emerge  causing  us  to  abandon  these  product  candidates  or  limit  their  development  to  more
narrow uses or subpopulations in which the serious adverse events, undesirable side effects or other characteristics are less prevalent, less severe or more
acceptable from a risk-benefit perspective.

Even if our product candidates initially show promise in these early clinical trials, the side effects of drugs are frequently only detectable after they are
tested in large, Phase 3 clinical trials or, in some cases, after they are made available to patients on a commercial scale after approval. Sometimes, it can be
difficult  to  determine  if  the  serious  adverse  or  unexpected  side  effects  were  caused  by  the  product  candidate  or  another  factor,  especially  in  oncology
subjects who may suffer from other medical conditions and be taking other medications. If serious adverse or unexpected side effects are identified during
development  and  are  determined  to  be  attributed  to  our  product  candidate,  we  may  be  required  to  develop  a  Risk  Evaluation  and  Mitigation  Strategy
(REMS) to mitigate those serious safety risks, which could impose significant distribution and use restrictions on our products.

In addition, drug-related side effects could also affect subject recruitment or the ability of enrolled subjects to complete the trial, result in potential product
liability  claims,  reputational  harm,  withdrawal  of  approvals,  a  requirement  to  include  additional  warnings  on  the  label  or  to  create  a  medication  guide
outlining the risks of such side effects for distribution to patients. It can also result in patient harm, liability lawsuits, and reputational harm. Any of these
occurrences could prevent us from achieving or maintaining market acceptance and may harm our business, financial condition and prospects significantly.

If  we  encounter  difficulties  enrolling  patients  in  our  clinical  trials,  our  clinical  development  activities  could  be  delayed  or  otherwise  adversely
affected.

We may experience difficulties in patient enrollment in our clinical trials for a variety of reasons. The timely completion of clinical trials in accordance
with their protocols depends, among other things, on our ability to enroll a sufficient number of patients who remain in the trial until its conclusion. The
enrollment of patients depends on many factors, including:

● the patient eligibility and exclusion criteria defined in the protocol;

● the size of the patient population required for analysis of the trial’s primary endpoints and the process for identifying patients;

● the willingness  or  availability  of  patients  to  participate  in  our  trials  (including  due  to  the  recent  outbreak  of  the  coronavirus  strain  known  as

COVID-19, or the COVID-19 coronavirus);

● the proximity of patients to trial sites;

● the design of the trial;

● our ability to recruit clinical trial investigators with the appropriate competencies and experience;

● clinicians’ and patients’ perceptions as to the potential advantages and risks of the product candidate being studied in relation to other available

therapies, including any new products that may be approved for the indications we are investigating;

● the availability of competing commercially available therapies and other competing drug candidates’ clinical trials;

● our ability to obtain and maintain patient informed consents; and

● the risk that patients enrolled in clinical trials will drop out of the trials before completion.

In addition, our clinical trials will compete with other clinical trials for product candidates that are in the same therapeutic areas as our product candidates,
and this competition will reduce the number and types of patients available to us, because some patients who might have opted to enroll in our trials may
instead  opt  to  enroll  in  a  trial  being  conducted  by  one  of  our  competitors.  Since  the  number  of  qualified  clinical  investigators  is  limited,  we  expect  to
conduct  some  of  our  clinical  trials  at  the  same  clinical  trial  sites  that  some  of  our  competitors  use,  which  will  reduce  the  number  of  patients  who  are
available for our clinical trials in such clinical trial site. Certain of our planned clinical trials may also involve invasive procedures, which may lead some
patients to drop out of trials to avoid these follow-up procedures.

Further, timely enrollment in clinical trials is reliant on clinical trial sites which may be adversely affected by global health matters, including, among other
things, pandemics. For example, our clinical trial sites may be located in regions currently being affected by the COVID-19 coronavirus. Some factors from
the COVID-19 coronavirus outbreak that we believe may adversely affect enrollment in our trials include:

● the  diversion  of  healthcare  resources  away  from  the  conduct  of  clinical  trial  matters  to  focus  on  pandemic  concerns,  including  the  attention  of
infectious disease physicians serving as our clinical trial investigators, hospitals serving as our clinical trial sites and hospital staff supporting the
conduct of our clinical trials;

● patients who would otherwise be candidates for enrollment in our clinical trials, may become infected with the COVID-19 coronavirus, which

may kill some patients and render others too ill to participate, limiting the available pool of participants for our trials;

● limitations on travel that interrupt key trial activities, such as clinical trial site initiations and monitoring;

● interruption in global shipping affecting the transport of clinical trial materials, such as investigational drug product and comparator drugs used in

our trials; and

● employee furlough days that delay necessary interactions with local regulators, ethics committees and other important agencies and contractors.

These and other factors arising from the COVID-19 coronavirus could worsen in countries that are already afflicted with the virus or could continue to
spread to additional countries, each of which may further adversely impact our clinical trials. The global outbreak of the COVID-19 coronavirus continues
to evolve and the conduct of our trials may continue to be adversely affected, despite efforts to mitigate this impact.

We may not successfully engage in future strategic transactions, which could adversely affect our ability to develop and commercialize product
candidates, impact our cash position, increase our expense and present significant distractions to our management.

In  the  future,  we  may  consider  strategic  alternatives  intended  to  further  the  development  of  our  business,  which  may  include  acquiring  businesses,
technologies  or  products,  out-  or  in-licensing  product  candidates  or  technologies  or  entering  into  a  business  combination  with  another  company.  Any
strategic transaction may require us to incur non-recurring or other charges, increase our near- and long-term expenditures and pose significant integration
or implementation challenges or disrupt our management or business. These transactions would entail numerous operational and financial risks, including
exposure to unknown liabilities, disruption of our business and diversion of our management’s time and attention in order to manage a collaboration or
develop acquired products, product candidates or technologies, incurrence of substantial debt or dilutive issuances of equity securities to pay transaction
consideration  or  costs,  higher  than  expected  collaboration,  acquisition  or  integration  costs,  write-downs  of  assets  or  goodwill  or  impairment  charges,
increased amortization expenses, difficulty and cost in facilitating the collaboration or combining the operations and personnel of any acquired business,
impairment of relationships with key suppliers, manufacturers or customers of any acquired business due to changes in management and ownership and the
inability to retain key employees of any acquired business. Accordingly, although there can be no assurance that we will undertake or successfully complete
any transactions of the nature described above, any transactions that we do complete may be subject to the foregoing or other risks and have a material
adverse effect on our business, results of operations, financial condition and prospects. Conversely, any failure to enter any strategic transaction that would
be  beneficial  to  us  could  delay  the  development  and  potential  commercialization  of  our  product  candidates  and  have  a  negative  impact  on  the
competitiveness of any product candidate that reaches market.

Strategic transactions, such as acquisitions, partnerships and collaborations, including the EGEN acquisition, involve numerous risks, including:

● the failure of markets for the products of acquired businesses, technologies or product lines to develop as expected;

● uncertainties in identifying and pursuing acquisition targets;

● the challenges in achieving strategic objectives, cost savings and other benefits expected from acquisitions;

● the risk that the financial returns on acquisitions will not support the expenditures incurred to acquire such businesses or the capital expenditures

needed to develop such businesses;

● difficulties in assimilating the acquired businesses, technologies or product lines;

● the failure  to  successfully  manage  additional  business  locations,  including  the  additional  infrastructure  and  resources  necessary  to  support  and

integrate such locations;

● the  existence  of  unknown  product  defects  related  to  acquired  businesses,  technologies  or  product  lines  that  may  not  be  identified  due  to  the

inherent limitations involved in the due diligence process of an acquisition;

● the diversion of management’s attention from other business concerns;

● risks associated with entering markets or conducting operations with which we have no or limited direct prior experience;

● risks associated with assuming the legal obligations of acquired businesses, technologies or product lines;

● risks related to the effect that internal control processes of acquired businesses might have on our financial reporting and management’s report on

our internal control over financial reporting;

● the potential loss of key employees related to acquired businesses, technologies or product lines; and

● the incurrence of significant exit charges if products or technologies acquired in business combinations are unsuccessful.

We may never realize the perceived benefits of the EGEN acquisition or potential future transactions. We cannot assure you that we will be successful in
overcoming  problems  encountered  in  connection  with  any  transactions,  and  our  inability  to  do  so  could  significantly  harm  our  business,  results  of
operations and financial condition. These transactions could dilute a stockholder’s investment in us and cause us to incur debt, contingent liabilities and
amortization/impairment  charges  related  to  intangible  assets,  all  of  which  could  materially  and  adversely  affect  our  business,  results  of  operations  and
financial  condition.  In  addition,  our  effective  tax  rate  for  future  periods  could  be  negatively  impacted  by  the  EGEN  acquisition  or  potential  future
transactions.

Our business depends on license agreements with third parties to permit us to use patented technologies. The loss of any of our rights under these
agreements could impair our ability to develop and market our products.

Our success will depend, in a substantial part, on our ability to maintain our rights under license agreements granting us rights to use patented technologies.
For instance, we are party to license agreements with Duke University, under which we have exclusive rights to commercialize medical treatment products
and  procedures  based  on  Duke’s  thermo-sensitive  liposome  technology.  The  Duke  University  license  agreement  contains  a  license  fee,  royalty  and/or
research support provisions, testing and regulatory milestones, and other performance requirements that we must meet by certain deadlines. If we breach
any provisions of the license and research agreements, we may lose our ability to use the subject technology, as well as compensation for our efforts in
developing or exploiting the technology. Any such loss of rights and access to technology could have a material adverse effect on our business.

Further, we cannot guarantee that any patent or other technology rights licensed to us by others will not be challenged or circumvented successfully by third
parties, or that the rights granted will provide adequate protection. We may be required to alter any of our potential products or processes or enter into a
license and pay licensing fees to a third party or cease certain activities. There can be no assurance that we can obtain a license to any technology that we
determine  we  need  on  reasonable  terms,  if  at  all,  or  that  we  could  develop  or  otherwise  obtain  alternate  technology.  If  a  license  is  not  available  on
commercially  reasonable  terms  or  at  all,  our  business,  results  of  operations,  and  financial  condition  could  be  significantly  harmed,  and  we  may  be
prevented  from  developing  and  commercializing  the  product.  Litigation,  which  could  result  in  substantial  costs,  may  also  be  necessary  to  enforce  any
patents issued to or licensed by us or to determine the scope and validity of another’s claimed proprietary rights.

If  any  of  our  pending  patent  applications  do  not  issue,  or  are  deemed  invalid  following  issuance,  we  may  lose  valuable  intellectual  property
protection.

The patent positions of pharmaceutical and biotechnology companies, such as ours, are uncertain and involve complex legal and factual issues. We own
various U.S. and international patents and have pending U.S. and international patent applications that cover various aspects of our technologies. There can
be no assurance that patents that have issued will be held valid and enforceable in a court of law through the entire patent term. Even for patents that are
held valid and enforceable, the legal process associated with obtaining such a judgment is time consuming and costly. Additionally, issued patents can be
subject to opposition, interferences or other proceedings that can result in the revocation of the patent or maintenance of the patent in amended form (and
potentially in a form that renders the patent without commercially relevant or broad coverage). Further, our competitors may be able to circumvent and
otherwise design around our patents. Even if a patent is issued and enforceable, because development and commercialization of pharmaceutical products
can  be  subject  to  substantial  delays,  patents  may  expire  early  and  provide  only  a  short  period  of  protection,  if  any,  following  the  commercialization  of
products encompassed by our patents. We may have to participate in interference proceedings declared by the U.S. Patent and Trademark Office, which
could result in a loss of the patent and/or substantial cost to us.

We have filed patent applications, and plan to file additional patent applications, covering various aspects of our technologies and our proprietary product
candidates. There can be no assurance that the patent applications for which we apply would actually issue as patents or do so with commercially relevant
or broad coverage. The coverage claimed in a patent application can be significantly reduced before the patent is issued. The scope of our claim coverage
can  be  critical  to  our  ability  to  enter  into  licensing  transactions  with  third  parties  and  our  right  to  receive  royalties  from  our  collaboration  partnerships.
Since publication of discoveries in scientific or patent literature often lags behind the date of such discoveries, we cannot be certain that we were the first
inventor of inventions covered by our patents or patent applications. In addition, there is no guarantee that we will be the first to file a patent application
directed to an invention.

31

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
An adverse outcome in any judicial proceeding involving intellectual property, including patents, could subject us to significant liabilities to third parties,
require disputed rights to be licensed from or to third parties or require us to cease using the technology in dispute. In those instances where we seek an
intellectual property license from another, we may not be able to obtain the license on a commercially reasonable basis, if at all, thereby raising concerns on
our ability to freely commercialize our technologies or products.

We rely on trade secret protection and other unpatented proprietary rights for important proprietary technologies, and any loss of such rights
could harm our business, results of operations and financial condition.

We  rely  on  trade  secrets  and  confidential  information  that  we  seek  to  protect,  in  part,  by  confidentiality  agreements  with  our  corporate  partners,
collaborators, employees and consultants. We cannot assure you that these agreements are adequate to protect our trade secrets and confidential information
or  will  not  be  breached  or,  if  breached,  we  will  have  adequate  remedies.  Furthermore,  others  may  independently  develop  substantially  equivalent
confidential and proprietary information or otherwise gain access to our trade secrets or disclose such technology. Any loss of trade secret protection or
other unpatented proprietary rights could harm our business, results of operations and financial condition.

Our  products  may  infringe  patent  rights  of  others,  which  may  require  costly  litigation  and,  if  we  are  not  successful,  could  cause  us  to  pay
substantial damages or limit our ability to commercialize our products.

Our commercial success depends on our ability to operate without infringing the patents and other proprietary rights of third parties. There may be third
party patents that relate to our products and technology. We may unintentionally infringe upon valid patent rights of third parties. Although we currently are
not  involved  in  any  material  litigation  involving  patents,  a  third-party  patent  holder  may  assert  a  claim  of  patent  infringement  against  us  in  the  future.
Alternatively, we may initiate litigation against the third-party patent holder to request that a court declare that we are not infringing the third party’s patent
and/or that the third party’s patent is invalid or unenforceable. If a claim of infringement is asserted against us and is successful, and therefore we are found
to infringe, we could be required to pay damages for infringement, including treble damages if it is determined that we knew or became aware of such a
patent and we failed to exercise due care in determining whether or not we infringed the patent. If we have supplied infringing products to third parties or
have licensed third parties to manufacture, use or market infringing products, we may be obligated to indemnify these third parties for damages they may
be required to pay to the patent holder and for any losses they may sustain.

We can also be prevented from selling or commercializing any of our products that use the infringing technology in the future, unless we obtain a license
from  such  third  party.  A  license  may  not  be  available  from  such  third  party  on  commercially  reasonable  terms  or  may  not  be  available  at  all.  Any
modification  to  include  a  non-infringing  technology  may  not  be  possible,  or  if  possible,  may  be  difficult  or  time-consuming  to  develop,  and  require
revalidation, which could delay our ability to commercialize our products. Any infringement action asserted against us, even if we are ultimately successful
in  defending  against  such  action,  would  likely  delay  the  regulatory  approval  process  of  our  products,  harm  our  competitive  position,  be  expensive  and
require the time and attention of our key management and technical personnel.

We rely on third parties to conduct all of our clinical trials. If these third parties are unable to carry out their contractual duties in a manner that
is consistent with our expectations, comply with budgets and other financial obligations or meet expected deadlines, we may not receive certain
development  milestone  payments  or  be  able  to  obtain  regulatory  approval  for  or  commercialize  our  product  candidates  in  a  timely  or  cost-
effective manner.

We do not independently conduct clinical trials for our drug candidates. We rely, and expect to continue to rely, on third-party clinical investigators, clinical
research organizations (CROs), clinical data management organizations and consultants to design, conduct, supervise and monitor our clinical trials.

Because we do not conduct our own clinical trials, we must rely on the efforts of others and have reduced control over aspects of these activities, including,
the timing of such trials, the costs associated with such trials and the procedures that are followed for such trials. We do not expect to significantly increase
our  personnel  in  the  foreseeable  future  and  may  continue  to  rely  on  third  parties  to  conduct  all  of  our  future  clinical  trials.  If  we  cannot  contract  with
acceptable third parties on commercially reasonable terms or at all, if these third parties are unable to carry out their contractual duties or obligations in a
manner that is consistent with our expectations or meet expected deadlines, if they do not carry out the trials in accordance with budgeted amounts, if the
quality or accuracy of the clinical data they obtain is compromised due to their failure to adhere to our clinical protocols or for other reasons, or if they fail
to maintain compliance with applicable government regulations and standards, our clinical trials may be extended, delayed or terminated or may become
significantly more expensive, we may not receive development milestone payments when expected or at all, and we may not be able to obtain regulatory
approval for or successfully commercialize our product candidates.

32

 
 
 
 
 
 
 
 
 
 
 
Despite our reliance on third parties to conduct our clinical trials, we are ultimately responsible for ensuring that each of our clinical trials is conducted in
accordance with the general investigational plan and protocols for the trial. Moreover, the FDA requires clinical trials to be conducted in accordance with
good clinical practices for conducting, recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate
and that the rights, integrity and confidentiality of clinical trial participants are protected. We also are required to register ongoing clinical trials and post the
results of completed clinical trials on a government-sponsored database, ClinicalTrials.gov, within certain timeframes. Failure to do so can result in fines,
adverse  publicity  and  civil  and  criminal  sanctions.  Our  reliance  on  third  parties  that  we  do  not  control  does  not  relieve  us  of  these  responsibilities  and
requirements. If we or a third party we rely on fails to meet these requirements, we may not be able to obtain, or may be delayed in obtaining, marketing
authorizations for our drug candidates and will not be able to, or may be delayed in our efforts to, successfully commercialize our drug candidates. This
could have a material adverse effect on our business, financial condition, results of operations and prospects.

Because we rely on third party manufacturing and supply partners, our supply of research and development, preclinical and clinical development
materials may become limited or interrupted or may not be of satisfactory quantity or quality.

We rely on third party supply and manufacturing partners to supply the materials and components for, and manufacture, our research and development,
preclinical and clinical trial drug supplies. We do not own manufacturing facilities or supply sources for such components and materials. There can be no
assurance  that  our  supply  of  research  and  development,  preclinical  and  clinical  development  drugs  and  other  materials  will  not  be  limited,  interrupted,
restricted in certain geographic regions or of satisfactory quality or continue to be available at acceptable prices. Suppliers and manufacturers must meet
applicable  manufacturing  requirements  and  undergo  rigorous  facility  and  process  validation  tests  required  by  FDA  and  foreign  regulatory  authorities  in
order to comply with regulatory standards, such as current Good Manufacturing Practices. In the event that any of our suppliers or manufacturers fails to
comply  with  such  requirements  or  to  perform  its  obligations  to  us  in  relation  to  quality,  timing  or  otherwise,  or  if  our  supply  of  components  or  other
materials becomes limited or interrupted for other reasons, we may be forced to manufacture the materials ourselves, for which we currently do not have
the capabilities or resources, or enter into an agreement with another third party, which we may not be able to do on reasonable terms, if at all.

Our  business  is  subject  to  numerous  and  evolving  state,  federal  and  foreign  regulations  and  we  may  not  be  able  to  secure  the  government
approvals needed to develop and market our products.

Our research and development activities, pre-clinical tests and clinical trials, and ultimately the manufacturing, marketing and labeling of our products, are
all  subject  to  extensive  regulation  by  the  FDA  and  foreign  regulatory  agencies.  Pre-clinical  testing  and  clinical  trial  requirements  and  the  regulatory
approval process typically take years and require the expenditure of substantial resources. Additional government regulation may be established that could
prevent or delay regulatory approval of our product candidates. Delays or rejections in obtaining regulatory approvals would adversely affect our ability to
commercialize any product candidates and our ability to generate product revenue or royalties.

The  FDA  and  foreign  regulatory  agencies  require  that  the  safety  and  efficacy  of  product  candidates  be  supported  through  adequate  and  well-controlled
clinical trials. If the results of pivotal clinical trials do not establish the safety and efficacy of our product candidates to the satisfaction of the FDA and
other foreign regulatory agencies, we will not receive the approvals necessary to market such product candidates. Even if regulatory approval of a product
candidate is granted, the approval may include significant limitations on the indicated uses for which the product may be marketed.

We  are  subject  to  the  periodic  inspection  of  our  clinical  trials,  facilities,  procedures  and  operations  and/or  the  testing  of  our  products  by  the  FDA  to
determine whether our systems and processes, or those of our vendors and suppliers, are in compliance with FDA regulations. Following such inspections,
the FDA may issue notices on Form 483 and warning letters that could cause us to modify certain activities identified during the inspection.

Failure  to  comply  with  the  FDA  and  other  governmental  regulations  can  result  in  fines,  unanticipated  compliance  expenditures,  recall  or  seizure  of
products,  total  or  partial  suspension  of  production  and/or  distribution,  suspension  of  the  FDA’s  review  of  product  applications,  enforcement  actions,
injunctions  and  criminal  prosecution.  Under  certain  circumstances,  the  FDA  also  has  the  authority  to  revoke  previously  granted  product  approvals.
Although we have internal compliance programs, if these programs do not meet regulatory agency standards or if our compliance is deemed deficient in
any significant way, it could have a material adverse effect on the Company.

33

 
 
 
 
 
 
 
 
 
 
We are also subject to recordkeeping and reporting regulations. These regulations require, among other things, the reporting to the FDA of adverse events
alleged  to  have  been  associated  with  the  use  of  a  product  or  in  connection  with  certain  product  failures.  Labeling  and  promotional  activities  also  are
regulated  by  the  FDA.  We  must  also  comply  with  record  keeping  requirements  as  well  as  requirements  to  report  certain  adverse  events  involving  our
products.  The  FDA  can  impose  other  post-marketing  controls  on  us  as  well  as  our  products  including,  but  not  limited  to,  restrictions  on  sale  and  use,
through the approval process, regulations and otherwise.

Many states in which we do or may do business, or in which our products may be sold, if at all, impose licensing, labeling or certification requirements that
are in addition to those imposed by the FDA. There can be no assurance that one or more states will not impose regulations or requirements that have a
material adverse effect on our ability to sell our products.

In  many  of  the  foreign  countries  in  which  we  may  do  business  or  in  which  our  products  may  be  sold,  we  will  be  subject  to  regulation  by  national
governments and supranational agencies as well as by local agencies affecting, among other things, product standards, packaging requirements, labeling
requirements, import restrictions, tariff regulations, duties and tax requirements. There can be no assurance that one or more countries or agencies will not
impose regulations or requirements that could have a material adverse effect on our ability to sell our products.

We have obtained Orphan Drug Designation for ThermoDox® and may seek Orphan Drug Designation for other product candidates, but we may
be  unsuccessful  or  may  be  unable  to  maintain  the  benefits  associated  with  Orphan  Drug  Designation,  including  the  potential  for  market
exclusivity.

ThermoDox® has been granted orphan drug designation for primary liver cancer in both the U.S. and Europe. As part of our business strategy, we may
seek Orphan Drug Designation for other product candidates, but we may be unsuccessful. Regulatory authorities in some jurisdictions, including the U.S.
and Europe, may designate drugs for relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a drug as an
orphan drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals
annually in the U.S., or a patient population greater than 200,000 in the U.S. where there is no reasonable expectation that the cost of developing the drug
will be recovered from sales in the U.S.

Even  though  we  have  obtained  Orphan  Drug  Designation  for  ThermoDox®  and  may  obtain  such  designation  for  other  product  candidates  in  specific
indications, we may not be the first to obtain marketing approval of these product candidates for the orphan-designated indication due to the uncertainties
associated  with  developing  pharmaceutical  products.  In  addition,  exclusive  marketing  rights  in  the  U.S.  may  be  limited  if  we  seek  approval  for  an
indication  broader  than  the  orphan-designated  indication  or  may  be  lost  if  the  FDA  later  determines  that  the  request  for  designation  was  materially
defective  or  if  the  manufacturer  is  unable  to  assure  sufficient  quantities  of  the  product  to  meet  the  needs  of  patients  with  the  rare  disease  or  condition.
Further, even if we obtain orphan drug exclusivity for a product, that exclusivity may not effectively protect the product from competition because different
drugs with different active moieties can be approved for the same condition. Even after an orphan product is approved, the FDA can subsequently approve
the  same  drug  with  the  same  active  moiety  for  the  same  condition  if  the  FDA  concludes  that  the  later  drug  is  safer,  more  effective  or  makes  a  major
contribution to patient care. Orphan Drug Designation neither shortens the development time or regulatory review time of a drug nor gives the drug any
advantage in the regulatory review or approval process. In addition, while we may seek Orphan Drug Designation for other product candidates, we may
never receive such designations.

Fast Track designation may not actually lead to a faster development or regulatory review or approval process.

ThermoDox®  has  received  U.S.  FDA  Fast  Track  Designation.  However,  we  may  not  experience  a  faster  development  process,  review,  or  approval
compared  to  conventional  FDA  procedures.  The  FDA  may  withdraw  our  Fast  Track  designation  if  the  FDA  believes  that  the  designation  is  no  longer
supported by data from our clinical or pivotal development program. Our Fast Track designation does not guarantee that we will qualify for or be able to
take advantage of the FDA’s expedited review procedures or that any application that we may submit to the FDA for regulatory approval will be accepted
for filing or ultimately approved.

Our relationships with healthcare providers and physicians and third-party payors will be subject to applicable anti-kickback, fraud and abuse
and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm
and diminished profits and future earnings.

Healthcare providers, physicians and third-party payors in the United States and elsewhere play a primary role in the recommendation and prescription of
biopharmaceutical products. Arrangements with third-party payors and customers can expose biopharmaceutical manufacturers to broadly applicable fraud
and  abuse  and  other  healthcare  laws  and  regulations,  including,  without  limitation,  the  federal  Anti-Kickback  Statute  and  the  federal  False  Claims  Act,
which may constrain the business or financial arrangements and relationships through which such companies sell, market and distribute biopharmaceutical
products. In particular, the research of our product candidates, as well as the promotion, sales and marketing of healthcare items and services, as well as
certain business arrangements in the healthcare industry, are subject to extensive laws designed to prevent fraud, kickbacks, self-dealing and other abusive
practices.  These  laws  and  regulations  may  restrict  or  prohibit  a  wide  range  of  pricing,  discounting,  marketing  and  promotion,  structuring  and
commission(s), certain customer incentive programs and other business arrangements generally. Activities subject to these laws also involve the improper
use of information obtained in the course of patient recruitment for clinical trials. The applicable federal, state and foreign healthcare laws and regulations
laws that may affect our ability to operate include, but are not limited to:

● the  federal  Anti-Kickback  Statute,  which  prohibits,  among  other  things,  knowingly  and  willfully  soliciting,  receiving,  offering  or  paying  any
remuneration (including any kickback, bribe, or rebate), 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,  or  the  purchase,  lease,  order  or  recommendation  of  any  good,  facility,  item  or  service  for  which
payment may be made, in whole or in part, under a federal healthcare program, such as the Medicare and Medicaid programs. A person or entity
can be found guilty of violating the statute without actual knowledge of the statute or specific intent to violate it. In addition, a claim submitted for
payment to any federal health care program that includes items or services that were made as a result of a violation of the federal Anti-Kickback
Statute  constitutes  a  false  or  fraudulent  claim  for  purposes  of  the  federal  False  Claims  Act,  or  FCA.  The  Anti-Kickback  Statute  has  been
interpreted  to  apply  to  arrangements  between  biopharmaceutical  manufacturers  on  the  one  hand  and  prescribers,  purchasers,  and  formulary
managers, among others, on the other. There are a number of statutory exceptions and regulatory safe harbors protecting some common activities
from prosecution;

● the  federal  civil  and  criminal  false  claims  laws,  including  the  FCA,    and  civil  monetary  penalty  laws  which  prohibit,  among  other  things,
individuals or entities from knowingly presenting, or causing to be presented, false, fictious or fraudulent claims for payment to, or approval by
Medicare, Medicaid, or other federal healthcare programs; knowingly making, using or causing to be made or used a false record or statement
material to a false or fraudulent claim or an obligation to pay or transmit money or property to the federal government; or knowingly concealing or
knowingly  and  improperly  avoiding  or  decreasing  or  concealing  an  obligation  to  pay  money  to  the  federal  government.  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  FCA.
Manufacturers can be held liable under the FCA even when they do not submit claims directly to government payors if they are deemed to “cause”
the submission of false or fraudulent claims. The FCA also permits a private individual acting as a “whistleblower” to bring qui tam actions on
behalf of the federal government alleging violations of the FCA and to share in any monetary recovery;

● the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created additional federal criminal statutes that prohibit
knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of false or
fraudulent  pretenses,  representations,  or  promises,  any  of  the  money  or  property  owned  by,  or  under  the  custody  or  control  of,  any  healthcare
benefit program, regardless of the payor (e.g., public or private) and knowingly and willfully falsifying, concealing or covering up by any trick or
device a material fact or making any materially false statements in connection with the delivery of, or payment for, healthcare benefits, items or

without actual knowledge of the statute or specific intent to violate it;

● HIPAA, as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act  of  2009,  or  HITECH,  and  their  respective

identifiable health information on certain covered healthcare providers, health plans, and healthcare clearinghouses, known as covered entities, as
well as their respective “business associates,” those independent contractors or agents of covered entities that perform services for covered entities
that involve the creation, use, receipt, maintenance or disclosure of individually identifiable health information. HITECH also created 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 courts to enforce the federal HIPAA laws and seek attorneys’ fees
and costs associated with pursuing federal civil actions;

● the federal  Physician  Payments  Sunshine  Act,  created  under  the  ACA,  and  its  implementing  regulations,  which  require  some  manufacturers  of

Program  (with  certain  exceptions)  to  report  annually  to  CMS  information  related  to  payments  or  other  transfers  of  value  made  to  physicians
(defined  to  include  doctors,  dentists,  optometrists,  podiatrists  and  chiropractors)  and  teaching  hospitals,  as  well  as  ownership  and  investment

transfers of value made in the previous year to certain non-physician providers such as physician assistants and nurse practitioners;

● federal  consumer  protection  and  unfair  competition  laws,  which  broadly  regulate  marketplace  activities  and  activities  that  potentially  harm

consumers; and

● analogous  state  and  foreign  laws  and  regulations,  such  as  state  anti-kickback  and  false  claims  laws,  which  may  apply  to  sales  or  marketing
arrangements and claims involving healthcare items or services reimbursed by third-party payors, including private insurers, and may be broader
in  scope  than  their  federal  equivalents;  state  and  foreign  laws  that  require  biopharmaceutical  companies  to  comply  with  the  biopharmaceutical
industry’s  voluntary  compliance  guidelines  and  the  relevant  compliance  guidance  promulgated  by  the  federal  government  or  otherwise  restrict
payments that may be made to healthcare providers and other potential referral sources; state and foreign laws that require drug manufacturers to
report information related to payments and other transfers of value to physicians and other healthcare providers, marketing expenditures or drug
pricing;  state  and  local  laws  that  require  the  registration  of  biopharmaceutical  sales  representatives;  and  state  and  foreign  laws  governing  the
privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and often are not
preempted by HIPAA, thus complicating compliance efforts.

The distribution of biopharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping, licensing, storage
and security requirements intended to prevent the unauthorized sale of biopharmaceutical products.

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. Ensuring business arrangements comply with applicable healthcare laws, as well as responding to
possible investigations by government authorities, can be time- and resource-consuming and can divert a company’s attention from the business.

It  is  possible  that  governmental  and  enforcement  authorities  will  conclude  that  our  business  practices  may  not  comply  with  current  or  future  statutes,
regulations or case law interpreting applicable fraud and abuse or other healthcare laws and regulations. If any such actions are instituted against us, and we
are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of
significant  civil,  criminal  and  administrative  penalties,  damages,  fines,  disgorgement,  imprisonment,  reputational  harm,  possible  exclusion  from
participation in federal and state funded healthcare programs, contractual damages and the curtailment or restricting 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.  Further,  if  any  of  the  physicians  or  other  healthcare  providers  or  entities  with  whom  we  expect  to  do  business  is  found  to  be  not  in
compliance  with  applicable  laws,  they  may  be  subject  to  significant  criminal,  civil  or  administrative  sanctions,  including  exclusions  from  government
funded healthcare programs. Any action for violation of these laws, even if successfully defended, could cause a biopharmaceutical manufacturer to incur
significant legal expenses and divert management’s attention from the operation of the business. Prohibitions or restrictions on sales or withdrawal of future
marketed products could materially affect business in an adverse way.

Ongoing legislative and regulatory changes affecting the healthcare industry could have a material adverse effect on our business.

Political,  economic  and  regulatory  influences  are  subjecting  the  healthcare  industry  to  potential  fundamental  changes  that  could  substantially  affect  our
results of operations by requiring, for example: (i) changes to our manufacturing arrangements; (ii) additions or modifications to product labeling; (iii) the
recall or discontinuation of our products; or (iv) additional record-keeping requirements.

In the United States, there have been and continue to be a number of legislative initiatives to contain healthcare costs. For example, in March 2010, the
ACA was passed, which substantially changed the way health care is financed by both governmental and private insurers, and significantly impacted the
U.S.  biopharmaceutical  industry.  The  ACA,  among  other  things,  addressed  a  new  methodology  by  which  rebates  owed  by  manufacturers  under  the
Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected, increased the minimum Medicaid rebates
owed  by  manufacturers  under  the  Medicaid  Drug  Rebate  Program  and  extended  the  rebate  program  to  individuals  enrolled  in  Medicaid  managed  care
organizations, established annual fees and taxes on manufacturers of certain branded prescription drugs, and created a new Medicare Part D coverage gap
discount program, in which manufacturers must agree to offer 70% (increased pursuant to the Bipartisan Budget Act of 2018, effective as of 2019) point-
of-sale  discounts  off  negotiated  prices  of  applicable  brand  drugs  to  eligible  beneficiaries  during  their  coverage  gap  period,  as  a  condition  for  the
manufacturer’s outpatient drugs to be covered under Medicare Part D.

Since  its  enactment,  some  of  the  provisions  of  the  ACA  have  yet  to  be  fully  implemented,  while  certain  provisions  have  been  subject  to  judicial,
congressional, and executive challenges. As a result, there have been delays in the implementation of, and action taken to repeal or replace, certain aspects
of the ACA. Since January 2017, President Trump has signed two Executive Orders 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.  One  Executive  Order  directs  federal  agencies  with
authorities and responsibilities under the ACA to waive, defer, grant exemptions from, or delay the implementation of any provision of the ACA that would
impose a fiscal or regulatory burden on states, individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals or medical devices.
The second Executive Order terminates the cost-sharing subsidies that reimburse insurers under the ACA. Several state Attorneys General filed suit to stop
the administration from terminating the subsidies, but their request for a restraining order was denied by a federal judge in California on October 25, 2017.
The loss of the cost share reduction payments is expected to increase premiums on certain policies issued by qualified health plans under the ACA. Further,
on June 14, 2018, U.S. Court of Appeals for the Federal Circuit ruled that the federal government was not required to pay more than $12 billion in ACA
risk corridor payments to third-party payors who argued were owed to them. On December 10, 2019, the U.S. Supreme Court heard arguments in Moda
Health Plan, Inc. v. United States, which will determine whether the government must make risk corridor payments. The U.S. Supreme Court’s decision
will be released in the coming months, but we cannot predict how the U.S. Supreme Court will rule. The effects of this gap in reimbursement on third-party
payors, the viability of the ACA marketplace, providers, and potentially our business, are not yet known. While Congress has not passed comprehensive
repeal legislation, it has enacted laws that modify certain provisions of the Affordable Care Act such as removing penalties, starting January 1, 2019, for
not complying with the Affordable Care Act’s individual mandate to carry health insurance, delaying the implementation of certain Affordable Care Act-
mandated fees, and increasing the point-of-sale discount that is owed by pharmaceutical manufacturers who participate in Medicare Part D. On December
14,  2018,  a  Texas  U.S.  District  Court  Judge  ruled  that  the  ACA  is  unconstitutional  in  its  entirety  because  the  “individual  mandate”  was  repealed  by
Congress  as  part  of  the  Tax  Cuts  and  Jobs  Act  of  2017.  Additionally,  on  December  18,  2019,  the  U.S.  Court  of  Appeals  for  the  5th  Circuit  upheld  the
District Court ruling that the individual mandate was unconstitutional and remanded the case back to the District Court to determine whether the remaining
provisions of the ACA are invalid as well. On March 2, 2020, the United States Supreme Court granted the petitions for writs of certiorari to review this
case, and has allotted one hour for oral arguments, which are expected to occur in the fall. We cannot predict what affect further changes to the ACA would
have on our business.

36

 
 
 
 
 
 
 
 
 
Other legislative changes have been proposed and adopted in the United States since the ACA was enacted. The Budget Control Act of 2011, among other
things,  created  measures  for  spending  reductions  by  Congress.  A  Joint  Select  Committee  on  Deficit  Reduction,  tasked  with  recommending  a  targeted
deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic
reduction to several government programs, including aggregate reductions of Medicare payments to providers of 2% per fiscal year. These reductions went
into effect on April 1, 2013 and, due to subsequent legislative amendments to the statute, including the Bipartisan Budget Act of 2018, or BBA, will remain
in effect through 2029, unless additional congressional action is taken. The BBA also amended the ACA, effective January 1, 2019, by increasing the point-
of-sale discount that is owed by pharmaceutical manufacturers who participate in Medicare Part D and closing the coverage gap in most Medicare drug
plans, commonly referred to as the “donut hole”. On January 2, 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other
things, further reduced Medicare payments to several types of providers, including hospitals, imaging centers and cancer treatment centers, and increased
the statute of limitations period for the government to recover overpayments to providers from three to five years.

Moreover,  increasing  efforts  by  governmental  and  third-party  payors  in  the  United  States  and  abroad  to  cap  or  reduce  healthcare  costs  may  cause  such
organizations to limit both coverage and the level of reimbursement for newly approved products and, as a result, they may not cover or provide adequate
payment  for  our  product  candidates.  There  has  been  increasing  legislative  and  enforcement  interest  in  the  United  States  with  respect  to  specialty  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. Several states have adopted price
transparency  requirements  and  those  as  well  as  any  future  federal  price  transparency  requirements  that  may  be  implemented  in  the  future  could  have  a
negative  effect  on  our  business.  Additionally,  we  expect  to  experience  pricing  pressures  in  connection  with  the  sale  of  any  future  approved  product
candidates  due  to  the  trend  toward  managed  healthcare,  the  increasing  influence  of  health  maintenance  organizations,  cost  containment  initiatives  and
additional legislative changes.

At the federal level, the Trump administration’s budget for fiscal year 2021 includes a $135 billion allowance to support legislative proposals seeking to
reduce drug prices, increase competition, lower out-of-pocket drug costs for patients, and increase patient access to lower-cost generic and biosimilar drugs.
The Trump administration previously released a “Blueprint” to lower drug prices and reduce out of pocket costs of drugs that contains additional proposals
to  increase  manufacturer  competition,  increase  the  negotiating  power  of  certain  federal  healthcare  programs,  incentivize  manufacturers  to  lower  the  list
price of their products and reduce the out of pocket costs of drug products paid by consumers. The U.S. Department of Health and Human Services, or
HHS, has solicited feedback on some of these measures and has implemented others under its existing authority. For example, in May 2019, CMS issued a
final rule that would allow Medicare Advantage Plans the option of using step therapy, a type of prior authorization, for Part B drugs beginning January 1,
2020.  This  final  rule  codified  CMS’s  policy  change  that  was  effective  January  1,  2019. Although  a  number  of  these  and  other  measures  may  require
additional authorization to become effective, Congress and the Trump administration have each indicated that it will continue to seek new legislative and/or
administrative  measures  to  control  drug  costs.  Any  reduction  in  reimbursement  from  Medicare  and  other  government  programs  may  result  in  a  similar
reduction in payments from private payers. In addition, individual states in the United States have also increasingly passed legislation and implemented
regulations  designed  to  control  pharmaceutical  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.

At the state level, legislatures are increasingly passing legislation and implementing regulations designed to control biopharmaceutical and biologic 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.

We cannot predict what healthcare reform initiatives may be adopted in the future. Further, federal and state legislative and regulatory developments are
likely, and we expect ongoing initiatives in the United States to increase pressure on drug pricing. Such reforms could have an adverse effect on anticipated
revenues from reloxaliase and any other product candidates that we may successfully develop and for which we may obtain regulatory approval and may
affect our overall financial condition and ability to develop product candidates.

We may fail to comply with evolving European and other privacy laws.

Since  we  conduct  clinical  trials  in  the  European  Economic  Area  (“EEA”),  we  are  subject  to  additional  European  data-privacy  laws.  The  General  Data
Protection  Regulation,  (EU)  2016/679  (“GDPR”)  became  effective  on  May  25,  2018  and  deals  with  the  processing  of  personal  data  and  on  the  free
movement of such data. The GDPR imposes a broad range of strict requirements on companies subject to the GDPR, including requirements relating to
having legal bases for processing personal information relating to identifiable individuals and transferring such information outside the EEA, including to
the United States, providing details to those individuals regarding the processing of their personal information, keeping personal information secure, having
data processing agreements with third parties who process personal information, responding to individuals’ requests to exercise their rights in respect of
their personal information, reporting security breaches involving personal data to the competent national data protection authority and affected individuals,
appointing data protection officers, conducting data protection impact assessments, and record-keeping. The GDPR increases substantially the penalties to
which  we  could  be  subject  in  the  event  of  any  non-compliance,  including  fines  of  up  to  10,000,000  Euros  or  up  to  2%  of  our  total  worldwide  annual
turnover for certain comparatively minor offenses, or up to 20,000,000 Euros or up to 4% of our total worldwide annual turnover for more serious offenses.
Given the limited enforcement of the GDPR to date, we face uncertainty as to the exact interpretation of the new requirements on our trials and we may be
unsuccessful in implementing all measures required by data protection authorities or courts in interpretation of the new law.

37

 
 
 
 
 
 
 
 
 
In particular, national laws of member states of the EU are in the process of being adapted to the requirements under the GDPR, thereby implementing
national laws which may partially deviate from the GDPR and impose different obligations from country to country, so that we do not expect to operate in a
uniform legal landscape in the EEA. Also, as it relates to processing and transfer of genetic data, the GDPR specifically allows national laws to impose
additional and more specific requirements or restrictions, and European laws have historically differed quite substantially in this field, leading to additional
uncertainty.  Further,  the  United  Kingdom’s  decision  to  leave  the  EU,  often  referred  to  as  Brexit,  has  created  uncertainty  with  regard  to  data  protection
regulation in the United Kingdom. In particular, it is unclear how data transfers to and from the United Kingdom will be regulated now that the United
Kingdom has left the EU.

In the event we continue to conduct clinical trials in the EEA, we must also ensure that we maintain adequate safeguards to enable the transfer of personal
data  outside  of  the  EEA,  in  particular  to  the  United  States,  in  compliance  with  European  data  protection  laws.  We  expect  that  we  will  continue  to  face
uncertainty as to whether our efforts to comply with our obligations under European privacy laws will be sufficient. If we are investigated by a European
data protection authority, we may face fines and other penalties. Anype1 such investigation or charges by European data protection authorities could have a
negative effect on our existing business and on our ability to attract and retain new clients or pharmaceutical partners. We may also experience hesitancy,
reluctance, or refusal by European or multi-national clients or pharmaceutical partners to continue to use our products and solutions due to the potential risk
exposure  as  a  result  of  the  current  (and,  in  particular,  future)  data  protection  obligations  imposed  on  them  by  certain  data  protection  authorities  in
interpretation  of  current  law,  including  the  GDPR.  Such  clients  or  pharmaceutical  partners  may  also  view  any  alternative  approaches  to  compliance  as
being too costly, too burdensome, too legally uncertain, or otherwise objectionable and therefore decide not to do business with us. Any of the foregoing
could materially harm our business, prospects, financial condition and results of operations

The  success  of  our  products  may  be  harmed  if  the  government,  private  health  insurers  and  other  third-party  payers  do  not  provide  sufficient
coverage or reimbursement.

Our ability to commercialize our new cancer treatment systems successfully will depend in part on the extent to which reimbursement for the costs of such
products and related treatments will be available from third-party payors, which include government authorities such as Medicare, Medicaid, TRICARE,
and the Veterans Administration, managed care providers, private health insurers, and other organizations. Patients who are provided medical treatment for
their  conditions  generally  rely  on  third-party  payors  to  reimburse  all  or  part  of  the  costs  associated  with  their  treatment.  Coverage  and  adequate
reimbursement  from  governmental  healthcare  programs,  such  as  Medicare  and  Medicaid,  and  commercial  payors  is  critical  to  new  product  acceptance.
Patients are unlikely to use our product candidates unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost. The
reimbursement status of newly approved medical products is subject to significant uncertainty We cannot be sure that coverage and reimbursement will be
available for, or accurately estimate the potential revenue from, our product candidates or assure that coverage and reimbursement will be available for any
product that we may develop.

Government authorities and other third-party payors decide which drugs and treatments they will cover and the amount of reimbursement. In the United
States, the principal decisions about reimbursement for new medicines are typically made by the Centers for Medicare & Medicaid Services, or CMS, an
agency  within  the  U.S.  Department  of  Health  and  Human  Services.  CMS  decides  whether  and  to  what  extent  a  new  medicine  will  be  covered  and
reimbursed under Medicare and private payors tend to follow CMS to a substantial degree. No uniform policy of coverage and reimbursement for drug
products  exists  among  third-party  payors.  Therefore,  coverage  and  reimbursement  for  drug  products  can  differ  significantly  from  payor  to  payor.  The
process  for  determining  whether  a  third-party  payor  will  provide  coverage  for  a  product  may  be  separate  from  the  process  for  setting  the  price  or
reimbursement rate that the payor will pay for the product once coverage is approved. Coverage and reimbursement by a third-party payor may depend
upon a number of factors, including the third-party payor’s determination that use of a product is:

● a covered benefit under its health plan;
● safe, effective and medically necessary;
● appropriate for the specific patient;
● cost-effective; and
● neither experimental nor investigational.

In  order  to  secure  coverage  and  reimbursement  for  any  product  that  might  be  approved  for  sale,  a  company  may  need  to  conduct  expensive
pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of the product, in addition to the costs required to obtain
FDA  or  other  comparable  regulatory  approvals.  Additionally,  companies  may  also  need  to  provide  discounts  to  purchasers,  private  health  plans  or
government healthcare programs. Nonetheless, product candidates may not be considered medically necessary or cost effective. A decision by a third-party
payor not to cover a product could reduce physician utilization once the product is approved and have a material adverse effect on sales, our operations and
financial condition.

Government, private health insurers and other third-party payors are increasingly attempting to contain healthcare costs by limiting both coverage and the
level of reimbursement for new therapeutic products approved for marketing by the FDA. For example, Congress passed the Affordable Care Act in 2010
which enacted a number of reforms to expand access to health insurance while also reducing or constraining the growth of healthcare spending, enhancing
remedies against fraud and abuse, adding new transparency requirements for healthcare industries, and imposing new taxes on fees on healthcare industry
participants,  among  other  policy  reforms.  Federal  agencies,  Congress  and  state  legislatures  have  continued  to  show  interest  in  implementing  cost
containment  programs  to  limit  the  growth  of  health  care  costs,  including  price  controls,  price  disclosures,  restrictions  on  reimbursement  and  other
fundamental changes to the healthcare delivery system. In addition, in recent years, Congress has enacted various laws seeking to reduce the federal debt
level and contain healthcare expenditures, and the Medicare and other healthcare programs are frequently identified as potential targets for spending cuts.
New government legislation or regulations related to pricing or other fundamental changes to the healthcare delivery system as well as a government or
third-party  payer  decision  not  to  approve  pricing  for,  or  provide  adequate  coverage  or  reimbursement  of,  our  product  candidates  hold  the  potential  to
severely limit market opportunities of such products. Accordingly, even if coverage and reimbursement are provided by government, private health insurers
and third-party payors for uses of our products, market acceptance of these products would be adversely affected if the reimbursement available proves to
be unprofitable for health care providers.

Our products may not achieve sufficient acceptance by the medical community to sustain our business.

The  commercial  success  of  our  products  will  depend  upon  their  acceptance  by  the  medical  community  and  third-party  payors  as  clinically  useful,  cost
effective and safe. Any of our drug candidates or similar product candidates being investigated by our competitors may prove not to be effective in trial or
in practice, cause adverse events or other undesirable side effects. Our testing and clinical practice may not confirm the safety and efficacy of our product
candidates  or  even  if  further  testing  and  clinical  practice  produce  positive  results,  the  medical  community  may  view  these  new  forms  of  treatment  as

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
effective and desirable or our efforts to market our new products may fail. Market acceptance depends upon physicians and hospitals obtaining adequate
reimbursement rates from third-party payors to make our products commercially viable. Any of these factors could have an adverse effect on our business,
financial condition and results of operations.

38

 
The commercial potential of a drug candidate in development is difficult to predict. If the market size for a new drug is significantly smaller than
we anticipate, it could significantly and negatively impact our revenue, results of operations and financial condition.

It is very difficult to predict the commercial potential of product candidates due to important factors such as safety and efficacy compared to other available
treatments,  including  potential  generic  drug  alternatives  with  similar  efficacy  profiles,  changing  standards  of  care,  third  party  payor  reimbursement
standards, patient and physician preferences, the availability of competitive alternatives that may emerge either during the long drug development process
or after commercial introduction, and the availability of generic versions of our successful product candidates following approval by government health
authorities based on the expiration of regulatory exclusivity or our inability to prevent generic versions from coming to market by asserting our patents. If
due to one or more of these risks the market potential for a drug candidate is lower than we anticipated, it could significantly and negatively impact the
revenue potential for such drug candidate and would adversely affect our business, financial condition and results of operations.

Several of our current clinical trials are being conducted outside the United States, and the FDA may not accept data from trials conducted in
foreign locations.

Several  of  our  current  clinical  trials  are  being  conducted  outside  the  United  States.  Although  the  FDA  may  accept  data  from  clinical  trials  conducted
outside  the  United  States,  acceptance  of  these  data  is  subject  to  certain  conditions  imposed  by  the  FDA.  For  example,  the  clinical  trial  must  be  well
designed and conducted and performed by qualified investigators in accordance with ethical principles. The trial population must also adequately represent
the U.S. population, and the data must be applicable to the U.S. population and U.S. medical practice in ways that the FDA deems clinically meaningful. In
general, the patient population for any clinical trials conducted outside of the United States must be representative of the population for whom we intend to
label the product in the United States. In addition, while these clinical trials are subject to the applicable local laws, FDA acceptance of the data will be
dependent upon its determination that the trials also complied with all applicable U.S. laws and regulations. We cannot assure you that the FDA will accept
data from trials conducted outside of the United States. If the FDA does not accept the data from such clinical trials, it would likely result in the need for
additional trials, which would be costly and time-consuming and delay or permanently halt our development of our product candidates.

We have no internal sales or marketing capability. If we are unable to create sales, marketing and distribution capabilities or enter into alliances
with others possessing such capabilities to perform these functions, we will not be able to commercialize our products successfully.

We  currently  have  no  sales,  marketing  or  distribution  capabilities.  We  intend  to  market  our  products,  if  and  when  such  products  are  approved  for
commercialization by the FDA and foreign regulatory agencies, either directly or through other strategic alliances and distribution arrangements with third
parties. If we decide to market our products directly, we will need to commit significant financial and managerial resources to develop a marketing and
sales  force  with  technical  expertise  and  with  supporting  distribution,  administration  and  compliance  capabilities.  If  we  rely  on  third  parties  with  such
capabilities to market our products, we will need to establish and maintain partnership arrangements, and there can be no assurance that we will be able to
enter into third-party marketing or distribution arrangements on acceptable terms or at all. To the extent that we do enter into such arrangements, we will be
dependent on our marketing and distribution partners. In entering into third-party marketing or distribution arrangements, we expect to incur significant
additional  expenses  and  there  can  be  no  assurance  that  such  third  parties  will  establish  adequate  sales  and  distribution  capabilities  or  be  successful  in
gaining market acceptance for our products and services.

Technologies for the treatment of cancer are subject to rapid change, and the development of treatment strategies that are more effective than our
technologies could render our technologies obsolete.

Various methods for treating cancer currently are, and in the future, are expected to be, the subject of extensive research and development. Many possible
treatments that are being researched, if successfully developed, may not require, or may supplant, the use of our technologies. The successful development
and acceptance of any one or more of these alternative forms of treatment could render our technology obsolete as a cancer treatment method.

We  may  not  be  able  to  hire  or  retain  key  officers  or  employees  that  we  need  to  implement  our  business  strategy  and  develop  our  product
candidates and business, including those purchased in the EGEN asset acquisition.

Our success depends significantly on the continued contributions of our executive officers, scientific and technical personnel and consultants, including
those retained in the EGEN acquisition, and on our ability to attract additional personnel as we seek to implement our business strategy and develop our
product candidates and businesses. Our operations associated with the EGEN acquisition are located in Huntsville, Alabama. Key employees may depart if
we fail to successfully manage this additional business location or in relation to any uncertainties or difficulties of integration with Celsion. We cannot
guarantee that we will retain key employees to the same extent that we and EGEN retained each of our own employees in the past, which could have a
negative impact on our business, results of operations and financial condition. Our integration of EGEN and ability to operate in the fields we acquired
from EGEN may be more difficult if we lose key employees. Additionally, during our operating history, we have assigned many essential responsibilities to
a relatively small number of individuals. However, as our business and the demands on our key employees expand, we have been, and will continue to be,
required to recruit additional qualified employees. The competition for such qualified personnel is intense, and the loss of services of certain key personnel
or our inability to attract additional personnel to fill critical positions could adversely affect our business. Further, we do not carry “key man” insurance on
any of our personnel. Therefore, loss of the services of key personnel would not be ameliorated by the receipt of the proceeds from such insurance.

Our success will depend in part on our ability to grow and diversify, which in turn will require that we manage and control our growth effectively.

Our business strategy contemplates growth and diversification. Our ability to manage growth effectively will require that we continue to expend funds to
improve our operational, financial and management controls, reporting systems and procedures. In addition, we must effectively expand, train and manage
our employees. We will be unable to manage our business effectively if we are unable to alleviate the strain on resources caused by growth in a timely and
successful manner. There can be no assurance that we will be able to manage our growth and a failure to do so could have a material adverse effect on our
business.

We face intense competition and the failure to compete effectively could adversely affect our ability to develop and market our products.

There  are  many  companies  and  other  institutions  engaged  in  research  and  development  of  various  technologies  for  cancer  treatment  products  that  seek
treatment  outcomes  similar  to  those  that  we  are  pursuing.  We  believe  that  the  level  of  interest  by  others  in  investigating  the  potential  of  possible
competitive treatments and alternative technologies will continue and may increase. Potential competitors engaged in all areas of cancer treatment research
in  the  U.S.  and  other  countries  include,  among  others,  major  pharmaceutical,  specialized  technology  companies,  and  universities  and  other  research
institutions. Most of our current and potential competitors have substantially greater financial, technical, human and other resources, and may also have far
greater experience than do we, both in pre-clinical testing and human clinical trials of new products and in obtaining FDA and other regulatory approvals.
One or more of these companies or institutions could succeed in developing products or other technologies that are more effective than the products and
technologies that we have been or are developing, or which would render our technology and products obsolete and non-competitive. Furthermore, if we
are permitted to commence commercial sales of any of our products, we will also be competing, with respect to manufacturing efficiency and marketing,
with companies having substantially greater resources and experience in these areas.

We may be subject to significant product liability claims and litigation.

Our  business  exposes  us  to  potential  product  liability  risks  inherent  in  the  testing,  manufacturing  and  marketing  of  human  therapeutic  products.  We
presently have product liability insurance limited to $10 million per incident and $10 million annually. If we were to be subject to a claim in excess of this
coverage or to a claim not covered by our insurance and the claim succeeded, we would be required to pay the claim with our own limited resources, which
could have a severe adverse effect on our business. Whether or not we are ultimately successful in any product liability litigation, such litigation would
harm the business by diverting the attention and resources of our management, consuming substantial amounts of our financial resources and by damaging
our reputation. Additionally, we may not be able to maintain our product liability insurance at an acceptable cost, if at all.

We or the third parties upon whom we depend may be adversely affected by earthquakes, global pandemics or other natural disasters and our
business continuity and disaster recovery plans may not adequately protect us from a serious disaster, including earthquakes, outbreak of disease
or other natural disasters.

Our current operations are located in our facilities in Lawrenceville, New Jersey. Any unplanned event, such as flood, fire, explosion, earthquake, extreme
weather condition, medical epidemics, power shortage, telecommunication failure or other natural or manmade accidents or incidents that result in us being
unable to fully utilize our facilities, or the manufacturing facilities of our third-party contract manufacturers, may have a material and adverse effect on our
ability to operate our business, particularly on a daily basis, and have significant negative consequences on our financial and operating conditions. Loss of
access  to  these  facilities  may  result  in  increased  costs,  delays  in  the  development  of  our  product  candidates  or  interruption  of  our  business  operations.
Earthquakes  or  other  natural  disasters  could  further  disrupt  our  operations  and  have  a  material  and  adverse  effect  on  our  business,  financial  condition,
results of operations and prospects. If a natural disaster, power outage or other event occurred that prevented us from using all or a significant portion of
our  headquarters,  that  damaged  critical  infrastructure,  such  as  our  research  facilities  or  the  manufacturing  facilities  of  our  third-party  contract
manufacturers, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible, for us to continue our business for a substantial
period of time. For example, in December 2019, an outbreak of a novel strain of coronavirus, or the COVID-19 coronavirus, originated in Wuhan, China.
To date, this outbreak has already resulted in extended shutdowns of certain businesses in the Wuhan region and has had ripple effects to businesses around
the world. An outbreak of communicable diseases in China or elsewhere, or the perception that such an outbreak could occur, and the measures taken by
the governments of countries affected, could adversely affect our business, financial condition or results of operations by limiting our ability to manufacture
products within or outside China, forcing temporary closure of facilities that we rely upon or increasing the costs associated with obtaining clinical supplies
of  our  product  candidates.  The  extent  to  which  the  COVID-19  coronavirus  impacts  our  results  will  depend  on  future  developments,  which  are  highly
uncertain and cannot be accurately predicted, including new information which may emerge concerning the severity of the COVID-19 coronavirus and the
actions to contain the COVID-19 coronavirus or treat its impact, among others. Global health concerns, such as the COVID-19 coronavirus, could also
result in social, economic, and labor instability in the countries in which we or the third parties with whom we engage operate.

The disaster recovery and business continuity plans we have in place may prove inadequate in the event of a serious disaster or similar event. We may incur
substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans, which, could have a material adverse effect on
our business. As part of our risk management policy, we maintain insurance coverage at levels that we believe are appropriate for our business. However, in
the event of an accident or incident at these facilities, we cannot assure you that the amounts of insurance will be sufficient to satisfy any damages and
losses. If our facilities, or the manufacturing facilities of our third-party contract manufacturers, are unable to operate because of an accident or incident or
for any other reason, even for a short period of time, any or all of our research and development programs may be harmed.

Our internal computer systems, or those of our CROs or other contractors or consultants, may fail or suffer security breaches, which could result
in a material disruption of our product development programs.

Despite  the  implementation  of  security  measures,  our  internal  computer  systems  and  those  of  our  CROs  and  other  contractors  and  consultants  are
vulnerable  to  damage  from  computer  viruses,  unauthorized  access,  natural  disasters,  terrorism,  war  and  telecommunication  and  electrical  failures.  Such
events could cause interruptions of our operations. For instance, the loss of preclinical data or data from any clinical trial involving our product candidates
could result in delays in our development and regulatory filing efforts and significantly increase our costs. To the extent that any disruption or privacy or
security breach were to result in a loss of, or damage to, our data, or inappropriate disclosure of confidential or proprietary information, we could be subject
to reputational harm, monetary fines, civil suits, civil penalties or criminal sanctions and requirements to disclose the breach, and other forms of liability
and the development of our product candidates could be delayed.

Pandemics such as the COVID-19 coronavirus could have an adverse impact on our developmental programs and our financial condition.

In  December  2019,  a  novel  strain  of  the  COVID-19  coronavirus  was  first  identified  in  Wuhan,  Hubei  Province,  China.  Any  outbreak  of  contagious
diseases, or other adverse public health developments, could have a material and adverse effect on our business operations. These could include disruptions
or restrictions on our ability to travel, pursue partnerships and other business transactions, conduct clinical trials, make shipments of biologic materials, as
well as be impacted by the temporary closure of the facilities of suppliers and clinical trial sites. Any disruption of suppliers, clinical trial sites or access to
patients would likely impact our clinical trial enrollment progress and rates as well as our ability to access capital through the financial markets. The extent
to  which  the  COVID-19  coronavirus  impacts  our  business  will  depend  on  future  developments,  which  are  highly  uncertain  and  cannot  be  predicted,
including new information which may emerge concerning the severity of the COVID-19 coronavirus and the actions to contain the COVID-19 coronavirus
or treat its impact, among others.

RISKS RELATED TO OUR SECURITIES

The  market  price  of  our  common  stock  has  been,  and  may  continue  to  be  volatile  and  fluctuate  significantly,  which  could  result  in  substantial
losses for investors and subject us to securities class action litigation.

The trading price for our common stock has been, and we expect it to continue to be, volatile. The price at which our common stock trades depends upon a
number of factors, including our historical and anticipated operating results, our financial situation, announcements of technological innovations or new
products by us or our competitors, our ability or inability to raise the additional capital we may need and the terms on which we raise it, and general market
and economic conditions. Some of these factors are beyond our control. Broad market fluctuations may lower the market price of our common stock and
affect the volume of trading in our stock, regardless of our financial condition, results of operations, business or prospect. The closing price of our common
stock as reported on The Nasdaq Capital Market had a high price of $3.48 and a low price of $1.35 in the 52-week period ended December 31, 2018, a high
price of $2.47 and a low price of $1.08 in the 52-week period ended December 31, 2019, and a high price of $1.73 and a low price of $0.72 from January 1,
2020 through March 24, 2020. Among the factors that may cause the market price of our common stock to fluctuate are the risks described in this “Risk
Factors” section and other factors, including:

● results of preclinical and clinical studies of our product candidates or those of our competitors;

● regulatory or legal developments in the U.S. and other countries, especially changes in laws and regulations applicable to our product candidates;

● actions taken by regulatory agencies with respect to our product candidates, clinical studies, manufacturing process or sales and marketing terms;

● introductions and announcements of new products by us or our competitors, and the timing of these introductions or announcements;

● announcements by us or our competitors of significant acquisitions or other strategic transactions or capital commitments;

● fluctuations in our quarterly operating results or the operating results of our competitors;

● variance in our financial performance from the expectations of investors;

● changes in the estimation of the future size and growth rate of our markets;

● changes in accounting principles or changes in interpretations of existing principles, which could affect our financial results;

● failure of our products to achieve or maintain market acceptance or commercial success;

● conditions and trends in the markets we serve;

● changes in general economic, industry and market conditions;

● success of competitive products and services;

● changes in market valuations or earnings of our competitors;

● changes in our pricing policies or the pricing policies of our competitors;

● changes in legislation or regulatory policies, practices or actions;

● the commencement or outcome of litigation involving our company, our general industry or both;

● recruitment or departure of key personnel;

● changes in our capital structure, such as future issuances of securities or the incurrence of additional debt;

● actual  or  anticipated  changes  in  earnings  estimates  or  changes  in  stock  market  analyst  recommendations  regarding  our  common  stock,  other

comparable companies or our industry generally;

● actual or expected sales of our common stock by our stockholders;

● acquisitions and financings, including the EGEN acquisition; and

● the trading volume of our common stock.

In addition, the stock markets, in general, The Nasdaq Capital Market and the market for pharmaceutical companies in particular, may experience a loss of
investor  confidence.  Such  loss  of  investor  confidence  may  result  in  extreme  price  and  volume  fluctuations  in  our  common  stock  that  are  unrelated  or
disproportionate to the operating performance of our business, financial condition or results of operations. These broad market and industry factors may
materially harm the market price of our common stock and expose us to securities class action litigation. Such litigation, even if unsuccessful, could be
costly to defend and divert management’s attention and resources, which could further materially harm our financial condition and results of operations.

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

Sales of a substantial number of shares of our common stock in the public market, or the perception that these sales might occur, could depress the market
price  of  our  common  stock  and  could  impair  our  ability  to  raise  capital  through  the  sale  of  additional  equity  securities.  As  of  March  24,  2020,  we  had
29,257,101  shares  of  common  stock  outstanding,  all  of  which,  other  than  shares  held  by  our  directors  and  certain  officers,  were  eligible  for  sale  in  the
public market, subject in some cases to compliance with the requirements of Rule 144, including the volume limitations and manner of sale requirements.
In addition, all of the shares of common stock issuable upon exercise of warrants will be freely tradable without restriction or further registration upon
issuance.

Our stockholders may experience significant dilution as a result of future equity offerings or issuances and exercise of outstanding options and
warrants.

In order to raise additional capital or pursue strategic transactions, we may in the future offer, issue or sell additional shares of our common stock or other
securities  convertible  into  or  exchangeable  for  our  common  stock,  including  the  issuance  of  common  stock  in  relation  to  the  achievement,  if  any,  of
milestones  triggering  our  payment  of  earn-out  consideration  in  connection  with  the  EGEN  acquisition.  Our  stockholders  may  experience  significant
dilution as a result of future equity offerings or issuances. Investors purchasing shares or other securities in the future could have rights superior to existing
stockholders. As of March 24, 2020, we have a significant number of securities convertible into, or allowing the purchase of, our common stock, including
3,826,098  shares  of  common  stock  issuable  upon  exercise  of  warrants  outstanding,  4,786,747  options  to  purchase  shares  of  our  common  stock  and
restricted stock awards outstanding, and 4,152 shares of common stock reserved for future issuance under our stock incentive plan.

The adverse capital and credit market conditions could affect our liquidity.

Adverse capital and credit market conditions could affect our ability to meet liquidity needs, as well as our access to capital and cost of capital. The capital
and credit markets have experienced extreme volatility and disruption in recent years. Our results of operations, financial condition, cash flows and capital
position could be materially adversely affected by continued disruptions in the capital and credit markets.

Our ability to use net operating losses to offset future taxable income are subject to certain limitations.

On December 22, 2017, the President of the United States signed into law the Tax Reform Act. The Tax Reform Act significantly changes U.S. tax law by,
among other things, lowering corporate income tax rates, implementing a quasi-territorial tax system, providing a one-time transition toll charge on foreign
earnings, creating a new limitation on the deductibility of interest expenses and modifying the limitation on officer compensation. The Tax Reform Act
permanently  reduces  the  U.S.  corporate  income  tax  rate  from  a  maximum  of  35%  to  a  flat  21%  rate,  effective  January  1,  2018.  We  currently  have
significant net operating losses (NOLs) that may be used to offset future taxable income. In general, under Section 382 of the Internal Revenue Code of
1986, as amended (the Code), a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its pre-change NOLs to
offset future taxable income. During 2019, 2018 and years prior, we performed analyses to determine if there were changes in ownership, as defined by
Section 382 of the Internal Revenue Code that would limit our ability to utilize certain net operating loss and tax credit carry forwards. We determined we
experienced ownership changes, as defined by Section 382, in connection with certain common stock offerings in 2011, 2013, 2015, 2017 and 2018. As a
result, the utilization of our federal tax net operating loss carry-forwards generated prior to the ownership changes is limited. Future changes in our stock
ownership, some of which are outside of our control, could result in an ownership change under Section 382 of the Code, which would significantly limit
our ability to utilize NOLs to offset future taxable income.

We have never paid cash dividends on our common stock in the past and do not anticipate paying cash dividends on our common stock in the
foreseeable future.

We  have  never  declared  or  paid  cash  dividends  on  our  common  stock.  We  do  not  anticipate  paying  any  cash  dividends  on  our  common  stock  in  the
foreseeable  future.  We  currently  intend  to  retain  all  available  funds  and  any  future  earnings  to  fund  the  development  and  growth  of  our  business.  As  a
result, capital appreciation, if any, of our common stock will be the sole source of gain for the foreseeable future for holders of our common stock.

Anti-takeover provisions in our charter documents and Delaware law could prevent or delay a change in control.

Our  certificate  of  incorporation  and  bylaws  may  discourage,  delay  or  prevent  a  merger  or  acquisition  that  a  stockholder  may  consider  favorable  by
authorizing the issuance of “blank check” preferred stock. This preferred stock may be issued by our Board of Directors on such terms as it determines,
without further stockholder approval. Therefore, our Board of Directors may issue such preferred stock on terms unfavorable to a potential bidder in the
event that our Board of Directors opposes a merger or acquisition. In addition, our Board of Directors may discourage such transactions by increasing the
amount of time necessary to obtain majority representation on our Board of Directors. Certain other provisions of our bylaws and of Delaware law may
also discourage, delay or prevent a third party from acquiring or merging with us, even if such action were beneficial to some, or even a majority, of our
stockholders.

PROPERTIES

In  July  2011,  we  entered  into  a  lease  with  Brandywine  Operating  Partnership,  L.P.,  a  Delaware  limited  partnership  for  a  10,870  square  foot  premises
located in Lawrenceville, New Jersey in connection with the relocation of our offices from Columbia, Maryland. In late 2015, Lenox Drive Office Park
LLC, purchased the real estate and office building and assumed the lease. Under the current terms of the lease, which was amended effective May 1, 2017
and  is  set  to  expire  on  September  1,  2022,  we  reduced  the  size  of  the  premises  to  7,565  square  feet  and  are  paying  a  monthly  rent  that  ranges  from
approximately $18,900 in the first year to approximately $20,500 in the final year of the amendment. On February 1, 2019, we amended the current terms
of the lease to increase the size of the premises by 2,285 square feet to 9,850 square feet and also extended the lease term by one year to September 1, 2023.
In conjunction with the February 1, 2019 lease amendment, we agreed to modify our one-time option to cancel the lease as of the 36th month after the May
1, 2017 lease commencement date.

In connection with the Asset Purchase Agreement, in June 2014, we assumed the existing lease with another landlord for an 11,500 square foot premises
located  in  Huntsville,  Alabama.  In  January  2018,  we  entered  into  a  new  60-month  lease  agreement  for  9,049  square  feet  with  rent  payments  of
approximately $18,100 per month.

LEGAL PROCEEDINGS

On September 20, 2019, a purported stockholder of the Company filed a derivative and putative class action lawsuit in the Superior Court of New Jersey,
Chancery  Division,  against  the  Company  (as  both  a  class  action  defendant  and  nominal  defendant),  certain  officers  and  directors),  with  the  caption
O’Connor v. Braun et al., Docket No. MER-C-000068-19 (the “Shareholder Action”). The Shareholder Action alleges breaches of the defendants’ fiduciary
based on allegations that the Defendants made or approved improper statements when seeking shareholder approval of the 2018 Stock Incentive Plan. The
Shareholder Action seeks, among other things, any damages sustained by the Company as a result of the defendants’ alleged wrongdoing, a declaratory
judgment against all defendants invalidating the 2018 Stock Incentive Plan and declaring any awards made under the Plan invalid, rescinded, and subject to
disgorgement,  an  order  disgorging  the  equity  awards  granted  to  the  individual  defendants  under  the  2018  Stock  Incentive  Plan,  and  attorneys’  fees  and

Overview

Celsion  is  an  integrated  development  clinical  stage  oncology  drug  company  focused  on  advancing  innovative  cancer  treatments,  including  directed
chemotherapies,  DNA-mediated  immunotherapy  and  RNA-based  therapies.  Our  lead  product  candidate  is  ThermoDox®,  a  proprietary  heat-activated
liposomal encapsulation of doxorubicin, currently in a Phase III clinical trial for the treatment of primary liver cancer (the “OPTIMA Study”). Second in
our product pipeline is GEN-1, a DNA-mediated immunotherapy for the localized treatment of ovarian cancer. These investigational products are based on
platform technologies that provide the basis for future development of a range of therapeutics, largely focused on difficult-to-treat forms of cancer. The first
platform  technology  is  Lysolipid  Thermally  Sensitive  Liposomes,  a  heat  sensitive  liposomal  based  dosage  form  that  is  designed  to  target  disease  with
known chemotherapeutics in the presence of mild heat. The second platform technology is TheraPlas, a novel nucleic acid-based investigational candidate
under development for local transfection of therapeutic DNA plasmids. Employing these technologies, we are working to develop and commercialize more
efficient, effective and targeted oncology therapies that maximize efficacy while minimizing side effects common to cancer treatments.

ThermoDox®

ThermoDox®  is  being  evaluated  in  a  Phase  III  clinical  trial  for  primary  liver  cancer,  which  we  call  the  OPTIMA  Study,  which  was  initiated  in  2014.
ThermoDox® is a liposomal encapsulation of doxorubicin, an approved and frequently used oncology drug for the treatment of a wide range of cancers.
Localized  heat  at  hyperthermia  temperatures  (greater  than  40°  Celsius)  releases  the  encapsulated  doxorubicin  from  the  liposome  enabling  high
concentrations of doxorubicin to be deposited preferentially in and around the targeted tumor.

The  OPTIMA  Study.  The  OPTIMA  Study  represents  an  evaluation  of  ThermoDox®  in  combination  with  a  first  line  therapy,  radio  frequency  ablation
(“RFA”),  for  newly  diagnosed,  intermediate  stage  HCC  patients.  HCC  incidence  globally  is  approximately  755,000  new  cases  per  year  and  is  the  third
largest cancer indication globally. Approximately 30% of newly diagnosed patients can be addressed with RFA alone.

On February 24, 2014, we announced that the United States Food and Drug Administration (the “FDA”) provided clearance for the OPTIMA Study, which
is  a  pivotal,  double-blind,  placebo-controlled  Phase  III  trial  of  ThermoDox®,  in  combination  with  standardized  RFA,  for  the  treatment  of  primary  liver
cancer. The trial design of the OPTIMA Study is based on the comprehensive analysis of data from an earlier clinical trial conducted by the Company
called  the  HEAT  Study  (the  “HEAT  Study”). The  OPTIMA  Study  is  supported  by  a  hypothesis  developed  from  an  overall  survival  analysis  of  a  large
subgroup of 285 patients from the HEAT Study.

Post-hoc data analysis from our earlier Phase III HEAT Study suggest that ThermoDox® may substantially improve OS, when compared to the control
group, in patients if their lesions undergo a 45-minute RFA procedure standardized for a lesion greater than 3 cm in diameter. Data from nine OS sweeps
have been conducted since the top line progression free survival (“PFS”) data from the HEAT Study were announced in January 2013, with each data set
demonstrating substantial improvement in clinical benefit over the control group with statistical significance. On August 15, 2016, we announced updated
results from its final retrospective OS analysis of the data from the HEAT Study (the “HEAT Study subgroup”). These results demonstrated that in a large,
well  bounded,  subgroup  of  patients  with  a  single  lesion  (n=285,  41%  of  the  HEAT  Study  patients),  treatment  with  a  combination  of  ThermoDox®  and
optimized RFA provided an average 54% risk improvement in OS compared to optimized RFA alone. The Hazard Ratio (“HR”) at this analysis is 0.65
(95% CI 0.45 - 0.94) with a p-value of 0.02. Median OS for the ThermoDox® subgroup has been reached which translates into a two-year survival benefit
over the optimized RFA subgroup (projected to be greater than 80 months for the ThermoDox® plus optimized RFA subgroup compared to less than 60
months projection for the optimized RFA only subgroup).

While this information should be viewed with caution since it is based on a retrospective analysis of a subgroup, we also conducted additional analyses that
further strengthen the evidence for the HEAT Study subgroup. We commissioned an independent computational model at the University of South Carolina
Medical School. The results unequivocally indicate that longer RFA heating times correlate with significant increases in doxorubicin concentration around
the  RFA  treated  tissue.  In  addition,  we  conducted  a  prospective  preclinical  study  in  22  pigs  using  two  different  manufacturers  of  RFA  and  human
equivalent doses of ThermoDox® that clearly support the relationship between increased heating duration and doxorubicin concentrations.

The OPTIMA Study was designed with extensive input from globally recognized HCC researchers and expert clinicians. The FDA also provided formal
written  feedback  to  the  Company  on  the  study  protocol  and  trial  design.  The  OPTIMA  Study  was  designed  to  enroll  up  to  550  patients  globally  at
approximately  65  clinical  sites  in  the  U.S.,  Canada,  European  Union  (EU),  China  and  other  countries  in  the  Asia-Pacific  region  and  will  evaluate
ThermoDox® in combination with standardized RFA, which will require a minimum of 45 minutes across all investigators and clinical sites for treating
lesions three to seven centimeters, versus standardized RFA alone. The primary endpoint for this clinical trial is overall survival (“OS”), and the secondary
endpoints  are  progression  free  survival  and  safety.  The  statistical  plan  calls  for  two  interim  efficacy  analyses  by  an  independent  Data  Monitoring
Committee (“DMC”).

We completed enrollment of 556 patients in the Phase III OPTIMA Study in August 2018. Data for the study will be reviewed as it matures up to two
interim  analyses  expected  to  be  conducted  in  the  second  half  of  2019  and  in  mid-2020.  We  expect  that  the  final  efficacy  analysis,  if  necessary,  will  be
completed in early 2021. ThermoDox® has received U.S. FDA Fast Track Designation and has been granted orphan drug designation for primary liver
cancer in both the U.S. and the EU. Additionally, the U.S. FDA has provided ThermoDox® with a 505(b)(2) registration pathway. Subject to a successful
trial,  the  OPTIMA  Study  has  been  designed  to  support  registration  in  all  key  primary  liver  cancer  markets.  We  fully  expect  to  submit  registrational
applications in the U.S., Europe and China. We expect to submit and believe that applications will be accepted in South Korea, Taiwan and Vietnam, three
other significant markets for ThermoDox® if it were to receive approval in Europe, China or the U.S.

On December 18, 2018, we announced that the DMC for the OPTIMA Study completed its last scheduled review of all patients enrolled in the trial and
unanimously recommended that the OPTIMA Study continue according to protocol to its final data readout. The DMC’s recommendation was based on the
Committee’s assessment of safety and data integrity of all patients randomized in the trial as of October 4, 2018. The DMC reviewed study data at regular
intervals throughout the patient enrollment period, with the primary responsibilities of ensuring the safety of all patients enrolled in the study, the quality of
the  data  collected,  and  the  continued  scientific  validity  of  the  study  design.  As  part  of  its  review  of  all  556  patients  enrolled  into  the  trial,  the  DMC
evaluated  a  quality  matrix  relating  to  the  total  clinical  data  set,  confirming  the  timely  collection  of  data,  that  all  data  are  current  as  well  as  other  data
collection and quality criteria.

On August 5, 2019, the Company announced that the prescribed number of OS events had been reached for the first prespecified interim analysis of the
OPTIMA Phase III Study. Following preparation of the data, the first interim analysis was conducted by the DMC on November 1, 2019. This timeline was
consistent  with  the  Company’s  stated  expectations  and  is  necessary  to  provide  a  full  and  comprehensive  data  set  that  may  represent  the  potential  for  a
successful trial outcome. In accordance with the statistical plan, this initial interim analysis has a target of 118 events, or 60% of the total number required
for  the  final  analysis.  At  the  time  of  the  data  cutoff,  the  Company  received  reports  of  128  events.  The  hazard  ratio  for  success  at  128  events  is
approximately 0.63, which represents a 37% reduction in the risk of death compared with RFA alone and is consistent with the 0.65 hazard ratio that was
observed in the prospective HEAT Study subgroup, which demonstrated a two-year overall survival advantage and a median time to death of more than
seven and a half years.

On  November  4,  2019,  the  Company  announced  that  the  DMC  unanimously  recommended  the  OPTIMA  Study  continue  according  to  protocol.  The
recommendation  was  based  on  a  review  of  blinded  safety  and  data  integrity  from  556  patients  enrolled  in  the  Company’s  multinational,  double-blind,
placebo-controlled  pivotal  Phase  III  OPTIMA  Study.  The  DMC’s  pre-planned  interim  efficacy  review  followed  128  patient  events,  or  deaths,  which
occurred  in  August  2019.  Data  presented  demonstrated  that  PFS  and  OS  data  appear  to  be  tracking  with  patient  data  observed  at  a  similar  point  in  the
Company’s subgroup of patients followed prospectively in the earlier Phase III HEAT Study, upon which the OPTIMA Study is based.

The data review demonstrated the following:

● The OPTIMA Study patient demographics and risk factors are consistent with what the Company observed in the HEAT Study subgroup with all

data quality metrics meeting expectations.

● Median PFS for the OPTIMA Study reached 17 months as of August 2019. These blinded data compare favorably with 16 months median PFS for

all 285 patients in the HEAT Study subgroup of patients treated with RFA >45 minutes.

● Median OS for the OPTIMA Study has not been reached as of August 5, 2019, however median OS appears to be consistent with the HEAT Study

subgroup of patients treated with RFA >45 minutes and followed prospectively for overall survival.

● The OPTIMA Study has lost only 4 patients to follow-up from the initiation of the trial in September 2014 through August 2019 while the trial

design allows for 3% risk for loss per year, which at this point would have exceeded 60 patients.

While the Company has not unblinded the study to report a hazard ratio, PFS and OS are tracking similarly to the subgroup of patients who received more
than 45 minutes of RFA in our HEAT Study and followed prospectively for more than three years. This subgroup in the HEAT Study demonstrated a 2-year
overall survival advantage and a median time to death of more than 7 ½ years. This tracking appears to bode well for success at the second of two pre-
planned interim efficacy analysis, which is intended after a minimum of 158 patient deaths and is projected to occur during the second quarter of 2020. The
hazard ratio for success at 158 events is 0.70. This is below the hazard ratio of 0.65 observed in the HEAT Study subgroup of patients treated with RFA >
45 minutes.

The HEAT Study. On January 31, 2013, we announced that ThermoDox® in combination with radio frequency ablation (“RFA”) did not meet the primary
endpoint of progression free survival (“PFS”) for the 701-patient clinical trial in patients with hepatocellular carcinoma (HCC), also known as primary liver
cancer  (the  HEAT  Study).  We  determined,  after  conferring  with  the  HEAT  Study’s  independent  DMC,  that  the  HEAT  Study  did  not  meet  the  goal  of
demonstrating persuasive evidence of clinical effectiveness, that being a clinically meaningful improvement in progression free survival (PFS), that could
form  the  basis  for  regulatory  approval.  In  the  trial,  ThermoDox®  was  well-tolerated  with  no  unexpected  serious  adverse  events.  Following  the
announcement of the HEAT Study results, we continued to follow patients for overall survival (OS), the secondary endpoint of the HEAT Study. We have
conducted a comprehensive analysis of the data from the HEAT Study to assess the future strategic value and development strategy for ThermoDox®.

Findings from the HEAT Study post-hoc data analysis suggest that ThermoDox® may substantially improve overall survival, when compared to the control
group, in patients if their lesions undergo a 45-minute RFA procedure standardized for a lesion greater than 3 cm in diameter. Data from nine OS sweeps
have been conducted since the top line PFS data from the HEAT Study were announced in January 2013, with each data set demonstrating progressive
improvement in clinical benefit and statistical significance. On August 15, 2016, the Company announced the most recent post-hoc OS analysis from the
HEAT Study. These results demonstrated that in a large, well bounded subgroup of patients with a single lesion (n=285, 41% of the HEAT Study patients),
the combination of ThermoDox® and optimized RFA provided an average 54% risk improvement in OS compared to optimized RFA alone. The Hazard
Ratio  at  this  latest  OS  analysis  is  0.65  (95%  CI  0.45  -  0.94)  with  a  p-value  of  0.02.  Median  OS  for  the  ThermoDox®  group  has  been  reached  which
translates into a two-year survival benefit over the optimized RFA group (projected to be greater than 80 months for the ThermoDox® plus optimized RFA
group  compared  to  less  than  60  months  projection  for  the  optimized  RFA  only  group). These  data  continue  to  strongly  suggest  that  ThermoDox®  may
significantly improve Overall Survival compared to an RFA control in patients whose lesions undergo optimized RFA treatment for 45 minutes or more as
well as support the protocol for our Phase III OPTIMA Study as described below.

Findings  from  the  HEAT  Study  post-hoc  data  analysis  have  shown  to  be  well  balanced  and  not  diminished  in  anyway  by  other  factors.  Supplementary
computational modeling and prospective preclinical animal studies have shown additional support the relationship between heating duration and clinical
outcomes. These data have been presented, without objection, at multiple scientific and medical conferences in 2013 through 2016 by key HEAT Study
investigators and leading liver cancer experts.

On  October  16,  2017,  the  Company  announced  the  publication  of  the  manuscript,  “Phase  III  HEAT  STUDY  Adding  Lyso-Thermosensitive  Liposomal
Doxorubicin to Radiofrequency Ablation in Patients with Unresectable Hepatocellular Carcinoma Lesions,” in Clinical Cancer Research, a peer-reviewed
medical  journal.  The  article  reports  on  one  of  the  largest  controlled  studies  in  hepatocellular  carcinoma.  It  provides  a  comprehensive  review  of
ThermoDox® for the treatment of primary liver cancer. The article details learnings from the Company’s 701 patient HEAT Study and includes results from
computer  simulation  studies  and  includes  findings  from  a  post  hoc  subgroup  analysis,  all  of  which  are  consistent  with  each  other  and  which  -  when
examined together - suggests a clearer understanding of a key ThermoDox® heat-based mechanism of action: the longer the target tissue is heated, the
greater the doxorubicin tissue concentration. Additionally, the article explores a new hypothesis prompted by these findings: ThermoDox® when used in
combination with Radiofrequency Ablation (RFA) standardized to a minimum dwell time of 45 minutes (sRFA > 45 minutes), may increase the overall
survival  (OS)  of  patients  with  HCC.  The  lead  author  is  Won  Young  Tak,  M.D.,  Ph.D.,  Professor  Internal  Medicine,  Gastroenterology  &  Hepatology,
Kyungpook National University Hospital Daegu, Republic of Korea, and there are 22 HEAT Study co-authors along with Nicholas Borys, M.D., Celsion’s
senior vice president and chief medical officer.

IMMUNO-ONCOLOGY Program

On June 20, 2014, we completed the acquisition of substantially all of the assets of EGEN, a private company located in Huntsville, Alabama. Pursuant to
the  Asset  Purchase  Agreement,  CLSN  Laboratories  acquired  all  of  EGEN’s  right,  title  and  interest  in  and  to  substantially  all  of  the  assets  of  EGEN,
including  cash  and  cash  equivalents,  patents,  trademarks  and  other  intellectual  property  rights,  clinical  data,  certain  contracts,  licenses  and  permits,
equipment,  furniture,  office  equipment,  furnishings,  supplies  and  other  tangible  personal  property.  A  key  asset  acquired  from  EGEN  was  the  TheraPlas
Technology Platform and the first drug developed from it is GEN-1.

THERAPLAS Technology Platform

TheraPlas  is  a  technology  platform  for  the  delivery  of  DNA  and  mRNA  therapeutics  via  synthetic  non-viral  carriers  and  is  capable  of  providing  cell
transfection for double-stranded DNA plasmids and large therapeutic RNA segments such as mRNA. There are two components of the TheraPlas system, a
plasmid DNA or mRNA payload encoding a therapeutic protein, and a delivery system. The delivery system is designed to protect the DNA/RNA from
degradation  and  promote  trafficking  into  cells  and  through  intracellular  compartments.  We  designed  the  delivery  system  of  TheraPlas  by  chemically
modifying  the  low  molecular  weight  polymer  to  improve  its  gene  transfer  activity  without  increasing  toxicity.  We  believe  that  TheraPlas  is  a  viable
alternative  to  current  approaches  to  gene  delivery  due  to  several  distinguishing  characteristics,  including  enhanced  molecular  versatility  that  allows  for
complex modifications to improve activity and safety.

The design of TheraPlas delivery system is based on molecular functionalization of polyethyleneimine (PEI), a cationic delivery polymer with a distinct
ability  to  escape  from  the  endosomes  due  to  heavy  protonation.  The  transfection  activity  and  toxicity  of  PEI  is  tightly  coupled  to  its  molecular  weight
therefore the clinical application of PEI is limited. We have used molecular functionalization strategies to improve the activity of low molecular weight
PEIs  without  augmenting  their  cytotoxicity.  In  one  instance,  chemical  conjugation  of  a  low  molecular  weight  branched  BPEI1800  with  cholesterol  and
polyethylene glycol (PEG) to form PEG-PEI-Cholesterol (PPC) dramatically improved the transfection activity of BPEI1800 following in vivo delivery.
Together, the cholesterol and PEG modifications produced approximately 20-fold enhancement in transfection activity. Biodistribution studies following
intraperitoneal or subcutaneous administration of DNA/PPC nanocomplexes showed DNA delivery localized primarily at the injection site with only small
amount escaping into systemic circulation. PPC is the delivery component of our lead TheraPlas product, GEN-1, which is in clinical development for the
treatment ovarian cancer and in preclinical development for the treatment of glioblastoma. The PPC manufacturing process has been scaled up from bench
scale (1-2 g) to 0.6Kg, and several cGMP lots have been produced with reproducible quality.

TheraPlas has emerged as a viable alternative to current approaches due to several distinguishing characteristics such as strong molecular versatility that
allows for complex modifications to improve activity and safety with little difficulty. The biocompatibility of these polymers reduces the risk of adverse
immune response, thus allowing for repeated administration. Compared to naked DNA or cationic lipids, TheraPlas is generally safer, more efficient, and
cost effective. We believe that these advantages place Celsion in strong position to capitalize on this technology.

GEN-1

GEN-1  is  a  DNA-based  immunotherapeutic  product  for  the  localized  treatment  of  ovarian  and  brain  cancers  by  intraperitoneally  administering  an
Interleukin-12 (“IL-12”) plasmid formulated with our proprietary TheraPlas delivery system. In this DNA-based approach, the immunotherapy is combined
with a standard chemotherapy drug, which can potentially achieve better clinical outcomes than with chemotherapy alone. We believe that increases in IL-
12 concentrations at tumor sites for several days after a single administration could create a potent immune environment against tumor activity and that a
direct  killing  of  the  tumor  with  concomitant  use  of  cytotoxic  chemotherapy  could  result  in  a  more  robust  and  durable  antitumor  response  than
chemotherapy alone. We believe the rationale for local therapy with GEN-1 are based on the following:

● Loco-regional  production  of  the  potent  cytokine  IL-12  avoids  toxicities  and  poor  pharmacokinetics  associated  with  systemic  delivery  of

recombinant IL-12;

● Persistent local delivery of IL-12 lasts up to one week and dosing can be repeated;

● Ideal for long-term maintenance therapy.

Ovarian Cancer Overview

Ovarian cancer is the most lethal of gynecological malignancies among women with an overall five-year survival rate of 45%. This poor outcome is due in
part to the lack of effective prevention and early detection strategies. There were approximately 22,000 new cases of ovarian cancer in the U.S. in 2014
with an estimated 14,000 deaths. Mortality rates for ovarian cancer declined very little in the last forty years due to the unavailability of detection tests and
improved  treatments.  Most  women  with  ovarian  cancer  are  not  diagnosed  until  Stages  III  or  IV,  when  the  disease  has  spread  outside  the  pelvis  to  the
abdomen  and  areas  beyond  causing  swelling  and  pain,  where  the  five-year  survival  rates  are  25  -  41  percent  and  11  percent,  respectively.  First-line
chemotherapy regimens are typically platinum-based combination therapies. Although this first line of treatment has an approximate 80 percent response
rate, 55 to 75 percent of women will develop recurrent ovarian cancer within two years and ultimately will not respond to platinum therapy. Patients whose
cancer recurs or progresses after initially responding to surgery and first-line chemotherapy have been divided into one of the two groups based on the time
from completion of platinum therapy to disease recurrence or progression. This time period is referred to as platinum-free interval. The platinum-sensitive
group  has  a  platinum-free  interval  of  longer  than  six  months.  This  group  generally  responds  to  additional  treatment  with  platinum-based  therapies.  The
platinum-resistant  group  has  a  platinum-free  interval  of  shorter  than  six  months  and  is  resistant  to  additional  platinum-based  treatments.  Pegylated
liposomal doxorubicin, topotecan, and Avastin are the only approved second-line therapies for platinum-resistant ovarian cancer. The overall response rate
for these therapies is 10 to 20 percent with median overall survival of eleven to twelve months. Immunotherapy is an attractive novel approach for the
treatment  of  ovarian  cancer  particularly  since  ovarian  cancers  are  considered  immunogenic  tumors.  IL-12  is  one  of  the  most  active  cytokines  for  the
induction  of  potent  anti-cancer  immunity  acting  through  the  induction  of  T-lymphocyte  and  natural  killer  cell  proliferation.  The  precedence  for  a
therapeutic role of IL-12 in ovarian cancer is based on epidemiologic and preclinical data.

GEN-I OVATION Study. In February 2015, we announced that the FDA accepted, without objection, the Phase I dose-escalation clinical trial of GEN-1 in
combination with the standard of care in neoadjuvant ovarian cancer (the “OVATION Study”). On September 30, 2015, we announced enrollment of the
first patient in the OVATION Study. The OVATION Study was designed to (i) identify a safe, tolerable and potentially therapeutically active dose of GEN-
1 by recruiting and maximizing an immune response; (ii) to enroll three to six patients per dose level and will evaluate safety and efficacy and (iii) attempt
to define an optimal dose for a follow-on Phase I/II study. In addition, the OVATION Study establishes a unique opportunity to assess how cytokine-based
compounds such as GEN-1, directly affect ovarian cancer cells and the tumor microenvironment in newly diagnosed patients. The study was designed to
characterize the nature of the immune response triggered by GEN-1 at various levels of the patients’ immune system, including:

● Infiltration  of  cancer  fighting  T-cell  lymphocytes  into  primary  tumor  and  tumor  microenvironment  including  peritoneal  cavity,  which  is  the

primary site of metastasis of ovarian cancer;

● Changes in local and systemic levels of immuno-stimulatory and immunosuppressive cytokines associated with tumor suppression and growth,

respectively; and

● Expression profile of a comprehensive panel of immune related genes in pre-treatment and GEN-1-treated tumor tissue.

We initiated the OVATION Study at four clinical sites at the University of Alabama at Birmingham, Oklahoma University Medical Center, Washington
University in St. Louis and the Medical College of Wisconsin. During 2016 and 2017, we announced data from the first fourteen patients in the OVATION
Study, who completed treatment. On October 3, 2017, we announced final clinical and translational research data from the OVATION Study.

Key translational research findings from all evaluable patients are consistent with the earlier reports from partial analysis of the data and are summarized
below:

● The  intraperitoneal  treatment  of  GEN-1  in  conjunction  with  neoadjuvant  chemotherapy  resulted  in  dose  dependent  increases  in  IL-12  and
Interferon-gamma (IFN-γ) levels that were predominantly in the peritoneal fluid compartment with little to no changes observed in the patients’
systemic circulation. These and other post-treatment changes including decreases in VEGF levels in peritoneal fluid are consistent with an IL-12
based immune mechanism;

51

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● Consistent  with  the  previous  partial  reports,  the  effects  observed  in  the  IHC  analysis  were  pronounced  decreases  in  the  density  of

immunosuppressive T-cell signals (Foxp3, PD-1, PDL-1, IDO-1) and increases in CD8+ cells in the tumor microenvironment;

● The ratio  of  CD8+  cells  to  immunosuppressive  cells  was  increased  in  approximately  75%  of  patients  suggesting  an  overall  shift  in  the  tumor
microenvironment  from  immunosuppressive  to  pro-immune  stimulatory  following  treatment  with  GEN-1.  An  increase  in  CD8+  to
immunosuppressive T-cell populations is a leading indicator and believed to be a good predictor of improved overall survival; and

● Analysis of peritoneal fluid by cell sorting, not reported before, shows a treatment-related decrease in the percentage of immunosuppressive T-cell
(Foxp3+), which is consistent with the reduction of Foxp3+ T-cells in the primary tumor tissue, and a shift in tumor naïve CD8+ cell population to
more efficient tumor killing memory effector CD8+ cells.

The Company also reported positive clinical data from the first fourteen patients who completed treatment in the OVATION Study. GEN-1 plus standard
chemotherapy produced positive clinical results, with no dose limiting toxicities and positive dose dependent efficacy signals which correlate well with
positive surgical outcomes as summarized below:

● Of the fourteen patients treated in the entire study, two patients demonstrated a complete response, ten patients demonstrated a partial response
and two patients demonstrated stable disease, as measured by RECIST criteria. This translates to a 100% disease control rate and an 86% objective
response rate (“ORR”). Of the five patients treated in the highest dose cohort, there was a 100% ORR with one complete response and four partial
responses;

● Fourteen patients had successful resections of their tumors, with nine patients (64%) having a complete tumor resection (“R0”), which indicates a
microscopically margin-negative resection in which no gross or microscopic tumor remains in the tumor bed. Seven out of eight (88%) patients in
the highest two dose cohorts experienced a R0 surgical resection. All five patients treated at the highest dose cohort experienced a R0 surgical
resection;

● All patients  experienced  a  clinically  significant  decrease  in  their  CA-125  protein  levels  as  of  their  most  recent  study  visit.  CA-125  is  used  to
monitor certain cancers during and after treatment. CA-125 is present in greater concentrations in ovarian cancer cells than in other cells; and

On March 2, 2019, the Company announced final PFS results from the OVATION Study. Median progression-free survival (PFS) in patients treated per
protocol (n=14) was 21 months and was 17.1 months for the intent-to-treat population (n=18) for all dose cohorts, including three patients who dropped out
of the study after 13 days or less, and two patients who did not receive full NAC and GEN-1 cycles. Under the current standard of care, in women with
Stage III/IV ovarian cancer undergoing NAC, the disease progresses within about 12 months on average. The results from the OVATION Study support
continued evaluation of GEN-1 based on promising tumor response, as reported in the PFS data, and the ability for surgeons to completely remove visible
tumor at debulking surgery. GEN-1 was well tolerated and no dose-limiting toxicities were detected. Intraperitoneal administration of GEN-1 was feasible
with broad patient acceptance.

GEN-1 OVATION 2 Study. The Company held an Advisory Board Meeting on September 27, 2017 with the clinical investigators and scientific experts
including  those  from  Roswell  Park  Cancer  Institute,  Vanderbilt  University  Medical  School,  and  M.D.  Anderson  Cancer  Center  to  review  and  finalize
clinical,  translational  research  and  safety  data  from  the  Phase  IB  OVATION  Study  in  order  to  determine  the  next  steps  forward  for  our  GEN-1
immunotherapy program.

On November 13, 2017, the Company filed its Phase I/II clinical trial protocol with the U.S. Food and Drug Administration for GEN-1 for the localized
treatment of ovarian cancer. The protocol is designed with a single dose escalation phase to 100 mg/m² to identify a safe and tolerable dose of GEN-1 while
maximizing an immune response. The Phase I portion of the study will be followed by a continuation at the selected dose in 130 patients randomized Phase
II study. On November 5, 2019, the Company announced that the independent Data Safety Monitoring Board (DSMB) completed its safety review of data
from  the  first  eight  patients  enrolled  in  the  ongoing  Phase  I/II  OVATION  2  Study.  Based  on  the  DSMB’s  recommendation,  the  study  will  continue  as
planned and the Company will proceed with completing enrollment in the Phase I portion of the trial.

In  the  OVATION  2  Study,  patients  in  the  GEN-1  treatment  arm  will  receive  GEN-1  plus  chemotherapy  pre-  and  post-interval  debulking  surgery.  The
OVATION 2 Study will include up to 130 patients with Stage III/IV ovarian cancer, with 12 to 15 patients in the Phase I portion and up to 118 patients in
Phase  II.  The  study  is  powered  to  show  a  33%  improvement  in  the  primary  endpoint,  PFS,  when  comparing  GEN-1  with  neoadjuvant  +  adjuvant
chemotherapy versus neoadjuvant + adjuvant chemotherapy alone. The PFS primary analysis will be conducted after at least 80 events have been observed
or after all patients have been followed for at least 16 months, whichever is later.

Developed  with  extensive  input  from  the  Company’s  Medical  Advisory  Board,  the  OVATION  2  Study  builds  on  promising  clinical  and  translational
research data from the Phase IB dose-escalation OVATION I Study, in which enrolled patients received escalating weekly doses of GEN-1 up to 79 mg/m²
for a total of eight treatments in combination with NACT, followed by IDS. In addition to exploring a higher dose of GEN-1 in the OVATION 2 study,
patients will continue to receive GEN-1 after their IDS in combination with adjuvant chemotherapy.

The latest DSMB review of GEN-1 at 100 mg/m² has confirmed that there were no dose limiting toxicities detected in any of the five patients dosed with
GEN-1 and that intraperitoneal administration is well tolerated even when given with standard NACT. Of the eight patients treated in the Phase I portion of
the OVATION 2 Study, five patients were treated with GEN-1 plus NACT and three patients were treated with NACT only.

In March 2020, the Company announced highly encouraging initial clinical data from the first 15 patients enrolled in the ongoing Phase I/II OVATION 2
Study for patients newly diagnosed with Stage III and IV ovarian cancer. The OVATION 2 Study combines GEN-1, the Company’s IL-12 gene-mediated
immunotherapy, with standard-of-care neoadjuvant chemotherapy (NACT). Following NACT, patients undergo interval debulking surgery (IDS), followed
by three additional cycles of chemotherapy.

GEN-1  plus  standard  NACT  produced  positive  dose-dependent  efficacy  results,  with  no  dose-limiting  toxicities,  which  correlates  well  with  successful
surgical outcomes as summarized below:

● Of the 15 patients treated in the Phase I portion of the OVATION 2 Study, nine patients were treated with GEN-1 at a dose of 100 mg/m² plus
NACT and six patients were treated with NACT only. All 15 patients had successful resections of their tumors, with seven out of nine patients
(78%)  in  the  GEN-1  treatment  arm  having  an  R0  resection,  which  indicates  a  microscopically  margin-negative  resection  in  which  no  gross  or
microscopic tumor remains in the tumor bed. Only three out of six patients (50%) in the NACT only treatment arm had a R0 resection.

● When combining these results with the surgical resection rates observed in the Company’s prior Phase Ib dose-escalation trial (the OVATION 1
Study), a population of patients with inclusion criteria identical to the OVATION 2 Study, the data reflect the strong dose-dependent efficacy of
adding GEN-1 to the current standard of care NACT:

0, 36, 47 mg/m² of GEN-1 plus NACT
61, 79, 100 mg/m² of GEN-1 plus NACT

% of Patients with 
R0 Resections

42%
82%

n=12
n=17

● The objective response rate (ORR) as measured by Response Evaluation Criteria in Solid Tumors (RECIST) criteria for the 0, 36, 47 mg/m² dose
GEN-1  patients  were  comparable,  as  expected,  to  the  higher  (61,  79,  100  mg/m²)  dose  GEN-1  patients,  with  both  groups  demonstrating  an
approximate 80% ORR.

Acquisition of EGEN Assets

On June 20, 2014, we completed the acquisition of substantially all of the assets of EGEN, which has changed its company name to EGWU, Inc. after the
closing of the acquisition, pursuant to an asset purchase agreement (the “Asset Purchase Agreement”) dated as of June 6, 2014, by and between EGEN and
Celsion. We acquired all of EGEN’s right, title and interest in and to substantially all of the assets of EGEN, including cash and cash equivalents, patents,
trademarks and other intellectual property rights, clinical data, certain contracts, licenses and permits, equipment, furniture, office equipment, furnishings,
supplies and other tangible personal property. In addition, CLSN Laboratories assumed certain specified liabilities of EGEN, including the liabilities arising
out  of  the  acquired  contracts  and  other  assets  relating  to  periods  after  the  closing  date.  The  total  purchase  price  for  the  asset  acquisition  is  up  to  $44.4
million, including potential future earnout payments of up to $30.4 million contingent upon achievement of certain earnout milestones set forth in the Asset
Purchase Agreement. At the closing, we paid approximately $3.0 million in cash after the expense adjustment and issued 193,728 shares of our common
stock to EGEN. The shares of common stock were issued in a private transaction exempt from registration under the Securities Act, pursuant to Section
4(2) thereof. In addition, the Company issued the Holdback Shares on June 16, 2017. On March 28, 2019, the Company and EGWU, Inc, entered into the
Amended  Asset  Purchase  Agreement.  Pursuant  to  the  Amended  Asset  Purchase  Agreement,  payment  of  the  earnout  milestone  liability  related  to  the
Ovarian Cancer Indication of $12.4 million has been modified. The Company has the option to make the payment as follows:

$7.0 million in cash within 10 business days of achieving the milestone; or

a)
b) $12.4 million in cash, common stock of the Company, or a combination of either, within one year of achieving the milestone.

The Company provided EGWU, Inc. 200,000 warrants to purchase common stock at a strike price of $0.01 per warrant share as consideration for entering
into this amended agreement. The warrant shares have no expiration and were fair valued at $2.00 using the closing price of a share of Celsion stock on the
date of issuance offset by the exercise price and recorded as a non-cash expense in the income statement and were classified as equity on the balance sheet.

Our obligations to make the earnout payments will terminate on the eight anniversary of the closing date. In the acquisition, we purchased GEN-1, a DNA-
based immunotherapy for the localized treatment of ovarian and brain cancers, and two platform technologies for the development of treatments for those
suffering  with  difficult-to-treat  forms  of  cancer,  novel  nucleic  acid-based  immunotherapies  and  other  anti-cancer  DNA  or  RNA  therapies,  including
TheraPlas and TheraSilence.

Acquired in-process research and development (“IPR&D”) consists of EGEN’s drug technology platforms: TheraPlas and TheraSilence. The fair value of
the IPR&D drug technology platforms was estimated to be $24.2 million as of the acquisition date. As of the closing of the acquisition, the IPR&D was
considered indefinite lived intangible assets and will not be amortized. IPR&D is reviewed for impairment at least annually as of our third quarter ended
September 30, and whenever events or changes in circumstances indicate that the carrying value of the assets might not be recoverable. On December 31,
2016, the Company determined one of its IPR&D assets related to its RNA delivery system was impaired and wrote off its fair value, incurring a non-cash
charge of $1.4 million during 2016. During its annual assessments on September 30, 2017 and 2018, the Company determined its IPR&D asset related to
its glioblastoma multiforme cancer (GBM) product candidate, originally fair valued at $9.4 million on the date of acquisition, was impaired and wrote this
asset’s carrying value down to $2.4 million collectively after those two assessments, incurring non-cash charges of $2.5 million and $4.5 million during
2017 and 2018, respectively. On September 30, 2019, the Company evaluated its IPR&D of the (GBM) product candidate and concluded that it is not more
likely than not that the asset is further impaired. On September 30, 2019 and 2018, the Company evaluated its IPR&D of the ovarian cancer indication and
concluded that it is not more likely than not that the asset is impaired. As no other indicators of impairment existed during the fourth quarter of 2019, the
Company concluded none of the other IPR&D assets were impaired at December 31, 2019. The carrying amount of the ovarian cancer indication was $13.3
million at December 31, 2019 and 2018.

Covenant Not to Compete (CNTC)

Pursuant to the EGEN Purchase Agreement, EGEN provided certain covenants (“Covenant Not To Compete”) to the Company whereby EGEN agreed,
during  the  period  ending  on  the  seventh  anniversary  of  the  closing  date  of  the  acquisition  on  June  20,  2014,  not  to  enter  into  any  business,  directly  or
indirectly, which competes with the business of the Company nor will it contact, solicit or approach any of the employees of the Company for purposes of
offering employment.

Business Plan

As a clinical stage biopharmaceutical company, our business and our ability to execute our strategy to achieve our corporate goals are subject to numerous
risks and uncertainties. Material risks and uncertainties relating to our business and our industry are described in “Part I, Item 1A. Risk Factors” in this
Annual Report on Form 10-K.

We had $16.7 million in cash, investments, interest receivable and deferred income tax asset as of December 31, 2019, as well as $6.4 million we have
raised thus far in 2020 under the 2019 Aspire Purchase Agreement and from the February 2020 Offering. The Company has approximately $15 million
available under the Capital on Demand Agreement with JonesTrading International Services LLC. Given our development plans, we anticipate our current
cash resources will be sufficient to fund our operations and financial commitments through mid-2021. On March 5, 2020, we terminated the 2019 Aspire
Purchase Agreement. Other than the Capital on Demand Agreement with Jones Trading that provides us the ability to sell equity securities in the future, we
have no other committed sources of additional capital and there is uncertainty whether additional funding will be available when needed on terms that will
be acceptable to it, or at all. If the Company would not be able to obtain financing when needed, it could be unable to carry out the business plan and may
have to significantly limit its operations and its business and its financial condition and results of operations could be materially harmed. The extent to
which the recent global Covid-19 pandemic impacts our business will depend on future developments, which are highly uncertain and cannot be predicted,
including  new  information  that  may  emerge  concerning  the  severity  of  COVID-19  and  the  actions  to  contain  or  treat  its  impact,  among  others.  Any
significant  infectious  disease  outbreak,  including  the  COVID-19  pandemic,  could  result  in  a  widespread  health  crisis  that  could  adversely  affect  the
economies  and  financial  markets  worldwide,  resulting  in  an  economic  downturn  that  could  impact  our  business,  financial  condition  and  results  of
operations, including our ability to obtain additional funding, if needed.

Financing Overview

Equity, Debt and Other Forms of Financing

As more fully discussed in Note 9 of the Financial Statement included in this Annual Report, during the fourth quarter of 2018, the Company received
eligibility from the New Jersey Economic Development Authority to sell, and did sell, $11.1 million of its unused New Jersey net operating losses under
the Technology Business Tax Certificate Program, receiving $10.4 million of non-dilutive funding in the process. During the fourth quarter of 2019, the
Company received approval from the New Jersey Economic Development Authority to sell $1.9 million its New Jersey net operating losses. In early 2020,
the Company entered into an agreement to sell these net operating losses and expects to receive net proceeds of approximately $1.8 million in the second
quarter of 2020.

During 2018 and 2019, we issued a total of 5.1 million shares of common stock as discussed below for an aggregate $9.4 million in gross proceeds. During
the  first  quarter  of  2020,  the  Company  has  issued  a  total  of  5.6  million  shares  of  common  stock  for  an  aggregate  of  $6.4  million  in  gross  proceeds  as
discussed in more detail below. In June 2018, we entered a $10 million loan facility with Horizon Technology Finance Corporation (“Horizon”).

● On June 27, 2018, the Company entered into the Horizon Credit Agreement with Horizon that provided $10 million in new capital. The Company
drew down $10 million upon closing of the Horizon Credit Agreement on June 27, 2018. The Company anticipates that it will use the funding
provided under the Horizon Credit Agreement for working capital and advancement of its product pipeline. The obligations under the Horizon
Credit Agreement are secured by a first-priority security interest in substantially all assets of Celsion other than intellectual property assets. The
obligations will bear interest at a rate calculated based on one-month LIBOR plus 7.625%. Payments under the loan agreement are interest only
for  the  first  twenty-four  (24)  months  after  loan  closing,  followed  by  a  24-month  amortization  period  of  principal  and  interest  through  the
scheduled maturity date.

● On August 31, 2018, the Company entered into the 2018 Aspire Purchase Agreement with Aspire Capital Fund LLC (“Aspire Capital”) which
provides  that,  upon  the  terms  and  subject  to  the  conditions  and  limitations  set  forth  therein,  Aspire  Capital  is  committed  to  purchase  up  to  an
aggregate  of  $15.0  million  of  shares  of  the  Company’s  common  stock  over  the  24-month  term  of  the  2018  Aspire  Purchase  Agreement.  On
October 12, 2018, the Company filed with the SEC a prospectus supplement to the 2018 Shelf Registration Statement registering all of the shares
of common stock that may be offered to Aspire Capital from time to time. The timing and amount of sales of the Company’s common stock to
Aspire Capital. Aspire Capital has no right to require any sales by the Company but is obligated to make purchases from the Company as directed
by  the  Company  in  accordance  with  the  Purchase  Agreement.  There  are  no  limitations  on  use  of  proceeds,  financial  or  business  covenants,
restrictions  on  future  funding,  rights  of  first  refusal,  participation  rights,  penalties  or  liquidated  damages  in  the  Purchase  Agreement.  In
consideration  for  entering  into  the  Purchase  Agreement,  concurrently  with  the  execution  of  the  Purchase  Agreement,  the  Company  issued  to
Aspire  Capital  164,835  Commitment  Shares.  The  2018  Aspire  Purchase  Agreement  may  be  terminated  by  the  Company  at  any  time,  at  its
discretion, without any cost to the Company. During 2018 and 2019 the Company sold and issued an aggregate of 3.4 million shares under the
Purchase Agreement, receiving approximately $6.5 million. All proceeds from the Company received under the 2018 Aspire Purchase Agreement
were  used  for  working  capital  and  general  corporate  purposes.   As  a  result  of  the  Company  and  Aspire  Capital  entering  into  a  new  purchase
agreement on October 28, 2019 discussed in the next paragraph, the 2018 Aspire Purchase Agreement was terminated.

● On October 28, 2019, Company, entered into the 2019 Aspire Purchase Agreement with Aspire Capital. The terms and conditions pursuant to the
2019 Aspire Purchase Agreement are substantially similar to the 2018 Aspire Purchase Agreement. Pursuant to the new 2019  Aspire  Purchase
Agreement, Aspire Capital is committed to purchase up to an aggregate of $10.0 million of shares of the Company’s common stock over the 24-
month term of the 2019 Aspire Purchase Agreement. Concurrently with entering into the 2019 Aspire Purchase Agreement, the Company also
entered into a registration rights agreement with Aspire Capital (the “Registration Rights Agreement”), in which the Company agreed to file one
or  more  registration  statements,  as  permissible  and  necessary  to  register  under  the  Securities  Act  of  1933,  as  amended  (the  “Securities  Act”),
registering the  sale  of  the  shares  of  the  Company’s  common  stock  that  have  been  and  may  be  issued  to  Aspire  Capital  under  the  2019  Aspire
Purchase Agreement. In consideration for entering into the 2019 Aspire Purchase Agreement, the Company issued to Aspire Capital an additional
100,000 Commitment Shares. On November 8, 2019, the Company filed with the SEC a Registration Statement on Form S-1 registering all the
shares of common stock that may be offered to Aspire Capital from time to time under the 2019 Aspire Purchase Agreement.  During 2019, the
Company sold 0.5 million shares of common stock under the 2019 Aspire Purchase Agreement, receiving approximately $0.7 million in gross
proceeds.  On March 5, 2020, the Company delivered notice to Aspire Capital terminating the 2019 Aspire Purchase Agreement effective as of
March  6,  2020.    During  the  first  quarter  of  2020,  the  Company  sold  1.0  million  shares  of  common  stock  under  the  2019  Aspire  Purchase
Agreement and received $1.6 million in gross proceeds.

55

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● We were a party to a Controlled Equity OfferingSM Sales Agreement (ATM) dated as of February 1, 2013 with Cantor Fitzgerald & Co., pursuant
to  which  we  may  sell  additional  shares  of  our  common  stock  having  an  aggregate  offering  price  of  up  to  $25  million  through  “at-the-market”
equity offerings from time to time. During 2018, the Company sold 0.5 million shares of common stock under the ATM, receiving approximately
$1.2 million in net proceeds. On October 10, 2018, the Company delivered notice to Cantor terminating the ATM effective as of October 20, 2018.
From  February  2013  through  the  date  of  termination,  the  Company  sold  1.8  million  shares  of  Common  Stock  under  the  Sales  Agreement
generating gross proceeds of $12.8 million. The Company has no further obligations under the ATM.

● On December  4,  2018,  the  Company  entered  into  a  new  Capital  on  DemandTM  Sales  Agreement  (the  “Capital  on  Demand  Agreement”)  with
JonesTrading Institutional Services LLC, as sales agent (“JonesTrading”), pursuant to which the Company may offer and sell, from time to time,
through JonesTrading shares of common stock having an aggregate offering price  of  up  to  $16.0  million.  The  Company  intends  to  use  the  net
proceeds from the offering, if any, for general corporate purposes, including research and development activities, capital expenditures and working
capital.  The  Company  is  not  obligated  to  sell  any  Common  Stock  under  the  Capital  on  Demand  Agreement  and,  subject  to  the  terms  and
conditions of the Capital on Demand Agreement, JonesTrading will use commercially reasonable efforts, consistent with its normal trading and
sales practices and applicable state and federal law, rules and regulations and the rules of The Nasdaq Capital Market, to sell common stock from
time to time based upon Celsion’s instructions, including any price, time or size limits or other customary parameters or conditions the Company
may  impose.  Under  the  Capital  on  Demand  Agreement,  JonesTrading  may  sell  common  stock  by  any  method  deemed to be an “at the market
offering” as defined in Rule 415 promulgated under the Securities Act of 1933, as amended. The Capital on Demand Agreement will terminate
upon the earlier of (i) the sale of all shares of our common stock subject to the Sales Agreement, and (ii) the termination of the Capital on Demand
Agreement by JonesTrading or Celsion. The Capital on Demand Agreement may be terminated by JonesTrading or the Company at any time upon
10 days’ notice to the other party, or by JonesTrading at any time in certain circumstances, including the occurrence of a material adverse change
in the Company. The Company did not sell any shares under the Capital on Demand Agreement during 2018.  During 2019, the Company sold 0.5
million shares of common stock under the Capital on Demand Agreement, receiving approximately $1.0 million.   

● On February 27, 2020, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with several institutional investors, pursuant
to  which  we  agreed  to  issue  and  sell,  in  a  registered  direct  offering  (the  “February  2020  Offering”),  an  aggregate  of  4,571,428  shares  (the
“Shares”) of our common stock at an offering price of $1.05 per share for gross proceeds of approximately $4.8 million before the deduction of
the Placement Agent fees and offering expenses. The Shares were offered by the Company pursuant to a registration statement on Form S-3 (File
No.  333-227236).    The  Purchase  Agreement  contains  customary  representations,  warranties  and  agreements  by  the  Company  and  customary
conditions to closing.  In a concurrent private placement (the “Private Placement”), the Company agreed to issue to the investors that participated
in the Offering, for no additional consideration, warrants, to purchase up to 2,971,428 shares of Common Stock (the “Original Warrants”). The
Original Warrants were initially exercisable six months following their and were set to expire on the five-year anniversary of such initial exercise
date. The Warrants had an exercise price of $1.15 per share subject to adjustment as provided therein.  On March 12, 2020 the Company entered
into private exchange agreements (the “Exchange Agreements”) with holders the Warrants. Pursuant to the Exchange Agreements, in return for a
higher exercise price of $1.24 per share of Common Stock, the Company issued new warrants to the Investors to purchase up to 3,200,000 shares
of  Common  Stock  (the  “Exchange  Warrants”)  in  exchange  for  the  Original  Warrants.  The  Exchange  Warrants,  like  the  Original  Warrants, are
initially  exercisable  six  months  following  their  issuance  (the  “Initial  Exercise  Date”)  and  expire  on  the  five-year  anniversary  of  their  Initial
Exercise Date. Other than having a higher exercise price, different issue date, Initial Exercise Date and expiration date, the terms of the Exchange
Warrants are identical to those of the Original Warrants.

Please refer to Note 2 of the Financial Statements contained in this Form 10-K. Also refer to Item IA, Risk Factors, including, but not limited to, “We will
need to raise substantial additional capital to fund our planned future operations, and we may be unable to secure such capital without dilutive financing
transactions. If we are not able to raise additional capital, we may not be able to complete the development, testing and commercialization of our product
candidates.”

Critical Accounting Policies and Estimates

Our financial statements, which appear at Item 8 to this Annual Report, have been prepared in accordance with accounting principles generally accepted in
the U.S., which require that we make certain assumptions and estimates and, in connection therewith, adopt certain accounting policies. Our significant
accounting policies are set forth in Note 1 to our financial statements. Of those policies, we believe that the policies discussed below may involve a higher
degree of judgment and may be more critical to an accurate reflection of our financial condition and results of operations.

Revenue Recognition

In  May  2014,  the  FASB  issued  Accounting  Standards  Update  (ASU)  No.  2014-09  “Revenue  from  Contracts  with  Customers  (Topic  606),”  which
supersedes all existing revenue recognition requirements, including most industry-specific guidance. The new standard requires a company to recognize
revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or
services. ASU 2014 - 09 was originally going to be effective on January 1, 2017; however, the FASB issued ASU 2015-14, “Revenue from Contracts with
Customers (Topic 606) - Deferral of the Effective Date,” which deferred the effective date of ASU 2014-09 by one year to January 1, 2018. In March 2016,
the FASB issued ASU No. 2016 - 8, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations. The amendments in this
ASU do not change the core principle of ASU No. 2014 - 09 but the amendments clarify the implementation guidance on reporting revenue gross versus
net. The effective date for the amendments in this ASU is the same as the effective date of ASU No. 2014-09. In April 2016, the FASB issued ASU No.
2016-10,  “Revenue  from  Contracts  with  Customers  (Identifying  Performance  Obligations  and  Licensing),”  to  clarify  the  implementation  guidance  on
identifying  performance  obligations  and  licensing  (collectively  “the  new  revenue  standards”).  The  new  revenue  standards  allow  for  either  “full
retrospective” adoption, meaning the standard is applied to all periods presented, or “modified retrospective” adoption, meaning the standard is applied
only to the most current period presented in the financial statements. The new revenue standard became effective for us on January 1, 2018. Under the new
revenue  standards,  we  recognize  revenue  following  a  five-step  model  prescribed  under  ASU  No.  2014-09;  (i)  identify  contract(s)  with  a  customer;  (ii)
identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in
the contract; and (v) recognize revenues when (or as) we satisfy the performance obligation. As further described in Note 16, the Company currently has
only one contract subject to the new revenue standards. After performance of the five-step model discussed above, the Company concluded the adoption of
the new revenue standards as of January 1, 2018 did not change our revenue recognition policy nor does it have an effect on our financial statements using
either the full retrospective or the modified retrospective adoption methods.

In-Process Research and Development, Other Intangible Assets and Goodwill

During  2014,  the  Company  acquired  certain  assets  of  EGEN,  Inc.  As  more  fully  described  in  Note  5  to  our  Consolidated  Financial  Statements,  the
acquisition was accounted for under the acquisition method of accounting which required the Company to perform an allocation of the purchase price to the
assets  acquired  and  liabilities  assumed.  Under  the  acquisition  method  of  accounting,  the  total  purchase  price  is  allocated  to  net  tangible  and  intangible
assets and liabilities based on their estimated fair values as of the acquisition date.

Lease Accounting

In  February  2016,  the  FASB  issued  Accounting  Standards  Update  No.  2016-02,  “Leases”  -  Topic  842  (ASC  Topic  842),  which  requires  that  lessees
recognize assets and liabilities for leases with lease terms greater than twelve months in the statement of financial position. Leases will be classified as
either finance or operating, with classification affecting the pattern of expense recognition in the income statement. This update also requires improved
disclosures to help users of financial statements better understand the amount, timing and uncertainty of cash flows arising from leases. The update became
effective  for  fiscal  years  beginning  after  December  15,  2018,  including  interim  reporting  periods  within  that  reporting  period.  The  FASB  subsequently
issued the following amendments to ASC Topic 842, which have the same effective date and transition date of January 1, 2019:

● ASU No. 2018-10, Codification Improvements to Topic 842, Leases, which amends certain narrow aspects of the guidance issued in ASU 2016-

02; and

● ASU No.  2018-11,  Leases  (Topic  842):  Targeted  Improvements,  which  allows  for  a  transition  approach  to  initially  apply  ASU  2016-02  at  the
adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption as well as an
additional practical expedient for lessors to not separate non-lease components from the associated lease component.

57

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We adopted Topic ASC 842 effective January 1, 2019 and elected to apply the available practical expedients and implement internal controls to enable the
preparation  of  financial  information  on  adoption.  We  have  identified  all  of  our  leases  which  consist  of  the  New  Jersey  corporate  office  lease  and  the
Alabama lab facility lease and we estimate the adoption of this standard will result in the recognition of right-of-use assets of approximately $1.4 million,
related  operating  lease  liabilities  of  $1.5  million  and  reduced  other  liabilities  by  approximately  $0.1  million  on  the  consolidated  balance  sheets  as  of
January  1,  2019  of  approximately  $1.5  million  related  to  our  operating  lease  commitments,  with  no  material  impact  to  the  opening  balance  of  retained
earnings. See Note 15 for further discussions regarding the adoption of ASC Topic 842.

Statements of Stockholders’ Equity

In August 2018, the SEC issued a final rule to simplify certain disclosure requirements. In addition, the amendments expanded the disclosure requirements
on  the  analysis  of  stockholders’  equity  for  interim  financial  statements.  In  August  and  September  2018,  further  amendments  were  issued  to  provide
implementation  guidance  on  adoption  of  the  SEC  rule  and  transition  guidance  for  the  new  interim  stockholders’  equity  disclosure.  We  adopted  this
amended guidance in the first quarter of 2019. The adoption of this amended guidance resulted in us disclosing the Condensed Consolidated Statements of
Changes in Stockholders’ Equity in each of the quarterly reporting period starting in 2019.

We review our financial reporting and disclosure practices and accounting policies on an ongoing basis to ensure that our financial reporting and disclosure
system  provides  accurate  and  transparent  information  relative  to  the  current  economic  and  business  environment. As  part  of  the  process,  the  Company
reviews the selection, application and communication of critical accounting policies and financial disclosures. The preparation of our financial statements
in  conformity  with  accounting  principles  generally  accepted  in  the  U.S.  requires  that  our  management  make  estimates  and  assumptions  that  affect  the
reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts
of  revenues  and  expenses  during  the  reporting  period.  We  review  our  estimates  and  the  methods  by  which  they  are  determined  on  an  ongoing  basis.
However, actual results could differ from our estimates.

Results of Operations

Comparison of Fiscal Year Ended December 31, 2019 and Fiscal Year Ended December 31, 2018.

For the year ended December 31, 2019, our net loss was $16.9 million compared to a net loss of $11.9 million for the year ended December 31, 2018. The
Company recognized $1.8 million and $10.4 million in tax benefits from the sale of its New Jersey net operating losses under the Technology Business Tax
Certificate Program in the fourth quarters of 2019 and 2018, respectively. With $16.7 million in cash, investments, interest receivable and deferred income
tax  asset  at  December  31,  2019  coupled  with  the  $6.4  million  of  additional  capital  raised  during  the  first  quarter  of  2020,  the  Company  believes  it  has
sufficient capital resources to fund its operations through mid-2021.

Technology Development and Licensing Revenue

In January 2013, we entered into a technology development contract with Hisun, pursuant to which Hisun paid us a non-refundable technology transfer fee
of $5.0 million to support our development of ThermoDox® in the China territory. The $5.0 million received as a non-refundable payment from Hisun in
the  first  quarter  2013  has  been  recorded  to  deferred  revenue  and  will  be  amortized  over  the  ten-year  term  of  the  agreement;  therefore,  we  recognized
revenue of $500,000 in each of the years 2019 and 2018.

Research and Development Expenses

Research and development (“R&D”) expenses increased $1.2 million or 10% from $11.9 million in 2018 to $13.1 million in 2019. Costs associated with
the Phase III OPTIMA Study were $4.1 million in 2019 compared to $4.7 million in 2018. The prior year period was favorably impacted by a $0.8 million
credit resulting from cost concessions negotiated with the Company’s lead contract research organization (CRO) for the OPTIMA Study. Excluding this
one-time credit, clinical development costs for the Phase III OPTIMA Study decreased $1.4 million in 2019, due to the completion of enrollment of the
study in August 2018. The Company continues to follow patients on the study through the two preplanned efficacy analyses and the final efficacy analysis
after 197 OS events. Costs associated with the OVATION 2 Study were $0.6 million in 2019 compared to $0.4 million in 2018. Regulatory costs were $1.1
million in 2019 compared to $0.3 million in 2018. Other clinical costs were $2.5 million in each of 2019 and 2018. Costs associated with the production of
ThermoDox®  were  $1.5  million  during  2019  compared  to  $1.1  million  in  2018  as  the  Company  is  preparing  registration  batches  at  its  three  CMOs
assuming a successful outcome of the OPTIMA Study. R&D costs associated with the development of GEN-1 to support the OVATION program increased
by $0.5 million to $3.3 million in 2019 compared to $2.8 million in 2018.

General and Administrative Expenses

General and administrative expenses decreased to $8.0 million in 2019 compared to $9.7 million in 2018. This decrease is primarily attributable to lower
personnel  costs  of  approximately  $1.6  million  which  included  a  $1.7  million  decrease  in  non-cash  stock  compensation  expense  partially  offset  by  an
increase in salary and benefits in 2019 compared to 2018.

Change in Earn-out Milestone Liability

The total aggregate purchase price for the acquisition of assets from EGEN included potential future earn-out payments contingent upon achievement of
certain milestones. The difference between the aggregate $30.4 million in future earn-out payments and the $13.9 million included in the fair value of the
acquisition consideration at June 20, 2014 was based on the Company’s risk-adjusted assessment of each milestone and utilizing a discount rate based on
the estimated time to achieve the milestone. These milestone payments are fair valued at the end of each quarter and any change in their value is recognized
in the consolidated financial statements.

On  March  28,  2019,  the  Company  and  EGWU,  Inc,  entered  into  an  amendment  to  the  Asset  Purchase  Agreement  discussed  in  Note  8.  Pursuant  to  the
Amended  Asset  Purchase  Agreement,  payment  of  the  earnout  milestone  liability  related  to  the  Ovarian  Cancer  Indication  of  $12.4  million  has  been
modified. The Company has the option to make the payment as follows:

● $7.0 million in cash within 10 business days of achieving the milestone; or
● $12.4 million in cash, common stock of the Company, or a combination of either, within one year of achieving the milestone.

The Company provided EGWU, Inc. 200,000 warrants to purchase common stock at a strike price of $0.01 per warrant share as consideration for entering
into the amended agreement. These warrants shares have no expiration and were fair valued at $2.00 using the closing price of a share of Celsion stock on
the  date  of  issuance  offset  by  the  exercise  price  and  recorded  $0.4  million  as  an  expense  in  the  income  statement  and  were  classified  as  equity  on  the
balance sheet during 2019.

As of December 31, 2019, the Company fair valued the earn-out milestone liability at $5.7 million and recognized a non-cash benefit of $3.2 million for
2019 as a result of the change in the fair value of these milestones from $8.9 million at December 31, 2018. In assessing the earnout milestone liability at
December 31, 2019, the Company the fair valued each of the two payment options per the Amended Asset Purchase Agreement and weighted them at 80%
and 20% probability for the $7.0 million and the $12.4 million payments, respectively.

In connection with the write down of the IPR&D asset mentioned below, the Company concluded there was a reduced probability of payments of the earn-
out milestones associated with the GBM asset as of September 30, 2018 and reduced the earnout milestone at that time. As of December 31, 2018, the
Company fair valued these milestones at $8.9 million and recognized a non-cash benefit of $3.6 million in 2018 as a result of the change in the fair value of
these milestones from $12.5 million at December 31, 2017.

Impairment of IPR&D

After our annual assessment of the totality of the events that could impair IPR&D at September 30, 2018, the Company determined certain IPR&D assets
related to the development of its GBM product candidate may be impaired. To arrive at this determination, the Company assessed the status of studies in
GBM conducted by its competitors and the Company’s strategic commitment of resources to its studies in primary liver cancer and ovarian cancer. The
Company concluded that the GBM asset, valued at $6.9 million, was partially impaired and wrote down the GBM asset to $2.5 million incurring a non-
cash charge of $4.5 million in the third quarter of 2018. The Company concluded none of the other IPR&D assets were impaired at December 31, 2018.

The Company concluded none of the IPR&D assets were impaired further as of December 31, 2019.

Investment income and interest expense

The Company realized $0.5 million and $0.4 million of investment income from its short-term investments during 2019 and 2018, respectively.

The Company entered a loan facility with Horizon Technology Finance Corporation in June 2018 and incurred interest expense of $1.4 million during 2019
compared to $0.7 million during 2018.

Income Tax Benefit

Annually, the State of New Jersey enables approved technology and biotechnology businesses with New Jersey net operating tax losses the opportunity to
sell these losses through the Technology Business Tax Certificate Program (the “NOL Program”), thereby providing cash to companies to help fund their
research and development and business operations. During the fourth quarter of 2018, the Company received eligibility from the New Jersey Economic
Development Authority to sell, and did sell, $11.1 million of its unused New Jersey net operating losses under the Technology Business Tax Certificate
Program, receiving $10.4 million of non-dilutive funding. The Company received approval from the New Jersey Economic Development Authority to sell
$1.9 million of its New Jersey net operating losses recognizing a tax benefit for the year ended December 31, 2019 for the net proceeds (approximately
$1.8 million) by reducing the deferred income tax valuation allowance. In early 2020, the Company entered into an agreement to sell these net operating
losses and expects to receive net proceeds of approximately $1.8 million in the second quarter of 2020. The Company has approximately $2.1 million in
future tax benefits remaining under the NOL Program in future years.

Inflation

We do not believe that inflation has had a material adverse impact on our revenue or operations in any of the past three years.

Financial Condition, Liquidity and Capital Resources

Since inception we have incurred significant losses and negative cash flows from operations. We have financed our operations primarily through the net
proceeds from the sales of equity, credit facilities sales of our New State net operating losses (as discussed above) and amounts received under our product
licensing agreement with Yakult and our technology development agreement with Hisun. The process of developing and commercializing ThermoDox®,
GEN-1 and other product candidates and technologies requires significant research and development work and clinical trial studies, as well as significant
manufacturing and process development efforts. We expect these activities, together with our general and administrative expenses to result in significant
operating losses for the foreseeable future. Our expenses have significantly and regularly exceeded our revenue, and we had an accumulated deficit of $291
million at December 31, 2019.

At December 31, 2019 we had total current assets of $16.2 million (including cash, cash equivalents, short-term investment, interest receivable of $14.9
million) and current liabilities of $7.9 million, resulting in net working capital of $8.3 million. At December 31, 2018 we had total current assets of $28.1
million (including cash, cash equivalents, short-term investments and interest receivable of $27.6 million) and current liabilities of $6.1 million, resulting in
net working capital of $22.0 million. We have substantial future capital requirements to continue our research and development activities and advance our
product  candidates  through  various  development  stages.  The  Company  believes  these  expenditures  are  essential  for  the  commercialization  of  its
technologies.

Net cash used in operating activities for 2019 was $20.3 million. Our net loss of $16.9 million for 2019 included the following non-cash transactions: (i)
$2.3  million  in  non-cash  stock-based  compensation  expense,  (ii)  $0.4  million  non-cash  charge  from  the  issuance  of  warrants  in  connection  with  an
amendment to the EGEN Asset Purchase Agreement (iii) $0.4 million in non-cash interest expense and (iv) $3.2 non-cash benefit based on the change in
the  earn-out  milestone  liability.  The  $20.3  million  net  cash  used  in  operating  activities  was  mostly  funded  from  cash  and  cash  equivalents,  short  term
investments, and cash proceeds received in equity financings during 2019. At December 31, 2019, we had cash, cash equivalents, short-term investment,
and interest receivable of $14.9 million.

On June 27, 2018, the Company entered into the Horizon Credit Agreement with Horizon that provided $10 million in new capital. The Company drew
down $10 million upon closing of the Horizon Credit Agreement on June 27, 2018. The Company anticipates that it will use the funding provided under the
Horizon Credit Agreement for working capital and advancement of its product pipeline. The obligations under the Horizon Credit Agreement are secured
by a first-priority security interest in substantially all assets of Celsion other than intellectual property assets. The obligations will bear interest at a rate
calculated based on one-month LIBOR plus 7.625%. Payments under the loan agreement are interest only for the first twenty-four (24) months after loan
closing, followed by a 24-month amortization period of principal and interest through the scheduled maturity date.

On August 31, 2018, the Company entered into the 2018 Aspire Purchase Agreement with Aspire Capital Fund LLC (“Aspire Capital”) which provides
that, upon the terms and subject to the conditions and limitations set forth therein, Aspire Capital is committed to purchase up to an aggregate of $15.0
million of shares of the Company’s common stock over the 24-month term of the 2018 Aspire Purchase Agreement. On October 12, 2018, the Company
filed with the SEC a prospectus supplement to the 2018 Shelf Registration Statement registering all of the shares of common stock that may be offered to
Aspire Capital from time to time. The timing and amount of sales of the Company’s common stock to Aspire Capital. Aspire Capital has no right to require
any sales by the Company but is obligated to make purchases from the Company as directed by the Company in accordance with the Purchase Agreement.
There  are  no  limitations  on  use  of  proceeds,  financial  or  business  covenants,  restrictions  on  future  funding,  rights  of  first  refusal,  participation  rights,
penalties or liquidated damages in the Purchase Agreement. In consideration for entering into the Purchase Agreement, concurrently with the execution of
the Purchase Agreement, the Company issued to Aspire Capital 164,835 Commitment Shares. The 2018 Aspire Purchase Agreement may be terminated by
the  Company  at  any  time,  at  its  discretion,  without  any  cost  to  the  Company.  During  2018  and  2019  the  Company  sold  and  issued  an  aggregate  of  3.4
million  shares  under  the  Purchase  Agreement,  receiving  approximately  $6.5  million.  All  proceeds  from  the  Company  received  under  the  2018  Aspire
Purchase Agreement were used for working capital and general corporate purposes. As a result of the Company and Aspire Capital entering into a new
purchase agreement on October 28, 2019 as discussed in the next paragraph, the 2018 Aspire Purchase Agreement terminated.

On October 28, 2019, Company, entered into the 2019 Aspire Purchase Agreement with Aspire Capital. The terms and conditions pursuant to the 2019
Aspire  Purchase  Agreement  are  substantially  similar  to  the  2018  Aspire  Purchase  Agreement.  Pursuant  to  the  new  2019 Aspire  Purchase  Agreement,
Aspire Capital is committed to purchase up to an aggregate of $10.0 million of shares of the Company’s common stock over the 24-month term of the 2019
Aspire  Purchase  Agreement.  Concurrently  with  entering  into  the  2019  Aspire  Purchase Agreement,  the  Company  also  entered  into  a  registration  rights
agreement  with  Aspire  Capital  (the  “Registration  Rights  Agreement”),  in  which  the  Company  agreed  to  file  one  or  more  registration  statements,  as
permissible  and  necessary  to  register  under  the  Securities  Act  of  1933,  as  amended  (the  “Securities  Act”),  registering  the  sale  of  the  shares  of  the
Company’s common stock that have been and may be issued to Aspire Capital under the 2019 Aspire Purchase Agreement. In consideration for entering
into the 2019 Aspire Purchase Agreement, the Company issued to Aspire Capital an additional 100,000 Commitment Shares. On November 8, 2019, the
Company filed with the SEC a Registration Statement on Form S-1 registering all the shares of common stock that may be offered to Aspire Capital from
time to time under the 2019 Aspire Purchase Agreement. During 2019, the Company sold 0.5 million shares under the 2019 Aspire Purchase Agreement,
receiving approximately $0.7 million. On March 5, 2020, the Company delivered notice to Aspire Capital terminating the 2019 Aspire Purchase Agreement
with Aspire Capital effective as of March 6, 2020. The Company sold 1.0 million shares receiving $1.6 million during 2020 until the date of termination
under the 2019 Aspire Purchase Agreement.

We were a party to a Controlled Equity OfferingSM Sales Agreement (ATM) dated as of February 1, 2013 with Cantor Fitzgerald & Co., pursuant to which
we may sell additional shares of our common stock having an aggregate offering price of up to $25 million through “at-the-market” equity offerings from
time to time. During 2018, the Company sold 0.5 million shares of common stock under the ATM, receiving approximately $1.2 million in net proceeds.
On October 10, 2018, the Company delivered notice to Cantor terminating the ATM effective as of October 20, 2018. From February 2013 through the date
of  termination,  the  Company  sold  1.8  million  shares  of  Common  Stock  under  the  Sales  Agreement  generating  gross  proceeds  of  $12.8  million.  The
Company has no further obligations under the Sales Agreement.

On December 4, 2018, the Company entered into a new Capital on DemandTM Sales Agreement (the “Capital on Demand Agreement”) with JonesTrading
Institutional Services LLC, as sales agent (“JonesTrading”), pursuant to which the Company may offer and sell, from time to time, through JonesTrading
shares of Common Stock having an aggregate offering price of up to $16.0 million. The Company intends to use the net proceeds from the offering, if any,
for general corporate purposes, including research and development activities, capital expenditures and working capital. The Company is not obligated to
sell  any  Common  Stock  under  the  Capital  on  Demand  Agreement  and,  subject  to  the  terms  and  conditions  of  the  Capital  on  Demand  Agreement,
JonesTrading will use commercially reasonable efforts, consistent with its normal trading and sales practices and applicable state and federal law, rules and
regulations and the rules of The Nasdaq Capital Market, to sell Common Stock from time to time based upon Celsion’s instructions, including any price,
time or size limits or other customary parameters or conditions the Company may impose. Under the Capital on Demand Agreement, JonesTrading may
sell  Common  Stock  by  any  method  deemed  to  be  an  “at  the  market  offering”  as  defined  in  Rule  415  promulgated  under  the  Securities  Act  of  1933,  as
amended.  The  Capital  on  Demand  Agreement  will  terminate  upon  the  earlier  of  (i)  the  sale  of  all  shares  of  our  common  stock  subject  to  the  Sales
Agreement,  and  (ii)  the  termination  of  the  Capital  on  Demand  Agreement  by  JonesTrading  or  Celsion.  The  Capital  on  Demand  Agreement  may  be
terminated by JonesTrading or the Company at any time upon 10 days’ notice to the other party, or by JonesTrading at any time in certain circumstances,
including the occurrence of a material adverse change in the Company. The Company did not sell any shares under the Capital on Demand Agreement
during 2018. During 2019, the Company sold 0.5 million shares under the Capital on Demand Agreement, receiving approximately $1.0 million.

On February 27, 2020, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with several institutional investors, pursuant to which
we agreed to issue and sell, in a registered direct offering (the “February 2020 Offering”), an aggregate of 4,571,428 shares (the “Shares”) of our common
stock at an offering price of $1.05 per share for gross proceeds of approximately $4.8 million before the deduction of the Placement Agent fees and offering
expenses.  The  Shares  were  offered  by  the  Company  pursuant  to  a  registration  statement  on  Form  S-3  (File  No.  333-227236).  The  Purchase  Agreement
contains customary representations, warranties and agreements by the Company and customary conditions to closing. In a concurrent private placement
(the  “Private  Placement”),  the  Company  agreed  to  issue  to  the  investors  that  participated  in  the  Offering,  for  no  additional  consideration,  warrants,  to
purchase up to 2,971,428 shares of Common Stock (the “Original Warrants”). The Original Warrants were initially exercisable six months following their
and were set to expire on the five-year anniversary of such initial exercise date. The Warrants had an exercise price of $1.15 per share subject to adjustment
as provided therein. On March 12, 2020 the Company entered into private exchange agreements (the “Exchange Agreements”) with holders the Warrants.
Pursuant to the Exchange Agreements, in return for a higher exercise price of $1.24 per share of Common Stock, the Company issued new warrants to the
Investors to purchase up to 3,200,000 shares of Common Stock (the “Exchange Warrants”) in exchange for the Original Warrants. The Exchange Warrants,
like the Original Warrants, are initially exercisable six months following their issuance (the “Initial Exercise Date”) and expire on the five-year anniversary
of  their  Initial  Exercise  Date.  Other  than  having  a  higher  exercise  price,  different  issue  date,  Initial  Exercise  Date  and  expiration  date,  the  terms  of  the
Exchange Warrants are identical to those of the Original Warrants.

The Company had $16.7 million in cash, investments, interest receivable and deferred income tax asset as of December 31, 2019, as well as $6.4 million
we have raised thus far in 2020 under the 2019 Aspire Purchase Agreement and the February 2020 Offering. Given our development plans, we anticipate
cash resources will be sufficient to fund our operations through mid-2020. The Company has approximately $15 million available under the Capital on
Demand Agreement with JonesTrading International Services LLC. On March 5, 2020, we terminated the 2019 Aspire Purchase Agreement. Other than the
Capital on Demand Agreement that provides us the ability to sell equity securities in the future, we have no other committed sources of additional capital.
However, our future capital requirements will depend upon numerous unpredictable factors, including, without limitation, the cost, timing, progress and
outcomes of clinical studies and regulatory reviews of our proprietary drug candidates, our efforts to implement new collaborations, licenses and strategic
transactions, general and administrative expenses, capital expenditures and other unforeseen uses of cash.

The  Company  may  seek  additional  capital  through  further  public  or  private  equity  offerings,  debt  financing,  additional  strategic  alliance  and  licensing
arrangements, collaborative arrangements, or some combination of these financing alternatives. If we raise additional funds through the issuance of equity
securities, the percentage ownership of our stockholders could be significantly diluted, and the newly issued equity securities may have rights, preferences,
or privileges senior to those of the holders of our common stock. If we raise funds through the issuance of debt securities, those securities may have rights,
preferences,  and  privileges  senior  to  those  of  our  common  stock.  If  we  seek  strategic  alliances,  licenses,  or  other  alternative  arrangements,  such  as
arrangements with collaborative partners or others, we may need to relinquish rights to certain of our existing or future technologies, product candidates, or
products we would otherwise seek to develop or commercialize on our own, or to license the rights to our technologies, product candidates, or products on
terms  that  are  not  favorable  to  us.  The  overall  status  of  the  economic  climate  could  also  result  in  the  terms  of  any  equity  offering,  debt  financing,  or
alliance, license, or other arrangement being even less favorable to us and our stockholders than if the overall economic climate were stronger. We also will
continue to look for government sponsored research collaborations and grants to help offset future anticipated losses from operations and, to a lesser extent,
interest income.

If adequate funds are not available through either the capital markets, strategic alliances, or collaborators, we may be required to delay or, reduce the scope
of, or terminate our research, development, clinical programs, manufacturing, or commercialization efforts, or effect additional changes to our facilities or
personnel, or obtain funds through other arrangements that may require us to relinquish some of our assets or rights to certain of our existing or future
technologies, product candidates, or products on terms not favorable to us.

Contractual Obligations

In  July  2011,  we  entered  into  a  lease  with  Brandywine  Operating  Partnership,  L.P.,  a  Delaware  limited  partnership  for  a  10,870  square  foot  premises
located in Lawrenceville, New Jersey in connection with the relocation of our offices from Columbia, Maryland. In late 2015, Lenox Drive Office Park
LLC, purchased the real estate and office building and assumed the lease. Under the current terms of the lease, which was amended effective May 1, 2017
and  is  set  to  expire  on  September  1,  2022,  we  reduced  the  size  of  the  premises  to  7,565  square  feet  and  are  paying  a  monthly  rent  that  ranges  from
approximately $18,900 in the first year to approximately $20,500 in the final year of the amendment. On February 1, 2019, we amended the current terms
of the lease to increase the size of the premises by 2,285 square feet to 9,850 square feet and also extended the lease term by one year to September 1, 2023.
In conjunction with the February 1, 2019 lease amendment, we agreed to modify our one-time option to cancel the lease as of the 36th month after the May
1, 2017 lease commencement date.

In connection with the Asset Purchase Agreement, in June 2014, we assumed the existing lease with another landlord for an 11,500 square foot premises
located  in  Huntsville,  Alabama.  In  January  2018,  we  entered  into  a  new  60-month  lease  agreement  for  9,049  square  feet  with  rent  payments  of
approximately $18,100 per month.

Following is a table of the lease payments and maturity of our operating lease liabilities as of December 31, 2019:

lease expense was $450,430 and cash paid for operating leases included in operating cash flows was $457,321.

Off-Balance Sheet Arrangements

We do not utilize off-balance sheet financing arrangements as a source of liquidity or financing.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The  primary  objective  of  our  cash  investment  activities  is  to  preserve  principal  while  at  the  same  time  maximizing  the  income  we  receive  from  our
investments  without  significantly  increasing  risk.  Some  of  the  securities  that  we  invest  in  may  be  subject  to  market  risk.  This  means  that  a  change  in
prevailing  interest  rates  may  cause  the  principal  amount  of  the  investment  to  fluctuate.  For  example,  if  we  hold  a  security  that  was  issued  with  a  fixed
interest rate at the then-prevailing rate and the interest rate later rises, the principal amount of our investment will probably decline. A hypothetical 50 basis
point increase in interest rates reduces the fair value of our available-for-sale securities at December 31, 2019 by an immaterial amount. To minimize this
risk in the future, we intend to maintain our portfolio of cash equivalents and marketable securities in a variety of securities, including commercial paper,
government and non-government debt securities and/or money market funds that invest in such securities. We have no holdings of derivative financial or
commodity  instruments.  As  of  December  31,  2019,  our  investments  consisted  of  investments  in  corporate  notes  and  obligations  or  in  money  market
accounts and checking funds with variable market rates of interest. We believe our credit risk is immaterial.

ITEM 9A. CONTROLS AND PROCEDURES

(a)

Disclosure Controls and Procedures

We have conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in
Rules  13a-15(e)  and  15d-15(e)  under  the  Securities  Exchange  Act  of  1934,  as  amended  (the  Exchange  Act))  under  the  supervision,  and  with  the
participation, of our management, including our principal executive officer and principal financial officer. Based on that evaluation, our principal executive
officer and principal financial officer concluded that as of December 31, 2019, which is the end of the period covered by this Annual Report, our disclosure
controls and procedures are effective.

(b)

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 Securities Exchange Act of 1934. Our internal control over financial reporting is a process designed by, or under the supervision of, our
chief executive officer and chief financial officer, or persons performing similar functions, and effected by our 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 accounting principles generally accepted in the United States of America (GAAP). Our internal control over financial reporting includes
those  policies  and  procedures  that:  (i)  pertain  to  the  maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and
disposition of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial
statements  in  accordance  with  GAAP  and  that  receipts  and  expenditures  of  the  Company  are  being  made  only  in  accordance  with  authorization  of
management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition,
use, or disposition of the Company’s assets that could have a material effect on the financial statements.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2019. In making this assessment,
management  used  the  criteria  set  forth  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  in  the  2013  Internal  Control-
Integrated Framework. Based on its evaluation, management has concluded that the Company’s internal control over financial reporting is effective as of
December 31, 2019.

Pursuant  to  Regulation  S-K  Item  308(b),  this  Annual  Report  does  not  include  an  attestation  report  of  our  company’s  registered  public  accounting  firm
regarding internal control over financial reporting.

Because of its 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. A control system, no matter how well designed and operated can provide only reasonable, but
not  absolute,  assurance  that  the  control  system’s  objectives  will  be  met.  The  design  of  a  control  system  must  reflect  the  fact  that  there  are  resource
constraints, and the benefits of controls must be considered relative to their cost.

(c)

Changes in Internal Control over Financial Reporting

There  have  been  no  changes  in  our  internal  control  over  financial  reporting  in  the  fiscal  quarter  ended  December  31,  2019,  which  were  identified  in
connection with our management’s evaluation required by paragraph (d) of rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected,
or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of
Celsion Corporation:

Opinion on the Consolidated Financial Statements 

We have audited the accompanying consolidated balance sheets of Celsion Corporation (the “Company”) as of December 31, 2019 and 2018, the related
consolidated statements of operations, comprehensive loss, changes in stockholders' equity, and cash flows for each of the two years in the period ended
December 31, 2019 and 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 each of
the two years in the period ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

Adoption of New Accounting Standard

As discussed in Note 1 to the consolidated financial statements, the Company changed its method of accounting for leases in 2019 due to the adoption of
ASU 2016-02, Leases (Topic 842).

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 in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit 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.

/s/ WithumSmith+Brown, PC
WithumSmith+Brown, PC

We have served as the Company's auditor since 2017.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2019 AND 2018

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business

Celsion Corporation (“Celsion” and the “Company”) is an integrated development clinical stage oncology drug company focused on advancing innovative
cancer  treatments,  including  directed  chemotherapies,  DNA-mediated  immunotherapy  and  RNA-based  therapies.  Our  lead  product  candidate  is
ThermoDox®, a proprietary heat-activated liposomal encapsulation of doxorubicin, currently in a Phase III clinical trial for the treatment of primary liver
cancer (the “OPTIMA Study”). Second in our product pipeline is GEN-1, a DNA-mediated immunotherapy for the localized treatment of ovarian cancer.
These investigational products are based on platform technologies that provide the basis for future development of a range of therapeutics, largely focused
on difficult-to-treat forms of cancer. The first platform technology is Lysolipid Thermally Sensitive Liposomes, a heat sensitive liposomal based dosage
form that is designed to target disease with known chemotherapeutics in the presence of mild heat. The second platform technology is TheraPlas, a novel
nucleic acid-based investigational candidate under development for local transfection of therapeutic DNA plasmids. Employing these technologies, we are
working  to  develop  and  commercialize  more  efficient,  effective  and  targeted  oncology  therapies  that  maximize  efficacy  while  minimizing  side  effects
common to cancer treatments.

Basis of Presentation

The  accompanying  consolidated  financial  statements  of  Celsion  have  been  prepared  in  accordance  with  generally  accepted  accounting  principles
(“GAAP”)  in  the  United  States  and  include  the  accounts  of  the  Company  and  CLSN  Laboratories,  Inc.  All  significant  intercompany  balances  and
transactions have been eliminated. The preparation of financial statements in conformity with GAAP requires management to make judgments, estimates,
and assumptions that affect the amount reported in the Company’s financial statements and accompanying notes. Actual results could differ materially from
these estimates.

Events and conditions arising subsequent to the most recent balance sheet date through the date of the issuance of these consolidated financial statements
have  been  evaluated  for  their  possible  impact  on  the  financial  statements  and  accompanying  notes.  No  events  and  conditions  would  give  rise  to  any
information that required accounting recognition or disclosure in the financial statements other than those arising in the ordinary course of business.

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires the Company to make estimates and assumptions that affect the reported
amounts  of  assets  and  liabilities  and  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  the  financial  statements  and  the  reported  amounts  of
expenses during the reporting period.

On  an  ongoing  basis,  the  Company  evaluates  its  estimates  using  historical  experience  and  other  factors,  including  the  current  economic  environment.
Significant  items  subject  to  such  estimates  are  assumptions  used  for  purposes  of  determining  stock-based  compensation,  the  fair  value  of  the  earn-out
milestone liabilities, estimates for contingent liabilities, if any, and accounting for valuation of in-process research and development assets. Management
believes its estimates to be reasonable under the circumstances. Actual results could differ significantly from those estimates. Significant estimates in these
financials are the valuation of options granted and valuation methods used to determine the recoverability of goodwill and other intangible assets.

Revenue Recognition

On January 1, 2018, the Company adopted the new accounting standard ASC 606, Revenue from Contracts with Customers and all related amendments
(the “new revenue standard”) to all contracts with customers using the modified retrospective method. The adoption of the new revenue standard had no
impact on retained earnings as of December 31, 2017 and, accordingly, no cumulative adjustment was required. We do not expect the new revenue standard
to have a significant impact on our net income on an ongoing basis. The Company’s sole revenue stream is related to the Hisun agreement described in
Note  16.  There  were  no  accounts  receivable  as  of  December  31,  2019  or  2018.  Contract  liabilities  from  the  Hisun  agreement  amounted  to  $1,500,000,
$2,000,000 and $2,500,000 at December 31, 2019, 2018and 2017, respectively. Contract liabilities values represent the value of cash received before the
services were provided.

F-10

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and investments purchased with an original maturity of three months or less. A portion of these funds are
not covered by FDIC insurance.

Fair Value of Investment in Debt Securities

The carrying values of investment securities approximate their respective fair values.

Short Term Investments

The  Company  classifies  its  investments  in  debt  securities  with  readily  determinable  fair  values  as  investments  available-for-sale  in  accordance  with
Accounting  Standards  Codification  (ASC)  320,  Investments  -  Debt  and  Equity  Securities.  Available-for-sale  securities  consist  of  debt  securities  not
classified as trading securities or as securities to be held to maturity. The Company has classified all of its investments as available-for-sale. Unrealized
holding gains and losses on available-for-sale securities are reported as a net amount in accumulated other comprehensive gain or loss in stockholders’
equity until realized. Gains and losses on the sale of available-for-sale securities are determined using the specific identification method. The Company’s
short-term investments consist of corporate bonds.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is provided over the estimated useful lives of the
related assets, ranging from three to seven years, using the straight-line method. Amortization is recognized over the lesser of the life of the asset or the
lease  term.  Major  renewals  and  improvements  are  capitalized  at  cost  and  ordinary  repairs  and  maintenance  are  charged  against  operating  expenses  as
incurred. Depreciation expense was approximately $128,500 and $130,000 for the years ended December 31, 2019 and 2018, respectively.

The Company reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset
may not be recoverable. An asset is considered impaired if its carrying amount exceeds the future net undiscounted cash flows that the asset is expected to
generate. If such asset is considered to be impaired, the impairment recognized is the amount by which the carrying amount of the asset, if any, exceeds its
fair value determined using a discounted cash flow model.

Deposits

Deposits include real property security deposits and other deposits which are contractually required and of a long-term nature.

In-Process Research and Development, Other Intangible Assets and Goodwill

During  2014,  the  Company  acquired  certain  assets  of  EGEN,  Inc.  As  more  fully  described  in  Note  5,  the  acquisition  was  accounted  for  under  the
acquisition method of accounting which required the Company to perform an allocation of the purchase price to the assets acquired and liabilities assumed.
Under the acquisition method of accounting, the total purchase price is allocated to net tangible and intangible assets and liabilities based on their estimated
fair values as of the acquisition date.

Impairment or Disposal of Long-Lived Assets

The Company assesses the impairment of its long-lived assets under accounting standards for the impairment or disposal of long-lived assets whenever
events  or  changes  in  circumstances  indicate  that  the  carrying  value  may  not  be  recoverable.  For  long-lived  assets  to  be  held  and  used,  the  Company
recognizes an impairment loss only if its carrying amount is not recoverable through its undiscounted cash flows and measures the impairment loss based
on the difference between the carrying amount and fair value.

F-11

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Comprehensive Income (Loss)

Accounting  Standards  Codification  (“ASC”)  220,  Comprehensive  Income,  establishes  standards  for  the  reporting  and  display  of  comprehensive  income
(loss) and its components in the Company’s consolidated financial statements. The objective of ASC 220 is to report a measure comprehensive income
(loss)  of  all  changes  in  equity  of  an  enterprise  that  result  from  transactions  and  other  economic  events  in  a  period  other  than  transactions  with  owners.
Comprehensive gains (losses) result from changes in unrealized gains and losses from investment in debt securities.

Research and Development

Research and development costs are expensed as incurred. Equipment and facilities acquired for research and development activities that have alternative
future uses are capitalized and charged to expense over their estimated useful lives.

Net Loss Per Common Share

Basic and diluted net loss per common share was computed by dividing net loss for the year by the weighted average number of shares of common stock
outstanding,  both  basic  and  diluted,  during  each  period.  The  impact  of  common  stock  equivalents  has  been  excluded  from  the  computation  of  diluted
weighted average common shares outstanding in periods where there is a net loss, as their effect is anti-dilutive.

For the years ended December 31, 2019 and 2018, the total number of shares of common stock issuable upon exercise of warrants and equity awards is
4,766,990  and  4,764,405  respectively.  Warrants  with  an  exercise  price  of  $0.01  (as  more  fully  described  in  Note  13  of  these  financial  statements)
exercisable for 200,000 shares of common stock were considered issued in calculating basic loss per share. For the year ended December 31, 2019 and
2018, diluted loss per common share is the same as basic loss per common share as all options and all other warrants that were convertible into shares of
the  Company’s  common  stock  were  excluded  from  the  calculation  of  diluted  earnings  attributable  to  common  stockholders  per  common  share  as  their
effect would be anti-dilutive.

Income Taxes

Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases
and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income
in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax asset and liabilities of a change in tax
rates is recognized in results of operations in the period that the tax rate change occurs. Valuation allowances are established, when necessary, to reduce
deferred tax assets to the amount expected to be realized. In accordance with ASC 740, Income Taxes, a tax position is recognized as a benefit only if it is
“more likely than not” that the tax position taken would be sustained in a tax examination, presuming that a tax examination will occur. The Company
recognizes interest and/or penalties related to income tax matters in the income tax expense category.

As more fully discussed in Note 9, the Company received approval from the New Jersey Economic Development Authority to sell $1.9 million of its New
Jersey net operating losses recognizing a tax benefit for the year ended December 31, 2019 for the net proceeds (approximately $1.8 million) by reducing
the deferred income tax valuation allowance. In early 2020, the Company entered into an agreement to sell these net operating losses and expects to receive
net proceeds of approximately $1.8 million in the second quarter of 2020. In 2018, the Company completed the sale of a portion of its New Jersey net
operating losses for 2011 - 2017 totaling approximately $11.1 for net proceeds of approximately $10.4 million in December 2018. The proceeds of $10.4
million were reflected as a tax benefit for the year ended December 31, 2018.

Stock-Based Compensation

In  March  2016,  the  FASB  issued  ASU  2016-09,  Compensation-Stock  Compensation,  which  simplifies  various  aspects  of  accounting  for  share-based
payments.  The  areas  for  simplification  involve  several  aspects  of  the  accounting  for  share-based  payment  transactions,  including  the  income  tax
consequences and classification on the statements of cash flows. The Company recognizes the effect of forfeitures in compensation cost when they occur.

Recent Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) and are adopted by us as of the
specified  effective  date.  Unless  otherwise  discussed,  we  believe  that  the  impact  of  recently  issued  accounting  pronouncements  will  not  have  a  material
impact on the Company’s consolidated financial position, results of operations, and cash flows, or do not apply to our operations.

In  February  2016,  the  FASB  issued  Accounting  Standards  Update  No.  2016-02,  “Leases”  -  Topic  842  (ASC  Topic  842),  which  requires  that  lessees
recognize assets and liabilities for leases with lease terms greater than twelve months in the statement of financial position. Leases will be classified as
either finance or operating, with classification affecting the pattern of expense recognition in the income statement. This update also requires improved
disclosures to help users of financial statements better understand the amount, timing and uncertainty of cash flows arising from leases. The update became
effective  for  fiscal  years  beginning  after  December  15,  2018,  including  interim  reporting  periods  within  that  reporting  period.  The  FASB  subsequently
issued the following amendments to ASC Topic 842, which have the same effective date and transition date of January 1, 2019:

●

●

ASU No. 2018-10, Codification Improvements to Topic 842, Leases, which amends certain narrow aspects of the guidance issued in ASU 2016-
02; and

ASU No.  2018-11,  Leases  (Topic  842):  Targeted  Improvements,  which  allows  for  a  transition  approach  to  initially  apply  ASU  2016-02  at  the
adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption as well as an
additional practical expedient for lessors to not separate non-lease components from the associated lease component.

We adopted Topic ASC 842 effective January 1, 2019 and elected to apply the available practical expedients and implement internal controls to enable the
preparation of financial information on adoption. We identified two of our leases consisting of the New Jersey corporate office lease and the Alabama lab
facility  lease  as  being  subject  to  Topic  ASC  842.  The  adoption  of  this  standard  resulted  in  the  recognition  of  right-of-use  assets  of  approximately  $1.4
million, related operating lease liabilities of $1.5 million and reduced other liabilities by approximately $0.1 million on the consolidated balance sheets as
of January 1, 2019 with no material impact to the opening balance of retained earnings. See Note 15 for further discussions regarding the adoption of ASC
Topic 842.

In  June  2016,  the  FASB  issued  Accounting  Standard  Update  No.  2016-13,  “Financial  Instruments  –  Credit  Losses  (Topic  326):  Measurement  of  Credit
Losses on Financial Instruments”, which modifies the measurement of expected credit losses on certain financial instruments. The Company expects to
adopt  ASU  2016-13  in  its  first  quarter  of  2021  utilizing  the  modified  retrospective  transition  method.  Based  on  the  composition  of  the  Company’s
investment portfolio and current market conditions, the adoption of ASU 2016-13 is not expected to have a material impact on its consolidated financial
statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement: Disclosure Framework – Changes to the Disclosure Requirements for Fair
Value Measurement, which adds and modifies certain disclosure requirements for fair value measurements. Under the new guidance, entities will no longer
be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, or valuation processes for Level 3
fair value measurements. However, public companies will be required to disclose the range and weighted average of significant unobservable inputs used to
develop  Level  3  fair  value  measurements,  and  related  changes  in  unrealized  gains  and  losses  included  in  other  comprehensive  income.  This  update  is
effective for annual periods beginning after December 15, 2019, and interim periods within those periods, and early adoption is permitted. The Company is
in the process of determining the impact the adoption will have on its financial statements.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740). The standard simplifies the accounting for incomes taxes by removing
certain exceptions to the general principles in Topic 740 related to the approach for intraperiod tax allocation and the recognition of deferred tax liabilities
for outside basis differences. The standard also clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The standard
also improves consistent application of and simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendment is
effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted. The Company is
currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements.

2. FINANCIAL CONDITION

Since  inception,  the  Company  has  incurred  substantial  operating  losses,  principally  from  expenses  associated  with  the  Company’s  research  and
development programs, clinical trials conducted in connection with the Company’s product candidates, and applications and submissions to the U.S. Food
and Drug Administration. We have not generated significant revenue and have incurred significant net losses in each year since our inception. We have
incurred approximately $291 million of cumulated net losses. As of December 31, 2019, we had approximately $16.7 million in cash, investment securities,
interest receivable and deferred income tax asset. We have substantial future capital requirements to continue our research and development activities and
advance our product candidates through various development stages. The Company believes these expenditures are essential for the commercialization of
its technologies.

The Company expects its operating losses to continue for the foreseeable future as it continues its product development efforts, and when it undertakes
marketing and sales activities. The Company’s ability to achieve profitability is dependent upon its ability to obtain governmental approvals, manufacture,
and market and sell its new product candidates. There can be no assurance that the Company will be able to commercialize its technology successfully or
that profitability will ever be achieved. The operating results of the Company have fluctuated significantly in the past. We have substantial future capital
requirements  associated  with  our  continued  research  and  development  activities  and  to  advance  our  product  candidates  through  various  stages  of
development.  The  Company  believes  these  expenditures  are  essential  for  the  commercialization  of  its  technologies.  In  January  2020,  the  World  Health
Organization  (WHO)  declared  an  outbreak  of  coronavirus,  COVID-19,  to  be  a  “Public  Health  Emergency  of  International  Concern,”  and  the  U.S.
Department of Health and Human Services declared a public health emergency to aid the U.S. healthcare community in responding to COVID-19. This
virus continues to spread globally and, as of late March 2020, has spread to over 100 countries, including the United States. Our ability to raise additional
capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, financial markets in
the United States and worldwide resulting from the ongoing COVID-19 pandemic.

The disruptions caused by COVID-19 may also disrupt the clinical trials process and enrollment of patients. This may delay commercialization efforts. The
Company is currently monitoring its operating activities in light of these events and it is reasonably possible that the virus could have a negative effect on
the Company’s financial condition and results of operations, the specific impact is not readily determinable as of the date of these financial statements.

The actual amount of funds the Company will need to operate is subject to many factors, some of which are beyond the Company’s control. These factors
include the following:

● the progress of research activities;

● the number and scope of research programs;

● the progress of preclinical and clinical development activities;

● the progress of the development efforts of parties with whom the Company has entered into research and development agreements;

● the costs associated with additional clinical trials of product candidates;

● the ability to maintain current research and development licensing arrangements and to establish new research and development and licensing

arrangements;

● the ability to achieve milestones under licensing arrangements;

● the costs involved in prosecuting and enforcing patent claims and other intellectual property rights; and

● the costs and timing of regulatory approvals.

The Company has based its estimate on assumptions that may prove to be wrong. The Company may need to obtain additional funds sooner or in greater
amounts than it currently anticipates. Potential sources of financing include strategic relationships, public or private sales of the Company’s shares or debt,
the additional sales from the sale of its State of New Jersey net operating losses in the future and other sources. If the Company raises funds by selling
additional shares of common stock or other securities convertible into common stock, the ownership interest of existing stockholders may be diluted.

During 2019 and 2018, the Company submitted an application to sell a portion of the Company’s New Jersey NOLs as part of the Technology Business Tax
Certificate Program sponsored by The New Jersey Economic Development Authority. Under the program, emerging biotechnology companies with unused
NOLs and unused research and development credits are allowed to sell these benefits to other companies. As more fully discussed in Note 9, the Company
received  approval  from  the  New  Jersey  Economic  Development  Authority  to  sell  $1.9  million  of  its  New  Jersey  net  operating  losses  recognizing  a  tax
benefit for the year ended December 31, 2019 for the net proceeds (approximately $1.8 million) by reducing the deferred income tax valuation allowance.
In early 2020, the Company entered into an agreement to sell these net operating losses and expects to receive net proceeds of approximately $1.8 million
in  the  second  quarter  of  2020.  In  2018,  the  Company  completed  the  sale  of  a  portion  of  its  New  Jersey  net  operating  losses  for  2011  -  2017  totaling
approximately $11.1 for net proceeds of approximately $10.4 million in December 2018. The proceeds of $10.4 million were reflected as a tax benefit for
the year ended December 31, 2018. The Company has approximately $2.1 million in future tax benefits remaining under the NOL Program for future years.

With $16.7 million in cash, investment securities, interest receivable and deferred income tax asset at December 31, 2019, as well as the $6.4 million raised
in equity financings so far in 2020 (Note 10), the Company believes it has sufficient capital resources to fund its operations and financial commitments thru
mid-2021. The Company will be required to obtain additional funding to continue development of its current product candidates within the anticipated time
periods, if at all, and to continue to fund operations. As more fully discussed in Note 10, the Company has approximately $15 million available for future
sale of equity securities under the common stock sales agreement with JonesTrading International Services LLC.

3. INVESTMENTS IN DEBT SECURITIES AVAILABLE FOR SALE

Investments in debt securities available for sale of $7,985,886 and $14,257,998 as of December 31, 2019 and 2018, respectively, consist of corporate debt
securities. These investments are valued at estimated fair value, with unrealized gains and losses reported as a separate component of stockholders’ equity
in accumulated other comprehensive loss.

Investments in debt securities available for sale are evaluated periodically to determine whether a decline in their value is other than temporary. The term
“other than temporary” is not intended to indicate a permanent decline in value. Rather, it means that the prospects for near term recovery of value are not
necessarily favorable, or that there is a lack of evidence to support fair values equal to, or greater than, the carrying value of the security. Management
reviews criteria such as the magnitude and duration of the decline, as well as the reasons for the decline, to predict whether the loss in value is other than
temporary. Once a decline in value is determined to be other than temporary, the value of the security is reduced and a corresponding charge to earnings is
recognized.

FASB Accounting Standards Codification (ASC) Section 820 “Fair Value Measurements and Disclosures,” establishes a three-level hierarchy for fair value
measurements which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.
The three levels of inputs that may be used to measure fair value are as follows:

Level 1: Quoted prices (unadjusted) or identical assets or liabilities in active markets that the entity has the ability to access as of the measurement
date;

Level  2:  Significant  other  observable  inputs  other  than  Level  1  prices  such  as  quoted  prices  for  similar  assets  or  liabilities;  quoted  prices  in
markets that are not active; or other inputs that are observable or can be corroborated by observable market data; and

Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions that market participants would use in pricing an asset or
liability.

Cash and cash equivalents, other current assets, accounts payable and other accrued liabilities are reflected in the condensed consolidated balance sheet at
their approximate estimated fair values primarily due to their short-term nature. The fair values of securities available for sale is determined by relying on
the  securities’  relationship  to  other  benchmark  quoted  securities  and  classified  its  investments  as  Level  2  items  in  both  2019  and  2018.  There  were  no
transfers of assets or liabilities between Level 1 and Level 2 and no transfers in or out of Level 3 during the year ended December 31, 2019 or 2018. The
changes in Level 3 liabilities were the result of changes in the fair value of the earn-out milestone liability included in earnings and in-process R&D. The
earnout milestone liability is valued using a risk-adjusted assessment of the probability of payment of each milestone, discounted to present value using an
estimated time to achieve the milestone (see Note 12). The in-process R&D – GBM is valued using a multi-period excess earnings method (see note 5).

$

In June 2014, we completed the acquisition of substantially all of the assets of EGEN, Inc., an Alabama corporation, which has changed its company name
to EGWU, Inc. after the closing of the acquisition (“EGEN”). We acquired all of EGEN’s right, title and interest in and to substantially all of the assets of
EGEN, including cash and cash equivalents, patents, trademarks and other intellectual property rights, clinical data, certain contracts, licenses and permits,
equipment,  furniture,  office  equipment,  furnishings,  supplies  and  other  tangible  personal  property.  In  addition,  CLSN  Laboratories  assumed  certain
specified liabilities of EGEN, including the liabilities arising out of the acquired contracts and other assets relating to periods after the closing date.

Acquired In-process Research and Development

Acquired in-process research and development (IPR&D) consists of EGEN’s drug technology platforms: TheraPlas and TheraSilence. The fair value of the
IPR&D  drug  technology  platforms  was  estimated  to  be  $24.2  million  as  of  the  acquisition  date.  As  of  the  closing  of  the  acquisition,  the  IPR&D  was
considered indefinite lived intangible assets and will not be amortized. IPR&D is reviewed for impairment at least annually as of our third quarter ended
September 30, and whenever events or changes in circumstances indicate that the carrying value of the assets might not be recoverable. On December 31,
2016, the Company determined one of its IPR&D assets related to its RNA delivery system was impaired and wrote off its fair value, incurring a non-cash
charge of $1.4 million during 2016. During its annual assessments on September 30, 2017 and 2018, the Company determined its IPR&D asset related to
its glioblastoma multiforme cancer (GBM) product candidate, originally fair valued at $9.4 million on the date of acquisition, was impaired and wrote this
asset’s carrying value down to $2.4 million collectively after those two assessments, incurring non-cash charges of $2.5 million and $4.5 million during
2017 and 2018, respectively. On September 30, 2019, the Company evaluated its IPR&D of the (GBM) product candidate and concluded that it is not more
likely than not that the asset is further impaired. As no other indicators of impairment existed during the fourth quarter of 2019, the Company concluded
none of the other IPR&D assets were impaired at December 31, 2019. The carrying amount of the GBM) product candidate indication was $2.4 million at
December 31, 2019 and 2018.

At September 30, 2019 and 2018, the Company evaluated its IPR&D of the ovarian cancer indication and concluded that it is not more likely than not that
the asset is impaired. As no other indicators of impairment existed during the fourth quarter of 2019, the Company concluded none of the other IPR&D
assets were impaired at December 31, 2019. The carrying amount of the ovarian cancer indication was $13.3 million at December 31, 2019 and 2018.

Covenants Not to Compete

Pursuant to the EGEN Purchase Agreement, EGEN provided certain covenants (“Covenant Not To Compete”) to the Company whereby EGEN agreed,
during  the  period  ending  on  the  seventh  anniversary  of  the  closing  date  of  the  acquisition  on  June  20,  2014,  not  to  enter  into  any  business,  directly  or
indirectly, which competes with the business of the Company nor will it contact, solicit or approach any of the employees of the Company for purposes of
offering employment. The Covenant Not to Compete which was valued at approximately $1.6 million at the date of the EGEN acquisition has a definitive
life and is amortized on a straight-line basis over its life of 7 years. The Company recognized amortization expense of $227,316 in 2019 and 2018. The
carrying value of the Covenant Not to Compete was $340,976, net of $1,250,238 accumulated amortization, as of December 31, 2019 and $568,292, net of
$1,022,922 accumulated amortization as of December 31, 2018

The purchase price exceeded the estimated fair value of the net assets acquired by approximately $2.0 million which was recorded as Goodwill. Goodwill
represents the difference between the total purchase price for the net assets purchased from EGEN and the aggregate fair values of tangible and intangible
assets acquired, less liabilities assumed. Goodwill is reviewed for impairment at least annually as of our third quarter ended September 30 or sooner if we
believe indicators of impairment exist. As of September 30, 2019, we concluded that the Company’s fair value exceeded its carrying value therefore “it is
not more likely than not” that the Goodwill was impaired. As no other indicators of impairment existed during the fourth quarter of 2019, the Company
concluded it is “not more likely than not” Goodwill was impaired.

On June 27, 2018, the Company entered into a loan agreement with Horizon Technology Finance Corporation (“Horizon”) that provided $10 million in
new capital (the “Horizon Credit Agreement”). The Company drew down $10 million upon closing of the Horizon Credit Agreement on June 27, 2018.
The Company will use the funding provided under the Horizon Credit Agreement for working capital and advancement of its product pipeline.

The  obligations  under  the  Horizon  Credit  Agreement  are  secured  by  a  first-priority  security  interest  in  substantially  all  assets  of  Celsion  other  than
intellectual property assets. The obligations will bear interest at a rate calculated based on one-month LIBOR plus 7.625%. The effective interest rate at
December 31, 2019 was 9.63%. Payments under the loan agreement are interest only for the first twenty-four (24) months after loan closing, followed by a
24-month amortization period of principal and interest through the scheduled maturity date. At its option, the Company can prepay all of the outstanding
principal balance by prepaying the outstanding principal balance and an amount equal to 1-3% of the outstanding principal balance at that time, based on
the amount of time prior to the maturity date of the notes.

The  Horizon  Credit  Agreement  contains  customary  representations,  warranties  and  affirmative  and  negative  covenants  including,  among  other  things,
covenants  that  limit  or  restrict  Celsion’s  ability  to  grant  liens,  incur  indebtedness,  make  certain  restricted  payments,  merge  or  consolidate  and  make
dispositions of assets. Upon the occurrence of an event of default under the Horizon Credit Agreement, the lenders may cease making loans, terminate the
Horizon Credit Agreement, declare all amounts outstanding to be immediately due and payable and foreclose on or liquidate Celsion’s assets that comprise
the  lenders’  collateral.  The  Horizon  Credit  Agreement  specifies  a  number  of  events  of  default  (some  of  which  are  subject  to  applicable  grace  or  cure
periods), including, among other things, non-payment defaults, covenant defaults, a material adverse effect on Celsion or its assets, cross-defaults to other
material indebtedness, bankruptcy and insolvency defaults and material judgment defaults.

As a fee in connection with the Horizon Credit Agreement, Celsion issued Horizon warrants exercisable for a total of 190,114 shares of Celsion’s common
stock (the “Horizon Warrants”) at a per share exercise price of $2.63. The Horizon Warrants are immediately exercisable for cash or by net exercise from
the date of grant and will expire after ten years from the date of grant. Celsion registered the Horizon Warrants on Form S-3 (File No. 333 - 227236) filed
with  the  Securities  and  Exchange  Commission  on  September  7,  2018  and  declared  effective  on  October  10,  2018.  The  Company  valued  the  Horizon
Warrants issued using the Black-Scholes option pricing model and recorded a total of $507,116 as a direct deduction from the debt liability consistent with
the presentation of a debt discount and are being amortized as interest expense using the effective interest method over the life of the loan.

In connection with the Horizon Credit Agreement, the Company incurred financing fees and expenses totaling $175,000 which are recorded and classified
as debt discount. In addition, the Company paid loan origination fees of $100,000 which has been recorded and classified as debt discount. These debt
discount amounts totaling $782,116 are being amortized as interest expense using the effective interest method over the life of the loan. Also, in connection
with each of the Horizon Credit Agreements, the Company is required to pay an end of term charge equal to 4.0% of the original loan amount at time of
maturity. Therefore, these amounts totaling $400,000 are being amortized as interest expense using the effective interest method over the life of the loan.

During 2019, the Company incurred $1,006,760 in interest expense and amortized $386,640 respectively, as interest expense for debt discounts and end of
term charges in connection with the Horizon Credit Agreement. During 2018, the Company incurred $512,872 in interest expense and amortized $199,153
respectively, as interest expense for debt discounts and end of term charges in connection with the Horizon Credit Agreement.

On December 22, 2017, the President of the United States signed into law the Tax Reform Act. The Tax Reform Act significantly changes U.S. tax law by,
among other things, lowering corporate income tax rates, implementing a quasi-territorial tax system, providing a one -time transition toll charge on foreign
earnings, creating a new limitation on the deductibility of interest expenses and modifying the limitation on officer compensation. The Tax Reform Act
permanently reduces the U.S. corporate income tax rate from a maximum of 35% to a flat 21% rate, effective January 1, 2018.

The income tax provision (benefit) for the years ended December 31, 2019 and 2018 consists of the following:

The evaluation of the realizability of such deferred tax assets in future periods is made based upon a variety of factors that affect the Company’s ability to
generate future taxable income, such as intent and ability to sell assets and historical and projected operating performance. As of December 31, 2019, the
Company has established a valuation reserve for its deferred income tax assets other than those related to its New Jersey NOLs. At December 31, 2019,
after its evaluation of its New Jersey NOL’s as discussed more fully below, reduced the valuation reserve and recognized $1.8 million as a deferred tax
asset.  Such  tax  assets  are  available  to  be  recognized  and  benefit  future  periods.  As  of  December  31,  2019,  the  Company  had  net  operating  losses  of
approximately $289 million of which $247 million, if unused, will expire starting in 2023 through 2037. The Federal net operating loss generated for the
year  ended  December  31,  2018  of  approximately  $25.8  million  can  be  carried  forward  indefinitely.  However,  the  deduction  for  net  operating  losses
incurred in tax years beginning after January 1, 2018 is limited to 80% of annual taxable income

During 2019, 2018 and in prior years, the Company performed analyses to determine if there were changes in ownership, as defined by Section 382 of the
Internal  Revenue  Code  that  would  limit  its  ability  to  utilize  certain  net  operating  loss  and  tax  credit  carry  forwards.  The  Company  determined  that  it
experienced ownership changes, as defined by Section 382, in connection with certain common stock offerings in July 2011, February 2013, June 2013,
June 2015, February 2017, June 2017, October 2017 and August 2018. As a result, the utilization of the Company’s federal tax net operating loss carry
forwards  generated  prior  to  the  ownership  changes  are  limited.  As  of  December  31,  2018,  the  Company  has  net  operating  loss  carry  forwards  for  U.S.
federal  and  state  tax  purposes  of  approximately  $233  million,  before  excluding  net  operating  losses  that  have  been  limited  as  a  result  of  Section  382
limitations.  The  annual  limitation  due  to  Section  382  for  net  operating  loss  carry  forward  utilization  is  approximately  $4.2  million  per  year  for
approximately $90 million in net operating loss carry forwards existing at the ownership change occurring in July 2011, approximately $1.4 million per
year for approximately $34 million of additional net operating losses occurring from July 2011 to the ownership change that occurred in February 2013,
approximately $1.5 million per year for approximately $4 million of additional net operating losses occurring from February 2013 to the ownership change
that occurred in June 2013, approximately $1.6 million per year for approximately $40 million of additional net operating losses occurring from June 2013
to the ownership change that occurred in June 2015, approximately $0.3 million per year for approximately $35 million of additional net operating losses
occurring from June 2015 to the ownership change that occurred in February 2017, approximately $0.3 million per year for approximately $7 million of
additional net operating losses occurring from February 2017 to the ownership change that occurred in June 2017, approximately $0.8 million per year for
approximately  $5  million  of  additional  net  operating  losses  occurring  from  June  2017  to  the  ownership  change  that  occurred  in  October  2017,  and
approximately $1.5 million per year for approximately $30 million of additional net operating losses occurring from October 2017 to the ownership change
that  occurred  in  August  2018.  The  utilization  of  these  net  operating  loss  carry  forwards  may  be  further  limited  if  the  Company  experiences  future
ownership changes as defined in Section 382 of the Internal Revenue Code.

Sale of New Jersey Net Operating Losses

During  2019  and  2018,  the  Company  received  approval  to  sell  a  portion  of  the  Company’s  New  Jersey  NOLs  as  part  of  the  Technology  Business  Tax
Certificate Program sponsored by The New Jersey Economic Development Authority. Under the program, emerging biotechnology companies with unused
NOLs and unused research and development credits are allowed to sell these benefits to other companies. During the first quarter of 2020, the Company
entered into an agreement to sell these approved portion of these New Jersey NOL’s for $1.8 million. At December 31, 2019, the Company evaluated the
valuation reserve for its tax net operating losses associated with its New Jersey NOLs and reduced the valuation reserve and recognized $1.8 million as a
deferred income tax asset and an income tax benefit. The Company expects to complete the sale of these net operating losses in the second quarter of 2020.
In 2018, the Company completed the sale of a portion of its New Jersey net operating losses totaling approximately $11.1 million for net proceeds of $10.4
million in December 2018. The Company has approximately $2.1 million in future tax benefits remaining under the NOL Program for future years.

10. STOCKHOLDERS’ EQUITY

In September 2018, the Company filed with the SEC a $75 million shelf registration statement on Form S-3 (the 2018 Shelf Registration Statement) (File
No. 333-227236) that allows the Company to issue any combination of common stock, preferred stock or warrants to purchase common stock or preferred
stock. This shelf registration was declared effective on October 12, 2018 and will expire three years from that date.

Aspire Purchase Agreement

On August  31,  2018,  we  entered  into  a  common  stock  purchase  agreement  (the  “2018  Aspire  Purchase  Agreement”)  with  Aspire  Capital  Fund,  LLC
(“Aspire  Capital”)  which  provides  that,  upon  the  terms  and  subject  to  the  conditions  and  limitations  set  forth  therein,  Aspire  Capital  is  committed  to
purchase up to an aggregate of $15.0 million of shares of the Company’s common stock over the 24-month term of the 2018 Aspire Purchase Agreement.
On  October  12,  2018,  the  Company  filed  with  the  SEC  a  prospectus  supplement  to  the  2018  Shelf  Registration  Statement  registering  all  the  shares  of
common stock that may be offered to Aspire Capital from time to time.

Under  the  2018  Aspire  Purchase  Agreement,  on  any  trading  day  selected  by  the  Company,  the  Company  has  the  right,  in  its  sole  discretion,  to  present
Aspire  Capital  with  a  purchase  notice  (each,  a  “Purchase  Notice”),  directing  Aspire  Capital  (as  principal)  to  purchase  up  to  100,000  shares  of  the
Company’s  common  stock  per  business  day,  up  to  $15.0  million  of  the  Company’s  common  stock  in  the  aggregate  at  a  per  share  price  (the  “Purchase
Price”) equal to the lesser of:

●

●

the lowest sale price of the Company’s common stock on the purchase date; or

the arithmetic average of the three (3) lowest closing sale prices for the Company’s common stock during the ten (10) consecutive trading days
ending on the trading day immediately preceding the purchase date.

The Company and Aspire Capital also may mutually agree to increase the number of shares that may be sold to as much as an additional 2,000,000 shares
per business day.

In addition, on any date on which the Company submits a Purchase Notice to Aspire Capital in an amount equal to at least 100,000 shares, the Company
also has the right, in its sole discretion, to present Aspire Capital with a volume-weighted average price purchase notice (each, a “VWAP Purchase Notice”)
directing Aspire Capital to purchase an amount of stock equal to up to 30% of the aggregate shares of the Company’s common stock traded on its principal
market on the next trading day (the “VWAP Purchase Date”), subject to a maximum number of shares the Company may determine. The purchase price per
share  pursuant  to  such  VWAP  Purchase  Notice  is  generally  97%  of  the  volume-weighted  average  price  for  the  Company’s  common  stock  traded  on  its
principal market on the VWAP Purchase Date.

The Purchase Price will be adjusted for any reorganization, recapitalization, non-cash dividend, stock split, or other similar transaction occurring during the
period(s) used to compute the Purchase Price. The Company may deliver multiple Purchase Notices and VWAP Purchase Notices to Aspire Capital from
time to time during the term of the Purchase Agreement, so long as the most recent purchase has been completed.

There are no trading volume requirements or restrictions under the 2018 Aspire Purchase Agreement, and the Company will control the timing and amount
of  sales  of  the  Company’s  common  stock  to  Aspire  Capital.  Aspire  Capital  has  no  right  to  require  any  sales  by  the  Company  but  is  obligated  to  make
purchases from the Company as directed by the Company in accordance with the 2018 Aspire Purchase Agreement. There are no limitations on use of
proceeds, financial or business covenants, restrictions on future funding, rights of first refusal, participation rights, penalties or liquidated damages in the
Aspire Purchase Agreement. In consideration for entering into the 2018 Aspire Purchase Agreement, concurrently with the execution of the 2018 Aspire
Purchase  Agreement,  the  Company  issued  to  Aspire  Capital  164,835  shares  of  the  Company’s  common  stock  (the  “2018  Commitment  Shares”).  The
Company’s policy is to record specific incremental costs directly attributable to an offering as a charge against the gross proceeds, if any, when the offering
becomes effective. The 2018 Commitment Shares valued at $450,000 were recorded in September 2018 as costs of equity financing and charged against
additional paid-in capital. The 2018 Aspire Purchase Agreement may be terminated by the Company at any time, at its discretion, without any cost to the
Company. Aspire Capital has agreed that neither it nor any of its agents, representatives and affiliates shall engage in any direct or indirect short-selling or
hedging  of  the  Company’s  common  stock  during  any  time  prior  to  the  termination  of  the  2018  Aspire  Purchase  Agreement.  Any  proceeds  from  the
Company receives under the 2018 Aspire Purchase Agreement are expected to be used for working capital and general corporate purposes. During 2018,
the Company sold and issued an aggregate of 100,000 shares under the 2018 Aspire Purchase Agreement, receiving approximately $0.2 million. During
2019, the Company sold and issued an aggregate of 3.3 million shares under the 2018 Aspire Purchase Agreement, receiving approximately $6.3 million.
As a result of the Company and Aspire Capital entering into a new purchase agreement on October 28, 2019 discussed in the next paragraph, the 2018
Aspire Purchase Agreement was terminated.

On  October  28,  2019,  Company,  entered  into  a  new  common  stock  purchase  agreement  (the  “2019  Aspire  Purchase  Agreement”)  with  Aspire  Capital
which  provides  that,  upon  the  terms  and  subject  to  the  conditions  and  limitations  set  forth  therein,  Aspire  Capital  is  committed  to  purchase  up  to  an
aggregate of $10.0 million of shares of the Company’s common stock over the 24-month term of the 2019 Aspire Purchase Agreement. Concurrently with
entering into the 2019 Aspire Purchase Agreement, the Company also entered into a registration rights agreement with Aspire Capital (the “Registration
Rights Agreement”), in which the Company agreed to file one or more registration statements, as permissible and necessary to register under the Securities
Act of 1933, as amended (the “Securities Act”), registering the sale of the shares of the Company’s common stock that have been and may be issued to
Aspire Capital under the 2019 Aspire Purchase Agreement. On November 8, 2019, the Company filed with the SEC a Registration Statement on Form S-1
registering all the shares of common stock that may be offered to Aspire Capital from time to time under the 2019 Aspire Purchase Agreement.

The terms and conditions pursuant to the 2019 Aspire Purchase Agreement are substantially similar to the 2018 Aspire Purchase Agreement and the more
significant terms are restated as follows:

● Under the  terms  of  the  2019  Aspire  Purchase  Agreement,  on  any  trading  day  selected  by  the  Company,  the  Company  has  the  right,  in  its  sole
discretion, to present Aspire Capital with a Purchase Notice, directing Aspire Capital to purchase up to 100,000 shares of the Company’s common
stock per business day, up to $10.0 million of the Company’s common stock in the aggregate at a per share Purchase Price equal to the lesser of:

● the lowest sale price of the Company’s common stock on the purchase date; or

● the arithmetic average of the three (3) lowest closing sale prices for the Company’s common stock during the ten (10) consecutive trading

days ending on the trading day immediately preceding the purchase date.

● In addition, on any date on which the Company submits a Purchase Notice to Aspire Capital in an amount of 100,000 shares, the Company also
has the right, in its sole discretion, to present Aspire Capital with a VWAP Purchase Notice directing Aspire Capital to purchase an amount of
stock equal to up to 30% of the aggregate shares of the Company’s common stock traded on the VWAP Purchase Date, subject to a maximum
number of shares the Company may determine. The purchase price per share pursuant to such VWAP Purchase Notice is generally 97% of the
volume-weighted average price for the Company’s common stock traded on its principal market on the VWAP Purchase Date.

● In consideration for entering into the 2019 Aspire Purchase Agreement, the Company issued to Aspire Capital 100,000 shares of the Company’s
common stock (the “2019 Commitment Shares”). The Company’s policy is to record specific incremental costs directly attributable to an offering
as a charge against the gross proceeds, if any, when the offering becomes effective. The 2019 Commitment Shares will be fair valued and recorded
in October 2019 as costs of equity financing and charged against additional paid-in capital.

● All other rights, responsibilities and conditions of the 2019 Aspire Purchase Agreement remain the same as the prior agreement in 2018.

During 2019, the Company sold and issued an aggregate of 0.5 million shares under the 2019 Aspire Purchase Agreement, receiving approximately $0.7
million. Subsequent to December 31, 2019 and through March 5, 2020 when the Company delivered notice to Aspire terminating the 2019 Aspire Purchase
Agreement,  the  Company  sold  1.0  million  shares  of  common  stock  under  the  Aspire  Purchase  Agreement,  receiving  approximately  $1.6  million  in
additional gross proceeds.

Capital on DemandTM Sales Agreement

On  December  4,  2018,  the  Company  entered  into  a  Capital  on  DemandTM  Sales  Agreement  (the  “Capital  on  Demand  Agreement”)  with  JonesTrading
Institutional Services LLC, as sales agent (“JonesTrading”), pursuant to which the Company may offer and sell, from time to time, through JonesTrading
shares of Common Stock having an aggregate offering price of up to $16.0 million. The Company intends to use the net proceeds from the offering, if any,
for general corporate purposes, including research and development activities, capital expenditures and working capital.

The Company is not obligated to sell any Common Stock under the Capital on Demand Agreement and, subject to the terms and conditions of the Capital
on Demand Agreement, JonesTrading will use commercially reasonable efforts, consistent with its normal trading and sales practices and applicable state
and  federal  law,  rules  and  regulations  and  the  rules  of  The  Nasdaq  Capital  Market,  to  sell  Common  Stock  from  time  to  time  based  upon  Celsion’s
instructions, including any price, time or size limits or other customary parameters or conditions the Company may impose. Under the Capital on Demand
Agreement, JonesTrading may sell Common Stock by any method deemed to be an “at the market offering” as defined in Rule 415 promulgated under the
Securities Act of 1933, as amended.

The Capital on Demand Agreement will terminate upon the earlier of (i) the sale of all shares of our common stock subject to the Sales Agreement, and (ii)
the termination of the Capital on Demand Agreement by JonesTrading or Celsion. The Capital on Demand Agreement may be terminated by JonesTrading
or the Company at any time upon 10 days’ notice to the other party, or by JonesTrading at any time in certain circumstances, including the occurrence of a
material adverse change in the Company.

The Company will pay JonesTrading a commission of 3.0% of the aggregate gross proceeds from each sale of Common Stock and has agreed to provide
JonesTrading with customary indemnification and contribution rights.

The  Shares  will  be  issued  pursuant  to  Celsion’s  previously  filed  and  effective  Registration  Statement  on  Form  S-3  (File  No.  333-227236),  the  base
prospectus dated October 12, 2018, filed as part of such Registration Statement, and the prospectus supplement dated December 4, 2018, filed by Celsion
with the Securities and Exchange Commission. During 2019, the Company sold and issued an aggregate of 0.5 million shares under the Capital on Demand
Agreement, receiving approximately $1.0 million in gross proceeds. The Company did not sell any shares under the Capital on Demand Agreement as of
December 31, 2018. As of December 31, 2019, the Company has approximately $15 million available under the Capital on Demand Agreement.

Controlled Equity Offering

On February 1, 2013, the Company entered into a Controlled Equity Offering SM Sales Agreement (the “ATM Agreement”) with Cantor Fitzgerald & Co.,
as  sales  agent  (“Cantor”),  pursuant  to  which  Celsion  could  offer  and  sell,  from  time  to  time,  through  Cantor,  shares  of  our  common  stock  having  an
aggregate offering price of up to $25.0 million (the “ATM Shares”) pursuant to the 2015 Shelf Registration Statement. Under the ATM Agreement, Cantor
may sell ATM Shares by any method deemed to be an “at-the-market” offering as defined in Rule 415 promulgated under the Securities Act of 1933, as
amended,  including  sales  made  directly  on  The  Nasdaq  Capital  Market,  on  any  other  existing  trading  market  for  our  common  stock  or  to  or  through  a
market maker. On October 10, 2018, the Company delivered notice to Cantor terminating the ATM effective as of October 20, 2018. The Company has no
further obligations under the Sales Agreement. During 2018, the Company received approximately $1.2 million in proceeds from the sale of 0.5 million
shares of common stock under the ATM Agreement. From February 1, 2013 through September 30, 2018, the Company sold and issued an aggregate of
1,784,396 shares of common stock under the ATM Agreement, receiving approximately $12.8 million in gross proceeds.

Registered Direct Offering

On February 27, 2020, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with several institutional investors, pursuant to which
we agreed to issue and sell, in a registered direct offering (the “February 2020 Offering”), an aggregate of 4,571,428 shares (the “Shares”) of our common
stock at an offering price of $1.05 per share for gross proceeds of approximately $4.8 million before the deduction of the Placement Agent fees and offering
expenses.  The  Shares  were  offered  by  the  Company  pursuant  to  a  registration  statement  on  Form  S-3  (File  No.  333-227236).  The  Purchase  Agreement
contains customary representations, warranties and agreements by the Company and customary conditions to closing. In a concurrent private placement
(the  “Private  Placement”),  the  Company  agreed  to  issue  to  the  investors  that  participated  in  the  Offering,  for  no  additional  consideration,  warrants,  to
purchase up to 2,971,428 shares of Common Stock (the “Original Warrants”). The Original Warrants were initially exercisable six months following their
and were set to expire on the five-year anniversary of such initial exercise date. The Warrants had an exercise price of $1.15 per share subject to adjustment
as provided therein. On March 12, 2020 the Company entered into private exchange agreements (the “Exchange Agreements”) with holders the Warrants.
Pursuant to the Exchange Agreements, in return for a higher exercise price of $1.24 per share of Common Stock, the Company issued new warrants to the
Investors to purchase up to 3,200,000 shares of Common Stock (the “Exchange Warrants”) in exchange for the Original Warrants. The Exchange Warrants,
like the Original Warrants, are initially exercisable six months following their issuance (the “Initial Exercise Date”) and expire on the five-year anniversary
of  their  Initial  Exercise  Date.  Other  than  having  a  higher  exercise  price,  different  issue  date,  Initial  Exercise  Date  and  expiration  date,  the  terms  of  the
Exchange Warrants are identical to those of the Original Warrants.

11. STOCK-BASED COMPENSATION

The Company has long-term compensation plans that permit the granting of equity-based awards in the form of stock options, restricted stock, restricted
stock units, stock appreciation rights, other stock awards, and performance awards.

At the 2018 Annual Stockholders Meeting of the Company held on May 15, 2018, stockholders approved the Celsion Corporation 2018 Stock Incentive
Plan (the “2018 Plan”). The 2018 Plan, as adopted, permits the granting of 2,700,000 shares of Celsion common stock as equity awards in the form of
incentive  stock  options,  nonqualified  stock  options,  restricted  stock,  restricted  stock  units,  stock  appreciation  rights,  other  stock  awards,  performance
awards, or in any combination of the foregoing. At the 2019 Annual Stockholders Meeting of the Company held on May 14, 2019, stockholders approved
an amendment to the 2018 Plan whereby the Company increased the number of common stock shares available by 1,200,000 to a total of 3,900,000 under
the 2018 Plan, as amended. Prior to the adoption of the 2018 Plan, the Company had maintained the Celsion Corporation 2007 Stock Incentive Plan (the
“2007 Plan”).

The Company has issued stock awards to employees and directors in the form of stock options and restricted stock. Options are generally granted with
strike prices equal to the fair market value of a share of Celsion common stock on the date of grant. Incentive stock options may be granted to purchase
shares of common stock at a price not less than 100% of the fair market value of the underlying shares on the date of grant, provided that the exercise price
of any incentive stock option granted to an eligible employee owning more than 10% of the outstanding stock of Celsion must be at least 110% of such fair
market value on the date of grant. Only officers and key employees may receive incentive stock options.

Option and restricted stock awards vest upon terms determined by the Compensation Committee of the Board of Directors and are subject to accelerated
vesting  in  the  event  of  a  change  of  control  or  certain  terminations  of  employment.  The  Company  issues  new  shares  to  satisfy  its  obligations  from  the
exercise of options or the grant of restricted stock awards.

On September 28, 2018, and again on February 19, 2019, the Compensation Committee of the Board of Directors approved the grant of (i) inducement
stock  options  (the  “Inducement  Option  Grants”)  to  purchase  a  total  of  164,004  and  140,004  shares  of  Celsion  common  stock,  respectively  and  (ii)
inducement restricted stock awards (the “Inducement Stock Grants”) totaling 19,000 and 13,000 shares of Celsion common stock to five new employees
collectively.  Each  award  has  a  grant  date  of  the  date  of  grant.  Each  Inducement  Option  Grant  has  an  exercise  price  per  share  equal  to  $2.77  and  $2.18
which represents the closing price of Celsion’s common stock as reported by Nasdaq on September 28, 2018 and February 19, 2019, respectively. Each
Inducement Option Grant will vest over three years, with one-third vesting on the one-year anniversary of the employee’s first day of employment with the
Company  and  one-third  vesting  on  the  second  and  third  anniversaries  thereafter,  subject  to  the  new  employee’s  continued  service  relationship  with  the
Company on each such date. Each Inducement Option Grant has a ten-year term and is subject to the terms and conditions of the applicable stock option
agreement. Each of Inducement Stock Grant will vest on the one-year anniversary of the employee’s first day of employment with the Company and are
subject  to  the  new  employee’s  continued  service  relationship  with  the  Company  through  such  date  and  is  subject  to  the  terms  and  conditions  of  the
applicable restricted stock agreement.

As  of  December  31,  2019,  there  were  a  total  of  4,580,893  shares  of  Celsion  common  stock  reserved  for  issuance  under  the  2018  Plan,  which  were
comprised  of  4,130,886  shares  of  Celsion  common  stock  subject  to  equity  awards  previously  granted  under  the  2018  Plan  and  2007  Plan  and  450,007
shares of Celsion common stock available for future issuance under the 2018 Plan. As of December 31, 2019, there were a total of 210,006 of Celsion
common stock subject to outstanding inducement awards.

Total  compensation  cost  related  to  stock  options  and  restricted  stock  awards  was  approximately  $2.3  million  and  $4.6  million  during  2019,  and  2018,
respectively.  Of  these  amounts,  $0.9  million  and  $1.5  million  was  charged  to  research  and  development  during  2019  and  2018,  respectively,  and  $1.4
million and $3.1 million was charged to general and administrative expenses during 2019 and 2018, respectively.

The fair values of stock options granted were estimated at the date of grant using the Black-Scholes option pricing model. The Black-Scholes model was
originally developed for use in estimating the fair value of traded options, which have different characteristics from Celsion’s stock options. The model is
also sensitive to changes in assumptions, which can materially affect the fair value estimate. The Company used the following assumptions for determining
the fair value of options granted under the Black-Scholes option pricing model:

Risk-free interest rate
Expected volatility
Expected life (in years)
Expected dividend yield

Year Ended December 31,

2019

2.82 to 3.02% 
101.3 – 106.2% 
7.5 to 9.3 

0.0% 

2018

2.82 to 3.02%
99.9 - 102.1%
8.5 to 10 

0.0%

Expected volatilities utilized in the model are based on historical volatility of the Company’s stock price. As of December 31, 2019, there was $1.6 million
of  total  unrecognized  compensation  cost  related  to  non-vested  stock-based  compensation  arrangements.  That  cost  is  expected  to  be  recognized  over  a
weighted-average period of 1.1 years.

12. EARN-OUT MILESTONE LIABILITY

The  total  aggregate  purchase  price  for  the  EGEN  Acquisition  included  potential  future  Earn-out  Payments  contingent  upon  achievement  of  certain
milestones.  The  difference  between  the  aggregate  $30.4  million  in  future  Earn-out  Payments  and  the  $13.9  million  included  in  the  fair  value  of  the
acquisition consideration at June 20, 2014 was based on the Company’s risk-adjusted assessment of each milestone (10% to 67%) and utilizing a discount
rate based on the estimated time to achieve the milestone (1.5 to 2.5 years). The earn-out milestone liability will be fair valued at the end of each quarter
and any change in their value will be recognized in the financial statements.

On  March  28,  2019,  the  Company  and  EGWU,  Inc,  entered  into  the  Amended  Asset  Purchase  Agreement.  Pursuant  to  the  Amended  Asset  Purchase
Agreement, payment of the earnout milestone liability related to the Ovarian Cancer Indication of $12.4 million has been modified. The Company has the
option to make the payment as follows:

$7.0 million in cash within 10 business days of achieving the milestone; or

a)
b) $12.4 million in cash, common stock of the Company, or a combination of either, within one year of achieving the milestone.

The Company provided EGWU, Inc. 200,000 warrants to purchase common stock at a strike price of $0.01 per warrant share as consideration for entering
into this amended agreement. The warrant shares have no expiration and were fair valued at $2.00 using the closing price of a share of Celsion stock on the
date of issuance offset by the exercise price and recorded as a non-cash expense in the income statement and were classified as equity on the balance sheet.

At December 31, 2019, the Company fair valued the earn-out milestone liability at $5.7 million and recognized a non-cash gain of $3.2 million during 2019
as a result of the change in the fair value of earn-out milestone liability of $8.9 million at December 31, 2018. In assessing the earnout milestone liability at
December 31, 2019, the Company fair valued each of the two payment options per the Amended Asset Purchase Agreement and weighted them at 80% and
20% probability for the $7.0 million and the $12.4 million payments, respectively.

At December 31, 2018, the Company fair valued the earn-out milestone liability at $8.9 million and recognized a non-cash gain of $3.6 million during 2018
as a result of the change in the fair value of earn-out milestone liability of $12.5 million at December 31, 2017. Included in the non-cash gain during 2018,
was  the  reduction  of  the  liability  by  $3.9  million  during  the  third  quarter  of  2017  related  to  the  write  down  of  one  of  the  in-process  research  and
development assets (see Note 5) as the Company believes there is a de minimis probability of the payout of the related earn-out milestone liabilities. The
fair value of the remaining earn-out milestone liabilities at December 31, 2018 was based on the Company’s risk-adjusted assessment of each milestone
(80%) utilizing a discount rate based on the estimated time to achieve the milestone (1.25 years).

15. LEASES

In  2011,  the  Company  executed  a  lease  (the  “Lease”)  with  Brandywine  Operating  Partnership,  L.P.  (Brandywine),  a  Delaware  limited  partnership  for  a
10,870 square foot premises located in Lawrenceville, New Jersey and relocated its offices to Lawrenceville, New Jersey from Columbia, Maryland. The
Lease had an initial term of 66 months. In late 2015, Lenox Drive Office Park LLC, purchased the real estate and office building and assumed the Lease.
This Lease was set to expire on April 30, 2017. In April 2017, the Company and the landlord amended the Lease effective May 1, 2017. The 1st Lease
Amendment  extended  the  term  of  the  agreement  for  an  additional  64  months,  reduced  the  premises  to  7,565  square  feet,  reduced  the  monthly  rent  and
provided four months free rent. The monthly rent ranged from approximately $18,900 in the first year to approximately $20,500 in the final year of the 1st
Lease  Amendment.  The  Company  also  had  a  one-time  option  to  cancel  the  lease  as  of  the  40th  month  after  the  commencement  date  of  the  1st  Lease
Amendment and must provide the landlord notice by the 28th month of the lease. Effective January 9, 2019, the Company amended the current terms of the
1st  Lease  Amendment  to  increase  the  size  of  the  premises  by  2,285  square  feet  to  9,850  square  feet  and  also  extended  the  lease  term  by  one  year  to
September 1, 2023. In conjunction with this 2nd Lease Amendment, we agreed to modify our one-time option to cancel the lease as of the end of August
2021 and we must provide notice to the landlord by the end of August 2020. The monthly rent will range from approximately $25,035 in the first year to
approximately $27,088 in the final year of the 2nd Lease Amendment.

In connection with the EGEN Asset Purchase Agreement in June 2014, the Company assumed the existing lease with another landlord for an 11,500 square
foot premises located in Huntsville Alabama. In January 2018, the Company and the Huntsville landlord entered into a new 60-month lease which reduced
the premises to 9,049 square feet with rent payments of approximately $18,100 per month.

As  previously  mentioned  in  Note  4,  we  adopted  ASC  Topic  842  on  January  1,  2019  using  the  modified  retrospective  transition  method  for  all  lease
arrangements at the beginning of the period of adoption. Results for reporting periods beginning January 1, 2019 are presented under ASC 842, while prior
period  amounts  were  not  adjusted  and  continue  to  be  reported  in  accordance  with  our  historic  accounting  under  Topic  840,  Leases.  The  standard  had  a
material impact on our Consolidated Condensed Balance Sheet but had no impact on our consolidated net earnings and cash flows. The most significant
impact of adopting ASC Topic 842 was the recognition of the right-of-use (ROU) asset and lease liabilities for operating leases, which are presented in the
following three-line items on the Consolidated Condensed Balance Sheet: (i) operating lease right-of-use asset; (ii) current operating lease liabilities; and
(iii) operating lease liabilities. Therefore, on date of adoption of ASC Topic 842, the Company recognized a ROU asset of $1.4 million, operating lease
liabilities,  current  and  non-current  collectively,  of  $1.5  million  and  reduced  other  liabilities  by  approximately  $0.1  million.  We  elected  the  package  of
practical expedients for leases that commenced before the effective date of ASC Topic 842 whereby we elected to not reassess the following: (i) whether
any expired or existing contracts contain leases; (ii) the lease classification for any expired or existing leases; and (iii) initial direct costs for any existing
leases. In addition, we have lease agreements with lease and non-lease components, and we have elected the practical expedient for all underlying asset
classes and account for them as a single lease component. We have no finance leases. We determine if an arrangement is a lease at inception. We have
operating leases for office space and research and development facilities. Neither of our leases include options to renew, however, one contains an option
for early termination. We considered the option of early termination in measurement of right-of-use assets and lease liabilities and we determined it is not
reasonably  certain  to  be  terminated.  In  connection  with  the  2nd  Lease  Amendment  for  the  New  Jersey  office  lease  in  January  2019,  the  Company
considered this as one modified lease and not as two separate leases. Therefore, in January 2019, the Company determined this lease was an operating lease
and remeasured the ROU asset and lease liability. Therefore, the Company increased the ROU asset and operating lease liabilities by $0.4 million to $1.8
million and $1.9 million, respectively.

Following is a table of the lease payments and maturity of our operating lease liabilities as of December 31, 2019:

16. COMMITMENTS AND CONTINGENCIES

On  September  20,  2019,  a  purported  stockholder  of  the  Company  filed  a  derivative  and  putative  class  action  lawsuit  against  the  Company  and  certain
officers and directors (the “Shareholder Action”). The Shareholder Action alleges breaches of fiduciary duty in connection with the shareholder approval
process  associated  with  the  2018  Stock  Incentive  Plan.  The  matter  is  in  the  early  stages  and  the  ultimate  outcome  of  this  matter  is  not  currently
determinable at this time.

On  November  10,  1999,  the  Company  entered  into  a  license  agreement  with  Duke  University  (“Duke”)  under  which  the  Company  received  worldwide
exclusive rights (subject to certain exceptions) to commercialize and use Duke’s thermally sensitive liposome technology. The license agreement contains
annual royalty and minimum payment provisions due on net sales. The agreement also required milestone-based royalty payments measured by various
events,  including  product  development  stages,  FDA  applications  and  approvals,  foreign  marketing  approvals  and  achievement  of  significant  sales.
However, in lieu of such milestone-based cash payments, Duke agreed to accept shares of the Company’s common stock to be issued in installments at the
time each milestone payment is due, with each installment of shares to be calculated at the average closing price of the common stock during the 20 trading
days prior to issuance.

The total number of shares issuable to Duke under these provisions is subject to adjustment in certain cases, and Duke has piggyback registration rights for
public offerings taking place more than one year after the effective date of the license agreement. On January 31, 2003, the Company issued 253,691 shares
of common stock to Duke University valued at $2.2 million as payment for milestone-based royalties under this license agreement. An amendment to the
Duke  license  agreement  contains  certain  development  and  regulatory  milestones,  and  other  performance  requirements  that  the  Company  has  met  with
respect to the use of the licensed technologies. The Company will be obligated to make royalty payments based on sales to Duke upon commercialization,
until  the  last  of  the  Duke  patents  expire.  For  the  years  ended  December  31,  2019  and  2018,  the  Company  has  not  incurred  any  expense  under  this
agreement and will not incur any future liabilities until commercial sales commence.

Under the November 1999 license agreement with Duke, the Company has rights to the thermally sensitive liposome technology, including Duke’s U.S.
patents covering the technology as well as all foreign counter parts and related pending applications. Foreign counterpart applications have been issued in
the EU, Hong Kong, Australia and Canada and have been allowed in Japan. The EU patent has been validated in Austria, Belgium, France, Germany, Great
Britain, Italy, Luxembourg, Monaco, Spain and Switzerland. In addition, the Duke license agreement provides the Company with rights to multiple issued
and  pending  U.S.  patents  related  to  the  formulation,  method  of  making  and  use  of  heat  sensitive  liposomes.  The  Company’s  rights  under  the  license
agreement with Duke extend for the life of the last-to-expire of the licensed patents.

The Company has licensed from Valentis, CA certain global rights covering the use of pegylation for temperature sensitive liposomes.

In addition to the rights available to the Company under completed or pending license agreements, the Company is actively pursuing patent protection for
technologies developed by the Company. Among these patents is a family of pending US and international patent applications which seek to protect the
Company’s proprietary method of storing ThermoDox® which is critical for worldwide distribution channels.

technology. Similarly, the Company cannot guarantee that technology rights licensed to it by others will not be successfully challenged or circumvented by
third parties, or that the rights granted will provide the Company with adequate protection.

18. TECHNOLOGY DEVELOPMENT AND LICENSING AGREEMENTS

On  May  7,  2012,  the  Company  entered  into  a  long-term  commercial  supply  agreement  with  Zhejiang  Hisun  Pharmaceutical  Co.  Ltd.  (Hisun)  for  the
production  of  ThermoDox®  in  the  China  territory.  In  accordance  with  the  terms  of  the  agreement,  Hisun  will  be  responsible  for  providing  all  of  the
technical  and  regulatory  support  services,  including  the  costs  of  all  technical  transfer,  registration  and  bioequivalence  studies,  technical  transfer  costs,
Celsion consultative support costs and the purchase of any necessary equipment and additional facility costs necessary to support capacity requirements for
the manufacture of ThermoDox®. Celsion will repay Hisun for the aggregate amount of these development costs and fees commencing on the successful
completion of three registration batches of ThermoDox®. Hisun is also obligated to certain performance requirements under the agreement. The agreement
will initially be limited to a percentage of the production requirements of ThermoDox® in the China territory with Hisun retaining an option for additional
global  supply  after  local  regulatory  approval  in  the  China  territory.  In  addition,  Hisun  will  collaborate  with  Celsion  around  the  regulatory  approval
activities for ThermoDox® with the China State Food and Drug Administration (CHINA FDA).

On  January  18,  2013,  we  entered  into  a  technology  development  contract  with  Hisun,  pursuant  to  which  Hisun  paid  us  a  non-refundable  research  and
development fee of $5 million to support our development of ThermoDox ® in mainland China, Hong Kong and Macau (the China territory). Following
our  announcement  on  January  31,  2013  that  the  HEAT  study  failed  to  meet  its  primary  endpoint,  Celsion  and  Hisun  have  agreed  that  the  Technology
Development Contract entered into on January 18, 2013 will remain in effect while the parties continue to collaborate and are evaluating the next steps in
relation to ThermoDox®, which include the sub-group analysis of patients in the Phase III HEAT Study for the hepatocellular carcinoma clinical indication
and other activities to further the development of ThermoDox ® for the Greater China market. The $5.0 million received as a non-refundable payment from
Hisun in the first quarter 2013 has been recorded to deferred revenue and will continue to be amortized over the 10 -year term of the agreement, until such
time as the parties find a mutually acceptable path forward on the development of ThermoDox ® based on findings of the ongoing post-study analysis of
the HEAT Study data.

19. SUBSEQUENT EVENTS

As more fully discussed in Note 10, the Company sold 4.6 million shares of common stock for gross proceeds of $4.8 million under the February 2020
Offering. On March 5, 2020, the Company also terminated the 2019 Aspire Purchase Agreement.

Preferred Stock

Undesignated Preferred Stock

Pursuant to our certificate of incorporation, our board of directors has the authority, without further action by the stockholders (unless such stockholder
action is required by applicable law or NASDAQ rules), to designate and issue shares of preferred stock in one or more series, to establish from time to
time  the  number  of  shares  to  be  included  in  each  such  series,  to  fix  the  designations,  powers  (including  voting),  privileges,  preferences  and  relative
participating, optional or other rights, if any, of the shares of each such series and the qualifications, limitations or restrictions thereof and to increase or
decrease the number of shares of any such series, but not below the number of shares of such series then outstanding.

We will fix the designations, powers (including voting), privileges, preferences and relative participating, optional or other rights, if any, of the preferred
stock of each series, as well as the qualifications, limitations or restrictions thereof, in the certificate of designation relating to that series. We will file as an
exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of
any certificate of designation that describes the terms of the series of preferred stock we are offering before the issuance of that series of preferred stock.
This description will include:

● the title and stated value;

● the number of shares we are offering;

● the liquidation preference per share;

● the purchase price;

● the dividend rate, period and payment date and method of calculation for dividends;

● whether dividends will be cumulative or non-cumulative and, if cumulative, the date from which dividends will accumulate;

● the procedures for any auction or remarketing, if any;

● the provisions for a sinking fund, if any;

●

the provisions  for  redemption  or  repurchase,  if  applicable,  and  any  restrictions  on  our  ability  to  exercise  those  redemption  and  repurchase
rights;

● any listing of the preferred stock on any securities exchange or market;

● whether the preferred stock will be convertible into or exchangeable for other securities and, if applicable, the conversion price, or how it will

be calculated, and the conversion period;

● restrictions on transfer, sale or other assignment, if any;

● liability as to further calls or to assessment by the Company, if any;

The DGCL provides that the holders of preferred stock will have the right to vote separately as a class or, in some cases, as a series on an amendment to our
certificate  of  incorporation  if  the  amendment  would  change  the  par  value  or,  unless  our  certificate  of  incorporation  provides  otherwise,  the  number  of
authorized shares of the class or the powers, preferences or special rights of the class or series so as to adversely affect the class or series, as the case may
be. This right is in addition to any voting rights that may be provided in the applicable certificate of designation.

Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other
rights of the holders of our common stock or other securities. Preferred stock could be issued quickly with terms designed to delay or prevent a change in
control of our company or make removal of management more difficult. Additionally, the issuance of preferred stock may have the effect of decreasing the
market price of our common stock.

Anti-Takeover  Considerations  and  Special  Provisions  of  Our  Certificate  of  Incorporation,  Our  Bylaws  and  the  Delaware  General  Corporation
Law

Certificate of Incorporation and Bylaws

A  number  of  provisions  of  our  certificate  of  incorporation  and  bylaws  concern  matters  of  corporate  governance  and  the  rights  of  our  stockholders.
Provisions that grant our board of directors the ability to issue shares of preferred stock and to set the voting rights, preferences and other terms thereof may
discourage takeover attempts that are not first approved by our board of directors, including takeovers that may be considered by some stockholders to be
in their best interests, such as those attempts that might result in a premium over the market price for the shares held by stockholders. Certain provisions
could delay or impede the removal of incumbent directors even if such removal would be beneficial to our stockholders, such as the classification of our
board of directors and the lack of cumulative voting.

Since our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders
or another party to effect a change in management.

These provisions may have the effect of deterring hostile takeovers or delaying changes in our control or in our management. These provisions are intended
to enhance the likelihood of continued stability in the composition of our board of directors and in the policies they implement and to discourage certain
types  of  transactions  that  may  involve  an  actual  or  threatened  change  of  our  control.  These  provisions  are  designed  to  reduce  our  vulnerability  to  an
unsolicited acquisition proposal. The provisions also are intended to discourage certain tactics that may be used in proxy fights. However, such provisions
could  have  the  effect  of  discouraging  others  from  making  tender  offers  for  our  shares  and,  as  a  consequence,  they  also  may  inhibit  fluctuations  in  the
market price of our shares that could result from actual or rumored takeover attempts.

These provisions also could discourage or make more difficult a merger, tender offer or proxy contest, even if they could be favorable to the interests of
stockholders, and could potentially depress the market price of our common stock. Our board of directors believes that these provisions are appropriate to
protect our interests and the interests of our stockholders.

Classification of Board; No Cumulative Voting.

Our certificate of incorporation and bylaws provide for our board of directors to be divided into three classes, with staggered three-year terms. Only one
class of directors is elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year
terms. Because our stockholders do not have cumulative voting rights, our stockholders representing a majority of the shares of common stock outstanding
will be able to elect all of our directors due to be elected at each annual meeting of our stockholders.

 
 
 
 
 
 
 
 
 
 
 
 
 
Meetings of and Actions by Stockholders.

Our bylaws provide that annual meetings of our stockholders may take place at the time and place designated by our board of directors. A special meeting
of our stockholders may be called at any time by our board of directors, the chairman of our board of directors or the president. Our bylaws provide that (i)
our board of directors can fix separate record dates for determining stockholders entitled to receive notice of a stockholder meeting and for determining
stockholders entitled to vote at the meeting; (ii) we may hold a stockholder meeting by means of remote communications; (iii) any stockholder seeking to
have the stockholders authorize or take corporate action by written consent shall, by written notice to the secretary of the Company, request that the board
fix a record date and the board shall adopt a resolution fixing the record date in all events within ten calendar days after a request is received; and (iv) a
written consent of stockholders shall not be effective unless a written consent signed by a sufficient number of stockholders to take such action is received
by us within 60 calendar days of the earliest dated written consent received.

Advance Notice Requirements for Stockholder Proposals and Director Nominations.

Our bylaws provide that stockholders seeking to bring business before an annual meeting of stockholders or to nominate candidates for election as directors
at  an  annual  meeting  of  stockholders  must  provide  timely  notice  in  writing.  To  be  timely,  a  stockholder’s  notice  must  be  delivered  to,  or  mailed  and
received by, the secretary of the Company at our principal executive offices not later than the close of business on the 90th calendar day, nor earlier than the
close of business on the 120th calendar day in advance of the date specified in the Company’s proxy statement released to stockholders in connection with
the previous year’s annual meeting of stockholders. If the date of the annual meeting is more than 30 calendar days before or after such anniversary date,
notice by the stockholder to be timely must be so not earlier than the close of business on the 120th calendar day in advance of such date of annual meeting
and not later than the close of business on the later of the 90th calendar day in advance of such date of annual meeting or the tenth calendar day following
the date on which public announcement of the date of the meeting is made. In no event shall the public announcement of an adjournment or postponement
of an annual meeting commence a new time period (or extend any time period) for the giving of an advance notice by any stockholder. Any stockholder
that proposes director nominations or other business must be a stockholder of record at the time the advance notice is delivered by such stockholder to us
and  entitled  to  vote  at  the  meeting.  Our  bylaws  also  specify  requirements  as  to  the  form  and  content  of  a  stockholder’s  notice.  These  provisions  may
preclude  stockholders  from  bringing  matters  before  an  annual  meeting  of  stockholders  or  from  making  nominations  for  the  election  of  directors  at  an
annual  meeting  of  stockholders.  Unless  otherwise  required  by  law,  any  director  nomination  or  other  business  shall  not  be  made  or  transacted  if  the
stockholder (or a qualified representative of the stockholder) does not appear at the meeting to present the director nominee or other proposed business.

Filling of Board Vacancies.

Our certificate of incorporation and bylaws provide that the authorized size of our board of directors shall be determined by the board by board resolution
from time to time and that our board of directors has the exclusive power to fill any vacancies and newly created directorships resulting from any increase
in the authorized number of directors and the stockholders do not have the power to fill such vacancies. Vacancies in our board of directors and newly
created directorships resulting from any increase in the authorized number of directors on our board of directors may be filled by a majority of the directors
remaining in office, even though that number may be less than a quorum of our board of directors, or by a sole remaining director. A director so elected to
fill a vacancy shall serve for the remaining term of the predecessor he or she replaced and until his or her successor is elected and has qualified, or until his
or her earlier resignation, removal or death.

Amendment of the Certificate of Incorporation.

Our certificate of incorporation may be amended, altered, changed or repealed at a meeting of our stockholders entitled to vote thereon by the affirmative
vote of a majority of the outstanding stock entitled to vote thereon and a majority of the outstanding stock of each class entitled to vote thereon as a class,
in the manner prescribed by the DGCL.

Amendment of the Bylaws.

Our bylaws may be amended or repealed, or new bylaws may be adopted, by either our board of directors or the affirmative vote of at least 66 2/3 percent
of the voting power of our outstanding shares of capital stock.

 
 
 
 
 
 
 
 
 
 
 
 
 
Section 203 of the Delaware General Corporation Law

We  are  subject  to  Section  203  of  the  DGCL,  which  prohibits  a  Delaware  corporation  from  engaging  in  any  business  combination  with  any  interested
stockholder for a period of three years after the date that such stockholder became an interested stockholder, with the following exceptions:

● before such  date,  the  board  of  directors  of  the  corporation  approved  either  the  business  combination  or  the  transaction  that  resulted  in  the

stockholder becoming an interested stockholder;

● upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at
least 85 percent of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes of determining the
voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (i) by persons who are
directors  and  also  officers  and  (ii)  pursuant  to  employee  stock  plans  in  which  employee  participants  do  not  have  the  right  to  determine
confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; and

● on or after such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of the
stockholders, and not by written consent, by the affirmative vote of at least 66 2/3 percent of the outstanding voting stock that is not owned by
the interested stockholder.

In general, Section 203 defines a business combination to include the following:

● any merger or consolidation involving the corporation and the interested stockholder;

● any  sale,  lease,  transfer,  pledge  or  other  disposition  of  ten  percent  or  more  of  the  assets  of  the  corporation  to  or  with  the  interested

stockholder;

● subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the

interested stockholder;

● any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the

corporation beneficially owned by the interested stockholder; and

● the receipt by the interested stockholder of the benefit of any loss, advances, guarantees, pledges or other financial benefits by or through the

corporation.

In general, Section 203 of the DGCL defines an “interested stockholder” as an entity or person who, together with the entity’s or person’s affiliates and
associates, beneficially owns, or is an affiliate of the corporation and within three years prior to the time of determination of interested stockholder status
did own, 15 percent or more of the outstanding voting stock of the corporation.

A  Delaware  corporation  may  “opt  out”  of  these  provisions  with  an  express  provision  in  its  certificate  of  incorporation. We  have  not  opted  out  of  these
provisions, which may as a result, discourage or prevent mergers or other takeover or change of control attempts of us.
