Corporation (&ldquo;Celsion&rdquo; and the &ldquo;Company&rdquo;) is a fully integrated development stage oncology drug company
focused on advancing a portfolio of innovative cancer treatments, including directed chemotherapies, DNA-mediated immunotherapy
and RNA based therapies. Our lead product candidate is ThermoDox<SUP>&reg;</SUP>, a proprietary heat-activated liposomal encapsulation
of doxorubicin, currently in a Phase III clinical trial for the treatment of primary liver cancer (the &ldquo;OPTIMA Study&rdquo;).
Second in our pipeline is GEN-1, a DNA-mediated immunotherapy for the localized treatment of ovarian cancer. These investigational
products are based on our two platform technologies which, in addition, provide the basis for the future development of a range
of therapeutics for difficult-to-treat forms of cancer. Our first platform is Lysolipid Thermally Sensitive Liposomes, a heat
sensitive liposomal based dosage form that targets disease with known therapeutics in the presence of mild heat. Our second is
TheraPlas, a novel nucleic acid-based treatment for local transfection of therapeutic plasmids. With 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.</FONT></P>

in conformity with GAAP requires management to make judgments, estimates, and assumptions that affect the amount reported in

Events and conditions arising subsequent to the most recent balance sheet date have been evaluated for their possible impact

potentially have an impact on the valuation of such assets in the future. The COVID-19 matter is discussed in more detail in

and submissions to the U.S. Food and Drug Administration. The Company has not generated significant revenue and have incurred
significant net losses in each year since our inception. As of March 31, 2020, the Company has incurred approximately $296 million
of cumulative net losses and we had approximately $17.5 million in cash, investment securities, interest receivable and receivables
from the sale of our State of New Jersey net operating losses. 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.</FONT></P>

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&rsquo;s ability to achieve profitability is dependent upon its

January 2020, the World Health Organization (WHO) declared an outbreak of coronavirus, COVID-19, to be a &ldquo;Public Health
Emergency of International Concern,&rdquo; 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 mid-May 2020,
has spread to over 100 countries, including the United States. Governments and businesses around the world have taken unprecedented
actions to mitigate the spread of COVID-19, including, but not limited to, shelter-in-place orders, quarantines, significant restrictions
on travel, as well as restrictions that prohibit many employees from going to work. Uncertainty with respect to the economic impacts
of the pandemic has introduced significant volatility in the financial markets. The Company did not observe significant impacts
on its business or results of operations for the three months ended March 31, 2020 due to the global emergence of COVID-19. While
the extent to which COVID-19 impacts the Company&rsquo;s future results will depend on future developments, the pandemic and associated
economic impacts could result in a material impact to the Company&rsquo;s future financial condition, results of operations and

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Investments in debt securities available for
sale with a fair value of $9,887,455 and $7,985,886 as of March 31, 2020 and December 31, 2019, 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&rsquo; equity in accumulated other comprehensive loss.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Investments
in debt securities available for sale are evaluated periodically to determine whether a decline in their value is other than temporary.
The term &ldquo;other than temporary&rdquo; 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.</FONT></P>

sale are determined by relying on the securities&rsquo; relationship to other benchmark quoted securities and classified its investments
as Level 2 items at March 31, 2020 and December 31, 2019. 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 thee-month period ended March 31, 2020 or during the year ended December

included in earnings and in-process R&amp;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

the closing of the acquisition, the IPR&amp;D was considered indefinite lived intangible assets and will not be amortized. IPR&amp;D
is reviewed for impairment at least annually as of our third quarter ended September 30, and whenever events or changes in circumstances

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 March 31, 2020,
we concluded that the Company&rsquo;s fair value exceeded its carrying value therefore &ldquo;it is not more likely than not&rdquo;

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">In
2011, the Company executed a lease (the &ldquo;Lease&rdquo;) 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 1<SUP>st</SUP> 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 1<SUP>st</SUP> 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 1<SUP>st</SUP> Lease Amendment and must provide the landlord notice by the 28<SUP>th</SUP> month of the
lease. Effective January 9, 2019, the Company amended the current terms of the 1<SUP>st</SUP> 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 2<SUP>nd</SUP> 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 2<SUP>nd</SUP> Lease Amendment.</FONT></P>

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.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">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 Condensed Consolidated Balance Sheet but had no impact on our condensed 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 2<SUP>nd</SUP> 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.</FONT></P>

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<SUP>&reg;</SUP> 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<SUP>&reg;</SUP>.
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<SUP>&reg;</SUP>. 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<SUP>&reg;</SUP>
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<SUP>&reg;

manufacture of three registration batches of ThermoDox<SUP>&reg;</SUP>.</FONT></P>

we filed a Current Report on Form 8-K announcing we entered into a loan agreement with Silicon Valley Bank (the &ldquo;PPP Loan&rdquo;),
pursuant to the Paycheck Protection Program of the Coronavirus Aid, Relief, and Economic Security Act. We thereafter received
proceeds of $632,220 under the PPP Loan. The PPP Loan application required Celsion to certify that there was economic uncertainty
surrounding the Company and that, as such, the PPP Loan was necessary to support our ongoing operations. Celsion made this certification
in good faith after analyzing, among other things, its financial situation and access to alternative forms of capital, and believes
that the Company satisfied all eligibility criteria for the PPP Loan, and that our receipt of the PPP Loan proceeds was consistent
with the broad objectives of the PPP of the CARES Act. The certification given with respect to the PPP Loan does not contain any
objective criteria and is subject to interpretation. In light of subsequent guidance issued by the U.S. Small Business Administration
in consultation with the U.S. Department of the Treasury, out of an abundance of caution we returned the proceeds of the PPP Loan
in full on May 13, 2020. Celsion may choose to reapply for the loan if the SBA provides future applicable guidance.</P>

for the OPTIMA Study, which is a pivotal, double-blind, placebo-controlled Phase III trial of ThermoDox&reg;, 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 called the HEAT Study (the &ldquo;HEAT Study&rdquo;). The OPTIMA Study is supported
by a hypothesis developed from an overall survival analysis of a large subgroup of patients from the HEAT Study.</FONT></P>

data analysis from our earlier Phase III HEAT Study suggest that ThermoDox&reg; 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 (&ldquo;PFS&rdquo;) 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. 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&reg; and optimized RFA provided
an average 54% risk improvement in OS compared to optimized RFA alone. The Hazard Ratio (&ldquo;HR&rdquo;) at this analysis is
0.65 (95% CI 0.45 - 0.94) with a p-value of 0.02. Median OS for the ThermoDox&reg; 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&reg; plus optimized
RFA group compared to less than 60 months projection for the optimized RFA only group).</FONT></P>

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&reg; that clearly
support the relationship between increased heating duration and doxorubicin concentrations.</FONT></P>

ThermoDox&reg; 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

the final efficacy analysis, if necessary, will be completed in the first quarter of 2021. If the study proves to provide a clinically
meaningful improvement in overall survival, Celsion will immediately apply for marketing authorization in the US, Europe and China.
ThermoDox&reg; 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&reg; 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 believes that applications
will be accepted in South Korea, Taiwan and Vietnam, three other significant markets for ThermoDox&reg; if it were to receive
approval in Europe, China or the U.S.</FONT></P>

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

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 &frac12; 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

article titled, &ldquo;<I>RFA Duration Per Tumor Volume May Correlate With Overall Survival in Solitary Hepatocellular Carcinoma
Patients Treated With RFA Plus Lyso-thermosensitive Liposomal Doxorubicin</I>,&rdquo; 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<SUP>&reg;</SUP>, 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<SUP>&reg;</SUP>,
compared to RFA alone. The authors conclude that increasing RFA heating time in combination with ThermoDox<SUP>&reg;</SUP> 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&rsquo;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

is a DNA-based immunotherapeutic product candidate for the localized treatment of ovarian cancer by intraperitoneally administering
an Interleukin-12 (&ldquo;IL-12&rdquo;) 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.</FONT></P>

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

oncology drug development company, today jointly announced with Medidata, a Dassault Syst&egrave;mes company, that examining matched
patient data provided by Medidata in a synthetic control arm (SCA) with results from the Company&rsquo;s completed Phase Ib dose-escalating
OVATION I Study with GEN-1 in Stage III/IV ovarian cancer patients showed positive results in progression-free survival (PFS).
The hazard ratio (HR) was 0.53 in the intent-to-treat (ITT) group, showing strong signals of efficacy. GEN-1, designed using Celsion&rsquo;s
proprietary TheraPlas platform technology, is an interleukin-12 (IL-12) DNA plasmid vector encased in a non-viral nanoparticle
delivery system, which enables cell transfection followed by persistent, local secretion of the IL-12 protein. Celsion believes
these data may warrant consideration of strategies to accelerate the clinical development program for GEN-1 in newly diagnosed,
advanced ovarian cancer patients by the U.S. Food and Drug Administration (FDA). In its March 2019 discussion with Celsion, the
FDA noted that preliminary findings from the Phase Ib OVATION I Study were exciting but lacked a control group to evaluate GEN-1&rsquo;s
independent impact on impressive tumor response, surgical results and PFS. The Agency encouraged the Company to continue its GEN-1
development program and consult with FDA with new findings that may have a bearing on designations such as Fast Track and Breakthrough
Therapy. <FONT STYLE="background-color: white">SCAs have the potential to revolutionize clinical trials in certain oncology indications
and some other diseases where a randomized control is not ethical or practical. SCAs are formed by carefully selecting control
patients from historical clinical trials to match the demographic and disease characteristics of the patients treated with the
new investigational product. SCAs have been shown to mimic the results of traditional randomized controls so that the treatment
effects of an investigational product can be visible by comparison to the SCA. SCAs can help advance the scientific validity of
single arm trials, and in certain indications, reduce time and cost, and expose fewer patients to placebos or existing standard-of-care
treatments that might not be effective for them.</FONT></FONT></P>

Technology Platform.</I></B> TheraPlas is a technology platform for the delivery of DNA and messenger RNA (&ldquo;mRNA&rdquo;)
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 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.</FONT></P>

results of the Company have fluctuated significantly in the past. In January 2020, the World Health Organization (WHO) declared

we filed a Current Report on Form 8-K announcing we entered into a loan agreement with Silicon Valley Bank (the &ldquo;PPP Loan&rdquo;),
pursuant to the Paycheck Protection Program of the Coronavirus Aid, Relief, and Economic Security Act. We thereafter received
proceeds of $632,220 under the PPP Loan.&nbsp; The PPP Loan application required Celsion to certify that there was economic uncertainty
surrounding the Company and that, as such, the PPP Loan was necessary to support our ongoing operations. Celsion made this certification
in good faith after analyzing, among other things, its financial situation and access to alternative forms of capital, and believes
that the Company satisfied all eligibility criteria for the PPP Loan, and that our receipt of the PPP Loan proceeds was consistent
with the broad objectives of the PPP of the CARES Act. The certification given with respect to the PPP Loan does not contain any
objective criteria and is subject to interpretation. In light of subsequent guidance issued by the U.S. Small Business Administration
in consultation with the U.S. Department of the Treasury, out of an abundance of caution we returned the proceeds of the PPP Loan
in full on May 13, 2020..&nbsp; Celsion may choose to reapply for the loan if the SBA provides future applicable guidance.</P>

on Form 8-K announcing we entered into a loan agreement with Silicon Valley Bank (the &ldquo;PPP Loan&rdquo;), pursuant to the
Paycheck Protection Program of the Coronavirus Aid, Relief, and Economic Security Act. We thereafter received proceeds of $632,220
under the PPP Loan.&nbsp; The PPP Loan application required Celsion to certify that there was economic uncertainty surrounding
the Company and that, as such, the PPP Loan was necessary to support our ongoing operations. Celsion made this certification in
good faith after analyzing, among other things, its financial situation and access to alternative forms of capital, and believes
that the Company satisfied all eligibility criteria for the PPP Loan, and that our receipt of the PPP Loan proceeds was consistent
with the broad objectives of the PPP of the CARES Act. The certification given with respect to the PPP Loan does not contain any
objective criteria and is subject to interpretation. In light of subsequent guidance issued by the U.S. Small Business Administration
in consultation with the U.S. Department of the Treasury, out of an abundance of caution we returned the proceeds of the PPP Loan
in full on May 13, 2020..&nbsp; Celsion may choose to reapply for the loan if the SBA provides future applicable guidance.</P>

management, including our chief executive officer and chief financial officer, does not expect that our disclosure controls and
procedures or our internal control over financial reporting will prevent all error and all fraud. A control system, no matter
how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system
are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance
that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include
the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple errors or mistakes.
Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management
override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood
of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential
future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with
the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements
due to error or fraud may occur and not be detected.</FONT></P>

following is a summary of the risk factors, uncertainties and assumptions that we believe are most relevant to our business. These
are factors that, individually or in the aggregate, we think could cause our actual results to differ significantly 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 of 1934, as amended and Section 27A of the Securities Act of 1933, as amended. Additional risks that we
currently believe are immaterial may also impair our business operations. Investors should carefully consider the risks described
below before making an investment decision and understand that it is not possible to predict or identify all such factors. Consequently,
investors 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. The description provided in this Item 1A includes any material changes to and supersedes the description of the
risk factors associated with our business previously disclosed in Item 1A of our Annual Report on Form 10-K for the fiscal year
ended December 31, 2019 filed on March 25, 2020 with the SEC. In assessing these risks, investors should also refer to the other
information contained or incorporated by reference in this Quarterly Report and our other filings made from time to time with
the SEC.</FONT></P>

Our ability to achieve profitability, if ever, will depend on, among other things, us or our collaborators successfully developing

products on commercially reasonable terms, delays or setbacks we may experience associated with our preclinical studies, clinical
trials, third parties, or supply chain due to the COVID-19 pandemic, 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

have devoted our resources to developing a new generation of products and will not be able to market these products until we have

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&reg;
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.</FONT></P>

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&reg; 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.</FONT></P>

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.</P>

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.</FONT></P>

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

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

in response to the COVID-19 global pandemic, on March 10, 2020, the FDA announced its intention to postpone most inspections of
foreign manufacturing facilities and products through at least April 2020, though no set end date has been determined. On March
18, 2020, the FDA announced its intention to temporarily postpone routine surveillance inspections of domestic manufacturing facilities.
Regulatory authorities outside the United States may adopt similar restrictions or other policy measures in response to the COVID-19
pandemic and provide guidance regarding the conduct of clinical trials , which guidance continues to evolve. In April 2020, the
FDA stated that its New Drug Program was continuing to meet program user fee performance goals, but due to many agency staff working
on COVID-19 activities, it was possible that the FDA would not be able to sustain that level of performance indefinitely. If global
health concerns continue to prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews
or other regulatory activities, it could significantly impact the ability of the FDA to timely review and process our regulatory
submissions, which could have a material adverse effect on our business</FONT></P>

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.</FONT></P>

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, if we were to engage an NIH-funded institution to conduct
a clinical trial, we may be subject to review by the NIH Office of Biotechnology Activities&rsquo; Recombinant DNA Advisory Committee
(the RAC). If undertaken, RAC can delay the initiation of a clinical trial, even if the FDA has reviewed the trial design and
details and approved its initiation. Conversely, the FDA can put an investigational new drug (IND) application on a clinical hold
even if the RAC has provided a favorable review or an exemption from in-depth, public 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.</FONT></P>

if our product candidates initially show promise in these early clinical trials, the side effects of drugs are frequently only

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.</FONT></P>

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.</FONT></P>

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.</FONT></P>

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.</FONT></P>

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&rsquo;s patent and/or that
the third party&rsquo;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.</FONT></P>

though we have obtained Orphan Drug Designation for ThermoDox&reg; and may obtain such designation for other product candidates

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.</FONT></P>

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&rsquo;s outpatient drugs to be covered under Medicare Part D.</FONT></P>

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 <I>Moda Health Plan, Inc.
v. United States</I>, which will determine whether the government must make risk corridor payments. The U.S. Supreme Court&rsquo;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&rsquo;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 &ldquo;individual mandate&rdquo;
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.</FONT></P>

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&rsquo;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 2030, 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 &ldquo;donut hole&rdquo;. However, pursuant to the CARES Act, these
reductions will be suspended from May 1, 2020 through December 31, 2020 due to the COVID-19 pandemic. 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

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.</FONT></P>

the federal level, the Trump administration&rsquo;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 &ldquo;Blueprint&rdquo; 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&rsquo;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. For example, the Lower Drug Costs Now Act of 2019 was introduced in the House of Representatives on September 19, 2019
and would require HHS to directly negotiate drug prices with manufacturers. The Lower Drugs Costs Now Act of 2019 has passed out
of the House and was delivered to the Senate on December 16, 2019. However, it is unclear whether this bill will make it through
both chambers and be signed into law, and if enacted, what effect it would have on our business. 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 have increasingly passed legislation and implemented regulations designed to control pharmaceutical
and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product
access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other

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&rsquo; 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,

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

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.</FONT></P>

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.</FONT></P>

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 &ldquo;key

rules dealing with U.S. federal, state, and local income taxation are constantly under review by persons involved in the legislative
process and by the Internal Revenue Service and the U.S. Treasury Department. Changes to tax laws (which changes may have retroactive
application) could adversely affect us or holders of our common stock. In recent years, many such changes have been made and changes
are likely to continue to occur in the future. For example, on March 27, 2020, President Trump signed into law the &ldquo;Coronavirus
Aid, Relief, and Economic Security Act&rdquo; or the CARES Act, which included certain changes in tax law intended to stimulate
the U.S. economy in light of the COVID-19 coronavirus outbreak, including temporary beneficial changes to the treatment of net
operating losses, interest deductibility limitations and payroll tax matters. Future changes in tax laws could have a material
adverse effect on our business, cash flow, financial condition or results of operations. We urge investors to consult with their
legal and tax advisers regarding the implications of potential changes in tax laws on an investment in our common stock.</FONT></P>

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. Net operating losses generated after December 31, 2017 are not
subject to expiration, and generally <STRIKE>but</STRIKE> may not be carried back to prior taxable years except that, under the
CARES Act, net operating losses generated in 2018, 2019 and 2020 may be carried back five taxable years. Additionally, for taxable
years beginning after December 31, 2020, the deductibility of such federal net operating losses is limited to 80% of our taxable
income in any future taxable year. 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 &ldquo;ownership change&rdquo; is subject to limitations on its ability to utilize its pre-change NOLs to offset
future taxable income. During 2018, 2017 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.</FONT></P>

The fair values of securities available for sale are determined by relying on the securities&amp;#8217;&#13;relationship to other benchmark quoted securities and classified its investments as Level 2 items at March 31, 2020 and December&#13;31, 2019. There were no transfers of assets or liabilities between Level 1 and Level 2 and no transfers in or out of Level 3 during&#13;the thee-month period ended March 31, 2020 or during the year ended December 31, 2019. The changes in Level 3 liabilities were&#13;the result of changes in the fair value of the earn-out milestone liability included in earnings and in-process R&amp;#38;D. The earnout&#13;milestone liability is valued using a risk-adjusted assessment of the probability of payment of each milestone, discounted to present&#13;value using an estimated time to achieve the milestone (see Note 13). The in-process R&amp;#38;D is valued using a multi-period excess&#13;earnings method (see Note 8).&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

The Shares were offered by the Company pursuant to a registration&#13;statement on Form S-3 (File No. 333-227236). The Purchase Agreement contains customary representations, warranties and agreements&#13;by the Company and customary conditions to closing. In a concurrent private placement (the &amp;#8220;Private Placement&amp;#8221;), the&#13;Company agreed to issue to the investors that participated in the Offering, for no additional consideration, warrants, to purchase&#13;up to 2,971,428 shares of Common Stock (the &amp;#8220;Original Warrants&amp;#8221;).

The&#13;Warrants had an exercise price of $1.15 per share subject to adjustment as provided therein. On March 12, 2020 the Company entered&#13;into private exchange agreements (the &amp;#8220;Exchange Agreements&amp;#8221;) with holders the Warrants. Pursuant to the Exchange Agreements,&#13;in return for a higher exercise price of $1.24 per share of Common Stock, the Company issued new warrants to the Investors to&#13;purchase up to 3,200,000 shares of Common Stock (the &amp;#8220;Exchange Warrants&amp;#8221;) in exchange for the Original Warrants. The&#13;Exchange Warrants, like the Original Warrants, are initially exercisable six months following their issuance (the &amp;#8220;Initial&#13;Exercise Date&amp;#8221;) and expire on the five-year anniversary of their Initial Exercise Date. Other than having a higher exercise&#13;price, different issue date, Initial Exercise Date and expiration date, the terms of the Exchange Warrants are identical to those&#13;of the Original Warrants.&lt;/p&gt;</us-gaap:StockholdersEquityNoteDisclosureTextBlock>

Ltd. (Hisun) for the production of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt;&#13;in the China territory. In accordance with the terms of the agreement, Hisun will be responsible for providing all of the technical&#13;and regulatory support services, including the costs of all technical transfer, registration and bioequivalence studies, technical&#13;transfer costs, Celsion consultative support costs and the purchase of any necessary equipment and additional facility costs necessary&#13;to support capacity requirements for the manufacture of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt;. Celsion will repay Hisun for the aggregate&#13;amount of these development costs and fees commencing on the successful completion of three registration batches of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt;.&#13;Hisun is also obligated to certain performance requirements under the agreement. The agreement will initially be limited to a percentage&#13;of the production requirements of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt; in the China territory with Hisun retaining an option for additional&#13;global supply after local regulatory approval in the China territory. In addition, Hisun will collaborate with Celsion around the&#13;regulatory approval activities for ThermoDox&lt;sup&gt;&amp;#174; &lt;/sup&gt;with the China State Food and Drug Administration (CHINA FDA). During&#13;the first quarter of 2015, Hisun completed the successful manufacture of three registration batches of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt;.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On January 18, 2013, we entered into a technology&#13;development contract with Hisun, pursuant to which Hisun paid us a non-refundable research and development fee of $5 million to&#13;support our development of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt; in mainland China, Hong Kong and Macau (the China territory). Following our&#13;announcement on January 31, 2013 that the HEAT study failed to meet its primary endpoint, Celsion and Hisun have agreed that the&#13;Technology Development Contract entered into on January 18, 2013 will remain in effect while the parties continue to collaborate&#13;and are evaluating the next steps in relation to ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt; , which include the sub-group analysis of patients&#13;in the Phase III HEAT Study for the hepatocellular carcinoma clinical indication and other activities to further the development&#13;of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt; for the Greater China market. The $5.0 million received as a non-refundable payment from Hisun in&#13;the first quarter 2013 has been recorded to deferred revenue and will continue to be amortized over the 10 -year term of the agreement,&#13;until such time as the parties find a mutually acceptable path forward on the development of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt; based on&#13;findings of the ongoing post-study analysis of the HEAT Study data.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 7.7pt; text-align: justify"&gt;&amp;#160;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On July 19, 2013, the Company and Hisun entered&#13;into a Memorandum of Understanding to pursue ongoing cooperation for the continued clinical development of ThermoDox &lt;sup&gt;&amp;#174;&lt;/sup&gt;&#13;as well as the technology transfer relating to the commercial manufacture of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt; for the China territory.&#13;This expanded level of cooperation includes development of the next generation liposomal formulation with the goal of creating&#13;safer, more efficacious versions of marketed cancer chemotherapeutics.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Among the key provisions of the Celsion-Hisun&#13;Memorandum of Understanding are:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="font: 12pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"&gt;&#13;&lt;tr style="vertical-align: top"&gt;&#13;    &lt;td style="width: 48px; text-align: justify"&gt;&lt;font style="font-size: 10pt"&gt;&lt;b&gt;&amp;#9679;&lt;/b&gt;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="text-align: justify"&gt;&lt;font style="font-size: 10pt"&gt;Hisun will provide the Company with internal resources necessary to complete the technology transfer of the Company&amp;#8217;s proprietary manufacturing process and the production of registration batches for the China territory;&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: top"&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="text-align: justify"&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: top"&gt;&#13;    &lt;td style="text-align: justify"&gt;&lt;font style="font-size: 10pt"&gt;&lt;b&gt;&amp;#9679;&lt;/b&gt;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="text-align: justify"&gt;&lt;font style="font-size: 10pt"&gt;Hisun will coordinate with the Company around the clinical and regulatory approval activities for ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt; as well as other liposomal formations with the CHINA FDA; and&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: top"&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="text-align: justify"&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: top"&gt;&#13;    &lt;td style="text-align: justify"&gt;&lt;font style="font-size: 10pt"&gt;&lt;b&gt;&amp;#9679;&lt;/b&gt;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="text-align: justify"&gt;&lt;font style="font-size: 10pt"&gt;Hisun will be granted a right of &lt;i&gt;first&lt;/i&gt; offer for a commercial license to ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt; for the sale and distribution of ThermoDox&lt;sup&gt;&amp;#174; &lt;/sup&gt;in the China territory.&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;/table&gt;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On August 8, 2016, we signed a Technology Transfer,&#13;Manufacturing and Commercial Supply Agreement (&amp;#8220;GEN-1 Agreement&amp;#8221;) with Hisun to pursue an expanded partnership for&#13;the technology transfer relating to the clinical and commercial manufacture and supply of GEN- 1, Celsion&amp;#8217;s proprietary gene&#13;mediated, IL- 12 immunotherapy, for the greater China territory, with the option to expand into other countries in the rest of&#13;the world after all necessary regulatory approvals are in effect.

The&#13;Company concluded that the license was not distinct since its value is closely tied to the ongoing research and development activities.&#13;As such, the license and the research and development services are bundled as a single performance obligation.

(Brandywine), a Delaware limited partnership for a 10,870 square&#13;foot premises located in Lawrenceville, New Jersey and relocated its offices to Lawrenceville, New Jersey from Columbia, Maryland.&#13;The Lease had an initial term of 66 months. In late 2015, Lenox Drive Office Park LLC, purchased the real estate and office building&#13;and assumed the Lease. This Lease was set to expire on April 30, 2017. In April 2017, the Company and the landlord amended the&#13;Lease effective May 1, 2017. The 1&lt;sup&gt;st&lt;/sup&gt; Lease Amendment extended the term of the agreement for an additional 64 months,&#13;reduced the premises to 7,565 square feet, reduced the monthly rent and provided four months free rent. The monthly rent ranged&#13;from approximately $18,900 in the first year to approximately $20,500 in the final year of the 1&lt;sup&gt;st&lt;/sup&gt; Lease Amendment.&#13;The Company also had a one-time option to cancel the lease as of the 40th month after the commencement date of the 1&lt;sup&gt;st&lt;/sup&gt;&#13;Lease Amendment and must provide the landlord notice by the 28&lt;sup&gt;th&lt;/sup&gt; month of the lease. Effective January 9, 2019, the&#13;Company amended the current terms of the 1&lt;sup&gt;st&lt;/sup&gt; Lease Amendment to increase the size of the premises by 2,285 square feet&#13;to 9,850 square feet and also extended the lease term by one year to September 1, 2023. In conjunction with this 2&lt;sup&gt;nd&lt;/sup&gt;&#13;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&#13;to the landlord by the end of August 2020. The monthly rent will range from approximately $25,035 in the first year to approximately&#13;$27,088 in the final year of the 2&lt;sup&gt;nd&lt;/sup&gt; Lease Amendment.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In connection with the EGEN Asset Purchase&#13;Agreement in June 2014, the Company assumed the existing lease with another landlord for an 11,500 square foot premises located&#13;in Huntsville Alabama. In January 2018, the Company and the Huntsville landlord entered into a new 60-month lease which reduced&#13;the premises to 9,049 square feet with rent payments of approximately $18,100 per month.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;We adopted ASC Topic 842 on January 1, 2019&#13;using the modified retrospective transition method for all lease arrangements at the beginning of the period of adoption. Results&#13;for reporting periods beginning January 1, 2019 are presented under ASC 842, while prior period amounts were not adjusted and continue&#13;to be reported in accordance with our historic accounting under Topic 840, Leases. The standard had a material impact on our Condensed&#13;Consolidated Balance Sheet but had no impact on our condensed consolidated net earnings and cash flows. The most significant impact&#13;of adopting ASC Topic 842 was the recognition of the right-of-use (ROU) asset and lease liabilities for operating leases, which&#13;are presented in the following three-line items on the Consolidated Condensed Balance Sheet: (i) operating lease right-of-use asset;&#13;(ii) current operating lease liabilities; and (iii) operating lease liabilities. Therefore, on date of adoption of ASC Topic 842,&#13;the Company recognized a ROU asset of $1.4 million, operating lease liabilities, current and non-current collectively, of $1.5&#13;million and reduced other liabilities by approximately $0.1 million. We elected the package of practical expedients for leases&#13;that commenced before the effective date of ASC Topic 842 whereby we elected to not reassess the following: (i) whether any expired&#13;or existing contracts contain leases; (ii) the lease classification for any expired or existing leases; and (iii) initial direct&#13;costs for any existing leases. In addition, we have lease agreements with lease and non-lease components, and we have elected the&#13;practical expedient for all underlying asset classes and account for them as a single lease component. We have no finance leases.&#13;We determine if an arrangement is a lease at inception. We have operating leases for office space and research and development&#13;facilities. Neither of our leases include options to renew, however, one contains an option for early termination. We considered&#13;the option of early termination in measurement of right-of-use assets and lease liabilities and we determined it is not reasonably&#13;certain to be terminated. In connection with the 2&lt;sup&gt;nd&lt;/sup&gt; Lease Amendment for the New Jersey office lease in January 2019,&#13;the Company considered this as one modified lease and not as two separate leases. Therefore, in January 2019, the Company determined&#13;this lease was an operating lease and remeasured the ROU asset and lease liability. Therefore, the Company increased the ROU asset&#13;and operating lease liabilities by $0.4 million to $1.8 million and $1.9 million, respectively.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

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.</us-gaap:LesseeOperatingLeaseOptionToExtend>

The Company has not generated significant revenue and have incurred significant net losses in each year since our&#13;inception.

This virus continues to spread globally and, as of mid-May 2020, has spread to over 100 countries, including the United&#13;States. Governments and businesses around the world have taken unprecedented actions to mitigate the spread of COVID-19, including,&#13;but not limited to, shelter-in-place orders, quarantines, significant restrictions on travel, as well as restrictions that prohibit&#13;many employees from going to work. Uncertainty with respect to the economic impacts of the pandemic has introduced significant&#13;volatility in the financial markets. The Company did not observe significant impacts on its business or results of operations for&#13;the three months ended March 31, 2020 due to the global emergence of COVID-19. While the extent to which COVID-19 impacts the Company&amp;#8217;s&#13;future results will depend on future developments, the pandemic and associated economic impacts could result in a material impact&#13;to the Company&amp;#8217;s future financial condition, results of operations and cash flows.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&amp;#8217;s ability to raise additional&#13;capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility&#13;in, financial markets in the United States and worldwide resulting from the ongoing COVID-19 pandemic.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The disruptions caused by COVID-19 may also&#13;disrupt the clinical trials process and enrollment of patients.

The Company may need to obtain additional funds sooner or in greater amounts than it currently anticipates.&#13;Potential sources of financing include strategic relationships, public or private sales of the Company&amp;#8217;s shares or debt,&#13;the sale of the Company&amp;#8217;s State of New Jersey net operating losses and other sources. If the Company raises funds by selling&#13;additional shares of common stock or other securities convertible into common stock, the ownership interest of existing stockholders&#13;may be diluted.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;During 2019 and 2018, the Company submitted&#13;applications to sell a portion of the Company&amp;#8217;s State of New Jersey net operating losses as part of the Technology Business&#13;Tax Certificate Program sponsored by The New Jersey Economic Development Authority. Under the program, emerging biotechnology companies&#13;with unused NOLs and unused research and development credits are allowed to sell these benefits to other companies. As more fully&#13;discussed in Note 9, the Company received approval from the New Jersey Economic Development Authority to sell $1.9 million of its&#13;State of New Jersey net operating losses recognizing a tax benefit for the year ended December 31, 2019 for the net proceeds (approximately&#13;$1.8 million). In early 2020, the Company entered into an agreement to sell these net operating losses, In April of 2020, the Company&#13;completed the sale of the New Jersey net operating losses and received the $1.8 million net proceeds. In 2018, the Company completed&#13;the sale of a portion of its New Jersey net operating losses for 2011 - 2017 totaling approximately $11.1 for net proceeds of approximately&#13;$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.&#13;The Company has approximately $2.0 million available in future tax benefits remaining under the NOL Program for future years.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In June 2018, the Company entered into the&#13;Horizon Credit Agreement with Horizon that provided $10 million in new capital. The obligations under the Horizon Credit Agreement&#13;are secured by a first-priority security interest in substantially all assets of Celsion other than intellectual property assets.&#13;Payments under the loan agreement are interest only (calculated based on one-month LIBOR plus 7.625%) for the first twenty-four&#13;(24) months after through July 2020, closing, followed by a 24-month amortization period of principal and interest starting on&#13;August 1, 2020 and ending through the scheduled maturity date.

In addition, CLSN Laboratories assumed certain specified liabilities of EGEN, including the liabilities arising&#13;out of the acquired contracts and other assets relating to periods after the closing date.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Acquired In-process Research and Development&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Acquired in-process research and development&#13;(IPR&amp;#38;D) consists of EGEN&amp;#8217;s drug technology platforms: TheraPlas and TheraSilence. The fair value of the IPR&amp;#38;D drug&#13;technology platforms was estimated to be $24.2 million as of the acquisition date. As of the closing of the acquisition, the IPR&amp;#38;D&#13;was considered indefinite lived intangible assets and will not be amortized. IPR&amp;#38;D is reviewed for impairment at least annually&#13;as of our third quarter ended September 30, and whenever events or changes in circumstances indicate that the carrying value of&#13;the assets might not be recoverable. The Company&amp;#8217;s IPR&amp;#38;D consisted of three core elements, its RNA delivery system, its&#13;glioblastoma multiforme cancer (GBM) product candidate and its ovarian cancer indication.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&amp;#8217;s ovarian cancer indication,&#13;with original value of $13.3 million has not been impaired since its acquisition. At September 30, 2019 the Company evaluated its&#13;IPR&amp;#38;D of the ovarian cancer indication and concluded that it is not more likely than not that the asset is impaired. As no&#13;other indicators of impairment existed during the fourth quarter of 2019 or first quarter of 2020, no impairment charges were recorded&#13;during the three months ended March 31, 2020 and 2019.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&amp;#8217;s GBM candidate, with original&#13;value of $9.4 million had cumulative impairments through 2018 of $7 million, with remaining carrying value of $2.4 million at December&#13;31, 2019 and March 31, 2020, On September 30, 2019, the Company evaluated its IPR&amp;#38;D of the (GBM) product candidate and concluded&#13;that it is not more likely than not that the asset is further impaired. As no other indicators of impairment existed during the&#13;fourth quarter of 2019 and in the first quarter of 2020, no impairment charges were recorded during the three months ended March&#13;31, 2020 and 2019.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&amp;#8217;s RNA delivery system, with&#13;an initial value of $1.5 million was previously fully impaired.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Covenants Not to Compete&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Pursuant to the EGEN Purchase Agreement, EGEN&#13;provided certain covenants (&amp;#8220;Covenant Not To Compete&amp;#8221;) to the Company whereby EGEN agreed, during the period ending&#13;on the seventh anniversary of the closing date of the acquisition on June 20, 2014, not to enter into any business, directly or&#13;indirectly, which competes with the business of the Company nor will it contact, solicit or approach any of the employees of the&#13;Company for purposes of offering employment.

These investments are valued at estimated fair value, with unrealized gains and losses reported as a separate&#13;component of stockholders&amp;#8217; equity in accumulated other comprehensive loss.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Investments in debt securities available for&#13;sale are evaluated periodically to determine whether a decline in their value is other than temporary. The term &amp;#8220;other than&#13;temporary&amp;#8221; is not intended to indicate a permanent decline in value. Rather, it means that the prospects for near term recovery&#13;of value are not necessarily favorable, or that there is a lack of evidence to support fair values equal to, or greater than, the&#13;carrying value of the security. Management reviews criteria such as the magnitude and duration of the decline, as well as the reasons&#13;for the decline, to predict whether the loss in value is other than temporary. Once a decline in value is determined to be other&#13;than temporary, the value of the security is reduced and a corresponding charge to earnings is recognized.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

We thereafter received proceeds&#13;of $632,220 under the PPP Loan. The PPP Loan application required Celsion to certify that there was economic uncertainty surrounding&#13;the Company and that, as such, the PPP Loan was necessary to support our ongoing operations. Celsion made this certification in&#13;good faith after analyzing, among other things, its financial situation and access to alternative forms of capital, and believes&#13;that the Company satisfied all eligibility criteria for the PPP Loan, and that our receipt of the PPP Loan proceeds was consistent&#13;with the broad objectives of the PPP of the CARES Act. The certification given with respect to the PPP Loan does not contain any&#13;objective criteria and is subject to interpretation. In light of subsequent guidance issued by the U.S. Small Business Administration&#13;in consultation with the U.S. Department of the Treasury, out of an abundance of caution we returned the&#13;proceeds of the PPP Loan in full on May 13, 2020. Celsion may choose to reapply for the loan if the SBA provides future applicable&#13;guidance.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="background-color: white"&gt;As disclosed&#13;in Note 10, the Company and Horizon &lt;/font&gt;agreed to defer the first two principal payments totaling a $833,333 due in August&#13;and September 2020.&lt;/p&gt;</us-gaap:SubsequentEventsTextBlock>

All significant intercompany balances and transactions&#13;have been eliminated in consolidation. Certain information and disclosures normally included in financial statements prepared in&#13;accordance with GAAP have been condensed or omitted pursuant to such rules and regulations.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In the opinion of management, all adjustments,&#13;consisting only of normal recurring accruals considered necessary for a fair presentation, have been included in the accompanying&#13;unaudited condensed consolidated financial statements. Operating results for the three-month period March 31, 2020 and 2019 are&#13;not necessarily indicative of the results that may be expected for any other interim period(s) or for any full year.

Actual results could differ materially from those estimates. Events&#13;and conditions arising subsequent to the most recent balance sheet date have been evaluated for their possible impact on the financial&#13;statements and accompanying notes. With the recent introduction of the COVID-19 pandemic to the United States, the Company continues&#13;to monitor the impact of this pandemic on its financial condition and results of operations, along with the valuation of its long-term&#13;assets, intangible assets, and goodwill. &amp;#160;The effect of this matter could potentially have an impact on the valuation of&#13;such assets in the future.

Our lead&#13;product candidate is ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt;, a proprietary heat-activated liposomal encapsulation of doxorubicin, currently&#13;in a Phase III clinical trial for the treatment of primary liver cancer (the &amp;#8220;OPTIMA Study&amp;#8221;). Second in our pipeline&#13;is GEN-1, a DNA-mediated immunotherapy for the localized treatment of ovarian cancer. These investigational products are based&#13;on our two platform technologies which, in addition, provide the basis for the future development of a range of therapeutics for&#13;difficult-to-treat forms of cancer. Our first platform is Lysolipid Thermally Sensitive Liposomes, a heat sensitive liposomal&#13;based dosage form that targets disease with known therapeutics in the presence of mild heat. Our second is TheraPlas, a novel&#13;nucleic acid-based treatment for local transfection of therapeutic plasmids. With these technologies we are working to develop&#13;and commercialize more efficient, effective and targeted oncology therapies that maximize efficacy while minimizing side-effects&#13;common to cancer treatments.&lt;/p&gt;</us-gaap:BusinessDescriptionAndAccountingPoliciesTextBlock>

Unless&#13;otherwise discussed, we believe that the impact of recently issued accounting pronouncements will not have a material impact on&#13;the Company&amp;#8217;s condensed consolidated financial position, results of operations, and cash flows, or do not apply to our operations.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In June 2016, the FASB issued Accounting Standard&#13;Update No. 2016-13, &amp;#8220;Financial Instruments &amp;#8211; Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments&amp;#8221;,&#13;which modifies the measurement of expected credit losses on certain financial instruments. The Company will adopt ASU 2016-13 in&#13;its first quarter of 2021 utilizing the modified retrospective transition method. Based on the composition of the Company&amp;#8217;s&#13;investment portfolio and current market conditions, the adoption of ASU 2016-13 is not expected to have a material impact on its&#13;condensed consolidated financial statements.&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In August 2018, the FASB issued ASU No. 2018-13,&#13;&lt;i&gt;Fair Value Measurement: Disclosure Framework &amp;#8211; Changes to the Disclosure Requirements for Fair Value Measurement&lt;/i&gt;,&#13;which adds and modifies certain disclosure requirements for fair value measurements. Under the new guidance, entities will no longer&#13;be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, or valuation&#13;processes for Level 3 fair value measurements. However, public companies will be required to disclose the range and weighted average&#13;of significant unobservable inputs used to develop Level 3 fair value measurements, and related changes in unrealized gains and&#13;losses included in other comprehensive income. This update is effective for annual periods beginning after December 15, 2019, and&#13;interim periods within those periods, and early adoption is permitted. The adoption of this standard did not have an impact on&#13;the Company&amp;#8217;s condensed consolidated financial statements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In December 2019, the FASB issued ASU No.&#13;2019-12, Income Taxes (Topic 740). The standard simplifies the accounting for incomes taxes by removing certain exceptions to&#13;the general principles in Topic 740 related to the approach for intra-period tax allocation and the recognition of deferred tax&#13;liabilities for outside basis differences. The standard also clarifies the accounting for transactions that result in a step-up&#13;in the tax basis of goodwill. The standard also improves consistent application of and simplifies GAAP for other areas of Topic&#13;740 by clarifying and amending existing guidance. The amendment is effective for fiscal years, and interim periods within those&#13;fiscal years, beginning after December 15, 2020. Early adoption is permitted. The Company is currently evaluating the impact that&#13;the adoption of this standard will have on its condensed consolidated financial statements.&lt;/p&gt;</us-gaap:DescriptionOfNewAccountingPronouncementsNotYetAdopted>

The dilutive effects of preferred stock, options and warrants&#13;and their equivalents are computed using the treasury stock method.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The total number of shares of common stock&#13;issuable upon exercise of warrants, stock option grants and equity awards were 7,982,990 and 5,412,554 shares for the three-month&#13;periods ended March 31, 2020 and 2019, respectively. Warrants with an exercise price of $0.01 (as more fully described in Note&#13;13) exercisable for 200,000 shares of common stock were considered issued in calculating basic loss per share. For the three-month&#13;periods ended March 31, 2020 and 2019, diluted loss per common share was the same as basic loss per common share as the other warrants&#13;and equity awards that were convertible into shares of the Company&amp;#8217;s common stock were excluded from the calculation of diluted&#13;loss per common share as their effect would have been anti-dilutive.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company did not pay any dividends during&#13;the three-month periods ended March 31, 2020 and 2019.&lt;/p&gt;</us-gaap:EarningsPerShareTextBlock>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">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<sup>&#174;</sup>
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<sup>&#174;</sup>. 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<sup>&#174;</sup>.
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<sup>&#174;</sup> 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<sup>&#174; </sup>with the China State Food and Drug Administration (CHINA FDA). During
the first quarter of 2015, Hisun completed the successful manufacture of three registration batches of ThermoDox<sup>&#174;</sup>.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">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<sup>&#174;</sup> 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<sup>&#174;</sup> , 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<sup>&#174;</sup> 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<sup>&#174;</sup> based on
findings of the ongoing post-study analysis of the HEAT Study data.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">On July 19, 2013, the Company and Hisun entered
into a Memorandum of Understanding to pursue ongoing cooperation for the continued clinical development of ThermoDox <sup>&#174;</sup>
as well as the technology transfer relating to the commercial manufacture of ThermoDox<sup>&#174;</sup> for the China territory.
This expanded level of cooperation includes development of the next generation liposomal formulation with the goal of creating
safer, more efficacious versions of marketed cancer chemotherapeutics.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company evaluated the Hisun arrangement
in accordance with ASC 606 and determined that its performance obligations under the agreement include the non-exclusive, royalty-free
license, research and development services to be provided by the Company, and its obligation to serve on a joint committee. The
Company concluded that the license was not distinct since its value is closely tied to the ongoing research and development activities.
As such, the license and the research and development services are bundled as a single performance obligation. Since the provision
of the license and research and development services are considered a single performance obligation, the $5,000,000 upfront payment
is being recognized as revenue ratably through 2022.&#160;</p><span></span>

Update No. 2016-13, &#8220;Financial Instruments &#8211; Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments&#8221;,
which modifies the measurement of expected credit losses on certain financial instruments. The Company will adopt ASU 2016-13 in
its first quarter of 2021 utilizing the modified retrospective transition method. Based on the composition of the Company&#8217;s
investment portfolio and current market conditions, the adoption of ASU 2016-13 is not expected to have a material impact on its
condensed consolidated financial statements.&#160;</p>

<i>Fair Value Measurement: Disclosure Framework &#8211; Changes to the Disclosure Requirements for Fair Value Measurement</i>,
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 adoption of this standard did not have an impact on
the Company&#8217;s condensed consolidated financial statements.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">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 intra-period 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 condensed consolidated financial statements.</p><span></span>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">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 (&#8220;EGEN&#8221;). We acquired all of EGEN&#8217;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.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Acquired in-process research and development
(IPR&#38;D) consists of EGEN&#8217;s drug technology platforms: TheraPlas and TheraSilence. The fair value of the IPR&#38;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&#38;D
was considered indefinite lived intangible assets and will not be amortized. IPR&#38;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. The Company&#8217;s IPR&#38;D consisted of three core elements, its RNA delivery system, its
glioblastoma multiforme cancer (GBM) product candidate and its ovarian cancer indication.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s ovarian cancer indication,
with original value of $13.3 million has not been impaired since its acquisition. At September 30, 2019 the Company evaluated its
IPR&#38;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 or first quarter of 2020, no impairment charges were recorded
during the three months ended March 31, 2020 and 2019.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s GBM candidate, with original
value of $9.4 million had cumulative impairments through 2018 of $7 million, with remaining carrying value of $2.4 million at December
31, 2019 and March 31, 2020, On September 30, 2019, the Company evaluated its IPR&#38;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 and in the first quarter of 2020, no impairment charges were recorded during the three months ended March
31, 2020 and 2019.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Pursuant to the EGEN Purchase Agreement, EGEN
provided certain covenants (&#8220;Covenant Not To Compete&#8221;) 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 $56,829 in each of the three-month periods ended March 31, 2020 and 2019. The carrying value
of the Covenant Not to Compete was $284,147, net of $1,307,067 accumulated amortization as of March 31, 2020 and $340,976, net
of $1,250,238 accumulated amortization, as of December 31, 2019.</p>

September 30 or sooner if we believe indicators of impairment exist. As of March 31, 2020, we concluded that the Company&#8217;s

the Company held on May 15, 2018, stockholders approved the Celsion Corporation 2018 Stock Incentive Plan (the &#8220;2018 Plan&#8221;).
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

The 2018 Plan replaced the 2007 Plan although the 2007 Plan remains in effect for awards previously granted under the 2007 Plan.
Under the terms of the 2018 Plan, any shares subject to an award under the 2007 Plan which are not delivered because of the expiration,

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.</p>

totaling 13,000 shares of Celsion common stock to two new employees collectively. Each award has a grant date of the date of grant.

<td class="text">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.<span></span>

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">On February 27, 2020, we entered into a Securities
Purchase Agreement (the &#8220;Purchase Agreement&#8221;) with several institutional investors, pursuant to which we agreed to
issue and sell, in a registered direct offering (the &#8220;February 2020 Offering&#8221;), an aggregate of 4,571,428 shares (the
&#8220;Shares&#8221;) 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 &#8220;Private Placement&#8221;), 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 &#8220;Original Warrants&#8221;). The Original Warrants were initially exercisable
six months following their date of issue 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 &#8220;Exchange Agreements&#8221;) 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 &#8220;Exchange Warrants&#8221;) in exchange for the Original Warrants. The
Exchange Warrants, like the Original Warrants, are initially exercisable six months following their issuance (the &#8220;Initial
Exercise Date&#8221;) 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.</p><span></span>

Plan</b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Since inception, the Company has incurred substantial
operating losses, principally from expenses associated with the Company&#8217;s research and development programs, clinical trials
conducted in connection with the Company&#8217;s product candidates, and applications and submissions to the U.S. Food and Drug
Administration. The Company has not generated significant revenue and have incurred significant net losses in each year since our
inception. As of March 31, 2020, the Company has incurred approximately $296 million of cumulative net losses and we had approximately
$17.5 million in cash, investment securities, interest receivable and receivables from the sale of our State of New Jersey net
operating losses. 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.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">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&#8217;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.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In January 2020, the World Health Organization
(WHO) declared an outbreak of coronavirus, COVID-19, to be a &#8220;Public Health Emergency of International Concern,&#8221; 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 mid-May 2020, has spread to over 100 countries, including the United
States. Governments and businesses around the world have taken unprecedented actions to mitigate the spread of COVID-19, including,
but not limited to, shelter-in-place orders, quarantines, significant restrictions on travel, as well as restrictions that prohibit
many employees from going to work. Uncertainty with respect to the economic impacts of the pandemic has introduced significant
volatility in the financial markets. The Company did not observe significant impacts on its business or results of operations for
the three months ended March 31, 2020 due to the global emergence of COVID-19. While the extent to which COVID-19 impacts the Company&#8217;s
future results will depend on future developments, the pandemic and associated economic impacts could result in a material impact
to the Company&#8217;s future financial condition, results of operations and cash flows.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s 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.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">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&#8217;s financial condition and results of operations, the specific impact is not readily determinable as
of the date of these financial statements.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The actual amount of funds the Company will
need to operate is subject to many factors, some of which are beyond the Company&#8217;s control. These factors include the following:</p>

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&#8217;s shares or debt,
the sale of the Company&#8217;s State of New Jersey net operating losses 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.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">During 2019 and 2018, the Company submitted
applications to sell a portion of the Company&#8217;s State of New Jersey net operating losses 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
State of New Jersey net operating losses recognizing a tax benefit for the year ended December 31, 2019 for the net proceeds (approximately
$1.8 million). In early 2020, the Company entered into an agreement to sell these net operating losses, In April of 2020, the Company
completed the sale of the New Jersey net operating losses and received the $1.8 million net proceeds. 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 $2.0 million available in future tax benefits remaining under the NOL Program for future years.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In June 2018, the Company entered into the
Horizon Credit Agreement with Horizon that provided $10 million in new capital. 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.
Payments under the loan agreement are interest only (calculated based on one-month LIBOR plus 7.625%) for the first twenty-four
(24) months after through July 2020, closing, followed by a 24-month amortization period of principal and interest starting on
August 1, 2020 and ending through the scheduled maturity date. On May 13, 2020, the Company and Horizon agreed to defer the first
two principal payments totaling $833,333 due in August and September 2020.</p>

the Company&#8217;s New Jersey NOL&#8217;s as well as the remaining availability under the Capital-on-Demand Equity Facility with
JonesTrading Institutional Services LLC, the Company believes it has sufficient capital resources to fund its operations through
mid-2021.&#160;</p><span></span>

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:</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 0.5in; text-align: justify">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;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 0.5in; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 0.5in; text-align: justify">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</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 0.5in; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 0.5in; text-align: justify">Level 3: Significant unobservable
inputs that reflect a reporting entity&#8217;s own assumptions that market participants would use in pricing an asset or liability.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Cash and cash equivalents, 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 are determined by relying on the securities&#8217;
relationship to other benchmark quoted securities and classified its investments as Level 2 items at March 31, 2020 and December
31, 2019. 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 thee-month period ended March 31, 2020 or during the year ended December 31, 2019. 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&#38;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 13). The in-process R&#38;D is valued using a multi-period excess
earnings method (see Note 8).</p>

are summarized below:</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><b>Note 15. Leases</b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In 2011, the Company executed a lease (the
&#8220;Lease&#8221;) 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 1<sup>st</sup> 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 1<sup>st</sup> 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 1<sup>st</sup>
Lease Amendment and must provide the landlord notice by the 28<sup>th</sup> month of the lease. Effective January 9, 2019, the
Company amended the current terms of the 1<sup>st</sup> 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 2<sup>nd</sup>
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 2<sup>nd</sup> Lease Amendment.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">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.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">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 Condensed
Consolidated Balance Sheet but had no impact on our condensed 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 2<sup>nd</sup> 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.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Basic loss per share is calculated based upon
the net loss available to common shareholders divided by the weighted average number of common shares outstanding during the period.
Diluted loss per share is calculated after adjusting the denominator of the basic earnings per share computation for the effects
of all dilutive potential common shares outstanding during the period. The dilutive effects of preferred stock, options and warrants
and their equivalents are computed using the treasury stock method.</p>

issuable upon exercise of warrants, stock option grants and equity awards were 7,982,990 and 5,412,554 shares for the three-month
periods ended March 31, 2020 and 2019, respectively. Warrants with an exercise price of $0.01 (as more fully described in Note
13) exercisable for 200,000 shares of common stock were considered issued in calculating basic loss per share. For the three-month
periods ended March 31, 2020 and 2019, diluted loss per common share was the same as basic loss per common share as the other warrants
and equity awards that were convertible into shares of the Company&#8217;s common stock were excluded from the calculation of diluted
loss per common share as their effect would have been anti-dilutive.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Celsion Corporation (&#8220;Celsion&#8221;
and the &#8220;Company&#8221;) is a fully integrated development stage oncology drug company focused on advancing a portfolio
of innovative cancer treatments, including directed chemotherapies, DNA-mediated immunotherapy and RNA based therapies. Our lead
product candidate is ThermoDox<sup>&#174;</sup>, a proprietary heat-activated liposomal encapsulation of doxorubicin, currently
in a Phase III clinical trial for the treatment of primary liver cancer (the &#8220;OPTIMA Study&#8221;). Second in our pipeline
is GEN-1, a DNA-mediated immunotherapy for the localized treatment of ovarian cancer. These investigational products are based
on our two platform technologies which, in addition, provide the basis for the future development of a range of therapeutics for
difficult-to-treat forms of cancer. Our first platform is Lysolipid Thermally Sensitive Liposomes, a heat sensitive liposomal
based dosage form that targets disease with known therapeutics in the presence of mild heat. Our second is TheraPlas, a novel
nucleic acid-based treatment for local transfection of therapeutic plasmids. With 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.</p><span></span>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The accompanying unaudited condensed consolidated
financial statements, which include the accounts of the Company and its wholly owned subsidiary, CLSN Laboratories, Inc, have been
prepared in accordance with generally accepted accounting principles in the United States (GAAP) for interim financial information
and with the instructions to Form 10-Q and Article 10 of Regulation S-X. All significant intercompany balances and transactions
have been eliminated in consolidation. Certain information and disclosures normally included in financial statements prepared in
accordance with GAAP have been condensed or omitted pursuant to such rules and regulations.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In the opinion of management, all adjustments,
consisting only of normal recurring accruals considered necessary for a fair presentation, have been included in the accompanying
unaudited condensed consolidated financial statements. Operating results for the three-month period March 31, 2020 and 2019 are
not necessarily indicative of the results that may be expected for any other interim period(s) or for any full year. For further
information, refer to the financial statements and notes thereto included in the Company&#8217;s Annual Report on Form 10-K for
the fiscal year ended December 31, 2019 filed with the Securities and Exchange Commission (SEC) on March 25, 2020.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">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&#8217;s financial statements and accompanying notes. Actual results could differ materially from those estimates. Events
and conditions arising subsequent to the most recent balance sheet date have been evaluated for their possible impact on the financial
statements and accompanying notes. With the recent introduction of the COVID-19 pandemic to the United States, the Company continues
to monitor the impact of this pandemic on its financial condition and results of operations, along with the valuation of its long-term
assets, intangible assets, and goodwill. &#160;The effect of this matter could potentially have an impact on the valuation of
such assets in the future. The COVID-19 matter is discussed in more detail in Note 3 to the financial statements.</p><span></span>

in Note 3, the Company completed the sale of its State of New Jersey net operating loss and received the $1.8 million in proceeds
from the sale in April 2020.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white">On April 23, 2020,
we filed a Current Report on Form 8-K announcing we entered into a loan agreement with Silicon Valley Bank (the &#8220;PPP Loan&#8221;),
pursuant to the Paycheck Protection Program of the Coronavirus Aid, Relief, and Economic Security Act. We thereafter received proceeds
of $632,220 under the PPP Loan. The PPP Loan application required Celsion to certify that there was economic uncertainty surrounding
the Company and that, as such, the PPP Loan was necessary to support our ongoing operations. Celsion made this certification in
good faith after analyzing, among other things, its financial situation and access to alternative forms of capital, and believes
that the Company satisfied all eligibility criteria for the PPP Loan, and that our receipt of the PPP Loan proceeds was consistent
with the broad objectives of the PPP of the CARES Act. The certification given with respect to the PPP Loan does not contain any
objective criteria and is subject to interpretation. In light of subsequent guidance issued by the U.S. Small Business Administration
in consultation with the U.S. Department of the Treasury, out of an abundance of caution we returned the
proceeds of the PPP Loan in full on May 13, 2020. Celsion may choose to reapply for the loan if the SBA provides future applicable
guidance.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Investments in debt securities available for
sale with a fair value of $9,887,455 and $7,985,886 as of March 31, 2020 and December 31, 2019, 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&#8217; equity in accumulated other comprehensive loss.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Investments in debt securities available for
sale are evaluated periodically to determine whether a decline in their value is other than temporary. The term &#8220;other than
temporary&#8221; 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.</p>
