Our Business Overview

We are a late-stage biopharmaceutical company focused on developing and commercializing products to treat rare diseases where there is an unmet medical
need. We maintain two active business segments: BioTherapeutics and Vaccines/BioDefense.

Our BioTherapeutics business segment is developing a novel photodynamic therapy (SGX301) utilizing topical synthetic hypericin activated with safe visible
fluorescent light for the treatment of cutaneous T-cell lymphoma (“CTCL”), our first-in-class innate defense regulator technology, dusquetide (SGX942) for
the  treatment  of  oral  mucositis  in  head  and  neck  cancer,  and  proprietary  formulations  of  oral  beclomethasone  17,21-dipropionate  (“BDP”)  for  the
prevention/treatment  of  gastrointestinal  (“GI”)  disorders  characterized  by  severe  inflammation,  including  pediatric  Crohn’s  disease  (SGX203)  and  acute
radiation enteritis (SGX201).

Our  Vaccines/BioDefense  business  segment  includes  active  development  programs  for  RiVax®,  our  ricin  toxin  vaccine  candidate  and  SGX943,  our
therapeutic candidate for antibiotic resistant and emerging infectious disease. The development of our vaccine programs currently is supported by our heat
stabilization technology, known as ThermoVax®, under existing and on-going government contract funding. With the government contract from the National
Institute of Allergy and Infectious Diseases (“NIAID”), we will attempt to advance the development of RiVax® to protect against exposure to ricin toxin..

An outline of our business strategy follows:

● Following positive interim analysis, complete enrollment and report final results in our pivotal Phase 3 clinical trial of SGX301 for the treatment of

CTCL;

● Continue enrollment of the pivotal Phase 3 clinical trial of SGX942 for the treatment of oral mucositis in head and neck cancer;

● Continue development of RiVax® in combination with our ThermoVax® technology to develop a new heat stable vaccine in biodefense with NIAID

funding support;

● Continue to apply for and secure additional government funding for each of our BioTherapeutics and Vaccines/BioDefense programs through grants,

contracts and/or procurements;

● Pursue business development opportunities for our pipeline programs, as well as explore merger/acquisition strategies; and

● Acquire or in-license new clinical-stage compounds for development.

BioTherapeutics Overview

SGX301 – for Treating Cutaneous T-Cell Lymphoma

SGX301 is a novel, first-in-class, photodynamic therapy that utilizes safe visible light for activation. The active ingredient in SGX301 is synthetic hypericin,
a  photosensitizer  which  is  topically  applied  to  skin  lesions  and  then  activated  by  fluorescent  light  16  to  24  hours  later.  Hypericin  is  also  found  in  several
species of Hypericum plants, although the drug used in SGX301 is chemically synthesized by a proprietary manufacturing process and not extracted from
plants. Importantly, hypericin is optimally activated with visible light thereby avoiding the negative consequences of ultraviolet light. Other light therapies
using UVA light result in serious adverse effects including secondary skin cancers.

Combined  with  photoactivation,  in  clinical  trials  synthetic  hypericin  has  demonstrated  significant  anti-proliferative  effects  on  activated  normal  human
lymphoid cells and inhibited growth of malignant T-cells isolated from CTCL patients. In both settings, it appears that the mode of action is an induction of
cell death in a concentration as well as a light dose-dependent fashion. These effects appear to result, in part, from the generation of singlet oxygen during
photoactivation of hypericin.

Hypericin is one of the most efficient known generators of singlet oxygen, the key component for phototherapy. The generation of singlet oxygen induces
necrosis and apoptosis in adjacent cells. The use of topical synthetic hypericin coupled with directed visible light results in generation of singlet oxygen only
at the treated site. We believe that the use of visible light (as opposed to cancer-causing ultraviolet light) is a major advance in photodynamic therapy. In a
published  Phase  2  clinical  study  in  CTCL,  after  six  weeks  of  twice  weekly  therapy,  a  majority  of  patients  experienced  a  statistically  significant  (p<0.04)
improvement with SGX301 whereas the placebo was ineffective: 58.3% compared to 8.3%, respectively.

SGX301 has received Orphan Drug designation as well as Fast Track designation from the U.S. Food and Drug Administration (“FDA”). The Orphan Drug
Act  is  intended  to  assist  and  encourage  companies  to  develop  safe  and  effective  therapies  for  the  treatment  of  rare  diseases  and  disorders.  In  addition  to
providing a seven-year term of market exclusivity for SGX301 upon final FDA approval, Orphan Drug designation also positions us to be able to leverage a
wide  range  of  financial  and  regulatory  benefits,  including  government  grants  for  conducting  clinical  trials,  waiver  of  FDA  user  fees  for  the  potential
submission of a New Drug Application (“NDA”) for SGX301, and certain tax credits. In addition, Fast Track is a designation that the FDA reserves for a drug
intended to treat a serious or life-threatening condition and one that demonstrates the potential to address an unmet medical need for the condition. Fast Track
designation is designed to facilitate the development and expedite the review of new drugs. For instance, should events warrant, we will be eligible to submit
a NDA for SGX301 on a rolling basis, permitting the FDA to review sections of the NDA prior to receiving the complete submission. Additionally, NDAs for
Fast  Track  development  programs  ordinarily  will  be  eligible  for  priority  review.  SGX301  for  the  treatment  of  CTCL  also  was  granted  Orphan  Drug
designation  from  the  European  Medicines  Agency  (“EMA”)  Committee  for  Orphan  Medical  Products  and  Promising  Innovative  Medicine  (“PIM”)
designation from the Medicines and Healthcare Products Regulatory Agency (“MHRA”) in the United Kingdom (“UK”).

In  August  2018,  the  United  States  Patent  Office  granted  us  a  patent  titled  “Systems  and  Methods  for  Producing  Synthetic  Hypericin”  for  the  unique
proprietary process manufacturing the highly purified form of synthetic hypericin, the active pharmaceutical ingredient in SGX301.

We initiated our pivotal Phase 3 clinical study of SGX301 for the treatment of CTCL during December 2015. This trial, referred to as the “FLASH” study
(Fluorescent Light Activated Synthetic Hypericin), aims to evaluate the response to SGX301 as a skin directed therapy to treat early stage CTCL. We are
actively enrolling patients with approximately 35 CTCL centers across the United States (“U.S.”) participating in this pivotal trial. The Phase 3 protocol is a
highly powered, double-blind, randomized, placebo-controlled, multicenter trial and seeks to enroll approximately 120 evaluable subjects. The trial consists
of three treatment cycles, each of eight weeks duration. Treatments are administered twice weekly for the first six weeks and treatment response is determined
at the end of the eighth week. In the first treatment cycle, approximately 80 subjects receive SGX301 and 40 receive placebo treatment of their index lesions.
In the second cycle, all subjects receive SGX301 treatment of their index lesions, and in the third cycle all subjects receive SGX301 treatment of all of their
lesions. The majority of subjects enrolled to date have elected to continue into the third optional, open-label cycle of the study. We continue to work closely
with the Cutaneous Lymphoma Foundation, as well as the National Organization for Rare Disorders. Subjects are followed for an additional six months after
their  last  evaluation  visit. The  primary  efficacy  endpoint  is  assessed  on  the  percentage  of  patients  in  each  of  the  two  treatment  groups  (i.e.,  SGX301  and
placebo) achieving a partial or complete response of the treated lesions, defined as a ≥ 50% reduction in the total Composite Assessment of Index Lesion
Disease  Severity  (“CAILS”)  score  for  three  index  lesions  at  the  Cycle  1  evaluation  visit  (Week  8)  compared  to  the  total  CAILS  score  at  baseline.  Other
secondary measures assess treatment response including duration, degree of improvement, time to relapse and safety.

During September 2017, the National Cancer Institute (“NCI”), part of the National Institutes of Health (“NIH”) awarded us a Small Business Innovation
Research (“SBIR”) grant of approximately $1.5 million over two years to support the conduct of our pivotal, Phase 3, randomized, double-blind, placebo-
controlled study evaluating SGX301 (synthetic hypericin) as a treatment for CTCL.

During  October  2018,  an  Independent  Data  Monitoring  Committee  (“DMC”)  completed  an  unblinded  interim  analysis  with  data  from  approximately  100
subjects,  including  an  assessment  of  the  Phase  3  FLASH  study’s  primary  efficacy  endpoint.  The  DMC  provided  a  positive  recommendation  to  randomize
approximately 40 additional subjects into the trial to maintain the rigorous assumption of 90% statistical power for the primary efficacy endpoint. No safety
concerns were reported by the DMC based on the interim analysis.

We estimate the potential worldwide market for SGX301 is in excess of $250 million for all applications, including the treatment of CTCL. This potential
market  information  is  a  forward-looking  statement,  and  investors  are  urged  not  to  place  undue  reliance  on  this  statement.  While  we  have  determined  this
potential market size based on assumptions that we believe are reasonable, there are a number of factors that could cause our expectations to change or not be
realized.

Cutaneous T-Cell Lymphoma

CTCL is a class of non-Hodgkin’s lymphoma (“NHL”), a type of cancer of the white blood cells that are an integral part of the immune system. Unlike most
NHLs, which generally involve B-cell lymphocytes (involved in producing antibodies), CTCL is caused by an expansion of malignant T-cell lymphocytes
(involved  in  cell-mediated  immunity)  normally  programmed  to  migrate  to  the  skin.  These  skin-trafficking  malignant  T-cells  migrate  to  the  skin,  causing
various lesions to appear that may change shape as the disease progresses, typically beginning as a rash and eventually forming plaques and tumors. Mycosis
fungoides (“MF”) is the most common form of CTCL. It generally presents with skin involvement only, manifested as scaly, erythematous patches. Advanced
disease  with  diffuse  lymph  node  and  visceral  organ  involvement  is  usually  associated  with  a  poorer  response  rate  to  standard  therapies.  A  relatively
uncommon  sub-group  of  CTCL  patients  present  with  extensive  skin  involvement  and  circulating  malignant  cerebriform  T-cells,  referred  to  as  Sézary
syndrome. These patients have substantially graver prognoses (expected five-year survival rate of 24%), than those with MF (expected five-year survival rate
of 88%).

CTCL  mortality  is  related  to  stage  of  disease,  with  median  survival  generally  ranging  from  about  12  years  in  the  early  stages  to  only  2.5  years  when  the
disease  has  advanced.  There  is  currently  no  FDA-approved  drug  for  front-line  treatment  of  early  stage  CTCL.  Treatment  of  early-stage  disease  generally
involves  skin-directed  therapies.  One  of  the  most  common  unapproved  therapies  used  for  early-stage  disease  is  oral  5  or  8-methoxypsoralen  (“Psoralen”)
given  with  ultraviolet  A  (“UVA”)  light,  referred  to  as  PUVA,  which  is  approved  for  dermatological  conditions  such  as  disabling  psoriasis  not  adequately
responsive  to  other  forms  of  therapy,  idiopathic  vitiligo  and  skin  manifestations  of  CTCL  in  persons  who  have  not  been  responsive  to  other  forms  of
treatment.  Psoralen  is  a  mutagenic  chemical  that  interferes  with  DNA  causing  mutations  and  other  malignancies.  Moreover,  UVA  is  a  carcinogenic  light
source that when combined with the Psoralen, results in serious adverse effects including secondary skin cancers; therefore, the FDA requires a Black Box
warning for PUVA.

CTCL constitutes a rare group of NHLs, occurring in about 4% of the approximate 500,000 individuals living with NHL. We estimate, based upon review of
historic  published  studies  and  reports  and  an  interpolation  of  data  on  the  incidence  of  CTCL,  that  it  affects  over  20,000  individuals  in  the  U.S.,  with
approximately 2,800 new cases seen annually.

Dusquetide

Dusquetide (research name: SGX94) is an innate defense regulator (“IDR”) that regulates the innate immune system to simultaneously reduce inflammation,
eliminate infection and enhance tissue healing.

Dusquetide is based on a new class of short, synthetic peptides known as IDRs. It has a novel mechanism of action in that it modulates the body’s reaction to
both injury and infection and is both simultaneously anti-inflammatory and anti-infective. IDRs have no direct antibiotic activity but modulate host responses,
increasing  survival  after  infections  with  a  broad  range  of  bacterial  Gram-negative  and  Gram-positive  pathogens  including  both  antibiotic  sensitive  and
resistant  strains,  as  well  as  accelerating  resolution  of  tissue  damage  following  exposure  to  a  variety  of  agents  including  bacterial  pathogens,  trauma  and
chemo- or radiation-therapy. IDRs represent a novel approach to the control of infection and tissue damage via highly selective binding to an intracellular
adaptor protein, sequestosome-1, also known as p62, which has a pivotal function in signal transduction during activation and control of the innate defense
system. Preclinical data indicate that IDRs may be active in models of a wide range of therapeutic indications including life-threatening bacterial infections as
well  as  the  severe  side-effects  of  chemo-  and  radiation-therapy.  Additionally,  due  to  selective  binding  to  p62,  dusquetide  may  have  potential  anti-tumor
action.

Dusquetide has demonstrated efficacy in numerous animal disease models including mucositis, colitis, skin infection and other bacterial infections and has
been evaluated in a double-blind, placebo-controlled Phase 1 clinical trial in 84 healthy volunteers with both single ascending dose and multiple ascending
dose components. Dusquetide was shown to have a good safety profile and be well-tolerated in all dose groups when administered by IV over 7 days and was
consistent  with  safety  results  seen  in  pre-clinical  studies.  We  believe  that  market  opportunities  for  dusquetide  include,  but  are  not  limited  to,  oral  and
gastrointestinal  mucositis,  acute  Gram-positive  bacterial  infections  (e.g.,  methicillin  resistant  Staphylococcus  aureus  (MRSA)),  acute  Gram-negative
infections (e.g., acinetobacter, melioidosis), and acute radiation syndrome.

SGX942 – for Treating Oral Mucositis in Head and Neck Cancer

SGX942 is our product candidate containing our IDR technology, dusquetide, targeting the treatment of oral mucositis in head and neck cancer patients. Oral
mucositis in this patient population is an area of unmet medical need where there are currently no approved drug therapies. Accordingly, we received Fast
Track designation for the treatment of oral mucositis as a result of radiation and/or chemotherapy treatment in head and neck cancer patients from the FDA. In
addition, dusquetide has been granted PIM designation in the UK by the MHRA for the treatment of severe oral mucositis in head and neck cancer patients
receiving chemoradiation therapy. The U.S. Patent and Trademark Office and the European Patent Office granted us the patent titled “Novel Peptides and
Analogs for Use in the Treatment of Oral Mucositis” on August 16, 2016 and January 23, 2019, respectively. The newly issued patent claims therapeutic use
of dusquetide and related IDR analogs, and adds to composition of matter claims for dusquetide and related analogs that have been granted in the U.S. and
worldwide.

We initiated a Phase 2 clinical study of SGX942 for the treatment of oral mucositis in head and neck cancer patients in December of 2013. We completed
enrollment in this trial in the second half of 2015, and in December 2015 released positive preliminary results. In this Phase 2 proof-of-concept clinical study
that enrolled 111 patients, SGX942, at a dose of 1.5 mg/kg, successfully reduced the median duration of severe oral mucositis by 50%, from 18 days to 9 days
(p=0.099) in all patients and by 67%, from 30 days to 10 days (p=0.040) in patients receiving the most aggressive chemoradiation therapy for treatment of
their head and neck cancer. The p-values met the prospectively defined statistical threshold of p<0.1 in the study protocol. A less severe occurrence of oral
mucositis, ulcerative oral mucositis (defined as oral mucositis with a WHO score ≥2 corresponding to the occurrence of overt ulceration in the mouth), was
also monitored during the study. In the patients receiving the most aggressive chemoradiation therapy, the median duration of oral mucositis was found to
decrease from 65 days in the placebo treated patients to 51 days in the patients treated with SGX942 1.5 mg/kg (p=0.099).

In addition to identifying the best dose of 1.5 mg/kg, this study achieved all objectives, including increased incidence of “complete response” of tumor at the
one month follow-up visit (47% in placebo vs. 63% in SGX942 at 1.5 mg/kg). Decreases in mortality and decreases in infection rate were also observed with
SGX942 treatment, consistent with the preclinical results observed in animal models.

SGX942 was found to be generally safe and well tolerated, consistent with the safety profile observed in the prior Phase 1 study conducted in 84 healthy
volunteers. The long-term (12 month) follow-up data was consistent with the preliminary positive safety and efficacy findings. While the placebo population
experienced the expected 12-month survival rate of approximately 80%, as defined in the Surveillance, Epidemiology, and End Results statistics 1975-2012
from the National Cancer Institute, the SGX942 1.5 mg/kg treatment group reported a 12-month survival rate of 93% (7% mortality in the SGX942 1.5 mg/kg
group compared to 19% in the placebo group). Similarly, tumor resolution (complete response) at 12 months was better in the SGX942 1.5 mg/kg treatment
group  relative  to  the  placebo  population  (80%  in  the  1.5  mg/kg  group  compared  to  74%  in  the  placebo  group).  Moreover,  in  the  patients  receiving
chemotherapy every third week, the SGX942 1.5 mg/kg treatment group had a tumor resolution rate (complete response) of 82% throughout the 12 months
following  chemoradiation  therapy,  while  the  placebo  group  experienced  a  64%  complete  response  rate.  The  long-term  follow-up  results  from  the  Phase  2
study are reviewed in “Dusquetide: Reduction in Oral Mucositis associated with Enduring Ancillary Benefits in Tumor Resolution and Decreased Mortality in
Head and Neck Cancer Patients” published online in Biotechnology Reports and available at the following link: https://doi.org/10.1016/j.btre.2017.05.002. In
addition to safety, evaluations of other secondary efficacy endpoints, such as the utilization of opioid pain medication, indicated that the SGX942 1.5mg/kg
treatment group had a 40% decrease in the use of opioids at the later stage of the treatment phase of the trial, when oral mucositis is usually most severe and
expected to increase pain medication use. This was in contrast to the placebo group, which demonstrated a 10% increase in use of opioids over this same
period. Data from this Phase 2 trial was published online in the Journal of Biotechnology. The publication also delineates the supportive nonclinical data in
this indication, demonstrating consistency in the qualitative and quantitative biological response, including dose response, across the nonclinical and clinical
data sets. The results are available at the following link: http://authors.elservier.com/sd/article/S01681656116315668.

On September 9, 2016, we and SciClone Pharmaceuticals, Inc. (“SciClone”) entered into an exclusive license agreement, pursuant to which we granted rights
to  SciClone  to  develop,  promote,  market,  distribute  and  sell  SGX942  in  defined  territories.  Under  the  terms  of  the  license  agreement,  SciClone  will  be
responsible for all aspects of development, product registration and commercialization in the territories, having access to data generated by us. In exchange
for  exclusive  rights,  SciClone  will  pay  us  royalties  on  net  sales,  and  we  will  supply  commercial  drug  product  to  SciClone  on  a  cost-plus  basis,  while
maintaining worldwide manufacturing rights.

We have received clearance from the FDA to advance the pivotal Phase 3 protocol for SGX942 in the treatment of oral mucositis in patients with head and
neck cancer receiving chemoradiation therapy. Additionally, we have received positive Scientific Advice from the EMA for the development of SGX942 as a
treatment  for  oral  mucositis  in  patients  with  head  and  neck  cancer.  The  Scientific  Advice  from  the  EMA  indicates  that  a  single,  double-blind,  placebo-
controlled, multinational, Phase 3 pivotal study, if successful, in conjunction with the Phase 2 dose-ranging study, is generally considered sufficient to support
a marketing authorization application (“MAA”) to the EMA for potential licensure in Europe. The advice also provided several suggestions to strengthen the
study  design  and  data  collection  that  were  integrated  into  the  final  protocol.  Scientific  Advice  is  offered  by  the  EMA  to  stakeholders  for  clarification  of
questions  arising  during  development  of  medicinal  products.  The  scope  of  Scientific  Advice  is  limited  to  scientific  issues  and  focuses  on  development
strategies rather than pre-evaluation of data to support an MAA. Scientific Advice is legally non-binding and is based on the current scientific knowledge
which may be subject to future changes.

We are working with leading oncology centers, a number of which participated in the Phase 2 study, to advance this Phase 3 clinical trial referred to as the
“DOM–INNATE” study (Dusquetide treatment in Oral Mucositis – by modulating INNATE immunity). Based on the positive and previously published Phase
2  results  (Study  IDR-OM-01),  the  pivotal  Phase  3  clinical  trial  (Study  IDR-OM-02)  is  a  highly  powered,  double-blind,  randomized,  placebo-controlled,
multinational trial that will seek to enroll approximately 190 subjects with squamous cell carcinoma of the oral cavity and oropharynx who are scheduled to
receive a minimum total cumulative radiation dose of 55 Gy fractionated as 2.0-2.2 Gy per day with concomitant cisplatin chemotherapy given as a dose of
80-100 mg/m2 every  third  week.  Subjects  are  randomized  to  receive  either  1.5  mg/kg  SGX942  or  placebo  given  twice  a  week  during  and  for  two  weeks
following  completion  of  chemoradiation  therapy  (“CRT”).  The  primary  endpoint  for  the  study  is  the  median  duration  of  severe  oral  mucositis,  which  is
assessed by oral examination at each treatment visit and then through six weeks following completion of CRT. Oral mucositis is evaluated using the WHO
Grading system. Severe oral mucositis is defined as a WHO Grade of ≥3. Subjects are followed for an additional 12 months after the completion of treatment.

During July 2017, we initiated our pivotal Phase 3 study with a controlled roll-out of U.S. study sites, followed by the addition of European centers in 2018.
We  anticipate  that  approximately  fifty  U.S.  and  European  oncology  centers  will  be  participating  in  this  pivotal  Phase  3  study.  We  anticipate  an  interim
analysis report from an independent data monitoring committee to be available in the third quarter of 2019.

During September 2017, the National Institute of Dental and Craniofacial Research (“NIDCR”), part of the NIH, awarded us a SBIR grant of approximately
$1.5  million  over  two  years  to  support  the  conduct  of  our  Phase  3,  multinational,  randomized,  double-blind,  placebo-controlled  study  evaluating  SGX942
(dusquetide) as a treatment for severe oral mucositis in patients with head and neck cancer receiving CRT.

We  estimate  the  potential  worldwide  market  for  SGX942  is  in  excess  of  $500  million  for  all  applications,  including  the  treatment  of  oral  mucositis.  This
potential market information is a forward-looking statement, and investors are urged not to place undue reliance on this statement. While we have determined
this potential market size based on assumptions that we believe are reasonable, there are a number of factors that could cause our expectations to change or
not be realized.

Oral Mucositis

Mucositis is the clinical term for damage done to the mucosa by anticancer therapies. It can occur in any mucosal region, but is most commonly associated
with  the  mouth,  followed  by  the  small  intestine.  We  estimate,  based  upon  our  review  of  historic  studies  and  reports,  and  an  interpolation  of  data  on  the
incidence  of  mucositis,  that  mucositis  affects  approximately  500,000  people  in  the  U.S.  per  year  and  occurs  in  40%  of  patients  receiving  chemotherapy.
Mucositis can be severely debilitating and can lead to infection, sepsis, the need for parenteral nutrition and narcotic analgesia. The GI damage causes severe
diarrhea. These symptoms can limit the doses and duration of cancer treatment, leading to sub-optimal treatment outcomes.

The mechanisms of mucositis have been extensively studied and have been linked to the interaction of chemotherapy and/or radiation therapy with the innate
defense system. Bacterial infection of the ulcerative lesions is regarded as a secondary consequence of dysregulated local inflammation triggered by therapy-
induced cell death, rather than as the primary cause of the lesions.

We estimate, based upon our review of historic studies and reports, and an interpolation of data on the incidence of oral mucositis, that oral mucositis is a
subpopulation of approximately 90,000 patients in the U.S., with a comparable number in Europe. Oral mucositis almost always occurs in patients with head
and  neck  cancer  treated  with  radiation  therapy  (greater  than  80%  incidence  of  severe  mucositis)  and  is  common  in  patients  undergoing  high  dose
chemotherapy and hematopoietic cell transplantation, where the incidence and severity of oral mucositis depends greatly on the nature of the conditioning
regimen used for myeloablation.

Oral BDP

Oral  BDP  (beclomethasone  17,21-dipropionate)  represents  a  first-of-its-kind  oral,  locally  acting  therapy  tailored  to  treat  GI  inflammation.  BDP  has  been
marketed  in  the  U.S.  and  worldwide  since  the  early  1970s  as  the  active  pharmaceutical  ingredient  in  a  nasal  spray  and  in  a  metered-dose  inhaler  for  the
treatment  of  patients  with  allergic  rhinitis  and  asthma.  Oral  BDP  is  specifically  formulated  for  oral  administration  as  a  single  product  consisting  of  two
tablets. One tablet is intended to release BDP in the upper sections of the GI tract and the other tablet is intended to release BDP in the lower sections of the
GI tract.

Based  on  its  pharmacological  characteristics,  oral  BDP  may  have  utility  in  treating  other  conditions  of  the  gastrointestinal  tract  having  an  inflammatory
component. We are planning to pursue development programs for the treatment of pediatric Crohn’s disease, acute radiation enteritis and GI ARS pending
further  grant  funding.  We  are  also  exploring  the  possibility  of  testing  oral  BDP  for  local  inflammation  associated  with  ulcerative  colitis,  among  other
indications. 

7

 
 
 
 
 
 
 
 
 
 
 
 
We  estimate  the  potential  worldwide  market  for  oral  BDP  is  in  excess  of  $500  million  for  all  applications,  including  the  treatment  of  pediatric  Crohn’s
disease. This potential market information is a forward-looking statement, and investors are urged not to place undue reliance on this statement. While we
have  determined  this  potential  market  size  based  on  assumptions  that  we  believe  are  reasonable,  there  are  a  number  of  factors  that  could  cause  our
expectations to change or not be realized.

SGX203 – for Treating Pediatric Crohn’s Disease

SGX203  is  a  two  tablet  delivery  system  of  BDP  specifically  designed  for  oral  use  that  allows  for  administration  of  immediate  and  delayed  release  BDP
throughout  the  small  bowel  and  the  colon.  The  FDA  has  given  SGX203  Orphan  Drug  designation  as  well  as  Fast  Track  designation  for  the  treatment  of
pediatric Crohn’s disease. We will pursue a pivotal Phase 3 clinical trial of SGX203 for the treatment of pediatric Crohn’s disease contingent upon additional
funding, such as through partnership funding support.

Pediatric Crohn’s Disease

Crohn’s disease causes inflammation of the GI tract. Crohn’s disease can affect any area of the GI tract, from the mouth to the anus, but it most commonly
affects  the  lower  part  of  the  small  intestine,  called  the  ileum.  The  swelling  caused  by  the  disease  extends  deep  into  the  lining  of  the  affected  organ.  The
swelling can induce pain and can make the intestines empty frequently, resulting in diarrhea. Because the symptoms of Crohn’s disease are similar to other
intestinal  disorders,  such  as  irritable  bowel  syndrome  and  ulcerative  colitis,  it  can  be  difficult  to  diagnose.  People  of  Ashkenazi  Jewish  heritage  have  an
increased risk of developing Crohn’s disease.

Crohn’s disease can appear at any age, but it is most often diagnosed in adults in their 20s and 30s. However, approximately 30% of people with Crohn’s
disease develop symptoms before 20 years of age. We estimate, based upon our review of historic published studies and reports, and an interpolation of data
on the incidence of pediatric Crohn’s disease, that pediatric Crohn’s disease is a subpopulation of approximately 80,000 patients in the U.S. with a comparable
number in Europe. Crohn’s disease tends to be both severe and extensive in the pediatric population and a relatively high proportion (approximately 40%) of
pediatric Crohn’s patients have involvement of their upper gastrointestinal tract.

Crohn’s disease presents special challenges for children and teens. In addition to bothersome and often painful symptoms, the disease can stunt growth, delay
puberty,  and  weaken  bones.  Crohn’s  disease  symptoms  may  sometimes  prevent  a  child  from  participating  in  enjoyable  activities.  The  emotional  and
psychological issues of living with a chronic disease can be especially difficult for young people.

SGX201 – for Preventing Acute Radiation Enteritis

SGX201  is  a  delayed-release  formulation  of  BDP  specifically  designed  for  oral  use.  In  2012,  we  completed  a  Phase  1/2  clinical  trial  testing  SGX201  in
prevention  of  acute  radiation  enteritis.  Patients  with  rectal  cancer  scheduled  to  undergo  concurrent  radiation  and  chemotherapy  prior  to  surgery  were
randomized to one of four dose groups. The objectives of the study were to evaluate the safety and maximal tolerated dose of escalating doses of SGX201, as
well as the preliminary efficacy of SGX201 for prevention of signs and symptoms of acute radiation enteritis. The study demonstrated that oral administration
of SGX201 was safe and well tolerated across all four dose groups. There was also evidence of a potential dose response with respect to diarrhea, nausea and
vomiting  and  the  assessment  of  enteritis  according  to  National  Cancer  Institute  Common  Terminology  Criteria  for  Adverse  Events  for  selected
gastrointestinal  events.  In  addition,  the  incidence  of  diarrhea  was  lower  than  that  seen  in  published  historical  control  data  in  this  patient  population.  This
program was supported in part by a $500,000 two-year SBIR grant awarded by the NIH. We continue to work with our Radiation Enteritis medical advisors to
identify additional funding opportunities to support the clinical development program.

We have received Fast Track designation from the FDA for SGX201 for acute radiation enteritis.

Acute Radiation Enteritis

External radiation therapy is used to treat most types of cancer, including cancer of the bladder, uterine, cervix, rectum, prostate, and vagina. During delivery
of treatment, some level of radiation will also be delivered to healthy tissue, including the bowel, leading to acute and chronic toxicities. The large and small
bowels are very sensitive to radiation and the larger the dose of radiation the greater the damage to normal bowel tissue. Radiation enteritis is a condition in
which the lining of the bowel becomes swollen and inflamed during or after radiation therapy to the abdomen, pelvis, or rectum. Most tumors in the abdomen
and pelvis need large doses, and almost all patients receiving radiation to the abdomen, pelvis, or rectum will show signs of acute enteritis.

Patients with acute enteritis may have nausea, vomiting, abdominal pain and bleeding, among other symptoms. Some patients may develop dehydration and
require hospitalization. With diarrhea, the gastrointestinal tract does not function normally, and nutrients such as fat, lactose, bile salts, and vitamin B12 are
not well absorbed.

Symptoms will usually resolve within two to six weeks after therapy has ceased. Radiation enteritis is often not a self-limited illness, as over 80% of patients
who receive abdominal radiation therapy complain of a persistent change in bowel habits. Moreover, acute radiation injury increases the risk of development
of chronic radiation enteropathy, and overall 5% to 15% of the patients who receive abdominal or pelvic irradiation will develop chronic radiation enteritis.

We estimate, based upon our review of historic published studies and reports, and an interpolation of data on the treatment courses and incidence of cancers
occurring in the abdominal and pelvic regions, there to be over 100,000 patients annually in the U.S., with a comparable number in Europe, who receive
abdominal or pelvic external beam radiation treatment for cancer, and these patients are at risk of developing acute and chronic radiation enteritis.

Vaccines/BioDefense Overview

ThermoVax® – Thermostability Technology

ThermoVax® is a novel method of rendering aluminum salt, (known colloquially as Alum), adjuvanted vaccines stable at elevated temperatures. Alum is the
most widely employed adjuvant technology in the vaccine industry. The value of ThermoVax® lies in its potential ability to eliminate the need for cold chain
production,  transportation,  and  storage  for  Alum  adjuvanted  vaccines.  This  would  relieve  the  high  costs  of  producing  and  maintaining  vaccines  under
refrigerated conditions. Based on historical reports from the World Health Organization and other scientific reports, we believe that a meaningful proportion
of  vaccine  doses  globally  are  wasted  due  to  excursions  from  required  cold  chain  temperature  ranges.  This  is  due  to  the  fact  that  most  Alum  adjuvanted
vaccines need to be maintained at between 2 and 8 degrees Celsius (“C”) and even brief excursions from this temperature range (especially below freezing)
usually necessitates the destruction of the product or the initiation of costly stability programs specific for the vaccine lots in question. ThermoVax® has the
potential to facilitate easier storage and distribution of strategic national stockpile vaccines for ricin exposure in emergency settings.

ThermoVax®  development  was  supported  pursuant  to  our  $9.4  million  NIAID  grant  enabling  development  of  thermo-stable  ricin  (RiVax®)  and  anthrax
(VeloThrax®) vaccines. Proof-of-concept preclinical studies with ThermoVax® indicate that it is able to produce stable vaccine formulations using adjuvants,
protein  immunogens,  and  other  components  that  ordinarily  would  not  withstand  long  temperature  variations  exceeding  customary  refrigerated  storage
conditions.  These  studies  were  conducted  with  our  aluminum-adjuvanted  ricin  toxin  vaccine,  RiVax®  and  our  aluminum-adjuvanted  anthrax  vaccine,
VeloThrax®. Each vaccine was manufactured under precise lyophilization conditions using excipients that aid in maintaining native protein structure of the
key antigen. When RiVax® was kept at 40 degrees C (104 degrees Fahrenheit) for up to one year, all of the animals vaccinated with the lyophilized RiVax®
vaccine developed potent and high titer neutralizing antibodies. In contrast, animals that were vaccinated with the liquid RiVax® vaccine kept at 40 degrees C
did not develop neutralizing antibodies and were not protected against ricin exposure. The ricin A chain is extremely sensitive to temperature and rapidly
loses the ability to induce neutralizing antibodies when exposed to temperatures higher than 8 degrees C. When VeloThrax® was kept for up to 16 weeks at 70
degrees  C,  it  was  able  to  develop  a  potent  antibody  response,  unlike  the  liquid  formulation  kept  at  the  same  temperature.  Moreover,  we  also  have
demonstrated the compatibility of our thermostabilization technology with other secondary adjuvants such as TLR-4 agonists.

We also entered into a collaboration agreement with Axel Lehrer, PhD of the Department of Tropical Medicine, Medical Microbiology and Pharmacology,
John A. Burns School of Medicine, University of Hawaiʻi at Manoa (“UH Manoa”) and Hawaii Biotech, Inc. (“HBI”) to develop a heat stable subunit Ebola
vaccine. Dr. Lehrer, a co-inventor of the Ebola vaccine with HBI, has shown proof of concept efficacy with subunit Ebola vaccines in non-human primates.
The  most  advanced  Ebola  vaccines  involve  the  use  of  vesicular  stomatitis  virus  and  adenovirus  vectors  –  live,  viral  vectors  which  complicate  the
manufacturing, stability and storage requirements. Dr. Lehrer’s vaccine candidate is based on highly purified recombinant protein antigens, circumventing
many  of  these  manufacturing  difficulties.  Dr.  Lehrer  and  HBI  have  developed  a  robust  manufacturing  process  for  the  required  proteins.  Application  of
ThermoVax® may allow for a product that can avoid the need for cold chain distribution and storage, yielding a vaccine ideal for use in both the developed
and developing world. This agreement has expired in accordance with its terms.

On  February  7,  2019,  European  Journal  of  Pharmaceutics  and  Biopharmaceutics  published  a  scientific  article  demonstrating  the  successful
thermostabilization of an Ebola subunit vaccine candidate.

During September 2017, we announced we will be participating in a NIAID Research Project (R01) grant awarded to UH Manoa for the development of a
trivalent  thermostabilized  Ebola  vaccine,  with  our  awarded  funding  of  approximately  $700,000  over  five  years.  Previous  collaborations  demonstrated  the
feasibility of developing a heat stable subunit Ebola vaccine. Under the terms of the subaward, we will continue to support vaccine formulation development
with our proprietary vaccine thermostabilization technology, ThermoVax®. Ultimately, the objective is to produce a thermostable trivalent filovirus vaccine
for protection against Ebola and related diseases, allowing worldwide distribution without the need for cold storage.

On  December  21,  2010,  we  executed  a  worldwide  exclusive  license  agreement  with  the  University  of  Colorado  (“UC”)  for  certain  patents  relating  to
ThermoVax® in all fields of use. In April 2018, the UC delivered a notice of termination of our license agreement based upon our failure to achieve one of the
development milestones: initiation of the Phase 1 clinical trial of the heat stabilization technology by March 31, 2018. After negotiating with the UC, we and
the UC agreed to extend the termination date to October 31, 2018 in order to allow us time to agree upon a potential agreement that would allow us to keep
the rights to, and to continue to develop, the heat stabilization technology or a product candidate containing the heat stabilization technology in our field of
use.

On October 31, 2018, in a series of related transactions, (a) we and the UC agreed to terminate the original license agreement, (b) the UC and VitriVax, Inc.
(“VitriVax”) executed a worldwide exclusive license agreement for the heat stabilization technology for all fields of use, and (c) we and VitriVax executed a
worldwide  exclusive  sublicense  agreement  for  the  heat  stabilization  technology  for  use  in  the  fields  of  ricin  and  Ebola  vaccines.  We  paid  a  $100,000
sublicense fee on the effective date of the sublicense agreement. To maintain the sublicense we are obliged to pay a minimum annual royalty of $20,000 until
first commercial sale of a sublicensed product, upon which point, we shall pay an earned royalty of 2% of net sales subject to a minimum royalty of $50,000
each year. We are also required to pay royalty on any sub-sublicense income based on a declining percentage of all sub-sublicense income calculated within
the contractual period until reaching a minimum of 15% after two years. In addition, we are required to pay VitriVax milestone fees of: (a) $50,000 upon
initiation  of  a  Phase  II  clinical  trial  of  the  sublicensed  product,  (b)  $200,000  upon  regulatory  approval  of  a  sublicensed  product,  and  (c)  $1  million  upon
achieving $10 million in aggregate net sales of a sublicensed product in the U.S. or equivalent. To date none of these milestones have been met.

RiVax® – Ricin Toxin Vaccine

RiVax® is our proprietary vaccine candidate being developed to protect against exposure to ricin toxin and if approved, would be the first ricin vaccine. The
immunogen  in  RiVax®  induces  a  protective  immune  response  in  animal  models  of  ricin  exposure  and  functionally  active  antibodies  in  humans.  The
immunogen consists of a genetically inactivated ricin A chain subunit that is enzymatically inactive and lacks residual toxicity of the holotoxin. RiVax® has
demonstrated statistically significant (p < 0.0001) preclinical survival results, providing 100% protection against acute lethality in an aerosol exposure non-
human  primate  model  (Roy  et  al,  2015,  Thermostable  ricin  vaccine  protects  rhesus  macaques  against  aerosolized  ricin:  Epitope-specific  neutralizing
antibodies correlate with protection, PNAS USA 112:3782-3787), and has also been shown to be well tolerated and immunogenic in two Phase 1 clinical
trials  in  healthy  volunteers.  Results  of  the  first  Phase  1  human  trial  of  RiVax®  established  that  the  immunogen  was  safe  and  induced  antibodies  that  we
believe may protect humans from ricin exposure. The antibodies generated from vaccination, concentrated and purified, were capable of conferring immunity
passively to recipient animals, indicating that the vaccine was capable of inducing functionally active antibodies in humans. The outcome of this study was
published in the Proceedings of the National Academy of Sciences (Vitetta et al., 2006, A Pilot Clinical Trial of a Recombinant Ricin Vaccine in Normal
Humans, PNAS, 103:2268-2273). The second trial which was completed in September 2012 and was sponsored by University of Texas Southwestern Medical
Center (“UTSW”), evaluated a more potent formulation of RiVax® that contained an aluminum adjuvant (Alum). The results of the Phase 1b study indicated
that Alum-adjuvanted RiVax® was safe and well tolerated, and induced greater ricin neutralizing antibody levels in humans than adjuvant-free RiVax®. The
outcomes of this second study were published in the Clinical and Vaccine Immunology (Vitetta et al., 2012, Recombinant Ricin Vaccine Phase 1b Clinical
Trial,  Clin.  Vaccine  Immunol.  10:1697-1699).  We  have  adapted  the  original  manufacturing  process  for  the  immunogen  contained  in  RiVax®  for
thermostability and large scale manufacturing and recent studies have confirmed that the thermostabilized RiVax® formulation enhances the stability of the
RiVax® antigen, enabling storage for at least 1 year at temperatures up to 40°C (104 °F). The program will pursue approval via the FDA “Animal Rule” since
it is not possible to test the efficacy of the vaccine in a clinical study which would expose humans to ricin. Uniform, easily measured and species-neutral
immune correlates of protection that can be measured in humans and animals, and are indicative of animal survival to subsequent ricin challenge, are central
to  the  application  of  the  “Animal  Rule”.  Recent  work  has  identified  such  potential  correlates  of  immune  protection  in  animals  and  work  to  qualify  and
validate these approaches is continuing, with the goal of utilizing these assays in a planned Phase 1/2 clinical trial with the thermostable RiVax® formulation.
During September 2018, we published an extended stability study of RiVax®, showing up to 100% protection in mice after 12 months storage at 40°C (104
°F) as well as identification of a potential in vitro stability indicating assay, critical to adequately confirming the long-term shelf life of the vaccine. We have
entered  into  a  collaboration  with  IDT  Biologika  GmbH  to  scale-up  the  formulation/filling  process  and  continue  development  and  validation  of  analytical
methods  established  at  IDT  to  advance  the  program.  We  also  have  initiated  a  development  agreement  with  Emergent  BioSolutions,  Inc.  to  implement  a
commercially viable, scalable production technology for the RiVax® drug substance protein antigen.

The development of RiVax® has been sponsored through a series of overlapping challenge grants, UC1, and cooperative grants, U01, from the NIH, granted
to us and to UTSW where the vaccine originated. The second clinical trial was supported by a grant from the FDA’s Office of Orphan Products to UTSW. To
date, we and UTSW have collectively received approximately $25 million in grant funding from the NIH for the development of RiVax®. In September 2014,
we entered into a contract with the NIH for the development of RiVax® that would provide up to an additional $24.7 million of funding in the aggregate if
options to extend the contract are exercised by the NIH. The development agreements with Emergent BioSolutions and IDT are specifically funded under this
NIH contract.

During June 2017 NIAID exercised an option for the evaluation of RiVax® to fund additional animal efficacy studies. The exercised option will provide us
with approximately $2.0 million in additional funding. Additionally, during August 2017 NIAID exercised an option to fund good manufacturing practices
compliant RiVax® bulk drug substance and finished drug product manufacturing, which is required for the conduct of future preclinical and clinical safety and
efficacy studies. The exercised option will provide us with approximately $2.5 million in additional non-dilutive funding, bringing the total amount awarded
to date under this contract to $21.2 million, of which $13.5 million is still available. If all contract options are exercised, the total award of up to $24.7 million
will  support  the  preclinical,  manufacturing  and  clinical  development  activities  necessary  to  advance  heat  stable  RiVax®  with  the  FDA.  In  addition  to  the
ongoing funding of up to $24.7 million for the development of RiVax®, biomarkers for RiVax® testing have been successfully identified, facilitating potential
approval under the FDA Animal Rule.

RiVax® has been granted Orphan Drug designation by the FDA for the prevention of ricin intoxication. In addition, RiVax® has also been granted Orphan
Drug designation in the EU from the EMA Committee for Orphan Medical Products.

11

 
 
 
 
 
 
 
Assuming development efforts are successful for RiVax®,  we  believe  potential  government  procurement  contract(s)  could  reach  as  much  as  $200  million.
This potential procurement contract information is a forward-looking statement, and investors are urged not to place undue reliance on this statement. While
we have determined this potential procurement contract value based on assumptions that we believe are reasonable, there are a number of factors that could
cause our expectations to change or not be realized.

As a new chemical entity, an FDA approved RiVax® vaccine has the potential to qualify for a biodefense Priority Review Voucher (“PRV”). Approved under
the 21st Century Cures Act in late 2016, the biodefense PRV is awarded upon approval as a medical countermeasure when the active ingredient(s) have not
been otherwise approved for use in any context. PRVs are transferable and can be sold, with sales in recent years of up to $350 million. When redeemed,
PRVs entitle the user to an accelerated review period of nine months, saving a median of seven months review time as calculated in 2009. However, FDA
must be advised 90 days in advance of the use of the PRV and the use of a PRV is associated with an additional user fee ($2.7 million in 2017).

Ricin Toxin

Ricin toxin can be cheaply and easily produced, is stable over long periods of time, is toxic by several routes of exposure and thus has the potential to be used
as a biological weapon against military and/or civilian targets. As a bioterrorism agent, ricin could be disseminated as an aerosol, by injection, or as a food
supply contaminant. The potential use of ricin toxin as a biological weapon of mass destruction has been highlighted in a Federal Bureau of Investigation
Bioterror report released in November 2007 titled Terrorism 2002-2005, which states that “Ricin and the bacterial agent anthrax are emerging as the most
prevalent agents involved in WMD investigations” (http://www.fbi.gov/stats-services/publications/terrorism-2002-2005/terror02_05.pdf). In recent years, Al
Qaeda  in  the  Arabian  Peninsula  has  threatened  the  use  of  ricin  toxin  to  poison  food  and  water  supplies  and  in  connection  with  explosive  devices.
Domestically,  the  threat  from  ricin  remains  a  concern  for  security  agencies.  In  April  2013,  letters  addressed  to  the  President  of  the  United  States,  a  U.S.
Senator and a judge tested positive for ricin. As recently as October 2018, an envelope addressed to President Trump was suspected to contain this potent and
potentially lethal toxin, which was subsequently confirmed to contain pieces of castor beans used to make ricin.

The  Centers  for  Disease  Control  and  Prevention  has  classified  ricin  toxin  as  a  Category  B  biological  agent.  Ricin  works  by  first  binding  to  glycoproteins
found  on  the  exterior  of  a  cell,  and  then  entering  the  cell  and  inhibiting  protein  synthesis  leading  to  cell  death.  Once  exposed  to  ricin  toxin,  there  is  no
effective therapy available to reverse the course of the toxin. The recent ricin threat to government officials has heightened the awareness of this toxic threat.
Currently, there is no FDA approved vaccine to protect against the possibility of ricin toxin being used in a terrorist attack, or its use as a weapon on the
battlefield nor is there a known antidote for ricin toxin exposure.

OrbeShield® – for Treating GI Acute Radiation Syndrome

OrbeShield® is an oral immediate and delayed release formulation of the topically active corticosteroid BDP and is being developed for the treatment of GI
ARS. Corticosteroids are a widely used class of anti-inflammatory drugs. BDP is a corticosteroid with predominantly topical activity that is approved for use
in asthma, psoriasis and allergic rhinitis.

OrbeShield®  has  demonstrated  positive  preclinical  results  in  a  canine  GI  ARS  model  which  indicate  that  dogs  treated  with  OrbeShield®  demonstrated
statistically significant (p=0.04) improvement in survival with dosing at either two hours or 24 hours after exposure to lethal doses of total body irradiation
(“TBI”) when compared to control dogs. OrbeShield® appears to significantly mitigate the damage to the GI epithelium caused by exposure to high doses of
radiation using a well-established canine model of GI ARS.

The GI tract is highly sensitive to ionizing radiation and the destruction of epithelial tissue is one of the first effects of radiation exposure. The rapid loss of
epithelial cells leads to inflammation and infection that are often the primary cause of death in acute radiation injury. This concept of GI damage also applies
to the clinical setting of oncology, where high doses of radiation cannot be administered effectively to the abdomen because radiation is very toxic to the
intestines.  We  are  seeking  to  treat  the  same  type  of  toxicity  in  our  acute  radiation  enteritis  clinical  program  with  SGX201.  As  a  result,  we  believe  that
OrbeShield® has the potential to be a “dual use” compound, a desirable characteristic which is a specific priority for ARS and other medical countermeasure
indications.

In September 2013, we received two government contracts from the Biomedical Advanced Research and Development Authority (“BARDA”) and NIAID for
the advanced preclinical and manufacturing development of OrbeShield® leading to FDA approval to treat GI ARS. The BARDA contract contained a two
year base period with two contract options, exercisable by BARDA, for a total of five years and up to $26.3 million. The NIAID contract consisted of a one
year base period and two contract options, exercisable by NIAID, for a total of three years and up to $6.4 million. We received a combined approximate $18
million in contract funding from both BARDA and NIAID which includes combined supplemental funding of $634,000, extending the programs through the
first quarter of 2017. The NIAID contract was completed during the first quarter of 2017 along with the expiration of the base period of the BARDA contract
for  the  development  of  OrbeShield®,  with  BARDA  electing  not  to  extend  the  current  contract  beyond  the  base  period.  We  will  continue  to  apply  for
additional government funding. Previously, development of OrbeShield® had been largely supported by a $1 million NIH grant to our academic partner, the
Fred Hutchinson Cancer Research Center. In July 2012, we received an SBIR grant from NIAID of approximately $600,000 to support further preclinical
development of OrbeShield® for the treatment of acute GI ARS. The FDA has given OrbeShield® Orphan Drug designation and Fast Track designation for
the prevention of death following a potentially lethal dose of total body irradiation during or after a radiation disaster.

Assuming development efforts are successful for OrbeShield®, we believe potential government procurement contracts could reach as much as $450 million.
This potential procurement contract information is a forward-looking statement, and investors are urged not to place undue reliance on this statement. While
we have determined this potential procurement contract value based on assumptions that we believe are reasonable, there are a number of factors that could
cause our expectations to change or not be realized.

GI Acute Radiation Syndrome

ARS occurs after toxic radiation exposure and involves several organ systems, notably the bone marrow, the GI tract and later the lungs. In the event of a
nuclear  disaster  or  terrorist  detonation  of  a  nuclear  bomb,  casualties  exposed  to  greater  than  2  grays  (“Gy”)  of  absorbed  radiation  are  at  high  risk  for
development of clinically significant ARS. Exposure to high doses of radiation exceeding 10-12 Gy causes acute GI injury which can result in death. The GI
tract is highly sensitive due to the continuous need for crypt stem cells and production of mucosal epithelium. The extent of injury to the bone marrow and the
GI  tract  are  the  principal  determinants  of  survival  after  exposure  to  TBI.  Although  the  hematopoietic  syndrome  can  be  rescued  by  bone  marrow
transplantation  or  growth  factor  administration,  there  is  no  established  treatment  or  preventive  measure  for  the  GI  damage  that  occurs  after  high-dose
radiation. As a result, we believe there is an urgent medical need for specific medical counter measures against the lethal pathophysiological manifestations of
radiation-induced GI injury.

SGX943 – for Treating Emerging and/or Antibiotic-Resistant Infectious Diseases

SGX943 is an IDR, containing the same active ingredient as SGX942. Dusquetide is a fully synthetic, 5-amino acid peptide with high aqueous solubility and
stability. Extensive in vivo preclinical studies have demonstrated enhanced clearance of bacterial infection with SGX943 administration. SGX943 has shown
efficacy against both Gram-negative and Gram-positive bacterial infections in preclinical models, independent of whether the bacteria is antibiotic-resistant or
antibiotic-sensitive.

The  innate  immune  system  is  responsible  for  rapid  and  non-specific  responses  to  combat  bacterial  infection.  Augmenting  these  responses  represents  an
alternative approach to treating bacterial infections. In animal models, IDRs are efficacious against both antibiotic-sensitive and antibiotic-resistant infections,
both Gram-positive and Gram-negative bacteria, and are active irrespective of whether the bacteria occupies a primarily extracellular or intracellular niche.
IDRs  are  also  effective  as  stand-alone  agents  or  in  conjunction  with  antibiotics.  An  IDR  for  the  treatment  of  serious  bacterial  infections  encompasses  a
number of clinical advantages including:

● Treatment when antibiotics are contraindicated, such as:

o

o

before the infectious organism and/or its antibiotic susceptibility is known; or

in at-risk populations prior to infection.

13

 
 
 
 
 
 
 
 
 
 
 
 
● An ability to be used as an additive, complementary treatment with antibiotics, thereby:

o

o

o

enhancing efficacy of sub-optimal antibiotic regimens (e.g., partially antibiotic-resistant infections);

enhancing clearance of infection, thereby minimizing the generation of antibiotic resistance (e.g., in treating melioidosis); and

reducing the required antibiotic dose, again potentially minimizing the generation of antibiotic resistance.

● An ability to modulate the deleterious consequences of inflammation in response to the infection, including the inflammation caused by antibiotic-

driven bacterial lysis; and

● Being unlikely to generate bacterial resistance since the IDR acts on the host, and not the pathogen.

Importantly,  systemic  inflammation  and  multi-organ  failure  is  the  ultimate  common  outcome  of  not  only  emerging  and/or  antibiotic-resistant  infectious
diseases, but also of most biothreat agents (e.g., Burkholderia pseudomallei), indicating that dusquetide would be applicable not only to antibiotic-resistant
infection, but also to biothreat agents, especially where the pathogen is not known and/or has been engineered for enhanced antibiotic resistance.

The Drug Approval Process

The  FDA  and  comparable  regulatory  agencies  in  state,  local  and  foreign  jurisdictions  impose  substantial  requirements  on  the  clinical  development,
manufacture and marketing of new drug and biologic products. The FDA, through regulations that implement the Federal Food, Drug, and Cosmetic Act, as
amended (“FDCA”), and other laws and comparable regulations for other agencies, regulate research and development activities and the testing, manufacture,
labeling, storage, shipping, approval, recordkeeping, advertising, promotion, sale, export, import and distribution of such products. The regulatory approval
process is generally lengthy, expensive and uncertain. Failure to comply with applicable FDA and other regulatory requirements can result in sanctions being
imposed on us or the manufacturers of our products, including holds on clinical research, civil or criminal fines or other penalties, product recalls, or seizures,
or total or partial suspension of production or injunctions, refusals to permit products to be imported into or exported out of the United States, refusals of the
FDA to grant approval of drugs or to allow us to enter into government supply contracts, withdrawals of previously approved marketing applications and
criminal prosecutions.

Before human clinical testing in the U.S. of a new drug compound or biological product can commence, an Investigational New Drug (“IND”), application is
required to be submitted to the FDA. The IND application includes results of pre-clinical animal studies evaluating the safety and efficacy of the drug and a
detailed description of the clinical investigations to be undertaken.

Clinical trials are normally done in three phases, although the phases may overlap. Phase 1 trials are smaller trials concerned primarily with metabolism and
pharmacologic actions of the drug and with the safety of the product. Phase 2 trials are designed primarily to demonstrate effectiveness and safety in treating
the disease or condition for which the product is indicated. These trials typically explore various doses and regimens. Phase 3 trials are expanded clinical
trials intended to gather additional information on safety and effectiveness needed to clarify the product’s benefit-risk relationship and generate information
for  proper  labeling  of  the  drug,  among  other  things.  The  FDA  receives  reports  on  the  progress  of  each  phase  of  clinical  testing  and  may  require  the
modification, suspension or termination of clinical trials if an unwarranted risk is presented to patients. When data is required from long-term use of a drug
following its approval and initial marketing, the FDA can require Phase 4, or post-marketing, studies to be conducted.

14

 
 
 
 
 
 
 
 
 
 
 
 
 
With certain exceptions, once successful clinical testing is completed, the sponsor can submit a New Drug Application (“NDA”), for approval of a drug, or a
Biologic License Application (“BLA”), for biologics such as vaccines, which will be reviewed, and if successful, approved by the FDA, allowing the product
to  be  marketed.  The  process  of  completing  clinical  trials  for  a  new  drug  is  likely  to  take  a  number  of  years  and  require  the  expenditure  of  substantial
resources. Furthermore, the FDA or any foreign health authority may not grant an approval on a timely basis, if at all. The FDA may deny the approval of an
NDA or BLA, in its sole discretion, if it determines that its regulatory criteria have not been satisfied or may require additional testing or information. Among
the conditions for marketing approval is the requirement that the prospective manufacturer’s quality control and manufacturing procedures conform to good
manufacturing  practice  regulations.  In  complying  with  standards  contained  in  these  regulations,  manufacturers  must  continue  to  expend  time,  money  and
effort in the area of production, quality control and quality assurance to ensure full technical compliance. Manufacturing facilities, both foreign and domestic,
also are subject to inspections by, or under the authority of, the FDA and by other federal, state, local or foreign agencies.

Even after initial FDA or foreign health authority approval has been obtained, further studies, including Phase 4 post-marketing studies, may be required to
provide additional data on safety and will be required to gain approval for the marketing of a product as a treatment for clinical indications other than those
for which the product was initially tested. For certain drugs intended to treat serious, life-threatening conditions that show great promise in earlier testing, the
FDA can also grant conditional approval. However, drug developers are required to study the drug further and verify clinical benefit as part of the conditional
approval  provision,  and  the  FDA  can  revoke  approval  if  later  testing  does  not  reproduce  previous  findings.  The  FDA  may  also  condition  approval  of  a
product  on  the  sponsor  agreeing  to  certain  mitigation  strategies  that  can  limit  the  unfettered  marketing  of  a  drug.  Also,  the  FDA  or  foreign  regulatory
authority will require post-marketing reporting to monitor the side effects of the drug. Results of post-marketing programs may limit or expand the further
marketing  of  the  product.  Further,  if  there  are  any  modifications  to  the  drug,  including  any  change  in  indication,  manufacturing  process,  labeling  or
manufacturing facility, an application seeking approval of such changes will likely be required to be submitted to the FDA or foreign regulatory authority.

In  the  U.S.,  the  FDCA,  the  Public  Health  Service  Act,  the  Federal  Trade  Commission  Act,  and  other  federal  and  state  statutes  and  regulations  govern,  or
influence the research, testing, manufacture, safety, labeling, storage, record keeping, approval, advertising and promotion of drug, biological, medical device
and  food  products.  Noncompliance  with  applicable  requirements  can  result  in,  among  other  things,  fines,  recall  or  seizure  of  products,  refusal  to  permit
products to be imported into the U.S., refusal of the government to approve product approval applications or to allow us to enter into government supply
contracts,  withdrawal  of  previously  approved  applications  and  criminal  prosecution. The  FDA  may  also  assess  civil  penalties  for  violations  of  the  FDCA
involving medical devices.

For biodefense development, such as with RiVax® and OrbeShield®, the FDA has instituted policies that are expected to result in shorter pathways to market.
This potentially includes approval for commercial use utilizing the results of animal efficacy trials, rather than efficacy trials in humans. However, we will
still  have  to  establish  that  the  vaccine  and  countermeasures  it  is  developing  are  safe  in  humans  at  doses  that  are  correlated  with  the  beneficial  effect  in
animals. Such clinical trials will also have to be completed in distinct populations that are subject to the countermeasures; for instance, the very young and the
very old, and in pregnant women, if the countermeasure is to be licensed for civilian use. Other agencies will have an influence over the benefit-risk scenarios
for deploying the countermeasures and in establishing the number of doses utilized in the Strategic National Stockpile. We may not be able to sufficiently
demonstrate the animal correlation to the satisfaction of the FDA, as these correlates are difficult to establish and are often unclear. Invocation of the animal
rule may raise issues of confidence in the model systems even if the models have been validated. For many of the biological threats, the animal models are not
available and we may have to develop the animal models, a time-consuming research effort. There are few historical precedents, or recent precedents, for the
development  of  new  countermeasure  for  bioterrorism  agents.  Despite  the  animal  rule,  the  FDA  may  require  large  clinical  trials  to  establish  safety  and
immunogenicity  before  licensure  and  it  may  require  safety  and  immunogenicity  trials  in  additional  populations.  Approval  of  biodefense  products  may  be
subject to post-marketing studies, and could be restricted in use in only certain populations.

Vaccines are approved under the BLA process that exists under the Public Health Service Act. In addition to the greater technical challenges associated with
developing biologics, the potential for generic competition is lower for a BLA product than a small molecule product subject to an NDA under the Federal
Food,  Drug  and  Cosmetic  Act.  Under  the  Patient  Protection  and  Affordable  Care  Act  enacted  in  2010,  a  “generic”  version  of  a  biologic  is  known  as  a
biosimilar and the barriers to entry – whether legal, scientific, or logistical – for a biosimilar version of a biologic approved under a BLA are higher.

15

 
 
 
 
 
 
 
Orphan Drug Designation

Under the Orphan Drug Act, the FDA may grant orphan drug designation to drugs or biologics intended to treat a rare disease or condition – generally a
disease or condition that affects fewer than 200,000 individuals in the United States. Orphan drug designation must be requested before submitting an NDA or
BLA. After the FDA grants orphan drug designation, the generic identity of the drug or biologic and its potential orphan use are disclosed publicly by the
FDA. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process. The first NDA or
BLA applicant to receive FDA approval for a particular active ingredient to treat a particular disease with FDA orphan drug designation is entitled to a seven-
year exclusive marketing period in the United States for that product, for that indication. During the seven-year exclusivity period, the FDA may not approve
any other applications to market the same drug or biologic for the same disease, except in limited circumstances, such as a showing of clinical superiority to
the product with orphan drug exclusivity. Orphan drug exclusivity does not prevent the FDA from approving a different drug or biologic for the same disease
or condition, or the same drug or biologic for a different disease or condition. Among the other benefits of orphan drug designation are tax credits for certain
research and a waiver of the NDA or BLA application user fee.

Fast Track Designation and Accelerated Approval

The  FDA  is  required  to  facilitate  the  development,  and  expedite  the  review,  of  drugs  or  biologics  that  are  intended  for  the  treatment  of  a  serious  or  life-
threatening  disease  or  condition  for  which  there  is  no  effective  treatment  and  which  demonstrate  the  potential  to  address  unmet  medical  needs  for  the
condition. Under the fast track program, the sponsor of a new drug or biologic candidate may request that the FDA designate the candidate for a specific
indication as a fast track drug or biologic concurrent with, or after, the filing of the IND for the candidate. The FDA must determine if the drug or biologic
candidate qualifies for fast track designation within 60 days of receipt of the sponsor’s request. Unique to a fast track product, the FDA may initiate review of
sections of a fast track product’s NDA or BLA before the application is complete. This rolling review is available if the applicant provides, and the FDA
approves, a schedule for the submission of the remaining information and the applicant pays applicable user fees. However, the FDA’s time period goal for
reviewing an application does not begin until the last section of the NDA or BLA is submitted. Additionally, the fast track designation may be withdrawn by
the FDA if the FDA believes that the designation is no longer supported by data emerging in the clinical trial process.

Any product submitted to the FDA for marketing, including under a fast track program, may be eligible for other types of FDA programs intended to expedite
development  and  review,  such  as  accelerated  approval.  Drug  or  biological  products  studied  for  their  safety  and  effectiveness  in  treating  serious  or  life-
threatening illnesses and that provide meaningful therapeutic benefit over existing treatments may receive accelerated approval, which means the FDA may
approve the product based upon a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier
than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into
account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments.

In clinical trials, a surrogate endpoint is a measurement of laboratory or clinical signs of a disease or condition that substitutes for a direct measurement of
how a patient feels, functions, or survives. Surrogate endpoints can often be measured more easily or more rapidly than clinical endpoints. A drug or biologic
candidate approved on this basis is subject to rigorous post-marketing compliance requirements, including the completion of Phase 4 or post-approval clinical
trials  to  confirm  the  effect  on  the  clinical  endpoint.  Failure  to  conduct  required  post-approval  studies,  or  confirm  a  clinical  benefit  during  post-marketing
studies, will allow the FDA to withdraw the drug or biologic from the market on an expedited basis. All promotional materials for drug candidates approved
under accelerated regulations are subject to prior review by the FDA.

Pediatric Information

Under  the  Pediatric  Research  Equity  Act  (“PREA”),  NDAs  or  BLAs  or  supplements  to  NDAs  or  BLAs  must  contain  data  to  assess  the  safety  and
effectiveness  of  the  drug  for  the  claimed  indications  in  all  relevant  pediatric  subpopulations  and  to  support  dosing  and  administration  for  each  pediatric
subpopulation  for  which  the  drug  is  safe  and  effective.  The  FDA  may  grant  full  or  partial  waivers,  or  deferrals,  for  submission  of  data.  Unless  otherwise
required by regulation, PREA does not apply to any drug for an indication for which orphan designation has been granted.

Early Access to Medicines Scheme

Launched  in  April  2014  in  the  United  Kingdom  by  the  MHRA,  the  Early  Access  to  Medicines  Scheme  (“EAMS”)  offers  severely  ill  patients  with  life-
threatening and seriously debilitating conditions the lifeline of trying ground-breaking new medicines earlier than they would normally be accessible. PIM
designation is the first phase of EAMS and is awarded following an assessment of early nonclinical and clinical data by the MHRA. The criteria product
candidates must meet to obtain PIM designation are:

● Criterion 1 – The condition should be life-threatening or seriously debilitating with a high unmet medical need (i.e., there is no method of treatment,

diagnosis or prevention available or existing methods have serious limitations).

● Criterion 2 – The medicinal product is likely to offer major advantage over methods currently used in the UK.

● Criterion  3  –  The  potential  adverse  effects  of  the  medicinal  product  are  likely  to  be  outweighed  by  the  benefits,  allowing  for  the  reasonable
expectation  of  a  positive  benefit  risk  balance.  A  positive  benefit  risk  balance  should  be  based  on  preliminary  scientific  evidence  that  the  safety
profile of the medicinal product is likely to be manageable and acceptable in relation to the estimated benefits.

False Claims Laws

The federal False Claims Act prohibits, among other things, any person or entity from knowingly presenting, or causing to be presented, a false claim for
payment to, or approval by, the federal government or knowingly making, using, or causing to be made or used a false record or statement material to a false
or fraudulent claim to the federal government. As a result of a modification made by the Fraud Enforcement and Recovery Act of 2009, a claim includes “any
request or demand” for money or property presented to the U.S. government.

Anti-Kickback Laws

The federal Anti-Kickback Statute prohibits, among other things, any person or entity, from knowingly and willfully offering, paying, soliciting or receiving
any remuneration, directly or indirectly, overtly or covertly, in cash or in kind, to induce or in return for purchasing, leasing, ordering or arranging for the
purchase, lease or order of any item or service reimbursable under Medicare, Medicaid or other federal healthcare programs. The term remuneration has been
interpreted  broadly  to  include  anything  of  value.  The  Anti-Kickback  Statute  has  been  interpreted  to  apply  to  arrangements  between  pharmaceutical
manufacturers on one hand and prescribers, purchasers, and formulary managers on the other.

United States Healthcare Reform

Federal  Physician  Payments  Sunshine  Act  and  its  implementing  regulations  require  that  certain  manufacturers  of  drugs,  devices,  biological  and  medical
supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report information
related to certain payments or other transfers of value made or distributed to physicians and teaching hospitals, or to entities or individuals at the request of, or
designated on behalf of, the physicians and teaching hospitals and to report annually certain ownership and investment interests held by physicians and their
immediate family members.

In addition, we may be subject to data privacy and security regulation by both the federal government and the states in which we conduct our business. The
Health Insurance Portability and Accountability Act (“HIPAA”), as amended by the Health Information Technology for Economic and Clinical Health Act
(“HITECH”), and its implementing regulations, imposes certain requirements relating to the privacy, security and transmission of individually identifiable
health information. Among other things, HITECH makes HIPAA’s privacy and security standards directly applicable to “business associates” – independent
contractors or agents of covered entities that receive or obtain protected health information in connection with providing a service on behalf of a covered
entity. HITECH also created four new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business
associates  and  possibly  other  persons,  and  gave  state  attorneys  general  new  authority  to  file  civil  actions  for  damages  or  injunctions  in  federal  courts  to
enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions. In addition, state laws govern the privacy
and security of health information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus
complicating compliance efforts.

Third-Party Suppliers and Manufacturers

Drug  substance  and  drug  product  manufacturing  is  outsourced  to  qualified  suppliers.  We  do  not  have  manufacturing  capabilities/infrastructure  and  do  not
intend to develop the capacity to manufacture drug products substances. We have agreements with third-party manufacturers to supply bulk drug substances
for  our  product  candidates  and  with  third  parties  to  formulate,  package  and  distribute  our  product  candidates.  Our  employees  include  professionals  with
expertise in pharmaceutical manufacturing development, quality assurance and third party supplier management who oversee work conducted by third-party
companies. We believe that we have on hand or can easily obtain sufficient amounts of product candidates to complete our currently contemplated clinical
trials. All of the drug substances used in our product candidates currently are manufactured by single suppliers. While we have not experienced any supply
disruptions,  the  number  of  manufacturers  of  the  drug  substances  is  limited.  In  the  event  it  is  necessary  or  advisable  to  acquire  supplies  from  alternative
suppliers, assuming commercially reasonable terms could be reached, the challenge would be the efficient transfer of technology and know-how from current
manufactures to the new supplier. Formulation and distribution of our finished product candidates also currently are conducted by single suppliers but we
believe that alternative sources for these services are readily available on commercially reasonable terms, subject to the efficient transfer of technology and
know-how from current suppliers to the new supplier.

All  of  the  current  agreements  for  the  supply  of  bulk  drug  substances  for  our  product  candidates  and  for  the  formulation  or  distribution  of  our  product
candidates relate solely to the development (including preclinical and clinical) of our product candidates. Under these contracts, our product candidates are
manufactured  upon  our  order  of  a  specific  quantity.  In  the  event  that  we  obtain  marketing  approval  for  a  product  candidate,  we  will  qualify  secondary
suppliers for all key manufacturing activities supporting the marketing application.

Marketing and Collaboration

We  do  not  currently  have  any  sales  and  marketing  capability,  other  than  to  potentially  market  our  biodefense  vaccine  products  directly  to  government
agencies.  With  respect  to  other  commercialization  efforts,  we  currently  intend  to  seek  distribution  and  other  collaboration  arrangements  for  the  sales  and
marketing of any product candidate that is approved, while also evaluating the potential to commercialize on our own in orphan disease indications. From
time to time, we have had and are having strategic discussions with potential collaboration partners for our biodefense vaccine product candidates, although
no assurance can be given that we will be able to enter into one or more collaboration agreements for our product candidate on acceptable terms, if at all. We
believe that both military and civilian health authorities of the U.S. and other countries will increase their stockpiling of therapeutics and vaccines to treat and
prevent diseases and conditions that could ensue following a bioterrorism attack.

On December 20, 2012, we re-acquired the North American and European commercial rights to oral BDP through an amendment of our collaboration and
supply  agreement  with  Sigma-Tau  Pharmaceuticals,  Inc.,  which  is  now  known  as  Leadiant  Biosciences,  Inc.  (“Leadiant”).  The  amendment  requires  us  to
make  certain  approval  and  commercialization  milestone  payments  to  Leadiant  which  could  reach  up  to  $6  million.  In  addition,  we  have  agreed  to  pay
Leadiant: (a) a royalty amount equal to 3% of all net sales of oral BDP made directly by us, and any third-party partner and/or their respective affiliates in the
U.S., Canada, Mexico and in each country in the European Territory for the later to occur of: (i) a period of ten years from the first commercial sale of oral
BDP in each country, or (ii) the expiration of our patents and patent applications relating to oral BDP in such country (the “Payment Period”); and (b) 15% of
all  up-front  payments,  milestone  payments  and  any  other  consideration  (exclusive  of  equity  payments)  received  by  us  and/or  a  potential  partner  from  us
and/or potential partner’s licensees, distributors and agents for oral BDP in each relevant country in the territory, which amount will be paid on a product-by-
product and a country-by-country basis for the Payment Period.

On August 25, 2013, we entered into an agreement with SciClone Pharmaceuticals, Inc. (“SciClone”), pursuant to which SciClone provided us with access to
its  oral  mucositis  clinical  and  regulatory  data  library  in  exchange  for  exclusive  commercialization  rights  for  SGX942  in  the  People’s  Republic  of  China,
including Hong Kong and Macau, subject to the negotiation of economic terms. SciClone’s data library was generated from two sequential Phase 2 clinical
studies conducted in 2010 and 2012 evaluating SciClone’s compound, SCV-07, for the treatment of oral mucositis caused by chemoradiation therapy in head
and neck cancer patients, before SciClone terminated its program. By analyzing data available from the placebo subjects in the SciClone trials, we acquired
valuable insight into disease progression, along with quantitative understanding of its incidence and severity in the head and neck cancer patient population.
This information assisted us with the design of the SGX942 Phase 2 clinical trial, in which positive preliminary results were announced in December 2015.

On September 9, 2016, we and SciClone entered into an exclusive license agreement, pursuant to which we granted rights to SciClone to develop, promote,
market, distribute and sell SGX942 in the People’s Republic of China, including Hong Kong and Macau, as well as Taiwan, South Korea and Vietnam. Under
the terms of the license agreement, SciClone will be responsible for all aspects of development, product registration and commercialization in the territory,
having access to data generated by us. In exchange for exclusive rights, SciClone will pay us royalties on net sales, and we will supply commercial drug
product to SciClone on a cost-plus basis, while maintaining worldwide manufacturing rights. We also entered into a common stock purchase agreement with
SciClone  pursuant  to  which  we  sold  352,942  shares  of  our  common  stock  to  SciClone  for  approximately  $8.50  per  share,  for  an  aggregate  price  of
$3,000,000.

Competition

Our  competitors  are  pharmaceutical  and  biotechnology  companies,  most  of  whom  have  considerably  greater  financial,  technical,  and  marketing  resources
than  we  do.  Universities  and  other  research  institutions,  including  the  U.S.  Army  Medical  Research  Institute  of  Infectious  Diseases,  also  compete  in  the
development of treatment technologies, and we face competition from other companies to acquire rights to those technologies.

SGX301 Competition

The FDA has approved several treatments for later stages (IIB-IV) of CTCL and/or in conditions that are unresponsive to prior treatment. Three are targeted
therapies  (Targretin®-caps,  Ontak®  and  Adcetris®),  two  are  histone  deacetylases  inhibitors  (Zolina®  and  Istodax®)  and  the  remaining  two  are  topical
therapies (Valchor® and Targretin®-gel). There are currently no FDA approved therapies for the treatment of front-line, early stage (I-IIA) CTCL; however
certain topical chemotherapies and topical, radiation, photodynamic and other therapies which are approved for indications other than CTCL are prescribed
off-label  for  the  treatment  of  early  stage  CTCL.  These  include  psoralen  combined  with  ultraviolet  A  (UVA)  light  therapy  (“PUVA”);  however,  PUVA
treatments are usually limited to three times per week and 200 times in total due to the potentially carcinogenic side effect. There are other drugs currently in
development that may have the potential to be used in early stage (I-IIA) CTCL – two in phase 2 (vorinostat (Zolina®), cobomarsen), one initiating a Phase 2
study in Poland (TTI-621) and others in phase 1.

SGX94/942 Competition

Because  SGX94  (dusquetide)  uses  a  novel  mechanism  of  action  in  combating  bacterial  infections,  there  are  no  direct  competitors  at  this  time.  Bacterial
infections  are  routinely  treated  with  antibiotics  and  SGX94  treatment  is  anticipated  to  be  utilized  primarily  where  antibiotics  are  insufficient  (e.g.,  due  to
antibiotic resistance) or contra-indicated (e.g., in situations where the development of antibiotic resistance is a significant concern). Many groups are working
on the antibiotic resistance problem and research into the innate immune system is intensifying, making emerging competition likely (from companies such as
Celtaxsys Inc., Innaxon Therapeutics and Innate Pharma SA).

There  is  currently  one  drug  approved  for  the  treatment  of  oral  mucositis  in  hematological  cancer  (palifermin).  There  are  currently  no  approved  drugs  for
treatment of oral mucositis in cancers with solid tumors (e.g., head and neck cancer). There are several drugs in clinical development for oral mucositis –
three in Phase 3 (an epidermal growth factor under development by Daewoong Pharmaceutical Co. Ltd. a protease inhibitor under investigation at a Chinese
hospital, and daily infused GC4419 by Galera Therapeutics Inc.), four in Phase 2 (under development by Innovation Pharmaceuticals, Intrexon Corporation,
Monopar Therapeutics LLC, Moberg Pharma) and various natural products in small and/or open label studies (including sage, turmeric, honey and olive oil).
In addition, there are medical devices approved for the treatment of oral mucositis including MuGard, GelClair, Episil and Caphosol. These devices attempt to
create a protective barrier around the oral ulceration with no biologic activity in treating the underlying disease.

Oral BDP Competition

There are a number of approved treatments for Crohn’s disease and additional compounds are in late-stage development.

Remicade (infliximab) and Humira (adalimumab) are currently approved for the treatment of pediatric Crohn’s disease; however, both carry significant Black
Box warnings in their labeling for increased risk of serious infection and malignancy, and therefore are approved for treatment of moderate to severe patients.
Entocort (enteric-coated budesonide) is currently approved for the treatment of mild to moderate active Crohn’s disease involving the lower GI tract (ileum
and/or  the  ascending  colon)  in  patients  8  years  of  age  and  older  who  weigh  more  than  25  kilograms.  There  is  one  other  marketed  biologic,  Tysabri
(natalizumab), in a Phase 2 study for pediatric Crohn’s.

ThermoVax® Competition

Multiple  groups  and  companies  are  working  to  address  the  unmet  need  of  vaccine  thermostability  using  a  variety  of  technologies.  In  addition,  other
organizations, such as the Bill and Melinda Gates Foundation and PATH, have programs designed to advance technologies to address this need.

Several stabilization technologies currently being developed involve mixing vaccine antigen +/- adjuvant with various proprietary excipients or co-factors that
either serve to stabilize the vaccine or biological product in a liquid or dried (lyophilized) form. Examples of these approaches include the use of various
plant-derived  sugars  and  macromolecules  being  developed  by  companies  such  as  Stabilitech  Ltd.  Variation  Biotechnologies,  Inc.  (“VBI”)  is  developing  a
lipid  system  (resembling  liposomes)  to  stabilize  viral  antigens,  including  virus-like  particles  (“VLPs”),  and  for  potential  application  to  a  conventional
influenza vaccine among others.

Other approaches involve process variations to freeze-dry live virus vaccines. For example, PaxVax, Inc. is seeking to employ a spray drying technology in
concert with enteric coating to achieve formulations for room temperature stability of live virus vaccines using adenovirus vectors. VBI is seeking to utilize
their proprietary stabilization technology for a number of vaccines (as a co-development service, similar to the business model being developed by Stabilitech
Ltd.), whereas PaxVax is applying the technology to their own proprietary vaccine development programs. Stabilitech uses combinations of excipients, which
include glassifying sugars similar to the ThermoVax® technology, and variations in drying cycles during lyophilization, as does the ThermoVax® technology.

Additionally, companies like Pharmathene, Inc., Panacea Biotec Ltd., and Compass Biotech Inc. are developing proprietary vaccines with the application of
some form of stabilization technology.

Vaccines/BioDefense Competition

We face competition in the area of biodefense product development from various public and private companies, universities and governmental agencies, such
as the U.S. Army, some of whom may have their own proprietary technologies which may directly compete with our technologies.

The  U.S.  Army  Medical  Research  Institute  of  Infectious  Diseases,  the  DoD’s  lead  laboratory  for  medical  research  to  counter  biological  threats  is  also
developing a ricin vaccine candidate, RVEc™. RVEc™ has been shown to be fully protective in mice exposed to lethal doses of ricin toxin by the aerosol
route.  Further  studies,  in  both  rabbits  and  nonhuman  primates,  were  conducted  to  evaluate  RVEc™’s  safety  as  well  as  its  immunogenicity,  with  positive
results observed. A monoclonal antibody is also being developed by Mapp Biopharmaceutical Inc. as a ricin therapeutic, with administration 4 hours after
exposure demonstrating efficacy while administration 12 hours after ricin exposure was not protective in animal models.

In the area of radiation-protective antidotes such as OrbeShield®, various companies, such as Cleveland Biolabs, Inc., Pluristem Therapeutics, Inc., Aeolus
Pharmaceuticals,  Inc.  Boulder  Biotechnology,  Inc.,  RxBio,  Inc.,  Avaxia  Biologics,  Inc.,  Exponential  Biotherapies,  Inc.,  Osiris  Therapeutics,  Inc.,
ImmuneRegen  BioSciences,  Inc.,  Neumedicines,  Inc.,  Cellerant  Therapeutics,  Inc.,  Onconova  Therapeutics,  Inc.,  Araim  Pharmaceuticals,  Inc.,  EVA
Pharmaceuticals,  LLC,  Terapio  Corporation,  Cangene  Corporation,  Humanetics  Corporation  and  the  University  of  Arkansas  Medical  Sciences  Center  are
developing biopharmaceutical products that may directly compete with OrbeShield®, even though their approaches to such treatment are different.

RxBio, Avaxia Biologics and the University of Arkansas have programs specifically for GI ARS. RxBio’s Rx100 is a stem cell protectant designed as a single
dose (oral or injection) which has shown promise in nonhuman primate studies. Avaxia is developing an orally delivered anti-TNF antibody as a treatment
agent for exposure to radiation following a nuclear accident, attack or explosion. Pasireotide, a drug in development by Novartis for Cushing’s disease, is
being developed at the University of Arkansas to protect the intestine by reducing pancreatic secretions that exacerbate intestinal inflammation.

Patents and Other Proprietary Rights

Our goal is to obtain, maintain and enforce patent protection for our products, formulations, processes, methods and other proprietary technologies, preserve
our trade secrets, and operate without infringing on the proprietary rights of other parties, both in the U.S. and in other countries. Our policy is to actively
seek to obtain, where appropriate, the broadest intellectual property protection possible for our product candidates, proprietary information and proprietary
technology through a combination of contractual arrangements and patents, both in the U.S. and elsewhere in the world.

We also depend upon the skills, knowledge and experience of our scientific and technical personnel, as well as that of our advisors, consultants and other
contractors, none of which is patentable. To help protect our proprietary knowledge and experience that is not patentable, and for inventions for which patents
may be difficult to enforce, we rely on trade secret protection and confidentiality agreements to protect our interests. To this end, we require all employees,
consultants,  advisors  and  other  contractors  to  enter  into  confidentiality  agreements,  which  prohibit  the  disclosure  of  confidential  information  and,  where
applicable, require disclosure and assignment to us of the ideas, developments, discoveries and inventions important to our business.

In  2014,  we  acquired  a  novel  photodynamic  therapy  that  utilizes  safe  visible  light  for  activation,  which  we  refer  to  as  SGX301.  The  active  ingredient  in
SGX301 is synthetic hypericin, a photosensitizer which is topically applied to skin lesions and then activated by fluorescent light 16 to 24 hours later. As part
of the acquisition, we acquired a license agreement relating to the use of photo-activated hypericin, composition of matter patent for SGX301 (U.S. patent
8,629,302) and additional issued and pending applications, both in the US and abroad. U.S. patent 8,629,302 is expected to expire in September 2030. In
August 2018, we were granted a U.S. patent (No. 10,053,513) titled “Systems and Methods for Producing Synthetic Hypericin”. This newly issued patent,
expected to expire in 2036, broadens the production around synthetic hypericin. Our proprietary formulation of synthetic hypericin also has been granted a
European patent for the treatment of psoriasis, EP 2571507, and complements the method of treatment claims covered by the previously issued US patent
6001882, Photoactivated hypericin and the use thereof.

In addition to issued and pending patents, we also have “Orphan Drug” designations for SGX301 in the U.S. and the EU for CTCL, SGX203 in the U.S. for
pediatric Crohn’s disease, and OrbeShield® in the U.S. for GI ARS, as well as for RiVax® in the U.S and EU. Our Orphan Drug designations provide for
seven years of post-approval marketing exclusivity in the U.S. and ten years exclusivity in Europe. We have pending patent applications for this indication
that, if granted, may extend our anticipated marketing exclusivity beyond the U.S. seven year or E.U. ten year post-approval exclusivity provided by Orphan
Drug legislation.

In 2013, we expanded our patent portfolio to include innate defense regulation through the acquisition of the novel drug technology, known as SGX94. By
binding to the pivotal regulatory protein p62, also known as sequestosome-1, SGX94 regulates the innate immune system to reduce inflammation, eliminate
infection and enhance healing. As part of the acquisition, we acquired all rights, including composition of matter patents for SGX94 as well as other analogs
and crystal structures of SGX94 with its protein target p62, including U.S. patent 8,124,721 and additional pending applications, both in the U.S. and abroad.
SGX94 was developed pursuant to discoveries made by Professors B. Brett Finlay and Robert Hancock of University of British Columbia (“UBC”). U.S.
patent  8,124,721  is  expected  to  expire  in  April  2028.  The  U.S.  Patent  Office  has  granted  the  patent  entitled  “Novel  Peptides  and  Analogs  for  Use  in  the
Treatment  of  Oral  Mucositis”.  The  newly  issued  patent  claims  therapeutic  use  of  dusquetide  and  related  IDR  analogs,  and  adds  to  composition  of  matter
claims for dusquetide and related analogs that have been granted in the U.S. and worldwide. In January 2019, the European Patent Office granted the patent
entitled  “Novel  Peptides  for  Treating  and  Preventing  Immune-Related  Disorders,  Including  Treating  and  Preventing  Infection  by  Modulating  Innate
Immunity”. This newly issued patient claims composition of matter of IDR analogs, expanding patent protection around our lead IDR, dusquetide.

We  have  issued  U.S.  patents  8,263,582  that  cover  the  use  of  oral  BDP  for  treating  inflammatory  disorders  of  the  gastrointestinal  tract,  which  patent  is
expected  to  expire  in  March  2022.  We  also  have  European  patent  EP  1392321  claiming  the  use  of  topically  active  corticosteroids  in  orally  administered
dosage forms that act concurrently to treat inflammation in the upper and lower gastrointestinal tract, as well as European patent EP 2242477 claiming the use
of orally ingested BDP for treatment of interstitial lung disease. European patents EP 1392321 and EP 2242477 are expected to expire in March 2022 and
January 2029.

The subject of U.S. patent application number 12/633,631 filed December 8, 2009 and continued into patent application 15/495,798 filed April 24, 2017 and
corresponding European patent application number 09836727.9, which was granted as patent 2373160 in October 2017 and pursued in multiple European
countries,  is  the  use  of  topically  active  BDP  in  radiation  and  chemotherapeutics  injury.  Additionally,  we  have  numerous  patent  filings  currently  issued  or
pending in foreign jurisdictions covering this subject matter, including Australia, Canada, China, Hong Kong, Israel, Japan, South Korea and New Zealand.

ThermoVax® is the subject of U.S. patent 8,444,991 issued on May 21, 2013 titled “Method of Preparing an Immunologically-Active Adjuvant-Bound Dried
Vaccine Composition” and also U.S. patent application number 13/474,661 filed May 17, 2012 titled “Thermostable Vaccine Compositions and Methods of
Preparing Same.” The patent application and the corresponding foreign filings for both patents are pending and licensed to us by the UC and they address the
use  of  adjuvants  in  conjunction  with  vaccines  that  are  formulated  to  resist  thermal  inactivation.  The  license  agreement  covers  thermostable  vaccines  for
biodefense as well as other potential vaccine indications. U.S. patent 8,444,991 is expected to expire in February 2030.

RiVax® is the subject of three issued U.S. patent numbers 6,566,500, 6,960,652, and 7,829,668, all titled “Compositions and methods for modifying toxic
effects of proteinaceous compounds.” This patent family includes composition of matter claims for the modified ricin toxin A chain which is the immunogen
contained in RiVax®, and issued in 2003, 2005 and 2010 respectively. The initial filing date of these patents is March 2000 and they are expected to expire in
March  2020.  The  issued  patents  contain  claims  that  describe  alteration  of  sequences  within  the  ricin  A  chain  that  affect  vascular  leak,  one  of  the  deadly
toxicities caused by ricin toxin. Another U.S. patent number 7,175,848 titled “Ricin A chain mutants lacking enzymatic activity as vaccines to protect against
aerosolized ricin,” was filed in October of 2000 and is expected to expire in September 2020.

SGX301 License Agreement

In September 2014, we acquired a worldwide exclusive license agreement with New York University and Yeda Research and Development Company Ltd. for
the  rights  to  a  novel  photodynamic  therapy  that  utilizes  safe  visible  light  for  activation,  which  we  refer  to  as  SGX301.  To  maintain  this  license  we  are
obligated to pay $25,000 in annual license fees. In addition, we will pay the licensors: (a) a royalty amount equal to 3% of all net sales of SGX301 made
directly by us and/or any affiliates; (b) a royalty amount equal to 2.5% of all net sales of SGX301 made by our sublicensees, subject to stated maximums and
(c)  20%  of  all  payments,  not  based  on  net  sales,  received  by  us  from  our  sublicensees.  This  license  may  be  terminated  by  either  party  upon  notice  of  a
material breach by the other party that is not cured within the applicable cure period. The exclusive license includes rights to several issued U.S. patents,
including U.S. patent numbers 6,867,235 and 7,122,518, among other domestic and foreign patent applications. U.S. Patent numbers 6,867,235 and 7,122,518
are expected to expire in January 2020 and November 2023, respectively.

We  acquired  the  license  agreement  for  SGX301  and  related  intangible  assets,  including  U.S.  patent  8,629,302,  properties  and  rights  pursuant  to  an  asset
purchase  agreement  with  Hy  Biopharma  Inc.  (“Hy  Biopharma”).  As  consideration  for  the  assets  acquired,  we  paid  $275,000  in  cash  and  issued  184,912
shares  of  common  stock  with  a  market  value  of  $3,750,000.  Provided  all  future  success-orientated  milestones  are  attained,  we  will  be  required  to  make
payments of up to $10.0 million, if and when achieved, payable in our common stock.

SGX94 License Agreements

On December 18, 2012, we announced the acquisition of a first in class drug technology, known as SGX94 (dusquetide), representing a novel approach to
modulation of the innate immune system. SGX94 is an IDR that regulates the innate immune system to reduce inflammation, eliminate infection and enhance
tissue healing by binding to the pivotal regulatory protein p62, also known as sequestosome-1. As part of the acquisition, we acquired all rights, including
composition of matter patents, preclinical and Phase 1 clinical study datasets for SGX94. We also assumed a license agreement with UBC to advance the
research  and  development  of  the  SGX94  technology.  The  license  agreement  with  UBC  provides  us  with  exclusive  worldwide  rights  to  manufacture,
distribute, market sell and/or license or sublicense products derived or developed from this technology. Under the license agreement we are obligated to pay
UBC (i) an annual license maintenance fee of CAN $1,000, and (ii) milestone payments which could reach up to CAN $1.2 million. This license agreement
(a) will automatically terminate if we file, or become subject to an involuntary filing, for bankruptcy, and (b) may be terminated by UBC in the event of,
among other things, our insolvency, dissolution, grant of a security interest in the technology licensed to us pursuant to the license agreement, or material
breach of or failure to perform material obligations under the license agreement or other research agreements between us and UBC.

Oral BDP License Agreement

On November 24, 1998, the Company, known at the time as Enteron Pharmaceuticals, Inc. (“Enteron”) and George B. McDonald (“Dr. McDonald”) entered
into  an  exclusive  license  agreement  for  the  rights  to  intellectual  property,  including  know-how,  relating  to  oral  BDP.  We  have  an  exclusive  license  to
commercially exploit the covered products worldwide, subject to Dr. McDonald’s right to make and use the technology for research purposes and the U.S.
Government’s right to use the technology for government purposes. Pursuant to the license agreement, as amended, we are is required to (i) reimburse Dr.
McDonald for certain out-of-pocket expenses incurred by Dr. McDonald in connection with the patent applications and issued patents, (ii) pay Dr. McDonald
$300,000  upon  approval  by  the  FDA  of  our  first  NDA  incorporating  oral  BDP;  (iii)  pay  Dr.  McDonald  royalty  payments  equal  to  3%  of  net  sales  of  the
covered products and (iv) pay Dr. McDonald $400,000 in cash upon an approval of oral BDP by the European Medicines Agency.

Additionally, in the event that sublicenses our rights under the license agreement, we will be required to pay Dr. McDonald 10% of any sublicense fees and
royalty payments paid by the sublicense to us.

The  term  of  the  license  agreement  expires  upon  the  expiration  of  the  licensed  patent  applications  or  patents.  Dr.  McDonald  has  the  right  to  terminate  the
license  agreement  in  its  entirety  or  to  terminate  exclusivity  under  the  agreement  if  we  or  its  sublicenses  have  not  commercialized  or  are  not  actively
attempting to commercialize a covered product.

Additionally,  the  agreement  terminates:  (i)  automatically  upon  us  becoming  insolvent;  (ii)  upon  30  days’  notice,  if  we  breach  any  obligation  under  the
agreement without curing such breach during the notice period; and (iii) upon 90 days’ notice by us. After any termination, we will have the right to sell our
inventory for a period not to exceed three months following the date of termination, subject to the payment of the amounts owed under the agreement.

ThermoVax® License Agreement

On December 21, 2010, we executed a worldwide exclusive license agreement with the UC for ThermoVax®, which is the subject of U.S. patent number
8,444,991 issued on May 21, 2013 titled “Method of Preparing an Immunologically-Active Adjuvant-Bound Dried Vaccine Composition.” This patent and its
corresponding foreign filings are licensed to us by the UC and they address the use of adjuvants in conjunction with vaccines that are formulated to resist
thermal inactivation. U.S. Patent 8,444,991 is expected to expire in December 2031. The license agreement also covers thermostable vaccines for biodefense
as well as other potential vaccine indications. In addition, we, in conjunction with UC, filed domestic and foreign patent applications claiming priority back to
a  provisional  application  filed  on  May  17,  2011  titled:  “Thermostable  Vaccine  Compositions  and  Methods  of  Preparing  Same.”  In  April  2018,  the  UC
delivered  a  notice  of  termination  of  our  license  agreement  based  upon  our  failure  to  achieve  one  of  the  development  milestones:  initiation  of  the  Phase  1
clinical trial of the heat stabilization technology by March 31, 2018. After negotiating with the UC, we and the UC agreed to extend the termination date to
October 31, 2018 in order to allow us time to agree upon a potential agreement that would allow us to keep the rights to, and to continue to develop, the heat
stabilization technology or a product candidate containing the heat stabilization technology in our field of use.

On  October  31,  2018,  in  a  series  of  related  transactions,  (a)  we  and  the  UC  agreed  to  terminate  the  original  license  agreement,  (b)  the  UC  and  VitriVax
executed a worldwide exclusive license agreement for the heat stabilization technology for all fields of use, and (c) we and VitriVax executed a worldwide
exclusive sublicense agreement for the heat stabilization technology for use in the fields of ricin and Ebola vaccines. We paid a $100,000 sublicense fee on
the effective date of the sublicense agreement. To maintain the sublicense we are obliged to pay a minimum annual royalty of $20,000 until first commercial
sale of a sublicensed product, upon which point, we will be required to pay an earned royalty of 2% of net sales subject to a minimum royalty of $50,000 each
year. We are also required to pay royalties on any sub-sublicense income based on a declining percentage of all sub-sublicense income calculated within the
contractual  period  until  reaching  a  minimum  of  15%  after  two  years.  In  addition,  we  are  required  to  pay  VitriVax  milestone  fees  of:  (a)  $50,000  upon
initiation  of  a  Phase  II  clinical  trial  of  the  sublicensed  product,  (b)  $200,000  upon  regulatory  approval  of  a  sublicensed  product,  and  (c)  $1  million  upon
achieving $10 million in aggregate net sales of a sublicensed product in the U.S. or equivalent. To date none of these milestones have been met.

RiVax® License Agreement

In June 2003, we executed a worldwide exclusive option to license patent applications with UTSW for the nasal, pulmonary and oral uses of a non-toxic ricin
vaccine. In June 2004, we entered into a license agreement with UTSW for the injectable rights to the ricin vaccine and, in October 2004, we negotiated the
remaining oral rights to the ricin vaccine. To maintain this license we are obligated to pay $50,000 in annual license fees. Through this license, we have rights
to the issued patent number 7,175,848 titled “Ricin A chain mutants lacking enzymatic activity as vaccines to protect against aerosolized ricin.” This patent
includes methods of use and composition claims for RiVax®.

Research and Development Expenditures

We  spent  approximately  $6.8  million  and  $5.5  million  in  the  years  ended  December  31,  2018  and  2017,  respectively,  on  research  and  development.  The
amounts we spent on research and development per product during the years ended December 31, 2018, and 2017 are set forth in “Management’s Discussion
and Analysis of Financial Condition and Results of Operations” in this Annual Report on Form 10-K.

Employees

As of December 31, 2018, we had 14 full-time employees, 6 of whom are MDs/PhDs.

Item 1A. Risk factors

An investment in our securities involves a high degree of risk. You should carefully consider the following information about these risks, together with the
other  information  about  these  risks  contained  in  this  Annual  Report,  as  well  as  the  other  information  contained  in  this  Annual  Report  generally,  before
deciding to buy our securities. Any of the risks we describe below could adversely affect our business, financial condition, operating results or prospects. The
market prices for our securities could decline if one or more of these risks and uncertainties develop into actual events and you could lose all or part of your
investment. Additional risks and uncertainties that we do not yet know of, or that we currently think are immaterial, may also impair our business operations.
You should also refer to the other information contained in this Annual Report, including our financial statements and the related notes.

Risks Related to our Business

We  have  had  significant  losses  and  anticipate  future  losses;  if  additional  funding  cannot  be  obtained,  we  may  reduce  or  discontinue  our  product
development and commercialization efforts.

We have experienced significant losses since inception and, at December 31, 2018, had an accumulated deficit of approximately $166 million. We expect to
incur additional operating losses in the future and expect our cumulative losses to increase. As of December 31, 2018, we had approximately $9.0 million in
cash and cash equivalents available. Based on our projected budgetary needs, funding from existing contracts and grants over the next two years and sales
pursuant to our At the Market Issuance Sales Agreement (“FBR Sales Agreement”) with B. Riley FBR, Inc. (“FBR”), we expect to be able to maintain the
current level of our operations through at least March 31, 2020.

In September 2014, we entered into a contract with the NIH for the development of RiVax® to protect against exposure to ricin toxin that would provide up to
$24.7  million  of  funding  in  the  aggregate  over  six  years  if  options  to  extend  the  contract  are  exercised  by  the  NIH.  In  September  2013,  we  entered  into
contracts with NIAID and BARDA for the development of OrbeShield®  that  would  provide  up  to  $32.7  million  of  funding  in  the  aggregate  if  options  to
extend the contracts are exercised by BARDA and the NIH. We have received approximately $18 million in combined BARDA and NIH contract funding for
the development of OrbeShield®. We have completed the contract with NIAID and the BARDA contract base period, with BARDA electing not to extend the
contract. In addition, in 2017, we were awarded two separate grants from the NIH of approximately $1.5 million each to support our pivotal Phase 3 trials of
SGX301  for  the  treatment  of  CTCL  and  SGX942  for  the  treatment  of  oral  mucositis  in  head  and  neck  cancer.  Our  biodefense  grants  have  an  overhead
component  that  allows  us  an  agency-approved  percentage  over  our  incurred  costs.  We  estimate  that  the  overhead  component  associated  with  our  existing
contracts  and  grants  will  fund  some  fixed  costs  for  direct  employees  working  on  these  contracts  and  grants  as  well  as  other  administrative  costs.  As  of
December  31,  2018,  we  have  approximately  $14.6  million  in  awarded  contract  and  grant  funding,  assuming  the  NIAID  option  is  exercised  for  the
development of RiVax®.

Our product candidates are positioned for or are currently in clinical trials, and we have not yet generated any significant revenues from sales or licensing of
these  product  candidates.  From  inception  through  December  31,  2018,  we  have  expended  approximately  $83.0  million  developing  our  current  product
candidates  for  pre-clinical  research  and  development  and  clinical  trials,  and  we  currently  expect  to  spend  approximately  $9.3  million  for  the  year  ending
December  31,  2019  in  connection  with  the  development  of  our  therapeutic  and  vaccine  products,  licenses,  employment  agreements,  and  consulting
agreements, of which approximately $3.3 million is expected to be reimbursed through our existing government contracts and grants.

25

 
 
 
 
 
 
 
 
 
We have no control over the resources and funding NIH, BARDA and NIAID may devote to our programs, which may be subject to periodic renewal and
which generally may be terminated by the government at any time for convenience. Any significant reductions in the funding of U.S. government agencies or
in  the  funding  areas  targeted  by  our  business  could  materially  and  adversely  affect  our  biodefense  program  and  our  results  of  operations  and  financial
condition.  If  we  fail  to  satisfy  our  obligations  under  the  government  contracts,  the  applicable  Federal  Acquisition  Regulations  allow  the  government  to
terminate the agreement in whole or in part, and we may be required to perform corrective actions, including but not limited to delivering to the government
any incomplete work. If NIH, BARDA or NIAID do not exercise future funding options under the contracts or grants, terminate the funding or fail to perform
their responsibilities under the agreements or grants, it could materially impact our biodefense program and our financial results.

Unless  and  until  we  are  able  to  generate  sales  or  licensing  revenue  from  one  of  our  product  candidates,  we  will  require  additional  funding  to  meet  these
commitments, sustain our research and development efforts, provide for future clinical trials, and continue our operations. There can be no assurance we can
raise such funds. If additional funds are raised through the issuance of equity securities, stockholders may experience dilution of their ownership interests, and
the newly issued securities may have rights superior to those of the common stock. If additional funds are raised by the issuance of debt, we may be subject to
limitations on our operations. If we cannot raise such additional funds, we may have to delay or stop some or all of our drug development programs.

If we are unable to develop our product candidates, our ability to generate revenues and viability as a company will be significantly impaired.

In  order  to  generate  revenues  and  profits,  our  organization  must,  along  with  corporate  partners  and  collaborators,  positively  research,  develop  and
commercialize our technologies or product candidates. Our current product candidates are in various stages of clinical and pre-clinical development and will
require significant further funding, research, development, pre-clinical and/or clinical testing, regulatory approval and commercialization, and are subject to
the risks of failure inherent in the development of products based on innovative or novel technologies. Specifically, each of the following is possible with
respect to any of our product candidates:

● we may not be able to maintain our current research and development schedules;

● we may be unable to secure procurement contracts on beneficial economic terms or at all from the U.S. government or others for our biodefense

products;

● we may encounter problems in clinical trials; or

● the technology or product may be found to be ineffective or unsafe, or may fail to obtain marketing approval.

If any of the risks set forth above occur, or if we are unable to obtain the necessary regulatory approvals as discussed below, we may be unable to develop our
technologies and product candidates and our business will be seriously harmed. Furthermore, for reasons including those set forth below, we may be unable to
commercialize or receive royalties from the sale of any other technology we develop, even if it is shown to be effective, if:

● it is not economical or the market for the product does not develop or diminishes;

● we are not able to enter into arrangements or collaborations to manufacture and/or market the product;

● the product is not eligible for third-party reimbursement from government or private insurers;

● others hold proprietary rights that preclude us from commercializing the product;

● we are not able to manufacture the product reliably;

● others have brought to market similar or superior products; or

● the product has undesirable or unintended side effects that prevent or limit its commercial use.

26

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We expect a number of factors to cause our operating results to fluctuate on a quarterly and annual basis, which may make it difficult to predict our
future performance.

We are a late-stage biopharmaceutical company. Our operations to date have been primarily limited to developing our technology and undertaking pre-clinical
studies and clinical trials of our product candidates in our two active business segments, BioTherapeutics and Vaccines/BioDefense. We have not yet obtained
regulatory approvals for any of our product candidates. Consequently, any predictions made about our future success or viability may not be as accurate as
they could be if we had commercialized products. Our financial condition has varied significantly in the past and will continue to fluctuate from quarter-to-
quarter  or  year-to-year  due  to  a  variety  of  factors,  many  of  which  are  beyond  our  control.  Factors  relating  to  our  business  that  may  contribute  to  these
fluctuations include other factors described elsewhere in this Annual Report and also include:

● our ability to obtain additional funding to develop our product candidates;

● delays in the commencement, enrollment and timing of clinical trials;

● the success of our product candidates through all phases of clinical development;

● any delays in regulatory review and approval of product candidates in clinical development;

● our ability to obtain and maintain regulatory approval for our product candidates in the United States and foreign jurisdictions;

● potential side effects of our product candidates that could delay or prevent commercialization, limit the indications for any approved drug, require

the establishment of risk evaluation and mitigation strategies, or cause an approved drug to be taken off the market;

● our dependence on third-party contract manufacturing organizations to supply or manufacture our products;

● our dependence on contract research organizations to conduct our clinical trials;

● our ability to establish or maintain collaborations, licensing or other arrangements;

● market acceptance of our product candidates;

● our ability  to  establish  and  maintain  an  effective  sales  and  marketing  infrastructure,  either  through  the  creation  of  a  commercial  infrastructure  or

through strategic collaborations;

● competition from existing products or new products that may emerge;

● the ability of patients or healthcare providers to obtain coverage of or sufficient reimbursement for our products;

● our ability to discover and develop additional product candidates;

● our ability and our licensors’ abilities to successfully obtain, maintain, defend and enforce intellectual property rights important to our business;

● our ability to attract and retain key personnel to manage our business effectively;

● our ability to build our finance infrastructure and improve our accounting systems and controls;

● potential product liability claims;

27

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● potential liabilities associated with hazardous materials; and

● our ability to obtain and maintain adequate insurance policies.

Accordingly, the results of any quarterly or annual periods should not be relied upon as indications of future operating performance.

We have no approved products on the market and therefore do not expect to generate any revenues from product sales in the foreseeable future, if at all.

To date, we have no approved product on the market and have not generated any significant product revenues. We have funded our operations primarily from
sales of our securities and from government contracts and grants. We have not received, and do not expect to receive for at least the next several years, if at
all, any revenues from the commercialization of our product candidates. To obtain revenues from sales of our product candidates, we must succeed, either
alone or with third parties, in developing, obtaining regulatory approval for, manufacturing and marketing drugs with commercial potential or successfully
obtain government procurement or stockpiling agreements. We may never succeed in these activities, and we may not generate sufficient revenues to continue
our business operations or achieve profitability.

Our business is subject to extensive governmental regulation, which can be costly, time consuming and subjects us to unanticipated delays.

Our business is subject to very stringent federal, foreign, state and local government laws and regulations, including the Federal Food, Drug and Cosmetic
Act, the Environmental Protection Act, the Occupational Safety and Health Act, and state and local counterparts to these acts. These laws and regulations may
be amended, additional laws and regulations may be enacted, and the policies of the FDA and other regulatory agencies may change.

The regulatory process applicable to our products requires pre-clinical and clinical testing of any product to establish its safety and efficacy. This testing can
take many years, is uncertain as to outcome, and requires the expenditure of substantial capital and other resources. We estimate that the clinical trials of our
product candidates that we have planned will take at least several years to complete. Furthermore, failure can occur at any stage of the trials, and we could
encounter problems that cause us to abandon or repeat clinical trials. Favorable results in early studies or trials, if any, may not be repeated in later studies or
trials.  Even  if  our  clinical  trials  are  initiated  and  completed  as  planned,  we  cannot  be  certain  that  the  results  will  support  our  product  candidate  claims.
Success in preclinical testing, Phase 1 and Phase 2 clinical trials does not ensure that later Phase 2 or Phase 3 clinical trials will be successful. In addition, we,
the FDA or other regulatory authorities may suspend clinical trials at any time if it appears that we are exposing participants to unacceptable health risks or
the FDA or other regulatory authorities find deficiencies in our submissions or conduct of our trials.

We  may  not  be  able  to  obtain,  or  we  may  experience  difficulties  and  delays  in  obtaining,  necessary  domestic  and  foreign  governmental  clearances  and
approvals to market a product. Also, even if regulatory approval of a product is granted, that approval may entail limitations on the indicated uses for which
the product may be marketed.

Following any regulatory approval, a marketed product and its manufacturer are subject to continual regulatory review. Later discovery of problems with a
product  or  manufacturer  may  result  in  restrictions  on  such  product  or  manufacturer.  These  restrictions  may  include  product  recalls  and  suspension  or
withdrawal of the marketing approval for the product. Furthermore, the advertising, promotion and export, among other things, of a product are subject to
extensive regulation by governmental authorities in the U.S. and other countries. If we fail to comply with applicable regulatory requirements, we may be
subject to fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and/or criminal prosecution.

28

 
 
 
 
 
 
 
 
 
 
 
 
There may be unforeseen challenges in developing our biodefense products.

For development of biodefense vaccines and therapeutics, the FDA has instituted policies that are expected to result in accelerated approval. This includes
approval for commercial use using the results of animal efficacy trials, rather than efficacy trials in humans, referred to as the Animal Rule. However, we will
still have to establish that the vaccines we are developing are safe in humans at doses that are correlated with the beneficial effect in animals. Such clinical
trials  will  also  have  to  be  completed  in  distinct  populations  that  are  subject  to  the  countermeasures;  for  instance,  the  very  young  and  the  very  old,  and  in
pregnant women, if the countermeasure is to be licensed for civilian use. Other agencies will have an influence over the risk benefit scenarios for deploying
the countermeasures and in establishing the number of doses utilized in the Strategic National Stockpile. We may not be able to sufficiently demonstrate the
animal correlation to the satisfaction of the FDA, as these correlates are difficult to establish and are often unclear. Invocation of the Animal Rule may raise
issues of confidence in the model systems even if the models have been validated. For many of the biological threats, the animal models are not available and
we may have to develop the animal models, a time-consuming research effort. There are few historical precedents, or recent precedents, for the development
of new countermeasures for bioterrorism agents. Despite the Animal Rule, the FDA may require large clinical trials to establish safety and immunogenicity
before  licensure  and  it  may  require  safety  and  immunogenicity  trials  in  additional  populations.  Approval  of  biodefense  products  may  be  subject  to  post-
marketing studies, and could be restricted in use in only certain populations. The government’s biodefense priorities can change, which could adversely affect
the commercial opportunity for the products we are developing. Further, other countries have not, at this time, established criteria for review and approval of
these types of products outside their normal review process, i.e., there is no Animal Rule equivalent, and consequently there can be no assurance that we will
be able to make a submission for marketing approval in foreign countries based on such animal data.

Additionally,  few  facilities  in  the  United  States  and  internationally  have  the  capability  to  test  animals  with  ricin,  or  otherwise  assist  us  in  qualifying  the
requisite animal models. We have to compete with other biodefense companies for access to this limited pool of highly specialized resources. We therefore
may not be able to secure contracts to conduct the testing in a predictable timeframe or at all.

We are dependent on government funding, which is inherently uncertain, for the success of our biodefense operations.

We are subject to risks specifically associated with operating in the biodefense industry, which is a new and unproven business area. We do not anticipate that
a significant commercial market will develop for our biodefense products. Because we anticipate that the principal potential purchasers of these products, as
well as potential sources of research and development funds, will be the U.S. government and governmental agencies, the success of our biodefense division
will  be  dependent  in  large  part  upon  government  spending  decisions.  The  funding  of  government  programs  is  dependent  on  budgetary  limitations,
congressional appropriations and administrative allotment of funds, all of which are inherently uncertain and may be affected by changes in U.S. government
policies resulting from various political and military developments. Our receipt of government funding is also dependent on our ability to adhere to the terms
and provisions of the original grant and contract documents and other regulations. We can provide no assurance that we will receive or continue to receive
funding for grants and contracts we have been awarded. The loss of government funds could have a material adverse effect on our ability to progress our
biodefense business.

If  the  parties  we  depend  on  for  supplying  our  drug  substance  raw  materials  and  certain  manufacturing-related  services  do  not  timely  supply  these
products and services, it may delay or impair our ability to develop, manufacture and market our products. We do not have or anticipate having internal
manufacturing capabilities.

We  rely  on  suppliers  for  our  drug  substance  raw  materials  and  third  parties  for  certain  manufacturing-related  services  to  produce  material  that  meets
appropriate  content,  quality  and  stability  standards,  which  material  will  be  used  in  clinical  trials  of  our  products  and,  after  approval,  for  commercial
distribution. To succeed, clinical trials require adequate supplies of drug substance and drug product, which may be difficult or uneconomical to procure or
manufacture. We and our suppliers and vendors may not be able to (i) produce our drug substance or drug product to appropriate standards for use in clinical
studies, (ii) perform under any definitive manufacturing, supply or service agreements with us or (iii) remain in business for a sufficient time to be able to
develop, produce, secure regulatory approval of and market our product candidates. If we do not maintain important manufacturing and service relationships,
we may fail to find a replacement supplier or required vendor or develop our own manufacturing capabilities which could delay or impair our ability to obtain
regulatory  approval  for  our  products  and  substantially  increase  our  costs  or  deplete  profit  margins,  if  any.  If  we  do  find  replacement  manufacturers  and
vendors, we may not be able to enter into agreements with them on terms and conditions favorable to us and, there could be a substantial delay before a new
facility could be qualified and registered with the FDA and foreign regulatory authorities.

29

 
 
 
 
 
 
 
 
 
We  rely  on  third  parties  for  pre-clinical  and  clinical  trials  of  our  product  candidates  and,  in  some  cases,  to  maintain  regulatory  files  for  our  product
candidates. If we are not able to maintain or secure agreements with such third parties on acceptable terms, if these third parties do not perform their
services as required, or if these third parties fail to timely transfer any regulatory information held by them to us, we may not be able to obtain regulatory
approval for, or commercialize, our product candidates.

We rely on academic institutions, hospitals, clinics and other third-party collaborators for preclinical and clinical trials of our product candidates. Although we
monitor, support, and/or oversee our pre-clinical and clinical trials, because we do not conduct these trials ourselves, we have less control over the timing and
cost of these studies and the ability to recruit trial subjects than if we conducted these trials wholly by ourselves. If we are unable to maintain or enter into
agreements with these third parties on acceptable terms, or if any such engagement is terminated, we may be unable to enroll patients on a timely basis or
otherwise conduct our trials in the manner we anticipate. In addition, there is no guarantee that these third parties will devote adequate time and resources to
our studies or perform as required by a contract or in accordance with regulatory requirements, including maintenance of clinical trial information regarding
our product candidates. If these third parties fail to meet expected deadlines, fail to timely transfer to us any regulatory information, fail to adhere to protocols
or fail to act in accordance with regulatory requirements or our agreements with them, or if they otherwise perform in a substandard manner or in a way that
compromises  the  quality  or  accuracy  of  their  activities  or  the  data  they  obtain,  then  preclinical  and/or  clinical  trials  of  our  product  candidates  may  be
extended, delayed or terminated, or our data may be rejected by the FDA or regulatory agencies.

The  manufacturing  of  our  products  is  a  highly  exacting  process,  and  if  we  or  one  of  our  materials  suppliers  encounter  problems  manufacturing  our
products, our business could suffer.

The  FDA  and  foreign  regulators  require  manufacturers  to  register  manufacturing  facilities.  The  FDA  and  foreign  regulators  also  inspect  these  facilities  to
confirm compliance with current Good Manufacturing Practice (“cGMP”) or similar requirements that the FDA or foreign regulators establish. We, or our
materials  suppliers,  may  face  manufacturing  or  quality  control  problems  causing  product  production  and  shipment  delays  or  a  situation  where  we  or  the
supplier may not be able to maintain compliance with the FDA’s cGMP requirements, or those of foreign regulators, necessary to continue manufacturing our
drug substance. Any failure to comply with cGMP requirements or other FDA or foreign regulatory requirements could adversely affect our clinical research
activities and our ability to market and develop our products.

We  may  use  our  financial  and  human  resources  to  pursue  a  particular  research  program  or  product  candidate  and  fail  to  capitalize  on  programs  or
product candidates that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and human resources, we are currently focusing on the regulatory approval of certain product candidates. As a result, we
may forego or delay pursuit of opportunities with other product candidates or for other indications that later prove to have greater commercial potential. Our
resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on existing
and  future  product  candidates  for  specific  indications  may  not  yield  any  commercially  viable  products.  If  we  do  not  accurately  evaluate  the  commercial
potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through strategic alliance, licensing
or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such
product candidate, or we may allocate internal resources to a product candidate in an area in which it would have been more advantageous to enter into a
partnering arrangement.

30

 
 
 
 
 
 
 
 
Even if approved, our products will be subject to extensive post-approval regulation.

Once a product is approved, numerous post-approval requirements apply. Among other things, the holder of an approved New Drug Application (“NDA”) is
subject  to  periodic  and  other  FDA  monitoring  and  reporting  obligations,  including  obligations  to  monitor  and  report  adverse  events  and  instances  of  the
failure of a product to meet the specifications in the NDA. Application holders must submit new or supplemental applications and obtain FDA approval for
certain changes to the approved product, product labeling, or manufacturing process. Application holders must also submit advertising and other promotional
material to the FDA and report on ongoing clinical trials.

Depending on the circumstances, failure to meet these post-approval requirements can result in criminal prosecution, fines, injunctions, recall or seizure of
products,  total  or  partial  suspension  of  production,  denial  or  withdrawal  of  pre-marketing  product  approvals,  or  refusal  to  allow  us  to  enter  into  supply
contracts,  including  government  contracts.  In  addition,  even  if  we  comply  with  FDA  and  other  requirements,  new  information  regarding  the  safety  or
effectiveness of a product could lead the FDA to modify or withdraw product approval.

 Even if we obtain regulatory approval to market our product candidates, our product candidates may not be accepted by the market.

Even if the FDA approves one or more of our product candidates, physicians and patients may not accept it or use it. Even if physicians and patients would
like to use our products, our products may not gain market acceptance among healthcare payors such as managed care formularies, insurance companies or
government programs such as Medicare or Medicaid. Acceptance and use of our products will depend upon a number of factors including: perceptions by
members of the health care community, including physicians, about the safety and effectiveness of our drug product; cost-effectiveness of our product relative
to  competing  products;  availability  of  reimbursement  for  our  product  from  government  or  other  healthcare  payers;  and  effectiveness  of  marketing  and
distribution efforts by us and our licensees and distributors, if any.

The degree of market acceptance of any product that we develop will depend on a number of factors, including:

● cost-effectiveness;

● the  safety  and  effectiveness  of  our  products,  including  any  significant  potential  side  effects,  as  compared  to  alternative  products  or  treatment

methods;

● the timing of market entry as compared to competitive products;

● the rate of adoption of our products by doctors and nurses;

● product labeling or product insert required by the FDA for each of our products;

● reimbursement policies of government and third-party payors;

● effectiveness of our sales, marketing and distribution capabilities and the effectiveness of such capabilities of our collaborative partners, if any; and

● unfavorable publicity concerning our products or any similar products.

Our product candidates, if successfully developed, will compete with a number of products manufactured and marketed by major pharmaceutical companies,
biotechnology companies and manufacturers of generic drugs. Our products may also compete with new products currently under development by others.
Physicians, patients, third-party payors and the medical community may not accept and utilize any of our product candidates. If our products do not achieve
market acceptance, we will not be able to generate significant revenues or become profitable.

Because we expect sales of our current product candidates, if approved, to generate substantially all of our product revenues for the foreseeable future, the
failure of these products to find market acceptance would harm our business and could require us to seek additional financing.

31

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We do not have extensive sales and marketing experience and our lack of experience may restrict our success in commercializing some of our product
candidates.

We do not have extensive experience in marketing or selling pharmaceutical products whether in the U.S. or internationally. To obtain the expertise necessary
to successfully market and sell any of our products, the development of our own commercial infrastructure and/or collaborative commercial arrangements and
partnerships will be required. Our ability to make that investment and also execute our current operating plan is dependent on numerous factors, including, the
performance of third party collaborators with whom we may contract.

Our products, if approved, may not be commercially viable due to change in health care practice and third party reimbursement limitations.

Initiatives  to  reduce  the  federal  deficit  and  to  change  health  care  delivery  are  increasing  cost-containment  efforts.  We  anticipate  that  Congress,  state
legislatures and the private sector will continue to review and assess alternative benefits, controls on health care spending through limitations on the growth of
private health insurance premiums and Medicare and Medicaid spending, price controls on pharmaceuticals, and other fundamental changes to the health care
delivery  system.  Any  changes  of  this  type  could  negatively  impact  the  commercial  viability  of  our  products,  if  approved.  Our  ability  to  successfully
commercialize our product candidates, if they are approved, will depend in part on the extent to which appropriate reimbursement codes and authorized cost
reimbursement levels of these products and related treatment are obtained from governmental authorities, private health insurers and other organizations, such
as health maintenance organizations. In the absence of national Medicare coverage determination, local contractors that administer the Medicare program may
make  their  own  coverage  decisions.  Any  of  our  product  candidates,  if  approved  and  when  commercially  available,  may  not  be  included  within  the  then
current  Medicare  coverage  determination  or  the  coverage  determination  of  state  Medicaid  programs,  private  insurance  companies  or  other  health  care
providers. In addition, third-party payers are increasingly challenging the necessity and prices charged for medical products, treatments and services.

Our product candidates may cause serious adverse events or undesirable side effects which may delay or prevent marketing approval, or, if approval is
received, require them to be taken off the market, require them to include safety warnings or otherwise limit their sales.

Serious adverse events or undesirable side effects from any of our product candidates could arise either during clinical development or, if approved, after the
approved product has been marketed. The results of future clinical trials may show that our product candidates cause serious adverse events or undesirable
side  effects,  which  could  interrupt,  delay  or  halt  clinical  trials,  resulting  in  delay  of,  or  failure  to  obtain,  marketing  approval  from  the  FDA  and  other
regulatory authorities.

If any of our product candidates cause serious adverse events or undesirable side effects:

● regulatory authorities may impose a clinical hold which could result in substantial delays and adversely impact our ability to continue development

of the product;

● regulatory  authorities  may  require  the  addition  of  labeling  statements,  specific  warnings,  a  contraindication  or  field  alerts  to  physicians  and

pharmacies;

● we may be required to change the way the product is administered, conduct additional clinical trials or change the labeling of the product;

● we may be required to implement a risk minimization action plan, which could result in substantial cost increases and have a negative impact on our

ability to commercialize the product;

● we may be required to limit the patients who can receive the product;

● we may be subject to limitations on how we promote the product;

32

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● sales of the product may decrease significantly;

● regulatory authorities may require us to take our approved product off the market;

● we may be subject to litigation or product liability claims; and

● our reputation may suffer.

Any  of  these  events  could  prevent  us  from  achieving  or  maintaining  market  acceptance  of  the  affected  product  or  could  substantially  increase
commercialization costs and expenses, which in turn could delay or prevent us from generating significant revenues from the sale of our products.

If we fail to obtain or maintain orphan drug exclusivity for our product candidates, our competitors may sell products to treat the same conditions and
our revenue will be reduced.

Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is intended to treat a rare disease or condition, defined as a patient
population  of  fewer  than  200,000  in  the  United  States,  or  a  patient  population  greater  than  200,000  in  the  United  States  where  there  is  no  reasonable
expectation that the cost of developing the drug will be recovered from sales in the United States. In the European Union, the European Medicines Agency’s
Committee  for  Orphan  Medicinal  Products  grants  orphan  drug  designation  to  promote  the  development  of  products  that  are  intended  for  the  diagnosis,
prevention,  or  treatment  of  a  life-threatening  or  chronically  debilitating  condition  affecting  not  more  than  five  in  10,000  persons  in  the  European  Union.
Additionally, designation is granted for products intended for the diagnosis, prevention, or treatment of a life-threatening, seriously debilitating or serious and
chronic condition when, without incentives, it is unlikely that sales of the drug in the European Union would be sufficient to justify the necessary investment
in developing the drug or biological product or where there is no satisfactory method of diagnosis, prevention, or treatment, or, if such a method exists, the
medicine must be of significant benefit to those affected by the condition.

In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax
advantages, and user-fee waivers. In addition, if a product receives the first FDA approval for the indication for which it has orphan designation, the product
is entitled to orphan drug exclusivity, which means the FDA may not approve any other application to market the same drug for the same indication for a
period  of  seven  years,  except  in  limited  circumstances,  such  as  a  showing  of  clinical  superiority  over  the  product  with  orphan  exclusivity  or  where  the
manufacturer is unable to assure sufficient product quantity. In the European Union, orphan drug designation entitles a party to financial incentives such as
reduction of fees or fee waivers and ten years of market exclusivity following drug or biological product approval. This period may be reduced to six years if
the orphan drug designation criteria are no longer met, including where it is shown that the product is sufficiently profitable not to justify maintenance of
market exclusivity.

Even though we have orphan drug designation for SGX301 in the United States and Europe, and SGX203, RiVax® and OrbeShield® in the United States, we
may not be the first to obtain marketing approval for any particular orphan indication due to the uncertainties associated with developing drugs or biologic
products. 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. Absent patent or other intellectual property protection, even after an
orphan  drug  is  approved,  the  FDA  or  European  Medicines  Agency  may  subsequently  approve  the  same  drug  with  the  same  active  moiety  for  the  same
condition if the FDA or European Medicines Agency concludes that the later drug is safer, more effective, or makes a major contribution to patient care.

Federal and/or state health care reform initiatives could negatively affect our business.

The availability of reimbursement by governmental and other third-party payers affects the market for any pharmaceutical product. These third-party payers
continually attempt to contain or reduce the costs of healthcare. There have been a number of legislative and regulatory proposals to change the healthcare
system  and  further  proposals  are  likely.  Medicare’s  policies  may  decrease  the  market  for  our  products.  Significant  uncertainty  exists  with  respect  to  the
reimbursement status of newly approved healthcare products.

33

 
 
 
 
 
 
 
 
 
 
 
 
 
Third-party payers are increasingly challenging the price and cost-effectiveness of medical products and services. Once approved, we might not be able to sell
our products profitably or recoup the value of our investment in product development if reimbursement is unavailable or limited in scope, particularly for
product candidates addressing small patient populations. On July 15, 2008, the Medicare Improvements for Patients and Providers Act of 2008 became law
with  a  number  of  Medicare  and  Medicaid  reforms  to  establish  a  bundled  Medicare  payment  rate  that  includes  services  and  drug/labs  that  were  separately
billed at that time. Bundling initiatives that have been implemented in other healthcare settings have occasionally resulted in lower utilization of services that
had not previously been a part of the bundled payment.

In addition, in some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing
drug  pricing  vary  widely  from  country  to  country.  We  expect  that  there  will  continue  to  be  a  number  of  U.S.  federal  and  state  proposals  to  implement
governmental pricing controls. While we cannot predict whether such legislative or regulatory proposals will be adopted, the adoption of such proposals could
have a material adverse effect on our business, financial condition and profitability.

We may not be able to retain rights licensed to us by third parties to commercialize key products or to develop the third party relationships we need to
develop, manufacture and market our products.

We currently rely on license agreements from New York University, Yeda Research and Development Company Ltd., the University of Texas Southwestern
Medical Center, the University of British Columbia, Harvard University and George B. McDonald, MD as well as sublicense agreement from VitriVax for the
rights to commercialize key product candidates. We may not be able to retain the rights granted under these agreements or negotiate additional agreements on
reasonable terms, if at all. Our existing license agreements impose, and we expect that future license agreements will impose, various diligence, milestone
payment, royalty, and other obligations on us. If we fail to comply with our obligations under these agreements, or we are subject to a bankruptcy, we may be
required to make certain payments to the licensor, we may lose the exclusivity of our license, or the licensor may have the right to terminate the license, in
which event we would not be able to develop or market products covered by the license.

Additionally, the milestone and other payments associated with these licenses will make it less profitable for us to develop our drug candidates. See “Business
- Patents and Other Proprietary Rights” for a description of our license agreements.

Licensing  of  intellectual  property  is  of  critical  importance  to  our  business  and  involves  complex  legal,  business,  and  scientific  issues.  Disputes  may  arise
regarding intellectual property subject to a licensing agreement, including but not limited to:

● the scope of rights granted under the license agreement and other interpretation-related issues;

● the extent to which our technology and processes infringe on intellectual property of the licensor that is not subject to the licensing agreement;

● the sublicensing of patent and other rights;

● our diligence obligations under the license agreement and what activities satisfy those diligence obligations;

● the  ownership  of  inventions  and  know-how  resulting  from  the  joint  creation  or  use  of  intellectual  property  by  our  licensors  and  us  and  our

collaborators; and

● the priority of invention of patented technology.

If disputes over intellectual property and other rights that we have licensed prevent or impair our ability to maintain our current licensing arrangements on
acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates.

34

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Additionally, the research resulting in certain of our licensed patent rights and technology was funded by the U.S. government. As a result, the government
may  have  certain  rights,  or  march-in  rights,  to  such  patent  rights  and  technology.  When  new  technologies  are  developed  with  government  funding,  the
government generally obtains certain rights in any resulting patents, including a non-exclusive license authorizing the government to use the invention for
non-commercial  purposes.  The  government  can  exercise  its  march-in  rights  if  it  determines  that  action  is  necessary  because  we  fail  to  achieve  practical
application of the government-funded technology, because action is necessary to alleviate health or safety needs, to meet requirements of federal regulations
or to give preference to U.S. industry. In addition, our rights in such inventions may be subject to certain requirements to manufacture products embodying
such inventions in the United States. Any exercise by the government of such rights could harm our competitive position, business, financial condition, results
of operations and prospects.

Furthermore,  we  currently  have  very  limited  product  development  capabilities  and  no  manufacturing,  marketing  or  sales  capabilities.  For  us  to  research,
develop  and  test  our  product  candidates,  we  need  to  contract  or  partner  with  outside  researchers,  in  most  cases  with  or  through  those  parties  that  did  the
original research and from whom we have licensed the technologies. If products are successfully developed and approved for commercialization, then we will
need to enter into additional collaboration and other agreements with third parties to manufacture and market our products. We may not be able to induce the
third parties to enter into these agreements, and, even if we are able to do so, the terms of these agreements may not be favorable to us. Our inability to enter
into  these  agreements  could  delay  or  preclude  the  development,  manufacture  and/or  marketing  of  some  of  our  product  candidates  or  could  significantly
increase  the  costs  of  doing  so.  In  the  future,  we  may  grant  to  our  development  partners  rights  to  license  and  commercialize  pharmaceutical  and  related
products developed under the agreements with them, and these rights may limit our flexibility in considering alternatives for the commercialization of these
products. Furthermore, third-party manufacturers or suppliers may not be able to meet our needs with respect to timing, quantity and quality for the products.

Additionally, if we do not enter into relationships with additional third parties for the marketing of our products, if and when they are approved and ready for
commercialization,  we  would  have  to  build  our  own  sales  force  or  enter  into  commercialization  agreements  with  other  companies.  Development  of  an
effective sales force in any part of the world would require significant financial resources, time and expertise. We may not be able to obtain the financing
necessary to establish a sales force in a timely or cost effective manner, if at all, and any sales force we are able to establish may not be capable of generating
demand for our product candidates, if they are approved.

We may suffer product and other liability claims; we maintain only limited product liability insurance, which may not be sufficient.

The clinical testing, manufacture and sale of our products involves an inherent risk that human subjects in clinical testing or consumers of our products may
suffer serious bodily injury or death due to side effects, allergic reactions or other unintended negative reactions to our products. As a result, product and other
liability claims may be brought against us. We currently have clinical trial and product liability insurance with limits of liability of $10 million, which may
not be sufficient to cover our potential liabilities. Because liability insurance is expensive and difficult to obtain, we may not be able to maintain existing
insurance or obtain additional liability insurance on acceptable terms or with adequate coverage against potential liabilities. Furthermore, if any claims are
brought against us, even if we are fully covered by insurance, we may suffer harm such as adverse publicity.

We may use hazardous chemicals in our business. Potential claims relating to improper handling, storage or disposal of these chemicals could affect us
and be time consuming and costly.

Our research and development processes and/or those of our third party contractors involve the controlled use of hazardous materials and chemicals. These
hazardous chemicals are reagents and solvents typically found in a chemistry laboratory. Our operations also may produce hazardous waste products. Federal,
state and local laws and regulations govern the use, manufacture, storage, handling and disposal of hazardous materials. While we attempt to comply with all
environmental  laws  and  regulations,  including  those  relating  to  the  outsourcing  of  the  disposal  of  all  hazardous  chemicals  and  waste  products,  we  cannot
eliminate the risk of contamination from or discharge of hazardous materials and any resultant injury. In the event of such an accident, we could be held liable
for any resulting damages and any liability could materially adversely affect our business, financial condition and results of operations.

35

 
 
 
 
 
 
 
 
 
Compliance with environmental laws and regulations may be expensive. Current or future environmental regulations may impair our research, development
or production efforts. We might have to pay civil damages in the event of an improper or unauthorized release of, or exposure of individuals to, hazardous
materials. We are not insured against these environmental risks. We may agree to indemnify our collaborators in some circumstances against damages and
other liabilities arising out of development activities or products produced in connection with these collaborations.

In  addition,  the  federal,  state  and  local  laws  and  regulations  governing  the  use,  manufacture,  storage,  handling  and  disposal  of  hazardous  or  radioactive
materials and waste products may require us to incur substantial compliance costs that could materially adversely affect our business, financial condition and
results of operations.

We may not be able to compete with our larger and better financed competitors in the biotechnology industry.

The  biotechnology  industry  is  intensely  competitive,  subject  to  rapid  change  and  sensitive  to  new  product  introductions  or  enhancements.  Most  of  our
existing  competitors  have  greater  financial  resources,  larger  technical  staffs,  and  larger  research  budgets  than  we  have,  as  well  as  greater  experience  in
developing products and conducting clinical trials. Our competition is particularly intense in the gastroenterology and transplant areas and is also intense in
the  therapeutic  area  of  inflammatory  bowel  diseases.  We  face  intense  competition  in  the  biodefense  area  from  various  public  and  private  companies  and
universities as well as governmental agencies, such as the U.S. Army, which may have their own proprietary technologies that may directly compete with our
technologies. In addition, there may be other companies that are currently developing competitive technologies and products or that may in the future develop
technologies and products that are comparable or superior to our technologies and products. We may not be able to compete with our existing and future
competitors, which could lead to the failure of our business.

Additionally, if a competitor receives FDA approval before we do for a drug that is similar to one of our product candidates, FDA approval for our product
candidate may be precluded or delayed due to periods of non-patent exclusivity and/or the listing with the FDA by the competitor of patents covering its
newly-approved drug product. Periods of non-patent exclusivity for new versions of existing drugs such as our current product candidates can extend up to
three and one-half years. See “Business - The Drug Approval Process.”

These competitive factors could require us to conduct substantial new research and development activities to establish new product targets, which would be
costly and time consuming. These activities would adversely affect our ability to commercialize products and achieve revenue and profits.

Competition and technological change may make our product candidates and technologies less attractive or obsolete.

We  compete  with  established  pharmaceutical  and  biotechnology  companies  that  are  pursuing  other  forms  of  treatment  for  the  same  indications  we  are
pursuing and that have greater financial and other resources. Other companies may succeed in developing products earlier than us, obtaining FDA approval
for products more rapidly, or developing products that are more effective than our product candidates. Research and development by others may render our
technology or product candidates obsolete or noncompetitive, or result in treatments or cures superior to any therapy we develop. We face competition from
companies  that  internally  develop  competing  technology  or  acquire  competing  technology  from  universities  and  other  research  institutions.  As  these
companies develop their technologies, they may develop competitive positions that may prevent, make futile, or limit our product commercialization efforts,
which would result in a decrease in the revenue we would be able to derive from the sale of any products.

There  can  be  no  assurance  that  any  of  our  product  candidates  will  be  accepted  by  the  marketplace  as  readily  as  these  or  other  competing  treatments.
Furthermore, if our competitors’ products are approved before ours, it could be more difficult for us to obtain approval from the FDA. Even if our products
are successfully developed and approved for use by all governing regulatory bodies, there can be no assurance that physicians and patients will accept our
product(s) as a treatment of choice.

36

 
 
 
 
 
 
 
 
 
 
 
Furthermore,  the  pharmaceutical  research  industry  is  diverse,  complex,  and  rapidly  changing.  By  its  nature,  the  business  risks  associated  therewith  are
numerous and significant. The effects of competition, intellectual property disputes, market acceptance, and FDA regulations preclude us from forecasting
revenues or income with certainty or even confidence.

 Our business could be harmed if we fail to retain our current personnel or if they are unable to effectively run our business.

We currently have 16 employees and we depend upon these employees, in particular Dr. Christopher Schaber, our President and Chief Executive Officer, to
manage the day-to-day activities of our business. Because we have such limited personnel, the loss of any of them or our inability to attract and retain other
qualified employees in a timely manner would likely have a negative impact on our operations. We may be unable to effectively manage and operate our
business, and our business may suffer, if we lose the services of our employees.

Instability and volatility in the financial markets could have a negative impact on our business, financial condition, results of operations, and cash flows.

During  recent  years,  there  has  been  substantial  volatility  in  financial  markets  due  at  least  in  part  to  the  uncertainty  with  regard  to  the  global  economic
environment. In addition, there has been substantial uncertainty in the capital markets and access to additional financing is uncertain. Moreover, customer
spending  habits  may  be  adversely  affected  by  current  and  future  economic  conditions.  These  conditions  could  have  an  adverse  effect  on  our  industry  and
business, including our financial condition, results of operations, and cash flows.

To  the  extent  that  we  do  not  generate  sufficient  cash  from  operations,  we  may  need  to  issue  stock  or  incur  indebtedness  to  finance  our  plans  for  growth.
Recent turmoil in the credit markets and the potential impact on the liquidity of major financial institutions may have an adverse effect on our ability to fund
our  business  strategy  through  borrowings,  under  either  existing  or  newly  created  instruments  in  the  public  or  private  markets  on  terms  we  believe  to  be
reasonable, if at all.

We may not be able to utilize all of our net operating loss carryforwards.

The  State  of  New  Jersey’s  Technology  Business  Tax  Certificate  Program  allows  certain  high  technology  and  biotechnology  companies  to  sell  unused  net
operating  loss  (“NOL”)  carryforwards  to  other  New  Jersey-based  corporate  taxpayers.  In  accordance  with  this  program,  for  the  year  ended  December  31,
2016, we sold New Jersey NOL carryforwards, resulting in the recognition of $416,810 of income tax benefit. The Company has not yet sold its 2017 New
Jersey  NOLs  but  may  do  so  in  the  future.  If  there  is  an  unfavorable  change  in  the  State  of  New  Jersey’s  Technology  Business  Tax  Certificate  Program
(whether  as  a  result  of  a  change  in  law,  policy  or  otherwise)  that  terminates  the  program  or  eliminates  or  reduces  our  ability  to  use  or  sell  our  NOL
carryforwards, or if we are unable to find a suitable buyer to utilize our New Jersey NOL carryforwards to the extent the NOLs expire before we are able to
utilize them against our taxable income, our cash taxes may increase which may have an adverse effect on our financial condition.

Risks Related to our Intellectual Property

We  may  be  unable  to  commercialize  our  products  if  we  are  unable  to  protect  our  proprietary  rights,  and  we  may  be  liable  for  significant  costs  and
damages if we face a claim of intellectual property infringement by a third party.

Our near and long-term prospects depend in part on our ability to obtain and maintain patents, protect trade secrets and operate without infringing upon the
proprietary rights of others. In the absence of patent and trade secret protection, competitors may adversely affect our business by independently developing
and marketing substantially equivalent or superior products and technology, possibly at lower prices. We could also incur substantial costs in litigation and
suffer diversion of attention of technical and management personnel if we are required to defend ourselves in intellectual property infringement suits brought
by third parties, with or without merit, or if we are required to initiate litigation against others to protect or assert our intellectual property rights. Moreover,
any such litigation may not be resolved in our favor.

37

 
 
 
 
 
 
 
 
 
 
 
 
 
Although we and our licensors have filed various patent applications covering the uses of our product candidates, patents may not be issued from the patent
applications already filed or from applications that we might file in the future. Moreover, the patent position of companies in the pharmaceutical industry
generally involves complex legal and factual questions, and has been the subject of much litigation. Any patents we own or license, now or in the future, may
be challenged, invalidated or circumvented. To date, no consistent policy has been developed in the U.S. Patent and Trademark Office (the “PTO”) regarding
the breadth of claims allowed in biotechnology patents.

In addition, because patent applications in the U.S. are maintained in secrecy until patent applications publish or patents issue, and because publication of
discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain that we and our licensors are the first creators of
inventions covered by any licensed patent applications or patents or that we or they are the first to file. The PTO may commence interference proceedings
involving patents or patent applications, in which the question of first inventorship is contested. Accordingly, the patents owned or licensed to us may not be
valid or may not afford us protection against competitors with similar technology, and the patent applications licensed to us may not result in the issuance of
patents.

It  is  also  possible  that  our  owned  and  licensed  technologies  may  infringe  on  patents  or  other  rights  owned  by  others,  and  licenses  to  which  may  not  be
available to us. We may be unable to obtain a license under such patent on terms favorable to us, if at all. We may have to alter our products or processes, pay
licensing fees or cease activities altogether because of patent rights of third parties.

In addition to the products for which we have patents or have filed patent applications, we rely upon unpatented proprietary technology and may not be able
to meaningfully protect our rights with regard to that unpatented proprietary technology. Furthermore, to the extent that consultants, key employees or other
third parties apply technological information developed by them or by others to any of our proposed projects, disputes may arise as to the proprietary rights to
this information, which may not be resolved in our favor.

We may be involved in lawsuits to protect or enforce our patents, which could be expensive and time consuming.

The  pharmaceutical  industry  has  been  characterized  by  extensive  litigation  regarding  patents  and  other  intellectual  property  rights,  and  companies  have
employed intellectual property litigation to gain a competitive advantage. We may become subject to infringement claims or litigation arising out of patents
and pending applications of our competitors, or additional interference proceedings declared by the PTO to determine the priority of inventions. The defense
and prosecution of intellectual property suits, PTO proceedings, and related legal and administrative proceedings are costly and time-consuming to pursue,
and  their  outcome  is  uncertain.  Litigation  may  be  necessary  to  enforce  our  issued  patents,  to  protect  our  trade  secrets  and  know-how,  or  to  determine  the
enforceability,  scope,  and  validity  of  the  proprietary  rights  of  others.  An  adverse  determination  in  litigation  or  interference  proceedings  to  which  we  may
become a party could subject us to significant liabilities, require us to obtain licenses from third parties, or restrict or prevent us from selling our products in
certain markets. Although patent and intellectual property disputes might be settled through licensing or similar arrangements, the costs associated with such
arrangements may be substantial and could include our paying large fixed payments and ongoing royalties. Furthermore, the necessary licenses may not be
available on satisfactory terms or at all.

Competitors may infringe our patents, and we may file infringement claims to counter infringement or unauthorized use. This can be expensive, particularly
for  a  company  of  our  size,  and  time-consuming.  In  addition,  in  an  infringement  proceeding,  a  court  may  decide  that  a  patent  of  ours  is  not  valid  or  is
unenforceable or may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover its technology. An adverse
determination of any litigation or defense proceedings could put one or more of our patents at risk of being invalidated or interpreted narrowly.

38

 
 
 
 
 
 
 
 
 
Also, a third party may assert that our patents are invalid and/or unenforceable. There are no unresolved communications, allegations, complaints or threats of
litigation related to the possibility that our patents are invalid or unenforceable. Any litigation or claims against us, whether or not merited, may result in
substantial costs, place a significant strain on our financial resources, divert the attention of management and harm our reputation. An adverse decision in
litigation could result in inadequate protection for our product candidates and/or reduce the value of any license agreements we have with third parties.

Interference  proceedings  brought  before  the  PTO  may  be  necessary  to  determine  priority  of  invention  with  respect  to  our  patents  or  patent  applications.
During an interference proceeding, it may be determined that we do not have priority of invention for one or more aspects in our patents or patent applications
and could result in the invalidation in part or whole of a patent or could put a patent application at risk of not issuing. Even if successful, an interference
proceeding may result in substantial costs and distraction to our management.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation or interference proceedings, there is a
risk  that  some  of  our  confidential  information  could  be  compromised  by  disclosure.  In  addition,  there  could  be  public  announcements  of  the  results  of
hearings, motions or other interim proceedings or developments. If investors perceive these results to be negative, the price of our common stock could be
adversely affected.

If we infringe the rights of third parties we could be prevented from selling products, forced to pay damages, and defend against litigation.

If our products, methods, processes and other technologies infringe the proprietary rights of other parties, we could incur substantial costs and we may have
to: obtain licenses, which may not be available on commercially reasonable terms, if at all; abandon an infringing product candidate; redesign our products or
processes to avoid infringement; stop using the subject matter claimed in the patents held by others; pay damages; and/or defend litigation or administrative
proceedings which may be costly whether we win or lose, and which could result in a substantial diversion of our financial and management resources. 

Risks Related to our Securities

The price of our common stock and warrants may be highly volatile.

The market price of our securities, like that of many other research and development public pharmaceutical and biotechnology companies, has been highly
volatile and the price of our common stock and warrants may be volatile in the future due to a wide variety of factors, including:

● announcements by us or others of results of pre-clinical testing and clinical trials;

● announcements of technological innovations, more important bio-threats or new commercial therapeutic products by us, our collaborative partners or

our present or potential competitors;

● failure of  our  common  stock  or  warrants  to  continue  to  be  listed  or  quoted  on  a  national  exchange  or  market  system,  such  as  The  Nasdaq  Stock

Market (“NASDAQ”) or NYSE Amex LLC;

● our quarterly operating results and performance;

● developments or disputes concerning patents or other proprietary rights;

● acquisitions;

● litigation and government proceedings;

● adverse legislation;

● changes in government regulations;

39

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● our available working capital;

● economic and other external factors;

● general market conditions.

Since  January  1,  2018,  the  closing  stock  price  of  our  common  stock  has  fluctuated  between  a  high  of  $2.40  per  share  to  a  low  of  $0.85  per  share.  Since
January 1, 2018, the closing price of our common stock warrants has fluctuated between a high of $0.81 per warrant to a low of $0.13 per warrant. On March
20, 2019 the last reported sales prices of our common stock and our common stock warrant on The Nasdaq Capital Market were $1.01 per share and $0.20 per
warrant. The fluctuation in the price of our common stock and warrants has sometimes been unrelated or disproportionate to our operating performance. In
addition, potential dilutive effects of future sales of shares of common stock and warrants by us, as well as potential sale of common stock by the holders of
warrants and options, could have an adverse effect on the market price of our shares.

We are not currently in compliance with the continued listing requirements for The Nasdaq Capital Market. If the price of our common stock continues to
trade below $1.00 per share for a sustained period or we do not meet other continued listing requirements, our common stock may be delisted from The
Nasdaq Capital Market, which could affect the market price and liquidity for our common stock and reduce our ability to raise additional capital.

Our  common  stock  is  listed  on  The  Nasdaq  Capital  Market.  In  order  to  maintain  that  listing,  we  must  satisfy  minimum  financial  and  other  requirements
including, without limitation, a requirement that our closing bid price be at least $1.00 per share. On March 11, 2018, we received a written notice from The
Nasdaq Stock Market indicating that we are not in compliance with the minimum bid price requirement for continued listing on The Nasdaq Capital Market.
We have until September 9, 2019 to regain compliance. We can regain compliance if at any time prior to September 9, 2019 the bid price of our common
stock closes at or above $1.00 per share for a minimum of ten consecutive business days.

If we fail to regain compliance with the minimum bid price requirement by September 9, 2019, we may be afforded an additional 180-day period to regain
compliance  provided  that  (i)  we  meet  the  applicable  market  value  of  publicly  held  shares  requirement  for  continued  listing  and  all  other  applicable
requirements  for  initial  listing  on  The  Nasdaq  Capital  Market  (except  for  the  bid  price  requirement)  based  on  our  most  recent  public  filings  and  market
information and (ii) we provide notice of our intent to cure the bid price requirement deficiency prior to the completion of the second 180-day compliance
period by effecting a reverse stock split, if necessary.

We anticipate that we will seek stockholder approval at our annual meeting in 2019 to grant discretionary authority to our board of directors to amend our
certificate of incorporation to effect a reverse split of our outstanding shares of common stock within a range of one share of common stock for every ten
shares of common stock to one share of common stock for every twenty shares of common stock, with the exact reverse split ratio to be decided and publicly
announced by the board of directors prior to the effective time of the amendment to our certificate of incorporation.

We intend to monitor the closing bid price of our common stock and consider our available options to resolve our noncompliance with the minimum bid price
requirement. There can be no assurance that we will be able to regain compliance with the minimum bid price requirement or that we will otherwise be in
compliance with other listing criteria. If we fail to regain compliance with the minimum bid requirement or to meet the other applicable continued listing
requirements for The Nasdaq Capital Market in the future and staff of The Nasdaq Stock Market determines to delist our common stock, the delisting could
adversely affect the market price and liquidity of our common stock and reduce our ability to raise additional capital. In addition, if our common stock is
delisted from The Nasdaq Capital Market and the trading price remains below $5.00 per share, trading in our common stock might also become subject to the
requirements  of  certain  rules  promulgated  under  the  Exchange  Act,  which  require  additional  disclosure  by  broker-dealers  in  connection  with  any  trade
involving a stock defined as a “penny stock” (generally, any equity security not listed on a national securities exchange that has a market price of less than
$5.00 per share, subject to certain exceptions).

40

 
 
 
 
 
 
 
 
 
 
 
If we fail to remain current with our listing requirements, we could be removed from The Nasdaq Capital Market, which would limit the ability of broker-
dealers to sell our securities and the ability of shareholders to sell their securities in the secondary market.

Companies trading on The Nasdaq Stock Market, such as our Company, must be reporting issuers under Section 12 of the Exchange Act, as amended, and
must meet the listing requirements in order to maintain the listing of common stock on The Nasdaq Capital Market. If we do not meet these requirements, the
market  liquidity  for  our  securities  could  be  severely  adversely  affected  by  limiting  the  ability  of  broker-dealers  to  sell  our  securities  and  the  ability  of
shareholders to sell their securities in the secondary market.

The warrants may not have any value.

The outstanding warrants do not confer any rights of common stock ownership on their holders, such as voting rights or the right to receive dividends, but
rather merely represent the right to acquire shares of common stock at a fixed price for a limited period of time. Specifically, the holders of the outstanding
warrants  may  exercise  their  right  to  acquire  the  common  stock  and  pay  the  per  share  exercise  price,  prior  to  the  expiration  date,  after  which  date  any
unexercised warrants will expire and have no further value. In the event our common stock does not exceed the exercise price of the warrants during the
period when the warrants are exercisable, the warrants may not have any value.

Shareholders may suffer substantial dilution related to issued stock warrants and options.

As of December 31, 2018, we had a number of agreements or obligations that may result in dilution to investors. These include:

● warrants to purchase a total of approximately 6,303,643 shares of our common stock at a current weighted average exercise price of approximately

$3.09;

● options to purchase approximately 1,022,095 shares of our common stock at a current weighted average exercise price of approximately $5.32; and

● The FBR Sales Agreement pursuant to which we may, but have no obligation to, sell up to an additional $8.5 million worth of our common stock as

of March 20, 2019.

We also have an incentive compensation plan for our management, employees and consultants. We have granted, and expect to grant in the future, options to
purchase shares of our common stock to our directors, employees and consultants. To the extent that warrants or options are exercised, our stockholders will
experience dilution and our stock price may decrease.

Our shares of common stock and warrants are thinly traded, so stockholders may be unable to sell at or near ask prices or at all if they need to sell shares
or warrants to raise money or otherwise desire to liquidate their shares.

Our common stock and warrants have from time to time been “thinly-traded,” meaning that the number of persons interested in purchasing our common stock
or warrants at or near ask prices at any given time may be relatively small or non-existent. This situation is attributable to a number of factors, including the
fact that we are a small company that is relatively unknown to stock analysts, stock brokers, institutional investors and others in the investment community
that generate or influence sales volume, and that even if we came to the attention of such persons, they tend to be risk-averse and would be reluctant to follow
an  unproven  company  such  as  ours  or  purchase  or  recommend  the  purchase  of  our  shares  until  such  time  as  we  become  more  seasoned  and  viable.  As  a
consequence, there may be periods of several days or more when trading activity in our shares is minimal or non-existent, as compared to a seasoned issuer
which has a large and steady volume of trading activity that will generally support continuous sales without an adverse effect on share price. We cannot give
stockholders any assurance that a broader or more active public trading market for our common shares and warrants will develop or be sustained, or that
current trading levels will be sustained.

We  do  not  currently  intend  to  pay  dividends  on  our  common  stock  in  the  foreseeable  future,  and  consequently,  our  stockholders’  ability  to  achieve  a
return on their investment will depend on appreciation in the price of our common stock.

We have never declared or paid cash dividends on our common stock and do not anticipate paying any cash dividends to holders of our common stock in the
foreseeable future. Consequently, our stockholders must rely on sales of their common stock and warrants after price appreciation, which may never occur, as
the only way to realize any future gains on their investments. There is no guarantee that shares of our common stock or warrants will appreciate in value or
even maintain the price at which our stockholders have purchased their shares.

41

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Upon our dissolution, our stockholders may not recoup all or any portion of their investment.

In the event of our liquidation, dissolution or winding-up, whether voluntary or involuntary, the proceeds and/or our assets remaining after giving effect to
such transaction, and the payment of all of our debts and liabilities will be distributed to the holders of common stock on a pro rata basis. There can be no
assurance that we will have available assets to pay to the holders of common stock, or any amounts, upon such a liquidation, dissolution or winding-up. In
this event, our stockholders could lose some or all of their investment. 

The issuance of our common stock pursuant to the terms of the asset purchase agreement with Hy Biopharma Inc. may cause dilution and the issuance
of such shares of common stock, or the perception that such issuances may occur, could cause the price of our common stock to fall.

On April 1, 2014, we entered into an option agreement pursuant to which Hy Biopharma granted us an option to purchase certain assets, properties and rights
(the “Hypericin Assets”) related to the development of Hy Biopharma’s synthetic hypericin product candidate for the treatment of CTCL, which we refer to as
SGX301,  from  Hy  Biopharma.  In  exchange  for  the  option,  we  paid  $50,000  in  cash  and  issued  4,307  shares  of  common  stock  in  the  aggregate  to  Hy
Biopharma  and  its  assignees.  We  subsequently  exercised  the  option,  and  on  September  3,  2014,  we  entered  into  an  asset  purchase  agreement  with  Hy
Biopharma, pursuant to which we purchased the Hypericin Assets. Pursuant to the purchase agreement, we paid $275,000 in cash and issued 184,912 shares
of common stock in the aggregate to Hy Biopharma and its assignees, and the licensors of the license agreement acquired from Hy Biopharma, and may issue
up to an aggregate of $10 million worth of our common stock (subject to a cap equal to 19.99% of our issued and outstanding common stock) in the aggregate
upon attainment of specified milestones. The next milestone payment will be payable if the Phase 3 clinical trial of SGX301 is successful in demonstrating
efficacy  and  safety  in  the  CTCL  patient  population.  Also  on  September  3,  2014,  we  entered  into  a  Registration  Rights  Agreement  with  Hy  Biopharma,
pursuant to which we have filed a registration statement with the SEC.

The number of shares that we may issue under the purchase agreement will fluctuate based on the market price of our common stock. Depending on market
liquidity at the time, the issuance of such shares may cause the trading price of our common stock to fall.

We  may  ultimately  issue  all,  some  or  none  of  the  additional  shares  of  our  common  stock  that  may  be  issued  pursuant  to  the  purchase  agreement.  We  are
required to register any shares issued pursuant to the purchase agreement for resale under the Securities Act of 1933, as amended. After any such shares are
registered,  the  holders  will  be  able  to  sell  all,  some  or  none  of  those  shares.  Therefore,  issuances  by  us  under  the  purchase  agreement  could  result  in
substantial dilution to the interests of other holders of our common stock. Additionally, the issuance of a substantial number of shares of our common stock
pursuant to the purchase agreement, or the anticipation of such issuances, could make it more difficult for us to sell equity or equity-related securities in the
future at a time and at a price that we might otherwise wish to effect sales.

Item 2. Properties

We currently lease approximately 6,200 square feet of office space at 29 Emmons Drive, Suite B-10 in Princeton, New Jersey pursuant to a lease that was
amended in October 2017 and expires in October 2020. This office space currently serves as our corporate headquarters. The rent for the first 12 months was
approximately $11,367 per month, or approximately $22.00 per square foot. The rent increased to approximately $11,625 per month, or approximately $22.50
per square foot, for the 12 months beginning November 1, 2018 and will increase to approximately $11,883 per month, or approximately $23.00 per square
foot, beginning November 1, 2019 for the remainder of the lease. Our office space is sufficient to satisfy our current needs.

Item 3. Legal Proceedings

From time to time, we are a party to claims and legal proceedings arising in the ordinary course of business. Our management evaluates our exposure to these
claims and proceedings individually and in the aggregate and allocates additional monies for potential losses on such litigation if it is possible to estimate the
amount of loss and if the amount of the loss is probable.

Our Business Overview

We are a late-stage biopharmaceutical company focused on developing and commercializing products to treat rare diseases where there is an unmet medical
need. We maintain two active business segments: BioTherapeutics and Vaccines/BioDefense.

Our BioTherapeutics business segment is developing a novel photodynamic therapy (SGX301) utilizing topical synthetic hypericin activated with safe visible
fluorescent light for the treatment of cutaneous T-cell lymphoma (“CTCL”), our first-in-class innate defense regulator technology, dusquetide (SGX942) for
the  treatment  of  oral  mucositis  in  head  and  neck  cancer,  and  proprietary  formulations  of  oral  beclomethasone  17,21-dipropionate  (“BDP”)  for  the
prevention/treatment  of  gastrointestinal  (“GI”)  disorders  characterized  by  severe  inflammation,  including  pediatric  Crohn’s  disease  (SGX203)  and  acute
radiation enteritis (SGX201).

Our  Vaccines/BioDefense  business  segment  includes  active  development  programs  for  RiVax®,  our  ricin  toxin  vaccine  candidate  and  SGX943,  our
therapeutic candidate for antibiotic resistant and emerging infectious disease. The development of our vaccine programs currently is supported by our heat
stabilization technology, known as ThermoVax®, under existing and on-going government contract funding. With the government contract from the National
Institute of Allergy and Infectious Diseases (“NIAID”), we will attempt to advance the development of RiVax® to protect against exposure to ricin toxin. 

An outline of our business strategy follows:

● Following positive interim analysis, complete enrollment and report final results in our pivotal Phase 3 clinical trial of SGX301 for the treatment of

CTCL;

● Continue enrollment of the pivotal Phase 3 clinical trial of SGX942 for the treatment of oral mucositis in head and neck cancer;

● Continue development of RiVax® in combination with our ThermoVax® technology to develop a new heat stable vaccine in biodefense with NIAID

funding support;

● Continue to apply for and secure additional government funding for each of our BioTherapeutics and Vaccines/BioDefense programs through grants,

contracts and/or procurements;

● Pursue business development opportunities for our pipeline programs, as well as explore merger/acquisition strategies; and

● Acquire or in-license new clinical-stage compounds for development..

Critical Accounting Policies

Our  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  are  based  upon  our  consolidated  financial  statements,  which  have  been
prepared in accordance with accounting principles generally accepted in the U.S. The preparation of these financial statements requires us to make estimates
and judgments that affect the reported amounts of assets, liabilities and expenses, and related disclosure of contingent assets and liabilities. We evaluate these
estimates and judgments on an on-going basis.

Revenue Recognition

The Company’s revenues are primarily generated from government contracts and grants. The revenue from government contracts and grants is based upon
subcontractor costs and internal costs incurred that are specifically covered by the contracts and grants, plus a facilities and administrative rate that provides
funding  for  overhead  expenses  and  management  fees.  These  revenues  are  recognized  when  expenses  have  been  incurred  by  subcontractors  or  when  the
Company incurs reimbursable internal expenses that are related to the government contracts and grants.

Research and Development Costs

Research  and  development  costs  are  charged  to  expense  when  incurred  in  accordance  with  FASB  ASC  730,  Research  and  Development.  Research  and
development  includes  costs  such  as  clinical  trial  expenses,  contracted  research  and  license  agreement  fees  with  no  alternative  future  use,  supplies  and
materials,  salaries,  share-based  compensation,  employee  benefits,  equipment  depreciation  and  allocation  of  various  corporate  costs.  Purchased  in-process
research and development expense represents the value assigned or paid for acquired research and development for which there is no alternative future use as
of the date of acquisition.

Share-Based Compensation

Stock options are issued with an exercise price equal to the market price on the date of grant. Stock options issued to directors upon re-election vest quarterly
for a period of one year (new director issuances are fully vested upon issuance). Stock options issued to employees generally vest 25% on the grant date, then
25%  each  subsequent  year  for  a  period  of  three  years.  These  options  have  a  ten  year  life  for  as  long  as  the  individuals  remain  employees  or  directors.  In
general, when an employee or director terminates their position, the options will expire within three months, unless otherwise extended by the Board.

From time to time, the Company issues restricted shares of common stock to vendors and consultants as compensation for services performed. Typically these
instruments vest upon issuance and therefore the entire share-based compensation expense is recognized upon issuance to the vendors and/or consultants.

Share-based  compensation  expense  for  options,  warrants  and  shares  of  common  stock  granted  to  non-employees  has  been  determined  in  accordance  with
FASB ASC 505-50, Equity-Based Payments to Non-Employees,  and  represents  the  fair  value  of  the  consideration  received,  or  the  fair  value  of  the  equity
instruments issued, whichever may be more reliably measured. For options that vest over future periods, the fair value of options granted to non-employees is
amortized as the options vest. The fair value is remeasured each reporting period until performance is complete.

The fair value of each option grant made during 2018 and 2017 was estimated on the date of each grant using the Black-Scholes option pricing model and is
amortized ratably over the option vesting periods, which approximates the service period.

Income Taxes

On December 22, 2017, the United States (“U.S.”) government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the
“Tax Act”). The Tax Act significantly revises U.S. corporate income taxation by, among other things, lowering the U.S. corporate income tax rate from 35.0%
to 21.0% effective January 1, 2018. Tax Reform did not have any impact to the tax provision due to the full valuation allowance on its deferred tax assets and
the most significant impact on its consolidated financial statements was the reduction of approximately $14 million for the deferred tax assets related to net
operating losses and other assets recorded in the 2017 financial statements. Such reduction was fully offset by changes to the Company’s valuation allowance.

In December 2017, the SEC issued Staff Accounting Bulletin 118, which allows a measurement period, not to exceed one year, to finalize the accounting for
the income tax impacts of the Tax Act. The accounting for the income tax impacts of the Tax Act is now complete, no additional adjustments were required.

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts
of existing assets and liabilities and their respective tax basis. A valuation allowance is established when it is more likely than not that all or a portion of a
deferred  tax  asset  will  not  be  realized.  A  review  of  all  available  positive  and  negative  evidence  is  considered,  including  the  Company’s  current  and  past
performance,  the  market  environment  in  which  the  Company  operates,  the  utilization  of  past  tax  credits,  and  the  length  of  carryback  and  carryforward
periods.  Deferred  tax  assets  and  liabilities  are  measured  utilizing  tax  rates  expected  to  apply  to  taxable  income  in  the  years  in  which  those  temporary
differences are expected to be recovered or settled. No current or deferred income taxes have been provided in 2018 due to the net operating losses incurred
by the Company since its inception. The Company recognizes accrued interest and penalties associated with uncertain tax positions, if any, as part of income
tax expense. There were no tax related interest and penalties recorded for the years of 2018 and 2017. Additionally, the Company has not recorded an asset for
unrecognized tax benefits or a liability for uncertain tax positions at December 31, 2018 and December 31, 2017.

Earnings Per Share

Basic earnings per share (“EPS”) excludes dilution and is computed by dividing income (loss) available to common stockholders by the weighted-average
number  of  common  shares  outstanding  for  the  period.  Diluted  EPS  reflects  the  potential  dilution  that  could  occur  if  securities  or  other  contracts  to  issue
common stock were exercised or converted into common stock or resulted in the issuance of common stock that shared in the earnings of the entity. Since
there  is  a  significant  number  of  options  and  warrants  outstanding,  fluctuations  in  the  actual  market  price  can  have  a  variety  of  results  for  each  period
presented.

Use of Estimates and Assumptions

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and
assumptions such as the fair value of warrants and stock options and recovery of the useful life of intangibles that affect the reported amounts in the financial
statements and accompanying notes. Actual results could differ from those estimates.

Material Changes in Results of Operations

Year Ended December 31, 2018 Compared to 2017

For the year ended December 31, 2018, we had a net loss of $8,899,975 as compared to a net loss of $7,147,083 for the prior year, representing an increased
loss of $1,752,892 or 25%. The increase in net loss is primarily due to increased expenditures incurred to support both the pivotal Phase 3 trial of SGX301 in
the treatment of cutaneous T-cell lymphoma and the pivotal Phase 3 trial of SGX942 in the treatment of oral mucositis in head and neck cancer. For the years
ended  December  31,  2018  and  2017,  revenues  and  associated  costs  related  to  government  contracts  and  grants  awarded  in  support  of  our  development  of
OrbeShield®  for  the  treatment  of  GI  ARS  and  RiVax®  and  other  development  programs.  For  the  year  ended  December  31,  2018,  we  had  revenues  of
$5,241,448 as compared to $5,432,472 for the prior year, representing a decrease of $191,024 or 4%. The decrease in revenues was primarily a result of the
completion of the NIAID contract for OrbeShield® during the first quarter of 2017, along with the expiration of the base period of the BARDA contract for
the development of OrbeShield®, with BARDA electing not to extend the current contract beyond the base period. This was partially offset by an increase in
grant  revenues  awarded  in  September  2017  to  support  the  development  of  SGX301  for  the  treatment  of  CTCL  and  SGX942  for  the  treatment  of  oral
mucositis in head and neck cancer.

We  incurred  costs  related  to  contract  and  grant  revenues  in  the  year  ended  December  31,  2018  and  2017  of  $4,597,715  and  $4,310,083,  respectively,
representing an increase of $287,632 or 7%. The increase in costs was primarily the result of the increased expenditures incurred to support the development
of RiVax®, in addition to the reimbursable costs incurred to support the two Phase 3 trials of SGX301 and SGX942.

Our gross profit for the year ended December 31, 2018 was $643,733 or 12%, as compared to $1,122,389 or 21% for the prior year, representing a decrease of
$478,656 or 43%. The decrease in gross profit and gross profit margin for the year ended December 31, 2018 is attributable to a smaller share of reimbursable
costs that were available for contracted fixed overhead reimbursement compared to the year ended December 31, 2017. Additionally, we received milestone
fees  during  the  year  ended  December  31,  2017  under  our  RiVax®  contract  with  NIAID.  There  were  no  similar  milestones  received  for  the  year  ended
December 31, 2018.

Research and development expenses increased by $1,243,921 or 23%, to $6,750,954 for the year ended December 31, 2018 as compared to $5,507,033 for the
prior year. The increase in research and development spending for the year ended December 31, 2018 was related to expenditures incurred in the expansion of
the Phase 3 clinical trial of SGX942 as well as the ongoing Phase 3 clinical trial of SGX301.

49

 
 
 
 
 
 
 
 
General and administrative expenses decreased $257,395 or 8%, to $2,951,760 for the year ended December 31, 2018, as compared to $3,209,155 for the
prior year. This decrease is primarily related to cost savings in professional fees and employee compensation expenses.

Interest income for the year ended December 31, 2018 was $159,006 as compared to $29,906 for the prior year, reflecting an increase of $129,100 or 432%.
The increase reflected primarily higher interest income on our cash position.

The  State  of  New  Jersey’s  Technology  Business  Tax  Certificate  Program  allows  certain  high  technology  and  biotechnology  companies  to  sell  unused  net
operating  loss  (“NOL”)  carryforwards  to  other  New  Jersey-based  corporate  taxpayers.  In  accordance  with  this  program,  for  the  year  ended  December  31,
2016, we sold New Jersey NOL carryforwards, resulting in the recognition of $416,810 of income tax benefit. The Company has not yet sold its 2017 New
Jersey NOLs but may do so in the future. We will continue to explore opportunities to sell unused NOL carryforwards for the year ended December 31, 2017.
However, there can be no assurance as to the continuation or magnitude of this program in future years.

Business Segments

We maintain two active business segments for the years ended December 31, 2018 and 2017: Vaccines/BioDefense and BioTherapeutics.

Revenues for the Vaccines/BioDefense business segment for the year ended December 31, 2018 were $4,156,641 as compared to $4,749,294 for the year
ended December 31, 2017, representing a decrease of $592,653 or 12%. The decrease in revenues was primarily the result of a decrease in revenue from the
RiVax® development program along with the completion of the NIAID contract and the BARDA base period contract during the first quarter of 2017 for the
development of OrbeShield®, with BARDA electing not to extend the current contract beyond the base period.

Revenues for the BioTherapeutics business segment for the year ended December 31, 2018 were $1,084,807 as compared to $683,178 for the year ended
December 31, 2017, representing an increase of $401,629 or 59%. The increase was due to reimbursable development activity under the two grants that were
awarded in the third quarter of 2017 in support of our pivotal Phase 3 trials of SGX301 and SGX942.

Loss from operations for the Vaccines/BioDefense business segment for the year ended December 31, 2018 was $237,640 as compared to income of $232,166
for the year ended December 31, 2017, representing an increased loss of $469,806 or 202%. Loss from operations is primarily attributable to our decrease in
gross margins related to our government contracts and grants. The decrease in gross margin for the year ended December 31, 2018 was a result of the smaller
share of reimbursable costs available for a fixed overhead component during the year ended December 31, 2018, in addition to milestone fees received during
the year ended December 31, 2017 that improved profitability. Loss from operations for the BioTherapeutics business segment for the year ended December
31,  2018  was  $5,439,294  as  compared  to  $4,181,811  for  the  year  ended  December  31,  2017,  representing  an  increased  loss  of  $1,257,483  or  30%.  This
increased  loss  is  due  primarily  to  expenses  incurred  in  the  expansion  of  the  pivotal  Phase  3  clinical  trial  of  SGX942  as  well  as  expenses  incurred  in  the
ongoing Phase 3 clinical trial of SGX301.

Amortization and depreciation expense for the Vaccines/BioDefense business segment for the year ended December 31, 2018 was $17,951 as compared to
$33,183  for  the  year  ended  December  31,  2017.  Amortization  and  depreciation  expense  for  the  BioTherapeutics  business  segment  for  the  year  ended
December 31, 2018 was $21,018 as compared to $30,614 for the year ended December 31, 2017. The decrease in amortization and depreciation expense was
the result of office furniture and equipment and patents becoming fully amortized during the year ended December 31, 2018.

Financial Condition and Liquidity

Cash and Working Capital

As of December 31, 2018, we had cash and cash equivalents of $8,983,717 as compared to $7,809,487 as of December 31, 2017, representing an increase of
$1,174,230 or 15%. As of December 31, 2018, we had working capital of $6,131,178, representing a decrease of $54,685 as compared to working capital of
$6,185,863  for  the  prior  year.  The  increase  in  cash  and  cash  equivalents  was  primarily  related  to  the  net  proceeds  from  our  July  2018  public  offering  of
approximately  $8.4  million.  The  decrease  in  working  capital  was  a  result  of  the  increased  expenditures  incurred  in  the  expansion  of  the  pivotal  Phase  3
clinical trial of SGX942 for the treatment of oral mucositis in head and neck cancer, as well as the ongoing Phase 3 clinical trial of SGX301.

Based on our current rate of cash outflows, cash on hand, proceeds from government contract and grant programs, proceeds available from the FBR Sales
Agreement., management believes that its current cash will be sufficient to meet the anticipated cash needs for working capital and capital expenditures for at
least the next twelve months from issuance of the financial statements.

Our plans with respect to our liquidity management include, but are not limited to, the following:

● We  have  up  to  $14.6  million  in  active  government  contract  funding  still  available  as  of  December  31,  2018  to  support  our  associated  research
programs through 2020 and beyond, provided the federal agencies exercise all options and do not elect to terminate the contracts for convenience.
We plan to submit additional contract and grant applications for further support of our programs with various funding agencies;

● We  have  continued  to  use  equity  instruments  to  provide  a  portion  of  the  compensation  due  to  vendors  and  collaboration  partners  and  expect  to

continue to do so for the foreseeable future;

● We  will  continue  to  pursue  Net  Operating  Loss  (“NOL”)  sales  in  the  state  of  New  Jersey  pursuant  to  its  Technology  Business  Tax  Certificate

Transfer Program if the program is available;

● We plan to pursue potential partnerships for pipeline programs. However, there can be no assurances that we can consummate such transactions;

● We have up to $8.5 million remaining from the FBR Sales Agreement as of March 20, 2019 under the prospectus supplement updated October 3,

2018; and

● We may seek additional capital in the private and/or public equity markets, pursue government contracts and grants as well as business development
activities,  to  continue  our  operations,  respond  to  competitive  pressures,  develop  new  products  and  services,  and  to  support  new  strategic
partnerships.  We  are  currently  evaluating  additional  equity/debt  financing  opportunities  on  an  ongoing  basis  and  may  execute  them  when
appropriate. However, there can be no assurances that we can consummate such a transaction, or consummate a transaction at favorable pricing.

Expenditures

Under our budget and based upon our existing product development agreements and license agreements pursuant to letters of intent and option agreements,
we expect our total research and development expenditures for the year ending December 31, 2019, to be approximately $9.3 million before any contract or
grant  reimbursements,  of  which  $7.2  million  relates  to  the  BioTherapeutics  business  and  $2.1  million  relates  to  the  Vaccines/BioDefense  business.  We
anticipate  contract  and  grant  reimbursements  for  the  same  period  of  approximately  $3.3  million  to  offset  research  and  development  expenses  in  the
BioTherapeutics and Vaccines/BioDefense business segments.

We  have  licensing  fee  commitments  of  approximately  $500,000  for  the  next  five  years  for  several  licensing  agreements  with  consultants  and  universities.
Additionally, we have collaboration and license agreements, which upon clinical or commercialization success may require the payment of milestones of up
to  $7.9  million  and/or  royalties  up  to  6%  of  net  sales  of  covered  products,  if  and  when  achieved.  However,  there  can  be  no  assurance  that  clinical  or
commercialization success will occur.

We currently lease approximately 6,200 square feet of office space at 29 Emmons Drive, Suite B-10 in Princeton, New Jersey pursuant to a lease that was
amended in October 2017 and expires in October 2020. This office space currently serves as our corporate headquarters. The rent for the first 12 months was
approximately $11,367 per month, or approximately $22.00 per square foot. The rent increased to approximately $11,625 per month, or approximately $22.50
per  square  foot,  for  the  12  months  beginning  November  1,  2018  and  will  increase  to  approximately  $11,883  per  month  on  November  1,  2019,  or
approximately $23.00 per square foot for the remainder of the lease. Our office space is sufficient to satisfy our current needs.

On  September  3,  2014,  we  entered  into  an  asset  purchase  agreement  with  Hy  Biopharma,  Inc.  (“Hy  Biopharma”)  pursuant  to  which  we  acquired  certain
intangible assets, properties and rights of Hy Biopharma related to the development of Hy BioPharma’s synthetic hypericin product. As consideration for the
assets acquired, we paid $275,000 in cash and issued 184,912 shares of common stock with a fair value based upon our stock price on the date of grant of
$3,750,000. These amounts were charged to research and development expense during the third quarter of 2014 as the assets will be used in our research and
development activities and do not have alternative future use pursuant to generally accepted accounting principles in the United States. Provided all future
success-oriented milestones are attained, we will be required to make payments of up to $10.0 million, if and when achieved. Payments will be payable in
restricted securities of the Company not to exceed 19.9% ownership of our outstanding stock. As of December 31, 2018, no milestone payments have been
made or accrued.

In February 2007, our Board of Directors authorized the issuance of 5,000 shares of our common stock to Dr. Schaber immediately prior to the completion of
a transaction, or series or a combination of related transactions negotiated by our Board of Directors whereby, directly or indirectly, a majority of our capital
stock or a majority of our assets are transferred from us and/or our stockholders to a third party. Dr. Schaber’s amended employment agreement includes our
obligation to issue such shares if such event occurs.

As a result of the above agreements, we have future contractual obligations over the next five years as follows:

Item 8. Financial Statements and Supplementary Data

The information required by this Item 8 is contained on pages F-1 through F-24 of this Annual Report on Form 10-K and is incorporated herein by reference.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are the Company’s controls and other procedures that are designed to ensure that information required to be disclosed by
us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized and
reported  within  the  time  periods  specified  in  the  SEC’s  rules  and  forms.  Disclosure  controls  and  procedures  include,  without  limitation,  controls  and
procedures  designed  to  ensure  that  information  required  to  be  disclosed  by  us  in  the  reports  that  we  file  under  the  Exchange  Act  is  accumulated  and
communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding
required disclosure. Our management recognizes that any controls and procedures, no matter how well designed and operated, can only provide reasonable
assurance of achieving their objectives and management necessarily applies its judgment in evaluating the possible controls and procedures.

Our  management  has  evaluated,  with  the  participation  of  our  principal  executive  officer  and  principal  financial  officer,  the  effectiveness  of  our  disclosure
controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report.
Based upon that evaluation, our management, including our principal executive officer and principal financial officer, has concluded that, as of the end of the
period covered by this report, the Company’s disclosure controls and procedures were effective at the reasonable assurance level.

Management’s Annual Report on Internal Control over Financial Reporting

Company  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting.  Internal  control  over  financial
reporting is a process designed by, or under the supervision of, our principal executive and principal financial officers and effected by the Company’s Board
of Directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial
statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

·

·

·

pertain to  the  maintenance  of  records  that  in  reasonable  detail  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the
Company;

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally
accepted  accounting  principles,  and  that  receipts  and  expenditures  of  the  Company  are  being  made  only  in  accordance  with  authorizations  of
management and directors of the Company; and

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that
could have a material effect on the financial statements.

53

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

Management  assessed  the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting  as  of  December  31,  2018.  In  making  this  assessment,
management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control-Integrated
Framework, 2013.

Based on our assessment, management has concluded that, as of December 31, 2018, the Company’s internal control over financial reporting is effective.

Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal control over financial reporting identified in connection with the evaluation of such internal control that
occurred during the Company’s last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control
over financial reporting.

Item 9B. Other Information

On March 26, 2019, we entered into an amendment to our employment agreement with Richard C. Straube, MD, our Chief Medical Officer and Senior Vice
President. Pursuant to the amended agreement, which becomes effective April 1, 2019, Dr. Straube will be required to devote at least 20 hours per week to the
performance of his duties and we will pay him $170,000 per year. The amended employment agreement automatically renews each year, unless otherwise

Board Leadership Structure

Our Board of Directors believes that Dr. Schaber’s service as both the Chairman of our Board of Directors and our Chief Executive Officer is in the best
interest of our Company and our stockholders. Dr. Schaber possesses detailed and in-depth knowledge of the issues, opportunities and challenges facing our
Company and our business and, therefore, is best positioned to develop agendas that ensure that the Board of Directors’ time and attention are focused on the
most important matters. His combined role enables decisive leadership, ensures clear accountability, and enhances our ability to communicate our message
and strategy clearly and consistently to our stockholders, employees, and collaborative partners.

Messrs. Brownlie, Lapointe, Pearson, Dr. Rubin, and Dr. Zeldis are independent and the Board of Directors believes that the independent directors provide
effective  oversight  of  management.  Moreover,  in  addition  to  feedback  provided  during  the  course  of  meetings  of  the  Board  of  Directors,  the  independent
directors  hold  executive  sessions.  Following  an  executive  session  of  independent  directors,  the  independent  directors’  report  back  to  the  full  Board  of
Directors regarding any specific feedback or issues, provide the Chairman with input regarding agenda items for Board of Directors and Committee meetings,
and  coordinate  with  the  Chairman  regarding  information  to  be  provided  to  the  independent  directors  in  performing  their  duties.  The  Board  of  Directors
believes that this approach appropriately and effectively complements the combined Chairman/Chief Executive Officer structure.

Although we believes that the combination of the Chairman and Chief Executive Officer roles is appropriate under the current circumstances, our corporate
governance guidelines do not establish this approach as a policy, and the Board of Directors may determine that it is more appropriate to separate the roles in
the future.

Section 16(a) Beneficial Ownership Reporting Compliance

We are required to identify each person who was an officer, director or beneficial owner of more than 10% of our registered equity securities during our most
recent fiscal year and who failed to file on a timely basis reports required by Section 16(a) of the Exchange Act.

To  our  knowledge,  based  solely  on  review  of  these  filings  and  written  representations  from  the  certain  reporting  persons,  we  believe  that  during  the  year
ended December 31, 2017, our officers, directors and significant stockholders have timely filed the appropriate form under Section 16(a) of the Exchange
Act.

Committees of the Board of Directors

Our  Board  of  Directors  has  the  following  three  committees:  (1)  Compensation,  (2) Audit  and  (3)  Nominating  and  Corporate  Governance.  Our  Board  of
Directors has adopted a written charter for each of these committees, which are available on our website at www.soligenix.com under the “Investors” section.

Audit Committee

Our Board of Directors has an Audit Committee, which is comprised of Mr. Brownlie (Chair), Mr. Lapointe and Dr. Rubin. The Audit Committee assists our
Board of Directors in monitoring the financial reporting process, the internal control structure and the independent registered public accountants. Its primary
duties are to serve as an independent and objective party to monitor the financial reporting process and internal control system, to review and appraise the
audit  effort  of  the  independent  registered  public  accountants  and  to  provide  an  open  avenue  of  communication  among  the  independent  registered  public
accountants, financial and senior management, and our Board of Directors. Our Board of Directors has determined that Mr. Brownlie, Mr. Lapointe and Dr.
Rubin are “independent” directors, within the meaning of applicable listing standards of The Nasdaq Stock Market LLC (“Nasdaq”) and the Exchange Act
and the rules and regulations thereunder. Our Board of Directors has also determined that the members of the Audit Committee are qualified to serve on the
committee and have the experience and knowledge to perform the duties required of the committee and that Mr. Brownlie qualifies as an “audit committee
financial expert” as that term is defined in the applicable regulations of the Exchange Act.

Compensation Committee

Our Board of Directors has a Compensation Committee, which is comprised of Dr. Rubin (Chair), Mr. Pearson and Dr. Zeldis. The Compensation Committee
is responsible for reviewing and approving the executive compensation program, assessing executive performance, setting salary, making grants of annual
incentive compensation and approving certain employment agreements. Our Board of Directors has determined that Dr. Rubin, Mr. Pearson and Dr. Zeldis are
“independent” directors within the meaning of applicable listing standards of Nasdaq and the Exchange Act and the rules and regulations thereunder.

Nominating and Corporate Governance Committee

Our Board of Directors has a Nominating and Corporate Governance Committee (“Nominating Committee”), which is comprised of Dr. Zeldis (Chair), Mr.
Brownlie and Mr. Lapointe. The Nominating Committee makes recommendations to the Board of Directors regarding the size and composition of our Board
of Directors, establishes procedures for the nomination process, identifies and recommends candidates for election to our Board of Directors. Our Board of
Directors has determined that Dr. Zeldis, Mr. Brownlie and Mr. Lapointe are “independent” directors, as such term is defined by the applicable Nasdaq listing
standards.

Code of Ethics

We have adopted a code of ethics that applies to all of our executive officers and senior financial officers (including our chief executive officer, chief financial
officer,  chief  accounting  officer  and  any  person  performing  similar  functions).  A  copy  of  our  code  of  ethics  is  publicly  available  on  our  website  at
www.soligenix.com under the “Investors” section. If we make any substantive amendments to our code of ethics or grant any waiver, including any implicit
waiver,  from  a  provision  of  the  code  to  our  chief  executive  officer,  chief  financial  officer  or  chief  accounting  officer,  we  will  disclose  the  nature  of  such
amendment or waiver in a Current Report on Form 8-K.

Diversity Considerations in Identifying Director Nominees

We  do  not  have  a  formal  diversity  policy  or  set  of  guidelines  in  selecting  and  appointing  directors  that  comprise  our  Board  of  Directors.  However,  when
making recommendations to our Board of Directors regarding the size and composition of our Board of Directors, our Nominating Committee does consider
each individual director’s qualifications, skills, business experience and capacity to serve as a director and the diversity of these attributes for the Board of
Directors as a whole.

Compensation Committee Interlocks and Insider Participation

No member of our Compensation Committee is or has at any time during the past year been one of our officers or employees. None of our executive officers
currently  serves  or  in  the  past  year  has  served  as  a  member  of  the  Board  of  Directors  or  Compensation  Committee  of  any  entity  that  has  one  or  more
executive officers serving on our Board of Directors or Compensation Committee.

Item 11. Executive Compensation

In 2018, in furtherance of our compensation philosophy and objectives, the Compensation Committee engaged the Setren Smallberg & Associates (“SS&A”),
an outside executive compensation consulting firm determined to be independent by the Compensation Committee, to conduct a review of, and recommend
changes to, our compensation program for our most highly compensated executive officers. A representative of SS&A attended Compensation Committee
meetings  at  the  invitation  of  the  Compensation  Committee  Chairman  and  was  also  in  direct  contact  with  the  Compensation  Committee  and  company
management from time to time. SS&A provided the Compensation Committee with assistance and advice in the review of the Company’s salary structure,
annual and equity incentive awards and other related executive pay issues. In addition, SS&A provided advice regarding marketplace trends and best practices
relating to competitive pay levels.

SS&A did not provide any services to us other than its services as the Compensation Committee’s independent compensation consultant, and SS&A did not
receive any fees or compensation from us other than the fee it received as the independent compensation consultant. Except as described above, SS&A did
not provide any services to the Company in 2017 or 2018. The Compensation Committee confirmed that SS&A’s work for the Compensation Committee did
not create any conflicts of interest.

Employment and Severance Agreements

In August 2006, we entered into a three-year employment agreement with Christopher J. Schaber, PhD. Pursuant to this employment agreement we agreed to
pay Dr. Schaber a base salary of $300,000 per year and a minimum annual bonus of $100,000. Dr. Schaber’s employment agreement automatically renews
every three years, unless otherwise terminated, and was automatically renewed in December 2007, December 2010, December 2013 and December 2016 for
an additional term of three years. We agreed to issue him options to purchase 12,500 shares of our common stock, with one third immediately vesting and the
remainder  vesting  over  three  years.  Upon  termination  without  “Just  Cause”  as  defined  by  this  agreement,  we  would  pay  Dr.  Schaber  nine  months  of
severance,  as  well  as  any  accrued  bonuses,  accrued  vacation,  and  we  would  provide  health  insurance  and  life  insurance  benefits  for  Dr.  Schaber  and  his
dependents.  No  unvested  options  shall  vest  beyond  the  termination  date.  Dr.  Schaber’s  monetary  compensation  (base  salary  of  $300,000  and  bonus  of
$100,000) remained unchanged from 2006 with the 2007 renewal. Upon a change in control of the Company due to merger or acquisition, all of Dr. Schaber’s
options shall become fully vested, and be exercisable for a period of five years after such change in control (unless they would have expired sooner pursuant
to their terms). In the event of his death during the term of the agreement, all of his unvested options shall immediately vest and remain exercisable for the
remainder of their term and become the property of Dr. Schaber’s immediate family.

In February 2007, our Board of Directors authorized the issuance of 5,000 shares to Dr. Schaber immediately prior to the completion of a transaction, or series
or a combination of related transactions negotiated by our Board of Directors whereby, directly or indirectly, a majority of our capital stock or a majority of
our assets are transferred from us and/or our stockholders to a third party. The amended agreement with Dr. Schaber includes our obligation to issue such
shares to him if such event occurs.

2019, Dr. Straube will be required to devote at least 20 hours per week to the performance of his duties and we will pay him $170,000 per year. The amended
employment  agreement  automatically  renews  each  year,  unless  otherwise  terminated.  Upon  termination  without  “Just  Cause”,  as  defined  in  the  amended
employment agreement, we would pay Dr. Straube one month of severance. No unvested options vest beyond the termination date. On December 14, 2016,
the Compensation Committee approved an increase in salary for Dr. Straube to $323,060. On December 7, 2017, the Compensation Committee approved an

(1) Directors who  are  compensated  as  full-time  employees  receive  no  additional  compensation  for  service  on  our  Board  of  Directors.  Each  independent
director  who  is  not  a  full-time  employee  is  paid  $35,000  annually,  on  a  prorated  basis,  for  their  service  on  our  Board  of  Directors,  the  chairman  of
our Audit Committee is paid $15,000 annually, on a prorated basis, and the chairmen of our Compensation and Nominating Committees is paid $10,000
annually, on a prorated basis. Additionally, Audit Committee members are paid $7,500 annually and Compensation and Nominating Committee members
are paid $5,000 annually. This compensation is paid quarterly. During July 2018, Mr. Pearson was selected by the Nominating Committee and elected by
the Board as a Director. Dr. Brughera elected not to stand for re-election to the Board of Directors for the Annual meeting held on September 27, 2018.

(2) We maintain a stock option grant program pursuant to the nonqualified stock option plan, whereby members of our Board of Directors or its committees
who are not full-time employees receive an initial grant of fully vested options to purchase 1,500 shares of common stock. Upon re-election to the Board,
each Board member will receive stock options with a value of $30,000, calculated using the closing price of the common stock on the trading day prior to
the date of the annual meeting of our stockholders, which vest at the rate of 25% per quarter, commencing with the first quarter after each annual meeting
of stockholders.

Stock Ownership Policy

In April 2012, our Board of Directors adopted a stock ownership policy applicable to our non-employee directors to strengthen the link between director and
stockholder interests. Pursuant to the stock ownership policy, each non-employee director is required to hold a minimum ownership position in the common
stock equal to the annual cash compensation paid for service on the Board of Directors, exclusive of cash compensation paid for service as a chair or member
of any committees of the Board of Directors.

Stock counted toward the ownership requirement includes common stock held by the director, unvested and vested restricted stock, and all shares of common
stock  beneficially  owned  by  the  director  held  in  a  trust  and  by  a  spouse  and/or  minor  children  of  the  director.  The  policy  provides  that  the  ownership
requirement must be attained within three years after the later of June 21, 2012 and the date a director is first elected or appointed to the Board of Directors.
To  monitor  progress  toward  meeting  the  requirement,  the  Nominating  Committee  will  review  director  ownership  levels  at  the  end  of  March  of  each  year.
Non-employee directors are prohibited from selling any shares of common stock unless such director is in compliance with the stock ownership policy. A
copy of our director compensation and stock ownership policy is publicly available on our website at www.soligenix.com under the “Investors” section.

exercisable or exercisable within 60 days of March 20, 2019 are deemed outstanding for computing the percentage ownership of the stockholder holding

based on 18,189,208 shares of Common Stock outstanding as of March 20, 2019.

Equity Compensation Plan Information

In  December  2005,  our  Board  of  Directors  approved  the  2005  Equity  Incentive  Plan,  which  was  approved  by  stockholders  on  December  29,  2005.  In
September 2013, our stockholders approved an amendment to the 2005 Equity Incentive Plan to increase the maximum number of shares of our common
stock available for issuance under the plan by 125,000 shares, bringing the total shares reserved for issuance under the plan to 300,000 shares. In April 2015,
our Board of Directors approved the 2015 Equity Incentive Plan, which was approved by stockholders on June 18, 2015. . In June 2017, our stockholders
approved an amendment to the 2015 Plan to increase the maximum number of shares of our Common Stock available for issuance under the plan to 600,000
shares. In September 2018, our stockholders approved a second amendment to the 2015 Equity Incentive Plan to increase the maximum number of shares of
our common stock available for issuance under the plan, bringing the total shares available for issuance under the plan to 1,000,000 shares. The following
table provides information, as of December 31, 2018 with respect to options outstanding under our 2005 Equity Incentive Plan and our 2015 Equity Incentive

Item 13. Certain Relationships and Related Transactions and Director Independence

Related Party Transactions

Our  audit  committee  is  responsible  for  the  review,  approval  and  ratification  of  related  party  transactions.  The  audit  committee  reviews  these  transactions
under our Code of Ethics, which governs conflicts of interests, among other matters, and is applicable to our employees, officers and directors.

We  are  party  to  a  registration  rights  agreement  with  certain  stockholders,  including  Altamont  Pharmaceutical  Holdings,  LLC,  ACT  Capital  Management,
LLLP,  and  Knoll  Capital  Management,  LP,  each  of  which  beneficially  owns  5%  or  more  of  the  shares  of  our  outstanding  common  stock.  The  agreement
provides that the stockholders have the right to require that we register its shares under the Securities Act of 1933 (the “Securities Act”) for sale to the public,
subject  to  certain  conditions.  The  stockholders  also  have  piggyback  registration  rights,  which  means  that,  if  not  already  registered,  they  have  the  right  to
include  their  shares  in  any  registration  that  we  effect  under  the  Securities  Act,  subject  to  specified  exceptions.  We  must  pay  all  expenses  incurred  in
connection with the exercise of these demand registration rights.

We are unable to estimate the dollar value of the registration rights to the holders of these rights. The amount of reimbursable expenses under the agreements
depends on a number of variables, including whether registration rights are exercised incident to a primary offering by us, the form on which we are eligible
to register such a transaction, and whether we have a shelf registration in place at the time of a future offering.

Other than as described above, the employment agreements and compensation paid to our directors, we did not engage in any transactions with related parties
since January 1, 2017. For a discussion of our employment agreements and compensation paid to our directors, see “Item 11. Executive Compensation”.

Director Independence

The  Board  of  Directors  has  determined  that  Messrs.  Brownlie  and  Lapointe,  Dr.  Rubin,  and  Dr.  Zeldis  are  “independent”  as  such  term  is  defined  by  the
applicable  listing  standards  of  Nasdaq.  Our  Board  of  Directors  based  this  determination  primarily  on  a  review  of  the  responses  of  the  Directors  to
questionnaires regarding their employment, affiliations and family and other relationships.

Pre-Approval Policies and Procedures

The  audit  committee  has  adopted  a  policy  that  requires  advance  approval  of  all  audit  services  and  permitted  non-audit  services  to  be  provided  by  the
independent auditor as required by the Exchange Act. The audit committee must approve the permitted service before the independent auditor is engaged to
perform it. The audit committee approved all of the services described above in accordance with its pre-approval policies and procedures.

Basis of Presentation

Soligenix, Inc. (the “Company”) is a late-stage biopharmaceutical company focused on developing and commercializing products to treat rare diseases where

safe  visible  fluorescent  light  for  the  treatment  of  cutaneous  T-cell  lymphoma  (“CTCL”),  its  first-in-class  innate  defense  regulator  (“IDR”)  technology,
dusquetide (SGX942) for the treatment of oral mucositis in head and neck cancer, and proprietary formulations of oral beclomethasone 17,21-dipropionate
(“BDP”)  for  the  prevention/treatment  of  gastrointestinal  (“GI”)  disorders  characterized  by  severe  inflammation,  including  pediatric  Crohn’s  disease

The Company’s Vaccines/BioDefense business segment includes active development programs for RiVax®, its ricin toxin vaccine candidate and SGX943, a
therapeutic  candidate  for  antibiotic  resistant  and  emerging  infectious  disease.  The  development  of  the  vaccine  program  is  currently  supported  by  the  heat
stabilization technology, known as ThermoVax®, under existing and on-going government contract funding. With the government contract from the National
Institute of Allergy and Infectious Diseases (“NIAID”), the Company will attempt to advance the development of RiVax® to protect against exposure to ricin
toxin. 

The Company generates revenues under government grants primarily from the National Institutes of Health (“NIH”) and government contracts from NIAID.
The Company is currently developing RiVax® under a NIAID contract of up to $24.7 million over six years, and SGX301 and SGX942 under two separate
NIH grants of approximately $1.5 million each over two years. The Company will continue to apply for additional government funding.

The  Company  is  subject  to  risks  common  to  companies  in  the  biotechnology  industry  including,  but  not  limited  to,  development  of  new  technological
innovations, dependence on key personnel, protections of proprietary technology, compliance with the United States Food and Drug Administration (the U.S.
“FDA”) regulations, and other regulatory authorities, litigation, and product liability.

Liquidity

In  accordance  with  Accounting  Standards  Codification  205-40,  Going  Concern,  the  Company  has  evaluated  whether  there  are  conditions  and  events,
considered  in  the  aggregate,  that  raise  substantial  doubt  about  the  Company’s  ability  to  continue  as  a  going  concern  within  one  year  after  the  date  the
consolidated financial statements are issued. As of December 31, 2018, the Company had an accumulated deficit of $166,170,020. During the year ended
December 31, 2018, the Company incurred a net loss of $8,899,975 and used $7,244,631 of cash in operations. The Company expects to continue to generate
losses in the foreseeable future. The Company’s liquidity needs will be largely determined by the budgeted operational expenditures incurred in regards to the
progression of its product candidates. The Company’s plans to meet its liquidity needs primarily include its ability to control the timing and spending on its
research  and  development  programs  and  raising  additional  funds  through  potential  partnerships  and/or  financings.  Based  on  the  Company’s  approved
operating budget, current rate of cash outflows, cash on hand, proceeds from government contract and grant programs, and proceeds available from the At
Market Issuance Sales Agreement (“FBR Sales Agreement”) with B. Riley FBR, Inc. (“FBR”) management believes that its current cash will be sufficient to
meet the anticipated cash needs for working capital and capital expenditures for at least the next 12 months from issuance of the financial statements.

As of December 31, 2018, the Company had cash and cash equivalents of $8,983,717 as compared to $7,809,487 as of December 31, 2017, representing an
increase of $1,174,230 or 15%. As of December 31, 2018, the Company had working capital of $6,131,178, as compared to working capital of $6,185,863 for
the prior year, representing a decrease of $54,685. The increase in cash and cash equivalents was primarily the result of the Company’s financing activities
through  its  public  offering  of  common  stock.  The  decrease  in  working  capital  was  primarily  related  to  the  expenditures  incurred  in  the  expansion  of  the
pivotal Phase 3 trial of SGX942 in addition to the ongoing expenditures incurred in the pivotal Phase 3 clinical trial of SGX301.

Management’s business strategy can be outlined as follows:

● Following positive interim analysis, complete enrollment and report final results in the Company’s pivotal Phase 3 clinical trial of SGX301 for the

treatment of CTCL;

● Continue enrollment of the pivotal Phase 3 clinical trial of SGX942 for the treatment of oral mucositis in head and neck cancer;
● Continue development of RiVax® in combination with the Company’s ThermoVax® technology to develop a new heat stable vaccine in biodefense

with NIAID funding support;

● Continue to  apply  for  and  secure  additional  government  funding  for  each  of  the  Company’s  BioTherapeutics and Vaccines/BioDefense programs

through grants, contracts and/or procurements;

● Pursue business development opportunities for the Company’s pipeline programs, as well as explore merger/acquisition strategies; and
● Acquire or in-license new clinical-stage compounds for development.

The Company’s plans with respect to its liquidity management include, but are not limited to, the following:

● The  Company  has  up  to  $14.6  million  in  active  government  contract  and  grant  funding  still  available  as  of  December  31,  2018,  to  support  its
associated research programs through 2019 and beyond, provided the federal agencies exercise all options and do not elect to terminate the contracts
or grants for convenience. The Company plans to submit additional contract and grant applications for further support of its programs with various
funding agencies;

● The Company  has  continued  to  use  equity  instruments  to  provide  a  portion  of  the  compensation  due  to  vendors  and  collaboration  partners  and

expects to continue to do so for the foreseeable future;

● The  Company  will  continue  to  pursue  Net  Operating  Loss  (“NOL”)  sales  in  the  state  of  New  Jersey  pursuant  to  its  Technology  Business  Tax

Certificate Transfer Program if available;

● The Company  plans  to  pursue  potential  partnerships  for  pipeline  programs.  However,  there  can  be  no  assurances  that  we  can  consummate  such

transactions;

● The Company  has  up  to  $8.5  million  remaining  from  the  FBR  Sales  Agreement  as  of  March  20,  2019  under  the  prospectus  supplement  updated

October 3, 2018; and

● The Company may seek additional capital in the private and/or public equity markets, to continue its operations, respond to competitive pressures,
develop  new  products  and  services,  and  to  support  new  strategic  partnerships.  The  Company  is  evaluating  additional  equity/debt  financing
opportunities on an ongoing basis and may execute them when appropriate. However, there can be no assurances that the Company can consummate
such a transaction, or consummate a transaction at favorable pricing.

Note 2. Summary of Significant Accounting Policies

Principles of Consolidation

The  consolidated  financial  statements  include  Soligenix,  Inc.,  and  its  wholly  and  majority  owned  subsidiaries.  All  significant  intercompany  accounts  and
transactions have been eliminated as a result of consolidation.

F-8

 
 
 
 
 
 
 
 
 
 
Operating Segments

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated on a regular basis by
the  chief  operating  decision  maker,  or  decision  making  group,  in  deciding  how  to  allocate  resources  to  an  individual  segment  and  in  assessing  the
performance of the segment. The Company divides its operations into two operating segments: BioTherapeutics and Vaccines/BioDefense.

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents.

Contracts and Grants Receivable

Contracts and grants receivable consist of amounts due from various grants from the NIH and contracts from NIAID, an institute of NIH, for costs incurred
prior to the period end under reimbursement contracts. The amounts were billed to the respective governmental agencies in the month subsequent to period
end and collected shortly thereafter. Accordingly, no allowance for doubtful amounts has been established. If amounts become uncollectible, they are charged
to operations.

Intangible Assets

One of the most significant estimates or judgments that the Company makes is whether to capitalize or expense patent and license costs. The Company makes
this  judgment  based  on  whether  the  technology  has  alternative  future  uses,  as  defined  in  Financial  Accounting  Standards  Board  (“FASB”)  Accounting
Standards Codification (“ASC”) 730, Research and Development. Based on this consideration, the Company capitalizes payments made to legal firms that are
engaged in filing and protecting rights to intellectual property and rights for its current products in both the domestic and international markets. The Company
believes that patent rights are one of its most valuable assets. Patents and patent applications are a key component of intellectual property, especially in the
early  stage  of  product  development,  as  their  purchase  and  maintenance  gives  the  Company  access  to  key  product  development  rights  from  Soligenix’s
academic and industry partners. These rights can also be sold or sub-licensed as part of its strategy to partner its products at each stage of development as the
intangible assets have alternative future use. The legal costs incurred for these patents consist of work associated with filing new patents designed to protect,
preserve and maintain the Company’s rights, and perhaps extend the lives of the patents. The Company capitalizes such costs and amortizes intangibles on a
straight-line basis over their expected useful life – generally a period of 11 to 16 years.

The Company did not capitalize any patent related costs during the years ended December 31, 2018 or 2017.

These intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable
or if the underlying program is no longer being pursued. If the sum of the expected undiscounted cash flows is less than the carrying value of the related asset
or group of assets, a loss is recognized for the difference between the fair value and carrying value of the related asset or group of assets. No such write downs
have occurred during the years ended December 31, 2018 and 2017.

Impairment of Long-Lived Assets

Office furniture and equipment and intangible assets with finite lives are evaluated and reviewed for impairment whenever events or changes in circumstances
indicate that the carrying amount may not be recoverable. The Company recognizes impairment of long-lived assets in the event the net book value of such
assets exceeds the estimated future undiscounted cash flows attributable to such assets. If the sum of the expected undiscounted cash flows is less than the
carrying value of the related asset or group of assets, a loss is recognized for the difference between the fair value and the carrying value of the related asset or
group of assets. Such analyses necessarily involve significant judgment.

F-9

 
 
 
 
 
 
 
 
 
 
 
 
 
 
The Company did not record any impairment of long-lived assets for the years ended December 31, 2018 or 2017.

Fair Value of Financial Instruments

FASB ASC 820 —  Fair  Value  Measurements  and  Disclosures,  defines  fair  value  as  the  price  that  would  be  received  to  sell  an  asset  or  paid  to  transfer  a
liability  in  an  orderly  transaction  between  market  participants  at  the  measurement  date.  FASB  ASC  820  requires  disclosures  about  the  fair  value  of  all
financial  instruments,  whether  or  not  recognized,  for  financial  statement  purposes.  Disclosures  about  the  fair  value  of  financial  instruments  are  based  on
pertinent information available to the Company on December 31, 2018. Accordingly, the estimates presented in these financial statements are not necessarily
indicative of the amounts that could be realized on disposition of the financial instruments.

FASB ASC  820  specifies  a  hierarchy  of  valuation  techniques  based  on  whether  the  inputs  to  those  valuation  techniques  are  observable  or  unobservable.
Observable  inputs  reflect  market  data  obtained  from  independent  sources,  while  unobservable  inputs  reflect  market  assumptions.  The  hierarchy  gives  the
highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable
inputs (Level 3 measurement).

The three levels of the fair value hierarchy are as follows:

● Level 1 — Quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.
Level 1 primarily consists  of  financial  instruments  whose  value  is  based  on  quoted  market  prices  such  as  exchange-traded instruments and listed
equities.

● Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2
includes financial instruments that are valued using models or other valuation methodologies. These models consider various assumptions, including
volatility  factors,  current  market  prices  and  contractual  prices  for  the  underlying  financial  instruments.  Substantially  all  of  these  assumptions  are
observable in the marketplace, can be derived from observable data or are supported by observable levels at which transactions are executed in the
marketplace.

● Level 3 — Unobservable inputs for the asset or liability. Financial instruments are considered Level 3 when their fair values are determined using

pricing models, discounted cash flows or similar techniques and at least one significant model assumption or input is unobservable.

The carrying amounts reported in the consolidated balance sheet for cash and cash equivalents, contracts and grants receivable, accounts payable, accrued
expenses, and accrued compensation approximate their fair value based on the short-term maturity of these instruments.

Revenue Recognition

The Company’s revenues are primarily generated from government contracts and grants. The revenue from government contracts and grants is based upon
subcontractor costs and internal costs incurred that are specifically covered by the contracts and grants, plus a facilities and administrative rate that provides
funding  for  overhead  expenses  and  management  fees.  These  revenues  are  recognized  when  expenses  have  been  incurred  by  subcontractors  or  when  the
Company incurs reimbursable internal expenses that are related to the government contracts and grants.

Research and Development Costs

Research  and  development  costs  are  charged  to  expense  when  incurred  in  accordance  with  FASB  ASC  730,  Research  and  Development.  Research  and
development  includes  costs  such  as  clinical  trial  expenses,  contracted  research  and  license  agreement  fees  with  no  alternative  future  use,  supplies  and
materials,  salaries,  share-based  compensation,  employee  benefits,  equipment  depreciation  and  allocation  of  various  corporate  costs.  Purchased  in-process
research and development expense represents the value assigned or paid for acquired research and development for which there is no alternative future use as
of the date of acquisition.

F-10

 
 
 
 
 
 
 
 
 
 
 
 
 
Share-Based Compensation

Stock options are issued with an exercise price equal to the market price on the date of grant. Stock options issued to directors upon re-election vest quarterly
for a period of one year (new director issuances are fully vested upon issuance). Stock options issued to employees generally vest 25% on the grant date, then
25%  each  subsequent  year  for  a  period  of  three  years.  These  options  have  a  ten  year  life  for  as  long  as  the  individuals  remain  employees  or  directors.  In
general, when an employee or director terminates their position, the options will expire within three months, unless otherwise extended by the Board.

From time to time, the Company issues restricted shares of common stock to vendors and consultants as compensation for services performed. Typically these
instruments vest upon issuance and therefore the entire share-based compensation expense is recognized upon issuance to the vendors and/or consultants.

Share-based compensation expense for options, warrants and shares of common stock granted to non-employees has been determined in accordance with and
FASB ASC 505-50, Equity-Based Payments to Non-Employees,  and  represents  the  fair  value  of  the  consideration  received,  or  the  fair  value  of  the  equity
instruments issued, whichever may be more reliably measured. For options that vest over future periods, the fair value of options granted to non-employees is
amortized as the options vest. The fair value is remeasured each reporting period until performance is complete.

During the year ended December 31, 2018, the Company issued 370,420 stock options at a weighted average exercise price of $1.14 per share. The fair value
of  options  issued  during  the  years  ended  December  31,  2018  and  2017  was  estimated  using  the  Black-Scholes  option-pricing  model  and  the  following
assumptions:

● a dividend yield of 0%;
● an expected life of 4 years;
● volatility of 91% - 94% for 2018 and 90% - 93% for 2017;
● forfeitures at a rate of 12%; and
● risk-free interest rates ranging from 2.68% to 2.93% in 2018 and 1.60% to 2.02% in 2017.

The fair value of each option grant made during 2018 and 2017 was estimated on the date of each grant using the Black-Scholes option pricing model and
amortized ratably over the option vesting periods, which approximates the service period.

Foreign Currency Transactions and Translation

In 2018, the Company changed the status of a wholly owned subsidiary in the United Kingdom (“UK”) from inactive to active and incurred expenditures in
multiple currencies including the US dollar, the British Pound and the Euro to fund its clinical trial operations in the UK and select countries in Europe. In
accordance with ASC 830 Foreign Currency Matters, the UK subsidiary expresses its US dollar and Euro denominated transactions in its functional currency,
the  British  Pound,  with  related  transaction  gains  or  losses  included  in  net  income.  On  a  quarterly  basis,  the  financial  statements  of  the  UK  subsidiary  are
translated into US dollars and consolidated into the Company’s financials, with related translation adjustments reported as a cumulative translation adjustment
(“CTA”), which is a component of accumulated other comprehensive income. In 2018, the Company recognized foreign currency transaction gains of $437 in
its consolidated statement of operations and a foreign currency translation loss of $3,669 as CTA in its consolidated balance sheet.

Income Taxes

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts
of existing assets and liabilities and their respective tax basis. A valuation allowance is established when it is more likely than not that all or a portion of a
deferred  tax  asset  will  not  be  realized.  A  review  of  all  available  positive  and  negative  evidence  is  considered,  including  the  Company’s  current  and  past
performance,  the  market  environment  in  which  the  Company  operates,  the  utilization  of  past  tax  credits,  and  the  length  of  carryback  and  carryforward
periods.  Deferred  tax  assets  and  liabilities  are  measured  utilizing  tax  rates  expected  to  apply  to  taxable  income  in  the  years  in  which  those  temporary
differences  are  expected  to  be  recovered  or  settled.  No  current  or  deferred  income  taxes  have  been  provided  through  December  31,  2018  due  to  the  net
operating losses incurred by the Company since its inception. The Company recognizes accrued interest and penalties associated with uncertain tax positions,
if  any,  as  part  of  income  tax  expense.  There  were  no  tax  related  interest  and  penalties  recorded  for  2018  and  2017.  Additionally,  the  Company  has  not
recorded an asset for unrecognized tax benefits or a liability for uncertain tax positions at December 31, 2018 and 2017.

Earnings Per Share

Basic earnings per share (“EPS”) excludes dilution and is computed by dividing income (loss) available to common stockholders by the weighted-average
number  of  common  shares  outstanding  for  the  period.  Diluted  EPS  reflects  the  potential  dilution  that  could  occur  if  securities  or  other  contracts  to  issue
common stock were exercised or converted into common stock or resulted in the issuance of common stock that shared in the earnings of the entity. Since
there  is  a  significant  number  of  options  and  warrants  outstanding,  fluctuations  in  the  actual  market  price  can  have  a  variety  of  results  for  each  period
presented.

The following table summarizes potentially dilutive adjustments to the number of common shares which were excluded from the diluted calculation because
their effect would be anti-dilutive due to the losses in each period.

respectively.

Use of Estimates and Assumptions

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and
assumptions such as the fair value of warrants and stock options and the useful life of intangibles that affect the reported amounts in the financial statements
and accompanying notes. Actual results could differ from those estimates.

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, “Leases” (Topic 842). The FASB issued this update to increase transparency and comparability among
organizations  by  requiring  all  leases  with  terms  longer  than  12  months  be  recognized  by  the  lessee  on  its  balance  sheet  as  a  right-of-use  asset  and  a
corresponding lease liability, including leases currently accounted for as operating leases, and disclosing key information about leasing arrangements. The
updated guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption of the
update is permitted. The Company adopted the new standard on January 1, 2019 using a modified retrospective approach. Upon the adoption of this standard,
we recognized right-of-use assets and corresponding operating lease liabilities pertaining to our operating leases on our balance sheets. The adoption of this
standard did not have a material impact on our consolidated financial statements.

The  Company  had  gross  NOLs  at  December  31,  2018  of  approximately  $104,131,000  for  federal  tax  purposes,  approximately  $14,028,000  for  state  tax
purposes  and  approximately  $688,000  for  foreign  tax  purposes.  Portions  of  these  NOLs  will  begin  to  expire  in  2019.  In  addition,  the  Company  has
$8,333,000 of various tax credits which expire from 2019 to 2037. The Company may be able to utilize its NOLs to reduce future federal and state income tax
liabilities. However, these NOLs are subject to various limitations under Internal Revenue Code (“IRC”) Section 382. IRC Section 382 limits the use of NOLs
to the extent there has been an ownership change of more than 50 percentage points. In addition, the NOL carry forwards are subject to examination by the
taxing authority and could be adjusted or disallowed due to such exams. Although the Company has not undergone an IRC Section 382 analysis, it is likely
that the utilization of the NOLs may be substantially limited.

The Company and one or more of its subsidiaries files income tax returns in the U.S. Federal jurisdiction, and various state and local jurisdictions. During the
year  ended  December  31,  2017,  in  accordance  with  the  State  of  New  Jersey’s  Technology  Business Tax  Certificate  Program,  which  allowed  certain  high
technology and biotechnology companies to sell unused NOL carry forwards to other New Jersey-based corporate taxpayers, the Company sold New Jersey
NOL carry forwards, resulting in the recognition of $416,810 of income tax benefit, net of transaction costs. The Company has not yet sold its 2017 New
Jersey NOLs but may be able to do so in the future. There can be no assurance as to the continuation or magnitude of this program in the future.

Reconciliations of the difference between income tax benefit computed at the federal and state statutory tax rates and the provision for income tax benefit for
the years ended December 31, 2018 and 2017 were as follows:

Federal tax at statutory rate
State tax benefits, plus sale of NJ NOL, net of federal benefit
Foreign tax rate difference
Permanent differences
Orphan drug and research and development credits
Change in statutory rate

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The
Tax  Act  significantly  revises  U.S.  corporate  income  taxation  by,  among  other  things,  lowering  the  U.S.  corporate  income  tax  rate  from  35.0  %  to  21.0%
effective January 1, 2018. Tax Reform did not have any impact to the tax provision due to the full valuation allowance on its deferred tax assets and the most
significant impact on its consolidated financial statements was the reduction of approximately $14 million for the deferred tax assets related to net operating
losses and other assets recorded in the 2017 financial statements. Such reduction is fully offset by changes to the Company’s valuation allowance.

Lincoln Park Equity Line

In March 2016, the Company entered into a common stock purchase agreement with Lincoln Park. The Lincoln Park equity facility allows the Company to
require Lincoln Park to purchase up to 10,000 shares (“Regular Purchase”) of the Company’s common stock every two business days, up to an aggregate of
$12.0  million  over  approximately  a  36-month  period  with  such  amounts  increasing  as  the  quoted  stock  price  increases.  The  Regular  Purchase  may  be
increased up to 15,000 shares of common stock if the closing price of the common shares is not below $10.00, up to 20,000 shares of common stock if the
closing price of the common shares is not below $15.00 and up to 25,000 shares of common stock if the closing price of the common shares is not below
$20.00. The purchase price for the Regular Purchase shall be equal to the lesser of (i) the lowest sale price of the common shares during the purchase date, or
(ii)  the  average  of  the  three  lowest  closing  sale  prices  of  the  common  shares  during  the  twelve  business  days  prior  to  the  purchase  date.  Each  Regular
Purchase shall not exceed $750,000. Furthermore, for each purchase by Lincoln Park, additional commitment shares in commensurate amounts up to a total
of 50,000 shares will be issued based upon the relative proportion of the aggregate amount of $12.0 million. In addition to the Regular Purchase and provided
that the closing price of the common shares is not below $7.50 on the purchase date, the Company in its sole discretion may direct Lincoln Park on each
purchase date to purchase on the next stock trading day (“Accelerated Purchase Date”) additional shares of Company stock up to the lesser of (i) three times
the number of shares purchased following a Regular Purchase or (ii) 30% of the trading volume of shares traded on the Accelerated Purchase Date at a price
equal to the lesser of the closing sale price on the Accelerated Purchase Date or 95% of the Accelerated Purchase Date’s volume weighted average price. As
of December 31, 2018, the Company had $10.1 million available under the equity facility. The common stock purchase agreement with Lincoln Park will
expire on March 31, 2019, and any issuable amounts of common stock remaining at the expiration date will be forfeited.

FBR At Market Issuance Sales Agreement

On August 11, 2017, the Company entered into the FBR Sales Agreement to sell shares of the Company’s common stock from time to time, through an “at-
the-market” equity offering program under which FBR acts as sales agent. Under the FBR Sales Agreement, the Company sets the parameters for the sale of
shares, including the number of shares to be issued, the time period during which sales may be requested to be made, limitation on the number of shares that
may be sold in any one trading day and any minimum price below which sales may not be made. The FBR Sales Agreement provides that FBR is entitled to
compensation for its services in an amount equal to 3% of the gross proceeds from the sale of shares sold under the FBR Sale Agreement. The Company has
no obligation to sell any shares under the FBR Sales Agreement, and may suspend solicitation and offers under the FBR Sales Agreement at any time.

Sales of common stock made pursuant to the FBR Sales Agreement, if any, will be made pursuant to the Company’s effective shelf registration statement on
Form  S-3  (File  No.  333-217738)  filed  on  May  5,  2017  with  the  SEC,  the  base  prospectus  filed  as  part  of  such  registration  statement,  and  any  prospectus
supplements. The shares sold pursuant to the FBR Sales Agreement have been and will be issued pursuant to General Instruction I.B.6 of Form S-3, which
permits the Company to sell shelf securities in a public primary offering with a value not exceeding one-third of the average market value of the Company’s
voting and non-voting common equity held by non-affiliates in any 12-month period as long as the aggregate market value of the Company’s outstanding
voting and non-voting common equity held by non-affiliates is less than $75 million.

On August 11, 2017, the Company filed a prospectus supplement for the sale of up to $4.8 million of shares of common stock pursuant to the FBR Sales
Agreement, and the Company sold an aggregate of approximately $1 million of shares thereunder. The offering costs incurred to register the shares pursuant
to the prospectus supplement dated August 11, 2017 were $164,825. On October 3, 2018, the Company filed an updated prospectus supplement with the SEC
and may offer and sell shares of the Company’s common stock pursuant to the FBR Sales Agreement having an aggregate offering price of up to $9.0 million,
from  time  to  time.  The  prospectus  supplement  filed  on  October  3,  2018,  supersedes  the  prospectus  supplement  dated  August  11,  2017,  and  no  additional
shares will be offered or sold pursuant to the prospectus supplement dated August 11, 2017. As of March 20, 2019, there was $8.5 million available for the
sale of common stock under the FBR Sales Agreement.

Note 10. Concentrations

At  December  31,  2018  and  2017,  the  Company  had  deposits  in  major  financial  institutions  that  exceeded  the  amount  under  protection  by  the  Securities
Investor Protection Corporation (“SIPC”). Currently, the Company is covered up to $1,000,000 by the SIPC and at times maintains cash balances in excess of
the SIPC coverage.

Note 11. Commitments and Contingencies

The  Company  has  commitments  of  approximately  $500,000  at  December  31,  2018  for  several  licensing  agreements  with  consultants  and  universities.
Additionally,  the  Company  has  collaboration  and  license  agreements,  which  upon  clinical  or  commercialization  success,  may  require  the  payment  of
milestones of up to $7.9 million and/or royalties up to 6% of net sales of covered products, if and when achieved. However, there can be no assurance that
clinical or commercialization success will occur. In June 2018, the Company paid approximately $197,000 in milestone payments.

The Company currently leases approximately 6,200 square feet of office space at 29 Emmons Drive, Suite B-10 in Princeton, New Jersey pursuant to a lease
that was amended in October 2017 and expires in October 2020. This office space currently serves as the Company’s corporate headquarters. The rent for the
first 12 months was approximately $11,367 per month, or approximately $22.00 per square foot. The rent increased to approximately $11,625 per month, or
approximately  $22.50  per  square  foot,  for  the  12  months  beginning  November  1,  2018  and  will  increase  beginning  November  1,  2019  to  approximately
$11,883 per month, or approximately $23.00 per square foot for the remainder of the lease.

On September 3, 2014, the Company entered into an asset purchase agreement with Hy Biopharma, Inc. (“Hy Biopharma”) pursuant to which the Company
acquired  certain  intangible  assets,  properties  and  rights  of  Hy  Biopharma  related  to  the  development  of  Hy  BioPharma’s  synthetic  hypericin  product.  As
consideration  for  the  assets  acquired,  the  Company  paid  $275,000  in  cash  and  issued  184,912  shares  of  common  stock  with  a  fair  value  based  on  the
Company’s stock price on the date of grant of $3,750,000. These amounts were charged to research and development expense during the third quarter of 2014
as  the  assets  will  be  used  in  the  Company’s  research  and  development  activities  and  do  not  have  alternative  future  use  pursuant  to  generally  accepted
accounting  principles  in  the  United  States.  Provided  all  future  success-oriented  milestones  are  attained,  the  Company  will  be  required  to  make  additional
payments of up to $10.0 million, if and when achieved. Payments will be payable in restricted securities of the Company provided they do not exceed 19.9%
ownership of the Company’s outstanding stock. As of December 31, 2018, no milestone or royalty payments have been paid or accrued.

In February 2007, the Company’s Board of Directors authorized the issuance of 5,000 shares of the Company’s common stock to Dr. Schaber immediately
prior to the completion of a transaction, or series or a combination of related transactions, negotiated by its Board of Directors whereby, directly or indirectly,
a majority of its capital stock or a majority of its assets are transferred from the Company and/or its stockholders to a third party. Dr. Schaber’s amended
employment agreement includes the Company’s obligation to issue such shares if such event occurs.

As a result of the above agreements, the Company has future contractual obligations over the next five years as follows:

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Soligenix, Inc. and Subsidiaries (the “Company”) as of December 31, 2018 and 2017, and
the related consolidated statements of operations, comprehensive loss, shareholders’ equity, and cash flows for each of the years then ended and the related

financial position of the Company as of December 31, 2018 and 2017, and the consolidated results of their operations and their cash flows for each of the
years then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

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

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

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

This First Amendment to Employment Agreement (the “Amendment”) is made and entered into as of March 26, 2019 to be effective as of April 1,
2019  by  and  between  Soligenix,  Inc.,  a  Delaware  corporation  having  a  place  of  business  at  29  Emmons  Drive,  Suite  B-10,  Princeton,  NJ  08540  (the
“Corporation”), and Richard Straube, MD, an individual (the “Employee”).

W I T N E S S E T H:

WHEREAS,  the  Corporation  and  Employee  entered  into  that  certain  Employment  Agreement  dated  January  6,  2014  (the  “Employment

Agreement”), pursuant to which the Corporation employed Employee as Senior Vice President and Chief Medical Officer; and

WHEREAS, the Corporation and Employee desire to amend the Employment Agreement in accordance with the terms thereof and upon the terms

set forth herein.

NOW, THEREFORE, in consideration of the foregoing and the mutual promises and covenants herein contained, it is agreed as follows:

I.                   AMENDMENT OF EMPLOYMENT AGREEMENT

A.                Section 1 of the Employment Agreement is hereby amended and restated in its entirety as follows:

1.       EMPLOYMENT DUTIES

The Corporation engages and employs Employee, and Employee hereby accepts engagement and employment, as Senior Vice President and
Chief Medical Officer reporting to the Chief Executive Officer of the Corporation, and shall perform high quality service to the Corporation
to direct, supervise and have responsibility for the clinical development efforts of the Corporation, including, but not limited to: (i) directing
the clinical research and regulatory strategies of the Corporation; (ii) supporting the clinical development personnel of the Corporation; and
(iii) medical monitoring of the Corporation’s ongoing and planned clinical trials and such other activities as may be reasonably requested by
the Chief Executive Officer or the Board of Directors of the Corporation. Employee acknowledges and understands that his employment
may entail travel on behalf of the Corporation. Employee shall devote at least 20 hours per week to the performance of his duties hereunder.

B.                 Section 3(a) of the Employment Agreement is hereby amended and restated in its entirety as follows:

(a) (i) The Corporation shall pay Employee an annual base salary (“Base Salary”) of one hundred and seventy thousand

dollars ($170,000) per annum, payable in accordance with the usual payroll period of the Corporation.

(ii) The Corporation may pay Employee a discretionary annual bonus. The determination whether to pay and the amount

of such bonus shall be made upon the recommendation of the Chief Executive Officer and by the approval of the Board of Directors.

C.                 Section 3(e) of the Employment Agreement is hereby amended and restated in its entirety as follows:

(e)              During  the  Term,  Employee  shall  be  entitled  up  to  a  maximum  of  five  (5)  paid  personal  days  consistent  with

corporate policy.

Section 3(f) of the Employment Agreement is hereby deleted its entirety.

1 

 
 
D.                Section 7(b) of the Employment Agreement is hereby amended and restated in its entirety as follows:

(b)              Upon  termination  by  the  Corporation  pursuant  to  either  subparagraph  (i)  or  (iii)  of  paragraph  (a)  above  or  by
Employee other than pursuant to subparagraph (iv) of paragraph (a) above, the Employee (or his estate in the event of termination pursuant
to subparagraph (i)) shall be entitled to receive the Base Salary unpaid as of the date of termination including any personal days not taken.

E.                 Section 7(c) of the Employment Agreement is hereby amended and restated in its entirety as follows:

(c)       Upon termination by the Corporation without Just Cause or pursuant to subparagraphs (i), (ii) or (iv) of paragraph
(a) above, then the term of the Agreement as set forth in Section 2 hereof shall be deemed to have been terminated as of such date and the
Corporation shall pay to the Employee (or his estate in the event of termination pursuant to subparagraph (i)), (A) Base Salary unpaid as of
the date of termination, including any personal days not taken, (B) severance equal to his annual rate of Base Salary in effect as of the date
of  termination  payable  at  said  rate  in  accordance  with  the  Corporation’s  payroll  practices  for  a  one  month  period  (subject  to  set-off)
(“Severance  Pay”).  Notwithstanding  anything  herein  to  the  contrary,  the  Employee  shall  not  be  entitled  to  the  Severance  Pay  unless  he
executes and delivers to the Corporation a general release of claims in such form as determined by the Corporation (the “Release”) and such
Release  becomes  effective  and  irrevocable  within  sixty  (60)  days  following  the  date  of  termination  or  resignation.  Any  Severance  Pay
required  under  this  Section  7(c)  shall  commence  on  the  first  payroll  date  coincident  or  immediately  following  the  sixtieth  (60th)  day
following the Employee’s date of termination. Notwithstanding anything herein to the contrary, each payment of Severance Pay shall be
deemed to be a separate payment within the meaning of Section 409A of the Code and the regulations thereunder. Health benefits will also
be  maintained  for  Employee  (or  his  dependents  in  the  event  of  termination  pursuant  to  subparagraph  (i))  by  Company  during  severance
period. No unvested options shall vest beyond the termination date, except where previously noted in Section 3(b) or at the discretion of the
Stock Option Plan Administrator. For purposes of payments under this Agreement that are subject to (and not exempt from) Section 409A
of the Code that are payable upon the Employee’s “termination of employment,” such term shall instead mean “separation from service”
within the meaning of Section 409A and the Treasury Regulations promulgated thereunder.

II.                OTHER PROVISIONS INCORPORATED AND UNCHANGED

All other provisions of the Employment Agreement are incorporated herein and shall remain in full force and effect.

III.             EFFECT OF AMENDMENT

The amendments to the Employment Agreement made hereby shall be effective as of the date hereof and on a prospective basis only.

IV.             ENTIRE AGREEMENT MODIFICATION

The Employment Agreement, as amended hereby, contains the entire agreement of the parties relating to the subject matter hereof, and the parties
hereto have made no agreements, representations or warranties relating to the subject matter hereof which are not set forth herein. No modification hereof
shall be valid unless made in writing and signed by the parties hereto.

V.                GOVERNING LAW

This  Amendment  shall  be  governed  by,  and  construed  and  interpreted  in  accordance  with,  the  laws  of  the  State  of  New  Jersey  without  regard  to

principles of conflict of laws.

VI.             COUNTERPARTS

This Amendment may be executed in any number of counterparts by the parties on separate counterparts, each of which shall, when executed and
delivered, constitute an original of this Amendment, but all of which shall together constitute one and the same instrument. Counterparts may be delivered via
facsimile,  electronic  mail  (including  pdf  or  any  other  electronic  signature,  e.g.,  www.docusign.com)  or  other  transmission  method  and  any  counterpart  so
delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.
