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 first-in-class photodynamic therapy (SGX301) utilizing topical synthetic hypericin activated with safe
visible light for the treatment of cutaneous T-cell lymphoma (“CTCL”), 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), and our novel innate defense regulator (“IDR”) technology, dusquetide (SGX942) for the treatment of oral mucositis in head
and neck cancer.

Our Vaccines/BioDefense business segment includes active development programs for RiVax™, our ricin toxin vaccine candidate, OrbeShield®, our GI acute
radiation  syndrome  (“GI  ARS”)  therapeutic  candidate  and  SGX943,  our  melioidosis  therapeutic  candidate.  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.  We  plan  to  use  the  funds  received  under  our  government  contracts  with  the  Biomedical  Advanced  Research  and
Development Authority (“BARDA”) and NIAID to advance the development of OrbeShield® for the treatment of GI ARS.

An outline for our business strategy follows:

● Complete enrollment and report preliminary results in our pivotal Phase 3 clinical trial of SGX301 for the treatment of CTCL;
● Initiate a Phase 3 clinical trial of SGX203, for the treatment of pediatric Crohn’s disease;
● Continue to collect the long-term follow-up safety data from the SGX942 Phase 2 proof-of-concept study in the treatment of oral mucositis in head and

neck cancer patients and publish the findings from this study;

● Obtain FDA agreement on a pivotal Phase 2b/3 protocol of SGX942 in the treatment of oral mucositis in head and neck cancer patients;
● Continue development of RiVax™ in combination with our ThermoVax® technology, to develop new heat stable vaccines in biodefense and infectious

diseases with the potential to collaborate and/or partner with other companies in these areas;

● Advance the preclinical and manufacturing development of OrbeShield® as a biodefense medical countermeasure for the treatment of GI ARS;
● Continue  to  apply  for  and  secure  additional  government  funding  for  each  of  our  BioTherapeutics  and  Vaccines/BioDefense  programs  through  grants,

contracts and/or procurements;

● Acquire or in-license new clinical-stage compounds for development; and
● Explore other business development and merger/acquisition strategies.

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 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 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  improvement  with
topical hypericin treatment 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 United States Food and Drug Administration (the “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  also  was  granted  orphan  drug  designation  from  the
European Medicines Agency Committee for Orphan Medical Products.

We initiated our pivotal Phase 3 clinical study of SGX301 in the treatment of CTCL during December 2015 and anticipate data in the second half of 2016.

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 than those with MF.

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.

SGX94

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

SGX94  is  based  on  a  new  class  of  short,  synthetic  peptides  known  as  IDRs  that  have  a  novel  mechanism  of  action  in  that  it  is  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.

SGX94 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. SGX94 was shown to be safe and well-tolerated in all dose groups when administered by IV over 7 days and was consistent with safety results
seen in pre-clinical studies. SGX94 is the subject of an open Investigational New Drug (“IND”) application which has been cleared by the FDA. We believe
that  market  opportunities  for  SGX94  include  mucositis,  acute  methicillin  resistant  Staphylococcus  aureus  (MRSA)  bacterial  infections,  acinetobacter,
melioidosis, acute radiation syndrome and as a vaccine adjuvant, with potential opportunities for non-dilutive funding to support the development.

SGX942 – for Treating Oral Mucositis in Head and Neck Cancer

SGX942 is our product candidate containing our IDR technology platform, SGX94, 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.

6

 
 
 
 
 
 
 
 
 
 
 
  
We initiated a Phase 2 clinical study of SGX942 in the treatment of oral mucositis in head and neck cancer patients in the second half 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  (CRT)  for
treatment of their head and neck cancer. In addition to identifying the optimal dose of 1.5 mg/kg, this study achieved all objectives, including a trend towards
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 significant decreases in infection rate were also observed with SGX942 treatment, consistent with the preclinical results observed in animal
models, and are being further evaluated. 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. Long-term follow-up evaluations are ongoing with final results expected in the fourth quarter of 2016. Data
from this Phase 2 trial is expected to be submitted for future presentation and publication.

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 recently 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.

7

 
 
 
 
 
 
 
 
 
 
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 in 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.

We are pursuing orphan drug designations for relevant indications as appropriate in both the U.S. and Europe. An orphan drug designation provides for seven
years and ten years of market exclusivity upon approval in the U.S. and Europe, respectively.

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 anticipate initiating a Phase 3 clinical study of SGX203 in the treatment of pediatric Crohn’s disease in the second half of 2016.

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.

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 recent published historical control data in this patient population.
This program was supported in part by a $500,000 two-year Small Business Innovation and Research (“SBIR”) grant awarded by the National Institutes of
Health (“NIH”). We are currently working with our Radiation Enteritis medical advisory board in pursuing additional funding from the NIH to support the
clinical development program.

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

We estimate the potential worldwide market for oral BDP is in excess of $500 million for all applications, including the treatment of acute radiation enteritis.
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.

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 B 12 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

Our 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 companies of 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. We believe that the savings realized from the elimination of cold chain costs and related product losses would significantly increase
the profitability of vaccine products. We believe that elimination of the cold chain could further facilitate the use of these vaccines in the lesser developed
parts of the world. ThermoVax® has the potential to facilitate easier storage and distribution of strategic national stockpile vaccines 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  have  also
demonstrated the compatibility of our thermostabilization technology with other secondary adjuvants such as TLR-4 agonists. Additionally, the University of
Colorado conducted a study that demonstrated a heat stable vaccine formulation of a human papillomavirus (HPV) vaccine.  The work was conducted by Drs.
Randolph and Garcea and demonstrated the successful conversion of a commercial virus-like particle (VLP) based vaccine requiring cold chain storage to a
subunit, alum-adjuvanted, vaccine which is stable at ambient temperatures.  This work, funded by a University of Colorado Seed grant and the Specialized
Program of Research Excellence (SPORE) in cervical cancer, is the first demonstration of the utility of ThermoVax® technology for the development of a
subunit based commercial vaccine.  The HPV vaccine formulation was found to be stable for at least 12 weeks at 50 degrees C.  In the study, mice immunized
with the ThermoVax®-stabilized HPV subunit vaccine were also found to achieve immune responses similar to the commercial HPV vaccine, Cervarix®, as
measured by either total antibody levels or neutralizing antibody levels.  Moreover, whereas the immune responses to Cervarix® were reduced after storage
for  12  weeks  at  50  degrees  C,  the  ThermoVax®  formulated  vaccine  retained  its  efficacy.  The  results  were  published  online  in  the  European  Journal  of
Pharmaceutics and Biopharmaceutic. See http://www.sciencedirect.com/science/article/pii/S0939641115002416).

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 Mānoa 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.

We  intend  to  seek  out  potential  partnerships  with  companies  marketing  FDA/ex-U.S.  health  authority  approved  Alum  adjuvanted  vaccines  and  currently
developing  Alum  adjuvanted  vaccines  that  are  interested  in  eliminating  the  need  for  cold  chain  for  their  products.  We  believe  that  ThermoVax®  also  will
enable  us  to  expand  our  vaccine  development  expertise  beyond  biodefense  into  the  infectious  disease  space  and  also  has  the  potential  to  allow  for  the
development of multivalent vaccines (e.g., combination ricin-anthrax vaccine).

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 subunit ricin A chain that is enzymatically inactive and lacks residual toxicity of the holotoxin. RiVax™ has
demonstrated  statistically  significant  (p  <  0.0001)  preclinical  survival  results  in  a  lethal  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
March 24, 2015), 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  completed  in  September  2012,  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. 10:1697-9). We have
adapted the original manufacturing process for the immunogen contained in RiVax™ for large scale manufacturing and are further establishing correlates of
the human immune response in non-human primates. We have initiated a development agreement with Emergent BioSolutions to implement a commercially
viable, scalable production technology for the RiVax™ drug substance protein antigen.

10

 
 
 
 
 
 
 
The development of RiVax™ has been sponsored through a series of overlapping challenge grants, UC1, and cooperative grants, U01, from the NIH, granted
to Soligenix 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.

RiVax™ has been granted orphan drug designation by the FDA for the prevention of ricin intoxication.

Assuming development efforts are successful for RiVax™, we believe potential government procurement contract(s) could reach $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.

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 Investigations
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. As recently as April 2013, letters addressed to the President, a U.S. Senator and a
judge tested positive for ricin.

The Center for Disease Control 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.

11

 
 
 
 
 
 
 
 
 
 
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 of BARDA for ARS and other medical
countermeasure indications. The FDA has cleared the IND application for OrbeShield® for the mitigation of morbidity and mortality associated with GI ARS.

In  September  2013,  we  received  two  government  contracts  from  BARDA  and  NIAID  for  the  advanced  preclinical  and  manufacturing  development  of
OrbeShield®  leading  to  FDA  approval  to  treat  GI  ARS.  The  BARDA  contract  contains  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 consists 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. Previously, development of OrbeShield® had been largely supported by a $1 million NIH grant to
Soligenix’s 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 Melioidosis

SGX943 uses the same active ingredient as SGX94 and is being developed in preclinical studies as a potential treatment for melioidosis. Because SGX943
directly  targets  the  innate  immune  system  (and  does  not  attempt  to  kill  the  bacteria  directly),  we  believe  it  is  particularly  relevant  for  antibiotic-resistant
bacteria. The bacteria which causes melioidosis, Burkholderia pseudomallei, is known to be resistant to most antibiotics and to require prolonged treatment
with  the  few  antibiotics  that  do  work.  In  February  2014,  we  were  awarded  a  one-year  NIAID  SBIR  award  of  approximately  $300,000  to  further  evaluate
SGX943 as a potential treatment for melioidosis. Preclinical results to date have demonstrated that SGX943 treatment, in combination with standard of care
antibiotics such as doxycycline, can statistically significantly enhance survival in a lethal murine pneumonic melioidosis model (p< 0.001).

12

 
 
 
 
 
 
 
 
 
 
Melioidosis

Melioidosis is a potentially fatal infection caused by the Gram-negative bacillus, Burkholderia pseudomallei (“Bp”). Highly resistant to many antibiotics, Bp
can cause an acute disease characterized by a fulminant pneumonia and a chronic condition that can recrudesce. There is no preventive vaccine or effective
immunotherapy for melioidosis. We believe that there is an unmet medical need for improved prevention and therapy.

Bp infection (melioidosis) is a major public health concern in the endemic regions of Southeast Asia and Northern Australia. In Northeast Thailand, which
has the highest incidence of melioidosis, the mortality rate associated with Bp infection is over 40 percent, making it the third most common cause of death
from infectious disease in that region after HIV/AIDS and tuberculosis. Bp activity is seen in Southeast Asia, South America, Africa, the Middle East, India,
and Australia. The highest pockets of disease activity occur in Northern Australia and Northeast Thailand with increasing recognition of disease activity in
coastal regions of India.

Beyond its public health significance, Bp and the closely-related Burkholderia mallei (“Bm”) are considered possible biological warfare agents by the DHHS
because of the potential for widespread dissemination through aerosol. Bp like its relative Bm, the cause of Glanders, was studied by the U.S. as a potential
biological warfare agent, but was never weaponized. It has been reported that the Soviet Union was also experimenting with Bp as a biological warfare agent.
 Both Bp and Bm have been designated high priority threats by the DHHS in its PHEMCE Strategy released in 2012 and are classified as Category B Priority
Pathogens by NIAID.

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, or 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, or 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.

13

 
 
 
 
 
 
 
 
 
 
With certain exceptions, once successful clinical testing is completed, the sponsor can submit a New Drug Application, or NDA, for approval of a drug, or a
Biologic License Application, or 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 the Company 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, the
Company 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 the Company 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.

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, or 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.

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 US 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, or HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or
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.

16

 
 
 
 
 
 
 
 
 
 
 
All of the current agreements for the supply 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.  (“Sigma-Tau”).  The  amendment  requires  us  to  make  certain  approval  and  commercialization
milestone payments to Sigma-Tau which could reach up to $6 million. In addition, the Company has agreed to pay Sigma-Tau: (a) a royalty amount equal to
3% of all net sales of oral BDP made directly by the Company, 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  the  Company’s  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  the  Company  and/or  a  potential  partner  from  the
Company’s 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.

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. Two are targeted
therapies (Targretin®-caps and Ontak®), 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, photo 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 effects. There are other drugs currently in development that may have the
potential to be used in early stage (I-IIA) CTCL – one in phase 2 (vorinostat) and others in phase 1. Vorinostat has been approved by the FDA to treat CTCL
patients who have conditions that are unresponsive to other therapies. It currently is being studied in a phase 2 trial for the treatment of all stages of CTCL,
with an estimated completion date for the phase 2 trial in September 2016.

SGX94/942 Competition

Because  SGX94  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 – one
in Phase 3 (under development by Daewoong Pharmaceutical Co., Ltd), four in Phase 2 (under development by Cellceutix Corporation, BioAlliance Pharma
S.A.,  Onexeo,  and  Alder  Biopharmaceuticals  Inc.)  and  one  in  Phase  1  (under  development  by  ActoGenix  N.V.).  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.

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.
There  is  one  other  marketed  biologic,  Tysabri  (natalizumab),  in  a  Phase  2  study  for  pediatric  Crohn’s.  Entocort  (enteric-coated  budesonide)  also  has
completed Phase 3 trials in pediatric Crohn’s disease.

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.

In the area of radiation-protective antidotes such as OrbeShield®, various companies, such as Cleveland Biolabs, 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,  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.

We have issued U.S. patents 8,263,582 and 6,096,731 that cover the use of oral BDP for treating inflammatory disorders of the gastrointestinal tract and the
prevention  and  treatment  of  GI  GVHD,  respectively.  U.S.  patent  numbers  8,263,582  and  6,096,731  are  expected  to  expire  in  March  2022  and  June  2018,
respectively.  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 corresponding European patent application number 09836727.9 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, India, Japan, South Korea and New Zealand.

19

 
 
 
 
 
 
 
 
 
 
 
 
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 University of Colorado
(“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 December 2031.

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 October 2020.

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 US and abroad.
SGX94 was developed pursuant to discoveries made by Professors B. Brett Finlay and Robert Hancock of UBC.  U.S. patent 8,124,721 is expected to expire
in April 2028.

In  2014,  we  acquired  a  novel,  first-in-class,  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 June 2032.

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. 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.

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. The Company has 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, the Company 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 $400,000 upon approval by the FDA of the Company’s 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 the Company sublicenses its rights under the license agreement, the Company will be required to pay Dr. McDonald 10% of
any sublicense fees and royalty payments paid by the sublicense to the Company.

20

 
 
 
 
 
 
 
 
 
 
The term of the license agreement expires upon the expiration of the licensed patent applications or patents. After seven years from the date of the agreement,
Dr. McDonald has the right to terminate the license agreement in its entirety or to terminate exclusivity under the agreement if the Company or its sublicense
has not commercialized or are not actively attempting to commercialize a covered product.

Additionally,  the  agreement  terminates:  (i)  automatically  upon  the  Company  becoming  insolvent;  (ii)  upon  30  days’  notice,  if  the  Company  breaches  any
obligation under the agreement without curing such breach during the notice period; and (iii) upon 90 days’ notice by the Company. After any termination,
the Company will have the right to sell its 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.

SGX94 License Agreements

On December 18, 2012, we announced the acquisition of a novel drug technology, known as SGX94, 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, Soligenix 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.

ThermoVax® License Agreement

On September 1, 2009, we executed a worldwide exclusive option to license patent applications 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 Soligenix 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,  Soligenix  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.”

RiVax™ License Agreement

In January 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™.

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, first-in-class, 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 (b) 20% of all payments, not based on net sales, received by us from our sublicensees. The exclusive license includes rights to several issued
US 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,  properties  and  rights  pursuant  to  an  asset  purchase  agreement  with  Hy
Biopharma Inc. (“Hy Biopharma”). As consideration for the assets acquired, we paid $250,000 in cash and issued 1,849,113 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 common stock of the Company.

Research and Development Expenditure

We  spent  approximately  $5.4  million  and  $9.1  million  in  the  years  ended  December  31,  2015  and  2014,  respectively,  on  research  and  development.  The
amounts we spent on research and development per product during the years ended December 31, 2015, and 2014 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, 2015, we had 16 full-time employees, 8 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, 2015, had an accumulated deficit of approximately $146.9 million. We expect to
incur additional operating losses in the future and expect our cumulative losses to increase. As of December 31, 2015, we had approximately $4.9 million in
cash available. Based on our projected budgetary needs, funding from existing contracts and grants over the next two years and sales to the purchasers under
our existing equity lines, we expect to be able to maintain the current level of our operations for at least the next 12 months.

22

 
 
 
 
 
 
 
 
 
 
 
 
 
 
We  have  sufficient  funds  through  our  existing  biodefense  grant  facilities  from  the  NIAID,  a  division  of  the  NIH,  and  BARDA  to  finance  our  biodefense
projects for the next six years. In September 2014, we entered into a contract with the NIH for the development of RiVaxTM to protect against exposure to
ricin toxin that would provide up to $24.7 million of funding in the aggregate if options to extend the contract are exercised by the NIH. In September 2013,
we entered into contracts with the NIH 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. In September 2009, we received a NIAID grant for approximately $9.4 million for
the development of our biodefense programs. In July 2012, we received an additional SBIR grant from NIAID for $600,000 and in February 2014, we were
awarded a one-year NIAID SBIR grant award of approximately $300,000 to further evaluate SGX943 as a treatment for melioidosis. 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 2015, we have approximately $43.0 million in active contract funding.

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 2015, we have expended approximately $66.2 million developing our current product candidates
for pre-clinical research and development and clinical trials, and we currently expect to spend at least $12.9 million over the next 12 months in connection
with the development of our therapeutic and vaccine products, licenses, employment agreements, and consulting agreements of which approximately $7.6
million will be reimbursed through our existing government contracts and grants. 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 early 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.

23

 
 
 
 
 
 
 
 
 
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 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 (“CMOs”) 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;
● 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  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.

24

 
 
 
 
 
 
 
 
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.

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 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. 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.

25

 
 
 
 
 
 
 
 
 
Additionally, few facilities in the United States and internationally have the capability to test animals with anthrax or 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 documents and other regulations. We can provide no assurance that we will receive or continue to receive funding for
grants 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.

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.

26

 
 
 
 
 
 
 
 
 
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.

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  or  device  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.

27

 
 
 
 
 
 
 
 
 
 
 
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.

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.

Recent 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;
● 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.

28

 
 
 
 
 
 
 
 
 
 
 
 
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.

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.

In addition, 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,  the  University  of  Colorado,  and  George  B.  McDonald,  MD  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.

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.

29

 
 
 
 
 
 
 
 
 
 
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 may 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.

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.

30

 
 
 
 
 
 
 
 
 
 
 
 
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.

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 19 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.

31

 
 
 
 
 
 
 
 
 
 
 
 
 
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.

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 recently 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.

32

 
 
 
 
 
 
 
 
 
 
 
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.

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 Common Stock 

Our common stock price is highly volatile.

The  market  price  of  our  common  stock,  like  that  of  many  other  research  and  development  public  pharmaceutical  and  biotechnology  companies,  has  been
highly volatile and may continue to be so 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;

● 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;
● our available working capital;
● economic and other external factors; and
● general market conditions.

Since January 1, 2015, the closing stock price of our common stock has fluctuated between a high of $2.50 per share to a low of $0.52 per share. On March
18, 2016, the last quoted sale price of our common stock as reported on the OTCQB was $0.82 per share. The fluctuation in the price of our common stock
has sometimes been unrelated or disproportionate to our operating performance. In addition, potential dilutive effects of future sales of shares of common
stock by the Company, 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.

Our common stock trades on the Over-the-Counter Bulletin Board.

Our common stock trades on the OTCQB securities market under the symbol “SNGX.” The OTCQB is a decentralized market regulated by the Financial
Industry  Regulatory  Authority  in  which  securities  are  traded  via  an  electronic  quotation  system  that  serves  more  than  3,000  companies,  but  provides
significantly less liquidity than national market systems such as the NYSE MKT. On the OTCQB, securities are traded by a network of brokers or dealers
who carry inventories of securities to facilitate the buy and sell orders of investors, rather than providing the order matchmaking service seen in specialist
exchanges. OTCQB securities include national, regional, and foreign equity issues. Companies traded on the OTCQB must be current in their reports filed
with the SEC and other regulatory authorities.

Since our common stock is not listed on a national exchange or market, the trading market for our common stock may become illiquid. Our common stock is
subject to the penny stock rules of the SEC, which generally are applicable to equity securities with a price of less than $5.00 per share, other than securities
registered  on  certain  national  securities  exchanges  provided  that  current  price  and  volume  information  with  respect  to  transactions  in  such  securities  is
provided by the exchange or system. The penny stock rules require a broker-dealer, before a transaction in a penny stock not otherwise exempt from the rules,
to deliver a standardized risk disclosure document prepared by the SEC that provides information about penny stocks and the nature and level of risks in the
penny stock market. The broker-dealer also must provide the customer with bid and ask quotations for the penny stock, the compensation of the broker-dealer
and  its  salesperson  in  the  transaction  and  monthly  account  statements  showing  the  market  value  of  each  penny  stock  held  in  the  customer’s  account.  In
addition, the penny stock rules require that, before a transaction in a penny stock that is not otherwise exempt from such rules, the broker-dealer must make a
special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser’s written agreement to the transaction.
As a result of these requirements, our common stock could be priced at a lower price and our stockholders could find it more difficult to sell their shares.

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

As of December 31, 2015, we had a number of agreements or obligations that may result in dilution to investors. These include:

● warrants to purchase a total of approximately 4,926,119 shares of our common stock at a current weighted average exercise price of approximately

$0.74; and

● options to purchase approximately 2,768,612 shares of our common stock at a current weighted average exercise price of approximately $2.13.

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.

Additionally, the sale, or even the possibility of the sale, of the shares of common stock underlying these warrants and options could have an adverse effect on
the market price for our securities or on our ability to obtain future financing.

34

 
 
 
 
 
 
 
 
 
 
 
Anti-takeover provisions in our stockholder rights plan and under Delaware law could make a third party acquisition of the Company difficult.

Our stockholder rights plan contains provisions that could make it more difficult for a third party to acquire us, even if doing so might be deemed beneficial
by our stockholders. These provisions could limit the price that investors might be willing to pay in the future for shares of our common stock. We are also
subject  to  certain  provisions  of  Delaware  law  that  could  delay,  deter  or  prevent  a  change  in  control  of  the  Company.  The  rights  issued  pursuant  to  our
stockholder  rights  plan  will  become  exercisable  the  tenth  day  after  a  person  or  group  announces  acquisition  of  15%  or  more  of  our  common  stock  or
commences, or announces an intention to make, a tender or exchange offer the consummation of which would result in ownership by the person or group of
15% or more of our common stock. If the rights become exercisable, the holders of the rights (other than the person acquiring 15% or more of our common
stock) will be entitled to acquire, in exchange for the rights’ exercise price, shares of our common stock or shares of any company in which we are merged,
with a value equal to twice the rights’ exercise price.

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

Our common stock has from time to time been “thinly-traded,” meaning that the number of persons interested in purchasing our common stock 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 will develop or be sustained, or that current trading levels will be sustained.

Since  our  common  stock  is  not  listed  on  a  national  securities  exchange,  U.S.  holders  of  warrants  may  not  be  able  to  exercise  their  warrants  without
compliance with applicable state securities laws and the value of your warrants may be significantly reduced.

Since our securities are not listed for trading on a national exchange, the exercise of the warrants by U.S. holders may not be exempt from state securities
laws. As a result, depending on the state of residence of a holder of the warrants, a U.S. holder may not be able to exercise its warrants unless we comply with
any state securities law requirements necessary to permit such exercise or an exemption applies. Although we plan to use our reasonable efforts to assure that
U.S. holders will be able to exercise their warrants under applicable state securities laws if no exemption exists, there is no assurance that we will be able to
do so. As a result, your ability to exercise your warrants may be limited. The value of the warrants may be significantly reduced if U.S. holders are not able to
exercise their warrants under applicable state securities laws.

Our common stock is deemed to be a “penny stock,” which may make it more difficult for investors to sell their shares due to suitability requirements.

Our common stock is subject to Rule 15g-1 through 15g-9 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which imposes
certain sales practice requirements on broker-dealers which sell our common stock to persons other than established customers and “accredited investors”
(generally,  individuals  with  a  net  worth  in  excess  of  $1,000,000  or  annual  incomes  exceeding  $200,000  (or  $300,000  together  with  their  spouses)).  For
transactions covered by this rule, a broker-dealer must make a special suitability determination for the purchaser and have received the purchaser’s written
consent  to  the  transaction  prior  to  the  sale.  This  rule  adversely  affects  the  ability  of  broker-dealers  to  sell  our  common  stock  and  the  ability  of  our
stockholders to sell their shares of common stock.

35

 
 
 
 
 
 
 
 
 
 
Additionally, our common stock is subject to the SEC regulations for “penny stock.” Penny stock includes any equity security that is not listed on a national
exchange and has a market price of less than $5.00 per share, subject to certain exceptions. The regulations require that prior to any non-exempt buy/sell
transaction in a penny stock, a disclosure schedule set forth by the SEC relating to the penny stock market must be delivered to the purchaser of such penny
stock.  This  disclosure  must  include  the  amount  of  commissions  payable  to  both  the  broker-dealer  and  the  registered  representative  and  current  price
quotations for the common stock. The regulations also require that monthly statements be sent to holders of penny stock that disclose recent price information
for the penny stock and information of the limited market for penny stocks. These requirements adversely affect the market liquidity of our common stock.

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 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 will appreciate in value or even maintain the price at
which our stockholders have purchased their shares.

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

In  the  event  of  a  liquidation,  dissolution  or  winding-up  of  the  Company,  whether  voluntary  or  involuntary,  the  proceeds  and/or  assets  of  the  Company
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 of the Company. In this event, our stockholders could lose some or all of their investment.

The sale or issuance of our common stock to Lincoln Park may cause dilution and the sale of the shares of common stock acquired by Lincoln Park, or
the perception that such sales may occur, could cause the price of our common stock to fall.

On November 18, 2013, we entered into a purchase agreement (the “2013 Purchase Agreement”) with Lincoln Park Capital Fund, LLC (“Lincoln Park”),
pursuant to which Lincoln Park has committed to purchase up to $10.6 million of our common stock.  Concurrently with the execution of the 2013 Purchase
Agreement, we issued 97,656 shares of our common stock to Lincoln Park as a partial fee for its commitment to purchase shares of our common stock under
the 2013 Purchase Agreement and 285,714 shares of common stock for an aggregate price of $600,000. From November 18, 2013 through December 31,
2015, we sold 1,050,000 additional shares to Lincoln Park and issued 22,091 additional shares to Lincoln Park as additional commitment shares under the
2013 Purchase Agreement and received proceeds of $1,809,652. The shares that may be sold pursuant to the 2013 Purchase Agreement in the future may be
sold  by  us  to  Lincoln  Park  at  our  discretion  from  time  to  time  over  the  remaining  term  of  approximately  nine  months  from  the  date  of  this  report.    The
purchase price for the shares that we may sell to Lincoln Park under the 2013 Purchase Agreement will fluctuate based on the price of our common stock.  We
generally have the right to control the timing and amount of any sales of our shares to Lincoln Park, except that, pursuant to the terms of the 2013 Purchase
Agreement, we would be unable to sell shares to Lincoln Park if and when the closing sale price of our common stock is below $1.00 per share, subject to
adjustment as set forth in the 2013 Purchase Agreement. 

We entered into an additional purchase agreement (the “2016 Purchase Agreement”) with Lincoln Park on March 22, 2016, with the intention that the 2016
Purchase Agreement will replace the 2013 Purchase Agreement once the registration statement registering the resale of the shares of common stock sold to
Lincoln Park under the 2016 Purchase Agreement is declared effective by the SEC.  Pursuant to the 2016 Purchase Agreement, Lincoln Park has committed
to  purchase  up  to  $12  million  of  our  common  stock.    Concurrently  with  the  execution  of  the  2016  Purchase Agreement,  we  issued  100,000  shares  of  our
common stock to Lincoln Park as a partial fee for its commitment to purchase shares of our common stock under the 2016 Purchase Agreement. The shares
that may be sold pursuant to the 2016 Purchase Agreement may be sold by us to Lincoln Park at our sole discretion from time to time over the remaining term
of approximately 36 months from the date the registration statement registering the resale of the shares of common stock sold to Lincoln Park under the 2016
Purchase Agreement is declared effective by the SEC.  The purchase price for the shares that we may sell to Lincoln Park under the 2016 Purchase Agreement
will fluctuate based on the price of our common stock.  We have the right to control the timing and amount of any sales of our shares to Lincoln Park, except
that,  pursuant  to  the  terms  of  our  agreements  with  Lincoln  Park,  we  would  be  unable  to  sell  shares  to  Lincoln  Park  that  would  cause  Lincoln  Park  to
beneficially own more than 4.99% of our issued and outstanding common stock.

Depending on market liquidity at the time, sales of shares under the 2013 Purchase Agreement or the 2016 Purchase Agreement may cause the trading price
of  our  common  stock  to  fall.    Additionally,  further  sales  of  our  common  stock,  if  any,  to  Lincoln  Park  under  the  2013  Purchase  Agreement  or  the  2016
Purchase Agreement will depend upon market conditions and other factors to be determined by us.  Lincoln Park may ultimately purchase all, some or none
of the shares of our common stock that may be sold pursuant to the 2013 Purchase Agreement or the 2016 Purchase Agreement and, after it has acquired
shares, Lincoln Park may sell all, some or none of those shares.  Therefore, sales to Lincoln Park by us could result in substantial dilution to the interests of
other holders of our common stock.  Additionally, the sale of a substantial number of shares of our common stock to Lincoln Park, or the anticipation of such
sales, 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.

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 Inc. 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 43,067 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 $250,000 in cash and issued 1,849,113 shares
of common stock in the aggregate to Hy Biopharma and its assignees, 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. Also on September 3, 2014, we
entered into the 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. 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  5,200  square  feet  of  office  space  at  29  Emmons  Drive,  Suite  C-10,  Princeton,  New  Jersey  08540.  This  office  space
currently serves as our corporate headquarters. In December 2014, we entered into a lease agreement through May 31, 2018 for existing and expanded office
space. The rent for the first 12 months was approximately $12,300 per month, or approximately $20.85 per square foot. The rent increased to approximately
$12,375 per month, or approximately $20.95 per square foot, for the next 12 months, and thereafter to approximately $12,460 per month, or approximately
$21.13 per square foot 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 were incorporated in Delaware in 1987. 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 first-in-class photodynamic therapy (SGX301) utilizing topical synthetic hypericin activated with safe
visible light for the treatment of cutaneous T-cell lymphoma (“CTCL”), 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), and our novel innate defense regulator (“IDR”) technology, dusquetide (SGX942) for the treatment of oral mucositis in head
and neck cancer.

Our Vaccines/BioDefense business segment includes active development programs for RiVax™, our ricin toxin vaccine candidate, OrbeShield®, our GI acute
radiation  syndrome  (“GI  ARS”)  therapeutic  candidate  and  SGX943,  our  melioidosis  therapeutic  candidate.  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.  We  plan  to  use  the  funds  received  under  our  government  contracts  with  the  Biomedical  Advanced  Research  and
Development Authority (“BARDA”) and NIAID to advance the development of OrbeShield® for the treatment of GI ARS.

An outline for our business strategy follows:

● Complete enrollment and report preliminary results in our pivotal Phase 3 clinical trial of SGX301 for the treatment of CTCL;
● Initiate a Phase 3 clinical trial of SGX203, for the treatment of pediatric Crohn’s disease;
● Continue to collect the long-term follow-up safety data from the SGX942 Phase 2 proof-of-concept study in the treatment of oral mucositis in head
and neck cancer patients and publish the findings from the SGX942 Phase 2 proof-of-concept study in the treatment of oral mucositis in head and
neck cancer patients;

● Obtain FDA agreement on a pivotal Phase 2b/3 protocol of SGX942 in the treatment of oral mucositis in head and neck cancer patients;
● Continue  development  of  RiVax™  in  combination  with  our  ThermoVax®  technology,  to  develop  new  heat  stable  vaccines  in  biodefense  and

infectious diseases with the potential to collaborate and/or partner with other companies in these areas;

● Advance the preclinical and manufacturing development of OrbeShield® as a biodefense medical countermeasure for the treatment of GI ARS;
● Continue to apply for and secure additional government funding for each of our BioTherapeutics and Vaccines/BioDefense programs through grants,

contracts and/or procurements;

● Acquire or in-license new clinical-stage compounds for development; and
● Explore other business development and merger/acquisition strategies.

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.

Intangible Assets

One of the most significant estimates or judgments that we make is whether to capitalize or expense patent and license costs. We make 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, we capitalized payments made to legal firms that are engaged in filing and protecting
rights to intellectual property for our current product candidates in both the domestic and international markets. We believe that patent rights are one of our
most valuable assets. Patents and patent applications are key components of intellectual property, especially in the early stage of product development, as their
purchase and maintenance gives us access to key product development rights from our academic and industry partners. These rights can also be sold or sub-
licensed as part of our strategy to partner our product candidates 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 our rights, and perhaps to extend
the lives of the patents. We capitalize such costs and amortize intangibles on a straight-line basis over their expected useful life – generally a period of 11 to
16 years.

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.

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 us on December 31, 2015. 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.

41

 
 
 
 
 
 
 
 
 
 
 
 
 
 
The carrying amounts reported in the consolidated balance sheet for cash and cash equivalents, contract and grants receivable, accounts payable and accrued
compensation approximate their fair value based on the short-term maturity of these instruments. We recognize all derivative financial instruments as assets or
liabilities in the financial statements and measure them at fair value with changes in fair value reflected as current period income or loss unless the derivatives
qualify as hedges. As a result, certain warrants issued in connection with our June 2013 offering were accounted for as derivatives.

Revenue Recognition

Our 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 we incur 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.

Accounting for Warrants

We considered FASB ASC 815, Evaluating Whether an Instrument is Considered Indexed to an Entity’s Own Stock, which provides guidance for determining
whether an equity-linked financial instrument (or embedded feature) issued by an entity is indexed to the entity’s stock and therefore, qualifying for the first
part  of  the  scope  exception  in  paragraph  815-10-15.  We  evaluated  the  provisions  in  our  outstanding  warrants  and  determined  that  warrants  issued  in
connection with our June 2013 registered public offering contain provisions that protect holders from a decline in the issue price of our common stock (or
“down-round” provisions) and contain net settlement provisions. Consequently, these warrants are recognized as liabilities at their fair value on the date of
grant and remeasured at fair value on each reporting date. All other warrants issued were indexed to our own stock and therefore are accounted for as equity
instruments for 2015 and 2014.

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 vest 25% on the grant date, then 25% each
subsequent year for a period of three years. Stock options vest over each three-month period from the date of issuance to the end of the three year period.
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,  we  issue  restricted  shares  of  our  common  stock  to  vendors  and  consultants  as  compensation  for  services  performed.  Typically  these
instruments vest upon issuance and therefore the entire stock 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.

42

 
 
 
 
 
 
 
 
 
 
 
 
 
The weighted average fair value of each option grant made during 2015 and 2014 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.

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 bases. 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,  2015  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  2015  and  2014.  Additionally,  the  Company  has  not
recorded an asset for unrecognized tax benefits or a liability for uncertain tax positions at December 31, 2015 and 2014.

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 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, 2015 Compared to 2014

For the year ended December 31, 2015, we had a net loss of $7,831,230 as compared to a net loss of $6,706,972 for the prior year, representing an increased
loss of $1,124,258 or 17%. Included in the net loss for December 31, 2015 is a non-cash expense of $1,201,870 versus a non-cash gain of $3,436,195 for
December 31, 2014 which represents the change in the fair value of the warrant liability related to warrants issued in connection with our registered public
offering in June 2013.

For  the  year  ended  December  31,  2015  and  2014,  revenues  and  associated  costs  relate  to  government  contracts  and  grants  awarded  in  support  of  the
development of ThermoVax®, RiVax™ GI-ARS and OrbeShield® in  GI  ARS.  For  the  year  ended  December  31,  2015,  we  had  revenues  of  $8,768,390  as
compared to $7,043,016 for the prior year, representing an increase of $1,725,374 or 24%. The increase in revenues was a result of research and development
activities performed under our government contracts associated with OrbeShield® and RiVax™.

We  incurred  costs  related  to  contract  and  grant  revenues  in  the  year  ended  December  31,  2015  and  2014  of  $6,882,204  and  $5,313,855,  respectively,
representing an increase of $1,568,349 or 30%. These costs primarily relate to payments made to subcontractors and allocated employee costs in connection
with  research  performed  pursuant  to  contracts  and  grants.  The  fluctuations  are  due  to  the  development  activity  performed  on  the  contracts  and  grants
discussed above.

Our gross profit for the year ended December 31, 2015 was $1,886,186 as compared to $1,729,161 for the prior year, representing an increase of $157,025 or
9%. This increase is due primarily to the increased activity in our OrbeShield® and RiVax™ contracts.

Research and development, including acquired in-process research and development costs, decreased by $3,686,696 or 41%, to $5,399,839 for the year ended
December 31, 2015 as compared to $9,086,535 for the prior year. This decrease is primarily related to the 2014 acquisition of Hypericin, SGX 301, for which
we  issued  common  stock  with  a  value  of  $3,750,000  and  paid  cash  of  $250,000  which  was  recognized  as  acquired  in-process  research  and  development
expense. During 2015, we also completed the Phase 2 clinical trial with SGX942 for patients suffering from oral mucositis associated with their CRT for head
and neck cancer and in December 2015, initiated the pivotal Phase 3 clinical trial of SGX301 for the treatment of CTCL.

General and administrative expenses increased by $192,648 or 6%, to $3,596,623 for the year ended December 31, 2015, as compared to $3,403,975 for the
prior year. This increase is primarily related to an increase in outside professional services.

Other  income  (expense)  for  the  year  ended  December  31,  2015  was  $(1,209,887)  as  compared  to  $3,437,505  for  the  prior  year.  The  change  is  primarily
related to non-cash expense of $(1,201,870) which represents the change in the fair value of the warrant liability related to warrants issued in connection with
our June 2013 registered public offering for the year ended December 31, 2015 as compared to non-cash income of $3,436,195 from the change for the year
ended December 31, 2014.

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, during the year ended December 31,
2015,  we  sold  New  Jersey  NOL  carryforwards,  resulting  in  the  recognition  of  $488,933  of  income  tax  benefit,  net  of  transaction  costs  as  compared  to
$616,872 for the year ended December 31, 2014. 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 year ended December 31, 2015 and December 31, 2014: Vaccines/BioDefense and BioTherapeutics.

Revenues for the Vaccines/BioDefense business segment for the year ended December 31, 2015 were $8,754,418 as compared to $6,756,388 for the year
ended December 31, 2014, representing an increase of $1,998,030 or 30%. This increase in revenues was a result of our OrbeShield® and RiVax™ contracts.
Revenues  for  the  BioTherapeutics  business  segment  for  the  year  ended  December  31,  2015  were  $13,972  as  compared  to  $286,628  for  the  year  ended
December 31, 2014, representing a decrease of $272,656 or 95%. This decrease is primarily related to work performed under our oral mucositis grant which
expired in early 2015.

Income from operations for the Vaccines/BioDefense business segment for the year ended December 31, 2015 was $1,263,709 as compared to $807,164 for
the year ended December 31, 2014. Income from operations is primarily attributable to our gross margins related to our government contracts. Loss from
operations for the BioTherapeutics business segment for the year ended December 31, 2015 was $4,487,988 as compared to $7,674,381 for the year ended
December 31, 2014, representing a decrease of $3,186,393. This decreased loss is due primarily to the 2014 acquisition of Hypericin, SGX 301, for which we
issued common stock with a value of $3,750,000 and paid cash of $250,000 which was recognized as acquired in-process research and development expense,
offset by expenses in 2015 related to the Phase 2 clinical trial with SGX942 for patients suffering from oral mucositis associated with their CRT for head and
neck cancer and the initiation of the pivotal Phase 3 clinical trial of SGX301 for the treatment of CTCL.

Amortization and depreciation expense for the Vaccines/BioDefense business segment for the year ended December 31, 2015 was $39,925 as compared to
$39,625  for  the  year  ended  December  31,  2014.  Amortization  and  depreciation  expense  for  the  BioTherapeutics  business  segment  for  the  year  ended
December 31, 2015 was $199,661 as compared to $199,196 for the year ended December 31, 2014.

Financial Condition and Liquidity

Cash and Working Capital

As of December 31, 2015, we had cash and cash equivalents of $4,921,545 as compared to $5,525,094 as of December 31, 2014, representing a decrease of
$603,549 or 11%. As of December 31, 2015, we had working capital of $2,179,694 which excludes a non-cash warrant liability of $2,434,101 as compared to
working  capital  of  $3,174,214  as  of  December  31,  2014,  representing  a  decrease  of  $994,520  or  31%.  The  decrease  in  working  capital  was  primarily  the
result of expenditures in 2015 related to support the completion of our Phase 2 clinical trial of SGX942 and the initiation of the pivotal Phase 3 clinical trial of
SGX301 for the treatment of CTCL offset by $4,804,857 in various financing activities.

Based on our current rate of cash outflows, cash on hand, proceeds from government contract and grant programs, proceeds available from our equity lines
and  proceeds  from  the  State  of  New  Jersey  Technology  Business  Tax  Certificate  Transfer  Program,  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.

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

● We have  up  to  $43.0  million  in  active  government  contract  funding  still  available  to  support  our associated research programs through 2016 and

beyond. We plan to submit additional contract and grant applications for further support of these 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 pursue NOL sales in the state of New Jersey pursuant to our Technology Business Tax Certificate Transfer Program. Based on the receipt of

$488,933 in proceeds from the sale of NJ NOL in 2015, we expect to participate in this program during 2016 and beyond;

● We have an aggregate of $20.2 million available from equity facilities through 2019; 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 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 next 12 months to be approximately $12.9 million before any grant reimbursements, of
which  $5.3  million  relates  to  the  BioTherapeutics  business  and  $7.6  million  relates  to  the  Vaccines/BioDefense  business.  We  anticipate  contract
reimbursements  in  the  next  12  months  of  approximately  $7.6  million  to  offset  research  and  development  expenses  in  the  Vaccines/BioDefense  business
segment.

Contractual Obligations

We have commitments of approximately $500,000 at December 31, 2015 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.

In December 2014, we entered into a lease agreement through May 31, 2018 for existing and expanded office space. The rent for the first 12 months was
approximately  $12,300  per  month,  or  approximately  $20.85  per  square  foot.  This  rent  increased  to  approximately  $12,375  per  month,  or  approximately
$20.95 per square foot, for the next 12 months, and thereafter will increase to approximately $12,460 per month, or approximately $21.13 per square foot for
the remainder of the lease.

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 $250,000 in cash and issued 1,849,113 shares of common stock with a fair value based on 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 additional payments of up to $10.0 million, if and when achieved. Payments will be
payable in restricted securities of the Company; provided that Hy BioPharma’s ownership of our securities is not to exceed 19.9% of our outstanding stock.

In February 2007, our Board of Directors authorized the issuance of 50,000 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. Dr. Schaber’s amended employment agreement includes our obligation
to issue such shares if such event occurs.

Employees with employment contracts have severance agreements that will provide separation benefits from the Company if they are involuntarily separated
from employment.

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

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.

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,  2015.  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, 2015, 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 22, 2016, we entered into a purchase agreement with Lincoln Park Capital Fund, LLC (“Lincoln Park”), pursuant to which Lincoln Park has agreed
to  purchase  up  to  $12  million  of  shares  of  our  common  stock  from  us,  from  time  to  time  and  subject  to  certain  limitations.  Also  on  March  22,  2016,  we
entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with Lincoln Park, pursuant to which we agreed to file with the U.S.
Securities and Exchange Commission (the “SEC”) a registration statement (the “Registration Statement”) to register for resale under the Securities Act of
1933, as amended (the “Securities Act”), the shares of our common stock that have been or may be issued to Lincoln Park under the Purchase Agreement.

After the SEC has declared the Registration Statement effective, we have the right at our sole discretion, over a 36-month period, to sell up to $12 million of
shares of our common stock to Lincoln Park in amounts up to $750,000 per sale, provided certain conditions in the Purchase Agreement are met. In addition,
we may direct Lincoln Park to purchase additional shares in accordance with the terms of the Purchase Agreement.

If, and/or when, we sell stock, we will control the timing and amount of sales, if any, of our common stock to Lincoln Park under the Purchase Agreement;
provided that in no event will such shares be sold to Lincoln Park where such sale would result in Lincoln Park’s beneficial ownership exceeding 4.99% of
the then outstanding shares of our common stock. The purchase price of the shares related to the $12 million of funding will be based on prevailing market
prices of our common stock, calculated using the formula set forth in the Purchase Agreement.

In consideration for entering into the Purchase Agreement, we issued to Lincoln Park 100,000 shares of our common stock as a commitment fee and will
issue  up  to  500,000  additional  shares  pro  rata,  when  and  if,  Lincoln  Park  purchases  at  our  request  the  $12  million  commitment.  We  may  terminate  the
Purchase Agreement at any time at our discretion without any cost to us. The proceeds we receive pursuant to the Purchase Agreement are expected to be
used to further develop our product candidates and for general corporate purposes.

The securities issued pursuant to the Purchase Agreement were exempt from registration pursuant to the provisions of Section 4(a)(2) of the Securities Act
and  Rule  506  of  Regulation  D  promulgated  thereunder.  Lincoln  Park  represented  to  us  that  it  is  an  “accredited  investor”  as  defined  in  Rule  501(a)  of
Regulation  D  promulgated  under  the  Securities  Act;  is  knowledgeable,  sophisticated  and  experienced  in  making  investment  decisions  of  this  kind;  and
received adequate information about us or had adequate access to information about us.

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 and Lapointe, 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 the Company 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, 2015, 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  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),  Dr.  Brughera  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 and Dr. Zeldis 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 reviewed Dr. Brughera’s relationship as the Global Head of the Rare Disease Franchise for Sigma-
Tau SpA., an affiliate of Sigma-Tau Pharmaceuticals, Inc., which owns approximately 9.4% of the issued and outstanding shares of our common stock. Our
Board of Directors determined that Dr. Brughera’s position with Sigma-Tau Spa. would not impair his ability to exercise independent judgment.  

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.

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  was  renewed  in
December 27, 2007 for an additional term of three years. We agreed to issue him options to purchase 125,000 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

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. Dr. Schaber’s employment agreement automatically
renewed in December 2013 for an additional term of three years.

salary. We also agreed to issue him options to purchase 40,000 shares of our common stock with one-third immediately vesting and the remainder vesting
over  three  years.  Upon  termination  without  “Just  Cause”,  as  defined  in  Mr.  Warusz’s  employment  agreement,  we  would  pay  Mr.  Warusz  three  months  of

him  options  to  purchase  100,000  shares  of  our  common  stock  with  one-third  immediately  vesting  and  the  remainder  vesting  over  three  years.  Upon
termination without “Just Cause”, as defined in Dr. Straube’s employment agreement, we would pay Dr. Straube three months of severance, accrued bonuses

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

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 the Company’s 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.

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 1,250,000 shares, bringing the total shares reserved for issuance under the plan to 3,000,000 shares. In April

shares of our common stock are available for issuance under the 2015 Equity Incentive Plan. The following table provides information, as of December 31,

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

of  cutaneous  T-cell  lymphoma  (“CTCL”),  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),
and it’s novel innate defense regulator (“IDR”) technology (SGX942) for the treatment of oral mucositis in head and neck cancer.

The Company’s Vaccines/BioDefense business segment includes active development programs for RiVax™, its ricin toxin vaccine candidate, VeloThrax™,
an  anthrax  vaccine  candidate,  OrbeShield™,  a  GI  acute  radiation  syndrome  (“GI  ARS”)  therapeutic  candidate  and  SGX943,  a  melioidosis  therapeutic
candidate. The development of the vaccine programs 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  plans  to  use  the  funds  received  under  the
government  contracts  with  the  Biomedical  Advanced  Research  and  Development  Authority  (“BARDA”)  and  NIAID  to  advance  the  development  of
OrbeShield™ for the treatment of GI ARS.

The  Company  generates  revenues  under  government  grants  primarily  from  the  National  Institutes  of  Health  (the  “NIH”)  and  government  contracts  from
BARDA and NIAID.

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, litigation, and product liability.

Liquidity

As of December 31, 2015, the Company had cash and cash equivalents of $4,921,545 as compared to $5,525,094 as of December 31, 2014, representing a
decrease  of  $603,549  or  11%.  The  decrease  in  cash  was  primarily  due  to  net  cash  used  in  operations  of  $5,386,308  partially  offset  by  cash  provided  by
financing activities of $4,804,857. As of December 31, 2015, the Company had working capital of $2,179,694, which excludes a non-cash warrant liability of
$2,434,101, as compared to working capital of $3,174,214 as of December 31, 2014, representing a decrease of $994,520 or 31%. The decrease in working
capital was primarily the result of expenditures to support the completion of the Phase 2 clinical trial of SGX942 and the initiation of the pivotal Phase 3
clinical trial of SGX301 for the treatment of CTCL offset by the $4,804,857 in various financing activities.

Based on the Company’s current rate of cash outflows, cash on hand, proceeds from its government contract and grant programs, availability of funds from
equity lines and proceeds from the state of New Jersey Technology Business Tax Certificate Transfer Program, 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.

F-6

 
 
 
 
 
 
 
 
 
 
 
 
 
Management’s business plan can be outlined as follows:

● Complete enrollment and report preliminary results in the pivotal Phase 3 clinical trial of SGX301 for the treatment of CTCL;
● Initiate a Phase 3 clinical trial of oral BDP, known as SGX203, for the treatment of pediatric Crohn’s disease;
● Continue to collect the long-term follow-up safety data from the SGX942 Phase 2 proof-of-concept study in the treatment of oral mucositis in head

and neck cancer patients and publish the findings from this study;

● Obtain FDA agreement on a pivotal Phase 2b/3 protocol of SGX942 in the treatment of oral mucositis in head and neck cancer patients;
● Continue development of RiVax™ in combination with ThermoVax® technology to develop new heat stable vaccines in biodefense and infectious

diseases with the potential to collaborate and/or partner with other companies in these areas;

● Advance the preclinical and manufacturing development of OrbeShield™ as a biodefense medical countermeasure for the treatment of GI ARS;
● Continue to apply for and secure additional government funding for each of our BioTherapeutics and Vaccines/BioDefense programs through grants,

contracts and/or procurements;

● Acquire or in-license new clinical-stage compounds for development; and
● Explore other business development and merger/acquisition strategies.

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

● The Company has up to $43.0 million in active government contract funding still available to support its associated research programs through 2016
and  beyond.  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 pursue Net Operating Loss (“NOL”) sales in the state of New Jersey pursuant to its Technology Business Tax Certificate Transfer
Program. Based on the receipt of $488,933 in proceeds of the sale of NJ NOL in 2015, the Company expects to participate in the program during
2016 and beyond;

● The Company has an aggregate of $20.2 million available from equity facilities through 2019; and
● The Company 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 its operations, respond to competitive pressures, develop new products and services, and to support new strategic
partnerships.  The  Company  is  currently  evaluating  additional  equity  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.

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 unbilled amounts due from various grants from the NIH and contracts from BARDA and 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.

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, 2015 and 2014.

The Company did not capitalize any patent related costs during the years ended December 31, 2015 or 2014.

Impairment of Long-Lived Assets

Office furniture and equipment and intangible assets 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.

The Company did not record any impairment of long-lived assets for the years ended December 31, 2015 or 2014.

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, 2015. 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.

F-8

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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,  notes
payable and accrued compensation approximate their fair value based on the short-term maturity of these instruments. The Company recognizes all derivative
financial instruments as assets or liabilities in the financial statements and measures them at fair value with changes in fair value reflected as current period
income or loss unless the derivatives qualify as hedges. As a result, certain warrants issued in connection with the Company’s June 2013 registered public
offering were accounted for as derivatives. See Note 5, Warrant Liability.

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.

Accounting for Warrants

The Company considered FASB ASC 815, Evaluating Whether an Instrument is Considered Indexed to an Entity’s Own Stock, which provides guidance for
determining whether an equity-linked financial instrument (or embedded feature) issued by an entity is indexed to the entity’s stock, and, therefore, qualifying
for  the  first  part  of  the  scope  exception  in  paragraph  815-10-15.  The  Company  evaluated  the  provisions  in  its  outstanding  warrants  and  determined  that
warrants issued in connection with the Company’s June 2013 registered public offering contains provisions that protect holders from a decline in the issue
price of the Company’s common stock (or “down-round” provisions) and contain net settlement provisions. Consequently, these warrants are recognized as
liabilities at their fair value on the date of grant and remeasured at fair value on each reporting date. All other warrants issued were indexed to the Company’s
stock and therefore are accounted for as equity instruments for 2015 and 2014.

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 vest 25% on the grant date, then 25% each
subsequent year for a period of three years. Stock options vest over each three-month period from the date of issuance to the end of the three year period.
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.

For the year ended December 31, 2015 the Company issued 605,340 stock options at a weighted average exercise price of $1.19 per share. The fair value of
options issued during the years ended December 31, 2015 and 2014 was estimated to be $1.22 and $1.48 per share, respectively, using the Black-Scholes
option-pricing model and the following assumptions:

● a dividend yield of 0%;
● an expected life of 4 years;
● volatilities ranging from 121% - 141% and 128% - 165% for 2015 and 2014, respectively;
● forfeitures at a rate of 12%; and
● risk-free interest rates ranging from .98% to 1.53% and 1.05% to 1.43% for 2015 and 2014, respectively.

The weighted average fair value of each option grant made during 2015 and 2014 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.

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 bases. 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. 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 2015 and 2014. Additionally, the Company has not recorded an asset
for unrecognized tax benefits or a liability for uncertain tax positions at December 31, 2015 and 2014.

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.

Company’s stock options and warrants outstanding at December 31, 2015 were $2.13 and $0.74 per share, 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 August 2014, FASB issued Accounting Standards Update (“ASU”) No. 2014-15, “Presentation of Financial Statements - Going Concern (Subtopic 205-
40):  Disclosure  of  Uncertainties  about  an  Entity’s  Ability  to  Continue  as  a  Going  Concern.”  The  amendments  in  this  ASU  are  intended  to  define
management’s  responsibility  to  evaluate  whether  there  is  substantial  doubt  about  an  entity’s  ability  to  continue  as  a  going  concern  and  to  provide  related
footnote disclosures. Specifically, this ASU provides a definition of the term substantial doubt and requires an assessment for a period of one year after the
date that the financial statements are issued (or available to be issued). It also requires certain disclosures when substantial doubt is alleviated as a result of
consideration of management’s plans and requires an express statement and other disclosures when substantial doubt is not alleviated. The new standard will
be  effective  for  annual  periods  ending  after  December  15,  2016,  and  interim  periods  thereafter,  with  early  adoption  permitted.  The  Company  is  currently
evaluating the impact the adoption of this standard will have on the Company's consolidated financial statements and disclosures.

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 recognizing lease assets and lease liabilities on the balance sheet 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 is evaluating the impact of the adoption of this update on our consolidated financial statements and related disclosures.

Note 4. Notes Payable

On July 29, 2015, the Company entered into equity purchase agreements (the “Equity Line Purchase Agreements”) and registration rights agreements with
certain  accredited  institutional  investors.  Under  the  Equity  Line  Purchase  Agreements,  the  investors  have  agreed  to  purchase  from  the  Company  up  to  an
aggregate of $10 million worth of shares of common stock, from time to time.

In consideration for entering into the Equity Line Purchase Agreements, the Company issued to the investors promissory notes having an aggregate principal
amount of $300,000, which were recorded as stock issuance costs. The promissory notes are payable by April 15, 2016, with an issuance date present value of
$282,071.  The  promissory  notes  did  not  include  terms  for  interest,  therefore  the  interest  was  imputed  at  9%.  Total  discount  amortization  of  $10,648  was
recorded as interest expense for the year ended December 31, 2015. The discount is being accreted over the term of the promissory notes using the effective
interest rate method.

Note 5. Warrant Liability

Warrants issued in connection with the Company’s June 2013 registered public offering contain provisions that protect holders from a decline in the issue
price  of  its  common  stock  (or  “down-round”  provision)  and  contain  net  settlement  provisions. As  a  result,  the  Company  accounts  for  these  warrants  as
liabilities instead of equity instruments. Down-round provisions reduce the exercise or conversion price of a warrant if the Company issues equity shares for a
price  that  is  lower  than  the  exercise  or  conversion  price  of  the  warrants.  Net  settlement  provisions  allow  the  holder  of  the  warrant  to  surrender  shares
underlying the warrant equal to the exercise price as payment of its exercise price, instead of exercising the warrant by paying cash. The Company evaluates
whether warrants to acquire its common stock contain provisions that protect holders from declines in the stock price or otherwise could result in modification
of the exercise price and/or shares to be issued under the respective warrant agreements based on a variable that is not an input to the fair value of a “fixed for
fixed” option. As a result of the Company’s December 2014 registered public unit offering, the exercise price of warrants outstanding in connection with the
public offering completed in June 2013 was adjusted to $0.61 per share. As a result of the Company’s December 2015 drawdown on the Equity Line Purchase
Agreement, the exercise price of warrants outstanding in connection with the public offering completed in June 2013 was adjusted to $0.51 per share.

The Company recognized these warrants as liabilities at their fair value on the date of grant and remeasures them to fair value on each reporting date.

The Company recognized an initial warrant liability for the warrants issued in connection with the registered public offering completed in June 2013 totaling
$4,827,788, which was based on the June 25, 2013 closing price of a share of the Company’s common stock as reported on OTC Markets of $0.96. During
the  year  ended  December  31,  2014,  143,004  shares  of  common  were  issued  upon  586,081  warrants  exercised  on  a  cashless  basis.  On  January  22,  2014,
250,000 warrants were exercised and on August 19, 2014, 336,081 warrants were exercised. The fair value of the warrants exercised in 2014, or $1,055,490
was reclassified from warrant liability to additional paid-in capital on the respective exercise dates. During the year ended December 31, 2015, 1,686,429
warrants were exercised. The fair value of the warrants exercised in 2015, or $2,557,331 was reclassified from warrant liability to additional paid-in capital on
the respective exercise dates. On December 31, 2015, the closing price of the Company’s common stock as reported on OTC Markets was $1.13. Due to the
fluctuations in the market value of the Company’s common stock from December 31, 2014 through December 31, 2015, the Company recognized a non-cash
expense of $1,201,870 for the change in the fair value of the warrant liability for 2015.

The Company has gross NOLs at December 31, 2015 of approximately $90,891,000 for federal tax purposes and approximately $5,273,000 of New Jersey
NOL carry forwards remaining after the sale of unused net operating loss carry forwards, portions of which will begin to expire in 2018. In addition, the
Company has $4,909,000 of various tax credits which expire from 2018 to 2034. 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
years ended December 31, 2015 and 2014, 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 net operating loss carryforwards to other New Jersey-based corporate taxpayers, the Company
sold  New  Jersey  net  operating  loss  carryforwards,  resulting  in  the  recognition  of  $488,933  and  $616,872  of  income  tax  benefit,  net  of  transaction  costs,
respectively. 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, 2015 and 2014 were as follows:

Equity Line Purchase Agreement

On July 29, 2015, the Company entered into the Equity Line Purchase Agreements and a registration rights agreements with accredited institutional investors,
Kodiak Capital Group, LLC (“Kodiak Capital”), Kingsbrook Opportunities Master Fund LP (“Kingsbrook”) and River North Equity, LLC (“River North”
and, together with Kodiak Capital and Kingsbrook, the “Investors”). Under the Equity Line Purchase Agreements, the Investors agreed to purchase from the
Company up to an aggregate of $10 million worth of shares of common stock, from time to time. In accordance with the registration rights agreements, the
Company has filed with the U.S. Securities and Exchange Commission (the “SEC”) a registration statement to register for resale under the Securities Act of
1933, as amended, the shares of common stock that may be issued to the Investors under the Equity Line Purchase Agreements.

From the date that the SEC declared the registration statement effective, in August 2015, until December 31, 2016, the Company has the right to sell up to $5
million, $4 million and $1 million worth of shares of common stock to Kodiak Capital, Kingsbrook and River North, respectively. The Company will control
the timing and amount of future sales, if any, of common stock to the Investors under the Equity Line Purchase Agreements. The purchase price of the shares
will be equal to eighty percent (80%) of the lowest daily volume weighted average price of the common stock for any trading day during the five consecutive
trading  days  immediately  following  the  date  of  the  Company’s  notice  to  the  Investors  requesting  the  purchase.  There  is  no  minimum  amount  that  the
Company may require the Investors to purchase at any one time. The Company may not require the Investors to purchase more than $3 million worth of
shares of common stock during any seven day period and may not require any of the Investors to purchase shares of common stock if such purchase would
result in such Investor’s beneficial ownership exceeding 9.99% of the outstanding common stock.

The  Equity  Line  Purchase  Agreements  contain  customary  representations,  warranties,  covenants,  closing  conditions,  and  indemnification  and  termination
provisions. Each of the Investors has covenanted not to cause or engage in any manner whatsoever any direct or indirect short selling of the common stock.

In consideration for entering into the Equity Line Purchase Agreements, the Company issued to each of the Investors a promissory note having a principal
amount equal to 3% of the total amount committed by such Investor. The principal amount due under the promissory notes does not accrue interest and is
payable by April 15, 2016 (see Note 4).

The Equity Line Purchase Agreements may be terminated by the Company at any time at its discretion without any cost to the Company.

The initial drawdown under the Equity Line Purchase Agreements was $500,000 offset by issuance cost of $453,162, which is included in the Consolidated
Statements of Changes in Shareholders’ Deficiency. Issuance costs include professional fees, 3% commitment fee (promissory notes payable by April 15,
2016) and SEC filing fees.

In December 2015, a second drawdown was made, whereby under the Equity Line Purchase Agreements, the Company issued 3,936,235 shares of common
stock receiving proceeds of $2,000,000.

On  March  7,  2016,  in  accordance  with  the  terms  of  the  Equity  Line  Purchase  Agreements,  the  Company  exercised  its  right  to  terminate  the  Purchase
Agreements upon written notice to the Investors. The Company did not incur any penalties as a result of this termination.

Equity Line

In November 2013, the Company entered into a common stock purchase agreement with Lincoln Park Capital Fund, LLC (“Lincoln Park”). The Lincoln Park
equity facility allows the Company to require Lincoln Park to purchase up to 75,000 shares (“Regular Purchase”) of the Company’s common stock every two
business days, up to an aggregate of $10.6 million over approximately a 36-month period depending on certain conditions, including the quoted market price
of the Company’s common stock on such date. 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 common shares during the twelve business days prior to
the  purchase  date.  Each  Regular  Purchase  shall  not  exceed  $750,000.  Furthermore,  for  each  additional  purchase  by  Lincoln  Park,  additional  commitment
shares in commensurate amounts up to a total of 122,070 shares will be issued based upon the relative proportion of the aggregate amount of $10.0 million.
The  Regular  Purchase  amount  may  be  increased  up  to  100,000  shares  of  common  stock  if  the  closing  price  of  the  common  shares  is  not  below  $2.50.  In
addition to the Regular Purchase and provided that the closing price of the common shares is not below $1.50 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  (“Accelerate  Purchase  Date”)  additional  shares  of
Company stock up to the lesser of (i) two 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 as 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.

During the year ended December 31, 2014, in three separate transactions, the Company sold 225,000 shares of common stock and issued 5,743 commitment
shares receiving net proceeds of $470,475. During the year ended December 31, 2015, in nine separate transactions, the Company sold 825,000 shares of
common stock and issued 16,348 commitment shares receiving net proceeds of $1,339,177.

Note 8. Stock Option Plans and Warrants to Purchase Common Stock

Stock Option Plans

The Amended and Restated 2005 Equity Incentive Plan was replaced by the 2015 Equity Incentive Plan (“2015 Plan”), approved in June 2015, and is divided
into four separate equity programs:

1)

2)

3)

4)

the  Discretionary  Option  Grant  Program,  under  which  eligible  persons  may,  at  the  discretion  of  the  Plan  Administrator,  be  granted  options  to
purchase shares of common stock,
the Salary Investment Option Grant Program, under which eligible employees may elect to have a portion of their base salary invested each year in
options to purchase shares of common stock,
the Automatic Option Grant Program, under which eligible nonemployee Board members will automatically receive options at periodic intervals to
purchase shares of common stock, and
the Director Fee Option Grant Program, under which non-employee Board members may elect to have all, or any portion, of their annual retainer fee
otherwise payable in cash applied to a special option grant.

The 2005 Equity Incentive Plan (“2005 Plan”) also was divided into four separate equity programs:

1)

2)

3)

4)

the Discretionary Option Grant Program, under which eligible persons may, at the discretion of the Plan Administrator, be issued common stock or
granted options to purchase shares of common stock,
the Salary Investment Option Grant Program, under which eligible employees may elect to have a portion of their base salary invested each year in
options to purchase shares of common stock,
the Automatic Option Grant Program, under which eligible nonemployee Board members will automatically receive options at periodic intervals to
purchase shares of common stock, and
the Director Fee Option Grant Program, under which non-employee Board members may elect to have all, or any portion, of their annual retainer fee
otherwise payable in cash applied to a special option grant.

In addition, under the 2005 Plan, the Board may elect to pay certain consultants, directors, and employees in common stock. The 2005 Plan was amended in
September 2007 to increase the number of options available under the plan to 1,000,000, in 2010 to increase the number of shares under the plan to 1,750,000
and  again  in  2013  to  increase  the  number  shares  available  under  the  plan  to  3,000,000. The  2015  Plan  was  approved  in  June  2015  with  3,000,000  shares
available under the plan.

As  of  December  31,  2015,  there  were  2,082,199  options  exercisable  with  a  weighted  average  exercise  price  of  $2.33,  a  weighted  average  remaining
contractual term of 7.28 years and an intrinsic value of $256,347. The intrinsic value of options exercised during the years ended December 31, 2015 and
2014  was  $18,181  and  $47,241,  respectively.  As  of  December  31,  2015,  there  were  2,768,612  options  outstanding  and  expected  to  vest  with  a  weighted
average exercise price of $2.13, weighted average remaining term of 7.28 years and an intrinsic value of $257,369. The aggregate intrinsic value represents
the total pre-tax intrinsic value (the difference between the closing price of our common stock on the last trading day on December 31, 2015 and the exercise
price, multiplied by the number of in-the-money options) what would have been received by the option holders had all option holders exercised their options
on December 31, 2015. This amount changes based on the fair market value of our common stock.

The  Company  awarded  605,340  and  637,495  stock  options  to  new  employees  and  existing  Board  members  during  the  years  ended  2015  and  2014,
respectively. During the year ended 2015, under the 2005 Equity Incentive Plan, 29,000 option grants were issued to employees and 99,340 option grants
were issued to Board members, and under the 2015 Equity Incentive Plan 477,000 option grants were issued to employees.

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 10. Commitments and Contingencies

The  Company  has  commitments  of  approximately  $500,000  at  December  31,  2015  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. As of December 31, 2015 no milestones or royalty payments have been paid or accrued.

In  December  2014,  the  Company  entered  into  a  lease  agreement  through  May  31,  2018  for  existing  and  expanded  office  space.  The  rent  for  the  first  12
months  was  approximately  $12,300  per  month,  or  approximately  $20.85  per  square  foot.  This  rent  increased  to  approximately  $12,375  per  month,  or
approximately $20.95 per square foot, for the next 12 months and will increase to approximately $12,460 per month, or approximately $21.13 per square foot
for the remainder of the lease. The Company paid rent expense in the amount of $142,935 and $94,400 for 2015 and 2014, respectively.

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  $250,000  in  cash  and  issued  1,849,113  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  that  Hy  BioPharma’s
ownership is not to exceed 19.9% of the Company’s outstanding stock. As of December 31, 2015, no milestone payments have been paid or accrued.

In February 2007, the Company’s Board of Directors authorized the issuance of 50,000 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:

The Company entered into a purchase agreement with Lincoln Park on March 22, 2016 pursuant to which Lincoln Park has committed to purchase up to $12
million of the Company’s common stock.  Concurrently with the execution of the purchase agreement, the Company issued 100,000 shares of its common
stock to Lincoln Park as a partial fee for its commitment to purchase shares of the Company’s common stock under the purchase agreement. The shares that
may  be  sold  pursuant  to  the  purchase  agreement  may  be  sold  by  the  Company  to  Lincoln  Park  at  the  Company’s  discretion  from  time  to  time  over  the
remaining term of approximately 36 months, once the registration statement registering the resale of the shares of common stock sold to Lincoln Park under
the purchase agreement is declared effective by the SEC.  The purchase price for the shares that the Company may sell to Lincoln Park under the purchase
agreement will fluctuate based on the price of the Company’s common stock.  

The Company has the right to control the timing and amount of any sales of its shares to Lincoln Park, except that, pursuant to the terms of the agreements
with Lincoln Park, the Company would be unable to sell shares to Lincoln Park that would cause Lincoln Park to beneficially own more than 4.99% of the
Company’s issued and outstanding common stock.  Sales of the Company’s common stock, if any, to Lincoln Park will depend upon market conditions and
other factors to be determined by the Company.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders
Soligenix, Inc.

We have audited the accompanying consolidated balance sheets of Soligenix, Inc. and subsidiaries (the “Company”) as of December 31, 2015 and 2014, and
the related consolidated statements of operations, shareholders’ deficiency, and cash flows for each of the years then ended. The financial statements are the
responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not
required  to  have,  nor  were  we  engaged  to  perform,  an  audit  of  its  internal  control  over  financial  reporting.  Our  audits  included  consideration  of  internal
control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, 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.  An  audit  includes
examining,  on  a  test  basis,  evidence  supporting  the  amounts  and  disclosures  in  the  financial  statements.  An  audit  also  includes  assessing  the  accounting
principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In  our  opinion,  the  financial  statements  referred  to  above  present  fairly,  in  all  material  respects,  the  consolidated  financial  position  of  Soligenix,  Inc.  and
subsidiaries  as  of  December  31,  2015  and  2014,  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.

2. PURCHASE OF COMMON STOCK.

Subject to the terms and conditions set forth in this Agreement, the Company has the right to sell to the Investor, and the Investor has the obligation

to purchase from the Company, Purchase Shares as follows:

(a)  Commencement  of  Regular  Sales  of  Common  Stock.  Upon  the  satisfaction  of  the  conditions  set  forth  in  Sections  7  and  8  hereof  (the
“Commencement” and the date of satisfaction of such conditions the “Commencement Date”) and thereafter, the Company shall have the right, but not the
obligation, to direct the Investor, by its delivery to the Investor of a Regular Purchase Notice from time to time, to purchase up to One Hundred Thousand
(100,000) Purchase Shares (each such purchase a “Regular Purchase”), at the Purchase Price on the Purchase Date; provided, however, that (i) the Regular
Purchase may be increased to up to One Hundred Fifty Thousand (150,000) Purchase Shares, provided that the Closing Sale Price of the Common Stock is
not below $1.00 on the Purchase Date, (ii) the Regular Purchase may be increased to up to Two Hundred Thousand (200,000) Purchase Shares, provided that
the Closing Sale Price of the Common Stock is not below $1.50 on the Purchase Date, and (iii) the Regular Purchase may be increased to up to Two Hundred
Fifty Thousand (250,000) Purchase Shares, provided that the Closing Sale Price of the Common Stock is not below $2.00 on the Purchase Date (all of which
share and dollar amounts shall be appropriately adjusted for any reorganization, recapitalization, non-cash dividend (excluding dividends of rights and shares
of  capital  stock  issuable  upon  exercise  of  such  rights),  stock  split  or  other  similar  transaction);  provided, further, however,  that  the  Investor’s  committed
obligation  under  any  single  Regular  Purchase  shall  not  exceed  Seven  Hundred  Fifty  Thousand  Dollars  ($750,000).  If  the  Company  delivers  any  Regular
Purchase Notice for a Purchase Amount in excess of the limitations contained in the immediately preceding sentence, such Regular Purchase Notice shall be
void ab initio to the extent of the amount by which the amount of Purchase Shares set forth in such Regular Purchase Notice exceeds the amount of Purchase
Shares which the Company is permitted to include in such Purchase Notice in accordance herewith, and the Investor shall have no obligation to purchase such
excess Purchase Shares in respect of such Regular Purchase Notice; provided that the Investor shall remain obligated to purchase the amount of Purchase
Shares which the Company is permitted to include in such Regular Purchase Notice. The Company may deliver multiple Regular Purchase Notices to the
Investor  so  long  as  at  least  one  (1)  Business  Day  has  passed  since  the  most  recent  Regular  Purchase  was  completed.  Notwithstanding  the  foregoing,  the
Company shall not deliver any Regular Purchase Notices during the PEA Period.

(b)  Accelerated  Purchases.  Subject  to  the  terms  and  conditions  of  this  Agreement,  in  addition  to  purchases  of  Purchase  Shares  as  described  in
Section 2(a)  above,  the  Company  shall  also  have  the  right,  but  not  the  obligation,  to  direct  the  Investor  by  the  Company’s  delivery  to  the  Investor  of  an
Accelerated Purchase Notice from time to time, and the Investor thereupon shall have the obligation, to buy Purchase Shares at the Accelerated Purchase
Price on the Accelerated Purchase Date in an amount equal to the Accelerated Purchase Share Amount (each such purchase, an “Accelerated Purchase”). The
Company may deliver an Accelerated Purchase Notice to the Investor only on a Purchase Date on which the Company also properly submitted a Regular
Purchase Notice for a Regular Purchase and the Closing Sale Price is not below $0.75 (to be appropriately adjusted for any reorganization, recapitalization,
non-cash  dividend,  stock  split  or  other  similar  transaction  and,  effective  upon  the  consummation  of  any  such  reorganization,  recapitalization,  non-cash
dividend,  stock  split  or  other  similar  transaction,  the  Closing  Sale  Price  is  not  below  the  lower  of  (i)  the  adjusted  price  and  (ii)  $0.75).  If  the  Company
delivers any Accelerated Purchase Notice for an Accelerated Purchase Share Amount in excess of the limitations contained in the definition of Accelerated
Purchase Share Amount, such Accelerated Purchase Notice shall be void ab initio to the extent of the amount by which the number of Purchase Shares set
forth in such Accelerated Purchase Notice exceeds the Accelerated Purchase Share Amount which the Company is permitted to include in such Accelerated
Purchase Notice in accordance herewith (which shall be confirmed in an Accelerated Purchase Confirmation (defined below)), and the Investor shall have no
obligation  to  purchase  such  excess  Purchase  Shares  in  respect  of  such  Accelerated  Purchase  Notice;  provided  that  the  Investor  shall  remain  obligated  to
purchase the Accelerated Purchase Share Amount which the Company is permitted to include in such Accelerated Purchase Notice. Upon completion of each
Accelerated Purchase Date, the Accelerated Purchase Share Amount and the applicable Accelerated Purchase Price shall be set forth on a confirmation of the
Accelerated Purchase to be provided to the Company by the Investor (an “Accelerated Purchase Confirmation”).

(c) Payment for Purchase Shares. For each Regular Purchase, the Investor shall pay to the Company an amount equal to the Purchase Amount with
respect to such Regular Purchase as full payment for such Purchase Shares via wire transfer of immediately available funds on the same Business Day that the
Investor receives such Purchase Shares, if such Purchase Shares are received by the Investor before 1:00 p.m., Eastern time, or, if such Purchase Shares are
received  by  the  Investor  after  1:00  p.m.,  Eastern  time,  the  next  Business  Day.  For  each  Accelerated  Purchase,  the  Investor  shall  pay  to  the  Company  an
amount equal to the Purchase Amount with respect to such Accelerated Purchase as full payment for such Purchase Shares via wire transfer of immediately
available funds on the third Business Day following the date that the Investor receives such Purchase Shares. If the Company or the Transfer Agent shall fail
for any reason or for no reason to electronically transfer any Purchase Shares as DWAC Shares in respect of a Regular Purchase or Accelerated Purchase (as
applicable) within five (5) Business Days following the receipt by the Company of the Purchase Price or Accelerated Purchase Price, respectively, therefor in
compliance  with  this  Section  2(c),  and  if  on  or  after  such  Business  Day  the  Investor  purchases  (in  an  open  market  transaction  or  otherwise)  shares  of
Common Stock to deliver in satisfaction of a sale by the Investor of such Purchase Shares that the Investor anticipated receiving from the Company in respect
of such Regular Purchase or Accelerated Purchase (as applicable), then the Company shall, within five (5) Business Days after the Investor’s request, either
(i) pay cash to the Investor in an amount equal to the Investor’s total purchase price (including brokerage commissions, if any) for the shares of Common
Stock so purchased (the “Cover Price”), at which point the Company’s obligation to deliver such Purchase Shares as DWAC Shares shall terminate, or (ii)
promptly honor its obligation to deliver to the Investor such Purchase Shares as DWAC Shares and pay cash to the Investor in an amount equal to the excess
(if any) of the Cover Price over the total Purchase Price for such Regular Purchase plus the total Accelerated Purchase Price for such Accelerated Purchase (as
applicable).  The  Company  shall  not  issue  any  fraction  of  a  share  of  Common  Stock  upon  any  Regular  Purchase  or  Accelerated  Purchase.  If  the  issuance
would result in the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up or down to the
nearest whole share. All payments made under this Agreement shall be made in lawful money of the United States of America or wire transfer of immediately
available funds to such account as the Company may from time to time designate by written notice in accordance with the provisions of this Agreement.
Whenever any amount expressed to be due by the terms of this Agreement is due on any day that is not a Business Day, the same shall instead be due on the
next succeeding day that is a Business Day.

(d) Beneficial Ownership Limitation. Notwithstanding anything to the contrary contained in this Agreement, the Company shall not issue or sell, and
the  Investor  shall  not  purchase  or  acquire,  any  shares  of  Common  Stock  under  this  Agreement  which,  when  aggregated  with  all  other  shares  of  Common
Stock then beneficially owned by the Investor and its affiliates (as calculated pursuant to Section 13(d) of the Exchange Act and Rule 13d-3 promulgated
thereunder),  would  result  in  the  beneficial  ownership  by  the  Investor  and  its  affiliates  of  more  than  4.99%  of  the  then  issued  and  outstanding  shares  of
Common Stock (the “Beneficial Ownership Limitation”). Upon the written or oral request of the Investor, the Company shall promptly (but not later than 24
hours)  confirm  orally  or  in  writing  to  the  Investor  the  number  of  shares  of  Common  Stock  then  outstanding.  The  Investor  and  the  Company  shall  each
cooperate  in  good  faith  in  the  determinations  required  hereby  and  the  application  hereof.  The  Investor’s  written  certification  to  the  Company  of  the
applicability  of  the  Beneficial  Ownership  Limitation,  and  the  resulting  effect  thereof  hereunder  at  any  time,  shall  be  conclusive  with  respect  to  the
applicability thereof and such result absent manifest error.

authorities passed upon or endorsed the merits of the offering of the Securities.

(e) No Conflicts. The execution, delivery and performance of the Transaction Documents by the Company and the consummation by the Company
of the transactions contemplated hereby and thereby (including, without limitation, the reservation for issuance and issuance of the Purchase Shares and the
Commitment  Shares)  will  not  (i)  result  in  a  violation  of  the  Certificate  of  Incorporation,  any  Certificate  of  Designations,  Preferences  and  Rights  of  any
outstanding series of preferred stock of the Company or the Bylaws or (ii) conflict with, or constitute a default (or an event which with notice or lapse of time
or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or
instrument to which the Company or any of its Subsidiaries is a party, or result in a violation of any law, rule, regulation, order, judgment or decree (including
federal and state securities laws and regulations and the rules and regulations of the Principal Market applicable to the Company or any of its Subsidiaries) or
by  which  any  property  or  asset  of  the  Company  or  any  of  its  Subsidiaries  is  bound  or  affected,  except  in  the  case  of  conflicts,  defaults,  terminations,
amendments,  accelerations,  cancellations  and  violations  under  clause  (ii),  which  could  not  reasonably  be  expected  to  result  in  a  Material  Adverse  Effect.
Neither the Company nor its Subsidiaries is in violation of any term of or in default under its Certificate of Incorporation, any Certificate of Designation,
Preferences and Rights of any outstanding series of preferred stock of the Company or Bylaws or their organizational charter or bylaws, respectively. Neither
the  Company  nor  any  of  its  Subsidiaries  is  in  violation  of  any  term  of  or  is  in  default  under  any  material  contract,  agreement,  mortgage,  indebtedness,
indenture, instrument, judgment, decree or order or any statute, rule or regulation applicable to the Company or its Subsidiaries, except for possible conflicts,
defaults,  terminations  or  amendments  that  could  not  reasonably  be  expected  to  have  a  Material  Adverse  Effect.  The  business  of  the  Company  and  its
Subsidiaries is not being conducted, and shall not be conducted, in violation of any law, ordinance, regulation of any governmental entity, except for possible
violations,  the  sanctions  for  which  either  individually  or  in  the  aggregate  could  not  reasonably  be  expected  to  have  a  Material  Adverse  Effect.  Except  as
specifically contemplated by this Agreement and as required under the Securities Act or applicable state securities laws and the rules and regulations of the
Principal  Market,  the  Company  is  not  required  to  obtain  any  consent,  authorization  or  order  of,  or  make  any  filing  or  registration  with,  any  court  or
governmental agency or any regulatory or self-regulatory agency in order for it to execute, deliver or perform any of its obligations under or contemplated by
the  Transaction  Documents  in  accordance  with  the  terms  hereof  or  thereof.  Except  as  set  forth  elsewhere  in  this  Agreement,  all  consents,  authorizations,
orders, filings and registrations which the Company is required to obtain pursuant to the preceding sentence shall be obtained or effected on or prior to the
Commencement  Date.  Since  one  year  prior  to  the  date  hereof,  the  Company  has  not  received  nor  delivered  any  notices  or  correspondence  from  or  to  the
Principal Market. The Principal Market has not commenced any delisting proceedings against the Company.

(f) SEC Documents; Financial Statements. The Company has filed all reports, schedules, forms, statements and other documents required to be filed
by the Company under the Securities Act and the Exchange Act, including pursuant to Section 13(a) or 15(d) thereof, for the twelve months preceding the
date hereof (or such shorter period as the Company was required by law or regulation to file such material) (the foregoing materials, including the exhibits
thereto and documents incorporated by reference therein, being collectively referred to herein as the “SEC Documents”) on a timely basis or has received a
valid extension of such time of filing and has filed any such SEC Documents prior to the expiration of any such extension.  As of their respective dates and to
the best of the Company’s knowledge, the SEC Documents complied in all material respects with the requirements of the Securities Act and the Exchange
Act, as applicable. None of the SEC Documents, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be
stated  therein  or  necessary  in  order  to  make  the  statements  therein,  in  the  light  of  the  circumstances  under  which  they  were  made,  not  misleading.  The
financial statements of the Company included in the SEC Documents comply in all material respects with applicable accounting requirements and the rules
and regulations of the SEC with respect thereto as in effect at the time of filing.  Such financial statements have been prepared in accordance with United
States generally accepted accounting principles applied on a consistent basis during the periods involved (“GAAP”), except as may be otherwise specified in
such  financial  statements  or  the  notes  thereto  and  except  that  unaudited  financial  statements  may  not  contain  all  footnotes  required  by  GAAP,  and  fairly
present  in  all  material  respects  the  financial  position  of  the  Company  and  its  consolidated  Subsidiaries  as  of  and  for  the  dates  thereof  and  the  results  of
operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, immaterial, year-end audit adjustments. Except
as set forth in the SEC Documents, the Company has received no notices or correspondence from the SEC for the one year preceding the date hereof. The
SEC has not commenced any enforcement proceedings against the Company or any of its Subsidiaries.

(g) Absence of Certain Changes. Except as disclosed in the SEC Documents, since December 31, 2014, there has been no material adverse change in
the business, properties, operations, financial condition or results of operations of the Company or its Subsidiaries. The Company has not taken any steps, and
does not currently expect to take any steps, to seek protection pursuant to any Bankruptcy Law nor does the Company or any of its Subsidiaries have any
knowledge or reason to believe that its creditors intend to initiate involuntary bankruptcy or insolvency proceedings. The Company is financially solvent and
is generally able to pay its debts as they become due.

(h) Absence of Litigation. There is no action, suit, proceeding, inquiry or investigation before or by any court, public board, government agency,
self-regulatory organization or body pending or, to the knowledge of the Company or any of its Subsidiaries, threatened against or affecting the Company, the
Common Stock or any of the Company's or its Subsidiaries' officers or directors in their capacities as such, which could reasonably be expected to have a
Material Adverse Effect.

(i) Acknowledgment Regarding Investor's Status. The Company acknowledges and agrees that the Investor is acting solely in the capacity of arm's
length purchaser with respect to the Transaction Documents and the transactions contemplated hereby and thereby. The Company further acknowledges that
the Investor is not acting as a financial advisor or fiduciary of the Company (or in any similar capacity) with respect to the Transaction Documents and the
transactions contemplated hereby and thereby and any advice given by the Investor or any of its representatives or agents in connection with the Transaction
Documents  and  the  transactions  contemplated  hereby  and  thereby  is  merely  incidental  to  the  Investor's  purchase  of  the  Securities.  The  Company  further
represents to the Investor that the Company's decision to enter into the Transaction Documents has been based solely on the independent evaluation by the
Company and its representatives and advisors.

(j) No General Solicitation; No Integrated Offering. Neither the Company, nor any of its affiliates, nor any Person acting on its or their behalf, has
engaged in any form of general solicitation or general advertising (within the meaning of Regulation D under the Securities Act) in connection with the offer
or sale of the Securities. Neither the Company, nor or any of its affiliates, nor any Person acting on their behalf has, directly or indirectly, made any offers or
sales  of  any  security  or  solicited  any  offers  to  buy  any  security,  under  circumstances  that  would  require  registration  of  the  offer  and  sale  of  any  of  the
Securities under the Securities Act, whether through integration with prior offerings or otherwise, or cause this offering of the Securities to be integrated with
prior  offerings  by  the  Company  in  a  manner  that  would  require  stockholder  approval  pursuant  to  the  rules  of  the  Principal  Market  on  which  any  of  the
securities of the Company are listed or designated. The issuance and sale of the Securities hereunder does not contravene the rules and regulations of the
Principal Market.

-11-

 
 
 
 
 
 
 
 
(k) Intellectual Property Rights. The Company and its Subsidiaries own or possess adequate rights or licenses to use all material trademarks, trade
names,  service  marks,  service  mark  registrations,  service  names,  patents,  patent  rights,  copyrights,  inventions,  licenses,  approvals,  governmental
authorizations, trade secrets and rights necessary to conduct their respective businesses as now conducted. None of the Company's material trademarks, trade
names, service marks, service mark registrations, service names, patents, patent rights, copyrights, inventions, licenses, approvals, government authorizations,
trade secrets or other intellectual property rights have expired or terminated, or, by the terms and conditions thereof, could expire or terminate within two
years from the date of this Agreement. The Company and its Subsidiaries do not have any knowledge of any infringement by the Company or its Subsidiaries
of any material trademark, trade name rights, patents, patent rights, copyrights, inventions, licenses, service names, service marks, service mark registrations,
trade secret or other similar rights of others, or of any such development of similar or identical trade secrets or technical information by others, and there is no
claim,  action  or  proceeding  being  made  or  brought  against,  or  to  the  Company's  knowledge,  being  threatened  against,  the  Company  or  its  Subsidiaries
regarding trademark, trade name, patents, patent rights, invention, copyright, license, service names, service marks, service mark registrations, trade secret or
other infringement, which could reasonably be expected to have a Material Adverse Effect.

(l) Environmental Laws. The Company and its Subsidiaries (i) are in compliance with any and all applicable foreign, federal, state and local laws and
regulations  relating  to  the  protection  of  human  health  and  safety,  the  environment  or  hazardous  or  toxic  substances  or  wastes,  pollutants  or  contaminants
(“Environmental Laws”), (ii) have received all permits, licenses or other approvals required of them under applicable Environmental Laws to conduct their
respective businesses and (iii) are in compliance with all terms and conditions of any such permit, license or approval, except where, in each of the three
foregoing clauses, the failure to so comply could not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(m)  Title.  The  Company  and  its  Subsidiaries  have  good  and  marketable  title  in  fee  simple  to  all  real  property  owned  by  them  and  good  and
marketable title in all personal property owned by them that is material to the business of the Company and its Subsidiaries, in each case free and clear of all
liens, encumbrances and defects (“Liens”) and, except for Liens as do not materially affect the value of such property and do not materially interfere with the
use  made  and  proposed  to  be  made  of  such  property  by  the  Company  and  its  Subsidiaries  and  Liens  for  the  payment  of  federal,  state  or  other  taxes,  the
payment of which is neither delinquent nor subject to penalties.  Any real property and facilities held under lease by the Company and its Subsidiaries are held
by  them  under  valid,  subsisting  and  enforceable  leases  with  which  the  Company  and  its  Subsidiaries  are  in  compliance  with  such  exceptions  as  are  not
material and do not interfere with the use made and proposed to be made of such property and buildings by the Company and its Subsidiaries.

(n) Insurance. The Company and each of its Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks
and in such amounts as management of the Company believes to be prudent and customary in the businesses in which the Company and its Subsidiaries are
engaged. Neither the Company nor any such Subsidiary has been refused any insurance coverage sought or applied for and neither the Company nor any such
Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar
coverage from similar insurers as may be necessary to continue its business at a cost that would not materially and adversely affect the condition, financial or
otherwise, or the earnings, business or operations of the Company and its Subsidiaries, taken as a whole.

(o) Regulatory Permits.  The  Company  and  its  Subsidiaries  possess  all  material  certificates,  authorizations  and  permits  issued  by  the  appropriate
federal, state or foreign regulatory authorities necessary to conduct their respective businesses, and neither the Company nor any such Subsidiary has received
any notice of proceedings relating to the revocation or modification of any such certificate, authorization or permit.

-12-

 
 
 
 
 
 
 
 
 
(p) Tax Status. The Company and each of its Subsidiaries has made or filed all federal and state income and all other material tax returns, reports and
declarations required by any jurisdiction to which it is subject (unless and only to the extent that the Company and each of its Subsidiaries has set aside on its
books provisions reasonably adequate for the payment of all unpaid and unreported taxes) and has paid all taxes and other governmental assessments and
charges that are material in amount, shown or determined to be due on such returns, reports and declarations, except those being contested in good faith and
has set aside on its books provision reasonably adequate for the payment of all taxes for periods subsequent to the periods to which such returns, reports or
declarations apply. There are no unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the
Company know of no basis for any such claim.

(q) Transactions With Affiliates.  Except as set forth in the SEC Documents, none of the officers or directors of the Company and, to the knowledge
of the Company, none of the employees of the Company is presently a party to any transaction with the Company or any Subsidiary (other than for services as
employees, officers and directors), including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing for
rental of real or personal property to or from, or otherwise requiring payments to or from any officer, director or such employee or, to the knowledge of the
Company, any entity in which any officer, director, or any such employee has a substantial interest or is an officer, director, trustee or partner, in each case in
excess of $120,000 other than for (i) payment of salary or consulting fees for services rendered, (ii) reimbursement for expenses incurred on behalf of the
Company and (iii) other employee benefits, including stock option agreements under any stock option plan of the Company.

(r)  Application  of  Takeover  Protections.  The  Company  and  its  board  of  directors  have  taken  or  will  take  prior  to  the  Commencement  Date  all

draft version of the Current Report within one (1) Business Day from the date the Investor receives it from the Company.

(i)  the  issuance  of  the  Commitment  Shares  and  the  sale  of  the  Purchase  Shares  to  the  Investor  under  this  Agreement  and  (ii)  any  subsequent  resale  of  all
Commitment Shares and all Purchase Shares by the Investor, in each case, under applicable securities or “Blue Sky” laws of the states of the United States in
such states as is reasonably requested by the Investor from time to time, and shall provide evidence of any such action so taken to the Investor.

such listing of all such Securities from time to time issuable hereunder. The Company shall use reasonable best efforts to maintain the listing of the Common
Stock  on  the  Principal  Market  and  shall  comply  in  all  respects  with  the  Company’s  reporting,  filing  and  other  obligations  under  the  bylaws  or  rules  and
regulations of the Principal Market. Neither the Company nor any of its Subsidiaries shall take any action that would reasonably be expected to result in the

recapitalization, non-cash dividend, stock split or other similar transaction. For the avoidance of doubt, (1) all of the Initial Commitment Shares shall be fully
earned  as  of  the  date  of  this  Agreement,  whether  or  not  the  Commencement  shall  occur  or  any  Purchase  Shares  are  purchased  by  the  Investor  under  this
Agreement and irrespective of any subsequent termination of this Agreement and (2) the Additional Commitment Shares shall be fully earned as of the date
of their issuance pursuant to this Agreement, irrespective of any subsequent termination of this Agreement.

(f) Due Diligence; Non-Public Information. The Investor shall have the right, from time to time as the Investor may reasonably deem appropriate, to
perform reasonable due diligence on the Company during normal business hours. The Company and its officers and employees shall provide information and
reasonably cooperate with the Investor in connection with any reasonable request by the Investor related to the Investor's due diligence of the Company. Each
party hereto agrees not to disclose any Confidential Information of the other party to any third party and shall not use the Confidential Information for any
purpose  other  than  in  connection  with,  or  in  furtherance  of,  the  transactions  contemplated  hereby.  Each  party  hereto  acknowledges  that  the  Confidential
Information shall remain the property of the disclosing party and agrees that it shall take all reasonable measures to protect the secrecy of any Confidential
Information  disclosed  by  the  other  party.  The  Company  confirms  that  neither  it  nor  any  other  Person  acting  on  its  behalf  shall  provide  the  Investor  or  its
agents  or  counsel  with  any  information  that  constitutes  or  might  constitute  material,  non-public  information,  unless  a  simultaneous  public  announcement
thereof is made by the Company in the manner contemplated by Regulation FD. In the event of a breach of the foregoing covenant by the Company or any
Person acting on its behalf (as determined in the reasonable good faith judgment of the Investor), in addition to any other remedy provided herein or in the
other Transaction Documents, the Investor shall have the right to make a public disclosure, in the form of a press release, public advertisement or otherwise,
of such material, non-public information without the prior approval by the Company; provided the Investor shall have first provided notice to the Company
that  it  believes  it  has  received  information  that  constitutes  material,  non-public  information,  the  Company  shall  have  at  least  24  hours  to  respond  to  such
notice, and thereafter the Investor shall have provided a draft final version of such press release, public advertisement or otherwise at least 24 hours prior to
the  Investor’s  intended  public  disclosure,  and  the  Investor  shall  have  incorporated  any  reasonable  comments  made  by  the  Company  on  such  draft  press
release, and the Company shall have failed to publicly disclose such material, non-public information prior to such disclosure by the Investor. The Investor
shall not have any liability to the Company, any of its Subsidiaries, or any of their respective directors, officers, employees, stockholders or agents, for any
such disclosure. The Company understands and confirms that the Investor shall be relying on the foregoing covenants in effecting transactions in securities of
the Company.

obligations  under  the  Transaction  Documents,  including,  without  limitation,  the  obligation  of  the  Company  to  deliver  the  Purchase  Shares  and  the

Equivalents at a future determined price. “Exempt Issuance” means the issuance of (a) Common Stock or options to employees, officers, directors or vendors

company  or  an  asset  in  a  business  synergistic  with  the  business  of  the  Company  and  shall  provide  to  the  Company  additional  benefits  in  addition  to  the
investment of funds, but shall not include a transaction in which the Company is issuing securities primarily for the purpose of raising capital or to an entity
whose primary business is investing in securities; and (d) Common Stock issued and sold pursuant to an “at-the-market offering” of Common Stock through a

prevent or change the transactions contemplated by the Transaction Documents, or seeking material damages in connection with such transactions.

9. INDEMNIFICATION.

In consideration of the Investor's execution and delivery of the Transaction Documents and acquiring the Securities hereunder and in addition to all
of the Company's other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and hold harmless the Investor and all of
its  affiliates,  stockholders,  officers,  directors,  employees  and  direct  or  indirect  investors  and  any  of  the  foregoing  Person's  agents  or  other  representatives
(including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the "Indemnitees") from and
against  any  and  all  actions,  causes  of  action,  suits,  claims,  losses,  costs,  penalties,  fees,  liabilities  and  damages,  and  expenses  in  connection  therewith
(irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys' fees
and disbursements (the "Indemnified Liabilities"),  incurred  by  any  Indemnitee  as  a  result  of,  or  arising  out  of,  or  relating  to  (a)  any  misrepresentation  or
breach of any representation or warranty made by the Company in the Transaction Documents or any other certificate, instrument or document contemplated
hereby or thereby, (b) any breach of any covenant, agreement or obligation of the Company contained in the Transaction Documents or any other certificate,
instrument or document contemplated hereby or thereby, or (c) any cause of action, suit or claim brought or made against such Indemnitee and arising out of
or  resulting  from  the  execution,  delivery,  performance  or  enforcement  of  the  Transaction  Documents  or  any  other  certificate,  instrument  or  document
contemplated hereby or thereby, other than, in the case of clause (c), with respect to Indemnified Liabilities which directly and primarily result from the fraud,
gross negligence or willful misconduct of an Indemnitee. The indemnity in this Section 9 shall not apply to amounts paid in settlement of any claim if such
settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed. To the
extent  that  the  foregoing  undertaking  by  the  Company  may  be  unenforceable  for  any  reason,  the  Company  shall  make  the  maximum  contribution  to  the
payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. Payment under this indemnification shall be made
within thirty (30) days from the date Investor makes written request for it. A certificate containing reasonable detail as to the amount of such indemnification
submitted to the Company by Investor shall be conclusive evidence, absent manifest error, of the amount due from the Company to Investor. If any action
shall be brought against any Indemnitee in respect of which indemnity may be sought pursuant to this Agreement, such Indemnitee shall promptly notify the
Company  in  writing,  and  the  Company  shall  have  the  right  to  assume  the  defense  thereof  with  counsel  of  its  own  choosing  reasonably  acceptable  to  the
Indemnitee.  Any  Indemnitee  shall  have  the  right  to  employ  separate  counsel  in  any  such  action  and  participate  in  the  defense  thereof,  but  the  fees  and
expenses of such counsel shall be at the expense of such Indemnitee, except to the extent that (i) the employment thereof has been specifically authorized by
the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (iii) in such action
there is, in the reasonable opinion of such separate counsel, a material conflict on any material issue between the position of the Company and the position of
such Indemnitee, in which case the Company shall be responsible for the reasonable fees and expenses of no more than one such separate counsel.

10. EVENTS OF DEFAULT.

An "Event of Default" shall be deemed to have occurred at any time as any of the following events occurs:

(a)  the  effectiveness  of  a  registration  statement  registering  the  resale  of  the  Securities  lapses  for  any  reason  (including,  without  limitation,  the
issuance of a stop order or similar order) or such registration statement (or the prospectus forming a part thereof) is unavailable to the Investor for resale of
any or all of the Securities to be issued to the Investor under the Transaction Documents, and such lapse or unavailability continues for a period of ten (10)
consecutive Business Days or for more than an aggregate of thirty (30) Business Days in any 365-day period, but excluding a lapse or unavailability where (i)
the Company terminates a registration statement after the Investor has confirmed in writing that all of the Securities covered thereby have been resold or (ii)
the  Company  supersedes  one  registration  statement  with  another  registration  statement,  including  (without  limitation)  by  terminating  a  prior  registration
statement when it is effectively replaced with a new registration statement covering Securities (provided in the case of this clause (ii) that all of the Securities
covered by the superseded (or terminated) registration statement that have not theretofore been resold are included in the superseding (or new) registration
statement);

(b) the suspension of the Common Stock from trading on the Principal Market for a period of one (1) Business Day, provided that the Company may

not direct the Investor to purchase any shares of Common Stock during any such suspension;

(c) the delisting of the Common Stock from the OTCQB operated by the OTC Markets Group, Inc., provided, however, that the Common Stock is
not  immediately  thereafter  trading  on  the  New  York  Stock  Exchange,  the  NYSE  MKT,  the  NYSE  Arca,  The  NASDAQ  Capital  Market,  The  NASDAQ
Global  Market,  The  NASDAQ  Global  Select  Market,  the  OTC  Bulletin  Board  or  the  OTCQX  operated  by  the  OTC  Markets  Group,  Inc.  (or  nationally
recognized successor to any of the foregoing);

(d) the failure for any reason by the Transfer Agent to issue (i) the Additional Commitment Shares to the Investor within five (5) Business Days after
the  date  on  which  the  Investor  is  entitled  to  receive  such  Additional  Commitment  Shares  pursuant  to  Section  5(e)  hereof  and  (ii)  Purchase  Shares  to  the
Investor within five (5) Business Days after the applicable Purchase Date or Accelerated Purchase Date (as applicable) on which the Investor is entitled to
receive such Purchase Shares;

(e) the Company breaches any representation, warranty, covenant or other term or condition under any Transaction Document if such breach could
have a Material Adverse Effect and except, in the case of a breach of a covenant which is reasonably curable, only if such breach continues for a period of at
least five (5) Business Days;

(f) if any Person commences a proceeding against the Company pursuant to or within the meaning of any Bankruptcy Law;

-23-

 
 
 
 
 
 
 
 
 
 
 
 
(g) if the Company, pursuant to or within the meaning of any Bankruptcy Law, (i) commences a voluntary case, (ii) consents to the entry of an order
for relief against it in an involuntary case, (iii) consents to the appointment of a Custodian of it or for all or substantially all of its property, or (iv) makes a
general assignment for the benefit of its creditors or is generally unable to pay its debts as the same become due;

(h) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that (i) is for relief against the Company in an involuntary
case, (ii) appoints a Custodian of the Company or for all or substantially all of its property, or (iii) orders the liquidation of the Company or any Subsidiary; or

(i) if at any time the Company is not eligible to transfer its Common Stock electronically as DWAC Shares.

In addition to any other rights and remedies under applicable law and this Agreement, so long as an Event of Default has occurred and is continuing, or if any
event  which,  after  notice  and/or  lapse  of  time,  would  become  an  Event  of  Default,  has  occurred  and  is  continuing,  the  Company  shall  not  deliver  to  the
Investor any Regular Purchase Notice or Accelerated Purchase Notice.

11. TERMINATION

This Agreement may be terminated only as follows:

(a) If pursuant to or within the meaning of any Bankruptcy Law, the Company commences a voluntary case or any Person commences a proceeding
against the Company, which is not discharged within 90 days, a Custodian is appointed for the Company or for all or substantially all of its property, or the
Company makes a general assignment for the benefit of its creditors (any of which would be an Event of Default as described in Sections 10(f), 10(g) and
10(h) hereof), this Agreement shall automatically terminate without any liability or payment to the Company (except as set forth below) without further action
or notice by any Person.

(b) In the event that the Commencement shall not have occurred on or before July 15, 2016, due to the failure to satisfy the conditions set forth in
Sections 7  and  8  above  with  respect  to  the  Commencement,  this  Agreement  may  be  terminated  by  either  party  at  the  close  of  business  on  such  date  or
thereafter without liability of such party to the other party (except as set forth below); provided, however, that the right to terminate this Agreement under this
Section  11(b)  shall  not  be  available  to  any  party  if  such  party  is  then  in  breach  of  any  covenant  or  agreement  contained  in  this  Agreement  or  any
representation or warranty of such party contained in this Agreement fails to be true and correct such that the conditions set forth in Section 7(c) or Section
8(e), as applicable, could not then be satisfied.

(c) At any time after the Commencement Date, the Company shall have the option to terminate this Agreement for any reason or for no reason by
delivering notice (a “Company Termination Notice”) to the Investor electing to terminate this Agreement without any liability whatsoever of any party to any
other party under this Agreement (except as set forth below). The Company Termination Notice shall not be effective until one (1) Business Day after it has
been received by the Investor.

(d)  This  Agreement  shall  automatically  terminate  on  the  date  that  the  Company  sells  and  the  Investor  purchases  the  full  Available  Amount  as
provided  herein,  without  any  action  or  notice  on  the  part  of  any  party  and  without  any  liability  whatsoever  of  any  party  to  any  other  party  under  this
Agreement (except as set forth below).

(e) If, for any reason or for no reason, the full Available Amount has not been purchased in accordance with Section 2 of this Agreement by the
Maturity  Date,  this  Agreement  shall  automatically  terminate  on  the  Maturity  Date,  without  any  action  or  notice  on  the  part  of  any  party  and  without  any
liability whatsoever of any party to any other party under this Agreement (except as set forth below).

-24-

 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
Except  as  set  forth  in  Sections 11(a)  (in  respect  of  an  Event  of  Default  under  Sections 10(f),  10(g)  and  10(h)),  11(d)  and  11(e),  any  termination  of  this
Agreement pursuant to this Section 11 shall be effected by written notice from the Company to the Investor, or the Investor to the Company, as the case may
be, setting forth the basis for the termination hereof. The representations and warranties and covenants of the Company and the Investor contained in Sections
3, 4, 5, and 6 hereof, the indemnification provisions set forth in Section 9 hereof and the agreements and covenants set forth in Sections 10, 11 and 12 shall
survive the Commencement and any termination of this Agreement. No termination of this Agreement shall (i) affect the Company’s or the Investor’s rights
or  obligations  under  (A)  this  Agreement  with  respect  to  pending  Regular  Purchases  and  Accelerated  Purchases  and  the  Company  and  the  Investor  shall
complete  their  respective  obligations  with  respect  to  any  pending  Regular  Purchases  and  Accelerated  Purchases  under  this  Agreement  and  (B)  the
Registration Rights Agreement, which shall survive any such termination, or (ii) be deemed to release the Company or the Investor from any liability for
intentional misrepresentation or willful breach of any of the Transaction Documents.

12. MISCELLANEOUS.

Company  and  its  stockholders.  All  other  questions  concerning  the  construction,  validity,  enforcement  and  interpretation  of  this  Agreement  and  the  other
Transaction Documents shall be governed by the internal laws of the State of Illinois, without giving effect to any choice of law or conflict of law provision or
rule (whether of the State of Illinois or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of Illinois.
Each  party  hereby  irrevocably  submits  to  the  exclusive  jurisdiction  of  the  state  and  federal  courts  sitting  in  the  State  of  Illinois,  County  of  Cook,  for  the

to  the  jurisdiction  of  any  such  court,  that  such  suit,  action  or  proceeding  is  brought  in  an  inconvenient  forum  or  that  the  venue  of  such  suit,  action  or
proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or
proceeding by mailing a copy thereof to such party at the address for such notices to it under this Agreement and agrees that such service shall constitute good
and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner
permitted by law. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY
TRIAL  FOR  THE  ADJUDICATION  OF  ANY  DISPUTE  HEREUNDER  OR  IN  CONNECTION  HEREWITH  OR  ARISING  OUT  OF  THIS
AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

(b)  Counterparts.  This  Agreement  may  be  executed  in  two  or  more  identical  counterparts,  all  of  which  shall  be  considered  one  and  the  same
agreement and shall become effective when counterparts have been signed by each party and delivered to the other party; provided that a facsimile signature
or signature delivered by e-mail in a “.pdf” format data file shall be considered due execution and shall be binding upon the signatory thereto with the same
force and effect as if the signature were an original signature.

(c)  Headings.  The  headings  of  this  Agreement  are  for  convenience  of  reference  and  shall  not  form  part  of,  or  affect  the  interpretation  of,  this

Agreement.

(d) Severability. If any provision of this Agreement shall be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not
affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of any provision of this Agreement
in any other jurisdiction.

(e) Entire Agreement.  The  Transaction  Documents  supersede  all  other  prior  oral  or  written  agreements  between  the  Investor,  the  Company,  their
affiliates  and  Persons  acting  on  their  behalf  with  respect  to  the  subject  matter  thereof,  and  this  Agreement,  the  other  Transaction  Documents  and  the
instruments referenced herein contain the entire understanding of the parties with respect to the matters covered herein and therein and, except as specifically
set forth herein or therein, neither the Company nor the Investor makes any representation, warranty, covenant or undertaking with respect to such matters.
The Company acknowledges and agrees that is has not relied on, in any manner whatsoever, any representations or statements, written or oral, other than as
expressly set forth in the Transaction Documents.

(k) No  Financial  Advisor,  Placement  Agent,  Broker  or  Finder.  The  Company  represents  and  warrants  to  the  Investor  that,  except  as  disclosed  in

of compliance with the provisions giving rise to such remedy and nothing herein shall limit the Investor's right to pursue actual damages for any failure by the
Company to comply with the terms of this Agreement. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable
harm to the Investor and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or
threatened breach, the Investor shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of
showing economic loss and without any bond or other security being required.

(n) Enforcement Costs. If: (i) this Agreement is placed by the Investor in the hands of an attorney for enforcement or is enforced by the Investor

whatsoever in connection with this Agreement, then the Company shall pay to the Investor, as incurred by the Investor, all reasonable costs and expenses
including attorneys' fees incurred in connection therewith, in addition to all other amounts due hereunder. If this Agreement is placed by the Company in the
hands of an attorney for enforcement or is enforced by the Company through any legal proceeding, then the Investor shall pay to the Company, as incurred by
the Company, all reasonable costs and expenses including attorneys' fees incurred in connection therewith, in addition to all other amounts due hereunder.

(o) Amendment and Waiver; Failure or Indulgence Not Waiver. No provision of this Agreement may be amended or waived by the parties from and
after the date that is one (1) Business Day immediately preceding the filing of the initial Registration Statement with the SEC. Subject to the immediately
preceding sentence, (i) no provision of this Agreement may be amended other than by a written instrument signed by both parties hereto and (ii) no provision
of this Agreement may be waived other than in a written instrument signed by the party against whom enforcement of such waiver is sought. No failure or
delay in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power,
right or privilege preclude other or further exercise thereof or of any other right, power or privilege.

FORM OF COMPANY COUNSEL OPINION

Capitalized terms used herein but not defined herein, have the meaning set forth in the Purchase Agreement. Based on the foregoing, and subject to

the assumptions and qualifications set forth herein, we are of the opinion that:

1. The Company is a corporation existing and in good standing under the laws of the State of Delaware. The Company is qualified to do

business as a foreign corporation and is in good standing in the State of New Jersey.

2. The Company has the corporate power to execute and deliver, and perform its obligations under, each Transaction Document to which it

by all necessary corporate action on the part of the Company. The execution and delivery of the Transaction Documents by the Company, the performance of
the obligations of the Company thereunder and the consummation by it of the transactions contemplated therein have been duly authorized and approved by
the Company's Board of Directors and no further consent, approval or authorization of the Company, its Board of Directors or its stockholders is required.
The  Transaction  Documents  to  which  the  Company  is  a  party  have  been  duly  executed  and  delivered  by  the  Company  and  are  the  valid  and  binding
obligations  of  the  Company,  enforceable  against  the  Company  in  accordance  with  their  terms  except  as  such  enforceability  may  be  limited  by  general
principles of equity or applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting creditor’s rights and
remedies.

4.  The  execution,  delivery  and  performance  by  the  Company  of  the  Transaction  Documents,  the  consummation  by  the  Company  of  the
transactions contemplated thereby including the offering, sale and issuance of the Commitment Shares and the Purchase Shares in accordance with the terms
and conditions of the Purchase Agreement, and fulfillment and compliance with terms of the Transaction Documents, does not and shall not: (i) conflict with,
constitute a breach of or default (or an event which, with the giving of notice or lapse of time or both, constitutes or could constitute a breach or a default),
under (a) the Certificate of Incorporation or the Bylaws of the Company, (b) any material agreement, note, lease, mortgage, deed or other material instrument

have been properly reserved for issuance as Additional Commitment Shares under the Purchase Agreement. 5,000,000 shares of Common Stock have been
properly reserved for issuance as Purchase Shares under the Purchase Agreement. When issued in accordance with the Purchase Agreement, the Additional

any other Person for the registration under the Securities Act of any shares of Common Stock or other securities of the Company which have not been waived.

 
 
 
 
 
 
 
 
 
 
6. As of the date hereof, the authorized capital stock of the Company consists of 50,000,000 shares of common stock, par value $0.001 per

offering, sale and issuance of the Commitment Shares and the Purchase Shares to you pursuant to the Transaction Documents is exempt from registration
under the Securities Act.

8. Other than that which has been obtained and completed prior to the date hereof, no authorization, approval, consent, filing or other order
of any federal or state governmental body, regulatory agency, or stock exchange or market, or any court, or, to our knowledge, any third party is required to be
obtained by the Company to enter into and perform its obligations under the Transaction Documents or for the Company to issue and sell the Commitment
Shares and the Purchase Shares as contemplated by the Transaction Documents.

9. The Common Stock is registered pursuant to Section 12(g) of the Exchange Act. To our knowledge, since one year preceding the date of

been in compliance with any of the rules and regulations (including the requirements for continued listing) of the Principal Market.

10. The Company is not, and after giving effect to the issuance of the Commitment Shares and the Purchase Shares and the application of
the  proceeds  as  described  in  the  Prospectus,  will  not  be,  an  “investment  company,”  as  that  term  is  defined  in  the  Investment  Company  Act  of  1940,  as
amended.

11. Except as described in the Registration Statement and the Prospectus or the SEC Documents, none of the Material Agreements grants to
any person the right to require the Company to file a registration statement under the Securities Act with respect to any securities of the Company owned or to
be owned by such person or to require the Company to include such securities in the securities registered pursuant to the Registration Statement or in any
securities being registered pursuant to any other registration statement filed by the Company under the Securities Act.

The  primary  purpose  of  our  professional  engagement  was  not  to  establish  or  confirm  factual  matters  or  financial,  quantitative  ,  statistical  or

Registration Statement, at the effective time thereof (including the Incorporated Documents), contained an untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the statements contained therein not misleading or that the Prospectus (including any
Incorporated Documents), as of its date and as of the date hereof, contained or contains any untrue statement of a material fact or omitted or omits to state any
material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made,
not  misleading  (in  each  case  other  than  the  financial  statements  and  the  related  notes  thereto,  the  financial  statement  schedules  and  the  other  financial,
statistical, quantitative and accounting data included therein or which should be included therein, as to which we express no view). “Primary Lawyer Group”
means any lawyer in this firm who (i) signs this letter on behalf of the firm or (ii) actively renders Legal Services. In connection with delivering this letter, the
lawyers in the Primary Lawyer Group, with your consent, have not made any inquiry of other lawyers practicing law with this firm or any review of files

Further, we confirm to you that the Registration Statement, as of its effective date, and the Prospectus, as of its date, appeared to us on their face to

EXHIBIT 10.32

REGISTRATION RIGHTS AGREEMENT (this "Agreement"), dated as of March 22, 2016, by and between SOLIGENIX, INC., a  Delaware
corporation (the "Company"), and LINCOLN PARK CAPITAL FUND, LLC, an Illinois limited liability company (together with it permitted assigns, the
“Buyer”).  Capitalized  terms  used  herein  and  not  otherwise  defined  herein  shall  have  the  respective  meanings  set  forth  in  the  Purchase  Agreement  by  and
between  the  parties  hereto,  dated  as  of  the  date  hereof  (as  amended,  restated,  supplemented  or  otherwise  modified  from  time  to  time,  the  "Purchase
Agreement").

WHEREAS:

The Company has agreed, upon the terms and subject to the conditions of the Purchase Agreement, to sell to the Buyer up to Twelve Million Dollars
($12,000,000)  of  Purchase  Shares  and  to  induce  the  Buyer  to  enter  into  the  Purchase  Agreement,  the  Company  has  agreed  to  provide  certain  registration
rights under the Securities Act of 1933, as amended, and the rules and regulations thereunder, or any similar successor statute (collectively, the "Securities
Act"), and applicable state securities laws.

NOW, THEREFORE, in consideration of the promises and the mutual covenants contained herein and other good and valuable consideration, the

receipt and sufficiency of which are hereby acknowledged, the Company and the Buyer hereby agree as follows:

1. DEFINITIONS.

As used in this Agreement, the following terms shall have the following meanings:

a. "Investor" means the Buyer, any transferee or assignee thereof to whom a Buyer assigns its rights under this Agreement in accordance
with Section 9 and who agrees to become bound by the provisions of this Agreement, and any transferee or assignee thereof to whom a transferee or assignee
assigns its rights under this Agreement in accordance with Section 9 and who agrees to become bound by the provisions of this Agreement.

b.  "Person"  means  any  individual  or  entity  including  but  not  limited  to  any  corporation,  a  limited  liability  company,  an  association,  a

partnership, an organization, a business, an individual, a governmental or political subdivision thereof or a governmental agency.

c. "Register," "registered," and "registration" refer to a registration effected by preparing and filing one or more registration statements of
the Company in compliance with the Securities Act and pursuant to Rule 415 under the Securities Act or any successor rule providing for offering securities
on  a  continuous  basis  ("Rule 415"),  and  the  declaration  or  ordering  of  effectiveness  of  such  registration  statement(s)  by  the  United  States  Securities  and
Exchange Commission (the "SEC").

d. "Registrable Securities" means all of the Initial Commitment Shares, all of the Additional Commitment Shares and all of the Purchase
Shares that may, from time to time, be issued or become issuable to the Investor under the Purchase Agreement (without regard to any limitation or restriction
on purchases), and any and all shares of capital stock issued or issuable with respect to the Purchase Shares, the Initial Commitment Shares or the Additional
Commitment Shares or the Purchase Agreement as a result of any stock split, stock dividend, recapitalization, exchange or similar event or otherwise, without
regard to any limitation on purchases under the Purchase Agreement.

 
 
 
 
 
 
 
 
 
 
 
 
 
e. "Registration Statement" means one or more registration statements of the Company covering only the sale of the Registrable Securities.

2. REGISTRATION.

a.  Mandatory  Registration.  The  Company  shall,  within  thirty  (30)  calendar  days  after  the  date  hereof,  file  with  the  SEC  an  initial
Registration Statement covering 5,600,000 of the Registrable Securities so as to permit the resale of such Registrable Securities by the Investor under Rule
415  under  the  Securities  Act  at  then  prevailing  market  prices  (and  not  fixed  prices).  The  initial  Registration  Statement  shall  register  only  the  Registrable
Securities. The Investor and its counsel shall have a reasonable opportunity to review and comment upon such Registration Statement and any amendment or
supplement to such Registration Statement and any related prospectus prior to its filing with the SEC, and the Company shall give due consideration to all
such comments. The Investor shall furnish all information reasonably requested by the Company for inclusion therein. The Company shall use its best efforts
to have the Registration Statement and any amendment declared effective by the SEC at the earliest possible date. The Company shall use reasonable best
efforts to keep the Registration Statement effective pursuant to Rule 415 promulgated under the Securities Act and available for the resale by the Investor of
all  of  the  Registrable  Securities  covered  thereby  at  all  times  until  the  date  on  which  the  Investor  shall  have  resold  all  the  Registrable  Securities  covered
thereby and no Available Amount remains under the Purchase Agreement (the "Registration Period"). The Registration Statement (including any amendments
or supplements thereto and prospectuses contained therein) shall not contain any untrue statement of a material fact or omit to state a material fact required to
be stated therein, or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading.

b. Rule 424 Prospectus. The Company shall, as required by applicable securities regulations, from time to time file with the SEC, pursuant
to Rule 424 promulgated under the Securities Act, the prospectus and prospectus supplements, if any, to be used in connection with sales of the Registrable
Securities under the Registration Statement. The Investor and its counsel shall have a reasonable opportunity to review and comment upon such prospectus
prior  to  its  filing  with  the  SEC,  and  the  Company  shall  give  due  consideration  to  all  such  comments.  The  Investor  shall  use  its  reasonable  best  efforts  to
comment upon such prospectus within one (1) Business Day from the date the Investor receives the final pre-filing version of such prospectus.

c. Sufficient Number of Shares Registered. Provided the Company’s Certificate of Amendment, as amended, has been amended to increase
the number of shares of Common Stock, in the event the number of shares available under the Registration Statement is insufficient to cover the Registrable
Securities, as mutually determined by both the Company and the Investor in consultation with their respective legal counsel, the Company shall amend the
Registration Statement or file a new Registration Statement (a ”New Registration Statement”), so as to cover all of such Registrable Securities (subject to the
limitations set forth in Section 2(a)) as soon as practicable, but in any event not later than ten (10) Business Days after the necessity therefor arises, subject to
any limits that may be imposed by the SEC pursuant to Rule 415 under the Securities Act. The Company shall use it reasonable best efforts to cause such
amendment and/or New Registration Statement to become effective as soon as practicable following the filing thereof.

2

 
 
 
 
 
 
 
 
 
d. Offering. If the staff of the SEC (the “Staff”) or the SEC seeks to characterize any offering pursuant to a Registration Statement filed
pursuant  to  this  Agreement  as  constituting  an  offering  of  securities  that  does  not  permit  such  Registration  Statement  to  become  effective  and  be  used  for
resales by the Investor under Rule 415 at then-prevailing market prices (and not fixed prices), or if after the filing of the initial Registration Statement with the
SEC pursuant to Section 2(a), the Company is otherwise required by the Staff or the SEC to reduce the number of Registrable Securities included in such
initial Registration Statement, then the Company shall reduce the number of Registrable Securities to be included in such initial Registration Statement (with
the  prior  consent,  which  shall  not  be  unreasonably  withheld,  of  the  Investor  and  its  legal  counsel  as  to  the  specific  Registrable  Securities  to  be  removed
therefrom) until such time as the Staff and the SEC shall so permit such Registration Statement to become effective and be used as aforesaid. In the event of
any  reduction  in  Registrable  Securities  pursuant  to  this  paragraph,  the  Company  shall  file  one  or  more  New  Registration  Statements  in  accordance  with
Section 2(c) until such time as all Registrable Securities have been included in Registration Statements that have been declared effective and the prospectus
contained therein is available for use by the Investor. Notwithstanding any provision herein or in the Purchase Agreement to the contrary, the Company’s
obligations to register Registrable Securities (and any related conditions to the Investor’s obligations) shall be qualified as necessary to comport with any
requirement of the SEC or the Staff as addressed in this Section 2(d).

3. RELATED OBLIGATIONS.

With respect to the Registration Statement and whenever any Registrable Securities are to be registered pursuant to Section 2 including on any New
Registration  Statement,  the  Company  shall  use  its  reasonable  best  efforts  to  effect  the  registration  of  the  Registrable  Securities  in  accordance  with  the
intended method of disposition thereof and, pursuant thereto, the Company shall have the following obligations:

a.  The  Company  shall  prepare  and  file  with  the  SEC  such  amendments  (including  post-effective  amendments)  and  supplements  to  any
registration  statement  and  the  prospectus  used  in  connection  with  such  registration  statement,  which  prospectus  is  to  be  filed  pursuant  to  Rule  424
promulgated under the Securities Act, as may be necessary to keep the Registration Statement or any New Registration Statement effective at all times during
the Registration Period, and, during such period, comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities
of the Company covered by the Registration Statement or any New Registration Statement until such time as all of such Registrable Securities shall have been
disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in such registration statement.

b. The Company shall permit the Investor to review and comment upon the Registration Statement or any New Registration Statement and
all  amendments  and  supplements  thereto  at  least  two  (2)  Business  Days  prior  to  their  filing  with  the  SEC,  and  not  file  any  document  in  a  form  to  which
Investor reasonably objects. The Investor shall use its reasonable best efforts to comment upon the Registration Statement or any New Registration Statement
and any amendments or supplements thereto within two (2) Business Days from the date the Investor receives the final version thereof. The Company shall
furnish  to  the  Investor,  without  charge  any  correspondence  from  the  SEC  or  the  staff  of  the  SEC  to  the  Company  or  its  representatives  relating  to  the
Registration Statement or any New Registration Statement.

c. Upon request of the Investor, the Company shall furnish to the Investor, (i) promptly after the same is prepared and filed with the SEC, at
least one copy of such registration statement and any amendment(s) thereto, including financial statements and schedules, all documents incorporated therein
by reference and all exhibits, (ii) upon the effectiveness of any registration statement, a copy of the prospectus included in such registration statement and all
amendments  and  supplements  thereto  (or  such  other  number  of  copies  as  the  Investor  may  reasonably  request)  and  (iii)  such  other  documents,  including
copies of any preliminary or final prospectus, as the Investor may reasonably request from time to time in order to facilitate the disposition of the Registrable
Securities  owned  by  the  Investor.  For  the  avoidance  of  doubt,  any  filing  available  to  the  Investor  via  the  SEC’s  live  EDGAR  system  shall  be  deemed
“furnished to the Investor” hereunder.

3

 
 
 
 
 
 
 
 
 
 
d. The Company shall use reasonable best efforts to (i) register and qualify the Registrable Securities covered by a registration statement
under  such  other  securities  or  "blue  sky"  laws  of  such  jurisdictions  in  the  United  States  as  the  Investor  reasonably  requests,  (ii)  prepare  and  file  in  those
jurisdictions,  such  amendments  (including  post-effective  amendments)  and  supplements  to  such  registrations  and  qualifications  as  may  be  necessary  to
maintain  the  effectiveness  thereof  during  the  Registration  Period,  (iii)  take  such  other  actions  as  may  be  necessary  to  maintain  such  registrations  and
qualifications in effect at all times during the Registration Period, and (iv) take all other actions reasonably necessary or advisable to qualify the Registrable
Securities for sale in such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (x)
qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(d), (y) subject itself to general taxation in
any such jurisdiction, or (z) file a general consent to service of process in any such jurisdiction. The Company shall promptly notify the Investor who holds
Registrable  Securities  of  the  receipt  by  the  Company  of  any  notification  with  respect  to  the  suspension  of  the  registration  or  qualification  of  any  of  the
Registrable Securities for sale under the securities or "blue sky" laws of any jurisdiction in the United States or its receipt of actual notice of the initiation or
threatening of any proceeding for such purpose.

e. As promptly as practicable after becoming aware of such event or facts, the Company shall notify the Investor in writing of the happening
of any event or existence of such facts as a result of which the prospectus included in any registration statement, as then in effect, includes an untrue statement
of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, and promptly prepare a supplement or amendment to such registration statement to correct such untrue statement or
omission, and deliver a copy of such supplement or amendment to the Investor (or such other number of copies as the Investor may reasonably request). The
Company shall also promptly notify the Investor in writing (i) when a prospectus or any prospectus supplement or post-effective amendment has been filed,
and when a registration statement or any post-effective amendment has become effective (notification of such effectiveness shall be delivered to the Investor
by email or facsimile on the same day of such effectiveness and by overnight mail), (ii) of any request by the SEC for amendments or supplements to any
registration statement or related prospectus or related information, and (iii) of the Company's reasonable determination that a post-effective amendment to a
registration statement would be appropriate.

f. The Company shall use its reasonable best efforts to prevent the issuance of any stop order or other suspension of effectiveness of any
registration statement, or the suspension of the qualification of any Registrable Securities for sale in any jurisdiction and, if such an order or suspension is
issued, to obtain the withdrawal of such order or suspension at the earliest possible moment and to notify the Investor of the issuance of such order and the
resolution thereof or its receipt of actual notice of the initiation or threat of any proceeding for such purpose.

g. The Company shall (i) cause all the Registrable Securities to be listed on each securities exchange on which securities of the same class
or series issued by the Company are then listed, if any, if the listing of such Registrable Securities is then permitted under the rules of such exchange, or (ii)
secure designation and quotation of all the Registrable Securities on the Principal Market. The Company shall pay all fees and expenses in connection with
satisfying its obligation under this Section.

h. The Company shall cooperate with the Investor to facilitate the timely preparation and delivery of certificates (not bearing any restrictive
legend) representing the Registrable Securities to be offered pursuant to any registration statement and enable such certificates to be in such denominations or
amounts as the Investor may reasonably request and registered in such names as the Investor may request.

4

 
 
 
 
 
 
 
 
 
i. The Company shall at all times provide a transfer agent and registrar with respect to its Common Stock.

j.  If  reasonably  requested  by  the  Investor,  the  Company  shall  (i)  immediately  incorporate  in  a  prospectus  supplement  or  post-effective
amendment  such  information  as  the  Investor  believes  should  be  included  therein  relating  to  the  sale  and  distribution  of  Registrable  Securities,  including,
without limitation, information with respect to the number of Registrable Securities being sold, the purchase price being paid therefor and any other terms of
the offering of the Registrable Securities; (ii) make all required filings of such prospectus supplement or post-effective amendment as soon as practicable
upon notification of the matters to be incorporated in such prospectus supplement or post-effective amendment; and (iii) supplement or make amendments to
any registration statement.

k.  The  Company  shall  use  its  reasonable  best  efforts  to  cause  the  Registrable  Securities  covered  by  any  registration  statement  to  be
registered  with  or  approved  by  such  other  governmental  agencies  or  authorities  as  may  be  necessary  to  consummate  the  disposition  of  such  Registrable
Securities.

l. Within one (1) Business Day after any registration statement which includes the Registrable Securities is ordered effective by the SEC,
the Company shall deliver, and shall cause legal counsel for the Company to deliver, to the transfer agent for such Registrable Securities (with copies to the
Investor)  confirmation  that  such  registration  statement  has  been  declared  effective  by  the  SEC  in  the  form  attached  hereto  as  Exhibit  A.  Thereafter,  if
requested by the Buyer at any time, the Company shall require its counsel to deliver to the Buyer a written confirmation whether or not the effectiveness of
such  registration  statement  has  lapsed  at  any  time  for  any  reason  (including,  without  limitation,  the  issuance  of  a  stop  order)  and  whether  or  not  the
registration statement is current and available to the Buyer for sale of all of the Registrable Securities.

m.  The  Company  shall  take  all  other  reasonable  actions  necessary  to  expedite  and  facilitate  disposition  by  the  Investor  of  Registrable

Securities pursuant to any registration statement.

4. OBLIGATIONS OF THE INVESTOR.

a. The Company shall notify the Investor in writing of the information the Company reasonably requires from the Investor in connection
with  any  registration  statement  hereunder.  Within  two  (2)  Business  Days  of  the  Company’s  request,  the  Investor  shall  furnish  to  the  Company  such
information regarding itself, the Registrable Securities held by it and the intended method of disposition of the Registrable Securities held by it as shall be
reasonably  required  to  effect  the  registration  of  such  Registrable  Securities  and  shall  execute  such  documents  in  connection  with  such  registration  as  the
Company may reasonably request.

b.  The  Investor  agrees  to  cooperate  with  the  Company  as  reasonably  requested  by  the  Company  in  connection  with  the  preparation  and

filing of any registration statement hereunder.

5

 
 
 
 
 
 
 
 
 
 
 
c. The Investor agrees that, upon receipt of any notice from the Company of the happening of any event or existence of facts of the kind
described in Section 3(f) or the first sentence of Section 3(e), the Investor will immediately discontinue disposition of Registrable Securities pursuant to any
registration  statement(s)  covering  such  Registrable  Securities  until  the  Investor's  receipt  of  the  copies  of  the  supplemented  or  amended  prospectus
contemplated by Section 3(f) or the first sentence of Section 3(e). Notwithstanding anything to the contrary, the Company shall cause its transfer agent to
promptly deliver shares of Common Stock without any restrictive legend in accordance with the terms of the Purchase Agreement in connection with any sale
of Registrable Securities with respect to which an Investor has entered into a contract for sale prior to the Investor's receipt of a notice from the Company of
the happening of any event of the kind described in Section 3(f) or the first sentence of Section 3(e) and for which the Investor has not yet settled.

5. EXPENSES OF REGISTRATION.

All  reasonable  expenses,  other  than  sales  or  brokerage  commissions,  incurred  in  connection  with  registrations,  filings  or  qualifications
pursuant  to  Sections  2  and  3,  including,  without  limitation,  all  registration,  listing  and  qualifications  fees,  printers  and  accounting  fees,  and  fees  and
disbursements of counsel for the Company, shall be paid by the Company.

6. INDEMNIFICATION.

a.  To  the  fullest  extent  permitted  by  law,  the  Company  will,  and  hereby  does,  indemnify,  hold  harmless  and  defend  the  Investor,  each
Person, if any, who controls the Investor, the members, the directors, officers, partners, employees, agents, representatives of the Investor and each Person, if
any, who controls the Investor within the meaning of the Securities Act or the Securities Exchange Act of 1934, as amended (the "Exchange Act") (each, an
"Indemnified Person"), against any losses, claims, damages, liabilities, judgments, fines, penalties, charges, costs, attorneys' fees, amounts paid in settlement
or  expenses,  joint  or  several,  (collectively,  "Claims")  incurred  in  investigating,  preparing  or  defending  any  action,  claim,  suit,  inquiry,  proceeding,
investigation or appeal taken from the foregoing by or before any court or governmental, administrative or other regulatory agency, body or the SEC, whether
pending or threatened, whether or not an indemnified party is or may be a party thereto ("Indemnified Damages"), to which any of them may become subject
insofar  as  such  Claims  (or  actions  or  proceedings,  whether  commenced  or  threatened,  in  respect  thereof)  arise  out  of  or  are  based  upon:  (i)  any  untrue
statement  or  alleged  untrue  statement  of  a  material  fact  in  the  Registration  Statement,  any  New  Registration  Statement  or  any  post-effective  amendment
thereto or in any filing made in connection with the qualification of the offering under the securities or other "blue sky" laws of any jurisdiction in which
Registrable Securities are offered ("Blue Sky Filing"), or the omission or alleged omission to state a material fact required to be stated therein or necessary to
make  the  statements  therein  not  misleading,  (ii)  any  untrue  statement  or  alleged  untrue  statement  of  a  material  fact  contained  in  the  final  prospectus  (as
amended or supplemented, if the Company files any amendment thereof or supplement thereto with the SEC) or the omission or alleged omission to state
therein any material fact necessary to make the statements made therein, in light of the circumstances under which the statements therein were made, not
misleading, (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any other law, including, without limitation, any
state securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities pursuant to the Registration Statement or any
New Registration Statement or (iv) any material violation by the Company of this Agreement (the matters in the foregoing clauses (i) through (iv) being,
collectively, "Violations"). The Company shall reimburse each Indemnified Person promptly as such expenses are incurred and are due and payable, for any
reasonable legal fees or other reasonable expenses incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything
to the contrary contained herein, the indemnification agreement contained in this Section 6(a): (i) shall not apply to a Claim by an Indemnified Person arising
out of or based upon a Violation which occurs in reliance upon and in conformity with information about the Investor furnished in writing to the Company by
such  Indemnified  Person  expressly  for  use  in  connection  with  the  preparation  of  the  Registration  Statement,  any  New  Registration  Statement  or  any  such
amendment thereof or supplement thereto, if such prospectus was timely made available by the Company pursuant to Section 3(c) or Section 3(e); (ii) with
respect  to  any  superseded  prospectus,  shall  not  inure  to  the  benefit  of  any  such  person  from  whom  the  person  asserting  any  such  Claim  purchased  the
Registrable Securities that are the subject thereof (or to the benefit of any person controlling such person) if the untrue statement or omission of material fact
contained  in  the  superseded  prospectus  was  corrected  in  the  revised  prospectus,  as  then  amended  or  supplemented,  if  such  revised  prospectus  was  timely
made available by the Company pursuant to Section 3(c) or Section 3(e), and the Indemnified Person was promptly advised in writing not to use the incorrect
prospectus  prior  to  the  use  giving  rise  to  a  violation  and  such  Indemnified  Person,  notwithstanding  such  advice,  used  it;  (iii)  shall  not  be  available  to  the
extent such Claim is based on a failure of the Investor to deliver or to cause to be delivered the prospectus made available by the Company, if such prospectus
was timely made available by the Company pursuant to Section 3(c) or Section 3(e); and (iv) shall not apply to amounts paid in settlement of any Claim if
such settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld. Such indemnity shall remain
in  full  force  and  effect  regardless  of  any  investigation  made  by  or  on  behalf  of  the  Indemnified  Person  and  shall  survive  the  transfer  of  the  Registrable
Securities by the Investor pursuant to Section 9.

6

 
 
 
 
 
 
 
 
 
b. In connection with the Registration Statement or any New Registration Statement, the Investor agrees to indemnify, hold harmless and
defend,  to  the  same  extent  and  in  the  same  manner  as  is  set  forth  in  Section  6(a),  the  Company,  each  of  its  directors,  each  of  its  officers  who  signs  the
Registration Statement or any New Registration Statement, each Person, if any, who controls the Company within the meaning of the Securities Act or the
Exchange Act (collectively and together with an Indemnified Person, an "Indemnified Party"), against any Claim or Indemnified Damages to which any of
them may become subject, under the Securities Act, the Exchange Act or otherwise, insofar as such Claim or Indemnified Damages arise out of or are based
upon any Violation, in each case to the extent, and only to the extent, that such Violation occurs in reliance upon and in conformity with written information
about the Investor set forth on Exhibit B attached hereto and furnished to the Company by the Investor expressly for use in connection with such registration
statement; and, subject to Section 6(d), the Investor will reimburse any legal or other expenses reasonably incurred by them in connection with investigating
or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 6(b) and the agreement with respect to contribution
contained  in  Section  7  shall  not  apply  to  amounts  paid  in  settlement  of  any  Claim  if  such  settlement  is  effected  without  the  prior  written  consent  of  the
Investor, which consent shall not be unreasonably withheld; provided, further, however, that the Investor shall be liable under this Section 6(b) for only that
amount of a Claim or Indemnified Damages as does not exceed the net proceeds to the Investor as a result of the sale of Registrable Securities pursuant to
such registration statement. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified
Party and shall survive the transfer of the Registrable Securities by the Investor pursuant to Section 9.

c. Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any action
or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party shall, if a Claim in respect
thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying party a written notice of the commencement thereof,
and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the
Indemnified Party, as the case may be; provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its own counsel with
the  reasonable  fees  and  expenses  to  be  paid  by  the  indemnifying  party,  if,  in  the  reasonable  opinion  of  counsel  retained  by  the  indemnifying  party,  the
representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential
differing  interests  between  such  Indemnified  Person  or  Indemnified  Party  and  any  other  party  represented  by  such  counsel  in  such  proceeding.  It  is
understood  and  agreed,  however,  that  the  Indemnifying  Party  shall  only  be  responsible  to  pay  the  reasonable  fees  and  expenses  of  one  law  firm  for  all
Indemnified Parties. The Indemnified Party or Indemnified Person shall cooperate fully with the indemnifying party in connection with any negotiation or
defense  of  any  such  action  or  claim  by  the  indemnifying  party  and  shall  furnish  to  the  indemnifying  party  all  information  reasonably  available  to  the
Indemnified  Party  or  Indemnified  Person  which  relates  to  such  action  or  claim.  The  indemnifying  party  shall  keep  the  Indemnified  Party  or  Indemnified
Person fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable for
any settlement of any action, claim or proceeding effected without its written consent, provided, however, that the indemnifying party shall not unreasonably
withhold, delay or condition its consent. No indemnifying party shall, without the consent of the Indemnified Party or Indemnified Person, consent to entry of
any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party or Indemnified Person of a release from all liability in respect to such claim or litigation. Following indemnification as provided for
hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified Person with respect to all third parties, firms or
corporations  relating  to  the  matter  for  which  indemnification  has  been  made.  The  failure  to  deliver  written  notice  to  the  indemnifying  party  within  a
reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified
Party under this Section 6, except to the extent that the indemnifying party is prejudiced in its ability to defend such action.

7

 
 
 
 
 
 
d.  The  indemnification  required  by  this  Section  6  shall  be  made  by  periodic  payments  of  the  amount  thereof  during  the  course  of  the

investigation or defense, as and when bills are received or Indemnified Damages are incurred.

e. The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party or

Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject to pursuant to the law.

7. CONTRIBUTION.

To  the  extent  any  indemnification  by  an  indemnifying  party  is  prohibited  or  limited  by  law,  the  indemnifying  party  agrees  to  make  the
maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6 to the fullest extent permitted by law; provided,
however, that: (i) no seller of Registrable Securities guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be
entitled to contribution from any seller of Registrable Securities who was not guilty of fraudulent misrepresentation; and (ii) contribution by any seller of
Registrable Securities shall be limited in amount to the net amount of proceeds received by such seller from the sale of such Registrable Securities.

8. REPORTS AND DISCLOSURE UNDER THE SECURITIES ACTS.

With a view to making available to the Investor the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or
regulation of the SEC that may at any time permit the Investor to sell securities of the Company to the public without registration ("Rule 144"), the Company
agrees, at the Company’s sole expense, to:

a. make and keep public information available, as those terms are understood and defined in Rule 144;

8

 
 
 
 
 
 
 
 
 
 
 
b. file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange
Act so long as the Company remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions
of Rule 144;

c. furnish to the Investor so long as the Investor owns Registrable Securities, promptly upon request, (i) a written statement by the Company
that it has complied with the reporting and or disclosure provisions of Rule 144, the Securities Act and the Exchange Act, (ii) a copy of the most recent annual
or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably
requested to permit the Investor to sell such securities pursuant to Rule 144 without registration; and

d. take such additional action as is requested by the Investor to enable the Investor to sell the Registrable Securities pursuant to Rule 144,
including, without limitation, delivering all such legal opinions, consents, certificates, resolutions and instructions to the Company’s Transfer Agent as may
be requested from time to time by the Investor and otherwise fully cooperate with Investor and Investor’s broker to effect such sale of securities pursuant to
Rule 144.

The  Company  agrees  that  damages  may  be  an  inadequate  remedy  for  any  breach  of  the  terms  and  provisions  of  this  Section  8  and  that
Investor shall, whether or not it is pursuing any remedies at law, be entitled to equitable relief in the form of a preliminary or permanent injunctions, without
having to post any bond or other security, upon any breach or threatened breach of any such terms or provisions.

9. ASSIGNMENT OF REGISTRATION RIGHTS.

The Company shall not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Investor. The
Investor may not assign its rights under this Agreement without the written consent of the Company, other than to an affiliate of the Investor controlled by
Jonathan Cope or Josh Scheinfeld.

10. AMENDMENT OF REGISTRATION RIGHTS.

No provision of this Agreement may be amended or waived by the parties from and after the date that is one Business Day immediately
preceding the filing of the initial Registration Statement with the SEC. Subject to the immediately preceding sentence, no provision of this Agreement may be
(i)  amended  other  than  by  a  written  instrument  signed  by  both  parties  hereto  or  (ii)  waived  other  than  in  a  written  instrument  signed  by  the  party  against
whom enforcement of such waiver is sought. Failure of any party to exercise any right or remedy under this Agreement or otherwise, or delay by a party in
exercising such right or remedy, shall not operate as a waiver thereof.

11. MISCELLANEOUS.

a. A Person is deemed to be a holder of Registrable Securities whenever such Person owns or is deemed to own of record such Registrable
Securities. If the Company receives conflicting instructions, notices or elections from two or more Persons with respect to the same Registrable Securities, the
Company shall act upon the basis of instructions, notice or election received from the registered owner of such Registrable Securities.

Purchase Agreement, dated as of March 22, 2016 (the “Purchase Agreement”), entered into by and between the Company and Lincoln Park Capital Fund,
LLC (the “Buyer”) pursuant to which the Company has agreed to issue to the Buyer shares of the Company's Common Stock, par value $0.001 per share (the
“Common  Stock”),  in  an  amount  up  to  Twelve  Million  Dollars  ($12,000,000)  (the  “Purchase  Shares”),  in  accordance  with  the  terms  of  the  Purchase
Agreement. In connection with the transactions contemplated by the Purchase Agreement, the Company has registered with the U.S. Securities & Exchange

Pursuant to the Purchase Agreement, the Company also has entered into a Registration Rights Agreement, dated as of March 22, 2016 with the Buyer (the

under the Securities Act of 1933, as amended (the “Securities Act”). In connection with the Company's obligations under the Purchase Agreement and the
Registration  Rights  Agreement,  on  [_____________],  2016,  the  Company  filed  a  Registration  Statement  (File  No.  333-[_________])  (the  “Registration
Statement”) with the Securities and Exchange Commission (the “SEC”) relating to the resale of the Purchase Shares and the Commitment Shares.

In connection with the foregoing, we advise you that a member of the SEC's staff has advised us by telephone that the SEC has entered an order
declaring the Registration Statement effective under the Securities Act at [_____] [A.M./P.M.] on [__________], 201[__] and we have no knowledge, after
telephonic inquiry of a member of the SEC's staff, that any stop order suspending its effectiveness has been issued or that any proceedings for that purpose are
pending before, or threatened by, the SEC and the Purchase Shares and the Commitment Shares are available for resale under the Securities Act pursuant to
the Registration Statement and may be issued without any restrictive legend.
