BioTherapeutics Overview

SGX94

In  December  2012,  we  acquired  a  drug  technology,  we  refer  to  as  SGX94,  representing  what  we  believe  is  a  novel  approach  to  modulation  of  the  innate
immune system. SGX94 is an IDR that regulates the innate immune system to simultaneously reduce inflammation, eliminate infection and enhance tissue
healing. As part of the acquisition, we acquired all rights, including composition of matter patents, preclinical and Phase 1 clinical study datasets for SGX94.
We also assumed a license agreement with the University of British Columbia (“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.

SGX94 is the research name for the active ingredient in SGX942, which is the research name for the finished drug product being studied in oral mucositis. It
is  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  provide  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 are 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.

We have a strong worldwide IP position on SGX94 and related analogs including composition of matter. SGX94 was developed pursuant to discoveries made
by Professors B. Brett Finlay and Robert Hancock of the UBC and approximately $40 million has been invested towards its development to date, inclusive of
government grants.

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 showed a strong safety profile 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 United States Food and Drug Administration
(the  “FDA”).  Market  opportunities  include,  but  are  not  limited  to,  mucositis,  acute  bacterial  skin  and  skin  structure  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

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. Oral mucositis
in  this  patient  population  is  an  area  of  unmet  medical  need  where  there  are  currently  no  approved  drug  therapies.  Accordingly,  we  received  “Fast  Track”
designation for the treatment of oral mucositis as a result of radiation and/or chemotherapy treatment in head and neck cancer patients from the FDA in the
first  half  of  2013.  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 New Drug Application (“NDA”) for SGX942 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, which implies an abbreviated review time of six months.

We believe the potential worldwide market for SGX942 is in excess of $500 million for all applications, including oral mucositis.

About 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 gastro-intestinal 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  now  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 (>80% incidence of severe mucositis) and is common (40-100% incidence) 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 gastrointestinal inflammation. BDP
has been marketed in the U.S. and worldwide since the early 1970s as the active pharmaceutical ingredient in a nasal spray and in a metered-dose inhaler for
the treatment of patients with allergic rhinitis and asthma. Oral BDP is specifically formulated for oral administration as a single product consisting of two
tablets. One tablet is intended to release BDP in the upper sections of the GI tract and the other tablet is intended to release BDP in the lower sections of the
GI tract.

Based  on  its  pharmacological  characteristics,  oral  BDP may  have  utility  in  treating  other  conditions  of  the  gastrointestinal  tract  having  an  inflammatory
component. We have an issued U.S. patent 8,263,582 claiming the use of oral BDP as a method of treating inflammatory disorders of the gastrointestinal
tract, including Crohn’s disease, and an issued U.S. patent 6,096,731 claiming the use of oral BDP as a method for preventing and treating the tissue damage
that  is  associated  with  both  GI  GVHD  following  hematopoietic  cell  transplantation,  as  well  as  GVHD  which  also  occurs  following  organ  allograft
transplantation. 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. We are planning to pursue development programs in the treatment of pediatric
Crohn’s disease, acute radiation enteritis, chronic GI GVHD 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  believe  the  potential  worldwide  market  for  oral  BDP  is  in  excess  of  $500  million  for  all  GI  applications,  namely,  pediatric  Crohn’s  disease,  radiation
enteritis, GI ARS, and chronic GI GVHD.

In  addition  to  issued  patents  and  pending  worldwide  patent  applications  held  by  or  exclusively  licensed  to  us,  oral  BDP  would  benefit  from  orphan  drug
designations in the U.S. and in Europe. Orphan drug designations provide for 7 and 10 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 awarded SGX203 orphan drug designation as well as Fast Track designation for the treatment of
pediatric Crohn's disease.

About Pediatric Crohn's Disease

Crohn's disease is an ongoing disorder that 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 (~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. 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 to determine potential next steps forward with the clinical
development program.

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

About 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.

7

 
 
 
 
 
 
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 2-6 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.

orBec® –for Treating Chronic GI GVHD

orBec® is a two tablet delivery system of BDP specifically designed for oral use that allows for delivery of immediate and delayed release BDP to treat the
gastrointestinal manifestation of chronic GVHD, the organ system where GVHD is most frequently encountered and highly problematic. orBec® is intended
to reduce the need for systemic immunosuppressive drugs such as prednisone to treat chronic GI GVHD. The active ingredient in orBec® is BDP, a highly
potent, topically active corticosteroid that has a local effect on inflamed tissue. 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. orBec® has been
awarded orphan drug designations in the U.S. and in Europe for the treatment of GI GVHD. In September 2012, we received a $300,000 two-year SBIR grant
awarded by the NIH to support a Phase 2 study for the treatment of chronic GI GVHD.

About Chronic GVHD

GVHD is a major complication of allogeneic hematopoietic cell transplantation. GVHD is an inflammatory disease initiated by T cells in the donor graft that
recognize histocompatibility and other tissue antigens of the host, and is mediated by a variety of effector cells and inflammatory cytokines. GVHD presents
in both acute and chronic forms. The symptoms of chronic GVHD typically present at between 100 days and three years post-transplant.

Chronic  GVHD  has  features  resembling  autoimmune  and  other  immunologic  disorders  such  as  scleroderma,  Sjögren  syndrome,  primary  biliary  cirrhosis,
wasting syndrome, bronchiolitis obliterans, immune cytopenias and chronic immunodeciency. The manifestations of chronic GVHD may be restricted to a
single  organ  or  tissue  or  may  be  widespread.  Chronic  GVHD  can  lead  to  debilitating  consequences,  e.g.,  joint  contractures,  loss  of  sight,  end-stage  lung
disease, or mortality resulting from profound chronic immune suppression leading to recurrent or life-threatening infections.

Treatment of chronic GVHD is a challenge because it can be refractory to frontline immunosuppression. High-dose systemic corticosteroids are used with
some  success  but  carry  significant  toxicity.  The  risks  of  prolonged  immunosuppression  include  local  and  disseminated  infections,  Epstein-Barr  virus
associated  lymphoproliferative  disease,  hypothalamic-pituitary-adrenal  (“HPA”)  axis  suppression,  myopathy,  glucose  intolerance,  neuropsychiatric  disease
and bone demineralization.

8

 
 
 
 
We estimate, based upon our review of historic published studies and reports, and an interpolation of data on the incidence of chronic GVHD, there to be
6,000 patients annually in the U.S., with a comparable number in Europe that suffer from chronic GVHD.

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, 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.  The  savings  realized  from  the  elimination  of  cold  chain  costs  and  related  product  losses  would  in  turn  significantly  increase  the  profitability  of
vaccine products. Elimination of the cold chain would also 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 is being supported pursuant to our $9.4 million National Institute of Allergy and Infectious Diseases (“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™,
made  under  precise  lyophilization  conditions  using  excipients  that  aid  in  maintaining  native  protein  structure  of  the  ricin  A  chain,  the  immunogenic
compound  of  the  vaccine.  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. Confirmatory results have extended the stability to one year when the
vaccine is kept at 40 degrees C. 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.

Near term progress with ThermoVax™ will allow us to seek out potential partnerships with companies marketing FDA/ex-U.S. health authority approved
Alum adjuvanted vaccines that are interested in eliminating the need for cold chain for their products. ThermoVax™ will further enable Soligenix to expand
its 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).

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.” These patents and their corresponding foreign filings are pending and licensed to Soligenix 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.

RiVax™ – Ricin Toxin Vaccine

RiVax™ is our proprietary vaccine developed to protect against exposure to ricin toxin, and is the first ricin vaccine. With RiVax™, we are a world leader in
ricin toxin vaccine research. 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.  Two  Phase  1  human  clinical  trials  have  been  completed.  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  the  University  of  Texas  Southwestern  Medical  Center
(“UTSW”) where the vaccine originated. The second clinical trial was supported by a grant from the FDA's Office of Orphan Products to UTSW. Soligenix
and  UTSW  have  collectively  received  approximately  $25  million  in  grant  funding  from  the  NIH  for  RiVax™.  Results  of  the  first  Phase  1  human  trial  of
RiVax™ established that the immunogen was safe and induced antibodies anticipated to 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,  sponsored  by  UTSW,
evaluated a more potent formulation of RiVax™ that contained an aluminum adjuvant (Alum), was completed in September 2012. 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.

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. RiVax™ has also 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.

About 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 Centers 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.

10

 
 
 
 
In January of 2012, a Request for Information (“RFI”) was issued by the Chemical Biological Medical Systems – Joint Vaccine Acquisition Program of the
Department of Defense (“DoD”). This RFI was titled “Development of a Ricin Toxin Vaccine to FDA Approval”, and marks the first time any agency of the
U.S.  government  has  specifically  indicated  an  interest  in  development  of  a  vaccine  against  ricin  toxin.  We  intend  to  pursue  this  avenue  of  funding  to  the
fullest extent.

VeloThrax™ – Anthrax Vaccine

VeloThrax™  is  our  newly  acquired  proprietary  vaccine  based  on  a  recombinant  Protective  Antigen  (“rPA”)  derivative  intended  for  use  against  anthrax.
Soligenix has entered into an exclusive license option with Harvard College to license VeloThrax™ (also known as DNI for dominant negative inhibitor) for a
vaccine directed at the prevention of anthrax infection of humans. VeloThrax™ is a translocation-deficient mutant of PA with double mutations of K397D and
D425K  that  impede  the  conformational  changes  necessary  for  endosomal  membrane  translocation  into  the  cell  cytoplasm.  In  the  absence  of  that  PA
translocation step, anthrax toxin trafficking and function cease. VeloThrax™ is also considered a more immunogenic candidate than native rPA. This apparent
increase  in  immunogenicity  suggests  that  the  DNI  rPA  is  processed  and  presented  to  the  immune  system  more  efficiently  by  cellular  antigen  processing
pathways, which is consistent with known properties of the molecule.

DNI  versions  of  rPA  such  as  VeloThrax™  are  also  capable  of  inducing  antibodies  that  neutralize  the  activity  of  the  anthrax  toxin  complex.  Unlike  fully-
functional  rPA,  VeloThrax™  might  be  given  to  a  patient  post-exposure  without  risk  of  enhancing  intoxication  during  an  infection,  although  clinical  tests
involving  intravenous  administration  of  potentially  therapeutic  levels  of  DNI  rPA  resulted  in  serious  adverse  events  and  so  further  development  of  this
product as a therapeutic biological for blocking the effects of infection by B. anthracis was discontinued. Soligenix intends to test VeloThrax™ at a 1,000 fold
lower dose than previously tested for an intramuscular or intradermal vaccine.

VeloThrax™’s  greater  immunogenicity  could  lead  to  a  vaccine  that  can  be  administered  in  the  fewest  possible  doses  to  induce  the  highest  level  of  toxin
neutralizing antibodies. Utilizing ThermoVax™, we believe that we will be able to develop VeloThrax™ into a vaccine with an improved stability profile, an
issue  that  has  proven  challenging  in  the  development  of  other  anthrax  vaccines.  Extended  stability  at  ambient  temperatures  would  be  a  significant
improvement for stockpiled vaccines and one which is not expected from conventional vaccines. Further, a large-scale, current Good Manufacturing Practice
(“cGMP”)  production  methodology  has  already  been  completed.  Assuming  long-term  stability  can  be  met,  VeloThrax™  could  be  stockpiled  for  general
prophylactic as well as a post exposure use.

The overall objective of the VeloThrax™ program is to rapidly and efficiently develop a next generation anthrax vaccine which combines a well-established,
safe  and  relatively  low  risk  vaccine  development  and  dosing  approach  with  targeted,  proven  innovative  strategies.  VeloThrax™  will  potentially  be  a
combination  of  a  stable,  readily  manufactured  mutant  rPA  subunit  antigen  with  next  generation,  clinically  compatible  adjuvants  which  have  been
demonstrated to enhance potency and reduce the time and number of vaccine doses required to achieve protective titer using a variety of vaccine antigens.
This blend of proven yet innovative technologies will provide the Public Health Emergency Medical Countermeasures Enterprise (“PHEMCE”) and the DoD
with a safe and stable alternative to the existing licensed anthrax vaccine product. Soligenix also proposes to adapt newly developed glassification technology
(initially  developed  under  an  ongoing  NIAID  grant  to  stabilize  exceptionally  unstable  ricin  toxin/adjuvant  formulations)  to  enable  a  thermostable,  dried,
single vial, pre-formulated adjuvanted rPA vaccine which is suitable for both long term storage and field use without typical cold chain constraints.

Assuming development efforts are successful for VeloThrax™, we believe potential government procurement contract(s) could reach $500 million.

About Anthrax

Anthrax is an acute infectious disease that is easily transmitted to humans by environmentally durable spores that are produced by Bacillus anthracis. Because
the  spores  are  robust  and  contagious,  anthrax  is  considered  a  Category  A  bioterror  threat.  Anthrax  infection  can  occur  in  three  forms:  cutaneous  (skin),
inhalation, and gastrointestinal. Inhaled spores can cause a rapidly progressing form of anthrax since the spores are transported to lymph nodes near the lungs
where  they  germinate,  releasing  vegetative  bacteria  into  the  bloodstream.  Bacteria  synthesize  a  complex  series  of  toxin  components  that  make  up  anthrax
toxin, resulting in overwhelming toxemia that causes shock and organ failure. Treatment of anthrax involves long-term antibiotic therapy, since ungerminated
spores can lie dormant in the lungs for up to 60 days. Only a few inhaled spores can cause inhalational anthrax. Once the toxin has entered the bloodstream,
antibiotics are ineffective, and only toxin-specific therapy is effective. Passively transferred antibodies can neutralize anthrax toxins and can be used post-
exposure in conjunction with antibiotics. Because of the long residence time of spores in the lung, it is possible to vaccinate post-exposure, but the onset of
neutralizing antibodies must occur during the period of antibiotic therapy.

OrbeShield™ –for Treating GI ARS

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

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

The GI tract is highly sensitive to ionizing radiation and the destruction of epithelial tissue is one of the first effects of radiation exposure. The rapid loss of
epithelial cells leads to inflammation and infection that are often the primary cause of death in acute radiation injury. This concept of GI damage also applies
to the clinical setting of oncology, where high doses of radiation cannot be administered effectively to the abdomen because radiation is very toxic to the
intestines.  This  is  the  same  type  of  toxicity  that  occurs  in  Soligenix’s  acute  radiation  enteritis  clinical  program  with  SGX201.  As  a  result,  there  is  a  dual
avenue  of  development  for  Soligenix,  and  OrbeShield™  is  potentially  a  “dual  use”  compound,  a  desirable  characteristic  which  is  a  specific  priority  of
BARDA for ARS and other medical countermeasure indications. 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 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 for a total of three years and up to $6.4 million.

The FDA has cleared the IND application for OrbeShield™ for the mitigation of morbidity and mortality associated with GI ARS. 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 awarded 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  contract(s)  could  reach  as  much  as  $450
million.

About GI ARS

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  >2  Gy  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 in 5-15 days. The GI tract is highly sensitive due to
the requirement for incessant proliferation of 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. Therefore, there
is an urgent need to develop specific medical counter measures against the lethal pathophysiological manifestations of radiation-induced GI injury.

SGX943/SGX101– for Treating Melioidosis

SGX943 is the research name for the finished drug product, containing the active ingredient SGX94, which is being studied in melioidosis. A preliminary
study with SGX943 has demonstrated efficacy. Further preclinical studies are planned with the pursuit of grant funding. Because SGX943 directly targets the
innate immune system (and does not attempt to kill the bacteria directly), 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.
Thus, SGX943 may represent a much-needed novel and additive therapy for melioidosis.  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.

SGX101 is the research name for the human monoclonal antibody therapy for the treatment of melioidosis based upon Intrexon’s advanced human antibody
discovery, isolation, and production technologies. As this research and development program progresses, grant funding will be pursued.

About 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. Therefore, there is a significant 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. Moreover, the organism has a
worldwide distribution and the full extent of global spread is likely underestimated. In Northeast Thailand, which has the highest incidence of melioidosis
recorded in the world, 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. Melioidosis has been under recognized and is likely to be under-reported in China.

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

Before  marketing,  each  of  our  products  must  undergo  an  extensive  regulatory  approval  process  conducted  by  the  FDA  and  applicable  agencies  in  other
countries. Testing, manufacturing, commercialization, advertising, promotion, export and marketing, among other things, of the proposed products are subject
to extensive regulation by government authorities in the U.S. and other countries. All products must go through a series of tests, including advanced human
clinical trials, which the FDA is allowed to suspend as it deems necessary to protect the safety of patients.

Our products will require regulatory clearance by the FDA and by comparable agencies in other countries, prior to commercialization. The nature and extent
of regulation differs with respect to different products. In order to test, produce and market certain therapeutic products in the U.S., mandatory procedures and
safety standards, approval processes, manufacturing and marketing practices established by the FDA must be satisfied.

13

 
 
 
 
An IND application is required before human clinical testing in the U.S. of a new drug compound or biological product can commence. 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.

With certain exceptions, once successful clinical testing is completed, the sponsor can submit an NDA for approval of a drug. 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, 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.  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
products. 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 Federal Food, Drug, and Cosmetic Act, 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 Federal Food, Drug, and Cosmetic Act involving medical devices.

14

 
 
 
 
 
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 Biologices Licensing Application (“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 much less 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 much greater.  Indeed, almost three years after the enactment of the Patient Protection and Affordable Care Act, no biosimilar
application has even been filed with the FDA.

Marketing Strategies

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; 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.

We intend to seek partners to out-license all or portions of our programs. We are keen to advance our products through development and into the market in as
many indications as possible.

We  have  had  and  are  having  strategic  discussions  with  a  number  of  pharmaceutical  companies  regarding  the  partnering  or  sale  of  our  biodefense  vaccine
products. We may market our biodefense vaccine products directly to government agencies. 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.

Competition

Our  competitors  are  pharmaceutical  and  biotechnology  companies,  most  of  whom  have  considerably  greater  financial,  technical,  and  marketing  resources
than we currently have. Another source of competing technologies is universities and other research institutions, including the U.S. Army Medical Research
Institute of Infectious Diseases, and we face competition from other companies to acquire rights to those technologies.

SGX94/942 Competition

SGX94 has a novel mechanism of action in combating bacterial infections and is complementary to the use of antibiotics. Thus 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 (e.g. Celtaxsys, Innaxon Therapeutics, Innate Pharma).

There is currently one drug approved for the treatment of oral mucositis in hematological cancer only (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 at least 5 drugs in clinical development for oral mucositis – 1
in phase 3 (under development by Daewoong Pharmaceutical Co., Ltd), 3 in Phase 2 (under development by ActoGenix N.V., BioAlliance Pharma S.A. and
Alder Biopharmaceuticals Inc.) and 1 in Phase 1 (under development by PolyMedix, Inc.). 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; however,
none of these devices are biologically based.

Oral BDP Competition

There  are  currently  approximately  41  compounds  either  on  the  market  or  in  clinical  development  for  Crohn’s  disease  of  which  14  are  biologics,  six
immunomodulators, three cell-based therapies, two steroids, two anti-inflammatory, two are 5-ASAs, one is antibiotic, and 11 others that are unclassified. In
the U.S., there are 24 compounds on market or in development including four compounds in Phase 3.

There are four compounds currently in development or on the market specifically for pediatric Crohn’s disease. Of these, Remicade (infliximab) is the only
compound  currently  with  an  indication  in  pediatric  Crohn’s  disease.  There  are  two  other  marketed  biologics,  Cimzia  (certolizumab)  and  Tysabri
(natalizumab),  in  Phase  2  for  pediatric  Crohn’s.  Entocort  (enteric-coated  budesonide)  is  also  currently  in  Phase  3  trials  in  pediatric  Crohn’s  disease.  We
believe that SGX203’s unique release characteristics, intended to deliver topically active therapy to both the upper and lower gastrointestinal systems, should
make SGX203 an attractive alternative to existing therapies for inflammatory diseases of the gastrointestinal tract.

Competition is also intense in the gastroenterology and transplant areas. Companies are attempting to develop technologies to treat GVHD by suppressing the
immune system through various mechanisms. Some companies, including Osiris, Abgenix, and PDL BioPharma, Inc., are developing monoclonal antibodies
to treat GVHD. Novartis, Medimmune, and Ariad are developing both gene therapy products and small molecules to treat GVHD. All of these products are in
various stages of development. Kiadis Pharma is also developing products for the treatment of GVHD. In addition, there are investigator-sponsored clinical
trials exploring the use of approved drugs such as Enbrel®, which has been approved by the FDA for the treatment of rheumatoid arthritis, in the treatment of
GVHD.

Additionally, Chiesi Pharmaceuticals markets, in certain countries in Europe, a delayed-release oral formulation of beclomethasone dipropionate, the active
ingredient of orBec®, called CLIPPER™ for ulcerative colitis.

ThermoVaxTM Competition

Multiple  groups  and  companies  are  working  to  address  the  unmet  need  of  vaccine  thermostability  using  a  variety  of  technologies.  In  addition,  both  non-
governmental  organizations  such  as  the  Bill  and  Melinda  Gates  Foundation  and  PATH,  as  well  as  academic  organizations  such  as  the  Kansas  University
Macromolecular and Vaccine Stabilization Center have programs designed to advance technologies which may address this need.

The majority of 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 and synthetic polymers such as Pluronic F127 (Endo
Pharmaceuticals under Gates Foundation funding). VBI (Variation Biotechnologies, Inc.) intends to employ a lipid system (resembling liposomes) to stabilize
viral antigens, including virus-like particles (VLPs), and apply it to a conventional influenza vaccine among others

16

 
 
 
Other approaches involve process variations to freeze-dry live virus vaccines. For example, PaxVax intends 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 has the capacity 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), 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.  Another    competitor,  Endo  Pharmaceuticals  is  working  to  identify  Pluronic  polymer-based  formulations  that  stabilize  measles  and  hepatitis  B
vaccines from -10°C to 45°C.

Additionally, companies like Pharmathene, Panacea Biotech, and Compass Biotech 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 the our technologies.

The currently available anthrax vaccine known as BioThrax® (Anthrax Vaccine Adsorbed or AVA) marketed by Emergent BioSolutions, Inc. was developed
nearly 50 years ago from a culture filtrate derived from anthrax bacteria. Consequently, it contains a number of different proteins, some of which are believed
to potentially contribute to the adverse events that have been reported in the literature (up to 7-8% serious adverse events) and which prompted agencies like
the Institute of Medicine to recommend adoption of newer and safer anthrax vaccines. BioThrax® is FDA approved for the prevention of anthrax infection,
but requires five doses over a period of eighteen months to achieve protective immunity.

With  respect  to  the  development  of  PA-based  vaccines  and  therapeutics  such  as  VeloThrax™,  there  are  a  number  of  other  companies  in  preclinical  and
clinical development including Emergent, Pharmathene, Dynavax, Panacea Biotech, Paxvax, Elusys, and Pfenex.

Cangene, which was recently acquired by Emergent, is currently developing an anthrax immune globulin therapeutic based on plasma collected from military
personnel who have been vaccinated with BioThrax®. Human Genome Sciences is developing a monoclonal antibody to Bacillus  anthracis,  referred  to  as
ABthrax™, as a post-exposure therapeutic for anthrax infection. Elusys Therapeutics is developing a monoclonal antibody to Bacillus anthracis, known as
Anthim™, as a pre-exposure and post-exposure prophylaxis against anthrax infection, as well as an active treatment of the disease. Pharmathene and Medarex
are collaborating to develop a human antibody to anthrax, known as Valortim™. Bavarian Nordic is developing a multivalent combination vaccine against
both anthrax and smallpox.

The only potential competition to RiVax™ is being developed by the U.S. Army Medical Research Institute of Infectious Diseases, the DoD’s lead laboratory
for medical research to counter biological threats. Development of this product, known as RVEc™, is proceeding under a program led by Dr. Len Smith, who
has been working for many years to develop a ricin vaccine candidate. Similar to RiVax™, 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,  Aeolus  Pharmaceuticals,  Boulder
Biotechnology, RxBio, Inc., Avaxia Biologics, Exponential Biotherapies Inc., Osiris Therapeutics, Inc., ImmuneRegen BioSciences, Inc., Neumedicines, Inc.,
Cellerant  Therapeutics,  Onconova  Therapeutics,  Inc.,  Araim  Pharmaceuticals,  Inc.,  EVA  Pharmaceuticals,  Terapio,  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.

17

 
 
 
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’s 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  are  the  exclusive  licensee  of  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. 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.

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.

Recently, we have 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.

In addition to issued and pending patents, we also have “Orphan Drug” designations for SGX203 in the U.S. for pediatric Crohn’s disease, OrbeShield™ in
the U.S. for GI ARS, orBec® in the U.S. and Europe (E.U.) for GI GVHD, 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. 10 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 orBec®/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 $300,000 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 orBec® by the European Medicines Agency.

Additionally, in the event that the Company sublicenses its rights under this 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.

The term of this agreement expires upon the expiration of the licensed patent applications or patents. After five years from the date of the agreement, Dr.
McDonald has the right to terminate this 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.

ThermoVaxTM 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 filed on May 21, 2013 entitled “Method of Preparing an Immunologically-Active Adjuvant-Bound Dried Vaccine Composition.”
This patent and its corresponding foreign filings are pending and licensed to Soligenix by the UC and they address the use of adjuvants in conjunction with
vaccines that are formulated to resist thermal inactivation. 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 entitled: “Thermostable Vaccine Compositions and Methods of Preparing Same.”

19

 
 
 
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. Our license obligates us to pay $50,000 in annual license fees. Through this license, we have rights to the issued
patent number 7,175,848 entitled “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™.

VeloThrax™ License Option Agreement

In December of 2011, we optioned a license to the VeloThrax™ patent from the President and Fellows of Harvard College. VeloThrax™ is the subject of U.S.
patent No. 7,037,503, issued on May 2, 2006 and titled, “Compounds and Methods for the Treatment and Prevention of Bacterial Infection”, along with any
reissue, renewal, reexamination, substitution or extension thereof.

Intrexon Exclusive Channel Collaboration Agreement

On April 27, 2013, we entered into an exclusive channel collaboration agreement with Intrexon (the “Channel Agreement”) that governs an arrangement in
which  we  intend  to  use  Intrexon’s  advanced  human  antibody  discovery,  isolation  and  production  technologies  for  the  development  of  human  monoclonal
antibody therapies for a new biodefense application.  The target of the channel collaboration will be melioidosis, a potentially lethal disease caused by the
Gram-negative bacteria Burkholderia pseudomallei, which is endemic in Southeast Asia and Northern Australia.

The Channel Agreement grants us an exclusive worldwide license to use specified patents and other intellectual property of Intrexon in connection with the
research,  development,  use,  importing,  manufacture,  sale  and  offer  for  sale  of  products  for  the  treatment  of  melioidosis  through  the  use  of  exogenously
produced human recombinant monoclonal antibodies.

In  exchange  for  the  license,  we  paid  Intrexon  a  one-time  technology  access  fee  of  $1.5  million  in  common  stock.   Additionally,  the  Channel  Agreement
requires us to make certain milestone payments to Intrexon which could reach up to $7 million and to pay Intrexon royalty payments based upon sales of
products based upon Intrexon’s technology.

Research and Development Expenditure

We  spent  approximately  $5.1  million  and  $2.6  million  in  the  years  ended  December  31,  2013  and  2012,  respectively,  on  research  and  development.  The
amounts we spent on research and development per product during the years ended December 31, 2013, and 2012 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, 2013, we had 17 full-time employees, 7 of whom are MDs/PhDs.

Available Investor Information

We  file  electronically  with  the  Securities  and  Exchange  Commission  (“SEC”)  our  annual  reports  on  Form  10-K,  quarterly  reports  on  Form  10-Q,  current

Item 1A. Risk factors

You should carefully consider the risks, uncertainties and other factors described below before you decide whether to buy shares of our common stock. Any of
the factors could materially and adversely affect our business, financial condition, operating results and prospects and could negatively impact the market
price of our common stock. Below are the significant risks and uncertainties of which we are aware. 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.

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, 2013, had an accumulated deficit of approximately $132.3 million. We expect to
incur additional operating losses in the future and expect our cumulative losses to increase. As of December 31, 2013, we had approximately $5.9 million in
cash available. Based on our projected budgetary needs and funding from existing grants over the next two years and prior to making any sales to Lincoln
Park Capital Fund, LLC relating to the equity facility under the Common Stock Purchase Agreement, we expect to be able to maintain the current level of our
operations for at least the next twelve months.

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 several years. 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 and, 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
the grants and other administrative costs.

Our products are positioned for or are currently in clinical trials, and we have not yet generated any significant revenues from sales or licensing of them. From
inception through December 2013, we have expended approximately $51.8 million developing our current product candidates for pre-clinical research and
development and clinical trials, and we currently expect to spend at least $10.8 million over the next twelve months in connection with the development of
our therapeutic and vaccine products, licenses, employment agreements, and consulting agreements of which approximately $6.8 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.

21

 
 
 
 
 
 
 
If we are unable to develop our products 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.

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;

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 enter into arrangements or collaborations to manufacture and/or market 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.

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  U.S.,  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 and require 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.    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.  We cannot be sure that the results of later clinical trials would replicate the results of prior clinical trials and preclinical testing.  In
addition, we, the FDA or other regulatory authorities may suspend clinical trials at any time if it appears that 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.  For example, our confirmatory Phase 3
clinical trial for orBec® (oral BDP) in the treatment of GI GVHD was stopped on September 15, 2011 at the recommendation of an independent Data Safety
Monitoring Board (“DSMB”) as it was highly unlikely to achieve the predetermined end point of efficacy based on the interim results. Although no safety
concerns were raised by the DSMB, preliminary findings indicated that there were no significant differences between the orBec® group and placebo group for
the primary endpoint or for the pre-specified secondary endpoints. Given the outcome of the Phase 3 study, we terminated the development of orBec® for the
treatment  of  acute  GI  GVHD.  Although  we  hope  to  obtain  FDA  approval  for  oral  BDP  in  similar  indications,  such  as  treatment  of  chronic  GI  GVHD,
treatment of pediatric Crohn's disease acute radiation enteritis, and GI ARS, there can be no assurances that the FDA will ever approve oral BDP for market
launch in any of these indications.

22

 
 
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 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. 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.

We will be 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 cGMP or similar requirements that the FDA or foreign regulators establish. We, or our materials suppliers, may face manufacturing
or quality control problems causing product production and shipment delays or a situation where we or the supplier may not be able to maintain compliance
with  the  FDA’s  cGMP  requirements,  or  those  of  foreign  regulators,  necessary  to  continue  manufacturing  our  drug  substance.  Any  failure  to  comply  with
cGMP  requirements  or  other  FDA  or  foreign  regulatory  requirements  could  adversely  affect  our  clinical  research  activities  and  our  ability  to  market  and
develop our products.

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

We  do  not  have  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.

The technology on which our channel partnering arrangement with Intrexon is based on is early stage technology in the field of Melioidosis.

Our exclusive channel collaboration arrangement with Intrexon contemplates the use of Intrexon’s modular genetic engineering platform for the development
of active pharmaceutical ingredients and drug products targeting the biodefense countermeasure, melioidosis.  Such technology has a limited history of use in
the design and development of human therapeutic product candidates and may therefore involve unanticipated risks or delays.  Although we plan to leverage
Intrexon’s technology and scientific expertise to develop products for the treatment of melioidosis, an infectious disease caused by bacteria found in soil and
water, we may not be successful in developing and commercializing these products for a variety of reasons.  The risk factors set forth herein that apply to our
other  product  candidates,  which  are  in  various  stages  of  development,  also  apply  to  product  candidates  that  we  seek  to  develop  under  our  exclusive
partnership with Intrexon.

We will incur additional expenses in connection with our exclusive channel collaboration arrangement with Intrexon.

Pursuant  to  our  exclusive  channel  collaboration  with  Intrexon,  we  are  responsible  for  future  research  and  development  expenses  of  product  candidates
developed under such collaboration.  Although it is our intent to pursue government funding to support this development, we expect the level of our overall
research  and  development  expenses  going  forward  will  increase.    Because  our  collaboration  with  Intrexon  is  new,  we  have  yet  to  assume  development
responsibility  and  costs  associated  with  such  program.    In  addition,  because  development  activities  are  determined  pursuant  to  a  joint  steering  committee
comprised of representatives from Intrexon and our company, future development costs associated with this program may be difficult to anticipate and exceed
our expectations.  Our actual cash requirements may vary materially from our current expectations for a number of other factors that may include, but are not
limited to, unanticipated technical challenges, changes in the focus and direction of our development activities or adjustments necessitated by changes in the
competitive  landscape  in  which  we  operate.    If  we  are  unable  to  continue  to  financially  support  such  collaboration  due  to  lack  of  sufficient  government
funding  or  our  own  working  capital  constraints,  we  may  be  forced  to  delay  our  activities.    If  we  are  unable  to  obtain  funding,  we  may  be  forced  to  seek
licensing partners or discontinue development.

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.

25

 
 
 
 
 
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 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, and we entered into an exclusive channel
collaboration agreement with Intrexon pursuant to which we acquired a license to Intrexon’s advanced human antibody discovery, isolation, and production
technologies. 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.

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 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.

26

 
 
 
 
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 regarding
the breadth of claims allowed in biotechnology patents.

In addition, because patent applications in the U.S. are maintained in secrecy until 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 US Patent and Trademark Office 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.

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    seventeen  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  months,  there  has  been  substantial  volatility  in  financial  markets  due  at  least  in  part  to  the  uncertainty  with  regard  to  the  global  economic
environment  and  the  partial  government  shutdown  due  to  delays  in  increasing  the  U.S.  debt  limit  in  October  2013.  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.

27

 
 
 
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.

The financial and operational projections that we may make from time to time are subject to inherent risks.

The projections that our management may provide from time to time (including, but not limited to, those relating to potential market size, patient population,
clinical trial enrollment or data dates, and other financial or operational matters) reflect numerous assumptions made by management, including assumptions
with respect to our specific business as well as general business, economic, market and financial conditions and other matters, all of which are difficult to
predict and many of which are beyond our control.  Accordingly, there is a risk that the assumptions made in preparing the projections, or the projections
themselves, will prove inaccurate.  There will be differences between actual and projected results, and actual results may be materially different from those
contained in the projections.  The inclusion of the projections in (or incorporated by reference in) this Annual Report should not be regarded as an indication
that we or our management or representatives considered or consider the projections to be a reliable prediction of future events, and the projections should not
be relied upon as such.

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,  2013,  the  closing  stock  price  has  fluctuated  between  a  high  of  $2.39  per  share  to  a  low  of  $0.60  per  share.  As  of  March  21,  2014,  our
common stock closed at $2.41 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.  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.

28

 
 
 
If 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, 2013, we had a number of agreements or obligations that may result in dilution to investors. These include:

·   warrants to purchase a total of approximately 8,156,526 shares of our common stock at a current weighted average exercise price of approximately

$2.17; and
options to purchase approximately 2,051,511 shares of our common stock at a current weighted average exercise price of approximately $2.63.

·  

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.

29

 
 
 
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.

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.

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

We  currently  lease  approximately  5,250  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. On February 7, 2012, we entered into a lease agreement through March 31, 2015 for our existing office space.
The rent for the first 12 months is approximately $8,000 per month, or approximately $18.25 per square foot on an annualized basis. This rent increases to
approximately $8,310 per month, or approximately $19.00 per square foot on an annualized basis, for the remaining 24 months. 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.

Dividends

We have never declared nor paid any cash dividends, and currently intend to retain all our cash and any earnings for use in our business and, therefore, do not
anticipate  paying  any  cash  dividends  in  the  foreseeable  future.  Any  future  determination  to  pay  cash  dividends  will  be  at  the  discretion  of  the  Board  of
Directors and will be dependent upon our consolidated financial condition, results of operations, capital requirements and such other factors as the Board of
Directors deems relevant.

Our Business Overview

Soligenix, Inc. was incorporated in Delaware in 1987. We are clinical stage biopharmaceutical company that is focused on developing products to treat the
life-threatening  side  effects  of  cancer  treatments  and  serious  gastrointestinal  diseases  where  there  remains  an  unmet  medical  need,  as  well  as  developing
several biodefense vaccines and therapeutics. We maintain two active business segments: BioTherapeutics and Vaccines/BioDefense.

Our  BioTherapeutics  business  segment 
the
prevention/treatment of gastrointestinal (“GI”) disorders characterized by severe inflammation, including pediatric Crohn’s disease (SGX203), acute radiation
enteritis (SGX201) and chronic Graft-versus-Host disease (orBec®), as well as developing our novel innate defense regulator (“IDR”) technology (SGX942)
for the treatment of oral mucositis.

is  developing  proprietary  formulations  of  oral  beclomethasone  17,21-dipropionate  (“BDP”)  for 

Our  Vaccines/BioDefense  business  segment  includes  RiVax™,  our  ricin  toxin  vaccine,  and  VeloThrax™,  our  anthrax  vaccine,  and  OrbeShield™,  our
gastrointestinal  acute  radiation  syndrome  (“GI  ARS”)  therapeutic  and  SGX943,  and  our  melioidosis  therapeutic.  The  advanced  development  of  these
programs will be supported by our existing and on-going government contracts and grants, which include our National Institutes of Health (“NIH”) grant for
our  heat  stabilization  technology  ThermoVax™  and  contracts  from  the  Biomedical  Advanced  Research  and  Development  Authority  (“BARDA”)  and  the
National Institute of Allergy and Infectious Diseases (“NIAID”) for GI ARS.  Additionally, we entered into a global and exclusive channel collaboration with
Intrexon  Corporation  (“Intrexon”)  through  which  we  intend  to  develop  and  commercialize  a  human  monoclonal  antibody  therapy  (SGX101)  to  treat
melioidosis.

An outline of our business strategy follows:

·  
·  
·  

Conduct a Phase 2 clinical trial of SGX942 for the treatment of oral mucositis in head and neck cancer;
Initiate a Phase 2/3 clinical trial of oral BDP, known as SGX203 for the treatment of pediatric Crohn’s disease;
Evaluate the effectiveness of oral BDP in other therapeutic indications involving inflammatory conditions of the gastrointestinal (“GI”) tract such as
prevention of acute radiation enteritis, prevention of acute radiation syndrome, and treatment of chronic graft-versus-host disease (“GVHD”);
·   Develop RiVax™ and VeloThrax™ in combination with our proprietary vaccine heat stabilization technology, known as ThermoVax™, 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, an example of which is our collaboration with Intrexon.

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.

32

 
 
 
 
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 rights for our current products 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 industrial partners. These rights can also be sold or sub-
licensed  as  part  of  our  strategy  to  partner  our  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, maintain and perhaps extending the lives of the
patents. We capitalize such costs and amortize intangibles 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, 2013. 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.

33

 
 
 
 
The carrying amounts reported in the consolidated balance sheet for cash and cash equivalents, accounts receivable, accounts payable and accrued expenses
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 offering were accounted for as derivatives.

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  stock  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.

Revenue Recognition

Principally our revenues are generated from government contracts and grants. Recording of revenue is applied in accordance with FASB ASC 605, Revenue
Recognition, ASC 605-25 and/or Accounting Standard Update, ASU, 2009-13, Revenue Recognition – Multiple Element Arrangements. The revenue from
government contracts and grants is based upon subcontractor costs and internal costs incurred that are specifically covered by the grants, plus a facilities and
administrative rate that provides funding for overhead expenses. These revenues are recognized when expenses have been incurred by subcontractors or when
we incur internal expenses that are related to the grant.

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 warrants’ provisions 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 an equity instrument for 2013 and
2012.

Stock-Based Compensation

Stock  options  are  issued  with  an  exercise  price  equal  to  the  market  price  on  the  date  of  issuance.  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% immediately as of 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. Stock-based
compensation expense recognized during the period is based on the fair value of the portion of share-based payment awards that is ultimately expected to vest
during the period. Typically these instruments vest upon issuance and therefore the entire stock compensation expense is recognized upon issuance to the
vendors and/or consultants

34

 
 
 
 
We determine stock-based compensation expense for options, warrants and shares of common stock granted to non-employees in accordance with FASB ASC
718, Stock Compensation, 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.  Stock-based  compensation  expense  recognized  during  the  period  is  based  on  the  value  of  the
portion of share-based payment awards that is ultimately expected to vest during the period.

Material Changes in Results of Operations

Year Ended December 31, 2013 Compared to 2012

For the year ended December 31, 2013, we had a net loss of $10,058,996 as compared to a net loss of $4,163,008 for the prior year, representing an increased
loss of $5,895,988 or 142%. Included in the net loss for December 31, 2013 is a non-cash charge of $3,654,770 which represents the change in the fair value
of the warrant liability related to warrants issued in connection with our registered public offering. During the second quarter of 2013, we entered into an
exclusive  channel  collaboration  agreement  with  Intrexon  Corporation  under  which  we  issued  common  stock  with  a  value  of  $1,500,000  which  was
recognized  as  a  research  and  development  expense.   Additionally,  we  initiated  a  Phase  2  clinical  trial  with  SGX942  and  continued  efforts  for  initiating  a
clinical trial with SGX203.

For the year ended December 31, 2013, revenues and associated costs relate to government grants and contracts  awarded in support of the development of
ThermoVax™,  GI-ARS,  orBec®  and  OrbeShield™  in  GI  ARS.  For  the  year  ended  December  31,  2013,  we  had  revenues  of  $3,224,152  as  compared  to
$3,144,620 for the prior year, representing an increase of $79,532. The slight increase in revenues was a result of initiating the OrbeShield™ contracts during
the fourth quarter of 2013 offset by minor delays in ThermoVax™ grant.

We  incurred  costs  related  to  grant  and  contract  revenue  in  the  year  ended  December  31,  2013  and  2012  of  $2,544,285  and  $2,593,075,  respectively,
representing a decrease of $48,790, or 2%. These costs primarily relate to payments made to subcontractors in connection with research performed pursuant
to 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, 2013 was $679,867 as compared to $551,545 for the prior year, representing an increase of $128,322 or
23%. This increase is due primarily to the OrbeShield™ contracts which provide a management fee and higher negotiated reimbursement for fixed overhead.

Research and development spending increased by $2,461,938 or 94%, to $5,071,179 for the year ended December 31, 2013 as compared to $2,609,241 for the
prior year. This increase is related to the exclusive channel collaboration agreement with Intrexon Corporation under which we issued common stock with a
value of $1,500,000, the initiation of the Phase 2 clinical trial with SGX942 and continued efforts for initiating a clinical trial with SGX203.

General and administrative expenses increased by $132,258, or 5%, to $2,765,230 for the year ended December 31, 2013, as compared to $2,632,972 for the
prior  year.  This  increase  is  primarily  related  to  non-cash  expenses  for  stock  based  compensation  from  stock  options  issued  to  existing  and  newly  hired
employees.

Other income (expense) for the year ended December 31, 2013 was $(3,652,810) as compared to $6,202 for the prior year. The increased expense is primarily
related to a non-cash charge of $3,654,770 which represents the change in the fair value of the warrant liability related to warrants issued in connection with
our registered public offering.

During  the  year  ended  December  31,  2013,  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 (“NOL”) carryforwards to other New Jersey-based corporate taxpayers
based in New Jersey, we sold New Jersey NOL carryforwards, resulting in the recognition of $750,356 of income tax benefit, net of transaction costs. There
can be no assurance as to the continuation or magnitude of this program in future years.

35

 
 
 
 
Business Segments

We maintain two active business segments for the year ended December 31, 2013 and December 31, 2012: Vaccines/BioDefense and BioTherapeutics.

Revenues for the Vaccines/BioDefense business segment for the year ended December 31, 2013 were $3,003,822 as compared to $2,919,677 for the year
ended December 31, 2012, representing an increase of $84,145 or 3%. The increases in revenues were a result of initiating the OrbeShield™ contracts during
the  fourth  quarter  of  2013.  Revenues  for  the  BioTherapeutics  business  segment  for  the  year  ended  December  31,  2013  were  $220,330  as  compared  to
$224,943 for the year ended December 31, 2012, representing a slight decrease of $4,613. This decrease is primarily related to the expiration in August 2013
of a 3-year orphan grant received in 2010.

Loss from operations for the Vaccines/BioDefense business segment for the year ended December 31, 2013 was $1,666,130 as compared to $33,636 for the
year ended December 31, 2012, representing an increased loss of $1,632,494. This increase is primarily attributable to the exclusive channel collaboration
agreement  with  Intrexon  Corporation  under  which  we  issued  common  stock  with  a  value  of  $1,500,000.  Loss  from  operations  for  the  BioTherapeutics
business segment for the year ended December 31, 2013 was $3,069,998 as compared to $2,203,721 for the year ended December 31, 2012, representing an
increase of $866,277. This increased loss is due primarily due to the initiation of the Phase 2 clinical trial with SGX942, continued efforts for initiating a
clinical trial with SGX203 and increased headcount to support these programs.

Amortization and depreciation expense for the Vaccines/BioDefense business segment for the year ended December 31, 2013 was $37,981 as compared to
$38,589  for  the  year  ended  December  31,  2012.    Amortization  and  depreciation  expense  for  the  BioTherapeutics  business  segment  for  the  year  ended
December 31, 2013 was $190,033 as compared to $190,003 for the year ended December 31, 2012.

Financial Condition and Liquidity

Cash and Working Capital

As of December 31, 2013, we had cash and cash equivalents of $5,856,242 as compared to $3,356,380 as of December 31, 2012, representing an increase of
$2,499,862  or  74%.  As  of  December  31,  2013,  we  had  working  capital  of  $5,855,046,  which  excludes  a  non-cash  warrant  liability  of  $8,281,247,  as
compared to working capital of $2,682,383 as of December 31, 2012, representing an increase of $3,172,663 or 118%. The increase in working capital was
primarily the result of net proceeds of $6,738,588 received from our registered public offering, Lincoln Park equity line and proceeds of $235,975 from the
exercise of stock options and warrants offset by the cash used in operating and investing activities over the period. For the year ended December 31, 2013, the
Company’s cash used in operating activities was $4,456,973 as compared to $2,635,533 for the same period in 2012, representing an increase of $1,821,440.
This increase was attributable to the initiation of clinical trials with SGX942 for the treatment of oral mucositis, preparation for clinical trials with SGX203
for the treatment of pediatric Crohn’s disease, increased headcount to support these programs and the delay in receiving the proceeds related to the State of
New Jersey Technology Business Tax Certificate Transfer Program for 2013, which were received prior to year end in the prior year.

Based on the Company’s current rate of cash outflows, cash on hand, proceeds from government grant and contract programs, proceeds available from the
Lincoln Park equity line 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.

36

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

·   We have up to $33.2 million in active contract and grant funding still available to support our associated research programs in 2014 and beyond. We

plan to submit additional 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 its Technology Business Tax Certificate Transfer Program. Based on the receipt of
$750,356 in proceeds from the sale of NJ NOL in 2013, we expect to participate in this program during 2014 and beyond as the program is available;
and

·   We may seek additional capital in the private and/or public equity markets 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  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 $10.8 million before any grant reimbursements, of
which $3.9 million relates to the BioTherapeutics business and $6.9 million relates to the Vaccines/BioDefense business. We anticipate contract and grant
reimbursements  in  the  next  12  months  of  approximately  $6.8  million  to  offset  research  and  development  expenses  in  the  Vaccines/BioDefense  business
segment.

The  Company  has  commitments  of  approximately  $400,000  at  December  31,  2013  for  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.

On  February  7,  2012,  we  entered  into  a  lease  agreement  through  March  31,  2015  for  our  existing  office  space.  The  rent  for  the  first  12  months  is
approximately $8,000 per month, or approximately $18.25 per square foot. This rent increases to approximately $8,310 per month, or approximately $19.00
per square foot on, for the remaining 24 months. Rent expense is recognized on a straight-line basis.

In February 2007, our Board of Directors authorized the issuance of the following number of shares to each of Dr. Schaber and Dr. Brey immediately prior to
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: 50,000 common shares to Dr. Schaber; and
10,000 common shares to Dr. Brey. The amended agreement with Dr. Schaber includes our obligation to issue shares if such event occurs.

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

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

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

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

Management’s Annual Report on Internal Control over Financial Reporting

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

·  

·  

·  

pertain  to  the  maintenance  of  records  that  in  reasonable  detail  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the
Company;
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally
accepted  accounting  principles,  and  that  receipts  and  expenditures  of  the  Company  are  being  made  only  in  accordance  with  authorizations  of
management and directors of the Company; and
provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that
could have a material effect on the financial statements.

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,  2013.  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.

Based on our assessment, management has concluded that, as of December 31, 2013, 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.

Board Leadership Structure

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

Messrs. Brownlie, Lapointe 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 meeting 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, provides the Chairman with input regarding agenda items for Board of Directors and Committee meetings, and coordinates
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 Securities Exchange Act of 1934.

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, 2013, our officers, directors and significant stockholders have timely filed the appropriate form under Section 16(a) of the Exchange
Act.

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
http://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.

Audit Committee Financial Expert

We have an audit committee comprised of Messrs. Brownlie (Chair) and Lapointe and Dr. Rubin. The board of directors has determined that Mr. Brownlie
qualifies as an “audit committee financial expert,” as defined under the rules of the Securities and Exchange Commission. The 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.

The board of directors has determined that Messrs. Brownlie and Lapointe and Dr. Rubin are “independent directors” within the meaning of The NASDAQ
Stock Market LLC (“Nasdaq”) corporate governance rules and the regulations under the Securities Exchange Act of 1934 (“Exchange Act”) applicable to
audit committees.

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. This 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 Dr. Schaber
and his dependants. No unvested options shall vest beyond the termination date. Dr. Schaber’s monetary compensation (base salary of $300,000 and bonus of

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

remainder  of  their  term  and  become  the  property  of  Dr.  Schaber’s  immediate  family.  This  agreement  automatically  renewed  in  December  2013  for  an
additional term of three years.

1 Directors  who  are  compensated  as  full-time  employees  receive  no  additional  compensation  for  service  on  our  Board  of  Directors.  Each  independent
director  who  is  not  a  full-time  employee  is  paid  $35,000  annually,  on  a  prorated  basis,  for  their  service  on  our  Board  of  Directors,  the  chairman  of
our Audit  Committee  is  paid  $15,000  annually,  on  a  prorated  basis,  and  the  chairmen  of  our  Compensation  and  Nominating  Committees  will  be  paid
$10,000 annually, on a prorated basis. Additionally, Audit Committee members are paid $7,500 annually and Compensation and Nominating Committee
members are paid $5,000 annually. This compensation is paid quarterly.

2 We maintain a stock option grant program pursuant to the nonqualified stock option plan, whereby members of our Board of Directors or its committees
who  are  not  full-time  employees  receive  an  initial  grant  of  fully  vested  options  to  purchase  15,000  shares  of  common  stock.  Upon  re-election  to  the
Board, each Board member will receive stock options with a value of $30,000, calculated using the closing price of the common stock on the trading day
prior to the date of the annual meeting of the Company’s stockholders, which vest at the rate of 25% per quarter, commencing with the first quarter after
each annual meeting of stockholders.

 3 Mr. Marco Brughera was appointed to our Board of Directors on October 21, 2013.

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.

In  December  2005,  our  Board  of  Directors  approved  the  2005  Equity  Incentive  Plan,  which  was  approved  by  stockholders  on  December  29,  2005.  In

common stock available for issuance under the plan by 750,000 shares, bringing the total shares reserved for issuance under the plan to 1,750,000 shares. In

Item 13. Certain Relationships and Related Transactions and Director Independence

Related Party Transactions

Other than the employment agreements and compensation paid to our directors, we did not engage in any transactions with related
parties since January 1, 2011.  For a discussion of our employment agreements and compensation paid to our directors, see “Item
11. Executive Compensation.”

Director Independence

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

Soligenix, Inc. and Subsidiaries
Notes to Consolidated Financial Statements

Note 1. Nature of Business

Basis of Presentation

Soligenix, Inc. (the “Company”) is a clinical stage biopharmaceutical company that was incorporated in 1987 and is focused on developing products to treat
the life-threatening side effects of cancer treatments and serious gastrointestinal diseases where there remains an unmet medical need, as well as developing
several biodefense vaccines and therapeutics. The Company maintains two active business segments: BioTherapeutics and Vaccines/BioDefense. Soligenix’s
BioTherapeutics business segment is developing 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), acute radiation enteritis (SGX201) and
chronic Graft-versus-Host disease (orBec®), as well as developing our novel innate defense regulator (“IDR”) technology (SGX942) for the treatment of oral
mucositis.  The Vaccines/BioDefense business segment includes RiVax™, a ricin toxin vaccine, and VeloThrax™, an anthrax vaccine, and OrbeShield™, a
gastrointestinal acute radiation syndrome (“GI ARS”) program and SGX943, a melioidosis therapeutic. The advanced development of these programs will be
supported by existing and on-going government contracts and grants, which include the National Institutes of Health (“NIH”) grant for the heat stabilization
technology ThermoVax™  and  contracts  from  the  Biomedical  Advanced  Research  and  Development  Authority  (“BARDA”)  and  the  National  Institute  of
Allergy and Infectious Diseases (“NIAID”) for GI ARS.  Additionally, the Company entered into a global and exclusive channel collaboration with Intrexon
Corporation (“Intrexon”) through which it intends to develop and commercialize a human monoclonal antibody therapy (SGX101) to treat melioidosis.

The  Company  generates  revenues  under  four  grants  from  the  NIH  and  government  contracts  from  the  Biomedical  Advanced  Research  and  Development
Authority (“BARDA”) and the National Institute of Allergy and Infectious Diseases (“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 FDA regulations, litigation, and product liability.

Liquidity

As of December 31, 2013, the Company had cash and cash equivalents of $5,856,242 as compared to $3,356,380 as of December 31, 2012, representing an
increase of $2,499,862 or 74%. As of December 31, 2013, the Company had working capital of $5,855,046, which excludes a non-cash warrant liability of
$8,281,247,  as  compared  to  working  capital  of  $2,682,383  as  of  December  31,  2012,  representing  an  increase  of  $3,172,663  or  118%.  The  increase  in
working capital was primarily the result of net proceeds of $6,738,588 received from our registered public offering, Lincoln Park equity line and proceeds of
$235,975  from  the  exercise  of  stock  options  and  warrants  offset  primarily  by  the  cash  used  in  operating  activities  over  the  period.  For  the  year  ended
December 31, 2013, the Company’s cash used in operating activities was $4,456,973 as compared to $2,635,533 for the same period in 2012, representing an
increase  of  $1,821,440.  This  increase  was  attributable  to  the  initiation  of  clinical  trials  with  SGX942  for  the  treatment  of  oral  mucositis,  preparation  for
clinical  trials  with  SGX203  for  the  treatment  of  pediatric  Crohn’s  disease,  increased  headcount  to  support  these  programs  and  the  delay  in  receiving  the
proceeds related to the State of New Jersey Technology Business Tax Certificate Transfer Program for 2013, which were received prior to year end in the
prior year.

Based on the Company’s current rate of cash outflows, cash on hand, proceeds from its grant programs, proceeds expected from the Lincoln Park transaction
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:

·
·
·

·

·
·

·
·

Conduct a Phase 2 clinical trial of SGX942 for the treatment of oral mucositis in head and neck cancer;
Initiate Phase 2/3 clinical trial of oral BDP, known as SGX203, for the treatment of pediatric Crohn’s disease;
Evaluate  the  effectiveness  of  oral  BDP  in  other  therapeutic  indications  involving  inflammatory  conditions  of  the  GI  tract  such  as  prevention  of  acute
radiation enteritis, prevention of acute radiation syndrome, and treatment of chronic GVHD;
Develop RiVax™ and VeloThrax™ in combination with our proprietary vaccine heat stabilization technology, known as ThermoVax™, 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 GIARS;
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, an example of which is our collaboration with Intrexon.

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

·

·

·

·

The Company has up to $33.2 million in active grant funding still available to support its associated research programs through 2014 and beyond. The
Company plans to submit additional 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 Losses (“NOLs”) sales in the State of New Jersey pursuant to its Technology Business Tax Certificate Transfer
Program. Based on the receipt, in January 2014, of $750,356 in proceeds pursuant to NOLs sales in 2013, the Company expects to participate in the
program during 2014 and beyond; and
The  Company  may  seek  additional  capital  in  the  private  and/or  public  equity  markets  to  continue  its  operations,  respond  to  competitive  pressures,
develop  new  products  and  services,  and  to  support  new  strategic  partnerships.  The  Company  is  currently  evaluating  additional  equity  financing
opportunities 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.

Grants and Contracts Receivable

Grants and contracts receivable consist of unbilled amounts due from various grants from the NIH and contracts from BARDA and NIAID 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.

F-7

 
 
 
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 industrial 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  and  perhaps
extending the lives of the patents. The Company capitalizes such costs and amortizes intangibles over their expected useful life – generally a period of 11 to
16 years.

The Company did not capitalize any patent related costs during the year ended December 31, 2013 or 2012.

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, 2013 or 2012.

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, 2013. 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.

F-8

 
 
 
 
 
 
The carrying amounts reported in the consolidated balance sheet for cash and cash equivalents, accounts receivable, accounts payable and accrued expenses
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  offering  were  accounted  for  as  derivatives.  See  Note  4,  Warrant
Liabilities.

Revenue Recognition

Principally the Company’s revenues are generated from government contracts and grants. Recording of revenue is applied in accordance with FASB ASC
605, Revenue Recognition, ASC 605-25 and/or Accounting Standard Update, ASU, 2009-13, Revenue Recognition – Multiple Element Arrangements. The
revenue from government contracts and grants is based upon subcontractor costs and internal costs incurred that are specifically covered by the grants, plus a
facilities and administrative rate that provides funding for overhead expenses and management fee. These revenues are recognized when expenses have been
incurred by subcontractors or when the Company incurs 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,  stock  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.

Stock-Based Compensation

Stock  options  are  issued  with  an  exercise  price  equal  to  the  market  price  on  the  date  of  issuance.  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% immediately as of 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. Stock-based
compensation expense recognized during the period is based on the fair value of the portion of share-based payment awards that is ultimately expected to vest
during the period. Typically these instruments vest upon issuance and therefore the entire stock compensation expense is recognized upon issuance to the
vendors and/or consultants

Stock  compensation  expense  for  options,  warrants  and  shares  of  common  stock  granted  to  non-employees  has  been  determined  in  accordance  with  FASB
ASC  718,  Stock  Compensation,  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.  For  options  that  vest  over  future  periods,  the  fair  value  of  options  granted  to  non-employee
directors is amortized as the options vest.

F-9

 
 
 
 
The  fair  value  of  options  in  accordance  with  FASB  ASC  718,  Stock Compensation,  was  estimated  using  the  Black-Scholes  option-pricing  model  and  the
following assumptions:

·
·
·
·
·

a dividend yield of 0%;
an expected life of 4 years;
volatilities of 136% - 167% and 160% for 2013 and 2012, respectively;
forfeitures at a rate of 12%; and
risk-free interest rates of 0.96% to 1.17% and 0.51% for 2013 and 2012, respectively.

The fair value of each option grant made during 2013 and 2012 was estimated on the date of each grant using the Black-Scholes option pricing model and
amortized ratably over the option’s 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,  2013  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  2013  and  2012.  Additionally,  the  Company  has  not
recorded an asset for unrecognized tax benefits or a liability for uncertain tax positions at December 31, 2013 and 2012. Tax years beginning in 2011 for
federal purposes are generally subject to examination by taxing authorities, although net operating losses from those years are subject to examinations and
adjustments for at least three years following the year in which the tax attributes are utilized.

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. No options and warrants were included in the 2013 and 2012 computations of diluted earnings per share because their effect would be anti-dilutive
as a result of losses or options and warrants for which the strike price exceeds the quoted market value at period end.

Company’s stock options and warrants outstanding at December 31, 2013 were $2.63 and $2.17 per share, respectively. No options or warrants were included
in the 2013 and 2012 computations of diluted earnings per share because their effect would be anti-dilutive as a result of losses in each of those years.

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, stock options and recovery of the useful life of intangibles that affect the reported amounts in the financial
statements and accompanying notes. Actual results could differ from those estimates.

Note 4. Warrant Liabilities

Warrants issued in connection with the Company’s registered public offering contain provisions that protect holders from a decline in the issue price of its
common stock (or “down-round” provisions) and contain net settlement provisions. The Company accounts for these warrants as liabilities instead of equity.
Down-round provisions reduce the exercise or conversion price of a warrant if a 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.

The Company recognizes these warrants as liabilities at their fair value on the date of grant and remeasures them at 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. The
initial warrant liability recognized on the related warrants totaled $4,827,788, which was based on the June 25, 2013 closing price of a share of our common
stock as reported on OTC Markets of $0.96. On December 31, 2013, the closing price of our common stock as reported on OTC Markets was $1.80. Due to
the fluctuations in the market value of our common stock from June 25, 2013 through December 31, 2013, we recognized a non-cash charge of $3,654,770
for the change in the fair value of the warrant liability during the year ended December 31, 2013.

The assumptions used in connection with the valuation of warrants issued utilizing the Monte Carlo method were as follows:

Number of shares underlying the warrants
Exercise price
Volatility
Risk-free interest rate
Expected dividend yield
Expected warrant life (years)

At December 31, 2013, the Company had NOL carry forwards of approximately $80,793,000 for federal tax purposes and approximately $5,599,000 of New
Jersey NOL carry forwards remaining after the sale of unused net operating loss carry forwards, portions of which are currently expiring each year through
2033. In addition, the Company has $2,986,000 of various tax credits that expire from 2013 to 2033. The Company may be able to utilize their 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.  The
Company is no longer subject to Federal income tax assessment for years before 2011 for Federal and 2010 for New Jersey income tax assessment. However,
since the Company has incurred net operating losses in every tax year since inception, all its income tax returns are subject to examination and adjustments by
the Internal Revenue Service for at least three years following the year in which the tax attributes are utilized.

The net change in the valuation allowance for the years ended December 31, 2013 and 2012 was an increase of approximately $1,887,000 and $1,949,000,
respectively,  resulting  primarily  from  net  operating  losses  expiring  and  generated.  As  a  result  of  the  Company’s  continuing  tax  losses,  the  Company  has
recorded a full valuation allowance against a net deferred tax asset.

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, 2013 and 2012 was as follows:

Income tax loss at federal statutory rate
State tax benefits, plus sale of NJ NOLs, net of federal benefit

During the years ended December 31, 2013 and 2012, 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
based in New Jersey, the Company sold New Jersey net operating loss carryforwards, resulting in the recognition of $750,356 and $521,458 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.

The  Company  follows  FASB  ASC  740-10,  Uncertainty  in  Income  Taxes.  The  Company  recognizes  interest  and  penalties  associated  with  uncertain  tax
positions as a component of income tax expense. The Company does not expect that there will be any amounts of unrecognized tax benefits in the next 12
months. This standard prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position
taken or expected to be taken in a tax return. The Company did not have any unrecognized tax benefits or a liability for uncertain tax positions at December
31, 2013 and 2012. The Company does not expect to have any unrecognized tax benefits within the next twelve months. 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 2013 and 2012.

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 $10.0 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 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.

As part of the agreement, the Company received gross proceeds of $600,000 for the issuance of 383,370 shares of common stock to Lincoln Park. Associated
costs of $71,949 were incurred resulting in net proceeds of $528,051.

Note 7. Stock Option Plans and Warrants to Purchase Common Stock

Stock Option Plans

The Amended and Restated 1995 Omnibus Plan was replaced by the 2005 Equity Incentive Plan and is divided into four separate equity programs:

1)  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,

2)  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,

3)  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

4)  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”) is divided into four separate equity programs:

1)  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,

2)  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,

3)  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

4)  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.

As  of  December  31,  2013,  there  were  1,549,693  options  exercisable  with  a  weighted  average  exercise  price  of  $3.01,  a  weighted  average  remaining
contractual term of 6.4 years and an intrinsic value of $712,000.  As of December 31, 2013, there were 2,051,511 options outstanding and expected to vest
with a weighted average exercise price of $2.63, weighted average remaining term of 7.3 years and an intrinsic value of $1,157,000.  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, 2013
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, 2013.  This amount changes based on the fair market value of our common stock.

The Company awarded 791,100 and 100,000 stock options to new employees and new and existing Board members during 2013 and 2012, respectively. In
2013, under the 2005 Equity Incentive plan, 723,000 option grants were issued to employees and 68,100 option grants were issued to Board members.

At  December  31,  2013  and  2012,  the  Company  had  deposits  in  major  financial  institutions  that  exceeded  the  amount  under  protection  by  the  Securities
Investor Protection Corporation (“SIPC”). Currently, the Company is covered up to $1,000,000 by the SIPC. The excess amounts at December 31, 2013 and
2012 were $4,856,242 and $2,356,380, respectively.

Note 9. Commitments and Contingencies

The  Company  has  commitments  of  approximately  $400,000  at  December  31,  2013  for  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.

On  April  27,  2013,  the  Company  entered  into  an  exclusive  channel  collaboration  agreement  with  Intrexon  (the  “Channel  Agreement”)  to  use  Intrexon’s
advanced  human  antibody  discovery,  isolation  and  production  technologies  for  the  development  of  human  monoclonal  antibody  therapies  for  a  new
biodefense application targeting melioidosis.  The Channel Agreement grants an exclusive worldwide license to use specified patents and other intellectual
property  of  Intrexon  in  connection  with  the  research,  development,  use,  importing,  manufacture,  sale  and  offer  for  sale  of  products  for  the  treatment  of
melioidosis  through  the  use  of  exogenously  produced  human  recombinant  monoclonal  antibodies.  The  Channel  Agreement,  upon  clinical  or
commercialization success, may require the payment of certain milestones up to $7 million, if and when achieved.

On  February  7,  2012,  the  Company  entered  into  a  lease  agreement  through  March  31,  2015  for  existing  office  space.  The  rent  for  the  first  12  months  is
approximately $8,000 per month, or approximately $18.25 per square foot. This rent increases to approximately $8,310 per month, or approximately $19.00
per square foot, for the remaining 24 months.

In  February  2007,  the  Company’s  Board  of  Directors  authorized  the  issuance  of  the  following  number  of  shares  to  each  of  Dr.  Schaber  and  Dr.  Brey
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:  50,000
common shares to Dr. Schaber and 10,000 common shares to Dr. Brey. The amended agreement with Dr. Schaber includes its 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. On February 15, 2012, Mr. Myrianthopoulos’ employment agreement was terminated. The Company recognized an expense of $95,625 at
March 31, 2012 and at December 31, 2012 there are no severance and healthcare benefits due to Mr. Myrianthopoulos. In connection with the termination of
Mr. Myrianthopoulos’ employment agreement, we accelerated the vesting of options to purchase 53,908 shares of common stock and Mr. Myrianthopoulos
forfeited  options  to  purchase  72,500  shares  of  common  stock,  resulting  in  Mr.  Myrianthopoulos  holding  vested  options  to  purchase  192,500  shares  of
common stock with expiration dates ranging from November 14, 2012 to November 30, 2021. In connection with the acceleration of vesting, the Company
recognized $68,032 of stock-based compensation expense during the year ended December 31, 2012.

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

Soligenix, Inc.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

We have audited the accompanying consolidated balance sheets of Soligenix, Inc. and subsidiaries (the “Company”) as of December 31, 2013 and 2012, and
the  related  consolidated  statements  of  operations,  shareholders’  equity  (deficiency),  and  cash  flows  for  each  of  the  years  in  the  two-year  period  ended
December  31,  2013.   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, 2013, and the consolidated results of their operations and their cash flows for each of the years in the two-year period ended
December 31, 2013, in conformity with accounting principles generally accepted in the United States of America.
