Item 1. Business.

General

RegeneRx  Biopharmaceuticals,  Inc.  (“RegeneRx”  or  the  “Company”)  (OTCQB:RGRX)  is  a  biopharmaceutical  company  focused  on  the
development of a novel therapeutic peptide, Thymosin beta 4, or Tß4, for tissue and organ protection, repair, and regeneration. We have formulated Tß4 into
three distinct product candidates in clinical development:

•   RGN-259, a preservative-free topical eye drop for regeneration of corneal tissues damaged by injury, disease or other pathology;

•   RGN-352, an injectable formulation to treat cardiovascular diseases, central and peripheral nervous system diseases, and other medical indications

that may be treated by systemic administration; and

•   RGN-137, a topical gel for dermal wounds and reduction of scar tissue.

We are continuing strategic partnership discussions with biotechnology and pharmaceutical companies regarding the further clinical development of

all of our product candidates.

Current Financial Status

On February 27, 2019, we sold a series of convertible promissory notes to management, the Company’s Board of Directors and accredited investors,
including Essetifin S.p.A., our largest shareholder. The sale of the notes will result in gross proceeds to the Company of $1,300,000 over two closings. The
first closing in the amount of $650,000 occurred on February 27th and the second closing, also in the amount of $650,000 will occur within three days of the
Company providing notice of the enrollment of the first patent in the ARISE-3 clinical trial in DES sponsored by ReGenTree. ReGenTree has informed us
that they now expect the ARISE-3 clinical trial to occur in the second quarter of 2019. Because the Company does not control the timing of the ARISE-3
clinical trial, we cannot be certain that this timing is correct or that it may not change. The notes contain a $0.12 conversion price and the purchasers also
received a warrant exercisable at $0.18 to purchase additional shares of common stock equal to 75% of the number of shares into which each note is initially
convertible. At present, with the receipt of the sale proceeds from the first closing, coupled with the anticipated proceeds from the second closing, we will
have sufficient cash to fund planned operations through the first quarter of 2020. We continuously monitor our cash use as well as the clinical timelines.

We continue to evaluate options including the licensing of additional rights to commercialize our clinical products as well as raising capital through
the  capital  markets.  However,  our  ability  to  raise  additional  capital  raises  significant  concerns  about  our  ability  to  continue  as  a  going  concern.  Since
inception,  and  through  December  31,  2018,  we  have  an  accumulated  deficit  of  $106  million  and  we  had  cash  and  cash  equivalents  of  $237,261  as  of
December 31, 2018. We anticipate incurring additional operating losses in the future as we continue to explore the potential clinical benefits of Tß4-based
product candidates over multiple indications. We have entered into a series of strategic partnerships under licensing and joint venture agreements where our
partners are responsible for advancing development of our product candidates by sponsoring multiple clinical trials.

On March 2, 2018, we entered into a warrant reprice, exercise and issuance agreement (the “Reprice Agreement”) with the holders of the warrants
issued in the 2016 Offering. Under the terms of the Reprice Agreement, in consideration of the holders exercising in full all of the 2016 Offering warrants the
exercise price per share of the warrants was reduced to $0.20 per share. In addition, and as further consideration, we issued to the holders of the 2016 Offering
3,860,294 new warrants with an exercise price of $0.2301 per share. We received gross proceeds of approximately $1,029,000 pursuant to the exercise and
issued 5,147,059 shares of common stock. Pursuant to the terms of the Reprice Agreement the exercise price of the new warrants was reduced from $0.2301
to $0.125 as a result of the March 2019 note sale.

Current Clinical Status

In  January  2015,  we  entered  into  a  Joint  Venture  Agreement  with  GtreeBNT  whereby  we  created  ReGenTree  LLC,  (“ReGenTree”  or  “Joint
Venture”,  jointly  owned  by  us  and  GtreeBNT,  which  will  commercialize  RGN-259  for  treatment  of  dry  eye  and  neurotrophic  keratopathy,  an  orphan
indication in the United States. We are entitled to royalties as a percentage of net sales ranging from single digits to low-double digits based on the medical
indications approved and whether the Joint Venture commercializes products directly or through a third party. RegeneRx possesses one of three board seats of
ReGenTree  and  certain  major  decisions  and  transactions  within  ReGenTree,  such  as  commercialization  strategy,  mergers,  and  acquisitions,  require
RegeneRx’s board designee’s consent. We currently hold a 38.5% ownership interest in ReGenTree. This ownership interest may be further reduced to as low
as 25% once ReGenTree obtains FDA approval of an NDA for Dry Eye Syndrome in the U.S. In the event ReGenTree is acquired, or a change of control
occurs  following  achievement  of  an  NDA,  RegeneRx  shall  be  entitled  to  a  minimum  of  40%  of  all  proceeds  paid  or  payable  and  will  forgo  any  future
royalties.

To  date  ReGenTree  has  sponsored  a  Phase  2/3  clinical  trial  (“ARISE-1”)  and  Phase  3  clinical  trials  in  patients  with  dry  eye  syndrome  (“DES”)
(“ARISE-2”)  and  in  patients  with  neurotrophic  keratopathy  (“NK”)  (“SEER-1”),  all  in  the  U.S.  In  May  2016,  we  reported  the  results  of  the  317-patient
ARISE-1 trial and in October 2017, we reported the results of the ARISE-2 trial. The ARISE-2 study, which was sponsored by ReGenTree and managed by
Ora, Inc. pursuant a recent contract between the parties, demonstrated a number of statistically significant improvements in both signs and symptoms of dry
eye syndrome with 0.1% RGN-259 versus placebo, while showing excellent safety, comfort, and tolerability profiles. The ocular discomfort symptom showed
a statistically significant reduction in the RGN-259-treated group at day 15 as compared to placebo (p=0.0149) in the change from baseline. For sign, RGN-
259  also  improved  the  dry  eye  patient’s  ability  to  withstand  an  exacerbated  condition  in  a  patient  subgroup  with  both  compromised  corneal  fluorescein
staining and Schirmer’s test at baseline. In this population, RGN-259 showed superiority over placebo in reducing corneal fluorescein staining in the change
from baseline at days 15 and 29 (p=0.0207 and 0.0254, respectively). RGN-259 confirmed its global effects on dry eye syndrome and fast onset in multiple
sign and symptom efficacies with no safety issues in the ARISE-1 and ARISE-2 studies as well as in the pooled data, although ARISE-2 was not successful in
duplicating the results of ARISE-1 where the study population was limited and less diversified. ReGenTree is proceeding with its RGN-259 development plan
as discussed with the FDA in April 2018. Most recently, ReGenTree reaffirmed that the manufacturing of the investigational product for ARISE-3 has been
completed and the protocol for the study has been finalized. ReGenTree and Ora, Inc. have entered into a contract for management of ARISE-3. Ora, Inc.
recently initiated the study with the first patient anticipated to be enrolled in the second quarter of 2019.

The NK trial (SEER-1), a smaller study in an orphan population, has enrolled seventeen patients thus far, and has several additional patients being
screened,  with  a  goal  of  forty-six.  ReGenTree  has  expanded  its  efforts  to  accelerate  patient  enrollment  by  offering  incentives  to  each  study  site  based  on
numbers  of  enrollees  as  well  as  payments  to  referral  sites.  Earlier  in  2018,  ReGenTree  disclosed  that  7  of  17  patients  enrolled  SEER-1  have  completely
healed.  To  participate  in  the  trial  the  patients  were  required  to  have  a  persistent  epithelial  defect  (non-healing  corneal  wound).  While  these  preliminary
observations  are  encouraging,  it  should  be  noted  that  the  patients  and  treating  physicians  remain  masked  while  the  trial  is  on-going,  so  it  is  not  known
whether the healed patients are in the RGN-259 group, placebo group, or distributed among both. As of the date of this report, we do not know when this
study will be completed.

GtreeBNT has developed the CMC (chemistry, manufacturing and controls) dossier required for Phase 3 clinical trials and commercialization in the
U.S.  and  in  Korea.  This  comprehensive  and  critical  effort  ensures  that  final  drug  product  manufacturing,  packaging,  stability,  purity,  reproducibility,  etc.,
meets  regulatory  guidelines  and  product  specifications.  The  product  of  this  activity  is  the  current  product  format  being  utilized  in  the  U.S.  trials  being
conducted by ReGenTree and will also be utilized in the planned clinical activity to be conducted by GtreeBNT under the RGN-259 license agreement for
Pan Asia.

In February 2017, our licensee for RGN-137, GtreeBNT, received permission from the U.S. FDA to sponsor a Phase 3 clinical trial using RGN-137
to treat patients with epidermolysis bullosa (EB), a genetic disease that causes severe blistering of the skin and internal organs. In August 2017, the Company
amended  the  License  Agreement  for  RGN-137  held  by  GtreeBNT.  Under  the  amendment  the  Territory  was  expanded  to  include  Europe,  Canada,  South
Korea,  Australia  and  Japan.  GtreeBNT  initiated  a  small  open  trial  in  patients  with  EB  in  December  2018  to  evaluate  RGN-137  in  such  patients  prior  to
sponsoring a larger Phase 3 trial.

Currently,  we  have  active  partnerships  in  four  major  territories:  North  America,  Europe,  China  and  Pan  Asia.  Our  partners  have  been  moving
forward  and  making  progress  in  each  territory.  In  each  case,  the  cost  of  development  is  being  borne  by  our  partners  with  no  financial  obligation  for
RegeneRx. We still have significant clinical assets to develop, primarily RGN-352 (injectable formulation of Tß4 for cardiac and CNS disorders) in the U.S.,
most of Asia, and Europe; RGN-259 in the EU. In August 2017 we amended the RGN-137 License Agreement with GtreeBNT, expanding the territory to
include Europe, Canada, South Korea, Australia and Japan. Regarding RGN-259, our goal is to wait until satisfactory results are obtained from the current
ophthalmic clinical program in the U.S. before moving into the EU. This should allow us to obtain a higher value for the asset at that time. However, we
intend  to  continue  to  develop  RGN-352,  our  injectable  systemic  product  candidate  for  cardiac  and  central  nervous  system  indications,  either  by  obtaining
grants to fund a Phase 2a clinical trial in the cardiovascular or central nervous system fields or finding a suitable partner with the resources and capabilities to
develop it as we have with RGN-259.

We  anticipate  incurring  additional  operating  losses  in  the  future  as  we  continue  to  explore  the  potential  clinical  benefits  of  Tß4-based  product
candidates over multiple indications. To fund further development and clinical trials we have entered into a series of strategic partnerships under licensing and
joint venture agreements (see “Strategic Partnerships” below) where our partners are responsible for advancing development of our product candidates with
multiple clinical trials.

Overview of Tß4

Tß4 is a synthetic copy of a naturally occurring 43-amino acid peptide that was originally isolated from bovine thymus glands. It plays a vital role in

cell structure and motility and in the protection, regeneration, remodeling and healing of tissues.

Although it is recognized that wound healing and tissue regeneration are complex processes, most companies working to develop new drugs in this
area have focused primarily on the development of growth factors and genetic therapies to stimulate healing and have, to date, failed to demonstrate dramatic
improvements in the healing process. Numerous preclinical animal studies, published by independent researchers, have identified several important biological
activities involving Tß4 that we believe make it potentially useful as a wound healing, repair and tissue regenerating agent. These activities include:

·

·

·

·

Progenitor (Stem) Cell Recruitment and Differentiation.  Independent research published in the journal Nature in November 2006 featured the
discovery  that  Tß4  is  the  key  signaling  molecule  that  recruits  and  triggers  adult  epicardial  progenitor  cells,  or  EPCs,  to  differentiate  into
coronary  blood  vessels.  EPCs  are  partially  differentiated  stem  cells  that  can  further  differentiate  into  specific  cell  types  when  needed.
Confirmatory  research  published  in  2009  in  the  Journal  of  Molecular  and  Cellular  Cardiology  concluded  that  Tß4  is  responsible  for  the
initiation  of  the  embryonic  coronary  developmental  program  and  EPC  differentiation  in  adult  mice.  These  publications  confirm  that  Tß4’s
interaction  with  EPCs  is  necessary  for  the  maintenance  of  a  healthy  adult  animal  heart,  as  well  as  for  normal  embryo  and  fetal  heart
development  in  mammals.  In  Neuroscience  (2009  and  2010),  and  the  J.  Neurosurgery  (2010),  Tß4  was  shown  to  similarly  stimulate
oligodendrogenesis,  i.e.,  the  differentiation  of  oligodendroctye  progenitor  cells  into  myelin-producing  oligodendrocytes,  whereby  restoring
functional recovery in animal models of multiple sclerosis, stroke, and traumatic brain injury.

Actin Regulation.  Tß4 regulates actin, which comprises up to 10% of the protein of non-muscle cells in the body and plays a central role in cell
structure and in the movement of cells. Independent research studies have indicated that Tß4 stimulates the migration of human keratinocytes, or
skin cells, as well as corneal epithelial cells that protect the eye, human endothelial cells and progenitor cells of the heart and brain. Endothelial
cells  are  the  major  cell  type  responsible  for  the  formation  of  new  blood  vessels,  a  process  known  as  angiogenesis.  Certain  of  these  studies
conducted at the National Institutes of Health, or NIH, were the first to suggest the role of Tß4 in wound healing. The data from these studies
encouraged us to license the rights to Tß4 from the NIH in 2001 and to launch an initial clinical development program that targeted the use Tß4
for chronic dermal wounds.

Reduction of Inflammation and scar tissue formation.  Uncontrolled inflammation is the underlying basis of many pathologies and injuries.
Independent research has shown that Tß4 is a potent anti-inflammatory agent in skin cells and in corneal epithelial cells in the eye. Tß4 has also
been shown to decrease the levels of inflammatory mediators and to significantly reduce the influx of inflammatory cells in the reperfused heart
of animals. More recent preclinical research suggests that Tß4 blocks activation of the NFκB pathway, which is involved in DNA activation of
inflammatory mediators, thereby modulating inflammation in the body. This anti-inflammatory activity may explain, in part, the mechanism by
which Tß4 appeared to improve functional outcome in the mouse multiple sclerosis model described above, as well as promoting repair in the
heart and skin. In the skin, it has been shown to reduce scar formation by reduction of infiltration of myofibroblasts. Identifying a factor such as
Tß4  that  reduces  scarring  and  blocks  activation  of  NFκB  suggests  that  Tß4  could  have  additional  important  therapeutic  applications  for
inflammation-related  diseases,  such  as  cancer,  osteoarthritis,  rheumatic  diseases,  autoimmune  diseases,  inflammatory  pulmonary  disease  and
pancreatitis.

Collagen  and  Laminin-5  Stimulation.    Tß4  has  a  number  of  additional  biological  activities  shown  to  reduce  inflammation,  stimulate  the
formation of collagen, and up-regulate the expression of laminin-5, a subepithelial basement membrane protein. Both collagen and laminin-5 are
central to healthy tissue, wound repair and the prevention of disease. Laminin-5 promotes cell migration and maintains cell-cell and cell-matrix
contacts for intact tissues which are important for preventing fluid loss and bacterial infection.

5

 
 
 
 
 
 
 
 
 
 
·

Anti-Apoptosis.  Tß4 has  been  shown  to  prevent  apoptosis,  or  programmed  cell  death,  in  two  animal  models  and  in  two  tissue  types.  In  the
rodent  model,  corneal  apoptosis,  or  loss  of  corneal  epithelial  cells  leading  to  corneal  epithelial  thinning,  was  prevented  through  topical
administration of Tß4 eye drops. In the heart muscle of ischemic animal models, such as in mice and pigs, cell death was prevented by either
local or systemic administration of Tß4.

Tß4 has shown efficacy in heart repair and regeneration in numerous animal models. A 2004 paper in Nature showed that it could reduce the lesion
size,  improve  cardiac  function  and  promote  survival.  The  2006  Nature  publication  mentioned  above  further  concluded  that  Tß4’s  interaction  with  EPCs
resulted in the formation of cardiomyocytes that repaired damaged myocardium, or heart tissue, in mice after an induced acute myocardial infarction, or AMI,
commonly known as a heart attack. Research published in the journal Circulation showed Tß4’s cardioprotective effects in a pig ischemic-reperfusion model.
This pig model is accepted as an important model upon which to base human clinical research, as pigs are larger mammals, the anatomy of the pig heart is
similar to that of the human heart, and vascular response processes are completed five to six times faster in pigs than in humans, so that long-term results can
be obtained in a relatively short period of time. This research also identified Tß4’s interaction with EPCs as the underlying basis of cardioprotection through
the differentiation of EPCs into cardiomyocytes, yielding statistically significant cardiac functional recovery results when compared to the administration of
placebo.

Similar research in the area of brain and central nervous system tissues also showed efficacy of repair and regeneration was published in the journal
Neuroscience  in  2009.  This  publication  concluded  that  Tß4  triggered  the  differentiation  of  oligodendrocyte  progenitor  cells  to  form  myelin-producing
oligodendrocytes, which led to the remyelination of axons in the brain of mice with experimental autoimmune encephalomyelitis, or EAE. This mouse model
is an accepted small animal model for the study of multiple sclerosis. Research published in the Journal of Neurosurgery in 2010 and also in the Journal of
Neurological Science in 2014 showed that Tß4 could improve functional neurological outcome in an animal stroke model. A second study was published in
the Journal of Neurosurgery in 2011 demonstrating that administration of Tß4 can significantly improve histological and functional outcomes in rats with
traumatic brain injury, or TBI, indicating that Tß4 has considerable therapeutic potential for patients with TBI. More recently, researchers studying Tß4 under
a  material  transfer  agreement  (MTA)  found  that  Tß4  had  beneficial  effects  in  animal  models  of  peripheral  neuropathy,  one  of  the  major  complications  of
diabetes. This research was published in the Journal of Neurobiology of Disease in December 2012 and appears to corroborate previous findings using Tß4
for repair of central nervous system disorders. A paper in Neuropharmacology in 2014 found many benefits of Tß4 administration in a rat model of spinal
cord  injury,  including  decreased  lesion  size  at  7  days,  increased  neural  and  oligodendrocyte  survival,  increase  levels  of  myelin  basic  protein  (a  marker  of
mature oligodendrocytes), decreased ED1 (a marker of activated microglia/macrophages), and decreased proinflammatory cytokines. Thus, Tß4 has efficacy
for repair and regeneration in several nervous system injury models including MS, TBI, stroke, peripheral neuropathy, and spinal cord injury and there will
likely be additional applications in this area. We believe that these various biological activities work in concert to play a vital role in the healing and repair of
injured or damaged tissue and suggest that Tß4 is an essential component of the tissue protection and regeneration process that may lead to many potential
medical applications. All of our product candidates utilize Tß4 as the active pharmaceutical ingredient (API), which is manufactured by solid-phase peptide
synthesis and is an exact copy of the naturally occurring peptide. We have created three distinct formulations for various routes of administration and medical
indications.

Our Product Candidates

RGN-259

RGN-259 is our proprietary preservative-free eye drop formulation of Thymosin beta 4. In September 2011, we completed a Phase 2a exploratory
clinical  trial  evaluating  the  safety  and  efficacy  of  RGN-259  in  72  patients  with  moderate  dry  eye  syndrome.  In  November  2011,  we  reported  preliminary
safety and efficacy results from the trial. RGN-259 was deemed safe and well-tolerated, with no observed drug-related adverse events.

In June 2012, we reported preliminary results from a double-masked, vehicle-controlled, physician-sponsored Phase 2 clinical trial evaluating RGN-
259 for the treatment of nine patients (18 eyes) with severe dry eye. RGN-259 was observed to be safe and well-tolerated and met key efficacy objectives
with statistically significant sign and symptom improvements, compared to vehicle control, at various time intervals, including 28 days post-treatment.

Consistent with the reduction of ocular discomfort and fluorescein staining at the 28-day follow-up visit, other improvements seen in the RGN-259-
treated patients included tear film breakup time and increased tear volume production. Likewise, these improvements were seen at other time points in the
study. These results were published in Cornea in 2015.

In September 2015, ReGenTree began the Phase 2/3 ARISE-1 clinical trial in patients with dry eye syndrome (and the Phase 3 SEER-1 clinical trial
in patients with neurotrophic keratopathy (“NK”), both in the U.S. In May 2016, we reported the results of the 317-patient ARISE-1 dry eye trial. In the trial,
RGN-259 demonstrated statistically significant improvements in both signs and symptoms of dry eye with 0.05% and 0.1% RGN-259 compared to placebo in
a dose dependent manner during a 28-day dosing period. While the primary outcome measures were not met, several key related pre-specified endpoints and
subgroups  of  patients  with  more  severe  dry  eye  showed  statistically  significant  treatment  effects.  These  results  confirmed  the  findings  from  the  previous
Phase 2 trial providing clear direction for the clinical regulatory pathway and remaining registration trials for RGN-259. Shortly following the ARISE-1 trial,
the FDA approved ReGenTree’s Phase 3 ARISE-2 dry eye protocol and we initiated the ARISE-2 trial that enrolled approximately 600 patients.

The ARISE-2 study, which was sponsored by ReGenTree and managed by Ora, Inc., demonstrated a number of statistically significant improvements
in both signs and symptoms of dry eye syndrome with 0.1% RGN-259 versus placebo, while showing excellent safety, comfort, and tolerability profiles. The
ocular discomfort symptom showed a statistically significant reduction in the RGN-259-treated group at day 15 as compared to placebo (p=0.0149) in the
change from baseline. For sign, RGN-259 also improved the dry eye patient’s ability to withstand an exacerbated condition in a patient subgroup with both
compromised corneal fluorescein staining and Schirmer’s test at baseline. In this population, RGN-259 showed superiority over placebo in reducing corneal
fluorescein staining in the change from baseline at days 15 and 29 (p=0.0207 and 0.0254, respectively). RGN-259 confirmed its global effects on dry eye
syndrome and fast onset in multiple sign and symptom efficacies with no safety issues in the ARISE-1 and ARISE-2 studies as well as in the pooled data,
although ARISE-2 was not successful in duplicating the results of ARISE-1 where the study population was limited and less diversified.

In February 2019 ReGenTree initiated a 700-patient ARISE-3 trial in patients with dry eye syndrome to confirm the results observed in ARISE-2.

We anticipate the first patient will be enrolled in the second quarter of 2019.

Strategic Partnerships

Lee’s Pharmaceuticals. We are a party to a license agreement with Lee’s Pharmaceutical for the license of Thymosin Beta 4 in any pharmaceutical
form,  including  our  RGN-259,  RGN-352  and  RGN-137  product  candidates,  in  China,  Hong  Kong,  Macau  and  Taiwan.  In  February  2019,  the  License
Agreement was assigned by Lee’s to their affiliate, Zhaoke Ophthalmology Pharmaceutical Limited. Lee’s previously filed an IND with the Chinese FDA to
conduct a Phase 2, randomized, double-masked, dose-response clinical trial with RGN-259 in China for dry-eye syndrome. Lee's subsequently informed us
that it received notice from China's FDA declining its IND application for a Phase 2b dry eye clinical trial because the API was manufactured outside of
China. The API was manufactured in the U.S. and provided to Lee's by RegeneRx pursuant to a license agreement to develop RGN-259 ophthalmic eye drops
in  the  licensed  territory.  However,  in  mid-2016,  we  were  informed  by  Lee’s  that  the  CFDA  modified  its  manufacturing  regulations  and  will  now  allow
Chinese companies to utilize API manufactured outside of China for Phase 1 and 2 clinical trials. We have not yet been informed of a projected starting date
for Phase 2 trials.

GtreeBNT. We are a party to a license agreement with GtreeBNT for the license of RGN-259 related to certain development and commercialization
rights  for  RGN-259,  in  Asia  (excluding  China,  Hong  Kong,  Macau  and  Taiwan).  Separately,  we  licensed  GtreeBNT  the  rights  to  RGN-137  which  was
recently amended as discussed above. GtreeBNT is currently our second largest stockholder. GtreeBNT filed an IND with the Korean Ministry of Food and
Drug Safety to conduct a Phase 2/3 study with RGN-259 in patients with dry eye syndrome and in July 2015 received approval to conduct the trial. In late
2016 GtreeBNT informed us that it believes marketing approval in the U.S. will allow expedited marketing in Korea, possibly without the need for a clinical
trial. At this point, we are still awaiting marketing approval in the U.S.

U.S. Joint Venture (ReGenTree, LLC).

We are a party to a Joint Venture Agreement with GtreeBNT and a License Agreement with ReGenTree for the commercialization of RGN-259 for

treatment of dry eye and neurotrophic keratopathy in the United States, as well as any other relevant ophthalmic indications.

In September 2015, ReGenTree began the Phase 2/3 ARISE-1 clinical trial in patients with dry eye syndrome (and the Phase 3 SEER-1 clinical trial
in patients with neurotrophic keratopathy (“NK”), both in the U.S. In May 2016, we reported the results of the 317-patient ARISE-1 dry eye trial. In the trial,
RGN-259 demonstrated statistically significant improvements in both signs and symptoms of dry eye with 0.05% and 0.1% RGN-259 compared to placebo in

finalized. Ora, Inc. recently initiated the study with the first patient anticipated to be enrolled in the second quarter of 2019.

RGN-352

During  2009,  we  completed  a  Phase  1a  and  Phase  1b  clinical  trial  evaluating  the  safety,  tolerability  and  pharmacokinetics  of  the  intravenous
administration of RGN-352 in 60 healthy subjects (40 in each group, 20 of whom participated in both Phases). Based on the results of these Phase 1 trials and
extensive preclinical efficacy data published in peer-reviewed journals, in the second half of 2010, we began start-up activities for a Phase 2 study to evaluate
RGN-352 (Tß4 Injectable Solution) in patients who had suffered an AMI. We had planned to begin enrolling patients in this clinical trial in the second quarter
of 2011. However, in March 2011, we were notified by the FDA that the trial was placed on clinical hold as a result of our contract manufacturer’s alleged
failure to comply with the current Good Manufacturing Practice (cGMP) regulations. The manufacturer has since closed its manufacturing facility and filed
for  bankruptcy  protection.  The  FDA  prohibited  us  from  using  any  of  the  active  drug  or  placebo  formulated  by  this  manufacturer  in  human  trials;
consequently, we must have study drug (RGN-352 and RGN-352 placebo) manufactured by a new cGMP-compliant manufacturer in the event we seek to
move forward with this trial. While we have identified a qualified manufacturer for RGN-352, we elected to postpone activities on this trial until the requisite
funding or a partner is secured.

In  addition  to  the  potential  application  of  RGN-352  for  the  treatment  of  cardiovascular  disease,  preclinical  research  published  in  the  scientific
journals Neuroscience and the Journal of Neurosurgery, among others, indicates that RGN-352 may also prove useful for patients with multiple sclerosis, or
MS, as well as patients suffering a stroke, traumatic brain injury, peripheral neuropathy, or spinal cord injury. In these preclinical studies, the administration of
Tß4  resulted  in  regeneration  of  neuronal  tissue  by  promoting  remyelination  of  axons  and  stimulating  oligodendrogenesis,  resulting  in  improvement  of
neurological functional activity. In 2012, researchers studying Tß4 under a material transfer agreement (MTA) found that Tß4 had beneficial effects in animal
models of peripheral neuropathy, one of the major complications of diabetes. This research was published in the journal of Neurobiology of Disease in 2012
and appears to corroborate previous findings using Tß4 for repair of central nervous system disorders. We are discussing possible partnership opportunities
with companies interested in developing RGN-352 for cardiac and central nervous system indications and are working with an Asian-based medical center
seeking grant funding for cardiovascular studies.

Based on our Phase 1 data and the preclinical research discussed above, we are evaluating various opportunities for government funding for a Phase
2a clinical trial to show proof-of-concept in each case while also talking with prospective strategic partners with the interest, capabilities and resources to
further develop product candidate in these fields.

RGN-137

Clinical Development — Epidermolysis Bullosa (EB).  Starting in 2005, we began conducting a Phase 2 clinical trial designed to assess the safety
and effectiveness of RGN-137 for the treatment of patients with EB. EB is a genetic disease of approximately 10 gene mutations that results in fragile skin
and other epithelial structures (e.g., cornea and GI tract) that can blister spontaneously or separate at the slightest trauma or friction, creating a wound that at
times  does  not  heal  or  heals  poorly.  In  severe  cases,  recurrent  blistering  and  tissue  loss  may  be  life  threatening.  EB  has  been  designated  as  an  “orphan”
indication by the FDA’s Office of Orphan Drugs. We closed the Phase 2 trial in late 2011 and we submitted the final report to the FDA in 2014. In February
2017, GtreeBNT received permission from the U.S. FDA to sponsor a Phase 3 clinical trial using RGN-137 to treat patients with EB. In December 2018,
GtreeBNT initiated a small open trial in a limited number of patients with EB.

Clinical Development — Pressure Ulcers.  In late 2005, we began conducting Phase 2 clinical trial designed to assess the safety and effectiveness of

RGN-137 for the treatment of patients with chronic pressure ulcers, commonly known as bedsores.

8

 
 
 
 
 
 
 
 
 
 
In January 2009, we reported final data from this trial. RGN-137 was well-tolerated at all three dose levels studied, with no dose-limiting adverse
events, which achieved the primary objective of the study. A follow-on evaluation, reported at the 3rd International Symposium on the Thymosins in Health
and  Disease  in  March  2012,  showed  that  for  those  pressure  ulcer  patients’  wounds  that  healed,  RGN-137  mid  dose  (0.02%  Tβ4  gel  product)  accelerated
wound closure with a median time to healing of 22 days as compared to 57 days for the placebo. Although those results are clinically significant, they were
not statistically significant.

Clinical  Development  —  Venous  Stasis  Ulcers.  In  mid-2006  we  began  conducting  a  Phase  2  clinical  trial  designed  to  assess  the  safety  and
effectiveness of RGN-137 for the treatment of patients with venous stasis ulcers. Venous stasis ulcers are a common type of chronic wound that develops on
the  ankle  or  lower  leg  in  patients  with  chronic  vascular  disease.  In  these  patients’  blood  flow  in  the  lower  extremities  is  impaired  leading  to  venous
hypertension, edema (swelling) and mild redness and scaling of the skin that gradually progresses to ulceration. In 2009, we reported final data from that trial.
Those results were both clinically and statistically significant.

Our Strategy

We seek to maximize the value of our product candidates by advancing their clinical development and then identifying suitable partners for further
development,  regulatory  approval,  and  marketing.  We  intend  to  engage  in  strategic  partnerships  with  companies  with  clinical  development  and
commercialization strengths in desired pharmaceutical therapeutic fields. We are actively seeking partners with suitable infrastructure, expertise and a long-
term initiative in our medical fields of interest. To that end, we have entered the licensing and joint ventures discussed above.

In 2004, we entered into a strategic partnership for development and marketing of RGN-137 and RGN-352 for specified fields of use in Europe and
other  contiguous  countries  with  Sigma-Tau  Group,  which  was  subsequently  acquired  by  Alfa  Wassermann  S.p.A.,  both  Italian  pharmaceutical  companies.
Pursuant to the terms of the license, we notified Alfa Wassermann that the license expired by its terms and we, therefore, reacquired rights to our Tß4-based
products in the licensed territory. In August 2017, the Company amended the License Agreement for RGN-137 held by GtreeBNT. Under the amendment the
Territory was expanded to include Europe, Canada, South Korea, Australia and Japan. Further, we now control the cardiovascular and neurovascular assets
(RGN-352) in the EU and are able to consolidate them with similar assets in the U.S. and other territories in Asia to create a worldwide portfolio that we
believe will be more attractive to multi-national pharmaceutical companies.

Manufacturing

We use a major contract manufacturer to produce bulk Tß4, which is the active pharmaceutical ingredient, or API, in our product candidates by an
established and proven manufacturing process known as solid-phase peptide synthesis. While we do not currently have long-term supply agreements in place,
we and ReGenTree intend to establish a long-term supply arrangement with at least one manufacturer once practicable. No assurance can be given, however,
that  such  agreements  will  be  negotiated  on  favorable  terms,  or  at  all.  Contractors  are  selected  on  the  basis  of  their  supply  capability,  ability  to  produce  a
product in accordance with Current Good Manufacturing Practice, or cGMP, requirements of the FDA and ability to meet our established specifications and
quality  requirements.  Given  our  recent  licensing  and  joint  venture  deals,  our  partner  in  Korea  and  the  U.S.  are  working  closely  with  our  current  primary
contract manufacturer on the cGMP validation process and consistency runs, among other things, to prepare for the manufacture of bulk Tß4 for use in future
clinical trials and commercialization of our formulated product candidates. Through ReGenTree we are also identifying and qualifying other potential API
manufacturers. RegeneRx will have access to the data resulting from this endeavor should we need to use it for purposes outside the licensed territories.

We also use a number of outside contract manufacturers to formulate bulk Tß4 into our product candidates, RGN-137, RGN-259 and RGN-352. We
use separate manufacturers for each formulation of Tß4. All of these formulations may require modifications, along with additional studies, as we advance
our clinical development programs through commercialization.

Competition

We are engaged in a business that is highly competitive, and our target medical indications are ones with significant unmet needs. Consequently,
there are many enterprises, both domestic and foreign, pursuing therapies and products that could compete with ours. Most of these entities have financial and
human resources that are substantially greater than ours, specifically with regard to the conduct of clinical research and development activities, clinical testing
and in obtaining the regulatory approvals necessary to market pharmaceutical products. Brief descriptions of some of these competitive products follow:

RGN-259.  Most specialty ophthalmic companies have a number of products on the market that could compete with RGN-259. There are numerous
antibiotics to treat eye infections to promote corneal wound healing and many eye lubrication products that are soothing to the eye and help eye healing, many
of  which  are  sold  without  prescriptions.  Companies  also  market  steroids  to  treat  certain  conditions  within  our  area  of  interest.  Allergan,  Inc.  markets
Restasis™, Ophthalmic Emulsion, an FDA-approved eye drop used to treat dry eye. Restasis, and other products, have been approved for marketing in certain
other countries where we have licensed RGN-259. Shire PLC is marketing its recently FDA-approved product, Xiidra. We believe RGN-259 is different from
Restasis and Xiidra and any other product or product candidate available for dry eye in that it actively promotes repair using a multi-faceted approach of
increasing cell migration and laminin-5 production, and decreasing inflammation and apoptosis, without any noted adverse effects.

RGN-352.  Currently, we do not believe there are any approved pharmaceutical products for regenerating cardiac tissue following a heart attack, nor
for  regeneration  of  nervous  tissue  or  for  the  remyelination  of  axons  of  patients  with  multiple  sclerosis  or  patients  suffering  from  traumatic  brain  injury.
However, many pharmaceutical companies and research organizations are developing products, pharmacologic and stem cell therapies and technologies that
are intended to prevent cardiac damage, improve cardiac function, and regenerate cardiac muscle after a heart attack. There are also companies developing
products that are purported to remyelinate neurons and provide functional improvement for patients suffering from multiple sclerosis, stroke, traumatic brain
injury, and peripheral neuropathy. If we, or a partner, were to successfully develop RGN-352 for cardiovascular or central nervous system indications, such
products  would  have  to  compete  with  other  drugs  or  therapies  currently  being  developed  or  marketed  by  large  pharmaceutical  companies  for  similar
indications.

RGN-137.      There  are  numerous  companies  developing  new  pharmaceutical  products  for  wound  healing  and  for  EB,  in  particular.  Products  and
therapies such as antibiotics, honey-based ointments, silver-based compounds and low frequency cavitational ultrasound are also used to treat certain types of
dermal  wounds.  Moreover,  dermal  wound  healing  is  a  large  and  highly  fragmented  marketplace  that  includes  numerous  therapeutic  products  and  medical
devices for treating acute and chronic dermal wounds. Most recently, various other companies are attempting to develop genetic therapies to try to heal or
prevent serious wound disorders.

 Government Regulation

In  the  United  States,  the  Federal  Food,  Drug,  and  Cosmetic  Act,  as  amended,  or  FFDCA,  and  the  regulations  promulgated  thereunder,  and  other
federal and state statutes and regulations govern, among other things, the testing, manufacturing, labeling, storing, recordkeeping, distribution, advertising and
promotion  of  our  product  candidates.  Regulation  by  governmental  authorities  in  the  United  States  and  foreign  countries  will  be  a  significant  factor  in  the
manufacturing and potential marketing of our product candidates and in our ongoing research and product development activities. Any product candidate we
develop  will  require  regulatory  approval  by  governmental  agencies  prior  to  commercialization.  In  particular,  human  therapeutic  products  are  subject  to
rigorous  preclinical  studies,  clinical  trials  and  other  approval  procedures  by  the  FDA  and  similar  health  authorities  in  foreign  countries.  The  process  of
obtaining  these  approvals  and  subsequent  compliance  with  appropriate  federal  and  state  statutes  and  regulations  requires  the  expenditure  of  substantial
resources.

Preclinical  studies  must  ordinarily  be  conducted  to  evaluate  an  investigational  new  drug’s  potential  safety  by  toxicology  studies  and  potential
efficacy  by  pharmacology  studies.  The  results  of  these  studies,  among  other  things,  are  submitted  to  the  FDA  as  part  of  an  Investigational  New  Drug
Application, or IND, which must be reviewed by the FDA before clinical trials can begin. Typically, clinical evaluation involves a three-stage process. Phase
1  clinical  trials  are  conducted  with  a  small  number  of  healthy  volunteers  to  determine  the  safety  profile  and  the  pattern  of  drug  absorption,  distribution,
metabolism and excretion, and to assess the drug’s effect on the patient. Phase 2, or therapeutic exploratory, trials are conducted with somewhat larger groups
of  patients,  who  are  selected  by  relatively  narrow  criteria  yielding  a  more  homogenous  population  that  is  afflicted  with  the  target  disease,  in  order  to
determine preliminary efficacy, optimal dosages and expanded evidence of safety. Phase 2 trials should allow for the determination of the dose to be used in
Phase 3 clinical trials. Phase 3, or therapeutic confirmatory, large scale, multi-center, comparative trials are conducted with patients afflicted with a target
disease  in  order  to  provide  enough  data  for  the  statistical  proof  of  safety  and  efficacy  required  by  the  FDA  and  other  regulatory  authorities.  The  primary
objective of Phase 3 clinical trials is to show that the drug confers therapeutic benefit that outweighs any safety risks. All clinical trials must be registered
with a central public database, such as www.clinicaltrials.gov, and once completed, results of the clinical trials must be entered in the database.

The results of these preclinical studies and clinical trials, along with detailed information on manufacturing, are submitted to the FDA in the form of
a New Drug Application, or NDA, for approval to commence commercial sales. The FDA’s review of an NDA requires the payment of a user fee currently in
excess of $1.8 million, which may be waived for the first NDA submitted by a qualifying small business. In responding to an NDA, the FDA may refuse to
file  the  application  if  the  FDA  determines  that  the  application  does  not  satisfy  its  regulatory  approval  criteria,  request  additional  information  or  grant
marketing  approval.  Therefore,  even  if  we  complete  Phase  3  clinical  trials  for  our  product  candidates  and  submit  an  NDA  to  the  FDA,  there  can  be  no
assurance that the FDA will grant marketing approval, or if granted, that it will be granted on a timely basis. If the FDA does approve a product candidate, it
may require, among other things, post-marketing testing, including potentially expensive Phase 4 trials, which monitor the safety of the drug. In addition, the
FDA may in some circumstances impose risk evaluation and mitigation strategies that may be difficult and expensive to administer. Product approvals may be
withdrawn if compliance with regulatory requirements is not maintained or if problems occur after the product reaches the market.

10

 
 
 
 
 
 
 
 
Among  the  conditions  for  NDA  approval  is  the  requirement  that  the  applicable  clinical,  pharmacovigilance,  quality  control  and  manufacturing
procedures  conform  on  an  ongoing  basis  with  current  Good  Clinical  Practices,  Good  Laboratory  Practices,  current  Good  Manufacturing  Practices,  and
computer information system validation standards. During the review of an NDA, the FDA will perform a pre-licensing inspection of select clinical sites,
manufacturing  facilities  and  the  related  quality  control  records  to  determine  the  applicant’s  compliance  with  these  requirements.  To  assure  compliance,
applicants  must  continue  to  expend  time,  money  and  effort  in  the  area  of  training,  production  and  quality  control.  After  approval  of  any  product,
manufacturers  are  subject  to  periodic  inspections  by  the  FDA.  If  a  company  fails  to  comply  with  FDA  regulatory  requirements,  FDA  may  pursue  a  wide
range of remedial actions, including seizure of products, corrective actions, warning letters and fines.

We  have  received  orphan  drug  designation  from  the  FDA  for  RGN-137  for  the  treatment  of  EB  and  RGN-259  for  the  treatment  of  neurotrophic
keratopathy or NK, (now to be developed by ReGenTree). The FDA may designate a product or products as having orphan drug status to treat a disease or
condition that affects less than 200,000 individuals in the United States, or, if patients of a disease number more than 200,000, the sponsor can establish that it
does not realistically anticipate its product sales will be sufficient to recover its costs. If a product candidate is designated as an orphan drug, then the sponsor
may receive incentives to undertake the development and marketing of the product, including grants for clinical trials, as well as a waiver of the user fees for
submission of an NDA application. For example, as described above, we received a grant from the FDA for our Phase 2 clinical trial of RGN-137 to treat
patients with EB.

Generally, if a product with an orphan drug designation subsequently receives the first marketing approval for the indication for which it has such
designation, the product is entitled to marketing exclusivity for a period of seven years in the United States and ten years in the EU. There may be multiple
designations of orphan drug status for a given drug and for different indications. Orphan drug designation does not guarantee that a product candidate will be
approved by the FDA for marketing for the designation, and even if a sponsor of a product candidate for an indication for use with an orphan drug designation
is the first to obtain FDA approval of an NDA for that designation and obtains marketing exclusivity, another sponsor’s application for the same drug product
may be approved by the FDA during the period of exclusivity if the FDA concludes that the competing product is clinically superior. In this instance, the
orphan designation and marketing exclusivity originally granted would be lost in favor of the clinically superior product.

Intellectual Property

We  hold  worldwide  patents  and  patent  applications  covering  peptide  compositions,  uses  and  formulations  related  to  dermal  and  ophthalmic
indications and other organ and tissue repair activities. In 2001, we entered into a license agreement with the NIH under which we received an exclusive
worldwide license from the NIH for all claims within the scope of the NIH’s patent application, and any issued patents, covering the use of Tß4 as a tissue
repair  and  regeneration  factor.  In  2007,  patents  were  issued  in  Europe  and  the  United  States  related  to  the  original  NIH  patent  application.  These  patents
expire  in  July  2019.  Corresponding  patents  have  also  been  granted  in  Hong  Kong,  Australia  and  China  and  certain  other  territories.  The  issued  European
patent was opposed by a third party at the European Patent Office and, in December 2009, we argued the case before the Opposition Division of the European
Patent Office in Munich, Germany and prevailed with certain amendments to the claims. In exchange for the exclusive license, we agreed to make certain
minimum royalty and milestone payments to the NIH.

We hold a U.S. patent relating to the use of Tß4 for the treatment of congestive heart failure. This patent was issued in January 2012. In 2006, we
were issued a patent in China for the use of Tß4 to treat EB. We also hold two patents for the treatment of dry eye in the U.S. and a patent for certain neuro
disorders, as well as peripheral neuropathy. Other patent applications for our various product candidates, if issued, will offer protection in the U.S. and certain
other territories through 2033.

We,  and  our  partners,  have  also  filed  additional  U.S.  and  international  patent  applications  covering  various  compositions,  uses,  formulations  and
other  components  of  Tß4,  as  well  as  for  novel  peptides  resulting  from  our  research  efforts,  the  latest  of  which  were  filed  during  2015.  There  can  be  no
assurance that these, or any other future patent applications under which we have rights, will result in the issuance of a patent or that any patent issued will
not be subject to challenge or opposition. In the case of a claim of patent infringement by or against us, there can be no assurance that we will be able to
afford the expense of any litigation that may be necessary to enforce our proprietary rights or that relevant patents will not expire prior to approval of any of
our product candidates.

We continuously evaluate our patents and patent applications in certain territories to determine whether it is cost-effective to continue to maintain or
prosecute them. In some cases, we have determined that the value or potential value of such patents and/or applications is not worth the continued effort or
expense and have either ceased efforts to pursue specific patents or abandoned any that have short expiries or cover countries of minimal strategic interest to
us or our partners. We will continue to evaluate our portfolio and take such actions from time to time as appropriate.

Material Agreements

National Institutes of Health

We are party to a license agreement with NIH under which we are obligated to pay an annual minimum royalty of $2,000. In 2013, we amended
certain provisions of the exclusive license; we were permitted to credit amounts paid to prosecute or maintain the licensed patent rights during 2013 calendar
year against the 2013 minimum annual royalty. Beginning in 2014, the minimum annual royalty is $2,000. Additionally, we are obligated to pay the NIH a
percentage of sales of qualifying product candidates, if any. There have been no such sales to date. Through December 31, 2018, we have complied with all
minimum royalty requirements, and no milestone payments have been required under the agreement. The patent is due to expire in 2019.

Lee’s Pharmaceuticals

On  July  15,  2012,  we  entered  into  a  License  Agreement  with  Lee’s  Pharmaceutical  for  the  license  of  Tß4  in  any  pharmaceutical  formulation,
including our RGN-259, RGN-352 and RGN-137 product candidates, in China, Hong Kong, Macau and Taiwan. The terms of the License Agreement include
aggregate potential milestone payments of up to $3.6 million and royalties ranging from low double digit to high single digit royalties on commercial sales, if
any. Under the License Agreement, Lee’s is responsible for all developmental costs associated with each product candidate. We provided Tß4 to Lee’s at no
charge for a Phase 2 ophthalmic clinical trial and will provide Tß4 to Lee’s for all other developmental and clinical work at a price equal to our cost.

The  Company  has  discussed  Lee’s  development  plans  and  we  have  continued  to  provide  information  as  requested.  Lee’s  previously  filed  an
investigational new drug application IND with the Chinese FDA to conduct a Phase 2, randomized, double-masked, dose-response clinical trial with RGN-
259 in China for dry-eye syndrome. Lee’s subsequently informed us that it received notice from China's FDA (CFDA) declining its investigational new drug
(IND) application for a Phase 2b dry eye clinical trial because the API (active pharmaceutical ingredient or Tß4) was manufactured outside of China. The API
was manufactured in the U.S. and provided to Lee's by RegeneRx pursuant to a license agreement to develop RGN-259 ophthalmic eye drops in the licensed
territory. However, in mid-2016, we were informed by Lee’s that the CFDA modified its manufacturing regulations and will now allow Chinese companies to
utilize API manufactured outside of China for Phase 1 and 2 clinical trials. We have not yet been informed of a projected starting date for Phase 2 trials. In
February 2019, the License Agreement was amended and assigned by Lee’s to their affiliate, Zhaoke Ophthalmology Pharmaceutical Limited. There are no
economic changes to the License Agreement.

GtreeBNT

On  March  7,  2014,  we  entered  into  license  agreements  with  GtreeBNT  Co.,  Ltd.  The  two  Licensing  Agreements  are  for  the  license  of  territorial

rights to two of our Thymosin Beta 4-based products candidates, RGN-259 and RGN-137.

Under  the  License  Agreement  for  RGN-259,  our  preservative-free  eye  drop  product  candidate,  GtreeBNT  will  have  the  right  to  develop  and
commercialize RGN-259 in Asia (excluding China, Hong Kong, Taiwan, and Macau). The rights will be exclusive in Korea, Japan, Australia, New Zealand,
Brunei, Cambodia, East Timor, Indonesia, Laos, Malaysia, Mongolia, Myanmar (Burma), Philippines, Singapore, Thailand, Vietnam, and Kazakhstan, and
semi-exclusive in India, Pakistan, Bangladesh, Bhutan, Maldives, Nepal, Sri Lanka, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan, collectively, the
Territory (the “259 Territory”). Under the License Agreement for RGN-259 we are eligible to receive aggregate potential milestone payments of up to $3.5
million. In addition, we are eligible to receive royalties of a low double-digit percentage of any commercial sales of the licensed product sold by GtreeBNT in
the 259 Territory.

Under  the  License  Agreement  for  RGN-137,  our  topical  dermal  gel  product  candidate,  GtreeBNT  will  have  the  exclusive  right  to  develop  and
commercialize  RGN-137  in  the  U.S.  (the  “137  Territory”).  Under  the  License  Agreement  for  RGN-137  we  are  eligible  to  receive  aggregate  potential
milestone payments of up to $3.5 million. In addition, we are eligible to receive royalties of a low double-digit percentage of any commercial sales of our
licensed product sold by GtreeBNT in the 137 Territory. Under an amendment to the License Agreement for RGN-137, for which we were compensated, the
137 Territory was expanded to include Europe, Canada, South Korea, Australia and Japan.

Both the License Agreement for RGN-137 and the License Agreement for RGN-259 contain diligence provisions that require the initiation of certain
clinical  trials  within  certain  time  periods  that,  if  not  met,  would  result  in  the  loss  of  rights  or  exclusivity  in  certain  countries.  GtreeBNT  will  pay  for  all
developmental costs associated with each product candidate. We retain the manufacturing and supply rights for Tß4 in the 259 Territory and 137 Territory and
the parties will negotiate in good faith an exclusive supply agreement for Tß4 as soon as practicable. We will also have the right to exclusively license any
improvements made by GtreeBNT to our products outside of the licensed territory on a royalty-free basis.

The  two  firms  have  created  a  joint  development  committee  and  continue  to  discuss  and  the  development  of  the  licensed  products  and  share
information relating thereto. Both companies will also share all non-clinical and clinical data and other information related to development of the licensed
product candidates.

ReGenTree - U.S. Joint Venture

On January 28, 2015, we entered into the Joint Venture Agreement with GtreeBNT, a shareholder in the Company and licensee in certain Pan Asian
countries. The Joint Venture Agreement provides for the creation of the Joint Venture, ReGenTree, LLC (“ReGenTree”), jointly owned by the Company and
GtreeBNT  that  will  commercialize  RGN-259  for  treatment  of  dry  eye  and  neurotrophic  keratopathy  in  the  United  States,  as  well  as  any  other  relevant
ophthalmic indications.

GtreeBNT is solely responsible for funding all of the product development and commercialization efforts of ReGenTree. GtreeBNT made an initial
contribution of $3 million in cash and received an initial equity stake of 51%. RegeneRx received and initial equity stake of 49% of ReGenTree. GtreeBNT’s
equity stake may increase (and RegeneRx’s would proportionally decrease) upon ReGenTree achieving certain product development milestones (including
receipt of a new drug application (“NDA”) by the U.S. FDA). GtreeBNT has subsequently funded the initial Phase 2b/3 and the ongoing Phase 3 U.S. clinical
trials for dry eye syndrome and neurotrophic keratopathy, respectively.

Our initial ownership interest in ReGenTree was 49% and was reduced to 38.5% after filing of the final clinical study report with the FDA for the
Phase 3 trial for Dry Eye Syndrome completed in 2017. Based on when, and if, ReGenTree achieves certain additional development milestones in the U.S.
with  RGN-259,  our  equity  ownership  may  be  incrementally  reduced  to  between  38.5%  and  25%,  with  25%  being  the  final  equity  ownership  upon  FDA
approval of an NDA for Dry Eye Syndrome in the U.S. In addition to our equity ownership, RegeneRx retains a royalty on net sales that varies between single
and low double digits, depending on whether commercial sales are made by ReGenTree or a licensee. In the event the ReGenTree entity is acquired or there is
a change of control that occurs following achievement of an NDA, RegeneRx shall be entitled to a minimum of 40% of all proceeds paid or payable and will
forgo any future royalties.

The Company is not required or otherwise obligated to provide financial support to ReGenTree.

ReGenTree  is  responsible  for  executing  all  development  and  commercialization  activities  under  the  License  Agreement,  which  activities  will  be
directed by a joint development committee comprised of representatives of the Company and GtreeBNT. The License Agreement has a term that extends to
the later of the expiration of the last patent covered by the License Agreement or 25 years from the first commercial sale under the License Agreement. The
License Agreement may be earlier terminated if the Joint Venture fails to meet certain commercialization milestones, or if either party breaches the License
Agreement and fails to cure such breach, or as a result of government action that limits the ability of the Joint Venture to commercialize the product, as a
result  of  a  challenge  to  a  licensed  patent,  following  termination  of  the  license  between  the  Company  and  certain  agencies  of  the  United  States  federal
government, or upon the bankruptcy of either party.

Development Agreements

While we are not currently directly engaged in development activities, historically we have entered into agreements with outside service providers
for the manufacture and development of Tß4, the formulation of Tß4 into our product candidates, the conduct of nonclinical safety, toxicology and efficacy
studies in animal models, and the management and execution of clinical trials in humans. Terms of these agreements vary in that they can last from a few
months  to  more  than  a  year  in  duration.  For  additional  information  regarding  our  research  and  development  expenses  over  the  past  two  years,  see
“Management’s Discussion and Analysis of Financial Condition and Results of Operations — Results of Operations” in this report.

Item 1A.  Risk Factors

Set forth below and elsewhere in this report and in other documents we file with the SEC are risks and uncertainties that could cause actual results to
differ  materially  from  the  results  contemplated  by  the  forward-looking  statements  contained  in  this  report.  The  descriptions  below  include  any  material
changes  to  and  supersede  the  description  of  the  risk  factors  affecting  our  business  previously  disclosed  in  “Part  II,  Item  1A.  Risk  Factors”  of  the  Annual
Report.

Risks Related to Our Liquidity and Need for Financing

Before giving effect to any potential additional sales of our securities, we estimate that our existing capital resources coupled with the proceeds from the
February 2019 note sales will only be sufficient to fund our operations through the first quarter of 2020.

Even though we sold a series of convertible promissory notes in February 2019 and will receive proceeds of $1,300,000, these proceeds are only
projected to fund our operations at the current level through the first quarter of 2020, therefore we will need to secure additional operating capital to continue
operations  beyond  the  first  quarter  of  2020.  We  continuously  monitor  our  cash  use  as  well  as  the  clinical  timelines.  We  will  need  to  secure  additional
operating capital in 2019 or early 2020 and are evaluating options including the licensing of additional rights to commercialize our clinical products as well as
raising capital through the capital markets which may cause a reduction in the trading price of our common stock.

We  will  need  substantial  additional  capital  for  the  continued  development  of  product  candidates  through  marketing  approval  and  for  our  longer-term
future operations.

We anticipate that substantial new capital resources will be required to continue our longer-term product development efforts, including any and all
follow-on  trials  that  will  result  from  our  current  clinical  programs  beyond  those  currently  contemplated,  and  to  scale  up  manufacturing  processes  for  our
product candidates. However, the actual amount of funds that we will need will be determined by many factors, some of which are beyond our control. These
factors include, without limitation:

·

·

·

·

·

the scope of our, or our partners’, clinical trials, which is significantly influenced by the quality of clinical data achieved as trials are completed
and the requirements established by regulatory authorities;
the speed with which we, or our partners, complete our clinical trials, which depends on our ability to attract and enroll qualifying patients and
the quality of the work performed by our clinical investigators and contract research organizations chosen to conduct the studies;
the time required to prosecute, enforce and defend our intellectual property rights, which depends on evolving legal regimes and infringement
claims that may arise between us and third parties;
the ability to manufacture at scales sufficient to supply commercial quantities of any of our product candidates that receive regulatory approval,
which may require levels of effort not currently anticipated; and
the successful commercialization of our product candidates, which will depend on our, or our partners’, ability to either create or partner with an
effective commercialization organization and which could be delayed or prevented by the emergence of equal or more effective therapies.

Emerging biotechnology companies like us may raise capital through corporate collaborations and by licensing intellectual property rights to other
biotechnology or pharmaceutical enterprises. We intend to pursue this strategy, but there can be no assurance that we will be able to enter into additional
license  agreements  with  respect  to  our  intellectual  property  or  product  development  programs  on  commercially  reasonable  terms,  if  at  all.  There  are
substantial challenges and risks that will make it difficult to successfully implement any of these alternatives. If we are successful in raising additional capital
through such a license or collaboration, we may have to give up valuable rights to our intellectual property. In addition, the business priorities of a strategic
partner may change over time, which creates the possibility that the interests of the strategic partner in developing our technology may diminish and could
have a potentially material negative impact on the value of our interest in the licensed intellectual property or product candidates.

Further, if we raise additional funds by selling shares of our common stock or securities convertible into our common stock the ownership interest of
our existing stockholders may be significantly diluted. If additional funds are raised through the issuance of preferred stock or debt securities, these securities
are likely to have rights, preferences and privileges senior to our common stock and may involve significant fees, interest expense, restrictive covenants or the
granting of security interests in our assets.

Our failure to successfully address our short-term capital needs and our long-term liquidity requirements would have a material negative impact on
our  business,  including  the  possibility  of  surrendering  our  rights  to  some  technologies  or  product  opportunities,  delaying  our  clinical  trials  or  ceasing  our
operations.

14

 
 
 
 
 
 
 
 
 
 
 
 
 
We have incurred losses since inception and expect to incur significant losses in the foreseeable future and may never become profitable.

We have not commercialized any product candidates to date and incurred net operating losses every year since our inception in 1982. We believe
these losses will continue for the foreseeable future, and may increase, as we pursue our product development efforts related to Tß4. As of December 31,
2018, our accumulated deficit totaled approximately $106 million.

As we expand our research and development efforts and seek to obtain regulatory approval of our product candidates to make them commercially
viable, we anticipate substantial and increasing operating losses. Our ability to generate revenues and to become profitable will depend largely on our ability,
alone or through the efforts of third-party licensees and collaborators, to efficiently and successfully complete the development of our product candidates,
obtain necessary regulatory approvals for commercialization, scale-up commercial quantity manufacturing capabilities either internally or through third-party
suppliers, and market our product candidates. There can be no assurance that we will achieve any of these objectives or that we will ever become profitable or
be able to maintain profitability. Even if we do achieve profitability, we cannot predict the level of such profitability. If we continue to sustain losses over an
extended  period  of  time  and  are  not  otherwise  able  to  raise  necessary  funds  to  continue  our  development  efforts  and  maintain  our  operations,  we  may  be
forced to cease operations.

Our  common  stock  is  quoted  on  the  over-the-counter  market,  which  subjects  us  to  the  SEC’s  penny  stock  rules  and  may  decrease  the  liquidity  of  our
common stock.

Our  common  stock  is  traded  over-the-counter  on  the  OTC  Bulletin  Board.  Over-the-counter  markets  are  generally  considered  to  be  less  efficient
than, and not as broad as, a stock exchange. There may be a limited market for our stock now that it is quoted on the OTC Bulletin Board, trading in our stock
may become more difficult and our share price could decrease. Specifically, you may not be able to resell your shares of common stock at or above the price
you paid for such shares or at all.

In addition, our ability to raise additional capital may be impaired because of the less liquid nature of the over-the-counter markets. While we cannot
guarantee that we would be able to complete an equity financing on acceptable terms, or at all, we believe that dilution from any equity financing while our
shares are quoted on an over-the-counter market would likely be substantially greater than if we were to complete a financing while our common stock is
traded on a national securities exchange. Further, we are unable to use short-form registration statements on Form S-3 for the registration of our securities,
which could impair our ability to raise additional capital as needed.

Our common stock is also subject to penny stock rules, which impose additional sales practice requirements on broker-dealers who sell our common
stock. The SEC generally defines “penny stock” as an equity security that has a market price of less than $5.00 per share, subject to certain exceptions. The
ability of broker-dealers to sell our common stock and the ability of our stockholders to sell their shares in the secondary market will be limited and, as a
result, the market liquidity for our common stock will likely be adversely affected. We cannot assure you that trading in our securities will not be subject to
these or other regulations in the future.

The report of our independent registered public accounting firm contains explanatory language that substantial doubt exists about our ability to continue
as a going concern.

The  report  of  our  independent  registered  public  accounting  firm  on  our  financial  statements  for  the  year  ended  December  31,  2018,  contains
explanatory language that substantial doubt exists about our ability to continue as a going concern, without raising additional capital. As described in this
report, in February 2019, we sold a series of convertible promissory notes to accredited investors and will receive gross proceeds of $1,300,000 which will
fund planned operations through the first quarter of 2020. We will need to secure additional operating capital to continue operations beyond the first quarter of
2020. Therefore, we are seeking sources of capital, but if we are unable to obtain sufficient financing to support and complete these activities, then we would,
in all likelihood, experience severe liquidity problems and may have to curtail our operations. If we curtail our operations, we may be placed into bankruptcy
or undergo liquidation, the result of which will adversely affect the value of our common shares.

Risks Related to Our Business and Operations

Our planned Phase 2 clinical trial of RGN-352 was placed on clinical hold by the FDA in March 2011 due to non-compliance of cGMP regulations by a
contract manufacturer and we are unsure when, if ever, we will be able to resume this trial.

In the second half of 2010, we implemented the development plans for our Phase 2 clinical trial to evaluate RGN-352 in patients who have suffered
an acute myocardial infarction, or AMI. We had planned to begin enrolling patients near the end of the first quarter of 2011. However, in March 2011, we
were notified by the FDA that the trial was placed on clinical hold as a result of our contract manufacturer’s alleged failure to comply with current Good
Manufacturing Practice (“cGMP”) regulations. The FDA has prohibited us from using any of the active drug or placebo manufactured by this manufacturer in
human trials, which will require us to identify a cGMP-compliant manufacturer and to have new material produced in the event that we seek to resume this
trial. We learned that the contract manufacturer has closed its manufacturing facility and has filed for bankruptcy protection. Significant preparatory time and
procedures will be required before any new suitable manufacturer would be able to manufacture RGN-352 for the AMI trial. Since we are unable to estimate
the length of time that the trial will be on clinical hold, we have elected to cease activities on this trial until the FDA clinical hold is resolved and the requisite
funding might be secured. Consequently, there can be no assurance that we will be able to timely initiate trial activities or complete this trial, if at all. As of
the date of this report, we have received no new information on that status of this trial.

All of our drug candidates are based on a single compound.

Our current primary business focus is the development of Tß4, and its analogues, derivatives and fragments, for the regeneration and accelerated
repair of damaged tissue from non-healing dermal and corneal wounds, cardiac injury, central/peripheral nervous system diseases and other conditions, as
well as an improvement in various functions, such as, but not limited to, cardiac and neurological. Unlike many pharmaceutical companies that have a number
of unique chemical entities in development, we are dependent on a single molecule, formulated for different routes of administration and different clinical
indications, for our potential commercial success. As a result, any common safety or efficacy concerns for Tß4-based products that cross formulations would
have a much greater impact on our business prospects than if our product pipeline were more diversified.

We may never be able to commercialize our product candidates.

Although Tß4 has shown biological activity in in vitro studies and in vivo  animal  models  and  while  we  observed  clinical  activity  and  efficacious
outcomes in our recent RGN-259 Phase 2a trial and earlier Phase 2 dermal trials, we cannot assure you that our product candidates will exhibit activity or
importance in humans in large-scale trials. Our drug candidates are still in research and development, and we do not expect them to be commercially available
for the foreseeable future, if at all. Only a small number of research and development programs ultimately result in commercially successful drugs. Potential
products that appear to be promising at early stages of development may not reach the market for a number of reasons. These include the possibility that the
potential products may:

·
·
·
·
·

be found ineffective or cause harmful side effects during preclinical studies or clinical trials;
fail to receive necessary regulatory approvals;
be precluded from commercialization by proprietary rights of third parties;
be difficult to manufacture on a large scale; or
be uneconomical or otherwise fail to achieve market acceptance.

If any of these potential problems occurs, we may never successfully market Tß4-based products.

We are subject to intense government regulation, and we may not receive regulatory approvals for our drug candidates.

Our product candidates will require regulatory approvals prior to sale. In particular, therapeutic agents are subject to stringent approval processes,
prior to commercial marketing, by the FDA and by comparable agencies in most foreign countries. The process of obtaining FDA and corresponding foreign
approvals  is  costly  and  time-consuming,  and  we  cannot  assure  you  that  such  approvals  will  be  granted.  Also,  the  regulations  we  are  subject  to  change
frequently and such changes could cause delays in the development of our product candidates.

Three of our drug candidates are currently in the clinical development stage, and we cannot be certain that we, or our partners, will successfully
complete the clinical trials necessary to receive regulatory product approvals. The regulatory approval process is lengthy, unpredictable and expensive. To
obtain regulatory approvals in the United States, we or a partner must ultimately demonstrate to the satisfaction of the FDA that our product candidates are
sufficiently safe and effective for their proposed administration to humans. Many factors, known and unknown, can adversely impact clinical trials and the
ability to evaluate a product candidate’s safety and efficacy, including:

·

·

the FDA or other health regulatory authorities, or institutional review boards, or IRBs, do not approve a clinical trial protocol or place a clinical
trial on hold;
suitable  patients  do  not  enroll  in  a  clinical  trial  in  sufficient  numbers  or  at  the  expected  rate,  for  reasons  such  as  the  size  of  the  patient
population, the proximity of patients to clinical sites, the eligibility criteria for the trial, the perceptions of investigators and patients regarding
safety, and the availability of other treatment options;

·

·

clinical trial data is adversely affected by trial conduct or patient withdrawal prior to completion of the trial;
there may be competition with ongoing clinical trials and scheduling conflicts with participating clinicians;
patients experience serious adverse events, including adverse side effects of our drug candidates, for a variety of reasons that may or may not be
related to our product candidates, including the advanced stage of their disease and other medical problems;
patients in the placebo or untreated control group exhibit greater than expected improvements or fewer than expected adverse events;
third-party clinical investigators do not perform the clinical trials on the anticipated schedule or consistent with the clinical trial protocol and
good clinical practices, or other third-party organizations do not perform data collection and analysis in a timely or accurate manner;
service providers, collaborators or co-sponsors do not adequately perform their obligations in relation to the clinical trial or cause the trial to be
delayed or terminated;
we are unable to obtain a sufficient supply of manufactured clinical trial materials;
regulatory inspections of manufacturing facilities, which may, among other things, require us or a co-sponsor to undertake corrective action or
suspend the clinical trials, such as the clinical hold with respect to our Phase 2 clinical trial of RGN-352;
the interim results of the clinical trial are inconclusive or negative;
the clinical  trial,  although  approved  and  completed,  generates  data  that  is  not  considered  by  the  FDA  or  others  to  be  clinically  relevant  or
sufficient to demonstrate safety and efficacy; and
changes in governmental regulations or administrative actions affect the conduct of the clinical trial or the interpretation of its results.

There  can  be  no  assurance  that  our,  or  our  partners’,  clinical  trials  will  in  fact  demonstrate,  to  the  satisfaction  of  the  FDA  and  others,  that  our
product candidates are sufficiently safe or effective. The FDA or we may also restrict or suspend our clinical trials at any time if it is believed that subjects
participating in the trials are being exposed to unacceptable health risks.

Clinical trials for product candidates such as ours are often conducted with patients who have more advanced forms of a particular condition or other
unrelated conditions. For example, in clinical trials for our product candidate RGN-137, we have studied patients who are not only suffering from chronic
epidermal wounds but who are also older and much more likely to have other serious adverse conditions. During the course of treatment with our product
candidates, patients could die or suffer other adverse events for reasons that may or may not be related to the drug candidate being tested. Further, and as a
consequence that all of our drug candidates are based on Tß4, crossover risk exists such that a patient in one trial may be adversely impacted by one drug
candidate, and that adverse event may have implications for our other trials and other drug candidates. However, even if unrelated to our product candidates,
such adverse events can nevertheless negatively impact our clinical trials, and our business prospects would suffer.

These factors, many of which may be outside of our control, may have a negative impact on our business by making it difficult to advance product
candidates or by reducing or eliminating their potential or perceived value. As a consequence, we may need to perform more or larger clinical trials than
planned. Further, if we are forced to contribute greater financial and clinical resources to a study, valuable resources will be diverted from other areas of our
business. If we fail to complete or if we experience material delays in completing our clinical trials as currently planned, or we otherwise fail to commence or
complete, or experience delays in, any of our other present or planned clinical trials, including as a result of the actions of third parties upon which we rely for
these functions, our ability to conduct our business as currently planned could materially suffer.

We may not successfully establish and maintain development and testing relationships with third-party service providers and collaborators, which could
adversely affect our ability to develop our product candidates.

We have only limited resources, experience with and capacity to conduct requisite testing and clinical trials of our drug candidates. As a result, we
rely  and  expect  to  continue  to  rely  on  third-party  service  providers  and  collaborators,  including  corporate  partners,  licensors  and  contract  research
organizations, or CROs, to perform a number of activities relating to the development of our drug candidates, including the design and conduct of clinical
trials, and potentially the obtaining of regulatory approvals. For example, we currently rely on several third-party contractors to manufacture and formulate
Tß4  into  the  product  candidates  used  in  our  clinical  trials,  develop  assays  to  assess  Tß4’s  effectiveness  in  complex  biological  systems,  recruit  clinical
investigators and sites to participate in our trials, manage the clinical trial process and collect, evaluate and report clinical results.

17

 
 
 
 
 
 
 
 
We may not be able to maintain or expand our current arrangements with these third parties or maintain such relationships on favorable terms. Our
agreements with these third parties may also contain provisions that restrict our ability to develop and test our product candidates or that give third parties
rights  to  control  aspects  of  our  product  development  and  clinical  programs.  In  addition,  conflicts  may  arise  with  our  collaborators,  such  as  conflicts
concerning the interpretation of clinical data, the achievement of milestones, the interpretation of financial provisions or the ownership of intellectual property
developed during the collaboration. If any conflicts arise with our existing or future collaborators, they may act in their self-interest, which may be adverse to
our best interests. Any failure to maintain our collaborative agreements and any conflicts with our collaborators could delay or prevent us from developing
our product candidates. We and our collaborators may fail to develop products covered by our present and future collaborations if, among other things:

·
·
·
·
·
·

we or our partners do not achieve our objectives under our collaboration agreements;
we or our partners are unable to obtain patent protection for the products or proprietary technologies we develop in our partnerships;
we are unable to manage multiple simultaneous product development partnerships;
our partners become competitors of ours or enter into agreements with our competitors;
we or our partners encounter regulatory hurdles that prevent commercialization of our product candidates; or
we develop products and processes or enter into additional partnerships that conflict with the business objectives of our other partners.

We also have less control over the timing and other aspects of our clinical trials than if we conducted the monitoring and supervision entirely on our
own.  Third  parties  may  not  perform  their  responsibilities  for  our  clinical  trials  on  our  anticipated  schedule  or  consistent  with  a  clinical  trial  protocol  or
applicable regulations. We, and our partners, also rely on clinical research organizations to perform much of our data management and analysis. They may not
provide  these  services  as  required  or  in  a  timely  manner.  If  any  of  these  parties  do  not  meet  deadlines  or  follow  proper  procedures,  including  procedures
required  by  law,  the  preclinical  studies  and  clinical  trials  may  take  longer  than  expected,  may  be  delayed  or  may  be  terminated,  which  would  have  a
materially negative impact on our product development efforts. If we were forced to find a replacement entity to perform any of our preclinical studies or
clinical trials, we may not be able to find a suitable entity on favorable terms or at all. Even if we were able to find a replacement, resulting delays in the tests
or trials may result in significant additional expenditures and delays in obtaining regulatory approval for drug candidates, which could have a material adverse
impact on our results of operations and business prospects.

GtreeBNT Co., Ltd. has limited drug development experience.

We are a party to several license agreements and a Joint Venture with GtreeBNT. Historically, GtreeBNT’s business focus has been in the IT software
industry in Korea with strong IP positions addressing specific software tools and apps such as optimized multimedia software for smart phones. GtreeBNT
made  a  strategic  decision  in  November  2013  to  expand  into  the  biopharmaceutical  business  through  selected  strategic  alliances  with  biopharmaceutical
companies in the U.S. and EU. The collaboration with RegeneRx is the first strategic investment in this initiative. While GtreeBNT has hired executives and
staff  with  significant  pharmaceutical  experience,  the  company  has  no  internal  drug  development  experience.  As  a  result,  GtreeBNT  may  face  more  and
different challenges in the development of these product candidates than would more established pharmaceutical companies.

GtreeBNT Co., Ltd. has limited financial resources.

GtreeBNT  has  informed  us  that  they  have  limited  financial  resources.  They  have  to  continuously  raise  capital  to  fund  research,  development,
clinical trials, and operations. Therefore, their ability to finance each of these areas is subject to its ability to secured adequate capital. While GtreeBNT has
been able to finance each of these areas, to date, there is no assurance that they will be able to do so in the future. If GtreeBNT is unable to secure necessary
financing to fund clinical trials or operations, it could have a material adverse impact on RGN-137 and RGN-259 and RegeneRx’s ability to continue funding
operations while these products are under development.

We are subject to intense competition from companies with greater resources and more mature products, which may result in our competitors developing
or commercializing products before or more successfully than we do.

We are engaged in a business that is highly competitive. Research and development activities for the development of drugs to treat indications within
our focus are being sponsored or conducted by private and public research institutions and by major pharmaceutical companies located in the United States
and a number of foreign countries. Most of these companies and institutions have financial and human resources that are substantially greater than our own
and they have extensive experience in conducting research and development activities and clinical trials and in obtaining the regulatory approvals necessary
to market pharmaceutical products that we do not have. As a result, they may develop competing products more rapidly that are safer, more effective, or have
fewer side effects, or are less expensive, or they may develop and commercialize products that render our product candidates non-competitive or obsolete.

With respect to our product candidate RGN-259, there are also numerous ophthalmic companies developing drugs for corneal wound healing and
other front-of-the-eye diseases and injuries, including dry eye syndrome. Amniotic membranes have been successfully used to treat corneal wounds in certain
cases, as have topical steroids and antibacterial agents. Most specialty ophthalmic companies have a number of products on the market that could compete
with RGN-259. There are numerous antibiotics to treat eye infections to promote corneal wound healing and many eye lubrication products that are soothing
to the eye and help eye healing, many of which are sold without prescriptions. Companies also market steroids to treat certain conditions within our area of
interest. Allergan, Inc. markets Restasis™, Ophthalmic Emulsion, which was the only commercially available and FDA-approved eye drop to treat dry eye.
Shire  PLC  recently  received  FDA  approval  to  market  Xiidra™  for  the  treatment  of  dry  eye  and  has  launched  the  product  in  the  U.S.  Restasis,  and  other
products, have been approved for marketing in certain other countries where we have licensed RGN-259.

We have initially targeted our product candidate RGN-352 for cardiovascular indications. Most large pharmaceutical companies and many smaller

biomedical companies are vigorously pursuing the development of therapeutics to treat patients after heart attacks and for other cardiovascular indications.

With respect to our product candidate RGN-137 for wound healing, Johnson & Johnson has previously marketed Regranex™ for this purpose in
patients with diabetic foot ulcers. Other companies, such as Novartis, are developing and marketing artificial skins, which we believe could also compete with
RGN-137.  Other  companies  are  developing  genetic  therapies  to  treat  wound  healing  of  the  skin  and  internal  organs.  Wound  healing  is  a  large  and  highly
fragmented  marketplace  attracting  many  companies,  large  and  small,  to  develop  products  for  treating  acute  and  chronic  wounds,  including,  for  example,
honey-based ointments, hyperbaric oxygen therapy, and low frequency cavitational ultrasound.

We are also interested in developing potential cosmeceutical products, which are loosely defined as products that bridge the gap between cosmetics
and  pharmaceuticals,  for  example,  by  improving  skin  texture  and  reducing  the  appearance  of  aging.  This  industry  is  intensely  competitive,  with  potential
competitors ranging from large multinational companies to very small specialty companies. New cosmeceutical products often have a short product life and
are frequently replaced with newer products developed to address the latest trends in appearance and fashion. We may not be able to adapt to changes in the
industry as quickly as larger and more experienced cosmeceutical companies. Further, larger cosmetics companies have the financial and marketing resources
to effectively compete with smaller companies like us in order to sell products aimed at larger markets.

Even if approved for marketing, our technologies and product candidates are unproven and they may fail to gain market acceptance.

Our product candidates, all of which are based on the molecule Tß4, are new and unproven and there is no guarantee that health care providers or
patients will be interested in our product candidates, even if they are approved for use. If any of our product candidates are approved by the FDA, our success
will  depend  in  part  on  our  ability  to  demonstrate  sufficient  clinical  benefits,  reliability,  safety,  and  cost  effectiveness  of  our,  or  our  partners’,  product
candidates relative to other approaches, as well as on our ability to continue to develop our product candidates to respond to competitive and technological
changes. If the market does not accept our product candidates, when and if we are able to commercialize them, then we may never become profitable. Factors
that could delay, inhibit or prevent market acceptance of our product candidates may include:

·
·
·
·
·

the timing and receipt of marketing approvals;
the safety and efficacy of the products;
the emergence of equivalent or superior products;
the cost-effectiveness of the products; and
ineffective marketing.

It is difficult to predict the future growth of our business, if any, and the size of the market for our product candidates because the markets are
continually evolving. There can be no assurance that our product candidates will prove superior to products that may currently be available or may become
available in the future or that our research and development activities will result in any commercially profitable products.

We  have  no  marketing  experience,  sales  force  or  distribution  capabilities.  If  our  product  candidates  are  approved,  and  we  are  unable  to  recruit  key
personnel to perform these functions, we may not be able to commercialize them successfully.

Although we do not currently have any marketable products, our ability to produce revenues ultimately depends on our, or our partners’, ability to
sell our product candidates if and when they are approved by the FDA and other regulatory authorities. We currently have no experience in marketing or
selling pharmaceutical products, and we do not have a marketing and sales staff or distribution capabilities. Developing a marketing and sales force is also
time-consuming and could delay the launch of new products or expansion of existing product sales. In addition, we will compete with many companies that
currently have extensive and well-funded marketing and sales operations. If we fail to establish successful marketing and sales capabilities or fail to enter into
successful marketing arrangements with third parties, our ability to generate revenues will suffer.

If  we  enter  markets  outside  the  United  States  our  business  will  be  subject  to  political,  economic,  legal  and  social  risks  in  those  markets,  which  could
adversely affect our business.

There are significant regulatory and legal barriers to entering markets outside the United States that must be overcome if we, or our partners, seek
regulatory approval to market our product candidates in countries other than the United States. We would be subject to the burden of complying with a wide
variety of national and local laws, including multiple and possibly overlapping and conflicting laws. We also may experience difficulties adapting to new
cultures,  business  customs  and  legal  systems.  Any  sales  and  operations  outside  the  United  States  would  be  subject  to  political,  economic  and  social
uncertainties including, among others:

·
·
·
·
·
·
·

changes and limits in import and export controls;
increases in custom duties and tariffs;
changes in currency exchange rates;
economic and political instability;
changes in government regulations and laws;
absence in some jurisdictions of effective laws to protect our intellectual property rights; and
currency transfer and other restrictions and regulations that may limit our ability to sell certain product candidates or repatriate profits to
the United States.

Any changes related to these and other factors could adversely affect our business if and to the extent we enter markets outside the United States.
Additionally,  we  have  entered  into  license  agreements  with  Lee’s  Pharmaceutical  Limited  and  GtreeBNT  Co,  Ltd.  for  the  development  of  certain  of  our
product  candidates  in  international  markets.  As  a  result,  these  development  activities  will  be  subject  to  compliance  in  all  respects  with  local  laws  and
regulations and may be subject to many of the risks described above.

Governmental and third-party payors may subject any product candidates we develop to sales and pharmaceutical pricing controls that could limit our
product revenues and delay profitability.

The  successful  commercialization  of  our  product  candidates,  if  they  are  approved  by  the  FDA,  will  likely  depend  on  our  ability  to  obtain
reimbursement for the cost of the product and treatment. Government authorities, private health insurers and other organizations, such as health maintenance
organizations,  are  increasingly  seeking  to  lower  the  prices  charged  for  medical  products  and  services. Also,  the  trend  toward  managed  health  care  in  the
United States, the growth of healthcare maintenance organizations, and recently enacted legislation reforming healthcare and proposals to reform government
insurance programs could have a significant influence on the purchase of healthcare services and products, resulting in lower prices and reducing demand for
our product candidates. The cost containment measures that healthcare providers are instituting, and any healthcare reform could reduce our ability to sell our
product  candidates  and  may  have  a  material  adverse  effect  on  our  operations.  We  cannot  assure  you  that  reimbursement  in  the  United  States  or  foreign
countries  will  be  available  for  any  of  our  product  candidates,  and  that  any  reimbursement  granted  will  be  maintained,  or  that  limits  on  reimbursement
available  from  third-party  payors  will  not  reduce  the  demand  for,  or  the  price  of,  our  product  candidates.  The  lack  or  inadequacy  of  third-party
reimbursements  for  our  product  candidates  would  decrease  the  potential  profitability  of  our  operations.  We  cannot  forecast  what  additional  legislation  or
regulation  relating  to  the  healthcare  industry  or  third-party  coverage  and  reimbursement  may  be  enacted  in  the  future,  or  what  effect  the  legislation  or
regulation would have on our business.

We have no manufacturing or formulation capabilities and are dependent upon third-party suppliers to provide us with our product candidates. If these
suppliers do not manufacture our product candidates in sufficient quantities, at acceptable quality levels and at acceptable cost, or if we are unable to
identify suitable replacement suppliers if needed, our clinical development efforts could be delayed, prevented or impaired.

We  do  not  own  or  operate  manufacturing  facilities  and  have  little  experience  in  manufacturing  pharmaceutical  products.  We  currently  rely,  and
expect to continue to rely, primarily on peptide manufacturers to supply us with Tß4 for further formulation into our product candidates. We have historically
engaged  three  separate  smaller  drug  formulation  contractors  for  the  formulation  of  clinical  grade  product  candidates,  one  for  each  of  our  three  product
candidates in clinical development, although, as described in this report, the contractor we engaged to formulate and vial RGN-352 has filed for bankruptcy
and  closed  its  manufacturing  facility,  and  our  clinical  trial  involving  RGN-352  has  been  placed  on  clinical  hold.  We  currently  do  not  have  an  alternative
source of supply for either Tß4 or the individual drug candidates. If these suppliers, together or individually, are not able to supply us with either Tß4 or
individual  product  candidates  on  a  timely  basis,  in  sufficient  quantities,  at  acceptable  levels  of  quality  and  at  a  competitive  price,  or  if  we  are  unable  to
identify a replacement manufacturer to perform these functions on acceptable terms as needed, our development programs could be seriously jeopardized.

The clinical hold on our RGN-352 trial will require us to have new material manufactured by a cGMP-compliant manufacturer in the event that we
seek to resume this trial. Significant preparatory time and procedures will be required before any new manufacturer would be able to manufacture RGN-352
for the AMI trial, due to the time required for revalidation of processes and assays related to such production that were already in place with the original
manufacturer. Since we are unable to estimate the length of time that the trial will be on clinical hold, we have elected to cease activities on this trial until the
FDA clinical hold is resolved and the requisite funding might be secured.

20

 
 
 
 
 
 
 
 
 
 
 
 
Other risks of relying solely on single suppliers for each of our product candidates include:

·

·

·
·
·

·
·

·

the possibility that our other manufacturers, and any new manufacturer that we, or our partners, may identify for RGN-352, may not be able to
ensure quality and compliance with regulations relating to the manufacture of pharmaceuticals;
their  manufacturing  capacity  may  not  be  sufficient  or  available  to  produce  the  required  quantities  of  our  product  candidates  based  on  our
planned clinical development schedule, if at all;
they may not have access to the capital necessary to expand their manufacturing facilities in response to our needs;
commissioning replacement suppliers would be difficult and time-consuming;
individual suppliers may have used substantial proprietary know-how relating to the manufacture of our product candidates and, in the event we
must find a replacement or supplemental supplier, our ability to transfer this know-how to the new supplier could be an expensive and/or time-
consuming process;
an individual supplier may experience events, such as a fire or natural disaster, that force it to stop or curtail production for an extended period;
an individual supplier could encounter significant increases in labor, capital or other costs that would make it difficult for them to produce our
products cost-effectively; or
an individual supplier may not be able to obtain the raw materials or validated drug containers in sufficient quantities, at acceptable costs or in
sufficient time to complete the manufacture, formulation and delivery of our product candidates.

Our  suppliers  may  use  hazardous  and  biological  materials  in  their  businesses.  Any  claims  relating  to  improper  handling,  storage  or  disposal  of  these
materials could be time-consuming and costly to us, and we are not insured against such claims.

Our product candidates and processes involve the controlled storage, use and disposal by our suppliers of certain hazardous and biological materials
and waste products. We and our suppliers and other collaborators are subject to federal, state and local regulations governing the use, manufacture, storage,
handling and disposal of materials and waste products. Even if we and these suppliers and collaborators comply with the standards prescribed by law and
regulation, the risk of accidental contamination or injury from hazardous materials cannot be completely eliminated. In the event of an accident, we could be
held liable for any damages that result, and we do not carry insurance for this type of claim. We may also incur significant costs to comply with current or
future environmental laws and regulations.

We face the risk of product liability claims, which could adversely affect our business and financial condition.

We, or our partners, may be subject to product liability claims as a result of our testing, manufacturing, and marketing of drugs. In addition, the use
of our product candidates, when and if developed and sold, will expose us to the risk of product liability claims. Product liability may result from harm to
patients  using  our  product  candidates,  such  as  a  complication  that  was  either  not  communicated  as  a  potential  side  effect  or  was  more  extreme  than
anticipated. We require all patients enrolled in our clinical trials to sign consents, which explain various risks involved with participating in the trial. However,
patient consents provide only a limited level of protection, and it may be alleged that the consent did not address or did not adequately address a risk that the
patient suffered. Additionally, we will generally be required to indemnify our clinical product manufacturers, clinical trial centers, medical professionals and
other parties conducting related activities in connection with losses they may incur through their involvement in the clinical trials.

Our ability to reduce our liability exposure for human clinical trials and commercial sales, if any, of Tß4 is dependent in part on our ability to obtain
sufficient  product  liability  insurance  or  to  collaborate  with  third  parties  that  have  adequate  insurance. Although  we  intend  to  obtain  and  maintain  product
liability insurance coverage if we gain approval to market any of our product candidates, we cannot guarantee that product liability insurance will continue to
be  available  to  us  on  acceptable  terms,  or  at  all,  or  that  its  coverage  will  be  sufficient  to  cover  all  claims  against  us.  A  product  liability  claim,  even  one
without  merit  or  for  which  we  have  substantial  coverage,  could  result  in  significant  legal  defense  costs,  thereby  potentially  exposing  us  to  expenses
significantly in excess of our revenues, as well as harm to our reputation and distraction of our management.

21

 
 
 
 
 
 
 
 
 
If any of our key employees discontinue their services with us, our efforts to develop our business may be delayed.

We are highly dependent on the principal members of our management team. The loss of our chairman and Chief Scientific Officer, Allan Goldstein,
or chief executive officer, J.J. Finkelstein could prevent or significantly delay the achievement of our goals. We cannot assure you that Dr. Goldstein or Mr.
Finkelstein,  or  any  other  key  employees  or  consultants,  will  not  elect  to  terminate  their  employment  or  consulting  arrangements.  In  addition,  we  do  not
maintain  a  key  man  life  insurance  policy  with  respect  to  any  of  our  management  personnel.  In  the  future,  we  anticipate  that  we  will  also  need  to  add
additional management and other personnel. Competition for qualified personnel in our industry is intense, and our success will depend in part on our ability
to attract and retain highly skilled personnel. We cannot assure you that our efforts to attract or retain such personnel will be successful.

Mauro Bove, a member of our Board is a director of Lee’s Pharmaceuticals, a relationship which could give rise to a conflict of interest for Mr. Bove.

Mauro Bove is a member of our Board of Directors and currently provides consulting services to Lee’s Pharmaceuticals Group in Hong Kong. There
can be no assurance that we will ever receive any further payments from Lee’s under the current agreement established between RegeneRx and Lee’s. As a
result of Mr. Bove’s relationship with Lee’s, Mr. Bove may have interests that are different from our other stockholders in connection with this agreement and
circumstances that may require the exercise of the Board’s discretion with respect to Lee’s.

Risks Related To Our Intellectual Property

We may not be able to maintain broad patent protection for our product candidates, which could limit the commercial potential of our product candidates.

Our success will depend in part on our, or our partners’ ability to obtain, defend and enforce patents, both in the United States and abroad. We have
attempted  to  create  a  substantial  intellectual  property  portfolio,  submitting  patent  applications  for  various  compositions  of  matter,  methods  of  use  and
fragments and derivatives of Tß4. As described elsewhere in this report, we currently do not have adequate financial resources to fund our ongoing business
activities  beyond  the  first  quarter  of  2020  without  additional  funding.  Thus,  we  continuously  evaluate  our  issued  patents  and  patent  applications  and  may
decide to limit their therapeutic and/or geographic coverage in an effort to enhance our ability to focus on certain medical conditions and countries within our
financial constraints. As a result, we may not be able to protect our intellectual property rights in indications and/or territories that we otherwise would, and,
therefore,  our  ability  to  commercialize  Tß4,  if  at  all,  could  be  substantially  limited,  which  could  have  a  material  adverse  impact  on  our  future  results  of
operations.

Our patents may expire before any of our product candidates reach commercialization.

Our success will depend in part on our, or our partners’ patents to provide market exclusivity for our product candidates. We have numerous patent
and  patent  applications  in  the  U.S.  and  abroad,  however,  some  of  our  patents  are  reaching  the  end  of  their  20-year  patent  exclusivity  and,  therefore,  may
expire prior to developing any marketable products or expire shortly after product launch, which could negatively affect our commercial success.

If we, or our partners, are not able to maintain adequate patent protection for our product candidates, we may be unable to prevent our competitors from
using our technology or technology that we license.

Our success will depend in substantial part on our, or our partners’, abilities to obtain, defend and enforce patents, maintain trade secrets and operate
without infringing upon the proprietary rights of others, both in the United States and abroad. Pursuant to an exclusive worldwide license from the NIH, we
have exclusive rights to use Tß4 in the treatment of non-healing wounds. While patents covering our use of Tß4 have issued in some countries, we cannot
guarantee whether or when corresponding patents will be issued, or the scope of any patents that may be issued, in other countries. We have attempted to
create  a  substantial  intellectual  property  portfolio,  submitting  patent  applications  for  various  compositions  of  matter,  methods  of  use  and  fragments  and
derivatives of Tß4. We have also in-licensed other intellectual property rights from third parties that could be subject to the same risks as our own patents. If
any of these patent applications do not issue, or do not issue in certain countries, or are not enforceable, the ability to commercialize Tß4 in various medical
indications could be substantially limited or eliminated.

In addition, the patent positions of the products being developed by us and our collaborators involve complex legal and factual uncertainties. As a
result, we cannot assure you that any patent applications filed by us, or by others under which we have rights, will result in patents being issued in the United
States or foreign countries. In addition, there can be no assurance that any patents will be issued from any pending or future patent applications of ours or our
partners, that the scope of any patent protection will be sufficient to provide us with competitive advantages, that any patents obtained by us or our partners
will be held valid if subsequently challenged or that others will not claim rights in or ownership of the patents and other proprietary rights we or our partners
may hold. Unauthorized parties may try to copy aspects of our product candidates and technologies or obtain and use information we consider proprietary.
Policing the unauthorized use of our proprietary rights is difficult. We cannot guarantee that no harm or threat will be made to our or our partners’ intellectual
property. In addition, changes in, or different interpretations of, patent laws in the United States and other countries may also adversely affect the scope of our
patent protection and our competitive situation.

22

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Due to the significant time lag between the filing of patent applications and the publication of such patents, we cannot be certain that our licensors
were the first to file the patent applications we license or, even if they were the first to file, also were the first to invent, particularly with regards to patent
rights  in  the  United  States.  In  addition,  a  number  of  pharmaceutical  and  biotechnology  companies  and  research  and  academic  institutions  have  developed
technologies, filed patent applications or received patents on various technologies that may be related to our product candidates. Some of these technologies,
applications or patents may conflict with our or our licensors’ technologies or patent applications. A conflict could limit the scope of the patents, if any, that
we or our licensors may be able to obtain or result in denial of our or our licensors’ patent applications. If patents that cover our activities are issued to other
companies, we may not be able to develop or obtain alternative technology.

Additionally,  there  is  certain  subject  matter  that  is  patentable  in  the  United  States  but  not  generally  patentable  outside  of  the  United  States.
Differences  in  what  constitutes  patentable  subject  matter  in  various  countries  may  limit  the  protection  we  can  obtain  outside  of  the  United  States.  For
example, methods of treating humans are not patentable in many countries outside of the United States. These and other issues may prevent us from obtaining
patent protection outside of the United States, which would have a material adverse effect on our business, financial condition and results of operations.

Changes to U.S. patent laws could materially reduce any value our patent portfolio may have.

The value of our patents depends in part on their duration. A shorter period of patent protection could lessen the value of our rights under any patents
that may be obtained and may decrease revenues derived from its patents. For example, the U.S. patent laws were previously amended to change the term of
patent protection from 17 years following patent issuance to 20 years from the earliest effective filing date of the application. Because the time from filing to
issuance of biotechnology applications may be more than three years depending on the subject matter, a 20-year patent term from the filing date may result in
substantially shorter patent protection. Moreover, a divisional patent that is filed after a parent patent, if granted, would begin its term beginning when the
parent patent was initially filed, thus having an impact on the divisional patent’s practical patent life, Future changes to patent laws could shorten our period
of patent exclusivity and may decrease the revenues that we might derive from the patents and the value of our patent portfolio.

We, or our partners, may not have adequate protection for our unpatented proprietary information, which could adversely affect our competitive position.

In  addition  to  our  patents,  we,  and  our  partners,  also  rely  on  trade  secrets,  know-how,  continuing  technological  innovations  and  licensing
opportunities to develop and maintain our competitive position. However, others may independently develop substantially equivalent proprietary information
and  techniques  or  otherwise  gain  access  to  our  trade  secrets  or  disclose  our  technology.  To  protect  our  trade  secrets,  we  may  enter  into  confidentiality
agreements with employees, consultants and potential collaborators. However, we may not have such agreements in place with all such parties and, where we
do, these agreements may not provide meaningful protection of our trade secrets or adequate remedies in the event of unauthorized use or disclosure of such
information. Also, our trade secrets or know-how may become known through other means or be independently discovered by our competitors. Any of these
events could prevent us from developing or commercializing our product candidates.

We may be subject to claims that we or our employees have wrongfully used or disclosed alleged trade secrets of former employers.

As is commonplace in the biotechnology industry, we employ now, and may hire in the future, individuals who were previously employed at other
biotechnology or pharmaceutical companies, including competitors or potential competitors. Although there are no claims currently pending against us, we
may  be  subject  to  claims  that  we  or  certain  employees  have  inadvertently  or  otherwise  used  or  disclosed  trade  secrets  or  other  proprietary  information  of
former employers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could
result in substantial costs and would be a significant distraction to management.

Risks Related To Our Securities

Our common stock price is volatile, our stock is highly illiquid, and any investment in our securities could decline substantially in value.

For the period from January 1, 2018 through March 15, 2019 the closing price of our common stock has ranged from $0.09 to $0.35, with an average
daily trading volume of approximately 55,000 shares. In light of our small size and limited resources, as well as the uncertainties and risks that can affect our
business and industry, our stock price is expected to continue to be highly volatile and can be subject to substantial drops, with or even in the absence of news
affecting our business. The following factors, in addition to the other risk factors described in this report, and the potentially low volume of trades in our
common stock since it is not listed on a national securities exchange, may have a significant impact on the market price of our common stock, some of which
are beyond our control:

results of pre-clinical studies and clinical trials;
commercial success of approved products;
corporate partnerships;
technological innovations by us or competitors;
changes in laws and government regulations both in the U.S. and overseas;
changes in key personnel at our company;
developments concerning proprietary rights, including patents and litigation matters;
public perception relating to the commercial value or safety of any of our product candidates;
other issuances of our common stock, or securities convertible into or exercisable for our common stock, causing dilution;
anticipated or unanticipated changes in our financial performance;
general trends related to the biopharmaceutical and biotechnological industries; and
general conditions in the stock market.

The stock market in general has recently experienced relatively large price and volume fluctuations. In particular, the market prices of securities of
smaller biotechnology companies have experienced dramatic fluctuations that often have been unrelated or disproportionate to the operating results of these
companies. Continued market fluctuations could result in extreme volatility in the price of our common stock, which could cause a decline in its value. You
should also be aware that price volatility may be worse if the trading volume of the common stock remains limited or declines.

Our principal stockholders have significant voting power and may take actions that may not be in the best interests of our other stockholders.

Our officers, directors and principal stockholders together control approximately 50% of our outstanding common stock. Included in this group are
previous  stockholders  of  Sigma-Tau  and  their  affiliates,  which  now  have  consolidated  their  holding  into  Essetifin  S.p.A.  which  holds  outstanding  shares
representing  approximately  27%  of  our  outstanding  common  stock  and  GtreeBNT  which  owns  approximately  15.1%  of  our  outstanding  common  stock.
These  stockholders  also  hold  options,  warrants,  convertible  promissory  notes  and  stock  purchase  rights  that  provide  them  with  the  right  to  acquire
significantly more shares of common stock. Accordingly, if these stockholders acted together they could control the outcome of all stockholder votes. This
concentration of ownership may have the effect of delaying or preventing a change in control and might adversely affect the market price of our common
stock, and therefore may not be in the best interest of our other stockholders.

If securities or industry analysts do not publish research or reports or publish unfavorable research about our business, the price of our common stock
and other securities and their trading volume could decline.

The  trading  market  for  our  common  stock  and  other  securities  will  depend  in  part  on  the  research  and  reports  that  securities  or  industry  analysts
publish  about  us  or  our  business.  We  currently  have  research  coverage  by  one  securities  and  industry  analysts,  and  from  time  to  time  other  independent
analysts. If securities or industry analysts do not commence or maintain coverage of us, the trading price for our common stock and other securities would be
negatively affected. In the event one or more of the analysts who covers us downgrades our securities, the price of our securities would likely decline. If one
or more of these analysts ceases to cover us or fails to publish regular reports on us, interest in the purchase of our securities could decrease, which could
cause the price of our common stock and other securities and their trading volume to decline.

The exercise of options and warrants, conversion of convertible promissory notes, and other issuances of shares of common stock or securities convertible
into common stock will dilute your interest.

As of December 31, 2018, there were outstanding options to purchase an aggregate of 9,044,825 shares of our common stock under our 2000, 2010
and 2018 incentive equity plans at exercise prices ranging from $0.14 per share to $0.64 per share and outstanding warrants to purchase 4,220,594 shares of
our common stock at a weighted average exercise price of $0.24 per share. On February 27, 2019 we sold a series of convertible promissory notes that will
initially be convertible at $0.12 into 10,833,333 shares and also issued warrants to purchase 8,125,000 shares with an exercise price of $0.18 per share. In
March 2018 we entered into a warrant reprice and exercise and issuance agreement (the “Reprice Agreement”) with the holders of the warrants issued in June
2016. Under the terms of the Reprice Agreement, in consideration of the holders exercising in full all of the 2016 Offering warrants the exercise price per
share of 5,147,059 warrants was reduced to $0.20 per share. As further consideration, we issued to the holders of the 2016 Offering warrants 3,860,294 new
warrants with an exercise price of $0.2301 per share. Pursuant to the terms of the Reprice Agreement the exercise of the new warrants has been reduced to
$0.125 as a result of the February 2019 convertible note sale. In addition to the notes, options and warrants described above, we had previously issued five
series of convertible promissory notes of which one remained outstanding. In January 2014, we sold a series of convertible promissory notes, which notes
totaled $55,000 and are initially convertible into 916,667 shares of common stock at a conversion price of $0.06 per share. The notes matured in January 2019
and, along with the accrued interest were converted into common stock. The exercise of options and warrants or note conversions at prices below the market
price of our common stock could adversely affect the price of shares of our common stock. Additional dilution may result from the issuance of shares of our
capital stock in connection with collaborations or manufacturing arrangements or in connection with other financing efforts.

Any issuance of our common stock that is not made solely to then-existing stockholders proportionate to their interests, such as in the case of a stock
dividend or stock split, will result in dilution to each stockholder by reducing his, her or its percentage ownership of the total outstanding shares. Moreover, if
we issue options or warrants to purchase our common stock in the future and those options or warrants are exercised or we issue restricted stock, stockholders
may experience further dilution. Holders of shares of our common stock have no preemptive rights that entitle them to purchase their pro rata share of any
offering of shares of any class or series.

Our certificate of incorporation and Delaware law contain provisions that could discourage or prevent a takeover or other change in control, even if such
a transaction would be beneficial to our stockholders, which could affect our stock price adversely and prevent attempts by our stockholders to replace or
remove our current management.

Our certificate of incorporation provides our Board with the power to issue shares of preferred stock without stockholder approval. In addition, we
are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law. Subject to specified exceptions, this section provides that
a corporation may not engage in any business combination with any interested stockholder, as defined in that statute, during the three-year period following
the time that such stockholder becomes an interested stockholder. This provision could also have the effect of delaying or preventing a change of control of
our company. The foregoing factors could reduce the price that investors or an acquirer might be willing to pay in the future for shares of our common stock.

We may become involved in securities class action litigation that could divert management’s attention and harm our business and our insurance coverage
may not be sufficient to cover all costs and damages.

The stock market has from time to time experienced significant price and volume fluctuations that have affected the market prices for the common
stock of pharmaceutical and biotechnology companies. These broad market fluctuations may cause the market price of our common stock to decline. In the
past, following periods of volatility in the market price of a particular company’s securities, securities class action litigation has often been brought against
that company. If we experience this sort of volatility, we may become involved in this type of litigation in the future. Litigation often is expensive and diverts
management’s attention and resources, which could hurt our business, operating results and financial condition.

We  have  never  declared  or  paid  a  cash  dividend  on  our  common  stock  and  since  all  of  our  funds  are  committed  to  clinical  research  we  do  not

anticipate that any cash dividends will be paid on our common stock in the foreseeable future.

On February 27, 2019 we sold a series of convertible promissory notes to accredited investors including Essetifin S.p.A., our largest stockholder. The
sale  of  the  notes  will  result  in  gross  proceeds  to  the  Company  of  $1,300,000  over  two  closings.  The  first  closing  in  the  amount  of  $650,000  occurred  on
February 27th and the second closing, also in the amount of $650,000, will occur within three days of the Company providing notice of the enrollment of the
first patent in the ARISE-3 clinical trial in DES sponsored by ReGenTree. ReGenTree has informed us that they now expect the ARISE-3 clinical trial to
occur in the second quarter of 2019. Because the Company does not control the timing of the ARISE-3 clinical trial, we cannot be certain that this timing is
correct  or  that  it  may  not  change.  The  notes  contain  a  $0.12  conversion  price  and  are  initially  convertible  into  10,833,333  chares  off  common  stock.  The
purchasers also received a warrant exercisable at $0.18 to purchase additional 8,125,000 shares of common stock.

In January 2019, at note maturity, the holders of the January 2014 Notes elected to convert the note principal and accrued interest into shares of

common stock. As a result, the Company issued 1,149,016 shares of common stock.

In September 2018, at note maturity, the holders of the September 2013 Notes elected to convert the note principal and accrued interest into shares of

common stock. As a result, the Company issued 6,706,076 shares of common stock.

In July 2018, at note maturity, the holders of the July 2013 Notes elected to convert the note principal and accrued interest into shares of common

stock. As a result, the Company issued 2,089,120 shares of common stock.

In  March  2018,  at  note  maturity,  the  holders  of  the  March  2013  Notes  elected  to  convert  the  note  principal  and  accrued  interest  into  shares  of

common stock. As a result, the Company issued 4,700,520 shares of common stock.

On March 2, 2018 we entered into a warrant reprice and exercise and issuance agreement with the holders of the warrants issued in June 2016. Under
the  terms  of  the  Reprice  Agreement,  in  consideration  of  the  holders  exercising  in  full  all  of  the  2016  Offering  warrants  the  exercise  price  per  share  of
5,147,059 warrants was reduced to $0.20 per share. As further consideration, we issued to the holders of the 2016 Offering warrants 3,860,294 new warrants
with an exercise price of $0.2301 per share. Pursuant to the terms of the Reprice Agreement the exercise price of the new warrants will be reduced from
$0.2301 to $0.125 as a result of the February 2019 note sale.

In October 2017, at note maturity, the holders of the 2012 Convertible Notes elected to convert the note principal and accrued interest into shares of
common stock. The note holders also elected to exercise the warrants issued with the 2012 Convertible Notes. As a result, the Company issued 2,906,944
shares of common stock.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operation.

You should read the following discussion and analysis together with our financial statements and the related notes included elsewhere in this annual

report.

Business Overview

We  are  a  biopharmaceutical  company  focused  on  the  development  of  a  novel  therapeutic  peptide,  Thymosin  beta  4,  or  Tß4,  for  tissue  and  organ

protection, repair, and regeneration. We have formulated Tß4 into three distinct product candidates in clinical development:

•  RGN-259, a preservative-free topical eye drop for regeneration of corneal tissues damaged by injury, disease or other pathology;

•  RGN-352, an injectable formulation to treat cardiovascular diseases, central and peripheral nervous system diseases, and other medical indications

that may be treated by systemic administration; and

•  RGN-137, a topical gel for dermal wounds and reduction of scar tissue.

We are continuing strategic partnership discussions with biotechnology and pharmaceutical companies regarding the further clinical development of

all of our product candidates.

Current Financial Circumstances

On February 27, 2019 we sold a series of convertible promissory notes to management, the Board of Directors, and accredited investors, including
Essetifin S.p.A., our largest shareholder. The sale of the notes will result in gross proceeds to the Company of $1,300,000 over two closings. The first closing
in the amount of $650,000 occurred on February 27th and the second closing, also in the amount of $650,000, will occur within three days of the Company
providing notice of the enrolment of the first patent in the ARISE-3 clinical trial in DES sponsored by ReGenTree which is anticipated to occur in March
2019. The notes contain a $0.12 conversion price and the purchasers also received a warrant exercisable at $0.18 to purchase additional shares of common
stock equal to 75% of the number of shares into which each note is initially convertible. At present, with the receipt of the sale proceeds from the first closing
coupled with the anticipated proceeds from the second closing, we will have sufficient cash to fund planned operations through the first quarter of 2020.

On  March  2,  2018,  we  entered  into  a  warrant  reprice  and  exercise  and  issuance  agreement  (the  “Reprice  Agreement”)  with  the  holders  of  the
warrants issued in June 2016. Under the terms of the Reprice Agreement, in consideration of the holders exercising in full all of the 2016 Offering warrants,
the exercise price per share of the warrants was reduced to $0.20 per share. In addition, and as further consideration, we issued to the holders of the 2016
Offering warrants 3,860,294 new warrants with an exercise price of $0.2301 per share. Pursuant to the terms of the Reprice Agreement the exercise price of
the new warrants will be reduced from $0.2301 to $0.125 as a result of the February 2019 note sale. We continuously monitor our cash use as well as the
clinical timelines. We continue to evaluate options including the licensing of additional rights to commercialize our clinical products as well as raising capital
through the capital markets.

Current Clinical Status

In  January  2015,  we  entered  into  a  Joint  Venture  Agreement  with  GtreeBNT  whereby  we  created  ReGenTree  LLC,  (“ReGenTree”  or  “Joint
Venture”,  jointly  owned  by  us  and  GtreeBNT,  which  will  commercialize  RGN-259  for  treatment  of  dry  eye  and  neurotrophic  keratopathy,  an  orphan
indication in the United States. We are entitled to royalties as a percentage of net sales ranging from single digits to low-double digits based on the medical
indications approved and whether the Joint Venture commercializes products directly or through a third party. RegeneRx possesses one of three board seats of
ReGenTree  and  certain  major  decisions  and  transactions  within  ReGenTree,  such  as  commercialization  strategy,  mergers,  and  acquisitions,  require
RegeneRx’s board designee’s consent. We currently hold a 38.5% ownership interest in ReGenTree. This ownership interest may be further reduced to as low
as 25% once ReGenTree obtains FDA approval of an NDA for Dry Eye Syndrome in the U.S. In the event ReGenTree is acquired, or a change of control
occurs  following  achievement  of  an  NDA,  RegeneRx  shall  be  entitled  to  a  minimum  of  40%  of  all  proceeds  paid  or  payable  and  will  forgo  any  future
royalties.

To  date  ReGenTree  has  sponsored  a  Phase  2/3  clinical  trial  (“ARISE-1”)  and  Phase  3  clinical  trials  in  patients  with  dry  eye  syndrome  (“DES”)
(“ARISE-2”)  and  in  patients  with  neurotrophic  keratopathy  (“NK”)  (“SEER-1”),  all  in  the  U.S.  In  May  2016,  we  reported  the  results  of  the  317-patient
ARISE-1 trial and in October 2017, we reported the results of the ARISE-2 trial. The ARISE-2 study, which was sponsored by ReGenTree and managed by
Ora,  Inc.,  demonstrated  a  number  of  statistically  significant  improvements  in  both  signs  and  symptoms  of  dry  eye  syndrome  with  0.1%  RGN-259  versus
placebo, while showing excellent safety, comfort, and tolerability profiles. The ocular discomfort symptom showed a statistically significant reduction in the
RGN-259-treated group at day 15 as compared to placebo (p=0.0149) in the change from baseline. For sign, RGN-259 also improved the dry eye patient’s
ability to withstand an exacerbated condition in a patient subgroup with both compromised corneal fluorescein staining and Schirmer’s test at baseline. In this
population, RGN-259 showed superiority over placebo in reducing corneal fluorescein staining in the change from baseline at days 15 and 29 (p=0.0207 and
0.0254, respectively). RGN-259 confirmed its global effects on dry eye syndrome and fast onset in multiple sign and symptom efficacies with no safety issues
in the ARISE-1 and ARISE-2 studies as well as in the pooled data, although ARISE-2 was not successful in duplicating the results of ARISE-1 where the
study population was limited and less diversified. ReGenTree is proceeding with its RGN-259 development plan as discussed with the FDA in April 2018.
Most recently, ReGenTree reaffirmed that the manufacturing of the investigational product for ARISE-3 has been completed and the protocol for the study
has been finalized. ReGenTree entered into a management agreement for ARISE-3 with Ora, Inc. and the study was recently initiated with the first patient
anticipated to be enrolled in the second quarter of 2019.

The NK trial (SEER-1), a smaller study in an orphan population, has enrolled seventeen patients thus far, and has several additional patients being
screened,  with  a  goal  of  forty-six.  ReGenTree  has  expanded  its  efforts  to  accelerate  patient  enrollment  by  offering  incentives  to  each  study  site  based  on
numbers of enrollees as well as payments to referral sites. In 2018, ReGenTree disclosed that 7 of 17 patients enrolled SEER-1 have completely healed. To
participate in the trial the patients were required to have a persistent epithelial defect (non-healing corneal wound). While these preliminary observations are
encouraging, it should be noted that the patients and treating physicians remain masked while the trial is on-going, so it is not known whether the healed
patients are in the RGN-259 group, placebo group, or distributed among both. It is not known when this study will be completed.

GtreeBNT has developed the CMC (chemistry, manufacturing and controls) dossier required for Phase 3 clinical trials and commercialization in the
U.S.  and  in  Korea.  This  comprehensive  and  critical  effort  ensures  that  final  drug  product  manufacturing,  packaging,  stability,  purity,  reproducibility,  etc.,
meets  regulatory  guidelines  and  product  specifications.  The  product  of  this  activity  is  the  current  product  format  being  utilized  in  the  U.S.  trials  being
conducted by ReGenTree and will also be utilized in the planned clinical activity to be conducted by GtreeBNT under the RGN-259 license agreement for
Pan Asia.

27

 
 
 
 
 
 
 
 
 
 
In February 2017, our licensee for RGN-137, GtreeBNT, received permission from the U.S. FDA to sponsor a Phase 3 clinical trial using RGN-137
to treat patients with epidermolysis bullosa (EB), a genetic disease that causes severe blistering of the skin and internal organs. In August 2017, the Company
amended  the  License  Agreement  for  RGN-137  held  by  GtreeBNT.  Under  the  amendment  the  Territory  was  expanded  to  include  Europe,  Canada,  South
Korea,  Australia  and  Japan.  GtreeBNT  initiated  a  small  open  trial  in  patients  with  EB  in  December  2018  to  evaluate  RGN-137  in  such  patients  prior  to
sponsoring a larger Phase 3 trial.

Currently,  we  have  active  partnerships  in  four  major  territories:  North  America,  Europe,  China  and  Pan  Asia.  Our  partners  have  been  moving
forward  and  making  progress  in  each  territory.  In  each  case,  the  cost  of  development  is  being  borne  by  our  partners  with  no  financial  obligation  for
RegeneRx. We still have significant clinical assets to develop, primarily RGN-352 (injectable formulation of Tß4 for cardiac and CNS disorders) in the U.S.,
most of Asia, and Europe; RGN-259 in the EU. In August 2017 we amended the RGN-137 License Agreement with GtreeBNT, expanding the territory to
include Europe, Canada, South Korea, Australia and Japan. Regarding RGN-259, our goal is to wait until satisfactory results are obtained from the current
ophthalmic clinical program in the U.S. before moving into the EU. This should allow us to obtain a higher value for the asset at that time. However, we
intend  to  continue  to  develop  RGN-352,  our  injectable  systemic  product  candidate  for  cardiac  and  central  nervous  system  indications,  either  by  obtaining
grants to fund a Phase 2a clinical trial in the cardiovascular or central nervous system fields or finding a suitable partner with the resources and capabilities to
develop it as we have with RGN-259.

Financial Operations Overview

We  have  never  generated  product  revenues,  and  we  do  not  expect  to  generate  product  revenues  until  the  FDA  approves  one  of  our  product
candidates,  if  ever,  and  we  begin  marketing  and  selling  it.  We  anticipate  incurring  additional  operating  losses  in  the  future  as  we  continue  to  explore  the
potential clinical benefits of Tß4-based product candidates over multiple indications. To fund further development and clinical trials we have entered into a
series of strategic partnerships under licensing and joint venture agreements (see Note 4 of our financial statements) where our partners are responsible for
advancing development of our product candidates with multiple clinical trials.

On February 27, 2019 we sold a series of convertible promissory notes to management, the Board of Directors, and accredited investors, including
Essetifin S.p.A., our largest shareholder. The sale of the notes will result in gross proceeds to the Company of $1,300,000 over two closings. The first closing
in the amount of $650,000 occurred on February 27th and the second closing, also in the amount of $650,000 will occur within three days of the Company
providing notice of the enrolment of the first patent in the ARISE-3 clinical trial in DES sponsored by ReGenTree. ReGenTree has informed us that they now
expect the ARISE-3 clinical trial to occur in the second quarter of 2019. At present, with the receipt of the sale proceeds from the first closing coupled with
the anticipated proceeds from the second closing, we will have sufficient cash to fund planned operations through the first quarter of 2020. We will need
additional  funds  to  continue  operations  significantly  beyond  the  first  quarter  of  2020  and  will  require  substantial  capital  if  we  wish  to  internally  advance
development  of  our  unlicensed  programs.  Accordingly,  we  will  continue  to  evaluate  opportunities  to  raise  additional  capital  and  are  in  the  process  of
exploring  various  alternatives,  including,  without  limitation,  a  public  or  private  placement  of  our  securities,  debt  financing,  corporate  collaboration  and
licensing arrangements, government grants, or the sale of our company or certain of our intellectual property rights.

Most of our expenditures to date have been for research and development, or R&D, activities and general and administrative, or G&A, activities.
R&D costs include all of the wholly-allocable costs associated with our various clinical programs passed through to us by our outsourced vendors. Those
costs  include  manufacturing  Tß4  and  peptide  fragments,  formulation  of  Tß4  into  our  product  candidates,  stability  studies  for  both  Tß4,  and  the  various
formulations, preclinical toxicology, safety and pharmacokinetic studies, clinical trial management, medical oversight, laboratory evaluations, statistical data
analysis, regulatory compliance, quality assurance and other related activities. R&D includes cash and non-cash compensation, travel and other miscellaneous
costs of our internal staff and our independent contractors who focus primarily on management of R&D related activities. R&D also includes a proration of
our common infrastructure costs for office space and communications. We expense our R&D costs as they are incurred.

R&D expenditures are subject to the risks and uncertainties associated with clinical trials and the FDA review and approval process. As a result,
these expenses could exceed our expectations, possibly materially. We are uncertain as to what we will incur in future research and development costs for our
clinical  studies,  as  these  amounts  are  subject  to  the  outcome  of  current  studies,  management's  continuing  assessment  of  the  economics  of  each  individual
research and development project and the internal competition for project funding.

28

 
 
 
 
 
 
 
 
 
G&A costs include outside professional fees for legal, business development, audit and accounting services. G&A also includes cash and non-cash
compensation,  travel  and  other  miscellaneous  costs  of  our  internal  G&A  personnel,  two  in  total,  who  are  wholly  dedicated  to  G&A  efforts.  G&A  also
includes  a  proration  of  our  common  infrastructure  costs  for  office  space,  and  communications.  Our  G&A  expenses  also  include  costs  to  maintain  our
intellectual property portfolio. Historically we have expanded our patent prosecution activities and in some cases, we have filed patent applications for non-
critical strategic purposes intended to prevent others from filing similar patent claims. We continue to closely monitor our patent applications in the United
States, Europe and other countries with the advice of outside legal counsel to determine if they will continue to provide strategic benefits. In cases where we
believe the benefit has been realized or it becomes unnecessary due to the issuance of other patents, or for other reasons that will not affect the strength of our
intellectual  property  portfolio,  we  have  and  will  continue  to  abandon  these  patent  applications  in  order  to  reduce  our  costs  of  continued  prosecution  or
maintenance.

Critical Accounting Policies

We prepare our financial statements in conformity with accounting principles generally accepted in the United States. Such accounting principles
require  that  our  management  make  estimates  and  assumptions  that  affect  the  amounts  reported  in  our  financial  statements  and  accompanying  notes.  Our
actual  results  could  differ  materially  from  those  estimates.  The  items  in  our  financial  statements  that  have  required  us  to  make  significant  estimates  and
judgments are as follows:

Revenue Recognition

Subsequent to the adoption of Accounting Standards Codification Revenue from Contracts with Customers (“ASC 606”) on January 1, 2018

The  Company  analyzes  contracts  to  determine  the  appropriate  revenue  recognition  using  the  following  steps:  (i)  identification  of  contracts  with
customers, (ii) identification of distinct performance obligations in the contract, (iii) determination of contract transaction price, (iv) allocation of contract
transaction price to the performance obligations and (v) determination of revenue recognition based on timing of satisfaction of the performance obligation.
The  Company  recognizes  revenues  upon  the  satisfaction  of  its  performance  obligation  (upon  transfer  of  control  of  promised  goods  or  services  to  our
customers) in an amount that reflects the consideration to which it expects to be entitled to in exchange for those goods or services. Whenever we determine
that an arrangement should be accounted for as a single unit of accounting, we must determine the period over which the performance obligations will be
performed, and revenue will be recognized. Revenue will be recognized using either a relative performance or straight-line method. We recognize revenue
using the relative performance method provided that we can reasonably estimate the level of effort required to complete our performance obligations under an
arrangement and such performance obligations are provided on a best-efforts basis. Revenue recognized is limited to the lesser of the cumulative amount of
payments received or the cumulative amount of revenue earned, as determined using the relative performance method, as of each reporting period.

The Company’s contracts with customers may at times include multiple promises to transfer products and services. Contracts with multiple promises
are analyzed to determine whether the promises, which may include a license together with performance obligations such as providing a clinical supply of
product and steering committee services, are distinct and should be accounted for as separate performance obligations or whether they must be accounted for
as  a  single  performance  obligation.  The  Company  accounts  for  individual  performance  obligations  separately  if  they  are  distinct.  Determining  whether
products  and  services  are  considered  distinct  performance  obligations  may  require  significant  judgment.  If  we  cannot  reasonably  estimate  when  our
performance  obligation  either  ceases  or  becomes  inconsequential  and  perfunctory,  then  revenue  is  deferred  until  we  can  reasonably  estimate  when  the
performance obligation ceases or becomes inconsequential. Revenue is then recognized over the remaining estimated period of performance.

Whenever  the  Company  determines  that  an  arrangement  should  be  accounted  for  as  a  combined  performance  obligation,  we  must  determine  the
period  over  which  the  performance  obligation  will  be  performed  and  when  revenue  will  be  recognized.  Revenue  is  recognized  using  either  a  relative
performance or straight-line method. We recognize revenue using the relative performance method provided that the we can reasonably estimate the level of
effort required to complete our performance obligation under an arrangement and such performance obligation is provided on a best-efforts basis. Revenue
recognized  is  limited  to  the  lesser  of  the  cumulative  amount  of  payments  received  or  the  cumulative  amount  of  revenue  earned,  as  determined  using  the
relative performance method, as of each reporting period.

If  the  Company  cannot  reasonably  estimate  the  level  of  effort  required  to  complete  our  performance  obligation  under  an  arrangement,  the
performance  obligation  is  provided  on  a  best-efforts  basis  and  we  can  reasonably  estimate  when  the  performance  obligation  ceases  or  the  remaining
obligations  become  inconsequential  and  perfunctory,  then  the  total  payments  under  the  arrangement,  excluding  royalties  and  payments  contingent  upon
achievement  of  substantive  milestones,  would  be  recognized  as  revenue  on  a  straight-line  basis  over  the  period  we  expect  to  complete  our  performance
obligations. Revenue is limited to the lesser of the cumulative amount of payments received or the cumulative amount of revenue earned, as determined using
the straight-line basis, as of the period ending date.

29

 
 
 
 
 
 
 
 
 
 
 
If the Company cannot reasonably estimate when our performance obligation either ceases or becomes inconsequential and perfunctory, revenue is
deferred  until  we  can  reasonably  estimate  when  the  performance  obligation  ceases  or  becomes  inconsequential.  Revenue  is  then  recognized  over  the
remaining estimated period of performance.

At  the  inception  of  each  arrangement  that  includes  development  milestone  payments,  the  Company  evaluates  the  probability  of  reaching  the
milestones and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue
reversal would not occur in the future, the associated milestone value is included in the transaction price. Milestone payments that are not within the control
of the Company or the licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received and therefore
revenue recognized is constrained as management is unable to assert that a reversal of revenue would not be possible. The transaction price is then allocated
to  each  performance  obligation  on  a  relative  standalone  selling  price  basis,  for  which  the  Company  recognizes  revenue  as  or  when  the  performance
obligations under the contract are satisfied. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of such
development milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded
on a cumulative catch-up basis, which would affect revenues and earnings in the period of adjustment.

Amounts  received  prior  to  satisfying  the  above  revenue  recognition  criteria  are  recorded  as  unearned  revenue  in  our  accompanying  condensed

balance sheets.

Contract assets are generated when contractual billing schedules differ from revenue recognition timing. Contract assets represent a conditional right
to consideration for satisfied performance obligations that becomes a billed receivable when the conditions are satisfied. There were no contract assets as of
December 31, 2018.

Contract liabilities result from arrangements where we have received payment in advance of performance under the contract. Changes in contract

liabilities are generally due to either receipt of additional advance payments or our performance under the contract.

We have the following amounts recorded for contract liabilities:

Unearned revenue

  $

2,254,848    $

2,124,515 

  December 31, 2018    December 31, 2017 

The contract liabilities amount disclosed above as of December 31, 2018, is primarily related to revenue being recognized on a straight-line basis
over periods ranging from 23 to 30 years, which, in management’s judgment, is the best measure of progress towards satisfying the performance obligations
and represents the Company’s best estimate of the period of the obligation.

Variable Interest Entities

We have determined that the Joint Venture is a “variable interest entity”, since the total equity investment at risk is not sufficient to permit the Joint
Venture to finance its activities without additional subordinated financial support. Further, because of GtreeBNT’s majority equity stake in the Joint Venture,
voting control, control of the board of directors, and substantive management rights, and given that we do not have the power to direct the Joint Venture’s
activities that most significantly impact its economic performance, we have determined that it is not the primary beneficiary of the Joint Venture and therefore
is not required to consolidate the Joint Venture. We report its equity stake in the Joint Venture using the equity method of accounting because, while it does
not control the Joint Venture, we can exert significant influence over the Joint Ventures activities by virtue of its board representation.

Because we are not obligated to fund the Joint Venture, and have not provided any financial support, and have no commitment to provide financial
support in the future to the Joint Venture, the carrying value of its investment in the Joint Venture is zero at both December 31, 2018 and 2017. As a result, we
are not recognizing our share of the Joint Venture’s operating losses and will not recognize any such losses until the Joint Venture produces net income (as
opposed to net losses) and at that point we will reduce our share of the Joint Venture’s net income by our share of previously suspended net losses. As of
December 31, 2018, because we have not provided any financial support, we have no financial exposure as a result of its variable interest in the Joint Venture.

Convertible Notes with Detachable Warrants.

In accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 470-20, Debt with Conversion
and Other Options, the proceeds received from convertible notes are allocated to the instruments based on the relative fair values of the convertible notes
without the warrants and of the warrants themselves at the time of issuance. The portion of the proceeds allocated to the warrants is recognized as additional
paid-in capital and a debt discount. The debt discount related to warrants is accreted into interest expense through maturity of the notes.

Derivative Financial Instruments.

Derivative  financial  instruments  consist  of  financial  instruments  or  other  contracts  that  contain  a  notional  amount  and  one  or  more  underlying
variables  (e.g.,  interest  rate,  security  price  or  other  variable),  which  require  no  initial  net  investment  and  permit  net  settlement.  Derivative  financial
instruments  may  be  free-standing  or  embedded  in  other  financial  instruments.  Further,  derivative  financial  instruments  are  initially,  and  subsequently,
measured at fair value and recorded as liabilities or, in rare instances, assets.

We do not use derivative financial instruments to hedge exposures to cash-flow, market or foreign-currency risks. However, we have issued financial
instruments including warrants that are either (i) not afforded equity classification, (ii) embody risks not clearly and closely related to host contracts, or (iii)
may  be  net-cash  settled  by  the  counterparty.  In  certain  instances,  these  instruments  are  required  to  be  carried  as  derivative  liabilities,  at  fair  value,  in  our
financial statements. In other instances these instruments are classified as equity instruments in our financial statements.

We estimate the fair values of its derivative financial instrument using the Black-Scholes option pricing model and in certain instances have used a
custom Monte Carlo model where appropriate as these models embody all of the requisite assumptions (including trading volatility, estimated terms and risk-
free  rates)  necessary  to  fair  value  these  instruments.  Estimating  fair  values  of  derivative  financial  instruments  requires  the  development  of  significant  and
subjective estimates that may, and are likely to, change over the duration of the instrument with related changes in internal and external market factors. In
addition, option-based techniques are highly volatile and sensitive to changes in the trading market price of our common stock, which has a high-historical
volatility. Since derivative financial instruments are initially and subsequently carried at fair values, our operating results reflect the volatility in these estimate
and assumption changes in each reporting period.

Upon the adoption of new accounting guidance on January 1, 2018, the embedded conversion features in the Company’s convertible notes are no

longer accounted for as derivative liabilities.

Share-based payment

We account for share-based compensation based on the estimated grant date fair value of the award using the Black-Scholes option-pricing model.

The estimated grant date fair value is recognized over the requisite service period.

Determining the appropriate fair value model and calculating the fair value of share-based payment awards require the input of highly subjective
assumptions, including the expected life of the share-based payment awards and stock price volatility. Since our historical data is limited, the expected life
was  determined  in  accordance  with  SEC  Staff  Accounting  Bulletin  No.  107  guidance  for  “plain  vanilla”  options.  Since  our  historical  trading  volume  is
relatively low, we estimated the expected volatility based on monthly closing prices for a period consistent with the expected life of the option.

The  assumptions  used  in  calculating  the  fair  value  of  share-based  payment  awards  represent  management’s  best  estimates,  but  these  estimates
involve inherent uncertainties and the application of management judgment. As a result, if factors change and we use different assumptions, our stock-based
compensation  expense  could  be  materially  different  in  the  future.  See  Notes  2  and  8  to  the  Financial  Statements  for  a  further  discussion  on  stock-based
compensation and the relative ranges of our historical, underlying assumptions.

Results of Operations

Comparison of years ended December 31, 2018 and 2017

Revenues. For the year ended December 31, 2018, we recorded revenue in the amount of approximately $70,000 versus $57,000 recorded for the
year ended December 31, 2017. The 2018 revenue reflects the amortization over 30 years of the payments we received under the original joint venture license
agreement and the payment we received for the expansion of the territorial rights to include Canada in April 2016. The payments received under the 2017
RGN-137 license amendment were amortized for revenue over 23 years. There were additional payments received pursuant to the license amendment during
2018 and 2017 which resulted in an increase in revenue recognized.

Expenses — Research and development. For the year ended December 31, 2018, our R&D expenditures decreased by $63,000, or 44%, to $81,000,
from approximately $144,000 in 2017. The decrease reflects a further shift of our internal R&D efforts as our partners assume full responsibility for clinical
development and is characterized by decreases in R&D consulting (decrease of $52,000), stock option expense (decrease of $4,000) and internal allocations
and  other  (decrease  of  $7,000)  versus  the  prior  year.  We  expect  our  R&D  expenses  will  remain  at  low  levels  unless  we  decide  to  reinitiate  internal  R&D
efforts for our unpartnered programs.

Expenses — General and administrative. For the year ended December 31, 2018, our G&A expenses decreased by approximately $45,000, or 3%, to
$1,312,000  from  $1,357,000  in  2017.  Decreases  are  reflected  in  2018  expenses  for  salaries  (decrease  of  $54,000),  insurance  (decrease  of  $13,000),
sponsorship (decrease of $10,000), travel (decrease of $12,000) and investor relations (decrease of $2,000) which were offset by increases in stock option
expense  (increase  of  $9,000),  non-income  based  tax  expense  (increase  of  $33,000)  and  professional  fees  (increase  of  $4,000).  We  believe  that  our  G&A
expenses  will  remain  at  current  levels  as  we  wait  for  data  from  the  upcoming  clinical  trials  being  conducted  by  our  partners.  If  we  enter  into  additional
partnerships or other business transactions, including financings, we will incur additional legal and transaction related expenses.

Expenses - Provision for income tax. For the year ended December 31, 2018, our Statement of Operations does not reflect income tax expense versus
$99,000 reflected in the year ended December 31, 2017. The 2017 expense relates to the recording of a deferred tax credit resulting from the withholding of
certain amounts from the initial payment received under the RGN-137 License Agreement amendment. The withholding is mandated under a United States of
America and The Republic of Korea Tax treaty entered into in 1976.

Net  Loss/Income.  Our  Statement  of  Operations  reflects  a  net  loss  of  $1,993,553  for  the  year  ended  December  31,  2018  versus  net  income  of
$286,487 for the year ended December 31, 2017. The 2018 net loss reflects inducement expense of $582,904 related to the new warrant component of the
March 2018 warrant reprice and exercise agreement (see Note 8). The 2017 period reflects the change in the value of the conversion feature related to the
derivative liability related to our convertible debt as well as the reduction of the value of the investor rights associated with the 2016 Offering. The value of
this conversion feature was indexed to the share price of our common stock and decreased as our share price decreased. The share price of our common stock
decreased from $0.32 on December 31, 2016 to $0.17 on December 31, 2017, which resulted in a decrease in the fair value of our convertible debt derivative
component of $1,761,668 which combined with an unrealized gain related to the investor rights associated with the 2016 Offering which lapsed in the August
2017 in the amount $238,937 and resulted in the recording of a change in fair value of derivative liabilities of $2,000,605. Losses from operations decreased
in 2018 versus 2017, $1,323,369 and $1,444,630, respectively.

Liquidity and Capital Resources

We  have  not  commercialized  any  of  our  product  candidates  to  date  and  have  incurred  significant  losses  since  inception.  In  addition,  we  have
primarily  financed  our  operations  through  the  equity  or  issuance  of  debt  including  the  sale  of  a  series  of  convertible  promissory  notes  through  private
placements  with  accredited  investors  and  the  March  and  August  2014  private  placements  of  common  stock  with  GtreeBNT  as  well  as  our  entry  into  the
ReGenTree joint venture in early 2015. The report of our independent registered public accounting firm regarding our financial statements for the year ended
December  31,  2018  contains  an  explanatory  paragraph  regarding  the  uncertainty  of  our  ability  to  continue  as  a  going  concern  based  upon  our  history  of
operating losses and dependence on future financing in order to meet our planned operating activities.

Our Statement of Operations reflects a net loss of $1,993,553 for the year ended December 31, 2018. We had cash and cash equivalents of $237,261
at  December  31,  2018.  On  February  27,  2019,  we  sold  a  series  of  convertible  promissory  notes  to  management,  the  Board  of  Directors,  and  accredited
investors,  including  Essetifin  S.p.A.,  our  largest  shareholder.  The  sale  of  the  notes  will  result  in  gross  proceeds  to  the  Company  of  $1,300,000  over  two
closings. The first closing in the amount of $650,000 occurred on February 27, 2019 and the second closing, also in the amount of $650,000 will occur within
three days of the Company providing notice of the enrolment of the first patent in the ARISE-3 clinical trial in DES sponsored by ReGenTree. ReGenTree has
informed us that they now expect the ARISE-3 clinical trial to occur in the second quarter of 2019. At present, with the receipt of the sale proceeds from the
first closing coupled with the anticipated proceeds from the second closing, we will have sufficient cash to fund planned operations through the first quarter of
2020.

We may also receive funds from grants, new partnerships or the raising of additional capital if the market climate warrants. Additionally, we intend
to  continue  to  pursue  additional  partnering  activities,  particularly  for  RGN-352,  our  injectable  systemic  product  candidate  for  cardiac  and  central  nervous
system indications. This estimate also does not include receipt of any funds from grants, new partnerships or the raising of additional capital if the market
climate warrants. A sale of common stock and warrants, a convertible instrument or additional partnering of licensed rights are possible sources of operating
capital in the future. Additionally, we intend to continue to pursue additional partnering activities, particularly for RGN-352, our injectable systemic product
candidate for cardiac and central nervous system indications.

Net Cash Used in Operating Activities. Net cash used in operating activities was $888,000 and $663,000 for the years ended December 31, 2018
and 2017, respectively. In 2018, our statement of cash flows reflects a net inflow of $130,000 related to payments received under license agreements versus
$543,000 from the same source in 2017.

Net Cash Used in Investing Activities. We did not use any cash for investing activities in 2018 or 2017.

Net  Cash  Provided  by  Financing  Activities.  Net  cash  provided  by  financing  activities  totaled  $944,000  and  $75,000  for  the  years  ended
December 31, 2018 and 2017, respectively. In 2018, the cash provided by financing activities consisted of the proceeds from the warrant reprice transaction in
March 2018 while the 2017 cash provided by financing activities was a result of the exercise of stock options and warrants.

Future Funding Requirements

The expenditures that will be necessary to execute our business plan are subject to numerous uncertainties that may adversely affect our liquidity and
capital  resources.  Currently,  RegeneRx  has  active  partnerships  in  three  major  territories:  the  U.S.,  China  and  Pan  Asia.  Our  partners  have  been  moving
forward  and  making  progress  in  each  territory.  In  each  case,  the  cost  of  development  is  being  borne  by  our  partners  with  no  financial  obligation  for
RegeneRx. Patient accrual, treatment, and follow-up for ophthalmic trials are, in general, relatively fast, as opposed to most other clinical efforts, top line data
from the U.S. dry eye trial was released in October 2017 and data from the NK study in 2019 or possibly later.

We still have significant clinical assets to develop, primarily RGN-352 (injectable formulation of Tß4 for cardiac and CNS disorders) in the U.S.,
Pan Asia, and Europe, and RGN-259 in the EU. Our goal is to wait until the results are obtained from the current ophthalmic clinical trials before moving into
the EU with RGN-259. If successful, this should allow us to obtain a higher value for the asset at that time. However, we intend to continue to develop RGN-
352, either by obtaining grants to fund a Phase 2a clinical trial in the cardiovascular or central nervous system fields or finding a suitable partner with the
resources and capabilities to develop it as we have with RGN-259.

In addition, the length of time required for clinical trials varies substantially according to the type, complexity, novelty and intended use of a product

candidate. Some of the factors that could impact our liquidity and capital needs include, but are not limited to:

·
·
·
·
·
·

·
·
·

the progress of our clinical trials;
the progress of our research activities;
the number and scope of our research programs;
the progress of our preclinical development activities;
the costs involved in preparing, filing, prosecuting, maintaining, enforcing and defending patent and other intellectual property claims;
the costs related to development and manufacture of preclinical, clinical and validation lots for regulatory purposes and commercialization of
drug supply associated with our product candidates;
our ability to enter into corporate collaborations and the terms and success of these collaborations;
the costs and timing of regulatory approvals; and
the costs of establishing manufacturing, sales and distribution capabilities.

Moreover,  the  duration  and  the  cost  of  clinical  trials  may  vary  significantly  over  the  life  of  a  project  as  a  result  of  differences  arising  during  the

clinical trial protocol, including, among others, the following:

·
·
·
·

the number of patients that ultimately participate in the trial;
the duration of patient follow-up that seems appropriate in view of the results;
the number of clinical sites included in the trials; and
the length of time required to enroll suitable patient subjects.

Also,  we  test  our  product  candidates  in  numerous  preclinical  studies  to  identify  indications  for  which  they  may  be  efficacious.  We  may  conduct
multiple clinical trials to cover a variety of indications for each product candidate. As we obtain results from trials, we may elect to discontinue clinical trials
for certain product candidates or for certain indications in order to focus our resources on more promising product candidates or indications.

Our  proprietary  product  candidates  have  not  yet  achieved  FDA  regulatory  approval,  which  is  required  before  we  can  market  them  as  therapeutic
products. In order to proceed to subsequent clinical trial stages and to ultimately achieve regulatory approval, the FDA must conclude that our clinical data
establish safety and efficacy. Historically, the results from preclinical studies and early clinical trials have often not been predictive of results obtained in later
clinical trials. A number of new drugs and biologics have shown promising results in clinical trials, but subsequently failed to establish sufficient safety and
efficacy data to obtain necessary regulatory approvals.

In  February  2017,  we  amended  our  office  lease  agreement  and  the  term  was  extended  through  July  2020.  During  the  extended  term  our  rental

payments will average approximately $4,000 per month.

Sources of Liquidity

We  have  not  commercialized  any  of  our  product  candidates  to  date  and  have  primarily  financed  our  operations  through  the  issuance  of  common
stock and common stock warrants in private and public financings in addition to a series of five convertible debt placements from October 2012 to January
2014. In June of 2016, we raised $1,520,000 by selling 5,147,059 shares of common stock and warrants to purchase 5,147,059 shares of common stock to
Sabby.  On  March  2,  2018,  we  entered  into  a  warrant  reprice  and  exercise  and  issuance  agreement  with  Sabby,  which,  in  consideration  of  the  holders
exercising in full all of the 2016 Offering warrants the exercise price per share of the warrants was reduced to $0.20 per share. In addition, and as further
consideration, we issued to the holders of the 2016 Offering warrants 3,860,294 new warrants with an exercise price of $0.2301 per share. Pursuant to the
terms of the Reprice Agreement the exercise price of the new warrants will be reduced from $0.2301 to $0.125 as a result of the March 2019 note sale. We
received gross proceeds of approximately $1,000,000 pursuant the exercise and issued 5,147,059 of common stock. In August 2017, we amended the RGN-
137 License Agreement with GtreeBNT in exchange for a series of payments, the last of which will be received in June 2018. Most recently, on February 27,
2019, we sold a series of convertible promissory notes to accredited investors including Essetifin S.p.A., our largest shareholder. The sale of the notes will
result in gross proceeds to the Company of $1,300,000 over two closings. The first closing in the amount of $650,000 occurred on February 27th  and  the
second  closing,  also  in  the  amount  of  $650,000  will  occur  within  three  days  of  the  Company  providing  notice  of  the  enrolment  of  the  first  patent  in  the
ARISE-3 clinical trial in DES sponsored by ReGenTree. ReGenTree has informed us that they now expect the ARISE-3 clinical trial to occur in the second
quarter  of  2019.  The  notes  contain  a  $0.12  conversion  price  and  are  initially  convertible  into  10,833,333  shares  of  common  stock.  The  purchasers  also
received a warrant exercisable at $0.18 to purchase additional 8,125,000 shares of common stock. At present, with the receipt of the sale proceeds from the
first closing coupled with the anticipated proceeds from the second closing, we will have sufficient cash to fund planned operations through the first quarter of
2020.

We continuously monitor our cash use as well as the clinical timelines. We continue to evaluate options including the licensing of additional rights to

commercialize our clinical products as well as raising capital through the capital markets.

We  have  various  strategic  agreements  and  license  agreements  with:  GtreeBNT,  ReGenTree  and  Lee’s.  These  license  agreements  provide  for  the
opportunity for us to receive milestone payments upon specified commercial events and royalty payments in connection with any commercial sales of the
licensed products in the respective territories. However, there are no assurances that we will be able to attain any such milestones or generate any such royalty
payments under the agreements.

Licensing Agreements

As noted above, we have entered into two strategic agreements with GtreeBNT. GtreeBNT licensed the development and commercialization rights
for RGN-259, in Asia (excluding China, Hong Kong, Macau and Taiwan) while also licensing the development and commercialization rights for RGN-137 in
the U.S. In August 2017, the Company amended the License Agreement for RGN-137 held by GtreeBNT. Under the amendment the Territory was expanded
to include Europe, Canada, South Korea, Australia and Japan. In January 2015, we entered into a joint venture and licensing agreement with GtreeBNT that
will  commercialize  RGN-259  for  treatment  of  dry  eye  and  neurotrophic  keratitis  in  the  United  States,  as  well  as  any  other  indications  within  the  field  of
ophthalmology.  The  license  agreements  provide  for  the  opportunity  for  us  to  receive  milestone  payments  upon  specified  commercial  events  and  royalty
payments in connection with any commercial sales of the licensed products in the respective territories. However, there are no assurances that we will be able
to attain any such milestones or generate any such royalty payments under the agreements.

We also have entered into a license agreement with Lee’s Pharmaceuticals that provides for the opportunity for us to receive milestone payments
upon  specified  events  and  royalty  payments  in  connection  with  any  commercial  sales  of  Tß4-based  products  in  China,  Hong  Kong,  Macau  and  Taiwan.
However, there are no assurances that we will be able to attain any such milestones or generate any such royalty payments under the agreement. In February
2019, the License Agreement was amended and assigned by Lee’s to their affiliate, Zhaoke Ophthalmology Pharmaceutical Limited. There are no economic
changes to the License Agreement.

Government Grants

We have pursued, and may continue to pursue, government funding for both RGN-259 and RGN-352. We are not currently receiving funding under a

Government Grant.

Other Financing Sources

Other potential sources of outside capital include entering into additional strategic business relationships, additional issuances of equity securities or
debt financing or other similar financial instruments. If we raise additional capital through a strategic business relationship, we may have to give up valuable
rights to our intellectual property. If we raise funds by selling additional shares of our common stock or securities convertible into our common stock, the
ownership interest of our existing stockholders may be significantly diluted. In addition, if additional funds are raised through the issuance of preferred stock
or debt securities, these securities are likely to have rights, preferences and privileges senior to our common stock and may involve significant fees, interest
expense, restrictive covenants and the granting of security interests in our assets.

34

 
 
 
 
 
 
 
 
 
 
 
 
 
Our  failure  to  successfully  address  liquidity  requirements  could  have  a  materially  negative  impact  on  our  business,  including  the  possibility  of
surrendering our rights to some technologies or product opportunities, delaying our clinical trials, or ceasing operations. There can be no assurance that we
will be able to obtain additional capital in sufficient amounts, on acceptable terms, or at all.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, as such term is defined in Item 303(a)(4) of Regulation S-K.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Not applicable.

Item 8. Financial Statements and Supplementary Data.

The financial statements required by this item are included beginning on page F-1 of this report.

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

None.

Item 9A. Controls and Procedures.

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in reports that we file or
submit  under  the  Exchange  Act  is  recorded,  processed,  summarized  and  timely  reported  as  provided  in  SEC  rules  and  forms  and  that  such  information  is
accumulated and communicated to our management, including our Chief Executive Officer who currently serves as both our principal executive officer and
our principal financial officer, as appropriate, to allow for timely decisions regarding required disclosure. We periodically review the design and effectiveness
of our disclosure controls and procedures, including compliance with various laws and regulations that apply to our operations. We make modifications to
improve the design and effectiveness of our disclosure controls and procedures and may take other corrective action if our reviews identify a need for such
modifications or actions. In designing and evaluating the disclosure controls and procedures, we recognize that any controls and procedures, no matter how
well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and we apply judgment in evaluating the cost-
benefit relationship of possible controls and procedures. In addition, the design of any system of controls also is based in part upon certain assumptions about
the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions;
over  time,  controls  may  become  inadequate  because  of  changes  in  conditions,  or  the  degree  of  compliance  with  policies  or  procedures  may  deteriorate.
Because of the inherent limitations in a control system, misstatements due to error or fraud may occur and not be detected.

We have carried out an evaluation, under the supervision and the participation of our management, including our Chief Executive Officer, of the
effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act), as
of  December  31,  2018  the  end  of  the  period  covered  by  this  report.  Based  upon  that  evaluation,  our  Chief  Executive  Officer,  in  his  capacity  as  principal
executive officer and principal financial officer, concluded that our disclosure controls and procedures were effective as of December 31, 2018.

Management’s Annual Report on Internal Control over Financial Reporting

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting,  as  such  term  is  defined  in
Exchange Act Rules 13a-15(f) and 15d-15(f). Internal control over financial reporting is a process designed to provide reasonable assurance regarding the
reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with  U.S.  generally  accepted  accounting
principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in
reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the  company;  (ii)  provide  reasonable  assurance  that
transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance  with  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
(iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could
have a material effect on our financial statements.

Because of its inherent limitations, including the possibility of human error and the circumvention or overriding of controls, a system of internal
control  over  financial  reporting  can  provide  only  reasonable  assurance  and  may  not  prevent  or  detect  all  misstatements.  Therefore,  even  those  systems
determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Further, because of changes
in conditions, effectiveness of internal control over financial reporting may vary over time.

35

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
A significant deficiency is a control deficiency, or combination of control deficiencies, in internal control over financial reporting that is less severe
than  a  material  weakness,  yet  important  enough  to  merit  attention  by  those  responsible  for  oversight  of  the  company’s  financial  reporting.  A  material
weakness is a deficiency, or combination of control deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a
material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis.

Under the supervision and with the participation of our management, including our Chief Executive Officer in his capacity as principal executive
officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework

high-level  management  experience  necessary  to  oversee  and  direct  our  business.  To  that  end,  our  board  intends  to  maintain  membership  of  directors  who
complement and strengthen the skills of other members and who also exhibit integrity, collegiality, sound business judgment and other qualities that we view
as  critical  to  effective  functioning  of  the  board.  The  brief  biographies  below  include  information,  as  of  the  date  of  this  report,  regarding  the  specific  and
particular experience, qualifications, attributes or skills of each director or nominee that led the board to believe that the director should serve on the board.

six years, all of which are non-profit entities that support bioscience development and education in the State of Maryland. Mr. Finkelstein received a business
degree in finance from the University of Texas. The Board believes that Mr. Finkelstein’s history and long tenure as our Chief Executive Officer positions him

prior companies has provided him with operational and industry expertise, as well as leadership skills that are important to the Board.

Dr.  Goldstein  has  served  as  the  Chairman  of  our  Board  of  Directors  and  our  Chief  Scientific  Officer  since  he  founded  our  company  in  1982.

financial matters.

Mr. Bove has served as a member of our Board of Directors since 2004 and has more than 30 years of business and management experience within
the  pharmaceutical  industry.  Mr.  Bove  is  currently  based  in  Hong  Kong  and  in  Europe,  serving  as  a  consultant  to  emerging  pharmaceutical  companies

company of Sigma-Tau Group, a leading international pharmaceutical company (Sigma-Tau Finanziaria S.p.A. - now Essetifin S.p.a. - and its affiliates are
collectively  our  largest  stockholder).  Mr.  Bove,  who  resigned  this  role  with  Sigma-Tau  on  March  31,  2014,  has  also  held  a  number  of  senior  positions  in
business, licensing and corporate development within Sigma-Tau Group. Mr. Bove obtained his law degree at the University of Parma, Italy, in 1980. In 1985,
he attended the Academy of American and International Laws at the International and Comparative Law Center, Dallas, Texas. The Board believes that Mr.

recent industry developments.

company. Officers, directors and greater than ten percent stockholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they
file.

To our knowledge, based solely on a review of the copies of such reports furnished to us and written representations of our directors and officers that
no other reports were required, during the fiscal year ended December 31, 2018, all Section 16(a) filing requirements applicable to our officers, directors and
greater than ten percent beneficial owners were complied with.

ethics for our principal executive and financial officers are available on our corporate website at www.regenerx.com. If we make any substantive amendments

these codes to any executive officer or director, we will promptly disclose the nature of the amendment or waiver on our website.

Audit Committee and Audit Committee Financial Expert

Our board of directors periodically reviews the independence of our audit committee members and has determined that all current members of our
audit committee are independent under NYSE Amex listing standards. Although our common stock is no longer listed on the NYSE Amex exchange, we
have determined the independence of our audit committee members using the NYSE Amex definitions of independence.

Our board of directors has also determined that each of Mr. McNay and Mr. Elsey qualifies as an audit committee financial expert, as defined in

Described below are transactions and series of similar transactions that have occurred during fiscal 2018 to which we were a party or are a party in

which:

GtreeBNT

·
·

the amounts involved exceeded or will exceed $120,000; and
a  director,  executive  officer,  beneficial  owner  of  more  than  five  percent  of  any  class  of  our  voting  securities  or  any  member  of  their
immediate family had or will have a direct or indirect material interest.

In August 2017, the Company and GtreeBNT reached an agreement to expand the territorial definition of the RGN-137 License Agreement in Japan
in exchange for a series of payments, two of which were received in 2017 with the remaining two were received in 2018. Under the amendment the Territory
was expanded to include Europe, Canada, South Korea, Australia and Japan.

U.S. Joint Venture

On January 28, 2015, we announced that we had entered into a Joint Venture Agreement with GtreeBNT a shareholder of the Company. ReGenTree,
LLC was created under the Agreement and is jointly owned by us and GtreeBNT. ReGenTree intends to commercialize RGN-259 for treatment of dry eye and
neurotrophic  keratopathy,  an  orphan  indication  in  the  United  States.  GtreeBNT  will  be  responsible  for  funding  all  product  development  and
commercialization  efforts  and  holds  a  majority  interest  in  ReGenTree  that  varies  depending  on  development  milestones  achieved  and  eventual
commercialization  path,  if  successful.  In  conjunction  with  the  Joint  Venture  Agreement,  we  also  entered  into  a  royalty-bearing  license  with  ReGenTree
pursuant to which we granted to ReGenTree the right to develop and exclusively commercialize RGN-259 in the United States. We received a total of $1
million in two tranches under the terms of the License Agreement. The first tranche of $500,000 was received in March 2015 and a second in the amount of
$500,000, was received in September 2015. On April 6, 2016, we received $250,000 from ReGenTree and executed an amendment to the license agreement
on April 28, 2016. Under the amendment, the territorial rights were expanded to include Canada.

Our initial ownership interest in ReGenTree was 49% and has been reduced to 38.5% after filing of the final clinical study report with the FDA for
the Phase 3 trial for Dry Eye Syndrome completed in 2017. Based on when, and if, ReGenTree achieves certain additional development milestones in the U.S.
with  RGN-259,  our  equity  ownership  may  be  incrementally  reduced  to  between  38.5%  and  25%,  with  25%  being  the  final  equity  ownership  upon  FDA
approval of an NDA for Dry Eye Syndrome in the U.S. In addition to our equity ownership, RegeneRx retains a royalty on net sales that varies between single
and low double digits, depending on whether commercial sales are made by ReGenTree or a licensee. In the event ReGenTree is acquired, or a change of
control occurs following achievement of an NDA, RegeneRx shall be entitled to a minimum of 40% of all proceeds paid or payable and will forgo any future
royalties.

In September 2015, ReGenTree began a Phase 2/3 clinical trial in patients with dry eye syndrome (“DES”) and a Phase 3 clinical trial in patients
with neurotrophic keratopathy (“NK”), both in the U.S. In May 2016, we reported the results of the 317-patient Phase 2/3 trial (ARISE-1). The FDA approved
ReGenTree’s Phase 3 protocol for DES in late summer 2016 and we initiated a second Phase 3 trial (ARISE-2) that was completed in approximately 600
patients, the results of which have been reported elsewhere in this document.

The NK trial (SEER-1), a smaller study in an orphan population, has enrolled seventeen patients thus far, and has several additional patients being
screened,  with  a  goal  of  forty-six.  In  2018,  ReGenTree  disclosed  that  7  of  17  patients  enrolled  SEER-1  have  completely  healed.  While  these  preliminary
observations  are  encouraging,  it  should  be  noted  that  the  patients  and  treating  physicians  remain  masked  while  the  trial  is  on-going,  so  it  is  not  known
whether the healed patients are in the RGN-259 group, placebo group, or distributed among both. It is not known when this study will be completed.

Director Independence

Under  NYSE  Amex  listing  standards,  a  majority  of  the  members  of  a  listed  company’s  board  of  directors  must  qualify  as  “independent,”  as
affirmatively determined by the board. Although our common stock is no longer listed on the NYSE Amex exchange, we have determined the independence
of our directors using the NYSE Amex definitions of independence. Our board consults with counsel to ensure that its determinations are consistent with
relevant  securities  and  other  laws  and  regulations  regarding  the  definition  of  “independent,”  including  those  set  forth  in  pertinent  listing  standards  of  the
NYSE Amex, as in effect from time to time.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his family
members,  and  our  company,  our  senior  management  and  our  independent  auditors,  our  board  has  determined  that  the  following  three  directors  are
independent directors within the meaning of the applicable NYSE Amex listing standards: Mr. Elsey, Mr. Bove and Mr. McNay. In making this determination,
the board found that none of these directors had a material or other disqualifying relationship with us. Mr. Finkelstein, our President and Chief Executive
Officer, and Dr. Goldstein our Chief Scientific Officer, are not independent by virtue of their employment with us.

In determining the independence of Mr. Bove, the board of directors took into account the significant ownership of our common stock by Essetifin
S.p.A. and our License Agreement with Lee’s Pharmaceuticals. The board of directors does not believe that any of the transactions with Lee’s or Essetifin and
its affiliates described in this report has interfered or would reasonably be expected to interfere with Mr. Bove’s exercise of independent judgment in carrying
out his responsibilities as a director of our company.

Item 14. Principal Accounting Fees and Services.

The  following  table  represents  aggregate  fees  billed  to  us  for  the  fiscal  years  ended  December  31,  2018  and  2017  by  our  independent  registered

public accounting firm CohnReznick LLP. All such fees described below were approved by the audit committee.

Our audit committee has adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by our independent registered
public  accounting  firm.  The  policy  generally  pre-approves  specified  services  in  the  defined  categories  of  audit  services,  audit-related  services,  and  tax
services up to specified amounts. Pre-approval may also be given as part of the audit committee’s approval of the scope of the engagement of the independent
registered  public  accounting  firm  or  on  an  individual  explicit  case-by-case  basis  before  the  independent  registered  public  accounting  firm  is  engaged  to
provide each service. On a periodic basis, the independent registered public accounting firm reports to the audit committee on the status of actual costs for
approved services against the approved amounts.

The audit committee has determined that the rendering of the services other than audit services by CohnReznick LLP is compatible with maintaining

that firm’s independence.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
Regenerx Biopharmaceuticals, Inc.

Opinion on the Financial Statements

We  have  audited  the  accompanying  balance  sheets  of  RegeneRx  Biopharmaceuticals,  Inc.  (the  “Company”)  as  of  December  31,  2018  and  2017,  and  the
related statements of operations, changes in stockholders’ deficit and cash flows for the years then ended and the related notes (collectively referred to as the
“financial statements”). In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company
as  of  December  31,  2018  and  2017,  and  the  results  of  its  operations  and  its  cash  flows  for  the  years  then  ended  in  conformity  with  accounting  principles
generally accepted in the United States of America.

The Company's Ability to Continue as a Going Concern

The financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements,
the Company has incurred losses from operations since inception and will need additional capital to fund future operations. These conditions raise substantial
doubt about the Company's ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome
of this uncertainty.

Basis for Opinion

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

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

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

/s/ CohnReznick LLP

We have served as the Company’s auditor since 2012.

Notes to Financial Statements
December 31, 2018

1. ORGANIZATION AND BUSINESS

Organization and Nature of Operations.

RegeneRx Biopharmaceuticals, Inc. (“RegeneRx”, the “Company”, “We”, “Us”, “Our”), a Delaware corporation, was incorporated in 1982. We
are  focused  on  the  discovery  and  development  of  novel  molecules  to  accelerate  tissue  and  organ  repair.  Our  operations  are  confined  to  one  business
segment: the development and marketing of product candidates based on Thymosin Beta 4 (“Tß4”), an amino acid peptide.

Management Plans to Address Operating Conditions.

Our  strategy  is  aimed  at  being  capital  efficient  while  leveraging  our  portfolio  of  clinical  assets  by  seeking  strategic  relationships  with
organizations with clinical development capabilities including development capital. Currently, we have active partnerships in four major territories: North
America, Europe, China and Pan Asia. In each case, the cost of development is being borne by our partners with no financial obligation for RegeneRx.
We still have significant clinical assets to develop, primarily RGN-352 (injectable formulation of Tß4 for cardiac and CNS disorders) in the U.S., Pan
Asia, and Europe, and RGN-259 in the EU. Our goal is to wait until satisfactory results are obtained from the current ophthalmic clinical program in the
U.S. before moving into the EU. However, we intend to continue to develop RGN-352, our injectable systemic product candidate for cardiac and central
nervous system indications, either by obtaining grants to fund a Phase 2a clinical trial in the cardiovascular or central nervous system fields or finding a
suitable partner with the resources and capabilities to develop it as we have with RGN-259.

Since  inception,  and  through  December  31,  2018,  we  have  an  accumulated  deficit  of  $106  million  and  we  had  cash  and  cash  equivalents  of
$237,261  as  of  December  31,  2018.  We  anticipate  incurring  additional  operating  losses  in  the  future  as  we  continue  to  explore  the  potential  clinical
benefits  of  Tß4-based  product  candidates  over  multiple  indications.  We  have  entered  into  a  series  of  strategic  partnerships  under  licensing  and  joint
venture agreements where our partners are responsible for advancing development of our product candidates by sponsoring multiple clinical trials. On
February  27,  2019,  we  sold  a  series  of  convertible  promissory  notes  to  management,  the  Company’s  Board  of  Directors  and  accredited  investors
including Essetifin S.p.A., our largest shareholder. The sale of the notes will result in gross proceeds to the Company of $1,300,000 over two closings.
The first closing in the amount of $650,000 occurred on February 27th and the second closing, also in the amount of $650,000 will occur within three
days of the Company providing notice of the enrollment of the first patent in the ARISE-3 clinical trial in DES sponsored by ReGenTree. ReGenTree has
informed us that they now expect the ARISE-3 clinical trial to occur in the second quarter of 2019. Because the Company does not control the timing of
the ARISE-3 clinical trial, we cannot be certain that this timing is correct or that it may not change. The notes contain a $0.12 conversion price and the
purchasers also received a warrant exercisable at $0.18 to purchase additional shares of common stock equal to 75% of the number of shares into which
each note is initially convertible. At present, with the receipt of the sale proceeds from the first closing coupled with the anticipated proceeds from the
second closing, we will have sufficient cash to fund planned operations through the first quarter of 2020.

While  we  successfully  secured  additional  operating  capital  to  continue  operations  through  the  first  quarter  of  2020  we  will  need  substantial
additional funds in order to significantly advance development of our unlicensed programs. Accordingly, we will continue to evaluate opportunities to
raise  additional  capital  and  are  in  the  process  of  exploring  various  alternatives,  including,  without  limitation,  a  public  or  private  placement  of  our
securities, debt financing, corporate collaboration and licensing arrangements, or the sale of our Company or certain of our intellectual property rights.

These  factors  raise  substantial  doubt  about  our  ability  to  continue  as  a  going  concern.  The  accompanying  financial  statements  have  been
prepared assuming that we will continue as a going concern. This basis of accounting contemplates the recovery of our assets and the satisfaction of our
liabilities in the normal course of business.

Although  we  intend  to  continue  to  seek  additional  financing  or  additional  strategic  partners,  we  may  not  be  able  to  complete  a  financing  or
corporate transaction, either on favorable terms or at all. If we are unable to complete a financing or strategic transaction, we may not be able to continue
as  a  going  concern  after  our  funds  have  been  exhausted,  and  we  could  be  required  to  significantly  curtail  or  cease  operations,  file  for  bankruptcy  or
liquidate  and  dissolve.  There  can  be  no  assurance  that  we  will  be  able  to  obtain  any  sources  of  funding.  The  financial  statements  do  not  include  any
adjustments relating to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should we
be forced to take any such actions.

F-7

 
 
 
 
 
 
 
 
 
 
 
 
In addition to our current operational requirements, we continually refine our operating strategy and evaluate alternative clinical uses of Tß4.
However, substantial additional resources will be needed before we will be able to achieve sustained profitability. Consequently, we continually evaluate
alternative sources of financing such as the sharing of development costs through strategic collaboration agreements. There can be no assurance that our
financing  efforts  will  be  successful  and,  if  we  are  not  able  to  obtain  sufficient  levels  of  financing,  we  would  delay  certain  clinical  and/or  research
activities and our financial condition would be materially and adversely affected. Even if we are able to obtain sufficient funding, other factors including
competition,  dependence  on  third  parties,  uncertainty  regarding  patents,  protection  of  proprietary  rights,  manufacturing  of  peptides,  and  technology
obsolescence could have a significant impact on us and our operations.

To  achieve  profitability,  we,  and/or  a  partner,  must  successfully  conduct  pre-clinical  studies  and  clinical  trials,  obtain  required  regulatory
approvals and successfully manufacture and market those pharmaceuticals we wish to commercialize. The time required to reach profitability is highly
uncertain, and there can be no assurance that we will be able to achieve sustained profitability, if at all.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of
America (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported earnings, financial position and various
disclosures.  Critical  accounting  policies  involved  in  applying  our  accounting  policies  are  those  that  require  management  to  make  assumptions  about
matters that are highly uncertain at the time the accounting estimate was made and those for which different estimates reasonably could have been used
for the current period. Critical accounting estimates are also those which are reasonably likely to change from period to period and would have a material
impact on the presentation of our financial condition, changes in financial condition or results of operations. Our most critical accounting estimates relate
to  accounting  policies  for  revenue  recognition,  valuation  of  derivatives  and  share-based  arrangements.  Management  bases  its  estimates  on  historical
experience and on various other assumptions that it believes are reasonable under the circumstances. Actual results could differ from these estimates.

Cash and Cash Equivalents. Cash and cash equivalents consist of cash and highly-liquid investments with original maturities of three months or

less when acquired and are stated at cost that approximates their fair market value.

Concentration of Credit Risk. Financial instruments, which potentially subject the Company to concentrations of credit risk, consist primarily of
cash and cash equivalents. We limit our exposure to credit loss by placing our cash and cash equivalents with high quality financial institutions and, in
accordance with our investment policy, in securities that are rated investment grade.

Property  and  Equipment.  Property  and  equipment  consist  of  office  furniture  and  equipment  and  is  stated  at  cost  and  depreciated  over  the
estimated useful lives of the assets (generally two to five years) using the straight-line method. Expenditures for maintenance and repairs which do not
significantly prolong the useful lives of the assets are charged to expense as incurred. Depreciation expense was $2,753 and $3,048 for the years ended
December 31, 2018 and 2017, respectively.

Impairment of Long-lived Assets. When we record long-lived assets, our policy is to regularly perform reviews to determine if and when the

carrying value of our long-lived assets becomes impaired. During the years ended December 31, 2018 and 2017, no impairment losses were recorded.

Convertible Notes with Detachable Warrants. In accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards
Codification (“ASC”) 470-20, Debt with Conversion and Other Options, the proceeds received from convertible notes are allocated to the instruments
based on the relative fair values of the convertible notes without the warrants and of the warrants themselves at the time of issuance. The portion of the
proceeds allocated to the warrants is recognized as additional paid-in capital and a debt discount. The debt discount related to warrants is accreted into
interest expense through maturity of the notes.

Derivative  Financial  Instruments.  Derivative  financial  instruments  consist  of  financial  instruments  or  other  contracts  that  contain  a  notional
amount and one or more underlying variables (e.g. interest rate, security price or other variable), which require no initial net investment and permit net
settlement. Derivative financial instruments may be free-standing or embedded in other financial instruments. Further, derivative financial instruments
are initially, and subsequently, measured at fair value and recorded as liabilities or, in rare instances, assets.

F-8

 
 
 
 
 
 
 
 
 
 
 
 
The Company does not use derivative financial instruments to hedge exposures to cash-flow, market or foreign-currency risks. However, the
Company has issued financial instruments including warrants that are either (i) not afforded equity classification, (ii) embody risks not clearly and closely
related to host contracts, or (iii) may be net-cash settled by the counterparty. In certain instances, these instruments are required to be carried as derivative
liabilities, at fair value, in the Company’s financial statements.

The Company estimates the fair values of its derivative financials instrument using the Black-Scholes option pricing model because it embodies
all of the requisite assumptions (including trading volatility, estimated terms and risk-free rates) necessary to fair value these instruments. Estimating fair
values of derivative financial instruments requires the development of significant and subjective estimates that may, and are likely to, change over the
duration  of  the  instrument  with  related  changes  in  internal  and  external  market  factors.  In  addition,  option-based  techniques  are  highly  volatile  and
sensitive  to  changes  in  the  trading  market  price  of  the  Company’s  common  stock,  which  has  a  high-historical  volatility.  Since  derivative  financial
instruments are initially and subsequently carried at fair values, the Company’s operating results reflect the volatility in these estimate and assumption
changes in each reporting period.

Upon the adoption of new accounting guidance on January 1, 2018, the embedded conversion features in the Company’s convertible notes are

no longer accounted for as derivative liabilities.

Revenue Recognition. Subsequent to the adoption of Accounting Standards Codification Revenue from Contracts with Customers (“ASC 606”)

on January 1, 2018

The Company analyzes contracts to determine the appropriate revenue recognition using the following steps: (i) identification of contracts with
customers, (ii) identification of distinct performance obligations in the contract, (iii) determination of contract transaction price, (iv) allocation of contract
transaction  price  to  the  performance  obligations  and  (v)  determination  of  revenue  recognition  based  on  timing  of  satisfaction  of  the  performance
obligation. The Company recognizes revenues upon the satisfaction of its performance obligation (upon transfer of control of promised goods or services
to our customers) in an amount that reflects the consideration to which it expects to be entitled to in exchange for those goods or services. Whenever we
determine  that  an  arrangement  should  be  accounted  for  as  a  single  unit  of  accounting,  we  must  determine  the  period  over  which  the  performance
obligations will be performed, and revenue will be recognized. Revenue will be recognized using either a relative performance or straight-line method.
We  recognize  revenue  using  the  relative  performance  method  provided  that  we  can  reasonably  estimate  the  level  of  effort  required  to  complete  our
performance obligations under an arrangement and such performance obligations are provided on a best-efforts basis. Revenue recognized is limited to
the lesser of the cumulative amount of payments received or the cumulative amount of revenue earned, as determined using the relative performance
method, as of each reporting period.

The  Company’s  contracts  with  customers  may  at  times  include  multiple  promises  to  transfer  products  and  services.  Contracts  with  multiple
promises are analyzed to determine whether the promises, which may include a license together with performance obligations such as providing a clinical
supply of product and steering committee services, are distinct and should be accounted for as separate performance obligations or whether they must be
accounted  for  as  a  single  performance  obligation.  The  Company  accounts  for  individual  performance  obligations  separately  if  they  are  distinct.
Determining whether products and services are considered distinct performance obligations may require significant judgment. If we cannot reasonably
estimate when our performance obligation either ceases or becomes inconsequential and perfunctory, then revenue is deferred until we can reasonably
estimate  when  the  performance  obligation  ceases  or  becomes  inconsequential.  Revenue  is  then  recognized  over  the  remaining  estimated  period  of
performance.

Whenever the Company determines that an arrangement should be accounted for as a combined performance obligation, we must determine the
period  over  which  the  performance  obligation  will  be  performed  and  when  revenue  will  be  recognized.  Revenue  is  recognized  using  either  a  relative
performance or straight-line method. We recognize revenue using the relative performance method provided that the we can reasonably estimate the level
of  effort  required  to  complete  our  performance  obligation  under  an  arrangement  and  such  performance  obligation  is  provided  on  a  best-efforts  basis.
Revenue recognized is limited to the lesser of the cumulative amount of payments received or the cumulative amount of revenue earned, as determined
using the relative performance method, as of each reporting period.

If  the  Company  cannot  reasonably  estimate  the  level  of  effort  required  to  complete  our  performance  obligation  under  an  arrangement,  the
performance  obligation  is  provided  on  a  best-efforts  basis  and  we  can  reasonably  estimate  when  the  performance  obligation  ceases  or  the  remaining
obligations become inconsequential and perfunctory, then the total payments under the arrangement, excluding royalties and payments contingent upon
achievement of substantive milestones, would be recognized as revenue on a straight-line basis over the period we expect to complete our performance
obligations. Revenue is limited to the lesser of the cumulative amount of payments received or the cumulative amount of revenue earned, as determined
using the straight-line basis, as of the period ending date.

If the Company cannot reasonably estimate when our performance obligation either ceases or becomes inconsequential and perfunctory, revenue
is deferred until we can reasonably estimate when the performance obligation ceases or becomes inconsequential. Revenue is then recognized over the
remaining estimated period of performance.

F-9

 
 
 
 
 
 
 
 
 
 
 
At  the  inception  of  each  arrangement  that  includes  development  milestone  payments,  the  Company  evaluates  the  probability  of  reaching  the
milestones  and  estimates  the  amount  to  be  included  in  the  transaction  price  using  the  most  likely  amount  method.  If  it  is  probable  that  a  significant
revenue reversal would not occur in the future, the associated milestone value is included in the transaction price. Milestone payments that are not within
the control of the Company or the licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received
and therefore revenue recognized is constrained as management is unable to assert that a reversal of revenue would not be possible. The transaction price
is then allocated to each performance obligation on a relative standalone selling price basis, for which the Company recognizes revenue as or when the
performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Company re-evaluates the probability of
achievement of such development milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such
adjustments are recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of adjustment.

Amounts  received  prior  to  satisfying  the  above  revenue  recognition  criteria  are  recorded  as  unearned  revenue  in  our  accompanying  balance

sheets.

Contract assets are generated when contractual billing schedules differ from revenue recognition timing. Contract assets represent a conditional
right to consideration for satisfied performance obligations that becomes a billed receivable when the conditions are satisfied. There were no contract
assets as of December 31, 2018.

Contract  liabilities  result  from  arrangements  where  we  have  received  payment  in  advance  of  performance  under  the  contract.  Changes  in

contract liabilities are generally due to either receipt of additional advance payments or our performance under the contract.

We have the following amounts recorded for contract liabilities:

Unearned revenue

  $

2,254,848    $

2,124,515 

  December 31, 2018    December 31, 2017 

The  contract  liabilities  amount  disclosed  above  as  of  December  31,  2018,  is  primarily  related  to  revenue  being  recognized  on  a  straight-line
basis over periods ranging from 23 to 30 years, which, in management’s judgment, is the best measure of progress towards satisfying the performance
obligations and represents the Company’s best estimate of the period of the obligation.

Revenue recognized from contract liabilities during the year ended December 31, 2018, totaled $58,073. Revenue is expected to be recognized

in the future from contract liabilities as the related performance obligations are satisfied.

For details about the Company’s revenue recognition policy prior to the adoption of ASC 606, refer to the Company’s annual report on form 10-

K for the year ended December 31, 2017.

Variable  Interest  Entities  On  January  28,  2015,  the  Company  entered  into  a  Joint  Venture  Agreement  with  GtreeBNT,  a  shareholder  in  the
Company.  The  Joint  Venture  Agreement  provides  for  the  operation  of  the  joint  venture,  jointly  owned  by  the  Company  and  GtreeBNT,  which  is
commercializing RGN-259 for the treatment of dry eye and neurotrophic keratopathy in the U.S. and Canada. The Company has determined that the Joint
Venture is a “variable interest entity”, since the total equity investment at risk is not sufficient to permit the Joint Venture to finance its activities without
additional subordinated financial support. Further, because of GtreeBNT’s majority equity stake in the Joint Venture, voting control, control of the board
of directors, and substantive management rights, and given that the Company does not have the power to direct the Joint Venture’s activities that most
significantly impact its economic performance, the Company determined that it is not the primary beneficiary of the Joint Venture and therefore is not
required to consolidate the Joint Venture. The Company reports its equity stake in the Joint Venture using the equity method of accounting because, while
it does not control the Joint Venture, the Company can exert significant influence over the Joint Ventures activities by virtue of its board representation.

Because the Company is not obligated to fund the Joint Venture and has not provided any financial support and has no commitment to provide
financial support in the future to the Joint Venture, the carrying value of its investment in the Joint Venture is zero at both December 31, 2018 and 2017.
As a result, the Company is not recognizing its share (38.5%) of the Joint Venture’s operating losses and will not recognize any such losses until the Joint
Venture produces net income (as opposed to net losses) and at that point the Company will reduce its share of the Joint Venture’s net income by its share
of previously suspended net losses. As of December 31, 2018, because it has not provided any financial support, the Company has no financial exposure
as a result of its variable interest in the Joint Venture.

Research and Development. Research and development (“R&D”) costs are expensed as incurred and include all of the wholly-allocable costs
associated with our various clinical programs passed through to us by our outsourced vendors. Those costs include: manufacturing Tb4; formulation of
Tb4 into the various product candidates; stability for both Tb4 and the various formulations; pre-clinical toxicology; safety and pharmacokinetic studies;
clinical trial management; medical oversight; laboratory evaluations; statistical data analysis; regulatory compliance; quality assurance; and other related
activities. R&D includes cash and non-cash compensation, employee benefits, travel and other miscellaneous costs of our internal R&D personnel, who
are wholly dedicated to R&D efforts. R&D also includes a pro-ration of our common infrastructure costs for office space and communications.

Patent Costs. Costs related to filing and pursuing patent applications are recognized as general and administrative expenses as incurred since

recoverability of such expenditures is uncertain.

Income Taxes. Income  taxes  are  accounted  for  under  the  asset  and  liability  method.  Deferred  tax  assets  and  liabilities  are  recognized  for  the
estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their
respective tax basis and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to
apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and
liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Tax Cuts and Jobs Act, which was enacted
on December 22, 2017, included a number of changes to existing U.S. tax laws, most notably the reduction of the U.S. corporate income tax rate from
35% to 21%, beginning in 2018. We remeasured our deferred tax assets and deferred tax liabilities as of December 31, 2017 to reflect the reduction in the
enacted U.S. corporate income tax rate.

The  ultimate  realization  of  deferred  tax  assets  is  dependent  upon  the  generation  of  future  taxable  income  during  the  periods  in  which  those
temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and
tax planning strategies in making that assessment. We recorded a full valuation allowance against all estimated net deferred tax assets at December 31,
2018 and 2017.

We  recognize  the  effect  of  income  tax  positions  only  if  those  positions  are  more  likely  than  not  of  being  sustained.  Recognized  income  tax
positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the
period in which the change in judgment occurs. Our policy for recording interest and penalties associated with audits is that penalties and interest expense
are recorded in “Income taxes” in our statements of operations.

We  have  significant  net  operating  loss  carryforwards  to  potentially  reduce  future  federal  and  state  taxable  income,  and  research  and
experimentation tax credit carryforwards available to potentially offset future federal and state income taxes. Use of our net operating loss and research
and experimentation credit carryforwards may be limited due to changes in our ownership as defined within Section 382 of the Internal Revenue Code.

Net (Loss) Income Per Common Share. Basic net (loss) income per common share for 2018 and 2017 is based on the weighted-average number
of shares of common stock outstanding during the years. Diluted loss per share is based on the weighted-average number of shares of common stock
outstanding during each year in which a loss is incurred potentially dilutive shares are excluded because the effect is antidilutive. In years where there is
net income, diluted income per share is based on the weighted-average number of shares of common stock outstanding plus dilutive securities with a
purchase  or  conversion  price  below  the  per  share  price  of  our  common  stock  on  the  last  day  of  the  year.  The  potentially  dilutive  securities  include
14,182,086  shares  and  25,146,533  shares  in  2018  and  2017,  respectively,  reserved  for  the  conversion  of  convertible  debt  or  exercise  of  outstanding
options and warrants. For the year ended December 31, 2017, 13,485,897 dilutive securities related to convertible debt and options, were included in the
diluted income per share calculation.

Share-Based Compensation.  We  measure  share-based  compensation  expense  based  on  the  grant  date  fair  value  of  the  awards  which  is  then
recognized over the period which service is required to be provided. We estimate the grant date fair value using the Black-Scholes option-pricing model
(“Black-Scholes”).  We  recognized  $276,129  and  $271,377  in  share-based  compensation  expense  for  the  years  ended  December  31,  2018  and  2017,
respectively.

Fair  Value  of  Financial  Instruments.  The  carrying  amounts  of  our  financial  instruments,  as  reflected  in  the  accompanying  balance  sheets,
approximate fair value. Financial instruments consist of cash and cash equivalents, accounts payable, and convertible debt and accrued interest. Because
the convertible debt with an interest rate of 5% is with related parties, it was not practicable to estimate the effect of subjective risk factors, which might
influence the value of the debt. The most significant of these risk factors include the lack of collateralization.

Recently Adopted Accounting Pronouncements.

In  May  2014,  the  FASB  issued  Accounting  Standards  Update  (“ASU”)  2014-09,  Revenue  from  Contracts  with  Customers,  which  provides
guidance for revenue recognition for contracts, superseding the previous revenue recognition requirements, along with most existing industry-specific
guidance. The guidance requires an entity to review contracts in five steps: 1) identify the contract, 2) identify performance obligations, 3) determine the
transaction price, 4) allocate the transaction price, and 5) recognize revenue. In March 2016, the FASB issued an accounting standard update to clarify the
implementation  guidance  on  principal  versus  agent  considerations.  In  April  2016,  the  FASB  issued  an  accounting  standard  update  to  clarify  the
identification of performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. In May 2016,
the FASB issued an accounting standard update to clarify guidance in certain areas and add some practical expedients to the guidance. The amendments
in these 2016 updates do not change the core principle of the previously issued guidance in May 2014. Effective January 1, 2018, the Company adopted
ASU 2014-09 (Topic 606) using the modified retrospective method through a cumulative adjustment to equity, which resulted in an immaterial difference
and no adjustment to our opening balance of accumulated deficit as of January 1, 2018.

In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives
and  Hedging  (Topic  815):  (Part  I)  Accounting  for  Certain  Financial  Instruments  with  Down  Round  Features,  (Part  II)  Replacement  of  the  Indefinite
Deferral  for  Mandatorily  Redeemable  Financial  Instruments  of  Certain  Nonpublic  Entities  and  Certain  Mandatorily  Redeemable  Noncontrolling
Interests with a Scope Exception. Part I of this Update addresses the complexity of accounting for certain financial instruments with down round features.
Down round features are features of certain equity-linked instruments (or embedded features) that result in the strike price being reduced on the basis of
the pricing of future equity offerings. When determining whether certain financial instruments should be classified as liabilities or equity instruments, a
down round feature no longer precludes equity classification when assessing whether the instrument is indexed to an entity’s own stock. Part II of this
Update addresses the difficulty of navigating Topic 480, Distinguishing Liabilities from Equity, because of the existence of extensive pending content in
the FASB ASC. For public business entities, the amendments in Part I of this Update are effective for years beginning after December 15, 2018. Effective
January  1,  2018,  the  Company  adopted  ASU  2017-11.  As  a  result,  the  December  31,  2017  qualifying  liabilities  of  approximately  $1.3  million  were
reclassified  as  equity  as  of  January  1,  2018.  Accordingly,  no  previously  issued  financial  statements  were  adjusted  as  this  guidance  was  applied
prospectively.

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718) Scope of Modification Accounting. ASU 2017-09
provides clarification on when modification accounting should be used for changes to the terms or conditions of a share-based payment award. This ASU
does not change the accounting for modifications but clarifies that modification accounting guidance should only be applied if there is a change to the
value, vesting conditions, or award classification and would not be required if the changes are considered non-substantive. The Company adopted ASU
2017-09 in the first quarter of 2018 and the adoption of this ASU did not have a material effect on the financial statements.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASC 842”), which amends the existing accounting standards for leases.
The new standard requires lessees to record a right-of-use (“ROU”) asset and a corresponding lease liability on the balance sheet (with the exception of
short-term leases), whereas under current accounting standards, the Company’s lease portfolio consists of an operating lease and is not recognized on its
balance  sheets.  The  new  standard  also  requires  expanded  disclosures  regarding  leasing  arrangements.  The  new  standard  is  effective  for  the  Company
beginning  January  1,  2019.  In  July  2018,  the  FASB  issued  ASU  2018-11,  Leases  (Topic  842):  Targeted  Improvements,  which  provides  an  alternative
modified transition method. Under this method, the cumulative-effect adjustment to the opening balance of retained earnings is recognized on the date of
adoption with prior periods not restated.

The new standard provides a number of optional practical expedients in transition. The Company expects to elect: (1) the ‘package of practical
expedients’, which permits it not to reassess under the new standard its prior conclusions about lease identification, lease classification, and initial direct
costs; (2) the use-of-hindsight; and (3) the practical expedient pertaining to land easements. In addition, the new standard provides practical expedients
for an entity’s ongoing accounting that the Company anticipates making, such as the (1) the election for certain classes of underlying asset to not separate
non-lease components from lease components and (2) the election for short-term lease recognition exemption for all leases that qualify.

The  Company  will  adopt  ASC  842  as  of  January  1,  2019,  using  the  alternative  modified  transition  method.  The  Company  has  substantially
completed its evaluation of the impact on the Company’s lease portfolio. The Company believes the largest impact will be on the balance sheet for the
accounting of its facilities-related lease, which is its only operating lease entered as a lessee. This lease will be recognized under the new standard as an
ROU asset and operating lease liability. The Company will also be required to provide expanded disclosures for its leasing arrangement. As of December
31, 2018, the Company had approximately $77,000 of undiscounted future minimum operating lease commitments that are not recognized on its balance
sheet as determined under the current standard.

While  substantially  complete,  the  Company  is  still  in  the  process  of  finalizing  its  evaluation  of  the  effect  of  ASC  842  on  the  Company’s
financial statements and disclosures. The Company will finalize its accounting assessment and quantitative impact of the adoption during the first quarter
of fiscal year 2019. As the Company completes its evaluation of this new standard, new information may arise that could change the Company’s current
understanding of the impact to leases. Additionally, the Company will continue to monitor industry activities and any additional guidance provided by
regulators, standards setters, or the accounting profession, and adjust the Company’s assessment and implementation plans accordingly.

In June 2018, the FASB issued ASU 2018-07: Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based
Payment Accounting. This ASU expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from non-
employees, and as a result, the accounting for share-based payments to non-employees will be substantially aligned. ASU 2018-07 is effective for fiscal
years  beginning  after  December  15,  2018,  including  interim  periods  within  that  fiscal  year,  early  adoption  is  permitted  but  no  earlier  than  an  entity’s
adoption  date  of  Topic  606.  The  Company  does  not  expect  this  new  guidance  will  have  a  material  impact  on  its  financial  statements  and  related
disclosures.

The Company has evaluated all other issued and unadopted ASUs and believes the adoption of these standards will not have a material impact

on its results of operations, financial position or cash flows.

3. FAIR VALUE MEASUREMENTS

The authoritative guidance for fair value measurements defines fair value as the exchange price that would be received for an asset or paid to
transfer  a  liability  (an  exit  price)  in  the  principal  or  the  most  advantageous  market  for  the  asset  or  liability  in  an  orderly  transaction  between  market
participants on the measurement date. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii)
able  to  transact,  and  (iv)  willing  to  transact.  The  guidance  describes  a  fair  value  hierarchy  based  on  the  levels  of  inputs,  of  which  the  first  two  are
considered observable and the last unobservable, that may be used to measure fair value which are the following:

•

•

•

Level 1 — Quoted prices in active markets for identical assets and liabilities.

Level 2 — Observable inputs other than quoted prices in active markets for identical assets and liabilities.

Level 3 — Unobservable inputs.

As of December 31, 2018 and 2017, our only qualifying assets that required measurement under the foregoing fair value hierarchy were funds
held in our Company bank accounts included in Cash and Cash Equivalents valued at $237,261 and $181,708, respectively, using Level 1 inputs. Our
December 31, 2017 balance sheet reflects qualifying liabilities resulting from the price protection provision in the convertible promissory notes issued in
March, July and September of 2013 and January 2014 (see Note 7). Previously we evaluated the derivative liability embedded in the series of convertible
notes using the Black-Scholes model to determine if an adjustment to the carrying value of the liability was required each reporting period. Given the
conditions  surrounding  the  trading  of  the  Company’s  equity  securities,  the  Company  had  valued  its  derivative  instruments  related  to  embedded
conversion features from the issuance of convertible debentures in accordance with the Level 3 guidelines. Our December 31, 2018 balance sheet no
longer  reflects  these  liabilities  pursuant  to  the  adoption  ASU  2017-11.  As  a  result,  the  December  31,  2017  qualifying  liabilities  were  reclassified  as
equity.

For  the  year  ended  December  31,  2018,  the  following  table  reconciles  the  beginning  and  ending  balances  for  financial  instruments  that  are

recognized at fair value in these financial statements.

4. LICENSES, INTELLECTUAL PROPERTY, AND RELATED PARTY TRANSACTIONS

We have an exclusive, worldwide licensing agreement with the National Institutes of Health (“NIH”) for all claims to Tb4 within their broadly-
defined patent application. In exchange for this exclusive worldwide license, we must make certain royalty and milestone payments to the NIH. In 2013,
we  amended  certain  provisions  of  the  exclusive  license;  we  were  permitted  to  credit  amounts  paid  to  prosecute  or  maintain  the  licensed  patent  rights
during 2013 calendar year against the 2013 minimum annual royalty of $25,000. Beginning in 2014 the minimum annual royalty is $2,000. No assurance
can be given as to whether or when a patent will be issued, or as to any claims that may be included or excluded within the patent. We have also filed
numerous additional patent applications covering various compositions, uses, formulations and other components of Tb4, as well as to novel peptides
resulting from our research efforts. Some of these patents have been issued, while many patent applications are still pending.

We have also entered into an agreement with a university under the terms of which we have received an exclusive license to technology and
intellectual  property.    The  agreement,  which  is  generally  cancelable  by  us,  provided  for  the  payment  of  a  license  issue  fee  and/or  minimum  annual
payments.  The initial license fee of $25,000 was paid in 2010 and no minimum fees were due for the year ended December 31, 2011. Beginning in 2012,
minimum  annual  maintenance  fees  are  $5,000  annually  which  was  paid  in  2012  but  has  not  been  paid  since.  In  addition,  the  agreements  provide  for
payments upon the achievement of certain milestones in product development.  The agreement also requires us to fund certain costs associated with the
filing and prosecution of patent applications. In February 2013, this agreement was amended to include additional technology and intellectual property.
The expanded license does not require payment of an initial license fee or additional annual maintenance fees but will be subject to payments upon the
achievement of certain milestones for a product developed under the amended license of the additional technology and intellectual property.

All license fees are included in Research and Development in the accompanying statements of operations.

In 2012, we entered into a License Agreement (the “Agreement”) with Lee’s Pharmaceutical (HK) Limited (“Lee’s”), headquartered in Hong
Kong, for the license of Thymosin Beta 4 in any pharmaceutical form, including our RGN-259, RGN-352 and RGN-137 product candidates, in China,
Hong Kong, Macau and Taiwan. Under the License Agreement, we are eligible to receive milestone payments and royalties, ranging from low double
digit to high single digit percentages of any commercial sales of the licensed products. Lee’s will pay for all developmental costs associated with each
product  candidate.  We  will  provide  Tß4  to  Lee’s  at  no  charge  for  a  Phase  2  ophthalmic  clinical  trial  and  will  provide  Tß4  to  Lee’s  for  all  other
developmental  and  clinical  work  at  a  price  equal  to  our  cost.  We  will  also  have  the  right  to  exclusively  license  any  improvements  made  by  Lee’s  to
RegeneRx’s  products  outside  of  the  licensed  territory.  Lee’s  paid  us  $200,000  upon  signing  of  a  term  sheet  in  March  2012,  and  Lee’s  paid  us  an
additional $200,000 upon signing of the definitive license agreement. The Company is accounting for the License Agreement as a revenue arrangement.
Since  participation  in  the  joint  development  committee  is  required  it  was  deemed  to  be  a  material  promise.  Management  has  concluded  that  the
participation in the joint development committee is not distinct from other promised goods and services. The Company assessed the License Agreement
in accordance with ASC 606. The Company evaluated the promised goods and services under the License Agreement and determined that there was one
combined performance obligation representing a series of distinct goods and services including the license to research, develop and commercialize Tß4 in
any  pharmaceutical  form  and  participation  in  the  joint  development  committee.  To-date,  management  has  not  been  able  to  reasonably  measure  the
outcome of the performance obligation, but still expects to recover the costs incurred in satisfying the performance obligation. Accordingly, the Company
has deferred all revenue until such time that it can reasonably measure the outcome of the performance obligation or until the performance obligation
becomes  onerous.  As  of  December  31,  2018  and  2017,  we  have  unearned  revenue  totaling  $400,000  pursuant  to  this  Agreement.  Revenue  will  be
recognized  for  future  royalty  payments  as  they  are  earned.  In  February  2019,  the  License  Agreement  was  amended  and  assigned  by  Lee’s  to  their
affiliate, Zhaoke Ophthalmology Pharmaceutical Limited. There are no economic changes to the License Agreement.

On March 7, 2014, we entered into license agreements with GtreeBNT Co., Ltd. The two Licensing Agreements are for the license of territorial

rights to two of our Thymosin Beta 4-based products candidates, RGN-259 and RGN-137.

Under  the  License  Agreement  for  RGN-259,  our  preservative-free  eye  drop  product  candidate,  GtreeBNT  will  have  the  right  to  develop  and
commercialize  RGN-259  in  Asia  (excluding  China,  Hong  Kong,  Taiwan,  and  Macau).  The  rights  will  be  exclusive  in  Korea,  Japan,  Australia,  New
Zealand,  Brunei,  Cambodia,  East  Timor,  Indonesia,  Laos,  Malaysia,  Mongolia,  Myanmar  (Burma),  Philippines,  Singapore,  Thailand,  Vietnam,  and
Kazakhstan,  and  semi-exclusive  in  India,  Pakistan,  Bangladesh,  Bhutan,  Maldives,  Nepal,  Sri  Lanka,  Kyrgyzstan,  Tajikistan,  Turkmenistan  and
Uzbekistan, collectively, the Territory (the “259 Territory”). Under the 259 License Agreement we are eligible to receive aggregate potential milestone
payments of up to $3.5 million. In addition, we are eligible to receive royalties of a low double digit percentage of any commercial sales of the licensed
product sold by GtreeBNT in the 259 Territory.

Under the License Agreement for RGN-137, our topical dermal gel product candidate, GtreeBNT will have the exclusive right to develop and
commercialize RGN-137 in the U.S. (the “137 Territory”). Under the 137 License Agreement we are eligible to receive aggregate potential milestone
payments  of  up  to  $3.5  million.  In  addition,  we  are  eligible  to  receive  royalties  of  a  low  double-digit  percentage  of  any  commercial  sales  of  the
Company’s  licensed  product  sold  by  GtreeBNT  in  the  137  Territory.  In  August  2017,  we  amended  the  License  Agreement  for  RGN-137  held  by
GtreeBNT.  Under  the  amendment,  the  137  Territory  was  expanded  to  include  Europe,  Canada,  South  Korea,  Australia  and  Japan.  Under  the  License
Agreement, the Company received a series of non-refundable payments and is entitled to receive royalties on the future sales of products. The Company
is accounting for the license agreement as a revenue arrangement. Since participation in the joint development committee is required it was deemed to be
a material promise. Management has concluded that the participation in the joint development committee is not distinct from other promised goods and
services. The Company assessed the license agreement in accordance with ASC 606. The Company evaluated the promised goods and services under the
license agreement and determined that there was one combined performance obligation representing a series of distinct goods and services including the
license  to  research,  develop  and  commercialize  RGN-137  and  participation  in  the  joint  development  committee.  Revenue  is  being  recognized  on  a
straight-line  basis  over  a  period  of  23  years,  which,  in  management’s  judgment,  is  the  best  measure  of  progress  towards  satisfying  the  performance
obligation and represents the Company’s best estimate of the period of the obligation. As of December 31, 2018 and 2017, we have unearned revenue
totaling $753,623 and $575,971, respectively, pursuant to this agreement. Revenue will be recognized for future royalty payments as they are earned.

Each License Agreement contains diligence provisions that require the initiation of certain clinical trials within certain time periods that, if not
met, would result in the loss of rights or exclusivity in certain countries. GtreeBNT will pay for all developmental costs associated with each product
candidate. We have the right to exclusively license any improvements made by GtreeBNT to our products outside of the licensed territory on a royalty
free  basis.  The  two  firms  have  created  a  joint  development  committee  and  continue  to  discuss  the  development  of  the  licensed  products  and  share
information relating thereto. Both companies will also share all non-clinical and clinical data and other information related to development of the licensed
product candidates.

On January 28, 2015, the Company entered into the Joint Venture Agreement with GtreeBNT, a shareholder in the Company. The Joint Venture
Agreement  provides  for  the  creation  of  the  Joint  Venture,  jointly  owned  by  the  Company  and  GtreeBNT,  which  is  commercializing  RGN-259  for
treatment of dry eye and neurotrophic keratopathy in the U.S. and Canada.

GtreeBNT is solely responsible for funding all the product development and commercialization efforts of the Joint Venture. GtreeBNT made an
initial contribution of $3 million in cash and received an initial equity stake of 51%. RegeneRx’s ownership interest in ReGenTree was reduced to 38.5%
when the Clinical Study Report was filed for the Phase 2/3 dry eye clinical trial. Based on when, and if, certain additional development milestones are
achieved in the U.S. with RGN-259, our equity ownership may be incrementally reduced to between 38.5% and 25%, with 25% being the final equity
ownership upon approval of an NDA for DES in the U.S. In addition to our equity ownership, RegeneRx retains a royalty on net sales that varies between
single and low double digits, depending on whether commercial sales are made by ReGenTree or a licensee. In the event ReGenTree is acquired or there
is a change of control that occurs following achievement of an NDA, RegeneRx shall be entitled to a minimum of 40% of all proceeds paid or payable
and will forgo any future royalties. The Company is not required or otherwise obligated to provide financial support to the Joint Venture.

The Joint Venture is responsible for executing all development and commercialization activities under the License Agreement, which activities
will be directed by a joint development committee comprised of representatives of the Company and GtreeBNT. The License Agreement has a term that
extends to the later of the expiration of the last patent covered by the License Agreement or 25 years from the first commercial sale under the License
Agreement.  The  License  Agreement  may  be  earlier  terminated  if  the  Joint  Venture  fails  to  meet  certain  commercialization  milestones,  if  either  party
breaches  the  License  Agreement  and  fails  to  cure  such  breach,  as  a  result  of  government  action  that  limits  the  ability  of  the  Joint  Venture  to
commercialize the product, as a result of a challenge to a licensed patent, following termination of the license between the Company and certain agencies
of the United States federal government, or upon the bankruptcy of either party.

F-15

 
 
 
 
 
 
 
 
 
Under the License Agreement, the Company received $1.0 million in up-front payments and is entitled to receive royalties on the Joint Venture’s
future sales of products. On April 6, 2016, we received $250,000 from ReGenTree and executed an amendment to the license agreement on April 28,
2016. Under the amendment the territorial rights were expanded to include Canada. The Company is accounting for the License Agreement with the Joint
Venture  as  a  revenue  arrangement.  Since  participation  in  the  joint  development  committee  is  required  it  was  deemed  to  be  a  material  promise.
Management  has  concluded  that  the  participation  in  the  joint  development  committee  is  not  distinct  from  other  promised  goods  and  services.  The
Company  assessed  the  license  agreements  in  accordance  with  ASC  606.  The  Company  evaluated  the  promised  goods  and  services  under  the  license
agreements and determined that there was one combined performance obligation representing a series of distinct goods and services including the license
to research, develop and commercialize RGN-259 and participation in the joint development committee. Revenue is being recognized on a straight-line
basis over a period of 30 years, which, in management’s judgment, is the best measure of progress towards satisfying the performance obligation and
represents  the  Company’s  best  estimate  of  the  period  of  the  obligation.  As  of  December  31,  2018  and  2017,  we  have  unearned  revenue  totaling
$1,101,225 and $1,148,544, respectively, pursuant to this agreement. Revenue will be recognized for future royalty payments as they are earned.

7. CONVERTIBLE NOTES

2012 Convertible Note

On  October  19,  2012,  we  completed  a  private  placement  of  convertible  notes  (the  “2012  Notes”)  raising  an  aggregate  of  $300,000  in  gross
proceeds. The 2012 Notes were originally scheduled to mature after twenty-four (24) months from issuance. The 2012 Notes bore interest at a rate of five
percent  (5%)  per  annum  and  were  convertible  into  shares  of  our  common  stock  at  a  conversion  price  of  fifteen  cents  ($0.15)  per  share  (subject  to
adjustment  as  described  in  the  2012  Notes)  at  any  time  prior  to  repayment,  at  the  election  of  the  investors.  In  the  aggregate,  the  2012  Notes  were
convertible into up to 2,000,000 shares of our common stock excluding interest.

At any time prior to maturity of the 2012 Notes, with the consent of the holders of a majority in interest of the 2012 Notes, we could prepay the
outstanding  principal  amount  of  the  2012  Notes  plus  unpaid  accrued  interest  without  penalty.  Upon  the  commission  of  any  act  of  bankruptcy  by  the
Company,  the  execution  by  the  Company  of  a  general  assignment  for  the  benefit  of  creditors,  the  filing  by  or  against  the  Company  of  a  petition  in

days or more, or the appointment of a receiver or trustee to take possession of the property or assets of the Company, the outstanding principal and all
accrued interest on the 2012 Notes would accelerate and automatically become immediately due and payable.

In connection with the issuance of the 2012 Notes, we also issued warrants to each Investor. The warrants were exercisable for an aggregate of
400,000 shares of common stock with an exercise price of fifteen cents ($0.15) per share for a period of five years. The relative fair value of the warrants
issued  was  $27,097,  calculated  using  the  Black-Scholes-Merton  valuation  model  value  of  $0.07  with  an  expected  and  contractual  life  of  5  years,  an
assumed volatility of 74.36%, and a risk-free interest rate of 0.77%. The warrants were recorded as additional paid-in-capital and a discount on the 2012
Notes of $27,097.

respective warrants, are as set forth below:

During 2014, the Company amended the existing October 2012 convertible debt agreement with the holders, solely to extend the due date of the
principal and accrued unpaid until interest October 19, 2017.  No other terms of the original debt were amended or modified, and the holders did not
reduce the borrowed amount or change the interest rate of the debt.  The Company considered the restructuring a troubled debt restructuring as a result of
the Company’s financial condition (see Note 1 discussion of “going concern”).  At the date of the amendment, all existing debt discounts and deferred
financing fees were fully amortized and the amendment did not involve any additional fees paid to the holders or third parties; as such there was no gain
recognized as a result of the amendment. The 2012 Notes matured, and the holders elected to convert the note balances of $300,000 and accrued interest
of approximately $76,000 into common stock and also exercised the associated warrants in October 2017.

2013 Convertible Notes

On March 29, 2013, we completed a private placement of convertible notes (the “March 2013 Notes”) raising an aggregate of $225,000 in gross
proceeds. The March 2013 Notes bore interest at a rate of five percent (5%) per annum, matured sixty (60) months after their date of issuance and were
convertible into shares of our common stock at a conversion price of six cents ($0.06) per share (subject to adjustment as described in the March 2013
Notes)  at  any  time  prior  to  repayment,  at  the  election  of  the  investors.  In  the  aggregate,  the  March  2013  Notes  were  initially  convertible  into  up  to
3,750,000 shares of our common stock.

At any time prior to maturity of the March 2013 Notes, with the consent of the holders of a majority in interest of the March 2013 Notes, we
could prepay the outstanding principal amount of the March 2013 Notes plus unpaid accrued interest without penalty. Upon the commission of any act of
bankruptcy by the Company, the execution by the Company of a general assignment for the benefit of creditors, the filing by or against the Company of a
petition in bankruptcy or any petition for relief under the Federal bankruptcy act or the continuation of such petition without dismissal for a period of
ninety (90) days or more, or the appointment of a receiver or trustee to take possession of the property or assets of the Company, the outstanding principal
and all accrued interest on the March 2013 Notes would accelerate and automatically become immediately due and payable.

The Company evaluated the terms of the March 2013 Notes which contained a down round provision under which the conversion price could be
decreased as a result of future equity offerings, as defined in the March 2013 Notes.  The adjustment would reduce the conversion price of the March
2013  Notes  to  be  equivalent  to  that  of  the  newly  issued  stock  or  stock-related  instruments.   As  a  result,  the  Company  concluded  that  the  conversion
feature  represented  an  embedded  conversion  feature  for  accounting  purposes  and  should  be  recognized  as  a  derivative  liability,  requiring  a  mark-to-
market adjustment at the end of each reporting period until the related March 2013 Notes have been settled prior to the adoption of ASU 2017-11. The
bifurcated liability of $225,000 was recorded on the date of issuance which resulted in a residual debt value of $0.  The discount related to the embedded
feature was accreted as an addition to the debt through the maturity of the notes. The March 2013 Notes matured, and the holders elected to convert the
note balances of $225,000 and accrued interest of approximately $57,000 into common stock in March 2018.

On  July  5,  2013,  we  completed  a  private  placement  of  convertible  notes  (the  “July  2013  Notes”)  raising  an  aggregate  of  $100,000  in  gross
proceeds. The July 2013 Notes bore interest at a rate of five percent (5%) per annum, matured sixty (60) months after their date of issuance and were
convertible into shares of our common stock at a conversion price of six cents ($0.06) per share (subject to adjustment as described in the July 2013
Notes)  at  any  time  prior  to  repayment,  at  the  election  of  the  investors.  In  the  aggregate,  the  July  2013  Notes  were  initially  convertible  into  up  to
1,666,667 shares of our common stock.

2014 Convertible Notes

On January 7, 2014, we completed a private placement of convertible notes raising an aggregate of $55,000 in gross proceeds (the “January
2014 Notes”).   The January 2014 Notes bear interest at a rate of 5% per annum, mature sixty (60) months after their date of issuance and are convertible

Common Stock. In March, July and September of 2018, the March 2013, July 2013 and September 2013 Notes matured, and the holders elected
to convert the note balances and accrued interest into common stock. As a result, we issued 4,700,520, 2,089,120 and 6,706,076 shares of common stock,
respectively. (see Note 7)

On  March  2,  2018,  we  entered  into  the  Reprice  Agreement  with  Sabby  Healthcare  Master  Fund,  Ltd.,  and  Sabby  Volatility  Warrant  Master
Fund, Ltd. (collectively, “Sabby”). In connection with that certain securities purchase agreement between the Company and Sabby dated June 27, 2016
(the “Purchase Agreement”) we also issued to Sabby warrants to purchase 5,147,059 shares of common stock (the “Warrant Shares”) at an exercise price
of  $0.51  per  share  (the  “Sabby  Warrants”).  Under  the  terms  of  the  Reprice  Agreement,  in  consideration  of  Sabby  exercising  in  full  all  of  the  Sabby
Warrants  (the  “Warrant  Exercise”),  the  exercise  price  per  share  of  the  Sabby  Warrants  was  reduced  to  $0.20  per  share.  In  addition,  and  as  further
consideration, we issued to Sabby warrants to purchase up to 3,860,294 shares of common stock at an exercise price of $0.2301 per share, the closing bid
price for the Company’s Common Stock on February 28, 2018 (the “New Warrants”). We received gross proceeds of approximately $1,029,000 from the
warrant reprice transaction.

The Reprice Agreement was accounted for as an inducement and consequently, we recognized a non-operating expense of $582,904 equal to the
fair  value  of  the  New  Warrants  calculated  using  a  customized  Monte  Carlo  simulation.  The  repricing  of  the  Warrant  Shares  did  not  result  in  any
incremental fair value and consequently did not result in any additional expense.

In conjunction with the Reprice Agreement we incurred $101,110 of expenses comprised of: (i) 102,947 warrants valued at $15,545 issued to an
outside third party as a fee for the transaction and (ii) $85,565 of expenses for professional fees. Such expenses were netted against the proceeds from the
transaction. The warrants contained the same terms and conditions as the New Warrants and were valued using the Black-Scholes model.

Registration Rights Agreements. In connection with the sale of certain equity instruments, we have entered into Registration Rights Agreements.
Generally,  these  Agreements  required  us  to  file  registration  statements  with  the  Securities  and  Exchange  Commission  to  register  common  shares  to
permit re-sale of common shares previously sold under an exemption from registration or to register common shares that may be issued on exercise of
outstanding warrants.

The Registration Rights Agreements usually require us to pay penalties for any failure or time delay in filing or maintaining the effectiveness of
the  required  registration  statements.  These  penalties  are  usually  expressed  as  a  fixed  percentage,  per  month,  of  the  original  amount  we  received  on
issuance of the common shares, options or warrants. While to date we have not incurred any penalties under these agreements, if a penalty is determined
to be probable we would recognize the amount as a contingent liability and not as a derivative instrument.

Share-Based Compensation.  We  recognized  $276,129  and  $271,377  in  stock-based  compensation  expense  for  the  years  ended  December  31,
2018 and 2017, respectively. We expect to recognize the compensation cost related to non-vested options as of December 31, 2018 of $273,000 over the
weighted average remaining recognition period of 1.23 years.

Stock  Option  and  Incentive  Plans.  On  June  13,  2018,  at  our  Annual  Meeting  of  Stockholders,  our  stockholders  approved  the  2018  Equity
Incentive Plan (the “2018 Plan”). The terms of the 2018 Plan provide for the discretionary grant of incentive stock options, nonstatutory stock options,
stock  appreciation  rights,  restricted  stock  awards,  restricted  stock  unit  awards,  performance  stock  awards,  other  stock  awards  and  performance  cash
awards  to  our  employees,  directors  and  consultants.  The  total  number  of  shares  of  our  common  stock  reserved  for  issuance  under  the  2018  Plan  is
initially 5,000,000 shares of common stock with additional shares being available for grant under the plan annually in an amount equal to 2% of the then
outstanding shares of common stock on July 1 of each calendar year.

We  have  previously  adopted  two  equity  incentive  plans,  known  as  the  2000  Equity  Incentive  Plan,  or  the  2000  Plan,  and  the  2010  Equity
Incentive Plan, or the 2010 Plan. Both the 2000 Plan and the 2010 Plan have a term of ten years, with the 2000 Plan already expired and the 2010 Plan
scheduled  to  expire  in  July  2020.  No  further  awards  may  be  granted  under  the  2010  Plan  with  the  approval  of  the  2018  Plan.  All  outstanding  option
awards granted under the 2000 Plan and the 2010 Plan will continue to be subject to the terms and conditions as set forth in the agreements evidencing
such option awards and the terms of the 2000 Plan and the 2010 Plan. Shares remaining available for issuance under the shares reserve of the 2010 Plan
will  not  be  subject  to  future  awards  under  the  2018  Plan,  and  shares  subject  to  outstanding  awards  under  the  2000  Plan  and  the  2010  Plan  that  are
terminated or forfeited in the future will not be subject to future awards under the 2018 Plan.

The  following  summarizes  share-based  compensation  expense  for  the  years  ended  December  31,  2018  and  2017,  which  was  allocated  as

Determining the Fair Value of Options. We use the Black-Scholes valuation model to estimate the fair value of options granted. Black-Scholes
considers  a  number  of  factors,  including  the  market  price  and  volatility  of  our  common  stock.  We  used  the  following  forward-looking  range  of
assumptions to value each stock option granted to employees, directors and consultants during the years ended December 31, 2018 and 2017:

Dividend yield
Risk-free rate of return
Expected life in years
Volatility
Forfeiture rate

5.88 

89%   
2.6%   

0.0%
1.73%
5.88

2.6%

Our dividend yield assumption is based on the fact that we have never paid cash dividends and do not anticipate paying cash dividends in the
foreseeable  future.  Our  risk-free  interest  rate  assumption  is  based  on  yields  of  U.S.  Treasury  notes  in  effect  at  the  date  of  grant.  Our  expected  life
represents  the  period  of  time  that  options  granted  are  expected  to  be  outstanding  and  is  calculated  in  accordance  with  the  Securities  and  Exchange
Commission (“SEC”) guidance provided in the SEC’s Staff Accounting Bulletin (“SAB”) 107 and SAB 110, using a “simplified” method. The Company
has  used  the  simplified  method  and  will  continue  to  use  the  simplified  method  as  it  does  not  have  sufficient  historical  exercise  data  to  provide  a
reasonable basis upon which to estimate an expected term. Our volatility assumption is based on reviews of the historical volatility of our common stock.
Using Black-Scholes and these factors, the weighted average fair value of stock options granted to employees and directors was $0.16 and $0.21 for the
years  ended  December  31,  2018  and  2017,  respectively.  We  do  not  record  tax-related  effects  on  stock-based  compensation  given  our  historical  and
anticipated operating experience and offsetting changes in our valuation allowance which fully reserves against potential deferred tax assets.

At December 31, 2018, we had net operating loss carryforwards for income tax purposes of approximately $49.1 million, which are available to
offset  future  federal  and  state  taxable  income,  if  any,  and,  research  and  experimental  tax  credit  carryforwards  of  approximately  $2.3  million.
Approximately $47.9 million of the net operating loss carryforward, generated prior to 2018, expires in increments through 2037, while the carryforward
generated in 2018 does not expire.

Section 382 of the Internal Revenue Code imposes substantial restrictions on the utilization of net operating losses and tax credits in the event of
a corporation’s ownership change. During 2009, the Company completed a preliminary study to compute any limits on the net operating losses and credit
carryforwards  for  purposes  of  Section  382.  It  was  determined  that  the  Company  experienced  a  cumulative  change  in  ownership,  as  defined  by  the
regulations,  in  2002.  This  change  in  ownership  triggers  an  annual  limitation  on  the  Company’s  ability  to  utilize  certain  U.S.  federal  and  state  net
operating  loss  carryforwards  and  research  tax  credit  carryforwards,  resulting  in  the  potential  loss  of  approximately  $9.8  million  of  net  operating  loss
carryforwards and $0.2 million in research credit carryforwards. The Company has reduced the deferred tax assets associated with these carryforwards in
its balance sheets. The Company believes that the future use of net operating losses and tax credits presented above may be further reduced as a result of
additional ownership changes subsequent to 2009.

The provision for income taxes on earnings subject to income taxes differs from the statutory federal rate for the years ended December 31,

2018 and 2017, due to the following:

US Federal statutory rate
State income tax, net of Federal benefit
Foreign tax
Change in fair value of derivative liabilities
Share-based compensation
Permanent differences and other
Research and experimentation credits
Foreign tax credits
Changes in federal tax rate due to Tax Cuts and Jobs Act
Change in valuation allowance

The most significant impact on our effective tax rate in 2017 was the revaluation of our deferred tax assets and liabilities at the lower 21% U.S.
corporate tax rate, as proscribed by the Tax Cuts and Jobs Act, which was enacted on December 22, 2017 and lowered the U.S. corporate tax rate from
35% to 21% beginning in 2018.

As  discussed  in  Note  2,  we  recognize  the  effect  of  income  tax  positions  only  if  those  positions  more  likely  than  not  of  being  sustained.  At
December 31, 2018 and 2017, we had no gross unrecognized tax benefits. We do not expect any significant changes in unrecognized tax benefits over the
next 12 months. In addition, we did not recognize any interest or penalties related to uncertain tax positions at December 31, 2018 and 2017.

The  2008  through  2018  tax  years  generally  remain  subject  to  examination  by  federal  and  most  state  tax  authorities.  In  addition,  we  would

remain open to examination for earlier years if we were to utilize net operating losses or tax credit carryforwards that originated prior to 2012. 

10. COMMITMENTS

Lease. In February 2017, we amended our office lease agreement and the term was extended through July 2020. During the extended term our

rental payments will average approximately $4,000 per month.

The future minimum rent payments as of December 31, are as follows:

2019
2020

48,101 
28,850

Employment Continuity Agreements. We have entered into employment contracts with our executive officers which provide for severance if the
executive is dismissed without cause or under certain circumstances after a change of control in our ownership. At December 31, 2018, these obligations,
if triggered, could amount to a maximum of approximately $170,000.

Convertible Debt Placement

On  February  27,  2019  we  sold  a  series  of  convertible  promissory  notes  to  management,  the  Company’s  Board  of  Directors  and  accredited
investors including Essetifin S.p.A., our largest shareholder. The sale of the notes will result in gross proceeds to the Company of $1,300,000 over two
closings. The first closing in the amount of $650,000 occurred on February 27th and the second closing, also in the amount of $650,000 will occur within
three  days  of  the  Company  providing  notice  of  the  enrolment  of  the  first  patent  in  the  ARISE-3  clinical  trial  in  DES  sponsored  by  ReGenTree.
ReGenTree has informed us that they now expect the ARISE-3 clinical trial to occur in the second quarter of 2019. The notes contain a $0.12 conversion
price  and  the  purchasers  also  received  a  warrant  exercisable  at  $0.18  to  purchase  additional  shares  of  common  stock  equal  to  75%  of  the  number  of
shares into which each note is initially convertible. At present, with the receipt of the sale proceeds from the first closing coupled with the anticipated
proceeds from the second closing, we will have sufficient cash to fund planned operations through the first quarter of 2020.

REGENERX BIOPHARMACEUTICALS, INC.

2018 EQUITY INCENTIVE PLAN

ADOPTED BY THE BOARD OF DIRECTORS EFFECTIVE AS OF &
APPROVED BY THE STOCKHOLDERS: JUNE 13, 2018

TERMINATION DATE: JUNE 13, 2028

1. GENERAL.

(a) Eligible Award Recipients. The persons eligible to receive Awards are Employees, Directors and Consultants.

(b) Available Awards. The Plan provides for the grant of the following Awards: (i) Incentive Stock Options, (ii) Nonstatutory Stock Options, (iii) Stock
Appreciation Rights, (iv) Restricted Stock Awards, (v) Restricted Stock Unit Awards, (vi) Performance Stock Awards, (vii) Performance Cash Awards, and
(viii) Other Stock Awards.

(c) Purpose. The Company, by means of the Plan, seeks to secure and retain the services of the group of persons eligible to receive Awards as set forth
in Section 1(a), to provide incentives for such persons to exert maximum efforts for the success of the Company and any Affiliate and to provide a means by
which such eligible recipients may be given an opportunity to benefit from increases in value of the Common Stock through the granting of Awards.

2. ADMINISTRATION.

(a) Administration by Board. The Board shall administer the Plan unless and until the Board delegates administration of the Plan to a Committee or

Committees, as provided in Section 2(c).

(b) Powers of Board. The Board shall have the power, subject to, and within the limitations of, the express provisions of the Plan:

(i) To determine from time to time (A) which of the persons eligible under the Plan shall be granted Awards; (B) when and how each Award shall
be  granted;  (C)  what  type  or  combination  of  types  of  Award  shall  be  granted;  (D)  the  provisions  of  each Award  granted  (which  need  not  be  identical),
including  the  time  or  times  when  a  person  shall  be  permitted  to  receive  cash  or  Common  Stock  pursuant  to  a  Stock  Award;  (E)  the  number  of  shares  of
Common Stock with respect to which a Stock Award shall be granted to each such person; and (F) the Fair Market Value applicable to a Stock Award.

(ii)  To  construe  and  interpret  the  Plan  and  Awards  granted  under  it,  and  to  establish,  amend  and  revoke  rules  and  regulations  for  its
administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan or in any Stock Award Agreement or in
the written terms of a Performance Cash Award, in a manner and to the extent it shall deem necessary or expedient to make the Plan or Award fully effective.

(iii) To settle all controversies regarding the Plan and Awards granted under it.

(iv)  To  accelerate  the  time  at  which  an  Award  may  first  be  exercised  or  the  time  during  which  an  Award  or  any  part  thereof  will  vest  in
accordance with the Plan, notwithstanding the provisions in the Award stating the time at which it may first be exercised or the time during which it will vest.

(v) To suspend or terminate the Plan at any time. Suspension or termination of the Plan shall not impair rights and obligations under any Award

granted while the Plan is in effect except with the written consent of the affected Participant.

(vi)  To  amend  the  Plan  in  any  respect  the  Board  deems  necessary  or  advisable.  However,  except  as  provided  in  Section  9(a)  relating  to
Capitalization Adjustments, to the extent required by applicable law or listing requirements, stockholder approval shall be required for any amendment of the
Plan that either (A) materially increases the number of shares of Common Stock available for issuance under the Plan, (B) materially expands the class of
individuals eligible to receive Awards under the Plan, (C) materially increases the benefits accruing to Participants under the Plan or materially reduces the
price at which shares of Common Stock may be issued or purchased under the Plan, (D) materially extends the term of the Plan, or (E) expands the types of
Awards available for issuance under the Plan. Except as provided above, rights under any Award granted before amendment of the Plan shall not be impaired
by any amendment of the Plan unless (1) the Company requests the consent of the affected Participant, and (2) such Participant consents in writing.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
(vii) To submit any amendment to the Plan for stockholder approval, including, but not limited to, amendments to the Plan intended to satisfy the
requirements  of  (A)  Section  162(m)  of  the  Code  regarding  the  exclusion  of  performance-based  compensation  from  the  limit  on  corporate  deductibility  of
compensation paid to Covered Employees, (B) Section 422 of the Code regarding incentive stock options or (C) Rule 16b-3.

(viii) To  approve  forms  of  Award  Agreements  for  use  under  the  Plan  and  to  amend  the  terms  of  any  one  or  more  Awards,  including,  but  not
limited to, amendments to provide terms more favorable to the Participant than previously provided in the Award Agreement, subject to any specified limits
in  the  Plan  that  are  not  subject  to  Board  discretion;  provided however,  that  except  with  respect  to  amendments  that  disqualify  or  impair  the  status  of  an
Incentive Stock Option, a Participant’s rights under any Award shall not be impaired by any such amendment unless (A) the Company requests the consent of
the affected Participant, and (B) such Participant consents in writing. Notwithstanding the foregoing, subject to the limitations of applicable law, if any, the
Board may amend the terms of any one or more Awards without the affected Participant’s consent if necessary to maintain the qualified status of the Award as
an Incentive Stock Option or to bring the Award into compliance with Section 409A of the Code.

(ix) Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best interests of the

Company and that are not in conflict with the provisions of the Plan or Awards.

(x)  To  adopt  such  procedures  and  sub-plans  as  are  necessary  or  appropriate  to  permit  participation  in  the  Plan  by  Employees,  Directors  or

Consultants who are foreign nationals or employed outside the United States.

(c) Delegation to Committee.

(i) General. The Board may delegate some or all of the administration of the Plan to a Committee or Committees. If administration of the Plan is
delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that
have been delegated to the Committee, including the power to delegate to a subcommittee of the Committee any of the administrative powers the Committee
is authorized to exercise (and references in this Plan to the Board shall thereafter be to the Committee or subcommittee), subject, however, to such resolutions,
not  inconsistent  with  the  provisions  of  the  Plan,  as  may  be  adopted  from  time  to  time  by  the  Board.  The  Committee  may,  at  any  time,  abolish  the
subcommittee and/or revest in the Committee any powers delegated to the subcommittee. The Board may retain the authority to concurrently administer the
Plan with the Committee and may, at any time, revest in the Board some or all of the powers previously delegated.

(ii)  Section  162(m)  and  Rule  16b-3  Compliance.  The  Committee  may  consist  solely  of  two  or  more  Outside  Directors,  in  accordance  with

Section 162(m) of the Code, and solely of two or more Non-Employee Directors, in accordance with Rule 16b-3.

(d)  Delegation  to  an  Officer.  The  Board  may  delegate  to  one  (1)  or  more  Officers  the  authority  to  do  one  or  both  of  the  following  (i)  designate
Employees  who  are  providing  Continuous  Service  to  the  Company  or  any  of  its  Subsidiaries  who  are  not  Officers  to  be  recipients  of  Options  and  Stock
Appreciation Rights (and, to the extent permitted by applicable law, other Stock Awards) and the terms thereof, and (ii) determine the number of shares of
Common Stock to be subject to such Stock Awards granted to such Employees; provided, however, that the Board resolutions regarding such delegation shall
specify the total number of shares of Common Stock that may be subject to the Stock Awards granted by such Officer and that such Officer may not grant a
Stock Award to himself or herself. Notwithstanding the foregoing, the Board may not delegate authority to an Officer to determine the Fair Market Value
pursuant to Section 13(w)(iii) below.

(e) Effect of Board’s Decision. All determinations, interpretations and constructions made by the Board in good faith shall not be subject to review by

any person and shall be final, binding and conclusive on all persons.

(f) Cancellation and Re-Grant of Stock Awards. Neither the Board nor any Committee shall have the authority to: (i) reduce the exercise price of any
outstanding Options or Stock Appreciation Rights under the Plan, or (ii) cancel any outstanding Options or Stock Appreciation Rights that have an exercise
price or strike price greater than the current Fair Market Value of the Common Stock in exchange for cash or other Stock Awards under the Plan, unless the
stockholders of the Company have approved such an action within twelve (12) months prior to such an event.

3. SHARES SUBJECT TO THE PLAN.

(a) Share Reserve. Subject to Section 9(a) relating to Capitalization Adjustments, the aggregate number of shares of Common Stock that may be issued
pursuant to Stock Awards from and after the Effective Date shall initially be five million (5,000,000) shares and shall increase annually on July 1 for each
year the Plan is in effect starting on July 1, 2019 by the number of shares equal to two percent (2%) of the then issued and outstanding shares of Common
Stock of the Company. For clarity, the Share Reserve in this Section 3(a) is a limitation on the number of shares of the Common Stock that may be issued
pursuant to the Plan and does not limit the granting of Stock Awards except as provided in Section 7(a). Shares may be issued in connection with a merger or
acquisition  as  permitted  by,  as  applicable,  NASDAQ  Listing  Rule  5635(c)  or,  if  applicable,  NYSE  Listed  Company  Manual  Section  303A.08,  AMEX
Company  Guide  Section  711  or  other  applicable  rule,  and  such  issuance  shall  not  reduce  the  number  of  shares  available  for  issuance  under  the  Plan.
Furthermore, if a Stock Award or any portion thereof (i) expires or otherwise terminates without all of the shares covered by such Stock Award having been
issued or (ii) is settled in cash (i.e., the Participant receives cash rather than stock), such expiration, termination or settlement shall not reduce (or otherwise
offset) the number of shares of Common Stock that may be available for issuance under the Plan.

(b) Reversion of Shares to the Share Reserve. If any shares of Common Stock issued pursuant to a Stock Award are forfeited back to the Company
because of the failure to meet a contingency or condition required to vest such shares in the Participant, then the shares that are forfeited shall revert to and
again become available for issuance under the Plan. Any shares reacquired by the Company pursuant to Section 8(g) or as consideration for the exercise of an
Option shall again become available for issuance under the Plan.

(c) Incentive Stock Option Limit. Notwithstanding anything to the contrary in this Section 3 and, subject to the provisions of Section 9(a) relating to
Capitalization  Adjustments,  the  aggregate  maximum  number  of  shares  of  Common  Stock  that  may  be  issued  pursuant  to  the  exercise  of  Incentive  Stock
Options shall initially be five million (5,000,000) shares of Common Stock and then shall be the number of shares of Common Stock reserved for issuance
under the Plan pursuant to Section 3(a) for subsequent years that the Plan is in effect. 

(d) Section 162(m) Limitation on Annual Grants. Subject to the provisions of Section 9(a) relating to Capitalization Adjustments, at such time as the
Company may be subject to the applicable provisions of Section 162(m) of the Code, a maximum of one million (1,000,000) shares of Common Stock subject
to Options, Stock Appreciation Rights and Other Stock Awards whose value is determined by reference to an increase over an exercise or strike price of at
least  one  hundred  percent  (100%)  of  the  Fair  Market  Value  on  the  date  any  such  Stock  Award  is  granted  may  be  granted  to  any  Participant  during  any
calendar  year.  Notwithstanding  the  foregoing,  if  any  additional  Options,  Stock  Appreciation  Rights  or  Other  Stock  Awards  whose  value  is  determined  by
reference to an increase over an exercise or strike price of at least one hundred percent (100%) of the Fair Market Value on the date the Stock Award are
granted  to  any  Participant  during  any  calendar  year,  compensation  attributable  to  the  exercise  of  such  additional  Stock  Awards  shall  not  satisfy  the
requirements  to  be  considered  “qualified  performance-based  compensation”  under  Section  162(m)  of  the  Code  unless  such  additional  Stock  Award  is
approved by the Company’s stockholders.

(e)  Source  of  Shares.  The  stock  issuable  under  the  Plan  shall  be  shares  of  authorized  but  unissued  or  reacquired  Common  Stock,  including  shares

repurchased by the Company on the open market or otherwise.

4. ELIGIBILITY.

(a) Eligibility for Specific Stock Awards. Incentive Stock Options may be granted only to employees of the Company or a “parent corporation” or
“subsidiary corporation” thereof (as such terms are defined in Sections 424(e) and (f) of the Code). Stock Awards other than Incentive Stock Options may be
granted to Employees, Directors and Consultants; provided, however, Nonstatutory Stock Options and SARs may not be granted to Employees, Directors and
Consultants  who  are  providing  Continuous  Service  only  to  any  “parent”  of  the  Company,  as  such  term  is  defined  in  Rule  405  promulgated  under  the
Securities  Act,  unless  the  stock  underlying  such  Stock  Awards  is  treated  as  “service  recipient  stock”  under  Section  409A  of  the  Code  because  the  Stock
Awards are granted pursuant to a corporate transaction (such as a spin off transaction) or unless such Stock Awards comply with the distribution requirements
of Section 409A of the Code.

3

 
 
 
 
 
 
 
 
 
 
 
 
(b) Ten Percent Stockholders. A Ten Percent Stockholder shall not be granted an Incentive Stock Option unless the exercise price of such Option is at
least one hundred ten percent (110%) of the Fair Market Value on the date of grant and the Option is not exercisable after the expiration of five (5) years from
the date of grant.

5. PROVISIONS RELATING TO OPTIONS AND STOCK APPRECIATION RIGHTS. Each Option or SAR shall be in such form and shall contain such terms and conditions
as the Board shall deem appropriate. All Options shall be separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant,
and, if certificates are issued, a separate certificate or certificates shall be issued for shares of Common Stock purchased on exercise of each type of Option. If
an  Option  is  not  specifically  designated  as  an  Incentive  Stock  Option,  then  the  Option  shall  be  a  Nonstatutory  Stock  Option.  The  provisions  of  separate
Options or SARs need not be identical; provided, however, that each Option Agreement or Stock Appreciation Right Agreement shall conform to (through
incorporation of provisions hereof by reference in the applicable Award Agreement or otherwise) the substance of each of the following provisions:

(a) Term. Subject to the provisions of Section 4(b) regarding Ten Percent Stockholders, no Option or SAR shall be exercisable after the expiration of

ten (10) years from the date of its grant or such shorter period specified in the Award Agreement.

(b) Exercise Price. Subject to the provisions of Section 4(b) regarding Ten Percent Stockholders, the exercise price (or strike price) of each Option or
SAR shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option or SAR on the date the Option
or SAR is granted. Notwithstanding the foregoing, an Option or SAR may be granted with an exercise price (or strike price) lower than one hundred percent
(100%)  of  the  Fair  Market  Value  of  the  Common  Stock  subject  to  the  Option  or  SAR  if  such  Option  or  SAR  is  granted  pursuant  to  an  assumption  of  or
substitution  for  another  option  or  stock  appreciation  right  pursuant  to  a  Corporate  Transaction  and  in  a  manner  consistent  with  the  provisions  of
Sections 409A and, if applicable, 424(a) of the Code. Each SAR will be denominated in shares of Common Stock equivalents.

(c)  Purchase  Price  for  Options.  The  purchase  price  of  Common  Stock  acquired  pursuant  to  the  exercise  of  an  Option  shall  be  paid,  to  the  extent
permitted by applicable law and as determined by the Board in its sole discretion, by any combination of the methods of payment set forth below. The Board
shall have the authority to grant Options that do not permit all of the following methods of payment (or otherwise restrict the ability to use certain methods)
and to grant Options that require the consent of the Company to utilize a particular method of payment. The permitted methods of payment are as follows:

(i) by cash, check, bank draft or money order payable to the Company;

(ii) pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of the stock
subject to the Option, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise
price to the Company from the sales proceeds;

(iii) by delivery to the Company (either by actual delivery or attestation) of shares of Common Stock;

(iv) if  the  option  is  a  Nonstatutory  Stock  Option,  by  a  “net  exercise”  arrangement  pursuant  to  which  the  Company  will  reduce  the  number  of
shares of Common Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise
price; provided, however, that the Company shall accept a cash or other payment from the Participant to the extent of any remaining balance of the aggregate
exercise price not satisfied by such reduction in the number of whole shares to be issued; provided, further, that shares of Common Stock will no longer be
subject to an Option and will not be exercisable thereafter to the extent that (A) shares issuable upon exercise are reduced to pay the exercise price pursuant to
the “net exercise,” (B) shares are delivered to the Participant as a result of such exercise, and (C) shares are withheld to satisfy tax withholding obligations; or

(v) in any other form of legal consideration that may be acceptable to the Board.

(d) Exercise and Payment of a SAR. To exercise any outstanding Stock Appreciation Right, the Participant must provide written notice of exercise to
the  Company  in  compliance  with  the  provisions  of  the  Stock  Appreciation  Right  Agreement  evidencing  such  Stock  Appreciation  Right.  The  appreciation
distribution payable on the exercise of a Stock Appreciation Right will be not greater than an amount equal to the excess of (A) the aggregate Fair Market
Value  (on  the  date  of  the  exercise  of  the  Stock  Appreciation  Right)  of  a  number  of  shares  of  Common  Stock  equal  to  the  number  of  Common  Stock
equivalents  in  which  the  Participant  is  vested  under  such  Stock  Appreciation  Right,  and  with  respect  to  which  the  Participant  is  exercising  the  Stock
Appreciation Right on such date, over (B) the strike price that will be determined by the Board at the time of grant of the Stock Appreciation Right. The
appreciation distribution in respect to a Stock Appreciation Right may be paid in Common Stock, in cash, in any combination of the two or in any other form
of consideration, as determined by the Board and contained in the Stock Appreciation Right Agreement evidencing such Stock Appreciation Right.

(e) Transferability of Options and SARs. The Board may, in its sole discretion, impose such limitations on the transferability of Options and SARs as
the Board shall determine. In the absence of such a determination by the Board to the contrary, the following restrictions on the transferability of Options and
SARs shall apply:

(i) Restrictions on Transfer. An Option or SAR shall not be transferable except by will or by the laws of descent and distribution and shall be
exercisable during the lifetime of the Participant only by the Participant; provided, however, that the Board may, in its sole discretion, permit transfer of the
Option or SAR in a manner that is not prohibited by applicable tax and securities laws upon the Participant’s request. Except as explicitly provided herein,
neither an Option nor a SAR may be transferred for consideration.

(ii) Domestic Relations Orders. Notwithstanding the foregoing, an Option or SAR may be transferred pursuant to a domestic relations order;

provided, however, that if an Option is an Incentive Stock Option, such Option may be deemed to be a Nonstatutory Stock Option as a result of such transfer.

(iii)  Beneficiary  Designation.  Notwithstanding  the  foregoing,  the  Participant  may,  by  delivering  written  notice  to  the  Company,  in  a  form
provided by or otherwise satisfactory to the Company, designate a third party who, in the event of the death of the Participant, shall thereafter be entitled to
exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. In the absence of such a designation, the
executor or administrator of the Participant’s estate shall be entitled to exercise the Option or SAR and receive the Common Stock or other consideration
resulting from such exercise.

(f)  Vesting  Generally.  The  total  number  of  shares  of  Common  Stock  subject  to  an  Option  or  SAR  may  vest  and  therefore  become  exercisable  in
periodic installments that may or may not be equal. The Option or SAR may be subject to such other terms and conditions on the time or times when it may
or may not be exercised (which may be based on the satisfaction of Performance Goals or other criteria) as the Board may deem appropriate. The vesting
provisions of individual Options or SARs may vary. The provisions of this Section 5(f) are subject to any Option or SAR provisions governing the minimum
number of shares of Common Stock as to which an Option or SAR may be exercised.

(g) Termination of Continuous Service. Except as otherwise provided in the applicable Award Agreement or other agreement between the Participant
and the Company, if a Participant’s Continuous Service terminates (other than for Cause or upon the Participant’s death or Disability), the Participant may
exercise his or her Option or SAR (to the extent that the Participant was entitled to exercise such Award as of the date of termination of Continuous Service)
but only within such period of time ending on the earlier of (i) the date three (3) months following the termination of the Participant’s Continuous Service (or
such longer or shorter period specified in the applicable Award Agreement), or (ii) the expiration of the term of the Option or SAR as set forth in the Award
Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR within the time specified herein or in the
Award Agreement (as applicable), the Option or SAR shall terminate.

(h) Extension of Termination Date. If the exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than
for Cause or upon the Participant’s death or Disability) would be prohibited at any time solely because the issuance of shares of Common Stock would violate
the registration requirements under the Securities Act, then the Option or SAR shall terminate on the earlier of (i) the expiration of a total period of three
(3) months (that need not be consecutive) after the termination of the Participant’s Continuous Service during which the exercise of the Option or SAR would
not be in violation of such registration requirements, or (ii) the expiration of the term of the Option or SAR as set forth in the applicable Award Agreement. In
addition,  unless  otherwise  provided  in  a  Participant’s  Award  Agreement,  if  the  sale  of  any  Common  Stock  received  upon  exercise  of  an  Option  or  SAR
following the termination of the Participant’s Continuous Service (other than for Cause) would violate the Company’s insider trading policy, then the Option
or  SAR  shall  terminate  on  the  earlier  of  (i)  the  expiration  of  a  period  equal  to  the  applicable  post-termination  exercise  period  after  the  termination  of  the
Participant’s Continuous Service during which the sale of the Common Stock received upon exercise of the Option or SAR would not be in violation of the
Company’s insider trading policy, or (ii) the expiration of the term of the Option or SAR as set forth in the applicable Award Agreement.

5

 
 
 
 
 
 
 
 
 
 
 
(i) Disability of Participant. Except  as  otherwise  provided  in  the  applicable  Award  Agreement  or  other  agreement  between  the  Participant  and  the
Company, if a Participant’s Continuous Service terminates as a result of the Participant’s Disability, the Participant may exercise his or her Option or SAR (to
the extent that the Participant was entitled to exercise such Option or SAR as of the date of termination of Continuous Service), but only within such period of
time ending on the earlier of (i) the date twelve (12) months following such termination of Continuous Service (or such longer or shorter period specified in
the  Award  Agreement),  or  (ii)  the  expiration  of  the  term  of  the  Option  or  SAR  as  set  forth  in  the  Award  Agreement.  If,  after  termination  of  Continuous
Service, the Participant does not exercise his or her Option or SAR within the time specified herein or in the Award Agreement (as applicable), the Option or
SAR (as applicable) shall terminate.

(j)  Death  of  Participant.  Except  as  otherwise  provided  in  the  applicable  Award  Agreement  or  other  agreement  between  the  Participant  and  the
Company,  if  (i)  a  Participant’s  Continuous  Service  terminates  as  a  result  of  the  Participant’s  death,  or  (ii)  the  Participant  dies  within  the  period  (if  any)
specified  in  the  Award  Agreement  for  exercisability  after  the  termination  of  the  Participant’s  Continuous  Service  (for  a  reason  other  than  death),  then  the
Option or SAR may be exercised (to the extent the Participant was entitled to exercise such Option or SAR as of the date of death) by the Participant’s estate,
by a person who acquired the right to exercise the Option or SAR by bequest or inheritance or by a person designated to exercise the Option or SAR upon the
Participant’s death, but only within the period ending on the earlier of (i) the date eighteen (18) months following the date of death (or such longer or shorter
period  specified  in  the  Award  Agreement),  or  (ii)  the  expiration  of  the  term  of  such  Option  or  SAR  as  set  forth  in  the  Award  Agreement.  If,  after  the
Participant’s death, the Option or SAR is not exercised within the time specified herein or in the Award Agreement (as applicable), the Option or SAR shall
terminate.

(k) Termination for Cause. Except as explicitly provided otherwise in a Participant’s Award Agreement or other individual written agreement between
the  Company  or  any  Affiliate  and  the  Participant,  if  a  Participant’s  Continuous  Service  is  terminated  for  Cause,  the  Option  or  SAR  shall  terminate
immediately  upon  such  Participant’s  termination  of  Continuous  Service,  and  the  Participant  shall  be  prohibited  from  exercising  his  or  her  Option  or  SAR
from and after the time of such termination of Continuous Service.

(l) Non-Exempt Employees. No Option or SAR, whether or not vested, granted to an Employee who is a non-exempt employee for purposes of the
Fair Labor Standards Act of 1938, as amended, shall be first exercisable for any shares of Common Stock until at least six months following the date of grant
of  the  Option  or  SAR.  Notwithstanding  the  foregoing,  consistent  with  the  provisions  of  the  Worker  Economic  Opportunity  Act,  (i)  in  the  event  of  the
Participant’s death or Disability, (ii) upon a Corporate Transaction in which such Option or SAR is not assumed, continued, or substituted, (iii) upon a Change
in Control, or (iv) upon the Participant’s retirement (as such term may be defined in the Participant’s Award Agreement or in another applicable agreement or
in accordance with the Company’s then current employment policies and guidelines), any such vested Options and SARs may be exercised earlier than six
months following the date of grant. The foregoing provision is intended to operate so that any income derived by a non-exempt employee in connection with
the exercise or vesting of an Option or SAR will be exempt from his or her regular rate of pay.

6. PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS AND SARS.

(a) Restricted Stock Awards. Each Restricted Stock Award Agreement shall be in such form and shall contain such terms and conditions as the Board
shall deem appropriate. To the extent consistent with the Company’s Bylaws, at the Board’s election, shares of Common Stock may be (i) held in book entry
form  subject  to  the  Company’s  instructions  until  any  restrictions  relating  to  the  Restricted  Stock  Award  lapse;  or  (ii)  evidenced  by  a  certificate,  which
certificate shall be held in such form and manner as determined by the Board. The terms and conditions of Restricted Stock Award Agreements may change
from time to time, and the terms and conditions of separate Restricted Stock Award Agreements need not be identical; provided, however, that each Restricted
Stock Award Agreement shall conform to (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of
the following provisions:

(i) Consideration. A Restricted Stock Award may be awarded in consideration for (A) cash, check, bank draft or money order payable to the
Company, (B) past services to the Company or an Affiliate, or (C) any other form of legal consideration (including future services) that may be acceptable to
the Board, in its sole discretion, and permissible under applicable law.

(ii) Vesting. Shares  of  Common  Stock  awarded  under  the  Restricted  Stock  Award  Agreement  may  be  subject  to  forfeiture  to  the  Company  in

accordance with a vesting schedule to be determined by the Board.

6

 
 
 
 
 
 
 
 
 
 
 
 
(iii) Termination of Participant’s Continuous Service. If a Participant’s Continuous Service terminates, the Company may receive through a
forfeiture condition or a repurchase right any or all of the shares of Common Stock held by the Participant that have not vested as of the date of termination of
Continuous Service under the terms of the Restricted Stock Award Agreement.

(iv)  Transferability.  Rights  to  acquire  shares  of  Common  Stock  under  the  Restricted  Stock  Award  Agreement  shall  be  transferable  by  the
Participant only upon such terms and conditions as are set forth in the Restricted Stock Award Agreement, as the Board shall determine in its sole discretion,
so long as Common Stock awarded under the Restricted Stock Award Agreement remains subject to the terms of the Restricted Stock Award Agreement.

(v) Dividends. A Restricted Stock Award Agreement may provide that any dividends paid on Restricted Stock will be subject to the same vesting

and forfeiture restrictions as apply to the shares subject to the Restricted Stock Award to which they relate.

(b) Restricted Stock Unit Awards. Each Restricted Stock Unit Award Agreement shall be in such form and shall contain such terms and conditions as
the Board shall deem appropriate. The terms and conditions of Restricted Stock Unit Award Agreements may change from time to time, and the terms and
conditions of separate Restricted Stock Unit Award Agreements need not be identical; provided, however, that each Restricted Stock Unit Award Agreement
shall  conform  to  (through  incorporation  of  the  provisions  hereof  by  reference  in  the  Agreement  or  otherwise)  the  substance  of  each  of  the  following
provisions:

(i) Consideration. At the time of grant of a Restricted Stock Unit Award, the Board will determine the consideration, if any, to be paid by the
Participant upon delivery of each share of Common Stock subject to the Restricted Stock Unit Award. The consideration to be paid (if any) by the Participant
for  each  share  of  Common  Stock  subject  to  a  Restricted  Stock  Unit  Award  may  be  paid  in  any  form  of  legal  consideration  that  may  be  acceptable  to  the
Board, in its sole discretion, and permissible under applicable law.

(ii) Vesting. At the time of the grant of a Restricted Stock Unit Award, the Board may impose such restrictions on or conditions to the vesting of

the Restricted Stock Unit Award as it, in its sole discretion, deems appropriate.

(iii) Payment. A Restricted Stock Unit Award may be settled by the delivery of shares of Common Stock, their cash equivalent, any combination

thereof or in any other form of consideration, as determined by the Board and contained in the Restricted Stock Unit Award Agreement.

(iv) Additional Restrictions. At the time of the grant of a Restricted Stock Unit Award, the Board, as it deems appropriate, may impose such
restrictions or conditions that delay the delivery of the shares of Common Stock (or their cash equivalent) subject to a Restricted Stock Unit Award to a time
after the vesting of such Restricted Stock Unit Award.

(v) Dividend Equivalents. Dividend  equivalents  may  be  credited  in  respect  of  shares  of  Common  Stock  covered  by  a  Restricted  Stock  Unit
Award,  as  determined  by  the  Board  and  contained  in  the  Restricted  Stock  Unit  Award  Agreement.  At  the  sole  discretion  of  the  Board,  such  dividend
equivalents may be converted into additional shares of Common Stock covered by the Restricted Stock Unit Award in such manner as determined by the
Board. Any additional shares covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents will be subject to all of the same
terms and conditions of the underlying Restricted Stock Unit Award Agreement to which they relate.

(vi) Termination of Participant’s Continuous Service. Except as otherwise provided in the applicable Restricted Stock Unit Award Agreement,

such portion of the Restricted Stock Unit Award that has not vested will be forfeited upon the Participant’s termination of Continuous Service.

(c) Performance Awards.

(i) Performance Stock Awards. A Performance Stock Award is a Stock Award that may vest or may be exercised contingent upon the attainment
during a Performance Period of certain Performance Goals. A Performance Stock Award may, but need not, require the completion of a specified period of
Continuous  Service.  The  length  of  any  Performance  Period,  the  Performance  Goals  to  be  achieved  during  the  Performance  Period,  and  the  measure  of
whether  and  to  what  degree  such  Performance  Goals  have  been  attained  shall  be  conclusively  determined  by  the  Committee,  in  its  sole  discretion.  The
maximum number of shares covered by an Award that may be granted to any Participant in a calendar year attributable to Stock Awards described in this
Section 6(c)(i) (whether the grant, vesting or exercise is contingent upon the attainment during a Performance Period of the Performance Goals) shall not
exceed one million (1,000,000) shares of Common Stock. The Board may provide for or, subject to such terms and conditions as the Board may specify, may
permit a Participant to elect for, the payment of any Performance Stock Award to be deferred to a specified date or event. In addition, to the extent permitted
by applicable law and the applicable Award Agreement, the Board may determine that cash may be used in payment of Performance Stock Awards.

7

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
(ii)  Performance  Cash  Awards.  A  Performance  Cash  Award  is  a  cash  award  that  may  be  paid  contingent  upon  the  attainment  during  a
Performance Period of certain Performance Goals. A Performance Cash Award may also require the completion of a specified period of Continuous Service.
At the time of grant of a Performance Cash Award, the length of any Performance Period, the Performance Goals to be achieved during the Performance
Period, and the measure of whether and to what degree such Performance Goals have been attained shall be conclusively determined by the Committee, in its
sole discretion. In any calendar year, the Committee may not grant a Performance Cash Award that has a maximum value that may be paid to any Participant
in excess of five hundred thousand dollars ($500,000). The Board may provide for or, subject to such terms and conditions as the Board may specify, may
permit a Participant to elect for, the payment of any Performance Cash Award to be deferred to a specified date or event. The Committee may specify the
form  of  payment  of  Performance  Cash  Awards,  which  may  be  cash  or  other  property,  or  may  provide  for  a  Participant  to  have  the  option  for  his  or  her
Performance Cash Award, or such portion thereof as the Board may specify, to be paid in whole or in part in cash or other property.

(iii) Board Discretion.  The  Board  retains  the  discretion  to  reduce  or  eliminate  the  compensation  or  economic  benefit  due  upon  attainment  of

Performance Goals and to define the manner of calculating the Performance Criteria it selects to use for a Performance Period.

(iv) Section 162(m) Compliance. Unless otherwise permitted in compliance with the requirements of Section 162(m) of the Code with respect to
an Award intended to qualify as “performance-based compensation” thereunder, the Committee shall establish the Performance Goals applicable to, and the
formula  for  calculating  the  amount  payable  under,  the  Award  no  later  than  the  earlier  of  (a)  the  date  ninety  (90)  days  after  the  commencement  of  the
applicable Performance Period, or (b) the date on which twenty-five percent (25%) of the Performance Period has elapsed, and in either event at a time when
the achievement of the applicable Performance Goals remains substantially uncertain. Prior to the payment of any compensation under an Award intended to
qualify as “performance-based compensation” under Section 162(m) of the Code, the Committee shall certify the extent to which any Performance Goals and
any  other  material  terms  under  such  Award  have  been  satisfied  (other  than  in  cases  where  such  relate  solely  to  the  increase  in  the  value  of  the  Common
Stock).  Notwithstanding  satisfaction  of  any  completion  of  any  Performance  Goals,  to  the  extent  specified  at  the  time  of  grant  of  an  Award  to  “covered
employees”  within  the  meaning  of  Section  162(m)  of  the  Code,  the  number  of  shares  of  Common  Stock,  Options,  cash  or  other  benefits  granted,  issued,
retainable and/or vested under an Award on account of satisfaction of such Performance Goals may be reduced by the Committee on the basis of such further
considerations as the Committee, in its sole discretion, shall determine.

(d) Other Stock Awards. Other forms of Stock Awards valued in whole or in part by reference to, or otherwise based on, Common Stock, including
the appreciation in value thereof (e.g., options or stock rights with an exercise price or strike price less than 100% of the Fair Market Value of the Common
Stock  at  the  time  of  grant)  may  be  granted  either  alone  or  in  addition  to  Stock  Awards  provided  for  under  Section  5  and  the  preceding  provisions  of  this
Section 6. Subject to the provisions of the Plan, the Board shall have sole and complete authority to determine the persons to whom and the time or times at
which such Other Stock Awards will be granted, the number of shares of Common Stock (or the cash equivalent thereof) to be granted pursuant to such Other
Stock Awards and all other terms and conditions of such Other Stock Awards.

7. COVENANTS OF THE COMPANY.

(a) Availability of Shares. During the terms of the Stock Awards, the Company shall keep available at all times the number of shares of Common Stock

reasonably required to satisfy such Stock Awards.

(b) Securities Law Compliance. The Company shall seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such
authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise of the Stock Awards; provided, however, that
this  undertaking  shall  not  require  the  Company  to  register  under  the  Securities  Act  the  Plan,  any  Stock  Award  or  any  Common  Stock  issued  or  issuable
pursuant to any such Stock Award. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority
that counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company shall be relieved from any
liability for failure to issue and sell Common Stock upon exercise of such Stock Awards unless and until such authority is obtained. A Participant shall not be
eligible  for  the  grant  of  a  Stock  Award  or  the  subsequent  issuance  of  Common  Stock  pursuant  to  the  Stock  Award  if  such  grant  or  issuance  would  be  in
violation of any applicable securities law.

8

 
 
 
 
 
 
 
 
 
 
 
(c) No Obligation to Notify or Minimize Taxes. The Company shall have no duty or obligation to any Participant to advise such holder as to the time
or manner of exercising such Stock Award. Furthermore, the Company shall have no duty or obligation to warn or otherwise advise such holder of a pending
termination or expiration of a Stock Award or a possible period in which the Stock Award may not be exercised. The Company has no duty or obligation to
minimize the tax consequences of a Stock Award to the holder of such Stock Award.

8. MISCELLANEOUS.

(a) Use of Proceeds from Sales of Common Stock. Proceeds  from  the  sale  of  shares  of  Common  Stock  pursuant  to  Stock  Awards  shall  constitute

general funds of the Company.

(b)  Corporate  Action  Constituting  Grant  of  Stock  Awards.  Corporate  action  constituting  a  grant  by  the  Company  of  a  Stock  Award  to  any
Participant shall be deemed completed as of the date of such corporate action, unless otherwise determined by the Board, regardless of when the instrument,
certificate, or letter evidencing the Stock Award is communicated to, or actually received or accepted by, the Participant.

(c) Stockholder Rights.  No  Participant  shall  be  deemed  to  be  the  holder  of,  or  to  have  any  of  the  rights  of  a  holder  with  respect  to,  any  shares  of
Common Stock subject to such Stock Award unless and until (i) such Participant has satisfied all requirements for exercise of the Stock Award pursuant to its
terms, if applicable, and (ii) the issuance of the Common Stock subject to such Stock Award has been entered into the books and records of the Company.

(d)  No  Employment  or  Other  Service  Rights.  Nothing  in  the  Plan,  any  Award  Agreement  or  any  other  instrument  executed  thereunder  or  in
connection  with  any  Award  granted  pursuant  thereto  shall  confer  upon  any  Participant  any  right  to  continue  to  serve  the  Company  or  an  Affiliate  in  the
capacity in effect at the time the Award was granted or shall affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee
with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or
an Affiliate, or (iii) the service of a Director pursuant to the Bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the
state in which the Company or the Affiliate is incorporated, as the case may be.

(e) Incentive Stock Option $100,000 Limitation. To the extent that the aggregate Fair Market Value (determined at the time of grant) of Common
Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the
Company and any Affiliates) exceeds one hundred thousand dollars ($100,000), the Options or portions thereof that exceed such limit (according to the order
in which they were granted) shall be treated as Nonstatutory Stock Options, notwithstanding any contrary provision of the applicable Option Agreement(s).

(f) Investment Assurances. The Company may require a Participant, as a condition of exercising or acquiring Common Stock under any Stock Award,
(i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ
a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she
is  capable  of  evaluating,  alone  or  together  with  the  purchaser  representative,  the  merits  and  risks  of  exercising  the  Stock  Award;  and  (ii)  to  give  written
assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Stock Award for the Participant’s own account
and not with any present intention of selling or otherwise distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to
such requirements, shall be inoperative if (A) the issuance of the shares upon the exercise or acquisition of Common Stock under the Stock Award has been
registered under a then currently effective registration statement under the Securities Act, or (B) as to any particular requirement, a determination is made by
counsel  for  the  Company  that  such  requirement  need  not  be  met  in  the  circumstances  under  the  then  applicable  securities  laws.  The  Company  may,  upon
advice  of  counsel  to  the  Company,  place  legends  on  stock  certificates  issued  under  the  Plan  as  such  counsel  deems  necessary  or  appropriate  in  order  to
comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock.

(g)  Withholding  Obligations.  Unless  prohibited  by  the  terms  of  a  Stock  Award  Agreement,  the  Company  may,  in  its  sole  discretion,  satisfy  any
federal,  state  or  local  tax  withholding  obligation  relating  to  an  Award  by  any  of  the  following  means  or  by  a  combination  of  such  means:  (i)  causing  the
Participant  to  tender  a  cash  payment;  (ii)    withholding  shares  of  Common  Stock  from  the  shares  of  Common  Stock  issued  or  otherwise  issuable  to  the
Participant in connection with the Award; provided, however, that no shares of Common Stock are withheld with a value exceeding the minimum amount of
tax required to be withheld by law (or such lesser amount as may be necessary to avoid classification of the Stock Award as a liability for financial accounting
purposes); (iii) withholding cash from an Award settled in cash; (iv) withholding payment from any amounts otherwise payable to the Participant; or (v) by
such other method as may be set forth in the Award Agreement.

9

 
 
 
 
 
 
 
 
 
 
 
 
 
(h) Electronic Delivery. Any reference herein to a “written” agreement or document shall include any agreement or document delivered electronically

or posted on the Company’s intranet (or other shared electronic medium controlled by the Company to which the Participant has access).

(i) Deferrals. To  the  extent  permitted  by  applicable  law,  the  Board,  in  its  sole  discretion,  may  determine  that  the  delivery  of  Common  Stock  or  the
payment of cash, upon the exercise, vesting or settlement of all or a portion of any Award may be deferred and may establish programs and procedures for
deferral  elections  to  be  made  by  Participants.  Deferrals  by  Participants  will  be  made  in  accordance  with  Section  409A  of  the  Code.  Consistent  with
Section 409A of the Code, the Board may provide for distributions while a Participant is still an employee or otherwise providing services to the Company.
The  Board  is  authorized  to  make  deferrals  of Awards  and  determine  when,  and  in  what  annual  percentages,  Participants  may  receive  payments,  including
lump  sum  payments,  following  the  Participant’s  termination  of  Continuous  Service,  and  implement  such  other  terms  and  conditions  consistent  with  the
provisions of the Plan and in accordance with applicable law.

(j) Compliance with Section 409A. To the extent that the Board determines that any Award granted hereunder is subject to Section 409A of the Code,
the Award Agreement evidencing such Award shall incorporate the terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1)
of the Code. To the extent applicable, the Plan and Award Agreements shall be interpreted in accordance with Section 409A of the Code. Notwithstanding
anything to the contrary in this Plan (and unless the Award Agreement specifically provides otherwise), if the shares of Common Stock are publicly traded
and  a  Participant  holding  an  Award  that  constitutes  “deferred  compensation”  under  Section  409A  of  the  Code  is  a  “specified  employee”  for  purposes  of
Section 409A of the Code, no distribution or payment of any amount shall be made upon a “separation from service” before a date that is six (6) months
following  the  date  of  such  Participant’s  “separation  from  service”  (as  defined  in  Section  409A  of  the  Code  without  regard  to  alternative  definitions
thereunder) or, if earlier, the date of the Participant’s death.

9. ADJUSTMENTS UPON CHANGES IN COMMON STOCK; OTHER CORPORATE EVENTS.

(a) Capitalization Adjustments. In the event of a Capitalization Adjustment, the Board shall appropriately and proportionately adjust: (i) the class(es)
and  maximum  number  of  securities  subject  to  the  Plan  pursuant  to  Section  3(a),  (ii)  the  class(es)  and  maximum  number  of  securities  that  may  be  issued
pursuant to the exercise of Incentive Stock Options pursuant to Section 3(c), (iii) the class(es) and maximum number of securities that may be awarded to any
person pursuant to Sections 3(d) and 6(c)(i), and (iv) the class(es) and number of securities and price per share of stock subject to outstanding Stock Awards.
The Board shall make such adjustments, and its determination shall be final, binding and conclusive.

(b)  Dissolution  or  Liquidation.  Except  as  otherwise  provided  in  the  Stock  Award  Agreement,  in  the  event  of  a  dissolution  or  liquidation  of  the
Company, all outstanding Stock Awards (other than Stock Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture
condition  or  the  Company’s  right  of  repurchase)  shall  terminate  immediately  prior  to  the  completion  of  such  dissolution  or  liquidation,  and  the  shares  of
Common  Stock  subject  to  the  Company’s  repurchase  rights  or  subject  to  a  forfeiture  condition  may  be  repurchased  or  reacquired  by  the  Company
notwithstanding the fact that the holder of such Stock Award is providing Continuous Service; provided, however, that the Board may, in its sole discretion,
cause some or all Stock Awards to become fully vested, exercisable and/or no longer subject to repurchase or forfeiture (to the extent such Stock Awards have
not previously expired or terminated) before the dissolution or liquidation is completed but contingent on its completion.

(c) Corporate Transaction. The following provisions shall apply to Stock Awards in the event of a Corporate Transaction unless otherwise provided in
the  instrument  evidencing  the  Stock  Award  or  any  other  written  agreement  between  the  Company  or  any  Affiliate  and  the  Participant  or  unless  otherwise
expressly provided by the Board at the time of grant of a Stock Award.

(i) Stock Awards May Be Assumed, Continued or Substituted. In the event of a Corporate Transaction, any surviving corporation or acquiring
corporation (or the surviving or acquiring corporation’s parent company) may assume or continue any or all Stock Awards outstanding under the Plan or may
substitute similar stock awards for Stock Awards outstanding under the Plan (including but not limited to, awards to acquire the same consideration paid to
the  stockholders  of  the  Company  pursuant  to  the  Corporate  Transaction),  and  any  reacquisition  or  repurchase  rights  held  by  the  Company  in  respect  of
Common Stock issued pursuant to Stock Awards may be assigned by the Company to the successor of the Company (or the successor’s parent company, if
any), in connection with such Corporate Transaction. A surviving corporation or acquiring corporation (or its parent) may choose to assume or continue only
a portion of a Stock Award or substitute a similar stock award for only a portion of a Stock Award, or may choose to assume or continue the Stock Awards
held by some, but not all Participants. The terms of any assumption, continuation or substitution shall be set by the Board.

(ii)  Stock Awards  Not  Assumed,  Continued  or  Substituted.  In  the  event  of  a  Corporate  Transaction  in  which  the  surviving  corporation  or
acquiring  corporation  (or  its  parent  company)  does  not  assume  or  continue  such  outstanding  Stock  Awards  or  substitute  similar  stock  awards  for  such
outstanding Stock Awards, then with respect to Stock Awards that have not been assumed, continued or substituted, the vesting of such Stock Awards (and,
with respect to Options and Stock Appreciation Rights, the time when such Stock Awards may be exercised) shall be accelerated in full to a date prior to the
effective time of such Corporate Transaction (contingent upon the effectiveness of the Corporate Transaction) as the Board shall determine (or, if the Board
shall  not  determine  such  a  date,  to  the  date  that  is  five  (5)  days  prior  to  the  effective  time  of  the  Corporate  Transaction),  and  such  Stock  Awards  shall
terminate if not exercised (if applicable) at or prior to the effective time of the Corporate Transaction, and any reacquisition or repurchase rights held by the
Company with respect to such Stock Awards shall lapse (contingent upon the effectiveness of the Corporate Transaction); provided, however, that the Board
may require Participants to complete and deliver to the Company a notice of exercise before the effective date of a Corporate Transaction, which is contingent
upon the effectiveness of such Corporate Transaction.

(iii)  Payment  for  Stock  Awards  in  Lieu  of  Exercise.  Notwithstanding  the  foregoing,  in  the  event  of  a  Corporate  Transaction  in  which  the
surviving corporation or acquiring corporation (or its parent company) does not assume or continue such outstanding Stock Awards or substitute similar stock
awards for such outstanding Stock Awards and the Stock Award will terminate if not exercised at or prior to the effective time of a Corporate Transaction in
accordance with Section 9(c)(ii), the Board may provide, in its sole discretion, that the holder of such Stock Award may not exercise such Stock Award but
will receive a payment, in such form as may be determined by the Board, equal in value, at the effective time, to the excess, if any, of (A) the value of the
property the Participant would have received upon the exercise of the Stock Award, over (B) any exercise price payable by such holder in connection with
such exercise. For purposes of clarity, this payment may be zero ($0) if the value of the property is equal to or less than the exercise price. Payments under
this  provision  may  be  delayed  to  the  same  extent  that  payment  of  consideration  to  the  holders  of  the  Company’s  Common  Stock  in  connection  with  the
Corporate Transaction is delayed as a result of escrows, earn outs, holdbacks, or any other contingencies.

The Board need not take the same action or actions with respect to all Stock Awards or portions thereof or with respect to all Participants. The Board may
take different actions with respect to the vested and unvested portions of a Stock Award.

(d) Change in Control. In the event of a Change in Control, then, as of the effective time of such Change in Control, the vesting of all outstanding
Stock Awards (and, with respect to Options and Stock Appreciation Rights, the time when such Stock Awards may be exercised) shall be accelerated in full
and any reacquisition or repurchase rights held by the Company with respect to such Stock Awards shall lapse.

10. TERMINATION OR SUSPENSION OF THE PLAN.

(a)  Plan  Term.  The  Board  may  suspend  or  terminate  the  Plan  at  any  time.  Unless  terminated  sooner  by  the  Board,  the  Plan  shall  automatically
terminate on the day before the tenth (10th) anniversary of the Effective Date. No Awards may be granted under the Plan while the Plan is suspended or after
it is terminated.

(b) No Impairment of Rights. Suspension or termination of the Plan shall not impair rights and obligations under any Award granted while the Plan is

in effect except with the written consent of the affected Participant.

12. CHOICE OF LAW.

The law of the State of Delaware shall govern all questions concerning the construction, validity and interpretation of this Plan, without regard to that state’s
conflict of laws rules.

13. DEFINITIONS. As used in the Plan, the following definitions shall apply to the capitalized terms indicated below:

(a) “Affiliate” means, at the time of determination, any “parent” or “subsidiary” of the Company as such terms are defined in Rule 405 promulgated

recapitalization,  reincorporation,  stock  dividend,  dividend  in  property  other  than  cash,  large  nonrecurring  cash  dividend,  stock  split,  liquidating  dividend,
combination of shares, exchange of shares, change in corporate structure or any similar equity restructuring transaction, as that term is used in Statement of
Financial Accounting Standards No. 123 (revised). Notwithstanding the foregoing, the conversion of any convertible securities of the Company shall not be
treated as a Capitalization Adjustment.

(f) “Cause” shall have the meaning ascribed to such term in any written agreement between the Participant and the Company in effect at the time of the
termination  of  the  Participant’s  Continuous  Service  defining  such  term  and,  in  the  absence  of  such  agreement,  such  term  shall  mean,  with  respect  to  a

material  violation  of  any  contract  or  agreement  between  the  Participant  and  the  Company  or  of  any  statutory  duty  owed  to  the  Company;  (iv)  such
Participant’s  unauthorized  use  or  disclosure  of  the  Company’s  confidential  information  or  trade  secrets;  or  (v)  such  Participant’s  gross  misconduct.  The
determination  that  a  termination  of  the  Participant’s  Continuous  Service  is  either  for  Cause  or  without  Cause  shall  be  made  by  the  Company  in  its  sole
discretion.  Any  determination  by  the  Company  that  the  Continuous  Service  of  a  Participant  was  terminated  with  or  without  Cause  for  the  purposes  of
outstanding Awards held by such Participant shall have no effect upon any determination of the rights or obligations of the Company or such Participant for
any other purpose.

(g) “Change in Control” means the occurrence, in a single transaction or in a series of related transactions, of any one or more of the following events:

(i) any Exchange Act Person becomes the Owner, directly or indirectly, of securities of the Company representing more than fifty percent (50%)

Notwithstanding  the  foregoing,  a  Change  in  Control  shall  not  be  deemed  to  occur  (A)  on  account  of  the  acquisition  of  securities  of  the  Company  by  an
investor, any affiliate thereof or any other Exchange Act Person that acquires the Company’s securities in a transaction or series of related transactions the
primary purpose of which is to obtain financing for the Company through the issuance of equity securities (which includes an offering of Common Stock to
the general public through a registration statement filed with the Securities and Exchange Commission), or (B) solely because the level of Ownership held by
any Exchange Act Person (the “Subject Person”) exceeds the designated percentage threshold of the outstanding voting securities as a result of a repurchase
or other acquisition of voting securities by the Company reducing the number of shares outstanding, provided that if a Change in Control would occur (but for
the operation of this subsection (B)) as a result of the acquisition of voting securities by the Company, and after such share acquisition, the Subject Person
becomes the Owner of any additional voting securities that, assuming the repurchase or other acquisition had not occurred, increases the percentage of the
then outstanding voting securities Owned by the Subject Person over the designated percentage threshold, then a Change in Control shall be deemed to occur;

12

 
  
 
  
 
  
 
 
 
 
 
 
 
 
 
 
 
(ii) there is consummated a merger, consolidation or similar transaction involving (directly or indirectly) the Company and, immediately after the
consummation  of  such  merger,  consolidation  or  similar  transaction,  the  stockholders  of  the  Company  immediately  prior  thereto  do  not  Own,  directly  or
indirectly,  either  (A)  outstanding  voting  securities  representing  more  than  fifty  percent  (50%)  of  the  combined  outstanding  voting  power  of  the  surviving
Entity in such merger, consolidation or similar transaction or (B) more than fifty percent (50%) of the combined outstanding voting power of the parent of the
surviving Entity in such merger, consolidation or similar transaction, in each case in substantially the same proportions as their Ownership of the outstanding
voting securities of the Company immediately prior to such transaction;

(iii) there is consummated a sale, lease, exclusive license or other disposition of all or substantially all of the consolidated assets of the Company
and  its  Subsidiaries,  other  than  a  sale,  lease,  license  or  other  disposition  of  all  or  substantially  all  of  the  consolidated  assets  of  the  Company  and  its
Subsidiaries to an Entity, more than fifty percent (50%) of the combined voting power of the voting securities of which are Owned by stockholders of the
Company in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such sale, lease,
license or other disposition; or

constitute at least a majority of the members of the Board; provided, however, that if the appointment or election (or nomination for election) of any new

purposes of this Plan, be considered as a member of the Incumbent Board.

However, service solely as a Director, or payment of a fee for such service, shall not cause a Director to be considered a “Consultant” for purposes of the
Plan. Notwithstanding the foregoing, a person is treated as a Consultant under this Plan only if a Form S-8 Registration Statement under the Securities Act is
available to register either the offer or the sale of the Company’s securities to such person.

(m) “Continuous Service” means that the Participant’s service with the Company or an Affiliate, whether as an Employee, Director or Consultant, is

service with the Company or an Affiliate, shall not terminate a Participant’s Continuous Service; provided, however, if the Entity for which a Participant is
rendering  services  ceases  to  qualify  as  an  Affiliate,  as  determined  by  the  Board,  in  its  sole  discretion,  such  Participant’s  Continuous  Service  shall  be
considered to have terminated on the date such Entity ceases to qualify as an Affiliate. To the extent permitted by law, the Board or the chief executive officer
of  the  Company,  in  that  party’s  sole  discretion,  may  determine  whether  Continuous  Service  shall  be  considered  interrupted  in  the  case  of  (i)  any  leave  of
absence  approved  by  the  Board  or  chief  executive  officer,  including  sick  leave,  military  leave  or  any  other  personal  leave,  or  (ii)  transfers  between  the
Company, an Affiliate, or their successors. Notwithstanding the foregoing, a leave of absence shall be treated as Continuous Service for purposes of vesting in
a Stock Award only to such extent as may be provided in the Company’s leave of absence policy, in the written terms of any leave of absence agreement or
policy applicable to the Participant, or as otherwise required by law.
