2014 Developments

Acquisition

On January 23, 2014, the Company consummated an acquisition pursuant to a written plan of reorganization, in which we merged
with Xenetic Biosciences (UK) Limited (formerly Xenetic Biosciences plc) (“Xenetic UK”), a company incorporated in England and Wales
under the Companies Act of 1985, such that Xenetic UK became a wholly owned subsidiary of the Company (the “Acquisition”). Upon
completion  of  the Acquisition,  we  acquired  all  issued  and  outstanding  shares  of  capital  stock  of  Xenetic  UK. As  a  result,  132,545,504
shares  of  our  common  stock  were  newly  issued  and,  immediately  following  the Acquisition,  there  were  136,045,504  shares  of  common
stock issued and outstanding. At that time, because former Xenetic UK shareholders owned approximately 97% of the combined company
on  a  fully  diluted  basis  and  all  members  of  the  combined  company’s  executive  management  were  from  Xenetic  UK,  Xenetic  UK  was
deemed to be the acquiring company for accounting purposes and the transaction was accounted for as a reverse acquisition in accordance
with accounting principles generally accepted in the United States (“US GAAP”).

Prior to the Acquisition, the Company changed its name from General Sales and Leasing, Inc. to Xenetic Biosciences, Inc. As used in
these consolidated financial statements, unless otherwise indicated, all references herein to “Xenetic”, the “Company”, “we” or “us” refer
to Xenetic Biosciences, Inc. and its wholly owned subsidiaries.

Stock Purchase Agreement

On January 29, 2014 the Company entered into a stock purchase agreement (the “Purchase Agreement”) with Baxter Healthcare SA
(“Baxter SA”), pursuant to which the Company sold to Baxter SA 10,695,187 shares of the Company’s common stock, par value $0.01 per
share, (the “Shares”) for $10 million (the “Purchase Price”)  at  a  price  of  $0.935  per  share  yielding  a  market  cap  of  approximately  $140
million.

The Shares were sold in a private placement and were not registered under the Securities Act, or the securities laws of any state, and
were offered and sold in reliance on the exemption from registration afforded by Section 4(a)(2) and Regulation D (Rule 506) under the
Securities Act  and  corresponding  provisions  of  state  securities  laws,  which  exempt  transactions  by  an  issuer  not  involving  any  public
offering. Baxter SA is an “Accredited Investor” as such term is defined in Regulation D promulgated under the Securities Act. For a further
discussion of the Purchase Agreement please refer to “Market for Registrant’s Common Equity,  Related  Stockholder  Matters  and  Issuer
Purchases of Equity Securities – Recent Sales of Unregistered Securities” in this Annual Report filed on Form 10-K.

Overview of Business

The Company, carrying on business in a single operating segment, is a clinical stage biopharmaceutical company that is focused on
the research and development of certain pharmaceutical products for use in humans that incorporate the use of its patented and proprietary
platform technologies that we believe will enable the creation of novel and next generation drug therapies primarily for orphan indications.

We  hold  over  147  US  and  international  patents  issued,  more  than  90  patents  pending  and  other  proprietary  rights  to  three  distinct

platform technologies that are designed to treat a variety of indications with potential use advantages over competing products.

The Company’s three distinct technologies are summarized below:

PolyXen®

OncoHist™

ImuXen®

An enabling technology that utilizes Polysialic Acid (“PSA”), a biopolymer, consisting of a chain of sialic acids which is a
natural constituent of the human body. PSA is designed to extend the half-life in circulation in the human body for a variety
of existing drug molecules and, thereby, to create potentially superior next generation drug candidates.
A novel therapeutic platform that utilizes the properties of the human histone H1.3 (“H1.3”) for the development of drug
candidates  for  the  treatment  of  a  broad  range  of  cancer  indications.  OncoHist™,  unlike  many  competing  oncology
therapies, is based on a molecule occurring naturally in the human body, in the cell nucleus, and is therefore expected to be
less toxic and immunogenetic than other oncology therapies.
A  novel  liposomal  co-entrapment  encapsulation  technology  designed  to  create  new  vaccines  and  improve  the  use  and
efficacy  of  certain  existing  vaccines  for  use  in  the  human  body.  The  technology  is  based  on  the  co-entrapment  of  the
nominated antigen(s) in a liposomal vesicle, a design that is intended to maximize both cell and immune system mediated
responses.

All of the Company’s drug candidates are in the development stage and none has yet received regulatory approval for marketing in

the U.S. by the U.S. Food and Drug Administration (the “FDA”) or by any applicable agencies in other countries.

First  formed  in  1997  as  a  spin  out  from  University  College  London  School  of  Pharmacy,  our  laboratories  were  based  in  London,
England, until the end of 2013. In January 2014, the Company completed the relocation of its research base from England to the U.S. The
Company made its first move towards the U.S. when, in early 2013, it committed to set up a Drug Development Centre of Excellence in the
Boston area, a decision that resulted in the physical relocation of its scientific level of effort to its newly opened laboratory in Lexington,
Massachusetts. The next pivotal stage of corporate strategy was also concluded in January 2014 when the Company completed a listing in
the US on the OTC markets that resulted in its present operations as a clinical stage biopharmaceutical business. The Company believes
that it will be better able to attract and retain qualified scientific researchers and other staff in its new Lexington location due to the Boston
area having a wealth of talent in orphan drug development and market launch expertise.

Our Business Strategy

The Company intends to advance the clinical development of its drug candidates through a combination of conducting its own in-
house  research  and  through  the  use  of  the  outside  services  of  contract  manufacturing  and  research  organizations.  The  OncoHist™  drug
candidate  for AML  has  been  granted  orphan  drug  designation  by  the  FDA  and  European  Medicines Agency  (“EMA”).  The  Company
expects to seek further orphan drug designations relating to this novel potential cancer therapeutic over the next twelve months, working in
concert  with  the  Dana  Farber  Cancer  Institute.  The  advancement  of  its  drug  candidates  is  dependent,  in  part,  on  several  important  co-
development  collaborations  and  strategic  arrangements.  Together  with  its  collaborative  partners,  Baxter  Healthcare  SA  and  Baxter
Healthcare  Corporation  (together  referred  to  as  “Baxter”),  a  shareholder  in  the  Company,  SynBio  LLC  (“SynBio”),  a  Russian
pharmaceutical  company  and  significant  shareholder  in  the  Company,  OJSC  (“Open  Joint  Stock  Company”)  Pharmsynthez
(“Pharmsynthez”),  a  Russian  pharmaceutical  company  and  related  party  to  SynBio  and  Serum  Institute  of  India  Limited  (“Serum
Institute”), one of India’s largest biotech companies and a shareholder in the Company, the Company is focused on developing its pipeline
of  next  generation  bio-therapeutics  and  novel  orphan  drugs  in  oncology  based  on  the  Company’s  PolyXen®,  OncoHist™  and  ImuXen®
technology platforms.

As  part  of  the  Company’s  strategy,  it  out-licensed  the  rights  to  twelve  drug  candidates  for  research,  development  and
commercialization within certain defined territories including the Russian Federation and Commonwealth of Independent States (“CIS”),
with  respect  to  SynBio  and  Pharmsynthez,  and  India,  with  respect  to  Serum  Institute.  SynBio,  Pharmsynthez  and  Serum  Institute  are
responsible for funding the research, development and commercialization of each drug candidate in those territories at their own expense.
The out-license agreements contain provisions that allow the Company access to all underlying research materials and to receive royalties
related to any of these drug candidates that may be approved and marketed in those territories. The Company utilizes its access to that data
to determine which of those twelve drug candidates it believes are worthwhile to pursue for research, development and commercialization
in the US and elsewhere.

The  Company’s  strategy  is  to  develop  its  orphan  drug  candidates  through  to  regulatory  approval.  The  Company  then  plans  to
commercialize those orphan drug candidates. Non-orphan drug candidates vested in its pipeline via its collaborations include ErepoXen®;
polysialylated oxyntomodulin, for diabetes and obesity; and a Multiple Sclerosis vaccine candidate, MyeloXen™. The Company intends to
develop these candidates to a stage that will enable it to seek profitable out-licensing arrangements with major pharmaceutical companies
for  further  development  and  eventual  commercialization,  in  exchange  for  milestone  payments  and  royalties  from  product  sales.  Its
collaborative out-licensing agreements relating to the platforms are an integral part of its early-stage strategy.

Even with regard to its strategy of current and planned future co-development collaborations and out-licensing, the Company must
raise  additional  capital  in  order  to  develop  its  drug  candidates  to  the  point  of  commercialization.  The  Company’s  management  will
regularly  make  evaluations  in  concert  with  the  Company’s  Board  of  Directors  as  to  when  to  seek  additional  capital  through  various
financing structures for the purpose of pursuing its business strategy. Although the Company is optimistic, there can be no assurance that it
will be successful in raising additional working capital in the future. If not successful, the Company’s business could be adversely affected.

Reliance on Principal Customer

Since August 2005, Baxter has been a principal customer of the Company, accounting for the substantial portion of the Company’s
revenue,  through  up-front  payments  and  fee  for  services.  Please  refer  to  the  agreement  with  Baxter  under  the  caption  “Significant  Co-
Development  Collaborations  and  Strategic  Arrangements”  below  for  further  information  regarding  the  importance  of  the  Company’s
relationship with Baxter.

Our Technologies

PolyXen®

PolyXen® is a platform technology based on the concept of polysialylation. PSA is a polymer chain composed of sialic acids linked
together.  Sialic  acid  is  found  on  the  external  membrane  of  a  number  of  cell  types  in  the  body.  In  addition,  it  is  a  natural  component
expressed on the external membrane on a number of bacterial types. The chain of sialic acid molecules can be anywhere from 4 to over 200
individual  sialic  acid  molecules  in  length.  The  Company  uses  the  linear  form  of  PSA  called  colominic  acid.  It  is  a  natural,  hydrophilic
polymer isolated from a bacterial strain of E. coli K1. This natural glycan is negatively charged, non-toxic and is biodegradable. The PSA
chain  is  extensively  purified  from  large-scale  bacterial  cultures  under  Current  Good  Manufacturing  Practices  conditions,  modified  to
specified  sizes  and  then  attached  to  defined  sites  on  the  therapeutic.  Both  the  site  of  attachment  and  the  length  of  the  PSA  chain  can
enhance the properties of the therapeutic.

The  major  effect  of  PSA  addition  to  a  therapeutic  is  to  change  the  apparent  hydrodynamic  radius  of  the  molecule.  This  physical
alteration then changes a number of the biological characteristics of the therapeutic. The most noticeable, and perhaps the most relevant, is
an  extension  of  the  lifetime  of  the  therapeutic  in  blood  circulation.  This  is  due  to  the  increase  in  the  size  of  the  drug  which  results  in  a
decrease  in  the  clearance  rate  of  the  molecule  in  the  kidney  by  glomerular  filtration.  In  addition,  studies  have  shown  changes  in  other
biological characteristics such as protease sensitivity and temperature sensitivity. An added benefit is that the conjugated molecules are less
viscous  in  solution  than  comparable  other  technologies,  providing  the  potential  for  easier  injections  and  fewer  injection  site  reactions.
Furthermore,  we  believe  that  adding  PSA  to  an  existing  marketed  drug  may  allow  for  patent  extension,  thereby  potentially  creating  a
patent-protected next generation candidate.

The current standard for certain biologic delivery agents is Polyethylene Glycol (“PEG”) which is attached similarly to therapeutics.
The mode of action between PSA and PEG is similar, increasing the apparent size of the molecule and thereby increasing the circulating
time  of  the  drug  in  the  blood.  PEGylation  is  a  proven  technology  that  can  offer  advantages  in  terms  of  pharmacokinetics  and
pharmacodynamics for therapeutics over non-modified, first generation molecules. There are a number of PEG-modified molecules on the
market, in clinical trials and under development. However, PEGylation is considered to have limitations, such as non-biodegradability and,
at high doses, may thereby result in intra-cellular accumulation, potentially leading to vacuole formation in the cells. In contrast, because
PSA  is  a  chain  of  sialic  acids,  which  are  natural  constituents  of  the  human  body,  it  is  biodegradable  into  individual  sialic  acid  units.  In
addition, PEG in many cases has been shown to be immunogenic when coupled to proteins and can activate the complement system. PEG
has also demonstrated limitations on a few select molecules. PSA has to date been shown to be non-immunogenic. We believe PSA may
provide the advantages of PEG without many of its disadvantages, offering a potential advance over PEG molecules.

OncoHist™

OncoHist™ is based on research covered under our patent portfolio related to novel functions of histones. Histone H1 has strong anti-
proliferative  properties  against  cancer  cells  of  different  histological  origin.  This  has  been  demonstrated  extensively  for  hematologic
malignancies, such as leukemias, lymphomas, and myelomas, and also for tumors from other tissues. Susceptibility of cells to the cytotoxic
effect of histones is determined by the ability of histone H1 to selectively destabilize the tumor cell membrane, which results in cell death.

A novel form of the molecule was developed by the Company and a patent filed for the protection of the new chemical entity, N-bis-
met-histone 1.3 (OncoHist™) in use against cancer, providing patent protection at least until 2027. The activity of the new molecule was
tested on 58 tumor cell lines derived from various tissues. Hematopoietic tumor cell lines were found to be among the most sensitive cell
lines.  The  mechanism  of  action  appears  to  be  novel,  involving  the  binding  of  OncoHist™  to  the  cell  membrane,  which  is  completely
different  than  that  of  other  therapeutic  agents  on  the  market  for  hematopoietic  cancers.  Confirmatory  work  on  this  mode  of  action  with
more detailed analyses is being completed by Dana-Farber Cancer Institute (“Dana-Farber”). Hematopoietic tumor lines resistant to current
chemotherapeutic agents have shown sensitivity to OncoHist™.

OncoHist™’s  potency  and  potential  to  inhibit  growth  of  cells  from  various  histological  origins  were  confirmed  through  in-vitro
testing  against  the  US  National  Cancer  Institute  60  (“NCI-60”).  OncoHist™  was  awarded  orphan  drug  designation  (Orphan  Medicinal
Product Designation (“OMPD”)) for treatment of AML by the European Commission in December 2007 and by the FDA in October 2008.
OncoHist™ was awarded an additional OMPD status for Acute Lymphocytic Leukemia (“ALL”) by the EMA.

A Phase I-II trial to evaluate the safety and tolerability of OncoHist™ was conducted in 2008 at Saarland University, in Germany
with  22 AML  patients.  Tolerability  and  safety  results  were  favorable  with  indications  of  the  drug  being  immunologically  safe.  Clinical
effects were noted in seven patients with three partial remissions. Most notably, two patients who had received two treatment cycles each
experienced stabilization of their disease for 7 and 17 months.

A clinical safety trial with a planned 120 AML  patients  was  in  progress  and  being  performed  by  SynBio  in  clinical  centers  in  the
Russian  Federation.  The  aim  of  this  trial  was  to  examine  the  potential  benefits  of  OncoHist™  in  combination  with  standard  HAM
chemotherapy: high dose cytarabine with mitoxantrone. During execution of the SynBio AML trial the Russian Ministry of Health issued
changes  in  their  standard  of  care  for  treating AML  patients.  High  dose  cytarabine  chemotherapy  was  determined  to  offer  no  benefits  in
terms of efficacy as compared to lower dose therapy and was discontinued. The study was stopped and the study report is now in progress.

Based upon our analysis of data from the preliminary AML trial performed by SynBio in the Russian Federation, and data developed
in Germany at Saarland University, the Company has undertaken pre-clinical development and IND-enabling animal studies in the US in
support of a planned phase I/II(a) IND filing with the FDA in the first half of 2016. Xenetic has had a pre-IND meeting with the FDA to
discuss  the  OncoHist AML  program.  The  FDA  comments  will  be  addressed  by  time  of  IND  submission. A  Phase  I/II  Non-Hodgkin’s
Lymphoma (“NHL”) safety trial has been completed in Russia. As an integral part of the Company’s strategy, we intend to await later stage
clinical data on NHL to determine whether to progress this candidate into US FDA trials.

Other Technologies

ImuXen®

ImuXen®  is  a  patented  platform  technology  based  on  the  concept  of  simultaneous  delivery  of  multiple  Active  Pharmaceutical
Ingredients (“APIs”) as antigens within the same liposome. The liposomes are composed of lipids that encapsulate an aqueous core. The
APIs  can  be  trapped  in  the  core,  be  associated  with  the  lipids,  or  both.  Proteins,  peptides,  nucleic  acids,  polysaccharides  and  live  or
inactivated infectious agents can all be used as an API with the same liposome. Both the size and the lipid composition can be controlled
which  affects  the  biological  properties  of  the  liposome.  Manufacturing  involves  the  passive  entrapment  of  the  vaccine APIs  by  freeze
drying commercially available liposomes with the antigens of interest.

Having  multiple  APIs  formulated  with  the  same  liposome  allows  simultaneous  delivery  of  the  antigens  to  the  same  antigen-
presenting  cell.  This  may  allow  a  more  efficient  immune  response  to  all  the  agents  presented.  In  addition,  it  is  possible  that  multiple
vaccines can be delivered with a single injection. Relevant pre-clinical studies have indicated a reduction in the dose required, a reduction in
the number of doses required and a faster immune response time. This efficient immune response also may allow for use of antigens that
traditionally give a poor antibody response.

This  technology  is  not  currently  the  focus  of  clinical  development  for  the  Company.  However  through  a  license  agreement  with

Pharmsynthez, there is a novel Multiple Sclerosis vaccine that is in clinical development in Russia.

A Phase I/II clinical trial to treat Relapsing Remitting Multiple Sclerosis and Secondary Progressive Multiple Sclerosis is in progress
by  Synbio  in  the  Russian  Federation.  Peptides  corresponding  to  antigenic  sections  of  basic  myelin  protein  were  encapsulated  within
liposomes  to  be  used  as  the  therapeutic  agent  (MyeloXen™). Administration  of  MyeloXen™  to  patients  has  occurred  and  follow-up
monitoring is in progress. As an integral part of the Company’s strategy, we await later stage clinical data on MyeloXen™ to determine
whether to progress this candidate into FDA trials and eventual out-licensing.

Significant Co-Development Collaborations and Strategic Arrangements:

Baxter Healthcare SA and Baxter Healthcare Corporation

In August 2005, the Company entered into an exclusive research, development, license and supply agreement with Baxter Healthcare
SA (“Baxter SA”) and Baxter Healthcare Corporation (together referred to as “Baxter”) to develop products with an extended half-life of
certain proteins and molecules using the Company’s patent protected PolyXen ® technology whereby polysialic acid (“PSA” – a chain of
polysialic acids) is conjugated with Baxter’s proprietary molecule(s) designed to create a longer-acting haemophilia drug, a polysialylated
recombinant Factor VIII (“rFVIII”) protein than what is currently available on the market. Baxter also has rights that extend to treatments
of the failure of blood to coagulate. Baxter expects to commence human clinical trials on this novel drug candidate during the first half of
2016.

This agreement has been amended several times since 2005, most recently in January 2014. The January 2014 amendment provides
for  increased  future  development,  regulatory,  sales  and  deadline  extension  receipts,  restructured  target  deadlines  and  royalty  receipts  on
potential  net  sales.  The  Company  is  entitled  to  up  to  $100  million  in  potential  development,  regulatory,  sales  and  deadline  extension
receipts,  which  are  contingent  on  the  performance  of  Baxter  achieving  certain  milestones.  The  Company  is  also  entitled  to  royalties  on
potential net sales. In connection with this amendment, Baxter SA also made a $10 million equity investment at a price of $0.935 per share,
which is a post money market cap of approximately $140 million in the Company in exchange for 10,695,187 shares of the Company’s
common stock during January 2014.

Through December 31, 2014, the Company and Baxter continued to engage in research and development activities. No amounts were
recognized as revenue during the year ended December 31, 2014. $1 million was received and recognized as revenue during the year ended
December  31,  2013  related  to  this  collaboration  as  the  Company’s  continued  performance  or  future  obligations  were  considered
inconsequential  or  perfunctory.  Since  August  2005,  the  Company  has  received  approximately  $19  million  from  Baxter  that  includes
milestone receipts, fees for services and a $10 million purchase of common stock of the Company in January 2014. The Company received
a non-refundable $2 million payment from Baxter in 2010 and granted Baxter warrants to purchase approximately 4.6 million new shares of
common stock of the Company in connection with the 2010 amendment to the Baxter Agreement.

Baxter is in the pre-clinical phase of its development effort in connection with this collaboration. Baxter has agreed to meet a number
of clinical milestones with strict timelines under the 2014 amendment relating to: Clinical Trial Authorization  submission, Final Clinical
Study Report and  Biologics  License Application  (“BLA”)  submission.  There  are  very  limited  provisions  to  further  modify  the  Baxter
Agreement. There can be no assurance if or when Baxter will actually achieve any of the due diligence milestones.

Baxter  is  a  related  party  of  the  Company,  with  a  share  ownership  of  approximately  8.7%  of  the  total  issued  common  stock  as  of

December 31, 2014.

SynBio LLC

In August  2011  the  Company  entered  into  a  stock  subscription  and  collaborative  development  agreement  with  SynBio  (the  “Co-
Development Agreement”)  pursuant  to  which  the  Company  granted  SynBio  an  exclusive  license  to  develop,  market  and  commercialize
certain drug candidates utilizing molecules based on the Company’s PolyXen® and OncoHist™ technologies in the Russian market and the
Commonwealth  of  Independent  States  (the  “CIS”)  (including  Armenia,  Azerbaijan,  Belarus,  Kazakhstan,  Kyrgyzstan,  Republic  of
Moldova, Tajikistan, Turkmenistan and Uzbekistan), collectively the “SynBio Market”. In exchange for the Company granting to SynBio
those certain license rights, SynBio granted an exclusive license to the Company to use any SynBio pre-clinical and clinical data generated
by SynBio, at its own expense, in connection with those development efforts and to engage in the development and commercialization of
drug  candidates  that  may  arise  from  the  collaboration  in  any  territory  outside  of  Russia  and  the  CIS  based  upon  the  Co-Development
Agreement.

The Company hopes and expects to mitigate certain risks of drug development by reviewing human clinical data arising out of this
collaboration  with  SynBio  before  the  Company  considers  taking  the  particular  drug  candidate  into  FDA  and  EMA  trials.  Under  the  Co-
Development Agreement,  SynBio  is  responsible  for  progressing  six  new  product  candidates  through  human  proof  of  concept  trials  in
Russia  as  primary  validation  for  the  initiation  of  EMA/FDA  clinical  trials  by  the  Company.  The  primary  goal  of  the  Co-Development
Agreement  is  to  research  and  develop  drug  candidates  for  planned  commercialization  using  SynBio  and  the  Company’s  combined
respective expertise and technologies. Drug candidates must meet the success criteria as decided upon by a joint steering committee, which
includes representation from both SynBio and the Company, where the Company has the right to appoint the Chair who has the casting
vote. Once a potential drug candidate is selected, clinical trials will be separately conducted by each company in their respective territories
with the goal to achieve regulatory approval of the products for commercial sale.

SynBio is wholly are responsible for funding and conducting their own research and clinical development activities in Russia as the
Company is wholly responsible for funding and conducting their own research and clinical development activities in the US, Europe and
elsewhere  ex-Russia  and  the  ex-CIS  regions.  There  are  no  milestones  or  other  research  related  payments  provided  for  under  the  Co-
Development Agreement  other  than  fees  for  the  provision  of  each  party’s  respective  research  supplies  based  on  their  technology  and
royalties payable to the Company based on SynBio sales. For the years ended December 31, 2014 and 2013, the Company has recognized
no supply service revenues in connection with the Co-Development Agreement.

Concurrent  with  entering  into  the  Co-Development  Agreement,  the  Company  entered  into  a  stock  subscription  agreement  with
SynBio  pursuant  to  which  the  Company  sold  SynBio  approximately  35.5  million  shares  of  newly  issued  common  stock  for  cash  of
approximately $18.6 million.

In  furtherance  of  our  co-development  clinical  objectives,  on  December  31,  2014  the  Company  granted  to  SynBio  certain  warrants
that  contain  vesting  triggers  based  on  the  achievement  by  SynBio  of  certain  clinical  development  objectives  within  specific  timeframes.
This grant consisted of a warrant to purchase 6,745,000 new shares of common stock at an exercise price of $0.77 per share (“SynBio 2014
Warrant”). Simultaneously with the SynBio 2014 Warrant grant, the Company granted additional warrants to purchase 320,000 aggregate
new shares of common stock to SynBio and Pharmsynthez non-director designees under the same terms and conditions of the SynBio 2014
Warrant. Pharmsynthez is a related party of SynBio and a collaboration partner of the Company. As part of this transaction, the warrant
granted to SynBio in 2011 was canceled and of no further force and effect. The SynBio 2014 Warrant expires on December 30, 2019 and
no warrants were exercised during the year ended December 31, 2014.

Pursuant  to  the  Relationship  Deed  signed  concurrent  with  the  2011  Co-Development Agreement  and  subscription,  the  Company
granted SynBio (as Controlling Shareholder) the right to appoint two directors to the extent their shareholding is greater than 40% in the
Company.  The  Relationship  Deed  of  2011  was  replaced  in  January  2014  with  a  Director Appointment Agreement  containing  that  same
provision. Further undertakings therein state that, as long as the Controlling Shareholder holds more than 25% of the Company’s common
stock, all transactions and relationships between it and the Company will, (a) be at arm’s length and on a normal commercial basis; (b) it
will not seek to exercise any day-to-day operational or managerial control over the business of the Company, nor, (c) influence any director
or  non-executive  director  in  any  way  in  regard  to  the  conduct  of  the  Company’s  business.  The  agreement  contains  further  provisions
relating, inter alia, to: nominee board appointments, conflicts of interest, acting in good faith and terms of confidentiality. SynBio is an
affiliate of the Company, with a share ownership of approximately 41.6% of the total issued common stock as of December 31, 2014.

Serum Institute of India Limited

In the period from 2004 through 2011, the Company entered into and amended certain license and supply agreements with Serum
Institute. The original license agreement with Serum Institute was a collaborative Development and Manufacturing Arrangement (“DMA”)
to  develop  agreed  upon  potential  commercial  product  candidates  using  the  Company’s  PolyXen ®  technology.  Serum  Institute  then
endeavored  to  further  develop  the  potential  commercial  product  candidates  and  eventually  initiate  pre-clinical  and  clinical  trials  at  their
own  cost.  The  agreement  was  amended  in  2011,  resulting  in  the  surrender  of  development  rights  for  14  potential  commercial  product
candidates in 2012, which were vested to Serum Institute under the terms of the previous agreements, back to the Company.

Following the 2011 amendment, Serum Institute retained an exclusive license to use the Company’s PolyXen® technology to research
and  develop  one  potential  commercial  product,  Polysialylated  Erythropoietin  (“PSA-EPO”).  Serum  Institute  will  be  responsible  for
conducting  all  pre-clinical  and  clinical  trials  required  to  achieve  regulatory  approvals  within  territories  outside  of  certain  predetermined
territories  assigned  to  the  Company,  which  include  the  US,  the  European  Economic Area,  and  Japan,  among  other  territories,  at  Serum
Institute’s own expense. The royalty payment schedule based on net revenues on the future commercial sales of PSA-EPO under the DMA
was also modified as a result of the 2011 amendment. Royalty payments are payable by Serum Institute to the Company for net sales to
certain  customers  in  the  Serum  Institute  sales  territory.  Royalty  payments  are  payable  by  the  Company  to  Serum  Institute  for  net  sales
received  by  the  Company  over  the  term  of  the  license.  No  royalty  revenue  or  expense  was  recognized  by  the  Company  related  to  the
Serum  Institute  arrangement  during  the  years  ended  December  31,  2014  and  2013.  There  are  no  milestone  or  other  research-related
payments  due  under  the  DMA.  Through  December  31,  2014,  the  Company  and  Serum  Institute  continued  to  engage  in  research  and
development activities with no resultant commercial products.

10

 
 
 
 
 
 
 
 
 
In  furtherance  of  our  co-development  clinical  objectives,  on  December  31,  2014  the  Company  granted  to  Serum  Institute  certain
warrants  that  contain  vesting  triggers  based  on  the  achievement  by  Serum  Institute  of  certain  clinical  development  objectives  within
specific timeframes. This grant consisted of a warrant to purchase 3,200,000 new shares of common stock at an exercise price of $0.77 per
share (“Serum 2014 Warrant”). Simultaneously with the Serum 2014 Warrant grant, the Company granted additional warrants to purchase
160,000  aggregate  new  shares  of  common  stock  to  Serum  Institute  non-director  designees  under  the  same  terms  and  conditions  of  the
Serum  2014  Warrant.  The  Serum  2014  Warrant  expires  on  December  30,  2019  and  no  warrants  were  exercised  during  the  year  ended
December 31, 2014.

In addition, the DMA allows for Serum Institute to nominate a non-executive director to the Board of Directors of the Company as

long as Serum Institute or its subsidiaries holds at least 6% of the Company’s common stock. Serum Institute is a related party of the
Company, with a share ownership of approximately 9.2% of the total issued common stock as of December 31, 2014.

OJSC Pharmsynthez

In November 2011, the Company entered into a collaborative research and development license agreement with OJSC Pharmsynthez
(the  “Pharmsynthez  Arrangement”)  pursuant  to  which  the  Company  granted  an  exclusive  license  to  Pharmsynthez  to  develop,
commercialize and market six product candidates based on the Company’s PolyXen® and ImuXen® technology anywhere within Russia
and the CIS. In exchange, Pharmsynthez granted an exclusive license to the Company to use any pre-clinical and clinical data developed by
Pharmsynthez, within the scope of the Pharmsynthez Arrangement, and to engage in further research, development and commercialization
of drug candidates in any territory outside of Russia and the CIS at the Company’s own expense.

In accordance with the terms of the Pharmsynthez Arrangement, the Company licensed certain PolyXen® and ImuXen® technology
rights for use in Russia and the CIS as well as certain clinical and research data developed by the Company on the six product candidates to
Pharmsynthez.

The Company hopes and expects to mitigate certain risks of drug development by reviewing human clinical data arising out of this
collaboration with Pharmsynthez before the Company takes the particular drug candidate into FDA and EMA trials, a strategy designed to
mitigate  drug  development  risks.  Under  the  agreement,  Pharmsynthez  is  responsible  for  progressing  six  new  drug  candidates  through
human proof of concept trials in Russia as primary validation prior to the initiation of EMA/FDA clinical trials by the Company outside of
Russia. The license agreement will operate alongside the current arrangements which the Company has entered into with SynBio, discussed
above.

A  joint  steering  committee  where  the  Company  has  the  right  to  appoint  the  Chair  who  has  the  casting  vote  was  established  to
facilitate  the  communication  of  scientific  data  and  to  assist  generally  with  each  party’s  research  decisions  and  to  monitor  research  and
development progress under the Pharmsynthez Arrangement.

Pharmsynthez is wholly responsible for funding and conducting their own research and clinical development activities in Russia. The
Company is wholly responsible for funding and conducting its own research and clinical development activities in the US, Europe and the
rest of the world outside of Russia and the ex-CIS regions. There are no milestones or other research related payments provided for under
the Co-Development Agreement other than royalties.

Pharmsynthez is a related party of SynBio, which is an affiliate of the Company. In addition, one of the Company’s directors is also a

director of SynBio and Pharmsynthez.

Most advanced product candidate in the Company pipeline: ErepoXen®

The  Company’s  drug  candidate  that  is  currently  the  most  advanced  in  its  clinical  pipeline  is  ErepoXen®  (polysialylated
erythropoietin  (“PSA-EPO”))  which  uses  the  Company’s  PolyXen®  technology  for  the  treatment  of  anemia  in  Chronic  Kidney  Disease
(“CKD”)  patients.  ErepoXen®  is  in  a  Company-sponsored  Phase  II  escalating  repeat  subcutaneous  dose-ranging  study  in Australia  and
New Zealand for pre-dialysis CKD patients. This trial is designed to be compliant with the International Conference on Harmonization of
Technical Requirements for Registration of Pharmaceuticals for Human Use (“ICH”). ErepoXen® has also been a co-development project
with  our  long-established  strategic  partner,  Serum  Institute,  and  is  in  Phase  II(a)  clinical  trials  in  India  for  intravenous  administration  to
patients on dialysis. In addition, ErepoXen® is also in a 150 patient Phase II(b)/III clinical trial in Russia to directly compare ErepoXen® to
Aranesp.  The  Company  expects  SynBio  to  enter  the  commercialization  and  marketing  stage  of  ErepoXen®  in  the  Russian  and  CIS
markets, as the first market launch for a PSA candidate.

The  Company’s  commercialization  strategy  for  ErepoXen®,  being  a  potentially  mainstream  drug  addressing  a  substantial  global
market,  includes  seeking  an  out-license  arrangement  for  the  continuing  development  of  ErepoXen®  as  either  a  Phase  II(b)  or  Phase  III
candidate  with  a  well-capitalized  license  partner  more  experienced  at  taking  drug  candidates  through  the  latter  stages  of  human  clinical
trials and better able to execute a global market launch. If successful, this strategy could:

(a)

(b)

be the beginning of the monetization of the Company’s IP investment to date in ErepoXen® by way of an upfront license payment plus
milestone payments as the product is advanced through the clinic; and
potentially reduce the timeline for incoming royalty revenues if ErepoXen® is taken to market by an already leading provider with an
established market presence.

The  ErepoXen®  strategy,  when  implemented,  should  have  the  effect  of  decreasing  demands  on  the  Company’s  own  financial  and
working capital resources, allowing those resources to be applied towards the in-house development and marketing of new orphan and rare
disease  candidates  where  the  Company  is  better  able  to  maintain  financial  and  clinical  control  throughout  the  process  from  pre-clinical
development, through IND filing, human clinical trials, and potentially market approval and product launch.

In addition, ErepoXen® has also received regulatory approval to enter Phase II(b)/III human clinical trials in Russia. The Company
expects  SynBio  (one  of  its  Russian  co-development  partners)  to  enter  the  commercialization  and  marketing  stage  of  ErepoXen®  in  the
Russian and CIS markets as the first market launch for a PSA candidate.

Second most advanced product candidate in the Company pipeline: OncoHist™

The Company’s second most advanced drug candidate is OncoHist™ AML. Continuing development of OncoHist™ is the top 2015
priority for the Company in the US. The Company, utilizing clinical material supplied by SynBio, commenced pre-clinical toxicity studies
during 2014 that are expected to be completed in the first half of 2015. In addition, the Company is in the process of establishing a second
source supplier of OncoHist™ cGMP material suitable for humans in Phase I/II(a) clinical trials. We intend to commence clinical trials in
the  US  upon  completion  of  IND  enabling  studies,  establishment  of  a  source  of  cGMP  material  suitable  for  those  trials  and  upon  raising
additional working capital to support those trials. Based on current estimates, we do not expect to commence clinical trials before the end of
2015.  Certain  OncoHist™  data,  generated  by  SynBio,  that  is  available  to  us  for  analysis  has  advanced  our  understanding  of  this  drug
candidate at a reduced cost to the Company when compared to the cost of the Company generating the same data using its own capital.

13

 
 
 
 
 
 
 
 
 
 
Other product candidates in the Company pipeline

The Company believes certain additional orphan and non-orphan oncology drug candidates may be developed utilizing certain of our
existing and future pre-clinical and clinical data. Specifically, we expect to be able to utilize the results from substantially all of our pre-
clinical  toxicity  and  certain  other  pre-clinical  data  generated  in  the  development  of  OncoHist™ AML  for  several  other  blood  cancer
indications focused on orphan indications.

We  also  believe  that  the  platform  nature  of  our  technologies  should  allow  us  to  pursue  additional  drug  candidates  by  leveraging

certain existing and future scientific data to be developed under our PolyXen® and ImuXen® technology programs.

Xenetic Corporate Programs

PSA-EPO-06: Xenetic ErepoXen® Clinical Trial

This  is  designed  to  be  an  ICH  compliant  Phase  II  open  label  clinical,  sequential  multiple  dose  finding  study  for  subcutaneously
administered  PSA-EPO  in  CKD  patients  not  on  dialysis  and  not  receiving  erythropoiesis  stimulating  agents.  It  is  being  conducted  in
Australia and New Zealand. Patients with hemoglobin levels between 8 and 10 grams per deciliter (“g/dL”) were given the drug candidate
once  every  two  weeks.  If  the  hemoglobin  level  increases  to  between  10  and  12  g/dL,  the  patient  is  moved  to  once  every  four  weeks
administration. The patient’s pharmacodynamic, pharmacokinetic and immunogenic parameters are followed for the duration of the trial.
Dose levels in an escalating form will then be administered. Safety and other parameters will be examined at the end of each dosing cohort
before  moving  onto  the  next  dose  level.  The  first  two  cohorts  of  patients  have  been  completed.  There  were  no  Serious Adverse  Events
(“SAEs”) attributable to PSA-EPO reported thus far. The third cohort of patients at a higher dose level is in progress. The endpoint is to
determine a dose of PSA-EPO that is safe and will move the patient’s hemoglobin level into the 10 to 12 g/dL range.

The  costs  for  this  trial  are  being  borne  by  the  Company.  Costs  will  be  dependent  on  how  many  cohorts  will  be  treated.  The  final
results  from  the  second  cohort  are  expected  to  be  reported  during  the  first  half  of  2015.  Clinical  material  was  manufactured  for  the
Company by Serum Institute. The trial is being run by Novotech Pty Limited (“Novotech”) of Australia.

ONC-AML-01: Xenetic OncoHist™ Clinical Trial

The Company expects to submit an IND filing for Phase I/II(a) clinical trials for AML to the FDA and commence clinical trials, but
not before the end of 2015. We expect this to be an open label increasing dose ranging study to assess the safety, tolerability and efficacy of
OncoHist™ for adult patients with refractory or relapsed AML. This trial will be conducted in the US. Data from the previously completed
work by Saarland University’s Phase I clinical trial and the SynBio clinical trials will be used to aid in the design of the clinical protocol.
We expect the Phase I/II(a) clinical trial material to be produced by a cGMP compliant manufacturing facility. Selection of the Clinical
Research Organization (“CRO”) to run the trial is in progress.

The  costs  for  the  clinical  trial  are  being  borne  by  the  Company.  The  Company  will  need  to  raise  additional  capital  prior  to
commencing  Phase  I/II(a)  clinical  trials.  The  OncoHist™  technology  was  acquired  as  part  of  the  Company’s  acquisition  of  SymbioTec
GmbH (“SymbioTec”) in January 2012 and was valued at $9.6 million as of the acquisition date.

Xenetic Collaborative Partner Programs

Under  the  terms  of  the  relevant  license  agreements  with  the  various  parties,  the  Company  provides  neither  capital  nor  human
resources to the clinical developments of the various product candidates thus licensed for development by our collaborative partners whose
sole responsibility is to meet the timelines associated with each program.   We use the data generated from these jurisdictions as a means of
understanding the clinical validity-human response of the drug before pursuing FDA and EMA trials, this having been a long-established
development  strategy  for  the  Company  as  a  means  of  maximizing  the  development  potential  of  the  Company’s  product  pipeline  while
minimizing the capital exposure associated with such objective.

Notwithstanding  that  there  has  been  a  history  of  delays  in  the  clinical  programs  being  pursued  by  our  partners  in  both  Russia  and
India, based on the data that has been available to us, we have accomplished this objective with both OncoHist™ and ErepoXen®, the two
product  candidates  which  are  currently  the  primary  focus  of  our  efforts  and  upon  which  we  are  now  devoting  our  capital  and  human
resources.  Accordingly, any program delays on these candidates outside the purview of the FDA or EMA will not have a negative impact
on the Company pipeline.

PSA-FVIII: Baxter Factor VIII Pre-Clinical Program

PSA-recombinant Factor VIII has been developed as a long acting therapeutic to treat hemophilia A. Baxter is running this program,

which is in the IND development phase. Baxter has agreed to meet strict due diligence time milestones based on: Clinical Trial
Authorization submission in respect of Phase I/II clinical trials, Final Clinical Study Report Phase I/II and BLA submission all by fixed
dates per the contract. The total cost of this program is being borne by Baxter. There can be no assurance if or when Baxter will actually
achieve any of these due diligence milestones. We expect Baxter will file an IND for clinical trials in the US or Europe during the first half
of 2016. The stated goal of Baxter is to have a significantly longer-acting FVIII to remain the world’s leader in Hemophilia therapies.

PMO-CF-01: Pharmsynthez PulmoXen™ Clinical Trial

This is a Phase I(a) open label two dose safety study for inhaled PSA-DNase 1 in healthy volunteers and has been completed and
reported on April 7, 2014. The study is being conducted in Russia. No adverse events were reported so far and lung function was reported
to  be  normal. A  clinical  trial  with  CF  patients  is  in  start-up  stage  (regulatory  applications).  The  total  cost  of  the  trial  is  being  borne  by
Pharmsynthez. The trial is being run by a partner-sponsored CRO in Russia, Belarus and Ukraine.

If and when satisfactory human clinical data comes out of this collaboration, and provided that the Company is sufficiently confident
that the drug candidate is well-tolerated and effective for this indication, the Company plans to pursue its own development program for
this candidate. However, the Company would have to raise additional capital to pursue its own development of this drug candidate.

IMU-MS-01: Pharmsynthez MyeloXen™ Clinical Trial (Multiple Sclerosis)

This  was  a  Phase  I  open  label  clinical  sequential  dose  finding  study  for  subcutaneously  administered  MyeloXen™  (liposomes
containing peptides for basic myelin protein) in healthy volunteers and patients. This was a proof-of-concept study to show the influence of
MyeloXen™ on catalytic anti-MBP levels and activities. The study was conducted in Russia and is complete. The study report is under
final review to be submitted to the Russian MoH. The total cost for the clinical trial was borne by Pharmsynthez. The clinical material was
manufactured by Pharmsynthez. The clinical trial was run by a partner-sponsored CRO in Russia.

If and when satisfactory clinical patient data comes out of this collaboration that provides the Company a level of comfort that the
drug candidate is well-tolerated and effective, the Company plans to pursue its own development program for this candidate. However, the
Company would have to raise additional capital to pursue its own development of this drug candidate.

PSA-EPO-03: Serum Institute ErepoXen® Clinical Trial

This  is  a  Phase  II(a)  open  label  clinical,  sequential  single  dose  finding  study  for  intravenously  administered  PSA-EPO  for  CKD
patients who are on dialysis. This trial follows the successful completion of two subcutaneous PSA-EPO clinical trials in India. The first
was a Phase I single dose range finding study for subcutaneously administered PSA-EPO in healthy volunteers. The second was a Phase II
single dose range finding study for subcutaneously administered PSA-EPO in CKD patients not on dialysis. All trials are being conducted
in India. The first two cohorts of patients have been completed. There were no Serious Adverse Events (“SAEs”) attributable to PSA-EPO
reported thus far. The third cohort of patients at a higher dose level is in progress. The endpoint of the trial is to determine the maximum
tolerated  single  dose  of  PSA-EPO.  The  total  cost  of  the  clinical  trial  is  being  borne  by  Serum  Institute  and  the  clinical  material  was
manufactured by Serum Institute. The clinical trial is being run by a partner-sponsored CRO in India.

PSA-EPO-05: SynBio ErepoXen® (Epolong) Clinical Trial

This  is  a  Phase  II(b)/III  open  label  clinical,  randomized,  comparative,  multiple  dose  study  for  subcutaneously  administered
ErepoXen® in CKD patients not on dialysis and not receiving erythropoiesis stimulating agents. Patients are compared to a control arm
with Aranesp® (darbepoetin alfa). The study is being conducted in the Russian Federation and is currently in progress. In 2014, a protocol
amendment was implemented and the starting dose was increased based on interim data and the data monitoring board decision. The new
protocol amendment is ready to be submitted to the Russian Ministry of Health (the “Russian MoH”). The total cost for this clinical trial is
being borne by SynBio. The clinical material was manufactured by Serum Institute. The clinical trial is being run by a partner-sponsored
CRO in Russia.

ONC-AML-02: SynBio Arahist-09 Clinical Trial

This  was  a  Phase  II  open  label  two  dose  level,  randomized  comparative  study  to  assess  the  safety,  tolerability  and  efficacy  of
OncoHist™ in combination with HAM (high dose cytarabine chemotherapy) in adult patients with refractory or early relapsed AML. This
study was conducted in Russia. Patients received one cycle of HAM regimen (one week) and one cycle of OncoHist™ regimen (three times
per week for three weeks). The HAM regimen was based on the then current standard of care in Russia. This standard of care was changed
by the Russian Ministry of Health. The study has be stopped and the study report is currently in progress. The total cost of the trial was
borne by SynBio. The clinical material for this OncoHist™ trial was manufactured at the Shemyakin Institute in Moscow for SynBio. The
trial was run by a partner-sponsored CRO in Russia.

ONC-NHL-01: SynBio Anahoret Clinical Trial

This was a Phase II open label increasing dose ranging study to assess the safety, tolerability and efficacy of OncoHist™ as a single
agent  in  treating  NHL.  This  study  was  conducted  in  Russia.  The  trial  is  complete  and  the  report  submitted  to  the  Russian  MoH.  It  was
shown  that  OncoHist™  was  well  tolerated  in  this  trial.  The  total  cost  of  the  trial  was  borne  by  SynBio.  The  clinical  OncoHist™  drug
product was manufactured at the Shemyakin Institute in Moscow for SynBio. The trial was run by a partner-sponsored CRO in Russia.

If and when satisfactory clinical patient data comes out of this collaboration that provides the Company a level of comfort that the
drug candidate is well-tolerated and effective, the Company plans pursue its own development program for this candidate. However, the
Company would have to raise additional capital to pursue its own development of this drug candidate.

Patents and Proprietary Rights

The Company has several drug product candidates under development, each protected by patent and pending patent applications in

the United States and the rest of the world.

Xenetic  has  received  patent  protection  for  several  therapeutics  that  have  been  linked  to  a  polysialic  acid.    These  include  PSA-
erythropoietin, PSA-insulin and PSA-insulin like protein, PSA-Factor VIII, PSA-DNAse I and PSA-granulocyte colony stimulating factor. 
Further Xenetic’s portfolio includes patents cover methods to prepare proteins that are linked to a polysialic acid.  These patents include
coverage for linking a PSA to a protein in a high pH solution and through a process for producing an aldehyde derivative of a sialic acid
through the opening and oxidation of a sialic acid unit.  The linkage can be at the N-terminus.

Xenetic has received patent protection for the production of PSA and the removal of endotoxin during the purification process.  The
removal  of  endotoxin  occurs  through,  for  instance,  the  addition  of  a  high  pH  solution  to  the  PSA  and  through  a  process  to  separate  a
polydisperse  ionically  charged  polysaccharide,  such  as  PSA,  into  fractions  of  different  average  molecular  weight  through  the  use,  for
instance, of a column and elution buffers with different and constant ionic strength and/or pH, resulting in a fractionated polysaccharide that
has a molecular weight polydispersity of 1.1 or lower.

16

 
 
 
 
 
 
 
 
 
 
 
 
 
Xenetic  also  has  patents  that  cover  its  OncoHist™  product.    These  include  recently  allowed  patents  covering  the  OncoHist™
composition and claims for the use of OncoHist™ to treat cancer, including leukemia. The OncoHist™ portfolio also includes patents that
cover the use of a histone protein as an antibiotic and to threat thrombocytopenia and further as an antimicrobial component of a personal
care product.

The  Company’s  portfolio  also  includes  in-licensed  patents  from  Ploughshare  Innovations,  a  licensing  arm  of  the  United  Kingdom
Department of Defense, in connection with MyeloXen™ technology. The Company has no current clinical development efforts ongoing at
this time that fall within the bounds of the Ploughshare Innovations in-license. To the extent that such efforts are ongoing, such efforts are
being  undertaken  by  a  collaborative  partner,  though  the  rights  under  the  in-license  (e.g.  for  the  patents)  lie  with  the  Company  and  are
subject to a sublicense provided to the collaborative partner. This includes a method used to entrap a water soluble drug within a liposome
when the drug is mixed with a mono or disaccharide.  This patent portfolio fits well with the Company’s liposome patents and pending
applications that include those that cover using liposomes with an entrapped complex of a DNA operatively encoding antigen to induce an
immune response in a human or animal and methods to form liposomes.

The Company currently owns 147 US and international patents and over 90 pending patent applications that cover various aspects of
our  technologies.  We  have  filed  patent  applications,  and  plan  to  file  additional  patent  applications,  covering  various  aspects  of  our
PolyXen®  technology  platform  covering  polysialylation  and  advanced  polymer  conjugate  technologies,  as  well  as  proprietary  product
candidates  including  ErepoXen®  and  PulmoXen™. Additionally,  our  patents  and  patent  applications  cover  polymer  architecture,  drug
conjugates, formulations, methods of manufacturing polymers and polymer conjugates and methods of administering polymer conjugates.
In addition, our patent portfolio contains patents and patent applications that encompass our OncoHist™ technology platform including use
of histones for the treatment of different cancers. The OncoHist™ patent portfolio, acquired as part of our acquisition of SymbioTec GmbH
in January 2012, includes OncoHist™, a bis-Met histone. Our patent strategy is to file patent applications on innovations and improvements
to  cover  a  significant  majority  of  the  major  pharmaceutical  markets  in  the  world.  Generally,  patents  have  a  term  of  20  years  from  the
earliest priority date (assuming all maintenance fees are paid). In some instances, patent terms can be increased or decreased, depending on
the laws and regulations of the country or jurisdiction that issued the patent.

We  also  rely  on  trade  secret  protection  for  our  confidential  and  proprietary  information.  No  assurance  can  be  given  that  we  can
meaningfully protect our trade secrets. Others may independently develop substantially equivalent confidential and proprietary information
or otherwise gain access to, or disclose, our trade secrets. Thus, while we rely on trade secret protection and other unpatented proprietary
rights for important proprietary technologies, any loss of such rights could harm our business, results of operations and financial condition.

In  certain  situations  where  we  work  with  drugs  covered  by  one  or  more  patents,  our  ability  to  develop  and  commercialize  our
technologies  may  be  affected  by  limitations  in  our  access  to  these  proprietary  drugs.  Even  if  we  believe  we  are  free  to  work  with  a
proprietary  drug,  we  cannot  guarantee  that  we  will  not  be  accused  of,  or  be  determined  to  be,  infringing  a  third  party’s  rights  and  be
prohibited from working with the drug or found liable for damages. Any such restriction on access or liability for damages would have a
material adverse effect on our business, results of operations and financial condition.

The  patent  positions  of  pharmaceutical  and  biotechnology  companies,  such  as  ours,  are  uncertain  and  involve  complex  legal  and
factual issues. There can be no assurance that patents that have issued will be held valid and enforceable in a court of law. Even for patents
that are held valid and enforceable, the legal process associated with obtaining such a judgment is time consuming and costly. Additionally,
issued patents can be subject to opposition or other proceedings that can result in the revocation of the patent or maintenance of the patent
in  amended  form  (and  potentially  in  a  form  that  renders  the  patent  without  commercially  relevant  and/or  broad  coverage).  Further,  our
competitors  may  be  able  to  circumvent  and  otherwise  design  around  our  patents.  Even  if  a  patent  is  issued  and  enforceable,  because
development and commercialization of pharmaceutical products can be subject to substantial delays, patents may expire early and provide
only  a  short  period  of  protection,  if  any,  following  the  commercialization  of  a  products  encompassed  by  our  patent(s).  We  may  have  to
participate in interference proceedings declared by the U.S. Patent and Trademark Office, which could result in a loss of the patent and/or
substantial cost to us. Further, we understand that if any of our pending patent applications do not issue, or are deemed invalid following
issuance, we may lose valuable IP protection.

17

 
 
 
 
 
 
 
 
US  and  foreign  patent  rights  and  other  proprietary  rights  exist  that  are  owned  by  third  parties  and  relate  to  pharmaceutical
compositions  and  reagents,  medical  devices  and  equipment  and  methods  for  preparation,  packaging  and  delivery  of  pharmaceutical
compositions.  We  cannot  predict  with  any  certainty  which,  if  any,  of  these  rights  will  be  considered  relevant  to  our  technology  by
authorities in the various jurisdictions where such rights exist, nor can we predict with certainty which, if any, of these rights will or may be
asserted  against  us  by  third  parties.  We  could  incur  substantial  costs  in  defending  ourselves  and  our  partners  against  any  such  claims.
Furthermore, parties making such claims may be able to obtain injunctive or other equitable relief, which could effectively block our ability
to  develop  or  commercialize  some  or  all  of  our  products  in  the  US  and  in  other  countries  and  could  result  in  the  award  of  substantial
damages. In the event of a claim of infringement, we or our partners may be required to obtain one or more licenses from third parties.
There can be no assurance that we can obtain a license to any technology that we determine we require on reasonable terms, if at all, or that
we could develop or otherwise obtain alternative technology. The failure to obtain licenses, if required, may have a material adverse effect
on our business, results of operations and financial condition. Further, we may not be able to obtain IP licenses related to the development
of our drug candidates on a commercially reasonable basis, if at all.

It is our policy to require our employees and consultants, outside scientific collaborators, sponsored researchers and other advisors
who receive confidential information from us to execute confidentiality agreements upon the commencement of employment or consulting
relationships  with  us.  These  agreements  provide  that  all  confidential  information  developed  or  made  known  to  the  individual  during  the
course of the individual’s relationship with us is to be kept confidential and not disclosed to third parties except in specific circumstances.
The agreements provide that all inventions conceived by an employee shall be our property. There can be no assurance, however, that these
agreements will provide meaningful protection or adequate remedies for our trade secrets in the event of unauthorized use or disclosure of
such information.

Manufacturing and Supply

The Company does not maintain the capability to manufacture its own material necessary to support its drug candidate development
programs nor does it intend to acquire such capability as part of its present business strategy. The Company currently has agreements in
place with Serum Institute whereby Serum Institute produces clinical materials for use in the development of drug candidates involving our
PolyXen® technology. The Company is currently dependent on SynBio for clinical materials with respect to its OncoHist™ AML research
programs. The Company is investigating second source alternative suppliers for its clinical materials. There can be no assurance that it will
be successful or that if a second source is secured that it would be available on commercially reasonable terms or in a timely fashion should
any disruption in supply from Serum Institute or SynBio occur.

Government Regulation

General

The  development,  testing,  manufacture,  labeling,  marketing,  and  promotion  of  any  drug,  including  all  of  our  drug  candidates,  are
subject to extensive regulation in the US by the FDA under the Federal Food, Drug and Cosmetic Act and by other federal, state, local and
foreign government laws and regulations including in the UK, Germany, Russia and other countries in which we conduct business.

18

 
 
 
 
 
 
 
 
 
The NDA Review Process

The steps ordinarily required before a new drug, that is subject to NDA approval, may be marketed in the US include pre-clinical
laboratory tests, further relevant testing, formulation studies, the submission to the FDA of an IND filing (which must become effective
before  clinical  testing  may  commence)  and  adequate  and  well  controlled  clinical  trials  on  human  subjects  to  establish  the  safety  and
effectiveness  of  the  drug  for  each  indication  for  which  FDA  approval  is  sought.  Satisfaction  of  FDA  pre-market  approval  requirements
typically  takes  several  years  and  the  actual  time  required  may  vary  substantially  based  upon  the  type,  complexity  and  novelty  of  the
product, disease or condition for which the new drug is indicated.

Government  regulation  may  delay  or  prevent  marketing  of  potential  products  for  a  considerable  period  of  time  and  requires
substantial time, effort and financial resources on the part of a manufacturer. Success in early stage clinical trials does not assure success in
later stage clinical trials. Data obtained from clinical activities is not always conclusive and may be susceptible to varying interpretations
that  could  delay,  limit,  or  prevent  regulatory  approval.  Even  if  a  product  receives  regulatory  approval,  later  discovery  of  previously
unknown problems with a product may result in restrictions on the product or even complete withdrawal of the product from the market.

Pre-clinical tests include laboratory evaluation of product chemistry and formulation, as well as additional relevant trials to assess the
potential safety and efficacy of the product. The conduct of the pre-clinical tests and formulation of compounds for testing must comply
with federal regulations and requirements. The results of pre-clinical testing are submitted to the FDA as part of an IND.

A 30 day waiting period after the filing of each IND is required prior to the commencement of clinical testing in humans. If the FDA
has not commented on or questioned the IND within this 30 day period, clinical trials may begin. If the FDA has comments or questions,
the questions must be answered to the satisfaction of the FDA before initial clinical testing can begin. In addition the FDA  may,  at  any
time, impose a clinical hold on ongoing clinical trials. If the FDA imposes a clinical hold, clinical trials cannot commence or recommence
without FDA authorization and then only under terms authorized by the FDA. In some instances, the IND process can result in substantial
delay and expense.

Clinical  trials  typically  involve  the  administration  of  the  IND  to  volunteers  or  patients  under  the  supervision  of  a  qualified
investigator.  Clinical  trials  must  be  conducted  in  compliance  with  federal  regulations  and  requirements,  under  protocols  detailing  the
objectives of the trial and the parameters to be used in monitoring safety and effectiveness. Each protocol involving testing on US subjects
must be submitted to the FDA as part of the IND. The study protocol and informed consent information for patients in clinical trials must
also be approved by the Institutional Review Board at each institution where the trials will be conducted.

Clinical  trials  to  support  NDAs  for  marketing  approval  are  typically  conducted  in  three  sequential  phases,  but  the  phases  may
overlap.  In  Phase  I,  the  initial  introduction  of  the  drug  into  healthy  human  subjects  or  patients,  the  drug  is  tested  to  assess  metabolism,
pharmacokinetics and pharmacological actions and safety, including side effects associated with increasing doses. Phase II usually involves
trials in limited patient populations to determine dosage tolerance and optimum dosage, identify possible adverse effects and safety risks,
and  provide  preliminary  support  for  the  efficacy  of  the  drug  in  the  indication  being  studied.  If  a  compound  demonstrates  evidence  of
effectiveness and an acceptable safety profile in Phase II evaluations, Phase III trials are undertaken to further evaluate clinical efficacy and
to further test for safety within an expanded patient population, typically at geographically dispersed clinical trial sites. It is possible that
Phase I, Phase II, or Phase III testing of product candidates may not be completed successfully within any specified time period, if at all.

19

 
 
 
 
 
 
 
 
 
After successful completion of the required clinical testing, generally an NDA is prepared and submitted to the FDA. FDA approval
of the NDA is required before marketing of the product may begin in the US. The NDA must include the results of extensive clinical and
other testing and a compilation of data relating to the product's pharmacology, chemistry, manufacture, and controls. The cost of preparing
and submitting an NDA is substantial. Under federal law, the submission of an NDA is additionally subject to a substantial application user
fee (unless eligible for a waiver or reduction), which currently range from $1,084,550 to $2,169,100, and the manufacturer and/or sponsor
under  an  approved  NDA  are  also  subject  to  annual  product  and  establishment  user  fees,  currently  exceeding  $104,000  per  product  and
$554,000 per establishment. These fees are typically increased annually.

The  FDA  has  60  days  from  its  receipt  of  an  NDA  to  determine  whether  the  application  will  be  accepted  for  filing  based  on  the
agency's threshold determination that the NDA is sufficiently complete to permit substantive review. Once the submission is accepted for
filing, the FDA begins an in-depth review of the NDA. Under federal law, the FDA has agreed to certain performance goals in the review
of NDAs. The user fee goal for review of most non-priority applications is ten months. However, the review process is often significantly
extended by FDA requests for additional information or clarification of information already provided in the submission. The FDA may also
refer applications for novel drug products or drug products which present difficult questions of safety or efficacy to an advisory committee,
typically  a  panel  that  includes  clinicians  and  other  experts,  for  review,  evaluation,  and  a  recommendation  as  to  whether  the  application
should be approved. The FDA is not bound by the recommendation of an advisory committee.

If FDA evaluations of the NDA and the manufacturing facilities and procedures, which typically involves an FDA on-site inspection,
are favorable, the FDA may issue an approval letter or, in some cases, an approvable letter followed by an approval letter. An approvable
letter generally contains a statement of specific conditions that must be met in order to secure final approval of the NDA. If and when those
conditions  have  been  met  to  the  FDA's  satisfaction,  the  FDA  will  typically  issue  an  approval  letter.  An  approval  letter  authorizes
commercial  marketing  of  the  drug  with  specific  prescribing  information  for  specific  indications  in  an  approved  label.  If  the  FDA's
evaluation  of  the  NDA  submission  or  manufacturing  facilities  is  not  favorable,  the  FDA  may  refuse  to  approve  the  NDA  or  issue  a  not
approvable letter. The not approvable letter outlines the deficiencies in the submission and often requires additional testing or information
in order for the FDA to reconsider the application. Even with submission of this additional information, the FDA ultimately may decide
that  the  application  does  not  satisfy  the  regulatory  criteria  for  approval.  With  limited  exceptions,  the  FDA  may  withhold  approval  of  an
NDA regardless of prior advice it may have provided or commitments it may have made to the sponsor. As a condition of NDA approval,
the  FDA  may  require  post-approval  testing  and  surveillance  to  monitor  the  drug's  safety  or  efficacy  and  may  impose  other  conditions,
including  labeling  restrictions.  Such  labeling  restrictions  can  materially  impact  the  potential  market  and  profitability  of  the  drug.  Once
granted,  product  approvals  can  still  be  withdrawn  if  compliance  with  regulatory  standards  is  not  maintained  or  problems  are  identified
following initial marketing.

Once the NDA is approved, a product will be subject to certain post-approval requirements, including requirements for adverse event
reporting and submission of periodic reports. Persons responsible for manufacture or distribution are subject to FDA inspections to assess
compliance  with  applicable  statutory  and  regulatory  requirements.  The  Food  and  Drug Administration Amendments Act  of  2007  also
provides the FDA enhanced post-marketing authority, including the authority to require post-marketing studies and clinical trials, labeling
changes based on new safety information, and compliance with risk evaluations and mitigation strategies approved by the FDA.

20

 
 
 
 
 
 
Additionally,  the  FDA  also  strictly  regulates  the  promotional  claims  that  may  be  made  about  drug  products.  The  FDA  requires
substantiation of any claims of superiority of one product over another including, in many cases, requirements that such claims be proven
by adequate and well controlled head-to-head clinical trials. To the extent that market acceptance of the Company’s products may depend
on their superiority over existing therapies, any restriction imposed by FDA on the Company’s ability to advertise or otherwise promote
claims of superiority, or requirements to conduct additional expensive clinical trials to provide proof of such claims, could negatively affect
the sales of the Company's products and/or its costs.

Orphan Drug Act

The Orphan Drug Act provides incentives to manufacturers to develop and market drugs for rare diseases and conditions affecting
fewer  than  200,000  persons  in  the  US  at  the  time  of  application  for  Orphan  Drug  Designation.  The  first  developer  to  receive  FDA
marketing approval for an orphan drug is entitled to a seven year exclusive marketing period in the US for that product. However, a drug
that the FDA considers to be clinically superior to, or different from, another approved orphan drug, even though for the same indication,
may also obtain approval in the US during the seven year exclusive marketing period. In addition, holders of exclusivity for orphan drugs
are expected to assure the availability of sufficient quantities of their orphan drugs to meet the needs of patients. Failure to  do  so  could
result in the withdrawal of marketing exclusivity for the drug.

Legislation  similar  to  the  Orphan  Drug Act  has  been  enacted  in  other  countries  outside  the  US,  including  the  European  Union
(“EU”). The orphan legislation in the EU is available for therapies addressing chronic debilitating or life threatening conditions that affect
five or fewer out of 10,000 persons or are financially not viable to develop. The market exclusivity period is for ten years, although that
period can be reduced to six years if, at the end of the fifth year, available evidence establishes that the product is sufficiently profitable not
to  justify  maintenance  of  market  exclusivity.  The  market  exclusivity  may  be  extended  to  12  years  if  sponsors  complete  a  pediatric
investigation plan agreed upon with the relevant committee of the EMA.

Pediatric Information

Under the Pediatric Research Equity Act of 2007 (“PREA”), NDAs or BLAs or supplements to NDAs or BLAs must contain data to
assess the safety and effectiveness of the drug for the claimed indication(s) in all relevant pediatric sub-populations and to support dosing
and administration for each pediatric sub-population for which the drug is safe and effective. The FDA may grant deferrals for submission
of data or full or partial waivers. Unless otherwise required by regulation, PREA does not apply to any drug for an indication for which
orphan  drug  designation  has  been  granted.  The  Best  Pharmaceuticals  for  Children Act  (“BPCA”),  provides  sponsors  of  NDAs  with  an
additional six month period of market exclusivity for all unexpired patent or non-patent exclusivity on all forms of the drug containing the
active moiety if the sponsor submits results of pediatric studies specifically requested by the FDA under BPCA within required timeframes.
The Biologics Price Competition and Innovation Act provides sponsors of BLAs an additional six month extension for all unexpired non-
patent market exclusivity on all forms of the biologic containing the active moiety pursuant to the BPCA if the conditions under the BPCA
are met.

21

 
 
 
 
 
 
 
 
Foreign Regulation

In addition to regulations in the US, we are subject to a variety of foreign regulatory requirements governing human clinical trials and
marketing  approval  for  drugs.  The  foreign  regulatory  approval  process  includes  all  of  the  risks  associated  with  FDA  approval  set  forth
above, as well as additional country specific regulations. Whether or not we obtain FDA approval for a product, we must obtain approval of
a product by the comparable regulatory authorities of foreign countries before we can commence clinical trials or marketing of the product
in those countries. The approval process varies from country to country, and the time may be longer or shorter than that required for FDA
approval. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country
to country.

Environmental Regulation

In  addition  to  being  subject  to  extensive  regulation  by  the  FDA,  the  Company  must  also  comply  with  environmental  regulation
insofar as such regulation applies to the Company or its drug candidates. Our costs of compliance with environmental regulation as applied
to similar pharmaceutical companies are minimal, since we do not currently, nor do we intend to, engage in the production of any of our
drug  candidates.  The  Company  currently  uses  unaffiliated  manufacturers  to  produce  all  of  its  drug  candidate  material  and  receive  final
material from such manufacturer, without any involvement on our part in the manufacturing process at any stage of the process.

Although we believe that our safety procedures for using, handling, storing and disposing of our product candidate materials comply
with the environmental standards required by state and federal laws and regulations, we cannot completely eliminate the risk of accidental
contamination or injury from these materials. We do not carry a specific insurance policy to mitigate this risk to us or to the environment.

Employees

At April  10,  2015  the  Company  employed  seven  full  time  persons  and  one  part  time  person.  The  Company  is  not  a  party  to  any
collective bargaining agreement with its employees; nor are any of its employees a member of any labor unions. The Company is subject to
certain statutory and contractual obligations in instances where it terminates UK based employees. These obligations, which are ordinary
and customary in the UK, generally range from one to six months wages for terminated employees and would not be expected to represent a
material adverse effect to the Company.

Competition

We are engaged in a rapidly evolving field. If our drug candidate development reaches the level of commercialization and marketing,
we  expect  to  compete  primarily  with  established  pharmaceutical  companies  such  as  Amgen  Inc.,  Bristol-Myers  Squibb  Company,  F.
Hoffmann-La Roche Ltd, Nektar Therapeutics and others. We also expect to compete with established pharmaceutical companies as well as
academic  institutions  and  other  smaller  pharmaceutical  companies  during  the  drug  development  stage  of  our  progress.  Competition  is
intense and expected to increase.

22

 
 
 
 
 
 
 
 
 
 
 
The  large  and  rapidly  growing  market  for  new  drug  therapies  for  use  in  humans  is  likely  to  attract  new  entrants.  Numerous
biotechnology  and  pharmaceutical  companies  are  focused  on  developing  new  drug  therapies  and  many  of  these  companies  have  greater
financial  and  other  resources  and  development  capabilities  than  we  do.  Our  competitors  also  have  greater  collective  experience  in
undertaking  pre-clinical  and  clinical  testing  of  products,  obtaining  regulatory  approvals  and  manufacturing  and  marketing  prescription
pharmaceutical  products. Accordingly,  certain  of  these  competitors  may  succeed  in  obtaining  approval  for  drug  products  and  therapies
more rapidly than us.

In addition to competing with universities and other research institutions in the development of drug products, therapies, technologies
and processes, we may compete with other companies in acquiring rights to products or technologies from universities. There can be no
assurance that our products or product candidates will be more effective or achieve greater market acceptance than competitive products, or
that these companies will not succeed in developing products and technologies that are more effective than those being developed for us or
that would render our products and technologies less competitive or obsolete.

Mr. Maguire has been President, Chief Executive Officer and Director of the Company since January 2014 having been appointed
pursuant  to  terms  included  in  the  Company’s  acquisition  of  Xenetic  UK.  Mr.  Maguire  served  with  Xenetic  UK  as  its  Chief  Executive
Officer from April 2004 to the present. His background is in life science and healthcare investment banking and he has advised many US
and European companies on capital raisings and commercial development over his 26 year career. Mr. Maguire began his banking career

ITEM 1A – RISK FACTORS

An investment in shares of our common stock involves a high degree of risk. You should carefully consider the following information
about  these  risks,  together  with  the  other  information  appearing  elsewhere  in  this  Annual  Report  on  Form  10-K,  including  our
consolidated financial statements and related notes hereto, before deciding to invest in our common stock. The occurrence of any of the
following risks could have a material adverse effect on our business, financial condition, results of operations and future growth prospects.
In these circumstances, the market price of our common stock could decline, and you may lose all or part of your investment.

Risks related to our financial condition and capital requirements

We have never been profitable and may never achieve or sustain profitability.

We  do  not  have  any  significant  revenues,  we  have  never  been  profitable  and  we  may  not  achieve  profitability  in  the  foreseeable

future, if at all. Our ability to generate profits in the future will depend on a number of factors, including:

·

Funding the costs relating to the research and development, regulatory approval, commercialization and sale and marketing of
our drug candidates;

Costs of acquiring and developing new drug candidates;

· Market acceptance of our drug candidates;
·
· Ability to bring our drug candidates to market;
· General and administrative costs relating to our operations;
·
·
· Our ability to raise additional capital.

Increases in our research and development costs;
Charges related to purchases of technology or other assets; and

As  of  December  31,  2014,  we  had  an  accumulated  deficit  of  approximately  $76  million.  We  expect  to  incur  additional  operating
losses as we expand our research and development activities and our commercialization, marketing and sales efforts. If we are unable to
generate sufficient revenue from our operations to pay expenses or we are unable to obtain additional financing on commercially reasonable
terms, our business, financial condition and results of operations may be materially and adversely affected.

We have insufficient cash flow to fund our operations beyond the end of April 2015 which raises substantial doubt about our ability to
continue as a going concern beyond that date.

Our total current assets, cash and working capital were approximately $2.8, $2.5 and $0.1 million, respectively at December 31, 2014.
We  estimate  that  we  have  enough  cash  on  hand  to  fund  our  base  business  plan  through  the  end  of April  2015.  We  will  need  to  raise
additional working capital either through equity or debt or a combination of equity and debt during 2014 should we decide to accelerate the
timing of certain research and development programs versus our base business plan.

Our recurring operating losses, past liquidity issues and indebtedness raise substantial doubt about our ability to continue as a going
concern beyond the end of April 2015. Our ability to continue as a going concern and the appropriateness of using the going concern basis
of accounting depends upon, among other things, our ability to generate sufficient cash from operations and financing sources to meet our
obligations.  There  can  be  no  assurance  that  we  will  be  able  to  generate  positive  cash  flows  from  operations.  Further,  there  can  be  no
assurance that we will be able to obtain additional financing or that, even if we do obtain additional financing, it will be on terms that allow
us to continue to fund our current business plan.

Concern about our ability to fund our base business plan beyond the end of April 2015 could adversely affect our ability to attract and
retain key employees and to attract and retain key collaboration partners that could adversely affect our business and adversely impact the
price of our stock. Our ability to meet future obligations will be dependent upon our future performance, which will be subject to financial,
business and other factors affecting our operations, many of which are beyond our control.

26

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
From time to time, we will need to raise additional funding, which may not be available on acceptable terms, or at all. Failure to obtain
this necessary capital when needed may force us to delay, limit or terminate our product development efforts or other operations.

We are currently advancing our product candidates through preclinical or clinical development. Developing these product candidates

is expensive, and our research and development expenses may increase substantially in connection with our ongoing activities.

As a result, from time to time, we may need to seek additional funds, through public or private equity or debt financings, government
or  other  third-party  funding,  marketing  and  distribution  arrangements  and  other  collaborations,  strategic  alliances  and  licensing
arrangements or a combination of these approaches. Raising funds in the current economic environment may present additional challenges.
Even if we believe we have sufficient funds for our current or future operating plans, we may seek additional capital if market conditions
are favorable or if we have specific strategic considerations.

Any  additional  fundraising  efforts  may  divert  our  management  from  their  day-to-day  activities,  which  may  adversely  affect  our
ability  to  develop  and  commercialize  our  product  candidates.  In  addition,  we  cannot  guarantee  that  future  financing  will  be  available  in
sufficient amounts or on terms acceptable to us, if at all. Moreover, the terms of any financing may adversely affect the holdings or the
rights of our stockholders and the issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may
cause the market price of our shares to decline. The sale of additional equity or convertible securities would dilute all of our stockholders.
The incurrence of indebtedness would result in increased fixed payment obligations and we may be required to agree to certain restrictive
covenants,  such  as  limitations  on  our  ability  to  incur  additional  debt,  limitations  on  our  ability  to  acquire,  sell  or  license  intellectual
property rights and other operating restrictions that could adversely impact our ability to conduct our business. We could also be required to
seek funds through arrangements with collaborative partners or otherwise at an earlier stage than otherwise would be desirable and we may
be required to relinquish rights to some of our  technologies  or  product  candidates  or  otherwise  agree  to  terms  unfavorable  to  us,  any  of
which may have a material adverse effect on our business, operating results and prospects.

If we are unable to obtain funding on a timely basis, we may be required to significantly curtail, delay or discontinue one or more of
our  research  or  development  programs  or  be  unable  to  expand  our  operations  or  otherwise  capitalize  on  our  business  opportunities,  as
desired, which could materially affect our business, financial condition and results of operations.

27

 
 
 
 
 
 
 
Risks related to the discovery and development of our product candidates

We are an established operating company in the business of developing biologic drug products. However, given the uncertainty of such
development our business operations may never fully materialize and create value for investors.

We  are  a  company  focused  on  the  development  for  commercialization,  marketing  and  selling  of  pharmaceutical  products.  Our
PolyXen®, OncoHist™ and ImuXen® drug candidates are in the early stages of the regulatory new drug approval process. Our revenues to
date consist primarily of collaboration revenue from a single partner and not from product sales or royalties. We have not yet recognized
significant revenue. You should evaluate the likelihood of financial and operational success in light of the uncertainties and complexities
present in an early stage company, many of which are beyond our control, including:

· Our potential inability to achieve regulatory approval of our drug candidates;
·
The significant investment of capital and other resources necessary to achieve regulatory approval of our drug candidates; and
· Our  potential  inability  to  enter  into  a  successful  marketing  and  distribution  collaboration  or  to  successfully  commercialize,

market and sell our drug candidates when approved, if ever, on our own.

Our operations have been limited to organizing and staffing our company and early stage work in the development and regulatory
process  to  allow  clinical  trials  on  our  drug  candidates.  These  operations  provide  a  limited  basis  for  you  to  assess  our  ability  to
commercialize our drug candidates and the advisability of investing in us.

Our failure to comply with extensive government regulation may significantly affect our operating results.

Our products are subject to extensive regulation by the FDA, as well as other federal, state, local and foreign government laws and
regulations. These regulations may affect many aspects of our operations, including testing, research and development, manufacturing, pre-
market approval, storage, quality control, adverse event reporting, record keeping, product labeling, marketing, advertising and promotion.
Failure to comply with applicable regulatory requirements could, among other things, result in:

Fines;
·
Changes to advertising or claims made;
·
Failure to obtain necessary marketing approvals;
·
Revocation or suspension of regulatory approvals of products;
·
·
Regulatory letters;
· Adverse publicity;
·
· Delay, interruption or suspension of product manufacturing;
·
· Mandated corrective action; and
Civil or criminal sanctions.
·

Suspension of distribution, marketing and sale;

Product seizures or recall;

The  discovery  of  previously  unknown  problems  with  our  initial  and  future  products  may  result  in  other  significant  unexpected

negative or adverse impact to our operations.

28

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We may find it difficult to enroll patients in our clinical studies, which could delay or prevent clinical studies of our product candidates.

Identifying and qualifying patients to participate in clinical studies of our product candidates is critical to our success. The timing of
our  clinical  studies  depends  on  the  speed  at  which  we  can  recruit  patients  to  participate  in  testing  our  product  candidates.  We  may
experience delays. If patients are unwilling to participate in our clinical studies because of negative publicity from adverse events in the
biopharmaceutical  industries  or  for  other  reasons,  including  competitive  clinical  studies  for  similar  patient  populations,  the  timeline  for
recruiting patients, conducting studies and obtaining regulatory approval of potential products may be delayed. These delays could result in
increased costs, delays in advancing our product development, delays in testing the effectiveness of our technology or termination of the
clinical studies altogether.

We may not be able to identify, recruit and enroll a sufficient number of patients, or those with required or desired characteristics to

achieve diversity in a study, to complete our clinical studies in a timely manner. Patient enrollment is affected by factors including:

Severity of the disease under investigation;

·
· Design of the study protocol;
Size of the patient population;
·
Eligibility criteria for the study in question;
·
Perceived risks and benefits of the product candidate under study;
·
·
Proximity and availability of clinical study sites for prospective patients;
· Availability of competing products and clinical studies;
Efforts to facilitate timely enrollment in clinical studies;
·
·
Patient referral practices of physicians; and
· Ability to monitor patients adequately during and after treatment.

We may not be able to initiate or continue clinical studies if we cannot enroll a sufficient number of eligible patients to participate in
the  clinical  studies  required  by  the  FDA  or  other  regulatory  agencies.  Our  ability  to  successfully  initiate,  enroll  and  complete  a  clinical
study in any foreign country is subject to numerous risks unique to conducting business in foreign countries, including:

· Difficulty in establishing or managing relationships with contract research organizations, and physicians;
· Different standards for the conduct of clinical studies;
· Our inability to locate qualified local consultants, physicians and partners; and
·

The potential burden of complying with a variety of foreign laws, medical standards and regulatory requirements, including the
regulation of pharmaceutical and biotechnology products and treatment.

If we have difficulty enrolling a sufficient number of patients to conduct our clinical studies as planned, we may need to delay, limit

or terminate ongoing or planned clinical studies, any of which would have an adverse effect on our business.

29

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We may encounter substantial delays in our clinical studies.

Clinical  testing  is  expensive,  time-consuming  and  uncertain  as  to  outcome.  We  cannot  guarantee  that  any  clinical  studies  will  be
conducted as planned or completed on schedule, if at all. A failure of one or more clinical studies can occur at any stage of testing. Events
that may prevent successful or timely completion of clinical development include:

· Delays in reaching a consensus with regulatory agencies on study design;
· Delays in reaching agreement on acceptable terms with prospective CROs and clinical study sites;
· Delays in obtaining required Institutional Review Board, or Institutional Ethics Committee approval at each clinical study site;
· Delays in recruiting suitable patients to participate in our clinical studies;
·
·
·

Imposition of a clinical hold by regulatory agencies, after an inspection of our clinical study operations or study sites;
Failure by our CROs, other third parties or us to adhere to clinical study requirements;
Failure to perform in accordance with the FDA’s good clinical practices (“GCP”), or applicable regulatory requirements in
other countries;

Clinical study sites or patients dropping out of a study;

· Delays in the testing, validation, manufacturing and delivery of our product candidates to the clinical sites;
· Delays in having patients complete participation in a study or return for post-treatment follow-up;
·
· Occurrence of serious adverse events associated with the product candidate that are viewed to outweigh its potential benefits;
·
· Delays related to insufficient working capital.

Changes in regulatory requirements and guidance that require amending or submitting new clinical protocols; or

Any inability to successfully complete preclinical and clinical development could result in additional costs to us or impair our ability
to generate revenues. In addition, if we make manufacturing or formulation changes to our product candidates, we may need to conduct
additional studies to bridge our modified product candidates to earlier versions.

If  the  results  of  our  clinical  studies  are  inconclusive  or  if  there  are  safety  concerns  or  adverse  events  associated  with  our  product

candidates, we may:

Be delayed in obtaining marketing approval for our product candidates, if at all;

·
· Obtain approval for indications or patient populations that are not as broad as intended or desired;
· Obtain approval with labeling that includes significant use or distribution restrictions or safety warnings;
·
·

Be subject to changes with the way the product is administered;
Be required to perform additional clinical studies to support approval or be subject to additional post-marketing testing
requirements;

· Have regulatory authorities withdraw their approval of the product or impose restrictions on its distribution in the form of a

modified risk evaluation and mitigation strategy;
Be subject to the addition of labeling statements, such as warnings or contraindications;
Be sued; or
Experience damage to our reputation.

·
·
·

As described above, any of these events could prevent us from achieving or maintaining market acceptance of our product candidates

and impair our ability to generate revenues.

30

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Clinical  trials  may  fail  to  demonstrate  the  safety  and  efficacy  of  our  product  candidates  and  could  prevent  or  significantly  delay
regulatory approval.

Before receiving NDA approval to commercialize a drug candidate, we must demonstrate to the FDA, with substantial evidence from
well controlled clinical trials, that the drug candidate is both safe and effective. If these trials or future clinical trials are unsuccessful, our
business and reputation would be harmed and our stock price would most likely be adversely affected.

All of our drug candidates are prone to the risks of failure. The results of early stage clinical trials of our drug candidates will not
necessarily predict the results of later stage clinical trials. Drug candidates in later stage clinical trials may fail to show desired safety and
efficacy traits, despite having progressed through initial clinical testing. Even if we believe the data collected from clinical trials of our drug
candidates are promising, these data may not be sufficient to obtain approval from the FDA or other regulators. Pre-clinical and clinical
data can be interpreted in different ways. Accordingly, FDA or other regulatory officials could interpret such data in different ways than we
do which could delay, limit or prevent regulatory approval. The FDA, other regulatory authorities, or we may suspend or terminate clinical
trials at any time. Any failure or significant delay in completing clinical trials for our drug candidates, or in receiving regulatory approval
for the sale of resulting products, may severely harm our business and reputation.

Because of these risks, the research and development efforts of our collaborative partners may not result in any commercially viable
products.  If  a  significant  portion  of  these  development  efforts  is  not  successfully  completed  or,  if  required  regulatory  approvals  are  not
obtained by our partners, or any approved products are not commercially successful, we are not likely to generate significant revenues or
become profitable.

Even if we complete the necessary preclinical and clinical studies, we cannot predict when or if we will obtain regulatory approval to
commercialize a product candidate or the approval may be for a more narrow indication than we expect.

A product cannot be commercialized until the appropriate regulatory authorities have reviewed and approved the product candidate.
Even if our product candidates demonstrate safety and efficacy in clinical studies, the regulatory agencies may not complete their review
processes  in  a  timely  manner,  or  we  may  not  be  able  to  obtain  regulatory  approval. Additional  delays  may  result  if  an  FDA Advisory
Committee  or  other  regulatory  advisory  group  or  authority  recommends  non-approval  or  restrictions  on  approval.  In  addition,  we  may
experience delays or rejections based upon additional government regulation from future legislation or administrative action, or changes in
regulatory agency policy during the period of product development, clinical studies and the review process. Regulatory agencies also may
approve a product candidate for fewer or more limited indications than requested or may grant approval subject to the performance of post-
marketing studies. In addition, regulatory agencies may not approve the labeling claims that are necessary or desirable for the successful
commercialization of our product candidates.

31

 
 
 
 
 
 
 
Even if we obtain regulatory approval for a product candidate, our products will remain subject to regulatory scrutiny.

Even  if  we  obtain  regulatory  approval  in  a  jurisdiction,  the  regulatory  authority  may  still  impose  significant  restrictions  on  the
indicated uses or marketing of our product candidates, or impose ongoing requirements for potentially costly post-approval studies or post-
market surveillance. Additionally, the holder of an approved BLA is obligated to monitor and report adverse events and any failure of a
product  to  meet  the  specifications  in  the  BLA.  The  holder  of  an  approved  BLA  must  also  submit  new  or  supplemental  applications  and
obtain FDA approval for certain changes to the approved product, product labeling or manufacturing process. Advertising and promotional
materials must comply with FDA rules and are subject to FDA review, in addition to other potentially applicable federal and state laws.

In  addition,  product  manufacturers  and  their  facilities  are  subject  to  payment  of  user  fees  and  continual  review  and  periodic
inspections by the FDA and other regulatory authorities for compliance with cGMP, and adherence to commitments made in the BLA. If
we  or  a  regulatory  agency  discovers  previously  unknown  problems  with  a  product  such  as  adverse  events  of  unanticipated  severity  or
frequency, or problems with the facility where the product is manufactured, a regulatory agency may impose restrictions relative to that
product  or  the  manufacturing  facility,  including  requiring  recall  or  withdrawal  of  the  product  from  the  market  or  suspension  of
manufacturing.

If we fail to comply with applicable regulatory requirements following approval of any of our product candidates, a regulatory agency

may:

·
·
·
·
·
·
·

Issue a warning letter asserting that we are in violation of the law;
Seek an injunction or impose civil or criminal penalties or monetary fines;
Suspend or withdraw regulatory approval;
Suspend any ongoing clinical studies;
Refuse to approve a pending marketing application, such as a BLA or supplements to a BLA submitted by us;
Seize product; or
Refuse to allow us to enter into supply contracts, including government contracts.

Any government investigation of alleged violations of law could require us to expend significant time and resources in response and
could  generate  negative  publicity.  The  occurrence  of  any  event  or  penalty  described  above  may  inhibit  our  ability  to  commercialize  our
product candidates and generate revenues.

32

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The commercial success of any current or future product candidate will depend upon the degree of market acceptance by physicians,
patients, third-party payors and others in the medical community.

Even with the requisite approvals, the commercial success of our product candidates will depend in part on the medical community,
patients, and third-party payors accepting our product candidates as medically useful, cost-effective, and safe. Any product that we or our
partners  bring  to  the  market  may  not  gain  market  acceptance  by  physicians,  patients,  third-party  payors  and  others  in  the  medical
community. If these products do not achieve an adequate level of acceptance, we may not generate significant product revenue and may not
become  profitable.  The  degree  of  market  acceptance  of  these  product  candidates,  if  approved  for  commercial  sale,  will  depend  on  a
number of factors, including:

·
·

·
·
·
·
·

The potential efficacy and potential advantages over alternative treatments;
The prevalence and severity of any side effects, including any limitations or warnings contained in a product’s approved
labeling;
Relative convenience and ease of administration;
The willingness of the target patient population to try new products and of physicians to prescribe these products;
The strength of marketing and distribution support and timing of market introduction of competitive products;
Publicity concerning our products or competing products and treatments; and
Sufficient third-party insurance coverage or reimbursement.

Even if a potential product displays a favorable efficacy and safety profile in preclinical and clinical studies, market acceptance of the
product will not be known until after it is launched. Our efforts to educate the medical community and third-party payors on the benefits of
the product candidates may require significant resources and may never be successful.

The commercial potential of a drug candidate in development is difficult to predict. If the market size for a new drug is significantly
smaller than we anticipate, it could significantly and negatively impact our revenue, results of operations and financial condition.

It  is  very  difficult  to  estimate  the  commercial  potential  of  product  candidates  due  to  important  factors  such  as  safety  and  efficacy
compared to other available treatments, including potential generic drug alternatives with similar efficacy profiles, changing standards of
care,  third  party  payer  reimbursement  standards,  patient  and  physician  preferences,  the  availability  of  competitive  alternatives  that  may
emerge either during the long drug development process or after commercial introduction, and the availability of generic versions of our
successful product candidates following approval by government health authorities based on the expiration of regulatory exclusivity or our
inability to prevent generic versions from coming to market by asserting our patents. If due to these factors, or others, the market potential
for a drug candidate is lower than we anticipated, it could significantly and negatively impact the commercial terms of any collaboration
partnership  potential  for  such  drug  candidate  or,  if  we  have  already  entered  into  a  collaboration  for  such  drug  candidate,  the  revenue
potential  from  royalty  and  milestone  payments  could  be  significantly  diminished  which  would  negatively  impact  our  business,  financial
condition and results of operations.

Risks related to our reliance on third parties

Because  we  depend  on  Serum  Institute  and  other  third  parties  to  develop  our  drug  candidates  and  to  manufacture  our  material,  we
could be affected adversely if any of them fail to provide us with sufficient product quantities at acceptable prices.

We  have  no  manufacturing  capability. As  a  result,  we  depend  on  Serum  Institute,  which  in  turn  may  rely  upon  third  parties  to
manufacture our products. Although our strategy is based on leveraging the ability of collaboration partners to develop and manufacture our
products  for  commercialization  in  the  pharmaceutical  marketplace,  we  will  be  dependent  on  collaborations  with  drug  development  and
manufacturing  collaborators.  If  we  are  not  able  to  maintain  existing  collaborative  arrangements  or  establish  new  arrangements  on
commercially acceptable terms, we would be required to undertake product manufacturing and development activities at our own expense.
This would increase our capital requirements or require us to limit the scope of our development activities. Moreover, we have limited or
no  experience  in  conducting  full  scale  bioequivalence  or  other  clinical  studies,  preparing  and  submitting  regulatory  applications,  and
manufacturing and marketing drug products and as such we are reliant on contract parties for such efforts. There can be no assurance that
we will be successful in performing these activities and any failure to perform such activities could have a material adverse effect on our
business, financial condition and results of our operations.

If any of our developmental collaborators breach or terminate their agreements with us or otherwise fail to conduct their collaborative
activities  in  a  timely  manner,  the  pre-clinical  and/or  clinical  development  and/or  commercialization  of  our  product  candidates  will  be
delayed  and  we  would  be  required  to  devote  additional  resources  to  product  development  and  commercialization  or  terminate  certain
development programs. Also, a license relationship may be terminated at the discretion of our collaborator, or at the end of contract terms,
in some cases with only limited notice to us. The termination of the collaborative arrangement could have a material adverse effect on our
business,  financial  condition  and  results  of  operations.  There  also  can  be  no  assurance  that  disputes  will  not  arise  with  respect  to  the
ownership of rights to any technology developed with third parties. These and other possible disagreements with collaborators could lead to
delays in the development or commercialization of our product candidates or could result in litigation or arbitration, which could be time
consuming and expensive and could have a material adverse effect on our business, financial condition and results of operations.

We  and  our  contract  manufacturers  are  subject  to  significant  regulation  with  respect  to  manufacturing  our  products.  The
manufacturing facilities on which we rely may not continue to meet regulatory requirements and have limited capacity.

We currently have relationships with a limited number of suppliers for the manufacturing of our product candidates. Each supplier
may require licenses to manufacture such components if such processes are not owned by the supplier or in the public domain and we may
be unable to transfer or sublicense the intellectual property rights we may have with respect to such activities.

All  entities  involved  in  the  preparation  of  pharmaceutical  products  for  clinical  studies  or  commercial  sale,  including  our  existing
contract manufacturers for our product candidates, are subject to extensive regulation. Components of a finished pharmaceutical product
approved  for  commercial  sale  or  used  in  late-stage  clinical  studies  must  be  manufactured  in  accordance  with  cGMP.  These  regulations
govern  manufacturing  processes  and  procedures  (including  record  keeping)  and  the  implementation  and  operation  of  quality  systems  to
control and assure the quality of investigational products and products approved for sale. Poor control of production processes can lead to
the  introduction  of  adventitious  agents  or  other  contaminants,  or  to  inadvertent  changes  in  the  properties  or  stability  of  our  product
candidates that may not be detectable in final product testing. We or our contract manufacturers must supply all necessary documentation
in support of a BLA on a timely basis and must adhere to the FDA’s good laboratory practices (“GLP”), and cGMP regulations enforced by
the FDA through its facilities inspection program. Our facilities and quality systems and the facilities and quality systems of some or all of
our third-party contractors must pass a pre-approval inspection for compliance with the applicable regulations as a condition of regulatory
approval of our product candidates or any of our other potential products. In addition, the regulatory authorities may, at any time, audit or
inspect a manufacturing facility involved with the preparation of our product candidates or our other potential products or the associated
quality systems for compliance with the regulations applicable to the activities being conducted. If these facilities do not pass a pre-approval
plant inspection, FDA approval of the products will not be granted.

34

 
 
 
 
 
 
 
 
 
The regulatory authorities also may, at any time following approval of a product for sale, audit the manufacturing facilities of our
third-party  contractors.  If  any  such  inspection  or  audit  identifies  a  failure  to  comply  with  applicable  regulations  or  if  a  violation  of  our
product specifications or applicable regulations occurs independent of such an inspection or audit, we or the relevant regulatory authority
may require remedial measures that may be costly and/or time-consuming for us or a third party to implement and that may include the
temporary or permanent suspension of a clinical study or commercial sales or the temporary or permanent closure of a facility. Any such
remedial measures imposed upon us or third parties with whom we contract could materially harm our business.

If  we  or  any  of  our  third-party  manufacturers  fail  to  maintain  regulatory  compliance,  the  FDA  can  impose  regulatory  sanctions
including, among other things, refusal to approve a pending application for a biologic product, or revocation of a pre-existing approval. As
a result, our business, financial condition and results of operations may be materially harmed.

Additionally, if supply from one approved manufacturer is interrupted, there could be a significant disruption in commercial supply.
The number of manufacturers with the necessary manufacturing capabilities is limited. In addition, an alternative manufacturer would need
to be qualified through a BLA supplement which could result in further delay. The regulatory agencies may also require additional studies if
a new manufacturer is relied upon for commercial production. Switching manufacturers may involve substantial costs and is likely to result
in a delay in our desired clinical and commercial timelines.

These  factors  could  cause  the  delay  of  clinical  studies,  regulatory  submissions,  required  approvals  or  commercialization  of  our
product  candidates,  cause  us  to  incur  higher  costs  and  prevent  us  from  commercializing  our  products  successfully.  Furthermore,  if  our
suppliers fail to meet contractual requirements, and we are unable to secure one or more replacement suppliers capable of production at a
substantially equivalent cost, our clinical studies may be delayed or we could lose potential revenue.

35

 
 
 
 
 
 
We  expect  to  rely  on  third  parties  to  conduct,  supervise  and  monitor  our  clinical  studies,  and  if  these  third  parties  perform  in  an
unsatisfactory manner, it may harm our business.

We expect to rely on CROs and clinical study sites to ensure our clinical studies are conducted properly and on time. While we will
have  agreements  governing  their  activities,  we  will  have  limited  influence  over  their  actual  performance.  We  will  control  only  certain
aspects  of  our  CROs’  activities.  Nevertheless,  we  will  be  responsible  for  ensuring  that  each  of  our  clinical  studies  is  conducted  in
accordance with the applicable protocol, legal, regulatory and scientific standards, and our reliance on the CROs does not relieve us of our
regulatory responsibilities.

We and our CROs are required to comply with the FDA’s GCPs for conducting, recording and reporting the results of clinical studies
to  assure  that  the  data  and  reported  results  are  credible  and  accurate  and  that  the  rights,  integrity  and  confidentiality  of  clinical  study
participants  are  protected.  The  FDA  enforces  these  GCPs  through  periodic  inspections  of  study  sponsors,  principal  investigators  and
clinical study sites. If we or our CROs fail to comply with applicable GCPs, the clinical data generated in our future clinical studies may be
deemed unreliable and the FDA may require us to perform additional clinical studies before approving any marketing applications. Upon
inspection, the FDA may determine that our clinical studies did not comply with GCPs. In addition, our future clinical studies will require a
sufficient number of test subjects to evaluate the safety and efficacy of our product candidates. Accordingly, if our CROs fail to comply
with these regulations or fail to recruit a sufficient  number  of  patients,  we  may  be  required  to  repeat  such  clinical  studies,  which  would
delay the regulatory approval process.

Our  CROs  are  not  our  employees,  and  we  are  therefore  unable  to  directly  monitor  whether  or  not  they  devote  sufficient  time  and
resources to our clinical and nonclinical programs, which must be conducted in accordance with GCPs and GLPs, respectively. These CROs
may  also  have  relationships  with  other  commercial  entities,  including  our  competitors,  for  whom  they  may  also  be  conducting  clinical
studies  or  other  drug  development  activities  that  could  harm  our  competitive  position.  If  our  CROs  do  not  successfully  carry  out  their
contractual  duties  or  obligations,  fail  to  meet  expected  deadlines,  or  if  the  quality  or  accuracy  of  the  clinical  data  they  obtain  is
compromised due to the failure to adhere to our clinical protocols or regulatory requirements, or for any other reasons, our clinical studies
may  be  extended,  delayed  or  terminated,  and  we  may  not  be  able  to  obtain  regulatory  approval  for,  or  successfully  commercialize  our
product candidates. As a result, our financial results and the commercial prospects for our product candidates would be harmed, our costs
could increase, and our ability to generate revenues could be delayed.

We  may  also  rely  on  other  third  parties  to  store  and  distribute  our  products  for  any  clinical  studies  that  we  may  conduct. Any
performance  failure  on  the  part  of  our  distributors  could  delay  clinical  development  or  marketing  approval  of  our  product  candidates  or
commercialization of our products, if approved, producing additional losses and depriving us of potential product revenue.

36

 
 
 
 
 
 
 
Our reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will discover them
or that our trade secrets will be misappropriated or disclosed.

Because we rely on third parties to manufacture our product candidates, and because we collaborate with various organizations and
academic institutions on the development of our product candidates, we must, at times, share trade secrets with them. We seek to protect
our proprietary technology in part by entering into confidentiality agreements and, if applicable, material transfer agreements, collaborative
research agreements, consulting agreements or other similar agreements with our collaborators, advisors, employees and consultants prior
to  beginning  research  or  disclosing  proprietary  information.  These  agreements  typically  limit  the  rights  of  the  third  parties  to  use  or
disclose our confidential information, such as trade secrets. Despite the contractual provisions employed when working with third parties,
the  need  to  share  trade  secrets  and  other  confidential  information  increases  the  risk  that  such  trade  secrets  become  known  by  our
competitors, are inadvertently incorporated into the technology of others, or are disclosed or used in violation of these agreements. Given
that our proprietary position is based, in part, on our know-how and trade secrets, a competitor’s discovery of our trade secrets or other
unauthorized use or disclosure would impair our competitive position and may have a material adverse effect on our business.

In addition, these agreements typically restrict the ability of our collaborators, advisors, employees and consultants to publish data
potentially relating to our trade secrets. Our academic collaborators typically have rights to publish data, provided that we are notified in
advance and may delay publication for a specified time in order to secure our intellectual property rights arising from the collaboration. In
other cases, publication rights are controlled exclusively by us, although in some cases we may share these rights with other parties. We
may also conduct joint research and development programs that may require us to share trade secrets under the terms of our research and
development partnerships or similar agreements. Despite our efforts to protect our trade secrets, our competitors may discover our trade
secrets, either through breach of these agreements, independent development or publication of information including our trade secrets in
cases  where  we  do  not  have  proprietary  or  otherwise  protected  rights  at  the  time  of  publication. A  competitor’s  discovery  of  our  trade
secrets would impair our competitive position and have an adverse impact on our business.

Risks related to our intellectual property

If we fail to adequately protect or enforce our IP rights, we may be unable to operate effectively.

Our success and ability to compete are substantially dependent on our patents, proprietary formulations and trademarks. Although we
believe that the patents and associated trademarks and licenses are valid, there can be no assurance that they will not be challenged and
subsequently invalidated and/or canceled. The invalidation or cancellation of any one or all of the patents or trademarks would significantly
damage our commercial prospects.

Further, we may find it necessary to legally challenge parties infringing our patents or trademarks or licensed trademarks to enforce
our  rights  thereto.  There  can  be  no  assurance  that  any  of  the  patents  would  ultimately  be  held  valid  or  that  efforts  to  defend  any  of  the
patents, trade secrets, know-how or other IP rights would be successful.

37

 
 
 
 
 
 
 
 
 
If any of our pending patent applications do not issue or are deemed invalid following issuance, we may lose valuable IP protection.

The  patent  positions  of  pharmaceutical  and  biotechnology  companies,  such  as  ours,  are  uncertain  and  involve  complex  legal  and
factual issues. We own numerous US and foreign patents and a number of pending patent applications that cover various aspects of our
technologies. There can be no assurance that patents that have issued will be held valid and enforceable in a court of law. Even for patents
that are held valid and enforceable, the legal process associated with obtaining such a judgment is time consuming and costly. Additionally,
issued patents can be subject to opposition or other proceedings that can result in the revocation of the patent or maintenance of the patent
in  amended  form  (and  potentially  in  a  form  that  renders  the  patent  without  commercially  relevant  and/or  broad  coverage).  Further,  our
competitors  may  be  able  to  circumvent  and  otherwise  design  around  our  patents.  Even  if  a  patent  is  issued  and  enforceable,  because
development and commercialization of pharmaceutical products can be subject to substantial delays, patents may expire early and provide
only  a  short  period  of  protection,  if  any,  following  the  commercialization  of  a  product  encompassed  by  our  patents.  We  may  have  to
participate in interference proceedings declared by the U.S. Patent and Trademark Office, which could result in a loss of the patent and/or
substantial cost to us.

We have filed patent applications, and plan to file additional patent applications, covering various aspects of our PSA and advanced
polymer conjugate technologies and our proprietary product candidates. There can be no assurance that the patent applications for which
we apply would actually be issued as patents, or do so with commercially relevant and/or broad coverage. The coverage claimed in a patent
application can be significantly reduced before the patent is issued. The scope of our claim coverage can be critical to our ability to enter
into  licensing  transactions  with  third  parties  and  our  right  to  receive  royalties  from  our  collaboration  partnerships.  Since  publication  of
discoveries  in  scientific  or  patent  literature  often  lags  behind  the  date  of  such  discoveries,  we  cannot  be  certain  that  we  were  the  first
inventor  of  inventions  covered  by  our  patents  or  patent  applications.  In  addition,  there  is  no  guarantee  that  we  will  be  the  first  to  file  a
patent application directed to an invention.

An  adverse  outcome  in  any  judicial  proceeding  involving  IP,  including  patents,  could  subject  us  to  significant  liabilities  to  third
parties,  require  disputed  rights  to  be  licensed  from  or  to  third  parties  or  require  us  to  cease  using  the  technology  in  dispute.  In  those
instances where we seek an IP license from another, we may not be able to obtain the license on a commercially reasonable basis, if at all,
thereby raising concerns on our ability to freely commercialize our technologies and/or products.

38

 
 
 
 
 
 
If we infringe on the IP rights of others, our business and profitability may be adversely affected.

Our commercial success will also depend, in part, on us and our collaborative partners not infringing on the patents or proprietary
rights of others. There can be no assurance that the technologies and products used or developed by our collaborative partners and marketed
and sold by us will not infringe such rights. If such infringement occurs and neither we nor our collaborative partner is able to obtain a
license  from  the  relevant  third  party,  we  will  not  be  able  to  continue  the  development,  manufacture,  use,  or  sale  of  any  such  infringing
technology  or  product.  There  can  be  no  assurance  that  necessary  licenses  to  third  party  technology  will  be  available  at  all,  or  on
commercially  reasonable  terms.  In  some  cases,  litigation  or  other  proceedings  may  be  necessary  to  defend  against  or  assert  claims  of
infringement  or  to  determine  the  scope  and  validity  of  the  proprietary  rights  of  third  parties.  Any  potential  litigation  could  result  in
substantial costs to, and diversion of, our resources and could have a material and adverse impact on us. An adverse outcome in any such
litigation or proceeding could subject us to significant liabilities, require us to cease using the subject technology or require us to license the
subject technology from the third party, all of which could have a material adverse effect on our business.

If  we  fail  to  comply  with  our  obligations  in  the  agreements  under  which  we  license  intellectual  property  rights  from  third  parties  or
otherwise experience disruptions to our business relationships with our licensors, we could lose license rights that are important to our
business.

We  are  a  party  to  a  number  of  intellectual  property  license  agreements  that  are  important  to  our  business  and  expect  to  enter  into
additional  license  agreements  in  the  future.  Our  existing  license  agreements  impose,  and  we  expect  that  future  license  agreements  will
impose, various diligence, milestone payment, royalty and other obligations on us. If we fail to comply with our obligations under these
agreements, or we are subject to a bankruptcy, the licensor may have the right to terminate the license, in which event we would not be able
to market products covered by the license.

We may need to obtain licenses from third parties to advance our research, and we have done so from time to time. We may fail to
obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In that event, we may be required to expend significant
time  and  resources  to  develop  or  license  replacement  technology.  If  we  are  unable  to  do  so,  we  may  be  unable  to  develop  the  affected
product candidates, which could harm our business significantly. We cannot provide any assurances that third-party patents do not exist
which might be enforced against our current product candidates or future products, resulting in either an injunction prohibiting the sales, or,
with respect to the sales, an obligation on our part to pay royalties and/or other forms of compensation to third parties.

In many cases, patent prosecution of our licensed technology is controlled solely by the licensor. If our licensors fail to obtain and
maintain patent or other protection for the proprietary intellectual property we license from them, we could lose our rights to the intellectual
property  or  our  exclusivity  with  respect  to  those  rights,  and  our  competitors  could  market  competing  products  using  the  intellectual
property.  In  certain  cases,  we  control  the  prosecution  of  patents  resulting  from  licensed  technology.  In  the  event  we  breach  any  of  our
obligations related to such prosecution, we may incur significant liability to our licensing partners. Licensing of intellectual property is of
critical  importance  to  our  business  and  involves  complex  legal,  business  and  scientific  issues  and  is  complicated  by  the  rapid  pace  of
scientific discovery in our industry. Disputes may arise regarding intellectual property subject to a licensing agreement, including:

39

 
 
 
 
 
 
 
 
·
·

The scope of rights granted under the license agreement and other interpretation-related issues;
The extent to which our technology and processes infringe on intellectual property of the licensor that is not subject to the
licensing agreement;
The sublicensing of patent and other rights under our collaborative development relationships;

·
· Our diligence obligations under the license agreement and what activities satisfy those diligence obligations;
·

The ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and
us and our partners; and
The priority of invention of patented technology.

·

If  disputes  over  intellectual  property  that  we  have  licensed  prevent  or  impair  our  ability  to  maintain  our  current  licensing

arrangements on acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates.

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

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

Interference proceedings provoked by third parties or brought by us may be necessary to determine the priority of inventions with
respect to our patents or patent applications or those of our licensors. An unfavorable outcome could require us to cease using the related
technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer
us a license on commercially reasonable terms. Our defense of litigation or interference proceedings may fail and, even if successful, may
result in substantial costs and distract our management and other employees. We may not be able to prevent, alone or with our licensors,
misappropriation of our intellectual property rights, particularly in countries where the laws may not protect those rights as fully as in the
United States.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk
that  some  of  our  confidential  information  could  be  compromised  by  disclosure  during  this  type  of  litigation.  There  could  also  be  public
announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive
these results to be negative, it could have a material adverse effect on the price of our common stock.

40

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Recent patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and
the enforcement or defense of our issued patents.

On September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law. The Leahy-Smith Act
includes a number of significant changes to U.S. patent law, including provisions that affect the way patent applications will be prosecuted
and  may  also  affect  patent  litigation.  The  U.S.  PTO  is  currently  developing  regulations  and  procedures  to  govern  administration  of  the
Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, and in particular, the first to file
provisions, were enacted March 16, 2013. However, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of
our business. However, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution
of our patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our
business and financial condition.

We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential
information of third parties or that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

We employ individuals who were previously employed at universities or other biotechnology or pharmaceutical companies, including
our competitors or potential competitors. Although we try to ensure that our employees, consultants and independent contractors do not use
the proprietary information or know-how of others in their work for us, we may be subject to claims that we or our employees, consultants
or  independent  contractors  have  inadvertently  or  otherwise  used  or  disclosed  intellectual  property,  including  trade  secrets  or  other
proprietary information, of any of our employee’s former employer or other third parties. Litigation may be necessary to defend against
these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property
rights or personnel, which could adversely impact our business. Even if we are successful in defending against such claims, litigation could
result in substantial costs and be a distraction to management and other employees.

We may be subject to claims challenging the inventorship or ownership of our patents and other intellectual property.

We may also be subject to claims that former employees, collaborators or other third parties have an ownership interest in our patents
or  other  intellectual  property.  We  may  have  in  the  future  ownership  disputes  arising,  for  example,  from  conflicting  obligations  of
consultants or others who are involved in developing our product candidates. Litigation may be necessary to defend against these and other
claims challenging inventorship or ownership. If we fail in defending any such claims, in addition to paying monetary damages, we may
lose valuable intellectual property rights, such as exclusive ownership of, or right to use, valuable intellectual property. Such an outcome
could have a material adverse effect on our business. Even if we are successful in defending against such claims, litigation could result in
substantial costs and be a distraction to management and other employees.

41

 
 
 
 
 
 
 
 
Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment
and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-
compliance with these requirements.

Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or applications will be due
to be paid to the U.S. PTO and various governmental patent agencies outside of the United States in several stages over the lifetime of the
patents  and/or  applications.  The  U.S.  PTO  and  various  non-U.S.  governmental  patent  agencies  require  compliance  with  a  number  of
procedural,  documentary,  fee  payment  and  other  similar  provisions  during  the  patent  application  process.  Non-compliance  may  result  in
abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In
such  an  event,  our  competitors  might  be  able  to  enter  the  market  and  this  circumstance  would  have  a  material  adverse  effect  on  our
business.

Issued patents covering our product candidates could be found invalid or unenforceable if challenged in court.

If we or one of our licensing partners initiated legal proceedings against a third party to enforce a patent covering one of our product
candidates,  the  defendant  could  counterclaim  that  the  patent  covering  our  product  candidate  is  invalid  and/or  unenforceable.  In  patent
litigation in the United States, defendant counterclaims alleging invalidity and/or unenforceability are commonplace. Grounds for a validity
challenge  could  be  an  alleged  failure  to  meet  any  of  several  statutory  requirements,  including  lack  of  novelty,  obviousness  or  non-
enablement.  Grounds  for  an  unenforceability  assertion  could  be  an  allegation  that  someone  connected  with  prosecution  of  the  patent
withheld relevant information from the U.S. PTO, or made a misleading statement, during prosecution. Third parties may also raise similar
claims  before  administrative  bodies  in  the  United  States  or  abroad,  even  outside  the  context  of  litigation.  Such  mechanisms  include  re-
examination, post grant review, and equivalent proceedings in foreign jurisdictions (e.g., opposition proceedings). Such proceedings could
result in revocation or amendment to our patents in such a way that they no longer cover our product candidates. The outcome following
legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity question, for example, we cannot be certain
that there is no invalidating prior art, of which we and the patent examiner were unaware during prosecution. If a defendant were to prevail
on  a  legal  assertion  of  invalidity  and/or  unenforceability,  we  would  lose  at  least  part,  and  perhaps  all,  of  the  patent  protection  on  our
product candidates. Such a loss of patent protection would have a material adverse impact on our business.

Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our products.

As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents.
Obtaining and enforcing patents in the biotechnology industry involve both technological and legal complexity, and is therefore obtaining
and enforcing biotechnology patents is costly, time-consuming and inherently uncertain. In addition, the United States has recently enacted
and  is  currently  implementing  wide-ranging  patent  reform  legislation.  Recent  U.S.  Supreme  Court  rulings  have  narrowed  the  scope  of
patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. In addition to increasing
uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the
value  of  patents,  once  obtained.  Depending  on  decisions  by  the  U.S.  Congress,  the  federal  courts,  and  the  U.S.  PTO,  the  laws  and
regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our
existing patents and patents that we might obtain in the future.

We may not be able to protect our intellectual property rights throughout the world.

Filing,  prosecuting  and  defending  patents  on  product  candidates  in  all  countries  throughout  the  world  would  be  prohibitively
expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United
States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws
in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the
United  States,  or  from  selling  or  importing  products  made  using  our  inventions  in  and  into  the  United  States  or  other  jurisdictions.
Competitors  may  use  our  inventions  in  jurisdictions  where  we  have  not  obtained  patent  protection  to  develop  their  own  products  and
further, may export otherwise infringing products to territories where we have patent protection, but enforcement is not as strong as that in
the United States. These products may compete with our products and our patents or other intellectual property rights may not be effective
or sufficient to prevent them from competing.

Many  companies  have  encountered  significant  problems  in  protecting  and  defending  intellectual  property  rights  in  foreign
jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade
secrets and other intellectual property protection, particularly those relating to biotechnology products, which could make it difficult for us
to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to
enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of
our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and
could  provoke  third  parties  to  assert  claims  against  us.  We  may  not  prevail  in  any  lawsuits  that  we  initiate  and  the  damages  or  other
remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around
the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.

Risks related to our business operations

We operate in an extremely competitive environment and there can be no assurances that competing technologies would not harm our
business development.

We are engaged in a rapidly evolving field. Competition from numerous pharmaceutical companies including Amgen Inc., Bristol-
Myers  Squibb  Company,  F.  Hoffmann-La  Roche  Ltd,  Nektar  Therapeutics  and  others,  as  well  as  research  and  academic  institutions,  is
intense and expected to increase. The large and rapidly growing market for liposomal drugs and oncology treatments is likely to attract new
entrants.  Numerous  biotechnology  and  pharmaceutical  companies  are  focused  on  developing  new  liposomal  drug  delivery  systems  and
cancer treatments. Many, if not all, of these companies have greater financial and other resources and development capabilities than we do.
Many  of  our  competitors  also  have  greater  collective  experience  in  undertaking  pre-clinical  and  clinical  testing  of  products,  obtaining
regulatory  approvals  and  manufacturing  and  marketing  prescription  pharmaceutical  products.  There  can  be  no  assurance  that  our  under
development  drug  candidates  will  be  more  effective  or  achieve  greater  market  acceptance  than  competitive  products,  or  that  our
competitors  will  not  succeed  in  developing  products  and  technologies  that  are  more  effective  than  those  being  developed  by  us  or  that
would render our products and technologies less competitive or obsolete. See “Competition”.

43

 
 
 
 
 
 
 
 
Technological advancements by our competitors could result in the obsolescence of some or all of our drug candidates and may harm
business development.

The areas in which we are developing and commercializing our drug candidates involve rapidly developing technology. There can be
no assurance that we will be able to establish ourselves in such fields, or, if established, that we will be able to maintain our position. There
can be no assurance that the development by others of new or improved drugs will not make our drug candidates superfluous or obsolete.

We are a party to collaboration agreements and other significant agreements which contain complex commercial terms that could result
in disputes, litigation or indemnification liability that could adversely affect our business, results of operations and financial condition.

We  currently  derive,  and  expect  to  derive  in  the  foreseeable  future,  all  of  our  revenue  from  collaboration  agreements  with

biotechnology and pharmaceutical companies. These collaboration agreements contain complex commercial terms, including:

·

·

·

·

·

·

·

·

·

Clinical  development  and  commercialization  obligations  that  are  based  on  certain  commercial  reasonableness  performance
standards that can often be difficult to enforce if disputes arise as to adequacy of our partner’s performance;
Research  and  development  performance  and  reimbursement  obligations  for  our  personnel  and  other  resources  allocated  to
partnered drug candidate development programs;
Clinical and commercial manufacturing agreements, some of which are priced on an actual cost basis for products supplied by
us to our partners with complicated cost allocation formulas and methodologies;
Clinical  development  and  commercialization  obligations  that  are  based  on  certain  commercial  reasonableness  performance
standards that can often be difficult to enforce if disputes arise as to adequacy of our partner’s performance;
Research  and  development  performance  and  reimbursement  obligations  for  our  personnel  and  other  resources  allocated  to
partnered drug candidate development programs;
Clinical and commercial manufacturing agreements, some of which are priced on an actual cost basis for products supplied by
us to our partners with complicated cost allocation formulas and methodologies;
IP ownership allocation between us and our partners for improvements and new inventions developed during the course of the
collaboration;
Royalties on drug sales based on a number of complex variables, including net sales calculations, geography, scope of patent
claim coverage, patent life, generic competitors, bundled pricing and other factors; and
Indemnity obligations for IP infringement, product liability and certain other claims.

From time to time, we have informal dispute resolution discussions with third parties regarding the appropriate interpretation of the
complex  commercial  terms  contained  in  our  agreements.  One  or  more  disputes  may  arise  or  escalate  in  the  future  regarding  our
collaboration  agreements,  transaction  documents,  or  third  party  license  agreements  that  may  ultimately  result  in  costly  litigation  and
unfavorable interpretation of contract terms, which would have a material adverse effect on our business, financial condition and results of
operations.

Write-offs related to the impairments of our long-lived assets, including goodwill and indefinite-lived intangible assets, and other non-
cash charges such as share-based compensation may adversely impact our results of operations.

We may incur significant non-cash charges related to impairments of our long-lived assets, including goodwill and indefinite-lived
intangible assets. Although we did not record any such charges during 2014, we are required to perform periodic impairment reviews of
those assets at least annually. The carrying value of goodwill on our balance sheet that is subject to impairment reviews was approximately
$3.5 million and $3.7 million at December 31, 2014 and 2013, respectively, and the carrying value of our indefinite-lived assets was $9.8
million and $10.3 million at December 31, 2014 and 2013, respectively. To the extent future reviews conclude that the expected future cash
flows generated from our business activities are not sufficient to recover the carrying value of these assets, we will be required to measure
and record an impairment charge to write-down these assets to their realizable values and those impairment charges could be equal to the
entire carrying value.

We completed our last review during the fourth quarter of 2014 and determined that goodwill and indefinite-lived intangible assets
were not impaired as of December 31, 2014. However, there can be no assurance that upon completion of subsequent reviews a material
impairment charge will not be recorded. If future periodic reviews determine that our assets are impaired and a write-down is required, it
will adversely impact our operating results.

We  recorded  non-cash  charges  of  approximately  $702,000  and  $432,000  for  share-based  compensation  during  2014  and  2013,
respectively. In addition, we recorded a non-cash charge of approximately $812,000 in consideration for the performance of services and
termination of a prior collaboration agreement between Lipoxen and FDS in exchange for the Company’s common stock during 2014. In
the future this amount could fluctuate materially as the Company expects to continue to issue share-based compensation awards.

Potential  new  accounting  pronouncements  or  legislative  actions  may  adversely  impact  our  future  financial  position  or  results  of
operations.

Future  changes  in  financial  accounting  standards  may  cause  adverse,  unexpected  fluctuations  in  the  timing  of  the  recognition  of
revenues or expenses, and may affect our financial position or results of operations. New pronouncements may occur in the future and may
cause  us  to  be  required  to  make  changes  in  our  accounting  policies  in  the  future.  Compliance  with  changing  regulation  of  corporate
governance  and  public  disclosure  may  result  in  additional  expenses.  Changing  laws,  regulations  and  standards  relating  to  corporate
governance and public disclosure, including the Sarbanes-Oxley Act of 2002, new SEC regulations, Public Company Accounting Oversight
Board  (“PCAOB”)  pronouncements  and  NASDAQ  rules,  are  creating  uncertainty  for  companies  such  as  ours  and  insurance,  accounting
and auditing costs are high as a result of this uncertainty and other factors.

We are committed to maintaining high standards of corporate governance and public disclosure. As a result, we intend to invest all
reasonably necessary resources to comply with evolving standards, and this investment may result in increased general and administrative
expenses and a diversion of management time and attention from revenue-generating activities to compliance activities.

45

 
 
 
 
 
 
 
 
 
Varying interpretations of existing pronouncements and rules have occurred with frequency.

Varying  interpretations  of  existing  pronouncements  of  accounting  policies  or  accounting  treatments  of  existing  transactions  may

cause us to have to restate previously reported result of operations.

For example, in January 2014 we completed the Acquisition that we determined to be a reverse merger business combination. We
allocated  the  purchase  price  consideration  to  the  assets  acquired  and  liabilities  assumed  at  their  estimated  fair  values  as  of  the  date  of
acquisition. Our determination that the Acquisition meets the criteria for a business combination was based on our best knowledge of the
facts and circumstances surrounding the transaction, and requires the application of our judgment. Changes to this determination will result
in the transaction to be accounted for as a recapitalization, with no goodwill recorded, which could cause a material change in our reported
results of operations and could cause the Company to have to amend prior periodic or other filings with the SEC, at further expense to the
Company.

Our future success depends on our ability to retain key employees, consultants and advisors and to attract, retain and motivate qualified
personnel.

We are highly dependent on principal members of our executive team and key employees, the loss of whose services may adversely
impact the achievement of our objectives. Recruiting and retaining other qualified employees, consultants and advisors for our business,
including scientific and technical personnel, will also be critical to our success. There is currently a shortage of skilled executives in our
industry, which is likely to continue. As a result, competition for skilled personnel is intense and the turnover rate can be high. We may not
be  able  to  attract  and  retain  personnel  on  acceptable  terms  given  the  competition  among  numerous  pharmaceutical  and  biotechnology
companies  for  individuals  with  similar  skill  sets.  In  addition,  failure  to  succeed  in  preclinical  or  clinical  studies  may  make  it  more
challenging  to  recruit  and  retain  qualified  personnel.  The  inability  to  recruit  or  loss  of  the  services  of  any  executive,  key  employee,
consultant or advisor may impede the progress of our research and development objectives.

We  will  need  to  expand  our  organization  and  we  may  experience  difficulties  in  managing  this  growth,  which  could  disrupt  our
operations.

As of April 10, 2015, we had seven full-time employees. As we mature, we may need to expand our full-time employee base and to
hire more consultants and contractors. Our management may need to divert a disproportionate amount of its attention away from our day-
to-day activities and devote a substantial amount of time to managing these growth activities. We may not be able to effectively manage the
expansion of our operations, which may result in weaknesses in our infrastructure, operational mistakes, loss of business opportunities, loss
of employees and reduced productivity among remaining employees. Any future growth could require significant capital expenditures and
may divert financial resources from other projects, such as the development of additional product candidates. If our management is unable
to effectively manage our growth, our expenses may increase more than expected, our ability to generate and/or grow revenues could be
reduced, and we may not be able to implement our business strategy. Our future financial performance and our ability to commercialize
product candidates and compete effectively will depend, in part, on our ability to effectively manage any future growth.

46

 
 
 
 
 
 
 
 
 
Our  employees,  principal  investigators,  consultants  and  commercial  partners  may  engage  in  misconduct  or  other  improper  activities,
including non-compliance with regulatory standards and requirements and insider trading.

We  are  exposed  to  the  risk  of  fraud  or  other  misconduct  by  our  employees,  principal  investigators,  consultants  and  commercial
partners. Misconduct by these parties could include intentional failures to comply with the regulations of the FDA and non-U.S. regulators,
provide  accurate  information  to  the  FDA  and  non-U.S.  regulators,  comply  with  healthcare  fraud  and  abuse  laws  and  regulations  in  the
United  States  and  abroad,  report  financial  information  or  data  accurately  or  disclose  unauthorized  activities  to  us.  In  particular,  sales,
marketing  and  business  arrangements  in  the  healthcare  industry  are  subject  to  extensive  laws  and  regulations  intended  to  prevent  fraud,
misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing,
discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Such misconduct
could also involve the improper use of information obtained in the course of clinical studies, which could result in regulatory sanctions and
cause serious harm to our reputation or could cause regulatory agencies not to approve our product candidates. While we intend to adopt a
comprehensive code of conduct applicable to all of our employees, it is not always possible to identify and deter employee misconduct, and
the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in
protecting  us  from  governmental  investigations  or  other  actions  or  lawsuits  stemming  from  a  failure  to  comply  with  these  laws  or
regulations.  If  any  such  actions  are  instituted  against  us,  and  we  are  not  successful  in  defending  ourselves  or  asserting  our  rights,  those
actions could have a significant impact on our business, including the imposition of significant fines or other sanctions.

We face potential product liability, and, if successful claims are brought against us, we may incur substantial liability and costs. If the
use  of  our  product  candidates  harms  patients,  or  is  perceived  to  harm  patients  even  when  such  harm  is  unrelated  to  our  product
candidates, our regulatory approvals could be revoked or otherwise negatively impacted and we could be subject to costly and damaging
product liability claims.

The use of our product candidates in clinical studies and the sale of any products for which we obtain marketing approval exposes us
to  the  risk  of  product  liability  claims.  Product  liability  claims  might  be  brought  against  us  by  consumers,  healthcare  providers,
pharmaceutical companies or others selling or otherwise coming into contact with our products. There is a risk that our product candidates
may induce adverse events. If we cannot successfully defend against product liability claims, we could incur substantial liability and costs.
In addition, regardless of merit or eventual outcome, product liability claims may result in:

Costs due to related litigation;

Impairment of our business reputation;
·
· Withdrawal of clinical study participants;
·
· Distraction of management’s attention from our primary business;
·
·
· Decreased demand for our product candidates, if approved for commercial sale.

Substantial monetary awards to patients or other claimants;
The inability to commercialize our product candidates’ and

47

 
 
 
 
 
 
 
 
 
 
 
 
 
 
If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur
costs that could have a material adverse effect on the success of our business.

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures
and the handling, use, storage, treatment and disposal of hazardous materials and wastes. Our operations involve the use of hazardous and
flammable materials, including chemicals and biological materials. Our operations also produce hazardous waste products. We generally
contract  with  third  parties  for  the  disposal  of  these  materials  and  wastes.  We  cannot  eliminate  the  risk  of  contamination  or  injury  from
these  materials.  In  the  event  of  contamination  or  injury  resulting  from  our  use  of  hazardous  materials,  we  could  be  held  liable  for  any
resulting damages, and any liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines
and penalties.

Although  we  maintain  workers’  compensation  insurance  to  cover  us  for  costs  and  expenses  we  may  incur  due  to  injuries  to  our
employees resulting from the use of hazardous materials or other work-related injuries, this insurance may not provide adequate coverage
against potential liabilities. In addition, we may incur substantial costs in order to comply with current or future environmental, health and
safety  laws  and  regulations.  These  current  or  future  laws  and  regulations  may  impair  our  research,  development  or  production  efforts.
Failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions.

We may not be successful in our efforts to identify or discover additional product candidates.

The  success  of  our  business  depends  primarily  upon  our  ability  to  identify  and  develop  product  candidates. Although  our  existing
product candidates are currently in clinical development, our research programs may fail to identify other potential product candidates for
clinical development for a number of reasons. Our research methodology may be unsuccessful in identifying potential product candidates
or  our  potential  product  candidates  may  be  shown  to  have  harmful  side  effects  or  may  have  other  characteristics  that  may  make  the
products unmarketable or unlikely to receive marketing approval.

If any of these events occur, we may be forced to abandon our development efforts for a program or programs, which would have a
material  adverse  effect  on  our  business  and  could  potentially  cause  us  to  cease  operations.  Research  programs  to  identify  new  product
candidates require substantial technical, financial and human resources. We may focus our efforts and resources on potential programs or
product candidates that ultimately prove to be unsuccessful.

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

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

48

 
 
 
 
 
 
 
 
 
 
We incur significant increased costs as a result of operating as a public company, and our management devotes substantial time to new
compliance initiatives.

As a US public company, we have incurred and will continue to incur significant legal, accounting and other expenses that we did not
incur as a UK public company. In addition, the Sarbanes-Oxley Act, as well as rules subsequently implemented by the SEC, have imposed
various requirements on public companies. In July 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-
Frank Act, was enacted. There are significant corporate governance and executive compensation related provisions in the Dodd-Frank Act
that require the SEC to adopt additional rules and regulations in these areas such as “say on pay” and proxy access. Stockholder activism,
the current political environment and the current high level of government intervention and regulatory reform may lead to substantial new
regulations  and  disclosure  obligations,  which  may  lead  to  additional  compliance  costs  and  impact  the  manner  in  which  we  operate  our
business in ways we cannot currently anticipate. Our management and other personnel will need to devote a substantial amount of time to
these  compliance  initiatives.  Moreover,  these  rules  and  regulations  will  increase  our  legal  and  financial  compliance  costs  and  will  make
some activities more time-consuming and costly. For example, we expect these rules and regulations to make it more difficult and more
expensive for us to obtain director and officer liability insurance and we may be required to incur substantial costs to maintain our current
levels of such coverage.

Unfavorable global economic conditions could adversely affect our business, financial condition or results of operations.

Our results of operations could be adversely affected by general conditions in the global economy and in the global financial markets.
The  recent  global  financial  crisis  caused  extreme  volatility  and  disruptions  in  the  capital  and  credit  markets.  A  severe  or  prolonged
economic downturn, such as the recent global financial crisis, could result in a variety of risks to our business, including, weakened demand
for our product candidates and our ability to raise additional capital when needed on acceptable terms, if at all. This is particularly true in
Europe, which is undergoing a continued severe economic crisis. A weak or declining economy could also strain our suppliers, possibly
resulting  in  supply  disruption,  or  cause  our  customers  to  delay  making  payments  for  our  services. Any  of  the  foregoing  could  harm  our
business and we cannot anticipate all of the ways in which the current economic climate and financial market conditions could adversely
impact our business.

We or the third parties upon whom we depend may be adversely affected by earthquakes or other natural disasters and our business
continuity and disaster recovery plans may not adequately protect us from a serious disaster.

Earthquakes  or  other  natural  disasters  could  severely  disrupt  our  operations,  and  have  a  material  adverse  effect  on  our  business,
results of operations, financial condition and prospects. If a natural disaster, power outage or other event occurred that prevented us from
using all or a significant portion of our headquarters, that damaged critical infrastructure, such as the manufacturing facilities of our third-
party contract manufacturers, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for us to continue
our business for a substantial period of time. The disaster recovery and business continuity plans we have in place currently are limited and
are  unlikely  to  prove  adequate  in  the  event  of  a  serious  disaster  or  similar  event.  We  may  incur  substantial  expenses  as  a  result  of  the
limited nature of our disaster recovery and business continuity plans, which could have a material adverse effect on our business.

Risks related to ownership of our common stock

Because our common stock is quoted on the OTCQB, our liquidity and the price of our common stock are limited.

Our  common  stock  are  traded  on  the  OTCQB  quotation  system,  which  is  a  FINRA-sponsored  entity  and  operated  inter-dealer
automated quotation system for equity securities not included in a national exchange. Quotation of our securities on the OTCQB limits the
liquidity and price of our common stock more than if our common stock were quoted or listed on the NYSE or the NASDAQ, which are
national securities exchanges. Lack of liquidity will limit the price at which you may be able to sell our securities or your ability to sell our
common stock at all.

The market price of our common stock may be highly volatile, and you may not be able to resell your shares at or above the price at
which you purchase them.

Companies  trading  in  the  stock  market  in  general  have  experienced  extreme  price  and  volume  fluctuations  that  have  often  been
unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect the
market price of our common stock, regardless of our actual operating performance.

The market price of our common stock may be volatile. Our stock price could be subject to wide fluctuations in response to a variety

of factors, including the following:

· Adverse results or delays in pre-clinical or clinical studies;
·
· Any  delay  in  filing  an  IND  or  BLA  for  any  of  our  product  candidates  and  any  adverse  development  or  perceived  adverse

Inability to obtain additional funding;

·

development with respect to the FDA’s review of that IND or BLA;
Failure to develop successfully our product candidates;
Failure to maintain our existing strategic collaborations or enter into new collaborations;
Failure  by  us  or  our  licensors  and  strategic  collaboration  partners  to  prosecute,  maintain  or  enforce  our  intellectual  property
rights;
Changes in laws or regulations applicable to future products;
Inability to obtain adequate product supply for our product candidates or the inability to do so at acceptable prices;

·
·
· Adverse regulatory decisions;

·
·
·
· Announcements  of  significant  acquisitions,  strategic  partnerships,  joint  ventures  or  capital  commitments  by  us,  our  strategic

Introduction of new products, services or technologies by our competitors;
Failure to meet or exceed financial projections we may provide to the public;
Failure to meet or exceed the financial projections of the investment community;
The perception of the pharmaceutical industry by the public, legislatures, regulators and the investment community;

collaboration partner or our competitors;

· Disputes  or  other  developments  relating  to  proprietary  rights,  including  patents,  litigation  matters  and  our  ability  to  obtain

patent protection for our technologies;

· Additions or departures of key scientific or management personnel;
Significant lawsuits, including patent or stockholder litigation;
·
Changes in the market valuations of similar companies;
·
Sales of our common stock by us or our stockholders in the future; and
·

Because our shares may be subject to the penny stock rules, it may be more difficult to sell our shares.

The SEC has adopted rules that regulate broker-dealer practices in connection with transactions in penny stocks. Penny stocks are
generally  equity  securities  with  a  price  of  less  than  $5.00  (other  than  securities  registered  on  certain  national  securities  exchanges  or
authorized  for  quotation  on  certain  automated  quotation  systems,  provided  that  current  price  and  volume  information  with  respect  to
transactions in such securities is provided by the exchange or system). The OTC Markets does not meet such requirements and for so long
as  the  price  of  our  common  stock  is  less  than  $5.00,  our  common  stock  will  be  deemed  penny  stocks.  The  penny  stock  rules  require  a
broker-dealer,  prior  to  a  transaction  in  a  penny  stock  not  otherwise  exempt  from  those  rules,  to  deliver  a  standardized  risk  disclosure
document containing specified information. In addition, the penny stock rules require that prior to effecting any transaction in a penny stock
not  otherwise  exempt  from  those  rules,  a  broker-dealer  must  make  a  special  written  determination  that  the  penny  stock  is  a  suitable
investment  for  the  purchaser  and  receive  (i)  the  purchaser’s  written  acknowledgment  of  the  receipt  of  a  risk  disclosure  statement;  (ii)  a
written  agreement  to  transactions  involving  penny  stocks;  and  (iii)  a  signed  and  dated  copy  of  a  written  suitability  statement.  These
disclosure  requirements  may  have  the  effect  of  reducing  the  trading  activity  in  the  secondary  market  for  our  securities,  and  therefore
security holders may have difficulty selling their shares.

Our principal stockholders and management own a significant percentage of our stock and will be able to exert significant control over
matters subject to stockholder approval.

Our  executive  officers,  directors,  and  their  affiliates  and  other  principal  stockholders  beneficially  own  approximately  60%  of  our
outstanding  common  stock.  Therefore,  these  stockholders  will  have  the  ability  to  influence  us  through  their  ownership  positions.  These
stockholders may be able to determine all matters requiring stockholder approval. For example, these stockholders, acting together, may be
able  to  control  elections  of  directors,  amendments  of  our  organizational  documents,  or  approval  of  any  merger,  sale  of  assets,  or  other
major corporate transaction. This may prevent or discourage unsolicited acquisition proposals or offers for our common stock that you may
believe are in your best interest as one of our stockholders.

We are an “emerging growth company,” and we cannot be certain if the reduced reporting requirements applicable to emerging growth
companies will make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. For as long
as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are
applicable  to  other  public  companies  that  are  not  emerging  growth  companies,  including  not  being  required  to  comply  with  the  auditor
attestation  requirements  of  Section  404  of  the  Sarbanes-Oxley Act  of  2002,  or  the  Sarbanes-Oxley Act,  reduced  disclosure  obligations
regarding  executive  compensation  in  our  periodic  reports  and  proxy  statements  and  exemptions  from  the  requirements  of  holding  a
nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

We could be an emerging growth company for up to approximately five years, although circumstances could cause us to lose that
status earlier, including if the market value of our common stock held by non-affiliates exceeds $700.0 million as of any June 30 before that
time or if we have total annual gross revenue of $1.0 billion or more during any fiscal year before that time, in which cases we would no
longer be an emerging growth company as of the following December 31 or, if we issue more than $1.0 billion in non-convertible debt
during any three-year period before that time, we would cease to be an emerging growth company immediately. Even after we no longer
qualify as an emerging growth company, we may still qualify as a “smaller reporting company” which would allow us to take advantage of
many  of  the  same  exemptions  from  disclosure  requirements,  including  not  being  required  to  comply  with  the  auditor  attestation
requirements  of  Section  404  of  the  Sarbanes-Oxley  Act  and  reduced  disclosure  obligations  regarding  executive  compensation  in  our
periodic reports and proxy statements. We cannot predict if investors will find our common stock less attractive because we may rely on
these  exemptions.  If  some  investors  find  our  common  stock  less  attractive  as  a  result,  there  may  be  a  less  active  trading  market  for  our
common stock and our stock price may be more volatile. If the requirement for internal control over financial reporting attestation were to
become applicable, then it could be determined that further steps may be considered necessary, at additional cost to the Company, in order
for our internal control environment to be deemed effective.

Under the JOBS Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as
those standards apply to private companies. In the preparation of our accounting reports, we have generally taken the position not to avail
ourselves  of  this  exemption  from  new  or  revised  accounting  standards  and,  therefore,  have  continued  to  be  subject  to  the  same  new  or
revised accounting standards as other public companies that are not emerging growth companies.

Actual  or  potential  sales  of  our  common  stock  by  our  employees,  including  our  executive  officers,  pursuant  to  pre-arranged  stock
trading plans could cause our stock price to fall or prevent it from increasing for numerous reasons, and actual or potential sales by
such persons could be viewed negatively by other investors.

In accordance with the guidelines specified under Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, and our policies
regarding  stock  transactions,  our  employees,  including  executive  officers,  may  adopt  stock  trading  plans  pursuant  to  which  they  have
arranged to sell shares of our common stock from time to time in the future. Generally, sales under such plans by our executive officers and
directors require public filings. Actual or potential sales of our common stock by such persons could cause the price of our common stock
to  fall  or  prevent  it  from  increasing  for  numerous  reasons.  For  example,  a  substantial  number  of  shares  of  our  common  stock  becoming
available (or being perceived to become available) for sale in the public market could cause the market price of our common stock to fall or
prevent it from increasing. Also, actual or potential sales by such persons could be viewed negatively by other investors.

Future  sales  and  issuances  of  our  common  stock  or  rights  to  purchase  common  stock  could  result  in  additional  dilution  of  the
percentage ownership of our stockholders and could cause our stock price to fall.

Additional capital will be needed in the future to continue our planned operations. To the extent we raise additional capital by issuing
equity securities, our stockholders may experience substantial dilution. We may sell common stock, convertible securities or other equity
securities  in  one  or  more  transactions  at  prices  and  in  a  manner  we  determine  from  time  to  time.  If  we  sell  common  stock,  convertible
securities or other equity securities in more than one transaction, investors may be materially diluted by subsequent sales. These sales may
also result in material dilution to our existing stockholders, and new investors could gain rights superior to our existing stockholders.

52

 
 
 
 
 
 
 
 
We could be subject to securities class action litigation.

In the past, securities class action litigation has often been brought against a company following a decline in the market price of its
securities. This risk is especially relevant for us because pharmaceutical companies have experienced significant stock price volatility in
recent years. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and resources, which
could harm our business.

We do not intend to pay dividends on our common stock so any returns will be limited to the value of our stock.

We have never declared or paid any cash dividends on our common stock. We currently anticipate that we will retain future earnings
for  the  development,  operation  and  expansion  of  our  business  and  do  not  anticipate  declaring  or  paying  any  cash  dividends  for  the
foreseeable future. Any return to stockholders will therefore be limited to the appreciation of their stock.

ITEM 1B – UNRESOLVED STAFF COMMENTS

None.

ITEM 2 – PROPERTIES

The  Company  occupies  a  facility  consisting  of  approximately  4,000  square  feet  in  the  Ledgemont  Center  in  Lexington,
Massachusetts.  The  premises  are  divided  into  approximately  50%  laboratory  and  50%  office  space  and  are  leased  by  the  Company’s
subsidiary, Xenetic Bioscience, Incorporated. The lease provides for an initial term of 61 months which commenced in January 2014 with
an extension option of one additional five-year term. We believe that this space is adequate for the Company’s current needs and that, if
additional space is required, it can be obtained at commercially reasonable terms either within the Ledgemont Center or nearby.

The  Company’s  subsidiaries,  Xenetic  UK  and  Lipoxen  Technologies  Limited  (“Lipoxen”),  jointly  occupied  approximately  1,200
square feet of general office space in London in the UK until March 20, 2015, when the lease was terminated pursuant to the terms of the
contract.

ITEM 3 – LEGAL PROCEEDINGS

We are not currently subject to any material legal proceedings, nor, to our knowledge, is any material legal proceeding threatened
against us. From time to time, we may be a party to certain legal proceedings, incidental to the normal course of our business. While the
outcome of these legal proceedings cannot be predicted with certainty, we do not expect that these proceedings will have a material effect
upon our financial condition or results of operations.

ITEM  5  –  MARKET  FOR  REGISTRANT’S  COMMON  EQUITY,  RELATED  STOCKHOLDER  MATTERS  AND  ISSUER
PURCHASES OF EQUITY SECURITIES

Our common stock is quoted under the symbol “XBIO” on the OTCQB operated by the Financial Industry Regulatory Authority, Inc.
(“FINRA”) and the OTCQB operated by the OTC Markets Group, Inc. Few market makers continue to participate in the OTCQB system
because of high fees charged by FINRA. Consequently, market makers that once quoted our shares on the OTCQB system may no longer
be  posting  a  quotation  for  our  shares. As  of  the  date  of  this  report,  however,  our  shares  are  quoted  by  several  market  makers  on  the
OTCQB. The criteria for listing on either the OTCQB are similar and include that we remain current in our SEC reporting. Our reporting is
presently current, and since inception, we have filed our SEC reports on time.

Only a limited market exists for our securities. There is no assurance that a regular trading market will develop, or if developed, that it

will be sustained. Therefore, a shareholder may be unable to resell his securities in our company.

The following table sets forth the range of high and low prices for our common stock for each of the periods indicated as reported by
the  OTCQB.  These  quotations  reflect  inter-dealer  prices,  without  retail  mark-up,  mark-down  or  commission  and  may  not  necessarily
represent actual transactions.

Penny Stock

The SEC has adopted rules that regulate broker-dealer practices in connection with transactions in penny stocks. Penny stocks are
generally equity securities with a market price of less than $5.00, other than securities registered on certain national securities exchanges or
quoted on the NASDAQ system, provided that the current price and volume information with respect to transactions in such securities is
provided  by  the  exchange  or  system.  The  penny  stock  rules  require  a  broker-dealer,  prior  to  a  transaction  in  a  penny  stock,  to  deliver  a
standardized risk disclosure document prepared by the SEC, that: (a) contains a description of the nature and level of risk in the market for
penny stocks in both public offerings and secondary trading; (b) contains a description of the broker’s or dealer’s duties to the customer and
of the rights and remedies available to the customer with respect to a violation of such duties or other requirements of the securities laws;
(c) contains a brief, clear, narrative description of a dealer market, including bid and ask prices for penny stocks and the significance of the
spread between the bid and ask price; (d) contains a toll-free telephone number for inquiries on disciplinary actions; (e) defines significant
terms in the disclosure document or in the conduct of trading in penny stocks; and (f) contains such other information and is in such form,
including language, type size and format, as the SEC shall require by rule or regulation.

The broker-dealer also must provide, prior to effecting any transaction in a penny stock, the customer with (a) bid and offer quotations
for the penny stock; (b) the compensation of the broker-dealer and its salesperson in the transaction; and (c) the number of shares to which
such bid and ask prices apply, or other comparable information relating to the depth and liquidity of the market for such stock; and (d) a
monthly account statement showing the market value of each penny stock held in the customer’s account.

In  addition,  the  penny  stock  rules  require  that  prior  to  a  transaction  in  a  penny  stock  not  otherwise  exempt  from  those  rules,  the
broker-dealer  must  make  a  special  written  determination  that  the  penny  stock  is  a  suitable  investment  for  the  purchaser  and  receive  the
purchaser’s written acknowledgment of the receipt of a risk disclosure statement, a written agreement as to transactions involving penny
stocks, and a signed and dated copy of a written suitability statement.

These disclosure requirements may have the effect of reducing the trading activity for  our  common  stock.  Therefore,  stockholders

may have difficulty selling our securities.

Holders of Record

As of April 10, 2015 there were 438 holders of common stock of the Company of record.

Dividends

There  are  no  restrictions  in  our  articles  of  incorporation  or  bylaws  that  prevent  us  from  declaring  dividends.  The  Nevada  Revised

Statutes, however, do prohibit us from declaring dividends where after giving effect to the distribution of the dividend:

· We would not be able to pay our debts as they become due in the usual course of business; or
· Our total assets would be less than the sum of our total liabilities plus the amount that would be needed to satisfy the rights of

shareholders who have preferential rights superior to those receiving the distribution.

56

 
 
 
 
 
 
 
 
 
 
 
 
 
 
The Company has never previously declared or paid any cash dividends on its common stock. We currently intend to retain earnings
and profits, if any, to support our business strategy and do not intend to pay any cash dividends within the foreseeable future. Any future
determination to pay cash dividends will be at the sole discretion of the Company’s Board of Directors and will depend upon the financial
condition of the Company, its operating results, capital requirements, general business conditions and any other factors that the Board of
Directors deems relevant.

ITEM 6 – SELECTED FINANCIAL DATA

We are not required to provide the information required by this Item because we are a smaller reporting company.

ITEM  7  –  MANAGEMENT’S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND  RESULTS  OF
OPERATIONS

BUSINESS OVERVIEW

As discussed under Recent Developments in Item 1, above, in this Annual Report filed on Form 10-K, the Company is now carrying
on  the  business  of  Xenetic  UK  as  its  sole  line  of  business.  Xenetic  UK,  and  now  therefore,  the  Company,  is  a  clinical  stage
biopharmaceutical company that is focused on the development of certain drug candidates for use in humans that incorporate the use of its
patented and proprietary platform technologies that we believe will enable the creation of novel and next generation drug therapies.

The Company is currently in various stages of development with respect to its three core patented and proprietary technologies, these

being, PolyXen® (for biologics), OncoHist™ (as a broad spectrum oncology therapy), and ImuXen® (for vaccines).

58

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The Company’s three core technologies are summarized as follows:

PolyXen®

OncoHist™

ImuXen®

An enabling technology that utilizes Polysialic Acid (“PSA”), a biopolymer, consisting of a chain of sialic acids which is a
natural constituent of the human body. PSA is designed to extend the half-life in circulation in the human body for a variety
of existing drug molecules and, thereby, to create potentially superior next generation drug candidates.
A novel therapeutic platform that utilizes the properties of the human histone H1.3 (“H1.3”) for the development of drug
candidates  for  the  treatment  of  a  broad  range  of  cancer  indications.  OncoHist™,  unlike  many  competing  oncology
therapies, is based on a molecule occurring naturally in the human body, in the cell nucleus, and is therefore expected to be
less toxic and immunogenetic than other oncology therapies.
A  novel  liposomal  co-entrapment  encapsulation  technology  designed  to  create  new  vaccines  and  improve  the  use  and
efficacy  of  certain  existing  vaccines  for  use  in  the  human  body.  The  technology  is  based  on  the  co-entrapment  of  the
nominated antigen(s) in a liposomal vesicle, a design that is intended to maximize both cell and immune system mediated
responses.

All  of  the  Company’s  current  drug  candidates  are  in  the  development  stage  and  none  has  yet  received  regulatory  approval  for

marketing in the US by the FDA or by any other applicable agencies in other countries.

Critical Accounting Estimates

The preparation of our financial statements in conformity with US GAAP requires management to make estimates, judgments and
assumptions  that  affect  the  reported  amounts  of  assets  and  liabilities  at  the  date  of  the  financial  statements  and  the  reported  amount  of
expenses during the reporting period. On an ongoing basis, we evaluate our estimates that are based on historical experience and on various
assumptions  that  we  believe  to  be  reasonable  under  the  circumstances.  The  result  of  these  evaluations  forms  the  basis  for  making
judgments about the carrying values of assets and liabilities and the reported amount of expenses that are not readily apparent from other
sources. Because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and
estimates, and such differences could be material.

Management believes that the following accounting estimates are the most critical to aid in fully understanding and evaluating our
reported financial results, and they require management’s most difficult subjective or complex judgments, resulting from the need to make
estimates about the effect of matters that are inherently uncertain. The following narrative describes these critical accounting estimates, the
judgments and assumptions and the effect if actual results differ from these assumptions.

Revenue Recognition

We  derive  our  revenue  from  our  license  and  collaboration  arrangements  with  pharmaceutical  and  biotechnology  partners,  some  of
which  include  royalty  agreements  based  on  potential  net  sales  of  approved  commercial  pharmaceutical  products.  Revenue  from  our
collaborative partners are generally paid directly by the partners and are recognized on the accrual basis when all the following criteria are
met: (i) persuasive evidence of an arrangement exists, (ii) delivery (or passage of title) has occurred or services have been rendered, (iii) the
seller's price to the buyer is fixed or determinable, and (iv) collectability is reasonably assured.

59

 
 
 
 
 
 
 
 
 
 
 
The  terms  of  our  license  agreements  include  delivery  of  an  IP  license  to  a  collaboration  partner.  We  may  be  compensated  under
license arrangements through a combination of non-refundable upfront receipts, development and regulatory objective receipts and royalty
receipts  on  future  product  sales  by  partners.  We  make  our  best  estimate  of  the  period  over  which  we  expect  to  fulfil  our  performance
obligations,  which  may  include  technology  transfer  assistance,  research  activities,  clinical  development  activities,  and  manufacturing
activities  from  development  through  the  commercialization  of  the  product.  Given  the  uncertainties  of  these  collaboration  arrangements,
significant judgment is required to determine the duration of the performance period.

Non-refundable  upfront  license  fees  received,  whereby  our  continued  performance  or  future  obligations  are  considered
inconsequential  or  perfunctory  to  the  relevant  licensed  technology,  are  recognized  as  revenue  upon  delivery  of  the  technology  in
accordance  with  US  GAAP.  This  determination  requires  significant  judgment  to  assess  the  nature  of  any  continuing  obligations.
Reimbursements  for  research  and  development  services  completed  by  us  related  to  the  collaboration  agreements  are  recognized  in
operations as revenue on a gross basis.

We expect to receive royalty receipts in the future as products are sold. We expect to recognize royalty revenue in the period of sale,
based on the underlying contract terms, provided that the reported sales are reliably measurable and we have no remaining performance
obligations, assuming all other revenue recognition criteria are met.

Our license and collaboration agreements with certain collaboration partners could also provide for future receipts to us based solely
upon the performance of the respective collaboration partner in consideration of milestone extensions or upon the achievement of specified
sales  volumes  of  approved  drugs.  For  such  receipts,  we  expect  to  recognize  the  receipts  as  revenue  when  earned  under  the  applicable
contract terms on a performance basis or ratably over the term of the agreement. These receipts may also be recognized as revenue when
our continued performance or future obligations are considered inconsequential or perfunctory.

Share-Based Compensation

Share-based compensation includes grants of options to employees and non-employees to purchase shares of common stock, grants of
Joint Share Ownership Plan (“JSOP”) awards to employees, as well as agreements to issue common stock in exchange for services provided
by non-employees. Currently, we utilize one option plan, the Xenetic Biosciences, Inc. Equity Incentive Plan pursuant to which we may
grant options to purchase shares of common stock to employees and non-employees. Prior to the Acquisition, the Company had two option
plans, the Lipoxen plc Unapproved Share Option Plan and the Xenetic Biosciences plc 2007 Share Option Scheme. Both of these plans
were  converted  subsequent  to  year  end  to  reflect  the  new  shares  of  common  stock  issued  related  to  the  Acquisition.  As  part  of  the
conversion,  option  holders  under  both  plans  have  the  right  to  subscribe  for  a  number  of  shares  of  common  stock  in  exchange  for  the
cancellation and surrender by the option holder in a manner similar to which the shareholders prior to the Acquisition were given the right
to acquire shares of common stock in the new company according to the terms of the Acquisition.

60

 
 
 
 
 
 
 
 
We measure share-based compensation in accordance with Financial Accounting Standards Board Accounting Standards Codification
(“ASC”) Topic 718, Compensation – Stock Compensation. Stock option compensation expenses are based on the estimated fair value of the
underlying  option  calculated  using  the  Black-Scholes  option  pricing  model,  which  requires  the  input  of  subjective  assumptions  and
judgments, including estimating share price volatility and expected term of the awards. Our shares do not have a sufficient trading history
for us to adequately assess the fair value of the stock option grants. Therefore, for all share-based payments, we determine the expected
volatility based on a weighted-average of the historical volatility of a peer group of comparable publicly traded companies with product
candidates in similar stages of development to our product candidates in conjunction with our historical volatility. We intend to consistently
apply this methodology of using a peer group of comparable companies until sufficient historical information regarding the volatility of our
own share price becomes available. For employee stock options issued in 2014 that qualify as “plain vanilla” stock options in accordance
with Staff Accounting Bulletin No. 110 (“SAB 110”) issued by the SEC, the expected term is estimated using the simplified method, as
defined  in  SAB  110.  The  Company  has  a  limited  history  of  stock  option  exercises,  which  does  not  provide  a  reasonable  basis  for  the
Company  to  estimate  the  expected  term  of  employee  stock  options.  For  all  other  employee  stock  options,  we  estimate  the  expected  life
using  judgment  based  on  the  anticipated  research  and  development  milestones  of  the  Company’s  clinical  projects  and  behavior  of  the
Company’s employees. The expected life of non-employee options is the contractual life of the option. The assumptions used in calculating
the fair value of the stock option grants represent our best estimates and involve inherent uncertainties and the application of our judgment.
As  a  result,  if  factors  change  and  we  use  different  assumptions,  share-based  compensation  expense  could  be  materially  different  in  the
future.

For employee options that vest based solely on service conditions, the fair value measurement date is generally on the date of grant
and the related compensation expense, less expense for expected forfeitures, is recognized on a straight-line basis over the requisite vesting
period of the awards. For non-employee options, the fair value measurement date is the earlier of the date the performance of services is
complete  or  the  date  the  performance  commitment  has  been  reached.  We  generally  determine  that  the  fair  value  of  the  stock  options  is
more  reliably  measurable  than  the  fair  value  of  the  services  received.  Compensation  expense  related  to  stock  options  granted  to  non-
employees that vest based solely on service conditions is subject to re-measurement at each reporting period until the options vest and is
recognized on a straight-line basis over the estimated vesting period of the awards.

We estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those
estimates.  During  2014  and  2013,  we  applied  a  forfeiture  rate  of  0%  as  we  have  not  historically  experienced  forfeitures.  During  2013,
options  to  purchase  approximately  two  million  shares  of  common  stock  were  forfeited  by  a  management  executive  as  a  result  of  his
unanticipated short period of employment. However, we concluded this situation is an independent event and we do not expect this type of
forfeiture to reoccur in the future. Upon exercise, stock options are redeemed for newly issued shares of common stock.

The fair value of common stock awards issued in exchange for services provided by non-employees is generally determined by using
the fair value of the services provided, as this provides the most reliable measure of the fair value of the awards. Share-based compensation
expense is recognized as services are rendered on a straight-line basis. The assumptions used in calculating the fair value of the common
stock  awards  represent  our  best  estimates  and  involve  inherent  uncertainties  and  the  application  of  our  judgment. As  a  result,  if  factors
change  and  we  use  different  assumptions,  share-based  compensation  expense  related  to  the  common  stock  awards  could  be  materially
different in the future.

Under the JSOP, shares of the Company are jointly purchased at fair market value by the participating executives and the trustees of
the JSOP trust, with shares held in the JSOP trust. For US GAAP purposes the awards are valued as employee options.  The  JSOP  trust
holds the shares of the JSOP until such time as the JSOP shares are vested and the participating executives exercise their rights under the
JSOP. The JSOP trust is granted an interest bearing loan by the Company in order to fund the purchase of its interest in the JSOP shares.
The loan held by the trust is eliminated on consolidation in the financial statements of the Company. The Company funded portion of the
share purchase price is deemed to be held in treasury until such time as they are transferred to the employee and is recorded as a reduction
in equity.

The exercise price of the JSOP “option” is deemed to be the market value of the shares at the date of issue. The awards vest based on
certain market conditions, which require each tranche of shares to meet specific market share price hurdles, or change in control conditions,
as defined by the plan. Under the JSOP and subject to the vesting of the participants’ interest, participating executives will, when the JSOP
shares are sold, be entitled to a share of the proceeds of sale equal to the growth in market value of the JSOP shares versus the exercise
price, less simple interest on the original share purchase price, net of executives’ cash contribution at inception, as agreed for each grant
(the “Carry Charge”). The balance of the proceeds will remain to the benefit of the JSOP trust and be applied to the repayment of the loan
originally made by the Company to the JSOP trust. Any funds remaining in the JSOP trust after settlement of the loan and any expenses of
the JSOP trust are for the benefit of the Company.

We  measure  the  fair  value  of  JSOP  awards  using  Monte  Carlo  simulations,  which  requires  estimates  based  on  the  Company’s
judgment,  as  well  as  other  assumptions.  These  estimates  include  the  expected  term  of  each  tranche  of  the  JSOP  awards,  which  the
Company  determines  to  be  the  initial  life  of  the  awards,  and  expected  volatility,  which  is  based  on  a  weighted  average  of  the  historical
volatility  of  a  peer  group  of  comparable  publicly  traded  companies  with  product  candidates  in  similar  stages  of  development  to  the
Company’s product candidates in conjunction with the historical volatility of Xenetic Biosciences plc’s shares when traded on the UK AIM
market. The Company has applied an expected dividend yield of 0% as the Company has not historically declared a dividend and does not
anticipate declaring a dividend during the expected life of the awards. The risk-free rate is based upon the US Treasury yield curve in effect
at  the  time  of  grant,  with  a  term  that  approximates  the  expected  life  of  the  awards.  The  compensation  expense  is  recorded  over  the
expected life of the option, regardless of whether the awards vest. Having established the full value of the JSOP awards using the Monte
Carlo simulation outlined above, a deduction is made in respect of the anticipated Carry Charge in order that the expense recorded in the
financial  statements  only  represents  the  participating  executives’  net  interest  in  the  awards.  The  assumptions  used  in  calculating  the  fair
value of the JSOP awards represent our best estimates and involve inherent uncertainties and the application of our judgment. As a result, if
factors  change  and  we  use  different  assumptions,  share-based  compensation  expense  related  to  the  JSOP  awards  could  be  materially
different in the future.

On  exercise  of  the  JSOP  awards  by  the  executives  the  Carry  Charge  due  to  the  Company  will  be  recognized  as  additional  paid-in

capital, arising from the sale of treasury stock.

Warrants

In  connection  with  certain  financing  and  collaboration  arrangements,  we  issue  warrants  to  purchase  shares  of  the  Company’s
common  stock  to  our  collaborative  partners.  Outstanding  warrants  are  standalone  instruments  that  are  not  puttable  or  mandatorily
redeemable  by  the  holder  and  are  classified  as  equity  awards.  We  measure  the  fair  value  of  the  awards  using  the  Black-Scholes  option
pricing model, which requires the input of subjective assumptions and judgments, including estimating the expected term of the awards and
the share price volatility, at each reporting period until the measurement date is reached. The expected term is deemed to be the contractual
life  of  the  warrant  and  we  determine  the  expected  volatility  based  on  a  weighted-average  of  the  historical  volatility  of  a  peer  group  of
comparable publicly traded companies with product candidates in similar stages of development to our product candidates in conjunction
with our historical volatility.

All other warrants are recorded at fair value as compensation expense on a straight-line basis over the requisite service period or at
the date of issuance, if there is not a service period or if service has already been rendered. For warrants that contain vesting triggers based
on the achievement of certain objectives, the Company applies judgment to estimate the probability and timing of the achievement of those
objectives.  These  estimates  involve  inherent  uncertainties,  and  as  a  result,  if  the  probability  or  timing  of  the  achievement  of  those
objectives change, expense related warrants could be materially different in the future.

Warrants issued to collaboration partners in conjunction with the issuance of common stock are recorded at fair value as a reduction

in additional paid-in capital of the common stock issued.

Business Combinations

We have a history of engaging in acquisition transactions that require us to evaluate whether the transaction meets the criteria for a
business combination and, in some cases, whether it meets the definition of a reverse merger. For those acquisitions that meet the criteria
for a reverse merger, we evaluate the entities involved to distinguish the appropriate accounting acquirer and acquiree according to ASC
Topic 805, Business Combinations (“ASC 805”). If the transaction does not meet the business combination requirements, the transaction is
accounted for as a recapitalization and no goodwill or intangible assets are recognized. If the acquisition meets the definition of a business
combination, we allocate the purchase price, including any contingent consideration, to the assets acquired and the liabilities assumed at
their estimated fair values as of the date of the acquisition with any excess of the purchase price paid over the estimated fair value of net
assets acquired recorded as goodwill. The fair value of the assets acquired and liabilities assumed is typically determined by using either
estimates of replacement costs or discounted cash flow valuation methods.

When determining the fair value of tangible assets acquired, we estimate the cost to replace the asset with a new asset taking into
consideration such factors as age, condition and the economic useful life of the asset. When determining the fair value of intangible assets
acquired, we use judgment to estimate the applicable discount rate, growth rates and the timing and amount of future cash flows. The fair
value of assets acquired and liabilities assumed is typically determined using the assistance of an independent third party specialist. The
assumptions  used  in  calculating  the  fair  value  of  tangible  and  intangible  assets  represent  our  best  estimates  and  involve  inherent
uncertainties and the application of our judgment. As a result, if factors change and we use different assumptions, valuations of tangible and
intangible  assets  and  the  resulting  goodwill  balance  related  to  the  business  combination  could  be  materially  different  or  impaired  in  the
future.

During January 2014, we completed the Acquisition that we determined to be a reverse merger business combination. In accordance
with ASC 805, we allocated the purchase price consideration to the assets acquired and liabilities assumed at their estimated fair values as
of  the  date  of  acquisition.  Our  determination  that  the Acquisition  meets  the  criteria  for  a  business  combination  was  based  on  our  best
knowledge of the facts and circumstances surrounding the transaction, and requires the application of our judgment.

Goodwill and Indefinite-lived Intangible Assets

Goodwill

Goodwill  is  not  amortized  but  is  reviewed  for  impairment  annually  as  of  October  1,  or  when  events  or  changes  in  the  business
environment indicate that all, or a portion, of the carrying value of the reporting unit may no longer be recoverable. Under this method, we
compare the fair value of our reporting unit to its carrying value. If the fair value is less than the carrying amount, a more detailed analysis
is performed to determine if goodwill is impaired. An impairment loss, if any, is measured as the excess of the carrying value of goodwill
over the fair value of goodwill. We also have the option to first assess qualitative factors to determine whether the existence of events or
circumstances leads us to determine that it is more likely than not (that is, a likelihood of more than 50%) that goodwill is impaired. If we
choose to first assess qualitative factors and it is determined that it is not more likely than not goodwill is impaired, we are not required to
take further action to test for impairment. We also have the option to bypass the qualitative assessment and perform only the quantitative
impairment test, which we may choose to do in some periods but not in others. As the option to perform the qualitative assessment is not a
permanent election, we reassess this option during each annual impairment review.

We determine our reporting unit by identifying the components of our operating segment with similar economic characteristics based
on quantitative and qualitative factors that have discrete financial information available. We determined that we have one reporting unit as
of  October  1,  2014  and  2013,  the  dates  of  our  annual  impairment  reviews.  Based  on  our  annual  impairment  reviews,  we  used  the
quantitative method and determined no adjustment to the carrying value of goodwill would be necessary as the fair value of our reporting
unit significantly exceeded its respective carrying value as of October 1, 2014 and 2013, respectively. If the fair value of our reporting unit
were to be reduced by one-half, the fair value would still significantly exceed the carrying value of the reporting unit at October 1, 2014.
There can be no assurance that future events will not result in an impairment of goodwill.

63

 
  
 
 
 
 
 
 
 
 
Indefinite-lived Intangible Assets

Our indefinite-lived intangible assets consist of acquired IPR&D. IPR&D intangible assets are considered indefinite-lived intangible
assets until completion or abandonment of the associated research and development efforts. IPR&D is not amortized but is reviewed for
impairment annually as of October 1, or when events or changes in the business environment indicate the carrying value may be impaired.
If  the  fair  value  of  the  intangible  asset  is  less  than  the  carrying  amount,  we  perform  a  quantitative  test  to  determine  the  fair  value.  The
impairment loss, if any, is measured as the excess of the carrying value of the intangible asset over its fair value. We also have the option to
first assess qualitative factors to determine whether the existence of events or circumstances leads us to determine that it is more likely than
not (that is, a likelihood of more than 50%)  that  our  indefinite-lived  intangible  asset  is  impaired.  If  we  choose  to  first  assess  qualitative
factors and it is determined that it is not more likely than not our indefinite-lived intangible asset is impaired, we are not required to take
further  action  to  test  for  impairment.  We  also  have  the  option  to  bypass  the  qualitative  assessment  and  perform  only  the  quantitative
impairment test, which we may choose to do in some periods but not in others. As the option to perform the qualitative assessment is not a
permanent election, we reassess this option during each annual impairment review. During 2014 and 2013, we used the quantitative method
and determined the fair value of the indefinite-lived intangible asset exceeded its carrying value as of October 1, 2014 and 2013.

Significant judgments are inherent in the calculation of fair value. With the assistance of an independent third party, we calculated
the fair value of our IPR&D by using the Multi-Period Excess Earnings Method (the “MPEEM”) which is a form of the income approach.
Under the MPEEM, the fair value of an intangible asset is equal to the present value of the asset’s incremental after-tax cash flows (excess
earnings) remaining after deducting the market rates of return on the estimated value of contributory assets (contributory charge) over its
remaining useful life. This method requires us to make long-term projections of the amount and timing of income and expenses related to
development and commercialization of the acquired intangible asset and assumptions regarding the rate of return on contributory assets, the
weighted average cost of capital and the discount rate for estimated future after-tax cash flows. Specifically, this method took into account
our estimates of future incremental milestone payments that may be achieved upon completion of clinical trial stages, regulatory approval
and sales goals upon commercialization, as well as our expected royalty income based on sales upon commercialization. Projected expenses
are based on our forecasted spend required to complete the development of our IPR&D, which will require the Company to raise further
capital to fund the development. Our projections are estimates subject to change based on several factors including the results of clinical
trials  and  delays  in  regulatory  approval.  The  discount  rate  used  is  commensurate  with  the  uncertainties  associated  with  the  economic
estimates described above and reflects the stage of development, the time and resources needed to complete the development of the product
and the risks of advancement through regulatory approval processes.

Key assumptions utilized in the fair valuation of our indefinite-lived intangible asset OncoHist™ are as follows:

· Discount rate – 47.5%
· Weighted average cost of capital – 24.6%
·
·

Estimated aggregate milestone receipts – approximately £350 million
Royalty rates – 10% of net sales

While  we  believe  reasonable  estimates  and  appropriate  assumptions  were  utilized  to  calculate  the  fair  value  of  OncoHist™,  it  is
possible a material change could occur. Use of different estimates and judgments could yield materially different results in our analysis and
could result in materially different asset values or expense.

There can be no assurance that we will be able to successfully develop and complete the acquired IPR&D program and profitably
commercialize the underlying product candidates before our competitors develop and commercialize similar products, or at all. Moreover,
if  the  acquired  IPR&D  program  fails  or  is  abandoned  during  development,  then  we  may  not  realize  the  value  we  have  estimated  and
recorded in our financial statements on the acquisition date, and we may also not recover the research and development investment made
since  the  acquisition  date  to  further  develop  that  program.  If  such  circumstances  were  to  occur,  our  future  operating  results  could  be
materially adversely impacted.

64

 
 
 
 
 
 
 
 
 
We did not record an impairment charge as a result of our goodwill or indefinite-lived intangible asset impairment tests in 2014 or
2013.  We  will  continue  to  closely  monitor  the  performance  of  our  indefinite-lived  intangible  asset  and  reporting  unit.  If  the  business
experiences adverse changes in our key assumptions and judgments, we will perform an interim goodwill and/or indefinite-lived intangible
asset impairment analysis. There can be no assurance that future events will not result in an impairment of our goodwill or indefinite-lived
intangible asset. As a result of the going concern uncertainty discussed under Liquidity and Capital Resources below, the recoverability and
classification of the Company’s intangible assets and goodwill could be adversely affected.

Revenue for the year ended December 31, 2014 decreased 100% to $0 from $1,000,000 for the year ended December 31, 2013. The
revenue  for  2013  is  comprised  of  a  single  transaction  consisting  of  an  upfront  non-refundable  license  fee  in  the  amount  of  $1  million
received from Baxter. We did not record any upfront license fee revenue from Baxter during 2014.

Cost of Revenue

Cost of revenue was $0 for the years ended December 31, 2014 and 2013. The only revenue recorded during 2013 consisted of an

upfront non-refundable license fee that had no direct costs associated with it for the period.

The increase in R&D expenses in the US during 2014 was primarily due to costs associated with IND enabling preclinical work for
the OncoHist™ program that began in 2014. The UK expenses are attributed primarily to the ongoing ErepoXen® human clinical trials
being conducted in Australia.

During 2013 we began the process of transitioning our R&D laboratory facilities to the US, leading to a reduction in non-program
specific related costs incurred in the UK, with a corresponding increase in such costs incurred in the US. The sharp increase in US-based
R&D expenses in 2014 were expected as the new Lexington facility increased its operational activity.

Research and Development by Category of Expense

Salaries and Wages

Salaries  and  wages  decreased  by  approximately  $463,000  or  38.8%  to  $729,082  for  the  year  ended  December  31,  2014  from
$1,191,806  for  the  prior  year.  The  decrease  is  due  to  the  planned  overall  reduction  in  the  number  of  scientific  personnel  in  2014  as
compared to 2013. The closing of the UK lab facility at the end of 2013 resulted in the layoffs of five UK-based scientific personnel, which
were only partially offset by the hiring of two new scientists in the US. The Company continued its planned increase in the use of contract
research organizations and external consultants during 2014.

Share-based Compensation

Share-based compensation expenses increased approximately $81,000 or 132.3% to $141,634 for the year ended December 31, 2014
from  $60,980  for  the  prior  year.  The  fluctuation  is  from  expected  changes  resulting  from  the  normal  expensing  of  the  fair  value  of
outstanding stock options, primarily driven by the increase resulting from the required re-measurement of outstanding non-employee stock
options at the balance sheet date.

Outside Services and CRO Costs

The significant increase in outside services and CRO costs of approximately $3.63 million, or 245.5% for the year ended December
31, 2014 is primarily due to the planned IND enabling preclinical work conducted in connection with the OncoHist™ program. The costs
of conducting the ongoing ErepoXen® human clinical trials in Australia were relatively static, with costs of approximately $1.12 million
and $1.23 in 2014 and 2013, respectively.

Rents

The decline in rent expense of approximately $160,000, or 67.2%, to $78,076 for the year ended December 31, 2014 from $237,888
for the prior year is due to the planned closing of the UK research facility at the end of 2013. This decrease was partially offset by the cost
of  operating  the  Company’s  new  research  facility  in  the  US,  which  began  operations  in  January  2014.  The  Company  believes  the  new
research facility in the US, which has lower operating costs than the former research facility in the UK, will meet its needs through at least
2016.

Lab Consumables

The slight decrease of approximately $7,500 in lab consumables expense is due to normal fluctuations in the amount of those supplies

required for in-house research activities.

Other

Other expenses increased approximately $161,000, or 202.7%, to $240,834 for the year ended December 31, 2014 from $79,565 for
the prior year. The increase in other expense results from the net aggregate change of all miscellaneous costs, including an approximately
$56,000  increase  in  computer  equipment  and  software  related  costs,  approximately  $37,000  increase  in  maintenance  and  utilities  costs,
approximately $32,000 increase in depreciation expense and a $30,000 increase in recruiting costs.

Clinical Development Strategy

The Company’s strategy has been to co-ordinate its R&D effort through its new US Lexington facility. This has entailed the closing
of  laboratory  facilities  in  the  UK.  The  Company  has  a  clear  strategy  of  becoming  a  specialty  drug  developer. Accordingly  it  plans  to
increase both its current US-based internal level of effort alongside the initiation of new programs with the assistance of external entities,
such as Contract Research and Contract Manufacturing Organizations. There will, therefore, be a need for the Company to access additional
capital resources to fund this strategy and the rate at which the strategy can be implemented will be entirely dependent upon access to such
funding.

General and Administrative

General and administrative expenses increased by approximately $136,000, or 2.1%, to $6,600,870 for the year ended December 31,
2014 from $6,464,908 for the prior year. Although the total level of general and administrative costs did not change significantly, legal and
accounting  professional  service  costs  increased  approximately  $674,000  and  investor  relations,  regulatory  fees  and  insurance  costs
increased approximately $493,000 due to the first year of normal administrative costs of conducting business as a US public company in
2014, which did not exist prior to the Acquisition. These increases were offset by an approximately $1.15 million decrease in contractor and
consultant service costs, the bulk of which related to the Acquisition, which were mostly incurred in 2013.

Salaries  and  wages,  share-based  compensation  and  other  employee  benefit  costs  increased  by  approximately  $38,000.  All  other
general and administrative expenses resulted in a net increase of approximately $60,000 for the year ended December 31, 2014 over the
comparable period in 2013.

Impairment of In-Process Research and Development

We did not record any impairment charges related to acquired IPR&D during 2014 or 2013.

Loss on Disposal of Subsidiaries

The loss on disposal of subsidiaries is related to one transaction, the Hive Out Agreement, during the year ended December 31, 2014.

There was not a disposal of a subsidiary during the year ended December 31, 2013.

Other Income (Expense)

Other  expense  increased  approximately  $261,000,  or  394.0%  to  $326,916  for  the  year  ended  December  31,  2014  from  $66,177  in
2013. This increase is primarily related to losses resulting from the high fluctuation of foreign currency exchange rates during 2014 due to
the steady weakening of the British pound against the US dollar throughout 2014.

Interest Income

Interest income decreased by $15,896, or 46% to $18,959 for the year ended December 31, 2014 from $34,855 in 2013. The decrease
is proportional to the decrease in average cash balances held by the Company during the period from January 1, 2013 to December 31, 2014
and is not due to any change in investments.

Interest Expense

Interest expense decreased by $4,074, or 644%, to $4,706 for the year ended December 31, 2014 from $632 in 2013. The increase is
primarily due to a financing with respect to the Company’s contribution to the landlord’s leasehold improvements related to the Company’s
office and laboratory space lease which commenced on January 1, 2014.

Liquidity and Capital Resources

At December 31, 2014 and 2013 we had approximately $78,000 and $1.7 million of working capital (current assets minus current
liabilities),  respectively. At  December  31,  2014  we  had  approximately  $2.5  million  in  cash  and  $2.7  million  in  total  current  liabilities,
which  includes  $395,000  due  to  an  affiliate  of  the  Company,  which  the  Company  does  not  expect  to  repay  prior  to  a  registered  equity
offering by the Company, and balances of approximately $635,000 currently disputed by the Company. At December 31, 2013 we had cash
and current liabilities of $4.8 million and $3.6 million respectively. Our working capital has been reduced in 2014 due to our net loss of
$14.3 million that includes $12.3 million net cash used in operating activities comprised of approximately $4.1 million applied to external
research and development and clinical program costs, approximately $3.0 million applied to salaries and wages, approximately $1.0 million
in general and administrative consultants and contractors and approximately $3.7 million in legal and other professional fees, partially offset
by  financing  cash  inflows  from  the  sale  of  $10  million  of  equity  to  Baxter  in  2014.  The  $4.1  million  applied  to  external  research  and
development and clinical program costs primarily related to our ErepoXen® and OncoHist™ drug candidates. The $3.7 million legal and
other  professional  fees  cash  outflows  in  2014  includes  $1.9  million  of  costs  that  were  incurred  during  2013  but  paid  in  2014.  Based  on
current cash on hand at the date of filing this Annual Report, we estimate we have sufficient funds to continue operations through the end of
April 2015.

We have historically relied principally upon equity financing to fund our operations. Since 2005 we have raised approximately $47
million in equity financing, including $10 million from the sale of shares to Baxter in January 2014. From 2005 to date the Company also
generated approximately $10 million from fee-for-service and license milestone revenues; however, the Company is not currently engaged
in  any  fee-for  service  activities;  consequently  we  expect  that  the  majority  of  any  new  funding  raised  in  the  foreseeable  future  will  arise
from a combination of:

(a) In the immediate short term, by the raising of bridge financing through such means as may be open to us;
(b) Within  the  current  fiscal  year,  by  the  issuance  of  new  capital  through  the  form  of  an  S-1  Registration  Statement  or  private

investment in public equity financing;

(c) Within 12-18 months by the out-licensing of one of more product candidates or technologies;
(d) In the longer term, from the receipt of “milestone payments” vested in the important Baxter product license for their PSA-Factor

VIII product candidate

In relation to these possible sources of new capital/cash:

i. We are presently working with multiple parties investigating the raising of additional working capital through either a convertible

debt or convertible preferred stock instrument, this by way of a bridge financing.

   More  specifically,  we  are  currently  finalizing  terms  associated  with  entering  into  a  Securities  Purchase Agreement  whereby  the
Company will issue up to an aggregate of $3 million of Senior Secured Collateralized Convertible Promissory Notes (the “Notes”),
with  a  third  party,  which  should  generate  cash  proceeds  of  approximately  $2.8  million,  net  of  costs.  We  estimate  the  sale  of  the
Notes will provide enough working capital to fund our business through September 2015. Arrangements are being put in place for
management and others to provide loan capital independent of the planned bridge financing noted above sufficient to extend the cash
“runway” of the Company to at least May 31, 2015; such funding may also be made available alongside the proposed bridge.

ii. Management  is  currently  taking  steps  to  raise  additional  working  capital  in  the  form  of  a  planned  underwritten  registered  public
offering of debt or equity, or a combination of debt and equity. The Company has engaged an investment banker to advise and assist
with this planned underwritten public offering, which it hopes to complete by September 30, 2015. The Company has presented its
business  plan  to  potential  investors,  and,  based  upon  the  progress  of  continuing  discussions  with  them,  is  optimistic  it  will  raise
sufficient working capital to meet its obligations through April 30, 2016. The Company needs to raise additional net new capital of a
minimum of $9 million prior to September 2015 in order to fund its planned operations through April 30, 2016.

iii. We have also now initiated the process necessary for the out-licensing of our ErepoXen® product candidate, currently in the latter

stage of its Phase II(a) clinical trial in Australia.

iv. While  we  have  no  direct  control  over  the  timing  of  the  matter,  we  have  been  guided  that  Baxter  hopes  to  enter  Phase  I  human
clinical  trials  for  its  PSA-Factor  VIII  product  candidate  within  12-18  months.  However,  no  related  milestone  payments  will  arise
until completion of the relevant clinical advances which cannot be precisely determined at this time.

There can be no assurance that we will be successful in our efforts to raise additional working capital by way of a bridge financing, or
on any future equity transaction or, even if we are successful, that we will be able to do so on commercially reasonable terms. Further, due
to the uncertainties inherent in the clinical research process and unknown future market conditions, there can be no assurance that either our
ErepoXen® candidate will lead to any future fees or that Baxter itself will be successful in initiating human clinical trials in the estimated
timeframe  or  that  the  underlying  product  will  meet  the  clinical  milestones  necessary  to  trigger  any  payment  to  the  Company  under  the
terms of our license agreement with them.

While the financial statements have been prepared on a going concern basis, if we do not successfully conclude the planned bridge
financing during April 2015 and the planned follow on public offering by September 2015, there is no assurance that we would be able to
continue  planned  operations  and  these  condition  raise  substantial  doubt  about  our  ability  to  continue  as  a  going  concern.    Under  such
circumstances, we would have to further reduce the planned scale of, or possibly suspend, all of our pre-clinical development initiatives and
clinical trials delivered by external service providers.  In addition, we would have to reduce general and administrative expenses, and delay
or cease the purchase of clinical research services until we are able to obtain additional financing. The recoverability and classification of
the Company’s intangible assets and goodwill could also be adversely affected.

Cash Flows Used in Operating Activities

Cash flows used in operating activities for the year ended December 31, 2014 totaled approximately $12.3 million. The $12.3 million
includes  net  operating  cash  uses  of  approximately  $7.00  million  in  consulting,  legal  and  other  professional  service  fees,  approximately
$3.01 million in salaries and wages, including scientific staff, and approximately $1.80 million in program-specific clinical development
costs.

Cash flows used in operating activities for the year ended December 31, 2013 totaled approximately $6.05 million, which includes
net operating cash uses of approximately $7.05 million, partially offset by $1 million in payments received from Baxter. The $7.05 million
includes  approximately  $2.42  million  in  salaries  and  wages,  including  scientific  staff,  and  $1.45  million  in  program-specific  clinical
development costs.

Cash Flows from Investing Activities

Cash flows used in investing activities for the year ended December 31, 2014 included approximately $58,000 from the purchase of
assets  consisting  of  office  furniture  and  fixtures  and  laboratory  equipment,  partially  offset  by  approximately  $5,500  derived  from  the
disposition of certain property and equipment during the year.

Cash flows used in investing activities for the year ended December 31, 2013 included approximately $79,000 from the purchase of
assets consisting of office furniture and fixtures and laboratory equipment. During 2013, we restricted $66,000 in cash as a guarantee of the
Company’s obligations under non-cancelable lease obligations.

Cash Flow from Financing Activities

For  the  year  ended  December  31,  2014  we  received  $10  million  in  proceeds  in  exchange  for  the  issuance  of  approximately  10.7
million shares of common stock to Baxter and we received approximately $102,000 in proceeds in connection with the exercise of stock
options by the CEO of the company. The proceeds were applied toward our working capital needs during the year. During the year, we
repaid approximately $286,000 on our loan to an affiliate of the Company.

For the year ended December 31, 2013 we had no significant sources or uses of funds from financing activities.

Off Balance Sheet Arrangements

The  Company  has  no  off  balance  sheet  financing  arrangements.  The  Company  has  two  facility  lease  obligations  and  written

employment agreements with three key employees.

Recent Accounting Pronouncements

In August  2014,  the  Financial Accounting  Standard  Board  (FASB)  issued ASU  2014-15,  Presentation  of  Financial  Statements  –
Going  Concern  (Subtopic  205-40)  (“ASU  2014-15”). ASU  2014-15  defines  management’s  responsibility  to  evaluate  whether  there  is
substantial doubt about an organization’s ability to continue as a going concern and provides guidance on the related footnote disclosures.
This  guidance  is  effective  for  annual  reporting  periods  beginning  after  December  15,  2016,  and  interim  periods  within  annual  periods
beginning after December 15, 2016. Early application is permitted. We are currently evaluating the impact of this new standard.

In May 2014, the FASB issued ASU 2014-09,  Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). ASU 2014-09
supersedes the revenue recognition requirements in ASC Topic 605,  Revenue Recognition, and most industry-specific guidance. The core
principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an
amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. This guidance is
effective  for  annual  reporting  periods  beginning  after  December  15,  2016,  including  interim  periods  within  that  reporting  period,  under
either  full  or  modified  retrospective  approach.  Early  application  is  not  permitted.  We  are  currently  evaluating  the  impact  of  this  new
standard on its revenue recognition policy.

We have considered other recent accounting pronouncements and determined that they are either not applicable to our business or

that no material effect is expected on the consolidated financial statements as a result of future adoption.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of Xenetic Biosciences, Inc.

We have audited the accompanying consolidated balance sheets of Xenetic Biosciences, Inc. (the “Company”) as of December 31,
2014 and 2013, and the related consolidated statements of comprehensive loss, changes in stockholders’ equity, and cash flows for each of
the two years in the period ended December 31, 2014. Our audits also include the financial statement schedule. These financial statements
and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements
based on our audits.

We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those
standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable  assurance  about  whether  the  financial  statements  are  free  of
material  misstatement.  We  were  not  engaged  to  perform  an  audit  of  the  Company’s  internal  control  over  financial  reporting.  Our  audits
included  consideration  of  internal  control  over  financial  reporting  as  a  basis  for  designing  audit  procedures  that  are  appropriate  in  the
circumstances,  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the  Company’s  internal  control  over  financial
reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of
Xenetic Biosciences, Inc. at December 31, 2014 and 2013, and the consolidated results of its operations and its cash flows for each of the
two years in the period ended December 31, 2014, in conformity with US generally accepted accounting principles. Also, in our opinion,
the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly, in all
material respects, the information set forth therein.

The  accompanying  consolidated  financial  statements  have  been  prepared  assuming  that  the  Company  will  continue  as  a  going
concern. As disclosed in Note 1 to the Financial Statements, the Company’s recurring losses from operations and its requirement to raise
funds  to  continue  operations  beyond April  2015,  raise  substantial  doubt  about  its  ability  to  continue  as  a  going  concern.  Management’s
plans in regard to these matters are also described in Note 1. The 2014 consolidated financial statements do not include any adjustments to
reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may
result from the outcome of this uncertainty.

XENETIC BIOSCIENCES, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.

The Company

Background

Xenetic Biosciences, Inc. (the “Company”), incorporated in the state of Nevada and based in Lexington, Massachusetts, is a clinical
stage  biopharmaceutical  company  that  is  focused  on  the  discovery,  development  and  planned  commercialization  of  a  new  generation  of
human drug therapies for the treatment of a variety of conditions including anemia, refractory Acute Myeloid Leukemia, Cystic Fibrosis
and certain cancers based upon its proprietary and patented drug delivery platform systems and drug development collaborations with major
third party pharmaceutical companies around the world.

The  Company’s  drug  delivery  platform  systems  include  PolyXen®  for  creating  next  generation  biologic  drugs  by  extending  the
efficacy,  safety  and  half-life  of  existing  biologic  drugs,  OncoHist™  for  the  development  of  novel  oncology  drug  therapies  focused  on
orphan indications in humans and ImuXen® for the development of vaccines that can simultaneously deliver multiple active pharmaceutical
ingredients.  The  Company  is  also  developing  a  broad  pipeline  of  drug  candidates  for  next  generation  biologics  and  novel  oncology
therapeutics in a number of orphan disease indications.

With  the  Company’s  relocation  to  the  United  States  from  the  United  Kingdom,  the  Company,  having  historically  been  a  research
organization, is now focused on employing United States based drug development expertise leveraging off its 140 issued patents and 90
patent  applications  to  develop  a  proprietary  drug  pipeline  of  next  generation  products.   All  the  rights  over  the  Company’s  patents  and
licenses are controlled in the United Kingdom.

Going Concern

At December 31, 2014 and 2013 the Company had approximately $78,000 and $1.7 million of working capital (current assets minus
current  liabilities),  respectively. At  December  31,  2014,  the  Company  had  approximately  $2.5  million  in  cash  and  $2.7  million  in  total
current  liabilities,  which  includes  $395,000  due  to  an  affiliate  of  the  Company,  which  the  Company  does  not  expect  to  repay  prior  to  a
registered equity offering by the Company, and balances of approximately $635,000 currently disputed by the Company. At December 31,
2013, the Company had cash and current liabilities of $4.8 million and $3.6 million, respectively. The Company’s working capital has been
reduced  in  2014  due  to  its  net  loss  of  $14.3  million  that  includes  $12.3  million  net  cash  used  in  operating  activities  comprised  of
approximately $4.1 million applied to external research and development and clinical program costs, approximately $3.0 million applied to
salaries and wages, approximately $1.0 million in general and administrative consultants and contractors and approximately $3.7 million in
legal and other professional fees, partially offset by financing cash inflows from the sale of $10 million of equity to Baxter in 2014. The
$4.1 million applied to external research and development and clinical program costs primarily related to the Company’s ErepoXen® and
OncoHist™ drug candidates. The $3.7 million legal and other professional fees cash outflows in 2014 includes $1.9 million of costs that
were incurred during 2013 but paid in 2014. Based on current cash on hand at the date of filing this Annual Report, the Company estimates
it has sufficient funds to continue operations through the end of April 2015.

The  Company  has  historically  relied  principally  upon  equity  financing  to  fund  its  operations.  Since  2005  the  Company  has  raised
approximately $47 million in equity financing, including $10 million from the sale of shares to Baxter in January 2014. From 2005 to date
the Company also generated approximately $10 million from fee-for-service and license milestone revenues; however, the Company is not
currently engaged in any fee-for service activities; consequently the Company expects that the majority of any new funding raised in the
foreseeable future will arise from a combination of:

(a) In the immediate short term, by the raising of bridge financing through such means as may be open to the Company;
(b) Within  the  current  fiscal  year,  by  the  issuance  of  new  capital  through  the  form  of  an  S-1  Registration  Statement  or  private

investment in public equity financing;

(c) Within 12-18 months by the out-licensing of one of more product candidates or technologies;
(d) In the longer term, from the receipt of “milestone payments” vested in the important Baxter product license for their PSA-Factor

VIII product candidate.

F-6

 
 
 
 
 
 
 
 
 
 
 
In relation to these possible sources of new capital/cash:

i. The  Company  is  presently  working  with  multiple  parties  investigating  the  raising  of  additional  working  capital  through  either  a

convertible debt or convertible preferred stock instrument, this by way of a bridge financing.

   More specifically, the Company is currently finalizing terms associated with entering into a Securities Purchase Agreement whereby
the  Company  will  issue  up  to  an  aggregate  of  $3  million  of  Senior  Secured  Collateralized  Convertible  Promissory  Notes  (the
“Notes”),  with  a  third  party,  which  should  generate  cash  proceeds  of  approximately  $2.8  million,  net  of  costs.  The  Company
estimates the sale of the Notes will provide enough working capital to fund its business through September 2015. Arrangements are
being  put  in  place  for  management  and  others  to  provide  loan  capital  independent  of  the  planned  bridge  financing  noted  above
sufficient to extend the cash “runway” of the Company to at least May 31, 2015; such funding may also be made available alongside
the proposed bridge.

ii. Management  is  currently  taking  steps  to  raise  additional  working  capital  in  the  form  of  a  planned  underwritten  registered  public
offering of debt or equity, or a combination of debt and equity. The Company has engaged an investment banker to advise and assist
with this planned underwritten public offering, which it hopes to complete by September 30, 2015. The Company has presented its
business  plan  to  potential  investors,  and,  based  upon  the  progress  of  continuing  discussions  with  them,  is  optimistic  it  will  raise
sufficient working capital to meet its obligations through April 30, 2016. The Company needs to raise additional net new capital of a
minimum of $9 million prior to September 2015 in order to fund its planned operations through April 30, 2016.

iii. The Company has also now initiated the process necessary for the out-licensing of our ErepoXen® product candidate, currently in

the latter stage of its Phase II(a) clinical trial in Australia.

iv. While the Company has no direct control over the timing of the matter, the Company has been guided that Baxter hopes to enter
Phase  I  human  clinical  trials  for  its  PSA-Factor  VIII  product  candidate  within  12-18  months.  However,  no  related  milestone
payments will arise until completion of the relevant clinical advances which cannot be precisely determined at this time.

There can be no assurance that the Company will be successful in our efforts to raise additional working capital by way of a bridge
financing,  or  on  any  future  equity  transaction  or,  even  if  the  Company  is  successful,  that  the  Company  will  be  able  to  do  so  on
commercially  reasonable  terms.  Further,  due  to  the  uncertainties  inherent  in  the  clinical  research  process  and  unknown  future  market
conditions, there can be no assurance that either the Company’s ErepoXen® candidate will lead to any future fees or that Baxter itself will
be successful in initiating human clinical trials in the estimated timeframe or that the underlying product will meet the clinical milestones
necessary to trigger any payment to the Company under the terms of its license agreement with them.

While  the  financial  statements  have  been  prepared  on  a  going  concern  basis,  if  the  Company  does  not  successfully  conclude  the
planned bridge financing during April 2015 and the planned follow on public offering by September 2015, there is no assurance that the
Company would be able to continue planned operations and these conditions raise substantial doubt about its ability to continue as a going
concern.  Under such circumstances, the Company would have to further reduce the planned scale of, or possibly suspend, all of its pre-
clinical development initiatives and clinical trials delivered by external service providers.  In addition, the Company would have to reduce
general  and  administrative  expenses,  and  delay  or  cease  the  purchase  of  clinical  research  services  until  the  Company  is  able  to  obtain
additional  financing.  The  recoverability  and  classification  of  the  Company’s  intangible  assets  and  goodwill  could  also  be  adversely
affected.

Recent Significant Transaction

On January 23, 2014, the Company consummated a reverse merger (the “Acquisition”) pursuant to a written plan of reorganization,
in  which  the  Company  merged  with  Xenetic  Biosciences  (UK)  Limited  (formerly  Xenetic  Biosciences  plc)  (“Xenetic  UK”),  a  company
incorporated  in  England  and  Wales  under  the  Companies Act  of  1985,  such  that  Xenetic  UK  became  a  wholly  owned  subsidiary  of  the
Company. Upon completion of the Acquisition, the Company acquired all issued and outstanding shares of capital stock of Xenetic UK. As
a result, 132,545,504 shares of the Company’s common stock were newly issued and, immediately following the Acquisition, there were
136,045,504 shares of common stock issued and outstanding. At that time, because former Xenetic UK shareholders owned approximately
97%  of  the  combined  company  on  a  fully  diluted  basis  and  all  members  of  the  combined  company’s  executive  management  were  from
Xenetic  UK,  Xenetic  UK  was  deemed  to  be  the  acquiring  company  for  accounting  purposes  and  the  transaction  was  accounted  for  as  a
reverse acquisition in accordance with accounting principles generally accepted in the United States (“US GAAP”).

Prior to the Acquisition, the Company changed its name from General Sales and Leasing, Inc. to Xenetic Biosciences, Inc. As used in
these consolidated financial statements, unless otherwise indicated, all references herein to “Xenetic”, the “Company”, “we” or “us” refer
to Xenetic Biosciences, Inc. and its wholly owned subsidiaries.

Summary of Significant Accounting Policies

Preparation of Financial Statements

These financial statements have been prepared on the assumption that the Company will be able to realize its assets and discharge its
liabilities in the normal course of business. This assumption is presently in question and contingent upon the Company’s ability to raise
additional working capital. The financial statements do not include any adjustments relating to recoverability and classification of recorded
asset amounts or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going
concern.

Certain research and development and general and administrative expense classifications for the year ended December 31, 2013 on
the consolidated statement of comprehensive loss have been reclassified to conform to the current period presentation. In addition, certain
property and equipment classifications as of December 31, 2013 have been reclassified to conform to the current period presentation.

Principles of Consolidation

The  financial  statements  of  the  Company  include  the  accounts  of  Xenetic  UK  and  its  wholly  owned  subsidiaries:  Lipoxen
Technologies Limited (“Lipoxen”), Xenetic Bioscience, Incorporated, and SymbioTec GmbH (“SymbioTec”). All material intercompany
balances and transactions have been eliminated on consolidation.

In  accordance  with  the  reverse  acquisition  guidance  in  Financial  Accounting  Standards  Board  (“FASB”)  Accounting  Standards
Codification  (“ASC”)  Topic  805  Business  Combinations  (“ASC  805”),  the  consolidated  financial  statements  for  the  year  ended
December 31, 2013 of the Company (the accounting acquiree) are a continuation of the financial statements of Xenetic UK (the accounting
acquirer),  adjusted  to  retroactively  change  Xenetic  UK’s  legal  capital  to  reflect  the  legal  capital  of  the  Company.  This  adjustment  was
calculated based upon the share exchange ratio of 56 new shares of Company common stock for every whole 175 shares of Xenetic UK
capital  stock  previously  issued  and  outstanding.  Comparative  information  preserved  in  these  consolidated  financial  statements  is  also
retroactively adjusted to reflect the legal capital of the Company. The legal capital at December 31, 2014 reflects the legal capital of the
Company after the Acquisition date and therefore requires no adjustment.

Use of Estimates

The preparation of the financial statements in accordance with US GAAP requires management to make estimates, judgments and
assumptions  that  affect  the  reported  amounts  of  assets  and  liabilities,  the  reported  amounts  of  revenue  and  expenses  in  the  financial
statements and disclosures in the accompanying notes. Actual results and outcomes may differ materially from management’s estimates,
judgments and assumptions.

Fair Value of Financial Instruments

ASC Topic 820 Fair Value Measurement defines fair value as the price that would be received to sell an asset or be paid to transfer a
liability  in  an  orderly  transaction  between  market  participants  at  the  measurement  date.  The  Company  applies  the  following  fair  value
hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon
the lowest level of input that is available and significant to the fair value measurement. Level 1 inputs are quoted prices in active markets
for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 utilizes quoted market
prices in markets that are not active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency.
Level 3 inputs are unobservable inputs for the asset or liability in which there is little, if any, market activity for the asset or liability at the
measurement date.

The Company’s cash and cash equivalents and restricted cash are measured at fair value on a recurring basis and classified as Level 1
in  the  fair  value  hierarchy  because  they  are  valued  using  quoted  prices  for  the  years  ended  December  31,  2014  and  2013.  The  carrying
amount of certain of the Company’s financial instruments approximate fair value due to their short maturities.

F-8

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Cash, Cash Equivalents and Investments

The  Company  considers  all  highly  liquid  investments  with  maturities  of  90  days  or  less  from  the  date  of  purchase  to  be  cash
equivalents. Investments with original maturities of greater than 90 days from the date of purchase but less than one year from the balance
sheet date are classified as short-term investments, while investments with maturities of one year or beyond from the balance sheet date are
classified as long-term investments. Management determines the appropriate classification of its cash equivalents and investment securities
at the time of purchase and re-evaluates such determination as of each balance sheet date.

Restricted Cash

As  of  December  31,  2014,  restricted  cash  represents  a  certificate  of  deposit  that  matures  annually,  and  secures  the  Company’s
outstanding letter of credit of $66,000 for the operating lease for new office and laboratory space in Lexington, Massachusetts. The letter of
credit is required to be maintained through the term of the lease, which expires in January 2019.

Concentration of Credit Risk

Financial  instruments  that  subject  the  Company  to  concentrations  of  credit  risk  include  cash  and  cash  equivalents.  The  Company
maintains cash and cash equivalents with various major financial institutions. The Company performs periodic evaluations of the relative
credit standing of these financial institutions and limits the amount of credit exposure with any one institution.

Property and Equipment

The  Company  records  property  and  equipment  at  cost  less  accumulated  depreciation.  Expenditures  for  major  renewals  and
improvements  which  extend  the  life  or  usefulness  of  the  asset  are  capitalized.  Items  of  an  ordinary  repair  or  maintenance  nature  are
charged directly to operating expense as incurred. The Company periodically reviews the estimated useful lives assigned to property and
equipment, and the Company changes its estimates to reflect the results of those reviews. During the first quarter of 2014, the Company
completed such a review and, as a result, decreased the estimated useful lives of laboratory and office and computer equipment from four
years to three years. Separately, the estimated useful lives of furniture and fixtures and leasehold improvements was increased from four
years to five years. The effect of this change in estimate for the year ended December 31, 2014 is not material to the Company’s financial
position or results of operations.

The Company calculates depreciation using the straight-line method over the estimated useful lives of the assets:

Asset Classification
Laboratory equipment
Office and computer equipment
Leasehold improvements
Furniture and fixtures

Estimated Useful Life

3 years
3 years
5 years or the remaining term of the lease, if shorter
5 years

The Company eliminates the cost of assets retired or otherwise disposed of, along with the corresponding accumulated depreciation,

from the related accounts, and the resulting gain or loss is reflected in the results of operations.

Indefinite-Lived Intangible Assets

Acquired  indefinite-lived  intangible  assets  consist  of  In-Process  Research  and  Development  (“IPR&D”)  related  to  the  Company’s
business combination with SymbioTec, which were recorded at fair value on the acquisition date. IPR&D intangible assets are considered
indefinite-lived  intangible  assets  until  completion  or  abandonment  of  the  associated  research  and  development  efforts.  Substantial
additional research and development may be required before the Company’s IPR&D reaches technological feasibility. Upon completion of
the IPR&D project, the IPR&D assets will be amortized over their estimated useful lives.

F-9

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In  accordance  with ASC  Topic  350  Intangibles  -  Goodwill  and  Other  (“ASC  350”),  the  Company  assesses  intangible  assets  with
indefinite  lives  for  impairment  at  least  annually  as  of  October  1,  or  when  events  or  changes  in  the  business  environment  indicate  the
carrying value may not be fully recoverable. The Company also has the option to first assess qualitative factors to determine whether the
existence of events or circumstances leads to the determination that it is more likely than not (that is, a likelihood of more than 50%) that
the acquired IPR&D is impaired. If the Company chooses to first assess the qualitative factors and it is determined that it is not more likely
than not acquired IPR&D is impaired, the Company is not required to take further action to test for impairment. The Company also has the
option to bypass the qualitative assessment and perform only the quantitative impairment test, which the Company may choose to perform
in some periods but not in others.

The determinations as to whether, and, if so, the extent to which, acquired IPR&D become impaired are highly judgmental and based
on significant assumptions regarding the probability of success and the timing of projected cash flows, projected future financial condition
and operating results, changes in the manner of the use and development of the acquired assets, the Company’s overall business strategy,
and regulatory, market and economic environment and trends. No impairment was recorded during the years ended December 31, 2014 or
2013.

Goodwill

Goodwill is comprised of the purchase price of business combinations in excess of the fair value assigned at acquisition to the net
tangible and identifiable intangible assets acquired. See Note 3, Acquisitions, for further information on the goodwill activity related to the
Acquisition and the subsequent disposal of subsidiaries. Goodwill is not amortized, but in accordance with ASC 350, the Company assesses
goodwill for impairment at least annually, or when events or changes in the business environment indicate the carrying value may not be
fully  recoverable.  The  Company  also  has  the  option  to  first  assess  qualitative  factors  to  determine  whether  the  existence  of  events  or
circumstances leads to the determination that it is more likely than not (that is, a likelihood of more than 50%) that goodwill is impaired. If
the  Company  chooses  to  first  assess  qualitative  factors  and  it  is  determined  that  it  is  not  more  likely  than  not  goodwill  is  impaired,  the
Company  is  not  required  to  take  further  action  to  test  for  impairment.  The  Company  also  has  the  option  to  bypass  the  qualitative
assessment and perform only the quantitative impairment test, which the Company may choose to do in some periods but not in others. The
Company performs its annual impairment review as of October 1.

In  addition,  the  Company  assesses  market  conditions,  industry  developments  and  internal  operations  to  determine  if  events  or
changes in the business environment indicate the carrying value of goodwill may not be fully recoverable. No impairment was recorded
during the years ended December 31, 2014 or 2013.

Impairment of Long-Lived Assets

In  accordance  with ASC  Topic  360  Property,  Plant  and  Equipment ,  the  Company  reviews  long-lived  assets  to  be  held  and  used,
including property and equipment, for impairment whenever events or changes in circumstances indicate that the carrying amount of the
assets or asset group may not be fully recoverable. No such impairments were recorded during the years ended December 31, 2014 or 2013.

Evaluation  of  recoverability  is  based  on  an  estimate  of  undiscounted  future  cash  flows  resulting  from  the  use  of  the  asset  or  asset
group and its eventual disposition. Impairment, if any, is calculated as the amount by which an asset’s carrying value exceeds its fair value,
typically using discounted cash flows to determine fair value.

Foreign Currency Translation

The  Company’s  reporting  currency  is  United  States  (“US”)  dollars.  During  the  years  ended  December  31,  2014  and  2013,  the
Company had operations in the United Kingdom (“UK”), US and Germany. The functional currencies of the operations in the UK, US and
Germany are their local currencies: British pounds sterling, US dollars and euros, respectively. Assets and liabilities of foreign operations
are translated to US dollars at the exchange rate in effect at the balance sheet date and revenue and expenses at the average exchange rate
for  the  period.  Gains  and  losses  from  the  translation  of  the  consolidated  financial  statements  of  foreign  subsidiaries  into  US  dollars  are
included in stockholders’ equity as a component of other comprehensive income. The Company does not record tax provisions or benefits
for the net changes in foreign currency translation adjustments, as the company intends to permanently reinvest undistributed earnings in its
foreign  subsidiaries.  Realized  and  unrealized  gains  and  losses  resulting  from  foreign  currency  transactions  arising  from  exchange  rate
fluctuations on balances denominated in currencies other than the functional currencies, are recognized in “Other (expense) income” in the
consolidated statements of comprehensive loss. Monetary assets and liabilities that are denominated in a currency other than the functional
currency are re-measured to the functional currency using the exchange rate at the balance sheet date and gains or losses are recorded in
“Other (expense) income” in the consolidated statements of comprehensive loss.

Revenue Recognition

The Company enters into supply, license and collaboration arrangements with pharmaceutical and biotechnology partners, some of
which include royalty agreements based on potential net sales of approved commercial pharmaceutical products. The Company recognizes
revenue in accordance with the authoritative guidance, ASC Topic 605,  Revenue Recognition. The Company recognizes revenue when all
of the following criteria are met: (i) persuasive evidence of an arrangement exists, (ii) delivery (or passage of title) has occurred or services
have been rendered, (iii) the seller’s price to the buyer is fixed or determinable, and (iv) collectability is reasonably assured.

The terms of the Company’s license agreements include delivery of an Intellectual Property (“IP”) license to a collaboration partner.
The Company may be compensated under license arrangements through a combination of non-refundable upfront payments, development
and  regulatory  objective  payments  and  royalty  payments  on  future  product  sales  by  partners.  Non-refundable  upfront  payments  and
development  and  regulatory  objective  payments  received  by  the  Company  in  license  and  collaboration  arrangements  that  include  future
obligations,  such  as  supply  obligations,  are  recognized  ratably  over  the  Company’s  expected  performance  period  under  each  respective
arrangement. The Company makes its best estimate of the period over which the Company expects to fulfil the Company’s performance
obligations,  which  may  include  technology  transfer  assistance,  research  activities,  clinical  development  activities,  and  manufacturing
activities  from  development  through  the  commercialization  of  the  product.  Given  the  uncertainties  of  these  collaboration  arrangements,
significant  judgment  is  required  to  determine  the  duration  of  the  performance  period.  Non-refundable  upfront  license  fees  received,
whereby continued performance or future obligations are considered inconsequential or perfunctory to the relevant licensed technology, are
recognized as revenue upon delivery of the technology.

The Company expects to recognize royalty revenue in the period of sale, based on the underlying contract terms, provided that the
reported sales are reliably measurable and the Company has no remaining performance obligations, assuming all other revenue recognition
criteria are met.

Reimbursements  for  research  and  development  services  completed  by  the  Company  related  to  the  collaboration  agreements  are

recognized in operations as revenue on a gross basis.

The Company’s license and collaboration agreements with certain collaboration partners could also provide for future payments to
the Company based solely upon the performance of the respective collaboration partner in consideration of deadline extensions or upon the
achievement of specified sales volumes of approved drugs. For such payments, the Company expects to recognize the payments as revenue
when earned under the applicable contract terms on a performance basis or ratably over the term of the agreement. These payments may
also  be  recognized  as  revenue  when  continued  performance  or  future  obligations  by  the  Company  are  considered  inconsequential  or
perfunctory.

Refer to Note 4, Significant Strategic Drug Development Collaborations, for discussion on arrangements with specific collaboration

partners.

Research and Development Expenses

Research  and  development  expenses  consist  of  expenses  incurred  in  performing  research  and  development  activities,  including
compensation and benefits, facilities expenses, overhead expenses, clinical trial and related clinical manufacturing expenses, fees paid to
Clinical Research Organizations and Clinical Manufacturing Organizations and other outside expenses. The Company expenses research
and development costs as incurred. The Company expenses upfront, non-refundable payments made for research and development services
as obligations are incurred. The value ascribed to intangible assets acquired but which have not met capitalization criteria is expensed as
research and development at the time of acquisition.

Share-Based Compensation

Stock options

The  Company  grants  share-based  payments  in  the  form  of  options  to  employees  and  non-employees,  Joint  Share  Ownership  Plan
(“JSOP”) awards to employees, as well as agreements to issue common stock in exchange for services provided by non-employees. The
Company measures share-based payments in accordance with ASC Topic 718, Compensation – Stock Compensation.

Stock option compensation expenses are based on the fair value of the underlying option calculated using the Black-Scholes option
pricing model. Determining the appropriate fair value model and related assumptions requires judgment, including estimating share price
volatility and expected terms of the awards. The expected volatility rates are estimated based on the actual volatility of the Company and of
comparable public companies over the expected term. The expected terms represent the time that options are expected to be outstanding.
The Company estimates forfeitures at the time of grant and revises those estimates in subsequent periods if actual forfeitures differ from
those  estimates.  The  Company  has  not  paid  dividends  and  does  not  anticipate  paying  cash  dividends  in  the  foreseeable  future  and,
accordingly,  uses  an  expected  dividend  yield  of  zero.  The  risk-free  interest  rate  is  based  on  the  rate  of  US  Treasury  securities  with
maturities consistent with the estimated expected term of the awards. Upon exercise, stock options are redeemed for newly issued shares of
common stock.

For employee options that vest based solely on service conditions, the fair value measurement date is generally on the date of grant
and the related compensation expense, less expense for expected forfeitures, is recognized on a straight-line basis over the requisite vesting
period of the awards. For non-employee options, the fair value measurement date is the earlier of the date the performance of services is
complete or the date the performance commitment has been reached. The Company generally determines that the fair value of the stock
options is more reliably measurable than the fair value of the services received. Compensation expense related to stock options granted to
non-employees that vest based solely on service conditions is subject to re-measurement at each reporting period until the options vest and
is recognized on a straight-line basis over the requisite vesting period of the awards.

Common stock awards

The Company grants common stock awards to non-employees in exchange for services provided. The Company generally measures
the fair value of these awards using the fair value of the services provided as it is a more reliable measure of the fair value of the awards.
The  fair  value  measurement  date  of  these  awards  is  generally  the  date  the  performance  of  services  is  complete.  The  fair  value  of  the
awards is recognized on a straight-line basis as services are rendered. The share-based compensation related to common stock awards for
the settlement of services provided by non-employees is recorded on the consolidated statement of comprehensive loss in the same manner
and charged to the same account as if such settlements had been made in cash.

Joint Share Ownership Plan awards

The Company measures the fair value of JSOP awards using Monte Carlo simulations based on the terms of the plan, which includes
vesting conditions based on the achievement of certain market conditions in the form of share price hurdles. Accordingly, the Company
recognizes  compensation  expense  related  to  its  JSOP  awards  using  a  graded  vesting  model.  Determination  of  the  appropriate  fair  value
model and related assumptions requires judgment, including estimating share price volatility and the expected term of the awards.

Warrants

In connection with certain financing and collaboration arrangements, the Company issues warrants to purchase shares of its common
stock to its collaborative partners. The outstanding warrants are standalone instruments that are not puttable or mandatorily redeemable by
the holder and are classified as equity awards. The Company measures the fair value of the awards using the Black-Scholes option pricing
model  as  of  the  measurement  date.  Warrants  issued  to  collaboration  partners  in  conjunction  with  the  issuance  of  common  stock  are
recorded at fair value as a reduction in additional paid-in capital of the common stock issued. All other warrants are recorded at fair value
as compensation expense over the requisite service period or at the date of issuance, if there is not a service period. Warrants granted in
connection with ongoing arrangements are more fully described in Note 9, Stockholders’ Equity.

Income Taxes

The Company accounts for income taxes using the liability method in accordance with ASC Topic 740,  Income Taxes.  Under  this
method, deferred tax assets and liabilities are determined based on temporary differences resulting from the different treatment of items for
tax and financial reporting purposes. 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 reverse. Additionally, the Company must assess the likelihood
that  deferred  tax  assets  will  be  recovered  as  deductions  from  future  taxable  income.  The  Company  evaluates  the  recoverability  of  its
deferred tax assets on a quarterly basis.

Basic and Diluted Net Loss per Share

The Company computes basic net loss per share by dividing net loss attributable to common stockholders by the weighted-average
number  of  shares  of  common  stock  outstanding  during  the  period.  The  Company  computes  diluted  net  loss  per  share  after  giving
consideration to the dilutive effect of stock options that are outstanding during the period, except where such non-participating securities
would  be  anti-dilutive.  The  Company’s  JSOP  awards,  prior  to  exercise,  are  considered  treasury  shares  by  the  Company  and  thus  do  not
impact the Company’s net loss per share calculation.

Basic and diluted net loss per share are the same for the years ended December 31, 2014 and 2013 as the Company was in a net loss
position. Potentially dilutive non-participating securities have not been included in the calculations of diluted net loss per share, as their
inclusion would be anti-dilutive.

Segment Information

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for
evaluation by the chief operating decision maker, who is the Company’s chief executive officer, in making decisions on how to allocate
resources and assess performance. The Company views its operations and manages its business in one operating segment.

Operating Leases

The  Company  leases  administrative  and  laboratory  facilities  under  operating  leases.  Lease  agreements  may  include  rent  holidays,
rent escalation clauses and tenant improvement allowances. The Company recognizes scheduled rent increases on a straight-line basis over
the lease term beginning with the date the Company takes possession of the leased space.

Business Combinations

The  Company  has  a  history  of  engaging  in  acquisition  transactions  that  require  the  Company  to  evaluate  whether  the  transaction
meets the criteria of a business combination and, in some cases, whether it meets the definition of a reverse merger. For those acquisitions
that meet the criteria for a reverse merger, the Company evaluates the entities involved to distinguish the appropriate accounting acquirer
and acquiree according to ASC 805. If the transaction does not meet the business combination requirements, the transaction is accounted
for  as  a  recapitalization  and  no  goodwill  or  intangible  assets  are  recognized.  If  the  acquisition  meets  the  definition  of  a  business
combination, the Company allocates the purchase price, including any contingent consideration, to the  assets  acquired  and  the  liabilities
assumed at their estimated fair values as of the date of the acquisition with any excess of the purchase price paid over the estimated fair
value of net assets acquired recorded as goodwill. The fair value of the assets acquired and liabilities assumed is typically determined by
using either estimates of replacement costs or discounted cash flow valuation methods.

When determining the fair value of tangible assets acquired, the Company estimates the cost to replace the asset with a new asset,
taking  into  consideration  such  factors  as  age,  condition  and  the  economic  useful  life  of  the  asset.  When  determining  the  fair  value  of
intangible assets acquired, the Company uses judgment to estimate the applicable discount rate, growth rates and the timing and amount of
future cash flows. The fair value of assets acquired and liabilities assumed is typically determined using the assistance of an independent
third party specialist.

Acquisition related costs are expensed in the period in which the costs are incurred and the services are received.

Recent Accounting Pronouncements

In August  2014,  the  Financial Accounting  Standard  Board  (FASB)  issued ASU  2014-15,  Presentation  of  Financial  Statements  –
Going  Concern  (Subtopic  205-40)  (“ASU  2014-15”). ASU  2014-15  defines  management’s  responsibility  to  evaluate  whether  there  is
substantial doubt about an organization’s ability to continue as a going concern and provides guidance on the related footnote disclosures.
This  guidance  is  effective  for  annual  reporting  periods  beginning  after  December  15,  2016,  and  interim  periods  within  annual  periods
beginning after December 15, 2016. Early application is permitted. The Company is currently evaluating the impact of this new standard.

In May 2014, the FASB issued ASU 2014-09,  Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). ASU 2014-09
supersedes the revenue recognition requirements in ASC Topic 605,  Revenue Recognition, and most industry-specific guidance. The core
principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an
amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. This guidance is
effective  for  annual  reporting  periods  beginning  after  December  15,  2016,  including  interim  periods  within  that  reporting  period,  under
either full or modified retrospective approach. Early application is not permitted. The Company is currently evaluating the impact of this
new standard on its revenue recognition policy.

The  Company  has  considered  other  recent  accounting  pronouncements  and  concluded  that  they  are  either  not  applicable  to  the

business, or that no material effect is expected on the consolidated financial statements as a result of future adoption.

Acquisitions

On January 23, 2014, the Company completed the Acquisition transaction with Xenetic UK which resulted in the Company acquiring
all  of  the  issued  and  outstanding  common  stock  of  Xenetic  UK.  The Acquisition  was  accounted  for  as  a  reverse  acquisition  under  the
acquisition  method  of  accounting  per ASC  805,  with  Xenetic  UK  treated  as  the  accounting  acquirer  and  the  Company  treated  as  the
“acquired”  company  for  financial  reporting  purposes.  This  was  determined  based  on  the  following  facts:  (i)  after  the  reverse  merger,
former  shareholders  of  Xenetic  UK  held  a  majority  of  the  voting  interest  of  the  combined  company;  (ii)  former  Board  of  Directors  of
Xenetic UK possess majority control of the Board of Directors of the combined company; and (iii) members of the management of Xenetic
UK  are  responsible  for  the  management  of  the  combined  company. As  such,  the  financial  statements  of  Xenetic  UK  are  treated  as  the
historical financial statements of the combined company.

The fair value of the consideration transferred in the reverse merger was $3.75 million. This was calculated as the number of shares
of common stock that Xenetic UK would have had to issue in order for the Company’s shareholders to hold the same equity interest in the
combined  entity  immediately  following  the  acquisition  (approximately  9.2%),  multiplied  by  the  estimated  fair  value  of  the  Company’s
common stock on the acquisition date (£0.06 per share). The estimated fair value of the Company’s common stock was based on the price
of  the  Company’s  stock  on  the  acquisition  date,  which  was  actively  traded  on  the Alternative  Investments  Market  of  the  London  Stock
Exchange  in  the  United  Kingdom.  In  addition,  Xenetic  UK  incurred  approximately  $3  million  of  transaction  costs  related  to  the  reverse
merger. The Company recognized approximately $0.5 million and $2.5 million of transaction costs related to the reverse merger in general
and  administrative  expenses  on  the  consolidated  statement  of  comprehensive  loss  during  the  years  ended  December  31,  2014  and  2013,
respectively.

As of December 31, 2014, the Company finalized the purchase accounting for the Acquisition. Management determined the purchase
price  allocations  based  on  estimates  of  the  fair  values  of  all  assets  acquired  and  liabilities  assumed.  The  Company  believe  that  such
information  provides  a  reasonable  basis  for  estimating  the  fair  values  of  assets  acquired  and  liabilities  assumed.  The  fair  values  of  the
acquired assets and liabilities assumed are as follows:

Cash
Accounts receivable
Prepaid expenses
Property, plant and equipment
Accounts payable
Accrued expenses
Long-term debt

Total identifiable net assets

Following the Acquisition, an Agreement of Conveyance, Transfer and Assignment of Subsidiaries and Assumption of Obligations
(the  “Hive  Out Agreement”)  was  executed,  whereupon  10,000,000  outstanding  shares  of  common  stock  held  by  Oxbridge  Technology
Partners  SA  (“Oxbridge”)  were  returned  to  the  Company  and  recorded  as  treasury  shares  and  were  subsequently  canceled.  In  exchange,
Oxbridge  acquired  all  issued  and  outstanding  shares  of  both  of  the  Company’s  former  operating  subsidiaries,  Shift  It  Media  Co.  and
General  Aircraft,  Inc.  (the  “Disposed  Subsidiaries”),  including  all  assets  and  liabilities  connected  with  the  businesses  transferred.  In
addition, the Company disposed of the associated goodwill. The Hive Out Agreement also required a payment to Oxbridge of $430,000,
which was paid by the Company shortly after the Acquisition.

The  Company  recorded  this  divestiture  as  a  separate  transaction  from  the Acquisition  that  results  in  the  disposal  of  two  of  the
Company’s subsidiaries. The Disposed Subsidiaries did not record any operations in the combined entity following the Acquisition before
they  were  disposed  and  these  financial  statements  do  not  reflect  the  historical  financial  statements  of  the  Disposed  Subsidiaries  as  they
were previously owned by the accounting acquiree. Accordingly, there are no balances to be recorded as discontinued operations on the
statement of comprehensive loss. As a result of the divestiture of the Disposed Subsidiaries, the Company recorded a loss on disposal of
subsidiaries of $1,069,675 during the year ended December 31, 2014.

Due  to  the  nature  of  the Acquisition  and  related  Hive  Out Agreement,  the  transaction  did  not  result  in  any  adjustments  with  a

continuing impact on the Company’s results of operations.

Significant Strategic Drug Development Collaborations

Baxter Healthcare SA and Baxter Healthcare Corporation

In August 2005, the Company entered into an exclusive research, development, license and supply agreement with Baxter Healthcare
SA (“Baxter SA”) and Baxter Healthcare Corporation (together referred to as “Baxter”) to develop products with an extended half-life of
certain proteins and molecules using the Company’s patent protected PolyXen ® technology whereby polysialic acid (“PSA” – a chain of
polysialic  acids)  is  conjugated  with  Baxter’s  proprietary  molecule(s)  to  create  a  new  generation  of  drugs  to  treat  the  failure  of  blood  to
coagulate  in  the  therapeutic  treatment  of  blood  and  bleeding  disorders,  such  as  hemophilia.  The  lead  candidate  in  this  collaboration  is  a
longer-acting form of a recombinant Factor VIII (“rFVIII”) protein.

This agreement has been amended several times since 2005, most recently in January 2014. The January 2014 amendment provides
for  increased  future  development,  regulatory,  sales  and  deadline  extension  receipts,  restructured  target  deadlines  and  royalty  receipts  on
potential  net  sales.  The  Company  is  entitled  to  up  to  $100  million  in  potential  development,  regulatory,  sales  and  deadline  extension
receipts,  which  are  contingent  on  the  performance  of  Baxter  achieving  certain  milestones.  The  Company  is  also  entitled  to  royalties  on
potential net sales varying by country of sale. The Company’s right to receive these royalties in any particular country will expire upon the
later of ten years after the first commercial sale of the product in that country or the expiration of patent rights in that particular country. In
connection with this amendment, Baxter SA also made a $10 million equity investment in the Company in exchange for 10,695,187 shares
of the Company’s common stock during January 2014.

Through December 31, 2014, the Company and Baxter continued to engage in research and development activities with no resultant
commercial  products.  $1  million  was  received  and  recognized  as  revenue  during  the  year  ended  December  31,  2013  related  to  this
collaboration as the Company’s continued performance or future obligations were considered inconsequential or perfunctory. No revenue
was recognized during the year ended December 31, 2014.

Baxter is a related party of the Company, with a share ownership of approximately 8.7% and 1.8% of the total issued common stock

as of December 31, 2014 and 2013, respectively.

SynBio LLC

In August,  2011,  SynBio  LLC  (“SynBio”)  and  the  Company  entered  into  a  stock  subscription  and  collaborative  development  of
pharmaceutical products agreement (the “Co-Development Agreement”). The Company granted an exclusive license to SynBio to develop
pharmaceutical products using certain molecule(s) based on SynBio’s technology and the Company’s proprietary technology (PolyXen ®,
OncoHist™ and ImuXen®) that prolongs the active life and/or improves the pharmacokinetics of certain therapeutic proteins and peptides
(as  well  as  conventional  drugs).  In  return,  SynBio  granted  an  exclusive  license  to  the  Company  to  use  the  pre-clinical  and  clinical  data
generated by SynBio in certain agreed products and engage in the development of commercial candidates.

SynBio and the Company are each responsible for funding their own research activities. There are no milestone or other research-
related  payments  due  under  the  agreement  other  than  fees  for  the  supply  of  each  company’s  respective  research  supplies  based  on  their
technology, which, when provided, are due to mutual convenience and not representative of an ongoing or recurring obligation to supply
research supplies. Most recently, similar to the Company’s agreement with Baxter, Serum Institute of India Limited (“Serum Institute”) has
agreed to directly provide the research supplies to SynBio, where the Company is not liable for any failure to supply the research supplies
as a result of any act or fault of Serum Institute’s. Upon successful commercialization of any resultant products, the Company is entitled to
receive royalties on sales in certain territories and pay royalties to SynBio for sales outside those certain territories.

Through December 31, 2014, the Company and SynBio continued to engage in research and development activities with no resultant
commercial products. The Company did not recognize revenue in connection with the Co-Development Agreement during the years ended
December 31, 2014 and 2013.

SynBio is an affiliate of the Company, with a share ownership of approximately 41.6% and 45.3% of the total issued common stock
as of December 31, 2014 and 2013, respectively. On December 31, 2014, the Company granted SynBio a warrant to purchase 6,745,000
shares of common stock in connection with ongoing collaborative activities. See Note 9, Stockholders’ Equity, for further information on
the warrant.

Serum Institute of India Limited

In the period from 2004 through 2011, the Company entered into and amended certain license and supply agreements with Serum
Institute. The original license agreement with Serum Institute was a collaborative Development and Manufacturing Arrangement (“DMA”)
to  develop  agreed  upon  potential  commercial  product  candidates  using  the  Company’s  PolyXen ®  technology.  Serum  Institute  then
endeavored  to  further  develop  the  potential  commercial  product  candidates  and  eventually  initiate  pre-clinical  and  clinical  trials  at  their
own  cost.  The  agreement  was  amended  in  2011,  resulting  in  the  surrender  of  development  rights  for  14  potential  commercial  product
candidates in 2012, which were vested to Serum Institute under the terms of the previous agreements, back to the Company.

Following the 2011 amendment, Serum Institute retained an exclusive license to use the Company’s PolyXen® technology to research
and  develop  one  potential  commercial  product,  Polysialylated  Erythropoietin  (“PSA-EPO”).  Serum  Institute  will  be  responsible  for
conducting all pre-clinical and clinical trials required to achieve regulatory approvals within the certain predetermined territories at Serum
Institute’s own expense. The royalty payment schedule based on net revenues on the future commercial sales of PSA-EPO under the DMA
was also modified as a result of the 2011 amendment. Royalty payments are payable by Serum Institute to the Company for net sales to
certain  customers  in  the  Serum  Institute  sales  territory.  Royalty  payments  are  payable  by  the  Company  to  Serum  Institute  for  net  sales
received by the Company over the term of the license. There are no milestone or other research-related payments due under the DMA.

Through December 31, 2014, the Company and Serum Institute continued to engage in research and development activities with no
resultant commercial products. No royalty revenue or expense was recognized by the Company related to the Serum Institute arrangement
during the years ended December 31, 2014 and 2013.

Serum  Institute  is  a  related  party  of  the  Company,  with  a  share  ownership  of  approximately  9.2%  and  10.6%  of  the  total  issued
common stock as of December 31, 2014 and 2013, respectively. On December 31, 2014, the Company granted Serum Institute a warrant to
purchase  3,200,000  shares  of  common  stock  in  connection  with  ongoing  collaborative  activities.  See  Note  9, Stockholders’  Equity,  for
further information on the warrant.

OJSC Pharmsynthez

In November 2011, the Company entered into a collaborative research and development license agreement with OJSC Pharmsynthez
(the  “Pharmsynthez  Arrangement”)  pursuant  to  which  the  Company  granted  an  exclusive  license  to  Pharmsynthez  to  develop,
commercialize and market six product candidates based on the Company’s PolyXen® and ImuXen® technology in certain territories. In
exchange, Pharmsynthez granted an exclusive license to the Company to use any pre-clinical and clinical data developed by Pharmsynthez,
within  the  scope  of  the  Pharmsynthez  Arrangement,  and  to  engage  in  further  research,  development  and  commercialization  of  drug
candidates outside of certain territories at the Company’s own expense.

impairment review, the fair value of the Company’s goodwill balance significantly exceeded its carrying value.

Indefinite-Lived Intangible Assets

The Company’s acquired indefinite-lived intangible asset, OncoHist™, is IPR&D relating to the Company’s business combination
with SymbioTec. As of October 1, 2014 and 2013, the dates of the Company’s annual impairment review, the fair value of the Company’s
indefinite-lived  intangible  asset  balance  was  $14.61  million  and  $10.40  million,  respectively,  which  exceeded  its  carrying  value  by
approximately  44%  and  1%,  respectively.  The  carrying  value  of  OncoHist™  was  $9.75  million  and  $10.32  million  as  of  December  31,
2014  and  2013,  respectively.  No  impairment  was  recorded  during  the  years  ended  December  31,  2014  and  2013.  The  changes  in  the
carrying value reflected herein are solely comprised of the effects of changes in foreign currency.

Excess Earnings Method (“MPEEM”), which is a form of the income approach, using Level 3 inputs under the fair value hierarchy. Under
the  MPEEM,  the  fair  value  of  an  intangible  asset  is  equal  to  the  present  value  of  the  asset’s  incremental  after-tax  cash  flows  (excess
earnings) remaining after deducting the market rates of return on the estimated value of contributory assets (contributory charge) over its
remaining useful life. This method requires the Company to make long-term projections of the amount and timing of income and expenses
related to development and commercialization of the acquired intangible asset and assumptions regarding the rate of return on contributory
assets, the weighted average cost of capital and the discount rate for estimated future after-tax cash flows. Specifically, this method took
into account the Company’s estimates of future incremental milestone payments that may be achieved upon completion of certain clinical
trial stages, regulatory approval and sales goals upon commercialization, as well as the Company’s expected royalty income based on sales
upon commercialization. Projected expenses are based on the Company’s forecasted budget required to complete the development of the
IPR&D and are estimates subject to change based on several factors including the results of clinical trials and delays in regulatory approval.
The  discount  rate  used  is  commensurate  with  the  uncertainties  associated  with  the  economic  estimates  described  above  and  reflects  the
stage  of  development,  the  time  and  resources  needed  to  complete  the  development  of  the  product  and  the  risks  of  advancement  through
regulatory approval processes.

OncoHist™ is not yet commercialized and has not yet begun to be amortized as of December 31, 2014.

The  Company  accounts  for  income  taxes  using  the  liability  method  under  ASC  Topic  740,  Income  Taxes.  Under  this  method,
deferred tax assets and liabilities are determined based on temporary differences resulting from the different treatment of items for tax and
financial reporting purposes. 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 reverse. Additionally, the Company must assess the likelihood that deferred
tax  assets  will  be  recovered  as  deductions  from  future  taxable  income.  The  Company  has  provided  a  full  valuation  allowance  on  the
Company’s deferred tax assets because the Company believes it is more likely than not that its deferred tax assets will not be realized. The
Company evaluates the recoverability of its deferred tax assets on a quarterly basis. Currently, there is no provision for income taxes as the
Company has incurred losses to date.

The components of (loss) before income taxes are as follows:

For  the  years  ended  December  31,  2014  and  2013,  the  Company  had  UK  net  operating  loss  carryforwards  of  $45.99  million  and
$41.7 million, respectively, US federal net operating loss carryforwards of $2.95 million and $692,153, respectively, US state net operating
loss  carryforwards  of  $2.92  million  and  $690,942,  respectively,  and  Germany  net  operating  loss  carryforwards  of  approximately  $1.25
million and $1.14 million, respectively. The UK and Germany net operating loss carryforwards can be carried forward indefinitely. The US
federal and state net operating loss carryforwards begin to expire in 2032.

The Company’s ability to use its operating loss carryforwards and tax credits generated in the US to offset future taxable income is
subject to restrictions under Section 382 of the United States Internal Revenue Code (the “Internal Revenue Code”). These restrictions may
limit the future use of the operating loss carryforwards and tax credits if certain ownership changes described in the Internal Revenue Code
occur.  Future  changes  in  stock  ownership  may  occur  that  would  create  further  limitations  on  the  Company’s  use  of  the  operating  loss
carryforwards and tax credits. In such a situation, the Company may be required to pay income taxes, even though significant operating loss
carryforwards and tax credits exist.

The Company’s ability to use its operating loss carryforwards and tax credits generated in the UK are subject to restrictions under UK
tax legislation. These regulations may limit the future use of operating loss carryforwards if there is a change in ownership and a change in
the  nature  or  conduct  of  the  business  carried  on  by  the  Company,  and  in  certain  circumstances  where  there  is  a  change  in  the  nature  or
conduct of the business only. In such cases the carryforwards would cease to be available to set against future income.

The Company’s ability to use its operating loss carryforwards and tax credits generated in Germany are also subject to restrictions
under German tax legislation. These regulations may limit the future use of operating loss carryforwards if there is a change in ownership.
In such cases the carryforwards would cease to be available to set against future income.

As of December 31, 2014 and 2013, the Company recorded uncertain tax positions of zero and $185,961, respectively, due to a claim
for research and development tax credits. A full valuation allowance has been provided against the Company’s research and development
credits in 2013. In 2014, the Company determined that it is unable to obtain and compile the necessary information to support and defend
the  recoverability  of  the  research  and  development  tax  credits,  resulting  in  the  write-off  of  the  previously  fully  reserved  balance.  The
changes to uncertain tax positions for 2014 and 2013 were as follows:

Uncertain tax benefits as of January 1
Gross adjustments in tax positions
Gross increases
Foreign currency translation

The Company files income tax returns in the US federal tax jurisdiction and Massachusetts state tax jurisdiction, and certain foreign
tax jurisdictions. Since the Company is in a loss carryforward position, the Company is generally subject to examination by the US federal,
state, foreign, and local income tax authorities for all tax years in which a loss carryforward is available. The Company is not currently
under  examination  by  the  Internal  Revenue  Service.  Subject  to  the  research  and  development  tax  credit  claim  referred  to  above,  the
Company  is  not  currently  under  examination  by  any  other  jurisdiction  for  these  years.  The  Company  has  not  recorded  any  interest  or
penalties for unrecognized tax benefits since its inception.

Stockholders’ Equity

Common Stock

Each  share  of  common  stock  entitles  the  holder  to  one  vote  on  all  matters  submitted  to  a  vote  of  the  Company’s  stockholders.
Common  stockholders  are  entitled  to  dividends  when  and  if  declared  by  the  Board  of  Directors.  In  the  event  of  any  voluntary  or
involuntary liquidation, dissolution or winding-up of the Company, the holders of common stock are entitled to share ratably in the assets
of the Company available for distribution.

On January 30, 2014, the Company announced the amendment of the licensing agreement with Baxter in which certain financial and
timing aspects of the agreement were modified. As a result, the Company is entitled to receive certain amounts in development, regulatory
and sales milestone payments as well as increased royalties on potential net sales. In addition, Baxter SA made a direct equity investment of
$10  million  in  cash  in  exchange  for  10,695,187  shares  of  the  Company’s  common  stock.  See  Note  4, Significant  Strategic  Drug
Development Collaborations, for further discussion on the Company’s collaboration agreement with Baxter.

On December 31, 2014, 3,244,784 shares of new common stock were granted to FDS Pharma ASS (“FDS”) in consideration for the
performance of services and termination of a prior collaboration agreement between Lipoxen and FDS. The Company determined that the
fair value of the shares of common stock granted is more reliably measurable than the fair value of the services received. The Company
assessed the fair value of one share of common stock on the measurement date to be $0.25, which is the Company’s quoted price per share
of  common  stock  on  the  OTCQB  marketplace  exchange  on  December  31,  2014. As  performance  by  FDS  was  complete  at  the  issuance
date,  the  Company  recorded  expense  of  approximately  $812,000  to  research  and  development  expense  in  the  consolidated  statement  of
comprehensive loss during the year ended December 31, 2014. FDS is a related party of SynBio, an affiliate of the Company.

Warrants

In connection with the Company’s collaboration agreements, the Company issued warrants to purchase shares of common stock to its
collaborative  partners. A  warrant  was  also  issued  to  a  non-employee  director  for  consulting  services  provided  to  the  Company.  These
warrants were fair valued at issuance date using the Black-Scholes option pricing model. The warrants are subject to re-measurement at
each reporting period until the measurement date is reached. Expense is recognized on a straight-line basis over the expected service period
or at the date of issuance, if there is not a service period.

In 2010, Baxter SA was granted a warrant to purchase 4,588,298 new shares of common stock, which were exercisable immediately
after issuance and expire on June 30, 2015. These warrants, which were fair valued at $932,000 at the time of issuance, were outstanding as
of December 31, 2014 and 2013.

In 2011, Serum Institute was granted a warrant to purchase 2,400,000 new shares of common stock in three tranches of 800,000 each,
which are exercisable immediately after issuance and expire in a range of 6 to 18 months after issuance (“Serum Institute 2011 Warrant”).
The Serum Institute 2011 Warrant was fair valued at $10,000 at the time of issuance. The Serum Institute 2011 Warrant fully expired over
a period spanning 2012 and 2013. Serum Institute did not exercise any warrants during the year ended December 31, 2013. On December
31, 2014, Serum Institute was granted a warrant to purchase 3,200,000 new shares of common stock at an exercise price of $0.77 per share
(“Serum  Institute  2014  Warrant”).  The  Serum  Institute  2014  Warrant,  which  was  fair  valued  at  approximately  $480,000  at  the  time  of
issuance, is exercisable in two equal tranches, each with separate non-market, performance-based vesting criteria. The Company uses its
judgment  to  assess  the  probability  and  timing  of  Serum  Institute  achieving  this  vesting  criteria  and  estimated  that  it  is  probable  that  the
vesting criteria will be achieved for each tranche. These judgments are reassessed at each reporting period until the measurement date is
reached.

In  connection  with  the  Serum  Institute  2014  Warrant  grant,  warrants  to  purchase  160,000  aggregate  new  shares  of  common  stock
were issued to Serum Institute employees (“Serum Institute Partner Warrants”) on December 31, 2014 under the same terms and conditions
of  the  Serum  Institute  2014  Warrant.  The  Serum  Institute  Partner  Warrants  were  fair  valued  at  approximately  $24,000  at  the  time  of
issuance.  The  Serum  Institute  2014  Warrant  and  Serum  Institute  Partner  Warrants  expire  on  December  30,  2019  and  no  warrants  were
exercised during the year ended December 31, 2014.

In 2011, SynBio was granted a warrant to purchase 3,545,600 new shares of common stock, which was exercisable two years after
issuance and expires on December 2, 2016 (“SynBio 2011 Warrant”). The SynBio 2011 Warrant, which was fair valued at $108,000 at the
time of issuance, was outstanding as of December 31, 2013. On December 31, 2014, SynBio was granted a warrant to purchase 6,745,000
new shares of common stock at an exercise price of $0.77 per share (“SynBio 2014 Warrant”). The SynBio 2014 Warrant is exercisable in
four  equal  tranches,  each  with  separate  non-market,  performance-based  vesting  criteria.  The  Company  uses  its  judgment  to  assess  the
probability and timing of SynBio achieving this vesting criteria and estimated that it is probable that the vesting criteria will be achieved
for two of the defined tranches. The warrant tranches expected to vest were fair valued at approximately $506,000 at the time of issuance,
The two tranches with vesting criteria not probable to be achieved will not be initially recognized. These judgments are reassessed at each
reporting  period  until  the  measurement  date  is  reached.  Upon  issuance  of  the  SynBio  2014  Warrant  on  December  31,  2014,  the  SynBio
2011 Warrant was canceled and of no further force and effect.

In connection with the SynBio 2014 Warrant grant, warrants to purchase 320,000 aggregate new shares of common stock were issued
to  SynBio  and  Pharmsynthez  non-director  designees  (“SynBio  Partner  Warrants”)  on  December  31,  2014  under  the  same  terms  and
conditions of the SynBio 2014 Warrant. The SynBio Partner Warrants were fair valued at approximately $24,000 at the time of issuance.
The SynBio 2014 Warrant expires on December 30, 2019 and no warrants were exercised during the year ended December 31, 2014.

On December 31, 2014, a non-employee director was granted a warrant to purchase 1,600,000 new shares of common stock at an
exercise price of $0.77 per share for services provided to the Company. This warrant, which was fair valued at approximately $240,000 at
the time of issuance, is exercisable two years after issuance. As performance was completed and the measurement date reached at the time
of  issuance,  the  Company  recorded  expense  of  approximately  $240,000  to  general  and  administrative  expenses  in  the  consolidated
statement  of  comprehensive  loss  during  the  year  ended  December  31,  2014.  This  warrant  expires  on  December  30,  2019  and  was  still
outstanding as of December 31, 2014.

Key assumptions used in the Black-Scholes option pricing model for warrants granted during the year ended December 31, 2014 are

Stock Option Modification

Prior  to  the Acquisition,  the  Company  had  two  incentive  stock  plans,  the  Lipoxen  plc  Unapproved  Share  Option  Plan  (the  “2000
Stock Plan”) and the Xenetic Biosciences plc 2007 Share Option Scheme (the “2007 Stock Plan”). Subsequent to the Acquisition, the 2000
and 2007 Stock Plans were converted to reflect the new shares issued by the Company under the Scheme of Arrangement related to the
Acquisition. As  part  of  the  conversion,  option  holders  under  the  2000  and  2007  Stock  Plan  have  the  right  to  subscribe  for  a  number  of
shares of common stock in the Company (the “Replacement Option Shares”) in exchange for the cancellation and surrender by the option
holder of the original options granted by the 2000 and 2007 Stock Plans. The number of Replacement Option Shares is determined in the
same manner in which the shareholders of Xenetic UK were given the right to acquire shares of common stock in the Company according
to the Acquisition. The aggregate exercise price payable in US dollars for Replacement Option Shares is the same as the aggregate exercise
price  in  pounds  sterling  of  the  original  options,  using  a  foreign  currency  exchange  rate  for  pounds  sterling  into  US  dollars  quoted  by
Barclays Bank plc at 12 noon Greenwich Mean Time (“GMT”) on January 23, 2014, the date of the Acquisition. The conversion of the
options is treated as an option modification. The Company accounted for the option modification under ASC Topic 718,  Compensation –
Stock Compensation, and determined the option modification does not result in incremental stock compensation cost that is material to the
Company’s results of operations during the year ended December 31, 2014.

Stock Options

The  Company  grants  stock  option  awards  to  employees  and  non-employees  with  varying  vesting  terms  under  the  Xenetic
Biosciences,  Inc.  Equity  Incentive  Plan  (“Stock  Plan”).  The  Company  measures  the  fair  value  of  stock  option  awards  using  the  Black-
Scholes option pricing model, which uses the assumptions noted in the tables below, including the risk-free interest rate, expected term,
share price volatility, dividend yield and forfeiture rate. The risk-free interest rate is based upon the US Treasury yield curve in effect at the
time  of  grant,  with  a  term  that  approximates  the  expected  life  of  the  option.  For  employee  stock  options  issued  in  2014  that  qualify  as
“plain  vanilla”  stock  options  in  accordance  with  Staff Accounting  Bulletin  No.  110  (“SAB  110”),  the  expected  term  is  based  on  the
simplified  method,  as  defined  by  SAB  110.  The  Company  has  a  limited  history  of  stock  option  exercises,  which  does  not  provide  a
reasonable  basis  for  the  Company  to  estimate  the  expected  term  of  employee  stock  options.  For  all  other  employee  stock  options,  the
Company  estimates  the  expected  life  using  judgment  based  on  the  anticipated  research  and  development  milestones  of  the  Company’s
clinical  projects  and  behaviour  of  the  Company’s  employees.  The  expected  life  of  non-employee  options  is  the  contractual  life  of  the
option.  The  Company  determines  the  expected  volatility  based  on  a  weighted-average  of  the  historical  volatility  of  a  peer  group  of
comparable publicly traded companies with product candidates in similar stages of development to the Company’s product candidates in
conjunction with the Company’s historical volatility. The Company has applied an expected dividend yield of 0% as the Company has not
historically declared a dividend and does not anticipate declaring a dividend during the expected life of the options. Further, the Company
has applied a forfeiture rate of 0% as the Company has not historically experienced forfeitures. During 2013, approximately two million
options  were  forfeited  by  a  management  executive  as  a  result  of  his  unanticipated  short  period  of  employment;  however,  the  Company
views this situation to be an independent event and does not expect this type of forfeiture to reoccur in the future.

Employee Stock Options

During the years ended December 31, 2014 and 2013, 1.08 million and 2.30 million total stock options to purchase shares of common
stock were granted under the Stock Plan, respectively, with a weighted average grant date fair value per option share of $0.23 and $0.07,
respectively. During the years ended December 31, 2014 and 2013, 1,984,080 and 55,379 stock options were exercised, respectively, and
cash received from those stock option exercises was $101,933 and $2,090, respectively.

During the year ended December 31, 2014 and 2013, 0.68 million and 0.45 million total stock options vested, with total fair values of
$115,864 and $63,616, respectively. As of December 31, 2014, there was $199,286 of unrecognized share-based compensation related to
employee  stock  options  that  are  expected  to  vest.  The  Company  expects  to  recognize  this  expense  over  a  weighted-average  period  of
approximately two years.

Share-based compensation expense related to stock options granted to non-employees is recognized as the services are rendered on a
straight-line basis. The Company determined that the fair value of the stock options is more reliably measurable than the fair value of the
services received. Compensation expense related to stock options granted to non-employees is subject to re-measurement at each reporting
period until the options vest.

During the years ended December 31, 2014 and 2013, 480,000 and zero non-employee stock options were granted under the Stock
Plan, respectively, with a weighted average grant date fair value per option share of $0.23 and zero, respectively. No non-employee stock
options were exercised during years ended December 31, 2014 and 2013.

The Company granted common stock awards to a non-employee in exchange for services provided. The Company measured the fair
value of these awards using the fair value of the services provided as it is a more reliable measure of the fair value of the awards. The fair
value  measurement  date  of  these  awards  is  generally  the  date  the  performance  of  services  is  complete.  The  fair  value  of  the  awards  is
recognized as services are rendered on a straight-line basis.

The  Company  granted  187,406  and  282,508  common  stock  awards  during  the  years  ended  December  31,  2014  and  2013,
respectively, in exchange for professional services. As all services were rendered in each respective period, compensation expense related
to common stock awards of $102,000 and $85,825 was recognized during the years ended December 31, 2014 and 2013, respectively. All
common stock awards were authorized but not issued as of December 31, 2014.

Joint Share Ownership Plan

In  2010  and  2012,  the  Company  issued  1,701,913  and  8,986,281  JSOP  awards,  respectively,  to  two  senior  executives  under  the
JSOP. Under the JSOP, shares in the Company are jointly purchased at fair market value by the participating executives and the trustees of
the JSOP trust, with such shares held in the JSOP trust. For US GAAP purposes the awards are valued as employee options.

The JSOP trust holds the shares of the JSOP until such time as the JSOP shares are vested and the participating executives exercise
their rights under the JSOP. The JSOP trust is granted an interest bearing loan by the Company in order to fund the purchase of its interest
in the JSOP shares. The loan held by the trust is eliminated on consolidation in the financial statements of the Company. The Company
funded portion of the share purchase price is deemed to be held in treasury until such time as they are transferred to the employee and is
recorded as a reduction in equity.

The  exercise  price  of  the  “option”  is  deemed  to  be  the  market  value  of  the  shares  at  the  date  of  issue.  The  awards  vest  based  on
certain  market  conditions,  which  require  each  tranche  of  shares  to  meet  specific  share  price  hurdles,  or  change  in  control  conditions,  as
defined by the plan. Under the JSOP and subject to the vesting of the participants’ interest, participating executives will, when the JSOP
shares are sold, be entitled to a share of the proceeds of sale equal to the growth in market value of the JSOP shares versus the exercise
price, less simple interest on the original share purchase price, net of executives’ cash contribution at inception, as agreed for each grant
(the “Carry Charge”). The balance of the proceeds will remain to the benefit of the JSOP trust and be applied to the repayment of the loan
originally made by the Company to the JSOP trust. Any funds remaining in the JSOP trust after settlement of the loan and any expenses of
the JSOP trust are for the benefit of the Company.

The  Company  measures  the  fair  value  of  the  awards  using  Monte  Carlo  simulations,  which  requires  estimates  based  on  the
Company’s judgment as well as other assumptions. These estimates include the expected term of each tranche of the JSOP awards, which
the Company determined to be the initial life of the awards, and expected volatility, which is based on a weighted-average of the historical
volatility  of  a  peer  group  of  comparable  publicly  traded  companies  with  product  candidates  in  similar  stages  of  development  to  the
Company’s  product  candidates  in  conjunction  with  the  historical  volatility  of  Xenetic  Biosciences  plc’s  shares  when  traded  on  the  UK
Alternative Investment Market. The Company has applied an expected dividend yield of 0% as the Company has not historically declared a
dividend and does not anticipate declaring a dividend during the expected life of the awards. The risk-free interest rate is based upon the
U.S. Treasury yield curve in effect at the time of grant, with a term that approximates the expected life of the awards. The compensation
expense is recorded over the expected life of the  option,  regardless  of  whether  the  awards  vest.  Having  established  the  full  value  of  the
JSOP awards using the Monte Carlo simulation outlined above, a deduction is made in respect of the anticipated Carry Charge in order that
the expense recorded in the financial statements only represents the participating executives’ net interest in the awards.

On  exercise  of  the  JSOP  awards  by  the  executives  the  Carry  Charge  due  to  the  Company  will  be  recognized  as  additional  paid-in

capital, arising from the sale of treasury stock.

During 2011, the 2010 JSOP awards fully vested under the terms of the JSOP due to a significant change in beneficial ownership of
the  Company  and  the  related  compensation  charges  were  fully  recorded  during  periods  prior  to  2013  related  to  this  accelerated  vesting.
During the first quarter of 2014, the 2012 JSOP awards fully vested under the terms of the JSOP due the achievement  of  specific  share
price hurdles and the related compensation charges were fully recorded during the first quarter of 2014 related to this accelerated vesting.
As of December 31, 2014, all JSOP awards were fully vested.

The  total  fair  value  of  the  2012  JSOP  awards  was  $853,889  at  the  date  of  issuance.  The  Company  recognized  $344,905  and

$279,484 of compensation costs during the years ended December 31, 2014 and 2013.

11. Employee Benefit Plans

The  Company  has  a  defined  contribution  401(k)  savings  plan  (the  “401(k)  Plan”).  The  401(k)  Plan  covers  substantially  all  US
employees, and allows participants to defer a portion of their annual compensation on a pre-tax basis. Company contributions to the 401(k)
Plan may be made at the discretion of the Board of Directors. During the year ended December 31, 2014 and 2013, the Company made
$31,738 and zero contributions to the 401(k) Plan.

In the UK, the Company has adopted a defined contribution plan (the “UK Plan”) which qualifies under the rules established by HM
Revenue & Customs. The UK Plan generally allows all UK employees to contribute a minimum of 3% of salary with no maximum limit.
The  Company  contributes  to  the  plan  between  8%  and  12%  of  the  employee’s  salary,  depending  upon  seniority  of  the  employee.  The
Company, at its discretion, may also contribute to an employee’s personal pension plan. The Company paid total contributions of $108,439
and $129,353 during the years ended December 31, 2014 and 2013, respectively.

12. Commitments

In August 2013, the Company entered into an agreement to lease office and laboratory space in Lexington, Massachusetts under an
operating lease with a commencement date of January 1, 2014 and a termination date of January 31, 2019. With the execution of this lease,
the Company is required to maintain a $66,000 letter of credit as a security deposit. In connection with the Lexington lease, the Company
recorded $120,299 as prepaid rent as of December 31, 2014, with $90,838 recorded as a non-current asset. The Company also incurred a
liability of $89,074 with respect to the Company’s contribution to the landlord’s leasehold improvements, of which $73,117 is outstanding
as of December 31, 2014, with $56,383 recorded as a non-current liability. This liability is repayable as additional rent expense over the
term of the lease and bears interest at 6%. In addition, the Company leases office space in London, UK, which is due to expire in March
2017. In September 2014, the Company served notice to the landlord of the office space in London in accordance with the terms of the
break  clause  in  the  lease,  with  an  expected  termination  date  in  March  2015.  The  Company  also  leased  laboratory  space  in  London,  UK
during 2013, however this lease was terminated in December 2013.

13. Related Party Transactions

In  May  2011,  the  Company  received  a  short  term  unsecured  loan  facility  of  up  to  $1.7  million  from  SynBio,  an  affiliate  of  the
Company, of which $395,000 and $681,124 was outstanding as of December 31, 2014 and 2013, respectively. A payment of $286,124 on
the  outstanding  loan  was  made  to  SynBio  during  the  year  ended  December  31,  2014.  No  payments  were  made  during  the  year  ended
December 31, 2013. The loan had an interest rate of 8.04% per annum as of the date of grant, with interest payable upon repayment of the
loan, which was to be seven months after the closing date of the loan. During 2012, the loan matured and it was agreed by both parties that
the  loan  can  be  called  due  with  full  repayment  of  the  outstanding  principal  including  accrued  interest  upon  future  agreement  by  both
parties. It was also agreed at this point that as of July 1, 2012, no further interest on the outstanding loan balance will be accrued. The loan
is recorded in “Loans due to related parties” within current liabilities as of December 31, 2014 and 2013. The loan does not bear interest at
the prevailing market rate for instruments with similar characteristics.

During the year ended December 31, 2014, the Company also received consulting and patent legal services from a firm owned by a
non-employee director of the Company. The total amount of services received was $133,381 for the year ended December 31, 2014, with
$51,708 included in accounts payable on the consolidated balance sheet as of December 31, 2014. No services were received by the firm in
2013.

Please  refer  to  Note  4,  Significant  Strategic  Drug  Development  Collaborations,  and  Note  9,  Stockholder’s  Equity,  for  details  on

arrangements with collaboration partners and non-employee directors that are also related parties.

DISCLOSURE

The  Company,  as  reported  in  its  Current  Report  filed  on  Form  8-K  on April  10,  2014,  changed  its  accountants  to  Ernst  &  Young

LLP. The Company has no disagreements with the current or predecessor accountants on any accounting and financial disclosure matters.

ITEM 9A – CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of
our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended
(the “Exchange Act”), as of the end of the period covered by this Annual Report on Form 10-K.

Based on this evaluation our management, including our Chief Executive Officer and Chief Financial Officer concluded that, as of
the end of the period covered by this Annual Report on Form 10-K, our disclosure controls and procedures are designed at a reasonable
assurance  level  and  are  effective  to  provide  reasonable  assurance  that  information  we  are  required  to  disclose  in  reports  that  we  file  or
submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and
forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief
Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Management’s 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  Rule  13a-15(f)  of  the  Exchange Act.  Management  under  the  supervision  and  with  the  participation  of  our  Chief  Executive
Officer and Chief Financial Officer, conducted an assessment of the design and effectiveness of our internal control over financial reporting
as  of  the  end  of  the  period  covered  by  this Annual  Report  on  Form  10-K.  In  making  its  assessment  of  internal  control  over  financial
reporting, management used the criteria set forth by the Committee of Sponsoring Organizations (“COSO”) of the Treadway Commission
in Internal  Control  —  Integrated  Framework.  Based  on  this  assessment,  our  management  concluded  that,  as  of  the  end  of  the  period
covered by this Annual Report on Form 10-K, our internal control over financial reporting was effective based on the criteria set forth by
COSO of the Treadway Commission in Internal Control — Integrated Framework.

This  annual  report  does  not  include  an  attestation  report  of  our  registered  public  accounting  firm  regarding  internal  control  over
financial reporting. Management’s report was not subject to attestation by our registered public accounting firm pursuant to an exemption
for non-accelerated filers set forth in Section 989G of the Dodd-Frank Wall Street Reform and Consumer Protection Act.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting that occurred during the period covered by this Annual
Report  on  Form  10-K  that  have  materially  affected,  or  are  reasonably  likely  to  materially  affect,  our  internal  control  over  financial
reporting.

73

 
 
 
 
 
 
 
 
 
 
 
 
 
Limitations on Effectiveness of Controls and Procedures

In  designing  and  evaluating  the  disclosure  controls  and  procedures,  management  recognizes  that  any  controls  and  procedures,  no
matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. The Company’s
internal control over financial reporting includes those policies and procedures that:

(1)

(2)

(3)

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

Management,  including  the  Company’s  Chief  Executive  Officer  and  Chief  Financial  Officer,  does  not  expect  that  the  Company’s
internal controls will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide
only  reasonable,  not  absolute,  assurance  that  the  objectives  of  the  control  system  are  met.  Further,  the  design  of  a  control  system  must
reflect  the  fact  that  there  are  resource  constraints,  and  the  benefits  of  controls  must  be  considered  relative  to  their  costs.  Because  of  the
inherent  limitations  in  all  control  systems,  no  evaluation  of  internal  controls  can  provide  absolute  assurance  that  all  control  issues  and
instances of fraud, if any, have been detected. Also, any evaluation of the effectiveness of controls in future periods are subject to the risk
that those internal controls may become inadequate because of changes in business conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

Schedule 1

Representations, Warranties and Covenants of FDS

1.              Organization; Authority. FDS is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction
of its organization with the requisite limited partnership power and authority to enter into and to consummate the transactions contemplated
by this Agreement and otherwise to carry out its obligations hereunder. The execution and delivery of this Agreement by FDS and
performance by FDS of the transactions contemplated by this Agreement have been duly authorized by all necessary limited partnership or
other applicable like action, on the part of FDS. This Agreement has been duly executed by FDS, and when delivered by FDS in
accordance with the terms hereof, will constitute the valid and legally binding obligation of FDS, enforceable against it in accordance with
its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or
similar laws relating to, or affecting generally the enforcement of, creditors' rights and remedies or by other equitable principles of general
application.

2.              No Conflicts. The execution, delivery and performance by FDS of this Agreement and the consummation by FDS of the
transactions contemplated hereby will not (i) result in a violation of the organizational documents of FDS, (ii) conflict with, or constitute a
default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination,
amendment, acceleration or cancellation of, any agreement, indenture or instrument to which FDS is a party, or (iii) result in a violation of
any law, rule, regulation, order, judgment or decree (including federal and state securities laws) applicable to FDS, except in the case of
clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which would not, individually or in the aggregate, reasonably be
expected to have a material adverse effect on the ability of FDS to perform its obligations hereunder.

3.              Investment Intent. FDS understands that the Shares are "restricted securities" and have not been registered under the Securities
Act of 1933, as amended (the "Securities Act") or any applicable state securities law and is acquiring the Shares as principal for its own
account and not with a view to, or for distributing or reselling such Shares or any part thereof in violation of the Securities Act or any
applicable state securities laws. FDS is acquiring the Shares hereunder in the ordinary course of its business. FDS does not presently have
any agreement, plan or understanding, directly or indirectly, with any person to distribute or effect any distribution of any of the Shares (or
any securities which are derivatives thereof) to or through any person or entity; FDS is not a registered broker-dealer under Section 15 of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or an entity engaged in a business that would require it to be so
registered as a broker-dealer.

4.              Investor Status. At the time FDS was offered the Shares, it was, and at the date hereof it is, either (i) an "accredited investor" as
defined in Rule 501(a) under the Securities Act or (ii) not a "U.S. person" as defined in Rule 902 of Regulation S of the Securities Act.

5.              General Solicitation. FDS is not purchasing the Shares as a result of any advertisement, article, notice or other communication
regarding the Shares published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any
seminar or any other general advertisement.

18

 
 
 
 
 
 
 
 
 
6.             Experience of FDS. FDS, either alone or together with its representatives, has such knowledge, sophistication and experience in
business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Shares, and has so
evaluated the merits and risks of such investment. FDS is able to bear the economic risk of an investment in the Shares and, at the present
time, is able to afford a complete loss of such investment.

7.             Access to Information. FDS acknowledges that it has been afforded (i) the opportunity to ask such questions as it has deemed
necessary of, and to receive answers from, representatives of Xenetic concerning the terms and conditions of the offering of the Shares and
the merits and risks of investing in the Shares; (ii) access to information about Xenetic and its subsidiaries and their respective financial
condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment; and (iii)
the opportunity to obtain such additional information that Xenetic possesses or can acquire without unreasonable effort or expense that is
necessary to make an informed investment decision with respect to the investment. FDS has sought such accounting, legal and tax advice as
it has considered necessary to make an informed decision with respect to its acquisition of the Shares.

8.             Brokers and Finders. No person will have, as a result of the transactions contemplated by this Agreement, any valid right, interest
or claim against or upon Xenetic or FDS for any commission, fee or other compensation pursuant to any agreement, arrangement or
understanding entered into by or on behalf of FDS.

9.             Independent Investment Decision. FDS has independently evaluated the merits of its decision to purchase Shares pursuant to this
Agreement. FDS understands that nothing in this Agreement or any other materials presented by or on behalf of Xenetic to it in connection
with the purchase of the Shares constitutes legal, tax or investment advice. FDS has consulted such legal, tax and investment advisors as it,
in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Shares.

10.          Reliance on Exemptions. FDS understands that the Shares being offered and sold to it in reliance on specific exemptions from the
registration requirements of United States federal and state securities laws and that Xenetic is relying in part upon the truth and accuracy of,
and FDS's compliance with, the representations, warranties, agreements, acknowledgements and understandings of FDS set forth herein in
order to determine the availability of such exemptions and the eligibility of FDS to acquire the Shares.

11.          No Governmental Review. FDS understands that no United States federal or state agency or any other government or
governmental agency has passed on or made any recommendation or endorsement of the Shares or the fairness or suitability of the
investment in the Shares nor have such authorities passed upon or endorsed the merits of the offering of the Shares.

12.          Regulation M. FDS is aware that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of
Common Stock and other activities with respect to the Common Stock by FDS.

19

 
 
 
 
 
 
 
 
 
13.          Residency. FDS's offices in which its investment decision with respect to the Shares was made are located at the address
immediately below FDS name on its signature page hereto.

14.          FDS understands that the Shares and any securities issued in respect of or exchange for the Shares, may be notated with one or all
of the following legends:

"THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE
BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR
DISTRIBUTION THEREOF. NO SUCH TRANSFER MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION
STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT
SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933."

instrument, or book entry so legended.

Subject to the terms and conditions set forth herein, this Warrant shall be exercisable with respect to the vested portion as set forth
in Section 1, in whole or in part, during the term commencing at December 31, 2016 and ending at December 30, 2019; provided, however,
that the Holder shall not at any time exercise this Warrant if, and to the extent that, following such exercise, the Holder’s and/or the Concert
Party’s  aggregate  holdings  when  taken  together  would  exceed  [***]%  of  the  voting  shares  of  the  Company’s  capital  stock,  on  a  fully
diluted basis, on the proposed date of exercise. “Concert Party” means each of the Holder, [***].

Upon  issuance  of  this  Warrant,  the  warrant  dated August  4,  2011  issued  by  Lipoxen  Plc  to  Synbio  LLC  (which  warrant  was

assumed by the Company) shall be canceled automatically and be of no further force and effect.

The  Holder  further  agrees  that,  in  addition  to  any  other  applicable  transfer  restrictions  in  the  applicable  securities  laws  and

3. Exercise of Warrant.

a. Subject  to  the  terms  and  conditions  set  forth  herein,  the  purchase  rights  represented  by  this  Warrant  are  exercisable  by  the
Holder in whole or in part, from time to time, by the surrender of this Warrant and the Notice of Exercise attached hereto as
Exhibit A duly completed and executed on behalf of the Holder, at the office of the Company (or such other office or agency of
the Company as it may designate by notice in writing to the Holder at the address of the Holder appearing on the books of the
Company), upon payment in cash or by check acceptable to the Company of an amount equal to the aggregate Exercise Price of
the Warrant Shares being purchased.

b. This Warrant shall be deemed to have been exercised immediately prior to the close of business on the date of its surrender for
exercise as provided above, and the person entitled to receive the shares of Common Stock issuable upon such exercise shall be
treated  for  all  purposes  as  the  holder  of  record  of  such  shares  as  of  the  close  of business  on  such  date.  As  promptly  as
practicable on or after such date, the Company shall issue and deliver to the person or persons entitled to receive the same a
certificate  or  certificates  for  the  number  of  shares  issuable  upon  such  exercise.  In the  event  that  this  Warrant  is  exercised  in
part,  the  Company  will  execute  and  deliver  a  new  Warrant  of  like  tenor  exercisable  for  the  number  of  shares  for  which  this
Warrant may then be exercised.

4. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this
Warrant. In lieu of any fractional share to which the Holder would otherwise be entitled, the Company shall make a cash payment
equal to the Exercise Price multiplied by such fraction.

5. Replacement  of  Warrant .  On  receipt  of  evidence  reasonably  satisfactory  to  the  Company  of  the  loss,  theft,  destruction,  or
mutilation  of  this  Warrant  and,  in  the  case  of  loss,  theft,  or  destruction,  on  delivery  of  an  indemnity  agreement  reasonably
satisfactory in form and substance to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant, the
Company at its expense shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor and amount.

6. Rights of Stockholders. Until the Holder exercises this Warrant and the Company issues the Holder Warrant Shares purchasable
upon the exercise hereof, as provided herein, the Holder shall not be entitled to vote or receive dividends or be deemed the holder of
Common Stock or any other securities of the Company that may at any time be issuable on the exercise hereof for any purpose, nor
shall anything contained herein be construed to confer upon the Holder, as such, any of the rights of a shareholder of the Company
or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or
withhold  consent  or  assert  dissenter’s  rights  with  respect  to  any  corporate  action  (whether  upon  any  recapitalization,  issuance  of
stock,  reclassification  of  stock,  change  of  par  value,  or  change  of  stock  to  no  par  value,  consolidation,  merger,  conveyance,  or
otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise.

7. Market Stand-off. The Holder agrees that the Holder shall not sell or otherwise transfer, make any short sale of, grant any option
for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, of any shares of the
Company’s capital stock acquired through the exercise of this Warrant during the 180 day period following the commencement of
the  Company’s  public  offerings  (or  such  other  period  as  may  be  requested  by  the  Company  or  an  underwriter  to  accommodate
regulatory restrictions on (i)  the publication or other distribution of research reports and (ii) analyst recommendations and opinions).
The Holder further agrees that to the extent that the executive officers and directors of the Company are subject to a longer market
stand-off period, the Holder shall be subject to such longer market stand-off period as well. The Company may impose stop transfer
instructions and may stamp each certificate with a legend with respect to the shares subject to the foregoing restriction until the end
of such 180 day (or other) period. The Holder agrees to execute a market stand-off agreement with the underwriters in the offerings
in customary form consistent with the provisions of this section.

8. Representations  and  Warranties  of  the  Holder .  By  acceptance  of  this  Warrant,  the  Holder  represents  and  warrants  to  the

Company as follows:

a. Authority. The Holder represents that it has full power and authority to enter into this Warrant. This Warrant constitutes the
Holder’s  valid  and  legally  binding  obligation,  enforceable  in  accordance  with  its  terms,  except  as  may  be  limited  by  (i)
applicable bankruptcy, insolvency, reorganization, or similar laws relating to or affecting the enforcement of creditors’ rights
and (ii) laws relating to the availability of specific performance, injunctive relief or other equitable remedies.

b. No Conflicts. The execution, delivery and performance by the Holder of this Warrant and the consummation by the Holder of
the  transactions  contemplated  hereby  will  not  (i)   result  in  a  violation  of  the  organizational  documents  of  the  Holder,  (ii)
conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or
give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to
which the Holder is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal
and state securities laws) applicable to the Holder, except in the case of clauses (ii) and (iii) above, for such conflicts, defaults,
rights or violations which would not, individually or in the aggregate, reasonably be expected to have a material adverse effect
on the ability of the Holder to perform its obligations hereunder.

3

 
 
 
 
 
 
 
 
 
c.

Investment Intent. The Holder understands that this Warrant and the Warrant Shares (the “ Securities”) are “restricted securities”
and  have  not  been  and  will  not  be  registered  under  the  Securities Act  of  1933,  as  amended  (the  “Securities Act”)  or  any
applicable  state  securities  law  and  is  acquiring  the  Securities  as  principal  for  its  own  account  and  not  with  a  view  to,  or  for
distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable state securities
laws.  The  Holder  is  acquiring  the  Securities  hereunder  in  the  ordinary  course  of  its  business.  The  Holder  does  not  presently
have any agreement, plan or understanding, directly or indirectly, with any person to distribute or effect any distribution of any
of  the  Securities  (or  any  securities  which  are  derivatives  thereof)  to  or  through  any  person  or  entity;  the  Holder  is  not  a
registered  broker-dealer  under  Section  15  of  the  Securities  Exchange Act  of  1934,  as  amended  (the  “ Exchange Act”),  or  an
entity engaged in a business that would require it to be so registered as a broker-dealer.

d.

Investor Status. At the time the Holder was offered the Securities, it was, and at the date hereof it is, either (i) an “accredited
investor” as defined in Rule 501(a) under the Securities Act or (ii) not a “U.S. person” as defined in Rule 902 of Regulation S
of the Securities Act.

e. General  Solicitation.  The  Holder  is  not  acquiring  the  Securities  as  a  result  of  any  advertisement,  article,  notice  or  other
communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or
radio or presented at any seminar or any other general advertisement.

f.

Investment Experience.  The  Holder,  either  alone  or  together  with  its  representatives,  has  such  knowledge,  sophistication  and
experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment
in the Securities, and has so evaluated the merits and risks of such investment. The Holder is able to bear the economic risk of
an investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

g. Access to Information. The Holder acknowledges that it has been afforded (i) the opportunity to ask such questions as it has
deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the
offering of the Securities and the merits and risks of investing in the Securities; (ii)  access to information about the Company
and  its  subsidiaries  and  their  respective  financial  condition,  results  of  operations,  business,  properties,  management  and
prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the
Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment
decision  with  respect  to  the  investment.  The  Holder  has  sought  such  accounting,  legal  and  tax  advice  as  it  has  considered
necessary to make an informed decision with respect to its acquisition of the Securities.

4

 
 
 
 
 
 
 
h. Brokers and Finders. No person will have, as a result of the transactions contemplated by this Warrant, any valid right, interest
or claim against or upon the Company or the Holder for any commission, fee or other compensation pursuant to any agreement,
arrangement or understanding entered into by or on behalf of the Holder.

i.

Independent  Investment  Decision.  The  Holder  has  independently  evaluated  the  merits  of  its  decision  to  purchase  Securities
pursuant to this Warrant. The Holder understands that nothing in this Warrant or any other materials presented by or on behalf
of the Company to it in connection with the purchase of the Securities constitutes legal, tax or investment advice. The Holder
has  consulted  such  legal,  tax  and  investment  advisors  as  it,  in  its  sole  discretion,  has  deemed  necessary  or  appropriate  in
connection with its purchase of the Securities.

j. Reliance  on  Exemptions.  The  Holder  understands  that  the  Securities  being  offered  and  sold  to  it  in  reliance  on  specific
exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying
in  part  upon  the  truth  and  accuracy  of,  and  the  Holder’s  compliance  with,  the  representations,  warranties,  agreements,
acknowledgements and understandings of the Holder set forth herein in order to determine the availability of such exemptions
and the eligibility of the Holder to acquire the Securities.

k. No Governmental Review . The Holder understands that no United States federal or state agency or any other government or
governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability
of  the  investment  in  the  Securities  nor  have  such  authorities  passed  upon  or  endorsed  the  merits  of  the  offering  of  the
Securities.

l. Regulation M.  The  Holder  is  aware  that  the  anti-manipulation  rules  of  Regulation  M  under  the  Exchange Act  may  apply  to

sales of the Securities and other activities with respect to the Securities by the Holder.

m. Residency.  The  residency  of  the  Holder  (or,  in  the  case  of  a  partnership  or  corporation,  such  entity’s  principal  place  of

business) is correctly set forth on the signature page hereto.

9. Transfer of Warrant.

a. Warrant Register. The Company will maintain a register (the “Warrant Register”) containing the names and addresses of the
Holder. The Holder may change its address as shown on the Warrant Register by written notice to the Company requesting such
change. Any  notice  or  written  communication  required  or  permitted  to  be  given  to  the  Holder  may  be  delivered  or  given  by
mail to the Holder as shown on the Warrant Register and at the address shown on the Warrant Register. Until this Warrant is
transferred on the Warrant Register, the Company may treat the Holder as shown on the Warrant Register as the absolute owner
of this Warrant for all purposes, notwithstanding any notice to the contrary.

b. Warrant Agent .  The  Company  may,  by  written  notice  to  the  Holder,  appoint  an  agent  for  the  purpose  of  maintaining  the
Warrant  Register  referred  to  in  Section  9(a)  above,  issuing  the  Common  Stock  or  other  securities  then  issuable  upon  the
exercise of this Warrant, exchanging this Warrant, replacing this Warrant, or any or all of the foregoing. Thereafter, any such
registration, issuance, exchange, or replacement, as the case may be, shall be made at the office of such agent.

5

 
 
 
 
 
 
 
 
 
 
 
c. Compliance with Securities Laws.

i.

The Warrant and the Warrant Shares are characterized as “restricted securities” under the Securities Act inasmuch as they
are being acquired from the Company in a transaction not involving a public offering, and that under the Securities Act and
applicable regulations thereunder, such securities may be resold without registration under the Securities Act only in certain
limited  circumstances.  In  this  connection,  the  Holder  represents  that  it  is  familiar  with  the  Securities  and  Exchange
Commission (“SEC”) Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the
Securities Act. The Company is under no obligation to register any of the securities sold hereunder. No public market now
exists for this Warrant or the Warrant Shares and that it is uncertain whether a public market will ever exist for this Warrant
or the Warrant Shares.

ii. This  Warrant  and  all  certificates  for  the  Warrant  Shares  issued  upon  exercise  hereof  shall  be  stamped  or  imprinted  with

legends in substantially the following form (in addition to any legend required by state securities laws):

“THE  SECURITIES  REPRESENTED  HEREBY  HAVE  NOT  BEEN  REGISTERED  UNDER  THE
SECURITIES  ACT  OF  1933,  AS  AMENDED.  THE  SECURITIES  MAY  NOT  BE  SOLD  OR
OFFERED  FOR  SALE  IN  THE  ABSENCE  OF  (A)  AN  EFFECTIVE  REGISTRATION
STATEMENT FOR THE SECURITIES UNDER SUCH ACT, (B) A “NO ACTION” LETTER OF
THE  SECURITIES  AND  EXCHANGE  COMMISSION  WITH  RESPECT  TO  SUCH  SALE  OR
OFFER  OR 
(C)  SATISFACTORY  ASSURANCES  TO  THE  CORPORATION  THAT
REGISTRATION  UNDER  SUCH ACT  IS  NOT  REQUIRED  WITH  RESPECT  TO  SUCH  SALE
OR OFFER.

THE  SECURITIES  REPRESENTED  BY  THIS  CERTIFICATE  ARE  SUBJECT  TO
RESTRICTIONS  ON  TRANSFERABILITY AND  RESALE,  INCLUDING A  LOCK-UP  PERIOD
IN THE EVENT OF A PUBLIC OFFERING, AS SET FORTH IN THE WARRANT PURSUANT
TO  WHICH  THESE  SHARES  WERE  ISSUED, A  COPY  OF  WHICH  MAY  BE  OBTAINED AT
THE PRINCIPAL OFFICE OF THE COMPANY.”

d. Disposition of the Holder's Rights.

i.

Transferability. This Warrant shall not be transferred or assigned in whole or in part by Holder and any attempt by Holder to
transfer or assign any rights, duties or obligations that arise under this Warrant shall be void. Any transfer of the Warrant
Shares issuable upon exercise of this Warrant (the “Securities”) must be in compliance with all applicable securities laws.
The  Holder  agrees  not  to  make  any  sale,  assignment,  transfer, pledge  or  other  disposition  of  all  or  any  portion  of  the
Securities, or any beneficial interest therein, unless and until the transferee thereof has agreed in writing for the benefit of
the  Company  to  take  and  hold  such  Securities  subject  to,  and  to  be  bound  by,  the  terms  and  conditions  set  forth  in  this
Warrant to the same extent as if the transferee were the original Holder hereunder, and (A) such Holder shall have given
prior  written notice  to  the  Company  of  such  Holder’s  intention  to  make  such  disposition  and  shall have  furnished  the
Company with a detailed description of the manner and circumstances of the proposed disposition, (B) the transferee shall
have confirmed to the satisfaction of the Company in writing, substantially in the form of Exhibit A-1, that the Securities
are being acquired (i) solely for the transferee’s own account and not as a nominee for any other party, (ii) for investment
and (iii) not with a view toward distribution or resale, and shall have confirmed such other matters related thereto as may be
reasonably requested by the Company, and (C) such Holder shall have furnished the Company with an opinion of counsel,
reasonably satisfactory to the Company, to the effect that such disposition will not require registration of such Securities
under applicable securities laws.

6

 
 
 
 
 
 
 
 
 
10. Reservation of Stock. The Company covenants that during the term this Warrant is exercisable, the Company will reserve from its
authorized  and  unissued  Common  Stock  a  sufficient  number  of  shares  to  provide  for  the  issuance  of  Common  Stock  upon  the
exercise  of  this  Warrant  and,  from  time  to  time,  will  take  all  steps  necessary  to  amend  its Articles  of  Incorporation,  as  amended
and/or  amended  and  restated  from  time  to  time  (the  “Certificate”)  as  the  same  may  be  amended  from  time  to  time  to  provide
sufficient reserves of shares of Common Stock issuable upon exercise of the Warrant.

11. Amendments.

a. Any  term  of  this  Warrant  may  be  amended,  and  any  waiver  of  any  term  of  this  Warrant  may  be  granted,  with  the  written
consent of the Company and the holder of this Warrant. Any amendment or waiver effected in accordance with this Section 11
shall be binding upon each future holder of the Warrant and the Company, notwithstanding the fact that such future holder did
not consent to such amendment or waiver.

b. No waivers of or exceptions to any term, condition or provision of the Warrant, in any one or more instances, shall be deemed to

be, or construed as, a further or continuing waiver of any such term, condition or provision.

12. Adjustments. The Exercise Price and the number of shares purchasable hereunder are subject to adjustment from time to time as

follows:

a. Reclassification, etc. If the Company at any time while this Warrant, or any portion thereof, remains outstanding and unexpired
shall, by reclassification of securities or otherwise, change any of the securities as to which purchase rights under this Warrant
exist into the same or a different number of securities of any other class or classes, this Warrant shall thereafter represent the
right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the
securities  which  were  subject  to  the  purchase  rights  under  this  Warrant  immediately  prior  to  such  reclassification  or  other
change  and  the  Exercise  Price  therefor  shall  be  appropriately  adjusted,  all  subject  to  further  adjustment  as  provided  in  this
Section 12.

b. Split, Subdivision or Combination of Warrant Shares . If the Company at any time while this Warrant, or any portion thereof,
remains  outstanding  and  unexpired  shall  split,  subdivide  or  combine  the  securities  as  to  which  purchase  rights  under  this
Warrant  exist,  into  a  different  number  of  securities  of  the  same  class,  the  Exercise  Price  for  such  securities  shall  be
proportionately decreased in the case of a split or subdivision or proportionately increased in the case of a combination.

7

 
 
 
 
 
 
 
 
 
c. Merger  or  Reorganization.  If  at  any  time  there  shall  be  any  reorganization,  recapitalization,  merger  or  consolidation  (a
“Reorganization”)  involving  the  Company  (other  than  as  otherwise  provided  for  herein)  in  which  the  Company’s  equity
securities are converted into or exchanged for securities, cash or other property, then, as a part of such Reorganization, lawful
provision  shall  be  made  so  that  the  Holder  shall  thereafter  be  entitled  to  receive  upon  exercise  of  this  Warrant  the  kind  and
amount  of  securities,  cash  or  other  property  of  the  successor  corporation  resulting  from  such  Reorganization,  equivalent  in
value to that which a holder of the Warrant Shares deliverable upon exercise of this Warrant would have been entitled in such
Reorganization  if  the  right  to  purchase  the  Warrant  Shares  hereunder  had  been  exercised  immediately  prior  to  such
Reorganization.  In  any  such  case,  appropriate  adjustment  (as  determined  in  good  faith  by  the  Board  of  Directors  of  the
successor corporation) shall be made in the application of the provisions of this Warrant with respect to the rights and interests
of the Holder after such Reorganization to the end that the provisions of this Warrant shall be applicable after the event, as near
as reasonably may be, in relation to any shares or other securities deliverable after that event upon the exercise of this Warrant.

d. Certificate  as  to  Adjustments .  Upon  the  occurrence  of  each  adjustment  or  readjustment  pursuant  to  this  Section12,  the
Company  shall  promptly  compute  such  adjustment  or  readjustment  in  accordance  with  the  terms  hereof  and  furnish  to  the
Holder a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Company shall, upon the written request, at any time, of the Holder, furnish or cause to be furnished
to the Holder a like certificate setting forth: (i) such adjustments and readjustments; (ii) the Exercise Price at the time in effect;
and (iii) the number of shares and the amount, if any, of other property which at the time would be received upon the exercise
of the Warrant.

13. Miscellaneous.

a. Additional  Undertaking.  The  Holder  hereby  agrees  to  take  whatever  additional  action  and  execute  whatever  additional
documents  the  Company  may  deem  necessary  or  advisable  in  order  to  carry  out  or  effect  one  or  more  of  the  obligations  or
restrictions imposed on either the Holder or the shares of Common Stock issued upon exercise hereof pursuant to the provisions
of this Warrant.

b. Governing Law.  This  Warrant  shall  be  governed  by,  and  construed  in  accordance  with,  the  laws  of  the  State  of  New  York

without resort to its conflict-of-laws rules.

c.

Jurisdiction. The Holder and the Company irrevocably consents to the exclusive jurisdiction of, and venue in, the state courts in
the State of New York (or in the event of exclusive federal jurisdiction, the federal district courts in the State of New York), in
connection with any action based upon, arising out of or in connection with this Warrant or the matters contemplated herein,
and  agrees  that  process  may  be  served  upon  them  in  any  manner  authorized  by  the  law  of  the  State  of  New  York  for  such
persons.

d. Successors and Assigns. The provisions of this Warrant shall inure to the benefit of, and be binding upon, the Company and its
successors and assigns and upon the Holder and its successors, whether or not any such person shall have become a party to this
Warrant and have agreed in writing to join herein and be bound by the terms hereof.

e. Loss,  Theft,  Destruction  or  Mutilation  of  Warrant .  The  Company  covenants  that  upon  receipt  by  the  Company  of  evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the
Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case
of  the  Warrant,  shall  not  include  the  posting  of  any  bond),  and  upon  surrender  and  cancellation  of  such  Warrant  or  stock
certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of such Warrant or stock certificate.

8

 
 
 
 
 
 
 
 
 
 
f. Notices. All notices and other communications required or permitted hereunder shall be in writing and shall be sent by facsimile

or electronic mail or otherwise delivered by hand, messenger or courier service addressed:

i.

ii.

if  to  the  Holder,  to  the  Holder  at  the  Holder’s  address,  facsimile  number  or  electronic  mail  address  as  shown  in  the

Each such notice or other communication shall for all purposes of this Warrant be treated as effective or having been given (i)

Company’s  books  and  records  and  this  Warrant  or  any  notice  delivered  hereunder,  the  Company’s  books  and  records  will
control absent fraud or error.

g. Severability.  If  any  provision  of  this  Warrant  becomes  or  is  declared  by  a  court  of  competent  jurisdiction  to  be  illegal,
unenforceable or void, portions of such provision, or such provision in its entirety, to the extent necessary, shall be severed from
this Warrant, and such illegal, unenforceable or void provision shall be replaced with a valid and enforceable provision that will
achieve, to the extent possible, the same economic, business and other purposes of the illegal, unenforceable or void provision.
The balance of this Warrant shall be enforceable in accordance with its terms.

h. Rights and Obligations Survive Exercise of the Warrant. Except as otherwise provided herein, the rights and obligations of the

Company and the Holder under this Warrant shall survive exercise of this Warrant.

i.

MARKET STAND-OFF AGREEMENT

INVESTOR:

___________________________________

COMPANY:

XENETIC BIOSCIENCES, INC.

SECURITIES:

THE WARRANT ISSUED ON DECEMBER 31, 2014 (THE  “WARRANT”) AND THE SECURITIES ISSUED OR
ISSUABLE  UPON  EXERCISE  THEREOF  (INCLUDING  UPON  SUBSEQUENT  CONVERSION  OF  THOSE
SECURITIES)

___________________________________

In connection with the purchase or acquisition of the above-listed Securities, the undersigned Investor represents and warrants to,

and agrees with, the Company as follows:

1.

Investment Intent. The Investor understands that the Warrant and Warrant Shares (the “ Securities”)  are  “restricted  securities”  and
have not been and will not be registered under the Securities Act of 1933, as amended (the “Securities Act”) or any applicable state
securities law and is acquiring the Securities as principal for its own account and not with a view to, or for distributing or reselling
such Securities or any part thereof in violation of the Securities Act or any applicable state securities laws. The Investor is acquiring
the  Securities  hereunder  in  the  ordinary  course  of  its  business.  The  Investor  does  not  presently  have  any  agreement,  plan  or
understanding, directly or indirectly, with any person to distribute or effect any distribution of any of the Securities (or any securities
which are derivatives thereof) to or through any person or entity; the Investor is not a registered broker-dealer under Section 15 of
the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or an entity engaged in a business that would require it to be
so registered as a broker-dealer.

2.

Investor Status. At  the  time  the  Investor  was  offered  the  Securities,  it  was,  and  at  the  date  hereof  it  is,  either  (i)  an  “accredited
investor” as defined in Rule 501(a) under the Securities Act or (ii) not a “U.S. person” as defined in Rule 902 of Regulation S of the
Securities Act.

3. General  Solicitation.  The  Investor  is  not  acquiring  the  Securities  as  a  result  of  any  advertisement,  article,  notice  or  other
communication  regarding  the  Securities  published  in  any  newspaper,  magazine  or  similar  media  or  broadcast  over  television  or
radio or presented at any seminar or any other general advertisement.

4.

Investment  Experience.  The  Investor,  either  alone  or  together  with  its  representatives,  has  such  knowledge,  sophistication  and
experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in
the Securities, and has so evaluated the merits and risks of such investment. The Investor is able to bear the economic risk of an
investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

13

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
5. Access  to  Information.  The  Investor  acknowledges  that  it  has  been  afforded  (i)  the  opportunity  to  ask  such  questions  as  it  has

offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the Company and its
subsidiaries and their respective financial condition, results of operations, business, properties, management and prospects sufficient
to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or
can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the
investment.  The  Investor  has  sought  such  accounting,  legal  and  tax  advice  as  it  has  considered  necessary  to  make  an  informed
decision with respect to its acquisition of the Securities.

6. Brokers and Finders. No person will have, as a result of the transactions contemplated by the Warrant, any valid right, interest or
claim  against  or  upon  the  Company  or  the  Investor  for  any  commission,  fee  or  other  compensation  pursuant  to  any  agreement,
arrangement or understanding entered into by or on behalf of the Investor.

7.

Independent  Investment  Decision.  The  Investor  has  independently  evaluated  the  merits  of  its  decision  to  purchase  Securities
pursuant to the Warrant. The Investor understands that nothing in the Warrant or any other materials presented by or on behalf of the
Company  to  it  in  connection  with  the  purchase  of  the  Securities  constitutes  legal,  tax  or  investment  advice.  The  Investor  has
consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with
its purchase of the Securities.

8. Reliance on Exemptions. The Investor understands that the Securities being offered and sold to it in reliance on specific exemptions
from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the
truth  and  accuracy  of,  and  the  Investor’s  compliance  with,  the  representations,  warranties,  agreements,  acknowledgements  and
understandings of the Investor set forth herein in order to determine the availability of such exemptions and the eligibility of the
Investor to acquire the Securities.

9. No  Governmental  Review .  The  Investor  understands  that  no  United  States  federal  or  state  agency  or  any  other  government  or
governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of

Date of Issuance: December 31, 2014

This  certifies  that,  for  value  received,  Serum  Institute  of  India  Limited,  a  company  organized  under  the  laws  of  India,  or  its
registered  assigns  (the  “Holder”)  is  entitled,  subject  to  the  terms  set  forth  below,  to  purchase  from  Xenetic  Biosciences,  Inc.  (the
“Company”), a Nevada corporation, three million and two hundred thousand (3,200,000) shares of the Common Stock of the Company, par
value  $0.01  per  share,  (the  “Warrant  Shares”),  upon  surrender  hereof,  at  the  principal  office  of  the  Company  referred  to  below  and
simultaneous payment therefor in lawful money of the United States, at the Exercise Price as set forth in Section 2 below.

Subject to the terms and conditions set forth herein, this Warrant shall be exercisable with respect to the vested portion as set forth

in Section 1, in whole or in part, during the term commencing at December 31, 2016 and ending at December 30, 2019.

The  Holder  further  agrees  that,  in  addition  to  any  other  applicable  transfer  restrictions  in  the  applicable  securities  laws  and
agreements, without the Company’s prior written consent, the Holder shall not transfer more than [***]% of the total number of securities
of the Company held by it (calculated on an as converted to Common Stock basis) per rolling six months and more than [***]% of the
securities of the Company held by it (calculated on an as converted to Common Stock basis) per rolling calendar year.

1. Vesting. The exercisability of this Warrant shall vest as follows:

a. Following completion of Phase II(b) human clinical trials for SC and IV modes of administration of PSA-EPO, [***]% of the

Warrant Shares shall vest.

b. Following the initiation of Phase III human trials for SC and IV modes of administration of PSA-EPO, [***]% of the Warrant
Shares shall vest; provided, however, that the Holder shall take all reasonable steps to advance the Phase III human trials within
India, or in appropriate and approved alternative territories, including, but not limited to, Singapore, Malaysia and South Africa.

2. Exercise Price. The Exercise Price per share of Common Stock at which this Warrant may be exercised shall be equal to the higher
of $0.77 per share or the Fair Market Value on the date of issuance, as adjusted from time to time pursuant to Section 12 below (the
“Exercise Price”). For purposes of this Section 2, the “Fair Market Value” of one share of Common Stock on the date of issuance
shall have one of the following meanings:

1

 
 
 
 
 
 
 
 
 
 
 
 
 
 
a.

b.

c.

if  the  Common  Stock  is  listed  on  a  recognized  national  stock  exchange,  such  as  The  Nasdaq  Stock  Market  LLC,  the  Fair
Market Value shall be the Closing Price of the Common Stock on such recognized national stock exchange on the most recent
trading day prior to the date of issuance of this Warrant; for the purposes of this Warrant, “Closing Price” means the final price
at which one share of Common Stock is traded during any trading day;

if the Common Stock is not listed on a recognized national stock exchange but quoted in an over-the-counter market, the Fair
Market Value shall be deemed to be the volume weighted average price per share of Common Stock for the 20 trading days
ending on the day prior to the date of issuance of this Warrant;

if section (a) or (b) above is not applicable, the Fair Market Value shall equal the highest price per share which the Company
could obtain on the date of issuancefrom a willing buyer (not a current employee or director) for shares of Common Stock sold
by the Company, from authorized but unissued shares, as determined in good faith by the Company’s Board of Directors.

3. Exercise of Warrant.

a. Subject  to  the  terms  and  conditions  set  forth  herein,  the  purchase  rights  represented  by  this  Warrant  are  exercisable  by  the
Holder in whole or in part, from time to time, by the surrender of this Warrant and the Notice of Exercise attached hereto as
Exhibit A duly completed and executed on behalf of the Holder, at the office of the Company (or such other office or agency of
the Company as it may designate by notice in writing to the Holder at the address of the Holder appearing on the books of the
Company), upon payment in cash or by check acceptable to the Company of an amount equal to the aggregate Exercise Price of
the Warrant Shares being purchased.

b. This Warrant shall be deemed to have been exercised immediately prior to the close of business on the date of its surrender for
exercise as provided above, and the person entitled to receive the shares of Common Stock issuable upon such exercise shall be
treated  for  all  purposes  as  the  holder  of  record  of  such  shares  as  of  the  close  of  business  on  such  date.  As  promptly  as
practicable on or after such date, the Company shall issue and deliver to the person or persons entitled to receive the same a
certificate  or  certificates  for  the  number  of  shares  issuable  upon  such  exercise.  In  the  event  that  this  Warrant  is  exercised  in
part,  the  Company  will  execute  and  deliver  a  new  Warrant  of  like  tenor  exercisable  for  the  number  of  shares  for  which  this
Warrant may then be exercised.

4. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this
Warrant. In lieu of any fractional share to which the Holder would otherwise be entitled, the Company shall make a cash payment
equal to the Exercise Price multiplied by such fraction.

5. Replacement  of  Warrant .  On  receipt  of  evidence  reasonably  satisfactory  to  the  Company  of  the  loss,  theft,  destruction,  or
mutilation  of  this  Warrant  and,  in  the  case  of  loss,  theft,  or  destruction,  on  delivery  of  an  indemnity  agreement  reasonably
satisfactory in form and substance to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant, the
Company at its expense shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor and amount.

6. Rights of Stockholders. Until the Holder exercises this Warrant and the Company issues the Holder Warrant Shares purchasable
upon the exercise hereof, as provided herein, the Holder shall not be entitled to vote or receive dividends or be deemed the holder of
Common Stock or any other securities of the Company that may at any time be issuable on the exercise hereof for any purpose, nor
shall anything contained herein be construed to confer upon the Holder, as such, any of the rights of a shareholder of the Company
or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or
withhold  consent  or  assert  dissenter’s  rights  with  respect  to  any  corporate  action  (whether  upon  any  recapitalization,  issuance  of
stock,  reclassification  of  stock,  change  of  par  value,  or  change  of  stock  to  no  par  value,  consolidation,  merger,  conveyance,  or
otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise.

7. Market Stand-off. The Holder agrees that the Holder shall not sell or otherwise transfer, make any short sale of, grant any option
for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, of any shares of the
Company’s capital stock acquired through the exercise of this Warrant during the 180 day period following the commencement of
the  Company’s  public  offerings  (or  such  other  period  as  may  be  requested  by  the  Company  or  an  underwriter  to  accommodate
regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions).
The Holder further agrees that to the extent that the executive officers and directors of the Company are subject to a longer market
stand-off period, the Holder shall be subject to such longer market stand-off period as well. The Company may impose stop transfer
instructions and may stamp each certificate with a legend with respect to the shares subject to the foregoing restriction until the end
of such 180 day (or other) period. The Holder agrees to execute a market stand-off agreement with the underwriters in the offerings
in customary form consistent with the provisions of this section.

8. Representations  and  Warranties  of  the  Holder .  By  acceptance  of  this  Warrant,  the  Holder  represents  and  warrants  to  the

Company as follows:

a.                    Authority. The Holder represents that it has full power and authority to enter into this Warrant. This Warrant
constitutes the Holder’s valid and legally binding obligation, enforceable in accordance with its terms, except as may be limited by (i)
applicable bankruptcy, insolvency, reorganization, or similar laws relating to or affecting the enforcement  of  creditors’  rights  and  (ii)
laws relating to the availability of specific performance, injunctive relief or other equitable remedies.

b.                    No Conflicts. The execution, delivery and performance by the Holder of this Warrant and the consummation
by the Holder of the transactions contemplated hereby will not (i) result in a violation of the organizational documents of the Holder, (ii)
conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to
others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which the Holder
is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws)
applicable to the Holder, except in the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which would
not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of the Holder to perform its
obligations hereunder.

3

 
 
 
 
 
 
 
c.                   

Investment Intent. The Holder understands that this Warrant and the Warrant Shares (the “Securities”) are
“restricted securities” and have not been and will not be registered under the Securities Act of 1933, as amended (the “Securities Act”) or
any  applicable  state  securities  law  and  is  acquiring  the  Securities  as  principal  for  its  own  account  and  not  with  a  view  to,  or  for
distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable state securities laws. The
Holder is acquiring the Securities hereunder in the ordinary course of its business. The Holder does not presently have any agreement,
plan  or  understanding,  directly  or  indirectly,  with  any  person  to  distribute  or  effect  any  distribution  of  any  of  the  Securities  (or  any
securities which are derivatives thereof) to or through any person or entity; the Holder is not a registered broker-dealer under Section 15
of the Securities Exchange Act of 1934, as amended (the “ Exchange Act”), or an entity engaged in a business that would require it to be
so registered as a broker-dealer.

d.                   Investor Status. At the time the Holder was offered the Securities, it was, and at the date hereof it is, either (i)
an  “accredited  investor”  as  defined  in  Rule  501(a)  under  the  Securities Act  or  (ii)  not  a  “U.S.  person”  as  defined  in  Rule  902  of
Regulation S of the Securities Act.

e.                   General Solicitation. The Holder is not acquiring the Securities as a result of any advertisement, article, notice
or other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or
radio or presented at any seminar or any other general advertisement.

f.                    

Investment Experience. The Holder, either alone or together with its representatives, has such knowledge,
sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective
investment in the Securities, and has so evaluated the merits and risks of such investment. The Holder is able to bear the economic risk
of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

g.                   Access to Information. The Holder acknowledges that it has been afforded (i) the opportunity to ask such
questions  as  it  has  deemed  necessary  of,  and  to  receive  answers  from,  representatives  of  the  Company  concerning  the  terms  and
conditions of the offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the
Company  and  its  subsidiaries  and  their  respective  financial  condition,  results  of  operations,  business,  properties,  management  and
prospects  sufficient  to  enable  it  to  evaluate  its  investment;  and  (iii)  the  opportunity  to  obtain  such  additional  information  that  the
Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision
with respect to the investment. The Holder has sought such accounting, legal and tax advice as it has considered necessary to make an
informed decision with respect to its acquisition of the Securities.

h.                    Brokers and Finders. No person will have, as a result of the transactions contemplated by this Warrant, any
valid right, interest or claim against or upon the Company or the Holder for any commission, fee or other compensation pursuant to any
agreement, arrangement or understanding entered into by or on behalf of the Holder.

i.                    

Independent Investment Decision. The Holder has independently evaluated the merits of its decision to
purchase Securities pursuant to this Warrant. The Holder understands that nothing in this Warrant or any other materials presented by or
on behalf of the Company to it in connection with the purchase of the Securities constitutes legal, tax or investment advice. The Holder
has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with
its purchase of the Securities.

4

 
 
 
 
 
 
 
 
 
j.                    Reliance on Exemptions. The Holder understands that the Securities being offered and sold to it in reliance on
specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying
in  part  upon  the  truth  and  accuracy  of,  and  the  Holder’s  compliance  with,  the  representations,  warranties,  agreements,
acknowledgements and understandings of the Holder set forth herein in order to determine the availability of such exemptions and the
eligibility of the Holder to acquire the Securities.

k.                    No Governmental Review. The Holder understands that no United States federal or state agency or any other
government  or  governmental  agency  has  passed  on  or  made  any  recommendation  or  endorsement  of  the  Securities  or  the  fairness  or
suitability  of  the  investment  in  the  Securities  nor  have  such  authorities  passed  upon  or  endorsed  the  merits  of  the  offering  of  the
Securities.

l.                     Regulation M. The Holder is aware that the anti-manipulation rules of Regulation M under the Exchange Act

may apply to sales of the Securities and other activities with respect to the Securities by the Holder.

m.                  Residency. The residency of the Holder (or, in the case of a partnership or corporation, such entity’s principal

place of business) is correctly set forth on the signature page hereto.

9. Transfer of Warrant.

a. Warrant Register. The Company will maintain a register (the “Warrant Register”) containing the names and addresses of the
Holder. The Holder may change its address as shown on the Warrant Register by written notice to the Company requesting such
change. Any  notice  or  written  communication  required  or  permitted  to  be  given  to  the  Holder  may  be  delivered  or  given  by
mail to the Holder as shown on the Warrant Register and at the address shown on the Warrant Register. Until this Warrant is
transferred on the Warrant Register, the Company may treat the Holder as shown on the Warrant Register as the absolute owner
of this Warrant for all purposes, notwithstanding any notice to the contrary.

b. Warrant Agent .  The  Company  may,  by  written  notice  to  the  Holder,  appoint  an  agent  for  the  purpose  of  maintaining  the
Warrant  Register  referred  to  in  Section  9(a)  above,  issuing  the  Common  Stock  or  other  securities  then  issuable  upon  the
exercise of this Warrant, exchanging this Warrant, replacing this Warrant, or any or all of the foregoing. Thereafter, any such
registration, issuance, exchange, or replacement, as the case may be, shall be made at the office of such agent.

c. Compliance with Securities Laws.

i.

The Warrant and the Warrant Shares are characterized as “restricted securities”  under the Securities Act inasmuch as they
are being acquired from the Company in a transaction not involving a public offering, and that under the Securities Act and
applicable regulations thereunder, such securities may be resold without registration under the Securities Act only in certain
limited  circumstances.  In  this  connection,  the  Holder  represents  that it  is  familiar  with  the  Securities  and  Exchange
Commission (“SEC”) Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the
Securities Act. The Company is under no obligation to register any of the securities sold hereunder. No public market now
exists for this Warrant or the Warrant Shares and that it is uncertain whether a public market will ever exist for this Warrant
or the Warrant Shares.

5

 
 
 
 
 
 
 
 
 
 
 
ii. This  Warrant  and  all  certificates  for  the  Warrant  Shares  issued  upon  exercise  hereof  shall  be  stamped  or  imprinted  with

legends in substantially the following form (in addition to any legend required by state securities laws):

“THE  SECURITIES  REPRESENTED  HEREBY  HAVE  NOT  BEEN  REGISTERED  UNDER  THE
SECURITIES  ACT  OF  1933,  AS  AMENDED.  THE  SECURITIES  MAY  NOT  BE  SOLD  OR
OFFERED  FOR  SALE  IN  THE  ABSENCE  OF  (A)  AN  EFFECTIVE  REGISTRATION
STATEMENT FOR THE SECURITIES UNDER SUCH ACT, (B) A “NO ACTION” LETTER OF
THE  SECURITIES  AND  EXCHANGE  COMMISSION  WITH  RESPECT  TO  SUCH  SALE  OR
OFFER  OR 
(C)  SATISFACTORY  ASSURANCES  TO  THE  CORPORATION  THAT
REGISTRATION  UNDER  SUCH ACT  IS  NOT  REQUIRED  WITH  RESPECT  TO  SUCH  SALE
OR OFFER.

THE  SECURITIES  REPRESENTED  BY  THIS  CERTIFICATE  ARE  SUBJECT  TO
RESTRICTIONS  ON  TRANSFERABILITY AND  RESALE,  INCLUDING A  LOCK-UP  PERIOD
IN THE EVENT OF A PUBLIC OFFERING, AS SET FORTH IN THE WARRANT PURSUANT
TO  WHICH  THESE  SHARES  WERE  ISSUED, A  COPY  OF  WHICH  MAY  BE  OBTAINED AT
THE PRINCIPAL OFFICE OF THE COMPANY.”

d. Disposition of the Holder's Rights.

i.

Transferability. This Warrant shall not be transferred or assigned in whole or in part by Holder and any attempt by Holder to
transfer or assign any rights, duties or obligations that arise under this Warrant shall be void. Any transfer of the Warrant
Shares issuable upon exercise of this Warrant (the “Securities”) must be in compliance with all applicable securities laws.
The  Holder  agrees  not  to  make  any  sale,  assignment,  transfer,  pledge  or  other  disposition  of  all  or  any  portion  of  the
Securities, or any beneficial interest therein, unless and until the transferee thereof has agreed in writing for the benefit of
the  Company  to  take  and  hold  such  Securities  subject  to,  and  to  be  bound  by,  the  terms  and  conditions  set  forth  in  this
Warrant to the same extent as if the transferee were the original Holder hereunder, and (A) such Holder shall have given
prior  written  notice  to  the  Company  of  such  Holder’s  intention  to  make  such  disposition  and  shall  have  furnished  the
Company with a detailed description of the manner and circumstances of the proposed disposition, (B) the transferee shall
have confirmed to the satisfaction of the Company in writing, substantially in the form of Exhibit A-1, that the Securities
are being acquired (i) solely for the transferee’s own account and not as a nominee for any other party, (ii) for investment
and (iii) not with a view toward distribution or resale, and shall have confirmed such other matters related thereto as may be
reasonably requested by the Company, and (C) such Holder shall have furnished the Company with an opinion of counsel,
reasonably satisfactory to the Company, to the effect that such disposition will not require registration of such Securities
under applicable securities laws.

6

 
 
 
 
 
 
 
10. Reservation of Stock. The Company covenants that during the term this Warrant is exercisable, the Company will reserve from its
authorized  and  unissued  Common  Stock  a  sufficient  number  of  shares  to  provide  for  the  issuance  of  Common  Stock  upon  the
exercise  of  this  Warrant  and,  from  time  to  time,  will  take  all  steps  necessary  to  amend  its Articles  of  Incorporation,  as  amended
and/or  amended  and  restated  from  time  to  time  (the  “Certificate”)  as  the  same  may  be  amended  from  time  to  time  to  provide
sufficient reserves of shares of Common Stock issuable upon exercise of the Warrant.

11. Amendments.

a. Any  term  of  this  Warrant  may  be  amended,  and  any  waiver  of  any  term  of  this  Warrant  may  be  granted,  with  the  written
consent of the Company and the holder of this Warrant. Any amendment or waiver effected in accordance with this Section 11
shall be binding upon each future holder of the Warrant and the Company, notwithstanding the fact that such future holder did
not consent to such amendment or waiver.

b. No waivers of or exceptions to any term, condition or provision of the Warrant, in any one or more instances, shall be deemed to

be, or construed as, a further or continuing waiver of any such term, condition or provision.

12. Adjustments. The Exercise Price and the number of shares purchasable hereunder are subject to adjustment from time to time as

follows:

a. Reclassification, etc. If the Company at any time while this Warrant, or any portion thereof, remains outstanding and unexpired
shall, by reclassification of securities or otherwise, change any of the securities as to which purchase rights under this Warrant
exist into the same or a different number of securities of any other class or classes, this Warrant shall thereafter represent the
right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the
securities  which  were  subject  to  the  purchase  rights  under  this  Warrant  immediately  prior  to  such  reclassification  or  other
change  and  the  Exercise  Price  therefor  shall  be  appropriately  adjusted,  all  subject  to  further  adjustment  as  provided  in  this
Section 12.

b. Split, Subdivision or Combination of Warrant Shares . If the Company at any time while this Warrant, or any portion thereof,
remains  outstanding  and  unexpired  shall  split,  subdivide  or  combine  the  securities  as  to  which  purchase  rights  under  this
Warrant  exist,  into  a  different  number  of  securities  of  the  same  class,  the  Exercise  Price  for  such  securities  shall  be
proportionately decreased in the case of a split or subdivision or proportionately increased in the case of a combination.

c. Merger  or  Reorganization.  If  at  any  time  there  shall  be  any  reorganization, recapitalization,  merger  or  consolidation  (a
“Reorganization”)  involving  the  Company  (other  than  as otherwise  provided  for  herein)  in  which  the  Company’s  equity
securities are converted into or exchanged for securities, cash or other property, then, as a part of such Reorganization, lawful
provision  shall  be  made  so  that  the  Holder  shall thereafter  be  entitled  to  receive  upon  exercise  of  this  Warrant  the  kind  and
amount  of  securities,  cash  or  other  property  of the  successor  corporation  resulting  from  such  Reorganization,  equivalent  in
value to that which a holder of the Warrant Shares deliverable upon exercise of this Warrant would have been entitled in such
Reorganization  if  the  right  to  purchase  the Warrant  Shares  hereunder  had  been  exercised  immediately  prior  to  such
Reorganization.  In  any  such  case,  appropriate  adjustment  (as  determined  in  good  faith  by  the  Board  of  Directors  of  the
successor corporation) shall be made in the application of the provisions of this Warrant with respect to the rights and interests
of the Holder after such Reorganization to the end that the provisions of this Warrant shall be applicable after the event, as near
as reasonably may be, in relation to any shares or other securities deliverable after that event upon the exercise of this Warrant.

7

 
 
 
 
 
 
 
 
 
 
d. Certificate  as  to  Adjustments .  Upon  the  occurrence  of  each  adjustment  or  readjustment  pursuant  to  this  Section  12,  the
Company  shall  promptly  compute  such  adjustment  or  readjustment  in  accordance  with  the  terms  hereof  and  furnish  to  the
Holder a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Company shall, upon the written request, at any time, of the Holder, furnish or cause to be furnished
to the Holder a like certificate setting forth: (i) such adjustments and readjustments; (ii) the Exercise Price at the time in effect;
and (iii) the number of shares and the amount, if any, of other property which at the time would be received upon the exercise
of the Warrant.

13. Miscellaneous.

a. Additional  Undertaking.  The  Holder  hereby  agrees  to  take  whatever  additional  action  and  execute  whatever  additional
documents  the  Company  may  deem  necessary  or  advisable  in  order  to  carry  out  or  effect  one  or  more  of  the  obligations  or
restrictions imposed on either the Holder or the shares of Common Stock issued upon exercise hereof pursuant to the provisions
of this Warrant.

b. Governing Law.  This  Warrant  shall  be  governed  by,  and  construed  in  accordance  with,  the  laws  of  the  State  of  New  York

without resort to its conflict-of-laws rules.

c.

Jurisdiction. The Holder and the Company irrevocably consents to the exclusive jurisdiction of, and venue in, the state courts in
the State of New York (or in the event of exclusive federal jurisdiction, the federal district courts in the State of New York), in
connection with any action based upon, arising out of or in connection with this Warrant or the matters contemplated herein,
and  agrees  that  process  may  be  served  upon  them  in  any  manner  authorized  by  the  law  of  the  State  of  New  York  for  such
persons.

d. Successors and Assigns. The provisions of this Warrant shall inure to the benefit of, and be binding upon, the Company and its
successors and assigns and upon the Holder and its successors, whether or not any such person shall have become a party to this
Warrant and have agreed in writing to join herein and be bound by the terms hereof.

e. Loss,  Theft,  Destruction  or  Mutilation  of  Warrant .  The  Company  covenants  that  upon  receipt  by  the  Company  of  evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the
Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case
of  the  Warrant,  shall  not  include  the  posting  of  any  bond),  and  upon  surrender  and  cancellation  of  such  Warrant  or  stock
certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such

INVESTMENT REPRESENTATION STATEMENT
AND
MARKET STAND-OFF AGREEMENT

INVESTOR:

___________________________________

COMPANY:

XENETIC BIOSCIENCES, INC.

SECURITIES:

THE WARRANT ISSUED ON DECEMBER 31, 2014 (THE  “WARRANT”) AND THE SECURITIES ISSUED OR
ISSUABLE  UPON  EXERCISE  THEREOF  (INCLUDING  UPON  SUBSEQUENT  CONVERSION  OF  THOSE
SECURITIES)

DATE:

___________________________________

In connection with the purchase or acquisition of the above-listed Securities, the undersigned Investor represents and warrants to,

and agrees with, the Company as follows:

1.

Investment Intent. The Investor understands that the Warrant and Warrant Shares (the “ Securities”)  are  “restricted  securities”  and
have not been and will not be registered under the Securities Act of 1933, as amended (the “Securities Act”) or any applicable state
securities law and is acquiring the Securities as principal for its own account and not with a view to, or for distributing or reselling
such Securities or any part thereof in violation of the Securities Act or any applicable state securities laws. The Investor is acquiring
the  Securities  hereunder  in  the  ordinary  course  of  its  business.  The  Investor  does  not  presently  have  any  agreement,  plan  or
understanding, directly or indirectly, with any person to distribute or effect any distribution of any of the Securities (or any securities
which are derivatives thereof) to or through any person or entity; the Investor is not a registered broker-dealer under Section 15 of
the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or an entity engaged in a business that would require it to be
so registered as a broker-dealer.

2.

Investor Status. At  the  time  the  Investor  was  offered  the  Securities,  it  was,  and  at  the  date  hereof  it  is,  either  (i)  an  “accredited
investor” as defined in Rule 501(a) under the Securities Act or (ii) not a “U.S. person” as defined in Rule 902 of Regulation S of the
Securities Act.

3. General  Solicitation.  The  Investor  is  not  acquiring  the  Securities  as  a  result  of  any  advertisement,  article,  notice  or  other
communication  regarding  the  Securities  published  in  any  newspaper,  magazine  or  similar  media  or  broadcast  over  television  or
radio or presented at any seminar or any other general advertisement.

4.

Investment  Experience.  The  Investor,  either  alone  or  together  with  its  representatives,  has  such  knowledge,  sophistication  and
experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in
the Securities, and has so evaluated the merits and risks of such investment. The Investor is able to bear the economic risk of an
investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

5. Access  to  Information.  The  Investor  acknowledges  that  it  has  been  afforded  (i)  the  opportunity  to  ask  such  questions  as  it  has
deemed  necessary  of,  and  to  receive  answers  from,  representatives  of  the  Company  concerning  the  terms  and  conditions  of  the
offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the Company and its
subsidiaries and their respective financial condition, results of operations, business, properties, management and prospects sufficient
to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or
can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the
investment.  The  Investor  has  sought  such  accounting,  legal  and  tax  advice  as  it  has  considered  necessary  to  make  an  informed
decision with respect to its acquisition of the Securities.

13

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
6. Brokers and Finders. No person will have, as a result of the transactions contemplated by the Warrant, any valid right, interest or
claim  against  or  upon  the  Company  or  the  Investor  for  any  commission,  fee  or  other  compensation  pursuant  to  any  agreement,
arrangement or understanding entered into by or on behalf of the Investor.

7.

Independent  Investment  Decision.  The  Investor  has  independently  evaluated  the  merits  of  its  decision  to  purchase  Securities
pursuant to the Warrant. The Investor understands that nothing in the Warrant or any other materials presented by or on behalf of the
Company  to  it  in  connection  with  the  purchase  of  the  Securities  constitutes  legal,  tax  or  investment  advice.  The  Investor  has
consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with
its purchase of the Securities.

8. Reliance on Exemptions. The Investor understands that the Securities being offered and sold to it in reliance on specific exemptions
from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the
truth  and  accuracy  of,  and  the  Investor’s  compliance  with,  the  representations,  warranties,  agreements,  acknowledgements  and
understandings of the Investor set forth herein in order to determine the availability of such exemptions and the eligibility of the
Investor to acquire the Securities.

9. No  Governmental  Review .  The  Investor  understands  that  no  United  States  federal  or  state  agency  or  any  other  government  or
governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of
the investment in the Securities nor have such authorities passed upon or endorsed the merits of the offering of the Securities.

10. Regulation M. The Investor is aware that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of

the Securities and other activities with respect to the Securities by the Investor.

11. Residency. The residency of the Investor (or, in the case of a partnership or corporation, such entity’s principal place of business) is

correctly set forth on the signature page hereto.

12. Market Stand-off. The Investor agrees that the Investor shall not sell or otherwise transfer, make any short sale of, grant any option
for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, of any shares of the
Company’s capital stock acquired through the exercise of the Warrant during the 180 day period following the commencement of
the  Company’s  public  offerings  (or  such  other  period  as  may  be  requested  by  the  Company  or  an  underwriter  to  accommodate
regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions).
The Investor further agrees that to the extent that the executive officers and directors of the Company are subject to a longer market
stand-off  period,  the  Investor  shall  be  subject  to  such  longer  market  stand-off  period  as  well.  The  Company  may  impose  stop
transfer instructions and may stamp each certificate with a legend with respect to the shares subject to the foregoing restriction until
the end of such 180 day (or other) period. The Investor agrees to execute a market stand-off agreement with the underwriters in the
offerings in customary form consistent with the provisions of this section.

EXHIBIT 10.4

WARRANT TO PURCHASE COMMON STOCK

OF

XENETIC BIOSCIENCES, INC.

Void after December 30, 2019

Date of Issuance: December 31, 2014

This certifies that, for value received, Firdaus Jal Dastoor, or his registered assigns (the “Holder”) is entitled, subject to the terms
set forth below, to purchase from Xenetic Biosciences, Inc. (the “ Company”), a Nevada corporation, one million and six hundred thousand
(1,600,000) shares of the Common Stock of the Company, par value $0.01 per share, (the “ Warrant Shares”), upon surrender hereof, at the
principal office of the Company referred to below and simultaneous payment therefor in lawful money of the United States, at the Exercise
Price as set forth in Section 1 below.

Subject  to  the  terms  and  conditions  set  forth  herein,  this  Warrant  shall  be  exercisable,  in  whole  or  in  part,  during  the  term

commencing at December 31, 2016 and ending at December 30, 2019.

1. Exercise Price. The Exercise Price per share of Common Stock at which this Warrant may be exercised shall be equal to the higher
of $0.77 per share or the Fair Market Value on the date of issuance, as adjusted from time to time pursuant to Section 11 below (the
“Exercise Price”). For purposes of this Section 1, the “Fair Market Value” of one share of Common Stock on the date of issuance
shall have one of the following meanings:

a.

b.

c.

if  the  Common  Stock  is  listed  on  a  recognized  national  stock  exchange,  such  as  The  Nasdaq  Stock  Market  LLC,  the  Fair
Market Value shall be the Closing Price of the Common Stock on such recognized national stock exchange on the most recent
trading day prior to the date of issuance of this Warrant; for the purposes of this Warrant, “Closing Price” means the final price
at which one share of Common Stock is traded during any trading day;

if the Common Stock is not listed on a recognized national stock exchange but quoted in an over-the-counter market, the Fair
Market Value shall be deemed to be the volume weighted average price per share of Common Stock for the 20 trading days
ending on the day prior to the date of issuance of this Warrant;

if section (a) or (b) above is not applicable, the Fair Market Value shall equal the highest price per share which the Company
could obtain on the date of issuance from a willing buyer (not a current employee or director) for shares of Common Stock sold
by the Company, from authorized but unissued shares, as determined in good faith by the Company’s Board of Directors.

1

 
 
 
 
 
 
 
 
 
 
 
 
 
2. Exercise of Warrant.

a. Subject  to  the  terms  and  conditions  set  forth  herein,  the  purchase  rights  represented  by  this  Warrant  are  exercisable  by  the
Holder in whole or in part, from time to time, by the surrender of this Warrant and the Notice of Exercise attached hereto as
Exhibit A duly completed and executed on behalf of the Holder, at the office of the Company (or such other office or agency of
the Company as it may designate by notice in writing to the Holder at the address of the Holder appearing on the books of the
Company), upon payment in cash or by check acceptable to the Company of an amount equal to the aggregate Exercise Price of
the Warrant Shares being purchased.

b. This Warrant shall be deemed to have been exercised immediately prior to the close of business on the date of its surrender for
exercise as provided above, and the person entitled to receive the shares of Common Stock issuable upon such exercise shall be
treated  for  all  purposes  as  the  holder  of  record  of  such  shares  as  of  the  close  of  business  on  such  date.  As  promptly  as
practicable on or after such date, the Company shall issue and deliver to the person or persons entitled to receive the same a
certificate  or  certificates  for  the  number  of  shares  issuable  upon  such  exercise.  In  the  event  that  this  Warrant  is  exercised  in
part,  the  Company  will  execute  and  deliver  a  new  Warrant  of  like  tenor  exercisable  for  the  number  of  shares  for  which  this
Warrant may then be exercised.

3. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this
Warrant. In lieu of any fractional share to which the Holder would otherwise be entitled, the Company shall make a cash payment
equal to the Exercise Price multiplied by such fraction.

4. Replacement  of  Warrant .  On  receipt  of  evidence  reasonably  satisfactory  to  the  Company  of  the  loss,  theft,  destruction,  or
mutilation  of  this  Warrant  and,  in  the  case  of  loss,  theft,  or  destruction,  on  delivery  of  an  indemnity  agreement  reasonably
satisfactory in form and substance to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant, the
Company at its expense shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor and amount.

5. Rights of Stockholders. Until the Holder exercises this Warrant and the Company issues the Holder Warrant Shares purchasable
upon the exercise hereof, as provided herein, the Holder shall not be entitled to vote or receive dividends or be deemed the holder of
Common Stock or any other securities of the Company that may at any time be issuable on the exercise hereof for any purpose, nor
shall anything contained herein be construed to confer upon the Holder, as such, any of the rights of a shareholder of the Company
or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or
withhold  consent  or  assert  dissenter’s  rights  with  respect  to  any  corporate  action  (whether  upon  any  recapitalization,  issuance  of
stock,  reclassification  of  stock,  change  of  par  value,  or  change  of  stock  to  no  par  value,  consolidation,  merger,  conveyance,  or
otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise.

6. Market Stand-off. The Holder agrees that the Holder shall not sell or otherwise transfer, make any short sale of, grant any option
for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, of any shares of the
Company’s capital stock acquired through the exercise of this Warrant during the 180 day period following the commencement of
the  Company’s  public  offerings  (or  such  other  period  as  may  be  requested  by  the  Company  or  an  underwriter  to  accommodate
regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions).
The Holder further agrees that to the extent that the executive officers and directors of the Company are subject to a longer market
stand-off period, the Holder shall be subject to such longer market stand-off period as well. The Company may impose stop transfer
instructions and may stamp each certificate with a legend with respect to the shares subject to the foregoing restriction until the end
of such 180 day (or other) period. The Holder agrees to execute a market stand-off agreement with the underwriters in the offerings
in customary form consistent with the provisions of this section.

7. Representations and Warranties of the Holder . By acceptance of this Warrant, the Holder represents and warrants to the

Company as follows:

a.                    Authority. The Holder represents that it has full power and authority to enter into this Warrant. This Warrant

applicable bankruptcy, insolvency, reorganization, or similar laws relating to or affecting the enforcement  of  creditors’  rights  and  (ii)
laws relating to the availability of specific performance, injunctive relief or other equitable remedies.

b.                    No Conflicts. The execution, delivery and performance by the Holder of this Warrant and the consummation
by the Holder of the transactions contemplated hereby will not (i) result in a violation of the organizational documents of the Holder, (ii)
conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to
others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which the Holder
is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws)
applicable to the Holder, except in the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which would
not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of the Holder to perform its
obligations hereunder.

c.                   

Investment Intent. The Holder understands that this Warrant and the Warrant Shares (the “Securities”) are

distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable state securities laws. The
Holder is acquiring the Securities hereunder in the ordinary course of its business. The Holder does not presently have any agreement,
plan  or  understanding,  directly  or  indirectly,  with  any  person  to  distribute  or  effect  any  distribution  of  any  of  the  Securities  (or  any
securities which are derivatives thereof) to or through any person or entity; the Holder is not a registered broker-dealer under Section 15
of the Securities Exchange Act of 1934, as amended (the “ Exchange Act”), or an entity engaged in a business that would require it to be
so registered as a broker-dealer.

d.                   Investor Status. At the time the Holder was offered the Securities, it was, and at the date hereof it is, either (i)
an  “accredited  investor”  as  defined  in  Rule  501(a)  under  the  Securities Act  or  (ii)  not  a  “U.S.  person”  as  defined  in  Rule  902  of
Regulation S of the Securities Act.

3

 
 
 
 
 
 
 
 
e.                   General Solicitation. The Holder is not acquiring the Securities as a result of any advertisement, article, notice
or other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or
radio or presented at any seminar or any other general advertisement.

f.                    

Investment Experience. The Holder, either alone or together with its representatives, has such knowledge,
sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective
investment in the Securities, and has so evaluated the merits and risks of such investment. The Holder is able to bear the economic risk
of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

g.                    Access to Information. The Holder acknowledges that it has been afforded (i) the opportunity to ask such
questions  as  it  has  deemed  necessary  of,  and  to  receive  answers  from,  representatives  of  the  Company  concerning  the  terms  and
conditions of the offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the
Company  and  its  subsidiaries  and  their  respective  financial  condition,  results  of  operations,  business,  properties,  management  and
prospects  sufficient  to  enable  it  to  evaluate  its  investment;  and  (iii)  the  opportunity  to  obtain  such  additional  information  that  the
Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision
with respect to the investment. The Holder has sought such accounting, legal and tax advice as it has considered necessary to make an
informed decision with respect to its acquisition of the Securities.

h.                    Brokers and Finders. No person will have, as a result of the transactions contemplated by this Warrant, any
valid right, interest or claim against or upon the Company or the Holder for any commission, fee or other compensation pursuant to any
agreement, arrangement or understanding entered into by or on behalf of the Holder.

i.                    

Independent Investment Decision. The Holder has independently evaluated the merits of its decision to
purchase Securities pursuant to this Warrant. The Holder understands that nothing in this Warrant or any other materials presented by or
on behalf of the Company to it in connection with the purchase of the Securities constitutes legal, tax or investment advice. The Holder
has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with
its purchase of the Securities.

j.                    Reliance on Exemptions. The Holder understands that the Securities being offered and sold to it in reliance on
specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying
in  part  upon  the  truth  and  accuracy  of,  and  the  Holder’s  compliance  with,  the  representations,  warranties,  agreements,
acknowledgements and understandings of the Holder set forth herein in order to determine the availability of such exemptions and the
eligibility of the Holder to acquire the Securities.

k.                    No Governmental Review. The Holder understands that no United States federal or state agency or any other
government  or  governmental  agency  has  passed  on  or  made  any  recommendation  or  endorsement  of  the  Securities  or  the  fairness  or
suitability  of  the  investment  in  the  Securities  nor  have  such  authorities  passed  upon  or  endorsed  the  merits  of  the  offering  of  the
Securities.

l.                     Regulation M. The Holder is aware that the anti-manipulation rules of Regulation M under the Exchange Act

may apply to sales of the Securities and other activities with respect to the Securities by the Holder.

8. Transfer of Warrant.

a. Warrant Register. The Company will maintain a register (the “Warrant Register”) containing the names and addresses of the
Holder. The Holder may change its address as shown on the Warrant Register by written notice to the Company requesting such
change. Any  notice  or  written  communication  required  or  permitted  to  be  given  to  the  Holder  may  be  delivered  or  given  by
mail to the Holder as shown on the Warrant Register and at the address shown on the Warrant Register. Until this Warrant is
transferred on the Warrant Register, the Company may treat the Holder as shown on the Warrant Register as the absolute owner
of this Warrant for all purposes, notwithstanding any notice to the contrary.

b. Warrant Agent .  The  Company  may,  by  written  notice  to  the  Holder,  appoint  an  agent  for  the  purpose  of  maintaining  the
Warrant  Register  referred  to  in  Section  8(a)  above,  issuing  the  Common  Stock  or  other  securities  then  issuable  upon  the
exercise of this Warrant, exchanging this Warrant, replacing this Warrant, or any or all of the foregoing. Thereafter, any such
registration, issuance, exchange, or replacement, as the case may be, shall be made at the office of such agent.

c. Compliance with Securities Laws.

i.

The Warrant and the Warrant Shares are characterized as “restricted securities” under the Securities Act inasmuch as they
are being acquired from the Company in a transaction not involving a public offering, and that under the Securities Act and
applicable regulations thereunder, such securities may be resold without registration under the Securities Act only in certain
limited  circumstances.  In  this  connection,  the  Holder  represents  that  it  is  familiar  with  the  Securities  and  Exchange
Commission (“SEC”) Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the
Securities Act. The Company is under no obligation to register any of the securities sold hereunder. No public market now
exists for this Warrant or the Warrant Shares and that it is uncertain whether a public market will ever exist for this Warrant
or the Warrant Shares.

ii. This  Warrant  and  all  certificates  for  the  Warrant  Shares  issued  upon  exercise  hereof  shall  be  stamped  or  imprinted  with

legends in substantially the following form (in addition to any legend required by state securities laws):

“THE  SECURITIES  REPRESENTED  HEREBY  HAVE  NOT  BEEN  REGISTERED  UNDER  THE
SECURITIES  ACT  OF  1933,  AS  AMENDED.  THE  SECURITIES  MAY  NOT  BE  SOLD  OR
OFFERED  FOR  SALE  IN  THE  ABSENCE  OF  (A)  AN  EFFECTIVE  REGISTRATION
STATEMENT FOR THE SECURITIES UNDER SUCH ACT, (B) A “NO ACTION” LETTER OF
THE  SECURITIES  AND  EXCHANGE  COMMISSION  WITH  RESPECT  TO  SUCH  SALE  OR
OFFER  OR 
(C)  SATISFACTORY  ASSURANCES  TO  THE  CORPORATION  THAT
REGISTRATION  UNDER  SUCH ACT  IS  NOT  REQUIRED  WITH  RESPECT  TO  SUCH  SALE
OR OFFER.

THE  SECURITIES  REPRESENTED  BY  THIS  CERTIFICATE  ARE  SUBJECT  TO
RESTRICTIONS  ON  TRANSFERABILITY AND  RESALE,  INCLUDING A  LOCK-UP  PERIOD
IN THE EVENT OF A PUBLIC OFFERING, AS SET FORTH IN THE WARRANT PURSUANT
TO  WHICH  THESE  SHARES  WERE  ISSUED, A  COPY  OF  WHICH  MAY  BE  OBTAINED AT
THE PRINCIPAL OFFICE OF THE COMPANY.”

d. Disposition of the Holder's Rights.

i.

Transferability. This Warrant shall not be transferred or assigned in whole or in part by Holder and any attempt by Holder to
transfer or assign any rights, duties or obligations that arise under this Warrant shall be void. Any transfer of the Warrant
Shares issuable upon exercise of this Warrant (the “Securities”) must be in compliance with all applicable securities laws.
The  Holder  agrees  not  to  make  any  sale,  assignment,  transfer,  pledge  or  other  disposition  of  all  or  any  portion  of  the
Securities, or any beneficial interest therein, unless and until the transferee thereof has agreed in writing for the benefit of
the  Company  to  take  and  hold  such  Securities  subject  to,  and  to  be  bound  by,  the  terms  and  conditions  set  forth  in  this
Warrant to the same extent as if the transferee were the original Holder hereunder, and (A) such Holder shall have given
prior  written  notice  to  the  Company  of  such  Holder’s  intention  to  make  such  disposition  and  shall  have  furnished  the
Company with a detailed description of the manner and circumstances of the proposed disposition, (B) the transferee shall
have confirmed to the satisfaction of the Company in writing, substantially in the form of Exhibit A-1, that the Securities
are being acquired (i) solely for the transferee’s own account and not as a nominee for any other party, (ii) for investment
and (iii) not with a view toward distribution or resale, and shall have confirmed such other matters related thereto as may be
reasonably requested by the Company, and (C) such Holder shall have furnished the Company with an opinion of counsel,
reasonably satisfactory to the Company, to the effect that such disposition will not require registration of such Securities
under applicable securities laws.

9. Reservation of Stock. The Company covenants that during the term this Warrant is exercisable, the Company will reserve from its
authorized  and  unissued  Common  Stock  a  sufficient  number  of  shares  to  provide  for  the  issuance  of  Common  Stock  upon  the
exercise  of  this  Warrant  and,  from  time  to  time,  will  take  all  steps  necessary  to  amend  its Articles  of  Incorporation,  as  amended
and/or  amended  and  restated  from  time  to  time  (the  “Certificate”)  as  the  same  may  be  amended  from  time  to  time  to  provide
sufficient reserves of shares of Common Stock issuable upon exercise of the Warrant.

10. Amendments.

a. Any  term  of  this  Warrant  may  be  amended,  and  any  waiver  of  any  term  of  this  Warrant  may  be  granted,  with  the  written
consent of the Company and the holder of this Warrant. Any amendment or waiver effected in accordance with this Section 10
shall be binding upon each future holder of the Warrant and the Company, notwithstanding the fact that such future holder did
not consent to such amendment or waiver.

b. No waivers of or exceptions to any term, condition or provision of the Warrant, in any one or more instances, shall be deemed to

be, or construed as, a further or continuing waiver of any such term, condition or provision.

6

 
 
 
 
 
 
 
 
11. Adjustments. The Exercise Price and the number of shares purchasable hereunder are subject to adjustment from time to time as

follows:

a. Reclassification, etc. If the Company at any time while this Warrant, or any portion thereof, remains outstanding and unexpired
shall, by reclassification of securities or otherwise, change any of the securities as to which purchase rights under this Warrant
exist into the same or a different number of securities of any other class or classes, this Warrant shall thereafter represent the
right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the
securities  which  were  subject  to  the  purchase  rights  under  this  Warrant  immediately  prior  to  such  reclassification  or  other
change  and  the  Exercise  Price  therefor  shall  be  appropriately  adjusted,  all  subject  to  further  adjustment  as  provided  in  this
Section 11.

b. Split, Subdivision or Combination of Warrant Shares . If the Company at any time while this Warrant, or any portion thereof,
remains  outstanding  and  unexpired  shall  split,  subdivide  or  combine  the  securities  as  to  which  purchase  rights  under  this
Warrant  exist,  into  a  different  number  of  securities  of  the  same  class,  the  Exercise  Price  for  such  securities  shall  be
proportionately decreased in the case of a split or subdivision or proportionately increased in the case of a combination.

c. Merger  or  Reorganization.  If  at  any  time  there  shall  be  any  reorganization,  recapitalization,  merger  or  consolidation  (a
“Reorganization”)  involving  the  Company  (other  than  as  otherwise  provided  for  herein)  in  which  the  Company’s  equity
securities are converted into or exchanged for securities, cash or other property, then, as a part of such Reorganization, lawful
provision  shall  be  made  so  that  the  Holder  shall  thereafter  be  entitled  to  receive  upon  exercise  of  this  Warrant  the  kind  and
amount  of  securities,  cash  or  other  property  of  the  successor  corporation  resulting  from  such  Reorganization,  equivalent  in
value to that which a holder of the Warrant Shares deliverable upon exercise of this Warrant would have been entitled in such
Reorganization  if  the  right  to  purchase  the  Warrant  Shares  hereunder  had  been  exercised  immediately  prior  to  such
Reorganization.  In  any  such  case,  appropriate  adjustment  (as  determined  in  good  faith  by  the  Board  of  Directors  of  the
successor corporation) shall be made in the application of the provisions of this Warrant with respect to the rights and interests
of the Holder after such Reorganization to the end that the provisions of this Warrant shall be applicable after the event, as near
as reasonably may be, in relation to any shares or other securities deliverable after that event upon the exercise of this Warrant.

d. Certificate  as  to  Adjustments .  Upon  the  occurrence  of  each  adjustment  or  readjustment  pursuant  to  this  Section  11,  the
Company  shall  promptly  compute  such  adjustment  or  readjustment  in  accordance  with  the  terms  hereof  and  furnish  to  the
Holder a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Company shall, upon the written request, at any time, of the Holder, furnish or cause to be furnished
to the Holder a like certificate setting forth: (i) such adjustments and readjustments; (ii) the Exercise Price at the time in effect;
and (iii) the number of shares and the amount, if any, of other property which at the time would be received upon the exercise
of the Warrant.

7

 
 
 
 
 
 
 
12. Miscellaneous.

a. Additional  Undertaking.  The  Holder  hereby  agrees  to  take  whatever  additional  action  and  execute  whatever  additional
documents  the  Company  may  deem  necessary  or  advisable  in  order  to  carry  out  or  effect  one  or  more  of  the  obligations  or
restrictions imposed on either the Holder or the shares of Common Stock issued upon exercise hereof pursuant to the provisions
of this Warrant.

the State of New York (or in the event of exclusive federal jurisdiction, the federal district courts in the State of New York), in
connection with any action based upon, arising out of or in connection with this Warrant or the matters contemplated herein,
and  agrees  that  process  may  be  served  upon  them  in  any  manner  authorized  by  the  law  of  the  State  of  New  York  for  such
persons.

d. Successors and Assigns. The provisions of this Warrant shall inure to the benefit of, and be binding upon, the Company and its
successors and assigns and upon the Holder and its successors, whether or not any such person shall have become a party to this
Warrant and have agreed in writing to join herein and be bound by the terms hereof.

e. Loss,  Theft,  Destruction  or  Mutilation  of  Warrant .  The  Company  covenants  that  upon  receipt  by  the  Company  of  evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the
Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case
of  the  Warrant,  shall  not  include  the  posting  of  any  bond),  and  upon  surrender  and  cancellation  of  such  Warrant  or  stock
certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of such Warrant or stock certificate.

f. Notices. All notices and other communications required or permitted hereunder shall be in writing and shall be sent by facsimile

or electronic mail or otherwise delivered by hand, messenger or courier service addressed:

i.

ii.

if  to  the  Holder,  to  the  Holder  at  the  Holder’s  address,  facsimile  number  or  electronic  mail  address  as  shown  in  the
Company’s  records,  as  may  be  updated  in  accordance  with  the  provisions  hereof,  or  until  the  Holder  so  furnishes  an

Each such notice or other communication shall for all purposes of this Warrant be treated as effective or having been given

books and records will control absent fraud or error.

8

 
 
 
 
 
 
 
 
 
 
 
 
g. Severability.  If  any  provision  of  this  Warrant  becomes  or  is  declared  by  a  court  of  competent  jurisdiction  to  be  illegal,
unenforceable or void, portions of such provision, or such provision in its entirety, to the extent necessary, shall be severed from
this Warrant, and such illegal, unenforceable or void provision shall be replaced with a valid and enforceable provision that will
achieve, to the extent possible, the same economic, business and other purposes of the illegal, unenforceable or void provision.
The balance of this Warrant shall be enforceable in accordance with its terms.

Company and the Holder under this Warrant shall survive exercise of this Warrant.

INVESTMENT REPRESENTATION STATEMENT
AND
MARKET STAND-OFF AGREEMENT

INVESTOR:

___________________________________

COMPANY:

XENETIC BIOSCIENCES, INC.

SECURITIES:

THE WARRANT ISSUED ON DECEMBER 31, 2014 (THE  “WARRANT”) AND THE SECURITIES ISSUED OR
ISSUABLE  UPON  EXERCISE  THEREOF  (INCLUDING  UPON  SUBSEQUENT  CONVERSION  OF  THOSE
SECURITIES)

DATE:

___________________________________

In connection with the purchase or acquisition of the above-listed Securities, the undersigned Investor represents and warrants to,

and agrees with, the Company as follows:

1.

Investment Intent. The Investor understands that the Warrant and Warrant Shares (the “ Securities”)  are  “restricted  securities”  and
have not been and will not be registered under the Securities Act of 1933, as amended (the “Securities Act”) or any applicable state
securities law and is acquiring the Securities as principal for its own account and not with a view to, or for distributing or reselling
such Securities or any part thereof in violation of the Securities Act or any applicable state securities laws. The Investor is acquiring
the  Securities  hereunder  in  the  ordinary  course  of  its  business.  The  Investor  does  not  presently  have  any  agreement,  plan  or
understanding, directly or indirectly, with any person to distribute or effect any distribution of any of the Securities (or any securities
which are derivatives thereof) to or through any person or entity; the Investor is not a registered broker-dealer under Section 15 of
the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or an entity engaged in a business that would require it to be
so registered as a broker-dealer.

2.

Investor Status. At  the  time  the  Investor  was  offered  the  Securities,  it  was,  and  at  the  date  hereof  it  is,  either  (i)  an  “accredited
investor” as defined in Rule 501(a) under the Securities Act or (ii) not a “U.S. person” as defined in Rule 902 of Regulation S of the
Securities Act.

3. General  Solicitation.  The  Investor  is  not  acquiring  the  Securities  as  a  result  of  any  advertisement,  article,  notice  or  other
communication  regarding  the  Securities  published  in  any  newspaper,  magazine  or  similar  media  or  broadcast  over  television  or
radio or presented at any seminar or any other general advertisement.

4.

Investment  Experience.  The  Investor,  either  alone  or  together  with  its  representatives,  has  such  knowledge,  sophistication  and
experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in
the Securities, and has so evaluated the merits and risks of such investment. The Investor is able to bear the economic risk of an
investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

13

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
5. Access  to  Information.  The  Investor  acknowledges  that  it  has  been  afforded  (i)  the  opportunity  to  ask  such  questions  as  it  has
deemed  necessary  of,  and  to  receive  answers  from,  representatives  of  the  Company  concerning  the  terms  and  conditions  of  the
offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the Company and its
subsidiaries and their respective financial condition, results of operations, business, properties, management and prospects sufficient
to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or
can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the
investment.  The  Investor  has  sought  such  accounting,  legal  and  tax  advice  as  it  has  considered  necessary  to  make  an  informed
decision with respect to its acquisition of the Securities.

6. Brokers and Finders. No person will have, as a result of the transactions contemplated by the Warrant, any valid right, interest or
claim  against  or  upon  the  Company  or  the  Investor  for  any  commission,  fee  or  other  compensation  pursuant  to  any  agreement,
arrangement or understanding entered into by or on behalf of the Investor.

7.

Independent  Investment  Decision.  The  Investor  has  independently  evaluated  the  merits  of  its  decision  to  purchase  Securities
pursuant to the Warrant. The Investor understands that nothing in the Warrant or any other materials presented by or on behalf of the
Company  to  it  in  connection  with  the  purchase  of  the  Securities  constitutes  legal,  tax  or  investment  advice.  The  Investor  has
consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with
its purchase of the Securities.

8. Reliance on Exemptions. The Investor understands that the Securities being offered and sold to it in reliance on specific exemptions
from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the
truth  and  accuracy  of,  and  the  Investor’s  compliance  with,  the  representations,  warranties,  agreements,  acknowledgements  and
understandings of the Investor set forth herein in order to determine the availability of such exemptions and the eligibility of the
Investor to acquire the Securities.

9. No  Governmental  Review .  The  Investor  understands  that  no  United  States  federal  or  state  agency  or  any  other  government  or
governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of
the investment in the Securities nor have such authorities passed upon or endorsed the merits of the offering of the Securities.

10. Regulation M. The Investor is aware that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of

the Securities and other activities with respect to the Securities by the Investor.

11. Residency. The residency of the Investor (or, in the case of a partnership or corporation, such entity’s principal place of business) is

correctly set forth on the signature page hereto.

12. Market Stand-off. The Investor agrees that the Investor shall not sell or otherwise transfer, make any short sale of, grant any option
for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, of any shares of the
Company’s capital stock acquired through the exercise of the Warrant during the 180 day period following the commencement of
the  Company’s  public  offerings  (or  such  other  period  as  may  be  requested  by  the  Company  or  an  underwriter  to  accommodate
regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions).
The Investor further agrees that to the extent that the executive officers and directors of the Company are subject to a longer market
stand-off  period,  the  Investor  shall  be  subject  to  such  longer  market  stand-off  period  as  well.  The  Company  may  impose  stop
transfer instructions and may stamp each certificate with a legend with respect to the shares subject to the foregoing restriction until
the end of such 180 day (or other) period. The Investor agrees to execute a market stand-off agreement with the underwriters in the
offerings in customary form consistent with the provisions of this section.
