OVERVIEW

 PART I

We are a clinical-stage biopharmaceutical company focused on the development and commercialization of novel cancer immunotherapy products designed to utilize the power
of the patient’s own immune system to eliminate cancer cells. We aim to acquire rights to these technologies by licensing or otherwise acquiring an ownership interest in the
technologies, funding their research and development and eventually either out-licensing or bringing the technologies to market. We are currently developing our proprietary
Chimeric Antigen Receptor (CAR) engineered T cells (CAR-T) technology, which we licensed from Dr. Stephen Forman’s laboratory at the City of Hope National Medical
Center (COH). CAR-T uses the patient’s own T cells to engage and destroy specific tumors. The process involves selecting specific T cell subtypes, genetically engineering
them to express chimeric antigen T cell receptors and placing them back in the patient where they recognize and destroy cancer cells.

Several companies have promising CAR-T therapies that are in various phases of clinical and pre-clinical development and which target different cancer indications. Pursuant to
the  COH  license  agreement,  we  obtained  an  exclusive  license  to  intellectual  property  rights  pertaining  to  several  CAR-T  patents  developed  by  COH  for  the  treatment  and
diagnosis of all human diseases. Since the license is exclusive, worldwide and granted to us comprehensive rights as to use, manufacture and sale, thereby conveying practical
ownership of the intellectual property to us. We therefore view such intellectual property as proprietary.

Our exclusive license and sponsored research agreement with Dr. Stephen Forman’s laboratory at the COH encompasses specific chimeric T cell constructions and enabling
process technologies including linker technology improvements. This agreement covers the discovery, manufacturing and clinical development of novel CAR-T cells along with
specified rights to any and all inventions.

We are currently in Phase 1 trials treating glioblastoma patients. Dr. Forman’s laboratory has developed MB-101, a proprietary engineered CAR-T cells targeting Interleukin13
Receptor a2 or MB-101, which is overexpressed on the surface of glioblastoma cells. On December 29, 2016 an article in the New England Journal of Medicine reported that a
patient enrolled in the Phase 1 glioblastoma trial treated with MB-101 achieved a complete response.

We have started another Phase 1 study for the treatment of patients with acute myeloid leukemia (AML) with CD123 specific CAR-T we licensed from COH (MB-102). Dr.
Forman’s laboratory has developed a proprietary CAR-based targeting of CD123, which is overexpressed on the surface of AML cells.

Additionally,  under  our  sponsored  preclinical  research  agreement  with  COH,  the  COH  is  developing  additional  CAR-T  cell  constructions  targeting  a  number  of  tumor
associated antigens specific for the variety of solid and hematological malignancies. The effectiveness of certain of these additional CAR-T cell constructs already has been
demonstrated  in  preclinical  studies  with  mouse  xenograft  models  of  specific  human  tumors.  Under  the  sponsored  research  agreement,  we  have  the  right  to  license  newly
developed  CAR-T  constructs.  We  intend  to  further  pursue  preclinical  development  to  validate  and  seek  to  establish  the  proprietary  nature  of  the  most  promising  CAR-T
approaches coming out of the sponsored research program and, if successful, we would license and take forward into clinical studies.

To date, we have not received approval for the sale of our product candidates in any market and, therefore, have not generated any product sales from our product candidates.

We are a majority controlled subsidiary of Fortress Biotech, Inc. (“Fortress”).

IL13Ra2 CAR-T Cell or MB-101 Program for Glioblastoma

Glioblastoma  multiforme  (GBM)  is  the  most  common  brain  and  central  nervous  system  (CNS)  cancer,  accounting  for  15.1%  of  all  primary  brain  tumors,  and  55.1%  of  all
gliomas. There are an estimated 12,120 new glioblastoma cases predicted in 2016 in the U.S. Malignant brain tumors are the most common cause of cancer-related deaths in
adolescents  and  young  adults  aged  15-39  and  the  most  common  cancer  occurring  among  15-19  year  olds  in  the  U.S.  While  GBM  is  a  rare  disease  (2-3  cases  per  100,000
persons  per  year  in  the  U.S.  and  E.U.),  it  is  quite  lethal  with  5-year  survival  rates  historically  under  10%.  Standard  of  care  therapy  consists  of  maximal  surgical  resection,
radiation and chemotherapy with temozolomide, which, while rarely curative, are shown to extend median overall survival from 4.5 to 15 months. GBM remains difficult to
treat due to the inherent resistance of the tumor to conventional therapies.

Immunotherapy approaches targeting brain tumors offer promise over conventional treatments. IL13Ra2 is an attractive target for CAR-T therapy, as it has limited expression in
normal tissue but is over-expressed on the surface of greater than 50% of GBMs. CAR-T cells are designed to express membrane-tethered IL-13 receptor ligand (IL-13) mutated
at a single site (glutamic acid at position 13 to a tyrosine; E13Y) with high affinity for IL13Ra2 and reduced binding to IL13Ra1 in order to reduce healthy tissue targeting
(Kahlon, Cancer Research 2004).

We are developing an optimized CAR-T product incorporating enhancements in CAR-T design and T cell engineering to improve antitumor potency and T cell persistence. We
include a second generation hinge optimized CAR containing mutations in the IgG4 linker to reduce off target Fc interactions (Jonalaggada, Mol Therapy) as well as the 41BB
(CD137) co-stimulatory signaling domain for improved survival and maintenance of CAR-T cells as well as extracellular domain of CD19as a selection/ tracking marker. In
order to further improve persistence, central memory T-cells (TCM) are isolated and enriched. The manufacturing process limits ex vivo expansion, which is designed to reduce
T cell exhaustion and maintain a TCM phenotype. These CAR-T modified TCM cells are shown to be more potent and persistent than earlier generations of IL-13 based CAR-Ts
in mouse xenograft models of GBM.

We  currently  have  an  open  IND  to  assess  the  feasibility  and  safety  of  using  TCM  enriched  IL13Ra2-specific  CAR  engineered  T  cells  for  clinical  study  participants  with
recurrent/refractory malignant glioma. This IND was submitted on October 27, 2014, with COH as the sponsor. We have currently enrolled and treated the 17 patients as of
December 31, 2016. Our collaborators at the COH presented the preliminary data for this first cohort of patients. The investigators reported that the CAR-T cells were well
tolerated (meaning that no dose limiting toxicities were seen to date). The investigators also reported on a patient that they determined had a complete response to treatment
(based on the imaging and clinical features set forth by the Response Assessment in Neuro-Oncology Criteria (RANO)). This clinical response was sustained for 7.5 months
after the initiation of CAR T-cell therapy, unfortunately, this patient’s disease eventually recurred at four new locations that were distinct and non- adjacent to original tumors.
The next step is to continue to enroll patients in this Phase 1 study to determine the maximum tolerated dose, and a recommended Phase 2 dose. Additionally, in this Phase 1
study, we are exploring optimum modes of delivery for CAR-T cells for the treatment of GBM.

The clinical trial endpoints, which were first received on August 1, 2014 and are current as of July 7, 2016 are as follows:

Primary Objectives:

(1)  To  assess  the  feasibility  and  safety  of  intratumoral  (stratum  1)  or  intracavitary  (stratum  2)  or  intraventricular  (stratum  3)  or  dual  delivery  (stratum  4)  cellular
immunotherapy  utilizing  ex  vivo  expanded  autologous  central  memory  T  cells  (TCM)-enriched  T  cells  that  are  genetically  modified  using  a  self-inactivating  (SIN)
lentiviral vector to express a interleukin 13 receptor alpha 2 (IL13Rα2)-specific, hinge-optimized, 41BB-costimulatory chimeric antigen receptor (CAR), as well as a
truncated  human  cluster  of  differentiation  19  (CD19)  (IL13  [EQ]BBzeta/truncated  CD19[t]+  TCM)  (IL13Rα2-specific,  hinge-optimized,  41BB-costimulatory
CAR/truncated CD19-expressing T lymphocytes), for research participants with recurrent/refractory malignant glioma.

(2) To determine maximum tolerated dose schedule (MTD) and a recommended phase II dosing plan (RP2D) for each strata based on dose limiting toxicities (DLTs)
and the full toxicity profile.

Secondary Objectives:

(1) To assess the timing and extent of brain inflammation, as assessed by magnetic resonance imaging (MRI)/magnetic resonance spectroscopy (MRS), following T cell
administration.

(2) To describe cytokine levels (cyst fluid, peripheral blood) over the study period.

(3) In research participants who receive the full schedule of three T cell doses: estimate the six month progression free survival rate, disease response rates, and median
overall survival.

(4) In research participants who receive intraventricular infusions after progressing following intracranial infusions (stratum 1 or 2): estimate disease response rate and
overall survival if the sample size is large enough.

5

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
(5)  In  research  participants  who  receive  at  least  one  dose  of  T  cells  estimate  the  mean  change  from  baseline  in  quality  of  life  using  the  European  Organization  for
Research and Treatment of Cancer (EORTC) quality of life questionnaire (QLQ)-C30 and EORTC QLQ brain neoplasm (BN)-20 survey scale, domain and item scores
during and post treatment.

(6) For study participants who undergo a second resection or autopsy: To evaluate T cell persistence in the tumor micro-environment and the location of the T cells with
respect to the injection site, and to evaluate IL13Ra2 antigen expression levels pre and post T cell therapy.

CD 123 CAR T cell Program for AML

Overview

CD123  is  a  subunit  of  the  heterodimeric  interleukin-3-receptor  (IL-3R)  which  is  widely  expressed  on  human  hematologic  malignancies  including  acute  myeloid  leukemia
(AML). In addition, CD123 can be found on the surface of B cell acute lymphoblastic leukemia (B-ALL), hairy cell leukemia, blastic plasmacytoid dendritic cell neoplasm
(BPDCN), chronic myeloid leukemia (CML) and Hodgkin’s lymphoma.

Of these malignancies, we are currently investigating CD123 as a target for adoptive cellular immunotherapy in AML since high CD123 expression is associated with enhanced
AML blast proliferation, increased resistance of blasts to apoptosis, and poor clinical prognosis.

Acute Myeloid Leukemia is a cancer of the myeloid line of blood cells characterized by rapid growth of abnormal white blood cells that accumulate in the bone marrow. AML
is the most common form of acute leukemia. Although AML is a relatively rare disease there are approximately 20,000 new cases per year in the US and 10,000 deaths per
year, accounting for approximately 1.8% of cancer deaths in the US (The Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute). AML
standard of care involves chemotherapy to induce remission followed by additional chemotherapy or hematopoietic stem cell transplant. Allogeneic stem cell transplantation is
the preferred treatment route for AML following a second remission. It can lead to a 5-year disease free survival in 26% of patients. Unfortunately, however, currently, only
about half of relapsed patients are able to achieve a second remission with traditional chemotherapy agents. Patients who do not achieve a second remission are much less likely
to benefit from transplantation and face a dismal outcome.

The use of CAR-T immunotherapy in relapsed AML patients may offer the potential to achieve a complete or longer lasting remission. We have developed CD123 targeted
CAR-T cells designed both to be activated to proliferate and to kill CD123 expressing tumor cells (Mardiros A, Santos C Dos. T cells expressing CD123-specific chimeric
antigen receptors exhibit specific cytolytic effector functions and antitumor effects against human acute myeloid leukemia. Blood. 2013;122(18):3138-3148). The therapy is
designed  to  recognize  and  eliminate  leukemic  cells,  leading  to  remission  in  patients  with  relapsed  or  refractory AML,  and  could  serve  as  a  bridge  to  potentially  curative
allogenic stem cell transplant. The manufacturing process genetically modifies T cells isolated from peripheral blood mononuclear cells in order to express a CD123-specific,
hinge–optimized, CD28 co-stimulatory domain expressing CAR as well as a truncated EGFR (EGFRt) selection/tracking marker (Wang Blood). EGFRt also has the potential to
act as a safety switch to allow depletion of CAR-T cells in the patients if needed.

We have an open IND for a Phase 1 clinical study to assess the anti-tumor activity and safety of administering CAR T cells and we have treated three patients as of December
31, 2016. This IND was submitted on April 20, 2015, with COH as the sponsor. We will assess the T cell persistence and determine the potential immunogenicity of the cells to
determine a recommended Phase 2 dose.

The clinical trial endpoints, which were first received on June 6, 2014 and are current as of July 7, 2016 are as follows:

Primary Objectives:

(1) To assess the anti-tumor activity and safety of cellular immunotherapy utilizing ex vivo expanded T cells that are genetically modified using a self-inactivating (SIN)
lentiviral vector to express a co-stimulatory cluster of differentiation (CD)123-specific chimeric antigen receptor (CAR) as well as a truncated human epidermal growth
factor  receptor  (EGFR)  (CD123R[EQ]28zeta[Z]/truncated  human  EGFR  [EGFRt]+  T  cells)  (anti  CD123-CAR/CD28-costimulatory,  lentiviral  vector-transduced
autologous T lymphocytes) following lymphodepletion for patients with relapsed or refractory AML.

(2) To determine the recommended Phase II dose (RP2D).

Secondary Objectives:

(1) To assess activity in the form of T cell persistence and immunogenicity of CD123R(EQ)28Z/EGFRt+ T cells up to 28 days post T cell infusion.

6

 
 
 
 
 
 
   
 
  
 
 
 
 
 
 
 
 
 
 
Tertiary Objectives:

(1) To assess impact on hematopoiesis, change from baseline in numbers of CD123+ blood cells, CD123 expression on leukemia cells and hematopoietic cells, and the
clinical efficacy of EGFRt mediated CAR T cell ablation.

COSTS AND TIME TO COMPLETE PRODUCT DEVELOPMENT

The information below provides estimates regarding the costs associated with the completion of the current development phase and our current estimated range of the time that
will be necessary to complete that development phase for our product candidates. For a description of the risk factors that could significantly affect our ability to meet these cost
and time estimates, see Item 1A of this Form 10-K.

Completion dates and costs in the above table are estimates due to the uncertainties associated with preclinical research activities, clinical trials and the related requirements of
development. In the cases where the requirements for preclinical development, clinical trials and development programs have not been fully defined, or are dependent on the
success of other research findings or trials, we cannot estimate trial completion or cost with any certainty. The actual spending on each trial or the decision to advance programs
to the next stage during the year is also dependent on funding.

INTELLECTUAL PROPERTY AND PATENTS

General

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

We also depend upon the skills, knowledge and experience of our scientific and technical personnel, as well as that of our advisors, consultants and other contractors (“know-
how”). To help protect our proprietary know-how which is not patentable, and for inventions for which patents may be difficult to enforce, we rely on trade secret protection and
confidentiality agreements to protect our interests.  To this end, we require all employees, consultants, advisors and other contractors to enter into confidentiality agreements
which prohibit the disclosure of confidential information and, where applicable, require disclosure and assignment to us of the ideas, developments, discoveries and inventions
important to our business.

Patents  and  other  proprietary  rights  are  crucial  to  the  development  of  our  business.  We  will  be  able  to  protect  our  proprietary  technologies  from  unauthorized  use  by  third
parties only to the extent that our proprietary rights are covered by valid and enforceable patents, supported by regulatory exclusivity or are effectively maintained as trade
secrets. We have a few patents and patent applications related to our compounds and other technology, but we cannot guarantee the scope of protection of the issued patents, or
that such patents will survive a validity or enforceability challenge, or that any of the pending patent applications will issue as patents.

Generally, patent applications in the US are maintained in secrecy for a period of 18 months or more. The patent positions of biotechnology and pharmaceutical companies are
highly uncertain and involve complex legal and factual questions. Therefore, we cannot predict the breadth of claims allowed in biotechnology and pharmaceutical patents, or
their enforceability. To date, there has been no consistent policy regarding the breadth of claims allowed in biotechnology patents. Third parties or competitors may challenge or
circumvent our patents or patent applications, if issued. If our competitors prepare and file patent applications in the US that claim technology also claimed by us, we may have
to participate in interference proceedings declared by the US Patent and Trademark Office (PTO) to determine priority of invention, which could result in substantial cost, even
if the eventual outcome is favorable to us. Because of the extensive time required for development, testing and regulatory review of a potential product, it is possible that before
we commercialize any of our products, any related patent may expire or remain in existence for only a short period following commercialization, thus reducing any advantage
of  the  patent.  However,  the  life  of  a  patent  covering  a  product  that  has  been  subject  to  regulatory  approval  may  have  the  ability  be  extended  through  the  patent  restoration
program, although any such extension could still be minimal.

If a patent is issued to a third party containing one or more preclusive or conflicting claims, and those claims are ultimately determined to be valid and enforceable, we may be
required to obtain a license under such patent or to develop or obtain alternative technology. In the event of litigation involving a third party claim, an adverse outcome in the
litigation could subject us to significant liabilities to such third party, require us to seek a license for the disputed rights from such third party, and/or require us to cease use of
the technology. Further, our breach of an existing license or failure to obtain a license to technology required to commercialize our products may seriously harm our business.
We also may need to commence litigation to enforce any patents issued to us or to determine the scope and validity of third-party proprietary rights. Litigation would involve
substantial costs.

In  March  2015  we  licensed  intellectual  property  related  to  CAR-T  technology  from  City  of  Hope.  The  intellectual  property  includes  patent  applications  in  a  number  of
countries, including the US and the EU, as well as pending patent applications in Japan and the developing world. These pending patent applications include compositions and
methods of creating CAR-T cells targeting IL13Ra and CD123. The applications include various claims regarding additional specific features to optimize targeting, binding
specificity, cell stimulation and persistence. Additional patents and pending claims we have rights to include the use of optimized hinge region for many targeted constructions
such  as  CD19  along  with  compositions  and  methods  to  isolate  and  transfect  T  memory  cells  to  improve  cellular  persistence.  Any  patents  maturing  from  these  pending
applications will expire no sooner than October 2033.

In  total,  we  have  in-licensed  four  patents  in  the  US  and  four  patents  outside  the  US.  We  are  currently  evaluating  the  terms  of  license  agreements  that  would  grant  us  12
additional US patents and 36 patents outside the US.

Our sponsored research agreement gives us the right to first negotiation under specified maximum terms regarding any future inventions arising from Dr. Forman’s laboratory.

Other Intellectual Property Rights

We depend upon trademarks, trade secrets, knowhow and continuing technological advances to develop and maintain our competitive position. To maintain the confidentiality
of  trade  secrets  and  proprietary  information,  we  require  our  employees,  scientific  advisors,  consultants  and  collaborators,  upon  commencement  of  a  relationship  with  us,  to
execute confidentiality agreements and, in the case of parties other than our research and development collaborators, to agree to assign their inventions to us. These agreements
are designed to protect our proprietary information and to grant us ownership of technologies that are developed in connection with their relationship with us. These agreements
may not, however, provide protection for our trade secrets in the event of unauthorized disclosure of such information.

In addition to patent protection, we may utilize orphan drug regulations or other provisions of the Food, Drug and Cosmetic Act of 1938, as amended, or FDCA, to provide
market  exclusivity  for  certain  of  our  product  candidates.  Orphan  drug  regulations  provide  incentives  to  pharmaceutical  and  biotechnology  companies  to  develop  and
manufacture  drugs  for  the  treatment  of  rare  diseases,  currently  defined  as  diseases  that  exist  in  fewer  than  200,000  individuals  in  the  US,  or  diseases  that  affect  more  than
200,000 individuals in the US but for which the sponsor does not realistically anticipate will generate a net profit. Under these provisions, a manufacturer of a designated orphan
drug can seek tax benefits, and the holder of the first approval of a designated orphan product from the Food and Drug Administration (FDA), will be granted a seven year
period of marketing exclusivity for such FDA approved orphan product.

LICENSING AGREEMENTS AND COLLABORATIONS

City of Hope Agreements

In March 2015, we entered into an Exclusive License Agreement with COH (the “Original Agreement”) to acquire intellectual property rights pertaining to CAR-T technology.
In April  2015,  pursuant  to  the  agreement,  we  paid  COH  an  upfront  fee  of  $2.0  million  and  granted  COH  1,000,000  shares  of  Class A  Common  Stock,  representing  10%
ownership  of  Mustang,  as  of  such  date.  In  March  2017,  COH  was  granted  293,588  additional  shares  of  the  Company’s  Common  Stock,  valued  at  $5.73  per  share  or
approximately $1.7 million as of October 2016, the effective date of the grant. The additional grant was made pursuant to the terms of the agreement, which maintained COH
ownership at 10% until the Company raised net proceeds of $10.0 million from third party investors. The agreement was amended in February 2017, to allow for the grant of
stock to be made in the Company’s common shares rather than Class A common shares as originally prescribed.

In addition, we entered into a sponsored research agreement with COH in which we will fund continued research in the amount of $2.0 million per year, payable in four equal
installments, over the next five years.

On February 17, 2017, we and COH amended and restated the Original Agreement in connection with the covered patents by entering into three separate amended and restated
exclusive license agreements, one relating to CD123, one relating to IL-13 and one relating to the spacer technology, that amended the Original Agreement in certain other
respects, and collectively replace the Original Agreement in its entirety. The total potential consideration payable to COH by us, in equity or cash, did not, in the aggregate,
change materially from the Original Agreement.

A&R CD123 License

On February 17, 2017, we entered into an Amended and Restated Exclusive License Agreement with COH to acquire intellectual property rights pertaining to CD123 patent
rights (the “A&R CD123 License”). Pursuant to the A&R CD123 License, we and COH acknowledge that an upfront fee has already been paid under the Original Agreement.
In  addition,  an  annual  maintenance  fee  will  continue  to  apply.  COH  is  eligible  to  receive  milestone  payments  totaling  approximately  $14.5  million  upon  and  subject  to  the
achievement of certain milestones. Royalty payments in the mid-single digits are due on net sales of licensed products. We are obligated to pay COH a percentage of certain
revenues received in connection with a sublicense in the mid-teens to mid-thirties, depending on the timing of the sublicense in the development of any product. In addition,
equity grants made under the Original Agreement were acknowledged, and the anti-dilution provisions of the Original Agreement were carried forward.

A&R IL-13 License

On February 17, 2017, we entered into an Amended and Restated Exclusive License Agreement with COH to acquire intellectual property rights pertaining to IL-13 patent
rights (the “A&R IL-13 License”). Pursuant to the A&R IL-13 License, we and COH acknowledge that an upfront fee has already been paid under the Original Agreement. In
addition,  an  annual  maintenance  fee  will  continue  to  apply.  COH  is  eligible  to  receive  milestone  payments  totaling  approximately  $14.5  million  upon  and  subject  to  the
achievement of certain milestones. Royalty payments in the mid-single digits are due on net sales of licensed products. We are obligated to pay COH a percentage of certain
revenues received in connection with a sublicense in the mid-teens to mid-thirties, depending on the timing of the sublicense in the development of any product. In addition,
equity grants made under the Original Agreement were acknowledged, and the anti-dilution provisions of the Original Agreement were carried forward.

A&R Spacer License

On February 17, 2017, we entered into an Amended and Restated Exclusive License Agreement with COH to acquire intellectual property rights pertaining to Spacer patent
rights (the “A&R Spacer License”). Pursuant to the A&R Spacer License, we and COH acknowledged that an upfront fee has already been paid under the Original Agreement.
In addition, an annual maintenance fee will continue to apply. No royalties are due if the Spacer technology is used in conjunction with a CD123 CAR or an IL-13 CAR, and
royalty  payments  in  the  low  single  digits  are  due  on  net  sales  of  licensed  products  if  the  Spacer  technology  is  used  in  conjunction  with  other  intellectual  property.  We  are
obligated  to  pay  COH  a  percentage  of  certain  revenues  received  in  connection  with  a  sublicense  in  the  mid-thirties.  In  addition,  equity  grants  made  under  the  Original
Agreement were acknowledged, and the anti-dilution provisions of the Original Agreement were carried forward. 

IV/ICV Agreement

On February 17, 2017, we entered into an exclusive license agreement (the “IV/ICV Agreement”) with COH to acquire intellectual property rights in patent applications related
to the intraventricular and intracerebroventricular methods of delivering T cells that express CARs. Pursuant to the IV/ICV Agreement, we will pay COH an upfront fee of
$125,000 within 30 days of the Effective Date, in addition to an annual maintenance fee. COH is eligible to receive milestone payments totaling approximately $125,000, upon
and subject to the achievement of certain milestones. Royalty payments in the low single digits are due on net sales of licensed products and revenue from sublicenses.

UCLA Agreement

On March 17, 2017, we entered into an exclusive license agreement (the “UCLA Agreement”) with the Regents of the University of California (“UCLA”) to acquire intellectual
property rights in patent applications related to the engineered anti-prostate stem cell antigen antibodies for cancer targeting and detection. Pursuant to the Agreement, we will
pay UCLA an upfront fee of $200,000 within 30 days of the March 17, 2017, in addition to an annual maintenance fee. UCLA is eligible to receive milestone payments totaling
approximately $14.3 million, upon and subject to the achievement of certain milestones.  Royalty payments in the mid-single digits are due on net sales of licensed products,
and we are obligated to pay UCLA a percentage of certain revenues received in connection with a sublicense in the mid-single digits to mid-twenties, depending on the timing of
the sublicense in the development of such product.

The term of the Agreement expires after the expiration of the last to expire of any of the patent rights under the Agreement. Either we or UCLA may terminate the Agreement
upon notice to the other upon breach without remedy or upon insolvency. In addition, we may terminate the Agreement at will without cause after adequate notice.

COMPETITION

Competition  in  the  pharmaceutical  and  biotechnology  industries  is  intense.  Our  competitors  include  pharmaceutical  companies  and  biotechnology  companies,  as  well  as
universities and public and private research institutions. In addition, companies that are active in different but related fields represent substantial competition for us. Many of
our  competitors  have  significantly  greater  capital  resources,  larger  research  and  development  staffs  and  facilities  and  greater  experience  in  drug  development,  regulation,
manufacturing and marketing than we do. These organizations also compete with us to recruit qualified personnel, attract partners for joint ventures or other collaborations, and
license  technologies  that  are  competitive  with  ours.  To  compete  successfully  in  this  industry  we  must  identify  novel  and  unique  drugs  or  methods  of  treatment  and  then
complete the development of those drugs as treatments in advance of our competitors.

The  drugs  that  we  are  attempting  to  develop  will  have  to  compete  with  existing  therapies.  In  addition,  a  large  number  of  companies  are  pursuing  the  development  of
pharmaceuticals  that  target  the  same  conditions  that  we  are  targeting.  Other  companies  have  products  or  product  candidates  in  various  stages  of  pre-clinical  or  clinical
development, or with marketing approvals, to treat conditions for which we are also seeking to discover and develop product candidates. Some of these potential competing
drugs are further advanced in development than our product candidates and may be commercialized earlier.

The field of CAR-T therapy is extremely active. Companies and partnerships currently engaged in clinical trials with CAR-T modalities include Juno, Novartis/University of
Pennsylvania, Bluebird Bio, Celgene/Baylor College of Medicine, Pfizer/Cellectis, Amgen/Kite Pharma, Bellicum, MD Anderson/Ziopharm and Intrexon.

EMPLOYEES

As December 31, 2016, we have no fulltime employees and three part-time employees. We anticipate that each part-time employee will devote between 5 to 15 hours per week
to Mustang. Employees of Fortress also make valuable financial, legal, scientific and other strategic contributions to Mustang on a regular basis.

SUPPLY AND MANUFACTURING

As an early stage development company, we rely on COH to manufacture all materials currently used in the clinical development programs we are sponsoring at COH. Pursuant
to the March 2015 Licensing Agreement with COH, we have the right to make and have made the products, and we are currently negotiating Investigator-Initiated Clinical
Research  Support Agreements  with  COH  which  specify  the  manufacturing  costs  and  numbers  of  patients  which  will  be  supplied  under  filed  protocols.  COH  has  extensive
experience manufacturing clinical materials for development studies, but we are currently dependent on both their capacity limitations and continued operating success.

We have limited experience in manufacturing products for clinical or commercial purposes. We currently do not have any manufacturing capabilities. We have established, or
intend to establish, contract manufacturing relationships for the preliminary supplies of our product candidates, in each case with a single manufacturer. As with any supply
program, obtaining raw materials of the correct quality cannot be guaranteed, and we cannot ensure that we will be successful in this endeavor.

At the time of commercial sale, to the extent possible and commercially practicable, we would seek to engage a back-up supplier for each of our product candidates. Until such
time, we expect that we will rely on a single contract manufacturer to produce each of our product candidates under current Good Manufacturing Practice (“cGMP”) regulations.
Our  third-party  manufacturers  have  a  limited  number  of  facilities  in  which  our  product  candidates  can  be  produced  and  will  have  limited  experience  in  manufacturing  our
product  candidates  in  quantities  sufficient  for  commercialization.  Our  third-party  manufacturers  will  have  other  clients  and  may  have  other  priorities  that  could  affect  their
ability to perform the work satisfactorily and/or on a timely basis. Both of these occurrences would be beyond our control. 

We expect to similarly rely on contract manufacturing relationships for any products that we may in-license or acquire in the future. However, there can be no assurance that we
will be able to successfully contract with such manufacturers on terms acceptable to us, or at all.

Contract manufacturers are subject to ongoing periodic and unannounced inspections by the FDA, the US Drug Enforcement Administration (DEA) and corresponding state
agencies to ensure strict compliance with cGMP and other state and federal regulations. Our contractors, if any, in Europe face similar challenges from the numerous EU and
member state regulatory agencies and authorized bodies. We do not have control over third-party manufacturers’ compliance with these regulations and standards, other than
through contractual obligations. If they are deemed out of compliance with cGMPs, product recalls could result, inventory could be destroyed, production could be stopped and
supplies could be delayed or otherwise disrupted.

If we need to change manufacturers after commercialization, the FDA and corresponding foreign regulatory agencies must approve these new manufacturers in advance, which
will  involve  testing  and  additional  inspections  to  ensure  compliance  with  FDA  regulations  and  standards  and  may  require  significant  lead  times  and  delay.  Furthermore,
switching manufacturers may be difficult because the number of potential manufacturers is limited. It may be difficult or impossible for us to find a replacement manufacturer
quickly or on terms acceptable to us, or at all.

GOVERNMENT AND INDUSTRY REGULATIONS

Numerous  governmental  authorities,  principally  the  FDA  and  corresponding  state  and  foreign  regulatory  agencies,  impose  substantial  regulations  upon  the  clinical
development,  manufacture  and  marketing  of  our  product  candidates,  as  well  as  our  ongoing  research  and  development  activities.  None  of  our  product  candidates  has  been
approved for sale in any market in which we have marketing rights. Before marketing in the US, any drug that we develop must undergo rigorous pre-clinical testing and clinical
trials and an extensive regulatory approval process implemented by the FDA under the FDCA. The FDA regulates, among other things, the pre-clinical and clinical testing,
safety,  efficacy,  approval,  manufacturing,  record  keeping,  adverse  event  reporting,  packaging,  labeling,  storage,  advertising,  promotion,  export,  sale  and  distribution  of
biopharmaceutical products.

10

 
 
 
 
 
 
 
 
 
 
 
   
 
 
 
 
The regulatory review and approval process is lengthy, expensive and uncertain. We are required to submit extensive pre-clinical and clinical data and supporting information to
the FDA for each indication or use to establish a product candidate’s safety and efficacy before we can secure FDA approval to market or sell a product in the US. The approval
process  takes  many  years,  requires  the  expenditure  of  substantial  resources  and  may  involve  ongoing  requirements  for  post-marketing  studies  or  surveillance.  Before
commencing clinical trials in humans, we must submit an IND to the FDA containing, among other things, pre-clinical data, chemistry, manufacturing and control information,
and an investigative plan. Our submission of an IND may not result in FDA authorization to commence a clinical trial.

The FDA may permit expedited development, evaluation, and marketing of new therapies intended to treat persons with serious or life-threatening conditions for which there is
an unmet medical need under its fast track drug development programs. A sponsor can apply for fast track designation at the time of submission of an IND, or at any time prior
to receiving marketing approval of the new drug application (NDA). To receive fast track designation, an applicant must demonstrate:

·

·

·

that the drug is intended to treat a serious or life-threatening condition;

that the drug is intended to treat a serious aspect of the condition; and

that the drug has the potential to address unmet medical needs, and this potential is being evaluated in the planned drug development program.

The FDA must respond to a request for fast track designation within 60 calendar days of receipt of the request. Over the course of drug development, a product in a fast track
development program must continue to meet the criteria for fast track designation. Sponsors of products in fast track drug development programs must be in regular contact with
the reviewing division of the FDA to ensure that the evidence necessary to support marketing approval will be developed and presented in a format conducive to an efficient
review. Sponsors of products in fast track drug development programs ordinarily are eligible for priority review of a completed application in six months or less and also may be
permitted to submit portions of an NDA to the FDA for review before the complete application is submitted.

Sponsors  of  drugs  designated  as  fast  track  also  may  seek  approval  under  the  FDA’s  accelerated  approval  regulations.  Under  this  authority,  the  FDA  may  grant  marketing
approval  for  a  new  drug  product  on  the  basis  of  adequate  and  well-controlled  clinical  trials  establishing  that  the  drug  product  has  an  effect  on  a  surrogate  endpoint  that  is
reasonably likely, based on epidemiologic, therapeutic, pathophysiologic, or other evidence, to predict clinical benefit or on the basis of an effect on a clinical endpoint other
than survival or irreversible morbidity.   Approval will be subject to the requirement that the applicant study the drug further to verify and describe its clinical benefit where
there is uncertainty as to the relation of the surrogate endpoint to clinical benefit or uncertainty as to the relation of the observed clinical benefit to ultimate outcome.  Post-
marketing studies are usually underway at the time an applicant files the NDA.  When required to be conducted, such post-marketing studies must also be adequate and well-
controlled.    The  applicant  must  carry  out  any  such  post-marketing  studies  with  due  diligence.  Many  companies  who  have  been  granted  the  right  to  utilize  an  accelerated
approval approach have failed to obtain approval. Moreover, negative or inconclusive results from the clinical trials we hope to conduct or adverse medical events could cause
us to have to repeat or terminate the clinical trials. Accordingly, we may not be able to complete the clinical trials within an acceptable time frame, if at all, and, therefore, could
not submit the NDA to the FDA or foreign regulatory authorities for marketing approval.

Clinical  testing  must  meet  requirements  for  institutional  review  board  oversight,  informed  consent  and  good  clinical  practices,  and  must  be  conducted  pursuant  to  an  IND,
unless exempted.

For purposes of NDA approval, clinical trials are typically conducted in the following sequential phases:

·

·

·

·

Phase  1:  The  drug  is  administered  to  a  small  group  of  humans,  either  healthy  volunteers  or  patients,  to  test  for  safety,  dosage  tolerance,  absorption,  metabolism,
excretion and clinical pharmacology.

Phase 2: Studies are conducted on a larger number of patients to assess the efficacy of the product, to ascertain dose tolerance and the optimal dose range, and to gather
additional data relating to safety and potential adverse events.

Phase 3: Studies establish safety and efficacy in an expanded patient population.

Phase 4: The FDA may require Phase 4 post-marketing studies to find out more about the drug’s long-term risks, benefits, and optimal use, or to test the drug in different
populations.

The length of time necessary to complete clinical trials varies significantly and may be difficult to predict. Clinical results are frequently susceptible to varying interpretations
that may delay, limit or prevent regulatory approvals. Additional factors that can cause delay or termination of our clinical trials, or that may increase the costs of these trials,
include:

·

·

slow patient enrollment due to the nature of the clinical trial plan, the proximity of patients to clinical sites, the eligibility criteria for participation in the study or other
factors;

inadequately trained or insufficient personnel at the study site to assist in overseeing and monitoring clinical trials or delays in approvals from a study site’s review board;

11

 
 
 
 
 
 
 
 
   
 
 
 
 
 
 
 
 
 
 
 
·

·

·

·

longer treatment time required to demonstrate efficacy or determine the appropriate product dose;

insufficient supply of the product candidates;

adverse medical events or side effects in treated patients; and

ineffectiveness of the product candidates.

In addition, the FDA, equivalent foreign regulatory authority, or a data safety monitoring committee for a trial may place a clinical trial on hold or terminate it if it concludes that
subjects are being exposed to an unacceptable health risk, or for futility. Any drug is likely to produce some toxicity or undesirable side effects in animals and in humans when
administered at sufficiently high doses and/or for a sufficiently long period of time. Unacceptable toxicity or side effects may occur at any dose level at any time in the course of
studies in animals designed to identify unacceptable effects of a product candidate, known as toxicological studies, or clinical trials of product candidates. The appearance of
any unacceptable toxicity or side effect could cause us or regulatory authorities to interrupt, limit, delay or abort the development of any of our product candidates and could
ultimately prevent approval by the FDA or foreign regulatory authorities for any or all targeted indications.

Sponsors of drugs may apply for a special protocol assessment (SPA) from the FDA. The SPA process is a procedure by which the FDA provides official evaluation and written
guidance on the design and size of proposed protocols that are intended to form the basis for a NDA. However, final marketing approval depends on the results of efficacy, the
adverse event profile and an evaluation of the benefit/risk of treatment demonstrated in the Phase 3 trial. The SPA may only be changed through a written agreement between
the sponsor and the FDA, or if the FDA becomes aware of a substantial scientific issue essential to product safety or efficacy. 

Before receiving FDA approval to market a product, we must demonstrate that the product is safe and effective for its intended use by submitting to the FDA a NDA containing
the pre-clinical and clinical data that have been accumulated, together with chemistry and manufacturing and controls specifications and information, and proposed labeling,
among  other  things.  The  FDA  may  refuse  to  accept  a  NDA  for  filing  if  certain  content  criteria  are  not  met  and,  even  after  accepting  an  NDA,  the  FDA  may  often  require
additional information, including clinical data, before approval of marketing a product.

It  is  also  becoming  more  common  for  the  FDA  to  request  a  Risk  Evaluation  and  Mitigation  Strategy,  or  REMS,  as  part  of  a  NDA.  The  REMS  plan  contains  post-market
obligations of the sponsor to train prescribing physicians, monitor off-label drug use, and conduct sufficient Phase 4 follow-up studies and registries to ensure the continued safe
use of the drug.

As part of the approval process, the FDA must inspect and approve each manufacturing facility. Among the conditions of approval is the requirement that a manufacturer’s
quality control and manufacturing procedures conform to cGMP. Manufacturers must expend significant time, money and effort to ensure continued compliance, and the FDA
conducts periodic inspections to certify compliance. It may be difficult for our manufacturers or us to comply with the applicable cGMP, as interpreted by the FDA, and other
FDA regulatory requirements. If we, or our contract manufacturers, fail to comply, then the FDA may not allow us to market products that have been affected by the failure.

If the FDA grants approval, the approval will be limited to those conditions and patient populations for which the product is safe and effective, as demonstrated through clinical
studies. Further, a product may be marketed only in those dosage forms and for those indications approved in the NDA. Certain changes to an approved NDA, including, with
certain  exceptions,  any  significant  changes  to  labeling,  require  approval  of  a  supplemental  application  before  the  drug  may  be  marketed  as  changed. Any  products  that  we
manufacture or distribute pursuant to FDA approvals are subject to continuing monitoring and regulation by the FDA, including compliance with cGMP and the reporting of
adverse experiences with the drugs. The nature of marketing claims that the FDA will permit us to make in the labeling and advertising of our products will generally be limited
to those specified in FDA approved labeling, and the advertising of our products will be subject to comprehensive monitoring and regulation by the FDA. Drugs whose review
was  accelerated  may  carry  additional  restrictions  on  marketing  activities,  including  the  requirement  that  all  promotional  materials  are  pre-submitted  to  the  FDA.  Claims
exceeding those contained in approved labeling will constitute a violation of the FDCA. Violations of the FDCA or regulatory requirements at any time during the product
development process, approval process, or marketing and sale following approval may result in agency enforcement actions, including withdrawal of approval, recall, seizure of
products, warning letters, injunctions, fines and/or civil or criminal penalties. Any agency enforcement action could have a material adverse effect on our business.

Failure to comply with applicable federal, state and foreign laws and regulations would likely have a material adverse effect on our business. In addition, federal, state and
foreign laws and regulations regarding the manufacture and sale of new drugs are subject to future changes.

Other Healthcare Laws and Compliance Requirements

In  the  US,  our  activities  are  potentially  subject  to  regulation  by  various  federal,  state  and  local  authorities  in  addition  to  the  FDA,  including  the  Centers  for  Medicare  and
Medicaid Services (formerly the Health Care Financing Administration), other divisions of the United States Department of Health and Human Services (e.g., the Office of
Inspector General), the United States Department of Justice and individual United States Attorney offices within the Department of Justice, and state and local governments.

Pharmaceutical Coverage, Pricing and Reimbursement

In  the  US  and  markets  in  other  countries,  sales  of  any  products  for  which  we  receive  regulatory  approval  for  commercial  sale  will  depend  in  part  on  the  availability  of
reimbursement from third-party payors, including government health administrative authorities, managed care providers, private health insurers and other organizations. Third-
party payors are increasingly examining the medical necessity and cost-effectiveness of medical products and services, in addition to their safety and efficacy, and, accordingly,
significant  uncertainty  exists  as  to  the  reimbursement  status  of  newly  approved  therapeutics. Adequate  third  party  reimbursement  may  not  be  available  for  our  products  to
enable  us  realize  an  appropriate  return  on  our  investment  in  research  and  product  development.  We  are  unable  to  predict  the  future  course  of  federal  or  state  health  care
legislation and regulations, including regulations that will be issued to implement provisions of the health care reform legislation enacted in 2010, known as the Affordable Care
Act. The Affordable Care Act and further changes in the law or regulatory framework could have a material adverse effect on our business.

International Regulation

In addition to regulations in the US, there are a variety of foreign regulations governing clinical trials and commercial sales and distribution of any product candidates. The
approval process varies from country to country, and the time may be longer or shorter than that required for FDA approval.  

 Item 1A.

Risk Factors

The following information sets forth risk factors that could cause our actual results to differ materially from those contained in forward-looking statements we have made in this
Form 10-K and those we may make from time to time. You should carefully consider the risks described below, in addition to the other information contained in this Form 10-
K, before making an investment decision. Our business, financial condition or results of operations could be harmed by any of these risks. The risks and uncertainties described
below are not the only ones we face. Additional risks not presently known to us or other factors not perceived by us to present significant risks to our business at this time also
may impair our business operations.

Risks Related to Our Business and Industry

We  currently  have  no  drug  products  for  sale.  We  are  heavily  dependent  on  the  success  of  our  product  candidates,  and  we  cannot  give  any  assurances  that  any  of  our
product candidates will receive regulatory approval or be successfully commercialized.

To date, we have invested a significant portion of our efforts and financial resources in the acquisition and development of our product candidates. We have not demonstrated
our ability to perform the functions necessary for the successful acquisition, development or commercialization of the technologies we are seeking to develop. As an early stage
company,  we  have  limited  experience  and  have  not  yet  demonstrated  an  ability  to  successfully  overcome  many  of  the  risks  and  uncertainties  frequently  encountered  by
companies in new and rapidly evolving fields, particularly in the biopharmaceutical area. Our future success is substantially dependent on our ability to successfully develop,
obtain  regulatory  approval  for,  and  then  successfully  commercialize  such  product  candidates.  Our  product  candidates  are  currently  in  preclinical  development  or  in  clinical
trials.  Our  business  depends  entirely  on  the  successful  development  and  commercialization  of  our  product  candidates,  which  may  never  occur.  We  currently  generate  no
revenues from sales of any drugs, and we may never be able to develop or commercialize a marketable drug.

The  successful  development,  and  any  commercialization,  of  our  technologies  and  any  product  candidates  would  require  us  to  successfully  perform  a  variety  of  functions,
including:

·

·

·

·

·

·

·

developing our technology platform;

identifying, developing, manufacturing and commercializing product candidates;

entering into successful licensing and other arrangements with product development partners;

participating in regulatory approval processes;

formulating and manufacturing products;

obtaining sufficient quantities of our product candidates from our third-party manufacturers as required to meet clinical trial needs and commercial demand at launch
and thereafter;

establishing and maintaining agreements with wholesalers, distributors and group purchasing organizations on commercially reasonable terms;

13

 
 
 
 
 
 
 
   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
·

conducting sales and marketing activities including hiring, training, deploying and supporting our sales force and creating market demand for our product candidates
through our own marketing and sales activities, and any other arrangements to promote our product candidates that we may later establish; and

· maintaining patent protection and regulatory exclusivity for our product candidates.

Our operations have been limited to organizing our company, acquiring, developing and securing our proprietary technology and identifying and obtaining preclinical data or
clinical  data  for  various  product  candidates.  These  operations  provide  a  limited  basis  for  you  to  assess  our  ability  to  continue  to  develop  our  technology,  identify  product
candidates, develop and commercialize any product candidates we are able to identify and enter into successful collaborative arrangements with other companies, as well as for
you to assess the advisability of investing in our securities. Each of these requirements will require substantial time, effort and financial resources.

Each of our product candidates will require additional preclinical or clinical development, management of preclinical, clinical and manufacturing activities, regulatory approval
in  multiple  jurisdictions,  obtaining  manufacturing  supply,  building  of  a  commercial  organization,  and  significant  marketing  efforts  before  we  generate  any  revenues  from
product sales. We are not permitted to market or promote any of our product candidates before we receive regulatory approval from the FDA or comparable foreign regulatory
authorities, and we may never receive such regulatory approval for any of our product candidates.

Pre-clinical development is highly speculative and has a high risk of failure.

Two of our current product candidates are in clinical trials, and we are evaluating the terms of license agreements for three additional pre-clinical assets. Our pre-clinical product
candidates have never been used in humans. Pre-clinical development is highly speculative and carries a high risk of failure. We can provide no assurances that pre-clinical
toxicology and/or pre-clinical activity of our product candidates will support moving any of these product candidates into clinical development. If we are unsuccessful in our
pre-clinical development efforts for any of these product candidates and they fail to reach clinical development, it would have a material adverse effect on our business and
financial condition.

Delays in clinical testing could result in increased costs to us and delay our ability to generate revenue.

Although we are planning for certain clinical trials relating to our product candidates, there can be no assurance that the FDA will accept our proposed trial designs. We may
experience delays in our clinical trials and we do not know whether planned clinical trials will begin on time, need to be redesigned, enroll patients on time or be completed on
schedule, if at all. Clinical trials can be delayed for a variety of reasons, including delays related to:

·

·

·

·

·

·

·

·

obtaining  regulatory  approval  to  commence  a
trial;

reaching agreement on acceptable terms with prospective contract research organizations, or CROs, and clinical trial sites, the terms of which can be subject to extensive
negotiation and may vary significantly among different CROs and trial sites;

obtaining institutional review board, or IRB, approval at each site;

recruiting suitable patients to participate in a trial;

clinical sites deviating from trial protocol or dropping out of a trial;

having patients complete a trial or return for post-treatment follow-up;

developing and validating companion diagnostics on a timely basis, if required;

adding new clinical trial sites; or

· manufacturing sufficient quantities of product candidate for use in clinical trials.

Patient enrollment, a significant factor in the timing of clinical trials, is affected by many factors including the size and nature of the patient population, the proximity of patients
to clinical sites, the eligibility criteria for the trial, the design of the clinical trial, competing clinical trials and clinicians’ and patients’ perceptions as to the potential advantages
of the drug being studied in relation to other available therapies, including any new drugs that may be approved for the indications we are investigating. Furthermore, we intend
to rely on CROs and clinical trial sites to ensure the proper and timely conduct of our clinical trials and we intend to have agreements governing their committed activities,
however, we will have limited influence over their actual performance.

We  could  encounter  delays  if  a  clinical  trial  is  suspended  or  terminated  by  us,  by  the  IRBs  of  the  institutions  in  which  such  trials  are  being  conducted,  by  the  Data  Safety
Monitoring Board, or DSMB, for such trial or by the FDA or other regulatory authorities. Such authorities may impose such a suspension or termination due to a number of
factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by
the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using
a drug, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial.

If we experience delays in the completion of, or termination of, any clinical trial of our product candidates, the commercial prospects of our product candidates will be harmed,
and our ability to generate product revenues from any of these product candidates will be delayed. In addition, any delays in completing our clinical trials will increase our costs,
slow down our product candidate development and approval process and jeopardize our ability to commence product sales and generate revenues. Any of these occurrences
may harm our business, financial condition and prospects significantly. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of
clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates.

We may not receive regulatory approval for our product candidates, or their approval may be further delayed, which would have a material adverse effect on our business
and financial condition.

Our product candidates and the activities associated with their development and commercialization, including their design, testing, manufacture, safety, efficacy, recordkeeping,
labeling, storage, approval, advertising, promotion, sale and distribution, are subject to comprehensive regulation by the FDA and other regulatory agencies in the US and by the
European Medicines Agency and similar regulatory authorities outside the US. Failure to obtain marketing approval for one or more of our product candidates or any future
product  candidate  will  prevent  us  from  commercializing  the  product  candidate.  We  have  not  received  approval  to  market  any  of  our  product  candidates  from  regulatory
authorities in any jurisdiction. We have only limited experience in filing and supporting the applications necessary to gain marketing approvals and expect to rely on third-party
contract  research  organizations  to  assist  us  in  this  process.  Securing  marketing  approval  requires  the  submission  of  extensive  preclinical  and  clinical  data  and  supporting
information  to  regulatory  authorities  for  each  therapeutic  indication  to  establish  the  product  candidate’s  safety  and  efficacy.  Securing  marketing  approval  also  requires  the
submission of information about the product manufacturing process to, and inspection of manufacturing facilities by, the regulatory authorities. One or more of our product
candidates or any future product candidate may not be effective, may be only moderately effective or may prove to have undesirable or unintended side effects, toxicities or
other characteristics that may preclude our obtaining marketing approval or prevent or limit commercial use. If any of our product candidates or any future product candidate
receives marketing approval, the accompanying label may limit the approved use of our drug in this way, which could limit sales of the product.

The process of obtaining marketing approvals, both in the United States and abroad, is expensive, may take many years if approval is obtained at all, and can vary substantially
based upon a variety of factors, including the type, complexity and novelty of the product candidates involved. Changes in marketing approval policies during the development
period,  changes  in  or  the  enactment  of  additional  statutes  or  regulations,  or  changes  in  regulatory  review  for  each  submitted  product  application  may  cause  delays  in  the
approval or rejection of an application. Regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may decide that
our  data  is  insufficient  for  approval  and  require  additional  preclinical  studies  or  clinical  trials.  In  addition,  varying  interpretations  of  the  data  obtained  from  preclinical  and
clinical testing could delay, limit or prevent marketing approval of a product candidate. Any marketing approval we ultimately obtain may be limited or subject to restrictions or
post-approval commitments that render the approved product not commercially viable. 

If  we  experience  delays  in  obtaining  approval  or  if  we  fail  to  obtain  approval  of  one  or  more  of  our  product  candidates  or  any  future  product  candidate,  the  commercial
prospects for our product candidates may be harmed and our ability to generate revenue will be materially impaired.

In addition, even if we were to obtain approval, regulatory authorities may approve any of our product candidates or any future product candidate for fewer or more limited
indications than we request, may not approve the price we intend to charge for our products, may grant approval contingent on the performance of costly post-marketing clinical
trials, or may approve a product candidate with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that product
candidate. Any of these scenarios could compromise the commercial prospects for one or more of our product candidates or any future product candidate.

15

 
 
   
 
 
 
 
 
 
 
 
If any of our product candidates is approved and our contract manufacturer fails to produce the product in the volumes that we require on a timely basis, or fails to comply
with stringent regulations applicable to pharmaceutical drug manufacturers, we may face delays in the commercialization of our product candidates or be unable to meet
market demand, and may lose potential revenues.

The manufacture of pharmaceutical products requires significant expertise and capital investment, including the development of advanced manufacturing techniques and process
controls, and the use of specialized processing equipment. We intend to enter into development and supply agreements with contract manufacturers for the completion of pre-
commercialization manufacturing development activities and the manufacture of commercial supplies for each of our product candidates. Any termination or disruption of our
relationships with our contract manufacturers may materially harm our business and financial condition, and frustrate any commercialization efforts for each respective product
candidate.

All  of  our  contract  manufacturers  must  comply  with  strictly  enforced  federal,  state  and  foreign  regulations,  including  cGMP  requirements  enforced  by  the  FDA  through  its
facilities inspection program, and we have little control over their compliance with these regulations. Any failure to comply with applicable regulations may result in fines and
civil penalties, suspension of production, suspension or delay in product approval, product seizure or recall, or withdrawal of product approval, and would limit the availability
of our product. Any manufacturing defect or error discovered after products have been produced and distributed could result in even more significant consequences, including
costly recall procedures, re-stocking costs, damage to our reputation and potential for product liability claims.

If the commercial manufacturers upon whom we rely to manufacture one or more of our product candidates, and any future product candidate we may in-license, fail to deliver
the  required  commercial  quantities  on  a  timely  basis  at  commercially  reasonable  prices,  we  would  likely  be  unable  to  meet  demand  for  our  products  and  we  would  lose
potential revenues.

Our approach to the discovery and development of our product candidates is unproven, and we do not know whether we will be able to develop any products of commercial
value.

Our products candidates are emerging technologies and, consequently, it is conceivable that such technologies may ultimately fail to identify commercially viable drugs to treat
human patients with cancer or other diseases.

If serious adverse or unacceptable side effects are identified during the development of one or more of our product candidates or any future product candidate, we may
need to abandon or limit our development of some of our product candidates.

If one or more of our product candidates or any future product candidate are associated with undesirable side effects in clinical trials or have characteristics that are unexpected,
we may need to abandon their development or limit development to more narrow uses or subpopulations in which the undesirable side effects or other characteristics are less
prevalent, less severe or more acceptable from a risk-benefit perspective. In our industry, many compounds that initially showed promise in early stage testing have later been
found to cause side effects that prevented further development of the compound. In the event that our clinical trials reveal a high and unacceptable severity and prevalence of
side  effects,  our  trials  could  be  suspended  or  terminated,  and  the  FDA  or  comparable  foreign  regulatory  authorities  could  order  us  to  cease  further  development  or  deny
approval of one or more of our product candidates or any future product candidate for any or all targeted indications. The FDA could also issue a letter requesting additional data
or information prior to making a final decision regarding whether or not to approve a product candidate. The number of requests for additional data or information issued by the
FDA in recent years has increased and has resulted in substantial delays in the approval of several new drugs. Undesirable side effects caused by one or more of our product
candidates or any future product candidate could also result in the inclusion of unfavorable information in our product labeling, denial of regulatory approval by the FDA or
other regulatory authorities for any or all targeted indications, and in turn prevent us from commercializing and generating revenues from the sale of that product candidate.
Drug-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial and could result in potential product liability claims.

Additionally,  if  one  or  more  of  our  product  candidates  or  any  future  product  candidate  receives  marketing  approval  and  we  or  others  later  identify  undesirable  side  effects
caused by this product, a number of potentially significant negative consequences could result, including:

·

·

·

·

regulatory authorities may require the addition of unfavorable labeling statements, specific warnings or a contraindication;

regulatory authorities may suspend or withdraw their approval of the product, or require it to be removed from the market;

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

our reputation may suffer.

16

 
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
Any of these events could prevent us from achieving or maintaining market acceptance of any of our product candidates or any future product candidate or could substantially
increase our commercialization costs and expenses, which in turn could delay or prevent us from generating significant revenues from its sale.

Even if one or more of our product candidates receives regulatory approval, it and any other products we may market will remain subject to substantial regulatory scrutiny.

One or more of our product candidates that we may license or acquire will also be subject to ongoing requirements and review of the FDA and other regulatory authorities.
These  requirements  include  labeling,  packaging,  storage,  advertising,  promotion,  record-keeping  and  submission  of  safety  and  other  post-market  information  and  reports,
registration  and  listing  requirements,  cGMP  requirements  relating  to  manufacturing,  quality  control,  quality  assurance  and  corresponding  maintenance  of  records  and
documents, requirements regarding the distribution of samples to physicians and recordkeeping of the drug.

The FDA may also impose requirements for costly post-marketing studies or clinical trials and surveillance to monitor the safety or efficacy of the product. The FDA closely
regulates  the  post-approval  marketing  and  promotion  of  drugs  to  ensure  drugs  are  marketed  only  for  the  approved  indications  and  in  accordance  with  the  provisions  of  the
approved  labeling.  The  FDA  imposes  stringent  restrictions  on  manufacturers’  communications  regarding  off-label  use  and  if  we  do  not  market  our  products  for  only  their
approved indications, we may be subject to enforcement action for off-label marketing. Violations of the FDCA relating to the promotion of prescription drugs may lead to
investigations alleging violations of federal and state health care fraud and abuse laws, as well as state consumer protection laws.

In addition, later discovery of previously unknown adverse events or other problems with our products, manufacturers or manufacturing processes, or failure to comply with
regulatory requirements, may yield various results, including:

·

·

·

·

·

·

·

·

·

·

·

·

·

·

restrictions on such products, operations, manufacturers or manufacturing processes;

restrictions on the labeling or marketing of a product;

restrictions on product distribution or use;

requirements to conduct post-marketing studies or clinical trials;

warning letters;

withdrawal of the products from the market;

refusal to approve pending applications or supplements to approved applications that we submit;

recall of products;

fines, restitution or disgorgement of profits;

suspension or withdrawal of marketing or regulatory approvals;

suspension of any ongoing clinical trials;

refusal to permit the import or export of our products;

product seizure; or

injunctions or the imposition of civil or criminal penalties.

The FDA’s policies may change, and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. If we
are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may
lose any marketing approval that we may have obtained.

17

 
 
   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We will need to obtain FDA approval of any proposed product brand names, and any failure or delay associated with such approval may adversely impact our business.

A pharmaceutical product cannot be marketed in the US or other countries until we have completed a rigorous and extensive regulatory review processes, including approval of
a brand name. Any brand names we intend to use for our product candidates will require approval from the FDA regardless of whether we have secured a formal trademark
registration from the PTO. The FDA typically conducts a review of proposed product brand names, including an evaluation of potential for confusion with other product names.
The FDA may also object to a product brand name if it believes the name inappropriately implies medical claims. If the FDA objects to any of our proposed product brand
names, we may be required to adopt an alternative brand name for our product candidates. If we adopt an alternative brand name, we would lose the benefit of our existing
trademark applications for such product candidate and may be required to expend significant additional resources in an effort to identify a suitable product brand name that
would qualify under applicable trademark laws, not infringe the existing rights of third parties and be acceptable to the FDA. We may be unable to build a successful brand
identity for a new trademark in a timely manner or at all, which would limit our ability to commercialize our product candidates.

Our current and future relationships with customers and third-party payors in the United States and elsewhere may be subject, directly or indirectly, to applicable anti-
kickback,  fraud  and  abuse,  false  claims,  transparency,  health  information  privacy  and  security  and  other  healthcare  laws  and  regulations,  which  could  expose  us  to
criminal sanctions, civil penalties, contractual damages, reputational harm, administrative burdens and diminished profits and future earnings.

Healthcare providers, physicians and third-party payors in the US and elsewhere will play a primary role in the recommendation and prescription of any product candidates for
which we obtain marketing approval. Our future arrangements with third-party payors and customers may expose us to broadly applicable fraud and abuse and other healthcare
laws  and  regulations,  including,  without  limitation,  the  federal  Anti-Kickback  Statute  and  the  federal  False  Claims  Act,  which  may  constrain  the  business  or  financial
arrangements and relationships through which we sell, market and distribute any product candidates for which we obtain marketing approval. In addition, we may be subject to
transparency  laws  and  patient  privacy  regulation  by  the  federal  and  state  governments  and  by  governments  in  foreign  jurisdictions  in  which  we  conduct  our  business.  The
applicable federal, state and foreign healthcare laws and regulations that may affect our ability to operate include, but are not necessarily limited to:

·

·

·

·

·

the federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving or providing remuneration,
directly or indirectly, in cash or in kind, to induce or reward, or in return for, either the referral of an individual for, or the purchase, order or recommendation of, any
good or service, for which payment may be made under federal and state healthcare programs, such as Medicare and Medicaid;

federal civil and criminal false claims laws and civil monetary penalty laws, including the federal False Claims Act, which impose criminal and civil penalties, including
civil  whistleblower  or qui tam  actions,  against  individuals  or  entities  for  knowingly  presenting,  or  causing  to  be  presented,  to  the  federal  government,  including  the
Medicare and Medicaid programs, claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to
the federal government; the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes criminal and civil liability for executing a
scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters;

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and their respective implementing regulations,
which impose obligations on covered healthcare providers, health plans, and healthcare clearinghouses, as well as their business associates that create, receive, maintain
or  transmit  individually  identifiable  health  information  for  or  on  behalf  of  a  covered  entity,  with  respect  to  safeguarding  the  privacy,  security  and  transmission  of
individually identifiable health information;

the federal Open Payments program, which requires manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare,
Medicaid  or  the  Children’s  Health  Insurance  Program,  with  specific  exceptions,  to  report  annually  to  the  Centers  for  Medicare  &  Medicaid  Services,  or  CMS,
information related to “payments or other transfers of value” made to physicians, which is defined to include doctors, dentists, optometrists, podiatrists and chiropractors,
and teaching hospitals and applicable manufacturers and applicable group purchasing organizations to report annually to CMS ownership and investment interests held
by  the  physicians  and  their  immediate  family  members.  Data  collection  began  on August  1,  2013  with  requirements  for  manufacturers  to  submit  reports  to  CMS  by
March 31, 2014 and 90 days after the end each subsequent calendar year. Disclosure of such information was made by CMS on a publicly available website beginning in
September 2014; and

analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which may apply to sales or marketing arrangements and claims
involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers; state and foreign laws that require pharmaceutical
companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government
or otherwise restrict payments that may be made to healthcare providers; state and foreign laws that require drug manufacturers to report information related to payments
and other transfers of value to physicians and other healthcare providers or marketing expenditures; and state and foreign laws governing the privacy and security of
health  information  in  certain  circumstances,  many  of  which  differ  from  each  other  in  significant  ways  and  often  are  not  preempted  by  HIPAA,  thus  complicating
compliance efforts.

18

 
    
 
  
  
 
 
 
 
 
 
 
 
Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations may involve substantial costs. It is possible that
governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse
or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may
be subject to significant civil, criminal and administrative penalties, including, without limitation, damages, fines, imprisonment, exclusion from participation in government
healthcare programs, such as Medicare and Medicaid, and the curtailment or restructuring of our operations, which could have a material adverse effect on our business. If any
of the physicians or other healthcare providers or entities with whom we expect to do business, including our collaborators, is found not to be in compliance with applicable
laws, it may be subject to criminal, civil or administrative sanctions, including exclusions from participation in government healthcare programs, which could also materially
affect our business.

Regulatory  approval  for  any  approved  product  is  limited  by  the  FDA  to  those  specific  indications  and  conditions  for  which  clinical  safety  and  efficacy  have  been
demonstrated.

Any regulatory approval is limited to those specific diseases and indications for which a product is deemed to be safe and effective by the FDA. In addition to the FDA approval
required  for  new  formulations,  any  new  indication  for  an  approved  product  also  requires  FDA  approval.  If  we  are  not  able  to  obtain  FDA  approval  for  any  desired  future
indications for our products, our ability to effectively market and sell our products may be reduced and our business may be adversely affected.

While  physicians  may  choose  to  prescribe  drugs  for  uses  that  are  not  described  in  the  product’s  labeling  and  for  uses  that  differ  from  those  tested  in  clinical  studies  and
approved by the regulatory authorities, our ability to promote the products is limited to those indications that are specifically approved by the FDA. These “off-label” uses are
common across medical specialties and may constitute an appropriate treatment for some patients in varied circumstances. Regulatory authorities in the US generally do not
regulate the behavior of physicians in their choice of treatments. Regulatory authorities do, however, restrict communications by pharmaceutical companies on the subject of
off-label use. If our promotional activities fail to comply with these regulations or guidelines, we may be subject to warnings from, or enforcement action by, these authorities.
In addition, our failure to follow FDA rules and guidelines relating to promotion and advertising may cause the FDA to suspend or withdraw an approved product from the
market, require a recall or institute fines, or could result in disgorgement of money, operating restrictions, injunctions or criminal prosecution, any of which could harm our
business.

We are subject to new legislation, regulatory proposals and managed care initiatives that may increase our costs of compliance and adversely affect our ability to market
our products, obtain collaborators and raise capital.

In  the  US  and  some  foreign  jurisdictions,  there  have  been  a  number  of  proposed  and  enacted  legislative  and  regulatory  changes  regarding  the  healthcare  system  that  could
prevent or delay marketing approval of one or more of our product candidates, restrict or regulate post-approval activities and affect our ability to profitably sell any of our
product candidates for which we obtain marketing approval.

Among policy makers and payors in the US and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare
costs, improving quality and expanding access. In the US, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major
legislative  initiatives.  In  March  2010,  President  Obama  signed  into  law  the  Patient  Protection  and  Affordable  Care  Act,  as  amended  by  the  Health  Care  and  Education
Affordability  Reconciliation Act,  or  collectively  the  PPACA,  a  sweeping  law  intended  to  broaden  access  to  health  insurance,  reduce  or  constrain  the  growth  of  healthcare
spending, enhance remedies against fraud and abuse, add new transparency requirements for the healthcare and health insurance industries, impose new taxes and fees on the
health industry and impose additional health policy reforms.

Among the provisions of the PPACA of importance to our potential product candidates are:

·

·

·

·

·

an  annual,  nondeductible  fee  on  any  entity  that  manufactures  or  imports  specified  branded  prescription  drugs  and  biologic  agents,  apportioned  among  these  entities
according to their market share in certain government healthcare programs;

an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 13.0% of the average manufacturer price
for branded and generic drugs, respectively;

an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 13.0% of the average manufacturer price
for branded and generic drugs, respectively;

expansion of healthcare fraud and abuse laws, including the federal False Claims Act and the federal Anti-Kickback Statute, new government investigative powers and
enhanced penalties for non-compliance;

a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% point-of-sale discounts off negotiated prices of applicable brand
drugs to eligible beneficiaries during their coverage gap period, as a condition for a manufacturer’s outpatient drugs to be covered under Medicare Part D;

19

 
  
 
 
 
  
 
 
 
 
 
 
 
 
 
 
 
·

·

·

·

·

·

extension of a manufacturer’s Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations;

expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals and by adding new
mandatory  eligibility  categories  for  certain  individuals  with  income  at  or  below  138%  of  the  federal  poverty  level,  thereby  potentially  increasing  a  manufacturer’s
Medicaid rebate liability;

expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program;

the new requirements under the federal Open Payments program and its implementing regulations;

a new requirement to annually report drug samples that manufacturers and distributors provide to physicians; and

a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for
such research.

In addition, other legislative changes have been proposed and adopted since the PPACA was enacted. These changes include aggregate reductions to Medicare payments to
providers of up to 2% per fiscal year that started in 2013. On March 1, 2013, the President signed an executive order implementing the 2% Medicare payment reductions, and
on April 1, 2013, these reductions went into effect. In January 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, which, among other things,
reduced Medicare payments to several providers and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.
These  new  laws  may  result  in  additional  reductions  in  Medicare  and  other  healthcare  funding,  which  could  have  a  material  adverse  effect  on  customers  for  our  drugs,  if
approved, and, accordingly, our financial operations.

We  expect  that  the  PPACA,  as  well  as  other  healthcare  reform  measures  that  may  be  adopted  in  the  future,  may  result  in  more  rigorous  coverage  criteria  and  in  additional
downward pressure on the price that we receive for any approved drug. Any reduction in reimbursement from Medicare or other government healthcare programs may result in
a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate
revenue, attain profitability or commercialize our drugs.

Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for drugs. We cannot be sure whether
additional legislative changes will be enacted, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing
approvals  of  our  product  candidates,  if  any,  may  be.  In  addition,  increased  scrutiny  by  the  US  Congress  of  the  FDA’s  approval  process  may  significantly  delay  or  prevent
marketing approval, as well as subject us to more stringent product labeling and post-marketing testing and other requirements.

Public concern regarding the safety of drug products could delay or limit our ability to obtain regulatory approval, result in the inclusion of unfavorable information in our
labeling, or require us to undertake other activities that may entail additional costs.

In light of widely publicized events concerning the safety risk of certain drug products, the FDA, members of the US Congress, the Government Accountability Office, medical
professionals and the general public have raised concerns about potential drug safety issues. These events have resulted in the withdrawal of drug products, revisions to drug
labeling  that  further  limit  use  of  the  drug  products  and  the  establishment  of  risk  management  programs.  The  Food  and  Drug Administration Amendments Act  of  2007,  or
FDAAA, grants significant expanded authority to the FDA, much of which is aimed at improving the safety of drug products before and after approval. In particular, the new
law authorizes the FDA to, among other things, require post-approval studies and clinical trials, mandate changes to drug labeling to reflect new safety information and require
risk evaluation and mitigation strategies for certain drugs, including certain currently approved drugs. It also significantly expands the federal government’s clinical trial registry
and results databank, which we expect will result in significantly increased government oversight of clinical trials. Under the FDAAA, companies that violate these and other
provisions of the new law are subject to substantial civil monetary penalties, among other regulatory, civil and criminal penalties. The increased attention to drug safety issues
may result in a more cautious approach by the FDA in its review of data from our clinical trials. Data from clinical trials may receive greater scrutiny, particularly with respect
to  safety,  which  may  make  the  FDA  or  other  regulatory  authorities  more  likely  to  require  additional  preclinical  studies  or  clinical  trials.  If  the  FDA  requires  us  to  conduct
additional preclinical studies or clinical trials prior to approving any of our product candidates, our ability to obtain approval of this product candidate will be delayed. If the
FDA requires us to provide additional clinical or preclinical data following the approval of any of our product candidates, the indications for which this product candidate is
approved  may  be  limited  or  there  may  be  specific  warnings  or  limitations  on  dosing,  and  our  efforts  to  commercialize  our  product  candidates  may  be  otherwise  adversely
impacted.

20

 
  
 
 
 
 
 
 
  
 
   
 
 
 
 
If we experience delays or difficulties in the enrollment of patients in clinical trials, our receipt of necessary regulatory approvals could be delayed or prevented.

We may not be able to initiate or continue clinical trials for one or more of our product candidates if we are unable to locate and enroll a sufficient number of eligible patients to
participate in these trials as required by the FDA or similar regulatory authorities outside the United States. Some of our competitors have ongoing clinical trials for product
candidates that treat the same indications as our product candidates, and patients who would otherwise be eligible for our clinical trials may instead enroll in clinical trials of our
competitors’ product candidates. Available therapies for the indications we are pursuing can also affect enrollment in our clinical trials. Patient enrollment is affected by other
factors including, but not necessarily limited to:

·

·

·

·

·

·

·

the severity of the disease under investigation;

the eligibility criteria for the study in question;

the perceived risks and benefits of the product candidate under study;

the efforts to facilitate timely enrollment in clinical trials;

the patient referral practices of physicians;

the ability to monitor patients adequately during and after treatment; and

the proximity and availability of clinical trial sites for prospective patients.

Our  inability  to  enroll  a  sufficient  number  of  patients  for  our  clinical  trials  would  result  in  significant  delays  and  could  require  us  to  abandon  one  or  more  clinical  trials
altogether. Enrollment delays in our clinical trials may result in increased development costs for our product candidate or future product candidates, which would cause the value
of our company to decline and limit our ability to obtain additional financing.

Our  product  candidates  are  in  scientific  areas  of  intense  competition  from  many  large  pharmaceutical  and  biotechnology  companies,  many  of  which  are  significantly
further along in development or are already on the market with competing products. We expect competition for our product candidates will intensify, and new products may
emerge that provide different or better therapeutic alternatives for our targeted indications.

The biotechnology and pharmaceutical industries are subject to rapid and intense technological change. We face, and will continue to face, competition in the development and
marketing of our product candidates from academic institutions, government agencies, research institutions and biotechnology and pharmaceutical companies. There can be no
assurance  that  developments  by  others  will  not  render  one  or  more  of  our  product  candidates  obsolete  or  noncompetitive.  Furthermore,  new  developments,  including  the
development of other drug technologies and methods of preventing the incidence of disease, occur in the pharmaceutical industry at a rapid pace. These developments may
render one or more of our product candidates obsolete or noncompetitive.

Our product candidates will compete with other product candidates with similar indications. Please refer to Item 1. “Business — Competition”. 

Competitors may seek  to  develop  alternative  formulations  that  do  not  directly  infringe  on  our  in-licensed  patent  rights.  The  commercial  opportunity  for  one  or  more  of  our
product candidates could be significantly harmed if competitors are able to develop alternative formulations outside the scope of our in-licensed patents. Compared to us, many
of our potential competitors have substantially greater:

·

·

·

·

·

capital resources;

development resources, including personnel and technology;

clinical trial experience;

regulatory experience;

expertise in prosecution of intellectual property rights; and

· manufacturing, distribution and sales and marketing experience.

As  a  result  of  these  factors,  our  competitors  may  obtain  regulatory  approval  of  their  products  more  rapidly  than  we  are  able  to  or  may  obtain  patent  protection  or  other
intellectual property rights that limit our ability to develop or commercialize one or more of our product candidates. Our competitors may also develop drugs that are more
effective, safe, useful and less costly than ours and may be more successful than us in manufacturing and marketing their products.

Our commercial success depends upon us attaining significant market acceptance of our product candidates, if approved for sale, among physicians, patients, healthcare
payors and major operators of cancer and other clinics.

Even if we obtain regulatory approval for one or more of our product candidates, the product may not gain market acceptance among physicians, health care payors, patients
and the medical  community,  which  are  critical  to  commercial  success.  Market  acceptance  of  any  product  candidate  for  which  we  receive  approval  depends  on  a  number  of
factors, including, but not necessarily limited to:

·

·

·

·

·

·

·

·

·

·

·

·

the efficacy and safety as demonstrated in clinical trials;

the timing of market introduction of such product candidate as well as competitive products;

the clinical indications for which the drug is approved;

acceptance by physicians, major operators of cancer clinics and patients of the drug as a safe and effective treatment;

the safety of such product candidate seen in a broader patient group, including its use outside the approved indications;

the availability, cost and potential advantages of alternative treatments, including less expensive generic drugs;

the availability of adequate reimbursement and pricing by third-party payors and government authorities;

the relative convenience and ease of administration of the product candidate for clinical practices;

the product labeling or product insert required by the FDA or regulatory authority in other countries;

the approval, availability, market acceptance and reimbursement for a companion diagnostic, if any;

the prevalence and severity of adverse side effects; and

the effectiveness of our sales and marketing efforts.

If any product candidate that we develop does not provide a treatment regimen that is as beneficial as, or is not perceived as being as beneficial as, the current standard of care or
otherwise does not provide patient benefit, that product candidate, if approved for commercial sale by the FDA or other regulatory authorities, likely will not achieve market
acceptance. Our ability to effectively promote and sell any approved products will also depend on pricing and cost-effectiveness, including our ability to produce a product at a
competitive price and our ability to obtain sufficient third-party coverage or reimbursement. If any product candidate is approved but does not achieve an adequate level of
acceptance by physicians, patients and third-party payors, our ability to generate revenues from that product would be substantially reduced. In addition, our efforts to educate
the medical community and third-party payors on the benefits of our product candidates may require significant resources, may be constrained by FDA rules and policies on
product promotion, and may never be successful.

If approved, our product candidates will face competition from less expensive generic products of competitors, and, if we are unable to differentiate the benefits of our
product candidates over these less expensive alternatives, we may never generate meaningful product revenues.

Generic therapies are typically sold at lower prices than branded therapies and are generally preferred by hospital formularies and managed care providers of health services. We
anticipate that, if approved, our product candidates will face increasing competition in the form of generic versions of branded products of competitors that have lost or will lose
their  patent  exclusivity.  In  the  future,  we  may  face  additional  competition  from  a  generic  form  when  the  patents  covering  it  begin  to  expire,  or  earlier  if  the  patents  are
successfully  challenged.  If  we  are  unable  to  demonstrate  to  physicians  and  payers  that  the  key  differentiating  features  of  our  product  candidates  translate  to  overall  clinical
benefit or lower cost of care, we may not be able to compete with generic alternatives.

Reimbursement may be limited or unavailable in certain market segments for our product candidates, which could make it difficult for us to sell our products profitably.

There is significant uncertainty related to the third-party coverage and reimbursement of newly approved drugs. Such third-party payors include government health programs
such as Medicare, managed care providers, private health insurers and other organizations. We intend to seek approval to market our product candidates in the US, the EU and
other  selected  foreign  jurisdictions.  Market  acceptance  and  sales  of  our  product  candidates  in  both  domestic  and  international  markets  will  depend  significantly  on  the
availability of adequate coverage and reimbursement from third-party payors for any of our product candidates and may be affected by existing and future health care reform
measures. Government and other third-party payors are increasingly attempting to contain healthcare costs by limiting both coverage and the level of reimbursement for new
drugs and, as a result, they may not cover or provide adequate payment for our product candidates. These payors may conclude that our product candidates are less safe, less
effective or less cost-effective than existing or future introduced products, and third-party payors may not approve our product candidates for coverage and reimbursement or
may cease providing coverage and reimbursement for these product candidates.

22

 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
   
 
 
 
 
 
 
 
Obtaining coverage and reimbursement approval for a product from a government or other third-party payor is a time consuming and costly process that could require us to
provide to the payor supporting scientific, clinical and cost-effectiveness data for the use of our products. We may not be able to provide data sufficient to gain acceptance with
respect to coverage and reimbursement. If reimbursement of our future products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, we may
be unable to achieve or sustain profitability.

In some foreign countries, particularly in the EU, the pricing of prescription pharmaceuticals is subject to governmental control. In these countries, pricing negotiations with
governmental  authorities  can  take  considerable  time  after  the  receipt  of  marketing  approval  for  a  product  candidate.  To  obtain  reimbursement  or  pricing  approval  in  some
countries, we may be required to conduct additional clinical trials that compare the cost-effectiveness of our product candidates to other available therapies. If reimbursement of
our product candidates is unavailable or limited in scope or amount in a particular country, or if pricing is set at unsatisfactory levels, we may be unable to achieve or sustain
profitability of our products in such country.

If we are unable to establish sales, marketing and distribution capabilities or to enter into agreements with third parties to market and sell our product candidates, we may
not be successful in commercializing our product candidates if and when they are approved.

We  currently  do  not  have  a  marketing  or  sales  organization  for  the  marketing,  sales  and  distribution  of  pharmaceutical  products.  In  order  to  commercialize  any  product
candidate that receives marketing approval, we would need to build marketing, sales, distribution, managerial and other non-technical capabilities or make arrangements with
third parties to perform these services, and we may not be successful in doing so. In the event of successful development and regulatory approval of one or more of our product
candidates or any future product candidate, we expect to build a targeted specialist sales force to market or co-promote the product. There are risks involved with establishing
our own sales, marketing and distribution capabilities. For example, recruiting and training a sales force is expensive and time consuming and could delay any product launch. If
the commercial launch of a product candidate for which we recruit a sales force and establish marketing capabilities is delayed or does not occur for any reason, we would have
prematurely or unnecessarily incurred these commercialization expenses. This may be costly, and our investment would be lost if we cannot retain or reposition our sales and
marketing personnel.        

Factors that may inhibit our efforts to commercialize our products on our own include, but are not necessarily limited to:

·

·

·

·

our inability to recruit, train and retain adequate numbers of effective sales and marketing personnel;

the inability of sales personnel to obtain access to physicians or persuade adequate numbers of physicians to prescribe any future products;

the lack of complementary or other products to be offered by sales personnel, which may put us at a competitive disadvantage from the perspective of sales efficiency
relative to companies with more extensive product lines; and

unforeseen costs and expenses associated with creating an independent sales and marketing organization.

As an alternative to establishing our own sales force, we may choose to partner with third parties that have well-established direct sales forces to sell, market and distribute our
products.

We rely, and expect to continue to rely, on third parties to conduct our preclinical studies and clinical trials, and those third parties may not perform satisfactorily, including
failing to meet deadlines for the completion of such trials or complying with applicable regulatory requirements.

We rely on third-party contract research organizations and site management organizations to conduct some of our preclinical studies and all of our clinical trials for our product
candidates and for any future product candidate. We expect to continue to rely on third parties, such as contract research organizations, site management organizations, clinical
data management organizations, medical institutions and clinical investigators, to conduct some of our preclinical studies and all of our clinical trials. The agreements with these
third parties might terminate for a variety of reasons, including a failure to perform by the third parties. If we need to enter into alternative arrangements, that could delay our
product development activities.

23

 
  
 
 
 
   
 
 
 
 
 
 
 
   
 
 
Our  reliance  on  these  third  parties  for  research  and  development  activities  will  reduce  our  control  over  these  activities  but  will  not  relieve  us  of  our  responsibilities.  For
example, we will remain responsible for ensuring that each of our preclinical studies and clinical trials are conducted in accordance with the general investigational plan and
protocols for the trial and for ensuring that our preclinical studies are conducted in accordance with good laboratory practice (GLP) as appropriate. Moreover, the FDA requires
us to comply with standards, commonly referred to as good clinical practices (GCPs) for conducting, recording and reporting the results of clinical trials to assure that data and
reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. Regulatory authorities enforce these requirements
through periodic inspections of trial sponsors, clinical investigators and trial sites. If we or any of our clinical research organizations fail to comply with applicable GCPs, the
clinical data generated in our clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require us to perform additional clinical
trials before approving our marketing applications. We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any
of our clinical trials complies with GCP regulations. In addition, our clinical trials must be conducted with product produced under cGMP regulations. Our failure to comply
with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process. We also are required to register ongoing clinical trials and post
the results of completed clinical trials on a government-sponsored database, ClinicalTrials.gov, within specified timeframes. Failure to do so can result in fines, adverse publicity
and civil and criminal sanctions.

The third parties with whom we have contracted to help perform our preclinical studies or clinical trials may also have relationships with other entities, some of which may be
our  competitors.  If  these  third  parties  do  not  successfully  carry  out  their  contractual  duties,  meet  expected  deadlines  or  conduct  our  preclinical  studies  or  clinical  trials  in
accordance with regulatory requirements or our stated protocols, we will not be able to obtain, or may be delayed in obtaining, marketing approvals for our product candidates
and will not be able to, or may be delayed in our efforts to, successfully commercialize our product candidates.

If any of our relationships with these third-party contract research organizations or site management organizations terminates, we may not be able to enter into arrangements
with  alternative  contract  research  organizations  or  site  management  organizations  or  to  do  so  on  commercially  reasonable  terms.  Switching  or  adding  additional  contract
research organizations or site management organizations involves additional cost and requires management time and focus. In addition, there is a natural transition period when
a  new  contract  research  organization  or  site  management  organization  commences  work. As  a  result,  delays  could  occur,  which  could  compromise  our  ability  to  meet  our
desired  development  timelines.  Though  we  carefully  manage  our  relationships  with  our  contract  research  organizations  or  site  management  organizations,  there  can  be  no
assurance that we will not encounter similar challenges or delays in the future.

We contract with third parties for the manufacture of our product candidates for preclinical and clinical testing and expect to continue to do so for commercialization. This
reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or any future product candidate or such quantities at an
acceptable cost, which could delay, prevent or impair our development or commercialization efforts.

We do not have any manufacturing facilities or personnel. We rely, and expect to continue to rely, on third parties for the manufacture of our product candidates for preclinical
and clinical testing, as well as for commercial manufacture if any of our product candidates receive marketing approval. This reliance on third parties increases the risk that we
will not have sufficient quantities of our product candidates or any future product candidate or such quantities at an acceptable cost or quality, which could delay, prevent or
impair our development or commercialization efforts.

We also expect to rely on third-party manufacturers or third-party collaborators for the manufacture of commercial supply of any product candidates for which our collaborators
or we obtain marketing approval. We may be unable to establish any agreements with third-party manufacturers or to do so on acceptable terms. Even if we are able to establish
agreements with third-party manufacturers, reliance on third-party manufacturers entails additional risks, including, but not necessarily limited to:

·

·

reliance on the third party for regulatory compliance and quality assurance;

the possible breach of the manufacturing agreement by the third party;

· manufacturing delays if our third-party manufacturers give greater priority to the supply of other products over our product candidates or otherwise do not satisfactorily

perform according to the terms of the agreement between us;

·

·

the possible misappropriation of our proprietary information, including our trade secrets and know-how; and

the possible termination or nonrenewal of the agreement by the third party at a time that is costly or inconvenient for us.

We rely on our third-party manufacturers to produce or purchase from third-party suppliers the materials and equipment necessary to produce our product candidates for our
pre-clinical and clinical trials. There are a limited number of suppliers for raw materials and equipment that we use (or that are used on our behalf) to manufacture our drugs,
and  there  may  be  a  need  to  assess  alternate  suppliers  to  prevent  a  possible  disruption  of  the  manufacture  of  the  materials  and  equipment  necessary  to  produce  our  product
candidates for our pre-clinical and clinical trials, and if approved, ultimately for commercial sale. We do not have any control over the process or timing of the acquisition of
these raw materials or equipment by our third-party manufacturers. Any significant delay in the supply of a product candidate, or the raw material components thereof, for an
ongoing  pre-clinical  or  clinical  trial  due  to  the  need  to  replace  a  third-party  manufacturer  could  considerably  delay  completion  of  our  pre-clinical  or  clinical  trials,  product
testing  and  potential  regulatory  approval  of  our  product  candidates.  If  our  manufacturers  or  we  are  unable  to  purchase  these  raw  materials  or  equipment  after  regulatory
approval has been obtained for our product candidates, the commercial launch of our product candidates would be delayed or there would be a shortage in supply, which would
impair our ability to generate revenues from the sale of our product candidates.

24

 
 
 
 
   
 
 
 
 
 
 
 
 
 
 
 
The facilities used by our contract manufacturers to manufacture our product candidates must be approved by the FDA pursuant to inspections that will be conducted after we
submit  an  NDA  to  the  FDA.  We  do  not  control  the  manufacturing  process  of,  and  are  completely  dependent  on,  our  contract  manufacturers  for  compliance  with  cGMP
regulations  for  manufacture  of  our  product  candidates.  Third-party  manufacturers  may  not  be  able  to  comply  with  the  cGMP  regulations  or  similar  regulatory  requirements
outside  the  United  States.  Our  failure,  or  the  failure  of  our  third-party  manufacturers,  to  comply  with  applicable  regulations  could  result  in  sanctions  being  imposed  on  us,
including  clinical  holds,  fines,  injunctions,  civil  penalties,  delays,  suspension  or  withdrawal  of  approvals,  license  revocation,  seizures  or  recalls  of  product  candidates  or
products, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of our products.

One or more of the product candidates that we may develop may compete with other product candidates and products for access to manufacturing facilities. There are a limited
number of manufacturers that operate under cGMP regulations and that might be capable of manufacturing for us. Any performance failure on the part of our existing or future
manufacturers could delay clinical development or marketing approval. We do not currently have arrangements in place for redundant supply or a second source for bulk drug
substance.  If  our  current  contract  manufacturers  cannot  perform  as  agreed,  we  may  be  required  to  replace  such  manufacturers.  We  may  incur  added  costs  and  delays  in
identifying  and  qualifying  any  replacement  manufacturers.  The  DEA  restricts  the  importation  of  a  controlled  substance  finished  drug  product  when  the  same  substance  is
commercially available in the United States, which could reduce the number of potential alternative manufacturers for one or more of our product candidates.

Our current and anticipated future dependence upon others for the manufacture of our product candidates or products may adversely affect our future profit margins and our
ability to commercialize any products that receive marketing approval on a timely and competitive basis.

We also expect to rely on other third parties to store and distribute drug supplies for our clinical trials. 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, producing additional losses and depriving us of potential product revenue.

We rely on clinical data and results obtained by third parties that could ultimately prove to be inaccurate or unreliable.

As part of our strategy to mitigate development risk, we seek to develop product candidates with validated mechanisms of action and we utilize biomarkers to assess potential
clinical efficacy early in the development process. This strategy necessarily relies upon clinical data and other results obtained by third parties that may ultimately prove to be
inaccurate or unreliable. Further, such clinical data and results may be based on products or product candidates that are significantly different from our product candidates or
any future product candidate. If the third-party data and results we rely upon prove to be inaccurate, unreliable or not applicable to our product candidates or future product
candidate, we could make inaccurate assumptions and conclusions about our product candidates and our research and development efforts could be compromised.

If we breach any of the agreements under which we license rights to one or more of product candidates from others, we could lose the ability to continue to develop and
commercialize such product candidate.

Because we have in-licensed the rights to all of our product candidates from COH, and in the future will continue to in-license from additional third parties, if there is any
dispute  between  us  and  our  licensor  regarding  our  rights  under  our  license  agreement,  our  ability  to  develop  and  commercialize  these  product  candidates  may  be  adversely
affected. Any uncured, material breach under our license agreement could result in our loss of exclusive rights to our product candidate and may lead to a complete termination
of our related product development efforts.

We may not be able to manage our business effectively if we are unable to attract and retain key personnel.

We  may  not  be  able  to  attract  or  retain  qualified  management  and  commercial,  scientific  and  clinical  personnel  in  the  future  due  to  the  intense  competition  for  qualified
personnel among biotechnology, pharmaceutical and other businesses. If we are not able to attract and retain necessary personnel to accomplish our business objectives, we may
experience  constraints  that  will  significantly  impede  the  achievement  of  our  development  objectives,  our  ability  to  raise  additional  capital  and  our  ability  to  implement  our
business strategy.

Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could have a material
adverse effect on our business.

We  are  exposed  to  the  risk  of  employee  fraud  or  other  misconduct.  Misconduct  by  employees  could  include  intentional  failures  to  comply  with  FDA  regulations,  provide
accurate information to the FDA, comply with manufacturing standards we have established, comply with federal and state health-care fraud and abuse laws and regulations,
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, 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. Employee misconduct could
also  involve  the  improper  use  of  information  obtained  in  the  course  of  clinical  trials,  which  could  result  in  regulatory  sanctions  and  serious  harm  to  our  reputation.  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 be in compliance with such 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 and results of operations, including the imposition of
significant fines or other sanctions.

25

 
  
 
   
 
 
 
 
 
 
 
 
 
 
 
 
We face potential product liability exposure, and if successful claims are brought against us, we may incur substantial liability for one or more of our product candidates or
a future product candidate we may license or acquire and may have to limit their commercialization.

The use of one or more of our product candidates and any future product candidate we may license or acquire in clinical trials and the sale of any products for which we obtain
marketing approval expose us to the risk of product liability claims. For example, we may be sued if any product we develop allegedly causes injury or is found to be otherwise
unsuitable during clinical testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a
failure to warn of dangers inherent in the product, negligence, strict liability or a breach of warranties. Product liability claims might be brought against us by consumers, health
care  providers  or  others  using,  administering  or  selling  our  products.  If  we  cannot  successfully  defend  ourselves  against  these  claims,  we  will  incur  substantial  liabilities.
Regardless of merit or eventual outcome, liability claims may result in:

·

·

·

·

·

·

·

·

·

·

withdrawal of clinical trial participants;

termination of clinical trial sites or entire trial programs;

decreased demand for any product candidates or products that we may develop;

initiation of investigations by regulators;

impairment of our business reputation;

costs of related litigation;

substantial monetary awards to patients or other claimants;

loss of revenues;

reduced resources of our management to pursue our business strategy; and

the inability to commercialize our product candidate or future product candidates.

We will obtain limited product liability insurance coverage for any and all of our upcoming clinical trials. However, our insurance coverage may not reimburse us or may not be
sufficient to reimburse us for any expenses or losses we may suffer. Moreover, insurance coverage is becoming increasingly expensive, and, in the future, we may not be able to
maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to liability. When needed we intend to expand our insurance coverage
to  include  the  sale  of  commercial  products  if  we  obtain  marketing  approval  for  one  or  more  of  our  product  candidates  in  development,  but  we  may  be  unable  to  obtain
commercially reasonable product liability insurance for any products approved for marketing. On occasion, large judgments have been awarded in class action lawsuits based on
drugs that had unanticipated side effects. A successful product liability claim or series of claims brought against us could cause our stock price to fall and, if judgments exceed
our insurance coverage, could decrease our cash and adversely affect our business.

Our future growth depends on our ability to identify and acquire or in-license products and if we do not successfully identify  and  acquire  or  in-license  related  product
candidates or integrate them into our operations, we may have limited growth opportunities.

An important part of our business strategy is to continue to develop a pipeline of product candidates by acquiring or in-licensing products, businesses or technologies that we
believe  are  a  strategic  fit  with  our  focus  on  novel  combinations  of  immuno-oncology  antibodies  and  small  molecule  kinase  inhibitors.  Future  in-licenses  or  acquisitions,
however, may entail numerous operational and financial risks, including, but not necessarily limited to:

·

·

·

exposure to unknown liabilities;

disruption of our business and diversion of our management’s time and attention to develop acquired products or technologies;

difficulty or inability to secure financing to fund development activities for such acquired or in-licensed technologies in the current economic environment;

26

 
   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
·

·

·

·

·

·

incurrence of substantial debt or dilutive issuances of securities to pay for acquisitions;

higher than expected acquisition and integration costs;

increased amortization expenses;

difficulty and cost in combining the operations and personnel of any acquired businesses with our operations and personnel;

impairment of relationships with key suppliers or customers of any acquired businesses due to changes in management and ownership; and

inability to retain key employees of any acquired businesses.

We  have  limited  resources  to  identify  and  execute  the  acquisition  or  in-licensing  of  third-party  products,  businesses  and  technologies  and  integrate  them  into  our  current
infrastructure.  In  particular,  we  may  compete  with  larger  pharmaceutical  companies  and  other  competitors  in  our  efforts  to  establish  new  collaborations  and  in-licensing
opportunities. These competitors likely will have access to greater financial resources than us and may have greater expertise in identifying and evaluating new opportunities.
Moreover, we may devote resources to potential acquisitions or in-licensing opportunities that are never completed, or we may fail to realize the anticipated benefits of such
efforts.

We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more
profitable or for which there is a greater likelihood of success.

Because we have limited financial and managerial resources, we focus on research programs and product candidates that we identify for specific indications. As a result, we
may forego or delay pursuit of opportunities with other product candidates or for other indications that later prove to have greater commercial potential. Our resource allocation
decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development
programs and product candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target
market for a particular product candidate, we may relinquish valuable rights to that product candidate through 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.

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 harm 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. Although we believe that the safety procedures for handling and disposing of these materials comply with the standards prescribed
by these laws and regulations, we cannot eliminate the risk of accidental 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 for failure to comply with such laws and regulations.

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, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may
be asserted against us in connection with our storage or disposal of biological, hazardous or radioactive materials.

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. Our failure to comply with these laws and regulations also may result in substantial fines, penalties or
other sanctions.

Our business and operations would suffer in the event of system failures.

Despite  the  implementation  of  security  measures,  our  internal  computer  systems  are  vulnerable  to  damage  from  computer  viruses,  unauthorized  access,  natural  disasters,
terrorism, war and telecommunication and electrical failures. Any system failure, accident or security breach that causes interruptions in our operations could result in a material
disruption of our drug development programs. For example, the loss of clinical trial data from completed clinical trials for one or more of our product conducts could result in
delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach results in a loss
or damage to our data or applications, or inappropriate disclosure of confidential or proprietary information, we may incur liability and the further development of one or more
of our product candidates may be delayed.

We are partly reliant on the City of Hope National Medical Center for research and development and early clinical testing of certain of our product candidates.

A substantial portion of our research and development has been conducted by COH pursuant to a sponsored research agreement executed between Mustang and COH in March
2015. We have limited control over the nature or timing of COH’s research and limited visibility into its day-to-day activities. Our future success is heavily dependent on the
results of research and development efforts of Dr. Stephen Forman and his laboratory team at COH.

CAR-T is a new approach to cancer treatment that presents significant challenges.

We  have  concentrated  our  research  and  development  efforts  on  CAR-T  technology,  and  our  future  success  is  highly  dependent  on  the  successful  development  of  T  cell
immunotherapies in general and our CAR-T technology and product candidates in particular. Because CAR-T is a new approach to cancer immunotherapy and cancer treatment
generally, developing and commercializing our product candidates subjects us to a number of challenges, including, but not necessarily limited to:

·

·

·

·

·

·

·

·

·

obtaining regulatory approval from the FDA and other regulatory authorities that may have very limited experience with the commercial development of genetically
modified T cell therapies for cancer;

developing and deploying consistent and reliable processes for engineering a patient’s T cells ex vivo and infusing the engineered T cells back into the patient;

conditioning patients with chemotherapy in conjunction with delivering each of our products, which may increase the risk of adverse side effects of our products;

educating medical personnel regarding the potential side effect profile of each of our products;

developing processes for the safe administration of these products, including long-term follow-up for all patients who receive our product candidates;

sourcing clinical and, if approved, commercial supplies for the materials used to manufacture and process our product candidates;

developing a manufacturing process and distribution network with a cost of goods that allows for an attractive return on investment;

establishing sales and marketing capabilities after obtaining any regulatory approval to gain market acceptance, and obtaining adequate coverage, reimbursement and
pricing by third-party payors and government authorities; and

developing therapies for types of cancers beyond those addressed by our current product candidates.

Product  candidates,  even  if  successfully  developed  and  commercialized,  may  be  effective  only  in  combatting  certain  specific  types  of  cancer,  and  the  market  for  drugs
designed to combat such cancer type(s) may be small and unprofitable.

There are many different types of cancer, and a treatment that is effective against one type of cancer may not be effective against another. CAR-T or other technologies we
pursue may only be effective in combatting specific types of cancer but not others. Even if one or more of our products proves to be an effective treatment against a given type
of cancer, the number of patients suffering from such cancer may be small, in which case potential sales from a drug designed to combat such cancer would be limited.

Risks Related to Intellectual Property

If we are unable to obtain and maintain patent protection for our technology and products or if the scope of the patent protection obtained is not sufficiently broad, our
competitors  could  develop  and  commercialize  technology  and  products  similar  or  identical  to  ours,  and  our  ability  to  successfully  commercialize  our  technology  and
products may be impaired.

Our commercial success will depend in part on obtaining and maintaining patent protection and trade secret protection in the US and other countries with respect to our product
candidates or any future product candidate that we may license or acquire and the methods we use to manufacture them, as well as successfully defending these patents and trade
secrets against third-party challenges. We seek to protect our proprietary position by filing patent applications in the United States and abroad related to our product candidates.
We will only be able to protect our technologies from unauthorized use by third parties to the extent that valid and enforceable patents or trade secrets cover them.

The patent prosecution process is expensive and time-consuming, and we may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost
or in a timely manner. It is also possible that we will fail to identify any patentable aspects of our research and development output, and, if we do, an opportunity to obtain
patent protection may have passed. If our licensors or we fail to obtain or maintain patent protection or trade secret protection for one or more of product candidates or any
future product candidate we may license or acquire, third parties may be able to access our proprietary information, which could impair our ability to compete in the market and
adversely  affect  our  ability  to  generate  revenues  and  achieve  profitability.  Moreover,  should  we  enter  into  other  collaborations  we  may  be  required  to  consult  with  or  cede
control  to  collaborators  regarding  the  prosecution,  maintenance  and  enforcement  of  licensed  patents.  Therefore,  these  patents  and  applications  may  not  be  prosecuted  and
enforced in a manner consistent with the best interests of our business.

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions and has in recent years been the
subject of much litigation. In addition, no consistent policy regarding the breadth of claims allowed in pharmaceutical or biotechnology patents has emerged to date in the US.
The patent situation outside the US is even more uncertain. The laws of foreign countries may not protect our rights to the same extent as the laws of the US. For example,
European patent law restricts the patentability of methods of treatment of the human body more than US law does. Publications of discoveries in the scientific literature often lag
behind the actual discoveries, and patent applications in the US and other jurisdictions are typically not published until 18 months after a first filing, if at all. Therefore, we
cannot know with certainty whether we or our licensors were the first to make the inventions claimed in patents or pending patent applications that we own or licensed, or that
we or our licensors were the first to file for patent protection of such inventions. In the event that a third party has also filed a US patent application relating to our product
candidates or a similar invention, depending upon the priority dates claimed by the competing parties, we may have to participate in interference proceedings declared by the
PTO to determine priority of invention in the US. The costs of these proceedings could be substantial and it is possible that our efforts to establish priority of invention would be
unsuccessful, resulting in a material adverse effect on our US patent position. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights
are highly uncertain. Our pending and future patent applications may not result in patents being issued which protect our technology or products, in whole or in part, or which
effectively prevent others from commercializing competitive technologies and products. Changes in either the patent laws or interpretation of the patent laws in the US and
other countries may diminish the value of our patents or narrow the scope of our patent protection. For example, the federal courts of the US have taken an increasingly dim
view of the patent eligibility of certain subject matter, such as naturally occurring nucleic acid sequences, amino acid sequences and certain methods of utilizing same, which
include their detection in a biological sample and diagnostic conclusions arising from their detection. Such subject matter, which had long been a staple of the biotechnology
and biopharmaceutical industry to protect their discoveries, is now considered, with few exceptions, ineligible in the first place for protection under the patent laws of the US.
Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in our patents or in those licensed from a third-party.

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 United States patent law. These include provisions that affect the way patent applications are prosecuted and may also affect patent litigation. The PTO recently
developed new 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 inventor-to-file provisions, only became effective on March 16, 2013. Accordingly, 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.

Moreover, we may be subject to a third-party preissuance submission of prior art to the PTO, or become involved in opposition, derivation, reexamination, inter partes review,
post-grant review or interference proceedings challenging our patent rights or the patent rights of others. An adverse determination in any such submission, patent office trial,
proceeding or litigation could reduce the scope of, render unenforceable, or invalidate, our patent rights, allow third parties to commercialize our technology or products and
compete directly with us, without payment to us, or result in our inability to manufacture or commercialize products without infringing third-party patent rights. In addition, if
the breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or
commercialize current or future product candidates.

Even if our patent applications issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors from competing with us
or  otherwise  provide  us  with  any  competitive  advantage.  Our  competitors  may  be  able  to  circumvent  our  owned  or  licensed  patents  by  developing  similar  or  alternative
technologies or products in a non-infringing manner.

The issuance of a patent does not foreclose challenges to its inventorship, scope, validity or enforceability. Therefore, our owned and licensed patents may be challenged in the
courts or patent offices in the United States and abroad. Such challenges may result in loss of exclusivity or in patent claims being narrowed, invalidated or held unenforceable,
in whole or in part, which could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent
protection of our technology and products. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting
such product candidates might expire before or shortly after such product candidates are commercialized. As a result, our owned and licensed patent portfolio may not provide
us with sufficient rights to exclude others from commercializing products similar or identical to ours.

29

 
  
 
 
   
 
 
 
 
 
We depend on our licensors for the maintenance and enforcement of intellectual property covering certain of our product candidates and have limited control, if any, over
the  amount  or  timing  of  resources  that  our  licensors  devote  on  our  behalf,  or  whether  any  financial  difficulties  experienced  by  our  licensors  could  result  in  their
unwillingness or inability to secure, maintain and enforce patents protecting certain of our product candidates.

We depend on our licensors to protect the proprietary rights covering our product candidates and we have limited, if any, control over the amount or timing of resources that
they devote on our behalf, or the priority they place on, maintaining patent rights and prosecuting patent applications to our advantage.

Our  licensors,  depending  on  the  patent  or  application,  are  responsible  for  maintaining  issued  patents  and  prosecuting  patent  applications.  We  cannot  be  sure  that  they  will
perform as required. Should they decide they no longer want to maintain any of the patents licensed to us, they are required to afford us the opportunity to do so at our expense.
If our licensors do not perform, and if we do not assume the maintenance of the licensed patents in sufficient time to make required payments or filings with the appropriate
governmental  agencies,  we  risk  losing  the  benefit  of  all  or  some  of  those  patent  rights.  Moreover,  our  licensors  may  experience  serious  difficulties  related  to  their  overall
business or financial stability, and they may be unwilling or unable to continue to expend the financial resources required to maintain and prosecute these patents and patent
applications.  While  we  intend  to  take  actions  reasonably  necessary  to  enforce  our  patent  rights,  we  depend,  in  part,  on  our  licensors  to  protect  a  substantial  portion  of  our
proprietary rights.

Our licensors may also be notified of alleged infringement and be sued for infringement of third-party patents or other proprietary rights. We may have limited, if any, control or
involvement over the defense of these claims, and our licensors could be subject to injunctions and temporary or permanent exclusionary orders in the US or other countries.
Our  licensors  are  not  obligated  to  defend  or  assist  in  our  defense  against  third-party  claims  of  infringement.  We  have  limited,  if  any,  control  over  the  amount  or  timing  of
resources, if any, that our licensors devote on our behalf or the priority they place on defense of such third-party claims of infringement.

Because of the uncertainty inherent in any patent or other litigation involving proprietary rights, we or our licensors may not be successful in defending claims of intellectual
property infringement alleged by third parties, which could have a material adverse effect on our results of operations. Regardless of the outcome of any litigation, defending the
litigation may be expensive, time-consuming and distracting to management.

Because it is difficult and costly to protect our proprietary rights, we may not be able to ensure their protection.

The degree of future protection for our proprietary rights is uncertain, because legal means afford only limited protection and may not adequately protect our rights or permit us
to gain or keep our competitive advantage. For example:

·

·

·

·

·

·

·

our licensors might not have been the first to make the inventions covered by each of our pending patent applications and issued patents;

our licensors might not have been the first to file patent applications for these inventions;

others may independently develop similar or alternative technologies or duplicate our product candidates or any future product candidate technologies;

it is possible that none of the pending patent applications licensed to us will result in issued patents;

the issued patents covering our product candidates or any future product candidate may not provide a basis for market exclusivity for active products, may not provide us
with any competitive advantages, or may be challenged by third parties;

we may not develop additional proprietary technologies that are patentable; or

patents of others may have an adverse effect on our business.

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

Competitors may infringe our issued patents or other intellectual property. To counter infringement or unauthorized use, we may be required to file one or more actions for
patent infringement, which can be expensive and time consuming. Any claims we assert against accused infringers could provoke these parties to assert counterclaims against
us alleging that we infringe their patents. In addition, in a patent infringement proceeding, a court may decide that a patent of ours is invalid or unenforceable, in whole or in
part, construe the patent’s claims narrowly or 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 proceeding could put one or more of our patents at risk of being invalidated, rendered unenforceable, or interpreted narrowly.

30

 
  
 
 
 
 
 
 
   
 
 
 
 
 
 
 
 
 
 
 
If we are sued for infringing intellectual property rights of third parties, it will be costly and time consuming, and an unfavorable outcome in any litigation would harm our
business.

Our ability to develop, manufacture, market and sell one or more of our product candidates or any future product candidate that we may license or acquire depends upon our
ability to avoid infringing the proprietary rights of third parties. Numerous US and foreign issued patents and pending patent applications, which are owned by third parties,
exist in the general fields of fully human immuno-oncology targeted antibodies and cover the use of numerous compounds and formulations in our targeted markets. Because of
the  uncertainty  inherent  in  any  patent  or  other  litigation  involving  proprietary  rights,  we  and  our  licensors  may  not  be  successful  in  defending  intellectual  property  claims
asserted by third parties, which could have a material adverse effect on our results of operations. Regardless of the outcome of any litigation, defending the litigation may be
expensive, time-consuming and distracting to management. In addition, because patent applications can take many years to issue, there may be currently pending applications
that are unknown to us, which may later result in issued patents that one or more of our product candidates may infringe. There could also be existing patents of which we are
not aware that one or more of our product candidates may infringe, even if only inadvertently.

There is a substantial amount of litigation involving patent and other intellectual property rights in the biotechnology and biopharmaceutical industries generally. If a third party
claims that we infringe their patents or misappropriated their technology, we could face a number of issues, including:

·

·

·

·

·

infringement and other intellectual property claims which, with or without merit, can be expensive and time consuming to litigate and can divert management’s attention
from our core business;

substantial damages for past infringement which we may have to pay if a court decides that our product infringes a competitor’s patent;

a court prohibiting us from selling or licensing our product unless the patent holder licenses the patent to us, which it would not be required to do;

if a license is available from a patent holder, we may have to pay substantial royalties or grant cross licenses to our patents; and

redesigning our processes so they do not infringe, which may not be possible or could require substantial funds and time.

Intellectual property litigation could cause us to spend substantial resources and distract our personnel from their normal responsibilities.

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses, and could distract our
technical and management personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions or other interim
proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common
stock.  Such  litigation  or  proceedings  could  substantially  increase  our  operating  losses  and  reduce  the  resources  available  for  development  activities  or  any  future  sales,
marketing or distribution activities. We may not have sufficient financial or other resources to conduct such litigation or proceedings adequately. Some of our competitors may
be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources. Uncertainties resulting from the initiation
and continuation of patent litigation or other proceedings could compromise our ability to compete in the marketplace.

We may need to license certain intellectual property from third parties, and such licenses may not be available or may not be available on commercially reasonable terms.

A  third  party  may  hold  intellectual  property,  including  patent  rights  that  are  important  or  necessary  to  the  development  and  commercialization  of  our  products.  It  may  be
necessary for us to use the patented or proprietary technology of third parties to commercialize our products, in which case we would be required to obtain a license from these
third parties on commercially reasonable terms, or our business could be harmed, possibly materially.

If we fail to comply with our obligations in our intellectual property licenses and funding arrangements with third parties, we could lose rights that are important to our
business.

We  are  currently  a  party  to  a  license  agreement  with  the  City  of  Hope.  In  the  future,  we  may  become  party  to  licenses  that  are  important  for  product  development  and
commercialization. If we fail to comply with our obligations under current or future license and funding agreements, our counterparties may have the right to terminate these
agreements, in which event we might not be able to develop, manufacture or market any product or utilize any technology that is covered by these agreements or may face other
penalties under the agreements. Such an occurrence could materially and adversely affect the value of a product candidate being developed under any such agreement or could
restrict our drug discovery activities. Termination of these agreements or reduction or elimination of our rights under these agreements may result in our having to negotiate new
or reinstated agreements with less favorable terms, or cause us to lose our rights under these agreements, including our rights to important intellectual property or technology.

31

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

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

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

In addition to seeking patent protection for our product candidates or any future product candidate, we also rely on trade secrets, including unpatented know-how, technology
and  other  proprietary  information,  to  maintain  our  competitive  position,  particularly  where  we  do  not  believe  patent  protection  is  appropriate  or  obtainable.  However,  trade
secrets are difficult to protect. We limit disclosure of such trade secrets where possible but we also seek to protect these trade secrets, in part, by entering into non-disclosure and
confidentiality  agreements  with  parties  who  do  have  access  to  them,  such  as  our  employees,  our  licensors,  corporate  collaborators,  outside  scientific  collaborators,  contract
manufacturers,  consultants,  advisors  and  other  third  parties.  We  also  enter  into  confidentiality  and  invention  or  patent  assignment  agreements  with  our  employees  and
consultants. Despite these efforts, any of these parties may breach the agreements and may unintentionally or willfully disclose our proprietary information, including our trade
secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult,
expensive and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade
secrets. Moreover, if any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them, or those to
whom they communicate it, from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a
competitor, our competitive position would be harmed.

Risks Related to Our Finances and Capital Requirements

We have incurred significant losses since our inception. We expect to incur losses for the foreseeable future, and may never achieve or maintain profitability.

We  are  an  emerging  growth  company  with  a  limited  operating  history.  We  have  focused  primarily  on  in-licensing  and  developing  our  product  candidates,  with  the  goal  of
supporting regulatory approval for these product candidates. We have incurred losses since our inception in March 2015, and have an accumulated deficit of $17.1 million as of
December 31, 2016. We expect to continue to incur significant operating losses for the foreseeable future. We also do not anticipate that we will achieve profitability for a period
of  time  after  generating  material  revenues,  if  ever.  If  we  are  unable  to  generate  revenues,  we  will  not  become  profitable  and  may  be  unable  to  continue  operations  without
continued funding.

Because of the numerous risks and uncertainties associated with developing pharmaceutical products, we are unable to predict the timing or amount of increased expenses or
when or if, we will be able to achieve profitability. Our net losses may fluctuate significantly from quarter to quarter and year to year. We anticipate that our expenses will
increase substantially if:

·

·

·

·

·

·

·

·

one or more of our product candidates are approved for commercial sale, due to our ability to establish the necessary commercial infrastructure to launch this product
candidate without substantial delays, including hiring sales and marketing personnel and contracting with third parties for warehousing, distribution, cash collection and
related commercial activities;

we are required by the FDA or foreign regulatory authorities, to perform studies in addition to those currently expected;

there are any delays in completing our clinical trials or the development of any of our product candidates;

we execute other collaborative, licensing or similar arrangements and the timing of payments we may make or receive under these arrangements;

there are variations in the level of expenses related to our future development programs;

there are any product liability or intellectual property infringement lawsuits in which we may become involved;

there are any regulatory developments affecting product candidates of our competitors; and

one or more of our product candidates receives regulatory approval.

32

 
  
 
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our ability to become profitable depends upon our ability to generate revenue. To date, we have not generated any revenue from our development stage products, and we do not
know when, or if, we will generate any revenue. Our ability to generate revenue depends on a number of factors, including, but not limited to, our ability to:

·

obtain regulatory approval for one or more of our product candidates, or any future product candidate that we may license or acquire;

· manufacture commercial quantities of one or more of our product candidates or any future product candidate, if approved, at acceptable cost levels; and

·

develop a commercial organization and the supporting infrastructure required to successfully market and sell one or more of our product candidates or any future product
candidate, if approved.

Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would
depress  the  value  of  our  company  and  could  impair  our  ability  to  raise  capital,  expand  our  business,  maintain  our  research  and  development  efforts,  diversify  our  product
offerings or even continue our operations. A decline in the value of our company could also cause you to lose all or part of your investment.

Our short operating history makes it difficult to evaluate our business and prospects.

We were incorporated in March 2015 and have only been conducting operations with respect to our product candidates since March 2015. Our operations to date have been
limited  to  preclinical  operations  and  the  in-licensing  of  our  product  candidates.  We  have  not  yet  demonstrated  an  ability  to  successfully  complete  clinical  trials,  obtain
regulatory  approvals,  manufacture  a  commercial  scale  product,  or  arrange  for  a  third  party  to  do  so  on  our  behalf,  or  conduct  sales  and  marketing  activities  necessary  for
successful product commercialization. Consequently, any predictions about our future performance may not be as accurate as they could be if we had a history of successfully
developing and commercializing pharmaceutical products.

In addition, as a young business, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown factors. We will need to expand our
capabilities to support commercial activities. We may not be successful in adding such capabilities.

We expect our financial condition and operating results to continue to fluctuate significantly from quarter to quarter and year to year due to a variety of factors, many of which
are beyond our control. Accordingly, you should not rely upon the results of any past quarterly period as an indication of future operating performance.

We do not have any products that are approved for commercial sale and therefore do not expect to generate any revenues from product sales in the foreseeable future, if
ever.

We have not generated any product related revenues to date, and do not expect to generate any such revenues for at least the next several years, if at all. To obtain revenues from
sales of our product candidates, we must succeed, either alone or with third parties, in developing, obtaining regulatory approval for, manufacturing and marketing products
with commercial potential. We may never succeed in these activities, and we may not generate sufficient revenues to continue our business operations or achieve profitability.

We will require substantial additional funding which may not be available to us on acceptable terms, or at all. If we fail to raise the necessary additional capital, we may be
unable to complete the development and commercialization of our product candidates, or continue our development programs.

Our operations have consumed substantial amounts of cash since inception. We expect to significantly increase our spending to advance the preclinical and clinical development
of  our  product  candidates  and  launch  and  commercialize  any  product  candidates  for  which  we  receive  regulatory  approval,  including  building  our  own  commercial
organizations to address certain markets. We will require additional capital for the further development and commercialization of our product candidates, as well as to fund our
other operating expenses and capital expenditures. As of December 31, 2016 we had $27.5 million in cash. We cannot provide any assurance that we will be able to raise funds
to complete the development of our product.

We  cannot  be  certain  that  additional  funding  will  be  available  on  acceptable  terms,  or  at  all.  If  we  are  unable  to  raise  additional  capital  in  sufficient  amounts  or  on  terms
acceptable to us we may have to significantly delay, scale back or discontinue the development or commercialization of one or more of our product candidates. We may also
seek collaborators for one or more of our current or future product candidates at an earlier stage than otherwise would be desirable or on terms that are less favorable than might
otherwise be available. Any of these events could significantly harm our business, financial condition and prospects.

Our future funding requirements will depend on many factors, including, but not limited to:

·

the timing, design and conduct of, and results from, pre-clinical and clinical trials for our product candidates;

33

 
  
 
 
 
 
  
 
 
 
 
 
  
 
 
 
 
 
 
 
·

·

·

·

·

·

·

·

·

the potential for delays in our efforts to seek regulatory approval for our product candidates, and any costs associated with such delays;

the costs of establishing a commercial organization to sell, market and distribute our product candidates;

the rate of progress and costs of our efforts to prepare for the submission of an NDA for any product candidates that we may in-license or acquire in the future, and the
potential that we may need to conduct additional clinical trials to support applications for regulatory approval;

the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights associated with our product candidates, including any
such costs we may be required to expend if our licensors are unwilling or unable to do so;

the cost and timing of securing sufficient supplies of our product candidates from our contract manufacturers for clinical trials and in preparation for commercialization;

the effect of competing technological and market developments;

the terms and timing of any collaborative, licensing, co-promotion or other arrangements that we may establish;

if one or more of our product candidates are approved, the potential that we may be required to file a lawsuit to defend our patent rights or regulatory exclusivities from
challenges by companies seeking to market generic versions of one or more of our product candidates; and

the success of the commercialization of one or more of our product candidates.

Future capital requirements will also depend on the extent to which we acquire or invest in additional complementary businesses, products and technologies, but we currently
have no commitments or agreements relating to any of these types of transactions.

In order to carry out our business plan and implement our strategy, we anticipate that we will need to obtain additional financing from time to time and may choose to raise
additional funds through strategic collaborations, licensing arrangements, public or private equity or debt financing, bank lines of credit, asset sales, government grants, or other
arrangements. We cannot be sure that any additional funding, if needed, will be available on terms favorable to us or at all. Furthermore, any additional equity or equity-related
financing  may  be  dilutive  to  our  stockholders,  and  debt  or  equity  financing,  if  available,  may  subject  us  to  restrictive  covenants  and  significant  interest  costs.  If  we  obtain
funding through a strategic collaboration or licensing arrangement, we may be required to relinquish our rights to certain of our product candidates or marketing territories.

Our inability to raise capital when needed would harm our business, financial condition and results of operations, and could cause our stock value to decline or require that we
wind down our operations altogether.

Raising additional capital may cause dilution to our existing stockholders, restrict our operations or require us to relinquish proprietary rights.

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our cash needs through a combination of equity offerings, debt financings, grants
and  license  and  development  agreements  in  connection  with  any  collaborations.  To  the  extent  that  we  raise  additional  capital  through  the  sale  of  equity  or  convertible  debt
securities,  your  ownership  interest  will  be  diluted,  and  the  terms  of  these  securities  may  include  liquidation  or  other  preferences  that  adversely  affect  your  rights  as  a
stockholder.  Debt  financing  and  preferred  equity  financing,  if  available,  may  involve  agreements  that  include  covenants  limiting  or  restricting  our  ability  to  take  specific
actions, such as incurring additional debt, making capital expenditures or declaring dividends.

If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable
rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise
additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization
efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

We will continue to incur significant increased costs as a result of operating as a public company, and our management will be required to devote substantial time to new
compliance initiatives.

We intend to become a listed and traded public company. As a public company, we will incur significant legal, accounting and other expenses under the Sarbanes-Oxley Act of
2002, or the Sarbanes-Oxley Act, as well as rules subsequently implemented by the SEC, and the rules of any stock exchange on which we become listed. These rules impose
various  requirements  on  public  companies,  including  requiring  establishment  and  maintenance  of  effective  disclosure  and  financial  controls  and  appropriate  corporate
governance practices. Our management and other personnel have devoted and will continue to devote a substantial amount of time to these compliance initiatives. Moreover,
these  rules  and  regulations  increase  our  legal  and  financial  compliance  costs  and  make  some  activities  more  time-consuming  and  costly.  For  example,  these  rules  and
regulations  make  it  more  difficult  and  more  expensive  for  us  to  obtain  director  and  officer  liability  insurance,  and  we  may  be  required  to  accept  reduced  policy  limits  and
coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified persons to serve on
our board of directors, our board committees or as executive officers.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective internal controls for financial reporting and disclosure controls and procedures. As a result, we
are  required  to  periodically  perform  an  evaluation  of  our  internal  controls  over  financial  reporting  to  allow  management  to  report  on  the  effectiveness  of  those  controls,  as
required by Section 404 of the Sarbanes-Oxley Act. Additionally, our independent auditors are required to perform a similar evaluation and report on the effectiveness of our
internal controls over financial reporting. These efforts to comply with Section 404 and related regulations have required, and continue to require, the commitment of significant
financial and managerial resources. While we anticipate maintaining the integrity of our internal controls over financial reporting and all other aspects of Section 404, we cannot
be certain that a material weakness will not be identified when we test the effectiveness of our control systems in the future. If a material weakness is identified, we could be
subject to sanctions or investigations by the SEC or other regulatory authorities, which would require additional financial and management resources, costly litigation or a loss
of public confidence in our internal controls, which could have an adverse effect on the market price of our stock.

Compliance  with  the  Sarbanes-Oxley  Act  of  2002  will  require  substantial  financial  and  management  resources  and  may  increase  the  time  and  costs  of  completing  an
acquisition. 

A business that we identify as a potential acquisition target may not be in compliance with the provisions of the Sarbanes-Oxley Act regarding the adequacy of internal controls.
The development of the internal controls of any such entity to achieve compliance with the Sarbanes-Oxley Act may increase the time and costs necessary to complete any such
acquisition. Furthermore, any failure to implement required new or improved controls, or difficulties encountered in the implementation of adequate controls over our financial
processes and reporting in the future, could harm our operating results or cause us to fail to meet our reporting obligations. Inferior internal controls could also cause investors
to lose confidence in our reported financial information, which could have a negative effect on the trading price of our securities. 

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

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups (JOBS) Act. We will remain an “emerging growth company” for up to five years.
However, if our non-convertible debt issued within a three-year period or revenues exceeds $1 billion, or the market value of our equity shares that are held by non-affiliates
exceeds $700 million on the last day of the second fiscal quarter of any given fiscal year, we would cease to be an emerging growth company as of the following fiscal year. As
an  emerging  growth  company,  we  are  not  being  required  to  comply  with  the  auditor  attestation  requirements  of  Section  404  of  the  Sarbanes-Oxley Act,  we  have  reduced
disclosure  obligations  regarding  executive  compensation  in  our  periodic  reports  and  proxy  statements,  and  we  are  exempt  from  the  requirements  of  holding  a  nonbinding
advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

Further,  Section  102(b)(1)  of  the  JOBS Act  exempts  emerging  growth  companies  from  being  required  to  comply  with  new  or  revised  financial  accounting  standards  until
private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange
Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period
and comply with the requirements that apply to non-emerging growth companies, but any such an election to opt out is irrevocable. We have elected not to opt out of such
extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging
growth company, will not adopt the new or revised standard until the time private companies are required to adopt the new or revised standard. This may make comparison of
our  financial  statements  with  another  public  company,  which  is  neither  an  emerging  growth  company  nor  an  emerging  growth  company,  which  has  opted  out  of  using  the
extended transition period, difficult or impossible because of the potential differences in accounting standards used. 

Our results of operations and liquidity needs could be materially negatively affected by market fluctuations and economic downturn.

Our results of operations could be materially negatively affected by economic conditions generally, both in the US and elsewhere around the world. Continuing concerns over
inflation, energy costs, geopolitical issues, the availability and cost of credit, the US mortgage market and residential real estate market in the US have contributed to increased
volatility  and  diminished  expectations  for  the  economy  and  the  markets  going  forward.  These  factors,  combined  with  volatile  oil  prices,  declining  business  and  consumer
confidence and increased unemployment, have precipitated an economic recession and fears of a possible depression. Domestic and international equity markets continue to
experience heightened volatility and turmoil. These events and the continuing market upheavals may have an adverse effect on us. In the event of a continuing market downturn,
our results of operations could be adversely affected by those factors in many ways, including making it more difficult for us to raise funds if necessary, and our stock price may
further decline.

Our ability to use our pre-change NOLs and other pre-change tax attributes to offset post-change taxable income or taxes may be subject to limitation.

We may, from time to time, carry net operating loss carryforwards (“NOLs”) as deferred tax assets on our balance sheet.  Under Sections 382 and 383 of the Internal Revenue
Code of 1986, as amended, if a corporation undergoes an “ownership change” (generally defined as a greater than 50-percentage- point cumulative change (by value) in the
equity ownership of certain stockholders over a rolling three-year period), the corporation’s ability to use its pre-change NOLs and other pre-change tax attributes to offset its
post-change taxable income or taxes may be limited. We may experience ownership changes in the future as a result of shifts in our stock ownership, some of which changes
are outside our control. As a result, our ability to use our pre-change NOLs and other pre-change tax attributes to offset post-change taxable income or taxes may be subject to
limitation.

Risks Relating to Securities Markets and Investment in Our Stock

Our stock may be subject to substantial price and volume fluctuations due to a number of factors, many of which are beyond our control and may prevent our stockholders
from reselling our common stock at a profit.

The  market  prices  for  securities  of  biotechnology  and  pharmaceutical  companies  have  historically  been  highly  volatile,  and  the  market  has  from  time  to  time  experienced
significant price and volume fluctuations that are unrelated to the operating performance of particular companies.

Once listed and trading, the market price of our common stock is likely to be highly volatile and may fluctuate substantially due to many factors, including:

·

announcements  concerning  the  progress  of  our  efforts  to  obtain  regulatory  approval  for  and  commercialize  our  product  candidates  or  any  future  product  candidate,
including  any  requests  we  receive  from  the  FDA  for  additional  studies  or  data  that  result  in  delays  in  obtaining  regulatory  approval  or  launching  these  product
candidates, if approved;

· market conditions in the pharmaceutical and biotechnology sectors or the economy as a whole;

·

·

·

·

·

·

·

·

·

·

·

price and volume fluctuations in the overall stock market;

the failure of one or more of our product candidates or any future product candidate, if approved, to achieve commercial success;

announcements of the introduction of new products by us or our competitors;

developments concerning product development results or intellectual property rights of others;

litigation or public concern about the safety of our potential products;

actual fluctuations in our quarterly operating results, and concerns by investors that such fluctuations may occur in the future;

deviations in our operating results from the estimates of securities analysts or other analyst comments;

additions or departures of key personnel;

health care reform legislation, including measures directed at controlling the pricing of pharmaceutical products, and third-party coverage and reimbursement policies;

developments concerning current or future strategic collaborations; and

discussion of us or our stock price by the financial and scientific press and in online investor communities.

Fortress controls a voting majority of our common stock.

Pursuant to the terms of the Class A Preferred Stock held by Fortress, Fortress is entitled to cast, for each share of Class A Preferred held by Fortress, the number of votes that is
equal to one and one-tenth (1.1) times a fraction, the numerator of which is the sum of (A) the shares of outstanding common stock and (B) the whole shares of Common Stock
into  which  the  shares  of  outstanding  Class A  Common  Stock  and  the  Class A  Preferred  Stock  are  convertible  and  the  denominator  of  which  is  the  number  of  shares  of
outstanding Class A Preferred Stock. Accordingly, Fortress is able to control or significantly influence all matters requiring approval by our stockholders, including the election
of directors and the approval of mergers or other business combination transactions. The interests of Fortress may not always coincide with the interests of other stockholders,
and Fortress may take actions that advance its own interests and are contrary to the desires of our other stockholders. Moreover, this concentration of voting power may delay,
prevent or deter a change in control of us even when such a change may be in the best interests of all stockholders, could deprive our stockholders of an opportunity to receive a
premium for their common stock as part of a sale of Mustang or our assets, and might affect the prevailing market price of our common stock.

Fortress has the right to receive a significant grant of shares of our common stock annually which will result in the dilution of your holdings of common stock upon each
grant, which could reduce their value. City of Hope has anti-dilution protection that could result in the dilution of your holding.

Under the terms of the Second Amended and Restated Founders Agreement (See Item 7. Certain Relationships and Related Transactions, and Director Independence), which
became effective July 22, 2016, Fortress will receive a grant of shares of our common stock equal to two and one-half percent (2.5%) of the gross amount of any equity or debt
financing. Additionally, the Class A Preferred Stock, as a class, will receive an annual dividend on March 13 th, payable in shares of Common Stock in an amount equal to two
and  one-half  percent  (2.5%)  of  our  fully-diluted  outstanding  capital  stock  as  of  the  business  day  immediately  prior  to  March  13th  of  such  year.  Fortress  currently  owns  all
outstanding shares of Class A Preferred Stock. These share issuances to Fortress and any other holder of Class A Preferred Stock will dilute your holdings in our common stock
and, if the value of Mustang has not grown proportionately over the prior year, would result in a reduction in the value of your shares. The Second Amended and Restated
Founders Agreement has a term of 15 years and renews automatically for subsequent one-year periods unless terminated by Fortress or upon a Change in Control (as defined in
the Second Amended and Restated Founders Agreement).

The  Class A  Common  Stock  held  by  the  City  of  Hope  has  anti-dilution  protection  that  gives  them  the  right  to  additional  shares  of  stock  under  certain  circumstances.  The
amount of shares received by COH will vary depending on the triggering event. If any shares are required to be issued to COH, your holdings in our common stock will be
diluted and result in a reduction in the value of your shares.

We might have received better terms from unaffiliated third parties than the terms we receive in our agreements with Fortress.

The agreements we have entered into with Fortress include a Management Services Agreement and the Founders Agreement. While we believe the terms of these agreements
are reasonable, they might not reflect terms that would have resulted from arm’s-length negotiations between unaffiliated third parties. The terms of the agreements relate to,
among other things, payment of a royalty on product sales and the provision of employment and transition services. We might have received better terms from third parties
because, among other things, third parties might have competed with each other to win our business.

The  dual  roles  of  our  officers  and  directors  who  also  serve  in  similar  roles  with  Fortress  could  create  a  conflict  of  interest  and  will  require  careful  monitoring  by  our
independent directors. 

We share some directors with Fortress, and in addition, under the Management Services Agreement, we will also share some officers with Fortress.  This could create conflicts
of interest between the two companies in the future.  While we believe that the Founders Agreement and the Management Services Agreement were negotiated by independent
parties  on  both  sides  on  arm’s  length  terms,  and  the  fiduciary  duties  of  both  parties  were  thereby  satisfied,  in  the  future  situations  may  arise  under  the  operation  of  both
agreements  that  may  create  a  conflict  of  interest.    We  will  have  to  be  diligent  to  ensure  that  any  such  situation  is  resolved  by  independent  parties.    In  particular,  under  the
Management Services Agreement, Fortress and its affiliates are free to pursue opportunities which could potentially be of interest to Mustang, and they are not required to notify
Mustang prior to pursuing such opportunities. Any such conflict of interest or pursuit by Fortress of a corporate opportunity independent of Mustang could expose us to claims
by our investors and creditors and could harm our results of operations.

We may become involved in securities class action litigation that could divert management’s attention and harm our business.

The stock markets have from time to time experienced significant price and volume fluctuations that have affected the market prices for the common stock of biotechnology and
pharmaceutical  companies.  These  broad  market  fluctuations  may  cause  the  market  price  of  our  stock  to  decline.  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  biotechnology  and  biopharmaceutical
companies have experienced significant stock price volatility in recent years. We may become involved in this type of litigation in the future. Litigation often is expensive and
diverts management’s attention and resources, which could adversely affect our business.

Legal Proceedings

Otherwise as disclosed below, we are not involved in any litigation that we believe could have a material adverse effect on our financial position or results of operations. There
is  no  action,  suit,  proceeding,  inquiry  or  investigation  before  or  by  any  court,  public  board,  government  agency,  self-regulatory  organization  or  body  pending  or,  to  the
knowledge of our executive officers, threatened against or affecting our company or our officers or directors in their capacities as such.

On January 15, 2016, Dr. Winson Tang (“Plaintiff”) filed a Complaint against the Company in the Superior Court of the State of California, County of Los Angeles.  Winson
Tang v. Lindsay Rosenwald et al, Case No. BC607346.  As amended, the complaint alleges that Dr. Tang was a third-party beneficiary of the Company's Exclusive License
Agreement with COH and should be declared the owner of 15% of the Company's outstanding shares.   After the Company and other defendants demurred, the Court sustained
the  demurrer  and  dismissed  all  claims  without  prejudice  on  September  13,  2016.    Dr.  Tang  filed  his  second  amended  complaint  on  October  11,  2016,  and  the  court  again
sustained the demurrer without prejudice, except for a claim for declaratory relief against the Company.  Subsequently, Dr. Tang agreed to narrow his claims and drop certain
defendants from the case.  Dr. Tang filed his third amended complaint on January 17, 2017, alleging one claim for declaratory relief against the Company and two claims for
breach of contract against certain other Defendants.  Defendants filed their answer on February 23, 2017, denying Tan has any rights to recovery. The parties are proceeding
with discovery, and the case is set for trial on November 6, 2017. 

As  of  December  31,  2016,  the  Company  has  not  accrued  any  losses  in  connection  with  this  litigation  as  the  Company  believes  that  Plaintiff's  claims  are  without  merit  and
intends to vigorously defend this lawsuit.  Even in the event of an adverse determination, Fortress and the Company intend to satisfy any judgment from sources other than
newly issued shares of the Company to prevent dilution.

Securities

Market information

 PART II

There is no established public trading market in our common stock. Our securities are not listed for trading on any national securities exchange nor are bid or asked quotations
reported in any over-the-counter quotation service.

Equity Compensation Plans

We expect that in the future we will file a registration statement on Form S-8 under the Securities Act registering the common stock issued, issuable or reserved for issuance
under our 2016 Plan. That registration statement will become effective immediately upon filing, and shares covered by that registration statement will thereupon be eligible for
sale in the public markets, subject to grant of the underlying awards, vesting provisions and Rule 144 limitations applicable to our affiliates.

Holders

As of December 31, 2016 there were 18.7 million shares of capital stock outstanding, including vested warrants, which includes 1.0 million shares of Class A Common Stock
outstanding,  250,000  shares  of  Class A  Preferred  Stock  outstanding,  and  15.1  million  shares  of  common  stock  outstanding,  which  were  held  by  approximately  488  record
stockholders.

Dividends

We have never paid cash dividends on any of our capital stock and currently intend to retain our future earnings, if any, to fund the development and growth of our business.

Stock Not Registered Under the Securities Act; Rule 144 Eligibility

Our common stock has not been registered under the Securities Act. Accordingly, the shares of common stock issued and outstanding may not be resold absent registration
under the Securities Act and applicable state securities laws or an available exemption thereunder.

Rule 144

Shares of our common stock that are restricted securities will be eligible for resale in compliance with Rule 144 (“Rule 144”) or Rule 701 (“Rule 701”) of the Securities Act,
subject to the requirements described below. “Restricted Securities,” as defined under Rule 144, were issued and sold by us in reliance on exemptions from the registration
requirements of the Securities Act. These shares may be sold in the public market only if registered or if they qualify for an exemption from registration, such as Rule 144 or
Rule 701. Below is a summary of the requirements for sales of our common stock pursuant to Rule 144, as in effect on the date of this Form 10-K.

Affiliates

Affiliates will be able to sell their shares under Rule 144 beginning 90 days after the effectiveness of our Form 10, subject to all other requirements of Rule 144. In general,
under Rule 144, an affiliate would be entitled to sell within any three-month period a number of shares that does not exceed one percent of the number of shares of our common
stock then outstanding. Sales under Rule 144 are also subject to manner of sale provisions and notice requirements and to the availability of current public information about us.

Persons  who  may  be  deemed  to  be  our  affiliates  generally  include  individuals  or  entities  that  control,  or  are  controlled  by,  or  are  under  common  control  with,  us  and  may
include our directors and officers, as well as our significant stockholders.

Non-Affiliates

For a person who has not been deemed to have been one of our affiliates at any time during the 90 days preceding a sale, sales of our shares of common stock held longer than
six months, but less than one year, will be subject only to the current public information requirement and can be sold under Rule 144 beginning 90 days after the effectiveness
of our Form 10. A person who is not deemed to have been one of our affiliates at any time during the 90 days preceding a sale, and who has beneficially owned the shares
proposed to be sold for at least one year, is entitled to sell the shares without complying with the manner of sale, public information, volume limitation or notice provisions of
Rule 144 upon the effectiveness of our Form 10.

Rule 701

Rule 701 under the Securities Act, as in effect on the date of this Form 10-K, permits resale of shares in reliance upon Rule 144 but without compliance with certain restrictions
of Rule 144, including the holding period requirement. Most of our employees, executive officers, directors or consultants who purchased shares under a written compensatory
plan or contract may be entitled to rely on the resale provisions of Rule 701, but all holders of Rule 701 shares are required to wait until 90 days after the effective date of our
Form 10 before selling their shares under Rule 701.

Securities Authorized for Issuance under Equity Compensation Plans

Subject to adjustment as provided in the 2016 Plan, the aggregate number of shares of our common stock reserved and available for issuance pursuant to awards granted under
the 2016 Plan is 2,000,000. 

Recent Sales of Unregistered Securities.

In September 2016, we entered into a Placement Agent Agreement with National Securities, Inc. (“NSC”) relating to a private placement of Common Stock (“NSC Private
Placement”).  Pursuant  to  the  Placement Agent Agreement,  we  agreed  to  pay  the  Placement Agent  a  cash  fee  of  10%  of  the  gross  proceeds  from  the  offering  and  granted  a
warrant exercisable for shares of Common Stock equal to 10% of the aggregate number of shares of Common Stock sold in the offering (the “Placement Agent Warrants”). In
addition, we adopted a form of unit purchase agreement for investors. The Common Stock and Warrants were sold in units, with each unit consisting of 10,000 shares of our
Common Stock, and Warrants exercisable for 2,500 shares of Common Stock at an exercise price of $8.50 per share. The purchase price was $65,000 per Unit. The warrants
have a five-year term and are only exercisable for cash.

As of December 31, 2016, we received gross proceeds of $39.1 million, before expenses, in connection with the NSC Private Placement, NSC received a fee of $3.9 million or
approximately  10%  of  the  gross  proceeds  as  well  as  warrants  equal  to  10%  of  the  common  shares  issued.  We  issued  6,014,874  unregistered  shares  of  Common  Stock  and
1,503,717 warrants in connection with this transaction. In addition, the placement agent received 601,486 warrants or approximately 10% of the shares issued. The shares of
Common Stock and Warrants were issued under an exemption from the Securities Act, provided by Regulation D promulgated thereunder.

In October 2016, we issued a warrant to NSC Biotech Venture Fund I to purchase 138,462 shares of Common Stock. The per share exercise price of the warrant is $0.0001 or
par value of our shares and expires 10 years after the issuance date. The warrant was granted in connection the $3.6 million outstanding note to NSC Biotech Venture Fund I
which we repaid in December of 2016.

39

 
 
 
 
 
 
 
 
   
 
 
 
 
  
 
 
 
 
 
In the final closing of the NSC Private Placement in January 2017, we issued 8,536,774 shares of common shares and warrants to purchase 2,134,193 shares of Common Stock
to accredited investors, for aggregate gross proceeds of $55.5 million. Pursuant to the terms of the private placement, we paid a cash fee of $5.5 million and issued a warrant to
purchase 853,667 shares of common shares to the NSC, who acted as the placement agent.

We expect to use the net proceeds from the above transaction primarily for general corporate purposes, which may include financing our growth, developing new or existing
product candidates, and funding capital expenditures, acquisitions and investments.

Description of Registrant’s Securities.

The following description summarizes the material terms of Mustang capital stock as of the date of this Form 10-K. Because it is only a summary, it does not contain all the
information that may be important to you. For a complete description of our capital stock, you should refer to our certificate of incorporation and our bylaws.

The  authorized  capital  stock  of  Mustang  consists  of  (i)  50,000,000  shares  of  Common  Stock,  of  which  1,000,000  have  been  designated  as  Class A  Common  Stock  and  the
remainder are undesignated Common Stock and (ii) 2,000,000 shares of Preferred Stock, of which 250,000 have been designated as Class A Preferred Stock and the remainder
are undesignated preferred stock. Only our 49,000,000 shares of undesignated common stock are being registered hereby.

The  description  of  our  Class A  Common  Stock  in  this  item  is  for  information  purposes  only. All  of  the  Class A  Common  Stock  has  been  issued  to  City  of  Hope.  Class A
Common Stock is identical to common stock other than as to voting rights, the election of directors for a definite period, and conversion rights. On any matter presented to our
stockholders for their action or consideration at any meeting of our stockholders (or by written consent of stockholders in lieu of meeting), each holder of outstanding shares of
Class A Common Stock will be entitled to cast for each share of Class A Common Stock held by such holder as of the record date for determining stockholders entitled to vote
on such matter, the number of votes that is equal to the number of shares of common stock into which the shares of Class A Common Stock are convertible into. Each share of
Class A Common Stock is convertible, at the option of the holder, into one fully paid and nonassessable share of common stock, subject to certain adjustments. For a period of
ten years from its issuance, the holders of the Class A Common Stock have the right to appoint one member of the board of directors of Mustang; to date, the holders of Class A
Common Stock have not yet appointed such director.

The description of our undesignated Preferred Stock in this item is for information purposes only. The undesignated Preferred Stock may be issued from time to time in one or
more  series.  Mustang  Bio’s  Board  of  Directors  is  authorized  to  determine  or  alter  the  dividend  rights,  dividend  rate,  conversion  rights,  voting  rights,  rights  and  terms  of
redemption  (including  sinking  fund  provisions,  if  any),  the  redemption  price  or  prices,  the  liquidation  preferences  and  other  designations,  powers,  preferences  and  relative,
participating,  optional  or  other  special  rights,  if  any,  and  the  qualifications,  limitations  and  restrictions  granted  to  or  imposed  upon  any  wholly  unissued  series  of  Preferred
Stock, and to fix the number of shares of any series of Preferred Stock (but not below the number of shares of any such series then outstanding).

The description of our Class A Preferred Stock in this item is for information purposes only. 250,000 shares of the Class A Preferred Stock have been issued to Fortress. Class
A Preferred Stock is identical to common stock other than as to voting rights, conversion rights and the PIK Dividend right (as described below). On any matter presented to our
stockholders for their action or consideration at any meeting of our stockholders (or by written consent of stockholders in lieu of meeting), each holder of outstanding shares of
Class A Preferred Stock will be entitled to cast for each share of Class A Preferred Stock held by such holder as of the record date for determining stockholders entitled to vote
on such matter, the number of votes that is equal to one and one-tenth (1.1) times a fraction, the numerator of which is the sum of (A) the shares of outstanding Common Stock
and (B) the whole shares of Common Stock in to which the shares of outstanding Class A Common Stock and the Class A Preferred Stock are convertible and the denominator
of which is the number of shares of outstanding Class A Preferred Stock. Thus, the Class A Preferred Stock will at all times constitute a voting majority.  Each share of Class A
Preferred Stock is convertible, at the option of the holder, into one fully paid and nonassessable share of common stock, subject to certain adjustments.

The holders of the outstanding shares of Class A Preferred Stock shall receive on each March 13 (each a “PIK Dividend Payment Date”) after the original issuance date of the
Class A Preferred Stock until the date all outstanding Class A Preferred Stock is converted into Common Stock or redeemed (and the purchase price is paid in full), pro rata per
share dividends paid in additional fully paid and nonassessable shares of Common Stock (such dividend being herein called “PIK Dividends”) such that the aggregate number
of shares of Common Stock issued pursuant to such PIK Dividend is equal to two and one-half percent (2.5%) of the Corporation’s fully-diluted outstanding capitalization on
the date that is one (1) business day prior to any PIK Dividend Payment Date (“PIK Record Date”). In the event the Class A Preferred Stock converts into Common Stock, the
holders shall receive all PIK Dividends accrued through the date of such conversion.

If  Mustang  Bio  at  any  time  effects  a  subdivision  of  the  outstanding  common  stock  (or  other  capital  stock  or  securities  at  the  time  issuable  upon  conversion  of  the  Class A
Common Stock or Class A Preferred Stock) by any stock split, stock dividend, recapitalization or otherwise, the applicable Conversion Ratio in effect immediately before that
subdivision will be proportionately decreased so that the number of shares of common stock (or other capital stock or securities at the time issuable upon conversion of the Class
A Common Stock or Class A Preferred Stock) issuable on conversion of each share of Class A Common Stock or Class A Preferred Stock will be increased in proportion to
such increase in the aggregate number of shares of common stock (or other capital stock or securities at the time issuable upon conversion of the Class A Common Stock or
Class A Preferred Stock) outstanding. If Mustang Bio at any time combines the outstanding shares of common stock, the applicable Conversion Ratio in effect immediately
before the combination will be proportionately increased so that the number of shares of common stock (or other capital stock or securities at the time issuable upon conversion
of the Class A Common Stock or Class A Preferred Stock) issuable on conversion of each share of Class A Common Stock or Class A Preferred Stock will be decreased in
proportion  to  such  decrease  in  the  aggregate  number  of  shares  of  common  stock  (or  other  capital  stock  or  securities  at  the  time  issuable  upon  conversion  of  the  Class A
Common Stock or Class A Preferred Stock) outstanding. Additionally, if any reorganization, recapitalization, reclassification, consolidation or merger involving Mustang Bio
occurs in which the common stock (but not the Class A Common Stock or Class A Preferred Stock) is converted into or exchanged for securities, cash or other property (other
than a transaction involving the subdivision or combination of the common stock), then, following any such reorganization, recapitalization, reclassification, consolidation or
merger, each share of Class A Common Stock and Class A Preferred Stock becomes convertible into the kind and amount of securities, cash or other property which such Class
A  Common  Stockholder  or  Class A  Preferred  Stockholder  would  have  been  entitled  to  receive  had  he  or  she  converted  the  Class A  Shares  or  Class A  Preferred  Shares
immediately before said transaction. In such case, appropriate adjustment (as determined in good faith by the Board of Directors of Mustang Bio) will be made in the application
of the provisions of Mustang Bio’s Certificate of Incorporation, as amended, relating the subdivision or combination of the common stock with respect to the rights and interests
thereafter of the holders of the Class A Common Stock and Class A Preferred Stock, such that the provisions set forth in of Mustang Bio’s Amended and Restated Certificate of
Incorporation  relating  to  the  subdivision  or  combination  of  the  common  stock  (including  the  provisions  with  respect  to  changes  in  and  other  adjustments  of  the  applicable
Conversion Ratio) will thereafter be applicable, as nearly as reasonably may be, in relation to any securities or other property thereafter deliverable upon the conversion of the
Class A Common Stock and Class A Preferred Stock.

Other features of our capital stock include:

distributable ratably among the holders of our common stock, including Class A Common Stock, outstanding at that time after payment of other claims of creditors, if
any.

Fully Paid and Non-Assessable. All of the outstanding shares of our capital stock, including Common Stock, Class A Common Stock and Class A Preferred Stock, are,
and the shares of our Common Stock to be issued pursuant to this offering will be, duly issued, fully paid and non-assessable.

Management’s  Discussion  and  Analysis  of 
Operations

the  Results  of

Forward-Looking Statements

Statements in the following discussion and throughout this Form 10-K that are not historical in nature are “forward-looking statements.” You can identify forward-looking
statements by the use of words such as “expect,” “anticipate,” “estimate,” “may,” “will,” “should,” “intend,” “believe,” and similar expressions. Although we believe the
expectations reflected in these forward-looking statements are reasonable, such statements are inherently subject to risk and we can give no assurances that our expectations
will prove to be correct. Actual results could differ from those described in this Form 10-K because of numerous factors, many of which are beyond our control. These factors
include,  without  limitation,  those  described  under  Item  1A  “Risk  Factors.”  We  undertake  no  obligation  to  update  these  forward-looking  statements  to  reflect  events  or
circumstances after the date of this Form 10-K or to reflect actual outcomes. Please see “Forward Looking Statements” at the beginning of this Form 10-K.

The following discussion of our financial condition and results of operations should be read in conjunction with our financial statements and the related notes thereto and other
financial information appearing elsewhere in this Form 10-K. We undertake no obligation to update any forward looking statements in the discussion of our financial condition
and results of operations to reflect events or circumstances after the date of this Form 10-K or to reflect actual outcomes.

Overview

We are a clinical-stage biopharmaceutical company focused on the development and commercialization of novel cancer immunotherapy products designed to utilize the power
of the patient’s own immune system to eliminate cancer cells. We aim to acquire rights to these technologies by licensing or otherwise acquiring an ownership interest in the
technologies, funding their research and development and eventually either out-licensing or bringing the technologies to market. Currently we are developing our proprietary
Chimeric Antigen Receptor (CAR) engineered T cells (CAR -T) technology, which we licensed from Dr. Stephen Forman’s laboratory at the City of Hope National Medical
Center (COH). CAR-T uses the patient’s own T cells to engage and destroy specific tumors. The process involves selecting specific T-cell subtypes, genetically engineering
them to express chimeric antigen T cell receptors and placing them back in the patient where they recognize and destroy cancer cells.

Our exclusive license and sponsored research agreement with Dr. Stephen Forman’s laboratory at the COH encompasses specific chimeric T cell constructions and enabling
process technologies including linker technology improvements. This agreement covers the discovery, manufacturing and clinical development of novel CAR-T cells along with
specified rights to any and all inventions.

We are currently in Phase 1 trials treating glioblastoma patients. Dr. Forman’s laboratory has developed a proprietary engineered CAR-T cells targeting Interleukin13 Receptor
a2 or MB-101, which is overexpressed on the surface of glioblastoma cells. On December 29, 2016 an article in the New England Journal of Medicine reported that a patient
enrolled in the Phase 1 glioblastoma trial treated with MB-101 achieved a complete response.

We have filed another IND for the treatment of patients with acute myeloid leukemia (AML). Dr. Forman’s laboratory has developed a proprietary CAR-based targeting of
CD123, which is overexpressed on the surface of many cells giving rise to hematologic malignancies, using engineered T cells for treatment of AML.

Additionally,  under  our  sponsored  preclinical  research  agreement  with  COH,  the  COH  is  developing  additional  CAR-T  cell  constructions  targeting  a  number  of  tumor
associated antigens specific for the variety of solid and hematological malignancies. The effectiveness of certain of these additional CAR-T cell constructs already has been
demonstrated  in  preclinical  studies  with  mouse  xenograft  models  of  specific  human  tumors.  Under  the  sponsored  research  agreement,  we  have  the  right  to  license  newly
developed  CAR-T  constructs.  We  intend  to  further  pursue  preclinical  development  to  validate  and  seek  to  establish  the  proprietary  nature  of  the  most  promising  CAR-T
approaches coming out of the sponsored research program and, if successful, we would license and take forward into clinical studies.

To date, we have not received approval for the sale of our product candidates in any market and, therefore, have not generated any product sales from our product candidates. In
addition, we have incurred substantial operating losses since our inception, and expect to continue to incur significant operating losses for the foreseeable future and may never
become profitable. As of December 31, 2016, we have an accumulated deficit of $17.1 million.

In a private placement offering, which commenced September 30, 2016 and expired on January 31, 2017, we have raised gross proceeds of $94.6 million cumulatively in six
separate  closings.  We  paid  National  Securities  Corporation  (“NSC”)  a  cash  fee  totaling  $9.5  million  and  issued  to  them  approximately  601,500  warrants  to  purchase  our
common stock, for their services as placement agent. Fortress owns 56.6% of National Holding Inc., the parent of NSC.

We are a majority controlled subsidiary of Fortress.

Mustang Bio, Inc. was incorporated in Delaware on March 13, 2015. Our executive offices are located at 2 Gansevoort Street, 9th Floor, New York, NY 10014. Our telephone

Critical Accounting Policies and Use of Estimates

Our discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with accounting
principles generally accepted in the United States (“GAAP”). The preparation of these financial statements requires us to make estimates and judgments that affect the reported
amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in our financial statements. On an ongoing basis, we evaluate our
estimates and judgments, including those related to accrued expenses and stock-based compensation. We base our estimates on historical experience, known trends and events
and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of
assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Our significant accounting policies are described in the notes to our financial statements appearing elsewhere in this Form 10-K.

Research and development expenses primarily consist of personnel related expenses, including salaries, benefits, travel, and other related expenses, stock-based compensation,
payments made to third parties for license and milestone costs related to in-licensed products and technology, payments made to third party contract research organizations for
preclinical and clinical studies, investigative sites for clinical trials, consultants, the cost of acquiring and manufacturing clinical trial materials, costs associated with regulatory
filings, laboratory costs and other supplies.

For the year ended December 31, 2016 and for the period from March 13, 2015 (inception) to December 31, 2015, research and development expenses were approximately $2.5
million and $1.7 million, respectively. For the year ended December 31, 2016, $2.0 million relates to the quarterly expense related to our sponsored research agreement with
COH and $250,000 of expense is related to our Management Services Agreement (“MSA”) with Fortress. For the period March 13, 2015 (inception) through December 31,
2015, $1.5 million related to our sponsored research arrangement with the COH for the development of CAR-T and approximately $188,000 of expenses in connection with the
MSA with Fortress.

For the year ended December 31, 2016 and for the period from March 13, 2015 (inception) to December 31, 2015, research and development expenses - licenses acquired were
approximately $6.1 million and $2.3 million, respectively. For the year ended December 31, 2016, approximately $1.7 million relates to 293,588 shares of our common stock
issuable to the City of Hope in connection with our Original License agreement, which provided for COH maintaining a 10% ownership position up to a third party raise equal
to net proceeds of $10.0 million and $4.4 million relates to the stock dividend to Fortress, in connection with their ownership of our Class A preferred stock, of 767,264 shares
of our common stock representing 2.5% of the our fully diluted outstanding shares on the anniversary date of our formation. For the period March 13, 2015 (inception) through
December  31,  2015,  $2.0  million  relates  to  an  upfront  fee  in  the  acquisition  of  the  exclusive  license  with  COH,  to  acquire  CAR-T,  approximately  $147,000  relates  to  the
issuance  of  1.0  million  Class A  shares  of  our  common  stock  valued  at  $147,000  or  $0.147  per  share  (also  to  City  of  Hope),  and  approximately  $190,000  of  expenses  in
connection with the Fortress annual equity fee.

We  expect  our  research  and  development  activities  to  increase  as  we  develop  our  existing  product  candidates  and  potentially  acquire  new  product  candidates,  reflecting
increasing costs associated with the following:

·

·

·

·

·

employee-related expenses, which include salaries and benefits, and rent expense;

license fees and milestone payments related to in-licensed products and technology;

expenses incurred under agreements with contract research organizations, investigative sites and consultants that conduct our clinical trials and our preclinical activities;

the cost of acquiring and manufacturing clinical trial materials; and

costs associated with non-clinical activities, and regulatory approvals.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and related expenses, including stock-based compensation, for executives and other administrative personnel,
recruitment expenses, professional fees and other corporate expenses, including investor relations, legal activities including patent fees, and facilities-related expenses.

For the year ended December 31, 2016 and for the period from March 13, 2015 (inception) to December 31, 2015, general and administrative expenses were approximately $2.8
million  and  $254,000,  respectively.  For  the  year  ended  December  31,  2016,  these  fees  consist  of  $1.3  million  of  legal  fees,  $0.9  million  related  to  the  issuance  of  founder
shares, $290,000 of professional fees and $250,000 of expense in connection with the MSA with Fortress. For the period March 13, 2015 (inception) through December 31,
2015, general and administrative expenses were primarily related to $188,000 of expense in connection with the MSA with Fortress and approximately $66,000 for professional
fees, primarily in connection with the acquisition and maintenance of our license.

We anticipate general and administrative expenses will increase in future periods, reflecting continued and increasing costs associated with:

·

·

·

·

support of our expanded research and development activities;

stock compensation granted to key employees and non-employees;

support of business development activities; and

increased professional fees and other costs associated with the regulatory requirements and increased compliance associated with being a public reporting company.

Other Income (Expenses) 

Other income (expenses) consists primarily of interest expenses, interest income and the change in fair value of derivative warrant liabilities. Interest expense - related party was
approximately $253,000 and $168,000 for the year ended December 31, 2016 and for the period from March 13, 2015 (inception) to December 31, 2015, respectively. Interest
expense, which represents interest on the NSC note, which was fully paid down before year-end, was approximately $895,000 and nil for the year ended December 31, 2016 and
for the period from March 13, 2015 (inception) to December 31, 2015, respectively. Change in fair value of derivative warrants was an expense of approximately $159,000 and
nil for the year ended December 31, 2016 and for the period from March 13, 2015 (inception) to December 31, 2015, respectively.

Liquidity and Capital Resources

We have incurred substantial operating losses since our inception and expect to continue to incur significant operating losses for the foreseeable future and may never become
profitable. As of December 31, 2016, we had an accumulated deficit of $17.1 million.

In  February  2015,  Fortress  closed  a  private  placement  of  a  promissory  note  for  $10  million  through  National  Securities  Corporation  (the  “NSC  Note”).  Fortress  used  the
proceeds from the NSC Note to acquire medical technologies, products and for activities related to the formation of its subsidiaries. The NSC Note matures 36 months after
issuance, provided that during the first 24 months, Fortress can extend the maturity date by six months. No principal amount will be due for the first 24 months after issuance (or
the first 30 months after issuance if the maturity date is extended). Thereafter, the NSC Note will be repaid at the rate of 1/12 of the principal amount per month for a period of
12 months. Interest on the NSC Note is 8%, payable quarterly during the first 24 months after issuance (or the first 30 months after issuance if the NSC Note is extended) and
monthly during the last 12 months. National Securities Corporation (“NSC”), a wholly owned subsidiary of National Holdings, Inc., acted as the sole placement agent for the
NSC Note.

Fortress used some of the proceeds from the NSC Note to acquire our COH license agreement, by transferring this indebtedness to us. Since the NSC Note allows Fortress to
transfer a portion of the proceeds from the NSC Note to us, on July 5, 2016 we executed an identical NSC Note of $3.6 million in favor of NSC, representing a transfer of
Fortress indebtedness. Further, in accordance with the terms of the NSC Note, we issued a warrant to NSC equal to twenty-five percent (25%) of the amount of NSC Note
proceeds we received from Fortress divided by the lowest price at which we next sold common stock. The warrant issued has a term of 10 years and an exercise price equal to
the par value of our common stock.

Our Intercompany Working Capital Promissory Note (“Fortress Note”), was approximately $320,000 at December 31, 2016. We have recorded interest expense of $253,000
and $168,000 related to this note in interest expense - due related party in our Statements of Operations for the year ended December 31, 2016 and for the period from March
13, 2015 (inception) to December 31, 2015, respectively. On July 5, 2016, Fortress transferred $3.6 million of our indebtedness, with a debt discount related to our pro rata
share of Fortress’ debt issuance costs of approximately $129,000, under our Fortress Note to NSC Note.

In  addition,  on  September  30,  2016,  we  received  gross  proceeds  of  $12.4  million,  before  commissions  and  expenses  of  $1.4  million,  in  a  private  placement  of  shares  and
warrants. The financing involved the sale of units, each consisting of 10,000 shares of common stock and a warrant exercisable for 2,500 shares of common stock at an exercise
price  of  $8.50  per  share,  for  a  purchase  price  of  $65,000  per  unit.  We  issued  1,914,833  unregistered  shares  of  Common  Stock  and  478,708  Warrants  in  this  Offering.  The
Placement Agent received 191,483 Placement Agent Warrants.

On October 25, 2016, the Company closed a second round of financing totaling gross proceeds of $7.1 million, before expenses, in a private placement of shares and warrants
for which NSC was the placement agent and received a fee of $700,000 or approximately 10% of the gross proceeds. The financing involved the sale of units, each consisting of
10,000 shares of common stock and a warrant exercisable for 2,500 shares of common stock at an exercise price of $8.50 per share, for a total price of $65,000 per unit. The
warrants have a five-year term and are only exercisable for cash. The Company issued 1,090,580 unregistered shares of Common Stock and 272,645 warrants in connection
with this transaction. In addition, the placement agent received 109,058 warrants or approximately 10% of the shares issued.

On November 30, 2016, the Company closed a third round of financing totaling gross proceeds of $12.4 million, before expenses, in a private placement of shares and warrants
for which NSC was the placement agent and received a fee of $1.2 million or approximately 10% of the gross proceeds. The financing involved the sale of units, each consisting
of 10,000 shares of common stock and a warrant exercisable for 2,500 shares of common stock at an exercise price of $8.50 per share, for a total price of $65,000 per unit. The
warrants have a five-year term and are only exercisable for cash. The Company issued 1,900,215 unregistered shares of Common Stock and 475,053 warrants in connection
with this transaction. In addition, the placement agent received 190,021 warrants or approximately 10% of the shares issued.

On December 12, 2016, the Company closed a fourth round of financing totaling gross proceeds of $3.1 million, before expenses, in a private placement of shares and warrants
for which NSC was the placement agent and received a fee of $310,000 or approximately 10% of the gross proceeds. The financing involved the sale of units, each consisting of
10,000 shares of common stock and a warrant exercisable for 2,500 shares of common stock at an exercise price of $8.50 per share, for a total price of $65,000 per unit. The
warrants have a five-year term and are only exercisable for cash. The Company issued 477,000 unregistered shares of Common Stock and 119,250 warrants in connection with
this transaction. In addition, the placement agent received 47,700 warrants or approximately 10% of the shares issued.

On December 29, 2016, the Company closed a fifth round of financing totaling gross proceeds of $4.1 million, before expenses, in a private placement of shares and warrants
for which NSC was the placement agent and received a fee of $410,000 or approximately 10% of the gross proceeds. The financing involved the sale of units, each consisting of
10,000 shares of common stock and a warrant exercisable for 2,500 shares of common stock at an exercise price of $8.50 per share, for a total price of $65,000 per unit. The
warrants have a five-year term and are only exercisable for cash. The Company issued 632,246 unregistered shares of Common Stock and 158,062 warrants in connection with
this transaction. In addition, the placement agent received 63,224 warrants or approximately 10% of the shares issued.

We expect to use the net proceeds from the above transaction primarily for general corporate purposes, which may include financing our growth, developing new or existing
product candidates, and funding capital expenditures, acquisitions and investments. We currently anticipate that our cash balances at December 31, 2016, are sufficient to fund
its anticipated operating cash requirements for approximately the next 12 months.

Net  cash  used  in  operating  activities  was  $4.1  million  for  the  year  ended  December  31,  2016,  compared  to  $1.6  million  for  the  period  from  March  13,  2015  (inception)  to
December 31, 2015. Net cash used in operating activities during the year ended December 31, 2016 was primarily due to approximately $12.7 million in net loss, partially offset
by  approximately  $4.4  million  of  common  shares  issuable  for  Founder  shares,  $1.7  million  related  to  the  issuance  of  Class  A  common  shares  for  license  expenses,
approximately $862,000 related to the issuance of common shares – Founders Agreement, approximately $763,000 in debt discount amortization, and approximately $663,000
of increase in operating liabilities. Net cash used in operating activities during the period from March 13, 2015 (inception) to December 31, 2015 was primarily due to a $4.5
million in net loss, partially offset by $2.0 million related to the acquired licenses and approximately $558,000 of increase in operating liabilities.

 Item 7A.

Quantitative and Qualitative Disclosures About Market Risks

Market risk represents the risk of loss that may result from the change in value of financial instruments due to fluctuations in their market price. Market risk is inherent in all
financial instruments. Market risk may be exacerbated in times of trading illiquidity when market participants refrain from transacting in normal quantities and/or at normal bid-
offer spreads. Our exposure to market risk is directly related to derivatives, debt and equity linked instruments related to our financing activities.

Our assets and liabilities are denominated in U.S. dollars. Consequently, we have not considered it necessary to use foreign currency contracts or other derivative instruments to
manage changes in currency rates. We do not now, nor do we plan to, use derivative financial instruments for speculative or trading purposes. However, these circumstances
might change.

The  primary  quantifiable  market  risk  associated  with  our  financial  instruments  is  sensitivity  to  changes  in  interest  rates.  Interest  rate  risk  represents  the  potential  loss  from
adverse changes in market interest rates. We use an interest rate sensitivity simulation to assess our interest rate risk exposure. For purposes of presenting the possible earnings
effect of a hypothetical, adverse change in interest rates over the 12-month period from our reporting date, we assume that all interest rate sensitive financial instruments will be
impacted by a hypothetical, immediate 100 basis point increase in interest rates as of the beginning of the period. The sensitivity is based upon the hypothetical assumption that
all relevant types of interest rates that affect our results would increase instantaneously, simultaneously and to the same degree. We do not believe that our cash and equivalents
have significant risk of default or illiquidity.

The sensitivity analyses of the interest rate sensitive financial instruments are hypothetical and should be used with caution. Changes in fair value based on a 1% or 2% variation
in an estimate generally cannot be extrapolated because the relationship of the change in the estimate to the change in fair value may not be linear. Also, the effect of a variation
in a particular estimate on the fair value of financial instruments is calculated independent of changes in any other estimate; in practice, changes in one factor may result in
changes in another factor, which might magnify or counteract the sensitivities. In addition, the sensitivity analyses do not consider any action that we may take to mitigate the
impact of any adverse changes in the key estimates.

Based on our analysis, as of December 31, 2016, the effect of a 100+/- basis point change in interest rates on the value of our financial instruments and the resultant effect on
our net loss are considered immaterial.

Disclosure Controls and Procedures

Controls and Procedures

Disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) are designed only to provide reasonable assurance that they will meet their
objectives.  Under  the  supervision  and  with  the  participation  of  our  management,  including  our  principal  executive  officer  and  principal  financial  officer,  we  conducted  an
evaluation  of  the  effectiveness,  as  of  December  31,  2015,  of  the  design  and  operation  of  our  disclosure  controls  and  procedures,  as  such  term  is  defined  in  Exchange Act
Rules  13a-15(e)  and  15d-15(e).  Based  on  this  evaluation,  our  principal  executive  officer  and  principal  financial  officer  have  concluded  that,  as  of  such  date,  our  disclosure
controls and procedures are effective to ensure that information required to be disclosed by us in our Exchange Act reports 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  principal
executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Internal Control over Financial Reporting

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 Exchange Act Rules 13a-15(f) and
15d-15(f). Internal control over financial reporting refers to the process designed by, or under the supervision of, our principal executive officer and principal financial officer,
and effected by our Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of
financial statements for external purposes in accordance with generally accepted accounting principles, and includes those policies and procedures that:

(1) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;

(2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that our receipts

and expenditures are being made only in accordance with authorization of our management and directors; and

(3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisitions, use or disposition of our assets that could have a material effect

on the financial statements.

48

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Internal  control  over  financial  reporting  has  inherent  limitations.  Internal  control  over  financial  reporting  is  a  process  that  involves  human  diligence  and  compliance  and  is
subject  to  lapses  in  judgment  and  breakdowns  resulting  from  human  failures.  Internal  control  over  financial  reporting  also  can  be  circumvented  by  collusion  or  improper
management  override.  Because  of  such  limitations,  there  is  a  risk  that  material  misstatements  may  not  be  prevented  or  detected  on  a  timely  basis  by  internal  control  over
financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to
reduce, though not eliminate, this risk.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2016. In making the assessment, management used the criteria
set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework (2013).

Based on our assessment, our management has concluded that, as of December 31, 2016, our internal controls over financial reporting were effective based upon those criteria.

Changes in Internal Controls over Financial Reporting.

There were no changes in our internal control over financial reporting during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially
affect, our internal control over financial reporting.

 Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders
Mustang Bio, Inc.
New York, New York

We have audited the accompanying balance sheet of Mustang Bio, Inc. as of December 31, 2016 and the related statements of operations, stockholders’ equity (deficit), and
cash flows for the year ended December 31, 2016. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion
on these financial statements based on our audit.

We  conducted  our  audit  in  accordance  with  the  standards  of  the  Public  Company Accounting  Oversight  Board  (United  States)  and  in  accordance  with  auditing  standards
generally  accepted  in  the  United  States  of America.  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable  assurance  about  whether  the  financial
statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our
audit  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, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Mustang Bio, Inc. at December 31, 2016, and the results
of its operations and its cash flows for the year ended December 31, 2016, in conformity with accounting principles generally accepted in the United States of America.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Stockholders of
Mustang Bio, Inc.
New York, NY

We  have  audited  the  accompanying  balance  sheet  of Mustang Bio, Inc.  (the  “Company”)  as  of  December  31,  2015,  and  the  related  statements  of  operations,  stockholders’
deficit, and cash flows for the period from March 13, 2015 (inception) through December 31, 2015. The Company’s management is responsible for these financial statements.
Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to
perform,  an  audit  of  its  internal  control  over  financial  reporting.  Our  audit  included  consideration  of  internal  control  over  financial  reporting  as  a  basis  for  designing  audit
procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial
reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements.
An  audit  also  includes  assessing  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as  evaluating  the  overall  financial  statement
presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Mustang Bio, Inc. as of December 31, 2015, and the
results of its operations and cash flows for the period from March 13, 2015 (inception) through December 31, 2015, in conformity with accounting principles generally accepted
in the United States of America.

The accompanying financial statements have been prepared assuming the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the
Company  has  incurred  recurring  losses  from  operations,  and  is  dependent  on  additional  financing  to  fund  operations.  These  conditions  raise  substantial  doubt  about  the
Company’s ability to continue as a going concern. Management’s plans in regard to these matters are described in Note 1 to the financial statements. The 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.

Note 1 — Organization, Plan of Business Operations

 MUSTANG BIO, INC.
Notes to Financial Statements

Mustang Bio, Inc. (the “Company” or “Mustang”) was incorporated in Delaware on March 13, 2015, as a majority-owned subsidiary of Fortress Biotech, Inc. (“Fortress” or
“Parent”)  and  commenced  its  principal  operations  on  March  13,  2015.  Mustang  was  formed  as  a  clinical-stage  biopharmaceutical  company  focused  on  the  acquisition,
development and commercialization of novel cancer immunotherapy products designed to utilize the power of the patient’s own immune system to eliminate cancer cells. The
Company  may  acquire  rights  to  these  technologies  by  licensing  the  rights  or  otherwise  acquiring  an  ownership  interest  in  the  technologies,  funding  their  research  and
development and eventually either out-licensing or bringing the technologies to market.

Chimeric Antigen Receptor (CAR) engineered T-cells (CAR-T) technology

In March 2015, Mustang entered into an exclusive license and sponsored research agreement with the City of Hope National Medical Center (“COH”), collectively referred to
as “COH Agreements”, to acquire CAR-T. CAR-T uses the patient’s own T-cells to engage and destroy specific tumors. The process involves selecting specific T-cell subtypes,
genetically engineering them to express chimeric antigen T cell receptors and placing them back in the patient where they recognize and destroy cancer cells. The exclusive
license agreement covers the discovery, manufacture and clinical development of novel CAR-T along with specified rights to any and all inventions.

On February 17, 2017, the Company and COH amended and restated the Original Agreement in connection with the covered patents by entering into three separate amended
and  restated  exclusive  license  agreements,  one  relating  to  CD123,  one  relating  to  IL-13  and  one  relating  to  the  spacer  technology,  that  amended  the  Original Agreement  in
certain other respects, and collectively replace the Original Agreement in its entirety. The total potential consideration payable to COH by the Company, in equity or cash, did
not, in the aggregate, change materially from the Original Agreement.

Note 2 — Significant Accounting Policies 

Basis of Presentation

The Company’s financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company
has no subsidiaries.

The financial statements may not be indicative of future performance and may not reflect what the Company’s results of operations, financial position, and cash flows would
have  been  had  Mustang  operated  as  an  independent  entity.  Certain  estimates  have  been  made  to  provide  financial  statements  for  stand-alone  reporting  purposes. All  inter-
company transactions between Fortress and Mustang are classified as due to related party in the financial statements. The Company believes that the assumptions underlying the
financial statements are reasonable.

Use of Estimates

The  preparation  of  financial  statements  in  conformity  with  GAAP  requires  management  to  make  estimates  and  assumptions  that  affect  the  reported  amounts  of  assets  and
liabilities  and  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  the  financial  statements  and  the  reported  amounts  of  expenses  during  the  reporting  period. Actual
results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. There were no cash equivalents at
December 31, 2016 and 2015.

Research and Development Costs

Research  and  development  costs  are  expensed  as  incurred. Advance  payments  for  goods  and  services  that  will  be  used  in  future  research  and  development  activities  are
expensed when the activity has been performed or when the goods have been received rather than when the payment is made. Upfront and milestone payments due to third
parties that perform research and development services on the Company’s behalf will be expensed as services are rendered or when the milestone is achieved.

Research  and  development  costs  primarily  consist  of  personnel  related  expenses,  including  salaries,  benefits,  travel,  and  other  related  expenses,  stock-based  compensation,
payments made to third parties for license and milestone costs related to in-licensed products and technology, payments made to third party contract research organizations for
preclinical and clinical studies, investigative sites for clinical trials, consultants, the cost of acquiring and manufacturing clinical trial materials, costs associated with regulatory
filings, laboratory costs and other supplies.

MUSTANG BIO, INC.
Notes to Financial Statements

Costs incurred in obtaining technology licenses are charged to research and development expense if the technology licensed has not reached commercial feasibility and has no
alternative future use. The licenses purchased by the Company require substantial completion of research and development, regulatory and marketing approval efforts in order
to  reach  commercial  feasibility  and  has  no  alternative  future  use. Accordingly,  the  total  purchase  price  for  the  licenses  acquired  is  reflected  as  research  and  development  –
licenses acquired on the Company’s Statements of Operations.

Annual Equity Fee

Prior to the July 2016 amendment to the Founder’s Agreement, Fortress was entitled to an annual fee on each anniversary date equal to 2.5% of the fully diluted outstanding
equity  of  the  Company,  payable  in  Mustang  Class  B  Common  Stock  (“Annual  Equity  Fee”).  The  annual  equity  fee  was  part  of  consideration  payable  for  formation  of  the
Company and identification of certain assets.

The Company recorded the Annual Equity Fee in connection with the Founders Agreement with Mustang as contingent consideration. Contingent consideration is recorded
when probable and reasonably estimable. The Company’s future share prices cannot be estimated due to the nature of its assets and the Company’s stage of development. Due
to these uncertainties, the Company concluded that it could not reasonably estimate the contingent consideration until shares were actually issued on March 13, 2016. Because
the  issuance  of  shares  on  March  13,  2016  occurred  prior  to  the  issuance  of  the  December  31,  2015  financial  statements,  the  Company  recorded  approximately  $190,000  in
research and development - licenses acquired during the period from March 13, 2015 (inception) through December 31, 2015. Pursuant to the terms of the Mustang Founders
Agreement, as amended in July 2016, this equity fee is no longer payable.

Annual Stock Dividend

In July 2016, in connection with the Amended and Restated Articles of Incorporation, the Company issued 250,000 Class A preferred shares to Fortress. The Class A preferred
shares entitle the holder to a stock dividend equal to 2.5% of the fully diluted outstanding equity of the Company.

The Company recorded the Annual Stock Dividend due Fortress as contingent consideration. Contingent consideration is recorded when probable and reasonably estimable.
The  Company’s  future  share  prices  cannot  be  estimated  due  to  the  nature  of  its  assets  and  the  Company’s  stage  of  development.  Due  to  these  uncertainties,  the  Company
concluded that it could not reasonably estimate the contingent consideration until shares were actually issued on March 13, 2017. Because the issuance of shares on March 13,
2017 occurred prior to the issuance of the December 31, 2016 financial statements, the Company recorded approximately $4.4 million in research and development - licenses
acquired for the year ended December 31, 2016.

Fair Value Measurement

The Company follows accounting guidance on fair value measurements for financial assets and liabilities measured at fair value on a recurring basis. Under the accounting
guidance, fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between
market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would
use in pricing an asset or a liability.

The accounting guidance requires fair value measurements be classified and disclosed in one of the following three categories:

Level 1:

Quoted prices in active markets for identical assets or liabilities.

Level 2:

Observable inputs other than Level 1 prices, for similar assets or liabilities that are directly or indirectly observable in the marketplace.

Level 3:

Unobservable inputs which are supported by little or no market activity and that are financial instruments whose values are determined using pricing models,
discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or
estimation.

The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Assets and
liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of
the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability.

Valuation of Warrant Related to NSC Note

MUSTANG BIO, INC.
Notes to Financial Statements

In accordance with ASC 815, the Company classified the fair value of the warrant (“Contingently Issuable Warrants”) that may have been granted in connection with the NSC
Note transferred to the Company in various tranches from July 5, 2016 to October 25, 2016 as a derivative liability as there was a potential that the Company would not have a
sufficient number of authorized common shares available to settle this instrument. The Company valued these Contingently Issuable Warrants using an option pricing model
(which approximates intrinsic value) with estimates for an expected dividend yield, a risk-free interest rate, and expected volatility together with management’s estimate of the
probability of issuance of the Contingently Issuable Warrants. At each reporting period, as long as the Contingently Issuable Warrants were potentially issuable and there was a
potential for an insufficient number of authorized shares available to settle the Contingently Issuable Warrants, the Contingently Issuable Warrants should be revalued and any
difference from the previous valuation date would be recognized as a change in fair value in the Company’s Statement of Operations.

Reclassified Equity Contracts

The Company accounts for potential shares that can be converted to common stock and if converted, will be in excess of authorized shares, as a liability that is recorded on the
balance sheet (at fair value) only until the authorized number of shares is increased (at which time the whole liability will be re-measured, with changes in value included in
other income/(expense), and then reclassified to additional paid-in capital). The value of the liability was computed by valuing the securities that management believed were
most likely to be converted. This liability is revalued at each reporting date with any change in value included in other income / (expense) until such time as enough shares are
authorized to cover all potentially convertible instruments.

Income Taxes

For purposes of these financial statements, the Company’s income tax expense and deferred tax balances have been recorded as if it filed tax returns on a stand-alone basis
separate from Fortress.

Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities measured at the enacted tax rates
in  effect  for  the  year  in  which  these  items  are  expected  to  reverse.  Deferred  tax  assets  are  reduced  by  valuation  allowances  if,  based  on  the  consideration  of  all  available
evidence, it is more likely than not that some portion or all of the deferred tax asset will not be realized.

Net Loss per Share

Net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Since dividends are declared, paid and set
aside among the holders of shares of common stock and Class A Common Stock pro-rata on an as-if-converted basis, the two-class method of computing net loss per share is
not required. Diluted net loss per share does not reflect the effect of shares of common stock to be issued upon the exercise of warrants or outstanding Class A preferred shares,
as  their  inclusion  would  be  anti-dilutive.  There  are  2,243,664  warrants  outstanding  and  250,000  Class A  preferred  shares  outstanding  as  of  December  31,  2016  and  none
outstanding as of December 31, 2015, respectively which are excluded from the computations of net loss per share.

Stock-Based Compensation Expenses

The Company expenses stock-based compensation to employees over the requisite service period based on the estimated grant-date fair value of the awards and forfeiture rates.
For stock-based compensation awards to non-employees, the Company re-measures the fair value of the non-employee awards at each reporting period prior to vesting and
finally at the vesting date of the award. Changes in the estimated fair value of these non-employee awards are recognized as stock-based compensation expense in the period of
change.

Recently Issued Accounting Standards

In  January  2017,  the  Financial Accounting  Standards  Board  ("FASB")  issued Accounting  Standards  Update  ("ASU")  No.  2017-04, Intangibles  -  Goodwill  and  Other (Topic
350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"), which eliminates the second step of the previous FASB guidance for testing goodwill for impairment and
is intended to reduce cost and complexity of goodwill impairment testing. The amendments in this ASU modify the concept of impairment from the condition that exists when
the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. After determining
if the carrying amount of a reporting unit exceeds its fair value, the entity should take an impairment charge of the same amount to the goodwill for that reporting unit, not to
exceed  the  total  goodwill  amount  for  that  reporting  unit.  This  eliminates  the  second  step  of  calculating  the  implied  fair  value  of  goodwill  by  assigning  the  fair  value  of  a
reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. ASU 2017-04 is effective for annual periods beginning after
December 15, 2019, including interim periods within those annual periods. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing
dates after January 1, 2017. The Company is currently evaluating the impact of adopting the new guidance on its financial statements.

MUSTANG BIO, INC.
Notes to Financial Statements

In  January  2017,  FASB  issued ASU  2017-01,  “Business  Combinations  (Topic  805)  Clarifying  the  Definition  of  a  Business”.  The  amendments  in  this  Update  is  to  clarify
the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of
assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The guidance is effective for
annual periods beginning after December 15, 2017, including interim periods within those periods. The Company is currently evaluating the impact of adopting this guidance.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash
flow issues with the objective of reducing the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash
flows. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted, including
adoption in an interim period. The Company is currently in the process of evaluating the impact of this new pronouncement on its statements of cash flows.

In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customer (“ASU 2016-10”). The new guidance is an update to ASC 606 and provides clarity on:
identifying performance obligations and licensing implementation. For public companies, ASU 2016-10 is effective for annual periods, including interim periods within those
annual periods, beginning after December 15, 2016. The Company is currently evaluating the impact that ASU 2016-10 will have on its financial statements.

In March 2016, the FASB issued ASU 2016-09 Compensation-Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting  (“ASU  2016-
09”) . Under ASU 2016-09, companies will no longer record excess tax benefits and certain tax deficiencies in additional paid-in capital (“APIC”). Instead, they will record all
excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement and the APIC pools will be eliminated. In addition, ASU 2016-09 eliminates
the requirement that excess tax benefits be realized before companies can recognize them. ASU 2016-09 also requires companies to present excess tax benefits as an operating
activity on the statement of cash flows rather than as a financing activity. Furthermore, ASU 2016-09 will increase the amount an employer can withhold to cover income taxes
on awards and still qualify for the exception to liability classification for shares used to satisfy the employer’s statutory income tax withholding obligation. An employer with a
statutory income tax withholding obligation will now be allowed to withhold shares with a fair value up to the amount of taxes owed using the maximum statutory tax rate in the
employee’s applicable jurisdiction(s). ASU 2016-09 requires a company to classify the cash paid to a tax authority when shares are withheld to satisfy its statutory income tax
withholding obligation as a financing activity on the statement of cash flows. Under current GAAP, it was not specified how these cash flows should be classified. In addition,
companies will now have to elect whether to account for forfeitures on share-based payments by (1) recognizing forfeitures of awards as they occur or (2) estimating the number
of  awards  expected  to  be  forfeited  and  adjusting  the  estimate  when  it  is  likely  to  change,  as  is  currently  required.  The Amendments  of  this ASU  are  effective  for  reporting
periods beginning after December 15, 2016, with early adoption permitted but all of the guidance must be adopted in the same period. The Company is currently assessing the
impact the adoption of ASU 2016-09 will have on its financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) which supersedes FASB Accounting Standards Codification (“ASC”) Topic 840, Leases (Topic 840) and
provides  principles  for  the  recognition,  measurement,  presentation  and  disclosure  of  leases  for  both  lessees  and  lessors.  The  new  standard  requires  lessees  to  apply  a  dual
approach,  classifying  leases  as  either  finance  or  operating  leases  based  on  the  principle  of  whether  or  not  the  lease  is  effectively  a  financed  purchase  by  the  lessee.  This
classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A
lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than twelve months regardless of classification. Leases with a term of
twelve months or less will be accounted for similar to existing guidance for operating leases. The standard is effective for annual and interim periods beginning after December
15, 2018, with early adoption permitted upon issuance. The Company is currently evaluating the method of adoption and the impact of adopting ASU 2016-02 on its financial
statements. When adopted, the Company does not expect this guidance to have a material impact on its financial statements.

In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities.  ASU 2016-01 requires equity investments to be
measured at fair value with changes in fair value recognized in net income; simplifies the impairment assessment of equity investments without readily determinable fair values
by requiring a qualitative assessment to identify impairment; eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used
to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; requires public business entities to use the
exit price notion when measuring the fair value of financial instruments for disclosure purposes; requires an entity to present separately in other comprehensive income the
portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair

Notes to Financial Statements

In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”). ASU 2015-17 requires that deferred tax liabilities and
assets  be  classified  as  noncurrent  in  a  classified  statement  of  financial  position. ASU  2015-17  is  effective  for  financial  statements  issued  for  fiscal  years  beginning  after
December 15, 2016, and interim periods within those fiscal years. The Company is currently evaluating the impact that ASU 2015-17 will have on its balance sheet or financial
statement disclosures. When adopted, the Company does not expect this guidance to have a material impact on its financial statements.

Recently Adopted Accounting Pronouncements

In  November  2015,  the  FASB  issued ASU  2015-17,  Balance  Sheet  Classification  of  Deferred  Taxes,  which  requires  that  deferred  tax  liabilities  and  assets  be  classified  as
noncurrent  in  a  classified  statement  of  financial  position  to  simplify  the  presentation  of  deferred  income  taxes.  The  standard  is  effective  prospectively  for  fiscal  years,  and
interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. As of December 31, 2016, the Company elected to early adopt the
pronouncement on a prospective basis. Adoption of this amendment did not have an effect on the Company's financial position or results of operations, and prior periods were
not retrospectively adjusted.

In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”), which requires debt issuance costs to be presented in the
balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. ASU 2015-03 is effective for the
interim and annual periods ending after December 15, 2015, with early adoption permitted. The Company adopted ASU 2015-03 on March 31, 2015. The adoption did not have
an impact on the financial statements or related disclosures.

In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements-Going Concern (“ASU 2014-15”), which defines management’s responsibility to assess
an entity’s ability to continue as a going concern, and to provide related footnote disclosures if there is substantial doubt about its ability to continue as a going concern. ASU
2014-15 is effective for annual reporting periods ending after December 15, 2016, with early adoption permitted. The Company adopted ASU 2014-15 in the fourth quarter of
2016 and its adoption did not have an impact on the financial statements or related disclosures.

Note 3 – COH Agreements

The CAR-T Agreements

City of Hope

On March 17, 2015, the Company entered into an exclusive license agreement with COH to acquire intellectual property rights pertaining to CAR-T (the “Original Agreement”).
Pursuant  to  the  agreement,  the  Company  paid  COH  an  upfront  fee  of  $2.0  million,  in April  2015  (included  in research  and  development-licenses  acquired  expenses  on  the
Statements of Operations), and granted COH 1,000,000 shares of Mustang’s Class A Common Stock, representing 10% ownership of Mustang, as of such date. The Company
valued  the  stock  grant  to  COH  utilizing  a  discounted  cash  flow  model  to  determine  the  weighted  market  value  of  invested  capital,  discounted  by  a  lack  of  marketability  of
44.8% and a weighted average cost of capital of 30%, resulting in a $0.147 value per share or approximately $147,000 and is included in research and development-licenses
acquired expenses on the Statements of Operations.

In February 2017, COH was granted 293,588 additional shares of the Company’s Common Stock, the shares were valued utilizing a weighted market model at approximately
$5.73 per share or approximately $1.7 million as of October 2016, the effective date of the grant. The price per share was derived by utilizing the Option Pricing Method for
allocating the enterprise value to the differing security holders, using a volatility of 77.0%, no discount for lack of marketability and a risk free rate of return of 1.93%. This
additional grant was made pursuant to the terms of the agreement, which maintained COH ownership at 10% until the Company raised net proceeds of $10.0 million from third
party  investors. At  December  31,  2016,  since  the  Company  did  not  have  sufficient  authorized  Class A  Common  Shares  available  to  issue  this  grant  it  was  recorded  on  the
balance sheet as a current liability in common share issuable. In February 2017, COH executed a waiver and acknowledgement agreement permitting issuance of the COH Anti-
Dilution Shares in the form of Mustang Common Stock rather than Class A Common Stock as originally required, and such shares were issued.

In addition, the Company entered into a sponsored research agreement with COH in which the Company will fund continued research in the amount of $2.0 million per year,
payable in four equal installments, over the next five years. For the year ended December 31, 2016 and for the period from March 13, 2015 (inception) to December 31, 2015,
the Company recorded $2.0 million and $1.5 million, respectively, in research and development expenses on the Statements of Operation.

In December 2016, the Company entered into two consulting agreements, one with two City of Hope scientists, whereby effective January 1, 2017, in exchange for services
provided to the Company each consultant shall be paid $60,000 per year, paid quarterly, through January 31, 2019. Further each consultant has agreed to serve on our
Scientific Advisory Board on an as needed basis, and will receive additional compensation for those services. In addition, for services provided during the fourth quarter of
2016, pursuant to the terms of the agreement each consultant earned $60,000, which was paid in the first quarter of 2017. As of December 31, 2016, the City of Hope owns
1,000,000 Class A common shares representing approximately 6.1% of ownership and has the right to appoint a director to our Board of Directors. At December 30, 2015 the
City of Hope owned approximately 10% of the Company.

MUSTANG BIO, INC.
Notes to Financial Statements

From March 13, 2015 (inception) through December 31, 2015, in accordance with the Original Founders Agreement, the Company issued 250,000 shares of Common Stock to
Fortress at $0.147 per share or $36,750 in connection with the equity fee payable to Fortress under the original Founders Agreement. This amount was recorded in research and
development  licenses  acquired  expenses  on  the  Statement  of  Operations  for  the  period  from  March  13,  2015  (inception)  through  December  31,  2015.  For  the  period  ended
December 31, 2016 the Company recorded in research and development licenses acquired expenses on the Statement of Operations $4.4 million or 767,264 shares of common
stock at $5.73 in connection with the stock dividend payable in to Fortress pursuant to the terms of the Class A preferred shares.

Note 4 – Related Party Agreements

Founders Agreement and Management Services Agreement with Fortress

Effective  March  13,  2015,  the  Company  entered  a  Founders Agreement  with  Fortress,  which  was  amended  and  restated  on  May  17,  2016  and  again  on  July  26,  2016  (the
“Mustang  Founders Agreement”).  The  Mustang  Founders Agreement  provides  that,  in  exchange  for  the  time  and  capital  expended  in  the  formation  of  Mustang  and  the
identification of specific assets the acquisition of which result in the formation of a viable emerging growth life science company, Fortress loaned $2.0 million, representing the
up-front fee required to acquire the Company’s license agreement with COH. The Mustang Founders Agreement has a term of 15 years, which upon expiration automatically
renews  for  successive  one-year  periods  unless  terminated  by  Fortress  and  the  Company  or  a  Change  in  Control  (as  defined  in  the  Mustang  Founders Agreement)  occurs.
Concurrently with the second amendment on July 26, 2016, to the Mustang Founders Agreement, Fortress entered into an Exchange Agreement whereby Fortress exchanged its
7.25 million Class B Common shares for 7.0 million common shares and 250,000 Class A Preferred shares. Class A Preferred Stock is identical to common stock other than as
to voting rights, conversion rights and the PIK Dividend right (as described below). Each share of Class A Preferred Stock will be entitled to vote the number of votes that is
equal  to  one  and  one-tenth  (1.1)  times  a  fraction,  the  numerator  of  which  is  the  sum  of  (A)  the  shares  of  outstanding  Mustang  common  stock  and  (B)  the  whole  shares  of
Mustang common stock into which the shares of outstanding Class A Common Stock and Class A Preferred Stock are convertible and the denominator of which is the number
of shares of outstanding Class A Preferred Stock. Thus, the Class A Preferred Stock will at all times constitute a voting majority. Each share of Class A Preferred Stock is
convertible, at Fortress’ option, into one fully paid and nonassessable share of Mustang common stock, subject to certain adjustments. As holders of Class A Preferred Stock,
Fortress  will  receive  on  each  March  13  (each  a  “PIK  Dividend  Payment  Date”)  until  the  date  all  outstanding  Class A  Preferred  Stock  is  converted  into  common  stock  or
redeemed (and the purchase price is paid in full), pro rata per share dividends paid in additional fully paid and nonassessable shares of common stock (“PIK Dividends”) such
that the aggregate number of shares of common stock issued pursuant to such PIK Dividend is equal to two and one-half percent (2.5%) of Mustang’s fully-diluted outstanding
capitalization on the date that is one (1) business day prior to any PIK Dividend Payment Date.

As additional consideration under the Mustang Founders Agreement, Mustang will also: (i) pay an equity fee in shares of common stock, payable within five (5) business days
of the closing of any equity or debt financing for Mustang or any of its respective subsidiaries that occurs after the effective date of the Mustang Founders Agreement and
ending on the date when Fortress no longer has majority voting control in the Company’s voting equity, equal to two and one-half (2.5%) of the gross amount of any such equity
or debt financing; and (ii) pay a cash fee equal to four and one-half percent (4.5%) of the Company’s annual net sales, payable on an annual basis, within ninety (90) days of the
end of each calendar year. In the event of a Change in Control, the Company will pay a one-time change in control fee equal to five (5x) times the product of (A) net sales for the
twelve (12) months immediately preceding the change in control and (B) four and one-half percent (4.5%).

On March 13, 2016, pursuant to the then in effect Mustang Founders Agreement, on the anniversary date of the Founders’ Agreement, the Company issued 250,000 shares of
its Class B Common Stock to Fortress representing 2.5% of the fully diluted outstanding shares of the Company. Pursuant to the terms of the Mustang Founders Agreement, as
amended in July 2016, this equity fee is no longer payable.

Effective as of March 13, 2015, the Company entered into a Management Services Agreement (the “MSA”) with Fortress. Pursuant to the terms of the MSA, for a period of five
years,  Fortress  will  render  advisory  and  consulting  services  to  the  Company.  Services  provided  under  the  MSA  may  include,  without  limitation,  (i)  advice  and  assistance
concerning any and all aspects of the Company’s operations, clinical trials, financial planning and strategic transactions and financings and (ii) conducting relations on behalf of
the  Company  with  accountants,  attorneys,  financial  advisors  and  other  professionals  (collectively,  the  “Services”).  The  Company  is  obligated  to  utilize  clinical  research
services, medical education, communication and marketing services and investor relations/public relation services of companies or individuals designated by Fortress, provided
those services are offered at market prices. However, the Company is not obligated to take or act upon any advice rendered from Fortress and Fortress shall not be liable for any
of its actions or inactions based upon their advice. Fortress and its affiliates, including all members of the Company’s Board of Directors, have been contractually exempt from
fiduciary duties to the Company relating to corporate opportunities. In consideration for the Services, the Company will pay Fortress an annual consulting fee of $0.5 million
(the “Annual Consulting Fee”), payable in advance in equal quarterly installments on the first business day of each calendar quarter in each year, provided, however, that such
Annual Consulting Fee shall be increased to $1.0 million for each calendar year in which the Company has net assets in excess of $100 million at the beginning of the calendar
year. For the year ended December 31, 2016 and for the period from March 13, 2015 (inception) to December 31, 2015, the Company recorded approximately $500,000 and
$375,000, respectively, as expense related to this agreement.

Consulting Agreement with Chord Advisors, LLC (“Chord”)

MUSTANG BIO, INC.
Notes to Financial Statements

On April 8, 2016, the Company entered into a full service consulting agreement with Chord to provide advisory accounting services to the Company. Under the terms of the
agreement, the Company paid Chord up to $5,000 per month to perform back office accounting functions, accounting analysis and financial reporting prior to the Company’s
filing  of  its  Registration  Statement  on  Form  10  on  July  27,  2016,  and  $7,500  per  month  following  that  date.  Either  party  upon  30-days  written  notice  can  terminate  the
agreement.  In  addition  to  these  services,  Mr.  Horin,  a  Managing  Partner  of  Chord,  serves  as  the  Company’s  Interim  Chief  Financial  Officer.  Chord  also  provides  advisory
accounting services to Fortress under a separate agreement. For the year ended December 31, 2016 and for the period from March 13, 2015 (inception) to December 31, 2015,
the Company recognized approximately $48,000 and nil, respectively, in general and administrative expenses on the Statements of Operations, related to this agreement.

Fortress Note

The Company has a working capital promissory note with Fortress (see Note 5).

NSC Note and Financings

In September 2016, Fortress acquired through a tender offer 56.6% of National Holdings, Inc. (“National” or “NHLD”). The Company holds a $3.6 million note in favor of
NSC Biotech Venture Fund I, LLC for which National Securities, Inc. (“NSC”) a subsidiary of National received a 10% placement fee upon issuance of the Note to Fortress
(see Note 5).

In September 2016, the Company entered into a Placement Agent Agreement with National in connection with financing in which the Company agreed to pay NSC a cash fee of
10.0% of the gross proceeds and warrants equal to 25% of the total offering (see Note 8). For the year ended December 31, 2016 the Company paid NSC $3.6 million and
issued warrants for 601,486 shares.

Note 5 - Notes Payable

Fortress Note

In 2015, the Company and Fortress entered into an Intercompany Working Capital Promissory Note (“Fortress Note”), in which Fortress agreed to provide a working capital
line of credit to the Company from inception through a third party financing. The Fortress Note is due on demand and accrues interest of 8% per year, with interest due and
principal due upon demand. This line of credit can be pre-paid at any time in cash or through Fortress’ indebtedness to NSC Biotech Venture Fund I, LLC (“NSC Note”) or
other similar indebtedness.

At  December  31,  2016,  the  Fortress  Note  was  approximately  $320,000  and  was  recorded  as  note  payable  -  related  party  on  the  Balance  Sheets.  The  Company  recognized
approximately $253,000 and $168,000 in interest expense at 8% on the Statements of Operations for the year ended December 31, 2016 and for the period from March 13, 2015
(inception) to December 31, 2015, respectively. The Fortress Note was paid in full during the first quarter of 2017.

NSC Note

MUSTANG BIO, INC.
Notes to Financial Statements

In March 2015, Fortress closed a private placement of a promissory note for $10 million through National Securities Corporation (“NSC”). Fortress used the proceeds from the
NSC Note to acquire medical technologies and products. The note matures in 36 months, provided that during the first 24 months Fortress can extend the maturity date by six
months. No principal amount will be due for the first 24 months (or the first 30 months if the maturity date is extended). Thereafter, the note will be repaid at the rate of 1/12 of
the principal amount per month for a period of 12 months. Interest on the note is 8% payable quarterly during the first 24 months (or the first 30 months if the note is extended)
and monthly during the last 12 months. NSC, is a wholly owned subsidiary of National Holdings, Inc., acted as the sole placement agent for the NSC Note.

The NSC Note was amended and restated on July 29, 2015, to provide that any time a Fortress Company receives from Fortress any proceeds from the NSC Note, Fortress
may, in its sole discretion, cause the Fortress Company to issue to NSC Biotech Venture Fund I LLC a new promissory note (the “Amended NSC Note”) on identical terms as
the NSC Note (giving effect to the passage of time with respect to maturity). The Amended NSC Note will equal the dollar amount of the Fortress Company’s share of the NSC
Note and reduce the Fortress’ obligations under the NSC Note by such amount. Fortress will guarantee the Amended NSC Note until the Company completes an initial public
offering.

If the Company has an initial public offering and raises sufficient equity capital so that it has cash equal to five times the amount of the portion of the proceeds of the NSC Note
transferred to it, then NSC will receive a warrant to purchase the Company’s stock equal to 25% of the outstanding note divided by the lowest price the Company sells its equity
in its first third party financing. The warrants issued will have a term of 10 years and an exercise price equal to the par value of the Company’s common stock.

On July 5, 2016, Fortress transferred $3.6 million of the Company’s indebtedness, with a debt discount related to the Company’s pro rata share of Fortress’ debt issuance costs
of approximately $129,000, under the Fortress Note to its NSC Note as well as a contingently issuable warrant equal to 25% of the transferred indebtedness. For the year ended
December 31, 2016, the Company recorded costs of approximately $763,000 related to the amortization of the debt discount and approximately $140,000 of interest expense at
8%,  both  recorded  in  interest  expense  on  the  Statements  of  Operations.  The  effective  interest  rate  of  the  NSC  Note  approximates  23.1%.  The  detachable  Warrant  issued  in
connection with NSC Note in the amount of approximately $634,000 was recorded as a debt discount based on its fair value (see Note 6).

Pursuant to the terms of the Company’s $3.6 million Amended NSC Note, upon the closing of the Company’s second round of financing on October 25, 2016, the Company
issued to National warrants for 138,462 relating to its aggregate gross proceeds from its third party offerings exceeding five times the value of the debt. Upon the issuance of the
warrant Fortress was removed as the guarantor on the note. In December 2016, the NSC Note was fully paid off.

If the Company has an initial public offering and raises sufficient equity capital so that it has cash equal to five times the amount of the portion of the proceeds of the NSC Note
transferred to it, then NSC will receive a warrant to purchase the Company’s stock equal to 25% of the outstanding note divided by the lowest price the Company sells its equity
in its first third party financing. The warrants issued will have a term of 10 years and an exercise price equal to the par value of the Company’s common stock.  In accordance
with ASC 815, the Company classifies the fair value of the warrant that may have been granted in connection with the NSC Note transferred to the Company as a derivative
liability as there was a potential that the Company would not have a sufficient number of authorized common shares available to settle this instrument. The Company valued
this  warrant  using  a  Black-Scholes  model  and  used  estimates  for  an  expected  dividend  yield,  a  risk-free  interest  rate,  and  expected  volatility  together  with  management’s
estimate of the probability of issuance of the warrant. At each reporting period, as long as the warrant was potentially issuable and there was a potential for an insufficient
number of authorized shares available to settle the warrant, the warrant was revalued and any difference from the previous valuation date would be recognized as a change in
fair value in the Company’s Statements of Operations.

In the fourth quarter of 2016, due to the financings described in Note 8, sufficient equity capital was raised so that the Company had cash equal to five times the amount of the
portion of the proceeds of the NSC Note transferred to it. The Company issued 138,462 warrants with an exercise price of par value and a ten year term.

On January 15, 2016, Dr. Winson Tang (“Plaintiff”) filed a Complaint against the Company in the Superior Court of the State of California, County of Los Angeles.  Winson
Tang v. Lindsay Rosenwald et al, Case No. BC607346.  As amended, the complaint alleges that Dr. Tang was a third-party beneficiary of the Company's Exclusive License
Agreement with COH and should be declared the owner of 15% of the Company's outstanding shares.   After the Company and other defendants demurred, the Court sustained
the  demurrer  and  dismissed  all  claims  without  prejudice  on  September  13,  2016.    Dr.  Tang  filed  his  second  amended  complaint  on  October  11,  2016,  and  the  court  again
sustained the demurrer without prejudice, except for a claim for declaratory relief against the Company.  Subsequently, Dr. Tang agreed to narrow his claims and drop certain
defendants from the case.  Dr. Tang filed his third amended complaint on January 17, 2017, alleging one claim for declaratory relief against the Company and two claims for
breach of contract against certain other Defendants. Defendants filed their answer on February 23, 2017, denying Tan has any rights to recovery. The parties are proceeding
with discovery, and the case is set for trial on November 6, 2017. 

As  of  December  31,  2016,  the  Company  has  not  accrued  any  losses  in  connection  with  this  litigation  as  the  Company  believes  that  Plaintiff's  claims  are  without  merit  and
intends to vigorously defend this lawsuit.  Even in the event of an adverse determination, Fortress and the Company intend to satisfy any judgment from sources other than
newly issued shares of the Company to prevent dilution.

Note 8 — Stockholders’ Equity (Deficit)

Common Stock

The Company, in accordance with its certificate of incorporation, as amended in July 2016, which was retroactively applied, is authorized to issue 50,000,000 common shares
with  a  par  value  of  $0.0001  per  share,  of  which  1,000,000  shares  are  designated  as  “Class A  Common  Stock”  and  15,000,000  shares  are  designated  as  “Class  B  Common
Stock”.

In connection with the Company’s formation, Fortress subscribed for 7,000,000 shares of the Class B Common Stock and 2,000,000 shares of the Company’s Common Stock,
pursuant to the Founders Agreement. Fortress paid the par value of $900 in 2016. The fair value of the Company’s common shares approximated par value as no licenses had
been transferred at that time. Dividends, if and when declared, are to be distributed pro-rata to the Class A, B and Common Stock holders.

Notes to Financial Statements

The holders of Common Stock are entitled to one vote per share of Common Stock held. The holders of Class A Common Stock are entitled to the number of votes equal to the
number of whole shares of Common Stock into which the shares of Class A Common Stock held by such holder are convertible and for a period of ten years from its issuance,
the holders of the Class A Common Stock have the right to appoint one member of the board of directors of Mustang; to date, the holders of Class A Common Stock have not
yet appointed such director.

The Class B Common Stockholders are entitled, for each share of Class B Common Stock held, to a number of votes equal to 1.1 times a fraction, the numerator of which is the
sum of (A) the shares of outstanding Common Stock and (B) the whole shares of Common Stock into which the shares of outstanding Class A Common Stock and the Class B
Common Stock are convertible and the denominator of which is the number of shares of outstanding Class B common shares.

Pursuant to the Founders Agreement, on March 13, 2016 the Company issued 250,000 shares of Class B Common Stock to Fortress, which equaled 2.5% of the fully diluted
outstanding equity of Mustang at the time of issuance for the annual equity fee (see Note 4).

Class A Common Shares

On March 17, 2015, the Company entered into an exclusive license agreement with COH to acquire intellectual property rights pertaining to CAR-T. Pursuant to the agreement,
the Company paid COH an upfront fee of $2.0 million, in April 2015 (included in research and development-licenses acquired expenses on the Statements of Operations), and
granted 1,000,000 shares of Mustang’s Class A Common Stock, representing 10% ownership of Mustang, as of such date. As of December 31, 2016, the City of Hope owns
1,000,000 Class A common shares.

Exchange of Class B Common Shares and Class A Preferred Shares

In accordance with the amended and restated certificate of incorporation filed on July 27, 2016, the Company issued 250,000 shares of Class A Preferred Stock, 7.0 million
common shares and cancelled 7.2 million Class B common shares. This exchange was recorded as an equity transaction and therefore no gain or loss was recorded.

Offerings and Issuances of Common Stock and Warrants

In September 2016, the Company entered into a Placement Agent Agreement with NSC relating to the Company’s offering of shares of Common Stock in a private placement.
Pursuant to the Placement Agent Agreement, the Company agreed to pay the Placement Agent a cash fee of 10.0% of the gross proceeds from the offering and granted a warrant

Class A Preferred Shares

Pursuant to the Company’s Amended and Restated Articles of Incorporation, filed on July 26, 2016, Class B Common Stock was eliminated and 2,000,000 shares of Preferred
Stock were authorized, of which 250,000 have been designated as Class A Preferred Stock and the remainder are undesignated preferred stock. The Class A Preferred Stock is
identical to undesignated Common Stock other than as to voting rights, conversion rights, and the PIK Dividend right (as described below). The undesignated Preferred Stock
may be issued from time to time in one or more series. The Company’s Board of Directors is authorized to determine or alter the dividend rights, dividend rate, conversion
rights,  voting  rights,  rights  and  terms  of  redemption  (including  sinking  fund  provisions,  if  any),  the  redemption  price  or  prices,  the  liquidation  preferences  and  other
designations, powers, preferences and relative, participating, optional or other special rights, if any, and the qualifications, limitations and restrictions granted to or imposed
upon any wholly unissued series of Preferred Stock, and to fix the number of shares of any series of Preferred Stock (but not below the number of shares of any such series then
outstanding).

The holders of the outstanding shares of Class A Preferred Stock shall receive on each March 13 (each a “PIK Dividend Payment Date”) after the original issuance date of the
Class A Preferred Stock until the date all outstanding Class A Preferred Stock is converted into Common Stock or redeemed (and the purchase price is paid in full), pro rata per
share dividends paid in additional fully paid and nonassessable shares of Common Stock (such dividend being herein called “PIK Dividends”) such that the aggregate number
of shares of Common Stock issued pursuant to such PIK Dividend is equal to 2.5% of the Corporation’s fully-diluted outstanding capitalization on the date that is one business
day prior to any PIK Dividend Payment Date (“PIK Record Date”). In the event the Class A Preferred Stock converts into Common Stock, the holders shall receive all PIK
Dividends accrued through the date of such conversion. No dividend or other distribution shall be paid, or declared and set apart for payment (other than dividends payable
solely in capital stock on the capital stock of the Company) on the shares of Common Stock until all PIK Dividends on the Class A Preferred Stock shall have been paid or
declared and set apart for payment. All dividends are non-cumulative.

On  any  matter  presented  to  the  stockholders  of  the  Company  for  their  action  or  consideration  at  any  meeting  of  stockholders  of  the  Company  (or  by  written  consent  of
stockholders in lieu of meeting), each holder of outstanding shares of Class A Preferred Stock shall be entitled to cast for each share of Class A Preferred Stock held by such
holder  as  of  the  record  date  for  determining  stockholders  entitled  to  vote  on  such  matter,  the  number  of  votes  that  is  equal  to  one  and  one-tenth  (1.1)  times  a  fraction,  the
numerator of which is the sum of (A) the number of shares of outstanding Common Stock and (B) the whole shares of Common Stock in to which the shares of outstanding
Class A Common Stock and the Class A Preferred Stock are convertible, and the denominator of which is number of shares of outstanding Class A Preferred Stock (the “Class
A Preferred Stock Ratio”). Thus, the Class A Preferred Stock will at all times constitute a voting majority.

Each  share  of  Class A  Preferred  Stock  is  convertible,  at  the  option  of  the  holder,  into  one  fully  paid  and  nonassessable  share  of  Common  Stock  (the  “Conversion  Ratio”),
subject  to  certain  adjustments.  If  the  Company,  at  any  time  effects  a  subdivision  or  combination  of  the  outstanding  Common  Stock  (by  any  stock  split,  stock  dividend,
recapitalization, reverse stock split or otherwise), the applicable Conversion Ratio in effect immediately before that subdivision is proportionately decreased or increased, as
applicable, so that the number of shares of Common Stock issuable on conversion of each share of Class A Preferred Stock shall be increased or decreased, a applicable, in
proportion to such increase or decrease in the aggregate number of shares of Common Stock outstanding. Additionally, if any reorganization, recapitalization, reclassification,
consolidation or merger involving the Company occurs in which the Common Stock (but not the Class A Preferred Stock) is converted into or exchanged for securities, cash or
other property, then each share of Class A Preferred Stock becomes convertible into the kind and amount of securities, cash or other property which a holder of the number of
shares  of  Common  Stock  of  the  Company  issuable  upon  conversion  of  one  share  of  the  Class A  Preferred  Stock  immediately  prior  to  such  reorganization,  recapitalization,
reclassification, consolidation or merger would have been entitled to receive pursuant to such transaction.

For financial reporting purposes, the Company calculated income tax provision and deferred income tax balances as if it was a separate entity and had filed its own separate tax
return under Sub-chapter C of the Internal Revenue Code.

A reconciliation of the statutory U.S. federal rate to the Company’s effective tax rate is as follows:

Statutory federal income tax rate
State taxes, net of federal tax benefit
Non-deductible items
Credits
Rate change
Other
Change in valuation allowance

The Company has determined, based upon available evidence, that it is more likely than not that the net deferred tax asset will not be realized and, accordingly, has provided a
full valuation allowance against its net deferred tax asset. A valuation allowance of approximately $7.6 million and $1.7 million, respectively, was recorded for the year ended
December 31, 2016 and the period from March 13, 2015 (inception) through December 31, 2015.

Notes to Financial Statements

As of December 31, 2016, the Company had federal and state net operating loss carryforwards of approximately $7.3 million and $13.5 million, respectively. The federal and
state net operating loss carryforwards will begin to expire, if not utilized, by 2035 and 2025, respectively. Utilization of the net operating loss carryforward may be subject to an
annual limitation due to the ownership change limitations provided by Section 382 of the Internal Revenue Code of 1986, as amended and similar state provisions.

There are no significant items determined to be unrecognized tax benefits taken or expected to be taken in a tax return, in accordance with ASC 740 “Income Taxes” (“ASC
740”), which clarifies the accounting for uncertainty in income taxes recognized in the financial statements, that have been recorded on the Company’s financial statements for
the period ended December 31, 2016. The Company does not anticipate a material change to unrecognized tax benefits in the next twelve months.

Additionally, ASC 740 provides guidance on the recognition of interest and penalties related to income taxes. There were no interest or penalties related to income taxes that
have been accrued or recognized as of and for the period ended December 31, 2016.

The federal and state tax returns for the periods ended December 31, 2016 and 2015 are currently open for examination under the applicable federal and state income tax statues
of limitations.

NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are

hereby acknowledged, the Parties hereto agree as follows:

1.             Board Advisory Services.

1.1            Approval and Authority. Where not required by applicable law or regulation, the Advisor shall not require the prior approval of the Board to
perform its duties under this Agreement. Notwithstanding the foregoing, the Advisor shall not have the authority to bind the Company, and nothing contained herein shall be
construed to create an agency relationship between the Company and the Advisor.

1.1           Services.

1.1.1        Scope. Subject to any limitations imposed by applicable law or regulation, the Advisor shall render or cause to be rendered board advisory
services  to  the  Company,  which  services  may  include,  without  limitation,  participation  on  the  Board  of  the  Company  in  the  capacity  of  Chairman  of  the  Board  by  one  of
Advisor’s employees and related advice and assistance by Advisor and its employees (collectively, the “ Services”). The Advisor shall provide and devote to the performance of
this Agreement such employees, Affiliates and agents of the Advisor as the Advisor shall deem appropriate to the furnishing of the Services hereunder, which employees (other
than Mr. Weiss) shall be billed separately (quarterly in arrears) at the hourly rates designated on Schedule 1.1.1. Such billings shall not exceed $10,000 per year without prior
authorization of the Company. “Affiliate” means a person or entity that controls, is controlled by or is under common control with a party, but only for so long as such control
exists.  For  the  purposes  of  the  definition  of Affiliate,  the  word  “control”  (including,  with  correlative  meaning,  the  terms  “controlled  by”  or  “under  common  control  with”)
means  the  actual  power,  either  directly  or  indirectly  through  one  or  more  intermediaries,  to  direct  the  management  and  policies  of  such  person  or  entity,  whether  by  the
ownership of at least 50% of the voting stock of such entity, or by contract or otherwise.

1 

 
 
 
 
 
 
 
 
 
 
 
1.1.2         Board Services. The Company hereby requests and Advisor hereby agrees to provide Mr. Weiss to serve as Chairman of the Board of the
Company. In order to enable Advisor to provide Mr. Weiss, one of its employees, to deliver the requested Services as Chairman of the Board of the Company, the Company
agrees to use its best efforts to cause Michael S. Weiss, to be elected as a member of the Company’s Board, and to be selected as Chairman of the Board, throughout the Term
and shall include him in the slate for election as a director at every stockholders meeting during the Term at which his term as a director would otherwise expire.

1.2           Non-exclusivity, Freedom to Pursue Opportunities and Limitation on Liability.

1.2.1        Non Exclusivity. The Advisor shall devote such time and efforts to the performance of Services contemplated hereby as the Advisor deems
reasonably necessary or appropriate; provided, however, that no minimum number of hours is required to be devoted by the Advisor on a weekly, monthly, annual or other
basis. The Company acknowledges that the Services are not exclusive to the Company and that the Advisor will render similar Services to other persons and entities.

1.2.2         Freedom to Pursue Opportunities.  In  recognition  that  the Advisor  and  its Affiliates  currently  have,  and  will  in  the  future  have  or  will
consider  working  with  or  investing  in  numerous  companies  with  respect  to  which  the Advisor  or  its Affiliates  may  serve  as  an  advisor,  a  director,  officer  or  in  some  other
capacity, and in recognition that the Advisor and its Affiliates have a myriad of duties to these other companies and their shareholders, and in anticipation that the Company and
the Advisor (or one or more Affiliates or clients of the Advisor) may engage in the same or similar activities or lines of business and have an interest in the same areas of
corporate opportunities, and in recognition of the benefits to be derived by the Company hereunder and in recognition of the difficulties that may confront any Advisor who
desires and endeavors fully to satisfy such Advisor’s duties in determining the full scope of such duties in any particular situation, the provisions of this  Section 1.2.2 are set
forth to regulate, define and guide the conduct of certain affairs of the Company as they may involve the Advisor.

Except as the Advisor may otherwise agree in writing after the date hereof:

(i) the Advisor will have the right: (A) to directly or indirectly engage in any business including, without limitation, any business activities or lines of business that are
the same as or similar to those pursued by, or competitive with, any of the Company’s, (B) to directly or indirectly do business with any client or customer of the Company, (C)
to take any other action that the Advisor believes in good faith is necessary to or appropriate to fulfill its obligations as described in the first sentence of this  Section 1.2.2, and
(D) not to present potential transactions, matters or business opportunities to the Company, and to pursue, directly or indirectly, any such opportunity for itself, and to direct any
such opportunity to another person.

(ii) the Advisor and its officers, employees, partners, members, other clients, Affiliates and other associated entities will have no duty (contractual or otherwise) to
communicate  or  present  any  corporate  opportunities  to  the  Company  or  to  refrain  from  any  action  specified  in Section 1.2.2(i),  and  the  Company  on  its  own  behalf  and  on
behalf of its Affiliates, hereby renounces and waives any right to require the Advisor or any of its Affiliates to act in a manner inconsistent with the provisions of this  Section
1.2.2.

2 

 
 
 
 
 
 
 
 
 
(iii)  Neither  the Advisor  nor  any  officer,  director,  employee,  partner,  member,  stockholder, Affiliate  or  associated  entity  thereof  will  be  liable  to  the  Company  for
breach of any duty (contractual or otherwise) by reason of any activities or omissions of the types referred to in this Section 1.2.2 or of any such person’s participation therein.

2.              Term. The Advisor shall provide the Services set forth in Section 1 above from the date hereof until the earlier of (a) termination of this Agreement by
mutual agreement of the Advisor and the Company and (b) the date on which Advisor is no longer a member of the Board of the Company (such period, the “ Term”). If this
Agreement is terminated as a result of (i) the Board not nominating Advisor for reelection to the Board or (ii) the shareholders not voting to reelect Advisor to the Board, then
any outstanding but unvested equity grants shall immediately vest.

No termination of this Agreement, whether pursuant to this Section 2 or otherwise, will affect the Company’s duty to pay any Management Fee (as defined
herein in Section 3) accrued, or to reimburse any cost or expense incurred pursuant to Section 4 hereof, prior to the effective date of such termination. Upon termination of this
Agreement,  the  Advisor’s  right  to  receive  any  further  Management  Fee  or  reimbursement  for  costs  and  expenses  that  have  not  accrued  or  been  incurred  to  the  date  of
termination shall cease and terminate. Additionally, the obligations of the Company under  Section 4  (Expenses), Section 7 (Indemnification), the provisions of Section  1.2.2
above (whether in respect of or relating to Services rendered prior to termination of this Agreement or in respect of or relating to any Services provided after termination of this
Agreement) and the provisions of Section 14 (Governing Law) will also survive any termination of this Agreement to the maximum extent permitted under applicable law.

3.             Compensation.

3.1           Commencing on the date hereof, in consideration of the board advisory and consulting services to be rendered, the Company will pay to the Advisor
an annual consulting fee in cash in the aggregate amount equal to $60,000 (the “Annual Consulting Fee”), payable in advance in equal quarterly installments within twenty (20)
business days of the beginning of each calendar quarter in each year. In addition, Advisor shall receive any and all annual equity incentive grants paid to other members of the
Board of Directors, as, if and when paid to the other Board members.

accounts as designated from time-to-time by the Advisor to the Company in writing or (ii) by corporate check delivered by U.S. mail or overnight delivery service.

3.2            Any payment pursuant to this Section 3 shall be made either (i) in cash by wire transfer(s) of immediately available funds to or among one or more

4.              Expenses. Actual and direct out-of-pocket expenses reasonably incurred by the Advisor and its personnel in performing the Services shall be reimbursed to
the Advisor by the Company upon the delivery to the Company of an invoice, receipt or such other supporting data as the Company reasonably shall require. The Company
shall reimburse the Advisor by wire transfer of immediately available funds or by corporate check for any amount paid by the Advisor, which shall be in addition to any other
amount payable to the Advisor under this Agreement.

5.             Reserved.

6.             Decisions and Authority of the Advisor.

6.1            No Liability. In no event will the Advisor or any of its Affiliates be liable to the Company for any indirect, special, incidental or consequential
damages, including, without limitation, lost profits or savings, whether or not such damages are foreseeable, or for any third party claims (whether based in contract, tort or
otherwise), relating to the Services to be provided by the Advisor hereunder. The Company reserves the right to make all decisions with regard to any matter upon which the
Advisor has rendered advice and consultation, and there shall be no liability of the Advisor for any such advice accepted by the Company pursuant to the provisions of this
Agreement. The Advisor will not be liable for any mistakes of fact, errors of judgment or losses sustained by the Company or for any acts or omissions of any kind (including
acts or omissions of the Advisor), except to the extent caused by intentional misconduct of the Advisor as finally determined by a court of competent jurisdiction. In such case,
the Advisor’s liability shall be limited to direct damages not to exceed the total fees paid to Advisor for the Services provided to the Company through the date of any claim.

6.2           

Independent Contractor.  The Advisor  shall  act  solely  as  an  independent  contractor  and  shall  have  complete  charge  of  its  respective  personnel
engaged  in  the  performance  of  the  Services  under  this Agreement.  Neither  the Advisor  nor  its  officers,  employees  or  agents  will  be  considered  employees  or  agents  of  the
Company or any of its respective subsidiaries as a result of this Agreement. As an independent contractor, the Advisor shall have authority only to act as an advisor to the
Company and shall have no authority to enter into any agreement or to make any representation, commitment or warranty binding upon the Company or to obtain or incur any
right,  obligation  or  liability  on  behalf  of  the  Company.  Nothing  contained  in  this Agreement  shall  result  in  the Advisor  or  any  of  its  partners  or  members  or  any  of  their
Affiliates, investment Advisors, investment advisors or partners being a partner of or joint venturer with the Company.

7.             Indemnification.

7.1            Indemnification. The Company shall (i) indemnify the Advisor and its respective Affiliates, directors, officers, employees and agents (collectively,
the “Indemnified Party”), to the fullest extent permitted by law, from and against any and all actions, causes of action, suits, claims, liabilities, losses, damages and costs and
expenses in connection therewith, including without limitation reasonable attorneys’ fees and expenses (“Indemnified Liabilities”) to which the Indemnified Party may become
subject,  directly  or  indirectly  caused  by,  related  to  or  arising  out  of  the  Services  or  any  other  advice  or  Services  contemplated  by  this Agreement  or  the  engagement  of  the
Advisor pursuant to, and the performance by such Advisor of the Services contemplated by, this Agreement, and (ii) promptly reimburse the Indemnified Party for Indemnified
Liabilities as incurred, in connection with the investigation of, preparation for or defense of any pending or threatened claim or any action or proceeding arising therefrom,
whether or not such Indemnified Party is a party and whether or not such claim, action or proceeding is initiated or brought by or on behalf of the Company or Advisor and
whether  or  not  resulting  in  any  liability.  If  and  to  the  extent  that  the  foregoing  undertaking  may  be  unenforceable  for  any  reason,  the  Company  hereby  agrees  to  make  the
maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable law.

4 

 
 
 
 
 
 
 
 
7.2           Limitations on Indemnity; Restrictions on Liability. The Company shall not be liable under the indemnification contained in Section 7.1 hereof with
respect to the Indemnified Party to the extent that such Indemnified Liabilities are found in a final non-appealable judgment by a court of competent jurisdiction to have resulted
directly from the Indemnified Party’s willful misconduct. The Company further agrees that no Indemnified Party shall have any liability (whether direct or indirect, in contract,
tort or otherwise) to the Company, holders of its securities or its creditors related to or arising out of the engagement of the Advisor pursuant to, or the performance by the
Advisor of the Services contemplated by, this Agreement.

8.              Notices. All notices, demands, or other communications to be given or delivered under or by reason of the provisions of this Agreement shall be in writing
and shall be deemed to have been given or made when (i) delivered personally to the recipient, (ii) telecopied to the recipient (with a hard copy sent to the recipient by reputable
overnight  courier  service  (charges  prepaid))  if  telecopied  before  5:00  p.m.  Eastern  Standard  Time  on  a  business  day,  and  otherwise  on  the  next  business  day,  (iii)  one  (1)
business  day  after  being  sent  to  the  recipient  by  reputable  overnight  courier  service  (charges  prepaid)  or  (iv)  received  via  electronic  mail  by  the  recipient  if  received  via
electronic  mail  before  5:00  p.m.  Eastern  Standard  Time  on  a  business  day,  and  otherwise  on  the  next  business  day  after  such  receipt.  Such  notices,  demands  and  other
communications  shall  be  sent  to  the  address  for  such  recipient  indicated  below  or  to  such  other  address  or  to  the  attention  of  such  other  person  as  the  recipient  party  has
specified by prior written notice to the sending party.

by both the Company and the Advisor. No waiver on any one occasion will extend to, effect or be construed as a waiver of any right or remedy on any future occasion. No

Agreement to any of its Affiliates.

14.            Governing Law. This Agreement shall be governed by and construed in accordance with the substantive laws of the state of Delaware, without giving effect

to any choice of law or conflict of law provision or rule that would cause the application of the laws of any jurisdiction other than the state of Delaware.

intent  or  interpretation  arises,  this Agreement  will  be  construed  as  if  drafted  jointly  by  the  Parties  hereto,  and  no  presumption  or  burden  of  proof  will  arise  favoring  or
disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement.

EXCLUSIVE LICENSE AGREEMENT

THIS EXCLUSIVE LICENSE AGREEMENT AND THE ATTACHED APPENDICES A, B, C, AND D (collectively, the “ Agreement”) is made and is effective as of March
17,  2017  (the  “Effective Date”)  between THE  REGENTS  OF  THE  UNIVERSITY  OF  CALIFORNIA  (“The  Regents”),  a  California  corporation  having  its  corporate

located at 10889 Wilshire Boulevard, Suite 920, Los Angeles, CA 90095-7191 , and MUSTANG BIO, INC. (“Licensee”), a Delaware corporation having a principal place of
business at 2 Gansevoort, 9th Floor, New York, NY 10014.

WHEREAS, certain invention(s), generally characterized as

RECITALS

1. UCLA Case No. * : “Engineered Anti-Prostate Stem Cell Antigen (PSCA) Antibodies for Cancer Targeting”; and

2. UCLA Case No. * : “High Affinity Anti-Prostate Stem Cell Antigen (PSCA) Antibodies for Cancer Targeting and Detection”

(the “Inventions”) were made in the course of research at the University of California, Los Angeles by Anna Wu, Robert E. Reiter, Eric J. Lepin, James D. Marks, and Yu
Zhou, (“Inventors”), and are claimed in Regents’ Patent Rights, as defined below;

WHEREAS, the Inventors are employees of The Regents and as such are obligated to assign their right, title and interest in and to the Inventions to The Regents;

WHEREAS, UCLA Case Nos. * and * were developed with United States Government funds, and The Regents has elected title thereto and granted royalty-free nonexclusive
licenses to the United States Government on March 6, 2009 and March 5, 2010, respectively, as required under 35 U.S.C. §200-212;

WHEREAS, Licensee is a “small business concern” as defined in 15 U.S.C. §§632; and

WHEREAS, The Regents wishes that Regents’ Patent Rights be developed and utilized to the fullest extent so that the benefits can be enjoyed by the general public.

The parties agree as follows:

1.      DEFINITIONS

1.1

“Affiliate” means any business entity in which Licensee owns or controls, directly or indirectly, at least fifty percent (50%) of the outstanding stock or other voting
rights entitled to elect directors. In any country where the local law does not permit foreign equity participation of at least fifty percent (50%), then “Affiliate” means
any business entity in which Licensee owns or controls, directly or indirectly, the maximum percentage of outstanding stock or voting rights that is permitted by local
law.

1.5

1.6

1.7

1.8

1.9

1.10

“BLA” means a biologics license application submitted to the FDA prior to marketing a pharmaceutical product as required under the United States Federal Food, Drug
and Cosmetic Act and the regulations promulgated thereunder, or the substantive equivalent of such BLA as required by a given Regulatory Authority outside the United
States prior to marketing and selling a pharmaceutical product in such Regulatory Authority’s country.

“Combination Product” means a product which comprises (a) a Licensed Product (the “Licensed Product Component”), and (b) at least one other pharmacologically
active ingredient, which, if administered or used independently of the Licensed Product, would have a therapeutic effect (the “Non-Licensed Product Component”).
Combination Products are also Licensed Products and therefore references to Licensed Products in the definitions in this Agreement (such as in the definition of Net
Sales, Final Sales, etc.) also refer to Combination Products.

“Commercialization” has the meaning set forth in Paragraph 6.1 of this Agreement.

“Commercially  Reasonable  Efforts”  means,  with  respect  to  the  efforts  to  be  expended  pertaining  to  the  commercialization  of  a  Licensed  Product,  those  diligent,
reasonable,  good  faith  efforts  to  accomplish  such  objective  as  such  party  would  normally  use  to  accomplish  a  similar  objective  under  similar  circumstances.  For  the
avoidance of doubt, "Commercially Reasonable Efforts" shall not include (a) halting commercialization of, or otherwise shelving, a Licensed Product for the purpose of
pursuing another of Licensee's (or Sublicensee's as the case may be) products not covered by Regents' Patent Rights or (b) discontinuing all development, manufacturing,
marketing and selling of such Licensed Product for a period of greater than twenty-four (24) months.

“Covered” means that the use, manufacture, sale, offer for sale, development, commercialization or importation of the subject matter in question by an unlicensed entity
would infringe a Valid Claim of a Patent Right; provided that infringement of any Valid Claim of a pending patent application shall be determined as if such Valid Claim
were issued or granted.

“Customer” means any individual or entity that receives Licensed Products or Licensed Methods, provided however, that Licensee or Sublicensee shall be deemed a
Customer only if it receives Licensed Products or Licensed Methods that are not intended for further sale, transfer, lease, exchange or other disposition.

“FDA” means the United States Food and Drug Administration or any successor entity thereto.

“Field of Use” *.

“Final Sale” means any sale, transfer, lease, exchange or other disposition or provision of a Licensed Product and/or a Licensed Method to a Customer by Licensee or a
Sublicensee.  A Final Sale will be deemed to have occurred upon the earliest to occur of the following (as applicable): (a) the transfer of title to such Licensed Product
and/or  Licensed  Method  to  a  Customer,  (b)  the  shipment  of  such  Licensed  Product  to  a  Customer,  (c)  the  provision  of  a  Licensed  Method  to  a  Customer,  (d)  the
provision of an  invoice  for  such  Licensed  Product  or  Licensed  Method  to  a  Customer,  or  (e)  payment  by  the  Customer  for  Licensed  Products  or  Licensed  Methods.
Exchange of Licensed Products between Licensee and a Sublicensee is not a Final Sale if the Licensed Product is intended for further sale, transfer, lease, exchange or
other disposition, in which case the Final Sale will be deemed to have occurred upon sale, transfer, lease, exchange or other disposition or provision of Licensed Product

required  under  the  United  States  Federal  Food,  Drug  and  Cosmetic  Act  and  the  regulations  promulgated  thereunder,  or  the  substantive  equivalent  of  such  IND
application as required by a given Regulatory Authority outside the United States prior to commencing clinical testing of a pharmaceutical product in human subjects in
such Regulatory Authority’s country.

“Joint Venture” means any separate entity established pursuant to an agreement between a third party and Licensee and/or a Sublicensee, in which the separate entity
manufactures, uses, purchases, sells or acquires Licensed Products from Licensee or a Sublicensee.

If the Licensed Product or Licensed Method is a component of a Combination Product, such Combination Product is deemed to be the Licensed Product for purposes of
this Agreement.

Likewise, if Licensee or a Sublicensee receives a Licensed Product for incorporation into another product intended for sale, transfer, lease or other disposition, then, for
the  purposes  of  this Agreement,  the  Licensed  Product  is  such  product  intended  for  sale,  transfer,  lease,  or  other  disposition  by  Licensee  or  a  Sublicensee,  and  such
product intended for sale, transfer, lease, or other disposition by Licensee or a Sublicensee is also a Combination Product for purposes of this Agreement.

immediately preceding ten (10) years, the proration factor shall be determined by the formula [A/(A+B)], where A is the average over the past ten years of the
gross selling price of the Licensed Product Component sold separately and B is the average over the past ten years of the gross selling price of the Non-Licensed
Product Component(s);

1.18b If the Licensed Product Component(s) and the Non-Licensed Product Component(s) were not both sold separately from each other during one or more of the
immediately preceding ten (10) years but the Licensed Product Component was sold separately during one or more of the immediately preceding ten (10) years,
the proration factor shall be determined by the formula A/C, where A is the average over the past ten (10) years of the gross selling price of the Licensed Product
Component sold separately, and C is the invoice price of the Combination Product. 

1.18c

If neither 1.18a or 1.18b applies, then the proration factor shall be determined in a consistent and equitable manner that reflects the contribution of the Licensed
Product Component to the payments received from Net Sales of the Combination Product as the parties shall in good faith negotiate and agree.

Subject to the limitations set forth in this Agreement, The Regents hereby grants to Licensee, and Licensee hereby accepts an exclusive (even as to The Regents, subject
to Paragraph 2.3) license (with rights to sublicense as further described in Paragraph 3.1) (the “License”) under Regents’ Patent Rights, in jurisdictions where Regents’
Patent  Rights  exist,  to  make,  have  made,  use,  sell,  offer  for  sale  and  import  Licensed  Products  and  to  practice  Licensed  Methods  in  the  Field  of  Use  to  the  extent
permitted by law. Licensee will not make, use, have made, sell, offer for sale, or import Licensed Products or practice Licensed Methods outside the Field of Use. For
the avoidance of doubt, Affiliates and Joint Ventures have no rights hereunder unless granted a Sublicense.

The  License  is  subject  to  all  the  applicable  provisions  of  any  license  to  the  United  States  Government  executed  by  The  Regents  and  is  subject  to  any  overriding
obligations  to  the  United  States  Federal  Government  under  35  U.S.C.  §§200-212,  applicable  governmental  implementing  regulations,  and  the  U.S.  Government
sponsored research agreement or other guidelines.

The  Regents  expressly  reserves  the  right  to:  (a)  use  Regents’  Patent  Rights  and  associated  technology  for  educational  and  research  purposes,  clinical  research,  (b)
publicly  disclose  research  results,  (c)  use  Regents’  Patent  Rights  and  associated  technology  to  offer  and  perform  clinical  diagnostic  and  prognostic  services,  and  (d)
allow other non-profit institutions to use Regents’ Patent Rights and associated technology for the same purposes as all of the foregoing.

If Licensee files a claim including in any way the assertion that any portion of Regents’ Patent Rights is invalid or unenforceable where the filing is by Licensee, a third
party on behalf of Licensee, or a third party at the written urging of, or with the deliberate assistance of, the Licensee, then, if such challenge fails, the royalty rate due
hereunder will immediately double with no further notice from The Regents (any such action, a “Patent Challenge”). The Parties agree, however, that, notwithstanding
the foregoing, the following actions or filings shall not constitute a Patent Challenge for purposes of this Agreement: (i) arguments and comments made by or on behalf
of Licensee, any Affiliate thereof, or any Sublicensee in its usual course of business with respect to prosecution of Licensee’s, its Affiliates’, or any Sublicensees’ patents
or patent applications in response to communications from patent offices or Regulatory Authorities, provided that such arguments and comments are primarily directed
at differentiating Licensee’s, its Affiliates’, or any Sublicensees’ patents or patent applications as patentably distinct from the Regents’ Patent Rights and not primarily
aimed at questioning or contesting the validity, enforceability, patentability, priority of invention or other claim to priority, or patent term adjustment of the Regents’
Patent Rights; (ii) arguments and comments made by Licensee, any Affiliate thereof, or any Sublicensee in legal proceedings in defense of Licensee’s, its Affiliates’, or
any Sublicensees’ patents or patent applications, but only if an opposing party uses Regents’ Patent Rights to challenge the validity or enforceability of the defended
patents or patent applications of Licensee, any Affiliate thereof, or any Sublicensee, provided that such arguments and comments are primarily directed at differentiating
Licensee’s, its Affiliates’, or Sublicensees’ patents or patent applications as patentably distinct from the Regents’ Patent Rights and not primarily aimed at questioning
or contesting the validity, enforceability, patentability, priority of invention or other claim to priority, or patent term adjustment of the Regents’ Patent Rights; (iii) any
defenses, counterclaims, or countersuits brought by a Sublicensee in response to a legal proceeding filed by or on behalf of Licensor or any licensee, sublicensee, or
transferee thereof with respect to any Regents’ Patent Rights against such Sublicensee with respect to an alleged or actual infringement of Regents’ Patent Rights by such
Sublicensee with respect to a product or service, other than a Product, not intended for use in the Field (or the use or manufacture thereof) and where such Sublicensee
does not expressly question or contest the validity or enforceability of the Regents’ Patent Rights with respect to any Product or any other product or service intended for
use in the Field (or the use or manufacture thereof) (i.e., if such Sublicensee expressly contests the validity or enforceability of the Regents’ Patent Rights with respect to
any Product or other product or service intended for use in the Field (or the use or manufacture thereof) ; (iv) if a non-Affiliate third party Sublicensee withdraws, files a
dismissal  with  prejudice,  or  takes  any  action  having  similar  effect,  with  respect  to  any  action  or  proceeding  commenced  by  such  Sublicensee  in  any  patent  office,
Governmental Authority, or court in which it challenged the validity or enforceability of any Regents’ Patent Rights within  thirty (30) days after the initial filing of such
action or proceeding, and delivers a copy of such withdrawal or dismissal with prejudice, or reasonable documentary evidence of any similar action having similar effect,
to The Regents within such thirty  (30) day period; or (v) any interference, opposition, re-examination or similar proceeding or any other legal proceeding with a patent
office, Regulatory Authority, or any court in which one or more claims or allegations challenges the validity or enforceability of any Regents’ Patent Rights to the extent
the party instituting, maintaining, or furthering such action or proceeding is only actively engaged in the initiation, maintenance, or furthering thereof prior to the date on
which such party became an Affiliate of Licensee or Sublicensee, provided, that such Affiliate files a dismissal with prejudice, or takes any action having similar effect,
with  respect  to  such  action  or  proceeding  commenced  by  such Affiliate  within  thirty  (30)  days  after  becoming  an Affiliate  of  Licensee,  and  delivers  a  copy  of  such

Sublicenses will: (i) be issued in writing, (ii) include an express prohibition against issuing further sublicenses under any or all of Regents’ Patent Rights and (iii) to the
extent applicable include all of the rights of The Regents and require the performance of obligations due to The Regents (and, if applicable, the U.S. Government under

(ROYALTIES) as if these were Licensee’s Net Sales. Any royalties received by Licensee in excess of royalties due to The Regents under this Paragraph 3.3 belong to
Licensee.

Licensee must provide to The Regents a copy of each Sublicense within thirty (30) days of execution and is prohibited from entering into any Side Deal with a third
party where such Side Deal intentionally dilutes, diverts, conceals or misrepresents the amount of consideration paid to the Licensee in consideration for a Sublicense.

Licensee will require that each Sublicensee provide Licensee with reports that are sufficiently detailed to establish all amounts due to The Regents under this Agreement.
Licensee will provide a copy of all such information submitted to Licensee by Sublicensees relevant to the computation of the payments due to The Regents under this
Agreement within thirty (30) days after receipt of such information from such Sublicensee.

enjoyment of any other rights or assets) shall be the corresponding payment obligations set forth in this Agreement;

such Sublicensee delivers to The Regents, within ninety (90) days after termination of this Agreement, a license agreement, executed by such Sublicensee and
proposed thereby for execution by the Regents, that (a) is consistent with the terms and conditions set forth in this Agreement with respect to The Regents’
Patent Rights, as reasonably modified to be no greater in scope than the scope of the Sublicense granted to Sublicensee with respect to territory, duration/term of
the Sublicense, Licensed Products, Field of Use, etc. (e.g. if the Sublicensee's Sublicense, as in effect immediately prior to such termination, included rights and
obligations only with respect to a particular Licensed Product, country in the Territory, and/or indication, the license agreement shall only include rights and
obligations  with  respect  to  such  a  particular  Licensed  Product,  country  in  the  Territory,  and/or  indication)  (such  a  license  agreement,  a  " New  License

November 30 (for any Final Sales that took place on or before the last day of the calendar quarter ending September 30).

5.3

Licensee must pay to The Regents the following minimum annual royalties (referred to below as “Minimum Annual Royalty”) during each of the following calendar
years (measured relative to the calendar year in which there was a First Commercial Sale, and referred to below as “Calendar Years after FCS”) for the life of this
Agreement:

Calendar Years after FCS

* and *
* and *

* Dollars ($ * )
* Dollars ($ * )
* Dollars ($ * )

Licensee must pay the Minimum Annual Royalty for a given Calendar Year after FCS to The Regents on or before February 28 of such Calendar Year after FCS. The
Minimum Annual Royalty for a given Calendar Year after FCS will be credited against the Earned Royalty due and owing with respect to Net Sales made during the
calendar year in which such Minimum Annual Royalty was paid. By way of example, if FCS took place on February 1, 2008, the first Calendar Year After FCS would
be 2009 and the Minimum Annual Royalty would be due on or before February 28, 2009.

5.4

All monies due The Regents must be paid in United States funds. With respect to sales of Licensed Products in a currency other than United States Dollars, the royalties
due The Regents will first be determined in the foreign currency of the country in which the Licensed Products were sold and, second, converted into equivalent United
States Funds by using the applicable conversion rates for buying and selling United States dollars for such foreign currency as published by Reuters on the final business
day of the quarter in which such sales were made.

Any tax for the account of The Regents required to be withheld by Licensee under the laws of any foreign country must be promptly paid by Licensee for and on behalf
of  The  Regents  to  the  appropriate  governmental  authority.  Licensee  will  use  its  best  efforts  to  furnish  The  Regents  with  proof  of  payment  of  any  tax.  Licensee  is
responsible for all bank transfer charges. All payments made by Licensee in fulfilment of The Regents’ tax liability in any particular country will be credited against fees
or royalties due The Regents for that country.

If at any time legal restrictions prevent the acquisition or prompt remittance of United States Dollars by Licensee with respect to any country where a Licensed Product is
sold, Licensee shall pay royalties due to The Regents from Licensee’s other sources of United States Dollars.

If any patent or any claim included in Regents’ Patent Rights is held invalid or unenforceable in a final decision by a court of competent jurisdiction from which no
appeal has or can be taken, all obligation to pay royalties based on that patent or claim or any claim patentably indistinct from it will cease as of the date of that final
decision. Licensee will not, however, be relieved from paying any royalties that accrued before that decision or that is based on another patent or claim not involved in
that decision.

No royalties will be collected or paid on Licensed Products sold to the United States Federal Government or any agency of the United States Government. Licensee and
its Sublicensee will reduce the amount charged for Licensed Products distributed to the United States Government by the amount of the royalty.

For  the  avoidance  of  doubt,  in  no  event  will  the  provisions  of  this  Paragraph  5.9  apply  to  Net  Sales  subject  to  reduction  for  Combination  Product. If  (a)  a  Licensed
Product  is  Covered  by  a  claim  of  any  patent(s)  or  patent  application(s)  owned,  licensed,  or  controlled  by  a  non-Affiliate  third  party  (other  than  The  Regents)  in  the
Territory, and Licensee, an Affiliate thereof, or any Sublicensee licenses such patent(s) or patent application(s); or (b) Licensee, an Affiliate thereof, or any Sublicensee
reasonably determines that it is necessary or advisable to obtain a license to any patent(s) or patent application(s) owned, licensed, or controlled by a non-Affiliate third
party (other than The Regents) in order to minimize, mitigate, or avoid the risk of infringement-related litigation with respect to the manufacture, use, Commercialization
or development of a Licensed Product in the Territory (“Third Party Royalty”), then Licensee shall be entitled to deduct * percent ( * %) of the consideration actually
paid  to  any  such  non-Affiliate  third  party  for  any  such  rights  in  a  particular  country  from  any  payments  due  to  The  Regents  under  Section  5.3  of  this Agreement,
provided that:

(i)

(ii)

Prior to giving effect to the reduction contemplated by this Paragraph 5.9, the sum of such Third Party Royalty rate and the Earned Royalty rate set forth in
Paragraph 5.1 is equal to, or greater than, * percent ( * %);

On an ongoing basis and prior to reduction of any Earned Royalty due The Regents under this Agreement for a given calendar quarter, Licensee first provides
written evidence to The Regents of Licensee’s royalty obligations to such non-Affiliate third party for such calendar quarter demonstrating that such royalty
obligation is in consideration for patent rights owned or controlled by such non-Affiliate third party without a license to which Licensee would infringe such
non-Affiliate third party patent rights in the manufacture, use, import, offer for sale, or sale of a Licensed Product; and

(iii)

Amounts payable will not be reduced, with respect to any calendar quarter, below * percent ( *%) of the amounts otherwise due to The Regents with respect to
such calendar quarter without such offset.

6.1

Upon  execution  of  this  Agreement,  Licensee  must  use  Commercially  Reasonable  Efforts  to  earnestly  and  diligently  (a)  develop  Licensed  Products  and  Licensed
Methods; (b) bring to market Licensed Products and Licensed Methods; and (c) manufacture and sell Licensed Products and Licensed Methods in quantities sufficient to
meet the market demands for them (all of the foregoing collectively “Commercialization”). For purposes of clarity, the requirements under the foregoing subsection (b)
and (c) shall continue to apply after a First Commercial Sale. The Regents agrees that the activities of Sublicensees and contractors with respect to Licensed Products
shall be deemed to be performance by Licensee of its diligence obligations.

6.2

The Regents has the right and option to either terminate this Agreement or reduce Licensee’s exclusive license to a nonexclusive license if Licensee fails to perform any
of the terms in Paragraph 6.1 or this Paragraph 6.2. This right, if exercised by The Regents, supersedes the rights granted in Article 2 (GRANT).

Commercialize any Licensed Product.

7.      PATENT FILING, PROSECUTION AND MAINTENANCE

Patent Prosecution
7.1a

Regents’ Patent Rights will be held in the name of The Regents and obtained with counsel of The Regents’ choice. The Regents shall control all Patent Actions
and all decisions with respect to Patent Actions and will reasonably consider any comments or suggestions by Licensee with respect to Patent Actions. The
Regents is entitled to take action to preserve rights and minimize costs whether or not Licensee has commented, and will use reasonable efforts to file, prosecute
and maintain Regents’ Patent Rights and to not allow any Regents’ Patent Rights for which Licensee is licensed and is underwriting the costs of to lapse or
become abandoned without Licensee’s written authorization under this Article 7, except for the filing of continuations, divisionals, or the like that substitute for
the  lapsed  application.  The  Regents  shall  have  no  requirement  to  file,  prosecute,  or  maintain  Regents’  Patent  Rights  if  Licensee  is  more  than  *  (  *  )  days
overdue to pay at least * dollars ($ * ) in invoiced Patent Cost obligations as set forth in this Article 7 and does not cure such breach.

7.1b

7.1c

The Regents will (a) furnish the Licensee with copies of all correspondence relating to the Regents’ Patent Rights from the United States Patent and Trademark
Office (USPTO) and any other patent office, as well as copies of all proposed responses to such correspondence in time for Licensee to review and comment on
such response; (b) give Licensee an opportunity to review the text of each patent application relating to Regents’ Patent Rights before filing; (c) consult with
Licensee with respect thereto; and (d) supply Licensee with a copy of the application as filed, together with notice of its filing date and serial number. The
Regents  shall  give  Licensee  the  opportunity  to  provide  comments  on  and  make  requests  of  The  Regents  concerning  the  preparation,  filing,  prosecution,
protection and maintenance of the Regents’ Patent Rights, and shall reasonably consider such comments and requests.

Licensee  has  the  right  to  request  Patent Actions  via  a  written  request  to  The  Regents  ninety  (90)  days  prior  to  the  deadline  set  by  the  patent  office  in  the
territory such Patent Action is to take place in (a “ Patent Prosecution Request”). The absence of a given Patent Prosecution Request by such deadline will be
considered an election not to secure the patent rights associated with the specific phase of patent prosecution in such territory (“Abandoned Patent Rights”),
and such Abandoned Patent Rights will not be part of Regents’ Patent Rights and therefore not subject to this Agreement, and Licensee will have no further
rights or license to them. The Regents will have the right to file patent applications at its own expense in any territory with respect to Abandoned Rights.

Past Patent Costs
Licensee will bear all Patent Costs incurred prior to the term of this Agreement of approximately * Dollars ($ * ) (“Past Patent Costs”). Licensee must send payment
for such Past Patent Costs to The Regents within thirty (30) days of Licensee’s receipt of an invoice for these costs.

Ongoing Patent Costs
Licensee  will  bear  all  Patent  Costs  incurred  during  the  term  of  this Agreement  (“Ongoing  Patent  Costs”)  and  shall  pay  in  advance  The  Regents’  patent  counsel’s
estimated  costs  for  undertaking  a  Patent Action,  which  estimates  The  Regents  will  share  with  Licensee,  before  The  Regents  authorizes  its  patent  counsel  to  proceed
(“Advanced Payment”). Fees and expenses that are due to incidentals (for example photocopy charges or long distance phone charges) are not included within such
estimate unless expressly so stated, nor is Licensee’s interaction with The Regents’ counsel such as by phone calls, e-mails, and in person meetings. The absence of this
Advanced  Payment  will  be  considered  an  election  not  to  secure  the  patent  rights  associated  with  the  specific  phase  of  patent  prosecution  in  such  territory,  and  such
patent application(s) and patent(s) will not be part of Regents’ Patent Rights and therefore not subject to this Agreement, and Licensee will have no further rights or
license to them.

Termination of Patent Prosecution by Licensee
7.4a

Licensee may terminate its obligations with respect to any or all of Regents’ Patent Rights by providing written notice to The Regents (“Patent Termination
Notice”). Termination of Licensee’s obligations with respect to such patent application or patent will be effective three (3) months after receipt of such Patent
Termination  Notice  by  The  Regents.  The  Regents  will  use  reasonable  efforts  to  curtail  Patent  Costs  chargeable  to  Licensee  under  this Agreement  after  this
Patent Termination Notice is received by The Regents. The Regents may continue prosecution or maintenance of these application(s) or patent(s) at its sole
discretion  and  expense,  and  such  application(s)  and  patent(s)  will  not  be  part  of  Regents’  Patent  Rights  and  therefore  not  subject  to  this Agreement,  and
Licensee will have no rights or license to them.

Patent Extensions
7.5a

Licensee will apply for an extension of the term of any patent included within The Regents’ Patent Rights, if appropriate in Licensee’s reasonable discretion
after discussion with The Regents, under the Drug Price Competition and Patent Term Restoration Act of 1984 and/or European, Japanese and other foreign
counterparts. Licensee shall prepare all documents, and The Regents agrees to execute the documents and to take additional action as Licensee reasonably
requests in connection therewith. Licensee will be liable for all documented out-of-pocket costs relating to such application.

7.5b

If  either  party  (in  the  case  of  The  Regents,  the  licensing  officer  responsible  for  administration  of  this  Agreement)  receives  notice  pertaining  to  the
infringement  or  potential  infringement  of  any  issued  patent  included  with  Regents’  Patent  Rights  under  the  Drug  Price  Competition  and  Patent  Term
Restoration Act of 1984 (and/or foreign counterparts of this law) then that party shall within ten (10) days notify the other party after receipt of such notice of
infringement.

8.      PATENT INFRINGEMENT

In the event that The Regents (to the extent of the actual knowledge of the licensing professional responsible for the administration of this Agreement) or Licensee learns
of infringement of any Regents’ Patent Rights licensed under this Agreement, the knowledgeable party will provide the other with (i) written notice of such infringement
and (ii) evidence of such infringement available to it (the “Infringement Notice”). During the period in which, and in the jurisdiction where, Licensee has exclusive
rights under this Agreement, except as set forth below, neither The Regents nor Licensee will notify a third party (including the infringer) of infringement or put such
third party on  notice  of  the  existence  of  any  Regents’  Patent  Rights  without  first  meeting,  either  in-person  or  by  teleconference,  within  fifteen  (15)  business  days  of
receipt  of  the  respective  Infringement  Notice  to  discuss  a  reasonable  plan  of  action  (the  “Infringement Meeting”).  Notwithstanding  the  foregoing,  in  the  event  the
Infringement  Meeting  does  not  occur  within  fifteen  (15)  business  days  following  the  date  of  receipt  of  the  respective  Infringement  Notice,  (a)  Licensee  shall  be
permitted to notify third parties (including the infringer) of such infringement and/or put such third party on notice of the existence of any Regents’ Patent Rights, and (b)
if Licensee provides any such notice to a third party within thirty (30) days following the date of the respective Infringement Notice, Licensee shall notify The Regents of
the same at or prior to the time Licensee provides such notice to a third party. If, before the earlier of the Infringement Meeting or the expiration of the above-mentioned
fifteen (15) business day period, Licensee puts such infringer on notice of the existence of any Regents’ Patent Rights with respect to such infringement without first
obtaining the written consent of The Regents and if a declaratory judgment action is filed by such infringer against The Regents, then Licensee’s right to initiate a suit
against such infringer for infringement under Paragraph 8.2 below will terminate immediately without the obligation of The Regents to provide notice to Licensee. Both
The Regents and Licensee will use their diligent efforts to cooperate with each other to terminate such infringement without litigation.

Licensee shall have the exclusive, first and primary right, but not the obligation, to institute suit, prosecute and control any action or proceeding with respect to such
infringement  against  the  infringer,  provided  that  (i)  Licensee  shall  not  institute  a  suit  against  the  infringer  with  respect  to  such  infringement  prior  to  the  respective
Infringement Meeting unless such Infringement Meeting does not occur within fifteen (15) business days following the date of the respective Infringement Notice, and
(ii)  Licensee  shall  provide  ten  (10)  days’  prior  written  notice  to  The  Regents  if  it  is  going  to  institute  such  a  suit  within  thirty  (30)  days  following  the  date  of  the
respective Infringement Notice. Subject to Article 8.6, Licensee shall be free to enter into a settlement, consent judgment, or other voluntary disposition with respect to
any such action. The Regents may voluntarily join such suit at its own expense, but may not thereafter commence suit against the infringer for the acts of infringement
that are the subject of Licensee’s suit or any judgment rendered in the suit. Licensee may not join The Regents in a suit initiated by Licensee without The Regents’ prior
written consent, such consent subject to the approval of the UC Board of Regents. The Regents will support any such request made to the UC Board of Regents, and will
make best efforts to ensure a prompt response to such request.. If The Regents is joined in any litigation instituted by Licensee, then Licensee will pay any documented
costs incurred by The Regents arising out of such suit, including but not limited to, any legal fees of counsel that The Regents selects and retains to represent it in the
suit.

If, within one eighty (180) days following the date the Infringement Notice is received, infringing activity of potential commercial significance by the infringer has not
been abated and if Licensee has not brought suit against the infringer or taken other legal action to abate such infringement, then The Regents may institute suit for
patent infringement against the infringer. If The Regents institutes such suit, then Licensee may not join such suit without The Regents’ consent and may not thereafter
commence  suit  against  the  infringer  for  acts  of  infringement  that  are  subject  to  The  Regents’  suit  or  any  judgment  rendered  in  that  suit.  The  Regents  shall  not  join
Licensee in a suit initiated by The Regents’ without Licensee’s prior written consent.

Any recovery or settlement received in connection with any suit will first be shared by The Regents and Licensee equally to cover any litigation costs each incurred and
next shall be paid to The Regents or Licensee to cover any litigation costs it incurred in excess of the litigation costs of the other. In any suit initiated by Licensee, any
recovery in excess of litigation costs will be shared between Licensee and The Regents as follows:

The Regents will receive * percent ( * %) of the recovery, except for any portion of the recovery or settlement attributable and paid as enhanced damages for willful
infringement, for which The Regents will receive * percent ( * %) of the recovery.

In any suit initiated by The Regents in conformity with the provisions of this Article 8, any recovery in excess of litigation costs will belong to The Regents. The Regents
and Licensee agree to be bound by all final and non-appealable determinations of patent infringement, validity and enforceability (but no other issue) resolved by any
adjudicated judgment in a suit brought in compliance with this Article 8 (PATENT INFRINGEMENT).

Licensee’s rights under this Article 8 may be exercised by its Sublicensees to the extent provided in the applicable Sublicense Agreement.

Any agreement made by Licensee for purposes of settling litigation or other dispute shall comply with the requirements of Article 3 (SUBLICENSES) of this Agreement.
No settlement, consent judgment or other voluntary disposition of any action described in this Article 8 shall (i) materially limit the scope, validity, or enforceability of
patents included in the Regents’ Patent Rights or (ii) admit fault or wrongdoing on the part of The Regents or Licensee, without the prior written approval of the Regents
and Licensee, which, such approval not to be unreasonably withheld.

Each party will cooperate with the other in litigation proceedings instituted hereunder but at the expense of the party who initiated the suit (unless such suit is being
jointly prosecuted by the parties).

Any litigation proceedings will be controlled by the party bringing the suit, except that The Regents may be represented by counsel of its choice in any suit brought by
Licensee.

If Licensee violates or fails to perform any material term of this Agreement, then The Regents may give written notice of the default (“Notice of Default”) to Licensee.
If Licensee does not repair such default within sixty (60) days after receipt by Licensee of the Notice of Default (“Period to Cure”), then The Regents has the right to
terminate this Agreement and the License by a second written notice (“Notice of Termination”) to Licensee. If The Regents sends a Notice of Termination to Licensee,
then this Agreement automatically terminates on the effective date of this notice. Termination does not relieve Licensee of its obligation to pay any monies owed at the
time of the Termination Effective Date, and does not impair any accrued right of The Regents.

13.      TERMINATION BY LICENSEE

Licensee has the right at any time to terminate this Agreement in whole or with respect to any portion of Regents’ Patent Rights by giving written notice to The Regents.
This notice of termination will be subject to Article 20 (NOTICES) and will be effective thirty (30) days after the effective date of the notice (“Termination Effective
Date”).

Any termination in accordance with Paragraph 13.1 does not relieve Licensee of any obligation or liability accrued prior to termination. Nor does termination rescind
anything done by Licensee or any payments made to The Regents prior to the effective date of termination. Termination does not affect in any manner any rights of The
Regents arising under this Agreement prior to termination.

in the form and at the times specified in this Agreement, Licensee may continue to sell all previously made Licensed Products during the one hundred eighty (180) days
following the effective date of the Notice of Termination. Licensee will not have this right if this Agreement is terminated for any other causes.

Licensee  must  submit  royalty  reports  on  the  sale  of  Licensed  Products  allowed  under  this Article  14  in  accordance  with Article  9  (PROGRESS AND  ROYALTY
REPORTS) and must pay royalties on such sales at the same rate and at the same time provided in this Agreement for royalties on sales of Licensed Products made

18.      INDEMNIFICATION

18.1

To the maximum extent permitted by law, Licensee will, and will require its Sublicensees to, indemnify, hold harmless and defend The Regents, The Regents’ officers,
employees, and agents, the sponsors of the research that led to the Invention, the inventors of the patents and patent applications in Regents’ Patent Rights and their
respective employers (the “Indemnitees”)from and against any and all liability, claims, suits, losses, damages, costs, fees and expenses resulting from or arising out of
exercise of this license or any Sublicense; provided, however, that Licensee and Sublicensees will have no obligations under this Paragraph 18.1 with respect to claims,
demands or actions arising out of an Indemnitee’s gross negligence, intentional misconduct or breach of this Agreement. Indemnification includes but is not limited to
products liability. If The Regents, in its sole discretion, believes that there will be a conflict of interest or it will not otherwise be adequately represented by counsel
chosen by Licensee to defend The Regents in accordance with this Paragraph 18.1, then The Regents may retain counsel of its choice to represent it, and Licensee will
pay all documented expenses for such representation. Licensee’s agreement to indemnify, defend, and hold harmless under this Section 18.1 is conditioned upon the
Indemnitee (a) providing written notice to Licensee of any claim, demand or action arising out of the indemnified matter as soon as reasonably possible; (b) permitting
Licensee (or Sublicensee, as the case may be) to assume control over the investigation of, preparation and defense against, and settlement or voluntary disposition of any
such  claim,  demand  or  action;  (c)  assisting  the  Licensee  (or  Sublicensee,  as  the  case  may  be),  in  the  investigation,  preparation,  defense,  and  settlement  or  voluntary

Regents if the assignment of this Agreement is to: (a) an Affiliate of Licensee; or (b) in conjunction with the transfer to a non-Affiliate third party of all or substantially
all of the business or assets of Licensee to which this license relates.

Conditions of Assignment
No later than thirty (30) days following the effective date of any assignment of this Agreement all of the following terms and conditions shall be met and if they are not

including, without limitation, those related to the manufacture, use, labeling importation and marketing of Licensed Products and Licensed Services; and

(c)          without limiting the foregoing and notwithstanding any other provision in this Agreement, Licensee acknowledges and agrees that it is an exclusive
Licensee under this Agreement and agrees (i) to be subject to all laws and other obligations applicable to the CIRM Grant as they apply to an exclusive Licensee, including
diligence, reporting, access and pricing requirements, and (ii) to assist COH as necessary to ensure COH remains in compliance with any laws and other obligations applicable
to the CIRM Grant.

ARTICLE 7: INTELLECTUAL PROPERTY; PATENT PROSECUTION, MAINTENANCE AND ENFORCEMENT.

7.1           Patent Prosecution, Maintenance and Enforcement.

(a)          COH shall be responsible for the preparation, filing, prosecution, and maintenance of all Patent Rights, using counsel of its choice. COH will timely
provide Licensee with copies of all relevant documentation relating to such prosecution and Licensee shall keep such information confidential. In addition, COH shall instruct
the patent counsel prosecuting Patent Rights to (i) copy Licensee on patent prosecution documents that are received from or filed with the United States Patent and Trademark
Office  and  foreign  equivalent,  as  applicable;  (ii)  if  requested  by  Licensee,  provide  Licensee  with  copies  of  draft  submissions  to  the  USPTO  prior  to  filing;  and  (iii)  give
reasonable consideration to the comments and requests of Licensee or its patent counsel, provided that (a) COH reserves the sole right to make all final decisions with respect to
the preparation, filing, prosecution and maintenance of such patent applications and patents; and (b) the patent counsel remains counsel to COH (and shall not jointly represent
Licensee unless requested by Licensee and approved by COH, and an appropriate engagement letter and conflict waiver are in effect). All patents and patent applications in
Patent Rights, to the extent assignable in whole or in part to COH, shall be assigned to COH.

(b)          COH will not unreasonably refuse to amend any patent application in Patent Rights to include claims reasonably requested by Licensee to protect the
products contemplated to be sold by Licensee under this Agreement. If Licensee informs COH of other countries or jurisdictions in which it wishes to obtain patent protection
with  respect  to  the  Patent  Rights,  COH  shall  prepare,  file,  prosecute  and  maintain  patent  applications  in  such  countries  and  any  patents  resulting  therefrom  (and,  for  the
avoidance of doubt, such patent applications and patents shall be deemed included in the Patent Rights). On a country by country and patent by patent basis, Licensee may elect
to surrender any patent or patent application in Patent Rights in any country upon sixty (60) days advance written notice to COH. Such notice shall relieve Licensee from the
obligation to pay for future patent costs but shall not relieve Licensee from responsibility to pay patent costs incurred prior to the expiration of the sixty (60) day notice period.
Such U.S. or foreign patent application or patent shall thereupon cease to be a Patent Right hereunder, Licensee shall have no further rights therein and COH shall be free to
license its rights to that particular U.S. or foreign patent application or patent to any other party on any terms.

(c)          Each Party shall promptly provide written notice to the other in the event it becomes aware of any actual or probable infringement of any of the
Patent Rights in or relevant to the Field or of any Third Party claim regarding the enforceability or validity of any Patent Rights (“Infringement Notice”). Licensee shall, in
cooperation with COH, use reasonable efforts to terminate infringement without litigation.

(d)                    If  infringing  activity  has  not  been  abated  within  ninety  (90)  days  following  the  date  the  Infringement  Notice  takes  effect,  then  Licensee  may,
following consultation with COH, in its sole discretion and at its sole expense, take action against any alleged infringer or in defense of such any claim, provided, that Licensee
has exclusive rights under this Agreement. Any recovery obtained by Licensee as the result of legal proceedings initiated and paid for by Licensee pursuant to this subsection
(d), after deduction of Licensee’s reasonable out-of-pocket expenses incurred in securing such recovery, shall be deemed to be Licensee Net Sales or Sublicensee Net Sales, as
applicable,  of  Licensed  Products  and/or  Licensed  Services  in  the  calendar  quarter  in  which  such  recovery  was  received  and  royalties  shall  be  due  and  payable  thereon
accordingly.

(f)          In the event that Licensee declines either to cause such infringement to cease (e.g., by settlement or injunction) or to initiate and thereafter diligently
maintain  legal  proceedings  against  the  infringer  other  than  as  part  of  a  mutually  agreed  upon  bona  fide  strategy,  developed  with  the  guidance  of  outside  patent  counsel,  to
preserve the Patent Rights, COH may, in its sole discretion and at its sole expense, take action against such alleged infringer or in defense of any such Third Party claim. Any
recovery obtained by COH as the result of any such legal proceedings shall be for the benefit of COH only.

7 . 2           Trademarks. Licensee shall be responsible for the selection, registration, maintenance, and defense of all trademarks for use in connection with the sale or
marketing  of  Licensed  Products  and  Licensed  Services  in  the  Field  in  the  Territory  (the  “ Marks”),  as  well  as  all  expenses  associated  therewith. All  uses  of  the  Marks  by
Licensee or a Sublicensee shall comply in all material respects with all applicable laws and regulations (including those laws and regulations particularly applying to the proper
use and designation of trademarks in the applicable countries). Licensee shall not, without COH’s prior written consent, use any trademarks or house marks of COH (including
the  COH  corporate  name),  or  marks  confusingly  similar  thereto,  in  connection  with  Licensee  commercialization  of  Licensed  Products  or  Licensed  Services  under  this
Agreement  in  any  promotional  materials  or  applications  or  in  any  manner  implying  an  endorsement  by  COH  of  Licensee  or  the  Licensed  Products  or  Licensed  Services.

any challenge in a legal or administrative proceeding to the patentability, validity or enforceability of any of the Patent Rights (or any claim thereof), including by: (a) filing or
pursuing a declaratory judgment action in which any of the Patent Rights is alleged to be invalid or unenforceable; (b) citing prior art against any of the Patent Rights, filing a
request for or pursuing a re-examination of any of the Patent Rights (other than with COH’s written agreement), or becoming a party to or pursuing an interference; or (c) filing
or pursuing any re-examination, opposition, cancellation, nullity or other like proceedings against any of the Patent Rights; but excluding any challenge raised as a defense
against a claim, action or proceeding asserted by COH against Licensee, its Affiliates or Sublicensees. In lieu of exercising its rights to terminate under this Section 7.3 COH
may  elect  upon  written  notice  to  increase  the  payments  due  under  all  of  Article  4  by  *  percent  (*%),  which  election  will  be  effective  retroactively  to  the  date  of  the
commencement of the Patent Challenge. Licensee acknowledges and agrees that this Section 7.3 is reasonable, valid and necessary for the adequate protection of COH’s interest
in and to the Patent Rights, and that would not have granted to Licensee the licenses under those Patent Rights, without this Section 7.3.

7.4           Payment of COH Patent Expenses.

(a)          The Parties acknowledge that, prior to the Effective Date, COH provided to Licensee documentation of historic expenses incurred by COH with
respect  to  the  drafting,  prosecution  and  maintenance  of  the  Patent  Rights.  In  consideration  of  such  historic  expenditures  by  COH,  Licensee  shall  reimburse  COH  for  such
expenses within 30 days after the Effective Date.

(b)          After the Effective Date, COH shall provide to Licensee an annual invoice and reasonably detailed documentation with respect to COH’s out-of-
pocket expenses incurred with respect to such prosecution and maintenance for the previous year. Licensee shall reimburse COH for * percent of such expenses within 30 days
after receipt of such invoice and documentation.

7 . 5           Marking. Licensee and its Sublicensees shall mark all Licensed Products and all materials related to Licensed Services in such a matter as to conform with

the patent laws of the country to which such Licensed Products are shipped or in which such products are sold and such Licensed Services performed.

ARTICLE 8: TERM AND TERMINATION

8 . 1           Term and Expiration of Term . The term of this Agreement (the “Term”) shall commence on the Effective Date and, notwithstanding any other provision

10.2         Indemnification by COH. COH shall defend, indemnify and hold harmless Licensee and its Affiliates and their respective officers, directors, shareholders,
employees  and  agents  (collectively,  the  “ Licensee Indemnitees”)  from  and  against  any  and  all  Losses  caused  directly  by:  (i)  the  material  breach  of  any  representation  or
warranty made by COH under this Agreement, or (ii) the gross negligence or willful misconduct of a COH Indemnitee, except to the extent that such Losses arise out of or are
in  any  way  attributable  to:  (a)  the  material  breach  of  any  representation  or  warranty  made  by  Licensee  under  this Agreement,  (b)  the  research,  development,  marketing,
approval, manufacture, packaging, labeling, handling, storage, transportation, use, distribution, promotion, marketing or sale of Licensed Products or Licensed Services by or on
behalf of Licensee or a Sublicensee, or (c) the negligence, willful misconduct or failure to comply with applicable law by a Licensee Indemnitee or a Sublicensee.

1 0 . 3         Procedure.  The  indemnities  set  forth  in  this Article  10  are  subject  to  the  condition  that  the  Party  seeking  the  indemnity  shall  forthwith  notify  the
indemnifying Party on being notified or otherwise made aware of a liability, claim, suit, action or expense and that the indemnifying Party defend and control any proceedings
with the other Party being permitted to participate at its own expense (unless there shall be a conflict of interest which would prevent representation by joint counsel, in which
event  the  indemnifying  Party  shall  pay  for  the  other  Party’s  counsel);  provided, that,  the  indemnifying  Party  may  not  settle  the  liability,  claim,  suit,  action  or  expense,  or
otherwise  admit  fault  of  the  other  Party  or  consent  to  any  judgment,  without  the  written  consent  of  the  other  Party  (such  consent  not  to  be  unreasonably  withheld).
Notwithstanding the foregoing, no delay in the notification of the existence of any claim of Loss shall cause a failure to comply with this Section 10.3 as long as such delay shall
not have materially impaired the rights of the indemnifying Party.

10.4         Insurance.

(a)                    Within  30  days  following  the  Effective  Date,  Licensee  shall  procure  at  its  sole  expense  and  provide  to  COH  evidence  of  comprehensive  or

personal and advertising injury, $*; and general aggregate (commercial form only), $*.

(b)          The foregoing policies will provide primary coverage to COH and shall name the COH Indemnitees as additional insureds, and shall remain in effect
during the term of this Agreement and for * years following the termination or expiration of the term of this Agreement. The COH Indemnitees shall be notified in writing by
Licensee not less than 30 days prior to any modification, cancellation or non-renewal of such policy. Licensee’s insurance must include a provision that the coverages will be
primary and will not participate with nor will be excess over any valid and collective insurance or program of self-insurance carried or maintained by the COH Indemnitees.
Such insurance coverage shall be maintained with an insurance company or companies having an A.M. Best’s rating (or its equivalent) of A-XII or better.

(c)          Licensee expressly understands that the coverage limits in Section 10.4(a) do not in any way limit the Licensee’s liability.

to be paid to any taxing authority with respect to such payments. Licensee shall provide to COH all relevant documents and correspondence, and shall also provide to COH any
other cooperation or assistance on a reasonable basis as may be necessary to enable COH to claim exemption from such withholding taxes and to receive a full refund of such

Licensed Product is sold or Licensed Service provided, payment shall be made through such lawful means or methods as Licensee may determine. When in any country, the law
or regulations prohibit both the transmittal and deposit of royalties or other payments, Licensee shall continue to report all such amounts, but may suspend payment for as long

prohibition, together with accrued interested thereon, shall promptly be transmitted to COH.

5.3           Accounts and Audit.

5.3.1           Records. Licensee shall keep, and shall require that each Sublicensee keep, full, true and accurate books of account containing the particulars of

its Sublicensees.

5.3.3           Procedures for Audit. COH may exercise its right to have Licensee’s and its Sublicensees’ relevant records examined only during the five year
period during which Licensee is required to maintain records, no more than once in any consecutive four calendar quarters. Licensee and its Sublicensees are required to make

such periods, then COH shall provide to Licensee a credit against future payments (such credit equal to the full amount of that overpayment), or, if Licensee is not obligated to
make any future payments, then COH shall pay to Licensee the full amount of that overpayment. Contested amounts are subject to dispute resolution under Article 12. If the

ARTICLE 7: INTELLECTUAL PROPERTY; PATENT PROSECUTION, MAINTENANCE AND ENFORCEMENT.

7.1           Patent Prosecution, Maintenance and Enforcement.

(a)          COH shall be responsible for the preparation, filing, prosecution, and maintenance of all CD123 Patent Rights, using counsel of its choice. COH will
timely provide Licensee with copies of all relevant documentation relating to such prosecution and Licensee shall keep such information confidential. In addition, COH shall
instruct the patent counsel prosecuting CD123 Patent Rights to (i) copy Licensee on patent prosecution documents that are received from or filed with the United States Patent
and Trademark Office and foreign equivalent, as applicable; (ii) if requested by Licensee, provide Licensee with copies of draft submissions to the USPTO prior to filing; and
(iii) give reasonable consideration to the comments and requests of Licensee or its patent counsel, provided that (a) COH reserves the sole right to make all final decisions with
respect to the preparation, filing, prosecution and maintenance of such patent applications and patents; and (b) the patent counsel remains counsel to COH (and shall not jointly
represent  Licensee  unless  requested  by  Licensee  and  approved  by  COH,  and  an  appropriate  engagement  letter  and  conflict  waiver  are  in  effect).  All  patents  and  patent
applications in CD123 Patent Rights, to the extent assignable in whole or in part to COH, shall be assigned to COH.

(b)          COH will not unreasonably refuse to amend any patent application in CD123 Patent Rights to include claims reasonably requested by Licensee to
protect the products contemplated to be sold by Licensee under this Agreement. If Licensee informs COH of other countries or jurisdictions in which it wishes to obtain patent
protection with respect to the CD123 Patent Rights, COH shall prepare, file, prosecute and maintain patent applications in such counties and any patents resulting therefrom
(and, for the avoidance of doubt, such patent applications and patents shall be deemed included in the CD123 Patent Rights). On a country by country and patent by patent basis,
Licensee may elect to surrender any patent or patent application in CD123 Patent Rights in any country upon sixty (60) days advance written notice to COH. Such notice shall
relieve Licensee from the obligation to pay for future patent costs but shall not relieve Licensee from responsibility to pay patent costs incurred prior to the expiration of the
sixty (60) day notice period. Such U.S. or foreign patent application or patent shall thereupon cease to be a CD123 Patent Right hereunder, Licensee shall have no further rights
therein and COH shall be free to license its rights to that particular U.S. or foreign patent application or patent to any other party on any terms.

(c)          Each Party shall promptly provide written notice to the other in the event it becomes aware of any actual or probable infringement of any of the
CD123  Patent  Rights  in  or  relevant  to  the  Field  or  of  any  Third  Party  claim  regarding  the  enforceability  or  validity  of  any  CD123  Patent  Rights  (“Infringement  Notice”).
Licensee shall, in cooperation with COH, use reasonable efforts to terminate infringement without litigation.

(d)                    If  infringing  activity  has  not  been  abated  within  ninety  (90)  days  following  the  date  the  Infringement  Notice  takes  effect,  then  Licensee  may,
following consultation with COH, in its sole discretion and at its sole expense, take action against any alleged infringer or in defense of such any claim, provided, that Licensee
has exclusive rights under this Agreement. Any recovery obtained by Licensee as the result of legal proceedings initiated and paid for by Licensee pursuant to this subsection
(d), after deduction of Licensee’s reasonable out-of-pocket expenses incurred in securing such recovery, shall be deemed to be Net Sales of Licensed Products and/or Licensed
Services in the calendar quarter in which such recovery was received and royalties shall be due and payable thereon accordingly.

(f)          In the event that Licensee declines either to cause such infringement to cease (e.g., by settlement or injunction) or to initiate and thereafter diligently
maintain  legal  proceedings  against  the  infringer  other  than  as  part  of  a  mutually  agreed  upon  bona  fide  strategy,  developed  with  the  guidance  of  outside  patent  counsel,  to
preserve the CD123 Patent Rights, COH may, in its sole discretion and at its sole expense, take action against such alleged infringer or in defense of any such Third Party claim.
Any recovery obtained by COH as the result of any such legal proceedings shall be for the benefit of COH only.

7 . 2           Trademarks. Licensee shall be responsible for the selection, registration, maintenance, and defense of all trademarks for use in connection with the sale or
marketing  of  Licensed  Products  and  Licensed  Services  in  the  Field  in  the  Territory  (the  “ Marks”),  as  well  as  all  expenses  associated  therewith. All  uses  of  the  Marks  by
Licensee or a Sublicensee shall comply in all material respects with all applicable laws and regulations (including those laws and regulations particularly applying to the proper
use and designation of trademarks in the applicable countries). Licensee shall not, without COH’s prior written consent, use any trademarks or house marks of COH (including
the  COH  corporate  name),  or  marks  confusingly  similar  thereto,  in  connection  with  Licensee  commercialization  of  Licensed  Products  or  Licensed  Services  under  this
Agreement  in  any  promotional  materials  or  applications  or  in  any  manner  implying  an  endorsement  by  COH  of  Licensee  or  the  Licensed  Products  or  Licensed  Services.
Licensee shall own all Marks.

7.3           Challenge to the CD123 Patent Rights by Licensee.

(a)          COH may terminate this Agreement and, notwithstanding Section 3.3, above, all Sublicenses issued hereunder, upon written notice to Licensee in the
event that Licensee or any of its Affiliates or Sublicensees directly or indirectly asserts a Patent Challenge. “Patent Challenge” means any challenge in a legal or administrative
proceeding to the patentability, validity or enforceability of any of the CD123 Patent Rights (or any claim thereof), including by: (a) filing or pursuing a declaratory judgment
action in which any of the CD123 Patent Rights is alleged to be invalid or unenforceable; (b) citing prior art against any of the CD123 Patent Rights, filing a request for or
pursuing a re-examination of any of the CD123 Patent Rights (other than with COH’s written agreement), or becoming a party to or pursuing an interference; or (c) filing or
pursuing any re-examination, opposition, cancellation, nullity or other like proceedings against any of the CD123 Patent Rights; but excluding any challenge raised as a defense
against a claim, action or proceeding asserted by COH against Licensee, its Affiliates or Sublicensees. In lieu of exercising its rights to terminate under this Section 7.3(a) COH
may  elect  upon  written  notice  to  increase  the  payments  due  under  all  of  Section  4  by  *  percent  (*%),  which  election  will  be  effective  retroactively  to  the  date  of  the
commencement of the Patent Challenge. Licensee acknowledges and agrees that this Section 7.3(a) is reasonable, valid and necessary for the adequate protection of COH’s
interest in and to the CD123 Patent Rights, and that would not have granted to Licensee the licenses under those CD123 Patent Rights, without this Section 7.3(a).

(c)          After the Original Effective Date, COH shall provide to Licensee an annual invoice and reasonably detailed documentation with respect to COH’s

this Agreement between the Parties with respect to the payment of milestones or royalties with respect to Licensed Products and Licensed Services have been satisfied (such
expiry of the Term hereinafter referred to as “Expiration”).

ARTICLE 7: INTELLECTUAL PROPERTY; PATENT PROSECUTION, MAINTENANCE AND ENFORCEMENT.

7.1           Patent Prosecution, Maintenance and Enforcement.

(a)          COH shall be responsible for the preparation, filing, prosecution, and maintenance of all IL-13 Patent Rights, using counsel of its choice. COH will
timely provide Licensee with copies of all relevant documentation relating to such prosecution and Licensee shall keep such information confidential. In addition, COH shall
instruct the patent counsel prosecuting IL-13 Patent Rights to (i) copy Licensee on patent prosecution documents that are received from or filed with the United States Patent
and Trademark Office and foreign equivalent, as applicable; (ii) if requested by Licensee, provide Licensee with copies of draft submissions to the USPTO prior to filing; and
(iii) give reasonable consideration to the comments and requests of Licensee or its patent counsel, provided that (a) COH reserves the sole right to make all final decisions with
respect to the preparation, filing, prosecution and maintenance of such patent applications and patents; and (b) the patent counsel remains counsel to COH (and shall not jointly
represent  Licensee  unless  requested  by  Licensee  and  approved  by  COH,  and  an  appropriate  engagement  letter  and  conflict  waiver  are  in  effect).  All  patents  and  patent
applications in IL-13 Patent Rights, to the extent assignable in whole or in part to COH, shall be assigned to COH.

(b)          COH will not unreasonably refuse to amend any patent application in IL-13 Patent Rights to include claims reasonably requested by Licensee to
protect the products contemplated to be sold by Licensee under this Agreement. If Licensee informs COH of other countries or jurisdictions in which it wishes to obtain patent
protection with respect to the IL-13 Patent Rights, COH shall prepare, file, prosecute and maintain patent applications in such counties and any patents resulting therefrom (and,
for  the  avoidance  of  doubt,  such  patent  applications  and  patents  shall  be  deemed  included  in  the  IL-13  Patent  Rights).  On  a  country  by  country  and  patent  by  patent  basis,
Licensee may elect to surrender any patent or patent application in IL-13 Patent Rights in any country upon sixty (60) days advance written notice to COH. Such notice shall
relieve Licensee from the obligation to pay for future patent costs but shall not relieve Licensee from responsibility to pay patent costs incurred prior to the expiration of the
sixty (60) day notice period. Such U.S. or foreign patent application or patent shall thereupon cease to be a IL-13 Patent Right hereunder, Licensee shall have no further rights
therein and COH shall be free to license its rights to that particular U.S. or foreign patent application or patent to any other party on any terms.

(c)          Each Party shall promptly provide written notice to the other in the event it becomes aware of any actual or probable infringement of any of the IL-
13 Patent Rights in or relevant to the Field or of any Third Party claim regarding the enforceability or validity of any IL-13 Patent Rights (“Infringement Notice”). Licensee
shall, in cooperation with COH, use reasonable efforts to terminate infringement without litigation.

(d)                    If  infringing  activity  has  not  been  abated  within  ninety  (90)  days  following  the  date  the  Infringement  Notice  takes  effect,  then  Licensee  may,
following consultation with COH, in its sole discretion and at its sole expense, take action against any alleged infringer or in defense of such any claim, provided, that Licensee
has exclusive rights under this Agreement. Any recovery obtained by Licensee as the result of legal proceedings initiated and paid for by Licensee pursuant to this subsection
(d), after deduction of Licensee’s reasonable out-of-pocket expenses incurred in securing such recovery, shall be deemed to be Net Sales of Licensed Products and/or Licensed
Services in the calendar quarter in which such recovery was received and royalties shall be due and payable thereon accordingly.

including but not limited to, reasonable legal fees of counsel that COH selects and retains to represent it in the suit.

(e)                    If  COH  is  involuntarily  joined  in  a  suit  initiated  by  Licensee,  then  the  Licensee  will  pay  any  costs  incurred  by  COH  arising  out  of  such  suit,

(f)          In the event that Licensee declines either to cause such infringement to cease (e.g., by settlement or injunction) or to initiate and thereafter diligently
maintain  legal  proceedings  against  the  infringer  other  than  as  part  of  a  mutually  agreed  upon  bona  fide  strategy,  developed  with  the  guidance  of  outside  patent  counsel,  to
preserve the IL-13 Patent Rights, COH may, in its sole discretion and at its sole expense, take action against such alleged infringer or in defense of any such Third Party claim.
Any recovery obtained by COH as the result of any such legal proceedings shall be for the benefit of COH only.

7 . 2           Trademarks. Licensee shall be responsible for the selection, registration, maintenance, and defense of all trademarks for use in connection with the sale or
marketing  of  Licensed  Products  and  Licensed  Services  in  the  Field  in  the  Territory  (the  “ Marks”),  as  well  as  all  expenses  associated  therewith. All  uses  of  the  Marks  by
Licensee or a Sublicensee shall comply in all material respects with all applicable laws and regulations (including those laws and regulations particularly applying to the proper
use and designation of trademarks in the applicable countries). Licensee shall not, without COH’s prior written consent, use any trademarks or house marks of COH (including
the  COH  corporate  name),  or  marks  confusingly  similar  thereto,  in  connection  with  Licensee  commercialization  of  Licensed  Products  or  Licensed  Services  under  this
Agreement  in  any  promotional  materials  or  applications  or  in  any  manner  implying  an  endorsement  by  COH  of  Licensee  or  the  Licensed  Products  or  Licensed  Services.
Licensee shall own all Marks.

7.3           Challenge to the IL-13 Patent Rights by Licensee.

(a)          COH may terminate this Agreement and, notwithstanding Section 3.3, above, all Sublicenses issued hereunder, upon written notice to Licensee in the
event that Licensee or any of its Affiliates or Sublicensees directly or indirectly asserts a Patent Challenge. “Patent Challenge” means any challenge in a legal or administrative
proceeding to the patentability, validity or enforceability of any of the IL-13 Patent Rights (or any claim thereof), including by: (a) filing or pursuing a declaratory judgment
action in which any of the IL-13 Patent Rights is alleged to be invalid or unenforceable; (b) citing prior art against any of the IL-13 Patent Rights, filing a request for or pursuing
a re-examination of any of the IL-13 Patent Rights (other than with COH’s written agreement), or becoming a party to or pursuing an interference; or (c) filing or pursuing any
re-examination,  opposition,  cancellation,  nullity  or  other  like  proceedings  against  any  of  the  IL-13  Patent  Rights;  but  excluding  any  challenge  raised  as  a  defense  against  a
claim, action or proceeding asserted by COH against Licensee, its Affiliates or Sublicensees. In lieu of exercising its rights to terminate under this Section 7.3(a) COH may
elect upon written notice to increase the payments due under all of Section 4 by * percent (*%), which election will be effective retroactively to the date of the commencement
of the Patent Challenge. Licensee acknowledges and agrees that this Section 7.3(a) is reasonable, valid and necessary for the adequate protection of COH’s interest in and to the
IL-13 Patent Rights, and that would not have granted to Licensee the licenses under those IL-13 Patent Rights, without this Section 7.3(a).

COH, the Parties acknowledge and agree that Licensee has reimbursed COH for such expenses within thirty (30) days of the Original Effective Date.

(c)          After the Original Effective Date, COH shall provide to Licensee an annual invoice and reasonably detailed documentation with respect to COH’s
out-of-pocket expenses incurred with respect to such prosecution and maintenance for the previous year. Licensee shall reimburse COH for *  percent of such expenses within
thirty (30) days after receipt of such invoice and documentation.

7 . 4           Marking. Licensee and its Sublicensees shall mark all Licensed Products and all materials related to Licensed Services in such a matter as to conform with

the patent laws of the country to which such Licensed Products are shipped or in which such products are sold and such Licensed Services performed.

ARTICLE 8: TERM AND TERMINATION

8 . 1           Term and Expiration of Term . The term of this Agreement (the “Term”) shall commence on the A&R Effective Date and, notwithstanding any other

Agreement between the Parties with respect to the payment of milestones or royalties with respect to Licensed Products and Licensed Services have been satisfied (such expiry
of the Term hereinafter referred to as “Expiration”).

Agreement, and/or (c) the gross negligence or willful misconduct of a COH Indemnitee.

5.2.3           Withholding of Taxes. Licensee may withhold from payments due to COH amounts for payment of any withholding tax that is required by law
to be paid to any taxing authority with respect to such payments. Licensee shall provide to COH all relevant documents and correspondence, and shall also provide to COH any
other cooperation or assistance on a reasonable basis as may be necessary to enable COH to claim exemption from such withholding taxes and to receive a full refund of such
withholding tax or claim a foreign tax credit. Licensee shall give COH proper evidence from time to time as to the payment of such tax. The Parties shall cooperate with each

or regulations prohibit both the transmittal and deposit of royalties or other payments, Licensee shall continue to report all such amounts, but may suspend payment for as long
as  such  prohibition  is  in  effect. As  soon  as  such  prohibition  ceases  to  be  in  effect,  all  amounts  that  would  have  been  obligated  to  be  transmitted  or  deposited  but  for  the
prohibition, together with accrued interested thereon, shall promptly be transmitted to COH.

ARTICLE 7: INTELLECTUAL PROPERTY; PATENT PROSECUTION, MAINTENANCE AND ENFORCEMENT.

7.1         Patent Prosecution, Maintenance and Enforcement.

(a)          COH shall be responsible for the preparation, filing, prosecution, and maintenance of all Spacer Patent Rights, using counsel of its choice. COH will
timely provide Licensee with copies of all relevant documentation relating to such prosecution and Licensee shall keep such information confidential. In addition, COH shall
instruct the patent counsel prosecuting Spacer Patent Rights to (i) copy Licensee on patent prosecution documents that are received from or filed with the United States Patent
and Trademark Office and foreign equivalent, as applicable; (ii) if requested by Licensee, provide Licensee with copies of draft submissions to the USPTO prior to filing; and
(iii) give reasonable consideration to the comments and requests of Licensee or its patent counsel, provided that (a) COH reserves the sole right to make all final decisions with
respect to the preparation, filing, prosecution and maintenance of such patent applications and patents; and (b) the patent counsel remains counsel to COH (and shall not jointly
represent  Licensee  unless  requested  by  Licensee  and  approved  by  COH,  and  an  appropriate  engagement  letter  and  conflict  waiver  are  in  effect).  All  patents  and  patent
applications in Spacer Patent Rights, to the extent assignable in whole or in part to COH, shall be assigned to COH.

(b)          COH will not unreasonably refuse to amend any patent application in Spacer Patent Rights to include claims reasonably requested by Licensee to
protect the products contemplated to be sold by Licensee under this Agreement. If Licensee informs COH of other countries or jurisdictions in which it wishes to obtain patent
protection with respect to the Spacer Patent Rights, COH shall prepare, file, prosecute and maintain patent applications in such counties and any patents resulting therefrom
(and, for the avoidance of doubt, such patent applications and patents shall be deemed included in the Spacer Patent Rights). On a country by country and patent by patent basis,
Licensee may elect to surrender any patent or patent application in Spacer Patent Rights in any country upon sixty (60) days advance written notice to COH. Such notice shall
relieve Licensee from the obligation to pay for future patent costs but shall not relieve Licensee from responsibility to pay patent costs incurred prior to the expiration of the
sixty (60) day notice period. Such U.S. or foreign patent application or patent shall thereupon cease to be a Spacer Patent Right hereunder, Licensee shall have no further rights
therein and COH shall be free to license its rights to that particular U.S. or foreign patent application or patent to any other party on any terms.

(c)          Each Party shall promptly provide written notice to the other in the event it becomes aware of any actual or probable infringement of any of the
Spacer  Patent  Rights  in  or  relevant  to  the  Field  or  of  any  Third  Party  claim  regarding  the  enforceability  or  validity  of  any  Spacer  Patent  Rights  (“Infringement  Notice”).
Licensee shall, in cooperation with COH, use reasonable efforts to terminate infringement without litigation.

(d)                    If  infringing  activity  has  not  been  abated  within  ninety  (90)  days  following  the  date  the  Infringement  Notice  takes  effect,  then  Licensee  may,
following consultation with COH, in its sole discretion and at its sole expense, take action against any alleged infringer or in defense of such any claim, provided, that Licensee
has exclusive rights under this Agreement. Any recovery obtained by Licensee as the result of legal proceedings initiated and paid for by Licensee pursuant to this subsection
(d), after deduction of Licensee’s reasonable out-of-pocket expenses incurred in securing such recovery, shall be deemed to be Net Sales of Licensed Products and/or Licensed
Services in the calendar quarter in which such recovery was received and royalties shall be due and payable thereon accordingly.

including but not limited to, reasonable legal fees of counsel that COH selects and retains to represent it in the suit.

(e)                    If  COH  is  involuntarily  joined  in  a  suit  initiated  by  Licensee,  then  the  Licensee  will  pay  any  costs  incurred  by  COH  arising  out  of  such  suit,

(f)          In the event that Licensee declines either to cause such infringement to cease (e.g., by settlement or injunction) or to initiate and thereafter diligently
maintain  legal  proceedings  against  the  infringer  other  than  as  part  of  a  mutually  agreed  upon  bona  fide  strategy,  developed  with  the  guidance  of  outside  patent  counsel,  to
preserve the Spacer Patent Rights, COH may, in its sole discretion and at its sole expense, take action against such alleged infringer or in defense of any such Third Party claim.
Any recovery obtained by COH as the result of any such legal proceedings shall be for the benefit of COH only.

7 . 2         Trademarks. Licensee shall be responsible for the selection, registration, maintenance, and defense of all trademarks for use in connection with the sale or
marketing  of  Licensed  Products  and  Licensed  Services  in  the  Field  in  the  Territory  (the  “ Marks”),  as  well  as  all  expenses  associated  therewith. All  uses  of  the  Marks  by
Licensee or a Sublicensee shall comply in all material respects with all applicable laws and regulations (including those laws and regulations particularly applying to the proper
use and designation of trademarks in the applicable countries). Licensee shall not, without COH’s prior written consent, use any trademarks or house marks of COH (including
the  COH  corporate  name),  or  marks  confusingly  similar  thereto,  in  connection  with  Licensee  commercialization  of  Licensed  Products  or  Licensed  Services  under  this
Agreement  in  any  promotional  materials  or  applications  or  in  any  manner  implying  an  endorsement  by  COH  of  Licensee  or  the  Licensed  Products  or  Licensed  Services.

7.3         Challenge to the Spacer Patent Rights by Licensee.

(a)          COH may terminate this Agreement and, notwithstanding Section 3.3, above, all Sublicenses issued hereunder, upon written notice to Licensee in the
event that Licensee or any of its Affiliates or Sublicensees directly or indirectly asserts a Patent Challenge. “Patent Challenge” means any challenge in a legal or administrative
proceeding to the patentability, validity or enforceability of any of the Spacer Patent Rights (or any claim thereof), including by: (a) filing or pursuing a declaratory judgment
action in which any of the Spacer Patent Rights is alleged to be invalid or unenforceable; (b) citing prior art against any of the Spacer Patent Rights, filing a request for or
pursuing a re-examination of any of the Spacer Patent Rights (other than with COH’s written agreement), or becoming a party to or pursuing an interference; or (c) filing or
pursuing any re-examination, opposition, cancellation, nullity or other like proceedings against any of the Spacer Patent Rights; but excluding any challenge raised as a defense
against a claim, action or proceeding asserted by COH against Licensee, its Affiliates or Sublicensees. In lieu of exercising its rights to terminate under this Section 7.3(a) COH
may  elect  upon  written  notice  to  increase  the  payments  due  under  all  of  Section  4  by  *  percent  (*%),  which  election  will  be  effective  retroactively  to  the  date  of  the
commencement of the Patent Challenge. Licensee acknowledges and agrees that this Section 7.3(a) is reasonable, valid and necessary for the adequate protection of COH’s
interest in and to the Spacer Patent Rights, and that would not have granted to Licensee the licenses under those Spacer Patent Rights, without this Section.

( b )          Payment of COH Patent Expenses. The Parties acknowledge that, prior to the Original Effective Date, COH provided to Licensee documentation
of historic expenses incurred by COH with respect to the drafting, prosecution and maintenance of the Spacer Patent Rights. In consideration of such historic expenditures by
COH, the Parties acknowledge and agree that Licensee has reimbursed COH for such expenses within thirty (30) days of the Original Effective Date.

(c)          After the Original Effective Date, COH shall provide to Licensee an annual invoice and reasonably detailed documentation with respect to COH’s
out-of-pocket expenses incurred with respect to such prosecution and maintenance for the previous year. Licensee shall reimburse COH for * percent of such expenses within
thirty (30) days after receipt of such invoice and documentation.

7 . 4           Marking. Licensee and its Sublicensees shall mark all Licensed Products and all materials related to Licensed Services in such a matter as to conform with

the patent laws of the country to which such Licensed Products are shipped or in which such products are sold and such Licensed Services performed.

negligence, willful misconduct or failure to comply with applicable law by a Licensee Indemnitee or Sublicensee; in each case except to the extent that such Losses are caused
directly  by:  (a)  COH’s  material  breach  of  any  representation  or  warranty  made  by  COH  under  this  Agreement,  (b)  COH’s  material  breach  of  its  obligations  under  this
Agreement, and/or (c) the gross negligence or willful misconduct of a COH Indemnitee.

10.2         Indemnification by COH. COH shall defend, indemnify and hold harmless Licensee and its Affiliates and their respective officers, directors, shareholders,
employees  and  agents  (collectively,  the  “ Licensee Indemnitees”)  from  and  against  any  and  all  Losses  caused  directly  by:  (i)  the  material  breach  of  any  representation  or
warranty made by COH under this Agreement, or (ii) the gross negligence or willful misconduct of a COH Indemnitee, except to the extent that such Losses arise out of or are
in  any  way  attributable  to:  (a)  the  material  breach  of  any  representation  or  warranty  made  by  Licensee  under  this Agreement,  (b)  the  research,  development,  marketing,
approval, manufacture, packaging, labeling, handling, storage, transportation, use, distribution, promotion, marketing or sale of Licensed Products or Licensed Services by or on
behalf of Licensee or a Sublicensee, or (c) the negligence, willful misconduct or failure to comply with applicable law by a Licensee Indemnitee or a Sublicensee.

1 0 . 3         Procedure.  The  indemnities  set  forth  in  this Article  10  are  subject  to  the  condition  that  the  Party  seeking  the  indemnity  shall  forthwith  notify  the
indemnifying Party on being notified or otherwise made aware of a liability, claim, suit, action or expense and that the indemnifying Party defend and control any proceedings
with the other Party being permitted to participate at its own expense (unless there shall be a conflict of interest which would prevent representation by joint counsel, in which
event  the  indemnifying  Party  shall  pay  for  the  other  Party’s  counsel);  provided, that,  the  indemnifying  Party  may  not  settle  the  liability,  claim,  suit,  action  or  expense,  or
otherwise  admit  fault  of  the  other  Party  or  consent  to  any  judgment,  without  the  written  consent  of  the  other  Party  (such  consent  not  to  be  unreasonably  withheld).
Notwithstanding the foregoing, no delay in the notification of the existence of any claim of Loss shall cause a failure to comply with this Section 10.3 as long as such delay shall
not have materially impaired the rights of the indemnifying Party.
