ITEM 1 – BUSINESS

OVERVIEW

PART I

We are a clinical stage biotechnology company focused on translating ground-breaking science into genomic therapies that transform

patients’ lives using our industry-leading platform technologies in genome editing, gene therapy, gene regulation and cell therapy.

We are a leader in the research and development of zinc finger proteins, or ZFPs, a naturally occurring class of proteins found in

humans. We have used our knowledge and expertise to develop a proprietary technology platform in both genome editing and gene
regulation. ZFPs can be engineered to make zinc finger nucleases, or ZFNs, proteins that can be used to specifically modify DNA
sequences by adding or knocking out specific genes, or genome editing, and ZFP transcription factors or ZFP TFs, proteins that can be
used to increase or decrease gene expression, or gene regulation. In the process of developing this platform, we have accrued significant
scientific, manufacturing and regulatory capabilities and know-how that are generally applicable in the broader field of gene therapy and
have capitalized this knowledge into a conventional gene therapy platform based on adeno-associated viral vector, or AAV, cDNA gene
transfer.

Our strategy is to maximize the value and therapeutic use of our technology platforms. In certain therapeutic areas we intend to
capture the value of our proprietary genome editing and gene therapy products by forward integrating into manufacturing, development and
commercial operations. In other therapeutic areas we intend to partner with biopharmaceutical companies to develop products.

We are focused on the development of human therapeutics for diverse diseases with well-characterized genetic causes. We have

several proprietary clinical and preclinical product candidates in development and have strategically partnered certain programs with
biopharmaceutical companies to obtain funding for our own programs and to expedite clinical and commercial development.

We have an ongoing Phase 1/2 clinical trial evaluating SB-525, a gene therapy for the treatment of hemophilia A, a bleeding disorder.

We have ongoing Phase 1/2 clinical trials evaluating three product candidates using our proprietary in vivo genome editing approach: SB-
FIX, for the treatment of hemophilia B, a bleeding disorder, SB-318, for the treatment of Mucopolysaccharidosis Type I, or MPS I, and SB-
913 for the treatment of Mucopolysaccharidosis Type II, or MPS II.  MPS I and MPS II are rare lysosomal storage disorders, or LSDs. We
are also initiating a Phase 1/2 clinical trial evaluating ST-400, developed using our proprietary ZFN-mediated ex vivo cell therapy platform,
for the treatment of beta-thalassemia, a blood disorder. In addition, we have proprietary preclinical and discovery stage programs in other
LSDs and monogenic diseases, including certain central nervous system disorders, cancer immunotherapy, immunology and infectious
disease.

In addition, we have proprietary preclinical programs in other monogenic diseases and LSDs. Our preclinical discovery efforts

include research into potential therapeutic applications of our technology for certain central nervous system disorders, autoimmune
disorders, infectious disease, and others.

In February 2018, we entered into a global collaboration and license agreement with Kite Pharma, Inc., or Kite, a wholly-owned

subsidiary of Gilead Sciences, Inc., or Gilead, for the research, development and commercialization of potential engineered cell therapies
for cancer. In this collaboration, we will work together with Kite on a research program under which we will design ZFNs and AAVs to
disrupt and insert certain genes in T cells and natural killer, or NK, cells, including the insertion of genes that encode chimeric antigen
receptors, or CARs, T-cell receptors, or TCRs and NK-cell receptors, or NKRs, directed to mutually agreed targets. Kite will be responsible
for all clinical development and commercialization of any resulting products.  

In December 2017, we entered into a new research collaboration and license agreement with Pfizer Inc., or Pfizer, for the

development and commercialization of potential gene therapy products that use ZFP TFs to treat amyotrophic lateral sclerosis, or ALS, and
frontotemporal lobar degeneration, or FTLD, linked to mutations of the C9ORF72 gene. Under this agreement, we are working with Pfizer
on a research program to identify, characterize and preclinically develop ZFP TFs that satisfy pre-agreed criteria. Pfizer is responsible for
subsequent development, manufacturing and commercialization of licensed products.

In May 2017, we entered into a global collaboration and license agreement with Pfizer for the research, development and

commercialization of SB-525, our gene therapy product candidate for hemophilia A, and closely related products. Under this agreement,
we are responsible for conducting the Phase 1/2 clinical trial and certain manufacturing activities for SB-525, while Pfizer is responsible
for subsequent worldwide development, manufacturing, marketing and commercialization of SB-525. We and Pfizer may also collaborate
in the research and development of additional AAV-based gene therapy products for hemophilia A.  

4

 
 
We have also established a collaborative partnership with Bioverativ, Inc., or Bioverativ, to research, develop and commercialize
therapeutic gene-edited cell therapy products in hemoglobinopathies, including beta-thalassemia and sickle cell disease, or SCD. We expect
to begin enrolling patients in a Phase 1/2 clinical study in the first half of 2018. Bioverativ is responsible for subsequent development,
manufacturing and commercialization of licensed products.

We have a substantial intellectual property position in the genome editing field including the design, selection, composition and use

of engineered ZFPs to support our research and development activities. As of February 15, 2018, we either owned outright or have
exclusively licensed the commercial rights to over 860 patents issued in the United States and foreign jurisdictions, and over 610 patent
applications pending worldwide.  We continue to license and file new patent applications that strengthen our core and accessory patent
portfolio. We believe that our intellectual property position is a critical element in our ability to research, develop and commercialize
products and services based on genome editing, gene therapy, gene regulation and cell therapy.

In January 2017, we changed our corporate name to “Sangamo Therapeutics, Inc.” to underscore our focus on clinical development

of genomic therapies using our industry-leading platform technologies across genome editing, gene therapy, gene regulation and cell
therapy.

INTRODUCTION TO GENOME EDITING, GENE THERAPY, CELL THERAPY AND GENE REGULATION

DNA, Genes, and Proteins

Deoxyribonucleic acid, or DNA, is present in all cells except mature red blood cells, and encodes the inherited characteristics of all
living organisms. A cell’s DNA is organized in chromosomes as thousands of individual units called genes. Genes encode proteins, which
are assembled through the process of transcription—whereby DNA is transcribed into ribonucleic acid, or RNA,—and, subsequently,
translation—whereby RNA is translated into protein (Figure 1). Proteins are involved in virtually all cell functions. DNA, RNA and
proteins comprise many of the targets for pharmaceutical drug discovery and therapeutic intervention.

Schematic of the relationship between the human genome, DNA, RNA and protein

Figure 1:

The human body is composed of specialized cells that perform different functions and are thus organized into tissues and organs. All
somatic cells in an individual’s body contain the same set of genes. However, only a fraction of these genes are turned on, or expressed, in
an individual human cell at any given time. Genes are regulated (i.e. turned on or turned off) by DNA-binding proteins called transcription
factors in response to a wide variety of stimuli and developmental signals. Distinct sets of genes are

5

 
 
expressed in different cell types. It is this pattern of gene expression that determines the structure, biological function and health of all cells,
tissues and organisms. The aberrant expression of certain genes can lead to disease. Similarly, a mistake, or mutation in the DNA sequence
of a gene, can result in corresponding error in the protein encoded by the gene, which may have serious consequences for the cell and its
function. A number of disorders have been identified as caused by the inheritance of a single defective gene. These so-called monogenic
diseases include hemophilia A and hemophilia B, LSDs such as MPS I and MPS II, beta-thalassemia, SCD, Huntington’s disease and many
others.

ZFPs are Naturally Occurring Transcription Factors in Humans

A transcription factor recognizes and binds to a specific DNA sequence within or near a particular gene and causes expression of that
gene to be “turned on” (activated) or “turned off” (repressed). ZFPs are the most common class of naturally occurring transcription factors
in organisms from yeast to humans. In higher organisms, naturally occurring transcription factors typically comprise two domains: the first
is a DNA-binding domain, (designated in Figure 2 as the “Recognition Domain”), which recognizes a target DNA sequence and thereby
directs the transcription factor to the proper chromosomal location; the second is a functional domain that causes the target gene to be
activated or repressed. To these naturally occurring transcription factors, we have added functional domains which enable genome editing
at the site determined by the ZFP DNA-binding domain.

Schematic of the two-domain structure of a ZFP and its therapeutic functional domain

Figure 2:

ZFNs can be designed for genome editing and ZFP TFs can be designed for gene regulation

Consistent with the modular structure of natural ZFPs, we take a modular approach to the design of the proteins that we engineer.

The ZFP portion of our engineered proteins, the DNA-recognition domain, is typically composed of four to six zinc fingers. Each
individual finger recognizes and binds to a three or four base pair sequence of DNA and multiple fingers can be linked together to recognize
longer stretches of DNA, thereby improving specificity. By modifying the amino acid sequence of a ZFP, we can engineer novel ZFPs
capable of recognizing the DNA sequences of a chosen genomic target. We use the engineered ZFP DNA-binding domain to link to a
functional domain. The ZFP DNA-binding domain brings the functional domain to the target of interest. Our ability to use our highly
specific ZFP technology to precisely target a DNA sequence in a gene of interest provides us with a range of genome editing and gene
regulation functions that can be applied in many different cell types.

Our engineered ZFPs can be attached to a cleavage domain of a restriction endonuclease, an enzyme that cuts DNA, creating a ZFN.
When a pair of ZFNs is bound to the DNA in the correct orientation and spacing, the DNA sequence is cut between the ZFP binding sites.
DNA binding by both ZFNs is necessary for cleavage, and both nuclease of the restriction endonuclease must be present in the correct
orientation to interact with each other, in order to mediate DNA cleavage. This break in the DNA triggers a natural process of DNA repair
in the cell. The repair process can be harnessed to achieve one of several outcomes that may be therapeutically useful (Figure 3). If cells are
simply treated with ZFNs alone, the repair process joins the two ends of the broken DNA together and

6

 
frequently results in the loss or addition of a small amount of genetic material at the site of the break. This disrupts the original DNA
sequence and can result in the expression of a truncated or non-functional protein from the targeted gene, effectively “knocking out” the
gene function. ZFN-mediated genome editing can be used to disrupt genes that are involved in disease pathology. We are using ZFN-
mediated genome editing of the BCL11A erythroid enhancer in hematopoietic stem progenitor cells, or HSPCs, which is designed to be a
single long-lasting treatment for beta-thalassemia (ST-400) and SCD (BIVV-003).

Figure 3:

Schematic of ZFP genome editing and gene regulation

In contrast, if cells with a mutation in a particular gene are treated not only with ZFNs, but also with a DNA sequence that encodes
the correct gene sequence (referred to as a “donor” DNA) and with ZFNs that recognize and bind to sequences flanking the mutation, the
cell’s repair machinery can use the donor as a template to correct the mutated gene.  This ZFN-mediated gene correction enables the
corrected gene to be expressed in its natural chromosomal context and may provide a novel approach for the precise repair of DNA
sequence mutations responsible for certain monogenic diseases. In addition to providing a donor sequence that encodes a complete gene, a
new copy of a gene can also be precisely added into the genome at a specific location. The ability to precisely place a gene-sized segment
of DNA specifically into a pre-determined location in the genome broadens the range of mutations of a gene that can be corrected in a
single step. It also reduces the insertional mutagenesis concerns associated with traditional integrating gene replacement approaches such as
lentiviruses, in which the insertion of a new corrective copy of the gene typically occurs at random locations in the genome. Our In Vivo
Protein Replacement Platform™, or IVPRP™, in which our ZFN technology is used to insert a gene encoding a therapeutic protein into a
location such as the Albumin gene, is an approach that we are investigating for the treatment of hemophilia B (SB-FIX) and LSDs (SB-318
and SB-913), which may potentially provide a single and potentially curative treatment for these diseases.

We are also evaluating ZFP TFs with the potential to control or regulate the expression of a target gene in the desired manner

(Figure 3). For instance, attaching an activation domain to a ZFP will cause a target gene to be expressed at enhanced levels, relative to
expression in an untreated cell. Alternatively, a repression domain causes the gene to be downregulated or completely turned off. Pursuant
to a collaboration agreement with Shire International GmbH, or Shire, we have a preclinical program for Huntington’s disease in which we
are evaluating a ZFP TF designed to differentially down regulate the mutated disease-causing Huntingtin, or HTT, gene, while leaving
expression of the normal gene unchanged.

ZFPs can be designed to accomplish a range of functions in genome editing and gene regulation.

To date, we and our partners have designed, engineered and assembled thousands of ZFPs and have tested many of these proteins for
their affinity, or tightness of binding to their DNA target, as well as their specificity, or preference for their intended DNA target. We have
developed methods for the design, selection and assembly of ZFPs capable of binding to a wide spectrum of DNA

7

 
 
sequences and genes. We have linked ZFPs to endonuclease domains to create highly specific ZFNs and to numerous functional domains to
create gene-specific ZFP TFs. We have demonstrated the ability of these proteins to enable genome editing or gene regulation, of hundreds
of genes in dozens of different cell types and in whole organisms, including non-human primates, or NHPs, mice, rats, rabbits, pigs, fruit
flies, worms, zebrafish and yeast, and in plant species including canola and maize. We and our collaborators have published data from
many of these studies in peer-reviewed scientific journals. ZFNs are currently being used to generate transgenic animals and cell lines that
have specific genetic modifications that make them useful models of human disease. These high value biologic tools are being used by
academic, and biotechnology and pharmaceutical companies for medical research and drug development. Our preclinical data have been
reviewed by advisory bodies such as the National Institute of Health, or NIH, Recombinant Advisory Committee, or RAC, and regulatory
bodies such as the U.S. Food and Drug Administration, or FDA, and we have ongoing clinical trials to evaluate the safety and efficacy of
ZFNs in humans.

We have employed several strategies for the application of our ZFNs depending on the disease or indication. We routinely deliver

our therapeutics as nucleic acids, either as messenger RNA, or mRNA, or encoded in a viral vector such as AAV that the cell then uses to
make the protein form of the ZFN or ZFP TF.  We can deliver ZFNs ex vivo (outside the body) to isolated cells of the blood, such as T
cells, in the case of our clinical HIV, cancer immunotherapy and immunology programs, and HSPCs for our programs in HIV and
monogenic blood diseases such as beta-thalassemia and SCD. We are also developing ZFPs in which we deliver our therapeutic proteins in
vivo, either systemically (directly into the blood stream) as in our in vivo genome editing programs in hemophilia and LSD, or directly into
a specific tissue such as the brain as in our Huntington’s disease program.

ZFPs provide the Opportunity to Develop a New Class of Human Therapeutics

We believe that our ZFP technology provides a unique and proprietary basis for a broad new class of drugs that have differential

technical advantages over small-molecule drugs, protein pharmaceuticals, RNA-based therapeutics, conventional gene therapy approaches
and other genome editing platforms, enabling us to develop therapies for a broad range of unmet medical needs.

We can generate highly specific ZFNs for genome editing and ZFP TFs for gene regulation and have developed multiple delivery

strategies to administer these therapeutics, including using mRNA, AAV, adenovirus, plasmid, and lipid nanoparticles.  As more genes and
DNA sequences are linked to specific diseases, we believe that the clinical breadth and scope of our ZFP applications will continue to
expand.

For example, ZFPs can:

•

•

•

Enable genome editing and gene regulation strategies to address novel drug targets. Engineered ZFNs enable the
efficient disruption, correction or targeted addition of a gene sequence in a very precise fashion, and ZFP TFs enable either
repression or activation of a therapeutically relevant gene in a cell. This gives our technology a degree of flexibility. Direct,
targeted modification of the genome cannot be achieved using conventional gene therapy approaches, antisense RNA,
siRNA, conventional small molecules, antibodies, or other proteins. Our ZFN genome editing technology, which requires
only brief cellular expression of ZFNs, enables the permanent disruption or addition of a therapeutically relevant gene in a
highly targeted fashion. For example, our in vivo genome editing strategy enables targeted insertion of a therapeutic gene
into the genome of liver cells.  This strategy has the potential to provide an extended or life-long clinical benefit in the
treatment of monogenic diseases, such as hemophilia, without the risk of washout of therapeutic genes delivered using
non-integrating vectors such as AAV, or the potentially deleterious issues related to random insertion of therapeutic genes
into the genome by randomly integrating viral vectors such as lentiviral vectors.

Provide therapeutic solutions for targets that cannot be effectively addressed by existing drug modalities. The
sequencing and publication of the human genome and growing information generated by genome-wide association studies
have enabled the identification of both genes and regulatory sequences as potential new therapeutic targets. Many of these
targets have a direct role in disease processes but cannot be bound or modulated for therapeutic purposes by small
molecules, monoclonal antibodies or RNA based therapeutics. Alternative therapeutic approaches are required to modulate
the biological activity of these so-called “non-druggable” targets. One such target is the BCL11A erythroid enhancer, a
regulatory sequence, which we are disrupting using ZFNs in HSPCs in order to elevate levels of fetal globin.  This target is
being developed in collaboration with Bioverativ as a therapeutic approach for beta-thalassemia and SCD.

Provide high specificity and selectivity for targets. ZFNs and ZFP TFs can be designed to act with high specificity. In
addition, as there are only two copies of each gene in a cell, there are generally only two targets per cell for ZFNs and ZFP
TFs, which means that ZFNs and ZFP TFs need only to be available in the cell to engage a small number of targets, which
may reduce the risk of toxicity. In contrast, drugs that act on protein and RNA targets that are naturally present in higher
cellular concentrations may need to be administered in higher concentrations. In addition, because of the higher specificity
there may be fewer “off-target effects.” Many small molecule and RNA-based approaches either

8

 
 
 
affect multiple targets demonstrating so-called “off-target effects” or may be toxic in the concentrations required to be
therapeutically effective.

•

Provides a genome editing platform with superior qualities for therapeutic development. Unlike other less developed
bacterial-based genome editing platforms, such as CRISPR/Cas9 and TALENS, our proprietary ZFN genome editing
technology is based on human proteins that have co-evolved with our complex human genome.  The relative complexity of
the protein-DNA interaction of our ZFN platform and the ability to engineer the entire protein-DNA interface also gives us
the ability to optimize the components of our genome editing technology to drive efficient cutting with specificity. The
ZFN-mediated mechanism is optimized for both gene insertion and gene knockout and over years of developing this
platform, we have engineered our ZFN proteins to provide maximum design density (1:2 base pairs), giving us the
capability to target virtually any sequence of interest and to place a ZFN exactly where we choose with single gene
specificity. This precision is particularly critical for therapeutic gene insertion and correction.  Finally, we have an
established validated process for rapid development of a ZFN clinical lead and have taken our therapeutics candidates
through regulatory review and into human clinical studies where we are able to evaluate both the safety and efficacy of our
approach.

Hemophilia A and B

Hemophilia, a rare bleeding disorder in which the blood does not clot normally. It is also a monogenic disease, or a disease that is

caused by a genetic defect in a single gene. There are several types of hemophilia caused by mutations in genes that encode factors which
help the blood clot and stop bleeding when blood vessels are injured. Individuals with hemophilia experience bleeding episodes after
injuries and spontaneous bleeding episodes that often lead to joint disease such as arthritis. The most severe forms of hemophilia affect
males. The standard treatment for individuals with hemophilia is replacement of the defective clotting factor with regular infusion of
recombinant clotting factors or plasma concentrates. These therapies are expensive and sometimes stimulate the body to produce antibodies
against the factors that inhibit the benefits of treatment. In these situations, other clotting factors such as Factor VII and X may be used to
treat patients.

The most prevalent form of the disease, hemophilia A, is caused by a defect in the clotting Factor 8 gene. According to the National

Hemophilia Foundation and the World Federation of Hemophilia, hemophilia A occurs in about one in every 5,000 male births in the
United States, with approximately 16,000 males currently affected.  Defects in clotting Factor 9 gene lead to hemophilia B.  Hemophilia B
occurs in about one in every 25,000 male births in the United States, with approximately 4,000 males currently affected.

SB-525 – Hemophilia A

We are developing SB-525, a gene therapy product candidate utilizing an AAV carrying a clotting Factor 8 gene construct that is

driven by our proprietary synthetic liver specific promoter. In 2016, we presented preclinical data demonstrating production of
supraphysiological levels of human Factor VIII clotting protein, or hFVIII, in mice and NHP. In these dose-ranging preclinical studies,
mean hFVIII levels of 5 - 230% of normal were observed using AAV doses in the range of 6.00E+11 – 6.00E+12 vg/kg, the most potent
dose response reported in NHPs for a human Factor 8 gene construct at the time.  

In 2017, we initiated a Phase 1/2 clinical trial, the Alta Study, to evaluate the safety and efficacy of SB-525 in adults with severe
hemophilia A. The Alta Study is an open-label, ascending-dose study designed to enroll up to 20 adult subjects across six potential dose
cohorts. In August 2017, we announced that the first subject was treated in our Alta Study. We expect to release preliminary data from the
Alta Study by mid-2018.

SB-525 has been granted Orphan Drug and Fast Track designations by FDA as well as Orphan Medicinal Product designation by the

European Medicines Agency, or EMA.  We are developing SB-525 in collaboration with Pfizer, see “—Collaborations—Pfizer Inc.”

SB-FIX – Hemophilia B

We are developing SB-FIX, an in vivo genome editing product candidate, to treat hemophilia B. Utilizing our ZFN genome editing
technology, we are adding a new therapeutic copy of the Factor 9 gene precisely into the Albumin gene locus in liver cells, and using the
strong endogenous Albumin promoter to drive expression of the newly inserted gene. We believe the potential of this approach to provide a
permanent correction for a patient may be optimal for a pediatric population by reducing or eliminating the need for chronic infusions of
replacement proteins or clotting factor products. We have published data demonstrating the potential utility of this approach for several
different monogenic disease applications in addition to hemophilia B.

Preclinical studies of the Albumin genome editing approach have demonstrated that therapeutic levels of Factor IX clotting protein
could be generated in a dose-dependent manner in NHPs. There were no significant alterations in circulating Albumin levels.  Studies in
mice also demonstrated stable Factor IX production for over one year. Preclinical studies in wildtype mice have demonstrated expression of
therapeutic levels of human clotting Factor IX protein, or hFIX, from the liver and into the blood for the duration of the 60 week study.
Additional preclinical studies in mouse models of hemophilia B demonstrated expression of therapeutic levels of hFIX from the liver and
into the blood, which resulted in the correction of the clotting defect in hemophilia B mice treated with a single dose of SB-FIX. SB-FIX
was also evaluated in preclinical NHP studies and demonstrated dose-dependent, therapeutic levels of hFIX expression, between 20-50% of
normal, in wildtype cynomolgus monkeys, after a single administration of SB-FIX. Levels of hFIX were stable for up to 3 months in treated
NHPs. Furthermore, there was a strong dose-response correlation between the level of gene modification at the Albumin locus and the
levels of hFIX measured in the blood.

In 2016, we initiated a Phase 1/2, open-label, ascending dose clinical trial, the FIXtendz Study, to evaluate safety and efficacy of SB-

FIX in adult males with severe hemophilia B. The FIXtendz Study is designed to enroll up to 12 subjects across three dose cohorts. In
February 2018, the Medicines and Healthcare Products Regulatory Agency, or MHRA, of the United Kingdom granted the Clinical Trial
Authorisation, or CTA, for enrollment of subjects into the ongoing Phase 1/2 clinical trial evaluating SB-FIX for hemophilia B. The CTA
permits evaluation of SB-FIX in both adults and adolescents. Once preliminary safety and efficacy have been

10

 
demonstrated in the ongoing SB-FIX Phase 1/2 clinical trial in adults (18 years of older), we may begin enrolling adolescents (12 - 17 years
of age) into the study.

SB-FIX has been granted Orphan Drug and Fast Track designations by the FDA.

Lysosomal Storage Disorders

LSD are a heterogeneous group of rare inherited disorders including: MPS I, MPS II, Fabry disease, Gaucher disease; and many
others. These disorders are caused by defects in genes that encode proteins known as enzymes, which break down and eliminate unwanted
substances in cells. These enzymes are found in structures called lysosomes which act as recycling sites in cells, breaking down unwanted
material into simple products. A defect in a lysosomal enzyme leads to the accumulation of toxic levels of the substance that the enzyme
would normally eliminate. These toxic levels may cause cell damage which can lead to serious health problems.

MPS I is caused by mutations in the gene encoding the alpha-L-iduronidase, or IDUA, enzyme, resulting in a deficiency of IDUA

enzyme, which is required for the degradation of the glycosaminoglycans, or GAGs, dermatan sulfate and heparin sulfate. The inability to
degrade GAGs leads to their accumulation within the lysosomes throughout the body. Individuals with this mutation experience multi-
organ dysfunction and damage. Depending on the severity of the mutations and degree of residual enzyme activity, affected individuals
may develop enlarged internal organs, joint stiffness, skeletal deformities, corneal clouding, hearing loss and cognition impairments. Three
forms of MPS I, in order of increasing severity, include Scheie, Hurler-Scheie and Hurler syndromes. According to the National MPS
Society, one in 500,000 births in the United States will result in Scheie syndrome, one in 115,000 births in Hurler/Scheie, and one in
100,000 births results in Hurler syndrome. There are approximately 1,000 MPS I patients in the United States.

MPS II is an X-linked disorder primarily affecting males and caused by mutations in the gene encoding the iduronate-2-sufatase, or

IDS, enzyme.  This results in a deficiency of IDS enzyme, which is required for the degradation of GAGs. Similar to MPS I, the inability to
degrade GAGs leads to their accumulation within the lysosomes throughout the body. Individuals with this mutation experience multi-
organ dysfunction and damage. Children with MPS II appear normal at birth but begin showing symptoms of developmental delay by age 2
– 3 years.  Depending on the severity of the mutations and degree of residual enzyme activity, affected individuals may develop delayed
development, enlarged internal organs, cardiovascular disorders, stunted growth and skeletal abnormalities and hearing loss. The disorder is
progressive and symptoms range from mild (normal cognitive function) to severe (cognitively impaired). According to the National MPS
Society, one in 100,000 male births in the United States will result in MPS II. There are approximately 500 MPS II patients in the United
States.

Fabry disease is an X-linked disorder primarily affecting males and caused by a mutation in the gene encoding the alpha-
galactosidase A, or alpha-Gal A, enzyme, resulting in a deficiency of alpha-Gal A enzyme, which is required for the degradation of the
ganglioside globotriaosylceramide, a particular type of fatty substance. The inability to degrade this fatty substance leads to its
accumulation within the lysosomes throughout the body. Individuals with this mutation experience multi-organ dysfunction and damage.
Depending on the severity of the mutations and degree of residual enzyme activity, affected individuals may develop progressive kidney
damage, heart attack, stroke, gastrointestinal complications, corneal opacity, tinnitus and hearing loss. Milder forms of the disorder present
later in life and affect only the heart or kidneys. According to the National Institutes of Health U.S. National Library of Medicine, one in
40,000 to one in 60,000 male births in the United States will result in Fabry disease. There are approximately 2,200 males with Fabry
disease in the United States. This mutation can also occur in females, however is less common and the frequency is unknown.

There are limited treatments currently available for MPS I, MPS II and Fabry disease.  For individuals with MPS I, there are only two

options: hematopoietic stem cell transplantation, or HSCT, for those with the most severe form of the disease (Hurler) and enzyme
replacement therapy, or ERT, for patients with the attenuated forms of the disease (Hurler-Scheie, Scheie).  However, the reported
mortality rate after HSCT is approximately 15% and the survival rate with successful engraftment is 56%. Most patients with milder forms
of the disease receive weekly ERT, usually in a doctor’s office. These IDUA enzyme infusions take on average four to six hours to
administer. Weekly and bi-weekly ERT infusions are the only available options for MPS II and Fabry disease, respectively. Because of the
availability of few treatment options that effectively and safely treat these diseases, there remains significant unmet medical need.

SB-318 – MPS I

We are developing SB-318, an in vivo genome editing product candidate, to treat MPS I.  Using the same approach as our hemophilia

B product candidate, SB-FIX, we are adding a new therapeutic copy of the IDUA gene precisely into the Albumin gene locus in the
genome of liver cells, using the strong endogenous Albumin promoter to drive expression of the newly inserted gene. We believe the
potential of this approach to provide a permanent correction for a patient may be optimal for a pediatric population by reducing or
eliminating the need for chronic ERT infusions.

11

Preclinical mouse model data demonstrated robust levels of IDUA enzyme expression in the liver, blood plasma and spleen of SB-

318 treated mice, resulting in a 10-fold increase in IDUA activity, with sustained elevated levels in the blood plasma over the course of the
two month study. Additional preclinical mouse model data demonstrated stable production of therapeutic levels of IDUA enzyme from the
liver into the circulation and secondary tissues, including the spleen, lung, muscle, heart and brain, after a single intravenous administration
of SB-318. This resulted in the significant reduction of GAG biomarkers in all of the tissues. Behavioral data from Barnes maze tests,
collected at the end of the four month study, demonstrated statistically significant preservation of cognitive learning and memory in mice
treated with SB-318, compared to untreated mice.

In 2017, we initiated an open-label, dose-ascending Phase 1/2 clinical trial, the EMPOWERS Study, to evaluate SB-318 in adult
subjects with attenuated MPS I. The EMPOWERS Study is designed to enroll up to nine subjects across three ascending dose cohorts. We
expect to present preliminary safety and efficacy data from the EMPOWERS Study in 2018. We plan to submit a CTA in the first half of
2018 to initiate enrollment of adolescent and pediatric subjects in the United Kingdom into the Phase 1/2 clinical trial.

SB-318 MPS I has been granted Orphan Drug, Rare Pediatric Disease and Fast Track designations by the FDA, as well as Orphan

Medicinal Product designation by the EMA.

SB-913 – MPS II

We are developing SB-913, an in vivo genome editing product candidate, to treat MPS II.  Similar to SB-318, we are using our ZFN

genome editing technology to add a new therapeutic copy of the IDS gene precisely into the Albumin gene locus in the genome of liver
cells, using the strong endogenous Albumin promoter to drive expression of the newly inserted gene.

Preclinical mouse model data demonstrated robust levels of IDS enzyme expression in the liver, blood plasma and spleen of SB-913

treated mice, resulting in a 100-fold increase in IDS activity, with sustained elevated levels in the blood plasma over the course of the entire
study. Additional preclinical mouse model data demonstrated stable production of therapeutic levels of IDS enzyme from the liver into the
circulation and additional secondary tissues, including the spleen, lung, muscle, heart and brain, after a single intravenous administration of
SB-913. This resulted in the significant reduction of GAG biomarkers across all the tissues. Behavioral data from Barnes maze tests,
collected at the end of the four month study demonstrated statistically significant preservation of cognitive learning and memory in mice
treated with SB-913, compared to untreated mice.

In 2017, we initiated an open-label, dose-ascending Phase 1/2 clinical trial, the CHAMPIONS Study, to evaluate the safety and

efficacy of SB-913 in adult male subjects with attenuated MPS II, designed to enroll up to nine subjects across three ascending dose
cohorts. In November 2017, we announced that the first subject had been treated in the CHAMPIONS Study. In February 2018, we
presented preliminary six-week safety data from the first subject enrolled in the CHAMPIONS Study. The data demonstrated that the
subject tolerated the infusion well. Mild (Grade 1) adverse events related to the study drug were reported on the fourth day after dosing.
These were dizziness, weakness and frequent urination, all of which resolved within one day without treatment. No other adverse events
related to the study drug have been observed. Liver function tests have remained within normal limits for the patient since the infusion. We
expect to present additional safety and efficacy data from the EMPOWERS Study by mid 2018. We plan to submit a CTA in the first half
of 2018 to initiate enrollment of adolescent and pediatric subjects in the United Kingdom into the Phase 1/2 clinical trial.

SB-913 has been granted Orphan Drug, Rare Pediatric Disease and Fast Track designations by the FDA, as well as Orphan

Medicinal Product designation by the EMA.

ST-920 — Fabry Disease

We are developing ST-920 for Fabry disease, a gene therapy product candidate utilizing an AAV, carrying a galactosidase alpha, or

GLA, gene construct, coding for the alpha-Gal A enzyme, driven by our proprietary synthetic liver specific promoter. We are currently
conducting IND-enabling studies for ST-920 and expect to file an IND application with the FDA by mid 2018.

Hemoglobinopathies: Beta-thalassemia and Sickle Cell Disease

Mutations in the gene encoding beta-globin, the oxygen carrying protein of red blood cells, lead to hemoglobinopathies such as beta-

thalassemia and sickle cell disease, or SCD. Both diseases manifest in the months after birth, when patients switch from producing
functional fetal gamma-globin to a mutant form of adult beta-globin, which results in their condition. Naturally occurring increased levels of
fetal hemoglobin have been shown to reduce the severity of both beta-thalassemia and SCD.

Beta-thalassemia is a rare disorder that results in greatly impaired production of healthy red blood cells despite bone marrow over

activity, leading to life-threatening anemia, enlarged spleen, liver and heart, and bone abnormalities. We are focused on Beta-thalassemia
major which is a severe form of thalassemia that requires regular, often monthly, blood transfusions and subsequent iron-chelation therapy
to treat iron overload. The Centers for Disease Control and Prevention, or CDC, estimates that 1,000 people have beta-thalassemia major in
the United States, and an unknown number carry the genetic trait and can pass it on to their children.

In SCD, the mutation causes the red blood cells to form an abnormal sickle or crescent shape. The cells are fragile and deliver less
oxygen to the body’s tissues. They can also get stuck more easily in small blood vessels and break into pieces that can interrupt healthy
blood flow which further decrease the amount of oxygen flowing to body tissues. Almost all patients with SCD experience these painful
vaso-occlusive crises, which can last from hours to days and may cause irreversible organ damage. Current standard of care is to manage
and control symptoms, and to limit the number of crises. Treatments include administration of hydroxyurea, blood transfusions, iron-
chelation therapy, pain medications and antibiotics. The CDC estimates that there are 90,000 to 100,000 Americans living with SCD, which
occurs in approximately 1 out of every 365 African-American births and 1 out of every 16,300 Hispanic-American births.

ST-400 – Beta-thalassemia; BIVV-003 — SCD

We are developing ST-400 for the treatment of beta-thalassemia and our collaboration partner, Bioverativ, is developing BIVV-003

for the treatment of SCD.  Both ST-400 and BIVV-003 are genome-edited cell therapies that use our ZFN genome editing technology to
modify a patient’s own, or autologous, HSPCs to produce functional red blood cells using fetal hemoglobin. Our genome editing
technology can be used in HSPCs to precisely disrupt regulatory sequences that control the expression of key transcriptional regulators,
such as the BCL11A erythroid enhancer sequence, to reverse the switch from expression of the mutant adult beta-globin back to the
production of functional fetal gamma-globin.

The current standard of care for beta-thalassemia includes chronic blood transfusions, while the standard of care for SCD is a bone

marrow transplant, or BMT, of HSPCs from a “matched” related donor, or an allogeneic BMT. However, these therapies are limited due to
the risk of iron overload with blood transfusions, requiring subsequent iron chelation therapy, and the scarcity of matched donors and the
significant risk of Graft versus Host Disease, or GvHD, with BMTs after transplantation of the foreign cells. By performing genome editing
in HSPCs that are isolated from and subsequently returned to the same patient (i.e., an autologous HSPC transplant), our approach has the
potential to address these limitations. The goal of this approach is to develop a one-time long-lasting treatment for beta-thalassemia and
SCD.

Preclinical data from clinical-scale in vitro studies have demonstrated that ST-400 and BIVV-003 can be manufactured by

reproducible, high-level, ZFN-mediated modification in HSPCs mobilized in peripheral blood at clinical production scale (>108 cells), with
an on-target modification efficiency of greater than 80%. Furthermore, erythroid differentiation of enhancer targeted cells showed
modification of both BCL11A erythroid enhancer alleles in more than 50% of the erythroid colonies and resulted in a greater than four-fold
increase in gamma globin mRNA and protein production, compared to controls. Specificity studies of ST-400 and BIVV-003 revealed no
detectable off-target activity using state-of-the art, unbiased, highly sensitive oligo-capture assays.  Preclinical data from in vivo studies in
immune-deficient mice demonstrated robust long-term (19 weeks) engraftment and that targeted gene modification was maintained through
multi-lineage differentiation in the bone marrow and peripheral blood.

Our IND for ST-400 was cleared by the FDA in September 2017, and we have designed an open-label, single arm Phase 1/2 clinical

trial to evaluate the safety and efficacy of ST-400 in up to 6 adult subjects with beta-thalassemia.  We expect to initiate this trial in early
2018.

Bioverativ is our partner for ST-400 and is responsible for the clinical development of BIVV-003 for SCD. For more information

relating to our collaboration with Bioverativ, see “—Collaborations—Bioverativ.”

CNS-Tauopathies

We are using our ZFP-TF gene regulation platform to develop potential gene therapies for tauopathy disorders, including

Alzheimer’s disease and other neurodegenerative diseases. We believe a reduction in tau protein levels can help reduce intracellular tau
protein aggregation and the formation of neurofibrillary tangles in neurons, potentially ameliorating or reversing disease progression. We
believe this approach may have a significant advantage compared to monoclonal antibody-based approaches to Alzheimer’s disease and
other tauopathy disorders because it is designed to selectively down-regulate the tau gene in neurons with the goal of reducing all forms of
the tau protein globally across the CNS. In contrast, monoclonal antibody-based approaches are limited in that they can only bind to certain
forms of tau proteins.

Preclinical studies in wildtype mice demonstrated that a single administration of tau-targeting ZFP-TFs resulted in up to 70%

reduction of tau mRNA and protein expression across the entire CNS, as well as sustained and well-tolerated ZFP-TF expression with
minimal impact on inflammatory markers. Additional preclinical studies in amyloid mouse models of Alzheimer’s disease demonstrated up
to 80% reduction of tau protein levels in the brain and cerebrospinal fluid, as well as significantly reduced neuritic dystrophy after a single
administration of ZFP-TFs in mice with established disease pathology.

We are currently conducting preclinical studies in NHPs to evaluate our ZFP-TFs in larger mammalian species. We intend to seek a

partner with disease area expertise for the clinical development and commercialization of this program.

C9ORF72–linked ALS/FTLD

In December 2017, we entered into a research collaboration and license agreement with Pfizer to develop and commercialize gene

therapy products that use our ZFP TFs to treat ALS and FTLD linked to mutations of the C9ORF72 gene. ALS and FTLD are part of a
spectrum of neurodegenerative disorders caused by mutations in the C9ORF72 gene that involve hundreds of additional repetitions of a six
base pair sequence of DNA. This ultimately leads to the deterioration of motor neurons, in the case of ALS, or neurons in the frontal and
temporal lobes, in the case of FTLD. Currently, there are no cures to halt or reverse the progression of ALS or FTLD. The C9ORF72
mutation is linked to approximately one-third of cases of familial ALS. We and Pfizer plan to investigate allele-specific ZFP-TFs with the
potential to differentiate the mutant C9ORF72 allele from the wildtype allele and to specifically down-regulate expression of the mutant
form of the gene.

We also have research stage programs in other monogenic diseases, immunology and cancer immunotherapy. See “—Collaborations

—Pfizer Inc.,” for more information relating to this agreement.

Huntington’s Disease

Huntington’s disease is an inherited, progressive neurologic disease for which there is no treatment or cure. The disease is caused by
a particular type of mutation in a single gene, the HTT gene. Most patients inherit one normal and one defective or mutant copy of the HTT
gene, which causes Huntington’s disease. The mutation is characterized by expansion of a repeated stretch of DNA sequence within the
gene called a “CAG repeat.” A normal copy of the HTT gene usually has 10 to 29 of these CAG repeats but a defective copy has many
more—generally greater than 39 repeats. While the protein produced by the normal copy of the gene appears to be essential for
development (mice lacking the gene do not survive to birth), the product of the mutated gene is damaging to cells. Symptoms, which
include deterioration of muscle control, cognition and memory, usually develop between 35 and 44 years of age. It is known that the greater
the number of CAG repeats, the earlier the onset. Huntington’s disease is usually fatal within 15 to 20 years after the onset of symptoms.
The disease has a high prevalence for an inherited disorder. According to the Huntington’s Disease Society of America, approximately
30,000 people in the United States have Huntington’s disease. In addition, it is estimated that approximately 200,000 people in the United
States are at risk of developing the disease.  

Research in animal models of the disease has shown that lowering the levels of the mutant HTT protein can prevent, or even reverse,
disease progression. However, to date most “HTT-lowering” methods decrease levels of both the normal and mutant forms of HTT, raising
potential safety concerns given the importance of normal HTT protein. In collaboration with Shire, we are developing ZFP TFs that can
selectively repress the expression of the mutant disease-causing form of HTT while leaving expression levels of the normal gene
unchanged. Preclinical studies in animal models of the disease are ongoing and Shire is responsible for all clinical development activities
including filing the IND application.  For more information on our collaboration with Shire, see “—Collaborations—Shire International
GmbH.”

Legacy Clinical Research Programs

Human Immunodeficiency Virus, or HIV, and Acquired Immunodeficiency Syndrome, or AIDS

HIV infection results in the death of immune system cells, particularly CD4+ T-cells, and thus leads to AIDS, a condition in which

the body’s immune system is depleted to such a degree that the patient is unable to fight off common infections. Ultimately,

14

 
 
 
these patients succumb to opportunistic infections or cancers. According to the most recent data from the CDC, it is estimated that there
were 1.0 million people living with HIV/AIDS in the United States in 2015, and there are now over 36.7 million people living with HIV
and AIDS worldwide.

Current Treatments and Unmet Medical Need

Currently, there are over 30 antiretroviral drugs approved by the FDA to treat people infected with HIV. While these drugs can
suppress virus in the blood to undetectable levels, they cannot eliminate the reservoir of cells containing genomically-integrated HIV from
the body. Hence, individuals infected with HIV need to take antiretroviral drugs continuously. The drugs are expensive and can have
significant side effects over time. There is no therapeutic approach available that protects CD4+ T-cells, suppresses viral load, reduces the
viral reservoir and does not require daily dosing.

SB-728 – HIV/AIDS

SB-728 uses our ZFN-mediated genome editing technology to disrupt the CCR5 gene in cells of a patient’s immune system to make

these cells permanently resistant to HIV infection. CCR5 is a co-receptor for HIV entry into T-cells and if CCR5 is not expressed on the cell
surface HIV cannot infect them or infects them with lower efficiency. The aim of this approach is to provide the patient with a population
of HIV-resistant cells that can fight HIV and opportunistic infections, by mimicking the naturally occurring CCR5 delta-32 mutation that
renders a population of individuals largely resistant to infection by the most common strains of HIV. We are evaluating this genome editing
approach to disrupt the CCR5 gene in both T cells and HSPCs as two potential therapeutic candidates, SB-728-T and SB-728-HSPC,
respectively.

We have conducted several clinical trials with SB-728-T, which were designed to evaluate safety and tolerability of SB-728-T, as

well as the effect of SB-728-T on subjects’ CD4 T-cell counts, levels of CCR5-modified T-cells, viral burden during a treatment
interruption (TI) from anti-retroviral therapy, or ART, and measure of the viral reservoir. The data to date have demonstrated an ability to
efficiently knock out the CCR5 gene in T-cells by ZFN-driven genome editing and grow the cells ex vivo, that a single infusion of SB-728-
T led to proven engraftment, expansion and persistence of T-cells in vivo, sustained increases in CD4 T-cell counts, a significant and
continuous decay of the HIV reservoir and the ability of certain subjects to control their viral loads for prolonged periods in the absence of
ART. Over 100 subjects have been treated to date and the treatment appears to be well-tolerated.

In addition, we have an ongoing investigator-sponsored Phase 1/2 clinical trial (SB-728mR-HSPC) to investigate SB-728-HSPC as a

self-renewable and potentially lifelong source of HIV-resistant immune cells.

We plan to advance the SB-728 program through externally-funded collaborations.

COLLABORATIONS

We have established collaborative and strategic partnerships for several of our therapeutic programs and also for several non-
therapeutic applications of our technology. We will continue to pursue further partnerships when appropriate with selected pharmaceutical
and biotechnology to fund internal research and development activities and to assist in product development and commercialization. We are
applying our ZFN technology platform to several commercial applications in which our products provide us and our strategic partners and
collaborators with potential technical, competitive and economic advantages.

Kite Pharma, Inc.

In February 2018, we entered into a collaboration and license agreement with Kite, a wholly-owned subsidiary of Gilead, for the

research, development and commercialization of potential engineered cell therapies for cancer. Kite will be responsible for all clinical
development and commercialization of any resulting products. Except for confidentiality obligations and certain representations, warranties
and covenants, which are effective upon execution, the effectiveness of the Kite agreement is subject to the expiration or termination of all
applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and other customary closing
conditions.

Subject to the terms of this agreement, we will, upon effectiveness of this agreement, grant Kite an exclusive, royalty-bearing,
worldwide, sublicensable license, under our relevant patents and know-how, to develop, manufacture and commercialize, for the purpose of
treating cancer, specific cell therapy products that may result from the research program and that are engineered ex vivo using selected
ZFNs and AAVs developed under the research program, to express CARs, TCRs or NKRs directed to candidate targets.  

During the research program term and subject to certain exceptions, except pursuant to this agreement, we will be prohibited from

researching, developing, manufacturing and commercializing, for the purpose of treating cancer, any cell therapy product that, as a result of
ex vivo genome editing, expresses a CAR, TCR or NKR that is directed to a target expressed on or in a human cancer cell. After the
research program term concludes and subject to certain exceptions, except pursuant to this agreement, we will be prohibited

15

from developing, manufacturing and commercializing, for the purpose of treating cancer, any cell therapy product that, as a result of ex vivo
genome editing, expresses a CAR, TCR or NKR that is directed to a candidate target.  

Upon the effectiveness of this agreement, we will receive a $150 million upfront payment from Kite. In addition, Kite will

reimburse our direct costs to conduct the joint research program, and Kite will be responsible for all subsequent development,
manufacturing and commercialization of any licensed products. We are also eligible to receive contingent development- and sales-based
milestone payments that could total up to $3.01 billion if all of the specified milestones set forth in this agreement are achieved. Of this
amount, approximately $1.26 billion relates to the achievement of specified research, clinical development, regulatory and first commercial
sale milestones, and approximately $1.75 billion relates to the achievement of specified sales-based milestones if annual worldwide net
sales of licensed products reach specified levels. Each development- and sales-based milestone payment is payable (i) only once for each
licensed product, regardless of the number of times that the associated milestone event is achieved by such licensed product, and (ii) only
for the first ten times that the associated milestone event is achieved, regardless of the number of licensed products that may achieve such
milestone event.  In addition, we will be entitled to receive escalating, tiered royalty payments with a percentage in the single digits based
on potential future annual worldwide net sales of licensed products. These royalty payments will be subject to reduction due to patent
expiration, entry of biosimilar products to the market and payments made under certain licenses for third-party intellectual property.  

Kite has the right to terminate this agreement, in its entirety or on a per licensed product or per candidate target basis, for any reason
after a specified notice period.  Each party has the right to terminate this agreement on account of the other party’s bankruptcy or material,
uncured breach.  

Pfizer Inc.

We have two separate collaboration agreements with Pfizer Inc., or Pfizer.  In May 2017, we entered into an exclusive, global
collaboration and license agreement with Pfizer, pursuant to which we established a collaboration for the research, development and
commercialization of SB-525, our gene therapy product candidate for hemophilia A, and closely related products.

Under this agreement, we are responsible for conducting the Phase 1/2 clinical trial and certain manufacturing activities for SB-525,
while Pfizer is responsible for subsequent worldwide development, manufacturing, marketing and commercialization of SB-525. We may
also collaborate in the research and development of additional AAV-based gene therapy products for hemophilia A.

We received an upfront fee of $70.0 million and are eligible to receive development milestone payments contingent on the

achievement of specified clinical development, intellectual property, regulatory and first commercial sale milestones for SB-525 and
potentially other products. The total amount of potential clinical development, intellectual property, regulatory, and first commercial sale
milestone payments, assuming the achievement of all specified milestones in this agreement, is $475.0 million, which includes up to $300.0
million for SB-525 and up to $175.0 million for other products that may be developed under the agreement, subject to reduction on account
of payments made under certain licenses for third party intellectual property. In addition, Pfizer agreed to pay us royalties for each potential
licensed product developed under the agreement that are an escalating tiered, double-digit percentage of the annual net sales of such
product and are subject to reduction due to patent expiration, entry of biosimilar products to the market and payment made under certain
licenses for third party intellectual property.

Subject to the terms of the agreement, we granted Pfizer an exclusive, worldwide, royalty-bearing license, with the right to grant
sublicenses, to use certain technology controlled by us for the purpose of developing, manufacturing and commercializing SB-525 and
related products. Pfizer granted us a non-exclusive, worldwide, royalty free, fully paid license, with the right to grant sublicenses, to use
certain manufacturing technology developed under the agreement and controlled by Pfizer to manufacture our products that utilize the
AAV delivery system. During a specified period, neither we nor Pfizer will be permitted to clinically develop or commercialize, outside of
the collaboration, certain AAV-based gene therapy products for hemophilia A.

Unless earlier terminated, the agreement has a term that continues, on a per product and per country basis, until the later of (i) the
expiration of patent claims that cover the product in a country, (ii) the expiration of regulatory exclusivity for a product in a country, and
(iii) fifteen years after the first commercial sale of a product in a country.  Pfizer has the right to terminate the agreement without cause in
its entirety or on a per product or per country basis.  The agreement may also be terminated by either party based on an uncured material
breach by the other party or the bankruptcy of the other party.  Upon termination for any reason, the license granted by us to Pfizer to
develop, manufacture and commercialize SB-525 and related products will automatically terminate.  Upon termination by us for cause or
by Pfizer any country or countries, Pfizer will automatically grant us an exclusive, royalty-bearing license under certain technology
controlled by Pfizer to develop, manufacture and commercialize SB-525 in the terminated country or countries. 

In December 2017, we entered into a separate exclusive, global collaboration and license agreement with Pfizer for the

development and commercialization of potential gene therapy products that use ZFP-TFs to treat ALS and FTLD linked to mutations

16

 
 
 
 
 
 
of the C9ORF72 gene. Pursuant to this agreement, we agreed to work with Pfizer on a research program to identify, characterize and
preclinically develop ZFP-TFs that bind to and specifically reduce expression of the mutant form of the C9ORF72 gene.

We received a $12.0 million upfront payment from Pfizer and are eligible to receive up to $60.0 million in development milestone

payments from Pfizer contingent on the achievement of specified preclinical development, clinical development and first commercial sale
milestones, and up to $90.0 million commercial milestone payments if annual worldwide net sales of the licensed products reach specified
levels. In addition, Pfizer will pay us royalties based on an escalating tiered, mid- to high-single digit percentage of the annual worldwide
net sales of the licensed products. These royalty payments are subject to reduction due to patent expiration, entry of biosimilar products to
the market and payments made under certain licenses for third party intellectual property. Each party will be responsible for the cost of its
performance of the research program. Pfizer will be operationally and financially responsible for subsequent development, manufacturing
and commercialization of the licensed products.

Subject to the terms of the agreement, we granted Pfizer an exclusive, royalty-bearing, worldwide, license under our relevant patents

and know-how to develop, manufacture and commercialize gene therapy products that use resulting ZFP-TFs that satisfy pre-
agreed criteria. During a specified period, neither our company nor Pfizer will be permitted to research, develop, manufacture or
commercialize outside of the collaboration any zinc finger proteins that specifically bind to the C9ORF72 gene.

Unless earlier terminated, the agreement has a term that continues, on a per licensed product and per country basis, until the later of

(i) the expiration of patent claims that cover the licensed product in a country, (ii) the expiration of regulatory exclusivity for a licensed
product in a country, and (iii) fifteen years after the first commercial sale of a licensed product in a major market country.  Pfizer also has
the right to terminate the agreement without cause in its entirety or on a per product or per country basis. The agreement may also be
terminated by either party based on an uncured material breach by the other party or the bankruptcy of the other party. The agreement will
also terminate if we are unable to identify any lead candidates for development within a specified period of time or if Pfizer elects not to
advance a lead candidate beyond a certain development milestone within a specified period of time. Upon termination for any reason, the
license granted by us to Pfizer to develop, manufacture and commercialize licensed products under the agreement will automatically
terminate. Upon termination by us for cause or by Pfizer without cause for any licensed product or licensed products in any country or
countries, we will have the right to negotiate with Pfizer to obtain a non-exclusive, royalty-bearing license under certain technology
controlled by Pfizer to develop, manufacture and commercialize the licensed product or licensed products in the terminated country or
countries. 

Following termination by us for Pfizer’s material breach, Pfizer will not be permitted to research, develop, manufacture or
commercialize ZFPs that specifically bind to the C9ORF72 gene for a period of time. Following termination by Pfizer for our material
breach, we will not be permitted to research, develop, manufacture or commercialize ZFPs that specifically bind to the C9ORF72 gene for a
period of time.

Bioverativ Inc.

We are party to an exclusive worldwide collaboration and license agreement with Bioverativ to develop therapeutics for

hemoglobinopathies, focused on beta-thalassemia and SCD. Under the agreement, we are jointly conducting two research programs: the
beta-thalassemia program and the SCD program. In the beta-thalassemia program, we are responsible for all discovery, research and
development activities through the first human clinical trial. In the SCD program, both parties are responsible for research and development
activities through the submission of an IND application for ZFP therapeutics intended to treat SCD. Bioverativ reimburses us for agreed
upon internal and external program-related costs.

Under both programs, Bioverativ is responsible for subsequent worldwide clinical development, manufacturing and

commercialization of licensed products developed under the agreement. At the end of the specified research terms for each program or
under certain specified circumstances, Bioverativ has the right to step in and take over any of our remaining activities. Furthermore, we
have an option to co-promote in the United States any licensed products to treat beta-thalassemia and SCD developed under the agreement,
and Bioverativ will compensate us for such co-promotion activities. Subject to the terms of the agreement, we have granted Bioverativ an
exclusive, royalty-bearing license, with the right to grant sublicenses, to use certain ZFP and other technology controlled by us for the
purpose of researching, developing, manufacturing and commercializing licensed products developed under the agreement. We have also
granted Bioverativ a non-exclusive, worldwide, royalty-free, fully paid license, with the right to grant sublicenses, under our interest in
certain other intellectual property developed pursuant to the agreement. During the term of the agreement, we are not permitted to research,
develop, manufacture or commercialize, outside of the agreement, certain gene therapy products that target genes relevant to the licensed
products.

Under the agreement, we received an upfront license fee of $20.0 million and are eligible to receive development and sales milestone

payments upon the achievement of specified regulatory, clinical development and sales milestones. The total amount of potential
regulatory, clinical development, and sales milestone payments, assuming the achievement of all specified milestones in the agreement, is
$276.3 million. In addition, we will receive royalty payments for each licensed product that are a tiered double-digit percentage of annual
net sales of each product.

17

The agreement may be terminated by (i) us or Bioverativ for the uncured material breach of the other party, (ii) us or Bioverativ for

the bankruptcy or other insolvency proceeding of the other party; (iii) Bioverativ, upon 180 days’ advance written notice to us and
(iv) Bioverativ, for certain safety reasons upon written notice to, and after consultation with, us. As a result, actual future milestone
payments could be lower than the amounts stated above.

Shire International GmbH

We are party to a collaboration and license agreement with Shire International GmbH, or Shire, to research, develop and

commercialize a ZFP therapeutic for treating Huntington’s disease. We received an upfront license fee of $13.0 million. Shire does not
have any milestone payment obligations, but is required to pay single digit percentage royalties to us, up to a specified maximum cap, on
the commercial sales of therapeutic products for Huntington’s disease. We are required to pay single digit percentage royalties to Shire, up
to a specified maximum cap, on commercial sales of therapeutic products from programs returned under the original agreement (which
include blood clotting Factors VIII and IX) that use two zinc fingers.

Pursuant to the agreement, we granted Shire an exclusive, world-wide, royalty-bearing license, with the right to grant sublicenses, to
use our ZFP technology for the purpose of developing and commercializing human therapeutic and diagnostic products for the HTT gene.
During the term of the agreement, we are not permitted to research, develop or commercialize, outside of the agreement, certain products
that target the HTT gene. We satisfied the deliverables and research services responsibilities within the amended arrangement which were
completed in 2017. The agreement may be terminated by (i) us or Shire, in whole or in part, for the uncured material breach of the other
party, (ii) us or Shire for the bankruptcy or other insolvency proceeding of the other party and (iii) Shire, in its entirety, effective upon at
least 90 days’ advance written notice.

Other Partnerships

In addition to our partnerships for the development of human therapeutic applications, we have also licensed our technology in

several other areas, such as plant agriculture and research reagents, including the production of transgenic animals and cell-line
engineering.  These license partners include Dow AgroSciences LLC, Sigma-Aldrich Corporation, Genentech, Inc., Open Monoclonal
Technology, Inc. and F. Hoffmann-La Roche Ltd and Hoffmann-La Roche Inc.

INTELLECTUAL PROPERTY

Patents and licenses are important to our business. Our strategy is to file or license patent applications to protect technology,
inventions and improvements to inventions that we consider important for the development of our genome editing and gene regulation
technology. We seek patent protection and licenses that relate to our technology and candidates in our pipeline and/or may be important to
our future. We have filed numerous patents and patent applications with the United States Patent and Trademark Office, or U.S. PTO, and
foreign jurisdictions. This proprietary intellectual property includes methods relating to the design of zinc finger, Transcription activator-
like effector, or TALE, proteins and Clustered Regularly Interspaced Short Palindromic Repeats, or CRISPR/Cas editing systems,
therapeutic applications of genome editing technology, enabling technologies related to our platform and the use of genome editing across a
variety of applications. We rely on a combination of patent, copyright, trademark, proprietary know–how, continuing technological
innovations, trade secret laws, as well as confidentiality agreements, materials transfer agreements, research agreements and licensing
agreements, to establish and protect our proprietary rights.

In-Licensed Technology

We have licensed intellectual property directed to the design, selection, and use of ZFPs, ZFNs and ZFP TFs for genome editing and

gene regulation from the Massachusetts Institute of Technology, Johnson & Johnson, The Scripps Research Institute, the California
Institute of Technology and the University of Utah. These licenses grant us rights to make, use and sell ZFPs, ZFNs and ZFP TFs under 9
families of patent filings. As of February 15, 2018, these patent filings have resulted in over 10 issued U.S. patents and over 40 granted
foreign patents are still active, with 3 currently pending U.S. patent applications and 8 pending applications in foreign patent offices. We
have non-exclusive licenses from the NIH for intellectual property related to the composition of the AAV5 vector and to methods of
production of AAV, both of which will expire in 2021.

We entered into a patent license agreement with the Massachusetts Institute of Technology, or MIT, in May 1996, as subsequently
amended, whereby MIT granted us a worldwide exclusive license to technology and patents relating to the design, selection and use of ZFPs
for all fields of use, including the right to sublicense. Under the patent license agreement, we are obligated to pay an annual license fee, low
single-digit royalties of product sales, sublicense issuance fees and annual sublicense maintenance fees, a percentage of our sublicense
revenues, and milestone payments upon achievement of certain commercial development milestones. The aggregate milestone payments
under the patent license agreement are $450,000, of which $150,000 has been paid. At our request, the patent license has been amended to
return some of the intellectual property that was added via amendment after the

18

original agreement was put in place.  This does not affect the development of our technology. The patent license agreement still expires
upon the expiration of the last patent covered by the remainder of patents under the license agreement. Based on currently licensed patents,
the patent license agreement will expire in October 2019. MIT may terminate the license agreement upon a material default by us that
remains uncured following written notice. We may terminate the license agreement at any time upon six months’ written notice.

We entered into a sublicense agreement with Johnson & Johnson in May 1996, whereby Johnson & Johnson granted us a worldwide
exclusive sublicense to technology and patents for the research, development and commercialization of human and animal therapeutic and
diagnostic products using engineered ZFPs, including the right to sublicense. These patents were originally exclusively licensed by Johnson
& Johnson from The Scripps Research Institute. Under the sublicense agreement, we will pay low single-digit royalty payments based upon
sales of license products by us or our sublicensees and a milestone payment upon the achievement of a commercial development milestone.
The sublicense agreement expires upon the expiration of the last patent covered by the sublicense agreement. Based on currently issued
patents and currently filed patent applications, the sublicense agreement will expire on or about June 5, 2018. Johnson & Johnson has the
right to terminate the sublicense agreement upon a breach or default by us that remains uncured following written notice of such default.
We may terminate the sublicense agreement at any time upon sixty days’ written notice.

We entered into a license agreement with The Scripps Research Institute in March 2000, as subsequently amended, whereby The

Scripps Research Institute granted us a worldwide exclusive license to technology and patents for the research, development and
commercialization of products and services using engineered ZFPs, excluding the use of these engineered ZFPs in plant agriculture,
therapeutics and diagnostics. Under the license agreement, we are required to pay a low-single digit royalty on sales of licensed products by
us and our sublicensees, subject to an annual minimum. The license agreement expires upon the expiration of the last patent covered by the
license agreement. Based on currently issued patents and currently filed patent applications, the license agreement will expire on or about
May 27, 2018. Each party may terminate the license agreement upon a material default by the other party that remains uncured following
written notice.

We entered into a license agreement with California Institute of Technology, or CalTech, in November 2003, as subsequently
amended, whereby CalTech granted us a worldwide exclusive license to certain patents related to chimeric nucleases for genome targeting
for all fields of use, including the right to sublicense.  In consideration of the license grant, we issued certain shares of our common stock to
CalTech, but have no obligations to make milestone or royalty payments to CalTech.  The license agreement expires upon the expiration of
the intellectual property rights licensed to us. Based on currently issued patents and currently filed patent applications, the license
agreement will expire in September 2023. Each party may terminate the license agreement upon a material default by the other party that
remains uncured following written notice.  We may terminate the agreement at any time upon 30 days written notice.

We entered into a patent license agreement with the University of Utah Research Foundation, in September 2004, as subsequently
amended, whereby Utah granted us a worldwide license to technology and patents relating to the use of ZFNs for all fields of use, including
the right to sublicense. Under the patent license agreement, we are obligated to pay an annual license fee, low single-digit royalties of
product sales, sublicense issuance fees and annual sublicense maintenance fees, a percentage of our sublicense revenues, and milestone
payments upon achievement of certain commercial development milestones. The license agreement expires on the expiration of the last
patent covered by the patent license agreement.  Based on currently issued patents, the license agreement will expire in March 2025.  Utah
may terminate the license agreement upon a default by us that remains uncured following written notice.  We may terminate the agreement
at any time upon 90 days written notice.  

We have entered into licenses potentially useful for specific therapeutic uses of our genome editing technologies with the Regents of
the University of California and the Children's Medical Center Corporation.  The patents included in these licenses relate to CNS disorders
and hemoglobinopathies, respectively. These licenses include 2 patent families, including 3 issued U.S. patents, over 20 pending foreign
patents and 2 pending U.S. patents.

Our Intellectual Property

In addition to our in-licensed patent portfolio, as of February 15, 2018, we had over 150 families of owned or co-owned patent filings,

over 180 issued U.S. patents, over 600 granted foreign patents, over 110 pending U.S. patent applications and over 490 pending foreign
patent applications. These patent filings are directed to the design, composition and use of ZFPs, ZFNs, ZFP TFs, TALE proteins and
CRISPR/Cas systems and other technology related to our programs.

Some of the earliest zinc finger patents in our portfolio began expiring in 2015, with the average expiration of our currently issued

patents expiring being late-2026. However, we have continued to build on this patent portfolio and have been issued additional

19

patents and have applications pending that provide protection for our ZFP technology. These patents in our portfolio may be subject to
Patent Term Adjustment (due to delays in patent prosecution by the USPTO), Patent Term Extension (due to review of a patented product
by a regulatory agency) or terminal disclaimer. Additionally, patents that may be issued from our pending applications will extend the
patent exclusivity of our patent estate. Accordingly, all dates given above for patent expirations are estimates and the actual dates of
expirations may differ.

We believe that our licensed patents and patent applications, as well as our issued patents and pending patent applications, in the
aggregate, will provide us with a substantial intellectual property position in our commercial development of our genome editing, gene
therapy, cell therapy and gene regulation programs. In this regard, patents issued to us, applied for by us, or exclusively and non-
exclusively licensed to us, cover the following types of inventions, processes and products:

•

We have been advised that certain aspects of our technology can give us and our collaborators independence from third party patent

claims to gene sequences. In general, under U.S. patent law, a patent may be obtained for any new and useful process, machine,
manufacture, or composition of matter. An underlying theme of U.S. patent law, as related to biotechnology, is that the sequence of a gene,
as it exists in the chromosome, is not patentable, even when newly discovered, although a cDNA corresponding to the transcription product
of that gene may be in select instances. Accordingly, U.S. patent claims to DNA sequences can cover only isolated cDNAs, or modified
nucleic acid sequences (e.g., a purified DNA fragment or a DNA sequence inserted into a vector). We have been advised that U.S. patent
claims to DNA sequences do not, and cannot, cover gene sequences as they exist in their natural chromosomal environment, and
international patent law is even more stringent than U.S. patent law in this regard. Most current methods for over-expression of a gene or
protein involve the introduction into a cell of a vector containing a DNA encoding the protein to be over-expressed. Because such a vector
contains isolated cDNA sequences that encode the protein, it would be covered by any patent claims to those sequences. In contrast, our
methods for over-expression utilize ZFP TFs that target endogenous genes as they exist in the chromosome. As a result, our gene regulation
methods do not require the use of isolated cDNA sequences encoding the protein to be over-expressed and, our counsel has advised us, do
not infringe patent claims to such sequences. Notwithstanding this advice, we realize that others could take a contrary position that could
result in litigation. While we believe that we would prevail in any such litigation, the uncertainties involved in litigation generally make it
impossible to provide assurance as to the ultimate outcome of such matters. See “Risk Factors—Because it is difficult and costly to protect
our proprietary rights, and third parties have filed patent applications that are similar to ours, we cannot ensure the proprietary protection
of our technologies and products.”

20

 
 
 
 
 
 
 
 
 
 
The patent positions of pharmaceutical and biotechnology firms, including our patent position, are uncertain and involve complex
legal and factual questions for which important legal tenets are largely unresolved and are subject to interpretation and refinement by the
court system. Patent applications may not result in the issuance of patents and the coverage claimed in a patent application may be
significantly reduced before a patent is issued. Although we have filed for patents on some aspects of our technology, we cannot provide
assurances that patents will be issued as a result of these pending applications or that any patent that has been or may be issued will be
upheld. The laws of some foreign countries may not protect our proprietary rights to the same extent as do the laws of the United States.
For example, our issued European patents EP2171052 and EP2527435 have been opposed in Europe. Our EP2281050 case was revoked
during Opposition in November 2016.  Similarly, EP2171052 and EP2527435 underwent Opposition hearings in early 2017. Although
these cases emerged from the Opposition hearings, the opponent filed appeals that are currently underway, and we do not know what the
outcome of these procedures will be. The claims of these patents may be amended such that claim scope is reduced or the patents may be
revoked as a result of these procedures.

In the future, third parties may assert patent, copyright trademark, and other intellectual property rights to technologies that are
important to our business. Any claims asserting that our products infringe or may infringe proprietary rights of third parties, if determined
adversely to us, could significantly harm our business. See “Risk Factors—Because it is difficult and costly to protect our proprietary
rights, and third parties have filed patent applications that are similar to ours, we cannot ensure the proprietary protection of our
technologies and products.”

COMPETITION

We, and our licensed partners, are the leaders in the research, development, and commercialization of DNA binding proteins for
genome editing and regulation of gene expression. We are aware of several companies focused on other methods for editing genes and
regulating gene expression and a limited number of commercial and academic groups pursuing the development of ZFP gene regulation
and genome editing technology. The field of applied gene regulation and genome editing is highly competitive and we expect competition
to persist and intensify in the future from a number of different sources, including pharmaceutical and biotechnology companies; academic
and research institutions; and government agencies that will seek to develop ZFPs as well as technologies that will compete with our ZFP
technology platform, such as TALE proteins and the CRISPR/Cas9 system.

Accordingly, our competitors may succeed in obtaining patent protection, receiving FDA approval, or commercializing competitive

products before us. If we commence commercial product sales, we may be competing against companies with greater marketing and
manufacturing capabilities, areas in which we have limited or no experience. In addition, any product candidate that we successfully
develop may compete with existing products that have long histories of safe and effective use.

Although we are in the clinical development phase of operations and have no current therapeutic product sales, we believe the
following companies, products and/or technologies may potentially be competitive with our technology or our products under development:

•

•

•

•

•

Protein pharmaceuticals under development at pharmaceutical and biotechnology companies such as Pfizer, Baxter
International Inc., Bayer AG, Novo Nordisk A/S, Genzyme Corp., Shire, BioMarin Pharmaceutical Inc., Biogen Inc.,
Acceleron Pharma Inc. and numerous other pharmaceutical and biotechnology firms.

Gene therapy companies developing gene-based products in clinical trials. uniQure N.V.’s product for lipoprotein lipase
deficiency and GlaxoSmithKline plc’s, or GSK, product for severe combined immunodeficiency due to adenosine
deaminase deficiency are approved in Europe. No other gene therapy products have yet been approved. Our competitors
in this category may include, but not be limited to, uniQure N.V., BioMarin Pharmaceutical Inc., bluebird bio, Inc.,
REGENXBIO Inc., Spark Therapeutics, Inc., Dimension Therapeutics, Inc., Voyager Therapeutics, Inc., Shire, Pfizer, and
GSK.

Cell therapy companies developing cell-based products. Our competitors in this category may include Novartis AG,
Adaptimmune Therapeutics PLC, bluebird bio, Inc., Cellectis S.A., Juno Therapeutics, Inc., Kite, Atara Biotherapeutics,
Inc., and Iovance Biotechnologies, Inc..

Nuclease technologies under development for therapeutic applications of genome modification including companies such
as Editas Medicine, Inc., CRISPR Therapeutics AG, Caribou Biosciences, Inc. and Intellia Therapeutics, Inc. developing
the CRISPR/Cas9 system, Cellectis S.A. developing TALE nucleases and meganucleases, bluebird bio, Inc. developing
Homing Endonucleases and MegaTALs and Precision BioSciences, Inc. developing meganucleases.

Antisense therapeutics and RNA interference technology, including RNAi and microRNA, which are technologies that
may compete with us in the development of novel therapeutic products acting through the regulation of gene expression.
These technologies are being developed by several companies including Alnylam Pharmaceuticals, Inc., Ionis
Pharmaceuticals, Inc., Genzyme Corp. and Regulus Therapeutics Inc.

21

 
 
 
 
 
•

•

Small molecules in development from both in-house drug discovery programs of pharmaceutical companies such as Pfizer,
Inc., GSK, Novartis AG and Merck & Co., Inc., as well as from biotechnology companies with expertise and capabilities in
small molecule discovery and development such as Gilead, Genzyme Corp. and Global Blood Therapeutics, Inc., which
has a small molecule product in development for SCD.

Monoclonal antibody companies and product candidates from certain biotechnology firms such as Genentech, Inc. and
Amgen Inc.

We expect to face intense competition from other companies for collaborative arrangements with pharmaceutical and biotechnology
companies for establishing relationships with academic and research institutions, for licenses to proprietary technology and for subjects in
our clinical trials of treatments for rare diseases. These competitors, either alone or with their collaborative partners, may succeed in
developing technologies or products that are more effective or less costly than ours.

Our ability to compete successfully will depend, in part, on our ability to:

•

•

•

•

•

•

•

•

•

develop safe, efficacious and commercially attractive proprietary products;

obtain access to gene transfer technology on commercially reasonable terms;

obtain required regulatory approvals;

attract and retain qualified scientific and product development personnel;

enter into collaborative and strategic partnerships with others, including our competitors, to develop our technology and
product candidates;

obtain and enforce patents, licenses or other proprietary protection for our products and technologies;

formulate, manufacture, market and sell any product that we develop;

develop and maintain products that reach the market first and are technologically superior to or are of lower cost than other
products in the market; and

recruit subjects into our clinical trials in a timely fashion.

MANUFACTURING

We rely on contract manufacturing organizations, or CMOs, to produce our preclinical and clinical product candidates in accordance

with FDA and EMA mandated regulations, also known as current good manufacturing practices, or cGMPs.  We employ a technical
operations staff in the areas of process development, analytical development, quality control, quality assurance, project management, and
manufacturing to facilitate appropriate oversight of our CMOs, support of our regulatory filings and execution of clinical trials.  In 2017,
we expanded our services agreement with Brammer Bio MA, LLC, or Brammer, to provide dedicated capacity to supply our preclinical and
clinical programs. Additionally, we plan to build a cGMP manufacturing facility at our new corporate headquarters in Brisbane, CA. This
facility will be designed to manufacture of Phase 1/2 clinical trial supplies for our pipeline programs. We believe this balanced approach to
manufacturing, investing in internal capacity/capabilities while strengthening our commitment to external capacity, will enable us to meet
our anticipated pipeline needs.

We currently leverage two distinct manufacturing platforms: AAV vector production for our genome editing and gene therapy product
candidates and HSPC modification for our cell therapy product candidates. We use a commercial scale baculovirus manufacturing platform
to manufacture AAV vectors for genome editing and gene therapy, with each AAV vector packaging a different transgene specific to the
target indication or ZFN. The manufacturing process for our HSPC cell therapy product candidates utilizes the patient’s own HSPCs.
These HSPCs are transfected using mRNA to produce ZFNs that target specific DNA sites, resulting in modified HSPCs.

GOVERNMENT REGULATION

In the United States, the FDA regulates biologic products including gene therapy products under the Federal Food, Drug, and
Cosmetic Act, or the FDCA, the Public Health Service Act, or the PHSA, and regulations and guidance implementing these laws. The
FDCA, PHSA and their corresponding regulations govern, among other things, the testing, manufacturing, safety, efficacy, labeling,
packaging, storage, record keeping, distribution, reporting, advertising and other promotional practices involving biologic products.
Applications to the FDA are required before conducting human clinical testing of biologic products. Additionally, each clinical trial
protocol for a gene therapy product candidate is reviewed by the FDA and, in limited instances the National Institutes of Health, or the
NIH, through its Recombinant DNA Advisory Committee, or RAC. FDA approval also must be obtained before marketing of biologic
products. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and

22

 
 
 
 
 
 
 
 
 
 
 
foreign statutes and regulations require the expenditure of substantial time and financial resources and we may not be able to obtain the
required regulatory approvals.

U.S. Biologic Products Development Process

Our product candidates must be approved by the FDA before they may be legally marketed in the United States. The process

required by the FDA before a biologic product candidate may be marketed in the United States generally involves the following:

•

•

•

•

•

•

•

•

•

completion of preclinical laboratory tests and in vivo studies in accordance with the FDA’s current Good Laboratory
Practice, or GLP, regulations and applicable requirements for the humane use of laboratory animals or other applicable
regulations;

submission to the FDA of an application for an IND exemption, which allows human clinical trials to begin unless FDA
objects within 30 days;

approval by an independent institutional review board, or IRB, reviewing each clinical site before each clinical trial may be
initiated;

performance of adequate and well‑controlled human clinical trials according to the FDA’s GCP regulations, and any
additional requirements for the protection of human research subjects and their health information, to establish the safety
and efficacy of the proposed biologic product candidate for its intended use;

preparation and submission to the FDA of a biologics license application (“BLA”) for marketing approval that includes
substantial evidence of safety, purity and potency from results of nonclinical testing and clinical trials;

review of the product by an FDA advisory committee, if applicable;

satisfactory completion of an FDA inspection of the manufacturing facility or facilities where the biologic product candidate
is produced to assess compliance with cGMP requirements and to assure that the facilities, methods and controls are
adequate to preserve the biologic product candidate’s identity, safety, strength, quality, potency and purity;

potential FDA audit of the nonclinical and clinical trial sites that generated the data in support of the BLA; and

payment of user fees and FDA review and approval, or licensure, of the BLA.

Before testing any biologic product candidate in humans, including a gene therapy product candidate, the product candidate must

undergo preclinical testing. Preclinical tests, also referred to as nonclinical studies, include laboratory evaluations of product chemistry,
toxicity and formulation, as well as in vivo studies to assess the potential safety and activity of the product candidate and to establish a
rationale for therapeutic use. The conduct of the preclinical tests must comply with federal regulations and requirements including GLPs.

Concurrent with clinical trials, companies usually must complete some long‑term preclinical testing, such as animal tests of

reproductive adverse events and carcinogenicity, and must also develop additional information about the chemistry and physical
characteristics of the drug and finalize a process for manufacturing the drug in commercial quantities in accordance with cGMP
requirements. The manufacturing process must be capable of consistently producing quality batches of the drug candidate and, among other
things, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final drug product. Additionally,
appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the drug candidate does not
undergo unacceptable deterioration over its shelf life.

If a gene therapy trial is conducted at, or sponsored by, institutions receiving NIH funding for recombinant DNA research, prior to
the submission of an IND to the FDA, a protocol and related documents must be submitted to, and the study registered with, the NIH Office
of Biotechnology Activities, or the OBA, pursuant to the NIH Guidelines for Research Involving Recombinant DNA Molecules, or the
NIH Guidelines. Compliance with the NIH Guidelines is mandatory for investigators at institutions receiving NIH funds for research
involving recombinant DNA. However, many companies and other institutions, not otherwise subject to the NIH Guidelines, voluntarily
follow them. The NIH is responsible for convening the RAC that discusses protocols that raise novel or particularly important scientific,
safety or ethical considerations at one of its quarterly public meetings. The OBA will notify the FDA of the RAC’s decision regarding the
necessity for full public review of a gene therapy protocol. RAC proceedings and reports are posted to the OBA website and may be
accessed by the public.

23

 
 
 
 
 
 
 
 
 
The clinical trial sponsor must submit the results of the preclinical tests, together with manufacturing information, analytical data,

any available clinical data or literature and a proposed clinical protocol, to the FDA as part of the IND. Some preclinical testing may
continue even after the IND is submitted. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA
places the clinical trial on a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the
clinical trial can begin. With gene therapy protocols, if the FDA allows the IND to proceed, but the RAC decides that full public review of
the protocol is warranted, the FDA will request at the completion of its IND review that sponsors delay initiation of the protocol until after
completion of the RAC review process. The FDA also may impose clinical holds on a biologic product candidate at any time before or
during clinical trials due to safety concerns or non‑compliance. If the FDA imposes a clinical hold, trials may not recommence without
FDA authorization and then only under terms authorized by the FDA. Accordingly, we cannot be sure that submission of an IND will result
in the FDA allowing clinical studies to begin, or that, once begun, issues will not arise that suspend or terminate such studies.

Human Clinical Trials Under an IND

Clinical trials involve the administration of the biologic product candidate to healthy volunteers or patients under the supervision

of qualified investigators which generally are physicians not employed by, or under, the control of the trial sponsor. Clinical trials are
conducted under written study protocols detailing, among other things, the objectives of the clinical trial, dosing procedures, subject
selection and exclusion criteria and the parameters to be used to monitor subject safety, including stopping rules that assure a clinical trial
will be stopped if certain adverse events should occur. Each protocol and any amendments to the protocol must be submitted to the FDA as
part of the IND. Clinical trials must be conducted and monitored in accordance with the FDA’s regulations comprising the GCP
requirements, including the requirement that all research subjects provide informed consent.

Further, each clinical trial must be reviewed and approved by an IRB at or servicing each institution at which the clinical trial will
be conducted. An IRB is charged with protecting the welfare and rights of trial participants and considers items such as whether the risks to
individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the
form and content of the informed consent that must be signed by each clinical trial subject, or their legal representative, reviews and
approves the study protocol, and must monitor the clinical trial until completed. Clinical trials involving recombinant DNA also must be
reviewed by an institutional biosafety committee, or IBC, a local institutional committee that reviews and oversees basic and clinical
research that utilizes recombinant DNA at that institution. The IBC assesses the safety of the research and identifies any potential risk to
public health or the environment.

Human clinical trials typically are conducted in three sequential phases that may overlap or be combined:

•

•

•

Phase 1.  The biologic product candidate initially is introduced into a small number of human subjects and tested for safety,
dosage tolerance, absorption, metabolism, distribution, excretion and, if possible, to gain an early understanding of its
effectiveness. Phase 1 clinical trials of gene therapies are typically conducted in patients rather than healthy volunteers.

Phase 2.  The biologic product candidate is evaluated in a limited patient population to identify possible adverse effects and
safety risks, to preliminarily evaluate the efficacy of the product candidate for specific targeted diseases and to determine
dosage tolerance, optimal dosage and dosing schedule.

Phase 3.  Phase 3 clinical trials are commonly referred to as “pivotal” studies, which typically denotes a study which
presents the data that the FDA or other relevant regulatory agency will use to determine whether or not to approve a biologic
product. In Phase 3 studies, the biologic product candidate is administered to an expanded patient population, generally at
multiple geographically dispersed clinical trial sites in adequate and well‑controlled clinical trials to generate sufficient data
to statistically confirm the potency and safety of the product for approval. These clinical trials are intended to establish the
overall risk/benefit ratio of the product candidate and provide an adequate basis for product labeling.

Post‑approval clinical trials, sometimes referred to as Phase 4 clinical trials, may be conducted after initial approval. These clinical

trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication, particularly for long‑term
safety follow‑up.

During all phases of clinical development, regulatory agencies require extensive monitoring and auditing of all clinical activities,
clinical data and clinical trial investigators. Annual progress reports detailing the results of the clinical trials must be submitted to the FDA.

Written IND safety reports must be promptly submitted to the FDA, the NIH and the investigators for: serious and unexpected

adverse events; any findings from other trials, in vivo laboratory tests or in vitro testing that suggest a significant risk for

24

 
 
 
human subjects; or any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or
investigator brochure. The sponsor must submit an IND safety report within 15 calendar days after the sponsor determines that the
information qualifies for reporting. The sponsor also must notify the FDA of any unexpected fatal or life‑threatening suspected adverse
reaction within seven calendar days after the sponsor’s initial receipt of the information.

The FDA or the sponsor or its data safety monitoring board may suspend a clinical trial at any time on various grounds, including
a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate
approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the
biologic product candidate has been associated with unexpected serious harm to patients.

FDA usually recommends that sponsors observe subjects for potential gene therapy‑related delayed adverse events for a 15‑year

period, including a minimum of five years of annual examinations followed by 10 years of annual queries, either in person or by
questionnaire.

Compliance with cGMP Requirements

Manufacturers of biologics must comply with applicable cGMP regulations, including quality control and quality assurance and
maintenance of records and documentation. Manufacturers and others involved in the manufacture and distribution of such products also
must register their establishments with the FDA and certain state agencies. Both domestic and foreign manufacturing establishments must
register and provide additional information to the FDA upon their initial participation in the manufacturing process. Establishments may be
subject to periodic, unannounced inspections by government authorities to ensure compliance with cGMP requirements and other laws.
Discovery of problems may result in a government entity placing restrictions on a product, manufacturer or holder of an approved BLA,
and may extend to requiring withdrawal of the product from the market. The FDA will not approve a BLA unless it determines that the
manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the
product within required specification.

Concurrent with clinical trials, companies usually complete additional preclinical studies and must also develop additional

information about the physical characteristics of the biologic product candidate as well as finalize a process for manufacturing the product
candidate in commercial quantities in accordance with cGMP requirements. To help reduce the risk of the introduction of adventitious
agents or of causing other adverse events with the use of biologic products, the PHSA emphasizes the importance of manufacturing control
for products whose attributes cannot be precisely defined. The manufacturing process must be capable of consistently producing quality
batches of the product candidate and, among other requirements, the sponsor must develop methods for testing the identity, strength,
quality, potency and purity of the final biologic product. Additionally, appropriate packaging must be selected and tested and stability
studies must be conducted to demonstrate that the biologic product candidate does not undergo unacceptable deterioration over its shelf life.

U.S. Review and Approval Processes

The results of the preclinical tests and clinical trials, together with detailed information relating to the product’s CMC and

proposed labeling, among other things, are submitted to the FDA as part of a BLA requesting approval to market the product for one or
more indications.

Under the Prescription Drug User Fee Act, or PDUFA, as amended, each BLA must be accompanied by a significant user fee. The

FDA adjusts the PDUFA user fees on an annual basis. The PDUFA also imposes an annual program fee for approved biologics. Fee
waivers or reductions are available in certain circumstances, including a waiver of the application fee for the first application filed by a
small business.

The FDA reviews a BLA within 60 days of submission to determine if it is substantially complete before the agency accepts it for
filing. The FDA may refuse to file any BLA that it deems incomplete or not properly reviewable at the time of submission and may request
additional information. In that event, the BLA must be resubmitted with the additional information. The resubmitted application also is
subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in‑depth, substantive
review of the BLA.

The FDA reviews the BLA to determine, among other things, whether the proposed product candidate is safe and potent, or

effective, for its intended use, has an acceptable purity profile and whether the product candidate is being manufactured in accordance with
cGMP to assure and preserve the product candidate’s identity, safety, strength, quality, potency and purity. The FDA may refer
applications for novel biologic products or biologic products that present difficult questions of safety or efficacy to an advisory committee,
typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the application
should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers
such recommendations carefully when making decisions. During the product approval process, the FDA also will

25

determine whether a risk evaluation and mitigation strategy, or REMS, is necessary to assure the safe use of the product candidate. REMS
use risk minimization strategies beyond the professional labeling to ensure that the benefits of the product outweigh the potential risks. To
determine whether a REMS is needed, the FDA will consider the size of the population likely to use the product, seriousness of the
disease, expected benefit of the product, expected duration of treatment, seriousness of known or potential adverse events, and whether the
product is a new molecular entity. A REMS could include medication guides, physician communication plans and elements to assure safe
use, such as restricted distribution methods, patient registries and other risk minimization tools. If the FDA concludes a REMS is needed,
the sponsor of the BLA must submit a proposed REMS; the FDA will not approve the BLA without a REMS, if required.

Before approving a BLA, the FDA will inspect the facilities at which the product candidate is manufactured. The FDA will not

approve the product candidate unless it determines that the manufacturing processes and facilities are in compliance with cGMP
requirements and adequate to assure consistent production of the product candidate within required specifications. Additionally, before
approving a BLA, the FDA typically will inspect one or more clinical sites to assure that the clinical trials were conducted in compliance
with IND trial requirements and GCP requirements.

On the basis of the BLA and accompanying information, including the results of the inspection of the manufacturing facilities, the

FDA may issue an approval letter or a complete response letter. An approval letter authorizes commercial marketing of the biologic
product with specific prescribing information for specific indications. A complete response letter generally outlines the deficiencies in the
submission and may require substantial additional testing or information in order for the FDA to reconsider the application. If and when
those deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the BLA, the FDA will issue an approval letter.

If a product candidate receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or
the indications for use may otherwise be limited. Further, the FDA may require that certain contraindications, warnings or precautions be
included in the product labeling. The FDA may impose restrictions and conditions on product distribution, prescribing or dispensing in the
form of a REMS, or otherwise limit the scope of any approval. In addition, the FDA may require post‑marketing clinical trials, sometimes
referred to as Phase 4 clinical trials, designed to further assess a biologic product’s safety and effectiveness, and testing and surveillance
programs to monitor the safety of approved products that have been commercialized.

The FDA has agreed to specified performance goals in the review of BLAs under the PDUFA. One such goal is to review
standard BLAs in 10 months after the FDA accepts the BLA for filing, and priority BLAs in six months, whereupon a review decision is to
be made. The FDA does not always meet its PDUFA goal dates for standard and priority BLAs and its review goals are subject to change
from time to time. The review process and the PDUFA goal date may be extended by three months if the FDA requests or the BLA sponsor
otherwise provides additional information or clarification regarding information already provided in the submission within the last three
months before the PDUFA goal date.

Post‑approval Requirements

Rigorous and extensive FDA regulation of biologic products continues after approval, particularly with respect to cGMP
requirements. Manufacturers are required to comply with applicable requirements in the cGMP regulations, including quality control and
quality assurance and maintenance of records and documentation. Other post‑approval requirements applicable to biologic products include
reporting of cGMP deviations that may affect the identity, potency, purity and overall safety of a distributed product, record‑keeping
requirements, reporting of adverse effects, reporting updated safety and efficacy information and complying with electronic record and
signature requirements. After a BLA is approved, the product also may be subject to official lot release. If the product is subject to official
release by the FDA, the manufacturer submits samples of each lot of product to the FDA, together with a release protocol, showing a
summary of the history of manufacture of the lot and the results of all tests performed on the lot. The FDA also may perform certain
confirmatory tests on lots of some products before releasing the lots for distribution. In addition, the FDA conducts laboratory research
related to the regulatory standards on the safety, purity, potency and effectiveness of biologic products.

A sponsor also must comply with the FDA’s advertising and promotion requirements, such as the prohibition on promoting

products for uses or in patient populations that are not described in the product’s approved labeling (known as “off‑label use”). Discovery
of previously unknown problems or the failure to comply with the applicable regulatory requirements may result in restrictions on the
marketing of a product or withdrawal of the product from the market as well as possible civil or criminal sanctions. In addition, changes to
the manufacturing process or facility generally require prior FDA approval before being implemented and other types of changes to the
approved product, such as adding new indications and additional labeling claims, are also subject to further FDA review and approval.

Additional Regulation

26

Although we currently do not have any products on the market, we may be subject to additional healthcare regulation and
enforcement by the federal government and by authorities in the states and foreign jurisdictions in which we conduct our business. Such
laws include, without limitation, state and federal anti-kickback, fraud and abuse, false claims, privacy and security and physician sunshine
laws and regulations, many of which may become more applicable if our product candidates are approved and we begin commercialization.
If our operations are found to be in violation of any of such laws or any other governmental regulations that apply to us, we may be subject
to penalties, including, without limitation, civil and criminal penalties, damages, fines, the curtailment or restructuring of our operations,
exclusion from participation in federal and state healthcare programs and imprisonment, and additional reporting requirements and
oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these
laws, any of which could adversely affect our ability to operate our business and our financial results. See Risk Factors—“Our relationships
with customers and third-party payors will be subject to applicable anti-kickback, fraud and abuse and other healthcare laws and
regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits
and future earnings.”

Significant uncertainty exists as to the coverage and reimbursement status of any product candidates for which we obtain regulatory

approval, particularly for novel products. In both domestic and foreign markets, sales and reimbursement of any approved products will
depend, in part, on the extent to which third-party payors, such as government health programs, commercial insurance and managed
healthcare organizations provide coverage, and establish adequate reimbursement levels, for such products. Third-party payors are
increasingly challenging the prices charged for medical products and services and imposing controls to manage costs. Third-party payors
may limit coverage to specific products on an approved list, or also known as a formulary, which might not include all of the FDA-
approved products for a particular indication. Additionally, we may need to conduct expensive pharmacoeconomic studies in order to
demonstrate the cost-effectiveness of our products. If third-party payors do not consider our products to be cost-effective compared to other
therapies, the payors may not cover our products after approved as a benefit under their plans or, if they do, the level of reimbursement may
not be sufficient to allow us to sell our products on a profitable basis. See Risk Factors—“Even if we are able to commercialize our product
candidates, the products may not receive coverage and adequate reimbursement from third-party payors in the United States and in other
countries in which we seek to commercialize our products, which could harm our business.”

ITEM 1A – RISK FACTORS

An investment in our common stock involves significant risk. This Form 10-K contains forward-looking information based on our
current expectations. Because our actual results may differ materially from any forward-looking statements made by or on our behalf, this
section includes a discussion of important factors that could affect our actual future results, including, but not limited to, our revenues,
expenses, net loss and net loss per share. You should carefully consider the information described in the following risk factors, together
with the other information appearing elsewhere in this report, before making an investment decision regarding our common stock.

Risks Relating to Development, Commercialization and Regulatory Approval of our Products and Technology

Our success depends substantially on the results of clinical trials of our lead therapeutic programs, and we may not be able to

demonstrate safety and efficacy of our product candidates.

We do not have any products that have gained regulatory approval. We have initiated Phase 1/2 clinical trials evaluating product
candidates for the treatment of hemophilia A (SB-525), hemophilia B (SB-FIX), MPS I (SB-318) and MPS II (SB-913). Our business is
substantially dependent on our ability to obtain regulatory approval for, and, if approved, to successfully commercialize these product
candidates in a timely manner.  Our failure to enroll sufficient patients to conduct the trials, demonstrate safety or obtain positive clinical
trial results, or our inability to meet the expected timeline of clinical trials or release of data for these programs would have a material
adverse effect on our business operations and financial conditions, which may cause a significant decline in our stock price.

Our ability to conduct clinical trials successfully and on a timely basis for these programs is subject to a number of additional risks,

including but are not limited to the following:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

disagreement with the design or implementation of our clinical trials;

the ability to identify and recruit sufficient number of acceptable patients to complete enrollment of trials;

failure to demonstrate that a product candidate is safe and effective for its proposed indication;

the occurrence of unexpected adverse events or toxicity;

disagreement with the FDA on the interpretation of data from preclinical studies or our clinical trial results;

failure of clinical trials to meet the level of statistical significance required for approval;

the insufficiency of data collected from clinical trials of our product candidates to support the submission and filing of a BLA
or other submission or to obtain regulatory approval;

changes in the approval policies or regulations that render our preclinical and clinical data insufficient for approval;

failure to obtain approval of our manufacturing processes or facilities of third-party manufacturers with whom we contract for
clinical and commercial supplies or our own manufacturing facility;

defects in the preparation and manufacturing of our product candidates;

failure by third parties, including vendors, manufacturers and clinical trial organizations, to provide timely and adequate
supplies and services;

development of similar gene therapies by our competitors;  

unexpected costs and expenses and lack of sufficient funding for these programs; and

loss of licenses to critical intellectual properties.

We have not yet reached agreement with regulatory authorities on the development pathway for our product candidates.  As a result,

we have not yet determined what endpoints would support approval for certain of our programs. Due to the novelty of certain programs,
such as SB-318 and SB-913, the endpoints needed to support regulatory approvals may be different than originally anticipated.   Even if we
are able to complete phase 1/2 trials for these programs successfully, we will likely be required to conduct additional clinical trials with
larger patient populations, before obtaining the necessary regulatory approval to commercialize our products.  However, there is no
guarantee that the positive results achieved in earlier trials are indicative of long-term efficacy in late stage clinical trials.  A number of
companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in

28

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
late stage clinical trials even after achieving promising results in earlier-stage clinical trials. If a larger population of patients does not
experience positive results, or if these results are not reproducible, our products may not receive approval from the FDA, which could have
a material adverse effect on our business that would cause our stock price to decline significantly.

Even if a product candidate were to successfully obtain approval from the FDA and comparable foreign regulatory authorities, any

approval might contain significant limitations related to use restrictions for specified age groups, warnings, precautions or
contraindications, or may be subject to burdensome post-approval study or risk management requirements. If we are unable to obtain
regulatory approval for one of our product candidates in one or more jurisdictions, or any approval contains significant limitations, we may
not be able to obtain sufficient funding to continue the development of that product or generate revenues attributable to that product
candidate. Also, any regulatory approval of our current or future product candidates, once obtained, may be withdrawn.

Success in preclinical studies or early clinical trials may not be indicative of results obtained in later trials.

Results from preclinical studies or previous clinical trials are not necessarily predictive of future clinical trial results, and interim results

of a clinical trial are not necessarily indicative of final results. Our product candidates may fail to show the desired safety and efficacy in
clinical development despite demonstrating positive results in preclinical studies or having successfully advanced through initial clinical
trials or preliminary stages of clinical trials.

While we have achieved positive results in preclinical studies of our product candidates for hemophilia A (SB-525), hemophilia B
(SB-FIX), MPS I (SB-318) and MPS II (SB-913), Phase 1/2 clinical trials have only recently begun and there is no guarantee that we can
achieve positive safety and efficacy results.  Furthermore, all four programs are novel in-vivo gene therapy or genome editing therapies that
utilize AAV to deliver therapeutic levels of ZFN into the patient’s blood stream.  The AAV delivery system has not been validated in
human clinical trials previously, and if such delivery system does not meet the safety criteria or cannot produce the desirable efficacy
results we expect, we may be forced to suspend or terminate the affected program.

There is a high failure rate for drugs, biologic products and cell therapies proceeding through clinical trials. Many companies in the
pharmaceutical and biotechnology industries have suffered significant setbacks in late-stage clinical trials even after achieving promising
results in preclinical testing and earlier-stage clinical trials. Data obtained from preclinical and clinical activities are subject to varying
interpretations, which may delay, limit or prevent regulatory approval. In addition, we may experience regulatory delays or rejections as a
result of many factors, including due to changes in regulatory policy during the period of our product candidate development. Any such
delays could materially and adversely affect our business, financial condition, results of operations and prospects.

Our potential products are subject to a lengthy and uncertain regulatory approval process.

The FDA must approve any human therapeutic product before it can be marketed in the United States. The process for receiving
regulatory approval is long and uncertain, and a potential product may not withstand the rigors of testing under the regulatory approval
processes.

Before commencing clinical trials in humans, we must submit an Investigational New Drug, or IND, application to the FDA. The
FDA has 30 days to comment on the application, and if the agency has no comments, we or our commercial partner may begin clinical
trials. While we have stated our intention to file additional IND applications in the future, this is only a statement of intent, and we may not
be able to do so because the associated product candidates may not meet the necessary preclinical requirements. In addition, there can be
no assurance that, once filed, an IND application will result in the actual initiation of clinical trials or that we will be able to meet our
targeted timeline for the initiation of clinical trials. Clinical trials are subject to oversight by institutional review boards and the FDA. In
addition, our proposed clinical studies may require review from the Recombinant DNA Advisory Committee, or RAC, which is the
advisory board to the NIH focusing on clinical trials involving gene transfer.

Clinical trials:

• must be conducted in conformance with the FDA’s good clinical practices, within the guidelines of the International Council

for Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use, or ICH, and other
applicable regulations;

• must meet requirements for Institutional Review Board, or IRB, oversight;

• must follow Institutional Biosafety Committee, or IBC, and NIH RAC guidelines where applicable;

• must meet requirements for informed consent;

•

are subject to continuing FDA or similar foreign government oversight;

29

 
 
 
 
 
 
• may require oversight by a Data Monitorin g Committee, or DMC;

• may require large numbers of test subjects; and

• may be suspended by a commercial partner, the FDA, or us at any time if it is believed that the subjects participating in these
trials are being exposed to unacceptable health risks or if the FDA finds deficiencies in the IND application or the conduct of
these trials.

If we are not able to obtain the necessary regulatory approval to commercialize our products of if such approval is delayed or

suspended, it would have an adverse effect on our business operations and trading price of our common stock.

We may encounter difficulties that may delay, suspend or scale back our efforts to advance additional early research programs

through preclinical development and IND application filings and into clinical development.

We intend to advance early research programs through preclinical development and to file new IND applications for human clinical

trials evaluating the preclinical candidates in our pipeline. The preparation and submission of IND applications requires us to conduct
rigorous and time-consuming preclinical testing, studies, and prepare documentation relating to, among other things, the toxicity, safety,
manufacturing, chemistry and clinical protocol of our product candidates. We may experience unforeseen difficulties that could delay or
otherwise prevent us from executing this strategy successfully. For example, we may encounter problems in the manufacturing of our
products and fail to demonstrate consistency in the formulation of the drug. Our preclinical tests may produce negative or inconclusive
results, which may lead us to decide, or regulators may require us, to conduct additional preclinical testing. If we cannot obtain positive
results in preclinical testing, we may decide to abandon the projects altogether. In addition, our ability to complete and file certain IND
applications depends on the support of our partners and the timely performance of their obligations under relevant collaboration
agreements. If our partners are not able to perform such obligations or if they choose to slow down or delay the progress, we may not be
able to prepare and file the intended IND applications on a timely basis or at all. Furthermore, the filing of several IND applications
involves significant cost and labor, and we may not have sufficient resources and personnel to complete the filing of all intended IND
applications, which may force us to scale back the number of IND applications or forego potential IND applications that we believe are
promising. Any delay, suspension or reduction of our efforts to pursue our preclinical and IND strategy could have a material adverse effect
on our business and cause our stock price to decline.

We may not successfully identify, acquire, develop or commercialize new potential product candidates.

Part of our business strategy is to expand our product candidate pipeline by identifying and validating new product candidates, which
we may develop ourselves, in-license or otherwise acquire from others. In addition, in the event that our existing product candidates do not
receive regulatory approval or are not successfully commercialized, then the success of our business will depend on our ability to expand
our product pipeline through in-licensing or other acquisitions. We may be unable to identify relevant product candidates. If we do identify
such product candidates, we may be unable to reach acceptable terms with any third party from which we desire to in-license or acquire
them.

We may encounter substantial delays in our clinical trials or we may fail to demonstrate safety and efficacy to the satisfaction of

applicable regulatory authorities.

Before obtaining marketing approval from regulatory authorities for the sale of our product candidates, we must conduct extensive
clinical trials to demonstrate the safety and efficacy of the product candidates. Clinical testing is expensive, time consuming and uncertain
as to outcome. We cannot guarantee that any clinical trials will be conducted as planned or completed on schedule, if at all. A failure of one
or more clinical trials can occur at any stage of testing. Events that may prevent successful or timely completion of clinical development
include:

•

•

•

•

•

•

delays in reaching a consensus with regulatory authorities on trial design;

delays in reaching agreement on acceptable terms with prospective CROs and clinical trial sites;

delays in opening clinical trial sites or obtaining required IRB or independent ethics committee approval at each clinical trial site;

delays in recruiting suitable subjects to participate in our clinical trials;

imposition of a clinical hold by regulatory authorities as a result of a serious adverse event or after an inspection of our clinical
trial operations or trial sites;

failure by us, any CROs we engage or any other third parties to adhere to clinical trial requirements;

30

 
 
 
 
 
 
 
 
 
•

•

•

•

•

•

•

•

failure to perform in accordance with FDA good clinical practices, or GCP, or applicable regulatory guidelines in the European
Union and other countries;

delays in the testing, validation, manufacturing and delivery of our product candidates to the clinical sites, including delays by
third parties with whom we have contracted to perform certain of those functions;

delays in having subjects complete participation in a trial or return for post-treatment follow-up;

clinical trial sites or subjects dropping out of a trial;

selection of clinical endpoints that require prolonged periods of clinical observation or analysis of the resulting data;

occurrence of serious adverse events associated with the product candidate that are viewed to outweigh its potential benefits;

occurrence of serious adverse events in trials of the same class of agents conducted by other sponsors; or

changes in regulatory requirements and guidance that require amending or submitting new clinical protocols.

Any inability to successfully complete preclinical and clinical development could result in additional costs to us or impair our ability to
generate revenues from product sales, regulatory and commercialization milestones and royalties. In addition, if we make manufacturing or
formulation changes to our product candidates, we may need to conduct additional studies to bridge our modified product candidates to
earlier versions. Clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize our
product candidates or allow our competitors to bring products to market before we do, which could impair our ability to successfully
commercialize our product candidates and may harm our business, financial condition, results of operations and prospects.

Additionally, if the results of our clinical trials are inconclusive or if there are safety concerns or serious adverse events associated

with our product candidates, we may:

•

•

•

•

•

•

•

•

•

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

obtain approval for indications or patient populations that are not as broad as intended or desired;

obtain approval with labeling that includes significant use or distribution restrictions or safety warnings;

be subject to changes in the way the product is administered;

be required to perform additional clinical trials to support approval or be subject to additional post-marketing testing
requirements;

have regulatory authorities withdraw, or suspend, their approval of the product or impose restrictions on its distribution in the
form of a modified risk evaluation and mitigation strategy;

be subject to the addition of labeling statements, such as warnings or contraindications;

be sued; or

experience damage to our reputation.

We may not be able to find acceptable patients or may experience delays in enrolling patients for our clinical trials, which could
delay or prevent us from proceeding with clinical trials of our product candidates.

Identifying and qualifying patients to participate in clinical trials of our product candidates is critical to our success. The timing of our

clinical trials depends on our ability to recruit patients to participate as well as completion of required follow-up periods. For example,
hemophilia trials often take longer to enroll due to the availability of existing treatments. We have been unable to enroll a patient in our
hemophilia B clinical trial. If we are not able to enroll the necessary number of patients in a timely manner, we may not be able to complete
the clinical trial. We may face similar challenges or delays in our other or future clinical trials. If patients are unwilling to participate in our
gene therapy studies because of negative publicity from adverse events related to the biotechnology or gene therapy fields, competitive
clinical trials for similar patient populations or for other reasons, the timeline for recruiting patients, conducting studies and obtaining
regulatory approval of our product candidates may be delayed. These delays could result in increased costs, delays in advancing our
product candidates, delays in testing the effectiveness of our product candidates or termination of the clinical trials altogether.

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

complete our clinical trials in a timely manner. Patient enrollment and trial completion is affected by factors including:

•

size of the patient population and process for identifying subjects;

design of the trial protocol;

eligibility and exclusion criteria;

perceived risks and benefits of the product candidate under study;

perceived risks and benefits of gene therapy-based approaches to treatment of diseases;

availability of competing therapies and clinical trials;

severity of the disease under investigation;

availability of genetic testing for potential patients;

proximity and availability of clinical trial sites for prospective subjects;

ability to obtain and maintain subject consent;

risk that enrolled subjects will drop out before completion of the trial;

patient referral practices of physicians; and

ability to monitor subjects adequately during and after treatment.

Our current product candidates are being developed to treat rare conditions. We plan to seek initial regulatory approvals in the United

States and, subsequently, the European Union. We may not be able to initiate or continue clinical trials if we cannot enroll a sufficient
number of eligible patients to participate in the clinical trials required by regulatory authorities. Our ability to successfully initiate, enroll
and complete a clinical trial in any foreign country is subject to numerous risks unique to conducting business in foreign countries,
including:

•

•

•

•

•

difficulty in establishing or managing relationships with contract research organizations, or CROs, and physicians;

different standards for the conduct of clinical trials;

absence in some countries of established groups with sufficient regulatory expertise for review of gene therapy protocols;

our inability to locate qualified local consultants, physicians and partners; and

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

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

terminate ongoing or planned clinical trials, any of which would have an adverse effect on our business, financial condition, results of
operations and prospects.

Our product candidates may cause undesirable side effects or have other properties that could delay or prevent their regulatory

approval, limit the commercial potential or result in significant negative consequences following any potential marketing approval.

During the conduct of clinical trials, patients report changes in their health, including illnesses, injuries and discomforts, to their study

doctor. Often, it is not possible to determine whether or not the product candidate being studied caused these conditions, particularly as
many of the diseases we are studying have complex comorbidities. If clinical experience indicates that our product candidates have side
effects or cause serious or life‑threatening side effects, the development of the product candidate may fail or be delayed, or, if the product
candidate has received regulatory approval, such approval may be revoked, which would severely harm our business, prospects, operating
results and financial condition.

There have been several significant adverse side effects in gene therapy treatments in the past, including reported cases of leukemia

and death seen in other trials using other genomic therapies. Gene therapy is still a relatively new approach to disease treatment and
additional adverse side effects could develop. There also is the potential risk of significantly delayed adverse events following exposure to
gene therapy products due to persistent biologic activity of the genetic material or other components of products used to carry the genetic
material. Possible adverse side effects that could occur with treatment with gene therapy products include an immunologic reaction early
after administration that, while not necessarily adverse to the patient’s health, could substantially limit the effectiveness of the treatment.

As we cannot predict whether or when we will obtain regulatory approval to commercialize our product candidates, we cannot

predict the timing of any future revenue from these product candidates.

We cannot commercialize any of our products to generate revenue until the appropriate regulatory authorities have reviewed and
approved the applications for the product candidates. We cannot ensure that the regulatory agencies will complete their review processes in
a timely manner or that we will obtain regulatory approval for any product candidate that we or our collaborators develop. Satisfaction of
regulatory requirements typically takes many years, is dependent upon the type, complexity and novelty of the product and requires the
expenditure of substantial resources. Regulatory approval processes outside the United States include all of the risks associated with the
FDA approval process. In addition, we may experience delays or rejections based upon additional government regulation from future
legislation or administrative action or changes in FDA policy during the period of product development, clinical trials and FDA regulatory
review.

We have limited experience in conducting advanced clinical trials.

We have initiated Phase 1/2 clinical trials evaluating product candidates for hemophilia A (SB-525), hemophilia B (SB-FIX), MPS I

(SB-318) and MPS II (SB-913).  For potential marketing application approval, additional clinical testing will be required, which involves
significantly greater resources, commitments and expertise. Therefore, we may be required to scale up our operations and enter into
collaborative relationships with pharmaceutical companies that could assume responsibility for late-stage development and
commercialization.

We have limited experience in conducting advanced clinical trials and may not possess the necessary resources and expertise to
complete such trials. We have entered into a collaborative agreements to provide funding and assistance in the development of certain
product candidates through the clinical trial process. However, there is no guarantee that we will be able to enter into future collaborative
relationships with third parties that can provide us with the funding and expertise for later stage trials.

We may be unable to obtain additional orphan drug designations or orphan drug exclusivity for any product. If our competitors

are able to obtain orphan drug exclusivity for products that constitute the same drug and treat the same indications as our product
candidates, we may not be able to have competing products approved by the applicable regulatory authority for a significant period of
time.

Regulatory authorities in some jurisdictions, including the United States and the European Union, may designate drugs for relatively
small patient populations as orphan drugs. Under the Orphan Drug Act of 1983, the FDA may designate a product candidate as an Orphan
Drug if it is intended to treat a rare disease or condition, which is generally defined as having a patient population of fewer than 200,000
individuals in the United States, or a patient population greater than 200,000 in the United States where there is no reasonable expectation
that the cost of developing the drug will be recovered from sales in the United States. In the European Union, the EMA’s Committee for
Orphan Medicinal Products grants such designation to promote the development of products that are intended for the diagnosis, prevention
or treatment of a life-threatening or chronically debilitating condition affecting not more than five in 10,000 persons in the European
Union. Additionally, orphan designation is granted for products intended for the diagnosis, prevention or treatment of a life-threatening,
seriously debilitating or serious and chronic condition and when, without incentives, it is unlikely that sales of the drug in the European
Union would be sufficient to justify the necessary investment in developing the drug or biologic product.

Our four most advanced product candidates, SB-525, SB-FIX, SB-318 and SB-913 have all been granted Orphan Drug Designation by

the FDA, and SB-525 and SB-318 and SB-913 have also been designated Orphan Medicinal Products by the EMA.  If we request such
designation for our other current or future product candidates, there can be no assurances that the FDA or the EMA will grant any of our
product candidates such designation. Additionally, such designation does not guarantee that any regulatory agency will accelerate
regulatory review of, or ultimately approve, that product candidate, nor does it limit the ability of any regulatory agency to grant such
designation to product candidates of other companies that treat the same indications as our product candidates prior to our product
candidates receiving exclusive marketing approval.

Generally, if a product candidate with an orphan drug designation receives the first marketing approval for the indication for which it

has such designation, the product is entitled to a period of marketing exclusivity, which precludes the FDA or the EMA from approving
another marketing application for a product that constitutes the same drug treating the same indication for that marketing exclusivity
period, except in limited circumstances. If another sponsor receives such approval before we do (regardless of our orphan drug
designation), we will be precluded from receiving marketing approval for our product for the applicable exclusivity period. The applicable
period is seven years in the United States and 10 years in the European Union. The exclusivity period in the United States can be extended
by six months if the BLA sponsor submits pediatric data that fairly respond to a written request from the FDA for such data. The
exclusivity period in the European Union can be reduced to six years if a product no longer meets the criteria for orphan drug designation
or if the product is sufficiently profitable so that market exclusivity is no longer justified. Orphan drug

33

exclusivity may be revoked if any regulatory agency determines that the request for designation was materially defective or if the
manufacturer is unable to assure sufficient quantity of the product to meet the needs of patients with the rare disease or condition.

Even if we obtain orphan drug exclusivity for a product candidate, that exclusivity may not effectively protect the product candidate

from competition because different drugs can be approved for the same condition. In the United States, even after an orphan drug is
approved, the FDA may subsequently approve another drug for the same condition if the FDA concludes that the latter drug is not the
same drug or is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care. In the
European Union, marketing authorization may be granted to a similar medicinal product for the same orphan indication if:

•

•

•

the second applicant can establish in its application that its medicinal product, although similar to the orphan medicinal product
already authorized, is safer, more effective or otherwise clinically superior;

the holder of the marketing authorization for the original orphan medicinal product consents to a second orphan medicinal
product application; or

the holder of the marketing  authorization for the original orphan medicinal product cannot supply sufficient quantities of orphan
medicinal product.

Commercialization of our technologies will depend, in part, on strategic partnering with other companies. If we are not able to
find partners in the future or if our partners do not diligently pursue product development efforts, we may not be able to develop our
technologies or products, which could slow our growth and decrease the value of our stock.

We expect to rely, to some extent, on our strategic partners to provide funding in support of our research and to perform independent
research and preclinical and clinical testing. Our technology is broad-based, and we do not currently possess the resources necessary to fully
develop and commercialize potential products that may result from our technologies or the resources or capabilities to complete the lengthy
marketing approval processes that may be required for the products. Therefore, we plan to rely on strategic partnerships to help us develop
and commercialize our products.  We have entered into a collaborative agreements to provide funding and assistance in the development of
certain product candidates through the clinical trial process. For example, we have an agreement with Kite for potential engineered cell
therapies for cancer, two separate agreements with Pfizer, one for SB-525 for hemophilia A, and another for ALS/FTLD, and an agreement
with Bioverativ for our beta-thalassemia and SCD product candidates.    

If we are unable to find additional partners or if the partners we are unable or unwilling to advance our programs, or if they do not

diligently pursue product approval, this may slow our progress and adversely affect our ability to generate revenues. In addition, our
partners may sublicense or abandon development programs or we may have disagreements or disputes with our partners, which would
cause associated product development to slow or cease.  In addition, the business or operations of our partners may change significantly
through restructuring, acquisition or other strategic transactions or decisions that may negatively impact their ability to advance our
programs.

There can be no assurance that we will be able to establish further strategic collaborations for our products. We may require
significant time to secure collaborations or partners because we need to effectively market the benefits of our technology to these future
collaborators and partners, which may direct the attention and resources of our research and development personnel and management away
from our primary business operations. Further, each collaboration or partnering arrangement will involve the negotiation of terms that may
be unique to each collaborator or partner. These business development efforts may not result in a collaboration or partnership.

The loss of partnering agreements may delay or terminate the potential development or commercialization of products we may derive

from our technologies, but it may also delay or terminate our ability to test our product candidates. If any partner fails to conduct the
collaborative activities successfully or in a timely manner, the preclinical or clinical development or commercialization of the affected
product candidates or research programs could be delayed or terminated.

Under typical partnering agreements, we would expect to receive revenue for the research and development of our product

candidates based on achievement of specific milestones, as well as royalties based on a percentage of sales of the commercialized products.
Achieving these milestones will depend, in part, on the efforts of our partner as well as our own. If we, or any partner, fail to meet specific
milestones, then the partnership may be terminated, which could reduce our revenues. For more information on risks relating to our third-
party collaborative agreements, see “Risks Relating to our Collaborative Relationships.”

We may be unable to license gene transfer technologies that we may need to commercialize our ZFP technology.

In order to regulate or modify a gene in a cell, the ZFP must be efficiently delivered to the cell. We have licensed certain gene

transfer technologies for our ZFP in research including AAV and mRNA technology. We are evaluating these systems and other

34

 
 
 
technologies that may need to be used in the delivery of ZFP into cells for in vitro and in vivo applications. However, we may not be able to
license the gene transfer technologies required to develop and commercialize our product candidates. We have not developed our own gene
transfer technologies, and we rely on our ability to enter into license agreements to provide us with rights to the necessary gene transfer
technology. Our approach has been to license appropriate technology as required. The inability to obtain a license to use gene transfer
technologies with entities which own such technology on reasonable commercial terms, if at all, could delay or prevent the preclinical
evaluation, drug development collaborations, clinical testing, and/or commercialization of our therapeutic product candidates.

Our gene regulation and genome editing technology is relatively new, and if we are unable to use this technology in all our

intended applications, it would limit our revenue opportunities.

Our technology involves a relatively new approach to gene regulation and genome editing. Although we have generated ZFPs for

thousands of gene sequences, we have not created ZFPs for all gene sequences and may not be able do so, which could limit the usefulness
of our technology. In addition, while we have demonstrated the function of engineered ZFNs and ZFP TFs in mammalian cells, yeast,
insects, plants and animals, we have not yet demonstrated clinical efficacy of this technology in a controlled clinical trial in humans, and the
failure to do so could restrict our ability to develop commercially viable products. If we, and our collaborators or strategic partners, are
unable to extend our results to new commercially important genes, experimental animal models, and human clinical studies, we may be
unable to use our technology in all its intended applications.

The expected value and utility of our ZFNs and ZFP TFs is in part based on our belief that the targeted editing of genes or specific
regulation of gene expression may enable us to develop a new therapeutic approach as well as to help scientists better understand the role
of genes in disease, and to aid their efforts in drug discovery and development. We also believe that ZFP-mediated targeted genome editing
and gene regulation will have utility in agricultural applications. There is only a limited understanding of the role of specific genes in all
these fields. Life sciences companies have developed or commercialized only a few products in any of these fields based on results from
genomic research or the ability to regulate gene expression. We, our collaborators or our strategic partners, may not be able to use our
technology to identify and validate drug targets or to develop commercial products in the intended markets.

Effective delivery of ZFNs and ZFP TFs into the appropriate target cells and tissues is critical to the success of the therapeutic
applications of our ZFP technology. In order to have a meaningful therapeutic effect, these products must be delivered to sufficient numbers
of cells in the targeted tissue. The ZFN or ZFP TF must be present in that tissue for sufficient time to effect either modification of a
therapeutically relevant gene or regulation of its expression. In our current clinical and preclinical programs, we administer these product
candidates as a nucleic acid that encodes the ZFN or ZFP TF. We use different formulations to deliver the ZFN or ZFP TF depending on
the required duration of expression, the targeted tissue and the indication that we intend to treat, including our proprietary AAV delivery
system. However, there can be no assurances that we will be able to effectively deliver our ZFNs and ZFP TFs to produce a beneficial
therapeutic effect.

We are conducting proprietary research to discover new product candidates. These programs increase our financial risk of
product failure, may significantly increase our research expenditures, and may involve conflicts with future collaborators and strategic
partners.

Our proprietary research programs consist of research that is funded solely by us or by grant funding and in which we retain exclusive

rights to therapeutic products generated by such research. This is in contrast to certain of our research programs that may be funded by
corporate partners in which we may share rights to any resulting products. Conducting proprietary research programs may not generate
corresponding revenue and may create conflicts with our collaborators or strategic partners over rights to our intellectual property with
respect to our proprietary research activities. Any conflict with our collaborators or strategic partners could reduce our ability to enter into
future collaborations or partnering agreements and negatively impact our relationship with existing collaborators and partners that could
reduce our revenue and delay or terminate our product development. As we continue to focus our strategy on proprietary research and
therapeutic development, we expect to experience greater business risks, expend significantly greater funds and require substantial
commitments of time from our management and staff.

Even if our technology proves to be effective, it still may not lead to commercially viable products.
Even if our collaborators or strategic partners are successful in using our ZFP technology in drug discovery, protein production,

therapeutic development or other areas in which we have licensed our technology, such as plant agriculture, they may not be able to
commercialize the resulting products or may decide to use other methods competitive with our technology. To date, no company has
received marketing approval or has developed or commercialized any therapeutic or agricultural products based on our ZFP technology.
Should our technology fail to provide safe, effective, useful or commercially viable approaches to the discovery and development of these
products, this would significantly limit our business and future growth and would adversely affect our value.

35

Even if our product development efforts are successful and even if the requisite regulatory approvals are obtained, our products

may not gain market acceptance among physicians, patients, healthcare payers and the medical community.

Even if we obtain regulatory approval for any of our product candidates that we may develop or acquire in the future, the product may

not gain market acceptance among physicians, healthcare payors, patients or the medical community. Market acceptance of any of our
product candidates for which we receive approval depends on a number of factors, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

the efficacy and safety of such product candidates as demonstrated in clinical trials;

the clinical indications and patient populations for which the product candidate is approved;

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

the adoption of novel gene therapies by physicians, hospitals and third-party payors;

the potential and perceived advantages of product candidates over alternative treatments;

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

any restrictions on use together with other medications;

the prevalence and severity of any side effects;

product labeling or product insert requirements of the FDA or other regulatory authorities;

the timing of market introduction of our products as well as competitive products;

the development of manufacturing and distribution processes for our product candidates;

the cost of treatment in relation to alternative treatments;

the availability of coverage and adequate reimbursement and pricing by third-party payors and government authorities and
the willingness of patients to pay out-of-pocket in the absence of coverage by third-party payors;

relative convenience and ease of administration; and

the effectiveness of our sales and marketing efforts and those of our collaborators.

If any of our product candidates are approved but fail to achieve market acceptance among physicians, patients, healthcare payors or

treatment centers, we will not be able to generate significant revenues, which would compromise our ability to become profitable.

Even if we are able to commercialize our product candidates, the products may not receive coverage and adequate reimbursement
from third-party payors in the United States and in other countries in which we seek to commercialize our products, which could harm
our business.

Our ability to commercialize any product successfully will depend, in part, on the extent to which coverage and adequate

reimbursement for these products and related treatments will be available from government health administration authorities, private health
insurers and other organizations.

Government authorities and third-party payors, such as private health insurers and health maintenance organizations, determine which

medications they will cover and establish reimbursement levels. A primary trend in the healthcare industry is cost containment.
Government authorities and third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for
particular medications. Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from
list prices and are challenging the prices charged for medical products. Third-party payors may also seek additional clinical evidence,
beyond the data required to obtain regulatory approval, demonstrating clinical benefits and value in specific patient populations before
covering our products for those patients. We cannot be sure that coverage and adequate reimbursement will be available for any product
that we commercialize and, if reimbursement is available, what the level of reimbursement will be. Coverage and reimbursement may
impact the demand for, or the price of, any product candidate for which we obtain regulatory approval. If reimbursement is not available or
is available only at limited levels, we may not be able to successfully commercialize any product candidate for which we obtain regulatory
approval.

There may be significant delays in obtaining coverage and reimbursement for newly approved drugs, and coverage may be more
limited than the purposes for which the drug is approved by the FDA or comparable foreign regulatory authorities. Moreover, eligibility for
coverage and reimbursement does not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research,
development, manufacture, sale and distribution. Interim reimbursement levels for new drugs, if applicable, may

36

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
also not be sufficient to cover our costs and may only be temporary. Reimbursement rates may vary according to the use of the drug and the
clinical setting in which it is used, may be based on reimbursement levels already set for lower cost drugs and may be incorporated into
existing payments for other services. Net prices for drugs may be reduced by mandatory discounts or rebates required by government
healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where
they may be sold at lower prices than in the United States. Third-party payors in the United States often rely upon Medicare coverage
policy and payment limitations in setting their own reimbursement policies. Our inability to promptly obtain coverage and profitable
reimbursement rates from both government-funded and private payors for any approved products that we develop could have a material
adverse effect on our operating results, our ability to raise capital needed to commercialize products and our overall financial condition.

Recently enacted and future legislation, including potentially unfavorable pricing regulations or other healthcare reform
initiatives, may increase the difficulty and cost for us to obtain regulatory approval of and commercialize our product candidates and
affect the prices we may obtain.

The regulations that govern, among other things, regulatory approvals, coverage, pricing and reimbursement for new drug products

vary widely from country to country. In the United States and some foreign jurisdictions, there have been a number of legislative and
regulatory changes and proposed changes regarding the healthcare system that could prevent or delay regulatory approval of our product
candidates, restrict or regulate post-approval activities and affect our ability to successfully sell any product candidates for which we obtain
regulatory approval. In particular, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and
Education Reconciliation Act, collectively, the Affordable Care Act, was enacted, which substantially changes the way health care is
financed by both governmental and private insurers, and significantly impacts the U.S. pharmaceutical industry. The Affordable Care Act
and its implementing regulations, among other things, addressed a new methodology by which rebates owed by manufacturers under the
Medicaid Drug Rebate Program are calculated for certain drugs and biologics, including our product candidates, that are inhaled, infused,
instilled, implanted or injected, increased the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate
Program, extended the Medicaid Drug Rebate Program to utilization of prescriptions of individuals enrolled in Medicaid managed care
organizations, subjected manufacturers to new annual fees and taxes for certain branded prescription drugs, provided incentives to
programs that increase the federal government’s comparative effectiveness research and established 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 the manufacturer’s outpatient drugs to be covered under
Medicare Part D.

Some of the provisions of the Affordable Care Act have yet to be fully implemented, and there have been legal and political challenges

to certain aspects of the Affordable Care Act. Since January 2017, President Trump has signed two executive orders and other directives
designed to delay, circumvent, or loosen certain requirements mandated by the Affordable Care Act. Concurrently, Congress has
considered legislation that would repeal or repeal and replace all or part of the Affordable Care Act. While Congress has not passed repeal
legislation, the Tax Cuts and Jobs Act of 2017 includes a provision repealing, effective January 1, 2019, the tax-based shared responsibility
payment imposed by the Affordable Care Act on certain individuals who fail to maintain qualifying health coverage for all or part of a year
that is commonly referred to as the “individual mandate”. Additionally, on January 22, 2018 President Trump signed a continuing
resolution on appropriations for fiscal year 2018 that delayed the implementation of certain Affordable Care Act-mandated fees. Congress
may consider other legislation to repeal or replace elements of the Affordable Care Act.

Other legislative changes have been proposed and adopted in the United States since the Affordable Care Act was enacted. In August

2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select
Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through
2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs. This
includes aggregate reductions of Medicare payments to providers of 2% per fiscal year, which went into effect in April 2013, and, due to
subsequent legislative amendments to the statute, including the Bipartisan Budget Act of 2018, will remain in effect through 2027 unless
additional Congressional action is taken. In January 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, or
the ATRA, which, among other things, further reduced Medicare payments to several providers, including hospitals and cancer treatment
centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.

Also, there has been heightened governmental scrutiny recently over pharmaceutical pricing practices in light of the rising cost of
prescription drugs and biologics. Such scrutiny has resulted in several recent Congressional inquiries and proposed and enacted federal and
state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and
manufacturer patient programs, and reform government program reimbursement methodologies for pharmaceutical products, some of
which are included in the Trump administration’s budget proposal for fiscal year 2019. At the federal level, Congress and the Trump
administration have each indicated that it will continue to seek new legislative and/or administrative measures to control drug costs. At the
state level, legislatures have become increasingly active in passing legislation and implementing regulations designed to control
pharmaceutical and biological product pricing, including price or patient reimbursement constraints,

37

discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, have been
designed to encourage importation from other countries and bulk purchasing.

There have been, and likely will continue to be, legislative and regulatory proposals at the foreign, federal and state levels directed at

broadening the availability of healthcare and containing or lowering the cost of healthcare. We cannot predict the initiatives that may be
adopted in the future. The continuing efforts of the government, insurance companies, managed care organizations and other payors of
healthcare services to contain or reduce costs of healthcare and/or impose price controls may adversely affect:

•

•

•

•

•

the demand for our product candidates, if we obtain regulatory approval;

our ability to set a price that we believe is fair for our products;

our ability to generate revenue and achieve or maintain profitability;

the level of taxes that we are required to pay; and

the availability of capital.

Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from

private payors, which may adversely affect our future profitability.

Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities

for pharmaceutical products. 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 regulatory approvals of our product candidates, if
any, may be.

In the United States, the European Union and other potentially significant markets for our product candidates, government authorities
and third-party payors are increasingly attempting to limit or regulate the price of medical products and services, particularly for new and
innovative products and therapies, which has resulted in lower average selling prices. For example, in the United States, there have been
several recent Congressional inquiries and proposed bills designed to, among other things, bring more transparency to drug pricing, review
the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for
drugs. Furthermore, the increased emphasis on managed healthcare in the United States and on country and regional pricing and
reimbursement controls in the European Union will put additional pressure on product pricing, reimbursement and usage, which may
adversely affect our future product sales and results of operations. These pressures can arise from rules and practices of managed care
groups, judicial decisions and governmental laws and regulations related to Medicare, Medicaid and healthcare reform, pharmaceutical
reimbursement policies and pricing in general.

Price controls may be imposed in foreign markets, which may adversely affect our future profitability.

In some countries, particularly member states of the European Union, the pricing of prescription drugs is subject to governmental

control. In these countries, pricing negotiations with governmental authorities can take considerable time after receipt of regulatory
approval for a product. In addition, there can be considerable pressure by governments and other stakeholders on prices and reimbursement
levels, including as part of cost containment measures. Political, economic and regulatory developments may further complicate pricing
negotiations, and pricing negotiations may continue after reimbursement has been obtained. Reference pricing used by various European
Union member states and parallel distribution, or arbitrage between low-priced and high-priced member states, can further reduce prices. In
some countries, we, or our collaborators, may be required to conduct a clinical trial or other studies that compare the cost-effectiveness of
our product candidates to other available therapies in order to obtain or maintain reimbursement or pricing approval. Publication of
discounts by third-party payors or authorities may lead to further pressure on the prices or reimbursement levels within the country of
publication and other countries. If reimbursement of our products is unavailable or limited in scope or amount, or if pricing is set at
unsatisfactory levels, our business could be adversely affected.

Even if we complete the necessary preclinical and clinical studies, we cannot predict when or if we will obtain regulatory approval

to commercialize a product candidate or the approval may be for a more narrow indication than we expect.

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

38

 
 
 
 
 
of certain product candidates for pediatric use is an important part of our current business strategy, and if we are unable to obtain regulatory
approval for the desired age ranges, our business may suffer.

Even if we obtain regulatory approval for a product candidate, our products will remain subject to regulatory scrutiny.
Even if we obtain regulatory approval in a jurisdiction, the regulatory authority may still impose significant restrictions on the
indicated uses or marketing of our product candidates, or impose ongoing requirements for potentially costly post-approval studies, post-
market surveillance or patient or drug restrictions. For example, the FDA typically advises that patients treated with gene therapy undergo
follow-up observations for potential adverse events for a 15-year period. Additionally, the holder of an approved BLA is obligated to
monitor and report adverse events and any failure of a product to meet the specifications in the BLA. The holder of an approved BLA must
also submit new or supplemental applications and obtain FDA approval for certain changes to the approved product, product labeling or
manufacturing process. Advertising and promotional materials must comply with FDA rules and are subject to FDA review, in addition to
other potentially applicable federal and state laws.

In addition, product manufacturers and their facilities are subject to payment of user fees and continual review and periodic inspections

by the FDA and other regulatory authorities for compliance with good manufacturing practices, or GMP, and adherence to commitments
made in the BLA. If we or a regulatory agency discovers previously unknown problems with a product such as adverse events of
unanticipated severity or frequency, or problems with the facility where the product is manufactured, a regulatory agency may impose
restrictions relative to that product or the manufacturing facility, including requiring recall or withdrawal of the product from the market or
suspension of manufacturing.

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

may:

•

•

•

•

•

•

•

issue a warning letter asserting that we are in violation of the law;

seek an injunction or impose civil or criminal penalties or monetary fines;

suspend or withdraw regulatory approval;

suspend any ongoing clinical studies;

refuse to approve a pending marketing application, such as a BLA or supplements to a BLA submitted by us;

seize product; or

refuse to allow us to enter into supply contracts, including government contracts.

39

 
 
 
 
 
 
 
Any government investigation of alleged violations of law could require us to expend significant time and resources in response and

could generate negative publicity. The occurrence of any event or penalty described above may inhibit our ability to commercialize our
product candidates and generate revenues.

Failure to obtain regulatory approval in international jurisdictions would prevent our product candidates from being marketed

abroad.

In addition to regulations in the United States, to market and sell our products in the European Union, many Asian countries and
other jurisdictions, we must obtain separate regulatory approvals and comply with numerous and varying regulatory requirements. The
approval procedure varies among countries and can involve additional testing. The time required to obtain approval may differ
substantially from that required to obtain FDA approval. The regulatory approval process outside the United States generally includes all of
the risks associated with obtaining FDA approval. Clinical trials accepted in one country may not be accepted by regulatory authorities in
other countries. In addition, many countries outside the United States require that a product be approved for reimbursement before it can be
approved for sale in that country. A product candidate that has been approved for sale in a particular country may not receive
reimbursement approval in that country. We may not be able to obtain approvals from regulatory authorities outside the United States on a
timely basis, if at all. Approval by the FDA does not ensure approval by regulatory authorities in other countries or jurisdictions, and
approval by one regulatory authority outside the United States does not ensure approval by regulatory authorities in other countries or
jurisdictions or by the FDA. We may not be able to file for regulatory approvals and may not receive necessary approvals to commercialize
our products in any market. If we are unable to obtain approval of any of our product candidates by regulatory authorities in the European
Union, Asia or elsewhere, the commercial prospects of that product candidate may be significantly diminished, our business prospects
could decline and this could materially adversely affect our business, results of operations and financial condition.

Our relationships with customers and third-party payors will be subject to applicable anti-kickback, fraud and abuse and other

healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm
and diminished profits and future earnings.

Healthcare providers, physicians and third-party payors will play a primary role in the recommendation and prescription of any
product candidates for which we obtain regulatory approval. Our current and future arrangements with healthcare providers, third-party
payors and customers may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the
business or financial arrangements and relationships through which we would market, sell and distribute our products. As a pharmaceutical
company, even though we do not and will not control referrals of healthcare services or bill directly to Medicare, Medicaid or other third-
party payors, federal and state healthcare laws and regulations pertaining to fraud and abuse and patients’ rights are and will be applicable to
our business. Restrictions under applicable federal and state healthcare laws and regulations that may affect our ability to operate include
the following:

•

•

•

•

•

the federal healthcare Anti-Kickback Statute will constrain our marketing practices, educational programs, pricing policies,
and relationships with healthcare providers or other entities, by prohibiting, among other things, persons from knowingly
and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, overtly or covertly, 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 a federal healthcare program such as Medicare and
Medicaid;

federal civil and criminal false claims laws and civil monetary penalty laws impose criminal and civil penalties, including
through 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 or approval 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, imposes criminal and civil liability for
executing a scheme to defraud any healthcare benefit program and also created federal criminal laws that prohibit knowingly
and willfully falsifying, concealing or covering up a material fact or making any materially false statements in connection
with the delivery of or payment for healthcare benefits, items or services;

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, also
imposes obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security and
transmission of individually identifiable health information held by certain healthcare providers, health plans and healthcare
clearinghouses and their business associates;

the federal Physician Payments Sunshine Act created under the Affordable Care Act requires certain manufacturers of
drugs, devices, biologics and medical supplies to report annually to the Centers for Medicare & Medicaid Services, or

40

 
 
 
 
 
CMS, information related to payments and other transfers of value to physicians, other healthcare providers, and teaching
hospitals, and ownership and investment interests held by physicians and other healthcare providers and their immediate
family members and applicable group purchasing organizations;

•

•

analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, may apply to sales or
marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party
payors, including private insurers; some state laws require pharmaceutical companies to comply with the pharmaceutical
industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government
and may 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 govern the privacy and security of health information in specified circumstances, many of which
differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will

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, damages, fines, personal imprisonment, exclusion from government funded
healthcare programs, such as Medicare and Medicaid, additional reporting requirements and oversight if become subject to a corporate
integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and the curtailment or restructuring of
our operations. If any physicians or other healthcare providers or entities with whom we expect to do business are found to not be in
compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government
funded healthcare programs.

Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and

requirements, which could cause significant liability for us and harm our reputation.

We are exposed to the risk of employee fraud or other misconduct, including intentional failures to comply with FDA regulations or
similar regulations of comparable foreign regulatory authorities, provide accurate information to the FDA or comparable foreign regulatory
authorities, comply with manufacturing standards we have established, comply with federal and state healthcare fraud and abuse laws and
regulations and similar laws and regulations established and enforced by comparable foreign regulatory authorities, report financial
information or data accurately or disclose unauthorized activities to us. 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. It is not
always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be
effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or
lawsuits stemming from a failure to 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.

Product liability lawsuits against us could cause us to incur substantial liabilities and to limit commercialization of any products

that we may develop.

We face an inherent risk of product liability exposure related to the testing of our product candidates in human clinical trials and will
face an even greater risk if we commercially sell any products that we may develop. Product liability claims may be brought against us by
subjects enrolled in our clinical trials, patients, healthcare providers or others using, administering or selling our products. If we cannot
successfully defend ourselves against claims that our product candidates or products caused injuries, we could incur substantial liabilities.
Regardless of merit or eventual outcome, liability claims may result in:

•

•

•

•

•

•

•

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

termination of clinical trial sites or entire trial programs;

injury to our reputation and significant negative media attention;

withdrawal of clinical trial participants;

significant costs to defend the related litigation;

substantial monetary awards to trial subjects or patients;

loss of revenue;

41

 
 
 
 
 
 
 
 
 
 
•

•

diversion of management and scientific resources from our business operations; and

the inability to commercialize any products that we may develop.

We currently hold product liability insurance coverage at a level that we believe is customary for similarly situated companies and

adequate to provide us with insurance coverage for foreseeable risks, but which may not be adequate to cover all liabilities that we may
incur. Insurance coverage is increasingly expensive. We may not be able to maintain insurance coverage at a reasonable cost or in an
amount adequate to satisfy any liability that may arise. We intend to expand our insurance coverage for products to include the sale of
commercial products if we obtain regulatory approval for our product candidates in development, but we may be unable to obtain
commercially reasonable product liability insurance for any products that receive regulatory approval. 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, particularly if judgments exceed our insurance coverage, could decrease our cash and adversely affect our business.

We currently rely on third parties to conduct some or all aspects of manufacturing of our product candidates for preclinical and
clinical development.   If one of our third-party manufacturers fails to perform adequately or fulfill our needs, we may be required to
incur significant costs and devote significant efforts, to find new suppliers or manufacturers.

We currently have limited experience in, and we do not own facilities for, clinical-scale manufacturing of our product candidates and

we rely upon third-party contract manufacturing organizations to manufacture and supply drug product for our preclinical and clinical
studies.  The manufacture of pharmaceutical products in compliance with the FDA’s current good manufacturing practices, or cGMP,
requires significant expertise and capital investment, including the development of advanced manufacturing techniques and process
controls. Manufacturers of pharmaceutical products often encounter difficulties in production, including difficulties with production costs
and yields, quality control, including stability of the product candidate and quality assurance testing, shortages of qualified personnel, as
well as compliance with strictly enforced cGMP requirements, other federal and state regulatory requirements and foreign regulations. If
our manufacturers were to encounter any of these difficulties or otherwise fail to comply with their obligations to us or under applicable
regulations, our ability to provide study drugs in our clinical studies would be jeopardized. Any delay or interruption in the supply of
clinical study materials could delay the completion of our clinical studies, increase the costs associated with maintaining our clinical study
programs and, depending upon the period of delay, require us to commence new studies at significant additional expense or terminate the
studies completely.

All manufacturers of our product candidates must comply with cGMP requirements enforced by the FDA through its facilities
inspection program. These requirements include, among other things, quality control, quality assurance and the maintenance of records and
documentation. Manufacturers of our product candidates may be unable to comply with these cGMP requirements and with other FDA,
state and foreign regulatory requirements. The FDA or similar foreign regulatory agencies may also implement new standards at any time,
or change their interpretation and enforcement of existing standards for manufacture, packaging or testing of products. We have limited
control over our manufacturers’ compliance with these regulations and standards. Failure to comply with these requirements 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. If the safety of any product supplied is compromised due to our manufacturers’ failure to adhere to applicable laws or for
other reasons, we may not be able to obtain regulatory approval for or successfully commercialize our products and we may be held liable
for any injuries sustained as a result. Any of these factors could cause a delay of clinical studies, regulatory submissions, approvals or
commercialization of our product candidates, entail higher costs or impair our reputation.

Our current agreements with our suppliers do not provide for the entire supply of the drug product necessary for all anticipated
clinical studies or for full scale commercialization. If we and our suppliers cannot agree to the terms and conditions for them to provide the
drug product necessary for our clinical and commercial supply needs, we may not be able to manufacture the product candidate until a
qualified alternative supplier is identified, which could also delay the development of, and impair our ability to commercialize, our product
candidates.

The number of third-party suppliers with the necessary manufacturing and regulatory expertise and facilities is limited, and it could
be expensive and take a significant amount of time to arrange for alternative suppliers, which could have a material adverse effect on our
business. New suppliers of any product candidate would be required to qualify under applicable regulatory requirements and would need to
have sufficient rights under applicable intellectual property laws to the method of manufacturing the product candidate. Obtaining the
necessary FDA approvals or other qualifications under applicable regulatory requirements and ensuring non-infringement of third-party
intellectual property rights could result in a significant interruption of supply and could require the new manufacturer to bear significant
additional costs which may be passed on to us.

42

 
 
There are risks associated with manufacturing for clinical and commercial use. Manufacturing biological components at the

appropriate scale and quality is complex and difficult. 

There are risks associated with manufacturing our products including, among others, GMP compliance, cost overruns, technical

problems with process scale-up, process reproducibility, stability issues, lot consistency and timely availability of raw materials. Even if
efficacy and safety data from our clinical trials would otherwise support regulatory approval for a product candidate, there is no assurance
that we or any third-party manufacturer will be able to manufacture our product candidates to specifications at levels necessary to support
or maintain commercial approval by the FDA or other regulatory authorities. In addition, we may not be able to manufacture our product
candidates in sufficient quantities to meet the requirements for a potential launch or to meet potential future demand. If we or our third-
party manufacturers are unable to produce sufficient quantities of the approved product for commercialization, either on a timely basis or at
all, our commercialization efforts would be impaired, which would have a material adverse effect on our business, financial condition,
results of operations and growth prospects.

We face uncertainties and risks associated with the manufacture of our pipeline product candidates. Our product candidates are

biologics and their manufacture involves complex processes, including the development of cell lines or cell systems to produce the
biologic, with the challenge of significant variability. Further, there are difficulties in growing large quantities of such cells and harvesting
and purifying the biologic produced by them. The cost to manufacture biologics is generally far higher than traditional small molecule
chemical compounds, and the manufacturing process can be difficult to reproduce. There is no guarantee we will be successful in
establishing a larger-scale commercial manufacturing process for our pipeline product candidates or obtaining the needed manufacturing
capacity. Due to the high cost to manufacture, inherent uncertainty related to manufacturing costs, and uncertainty in our patient population,
there is risk that some of our product candidates may not be commercially viable.

We do not currently have the infrastructure or capability to manufacture, market and sell therapeutic products on a commercial

scale.

In order for us to commercialize our therapeutic products directly, we would need to develop, or obtain through outsourcing
arrangements, the capability to manufacture, market and sell our products on a commercial scale. Currently, we do not have the ability nor
the financial resources to establish the infrastructure and organizations needed to execute these functions, including such infrastructure
needed for the commercialization of any product from our therapeutic program, which can be complex and costly. If we are unable to
establish adequate manufacturing, sales, marketing and distribution capabilities, we will not be able to directly commercialize our
therapeutics products, which would limit our future growth.

If we are unable to establish sales and marketing capabilities or enter into agreements with third parties to market and sell our

product candidates, we may be unable to generate any revenue.

We do not currently have an organization for the sale, marketing and distribution of pharmaceutical products and the cost of
establishing and maintaining such an organization may exceed the cost-effectiveness of doing so. In order to market any products that may
be approved by the FDA and comparable foreign regulatory authorities, we must build our sales, marketing, managerial and other non-
technical capabilities or make arrangements with third parties to perform these services. There are significant risks involved in building and
managing a sales organization, including our ability to hire, retain and incentivize qualified individuals, generate sufficient sales leads,
provide adequate training to sales and marketing personnel and effectively manage a geographically dispersed sales and marketing team.
Any failure or delay in the development of our internal sales, marketing and distribution capabilities would adversely impact the
commercialization of these products. If we are unable to establish adequate sales, marketing and distribution capabilities, whether
independently or with third parties, we may not be able to generate product revenues and may not become profitable. We will be competing
with many companies that currently have extensive and well-funded sales and marketing operations. Without an internal commercial
organization or the support of a third party to perform sales and marketing functions, we may be unable to compete successfully against
these more established companies. If we are not successful in commercializing our current or future product candidates either on our own
or through collaborations with one or more third parties, our future product revenue will suffer and we would incur significant additional
losses.

We will need to grow the size of our organization, and we may experience difficulties in managing this growth.

As of February 15, 2018, we had 182 full-time employees. We need to grow the size of our organization in order to support our
continued development and potential commercialization of our product candidates. In particular, we will need to add substantial numbers of
additional personnel and other resources to support our development and potential commercialization of our product candidates. As our
development and commercialization plans and strategies continue to develop, or as a result of any future acquisitions, our need for
additional managerial, operational, manufacturing, sales, marketing, financial and other resources will

43

increase. Our management, personnel and systems currently in place may not be adequate to support this future growth. Future growth
would impose significant added responsibilities on members of management, including:

• managing our preclinical studies and clinical trials effectively;

•

identifying, recruiting, maintaining, motivating and integrating additional employees;

• managing our internal development efforts effectively while complying with our contractual obligations to licensors,

licensees, contractors and other third parties;

•

•

improving our managerial, development, operational, information technology, and finance systems; and

expanding our facilities.

As our operations expand, we will also need to manage additional relationships with various strategic partners, suppliers and other

third parties. Our future financial performance and our ability to commercialize our product candidates and to compete effectively will
depend, in part, on our ability to manage any future growth effectively. To that end, we must be able to manage our development efforts and
preclinical studies and clinical trials effectively and hire, train and integrate additional management, research and development,
manufacturing, administrative and sales and marketing personnel. Our failure to accomplish any of these tasks could prevent us from
successfully growing our company

Risks Relating to our Industry

If our competitors develop, acquire, or market technologies or products that are more effective than ours, this would reduce or

eliminate our commercial opportunity.

Any products that we or our collaborators or strategic partners develop by using our ZFP technology platform will enter into highly

competitive markets. Even if we are able to generate products that are safe and effective for their intended use, competing technologies
may prove to be more effective or less expensive, which, to the extent these competing technologies achieve market acceptance, will limit
our revenue opportunities. In some cases, competing technologies have proven to be effective and less expensive. Competing technologies
may include other methods of regulating gene expression or modifying genes. ZFNs and ZFP TFs have broad application in the life
sciences industry and compete with a broad array of new technologies and approaches being applied to genetic research by many
companies. Competing proprietary technologies with our product development focus include but are not limited to:

•

For genome editing and gene therapy products:

•

•

•

•

•

recombinant proteins;

other gene therapy/cDNAs;

antisense;

siRNA and microRNA approaches, exon skipping;

small molecule drugs;

• monoclonal antibodies;

•

•

CRISPR/Cas technology; and

TALE proteins, meganucleases, and MegaTALs.

•

Our Non-Therapeutic Applications compete against similar technologies:

In addition to possessing competing technologies, our competitors include pharmaceutical and biotechnology companies with:

•

•

•

substantially greater capital resources than ours;

larger research and development staffs and facilities than ours; and

greater experience in product development and in obtaining regulatory approvals and patent protection.

44

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
These organizations also compete with us to:

•

•

•

attract qualified personnel;

attract parties for acquisitions, joint ventures or other collaborations; and

license the proprietary technologies of academic and research institutions that are competitive with our technology, which may
preclude us from pursuing similar opportunities.

Accordingly, our competitors may succeed in obtaining patent protection or commercializing products before us. In addition, any

products that we develop may compete with existing products or services that are well established in the marketplace.

Our product candidates are based on a novel technology, which makes it difficult to predict the timing and costs of development

and of subsequently obtaining regulatory approval.

We have concentrated our research and development efforts on genome editing, gene therapy, gene regulation and cell therapy. The
regulatory approval process for novel product candidates such as ours is unclear and may be lengthier and more expensive than the process
for other, better-known or more extensively studied product candidates.

Adverse developments in clinical trials of gene therapy products conducted by others may cause the FDA or other oversight bodies to

change the requirements for approval of our product candidates.

These regulatory review committees and advisory groups, and any new guidelines they promulgate, may lengthen the regulatory
review process, require us to perform additional preclinical studies or clinical trials, increase our development costs, lead to changes in
regulatory positions and interpretations, delay or prevent approval and commercialization of our current or future product candidates or lead
to significant post-approval limitations or restrictions. As we advance our product candidates, we will be required to consult with these
regulatory and advisory groups and comply with applicable guidelines. If we fail to do so, we may be required to delay or discontinue
development of our product candidates. These additional processes may result in a review and approval process that is longer than we
otherwise would have expected. Delay or failure to obtain, or unexpected costs in obtaining, the regulatory approval necessary to bring a
potential product to market could decrease our ability to generate sufficient product revenue, and our business, financial condition, results
of operations and prospects would be harmed. Even if our product candidates are approved, we expect that the FDA will require us to
submit follow-up data regarding our clinical trial subjects for a number of years after approval. If this follow-up data shows negative long-
term safety or efficacy outcomes for these patients, the FDA may revoke its approval or change the label of our products in a manner that
could have an adverse impact on our business.

In addition, adverse developments in clinical trials of gene therapy products conducted by others may cause the FDA or other

oversight bodies to change the requirements for approval of our product candidates.  FDA only recently approved the first vector-based
gene therapy, LUCTURNA, and only two gene therapy products, uniQure N.V.’s Glybera and GlaxoSmithKline’s Strimvelis, have
received marketing authorization from the EMA. As a result, it is difficult to determine how long it will take or how much it will cost to
obtain regulatory approvals for our product candidates.

Our gene therapy approach utilizes vectors derived from viruses, which may be perceived as unsafe or may result in unforeseen
adverse events. Negative public opinion and increased regulatory scrutiny of gene therapy may damage public perception of the safety
of our product candidates and adversely affect our ability to conduct our business or obtain regulatory approvals for our product
candidates.

Gene therapy remains a novel technology, with only one vector-based gene therapy product approved for a genetic disease to date in
the United States and only two gene therapy products for genetic diseases approved to date in the European Union. Public perception may
be influenced by claims that gene therapy is unsafe, and gene therapy may not gain the acceptance of the public or the medical community.
In particular, our success will depend upon physicians who specialize in the treatment of genetic diseases targeted by our product
candidates, prescribing treatments that involve the use of our product candidates in lieu of, or in addition to, existing treatments with which
they are familiar and for which greater clinical data may be available. More restrictive government regulations or negative public opinion
would have an adverse effect on our business, financial condition, results of operations and prospects and may delay or impair the
development and commercialization of our product candidates or demand for any products we may develop. For example, earlier gene
therapy trials led to several well-publicized adverse events, including cases of leukemia and death seen in other trials using other vectors.
Serious adverse events in our clinical trials, or other clinical trials involving gene therapy products or our competitors’ products, even if not
ultimately attributable to the relevant product candidates, and the resulting publicity, could result in increased government regulation,
unfavorable public perception, potential regulatory delays in the testing or approval

45

 
 
 
of our product candidates, stricter labeling requirements for those product candidates that are approved and a d ecrease in demand for any
such product candidates.

Laws or public sentiment may limit the production of genetically modified agricultural products, and these laws could reduce our

partner’s ability to sell such products.

Genetically modified products are currently subject to public debate and heightened regulatory scrutiny, either of which could prevent
or delay production of agricultural products. We have exclusive right to use our ZFP technology to modify the genomes or alter the nucleic
acid or protein expression of plant cells, plants or plant cell cultures. The field-testing, production and marketing of genetically modified
plants and plant products are subject to federal, state, local and foreign governmental regulation. Regulatory agencies administering existing
or future regulations or legislation may not allow production and marketing of our genetically modified products in a timely manner or
under technically or commercially feasible conditions. In addition, regulatory action or private litigation could result in expenses, delays or
other impediments to our product development programs or the commercialization of resulting products.

The FDA currently applies the same regulatory standards to foods developed through genetic engineering as those applied to foods

developed through traditional plant breeding. Genetically engineered food products, however, will be subject to pre-market review if these
products raise safety questions or are deemed to be food additives. Governmental authorities could also, for social or other purposes, limit
the use of genetically modified products created with our gene regulation technology.

Even if the regulatory approval for genetically modified products developed using our ZFP technology is obtained, our success will

also depend on public acceptance of the use of genetically modified products including drugs, plants, and plant products. Claims that
genetically modified products are unsafe for consumption or pose a danger to the environment may influence public attitudes. Our
genetically modified products may not gain public acceptance. The subject of genetically modified organisms has received negative
publicity in the United States and particularly in Europe, and such publicity has aroused public debate. The adverse publicity in Europe
could lead to greater regulation and trade restrictions on imports of genetically altered products. Similar adverse public reaction or
sentiment in the United States to genetic research and its resulting products could result in greater domestic regulation and could decrease
the demand for our technology and products.

Risks Relating to our Finances

We have incurred significant operating losses since inception and anticipate that we will incur continued losses for the

foreseeable future.

We have generated operating losses since we began operations in 1995. Our net losses for the years ended December 31, 2017, 2016

and 2015 were $54.6 million, $71.7 million and $40.7 million, respectively. The extent of our future losses and the timing of profitability
are uncertain, and we expect to incur losses for the foreseeable future. We have been engaged in developing our ZFP technology since
inception, which has and will continue to require significant research and development expenditures. To date, we have generated our
funding from issuance of equity securities, revenues derived from collaboration agreements, other strategic partnerships in non-therapeutic
applications of our technology, federal government research grants and grants awarded by research foundations. As of December 31, 2017,
we had an accumulated deficit of $495.5 million. Since our initial public offering in 2000, we have generated an aggregate of
approximately $418.6 million in gross proceeds from the sale of our equity securities. We expect to continue to incur additional operating
losses for the next several years as we continue to advance our product candidates. If the time required to generate significant product
revenues and achieve profitability is longer than we currently anticipate or if we are unable to generate liquidity through equity financing or
other sources of funding, we may be forced to curtail or suspend our operations.

We may be unable to raise additional capital, which would harm our ability to develop our technology and products.

We have incurred significant operating losses and negative operating cash flows since inception and have not achieved profitability.
We expect capital outlays and operating expenditures to increase over the next several years as we expand our infrastructure and research
and product development activities. While we believe our financial resources will be adequate to sustain our current operations for at least
the next twelve months, we will likely seek additional sources of capital through equity or debt financing. In addition, as we focus our
efforts on proprietary human therapeutics, we will need to seek FDA approval of potential products, a process that could cost in excess of
hundreds of millions of dollars per product. Furthermore, we may experience difficulties in accessing the capital market due to external
factors beyond our control such as volatility in the equity markets for emerging biotechnology companies and general economic and market
conditions both in the United States and abroad. We cannot be certain that we will be able to obtain financing on terms acceptable to us, or
at all. Our failure to obtain adequate and timely funding will materially adversely affect our business and our ability to develop our
technology and products candidates. Furthermore, any sales

46

of additional equity securities may result in dilution to our stockholders and any debt financing may include business and financial
covenants that restricts our operations.

We are at the development phase of operations and may not succeed or become profitable.

We began operations in 1995, are in the early phases of product development for the most advanced candidates in our therapeutics

pipeline, and we have incurred significant losses since inception. To date, our revenues have been generated from collaboration
agreements, other collaborations in non-therapeutic applications of our technology, federal government research grants and grants awarded
by research foundations. Our focus on higher-value therapeutic product development and related collaboration requires us to incur
substantial expenses associated with product development. In addition, the preclinical or clinical failure of any single product may have a
significant effect on the actual or perceived value of our stock. Our business is subject to all of the risks inherent in the development of a
new technology, which includes the need to:

•

•

•

•

attract and retain qualified scientific and technical staff and management, particularly scientific staff with expertise to develop
our early-stage technology into therapeutic products;

obtain sufficient capital to support the expense of developing our technology platform and developing, testing and
commercializing products;

develop a market for our products; and

successfully transition from a company with a research focus to a company capable of supporting commercial activities.

The recently passed comprehensive tax reform bill could adversely affect our business and financial condition.

On December 22, 2017, President Trump signed into law new legislation that significantly revises the Internal Revenue Code of
1986, as amended (the Code). The newly enacted federal income tax law, among other things, contains significant changes to corporate
taxation, including adoption of a flat 21% corporate tax rate, limitation of the tax deduction for interest expense to 30% of adjusted
earnings (except for certain small businesses), limitation of the deduction of net operating losses generated in tax years beginning after
December 31, 2017 to 80% of current year taxable income and elimination of carrybacks of such net operating losses, one time taxation of
offshore earnings at reduced rates regardless of whether they are repatriated, current inclusion in U.S. federal taxable income of certain
earnings of controlled foreign corporations, immediate deductions for certain new investments instead of deductions for depreciation
expense over time, and modifying or repealing many business deductions and credits (including reducing the business tax credit for certain
clinical testing expenses incurred in the testing of certain drugs for rare diseases or conditions generally referred to as “orphan drugs”).
Notwithstanding the reduction in the corporate income tax rate, the overall impact of the new federal tax law is uncertain, and our business
and financial condition could be adversely affected. In addition, it is uncertain if and to what extent various states will conform to the newly
enacted federal tax law. The impact of this tax reform on holders of our common stock is also uncertain and could be adverse. Investors
should consult with their legal and tax advisors with respect to this legislation and the potential tax consequences of investing in or holding
our common stock.

Risks Relating to our Relationships with Collaborators and Strategic Partners

If conflicts arise between us and our collaborators or strategic partners, these parties may act in their self-interest, which may

limit our ability to implement our strategies.

If conflicts arise between our corporate or academic collaborators or strategic partners and us, the other party may act in its self-
interest, which may limit our ability to implement our strategies. Some of our academic collaborators and strategic partners are conducting
multiple product development efforts within each area that is the subject of the collaboration with us. Our collaborators or strategic
partners may develop, either alone or with others, products in related fields that are competitive with the products or potential products that
are the subject of these collaborations. Competing products, either developed by the collaborators or strategic partners or to which the
collaborators or strategic partners have rights, may result in the withdrawal of partner support for our product candidates.

Some of our collaborators or strategic partners could also become our competitors in the future. Our collaborators or strategic
partners could develop or invest in competing products, preclude us from entering into collaborations with their competitors, fail to obtain
timely regulatory approvals, terminate their agreements with us prematurely, or fail to devote sufficient resources to the development and
commercialization of products. Any of these developments could harm our product development efforts.

47

 
 
 
 
 
Our collaborators and strategic partners may control aspects of our clinical trials, which could result in delays and other

obstacles in the commercialization of our proposed products.

We depend on third-party collaborators and strategic partners to design and conduct our clinical trials for some of our therapeutic

programs. As a result, we may not be able to conduct these programs in the manner or on the time schedule we currently contemplate,
which may negatively impact our business operations. In addition, if any of these collaborators or strategic partners withdraws support for
our programs or proposed products or otherwise impair their development; our business could be negatively affected.

For example, under our agreements with Kite, Pfizer and Bioverativ, they have control and broad discretion over all or certain
aspects of the clinical development and commercialization of any product developed under the agreement, and we will have little, if any,
influence on how these programs will be conducted. Our lack of control over the clinical development in such agreements could cause
delays or other difficulties in the development and commercialization of our product candidates, which may prevent us from completing
the intended IND filings in a timely fashion and receiving any milestone, royalty payments and other benefits under the agreement. In
addition, under their respective agreements, our third-party collaborators have certain rights to terminate the agreements by providing us
with advance notices, therefore, the actual milestone payments that we may receive under these agreements may be lower than the full
amounts stated above.

Our collaborators or strategic partners may decide to adopt alternative technologies or may be unable to develop commercially

viable products with our technology, which would negatively impact our revenues and our strategy to develop these products.

Our collaborators or strategic partners may adopt alternative technologies, which could decrease the marketability of
ZFP technology. Additionally, because many of our collaborators or strategic partners are likely to be working on more than one
development project, they could choose to shift their resources to projects other than those they are working on with us. If they do so, this
would delay our ability to test our technology and would delay or terminate the development of potential products based on our ZFP
technology. Further, our collaborators and strategic partners may elect not to develop products arising out of our collaborative and strategic
partnering arrangements or to devote sufficient resources to the development, manufacturing, marketing or sale of these products. If they
terminate the collaborative relationship with us, we will be required to seek the support of other partners or collaborators. We may not have
sufficient resources and expertise to develop these programs by ourselves, and we may not be able to identify a suitable partner or negotiate
a favorable collaboration agreement to allow us to continue the development of these programs. If any of these events occur, we may not be
able to develop our technologies or commercialize our products.

If the licensed products under our non-therapeutic license agreements are not successfully commercialized, or our third-party

licensees terminate our agreements, our ability to generate revenue under these license agreements may be limited.

We have a number of collaboration agreements with third parties whereby we licensed our ZFP technologies to develop products in
non- therapeutic fields, such as laboratory research reagents, protein pharmaceuticals, and, transgenic animals, as well as plant agriculture

We cannot be certain that we or our collaboration partners will succeed in the development of commercially viable products in these

non-therapeutic fields of use, and there is no guarantee that we or our collaboration partners will achieve the milestones set forth in the
respective license agreements. To the extent we or our collaboration partners do not succeed in developing and commercializing products or
if we or our collaboration partners fail to achieve such milestones, our revenues and benefits under the license agreements will be limited.
In the event our third party licensees decide to terminate the license agreements, our ability to generate revenue under such license
agreements will cease.

Our collaborations with outside scientists may be subject to change, which could limit our access to their expertise.

We work with scientific advisors and collaborators at academic research institutions. These scientists are not our employees and may

have other commitments that would limit their availability to us. Although our scientific advisors generally agree not to do competing
work, if a conflict of interest between their work for us and their work for another entity arises, we may lose their services. Although our
scientific advisors and academic collaborators sign agreements not to disclose our confidential information, it is possible that some of our
valuable proprietary knowledge may become publicly known through them, which may cause competitive harm to our business.

Risks Relating to our Intellectual Property

Because it is difficult and costly to protect our proprietary rights, and third parties may have filed patent applications that are

similar to ours, we cannot guarantee the proprietary protection of our technologies and products.

Our commercial success will depend in part on obtaining patent protection of our technology and successfully defending any of our

patents that may be challenged. The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and can
involve complex legal and factual questions. No consistent policy regarding the breadth of claims allowed in biotechnology patents has
emerged to date. Accordingly, we cannot predict the breadth of claims allowed in patents we own or license that a third party may receive.

As disclosed herein, we are a party to various license agreements that give us rights under specified patents and patent applications.

Our current licenses, as our future licenses frequently will, contain performance obligations. If we fail to meet those obligations, the
licenses could be terminated. If we are unable to continue to license these technologies on commercially reasonable terms, or at all, we may
be forced to delay or terminate aspects of our product development and research activities.

With respect to our present and any future sublicenses, because our rights derive from those granted to our sublicensor, we are

subject to the risk that our sublicensor may fail to perform its obligations under the master license or fail to inform us of useful
improvements in, or additions to, the underlying intellectual property owned by the original licensor.

We are unable to exercise the same degree of control over intellectual property that we license from third parties as we exercise over

our internally developed intellectual property. We do not control the prosecution of certain of the patent applications that we license from
third parties; therefore, the patent applications may not be prosecuted as we desire or in a timely manner.

The degree of future protection for our proprietary rights is uncertain, and we cannot ensure that:

•

•

•

•

•

•

•

•

we or our licensors were the first to make the inventions covered by each of our pending patent applications;

we or our licensors were the first to file patent applications for these inventions;

the patents of others will not have an adverse effect on our ability to do business;

others will not independently develop similar or alternative technologies or reverse engineer any of our products, processes or
technologies;

any of our pending patent applications will result in issued patents;

any patents issued or licensed to us or our collaborators or strategic partners will provide a basis for commercially viable
products or will provide us with any competitive advantages;

any patents issued or licensed to us will not be challenged and invalidated by third parties; or

we will develop additional products, processes or technologies that are patentable.

Others have filed and in the future are likely to file patent applications that are similar to ours. We are aware that there are academic

groups and other companies that are attempting to develop technology that is based on the use of zinc finger, TALE, CRISPR/Cas and
other DNA-binding proteins, and that these groups and companies have filed patent applications. Several patents have been issued,
although we have no current plans to use the associated inventions. If these or other patents issue, it is possible that the holder of any patent
or patents granted on these applications may bring an infringement action against our collaborators, strategic partners, or us claiming
damages and seeking to enjoin commercial activities relating to the affected products and processes. The costs of litigating the claim could
be substantial. Moreover, we cannot predict whether we, our collaborators, or strategic partners would prevail in any actions. In addition, if
the relevant patent claims were upheld as valid and enforceable and our products or processes were found to infringe the patent or patents,
we or our collaborators could be prevented from making, using, or selling the relevant product or process unless we or our collaborators
could obtain a license or were able to design around the patent claims. We can give no assurance that such a license would be available to
us and our collaborators on commercially reasonable terms, or at all, or that we would be able to successfully design around the relevant
patent claims. There may be significant litigation in the genomics industry regarding patent and other intellectual property rights, which
could subject us to litigation. If we become involved in litigation, it could consume a substantial portion of our managerial and financial
resources.

We rely on trade secrets to protect technology where we believe patent protection is not appropriate or obtainable. Trade secrets,

however, are difficult to protect. While we require employees, academic collaborators and consultants to enter into confidentiality

49

 
 
 
 
 
 
 
 
agreements, we may not be able to adequately protect our trade secrets or other proprietary information or enforce these confidentiality
agreements.

Our collaborators, strategic partners, and scientific advisors have rights to publish data and information in which we may have rights.

If we cannot maintain the confidentiality of our technology and other confidential information in connection with our collaborations and
strategic partnerships, then we may not be able to receive patent protection or protect our proprietary information.

If we are unable to obtain or protect intellectual property rights related to our product candidates, we may not be able to compete

effectively in our markets.

We rely upon a combination of patents, trade secret protection and confidentiality agreements to protect the intellectual property

related to our product candidates. The strength of patents in the biotechnology and pharmaceutical field involves complex legal and
scientific questions and can be uncertain. The patent applications that we own or in-license may fail to result in issued patents with claims
that cover our product candidates in the United States or in other foreign countries. There is no assurance that all of the potentially relevant
prior art relating to our patents and patent applications has been found, which can invalidate a patent or prevent a patent from issuing from a
pending patent application. Even if patents do successfully issue and even if such patents cover our product candidates, third parties may
challenge their validity, enforceability or scope, which may result in such patents being narrowed or invalidated. Furthermore, even if they
are unchallenged, our patents and patent applications may not adequately protect our intellectual property, provide exclusivity for our
product candidates or prevent others from designing around our claims. Any of these outcomes could impair our ability to prevent
competition from third parties, which may have an adverse impact on our business.

If the patent applications we hold or have in-licensed with respect to our programs or product candidates fail to issue, if their breadth or

strength of protection is threatened, or if they fail to provide meaningful exclusivity for our product candidates, it could dissuade
companies from collaborating with us to develop product candidates, and threaten our ability to commercialize, future products. Several
patent applications covering our product candidates have been filed recently. We cannot offer any assurances about which, if any, patents
will issue, the breadth of any such patent or whether any issued patents will be found invalid and unenforceable or will be threatened by
third parties. Any successful opposition to these patents or any other patents owned by or licensed to us could deprive us of rights
necessary for the successful commercialization of any product candidates that we may develop. Further, if we encounter delays in
regulatory approvals, the period of time during which we could market a product candidate under patent protection could be reduced. Since
patent applications in the United States and most other countries are confidential for a period of time after filing, and some remain so until
issued, we cannot be certain that we were the first to file any patent application related to a product candidate. Furthermore, if third parties
have filed such patent applications, an interference proceeding in the United States can be initiated by a third party to determine who was
the first to invent any of the subject matter covered by the patent claims of our applications. In addition, patents have a limited lifespan. In
the United States, the natural expiration of a patent is generally 20 years after it is filed. Various extensions may be available however the
life of a patent, and the protection it affords, is limited. Even if patents covering our product candidates are obtained, once the patent life
has expired for a product, we may be open to competition from generic medications.

In addition to the protection afforded by patents, we rely on trade secret protection and confidentiality agreements to protect

proprietary know-how that is not patentable or that we elect not to patent, processes for which patents are difficult to enforce and any other
elements of our product candidate discovery and development processes that involve proprietary know-how, information or technology that
is not covered by patents. However, trade secrets can be difficult to protect. We seek to protect our proprietary technology and processes, in
part, by entering into confidentiality agreements with our employees, consultants, scientific advisors and contractors. We also seek to
preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security of our premises and physical and
electronic security of our information technology systems. While we have confidence in these individuals, organizations and systems,
agreements or security measures may be breached, and we may not have adequate remedies for any breach. In addition, our trade secrets
may otherwise become known or be independently discovered by competitors.

Although we expect all of our employees and consultants to assign their inventions to us, and all of our employees, consultants,
advisors and any third parties who have access to our proprietary know-how, information or technology to enter into confidentiality
agreements, we cannot provide any assurances that all such agreements have been duly executed or that our trade secrets and other
confidential proprietary information will not be disclosed or that competitors will not otherwise gain access to our trade secrets or
independently develop substantially equivalent information and techniques. Misappropriation or unauthorized disclosure of our trade
secrets could impair our competitive position and may have a material adverse effect on our business. Additionally, if the steps taken to
maintain our trade secrets are deemed inadequate, we may have insufficient recourse against third parties for misappropriating the trade
secret. In addition, others may independently discover our trade secrets and proprietary information. For example, the FDA, as part of its
Transparency Initiative, is currently considering whether to make additional information publicly available on a routine basis, including
information that we may consider to be trade secrets or other proprietary information, and it is not clear at the present time how the FDA’s
disclosure policies may change in the future, if at all.

50

Further, the laws of some foreign countries do not protect proprietary rights to the same extent or in the same manner as the laws of the

United States. As a result, we may encounter significant problems in protecting and defending our intellectual property both in the United
States and abroad. If we are unable to prevent material disclosure of the non-patented intellectual property related to our technologies to
third parties, and there is no guarantee that we will have any such enforceable trade secret protection, we may not be able to establish or
maintain a competitive advantage in our market, which could materially adversely affect our business, results of operations and financial
condition.

Third-party claims of intellectual property infringement may prevent or delay our development and commercialization efforts.
Our commercial success depends in part on our avoiding infringement of the patents and proprietary rights of third parties. There is a

substantial amount of litigation, both within and outside the United States, involving patent and other intellectual property rights in the
biotechnology and pharmaceutical industries, including patent infringement lawsuits, interferences, oppositions, ex parte reexaminations,
post-grant review, and inter partes review proceedings before the U.S. Patent and Trademark Office, or U.S. PTO, and corresponding
foreign patent offices. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in
the fields in which we are pursuing development candidates. As the biotechnology and pharmaceutical industries expand and more patents
are issued, the risk increases that our product candidates may be subject to claims of infringement of the patent rights of third parties.

Third parties may assert that we are employing their proprietary technology without authorization. There may be third-party patents or

patent applications with claims to materials, formulations, methods of manufacture or methods for treatment related to the use or
manufacture of our product candidates. Because patent applications can take many years to issue, there may be currently pending patent
applications which may later result in issued patents that our product candidates may infringe. In addition, third parties may obtain patents
in the future and claim that use of our technologies infringes upon these patents. If any third-party patents were held by a court of
competent jurisdiction to cover the manufacturing process of any of our product candidates, any molecules formed during the
manufacturing process or any final product itself, the holders of any such patents may be able to block our ability to commercialize such
product candidate unless we obtained a license under the applicable patents, or until such patents expire. Similarly, if any third-party
patents were held by a court of competent jurisdiction to cover aspects of our formulations, processes for manufacture or methods of use,
including combination therapy, the holders of any such patents may be able to block our ability to develop and commercialize the
applicable product candidate unless we obtained a license or until such patent expires. In either case, such a license may not be available on
commercially reasonable terms or at all.

Parties making claims against us may obtain injunctive or other equitable relief, which could effectively block our ability to further

develop and commercialize one or more of our product candidates. Defense of these claims, regardless of their merit, would involve
substantial litigation expense and would be a substantial diversion of employee resources from our business. In the event of a successful
claim of infringement against us, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful
infringement, pay royalties, redesign our infringing products or obtain one or more licenses from third parties, which may be impossible or
require substantial time and monetary expenditure.

We may not be successful in obtaining or maintaining necessary rights to gene therapy product components and processes for our

development pipeline through acquisitions and in-licenses.

Presently we have rights to the intellectual property, through licenses from third parties and under patents that we own, to develop our
gene therapy product candidates. Because our programs may involve additional product candidates that may require the use of proprietary
rights held by third parties, the growth of our business will likely depend in part on our ability to acquire, in-license or use these proprietary
rights. In addition, our product candidates may require specific formulations to work effectively and efficiently and these rights may be held
by others. We may be unable to acquire or in-license any compositions, methods of use, processes or other third-party intellectual property
rights from third parties that we identify. The licensing and acquisition of third-party intellectual property rights is a competitive area, and a
number of more established companies are also pursuing strategies to license or acquire third-party intellectual property rights that we may
consider attractive. These established companies may have a competitive advantage over us due to their size, cash resources and greater
clinical development and commercialization capabilities.

For example, we sometimes collaborate with U.S. and foreign academic institutions to accelerate our preclinical research or

development under written agreements with these institutions. Typically, these institutions provide us with an option to negotiate a license
to any of the institution’s rights in technology resulting from the collaboration. Regardless of such right of first negotiation for intellectual
property, we may be unable to negotiate a license within the specified time frame or under terms that are acceptable to us. If we are unable
to do so, the institution may offer the intellectual property rights to other parties, potentially blocking our ability to pursue our program.

In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to

license or acquire third-party intellectual property rights on terms that would allow us to make an appropriate return on our

51

investment. If we are unable to successfully obtain rights to required third-party intellectual property rights, our business, financial
condition and prospects for growth could suffer.

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

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

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

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

•

•

•

•

•

•

the scope of rights granted under the license agreement and other interpretation-related issues;

the extent to which our technology and processes infringe on intellectual property of the licensor that is not subject to the
licensing agreement;

the sublicensing of patent and other rights under our collaborative development relationships;

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

the ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and
us and our partners; and

the priority of invention of patented technology.

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

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

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

consuming and unsuccessful.

Competitors may infringe our patents or the patents of our licensors. To counter infringement or unauthorized use, we may be required

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

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

52

 
 
 
 
 
 
Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk

that some of our confidential information could be compromised by disclosure during this type of litigation. There could also be public
announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive
these results to be negative, it could have a material adverse effect on the price of our common stock.

Patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and

the enforcement or defense of our issued patents.

On September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law. The Leahy-Smith Act

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

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

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

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

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

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee

payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated
for non-compliance with these requirements.

Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or applications will be due to

be paid to the U.S. PTO and various governmental patent agencies outside of the United States in several stages over the lifetime of the
patents and/or applications. We have systems in place to remind us to pay these fees, and we employ an outside firm and rely on our
outside counsel to pay these fees due to non-U.S. patent agencies. The U.S. PTO and various non-U.S. governmental patent agencies require
compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. We
employ professionals to help us comply, and in many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in
accordance with the applicable rules. However, there are situations in which non-compliance can result in abandonment or lapse of the
patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, our
competitors might be able to enter the market and this circumstance would have a material adverse effect on our business.

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

If we or one of our licensing partners initiated legal proceedings against a third party to enforce a patent covering one of our product

candidates, the defendant could counterclaim that the patent covering our product candidate is invalid and/or unenforceable.

53

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

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

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

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

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

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign

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

Risks Relating to our Business Operations

If we use biological and hazardous materials in a manner that causes injury or violates laws, we may be liable for damages.
Our research and development activities involve the controlled use of potentially harmful biological materials as well as hazardous
materials, chemicals, and various radioactive compounds typically employed in molecular and cellular biology. We routinely use cells in
culture and gene delivery vectors, and we employ small amounts of radioisotopes in trace experiments. Although we maintain up-to-date
licensing and training programs, we cannot completely eliminate the risk of accidental contamination or injury from the use, storage,
handling, or disposal of these materials. In the event of contamination or injury, we could be held liable for

54

damages that result, and any liability could exceed our resources. We currently carry insurance covering certain claims arising from our use
of these materials. However, if we are unable to maintain our insurance coverage at a reasonable cost and with adequate coverage, our
insurance may not cover any liability that may arise. We are subject to federal, state, and local laws and regulations governing the use,
storage, handling, and disposal of these materials and specified waste products.

Failure to attract, retain, and motivate skilled personnel and cultivate key academic collaborations will delay our product

development programs and our research and development efforts.

Our success depends on our continued ability to attract, retain, and motivate highly qualified management and scientific personnel

and our ability to develop and maintain important relationships with leading research and academic institutions and scientists. Competition
for skilled and qualified personnel and academic and other research collaborations is intense. If we lose the services of personnel with the
necessary skills, including the members of our senior management team, it could significantly impede the achievement of our research and
development objectives. If we fail to negotiate additional acceptable collaborations with academic and other research institutions and
scientists, or if our existing collaborations are unsuccessful, our development programs may be delayed or may not succeed.

Third parties on which we rely and we may be adversely affected by natural disasters and our business continuity and disaster

recovery plans may not adequately protect us from a serious disaster.

Natural disasters could severely disrupt our operations and have a material adverse effect on our business, financial condition, results

of operations and prospects. If a natural disaster, power outage or other event occurred that prevented us from using all or a significant
portion of our headquarters, that damaged critical infrastructure or that otherwise disrupted operations, it may be difficult or, in certain
cases, impossible for us to continue our business for a substantial period of time. The disaster recovery and business continuity plans we
have in place currently are limited and may not prove adequate in the event of a serious disaster or similar event. We may incur substantial
expenses as a result of the limited nature of our disaster recovery and business continuity plans, which could have a material adverse effect
on our business, financial condition, results of operations and prospects.

Our internal computer systems, or those of our collaborators or other contractors or consultants, may fail or suffer security

breaches, which could result in a material disruption of our product development programs.

Our internal computer systems and those of our current and any future collaborators and other contractors or consultants are
vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical
failures. If such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our development
programs and our business operations, whether due to a loss of our trade secrets or other proprietary information or other similar
disruptions. For example, the loss of clinical trial data from completed or future clinical trials 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
were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we
could incur liability, our competitive position could be harmed and the further development and commercialization of our product
candidates could be delayed.

Risks Relating to our Common Stock and Corporate Organization

Our stock price has been volatile and may continue to be volatile, which could result in substantial losses for investors.

Our stock price has been volatile and may continue to be volatile, which could cause stockholders to incur substantial losses. An
active public market for our common stock may not be sustained, and the market price of our common stock may continue to be highly
volatile. The market price of our common stock has fluctuated significantly in response to various factors, some of which are beyond our
control, including but not limited to the following:

•

•

•

•

•

•

announcements by us or collaborators providing updates on the progress or development status of product candidates;

data from clinical trials;

initiation or termination of clinical trials;

changes in market valuations of similar companies;

overall market and economic conditions, including the equity markets for emerging biotechnology companies;

deviations in our results of operations from the guidance given by us;

55

 
 
 
 
 
 
•

•

•

•

•

•

•

announcements by us or our competitors of new or enha nced products, technologies or services or significant contracts,
acquisitions, strategic relationships, joint ventures or capital commitments;

announcement of changes in business and operations by our collaborators and partners, or changes in our existing collaboration
agreements;

regulatory developments;

changes, by one or more of our security analysts, in recommendations, ratings or coverage of our stock.

additions or departures of key personnel;

future sales of our common stock or other securities by us, management or directors, liquidation of institutional funds that
comprised large holdings of our stock; and

decreases in our cash balances.

Actual or potential sales of our common stock by our employees, including our executive officers, pursuant to pre-arranged stock

trading plans could cause our stock price to fall or prevent it from increasing for numerous reasons, and actual or potential sales by
such persons could be viewed negatively by other investors.

In accordance with the guidelines specified under Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, and our policies
regarding stock transactions, a number of our employees, including executive officers and members of our board of directors, have adopted
and may continue to adopt stock trading plans pursuant to which they have arranged to sell shares of our common stock from time to time in
the future. Generally, sales under such plans by our executive officers and directors require public filings. Actual or potential sales of our
common stock by such persons could cause the price of our common stock to fall or prevent it from increasing for numerous reasons.

Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to our equity incentive

plans, could result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to fall.

Additional capital will be needed in the future to continue our planned operations. To the extent we raise additional capital by issuing

equity securities, our stockholders may experience substantial dilution. We may sell common stock, convertible securities or other equity
securities in one or more transactions at prices and in a manner we determine from time to time. If we sell common stock, convertible
securities or other equity securities in more than one transaction, investors may be materially diluted by subsequent sales. These sales may
also result in material dilution to our existing stockholders, and new investors could gain rights superior to our existing stockholders.

Our stock price is also influenced by public perception of gene therapy and government regulation of potential products.

Reports of serious adverse events in a retroviral gene transfer trial for infants with X-linked severe combined immunodeficiency (X-
linked SCID) in France and subsequent FDA actions putting related trials on hold in the United States had a significant negative impact on
the public perception and stock price of certain companies involved in gene therapy. Stock prices of these companies declined whether or
not the specific company was involved with retroviral gene transfer for the treatment of infants with X-linked SCID, or whether the
specific company’s clinical trials were placed on hold in connection with these events. Other potential adverse events in the field of gene
therapy may occur in the future that could result in greater governmental regulation of our potential products and potential regulatory
delays relating to the testing or approval of our potential products. These external events may have a negative impact on public perception
of our business, which could cause our stock price to decline.

We may be subject to claims for rescission and may be subject to other penalties for shares sold under the ATM Agreement.

We are a party to an Amended and Restated At-the-Market Offering Program Sales Agreement, or the ATM Agreement, pursuant to

which we may sell, from time to time, an aggregate of $75 million of our common stock through the investment bank acting as our sales
agent under the ATM Agreement.  The shares under the original At-the-Market Offering Program Sales Agreement entered into with the
sales agent in December 2016 were initially to be sold pursuant to a shelf registration statement on Form S-3 that initially became effective
in February 2014, or the prior registration statement.  In March 2017, we sold an aggregate of $3.8 million of our common stock, and
received net proceeds of $3.4 million, under the ATM Agreement at an average price per share of $4.39, and at the times of those sales, we
believed that the prior registration statement was then effective. However, subsequent to those sales, we were advised that the prior
registration statement had in fact expired prior to the time of the sales in March 2017 ATM sales. Because our registration statement had in
fact expired prior to the time of such sales, we may be deemed to have violated Section 5 of

56

 
 
 
 
 
 
 
the Securities Act, which requires registration of public offerings of securities. Consequently, we may be subject to claims for rescission by
purchasers who purchased shares of our common stock under the ATM Agreement in March 2017.  Under Section 12(a)(1) of the
Securities Act, a purchaser of security in a transaction made in violation of Section 5 of the Securities Act may obtain recovery of the
consideration paid in connection with its purchase, plus statutory interest, or, if it had already sold the shares, recover damages resulting
from its purchase. While we believe it is unlikely that a successful claim will be asserted against us by any purchasers who purchased
shares of our common stock under the ATM Agreement in March 2017, we cannot guarantee that no such legal claims will be asserted
against us by any purchasers. In addition, we could become subject to enforcement actions and/or penalties and fines by federal authorities,
and we are unable to predict the likelihood of any such enforcement actions being brought against us, or the amount of any such potential
penalties or fines.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our

stock price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish

about us or our business. In the event securities or industry analysts who cover us downgrade our stock or publish inaccurate or unfavorable
research about our business, our stock price would likely decline. If one or more of these analysts cease coverage of our company or fail to
publish reports on us regularly, demand for our stock could decrease, which might cause our stock price and trading volume to decline.

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

We have never declared or paid any cash dividends on our common stock. We currently anticipate that we will retain future earnings

for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the
foreseeable future. Any return to stockholders will therefore be limited to the appreciation of their stock.

Anti-takeover provisions in our certificate of incorporation and Delaware law could make an acquisition of our company more

difficult and could prevent attempts by our stockholders to remove or replace current management.

Anti-takeover provisions of Delaware law and in our certificate of incorporation and our bylaws may discourage, delay or prevent a

change in control of our company, even if a change in control would be beneficial to our stockholders. In addition, these provisions may
frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for
stockholders to replace members of our board of directors. In particular, under our certificate of incorporation our board of directors may
issue up to 5,000,000 shares of preferred stock with rights and privileges that might be senior to our common stock, without the consent of
the holders of the common stock. Moreover, without any further vote or action on the part of the stockholders, the board of directors would
have the authority to determine the price, rights, preferences, privileges, and restrictions of the preferred stock. This preferred stock, if it is
ever issued, may have preference over, and harm the rights of, the holders of common stock. Although the issuance of this preferred stock
would provide us with flexibility in connection with possible acquisitions and other corporate purposes, this issuance may make it more
difficult for a third party to acquire a majority of our outstanding voting stock.

Similarly, our authorized but unissued common stock is available for future issuance without stockholder approval. Our certificate of

incorporation further provides that stockholders may not take action by written consent.

In addition, our amended and restated bylaws, as amended:

•

•

establish advance notice requirements for nominations for election to the board of directors or proposing matters that can be
acted upon at stockholders’ meetings; and

prohibit stockholders from calling a special meeting of stockholders.

We are also subject to Section 203 of the Delaware General Corporation Law, which provides, subject to certain exceptions, that if a
person acquires 15% of our voting stock, the person is an “interested stockholder” and may not engage in “business combinations” with us
for a period of three years from the time the person acquired 15% or more or our voting stock.  The application of Section 203 may, in
some circumstances, deter or prevent a change in control of our company even when such change may be beneficial to our stockholders.

57

 
 
Our amended and restated bylaws, as amended, provide that the Court of Chancery of the State of Delaware will be the exclusive

forum for the adjudication of certain disputes, which could limit our stockholders’ ability to obtain a favorable judicial forum for
disputes with us or our directors, officers, or employees.

Our amended and restated bylaws, as amended, provide that the Court of Chancery of the State of Delaware is the sole and exclusive

forum for:

•

•

•

•

any derivative action or proceeding brought on our behalf;

any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of Sangamo to us
or our stockholders;

any action asserting a claim arising pursuant to any provision of the General Corporation Law of the State of Delaware,;
and

any action asserting a claim governed by the internal affairs doctrine.

This provision further provides that any person or entity that acquires any interest in shares of our capital stock will be deemed to

have notice of and consented to the provisions of such provision.

This provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our

directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers, and other employees. If a court
were to find this provision to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving the
dispute in other jurisdictions, which could seriously harm our business.

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

The discussion in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contains trend
analysis, estimates and other forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements include, without limitation, statements
containing the words “believes,” “anticipates,” “expects,” “continue,” and other words of similar import or the negative of those terms or
expressions. Such forward-looking statements are subject to known and unknown risks, uncertainties, estimates and other factors that may
cause the actual results, performance or achievements of the Company, or industry results, to be materially different from any future results,
performance or achievements expressed or implied by such forward-looking statements. Actual results could differ materially from those
set forth in such forward-looking statements as a result of, but not limited to, the “Risk Factors” described in Part I, Item 1A. You should
read the following discussion and analysis along with the “Selected Financial Data” and the financial statements and notes attached to those
statements included elsewhere in this report.

Overview

We are a clinical stage biotechnology company focused on translating ground-breaking science into genomic therapies that transform

patients’ lives using our industry-leading platform technologies in genome editing, gene therapy, gene regulation and cell therapy.

We are a leader in the research and development of zinc finger proteins, or ZFPs, a naturally occurring class of proteins found in

humans. We have used our knowledge and expertise to develop a proprietary technology platform in both genome editing and gene
regulation. ZFPs can be engineered to make zinc finger nucleases, or ZFNs, proteins that can be used to specifically modify DNA
sequences by adding or knocking out specific genes, or genome editing, and ZFP transcription factors or ZFP TFs, proteins that can be
used to increase or decrease gene expression, or gene regulation. In the process of developing this platform, we have accrued significant
scientific, manufacturing and regulatory capabilities and know-how that are generally applicable in the broader field of gene therapy and
have capitalized this knowledge into a conventional gene therapy platform based on adeno-associated viral vector, or AAV, cDNA gene
transfer.

Our strategy is to maximize the value and therapeutic use of our technology platforms. In certain therapeutic areas we intend to
capture the value of our proprietary genome editing and gene therapy products by forward integrating into manufacturing, development and
commercial operations. In other therapeutic areas we intend to partner with biopharmaceutical companies to develop products.

We are focused on the development of human therapeutics for diverse diseases with well-characterized genetic causes. We have

several proprietary clinical and preclinical product candidates in development and have strategically partnered certain programs with
biopharmaceutical companies to obtain funding for our own programs and to expedite clinical and commercial development.

We have an ongoing Phase 1/2 clinical trial evaluating SB-525, a gene therapy for the treatment of hemophilia A, a blood disorder.
We have ongoing Phase 1/2 clinical trials evaluating three product candidates using our proprietary in vivo genome editing approach: SB-
FIX, for the treatment of hemophilia B, a blood disorder, SB-318, for the treatment of Mucopolysaccharidosis Type I, or MPS I, and SB-
913 for the treatment of Mucopolysaccharidosis Type II, or MPS II.  MPS I and MPS II are rare lysosomal storage disorders, or LSDs. We
are also initiating a Phase 1/2 clinical trial evaluating ST-400, developed using our proprietary ZFN-mediated ex vivo cell therapy platform,
for the treatment of beta-thalassemia, a blood disorder. In addition, we have proprietary preclinical and discovery stage programs in other
LSDs and monogenic diseases, including certain central nervous system disorders, cancer immunotherapy, immunology and infectious
disease.

In February 2018, we entered into a global collaboration and license agreement with Kite Pharma, Inc., or Kite, a wholly-owned

subsidiary of Gilead Sciences, Inc., or Gilead, for the research, development and commercialization of potential engineered cell therapies
for cancer. In this collaboration, we will work together with Kite on a research program under which we will design ZFNs and AAVs to
disrupt and insert certain genes in T cells and natural killer, or NK, cells, including the insertion of genes that encode chimeric antigen
receptors, or CARs, T-cell receptors, or TCRs and NK-cell receptors, or NKRs, directed to mutually agreed targets. Kite will be responsible
for all clinical development and commercialization of any resulting products.  

In May 2017, we entered into a global collaboration and license agreement with Pfizer Inc., or Pfizer, for the research, development

and commercialization of SB-525, our gene therapy product candidate for hemophilia A, and closely related products. Under this
agreement, we are responsible for conducting the Phase 1/2 clinical trial and certain manufacturing activities for SB-525, while Pfizer is
responsible for subsequent worldwide development, manufacturing, marketing and commercialization of SB-525. We and Pfizer may also
collaborate in the research and development of additional AAV-based gene therapy products for hemophilia A.  

63

In December 2017, we entered into a new research collaboration and license agreement with Pfizer for the development and
commercialization of potential gene therapy products that use ZFP TFs to treat amyotrophic lateral sclerosis, or ALS, and frontotemporal
lobar degeneration, or FTLD, linked to mutations of the C9ORF72 gene. Under this agreement, we are working with Pfizer on a research
program to identify, characterize and preclinically develop ZFP TFs that satisfy pre-agreed criteria. Pfizer is responsible for subsequent
development, manufacturing and commercialization of licensed products.

We have also established a collaborative partnership with Bioverativ, Inc., or Bioverativ, to research, develop and commercialize
therapeutic gene-edited cell therapy products in hemoglobinopathies, including beta-thalassemia and sickle cell disease, or SCD. We expect
to begin enrolling patients in a Phase 1/2 clinical study in the first half of 2018. Bioverativ is responsible for subsequent development,
manufacturing and commercialization of licensed products.

We have incurred net losses since inception and expect to incur losses in the future as we continue our research and development

activities. To date, we have funded our operations primarily through the issuance of equity securities, revenues from corporate
collaborations and research grants.

Our revenues have consisted primarily of revenues from our corporate partners for zinc finger nuclease, or ZFN, and zinc finger

protein transcription factor, or ZFP TF, programs, contractual payments from strategic partners for research services and research
milestones, and research grant funding. We expect revenues will continue to fluctuate from period to period and there can be no assurance
that new collaborations or partner funding will continue beyond their initial terms or that we are able to meet the milestones specified in
these agreements.

We expect to continue to devote substantial resources to research and development in the future and expect research and development

expenses to increase in the next several years if we are successful in advancing our gene therapy and our genome editing programs in the
clinic and if we are able to progress our earlier stage product candidates into clinical trials. Pursuant to the terms of the agreements with
Kite and Bioverativ, certain expenses related to research and development activities will be reimbursed to us. The reimbursement funds to
be received from Kite and Bioverativ will be recognized as revenue as the costs are incurred and collection is reasonably assured.

General and administrative expenses consist primarily of salaries and personnel related expenses for executive, finance and

administrative personnel, stock-based compensation expenses, professional fees, allocated facilities expenses, patent prosecution expenses
and other general corporate expenses. As we continue to advance our product candidates into and through the clinic, we expect the growth
of our business to require increased general administrative expenses.

For the year ended December 31, 2017, we incurred a consolidated net loss of $54.6 million, or $0.70 per share, compared to a
consolidated net loss of $71.7 million, or $1.02 per share, for the same period in 2016. As of December 31, 2017, we had cash, cash
equivalents, marketable securities and interest receivable totaling $244.6 million compared to $142.8 million as of December 31, 2016. As
of December 31, 2017, we had an accumulated deficit of $495.5 million.

Critical Accounting Policies and Estimates

The accompanying discussion and analysis of our financial condition and results of operations are based upon our consolidated
financial statements and the related disclosures, which have been prepared in accordance with accounting principles generally accepted in
the United States. The preparation of these financial statements requires us to make estimates, assumptions and judgments that affect the
reported amounts in our consolidated financial statements and accompanying notes. We base our estimates on historical experience and on
various other assumptions that we believe 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. We believe the following policies to be the most critical to an understanding of
our financial condition and results of operations because they require us to make estimates, assumptions and judgments about matters that
are inherently uncertain.

Revenue Recognition

Revenues from research activities made under strategic partnering agreements and collaborations are recognized as the services are

provided when there is persuasive evidence that an arrangement exists, delivery has occurred, the price is fixed or determinable, and
collectability is reasonably assured. Revenue generated from research and licensing agreements typically includes upfront signing or license
fees, cost reimbursements, research services, minimum sublicense fees, milestone payments and royalties on future licensee’s product sales.

Multiple Element Arrangements prior to the adoption of ASU No. 2009-13, Revenue Recognition – Multiple Deliverable Revenue

Arrangements (ASU 2009-13). For revenue arrangements entered into before January 1, 2011 that include multiple deliverables, the
elements of such agreement were divided into separate units of accounting if the deliverables met certain criteria,

64

including whether the fair value of the d elivered items could be determined and whether there was evidence of fair value of the
undelivered items. In addition, the consideration was allocated among the separate units of accounting based on their fair values, and the
applicable revenue recognition criteria are considered separately for each of the separate units of accounting. Prior to the adoption of ASU
2009-13, we recognized nonrefundable signing, license or non-exclusive option fees as revenue when rights to use the intellectual property
related to the license were delivered and over the period of performance obligations if we had continuing performance obligations. We
estimated the performance period at the inception of the arrangement and reevaluated it each reporting period. Changes to these estimates
were recorded on a prospective basis.

Multiple Element Arrangements after the adoption of ASU 2009-13. ASU 2009-13 amended the accounting standards for certain

multiple element revenue arrangements to:

provide updated guidance on whether multiple elements exist, how the elements in an arrangement should be separated,
and how the arrangement consideration should be allocated to the separate elements;

require an entity to allocate arrangement consideration to each element based on a selling price hierarchy, also called the
relative selling price method, where the selling price for an element is based on vendor-specific objective evidence, or
VSOE, if available; third-party evidence, or TPE, if available and VSOE is not available; or the best estimate of selling
price, or ESP, if neither VSOE nor TPE is available; and

eliminate the use of the residual method and require an entity to allocate arrangement consideration using the selling price
hierarchy.

For revenue agreements with multiple element arrangements, such as license and development agreements, entered into on or after

January 1, 2011, we allocate revenue to each non-contingent element based on the relative selling price of each element. When applying the
relative selling price method, we determine the selling price for each deliverable using VSOE of selling price or TPE of selling price. If
neither exists, we use ESP for that deliverable. Revenue allocated is then recognized when the basic four revenue recognition criteria are
met for each element. The collaboration and license agreements entered into with Shire in 2012, Biogen in 2014, and Pfizer in May and
December of 2017 were evaluated under these accounting standards.

Additionally, we recognize milestone payments, which are subject to substantive contingencies, upon completion of specified
milestones, which represents the culmination of an earnings process, according to contract terms. Fees from licensees upon sublicensing our
technologies by them to third parties (sublicense fees) are recognized as revenue in the period such fees are due. Minimum annual
sublicense fees are also recognized as revenue in the period in which such fees are due. Royalty revenues are generally recognized when
earned and collectability of the related royalty payment is reasonably assured. We recognize cost reimbursement revenue under
collaborative agreements as the related research and development costs for services are rendered. Deferred revenue represents the portion
of research or license payments received which a portion has not been earned.

Our research grants are typically multi-year agreements and provide for the reimbursement of qualified expenses for research and

development as defined under the terms of the grant agreement. Revenue under grant agreements is recognized when the related qualified
research expenses are incurred.

In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2014-09, Revenue

from Contracts with Customers (Topic 606), or ASC 606. This standard outlines a single comprehensive model for entities to use in
accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including
industry-specific guidance. The main principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred
to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 provides
companies with two implementation methods: (i) apply the standard retrospectively to each prior reporting period presented (full
retrospective application); or (ii) apply the standard retrospectively with the cumulative effect of initially applying the standard as an
adjustment to the opening balance of retained earnings of the annual reporting period that includes the date of initial application (modified
retrospective application). This guidance is effective for annual reporting periods beginning after December 15, 2017, including interim
periods within that reporting period. Under ASU 2014-09, an entity recognizes revenue when its customer obtains control of promised
goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services.
To determine revenue recognition for arrangements that an entity determines are within the scope of ASU 2014-09, the entity performs the
following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the
transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as)
the entity satisfies a performance obligation. ASU 2014-09 also impacts certain other areas, such as the accounting for costs to obtain or
fulfill a contract.

The Company will adopt ASC 606 during the first quarter of 2018 and using the modified retrospective method. The Company has

substantially completed its evaluation of the impact of adopting ASC 606 on its contracts with Bioverativ, Shire, DAS, and Sigma (as
defined below). The Company’s performance obligations with respect to Shire, DAS and Sigma were substantially complete at

65

 
 
 
 
 
December 31, 2017 and any future receipts are contingent upon these counterparties achieving specified development, commercial, and/or
sales targets and would be in the form of milestones or royalties, all of which management concluded are constrained at December 31, 2017
as defined under ASC 606. The Company has also performed an assessment of the impact of adopting ASC 606 on its Bioverativ
collaboration arrangement and has preliminarily concluded that the timing of the recognition of up-front payments and research and
development reimbursements will be decelerated under the new guidance while development and commercialization milestones are
constrained at December 31, 2017, as defined under ASC 606. Based on this assessment, management has preliminarily concluded that the
transition adjustment to be recognized on January 1, 2018 will be less than $5.0 million and will result in a decrease to accumulated deficit
and an increase to deferred revenue at that date as a result of decelerating the recognition of amounts related to research and development
reimbursements and up-front payments under ASC 606.

The Company has not completed its assessment of the effect that the adoption of ASC 606 will have on its agreements with Pfizer
that were entered into during 2017. The Company has preliminarily concluded that any potential milestone and royalty payments payable
under these agreements are constrained at December 31, 2017, as defined under ASC 606, and thus will not result in a change upon
adoption of ASC 606 from the accounting for such payments under ASC 605. No revenue or other amounts were recognized in 2017
related to the agreement that was entered into with Pfizer in late December 2017 and, accordingly, management does not expect any
amounts to be recognized as part of the January 2018 transition adjustment related to this agreement. During 2017, the Company
recognized as revenue $17.0 million of the $70.0 million up-front payment received from agreement the Company entered into with Pfizer
in May 2017, the amount and timing of which may change upon adoption of ASC 606.  

The estimated impact from the adoption of ASU 2014-09 represent management’s best estimates at the time of the preparation of this

Annual Report on Form 10-K. The actual, final quantitative effects of the adoption of ASU 2014-09 are subject to change from these
estimates and such change may be significant, pending the completion of our assessment in the first quarter of 2018.

Research and Development Expenses

We recognize research and development expenses as incurred. Research and development expenses consist of direct and research-

related allocated overhead costs such as facilities costs, salaries and related personnel costs, and material and supply costs. In addition,
research and development expenses include costs related to clinical trials, validation of our testing processes and procedures and related
overhead expenses. Research and development costs incurred in connection with collaborator-funded activities are expensed as incurred.
Costs to acquire technologies that are utilized in research and development that have no alternative future use are expensed as incurred.
Expenses resulting from clinical trials are recorded when incurred based in part on factors such as estimates of work performed, patient
enrollment, progress of patient studies and other events. We make good faith estimates that we believe to be accurate, but the actual costs
and timing of clinical trials are highly uncertain, subject to risks and may change depending upon a number of factors, including our
clinical development plan.

Stock-Based Compensation

We measure and recognize compensation expense for all stock-based payment awards made to our employees and directors,
including employee stock options, employee stock purchases related to our Employee Stock Purchase Plan, or ESPP, and restricted stock
units, or RSUs, on estimated fair values. The fair value of stock-based awards is amortized over the vesting period of the award using a
straight-line method over the requisite service period.

To estimate the value of a stock option award and purchases related to ESPP, we use the Black-Scholes option pricing model. This

model requires inputs such as expected life, expected volatility and risk-free interest rate. These inputs are subjective and generally require
significant analysis and judgment to develop. While estimates of expected life and volatility are derived primarily from our historical data,
the risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant commensurate with the expected life assumption.
To estimate the value of RSUs, we use the closing market value of our common stock on the date the award is issued. Further, we account
for forfeitures as they occur under our adoption of ASU 2016-09. If factors change and different assumptions are employed in determining
the fair value of stock-based awards, the stock-based compensation expense recorded in future periods may differ significantly from what
was recorded in the current period.

Total revenues consisted of revenues from collaboration agreements and research grants. We anticipate revenues over the next

several years will be derived primarily from our collaboration agreements with Kite, Pfizer and Bioverativ.

The increase in revenues from collaborations in 2017 compared to 2016 was primarily due to increases of $17.0 million in revenues
related to the hemophilia A Pfizer agreement, $3.4 million from the upfront license payment and research services provided to Bioverativ,
partially offset by decreases of $2.1 million in royalty revenue related to our DAS license, $0.8 million related to research services
provided to Shire, and $0.5 million in Sigma license and royalty fees. During 2017, revenues related to our collaborative agreements with
Pfizer and Bioverativ represented 47% and 34%, respectively, of total revenues.

The decrease in revenues from collaborations in 2016 compared to 2015 was primarily due to decreases of $12.5 million in revenues

related to Shire research services, $5.0 million in revenues related to Bioverativ research services, and $3.6 million in Sigma license and
royalty fees, partially offset by an increase of $2.1 million in royalty revenue related to our DAS license. During 2016, revenues related to
our collaborative agreements with Bioverativ, DAS and Shire represented 46%, 26% and 17%, respectively, of total revenues.

Research grant revenues were $0.6 million, $0.5 million, and $1.7 million in 2017, 2016, and 2015, respectively. There were no
significant changes in grant revenue from 2016 to 2017. The decrease of $1.2 million in 2016 from 2015 was primarily due to the receipt of
funding from a research grant from CIRM for our beta-thalassemia project in 2015.

The increase of $0.1 million in research and development expenses in 2017 was primarily due to increases of $5.5 million in salaries
and benefits, $1.1 million in clinical trial and manufacturing expenses related to our hemophilia B and MPS programs, and $1.1 million in
facility and operating expenses. This was primarily offset by decreases of $3.4 million in preclinical expenses, $2.5 million in lab supply
expenses, $1.4 million in stock-based compensation expense, and $0.3 million in other professional services.

The decrease of $1.6 million in research and development expenses in 2016 was primarily due to decreases of $5.6 million in
research expenses related to our preclinical programs, and $0.7 million in license expense. This was primarily offset by increases of $2.0
million in personnel related expenses, including salaries and stock-based compensation expense due to increased headcount, $1.8 million in
consulting expenses, $0.6 million in facilities expense, and $0.5 million in lab supply expenses, in each case as we prepared to enter the
clinic in 2016.

The increase of $0.9 million in 2017 was primarily due to increases of $1.5 million in legal expenses, $1.5 million in corporate
expenses, including rebranding in connection with our name change, $1.0 million in salaries and benefits, and $1.0 million in facility
expenses. This increase was primarily offset by a decrease of $4.5 million in stock-based compensation expense, as 2016 included
approximately $4.1 million of stock-based compensation expense recognized in connection with the transition of our former chief
executive officer.

The increase of $7.1 million in 2016 was primarily due to an increase of $6.2 million in personnel related expenses, including $4.1
million in stock-based compensation expense and $2.0 million in salaries and benefits associated with the transition of our chief executive
officer in June 2016, and an increase of $1.5 million for professional services, primarily offset by a decrease of $0.6 million in legal
expenses.

Interest and other income, net

Interest and other income, net, was $1.8 million in 2017, $0.9 million in 2016 and $0.4 million in 2015 and primarily consisted of

interest income resulting from our treasury strategy.

Benefit from income taxes

Benefit from income taxes was $0.0 million, $0.0 million, and $5.7 million for 2017, 2016, and 2015, respectively. We recognized an

immaterial amount of income tax expense/benefit during both 2017 and 2016. The income tax benefit in 2015 was primarily due to $5.0
million income tax benefit recognized from a claims settlement with certain institutional investors that were beneficial owners of our
common stock related to the disgorgement of short swing profits pursuant to Section 16 of the Securities Exchange Act of 1934, as
amended.

As of December 31, 2017, we had net operating loss carryforwards for federal and state income tax purposes of approximately

$475.0 million and $142.0 million, respectively. If not utilized, the net federal and state operating loss carryforwards will expire in 2018
and 2017, respectively. We also have federal and state research tax credit carryforwards of $10.8 million and $11.8 million, respectively.
The federal research credits will begin to expire in 2018 while the state research credits have no expiration date. Utilization of our net
operating loss carryforwards and research tax credit carryforwards may be subject to substantial annual limitations due to the ownership
change limitations provided by the Internal Revenue Code and similar state provisions. The annual limitation could result in the expiration
of the net operating loss carryforwards and research tax credit carryforwards before use.  Due to the carryforwards related to the net
operating losses and research and development tax credits, we do not expect to pay any taxes related to income in the near future.

On December 22, 2017, President Trump signed the Tax Cuts and Jobs Act ("Tax Reform") into legislation.  The Tax Reform makes
significant changes to the US corporate income tax law including, but not limited to, (1) reducing the U.S. federal corporate tax rate to 21%
from 35% and (2) requiring a one-time mandatory transition tax on previously deferred foreign earnings of US subsidiaries.  Under ASC
740, the effects of changes in tax rates and laws are recognized in the period in which the new legislation is enacted.  In the case of US
federal income taxes, the enactment date is the date the bill becomes law.    With respect to this legislation, we expect no financial
statement impact due to the Company's valuation allowance.  The Company performed a re-measurement of deferred tax assets and
liabilities as a result of the decrease in the corporate Federal income tax rate from 35% to 21%. In addition to

the reduction of U.S. federal corporate tax rate, the Company has also considered the impact of the foreign transition tax for which it has
estimated that it would not need to accrue any amounts.

In December 2017, the Securities and Exchange Commission staff issued Staff Accounting Bulletin No.118 (SAB 118) to provide
guidance on the application of the Tax Reform when a company does not have the necessary information available, prepared, or analyzed
in reasonable to detail to reflect the effects of the Tax Reform.  SAB 118 provides guidance for companies under the three scenarios (1)
measurement of certain income tax effects is complete, (2) measurement of certain income tax effect can be reasonably estimated, and (3)
measurement of certain income tax effects cannot be reasonably estimated.  Companies are to complete the accounting under ASC 740 in
regards to the Tax Reform within a measurement period that does not extend one year from the date of enactment (i.e., December 22,
2018).  In accordance with SAB 118, companies must reflect the tax effects of the Tax Reform for which the accounting under 740 is
complete. If certain income tax effect can be reasonably estimated, then the companies must report provisional amounts in the reporting
period in which the companies can determine the reasonable estimate during the measurement period.  In the case that certain income tax
effects cannot be reasonably estimated, companies do not have to report effects of the Tax Reform.  However, they should continue to
apply ASC 740 based on the rules before the enactment of the Tax Reform and report any income tax effects in the first reporting period in
which reasonable estimates become available.

We expect the new law to significantly reduce our tax rate in future periods, and our tax footnote reflects the effects of a Federal tax

rate reduction net of our valuation allowance, which resulted in a net overall reduction of $0. 

The final transition impacts of the Tax Act may differ from the above estimate, possibly materially, due to, among other things,
changes in interpretations of the Tax Act, any legislative action to address questions that arise because of the Tax Act, any changes in
accounting standards for income taxes or related interpretations in response to the Tax Act, or any updates or changes to estimates the
company has utilized to calculate the transition impacts, including impacts from changes to current year earnings estimates and foreign
exchange rates of foreign subsidiaries.  In accordance with SAB 118, the Company is allowed a measurement period of up to one year after
the enactment date of the Tax Act to finalize the recording of the related tax impacts.  We currently anticipate finalizing and recording any
resulting adjustments by year ending December 31, 2018.

Liquidity and Capital Resources

Liquidity

Since inception, we have incurred significant net losses and we have funded our operations primarily through the issuance of equity
securities, payments from corporate collaborators and strategic partners and research grants. Our most significant use of capital pertains to
funding our preclinical and clinical research and development programs, as well as salaries and benefits for employees.

As of December 31, 2017, we had cash, cash equivalents, marketable securities and interest receivable totaling $244.6 million
compared to $142.8 million as of December 31, 2016, with the increase primarily attributable to our completion of an underwritten public
offering of our common stock in June 2017, in which 11.5 million shares of our common stock were sold at a public offering price of $7.25
per share. Net proceeds after deducting underwriting discounts and commissions and other estimated offering expenses, were appropriately
$78.1 million. Cash, cash equivalents, and marketable security further increased attributable to $70.0 million for the upfront license and
service fee received from Pfizer pursuant to the hemophilia A Pfizer agreement. Our cash and investment balances are held in a variety of
interest bearing instruments, including obligations of U.S. government agencies, U.S. Treasury debt securities, corporate debt securities and
money market funds. Cash in excess of immediate requirements is invested in accordance with our investment policy with a view toward
capital preservation and liquidity.

On May 26, 2017, we entered into an Amended and Restated At-the-Market Offering Program Sales Agreement with an investment

bank pursuant to which we may issue and sell from time to time shares of our common stock having an aggregate offering price of up to
$75.0 million through the investment bank acting as our sales agent, or the 2017 ATM Agreement. Under the 2017 ATM Agreement, if we
decide to sell shares, we will notify the sales agent, and the sales agent will use its commercially reasonable efforts to sell on our behalf all
of the shares of common stock requested to be sold.  Sales of our common stock, if any, will be made at market prices by any method that is
deemed to be an “at the market offering” as defined in Rule 415 under the Securities Act, as amended, including sales made directly on The
Nasdaq Global Select Market and sales to or through a market maker other than on an exchange. In addition, with our prior written consent,
the sales agent may also sell shares of our common stock in negotiated transactions under the 2017 ATM Agreement. During the three
months ended March 31, 2017, we issued a total of 871,149 shares of its common stock under the original At-the-Market Offering Program
Sales Agreement entered into during December 2016, and received net proceeds of $3.4 million, after deducting offering expenses,
including $0.1 million of commission paid to the sales agent. These shares were inadvertently sold under a registration statement filed with
the SEC that had in fact expired prior to the time the shares were sold and accordingly, these shares are subject to potential rescission rights,
as described in more detail under “Risk Factors”. In addition, if it were determined that we sold unregistered securities, we could be subject
to enforcement actions or

69

penalties and fines by regulatory authorities. We have not sold any common stock under the 2017 ATM Agreement and the full $75.0
million provided for under the 2017 ATM Agreement remained available for sale thereunder at December 31, 2017.

Since the beginning of 2017, we have received significant amounts of capital as upfront payments under the following

collaboration arrangements: $70.0 million received in May 2017 from Pfizer under our hemophilia A agreement; and $12.0 million
received in January 2018 under our ALS/FTLD agreement. In addition, in February 2018, we entered into the Kite collaboration agreement
pursuant to which upon its effectiveness we will be entitled to receive $150.0 million from Kite. The effectiveness of the Kite agreement is
subject to the expiration or termination of all applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended and other customary closing conditions. We anticipate the effectiveness of the Kite agreement to occur in the first half of 2018.
Our collaboration agreements provide for the payment of development, regulatory, and commercial milestones. For more information see
“Business – Collaborations.”

Cash Flow

Operating activities. Net cash provided by (used in) operating activities primarily reflects our net operating losses adjusted for non-
cash items including stock-based compensation expense. Net cash provided by operating activities was $11.2 million in 2017 compared to
net cash used in operating activities of $65.9 million in 2016. The increase in net cash provided by operating activities in 2017 was
primarily due to the increase in deferred revenues related to the $70.0 million upfront payment from the hemophilia A agreement with
Pfizer.

Net cash used in operating activities was $65.9 million in 2016 compared to $33.7 million in 2015. The increase in net cash used in

operating activities in 2016 was primarily due to an increase operating expenses and a decrease in deferred revenues related to the
recognition of the $20.0 million upfront payment from Bioverativ pursuant to the collaboration and license agreement.

Investing activities. Net cash used in investing activities was $80.9 million in 2017. Net cash provided by investing activities was
$18.1 million in 2016 and $77.5 million in 2015. Cash flows from investing activities for all periods was primarily related to purchases,
sales and maturities of marketable securities and also includes deposits on cash related to lease commitments.

Financing activities. Net cash provided by financing activities was $97.5 million in 2017, $0.3 million in 2016, and $19.7 million in

2015. Net cash provided by financing activities in 2017 was primarily attributable to the completion of an underwritten public offering of
our common stock of $78.1 million, net of issuance costs, and $16.6 million in proceeds from the exercise of stock options. Net cash
provided by financing activities in 2016 was primarily attributable to $1.1 million proceeds from the exercise of stock options, primarily
offset by $0.8 million in taxes paid related to net share settlement of equity awards. Net cash provided by financing activities in 2015 was
primarily attributable to a $14.5 million claim settlement with certain institutional investors that were beneficial owners of our common
stock related to the disgorgement of short-swing profits pursuant to Section 16 of the Securities Exchange Act of 1934, as amended, as well
as proceeds from the exercise of stock options.

Operating Capital and Capital Expenditure Requirements

We anticipate continuing to incur operating losses for at least the next several years. While we expect our rate of cash usage to
increase in the future, in particular to support our product development endeavors, we believe that the available cash resources as well as
funds received from corporate collaborators, strategic partners and research grants will enable us to maintain our currently planned
operations through at least the next twelve months from the date the financial statements are issued. Future capital requirements will be
substantial and if our capital resources are insufficient to meet future capital requirements, we will need to raise additional capital to fund
our operations through equity or debt financing. We regularly consider fund raising opportunities and may decide, from time to time, to
raise capital based on various factors, including market conditions and our plans of operation. Additional capital may not be available on
terms acceptable to us, or at all. If adequate funds are not available, or if the terms of potential funding sources are unfavorable, our
business and our ability to advance our product candidate pipeline would be harmed. Furthermore, any sales of additional equity securities,
including any sales under our ATM Agreement, may result in dilution to our stockholders, and any debt financing may include covenants
that restrict our business.

Our future capital requirements will depend on many forward looking factors, including the following:

•

•

•

•

the initiation, progress, timing and completion of clinical trials for our product candidates and potential product
candidates;

the outcome, timing and cost of regulatory approvals;

the success of our collaboration agreements;

delays that may be caused by changing regulatory requirements;

70

 
 
 
 
•

•

•

•

•

•

•

the number of product candidates that we pursue;

ITEM 7A – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our exposure to market risk relates to our cash, cash equivalents and investments. The goals of our investment policy are preservation

of capital, fulfillment of liquidity needs and capturing a market rate of return based on our investment policy parameters and market
conditions. We select investments that maximize interest income to the extent possible within these guidelines. To achieve our goals, we
maintain a portfolio of cash equivalents and investments in securities of high credit quality and with varying maturities to match projected
cash needs.

The securities in our investment portfolio are not leveraged, are classified as available-for-sale and are, due to their short-term nature,

subject to minimal interest rate risk. Our investments currently consist of U.S. Treasury securities, U.S. government-sponsored enterprise
securities and corporate notes. Our investment policy, approved by our Board of Directors, limits the amount we may invest in any one type
of investment issuer, thereby reducing credit risk concentrations. All investments have a fixed interest rate and are carried at market value,
which approximates cost. We do not use derivative financial instruments in our investment portfolio. We do not believe that a change in
interest rates would have a material negative impact on the value of our investment portfolio.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of Sangamo Therapeutics, Inc.

Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Sangamo Therapeutics, Inc. (the Company) as of December 31, 2017
and 2016, the related consolidated statements of operations, comprehensive loss, stockholders' equity, and cash flows for each of the three
years in the period ended December 31, 2017, and the related notes (collectively referred to as the “consolidated financial statements”). In
our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at
December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December
31, 2017, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the
Company's internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control-Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated
March 1, 2018 expressed an unqualified opinion thereon.

Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the
Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the
Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our
audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud,
and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the
amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant
estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits
provide a reasonable basis for our opinion.

/s/ ERNST & YOUNG LLP

We have served as the Company’s auditor since 1997.

SANGAMO THERAPEUTICS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Overview

Sangamo Therapeutics, Inc. was incorporated in the State of Delaware on June 22, 1995 and changed its name from Sangamo
Biosciences, Inc. in January 2017 (the Company or Sangamo).  Sangamo is focused on the research, development and commercialization of
novel therapeutic strategies for unmet medical needs. Sangamo’s genome editing and gene regulation technology platform is enabled by the
engineering of a class of transcription factors known as zinc finger DNA-binding proteins (ZFPs). Potential applications of Sangamo’s
technology include development of human therapeutics, plant agriculture and enhancement of pharmaceutical protein production. Sangamo
will require additional financial resources to complete the development and commercialization of its products including ZFP Therapeutics.

Sangamo is currently working on a number of long-term development projects that will involve experimental technology. The

projects may require several years and substantial expenditures to complete and ultimately may be unsuccessful. The Company plans to
finance operations with available cash resources, collaborations and strategic partnerships funds, research grants and from the issuance of
equity or debt securities. Sangamo believes that its available cash, cash equivalents and investments as of December 31, 2017, along with
expected revenues from collaborations, strategic partnerships and research grants, will be adequate to fund its operations at least through
the next twelve months from the date the financial statements are issued. Sangamo will need to raise substantial additional capital to fund
subsequent operations and complete the development and commercialization of its products. Additional capital may not be available on
terms acceptable to the Company, or at all. If adequate funds are not available, or if the terms of potential funding sources are unfavorable,
the Company’s business and ability to develop its technology and ZFP Therapeutic products would be harmed. Furthermore, any sales of
additional equity securities may result in dilution to the Company’s stockholders, and any debt financing may include covenants that restrict
the Company’s business.

Basis of Presentation

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make

estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results
could differ from those estimates. The consolidated financial statements include the accounts of Sangamo and its wholly-owned
subsidiaries, Ceregene and Gendaq Limited, after elimination of all intercompany balances and transactions.

Business Combinations

The Company accounts for acquisitions in accordance with Accounting Standards Codification (ASC) Topic 805, Business
Combinations (ASC Topic 805). ASC Topic 805 establishes principles and requirements for recognizing and measuring the total
consideration transferred to and the assets acquired, liabilities assumed and any non-controlling interests in the acquired target in a business
combination. ASC Topic 805 also provides guidance for recognizing and measuring goodwill acquired in a business combination; requires
purchased in-process research and development to be capitalized at fair value as an intangible asset at the time of acquisition; requires
acquisition-related expenses and restructuring costs to be recognized separately from the business combination; expands the definition of
what constitutes a business; and requires the acquirer to disclose information that users may need to evaluate and understand the financial
effect of the business combination.

Cash and Cash Equivalents

Sangamo considers all highly-liquid investments purchased with original maturities of three months or less at the purchase date to be

cash equivalents. Cash and cash equivalents consist of deposits in money market investment accounts.  

Marketable Securities

Sangamo classifies its marketable securities as available-for-sale and records its investments at estimated fair value based on quoted
market prices or observable market inputs of almost identical assets, with the unrealized holding gains and losses included in accumulated
other comprehensive income.

The Company’s investments are subject to a periodic impairment review. The Company recognizes an impairment charge when a

decline in the fair value of its investments below the cost basis is judged to be other-than-temporary. The Company considers various
factors in determining whether to recognize an impairment charge, including the length of time and extent to which the fair

79

 
 
 
 
 
value has been less than the Company’s cost basis, the financial condition and near-term prospects of the investee, and the Company’ s
intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in the market value. Realized
gains and losses on available-for-sale securities are included in other income, which is determined using the specific identification method.

Fair Value Measurements

The carrying amounts for financial instruments consisting of cash and cash equivalents, accounts receivable, accounts payable and

accrued liabilities approximate fair value due to their short maturities. Marketable securities and contingent consideration liabilities are
stated at their estimated fair values. The counterparties to the agreements relating to the Company’s investment securities consist of the US
Treasury, governmental agencies, various major corporations and financial institutions with high credit standing.

Property and Equipment

Property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation is calculated using the

straight-line method based on the estimated useful lives of the related assets (generally three to five years). For leasehold improvements,
amortization is calculated using the straight-line method based on the shorter of the useful life or the lease term. The Company reviews its
property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not
be recoverable.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make
estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. On an ongoing basis,
management evaluates its estimates, including critical accounting policies or estimates related to revenue recognition, clinical trial accruals,
and stock-based compensation. Estimates are based on historical experience and on various other market specific and other relevant
assumptions that the Company believes 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 could differ from those
estimates. During the fourth quarter of 2016, we revised our estimated performance period under the Bioverativ license agreement from
June 2019 to June 2020, which also extended the recognition period of the related up-front payment we received upon entering this
agreement (See Note 5). This change decreased revenues by $4.3 million and increased net loss and net loss per share by $0.06 for the year
ended December 31, 2016.

Revenue Recognition

Revenues from research activities made under strategic partnering agreements and collaborations are recognized as the services are

provided when there is persuasive evidence that an arrangement exists, delivery has occurred, the price is fixed or determinable, and
collectability is reasonably assured. Revenue generated from research and licensing agreements typically includes upfront signing or license
fees, cost reimbursements, research services, minimum sublicense fees, milestone payments and royalties on future licensee’s product sales.

Multiple Element Arrangements prior to the adoption of ASU No. 2009-13, Revenue Recognition—Multiple Deliverable Revenue

Arrangements (ASU 2009-13). For revenue arrangements entered into before January 1, 2011, that include multiple deliverables, the
elements of such agreement were divided into separate units of accounting if the deliverables met certain criteria, including whether the fair
value of the delivered items could be determined and whether there was evidence of fair value of the undelivered items. In addition, the
consideration was allocated among the separate units of accounting based on their fair values, and the applicable revenue recognition
criteria are considered separately for each of the separate units of accounting. Prior to the adoption of ASU 2009-13, the Company
recognized nonrefundable signing, license or non-exclusive option fees as revenue when rights to use the intellectual property related to the
license were delivered and over the period of performance obligations if the Company had continuing performance obligations. The
Company estimated the performance period at the inception of the arrangement and reevaluated it each reporting period. Changes to these
estimates were recorded on a prospective basis.

Multiple Element Arrangements after the adoption of ASU 2009-13. ASU 2009-13 amended the accounting standards for certain

multiple element revenue arrangements to:

•

•

provide updated guidance on whether multiple elements exist, how the elements in an arrangement should be separated,
and how the arrangement consideration should be allocated to the separate elements;

require an entity to allocate arrangement consideration to each element based on a selling price hierarchy where the selling
price for an element is based on vendor-specific objective evidence, or VSOE, if available; third-party evidence,

80

 
 
or TPE, if available and VSOE is not available; or the best estimate of selling price, or ESP, if neither VSOE nor TPE is
available; and

•

eliminate the use of the residual method and require an entity to allocate arrangement consideration using the relative
selling price method.

For revenue agreements with multiple element arrangements, such as license and development agreements, entered into on or after

January 1, 2011, the Company allocates revenue to each non-contingent element based on the relative selling price of each element. When
applying the relative selling price method, the Company determines the selling price for each deliverable using VSOE of selling price or
TPE of selling price. If neither exists the Company uses ESP for that deliverable. Revenue allocated is then recognized when the basic four
revenue recognition criteria are met for each element. The collaboration and license agreements entered into with Shire International
GmbH, formerly Shire AG, or Shire, in January 2012, Biogen MA Inc., or Biogen, in January 2014, and Pfizer Inc., or Pfizer, in May and
December of 2017, were evaluated under these amended accounting standards.

Additionally, the Company may be entitled to receive certain milestone payments which are contingent upon reaching specified

objectives. These milestone payments are recognized as revenue in full upon achievement of the milestone if there is substantive
uncertainty at the date the arrangement is entered into that objectives will be achieved and if the achievement is based on the Company’s
performance.

Minimum annual sublicense fees are also recognized as revenue in the period in which such fees are due. Royalty revenues are

generally recognized when earned and collectability of the related royalty payment is reasonably assured. The Company recognizes cost
reimbursement revenue under collaborative agreements as the related research and development costs for services are rendered. Deferred
revenue represents the portion of research or license payments received but not earned.

Sangamo’s research grants are typically multi-year agreements and provide for the reimbursement of qualified expenses for research

and development as defined under the terms of the grant agreement. Revenue under grant agreements is recognized when the related
qualified research expenses are incurred.

During 2017, revenues related to Pfizer and Bioverativ represented 47% and 34%, respectively, of the Company’s total revenue.

During 2016 revenue related to Bioverativ, DAS and Shire represented 46%, 26%, and 17%, respectively, of total revenue.  During 2015
revenue related to Shire and Biogen represented 40% and 35%, respectively, of total revenues. Receivables from collaborations are
typically unsecured and are concentrated in the biopharmaceutical industry. Accordingly, we may be exposed to credit risk generally
associated with biopharmaceutical companies or specific to our collaboration agreements. To date, we have not experienced any losses
related to these receivables.

Research and Development Expenses

Research and development costs are expensed as incurred. Research and development expenses consist of direct and research-related
allocated overhead costs such as facilities costs, salaries and related personnel costs, and material and supply costs. In addition, research and
development expenses include costs related to clinical trials, validation of the Company’s testing processes and procedures as well as
related overhead expenses. Research and development costs incurred in connection with collaborator-funded activities are expensed as
incurred. Costs to acquire technologies that are utilized in research and development that have no alternative future use are expensed as
incurred.

Stock-Based Compensation

The Company measures and recognizes compensation expense for all stock-based payment awards made to Sangamo employees and

directors, including employee share options, restricted stock units (RSUs) and employee stock purchases related to the Employee Stock
Purchase Plan (ESPP), based on estimated fair values at the award grant date. The fair value of stock-based awards is amortized over the
vesting period of the award using a straight-line method.

To estimate the fair value of an award, the Company uses the Black-Scholes option pricing model. This model requires inputs such

as expected life, expected volatility and risk-free interest rate. These inputs are subjective and generally require significant analysis and
judgment to develop. While estimates of expected life and volatility are derived primarily from the Company’s historical data, the risk-free
rate is based on the U.S. Treasury yield curve in effect at the time of grant commensurate with the expected life assumption. Further, the
Company adopted Accounting Standards Update (ASU) 2016-09 and accounts for forfeitures in the period they occur.

81

 
 
Indefinite-Lived Intangible Assets

As part of the Ceregene acquisition the Company recognized indefinite-lived intangible assets for in-process research and
development and goodwill as further discussed below. ASC 350 and related updates require companies to test indefinite-lived intangible
assets for impairment annually, and more frequently if indicators of impairment exist. ASC 350 includes an optional qualitative assessment
for testing indefinite-lived intangible assets for impairment that permits companies to assess whether it is more likely than not (i.e., a
likelihood of greater than 50%) that an indefinite-lived intangible asset is impaired. If a company concludes based on the qualitative
assessment that it is not more likely than not that the fair value of an indefinite-lived intangible asset or, in the case of goodwill, that the
fair value of the related reporting unit, is less than carrying value, it would not have to determine the asset’s or reporting unit’s fair value,
as applicable.

In-Process Research and Development

Intangible assets related to in-process research and development costs, or IPR&D, are considered to be indefinite-lived until the

completion or abandonment of the associated research and development efforts. If and when development is complete, which generally
occurs if and when regulatory approval to market a product is obtained, the associated assets would be deemed finite-lived and would then
be amortized based on their respective estimated useful lives at that point in time. Prior to completion of the research and development
efforts, the assets are considered indefinite-lived. During this period, the assets will not be amortized but will be tested for impairment on
an annual basis and between annual tests if the Company becomes aware of any events occurring or changes in circumstances that would
indicate a reduction in the fair value of the IPR&D projects below their respective carrying amounts. In the first quarter of 2015, the
Company decided to discontinue the CERE-110 and CERE-120 clinical trial programs. As such, the probability of achieving projected
revenues and cash flows associated with these programs were adversely affected. The Company did not believe the programs have an
alternative future use for itself or other market participants. Accordingly, the Company recognized a $1.9 million impairment charge
related to these assets during the year ended December 31, 2015, which was recognized as research and development (R&D) in the
accompanying consolidated statements of operations.

Goodwill

Goodwill represents the excess of the consideration transferred over the estimated fair values of assets acquired and liabilities
assumed in a business combination and is considered to be indefinite-lived. Goodwill is not amortized but is tested for impairment on an
annual basis and between annual tests if the Company becomes aware of any events occurring or changes in circumstances that would
indicate an impairment of goodwill has occurred. During the fourth quarter of 2017, the Company performed an assessment of the
qualitative factors affecting the fair value of its reporting unit and concluded that it was not more likely than not that the fair value of its
reporting unit was less than carrying value and that, as a result, it is not more likely than not that goodwill is impaired.

Contingent Consideration Liability

Under the merger agreement with Ceregene, the Company is required to make contingent earn-out payments if the Company grants a

third-party license to develop and commercialize certain product candidates acquired from Ceregene, or if the Company commercializes
any of such product candidates itself. These earn-out payments will become payable in the period they are earned. In accordance with ASC
Topic 805, the Company determined the fair value of this liability for contingent consideration on the acquisition date using a probability-
weighted discounted cash flow analysis. During the year ended December 31, 2015, the recognized amount of the liability for contingent
consideration decreased by $1.8 million due to the decrease in the probability of incurring potential future royalty payments associated with
the impairment of IPR&D assets acquired from Ceregene.

Income Taxes

Income tax expense has been provided using the liability method. Deferred tax assets and liabilities are determined based on the

difference between the financial statement and tax bases of assets and liabilities as measured by the enacted tax rates that will be in effect
when these differences reverse. The Company provides a valuation allowance against net deferred tax assets if, based upon the available
evidence, it is not more likely than not that the deferred tax assets will be realized.

Net Loss Per Share

Basic net loss per share has been computed by dividing net loss by the weighted-average number of shares of common stock
outstanding during the period. Diluted net loss per share is calculated by dividing net loss by the weighted average number of shares of
common stock and potential dilutive securities outstanding during the period.

Because Sangamo is in a net loss position, diluted net loss per share excludes the effects of common stock equivalents consisting of

options and restricted stock units, which are all anti-dilutive. All stock options and restricted stock units outstanding

82

were excluded from the calculation of diluted net loss per share for all periods presented. Stock options and restricted stock units
outstanding at the end of 2017, 2016 and 2015 were 8,367,628, 9,578,322, and 9,008,185, respectively.

Segments

The Company operates in one segment. Management uses one measure of profitability and does not segregate its business for internal

reporting. As of December 31, 2017 and 2016, all of the Company’s assets were maintained in the U.S. For the years ended December 31,
2017, 2016 and 2015, substantially all the Company’s revenues and operating expenses were generated and incurred in the U.S.

Recent Accounting Pronouncements

In March 2016 the Financial Accounting Standards Board (FASB) issued ASU 2016-09, Improvements to Employee Share-Based

Payment Accounting (Topic 718). The amendments in ASU 2016-09 affect all entities that issue share-based payment awards to their
employees and involve multiple aspects of the accounting for share-based payment transactions, including income tax consequences,
classification of awards as either equity or liabilities, and classification on the statement of cash flows. The ASU is effective for annual
periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any entity in
any interim or annual period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the
beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the
same period.  The Company adopted the ASU in the first quarter of 2017 and it did not have a material impact on the Company’s
consolidated financial statements. The impact of ASU 2016-09 as it relates to stock-based compensation for deferred tax assets and
liabilities balances were not material to the Company's consolidated financial statements.

In February 2016 the FASB issued ASU No. 2016-02 (ASU 2016-02) “Leases.” ASU 2016-02 amends a number of aspects of lease

accounting, including requiring lessees to recognize almost all leases with a term greater than one year as a right-of-use asset and
corresponding liability, measured at the present value of the lease payments. The guidance will become effective for the Company
beginning in the first quarter of 2019 with early adoption permitted and will be adopted using a modified retrospective approach. We are
evaluating the impact of the adoption of this standard on our consolidated financial statements, and expect our operating lease
commitments will be subject to the new standard and recognized as a right-of-use assets and operating lease liabilities upon adoption which
will increase our total assets and total liabilities as compared to amounts prior to adoption.

In May 2014 the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), or ASC 606. This standard

outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes
most current revenue recognition guidance, including industry-specific guidance. The main principle of ASU 2014-09 is to recognize
revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be
received for those goods or services. ASU 2014-09 provides companies with two implementation methods: (i) apply the standard
retrospectively to each prior reporting period presented (full retrospective application); or (ii) apply the standard retrospectively with the
cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings of the annual reporting
period that includes the date of initial application (modified retrospective application). This guidance is effective for annual reporting
periods beginning after December 15, 2017, including interim periods within that reporting period. Under Topic 606, an entity recognizes
revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity
expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are
within the scope of Topic 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the
performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance
obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. Topic 606 also impacts
certain other areas, such as the accounting for costs to obtain or fulfill a contract.

The Company will adopt ASC 606 during the first quarter of 2018 and using the modified retrospective method. The Company has

substantially completed its evaluation of the impact of adopting ASC 606 on its contracts with Bioverativ, Shire, DAS, and Sigma (as
defined below). The Company’s performance obligations with respect to Shire, DAS and Sigma were substantially complete at December
31, 2017 and any future receipts are contingent upon these counterparties achieving specified development, commercial, and/or sales
targets and would be in the form of milestones or royalties, all of which management concluded are constrained at December 31, 2017 as
defined under ASC 606. The Company has also performed an assessment of the impact of adopting ASC 606 on its Bioverativ
collaboration arrangement and has preliminarily concluded that the timing of the recognition of up-front payments and research and
development reimbursements will be decelerated under the new guidance while development and commercialization milestones are
constrained at December 31, 2017, as defined under ASC 606. Based on this assessment, management has preliminarily concluded that the
transition adjustment to be recognized on January 1, 2018 will be less than $5.0 million and will result in a decrease

83

 
 
 
to accumulated deficit and an increase to deferred revenue at that date as a result of decelerating the recognition of amounts related to
research and development reimbursements and up-front payments under ASC 606.

The Company has not completed its assessment of the effect that the adoption of ASC 606 will have on its agreements with Pfizer
that were entered into during 2017. The Company has preliminarily concluded that any potential milestone and royalty payments payable
under these agreements are constrained at December 31, 2017, as defined under ASC 606, and thus will not result in a change upon
adoption of ASC 606 from the accounting for such payments under ASC 605. No revenue or other amounts were recognized in 2017
related to the agreement that was entered into with Pfizer in late December 2017 and, accordingly, management does not expect any
amounts to be recognized as part of the January 2018 transition adjustment related to this agreement. During 2017, the Company
recognized as revenue $17.0 million of the $70.0 million up-front payment received from agreement the Company entered into with Pfizer
in May 2017, the amount and timing of which may change upon adoption of ASC 606.  

The estimates of the expected effects of the Company’s adoption of ASU 2014-09 represent management’s best estimates of the

effects of adopting ASU 2014-09 at the time of the preparation of this Annual Report on Form 10-K. The actual, final quantitative effects
of the adoption of ASU 2014-09 are subject to change from these estimates and such change may be significant, pending the completion of
the Company’s assessment in the first quarter of 2018.

NOTE 2 –FAIR VALUE MEASUREMENT

The Company measures certain assets and liabilities at fair value on a recurring basis, including cash equivalents, available-for-sale

securities and the contingent consideration liability. Fair value is determined based on a three-tier hierarchy under the authoritative
guidance for fair value measurements and disclosures that prioritizes the inputs used in measuring fair value as follows:

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets

or liabilities;

Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for

substantially the full term of the asset or liability; and

Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and

unobservable (i.e., supported by little or no market activity).

The fair value measurements of cash equivalents, available-for-sale securities and the contingent consideration liability are identified

at the following levels within the fair value hierarchy (in thousands):

The Company generally classifies its marketable securities as Level 2. Instruments are classified as Level 2 when observable market
prices for identical securities that are traded in less active markets are used. When observable market prices for identical securities are not
available, such instruments are priced using benchmark curves, benchmarking of like securities, sector groupings, matrix pricing and
valuation models. These valuation models are proprietary to the pricing providers or brokers and incorporate a number of inputs, including,
listed in approximate order of priority: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets,
benchmark securities, bids, offers and reference data including market research publications. For certain security types, additional inputs
may be used, or some of the standard inputs may not be applicable. Evaluators may prioritize inputs differently on any given day for any
security based on market conditions, and not all inputs listed are available for use in the evaluation process for each security evaluation on
any given day.

Contingent Consideration Liability

In August 2013 the Company acquired Ceregene and recorded a liability for the estimated fair value of contingent consideration

payments to former Ceregene stockholders, as outlined under the terms of the merger agreement with Ceregene. These contingent
payments are owed if the Company grants a third-party license to develop and commercialize certain product candidates acquired from
Ceregene, or if the Company commercializes any of such product candidates itself. The fair value of this liability is estimated using a
probability-weighted discounted cash flow analysis. Such valuations require significant estimates and assumptions including but not limited
to: determining the timing and estimated costs to complete the in-process projects, projecting regulatory approvals, estimating future cash
flows and developing appropriate discount rates. The Company has classified this liability as Level 3.

The subsequent changes in the fair value of the contingent consideration liability were recognized as a component of research and
development expense line item in the accompanying consolidated statements of operations as operating expenses. During the year ended
December 31, 2015, the recognized amount of the liability for contingent consideration decreased by the total fair value of the contingent

impairment of IPR&D assets acquired from Ceregene (see Note 6).

Collaboration Agreements

Collaboration and License Agreement with Pfizer Inc. in Human Therapeutics

SB-525 Global Collaboration and License Agreement

On May 10, 2017, Sangamo entered into an exclusive, global Collaboration and License Agreement (the “with Pfizer pursuant to

which Sangamo and Pfizer established a collaboration for the research, development and commercialization of SB-525, Sangamo’s gene
therapy product candidate for hemophilia A, and closely related products (the “hemophilia A Pfizer Agreement”).

Under the hemophilia A Pfizer Agreement, Sangamo will be responsible for conducting the Phase 1/2 clinical trial and certain
manufacturing activities for SB-525, while Pfizer will be responsible for subsequent worldwide development, manufacturing, marketing
and commercialization of SB-525.  Sangamo and Pfizer may also collaborate in the research and development of additional adeno-
associated virus (“AAV”)-based gene therapy products for hemophilia A.

Under the  hemophilia A Pfizer Agreement, Sangamo received an upfront fee of $70.0 million from Pfizer.  In addition, Sangamo is
eligible to receive $208.5 million in payments upon the achievement of specified clinical development, intellectual property and regulatory
milestones and $266.5 million in payments upon the achievement of specified first commercial sale milestones for SB-525 and potentially
other products. The total amount of potential clinical development, intellectual property, regulatory, and first commercial sale milestone
payments, assuming the achievement of all specified milestones in the hemophilia A Pfizer Agreement, is $475.0 million, which includes
up to $300.0 million for SB-525 and up to $175.0 million for other products that may be developed under the hemophilia A Pfizer
Agreement, subject to reduction on account of payments made under certain licenses for third party intellectual property.  In addition,
Pfizer has agreed to pay Sangamo royalties for each potential licensed product developed under the hemophilia A Pfizer Agreement that are
an escalating tiered, double-digit percentage of the annual net sales of such product and are subject to reduction due to patent expiration,
entry of biosimilar products to the market and payment made under certain licenses for third party intellectual property.  To date, no
milestone payments have been received and no products have been approved and therefore no royalty fees have been earned under the
hemophilia A Pfizer Agreement. Sangamo in responsible for internal and external research costs as part of the upfront fee and has the
ability to request additional reimbursement from Pfizer if certain conditions are met.

Subject to the terms of the hemophilia A Pfizer Agreement, Sangamo granted Pfizer an exclusive, worldwide, royalty-bearing
license, with the right to grant sublicenses, to use certain technology controlled by Sangamo for the purpose of developing, manufacturing
and commercializing SB-525 and related products. Under the hemophilia A Pfizer Agreement, Pfizer granted Sangamo a non-exclusive,
worldwide, royalty free, fully paid license, with the right to grant sublicenses, to use certain manufacturing technology developed under the
hemophilia A Pfizer Agreement and controlled by Pfizer to manufacture Sangamo’s products that utilize the AAV delivery system.  During
a specified period, neither Sangamo nor Pfizer will be permitted to clinically develop or commercialize, outside of the collaboration,
certain AAV-based gene therapy products for hemophilia A.

The Company has identified the deliverables within the hemophilia A Pfizer Agreement as a license to the technology and on-going
services. The Company concluded that the license is not a separate unit of accounting as it does not have stand-alone value to Pfizer apart
from the services to be performed by the Company pursuant to the hemophilia A Pfizer Agreement. As a result, the Company will
recognize revenue from the upfront payment on a straight-line basis over a thirty-two month estimated time over which the Company will
perform services under the hemophilia A Pfizer Agreement. The recognition period will be reviewed quarterly and adjusted, as needed, to
reflect the Company’s current assumptions regarding the period of performance. As of December 31, 2017, the Company had deferred
revenue of $53.0 million related to the hemophilia A Pfizer Agreement. During the year ended December 31, 2017 the Company
recognized revenue of $17.0 million related to the upfront fee that was received.

C9ORF72 Research Collaboration and License Agreement

On December 28, 2017, Sangamo entered into a Research Collaboration and License Agreement with Pfizer for the development and

commercialization of potential gene therapy products that use zinc finger protein transcription factors (“ZFP-TFs”) to treat amyotrophic
lateral sclerosis and frontotemporal lobar degeneration, or ALS/ FTLD, linked to mutations of the C9ORF72 gene. Pursuant to this Pfizer
Agreement, Sangamo will work together with Pfizer on a research program to identify, characterize and preclinically develop ZFP-TFs that
bind to and specifically reduce expression of the mutant form of the C9ORF72 gene (the “ALS/ FTLD Pfizer Agreement”). This agreement
was entered into as a separate and distinct agreement apart from the SB-525 Pfizer agreement. The Pfizer C9ORF72 agreement is related to
research specific ZFP-TF gene therapy for the C9ORF72 gene, while the SB-525 Pfizer agreement was for the clinical stage development
of AAV-based gene therapy products for hemophilia A.

Sangamo has granted Pfizer an exclusive, royalty-bearing, worldwide, sublicensable license under the Company’s relevant patents
and know-how to develop, manufacture and commercialize gene therapy products (“Licensed Products”) that use resulting ZFP-TFs that
satisfy pre-agreed criteria. During a specified period, neither Sangamo nor Pfizer will be permitted to research, develop, manufacture or
commercialize outside of the collaboration any zinc finger proteins that specifically bind to the C9ORF72 gene.

Under the terms of the ALS/ FTLD Pfizer Agreement, Sangamo received  a $12.0 million upfront payment from Pfizer. Each party

will be responsible for the cost of its performance of the research program. Pfizer will be operationally and financially responsible for
subsequent development, manufacturing and commercialization of Licensed Products. Sangamo is eligible to receive up to $60.0 million in
development milestone payments from Pfizer if a Licensed Product achieves specified preclinical development, clinical development and
first commercial sale milestones, and up to $90.0 million commercial milestone payments if annual worldwide net sales of Licensed
Products reach specified levels. In addition, Pfizer will pay royalties to Sangamo that are an escalating tiered, mid- to high-single digit
percentage of the annual worldwide net sales of Licensed Products. These royalty payments are subject to reduction due to patent
expiration, entry of biosimilar products to the market and payments made under certain licenses for third party intellectual property.
Sangamo did not recognize revenue related to this Pfizer agreement as the basic criteria for revenue recognition was not satisfied as of
December 31, 2017.

Collaboration and License Agreement with Bioverativ Inc. in Human Therapeutics

In January 2014, the Company entered into a Global Research, Development and Commercialization Collaboration and License

Agreement with Biogen (the “Bioverativ Agreement”), and in January 2017 this agreement was assigned by Biogen MA Inc. to Biogen’s
blood disorder spin-off, Bioverativ.  Pursuant to the Bioverativ Agreement, Sangamo and Bioverativ will collaborate to discover, develop,
seek regulatory approval for and commercialize therapeutics based on Sangamo’s zinc finger DNA-binding protein (“ZFP”) technology for
beta-thalassemia and sickle cell disease (“SCD”).

Under the Bioverativ Agreement, Sangamo and Bioverativ jointly conduct two research programs: the beta-thalassemia program and
the SCD program. For the beta-thalassemia program, Sangamo is responsible for all discovery, research and development activities through
the first human clinical trial for the first therapeutic developed under the Bioverativ Agreement for the treatment of beta-thalassemia. For
the SCD program, both parties are responsible for research and development activities through the submission of an Investigational New
Drug (“IND”) application for a ZFP-based therapeutic intended to treat SCD. For both programs, Bioverativ is responsible for subsequent
world-wide clinical development, manufacturing and commercialization of licensed products developed under the Bioverativ Agreement.
At the end of specified research terms for each program or under certain specified circumstances, Bioverativ has the right to step in and
take over any remaining activities of Sangamo. Furthermore, Sangamo has an option to co-promote in the United States any licensed
products to treat beta-thalassemia and SCD developed under the Bioverativ Agreement, and Bioverativ agrees to compensate Sangamo for
such co-promotion activities.

Sangamo received an upfront license fee of $20.0 million upon entering into the Bioverativ Agreement. In addition, the Company

will also be eligible to receive $115.8 million in payments upon the achievement of specified clinical development and regulatory
milestones, as well as $160.5 million in payments upon the achievement of specified sales milestones. Bioverativ reimburses Sangamo for
agreed upon costs incurred in connection with research and development activities conducted by Sangamo. In addition, if products are
commercialized under the Bioverativ Agreement, Bioverativ will pay Sangamo incremental royalties for each licensed product that are a
tiered double-digit percentage of annual net sales of such product. To date, no milestone payments have been received and no products
have been approved and therefore no royalty fees have been earned under the Bioverativ Agreement.

In January 2016, the parties agreed on an updated beta-thalassemia development plan and budget using the BCL11A erythroid
enhancer target. In November 2016, Sangamo and Bioverativ agreed on an updated beta-thalassemia development plan and budget. As a
result of this change, the Company updated the estimated performance period of the upfront license through June 2020, and updated the
milestones to be received based on the updated schedule and targets under the Bioverativ Agreement.

All contingent payments under the Bioverativ Agreement, when earned, will be non-refundable and non-creditable. The Company

has evaluated the contingent payments under the Bioverativ Agreement based on the authoritative guidance for research and development
milestones and determined that certain of these payments meet the definition of a milestone and that all such milestones are evaluated to
determine if they are considered substantive milestones. Milestones are considered substantive if they are related to events (i) that can be
achieved based in whole or in part on either the Company’s performance or on the occurrence of a specific outcome resulting from the
Company’s performance, (ii) for which there was substantive uncertainty at the date the agreement was entered into that the event would
be achieved and (iii) that would result in additional payments being due to the Company. Accordingly, consideration received for the
achievement of milestones that are determined to be substantive will be recognized as revenue in their entirety in the period when the
milestones are achieved and collectability is reasonably assured. Revenue for the achievement of milestones that are not substantive will be
recognized over the remaining period of the Bioverativ Agreement, assuming all other applicable revenue recognition criteria have been
met.

Subject to the terms of the Bioverativ Agreement, Sangamo has granted Bioverativ an exclusive, royalty-bearing license, with the

right to grant sublicenses, to use certain ZFP and other technology controlled by Sangamo for the purpose of researching, developing,
manufacturing and commercializing licensed products developed under the Bioverativ Agreement. Sangamo has also granted Bioverativ a
non-exclusive, world-wide, royalty free, fully paid license, with the right to grant sublicenses, under Sangamo’s interest in certain other
intellectual property developed pursuant to the Bioverativ Agreement.

The Company has identified the deliverables within the arrangement as a license to the technology and on-going research services
activities. The Company concluded that the license is not a separate unit of accounting as it does not have stand-alone value to Bioverativ
apart from the research services to be performed pursuant to the Bioverativ Agreement. As a result, the Company will recognize revenue
from the upfront payment on a straight-line basis over a forty-four month estimated research term as of the November 2016 modification
date, during which time the Company will perform research services. The estimated period of performance is reviewed quarterly and
adjusted, as needed, to reflect the Company’s current assumptions regarding the timing of its deliverables. As of December 31, 2017, the
Company had deferred revenue of $4.6 million related to the Bioverativ Agreement.

Amended Collaboration and License Agreement with Shire International GmbH in Human Therapeutics

In January 2012, the Company entered into a Collaboration and License Agreement with Shire (the “Shire Agreement ”), pursuant to

which the Company and Shire collaborate to research, develop and commercialize human therapeutics and diagnostics for monogenic
diseases based on Sangamo’s novel ZFP technology. This agreement was amended on September 1, 2015.  

Under the original Shire Agreement, the Company and Shire agreed to develop potential human therapeutic or diagnostic products for

seven gene targets. The initial four gene targets selected were blood clotting Factors VII, VIII, IX and X, and products developed for such
initial gene targets would be used for treating or diagnosing hemophilia A and B. In June 2012, Shire selected a fifth gene target for the
development of a ZFP therapeutic for Huntington’s disease. Shire had the right, subject to certain limitations, to designate two additional
gene targets. Pursuant to the Shire Agreement, the Company granted Shire an exclusive, world-wide, royalty-bearing license, with the right
to grant sublicenses, to use Sangamo’s ZFP technology for the purpose of developing and commercializing human therapeutic and
diagnostic products for the gene targets.

Under the terms of the Shire Agreement, the Company was responsible for all research activities through the submission of an IND

or European Clinical Trial Application (CTA), while Shire was responsible for clinical development and commercialization of products
generated from the research program from and after the acceptance of an IND or CTA for the product. Shire reimbursed Sangamo for
agreed upon internal and external program-related research costs. The Company received an upfront license fee of $13.0 million upon
entering into the Shire Agreement in 2012. In 2014, Sangamo recognized a $1.0 million milestone payment related to the hemophilia
program.

On September 1, 2015, the Shire Agreement was amended such that Shire agreed to return to Sangamo the exclusive, world-wide

rights to gene targets for the development and commercialization of ZFP therapeutics for hemophilia A and B.  Shire retains the rights and
will continue to develop a ZFP therapeutic for Huntington’s disease.  Sangamo will provide certain target feasibility services, and upon
Shire’s request, certain research activities according to a research plan as agreed upon by both companies. Such research activities
performed by Sangamo will be reimbursed by Shire. Shire’s rights with respect to other targets contemplated in the original agreement
revert to Sangamo. Under the revised agreement, each company is responsible for expenses associated with its own programs, and Shire
will reimburse Sangamo for any ongoing services provided by Sangamo for Shire’s programs. In 2015, Shire reimbursed Sangamo $3.4
million related to obligations prior to the amendment date which was recognized in revenue as the expense related to those obligations was
incurred. Sangamo has granted Shire a right of first negotiation to license the hemophilia A and B programs developed by Sangamo under
the amended agreement. Under the amended agreement, Shire does not have any milestone payment obligations with respect to the retained
programs, but it is required to pay single digit percentage royalties to Sangamo, up to a specified maximum cap, on the commercial sales of
ZFP therapeutic products from such programs. Under the Shire Agreement, Sangamo has full control over, and full responsibility for the
costs of, the hemophilia programs returned to us, subject to certain diligence obligations and Shire’s right of first negotiation to obtain a
license to such programs under certain circumstances. The Company is required to pay single digit percentage royalties to Shire, up to a
specified maximum cap, on commercial sales of ZFP therapeutic products from such returned programs.  

The Company has concluded that the license is not a separate unit of accounting as it does not have stand-alone value to Shire apart

from the research services to be performed pursuant to the Shire amendment. The Company satisfied the deliverables and research services
responsibilities within the amended arrangement which were completed in 2017. As a result, the Company recognized the remaining $2.3
million of deferred revenue from the upfront payment during the year ended December 31, 2017.

Agreement with Sigma-Aldrich Corporation (Sigma) in Laboratory Research Reagents, Transgenic Animal and Commercial Protein
Production Cell-line Engineering

In 2007, Sangamo entered into a license agreement with Sigma to provide Sigma with access to Sangamo’s proprietary ZFP

technology and the exclusive right to use the technology to develop and commercialize research reagent products and services in the
research field, excluding certain agricultural research uses that Sangamo previously licensed to DAS. Sangamo developed laboratory
research reagents using its ZFP technology over a three year research services period. Sangamo has since transferred the ZFP
manufacturing technology to Sigma.  

In October 2009, Sangamo expanded its license agreement with Sigma. In addition to the original terms of the license agreement,
Sigma received exclusive rights to develop and distribute ZFP-modified cell lines for commercial production of protein pharmaceuticals
and certain ZFP-engineered transgenic animals for commercial applications. Under the terms of the agreement, Sigma made an upfront
cash payment of $20.0 million consisting of a $4.9 million purchase of 636,133 shares of Sangamo common stock, valued at $4.9 million,
and a $15.1 million upfront license fee. Sangamo is also eligible to receive commercial license fees of $5.0 million based upon a percentage
of net sales and sublicensing revenue and thereafter a reduced royalty rate of 10.5% of net sales and sublicensing revenue. In addition, upon
the achievement of certain cumulative commercial milestones, Sigma will make milestone payments to Sangamo up to an aggregate of
$25.0 million. Sangamo does not have additional ongoing performance obligations under the agreement.

Agreement with Dow AgroSciences in Plant Agriculture

In 2005, Sangamo entered into an exclusive commercial license with Dow AgroSciences, LLC, or DAS, with an initial three year

research term. Under this agreement, Sangamo is providing DAS with access to its proprietary ZFP technology and the exclusive right to
use the technology to modify the genomes or alter the nucleic acid or protein expression of plant cells, plants, or plant cell cultures.
Sangamo has retained rights to use plants or plant-derived products to deliver ZFP TFs or ZFNs into humans or animals for diagnostic,
therapeutic or prophylactic purposes. In 2008 DAS exercised its option and obtained a commercial license to sell products incorporating or
derived from plant cells generated using the Company’s ZFP technology. The exercise of the option triggered a one-time commercial
license fee of $6.0 million, payment of the remaining $2.3 million of the previously agreed upon $4.0 million in research milestones,
development and commercialization milestone payments for each product, and royalties on sales of products. Furthermore, DAS has the
right to sublicense Sangamo’s ZFP technology to third parties for use in plant cells, plants, or plant cell cultures, and Sangamo will be
entitled to 25% of any cash consideration received by DAS under such sublicenses. In December 2010 the Company amended its
agreement with DAS to extend the period of reagent manufacturing services and research services through December 31, 2012.

The agreement with DAS also provides for minimum sublicense fees each year due to Sangamo every October, provided the
agreement is not terminated by DAS. Annual fees range from $250,000 to $3.0 million and total $25.3 million over 11 years unless
terminated at any time by DAS. The Company does not have any performance obligations. In the event of any termination of the
agreement, all rights to use the Company’s ZFP technology will revert to Sangamo, and DAS will no longer be permitted to practice
Sangamo’s ZFP technology or to develop or, except in limited circumstances, commercialize any products derived from the Company’s
ZFP technology.

Revenues under the agreement with DAS were $3.0 million during 2017 and $5.1 million and $3.0 million during 2016 and 2015,

respectively.

NOTE 6 – ACQUISITION OF CEREGENE

In August 2013, Sangamo acquired all the outstanding shares of Ceregene, a privately held biotechnology company focused on the
development of AAV gene therapies. The acquired assets included certain intellectual property rights relating to manufacturing of AAV,
and toxicology and data from Ceregene’s human clinical trials. The acquisition closed in October 2013 (the Closing Date).

The aggregate consideration transferred or transferable by Sangamo to former Ceregene stockholders at closing consisted of 100,000
shares of Sangamo common stock, with an approximate fair value of $1.2 million and a contingent earn-out of $1.5 million on the Closing
Date. The $1.8 million fair value of the contingent earn-out liability was reduced to zero in March 2015 upon Sangamo’s decision not to
pursue development of Ceregene’s technology as discussed below.  

Intangible Assets Acquired

Intangible assets acquired included In-Process Research and Development (IPR&D), which consisted of Ceregene’s two clinical
product candidates, CERE-110 for the treatment of AD and CERE-120 for the treatment of Parkinson’s disease. The Company determined
that the combined Closing Date estimated fair values of CERE-110 and CERE-120 was $1.9 million. In the first quarter of 2015, the
Company decided to discontinue the CERE-110 and CERE-120 clinical trial programs. As such, the probability of achieving projected
revenues and cash flows associated with these programs were adversely affected. The Company does not believe the programs have an
alternative future use for itself or other market participants. Accordingly, during the year ended December 31, 2015, the Company
recognized a $1.9 million impairment charge related to these assets.

Intangible assets also included $1.6 million in goodwill, the excess of the consideration transferred over the fair values assigned to
the assets acquired and liabilities assumed. Goodwill represents benefits that Sangamo believes will result from combining its operations
with the operations of Ceregene and any intangible assets that do not qualify for separate recognition, as well as any future, yet unidentified
products.  The Company tests goodwill for impairment on an annual basis or sooner, if deemed necessary. There have been no changes to
goodwill since the Closing Date, and no impairment has been recognized.

Richmond construction as a build-to-suit property within property and equipment, net, and recognize a corresponding build-to-suit lease
obligation for the same amount. Both buildings will depreciate over the period of their lease, respectively.

NOTE 8 – COMMITMENTS AND CONTINGENCIES

Sangamo occupies office and laboratory space under operating leases in Richmond, California. In August 2013, Sangamo amended

its lease agreement for our corporate headquarters wherein the lease was extended through August 2019. The Company has three additional
properties located in Richmond, CA. This includes two leases, one to occupy approximately 7,700 square feet of research and office space
that expires in August 2019, and another to occupy approximately 6,200 square feet of office space that expires in July 2021. Sangamo also
has two build-to-suit leases to occupy approximately 41,400 square feet of space in Richmond that expires in December 2021 and
approximately 87,700 square feet of space in Brisbane that expires in May 2029. Rent expense related to these lease agreements was $1.1
million, $1.0 million, and $0.9 million for 2017, 2016 and 2015, respectively. Future minimum payments under lease obligations at
December 31, 2017 consist of the following (in thousands):

For 2018, the company is committed to spend $8.8 million for tenant improvements related to the Brisbane build-to-suit lease and

$8.7 million as part of our services agreement with Brammer Bio MA, LLC, or Brammer, to provide dedicated capacity to supply our
preclinical and clinical programs. The Company also has $5.2 million of license commitments related to its intellectual property.

Contingencies

Sangamo is not party to any material pending legal proceeding. From time to time, we may be involved in legal proceedings arising in

the ordinary course of business.

NOTE 9 – STOCKHOLDERS’ EQUITY

Preferred Stock

The Company has 5,000,000 preferred shares authorized, which may be issued at the discretion of the Company’s Board of

Director’s discretion.

Common Stock

On June 26, 2017, Sangamo completed an underwritten public offering of its common stock, in which the Company sold an
aggregate of 11.5 million shares of its common stock at a public offering price of $7.25 per share. The net proceeds to Sangamo from the
sale of shares in this offering, after deducting underwriting discounts and commissions and other offering expenses, were approximately
$78.1 million.

At-the-Market Offering Agreements

On December 7, 2016, we entered into an “at the market” offering agreement with an investment bank, pursuant to which we may

issue and sell from time to time up to $75.0 million of our common stock through the bank as the sales agent (“ATM Agreement”). Under
the ATM Agreement, if we decide to sell shares, the sales agent will use its commercially reasonable efforts to sell on our behalf all of the
shares of common stock requested to be sold by us.  Sales of the common stock, if any, will be made at market prices by any method that is
deemed to be an “at the market offering” as defined in Rule 415 under the Securities Act, as amended, including sales made directly on The
Nasdaq Global Market and any other trading market for the common stock, and sales to or through a market maker other than on an
exchange. In addition, with our prior written consent, the sales agent may also sell our common stock in negotiated transactions.

On May 26, 2017, the Company entered into an Amended and Restated At-the-Market Offering Program Sales Agreement (the

“2017 ATM Agreement”) with an investment bank pursuant to which the Company may issue and sell from time to time after the date of
the 2017 ATM Agreement, shares of its common stock having an aggregate offering price of up to $75.0 million through the

93

 
 
 
 
   
 
 
   
 
 
   
   
   
   
   
 
 
 
investment bank acting as the Company’s sales agent. Under the 2017 ATM Agreement, if the Company decides to sell shares, the
Company will notify the sales agent, and the sales agent will use its commercially reasonable efforts to sell on the Company’s behalf all of
the shares of common stock requested to be sold.  Sales of the Company’s common stock, if any, will be made at market prices by any
method that is deemed to be an “at the market offering” as defined in Rule 415 under the Securities Act, as amended, including sales made
directly on The NASDAQ Global Select Market and sales to or through a market maker other than on an exchange. In addition, with the
Company’s prior written consent, the sales agent may also sell shares of its common stock in negotiated transactions under the 2017 ATM
Agreement.  During the three months ended March 31, 2017, the Company issued a total of 871,149 shares of its common stock under the
original At-the-Market Offering Program Sales Agreement entered into with the sales agent in December 2016, and received net proceeds
of $3.4 million, after deducting offering expenses, including $0.1 million of commission paid to the sales agent. These shares were
inadvertently sold under a registration statement filed with the SEC that had in fact expired prior to the time the shares were
sold.  Consequently, the Company may be subject to claims for rescission by purchasers who purchased shares of common stock under the
ATM Agreement in March 2017.  Under Section 12(a)(1) of the Securities Act, a purchaser of security in a transaction made in violation of
Section 5 of the Securities Act may obtain recovery of the consideration paid in connection with its purchase, plus statutory interest, or, if it
had already sold the shares, recover damages resulting from its purchase. While the Company believes it is unlikely that a successful claim
will be asserted against the Company by any purchasers who purchased shares of common stock under the ATM Agreement in March
2017, the Company cannot guarantee that no such legal claims will be asserted against the Company by any purchasers. In addition, the
Company could become subject to enforcement actions and/or penalties and fines by federal authorities, and the Company is unable to
predict the likelihood of any such enforcement actions being brought, or the amount of any such potential penalties or fines.

Stock Incentive Plan

In April 2013 Sangamo’s Board of Directors adopted, subject to stockholder approval, the Company’s 2013 Stock Incentive Plan (the

2013 Plan) as the successor to the Company’s 2004 Stock Incentive Plan (the 2004 Plan). At the Annual Meeting of Stockholders held on
June 12, 2013, the 2013 Plan was approved by the Company’s stockholders and became effective. In connection with the approval by
stockholders of the 2013 Plan, outstanding awards under the 2004 Plan were transferred to the 2013 Plan. The 2004 Plan was terminated
and no further awards will be made pursuant to the 2004 Plan.

Under the 2013 Plan, the exercise price per share of options granted will generally not be less than 100 percent of the fair value per
share of common stock on the grant date, and the option term will not exceed ten years. If the person to whom the option is granted is a 10
percent stockholder, and the option granted qualifies as an Incentive Stock Option Grant, then the exercise price per share will not be less
than 110 percent of the fair value per share of common stock on the grant date, and the option term will not exceed five years. Options
granted under the 2013 Plan generally vest over four years at a rate of 25 percent one year from the grant date and one thirty-sixth per
month thereafter and expire ten years after the grant, or earlier upon employment termination. Certain options previously granted under the
2004 Plan to the Company’s non-employee directors are structured so that they may be exercised prior to vesting, with the related shares
subject to Sangamo’s right to repurchase any shares that have not vested pursuant to the vesting schedule in effect for such award at the
exercise price paid if the option holder’s board service terminates. Approximately 14.1 million shares were initially reserved for issuance
under the 2013 Plan, including 9.7 million shares of common stock subject to outstanding awards previously granted under the 2004 Plan
that were transferred to the 2013 Plan, and an additional 4.4 million shares of common stock.

The number of shares of common stock reserved for issuance under the 2013 Plan will be reduced: (i) on a 1-for-1 basis for each

share of common stock subject to a stock option or stock appreciation right granted under the plan, (ii) on a 1-for-1 basis for each share of
common stock issued pursuant to a full value award granted under the plan prior to the plan effective date, and (iii) by a fixed ratio of 1.33
shares of common stock for each share of common stock issued pursuant to a full-value award granted under the plan on or after the plan
effective date.

Shares subject to any outstanding options or other awards under the 2013 Plan that expire or otherwise terminate prior to the issuance

of the shares subject to those options or awards will be available for subsequent issuance under the 2013 Plan. Any unvested shares issued
under the 2013 Plan that the Company subsequently purchases, pursuant to repurchase rights under the 2013 Plan, will be added back to the
number of shares reserved for issuance under the 2013 Plan on a 1-for-1 basis or a 1.33-for-1 basis (depending on the ratio at which the
share reserve was debited for the original award) and will accordingly be available for subsequent issuance in accordance with the terms of
the plan.

In June 2015 Sangamo’s stockholders were asked to vote to approve the amendment and restatement of our 2013 Stock Incentive

Plan in order to increase the number of shares in our common stock reserved for issuance over the term of the 2013 Plan by 5,300,000
shares. At the Annual Meeting of Stockholders held on June 22, 2015, the amendment and restatement of our 2013 Stock Incentive Plan
was approved by the Company’s stockholders and became effective.

94

 
On November 10, 2017, the Compensation committee of the Company’s Board of Directors approved the amendment and

restatement of the Company’s Amended and Restated 2013 Stock Incentive Plan, to reserve an additional one million shares of the
Company’s common stock to be used exclusively for grants of awards to individuals who were not previously employees or non-
employee directors of the Company (or following a bona fide period of non-employment with the Company), as an inducement material to
each such individual’s entry into employment with us within the meaning of Rule 5635(c)(4) of the NASDAQ Listing Rules, or Rule
5635(c)(4). The 2013 Plan was amended and restated by the Compensation Committee without stockholder approval pursuant to Rule
5635(c)(4).

Employee Stock Purchase Plan

Sangamo’s 2010 Employee Stock Purchase Plan (“Purchase Plan”), which supersedes the Company’s 2000 Employee Stock

Purchase Plan, provides a total reserve of 2,100,000 shares of common stock for issuance under the Purchase Plan. Eligible employees may
purchase common stock at 85 percent of the lesser of the fair market value of Sangamo’s common stock on the first day of the applicable
two-year offering period or the last day of the applicable six-month purchase period.

Restricted Stock Units

During 2017, 2016 and 2015, the Company awarded 12,600, 60,000, and 446,000  Restricted Stock Units (RSUs), respectively. The

RSUs awarded in 2017, 2016 and 2015 had an average grant date fair value per award of $15.85, $5.16 and $9.45, respectively. These
awards generally vest as follows: one-third of the award will vest in a series of three successive equal annual installments. The aggregate
fair value of RSUs vested during 2017, 2016 and 2015 was $1.2 million, $4.8 million and $4.1 million, respectively.

RSUs that vested in 2017, 2016 and 2015 were net-share settled such that the Company withheld shares with value equivalent to the
employees’ minimum statutory obligation for the applicable income and other employment taxes, and remitted the cash to the appropriate
taxing authorities. The total shares withheld were approximately 42,243, 165,181, and 172,807 for 2017, 2016 and 2015, respectively and
were based on the value of the RSUs on their respective issuance dates as determined by the Company’s closing stock price. Total
payments for the employees’ tax obligations to taxing authorities were $0.7 million, $0.8 million and $1.5 million in 2017, 2016 and 2015,
respectively and are reflected as a financing activity within the accompanying consolidated statements of cash flows. These net-share
settlements had the effect of share repurchases by the Company as they reduced and retired the number of shares that would have otherwise
been issued as a result of the vesting and did not represent an expense to the Company.

As of December 31, 2017, there were 3,601,633 shares reserved for future awards under the Company’s 2013 Plan and 835,674

shares of common stock reserved for future issuance under the Purchase Plan.

In October 2013, we acquired Ceregene.  The Company recorded goodwill and intangible assets as part of accounting for the

acquisition of Ceregene. A portion of the intangible assets acquired were for the use in a particular research and development project
IPR&D and are considered indefinite-lived assets with no tax basis. In 2015, the Company impaired these intangible assets and reversed
the corresponding deferred tax liability.

In 2015 the Company received a $14.5 million Section 16(b) disgorgement settlement that was r ecognized as additional paid-in

capital. The disgorgement settlement was recognized net of taxes of $9.5 million, which resulted in an income tax benefit of $5.0 million
being recognized in the accompanying consolidated statements of operations for the year ended December 31, 2015.

The changes in the fair value of the unrealized gain/loss on securities investment are recorded as a component of accumulated other

comprehensive income, net of a provision for income taxes.  

A valuation allowance is recorded when it is more likely than not that all or some portion of the deferred income tax assets will not

be realized. We regularly assess the need for a valuation allowance against our deferred income tax assets by considering both positive and
negative evidence related to whether it is more likely than not that our deferred income tax assets will be realized. In evaluating our ability
to recover our deferred income tax assets within the jurisdiction from which they arise, we consider all available positive and negative
evidence, including scheduled reversals of deferred income tax liabilities, projected future taxable income, tax-planning strategies, and
results of recent operations. Accordingly, based upon the Company’s analysis of these factors the net deferred tax assets have been fully
offset by a valuation allowance. The valuation allowance (decreased) increased by $(28.9) million, $23.8 million and $5.0 million for the
years ended December 31, 2017, 2016 and 2015, respectively. As of December 31, 2017, Sangamo had net operating loss carryforwards for
federal and state income tax purposes of approximately $475 million and $142 million, respectively. If not utilized, the net federal and state
operating loss carryforwards will expire in 2018 and 2017, respectively. The Company also has federal and state research tax credit
carryforwards of $10.8 million and $11.8 million, respectively. The federal research credits will begin to expire in 2018 while the state
research credits have no expiration date. Utilization of the Company’s net operating loss carryforwards and research tax credit
carryforwards may be subject to substantial annual limitations due to the ownership change limitations provided by the Internal Revenue
Code and similar state provisions. The annual limitation could result in the expiration of the net operating loss carryforwards and research
tax credit carryforwards before utilization.

On December 22, 2017, President Trump signed the Tax Cuts and Jobs Act ("Tax Reform") into legislation.  The Tax Reform makes
significant changes to the US corporate income tax law including, but not limited to, (1) reducing the U.S. federal corporate tax rate to 21%
from 35% and (2) requiring a one-time mandatory transition tax on previously deferred foreign earnings of US subsidiaries.  Under ASC
740, the effects of changes in tax rates and laws are recognized in the period in which the new legislation is enacted.  In the case of US
federal income taxes, the enactment date is the date the bill becomes law.    With respect to this legislation, we expect no financial
statement impact due to the Company's valuation allowance.  The Company performed a re-measurement of deferred tax assets and
liabilities as a result of the decrease in the corporate Federal income tax rate from 35% to 21%. In addition to the reduction of U.S. federal
corporate tax rate, the Company has also considered the impact of the foreign transition tax for which it has estimated that it would not
need to accrue any amounts.

In December 2017, the Securities and Exchange Commission staff issued Staff Accounting Bulletin No.118 (SAB 118) to provide
guidance on the application of the Tax Reform when a company does not have the necessary information available, prepared, or analyzed
in reasonable to detail to reflect the effects of the Tax Reform.  SAB 118 provides guidance for companies under the three scenarios (1)
measurement of certain income tax effects is complete, (2) measurement of certain income tax effect can be reasonably estimated, and (3)
measurement of certain income tax effects cannot be reasonably estimated.  Companies are to complete the accounting under ASC 740 in
regards to the Tax Reform within a measurement period that does not extend one year from the date of enactment (i.e., December 22,
2018).  In accordance with SAB 118, companies must reflect the tax effects of the Tax Reform for which the accounting under 740 is
complete. If certain income tax effect can be reasonably estimated, then the companies must report provisional amounts in the reporting
period in which the companies can determine the reasonable estimate during the measurement period.  In the case that certain income tax
effects cannot be reasonably estimated, companies do not have to report effects of the Tax Reform.  However, they should continue to
apply ASC 740 based on the rules before the enactment of the Tax Reform and report any income tax effects in the first reporting period in
which reasonable estimates become available.

We expect the new law to significantly reduce our tax rate in future periods, and our tax footnote reflects the effects of a Federal tax

rate reduction net of our valuation allowance, which resulted in a net overall reduction of $0. 

The final transition impacts of the Tax Act may differ from the above estimate, possibly materially, due to, among other things,
changes in interpretations of the Tax Act, any legislative action to address questions that arise because of the Tax Act, any changes in
accounting standards for income taxes or related interpretations in response to the Tax Act, or any updates or changes to estimates the
company has utilized to calculate the transition impacts, including impacts from changes to current year earnings estimates and foreign
exchange rates of foreign subsidiaries.  In accordance with SAB 118, the Company is allowed a measurement period of up to one year after
the enactment date of the Tax Act to finalize the recording of the related tax impacts.  We currently anticipate finalizing and recording any
resulting adjustments by year ending December 31, 2018.

The Company files federal and state income tax returns with varying statutes of limitations. The tax years from 2002 forward remain
open to examination due to the carryover of net operating losses or tax credits. The Company also files a UK income tax return, and the tax
years from 2008 and thereafter remain open to examination.

The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. As of

December 31, 2017, the Company had no accrued interest and/or penalties. The unrecognized tax benefits may change during the next year
for items that arise in the ordinary course of business. In the event that any unrecognized tax benefits are recognized, the effective tax rate
will not be affected.

NOTE 14 – BUILD-TO-SUIT LEASE

Brisbane Build-to-Suit Lease

In November 2017, the Company entered into a long-term property lease which includes construction by the lessor of a building with

approximately 87,700 square feet of space, in Brisbane, California. Substantial completion of the building is estimated to occur in the last
quarter of 2018. The lease agreement expires in May 2029, approximately ten years after substantial completion of the building. A letter of
credit for $3.5 million was established as the deposit and is classified within other noncurrent assets in the financial statements. The
Company has two options to extend the lease term for up to a combined additional ten years.

The Company is deemed, for accounting purposes only, to be the owner of the entire project including the building shell, even
though it is not the legal owner as a result of the cold shell condition of the building and involvement in the construction process. In
connection with the Company’s accounting for this transaction, the Company capitalized the costs of construction as a build-to-suit
property within property and equipment, net, and recognize a corresponding build-to-suit lease obligation, including interest. Fair value of
the building was estimated at $20.9 million using comparable market prices per square foot for similar space for public real estate
transactions in the surrounding area and is considered a Level 2 fair value measurement. As of December 31, 2017, $21.2 million was
capitalized with a corresponding build-to-suit lease obligation recognized related to this lease for the building and construction costs.  

Point Pinole Build-to-Suit Lease

In December 2015, the Company entered into a long-term property lease which includes construction by the lessor of a building with
approximately 41,400 square feet of space, in Richmond, California. Substantial completion of the building was accomplished in December
2016 at which time the lease commenced. The lease agreement expires in December 2021, five years after substantial completion of the
building. The Company has two options to extend the lease term for up to a combined additional ten years.

The Company is deemed, for accounting purposes only, to be the owner of the entire project including the building shell, even

though it is not the legal owner. In connection with the Company’s accounting for this transaction, the Company capitalized the costs of
construction as a build-to-suit property within property and equipment, net, and recognize a corresponding build-to-suit lease obligation for
the same amount. As of December 31, 2016, $3.9 million of costs were capitalized in buildings with a corresponding build-to-suit lease
obligation recognized related to this lease.

Construction has completed on the facility and as such a portion of the monthly lease payment is allocated to land rent and recorded
as an operating lease expense and the non-interest portion of the amortized lease payments to the landlord related to the rent of the building
is applied to reduce the build-to-suit lease obligation.

NOTE 15 – CLAIMS SETTLEMENT

In September 2015, the Company received $14.5 million as a settlement with certain institutional investors that were beneficial

owners of Sangamo’s common stock related to the disgorgement of short-swing profits pursuant to Section 16(b) of the Securities
Exchange Act of 1934, as amended.  The settlement of $9.5 million, net of a $5.0 million income tax benefit and certain expenses, was
recognized as additional paid-in capital.

NOTE 16 – SUBSEQUENT EVENT

In February 2018, the Company entered into a Collaboration and License Agreement with Kite Pharma, Inc. (“Kite”), a wholly-

owned subsidiary of Gilead Sciences, Inc. (“Gilead”), for the research, development and commercialization of potential engineered cell
therapies for cancer. The Company will work together with Kite on a research program under which the Company ZFNs and AAVs to
disrupt and insert certain genes in T cells and NK cells, including the insertion of genes that encode CARs, T-cell receptors (“TCRs”) and
NK cell receptors (“NKRs”) directed to mutually agreed targets.  Kite will be responsible for all clinical development and
commercialization of any resulting products. Except for confidentiality obligations and certain representations, warranties and covenants,
which are effective upon execution, the effectiveness of the Kite agreement is subject to the expiration or termination of all applicable
waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended and other customary closing conditions.

Under the terms of the Kite agreement, the Company will, upon the effectiveness of the Kite agreement, receive a $150 million
upfront  payment  from  Kite.  Kite  will  reimburse  the  Company’s  direct  costs  to  conduct  the  joint  research  program  under  the  Kite
agreement, and Kite will be operationally and financially responsible for all subsequent development, manufacturing and commercialization
of licensed products. The Company is also eligible to receive contingent development- and sales-based milestone payments that could total
up  to  $3.01  billion  if  all  of  the  specified  milestones  set  forth  in  the  Kite  agreement  are  achieved.  Of  this  amount,  approximately  $1.26
billion relates to the achievement of specified research, clinical development, regulatory and first

100

 
 
 
 
 
commercial  sale  milestones,  and  approximately  $1.75  billion  relates  to  the  achievement  of  specified  sales-based  milestones  if  annual
worldwide net sales of licensed products reach specified levels. Each development- and sales-based milestone payment is payable (i) only
once for each licensed product, regardless of the number of times that the associated milestone event is achieved by such licensed product,
and (ii) only for the first ten times that the associated milestone event is achieved, regardless of the number of licensed products that may
achieve such milestone event.  In addition, the Company will be entitled to receive escalating, tiered royalty payments with a percentage in
the mid-single digits based on potential future annual worldwide net sales of licensed products. These royalty payments will be subject to
reduction  due  to  patent  expiration,  entry  of  biosimilar  products  to  the  market  and  payments  made  under  certain  licenses  for  third-party
intellectual property.  At this time the Company is assessing the accounting impact of the agreement.

DISCLOSURE

None.

ITEM 9A – CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to provide reasonable assurance that information required to be
disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the Securities
and Exchange Commission’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.

Under  the  supervision  of  our  principal  executive  officer  and  principal  financial  officer,  we  evaluated  the  effectiveness  of  our
disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) as of December 31, 2017.  Based on
that evaluation, as of December 31, 2017, our principal executive officer and principal financial officer have concluded that our disclosure
controls and procedures were effective at the reasonable assurance level.

Inherent Limitations on Controls and Procedures

Our  management,  including  the  principal  executive  officer  and  principal  financial  officer,  does  not  expect  that  our  disclosure
controls and procedures and our internal control over financial reporting will prevent all error and all fraud. A control system, no matter
how well designed and operated, can only provide reasonable assurances that the objectives of the control system are met. The design of a
control system reflects resource constraints; the benefits of controls must be considered relative to their costs. Because there are inherent
limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if
any,  for  our  company  have  been  or  will  be  detected. As  these  inherent  limitations  are  known  features  of  the  disclosure  and  financial
reporting  processes,  it  is  possible  to  design  into  the  processes  safeguards  to  reduce,  though  not  eliminate,  these  risks.  These  inherent
limitations  include  the  realities  that  judgments  in  decision-making  can  be  faulty  and  that  breakdowns  occur  because  of  simple  error  or
mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management
override  of  the  control.  The  design  of  any  system  of  controls  is  based  in  part  upon  certain  assumptions  about  the  likelihood  of  future
events. While our disclosure controls and procedures and our internal control over financial reporting are designed to provide reasonable
assurance of achieving their objectives, there can be no assurance that any design will succeed in achieving its stated goals under all future
conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with
the policies or procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may
occur and not be detected.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining an adequate internal control over financial reporting (as such term
is  defined  in  Rules  13a-15(f)  and  15d-15(f)  of  the  Exchange Act)  for  our  company.  Our  management,  including  our  principal  executive
officer and principal financial officer, conducted an evaluation of the effectiveness of our internal control over financial reporting based on
the  framework  set  forth  in  the  “Internal  Control—Integrated  Framework”  issued  by  the  Committee  of  Sponsoring  Organizations  of  the
Treadway  Commission  (2013  framework).  Based  on  an  evaluation  under  that  framework,  our  management  concluded  that  our  internal
control over financial reporting was effective at the reasonable assurance level as of December 31, 2017.  

The effectiveness of our internal control over financial reporting as of December 31, 2017 has been audited by Ernst & Young LLP,

an independent registered public accounting firm, as stated in their report, which is included herein.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting identified in connection with the evaluation required by
Rules 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the three months ended December 31, 2017 that has materially
affected, or is reasonably likely to materially affect, our internal control over financial reporting.

The Board of Directors and Stockholders of Sangamo Therapeutics, Inc.

Report of Independent Registered Public Accounting Firm

Opinion on Internal Control over Financial Reporting
We have audited Sangamo Therapeutics, Inc.’s internal control over financial reporting as of December 31, 2017, based on criteria
established in Internal Control Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission
(2013 framework) (the COSO criteria). In our opinion, Sangamo Therapeutics, Inc. (the Company) maintained, in all material respects,
effective internal control over financial reporting as of December 31, 2017, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the
2017 consolidated financial statements of the Company and our report dated March 1, 2018 expressed an unqualified opinion thereon.

Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the
effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over
Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our
audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in
accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and
the PCAOB.  

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists,
testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other
procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting
principles. A company’s internal control over financial reporting 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 the assets of the company; (2) provide
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally
accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of
management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of
any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in
conditions, or that the degree of compliance with the policies or procedures may deteriorate.

RESTRICTED STOCK UNIT ISSUANCE AGREEMENT

EXHIBIT 10.2

RECITALS

A.

B.

C.

The Board has adopted the Plan for the purpose of retaining the services of selected
Employees,  non-employee  members  of  the  Board  (or  the  board  of  directors  of  any  Parent  or
Subsidiary) and consultants and other independent advisors who provide services to the Corporation
(or any Parent or Subsidiary).

Participant  is  to  render  valuable  services  to  the  Corporation  (or  a  Subsidiary),  and
this Agreement  is  executed  pursuant  to,  and  is  intended  to  carry  out  the  purposes  of,  the  Plan  in
connection with the Corporation’s issuance of shares of Common Stock to the Participant under the
Stock Issuance Program.

All capitalized terms in this Agreement shall have the meaning assigned to them in

the attached Appendix A.

NOW, THEREFORE, it is hereby agreed as follows:

1.

Grant of Restricted Stock Units .  The Corporation hereby awards to the Participant, as of
the Award Date, Restricted Stock Units under the Plan. Each Restricted Stock Unit represents the right to receive one
share  of  Common  Stock  on  the  specified  issuance  date  following  the  vesting  of  that  unit.    The  number  of  shares  of
Common Stock subject to the awarded Restricted Stock Units, the applicable vesting schedule for those shares, the date
on which those vested shares shall become issuable to Participant and the remaining terms and conditions governing
the award (the “Award”) shall be as set forth in this Agreement.

Award Date:

Number  of  Shares
Subject to Award:

Vesting Schedule:

AWARD SUMMARY

[             ] shares of Common Stock (the “Shares”)  

Provided  the  Participant  continues  in  Service  through  each  date,  50%  of  the
Shares shall vest on the six-month anniversary of the Award Date and 50% of
the  Shares  shall  vest  on 
the  Award
Date.  However, one or more Shares may be subject to accelerated vesting in
accordance with the provisions of Paragraph 5 of this Agreement.

the  one-year  anniversary  of 

 
 
 
 
 
Issuance Schedule:

Subject to Paragraph 7 of this Agreement, each Share in which the Participant
vests in accordance with the Vesting Schedule above shall be issued, subject to
the  Corporation’s  collection  of  all  applicable  Withholding  Taxes,  on  the  date
that  particular  Share  vests  or  as  soon  after  that  scheduled  vesting  date  as
administratively  practicable  (the  “Issue  Date”),  but  in  no  event  later  than  the
later of (i) the close of the calendar year in which such vesting date occurs or
(ii)  the  fifteenth  day  of  the  third  calendar  month  following  such  vesting
date.    The  issuance  of  the  Shares  shall  be  subject  to  the  Corporation’s
collection  of  all  applicable  Withholding  Taxes.    The  procedures  pursuant  to
which  the  applicable  Withholding  Taxes  are  to  be  collected  are  set  forth  in
Paragraph 7 of this Agreement.

2.

Limited  Transferability.    Prior  to  the  actual  issuance  of  the  Shares
which  vest  hereunder,  the  Participant  may  not  transfer  any  interest  in  the Award  or  the  underlying  Shares;  provided,
however, any Shares which vest hereunder but which otherwise remain unissued at the time of the Participant’s death
may be transferred pursuant to the provisions of the Participant’s will or the laws of inheritance or to the Participant’s
designated beneficiary or beneficiaries of this Award.  The Participant may also direct the Corporation to issue stock
certificates  for  any  Shares  which  in  fact  vest  and  become  issuable  hereunder  to  one  or  more  designated  Family
Members  or  a  trust  established  for  the  Participant  and/or  his  or  her  Family  Members.    The  Participant  may  make  a
beneficiary designation or certificate directive for this Award at any time by filing the appropriate form with the Plan
Administrator or its designee.

3.

Cessation  of  Service .    Except  as  otherwise  provided  in  Paragraph  5  below,  should  the
Participant cease Service for any reason prior to vesting in one or more Shares subject to this Award, then the Award
will be immediately cancelled with respect to those unvested Shares, and the number of Restricted Stock Units will be
reduced accordingly.  The Participant shall thereupon cease to have any right or entitlement to receive any Shares under
those cancelled units.

4.

Stockholder  Rights.    The  holder  of  this  Award  shall  not  have  any  stockholder  rights,
including voting or dividend rights, with respect to the Shares subject to the Award until the Participant becomes the
record  holder  of  those  Shares  following  their  actual  issuance  upon  the  Corporation’s  collection  of  the  applicable
Withholding Taxes.

5.

Change in Control .

Any  Restricted  Stock  Units  subject  to  this Award  at  the
time of a Change in Control may be assumed by the successor entity or otherwise continued in full force and effect.  In
the event of such assumption or continuation of the Award, no accelerated vesting of the Restricted Stock Units shall
occur at the time of the Change in Control.

(a)

(b)

In the event the Award is assumed or otherwise continued
in effect, the Restricted Stock Units subject to the Award shall be adjusted immediately after the consummation of the
Change  in  Control  so  as  to  apply  to  the  number  and  class  of  securities  into  which  the  Shares  subject  to  those  units
immediately prior to the Change in Control would have been converted in consummation of that Change in Control had
those Shares actually been issued and outstanding at that time.

-2-

 
 
 
 
(c)

If the Restricted Stock Units subject to this Award at the
time of the Change in Control are not assumed or otherwise continued in effect in accordance with Paragraph 5(a), then
those units will vest immediately upon the closing of the Change in Control. The Shares subject to those vested units
will be issued immediately at that time or as soon as administratively practicable thereafter, but in no event more than
fifteen  (15)  business  days  after  such  closing,  or  will  otherwise  be  converted  into  the  right  to  receive  the  same
consideration per share of Common Stock payable to the other shareholders of the Corporation in consummation of the
Change in Control and distributed at the same time as such stockholder payments, but the distribution to the Participant
shall in no event be made later than the later of (i) the close of the calendar year in which the Change in Co ntrol  is
effected or (ii) the fifteenth (15th) day of the third (3rd) calendar month following the effective date of such Change in
Control.

This Agreement  shall  not  in  any  way  affect  the  right  of
the  Corporation  to  adjust,  reclassify,  reorganize  or  otherwise  change  its  capital  or  business  structure  or  to  merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets.

(d)

6.

Adjustment in Shares.  Should any change be made to the outstanding Common Stock by
reason  of  any  stock  split,  stock  dividend,  recapitalization,  combination  of  shares,  exchange  of  shares,  spin-off
transaction  or  other  change  affecting  the  outstanding  Common  Stock  as  a  class  without  the  Corporation’s  receipt  of
consideration, or should the value of the outstanding shares of Common Stock be substantially reduced as a result of a
spin-off  transaction  or  an  extraordinary  dividend  or  distribution  or  should  there  occur  any  merger,  consolidation  or
other reorganization (including, without limitation, a Change in Control transaction) then equitable adjustments shall be
made  to  the  total  number  and/or  class  of  securities  issuable  pursuant  to  this  Award  in  such  manner  as  the  Plan
Administrator  deems  appropriate  in  order  to  reflect  such  change  and  thereby  prevent  the  dilution  or  enlargement  of
benefits hereunder.

7.

Issue Date and Collection of Withholding Taxes .  

(a)

Except as otherwise provided in Paragraph 5,  if:

to
Withholding  Taxes  on  the  Issue  Date  specified  in  the  Issuance  Schedule  above  in  Paragraph  1  (the  “Original  Issue
Date”),

is  otherwise  subject 

this  Award 

(i)

(ii)

the  Original  Issue  Date  does  not  occur
(x) during an “open window period” applicable to the Participant, as determined by the Corporation in accordance with
the  Corporation’s  trading  policies  governing  the  sale  of  Common  Stock,  or  (x)  on  a  date  when  the  Participant  is
otherwise permitted to sell shares of Common Stock on an established stock exchange or stock market (including, but
not  limited  to,  under  a  previously  established  10b5-1  trading  plan  entered  into  in  compliance  with  the  Corporation’s
policies), and

the  Corporation  elects,  prior  to  the
Original Issue Date, (x) not to satisfy such Withholding Taxes through the Share Withholding Method (as defined in
subparagraph (c) of this Paragraph 7) and (y) not to permit the Participant to pay such Withholding Taxes in cash (or by
check),

(iii)

-3-

 
 
 
 
then the Shares that would otherwise be issued to the Participant on the Original Issue Date will not be issued to the
Participant on the Original Issue Date and will instead be issued to the Participant on the first business day when the
Participant is not prohibited from selling shares of Common Stock on an established stock exchange or stock market,
but in no event later than the later of (i) the close of the calendar year in which the vesting date with respect to such
Shares occurs or (ii) the fifteenth day of the third calendar month following such vesting date.

Upon  the  applicable  Issue  Date,  the  Corporation  shall
issue  to  or  on  behalf  of  the  Participant  a  certificate  (which  may  be  in  electronic  form)  for  the  applicable  number  of
underlying shares of Common Stock, subject, however, to the Corporation’s collection of the applicable Withholding
Taxes.

(b)

The Withholding Taxes required to be withheld with respect to the issua nce of
the vested Shares hereunder shall be collected from the Participant through any of the following alternatives, in the sole
discretion of the Corporation:

(c)

(i)
Corporation in the amount of such taxes;

the  Participant’s  delivery  of  his  or  her  separate  check  payable  to  the

the use of the proceeds from a next-day sale of the Shares issued to the
Participant, provided and only if (i) such a sale is permissible under the Corporation’s trading policies governing the
sale  of  Common  Stock,  (ii)  the  Participant  makes  an  irrevocable  commitment,  on  or  before  the  Issue  Date  for  those
Shares, to effect such sale of the Shares and (iii) the transaction is not otherwise deemed to constitute a prohibited loan
under Section 402 of the Sarbanes-Oxley Act of 2002; or

(ii)

(iii)

through  a  share  withholding  procedure  pursuant  to  which  the
Corporation will withhold, at the time of such issuance, a portion of the Shares with a Fair Market Value (measured as
of the issuance date) equal to the amount of those taxes (the “Share Withholding Method”); provided, however, that the
amount  of  any  Shares  so  withheld  shall  not  exceed  the  amount  necessary  to  satisfy  the  Corporation’s  required  tax
withholding obligations using the minimum statutory withholding rates for federal, state, local and foreign tax purposes
that are applicable to supplemental taxable income.

(d)

Notwithstanding  anything  to  the  contrary  in  this  Paragraph  7,  the  employee
portion  of  the  federal,  state,  local  and  foreign  employment  taxes  required  to  be  withheld  by  the  Corporation  in
connection  with  the  vesting  of  the  Shares  (the  “Employment  Taxes”)  shall  in  all  events  be  collected  from  the
Participant no later than the last business day of the calendar year in which the Shares vest hereunder.  Accordingly, to
the extent the Issue Date for one or more vested Shares is to occur in a year subsequent to the calendar year in which
those Shares vest, the Participant shall, on or before the last business day of the calendar year in which the Shares vest,
deliver to the Corporation a check payable to its order in the dollar amount equal to the Employment Taxes required to
be withheld with respect to those Shares.

Except  as  otherwise  provided  in  Paragraph  5,  the  settlement  of  all  Restricted
Stock Units which vest under the Awar d shall be made solely in shares of Common Stock.  In no event, however, shall
any fractional shares be issued.  Accordingly, the total number

(e)

-4-

 
 
 
 
of shares of Common Stock to be issued pursuant to the Award shall, to the extent necessary, be rounded down to t
next whole share in order to avoid the issuance of a fractional share.

8.

Compliance  with  Laws  and  Regulations .    The  issuance  of  shares  of  Common  Stock
pursuant  to  the  Award  shall  be  subject  to  compliance  by  the  Corporation  and  the  Participant  with  all  applicable
requirements of law relating thereto and with all applicable regulations of any stock exchange on which the Common
Stock may be listed for trading at the time of such issuance.

9.

of this Agreement shall be in writing and addressed to the Corporation at its principal corporate offices.  Except to the
extent  electronic  notice  is  expressly  authorized  hereunder,  any  notice  required  to  be  given  or  delivered  to  the
Participant shall be in writing and addressed to the Participant at the address indicated below the Participant’s signature

Participant any right to continue in Service for any period of specific duration or interfere with or otherwise restrict in
any  way  the  rights  of  the  Corporation  (or  any  Parent  or  Subsidiary  employing  or  retaining  the  Participant)  or  of  the
Participant, which rights are hereby expressly reserved by each, to terminate the Participant’s Service at any time for

under applicable law from any court having jurisdiction over the parties and the subject matter of their dispute relating
to their obligations under this letter agreement or under the Proprietary Information, Invention and Materials
Agreement before arbitration or while arbitration is pending.

Termination Date, and you pay the full monthly COBRA premium cost for such health coverage, the
Company shall reimburse you monthly an amount equal to the monthly COBRA premium paid by you, less
the premium charge that is paid by the Company’s active employees for such coverage as in effect on the
Termination Date (the “COBRA Reimbursement”).  The payments shall commence on the first payroll date
that is administratively practicable after the Effective Date (and within 30 days after the Termination
Date).  The first payment shall include any payments for the period from the Termination Date to the
commencement date.  The Company shall reimburse you under this subsection only for the portion of the
Coverage Period during which you continue coverage under the Company’s health plan.  You agree to
promptly notify the Company of your coverage under an alternative health plan upon becoming covered by
such alternative plan.  The COBRA health care continuation coverage period under section 4980B of the
Code shall run concurrently with the Coverage Period.  Notwithstanding the foregoing, the Company
reserves the right to restructure the foregoing COBRA premium reimbursement arrangement in any manner
necessary or appropriate to avoid fines, penalties or negative tax consequences to the Company or you
(including, without limitation, to avoid any penalty imposed for violation of the nondiscrimination
requirements under the Patient Protection and Affordable Care Act or the guidance issued thereunder), as
determined by the Company

in its sole and absolute discretion, including treating such reimbursements as taxable benefits subject to
withholding.

or claim that the rentable square footage of the Premises is other than as set forth in this Lease.

4.

Rent; Abatement of Rent.

(a)

Rent.  Commencing on the Commencement Date, subject to Section 4(b) below, Tenant shall timely pay to Landlord as Rent, (i) Base Rent as set
forth in the Basic Lease Information (subject to Section 4(b) below), and (ii) Additional Rent (as defined in Exhibit C) as set forth in Exhibit C hereto, without notice, demand, deduction or set-off (except as
otherwise  expressly  provided  herein),  by  good  and  sufficient  check  drawn  on  a  national  banking  association  at  Landlord’s  address  provided  for  in  this  Lease  or  electronically  via  automatic  debit  or  wire
transfer  to  such  account  as Landlord  designates  in  writing  to  Tenant,  or  as  otherwise  specified  in  writing  by  Landlord.    The  obligations  of  Tenant  to  pay  Base  Rent  and  other  sums  to  Landlord  and  the
obligations of Landlord under this Lease are independent obligations.  Base Rent shall be payable monthly in advance.  The first (1st) monthly installment of Base Rent shall be payable contemporaneously
with the execution of this Lease; thereafter, Base Rent shall be payable on the first (1st) day of each month beginning on the first (1st) day of the second (2nd) full calendar month of the Term, subject to
Section 4(b) below.  The monthly Base Rent for any partial month at the beginning of the Term shall equal the product of 1/365 of the annual Base Rent in effect during the partial month and the number of
days  in  the  partial  month,  and  shall  be  due  on  the  Commencement  Date.    Payments  of  Base  Rent  for  any  fractional  calendar  month  at  the  end  of  the  Term  shall  be  similarly  prorated.    Tenant  shall  pay
Additional Rent at the same time and in the same manner as Base Rent.

(b)

Abatement of Rent.    Notwithstanding  anything  to  the  contrary  contained  in  this  Lease, and  provided  that  no  Event  of  Default  exists,  Landlord
hereby agrees to abate Tenant’s obligation to pay Tenant’s monthly Base Rent (the “ Abated Rent”) by (i) 100% for the second (2nd) full calendar month through and including the tenth (10th) Lease Month,
and (ii) by 50% for the eleventh (11th) Lease Month through and including the sixteenth (16th) Lease Month (the “Abatement Period”).  During the Abatement Period, Tenant shall remain responsible for the
payment of all of its other monetary obligations under this Lease.  If during the Abatement Period an Event of Default (as defined in Section 17 below) occurs, and Landlord does not elect to terminate this
Lease in accordance with Article 18 below, then the Abated Rent shall reinstate for the remaining Abatement Period as of the date Tenant cures such Event of Default.  If at any time during the Term, an Event
of Default by Tenant occurs, and Landlord does elect to terminate this Lease in accordance with  Article 18 below, then as a part of the recovery set forth in Article 18, Landlord shall be entitled to the recovery
of that portion of the unamortized Abated Rent (which Abated Rent shall be amortized on a straight-line basis over the initial Lease Term).

5.

Delinquent  Payment;  Handling  Charges.   All  past  due  payments  required  of  Tenant  hereunder  shall  bear  interest  from  the  date  that  is  three  (3)  Business  Days  after
Landlord’s written notice thereof until paid at the lesser of ten percent (10%) per annum or the maximum lawful rate of interest (such lesser amount is referred to herein as the “Default Rate”); additionally,
Landlord, in addition to all other rights and remedies available to it, may charge Tenant a fee equal to five percent (5%) of the delinquent payment (the “ Late Charge”) to reimburse Landlord for its cost and
inconvenience incurred as a consequence of Tenant’s delinquency.  In no event, however, shall the charges permitted under this  Section 5 or elsewhere in this Lease, to the extent they are considered to be
interest under applicable Law,

151177627 v8

2

 
 
exceed the maximum lawful rate of interest.  Notwithstanding the foregoing, Landlord shall waive the accrual of the Default Rate and the payment the Late Charge once in any given twelve (12) month period.

6.

Letter of Credit.  Tenant shall deliver to Landlord, upon Tenant’s execution of this Lease, a Letter of Credit (as hereinafter defined) in the amount specified in the Basic
Lease Information, as additional security for the faithful performance and observance by Tenant of the terms, covenants and conditions of this Lease.  The Letter of Credit shall be in the form of a clean,
irrevocable, non-documentary and unconditional letter of credit (the “Letter of Credit”) which is attached hereto as Exhibit L, issued by and drawable upon Wells Fargo Bank, N.A. (the “Issuing Bank”).  If
upon any transfer of the Letter of Credit, any fees or charges shall be so imposed, then such fees or charges shall be payable solely by Tenant and the Letter of Credit shall so specify.  The Letter of Credit
shall provide that it shall be deemed automatically renewed, without amendment, for consecutive periods of one year each thereafter during the Term (and in no event shall the Letter of Credit expire prior to
the forty-fifth (45th) day following the Expiration Date) unless the Issuing Bank sends duplicate notices (the “Non-Renewal Notices”) to Landlord by certified mail, return receipt requested (one of which
shall be addressed “Attention, Chief Legal Officer” and the other of which shall be addressed “Attention, Chief Financial Officer”), not less than forty-five (45) days next preceding the then expiration date of
the Letter of Credit stating that the Issuing Bank has elected not to renew the Letter of Credit.  The Issuing Bank shall agree with all drawers, endorsers and bona fide holders that drafts drawn under and in
compliance with the terms of the Letter of Credit will be duly honored upon presentation to the Issuing Bank at an office location in Los Angeles, California.  The Letter of Credit shall be subject in all
respects to the International Standby Practices 1998, International Chamber of Commerce Publication No. 590.

(a)

Application of Security.  If (a) an Event of Default by Tenant occurs in the payment or performance of any of the terms, covenants or conditions of
this Lease, including the payment of Rent, or (b) Tenant fails to make any installment of Rent as and when due beyond an applicable notice and cure period, or (c) Landlord receives a Non-Renewal Notice,
Landlord shall have the right by sight draft to draw, at its election, all or a portion of the proceeds of the Letter of Credit and thereafter hold, use, apply, or retain the whole or any part of such proceeds, as the
case may be, (x) to the extent required for the payment of any Rent or any other sum as to which Tenant is in default including (i) any sum which Landlord may expend or may be required to expend by reason
of Tenant’s Event of Default, and/or (ii) any damages to which Landlord is entitled pursuant to this Lease, whether such damages accrue before or after summary proceedings or other reentry by Landlord,
and/or (y) as a cash security deposit, unless and until, in the case of clause (c) above, Tenant delivers to Landlord a substitute Letter of Credit which meets the requirements of this  Section 6.  If Landlord
applies or retains any part of the proceeds of the Letter of Credit, or cash security, Tenant, within five (5) Business Days  upon written demand, shall deposit with Landlord the amount so applied or retained so
that Landlord shall have the full amount thereof on hand at all times during the Term.  If Tenant shall comply with all of the terms, covenants and conditions of this Lease, the Letter of Credit or cash security,
as the case may be, shall be returned to Tenant within thirty (30) days after the Expiration Date and after delivery of possession of the Premises to Landlord in the manner required by this Lease.

(b)

Transfer.  Upon a sale or other transfer of the Building, or any financing of Landlord’s interest therein, Landlord shall have the right to transfer the
Letter of Credit or the cash security to its transferee or lender. With respect to the Letter of Credit, within ten (10) Business Days after notice of such transfer or financing, Tenant, at its sole cost, shall arrange
for the transfer of the Letter of Credit to the new landlord or the lender, as designated in writing by Landlord in the foregoing notice or have the Letter of Credit reissued in the name of the new landlord or the
lender.    Upon  such  transfer,  Tenant  shall  look  solely  to  the  new  landlord  or  lender  for  the  return  of  the  Letter  of  Credit  or  such  cash  security;  provided  that  such  new  landlord  has  assumed  Landlord’s
obligations hereunder and the provisions hereof shall apply to every transfer or assignment made of the Letter of Credit or such cash security to a new landlord.  Tenant shall not assign or encumber or attempt
to assign or encumber the Letter of Credit or such cash security and

151177627 v8

neither Landlord nor its successors or assigns shall be bound by any such action or attempted assignment, or encumbrance.

(c)

Reduction of Letter of Credit.  Effective as of the date the Reduction Conditions (as hereinafter defined) are satisfied, the amount of the Letter of
Credit shall be reduced to an amount equal to One Million Five Hundred Thousand Dollars ($1,500,000.00).  For purposes of this Section 6(c), the “Reduction Conditions” shall mean (i) Tenant shall have
received a Certificate of Occupancy for the Premises and provided Landlord with a copy thereof, and (ii) Tenant shall have raised Two Hundred Million Dollars ($200,000,000.00) as evidenced by a Security
Exchange Commission regulatory filing reflecting an increase in equity of Tenant by Two Hundred Million Dollars ($200,000,000.00) as compared with Tenant’s audited financial statements for the calendar
year ending 2016.  There shall be no reduction of the Letter of Credit as set forth herein if, at the time of such reduction, an Event of Default exists under this Lease.

7.

Services; Utilities; Common Areas.

Services.  Other than Landlord’s maintenance obligations expressly set forth in this Lease, Landlord shall not be obligated to provide any services
to Tenant, provided that Landlord shall as part of Common Area Maintenance Costs provide electric lighting for all Common Area (including parking area) as Landlord reasonably determines to be standard,
including replacement of Building standard lights, bulbs and tubes.

(a)

(b)

Utility Use.   Tenant  shall  obtain  all  water,  electricity,  sewage,  gas,  telephone  and  other  utilities  for  the  Premises  directly  from  the  public  utility
company furnishing same.  Any meters or modifications thereof required in connection therewith shall be installed at Tenant’s sole cost.  Tenant shall pay all utility deposits and fees, and all monthly service
charges for water, electricity, sewage, gas, telephone and any other utility services furnished to the Premises during the Term of this Lease.  Tenant shall not inst all any equipment which exceeds or overloads
the capacity of the utility facilities serving the Premises.  Tenant agrees that Landlord shall not be liable for damages, by abatement of Rent or otherwise, for failure to furnish or delay in furnishing any
service, or for any diminution in the quality or quantity thereof, when such failure or delay or diminution is occasioned, in whole or in part, by breakage, repairs, replacements, or improvements, by act or
default of Tenant or other parties, by any Force Majeure Event (as defined in Section 26(c)), or by any other cause beyond Landlord’s reasonable control.  Notwithstanding the foregoing, in the event of an
interruption of utility service which (i) is the result of Landlord’s gross negligence or willful misconduct, (ii) continues for more than three (3) consecutive Business Days (“Eligibility Period”),  and  (iii)
renders the Premises unsuitable for Tenant’s normal business operations, and (iv) Tenant actually does not use the Premises or any portion thereof for three (3) consecutive Business Days, then Tenant’s Base
Rent shall be abated or reduced, as the case may be, after expiration of the Eligibility Period for such time that Tenant continues to be so prevented from using, and does not use, the Premises or a portion
thereof, in the proportion that the rentable area of the portion of the Premises that Tenant is prevented from using, and does not use, bears to the rentable area of the Premises.

Tenant hereby reserves the right, in connection with either its Tenant Improvement electrical tie-in work (pursuant to the terms and conditions of the Tenant
Work Letter) or due to applicable governmental code or agency required electrical systems testing, to reasonably shut down power to the Building for a limited time not to exceed four (4) hours per each shut-
down, except as otherwise provided in the MOP (as defined).  Tenant shall prepare a method of procedure (“MOP”) setting forth the specific terms and conditions of such action, including the specific time of
Building power shut-down and re‑start, for Landlord’s review and approval (which approval shall not be unreasonably withheld) no later than ten (10) business days prior to the anticipated date  of  shut-
down.  As long as Tenant complies with the terms and conditions of the MOP as approved by Landlord, Tenant shall not be liable for damages to the Cell Tower Equipment in connection with Tenant’s shut-
down as set forth herein.

(c)

Common Areas.  The term “Common Area” is defined for all purposes of this Lease as that part of the Project and/or Complex intended for the
common  use  of  all  tenants,  including  among  other  facilities  (as  such  may  be  applicable  to  the  Complex),  parking  areas,  private  streets  and  alleys,  landscaping,  curbs,  loading  areas,  sidewalks,  lighting
facilities, drinking fountains, meeting rooms, public toilets, and the like, but excluding:  (i) space in other buildings (now or hereafter existing) in the Complex designated for rental for commercial purposes, as
the same may exist from time to time; (ii) streets and alleys maintained by a public authority; (iii) areas within the Complex which may from time to time not be owned by Landlord (unless subject to a cross-
access or common use agreement benefiting the area which includes the Premises); and (iv) areas leased to a single-purpose user where access is restricted.  Landlord reserves the right to change from time to
time the dimensions and location of the Common Area, as well as the dimensions, identities, locations and types of any buildings, signs or other improvements in the Complex, so long as (y) access to the
Premises and/or  the  parking  area,  or  (z)  the  size  or  access  to  the  Premises  and/or  the  parking  area is  not  materially  adversely  affected  thereby.    For  example,  and  without  limiting  the  generality  of  the
immediately preceding sentence, Landlord shall have no right to move the parking area from the Complex.  Tenant, and its employees and customers, and when duly authorized pursuant to the provisions of
this Lease, its subtenants, licensees and concessionaires, shall have the non-exclusive right to use the parking spaces (designated in the Basic Lease Information) in the Common Area (excluding roof(s)) as
constituted from time to time) and right to designate visitor parking spaces within the parking area of the Complex (and the number of visitor parking spaces shall be deducted from the overall two hundred
seventy-eight  (278)  undesignated  parking  spaces  provided  to  Tenant),  such  use  to  be  in  common  with  Landlord,  other  tenants  in  the  Building  (if  any) and/or  Complex,  as  applicable,  and  other  persons
permitted by the Landlord to use the same, and subject to rights of governmental authorities, easements, other restrictions of record, and such reasonable rules and regulations governing use as Landlord may
from time to time prescribe subject to Section 13 hereof.  For example, and without limiting the generality of Landlord’s ability to establish rules and regulations governing all aspects of the Common Area in
accordance with Section 13 hereof, Tenant agrees as follows:

Landlord may from time to time designate specific areas within the Project or Complex, as applicable, in which automobiles
owned by Tenant, its employees, subtenants, licensees, and concessionaires shall be parked; and Tenant agrees that if any automobile or other vehicle owned by Tenant or any of its employees, its subtenants,
its licensees or its concessionaires, or their employees, shall at any time be parked in any part of the Project or Complex, as applicable, other than the specified areas designated for employee parking, Landlord
may have such vehicle towed at the cost of the owner of same.

(i)

other persons to use the Common Area.

(ii)

(iii)

Tenant  shall  not  solicit  business  within  the  Common Area  nor  take  any  action  which  would  interfere  with  the  rights  of

Landlord may temporarily close any part of the Common Area for such periods of time as may be reasonably necessary to

make repairs or alterations or to prevent the public from obtaining prescriptive rights, so long as access to the Premises and/or the parking area is not materially adversely affected thereby.

8.

Alterations; Repairs; Maintenance; Signs.

(a)

Alterations.  Except for Tenant Improvements and Cosmetic Changes (as hereinafter defined), Tenant shall not make any alterations, additions or
improvements  to  the  Premises  (collectively,  the  “ Alterations”)  without  the  prior  written  consent  of  Landlord,  which  consent  shall  not  be  unreasonably  withheld,  conditioned  or  delayed,  except  for  the
installation of unattached, movable trade fixtures which may be installed without drilling, cutting or otherwise defacing the Premises. Notwithstanding the foregoing, Tenant shall not be obligated to receive
the written consent of Landlord for interior Alterations to the Premises (i) where the estimated cost of the proposed Alteration is Seventy-Five Thousand Dollars ($75,000.00) or less in any twelve (12) month
period, (ii) if said Alterations do not affect the structural components of the Building, or adversely affect the Building’s Systems or which can be seen

151177627 v8

5

 
 
from outside the Premises, and (iii) if said Alteration shall not require a building permit or any federal, state, county or local approvals (the “Cosmetic Changes”).  Tenant shall furnish complete plans and
specifications to Landlord for its approval, which approval shall not be unreasonably withheld, conditioned or delayed, at the time it requests Landlord’s consent to any Alterations, if the desired Alterations:
(i) will affect the Building’s Systems or Building’s Structure; or (ii) will require the filing of plan s and specifications with any governmental or quasi-governmental agency or authority; or (iii) will require a
building permit or other federal, state, county or local approvals with respect thereto.  Landlord shall either approve or disapprove Tenant’s pro posed Alteration within five (5) business days of Landlord’s
receipt of Tenant’s request and Tenant’s plans and specifications with respect to such proposed Alteration.  Subsequent to obtaining Landlord’s consent and prior to commencement of the Alteration s, Tenant
shall deliver to Landlord any building permit required by applicable Law and a copy of the executed construction contract(s).  Tenant shall reimburse Landlord within ten (10) days after the rendition of a bill
for  all  of  Landlord’s  actual and reasonable out-of-pocket  costs  incurred  in  connection  with  any Alterations  (excluding  Cosmetic  Changes),  including  all  management,  engineering,  outside  consulting,  and
construction fees incurred by or on behalf of Landlord for the review and approval of Tenant’s plans and specifications and for the monitoring of construction of the Alterations, together with a supervision
coordination fee to Landlord in an amount equal to the product of (i) three percent (3%) and (ii) the costs of the Alterations.  If Landlord consents to the making of any Alteration, such Alteration shall be made
by  Tenant  at  Tenant’s  sole  cost  and  expense  by  contractors  and  subcontractors  approved  in  writing  by  Landlord  in  accordance  with  Section 8(b)(iii),  which  approval  shall  not  unreasonably  be  withheld,
conditioned or delayed.  Without Landlord’s prior written consent, Tenant shall not use any portion of the Common Areas either within or outside the Project or Complex, as applicable, in connection with the
making of any Alterations.  If the Alterations which Tenant causes to be constructed result in Landlord being required to make any alterations and/or improvements to other portions of the Project or Complex,
as applicable, in order to comply with any applicable Laws (provided that such alterations and/or improvements are necessitated solely due to Tenant’s Alterations, and in no event are caused by any violations
or  non-compliance  with  applicable  Laws  which  existed  on  the  Delivery  Date),  then  Tenant  shall  reimburse  Landlord  within  thirty  (30)  days  upon  written  demand  for  all  costs  and  expenses  actually  and
reasonably incurred by Landlord in making such alterations and/or improvements in the Project or Complex, as applicable.  Any Alterations made by Tenant shall become the property of Landl ord upon the
expiration or sooner termination of this Lease and shall remain on and be surrendered with the Premises upon the expiration or sooner termination of this Lease, except Tenant shall, upon written demand by
Landlord, at Tenant’s sole cost and ex pense, forthwith and with all due diligence (but in any event not later than ten (10) days after the expiration or earlier termination of the Lease) remove all or any portion
of any Alterations made by Tenant which are designated by Landlord in writing to  be removed (the “Removal Notice”) at the time of Landlord’s consent to such Alterations (including without limitation
stairs, bank vaults, and cabling, movable laboratory casework and related appliances, built-in cabinet work and paneling, sinks and related plumbing fixtures, laboratory benches, exterior venting fume hoods
and walk-in freezers and refrigerators, if applicable) and repair any damages to the Premises caused by such removal in a good and workmanlike manner to their original condition, reasonable wear and tear
and Casualty not required to be repaired by Tenant excepted. All construction work done by Tenant within the Premises shall be performed in a good and workmanlike manner with new materials of first-class
quality, lien-free and in compliance with all applicable Laws, and in such manner as to cause a minimum of interference with other construction in progress and with the transaction of business in the Project or
Complex, as applicable.  TENANT AGREES TO INDEMNIFY, DEFEND AND HOLD LANDLORD HARMLESS AGAINST ANY LOSS, LIABILITY OR DAMAGE RESULTING FROM SUCH
WORK  EXCEPT  TO  THE  EXTENT ANY  SUCH  LOSS,  LIABILITY  OR  DAMAGE  IS  CAUSED  BY  THE  GROSS  NEGLIGENCE  OR  WILLFUL  MISCONDUCT  OF  LANDLORD AND
FURTHER  SUBJECT  TO  THE  MUTUAL  WAIVERS  OF  SUBROGATION  HEREI NAFTER  SET  FORTH  IN SECTION 11(d), AND  TENANT  SHALL,  IF  REQUESTED  BY  LANDLORD,
FURNISH A BOND OR OTHER SECURITY REASONABLY SATISFACTORY TO LANDLORD AGAINST ANY SUCH LOSS,

151177627 v8

6

 
 
LIABILITY OR DAMAGE; provided, however, that no bond shall be required in connection with any Cosmetic Changes.  The foregoing indemnity shall survive the expiration or earlier termination of this
Lease.  Landlord’s consent to or approval of any Alterations, additions or improvements (or the plans therefor) shall not constitute a representation or warranty by Landlord, nor Landlord’s acceptance, that the
same comply with sound architectural and/or engineering practices or with all applicable Laws, and Tenant shall be solely responsible for ensuring all such compliance.

(b)

Repairs; Maintenance.

(i)

By Landlord.  Landlord shall, subject to reimbursement under Exhibit C (to the extent such costs are reimbursable therein),
keep the Building’s Structure in good repair and working condition.  Notwithstanding anything to the contrary contained in this Lease, any defects in design or construction of the Base, Shell and Core shall
be corrected by Landlord at Landlord’s sole cost.  Landlord, however, shall not be required to make any repairs occasioned by the act or negligence of Tenant, its agents, contracto rs, employees, subtenants,
licensees and concessionaires (including, but not limited to, roof leaks resulting from Tenant’s installation of air conditioning equipment or any other new roof penetration or placement); and the provisions of
the previous sentence are expressly recognized to be subject to Sections 14 and 15 of this Lease.  In the event that the Premises should become in need of repairs required to be made by Landlord hereunder,
Tenant shall give immediate written notice thereof to Landlord, and Landlord shall have a reasonable time after receipt by Landlord of such written notice in which to make such repairs.  Landlord shall not be
liable to Tenant for any interruption of Tenant’s business or inconvenience caused due to any work performed in the  Premises or in the Complex pursuant to Landlord’s rights and obligations under the Lease,
provided, however, Landlord shall use commercially reasonable efforts to not disturb the normal conduct of Tenant’s business or Tenant’s access to the Premises and/or parking areas  while performing such
repairs and maintenance.  In addition, Landlord shall maintain the Common Areas of the Project or Complex, as applicable, in a manner consistent with first class office and biotech buildings in Brisbane,
California, subject to reimbursement as set forth in Exhibit C (to the extent such costs are reimbursable therein).  TENANT HEREBY WAIVES AND RELEASES ITS RIGHT TO MAKE REPAIRS AT
LANDLORD’S  EXPENSE  UNDER  SECTIONS  1941  AND  1942  OF  THE  CALIFORNIA  CIVIL  CODE  OR  UNDER  ANY  SIMILAR  LAW,  STATUTE  OR  ORDINANCE  NOW  OR
HEREAFTER IN EFFECT.

(ii)

By  Tenant.   Tenant  shall  keep  the  Premises  (other  than  those  portions  required  to  be  maintained  by  Landlord  under
Section 8(b)(i)  above), in good, clean and habitable condition, and shall at its sole cost and expense keep the same free of dirt, rubbish, ice or snow, insects, rodents, vermin and other pests and make all
needed repairs and replacements, including replacement of cracked or broken glass, except for repairs and replacements required to be made by Landlord, and any damage caused by ordinary wear and tear or
Casualty.    Without  limiting  the  coverage  of  the  previous  sentence,  it  is  understood  that  Tenant’s  responsibilities  therein  include  the  repair  and  replacement  in  accordance  with  all  a pplicable  Laws  of  the
Building’s Systems, including the lighting, heating, air conditioning, life-safety, plumbing and other electrical, mechanical and electromotive installation, equipment and fixtures and also include all utility
repairs in ducts, conduits, pipes and wiring, and any sewer stoppage located in, under and above the Premises. All contractors and subcontractors may be subject to Landlord’s written approval in accordance
with Section 8(b)(iii).  If any repairs required to be made by Tenant hereunder are not commenced within thirty (30) days (such time period not being subject to the notice and cure provisions of Section 17(f))
after written notice delivered to Tenant by Landlord (which shall be given at its reasonable discretion) or are not diligently executed to completion with Tenant using commercially reasonable efforts given the
circumstances, Landlord may at its option make such repairs without liability to Tenant for any loss or damage which may result to its stock or business by reason of such repairs, unless caused by the gross
negligence or willful misconduct of Landlord, its employees, agents or contractors, provided that Landlord shall use commercially reasonable efforts to minimize interference with Tenant’s use of, or access
to, the Premises.  Tenant shall pay to Landlord within ten (10) days upon written demand as Rent hereunder,

151177627 v8

7

 
 
the cost of such repairs plus interest at the Default Rate, such interest to accrue continuously from the date of payment by Landlord until repayment by Tenant.  Notwithstanding the foregoing, Landlord shall
have the right to make such repairs without notice to Tenant in the event of an emergency, or if such repairs relate to the exterior of the Premises.  At the expiration  or earlier termination of this Lease, Tenant
shall surrender the Premises in as good a condition as existed on the date the Tenant Improvements are substantially completed, excepting reasonable wear and tear and casualties not required to be repaired by
Tenant.  If Tenant elects to store any personal property of Tenant, including goods, wares, merchandise, inventory, trade fixtures and other personal property of Tenant, same shall be stored at the sole risk of
Tenant.  Unless caused by the gross negligence or willful misconduct of Landlord, its employees, agents or contractors, Landlord and its agents shall not be liable for any loss or damage to persons or property
resulting from fire, explosion, falling plaster, steam, gas, electricity, water or rain which may leak from any part of the Complex or from the pipes, appliances or plumbing works therein or from the roof, street
or subsurface or from any other places resulting from dampness or any other cause whatsoever, or from the act or negligence of any other tenant or any officer, agent, emplo yee, contractor or guest of any
such tenant.  It is generally understood that mold spores are present essentially everywhere and that mold can grow in most any moist location.  Emphasis is properly placed on prevention of moisture and on
good  housekeeping and  ventilation  practices.    Tenant  acknowledges  the  necessity  of  housekeeping,  ventilation,  and  moisture  control  (especially  in  kitchens,  janitor’s  closets,  bathrooms,  break  rooms  and
around outside walls) for mold prevention.  In signing this Lease, Tenan t has first inspected the Premises and certifies that it has not observed mold, mildew or moisture within the Premises.  Tenant agrees to
immediately notify Landlord if it observes mold/mildew and/or moisture conditions (from any source, including leaks), and allow Landlord to evaluate and make recommendations and/or take appropriate
corrective  action.  TENANT  RELIEVES  LANDLORD  FROM  ANY  LIABILITY  FOR  ANY  BODILY  INJURY  OR  DAMAGES  TO  PROPERTY  CAUSED  BY  OR  ASSOCIATED  WITH
MOISTURE OR THE GROWTH OF OR OCCURRENCE OF MOLD OR MILDEW ON THE PREMISES, UNLESS SAME IS IN EXISTENCE ON THE DELIVERY DATE OR IS CAUSED
BY  THE GROSS NEGLIGENCE  OR  WILLFUL  MISCONDUCT  OF  LANDLORD,  ITS  EMPLOYEES,  AGENTS  OR  CONTRACTORS.    In  addition,  execution  of  this  Lease  constitutes
acknowledgement by Tenant that control of moisture and mold prevention are integral to its Lease obligations.

Notwithstanding Tenant’s repair and maintenance obligations pursuant to this Section 8(b)(ii), if any item of Tenant’s repair and maintenance
obligations set forth herein involves a capital repair, replacement, improvement and/or equipment under generally accepted accounting principles consistently applied (“Tenant Repair Capital Item”), Tenant
shall provide written notice thereof to Landlord.  Landlord shall, pursuant to the receipt of such notice from Tenant, make such Tenant Repair Capital Item in a manner such that the Tenant Repair Capital Item
to be completed by Landlord shall be similar in size, scope and specifications as the item so repaired by Landlord.  Landlord and Tenant shall use their respective commercially reasonable efforts to discuss
and come to a mutually acceptable agreement with respect to the size, scope and specifications of the Tenant Repair Capital Item; provided, however, that in no event shall the size, scope and specifications of
such Tenant Repair Capital Item exceed the original size, scope and specifications of the item subject to the repair.  Following completion of the Tenant Repair Capital Item, Landlord shall provide Tenant
with written notice of (i) the total cost of such Tenant Repair Capital Item (“Tenant Repair Capital Item Cost”),  (ii)  the  estimated  useful  life  of  such  Tenant  Repair  Capital  Item  per  generally  accepted
accounting principles consistently applied (“Useful Life”), (iii) the amortization of such Tenant Repair Capital Item Cost over such Useful Life at an interest rate equal to the “prime rate” as announced from
time to time by Bank of America, N.A., plus one percent (1%) per annum, and (iv) the monthly amount due and payable by Tenant to reimburse Landlord for that portion of the amortized Tenant Repair
Capital Item Cost applicable to the remainder of the Lease Term, which monthly amount shall be paid by Tenant to Landlord concurrently with the payment by Tenant to Landlord of the monthly Base Rent.

151177627 v8

(iii)

Performance of Work.  All work described in this Section 8 which affects the Building’s Structure and/or the Building’s
Systems  shall  be  performed  only  by  contractors  and  subcontractors  approved  in  writing  by  Landlord,  which  approval  shall  not  be  unreasonably  withheld,  conditioned  or  delayed  (which  approval  or
disapproval shall be provided by Landlord within three (3) business days of Landlord’s receipt of the identity of the applicable contractor and subcontractor).  Landlord hereby acknowledges and agrees that
Tenant’s contractors and subcontractors approved by Landlord in connection with the design and construction of the Tenant Improvements shall be deemed to be approved in connection with Tenant’s work in
this Section 8.    Tenant  shall  cause  all  contractors  and  subcontractors  to  procure  and  maintain  insurance  coverage  naming  Landlord  and  Landlord’s  property  management  company  as  additional  insureds
against such risks, in such amounts, on such forms, and with such companies as Landlord may reasonably require as set forth on Exhibit I attached hereto.  Tenant shall provide Landlord with the identities,
mailing  addresses  and  telephone  numbers  of  all  persons  performing  work  or  supplying  materials  prior  to  beginning  such  construction  and  Landlord  may  post  on  and  about  the  Premises  notices  of  non-
responsibility pursuant to applicable Laws.  All such work shall be performed in accordance with all applicable Laws and in a good and workmanlike manner so as not to damage the Building (including the
Premises, the Building’s Structure and the Building’s Systems).  All such wo rk which may affect the Building’s Structure or the Building’s Systems, at Landlord’s election, must be performed by Landlord’s
usual  contractor  for  such  work  or  a  contractor  approved  by  Landlord,  which  approval  shall  not  be  unreasonably  withheld,  conditioned  or  delayed.   All  work  affecting  the  roof  of  the  Building  must  be
performed by Landlord’s roofing contractor or a contractor approved by Landlord, which approval shall not be unreasonably withheld, conditioned or delayed, and no such work will be permitted if it would
void or reduce the warranty on the roof.  

(c)

Mechanic’s  Liens.   All  work  performed,  materials  furnished,  or  obligations  incurred  by  or  at  the  request  of  a  Tenant  Party  shall  be  deemed
authorized and ordered by Tenant only, and Tenant shall not permit any mechanic’s liens to be filed against the Premises or the Project in connection therewith.  Upon completion of any such work, Tenant
shall deliver to Landlord final lien waivers from all contractors, subcontractors and materialmen who performed such work.  If such a lien is filed, then Tenant shall, within thirty (30) days after Landlord has
delivered notice of the filing thereof to Tenant (or such earlier time period as may be necessary to prevent the forfeiture of the Premises, Project or any interest of Landlord therein or the imposition of a civil or
criminal fine with respect thereto), either: (1) pay the amount of the lien and cause the lien to be released of record; or (2) diligently contest such lien and deliver to Landlord a bond or other security reasonably
satisfactory to Landlord.  If Tenant fails to timely take either such action, then Landlord may pay the lien claim, and any amounts so paid, including expenses and interest, shall be paid by Tenant to Landlord
within thirty (30) days after Landlord has invoiced Tenant therefor.  Landlord and Tenant acknowledge and agree that their relationship is and shall be solely that of “landlord-tenant” (thereby excluding a
relationship of “owner-contractor,” “owner-agent” or other similar relationships).  Accordingly, all materialmen, contractors, artisans, mechanics, laborers and any other persons now or hereafter contracting
with Tenant, any contractor or subcontractor of Tenant or any other Tenant Party for the furnishing of any labor, services, materials, supplies or equipment with respect to any portion of the Premises, at any
time from the date hereof until the end of the Term, are hereby charged with notice that they look exclusively to Tenant to obtain payment for same.  Nothing herein shall be deemed a consent by Landlord to
any liens being placed upon the Premises, Project or Landlord’s interest therein due to any work performed by or for Tenant or deemed to give any contractor or subcontractor or materialman any right or
interest  in  any  funds  held  by  Landlord  to  reimburse  Tenant  for  any  portion  of  the  cost  of  such  work.  TENANT  SHALL  INDEMNIFY,  DEFEND  AND  HOLD  HARMLESS  LANDLORD,  ITS
PROPERTY  MANAGER,  ANY  SUBSIDIARY  OR  AFFILIATE  OF  THE  FOREGOING,  AND  THEIR  RESPECTIVE  OFFICERS,  DIRECTORS,  SHARE-HOLDERS,  PARTNERS,
EMPLOYEES, MANAGERS, CONTRACTORS, ATTORNEYS AND AGENTS (COLLECTIVELY, THE  “INDEMNITEES”) FROM AND AGAINST ALL CLAIMS, DEMANDS, CAUSES OF
ACTION, SUITS, JUDGMENTS, DAMAGES AND EXPENSES (INCLUDING

151177627 v8

9

 
 
REASONABLE  ATTORNEYS’  FEES)  IN  ANY  WAY   ARISING  FROM  OR  RELATING  TO  THE  FAILURE  BY  ANY  TENANT  PARTY  TO  PAY  FOR  ANY  WORK  PERFORMED,
MATERIALS FURNISHED, OR OBLIGATIONS INCURRED BY OR AT THE REQUEST OF A TENANT PARTY. The foregoing indemnity shall survive termination or expiration of this Lease.

(d)

Signs.

(i)

General Signs.   Tenant  shall  have  the  right  to  place  any  signs  in,  on  or  around  the  Building  so  long  as  (x)  such  sign
complies with applicable Law, and Tenant shall have received any applicable governmental permit, and (y) Tenant shall have provided Landlord with notice thereof and a copy of any applicable governmental
permit(s).  Upon request of Landlord, Tenant shall immediately remove any sign or other materials which Tenant has placed or permitted to be placed upon the exterior or interior surfa ce of any door or
window inside the Premises, or the exterior of the Building, if required in connection with any repairs to the Building.  If Tenant fails to do so, Landlord may without liability unless caused by the gross
negligence or willful misconduct of Landlord, its employees, agents or contractors, remove the same at Tenant’s expense.  Tenant shall comply with such regulations as may from time to time be promulgated
by Landlord and provided to Tenant in writing governing signs, advertising material or lettering of all tenants in the Project or Complex, as applicable.  Tenant shall be responsible for the repair, painting or
replacement of the Building fascia surface or other portion of the Building where signs are attached and/or any damage to the Premises to remove signs placed by Tenant, upon vacation of the Premises, or the
removal or alteration of its sign for any reason.  If Tenant fails to do so, Landlord may have the sign removed and the reasonable cost of removal shall be payable by Tenant within thirty (30) days of invoice.

(ii)

Building  Top  Sign(s).    Subject  to  the  terms  of  this Section 8  and  applicable  Laws,  Landlord  hereby  grants  Tenant  the
right,  at  Tenant’s  sole  cost  and  expense,  to  install  up  to  two  (2)  Building  top  signs  at  location(s)  elected  by  Tenant  (which  may  include  both  Tenant’s  name,  which  shall  be  restricted  to  only  Sangamo
Therapeutics, Inc. and corporate logo) (“Building Top Sign(s)”).  Tenant’s Building Top Sign(s) shall be subject to all applicable Laws and Tenant’s receipt of any applicable governmental permit(s).  The
content,  size,  design,  graphics,  materials,  colors  and  other  specifications  of  the  Building  Top  Sign(s)  (including  without  limitation,  the  exact  location  of  any  and  all  of  the  Building  Top  Sign(s))  shall  be
consistent with the exterior design, materials and appearance of the Building and the signage program of the Building, if any.  The contractors and/or subcontractors utilized by Tenant in connection with the
Building  Top  Sign(s)  may  be  subject  to  Landlord’s  written  approval  in  accordance  with  Section 8(b)(iii).    Tenant  shall  be  responsible  for  all  costs  and  expenses  incurred  in  connection  with  the  design,
construction,  installation,  repair,  operation,  maintenance,  compliance  with  laws,  utilities  (including  the  costs  of  metering  such  utilities  usage  and  the  cost  of  the  meter)  and  removal  of  the  Building  Top
Sign(s).  Tenant shall also be responsible for the cost of all utilities (if any) utilized in connection with the Building Top Sign(s).  Tenant’s signage rights set forth in this Section 8(d)(ii) shall be personal to the
Tenant and may not be assigned to any assignee or any sublessee or any other person or entity (except in connection with a Permitted Transferee).  Should the name of Tenant be changed to another name (the
“New Name”),  Tenant  shall  be  entitled  to  modify,  at  Tenant’s  sole  cost  and  expense,  Tenant’s  name  on  the  Building  Top  Sign(s)  to  reflect  Tenant’s  New  Name,  so  long  as  (a)  the  New  Name  is  not  an
“Objectionable Name”, (b) Landlord shall have granted its consent to such New Name (which consent Landlord may withhold in its sole and absolute discretion), (c) Tenant’s New Name shall be subject to
the then existing signage rights of any tenant or occupant within the Complex, (d) Tenant’s New Name shall not cause Landlord to be in violation of another lease or agreement which Landlord is a party at the
Complex, and (e) Tenant’s New Name shall not cause Landlord to be in violation of an exclusivity granted to another tenant at the Complex.  The term “ Objectionable Name” shall mean any name which
relates to an entity which is of a character or reputation, or is associated with a political orientation or faction, which is inconsistent with the quality of the Complex, or which would otherwise reasonably
offend a landlord of buildings comparable to and in the vicinity of the Building.  In addition, Tenant’s right to maintain any of the Building Top Sign(s) shall

151177627 v8

terminate at any time during the Lease Term during the continuance of an Event of Default under this Lease.  Upon the expiration of the Lease Term or the earlier termination of Tenant’s signage rights under
this Section 8(d)(ii), Tenant shall, at Tenant’s sole cost and expense, remove the Building Top Sign(s) and repair any and all damage to the Building caused by such removal.

9.

Use; Compliance with Laws.  Tenant shall use the Premises only for the Permitted Use (as set forth in the Basic Lease Information) and shall comply with all applicable
Laws relating to the use, condition, access to, and occupancy of the Premises and will not commit waste, overload the Building’s Structure or the Building’s Systems or subject the Premises to any use that
would damage the Premises (ordinary wear and tear excepted).  Tenant, at its sole cost and expense, shall obtain and keep in effect during the Term, all permits, licenses, and other authorizations necessary to
permit Tenant to use and occupy the Premises for the Permitted Use in accordance with applicable Laws.  Notwithstanding anything in this Lease to the contrary, as between Landlord and Tenant:  (i) Tenant
shall bear the risk of complying with Title III of the Americans With Disabilities Act of 1990, any state laws governing handicapped access or architectural barriers, and all rules, regulations, and guidelines
promulgated under such laws, as amended from time to time (the “Disabilities Acts”) with respect to the Premises (but not the Common Areas); and (ii) Landlord shall bear the risk of complying with the
Disabilities Acts in the Common Areas (subject to  Exhibit C), other than compliance that is necessitated by Tenant’s use of the Premises or as a result of the Tenant Improvements as defined on Exhibit D and
any Alterations made by Tenant (which risk and responsibility shall be borne by Tenant).  Landlord represents  and warrants that as of the Delivery Date, the Common Areas shall be in compliance with the
Disabilities Acts.  The Premises shall not be used for any purpose which releases outside the Premises strong, unusual, or offensive odors, fumes, dust or vapors which is objectionable to a typical person;
which emits outside the Premises noise or sounds that are objectionable to a typical person due to intermittence, beat, frequency, shrillness, or loudness; which is associated with indecent or pornographic
matters; or which involves political or moral issues (such as abortion issues).  Tenant shall conduct its business and control each other Tenant Party so as not to create any nuisance or unreasonably interfere
with other tenants of the Complex or Landlord in its management of the Building.  Tenant shall store all trash and garbage within the Premises or in a trash dumpster or similar container approved by Landlord
as to type, location and screening; and Tenant shall arrange for the regular pick-up of such trash and garbage at Tenant’s expense (unless Landlord finds it necessary to furnish such a service, in which event
Tenant shall be charged an equitable portion of the total of the charges to all tenants using the service).  Tenant shall not operate an incinerator or burn trash or garbage within the Project or Complex, as
applicable.  Tenant shall not knowingly conduct or permit to be conducted in the Premises any activity, or place any equipment in or about the Premises or the Building, which will invalidate the insurance
coverage in effect or increase the rate of fire insurance or other insurance on the Premises or the Building; provided that the Permitted Use will not be deemed to invalidate such insurance coverage or increase
the rate of such insurance on the Premises or the Building.  If any invalidation of coverage or increase in the rate of fire insurance or other insurance occurs or is threatened by any insurance company due to
activity conducted from the Premises in violation of this Lease, or any act or omission by Tenant, or its agents, employees, representatives, or contractors in violation of this Lease, such statement or threat
shall be conclusive evidence that the increase in such rate is due to such act of Tenant or the contents or equipment in or about the Premises, and, as a result thereof, Tenant shall be liable for such increase and
shall be considered Additional Rent payable with the next monthly installment of Base Rent due under this Lease.  In no event shall Tenant introduce or permit to be kept  on the Premises or brought into the
Building any dangerous, noxious, radioactive or explosive substance in violation of Section 25 herein.

10.

Assignment and Subletting.

Transfers.  Except for Permitted Transfers, Tenant shall not, without the prior written consent of Landlord, which consent shall not unreasonably
be  withheld,  conditioned  or  delayed:    (1)  assign,  transfer,  or  encumber  this  Lease  or  any  estate  or  interest  herein,  whether  directly  or  by  operation  of  law;  (2)  permit  any  other  entity  to  become  Tenant
hereunder by merger, consolidation, or other

(a)

151177627 v8

11

 
 
reorganization; (3) if Tenant is an entity other than  a  corporation  whose  stock  is  publicly  traded,  permit  the  transfer  of  an  ownership  interest  in  Tenant  so  as  to  result  in  a  change  in  the  current  control  of
Tenant; (4) sublet any portion of the Premises; (5) grant any license, concession, or other right of occupancy of any portion of the Premises; or (6) permit the use of the Premises by any parties other than
Tenant (any of the events listed in Section 10(a)(1) through Section 10(a)(6) being a “Transfer”).

(b)

Consent Standards.  If a proposed transferee does not meet the following conditions, Landlord shall not be deemed to have been unreasonable in
withholding its consent to a Transfer (provided that the following list shall not be deemed the exclusive factors for review):  (1) intentionally omitted; (2) has a good reputation in the business community;
(3) will use the Premises for the Permitted Use and will not use the Premises in any manner that would conflict with any exclusive use agreement or other similar agreement entered into by Landlord with any
other tenant of the Project or Complex, as applicable; (4) will not use the Premises, Project or Complex in a manner that would materially increase the pedestrian or vehicular traffic to the Premises, Project or
Complex; (5) is not another occupant of the Building or Complex, as applicable, and there is a comparable space available in the Complex at the time of Tenant’s request for Landlord’s consent ; and (6) is not
a person or entity with whom Landlord is then, or has been within the three-month period prior to the time Tenant seeks to enter into such assignment or subletting, negotiating to lease space in the Building or
Complex, as applicable, or any Affiliate of any such person or entity, and there is a comparable space available in the Complex at the time of Tenant’s request for Landlord’s consent.

(c)

Request for Consent.  If Tenant requests Landlord’s consent to a Transfer, then, at least thirty (30) days prior to the effective date of the proposed
Transfer, Tenant shall provide Landlord with a written description of all terms and conditions of the proposed Transfer, copies of the proposed pertinent documentation, and the following information about
the proposed transferee: name and address; reasonably satisfactory information about its business and business history; its proposed use of the Premises; banking, financial, and other credit information; and
general references sufficient to enable Landlord to determine the proposed transferee’s creditworthiness and character (collectively, the “ Transfer Notice”).  Concurrently with the Transfer Notice, Tenant
shall pay to Landlord a fee of $2,000 to defray Landlord’s expenses in reviewing such request, and Tenant shall reimburse Landlord within ten (10) days upon request for its reasonable attorneys’ fees incurred
in connection with considering any request for consent to a Transfer, not to exceed $2,500 per request.

Conditions to Consent.  If Landlord consents to a proposed Transfer, then the proposed transferee shall deliver to Landlord a written agreement
whereby it expressly assumes Tenant’s obligations hereunder.  No Transfer shall release Tenant from its obligations under this Lease, but rather Tenant and its transferee shall be jointly and severally liable
therefor.  Landlord’s consent to any Transfer shall not be deemed consent to any subsequent Transfers.  Tenant shall pay for the cost of any demising walls or other improvements necessitated by a proposed
subletting or assignment.

(d)

(e)

Attornment by Subtenants.  Each sublease by Tenant hereunder shall be subject and subordinate to this Lease and to the matters to which this
Lease is or shall be subordinate, and each subtenant by entering into a sublease is deemed to have agreed that in the event of termination, re-entry or dispossession by Landlord under this Lease, Landlord may,
at its option, either terminate the sublease or take over all of the right, title and interest of Tenant,  as  sublandlord,  under  such  sublease,  and  such  subtenant  shall,  at  Landlord’s  option,  attorn  to  Landlord
pursuant to the then executory provisions of such sublease, except that Landlord shall not be: (1) liable for any previous act or omission of Tenant under such sublease; (2) subject to any counterclaim, offset or
defense that such subtenant might have against Tenant; (3) bound by any previous modification of such sublease or by any rent or additional rent or advance rent which such subtenant might have paid for
more than the current month to Tenant, and all such rent shall remain due and owing, notwithstanding such advance payment; (4) bound by any security or advance rental deposit made by such subtenant
which is not delivered or paid over to Landlord and with respect to which such subtenant shall look solely to Tenant for refund or reimbursement; or (5) obligated to perform any work in

151177627 v8

12

 
 
the subleased space or to prepare it for occupancy, and in connection with such attornment, the subtenant shall execute and deliver to Landlord any instruments Landlord may reasonably request to evidence
and confirm such attornment.  Each subtenant or licensee of Tenant shall be deemed, automatically upon and as a condition of its occupying or using the Premises or any part thereof, to have agreed to be
bound by the terms and conditions set forth in this Section 10(e).  The provisions of this Section 10(e) shall be self-operative, and no further instrument shall be required to give effect to this provision.  If an
Event of Default occurs while the Premises or any part thereof are subject to a sublease, then Landlord, in addition to its other remedies, may collect directly from such subtenant all rents becoming due to
Tenant and apply such rents against Rent.  Tenant authorizes its subtenant to make payments of rent directly to Landlord upon receipt of notice from Landlord to do so following the occurrence of an Event of
Default hereunder.

part of the Premises (a “Permitted Transfer”) to the following types of entities (a “Permitted Transferee”) without the written consent of Landlord:

(f)

Permitted Transfers.  Notwithstanding to the contrary contained in this Lease, Tenant may Transfer all or part of its interest in this Lease or all or

(1)

an Affiliate of Tenant;

(2)
Tenant’s stocks on a nationally recognized stock exchange;

any persons  acquiring a controlling interest in Tenant in connection with a bona fide private equity placement financing or an initial public offering of

any corporation, limited partnership, limited liability partnership, limited liability company or other business entity in which or with which Tenant, or
(3)
its corporate successors or assigns, is merged or consolidated, in accordance with applicable statutory provisions governing merger and consolidation of business
entities, so long as (A) Tenant’s obligations hereunder are assumed by the entity surviving such merger or created by such consolidation; and (B) the Tangible
Net Worth of the surviving or created entity is not less than the Tangible Net Worth of Tenant as of the date of execution of this Lease; or

any corporation, limited partnership, limited liability partnership, limited liability company or other business entity acquiring all or substantially all of

(4)
Tenant’s assets if such entity’s Tangible Net Worth after such acquisition is not less than the Tangible Net Worth of Tenant as of the date of execution of this
Lease.

Tenant shall promptly notify Landlord of any such Permitted Transfer.  Tenant shall remain liable for the performance of all of the obligations of Tenant hereunder, or if Tenant no longer exists because of a
merger, consolidation, or acquisition, the surviving or acquiring entity shall expressly assume in writing the obligations of Tenant hereunder.  Additionally, the Permitted Transferee shall comply with all of
the terms and conditions of this Lease, including the Permitted Use.  No later than five (5) Business Days after the effective date of any Permitted Transfer, Tenant agrees to furnish Landlord with (A) copies of
the instrument effecting any of the foregoing Transfers, which copies of such instruments may be redacted by Tenant, (B) documentation establishing Tenant’s satisfaction of the requirements set forth above
applicable to any such Transfer, and (C) evidence of insurance as required under this Lease with respect to the Permitted Transferee, provided that Landlord executes a non-disclosure agreement provided by
Tenant.  The occurrence of a Permitted Transfer shall not waive Landlord’s rights as to any subsequent Transfers.  “ Tangible Net Worth” means the excess of total assets over total liabilities, in each case as
determined in accordance with generally accepted accounting principles consistently applied (“GAAP”).  Any subsequent Transfer by a Permitted Transferee shall be subject to the terms of this Section 10.

151177627 v8

13

 
 
(g)

Additional Compensation.  Tenant shall pay to Landlord, immediately upon receipt thereof, fifty percent (50%) of the excess of all compensation
received by Tenant for a Transfer over the Rent allocable to the portion of the Premises covered thereby, after deducting the following costs and expenses for such Transfer (which costs will be amortized over
the  term  of  the  sublease  or  assignment  pursuant  to  sound  accounting  principles  and  deducted  monthly  from  such  excess):    (1)  brokerage  commissions  and  reasonable  attorneys’  fees;  (2)  advertising  for
subtenants or assignees; (3) the actual costs paid in making any improvements or substitutions in the Premises required by any sublease or assignment; and (4) the costs of any inducements or concessions or
rental reductions or abatement given to the subtenant or assignee.

(h)

Landlord’s  Option.    Notwithstanding  anything  to  the  contrary  contained  in  this Article  10,  except  in  connection  with  Permitted  Transfers,
Landlord  shall  have  the  option,  by  giving  written  notice  to  Tenant  within  thirty  (30)  days  after  receipt  of  any  Transfer  Notice  with  respect  to  (i)  a  proposed  assignment  of  this  Lease  by  Tenant,  or  (ii)  a
proposed sublease of the entire Premises (the “Subject Space”) to (x) recapture the Subject Space, or (y) take an assignment or sublease of the Subject Space from Tenant.  Such recapture, or sublease or
assignment notice shall cancel and terminate this Lease, or create a sublease or assignment, as the case may be, with respect to the Subject Space as of the date stated in the Transfer Notice as the effective date
of the proposed Transfer until the last day of the term of the Transfer as set forth in the Transfer Notice.  If Landlord declines, or fails to elect in a timely manner to recapture, sublease or take an assignment of
the Subject Space under this Section 10(h), then, provided Landlord has consented to the proposed Transfer, Tenant shall be entitled to proceed to transfer the Subject Space to the proposed Transferee, subject
to provisions of this Section 10.  

11.

Insurance; Waivers; Subrogation; Indemnity.

(a)

Indemnity Agreement.  TO THE FULLEST EXTENT PERMITTED BY LAW AND SUBJECT TO LANDLORD’S INDEMNIFICATION
OBLIGATIONS BELOW AND FURTHER SUBJECT TO THE MUTUAL WAIVERS OF SUBROGATION SET FORTH IN  SECTION 11(d), TENANT WILL DEFEND, INDEMNIFY AND
HOLD  LANDLORD  HARMLESS  FROM  AND  AGAINST  ALL  CLAIMS  (AS  DEFINED  HEREIN)  ARISING  OUT  OF  OR  RELATING  (DIRECTLY  OR  INDIRECTLY)  TO  (I)  THE
CONDUCT OR MANAGEMENT OF THE PREMISES OR OF ANY BUSINESS THEREIN, OR ANY WORK OR THING WHATSOEVER DONE, OR ANY CONDITION CREATING IN OR
ABOUT THE PREMISES DURING THE TERM; (II) ANY ACT, OMISSION, BREACH OF ANY PROVISION OF THIS LEASE, OR NEGLIGENCE OF TENANT OR ANY OF TENANT’S
LICENSEES OR THE PARTNERS, DIRECTORS, OFFICERS, AGENTS, EMPLOYEES, INVITEES OR CONTRACTORS OF TENANT OR ANY OF TENANT’S LICENSEES; AND (III)
ANY ACCIDENT,  INJURY  OR  DAMAGE  WHATSOEVER  OCCURRING  IN  OR AT  THE  PREMISES.    TO  THE  FULLEST  EXTENT  PERMITTED  BY  LAW AND  SUBJECT  TO  THE
MUTUAL WAIVERS OF SUBROGATION SET FORTH IN  SECTION 11(d), LANDLORD AGREES TO INDEMNIFY TENANT AND TENANT PARTY FROM AND AGAINST ANY AND
ALL  CLAIMS  ARISING  FROM  INJURY  OR  DEATH  OF  ANY  PERSON  OR  DAMAGE  TO  OR  LOSS  OF  ANY  PHYSICAL  PROPERTY  OCCURRING  WITHIN  OR  ABOUT  THE
PREMISES, THE BUILDING, THE PROJECT AND/OR THE COMPLEX, TO THE EXTENT ARISING OUT OF LANDLORD’S OR INDEMNITEES’ GROSS NEGLIGENCE, WILLFUL
MISCONDUCT OR BREACH OF THIS LEASE.

Tenant’s Insurance.  Effective as of the Delivery Date and continuing throughout the Term, Tenant shall maintain insurance of the types and in the
amounts described below.  Insurance shall be obtained from insurance carriers rated not less than A-VIII by A.M. Best Company and licensed to business in the State.  Tenant insurance policy deductibles
shall be the responsibility of the Tenant and shall be less than $25,000 unless approved by Landlord.  Tenant’s insurance policies shall be primary and not

(b)

151177627 v8

14

 
 
require any contribution by any insurance maintained by Landlord, and Tenant shall require the insurer with respect to each policy required in this Section 11(b) to waive subrogation rights against Landlord
and the other Landlord Parties.  If Tenant fails to comply with the foregoing insurance requirements or to deliver to Landlord the certificates or evidence of coverage required herein, Landlord, in addition to
any other remedy available pursuant to this Lease or otherwise, may, but shall not be obligated to, obtain such insurance and Tenant shall pay to Landlord the cost thereof, plus an a dministrative fee of three
percent (3%) of the cost thereof.  It is expressly understood and agreed that the foregoing minimum limits of insurance coverage shall not limit the liability of Tenant for its acts or omissions as provided in this
Lease.  Tenant may satisfy requirements of this Section 11(b) with policies that cover both the Premises and other properties, on condition that any general aggregate limits under these “blanket” policies apply
separately to the Premises, the requirements in this Section 11(b) are otherwise satisfied, and these policies do not otherwise impair the rights of Landlord or violate requirements of this Lease. Certificates for
all insurance carried pursuant to this Section 11(b) shall be delivered to Landlord before the Delivery Date and thereafter upon request and (even if not requested) upon the renewal or replacement of any
required  policy.  Tenant  shall  ensure  that  Landlord  is  notified  no  less  than  ten  (10)  days  before  cancellation  of  any  required  policy,  and  shall  cause  its   certificates  of  insurance  to  indicate  this.  Failure  of
Landlord to demand such certificate or other evidence of full compliance with these insurance requirements or failure of Landlord to identify a deficiency from evidence that is provided shall not be construed
as  a  waiver  of  Tenant’s  obligation  to  maintain  such  insurance.     These  requirements  and  limits  are  subject  to  review  and  modification  by  Landlord  in  its  commercially  reasonable  determination  (i)  in
recognition of changes in the occupancy, exposure, or insurance marketplace, and/or (ii) as a result of Tenant’s use of Hazardous Materials or other items in the Premises as set forth in the list of Hazardous
Materials  in  the  Environmental  Questionnaire  attached  hereto  as Exhibit J  to  be  provided  by  Tenant  to  Landlord  no  later  than  the  Commencement  Date.    The  term  “Landlord Parties”  means  Landlord;
Landlord’s  property  manager  with  respect  to  the  Premises;  Landlord’s  Mortgagee;  other  entities  or  individuals  Landlord  may  designate  from  time  to  time  to  be  in cluded  as  additional  insureds  (e.g.,  by
requiring that they be listed as additional insureds on certificates of insurance); the successors and assigns, and direct and indirect affiliates, of each of the foregoing; and, with respect to each of the foregoing,
its shareholders, trustees, beneficiaries, managers, officers, directors, employees, and agents.

liability assumed under an insured contract naming the Landlord and the other Landlord Parties as additional insureds on a primary and non-contributory basis with limits of not less than $1,000,000 each
occurrence and $2,000,000 aggregate per location shall be maintained.  Evidence of commercial general liability insurance granting no less than thirty (30) days’ notice of cancellation for reasons other than
non-payment shall be provided by the ISO form (CG 20 11, CG 20 26 11 85, or a substitute providing equivalent coverage and under the commercial umbrella policy) prior to Lease inception and no less than
fifteen (15) days prior to each insurance policy renewal during the term of the Lease.

broad as the ISO business auto coverage form (CA 00 01) to cover owned, non-owned, hired, and borrowed autos with not less than $1,000,000 combined single limit shall be obtained.  If the Tenant does not
own any vehicles, non-owned and hired auto liability insurance with a not less than $1,000,000 limit shall be maintained.  Tenant shall require similar coverage for any contract vehicles that it engages for
transportation of personnel or personal property to or from the Premises.

Subordination; Attornment; Notice to Landlord’s Mortgagee.

(a)

Subordination.  This Lease shall be subordinate to any deed of trust, mortgage, or other security instrument (each, a “Mortgage”), or any ground
lease, master lease, or primary lease (each, a “Primary Lease”), that now or hereafter covers all or any part of the Premises (the mortgagee under any such Mortgage, beneficiary under any such deed of trust,
or the lessor under any such Primary Lease is referred to herein as a “Landlord’s Mortgagee”).  The automatic subordination to Landlord’s Mortgagee provided for in this Section 12 is expressly conditioned
upon  such  Landlord’s  Mortgagee,  agreeing  that  as  long  as  no  Event  of  Default  occurs  under  this  Lease,  such  Landlord’s  Mortgagee  will  not  disturb  Tenant’s  rights  of  possession  under  this  Lease.   Any
Landlord’s Mortgagee may elect at any time, unilaterally, to make this Lease superior to its Mortgage, Primary Lease, or other interest in the Premises by so notifying Tenant in writing.  The provisions of this
Section  shall  be  self-operative  and  no  further  instrument  of  subordination  shall  be  required;  however,  in  confirmation  of  such  subordination,  Tenant  shall,  subject  to  Tenant’s  receipt  of  a  commercially
reasonable non-disturbance agreement,  execute and return to Landlord (or such other party designated in writing by Landlord) within ten (10) Business Days after written request therefor such documentation,
in  recordable  form  if  required,  as  a  Landlord’s  Mortgagee  may  reasonably  request  to  evidence  the  subordination  of  this  Lease  to  such  Landlord’s  Mortgagee’s  Mortgage  or  Primary  Lease  (including  a
subordination,  non-disturbance  and  attornment  agreement)  or,  if  the  Landlord’s  Mortgagee  so  elects,  the  subordination  of  such  Landlord’s  Mortgagee’s  Mortgage  or  Primary  Lease  to  this
Lease.  Notwithstanding the foregoing, Tenant shall not be obligated to execute any document which alters any material provision of the Lease.

Attornment.  Tenant shall attorn to any party succeeding to Landlord’s interest in the Premises, whether by purchase, foreclosure, deed in lieu of
foreclosure, power of sale, termination of lease, or otherwise, upon such party’s request, and shall execute such commercially reasonable agreements confirming such attornment as such party may reasonably
request.  Notwithstanding the foregoing, Tenant shall not be obligated to execute any document which alters any material provision of the Lease.

(b)

Notice to Landlord’s Mortgagee.  Tenant shall not seek to enforce any remedy it may have for any default on the part of Landlord without first
giving written notice by certified mail, return receipt requested, specifying the default in reasonable detail, to any Landlord’s Mortgagee whose address has been given to Tenant, and affording such Landlord’s
Mortgagee a reasonable opportunity to perform Landlord’s obligations hereunder.

(c)

13.

Rules  and  Regulations.   Tenant  shall  comply  with  the  rules  and  regulations  of  the  Building  (the  “Rules  and  Regulations”)  which  are  attached  hereto  as
Exhibit E.  Landlord may, from time to time, change such rules and regulations for the safety, care, or cleanliness of the Building and related facilities, provided that such changes are applicable to all tenants

Tenant  in  writing  and  are  enforced  by  Landlord  in  a  non-discriminatory  manner.    Tenant  shall  be  responsible  for  the  compliance  with  such  rules  and  regulations  by  each  Ten ant Party.    The  Rules  and
Regulations shall not be construed in any way to modify or amend, in whole or part, the terms, covenants, agreements and conditions of this Lease, and in the event of any conflict between the terms of Rules
and Regulations and this Lease, terms of this Lease shall control.

terminate as of the date of the Taking.

(a)

Total Taking.  If the entire Building or Premises are taken by right of eminent domain or conveyed in lieu thereof (a “Taking”), this Lease shall

(b)

Partial Taking - Tenant’s Rights.  If any part of the Building becomes subject to a Taking and such Taking will prevent Tenant from conducting
its business in the Premises in a manner reasonably comparable to that conducted immediately before such Taking for a period of more than one hundred twenty (120) days, then Tenant may terminate this
Lease as of the date of such Taking by giving written notice to Landlord within thirty (30) days after the Taking, and Rent shall be apportioned as of the date of such Taking.  If Tenant does not terminate this
Lease,  then  Rent  shall  be  abated  on  a  reasonable  basis  as  to  that  portion  of  the  Premises  rendered  untenantable  by  the  Taking.   TENANT  HEREBY  WAIVES ANY AND ALL  RIGHTS  IT  MIGHT
OTHERWISE HAVE PURSUANT TO SECTION 1265.130 OF THE CALIFORNIA CODE OF CIVIL PROCEDURE.

Partial  Taking  -  Landlord’s  Rights.    If  any  material  portion,  but  less  than  all,  of  the  Building  becomes  subject  to  a  Taking,  or  if  Landlord  is
required to pay any of the proceeds arising from a Taking to a Landlord’s Mortgagee, then Landlord may terminate this Lease by delivering written notice thereof to Tenant within fifteen (15) days after such
Taking, and Rent shall be apportioned as of the date of such Taking.  If Landlord does not so terminate this Lease, then this Lease will continue, but if any portion of the Premises has been taken, Rent shall
abate as provided in the next to last sentence of Section 14(b).

(c)

Award.    If  any  Taking  occurs,  then  Landlord  shall  receive  the  entire  award  or  other  compensation  for  the  Land,  the  Building,  and  other
improvements taken; however, Tenant may separately pursue a claim (to the extent it will not reduce Landlord’s award) against the condemnor for the value of Tenant’s personal property which Tenant is
entitled to remove under this Lease, moving costs, loss of business, and other claims it may have (excluding any claim related to its leasehold interest).

(d)

(e)

Repair.  If the Lease is not terminated, Landlord shall promptly proceed with reasonable diligence to restore the remaining part of the Premises and
Building substantially to their former condition to the extent feasible to constitute a complete and tenantable Building and Premises; provided, however, that Landlord shall only be required to reconstruct
building standard leasehold improvements existing in the Premises as of the date of the Taking, and Tenant shall be required to pay the cost for restoring any other leasehold improvements, and the Rent shall
be decreased proportionately to reflect the loss of any portion of the Premises rendered untenantable during the restoration thereof.  In no event shall Landlord be required to spend more than the condemnation
proceeds received by Landlord for such repair.

Fire or Other Casualty.

deliver to Tenant within sixty (60) days after such Casualty a good faith estimate (the “Damage Notice”) of the time needed to repair the damage caused by such Casualty.

(a)

Repair Estimate.  If the Premises or the Building are damaged by fire or other casualty (a “Casualty”),  Landlord  shall  use  good  faith  efforts  to

(b)

Tenant’s Rights.  If a material portion of the Premises is damaged by Casualty such that Tenant is prevented from conducting its business in the
Premises in a manner reasonably comparable to that conducted immediately before such Casualty,  and Landlord estimates that the damage caused thereby cannot be repaired within two hundred seventy (270)
days after the date of the Casualty (the “Repair Period”), then Tenant may terminate this Lease by delivering written notice to Landlord of its election to terminate within thirty (30) days after the Damage
Notice has been delivered to Tenant.  Tenant shall also have the right to terminate if Casualty occurs during the last one (1) year of the Term and the Casualty substantially impairs, in Tenant’s rea sonable
judgment, Tenant’s operation of its business in the Premises for more than sixty (60) days.

(c)

Landlord’s Rights.  If a Casualty damages the Premises or a material portion of the Building and: (1) Landlord estimates that the damage to the
Premises cannot  be  repaired  within  the  Repair  Period;  (2)  the  damage  to  the  Premises  exceeds  fifty  percent  (50%)  of  the  replacement  cost  thereof  (excluding  foundations  and  footings),  as  estimated  by
Landlord,  and  such  damage  occurs  during  the  last  eighteen  (18)  months  of  the  Term  (unless  Tenant  exercises  any  renewal  rights  it  may  have  in  the  Lease);  (3)  regardless  of  the  extent  of  damage  to  the
Premises, Landlord makes a good faith determination that restoring the Building would be uneconomical; or (4) Landlord is required to pay any insurance proceeds arising out of the Casualty to a Landlord’s
Mortgagee, then Landlord may terminate this Lease by giving written notice of its election to terminate within thirty (30) days after the Damage Notice has been delivered to Tenant.

(d)

Repair Obligation.  If neither party elects to terminate this Lease following a Casualty, then Landlord shall, within a reasonable time after such
Casualty, begin to repair the Premises and shall proceed with reasonable diligence to restore the Premis es to substantially the same condition as they existed immediately before such Casualty; however, other
than building standard leasehold improvements Landlord shall not be required to repair or replace any Tenant Improvements or Alterations or betterments within the Premises (which shall be promptly and
with due diligence repaired and restored by Tenant at Tenant’s sole cost and expense) or any furniture, equipment, trade fixtures or personal property of Tenant or others in the Premises or the Building, and
Landlord’s obligation to repair or restore the Premises shall be limited to the extent of the insurance proceeds actually received by Landlord for the Casualty in question.  If Landlord fails to complete repairs
to the Premises within two hundred seventy (270) days after the date of the Casualty, subject to delays caused by Force Majeure Events, then Tenant shall have the right to terminate the Lease upon written
notice delivered to Landlord at any time after such two hundred seventy (270) day period and prior to Landlord’s substantial completion of such repairs.

abated on a reasonable basis from the date of damage until the completion of Landlord’s repairs (or until the date of termination of this Lease by Landlord or Tenant as provided above, as the case may be).

(e)

Abatement of Rent.  If the Premises are damaged by Casualty, Rent for the portion of the Premises rendered untenantable by the damage shall be

(f)

Waiver of Statutory Provisions.  The provisions of this Lease, including this Section 15, constitute an express agreement between Landlord and
Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises, the Building or any other portion of the Project, and any statute or regulation of the State of California, including,
without limitation, Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the absence of an express agreement between the
parties, and any other statute or regulation, now or hereafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises, the Building or any other portion of
the Project.  

16.

Personal Property Taxes.  Tenant shall be liable for all taxes levied or assessed against personal property, furniture, or fixtures placed by Tenant in the Premises or in or on
the Building or Project.  If any taxes for which Tenant is liable are levied or assessed against Landlord or Landlord’s property and Landlord elects to pay the same, or if the assessed value of Landlord’s
property  is  increased  by  inclusion  of  such  personal  property,  furniture  or  fixtures  and  Landlord  elects  to  pay  the  taxes  based  on  such  increase,  then  Tenant  shall  pay  to  Landlord,  within  thirty  (30)  days
following written request therefor, the part of such taxes for which Tenant is primarily liable hereunder.

or the Project for any work performed, materials furnished, or obligation incurred by or at the request of Tenant, within the time and in the manner required by Section 8(c);

continuance  of  such  failure  for  a  period  of  thirty  (30)  calendar  days  or  more  after  Landlord  has  delivered  to  Tenant  written  notice  thereof;  provided,  however,  if  such  default  is  of  the  type  which  cannot
reasonably be cured within thirty (30) days, then Tenant shall have such longer time as is reasonably necessary provided Tenant commences to cure within ten (10) days after receipt of written notice from
Landlord and diligently prosecutes such cure to completion; and

(f)

Insolvency.  The filing of a petition by or against Tenant (the term “Tenant” shall include, for the purpose of this Section 17(g), any guarantor of
Tenant’s obligations hereunder): (1) in any bankruptcy or other insolvency proceeding; (2) seeking any relief under any state or federal debtor relief law; (3) for the appointment of a liquidator or receiver for
all or substantially all of Tenant’s property or for Tenant’s interest in this Lease; or (4) for the reorganization or modification of Tenant’s capital structure; however, if such a petition is filed against Tenant,
then such filing shall not be an Event of Default unless Tenant fails to have the proceedings initiated by such petition dismissed within one hundred twenty (120) calendar days after the filing thereof.

(g)

18.

Remedies.  Upon an Event of Default, Landlord shall have, in addition to any other remedies available to Landlord at law or in equity, the option to pursue any one or more

of the following remedies, each and all of which shall be cumulative and nonexclusive, without any notice or demand whatsoever.

Terminate  this  Lease,  in  which  event  Tenant  shall  immediately  surrender  the  Premises  to  Landlord,  and  if  Tenant  fails  to  do  so,  Landlord  may,
without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be
occupying the Premises or any part thereof, without being liable for prosecution or any claim for damages therefor; and Landlord may recover from Tenant the following:

(a)

until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

(i)

(ii)

The worth at the time of award of any unpaid rent which has been earned at the time of such termination; plus

The worth at the time of award of the amount by which the unpaid rent which would have been earned after termination

award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

(iii)

The worth at the time of award of the amount by which the unpaid rent for the balance of the Lease Term after the time of

(iv)

Any  other  amount  necessary  to  compensate  Landlord  for  all  the  detriment  proximately  caused  by  Tenant’s  failure  to

perform its obligations under this Lease or which in the ordinary

151177627 v8

20

 
 
course of things would be likely to result therefrom, specifically including, but not limited to, brokerage commissions and advertising expenses incurred, expenses of remodeling the Premises or any portion
thereof for a new tenant, whether for the same or a different use, and any special concessions made to obtain a new tenant; and

(v)

At Landlord’s election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time

by applicable law.

The term “rent” as used in this Section 18 shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or
to others.  As used in Sections 18(a)(i) and (ii) above, the “worth at the time of award” shall be computed by allowing interest at the Default Rate, but in no case greater than the maximum amount of such
interest  permitted  by  law.   As  used  in  Section 18(a)(iii)  above,  the  “worth  at  the  time  of  award”  shall  be  computed  by  discounting  such  amount  at  the  discount  rate  of  the  Federal  Reserve  Bank  of  San
Francisco at the time of award plus one percent (1%).

Landlord shall have the remedy described in California Civil Code Section 1951.4 (lessor may continue lease in effect after lessee’s breach and
abandonment and recover Rent as it becomes due, if lessee has the right to sublet or assign, subject only to reasonable limitations).  Accordingly, if Landlord does not elect to terminate this Lease on account
of any Event of Default by Tenant, Landlord may, from time to time, without terminating this Lease, enforce all of its rights and remedies under this Lease, including the right to recover all rent as it becomes
due.

(b)

Subleases of Tenant.  Whether or not Landlord elects to terminate this Lease on account of any Event of Default by Tenant, as set forth in this
Section 18, Landlord shall have the right to terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises or may, in
Landlord’s sole discretion, succeed to Tenant’s interest in such subleases, licenses, concessions or arrangements.  In the event of Landlord’s election to succeed to Tenant’s interest in any such subleases,
licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder.

(c)

Form of Payment After Default.  Following the occurrence of an Event of Default by Tenant, Landlord shall have the right to require that any or
all subsequent amounts paid by Tenant to Landlord hereunder, whether in the cure of the default in question or otherwise, be paid in the form of cash, money order, cashier’s or certified check drawn on an
institution reasonably acceptable to Landlord, or by other means approved by Landlord, notwithstanding any prior practice of accepting payments in any different form.

(d)

Efforts  to  Relet.    For  the  purposes  of  this Section 18,  Tenant’s  right  to  possession  shall  not  be  deemed  to  have  been  terminated  by  efforts  of
Landlord to relet the Premises, by its acts of maintenance or preservation with respect to the Premises, or by appointment of a receiver to protect Landlord’s interests hereunder.  The foregoing enumeration is
not exhaustive, but merely illustrative of acts which may be performed by Landlord without terminating Tenant’s right to possession.

(e)

Landlord Defaults and Tenant Remedies.  Except as otherwise provided in this Lease and specifically subject to Section 26(b), if Landlord fails in
the performance of any of Landlord’s obligations under this Lease and such failure continues for thirty (30) days after Landlord’s receipt of written notice thereof from Tenant (and an additional reasonable
time after such receipt if (A) such failure cannot be cured within such thirty (30) day period, and (B) Landlord commences curing such failure within such thirty (30) day period and thereafter diligently
pursues the curing of such failure), then Tenant shall be entitled to exercise any remedies that Tenant may have at law or in equity.  TENANT WAIVES ANY

19.

Payment by Tenant; Non-Waiver; Cumulative Remedies.

(a)

Payment by Tenant.  Upon any Event of Default, Tenant shall pay to Landlord all reasonable costs incurred by Landlord (including court costs and
reasonable attorneys’ fees and expenses) in: (1) obtaining possession of the Premises; (2) removing and storing Tenant’s or any other occupant’s property; (3) repairing, restoring, altering, remodeling, or
otherwise putting the Premises into condition reasonably acceptable to a new tenant (provided that Tenant shall not be responsible for costs to change the character of the Premises from an office use to a
primarily  retail,  industrial  or  other  non-office  type  of  use);  (4)  if  Tenant  is  dispossessed  of  the  Premises  and  this  Lease  is  not  terminated,  reletting  all  or  any  part  of  the  Premises  (including  brokerage
commissions, cost of tenant finish work, and other costs incidental to such reletting); (5) performing Tenant’s obligations which Tenant failed to perform; and (6) enforcing, or advising Landlord of, its rights,
remedies, and recourses arising out of the Event of Default.  To the full extent permitted by Law, Landlord and Tenant agree the federal and state courts of the state in which the Premises are located shall have
exclusive jurisdiction over any matter relating to or arising from this Lease and the parties’ rights and obligations under this Lease.

No Waiver.  Landlord’s acceptance of Rent following an Event of Default shall not waive Landlord’s rights regarding such Event of Default.  No
waiver by Landlord of any violation or breach of any of the terms contained herein shall waive Landlord’s rights regarding any future violation of such term.  Landlord’s acceptance of any partial payment of
Rent shall not waive Landlord’s rights with regard to the remaining portion of the Rent that is due, regardless of any endorsement or other statement on any instrument delivered in payment of Rent or any
writing delivered in connection therewith; accordingly, Landlord’s acceptance of a partial payment of Rent shall not constitute an accord and satisfaction of the full amount of the Rent that is due.

(b)

Cumulative Remedies.  Any and all remedies set forth in this Lease:  (1) shall be in addition to any and all other remedies Landlord may have at
law or in equity; (2) shall be cumulative; and (3) may be pursued successively or concurrently as Landlord may elect.  The exercise of any remedy by Landlord shall not be deemed an election of remedies or
preclude Landlord from exercising any other remedies in the future.

(c)

20.

21.

Intentionally Omitted.

Surrender of Premises.

(a)

General.  No act by Landlord shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept a surrender of the Premises
shall be valid unless it is in writing and signed by Landlord.  At the expiration or termination of this Lease, Tenant s hall deliver to Landlord the Premises with all improvements located therein in good repair
and condition, free of Hazardous Materials for which Tenant has responsibility under this Lease, in broom-clean condition including cleaning of interior surface of all walls, flooring, ceiling and/ or roof deck
due  to  Tenant’s  specific  use  (with  such  cleaning  by  commercial  cleaning  application  as  reasonably approved  by  Landlord),  reasonable  wear  and  tear and  condemnation  and  Casualty  damage (as  to  which
Section 14  and Section 15  shall  control)  excepted,  and  shall  deliver  to  Landlord  all  keys  to  the  Premises.  Tenant  shall  remove  all  unattached  trade  fixtures,  furniture,  and  personal  property  placed  in  the
Premises or elsewhere in the Building by Tenant (but Tenant may not remove any such item which was paid for, in whole or in part, by Landlord or any wiring or cabling unless Landlord requires such
removal).  Additionally, at Landlord’s option, Tenant shall (not later than ten (10) days after the expiration or earlier t ermination of the Lease) remove such alterations, additions (including stairs and bank
vaults),  improvements,  trade  fixtures,  personal  property,  equipment,  wiring,  conduits,  cabling  and  furniture  (including  Tenant’s  Off-Premises  Equipment)  installed  by  Ten ant as  Landlord  may  request;
however, Tenant shall not be required to remove either the Tenant Improvements or

151177627 v8

22

 
 
any Alterations to the Premises or the Project unless a Removal Notice was provided to Tenant at the time of Landlord’s consent to installation. Tenant shall repair all damage caused by such removal.  All
items  not  so  removed  shall,  at  Landlord’s  option,  be  deemed  to  have  been  abandoned  by  Tenant  and  may  be  appropriated,  sold,  stored,  destroyed,  or  otherwise  disposed  of  by  Landlord  at  Tenant’s  cos t
without notice to Tenant and without any obligation to account for such items; any such disposition shall not be considered a strict foreclosure or other exercise of Landlord’s rights in respect of the security
interest granted under Section 20.  The provisions of this Section 21 shall survive the expiration or earlier termination of the Lease.

(b)

Environmental Assessment.  Prior to the expiration of the Lease (or within thirty (30) days after any earlier termination) plus additional time (but in
no event in excess of thirty (30) days) as may be required by Tenant to obtain governmental sign-offs in connection with the decommissioning, Tenant shall clean and otherwise decommission all interior
surfaces (including floors, walls, ceilings, and counters), piping, supply lines, waste lines and plumbing in or serving the Premises, and all exhaust or other ductwork in or serving the Premises, in each case
that has carried, released or otherwise been exposed to any Hazardous Materials due to Tenant’s use or occupancy of the Premises, and shall otherwise clean the Premises so as to permit the Environmental
Assessment called for by this Section 21(b) to be issued. For the avoidance of doubt, Tenant shall not be liable for any Hazardous Materials (i) which were placed on the Premises or the Project by Landlord or
its employees, agents or contractors or any third parties not under Tenant’s control, (ii) which were located at the Premises or the Project on the Delivery Date, or (iii) which migrated through air, water or soil
from a location outside of the Premises through no act, omission or fault of Tenant or Tenant Party.  Prior to the expiration of this Lease (or within thirty (30) days after any earlier termination), Tenant, at
Tenant’s expense, shall obtain for Landlord a report (an “ Environmental Assessment”) addressed to Landlord (and, at Tenant’s election, Tenant) by a reputable licensed environmental engineer or industrial
hygienist that is designated by Tenant and acceptable to Landlord in Landlord’s reasonable discretion, which report shall be based on the environmental engineer’s inspection of the Premises and shall state, to
Landlord’s reasonable satisfaction, that:  (a) the Hazardous Materials described in the first sentence of this paragraph, to the extent, if any, existing prior to such decommissioning, have been removed in
accordance with applicable Laws; (b) all Hazardous Materials described in the first sentence of this paragraph, if any, have been removed in accordance with Applicable Laws from the interior  surfaces of the
Premises (including floors, walls, ceilings, and counters), piping, supply lines, waste lines and plumbing, and all such exhaust or other ductwork in the Premises, may be reused by a subsequent tenant or
disposed of in compliance with applicable Laws without incurring special costs or undertaking special procedures for demolition, disposal, investigation, assessment, cleaning or removal of such Hazardous
Materials and without giving notice in connection with such Hazardous Materials; and (c) the Premises may be reoccupied for office, research and development, or laboratory use, demolished or renovated
without  incurring  special  costs  or  undertaking  special  procedures  for  disposal,  investigation,  assessment,  cleaning  or  removal  of  Hazardous  Materials  described  in  the  first  sentence  of  this  paragraph  and
without giving notice in connection with Hazardous Materials.  Further, for purposes of clauses (b) and (c), “special costs” or “special procedures” shall mean costs or procedures, as the case may be, that
would  not  be  incurred  but  for  the  nature  of  the  Hazardous  Materials  as  Hazardous  Materials  instead  of  non-hazardous  materials.    The  report  shall  also  include  reasonable  detail  concerning  the  clean-up
measures  taken,  the  clean-up  locations,  the  tests  run  and  the  analytic  results.    Tenant  shall  submit  to  Landlord  the  identity  of  the  applicable  consultants  and  the  scope  of  the  proposed  Environmental
Assessment  for  Landlord’s  reasonable  review  and  approval  at  least  thirty  (30)  days  prior  to  commencing  the  work  described  therein  or  at  least  sixty  (60)  days  prior  to  the  expiration  of  the  Lease  Term,
whichever is earlier.

Business Days’ prior written notice to Tenant perform such obligations at Tenant’s expense if Tenant has not commenced to do so within said five (5) Business Day period, and Tenant shall within ten (10)
days of written demand reimburse Landlord for all

(c)

Remedies.    If  Tenant  fails  to  perform  its  obligations  under Section 21(b),  without  limiting  any  other  right  or  remedy,  Landlord  may,  o n  five  (5)

151177627 v8

23

 
 
reasonable out-of-pocket costs and expenses incurred by Landlord in connection with such work.  Tenant’s obligations under Section 21(b) shall survive the expiration or earlier termination of this Lease.  In
addition, at Landlord’s election, Landlord may inspect the Premises and/or the Project for Hazardous Materials at Landlord’s cost and expense within sixty (60) days of Tenant’s surrender of the Premises at
the expiration or earlier termination of this Lease.  Tenant shall pay for all such  reasonable costs and expenses incurred by Landlord in connection with such inspection if such inspection reveals that a release
or threat of release of Hazardous Materials exists at the Project or Premises as a result of the violation of Section 25 by Tenant or a Tenant Party.

22.

Holding Over.  If Tenant fails to vacate the Premises at the end of the Term, then Tenant shall be a tenant at sufferance and, in addition to all other damages and remedies
to which Landlord may be entitled for such holding over, Tenant shall pay, in addition to the other Rent, Base Rent equal to one hundred fifty percent (150%) of the Base Rent payable during the last month of
the Term (as applicable, the “Holdover Rate”), and Tenant shall otherwise continue to be subject to all of Tenant’s obligations under this Lease.  The provisions of this  Section 22 shall not be deemed to limit
or  constitute  a  waiver  of  any  other  rights  or  remedies  of  Landlord  provided  herein  or  at  Law.    IF  TENANT  FAILS  TO  SURRENDER  THE  PREMISES  UPON  THE  TERMINATION  OR
EXPIRATION  OF  THIS  LEASE  (EXCEPT  AS  SET  FORTH  IN  THE  FOLLOWING  SENTENCE),  IN  ADDITION  TO  ANY  OTHER  LIABILITIES  TO  LANDLORD  ACCRUING
THEREFROM,  TENANT  SHALL  PROTECT,  DEFEND,  INDEMNIFY AND  HOLD  LANDLORD  HARMLESS  FROM ALL  LOSS,  COSTS  (INCLUDING  REASONABLE ATTORNEYS’
FEES)  AND  LIABILITY  RESULTING  FROM  SUCH  FAILURE,  INCLUDING  ANY  CLAIMS  MADE  BY  ANY  SUCCEEDING  TENANT  FOUNDED  UPON  SUCH  FAILURE  TO
SURRENDER, AND ANY LOST PROFITS TO LANDLORD RESULTING THEREFROM .  Notwithstanding the foregoing, if Tenant remains in the Premises at the end of the Term with the written
consent of Landlord, then Tenant shall be a month-to-month tenant at the Holdover Rate, and Tenant shall otherwise continue to be subject to all of Tenant’s obligations under this Lease.

23.

Certain Rights Reserved by Landlord.  Provided that the exercise of such rights does not unreasonably interfere with Tenant’s access to and occupancy of the Premises,

Landlord shall have the following rights:

(a)

Building Operations.  To make such inspections, repairs, alterations, additions, changes, or improvements, whether structural or otherwise, as are
expressly provided in this Lease, in and about the Project or Complex, as applicable, or any part thereof; to enter upon the Premises (after giving Tenant prior notice thereof, which may be oral notice, except in
cases of real or apparent emergency, in which case no notice shall be required) and, during the continuance of any such work, to temporarily close public space; to interrupt or temporarily suspend Building
services and facilities; and to change the arrangement and location of entrances or passageways, doors, and doorways, corridors, elevators, stairs, restrooms, or other public parts of the Building (after giving
Tenant three (3) business days’ notice thereof, except in cases or real or apparent emergency, in which case no notice shall be required);

Security.  To take such reasonable security measures as Landlord deems reasonably advisable (provided, however, that any such security measures
are for Landlord’s own protection, and Tenant acknowledges that Landlord is not a guarantor of the security or safety of any Tenant Party and that such security matters are the responsibility of Tenant);
including evacuating the Building for cause, suspected cause, or for drill purposes; temporarily denying access to the Building;

(b)

(c)

Prospective  Purchasers  and  Lenders.    To  enter  the  Premises  at  all  reasonable  hours  to  show  the  Premises  to  prospective  purchasers  or  lenders

upon prior notice (which may be oral notice); and

(d)

Prospective Tenants.  At any time during the last nine (9) months of the Term (or earlier if Tenant has notified Landlord in writing that it does not

desire to renew the Term) or at any time

151177627 v8

24

 
 
following the occurrence of an Event of Default, to enter the Premises at all reasonable hours upon reasonable advance notice to show the Premises to prospective tenants.

24.

Cell  Tower  Equipment.    Tenant  hereby  acknowledges  that  as  of  the  date  hereof,  there  are  two  cell  tower  equipment  located  on  the  roof  of  the  Building  and  related
equipment located in the electrical room in the underground parking garage (collectively, “Cell Tower Equipment”), which Cell Tower Equipment are owned by Pacific Bell Mobile Services and Spring
Spectrum Realty Company L.P. (“Cell Tower Owners”).  Landlord hereby represents to Tenant that the location and size of each Cell Tower Equipment on the rooftop and related equipment in the electric
room in the underground parking garage on Exhibit K attached to this Lease are accurate depiction of the current location and current size of the Cell Tower Equipment, and that the location or the size of the
Cell Tower Equipment shall not be modified during the Term, except as otherwise provided in the following:  (i) Communications Site Lease Agreement dated as of September 18, 1995, as amended, for
Pacific Bell Mobile Services, and (ii) PCS Site Agreement dated as of May 20, 1996, as amended, for Spring Spectrum Realty Group (such items set forth in (i) and (ii) to be collectively referred to as the
“Cell Tower Leases”).  Tenant shall not have any rights to access, use or have any other right to such Cell Tower Equipment.  Tenant shall provide Landlord and the Cell Tower Owners with access to the
Cell Tower Equipment (which shall be through the stairway inside the Building) upon reasonable advance notice (which may be oral notice), provided that (i) Landlord and/or the Cell Tower Owners shall not

installing, maintaining and removing the Telecommunications Equipment shall be borne solely by Tenant.  Upon the expiration of the Term or upon

disclosed by Tenant to anyone, by any manner or means, directly or indirectly (except to Tenant’s attorneys and accountants which have been informed of the confidentiality provisions of this Lease and
further except as Tenant shall be required under applicable laws including requirements of the Securities and Exchange Commission) without Landlord’s prior written consent.  The consent by Landlord to any
disclosures shall not be deemed to be a waiver on the part of Landlord of any prohibition against any future disclosure.

1.

Additional Rent.  Tenant shall pay to Landlord all costs (100%) of Common Area Maintenance Costs, Taxes, and Insurance for the Building, and Tenant’s Proportionate
Share of the annual Common Area Maintenance Costs (defined below) in the Complex (“Additional Rent”).  The estimated projected monthly Additional Rent for 2017 is $0.85 per rentable square feet, it

such estimate.  Landlord may make a good faith estimate of the Additional Rent to be due by Tenant for any calendar year or part thereof during the Term and provide such estimate to Tenant.  During each
calendar year or partial calendar year of the Term, Tenant shall pay to Landlord, in advance concurrently with each monthly installment of Base Rent, an amount equal to the estimated Additional Rent for
such calendar year or part thereof divided by the number of months therein.  From time to time, Landlord may estimate and re-estimate the Additional Rent to be due by Tenant and deliver a copy of the
estimate or re-estimate to Tenant.  Thereafter, the monthly installments of Additional Rent payable by Tenant shall be appropriately adjusted in accordance with the estimations so that, by the end of the
calendar year in question, Tenant shall have paid all of the Additional Rent as estimated by Landlord.  Any amounts paid based on such an estimate shall be subject to adjustment as herein provided when
actual Common Area Maintenance Costs are available for each calendar year.

Taxes.    Tenant  shall  pay  all  Taxes  for  the  Building,  and  Tenant’s  Proportionate  Share  of  Taxes  for  the  Complex  for  each  year  and  partial  year  falling  within  the
Term.    Tenant  shall  pay  Tenant’s  Proportionate  Share  of  Tax es  in  the  same  manner  as  provided  above  for  Tenant’s  Proportionate  Share  of  Common Area  Maintenance  Costs.    “Taxes”  shall  mean  taxes,
assessments,  and  governmental  charges  or  fees  whether  federal,  state,  county  or  municipal,  and  whether  they  be  by  taxing  districts  or  authorities  presently  taxing  or  by  others,  subsequently  created  or
otherwise, and any other taxes and assessments (including non-governmental assessments for common charges under a restrictive covenant or other private agreement that are not treated as part of Common
Area Maintenance Costs) now or hereafter attributable to the Project or Complex, as applicable (or its operation), excluding, however, penalties and interest thereon and federal and state taxes on income (if the
present method of taxation changes so that in lieu of or in addition to the whole or any part of any Taxes, there is levied on Landlord a capital tax directly on the rents received therefrom or a franchise tax,
assessment, or charge based, in whole or in part, upon such rents for the Project or Complex, as applicable, then all such taxes, assessments, or charges, or the part thereof so based, shall be deemed to be
included within the term “Taxes” for purposes hereof).  Taxes shall include the costs of consultants retained in an effort to lower taxes and all costs incurred in disputing any taxes or in seeking to lower the tax
valuation of the Project.  Taxes shall also include any assessment, tax, fee, levy or charge in addition to, or in substitution, partially or totally, of a ny assessment, tax, fee, levy or charge previously included
within the definition of real property tax, it being acknowledged by Tenant and Landlord that Proposition 13 was adopted by the voters of the State of California in the June 1978 election (“Proposition 13”)
and that assessments, taxes, fees, levies and charges may be imposed by governmental agencies for such services as fire protection, street, sidewalk and road maintenance, conservation, refuse removal and for
other governmental services formerly provided without charge to property owners or occupants, and, in further recognition of the decrease in the level and quality of governmental services and amenities as a
result  of  Proposition  13,  Taxes  shall  also  include  any  governmental  or  private  assessm ents  or  the  Building’s  or  Complex’s  contribution  towards  a  governmental  or  private  cost-sharing  agreement  for  the
purpose of augmenting or improving the quality of services and amenities normally provided by governmental agencies.  It is the intention of Tenant and Landlord that all such new and increased assessments,
taxes, fees, levies, and charges and all similar assessments, taxes, fees, levies and charges be included within the definition of Taxes for purposes of this Lease.  FOR PROPERTY TAX PURPOSES, TO
THE EXTENT ALLOWED BY LAW, TENANT WAIVES ALL RIGHTS TO PROTEST OR APPEAL THE APPRAISED VALUE OF THE PREMISES, AS WELL AS THE PROJECT AND
COMPLEX, AND ALL RIGHTS TO RECEIVE NOTICES OF REAPPRAISEMENT .  Tenant shall reimburse Landlord, as Additional Rent,  upon demand for any and all taxes required to be paid by
Landlord (except to the extent included in Taxes for the Complex by Landlord), excluding state, local and federal personal or corporate income taxes measured by the net income of Landlord from all sources,
capital stock, franchise and estate and inheritance taxes, whether or not now customary or within the contemplation of the parties hereto, when: (a) said taxes are measured by or reasonably attributable to the
cost or value of Tenant’s equipment, f urniture, fixtures and other personal property located in the Premises, or by the cost or value of any leasehold improvements made in or to the Premises by or for Tenant,
including the Tenant Improvements, to the extent the cost or value of such leasehold improvements exceeds the cost or value of a building standard build out as determined by Landlord regardless of whether
title to such improvements shall be vested in Tenant or Landlord; (b) said taxes are assessed upon or with respect to the possession, leasing, operation, management, maintenance, alteration, repair, use or
occupancy by Tenant of the Premises or any portion of the Complex used by Tenant in connection with this Lease; or (c) said taxes are assessed upon this transaction or any document to wh ich Tenant is a
party creating or transferring an interest or an estate in the Premises.

4.

Insurance.  Tenant shall pay all Insurance for the Building, and Tenant’s Proportionate Share of Insurance for the Complex for each year and partial year falling within the
Term.  Tenant shall pay Tenant’s Proportionate Share of Insurance in the same manner as provided above for Tenant’s Proportionate Share of Common Area Maintenance Costs.  “ Insurance” shall mean
property, liability and

151177627 v8

EXHIBIT C-3

 
other  insurance  coverages  carried  by  Landlord,  including  without  limitation  deductibles  and  risk  retention  programs  and  an  allocation  of  a  portion  of  the  cost  of  blanket  insurance  policies  maintained  by
Landlord and/or its affiliates, provided that such insurance deductibles or premiums shall not be in excess of that incurred by comparable landlords for comparable buildings in the Project’s market area.

5.

Common Area Maintenance, Tax and Insurance Statement.  By May 1 of each calendar year, or as soon thereafter as practicable, Landlord shall furnish to Tenant a
statement  of  Common Area  Maintenance  Costs,  Taxes,  and  Insurance  for  the  Building  and  the  Complex  for  the  previous  year,  adjusted  as  provided  in  Section  6  of  this  Exhibit  (the  “Common  Area
Maintenance, Tax and Insurance Statement”).  If Tenant’s estimated payments of Common Area Maintenance or Taxes or Insurance for the Building and the Complex under this Exhibit C for the year
covered  by  the  Common Area  Maintenance  Costs,  Tax  and  Insurance  Statement  exceed  Tenant’s  share  of  such  items  as  indicated  in  the  Common Area  Maintenance,  Tax  and  Insurance  Statement,  then
Landlord shall promptly credit or reimburse Tenant for such excess; likewise, if Tenant’s estimated payments of Common Area Maintenance, Taxes and Insurance under this  Exhibit C for such year are less
than Tenant’s share of such items as indicated in the Common Area Maintenance, Tax and Insurance Statement, then Tenant shall promptly pay Landlord such deficiency, notwithstanding that the Term has
expired and Tenant has vacated the Premises.

6.

Gross-Up.  With respect to any calendar year or partial calendar year in which the Complex is not occupied to the extent of 95% of the rentable area thereof, or Landlord is
not  supplying  services  to  95%  of  the  rentable  area  thereof,  the  portion  of  Common Area  Maintenance  Costs  for  the  Complex  for  such  period  which  vary  by  occupancy  shall,  for  the  purposes  hereof,  be
increased to the amount which would have been incurred had the Complex been occupied to the extent of 95% of the rentable area thereof and Landlord had been supplying services to 95% of the rentable
area thereof.

7.

Tenant’s Audit Right .  Upon Tenant’s written request given not more than ninety (90) days after Tenant’s receipt of the Common Area Maintenance, Tax and Insurance
Statement,  Landlord  shall  furnish  Tenant  with  such  reasonable  supporting  documentation  in  connection  with  said  Common  Area  Maintenance  Costs,  Taxes  and  Insurance  as  Tenant  may  reasonably
request.  Landlord shall provide said information to Tenant within thirty (30) days after Tenant’s written request therefor.  Within ninety (90) days after receipt of the Common Area Maintenance, Tax and
Insurance Statement by Tenant (the “Review Period”), if Tenant disputes the amount of Additional Rent set forth in the Common Area Maintenance, Tax and Insurance Statement, an independent certified
public  accountant  (which  accountant  (A)  is  a  member  of  a  nationally  or  regionally  recognized  accounting  firm  which  has  previous  experience  in  reviewing  financial  operating  records  of  landlords  of
comparable buildings, (B) shall not have provided primary accounting and/or lease administration services to Tenant in the past three (3) years, and (C) is not working on a contingency fee basis) designated
and  paid  for  by  Tenant,  may,  after  reasonable  notice  to  Landlord  and  at  reasonable  times,  inspect  Landlord’s  records  with  respect  to  the  Common Area  Maintenance,  Tax  and  Insurance  Statement  at
Landlord’s corporate offices, provided that Tenant is not in default under the Lease (subject to the applicable notice and cure periods).  In connection with such inspection, Tenant and Tenant’s agents must
agree in advance to abide by Landlord’s reasonable rules and procedures regarding such inspection, and shall execute a commercially reasonable confidentiality agreement regarding such inspection.  Such
inspection shall be completed in a timely manner but no later than thirty (30) days after the date Tenant’s accountant commences such inspection.  Any audit report prepared by Tenant’s auditors shall be
delivered concurrently to Landlord and Tenant within such thirty (30) day period.  Tenant’s failure to dispute the amount of Additional Rent set forth in any Common Area Maintenance, Tax and Insurance
Statement within the Review Period shall be deemed to be Tenant’s approval of such statement and Tenant, thereafter, waives the right or ability to dispute the amounts set forth in such statement.  If after
such inspection, Tenant still disputes such Additional Rent, a determination as to the proper amount may be made, at Tenant’s option and expense, by an independent certified public accountant who (x) is a
member of a nationally or regionally recognized accounting firm which has previous experience in reviewing financial operating records of landlords of comparable buildings, (y) is not working

151177627 v8

EXHIBIT C-4

 
on a contingency fee basis and (z) shall be mutually selected by Landlord and Tenant (the “Accountant”); provided that if such determination by the Accountant proves that Additional Rent for the applicable
Expense Year were overstated by more than five percent (5%), then the cost of the Accountant and the cost of such determination shall be paid for by La ndlord.  In addition, if such audit reveals that Landlord
has over-charged Tenant, then within thirty (30) days after the results of such audit are made available to Landlord, Landlord shall reimburse to Tenant the amount of such over-charge.  If the audit reveals that
the Tenant was under-charged, then within thirty (30) days after the results of such audit are made available to Tenant, Tenant shall reimburse to Landlord the amount of such under-charge.  Tenant agrees that
this Section 7 shall be the sole method to be used by Tenant to dispute the amount of any Common Area Maintenance Costs, Taxes and Insurance payable or not payable by Tenant pursuant to the terms of the
Lease, and Tenant hereby waives any other rights at law or in equity relating thereto.

Allowance (or the Additional Tenant Improvement Allowance, as such term is defined below) to Tenant unless Tenant makes a request for disbursement pursuant to the terms and conditions of  Section 2.2
below prior to that date which is nine (9) months after the Commencement Date, or (b) all or any portion of the HVAC Allowance or the Roof Allowance (as such terms are defined below) to Tenant unless
Tenant makes a request for disbursement pursuant to the terms and conditions of  Section 2.2.3 below prior to that date which is nine (9) months after the Commencement Date.  In no event shall Landlord be
obligated to make disbursements pursuant to this Work Letter in a total amount which exceeds the Tenant Improvement Allowance, the Additional Tenant Improvement Allowance, the Roof Allowance and
the HVAC Allowance.  Tenant shall not be entitled to receive any cash payment or credit against Rent or otherwise for any unused portion of the Tenant Improvement Allowance (or the Additional Tenant

Concurrent with Tenant’s execution of this Lease, Tenant shall deposit with an escrow company (“Escrowee”) mutually selected by Landlord and
Tenant an amount equal to One Hundred Dollars ($100.00) per rentable square foot of the Premises (i.e., Eight Million Seven Hundred Sixty-Nine Thousand Five Hundred Dollars ($8,769,500.00) (“Tenant

151177627 v8

EXHIBIT D-1

the modified Base Rent schedule as a result thereof, which confirmation Tenant shall acknowledge by executing a copy of the confirmation and returning it to Landlord.  If Landlord fails to sign and return the
confirmation to Landlord within ten (10) days of receipt thereof from Landlord, the confirmation as sent by Landlord shall be deemed to have correctly set forth the modified Base Rent schedule.  Failure of
Landlord to send such confirmation shall have no effect on the modified Base Rent schedule.

In  addition  to  the  Tenant  Improvement Allowance,  Tenant  shall  be  entitled  to  a  one-time  HVAC  allowance  (the  “ HVAC Allowance ”)  in  the

SECTION 3

CONSTRUCTION DRAWINGS

3.1

Selection  of Architect/Construction  Drawings.    Tenant  shall  retain  the  architect/space  planner  (the  “Architect”)  approved  by  Landlord,  which  approval  shall  not  be
unreasonably withheld and shall be granted or denied within three (3) Business Days upon request, to prepare the Construction Drawings.  Landlord’s failure to respond within such three (3) Business Day
period  shall  be  deemed  approval  by  Landlord.    Tenant  shall  retain  the  engineering  consultants  (the  “Engineers”)  approved  by  Landlord,  which  approval  shall  not  be  unreasonably  withheld  and  shall  be
granted  or  denied  within  three  (3)  Business  Days  upon  request,  to  prepare  all  plans  and  engineering  working  drawings  relating  to  the  structural,  mechanical,  electrical,  plumbing,  HVAC,  life  safety,  and
sprinkler work in the Premises.  Landlord’s failure to respond within such three (3) Business Day period shall be deemed approval by Landlord.  The plans and drawings to be prepared by Architect and the
Engineers hereunder shall be known collectively as the “Construction Drawings”.  All Construction Drawings shall comply with the drawing format and specifications reasonably determined by Landlord,
and shall be subject to Landlord’s approval

151177627 v8

EXHIBIT D-4

 
within five (5) Business Days after delivery to Landlord.  In the event Landlord fails to respond within such five (5) Business Day period, Tenant shall send a reminder notice to Landlord and Landlord’s failure
to respond to the reminder notice within two (2) Business Days after receipt thereof shall be deemed approval by Landlord.  Tenant and Architect shall verify, in the field, the dimensions and conditions as
shown on the relevant portions of the base building plans, and Tenant and Architect shall be solely responsible for the same, and Landlord  shall have no responsibility in connection therewith.  Landlord’s
review of the Construction Drawings as set forth in this Section 3, shall be for its sole purpose and shall not imply Landlord’s review of the same, or obligate Landlord to review the same, for quality, design,
Code compliance or other like matters.  Accordingly, notwithstanding that any Construction Drawings are reviewed by Landlord or its space planner, architect, engineers and consultants, and notwithstanding
any advice or assistance which may be rendered to Tenant by Landlord or Landlord’s space planner, architect, engineers, and consultants, Landlord shall have no liability whatsoever in connection therewith
and shall not be responsible for any omissions or errors contained in the Construction Drawings.

3.2

Final Space Plan.  Tenant shall supply Landlord with four (4) copies signed by Tenant of its final space plan for the Premises before any architectural working drawings or
engineering  drawings  have  been  commenced.    The  final  space  plan  (the  “Final  Space  Plan”)  shall  include  a  layout  and  designation  of  all  offices,  rooms  and  other  partitioning,  their  intended  use,  and
equipment to be contained therein.  Landlord may request clarification or more specific drawings for special use items not included in the Final Space Plan.  Landlord shall reasonably advise Tenant within
five (5) Business Days after Landlord’s receipt of the Final Space Plan for the Premises if the same is unsatisfactory or incomplete in any respect and the manner in which the Final Space Plan is unsatisfactory
or incomplete.  If Tenant is so advised, Tenant shall promptly (i) cause the Final Space Plan to be revised to correct any deficiencies or other matters Landlord may reasonably require, and (ii) deliver such
revised Final Space Plan to Landlord.  In the event Landlord fails to respond within such five (5) Business Day period, Tenant shall send a reminder notice to Landlord and Landlord’s failure to respond to the
reminder notice within two (2) Business Days after receipt thereof shall be deemed approval by Landlord.

3.3

Final  Working  Drawings.   After  the  Final  Space  Plan  has  been  approved  by  Landlord  and  Tenant,  Tenant  shall  promptly  cause  the Architect  and  the  Engineers  to
complete  the  architectural  and  engineering  drawings  for  the  Premises,  and  cause  the Architect  to  compile  a  fully  coordinated  set  of  architectural,  structural,  mechanical,  electrical  and  plumbing  working
drawings in a form which is complete to allow subcontractors to bid on the work and to obtain all applicable permits for the Tenant Improvements (collectively, the “ Final Working Drawings”), and shall
submit the same to Landlord for Landlord’s approval.  Tenant shall supply Landlord with four (4) copies signed by Tenant of such Final Working Drawings.  Landlord  shall reasonably advise Tenant within
five (5) Business Days after Landlord’s receipt of the Final Working Drawings for the Premises if the same is unsatisfactory or incomplete in any respect and the manner in which the Final Working Drawings
is unsatisfactory or incomplete.  If Tenant is so advised, Tenant shall promptly (i) revise the Final Working Drawings in accordance with such review and any disapproval of Landlord in connection therewith,
and (ii) deliver such revised Final Working Drawings to Landlord.  In the event Landlord fails to respond within such five (5) Business Day period, Tenant shall send a reminder notice to Landlord and
Landlord’s failure to respond to the reminder notice within two (2) Business Days after receipt thereof shall be deemed approval by Landlord.

3.4

Approved Working Drawings.  The Final Working Drawings shall be approved by Landlord in accordance with Section 3.3 above (the “Approved Working Drawings”)
prior to the commencement of construction of the Tenant Improvements by Tenant.  After approval by Landlord of the Final Working Drawings, Tenant shall promptly submit the same to the appropriate
governmental authorities for all applicable building permits.  Tenant hereby agrees that neither Landlord nor Landlord’s consultants sha ll be responsible for obtaining any building permit or certificate of
occupancy for the Tenant Improvements and that obtaining the same shall be Tenant’s responsibility; provided, however, that

151177627 v8

EXHIBIT D-5

 
Landlord shall cooperate with Tenant in executing permit applications and performing other ministerial acts reasonably necessary to enable Tenant to obtain any such permit or certificate of occupancy.  No
changes,  modifications  or  alterations  in  the Approved  Working  Drawings  may  be  made  without  the  prior  written  cons ent  of  Landlord,  which  consent  shall  not  be  unreasonably  withheld,  conditioned,  or
delayed; provided that Landlord may withhold its consent, in its sole discretion, to any change in the Approved Working Drawings, if such change would result in an Over Allowance  Amount (as  defined
below), and Tenant does not agree in writing to pay such Over Allowance Amount.

3.5

Changes to the Approved Working Drawings.  Any changes to the Approved Working Drawings (each, a “Change”) shall be requested and instituted in accordance with

the provisions of this Section 3.5 and shall be subject to the written approval of the non-requesting party in accordance with this Work Letter.

3.5.1

Change Request.  Either Landlord or Tenant may request Changes after Landlord approves the Final Working Drawings by notifying the other
party thereof in writing in substantially the same form as the AIA standard change order form (a “ Change Request”), which Change Request shall detail the nature and extent of any requested Changes and
any modification of the Approved Working Drawings, as applicable, necessitated by the Change.  If the nature of a Change requires revisions to the Approved Working Drawings, then the requesting party
shall be solely responsible for the cost and expense of such revisions and any increases in the cost of the Tenant Improvements as a result of such Change.  Change Requests shall be signed by the requesting
party’s representative as set forth in Sections 5.1 and 5.2 herein.  Landlord shall only request a Change if it reasonably believes that such Change is necessary to comply with applicable Laws or to prevent a
material  adverse  impact  on  the  Building’s  Systems;  provided,  however,  that  Landlord  shall  not  be  responsible  for  the  cost  and  expense  of  such  revision  and/or  any  increase  in  the  cost  of  the  Tenant
Improvements as a result of such Change.

Approval of Changes.  All Change Requests shall be subject to the other party’s prior written approval, which approval shall not be unreasonably
withheld, conditioned or delayed.  The non-requesting party shall have three (3) Business Days after receipt of a Change Request to notify the requesting party in writing of the non-requesting party’s decision
either  to  approve  or  object  to  the  Change  Request.    If  the  non-requesting  party  fails  to  respond  within  such  three  (3)  Business  Day  period,  the  requesting  party  shall  send  a  reminder  notice  and  the  non-
requesting party’s failure to respond to the reminder notice within two (2) Business Days after receipt thereof shall be deemed approval by the non-requesting party.

3.5.2

4.1

Tenant’s Selection of Contractor and Tenant’s Agents.

SECTION 4

CONSTRUCTION OF THE TENANT IMPROVEMENTS

The Contractor.  A general contractor shall be retained by Tenant to construct the Tenant Improvements.  Such general contractor (“Contractor”)
shall be subject to Landlord’s approval, which approval shall not be unreasonably withheld and shall be granted or denied within three (3) Business Days upon request.  Landlord’s failure to respond within
such three (3) Business Day period shall be deemed approval by Landlord.

4.1.1

Tenant’s Agents.  A list of all subcontractors, laborers, materialmen, and suppliers used by Tenant (such subcontractors, laborers, materialmen,
and  suppliers,  and  the  Contractor  to  be  known  collectively  as  “Tenant’s Agents ”)  must  be  provided  to  the Landlord,  which  Tenant’s Agents  shall  all  be  licensed,  in  good  standing  and  have  a  first-class
reputation in their respective area of expertise.  In any

4.1.2

151177627 v8

EXHIBIT D-6

 
event,  Tenant  must  contract  with  Landlord’s  base  building  subcontractors  for  any  mechanical,  electrical,  plumbing,  life  safety,  structural,  heating,  ventilation,  and air  conditioning work  in  the
Premises.  Tenant’s Agents shall all be union labor in compliance with the master labor agreements existing between trade unions and the local chapter of the Associated General Contractors of America.

4.2

Construction of Tenant Improvements by Tenant’s Agents.

4.2.1

Cost Budget.  Prior to the commencement of the construction of the Tenant Improvements, and after Tenant has accepted all bids for the Tenant
Improvements, Tenant shall provide Landlord with a written detailed cost breakdown (the “ Final Costs Statement”), by trade, of the final costs to be incurred, or which have been incurred, as set forth more
particularly in Section 2.2.1.1 through 2.2.1.8 above, in connection with the design and construction of the Tenant Improvements to be performed by or at the direction of Tenant or the Contractor (which costs
form a basis for the amount of the construction contract with the Contractor, if any (the “Final Costs”).  Tenant shall be responsible for all the Final Costs, and Tenant shall pay all such costs directly to the
Contractor or other party requesting payment as and when due, provided that nothing contained in this sentence shall be construed to waive Tenant’s right to receive the Tenant Improvement Allowance, the
Additional Tenant Improvement Allowance, the HVAC Allowance or the Roof Allowance.  In addition, to the extent the Final Costs  exceed the Tenant Improvement Allowance and the Additional Tenant
Improvement Allowance (“Over Allowance Amount”), Tenant shall pay, concurrently with each disbursement by Landlord pursuant to Section 2.2.2, a pari passu portion of the Tenant Improvement costs
subject to such request, equal to the ratio obtained by dividing the Over Allowance Amount by the Final Costs (“ Pro Rata Share”), multiplied by portion of the Tenant Improvement costs subject to such
request.  For  purposes  of  illustration  only,  if  the  Final  Costs  are  $500,000,  the  total  allowance  payable  by  Landlord  (i.e.,  the  Tenant  Improvement Allowance  and  the Additional  Tenant  Improvement
Allowance)  is  $250,000,  and  the  applicable  bills  and  invoices  submitted  to  Landlord  for  a  disbursement  pursuant  to Section 2.2.2  is  $100,000,  Landlord  would  disburse  $50,000  ($250,000/$500,000  x
$100,000), and Tenant would pay the remaining $50,000.  In the event that, after the Final Costs have been delivered by Landlord to Tenant, the costs relating to the design and construction of the Tenant
Improvements shall change, any additional costs necessary to such design and construction in excess of the Final Costs shall, to the extent they exceed the remaining balance of the Tenant Improvement
Allowance, be paid by Tenant to Landlord in the same method as the payment by Tenant of the Over-Allowance Amount set forth herein.

4.2.2

Tenant’s Agents.

4.2.2.1

Landlord’s General Conditions for Tenant’s Agents and Tenant Improvement Work .  Tenant’s and Tenant’s Agents’

necessary  thereto,  and  Tenant’s Agents  shall  use  commercially  reasonable  efforts  to  adhere to such corrected schedule; and (iii)  Tenant  shall  abide  by  all  reasonable rules  made  and  provided  to  Tenant  in
writing by Landlord’s Building contractor or Landlord’s Building manager with respect to the use of freight, loading dock and service elevators (provided that such rules shall not include additional charge for
the use of freight, loading dock and service elevators or storage of materials), storage of materials, coordination of work with the contractors of other tenants, and any other matter in connection with this Work
Letter, including, without limitation, the construction of the Tenant Improvements.

4.2.2.2

Coordination  Fee.    Tenant  shall  pay  a  logistical  coordination  fee  (the  “Coordination  Fee”)  to  Landlord  in  an

amount equal to the product of (i) one percent (1%), and (ii) the

151177627 v8

EXHIBIT D-7

 
sum  of  the  Tenant  Improvement Allowance,  the  Over Allowance Amount,  as   such  amount  may  be  increased  hereunder,  and  any  other  amounts  expended  by  Tenant  in  connection  with  the  design  and
construction of the Tenant Improvements, which Coordination Fee shall be for services relating to the coordination of the construction of the Tenant Improvements.  In addition to the Coordination Fee and
other amounts payable by Tenant hereunder, Tenant shall reimburse Landlord for reasonable amounts paid by Landlord in connection with the review of Tenant’s plans and drawings as referenced in Section 3
above, which amounts shall be charged against the Tenant Improvement Allowance.

Indemnity.    Tenant’s  indemnity  of  Landlord  as  set  forth  in  the  Lease  shall  also  apply  with  respect  to  any  and  all
costs, losses, damages, injuries and liabilities related in any way to any act or omission of Tenant or Tenant’s Agents, or anyone directly or indirectly employed by any of them, or in connection with Tenant’s
non‑payment of any amount arising out of the Tenant Improvements and/or Tenant’s disapproval of all or any portion of any request for payment.  Such indemnity by Tenant, as set forth in the Lease, shall
also apply with respect to any and all costs, losses, damages, injuries and liabilities related in any way to Landlord’s performance of  any ministerial acts reasonably necessary (i) to permit Tenant to complete
the Tenant Improvements, and (ii) to enable Tenant to obtain any building permit or certificate of occupancy for the Premises; provided, however, that nothing contained in this Work Letter shall be deemed to
indemnify Landlord from or against liability caused by Landlord’s negligence or willful misconduct.

Insurance Requirements.

  All  of  Tenant’s  Agents  shall  carry  worker’s
compensation insurance covering all of their respective employees, and shall also carry commercial general liability insurance, and such other coverages as are required in Exhibit I to the Lease, all with limits,

4.2.2.4.1

Special Coverages.    Tenant  shall  carry  “Builder’s All  Risk”  insurance  in  an
amount approved by Landlord covering the construction of the Tenant Improvements, and such other insurance as Landlord may require, it being understood and agreed that the Tenant Improvements shall be

Landlord, and in form and with companies as are required to be carried by Tenant as set forth in the Lease.

4.2.2.4.2

General Terms.  Certificates for all insurance carried pursuant to this Section
4.2.2.4 shall be delivered to Landlord before the commencement of construction of the Tenant Improvements and before the Contractor’s equipment is moved onto the site.  All such policies of insurance must
contain a provision that the company writing said policy will give Landlord thirty (30) days’ prior written notice of any cancellation or lapse of the effective date or any reduction in the amounts of such
insurance.  In the event that the Tenant Improvements are damaged by any cause during the course of the construction thereof, Tenant shall immediately repair the same at Tenant’s sole cost and expense.  All
policies carried under this Section 4.2.2.4 shall insure Landlord and Tenant, as their interests may appear, as well as Contractor and Tenant’s Agents, and shall name as additional insureds all Landlord Parties
(as defined in the Lease).  All insurance maintained by Tenant’s Agents shall preclude subrogation claims by the insurer against anyone insured thereunder.  Such insurance shall provide that it is primary
insurance  as  respects  the  Landlord  Parties  and  that  any  other  insurance  maintained  by  Landlord  Parties  is  excess  and  noncontributing  with  the  insurance  required  hereunder.    The  requirements  for  the
foregoing insurance shall not derogate from the provisions for indemnification of Landlord by Tenant under Section 4.2.2.3 of this Work Letter.

4.2.3

4.2.4

Inspection  by  Landlord.   Landlord  shall  have  the  right  to  inspect  the  Tenant  Improvements  during  normal  business  hours  upon  reasonable
advance notice, provided however, that Landlord’s failure to inspect the Tenant Improvements shall in no event constitute a waiver of any of Landlord’s rights hereunder nor shall Landlord’s inspection of the
Tenant Improvements constitute Landlord’s approval of the same.  Should Landlord disapprove any portion of the Tenant Improvements, Landlord shall notify Tenant in writing of such disapproval and shall
specify the items disapproved.  Any defects or deviations in, and/or disapproval by Landlord of, the Tenant Improvements shall be rectified by Tenant at no expense to Landlord, provided however, that in the
event Landlord determines that a defect or deviation exists or disapproves of any matter in connection with any portion of the Tenant Improvements and such defect, deviation or matter might adversely affect
the mechanical, electrical, plumbing, heating, ventilating and air conditioning or life safety systems of the Building, the structure or exterior appearance of the Building or any other tenant’s use of such other
tenant’s leased premises, and Tenant fails to commence to remedy the same within thirty (30) days after Landlord’s written notice thereof or fails to diligently execute to completion, Landlord may, take such
action as Landlord deems reasonably necessary, at Tenant’s expense and without incurring any liability on Landlord’s part, to correct any such defect, deviation and/or matter, including, without limitation,
causing the cessation of performance of the construction of the Tenant Improvements until such time as the defect, deviation and/or matter is corrected to Landlord’s reasonable satisfaction.

4.2.5

Meetings.   Commencing  upon  the  execution  of  the  Lease,  Tenant  shall  hold weekly  meetings  at  a  reasonable  time,  with  the Architect  and  the

Agents shall attend such meetings. In addition, minutes shall be taken at all such meetings, a copy of which minutes shall be promptly delivered to Landlord.  One such meeting each month shall include the
review of Contractor’s current request for payment.

Completion to be recorded in the office of the Recorder of the County in which the Building is located in accordance with Section 3093 of the Civil Code of the State of California or any successor statute, and
shall furnish a copy thereof to Landlord upon such recordation.  If Tenant fails to do so, Landlord may execute and file the same on behalf of Tenant as Tenant’s agent for such purpose, at Tenant’s sole cost
and expense.  At the conclusion of construction, (i) Tenant shall cause the Architect and Contractor (A) to update the Approved Working Drawings as necessary to reflect all changes made to the Approved
Working Drawings during the course of construction, (B) to certify to the best of their knowledge that the “record set” of as built drawings are true and correct, which certification shall survive the expiration

notice to Tenant, shall have full authority and responsibility to act on behalf of the Landlord as required in this Work Letter.

5.3

5.4

Tenant’s Lease Default.    Notwithstanding  any  provision  to  the  contrary  contained  in  the  Lease,  if  an  Event of  Default by  Tenant  of  this  Work  Letter  or  the  Lease  has
occurred at any time on or before the Substantial Completion of the Tenant Improvements, then (i) in addition to all other rights and remedies granted to Landlord pursuant to the Lease, at law and/or in equity,
Landlord shall have the right to withhold payment of all or any portion of the Tenant Improvement Allowance and/or Landlord may cause Contractor to cease the construction of the Tenant Improvements (in
which case, Tenant shall be responsible for any delay in the Substantial Completion of the Tenant Improvements caused by such work stoppage), and (ii) all other obligations of Landlord under the terms of
this Work Letter shall be forgiven until such time as such default is cured pursuant to the terms of the Lease  (in which case, Tenant shall be responsible for any delay in the Substantial Completion of the
Premises caused by such inaction by Landlord).  In addition, if the Lease is terminated prior to the Commencement Date, for any reason due to an Event of Default by Tenant as described in Section 17 of the
Lease or under this Work Letter, in addition to any other remedies available to Landlord under the Lease, at law and/or in equity, Tenant shall pay to Landlord, as Additional R ent under the Lease, within five

Improvements” shall mean completion of construction of the Tenant Improvements in the Premises pursuant to the Approved Working Drawings, with the exception of any punch list items.

5.5

Landlord Caused Delays.  The Commencement Date shall be extended on a day-to-day basis by the number of days of actual delay of the Substantial Completion of the

151177627 v8

EXHIBIT D-10

 
Landlord Caused Delay actually causes the Substantial Completion of the Tenant Improvements to occur after December 1, 2018.  As used in this Work Letter, “Landlord Caused Delay” shall mean delays to
the  extent  resulting  from  the  acts  or  omissions  of  Landlord,  its  agents,  employees  or  contractors,  including,  but  not  limited  to:  (i)  failure  of  Landlord  to  timely  approve  or  disapprove  any  Construction
Drawings  or  any  other  matter  that  requires  Landlord’s  approval  within  the  time  periods  set  forth  in  this  Work  Letter;  (ii)  material  and  unreasonable  interference  by  Landlord,  its  agents,  employees  or

Work Letter).

No Landlord Caused Delay shall be deemed to have occurred unless and until Tenant has provided written notice to Landlord specifying the action or inaction that Tenant
contends constitutes a Landlord Caused Delay.  If such action or inaction is not cured within one (1) Business Day after receipt of such notice, then a Landlord Caused Delay shall be deemed to have occurred
commencing as of the date such notice is received and continuing for the number of days the design and construction of the Tenant Improvements was in fact delayed as a direct result of such action or
inaction.

RENEWAL OPTION

If Tenant has not committed a default (which is not cured by the time Tenant exercises its option to renew), and Tenant is occupying the entire Premises at the time of such election (provided
that Tenant shall be deemed to occupy the entire Premises even if a portion of the Premises is occupied by a Permitted Transferee), Tenant may renew this Lease for two (2) additional period(s) of five (5)
years  each,  by  delivering  written  notice  of  the  exercise  thereof  to  Landlord  not  earlier  than  fifteen  (15)  months  nor  later  than  nine  (9)  months  before  the  expiration  of  the  then-current  Term  (“Tenant’s
Election Notice”).  Any extension of the Term shall be on all the same terms and conditions as this Lease, except as expressly set forth herein. The Base Rent payable for each month during such extended
Term  shall  be  equal  to  ninety  percent  (90%)  of  the  prevailing  rental  rate  (the  “Prevailing  Rental  Rate”),  at  the  commencement  of  such  extended  Term,  for  renewals  of  space  in  the  Complex  and  in
comparable buildings with comparable life science tenant(s) and comparable build-out (containing the systems and improvements present in the Premises including similar concentration of lab space) located
within  North  San  Mateo  County,  California,  of  equivalent  quality,  size,  utility,  age,  level  of  finish,  proximity  to  amenities  and  public  transit,  and  location,  with  the  length  of  the  extended  Term,  any
concessions offered to new tenants, (such as free rent, tenant improvement allowances and moving allowances), whether or not there will be a charge for parking, and the credit standing of Tenant to be taken
into account (such factors, the “Relevant Factors”).  Within fifteen (15) days after receipt of Tenant’s Election Notice, Landlord shall deliver to Tenant written notice of the Prevailing Rental Rate and shall
advise Tenant of the required adjustment to Base Rent, if any.  Tenant shall, within ten (10) days after receipt of Landlord’s notice, notify Landlord in writing whether Tenant accepts or rejects Landlord’s
determination of the Prevailing Rental Rate.  If Tenant timely notifies Landlord that Tenant accepts Landlord’s determination of the Prevailing Rental Rate, then, on or before the commencement date of the
extended Term, Landlord and Tenant shall execute an amendment to this Lease extending the Term on the same terms provided in this Lease, except as follows:

(a)

(b)

(c)

Base Rent and the annual increase shall be adjusted to the Prevailing Rental Rate;

Tenant shall have no further renewal option after exercising the second renewal option unless expressly granted by Landlord in writing; and

Landlord shall lease to Tenant the Premises in their then-current condition, and Landlord shall not provide to Tenant any allowances (e.g., moving allowance, construction

allowance, and the like) or other tenant inducements.

If by the date thirty (30) days following delivery of Tenant’s Election Notice, Landlord and Tenant have not agreed in writing as to the amount of the Base Rent, the parties shall determine the
projected Prevailing Rental Rate in accordance with the following procedure (which procedure is herein referred to as the “Three-Appraiser Method”).  Landlord and Tenant shall each appoint one (1) real
estate appraiser, and the two (2) so appointed shall select a third.  Said real estate appraisers shall each be licensed in the state in which the Premises is located, specializing in the field of commercial real
estate in North San Mateo County, California, having no less than ten (10) years’ experience in such field, unaffiliated with either Landlord or Tenant and recognized as ethical and reputable within their
field.  Landlord and Tenant agree to make their appointments promptly within ten (10) days after expiration of the thirty (30) day negotiation period, or sooner if mutually agreed upon.  The two (2) appraisers
selected by Landlord and Tenant shall promptly select a third appraiser within fifteen (15) days after they both have been appointed, and each appraiser, within fifteen (15) days after the third appraiser is
selected, shall submit his or her determination of the then projected Prevailing Rental Rate after taking into account all the Relevant Factors.  Such third appraiser shall choose one of the two (2) Prevailing
Rental Rates submitted by the parties which most closely represents the projected prevailing market rate after taking into account all the Relevant Factors.  

151177627 v8

EXHIBIT H-1

 
Such Prevailing Rental Rate chosen by the appraiser shall be final and binding upon the parties.  If either Landlord or Tenant fails to appoint an appraiser within the time period specified in this paragraph, the
appraiser appointed by one of them shall reach a decision, notify Landlord and Tenant thereof, and such appraiser’s decis ion shall be binding upon Landlord and Tenant.  Each party shall pay the fees and
expenses of the appraiser appointed by or on behalf of it, and each shall pay one-half of the fees and expenses of the third appraiser.

Parties shall confirm the parties’ acceptance of the determination of the Prevailing Rental Rate by executing an amendment to this Lease memorializing the same within ten (10) days of such
determination (herein the “Extension Amendment ”).  Failure to execute and deliver the Extension Amendment within such 10-day period shall not affect the enforceability of the extension exercised by
Tenant.

Notwithstanding anything in the foregoing to the contrary, at Landlord’s option, and in addition to all of Landlord’s remedies under this Lease, at law or in equity, the right to extend the Term
of this Lease hereinabove granted to Tenant shall not be deemed to be properly exercised if, as of the date Tenant exercises its extension right or on the scheduled commencement date for the applicable option
term, Tenant is in default under this Lease beyond any applicable notice and cure period.  Further, Tenant’s rights under this Exhibit shall terminate if (1) this Lease or Tenant’s right to possession of the
Premises is terminated, (2) Tenant assigns any of its interest in this Lease or sublets any portion of the Premises to any party other than a Permitted Transferee, or (3) Tenant fails to timely exercise its option
under this Exhibit, time being of the essence with respect to Tenant’s exercise thereof.

CONTRACTOR INSURANCE REQUIREMENTS

I-1.

The following defined terms apply for purposes of this Exhibit. Other capitalized terms used but not defined in this Exhibit will have the  meanings given to such terms in the
Lease  to  which  this  Exhibit  is  attached.  “Work”  means  the  applicable  work  to  be  performed  at  the  Premises,  and  to  which  the  requirements  of  this  Exhibit  relate  pursuant  to  the  Lease.
“Contractor”  means  Tenant’s  general  contractor  with  respect  to  the  Work.  “ Subcontractors”  means  any  person  retained  by  the  Contractor  as  an  independent  contractor  to  provide  labor,
materials, equipment, or services necessary to complete a specific portion of the Work, and their sub-subcontractors of every tier. “ Landlord Parties” means Landlord; Landlord’s property
manager with respect to the Premises; Landlord’s Mortgagee; other entities or individuals Landlord may designate from time to time to be included as additional insureds (e.g., by requiring that
they be listed as additional insureds on certificates of insurance); the successors and assigns, and direct and indirect affiliates, of each of the foregoing; and, with respect to each of the foregoing,
its shareholders, trustees, beneficiaries, managers, officers, directors, employees, and agents.

I-2.

Tenant shall require its Contractor to maintain insurance that satisfies the following requirements (except Landlord may reasonably adjust the minimum limits provided herein

from time to time time):
(a)

Commercial  general  liability  insurance  on  the  current  ISO  CG  00  01  form  or  an  equivalent  occurrence  form  that  (i)  has  limits  of  not  less  than  the  greater  of  (A)  $1,000,000  each
occurrence, $1,000,000 personal and advertising injury, $2,000,000 general aggregate  (per-project),  and  $2,000,000  products-completed  operations  aggregate  and  (B)  the  limits  the
Contractor actually carries, and (ii) includes the Landlord Parties as additional insureds on a primary and noncontributing basis, providing them with coverage at least as broad as that
given  to  the  named  insured.  The  Contractor  shall  maintain  its  products-completed  operations  coverage  for  at  least  five  years  after  completion  of  the  Work,  and  shall  include  the
Landlord Parties as additional insureds on a primary and non-contributing basis during this period.
Business auto insurance covering any auto (including owned, hired, and non-owned autos), with a limit of not less than $1,000,000 each accident.

(b)
(c) Workers compensation and employers liability insurance for all persons that perform Work for the Contractor. The workers compensation insurance must fulfill applicable statutory

(d)

(e)

requirements. The employers liability insurance must have limits of not less than $1,000,000 each accident, $1,000,000 each employee, and $1,000,000 policy limit.
Commercial  excess  or  umbrella  liability  insurance  on  a  “follow  form”  basis,  with  a  limit  of  not  less  than  $10,000,000  each  occurrence  and  annual  aggregate.  This  insurance  must
provide that aggregate limits of liability apply separately with respect to the Work. Notwithstanding the specified minimum limits in this Section I-2 for primary commercial general
liability, business auto, and employers liability insurance and the separate specified minimum limit for commercial excess or umbrella liability insurance, in each case this Section I-2
is to be construed as requiring only the combined primary and excess/umbrella minimum limit and that combined minimum limit may be achieved with any combination of primary
and excess or umbrella insurance.
Professional liability insurance, if the Work includes any professional services (including any design-build component of the Work), with limits of not less than $1,000,000 each claim
and

151177627 v8

EXHIBIT I-1

 
 
(f)

$1,000,000  annual  aggregate.  If  the  Contractor  performs  the  professional  services,  then  it  shall  carry  this  insurance;  if  a  Subcontractor  performs  the  services,  then  Contractor  shall
require the Subcontractor to carry this insurance.
Property insurance for job trailers, machinery, tools, equipment, property of a similar nature owned or leased by the Contractor or Subcontractors and not destined to become a part of
the completed construction, and the Contractor must waive, and require its Subcontractors (including lessors of equipment) to waive, all claims against the Landlord Parties for loss or
damage to these items, regardless of the cause.

I-3.

Tenant shall require the Contractor to waive all rights against the Landlord Parties to the extent any damage is covered by insurance  maintained by the Contractor, or is
attributable to any deductible or self-insured retention relating to insurance maintained by the Contractor, and shall ensure that its policies permit this waiver of subrogation by endorsement or
otherwise.

I-4.

Tenant  shall  require  the  Contractor,  by  written  agreement,  to  require  its  Subcontractors  to  maintain  the  insurance  and  make  the  waivers  required  of  the  Contractor  in  this
Exhibit,  except  that  with  respect  to  Subcontractors’  insurance  Tenant  may  permit  its  Contractor,  with  Landlord’s  consent,  to  reduce  or  waive  the  commercial  excess  or  umbrella  liability
insurance requirement in circumstances where such reduction or waiver for that Subcontractor (given its scope of Work) is commercially reasonable and customary. Tenant shall require the
Contractor to obtain certificates of insurance from its Subcontractors evidencing the insurance required under this Exhibit.

I-5.

All  insurance  policies  required  under  this  Exhibit  must  be  issued  by  reputable,  financially  sound  co mpanies  that  have  an A.M.  Best  rating  of A-  VIII  or  better.  Before
commencement of the Work, Tenant shall require the Contractor to provide to Landlord a certificate of insurance evidencing the required insurance and, if requested, the Contractor’s additional
insured endorsement. Tenant shall require the Contractor to provide an updated certificate of insurance before the expiration of the term of any required coverage, and otherwise upon request.
Tenant shall require all policies of insurance required under this Exhibit to contain a provision that the company writing said policy will give Landlord 30’ days’ prior written notice of any
cancellation or lapse of the effective date or any reduction in the amounts of such insurance. Tenant shall require the Contractor to provide copies of policies required under this Exhibit if
requested.

for the Property as follows:

Section 1.

Grant of Right of First Offer.

(hereinafter, the “Premises”) except in accordance with the provisions of this Agreement, subject to the conditions set forth in Exhibit M to the Lease.

1.1.

Transfer.    During  the  ROFO  Period,  Owner  shall  not  Transfer  (as  hereinafter  defined)  its  fee  interest  in  the  Property

Procedure.    Owner  shall  give  notice  to  Offeree  (the  “Offer  Notice”)  when  Owner  desires  to
Transfer the Premises to a third party (i.e., whether or not Owner has received a third party offer it elects to pursue).  The Offer Notice shall describe Owner’s proposed Transfer and all of the economic and
non-economic terms and conditions applicable to Offeree’s purchase of the Premises.  For purposes of this Agreement, the term “economic terms” shall be defined to mean only those economic terms that are
to be accounted for on a final escrow closing/settlement statement.  The “non-economic terms” shall be on terms as set forth in the form purchase and sale agreement (“Purchase

(a)

151177627 v8

EXHIBIT M-1-1

 
 
Agreement”) to be agreed upon by the parties hereto in their commercially reasonable determination (collectively, the “Offer Terms”).

Procedure for Acceptance.  Within ten (10) business days after delivery of the Offer Notice (the
“Offer Election Date”), Offeree shall deliver written notice to Owner (“Offeree’s Election Notice”) pursuant to which Offeree shall elect either to (i) purchase the Premises pursuant to the Offer Terms set
forth in the Offer Notice, or (ii) decline to purchase the Premises, in which event this Agreement and the ROFO set forth herein and in the Lease shall thereupon terminate and be of no further force or effect
(unless reinstated pursuant to the below described terms).  In the event Offeree elects to purchase the Premises, Offeree shall deliver with Offeree’s Election Notice to Owner a signed Purchase Agreement
with the Offer Terms set forth.  If Offeree does not so respond in writing to Owner’s Offer Notice by the Offer Election Date, Offeree shall be irrevocably deemed to have elected the option described in clause
(ii) above, in which event Offeree’s ROFO set forth herein and in the Lease shall thereupon terminate, subject to reinstatement pursuant to Section 1.2 below.

(b)

Owner’s Response.  If Offeree elects to purchase the Premises, then within five (5) business days
after receipt of Offeree’s Election Notice, Owner shall return to Offeree and Escrow Holder as identified in the Purchase Agreement a signed counterpart of the Purchase Agreement with the Offer Terms
incorporated therein.  If the parties have not mutually executed and delivered the Purchase Agreement within thirty (30) days following Offeree’s Election Notice, or if Offeree does not elect to purchase the
Premises, Owner may, at its election, and subject to the terms of this paragraph, during the twelve (12) month period following the date of the Offer Notice, enter into a letter of intent or purchase and sale
agreement to sell and thereby Transfer the Premises described in the Offer Notice to any entity at such economic and non-economic terms as are acceptable to Owner and such third party purchaser without
any Material Modification (as described in Section 1.2 below) to the Offer Terms.  If Owner does not Transfer the Premises described in the Offer Notice within the above described twelve (12) month period
(and  subject  to Section 1.2 below), then Owner shall submit to Offeree a new Offer Notice with respect to the Premises prior to selling the Premises upon terms and conditions set forth in the new Offer
Notice.

(c)

Nothing herein shall prevent or restrict Offeree from making a subsequent
offer for the Premises or from participating as a bidder in Owner’s marketing of the Premises.  Owner shall use its reasonable efforts, without any liability for failure to do so, to furnish Offeree with the
marketing information related to the Premises.

(i)

Material Modification.  For purposes of this Agreement, a Material Modification shall mean any decrease of more than
ten percent (10%) in the economic terms (or change in cost allocations of the Purchase Agreement that would have the same effect).  If the Owner’s proposed Transfer is at economic terms of ninety percent
(90%) or more than proposed Offer Terms to Offeree set forth in the Offer Notice, Owner shall have no obligation to submit such Transfer to Offeree.  If Owner desires to Transfer and such Transfer contains
a  Material  Modification,  then  prior  to  execution  of  a  letter  of  intent  or  purchase  and  sale  agreement,  whichever  occurs  first,  Owner  shall  provide  Offeree  with  a  written  notice  of  the  revised  economic
terms.  Offeree shall have five (5) business days to accept such revised terms by written notice to Owner.  Five (5) business days shall mean by 5:00 p.m. Pacific time on the fifth (5th) business day following
the submission of such revised economic terms to Offeree.  

1.2.

Termination  of  Right  of  First  Offer.    If  pursuant  to  this Agreement  Owner  completes  the  Transfer  of  the  Premises
described in the Offer Notice to a third party, then this Agreement and the ROFO set forth in the Lease shall terminate as to the Premises described in the Offer Notice.  This Agreement shall also terminate if
Offeree fails to close the purchase pursuant to the Purchase Agreement executed by Offeree and Owner, unless excused thereunder including as a result of Owner’s default.

breach  of  a  Sangamo  Third  Party  Agreement,  Pfizer
will  take  all  actions  and  provide  Sangamo  with  all

applicable cure period, then Pfizer may, at its election
and  in  its  sole  discretion,  act  reasonably  to  cure  such
breach  and  Sangamo  will  take  all  actions  and  provide
Pfizer with all cooperation to cure such breach, in each
case  as  reasonably  requested  by  Pfizer.  Further,  if
Pfizer  is  not  the  cause  of  such  breach,  then  Sangamo

5.3

Royalty Payments.

(a)

Royalty  Rates.    On  a
Product-by-Product  basis,  Pfizer  shall  pay  Sangamo
non-refundable,  non-creditable  royalties  based  on
annual  aggregate  Net  Sales  of  each  Product  in  the

Royalty Rate

Net sales up to and including [ * ]

Net sales above [ * ] up to and including [ * ]

Net sales above [ * ]

[ * ]%

[ * ]%

[ * ]%

Each Royalty Rate set forth in the table above will apply only to that portion of the Net Sales of a given Product in the
Territory  during  a  given  Pfizer Year  that  falls  within  the  indicated  range. An  example  calculation  of  royalties  under  this
Section 5.3(a) is set forth below.

By  way  of  example  only,  if  (i)  Pfizer,  its Affiliates  or  its  Sublicensees  sell  two  Products  in  the  Territory  during  a  given
Pfizer Year, (ii) Net Sales of the first Product in the Territory during such Pfizer Year are $[ * ] and (iii) Net Sales of the
second Product in the Territory during such Pfizer Year are $[ * ], then the royalties payable by Pfizer under this Section
5.3(a) during such Pfizer Year would be calculated as follows:

Royalty for first Product

royalty payment obligations under Section 5.3(a) shall
expire,  on  a  Product-by-Product  and  country-by-
country  basis, upon  the  latest  of:  (i)  the  expiration  of
the  period  during  which 
the  use  for  approved
Indications,  sale,  offer  for  sale  or  importation  of  such
Product  in  such  country  would absent  a  license  or
ownership  interest,  infringe  a  Valid  Claim  in  the
Licensed  Technology  in  such  country  (considering
Valid  Claims  of  pending  patent  applications  to  be
issued  with 
the
expiration  of  all  Regulatory  Exclusivity  for  such
Product in such country; and (iii) [  *  ]  years  after  the
First  Commercial  Sale  of  such  Product  in  any  Major
Market  Country  (the  “Royalty  Term”). 
  For  the
avoidance  of  doubt,  the  Royalty  Term  for  a  given

Term  for  any  Product  in  a  given  country,  no  further
royalties  will  be  payable  in  respect  of  sales  of  such
Product  in  such  country  and,  thereafter  the  license
granted to Pfizer under Section 2.1(a)(i) with respect to
such  Product  in  such  country  will  automatically
become  fully  paid-up,  perpetual, 
irrevocable  and
royalty-free.

(d)

Royalty Reductions. The
following  adjustments  will  be  made,  on  a  Product-by-
Product  and  country-by-country  basis,  to  the  royalties
payable pursuant to Section 5.3(a).

E n t r y.  For  any  Pfizer  Quarter  in  the  applicable
Royalty  Term  for  a  Product  in  a  country  in  the
Territory  during  which  (1)  a  Biosimilar  Product  with
respect  to  such  Product  is  being  sold  in  such  country;
and  (2)  the  unit  volume  of  such  Biosimilar  Product
sold in such country in such Pfizer Quarter exceeds [ *
]  of  the  combined  unit  volume  of  such  Product  and
such  Biosimilar  Product  sold  in  such  country  in  such
Pfizer  Quarter,  subject  to  Section  5.3(d)(vi),  the
royalties payable on Net Sales of such Product in such
country in such Pfizer Quarter would be reduced by [ *
] of the amounts of royalties otherwise payable on such
Net Sales pursuant to Section 5.3(a) for the remainder
of  the  applicable  Royalty  Term,  such  reduction  to  be
prorated appropriately in aggregate for the then-current
Pfizer  Quarter.    The  unit  volume  of  the  Product  and
Biosimilar Product shall be calculated using a mutually
acceptable  method  and  using  market  share  data
provided  by  a  reputable  and  mutually  agreed  upon
provider, such as IQVIA (f/k/a QuintilesIMS Health).

directly or through any Pfizer Affiliate or Sublicensee,
then, subject to Section 5.3(d)(vi),  Pfizer shall have the
right  to  deduct,  from  the  royalty  payment  that  would
otherwise  have  been  due  pursuant  to  Section  5.3(a)
with  respect  to  Net  Sales  of  such  Product  in  such
country in a particular Pfizer Quarter, an amount equal
to  [  *  ]  of  the  royalties  paid  by  Pfizer  to  such  Third
Party pursuant to such license on account of the sale of
such  Product  in  such  country  during  such  Pfizer
Quarter,  such  reduction  to  continue  with  any  amounts
not deducted carried over to future Pfizer Quarters until
all such amounts have been expended.

Expiry  of  Certain  Valid  Claim  Coverage .    If  with  respect  to  any  particular
Product in any particular country in the Territory, the Royalty Term for such Product in such country extends beyond the
date on which there is no Valid Claim Covering such Product with respect to its  sale, offer for sale or importation  in such
country,  then,  subject  to  Section  5.3(d)(vi),  the  royalties  payable  on  Net  Sales  of  such  Product  in  such  country  shall  be
reduced by [ * ] for each Pfizer Quarter for the remainder of the applicable Royalty Term.

No Adjustment  for  Certain  Sangamo  Third  Party Agreements .  Except  as  set
forth  in  Schedule  2.1(d),  Sangamo  will  be  solely  responsible  for  (i)  all  obligations  (including  any  royalty  or  other
obligations that relate to the Licensed Technology) under the Current Licenses and under the Exclusive Upstream Licenses
and (ii) all payments to inventors of Licensed Technology, including payments under inventorship compensation Laws.

operation of Sections 5.3(d)(i), (ii) or (iii) individually
or in combination shall not reduce by more than  [  *  ]
the royalties that would otherwise have been due under
Section  5.3(a)  with  respect  to  Net  Sales  of  such
Product in such country during such Pfizer Quarter.

and  agreed  between  the  Parties  that  any  payments
made under this Agreement are exclusive of any value
added  or  similar  tax  (VAT),  which  shall  be  added
thereon  as  applicable.    Where  VAT  is  properly  added

regulation  of  any  jurisdiction,  the  Party  making  such
payment shall deduct and withhold the amount of such
taxes  for  the  account  of  the  payee  to  the  extent
required  by  applicable  laws  or  regulations  and  such
amounts  payable  to  the  payee  shall  be  reduced  by  the
amount  of  taxes  deducted  and  withheld.  Any  such
withholding  taxes  required  under  applicable  laws  or
regulations to be paid or withheld shall be an expense
of, and borne solely by, the payee.

Party  making  such  payment  that  may  be  reasonably
necessary in order for such Party not to withhold tax or
to  withhold  tax  at  a  reduced  rate  under  an  applicable
bilateral  income  tax  treaty.    The  payee  sh all  use
reasonable efforts to provide any such tax forms to the
Party making the payment at least [ * ] prior to the due
date for any payments for which the payee desires that
the  Party  making  the  payment  apply  a  reduced

with  reasonable  assistance  to  enable  the  recovery,  as
permitted  by  Law,  of  withholding  taxes,  VAT,  or

of such action, then the sum payable by that Party (in
respect  of  which  such  deduction  or  withholding  is
required  to  be  made)  shall  be  increased  to  the  extent
necessary to ensure that the other Party receives a sum
equal to the sum which it would have received had no
such  action  occurred,  (ii)  otherwise,  the  sum  payable

by providing draft applications and responses, and that
Pfizer  may  employ  its  preferred  outside  counsel  and
patent agents to conduct such activities as required for
US and ex-US prosecution.

At  Pfizer’s  request  and  expense  (subject  to  the  next
sentence),  Sangamo  will  cooperate  and  assist  Pfizer
and  outside  counsel  and  agents  in  the  preparation  and
prosecution  of  such  Research  Program  Clinical

Research Program Clinical Candidate Patent Rights in
any country, Pfizer will provide Sangamo with written
notice  of  its  decision  not  less  than  [  *  ]  before  any
action  is  required.  If  Sangamo  elects  to  continue  such
prosecution or maintenance, (i) Sangamo will promptly
identify and engage the attorneys and agents who will

Pfizer  will  have  no  responsibility  with  respect  to  the
filing, prosecution or maintenance of, or any expenses
incurred  in  connection  with,  any  such  Research
Program  Clinical  Candidate  Patent  Rights  following
Pfizer’s  notice,  (iii)  Sangamo  will  not  disclose  any
Pfizer  Confidential  Information  in  connection  with
such  filing,  prosecution  or  maintenance  without
Pfizer’s prior written approval, not to be unreasonably
withheld, (iv) Sangamo will keep Pfizer advised on the
status  of  the  preparation,  filing,  prosecution,  and
maintenance  of  all  such  Research  Program  Clinical
Candidate  Patent  Rights  and  will  reasonably  consider

after  written  request  by  Pfizer,  by  written  notice  to

 
Pfizer  provide  a  status  report  of  all  such    Research
Program Clinical Candidate Patent Rights.

The  Parties  will  reasonably  cooperate  to  avoid  including  in  Research  Program  Clinical  Candidate  Patent  Rights  any
inventions  also  relevant  to  zinc  finger  proteins  active  against  targets  other  than  C9ORF72.    In  the  event  that  the  Parties
agree  such  invention  that  is  relevant  to  other  zinc  finger  proteins  should  be  disclosed  in  the  same  initial  filing  with  an
invention that is directed to Compounds, and such invention relevant to other zinc finger proteins is, [ * ], significant with
respect  to  Sangamo’s  business,  the  Parties  shall  cooperate  in  each  relevant  country  to  (A)  [  *  ],  which  for  avoidance  of
doubt may [ * ], (B) [ * ] which [ * ], or (C) take such other action as the

Zinc  Finger  Research  Program  Know-How  to  the
specification  in  any  refiling,  conversion  or  new  filing
of  a  Specified  Sangamo  Patent  Right  ([  *  ]),  and  (ii)
reflecting  any  reasonable  comments  offered  by  Pfizer
in  any  final  filings  submitted  by  Sangamo  to  any
relevant  patent  office  or  Governmental Authority.    If
Sangamo  elects 
the  prosecution  or
maintenance  of  any  Specified  Sangamo  Patent  Right,
Sangamo  will  provide  Pfizer  with  written  notice
immediately, but not less than [ * ] before any action is

Enforcement 

(a)

(i)

Each  Party  will
promptly  notify  the  other  in  the  event  of  any  actual,
potential  or  suspected  infringement  of  a  patent  under
the  Sangamo  Patent  Rights  or  the  Licensed  Research
Program Patent Rights by any Third Party.

(ii)

As 

between
Pfizer and Sangamo, Pfizer will have the first right, but
not  the  obligation,  to  institute  litigation  or  take  other
steps  to  remedy  infringement  in  connection  with  the
Research Program Clinical Candidate Patent Rights in
the  Territory  with  respect  to  activities  competitive  or
relevant  to  those  of  Pfizer  under  this  Agreement  (an
“RPCCPR  Infringement”),  and  any  such  litigation  or
steps  will  be  at  Pfizer’s  expense;  provided  that  any
infringement  recoveries  resulting  from  such  litigation
or  steps  relating  to  a  claim  of  RPCCPR  Infringement,
after  deducting  Pfizer’s  out  of  pocket  expenses
(including counsel fees and expenses) in pursuing such
claim,  will  be  [  *  ].  Pfizer  will  not,  without  the  prior
written  consent  of  Sangamo,  enter 
into  any
compromise  or  settlement  relating  to  such  litigation
that (i) admits the invalidity or unenforceability of any
Sangamo  Patent  Right  or  Research  Program  Patent
Right  or  (ii)  requires  Pfizer  or  Sangamo  to  abandon
any Sangamo Patent Right or Research Program Patent
Right.  Sangamo,  upon  request  of  Pfizer,  agrees  to
timely  commence  or  to  join  in  any  such  litigation,  at
Pfizer’s  expense,  and  in  any  event  to  cooperate  with
Pfizer  in  such  litigation  or  steps  at  Pfizer’s  expense.
Sangamo  will  have  the  right  to  consult  with  Pfizer
about  such  litigation  and  to  participate  in  and  be
represented by independent counsel in such litigation at
Sangamo’s own expense.  If Pfizer fails to institute and
prosecute  an  action  or  proceeding  to  abate  any
RPCCPR Infringement within a period of [ * ] after the
first  notice  of  such  RPCCPR  Infringement  under
Section  6.4(a)(i)  (or  such  shorter  period  as  may  be
necessary to bring or defend and maintain such action
without  loss  of  rights),  then  upon Pfizer’s  written
consent  (not  to  be  unreasonably  withheld),  Sangamo
shall  have  the  second  right,  but  not  the  obligation,  to
commence  a  suit  or  take  other  action  to  enforce  the
applicable Research Program Clinical Candidate Patent
Right  against  such  RPCCPR  Infringement  at  its  own
cost and expense.

Pfizer and Sangamo, Sangamo will have the first right,

a Third Party’s Manufacture, use, importation, offer for
sale or sale, or other exploitation, of any gene therapy
product  that  is  directed  to  C9ORF72  other  than  an
RPCCPR Infringement (an “C9ORF72 Infringement”),
and  any  such  litigation  or  steps  will  be  at  Sangamo’s
expense.  Pfizer,  upon  request  of  Sangamo,  agrees  to
timely  join  in  any  such  litigation,  at  Sangamo’s
expense,  and  in  any  event  to  cooperate  with  Sangamo
in such litigation or steps at Sangamo’s expense. Pfizer
will have the right to consult with Sangamo about such

litigation and to be represented by independent counsel
in such litigation at Pfizer’s own expense. If Sangamo
fails to institute and prosecute an action or proceeding
to abate any C9ORF72 Infringement within a period of
[  *  ]  after  the  first  notice  of  such  C9ORF72
Infringement  under  Section  6.4(a)(i)  (or  such  shorter
period  as  may  be  necessary  to  bring  or  defend  and
maintain such action without loss of rights), then upon
Sangamo’s  written  consent  (not  to  be  unreasonably
withheld),  Pfizer  shall  have  the  second  right,  but  not
the obligation, to commence a suit or take other action
to  enforce  the  applicable  Licensed  Research  Program
Patent  Right or  Sangamo  Patent  Right  against  such
C9ORF72  Infringement  at  its  own  cost  and  expense;
provided  that  any  infringement  recoveries  resulting
from  such  litigation  or  steps  relating  to  a  claim  of
C9ORF72 Infringement, after deducting Pfizer’s out of
pocket expenses (including counsel fees and expenses)
in pursuing such claim, will be deemed 1) [  *  ]  in the
case of assertion of Licensed Research Program Patent
Rights and  2)  [  *  ]  in  the  case  of  Sangamo  Patent
Rights.    For  avoidance  of  doubt,  Pfizer  shall  have  no
second  right 
to  remedy infringement  of  Licensed
Research  Program  Patent  Rights  or  Sangamo  Patent
Rights in  each  case  other  than  with  respect  to  a  gene
therapy product directed to C9ORF72.

Enforcement  of  Pfizer
Patent  Rights. Pfizer  will  have  the  sole  right,  but  no

notice to the Indemnified Party within [ * ] after receipt
of  notice 
the
commencement  of  or  assertion  of  any  Third  Party
Claim,  to  assume  the  direction  and  control  of  the
defense, 
settlement,  appeal  or  other
disposition of any such claim for which it is obligated
to indemnify the Indemnified Party (including the right
to  settle  the  claim  solely  for  monetary  consideration)
with  counsel  selected  by  the  Indemnifying  Party  and
reasonably  acceptable 
the  Indemnified  Party;
to 
provided that (a) the Indemnifying Party has sufficient
financial  resources,  to  satisfy  the  amount  of  any
adverse  monetary  judgment  that  is  sought,  (b)  the
claim  seeks  solely  monetary  damages  and  (c)  the
Indemnifying Party expressly agrees in writing that as
between  the  Indemnifying  Party  and  the  Indemnified
Party,  the  Indemnifying  Party  will  be  solely  obligated
to  satisfy  and  discharge 
in  full  (the
conditions set forth in clauses (a), (b) and (c) above are
collectively referred to as the “Litigation Conditions”).
The Indemnifying Party will be entitled, at its sole cost
and  expense,  to  assume  direction  and  control  of  such
defense,  with  counsel  selected  by  the  Indemnifying
Party  and  reasonably  acceptable  to  the  Indemnified

testimony  and  attending  such  conferences,  discovery

Joint Press Release

Sangamo and Pfizer announce collaboration for development of zinc finger protein
gene therapy for ALS

Richmond, California and New York, New York,  January 3, 2018 – Sangamo Therapeutics, Inc. (Nasdaq: SGMO) and
Pfizer Inc. (NYSE: PFE) today announced a collaboration for the development of a potential gene therapy using zinc finger
protein transcription factors (ZFP-TFs) to treat amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration
(FTLD) linked to mutations of the C9ORF72 gene.

ALS and FTLD are part of a spectrum of neurodegenerative disorders caused by mutations in the C9ORF72 gene that
involve hundreds of additional repetitions of a six base pair sequence of DNA. This ultimately leads to the deterioration of
motor neurons, in the case of ALS, or neurons in the frontal and temporal lobes, in the case of FTLD. Currently, there are
no cures to halt or reverse the progression of ALS or FTLD. The C9ORF72 mutation is linked to approximately one-third of
cases of familial ALS.

“We are excited to continue our collaborative relationship with Pfizer with this new program using Sangamo’s zinc finger
protein technology to develop a potential gene therapy for patients with certain forms of ALS and FTLD, devastating
diseases with very limited treatment options,” said Dr. Sandy Macrae, Chief Executive Officer of Sangamo. “The precision
and flexibility of zinc finger proteins enables targeting of virtually any genetic mutation. Collaboration with the right
partner for a given therapeutic application is a key component of our corporate strategy and enables us to pursue the vast
opportunity set of our platform.”

“We look forward to working with Sangamo on potential treatments for devastating diseases related to genetic mutations of
the C9ORF72 gene,” said Greg LaRosa, Senior Vice President and Chief Scientific Officer, Pfizer Rare Disease. “Pfizer is
proud of the progress we have made in the area of gene therapy, which offers tremendous promise to patients and their
families.”

Gene therapies are a potentially transformational technology for patients, focused on highly specialized, one-time
treatments that address the root cause of diseases caused by genetic mutation. Sangamo’s ZFP-TF technology involves
introducing an engineered zinc finger protein (ZFP) which is designed to identify and bind to a precise sequence of DNA.
Once bound to the target sequence of DNA, a transcriptional repressor domain attached to the ZFP suppresses

expression of the gene. Under this collaboration, Sangamo and Pfizer will investigate allele-specific ZFP-TFs with the
potential to differentiate the mutant C9ORF72 allele from the wild type allele and to specifically down-regulate expression
of the mutant form of the gene.

Under the terms of the collaboration agreement, Sangamo will receive a $12 million upfront payment from Pfizer.
Sangamo will be responsible for the development of ZFP-TF candidates. Pfizer will be operationally and financially
responsible for subsequent research, development, manufacturing and commercialization for the C9ORF72 ZFP-TF
program and any resulting products. Sangamo is eligible to receive potential development and commercial milestone
payments of up to $150 million, as well as tiered royalties on net sales.

In May 2017, Sangamo and Pfizer entered into an exclusive, global collaboration and license agreement for the
development and commercialization of potential gene therapy products for Hemophilia A, including SB-525, which entered
the clinic in August 2017.

About Sangamo’s ZFP-TF Gene Regulation Platform

Sangamo’s zinc finger protein transcription factor (ZFP-TF)-mediated gene regulation approach is designed to either
selectively repress (down-regulate) or activate (up-regulate) the expression of a specific gene or DNA sequence with a
single administration.  This technology enables targeting of a broad range of diseases requiring regulation of endogenous
gene expression and differs from other approaches such as gene therapy or zinc finger nuclease-mediated genome editing,
which are designed to replace or correct a missing or mutated gene or DNA sequence. Sangamo is developing ZFP-TFs as
a novel therapeutic approach for diseases of the central nervous system (CNS). In keeping with the company’s strategy to
externalize development of ZFP-TFs for CNS diseases, Sangamo has established collaborations with Pfizer for ALS and
FTLD and with Shire for Huntington’s disease. Sangamo is also developing ZFP-TFs to down-regulate the expression of
tau, a protein associated with Alzheimer’s disease and frontotemporal dementia (FTD). The company’s strategy for the tau
program is to seek a development and commercialization partner upon completion of preclinical studies.

About Sangamo Therapeutics  

Sangamo Therapeutics, Inc. is focused on translating ground-breaking science into genomic therapies that transform
patients' lives using the company's industry leading platform technologies in genome editing, gene therapy, gene regulation
and cell therapy. The Company is conducting Phase 1/2 clinical trials in Hemophilia A and Hemophilia B, and in lysosomal
storage disorders MPS I and MPS II. Sangamo has an exclusive, global collaboration and license agreement with Pfizer
Inc. for gene therapy programs for Hemophilia A, ALS and FTLD, with Bioverativ Inc. for hemoglobinopathies, including
beta thalassemia and sickle cell disease, and with Shire International GmbH to develop therapeutics for Huntington's
disease. In addition, Sangamo has established strategic partnerships with companies in non-therapeutic applications of its
technology, including Sigma-Aldrich Corporation and Dow AgroSciences. For more information about Sangamo, visit the
